conditions held in the notification condition holder 76. The
notification condition holder 76 stores the error code
indicating the type of occurring abnormalities, and a subject
that should be notified of the occurrence of the abnormality
and a priority of notification in association with each
other. When the occurrence of the abnormality is detected by
the abnormality detector 62, the notifier 63 refers to the
notification condition holder 76 to obtain the notification
destination to which the occurring abnormality should be
notified, and refers to the toilet information database 71
and the notification destination information database 72 to
acquire the notification destination information. The
notifier 63 may notify a notification destination having a
highest priority of the occurrence of the abnormality
according to a priority of notification, and may notify a
notification destination having a second highest priority of
the occurrence of the abnormality when there is no response
from the notification destination having the highest priority
or when the notification destination does not respond to a
call even when the call is originated, attempt to notify the
notification destination having the highest priority of the
occurrence of the abnormality plural times, or perform both
of the notification to the notification destination having
the second highest priority and the notification to the
LXL-70106W0

CA 03091721 2020-08-19
14
notification destination having the highest priority in
parallel. The notifier 63 may notify a plurality of
notification destinations in parallel at the same time.
[0026] Details of the abnormality to be detected and a
specific example of the notification destination will be
described below.
[0027] The abnormality detector 62 may determine that
the abnormality occurs when the use situation information
indicating the use situation of the toilet bowl device 30
matches the conditions held in the abnormality detection
condition holder 75. For example, the abnormality detector
62 may determine that the abnormality occurs when acquiring
the information indicating that the amount of water inside
the bowl of the toilet bowl device 30 exceeds a predetermined
value. If sewage overflows from the bowl due to clogging of
a drainage pipe, the sewage may have a great influence not
only on the inside of the toilet room 21 but also on the
surroundings thereof, so it is very important to organize a
system that promptly detects the overflow of the sewage and
notifies an appropriate subject that can take necessary
measures for operating facilities and the like.
[0028] The amount of water in the bowl of the toilet
bowl device 30 may be detected by the water level sensor
installed on an inner surface or an outer surface of the bowl
of the toilet bowl device 30. When the water level sensor is
installed on the outer surface of the bowl, a contactless
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
water level sensor such as a capacitance type may be
installed. In addition, the contactless water level sensor
such as the capacitance type may be installed on an outer
surface of a trap provided between a drainage port at a lower
5 portion of the bowl and the drainage pipe. After the toilet
bowl device 30 is used and then the bowl is washed with
washing water and the sewage is drained, pooled water remains
in the bowl at a portion below an upper end of the trap, but
even after a predetermined time elapses from drainage, when
10 the water level sensor installed on the outer surface of the
trap detects that water remains at the upper end of the trap,
it is estimated that the sewage in the bowl is not drained
from the drainage pipe due to the clogging of the drainage
pipe, and as a result, it may be determined that an
15 abnormality occurs.
[0029] When
the sewage actually overflows from the bowl,
since it is necessary to clean the toilet room 21 and perform
a measure or the like that temporarily limit an access of a
user to the toilet room 21 and the surroundings thereof, the
notifier 63 notifies a subject in charge of cleaning the
toilet room 21 in which the toilet bowl device 30 in which
the abnormality occurs is installed and a subject managing
the toilet room 21 of the occurrence of the abnormality. In
addition, when it is estimated from other information or the
like that the cause of the occurrence of the abnormality is
due to a malfunction of the equipment such as the toilet bowl
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
16
device 30, a subject that manufactures the toilet bowl device
30 in which the abnormality occurs may also be notified of
the occurrence of the abnormality, may be requested to
provide information on equipment or facilities in which the
malfunction occurs, or may take orders for parts. In
addition, when it is estimated from other information or the
like that the cause of the occurrence of the abnormality is
due to a malfunction of equipment or facilities such as a
drainage pipe or a pump, a subject in charge of maintenance
of equipment or facilities of the drainage pipe or the pump
may also be notified of the occurrence of the abnormality and
may be requested to repair or replace the equipment or
facilities.
[0030] When the abnormality that sewage overflows from
the bowl is detected in the toilet bowl device 30 installed
in the toilet room 21 installed on an upper floor of a
building having a plurality of floors, the notifier 63 may
notify a subject managing floors below a floor on which
toilet room 21 is installed or a subject managing stores
around a floor on which the toilet room 21 is installed of
the information on the abnormality, in addition to a subject
managing the floor on which the toilet room 21 is installed.
When sewage actually overflows, since there is a risk that
the sewage spreads to the floor of the toilet room 21 and is
infiltrated into a ceiling below the floor, or water is
leaked from a ceiling of a downstairs, a subject managing the
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
17
downstairs or the surroundings thereof may be notified of the
abnormality, so it is possible to takes promptly necessary
measures and to suppress the influence to the minimum.
[0031] The notifier 63 may notify the abnormality
notification means 27 installed inside or around the toilet
room 21 of the occurrence of the abnormality. As a result, a
user who is about to enter the toilet room 21 to use the
toilet room 21 or a user of the facility 20 around the toilet
room 21 can be notified that the abnormality has occurred in
the toilet room 21, can be prevented from entering the toilet
room 21, or can be urged to move away from an area around the
toilet room 21. In addition, it is possible to make a person
in charge of stores or the like around the toilet room 21
take appropriate measures such as ventilation and
notification. In addition, it is possible to promptly notify
a person in charge who goes around the toilet room 21 that
the abnormality occurs in the toilet room 21.
[0032] According to such a technology, it is possible to
significantly shorten the time required to take appropriate
measures after the occurrence of the abnormality, so the
influence of the abnormality can be minimized. In addition,
since the toilet room 21 can be appropriately maintained and
managed, the convenience of the user of the facility 20 can
be improved, and the comfort and operation conditions of the
facility 20 can be improved.
[0033] The abnormality detector 62 may determine that
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
18
the abnormality occurs when the use situation information
indicating the operation conditions of the controller 31 for
the user of the toilet bowl device 30 to input the operation
instruction to the toilet bowl device 30 matches the
conditions held in the abnormality detection condition holder
75. For example, the abnormality detector 62 may determine
that the abnormality occurs when acquiring the information
indicating that the same button of the controller 31 is
continuously operated plural times. When a button for
performing a function that is not assumed to be continuously
performed plural times is continuously operated plural times,
since there is a problem in the button or the configuration
for performing the function thereof and it is estimated that
the user's desired function is not performed, it may be
determined that the abnormality occurs in the controller 31
or the toilet bowl device 30 operated by the controller 31.
The abnormality detection condition holder 75 may hold, as
the conditions, a type of operable buttons, the number of
times of operation of the button determined as abnormal, an
operation interval of the button in which it is determined
that the button is continuously operated in association with
each other. In the buttons that are assumed to be
continuously operated plural times such as a button for
changing a volume of a sound masking device for the toilet,
the number of times of operation of the button determined as
abnormal may more increase than that of other buttons.

CA 03091721 2020-08-19
19
[0034] In the state in which the seating sensor of the
toilet bowl device 30 does not detect the seating, when the
information indicating that a button for performing a private
part cleaning function is pressed is acquired, it is
estimated that the seating sensor or the button is broken, so
it may be determined that the abnormality occurs.
[0035] When the information indicating that the button
for stopping the private part cleaning function is not
pressed for a predetermined time after the private part
cleaning function of the toilet bowl device 30 is performed
is acquired, it is estimated that the private part cleaning
function or the button is broken, so it may be determined
that the abnormality occurs.
[0036] When the communication is regularly performed
between the controller 31 and the toilet bowl device 30, if
the information indicating that the controller 31 and the
toilet bowl device 30 cannot communicate for a predetermined
time or longer is acquired, it is estimated that the
communication function of controller 31 or the toilet bowl
device 30 is broken, the controller 31 has fallen or has been
taken out and thus is out of a communicable coverage with the
toilet bowl device 30, or a state of charge of a battery of
the controller 31 is insufficient, so it may be determined
that the abnormality has occurred.
[0037] The notifier 63 notifies the subject managing the
toilet room 21 in which the controller 31 or the toilet bowl
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
device 30 in which the abnormality occurs is installed and
the subject in charge of maintenance of the controller 31 or
the toilet bowl device 30 of the occurrence of the
abnormality. In addition, when it is estimated from other
5 information that the controller 31 or the toilet bowl device
in which the abnormality occurs needs to be repaired or
replaced, the subject that manufactures the controller 31 or
the toilet bowl device 30 may also be notified of the
occurrence of the abnormality and take orders for necessary
10 parts.
[0038] In this way, it is possible to promptly detect
and notify the abnormality that is difficult for a person in
charge of management to find even after going around the
toilet room 21 based on the operation conditions of the
15 controller 31 and take necessary measures, so the convenience
of the user of the toilet room 21 can be improved, and the
comfort and the operation conditions of the facility 20 can
be improved.
[0039] When a function to change a temperature of the
20 toilet seat or a temperature of hot water for private part
cleaning stops by an administrator, and when the information
indicating that a button for changing the temperature is
operated a predetermined number of times or more is acquired,
the subject managing the toilet room 21 can be notified that
25 it is estimated that many users desire to change the
temperature.
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
21
[0040] In this way, it is possible to estimate the
request of the user of the toilet bowl device 30 from the
operation conditions of the controller 31 and notify the
management subject of the estimated request, so the
environment of the toilet room 21 can be improved and the
convenience of the user can be improved.
[0041] When the use situation information indicating the
state of facilities or equipment installed inside or around
the toilet room 21 matches the conditions held in the
abnormality detection condition holder 75, the abnormality
detector 62 may determine that the abnormality has occurred.
For example, the abnormality detector 62 may determine that
the abnormality has occurred when acquiring the information
indicating that the time it takes for the door 23 of the
toilet room 21 or the door 25 of the private room 24 to be
closed and then reopened is less than a predetermined value.
The abnormality detector 62 calculates statistical values
such as an average staying time from a staying time history
of the private room 24 or the toilet room 21 for each private
room 24, each toilet room 21, or each facility 20 to
calculate a predetermined value for determining that the
abnormality has occurred.
[0042] When the user stays in the toilet room 21 or the
private room 24 for the predetermined time, since there is a
risk that the user may be in a poor physical condition, the
notifier 63 notifies a subject managing the toilet room 21 in
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
22
which the abnormality has occurred of the occurrence of the
abnormality and notifies the subject to rush to the toilet
room 21. In addition, when it is estimated from another
information or the like that the malfunction of the door 23
or the door 25 or the malfunction of the opening/closing
sensor of the door 23 or the door 25 occurs, the subject in
charge of the maintenance of the toilet room 21 with the
malfunction is notified of the occurrence of the abnormality.
In addition, when it is estimated from other information or
the like that the door 23, the door 25, or the
opening/closing sensor in which the abnormality occurs needs
to be repaired or replaced, the subject that manufactures the
door 23, the door 25, or the opening/closing sensor may also
be notified of the occurrence of the abnormality and takes
orders for necessary parts.
[0043] As a result, since it is possible to promptly
detect the case where the abnormality occurs and take
appropriate measures even when the abnormality occurs in the
user of the toilet room 21, the user can safely use the
toilet room 21 and the facility 20 and the comfort and
operating conditions of the facility 20 can be improved.
Further, the abnormality of the facility or equipment
installed inside or around the toilet room 21 as well as the
toilet bowl device 30 can be detected promptly, so that the
toilet room 21 can be appropriately maintained and managed.
[0044] The abnormality detector 62 may determine that
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
23
the abnormality has occurred in the toilet bowl device 30 or
the facility or equipment installed inside or around the
toilet room 21 when a combination of any two or more of the
pieces of information held in the use situation information
holder 73 matches the predetermined conditions. The notifier
63 notifies the subject in charge of managing the toilet room
21 of the occurrence of the abnormality, and when it is
estimated that the facility or equipment needs to be
repaired, replaced, or the like, the notifier 63 requests the
subject in charge of maintenance of the facility or equipment
to repair or replace the facility or equipment with the
abnormality, and may order the necessary parts to the subject
that manufactures the facility or equipment.
[0045] When the information indicating that the door 23
of the toilet room 21 or the door 25 of the private room 24
is closed for the predetermined time or longer, and the
toilet bowl device 30 installed in the toilet room 21 or the
private room 24 is not used for the predetermined time or
longer is acquired or when the information indicating that
the door 23 of the toilet room 21 or the door 25 of the
private room 24 is not opened even when the toilet bowl
device 30 is used and then the predetermined time or more
elapses is acquired, there is a risk that the abnormality has
occurred in the user, so it may be determined that the
abnormality has occurred.
[0046] When the door 23 of the toilet room 21 or the
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
24
door 25 of the private room 24 is closed and then the toilet
bowl device 30 is not used, and the door 23 or the door 25 is
opened before the predetermined time elapses, it is estimated
that the toilet bowl device 30 malfunctions or the toilet
bowl device 30, the private room 24, or the toilet room 21 is
dirty and the toilet bowl device 30 cannot be used, so it may
be determined that the abnormality has occurred.
[0047] When the door 25 of the private room 24 is open
and the information indicating that the toilet bowl device 30
is used is acquired, it is estimated that the opening/closing
sensor of the door 25 or the toilet bowl device 30
malfunctions, so it may be determined that the abnormality
has occurred.
[0048] When the toilet bowl device 30 is not used for a
predetermined time or longer, it may be determined that the
abnormality has occurred in the toilet bowl device 30 or in
the toilet room 21 in which the toilet bowl device 30 is
installed. The predetermined time may be calculated from the
past usage frequency of the toilet bowl device 30 or the
toilet room 21.
[0049] In the toilet bowl device 30 equipped with a hot
water tank for private part cleaning, if the temperature of
the hot water in the hot water tank does not change more than
the predetermined value even though the private part cleaning
function is executed, it is estimated that a valve for the
hot water tank, a private part cleaning nozzle, or the like
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
is broken, so it may be determined that the abnormality has
occurred.
[0050] The abnormality detection conditions as in the
above example may be automatically acquired by machine
5 learning. For example, the contents of the abnormality when
the abnormality actually occurs and the use situation
information at that time are collected from the plurality of
facilities 20, the toilet room 21, and the toilet bowl device
30, and the relationship between the use situation
10 information and the contents of the abnormality may be
learned by performing supervised learning using these actual
data as teacher data. This machine learning may be executed
by a server device or may be executed by a plurality of
computers using a technology such as cloud computing. The
15 learned condition may be delivered to the management device
50 at any time and stored in the abnormality detection
condition holder 75. The management device 50 may include a
learner that executes the machine learning. In this case,
the learner acquires, from the notification destination
20 notifying the abnormality detected by the abnormality
detector 62, information on whether or not the abnormality
actually has occurred or the information such as the contents
of the abnormality, the state of the toilet room 21, the
toilet bowl device 30, or the like, the taken measures, and
25 the results of the measures when the abnormality has
occurred, and may further learn abnormality detection
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
26
conditions by executing the supervised learning using these
pieces of information and the use situation information when
it is determined that the abnormality has occurred as the
teacher data to update the abnormality detection condition
holder 75.
[0051] In this way, according to the technology of the
present embodiment, even if an abnormality occurs in the
toilet room 21 or the toilet bowl device 30, it is possible
to promptly detect the abnormality, notify the appropriate
notification destination of the detected abnormality, and
take necessary measures, so the influence of abnormality can
be suppressed to the minimum. Further, since the occurrence
of the abnormality is detected based on the information that
can be collected from the toilet room 21 or the toilet bowl
device 30, it is possible to suppress the cost of newly
installing a sensor or the like for detecting the
abnormality.
Cooperative Control of Plurality of Toilet Bowl Devices
[0052] Next, as a feature of the management device 50 of
the present embodiment, a technology of comprehensively
managing the plurality of toilet bowl devices 30 installed in
the toilet room 21 and instructing the plurality of toilet
bowl devices 30 to execute a predetermined operation or
function will be described. The instruction determiner 64
determines timing to instruct the toilet bowl device 30 to
execute predetermined operation or function based on the use
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
27
situation information of the plurality of toilet bowl devices
30. The instruction transmitter 65 transmits an instruction
to the toilet bowl device 30 at the timing determined by the
instruction determiner 64 to execute the predetermined
operation or function.
[0053] Fig. 5 illustrates a configuration of the toilet
bowl device according to an embodiment. The toilet bowl
device 30 includes a communication device 33 and a control
device 34. The communication device 33 controls
communication with other devices. The communication device
51 may perform communication by using any wired or wireless
communication method. The communication device 51
communicates with the communication device 22 via the wired
communication, transmits the use situation information of the
toilet bowl device 30 to the management device 50, and
receives an instruction to the toilet bowl device 30 from the
management device 50.
[0054] The control device 34 includes an instruction
receiver 35, a sensor information acquirer 36, and a control
unit 37. These functional blocks can be realized in various
forms such as only hardware or a combination of hardware and
software.
[0055] The instruction receiver 35 receives an
instruction to execute the predetermined operation or
function from the management device 50. The sensor
information acquirer 36 acquires the detected information
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
28
from various sensors such as the seating sensor, the
temperature sensor, and the water level sensor that are
provided in the toilet bowl device 30. The control unit 37
controls functions such as the drainage and private part
cleaning of the toilet bowl device 30 based on the
information detected by various sensors acquired by the
sensor information acquirer 36, and also executes the
predetermined operation or function based on the instruction
received by the instruction receiver 35.
[0056] The instruction determiner 64 of the management
device 50 refers to the past use situation of the toilet bowl
device 30 held in the use situation information holder 73 to
determine timing to instruct the toilet bowl device 30 to
execute the predetermined operation or function. For
example, the toilet bowl device 30 may be instructed to turn
on a heating function of the toilet seat before a
predetermined time when the facility 20 is opened. In
addition, the toilet bowl device 30 may be instructed to turn
off the heating function of the toilet seat before or after a
predetermined time when the facility 20 is closed. The
toilet bowl device 30 may be instructed to change the
temperature of the toilet seat according to a date and time,
a season, weather, outside temperature, room temperature, and
the like.
[0057] When the instruction determiner 64 causes the
plurality of toilet bowl devices 30 to execute a
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
29
predetermined operation or function that consumes power of a
predetermined value or more, the instruction determiner 64
determines timing to instruct the toilet bowl device 30 to
execute the predetermined operation or function so that the
predetermined number or more of the toilet bowl devices 30 do
not execute the operation or function at the same time. For
example, since the function of turning on a heater in the
toilet seat requires relatively large power, the plurality of
toilet bowl devices 30 may be instructed with a time
difference so as not to exceed power supply capacity or
contract amperage of the facility 20.
[0058] When the instruction determiner 64 causes the
plurality of toilet bowl devices to execute a predetermined
operation or function involving water supply or drainage, the
instruction determiner 64 determines timing to instruct the
toilet bowl device 30 to execute the predetermined operation
or function so that the predetermined number or more of the
toilet bowl devices 30 connected to the same water supply
pipe or drainage pipe do not execute the operation or
function at the same time. For example, since the function
of cleaning the toilet bowl involves draining a relatively
large amount of washing water, the plurality of toilet bowl
devices 30 may be instructed with a time difference so as not
to exceed the capacity of the drainage pipes installed in the
toilet room 21 and the facility 20.
[0059] The instruction determiner 64 determines timing
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
to instruct the toilet bowl device 30 to execute the
predetermined operation or function involving the drainage so
that among the plurality of toilet bowl devices 30 connected
to the same drainage pipe, the toilet bowl device 30
5 connected to an upstream side of the drainage pipe has a
drainage frequency, a time, or a drainage volume more than
those of the toilet bowl device 30 connected to a downstream
side thereof. In order to prevent a urine stone from
adhering to the toilet bowl device 30 and clogging of the
10 drainage pipe, in the case of regularly performing the
function of cleaning the toilet bowl device 30, since
drainage flows from the toilet bowl device 30 on the upstream
side to the drainage pipe on the downstream side, sufficient
drainage flows to the drainage pipe on the downstream side
15 even if the cleaning frequency of the toilet bowl device 30
on the downstream side is low, but only drainage flows from
the toilet bowl device 30 to the drainage pipe on the
upstream side. Therefore, by increasing the cleaning
frequency, the time, or the drainage volume of the toilet
20 bowl device 30 connected to the drainage pipe on the upstream
side more than those of the toilet bowl device 30 connected
to the drainage pipe on the downstream side, it is possible
to appropriately clean the drainage pipe on the upstream side
and the drainage pipe on the downstream while suppressing
25 washing water from being unnecessarily consumed.
[0060] According to such a technology, when the
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
31
management device 50 collectively controls the plurality of
toilet bowl devices 30 remotely, it is possible to reduce the
malfunctions that can occur when a plurality of toilet bowl
devices 30 perform the same function all at once and smoothly
and appropriately cooperate and remotely control the
plurality of toilet bowl devices 30.
[0061] In executing the predetermined operation or
function, the control unit 37 of the toilet bowl device 30
inquires of the management device 50 whether or not other
toilet bowl devices 30 executing the operation or function
exist around the toilet bowl device 30. The responder 66 of
the management device 50 acquires information on the
executing operation or function from the plurality of toilet
bowl devices 30 and stores the acquired information in the
use situation information holder 73, checks whether other
toilet bowl devices 30 that are executing the predetermined
operation or function exist around the toilet bowl device 30
when the toilet bowl device 30 inquires whether or not other
toilet bowl devices 30 that are executing the predetermined
operation or function exist around the toilet bowl device 30,
and returns a response to the check. The control unit 37 of
the toilet bowl device 30 determines whether or not to
execute the operation or function or timing to execute the
operation or function according to the response from the
management device 50. For example, in executing a
predetermined operation or function involving drainage, the
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
32
control unit 37 inquires of the management device 50 whether
or not other toilet bowl devices 30 that are executing the
operation or function exists around the toilet bowl device
30, and stops or postpones the execution of the operation or
function when there is a response from management device 50
that the other toilet bowl devices 30 exist.
[0062] According to such a technology, even when each
toilet bowl device 30 is operated independently, it is
possible to reduce the malfunctions that may occur due to
interference with the surrounding toilet bowl devices 30 and
operate the toilet bowl devices 30 in appropriate cooperation
with each other.
Control of Each Toilet Bowl Device
[0063] Next, as a feature of the management device 50 of
the present embodiment, a technology of instructing each
toilet bowl device 30 to execute the predetermined operation
or function will be described. The instruction determiner 64
determines the contents and timing of the predetermined
operation or function executed by the toilet bowl device 30
based on the use situation information of the toilet bowl
device 30. The instruction transmitter 65 transmits an
instruction to the toilet bowl device 30 at the timing

Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
34
management device 50 to stop the cleaning drainage function,
the control unit 37 of the toilet bowl device 30 stops the
cleaning drainage function, and does not drain the washing
water even when a toilet bowl cleaning lever or a toilet bowl
flushing button is operated by a user.
[0068] As described above, the situation where a
management subject, a cleaning subject, and maintenance
subject of the toilet bowl device 30 as well as the user of
the toilet bowl device 30 most want to avoid is the situation
where sewage overflows from the toilet bowl device 30.
According to the toilet management system 10 of the present
embodiment, when any abnormality is detected, particularly
when the water level sensor or the like detects that the
water level in the bowl is a predetermined value or greater,
or when an abnormality that may be a cause of the overflowing
of sewage such as the clogging of the toilet bowl device 30
is detected, the cleaning drainage function of the toilet
bowl device 30 forcibly stops, and as a result, it is
possible to prevent the sewage from overflowing from the
toilet bowl device 30 and suppress the pollution due to the
sewage to the minimum.
[0069] As described above, the abnormality detector 62
may detect an abnormality when the value of the water level
sensor provided in the toilet bowl device 30 exceeds the
predetermined value. In this way, it is possible to prevent
the sewage from overflowing from the bowl by causing the
LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19

sewage actually overflows or is about to overflow. Further,
the abnormality detector 62 may detect the abnormality based
on the detection result of the sensor other than the water
5 level sensor, the use situation information of the toilet
bowl device 30, and the like. For example, the sensor that
detects the sound or vibration may be installed near the
drainage pipe, and the abnormality may be detected based on
the detected sound or vibration after the cleaning drainage
10 function is executed by the toilet bowl device 30. In this
case, the abnormality detector 62 may detect the abnormality
when the sound or vibration that should be generated when the
sewage flows through the drainage pipe even if the cleaning
drainage function is executed is not generated, previously
15 hold reference data such as intensity, duration, frequency
and pattern of the sound or vibration that normally occurs
when the sewage flows through the drainage pipe, compare the
sound or vibration actually detected by the sensor with the
reference data, and detect the abnormality when the
20 difference from the reference data exceeds the predetermined
range. As a result, it is possible to accurately detect the
abnormality of the drainage pipe or the like regardless of
whether or not the water level of the toilet bowl device 30
is abnormal, and it is possible to prevent the sewage from
25 overflowing from the bowl by causing the toilet bowl device
30 to drain the washing water.

[0070] The instruction determiner 64 may calculate the
amount of washing water that can be added to the toilet bowl
based on the value of the water level sensor without the
overflowing of the sewage from the bowl, and limit the amount
of washing water to the calculated amount of washing water to
instruct the toilet bowl device 30 to execute the cleaning
drainage function. As a result, it is possible to attempt to
prevent the clogging of the drainage pipe by additionally
introducing the washing water into the bowl while preventing
the sewage from overflowing.
[0071] When the abnormality of the toilet bowl device
30, the clogging of the drainage pipe, or the like is
detected while the toilet bowl device 30 is executing the
cleaning drainage function, the instruction determiner 64 may
instruct the toilet bowl device 30 to stop the executing
cleaning drainage function. As a result, it is possible to
minimize the overflowing of the sewage even during the
execution of the cleaning drainage function.
[0072] When the abnormality of the clogging of the
drainage pipe or the like is detected, the instruction
determiner 64 may instruct all the toilet bowl devices 30
draining the sewage to the drainage pipe to stop the drainage
function. As a result, even when the toilet bowl device 30
itself has no abnormality, it is possible to prevent the
sewage from overflowing by causing the toilet bowl device 30
to drain the washing water.

LXL-70106W0
Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
41
that the predetermined time elapses after the cleaning
drainage function stops, that it is detected that the
abnormalities such as the clogging of the drainage pipe are
reduced or eliminated based on the use situation information
of various sensors or equipment, and the like. As a result
of the investigation by the applicant, it is known that most
of the causes of the clogging of the drainage pipe in a
toilet of a commercial facility, a public facility, or the
like are due to the pouring of a large amount of toilet paper
into the toilet at a time, but since the toilet paper is
formed to be easily released in water, if the cleaning is
made again after a while, the clogging due to the pouring of
the toilet paper, which is the cause of the clogging of the
drainage pipe may be eliminated. Therefore, the instruction
determiner 64 instructs the toilet bowl device 30 to execute
the cleaning drainage function and tries to clear the
clogging of the drainage pipe when the predetermined time
elapses after the abnormality is detected or after the toilet
bowl device 30 is instructed to stop the cleaning drainage
function. When it is detected that the clogging of the
drainage pipe is eliminated by the re-cleaning, the
instruction determiner 64 instructs the toilet bowl device 30
to withdraw the stop instruction of the cleaning drainage
function and resume the normal operation, and instructs the
toilet bowl device 30 and the abnormality notification means
27 to end the presentation that the abnormality has occurred,

Date Recue/Date Received 2020-08-19

CA 03091721 2020-08-19
42
the cleaning drainage function has stopped, and the
abnormality detection has been notified. When it is detected
that the clogging of the drainage pipe is not eliminated even
by the re-cleaning, the toilet bowl device 30 may be
instructed to execute the cleaning drainage function after a
predetermined time elapses. As a result, it is possible to
eliminate the abnormality by automatically coping with most
of the cases where the drainage pipe is clogged, so it is
possible to significantly reduce the man-hours of the
management subject, the cleaning subject, and the maintenance
subject. Further, the abnormality of the toilet bowl device
30 can be eliminated early and the toilet bowl device 30 can
be used, so it is possible to improve the convenience of the
user.
[0079] The relationship with the problems between the

toilet paper pours into the toilet at a time, the instruction
determiner 64 instructs the toilet bowl device 30 to execute
the cleaning drainage function when it is detected that a
predetermined amount or more of toilet paper is used in order
5 to reduce the pouring of a large amount of toilet paper into
the toilet at one time. The control unit 37 of the toilet
bowl device 30 executes the cleaning drainage function to
forcedly pour the toilet paper into the drainage pipe. The
use of the predetermined amount or more of toilet paper may
10 be detected by, for example, the sensor installed in the
toilet paper holder, or by a load cell, a passage sensor, a
camera, or the like installed inside or near the bowl. In
the former case, for example, the amount of the toilet paper
used may be detected by detecting a rotation amount of roll-
15 shaped toilet paper. In the latter case, the amount of
toilet paper used is detected based on a weight of the toilet
paper put into the bowl, the amount of toilet paper that
passes through the passage sensor, an image obtained by
capturing of the toilet paper put into the toilet bowl, or
20 the like. When the cleaning drainage function is
automatically executed, the presenter 83 may present to the

46
poured at a time. As a result, it is possible to reduce the
situation where the drainage pipe is clogged due to the
pouring of a large amount of toilet paper at a time, so it is
possible to significantly suppress the occurrence of the
abnormality in the toilet bowl device 30. Therefore, the
man-hours of the management subject, the cleaning subject,
and the maintenance subject can be significantly reduced, and
the convenience of the user can be improved.
(9) Check If User Is in Toilet in Which Abnormality Has
Occurred
[0088] When the abnormality of the toilet bowl device 30
is detected by the abnormality detector 62, the notifier 63
checks whether the user is in the private room 24 in which
the toilet bowl device 30 is installed based on the
information acquired by the use situation information
acquirer 61, and notifies the cleaning subject terminal 42 of
the checked result. As a result, the cleaning subject can
know whether or not it is possible to enter the private room
24 to clean the toilet bowl device 30 in which the
abnormality occurs, so the cleaning efficiency can be
improved. The instruction determiner 64 may instruct the
toilet bowl device 30 to present the user to leave a room

the abnormality early. Such problems can be solved by the
above-described abnormality detection/notification technology
of the toilet or (7) the re-cleaning technology, (8) the
automatic cleaning technology according to the amount of
toilet paper used, or the like, among the individual toilet
control technologies.
[0092] Since the cleaning subject also needs to perform
daily cleaning work, the cleaning subject wants to reduce the
time and effort required for additional cleaning accompanied
by the occurrence of the abnormality. In addition, even if
an abnormality occurs, the cleaning subject wants to cope
with the abnormality at a time zone of a fixed routine as
much as possible. Furthermore, the cleaning subject wants to
avoid immediately rushing to the toilet in which the
abnormality has occurred. Such problems can be solved by the

frequently used toilet room 21 is suppressed while clearly
maintaining the toilet room 21 where dirt is likely to occur,
and as a result, it is possible to reduce the man-hours and
burden on the person in charge of cleaning. In addition,
since the cleaning frequency and contents of the toilet room
21 can be changed automatically and dynamically, the burden
on the subject who manages the toilet room 21 can be reduced.
