DOCKING STATION FOR COUPLING AUTONOMOUS VACUUM TO
CENTRAL VACUUM
TECHNICAL FIELD
This document pertains generally, but not by way of limitation, to a system
for autonomously gathering debris in a space within an autonomous vacuum
system
and autonomously disposing of the gathered debris.
BACKGROUND
Autonomous or robotic vacuum cleaners commonly comprise a self-
propelled vacuum unit that autonomously travels through a space vacuuming
debris
from the floor onto an onboard storage space or bin. Typically, the robotic
vacuum
units are significantly smaller than conventional vacuum cleaners to permit
the
robotic units to more maneuver around and beneath obstacles and unobtrusively
parking when not in use. However, the comparatively smaller size of the
robotic
units that the internal components, such as the internal debris bin, be
correspondingly miniaturized. Also, robotic vacuum units also include
components
not ordinarily found in conventional vacuum cleaners, such as batteries or
movement systems, requiring further miniaturization of the other internal
components. As such, a common drawback of robotic vacuum units is that the
small
internal debris bin quickly fills and must frequently be emptied, typically by
hand.
Failing to properly or regularly emptying the internal debris bin reduces the
efficiency of the vacuum unit for gathering debris can be diminished, or the
vacuum
unit may cease to gather debris if the debris bin is full. As vacuum units are
typically programmed to clean at times when people are absent from the space
or
sleeping, the vacuum units can fill the debris bin before the intended
cleaning is
complete forcing a pause in cleaning until emptying of the debris bin. The
frequent
manual emptying of the debris bin can be inconvenient and can create unplanned
pauses in the cleaning process if the debris bin is insufficiently or
infrequently
emptied. Similarly, opening the debris bin to empty the bin often exposes the
1
CA 2979885 2017-09-22
collected debris to the air allowing the dust and other debris to be released,
which
can reduce the overall air quality within the space.
OVERVIEW
The present inventors have recognized, among other things, that a problem
to be solved can include regularly and efficiently emptying debris from a
robotic
vacuum unit. In an example, the present subject matter can provide a solution
to this
problem, such as by providing an autonomous vacuum system that can move about
a space collecting debris and configured to couple to a central vacuum that
can draw
collected debris into a remote intake port to the central vacuum. The
autonomous
vacuum system can move about the space in a predetermined pattern or randomly
within a bounded area collecting debris from the floor of the space. After the
autonomous vacuum system has filled an internal collection bin or after a
predetermined time, the autonomous vacuum system can be maneuvered to couple
the autonomous vacuum system to the remote intake port of the central vacuum.
The
central vacuum can be operated to create a central airflow drawing debris
collected
within the internal collection bin to empty the collection bin.
In an example, an autonomous vacuum system for collecting debris in a
remote space can comprise a collection bin fluidly connected to a debris
intake. The
autonomous vacuum system can further include an onboard vacuum operable to
generate a suction airflow from the debris intake into the collection bin to
the
onboard vacuum to draw debris through the debris intake into the collection
bin.
The autonomous vacuum system can further comprise an output connector fluidly
connected to the collection bin. The output connector can be coupled to a
remote
intake port fluidly connected to a central vacuum operable to generate a
central
airflow to draw debris from the collection bin into the remote intake port
positioned
in the remote space.
The movement system can move the autonomous vacuum system between a
docked position in which the output connector is coupled to the remote intake
port
and an undocked position in which the output connector is decoupled to the
remote
2
CA 2979885 2017-09-22
intake port. The onboard vacuum can generate the suction airflow to draw
debris
through the debris intake into the collection bin when the autonomous vacuum
system is in the undocked position. The onboard vacuum can generate the
suction
airflow and the central vacuum configured to generate the central airflow when
in
the docked position to agitate debris within the collection bin.
In an example, a central vacuum system for collecting debris within a remote
space can include an autonomous vacuum system and a central vacuum fluidly
connected to a remote intake port, the central vacuum being operable to
generate a
central airflow into the remote intake port. The autonomous vacuum system can
comprise a collection bin fluidly connected to a debris intake and further
include an
onboard vacuum operable to generate a suction airflow from the debris intake
into
the collection bin to the onboard vacuum to draw debris through the debris
intake
into the collection bin. The autonomous vacuum system can further comprise an
output connector fluidly connected to the collection bin. The output connector
can
be coupled to a remote intake port fluidly connected to a central vacuum
operable to
generate a central airflow to draw debris from the collection bin into the
remote
intake port positioned in the remote space.
The central vacuum system can include a dock for receiving the autonomous
vacuum system. The dock can comprise a docking port fluidly connected to the
remote intake port and at least one alignment feature. The at least one
alignment
feature can be configured to engage the autonomous vacuum system to align the
output connector with the docking port.

present patent application. It is not intended to provide an exclusive or

DETAILED DESCRIPTION
As depicted in FIG. 1, an autonomous vacuum system 20, according to an
example of the present disclosure, can comprise a housing 22, an onboard
vacuum
24, and a collection bin 26. The onboard vacuum 24 can be operated to generate
a
suction airflow into a debris intake 28 defined by the housing 22, through the
collection bin 26, and out an exterior vent 30 defined by the housing 22.
Debris can
be entrained in the suction airflow proximate the debris intake 28 and
deposited in
the collection bin 26. In an example, the autonomous vacuum system 20 can
include
at least one intake roller 32 rotatable to agitate debris on the floor
proximate the
debris intake 28 to facilitate entrainment of the debris in the suction
airflow created
by the onboard vacuum 24. The rotation of the at least one intake roller 32
can also
draw debris into the debris intake 28 for entrainment of the debris in the
suction
airflow created by the onboard vacuum 24. In certain examples, the at least
one
intake roller 32 can include a cutting device, a mechanical comb or rake, or
combinations thereof for cutting or separating clumps of debris as debris is
drawn
into the debris intake 28.
As depicted in FIG. 1, in an example, the autonomous vacuum system 20
can include a filter 34 positioned between the collection bin 26 and the
onboard
vacuum 24. The filter 34 can permit the suction airflow to pass through the
filter 34
while capturing debris entrained the suction airflow and capturing the debris
in the
collection bin 26. As illustrated in FIG. 3, the onboard vacuum 24 can be
operated
to generate a reverse airflow into the exterior vent 30, across the filter 34,
and into
the collection bin 26. The reverse airflow can free debris captured in the
filter 34 to
push the debris into collection bin 26. In at least one example, the at least
one intake
5
CA 2979885 2017-09-22
roller 32 can be rotated in a reversed direction to facilitate the generation
of the
reverse airflow. In certain examples, the onboard vacuum 24 and/or the at
least one
intake roller 32 can be operated to generate the reversed airflow for a
predetermined
time period, operated in a pulsed sequence, or cycled between the suction
airflow
and the reverse airflow to loosen debris captured in the filter.
In an example, the autonomous vacuum system 20 can include at least one
material collection sensor for monitoring the volume or amount of debris
collected
by the autonomous vacuum system 20. The autonomous vacuum system 20 can
include infrared, optical, laser or other sensors positioned proximate the
debris
intake 28 for monitoring debris entering through the debris intake 28. The
autonomous vacuum system 20 can have weight, pressure, or other sensors
connected to the collection bin 26 for monitoring debris captured within the
collection bin. The material collection sensor can monitor the debris
collected for a
variety of metrics including, but not limited to debris collected over certain
time
periods, operational cycles, and spaces to be cleaned.
In certain examples, the autonomous vacuum system 20 can communicate
with a central computer of a home automation system to provide analytics of
the
debris collected by the autonomous vacuum system. The home automation system
can signal the autonomous vacuum system 20 to alter the programming of the
autonomous vacuum system 20 to alter the spaces to be cleaned, the cleaning
path,
the order of the cleaning, the duration or frequency of the cleaning, and
other
operational parameters of the autonomous vacuum system 20. The altered
programming can cause the autonomous vacuum system 20 to focus the operation
of
the autonomous vacuum system in more critical areas improving battery life,
reduce
mechanical wear on the machine, reduce maintenance, and other advantages. The
home automation system can aggregate the collected information to direct the
user
to areas of the space that could require deeper cleaning with manual vacuum,
steam
cleaner, or carpet shampooer system. The home automation system can provide
other analytics including, but not limited to the percentage of debris picked
up by
the robotic vacuum vs. percentage picked up directly with the central vacuum.
6
CA 2979885 2017-09-22
In an example, the autonomous vacuum system 20 can include an evaluation
sensor for determining the debris content. For example, the evaluation sensor
can
determine if the debris includes, for example, dust, dust mites, pollen,
allergens,
fecal material, and other materials. The autonomous vacuum system 20 can alter
the
cleaning pattern, frequency and other parameters according to the content of
the
debris. In certain examples, the autonomous vacuum system 20 can cease
cleaning if
dangerous or hazardous materials are detected in the debris to avoid
potentially
spreading the debris around during the cleaning process. The autonomous vacuum
system 20 can also signal the user or a home automation system if dangerous
materials are detected in the debris.
In an example, the autonomous vacuum system 20 can include at least one
environmental sensor for monitoring conditions within the space as the
autonomous
vacuum system 20 moves through the cleaning process. The environmental sensor
can gather the information about temperature, humidity, air quality, and other
environmental information. In this configuration, the autonomous vacuum system
operates as a remote environmental sensor for the home automation system. The
home automation system 20 can use the collected information to operate other
devices such as, but not limited to bathroom ventilation fans, kitchen range
hoods,
balancing ventilation fans or dampers, HVAC systems, or other systems to
improve
20 air quality, alter air temperature or other environmental factors.
In an example, the autonomous vacuum system 20 can include an air
purifying device operably coupled to the environmental sensors. The air
purifying
device can be operated to purify air proximate the autonomous vacuum system 20
upon detection of poor air quality or within a designated area to act as a
local air
purifier. The autonomous vacuum system 20 can be configured to use the air
purifier during normal cleaning or parked within a designated space to operate
as a
local air purifier.
As depicted in FIG. 2, a central vacuum system 50, according to an example
of the present disclosure, can include the autonomous vacuum system 20 and a
central vacuum 52 fluidly connected to at least one remote intake port 54. The
7
CA 2979885 2017-09-22
central vacuum 52 can be fluidly connected to the at least one remote intake
port 54
with ducting. The central vacuum 52 can be operated to generate a central
airflow
entering through the remote intake port 54 and out an exterior vent 56. In
this
configuration, the autonomous vacuum system 20 can include an output connector
36 permitting access to the collection bin 26. As illustrated in FIG. 2, the
autonomous vacuum system 20 can be maneuvered to couple the output connector
36 to the remote intake port 54. The central vacuum 42 can be operated to
entrain
debris within the collection bin 26 within the central airflow and draw the
debris
into the remote intake port 54 to empty the collection bin 26. In an example,
central
vacuum tools and accessories can be coupled to the remote intake port 54 when
the
autonomous vacuum system 20 is undocked from the remote intake port 54 for
conventional operation of the central vacuum system 50.
In an example, the remote intake port 54 can include a contact sensor for
detecting connection of the autonomous vacuum system 20 to remote intake port
54.
The contact sensor can comprise an electrical connection, a proximity switch,
a
Hall-effect sensor, a mechanical sensor, or other conventional sensing means
for
detecting connection of the output connector 36 with the remote intake port
54.
Upon detection of the connection of the autonomous vacuum system 20, the
central
vacuum 52 is operated to create the central airflow. In this configuration,
the contact
sensor can also detect attachment of the central vacuum tools and accessories
to the
remote intake port 54 and signal the central vacuum 52 to create the central
airflow.
In certain examples, the contact sensor can determine if the autonomous vacuum
system 20 is coupled to the remote intake port 54 or other tools and
accessories are
coupled to the remote intake port 54.
In an example, the connection bin 26 can include a bin output valve 38 that
can selectively obstruct the output connector 36. The bin output valve 38 can
move
between a closed position preventing airflow through the output connector 36
and
an open position permitting airflow through the output connector 36. In
certain
examples, the bin output valve 38 can bias toward the closed position, wherein
coupling the remote intake port 54 to the output connector 36 moves the bin
output
8
CA 2979885 2017-09-22
valve 38 into the open position permitting airflow through the remote intake
port 54
and output connector 36. The weight, velocity, or mechanical apparatus of the
autonomous vacuum system 20 can be used to move the bin output valve 38 to the
open position. In at least one example, the bin output valve 38 can include a
spring
loaded pivoting damper mounted on a pivoting hinge. The pivoting damper is
biased
toward a closed position by the spring to obstruct the output connector 36,
wherein
engagement of the output connector 36 to the remote intake port 36 pivots the
pivoting damper to an open position to permit airflow through the output
connector
36.
In an example, the bin output valve 38 can be motorized or otherwise
controlled to manually close the bin output valve 38 while the central vacuum
52 is
being operated to close off the collection bin 26 from the central airflow.
The bin
output valve 38 can be closed upon receiving a predetermined trigger signal.
The
trigger signal can be a time-based delay or a measurement of debris within a
collection bin 26. The debris measurement can be a pressure switch, an optical
sensor or other conventional system for determining the amount of debris
within the
collection bin 26 or if the collection bin 26 has been emptied. The central
vacuum
52 can be deactivated upon detection of the change in pressure from the
closing of
the bin output valve 38 and/or upon receiving a transmitted off signal from
the
remote intake valve 54. The transmitted off signal can be transmitted by hard
wiring, wireless signal, or other communication means or protocol.
As depicted in FIG. 4, in an example, the connection bin 26 can define a bin
intake 40 through which the suction air flow enters the collection bin 26 from
the
debris intake 28. In certain examples, the connection bin 26 can include a bin
intake
valve 42 that can selectively obstruct the bin intake 40. In this
configuration, the bin
intake valve 42 can close when the central vacuum 52 is drawing the central
airflow
through the remote intake port 54 to improving the vacuum within the
collection bin
26 and efficient emptying of the collection bin 26.
As illustrated in FIG. 3, in an example, the onboard vacuum 24 can be
operated to generate a reverse airflow into the exterior vent 30, across the
filter 34,
9
CA 2979885 2017-09-22
and into the collection bin 26. The central vacuum 52 can be simultaneously
operated to generate a central airflow entering through the remote intake port
54 and
out an exterior vent 56. In this configuration, debris captured in the filter
34 can be
freed and drawn through the remote intake port 54 to empty the collection bin
26
and clear the filter 34. In certain examples, the onboard vacuum 24 and the
central
vacuum 52 can be simultaneously operated to create a reverse airflow. In this
configuration, the reverse airflow can clear debris from the debris intake 24,
the
collection bin 26, the filter 34, and other internal portions of the
autonomous
vacuum system 20.
As depicted in FIG. 4, in an example, the collection bin 26 includes at least
one jet opening 46 permitting one-way airflow into the collection bin 26
through the
underside of the collection bin 26. In this configuration, operating the
onboard
vacuum 24 to generate the suction airflow and/or the central vacuum 52 to draw
the
central airflow through the remote intake port 54 draws a jet airflow through
the jet
openings 46. The jet airflow can prevent settling debris or break up the
settled
debris within the collection bin 26 to facilitate entrainment of the debris
into the
central airflow. In certain examples, the bin intake valve 42 can be closed to
prevent
air from entering air through the bin intake 40 to facilitate the drawing of
the jet
airflow through the jet openings 46.
As depicted in FIGS. 5-8, in an example, the collection bin 26 can include at
least one internal wall 48 dividing the collection bin 26 into a plurality of
subsections. The internal walls 48 can divide debris entering the collection
bin 26
through the bin intake 40 among the subsections to prevent or limit clumping
of
debris within the collection bin 26. The internal walls 48 can be oriented
toward
output connector 36 such that debris within the collection bin 26 are funneled
toward the output connector 36 as the central airflow is drawn through the
remote
intake port 54. The internal walls 48 can be straight as illustrated in FIG. 6
or curved
as illustrated in FIG. 8. In an example, the collection bin 26 can be curved
or
otherwise shaped to minimize or eliminate acute angle corners, ribs,
protrusions, or
other structures that can collect or trap debris within the collection bin 26
when the
CA 2979885 2017-09-22
central airflow is drawn. In an example, the collection bin 26 can include a
shaker
element to agitate the collection bin 26 to loosen debris within the
collection bin 26.
As depicted in FIG. 9, in an example, the central vacuum system 50 can
include a dock 60 at the remote intake port 54. The dock 60 can include a
docking
port 62 fluidly connected to the remote intake port 54 and at least one
alignment
feature 64 for engaging the housing 22 of the autonomous vacuum system 20. The
at least one alignment feature 64 engages the housing 22 of the autonomous
vacuum
system 20 to align the output connector 36 with the docking port 62 as the
moving
autonomous vacuum system 20 into connection with the dock 60.
In an example, the dock 60 can be connected to an existing remote intake
port 54 to provide a docking port 62 compatible with the autonomous vacuum
system 20. In this configuration, the dock 60 can be plumbed in below or
adjacent to
an existing remote intake port 54. The dock 60 can be connected to the remote
intake port 54 by a flexible hose or other connector permitting providing the
dock
60 as an accessory of the central vacuum system 50.
As depicted in FIG. 12, in an example, the autonomous vacuum system 20
can further include an onboard power supply 59 for powering the internal
blower 24
and other internal systems of the autonomous vacuum system 20. The autonomous
vacuum system 20 can include at least one device contact for receiving an
electrical
current to charge the onboard power supply 59. In this configuration, the dock
60
can include at least one dock contact positioned to contact the device contact
when
docking the autonomous vacuum system 20 to the dock 60. The dock contact can
be
configured to provide the electrical current to the at least one device
contact for
charging the onboard power supply. In certain examples, the dock 60 can be
configured to provide electrical current to the onboard power supply 59 by
induction, contact connections, mechanical plug connections, or other
conventional
means of releasably coupling the onboard power supply 59 to the dock 60 to
provide
electrical current. In certain examples, the dock 60 can be wirelessly
connected or
physically connected to the autonomous vacuum system 20 when docked to provide
11
CA 2979885 2017-09-22
software updates or otherwise alter the programming of the autonomous vacuum
system 20.
As depicted in FIG. 10, in an example, the dock 60 can be positioned in a
garage housing 64 defining an internal space. The garage housing 64 can have a
garage door 66 moveable between an open position permitting access to the
internal
space and a closed position obstructing access to the internal space. In an
example,
the garage door 66 is positioned to define a ramp for the autonomous vacuum
system 20 when rotating the garage door 66 into the open position. In certain
examples, the garage housing 64 can be mounted beneath a cabinet to conceal
the
garage housing 64 beneath the cabinet.
As depicted in FIG. 11, in an example, the collection bin 26 can include a
debris door 70 that can be opened to permit emptying debris from collection
bin 26.
The central vacuum system 50 can include a floor port 72 for receiving debris
emptied from the debris door 70. In this configuration, the autonomous vacuum
system 20 can be moved over the floor port 72 empty debris from the collection
bin
26 into the floor port 72. When the autonomous vacuum system 20 is not
positioned
over the floor port 72, debris can be manually swept into the floor port 72.
The
debris sensor can be configured to operate the central vacuum system 50 when
debris is manually swept into the floor port 72 such that the debris is
entrained in the
central airflow.
As depicted in FIG. 12, the autonomous vacuum system 20 can include an
interchangeable module 80 including the collection bin 26 and the onboard
power
supply 59. The interchangeable module 80 can be coupled to the autonomous
vacuum system 20 such that the interchangeable module 80 aligns the filter 34,
the
outtake connector 36, and the bin intake 40 to fluidly connect the collection
bin 26
within the interchangeable module 80 to the internal blower 24 and a connected
central vacuum 52. In this configuration, the collection system 20, the
housing 22 of
the autonomous vacuum system 20 can define a module slot 82 for receive the
interchangeable module 80. In certain examples, the interchangeable module 80
can
include a filter output 84, a secondary connector opening 86, and a secondary
bin
12
CA 2979885 2017-09-22
intake 88 corresponding to the filter 34, the output connector 36, and the bin
intake
40. As illustrated in FIG. 12, the secondary connector opening 86 and the
secondary
bin intake 88 can include a corresponding valve for containing debris within
the
collection bin 26 when the interchangeable module 80 is removed from the
module
slot 82.
As illustrated in FIG. 13, in an example, the autonomous vacuum system 20
can include at least a first interchangeable module 80A receivable within a
first
module slot 82A and a second interchangeable module 80B receivable within a
second module 82B. One or both of the first and second interchangeable modules
80A, 80B can be coupled to the autonomous vacuum system 20. In this
configuration, the autonomous vacuum system 20 can be operated with only the
first
interchangeable module 80A or the second interchangeable module 80B coupled to
the autonomous vacuum system 20. This configuration permits the other of the
first
interchangeable module 80A or the second interchangeable module 80B to be
removed and emptied while the autonomous vacuum system 20 continues to
operate.
As illustrated in FIG. 14, in an example, the autonomous vacuum system 20
can decouple from the dock 60 and travel about a space along a predetermined
path
or randomly within the space. The autonomous vacuum system 20 can return to
the
dock 60 to empty the collection bin 26 upon expiration of a predetermined time
period corresponding to the filling of the collection bin 26. In certain
examples, the
autonomous vacuum system 20 can return to the dock 60 if the at least one
material
collection system determines that a sufficient volume or amount of debris
collected
by the autonomous vacuum system is sufficient to fill the collection bin 26.
The
autonomous vacuum system 20 can be programmed to immediately reverse upon
decoupling from the dock 60 to collect any debris that may have been freed
upon
decoupling of the autonomous vacuum system 20 from the dock 60.
