SYSTEME DE VENTILATION DE TOILETTES INTERIEUR

INTERIOR TOILET VENTILATION

Abrégé anglais

In existing system of ventilation of toilets the bad
smell spreads in whole volume of space of toilet room and then
is exhausted by ventilation. In this invention ,the
smell is exhausted from the source of bad smell directly
to the ventilation system.

IT'dTRODUCTION
1. ~r'Jhy do people use perfumes '?
i7~iost people- men ,women ,and sometimes children - use
perfumes ,scents,,body spr~~.ys, speed sticks, mouth washing
lic~uids,chewing gums and so on in thier private and socis,l

to them but : All people do not like bad smell .
2. V'there is the main course of bad smell
The system of our bodies according to thermodynamics
definition is an. open system, it weans that our bodies need
to interchange materials and energy to the surrending
environment, j~~Je breath , eat , drin'_: ~,nd we need to go
to the toilet several times in a day,- but sometimes v~re
do not like of being in toilets in home, restaurants, office,
hotel, bec~~use of bad s.~el1
Is the venti'~.ation system working '?
You see the ventil~.tor is working but it ce.:n not exh~.ust

SPECIFICATION
1. This invention relat~s.to a ventilation system of
toilet.
2.. In existing system of ventilation one or some, electric
fans exhaust air of toilet room . The vents of ventilatiam:
system are in the walls or ceiling and fir from the source
of bad smell. Turbulence of air spreads the smell in whole
volume of room of toilet and then exhaust by ventilation..
The nose and the clothes of person in the toilet are
exposured of smell the excrement and uriwe ,sometimes
there i~s deposit of molecules of these smells on the
clothes . B~ resort to the invention difficulties and
inconveniences to be improved.
3.. I have found these disadvantages may be overcome by
providing a new toilet seat and its components or ehangiing
the design of toilet and using new components. Sueh seat
and components permit the air of toilet bowl exhaustes
directly to the ventilation system without mixing with the
air of toilet room.
4. Full description of inventive idea .
I have two diffrent models for doing the duty.
MODEL 1.. In this model (FIG..4) movable toilet seat
(PART 2) is attached to the fixed part 1..

Two p~:~.rts are empty .. Toilet seat has a gap, three windows
in view of bottom «.nd <~, vent between two parts . The gap
of seat is for entering fresh air into toilet bowl and is
crooked since with this sh~.pe the entering air is trended
to the internal sides and the probable particles of excrement
are deposited on the internal sides of toilet and only air
miffed with smell exhaust by windows . Each window has a
plastic farce and about: one centimeter of hook and loop
fastener in two sides and chang~.ble air filter of plastic
fibers that sticks to the fasteners .. The surface of windows
have the angle of 30 respect with to the surface of seat for
reducing of deposit the particles on the filters . There is
a g~~.te between two parts with cross sectian of rectangular.
Part of 1 can be made of PVC (Preferly white colour ) ,
Toilet seat (Part2) should be made of galvanized plate steel
or stainless steel or hard plastic because its inside is
empty . The part 1 has a connector , elbo and flexible pipe
for connecting to ventilation system .. The speed of air
inside the system should be slow for prevention of deposite
the particles on the filters .
T~Io del 2
This model (Fig. 5) after installation does not wave . It. has
only one window , changable air filter with hool.~ and loop
f~~~.stener , connector and flexible pipe for connecting to the
ventilation system .. This model can be made of PVC .
P~odel 3 : This model{Fig 6) is suitable for using in urinal .:
Activation of ventilator
v~Te can activate ventilator by connecting its circuit to the
circuit of toilet room light or using sensor {motion detector
switch with tuner and so on) with low voltage about 5 volts
for activation the ventilator circuit with 120 volts .
