Toilet having a built-in odor evacuating system
FIELD OF THE INVENTION
[001] The present invention relates generally to toilets but more particularly
to
a toilet having a built-in odor evacuating system.
BACKGROUND OF THE INVENTION
[002] Disagreeable odors are sometimes produced when someone uses the
toilet. Bathroom turbines only exasperate the problem by pulling the air
up and spreading it before exhausting it after a few minutes. Other
deodorizing systems all have shortcomings of one form of other.
SUMMARY OF THE INVENTION
[003] In view of the foregoing disadvantages inherent in the known devices
now present in the prior art, the present invention, which will be
described subsequently in greater detail, is to provide objects and
advantages which are:
[004] To provide for a a toilet having a built-in odors evacuating system.
[005] In order to do so, the invention comprises a toilet body wherein a tank
portion contains a module further comprised of a turbine member that is
CA 02929582 2016-05-11
powered by a DC motor, and triggered by a motion sensor. The turbine
member takes air from openings located inside a bowl portion of the
toilet body, and pumps the air through a first pipe, forming part of the
module. Once passed the turbine member, th.e air is directed into a
second pipe directing the air into a "P" trap extending integrally from the
bowl portion so that odors are blocked by water inside the bowl portion.
The built-in odors evacuating system operates according to the following
steps:
[006] a) Before use, a butterfly valve is closed, and a lever is in a first
position
and connected to the butterfly valve.
[007] b) When a user sits on a toilet seat, the motion sensor is triggered
which
actuates a servo motor which moves the lever into a second position,
which also opens the butterfly valve, and actuates the turbine member
which is powered by a low voltage DC motor, so that air is sucked in
directly from the bowl portion by way of the openings.
c) When a user presses on a four function flush button, the servo motor
turns the lever into a third position position which pulls on a chain,
which pulls a plug open so as to flush the toilet; simultaneously, the
lever closes the butterfly valve; the servo motor continues rotating the
lever, briefly reopening the butterfly valve until the lever reaches its
original first position, which closes the butterfly valve so as to prevent
any siphoning effect from water going down, passed the "P" trap, and
the second pipe.
[008] In a preferred embodiment, the first pipe has an inner volume
substantially larger than that of the second pipe so as to achieve low air
velocity for any given CFM so as to prevent water creeping.
CA 02929582 2016-05-11
[009] In yet another embodiment, the motion sensor is triggered only when the
lid cover is up while a donut member is down.
[0010] In still another embodiment, a four function flush button is coupled
with a
PCB so as to control:
[0011] a) a first level CFM from the turbine member;
[0012] b) a second CFM level higher than the first level CFM from the turbine
member;
[0013] c) actuating the servo motor to initiate a flushing action;;
an on/off switch.
[0014] Preferably the first level produce 13 CFM, and the second level
produces 15 CFM.
[0015] There is also a manual flush handle.
[0016] In still another embodiment, the motion sensor operates by way of a
combination of a hall effect sensor and a magnet so as to create an
on/off switch.
[0017] Optionally an LED lights up the bowl member in low light conditions.
[0018] There has thus been outlined, rather broadly, the more important
features of the invention in order that the detailed description thereof
that follows may be better understood, and in order that the present
CA 02929582 2016-05-11
contribution to the art may be better appreciated. There are additional
features of the invention that will be described hereinafter and which will
form the subject matter of the claims appended hereto.
[0019] In this respect, before explaining at least one embodiment of the
invention in detail, it is to be understood that the invention is not limited
in its application to the details of construction and to the arrangements of
the components set forth in the following description or illustrated in the

DETAILED DESCRIPTION
[0029] A built-in odor evacuating system (10) is comprised of a toilet body
(11)
wherein a tank portion (13) contains a module (12) further comprised of
a turbine member (22) that is powered by a DC motor (not shown) and
triggered by a motion sensor (14). The turbine member (22) takes air
from openings (16) located inside a bowl portion (18) of the toilet body
(11), and pumps it through a first pipe (20), forming part of the module
(12). Once passed the turbine member (22), it is pushed into a second
pipe (24) which directs the air into a "P" trap (26) extending integrally
from the bowl portion (18) so that the odors are blocked by the water
inside the bowl portion (18).
[0030] When not in use, the system (10) is in the configuration of fig. 2A
wherein
a butterfly valve is closed. When a user (not shown) sits on a toilet seat
(30), the motion sensor (14) is triggered which actuates a servo motor
(32) which moves a lever (34) into a horizontal position (fig. 2B) which
also opens the butterfly valve (28), and actuates the turbine member
(22), powered by a low voltage DC motor (not shown), so that air is
sucked in directly from the bowl (18) by way of the openings (16), which
are the same openings used by water when flushing, as is known in the
art of toilets.. When a user presses on a four function flush button (36).
The servo motor (32) turns the lever (34) into a vertical position which
pulls on a chain (35), which pulls a plug (38) open, as per figs. 20 and
CA 02929582 2016-05-11
4, so as to flush the water. At the same time, the lever closes the
butterfly valve (28). The servo motor (32) continues rotating the lever
(34), briefly reopening the butterfly valve (28) until it reaches its original
closed configuration as per fig. 2A so as to prevent any siphoning effect
from the water going down,.passed the "P" trap (26) and the second pipe
(24).
[0031] The first pipe (20) has an inner volume substantially larger than that
of
the second pipe (24) so as to achieve low air velocity for any given CFM.
This low velocity prevents any water from creeping up from it and into
turbine member (22) because the air uses the same conduits openings
(16) as the water.
[0032] The motion sensor (14) is only triggered when the lid cover (40) is up
while the donut (42) is down. In any other instances, the motion sensor
(14) is blocked and therefore is inoperative. A combination of a hall effect
sensor (44) and a magnet (46) create an on/off switch for the motion
sensor (14).
[0033] The four function flush button (36) is coupled with a PCB (48) in order
to
control: 1) a low 13 CFM from the turbine member (22) 2) a higher 15
CFM from the turbine member (22) 3) toilet flushing 4) an on/off switch
when cleaning or servicing the toilet (11).
CA 02929582 2016-05-11
[0034] A standard manual flush handle (50) can be used if a user prefers, or
in
the event of a power failure.
[0035] It is understood that there is wiring between the motion sensor (14)
,the
PCB (48), the servo motor (32), and a power source, generally house
current, although an optional battery could form part of the electrical
circuit in case of power outage. This type of electrical circuit is well
known in the art of electrical wiring and its details need not be discussed
herein.
[0036] An additional feature is the use of an LED (52) under the motion sensor
(14) for use at nighttime.
[0037] With respect to the above description then, it is to be realized that
the
optimum dimensional relationships for the parts of the invention, to
include variations in size, materials, shape, form, function and manner
of operation, assembly and use, are deemed readily apparent and
obvious to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention. Therefore, the
foregoing is considered as illustrative only of the principles of the
invention. Further, since numerous modifications and changes will
readily occur to those skilled in the art, it is not desired to limit the
invention to the exact construction and operation shown and described,
CA 02929582 2016-05-11
and accordingly, all suitable modifications and equivalents may be
resorted to, falling within the scope of the invention.
