Abstract

Provided is an apparatus for removing a bad odor from a toilet. The apparatus includes: a toilet body; and a water storing means for storing water to supply water to the toilet body according to an operation of a sensing means or a user command means including a lever, wherein the water storing means includes: a suction means which is directly or indirectly connected to the toilet body and suctions the air including an odor of the toilet body while the water is not supplied to the toilet body; and a discharging means for discharging the air suctioned by the suction means when the air is immersed in the water.

Claims

1. An apparatus for removing a bad odor from a toilet, comprising:

a water storing means comprising a water tank, in which;

a water supply pipe of a toilet is provided to pass therethrough;

an upper end or an upper portion of the water supply pipe is provided to be at a predetermined height from a bottom surface thereof;

a tap water pipe connected to a valve body is connected to one side thereof; and

an air hole is formed in an upper portion thereof;

a float which is connected to the upper portion of the water supply pipe and configured to open/close the water supply pipe and close the air hole by contacting the air hole when the water supply pipe is opened; and

an air suctioning/discharging means which is installed inside the water tank and comprises

a suction port connected to the water supply pipe, and

a discharge port which discharges odor-containing air supplied from the suction port,

wherein the discharge port is disposed at a position lower than the predetermined height at which the water supply pipe is disposed, discharges air while being immersed into water, and is operated according to operations of a detection means and a control means.

2. The apparatus of claim 1, wherein

one side of the water supply pipe and a suction port of an aspirator, which is a kind of the air suctioning/discharging means, are connected by means of a connection pipe, and

an odor is suctioned according to an operation of the aspirator.

3. The apparatus of claim 1, wherein

an air vent hole vertically passing through the float is formed in the float at a position corresponding to the air hole formed in the water storing means including the water tank, and

a valve (CK1) communicating with the air hole while being opened when contacting the air hole is installed on an upper end of the air vent hole.

4. The apparatus of claim 3, wherein the valve (CK1) comprises:

a fixed base inserted into and fixed to the upper end of the air vent hole;

a flow hole formed to pass through the fixed base;

a movable rod inserted into the flow hole;

a sealing plate fixed to the lower end of the movable rod;

a cylindrical cap detachably fixed to the fixed base;

an air outlet hole perforated in a portion of the circumference of the cap; and

an elastic spring interposed between the inner bottom surface of the cap and the lower surface of the sealing plate.

5. The apparatus of claim 3, wherein

the air hole comprises a contact plate, and

an upper end of the movable rod of the valve CK1 is pressed while contacting the contact plate and the air hole is thereby opened, and thus,

air is introduced into the air vent hole via the flow hole and the air outlet hole.

6. An apparatus for removing a bad odor from a toilet, comprising:

a toilet body;

a water controlling means comprising a valve body operated by a user command means including a lever; and

a water storing means provided between the toilet body and the water controlling means and comprising a water tank which is connected to the water controlling means to receive water and is connected to the toilet body to supply discharging water, wherein;

a water supply pipe is provided in the water storing means, is provided to pass through one side of the water storing means, has a lower portion or a lower side to which the toilet body is connected, has an upper portion, to which one side of a water level adjusting means including a float operated by the water supplied to the water storing means is connected, and supplies the discharging water to the toilet body according to an operation of the float;

an air suctioning/discharging means is provided to be connected to the water supply pipe;

the air suctioning/discharging means comprises a discharge port which discharges odor-containing air to the water storing means; and

the odor-containing air suctioned from the toilet body through the water supply pipe is discharged, through the discharge port immersed in the water, to the water storing means.

7. The apparatus of claim 6, wherein

an air hole is provided on one side of the water storing means, and

the air hole is provided in a position at which the air hole is opened/closed according to an operation of the float.

8. An apparatus for removing a bad odor from a toilet, comprising:

a toilet body;

a water controlling unit comprising a valve body operated to supply water through a tap water pipe to wash the toilet body by a user command unit including a lever or by a sensing means;

a water storing means provided between the toilet body and the water controlling unit and comprising a water tank configured to store a portion of water supplied through the tap water pipe to wash the toilet body;

a water discharge means comprising a connector formed in the water tank and connected to the water supply pipe of the toilet and is configured such that an upper end or an upper portion of the connector has a height from a bottom surface of the water tank, thereby discharging water to the toilet body through the connector and the water supply pipe while storing a portion of water supplied through the tap water pipe;

an air suctioning/discharging means comprising

a suctioning port connected to the connector of the water discharging means, and

a discharge port configured to discharge air containing odor supplied from the suctioning port, wherein the discharge port discharges the air while being immersed in the water and is operated according to an operation of a sensing means and a control unit; and

a water tank inner pressure adjusting means comprising an air hole on an upper portion of the water tank so that a constant inner pressure of the water tank is maintained to allow approximate equilibrium with an atmospheric pressure, and

a float brought into contact with the air hole due to a level of water stored in the water tank to thereby close the air hole.

9. The apparatus of claim 8, wherein the connector is disposed collinearly with the tap water pipe so as to be positioned directly under the tap water pipe connected to the water tank, and comprises:

a vertically passing-through water supply path formed in the connector such that the water supplied through the tap water pipe is directly supplied and discharged to the water supply pipe; and

a water branch path formed in the connector to cause water stream to branch such that a portion of the supplied water is stored in the water tank.

10. The apparatus of claim 8, comprising a partitioning wall which partitions an inside of the water tank such that the suction port of the air suctioning-discharging means and the air hole of the water tank inner pressure adjusting means are disposed in spaces separated from each other, wherein the partitioning wall is formed to protrude from an upper surface of the water tank and formed such that a lower end of the partitioning wall is separated from the bottom surface of the water tank, and an inner space of the water tank is divided by filing the separated portion with water.

11. The apparatus of claim 8, comprising an aspirator as the air suctioning/discharging means, wherein the aspirator comprising a suctioning pipe which has

an end connected to the connector, and

another end connected to the aspirator,

so that air containing odor of the toilet body is suctioned through the water supply pipe and the connector while water is not supplied to the toilet body, and

the suctioned air is discharged while being immersed in the water stored in the water tank.

12. The apparatus of claim 8, comprising an air bubble generator which is provided as the air suctioning/discharging means and comprises:

an air bubble generator main body which suctions air containing odor of the toilet body through the water supply pipe and the connector while water is not supplied to the toilet body, and discharges the suctioned air through the discharge port, wherein the air bubble generator main body is installed at a position which is not immersed in water; and

a suctioning pipe which has an end connected to the connector and another end connected to the air bubble generator main body so that the discharge port discharges the suctioned air while being immersed in the water stored in the water tank.
