According to the invention of claim 1, since the air flow b is generated from the water injection port 10 of the toilet body 2 to the water intake port 11 in the direction opposite to the water flow a, the existing water flow passage 9 is formed. Can be exhausted using. Further, since the air flow b can be generated during defecation, the deodorizing effect is high.

Exhaust is performed from a location above the water level at the time of intake around the intake 11, so that water does not enter the exhaust pipe 21. According to the second aspect of the invention, the air flow b is generated from the toilet body 2 to the exhaust pipe 21 by driving the fan 22, and the odor generated in the toilet is the water inlet 1 of the toilet body 2.
The water is sucked into the flow path 9 from 0, passes through the vacant chamber 20, and is discharged from the exhaust pipe 21. Although water invades into the vacant chamber 20 during washing with water, since the exhaust pipe 21 is connected above the water level at the time of water intake, the water does not enter the exhaust pipe 21.

According to the third aspect of the invention, since the exhaust pipe 21 is connected to the sealing member 23 between the toilet body 2 and the water tank 3, the toilet body 2 is subjected to processing such as punching for exhaust. There is no need to do it. Therefore, it can be easily attached to an existing toilet bowl.

According to the fourth aspect of the invention, since the opening 17a of the overflow pipe 17 connected to the water intake pipe 14 is closed by the float valve 24, the air flow b containing odor flows into the water tank 3. Furthermore, it does not flow into the room.

When water overflows in the water tank 3, the float valve 24 floats up from the opening 17a and opens the opening 17a. Therefore, the overflowed water flows from the overflow pipe 17 into the toilet body 2 through the intake pipe 14. Is discharged.

Is provided. A water tank 3 is provided around the water intake 11.
The seat 12 is formed.

In the water tank 3, an automatic water supply stop valve (not shown) utilizing the buoyancy of floating balls for controlling the amount of water from the water supply pipe 7 is provided. By this automatic water supply stop valve, a certain amount of water A is stored in the water tank 3.

Further, as shown in FIG. 2, the water tank 3
A drain valve 13 for supplying the water in the water tank 3 to the water intake 11 of the toilet body 2 is provided at the bottom of the. The drain valve 13 contacts the water intake pipe 14 extending from the water tank 3 to the water intake 11 of the toilet body 2, a valve seat 15 formed on the upper part of the water intake pipe 14, and the valve seat 15. Floating ball 1
6 is provided. An overflow pipe 17 is connected to the water intake pipe 14 for removing excess water when an overflow occurs in the water tank 3. The float ball 16 is rotatably connected to an overflow pipe 17 via a lever 18, and the operation lever 8 is connected to the chain 1.
They are connected via 9. As a result, when the operating lever 8 is operated during washing with water, the floating ball 16 is pulled away from the valve seat 15, and the water A in the water tank 3 flows into the intake pipe 14 and from there, inside the flow passage 9 of the toilet body 2. It will be jetted as a water flow a from the water injection port 10 into the concave hole 4 through. When the inside of the water tank 3 becomes empty, the floating ball 16 returns to the valve seat 15 to close the water intake pipe 14, and the water A is again stored in the tank 3.

The deodorizing method according to the present invention utilizes the water intake 11, the flow passage 9, the water inlet 10 and the like of the above-mentioned sitting stool, and from the water inlet 10 of the toilet body 2 to the water inlet 11. The air flow b is generated in the direction opposite to the water flow a, and the air is discharged to the outside of the toilet body 2 from a location above the water level around the water intake 11 at the time of water intake.

In order to use this method, the toilet body 2
An exhaust pipe 21 is connected to a vacant chamber 20 around the water intake pipe 14 of the water intake pipe 14 above the water level at the time of water intake.

The air flow b drawn by the fan 22 also flows toward the intake pipe 14, and the overflow pipe 17,
There is a risk of returning to the room via the water tank 3. In order to prevent this, as shown in FIGS. 4 and 5, the opening 17a of the overflow pipe 17 is closed by a float valve 24 that shuts off the air flow b. The float valve 24 includes a float ball 25 that closes the opening 17a of the overflow pipe 17,
A guide rod 26 is attached to the floating ball 25, and the guide rod 26 is slidably inserted in a guide cylinder 27 fixed in the overflow pipe 17. The guide cylinder 27 is connected to the inner surface of the overflow pipe 17 by a plurality of arms 28 extending radially from the guide cylinder 27. Then, the float valve 24 does not open the opening 17a of the overflow pipe 17 due to the air flow b rising in the overflow pipe 17, prevents the odor from entering the water tank 3, and prevents the excess water in the tank 3. When generated, the buoyancy causes the opening 17a.
The excess water is flowed into the overflow pipe 17 away from the overflow pipe 17.

Next, a method of using this seat-type toilet will be described. When using the toilet, the fan 22 is activated. As a result, from the water inlet 10 of the toilet body 2 to the water inlet 1
The air flow b is generated in the direction opposite to the water flow a toward 1, and the odor generated in the toilet body 2 is discharged to the outside of the toilet through the existing water flow passage 9. Further, the opening 17a of the overflow pipe 17 connected to the water intake pipe 14 is closed by the float valve 24, so that the air flow b containing odor flows into the water tank 3 and does not further flow into the room. Therefore, the toilet bowl can be used comfortably.

When cleaning the toilet bowl, the operating lever 8 is operated and the float 16 is removed from the valve seat 15 of the water intake pipe 14. As a result, the water A in the water tank 3 flows into the water intake pipe 14, flows from the water inlet 10 through the flow passage 9 of the toilet body 2 and into the recessed hole 4, and cleans the toilet bowl and removes dirt from the toilet bowl. Will be eliminated. The water taken from the tank 3 into the toilet body 2 overflows from the flow path 9, but the water level does not reach the exhaust pipe 21, and the water does not flow in the exhaust pipe 21.

[0021]

According to the present invention, an air flow is generated from the water inlet of the toilet body to the water inlet in the direction opposite to the flow of water, so that it is possible to exhaust using the existing water flow path. it can. Further, since an air flow can be generated during defecation, the deodorizing effect is high. Further, since the exhaust air is discharged from a location above the water level around the intake port at the time of intake, water does not flow into the exhaust pipe.

In the present invention, when the exhaust pipe is connected to the sealing member between the toilet body and the water tank,
Since it is not necessary to perform processing such as punching holes for exhaust on the toilet body, it can be easily attached to an existing toilet bowl.

Further, in the present invention, when the opening of the overflow pipe connected to the water intake pipe is closed by the float valve, it is possible to prevent the air flow containing odor from flowing into the water tank and further into the room to enhance the deodorizing effect. it can.
