Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has the functions of deodorizing, cleaning, ventilation, and draining excess water by using the washing water discharge hole 8 and the excess water drain pipe 1 for exhaust.

This relates to a completely deodorizing flush toilet.

Traditionally, flush toilets have been ventilated using an indoor ventilation fan 4'.
It was done at However, this takes a long time to ventilate as the odor spreads throughout the room. This odor not only makes the person using the product unpleasant, but also the person who uses it subsequently. Stagnant odors can stain clothing and carry the odor with you.
Also, when the door is opened or closed, the odor leaks out into other rooms. Furthermore, in the winter, the odor cannot be removed simply by turning on the indoor ventilation fan 4', and there is a drawback that the odor is blown out from between the vents and into other rooms. Deodorization methods using fragrances and chemicals have been used, but all of them have only superficial effects, and no fundamental solution to complete deodorization has been achieved.

This invention was made in order to solve the above-mentioned drawbacks and meet the strong demands of users over a long period of time.The structure is explained with reference to the drawings as follows: (a) Excess water drain pipe in the water tank 5 At the top tip of 1, T
The shaped pipe 11, the 90-degree bent pipe 12, and the straight pipe 13 are directly connected, taken out to the outside of the water tank 5, and connected to the exhaust pipe 2.

(b) Connect one end of the 90 degree bent pipe 14 and the surplus water drainage sub pipe 3 to the other end of the T-shaped pipe 11, and connect the other end of the surplus water drainage sub pipe 3 to the water tank 5 with the other end facing toward the bottom of the water tank 5. It is located below the lowest water level 10 within the area.

(c) Connect the tip of the exhaust pipe 2 to a deodorizing fan 4 or a ventilation fan 4'.
Directly connected to.

Since this invention has the above structure, the toilet main body 7
Since the tip of the surplus water drainage auxiliary pipe 3 is opened below the lowest water surface level 10, the odor generated inside the auxiliary pipe 3 will be removed from the cleaning water outlet 8 no matter where the water surface level is. The excess water is inhaled, passes through the surplus water drain pipe 1, passes through the exhaust pipe 2, and is promptly discharged by the deodorizing fan 4 or the ventilation fan 4'. The wash water outlet hole 8 is closed for about 5 seconds while the wash water is flowing out from the wash water outlet hole 8 due to the water flow, but even if you use the toilet during washing, the wash water and dirt/odor will not flow out. According to the results of experiments, it is completely impossible for odor to leak outside from the toilet main body 4. When the cleaning is finished, the cleaning water discharge hole 8 is opened and the exhaust is repeated again. By providing the surplus water drainage auxiliary pipe 3 opened below the lowest water level 10, the drainage hole 8, the drain pipe 16, the surplus water drainage pipe 1, the exhaust pipe 2, and the deodorizing fan 4 or ventilation fan 4' can be connected to each other. Since it is possible to connect directly, suction can be performed directly without going through the space inside the aquarium, so there is no need to make the lid of the aquarium 5 airtight, and it is possible to quickly and reliably suction and exhaust with a weak airflow. It is. In the conventional exhaust method, the odor generated inside the toilet bowl body 7 was raised throughout the room and exhausted by the ventilation fan 4' or natural ventilation. Since the structure is such that water is taken in and exhausted from the water discharge hole 8, outdoor air flows into the toilet main body 7 along with indoor air, mixes with odor, passes through the excess water drain pipe 1, and then goes to the exhaust pipe 2 and the deodorizing fan. Since the air is exhausted to the outside through the ventilation fan 4 or the ventilation fan 4', fresh air always flows through the indoor space of the toilet, making it comfortable. In addition, if the water surface rises above the normal water level 9 due to a failure of the water supply valve 6, surplus water flows into the surplus water drainage subpipe 3, passes through the surplus water drainage pipe 1, and is discharged to the drain pipe 16. Therefore, it is safe because the water surface will not rise above the highest water surface level 15.

Due to the above structure and function, the deodorizing device is extremely easy to manufacture and install, and has a complete deodorizing function, so it is considered to be highly economical and practical.
