Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a deodorizing device for a flush toilet which is designed to deodorize an odor generated by defecation.

<< Prior Art >> As a deodorizing device that has been known so far, there is a type that is directly attached to a toilet bowl. This includes a device that sucks odor from an overflow pipe,
Some have a separate odor collection port.

However, when the above device is used, the odor may rise from the user's crotch area due to the posture of the person during defecation, and the person's nose may stick to the person's nose, and satisfactory results have not been obtained.

Therefore, in order to improve the effect of collecting odors, there is also known a device that generates an air flow in the toilet bowl and uses the flow of this air flow. (Refer to Japanese Utility Model Laid-Open No. 63-176172) However, this device does not have a deodorizing mechanism and requires a plurality of blower fans such as a blower fan and a suction fan, and further, an exhaust duct outside the toilet room. Must be installed, the mechanism becomes complicated, and moreover, the odor is emitted to the outside.

Furthermore, even if the deodorization mechanism is equipped, the adsorption type is adopted, so that the deodorizing ability is not sufficient not only in the long term but also in the short term. A method of masking with an agent is used.

However, in the method by masking, the bad odor caused by defecation and the odor caused by the fragrance are mixed, which may cause an unpleasant odor.On the other hand, when the odor of the fragrance is attached to clothes, etc. There are many cases where the smell is felt, and there are not a few people who dislike the transfer of scent to clothes or the like.

Therefore, in view of the above problems, the present applicant not only collects the odor at the time of defecation in the toilet by forming an air flow in the toilet, but also decomposes and deodorizes the malodorous components by using ozone. By doing so, we separately proposed a deodorizing device for a flush toilet, which not only diffuses the odor into the toilet room but also prevents the odor from being emitted to the outside.

<Problems to be solved by the invention> The present invention relates to the improvement of the above deodorizing device, in which a suction passage and a blow-out passage are formed in a device storage portion and a toilet seat on the upper part of the toilet body, and At the time of use, by opening the air outlet and the air inlet in the equipment storage part and the toilet seat so that the two passages are in communication with each other, the above-mentioned items can be used when the urine stands up and when cleaning. Its purpose is to prevent entry of urine, cleaning water and the like from the outlet and the inlet into the equipment housing and the inside of the toilet seat.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention sucks air and odor in the toilet body into the device housing and the toilet seat in the upper portion of the toilet body, and blows this out into the toilet body. A suction passage and an outlet passage for forming a suction passage, and a fan for sucking and discharging air and odors, an ozone generating portion for decomposing and deodorizing a bad odor, a decomposition of excess ozone, acceleration of ozone reaction, residual odor in the suction passage. Each of the catalysts having a function of adsorbing components is provided, and the air outlet of the suction passage is opened downward, while the toilet seat inlet of the discharge passage is upward and vertically opposed to the outlet. A deodorizing device for a flush toilet which is opened so that the outlet and the seat suction port are arranged so that they can communicate with each other and be separated from each other by the inverted rotation of the toilet seat. It is the one we are trying to provide.

<Action> When the toilet seat is laid down on the toilet body during defecation, the toilet seat suction port faces the blowout port and becomes a connected state.
The suction passage of the equipment storage part and the outlet passage of the toilet seat are in communication.

In this state, when the user sits down on the toilet seat and starts the fan, the odor generated during defecation is sucked into the suction passage by the fan together with the air inside the toilet body from the suction port of the equipment storage section immediately below the user. And is introduced into the ozone generator.

Therefore, the strong oxidative effect of ozone generated in the ozone generating section decomposes and deodorizes the malodorous components.

Next, the catalyst accelerates the decomposition action of the malodorous component of ozone, decomposes excess ozone, and adsorbs the residual odor component.

The deodorized air is sent from the air outlet and the toilet seat suction port to the air outlet passage of the toilet seat, and passes through the air outlet passage,
The air is blown out from the outlet to the inside of the toilet body and to the suction port side of the suction passage, whereby an air curtain is created in a substantially horizontal state in the toilet body by the flow of air.

Therefore, most of the odor in the toilet body is collected without leaking to the outside and is sucked into the suction passage through the suction port.

As the deodorizing action is continuously performed as described above, the odor is not diffused in the toilet room, and the discomfort caused by the odor of the operator and the residual odor of the previous user to the person who uses it later No more discomfort.

When the toilet seat is erected, the toilet seat inlet is moved away from the outlet on the side of the equipment storage, and the communication state between the outlet and the inlet is blocked.

In this state, the outlet on the side of the equipment storage portion is opened downward, and the toilet seat inlet is located in the front part of the outlet and opens rearward, so that the toilet seat stands upright. When cleaning urine or a toilet bowl, urine, cleaning water, etc. will not enter the outlet and the toilet seat suction port.
