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 the 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 blowing 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 adheres 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.

In view of the above difficulties, the present applicant not only deodorizes the odor during 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 an improvement of the above deodorizing device, in which a suction passage and a blow-out passage are formed in the device storage section and the toilet seat at the upper part of the toilet body, and At the time of use, each opening is provided facing the equipment storage part and the toilet seat so that the two passages are in communication with each other, and the opening / closing lid attached to each opening is closed when the toilet seat stands up. The purpose is to attach them so that they can operate, and thereby prevent urine, cleaning water, etc. from entering the equipment storage part or the toilet seat during urine or cleaning. is there.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention inhales air and odor in the toilet body into the device storage portion and the toilet seat in the upper portion of the toilet body, and blows them out into the toilet body. A suction passage and a blow-out passage for forming a suction passage and a fan for sucking and exhausting air and odor in the suction passage, and decomposing a foul odor,
An ozone generating section for deodorization and a catalyst having functions of decomposing excess ozone, promoting ozone reaction, adsorbing residual odor components, etc. are arranged respectively, and the equipment storage section and the toilet seat are connected to the suction passage and the discharge passage. Opposite each opening, and attached to the opening of the equipment housing is an opening / closing lid that is biased in the closing direction by a spring and that is opened by the projection of the toilet seat against the spring force when using the toilet seat. On the other hand, an object of the present invention is to provide a deodorizing device for a flush toilet in which an opening / closing lid that is opened by the air pressure sent by the fan and that is closed by its own weight when the toilet seat stands up is attached to the opening of the toilet seat.

<Operation> When the toilet seat is laid down on the toilet body during defecation, the projection of the toilet seat pushes up the open / close lid in the opening of the device storage portion against the spring force, and the opening is opened.

At this time, the open / close lid at the opening of the toilet seat is in a hanging state due to its own weight, and the opening is closed.

When the user sits on the toilet seat in this state and starts the fan, the odor generated during defecation is sucked into the suction passage by the fan from the suction port in the vicinity immediately below the user, and is introduced into the ozone generation unit. .

Therefore, the bad odor component is decomposed and deodorized by the strong oxidizing action of ozone generated in the ozone generation section.

Further, 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 suction passage through the opening to the opening of the toilet seat, so the opening / closing lid of the opening is opened by the pressure sent by the fan, and the opening is opened to deodorize. The air concerned later passes through the blow-out passage, is blown out from the blow-out port, further passes through the inside of the toilet body and is sucked in from the inlet side, whereby an air curtain due to the flow of air is created in the toilet body.

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.

By continuously performing the deodorizing action as described above, the odor is not diffused into the toilet room, and the discomfort caused by the odor of the person concerned and the residual odor given to the user later can be eliminated. .

When the toilet seat is erected after toilet, the opening / closing lid is closed by the biasing force of the spring due to the release of the pressing force by the protrusion of the toilet seat, and the opening of the equipment storage portion is closed.

On the other hand, the opening / closing lid on the toilet seat side is rotated by its own weight, and its opening is also closed.

Therefore, it is possible to prevent urine, cleaning water, and the like from entering the equipment storage portion and the inside of the toilet seat during urine or cleaning.
