Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a flush toilet having a deodorizing mechanism using a toilet seat.

(b) Conventional technology Conventionally, as a form of flush toilet with a deodorizing function, an exhaust passage was provided in the toilet bowl as described in Japanese Utility Model Application Publication No. 57-60981 and Japanese Patent Application Publication No. 60-33590. There is something set up. Then, the odor generated in the toilet bowl during or after using the toilet is removed to the outside through the exhaust passage, thereby deodorizing the user and eliminating the user's discomfort caused by the odor.

(c) Problems to be Solved by the Invention However, in the above-mentioned conventional flush toilets, the exhaust passage is connected and attached exclusively to the rear of the toilet bowl, taking into account the ease of piping work, appearance, etc.

Therefore, even if the odor generated at the rear of the toilet bowl can be effectively sucked and exhausted, the odor generated at other parts of the toilet bowl, such as the front, left and right sides, or the center, cannot be effectively sucked and exhausted. I couldn't.

In particular, no consideration is given to where in the toilet bowl the highly concentrated odor is coming from, so if the location where the highly concentrated odor is not located at the rear of the toilet bowl, there will be little odor suction effect. That is, it was not possible to improve the deodorizing effect.

Therefore, in order to suction the odor over a wide range, it is preferable to provide a deodorizing port near the top opening of the toilet bowl.
It is conceivable to provide a deodorizing port in the rim waterway or in the toilet seat.

In this case, rather than providing a deodorizing hole in the rim passageway,
Providing a deodorizing port on the toilet seat near the defecation position has better deodorizing efficiency, but when used for men's urination, the problem is that the toilet seat is in an upright position, which almost eliminates the deodorizing effect.

Further, as described above, it is not possible to achieve the optimum deodorizing effect simply by providing deodorizing holes in the rim passageway.

(d) Means for Solving the Problems In the present invention, in a flush toilet having a toilet seat that can be raised and lowered, the odor inside the toilet bowl is deodorized through a deodorizing port provided on the toilet seat when the toilet seat is in a reclined state, and when the toilet seat is in an upright state. Now, there is a deodorizing mechanism using a toilet seat, which is configured to deodorize the inside of the toilet bowl through a deodorizing port provided near the rim of the toilet bowl, and is configured to switch the optimal deodorizing port according to the up-and-down movement of the toilet seat. The purpose is to provide a flush toilet with a

(e) Action/effect According to the present invention, the following effects are produced.

■ When the toilet seat is reclined while sitting on the toilet seat, the odor inside the toilet bowl can be deodorized through the deodorizing port installed on the toilet seat. Deodorization can be performed more efficiently.

Moreover, if an annular sealing elastic body or the like is interposed between the lower circumferential surface of the toilet seat and the upper circumferential surface of the toilet bowl, the odor inside the toilet bowl can be removed between the lower circumferential surface of the toilet seat and the upper circumferential surface of the toilet bowl. It is possible to completely deodorize without leaking to the outside through the gap formed between the two.

■When the toilet seat is in the upright position when used for men's urination,
Since the odor inside the toilet bowl can be deodorized through the deodorizing port provided on the rim of the toilet bowl, deodorization can be carried out efficiently even in such a case.

At this time, although the deodorizing efficiency is inferior to the case where the odor is sucked through the deodorizing hole of the toilet seat, the deodorizing effect is sufficient since the use is limited to urine with little odor.

(f) Embodiment The embodiment of the present invention will be explained in detail based on the drawings, as shown in Figs.
(A) shown in Fig. 3 is a flush toilet, in which a toilet bowl (1) is placed on the floor (F) in the toilet (D), and a toilet seat (2) is placed on the top of the toilet bowl (1).
