There is something set up. Then, the odor generated inside the toilet main body during or after defecating is removed to the outside through the exhaust passage, thereby deodorizing the toilet 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 body, taking into account the ease of piping work and appearance. .

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

In particular, no consideration is given to where the high concentration of odor is coming from within the toilet bowl, so if the location where the high concentration of odor is generated 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.

In addition, if the suction power in the exhaust passage is increased, it is possible to suck out the odor generated inside the toilet body, but in this case, the exhaust fan will become larger and cause noise, and the exhaust passage from inside the toilet body will be increased. It is conceivable that the user will feel the airflow flowing toward the user, causing discomfort to the user.

An object of the present invention is to provide a flush toilet having a deodorizing function that can solve the above problems.

(d) Means for Solving Problems The present invention provides an annular rim passageway that connects to a washing water source attached to the rear of the toilet bowl body around the entire upper end of the toilet bowl body. A plurality of water outlets were provided on the bottom wall of the toilet bowl to discharge washing water in the direction of the toilet bowl.

In the flush toilet, an odor suction nozzle body for sucking odor is arranged in the toilet bowl so as to be movable back and forth, and
This invention relates to a flush toilet having a deodorizing ability, which is configured to move the odor suction nozzle body to a fixed position forward by appropriate means when sitting on the toilet seat.

Further, the present invention is characterized in that the seating on the toilet seat is detected by the seating detection means, and the detection output is used to drive the nozzle drive means to move the odor suction nozzle body forward to a fixed position. have
