[Problems to be solved by the device]

 According to the conventional toilet bowl with the deodorizing device, the odor in the ball portion is deodorized by the ozone deodorizing device and exhausted into the room.Therefore, large-scale work such as installing piping for discharging the odor inside and outside the toilet room is required. It is possible to deodorize the inside of the ball portion with an extremely simple structure without needing to do so.

However, since the outlet side of the exhaust fan is opened so as to face the inside of the room, that outlet directly comes into view and becomes a negative factor in terms of improving the aesthetics of the toilet room, and it also leaves a residue when ozone is deodorized. There is a problem that ozone is discharged directly into the room and goes to the nose of the user, and when a strong odor that cannot be deodorized with the initially set amount of ozone is generated, it is exhausted without complete deodorization. However, there was room for improvement. The present invention has been made in view of the above-mentioned conventional circumstances, and the purpose thereof is to make the outlet side of the above-mentioned forced exhaust deodorization section face the inside of the toilet body, and To solve the problem.

[0005]

Means for Solving the Problems In order to achieve the above object, a toilet bowl with a deodorizing device of the present invention has a odor suction passage connected to an upper part of a rear portion of a toilet body having an odor suction passage facing a ball portion. A forced exhaust deodorizing unit having an exhaust fan and a deodorizing device arranged upstream or downstream of the fan is provided, and a blow-off side of the exhaust fan is provided with a cleaning water supply passage to the ball unit. It is characterized by contacting. In addition, in the above toilet, a flush water tank is installed above the rear part of the toilet body, and a drainage device provided in the flush water tank is connected to the running water channel of the toilet body to form a flush water supply path to the bowl portion. However, a forced exhaust deodorizing section is provided in the wash water tank, and the blow-out side of the exhaust fan of the forced exhaust deodorizing section is connected to the running water channel via a connecting pipe standing in the wash water tank. You may.

Further, the outlet side of the exhaust fan may be connected to the running water channel via an overflow pipe that is connected to the drainage device and rises in the wash water tank. Furthermore, in the above toilet bowl, a water supply pipe equipped with a flush valve in the middle is connected to the running water channel of the toilet body to form a wash water supply route to the ball section, and the outlet side of the exhaust fan of the forced exhaust deodorization section is connected to the outlet side. Alternatively, the water supply pipe may be connected to the downstream side of the flush valve.

[0007]

[Action]

 According to the above configuration, since the outlet side of the exhaust fan is not exposed to the room, it does not become a negative factor in improving the aesthetics in the toilet room. In addition, the odor in the ball part is sucked into the odor suction passage, deodorized by the deodorizing device, then discharged into the ball part through the wash water supply route, and then sucked into the odor suction passage again. Even if it is, it can be deodorized repeatedly with a deodorizing device, and more complete deodorization becomes possible. Furthermore, even if an ozone deodorizing device is used as the deodorizing device, residual ozone components, incomplete deodorizing odors, etc. are not directly discharged into the room. In addition, the residual ozone component can deodorize and sterilize the inside of the wash water supply route. Further, the exhaust air into the ball portion breaks the water film in the wash water discharge hole that opens at the end of the wash water supply path so as to face the ball portion, and prevents the water film from freezing in cold regions.

It is sucked into the suction passage 5.

[Effect of the device]

 Since the toilet bowl with the deodorizing device of the present invention is configured as described above, there is no fear that the bleeding side of the exhaust fan is directly exposed to the room, which may cause a decrease in aesthetics, and the odor that has not been completely deodorized remains. In the case of ozone deodorization, there is no fear that residual ozone components will be exhausted directly into the room, enabling more comfortable use. Further, even a strong odor that cannot be deodorized with the initially set amount of deodorizing components in the deodorizing device is repeatedly deodorized by the deodorizing device, so more complete deodorization can be realized. In the case of ozone deodorization, the residual ozone component is used to deodorize and sterilize the inside of the cleaning water supply route, and the exhaust air into the ball section is made as clean as possible. Furthermore, it has many effects such as preventing the washing water discharge hole from freezing by the exhaust air into the ball part, and saving the time and effort of separately molding the toilet bowl body with a large diameter discharge hole. ..
