For example, Japanese Unexamined Utility Model Publication No. 60-80169 has been disclosed as a device for discharging the odor remaining in the toilet bowl to the outside. In this method, an exhaust passage is formed between the toilet bowl and the back, and the odor of the toilet bowl is discharged from the exhaust passage to the outside. An exhaust pipe is connected to the end of the exhaust path, and a suction fan or the like is provided downstream of the exhaust pipe to forcibly exhaust the odor in the toilet bowl so that the user does not feel uncomfortable. .

Further, in order to improve the appearance, it is preferable that the exhaust pipe and the like be not exposed to the outside, and the connection between the exhaust path provided in the toilet body and the exhaust pipe provided in the wall or panel is exhausted. Open the passage to the back of the toilet and open the end of the exhaust pipe almost flush with the surface of the wall or panel, so that the opening of the exhaust passage of the toilet and the exhaust pipe abut against each other, There is an elastic sealant that is configured to maintain the security of the abutting opening, so that the exhaust pipe and the connecting portion are not visible from the outside.

(C) Problems to be Solved by the Invention However, the gap between the wall or the panel and the back surface of the toilet body must be narrower than the gap that the elastic sealant can effectively seal. Alternatively, the flatness of the back of the toilet body with the panel and the installation accuracy of the toilet body must be increased, which causes a problem that the cost is increased, and the toilet body is damaged, and the toilet body is replaced. In this case, since the non-drying elastic sealant adheres the wall body to the toilet, it is difficult to remove the toilet body, which takes time and effort, and also removes the sealant from the wall body after removing the toilet body. However, there is a drawback in that a work for scraping this is required.

(D) Means for Solving the Problems According to the present invention, an exhaust path is provided inside a toilet body provided in a toilet room, a suction port of the exhaust path is opened inside the toilet bowl, and a discharge port of the exhaust path is provided. The exhaust port is provided on a partition wall that separates the exhaust path from the outside, and the exhaust port is communicatively connected to a toilet-side opening of an exhaust pipe provided on a wall or a panel via a sealing member. The base end of the seal body made of an elastic material reinforced by a reinforcing member is attached to the section, the distal end of the seal body extends toward the partition wall provided with the discharge port, and the extended end face elastically contacts the partition wall. A connecting structure for a deodorizing exhaust pipe in a flush toilet characterized by being configured in contact with the toilet.

The present invention is also characterized in that, in the connection structure of the deodorizing exhaust pipe described above, a peripheral groove is provided on a contact surface of the seal member facing the partition wall.

According to the present invention, an exhaust passage is provided inside a toilet body provided in a toilet room, a suction opening of the exhaust passage is opened inside the toilet bowl, and a discharge opening of the exhaust passage separates the exhaust passage from the outside. An elastic member provided on the partition wall, the discharge port being connected to a toilet-side opening of an exhaust pipe provided on a wall or a panel through a seal member, and the seal member being reinforced by a reinforcing member at the discharge port of the exhaust path. A flushing body comprising: a sealing body comprising a sealing body, the sealing body protruding toward a wall surface or a panel, and a protruding end surface elastically abutting against a corresponding surface of a wall surface or a panel forming an outer periphery of the exhaust pipe. It is an object of the present invention to provide a connection structure of a deodorizing exhaust pipe in a toilet.

(E) Function / Effect According to the present invention, the odor of the excrement in the toilet bowl is sucked into the exhaust path communicating with the inside of the toilet bowl, and is discharged from the exhaust pipe through the wall to the outside of the toilet room. Thus, it is possible to prevent the user from feeling unpleasant due to the bad smell.

In the present invention, the exhaust port of the exhaust passage provided inside the toilet body and the exhaust pipe provided on the wall surface or the panel communicate with each other through a seal body made of an elastic material reinforced by a reinforcing member. Therefore, even if there is a large gap between the toilet body and the wall or panel, it is possible to prevent odor from leaking from the connection portion, and the flatness of the back surface of the toilet body with the wall or panel and the installation accuracy of the toilet body are reduced.
