Description

[Detailed description of the device] [Industrial applications]

The present invention is provided with a plurality of toilet bowls, and in a deodorizing structure of a toilet bowl in which an exhaust passage for deodorizing formed in each toilet bowl is joined to a collective exhaust pipe, an equalizing exhaust air volume for deodorizing each toilet bowl is provided. Regarding improvement.

[Prior art]

A conventional urinal 1 having a deodorizing function is shown in FIG. 8 (A).
As shown in (B), the left and right exhaust ports 2a facing the left and right odor collecting spaces 4 (only the right side is shown in the drawing) communicating with the urination space 3 are opened above the rear surface of the toilet body 2 to provide an exhaust passage for deodorization. Has been formed. The exhaust port 2a is an external collective exhaust pipe (not shown)
Connected to. Further, as shown in FIGS. 9 (A) and 9 (B), the toilet bowl 6 having a deodorizing function has a vent passage 9 and an exhaust port 7a communicating with the toilet space 8 behind the toilet body 7. . The exhaust port 7a is connected to an external collective exhaust pipe (not shown). By the way, in a public toilet, a plurality of the above-mentioned urinals 1 and urinals 6 are arranged, the exhaust port 2a of each urinal 1 is connected to the collective exhaust pipe of the urinal, and the exhaust ports of each urinal 6 are connected.
7a is connected to the common exhaust pipe for the toilet. Although illustration is omitted, the odor sucked into each collecting exhaust pipe is discharged to the outside by an exhaust fan connected to the collecting exhaust pipe. In addition,
The collective exhaust pipe for urinals and the collective exhaust pipe for urinals are connected to an exhaust fan dedicated to each collective exhaust pipe or a common exhaust fan.

[Problems to be solved by the device]

In the collecting exhaust pipe, the suction pressure in the portion near the exhaust fan is generally higher than the suction pressure in the portion far from the exhaust fan. Therefore, regarding the deodorizing ability of the plurality of urinals 1 connected to one collective exhaust pipe, the urinal 1 near the exhaust fan has an excessive capacity, and the urinal 1 far from the exhaust fan has an insufficient capacity. Such uneven deodorizing ability
It also occurs in a plurality of toilet bowls 6. It is an object of the present invention to provide a deodorizing structure for a toilet bowl, which can equalize the deodorizing exhaust air volume of a plurality of toilet bowls in order to solve the uneven deodorizing ability.

[Means for Solving the Problems]

The first means adopted by the present invention comprises a plurality of toilet bowls,
In the deodorizing structure of the toilet in which the deodorizing exhaust passage formed in each toilet is joined to the collective exhaust pipe, the air flow rate adjusting damper is arranged in the exhaust passage of each toilet. The second means adopted by the present invention comprises a plurality of toilet bowls,
In the deodorizing structure of the toilet in which the deodorizing exhaust passage formed in each toilet is joined to the collective exhaust pipe, the suction port area adjuster is arranged on the suction side of the exhaust passage of each toilet. The suction port area adjuster is provided with a plurality of releasable piece portions partitioned by notch grooves so as to block a part of the suction port of the exhaust passage of the toilet bowl, and cuts any releasable piece portion. In some cases, the opening area of the suction port can be increased by cutting and removing the groove.

[Action]

In the first means, the amount of exhaust air that passes through the exhaust passage of each toilet and is sucked into the collective exhaust pipe is proportional to the opening / closing degree of the air volume adjusting damper arranged in the exhaust passage of each toilet. Therefore, by appropriately adjusting the opening / closing degree of each air volume adjusting damper, the exhaust air volume of each toilet can be made constant and the deodorizing ability of all toilets can be made uniform. In the second means, the amount of exhaust air that passes through the exhaust passage of each toilet and is sucked into the collective exhaust pipe is opened by the suction port area adjuster arranged on the suction port side of the exhaust passage of each toilet. Proportional to the suction port area. Therefore, by appropriately adjusting the suction port area for each suction port area adjuster, the exhaust air volume of each toilet can be made constant and the deodorizing ability of all toilets can be made uniform.

【Example】

Hereinafter, a deodorizing structure of a toilet bowl according to the present invention (hereinafter, referred to as “main structure”) will be described based on an embodiment shown in the drawings. (First Embodiment) FIG. 1 shows an essential part of a first embodiment in which the structure 10 of the present invention is applied to a urinal 11. In each urinal 11 provided in the toilet, an odor outlet 2a penetrating the urinal body 2 and a damper 13 disposed on the connection side step 2b form an urinal side exhaust passage 12. There is. The exhaust passage 12 is connected to a collective exhaust pipe 15 via a packing 14. The damper 13 has an annular frame plate 16 as shown in FIG.
A disk-shaped blade 17 is rotatably attached to the blade, and the blade 17 can be forcibly rotated to adjust the rotation angle.
