[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deodorizing Western-style toilet having a function of discharging the odor in a toilet bowl, and particularly to a deodorizing Western-style toilet configured to discharge the odor to the secondary side of the trap of the Western-style toilet.

[0002]

[Prior art]

 A conventional example of a deodorizing type Western-style toilet bowl in which odor-containing air in the toilet bowl is sent to the secondary side of the trap of the Western-style toilet bowl to deodorize will be described with reference to FIG. The Western-style toilet according to this conventional example has an S-shaped trap.

A rim water passage 3 is provided at the upper edge of the toilet bowl 2 of the Western-style toilet 1. The toilet bowl 2 is in communication with a drain pipe 7 via a trap 4 and a drain socket 5. A deodorant suction port 8 is provided on the inner side of the upper edge of the toilet bowl 2 (at the base of the shower toilet nozzle). The deodorizing suction port 8 is connected to a hose connecting portion 13 of the drain socket 5 via an intake duct 9, a deodorizing fan 10, a check valve 11 and an exhaust hose 12.

The hose connecting portion 13 projects to the rear surface of the western-style toilet bowl 1 through an opening 14 provided in the rear surface of the western-style toilet bowl 1. A pressure sensor 15 is attached to the opening of the peripheral wall of the exhaust hose 12 immediately downstream of the check valve 11. The pressure sensor 15 is a sensor for controlling the operation of the deodorizing fan 10 and the check valve 11, and when the pressure equal to or higher than a set value is detected, the deodorizing fan 10 is stopped and the check valve 11 is closed.

【Example】

 FIG. 1 shows an embodiment of a Western-style toilet 1A having an underfloor drainage type S trap, in which a deodorizing pipe (exhaust hose 12) connection port 16 is provided on the rear surface of the Western-style toilet 1A made of ceramics. There is. The connection port 16 is provided so as to communicate with the secondary side of the trap 4A via a passage 18. The exhaust hose 12 is connected to this connection port 16 via a socket 17.

The drain socket 5 A has a structure in which the hose connecting portion 13 is removed from the drain socket 5.

Other configurations are the same as those of the conventional example shown in FIG. 2, and the same portions are denoted by the same reference numerals and the description thereof is omitted.

The deodorizing Western-style toilet 1A configured as described above can be constructed using the drain socket 5A of a normal shape having no hose connection portion. Further, an opening (opening 14 in FIG. 2) for passing the hose connection portion is not required, and quality control and process control for positioning this opening with high accuracy are not required.

Since the cover wall 18 facing the deodorizing pipe connection port 16 is provided so as to smoothly continue to the inner surface of the trap, the water passage resistance in the trap 4A is small. Moreover, the siphon forming action in the trap 4A is not hindered.

FIG. 3 is a sectional view showing an embodiment of a Western-style toilet 21 having a P-type trap of floor drainage type. A rim water passage 23 is provided on the upper edge of the toilet bowl 22 of the Western-style toilet 21. The bottom of the toilet bowl 22 is connected to a drain pipe 25 via a P-type trap 24.

A low tank 26 is provided on the back side of the upper part of the Western-style toilet 21, and washing water is supplied to the rim water passage 23 through the float valve device 27 and the water passage 28. An intake duct 30 is surrounded by an overflow pipe 29 provided upright on the float valve device 27. The intake duct 30 is connected to the intake side of the deodorizing fan 31. A backflow prevention valve 32 and a wind pressure switch 33 are provided on the exhaust side of the deodorizing fan 21, and an exhaust hose 34 is further connected.
