Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a simple flush toilet provided with a deodorizing device.

[Prior Art] A simple flush toilet has a toilet bowl provided with a drain opening that opens downward at the lower end, and a rim water passage around the upper part,
It has a device for supplying washing water to the rim water passage and a flapper for closing the drainage port from the lower side. A small amount of water is stored in this toilet bowl, and a water seal is provided between the drain port and the flapper. When the flapper is opened, the waste in the toilet bowl falls by gravity into the drain pipe. Then, a very small amount of water is supplied into the toilet bowl to clean the bowl surface.

[Problems to be solved by the invention] Since the above drainage pipe is connected to the septic tank, and the exhaust pipe is connected to this septic tank, even in the conventional simple flush toilet, the drainage pipe in the downstream side of the flapper is Exhaust deodorization was possible.

However, in the conventional simple flush toilet, the odor in the toilet bowl is not forcibly discharged, which causes the odor to diffuse into the toilet room.

[Means for Solving the Problems] A simple flush toilet provided with a deodorizing device of the present invention is a toilet bowl having a drain opening that opens downward at the lower end and a rim water passage provided around the upper part. A flush water supply passage extending from the rim water passage toward the rear of the toilet, an opening for deodorizing provided at a rear end of the toilet of the water supply passage, and a flapper for closing the drain outlet from the lower side. And a tubular cartridge that incorporates the flapper and is connected to the drain outlet, a branch pipe that extends from the side surface of the cartridge toward the rear of the toilet, and the deodorizing opening and the branch pipe that communicate with each other. A vertically extending exhaust passage, a check valve provided in the exhaust passage, which allows only an air flow in a direction from the opening to the branch pipe, and a downward passage provided in the exhaust passage. And a deodorizing fan having an exhaust port.

[Operation] According to the simple flush toilet provided with the deodorizing device of the present invention, the odor in the toilet bowl can be forcibly discharged to the drain pipe. Since the exhaust passage extends vertically and the deodorizing fan provided in this exhaust passage has a downward air outlet, even if water flows into the exhaust passage from the water supply passage, this water will not be discharged by the deodorizing fan immediately. To flow out to the cartridge.

Embodiments Embodiments will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a simple flush toilet with a deodorizing device according to an embodiment of the present invention. This simple flush toilet 10 is provided with a toilet bowl 12 at the front part thereof, and a drain port 14 which opens downward at the lower end of the toilet bowl 12. A rim water passage 16 is provided at an upper part of the toilet bowl 12, and the rim water passage 16 can be supplied with washing water from a low tank 20 via a water supply passage 18.

A float valve device 24 is provided at the flush water outlet 22 of the raw tank 20. 26 indicates a float valve.
A strut 28 is erected on the float valve device 24, and a stopper 30 for preventing floating of the float valve 26 is fixed to the strut 28.

A rising portion 32 is provided on the toilet bowl rear side of the water supply channel 18, and an opening 34 is provided on the rear side of the rising portion 32. The rising portion 32 is for preventing water that has passed through the float valve device 24 and flowed into the water supply passage 18 from entering the opening 34.

Another opening 36 is provided below the opening 34, and a deodorizing fan 38 is connected to the opening 36. A check valve 40 is provided at the downward air outlet of the deodorizing fan 38, and the check valve 40 is connected to a branch pipe 46 of a cartridge 44 via a duct 42.

The cartridge 44 includes a tubular portion 48 that extends in the up-down direction so as to surround the drainage port 14, the branch pipe 46 that extends from the side surface of the tubular portion 48 to the rear of the toilet, and the tubular portion 48. A pedestal portion 50 integrally provided at the lower end of the shaft, a shaft 52 and a lever 54 on the tubular portion 48.
A flapper 56 pivotally supported via a shaft and an arm integrated with the shaft 52.
58 and a balancer 60 fixed to the arm 58. The lever 54 is also integrated with the shaft 52, and the gravity of the balancer 60 causes the flapper 56 to come into contact with the drainage port 14 from below, thereby closing the drainage port 14. In addition,
An interlocking device (not shown) for rotating the arm 58 upward is connected to the arm 58. By operating the interlocking device, the flapper 56 is forcibly rotated downward to drain water. It is possible to open the mouth 14.
Reference numeral 62 indicates packing.

In the simple flush toilet having such a structure, the flapper 56 is opened by the interlocking means, whereby the waste in the toilet bowl 12 is dropped and discharged through the cartridge 44 into the drain pipe connected therebelow. Further, by pulling up the float valve 26, a small amount of cleaning water in the low tank 20 is supplied into the toilet bowl 12 from the rim water passage 16 to clean the bowl surface of the toilet bowl 12.

Then, when the deodorizing fan 38 is operated, the air containing the odor in the toilet bowl 12 causes the rim water passage 16, the water supply passage 18, the opening 34,
36, the deodorizing fan 38, the check valve 40, the duct 42, the branch pipe 46, and the cartridge 44 are discharged to a drain pipe (not shown).
Therefore, it is possible to forcibly discharge the odor in the toilet bowl 12 and prevent the odor from diffusing into the toilet room.

When the deodorizing fan 38 is stopped, the check valve 40 is closed to block the flow of air in the reverse direction from the drain pipe toward the toilet bowl 12 and prevent odor from flowing back from the drain pipe.

Since the exhaust port of the deodorizing fan 38 is directed downward, even if water flows into the deodorizing fan 38 through the openings 34, 36, this water immediately flows out from the exhaust port, and the cartridge
It is discharged to 44.

In this embodiment, the deodorizing fan 38 and the duct 42 are a low tank.
The deodorizing fan 38 and the duct 42 are not conspicuous because they are arranged on the rear surface of the toilet bowl below 20, so that they look good. Further, since the deodorizing fan 38 is arranged outside, it is easy to install, inspect, and repair the deodorizing fan 38.

In addition, the present embodiment has an effect that the exhaust passage length from the opening 36 to the cartridge 44 is short and the pressure loss is small.

[Effects of the Invention] As described above, in the simple flush toilet of the present invention, the odor in the toilet bowl can be forcibly discharged, so the odor is surely diffused from the toilet bowl into the toilet room. Can be prevented. Further, since the deodorizing fan and the duct are arranged in the rear part of the Western-style toilet, the deodorizing fan and the duct are inconspicuous and have a good appearance. Furthermore, water from the water supply channel does not collect in the deodorizing fan, and the durability of the deodorizing fan is good.
