Description

TECHNICAL FIELD The present invention relates to a simple flush toilet bowl 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] The drain pipe is connected to a septic tank, and the exhaust pipe is connected to the septic tank. Therefore, even in the conventional simple flush toilet, the drain 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 Problem] A simple flush toilet provided with a deodorizing device of the present invention is a toilet bowl provided with a drain port that opens downward at the lower end and a rim water passage around the upper part. A device for supplying washing water to the rim water passage, a cylindrical cartridge connected to the drain, a closed posture that is disposed in the cartridge and covers the drain from below, and the drain The flapper rotatably supported by the cartridge so as to be able to assume an open position in which the container is opened and the rear part of the toilet are drawn around, and the inside of the toilet bowl and the inside of the cartridge are communicated so as to be ventilated. An exhaust passage, a check valve provided in the exhaust passage that allows an air flow only in the direction from the toilet bowl to the cartridge, and a deodorizing fan that blows air toward the cartridge provided in the exhaust passage. With a deodorizing device provided Is.

[Operation] With 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.

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 exhaust port of the deodorizing fan 38, and the check valve 40 is provided with a duct 42.
Is connected to the branch pipe 46 of the cartridge 44 via.

The cartridge 44 includes a tubular portion 48 that extends in the vertical direction so as to surround the drainage port 14, the branch pipe 46 that extends laterally from the tubular portion 48, and a lower end of the tubular portion 48. A pedestal portion 50 integrally provided with the shaft, a flapper 56 pivotally supported by the tubular portion 48 via a shaft 52 and a lever 54, an arm 58 integral with the shaft 52, and a balancer 60 fixed to the arm 58. It has and. In addition,
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 the lower side to close the drainage port 14. An interlocking device (not shown) for rotating the arm 58 upward is connected to the arm 58, and the flapper 56 is forcibly rotated downward by operating the interlocking device. It is possible to open the drainage port 14 by means of this. 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.

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.

FIG. 2 is a vertical sectional view of a simple flush toilet with a deodorizing device according to another embodiment of the present invention.

In this embodiment, a duct 24a is provided upright on the float valve device 24, and the duct 24a is raised above the upper end of the overflow pipe 64 of the low tank 20.
In this embodiment, the deodorizing fan 38 is installed in the raw tank 20, and the suction port of the deodorizing fan 38 is connected to the duct 24a via a short duct 66. This deodorant fan 3
A check valve 40 is provided at the exhaust port of 8, and the exhaust side of the check valve 40 is connected to a branch pipe 46 of a cartridge 44 via a duct 42.

The other structure of the simple flush toilet of FIG. 2 is the same as that of FIG. 1, and the same portions are denoted by the same reference numerals and the description thereof is omitted.

Also in the present embodiment, by operating the deodorizing fan 38, the air containing the odor in the toilet bowl 12, the rim water passage 16,
Water supply channel 18, ducts 24a, 66, deodorizing fan 38, check valve 40,
It can be forcibly discharged to the drain pipe via the duct 42, the branch pipe 46 and the cartridge 44. In this example,
Since the deodorizing fan 38 is installed in the low tank 20, there are few exposed structures around the toilet bowl, and it is easy to clean and good in appearance.

[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 to the drain pipe through the cartridge. It is possible to reliably prevent the odor from spreading. In the present invention, since the exhaust passage is routed around the rear part of the toilet bowl to communicate the inside of the toilet bowl with the cartridge, it is not necessary to provide a pipe for odor discharge on the wall or floor of the toilet room, and the construction can be performed. It's easy.
