Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toilet device of a so-called push-up type toilet that eliminates odor leakage from the lid of the toilet tank and is useful for environmental conservation of houses.

[Conventional technology]

In areas where sewerage and sewage facilities are insufficient,
A scoop-type toilet device is used, which stores the feces in a fecal tank. Furthermore, in many of these toilet devices, the toilet bowl and the toilet tank are connected using a defecation pipe, and the toilet tank is installed outdoors or inside an outdoor shed. Furthermore, the defecation pipe is of a push-up type in which the defecation is pushed up and flows out into the faeces tank by forming an upwardly facing part inside the faeces tank.
It is also practiced to trap feces inside the defecation pipe to prevent odors from flowing back from the toilet tank to the toilet bowl. In addition, in this type of toilet, an odor removal tube is often provided below the toilet bowl to exhaust the odor from the toilet to the outside.

On the other hand, in the conventional toilet device, the toilet tank is buried underground with its upper end aligned with the base concrete, as shown schematically in FIG. 9, and a valve seat B surrounding the opening of the toilet tank A is fixed. Moreover, the lid C is attached to the valve seat B to seal it, and the inside of the toilet tank A is not intended to be ventilated at all.

[Problem that the invention attempts to solve]

In conventional toilet devices of this type, the internal pressure of the toilet tank A increases as defecation from the upright portion rises, and even though the lid body C is relatively heavy, odor is emitted. easily leaks from the periphery of the lid C, thus contaminating the air around the toilet tank A and impeding the livability of the house. Particularly when the toilet tank A is located near the entrance of the house, such odor also reduces the value of the house.

In addition, each time the lid C is scooped out, dirt, dust, etc. accumulate in the groove D into which the lid C fits, impairing the airtightness and increasing the leakage of odors.
Another drawback is that small worms can enter the toilet tank and produce larvae such as maggots and pink worms.

There is also the problem that the increase in internal pressure obstructs the flow of feces from the defecation pipe and causes the feces to rise below the toilet bowl. Furthermore, leakage of ammonia gas, etc. that stays inside corrodes the lid C, and along with the corrosion, the catch B, and furthermore the catch B.
There are drawbacks such as damaging the supporting mortar GE.

The present invention is based on the idea of communicating the upper part of the toilet tank with the odor removal cylinder provided below the toilet bowl, and this toilet can solve the above-mentioned problems by exhausting the odor inside the toilet tank and helping to dry the inside. The purpose is to provide equipment.
