Description
FLUSH TOILET
Mentioned Technical Sector
The invention relates to field about drainage and public sanitary waste and civil in construction, specifically, the invention refers to a flush toilet installed in sanitary areas for drainage and domestic waste, in order to bring technical efficiency, economic efficiency, friendly and suitable for many different environments.
Technical Nature of the Invention
It is known that the current flush toilet on the Vietnam market are designed for the following purposes: drainage and sanitary waste, preventing odor from drain escape from the exhaust tube. To solve that problem, types of current flush toilets on the market has a similar shape, including an elliptical-shaped toilet bowl, an S-shaped exhaust tube and a rectangular water tank. The flush toilet with S-shaped exhaust tube is operated as following: water from the water tank comes down strongly with a large quantity of water creating pressure to push waste and sewage through S-shaped exhaust tube and down into steptic tank, after water and waste down into the steptic tank, the S-shaped exhaust tube leaves a sufficient amount of water to preventing odor from drain escape from the exhaust tube. However, the above flush toilets have the disadvantages following:
When operating, it is required to exhaust a large quantity of water creating pressure to push water, waste through S-shaped exhaust tube into the steptic tank, so the flush toilet must always have available water tanks with a minimum quantify of water from 3 to 6 liters of water, because the tap water usually is not strong enough to flush for toilet directly, from which the installation of a flush toilet must always together with a toilet tank that causes bulky for flush toilet, waste a lot of water and require standard installation techniques so that the
exhaust of water must create great pressure to push water and waste into the steptic tank.
The amount of water in the S-shaped exhaust tube is easily missed when the incorrect installation techniques or the toilet is mounted on moving vehicles such as ships, airplanes, cars,... because in the process of moving, the shaking phenomenona can shorten the amount of water in the exhaust tube, creating slits for odor escaping and polluting the surrounding environment.
The wastes easily back up the surface of the toilet causing bad smell and unhygienic if the drainage tube are clogged or in flooding prone areas, in the rainy season, the steptic tank will be flooded, the waste will back up because it have not a mechanism to prevent waste in the S-shaped exhaust tube.
Purpose of the Invention
Purpose of the invention prodives flush toilet solutions for types of public waste constructions or civil constructions to replace the solution of flushing toilets with S-shaped exhaust tube, limiting reimbursement the whole construction is difficult, bulky, easy to cause bad smell and prevent waste backed up causing unsanitary surrounding environment, water saving, environmentally friendly.
Technical Na ture of the Invention
In order to achieve the above purpose, the flush toilet following the invention consists of a porcelain toilet bowl with an elliptical shape, with large and small sizes, the toilet seat in below is also made of porcelain, inside of the toilet seat has a waste exhaust tube connected to the toilet bowl made from a soft rubber plastic tube, shaped like as chicken guts so it is also called a chicken guts exhaust tube, with an optima! length from 15cm to 20cm and a diameter from 6cm to 9cm, on top of the chicken guts exhaust tube are attached with the clamping mechanism always closed in above and the clamping mechanism is
always open in below, helping the waste deep down the steptic tank without wasting much water and being bad smell car backing wastes up the surface of the toilet bowl, causing unsanitary surrounding area, the trip lever mounted behind the toilet bowl, it may be made by plastic or porcelain depending on the type, the trip lever has a connection wire attached to the valve closing for water source and two opened and closed clamping mechanism on the chicken guts exhaust tube.
