Description

[Detailed Description of the Invention] This invention provides a flushing tank that removes and flushes dirt in the toilet bowl using the minimum amount of flushing water necessary, and in particular, all inputs other than the supply water pressure and the repellent pressure of the printing plate. The present invention relates to the disclosure of a water-saving tank that can provide discharged water at a required pressure without intervening a mechanism even in a low tank system.

Therefore, in the conventional flushing mechanism of this type, tap water was filled into a metering tank, and the required amount of flushing water stored in this tank was supplied to the toilet bowl by opening and closing a valve as needed. It is. However, in such conventional methods, dirt is washed and removed by a flow velocity ratio corresponding to the head from the horizontal line position in the tank, so when the flow velocity pressure is low, it is necessary to increase the flow rate commensurate with this. This was requested. Therefore, in general water washing tanks,
This system flushes and removes filth by discharging and supplying 10,000 c.c. to 20,000 c.c. worth of washing water into the toilet bowl within as short a time as possible.

The requirement for a large amount of treated water in the conventional washing tank has become a particular problem with the recent shift from high tank systems to low tank systems.

The use of a large amount of treated water is not just a problem of depletion of water resources, but also a number of difficulties in the treatment of human waste. In other words, in general urine processing, the amount of human waste to be processed is particularly large, requiring larger equipment, and in the case of the pumping method, even more transport costs are required. It is what was done. In addition, in a waste treatment system having a treatment basin for simple water washing, it takes time to ferment and decompose the waste, which also requires a treatment basin with a large capacity compared to the raw amount of incoming waste.

The present invention has been devised especially in view of the disadvantages of the prior art, and by assembling a pressurized tank into the low-tank type water washing mechanism, the amount of washing water used is reduced as much as possible, thereby saving water and disposing of human waste. This is intended to simplify the process. Accordingly, in the present invention, in order to achieve the effects of these characteristics, the structure is modified to include an appropriate shielding plate that is slidably or swingably installed in a closed pressurized tank in an airtight manner. The supply pipe is divided into two parts, and one sealed chamber a is connected with a supply pipe in which an auxiliary check valve is installed between which is opened when the pressure is reduced, and a discharge pipe in which a manually operated valve is installed. In view of this, the following specific embodiments and considerable design changes accompanying these embodiments are planned.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. Reference numeral 1 is a pressurized tank having a certain capacity and airtightness without being restricted by material, shape, etc. It is prepared.

The inside of such an airtight pressurized tank 1 is partitioned watertightly with a shielding plate 2 fitted in a slidable manner, for example, by interposing a packing material 3, and the partition is divided using the plate 2. A spring 4 for applying back pressure to the plate 2 is loaded in one of the sealed chambers b.

In the embodiment shown in FIG. 2, the spring 4 in the previous embodiment is omitted, and the plate 2 itself is formed into a so-called diaphragm-like plate. A supply pipe 5 and a discharge pipe 6 are installed in the sealed chamber b of the pressurized tank 1 thus divided.
are respectively opened to form a series, and a manually operated valve 7 is connected to the discharge pipe 6, and check valves 8a and 8b are connected to the supply pipe 5 at predetermined intervals,
An auxiliary check valve 9 is provided between the valves 8a and 8b, which is opened when the gap pressure within the valve partition becomes a negative pressure of a certain value or more.

To explain the operation of the flushing tank with such a configuration, first, tap water is supplied through valve 8.
Compared to the atmospheric pressure of tank 1 at a and 8b, usually 2
By having a supply pressure of Kg/cm ³ to 7 Kg/cm ³ , the shield plate 2 is released and pushed against the spring 4 in the shield plate 2 or the elasticity of the material of the plate 2 in the direction of the closed chamber b, sliding or swinging. This was the influx. When this supply water flows in, the valve 7 is usually closed, and the inflow water moves the shielding plate 2 and compresses the sealed chamber b, causing the compressed air pressure in the sealed chamber and the plate 2 to move. At the point where the sum of the elastic forces is balanced with the inflow water pressure, the valves 8a and 8b are closed, and the preparation for discharging the treated water is completed.

In addition, in the case where the main purpose is to apply back pressure to the sealed room a using the air pressure in the sealed room b and the bombardment pressure in the plate 2, Added spring 4 or plate 2
By setting its own elastic force below the inflow tap water pressure, it is easier to calculate the amount of treated water to be filled into the sealed chamber a, and there is no concern that this will impair its operation or effectiveness. It is something that cannot be done.

When the valve 7 is opened for filling the treated water, the treated water in the sealed chamber a is supplied under pressure into the discharge pipe 6 under the back pressure in the plate 2, and is also pumped into the sealed chamber a. As the back pressure decreases, the remaining treated water is pumped and supplied by the elastic force of the plate 2 itself.

With the dissipation of the treated water in the sealed chamber a, the valve 7 is closed again, and the airtight condition in the sealed chamber a is reproduced. A valve 8 is placed in a pressurized sealed chamber a.
The treated water is injected again through ports a and 8b.

In addition, due to damage to water pipes, valves 8a and 8b
Even when negative pressure is generated in the direction of the main supply pipe, the valves 8a and 8b operate in duplicate to prevent the backflow of accumulated treated water in the tank 1. Valve 8a when the negative pressure generated in the supply pipe 5 is large due to
An auxiliary valve 9 is also provided to prevent damage to 8b or leakage of accumulated treated water from this part.

The present invention has been able to eliminate the inconveniences of the above-mentioned prior art due to the characteristic structure and operation described above, and is capable of cleaning waste containing solid matter using an extremely small amount of treated water. This made it possible.

In particular, the present invention utilizes tap water pressure as it is, simplifies the operation section by eliminating the need for other pressurization inputs, and also quantifies the tap water and converts the treated water into quantitative categories. It has a discharge pressure applying structure that spans stages to quickly force-feed a certain volume of treated water into the toilet bowl, ensuring that filth can be washed with a small volume of treated water.

The unique feature of the structure of the present invention is that the use of a flush valve is avoided because the normal tap water supply pressure varies between 2Kg/cm ³ and 7Kg/cm ³ . This system was designed to quantify the discharge amount of treated water and to prevent flushing water from overflowing into the toilet bowl.

Therefore, in the washing tank according to the present invention, the processing pressure of washing water accompanying the use of a normal low tank is 0.45.
Kg/ ^cm3 , the treatment pressure is approximately 17.5Kg/ ^cm3 , and the amount of treated water used is around 200c.c., in order to save water resources and reduce the amount of treated human waste. It is.
