Description

Toilet bowl < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a toilet seat, and more particularly, to a water saving toilet seat capable of discharging dirt using a small amount of water.

Generally, the toilet water stores a certain amount of water, discharges the wash water stored in the water storage tank into the toilet, and discharges the dirt in the toilet to the sewer pipe by the generated pressure. Such a toilet seat discharges dirt out of the toilet by a so-called siphon action generated by the pressure of the washing water discharged from the water storage tank, and typically uses 10 liters or more of water to discharge the dirt.

1 is a cross-sectional view of a general toilet.

1, the conventional toilet bowl includes a toilet body 10 and a water storage tank 20 provided at a rear upper end of the toilet body 10, and the water storage tank 20 has an outlet 20a formed at a lower portion thereof And the outlet 20a communicates with the inlet 10a of the toilet body 10. [

The toilet bowl body 10 is provided with a bowl portion 11 in which water is stored so that dirt is introduced and a drain hole 11a in which water stored in the bowl portion 11 is drained. The drain hole 11a is connected to a drain trap 12) to the sewer pipe.

The water storage tank 20 includes a water supply packing 21 that opens and closes the outlet 20a and an operation lever 22 that is provided outside the water storage tank 20 to open and close the water supply packing 21, The lifting and lowering operating portion 23 is connected to the water supply packing 21 by the chain 24 so that the operation of the lifting and lowering operating portion 23 can be controlled by the turning operation of the lever 22, And the water supply packing 21 is moved upward and downward through the chain 24 to open and close the outlet 20a so that water stored in the water storage tank 20 flows through the outlet 20a and the inlet 10a The supply to the bowl portion 11 is performed.

A water supply unit 25 is provided in the water storage tank 20 and the water supply unit 25 is connected to a water pipe via a valve to open and close the valve according to the water level in the water storage tank 20, ) Always stores a certain level of water.

When the user operates the operation lever 22 after using the toilet, the water supply packing 21 moves upward and the outlet 20a is opened so that the water stored in the water storage tank 20 rapidly flows into the bowl 11 The water in the bowl portion 11 is discharged to the sewer along the drain hole 11a and the drain trap 12 due to the siphon action as the water level in the bowl portion 11 increases.

However, in such a conventional toilet bowl, water is discharged together with the dirt along the drain trap by the water pressure rapidly supplied from the water storage tank 20, so that a large amount of water of about 7 to 13 liters is consumed to discharge the dirt, There is a disadvantage that large noise is generated in the process of discharging dirt. Meanwhile, in order to save the amount of washing water required for washing the soil, the water level of the water tank may be adjusted to a low level. However, There is a problem that cleaning of the dirt of the toilet can not be performed cleanly.

On the other hand, the supply of washing water to be used in the toilet is made through a water pipe. In the situation where it is difficult to steadily supply domestic water due to urbanization and environmental pollution, the use of excessive washing water used for the toilet water, It can be said that it is against the atmosphere for.

In this respect, there are various proposals for saving the washing water used in the toilet.

For example, in Japanese Patent Application Laid-Open No. 10-2011-0137526 (Published on Dec. 23, 2011), compressed air is jetted to a flow of water discharged through a discharge port of a toilet to rapidly discharge sewage in a discharge pipe, However, since a compressor for generating compressed air and a control unit for controlling the driving of the compressor are essential components, it is necessary to supply power to the toilet in addition to a separate facility, thereby incurring additional costs for the water saving of the toilet And maintenance and management of electric parts are required.

As another example, the registered patent No. 10-1074659 (registered on Dec. 12, 2011) is a toilet which is used for toilet and recycles wastewater discharged for recycling for toilet water to save raw water (water supply) The present invention proposes a water saving device, but it is an essential constitution of a piping system including a wastewater tank for recovering wastewater discharged from a washstand, a pumping means for supplying wastewater between the water tank of the toilet and a plurality of valves and cylinders, It is necessary to secure a facility space, and a power supply facility for operating the pumping means is required, so that it is difficult to apply the present invention to a conventional toilet.

As described above, the conventional toilet bowl having a water saving function requires a separate additional facility outside the toilet for the water saving function, which may cause a restriction on the installation space, requires an electric driving unit, There is a problem that inconvenience occurs.
