In recent years, various types of forced drainage type toilet bowl have been developed and are being practiced in the art to satisfy drainage performance and sensibility quality better than natural drainage type toilet with a small amount of washing water.

FLUSH VALVE TYPE toilet flush valve, which is a typical forced drainage type toilet, uses a diaphragm type large flush valve directly connected to piping in the building, and high pressure washing water is pushed into the inside of the toilet to push out the dirt. However, since the water (washing water) is used in a similar manner, the water pipe must also be provided with a separate large-diameter pipe, which is disadvantageous in that the quality of the sensibility is remarkably deteriorated due to the noise.

On the other hand, a washing water valve technology capable of controlling a high water pressure washing water by combining a fill valve using a diaphragm opening / closing action and a valve automatic controller using an electric driving mechanism such as a solenoid valve is currently a representative electronic It is widely used as a drainage control device.

A conventional water dispenser of a bidet type sanitary ware is disclosed in Korean Patent No. 10-1038063 as a prior art of an electronic drainage control device of a forced drainage toilet. And a support member which is seated on the first and second pipes of the water supply unit and protrudes from the coupling rod through which the interior of the water supply unit is protruded, A supply control unit provided with a fill valve for opening and closing each of the two pipes, and a supply adjusting pin mounted on a coupling rod of the support member to adjust supply of wash water; An operation part for opening the drain hole of the water supply part and supplying the washing water to the rim side of the bowl part and the jet water channel so that the fill valve of the supply control part operates; And an air inflow part for introducing outside air while descending at a back pressure and self weight when the washing water supplied to the water supply part is backward flowed.

However, since the conventional art does not operate as a completely closed type piston like a cylinder inside the cylinder, it can not be used at low pressure, and the flow rate cross-sectional area of the pressure water replenishment pipe is basically small, .

At this time, the upper portion of the pressure chambers 230 and 330 is closed by the plunger members 412 and 512 of the solenoid valves 410 and 510, and the lower portion is closed by the opening and closing members 420 and 520.

In addition, as will be described later, the pressure water serves to limit the upward movement of the opening and closing members 420 and 520 elastically supported by the first springs 426 and 526.

When the plunger members 412 and 512 are in the lowered state, the orifices 422 and 522 of the open / close members 420 and 520 together with the plunger members 412 and 512 are provided with the second packings 416 and 516 at the lower ends of the plunger members 412 and 512, As shown in Fig.

The second springs 418 and 518 are provided on the outer sides of the second packings 416 and 516. The second springs 418 and 518 are inserted into the space portions 232 and 333 formed inside the pressure chambers 230 and 330 by the plunger members 412 and 512, The plunger members 412 and 512 and the second packings 416 and 516 press the opening and closing members 420 and 520 so as to improve the sealing force of the orifices 422 and 522 formed at the upper ends of the opening and closing members 420 and 520 And at the same time, enhances the sealing force of the flow paths 220 and 320 by the opening and closing members 420 and 520.

When the electric signal is transmitted from the control unit 430 to the solenoid valves 410 and 510, the plunger members 412 and 512 are driven to be driven upward to open the orifices 422 and 522 and are accommodated inside the space portions 232 and 332 of the pressure chambers 230 and 330 The pressure water is discharged to the drainage paths 210 and 310 through the orifices 422 and 522 and the opening and closing members 420 and 520 formed upward and downward so that the opening and closing members 420 and 520 elastically supported by the first springs 426 and 526 move upward The flow channels 220 and 320 are formed between the body 100 and the drain lines 210 and 310 of the first and second drain lines 200 and 300 so that the wash water supplied from the water line 110 flows through the flow channels 220 and 320, 2 to the drainage passages 210 and 310 of the water pipes 200 and 300.

At this time, the control unit 430 controls the control units 400 and 500 of the first and second water pipes 200 and 300 to be selectively operated so that the wash water can be efficiently supplied to the bowl side and the jet unit side of the toilet bowl .

3 (a) to 3 (e), the operation of the electronically controlled toilet bowl and the drainage valve device 50 for a bidet unit type toilet bowl will be described.

First, as shown in FIG. 3 (a), washing water is supplied to the body 100 side through the water supply pipe 110.

3 (b), when an electric signal is transmitted from the controller 430 to the solenoid valve 410 of the first water pipe 200, power is applied to the core 414 and the plunger member 412 The opening of the orifice 422 of the opening and closing member 420 causes the pressure stored in the space 232 to be discharged through the orifice 422 toward the drainage path 210 of the first drain pipe 200 The pressure of the space portion 232 is lowered.

3 (c), when the pressure of the space portion 232 is lowered, the opening and closing member 420 is raised by the elasticity of the first spring 426, The flow channel 220 is formed between the body 100 and the first drain pipe 200 by the upward movement so that the wash water is supplied from the body 100 to the drainage channel 210 and thus the wash water can be supplied to the bowl side of the toilet. .

3 (d), when power is applied to the core 514 to cause the plunger member 510 to move to the solenoid valve 510 of the second water pipe 300 by the control unit 430, The orifice 522 of the opening and closing member 520 is opened so that the pressure of the water stored in the space portion 332 flows through the orifice 522 to the drain line 310 of the second drain pipe 300 The pressure of the space portion 332 is lowered.

3 (e), the opening / closing member 520 is raised by the elasticity of the first spring 526 as the pressure of the space portion 332 is lowered, The washing water is supplied from the body 100 to the drainage path 310 and the washing water supplied to the drainage path 310 is discharged to the outside of the body of the toilet 100. [ So that the cleaning of the toilet can be performed.

The control unit 430 transmits an electric signal to the solenoid valve 410 of the first water pipe 200 to lower the plunger member 412. The lower end of the plunger member 412 moves the plunger member 412 downward, The orifice 422 is closed and the opening and closing member 420 is also lowered so that the flow path 220 formed between the body 100 and the first drain pipe 200 is closed.

After the above-described process, when the flow path 320 formed in the second drain pipe 300 is closed by the signal of the controller 430 and the flow path 220 of the first drain pipe 200 is further opened The cleaning of the toilet bowl using the drain valve device 50 according to the present invention is completed.

The upward and downward stroke distances of the opening and closing members 420 and 520 are shorter than the ascending and descending stroke distances of the plunger members 412 and 512 because the washing water flowing through the flow paths 220 and 320 is lifted So that it can be utilized as the pressure water used for driving.

That is, even when the plunger members 412 and 512 and the opening and closing members 420 and 520 are both raised due to the difference in the stroke distance as described above, the orifices 422 and 522 of the opening and closing members 420 and 520 are kept open, A part of the washing water flowing from the body 100 through the flow paths 220 and 320 formed by the rising of the members 420 and 520 is supplied to the inside of the space parts 232 and 332 through the orifices 422 and 522 of the opening and closing members 420 and 520.

When the plunger members 412 and 512 and the opening and closing members 420 and 520 are lowered, the orifices 422 and 522 are first closed by the lowering of the plunger members 412 and 512 as described above, The washing water supplied to the inside of the space portions 232 and 332 with the flow paths 220 and 320 opened is stored in the space portions 232 and 332 even when the flow paths 220 and 320 are closed, And is used as the pressure water at the time of the next open / close member 420.520 rising.

The backflow prevention part 600 is provided on the upper part of the body 100. When the washing water is not supplied through the water supply pipe 110, the backflow prevention part 600 discharges water from the bowl side of the toilet, And serves to prevent reverse flow of washing water or contaminated water to the valve device 50 side.

More specifically, if washing water is not supplied through the water supply pipe 110 of the body 100 due to a single or the like, the inside of the body 100 is evacuated and the body 100 and the first and second water pipes The washing water or the contaminated water may be backflowed from the bowl side of the toilet bowl to the drainage pipes 210 and 310 of the first and second drain pipes 200 and 300 due to a pressure difference generated between the backflow prevention part 600 and the backflow prevention part 600, Thereby preventing backflow of wash water or contaminated water.

The backflow prevention part 600 includes a backflow prevention member 610 coupled to the air inlet pipe 120 formed on the upper part of the body 100. The backflow prevention part 600 has an upper end A flange 612 is formed, and a third packing 616 is coupled to the lower end.

The third packing 616 is closely attached to the partition wall 122 formed on the body 100 by the elasticity of the third spring 614 to be described later so that the air inflow pipe 120 and the air inflow path 124 To prevent the inflow of air into the inside of the body 100 through the openings.
