Three-tank 13 is configured in the first water tank 11.The side 13B that this three-tank 13 has upper surface 13A and extends downwards from the outside genesis of upper surface 13A, and have near the bottom in the first water tank 11 lower ending opening 13C towards lower opening.In addition, be communicated with closet water channel 14 in the upper end of this three-tank 13.Be formed with inflow entrance 20A at the upstream extremity of closet water channel 14 and the upper end of three-tank 13.This inflow entrance 20A is configured in, with carry out toilet stool washing before holding state under the full-water level X1 of the first water tank 11 compare and lower position.
The downstream of closet water channel 14 is communicated with the rear portion of the urinal section 2 of toilet body 1.The flushing water that flows out from the downstream of closet water channel 14 is along the upper end side face of urinal section 2 and when a direction flows, flows on the surface of urinal section 2 and falls.So, the flushing water that flows out from the downstream of closet water channel 14 forms along the current of urinal section 2 rotations overlooking when observing, thereby so that dirt etc. concentrate on urinal section 2 central portion and with the plug-flows such as dirt to the toilet drainage passage 3 modes and flow.
The water level of the first open and close valve 31 in the second water tank 12 is reduced to the first designated water level Y1, Y2(with reference to Fig. 3) time seals flow export 12D.Although omitted the explanation of the detailed construction of this first open and close valve 31, its have with the lower water box that is applied in water-washing type toilet closet etc. in, can be to the draining valve that the small-large flow flushing is switched identical structure.That is to say, the first open and close valve 31 can be as follows and is driven, that is, set the first designated water levels (Y1, Y2) of two sealing flow export 12D, and select one among different two the first designated water level Y1, the Y2 in the second water tank 12 to seal flow export 12D.
In addition, the first open and close valve 31 has the operating portion 31A for open flows outlet 12D.This operating portion 31A is formed, can optionally carry out the flushing of high flux flushing and low discharge, wherein, described high flux flushing is, be supplied to the more flushing of the water yield of the flushing water of urinal section 2, described low discharge flushing is to compare the less flushing of the water yield of the flushing water that is supplied to urinal section 2 with high flux flushing.When in the mode of carrying out high flux flushing operating portion 31A being operated, the the first designated water level Y2 of the low side of water level in the second water tank 12 during the first open and close valve 31 sealing flow export 12D is selected, when in the mode of carrying out the low discharge flushing operating portion 31A being operated, the first designated water level Y1 of the water level higher side in the second water tank 12 during the first open and close valve 31 sealing flow export 12D is selected.Namely, when carrying out high flux flushing, when the water in the second water tank reaches the first designated water level Y2 of low side, the first open and close valve 31 sealing flow export 12D, when carrying out the low discharge flushing, when the water in the second water tank reaches the first designated water level Y1 of higher side, open and close valve 31 sealing flow export 12D.
The second open and close valve 32 is arranged on the first water channel 21.The second open and close valve 32 is, have with the second water tank 12 in the mode of variation interlock of water level and the ball float plug of the float 32A that moves up and down.This second open and close valve 32 is set to, and the water level in the second water tank 12 is to drive valve or close valve when being higher than the first designated water level Y1, Y2 and being higher than the water level of full-water level X1 of the first water tank 11.
The 3rd open and close valve 33 is arranged on the second water channel 22.The 3rd open and close valve 33 is, have with the first water tank 11 in the mode of variation interlock of water level and the ball float plug of the float 33A that moves up and down.The 3rd open and close valve 33 is set to, and drives valve or closes valve when the water level in the first water tank 11 is full-water level X1.
Next, the toilet stool washing action of water-washing type toilet closet with this structure described.
Shown in Fig. 2 A, in this water-washing type toilet closet, under the holding state before carrying out toilet stool washing, the first water tank 11 and the second water tank 12 have flushing water with the state of full-water level X1, X2.Under this state, shown in Fig. 2 B, the operating portion 31A of the first open and close valve 31 is operated, thus the flow export 12D of open the second water tank 12.Thus, this toilet bowl flush device 10 comes into effect toilet stool washing.When the flow export 12D of the second water tank 12 was open, the flushing water in the second water tank 12 flowed out in the first water tank 11 from flow export 12D, thereby the water level in the second water tank 12 will reduce.On the other hand, because flushing water flow in the first water tank 11 from the second water tank 12, therefore, at the initial stage of carrying out toilet stool washing, the water level in the first water tank 11 will rise slightly.
And when the water level in the second water tank 12 was reduced to the second designated water level Z, the second open and close valve 32 was driven valve, and the first water channel 21 is open.When the first water channel 21 is open, from injection nozzle 20B ejection flushing water, by this flow of water, thereby make three-tank 13(the first water tank 11) in flushing water be introduced in the inflow entrance 20A.Therefore, this toilet bowl flush device 10 can be supplied with to the urinal section 2 of toilet body 1 flushing water of large flow.And the water level in the first water tank 11 and the second water tank 12 will continue to reduce.
When the water level in the second water tank 12 is reduced to the first designated water level Y1, Y2, shown in Fig. 3 A, B, the first open and close valve 31 sealing flow export 12D.At this moment, at the 31A of manipulation operations section in the mode of carrying out the low discharge flushing in the operated situation, as shown in Figure 3A, be under the interior residual state (water level is the first designated water level Y1) that flushing water about half arranged of the second water tank 12 the first open and close valve 31 sealing flow export 12D.On the other hand, at operating portion 31A in the mode of carrying out high flux flushing in the operated situation, shown in Fig. 3 B, be in the second water tank 12 almost under the not residual state (water level is the first designated water level Y2) that flushing water arranged the first open and close valve 31 sealing flow export 12D.
During this period, when the water level in the first water tank 11 reduced from full-water level X1, the 3rd open and close valve 33 was driven valve.Thus, flushing water flow in the second water tank 12 from the second water channel 22.And after the first open and close valve 31 had sealed flow export 12D, the water level in the second water tank 12 rose.
And when the water level in the second water tank 12 rises to the second designated water level Z, as shown in Figure 4, the second open and close valve 32 will close valve, thereby make 21 sealings of the first water channel.Thus, stop from the ejection of the flushing water of injection nozzle 20B, thereby finish to the supply of the flushing water of urinal main body 1.At this moment, be not less than the mode of the lower ending opening of three-tank 13 with the water level in the first water tank 11, and set the second designated water level Z.Therefore, can in during injection nozzle 20B ejection flushing water, the state that flushing water is arranged that is full of will be maintained inevitably in the three-tank 13.Thus, can prevent from effectively from the flushing water of the injection nozzle 20B of jet pump device 20 ejection air being incorporated into situation in the inflow entrance 20A.Therefore, can prevent effectively that jet pump device 20 is introduced air and the sound that sends.
In situation about the operating portion 31A of the first open and close valve 31 being operated in the mode of carrying out the low discharge flushing, select the first designated water level Y1 of water level higher side and make the first open and close valve 31 sealing flow export 12D.Therefore, and in the mode of carrying out high flux flushing the situation that the operating portion 31A of the first open and close valve 31 operates is compared, can be shortened the time that water levels in the second water tank 12 rise to the second designated water level Z.That is, seal in advance the first water channel 21, thereby stop in advance the ejection from the flushing water of injection nozzle 20B.Therefore, when in the mode of carrying out the low discharge flushing operating portion 31A of the first open and close valve 31 being operated, can reduce the water yield of the flushing water of supplying with to toilet body 1.In this way, because this toilet bowl flush device 10 can be according to the behavior in service of water-washing type toilet closet, and the water yield of the flushing water that is supplied to urinal section 2 is changed, therefore can carry out well toilet stool washing.
In addition, this toilet bowl flush device 10 is according to the SEA LEVEL VARIATION in the second water tank 12, and the second open and close valve 32 is opened and closed.The flow that is supplied to the flushing water the second water tank 12 from the second water channel 22 changes according to pressure of supply water.That is, compare when low with pressure of supply water when pressure of supply water is higher, the flow that is supplied to the flushing water of the second water tank 12 will increase.Therefore, compare when low with pressure of supply water when pressure of supply water is higher, the water level in the second water tank 12 will rise to the second designated water level Z in advance.Therefore, compare when low with pressure of supply water when pressure of supply water is higher, the second open and close valve 32 will close valve in advance.That is, compare when low with pressure of supply water when pressure of supply water is higher, will stop in advance from the ejection of the flushing water of injection nozzle 20B, thereby finish in advance to the supply of the flushing water of toilet body 1.
In addition, about flowing through the first water channel 21 and from the flushing water of injection nozzle 20B ejection, the phase specific discharge will increase when also hanging down with pressure of supply water when higher for pressure of supply water.In addition, compare when weak (flow is less) with the flow of water when strong (flow is more) from the flow of water of the flushing water of injection nozzle 20B ejection, be introduced into three-tank 13(the first water tank 11 in the inflow entrance 20A) flow of interior flushing water will increase.Therefore, compare when low with pressure of supply water when pressure of supply water is higher, the flow that is supplied to the flushing water of toilet body 1 will increase, thereby will finish in advance to the supply of the flushing water of toilet body 1.In this way, even this toilet bowl flush device 10 in the situation of pressure of supply water change, also can reduce the error of the water yield of the flushing water of supplying with to toilet body 1.
Therefore, the toilet bowl flush device 10 of embodiment 1 can be supplied with the stable water yield to toilet body 1, thereby can carry out well toilet stool washing.
The water level of the second water tank 12 continues to rise by the flushing water that flows into from the second water channel 22.And as shown in Figure 4, the flushing water that overflows from the second water tank 12 will flow in the first water tank 11, thereby the water level in the first water tank 11 is risen.When the water level in the first water tank 11 rises to full-water level X1, the 3rd open and close valve 33 will close valve, thereby seal the second water channel 12.Thus, the first water tank and the second water tank have flushing water with the state of full-water level X1, X2, carry out toilet stool washing holding state before thereby return to.
As discussed above, the toilet bowl flush device 10 of the water-washing type toilet closet of embodiment 1 can be carried out toilet stool washing under power free condition.
＜embodiment 2 〉
As shown in Figure 5, the toilet bowl flush device 110 of the water-washing type toilet closet of embodiment 2 is different from embodiment 1 on following this point, and described point is only to have set the first designated water level of the first open and close valve 131 sealing flow export 12D.Other structure is identical with embodiment 1, the symbol identical to identical structure tag, and detailed.
The first open and close valve 131 is set to, thereby when operating portion 131A being operated open flows outlet 12D, almost not residual in the second water tank 12 have the state (water level is the first designated water level Y2) of flushing water to seal down flow export 12D.Therefore, this water-washing type toilet closet can when carrying out the flushing of closet, be supplied with the about equally flushing water of the water yield to urinal at every turn.
Therefore, the toilet bowl flush device 110 of embodiment 2 also can be supplied with the stable water yield to toilet body 1, and can carry out well toilet stool washing.
＜embodiment 3 〉
As shown in Figure 6, the toilet bowl flush device 210 of the water-washing type toilet closet of embodiment 3 is different from embodiment 2 on following this point, and described point is to have the 4th open and close valve 34 that is arranged on the first confession waste supply canal 21.Other structure is identical with embodiment 2, the symbol identical to identical structure tag, and detailed.
The 4th open and close valve 34 is, have with the first water tank 11 in the mode of change interlock of water level and the ball float plug of the float 34A that moves up and down.The 4th open and close valve 34 is set to, the water level in the first water tank 11 when being reduced to the water level W of lower ending opening of a little higher than three-tank 13, closes the water level in the first water tank 11 valve, so that can not be lower than the lower ending opening of three-tank 13 in the process of carrying out toilet stool washing.
That is, thus the water level of the 4th open and close valve 34 in the first water tank 11 be down to moment before the water level that air can flow into from the inflow entrance 20A of jet pump device 20 and close valve and seal the first water channel 21.Even supposing the flow that flow into the flushing water in the second water tank 12 reduces, the valve that closes of the second open and close valve 32 is postponed, also can be by the valve that closes of the 4th open and close valve 34, thus prevent from effectively from the flushing water of the injection nozzle 20B ejection of jet pump device 20 air being introduced into situation in the inflow entrance 20A.Therefore, can prevent effectively that jet pump device 20 is introduced air and the sound that sends.
