Abstract
To make it possible to efficiently generate a siphoning action with a small quantity of water by providing a water spraying section for supplying cleaning water from upper section of a water discharge passage to the inner wall of a downstream side water discharge passage, in a trap water discharge passage. A control device 15 opens a rim valve in an automatic two-way selector valve 14 in accordance with a signal from a manipulating section 16 so as to feed cleaning water into a bowl section 3 of a closet 1 which is therefore subjected to precleaning. When a detection value by flowmeter 19 coincides with a set value of precleaning water quantity, the control device 15 closes the rim valve. Then the control device 15 opens a shower valve in the selector valve 14 so as to jet water from a shower unit 7 into a flow-out unit 4c in a trap draining passage 4. Accordingly, the cleaning water discharges air into a water discharge pipe from a flow-out port 6 while it swallows up air in an flow-out passage 4c so as to generate a negative pressure. Further, turbid water 23 in the bowl section 3 overflows a weir 4b in the water discharge passage 4 and is led into a flow-out passage 4c so that the negative pressure is increased, thereby a siphoning action generates.

Following with reference to the description of drawings embodiments of the invention.
Fig. 1 and Fig. 2 illustrate the 1st embodiment according to rinse water supply device of the present invention.The big chamber pot 10 of rinsing type has the spherical portion 11 of accepting to retain dirt sewage; Separate with next door 11a and spherical portion 11, communicate, be roughly the curved drain 12 of reverse U shape with the bottom of spherical portion 11; Be the flange part 13 that surrounds the top edge of spherical portion 11 like cylindric seemingly.The flange part 13 inner cavities that form, the circulation passage 13a of formation rinse water.The part of circulation passage 13a is enlarged, form and give hydroecium 13d, give on the hydroecium 13d, offer the admission port 13b of rinse water at this.On the circumference of flange part 13, wear a plurality of rinse water supply hole 13c, and be connected with circulation passage 13a.The internal face that this rinse water supply hole 13c is worn into relative spherical portion 11 tilts.For example, by the rinse water supply hole 13c that inclination is offered, the emission direction that makes rinse water is than about 45 ° of horizontal direction deflection below.Like this, the rinse water of ejection produces spiral helicine current in spherical portion 11.
Curved drain 12 has the inflow entrance 12a that forms between the bottom of the leading section 11b of next door 11a and spherical portion 11.Bending part in the curved drain 12 that is roughly the U font is provided with the 12b of dykes and dams portion, promptly is discharged from when rinse water W surpasses the 12b of this dykes and dams portion.Make the flow pass 12c in the downstream of curved drain 12 become the straight tube shape of approximate vertical configuration, its bottom is provided with flow export 12d.
The part of the top 12e of curved drain 12 is made flat condition, be positioned at flow pass 12c directly on the top 12e of position, be equipped with a plurality of rinse water squit holes 14.This rinse water squit hole 14 is arranged to tilt slightly, in order to make the inwall ejection of rinse water towards the flow pass 12c of curved drain 12.Squit hole 14 is arranged to show greatly equally spaced radial so that rinse water can disperse the ejection.On the top of rinse water squit hole 14, the case 15 that can cover all these squit holes 14 is installed.
Be provided with the cover 17 of constitution equipment reception room 16 at the upper side of giving hydroecium 13d of big chamber pot 10, in reception room 16, accommodating the control appliance of supplying with rinse water.The rinse water supply pipe 19 that is connected with rinse water supply source 18 passes cover 17 and is inserted in the equipment holding chamber 16.This rinse water supply pipe 19 is divided into two halfway, is connected with spherical portion feed pipe 22 and curved drain feed pipe 23 respectively.Spherical portion feed pipe 22 is connected with the admission port 13b that faces toward to hydroecium 13d opening, disposes spherical portion electromagnetic switch valve (spherical portion valve) 20, atmospheric open valve 24 and flow transmitter 25 midway successively.Again, curved drain feed pipe 23 is connected through the space in the case 15 of rubber tubes 26 and rinse water squit hole 14, disposes curved drain midway successively with electromagnetic switch valve (aqueous dispersion ejection valve) 21, atmospheric open valve 27, flow transmitter 28.Rubber tube 26 is configured to roughly U font, and its bending part 26a is positioned at the dykes and dams portion low position of 12b than curved drain 12.
On the input interface circuit 33 of control device 30, connecting respectively from the flow transmitter 25 of being located at spherical portion feed pipe 22 with from holding wire 25a, the 28a of the flow transmitter 28 of being located at curved drain feed pipe 23.On the input interface circuit 33, also connecting starting input part 29 with firing switch 29b by holding wire 29a.Again, on the output interface circuit 34 of control device 30, connecting and linking spherical portion respectively, can spray with valve 21 transmit button action command signals with valve 20 and aqueous dispersion to spherical portion with valve 20 and the holding wire 20a, the 21a that disperse to spray with on the valve 21.
Then, the sequence of movement according to the rinse water supply device of present embodiment is described with reference to Fig. 3 and Fig. 4.
Utilize hand switch, seat switch or optical sensor etc., make firing switch 29b auto-closing, rinse water supply device just begins action.Come the initiating signal of self-starting input part 29 to be sent to control device 30, then, open spherical portion and be sent to spherical portion usefulness valve 20 from microprocessor 31 with the command signal of valve 20.Because spherical portion opens with valve 20, be supplied to admission port 13b by spherical portion feed pipe 22 from the rinse water of rinse water supply source 18.Rinse water in the circulation passage 13a of admission port 13b inflow flange part 13 sprays from rinse water supply hole 13c, in spherical portion 11, while form spiral helicine current to dirty.Therefore, be carried out cleaning (step S1) in the spherical portion 11.
The flow of supplying with the rinse water of spherical portion 11 detects by flow transmitter 25, and this flow signal is sent to the cleaning water yield integrating device 31a of control device 30, carries out the accumulative total (step S2) of confluent.The confluent that accumulative total goes out in comparison means 31b, make comparisons (step S3) with setting value.Reach setting in case supply with the water yield of spherical portion 11, the closing motion command signal just is sent to spherical portion valve 20, and spherical portion is closed (step S4) with valve 20.Like this, the main cleaning action in the spherical portion 11 finishes.
Come the initiating signal of self-starting input part 29 also to be sent to the timer 31c of control device 30, begin to carry out time counting (step S5) by timer 31c.In case gate time surpasses setting, promptly send out the command signal (step S6) of opening valve to the aqueous dispersion ejection of being located on the curved drain feed pipe 23 with valve 21 from control device 30.Because aqueous dispersion ejection is opened with valve 21, be supplied to rubber tube 26 from the rinse water of rinse water supply source 18 by curved drain feed pipe 23, flow into again in the case 15.The rinse water that flow in the case 15 are disperseed for 14 one-tenths radially by the rinse water squit hole, and spray towards the inwall of the flow pass 12c of curved drain 12, are supplied to the flow pass 12c of curved drain 12.Like this, the bubble that has been full of rinse water in the flow pass 12c of curved drain 12 and has generated thus flows out from flow export 12d.Because the mobilization of this air water fluid-mixing, produce negative pressure in the flow pass 12c, produce siphonage in the curved drain 12, the water and the discarded object that accumulate in the spherical portion 11 are just crossed the 12b of dykes and dams portion, and the flow pass 12c by curved drain 12 is discharged from again.Make to the spray volume that produces the necessary rinse water of siphonage has optimum value according to the regulations such as shape of curved drain 12, the control of the spray volume of this rinse water is carried out with flow transmitter 28.That is, control in the same manner with the confluent of supplying with spherical portion 11, detect flows by flow transmitter 28,31a adds up with integrating device, compares at comparison means 31b and setting value (step S7, S8).In case sprayed the rinse water that reaches ormal weight from rinse water squit hole 14, aqueous dispersion is sprayed and is just closed (step S9) with valve 21.
The time set that aqueous dispersion ejection is opened with valve 21 can be as shown in Figure 4, is set in the time that spherical portion just opening with valve 20.In this case, as shown in Figure 4, in time T 1, spherical portion 11 and rubber tube 26 both sides have the rinse water supply.By doing like this, can discharge the air in the rubber tube 26 by rinse water squit hole 14 in advance, just can efficiently bring into play to producing the rinse water ejection effect of siphonage.
In case the rinse water ejection that produces siphonage institute necessary amounts is finished, and the aqueous dispersion ejection is just closed with valve 21, because siphonage, the sewage in the spherical portion 11, dirt etc. are discharged from.But duration that should the discharge effect is controlled by timer 31c.That is, in case spherical portion is closed timer 31c just pick up counting (step S10) with valve 20.Through (with reference to Fig. 4) behind the stipulated time T2, the OPEN signal is sent to spherical portion valve 20, and spherical portion is opened once more with valve 20.Like this, rinse water is supplied in the spherical portion 11, its quantity delivered is same as described above, utilizes flow transmitter 25 to detect, and adds up (step S12) with integrating device 31a.More whether reached the confluent of stipulating (step S13) with comparison means 31b, when reaching the confluent of regulation, made spherical portion close (step S14) with valve 20.So just, can in spherical portion 11, reach the water shutoff (water level rising) of predetermined water level.And by closing spherical portion valve 20, a series of actions process of rinse water supply device also comes to an end.
Like this, because the rinse water squit hole 14 at the top by being located at curved drain 12 disperses ejection to rinse water in the flow pass 12c of curved drain 12, so, can make easily in the flow pass 12c to be full of rinse water, can use a spot of water, produce siphonage efficiently.In addition, the rinse water spray volume of supplying with curved drain 12 detects, carries out flow-control with flow transmitter 28, so can be being controlled to be the best for producing the necessary confluent of siphonage.Also have, because spherical portion is to control according to the confluent accumulated result of use traffic sensor 25,28 with the cut-off command that valve 20 and aqueous dispersion spray with valve 21, so, even produce pressure oscillation in rinse water supply source 18 or the rinse water supply pipe 19, also can supply with the rinse water of ormal weight all the time, can not produce the problem of confluent deficiency.Have again, owing to adopted after the cleaning action of spherical portion 11 finishes again the cleaning sequence that sewage etc. is discharged from curved drain 12, so even in spherical portion 11, under the very dirty situation, also can receive excellent cleaning effect.
Again, owing to be supplied to rinse water the rubber tube 26 of rinse water squit hole 14 to be provided with kink 26a, so be in the state that retains rinse water in the rubber tube 26 all the time.Therefore, can prevent that the stench in the curved drain 12 from leaking into the outside by rubber tube 26 and curved drain feed pipe 23.
In the above-described embodiments, the example that adopts following program is illustrated, promptly as shown in Figure 4, in the time that spherical portion is being opened with valve 20, then fetch boiling water and disperse ejection with valve 21, make the spherical portion cleaning action and produce simultaneously to the rinse water ejection effect of curved drain 12.
But this aqueous dispersion ejection also can be carried out after spherical portion is closed with valve 20 as shown in Figure 5 with the opening action of valve 21.In this occasion, aqueous dispersion ejection also can be without the timer 31c of control device 30 with the opening action command signal of valve 21, and with the shutdown signal of spherical portion with valve 20.Such feedwater action also can be used spherical portion is formed one two-way automatic transfer valve with valve 20 and aqueous dispersion ejection with valve 21.
Time diagram and for example shown in Figure 6 is such, also can open spherical portion with valve 20 in the time that the aqueous dispersion ejection is being opened with valve 21, begins to carry out water shutoff.Do like this,, during the water in the spherical portion 11 is being discharged from, then supply water to spherical portion 11 owing to producing siphonage from rinse water squit hole 14 ejection rinse water.Therefore, can prevent because of siphonage spherical portion 11 becomes empty the situation that curved drain 12 and spherical portion 11 are connected with anhydrous state.Therefore, can prevent to invade spherical portion 11, and can prevent the noise that the ejection because of rinse water at rinse water squit hole 14 places causes from the stench of curved drain 12.
Time diagram that also can be as shown in Figure 7 is such in addition, makes towards the dispersion ejection of the rinse water of curved drain 12, and intermittently carry out at the interval that separates regulation.Just,, carry out timing,, fetch boiling water and disperse ejection with valve 21 through behind the stipulated time T3 with timer 31c at first after curved drain 12 is supplied with rinse water and finished, once more by rinse water squit hole 14 to curved drain supply rinse water.Like this, the siphonage in curved drain 21 is proceeded for a long time, the ability of the dirt that swims in the drain ball shape portion 11 is improved.
Again,, for example can adopt to have the impeller that rotates with flow, and a signal of telecommunication corresponding with this rotation is as the device of output as flow transmitter 25,28 with being directly proportional.As other flow-control means, also can be by pressure gauge be set in feed pipe, and according to carrying out the actuation time of detected pressure value control timer and the opening action time of control electromagnetic switch valve.
Fig. 8 is with Fig. 1 suitable figure of diagram according to rinse water supply device the 2nd embodiment of the present invention.
The characteristics of present embodiment are that the downstream of curved drain 12 is connecting the water-stop generating mechanism, simultaneously, makes the supply source of the rinse water that sprays to curved drain 12 dispersions inequality with the supply source of the rinse water of supplying with spherical portion 11.It is identical that other formation and embodiment shown in Figure 1 come down to, so identical formation has been put on identical symbol and omitted explanation.
