Summary of the invention
Invent problem to be solved
But although in the portable toilet that possesses the warm water washing function, the excremental outbalance of taking in also is important problem as the improvement of the water tank of the supply source of warm water.Namely, in general family etc., owing to the warm water toilet flusher that arranges in the mode on the flange of the closet that is configured in rinsing type is set to, the aqueduct that Chang Shicong is connected to running water tube is supplied with running water, does not therefore need to consider supply of groundwater.In addition, because warm water has utilized the hydraulic pressure of running water from the injection of flooding nozzle, therefore do not need for the special motor and the pump that spray warm water.
But, because in not being connected to the general portable toilet of running water tube, the supply of water is mainly implemented by water tank, therefore defines the upper limit of utilizing number of times according to the pondage of water tank, thereby replenishes before need to the make-up water in water tank exhausting.But, grasp the surplus of the make-up water in the water tank when normal and note the opportunity of replenishing, be very loaded down with trivial details for hindering patient and nursing staff.Especially expect that the management that heavy patient, heavy the wounded implement portable toilet is very difficult, in this case, owing to sloppy management, when forgeing the make-up water that causes in the water tank and exhausting, warm water in the warm water water tank also will reduce, thus, generation causes the danger of scalding because of hot water thereby the temperature of warm water in the warm water water tank will rise.
And, in the existing portable toilet of the hydraulic pressure that can't utilize running water, as shown in figure 22, because water tank T1 and warm water water tank T2 become fully independently individual, therefore supply-water pump P is set, and the ejection side of this supply-water pump is connected with warm water water tank T2, and on the other hand, the suction side that makes like that as shown in the drawing enters in the water tank T1.
In the existing portable toilet that consists of in the above-described manner, when the beginning of indication flushing, thereby the make-up water that supply-water pump P will work to water tank T1 aspirates, and this make-up water that aspirates is supplied among the warm water water tank T2.Thus, the hydraulic pressure in the warm water water tank will rise, and warm water is supplied to buttocks flooding nozzle A or private parts flooding nozzle B via flushing water switch unit E, and warm water ejects from the top of buttocks flooding nozzle A or private parts flooding nozzle B.
By consisting of by this way, because supply-water pump P needs following ability, namely, thereby can implement warm water from the ability of the injection of each nozzle A, B from the ability of water tank T1 suction make-up water and the pressure that is used for improving in the warm water water tank T2, thereby therefore exist the pump unit maximization space efficiency that comprises motor to reduce, and the problem of power consumption increase.In addition, be connected state on the water tank T1 owing to being in water supply hose H, therefore need numerous and diverse labour and time, namely, when taking off water tank T1 in order to replenish make-up water from main body, must pull up water supply hose H from water tank T1, and after having replenished make-up water, to water tank T1 water supply hose H is installed.
But in the situation of the said structure that has adopted water tank, the action of hydrostatic pressure of the make-up water of water tank is in the warm water of warm water water tank, and this hydrostatic pressure performance is to the effect of warm water from the injection application of force of nozzle.Thus, owing to can adopt the less pump unit of driving force, therefore can realize miniaturization, province's electrification of pump unit.Therefore, the driving force of pump unit be the maximum that obtained when in water tank, having been replenished to greatest extent make-up water hydrostatic pressure as benchmark definite.
So, in the driving force that makes the pump unit corresponding to the state that farthest obtains hydrostatic pressure, thereby implement ideally warm water in the situation of the injection of nozzle, along with the flushing repeatedly implemented, hydrostatic pressure also will reduce gradually.That is, because when the water level of the make-up water of water tank reduces, warm water also will reduce from the jet power of nozzle, thereby can't implement sufficient flushing, so before the make-up water of water tank exhausts, must make warm water become fixing from the spray regime of nozzle.
Be used for solving the method for problem
Relate to a kind of portable toilet among the present invention, it arranges Warm water flushing toilet seat in the section of taking one's seat, and the excrement-collecting pallet is set below this Warm water flushing toilet seat, and rear side configuration water tank and warm water water tank at backrest, described portable toilet is characterised in that, when water tank had been configured to the top of described warm water water tank, the feed water inlet of this water tank was connected with the water inlet of warm water water tank, thereby the action of hydrostatic pressure of the make-up water of water tank is in the warm water of warm water water tank.
In addition, described portable toilet is characterised in that, adopts the mode that the negative pressure relief valve is set at described water tank, and arranges and can when making described water tank from the disengaging of warm water water tank and upset, stop the negative pressure relief valve of the leakage of make-up water.
The invention effect
According to the present invention, because when water tank being configured to the top of warm water water tank, the make-up water of water tank flow into the inside of warm water water tank, so the action of hydrostatic pressure of the make-up water of water tank is in the warm water of warm water water tank.Namely, because the warm water Chang Shixiang emission direction of warm water water tank is biased, therefore can reduce from buttocks flooding nozzle or private parts flooding nozzle and spray the needed power of warm water and energy, thereby can realize the miniaturization of the responsible pump unit that sprays, can realize cost thus.Meanwhile, can reduce the power consumption of pump unit, and improve space efficiency.In addition, owing to not needing for the water supply hose from water tank suction make-up water, easily mobility is comparatively excellent thereby the dismounting of water tank is become, thereby becomes simple to the adjunctive program that water tank replenishes make-up water.
In addition, thereby by negative pressure that the negative pressure relief valve can solve water tank inside being set along with the supply supply of groundwater increases, thereby the problem that the hydrostatic pressure that warm water bears reduces gradually.And, since consist of the negative pressure relief valve as follows, that is, when enforcement replenishes the adjunctive program of make-up water to water tank, in the situation that make water tank spin upside down the mode that make-up water can not leak, therefore can avoid make-up water from the situation of this negative pressure relief valve drippage.

Below with reference to the accompanying drawings embodiments of the present invention are described.Portable toilet of the present invention 1 is similarly the mode of coming the chair shape of supporting base section by four legs with known portable toilet, illustrates main parallax stereogram in Fig. 1, illustrates rear perspective view in Fig. 2.Shown in this each figure, thereby the central portion opening has and is provided with leg 3 on four angles of pedestal 2 of opening 2a and can stands.
On the bottom surface of described pedestal 2, with the state of the whole opening 2a that covers this pedestal 2, and can the mode that collected defecation is processed be disposed removable excrement-collecting pallet 4.The upright handrail tube 5 that arranges on the top of the leg 3 at place, the both sides of the front end that is arranged at described pedestal 2 is bent as shown in Figure 1 and Figure 2 like that towards the rear of pedestal 2, and disposes backrest 6 at the position of the back of the human body that is equivalent to take one's seat.On the other hand, on the top of the leg 3 at place, the both sides of the rear end that is arranged at pedestal 2, uprightly be provided with and be bent to the roughly stationary pipes 8 of コ word shape.In addition, the upper surface at pedestal 2 disposes the toilet seat 7 that opens and closes at above-below direction in electronic mode.
The main part of portable toilet 1 of the present invention consists of in the above-described manner, implements the needed functional imperative such as flushing processing, and centralized configuration is in the position at the back side of the back of the human body that is equivalent to take one's seat and buttocks.Fig. 3 to Figure 11 is the figure of the configuration status of presentation function key element, and as shown in Figure 3, warm water water tank 9 is configured and is fixed in left comer section place on the pedestal 2.
Shown in the cutaway view of Fig. 4, though described warm water water tank 9 is built-in with the airtight ducted body of electric heater 10, float switch 11 and thermistor 12 for section within it, but possesses at an upper portion thereof water inlet 9A, wherein, described electric heater 10 is used for generating warm water, the signal of telecommunication that described float switch 11 acquisitions detect for the deficiency to warm water, described thermistor 12 obtains to be used for making warm water maintain the signal of telecommunication of preference temperature.As shown in figure 10, thereby this water inlet 9A is opened and the upper end is expanded laterally and formed the conical surface, and base portion has the collar flange 9a with warm water water tank 9 one, is formed with through hole 9b at the base portion of the formed protuberance 9c of central part.This through hole 9b is set as, the inside of the guiding tube 9d cylindraceous that hangs down in being communicated in from from the central part of water inlet 9A to warm water water tank 9.
Therefore, the make-up water that is supplied to water inlet 9A flow in the guiding tube 9d via described through hole 9b, thereby make-up water is supplied to from the peristome towards the bottom surface of warm water water tank 9 of this guiding tube 9d.Owing to consisting of by this way, therefore be stranded in upper layer part in the warm water water tank 9, be implemented thermoregulator warm water and can not mixed with the lower make-up water of temperature, thereby the warm water that can suit to the nozzle unit supplying temperature.
Upper side at described warm water water tank 9 possesses effuser 9e, thereby can realize the outflow of warm water outside warm water water tank 9 that be warmed by electric heater 10.As shown in figure 10, this effuser 9e also can be arranged on the place, centre position of warm water water tank 9.By this way, because by effuser 9e being arranged on the place, centre position of warm water water tank 9, thereby the warm water that is stranded in the upper strata of effuser 9e can be used in flushing, therefore even carry out work and informed in the warm hydropenic situation at described float switch 11, also can utilize the described warm water that is stranded in the upper strata to implement for several times flushing, thereby can prevent in the generation of informing the unfavorable condition that warm hydropenic while washing capacity stops.
In addition, in the present invention, in the structure of portable toilet 1, be made as water tank 20 described later is configured in state on the warm water water tank 9, and make the collar flange 20a of feed water inlet 20A of the collar flange 9a of water inlet 9A of warm water water tank 9 and water tank 20 chimeric, but this moment, the hydrostatic pressure of the make-up water in the water tank 20 concentrates on 20A place, feed water inlet.Therefore, in order to tackle this hydrostatic pressure, and in the base portion of collar flange 9a week configuration liner 13, when the collar flange 22a of the lid 22 that water tank 20 has been installed, the top of this collar flange 22a is pressed liner 13 and is obtained liquid-tight state, thereby prevents the leakage of make-up water.
For to nozzle unit NU pressurized delivered warm water, the suction tube 14a of the effuser 9e of the warm water water tank 9 that consists of by this way and the pump unit 14 that consists of by sundstrand pump (gear pump) and motor, be connected by flexible pipe 15, on the other hand, bleed pipe 14b is connected with flushing water switch unit SU by flexible pipe 16 too.Two flexible pipes 18,19 are connected in nozzle unit NU from this flushing water switch unit SU.In addition, flexible pipe 18 is supplied with warm water to the private parts flooding nozzle side of nozzle unit NU, and flexible pipe 19 is supplied with warm water to buttocks flooding nozzle side.
Next, the structure of water tank 20 is elaborated.Water tank 20 is, for example by synthetic resin is carried out the ducted body that blow molding forms, and possesses the negative pressure relief valve 21 of eliminating for the negative pressure that will produce along with the minimizing of make-up water.Shown in Fig. 6 (A), Fig. 6 (B), negative pressure relief valve 21 shown in Figure 5 becomes following structure, that is, on helical spring 21a, be mounted with steel ball 21b and be incorporated in structure in the casing, and the casing above this steel ball 21b is formed with passage 21c, 21e.
Because negative pressure relief valve 21 of the present invention consists of in as above this mode, therefore under the state that as shown in Figure 5 water tank 20 has been connected on the warm water water tank 9, shown in Fig. 6 (A), helical spring 21a shrinks downwards owing to the weight of steel ball 21b, thereby passage 21c becomes the state of opening.Thus, the inside of warm water water tank 9 becomes identical with the air pressure of outside, thereby can prevent the generation of negative pressure.On the other hand, when taking off water tank 20 from warm water water tank 9, and be in the mode of below when spinning upside down with pressure relief valve 21, shown in Fig. 6 (B), thereby the restoring force steel ball 21b by helical spring 21a is pressed to the direction of passage 21c, and by liner 21d and sealed, thereby passage 21c is closed.Thus, water tank 20 becomes liquid-tight state, thereby even overturn and carry from state shown in Figure 5, the situation that the make-up water in the water tank 20 leaks also can not occur being encased in.
The structure of the feed water inlet 20A of described water tank 20 is formed with threaded-on flange 20a in its bottom with the state outstanding to the outside, and possesses the lid 22 of being combined with this threaded-on flange 2Oa screw thread as shown in figure 11.This lid 22 possesses from tabular surface and to extend the collar flange 22a that arranges, and this collar flange 22a is embedded among the collar flange 9a of water inlet 9A of described warm water water tank 9.In addition, at the central part place of described tabular surface, be formed with the bearing portion 22c of through hole 22b around possessing, and accept flange 22d to be formed with valve around the mode of the periphery of described through hole 22b.
In described bearing portion 22c, insert and be installed with axle 23, and be provided with the tight cut-off valve 24 that engages of peristome of accepting flange 22d with described valve on the top of this axle 23.On the other hand, between the flange 23a of the end of bearing portion 22c and axle 23, be provided with compression helical spring 25, and direction from flange 22d to blocking valve that accept is to cut-off valve 24 application of forces.
Namely, under state shown in Figure 11, axle 23 is also boosted with the protuberance 9c butt of the water inlet 9A of warm water water tank 9, and cut-off valve 24 makes valve accept the peristome opening of flange 22d thus, thereby can realize that the make-up water of water tank 20 is to the inflow of warm water water tank 9.When under related state, when water tank 20 is broken away from from warm water water tank 9, compression helical spring 25 will play a role and axle 23 is descended, thereby cut-off valve 24 blocking valves are accepted the peristome of flange 22d, have stoped thus the outflow of make-up water.
In addition, when water tank 20 was broken away from from warm water water tank 9, residual in the collar flange 22a of the lid 22 of water tank 20 had make-up water, thereby this make-up water leaks in the collar flange 9a of warm water water tank 9 when breaking away from.For the make-up water that prevents effectively this leakage further to the situation of warm water water tank 9 external leakages, only need to get final product in the following way, namely, the collar flange 9a of warm water water tank 9 is set as far as possible the collar flange 22a of the lid 22 that is higher than water tank 20, heavy section 22e perhaps is set in collar flange 22a as shown in Figure 11, thereby makes the spatial content of collar flange 22a inside compare less with the spatial content of the collar flange 9a inside of warm water water tank 9.
In the water tank 20 of above structure, peristome stickup at collar flange 22a arranges liner 26, and paste in the par of corresponding with it lid 22 liner 27 is set, come the flange of the filter 28 that clamping installs by two liners 26,27, thereby prevent the leakage of make-up water.In addition, when water tank 20 being implemented make-up water additional, spin upside down by the water tank 20 that will break away from, and the screw thread that lid 22 is rotated to remove between threaded-on flange 20a is combined, taking out filter 28, thereby can implement the water filling from the peristome of threaded-on flange 20a.In addition, by in this filter 28, enclosing bacteria remover in advance, thereby can implement the degerming to make-up water.
As indicated above, the deficiency of the warm water in the warm water water tank 9 can detect by float switch 11, below, when not enough to the make-up water in water tank 20, the structure that this situation is detected describes.As shown in Figure 5, at the bottom of water tank 20 configuration floating unit 29.In the inside of this floating unit 29, be provided with the buoy 29a that the water level with the water surface of make-up water synchronously carries out lifting, and be provided with alnico magnets 29b at this buoy 29a.On the other hand, in warm water water tank 9 sides, and the casing 31 that each structural element is taken in, with the floating unit 29 opposed back sides magnetic induction part 30 is set.
By consisting of by this way, thereby the make-up water in water tank 20 is consumed; buoy 29a and alnico magnets 29b are when descending with the synchronous mode of the reduction of the water level of this make-up water; the impact that gives the magnetic force of magnetic induction part 30 will increase gradually, thereby can obtain the signals of telecommunication from this magnetic induction part 30.When the signal of telecommunication that obtains from magnetic induction part 30 has surpassed threshold value, can light indicator to inform the deficiency of make-up water by the processing of the electronic circuit in the control part 91 described later or by the conducting cut-off signal of lead-in wire switch, a plurality of indicators are lighted successively continuously, thereby made the not enough degree of make-up water visual.
In addition, in situation about consisting of in the mode of metered injection in once flushing (approximately 500cc) warm water, for example, identifying in the situation of demonstration by indicator take flushable number of times as last twice or last mode, when the signal of telecommunication of exporting, obtaining from magnetic induction part 30 when the warm water surplus corresponding to twice amount has surpassed the threshold value of setting, indicator (LED81) is lighted.And, when under this state, implementing flushing, thereby when having surpassed the threshold value of setting corresponding to the signal of telecommunication that the warm water surplus of amount is once exported, obtained from magnetic induction part 30, make the indicator flicker.So, light, glimmer and identify demonstration by making indicator, thereby can inform definitely the deficiency of make-up water, can effectively arouse user's attention thus.In addition, the identification demonstration of being undertaken by indicator is not limited to light, glimmer, and also can make glow color different.
Although above-mentioned example has adopted, set the mode of the threshold value in two stages with respect to the signal of telecommunication that obtains from magnetic induction part 30, but in the situation that implement by the lead-in wire switch, also can make by the following signal of telecommunication indicator light or glimmer, the described signal of telecommunication is, arrives the lead-in wire switch that carries out work when being the corresponding position of last twice warm water surplus with flushable number of times by the alnico magnets 29b at floating unit 29, with arrive the signal of telecommunication that obtains to the lead-in wire switch that carries out work with flushable number of times during for the corresponding position of last warm water surplus at alnico magnets 29b.
In addition, because the detection of warm water surplus also can be by detecting to implement to the hydraulic pressure in the warm water water tank 9, therefore as shown in Figure 10 at the warm water water tank 9 interior pressure sensors 17 that arrange, and by this pressure sensor 17 hydraulic pressure in the warm water water tank 9 is detected.That is, when hydrostatic pressure reduces along with the minimizing of the make-up water in the water tank 20, the hydraulic pressure in the warm water water tank 9 also will reduce.Therefore, be the corresponding hydraulic pressure of last twice warm water surplus when pressure sensor 17 detects with flushable number of times, thereby when its signal of telecommunication has surpassed the threshold value of setting, indicator lighted.And when implement flushing under this state, pressure sensor 17 detects the hydraulic pressure corresponding with the warm water surplus of once measuring, thereby when the signal of telecommunication has surpassed the threshold value of setting, makes indicator glimmer to inform the deficiency of make-up water.In addition, the pressure sensor 17 that is arranged in the warm water water tank 9 is not limited to be arranged on the inwall of warm water water tank 9, can suitably select to be arranged near through hole 9b etc. of guiding tube 9d.
Although in above embodiment, respectively to last twice amount and once the amount the warm water surplus detect, but also can be in the following way, namely, when having implemented flushing when the warm water surplus that is detecting twice amount after indicator is lighted, pump unit 14 is driven control spraying and once to measure the warm water of suitable amount and make the indicator flicker, thereby inform that the warm water surplus is residue amount once.In addition, although used the indicator that consists of by LED as informing the unit, but also can adopt following structure, namely, carry liquid crystal indicator, and come structure that the user is informed by display case on liquid crystal indicator such as the literal of " remaining amount once " or " remaining twice amount " and so on.
Next, the example of the warm water washing unit that adopts in the portable toilet of the present invention described.To shown in Figure 16, warm water washing unit 40 consists of by nozzle unit NU and flushing water switch unit SU such as Figure 12, and wherein, described nozzle unit NU possesses: buttocks flooding nozzle 41; Private parts flooding nozzle 42; The buttocks flooding nozzle moves with nozzle body 43, its advance and retreat of implementing buttocks flooding nozzle 41; Private parts flooding nozzle nozzle body 44, it implements the advance and retreat action of private parts flooding nozzle 42, described flushing water switch unit SU possesses transfer valve 46, and the warm water which supplies with the warm water water tank 9 that is supplied to by pump unit 14 in described transfer valve 46 subtend buttocks flooding nozzles 41 or the private parts flooding nozzle 42 is selected.
In nozzle unit NU, with private parts flooding nozzle 42 almost parallel ground be positioned at buttocks flooding nozzle 41 under mode, the buttocks flooding nozzle that described buttocks flooding nozzle 41 and private parts flooding nozzle 42 is accommodated in configured in parallel up and down with nozzle body 43 and private parts flooding nozzle with in the nozzle body 44.As described later, buttocks flooding nozzle 41 and private parts flooding nozzle 42 implement to stretch out action by the pressurization to warm water of being undertaken by pump unit 14, and spray warm water from nozzle bore 41a, the 42a of top ends.Buttocks nozzle for rinsing housing 43 and private parts nozzle for rinsing housing 44 are by synthetic resin and by integrally formed.
Be provided with warm water introduction part 43b and warm water introduction part 44b at the rearward end place of nozzle unit NU, wherein, the warm water that described warm water introduction part 43b supplies with from flushing water switch unit SU with nozzle body 43 guiding to the buttocks flooding nozzle, the warm water that described warm water introduction part 44b supplies with from flushing water switch unit SU with nozzle body 44 guiding to the private parts flooding nozzle.Particularly, warm water introduction part 43b, 44b are formed on the introduction part cover 46, and installing component 67 are installed on the rear end of nozzle unit NU with bolt 68 in the mode that covers this introduction part cover 46.Thus, the buttocks flooding nozzle becomes the state that is communicated with warm water introduction part 43b with the entrance opening of the rear end of nozzle body 43, and in addition, the private parts flooding nozzle becomes the state that is communicated with warm water introduction part 44b with the entrance opening of the rear end of nozzle body 44.
So, the buttocks flooding nozzle 41 of configuration and private parts flooding nozzle 42 be with in the space of pedestal 2 up and down, the mode of all advancing and retreat below tiltedly towards the place ahead and configuring, thereby become pedestal 2 about between center line and the configuration on the center line of fore-and-aft direction.Therefore, can be rinsed the part for the anus that is seated at the people on the toilet seat 7 or private parts etc., and obtain under or just lower after the warm water of quadrate part spray.
Therefore, under the state to the pressurization of warm water of not implementing to be undertaken by pump unit 14, buttocks flooding nozzle 41 is by helical spring 45a, and be retained as retreat to the buttocks flooding nozzle with the state in the nozzle body 43, when the pressurization of having implemented to warm water, the water carrier 41b that is formed at the collar flange on the rear end of buttocks flooding nozzle 41 bears this pressurization, and helical spring 45a is compressed, thereby buttocks flooding nozzle 41 is stretched out, and be installed in liner 41p on the water carrier 41b and buttocks flooding nozzle with the retainer 43a butt in the nozzle body 43, thereby stop at predetermined extended position place.

Next, the portable toilet of the present invention 1 incidental functional imperative that consists of is in the above described manner described.Toilet seat 7 is set to, and can open and close at above-below direction by motor 71, in addition also is provided with deodorizing unit 72 and drying unit 73.In addition, in described toilet seat 7, dispose the heater that is insulated covering by aluminium foil at its back side, toilet seat 7 is heated by this heater.
As such shown in the usefulness enlarged drawing among Figure 17, for the operating portion 80 that above-mentioned each functional imperative and nozzle unit NU are moved, dispose various console switch and LED display part.As this console switch, be provided with the warm water temperature by-pass cock 86 of flow of water increase and decrease switch 85a, 85b, warm water water tank 9 of buttocks flushing beginning switch 83, private parts flushing beginning switch 84, flushing shutdown switch 82, flushing water and the toilet seat temperature regulation switch 87 that the temperature of toilet seat 7 is changed etc.
In addition, as the LED display part, be provided with LED85c, LED86a, LED87a, wherein, described LED85c is corresponding to flow of water increase and decrease switch 85a, 85b and represent the persistent erection of the flow of water with three phases a little less than, described LED86a represents warm water temperature corresponding to warm water temperature by-pass cock 86 and with high this three phases in low, and described LED87a represents the toilet seat temperature corresponding to toilet seat temperature regulation switch 87 and with high this three phases in low.In addition, also possess LED81, described LED81 is when the make-up water of the warm water of warm water water tank 9 or water tank 20 is not enough, according to lighting from the signal of float switch 11 or magnetic induction part 30.In addition, switch 99a, 99b that motor 71 is opened and closed also are arranged on the operating portion 80, and described motor 71 opens and closes toilet seat 17 on above-below direction.
Figure 18 is, expression is as the figure of the structure of the control circuit 90 of control module, and the control part 91 that will consist of take microcomputer as main body is connected on the industrial AC power AC, and operating portion 80 is connected on this control part 91.And, be connected with the switch 92 of taking one's seat, temperature sensor 93, float switch 11 or magnetic induction part 30 and thermistor 12 at this control part 91, wherein, described switch 92 the taking one's seat of subtend toilet seat 7 of taking one's seat are detected, the temperature of 93 pairs of toilet seats 7 of described temperature sensor detects, and the temperature of the warm water in 12 pairs of warm water water tanks of described thermistor 9 detects.The described switch 92 of taking one's seat adopts following switch, that is, the situation that the weight when sitting on the toilet seat 7 according to toilet seat 7 because of the people descends is slightly carried out the switch of work or the infrared switch that the people who is seated on the toilet seat 7 detected by infrared ray etc.
The control mode of described control part 91 for realizing by microcomputer, described microcomputer possesses timer, memory etc., and the action of implementing to be scheduled to according to predefined program.In addition, on described industrial AC power AC, and on according to the switch element 94a～94g that moves separately from the output signal of control part 91, the warm water heater 10 that is connected with toilet seat heater 95, the water in the warm water water tank 9 are heated, the motor 47 that transfer valve 46 is driven, motor 71, deodorizing unit 72, drying unit 73 and pump unit 14 that toilet seat is opened and closed.
Under the holding state that makes 91 work of above-mentioned control circuit, usually, contact disconnects when being in the abnormal temperature of closed temperature detecting part 96 in detecting warm water water tank 9, thereby blocks to the energising of warm water heater 10.In addition, for the water in the warm water water tank 9, the work of the control part 91 that is undertaken by the temperature sensing based on thermistor 12, thereby switch element 94b implements the conducting (ON) of the energising of warm water heater 10/disconnection (OFF) action, and then the temperature of warm water is maintained in the predetermined temperature range.
In addition, under holding state, in transfer valve 46, liner 63a, the 63b butt of the face beyond its valve passage 46a and the ingress edge of buttocks flushing water passage 51 and private parts flushing water passage 52, thus, transfer valve 46 stops up the entrance of buttocks flushing water passage 51 and private parts flushing water passage 52, so that warm water water tank 9 all is not communicated with any one party in buttocks flushing water passage 51 and the private parts flushing water passage 52, and valve passage 46a all is not communicated with any one party in buttocks flushing water passage 51 and the private parts flushing water passage 52, thereby is in the state of blocking.
Under this holding state, control part 91 makes motor 71 work by switch element 94d is worked, thereby toilet seat 7 is opened upward.And, when detecting the people to the taking one's seat of toilet seat 7 by the switch 92 of taking one's seat, thereby make the work of switch element 94e energising beginning deodorizing unit 72.When under this takes one's seat state, buttocks flushing beginning switch 83 is pressed and has sent that buttocks flushes instructions or private parts flushing beginning switch 84 are pressed and when having sent the private parts flushes instructions, thereby control part 91 will make the suitable work of switch element 94c by the driving of motor 47 transfer valve 46 be rotated, thereby and switch element 94g work be driven to pump unit 14.Thus, the warm water to warm water water tank 9 aspirates via flexible pipe 15 in pump unit 14, and will aspirate and pressurized warm water is supplied with to flushing water switch unit SU via flexible pipe 16.
In this case, when buttocks flushing beginning switch 83 is pressed, work by motor 47 make transfer valve 46 with the state of liner 63a, 63b and butt parts 65a, 65b butt under rotate, and under the valve passage 46a of transfer valve 46 and state that buttocks flushing water passage 51 is communicated with, motor 47 is stopped.Thus, pressurized and supply to warm water in the valve chamber 49 by pump unit 14, flow through valve passage 46a and buttocks flushing water passage 51, and flow through flexible pipe 19 and flow into to the warm water introduction part 43b of nozzle unit UN from the 51a of export department of buttocks flushing water passage 51.
The described Water Pressure of the warm water among the warm water introduction part 43b that flow into is on the water carrier 41b of the buttocks flooding nozzle 41 that is in going-back position owing to helical spring 45a, thereby helical spring 45a is compressed and buttocks flooding nozzle 41 is stretched out, thereby and liner 41p and retainer 43a butt this stretch out and stop.So, in the position that buttocks flooding nozzle 41 stretches out and stops, pass the centre bore of water carrier 41b and flow among the inner passage 41t of buttocks flooding nozzle 41 as the warm water of flushing water, thereby and can implement the buttocks flushing from the nozzle bore 41a ejection on top.
And, flushing shutdown switch 82 is pressed, control part 91 work, thus make switch element 94c carry out work so that motor 47 is driven, make thus transfer valve 46 be back to position of readiness, and make switch element 94g carry out work to stop the driving to pump unit 14.Thus, because the pressurization to the warm water that aspirates from warm water water tank 9 is no longer implemented in pump unit 14, therefore the ejection from the warm water of nozzle bore 41a stops, and by helical spring 45a buttocks flooding nozzle 41 is reverted to retreat to the buttocks flooding nozzle with the state in the housing 43.
On the other hand, when private parts flushing beginning switch 84 is pressed, work by motor 47 make transfer valve 46 with the state of liner 63a, 63b and butt parts 65a, 65b butt under rotate, and under the state that the valve passage 46a of transfer valve 46 has been communicated with private parts flushing water passage 52, motor 47 is stopped.Thus, pressurized and supply to warm water in the valve chamber 49 by pump unit 14, flow through valve passage 46a and private parts flushing water passage 52, and flow through flexible pipe 18 and flow into to the warm water introduction part 44b of nozzle unit NU from the 52a of export department of private parts flushing water passage 52.
The described Water Pressure of the warm water among the warm water introduction part 44b that flow into is on the water carrier 42b of the private parts flooding nozzle 42 that is in going-back position owing to helical spring 45b, thereby helical spring 45b is compressed and private parts flooding nozzle 42 is stretched out, thereby and liner 42p and retainer 44a butt this stretch out and stop.So, in the position that private parts flooding nozzle 42 stretches out and stops, pass the centre bore of water carrier 42b and flow among the inner passage 42t of private parts flooding nozzle 42 as the warm water of flushing water, thereby and can implement the private parts flushing from the nozzle bore 42a ejection on top.
And flushing shutdown switch 82 is pressed, control part 91 work, thus make switch element 94c carry out work so that motor 47 is driven, make thus transfer valve 46 return position of readiness, and make switch element 94g work to stop driving to pump unit 14.Thus, because the pressurization to the warm water that aspirates from warm water water tank 9 is no longer implemented in pump unit 14, therefore the ejection from the warm water of nozzle bore 42a stops, and by helical spring 45b private parts flooding nozzle 42 is reverted to retreat to the private parts flooding nozzle with the state in the housing 44.
As described above in detail, although in portable toilet 1 of the present invention, be set as, implement pressurization to warm water by pump unit 14, described pressurization to warm water is used for implementing stretching out of buttocks flooding nozzle 41 and private parts flooding nozzle 42, and warm water is from nozzle bore 41a, the ejection of 42a, but as shown in figure 21, owing to being configured in the action of hydrostatic pressure of the make-up water in the water tank 20 on the warm water water tank 9 in the warm water of warm water water tank, therefore this warm water becomes the state that is biased all the time, thereby can under the condition that ability of pump unit 14 is not increased to more than the required degree, obtain the function as purpose.In addition, although be illustrated according to the embodiment that stretches out that implements buttocks flooding nozzle 41 and private parts flooding nozzle 42 by the pressurization of the 14 pairs of warm water in pump unit, but also can be in the following way, namely, this pressurization only is used for the injection of warm water, and implements the advance and retreat of buttocks flooding nozzle 41 and private parts flooding nozzle 42 by motor.
In addition, owing to not adopting the existing method of drawing make-up water from water tank, therefore need not water tank is arranged feed pipe, water tank is become easily from the dismounting of warm water water tank, thereby make the complement operation of make-up water become simple.And, because in portable toilet of the present invention, be provided with the unit that the minimizing to make-up water in the minimizing of warm water in the warm water water tank or the water tank detects, therefore can inform definitely the additional opportunity of make-up water.
As indicated above, although can be according to the informing of additional opportunity of the detection of implementing the warm water surplus from the signal of magnetic induction part, lead-in wire switch, pressure sensor and make-up water, use this signal can realize as problem of the present invention function, be the detection of hydrostatic pressure of make-up water and the change to the driving force of pump unit of carrying out according to this hydrostatic pressure.Below, Figure 20 of the flow process of Figure 19 of the mode of the control of reference expression pump unit 14 and the control of expression pump unit describes the example that has adopted pressure sensor 17.
In the present invention, pump unit 14 adopts dc motors, by applying voltage control mode or PWM(Pulse Width Modulation: pulse width modulation) control mode etc. and this dc motor is driven control.As shown in figure 19, the benchmark of this driving control is set to, when the size (surplus of=make-up water) of the hydrostatic pressure when having been replenished to greatest extent make-up water in the water tank 20 is ST1, the driving force of pump unit 14 is made as SP1 and it is defined as benchmark, and as the starting point of controlling beginning.That is, in programme controlled flow process shown in Figure 20, at first, judge the action (Sa1) that has or not pressure sensor 17, when not from pressure sensor 17 picked up signal, the hydrostatic pressure that is in make-up water does not act on the state of warm water water tank 9, does not dispose water tank 20 thereby be judged as.
When under related state, in the time of will being configured on the warm water water tank 9 with the water tank 20 that has been added to greatest extent make-up water, because the action of hydrostatic pressure of make-up water is in warm water water tank 9, pressure sensor 17 detects hydrostatic pressure ST1(Sa2) therefore and output, utilized the driving force SP1 of pump unit 14 application of force, minimum of hydrostatic pressure ST1 that should maximum by initial setting.But, might not supply with to greatest extent make-up water in the water tank 20, can suppose that the water tank 20 that has replenished to have reduced a certain proportion of mode from maximum magnitude of recruitment is configured in the state on the warm water water tank 9.But, owing in treatment S a2, implementing the processing that the convection cell static pressure detects, therefore when disposing water tank 20, with the hydrostatic pressure ST2 that detects corresponding to the amount of the make-up water that is replenished, and come the driving force SP2 of initial setting pump unit 14 according to this hydrostatic pressure ST2, thereby can avoid following in the magnitude of recruitment of make-up water and the problem that produces.
When implementing by this way initial setting, and the injection of warm water from nozzle is set as in the situation of metered injection mode, when having confirmed the execution of flushing (Sa3), improves the driving force (Sa4) of pump unit 14.Meanwhile, test fluid static pressure in treatment S a2 again, and according to judging that from the signal of pressure sensor 17 whether washing time is last twice (Sa5), when washing time does not reach last twice, is transferred to the holding state for the treatment of S a3.
And, owing to when repeating to implement to wash, all repeating to implement above-mentioned processing, judgement at every turn, therefore the driving force of pump unit 14 few along with make-up water De Minus, be the reduction of hydrostatic pressure and progressively improving, thereby no matter the surplus of make-up water what, warm water all becomes fixing from the spray regime of nozzle.Proceed by this way flushing, when being judged as flushable number of times and being last twice (Sa5), light warning lamp (Sa6), and be transferred to holding state.And, when having carried out flushing in twice the situation in the end, be judged as flushable number of times and be last (Sa7), at this moment, make warning lamp flicker (Sa8), and stop washing capacity.
According to above explanation as can be known, by arrange in the inside of water tank with water tank in the detected element that moves up and down of the synchronous mode of the water surface site of make-up water, on the other hand, the arranged outside of the water tank on the above-below direction of this detected element is to the approaching detecting element that detects of detected element, perhaps in the inside of warm water water tank pressure sensor is set, thereby can be according to described detecting element or the detected signal of telecommunication of pressure sensor, and to come flushable number of times by indicator be that last twice and last situation are identified demonstration.
In addition, even reduce owing to repeatedly washing the make-up water that makes water tank 20, also can be set as fixing from the spray regime of nozzle warm water, therefore can avoid reducing because of the most important function in the portable toilet generation of the problem that causes, thus implement in the time of often can obtaining smoothly flushing processing etc., the peculiar effect of the present invention.
Such as mentioned above, the first mode of the present invention is a kind of portable toilet, it arranges Warm water flushing toilet seat in the section of taking one's seat, and the excrement-collecting pallet is set below this Warm water flushing toilet seat, and rear side configuration water tank and warm water water tank at backrest, in described portable toilet, water tank has been configured to described warm water water tank above the time, the feed water inlet of this water tank is connected with the water inlet of warm water water tank, thereby the action of hydrostatic pressure of the make-up water of water tank is in the warm water of warm water water tank.
In addition, in above-mentioned the first mode, adopt the mode that the negative pressure relief valve is set at water tank, and arrange and when making water tank from the disengaging of warm water water tank and upset, to stop the negative pressure relief valve of the leakage of make-up water.
The second mode of the present invention is a kind of portable toilet, it arranges Warm water flushing toilet seat in the section of taking one's seat, and the excrement-collecting pallet is set below this Warm water flushing toilet seat, and rear side configuration water tank and warm water water tank at backrest, in described portable toilet, when water tank has been configured to the top of described warm water water tank, the feed water inlet of this water tank is connected with the water inlet of warm water water tank, thereby the action of hydrostatic pressure of the make-up water of water tank is in the warm water of warm water water tank, the pump unit that warm water to described warm water water tank aspirates is set, by this pump unit to nozzle unit pressurized delivered warm water, hanging down towards the inside of warm water water tank from the central part of the water inlet of described warm water water tank arranges guiding tube, and the make-up water of the water tank that flows into from the top ends of this guiding tube is flowed out from the bottom towards the bottom surface of warm water water tank.
