[specific embodiment]
See also Fig. 1 to shown in Figure 5, the water-saving toilet of the utility model control discharging quantity of water comprises water tank 1, be installed on water tank 1 side on the lower side the position flush valve 2, be installed on water tank 1 side on the upper side the position inlet valve 3, place the pressure sensor 4 of water tank 1 inner bottom part, and place the control system that water tank is outside and link to each other with above-mentioned flush valve 2, inlet valve 3, pressure sensor 4.
What described flush valve 2 and inlet valve 3 adopted is the bistable electromagnetic valve, when adding forward voltage, and the magnet adhesive of electromagnetic valve inside, valve open, water tank water intake or bath; When electromagnetic valve added backward voltage, the electromagnetic field of generation was opposite with the magnetic direction of inner magnet, and closed electromagnetic valve stops into water or bath.
Described pressure sensor 4 is a liquid level sensor, its output signal is 4-20mA, and operating voltage is 24V, is positioned over water tank 1 bottom, in order to detecting the hydraulic pressure in the water tank, and this pressure value is converted to the signal of telecommunication feeds back to single-chip microcomputer in hereinafter described the control system.
See also shown in Figure 4, described control system is closed in the box, the box outside is provided with power interface, sensor interface, inlet valve interface, and the flush valve interface, and aforementioned flush valve is connected by the interior interlock circuit of above-mentioned interface and control system with inlet valve.
Below, please consult shown in Figure 3ly especially, specifically introduce the control system of the utility model water-saving toilet:
Control system comprises power circuit, the single-chip microcomputer that links to each other with power circuit, the inlet valve control circuit that links to each other with single-chip microcomputer respectively, flush valve control circuit, keyboard circuit, and holder.
As shown in Figure 3, when the pin P20 and the P23 of single-chip microcomputer are low level, when P21 and P22 are high level, triode Q7 and Q10 conducting, triode Q1 and Q9 end, and so, inlet valve J two ends add forward voltage, the magnet adhesive that it is inner, the electroceramics valve open begins water inlet in the water tank; On the contrary, when the pin P20 and the P23 of single-chip microcomputer are high level, when P21 and P22 were low level, triode Q7 and Q10 ended, triode Q1 and Q9 conducting, so, electromagnetic valve J two ends add backward voltage, and the electromagnetic field of its generation is opposite with the magnetic direction that magnet forms, so, electromagnetic valve is closed, and stops into water in the water tank.
Similar to the inlet valve control circuit, for the flush valve control circuit, when the pin P10 and the P16 of single-chip microcomputer are low level, when P12 and P11 are high level, triode Q8 and Q12 conducting, triode Q6 and Q11 end, at this moment, the flush valve two ends add forward voltage, the magnet adhesive in it, flush valve is opened, and water tank begins to wash by water in toilet; On the contrary, when the pin P10 and the P16 of single-chip microcomputer are high level, when P12 and P11 are low level, triode Q8 and Q12 kidnap, triode Q6 and Q11 conducting, this moment the flush valve two ends add backward voltage, the electromagnetic field of its generation is opposite with the magnetic direction that magnet forms, so electromagnetic valve is closed, stop bath in the water tank.
Keyboard circuit links to each other with holder with single-chip microcomputer.
Holder in the utility model water-saving toilet, adopts electric erasable memory body only able to programme (Electrically-Erasable Programmable Read-Only Memory, EEPROM or E
2PROM), this holder can guarantee that after outage the data that are stored in this holder can not lost.
Described control system is closed in the box of a sealing, and be installed in certain permanent position of toilet outside, for example on the wall, a surface of this box is a control panel, as shown in Figure 4, this control panel is provided with the LED display lamp whether display power supply is connected, and shows the display screen of related data, and four gauge tap S1, S2, S3 and S4.
Described switch S 1 is provided with switch for parameter, when pressing this switch for the first time, switch S 1 closure of correspondence after single-chip microcomputer is read this signal, is read the parameter value of initial default on the keyboard circuit from holder, and be presented on the charactron, at this moment, the user need be provided with first parameter that meets own demand by switch S on the control panel 2 and S3, presses switch S 4 after setting is finished, thereby single-chip microcomputer indication holder is preserved this first parameter value.
After finishing above-mentioned action, the user then is provided with second parameter, after setting is finished, presses switch S 4 again, thereby finishes the preservation to second parameter.
After switch S 2 and S3 are pressed respectively, promptly wash stool or the action of flushing urine under original state.
Before design the utility model water-saving toilet, at first need size, the water tank size of design toilet, the i.e. sectional area of water-closet tank and height according to discharging quantity of water.Suppose that the sectional area of water-closet tank is S, the height of water tank is H, the volume V=S*H of water tank then, and this volume V should be designed to greater than maximum discharging quantity of water.
The elemental height of supposing water in the water tank is H0, then pressure sensor is output as P0=ρ gH0, and the discharging quantity of water of setting the flushing stool is V1=S*H1, the height H 10=H0-H1 of water in the rear water box of then washing by water, pressure sensor is output as P1=ρ g (H0-H1), and these data are stored in the holder; The discharging quantity of water of setting flushing urine is V2=S*H2, the water height H 20=H0-H2 in the rear water box of then washing by water, and pressure sensor is output as P2=ρ g (H0-H2), and these data are stored in the holder.
Below, please in conjunction with illustrated in figures 1 and 2, when needing bath, on control panel, select corresponding option, for example, during the flushing stool, press switch S 2, at this moment, single-chip microcomputer becomes low level with the pin that switch S 2 links to each other by high level, then, single-chip microcomputer sends instruction, access the water supply volume V1 of flushing stool in the holder, simultaneously, the indication flush valve is opened, water tank 1 beginning is discharged water to toilet, in the process that constantly discharges water, the pressure sensor 4 that is positioned at water tank 1 bottom constantly detects the hydraulic pressure of water tank 1, when the hydraulic pressure in it detects water tank 1 equals P1, single-chip microcomputer indication flush valve is closed, stop to discharge water, indicate inlet valve to open simultaneously, begin water inlet, in the process of water inlet, when the hydraulic pressure in pressure sensor detects water tank 1 equals P0, then close inlet valve, stop into water.
When flushing urine, only need press urine switch S 3, access the discharging quantity of water of urine, other processes are identical with the flushing stool, do not repeat them here.
The above only is a kind of embodiment of utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual is claim of the present utility model and contains.
