In other words, when voltage vcc was supplied with input In, microcomputer 10 produced a low level signal by output Out.
When the output Out by microcomputer 10 produces a low level signal, stop electric current to flow through change-over switch IC1 by relay R Y, therefore by applied voltage Vcc, relay R Y interrupt run, relay switch RY-b disconnects, the power supply of cut-out pressure pump 3, and compression pump 3 is out of service.
When the voltage vcc that provides by means of input In was cut off, microcomputer 10 produced a high level signal, starting relay RY thus through output Out.
When relay switch RY-b connects, give compression pump 3 power supplies, make it start operation.
In other words, when water service is ended, water cut sense switch SW1 disconnection, compression pump 3 is out of service, prevents compression pump 3 idle running like this and causes damage.
Yet, there is a problem in the above-mentioned water purifier, when moving, water purifier surpasses predetermined time interval, and preprocessor 1 and reverse osmosis filter 5 can stop up, and have hindered carrying out smoothly of water treatment procedure.
Also we can say, have such problem, when filter stops up and compression pump 3 when being forced to move, compression pump 3 is damaged and shorten the life-span.
In order to address the above problem; the object of the present invention is to provide a kind of water purifier pressure pump control apparatus, whether the filter that it can detect water purifier blockage phenomenon, so that stop the operation of compression pump; when filter stops up, can protect compression pump thus.
Another object of the present invention is to provide a kind of pressure pump control apparatus of water purifier, and whether can detect filter by it has clogging, and when filter stops up, can notify the user.
According to purpose of the present invention, a kind of pressure pump control apparatus is provided, this device comprises:
Be used for detecting the detection part whether filter be connected with two ends of compression pump (tip ends) respectively stops up;
Be used for output, power supply (powersupply) parts of the running current of supply or cut-out pressure pump according to detection part.
According to the output of detection part, the display unit of the replacement time of notice user filtering device.
Therefore, when filter stopped up, compression pump was out of service, had so promptly protected compression pump, can notify the user that clogging has taken place again.
Feature for a more complete understanding of the present invention and purpose, below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the system block diagram of conventional water purifier;
Fig. 2 is the circuit diagram of the pressure pump control apparatus of prior art;
Fig. 3 is the circuit diagram of water purifier pressure control device of the present invention;
According to the present invention, pressure pump control apparatus comprises: current detection sensor (sensor) 20, power supply unit 30 and display unit 40.
Numbering R1 and R2 are bias resistances, and D1 and D2 are Zener diodes, and SW1 is the water cut sense switch.
In the pressure pump control apparatus of above structure, current detection sensor 20 is used for the running current of detected pressures pump 3, to produce one and the proportional magnitude of voltage of running current.
The magnitude of voltage that power supply unit 30 is exported according to current detection sensor 20, the running current of supply or cut-out pressure pump 3.
In above-described power supply unit 30, when the magnitude of voltage of supplying with current detection sensor 20 departs from a normal voltage value, microcomputer 50 will produce a low level signal to change-over switch IC1 by output Out2, and the voltage vcc of sever supply relay R Y, therefore, relay R Y interrupts making the power supply of compression pump 3 to cut off.
The effect of display unit 40 is, according to the output voltage values of current detection sensor 20, notifies the replacement time of user filtering device.
In above-described display unit 40, when the magnitude of voltage of supplying with current detection sensor 20 departs from a normal voltage value, microcomputer 50 will produce a high level signal to change-over switch IC2 by output Out1, and voltage vcc is supplied with LED, thus, make LED luminous.
The following describes the operational effect of the pressure pump control apparatus of water purifier of the present invention.
When compression pump 3 started, the hydraulic pressure of the filter that its running current will be connected with 3 two ends of compression pump raise pro rata or reduces.
As an example, if the scope of compression pump 3 running current values is in 1-10, when the pretreatment filters that links to each other when the front end with compression pump 3 is stopped up, the running current value of compression pump 3 is in the 1-2 scope, when the reverse osmosis filter that is connected with the rear end (rear end) of compression pump 3 stopped up, the running current value of compression pump 3 raise in the 8-9 scope.
In addition, when pretreatment filters and not obstruction of posttreatment filter, the running current value of compression pump 3 is in the 4-6 scope.
The running current value of compression pump 3 is along with the changed condition of filter, and detects with current detection sensor 20.In order to make the signal and the running current value that are added to microcomputer 50 proportional, so supply microcomputer 50 is 0 to 5V voltage signal.
