Abstract
The invention discloses a water leakage detection circuit for a water purifier and relates to the technical field of control devices of water purifiers. Water leakage detection electrodes and a feedback circuit are added to the circuit of a conventional controller, and the water leakage detection electrodes are two independent metal electrodes arranged at the leaked water collection part in the water purifier. In case of water leakage, water covers the two electrodes to be short-circuited, and a short circuit signal is fed back to a control unit of the water purifier through the feedback circuit to enter a water leakage mode; the control unit sends a command to close a water inflow solenoid valve, a booster pump, a flush electromagnetic valve and the like to protect the water purifier and gives a corresponding sound and light alarm to prompt a user to maintain promptly so as to avoid accidents. Therefore, the service life of the water purifier is prolonged.
Description
Technical field
The present invention relates to the control device technical field of water purifier, relate in particular to the circuit whether a kind of inside for detection of water purifier leaks.
Background technology
Water purifier is also filtrator, as wastewater treatment.The water purifier said at ordinary times, generally refers to the minifilters of using as family.Water purifier, according to different cleaning principles and technique, can divide many types.Generally there are RO counter-infiltration, nanofiltration, ultra filtration membrane, essence filter etc.Water purifier all impurity that effectively iron rust, sandstone, colloid and the diameter in filtering water is greater than 5 microns; Grain active carbon filter core carbon has superpower absorption affinity, effectively chlorine residue in planar water, smells the chemical agents such as taste, heterochromatic, agricultural chemicals; Accurate activated carbon cartridge, can effectively remove bacterium in water, toxin, heavy metal etc.
Most of water purifier is to adopt resistance sieve work principle of filter progressive structure mode, by multi-stage filter core, be connected in series and form from beginning to end, filter core precision is arranged in order from low to high, to realize multi-stage filter core, share and hold back dirt, thereby reduce that filter core stops up and artificial blowdown, the number of times of unpicking and washing and extend the more cycle of renew cartridge.Also having a kind of new mentality of designing is application sub-prime circulation principle self-cleaning frame mode, its design philosophy is no longer to provide space as much as possible and receives dirt for hiding dirt, but take sub-prime principle, isolate sub-fraction clean water, allow as far as possible again the former water circulation stream that does as usual move up pollution is pulled away in time with current simultaneously, reach that Running water never becomes putrid.So both obtained purifying waste water, and can or not be not easy again in machine, to precipitate dirt, and avoided forming secondary pollution and greatly alleviate filter core loss, water quality better and safer is energy-conservation low charcoal again.Along with growth in the living standard, the universal of water purifier will be more and more wider, and the product of new technology is meeting people's demand better.
Existing water purifier, directly drink machine or water dispenser product does not have inner leakage inspector; do not have leakage inspector to have following deficiency: when machine leaks; cannot the situation of leaking be detected automatically in time and make the protection action of closing into water water route, cause machine breakdown.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of testing circuit that leaks of water purifier, whether described circuit leaks for detection of the inside of water purifier, if leaked, disconnects timely water route, prompting user of service on-call maintenance, prevent that mishap from occurring, the serviceable life of having improved water purifier.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of testing circuit that leaks of water purifier, it is characterized in that: first on the check-out console that the leak detecting electrode that leaks connects the positive pole of the first power supply, second on the check-out console that the leak detecting electrode that leaks connects the base stage of triode Q1 through resistance R 3, first detecting electrode and second that leaks leaks and detects motor and keep interval to arrange, and the positive pole of the first power supply is successively through capacitor C 2 and capacitor C 3 ground connection; The positive pole of second source connects the collector of triode Q1 through resistance R 1, the grounded emitter of triode Q1, the collector of a termination triode of capacitor C 1, the emitter of another termination triode of capacitor C 1, the base stage of one termination triode of resistance R 2, the other end ground connection of resistance R 2; Resistance R 1 is the feedback signal terminal of leaking with the node of capacitor C 1, the water leakage input end of this termination water purifier control module.
Described the first power supply is+24V that described second source is+5V.
Adopt the beneficial effect that technique scheme produces to be: on the line tower foundation of existing controller, increase leak detecting electrode and feedback circuit, the detecting electrode that leaks is two independently metal electrodes, be arranged on the water purifier inside junction that leaks.While leaking; water covers short circuit by two plate electrodes; short-circuit signal feeds back to the control module of water purifier through feedback circuit; enter the pattern of leaking: control module provides instruction and closes entering water electromagnetic valve, supercharge pump, scouring electromagnetic valve etc., in order to protect water purifier, and makes corresponding sound and light alarm; the prompting user machine that needs repairing; prompting user of service on-call maintenance, prevents that mishap from occurring, the serviceable life of having improved water purifier.
