Abstract

The utility model relates to a multipurpose power cut controller, which comprises a relay interlock switch, a system power supply circuit, an adjustable current-limiting control circuit, an overvoltage protective circuit, a timing circuit, a water control circuit, a water boiled water control circuit, an auxiliary gas kitchen, a gas water heater power supply circuit, a charging circuit, an indicator lamp, etc. The multipurpose power cut controller controls power cut through detecting water vapor generated when water is boiled, or automatically shuts off the circuit and cuts off the output and power supply when water is full or a set timing time is reached or the commercial power exceeds voltage; meanwhile, the gas kitchen, the gas water heater power supply and the charging power supply are subsequently cut off. The multipurpose power cut controller has the advantages of no or less use of battery, environmental friendliness, multiple functions, low energy consumption, simple circuit, good economic performance and practicality, good safety and reliability, and easy generalization.

Description

Use circuit breaking controller more

Technical field:

The utility model relates to a kind of power down switch of timing time delayed turn-off, the multi-purpose controller of water boiling water control outage.

Background technology:

Use the electric heating appliance boiling water, often forget and turn-off thousands of boiling water, even have temperature controller in the electric water boiler, also be that temperature-sensitive is simulated, the contact often burns out, and the performance of using temperature controller of a specified duration all can change, and is to boil water less than the just outage of 100 degree, perhaps water has been opened and has not also been controlled outage for a long time, even burns out danger such as electrical equipment; Draw water with water pump, often forget and turn-off and the waste water power, burn out electrical equipment etc., the pumping controller that has, ionizing and electrolyzing water destroys water quality, and water level controller is often out of control, during actual the use, the water surface of water tank, water tower springs up up and down, the contact point switch-on and-off, and the frequent adhesive of contactor discharges, burn out contactor, burn out motor; Irregular startup, the late into the night, noise was disturbed the people, multiple factor, the user have to be installed electric brake additional, becomes semi-automatic, and it is unnecessary that controller has become; Owing to reasons such as the stall load heighten, lacked current control during machine operation, motor is burnt out, caused damage; Controller circuitry complexity such as great majority draw water, function singleness, the cost height, safeguard difficult, be not easy to promote.

Summary of the invention:

The utility model purpose: at the present situation of existing above-mentioned controller deficiency, a kind of circuit breaking controller of using is provided more, design is regularly drawn water as required, water completely turn-offs, electric heating appliance such as thermos bottle, insulating pot is to boil water, detects the electric conductivity of the water in the water vapour of water boiling back and controls outage, guarantees that poach opens, taps outage source, sensitive reliable; Also can do the power supply control of kitchen waste treater; Simultaneously the also additional 3V power supply of this controller is made the gas kitchen power supply, and the gas heater power supply is without battery, use battery, environmental less; The 3V power supply, the 5V charging circuit also is subjected to turn-off control; And current control, overpressure protection arranged; Function is neat, and is convenient, and safety is energy-conservation, environmental protection.

The utility model is achieved through the following technical solutions, and a kind ofly uses circuit breaking controller more, comprises shell, the tape relay interlock switch; the power circuit of 12V and 3V, the 5V charging circuit, timing circuit, the water boiling water is full, the water control circuit; cross current control, overpressure protection circuit, compositions such as pilot lamp.System power supply is the power supply of transformer transformation rectifying and wave-filtering, and one the tunnel connects the overpressure protection circuit, water control circuit, timing circuit, the overcurrent control circuit of rationing the power supply, and charge power supply is made through voltage stabilizing in another road; After taking out dog days' tap rectifying and wave-filtering, transformer secondary output makes the power supply of gas kitchen, gas heater in addition; The overpressure protection control signal that constitutes by stabilivolt and Resistor-Capacitor Unit; by triode; resistance; water boiling water control probe constitutes the completely control signal of two sensitivity of height of water boiling water; by timer; resistance; diode or constitute timing signal through the circuit of setting time with time-base integrated circuit and resistance capacitance; mutual inductor is serially connected in master control electrical equipment input end; the current/voltage of secondary induction is through rectifying and wave-filtering; mistake flow control signals through the Resistor-Capacitor Unit buffering; these signals all insert triode in the lump and amplify; the signal of its conducting is delivered to the execution relay coil; the tape relay interlock switch is serially connected with the power supply input/output terminal, control entire circuit break-make.

Regularly: drive timer earlier, mix up the schedule time, if timer pull out often open the position cancel timing function.Be pressed into interlock switch, power on circuitry, the power supply water supply control circuit of transformer transformation rectifying and wave-filtering and superpressure detect and timing circuit work.Resistance R 7 connects power supply negative terminal through timer, and timing arrives, and timer disconnects, and power supply is through resistance R 7, and diode D4, to the Q1 base stage rises the Q1 base potential, the Q1 conducting, and relay coil gets electric adhesive, cuts off the electricity supply.

Overpressure protection: transformer-secondary voltage changes with civil power, and when stabilivolt VD1 detected voltage above setting value, stabilivolt VD1 conducting was risen the Q1 base potential, the Q1 conducting, and relay coil gets electric adhesive, cuts off the electricity supply.

Water control: relay coil one termination power in the interlock switch, one termination control triode Q1, Q1, Q2 form complex pipe, constitute high sensitivity water control circuit with R5, R6, R8, as long as biasing resistor R6 forms path through water resistance to power supply negative terminal, the Q2 conducting, the Q1 conducting, the adhesive of interlock switch relay power, the self-lock switch self-unloading discharges, power remove.Power supply is formed muting sensitivity water control circuit through the resistance of water and R8, Q1, can be used for detecting the electric conductivity that water boiling back water vapour is condensed into water and controls outage, also can insert the temperature control breaker device.

Cross current control: be serially connected in the transformer induced voltage of input end, through rectifying and wave-filtering adjustable resistance W1 dividing potential drop, control the Q1 conducting, relay coil gets electric adhesive, and the self-lock switch self-unloading discharges, and power remove plays adjustable electricity-limiter effect.
