Abstract
The utility model relates to an electric rice cooker, in particular to an electric rice cooker control circuit capable of automatically powering down. The electric rice cooker control circuit comprises a power panel, a controller and a control switch which is arranged on a power supply input line. The electric rice cooker control circuit is characterized by further comprising a relay, a control end of the relay is connected with the controller, and a normally open contact of the relay and the control switch are arranged on the power supply input line in parallel. According to the electric rice cooker control circuit capable of automatically powering down, the relay is added on the basis of an existing electric rice cooker control circuit, the electric rice cooker controls the relay to be powered down through the controller after the electric rice cooker completes work, and automatic powering down of the electric rice cooker is achieved.
Description
Technical field
The utility model relates to a kind of electric cooker, is specially a kind of electric cooker control circuit of outage voluntarily.
Background technology
At present, the electric cooker of commonly using itself does not have breaker device, electric cooker is in holding state always after powering on He after finishing using, the user only have with power-line plug pull out could realize the outage, concerning without the user who pulls out the electricity custom, the electric cooker of commonly using can cause unnecessary stand-by power consumption, and is in for a long time "on" position, also can bring uncertain potential safety hazard and electrical loss.
The utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of the electric cooker control circuit of outage voluntarily.
Described a kind of electric cooker control circuit of outage voluntarily, comprise power panel, controller and gauge tap, gauge tap is arranged on the power input line road, it is characterized in that: this control circuit also comprises a relay, the Control end is connected with controller, and the normally opened contact of relay and gauge tap are arranged in parallel on the power input line road.
Described a kind of electric cooker control circuit of outage voluntarily is characterized in that being arranged in parallel with relay normally open contact after described gauge tap serial connection one current-limiting resistance.
Described a kind of electric cooker control circuit of outage voluntarily is characterized in that described power panel is controller and relay power supply.
The utility model has increased relay on existing electric cooker control circuit basis, electric cooker disconnects by the controller control relay after work is completed, and realizes electric cooker oneself outage.
Description of drawings
Fig. 1 is electrical block diagram of the present utility model;
In figure: 1-gauge tap, 2-power panel, 3-load, 4-relay, 5-controller.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of electric cooker control circuit of outage voluntarily, comprise power panel 2, controller 5 and gauge tap 1, gauge tap 1 is arranged on the power input line road, this control circuit also comprises a relay 4, power panel 2 is controller 5 and relay 4 power supplies, relay 4 control ends are connected with controller 5, and the normally opened contact K1 of relay 4 and gauge tap 1 are arranged in parallel on the power input line road; In order to ensure the reliability of electric cooker work, can will be arranged in parallel with relay 5 normally opened contact K1 after gauge tap 1 serial connection one current-limiting resistance R1, the resistance R 2 in Fig. 1, resistance R 3, triode Q and diode D1 consist of relay protection circuit.
The course of work: after being plugged power line, pressing gauge tap 1 and power to power panel 2 temporarily, power panel 2 offers controller 5 and relay 4 operating voltages, controller 5 control relay 4 adhesives immediately; Unclamp gauge tap 1, gauge tap disconnects, and continued to circuit normal power supply by the relay 4 after adhesive this moment; After electric cooker work is completed, at the appointed time disconnected by the programme-control relay of controller according to inside, circuit and civil power disconnect, and electric cooker quits work.
Claims (3)
- One kind voluntarily the outage electric cooker control circuit, comprise power panel, controller and gauge tap, gauge tap is arranged on the power input line road, it is characterized in that: this control circuit also comprises a relay, the Control end is connected with controller, and the normally opened contact of relay and gauge tap are arranged in parallel on the power input line road.
- 2. a kind of electric cooker control circuit of outage voluntarily according to claim 1, is characterized in that being arranged in parallel with relay normally open contact after described gauge tap serial connection one current-limiting resistance.
