Abstract

The utility model provides an energy economizer for gas-fired kitchen range, which comprises an infrared signal emitter and an infrared signal receiver installed in both ends of the stove and a magnetic valve installed in the inlet pipeline. Wherein, the infrared signal emitter, the infrared signal receiver and the magnetic valve are connected with the controller which connects with the power source. When the utility model is communicated with the power source, the light sent by the emitter is received by the receiver; the pot positioned in the middle cuts the light; the controller controls the magnetic valve for connection; fire appears in the stove. When the pot leaves the stove, the receiver receives the light; the controller cuts the loop of the magnetic valve; the magnetic valve stops; the gas is cut and the branched valve gate is opened; large fire is extinguished and fire appears, so as to save energies.

Description

Combustion gas kitchen tools energy-saving appliance

Technical field

The utility model relates to a kind of energy-saving appliance, particularly a kind of energy-saving appliance that is installed on the combustion gas kitchen tools.

Background technology

Now local major parts of other specialty cookings are all used gas-cooker in the hotel etc., because the cook will often add water, refuel or add material in the process of cooking, often pot to be removed from gas-cooker, so the gas-cooker that they use is kind of a fire gas combustion range mostly, planting fire gas combustion range is to open air valve in use, normal combustion, the cook with pot when kitchen range is removed, can air valve be closed by knob and only stay kind of a fire, directly air valve is opened in the time of will using once more, again ventilate, ignite by kind of a fire and both can use.But because the number of times of cook's mobile frying pan in gastronomical process is very frequent, in order to save combustion gas, need pick up frying pan at every turn and just close gas check valve, such operation is loaded down with trivial details especially, so a lot of cooks can not remove to close gas check valve when picking up frying pan in the cooking process, and this type of cooking stove firepower is big usually, gas output is big, so the combustion gas wastage when empty kitchen range is big especially, has caused unnecessary loss.

Summary of the invention

The purpose of this utility model provides a kind of combustion gas kitchen tools energy-saving appliance that can effectively overcome the problems referred to above generation, and it can close gas check valve when empty kitchen range, saves the use of combustion gas, reduces consuming energy savings.

The purpose of the utility model structure is achieved in that it includes the signal projector and the signal receiver that are installed in the cooking stove two ends, is installed in the magnetic valve on the admission line, signal projector, signal receiver and magnetic valve link to each other with controller, and controller connects power supply;

In the said structure, signal projector and signal receiver are infrared projector and infrared signal receiver;

In the said structure, controller is made up of reduction voltage circuit, current rectifying and wave filtering circuit, infrared induction automatic control circuit and solenoid valve control circuit.

In sum, the light beam that combustion gas kitchen tools energy-saving appliance energising of the present utility model back transmitter sends is received by the receiver, and the centre is a frying pan, and frying pan cuts off light beam, and big fire appears in controller control magnetic valve connection work in the kitchen range; Frying pan is behind kitchen range, and receiver receives light beam, and controller cuts off the loop of magnetic valve, and magnetic valve quits work, and closes gas, and branch gas valve is opened, and big fire is extinguished and kindling material occurred, reaches energy-saving effect.

Description of drawings

Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail

Fig. 1 is the utility model combustion gas kitchen tools energy-saving appliance structure chart

Fig. 2 is the circuit diagram of the utility model combustion gas kitchen tools energy-saving appliance controller

The specific embodiment

As shown in Figure 1, it includes combustion gas kitchen tools energy-saving appliance in the present embodiment infrared signal 310 transmitters and the infrared signal receiver 320 that are installed in cooking stove 500 two ends, is installed in the magnetic valve 200 on the admission line 400, and infrared projector 310, infrared signal receiver 320 and magnetic valve 200 link to each other with controller 100.

As shown in Figure 2, in controller circuitry, single-phase 220V civil power after fuse F1 (1A) protection, is 12V by transformer T1 step-down through AC1, the input of AC2 two ends.Through the 12V alternating voltage that transformer T1 descends, be input to 2 pin, 3 pin of rectifier bridge heap U3, the DC voltage after the rectification, 1 pin are for just, and 4 pin are for negative, and inductance L 1 and electrochemical capacitor EC1 composition filter circuit make the DC voltage of output more level and smooth.

Among the figure+,-be respectively positive source, the negative pole of infrared switch, 0 is output, by the current rectifying and wave filtering circuit output voltage, one the road supplies with the infrared induction power supply, another road is supplied with relay U1, U2 coil respectively, the common point of two relays is connected to the output of infrared switch, and for enough electric currents are provided to infrared switch, circuit meets the demands with two relay parallel connections.D6, C1 form holding circuit, make relay U1, U2 at switch moment generation high pressure, absorb ground connection through D6, C1.

Magnetic valve is through 2 places in circuit of P, NB2, and diode D1, D2, D3, D4 form bridge rectifier, and magnetic valve work and dc source are provided, and the high pressure that produces during electromagnetic valve switch is protected the unlikely damage of other element through sustained diode 5 short circuits.The normally opened contact of relay U1 and U2 is controlled connection, the disconnection in magnetic valve loop, reaches the purpose of automatic control.

The combustion gas kitchen tools energy-saving appliance of present embodiment, the light beam that energising back transmitter sends is received by the receiver, the centre is a frying pan, frying pan cuts off light beam, the infrared switch output is a low-voltage, and relay U1, U2 are in running order at this moment, and two relay normally open contact 1 pin, 3 pin are connected, work is connected in magnetic valve (P point, NB2) loop, occurs big fire in the kitchen range; Frying pan is behind kitchen range, receiver receives light beam, the infrared switch output is a high voltage, two relay two ends were in high potential simultaneously and quit work this moment, also just cut off the loop of magnetic valve, and magnetic valve quits work, close gas, branch gas valve is opened, and big fire is extinguished and kindling material occurred, reaches energy-saving effect.
