Description

Combustion gas automatic safety energy-saving cooking

Technical field

The utility model relates to a kind of cooker, particularly a kind of gas stove.

Background technology

In the prior art, a kind of self-control safety energy-saving cooking is arranged, comprise the stove heart that is installed on the range panel, stove mouth in the heart is provided with and can presses bar by what pot pressed, the intracardiac bottom of stove connects inlet ductwork, inlet ductwork is connected source of the gas through magnetic valve and manual main valve, the magnetic valve import and export is arranged in parallel the kindling material control valve of low discharge, pressing the bar other end links with the touch-pressure switch that is fixed under the range panel, the coil of touch-pressure switch and magnetic valve is connected in series in both ends of power, for making stove heart sufficient combustion, stove also is connected with the blast pipe that links to each other with the blower fan outlet in the heart.During this device busy, by pot shelve and put down the break-make that can control touch-pressure switch, realize the opening and closing of magnetic valve, for device can normally be used when cutting off the power supply, magnetic valve adopts the magnetic valve of outage unlatching, and touch-pressure switch employing is simultaneously depressed disconnection, lifted the switch of connection, during use, the kindling material control valve is held open state, lights kindling material earlier, when pot is put cooking stove, pot is depressed and is pressed bar, and touch-pressure switch disconnects, the magnetic valve outage, spool is opened, and the kitchen range heart transfers big fire burns to; When pot left cooking stove, touch-pressure switch got electric, made magnetic valve connect power supply, closed electromagnetic valve, the kindling material control valve is held open state, and the kitchen range heart only keeps very little kindling material burning, plays energy-conserving action, when pot was put cooking stove once more, control valve was opened, and kindling material transfers big fire burns to; This device need not the manual main valve of hand switch, promptly can make the conversion automatically between big fire burns and kindling material burning of the stove heart with the placement and the disengaging of pot; Its weak point is: the kindling material burning still needs combustion oil or gas, and energy waste is still arranged; In addition, kindling material is gone out by wind easily, influences the dependability of device.

The utility model content

The purpose of this utility model provides a kind of combustion gas automatic safety energy-saving cooking, make its can be with the placement of pot auto-ignition combustion, with pot pick up and auto extinguishing can be avoided the fryer danger of repeatedly lighting a fire, reach the energy-saving safe effect.

The purpose of this utility model is achieved in that combustion gas automatic safety energy-saving cooking, comprise the stove heart that is installed on the range panel, stove mouth in the heart is provided with and can presses bar by what pot pressed, the intracardiac bottom of stove connects inlet ductwork, inlet ductwork is through getting electric electromagnetic valve closed and manual main valve connection source of the gas, pressing the bar other end links with the touch-pressure switch of depressing disconnection that is fixed under the range panel, touch-pressure switch and magnetic valve insert correspondent control circuits, described control circuit comprises power supply, power supply is given main relay and the very first time relay power supply that is in parallel through power switch and touch-pressure switch, and the coil of magnetic valve is delayed time to close with often opening of very first time relay and is connected across very first time relay two ends after contact is connected; Both ends of power is inserted in first normally closed interlock of power switch, main relay and second time relay back that links to each other in proper order, is connected across second time relay two ends after the contact series connection is opened in the normally closed time-delay that is arranged on the intracardiac ignition transformer of stove and second time relay.

The utility model when work, the power-on switch, when pot is not placed on stove in the heart the time, touch-pressure switch is connected, and main relay and very first time relay get electric, and the normally closed interlock of main relay disconnects, and ignition transformer is not worked; The time-delay of often opening of very first time relay is closed contact and is got electric back time-delay closing, and it is electric that electromagnetic valve coil is got, closed electromagnetic valve; When cooking, open manual main valve, simultaneously pot being placed on stove makes it depress to press bar in the heart, press bar and drive the touch-pressure switch disconnection, make main relay and very first time relay electric-loss, the contact disconnection is closed in the time-delay of often opening of very first time relay, the electromagnetic valve coil dead electricity, magnetic valve is opened, to stove heart air feed, simultaneously, the normally closed interlock closure of main relay, second time relay gets electric, and its normally closed time-delay is opened the contact and is got in the electric back delay time that disconnects of delaying time, ignition transformer work, the combustion gas that stove is intracardiac is lighted, and after time-delay, the normally closed time-delay of second time relay is opened the contact and disconnected, stop igniting, at this moment, the cook can carry out cooking, in the cooking process, may can the short time leave the stove heart by pot, it is electric that very first time relay is got and since very first time relay often open the effect that contact is closed in time-delay, the coil of magnetic valve can not be rapid, make magnetic valve can be held open state, the stove heart is unlikely flame-out, and main relay gets electric, and its first normally closed interlock disconnects, ignition transformer opens circuit, when pot is depressed when pressing bar once more, the rapid dead electricity of very first time relay, it is often opened time-delay and closes contact and keep off-state, magnetic valve is held open, the sustained combustion of stove internal heat flame; When dish need take the dish out of the pot, pot leaves the stove heart, touch-pressure switch is connected, very first time relay and main relay get electric, and contact timing closing, magnetic valve time-delay closing are closed in the time-delay of often opening of very first time relay, stove heart gas supply cuts off flame-out, first normally closed interlock of main relay disconnects, so ignition transformer keeps opening circuit, gets ready in the heart for next pot is placed on stove once more; If loss of ignition, be placed into kitchen range more in the heart after pot can being picked up, light a fire once more, can avoid repeatedly lighting a fire fryer danger takes place, the utility model can be with the placement of pot auto-ignition combustion, can with pot pick up and the auto extinguishing of delaying time has been avoided the trouble of frequent manual ignition, reduced the energy waste that divides the dish gap; Can avoid the fryer danger of repeatedly lighting a fire, reach the energy-saving safe effect.

For making the intracardiac fuel gas buring of stove more abundant, second normally closed interlock of described main relay and the limit and corresponding power supply one end that are connected power switch after an air blast links to each other in proper order, the normally open contact of main relay and the second normally closed interlock two ends that are connected across main relay after load governor is connected, stove also are connected with the blast pipe that links to each other with the blower fan outlet in the heart.When pot is placed on stove in the heart the time, blower fan is connected power supply through second normally closed interlock of the main solenoid valve of closure, and the blower fan strong wind provides enough combustion airs for the big flow combustion gas that comes from magnetic valve, can increase firepower; When pot leaves the stove heart, second normally-closed contact of main relay disconnects, the normally opened contact closure of main relay simultaneously, and blower fan is connected power supply through load governor, can make blower fan transfer low cruise to, the energy loss of having avoided furnace temperature to reduce fast.
