Detailed ways

In conjunction with the accompanying drawings, describe in detail the specific implementation of the utility model:

As shown in Figure 1, the energy-saving device mainly includes a power socket 1, a closed casing 6, a transformer 7, a solenoid valve 9, and a traction magnet 8 are arranged in the casing 6, and a stove fan and a stove fan are arranged outside the casing. The air duct 5 connected to the air inlet pipe is provided with a wind deflector 3 and a manual wind deflector 4 in the air duct, the wind deflector 3 is linked with the ejector rod 13 on the traction magnet 8, and the solenoid valve 9 is fixed in the casing 6 On the bottom plate, the inlet and outlet oil and gas pipes 10 used as oil and gas passages are located outside the housing 6, and a normally open pipe 15 is arranged between the inlet and outlet pipe ports, and a normally open oil and gas regulating valve 11 is arranged on the normally open pipe 15. A tuyere 12 is also arranged at the bottom of the air duct, and the tuyere 12 communicates with the inside of the casing. The control switch 2 of solenoid valve 9 and traction magnet 8 is an inductive infrared switch, which is fixed on the baffle plate behind the cooking range. One end of the induction switch 2 is connected to the transformer 7 (which can be replaced by a storage battery), and the output end is connected to the solenoid valve 9 and the traction magnet 8. Located at the outlet of the cooling air duct 14, the cooling air duct 14 communicates with the inside of the housing 6, and the air blown by the fan enters the housing 6 through the tuyere 12 to reduce the temperature in the housing and control the temperature of the switch 2.

As the structural diagram shown in accompanying drawing 2, its control switch can be mechanical, and is made of fire-off pressing bar 16, pull bar 18 and sleeve pipe 17, and fire-off pressing bar 16 is fixed on the fire ring on furnace body top, and is positioned at The pull rod 18 in the casing 17 is interlocked, and a return spring 19 is sleeved on the pull rod 18. A contact electrode 20 is arranged at the bottom of the pull rod 18, which is connected with the transformer 7 or the positive pole of the battery. A contact electrode 20 is also arranged in the casing 17. The corresponding contact electrode 21 is connected to the electric traction magnet 8 and the solenoid valve 9 .

During use, one end of the air duct 5 is connected to the blower fan, and the other end is connected to the air inlet pipe of the stove, and one end of the oil and gas pipe outside the electromagnetic valve 9 is connected to the inlet of oil or gas, and the other end is connected to the conduit of the stove oil or gas. For embodiment 1, the induction switch 2 is arranged on the baffle plate behind the cooking range. When the pot is put for cooking, the induction switch 2 is turned on, and the solenoid valve 9 and the traction magnet 8 are energized. The road supply oil gas is supplied into the combustion chamber in the furnace through the connecting pipe to start the high-power oil supply work. Simultaneously, the ejector rod 13 on the traction magnet 8 ascends and opens the windshield 3, so that the fan gale enters into the cooking range by the air pipe 5 and starts high-power air supply work. Use the manual windshield 4 to adjust the air intake. When the wok is off the fire, the induction switch is disconnected, the solenoid valve 9 and the traction magnet 8 are powered off, the solenoid valve 9 and the valve 11 close the oil circuit, and the ejector rod 13 on the traction magnet 8 is reset. , so that the air duct is closed. And when the combustion chamber in the kitchen range, only keep a little oil and air pipe at the bottom of the solenoid valve 9 and a little oil or gas input into the combustion chamber to keep the kindling, so as to realize that the fire is fierce when used, and the pot is not used when it is not used. Energy-saving measures to cut off the fire.

For Example 2, when igniting the fire and putting the pot for cooking, use the self weight of the pot to press down the fire-off pressure bar 16 fixed on the fire ring and shrink the return spring 19 through the pull bar 18 so that the contact piece in the sleeve at the lower end of the pull bar 18 contacts the electromagnetic Iron 8, electromagnetic valve 9 are energized, open valve after electromagnetic valve 9 is energized, and oil is fed into the combustion chamber in the furnace from the large oil circuit of oil pipe 10 or gas circuit by connecting conduit and starts high-power oil supply work. After the traction magnet 8 is energized, it goes up and opens the windshield 3. The strong wind of the fan enters the combustion chamber of the stove through the air pipe 5 and starts the high-power air supply work. Above these working strokes all are to form the work at the instant that fire-off pressure rod 16 is subjected to frying pan gravity, inching, do not influence the required firepower of cooking, and firepower size is the same as current market oil, gas dual-purpose cooker by adjusting oil supply or gas master. Needed firepower when valve and manual windshield 4 realize cooking. When the frying pan in the cooking needs to be removed from the fire to add seasoning or when the finished dishes are put out of the pan, or when the cooking is suspended for a short time, due to the leaving of the frying pan, the fire-off pressure bar 16 is no longer stressed, and the return spring resets at this time, pushing The pull rod is downward, the lower end of the pull rod is disconnected from the contact electrodes 20, 21 on the bushing, the solenoid valve 9 and the traction magnet 8 are powered off and stop working, and the wind, oil, and gas are cut off at the same time; A little bit of oil or gas input into the combustion chamber by the solenoid valve 7 bottom usually leads to oil or air pipe 15 to keep the fire. The cooling air duct 14 communicates with the sleeve pipe 17, and the cooling measures of the fire-off pressure rod 16, the pull rod 18 and the return spring 19 are that a small gust of wind enters the housing 6 through the fan 12, and blows cold air through the cooling air duct 14 to enter the cooling system. .
