Working principle of energy saving:

Put the pot into the heat-capacity gas stove, a relatively sealed space is formed in the stove, and there is a certain gap between the top of the partial-pressure heat-capacity flame deflector and the bottom of the pot.

Turn on the power switch. DCV4, 18650 Complementary DC power supply powers the control system of the gas stove. DC digital voltmeter displays real-time DC voltage.

Start the ignition switch, the control system of the gas stove works, the solenoid valve opens, the gas passes through the gas pressure reducing valve, the gas filter, the solenoid valve assembly, the gas pipe reaches the gas jet pipe assembly, and the nozzle presses 2.80kpa to the stove fire. The air intake hole at the bottom of the fire row is ejected, the injected gas is mixed with the gas in the hole, and the gas mixture moves from the bottom of the fire row to the top of the fire row. When the gas mixture reaches the top of the fire row, the mixture meets the spark from the ignition needle. When burning, the flame accurately heats the bottom of the pot from the heat-insulating fire-guiding ring at the bottom of the gas stove through the partial pressure heat-capacity flame deflector above the heat-insulating fire-guiding ring.

Because the mixture is burned in the stove, the temperature inside the stove is several times higher than the temperature outside the stove, and a low-pressure area is formed in the stove, so the low-pressure hot air in the stove and the high-pressure cold air outside the stove produce cold and heat convection.

The cold air under the gas stove enters the stove from the gap of the fire row of the stove to assist the combustion.

Another high-pressure cold air enters the stove from the exhaust port of the pot base. The exhaust gas exhaust port on the pot base is larger than the fire exhaust gap of the stove fire, so the cold air entering the stove from the exhaust gas exhaust port is larger than that from the stove fire exhaust port. There is a lot of cold air entering the stove in the gap, and the downward pressure is large. Due to the combustion of gas, the heat energy generated when the gas burns makes the partial pressure heat capacity flame guide hot, and the partial pressure heat capacity flame guide becomes the windbreak wall of the hottest area in the stove.

Therefore, the cold air entering the stove from the exhaust gas exhaust port goes straight to the partial pressure heat capacity flame guide. Since there are no holes in the lower part of the partial pressure heat capacity flame guide, the cold air flows along the partial pressure heat capacity. When the cold air reaches the air inlet on the upper part of the partial pressure heat capacity flame guide, the cold air flows into the partial pressure heat from the air inlet on the upper part of the partial pressure heat capacity flame guide. In the container flame deflector, the crescent-shaped annular inner cavity is sprayed upward from the bottom outlet hole of the partial pressure heat capacity flame deflector, so that the downward pressure of the cold air becomes the upward combustion-supporting thrust of the flame. Therefore, the cold air that is prevented from flowing into the stove from the exhaust gas exhaust port presses the flame to the bottom of the stove, and improves the thermal efficiency of the pot.

The heat energy generated by the combustion of gas cannot be completely absorbed by the cooker, and part of the heat energy that cannot be absorbed by the cooker is absorbed by the flame deflector, and the other part is stored by the heat capacity layer of the gas stove.

When the pot reaches the cooking temperature, adjust the heat adjustment knob to a smaller position. At this time, the flame deflector and the heat capacity layer in the stove release heat to the pot, so that the pot is always kept at the cooking temperature, thereby achieving the effect of energy saving.

The gap between the arc at the top of the flame deflector and the bottom of the pot is the starting point for the exhaust gas generated when the gas burns.

When the gas stove control system is turned off, or the gas stove is unexpectedly extinguished, the flame detection circuit in the control system will quickly feed back the information of the gas stove's fire to the control system. Gas safety.
