A center hole is formed in the vortex supercharging firearm, a secondary combustion-supporting tube is fixed in the center hole, the energy-saving burner is arranged in the energy-saving Chinese meal frying oven, an air outlet of a waterproof fan in the Chinese meal frying oven is connected to the air intake pipe on an oven core, a flame-out protection type electronic ignition infrared economizer is further provided, and a device, which is capable of automatically feeding and replenishing water and stopping after the water is full, is arranged on a hearth of the frying oven. The energy-saving Chinese meal frying oven and the energy-saving burner have good energy-saving effect.

Description

technical field [0001] The invention relates to a gas stove, in particular to an energy-saving frying stove and a burner. Background technique [0002] As a heating device for cooking, gas stoves have been widely used by people all over the world. Existing gas cookers have the disadvantages that the depth of the stove chamber and the stove core is too large, the contact area between the flame and the frying pan is small during combustion, and the heating is uneven, the heat energy transfer is limited, and the structure is unreasonable. The proportion of air intake and gas intake is uneven and the excess air intake makes 20% of the gas not burned in time and is blown away by a large amount of air, causing the flame to turn red and yellow when it burns, resulting in insufficient combustion, and the combustion of the gas. The thermal efficiency can only reach about 20%, so that the exhaust gas such as carbon monoxide and nitrogen oxides is discharged from the chimney together ...

AI Technical Summary

Problems solved by technology

Existing gas cookers have the disadvantages that the depth of the hearth and the core is too large, the contact area between the flame and the frying pan is small, the heating is uneven, the heat transfer is limited, and the structure is unreasonable.

The ratio of air intake to gas intake is uneven and the air intake is excessive, so that 20% of the gas will not be burned in time and will be blown away by a large amount of air, resulting in insufficient combustion and reddish yellow when the flame burns. The thermal efficiency can only reach about 20%, so that exhaust gases such as carbon monoxide and nitrogen oxides are discharged from the chimney together with incompletely burned gas, resulting in a serious emission exceeding the standard and a great waste of fuel; Only about 800 degrees; a large amount of heat is lost during combustion, which increases the temperature of the kitchen

[0003] The existing gas cooker is composed of a stove, a pot ring fixed on the top of the stove, and a stove core fixed on the bottom of the stove. The pot ring is made of cast iron, so the pot ring is easy to burn, the stove life is short, and the stove core Very easy to damage, which greatly affects the service life of the gas cooker

The height of the fire distributor of the stove core in the existing gas cooker is only about 5cm, and there is a circular air inlet hole on the fire distributor. Due to the limitation of the height of the fire distributor, in order to allow the gas to pass through, there are fewer circular air inlet holes and large apertures. In this way, when the airflow passes through the circular air intake hole, the speed is fast and the impact force is large, resulting in high noise

At the same time, the faucet installed on the gas stove is manual, which is inconvenient to operate, and the faucet is usually in a normally open state during work, which greatly wastes water resources; the gas stove has no protection device for abnormal flameout and gas leakage, and the gas stove and the operator are both Security risks

Moreover, traditional gas stoves can only ignite the fuel by manual ignition or by leaving a constant open flame. When burning, the gas entering the gas pipeline is not restricted, and exhaust gases such as carbon monoxide and nitrogen oxides and incompletely burned gas will be released together. The discharge of the chimney makes the emission of carbon monoxide and nitrogen oxides seriously exceed the standard, which greatly pollutes the environment and wastes fuel
