Description

Technical Field

[0001] The present invention relates to the technical field of burners, and in particular to a double-valve body high-power burner. Background Art

[0002] The national standard power of household burners is that the power of a single control valve controlling the ring fire cannot exceed 5.28KW. Burners under this power can usually only meet normal household cooking needs, but for the needs of stir-frying some dishes, the power obviously cannot meet the needs. Although the three-ring fire burners on the market can achieve three fire rings burning at the same time, these three-ring fire burners on the market all use the same control valve to control the flame, which results in the three-ring fire burners under full power cannot exceed 5.28KW, so the demand for stir-frying cannot be met.

[0003] As a result, a burner with a control valve for stir-frying has gradually appeared on the market, such as a three-ring gas stove with stir-frying function disclosed in Chinese patent document CN219674305U, including a burner, the burner having an outer ring ejector pipe, a middle ring ejector pipe and an inner ring ejector pipe, which also includes a stir-frying structure connected to the middle ring ejector pipe, the stir-frying structure at least includes a stir-frying valve assembly, the stir-frying valve assembly includes: a valve body, having a stir-frying gas path and a middle ring gas path, the stir-frying gas path is connected to the air inlet end of the middle ring ejector pipe through the middle ring nozzle or the stir-frying air duct of the stir-frying nozzle assembly, and the middle ring gas path is connected to the air inlet end of the middle ring ejector pipe through the middle ring nozzle or the conventional air duct of the stir-frying nozzle assembly.

[0004] That is to say, in the existing three-ring gas stove structure with stir-fry function, gas is mainly supplied to the middle ring gas circuit through the valve body, so that the power of the middle ring gas circuit is superimposed, thereby increasing the power of the burner to achieve the stir-fry function. However, in this structure, in actual daily use, since stir-fry is not used frequently, and the maximum power of a commonly used single valve body cannot exceed 5.28KW, it is not possible to switch to different numbers of fire rings for cooking at the maximum power of this single valve body, and the function is relatively simple. Summary of the invention

[0005] In order to overcome the defects of the prior art, the present invention provides a double-valve body high-power burner to solve the problems in the prior art.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a double-valve body high-power burner, including a burner body, on which an outer fire ring, an inner fire ring and a central fire ring are arranged, the double-valve body high-power burner also includes a first solenoid valve and a second solenoid valve, the first solenoid valve is connected to a first air pipe and a second air pipe, the first air pipe is connected to the ejection pipe of the outer fire ring, the second air pipe is connected to the ejection pipe of the central fire ring, the second solenoid valve is connected to a third air pipe and a fourth air pipe, the third air pipe is connected to the ejection pipe of the inner fire ring, the fourth air pipe is connected to the ejection pipe of the central fire ring, the first solenoid valve and the second solenoid valve are both connected to a flameout protection needle, the flameout protection needle is located on one side of the central fire ring, so that the central fire ring can burn simultaneously with the outer fire ring or the inner fire ring.

[0007] The beneficial effects of the present invention are that the first solenoid valve is used to control the combustion of the outer fire ring and the central fire ring, and the second solenoid valve can control the combustion of the inner fire ring and the central fire ring. Since the first solenoid valve and the second solenoid valve can be controlled separately, each solenoid valve can achieve the maximum power that can be controlled, and the control of different solenoid valves can achieve different flame positions. Different fire ring positions can be switched under the same power, which is more suitable for cooking with a variety of pots. Moreover, the first solenoid valve and the second solenoid valve can simultaneously superimpose the outer fire ring, the inner fire ring and the central fire ring to form high power to achieve the stir-fry function, which is more flexible to use. During use, the central fire ring is in a "constantly on" state, and the flameout protection needle can conveniently detect the flame to prevent the flameout protection switch from being accidentally started.

[0008] Furthermore, the first solenoid valve is connected to the flameout protection needle through a first signal line, and the second solenoid valve is connected to the flameout protection needle through a second signal line.

Under the action of the thermal insulation component, the telescopic temperature sensor can be prevented from being directly burned, thereby increasing the service life of the telescopic temperature sensor and improving the accuracy of detection.

[0014] Furthermore, the thermal insulation component includes an insulation ring, which is installed at the upper end of the central fire ring. The insulation ring is consistent with the central axis of the third air replenishment hole, so that an air replenishment channel is formed between the insulation rings, and the telescopic temperature sensor is installed in the air replenishment channel.

[0015] After adopting the above-mentioned further structure, during the combustion process of the central fire ring, the air supplement channel can allow air to flow from bottom to top, so that the cold air directly contacts the telescopic temperature sensor and takes away the heat from the telescopic temperature sensor.
