Gas stove capable of realizing wide-range combustion

Abstract

The invention discloses a gas stove capable of realizing wide-range combustion. Each burner of the gas stove comprises an outer ring fire head part mixing cavity, a middle ring fire head part mixing cavity and an inner ring fire head part mixing cavity, wherein the inner ring fire head part mixing cavity is located in the middle ring fire head part mixing cavity. Outer fire covers of the gas stove circularly cover the upper portions of the outer ring fire head part mixing cavities. Inner ring fire holes are formed in the top faces of inner fire covers of the gas stove, middle ring fire holes are formed in the side walls of the inner fire covers, a cavity defined by the top face and the side wall of each inner fore cover is divided into two independent parts, one part of each cavity is an inner ring fire gas mixing cavity communicating with the corresponding inner ring fire holes, and the other part of each cavity is a middle ring fire gas mixing cavity communicating with the corresponding middle ring fire holes. The inner fire covers cover the upper portions of the middle ring fire head part mixing cavities, after covering, the inner ring fire gas mixing cavities of the inner fire covers communicate with the inner ring fire head part mixing cavities of the burners, and the middle ring fire gas mixing cavities of the inner fire covers communicate with the middle ring fire head head mixing cavities of the burners. By means of the stove, the lower limit value of firepower adjustment can be reduced, and stable combustion of flames in a low fire state can be ensured.

Description

technical field [0001] The invention belongs to the technical field of gas equipment, and in particular relates to a gas cooking stove, such as a gas stove, an integrated stove, and the like. Background technique [0002] A gas cooker is a kitchen appliance that uses gaseous fuels such as liquefied petroleum gas, artificial gas, and natural gas for direct fire heating. Existing gas cookers usually include components such as a cooker body, a burner, a pot support, an adjustment knob, an igniter, a valve body assembly, and an air intake pipe. Among them, the valve body assembly is installed on the stove body, and under the adjustment of the adjustment knob, the gas flow rate delivered to the burner is changed, and then the firepower of the burner is adjusted to adapt to different cooking conditions such as frying, frying, frying, steaming, stewing, and stewing. cooking scene. [0003] With the continuous development of gas cookers, the three-ring fire burner has been adopted...

AI Technical Summary

Problems solved by technology

When the firepower of the burner is adjusted to the maximum, flames are generated in all three fire covers, and the firepower can reach 5kW; when the firepower of the burner is adjusted to medium fire, only the middle ring fire cover and the inner ring fire cover have fire; When the firepower is adjusted to low fire, only the inner ring fire cover has fire, and the minimum firepower can only be as low as 0.8kW, there is a problem that the small fire is not small enough, and the flame is unstable in the low fire state
