Gas stove

Abstract

The invention relates to the technical field of gas stoves, and provides a gas stove. The gas stove comprises a stove body, a bracket erected on the stove body, burner assemblies arranged in the stove body and a control circuit arranged in the stove body, wherein each burner assembly comprises a burner, a gas inlet pipe connected to the burner, a valve, a gas pressure sensor and a lifting device mounted at the bottom of the burner, the valve and the gas pressure sensor are arranged sequentially on the gas inlet pipe in the gas inlet direction, and the valve, the gas pressure sensor and the lifting device are electrically connected with the control circuit respectively. According to the gas stove, the opening degrees of the valves are different, then the flame heights of the burners are different, the gas pressure values detected by the gas pressure sensors are also different, therefore, a corresponding relation between the gas pressure and the flame height can be established; the control circuit can control lifting and dropping of the lifting devices according to the gas pressure detected by the gas pressure sensors, then the burners are driven to lift and drop, the outer flame of the flame of each burner is controlled automatically to be contacted with the bottom of a pot, the optimal heat transfer effect is realized, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of gas cookers, in particular to a gas cooker with a burner head that can be automatically raised and lowered. Background technique [0002] The flame formed by gas combustion can be divided into three layers, which are the flame core, inner flame and outer flame from the inside to the outside. Among them, the flame core is mainly evaporated unburned gas, with the lowest temperature; the inner flame is not fully burned, and its temperature is higher than that of the flame core; the outer flame is in full contact with air, fully burned, and has the highest temperature. [0003] Therefore, when using a gas stove for cooking, the most effective way of heat transfer should be that the outer flame of the flame contacts the bottom of the pot body. [0004] When using a gas stove for cooking, different cooking methods or different stages of cooking require different levels of firepower. The size of the firepower ...

AI Technical Summary

Problems solved by technology

[0005] At present, the distance between the burner (including the fire cover) and the support of the gas stoves on the market is fixed, so when the firepower is adjusted, the height of the flame also changes accordingly. When the fire is low, the outer flame of the flame is far away from the pot The bottom of the body, resulting in low heat transfer efficiency and low energy utilization

[0006] In the published patent documents, there are many technical solutions that can adjust the height of the furnace head or the support to achieve energy saving, but in the disclosed technical solutions, they are all manually adjusted.
