A gas cooking stove for Chinese food

Abstract

The invention relates to an improved Chinese cuisine gas cooking stove. The improved Chinese cuisine gas cooking stove comprises a burner and a gas stove shell, wherein the burner is installed in thegas stove shell, the burner is provided with a longitudinal burner shell, the longitudinal burner shell is provided with an inner chamber, a main burner groove and a guide burner groove. By adopting the improved Chinese cuisine gas cooking stove, the flame can be stabilized, the burning efficiency can be improved, especially, by heating the air around the stove body, the uncomfortable taste causedby the ignition of edible oil or food materials due to the direct burning of the combustion flame for the cooked food material can be avoided, the food material cooked in a pot can be enabled to be always in a uniform temperature range, and the fire extinguishing phenomenon can be reduced.

Description

technical field [0001] The invention relates to a gas stove, in particular to an improved gas cooking stove for Chinese food. Background technique [0002] In recent years, with the improvement of people's living standards, the number of household stoves has increased rapidly, and is still increasing at a rate of about 7% per year. In the gas appliance market, gas stoves have become one of the indispensable kitchen appliances for families and occupy a mainstream position. With the continuous research of gas cookers by different manufacturers, the problems caused by the inherent deficiencies in the design and technology of gas cookers have been paid more and more attention by R&D personnel. The main technical problems are as follows: National standards stipulate that the thermal efficiency of embedded gas cookers It is greater than 50%, and the thermal efficiency of desktop gas cookers is greater than 55%. In the actual product development test, the actual test thermal effic...

Problems solved by technology

With the continuous research of gas cookers by different manufacturers, the problems caused by the inherent deficiencies in the design and technology of gas cookers have been paid more and more attention by R&D personnel. The main technical problems are as follows: National standards stipulate that the thermal efficiency of embedded gas cookers It is greater than 50%, and the thermal efficiency of desktop gas cookers is greater than 55%. In the actual product development test, the actual test thermal efficiency of embedded household gas cookers is between 50% and 54% on average (completely premixed burning appliances use infrared combustion principle or use The air blowing method prevents the influence of external convective wind, energy-saving devices that accumulate heat, and advanced embedded and desktop household gas cookers are not included), which is about 5% lower than the actual test thermal efficiency of desktop household gas cookers on average, and the test comparison Calculations show that its heat loss is on average about nine percent higher than that of a table-top domestic gas cooker

Due to the limitation of the design structure, when the embedded gas cooker actually burns, the air supply is always lower than that of the desktop household gas cooker. Therefore, in order to ensure that the CO concentration in the combustion flue gas does not exceed the standard, the design generally has to increase The height of the bracket is to facilitate the supplement of air. Although it ensures that the CO concentration in the combustion flue gas does not exceed the standard, it makes it difficult for the thermal efficiency of the embedded gas stove to reach the standard of the thermal efficiency of the desktop gas stove. This is a development difficulty in combustion technology.
