All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that all the directional indicators in the embodiments of the present application are only used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture, and if the specific posture is changed, the directional indicators are correspondingly changed.
The following disclosure provides many different embodiments, or examples, for implementing different structures of the application. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the application. Furthermore, the present application may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.
The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:
the working principle of the gas stove is as follows: high-pressure gas (natural gas or liquefied gas) enters a valve body of the gas stove from a gas pipeline, after the valve body is opened, the high-pressure gas flows into a nozzle, the size of the nozzle is small and is generally smaller than 2mm, the high-pressure gas flows out from the nozzle and becomes high-speed low-pressure gas, the high-pressure gas enters a venturi structure of a burner to form negative pressure (lower than atmospheric pressure), so that primary air is injected and flows into the burner, the primary air and the gas are mixed and then flow out from the burner into a gas distribution disc and a fire cover for combustion, secondary air is supplemented for the second time in the environment in the combustion process, and the complete combustion of the gas is ensured.
From the working principle, the primary air quantity and the secondary air quantity are core key factors for ensuring complete combustion of fuel gas. In the case of the existing gas range combustion system, the fuel gas is mixed with the primary air before combustion, so that the primary air is considered to be substantially completely involved in the reaction, and the secondary air is not completely involved in the reaction due to buoyancy and entrainment of the high-speed jet of fuel gas during combustion. On the premise of ensuring complete reaction of fuel gas, the total air quantity should be reduced as much as possible, and the heat released by the combustion reaction is reduced to heat redundant air so as to improve the heat efficiency.
At present, the secondary air in the gas stove is generally and mainly supplemented by optimizing a fire hole structure, increasing the contact area of the fire hole and air, and effectively and quickly supplementing the secondary air is difficult, especially when a smoke outlet is reduced, the secondary air supplementing is more difficult, a better combustion state cannot be realized, and the exceeding of smoke can be caused.
That is, the above-described method of increasing the amount of secondary air does not allow the fuel gas to be completely combusted in an optimal state, and there is room for improvement.
Based on the technical problems, the embodiment of the application provides a gas distribution plate, a burner and a gas stove, which aim to improve the supplementary quantity of secondary air at least to a certain extent and enable gas to be completely combusted in an optimal state as far as possible.
