A burner for a gas stove

Abstract

The invention relates to a burner for a gas stove, which includes a base; an inner ring fire cover arranged on the base and forming a central air mixing chamber between the base and the base is also arranged on the base, The outer ring fire cover is located on the periphery of the inner ring fire cover and forms an outer ring air mixing chamber with the base, and an air supply chamber is formed between the central air mixing chamber and the outer ring air mixing chamber; it is characterized in that: the outer ring mixing chamber The air chamber is provided with a fire hole along the circumference on the wall adjacent to the air supply chamber, and a guide ring for storing overflow liquid is arranged in the air supply chamber, and the guide ring can divide the air supply chamber into two relatively independent spaces. The fire hole area of ​​the outer ring air mixing chamber and the outer wall area of ​​the central air mixing chamber are respectively connected. Compared with the prior art, the advantage of the present invention is that the guide ring in the air supply chamber can not only store the overflow liquid but also transfer the air supply. The cavity is divided into relatively independent spaces, and the air passes through the separation of the guide ring to form two independent air supply channels, so that both the inner and outer rings can be fully burned.

Description

technical field [0001] The invention relates to the field of household kitchen utensils, in particular to a burner for a gas stove. Background technique [0002] In order to achieve uniform heating of the bottom of the pot, the existing stove burners on the market often change the distribution of fire holes on the inner and outer rings accordingly, such as a Chinese utility model with a patent number of ZL201820258341.2 (authorized announcement number of CN208186341U). The new "top-inlet burner head" includes the burner head, the outer ring fire cover and the center fire cover. The outer ring fire cover has fire holes on the inside and outside of the inner ring fire cover, and the fire holes on the inside and outside of the outer ring fire cover are one-to-one. If the overflow liquid overflows during the cooking process, it can block the fire holes on both sides of the inner and outer sides at the same time. Therefore, a better design is required for the arrangement of the i...

Problems solved by technology

However, this kind of fire cover changes in the axial height, only has fire holes around the outer periphery of the fire cover, and still cannot achieve high firepower, and still does not solve the problem that overflowing liquid easily blocks the fire holes

[0003] In addition, most of the traditional burner fire caps currently on the market are milled with one groove, that is, there is a fire groove milled on the top of the fire cap body. disconnected, it is easy to cause deformation of the fire cover body, thus affecting the ignition effect

For example, the Chinese invention patent "Gas burner with fire transmission device and flameout protection function" whose patent number is 201220464214.0 (notification number is CN202813375U) discloses a similar fire transmission structure. ring fire hole, and the outer ring fire transmission device is also provided on the outer ring fire spray right, the outer ring fire transmission device is a boss installed on the inner wall of the outer ring fire spray ring The outer ring fire transmission hole and the outer ring fire transmission groove on the platform and the outer ring fire spraying ring are composed of the outer ring fire transmission hole and the outer ring fire transmission groove, and the outer ring fire transmission hole and the outer ring fire transmission groove are connected with a The flame-spray holes of the outer ring are connected to realize rapid fire transmission; the fire-transfer channel of this fire-transfer structure is open, and the fire transmission is linear, that is, the fire-transfer channel is exposed on the surface of the outer ring fire cover. This design has a The advantage is that the supply of secondary air in the fire transfer tank is sufficient, and the open fire transfer tank can ensure the supply of secondary air when the flame burns in the fire transfer tank, which is conducive to flame combustion and fire transmission, and has the characteristics of fast fire transmission. However, the open fire transfer tank has two disadvantages. First, the open fire transfer tank is easy to cause blockage of the fire transfer tank. Fire performance, which is also the main reason for the blockage and maintenance of the current fire transmission tank; second, the open fire transmission tank has high requirements on the damper of the stove, because when the damper is opened, too much air at one time will cause the airflow velocity to be too high, resulting in When burning, it is away from the flame or out of fire. Therefore, the structural characteristics of the open fire transfer groove are poor flame stability characteristics. Therefore, to ensure the fire transfer performance of the open fire transfer groove, the damper is basically closed very small, but the damper Turning it down is not conducive to the combustion efficiency of the stove, and it is also not conducive to the emission of smoke, which greatly affects the performance of the stove
