Problems solved by technology

[0004] It can be seen from the above that most of the burners in the prior art only have a two-ring structure. When cooking, the temperature between the two rings is low, resulting in uneven heating of the bottom of the pot, which affects the actual cooking experience; Complicated, when the burner overflows or after a period of use, the middle of the burner is not easy to clean, resulting in the accumulation of dirt and affecting the user experience. In severe cases, it will even aggravate the corrosion of the burner and reduce the service life of the burner

Embodiment 1

[0028] see Figure 1 ~ Figure 4 , a household gas cooker burner, comprising a base 1, a base cover 2 sequentially arranged above the base 1, a gas mixing seat 3 and a fire cover 4, and an injection pipe, which is used to introduce gas, and the Gas and primary air are fully mixed according to a certain ratio to achieve full combustion effect.

[0029] The base 1 communicates with the injection tube, and the mixed gas introduced by the injection tube enters the base 1 , and the injection tube includes an inner injection tube 51 and an outer injection tube 52 .

[0030] The base cover plate 2 covers the top of the base 1, the base cover plate 2 includes a cover plate 23, and an inner gas channel 21 and an outer gas channel 22 arranged on the cover plate 23, the inner gas channel 21 and the inner injection pipe 51 The outer gas channel 22 communicates with the outer injection pipe 52 . In this embodiment, both the inner gas passage 21 and the outer gas passage 22 are hollow cyli...

Embodiment 2

[0038] see Figure 5 , In this embodiment, the difference from the first embodiment above is that the inner ring fire holes 412 are evenly distributed in a certain circular area of ​​the inner ring fire cover 41 on the top wall 43 . The fire hole adopts this distribution method, the diameter of the fire hole is 1.0-1.4mm, the total area of ​​the fire hole is large, avoiding tempering, can improve the primary air coefficient, and burn stably, the depth of the fire hole is not more than 2mm, preferably Between 0.5mm and 1.5mm, to avoid blockage of the fire hole in case of overflow, etc., and at the same time, it is easy to clean.

Embodiment 3

[0040] see Figure 6 , in this embodiment, the difference from the second embodiment above is that the second side wall 411 of the inner ring fire cover 41 is higher than the first side wall 421 of the outer ring fire cover 42, and at this time the top of the inner ring fire cover 41 The part of the wall 43 and the part of the top wall 43' of the outer ring fire cover 42 are no longer integrated, and the part of the top wall 43 is higher than the part of the top wall 43'. This can make the inner ring fire hole 412 closer to the bottom of the pot. In order to prevent the bottom of the pot from touching the fire cover 4 when using a pointed pot bottom, the second side wall 411 of the inner ring fire cover 41 is higher than the outer ring fire cover 42 The height of the first side wall 421 is not more than 15mm.

Abstract

The invention discloses a domestic gas cooker burner. The domestic gas cooker burner comprises a pedestal, an ejection tube, a gas mixing base and a burner cap, wherein the gas mixing base and the burner cap are arranged above the pedestal. The gas mixing base comprises an inner gas mixing chamber and an outer gas mixing chamber which both communicate with the ejection tube. The burn cap covers the upper portion of the gas mixing base, and an inner ring fire hole and an outer ring fire hole are formed in the corresponding positions of the inner gas mixing chamber and the outer gas mixing chamber. The domestic gas cooker burner is characterized in that the inner gas mixing chamber is located at the central position of the gas mixing base, and the outer gas mixing chamber is located between at least two extending arms which extend outwards from the inner gas mixing chamber; and meanwhile, the burner cap has a shape matched with the extending arms. The gas mixing base and the burner cap of the burner are arranged to be in the shape of extending outwards by the at least two extending arms from the center, so that flames have large secondary air contact area, CO emission can be better lowered, and the heat efficiency of the burner can be improved.

Description

technical field [0001] The invention relates to kitchen equipment, in particular to a burner for a household gas stove. Background technique [0002] Gas stoves are commonly used kitchen utensils in people's daily life. Gas stoves are mainly divided into stoves that burn liquefied combustible gas as fuel. The liquefied combustible gas can be natural gas, liquefied petroleum gas, biogas, etc. There are many kinds, such as liquefied gas stove, gas stove, natural gas stove and so on. Of course, gas stoves can also be divided into single stoves, double stoves, single-eye stoves, multi-eye stoves, and desktop embedded stoves according to different structures. [0003] The burner is an important part of the gas stove. At present, the burner structure of the domestic gas stove is mostly a circular structure, and the combustion is in the form of a multi-ring flame. For example, the Chinese patent application number 200610122586.4 discloses a gas cooker burner with upward air intak...
