Combustor for gas stove

Abstract

The invention relates to a combustor for a gas stove. The combustor comprises a first flame cover, and the first flame cover comprises a flame cover body. A first air mixing cavity is formed among theannular top wall of the flame cover body, and an inner ring wall and an outer ring wall which vertically extend downwards from the inner side edge and the outer side edge of the annular top wall. Thecombustor is characterized by further comprising a lower sealing plate capable of covering the bottom of the first air mixing cavity; and the lower sealing plate can move relative to the first flamecover, and the area of an opening, for allowing mixed air to be input, of the lower sealing plate is changed. Compared with the prior art, the combustor has the advantages that due to the fact that afirst air mixing chamber formed by the lower sealing plate and the first flame cover is designed to be of a split structure, and cleaning is convenient; and meanwhile, the lower sealing plate can moverelative to the first flame cover to achieve the gas outlet area of mixed gas in the first flame cover, the first flame cover large in gas outlet area is suitable for liquefied gas and other gas sources high in heat value, and the first flame cover small in gas outlet area can be suitable for natural gas, artificial gas and other gas sources low in heat value.

Description

technical field [0001] The invention relates to the field of gas cookers, in particular to a burner. Background technique [0002] The gas burner of the existing domestic gas cooker includes a gas mixing chamber, a first fire cover, an ejector tube, etc., wherein the gas mixing chamber of the burner is a very important part of the cooking range, and the function of the gas mixing chamber is to mix the gas so that the gas Mix with the primary air more evenly; supply secondary air to the inner ring at the same time, the current integrated fixed structure of the gas mixing chamber is not conducive to the cleaning of the cooker, especially the inside of the gas mixing chamber and the inside of the waist-shaped hole, the user is not easy to clean the gas mixing chamber There are also more and more complaints, such as the Chinese utility model patent "A Burner" with the patent number ZL201420072885 (the announcement number is CN2037314112U), or if the patent number is ZL2006100523...

[0002] The gas burner of the existing domestic gas cooker includes a gas mixing chamber, a first fire cover, an injection pipe, etc., wherein the gas mixing chamber of the burner is a very important part of the cooking range, and the function of the gas mixing chamber is to mix the gas so that the gas Mix with the primary air more evenly; at the same time supply the secondary air to the inner ring, the current one-piece fixed structure of the gas mixing chamber is not conducive to the cleaning of the cooker, especially the inside of the gas mixing chamber and the inside of the waist-shaped hole, the user is not easy to clean the gas mixing chamber There are also more and more complaints, such as the Chinese utility model patent "A Burner" with the patent number ZL201420072885 (the announcement number is CN2037314112U), or if the patent number is ZL200610052382.8 (the announcement number is CN1884911A) all disclose similar Such a mixed air chamber, in addition, supplies secondary air by supplying air from the waist-shaped hole of the air mixed chamber to the inner ring, but the reduction effect on the smoke of the inner ring is still very limited, and it is also necessary to adjust the air mixing chamber to the inner ring. The air supply effect is further improved
