Problems solved by technology

[0003] Although the burner with a single gas mixture chamber structure solves the basic working condition requirements of a stove, it has the defects of unstable combustion and low thermal efficiency due to the narrow range of pressure changes in front of the gas stove and uneven mixing. In the state of high and low pressure changes in front of the stove, it is easy to cause tempering and abnormal combustion.

Abstract

The invention relates to a double-cavity burner used on gas appliances, in particular to the double-cavity burner used on family gas embedded type kitchen utensils and complete premix infrared kitchen utensils. The double-cavity burner comprises an ejecting tube and a multi-hole heat emitting body, wherein the double-cavity burner further comprises a first air mix cavity body, a second air mix cavity body and a connecting device. The ejecting tube is communicated with an air inlet of the first air mix cavity body. The connecting device is communicated with an air outlet of the first air mix cavity body and an air inlet of the second air mix cavity body. An outlet of the second air mix cavity body is communicated with the heat emitting body. The double-cavity burner enables gas to be mixed with air for a plurality of times so that substance is more evenly mixed with energy and therefore fully combustion of the gas receives benefits, emission of waste gas is reduced, burning efficiency is improved, influence in combustion by changes of gas pressure is enabled to be small and avoiding unstable combustion of the gas. The double-cavity burner solves the technical problems of low heat efficiency, high waste gas emission, narrow pressure change range before a stove and unstable combustion.

Description

Technical field: [0001] The invention relates to a double-cavity burner used on a gas appliance, in particular to a double-chamber burner used on a household gas built-in cooker and a fully premixed infrared cooker. technical background: [0002] Present large-scale gas ranges and common infrared gas ranges all just use a single air chamber to mix gas, and burn the mixed gas through a ceramic sheet or a fire cover. Such as figure 1 The schematic diagram of the structure of the ceramic chip infrared burner and figure 2 The schematic diagram of the structure of the atmospheric burner is shown. The structure of this burner includes an ejector tube 1 , a burner cavity 2 and a ceramic sheet or a fire cover 5 . Their common feature is that they only include one gas mixing chamber, and air and gas are mixed in the gas mixing chamber through the intake passage, and burn on the heating element at the outlet of the gas mixing chamber. [0003] Although the burner with a single gas...
