Metal honeycomb energy-gathering air-saving burner for gas stove

Abstract

The invention relates to a metal honeycomb energy-gathering air-saving burner for a gas stove. The burner provided by the invention comprises a burner body, an injection tube, and a gas mixing chamber, wherein the inner cavity of the upper part of the gas mixing chamber is provided with a metal honeycomb infrared burning plate which is formed by a strip-shaped plain film and a strip-shaped ripple film through staggered stacking or winding or twining, the inner ring and outer ring of the metal honeycomb infrared burning plate are provided with fixed rings. The burner provided by the invention is characterized in that the strip-shaped plain film and the strip-shaped ripple film have molded bent structure in the height direction, the shape of the fixed ring is matched with that of a surface contacted with the metal honeycomb infrared burning plate; the middles of the bent structures, in the height direction, of the strip-shaped plain film and the strip-shaped ripple film are provided with at least more than 1 local bent part, and the bent structures are integrally bent from top to bottom. Based on the structure, the burner provided by the invention has the advantages that the safety performance is better, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of gas stove manufacturing, and in particular relates to a metal honeycomb energy-gathering and gas-saving burner for a gas stove. Background technique [0002] The ceramic plate honeycomb or metal honeycomb infrared burner has the advantages of high thermal efficiency, sufficient combustion, and less harmful gas produced during the combustion process, which meets the current and future needs of the field of energy conservation and environmental protection. However, the currently used ceramic board honeycomb body combustion board is impact-resistant and easy to break. After a period of use, it will be weathered, repeated thermal expansion and contraction, easy to burst or break, thus affecting the normal use of the entire stove, and sometimes even causing backfire and deflagration phenomenon, leading to serious safety accidents. Therefore, the gas cooker of the ceramic honeycomb infrared burner has always a...

Problems solved by technology

However, the currently used ceramic board honeycomb body combustion board is impact-resistant and easy to break. After a period of use, it will be weathered, repeated thermal expansion and contraction, easy to burst or break, thus affecting the normal use of the entire stove, and sometimes even causing backfire and deflagration phenomenon, leading to serious safety accidents

Therefore, gas stoves with ceramic honeycomb infrared burners have always affected the promotion and application of civilian infrared gas stoves. Up to now, the market share in the entire civilian gas stove market is still less than 5%.

In 2007, the applicant applied for a utility model patent named "a composite infrared burner" (notification number CN201170553Y). The technical solution is based on the requirements of the metal honeycomb three-way catalytic carrier widely used in automobiles (motorcycles) , combined with the technical requirements of the civil infrared gas stove manufacturing technology and national standards and regulations, a honeycomb infrared combustion panel with various shapes on the surface or in the middle is designed, which can effectively avoid the occurrence of broken and burst phenomena, but after several years of development Summary of use found that since the current metal honeycomb infrared combustion board 4 is generally formed by stacking or winding or winding long strip flat sheets and long strip corrugated sheets, when the gas stove is repeatedly heated and cooled, the metal honeycomb body Laminated or coiled or entangled elongated flat sheets and elongated corrugated sheets are prone to protrude (emerge) or sink locally, causing the gas stove to backfire or fail to use normally, and it is easy to cause the danger of backfire. , when the burner is working, the heat reflection generated by the bottom of the pot will enter the burner through the straight-through honeycomb holes (such as figure 1 shown), increase the internal temperature of the burner and the chance of tempering, and there are potential safety hazards

Based on the above shortcomings, it is difficult for the metal honeycomb infrared combustion panels of the existing civilian infrared gas stoves on the market to meet the structural and safety performance stability indicators, which seriously affects the popularization and use of civilian infrared gas stoves that meet the requirements of energy conservation and environmental protection.
