Description

Infrared burner for household gas stove

【Technical field】

The invention relates to an infrared burner for a household gas stove.

【Background technique】

The infrared burner used in household gas stoves is mainly composed of the inner and outer air chambers of the burner connected with the ejector tube at the lower part and the infrared ceramic radiation sheet installed on the upper opening of the inner and outer air chambers. Since the burner adopts the principle of complete premixed combustion, When the ceramic sheet is heated to a high temperature above 800 degrees, it can convert a large amount of heat energy into infrared radiation energy, so it has the advantages of energy saving, environmental protection and no pollution. The traditional burner adopts an integral structure design, and the ceramic sheet is bonded or fixedly connected to the upper opening of the inner and outer air chambers. When the burner needs to be repaired, the entire burner needs to be taken to a professional repair department for repair, so installation and repair are very difficult. very troublesome. In addition, the traditional ceramic sheet is in direct contact with the furnace body. After the ceramic sheet reaches a high temperature of 800 degrees, the temperature of the furnace body will also be very high. Over time, the furnace body will deform and cause air leakage, which will affect the service life of the burner.
