Abstract

The invention discloses a burner ring, a burner and a gas appliance. The burner ring is used for the burner. The burner ring comprises a burner ring body and an infrared combustion carrier; the burnerring body comprises an annular peripheral wall and a top wall connected with the annular peripheral wall, and the infrared combustion carrier is arranged above the top wall; the annular peripheral wall and the top wall jointly form a gas mixing chamber, and the top wall is provided with through holes communicating with the gas mixing chamber and the infrared combustion carrier; a buffer chamber is formed between the top wall and the infrared combustion carrier, and the buffer chamber is in communication with the through holes; the gas mixing chamber is used for containing mixed gas of gas andair; and the burner ring is configured to allow the mixed gas to enter the buffer chamber from the gas mixing chamber through the through holes to form a reflux region in the buffer chamber. According to the burner ring, the buffer chamber is arranged between the top wall and the infrared combustion carrier, and the mixed gas forms the reflux area in the buffer chamber so that the backfire risk can be reduced, the flow velocity field of the mixed gas is improved, infrared combustion is stabler, and the load on the burner ring can be increased.

Description

technical field [0001] The invention relates to the technical field of gas appliances, in particular to a fire cover, a burner and a gas appliance. Background technique [0002] Burners are divided into ordinary burners and infrared burners according to their combustion methods. The infrared burner increases the infrared combustion carrier in the fire cover, so that the heat of the burner is radiated in the form of infrared rays, and the heat exchange efficiency is high, which can improve the combustion efficiency. In the infrared burner in the related art, the gas directly enters the infrared combustion carrier for combustion. This combustion method is prone to flashback, and the load of the burner is difficult to increase. Contents of the invention [0003] The embodiment of the present invention provides a fire cover, a burner and a gas appliance. [0004] The fire cover according to the embodiment of the present invention is used for a burner. The fire cover includes...
