Combustor capable of introducing air from top

Abstract

The invention discloses a combustor capable of introducing air from the top. The combustor capable of introducing air from the top comprises a liquid containing disc (1), a gas mixing base (2), a first fire cover (3) and a second fire cover (4), wherein the upper end surface of the gas mixing base (2) is provided with a ring-shaped inner gas mixing slot (22) and an outer gas mixing slot (21) positioned outside the inner gas mixing slot (22). The combustor capable of introducing air from the top is characterized in that a ring-shaped gas blocking ring (7) is arranged in the outer gas mixing slot (21). The gas blocking ring can block a gas mixture which enters the outer gas mixing slot from an outer ejecting tube, facilitates mixing, in the outer gas mixing slot, of the gas mixture, strengthens uniformity of concentration fields and speed fields of the gas mixture, and effectively solves the problem that pre-mixing is insufficient as the ejecting tube of the combustor capable of introducing air from the top is relatively short.

Description

technical field [0001] The invention relates to a cooker burner, which belongs to the technical field of gas burning equipment. Background technique [0002] The existing upper air intake burners can be divided into upper air intake burners and lower air intake burners according to the primary air injection method, wherein the primary air required by the lower air intake burners enters the injection pipe from the bottom of the cooktop, The bottom air intake burner has high primary air injection efficiency and sufficient premixing, but it is easy to turn off the flame when opening and closing the cabinet door, and if the cabinet does not open the air inlet, there will be a hidden danger of insufficient air once. [0003] The primary air required by the upward-inlet burner enters the injection tube from the top of the cooking surface. The limitation of the primary air induction structure of this type of burner requires its overall structure to be compact, and the structure of ...

AI Technical Summary

Problems solved by technology

[0006] In addition, the existing upward air-intake burner has the problem of insufficient premixing of the mixed gas in the air-mixing chamber, and the upward air-inlet burner has the problem that the ejector pipe, nozzle, burner fire cover, etc. of the upward air-inlet burner are all located above the panel. The accumulation of so many parts on the panel also brings a lot of trouble to the panel cleaning, and sometimes there is the problem of nozzle clogging; therefore, it is necessary to design an upward air intake burner, which is compact in structure and improves ejection ability It is easy to clean and can effectively prevent the clogging of the fire cover and the clogging of the nozzle
