Problems solved by technology

[0006] In addition, because the upward air intake burner ejector tube, nozzle, burner fire cover, etc. are located above the panel, so many parts are piled up on the panel, which also brings a lot of trouble to the panel cleaning. There is a problem of nozzle clogging; therefore, it is necessary to design an upward air intake burner, which is easy to clean on the basis of compact structure and improved ejection ability, and can effectively prevent the problems of fire cover clogging and nozzle clogging

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 and figure 2 As shown, the burner in this embodiment includes a liquid pan 1, an air mixing seat 2 and a fire cover. The liquid pan 1 is provided with two separately arranged nozzle seats 6, and each nozzle seat 6 has a first nozzle 61 And the second nozzle 62; the liquid pan 1 is provided with a thermocouple 1a and an ignition needle 1b.

[0034] The air mixing seat 2 is arranged on the upper end surface of the liquid holding tray 1, and the upper end surface of the air mixing seat 2 has an annular inner air mixing groove 22 and an outer air mixing groove 21 positioned outside the inner air mixing groove 22, and the inner air mixing groove 22 has at least Two inner air inlets 221 are opened, and two outer air inlets 211 are opened on the outer air mixing tank 21. The lower end surface of the air mixing seat 2 is pro...

Abstract

A fire cover plate is characterized in that the lower end of the fire cover plate inclines outwards and downwards in the radial direction to form an annular baffle part. Furthermore, the tail end of the baffle part is bent upwards to form an annular liquid containing ring groove. The invention further discloses a combustor. The baffle part can block mixed gas of fuel gas and air, so premixing of the mixed gas before combustion is facilitated, and the uniformity of the concentration field and the speed field of the mixed gas is enhanced.

Description

technical field [0001] The invention relates to a fire cover cover plate, and also relates to a cooker burner, which belongs to the technical field of gas burning equipment. Background technique [0002] Existing cooker burners can be divided into upper air intake burners and lower air intake burners according to the injection method of primary air. The air intake burner has high primary air injection efficiency and sufficient premixing, but it is easy to turn off the flame when the cabinet door is opened and closed, and if the cabinet does not open the air inlet, there will be a hidden danger of insufficient primary air. [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 the injection tube and the mixing chamber is simplified. The primary air, The premixing is...
