High-efficiency burner of blast type gas cooking appliance

Abstract

The invention discloses a high-efficiency burner of a blast type gas cooking appliance. The high-efficiency burner comprises a main burning torch (1), an eternal torch (2) and an air ring (3). The air ring, which is in the shape of an annular groove and surrounds the outer wall of the lower part of the main burning torch, is arranged between the main burning torch and the eternal torch; when the burner works, air flow supplied by a fan enters the air ring through an auxiliary air hole in the lower part of the main burning torch, and then is guided by the air ring to form air jet flow which surrounds the outer wall of the main burning torch, is positioned between the main burning torch and the eternal torch and is jetted upwards; when no iron pan is erected on the gas cooking appliance, the air jet flow does not interfere the normal burning of main burning torch flames and eternal torch flames; when the iron pan is erected, the air jet flow automatically participates in pan bottom mixed torch flames consisting of the main burning torch flames and the eternal torch flames to help burning, so that incomplete burning of the pan bottom mixed torch flames due to oxygen insufficiency is avoided according to the technical scheme. Therefore, the blast type gas cooking appliance achieves the aims of enhancing the burning rate, stabilizing the burning and lowering the content of CO in waste gas.

Description

technical field [0001] The invention relates to a burner for a gas cooker, in particular to a high-efficiency burner for a blast-type gas cooker used in restaurants, canteens, food stalls, and family kitchens for burning gas. Background technique [0002] The burner is the part of the gas cooker that burns gas. The burner of the blast gas cooker is composed of the main torch in the center and the ring-shaped long-burning torch around the main torch. After the iron pot, open the gas valve of the main torch, and the main torch is ignited by the torch flame of the everlasting torch; the key factor that determines whether the gas can be fully burned is the mixing ratio of air and gas. The mixing ratio is adjusted by the damper located at the lower part of the main torch and the air inlet valve and gas valve located at the air inlet of the blower. Among them, the damper has been adjusted in the factory, and the air inlet valve and gas valve can be adjusted by the user, that is, ...

[0002] The burner is the part of the gas cooker that burns gas. The burner of the blast gas cooker is composed of the main torch in the center and the ring-shaped long-burning torch around the main torch. After the iron pot, open the gas valve of the main torch, and the main torch is ignited by the torch flame of the everlasting torch; the key factor that determines whether the gas can be fully burned is the mixing ratio of air and gas. The mixing ratio is adjusted by the damper located at the lower part of the main torch and the air inlet valve and gas valve located at the air inlet of the blower. Among them, the damper has been adjusted in the factory, and the air inlet valve and gas valve can be adjusted by the user, that is, The gas flow ejected from the gas nozzle and the air flow provided by the blower through the damper are mixed in the mixing chamber at the lower part of the main torch, and the mixed gas is burned on the main burner through the main burner to form the main torch flame; if the damper is too large, The main torch flame will be far away from the mai
