A damper adjustment mechanism for a gas cooker

Abstract

The invention relates to a damper adjustment mechanism for a gas cooker, which includes an injection pipe, a nozzle seat and a nozzle installed on the nozzle seat, the nozzle of the nozzle faces the air inlet end of the injection pipe, and is characterized in that: It includes an air guide installed on the nozzle seat, and the air guide can move relative to the air inlet end of the ejector tube along the axis of the ejector tube; the air guide includes a body, and the center of the body has a The central hole in which the nozzles are aligned, the body also has at least two guide parts arranged at intervals around the central hole along the circumferential direction, the interval between adjacent guide parts forms a primary air channel for guiding primary air, which is similar to the existing Compared with the prior art, the advantage of the present invention is to provide a new air guide, the center of the air guide is gas, and the guide parts are arranged at intervals along the circumference of the air guide body, which can realize the primary air to rotate around the gas , and then promote the rapid mixing of gas and primary air before the gas inlet end of the injection tube.

Description

technical field [0001] The invention relates to the field of household kitchen utensils, in particular to a damper adjustment mechanism for a gas cooker. Background technique [0002] Most of the existing cooker burners on the market are atmospheric burners, which need to pre-mix part of the primary air, which requires a damper primary air passage size adjustment device to adjust the amount of pre-mixed primary air required. At present, there are two most common methods: one is to change the effective circulation area of ​​the primary air suction port by rotating the air regulating plate and moving the air regulating plate back and forth, thereby adjusting the suction volume of the primary air; this form of air regulating When the air regulating plate reaches the ejection tube, it continues to rotate in the direction of the ejecting pipe, which will cause the air regulating plate to be stuck and not easy to rotate; the second is that the air regulating plate is fixed on the ...

AI Technical Summary

Problems solved by technology

Among them, the air nozzle is located inside the mixing cylinder, and the size of the damper is controlled by an air regulating mechanism. The main disadvantages are as follows: 1. The nozzle is located inside the mixing cylinder, and the heat dissipation is not good. The heat of the mixing cylinder is easily transferred to the nozzle. During the cooking process , the load of the nozzle is easily affected; 2. The nozzle is located inside the mixing cylinder. During the long-term cooking process, when the inner ring has soup entering the mixing cylinder, it is easy to cause the nozzle to be blocked (although the soup can flow from the through hole connected to the mixing cylinder and the air) out, but when the opening of the air regulating mechanism is small or large, it is still easy to cause blockage); 3. The ability of the nozzle to inject air needs to be strengthened, and the existing structure has a greater resistance to air injection; 4. This damper The adaptability of the adjustment method is poor. When the damper is closed very small, the air cannot be supplied, resulting in insufficient combustion
