Air door adjusting mechanism used for gas cooking appliance

Abstract

The invention relates to an air door adjusting mechanism used for a gas cooking appliance. The air door adjusting mechanism comprises an injection pipe, a nozzle seat and a nozzle which is mounted onthe nozzle seat, the nozzle opening of the nozzle faces the air inlet end of the injection pipe, and the air door adjusting mechanism is characterized in that the air door adjusting mechanism furthercomprises an air guide part which is mounted on the nozzle seat; the air guide component can move relative to the air inlet end of the injection pipe in the axis direction of the injection pipe; and the air guide component comprises a body, a central hole aligned with the nozzle is formed in the center of the body, the body is further provided with at least two guide parts arranged around the central hole at intervals in the circumferential direction, and a primary air channel used for guiding primary air is formed by an interval between every two adjacent guide parts. Compared with the priorart, the air door adjusting mechanism has the advantages that the novel air guide component is provided, fuel gas is discharged from the center of the air guide component, and the guide parts are arranged in the circumferential direction of the air guide component body at intervals, so that the fact that primary air can rotate on the periphery of the fuel gas is achieved, and then the fuel gas andthe primary air are promoted to be rapidly mixed on the gas inlet end of the injection pipe firstly.

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
