Damper structure and gas stove

Abstract

The invention discloses a damper structure and a gas stove. A plurality of fins are designed on the end surface of a damper plate body, and a primary air inlet is formed between every two adjacent fins. A damper plate moves in the length direction of a nozzle, the lengths of the fins entering an injection pipe are changed, the shielding area of the inner circumferential wall of the injection pipe to the primary air inlets is changed, , so that the primary air introduction amount is changed, stepless adjustment of the primary air introduction amount is achieved, the adjustment range is enlarged, the operation difficulty is reduced, and the actual operation experience is good. Moreover, when the oxygen content in the injection pipe is smaller than a set low threshold value, a controller controls the damper plate to move in the direction away from the injection pipe, so as to increase the primary air introduction amount of the injection pipe, and when the oxygen content in the injection pipe is greater than a set high threshold value, the controller controls the damper plate to move in the direction close to the injection pipe, so as to reduce the primary air introduction amount of the injection pipe, so that the primary air introduction amount is automatically adjusted, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to a damper structure and a gas stove. Background technique [0002] The amount of primary air injection of the existing gas stove determines the combustion conditions of the stove flame. If there is too much primary air, the flame is too short, and there is little contact with the bottom of the pot, and the thermal efficiency is low; , Blurring, yellow flames, etc., CO exceeding the standard seriously. Therefore, the damper structure for adjusting the amount of primary air injection is very important. [0003] Existing gas stoves generally adopt the form of damper adjustment to adjust the primary air injection volume. The damper is matched with the damper fixing plate, and the size of the damper can be adjusted through the protrusions and depressions on the surface. Generally, the outer ring fire and the inner ring fire can be adjusted in 11 gears. see figure 1 As shown, ...

AI Technical Summary

Problems solved by technology

This adjustment method cannot achieve stepless adjustment, and cannot achieve the effect of precisely adjusting the primary air. The adjustment range is too narrow, and the actual operation is difficult.
