Burner

Abstract

The invention discloses a burner which is high in burning efficiency, stable in burning, simple in structure and low in cost. At least two outer ring ejector pipes (7) are arranged on a burner base (1), each outer ring ejector pipe (7) is communicated with a combustion air mixing chamber (8) inside the burner base (1), an outer ring nozzle (9) is arranged on the periphery of each outer ring ejector pipe (7) in a matched mode, a center nozzle (6) is defined by a center mixing cavity (10), a gap is reserved between the upper edge of the center mixing cavity (10) and the lower edge of a center burner cap (4), the center burner cap (4) and an outer ring burner cap (5) are respectively provided with a flame stabilizing groove (12) which is used for communicating the interior and the exterior, and two parts, located on the upper portion and the lower portion of the flame stabilizing grooves (12), on the center burner cap (4) and the outer ring burner cap (5) are connected through a plurality of reinforcing ribs (13). The burner can be applied to the field of cooking utensils.

Description

technical field [0001] The invention relates to a burner. Background technique [0002] In today's increasingly tight resources, energy conservation has become an important issue. Both electrical appliances and gas appliances are facing this issue. Therefore, improving the thermal efficiency of the burner has become an important direction for the development of the burner. However, due to the limited structure of atmospheric burners currently on the market, there is an obvious bottleneck in their thermal efficiency, and it is generally difficult to exceed 56%. Burners that rarely exceed this efficiency are achieved by adding a concentrator cover and inserting it into the stove. Both of these have their obvious defects. The former is to prevent the heat from spreading outward by adding a metal cover on the outer ring of the burner, but this cover obviously affects the appearance of the entire stove. Therefore, users in the market basically do not accept this kind of cooke...

AI Technical Summary

Problems solved by technology

The defect of the latter is that the entire burner is embedded inside the cooker, which will cause a problem that the heat generated by the burner will accumulate inside the cooker, making the working temperature of each component in the cooker too high. Damage the life of each component, one is that the high temperature will cause danger to the user

This will cause a longer distance between the cooking utensils and the burner, which is not conducive to the improvement of the thermal efficiency of the burner.

[0005] However, since a fixed nozzle has a fixed limit for injecting air, generally speaking, a nozzle with a small aperture has a smaller aperture, and the ratio of injected air to gas will be relatively large.
