Burner cap and stove burner comprising same

Abstract

The invention discloses a burner cap and a stove burner comprising same. The burner cap comprises an annular burner cap body and a cap plate assembly, wherein the outer ring of the cap plate assembly is detachably connected with the upper end of the burner cap body, and the cap plate assembly and the burner cap body are jointly formed into a gas mixing cavity with a downward opening; and an arc-shaped main fire outlet hole extending in the circumferential direction is formed in the outer edge of the cap plate assembly, an annular fire outlet ring is arranged between the cap plate assembly and the burner cap body, and the main fire outlet hole and the fire outlet ring communicate with the gas mixing cavity. The main fire outlet hole is arc-shaped, and the area of the main fire outlet holes is larger than that of a conventional discrete round fire outlet hole, so that the strength of the fire hole is relatively low, the amount of injected primary air is large, and combustion is more sufficient; secondly, the flame distribution of the arc-shaped main fire outlet hole in the circumferential direction is more uniform than that of the conventional discrete round fire outlet hole, so that the heating uniformity and heat absorption of the bottom of cookware are improved favorably; and it is not easy for the wall surface of the arc-shaped main fire outlet hole to adhere to a liquid to cause blocking, and the main fire outlet hole is easy to clean.

Description

technical field [0001] The invention relates to a fire cover and a cooker burner comprising the same. Background technique [0002] At present, the highest performance cooker has a thermal load of 4.5kW and a thermal efficiency of 75%. As the market competition for kitchen appliances becomes more and more fierce, all enterprises are concentrating on the development of cookers with greater firepower, higher thermal efficiency and easy cleaning. . The fire cover is one of the important components of the burner. Usually, the fire cover is located on the burner and communicates with the gas channel in the burner, so as to draw gas (natural gas, liquefied petroleum gas, coal gas, etc.) from the gas channel of the burner. [0003] In the prior art, the top of the fire cover is usually provided with a plurality of discrete circular fire holes to divide the extracted gas into multiple gas columns arranged at intervals. The amount of air is not much, resulting in insufficient gas ...
