A fire cover for a gas stove and a burner using the fire cover

Abstract

The invention relates to a fire cover for a gas cooker and a burner using the fire cover, comprising a fire cover body, an annular top wall of the fire cover body and inner and outer edges of the annular top wall A gas mixing chamber is formed between the inner ring wall extending vertically or obliquely downwards and the outer ring wall, and it is characterized in that: the outer ring wall includes at least two spaced along the circumference of the fire cover body, and The outer ring fire outlets connected to the gas mixing chamber, each outer ring fire outlet is radial as a whole, and each outer ring fire outlet has fire outlet holes distributed along the radial direction of the fire cover body at intervals. Compared with the prior art, this The advantage of the invention is that at least two outer ring fire outlet bodies are arranged at intervals in the circumferential direction of the fire cover body, and the fire outlet holes distributed along the radial direction on each outer ring fire outlet body can realize the fire cover body in the circumferential direction. To better surround the bottom of the pot in two dimensions, radial and radial, to achieve the purpose of evenly heating the bottom of the pot.

Description

technical field [0001] The invention relates to the technical field of household kitchen utensils, in particular to a fire cover for a gas stove and a burner using the fire cover. Background technique [0002] At present, the fire cover of the gas stove is usually composed of a top wall, an annular inner wall and an annular outer wall. Several main fire holes are arranged on the annular outer wall of the fire cover along its circumferential direction. The wall only includes a single row of fire holes. This type of patent literature can refer to the Chinese utility model patent "A Conical Fire Cover for a Gas Stove Burner" (authorized announcement number CN2842216Y) whose patent number is ZL200520014838.2. The reference patent No. is ZL201120246965.0 Chinese utility model patent "a kind of burner fire cap" (authorized announcement number is CN202149492U).

Problems solved by technology

The single main fire hole combustion method disclosed above has the disadvantages that the flame is easy to jump after combustion and the combustion area is unstable. At the same time, the single row of fire holes not only makes the combustion heat efficiency of the gas stove low, but also makes the combustion of the gas insufficient, resulting in carbon monoxide The discharge of gas has aggravated environmental pollution. For this reason, the Chinese utility model patent "A Gas Stove Fire Lid Assembly" (authorized announcement number CN206191590U) with the patent number of ZL201621153770 discloses a gas stove fire cover assembly, which includes a base 1. A cover body adapted to the base, the inner side wall of the cover body is arranged with a number of inner fire holes along its surrounding direction, and the outer side wall of the cover body is arranged with a double row of outer fire holes along its circumferential direction. The holes include a number of first outer fire holes in the first row and a number of second outer fire holes in the second row. The first outer fire holes and the second outer fire holes are arranged alternately. Fire holes, and the first outer fire holes and the second outer fire holes are arranged alternately, the setting of the double row of fire holes effectively improves the combustion efficiency of the gas stove, but the diameter of the outer peripheral fire formed by the double rows of fire holes is the same to heat the pot The range is the same, so the uniformity of heating the pot with the fire cover with double rows of fire holes is poor

[0003] In addition, the existing burner fire cover adds a waterproof eaves above the fire hole in order to prevent the overflow from blocking the fire hole, and the structure of the waterproof eaves can refer to the applicant's patent number ZL201820760029.3 (authorized announcement number CN208804674U) The Chinese utility model patent "A Fire Cover Structure for a Stove Burner" includes a fire cover, the outer surface of the fire cover is provided with main fire holes distributed along the circumferential interval, and the outer edge of the fire cover extends outward to form a shield The first waterproof eaves above the main fire hole, although the first waterproof eaves can prevent the overflow from blocking the main fire hole, but the first waterproof eaves will also press down on the flame formed by the main fire hole, and then affect the main flame. Overall combustion thermal efficiency of the fire hole
