Description

A gas stove fire cover assembly

technical field

The utility model relates to the technical field of gas stoves, in particular to a fire cover assembly of a gas stove.

Background technique

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. 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 the emission of carbon monoxide gas, which aggravates environmental pollution and endangers the health of users.

Contents of the invention

The purpose of the utility model is to provide a gas stove fire cover assembly which has a simple and reasonable structure and can improve gas combustion efficiency in view of the defects and deficiencies of the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions.

A gas stove fire cover assembly described in the utility model includes a base, a cover adapted to the base, an air chamber is formed between the base and the cover, and the inner side wall of the cover is along its circumferential direction A number of inner fire holes are arranged, and the outer wall of the cover is arranged with double rows of outer fire holes along its circumferential direction, and the double rows of outer fire holes include several first outer fire holes located in the first row, and several The second outer fire hole, the first outer fire hole and the second outer fire hole are arranged alternately; the top of the cover body is provided with a fire ignition groove in the radial direction, and one end of the fire ignition groove extends to the inner side wall, so that The other end of the fire pilot groove extends to the outer wall.

Further, the opening of the inner fire hole is inclined upward.

Further, the inner side wall is provided with a first annular cone surface, the ring diameter of the first annular cone surface gradually decreases from top to bottom, and the inner fire hole penetrates through the first annular cone surface.

Further, the openings of the first outer fire hole and the second outer fire hole are inclined upward.

Further, the outer wall is provided with a second annular cone surface, the ring diameter of the second annular cone surface gradually increases from top to bottom, the first outer fire hole, the second outer fire hole through the second annular tapered surface.

Further, the distance between any two adjacent first outer fire holes and the second outer fire holes is equal.

Further, the hole radius ratio of the second outer fire hole to the first outer fire hole is 1:1.5-1:2.

Further, the radius of the first outer fire hole is equal to that of the inner fire hole.

The beneficial effects of the utility model are: the utility model sets double rows of outer fire holes on the outer wall, the first outer fire holes and the second outer fire holes are arranged alternately, which effectively improves the combustion efficiency of the gas stove, and makes the gas burn More fully, reducing environmental pollution.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 3, a gas stove fire cover assembly described in the present utility model includes a base 1 and a cover 2 adapted to the base, and the base 1 and the cover 2 form a There is an air chamber, and the gas is led to the air chamber through the gas pipeline. The inner side wall 3 of the cover body 2 is arranged with several inner fire holes 31 along its circumferential direction, and the outer side wall 4 of the described cover body 2 is arranged with a double row of outer fire holes along its circumferential direction. Several first outer fire holes 41 in one row, and several second outer fire holes 42 in the second row, the first outer fire holes 41 and the second outer fire holes 42 are arranged alternately, which improves the combustion thermal efficiency; the cover The top of the body 2 is radially provided with a fire guiding groove 5 , one end of the fire guiding groove 5 extends to the inner side wall 3 , and the other end of the fire guiding groove 5 extends to the outer side wall 4 .

The opening of the inner fire hole 31 is inclined upwards, and the inner side wall 3 is provided with a first annular cone surface 32, the ring diameter of the first annular cone surface 32 gradually decreases from top to bottom, and the The inner fire hole 31 runs through the first annular conical surface 32; the openings of the first outer fire hole 41 and the second outer fire hole 42 are inclined upward, and the outer wall 4 is provided with a second annular conical surface 43. The ring diameter of the second annular cone surface 43 gradually increases from top to bottom, the first outer fire hole 41 and the second outer fire hole 42 penetrate through the second annular cone surface 43, The combustion thermal efficiency of the gas stove is further improved, and the combustion of the gas is made more fully.

The distance between any two adjacent first outer fire holes 41 and second outer fire holes 42 is equal, and the hole radius ratio between the second outer fire holes 42 and the first outer fire holes 41 is 1:1.5-1 : 2, the hole radius of the first outer fire hole 41 is equal to that of the inner fire hole 31, and the size of the hole diameter is set to make the gas burn more fully.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
