Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

As shown in fig. 1 and 2, the invention provides a stove fire cover, which comprises an upper cover body 1 and a lower cover body 2 which are arranged in sequence, wherein the upper cover body 1 can be disassembled and assembled relative to the lower cover body 2. The upper surface 21 of the lower cover 2 has a first fire hole 22 communicated with the gas channel 3, the outer wall surface 11 of the upper cover 1 divides the upper surface 21 of the lower cover 2 into a plurality of combustion areas 23, and a gap 24 between the upper cover 1 and the lower cover 2 is also communicated with the gas channel 3 to form a flame stabilizing hole facing the combustion areas 23.

This cooking utensils fire lid passes through outer wall 11 of upper cover body 1 and separates a plurality of relatively independent burning region 23 in the first fire hole 22 room of lower cover body 2 upper surface 21, makes the first fire hole 22 of this cooking utensils fire lid arrange along radial direction to change the uneven phenomenon of heating that current combustor leads to because of two ring type arrangement modes, and each burning region 23 outwards opens, convenient cleanness has reduced the fire hole and has blockked up the probability. Meanwhile, a flame stabilizing hole is formed by a gap 24 between the upper cover body 1 and the lower cover body 2, so that the flame stabilizing effect on the combustion area 23 is improved.

Wherein, a plurality of burning areas 23 are evenly distributed by taking the middle position of the fire cover of the cooker as the center circumference. More preferably, the shape of the upper cover body 1 is a polygonal star shape, that is, the included angle between two adjacent outer wall surfaces 11 of the upper cover body 1 for separating and forming the combustion area 23 is an acute angle, so that the layout of the combustion area 23 can be deeper into the middle position of the stove fire cover, and the surface area of the separated combustion area 23 can also be increased. In the embodiment, the stove fire cover has three combustion areas 23, the three combustion areas 23 are uniformly distributed around the middle position of the stove fire cover, and the upper cover body 1 is correspondingly shaped like a triangle star to enlarge the areas of the three combustion areas 23. Of course, this triangular arrangement is merely a preferred embodiment, and other numbers of combustion zones 23 or arrangements may be used to solve the above problems.

As shown in fig. 2, the upper surface 21 of the lower cover 2 is provided with a plurality of protrusions 25 for positioning the upper cover 1. The protrusion 25 is used to support the upper lid 1 so that the lower surface of the upper lid 1 cannot contact the upper surface 21 of the lower lid 2, thereby forming a flame stabilizing hole. Specifically, when upper cover 1 is mounted on lower cover 2, the entire protruding portion 25 is located directly below upper cover 1 and covered by upper cover 1, so that protruding portion 25 is separated from combustion region 23, and flame in combustion region 23 is prevented from burning protruding portion 25. Meanwhile, in the present embodiment, as shown in fig. 3, the top surface and the side surface of the protruding portion 25 are respectively in contact with the inner wall surface and the inner top surface 12 of the upper lid body 1, so that the upper lid body 1 can be completely positioned on the lower lid body 2 by positioning the plurality of protruding portions 25 with respect to the inner wall surface and the inner top surface 12 of the upper lid body 1, and when the upper lid body 1 is to be separated from the lower lid body 2, it is only necessary to lift the upper lid body 1 upward.

In addition, because the combustion areas 23 in the embodiment are uniformly distributed around the middle position of the fire cover of the cooker, the opening 32 of the gas channel 3 on the surface of the upper cover body 1 is arranged at the middle position, so as to supply gas to the upper cover body 1 while meeting the gas demand for the flame stabilizing hole.

As shown in fig. 4 and 5, the surface of the protruding portion 25 further has a fire transmission row, which is specifically composed of a plurality of fire transmission holes 251 arranged at intervals in sequence, and the fire transmission holes 251 horizontally penetrate through the protruding portion 25 to communicate with the opening 32 of the gas channel 3 located at the middle position of the upper cover body 1, so that the gas is guided to the non-combustion region, i.e. the region directly below the upper cover body 1. By extending both ends of the fire transfer row to two different combustion zones 23, respectively, the function of transferring fire between the different combustion zones 23 is achieved.

Through set up the biography fire row on bulge 25, make to pass the fire row can be hidden in upper cover body 1 below, realize hiding the biography fire function to improve and pass fire stability, and the disguise is better.

As shown in fig. 1 and 2, the first fire holes 22 in each combustion zone 23 are arranged in a uniform arrangement in a specially shaped zone, for example, in the present embodiment, the first fire holes 22 are arranged in a circular zone. Meanwhile, the lower part of the lower cover body 2 is also provided with gas mixing chambers 31 which are arranged corresponding to the combustion areas 23 one by one, the gas mixing chambers 31 are horizontally communicated to the gas channel 3 positioned in the middle of the fire cover of the cooker, so that gas enters the first fire holes 22 through the gas mixing chambers 31, wherein the shapes of the gas mixing chambers 31 correspond to the arrangement shapes of the corresponding first fire holes 22, and the gas outlet quantity among the first fire holes 22 is kept uniform.

In the present embodiment, the pot supports 26 are directly disposed on the stove fire cover, specifically, disposed at the upper surface 21 of the upper cover body 1, and the disposed positions of the pot supports 26 are respectively located between two adjacent combustion areas 23, so as to prevent the flames of the combustion areas 23 from excessively burning the pot supports 26, and at the same time, the heat loss can be reduced. In the present embodiment, the pot holders 26 having a V-shape are disposed at three tip positions of the upper lid body 1 having a triangular star shape, so that a common supporting range of the pot holders 26 is further expanded, so that the pot can be stably placed during use.

In addition, the surface of the outer wall surface 11 of the upper cover 1 is provided with second fire holes 13, as shown in fig. 3, the second fire holes 13 are communicated with the gas channel 3 through an inner cavity positioned inside the upper cover 1, and the second fire holes 13 are arranged towards the direction of the combustion area 23, so as to further increase the heating area and provide different fire combinations. Meanwhile, the second flame holes 13 are disposed right above the slits 24 to stabilize flames using the flame stabilizing holes also formed by the slits 24.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
