Abstract
The utility model relates to a fire cover used for a gas stove, comprising a ring-shaped fire cover body, wherein the fire cover body is evenly provided with a plurality of fire holes along the periphery; the plurality of fire holes comprise first part fire holes and second part fire holes; the first part fire holes are close to the gas outlet of a gas chamber under the fire cover body; the second part fire holes are far away from the gas outlet; and the size of the first part fire holes is smaller than that of the second part fire hole. Compared with the prior art, the fire cover leads the size of the fire hole close to the gas outlet of the gas chamber to be smaller than that of the fire holes far away from the gas outlet, therefore, corresponding to the gas pressure distribution, the fire holes corresponding to large gas pressure are small and the fire holes corresponding to small gas pressure are big, then the size of the whole-ring flame on the fire cover is even in actual combustion, thus realizing the even heating on the pot bottom.
Description
Technical field
The utility model belongs to the technical field of gas-cooker, relates in particular to a kind of fire lid that is used for gas-cooker.
Background technology
At present, operated by rotary motion has these two fire lids of external ring fire cover and inner ring fire lid in the burner of gas-cooker, external ring fire cover generally ringwise, fire covers along circumference and offers a plurality of fire holes uniformly.Have inner ring fuel chamber and outer shroud fuel chamber in the burner, inner ring fire lid and external ring fire cover just cover in the outlet of corresponding fuel chamber respectively, interior induction tunnel and outer induction tunnel that inner ring fuel chamber and outer shroud fuel chamber below are connected with respectively, wherein, the combustion gas of outer induction tunnel output is passed through the outlet of outer shroud fuel chamber and is entered into external ring fire cover one side, after lighting a fire successfully, flame spreads all over whole external ring fire cover and burns from a side of external ring fire cover.But when reality is used, because the combustion gas of induction tunnel output must have certain pressure, for whole external ring fire cover, the gaseous-pressure that is positioned at the exit of outer shroud fuel chamber is greater than and is positioned near gaseous-pressure around the exit, like this, there is this phenomenon during burning inevitably, promptly, the intensity of a fire in exit that is positioned at outer shroud fuel chamber on the external ring fire cover is more many greatly than near the zone around it, this will cause the flame on the external ring fire cover inhomogeneous to the bottom of a pan heating, influences dish overall taste and nutrition.Thereby existing fire lid requires further improvement.
The utility model content
Technical problem to be solved in the utility model is that a kind of fire lid that is used for gas-cooker that can realize evenly heating is provided at the present situation of prior art, and when it can guarantee to burn, that circle flame intensity of a fire size that annular fire covers evenly.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the fire lid of gas-cooker, include ringwise fire lid body, fire lid body upper edge circumference offers a plurality of fire holes uniformly, it is characterized in that: a plurality of fire holes comprise first's fire hole and second portion fire hole, first's fire hole is near the gas outlet of fire lid body below fuel chamber, the second portion fire hole is away from gas outlet, and the size of first's fire hole is littler than second portion fire hole.
Preferably, the size of first's fire hole can be 1/2～2/3 of a second portion fire hole.
Each fire hole can cover the grooved hole of this inside and outside side or common circular hole for running through fire, is more convenient for processing for the fire lid, and described fire hole is preferably the grooved hole.
During for ease of actual installation, the fire hole of first can be placed on the gas outlet top of fuel chamber like clockwork, and the fire hole that makes first is near gas outlet, and the bottom of described fire lid body can be provided with a locating hole.During use, outer shroud fuel chamber surface in the burner is provided with the pilot pin of projection in the relevant position, be inserted into the locating hole of fire lid body bottom when pilot pin after, the fire hole of first just just in time is positioned at the gas outlet top of fuel chamber, is convenient to the user and correctly is in place apace.
Compared with prior art, advantage of the present utility model is: by a plurality of fire holes are divided into first and second portion, and first's fire hole is littler than second portion fire hole, the fire hole size of the gas outlet of feasible close fuel chamber is less than the fire hole size away from gas outlet, so, distribute for gaseous-pressure, the fire hole that corresponding gaseous-pressure is big is little, and the little fire hole of corresponding gaseous-pressure is big, thereby when Actual combustion, the whole circle flame intensity of a fire size that fire covers is even, thereby realizes the even heating to the bottom of a pan.This design of the present utility model is specially adapted to adopt the one-time formed fire of grooved fire hole to cover, and processes very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the fire lid that this is used for gas-cooker includes ringwise fire lid body 1, and fire lid body 1 upper edge circumference offers a plurality of fire holes 2 uniformly;
Wherein, each fire hole 2 is the grooved hole, a plurality of fire holes 2 are formed (part of being included except first's fire hole 21 among Fig. 1 promptly all is a second portion fire hole 22) by first's fire hole 21 and second portion fire hole 22, first's fire hole 21 is near the gas outlet of fire lid body 1 below fuel chamber, 22 of second portion fire holes are relatively away from gas outlet, and the size of first's fire hole 21 is littler than the fire hole of second portion 22, in the present embodiment, first's fire hole 21 is 1/2 sizes of second portion fire hole, and promptly first's fire hole 21 areas of section are 1/2 of second portion fire hole 22 areas of section;
In addition, the bottom of described fire lid body 1 is provided with a locating hole 11, when reality is used, outer shroud fuel chamber surface is provided with the pilot pin of projection in the relevant position, during actual installation fire lid, after making pilot pin be inserted into the locating hole 11 of fire lid body 1 bottom, the fire lid just settles at one go and is installed on the outer bad fuel chamber, and is very convenient.
