Abstract

The utility model relates to a gas cooker for cooking Chinese meal. The utility model comprises tubular ejectors, an inner ring burner of an upper covers, a pan stand 1 and a table top 2; the upper part of the upper cover is provided with annular air accumulation plates. The utility model is characterized in that the sectional area ratio of the outer ring ejector 3 and the outer ring ejector 3' is one to two the sectional areas of the inner and outer air accumulation plates 4 and 4' are convergent along the direction of gas flow; the ends of fire holes 6 and 6' which are arranged on the upper covers 5 and 5' of the inner and outer rings form a paraboloid; the skirt section of the pan stand 1 and the upward punching cuff portion of the table top 2 are buckled in no-touch type according to child and mother openings. The utility model solves the problems of the prior art of fire power dispersal, backfire and inconvenient maintenance.

Description

Gas-combusting stove for Chinese meal

The utility model relates to a kind of gas-cooker, in particular for the gas cooking stove of culinary art Chinese meal dish, belongs to the cooking stove of gaseous fuel.

The gas cooking stove of existing culinary art Chinese meal dish has been continued to use the structure of house coal gas kitchen, fire hole on its inside and outside gas collection dish distributes at grade, cause firepower to disperse, the sectional area of gas collection dish inner chamber is along gas-flow direction no change, tempering easily, filling with insulation material and bonding together between pan bracket and the table top, the inconvenience maintenance.

The purpose of this utility model provides the Chinese meal gas-cooker that a kind of firepower was concentrated, was difficult for tempering, is convenient to keep in repair.

The purpose of this utility model is achieved in that a kind of Chinese meal gas-cooker is by the Internal and external cycle burner with comprise that the stove of pan bracket, table top forms.Each burner includes the tubulose injector, is connected opened upper end annular gas collection dish that communicates and the loam cake that snaps onto the uniform fire hole in border on the gas collection dish with injector.The ratio of the sectional area of Internal and external cycle injector is approximately 1:2, and the top baseline of inside and outside gas collection dish keeps level, and the bottom baseline begins to be inclined upwardly from air inlet, makes the sectional area of gas collection dish along gas-flow direction convergent; The axis of the fire hole that covers on the Internal and external cycle tilts inwards, and the end of all fire holes forms a parabola; The skirt section of pan bracket and metal platform are pressed mother-son mouth contactless type snapping towards last piercing and flanging portion.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structure chart of gas collection dish and loam cake in the utility model;

Fig. 2 is the structure chart of injector in the utility model;

Fig. 3 is pan bracket and a table top connection diagram in the utility model.

Chinese meal gas-cooker shown in the figure is by the Internal and external cycle burner and comprise that the stove of pan bracket 1, metal table top 2 forms, the annular gas collection dish of the opened upper end that each burner includes the tubulose injector, is connected with injector and communicates, snaps onto the loam cake of the uniform fire hole in border on the gas collection dish.In Fig. 1 and Fig. 2, inner ring injector 3 and outer ring injector 3 ' the ratio of sectional area be 1:1.8～2.2, so that adapt to the quantity situation of Internal and external cycle fire hole, both suction sides 7 and 7 ' flush (this point is improvements over the prior art, so that casting technique is simple).Interior gas collection dish 4 and outer gas collection dish 4 ' the top baseline still keep level, the bottom baseline begins to be inclined upwardly from air inlet, such structure makes the sectional area of gas collection dish along gas-flow direction convergent.Internal and external cycle loam cake 5 and 5 ' on fire hole 6 and 6 ' axis be inclined upwardly inwards, the end of all fire holes distributes by parabolic, the axis normal of each fire hole is in this parabola.In Fig. 3 the skirt section of pan bracket 1 and metal table top 2 upwards piercing and flanging portion press mother-son mouth contactless type snapping, utilize the heat insulation of between the two the air gap realization stove.

In the utility model, because the gas collection dish adopts the structure of cross section convergent, therefore air mixture is evenly distributed, prevented tempering phenomenon; Because fire hole distributes by parabolic, so make that flame focuses on, firepower is concentrated; Because pan bracket and metal table top have adopted simple snapping mode, so not only solve the heat-insulating problem of stove effectively in addition, also be convenient to the maintenance of stove simultaneously.

Claims
