Abstract

The utility model belongs to an improved fire cover for gas kitchen range which includes cover body with outer convex plate and inner convex plate in the distribution of double-ring, a quadrate fuel gas slotted-hole on the outer convex plate and several circular fuel gas slotted-holes on the inner convex plate. The cover will enlarge the fire area of the pan, and the flame will rotate in the same direction, thereby improving thermal efficiency of fuel gas and effectively resolving the problem of increase of harmful gas caused by lacking of secondary air in inner ring space at the same time.

Description

A kind of combustion gas stove lid

Technical field

The utility model relates to gas-cooker accessory technical field, particularly a kind of improved combustion gas stove lid.

Background technology

At present, the combustion gas fire slotted eye that popular combustion gas stove covers on the market mostly is microscler shape or toroidal.The former is commonly called as spiral flame cover by the fire lid, and this type of fire lid (being monocycle or dicyclo) generally all can exist fiery slotted eye length long, causes problems such as flame is long, auxiliary air deficiency easily; Latter's fire lid is commonly called as straight fire fire lid, also exist easily from flame, with inhomogeneous, the not high shortcoming of the thermal efficiency of the bottom of a pan fire area.For above-mentioned reasons, so that numerous producer is difficult to develop the high kitchen range of heat flow.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of thermal efficiency height, even with the bottom of a pan fire area, and can effectively reduce the double ring fire cover of pernicious gas (as CO) concentration.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of combustion gas stove lid comprises lid, it is characterized in that described lid is provided with several outer lug boss and inner convex platform, and described outer lug boss and inner convex platform are double-ring and distribute, and all is provided with combustion gas fire slotted eye on each boss.

As the utility model improvement of the technical scheme, all combustion gas fire slotted eyes all are positioned at the boss same side and shape differs; Combustion gas fire slotted eye is microscler shape on the outer lug boss, and combustion gas fire slotted eye is a toroidal on the inner convex platform.

As the utility model further improvement in the technical proposal, the centroclinal angle of capping is between 22 °～28 °.

As the further improvement of the utility model technique scheme, inner convex platform is a triangle along the cross section on the circumference, and combustion gas fire slotted eye is made up of several circular holes on its side.

The beneficial effects of the utility model are: the lid inside loop and outside loop is provided with the boss that varies in size; And to be provided with the combustion gas fire slotted eye that shape differs on the boss same side, make all combustion gas fire slotted eye flames be same direction rotation, and fire lid capping can make gas stop for a long time under the bottom of a pan to centroclinal certain angle with combustion-gas flow, and completing combustion, improved the combustion gas thermal efficiency; Each combustion gas fire slotted eye can be evenly distributed on the fire lid capping on the boss, has strengthened the bottom of a pan fire area; Especially ring combustion gas fire slotted eye can be used toroidal instead in, in the double ring fire cover on the market in the microscler shape combustion gas fire slotted eye used of ring boss significant improvement is arranged, can solve more thoroughly that the not enough pernicious gas that brings of auxiliary air increases problem in the interior annular space; And ingenious microscler shape and two kinds of combustion gas fire of the toroidal slotted eye that has utilized in traditional fire lid of this fire lid, outward appearance is beautiful, and is novel unique.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a generalized section of the present utility model;

Fig. 3 is the A-A line of vision enlarged drawing of Fig. 1;

Fig. 4 is the B-B line of vision enlarged drawing of Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, combustion gas stove lid of the present utility model, comprise lid 1, on lid 1, be provided with several outer lug boss 2 and inner convex platform 3, and outer lug boss 2 and inner convex platform 3 are double-ring and distribute, be equipped with combustion gas fire slotted eye 4 on each boss, combustion gas fire slotted eye 4 all is positioned at the boss same side and shape differs, and makes the flame that comes out from combustion gas fire slotted eye be same direction rotation with combustion-gas flow like this, and gas stops under the bottom of a pan for a long time, and completing combustion, improved the combustion gas thermal efficiency.

Combustion gas fire slotted eye 4 is microscler shapes on the outer lug boss 2, and combustion gas fire slotted eye 4 is toroidals on the inner convex platform 3, and the capping of lid 1 is preferably disposed between 22 °～30 ° to the angle of inclination beta angle at center.

With reference to Fig. 4, inner convex platform 2 is a triangle along the cross section on the circumference, and combustion gas fire slotted eye 4 preferably is made up of two circular holes on its side.Certainly, combustion gas fire slotted eye 4 can be made up of plural circular hole on its side, but circular hole is unsuitable too much, too much may produce auxiliary air deficiency in the overlapping or interior annular space of flame, all can cause harmful gas concentration such as CO to increase.

Claims
