Abstract

The utility model discloses an external fire cover of a cookware combustor, which comprises a main body. The main body is composed of a main body top ring tray, a bottom ring tray and rib sheets. A levorotatory or dextral flame path is formed between two adjacent rib sheets. The special points of that the external fire cover are as follows: the external fire cover further comprises a decorative ring, the decorative ring and the main body top ring tray are formed in one time, and a ring-shaped table which is arranged on the top ring tray at the junction position between the decorative ring and the main body top ring tray is matched with the axial end part of an external ring plate of a fuel gas groove of a cookware head. As the above structure is adopted, when in assembling and disassembling, the main body and the decorative ring are formed in one time, and the assembling and disassembling are convenient; the radial outer wall of the main body top ring tray is connected with the decorative ring in a one-time forming manner, so as to effectively prevent the cracking and deforming of the top ring tray and the bottom ring tray, and prolong the service life.

Description

The outer fire cover of cooker burner

Technical field

The utility model relates to a kind of device of cooker burner, especially the outer fire cover of cooker burner.

Background technology

Present prior art, Chinese patent ZL200520061452.7, title: gas burner lid, it comprises body, as shown in Figure 1 and Figure 2, described body is made of apical ring dish 1, base ring dish 2 and fin 3, constitutes the quirk 4 of left-handed or dextrorotation between adjacent two fins, and the opening 41 of whole apical ring dish 1 thickness of the perforation that communicates with quirk 4 is arranged on the inner surface of apical ring dish 1.During use, the inner ring surface of base ring dish 2 cooperates with fuel tank inner ring plate inner ring surface.Existing problems are: (one) at first will install case ring on being assembled to the stove burner time, refills body then and cooperates with fuel tank on case ring, the burner, and assembling, dismounting are inconvenient; (2) in use, long-term burning can cause the fracture or the distortion of apical ring dish, base ring dish.

Summary of the invention

The purpose of this utility model is: a kind of outer fire cover of cooker burner is provided, and it not only assembles, convenient disassembly, and can prevent the fracture or the distortion of apical ring dish, base ring dish effectively, increases the service life.

The utility model is achieved in that a kind of outer fire cover of cooker burner, comprise body, describedly constitute by body apical ring dish, base ring dish and fin, constitute the quirk of left-handed or dextrorotation between adjacent two fins, its special character is: also comprise a case ring, the apical ring dish one-shot forming of case ring and body is made; There is an annular table to cooperate on the apical ring dish of case ring and the apical ring dish intersection of body with the outer ring plate axial end portion of the fuel tank of burner.

The outer fire cover of described cooker burner, its special character is: also comprise an annular support ring, the base ring dish one-shot forming of described annular support ring and body is made.

The outer fire cover of described cooker burner, its special character is: described annular support ring is made of radially ring flat-plate, axial rings tube, and the axial section of annular support ring is dihedral.

The outer fire cover of described cooker burner, its special character is: also have some on the annular support ring and the corresponding air guide groove of quirk.

The outer fire cover of a kind of cooker burner of the utility model, owing to adopt such structure, when assembling, dismounting, because assembling, convenient disassembly are made in body and case ring one-shot forming; The radial outer wall and the case ring one-shot forming of the apical ring dish of body are linked together, and can prevent the fracture or the distortion of apical ring dish, base ring dish effectively, have prolonged service life.

The specific embodiment

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

As shown in Figure 3, Figure 4, a kind of outer fire cover of cooker burner comprises body, describedly constitute by body apical ring dish 1, base ring dish 2 and fin 3, constitute the quirk 4 of left-handed or dextrorotation between adjacent two fins 3, also comprise a case ring 5, case ring 5 is made with apical ring dish 1 one-shot forming of body; Have an annular table 11 to cooperate with the outer ring plate end of the fuel tank of burner on the apical ring dish 1 of case ring 5 and apical ring dish 1 intersection of body, promptly annular table 11 cooperates with the axial end of outer ring plate.

As further improvement, also comprise an annular support ring 6, described annular support ring 6 is made with base ring dish 2 one-shot formings of body.Adopt such structure, under the situation that does not change fuel tank specification, size on the burner, can increase the volume of the cavity that apical ring dish 1, base ring dish 2 and fin 3 surround; The one, can increase the number of quirk 4; The 2nd, can enlarge the distance between quirk and the quirk, thereby increase amount of supplied air, make fuel gas buring more abundant, improve the thermal efficiency.

As Fig. 5, shown in Figure 6 as described in annular support ring 6 constitute by radially ring flat-plate 61, axial rings tube 62, the axial section of annular support ring 6 is dihedral.In use, the inner ring surface 621 of annular support ring 6 cooperates with fuel tank inner ring plate inner ring surface.Described fuel tank inner ring plate inner ring surface, promptly inner ring plate is positioned at the anchor ring of fuel tank.

Also have some on the annular support ring 6 and quirk 4 corresponding air guide grooves 63.
