Abstract

The utility model relates to a burner, which comprises an outer ring ejecting pipe, an inner ring ejecting pipe, a mixing cavity, an upper cover of the mixing cavity, a stove head and a fire cover. In the utility model, the stove head is provided with an inner annular groove and an outer annular groove which are concentric; the inner side and the outer side of each annular groove is both provided with a plurality of fire hole grooves; the two ejecting pipe are respectively communicated with an inner annular cavity body and an outer annular cavity body which are in the mixing cavity and are mutually isolated; the cavity bodies are respectively communicated with the inner annular groove and the outer annular groove. The utility model forms four circles of concentric flame after being ignited, flame forms three heating areas inside and outside the burner, the center position of the burner especially forms a heating area, and thereby, the utility model overcomes the defects of uneven heating and especial no flame heating on the center area of cookers existing in traditional burners and has the advantages of high heating efficiency and energy availability and uniform fire power distribution.

Description

A kind of burner

1. technical field

The utility model is a kind of parts of domestic gas kitchen range, especially a kind of burner.

2. background technology

The burner of present gas-cooker mostly has only two ring fire flames, and firepower mainly is distributed in outer shroud flame, when therefore the burner of this gas-cooker heats cooker, firepower all is dispersed in the outside, when particularly using circular bottom pot to make cooker, concentration of food to be heated is in the centre of pot, and the central area in the bottom of a pan can not get good heating, so the efficiency of heating surface to food is not high, capacity usage ratio is not high yet.

3. summary of the invention

The burner that provides a kind of efficiency of heating surface and capacity usage ratio height, firepower to be evenly distributed is provided the purpose of this utility model.

The technical scheme that realizes the utility model purpose is: it includes outer shroud induction tunnel, interior ring induction tunnel, hybrid chamber, hybrid chamber loam cake, burner, Huo Gai, on burner, be provided with inside and outside two concentric annular grooves, the fire lid is divided into external ring fire cover and interior ring fire lid, covers respectively on inside and outside two concentric annular grooves.The inside and outside both sides of every annular groove are equipped with some fire hole grooves, and two induction tunnels communicate with mutual isolated inner and outer rings cavity in the hybrid chamber respectively, and cavity communicates with outer annular recess and inner annular recess respectively.

The fire hole groove that fire hole groove of inwardly offering in the utility model on the inner annular recess and outer annular recess are outwards offered is interspersed; And the medial and lateral fire hole groove in the same annular groove is distributed in same footpath upwards.

Inside-and-outside ring groove in the utility model is annular or ring-type polygon.

Good effect of the present utility model is that combustion gas enters inside and outside two concentric annular grooves on the burner respectively by cavity, spray from the fire hole groove at last, light the back and form 4 circle concentric flames, these flames form 3 heating regions inside and outside burner, particularly form a heating region in the centre of whole burner, thereby it is inhomogeneous to have overcome the conventional burners heating, particularly the cooker central area does not have the defective of flame heat, has the advantages that the efficiency of heating surface and capacity usage ratio height, firepower are evenly distributed.

4. description of drawings

Accompanying drawing 1 is a front view of the present utility model;

Accompanying drawing 2 is vertical views of accompanying drawing 1;

Accompanying drawing 3 is front views of burner of the present utility model;

Accompanying drawing 4 is A-A cutaway views of accompanying drawing 3;

Accompanying drawing 5 is front views of the hybrid chamber of burner;

Accompanying drawing 6 is vertical views of accompanying drawing 5.

5. the specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

From accompanying drawing 1 and accompanying drawing 2, interior ring induction tunnel 2 of the present utility model and outer shroud induction tunnel 1 embed respectively in the hybrid chamber 3.Hybrid chamber loam cake 4 covers on the hybrid chamber 3, and both connect with flat head screw; Hybrid chamber loam cake 4 is responsible for carrying mist to the burner 5 that covers thereon simultaneously.Offer two annular grooves on the burner 5--inner annular recess 8 and outer annular recess 9, annular groove promptly can be an annular, it also can be the ring-type polygon, the inside and outside both sides of these two grooves all offer some fire hole grooves 10 radially, these fire hole grooves 10 are evenly distributed on the groove, form concentric 4 groups.Groove top is provided with the fire lid, comprises interior ring fire lid 7 on the outer annular recess 9 and the external ring fire cover 6 on the inner annular recess 8, and the fire lid combines with the fire hole groove and forms fire hole, and finally combustion gas will spray from these fire holes and burn.

Can see that in accompanying drawing 3 and accompanying drawing 4 the interior ring fire hole slot of inner annular recess 8 and the outer shroud fire hole of outer annular recess 9 do not make progress in same footpath, be interspersed that the fire hole groove in the same groove then is distributed in same footpath upwards.

In accompanying drawing 5 and accompanying drawing 6, interior ring cavity body 11 and outer shroud cavity 12 are separated, and the centre also is separated relatively independent position simultaneously, can be used to install flame-out protection device.
