Abstract

The utility model provides an improve distributor seat that secondary air flows, it includes outer loop gas tank, outer loop admit air interface, the fiery cage that is located bedplate center, axial air flue and radial secondary air passageway, interior fiery cage link up the bedplate, and there is a step the radial inboard of outer loop gas tank's inner ring wallboard, there is axial secondary air air guide hole circumference on the step, the center of axial secondary air air guide hole circumference and the center of axial air flue circumference are on a radius line. Owing to adopt such structure, secondary air gets into through radial secondary air passageway on the one hand, and the on the other hand warp beam is to the entering of secondary air air guide hole circumference, thereby form the radial inboard that secondary air encircleed interior fiery cage and outer loop gas tank, thereby guarantee that secondary air is sufficient, gas combustion is abundant, energy -conservation.

Description

A kind of flame separating device seat improving secondary air flowing

Technical field

The utility model relates to cooker burner, the flame separating device seat of especially a kind of cooker burner.

Background technology

Currently available technology, the flame separating device seat of a kind of cooker burner, it comprises outer shroud fuel tank, outer shroud intake interface, the inner fire cover seat being positioned at seat board center, axial air flue and radial secondary-air passage; The through seat board of inner fire cover seat, axial air flue is between adjacent two secondary-air passage. Existing problems are: the secondary air between inner fire cover seat and outer shroud fuel tank is not enough, and fuel gas buring is insufficient.

Practical novel content

The purpose of this utility model is: providing a kind of flame separating device seat improving secondary air flowing, it has and has secondary air abundance, the feature of sufficient combustion.

The utility model is achieved in that a kind of flame separating device seat improving secondary air flowing, and it comprises outer shroud fuel tank, outer shroud intake interface, the inner fire cover seat being positioned at seat board center, axial air flue and radial secondary-air passage; The through seat board of inner fire cover seat, its special character is: the radially inner side of the inner ring wallboard of outer shroud fuel tank has a step, and described step has axial secondary air gas port circumference;

The center of axial secondary air gas port circumference and the center of axial air flue circumference are in a radius.

Described a kind of flame separating device seat improving secondary air flowing, its special character is: there are some spreader plates the upper end of described inner fire cover seat, and the radially inner side of spreader plate intersects.

A kind of flame separating device seat improving secondary air flowing of the utility model, owing to adopting such structure, secondary air enters through radial secondary-air passage on the one hand, on the other hand entering through axial secondary air gas port circumference; Thus form secondary air around the radially inner side of inner fire cover seat and outer shroud fuel tank; Thus ensureing that secondary air is sufficient, fuel gas buring is abundant, energy-conservation.

Embodiment

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

As shown in Figure 1, a kind of flame separating device seat improving secondary air flowing, it comprises outer shroud fuel tank 1, outer shroud intake interface 2, the inner fire cover seat 3 being positioned at seat board center, axial air flue 4 and radial secondary-air passage 5; The through seat board 6 of inner fire cover seat 3; Radial secondary-air passage 5 is between adjacent two axial air flues 4. The radially inner side of the inner ring wallboard of outer shroud fuel tank 1 has a step 7, and described step 7 has the 71 of axial secondary air gas port circumference;

Axial secondary air gas port 71 circumference center and the center of axial air flue 4 circumference in a radius.

There are some spreader plates 8 upper end of described inner fire cover seat 3, and the radially inner side of spreader plate 8 intersects, radial outside is connected with the inwall of inner fire cover seat 3.

Seat board 6 also has igniting pin hole 61, inductive needle or thermocouple hole 62.

Above-described is only preferred embodiments of the present utility model. It should be appreciated that for the person of ordinary skill of the art, when not departing from the utility model principle, it is also possible to make some improvement and modification, this is also considered as protection domain of the present utility model.
