Description

Household gas utensils are used the two spray burners of air intake

Technical field

The utility model relates to a kind of burner that is configured in the built-in home gas kitchen ranges, is a kind of two spray burners of air intake of going up specifically.

Background technology

At present, the non-upper inlet wind type burner of the general employing of the built-in home gas kitchen ranges of selling on the market, there is following shortcoming in it: 1. embedding the position is sealed construction, must on the kitchen range panel, air inlet be set, so that entering embedding inside, position, air provide burning required primary air to burner, if two spray burners, the passage that replenishes the required auxiliary air of inner ring fire also must be set on the kitchen range panel, so cause panel can't implement sealing, dirts such as soup are easy to enter kitchen range inside, influence the service life of kitchen range; 2. traditional non-upper inlet wind type burner adopts iron casting to form usually, be subjected to the restriction of process conditions, the dimensional accuracy and the surface quality of burner are wayward, cause actual combustion parameter and designing requirement to exist than big-difference, and also show bigger discreteness aspect combustibility.

Utility model ZL200320122881.1 discloses a kind of full upward air intake twin-jet nozzle burner, it is made of external ring fire cover, interior ring fire lid, burner assembly, end cup assembly, inside and outside inlet channel and corresponding outer shroud fire-fighting mouth and interior ring fire nozzle separately arranged in the end cup assembly, be the horizontal type injector with outer shroud fire-fighting mouth corresponding position straightway in the end cup assembly, the horizontal type injector communicates with the burner combustion chamber after connecting mixed gas passage.Though this utility model has adopted the upper wind inlet type nozzle, its poor sealing, burning quality is not high.

Summary of the invention

The utility model provides a kind of household gas range to use the two spray burners of air intake, can solve the sealing of built-in home gas kitchen ranges effectively, improves kitchen range combustibility and combustion stability.

A kind of household gas utensils are used the two spray burners of air intake, the upper and lower chassis that comprises inside and outside burner and joint, inside and outside burner includes burner and bell, top bottom-disc is provided with inner burner fuel gas inlet and corresponding inner burner nozzle, top bottom-disc and low bottom-disc cooperation are provided with outer burner fuel gas inlet and corresponding outer burner nozzle, correspondingly between described chassis be provided with horizontal induction tunnel with the outer burner nozzle, described horizontal induction tunnel deviates from the center chassis setting, and the mixed gas outlet through being located on the top bottom-disc communicates with the outer burner burner.

Described mixed gas outlet is 3.

The upper surface outer ring of described top bottom-disc is provided with a mounting plane and some screws.

Described inside and outside burner and upper and lower chassis are formed by the heatproof aluminium alloy compression casting.

Advantage of the present utility model is:

1, inside and outside burner is the independently combustion system of atmospheric burning type mode, burn required primary air and auxiliary air all obtains from kitchen range table top superjacent air space, air duct need be set on the kitchen range panel, be convenient to implement sealed kitchen range shell mechanism, can prevent that soup and dirt from entering kitchen range inside, help kitchen range and safeguard, also can make full use of the panel upper space simultaneously and realize the multi-combustor configuration;

2, the induction tunnel that adopts in the outer burner deviates from the center chassis setting, can reduce the injection resistance effectively, and is combined with three exit passageway structures, can make the pressure distribution of burner head even, helps improving burning quality;

3, the top bottom-disc of burner is provided with a mounting plane and some screws, is used to connect the gas kitchen ranges panel, can realize better sealing effectiveness.

4, the size and dimension at the primary air of inside and outside burner inlet position has good uniformity in batch process, air door regulating mechanism need be set, and avoids effectively regulating improper cause burner imperfect combustion or tempering because of air door regulating mechanism;

5, the burner of inside and outside burner and upper and lower chassis adopt aluminum alloy die-casting technological die casting to form, the dimensional accuracy and the surface quality of burner improve a lot than conventional burners, for depth optimization combustion parameter, raising combustibility index and combustion stability provide adequate condition;

The specific embodiment

Shown in Fig. 1,3, a kind of household gas range is used the two spray burners of air intake, comprise inside and outside burner and upper and

lower chassis

5,6, top bottom-disc 5 and low bottom-disc 6 engage, the upper surface outer ring of top bottom-disc 5 is provided with a mounting plane 16 and some screws 17, is used to connect the gas kitchen ranges panel, can realize better sealing effectiveness, inner burner comprises bell 1 and burner 4, and outer burner comprises bell 2 and burner 3.

Fig. 4 and Fig. 5 be respectively among Fig. 2 B-B to, C-C is to generalized section, as shown in the figure, be provided with inner burner fuel gas inlet 8 and corresponding inner burner nozzle 9 in the top bottom-disc 5, top bottom-disc 5 and low bottom-disc 6 cooperations are provided with outer burner fuel gas inlet 10 and outer burner nozzle 11, correspondingly with inner burner nozzle 9 be provided with vertical induction tunnel, vertical induction tunnel directly links to each other with inner burner burner 4, deviate from chassis 5 with outer burner nozzle 11 corresponding being provided with, the horizontal induction tunnel 12 that 6 centers are provided with, horizontal induction tunnel 12 connects the mixed gas passage 7 of annular, three mixed gas outlets 15 of mixed gas passage 7 on top bottom-disc 5 communicate with outer burner burner 3, adopt the structure of horizontal induction tunnel 12 of above-mentioned offset and three outlets, 15 passages in the outer burner, can reduce the injection resistance effectively, and make the pressure distribution of burner head even, help improving burning quality.
