Abstract
The utility model relates to a gas stove, in particular to a perpendicular jetting device of a direct-jetting type burner, which comprises an air mixing tube perpendicularly arranged below a gas seat and a fire cover. The lower portion of the air mixing tube is a trumpet structure, an adjustable air door is mounted on the bottom surface of a trumpet opening of the air mixing tube, and at least three spray nozzles are mounted at the bottom of the air mixing tube and are connected with an air delivery pipeline. The spray nozzles which realize multipoint jetting are arranged at the bottom of the air mixing tube, by the aid of the overall design of the direct-jetting type burner, after gas enters the air mixing tube via the spray nozzles, gas jetted by the spray nozzles is respectively sufficiently mixed with nearby air, and mixture is gathered into a main gas flue and is supplied to the burner. The perpendicular jetting device of the direct-jetting type burner has the advantages that discharge volume of carbon monoxide can be reduced effectively while thermal efficiency is greatly improved, and purposes of saving energy and protecting environments can be achieved.
Description
Technical field
The utility model relates to a kind of gas kitchen ranges, particularly a kind of vertical injection apparatus of direct injection combustion device.
Background technology
Popularization along with worldwide energy scarcity and energy-conserving and environment-protective, how the gas kitchen ranges that all relates to as huge numbers of families has become problem that insider generally be concerned about and urgently will solve to reach to energy-conservation maximization by technological innovation, the patent of invention of inventor initiative number is 200520061338.4, denomination of invention is a kind of balanced burner that has, adopt the structure of direct jet supply gas, broken the deficiency that unbalanced and combustion gas of traditional horizontal air feed gas supply and air mix ratio, utilize the relation that temperature is directly proportional with air velocity in the pneumatology, air velocity is accelerated, thereby the high speed wearing and tearing by micel in the combustion gas reach refinement, consequently significantly improved the efficient of burning, saved combustion gas, in continuous use, we also find, traditional jet single injector that adopts has attraction function to the air near nozzle, but it is then not obvious to its effect of air far away, and the mixed discharge capacity that directly has influence on the thermal efficiency and the carbon monoxide of burning than quality of air and combustion gas, therefore, design the rational jet mixed structure that more becomes, could realize better energy-saving effect.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of speed of fuel gas injection faster, with more the become vertical injection apparatus of rational direct injection combustion device of Air mixing.
The technical solution of the utility model is: a kind of vertical injection apparatus of direct injection combustion device, comprise the mixing wind tube of vertical means in burned gas base, fire lid below, described mixing wind tube bottom is loudspeaker structure, in the bell-mouthed bottom surface of mixing wind tube adjustable air door is housed, in the bottom of mixing wind tube at least 3 nozzles are housed, described each nozzle is connected with air delivering pipeline.
Further: said nozzle is 3, comprising a central nozzle and be the side nozzle that symmetry is laid in central nozzle.
Further: said nozzle is 4, comprising a central nozzle and be the side nozzle of Chinese character pin-shaped laying.
The utility model is owing to adopted the nozzle that multi-point injection is set in the mixing wind tube bottom, master-plan in conjunction with the direct injection combustion device, after combustion gas enters mixing wind tube by plurality of nozzles, the combustion gas that its each nozzle sprayed respectively with its near air fully mix, import main airway and supplied burner then, its effect is when can significantly improving the thermal efficiency, reduces the discharge capacity of carbon monoxide effectively, reaches the purpose of not only energy-conservation but also environmental protection.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model general illustration.
Fig. 2 is the schematic diagram of 3 nozzles for the utility model.
Fig. 3 is the schematic diagram of 4 nozzles for the utility model.
The specific embodiment
The utility model such as Fig. 1, Fig. 2, shown in Figure 3, a kind of vertical injection apparatus of direct injection combustion device, comprise the mixing wind tube 3 of vertical means in burned gas base 1, fire lid 2 belows, described mixing wind tube 3 bottoms are loudspeaker structure, in mixing wind tube 3 bell-mouthed bottom surfaces adjustable air door 4 is housed, in the bottom of mixing wind tube 3 at least 3 nozzles 5 are housed, described each nozzle 5 is connected with air delivering pipeline.
Said nozzle 5 is 3, comprising a central nozzle 51 and be the side nozzle 52 that symmetry is laid in central nozzle 51.
Said nozzle 5 is 4, comprising a central nozzle 51 and be the side nozzle 52 of Chinese character pin-shaped laying.
In addition, more smooth and easy for making fuel gas injection, the above-mentioned bell-mouthed angle of fuel gas injection direction and mixing wind tube 3 bottoms that is laid near the side nozzle 52 the central nozzle 51 is close.
Need to prove that what the utility model was suitable for is the direct injection combustion device, no matter the burned gas base of burner, fire lid adopt which kind of structure and fire lid flame burning form, as long as adopted multi-jet structure all should be considered as falling into protection domain of the present utility model.
