Abstract

The utility model relates to a linkage blast kitchen appliance system of a straight guide tube combustion-supporting type, which comprises a furnace shell (1) and a furnace disk (2) arranged on the shell (1). The furnace shell is connectedly provided with a combustion-supporting blast pipe (33) and a gas pipe (53). The gas pipe (53), after passing through the furnace, is directly connected with the furnace disk (2). Particularly, the bottom of the furnace disk (2) is vertically provided with a straight combustion-supporting pipe (21) which is a little higher or lower than a gas outlet. The device uses the straight pipe to guide blast producing upward wind power and lead burning flame upwards when gas is fully mixed with air so that the gas remains in the furnace in a shorter time to further improve burning efficiency, reduce energy consumption and pollution emission. The utility model adopts the linkage operation of air and gas to gain high burning efficiency and reduction of cooking time. Meanwhile, the amount of blast can also be reduced so as to lower noises and save electricity, genuinely achieving the saving of gas, time and electricity as well as reducing noises and pollution emission.

Description

Straight-tube type burning-assist interlock air blast kitchen range device

Technical fieldThe utility model belongs to a kind of non-family expenses formula kitchen range, belongs to air blast combustion-supporting high heat effect, oligosaprobic kitchen range especially.

Background technologyCommercial kitchen range are widely used in the catering industry, because its heating power is big, on fire violent, can satisfy the needs in catering industry and public institution dining room and popular.But this kitchen range common problem is combustion gas mix with air incorrect, the consumption gas many, efficient is low, noise is big, imperfect combustion and the discharge CO content big, contaminated environment.

On stove dish sidewall, have the whirlwind air admission hole through preliminary improved commercial kitchen range, non-arranged radially is adopted in this hole, be partial to same direction, and bottom hole is big, upper hole is little, wishes to form cyclone effect by air blast strength, finishes mixing of air and combustion gas in the burner zone, improve efficiency of combustion, thereby reduce the discharging of imperfect combustion dusty gas.

Though can improve the mixability of combustion gas during the beginning of the kitchen range of this prior art, but the whirlwind of its formation rests on the overlong time in the burner hearth, only the thrust that increases generation by the volume of the lift of the hot-air after the burning and rotary air makes flame upwards advance to the bottom of a pan, cause the flame impulse force not smooth, also increased simultaneously the generation of unburnt gas, the thermal efficiency still can not improve.Simultaneously, for being increased, heating power strengthens the blow rate required, the airborne noise aggravating working environment that the noise of air blast produces with rotary combustion, unfavorable cooking operation.

Summary of the invention the utility model is that the above-mentioned weak point that overcomes prior art proposes a kind of straight-tube type burning-assist air blast kitchen range, produce wind-force upwards by the guiding of the straight tube in burner hearth air blast, above when fully mixing, burned flame being guided into, minimizing is in the delay of burner hearth, thereby improves efficiency of combustion, cut down the consumption of energy, reduce disposal of pollutants; Air and combustion gas combined operation, the efficiency of combustion height, the cooking time shortens, thus the blow rate required also can reduce and reduces noise, saves electric weight, really accomplishes province's gas, save time, power saving, and noise reduction, blowdown are low simultaneously.

The purpose of this utility model can reach by adopting following technical measures:

Design, a kind of straight-tube type burning-assist interlock of manufacturing air blast kitchen range device comprise furnace enclosure and the stove dish that is arranged on this shell; Described furnace enclosure tipping has combustion-supporting blast pipe and Gas Pipe; Described Gas Pipe is directly joined with described stove dish after passing burner hearth; The bottom of especially described burner hearth dish vertically is equipped with directly draws combustion tube; This combustion tube is slightly high or a little less than the gas outlet height.

Brief Description Of Drawings:

Fig. 1 is the overall construction drawing of the utility model straight-tube type burning-assist interlock air blast kitchen range device.

The specific embodimentBelow in conjunction with accompanying drawing in detail most preferred embodiment of the present utility model is described in detail.

A kind of straight-tube type burning-assist interlock air blast kitchen range device comprises furnace enclosure 1 and the stove dish 2 that is arranged on this shell 1; Described furnace enclosure bottom and side-wall hole, tipping has combustion-supporting blast pipe 33 and Gas Pipe 53 respectively; Described Gas Pipe 53 is directly joined with described stove dish 2 after passing burner hearth; Bottom centre is provided with combustion gas nozzle 54 at the stove dish, and this nozzle is provided with combustion gas fluid dividing cover 55.The bottom of especially described stove dish 2 vertically is equipped with directly draws combustion tube 21; This combustion tube is slightly high or a little less than the gas outlet height.

Usually, kindling material circle 62 is installed on the stove dish 2, kindling material pipe 61 passes burner hearth and the stove dish is struck sparks in kindling material circle 62; Rim 72 also is installed on the kindling material circle 62, thicker heat-resisting thermal insulation layer 71 is arranged in it.

Described stove dish 2 bottoms and sidewall also have auxiliary air hole 22; Total breathing area in this auxiliary air hole 22 is about described 1/2nd to 1/4th of combustion tube 21 breathing areas that directly draw.Side outlet is higher than outer inlets in the described sidewall auxiliary air hole 22.

Among the embodiment, the described combustion tube 21 that directly draws can be arranged to two circles on the chassis of stove dish 2 in addition, is the low setting in the high outer ring of inner ring.In the present embodiment, three circles are set directly draw combustion tube 21, inside and outside circle is a little more than gas outlet, and centre circle is lower slightly; To obtain the better mixing state, improve the completing combustion ratio, reduce the carbon monoxide generation, the protection environment.

For certain combustion-supporting air quantity and fuel gas supply amount are adapted, on described Gas Pipe 53, be provided with initiatively intake valve 51, and with described blast pipe 33 on the driven air intake valve 32 that is provided be coordinated type and be connected.After adjusting manual gas valve 52, initiatively form certain adjusting ratio between intake valve 51 and the driven air intake valve 32; When needing to strengthen firepower, drive big active intake valve 51, the fuel gas supply amount increases, and through linkage 8 driven air intake valve 32 is opened greatly thereupon simultaneously, and coming increases to the intake of blower fan 31, the combustion air abundance, and the combustion process aggravation, firepower increases naturally.Simultaneously, air intake increases through directly drawing combustion tube 21 wind-force, also makes flame rapidly near the bottom of a pan heating, promotes heat exchanging process; And reduce flame in the holdup time of burner hearth, prolong stove and accessory service life.

Described blast pipe (33) is slick and sly with the import of described burner hearth blast pipe and is connected, and the running resistance of F.D in airduct 33 reduced, and reduces the noise that the air blast link produces.Simultaneously, because this device efficiency of combustion improves, the required blow rate required reduces, and also further reduces noise, reduces the required power consumption of air blast simultaneously.
