Abstract
The utility model relates to a domestic fume air curtain blocking collecting ejection type efficient low-noise fume exhauster without disassembly and wash, belonging to the class of kitchen tools. The utility model comprises a fan (1) fixed on an outdoor wall support (7) and an air jet pipe (3) communicated with an air outlet of the fan and an ejection pipe (4), and the wind rate is allocated by an adjusting valve (2). The indoor part of the air jet part (3) surrounds a cooking stove, and the periphery of the upper part of the air jet pipe (3) is provided with a plurality of air jet holes (A), and a plurality of air jet micropores (B) are arranged at the inner lower side of the air jet pipe (3). The ejection pipe (4) is inserted into an inner cavity of a fume exhaust pipe (6), a fume collecting hood (5) is arranged above the cooking stove, and the upper part of the fume collecting hood (5) is communicated with the fume exhaust pipe (6). When the utility model works, the air curtain is formed and the fume diffusion is blocked. The fume exhaust uses the ejection type, and the utility model has the advantages of high fume collecting rate, low noise, long service life, disassembly and cleaning free, complete combustion, little production of harmful gas, small pollution of kitchens, etc. and is an ideal tool replacing the existing domestic fume exhausters.
Description
Affiliated field
The utility model relates to a kind of kitchen utensils that family uses that are suitable for, and specifically is that a kind of family expenses air curtain obstruct collecting jet type high-efficient low-noise exempts to unpick and wash kitchen hood.
Background technology
At present, the family expenses kitchen hood still generally adopts the direct suction-discharge type of blower fan.Part contains the flue gas body and is inhaled into the impeller middle part, discharges under centrifugal action.This mode is mainly leaned on the suction force of blower fan, but this suction force only acts on obviously near air entry and decaying rapidly along with distance increases, and the efficient of historical facts or anecdotes border fume exhaust is lower, and service time, long-acting more rate was low more, simultaneously, it is very big influenced by indoor air flows.In addition, contain the flue gas body and directly enter body, through impeller, make that greasy dirt accumulates in impeller and the casing, dry up, fouling, clean very difficult.This not only makes the machine internal contamination serious, has also destroyed the dynamic balancing of impeller, and vibration and operation noise increase, and have a strong impact on result of use, reduction of service life.Become the existing fatal technological deficiency of family expenses kitchen hood.
Summary of the invention
The purpose of this utility model provides a kind of family expenses air curtain obstruct collecting jet type high-efficient low-noise and exempts to unpick and wash kitchen hood.It not only has the isolating oil soot diffusion and wraps up in the function that the volume oil smoke imports exhaust fume collecting hood, and outdoor owing to blower fan is placed, and fume exhaust adopts injection type, and oil smoke does not enter blower fan, so noise reduces, no greasy dirt in the blower fan need not unpicked and not washed, and smoke exhaust efficiency significantly improves.
The purpose of this utility model is achieved through the following technical solutions, by blower fan, and control valve, air jet pipe, induction tunnel, exhaust fume collecting hood, smoke exhaust pipe, fan supporter is formed.Described blower fan is installed on the outdoor support, and its exhaust outlet is communicated with air jet pipe and induction tunnel.In the air jet pipe inlet chamber, and be looped around around the kitchen range, offer many puff prots at a certain distance around the part top periphery around the kitchen range, inner underside is offered some jet micropores; Induction tunnel is inserted into the smoke exhaust pipe inner chamber.Described exhaust fume collecting hood is installed in the top of kitchen range, and its top is communicated with smoke exhaust pipe, and smoke exhaust pipe passes wall to outdoor; Control valve is installed in the induction tunnel, regulates and distributes the air quantity of induction tunnel and air jet pipe.
The part that described air jet pipe is looped around around the kitchen range can be installed separately, also can be fabricated to one with kitchen range.The puff prot of offering on it, jet micropore can be flat rectangles, circular or other shape.
The utility model advantage compared with prior art is to have taked following technical measures: (1) blower fan is installed in outdoor, and its exhaust outlet is communicated with air jet pipe and induction tunnel.(2) in the air jet pipe inlet chamber, and be looped around around the kitchen range, be looped around kitchen range its top periphery of part on every side and offer many puff prots at a certain distance, inner underside is offered jet micropore.(3) induction tunnel is inserted into the smoke exhaust pipe inner chamber.(4) exhaust fume collecting hood is for partly putting the single thin layer shell structure.Owing to taked these technical measures, make the utility model that following good effect be arranged: (1) blower fan is installed in outdoor, indoorly is not subjected to its noise effect.(2) but the jet formed air curtain isolating oil soot diffusion of many puff prots of offering by the air jet pipe periphery that is looped around around the kitchen range and wrap up in the volume oil smoke from bottom to top and import in the exhaust fume collecting hood, improve smoke collecting efficiency.The outdoor oxygen air that is rich in by the some jet micropore ejections of air jet pipe inner underside can make burning more abundant, and fuel savings reduces pernicious gas and produces.(3) fume exhaust adopts injection type, and oil smoke is without blower fan, and no greasy dirt, impeller remain cleaning in the blower fan, and its dynamic balancing keeps for a long time, vibrate little, noise is low, the life-span is long.Therefore, the advantage that the utlity model has the smoke collecting efficiency height, noise is low, the life-span is long, exempt to unpick and wash, sufficient combustion, and pernicious gas produces few, and kitchen pollution is little etc.And cheap, be convenient to implement, be easy to promote.
Description of drawings
Fig. 1 is that the utility model family expenses air curtain intercepts the main TV structure schematic diagram that the collecting jet type high-efficient low-noise exempts to unpick and wash kitchen hood.Dotted line is an outdoor section.
Fig. 2 is the A-A sectional structure schematic diagram of main TV structure schematic diagram.
Embodiment
The utility model concrete structure embodiment is described in conjunction with the accompanying drawings: blower fan 1 as shown in Figure 1 and Figure 2 is fixed on the outdoor wall support 7, its exhaust outlet is communicated with air jet pipe 3 and induction tunnel 4 respectively, and regulate and distribute air quantity by control valve 2, be looped around around the kitchen range after in the air jet pipe inlet chamber, top such as Fig. 1, Fig. 2 A show that periphery offers many puff prots at a certain distance, and inner underside is offered some jet micropores shown in Fig. 1, Fig. 2 B; Induction tunnel 4 draws the inner chamber that is inserted into smoke exhaust pipe 6 on the blower fan exhaust outlet; Smoke exhaust pipe 6 indoor end connected set petticoat pipes 5, exhaust fume collecting hood 5 is installed in the top of kitchen range, is semi-open single thin layer shell structure.The necessary aspect of exhaust fume collecting hood and each pipeline is all done oily dirt free and is handled, and slight greasy dirt can be wiped examination at any time.
The utility model is realized by following program, start blower fan 1, the high velocity air of its discharge part after control valve 2 distributes enters air jet pipe 3, and be looped around many puff prots ejections that the part top periphery around the kitchen range is offered by it, form air curtain, but this air curtain isolating oil soot diffusion, and wrap up in from bottom to top in the volume oil smoke importing exhaust fume collecting hood 5; Another part enters the smoke exhaust pipe inner chamber by induction tunnel 4, the gas flow in the injection smoke exhaust pipe, and the oil smoke in the exhaust fume collecting hood is inhaled in the smoke exhaust pipe, discharges outdoor with injection air.The micropore of playpipe inner underside also sprays the outdoor oxygen air that is rich in, and makes burning more abundant.
