Abstract
The utility model relates to a kitchen appliance. The utility model is characterized in that an air flow exhaust port (4) used for forming an air curtain is provided with an air guide channel (3), the airflow (6) generated by an air curtain fan is guided to flow out downwards through the air guide channel (3), and a dense air curtain with good directivity is formed. The utility model overcomes the defect that the air curtain generated by the similar kitchen ventilator is in an outward dispersing shape, and the effective distance is short. The utility model has the advantages that the cooking fume can be effectively closed, the cooking fume can be prevented from dissipating, the fresh air can be prevented from entering into the air suction low pressure zone, the operating distance is far, the cooking fume exhaust effect is favorable, and the efficiency is high.
Description
The utility model relates to kitchen electric equipment, particularly relates to a kind of smoke exhaust ventilator that can produce air curtain.
Existing smoke exhaust ventilator has a kind of smoke exhaust ventilator that can produce air curtain in (claiming to take off lampblack absorber, smoke exhaust, range hood, range hood again), the gas outlet that can produce air curtain is arranged on its lower cover, air curtain motor and fan blade are housed on the upper cover plate, its purpose of design is to allow air curtain that oil smoke is blocked in order to avoid oil smoke is escaped, though make smoke exhaust ventilator do thinlyyer or adorn higher also normal smoke pumping.But its weak point is that the downward air channel of air curtain air flow outlet is too short, only is the lower cover thickness of slab of smoke exhaust ventilator (it is thick to be generally 1～2mm).Because downward air channel is too short, does not have guide effect, the air curtain of its generation is not vertically downward but outwards scatters; The air curtain air-flow is not concentrated yet in addition, and EFFECTIVE RANGE is short, does not really perform to role that air curtain is answered.And that the shortcoming of other smoke exhaust ventilator is a fuselage is thick, materials are many, mounting distance is near, and other non-oil smoke composition is many in the gas of being taken away, and operating efficiency is not high.
The purpose of this utility model provides real downward air curtain of a kind of energy generation and the smoke exhaust ventilator that the air curtain air-flow is concentrated, EFFECTIVE RANGE is far away.
The purpose of this utility model realizes by following design: the air curtain air flow outlet at smoke exhaust ventilator is provided with the guiding air channel.The height in guiding air channel is generally greater than the width of air stream outlet, highly preferably 1.5～3.5 of width times.Like this air curtain electric fan produce airflow passes guiding air channel the time with the wind the Dow Jones index forms downward remote air curtain and surrounds oil smoke to outflow, prevent that oil smoke escape and outside air from entering the low-pressure area of bleeding, and brings into play its due effect.
The utility model is compared with the existing similar smoke exhaust ventilator that can produce air curtain, because the air curtain air-flow concentrates downwards, seals therefore that oil smoke is effective, distance, smoke pumping efficient height.It can install higherly under the same conditions, and perhaps the power of required air curtain motor can be smaller under identical height.And compare with other smoke exhaust ventilator, it can close oil smoke, and can effectively reduce the other cleaned air of air inlet and enter smoke exhaust ventilator, so the smoke pumping distance is farther, and efficient is also higher, can significantly reduce the non-oil smoke amount of suction.Because of its smoke pumping distance,, can make the operating space in kitchen seem bigger like this so can install higherly.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the elevational schematic view of an embodiment of the utility model.
Fig. 2 is the front elevational schematic of Fig. 1 embodiment.
Fig. 3, the 4th, the partial enlarged drawing in the air channel of partly leading among this embodiment.
The smoke exhaust ventilator that can produce air curtain described in the utility model is provided with air curtain air flow guide baffle 1,2, forms guiding air channel 3 between the deflector apron 1,2.After entering guiding air channel 3, the air-flow 6 that is produced by the air curtain electric fan is directed downward diffluence (shown in the solid arrow among Fig. 3), if and the air channel 3 of not leading, outwards flow away (shown in the dotted arrow among Fig. 3) of will taking advantage of a situation when air-flow 6 flows out naturally is difficult to form decent air curtain.
The height h in guiding air channel is designed to 1.5 times of air stream outlet width b in the present embodiment.Deflector apron 1,2 can be directly connected on the lower cover 5 of smoke exhaust ventilator, but also connects (as shown in Figure 4) with lower cover 5 again after the bending; Deflector apron also can be made in machine chamber the inside, or forms after lower cover or preceding, the left/right panel bending; Deflector apron 1,2 both can be vertically downward, also can outward-dippingly perhaps draw close mutually below two baffle plates 1,2 to strengthen the scope of sealing oil smoke, make below the guiding air channel narrower than top, to increase the speed that air-flow flows out.For attractive in appearance, deflector apron 1,2 can select for use transparent plastic to make in addition.
Claims (2)
1, a kind of smoke exhaust ventilator that can produce air curtain is characterized in that: there is guiding air channel (3) in the exit (4) at smoke exhaust ventilator air curtain air-flow.
2, the described smoke exhaust ventilator of claim 1 is characterized in that: the height h in guiding air channel (3) is 1.5～3.5 times of air stream outlet width b.
