Abstract

The utility model provides a smoke exhaust ventilator for kitchen, and particularly discloses an integral air curtain smoke exhaust ventilator which comprises a smoke exhaust ventilator. An air curtain chamber is arranged behind the smoke exhaust ventilator; a blowing fan is installed in the air curtain chamber; the air outlet of the blowing fan are communicated with an air outlet pipe arranged on a hearth through blast pipes on the left and right sides of the air outlet; an exhaust vent is arranged on the air outlet pipe; and the air outlet pipe adopts a U-shaped pipe and is arranged on the hearth. The smoke exhaust ventilator is provided with two sets of mechanisms, one set of the mechanism is that air produced by the blowing fan in the air curtain chamber is blown out off the exhaust vent on the air outlet pipe through the blast pipes and the air outlet pipe, the air blown from the lower side to the upper side forms an air curtain, not only the escaping of oil smoke is stopped, but also the oil smoke can be guided to directly flow upward, and further the air curtain is convenient for the smoke exhaust ventilator to sufficiently exhaust the oil smoke from the upper part; and the other set of the mechanism is that an exhaust fan of the smoke exhaust ventilator exhausts the oil smoke upward, to ensure that the whole system can sufficiently exhaust the oil smoke with a fan with low power, and harms of the oil smoke in the kitchen is reduced.

Description

Integral type air curtain smoke exhaust ventilator

Technical field

The utility model relates to a kind of culinary smoke exhaust ventilator, is specifically related to a kind of integral type air curtain smoke exhaust ventilator.

Background technology

The oil smoke that the kitchen cooking is produced contains multiple pernicious gas, is greatly injuring people's physical and mental health; And, will in the kitchen, produce a lot of oil stains within the general several months because oil smoke can not directly be discharged to outdoorly, and to clean very difficultly, the secondary pollution that causes is also threatening kinsfolk's health always.

In order to solve this difficult problem, many air curtain smoke exhaust ventilators have appearred at present, be to intercept cross-ventilated aerology principle according to air curtain, air curtain is set around gas-cooker, oil smoke is confined in the confined space that air curtain surrounds, utilize the top smoke exhaust ventilator to absorb again, this smoke exhaust ventilator has improved the absorption efficiency of lampblack absorber widely, has reduced the harm of kitchen fume.Patent CN2009201401849 has announced a kind of range hood that utilizes the air curtain generating means to prevent the oil smoke flight, comprise lampblack absorber main air blower assembly, smoke collecting chamber and cover plate, the air curtain generating means is arranged between smoke collecting chamber and the cover plate, be distributed on lampblack absorber smoke collecting chamber circumferential perimeter, wherein, the air curtain generating means comprises axial fan, has air inlet above the air curtain generating means, and the bottom is connected with long and narrow air outlet.The deficiency of such lampblack absorber is: ⑴ air curtain air outlet blows to the flare of cooking stove easily on cooking stove top during air-out, and heat is scattered and disappeared; ⑵ air curtain air outlet dispels the part oil smoke during air-out easily on cooking stove top; ⑶ inner small machine is many, complex circuit, and oil stain increases with the passage of time, loose contact easily.

Summary of the invention

The utility model has overcome the deficiencies in the prior art, and a kind of integral type air curtain smoke exhaust ventilator is provided, and it is simple in structure, convenient disassembly, cost is low, and noise is little, not only overcome existing air curtain generating means instability, easily dispelled the shortcoming of oil smoke, and can guarantee that oil smoke is absorbed more thorough.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of integral type air curtain smoke exhaust ventilator, comprise smoke exhaust ventilator, wherein: be provided with the air curtain cabin in the back of smoke exhaust ventilator, in the air curtain cabin pressure fan be housed, the ajutage of the air outlet of pressure fan by the left and right sides be arranged on the kitchen range top on discharge pipe communicate, be provided with exhaust vent above the discharge pipe.

Further, described discharge pipe is shaped as the U-shaped pipeline.

The beneficial effects of the utility model are:

1, the utility model is to be provided with the air curtain cabin in the back of smoke exhaust ventilator, in the air curtain cabin pressure fan is housed; Ajutage is equipped with in the left and right sides at the air outlet place of pressure fan; Ajutage and the discharge pipe that is contained on the kitchen range top communicate, and are contained in that discharge pipe is lower than cooking stove on the kitchen range top, and the wind that the exhaust vent that is provided with above discharge pipe blows out can not blow to the flare of cooking stove and heat is scattered and disappeared;

2, discharge pipe of the present utility model be shaped as the U-shaped pipeline, and be arranged on the kitchen range top; The wind that pressure fan in the air curtain cabin blows out is by ajutage, discharge pipe, blow out by the exhaust vent above the ajutage again, form air curtain, not only stoped the oil smoke escape from the following wind that upwards blows, and bootable oil smoke is directly upwards mobile, is more conducive to lampblack absorber and fully takes oil smoke from top away;

3, the utility model is provided with two-way mechanism, and one the tunnel is that pressure fan by the air curtain cabin forms air curtain from following to up-draught; Another road is the smoke pumping that makes progress of the air exhauster by smoke exhaust ventilator, and whole system can fully be taken oil smoke away with the blower fan of smaller power, has reduced the harm of kitchen fume.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the ajutage of air curtain part of the present utility model and the structural representation of discharge pipe.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, 2, a kind of integral type air curtain smoke exhaust ventilator, comprise smoke exhaust ventilator 4, be provided with air curtain cabin 1 in the back of smoke exhaust ventilator 4, pressure fan 2 is housed in the air curtain cabin 1, the ajutage 3 of the air outlet of pressure fan 2 by the left and right sides be arranged on the kitchen range top on discharge pipe 6 communicate, discharge pipe 6 be shaped as the U-shaped pipeline, and be arranged on the kitchen range top, be provided with exhaust vent 7 above the discharge pipe 6.The wind that pressure fan 2 in air curtain cabin 1 blows out is by ajutage 3, discharge pipe 6, blow out by the exhaust vent 7 above the ajutage 6 again, form air curtain from the following wind that upwards blows, not only stoped the oil smoke escape, and bootable oil smoke is directly upwards mobile, is more conducive to lampblack absorber and fully takes oil smoke from top away.

Referring to Fig. 1, Fig. 2, during use, the wind that is blown out by pressure fan 2 enters the discharge pipe 6 that is placed on the kitchen range top through air outlet along the ajutage 3 of the left and right sides, and the U-shaped pipeline along discharge pipe 6 upwards blows from exhaust vent 7 again, forms air curtain; The air curtain that forms has not only stoped the oil smoke escape, also guides oil smoke directly upwards to flow, and cooperates air exhauster 5 updrafts of smoke exhaust ventilator 4 simultaneously, reaches the effect that thoroughly pumps oil smoke.

Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
