Problems solved by technology

However, since the airflow of the air curtain blows from top to bottom, which is opposite to the direction of extracting oil fume, the rising oil fume will be blown down by the airflow of the air curtain near the air curtain, which will affect the effect of extracting oil fume
At the same time, the blown airflow is also easy to blow to the operator's head

Embodiment Construction

[0016] In the embodiment shown in the figure, FIG. 1 shows that an air curtain fan air inlet 2 is opened on the housing of the range hood hood 1 , and air curtain nozzles 3 are provided on the left and right sides of the front, lower, and left sides of the hood 1 . FIG. 2 shows the sides of the hood 1 and the air curtain nozzles 3 and the side windscreens 4 below the front.

[0017] As shown in Figure 3, when the air curtain fan 5 is started, the generated wind is blown into the air curtain nozzles 3 on the left and right sides of the lower front of the hood through the air channel 6, and blows along the slit-shaped air outlets of the nozzles on the left and right sides. 7 is blown out along the direction shown by arrow 9, forms air curtain.

[0018] In the II-II sectional schematic diagram shown in Fig. 4, the air curtain formed by the wind blown out by the slit-shaped air outlet 7 of the side windshield panel 4 and the air curtain nozzle 3 along the arrow 9 and the wall 8 on...

Abstract

The invention relates to an oil-smoke drawing machine for cooking by air-curtain sheltering from oil and smoke. Air-curtain fan is assembled in shell of oil-smoke drawing machine, the wind generated by fan blows out in transverse direction through backswept nozzles on the left-right side of the lower at frontal face of machine cover and air-curtain is formed; and larger smoke-collecting cover is formed with the air-curtain, side wind board on the two lower sides of upper machine cover and back wall, and can accommodate more oil-smoke which is not taken out in time. Air-curtain is like as a transparent wind board. The height between collecting smoke cover and hearth surface is decreased in the pumping oil-smoke device. The distance is decreased from 0.75m to 0.45m so the distance that oil-smoke arises into collecting cavity is shortened. When pumping oil-smoke fan starts, a larger negative pressure region is formed under the collecting cover; when outer air is compensated to collecting cover, air inlet is formed under the collecting cover and makes arising oil-smoke flows into collecting cavity as outer wind, which prevents overflow of oil-smoke and improve the pump-cleaning ratio for oil-smoke.

Description

technical field [0001] The invention relates to a cooker fume discharge device, in particular to a range hood which uses an air curtain to shield the fumes. Background technique [0002] At present, commercially available range hoods are generally divided into shallow cover type and deep cover type according to the volume of the smoke collecting hood, which are mainly composed of a machine cover, an exhaust fume blower fan, a circuit system and a smoke exhaust pipe. Because the shallow hood type range hood is too shallow, the oil fume that is too late to be sucked is easy to overflow and spread, and the effect of exhausting oil fume is poor. The deep-hood type range hood is equipped with a fume collection hood with a slightly larger volume. When the range hood fan rotates at high speed, a certain negative pressure area is formed above the fume collection hood, which can accommodate part of the fume that is too late to be sucked away. Good shape. However, during the cooking...
