Detailed Description

The following description of the embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention.

As shown in fig. 1, an exhaust device for kitchen use, collection petticoat pipe 1 including upper and lower open-ended, collection petticoat pipe 1 upper end opening part is equipped with exhaust fan 2, and exhaust fan 2 upper end is equipped with drive arrangement 3, one side intercommunication ventilation pipe 4 of exhaust fan 2, it is convex column blend stop 5 that the cross section that is equipped with multiunit parallel to each other in the collection petticoat pipe 1, it is curved aerofoil 6 that the multiunit cross section is equipped with to correspond in the collection petticoat pipe 1 of column blend stop 5 upper end, the axle center that corresponds column blend stop 5 on the aerofoil 6 is equipped with fore-and-aft vent 7, the upper end of vent 7 is

wind chamber

8, 8 upper ends in wind chamber are exhaust fan 2. The columnar barrier strips 5 are used for differentiating the air ports and increasing the stress surfaces of the air ports, so that the air exhaust effect is improved. Specifically, the column blend stop 5 is cylindric, and the both ends of column blend stop 5 are fixed respectively or the coupling is on the inside wall of collection petticoat pipe 1. The columnar barrier strip 5 which is connected with the smoke collecting cover 1 through the shaft can rotate, so that the cleaning and sweeping are more thorough, and the sanitary environment of a canteen is improved.

In order to better define the size of the air opening and ensure the air exhaust effect, the relative sizes of all the parts are specifically defined, specifically, the closest distance between the air plate 6 and the cylindrical barrier strip 5 is 1/8-1/5 of the diameter of the cylindrical barrier strip 5, and the width of the ventilation opening 7 is the same as the closest distance between the air plate 6 and the cylindrical barrier strip 5. It is of course to be noted that the diameter of the cylindrical bar 5 should not be too large in order not to reduce the venting effect.
