Novel range hood

Abstract

The utility model provides a novel range hood which comprises an exhaust fan, a box body and an exhaust fume collecting hood, an air deflector and an inclined lining plate are arranged in the exhaust fume collecting hood, the inclined direction of the lining plate extends upwards from the edge of the exhaust fume collecting hood, the air deflector is positioned in the center of the bottom of the exhaust fume collecting hood, and an air inlet is formed between the air deflector and the lining plate. Due to the fact that the inner lining plate is the inclined plate extending from bottom to top, when the exhaust fan works, the negative pressure area below the exhaust fume collecting hood can be transversely enlarged towards the periphery, and therefore the size capable of being sucked below the exhaust fume collecting hood is increased, and oil fume is effectively prevented from escaping.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of range hood. BACKGROUND

[0002] The existing range hood has various shapes, but is mainly composed of a smoke collecting cover, an air extractor and a box body. Most of the air extraction openings of the smoke collecting cover are arranged at the edge of the smoke collecting cover, such as the front edge, and some air extraction openings are arranged at the middle part of the smoke collecting cover. However, the above-mentioned range hoods have the problem of poor smoke collection effect and oil fume escape. SUMMARY

[0003] In view of the above-mentioned problems of the prior art, the utility model aims to provide a range hood which can effectively prevent oil fume escape and has good oil fume suction effect.

[0004] The utility model realizes the above-mentioned purpose in the following way:

[0005] A novel range hood comprises an air extractor, a box body and a smoke collecting cover, wherein the smoke collecting cover is internally provided with a wind deflector and an inclined inner lining plate, the inner lining plate is inclined in a direction extending upward from the edge of the smoke collecting cover, the wind deflector is arranged at the center of the bottom of the smoke collecting cover, and an air inlet is formed between the wind deflector and the inner lining plate.

[0006] The wind deflector is internally provided with an air inlet groove.

[0007] The air inlet groove is in the shape of a funnel with the air inlet being larger than the air outlet.

[0008] The wind deflector is hingedly connected to the inner lining plate through a downwardly extending connecting piece, and is connected to the inner lining plate through a magnet on the other side of the hinged connection.

[0009] The magnet is arranged at the front end of the machine body, is fixed to the lower end of a vertical column, and the vertical column is fixed to the inner lining plate.

[0010] The inner lining plate is divided into a front side plate and left and right side plates, and is internally provided with upwardly turned edges, and the connecting piece and the vertical column are respectively fixed to the turned edges of the left and right side plates and the turned edge of the front side plate.

[0011] The front of the smoke collecting cover is provided with a switch mounting area, a shape maintenance window is arranged at the back of the switch, and the window is closed by a sheet connected to the smoke collecting cover through screws.

[0012] The utility model has the advantages that the air inlet is formed between the wind deflector and the inner lining plate, and the inner lining plate is an inclined plate extending upward from the bottom. When the air extractor is working, the negative pressure area below the smoke collecting cover will expand horizontally to the periphery, thereby increasing the volume that can be sucked below the smoke collecting cover and effectively preventing oil fume escape.

[0018] Referring to Figures 1 to 4 A novel range hood, comprising a suction fan, a box body 1 and a smoke collecting cover 2, the smoke collecting cover 2 is internally provided with an air deflector 3 and an inclined inner lining plate 4, the direction of the inclination of the inner lining plate 4 is upwardly extending from the edge of the smoke collecting cover 2, the air deflector 3 is located at the center of the bottom of the smoke collecting cover 2, and an air inlet 5 is formed between the air deflector 3 and the inner lining plate 4. Since the inner lining plate 4 is an inclined plate extending from bottom to top, when the suction fan is working, the negative pressure area below the smoke collecting cover 2 will expand horizontally to the periphery, thereby increasing the volume that can be sucked below the smoke collecting cover 2, and effectively preventing the escape of oil fume.

[0019] In order to further improve the suction capacity of oil fume and prevent the escape of oil fume, the air deflector 3 is provided with an air inlet groove 6 in the middle.

[0020] The air inlet groove 6 is in the form of three funnels, and the air inlet is larger than the air outlet, so as to increase the suction capacity of the air inlet groove 6.

[0021] In addition, the air deflector 3 is hingedly connected to the inner lining plate 4 through a downwardly extending connecting piece 7, and the air deflector 3 is connected to the inner lining plate 4 through a magnet 8 relative to the other side of the hinged connection. The air deflector 3 can be opened by pulling it downwardly and overcoming the suction force of the magnet 8, so as to facilitate the cleaning of the oil cup 14 inside the machine body; the air deflector 3 and the magnet 8 can be reconnected by allowing the magnet 8 to attract the air deflector 3, so as to facilitate use.

[0022] In order to further facilitate the opening or covering of the air deflector 3, the magnet 8 is located at the front end of the machine body, the magnet 8 is fixed to the lower end of a vertical column 9, and the vertical column 9 is fixed to the inner lining plate 4.

[0023] Moreover, the inner lining plate 4 is divided into front and side plates, and the inner side is provided with upward turned edges 10, and the connecting pieces 7 and the upright columns 9 are fixed to the turned edges 10 of the side plates and the turned edges 10 of the front plate respectively. The components such as the connecting pieces and the upright columns can be installed or dismounted by opening the air baffle 3, and the installation and maintenance are convenient. Moreover, the inclined front and side plates form a gradually enlarged negative pressure area from top to bottom under the fume hood, and the oil fume is prevented from escaping.

[0024] In order to further facilitate the use or maintenance of people, the front of the fume hood 2 is the installation area of the switch 11, the switch maintenance window 12 is arranged behind the switch, and the sheet 13 is connected with the fume hood 2 by screws to close the window 12.
