Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1~6 As shown, the range hood of this embodiment includes a housing 1, a filter screen 20 and a driving member 3. The bottom of the housing 1 has an air inlet 11, and the filter screen 20 is made of flexible flame-retardant paper. There are several filter holes 21 of different sizes, such as figure 2 As shown, the flexible flame-retardant paper is rolled around one edge to form a roll paper structure 2 that is gradually stacked from inside to outside. The axial length of the roll paper structure 2 matches the width of the air inlet 11 . The paper roll structure 2 is rotatably arranged on the casing 1 and the axial direction of the paper roll structure 2 extends along the first width edge of the air inlet 11, and the free end of the paper roll structure 2 faces the first width of the air inlet 11. The second width edge ...

Abstract

The invention relates to a range hood. The range hood comprises a shell body, a filter screen and a driving piece, the filter screen is made of flexible flame-retardant paper, a plurality of filter holes with different sizes are formed in the flexible flame-retardant paper, the flexible flame-retardant paper is wound around one edge to form a roll paper tube structure which is gradually stacked from inside to outside, the axial length of the roll paper tube structure is matched with the width of an air inlet, the axial direction of the roll paper tube structure extends along the first width edge of the air inlet, the free end of the roll paper tube structure extends towards the second width edge of the air inlet to form a filter screen which covers the air inlet, and the driving piece is arranged at the second width edge of the air inlet of the shell body and is used for winding and recycling the flexible flame-retardant paper. According to the range hood, the total area of the filterholes can be adjusted by pulling the flexible flame-retardant paper, so that the air inlet area of the air inlet is adjusted according to the lampblack concentration; meanwhile, the flexible flame-retardant paper after being used for a period of time can be replaced with a new filter screen through winding and recycling, so that the filter screen is kept clean, and the filtering effect is improved.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] When cooking, for cooking different dishes, there are often situations where sometimes the amount of oil fume is large and sometimes the amount of oil fume is small. However, the filters installed at the air inlet of most range hoods cannot adjust the air intake area according to the size of the oil fume. adjust. [0003] The Chinese patent application with the publication number CN110207202A "Cooker Hood with Adjustable Air Inlet Area and Its Control Method" discloses a structure, which includes a box body, a smoke collecting hood, an oil net structure, a fan, a sensor and a controller. The smoke hood is set under the box body, the left air inlet and the right air inlet are arranged on the smoke collecting hood, the left air inlet and the right air inlet are both equipped with an oil screen structure, the fan and the controller are all set in the box, and the sensor is set in the oi...
