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, which comprises a shell, a filter screen and a driving part. The filter screen is made of flexible flame-retardant paper. The edges are rolled into a web structure that is gradually stacked from the inside to the outside, the axial length of the web structure matches the width of the air inlet, and the axial direction of the web structure is along the first width edge of the air inlet Extending, the free end of the paper roll structure extends to the second width edge of the air inlet so as to form a filter screen covering the air inlet, the driver is arranged at the second width edge of the air inlet of the housing and is used to place the flexible flame-retardant paper Winding recycling. The invention can adjust the total area of ​​filter holes by pulling the flexible flame-retardant paper, so as to realize the adjustment of the air inlet area of ​​the air inlet according to the concentration of oil fume; at the same time, the flexible flame-retardant paper after a period of use can be recycled by rolling and can be replaced with new ones. filter to keep the filter clean and improve the filtering effect.

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...
