Problems solved by technology

However, when the current range hood filters the oil fume, since the filter screen is fixed, the oil fume passes through the filter screen at a large inclination angle, and the contact probability between the filter screen and the oil is relatively limited, so the ability to capture the oil is limited , the filtering effect is limited; moreover, after the filter screen of the traditional range hood captures the oil, the oil is easy to adhere to the filter screen after condensation, which not only blocks the filter screen, reduces the suction efficiency of the range hood, but also increases the frequency of cleaning the filter screen

Embodiment 2

[0016] Such as image 3 As shown, for the second embodiment of the high-efficiency range hood, the difference from the first embodiment is that: the filter screen 3 is also circumferentially evenly distributed with protrusions extending from the center of the filter screen 3 to the outer edge of the filter screen 3 The separator strips 33 on the upper and lower surfaces of the filter screen 3 are used to suppress the circumferential movement of the oil on the surface of the filter screen 3 and make the oil move radially outward as much as possible.

[0017] In addition, the inside of the follow-up shaft 32 also has an axial hole 34, and the axial hole 34 extends to the lower end surface of the follow-up shaft 32; while the upper end of the axial hole 34 only extends below the bracket 21, and Connect with the blowpipe 35 that is evenly distributed around the rotating shaft 32; the axis of the blowpipe 35 intersects with the outer edge of the filter screen 3; thus, during the ro...

Abstract

The invention provides a high-efficiency range hood. The high-efficiency range hood comprises a draught fan, an exhaust fume collecting hood, an air duct, a filter screen and an oil cup. The upper portion of the exhaust fume collecting hood is connected with the air duct. The draught fan is arranged on the upper portion of the interior of the air duct. A support is arranged below the draught fan.The support is provided with a follow-up rotary shaft of which the axis coincides with the axis of the air duct is arranged on the support. The upper end of the follow-up rotary shaft is connected with follow-up rotation fan blades. The lower end of the follow-up rotary shaft is connected with the filter screen. The filter screen is shaped like a horn with a downward opening. The circular lower edge of the filter screen is connected to the middle portion of a bearing inner ring of an annular bearing arranged on the inner wall of the air duct. The oil cup is shaped like a circular groove. The outer wall of the oil cup is inserted into the bearing inner ring. The filter capacity of the filter screen of the high-efficiency range hood is remarkably enhanced, and the filter screen cleaning frequency can be reduced.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. With the improvement of people's living standards, it has become an indispensable daily necessities for every family. The air is intercepted on the surface of the filter screen, and the air is exhausted to the outside through the range hood. However, when the current range hood filters the oil fume, since the filter screen is fixed, the oil fume passes through the filter screen at a large inclination angle, and the contact probability between the filter screen and the oil is relatively limited, so the ability to capture the oil liquid is limited , the filtering effect is limited; and, after the filter screen of the traditional range hood captures the oil, the oil is easy to adhere to the filter screen after condensation, which not only blocks the filter scree...
