Embodiment 1

[0042] This embodiment provides an air intake system of a range hood, such as Figure 1 to Figure 4 As shown, it includes: a first drive structure 3, a volute 1, a wind wheel 2, a second drive structure 6, and a filter screen.

[0043] Wherein the volute 1 has an air inlet and an air outlet, the wind wheel 2 is installed in the volute 1, and is connected with the first driving structure 3 arranged on the opposite side of the air inlet on the volute 1, the wind wheel 2 rotates under the driving of the first driving structure 3.

[0044] In order to increase the contact area between the oil fume and the filter screen, so as to filter more oil fume, in this embodiment, the filter screen is a spherical surface protruding toward the inside of the volute 1, and this arrangement is also beneficial to the The air intake of the air intake system is guided.

[0045] Such as Figure 4 As shown, the filter screen includes a filter screen support 4 and a filter screen disc 5, wherein th...

Embodiment 2

[0053] This embodiment provides a range hood, including the air intake system of the range hood provided in the above-mentioned embodiments, the range hood can increase the contact probability between the oil fume and the filter, and can filter as much oil fume as possible .

Abstract

The invention provides an air inlet system of a range hood and the range hood. The air inlet system comprises a volute, an air wheel and a filter screen, wherein the volute is provided with an air inlet and an air outlet, the air wheel is arranged in the volute, and is connected with a first driving structure arranged at the position, on the side opposite of the air inlet, on the volute, the air wheel does rotating movement under driving of the first driving structure, the filter screen is arranged at the air inlet of the volute, is connected with a second driving structure arranged at the position of the air inlet, and can do rotating movement under driving of the second driving structure, wherein the rotating speed of the filter screen is larger than the rotating speed of the wind wheel.The filter screen and the wind wheel are driven to rotate through the different driving structures, and the rotating speed of the filter screen is larger than the rotating speed of the wind wheel sothat the contact probability between oil smoke and the filter screen can be increased, and more oil smoke can be filtered as much as possible.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an air intake system of the range hood and the range hood. Background technique [0002] As an indispensable household appliance in the kitchen, range hoods have made outstanding contributions to creating a clean kitchen environment. At present, most of the range hoods on the market use porous oil nets to filter and intercept the oil fume. After a long time, oil particles will adhere to the motor and impeller, which will increase the motor load and reduce the speed, which not only reduces the suction of the range hood and affects the life of the whole machine, but also increases the outdoor environmental pollution. . [0003] In the prior art, a dynamic filter is installed at the air inlet of the range hood, and the rotary motion of the dynamic filter is used to mechanically collide with large oil droplets and oil particles, thereby being blocked and trapped; Under the act...
