Embodiment 1

[0045] This embodiment provides a filter screen for a range hood, such as figure 1 , including a mounting plate 3, a rim 2, and a plurality of blades 1 radially arranged between the mounting plate 3 and the rim 2 with the mounting plate 3 as a center.

[0046] Wherein, the mounting disc 3 is suitable for being installed on the output shaft 8 of the motor 7 , and when the motor 7 rotates, the mounting disc 3 is driven to drive the blade 1 to rotate. The rim 2 is arranged around the mounting disc 3 .

[0047]Several blades 1 are radially arranged between the mounting disk 3 and the rim 2 with the center of the mounting disk 3 as the center of the circle, the root of the blade 1 is installed on the mounting disk, and the end of the blade 1 Installed on the rim 2, and at least one blade 1 and the projection of the root of the adjacent blade 1 on the outer peripheral wall of the installation disk 3 are spaced apart in the axial direction of the installation disk 3, or the ends are...

Embodiment 2

[0057] This embodiment provides an air intake system of a range hood, such as Figure 3 to Figure 5 As shown, it includes the filter screen of the range hood provided in the above embodiment, and the motor 7 , and the mounting plate 3 is installed on the output shaft 8 of the motor 7 .

[0058] Wherein the air intake system has a volute 6 and a wind wheel 5 installed in the volute 6, the wind wheel 5 is installed on the output shaft 8 of the motor 7, and the mounting plate 3 is installed on the wind wheel 5 At the air inlet, the output shaft 8 of the motor 7 is equipped with both the wind wheel 5 and the filter screen, and the structure is simple and compact, which is convenient for users to install. Such as image 3 As shown, the mounting plate 3 is mounted on the end of the output shaft 8 of the motor 7 and fixed by a lock nut. Such as Figure 5 As shown, a safety isolation net 9 is also provided on the outside of the volute 6, which can prevent the filter from hurting th...

Embodiment 3

[0062] This embodiment provides a range hood, which includes the air intake system of the range hood provided in Embodiment 2. The range hood can filter more oil fumes and has a good air intake effect.

Abstract

The invention discloses a filter screen of the range hood. The filter screen comprises a mounting disc, a rim and a quality of blades; the mounting disc is suitable for being mounted on an output shaft of a motor; the rim is arranged around the mounting disc; and a quality of the blades are arranged between the mounting disc and the rim in a radial manner by taking the center of the mounting discas a circle center, the root part of the blade is arranged on the mounting disc, the end part of the blade is mounted on the rim, at least one blade and the projection of the root of the adjacent blade on the outer peripheral wall of the mounting disc are arranged at intervals in the axial direction of the mounting disc, or the projection of the end part on the outer peripheral wall of the mounting disc is separated from the axial direction of the mounting disc. The total area of the blades can be increased as much as possible, then the contact area between the oil fume and the filter screen is increased, therefore, the oil smoke can be filtered as much as possible, the range hood can be reduced to enter the range hood, when the motor is driven by the motor to rotate, the function of air supply and pressurization is achieved, and the oil fume suction effect can be ensured.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a filter screen of the range hood, 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 ...
