Embodiment 1

[0035] The filter assembly 3 that present embodiment provides, as Figure 1 to Figure 6 As shown, it includes a filter screen 32 and a friction release mechanism; the filter screen 32 is sleeved on the friction release mechanism; the friction release mechanism is used to be sleeved on the output shaft of the motor; the output shaft speed of the motor is lower than that of the filter screen 32 When the rotating speed is set, the outer surface of the friction tripping mechanism is in pressure contact with the inner surface of the filter screen 32; skidding.

[0036] When the rotation speed of the output shaft of the motor is lower than the preset rotation speed of the filter screen 32, the outer surface of the friction release mechanism is pressed into contact with the inner surface of the filter screen 32, and the torque of the friction release mechanism is transmitted to the filter screen 32 through friction force, so that the filter The net 32 ​​and the output shaft of the m...

Embodiment 2

[0055] The air duct provided in this embodiment includes a motor 5 and the filter assembly 3 provided in Embodiment 1.

[0056] When the rotation speed of the output shaft of the motor is lower than the preset rotation speed of the filter screen 32, the outer surface of the friction release mechanism is pressed into contact with the inner surface of the filter screen 32, and the torque of the friction release mechanism is transmitted to the filter screen 32 through friction force, so that the filter The net 32 ​​and the output shaft of the motor rotate at the same speed; when the output shaft speed of the motor is greater than the preset speed of the filter screen 32, the friction force between the outer surface of the friction release mechanism and the inner surface of the filter screen 32 and the torque balance of the filter screen 32, The outer surface of the friction release mechanism and the inner surface of the filter screen 32 slip, so that the filter screen 32 maintains...

Embodiment 3

[0070] The range hood provided in this embodiment includes the filter assembly 3 provided in Embodiment 1 or the air duct provided in Embodiment 2.

[0071] When the rotation speed of the output shaft of the motor is lower than the preset rotation speed of the filter screen 32, the outer surface of the friction release mechanism is pressed into contact with the inner surface of the filter screen 32, and the torque of the friction release mechanism is transmitted to the filter screen 32 through friction force, so that the filter The net 32 ​​and the output shaft of the motor rotate at the same speed; when the output shaft speed of the motor is greater than the preset speed of the filter screen 32, the friction force between the outer surface of the friction release mechanism and the inner surface of the filter screen 32 and the torque balance of the filter screen 32, The outer surface of the friction release mechanism and the inner surface of the filter screen 32 slip, so that t...

Abstract

The invention provides a filter screen assembly, an air duct and a range hood, and relates to the technical field of kitchen appliances. The filter screen assembly comprises a filter screen and a friction tripping mechanism; the filter screen is arranged on the friction tripping mechanism in a sleeving manner; the friction tripping mechanism is used for being arranged on an output shaft of a motor in a sleeving mode; when the rotating speed of the output shaft of the motor is smaller than the preset rotating speed of the filter screen, the outer surface of the friction tripping mechanism is in compressing contact with the inner surface of the filter screen; and when the rotating speed of the output shaft of the motor is greater than the preset rotating speed of the filter screen, the outer surface of the friction tripping mechanism slips on the inner surface of the filter screen. Through the friction tripping mechanism, the preset rotating speed of the filter screen can be maintained after the filter screen reaches the preset rotating speed of the filter screen, and the rotating speed of the motor can be continuously increased, so that the motor and the filter screen can still rotate under the condition of different rotating speeds, and the noise and the wind resistance are further reduced.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a filter assembly, an air duct and a range hood. Background technique [0002] At present, when the air duct of the range hood is working, the oil fume is directly sucked into the air duct, and the oil is separated by the high-speed rotation of the impeller, and the smoke with part of the oil is discharged to the outside. After the impeller has been used for a period of time, more oil will adhere to the impeller, which will affect the life of the impeller. [0003] In order to solve the above problems, a rotating filter is installed at an air inlet of the air duct, and the rotating filter rotates synchronously with the impeller, and the oil is filtered through the rotating filter to reduce the amount of oil adhered to the impeller. [0004] However, the synchronous rotation of the rotating filter screen and the impeller may easily cause problems of large wind resistan...
