Embodiment 1

[0033] Such as Figure 1 to Figure 4 As shown, the range hood according to this embodiment includes a range hood main body, an oil net 2 and an electromagnetic component 3 .

[0034] The oil screen 2 is rotatably installed on the main body of the range hood, and the electromagnetic part 3 is installed on the main body of the range hood, and can generate electromagnetic force when energized; wherein, the oil screen 2 in this embodiment can be moved in the direction of its center line of rotation , and under the electromagnetic force of the electromagnetic part 3 and / or the gravitational force of the oil net 2, it can move to the starting position that cooperates with the power device in the range hood, rotates under the drive of the power device, and moves to a position that is compatible with the oil fume The power device of the machine is disengaged, and the closed position is convenient for disassembly. Then, when the range hood in this implementation is working, the oil net...

Embodiment 2

[0043] Such as Figure 5 to Figure 7 As shown, the range hood in this embodiment includes an impeller 8 installed on the main body of the range hood. The difference from Embodiment 1 is that the electromagnetic element 3 is installed on the impeller 8, and the electromagnetic element 3 is uniformly distributed in the circumferential direction of the impeller 8. The electromagnetic block, the range hood also includes a smoke collection hood 4, and the range hood forms an activity space 7 for accommodating the oil net 2 between the smoke collection hood 4 and the electromagnetic part 3. The oil screen 2 is movably installed in the movable space 7, and when the electromagnetic part 3 is powered on, the oil screen 2 rotates with the impeller 8 driving the electromagnetic part 3 to rotate.

[0044] Specifically, when the range hood is running, the DC electromagnet block on the impeller 8 is energized to generate magnetism, so that there is a certain suction force between the oil ne...

Abstract

The invention relates to the technical field of household appliances, and in particular to a range hood. The range hood comprises a range hood main body, an oil screen rotationally mounted on the range hood main body, and an electromagnetic part which is mounted on the range hood main body and can generate electromagnetic force when being energized, wherein the oil screen can move in the rotationcentral line direction of the oil screen; under the action of the electromagnetic force of the electromagnetic part and / or the gravity of the oil screen, the oil screen is moved to a starting positionat which the oil screen is matched with a power device in the range hood and driven by the power device to rotate, and to a stopping position at which the oil screen is separated from the power device of the range hood so that dismounting is convenient; and thus, when the oil screen is cleaned, the oil screen just needs to be moved to the stopping position at which the oil screen is separated from the power device of the range hood, the oil screen is not fixed through fixing structures at the time, therefore, the oil screen can be cleaned without being dismounted, convenient and quick mounting, dismounting and cleaning of the range hood are achieved, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a range hood. Background technique [0002] At present, in order to protect the motor and separate the oil fume, the existing range hoods will install an air intake oil screen cover at the air inlet of the smoke collection hood. However, the oil screen with this structure has the following disadvantages during use: due to the high temperature oil When the drops are cold, the viscosity is very high, and a large amount of oil dirt will adhere to the oil screen when filtering the oil fume, which will reduce the oil fume separation performance of the oil screen, increase the escape probability of oil fume, and pollute the indoor and atmospheric environment. Therefore, it is necessary to regularly clean the oil screen and the like to ensure the normal performance of the range hood. However, the disassembly process of the above oil screen is relatively complicated, and it ...
