[0004] When the range hood is in use, oil smoke condenses into oil droplets on the oil filter screen and flows along the oil filter screen to the collection box for collection. However, the oil droplets with lower temperature tend to solidify on the oil filter screen after being attached to dust. After long-term use, the oil droplets will fall onto the countertop, which is inconvenient for users. In addition, the oil stains accumulated over a long period of time tend to clog the mesh holes on the oil filter screen, affecting the subsequent use of the range hood. Therefore, the oil filter screen of the range hood needs to be cleaned. The existing cleaning method is usually to remove the oil filter screen for cleaning or to spray cleaning fluid for cleaning. The former is inconvenient to disassemble and easily damage parts during cleaning, and the latter has a general cleaning effect, and there are still some stubborn oil stains that cannot be handled.

The moving frame 41 is threadedly connected to the bidirectional screw rod 62. The second motor 61 drives the bidirectional screw rod 62 to rotate and drive the moving frame 41 to reciprocate, and drives the brush roller 42 to reciprocate, so as to repeatedly brush the two sides of the oil filter mesh plate 3.

[0046] Reference Figure 5 and Figure 7 A cleaning liquid storage tank 18 is arranged at the top of the shell 1, and a connecting pipe 19 is arranged on one side of the cleaning liquid storage tank 18. One end of the connecting pipe 19 penetrates into the shell 1 and is connected to the movable frame 41. The connecting pipe 19 is a hose. A liquid outlet groove 421 is arranged in the brush roller 42. The connecting pipe 19 is connected with the brush roller 42 at the liquid outlet groove 421. A plurality of penetrating liquid outlet holes 422 are arranged on the circumferential side wall of the brush roller 42. The liquid outlet holes 422 are connected with the liquid outlet groove 421. The cleaning liquid in the cleaning liquid storage tank 18 is transported to the liquid outlet groove 421 on the inner side of the brush roller 42 through the connecting pipe 19. When the brush roller 42 rotates, the cleaning liquid flows out from the liquid outlet hole 422 of the brush roller 42 and falls on the oil filter mesh plate 3. The bristles on the brush roller 42 brush the oil filter mesh plate 3, and the cleaning effect is better.

[0047] Reference Figure 1 A valve 191 is disposed on the connecting pipe 19. The valve 191 is used to control the amount of cleaning liquid discharged from the connecting pipe 19 according to actual conditions, thereby reducing the waste of cleaning liquid.

[0048] Reference Figure 8 A closing mechanism 7 is provided on the upper side of the oil groove 17, and the closing mechanism 7 includes a closing plate 71 and a cylinder 72. A guide plate 73 is obliquely provided on the housing 1 at the upper side of the oil groove 17. The guide plate 73 is distributed along the length direction of the oil groove 17. The cylinder 72 is provided on the guide plate 73, and the closing plate 71 is slidably installed on the guide plate 73.

The closing plate 71 is connected to one end of the piston rod of the cylinder 72, and the housing 1 is provided with a guide pipe 74 on one side of the closing plate 71. When the range hood is in normal use, the sealing plate 71 is opened and located at the guide plate 73, and the guide pipe 74 is closed. At this time, the oil drops to the oil tank 17 for collection; when the oil filter screen plate 3 needs to be cleaned, the cylinder 72 drives the sealing plate 71 to slide to close the oil tank 17, and the guide pipe 74 is opened. At this time, the cleaning liquid is on the upper side of the sealing plate 71 and the guide plate 73, flows along the guide plate 73 and the sealing plate 71, and is discharged from the shell 1 through the guide pipe 74 on one side, so as to separate the cleaning liquid and the recovered oil.

[0049] The implementation principle of a range hood with an oil removal device in an embodiment of the present application is as follows: during normal operation, the first motor 21 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the baffle 14 to rotate and open. At the same time, the rotating shaft 13 drives the oil filter screen 3 to rotate to one side of the enclosure frame through the first connecting rod 51 and the second connecting rod 52. At this time, the filter plate 32 blocks the air inlet 12 to perform the range fumes extraction operation.

[0050] When not in operation, the first motor 21 drives the rotating shaft 13 to drive the baffle 14 to rotate and close. At this time, the oil filter screen plate 3 rotates to a vertical state, and the oil droplets on the oil filter screen plate 3 flow along the plate body to the oil tank 17 for collection due to gravity.

[0051] When cleaning is required, the cylinder 72 drives the sealing plate 71 to close the oil tank 17. At the same time, the cleaning liquid storage tank 18 transports the cleaning liquid to the brush roller 42 through the connecting pipe 19. The second motor 61 drives the movable frame 41 to move, driving the brush roller 42 to rotate to repeatedly brush the two sides of the oil filter screen plate 3. The cleaning liquid is discharged from the shell 1 through the guide pipe 74 on one side.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
