The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] The following is a reference appendix. Figures 1 to 12 A range hood according to an embodiment of the present invention is described.

[0045] like Figures 1 to 12 As shown, the range hood according to an embodiment of the present invention includes: a range hood body 1, an oil filter 2, a flap 3, and a cleaning component 4. The range hood body 1 is provided with an air inlet 11, the oil filter 2 is disposed at the air inlet 11, the flap 3 is connected to the range hood body 1, and the flap 3 is movable between a first position with the air inlet 11 open and a second position with the air inlet 11 closed. The cleaning component 4 is disposed on the side of the flap 3 adjacent to the oil filter 2, and the flap 3 can drive the cleaning component 4 to move between the first and second positions to clean the oil stains on the oil filter 2.

[0046] According to the range hood of the embodiment of the present application, the cleaning assembly 4 can be moved between the first position and the second position by the flap 3, so that the cleaning assembly 4 can be moved relative to the oil screen 2, and thus the oil stain on the oil screen 2 can be cleaned. Therefore, the range hood of the embodiment of the present application can clean the oil stain on the oil screen 2 without disassembling the oil screen 2, and only by opening and closing the air inlet 11 by the flap 3. The linkage is strong, the structure is simple, the design is reasonable, the space layout in the range hood body 1 is optimized, and the cleaning effect is good.

[0047] In some embodiments, as shown in Figure 2 , the air inlet 11 is one, and the single air inlet 11 is arranged on the front face of the range hood body 1 and extends along the length direction of the range hood body 1. By arranging the air inlet 11 as one, the range hood of the embodiment of the present application can reduce the number of parts in the range hood body 1, facilitate assembly, and has a simple structure and good practicability.

[0048] In some embodiments, as shown in Figure 1 and Figure 3 , the air inlet 11 is two, and the two air inlets 11 are arranged on the front face of the range hood body 1 and are arranged at intervals along the length direction of the range hood body 1. It can be understood that each air inlet 11 corresponds to a flap 3, and each flap 3 is provided with a cleaning assembly 4. The two flaps 3 can be controlled independently, so that the user can open one or two air inlets 11 according to actual needs, thereby facilitating the use of the user, and the oil fume extraction effect of the range hood can be improved.

[0049] In some embodiments, as shown in Figure 4 , Figure 6 and Figure 7 , the range hood further comprises a first driving component 5, the first driving component 5 is connected with the flap 3 and the range hood body 1, and the first driving component 5 is used for driving the flap 3 to rotate between the first position and the second position. The range hood of the embodiment of the present application drives the flap 3 to move by the first driving component 5, so that the air inlet 11 can be automatically opened and closed, and the oil screen 2 can be automatically cleaned, thereby improving the automation degree of the range hood, having high reliability, and being convenient for the user to use.

[0050] Optionally, as shown in Figure 4 , Figure 6 and Figure 7As shown, the first driving component 5 includes a first driving motor 51 and a connecting rod 52. The side of the flap 3 facing away from the oil filter 2 is pivotally connected to the range hood body 1. The first driving motor 51 is located inside the range hood body 1. One end of the connecting rod 52 is connected to the first driving motor 51, and the other end of the connecting rod 52 is connected to the flap 3. The first driving motor 51 drives the connecting rod 52 to move, thereby causing the flap 3 to rotate between a first position and a second position. Specifically, a support plate 13 is provided inside the range hood, and the first driving motor 51 is located on the support plate 13. The connecting rod 52 includes multiple connecting segments 521, which are pivotally connected in sequence. When the first driving motor 51 rotates, it can drive the connecting rod 52 to move, thereby pulling the flap 3 to rotate between the first position and the second position. According to the embodiment of the present invention, the range hood can drive the connecting rod 52 to move via a motor, thereby causing the flap 3 to rotate between the first position and the second position, thus simplifying the structure of the range hood and improving the linkage effect.

[0051] In other embodiments, such as Figure 5 As shown, the range hood also includes a second driving component 6, which is connected to the flap 3 and the range hood body 1, for driving the flap 3 to translate between a first position and a second position. In this embodiment of the invention, the range hood drives the flap 3 to translate between the first and second positions via the second driving component 6, thereby causing the cleaning component 4 to move and clean the grease on the oil filter 2. This simplifies the structure of the range hood and improves its linkage effect. Specifically, the second driving component 6 is one of a linear motor 61, a cylinder, and an oil cylinder. For example, the second driving component 6 is a linear motor 61, which is located on the rear side wall of the range hood body 1, with its other end connected to the flap 3. By configuring the second driving component 6 in the above-described structure, this embodiment of the invention simplifies the structure of the range hood and reduces its production cost.

[0052] In some embodiments, the cleaning component 4 may not directly contact the oil filter 2. For example, the cleaning component 4 may be a hot air blower, which is opposite to the oil filter 2 and can spray hot air to melt the oil stains on the oil filter 2. The flap 3 can move in a first position and a second position so that the hot air blower can clean different positions of the oil filter 2, thereby improving the cleaning effect of the cleaning component 4.

[0054] Optionally, as shown in Figure 4 and 6 The scraper 41 is made of elastic material. For example, the scraper 41 is made of silica gel material. The range hood of the embodiment of the present application can avoid the scraper 41 scratching the oil screen 2 by setting the scraper 41 to be made of elastic material, improve the service life of the scraper 41 and the oil screen 2, and make the cleaning effect of the oil stain better.

[0055] Optionally, as shown in Figures 8 to 10 The scraper 41 is detachably connected with the flap 3. It can be understood that the scraper 41 can be clamped with the flap 3, or the scraper 41 and the flap 3 can be fixed by screws or plug-in parts. The range hood of the embodiment of the present application can facilitate the assembly and disassembly of the scraper 41 by detachably connecting the scraper 41 with the flap 3, so that the scraper 41 can be replaced when it is damaged or aged, thereby improving the cleaning effect of the range hood and having good practicability.

[0056] In some embodiments, as shown in Figure 8 and Figure 9 The cleaning assembly 4 further comprises a fixed support 42 and a threaded part 43, the scraper 41 is arranged between the fixed support 42 and the flap 3, and the threaded part 43 passes through the fixed support 42 and the scraper 41 and is connected with the flap 3. The range hood of the embodiment of the present application can fix the scraper 41 by the threaded part 43 and the fixed support 42, so that the connection reliability of the cleaning assembly 4 is high, and the structure is simple, and the operator can easily assemble and disassemble the scraper 41. Specifically, the threaded part 43 is a plurality of threaded parts 43, and the plurality of threaded parts 43 are arranged along the length direction of the scraper 41, thereby further improving the fixing effect between the scraper 41 and the flap 3

[0057] Optionally, as shown in Figure 8 and Figure 9As shown, the flap 3 comprises a flap body 31 and a lining plate 32, the lining plate 32 is arranged at the inner side of the flap body 31, and the threaded member 43 is connected with the lining plate 32 through the fixing support 42 and the scraper 41. For example, the flap body 31 is made of glass, and the lining plate 32 is made of metal. A pull rivet nut can be installed on the lining plate 32, and a screw can be connected with the pull rivet nut through the fixing support 42 and the scraper 41, so as to complete the fixing work of the scraper 41. The range hood of the embodiment of the present application can improve the structural strength of the flap 3 by dividing the flap 3 into the flap body 31 and the lining plate 32, and facilitate the connection of the cleaning assembly 4 with the flap 3, so that the reliability of the flap 3 after installation with the cleaning assembly 4 is higher.

[0058] In other embodiments, as Figure 10 As shown, the cleaning assembly 4 further comprises a fixing seat 44, the fixing seat 44 is arranged on the flap 3, one of the fixing seat 44 and the scraper 41 is provided with a clamping groove 441, and the other is provided with a clamping convex 411, the clamping convex 411 is clamped in the clamping groove 441. For example, the fixing seat 44 is provided with the clamping groove 441, and the scraper 41 is provided with the clamping convex 411. Alternatively, the inner end of the clamping groove 441 is provided with an arc-shaped groove with a circular cross section, and the end of the clamping convex 411 away from the oil screen 2 is provided with a convex column with a circular cross section, and the convex column is matched with the arc-shaped groove. It can be understood that when the scraper 41 is installed, the clamping convex 411 can be inserted into the clamping groove 441 from the side of the fixing seat 44, and due to the arrangement of the arc-shaped groove and the convex column, the movement of the scraper 41 in the direction close to or away from the oil screen 2 can be avoided, so that the reliability of the scraper 41 when cleaning oil stains can be improved. In addition, the range hood of the embodiment of the present application facilitates the installation and disassembly of the scraper 41 by clamping the fixing seat 44 and the scraper 41, and the structure design is simple, and the processing and manufacturing difficulty is low.

[0059] In some embodiments, as Figure 10 As shown, at least one of the scraper 41 and the oil screen 2 is provided with a heating member 7. It can be understood that the heating member 7 can be arranged on the scraper 41 alone, or on the oil screen 2 alone, or on both the scraper 41 and the oil screen 2. The range hood of the embodiment of the present application provides the heating member 7 on the scraper 41 and the oil screen 2, so that the oil stains can be heated by the heating member 7 to soften the oil stains, thereby facilitating the cleaning of the oil stains on the oil screen 2 by the scraper 41, and the cleaning effect of the oil screen 2 can be better.

[0060] Alternatively, as Figure 10As shown, the heating member 7 comprises a first heating member 71, which is arranged in the scraper 41. Specifically, the heating member 7 can be arranged on the surface of the scraper 41 or in the interior of the scraper 41. For example, the first heating member 71 is a heating wire, which is arranged in the scraper 41 along the length direction of the scraper 41. The first heating member 71 is arranged at a distance from the free end of the scraper 41, so as not to affect the oil scraping effect of the scraper 41 and to heat the scraper 41, thereby improving the cleaning effect of the scraper 41 on the oil screen 2.

[0061] Optionally, the heating member 7 further comprises a second heating member (not shown), which surrounds the oil screen 2. For example, the second heating member can be a heating net or a heating wire, which covers the oil screen 2. The first heating member 71 and the second heating member can be heated simultaneously to further accelerate the dissolving speed of the oil stains on the oil screen 2, thereby improving the cleaning effect of the oil screen 2.

[0062] In some embodiments, as shown in Figure 6 The lower end of the oil screen 2 is provided with a first oil baffle 21, which extends towards the direction of the flap 3 and is bent upwards. In the second position, the first oil baffle 21 abuts against the scraper 41. It can be understood that the first oil baffle 21 is bent upwards to form a storage tank with the oil screen 2. The oil screen 2 can collect into the storage tank due to the action of gravity, and then be collected into the oil cup by the guiding action of the storage tank, thereby avoiding the oil stains on the oil screen 2 from flowing out of the range hood body 1. In addition, the oil stains adhered to the scraper 41 can be cleaned by the first oil baffle 21 when the scraper 41 moves, thereby improving the oil stain cleaning effect of the range hood.
