[0039] Figure 1 It is a schematic diagram of the front side of an oil fume machine in the related art; Figure 2Schematic diagram of the disassembly of the air deflector 300 of the range hood in the related art. In the related art, the air deflector 300 of the range hood is connected to the chassis 100 by screws 350 and is only supported by the chassis 100. To ensure the stability of the air deflector 300, the front and rear ends of the air deflector 300 are respectively connected to the front panel 110 of the chassis 100 and the rear panel 120 of the chassis 100 by screws 350. Mounting holes 111 are provided on both the front panel 110 and the rear panel 120 of the chassis 100 for mounting the screws 350. The screws 350 will be exposed on the surface of the chassis 100, affecting the aesthetics, especially the screws 350 on the front panel 110 of the chassis 100. However, if the screws 350 on the panel 110 are omitted, the stability of the air deflector 300 will be reduced, and there is a risk of shaking and falling off.

[0040] To improve at least one of the deficiencies in the above related art, an embodiment of the present application provides a range hood. By connecting the air deflector to the fan bracket in the chassis, the dependence of the air deflector on the chassis is reduced, so that fewer screws (even no screws) can be used to connect to the chassis, thereby improving the aesthetics.

[0041] Figure 3 Schematic diagram of one side of the front panel 110 of the range hood in the first embodiment of the present application; Figure 4 Schematic diagram of one side of the side panel 130 of the range hood in the first embodiment of the present application; Figure 5 Schematic diagram of the disassembly of the air deflector 300 in the first embodiment of the present application; Figure 6 is Figure 3 Cross-sectional view in the A direction in;

[0042] Figure 7 is Figure 4 Cross-sectional view in the B direction in. As Figures 3 to 7 shown, the range hood provided by the embodiment of the present application includes a chassis 100, and a fan assembly 200, a fan bracket 210, and an air deflector 300 disposed in the chassis 100. The chassis 100 has an air inlet 101 and an air outlet 102. The fan assembly 200 is used to provide power so that the gas (such as oil fume) outside the range hood is sucked into the interior of the chassis 100 from the air inlet 101 and then discharged from the air outlet 102 of the chassis 100. In this embodiment, the air inlet 101 and the air outlet 102 are located at both ends of the chassis 100 in the vertical direction, wherein the air inlet 101 is at the upper end of the chassis 100 and the air outlet 102 is at the lower end of the chassis 100.

[0043] The chassis 100 includes a front panel 110 and a rear panel 120 that are spaced apart in the front-rear direction. The front panel 110 is located on the front side of the chassis 100 and faces the user, while the rear panel 120 is located on the rear side of the chassis 100. Further, the chassis 100 also includes two side panels 130, which are respectively located on the left and right sides of the chassis 100. The front panel 110, the rear panel 120, and the two side panels 130 together form the cuboid chassis 100 and enclose a cuboid air duct. In other embodiments, the shape of the chassis 100 can also be cylindrical, as long as it can accommodate the fan assembly 200 and the flow guide cover 300 and achieve the function of sucking oil fumes. In this embodiment, the front-rear direction and the left-right direction of the range hood are based on the orientation of the range hood in the normal installation and use state. The range hood is usually installed above the cooking stove, and the front side of the range hood faces the user who uses the cooking stove for cooking.

[0044] In this embodiment, the fan assembly 200 is connected to the chassis 100 through a fan bracket 210. The fan bracket 210 plays a role in supporting and fixing the fan assembly 200 to ensure the stability of the operation of the fan assembly 200. Optionally, the fan bracket 210 can be connected to the chassis 100 through fasteners (such as screws and rivets), or can be connected to the chassis 100 by welding. When the fan bracket 210 is connected to the chassis 100 using fasteners, the fan bracket 210 can be connected to either the rear panel 120 or one of the side panels 130 of the chassis 100, which can avoid opening holes on the front panel 110 for mating with the fasteners to connect the fan bracket 210, thereby improving the aesthetics of the outside of the front panel 110. Of course, when the fan bracket 210 is connected to the chassis 100 by forms such as welding or bonding, it can be welded or bonded to the inner side of at least one of the front panel 110, the rear panel 120, and the side panels 130.

[0045] In this embodiment, the flow guide cover 300 is located on the side of the fan assembly 200 close to the air inlet 101 and is connected to the fan bracket 210. The flow guide cover 300 can act on the inhaled air flow to improve the turbulent impact during air flow, reduce the noise during the operation of the range hood, and enhance the user experience. In the embodiment of the present application, since the flow guide cover 300 is connected to the fan bracket 210, its stability can be guaranteed to a certain extent. Therefore, it does not overly rely on being connected to the chassis 100 through fasteners, which can reduce the number or size of fasteners on the chassis 100, thereby improving the aesthetics of the outside of the chassis 100.

[0046] Considering that the user is often facing the front panel 110 during cooking, optionally, the flow guide cover 300 is not connected to the front panel 110 by either a screw 350 or a rivet. The flow guide cover 300 can be in contact with or spaced from the inner side of the front panel 110, or can be bonded, which will not affect the aesthetics of the outside of the front panel 110.

[0047] In this embodiment, the flow guide cover 300 is connected to the back plate 120 of the chassis 100. In this way, the flow guide cover 300 is supported and fixed by the back plate 120 and the fan bracket 210, which can ensure better stability. Moreover, the back plate 120 usually does not face the user. Therefore, even if holes are opened on the back plate 120 for connection requirements to connect the flow guide cover 300, the aesthetic appearance of the range hood during use is less affected, and the negative impact on the user experience is less.

[0048] Optionally, the flow guide cover 300 is connected to the back plate 120 by at least one of screws, rivets, and snap structures, which can ensure the connection stability. Connecting the flow guide cover 300 and the back plate 120 by screws and snap structures can also facilitate the loading and unloading of the flow guide cover 300.

[0049] It should be understood that in other alternative embodiments, the flow guide cover 300 can also be only connected to the fan bracket 210 and not connected to the chassis 100, which can prevent the fasteners for fixing the flow guide cover 300 from being exposed on the surface of the chassis 100 and thus affecting the appearance of the chassis 100. In some alternative embodiments, the flow guide cover 300 can also be connected to the side plate 130 of the chassis 100. Since the side plate 130 usually does not face the user directly, even if the side plate 130 is opened due to the connection of the flow guide cover 300, it is not easy to affect the user experience.

[0050] In this embodiment, the flow guide cover 300 includes a front end and a rear end that are opposite in the front-rear direction. The front end faces the front panel 110, and the rear end faces the back plate 120. The front end of the flow guide cover 300 is connected to the fan bracket 210, and the rear end of the flow guide cover 300 is connected to the back plate 120.

[0051] Figure 8 It is a schematic diagram of the front end of the flow guide cover 300 in the first embodiment of this application. Combining Figure 5 and Figure 8 , in this embodiment, the flow guide cover 300 is a V-shaped flow guide cover. The flow guide cover 300 includes a first flow guide plate 310 and a second flow guide plate 320 that are arranged at an angle, and a front end plate 330 and a rear end plate 340 that are spaced apart in the front-rear direction. The front end plate 330 is connected to the front ends of the first flow guide plate 310 and the second flow guide plate 320, and the rear end plate 340 is connected to the rear ends of the first flow guide plate 310 and the second flow guide plate 320. The rear end plate 340 is connected to the back plate 120, and at least one of the first flow guide plate 310, the second flow guide plate 320, and the front end plate 330 is connected to the fan bracket 210.

[0052] Figure 9 For Figure 7An enlarged view of the local part IX. Optionally, one of the fairing 300 and the fan bracket 210 is provided with a clamping portion 211, and the other of the fairing 300 and the fan bracket 210 is provided with a clamping groove 361, and the clamping portion 211 is inserted and matched with the clamping groove 361. As Figure 9 shown, in this embodiment, the clamping groove 361 is provided at the front end of the fairing 300, and the clamping portion 211 is provided on the fan bracket 210; in other embodiments, the positions of the clamping groove 361 and the clamping portion 211 can be swapped. Specifically, a snap portion 360 protrudes from the upper edge of the front end plate 330, and the clamping groove 361 is formed on the snap portion 360.

[0053] Furthermore, one side of the fairing 300 in the left - right direction is connected to the fan bracket 210 through the clamping portion 211 and the clamping groove 361, and the other side of the fairing 300 in the left - right direction is connected to the fan bracket 210 through screws and / or rivets. In this way, the fairing 300 can be limited from both the left and right sides. And, one side uses the connection method of the clamping portion 211 and the clamping groove 361, and the other side uses the connection method of screws 350 and / or rivets, which can improve the loading and unloading efficiency of the fairing 300. In this embodiment, one side of the fairing 300 in the left - right direction uses screws 350 to connect to the fan bracket 210. Specifically, the snap portion 360 with the clamping groove 361 is arranged at one end of the upper edge of the front end plate 330 close to the second deflector 320, and the screw 350 is arranged on the first deflector 310. Further, the opening of the clamping groove 361 faces away from the direction where the screw 350 is located on the first deflector 310.

[0054] Through the above - mentioned setting method, the left and right sides of the front end of the fairing 300 are respectively connected through screws 350 and the clamping groove 361, and the rear end of the fairing 300 is connected to the back plate 120, thereby ensuring the installation stability of the fairing 300. The fairing 300 is not connected to the panel 110 through fasteners, which ensures the surface flatness of the panel 110, that is, improves the appearance beauty of the panel 110.

[0055] Figure 10 It is a disassembly schematic diagram of the fairing 300 in the second embodiment of the present application; Figure 11 It is a cross - sectional view of the range hood in the second embodiment of the present application. As Figure 10 and Figure 11 shown, the difference between this embodiment and the embodiment shown in Figure 7 is that the left and right sides of the fairing 300 are respectively connected to the fan bracket 210 using screws 350. Specifically, the first deflector 310 and the second deflector 320 are respectively connected to the fan bracket 210 through a screw 350, so that the fairing 300 has better stability.

[0056] It should be understood that in other embodiments, the structural form of the fairing 300 is not limited to the V-shaped structure in the above embodiments, and may also be other structural types that help improve the flow field and reduce noise. In other embodiments, the fairing 300 may also be connected to the fan bracket 210 and the panel 110 of the chassis 100 at the same time; in this case, compared with the practice of fixing the fairing 300 only by the chassis 100 in the related art, the stability of the fairing 300 can be further improved.

[0057] In summary, the embodiment of the present application provides a range hood, which includes a chassis 100, a fan assembly 200 and a fairing 300 disposed in the chassis 100. The chassis 100 has an air inlet 101 and an air outlet 102. The fan assembly 200 is connected to the chassis 100 through a fan bracket 210. The fairing 300 is located on the side of the fan assembly 200 close to the air inlet 101 and is connected to the fan bracket 210. By connecting the fairing 300 to the fan bracket 210, the fan bracket 210 can provide stable support for the fairing 300, so that the fairing 300 does not depend on being connected to the chassis 100 by more or larger fasteners (such as screws), thereby improving the aesthetic appearance of the outer surface of the chassis 100.

[0058] The foregoing is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes.
