[0044] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0045] Below with reference to Figures 1 - 9 Describe the fan assembly 100 of the range hood according to the embodiment of the present invention.

[0046] As Figures 1 - 3 shown, the fan assembly 100 of the range hood according to the embodiment of the present invention includes a volute 10, a wind wheel and a motor (not shown in the figure). The wind wheel is rotatably arranged in the volute 10, the motor is connected to the wind wheel, and the motor is used to drive the wind wheel to rotate. Among them, the axial direction of the volute 10 extends along the transverse direction, that is, the axial direction of the wind wheel extends along the transverse direction, and the axial direction of the motor shaft of the motor extends along the transverse direction. When the wind wheel works, external air can form an air flow under the drive of the wind wheel, and enter the volute 10 from the inlet 101 of the volute 10 along the axial direction of the volute 10, and be discharged from the air outlet 102 in the circumferential direction of the volute 10.

[0047] The fan assembly 100 of the range hood further includes a bracket 40. The bracket 40 is used to install the motor, and the bracket 40 can install the motor to the volute 10. Specifically, the bracket 40 has a plurality of support feet 4133, and the plurality of support feet 4133 are all connected to the volute 10. A flanging 410 extending away from the volute 10 is provided on the outer periphery of the support feet 4133. The flanging 410 can improve the structural strength of the support feet 4133, thereby improving the installation reliability and installation stability of the motor and ensuring the working reliability of the wind wheel.

[0048] Since the outer periphery of the support leg 4133 is provided with a flanging 410, a turning area is formed between the support leg 4133 and the flanging 410. When the turning area is at a low position, oil accumulation is likely to occur at this position and needs to be cleaned regularly. In this embodiment, an oil drain part 4101 is arranged at the low position of the flanging 410, which can drain away the oil remaining on the turning area, reduce the oil accumulation problem, thereby reducing the cleaning difficulty and the number of cleaning times, and improving the user experience.

[0049] For the fan assembly 100 of the range hood according to the embodiment of the present utility model, by arranging the oil drain part 4101 at the low position of the flanging 410, on the basis of ensuring the structural strength of the support leg 4133, the oil remaining on the turning area between the support leg 4133 and the flanging 410 can be drained away, reducing the oil accumulation problem, thereby reducing the cleaning difficulty and the number of cleaning times, and improving the user experience.

[0050] As Figures 2 - 3 and Figures 4 - 6 shown, in this embodiment, the oil drain part 4101 may include an oil drain hole 4102. The oil drain hole 4102 may be a round hole, a long strip hole or a special-shaped hole.

[0051] Due to the arrangement of the oil drain hole 4102, the edge of the side of the flanging 410 away from the support leg 4133 will not be damaged. Therefore, by setting the oil drain part 4101 as the oil drain hole 4102, the structural strength of the support leg 4133 will not be greatly affected. When the oil drain hole 4102 drains oil, the oil will not stick to the edge of the side of the flanging 410 away from the support leg 4133. Therefore, by setting the oil drain part 4101 to include the oil drain hole 4102, better oil drainage can be achieved on the basis of ensuring the structural strength of the support leg 4133.

[0052] As Figures 7 - 9 shown, in this embodiment, the oil drain part 4101 may include an oil drain notch 4103. By setting the oil drain part 4101 to include the oil drain notch 4103, the processing procedure of the oil drain part 4101 can be simplified, and the oil can be drained away better, further reducing the oil accumulation problem.

[0053] Among them, the number of the oil drain parts 4101 on the support leg 4133 at the low position may be one or more. In the embodiment where there is one oil drain part 4101 on the support leg 4133, the oil drain part 4101 may be an oil drain hole 4102 or an oil drain notch 4103; in the embodiment where there are multiple oil drain parts 4101 on the support leg 4133, all the multiple oil drain parts 4101 may be oil drain holes 4102, or all the multiple oil drain parts 4101 may be oil drain notches 4103, or a part of the oil drain parts 4101 may be oil drain holes 4102 and another part of the oil drain parts 4101 may be oil drain notches 4103.

[0054] It should be noted that one of the multiple supporting feet 4133 can be at a lower position, or two or more of the multiple supporting feet 4133 can be at a lower position. Among the multiple supporting feet 4133, an oil draining part 4101 is arranged at the lower position of the flanging 410 on each supporting foot 4133 at the lower position, which can better reduce the problem of oil accumulation.

[0055] As Figures 4 - 9 shown, according to some embodiments of the present invention, at least a part of the oil draining part 4101 is located at the connection position between the flanging 410 and the supporting foot 4133. By arranging the oil draining part 4101 at the connection position between the flanging 410 and the supporting foot 4133, the oil accumulated in the turning area between the flanging 410 and the supporting foot 4133 can be completely discharged, effectively solving the problem of oil residue.

[0056] As Figures 1 - 2 、 Figures 4 - 5 、 Figures 7 - 8 shown, according to some embodiments of the present invention, the bracket 40 includes a supporting strip 41. The middle part of the supporting strip 41 is connected to the motor, and both ends of the supporting strip 41 form supporting feet 4133 and are both connected to the volute 10. By setting the bracket 40 to include the supporting strip 41 with a strip structure, the structure of the bracket 40 can be simplified, which is convenient for processing and forming, and is beneficial to improving the production efficiency of the bracket 40.

[0057] As Figure 1 shown, in some embodiments, the supporting strip 41 extends vertically. The supporting foot 4133 at the lower end of the supporting strip 41 is the first supporting foot 4134, and the supporting foot 4133 at the upper end of the supporting strip 41 is the second supporting foot 4135. At least a part of the oil draining part 4101 is arranged on the flanging 410 on the outer periphery of the second supporting foot 4135.

[0058] The oil adhering to the supporting strip 41 can flow downward along the length direction of the supporting strip 41. When the oil flows to the flanging 410 on the outer periphery of the second supporting foot 4135, the oil can flow along the flanging 410 on the outer periphery of the second supporting foot 4135 and finally be discharged from the oil draining part 4101 at the lower position of the flanging 410, avoiding the accumulation of oil on the supporting strip 41.

[0059] In some embodiments, the number of the supporting strips 41 is at least two and includes a first supporting strip 411 and a second supporting strip 412. The first supporting strip 411 and the second supporting strip 412 are arranged circumferentially around the motor.

[0060] Specifically, both the first support bar 411 and the second support bar 412 can extend vertically, and the first support bar 411 and the second support bar 412 can be arranged at intervals in the horizontal direction. The middle parts in the length directions of the first support bar 411 and the second support bar 412 are both connected to the motor, and support feet 4133 are formed at both ends of the first support bar 411 and both ends of the second support bar 412, and they are all connected to the volute 10.

[0061] For the first support bar 411, the support foot 4133 at the lower end of the first support bar 411 is the first support bar 4134, the support foot 4133 at the upper end of the first support bar 411 is the second support foot 4135, and an oil drain part 4101 is provided at a low position of the flange 410 on the outer periphery of the second support foot 4135.

[0062] For the second support bar 412, the support foot 4133 at the lower end of the second support bar 412 is the first support bar 4134, the support foot 4133 at the upper end of the second support bar 412 is the second support foot 4135, and an oil drain part 4101 is provided at a low position of the flange 410 on the outer periphery of the second support foot 4135.

[0063] In the above technical solution, by setting the number of support bars 41 to at least two, it is beneficial to improve the installation reliability and stability of the motor, thereby ensuring the working reliability of the wind wheel.

[0064] In some embodiments, the flange 410 extends along the outer periphery of the support bar 41, that is, the flange 410 is not only provided on the outer periphery of the support foot 41, but also can be provided at other positions on the outer periphery of the support bar 41. Such a setting can further improve the structural strength of the support bar 41.

[0065] As Figure 4 shown, in some embodiments, the support bar 41 further includes a mounting part 4131 and two connecting parts 4132, that is, the support bar 41 includes a mounting part 4131, two connecting parts 4132 and two support feet 4133. One ends of the two connecting parts 4132 are respectively connected to both ends of the mounting part 4131, and the other ends of the two connecting parts 4132 are respectively connected to the two support feet 4133. The structure is simple and easy to form.

[0066] Among them, the motor is arranged on the mounting part 4131. For example, mounting holes 4151 are respectively provided at positions near both ends of the mounting part 4131. The motor can be fixed to the mounting part 4131 of the support bar 41 through a first fastener (not shown in the figure) passing through the mounting holes 4151. Fixing holes 4152 are provided on both support bars 4133 of the support bar 41, and the support bar 41 can be fixed to the volute 10 through a second fastener (not shown in the figure) passing through the fixing holes 4152.

[0067] In some examples, the installation part 4131 extends into the volute 10 from the inlet 101 of the volute 10, and the connection part 4132 passes through the inlet 101 of the volute 10 to extend from inside the volute 10 to outside the volute 10.

[0068] For example, the connection part 4132 can form a bending structure; for another example, the connection part 4132 can be perpendicular to the installation part 4131 and the support leg 4133; for yet another example, the connection part 4132 can be inclined with respect to the installation part 4131 and the support leg 4133. As Figure 2 and Figure 4 shown, in this embodiment, a part of the connection part 4132 extends obliquely from inside the volute 10 to outside the volute 10 in a direction away from the installation part 4131.

[0069] In the above technical solution, by setting the connection part 4132 as the above structure, a part of the motor can extend into the volute 10 from the inlet 101 of the volute 10. On the one hand, it can facilitate the connection between the motor and the wind wheel, and on the other hand, it can reduce the size of the fan assembly in the axial direction of the volute and reduce the occupied space of the fan assembly.

[0070] As Figure 4 shown, in some examples, the installation part 4131 is an arc bent in a direction away from the center of the motor. With such a setting, on the one hand, it can increase the contact area between the motor and the installation part 4131, thereby improving the connection reliability between the motor and the support bar 41, and on the other hand, it can make the contour of the side of the installation part 4131 away from the center of the motor match the outer contour of the motor, so as to support the motor more reliably.

[0071] In some examples, the width of the support leg 4133 gradually increases in a direction away from the connection part 4132. For example, the support leg 4133 can generally form a trapezoidal structure. With such a setting, it is beneficial to improve the structural strength and anti-deformation ability of the support leg 4133, thereby improving the connection reliability between the support bar 41 and the volute 10 and ensuring the installation reliability and stability of the motor.

[0072] As Figure 4 and Figure 5 shown, in some examples, the support bar 41 is provided with a structure strengthening part, and at least one structure strengthening part is located at the installation part 4131, the connection part 4132, the connection position between the connection part 4132 and the installation part 4131, or the connection position between the connection part 4132 and the support leg 4133.

[0073] Specifically, at least one structural reinforcement is the first structural reinforcement 4141. The first structural reinforcement 4141 can be located at the mounting portion 4131, and the first structural reinforcement 4141 can extend along the extending direction of the mounting portion 4131. For example, if the mounting portion 4131 is formed as an arc bent away from the center of the motor, the first structural reinforcement 4141 can also be formed as an arc bent away from the center of the motor.

[0074] Of course, at least one structural reinforcement can be the second structural reinforcement 4142. The second structural reinforcement 4142 is located at the connecting portion 4132, and the second structural reinforcement 4142 can extend along the extending direction of the connecting portion 4132; alternatively, at least one structural reinforcement can be a third structural reinforcement (not shown in the figure). The third structural reinforcement is located at the support leg 4133, and the third structural reinforcement extends along the extending direction of the support leg 4133.

[0075] Among them, in the embodiment where the second structural reinforcement 4142 is provided at the connecting portion 4132, the second structural reinforcement 4142 can at least partially extend to the connection position between the connecting portion 4132 and the mounting portion 4131; and / or, the second structural reinforcement 4142 can at least partially extend to the connection position between the connecting portion 4132 and the support leg 4133.

[0076] In the above technical solution, by setting the structural strength on the support bar 41, the structural strength and anti-deformation ability of the support bar 41 can be improved, thereby ensuring the installation reliability and stability of the motor, and further ensuring that the fan assembly 100 can work properly.

[0077] In some specific examples, the structural reinforcement is a reinforcing recess or a reinforcing protrusion, which has a simple structure and is convenient for processing.

[0078] Such as Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, one axial end of the volute 10 has an end wall 11. The end wall 11 is provided with an opening, and the outer surface of the end wall 11 has a recess (not shown in the figure) surrounding the opening. By providing a recess on the end wall 11, that is, by processing and pressing on the end wall 11 of the volute 10, it is beneficial to improve the structural strength and anti-deformation ability of the end wall 11 of the volute 10, thereby improving the installation reliability and stability of the motor.

[0079] Among them, the support leg 4133 is connected to the bottom wall of the recess, and the part of the side wall of the recess at a lower position gradually extends downward away from the bottom wall of the recess.

[0080] In the above technical solution, by providing a recess on the end wall 11 of the volute 10, it is beneficial to improve the structural strength of the end wall 11 of the volute 10, thereby enhancing the reliability of use of the volute 10; by gradually extending downward the part of the side wall of the recess at a lower position away from the bottom wall of the recess, even if oil drops onto the recess of the volute 10, the oil will flow down along the side wall of the recess from the part of the side wall of the recess at a lower position, further reducing the problem of oil accumulation in the volute 10.

[0081] The following describes the range hood 500 according to an embodiment of the present invention with reference to the accompanying drawings.

[0082] As Figure 10 shown, the range hood 500 according to an embodiment of the present invention includes the fan assembly 100 of the range hood according to the above embodiment.

[0083] Since the fan assembly 100 of the range hood according to an embodiment of the present invention has the above technical effects, the range hood 500 according to an embodiment of the present invention also has the above technical effects. By adopting the fan assembly 100 of the above range hood, the problem of oil accumulation can be reduced, the cleaning difficulty and the number of cleaning times can be reduced, and the user experience can be improved.

[0084] In some embodiments, the range hood 500 includes a range hood body 51. The range hood body 51 defines an upper suction cavity and a lower suction cavity. The upper suction cavity has a lower opening, and the lower opening forms an upper suction port. The lower suction cavity has a side opening (such as a front side opening, that is, an opening on the side facing the user), and the side opening forms a lower suction port 512.

[0085] Among them, the fan assembly 100 can be arranged in the upper suction cavity. When the range hood 500 works, external oil fume can enter the upper suction cavity from the upper suction port and the lower suction cavity from the lower suction port 512 under the action of the fan assembly 100, and finally be discharged from the oil fume discharge port 513 of the range hood 500.
