Description

TECHNICAL FIELD

[0001] The utility model relates to range hood technical field, specifically, a kind of motor support, damping component, motor assembly and range hood. BACKGROUND

[0002] With the improvement of people's living quality, the requirement of kitchen cooking environment is also increasing. Range hood has become one of the indispensable kitchen household appliances in modern family. Range hood mostly includes motor assembly, and the motor assembly is the core of the power part of range hood. However, the motor assembly in the existing range hood is prone to vibration during operation, causing unnecessary noise, which not only affects the cooking experience of users, but also may harm the physical and mental health of users.

[0003] In order to reduce noise, in the existing motor assembly, elastic gasket is mostly arranged between motor and motor support to reduce vibration generated during operation. However, this scheme has limited buffering effect on axial vibration generated by motor, and cannot solve the radial runout caused by motor radial vibration and insufficient dynamic balance of impeller, and the vibration generated by motor during operation is also transmitted to the volute through the supporting leg of the motor support, resulting in increased noise. SUMMARY

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a motor support is provided, and the technical scheme is as follows.

[0005] The motor support includes a ring-shaped body, at least two supporting legs and at least two first arc-shaped flange portions. The ring-shaped body has a first face and a second face arranged opposite to each other. The supporting legs are at least partially located on the side of the first face. The first arc-shaped flange portions are at least partially located on the side of the second face, and the at least two first arc-shaped flange portions are surrounded by the ring-shaped body to form a containing portion.

[0006] The motor support of the utility model can effectively cancel out the radial vibration generated by the motor when applied to the damping component and connected with the motor, and can disperse part of the axial vibration generated by the motor to the radial direction to cancel it out, avoiding the vibration generated by the motor during operation being transmitted to the volute through the supporting leg, thereby preventing the occurrence of increased noise. In this way, the damping effect is improved, and the noise is reduced.

[0007] Exemplarily, mounting holes are formed in the first arc-shaped flange portions. In this way, when applied to the damping component, the mounting holes improve the stability of the mounting and cooperation of the first arc-shaped flange portions and other components of the damping component.

[0008] Exemplarily, the first arc-shaped flanging portion has an angle a1 of 135°-150° with the annular body. In this way, when the angle a1 is within this range, the radial vibration generated by the motor can be effectively reduced when the damping assembly is applied to the motor, and the axial vibration generated by the motor can be effectively dispersed in the radial direction to reduce the axial vibration, thereby achieving a better damping effect.

[0009] Exemplarily, the first arc-shaped flanging portion has a central angle b1 of 30°-60°. In this way, when the central angle b1 is within this range, the radial vibration generated by the motor can be effectively reduced when the damping assembly is applied to the motor, and the axial vibration generated by the motor can be further reduced by converting part of the axial vibration into radial vibration, thereby achieving a better damping effect and ensuring the stability of the connection between the first arc-shaped flanging portion and the annular body.

[0010] Exemplarily, the first arc-shaped flanging portion has a flanging length L1 of 10mm-20mm. In this way, when the flanging length L1 is within this range, the radial vibration generated by the motor can be effectively reduced when the damping assembly is applied to the motor, and the axial vibration can be further reduced by converting part of the axial vibration into radial vibration, thereby achieving a better damping effect and ensuring the strength of the first arc-shaped flanging portion.

[0011] Exemplarily, the at least two legs and the at least two first arc-shaped flanging portions are spaced apart along the circumference of the annular body, and one first arc-shaped flanging portion is arranged between every two adjacent legs in the circumferential direction of the annular body. In this way, the first arc-shaped flanging portion is not too close to the leg, which avoids interfering with the installation of other components, and the first arc-shaped flanging portion is not an integral structure with the leg. When the damping assembly is applied to the motor, the vibration generated by the motor during operation is transmitted to the volute through the leg, which avoids the occurrence of a large noise.

[0012] According to another aspect of the utility model, provide a kind of shock-absorbing assembly, the shock-absorbing assembly includes elastic pad, compression piece and the motor support as described above, elastic pad is pressed in the accommodating portion by compression piece, elastic pad has annular pad body and at least two second arc-shaped flanging parts, annular pad body has oppositely arranged third face and fourth face, third face is attached with second face, at least two second arc-shaped flanging parts are at least partially located on the side of fourth face, and at least two second arc-shaped flanging parts and at least two first arc-shaped flanging parts are respectively attached one by one corresponding. Thus, when the shock-absorbing assembly is applied to motor assembly, the second arc-shaped flanging part of elastic pad is pressed in the accommodating portion by compression piece, the interaction between compression piece, first arc-shaped flanging part and second arc-shaped flanging part can effectively offset the radial vibration generated by motor, and part of the axial vibration generated by motor can be dispersed to radial to offset it, so as to improve the shock-absorbing effect, and then reduce noise.

[0013] Exemplarily, compression piece has arc-shaped body, third arc-shaped flanging part is formed on arc-shaped body, and second arc-shaped flanging part is pressed and attached to first arc-shaped flanging part by third arc-shaped flanging part. Thus, when applied to motor assembly, third arc-shaped flanging part can press and attach second arc-shaped flanging part to first arc-shaped flanging part, and the interaction between the three arc-shaped flanging parts can effectively offset the radial vibration generated by motor, and part of the axial vibration generated by motor can be dispersed to radial to offset it, so as to improve the shock-absorbing effect.

[0014] Exemplarily, the central angle β2 of third arc-shaped flanging part is 20°-45°. Thus, the central angle β2 is in the range, third arc-shaped flanging part can be more attached to first arc-shaped flanging part and second arc-shaped flanging part, so that third arc-shaped flanging part can better press and attach second arc-shaped flanging part to first arc-shaped flanging part, and the stability of the connection between third arc-shaped flanging part and arc-shaped body is ensured.

[0015] Exemplarily, mounting hole is formed on first arc-shaped flanging part, and protrusion is protruded on one side of second arc-shaped flanging part towards first arc-shaped flanging part, and protrusion is arranged in mounting hole. Thus, second arc-shaped flanging part is fixedly connected to first arc-shaped flanging part, so that they are more attached, and the stability of mounting cooperation between them is improved.

[0016] Exemplarily, mounting hole penetrates first arc-shaped flanging part, and part of protrusion is protruded outside mounting hole. Thus, the stability of mounting cooperation between first arc-shaped flanging part and second arc-shaped flanging part is further improved.

[0017] According to the motor assembly of the utility model, the shock pad is arranged between the compression piece and the first connecting part, and the first fastener sequentially passes through and connects the compression piece, the shock pad, the first connecting part, the annular pad body and the annular body, so that the vibration transmitted by the motor to the motor support is effectively reduced, the noise generated during the operation of the motor assembly is reduced, the installation is convenient, and the use experience of the user is improved.

[0018] Exemplarily, a shock pad is arranged between the compression piece and the first connecting part, and the first fastener sequentially passes through and connects the compression piece, the shock pad, the first connecting part, the annular pad body and the annular body. In this way, the vibration between the compression piece and the first connecting part during the operation of the motor is avoided, so that the noise is not generated.

[0019] According to another aspect of the utility model, a range hood is provided, the range hood comprises a volute and the motor assembly, the volute is provided with a second connecting part, the supporting leg is provided with a fixed part on the side where the first surface is located, and the second connecting part is connected with the fixed part. Since the motor assembly has the beneficial effects described above, the range hood comprising the motor assembly also has the beneficial effects described above, which will not be repeated here.

[0035] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0036] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0037] An embodiment of this utility model provides a motor bracket. According to another aspect of this utility model, a shock-absorbing component is provided, in which the motor bracket can be applied. Further, according to yet another aspect of this utility model, a motor assembly is provided, in which the shock-absorbing component can be applied. The motor assembly provided by this utility model can be applied to a range hood. The motor bracket, shock-absorbing component, motor assembly, and range hood provided according to this utility model will be described in detail below with reference to the accompanying drawings.

[0038] See also Figure 1 and Figure 2 The motor bracket 110 may include an annular body 111, at least two legs 112, and at least two first arc-shaped flanges 113. The annular body 111 may have a first surface 1111 and a second surface 1112 disposed opposite to each other. The legs 112 may be at least partially located on the side where the first surface 1111 is located. The first arc-shaped flanges 113 may be at least partially located on the side where the second surface 1112 is located, and at least two first arc-shaped flanges 113 enclose the annular body 111 to form a receiving portion 114.

[0039] The motor bracket 110 of this utility model, based on the first arc-shaped flange 113, when applied to the vibration damping assembly 100 and connected to the motor 101, allows the elastic pad 120 to be placed within the receiving portion 114. This effectively cancels out the radial vibration generated by the motor 101 and disperses some of the axial vibration generated by the motor 101 radially to cancel it out. This prevents the vibration generated by the motor 101 during operation from being transmitted to the volute 20 through the support leg 112, thus avoiding increased noise. In this way, the vibration damping effect is improved and noise is reduced.

[0040] In some embodiments, the support leg 112 may have a first end 1121 and a second end 1122. The first end 1121 may be connected to the first surface 1111, and both the first end 1121 and the second end 1122 may be located on the side where the first surface 1111 is located. The first arc-shaped flange portion 113 may form an arc segment around the annular body 111, and the first arc-shaped flange portion 113 may extend from the outer edge of the annular body 111 toward the side where the second surface 1112 is located. This facilitates the connection between the motor bracket 110 and the volute 20, and also facilitates the cooperation between the first arc-shaped flange portion 113 and other components in the motor 101 and the shock absorption assembly 100. Of course, the first end 1121 may also be connected to the second surface 1112, and the second end 1122 may be located on the side where the first surface 1111 is located; or the support leg 112 may extend from the outer edge of the annular body 111 toward the side where the first surface 1111 is located, etc. It is also possible that the first arc-shaped flange 113 can be a plate-like component; one end of the plate-like component can be connected to the second surface 1112, and both ends can be located on the side where the second surface 1112 is located; or one end of the plate-like component can be connected to the first surface 1111, and the other end is located on the side where the second surface 1112 is located, etc. In summary, the support leg 112 and the annular body 111, as well as the first arc-shaped flange 113 and the annular body 111, can be an integral structure or a separate structure. When the support leg 112 and the annular body 111, as well as the first arc-shaped flange 113 and the annular body 111, are separate structures, their connection methods can be adhesive, screw connection, etc., and no specific limitation is made here.

[0041] Preferably, the number of first arc-shaped flanges 113 can be four, which can effectively improve the shock absorption effect. Of course, the number of first arc-shaped flanges 113 can also be three, five, or six, etc.

[0042] In an embodiment not shown in the figure, at least part of the end of the first arc-shaped flange 113 connected to the annular body 111 can also be an arc segment to enhance the damping effect on axial vibration.

[0043] See Figure 1 The first arc-shaped flange 113 may have mounting holes 1131. There may be one or more mounting holes 1131. When applied to the damping assembly 100, the mounting holes 1131 improve the stability of the installation and fit between the first arc-shaped flange 113 and other components of the damping assembly 100. Preferably, for ease of installation or manufacturing, the mounting holes 1131 may be located in the middle of the first arc-shaped flange 113.

[0044] See Figure 2An angle α1 can be formed between the first arc-shaped flange 113 and the annular body 111. The angle α1 can be 135° to 150°, for example, α1 can be 135°, 145°, 150°, etc. When the angle α1 is within this range, when applied to the vibration damping assembly 100 and connected to the motor 101, it is effective in canceling out the radial vibration generated by the motor 101, and it is also effective in dispersing part of the axial vibration generated by the motor 101 radially to cancel it out, thereby achieving a better vibration damping effect.

[0045] See again Figure 1 The central angle β1 opposite to the first arc-shaped flange 113 can be 30° to 60°, for example, 30°, 45°, 60°, etc. When the central angle β1 is within this range, it can effectively reduce the radial vibration generated by the motor 101 when applied to the vibration damping assembly 100 and connected to the motor 101. Furthermore, by converting part of the axial vibration into radial vibration, the influence of axial vibration is further reduced, thereby achieving a better vibration damping effect and ensuring the stability of the connection between the first arc-shaped flange 113 and the annular body 111.

[0046] See again Figure 2 The first arc-shaped flange 113 may have a flange length L1. The flange length L1 may be 10mm to 20mm, for example, 10mm, 15mm, 20mm, etc. Within this range, when applied to the vibration damping assembly 100 and connected to the motor 101, the flange length L1 can effectively reduce the radial vibration generated by the motor 101, and further reduce the axial vibration by converting part of the axial vibration into radial vibration, thereby achieving a better vibration damping effect and ensuring the strength of the first arc-shaped flange 113.

[0047] See again Figure 1 At least two support legs 112 and at least two first arc-shaped flanges 113 can be spaced apart circumferentially along the annular body 111, and one first arc-shaped flange 113 can be provided between every two adjacent support legs 112 along the circumferential direction of the annular body 111. This avoids the first arc-shaped flanges 113 being too close to the support legs 112, thus preventing obstruction of other component installation, and also avoids the situation where the first arc-shaped flanges 113 and support legs 112 are an integral structure. In this case, when applied to the vibration damping assembly 100 and connected to the motor 101, the vibration generated by the motor 101 during operation would be transmitted to the volute 20 through the support legs 112, resulting in significant noise.

[0048] See also Figures 1 to 5According to another aspect of the present invention, a shock-absorbing assembly 100 is provided. The shock-absorbing assembly 100 may include an elastic pad 120, a pressing member 130, and a motor bracket 110 as described above. The elastic pad 120 can be pressed against the receiving portion 114 by the pressing member 130. The elastic pad 120 may have an annular pad body 121 and at least two second arcuate flange portions 122. The annular pad body 121 may have a third surface 1211 and a fourth surface 1212 disposed opposite to each other. The third surface 1211 and the second surface 1212 can be abutted. The second arcuate flange portions 122 are at least partially located on the side where the fourth surface 1212 is located, and at least two second arcuate flange portions 122 can be abutted against at least two first arcuate flange portions 113 respectively. Understandably, the number of first arcuate flange portions 113 and second arcuate flange portions 122 may be the same. Thus, when the shock-absorbing component 100 is applied to the motor assembly 10, the second arc-shaped flange 122 of the elastic pad 120 is pressed against the receiving portion 114 by the pressing member 130. The interaction between the pressing member 130, the first arc-shaped flange 113, and the second arc-shaped flange 122 can effectively cancel out the radial vibration generated by the motor 101, and can also disperse part of the axial vibration generated by the motor 101 to the radial direction to cancel it out, thereby improving the shock absorption effect and reducing noise.

[0049] Specifically, the elastic pad 120 can be made of rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the elastic pad 120 can also be made of other materials. The second arc-shaped flange 122 and the annular pad body 121 can be an integral structure, and the second arc-shaped flange 122 can extend from the outer edge of the annular pad body 121. Of course, it is not excluded that the second arc-shaped flange 122 and the annular pad body 121 can be a separate structure. For example, one end of the second arc-shaped flange 122 can be connected to the third surface 1211, and both ends can be located within the receiving portion 114; or one end of the second arc-shaped flange 122 can be connected to the fourth surface 1212, and both ends can be located within the receiving portion 114, etc. When the second arc-shaped flange 122 and the annular pad body 121 are separate structures, their connection method can be adhesive, screw connection, etc., which are not specifically limited here.

[0050] Furthermore, the annular pad body 121 and the annular body 111 can have similar shapes to ensure shock absorption and facilitate connection with the motor 101. The second arc-shaped flange 122 and the first arc-shaped flange 113 can have similar shapes to facilitate their fit. The angle between the second arc-shaped flange 122 and the annular pad body 121 can be the same as the angle α1 between the first arc-shaped flange 113 and the annular body 111. The flange length of the second arc-shaped flange 122 can be the same as the flange length L1 of the first arc-shaped flange 113. This further improves the shock absorption effect.

[0051] See also Figures 1 to 7 The pressing part 130 may have an arc-shaped body 131. A third arc-shaped flange 132 may be formed on the arc-shaped body 131. The second arc-shaped flange 122 can be pressed against and attached to the first arc-shaped flange 113 by the third arc-shaped flange 132. When applied to the motor assembly 10, the third arc-shaped flange 132 can press the second arc-shaped flange 122 against and attach to the first arc-shaped flange 113. Through the interaction between the three arc-shaped flanges, the radial vibration generated by the motor 101 can be effectively canceled out, and part of the axial vibration generated by the motor 101 can be dispersed radially to cancel it out, thereby improving the vibration reduction effect.

[0052] Specifically, the third arc-shaped flange 132 and the arc-shaped body 131 can be an integral structure, with the third arc-shaped flange 132 extending from the outer edge of the arc-shaped body 131. Of course, it is not excluded that the third arc-shaped flange 132 and the arc-shaped body 131 can be separate structures; for example, one end of the third arc-shaped flange 132 can be connected to the end face near the fourth surface 1212; or one end of the third arc-shaped flange 132 can be connected to the end face away from the fourth surface 1212. When the third arc-shaped flange 132 and the arc-shaped body 131 are separate structures, their connection method can be adhesive, screw connection, etc., and is not specifically limited here.

[0053] Preferably, there can be multiple pressing parts 130, each of which can be a small plate-shaped part for easy maintenance or replacement. Understandably, the number of pressing parts 130 can be the same as the number of the first arc-shaped flange 113 and the second arc-shaped flange 122. Of course, it is not excluded that the pressing part 130 may have an annular arc-shaped body 131 corresponding to the annular body 111, and a third arc-shaped flange 132 may be provided at the position corresponding to the first arc-shaped flange 113.

[0054] See also Figure 3 , Figure 6 and Figure 7The central angle β2 opposite to the third arc-shaped flange 132 can be 20° to 45°, for example, the central angle β2 can be 20°, 30°, 45°, etc. Within this range of central angle β2, the third arc-shaped flange 132 can fit more closely with the first arc-shaped flange 113 and the second arc-shaped flange 122, so that the third arc-shaped flange 132 can better press the second arc-shaped flange 122 against the first arc-shaped flange 113, and also ensure the stability of the connection between the third arc-shaped flange 132 and the arc-shaped body 131.

[0055] Specifically, the shape of the third arc-shaped flange 132 can be similar to that of the first arc-shaped flange 113, so that the third arc-shaped flange 132 can better press and adhere the second arc-shaped flange 122 to the first arc-shaped flange 113. The angle between the third arc-shaped flange 132 and the arc-shaped body 131 can be the same as the angle between the second arc-shaped flange 122 and the annular pad body 121. The flange length of the third arc-shaped flange 132 can be the same as the flange length of the second arc-shaped flange 122. In this way, the third arc-shaped flange 132 plays a better pressing role, further improving the shock absorption effect.

[0056] See also Figure 1 and Figure 5 The first arc-shaped flange 113 may have a mounting hole 1131. The second arc-shaped flange 122 may have a protrusion 1221 on the side facing the first arc-shaped flange 113. The protrusion 1221 can pass through the mounting hole 1131. The second arc-shaped flange 122 is fixedly connected to the first arc-shaped flange 113, making them fit better and improving the stability of their installation. Understandably, the mounting hole 1131 can be a blind hole. The protrusion 1221 and the second arc-shaped flange 122 can be an integral structure. The protrusion 1221 and the second arc-shaped flange 122 can also be separate structures, and their connection method can be adhesive, screw connection, etc., which are not specifically limited here.

[0057] See Figure 9 The mounting hole 1131 can pass through the first arc-shaped flange 113. A portion of the protrusion 1221 can extend out of the mounting hole 1131. This further improves the stability of the mounting fit between the first arc-shaped flange 113 and the second arc-shaped flange 122, and prevents the protrusion 1221 from dislodging from the mounting hole 1131 during the operation of the motor 101.

[0058] In embodiments not shown in the figure, the connection between the first arc-shaped flange 113 and the second arc-shaped flange 122 can be varied, such as by pasting; or by the first arc-shaped flange 113 forming a slot, and the second arc-shaped flange 122 being inserted into the slot, etc.; it can be ensured that the second arc-shaped flange 122 and the first arc-shaped flange 113 remain in a close fit during the operation of the motor 101.

[0059] See also Figure 8 and Figure 9 According to another aspect of the present invention, a motor assembly 10 is provided. The motor assembly 10 may include a motor 101 and a shock-absorbing assembly 100 as described above. The motor 101 may have a first connecting portion 1011 and a first fastener 102. The first fastener 102 may sequentially pass through and connect a pressing member 130, the first connecting portion 1011, the annular pad body 121, and the annular body 111. The number of first connecting portions 1011 may be one or more. Preferably, to reduce the vibration transmitted from the motor 101 to the motor bracket 110, the first connecting portion 1011 may be a plurality of flange structures. Of course, it is not excluded that when the number of first connecting portions 1011 is one, an annular flange structure may be formed around the circumference of the motor 101. It should be noted that the number of first arc-shaped flange portions 113 may be the same as the number of first connecting portions 1011. In this way, the shock-absorbing assembly 100 effectively reduces the vibration transmitted from the motor 101 to the motor bracket 110, thereby reducing the noise generated during the operation of the motor assembly 10, while also facilitating installation and improving the user experience. Since the shock-absorbing component 100 described above has the aforementioned beneficial effects, the motor assembly 10 including the shock-absorbing component 100 described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0060] For example, a shock-absorbing pad (not shown) may be provided between the pressing member 130 and the first connecting portion 1011. A first fastener 102 may pass through and connect the pressing member 130, the shock-absorbing pad, the first connecting portion 1011, the annular pad body 121, and the annular body 111 in sequence. This avoids noise caused by vibration between the pressing member 130 and the first connecting portion 1011 during operation of the motor 101. The shock-absorbing pad can be made of rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the shock-absorbing pad can also be made of other materials.
