Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor assembly and an air conditioner. Background Art

[0002] The outdoor unit of a split air conditioner is placed outdoors. Therefore, the motor of the outdoor unit is at risk of being eroded by rainwater. After the rainwater enters the motor, it may cause the stator core, rotor core, bearings and other structures inside the motor to rust, reducing its service life. At the same time, it may also cause a short circuit. Due to the relationship between its own structure and the requirements of production line assembly efficiency, some motors cannot be provided with a sealing gasket between the motor housing and the end cover. Therefore, it is usually necessary to rely on the abutting fit between the end cover and the housing to ensure the protection effect. However, since the connection between the end cover and the housing is a hard connection, the protection effect is limited, and the motor still has a risk of water ingress.

[0042] Refer to Figure 1 As shown, a motor assembly 1000 of an embodiment of the present utility model can be used on household appliances such as air conditioners, refrigerators, humidifiers, etc. Taking an air conditioner as an example, the air conditioner is a split air conditioner. The outdoor unit of the split air conditioner includes the motor assembly 1000, and the motor assembly 1000 is used to drive the axial flow fan to rotate for dissipating heat from the heat exchanger. The motor assembly 1000 of the embodiment of the present utility model includes: a motor body 100, a bracket 200, and a seal 300. Refer to Figure 2 As shown, the motor body 100 includes a housing 110 and an end cover 120. A cavity 111 is formed inside the housing 110, and the cavity 111 is used to install structures such as a rotor 140 and a stator 130. The end cover 120 is connected to one end of the housing 110 and seals one end of the cavity 111, thereby playing a protective role to reduce the situation of dust, water, insects, etc. entering the cavity 111. An abutting portion 112 is provided around the outer side wall of the housing 110. The abutting portion 112 is in a sheet-like structure and extends along the radial direction of the motor body 100.

[0043] Refer to Figure 3As shown, the bracket 200 is used for fixedly connecting with the motor body 100. A groove 210 is formed by recessing one side of the bracket 200, and the groove 210 is used for accommodating the end cover 120. The bracket 200 includes a mounting portion 220, the mounting portion 220 is arranged around the opening of the groove 210, the mounting portion 220 and the abutting portion 112 are arranged at intervals along the axial direction of the motor body 100, and a mounting groove 230 is formed between the mounting portion 220 and the abutting portion 112. Refer to Figure 4 As shown, the seal 300 includes a first sealing rib 310, and the first seal 300 is in an arc-shaped strip or in a ring shape.

[0044] Refer to Figure 5 and Figure 6 As shown, the first sealing rib 310 is arranged in the mounting groove 230 and abuts against the mounting portion 220 and the abutting portion 112. Therefore, the first sealing rib 310 seals at least the part of the mounting groove 230 above the rotation axis of the motor body 100, that is, at least part of the structure of the first sealing rib 310 is installed in the upper groove section of the mounting groove 230, and both sides of the first sealing rib 310 abut against the mounting portion 220 and the abutting portion 112 respectively, so as to achieve the function of sealing and waterproofing. The upper groove section refers to: when the motor assembly 1000 is in the installation position, the part of the mounting groove 230 above the horizontal plane where the rotation axis of the motor assembly is located. Among them, the installation position is the position when the motor assembly 1000 is installed in the household appliance, that is, the position where the motor assembly 1000 is in the working state.

[0045] For example, when the first sealing rib 310 is in a ring shape, the first sealing rib 310 is sleeved on the housing 110 and seals the entire mounting groove 230. When the first sealing rib 310 is in an arc-shaped strip, the first sealing rib 310 seals part of the structure of the mounting groove 230.

[0046] By adopting the above scheme, since at least part of the structure of the first sealing rib 310 is installed in the upper groove section of the mounting groove 230, and the end cover 120 is located in the groove 210, it can effectively prevent water flow from entering the gap 121 between the end cover 120 and the housing 110 through the mounting groove 230, so as to improve the waterproof effect of the motor. At the same time, the first sealing rib 310 does not need to be arranged in the gap 121 between the end cover 120 and the housing 110, which has little impact on the production and manufacturing of the motor body 100. And the first sealing rib 310 has elasticity and is installed between the mounting portion 220 and the abutting portion 112, and can also play a damping effect, effectively reducing the situation that the vibration of the motor is transmitted to the bracket 200, thereby reducing the noise generated during the operation of the motor and improving the user experience. Therefore, while having a sealing effect, the first sealing rib 310 also plays a damping role, which can simplify the structure of the motor assembly 1000 and improve the assembly efficiency.

[0047] Among them, the reason why at least part of the structure of the first sealing rib 310 is installed in the upper groove section of the installation groove 230 is as follows: When water flow wants to enter the cavity 111 through the gap 121 between the end cover 120 and the outer shell 110, it needs to pass through the installation groove 230 first. After the first sealing rib 310 seals the upper half of the installation groove 230, the water flow can only possibly contact the gap 121 between the end cover 120 and the outer shell 110 below the installation groove 230. Under the action of gravity, the water flow cannot enter the cavity 111 through the gap 121. Therefore, the first sealing rib 310 only needs to seal the upper half of the installation groove 230, which can save materials, reduce production costs, and facilitate installation.

[0048] Referring to Figure 6 As shown, in the embodiment of the present utility model, the bracket 200 is recessed to form a flanging 211 and a retaining edge 212. The flanging 211 is arranged around the end cover 120 at intervals. The flanging 211 extends axially, and both ends of the flanging 211 are respectively connected with an installation part 220 and a retaining edge 212. The installation part 220 is located outside the flanging 211 and extends radially; the retaining edge 212 is located inside the flanging 211 and extends radially. The flanging 211 and the baffle enclose to form a groove 210. When the end cover 120 and part of the outer shell 110 are located in the groove 210, both the flanging 211 and the retaining edge 212 can play a role in blocking the water flow to improve the protection effect on the motor body 100.

[0049] In order to further improve the waterproof effect of the motor body 100, referring to Figure 4 and Figure 6 As shown, in the embodiment of the present utility model, a gap 121 is formed between the outer shell 110 and the end cover 120. The sealing member 300 further includes a second sealing rib 320. The second sealing rib 320 is connected to the axial end wall of the first sealing rib 310 and extends along the axis of the motor body 100. The end wall of the first sealing rib 310 refers to the wall surfaces at both ends along the axis of the motor body 100. The second sealing rib 320 is located between the side wall of the groove 210 and the outer side wall of the outer shell 110, and at least part of the structure of the second sealing rib 320 covers the upper half section of the gap 121. The upper half section refers to the part of the gap 121 above the horizontal plane where the rotation axis is located when the motor assembly is in the installation position. For example, the second sealing rib 320 is annular, the second sealing rib 320 surrounds the gap 121 and covers and seals the entire gap 121; or the second sealing rib 320 is in the shape of an arc-shaped strip, covering and sealing a part of the gap 121.

[0050] It can be understood that since the second sealing rib 320 of this embodiment is located on the outer sides of the end cover 120 and the housing 110, the seal 300 can be assembled when the motor body 100 is installed on the bracket 200. Therefore, it is not necessary to provide a sealing ring in the gap 121 during the production and manufacturing process of the motor body 100. By providing the second sealing rib 320 to cover and seal the gap 121, the situation of water flowing into the accommodation cavity through the gap 121 can be further reduced, so as to improve the waterproof effect and safety of the motor body 100.

[0051] Referring to Figure 6 As shown, in the embodiment of the present utility model, along the axial direction of the motor body 100, the distance between the side wall of the groove 210 and the outer side wall of the housing 110 gradually decreases in the direction away from the housing 110. Therefore, when installing the motor body 100, during the process of pushing the motor body 100 into the groove 210, the side wall of the groove 210, the outer side wall of the housing 110, and the outer side wall of the end cover 120 will squeeze the second sealing rib 320, so that the second sealing rib 320 fits and seals the gap 121 with the outer side wall of the housing 110 and the outer side wall of the end cover 120, further improving the sealing effect of the second sealing rib 320. As an alternative embodiment, glue can also be provided between the second sealing rib 320 and the outer side wall of the housing 110 and the outer side wall of the end cover 120, so that the second sealing rib 320 seals the gap 121.

[0052] To avoid water accumulation in the installation groove 230, referring to Figure 6 as shown, Figure 6 The dotted arrows in it indicate the direction of water flow. In the embodiment of the present utility model, along the radial direction of the motor body 100, the outer side wall of the first sealing rib 310 is flush with the outer side wall of the abutting portion 112, or the outer side wall of the first sealing rib 310 protrudes from the outer side wall of the abutting portion 112. It can be understood that when water flows through the outer side wall of the first sealing rib 310, it will flow downward along the first sealing rib 310, or cross the abutting portion 112 and then flow through the outer side wall of the housing 110 and finally flow downward. Therefore, it can effectively avoid the adverse effects such as bacterial growth, dampness, and mildew caused by water accumulation in the installation groove 230.

[0053] Referring to Figure 2 、 Figure 3 and Figure 4As shown, in the embodiment of the present utility model, a plurality of mounting feet 113 are provided on the outer side wall of the housing 110, and the plurality of mounting feet 113 are arranged at intervals along the circumferential direction of the housing 110. The mounting feet 113 are provided with card slots 114, and the card slots 114 are located at one end of the mounting feet 113 facing away from the outside, and the card slots 114 penetrate through both ends of the mounting feet 113 along the axial direction. The seal 300 further includes a plurality of first damping portions 311, and the plurality of first damping portions 311 are connected to the first sealing rib 310 and are arranged at intervals along the circumferential direction of the first sealing rib 310. The number of the first damping portions 311 is the same as the number of the card slots 114, and the plurality of first damping portions 311 are respectively clamped in the corresponding plurality of card slots 114 to determine the relative positions of the seal 300 and the abutting portion 112, playing a positioning role. A plurality of mounting holes 221 are provided on the mounting portion 220, and the plurality of mounting holes 221 are arranged at intervals around the sink 115. The motor body 100 further includes a fastener (not shown in the figure), and the fastener passes through the first damping portion 311 and the mounting hole 221 to be fixedly connected to the mounting portion 220, so that the motor body 100 and the bracket 200 can be fixedly connected. For example, the fastener is a screw, and the screw passes through the first damping portion 311 and is threadedly connected to the mounting hole 221.

[0054] It can be understood that the first damping portion 311 has elasticity, and the fastener passes through the first damping portion 311. Therefore, the fastener and the mounting foot 113 are arranged at intervals, which can prevent the vibration generated during the operation of the motor from being transmitted to the bracket 200 through the fastener by the mounting foot 113, thereby reducing the vibration of the motor driving the bracket 200, reducing the noise during the operation of the motor, and improving the user experience.

[0055] Referring to Figure 2 and Figure 4 As shown, in the embodiment of the present utility model, a sink 115 is provided on an end wall of the mounting foot 113 along the axial direction, and the sink 115 is communicated with one end of the card slot 114. The first damping portion 311 includes a connecting column 312 and two damping pads 313, and damping pads 313 are connected to both ends of the connecting column 312. The connecting column 312 is clamped in the card slot 114, and one of the damping pads 313 is located in the sink 115, and the other damping pad 313 abuts against the end wall of the mounting groove 230 facing away from the sink 115. It can be understood that when the fastener is a screw, the head of the screw is located in the sink 115, preventing the head of the screw from protruding from the mounting foot 113, and a damping pad 313 is provided between the head of the screw and the bottom wall of the sink 115, which can prevent the screw from directly contacting the mounting foot 113, so as to reduce the situation that the vibration of the motor is transmitted to the bracket 200 through the screw. The damping pad 313 abutting against the end wall of the mounting groove 230 facing away from the sink 115 can prevent the mounting foot 113 from directly contacting the mounting portion 220, reducing the situation that the vibration of the motor is transmitted to the bracket 200 through the mounting foot 113, so as to reduce the noise during the operation of the motor.

[0056] Referring to Figure 4 As shown, in the embodiment of the present utility model, the first damping portion 311 and the first sealing rib 310 are integrally formed. For example, the first damping portion 311 can be a rubber part or a silica gel part, and is manufactured by injection molding. By integrally injecting the first damping portion 311 and the first sealing rib 310, the production steps of the seal 300 can be simplified, the production efficiency can be improved, and the connection between the first damping portion 311 and the first sealing rib 310 is stable and reliable, and it is not easy to loosen and fall off. No additional positioning is required during installation, and the assembly efficiency is high.

[0057] Referring to Figure 7 and Figure 8 As shown, in another embodiment of the present utility model, one of the positioning posts 314 or the positioning holes 116 is provided on the side of the first sealing rib 310 facing the abutting portion 112, and the other of the positioning posts 314 or the positioning holes 116 is provided on the side of the abutting portion 112 facing the first sealing rib 310. The positioning posts 314 and the positioning holes 116 are in positioning cooperation to determine the relative position between the first sealing rib 310 and the abutting portion 112, and improve the accuracy during assembly. For example, a plurality of positioning posts 314 are provided at intervals on the first sealing rib 310, and a plurality of positioning holes 116 are provided at intervals on the abutting portion 112. The plurality of positioning posts 314 and the plurality of positioning holes 116 are in one-to-one correspondence to improve the connection stability between the first sealing rib 310 and the abutting portion 112. Alternatively, a plurality of positioning holes 116 are provided at intervals on the first sealing rib 310, and a plurality of positioning posts 314 are provided at intervals on the abutting portion 112. Specifically, a suitable setting method is selected according to the actual situation.

[0058] Referring to Figure 9 and Figure 10 As shown, in another embodiment of the present utility model, a plurality of mounting feet 113 are provided on the outer side wall of the housing 110, and the plurality of mounting feet 113 are arranged at intervals along the circumferential direction of the housing 110. The mounting feet 113 are provided with card slots 114, and the card slots 114 are located at the end of the mounting feet 113 facing away from the outside, and the card slots 114 penetrate through both ends of the mounting feet 113 along the axial direction. The motor assembly 1000 further includes a plurality of second damping portions 330, and the plurality of second damping portions 330 are correspondingly clamped in the card slots 114. The first sealing rib 310 is provided with a positioning groove 315 for positioning the second damping portions 330. A plurality of mounting holes 221 are provided on the mounting portion 220, and the plurality of mounting holes 221 are arranged at intervals around the sinking groove 115. The motor body 100 further includes a fastening member (not shown in the figure), and the fastening member passes through the first damping portion 311 and the mounting holes 221 to be fixedly connected to the mounting portion 220, so that the motor body 100 and the bracket 200 can be fixedly connected. For example, the fastening member is a screw, and the screw passes through the second damping portion 330 and is threadedly connected to the mounting holes 221.

[0059] It can be understood that the second damping part 330 is elastic, and the fastener passes through the second damping part 330. Therefore, the fastener and the mounting foot 113 are spaced apart, which can prevent the vibration generated during the operation of the motor from being transmitted to the bracket 200 through the fastener by the mounting foot 113, thereby reducing the vibration of the motor driving the bracket 200, reducing the noise generated during the operation of the motor, and improving the user experience. It should be noted that the structure of the second damping part 330 is similar to that of the first damping part 311, and the structure and effect of the first damping part 311 can be referred to for understanding, and will not be specifically described here.

[0060] Refer to Figure 5 As shown, in an embodiment of the present invention, the motor body 100 further includes a rotor 140, a stator 130, and a rotating shaft 150. The rotor 140 and the stator 130 are both disposed in the cavity 111, and the rotating shaft 150 passes out of the cavity 111. The stator 130 is annular and fixedly connected to the wall surface of the cavity 111. The rotor 140 is located inside the stator 130 and is spaced apart from the stator 130. The rotating shaft 150 is fixedly connected to the rotor 140 and is rotatably connected to the housing 110. Through the cooperation of the stator 130 and the rotor 140, the rotating shaft 150 can be driven to rotate, thereby outputting torque.

[0061] An air conditioner according to an embodiment of the present invention includes the motor assembly 1000 of the above embodiment. In the air conditioner according to the embodiment of the present invention, the motor assembly 1000 of the above embodiment is adopted. The motor assembly 1000 is connected by setting the housing 110 and the end cover 120 of the motor body 100, and an abutting portion 112 is provided around the outer side wall of the housing 110. The bracket 200 is fixedly connected to the motor body 100. A groove 210 for accommodating the end cover 120 is recessed on one side of the bracket 200. The mounting portion 220 of the bracket 200 is disposed around the groove 210. An installation groove 230 is formed between the mounting portion 220 and the abutting portion 112. The first sealing rib 310 of the seal 300 is disposed in the installation groove 230 and at least seals a part of the installation groove 230 above the rotation axis of the motor body 100, which can effectively prevent water flow from entering the gap 121 between the end cover 120 and the housing 110 to improve the waterproof effect of the motor. At the same time, the first sealing rib 310 does not need to be disposed in the gap 121 between the end cover 120 and the housing 110, which has little impact on the production and manufacturing of the motor body 100. And the first sealing rib 310 is between the mounting portion 220 and the abutting portion 112, and can also play a damping effect, effectively reducing the occurrence of the vibration of the motor being transmitted to the bracket 200, thereby reducing the noise generated during the operation of the motor body 100 and improving the user experience. Therefore, while having a sealing effect, the first sealing rib 310 also plays a damping role, which can simplify the structure of the motor assembly 1000 and improve the assembly efficiency.

[0062] Since the air conditioner adopts all the technical solutions of the motor assembly 1000 in the above embodiment, it at least has all the beneficial effects brought by the technical solutions in the above embodiment, which will not be elaborated here.

[0063] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
