[0035] A first aspect of this application provides a mounting structure for a dual-rotor motor, in combination with Figures 1 to 4 and Figures 7 to 8 As shown, in some embodiments, the mounting structure for the dual-rotor motor includes a mounting base 1000 and a dual-rotor motor 2000. Among them, the mounting base 1000 is provided with a first limiting portion 1001 and a second limiting portion 1002. The dual-rotor motor 2000 is mounted on the mounting base 1000. The dual-rotor motor 2000 includes a stator 2300, and the stator 2300 is provided with a third limiting portion 2310 and a fourth limiting portion 2320. When the stator 2300 rotates in a first direction, the third limiting portion 2310 moves accordingly and abuts against the first limiting portion 1001. When the stator 2300 rotates in a second direction, the fourth limiting portion 2320 moves accordingly and abuts against the second limiting portion 1002. The first direction is opposite to the second direction.
[0036] By providing a first limiting portion 1001 and a second limiting portion 1002 on the mounting base 1000, and a third limiting portion 2310 and a fourth limiting portion 2320 on the stator 2300 of the dual-rotor motor 2000, after the dual-rotor motor 2000 is mounted on the mounting base 1000, the third limiting portion 2310 cooperates with the first limiting portion 1001 to prevent the dual-rotor motor 2000 from rotating in a first direction (the first direction is clockwise when facing Figure 4 ), and the fourth limiting portion 2320 cooperates with the second limiting portion 1002 to prevent the dual-rotor motor 2000 from rotating in a second direction, where the first direction is opposite to the second direction (the second direction is counterclockwise when facing Figure 4 ). In this way, the rotation of the rotor is limited to prevent the stator 2300 from colliding with other components when the restraint on the stator 2300 fails.
[0037] Specifically, the dual-rotor motor 2000 includes a stator 2300 and two rotors. The two rotors are a first rotor 2100 and a second rotor 2200 respectively. The first rotor 2100 and the second rotor 2200 are the rotatable parts. In the dual-rotor motor 2000, the first rotor 2100 is disposed on one side of the stator 2300, and the second rotor 2200 is disposed on the other side of the stator 2300. The first rotor 2100 is configured to be rotatable relative to the stator 2300, and the second rotor 2200 is also configured to be rotatable relative to the stator 2300. It can be understood that the rotation of the first rotor 2100 and the rotation of the second rotor 2200 can be independent, or the rotation of the first rotor 2100 and the rotation of the second rotor 2200 can be synchronous. For example, when the first rotor 2100 rotates, the second rotor 2200 does not move, or when the first rotor 2100 does not move, the second rotor 2200 rotates, or the rotation speed of the first rotor 2100 is different from the rotation speed of the second rotor 2200 when rotating, or the rotation speed of the first rotor 2100 is the same as the rotation speed of the second rotor 2200 when rotating, or the rotation direction of the first rotor 2100 is different from the rotation direction of the second rotor 2200.
[0038] The stator 2300 is the stationary part. The stator 2300 can refer to the iron core, or it can refer to a module composed of the iron core and the housing, etc. The stator 2300 is used to generate a changing magnetic field to control the rotation of the first rotor 2100 and the second rotor 2200. For example, the stator 2300 has two parts, defined as the first part and the second part. The first part corresponds to the first rotor 2100 and is used to control the rotation of the first rotor 2100. The second part corresponds to the second rotor 2200 and is used to control the rotation of the second rotor 2200. The first part and the second part can be designed as a whole, or they can be a split structure connected and fixed together by connecting means. The first part includes the first winding, and the second part includes the second winding. When the first winding is energized, it generates a changing magnetic field acting on the first rotor 2100, thereby driving the first rotor 2100 to rotate. When the second winding is energized, it generates a changing magnetic field acting on the second rotor 2200, thereby driving the second rotor 2200 to rotate.
[0039] The mounting base 1000 is a component for mounting the dual-rotor motor 2000. The mounting base 1000 needs to be set to have a relatively high structural strength. The mounting base 1000 can be an integrally formed structure, or it can be a split component connected and fixed together by connecting means.
[0040] Taking the laundry treatment device 3000 as an example to illustrate the double-rotor motor mounting structure (the laundry treatment device 3000 includes the double-rotor motor mounting structure), the double-rotor motor 2000 further includes a support shaft 2800, a bushing 2400, a pulley 2500, a first support wheel 2600, and a second support wheel 2700. The support shaft 2800 passes through the first rotor 2100, the stator 2300, and the second rotor 2200. One end of the support shaft 2800 protrudes from the first rotor 2100 and is defined as the first end, and the other end of the support shaft 2800 protrudes from the second rotor 2200 and is defined as the second end. The first support wheel 2600 is used to support the first end, and the second support wheel 2700 is used to support the second end. The first support wheel 2600 is fixed to the mounting base 1000, and the second support wheel 2700 is fixed to the mounting base 1000. In this way, the double-rotor motor 2000 is mounted on the mounting base 1000. At this time, the stator 2300, the first rotor 2100, and the second rotor 2200 are suspended (the stator 2300 is arranged at intervals with the mounting base 1000, the first rotor 2100 is arranged at intervals with the mounting base 1000, and the second rotor 2200 is arranged at intervals with the mounting base 1000). The bushing 2400 is sleeved on the first end and is fixedly connected to the first rotor 2100. The first rotor 2100 can drive the bushing 2400 to rotate. The pulley 2500 is fixed to the stator 2300 and is configured to be rotatably arranged. A first transmission belt 3300 is connected between the bushing 2400 and the pulley 2500, and a second transmission belt 3400 is connected between the pulley 2500 and the drying drum 3100 of the laundry treatment device 3000. The first rotor 2100 drives the bushing 2400 to rotate, the bushing 2400 drives the pulley 2500 to rotate through the first transmission belt 3300, and the pulley 2500 drives the drying drum 3100 to rotate through the second transmission belt 3400. The second rotor 2200 can drive the support shaft 2800 to rotate. The blower wheel 3200 of the laundry treatment device 3000 is fixedly connected to the second end of the support shaft 2800. When the double-rotor motor 2000 is working, the first rotor 2100 drives the drying drum 3100 to rotate, the second rotor 2200 drives the blower wheel 3200 to rotate, and the blower wheel 3200 drives the air flow to be conveyed into the drying drum 3100. In this way, the drying of the clothes is realized.
[0041] It can be understood that since the pulley 2500 is connected and fixed to the stator 2300, a second transmission belt 3400 is connected between the pulley 2500 and the drying drum 3100, and the rotatable position of the drying drum 3100 is also relatively fixed. Therefore, the drying drum 3100 forms a certain constraint on the stator 2300 through the second transmission belt 3400. In addition, a spring 3500 is usually configured. One end of the spring 3500 is hung on the stator 2300 (directly or indirectly), and the other end is hooked to the mounting base 1000. By pulling the stator 2300 through the spring 3500, a certain constraint on the stator 2300 can also be formed. When the dual-rotor motor 2000 is working, if the second transmission belt 3400 and / or the spring 3500 are disconnected, the constraint effect on the stator 2300 fails, and the stator 2300 will rotate and collide with other components such as the electric control box 3700 or the drying drum 3100, and even damage the corresponding components (the electric control box 3700 or the drying drum 3100).
[0042] Therefore, in this embodiment, the mounting base 1000 is provided with a first limiting portion 1001 and a second limiting portion 1002, and the stator 2300 is provided with a third limiting portion 2310 and a fourth limiting portion 2320. When the stator 2300 rotates in the first direction, the third limiting portion 2310 moves with the stator 2300, and the third limiting portion 2310 abuts against the first limiting portion 1001. In this way, the first limiting portion 1001 blocks the third limiting portion 2310 from continuing to move with the stator 2300, thereby blocking the stator 2300 from continuing to rotate in the first direction and realizing the limit of the stator 2300 rotating in the first direction. When the stator 2300 rotates in the second direction, the fourth limiting portion 2320 moves with the stator 2300, and the fourth limiting portion 2320 abuts against the second limiting portion 1002. In this way, the second limiting portion 1002 blocks the fourth limiting portion 2320 from continuing to move with the stator 2300, thereby blocking the stator 2300 from continuing to rotate in the second direction and realizing the limit of the stator 2300 rotating in the second direction.
[0043] It can be understood that the abutment between the third limiting portion 2310 and the first limiting portion 1001 can be that the third limiting portion 2310 is in close contact with the first limiting portion 1001 before following the movement, and abuts against the first limiting portion 1001 at the moment of following the movement and is blocked by the first limiting portion 1001. It can also be that there is a small gap between the third limiting portion 2310 and the first limiting portion 1001 before following the movement, and the third limiting portion 2310 abuts against the first limiting portion 1001 after following the movement for a shorter path (determined by the size of the gap) and is blocked by the first limiting portion 1001, and the same is true for the cooperation between the fourth limiting portion 2320 and the second limiting portion 1002. For example, the first limiting portion 1001 and the third limiting portion 2310 are arranged alternately to have a gap, and the second limiting portion 1002 and the fourth limiting portion 2320 are arranged alternately to have a gap, so as to avoid collision between the first limiting portion 1001 and the third limiting portion 2310, and between the second limiting portion 1002 and the fourth limiting portion 2320 due to the operation vibration of the dual-rotor motor 2000, thereby avoiding the generation of abnormal noise.
[0044] Furthermore, the first direction and the second direction are designed to be opposite, thereby limiting the rotation of the stator 2300 and preventing the stator 2300 from colliding with other components or even damaging corresponding components (drying barrel 3100, electric control box 3700, etc.) when the stator 2300 rotates accidentally.
[0045] Combination Figures 3 to 6 As shown, in some embodiments, the mounting seat 1000 includes a bottom plate 1100 and a side plate 1200, and a clamping cavity 1400 is formed between the side plate 1200 and the bottom plate 1100. When the dual-rotor motor 2000 is installed on the mounting seat 1000, the stator 2300 is located in the clamping cavity 1400, and the stator 2300 is arranged above the bottom plate 1100, the bottom plate 1100 is provided with a first limiting portion 1001, and the side plate 1200 is provided with a second limiting portion 1002.
[0046] Specifically, the orientation in this article is based on the normal placement of the product. Taking the normal installation of the clothing processing device as an example, the user faces the clothing processing device 3000, the side of the clothing processing device 3000 facing the user is the front, the side away from the user is the back, the left hand corresponding to the user is the left, the right hand corresponding to the user is the right, the side close to the ground is the bottom, and the side away from the ground is the top. The formation of the clamping cavity 1400 provides space for the installation of the dual-rotor motor 2000, and the structure of the bottom plate 1100 and the side plate 1200 forms a preliminary protection for the stator 2300.
[0047] exist Figure 1In the structure shown, a part of the drying drum 3100 is located above the dual-rotor motor 2000, and the electronic control box 3700 is located on one side of the dual-rotor motor 2000 and corresponds to the side plate 1200. By providing a first limiting portion 1001 on the bottom plate 1100 and a second limiting portion 1002 on the side plate 1200, the rotation of the stator 2300 in the clamping cavity 1400 is restricted, preventing the stator 2300 from rotating and colliding with the drying drum 3100 and the electronic control box 3700.
[0048] Combined with Figure 4 and Figure 9 As shown, in some embodiments, a virtual plane 3800 is defined. The virtual plane 3800 is vertically arranged and passes through the rotation axis of the dual-rotor motor 2000. The third limiting portion 2310 is provided on one side of the virtual plane 3800, and the fourth limiting portion 2320 is provided on the other side of the virtual plane 3800.
[0049] Specifically, the virtual plane 3800 is perpendicular to the bottom plate 1100, thereby dividing the stator 2300 into two parts. The third limiting portion 2310 is provided on one part of the stator 2300, and the fourth limiting portion 2320 is provided on the other part of the stator 2300. It can be understood that since the third limiting portion 2310 cooperates with the first limiting portion 1001 and the fourth limiting portion 2320 cooperates with the second limiting portion 1002, the first limiting portion 1001 is located on one side of the virtual plane 3800, while the second limiting portion 1002 is located on the other side of the virtual plane 3800. By arranging the third limiting portion 2310 and the fourth limiting portion 2320 on opposite sides of the virtual plane 3800, the space of the clamping cavity 1400 is fully utilized, avoiding the influence on the structure layout caused by the third limiting portion 2310 and the fourth limiting portion 2320 being designed too close to each other, and also facilitating the reduction of manufacturing difficulty.
[0050] Furthermore, combined with Figure 9 As shown, in some embodiments, the included angle α between the line connecting the rotation center of the dual-rotor motor 2000 and the third limiting portion 2310 and the line connecting the rotation center of the dual-rotor motor 2000 and the fourth limiting portion 2320 satisfies α > 90°, for example, α is 91°, 95°, 100°, 110°, 120°, 130° or 140°. It can be understood that since the stator 2300 needs to be arranged in the clamping cavity 1400, the closer the stator 2300 is to the corner position of the clamping cavity 1400 (the intersection position of the side plate 1200 and the bottom plate 1100), the more the space of the clamping cavity 1400 is utilized. Therefore, in this embodiment, on the premise that the third limiting portion 2310 and the fourth limiting portion 2320 are arranged on opposite sides of the virtual plane 3800, by designing the included angle α to be greater than 90°, it is more beneficial for the stator 2300 to be close to the corner position of the clamping cavity 1400.
[0051] Combined with Figure 4 and Figure 9 As shown, in some embodiments, the lowest point of the third limiting portion 2310 is not lower than the lowest point of the stator 2300. For example, the lowest point of the third limiting portion 2310 may be higher than the lowest point of the stator 2300, or the lowest point of the third limiting portion 2310 and the lowest point of the stator 2300 may be at the same height. In this way, the stator 2300 can be made as close as possible to the bottom plate 1100 (while still maintaining an alternating arrangement), thereby maximizing the use of space.
[0052] Continuing to combine Figure 4 and Figure 9 As shown, in some embodiments, the fourth limiting portion 2320 is higher than the third limiting portion 2310, that is, the lowest point of the fourth limiting portion 2320 is higher than the highest point of the third limiting portion 2310. In this way, it is more beneficial to design the included angle α to be greater than 90°, thereby facilitating the stator 2300 to approach the corner position of the clamping cavity 1400 and making full use of the space of the clamping cavity 1400.
[0053] Continuing to combine Figure 4 and Figure 9 As shown, in some embodiments, when the stator 2300 rotates in the first direction, the third limiting portion 2310 is adapted to move downward, and when the stator 2300 rotates in the second direction, the fourth limiting portion 2320 is adapted to move downward. In this way, it is convenient to install the dual-rotor motor 2000 onto the mounting base 1000.
[0054] Specifically, when the stator 2300 rotates in the first direction, the third limiting portion 2310 moves downward to abut against the first limiting portion 1001. When the stator 2300 rotates in the second direction, the fourth limiting portion 2320 moves downward to abut against the second limiting portion 1002. Generally speaking, when installing the dual-rotor motor 2000 onto the mounting base 1000, first fix the mounting base 1000 on the support surface, and then control the dual-rotor motor 2000 to be installed onto the mounting base 1000 from top to bottom. The third limiting portion 2310 moves downward to abut against the first limiting portion 1001, and the fourth limiting portion 2320 moves downward to abut against the second limiting portion 1002. In this way, during the process of the dual-rotor being installed in place from top to bottom, it is not easily interfered with by the first limiting portion 1001 and the second limiting portion 1002, thus facilitating the installation of the dual-rotor motor 2000 in place.
[0055] Combined with Figure 7 and Figure 8As shown, in some embodiments, the third limiting portion 2310 protrudes radially from the surface of the stator 2300, and the fourth limiting portion 2320 protrudes radially from the surface of the stator 2300. The stator 2300 has a generally cylindrical outer surface to adapt to the structure of the rotor (the first rotor 2100 and the second rotor 2200). By protruding the third limiting portion 2310 and the fourth limiting portion 2320 from the surface of the stator 2300, interference in the cooperation between the stator 2300 and the rotor (the first rotor 2100 and the second rotor 2200) is avoided. And because the third limiting portion 2310 and the fourth limiting portion 2320 need to be abutted, the protrusion of the third limiting portion 2310 and the fourth limiting portion 2320 is more conducive to cooperating with the first limiting portion 1001 and the second limiting portion 1002.
[0056] A second aspect of the present application discloses a laundry treatment device 3000, which incorporates Figures 1 to 9 As shown, in some embodiments, the laundry treatment device 3000 includes the above-mentioned dual-rotor motor mounting structure. The dual-rotor motor mounting structure includes a mounting base 1000 and a dual-rotor motor 2000. Among them, the mounting base 1000 is provided with a first limiting portion 1001 and a second limiting portion 1002. The dual-rotor motor 2000 is mounted on the mounting base 1000. The dual-rotor motor 2000 includes a stator 2300, and the stator 2300 is provided with a third limiting portion 2310 and a fourth limiting portion 2320. When the stator 2300 rotates in the first direction, the third limiting portion 2310 moves accordingly and abuts against the first limiting portion 1001. When the stator 2300 rotates in the second direction, the fourth limiting portion 2320 moves accordingly and abuts against the second limiting portion 1002. The first direction and the second direction are opposite.
[0057] By providing the first limiting portion 1001 and the second limiting portion 1002 on the mounting base 1000, and providing the third limiting portion 2310 and the fourth limiting portion 2320 on the stator 2300 of the dual-rotor motor 2000, after the dual-rotor motor 2000 is mounted on the mounting base 1000, the third limiting portion 2310 cooperates with the first limiting portion 1001 to prevent the dual-rotor motor 2000 from rotating in the first direction, and the fourth limiting portion 2320 cooperates with the second limiting portion 1002 to prevent the dual-rotor motor 2000 from rotating in the second direction. The first direction and the second direction are opposite. In this way, the rotation of the rotor is limited to prevent the stator 2300 from colliding with other components when the constraint on the stator 2300 fails.
[0058] The dual-rotor motor 2000 further includes a support shaft 2800, a shaft sleeve 2400, a pulley 2500, a first support wheel 2600, and a second support wheel 2700. The support shaft 2800 passes through the first rotor 2100, the stator 2300, and the second rotor 2200. One end of the support shaft 2800 protrudes from the first rotor 2100 and is defined as the first end, and the other end of the support shaft 2800 protrudes from the second rotor 2200 and is defined as the second end. The first support wheel 2600 is used to support the first end, and the second support wheel 2700 is used to support the second end. The first support wheel 2600 is fixed to the mounting base 1000, and the second support wheel 2700 is fixed to the mounting base 1000. In this way, the dual-rotor motor 2000 is mounted on the mounting base 1000. At this time, the stator 2300, the first rotor 2100, and the second rotor 2200 are suspended (the stator 2300 is arranged at intervals with the mounting base 1000, the first rotor 2100 is arranged at intervals with the mounting base 1000, and the second rotor 2200 is arranged at intervals with the mounting base 1000). The shaft sleeve 2400 is sleeved on the first end and is fixedly connected to the first rotor 2100. The first rotor 2100 can drive the shaft sleeve 2400 to rotate. The pulley 2500 is fixed to the stator 2300 and is configured to be rotatably arranged. A first transmission belt 3300 is connected between the shaft sleeve 2400 and the pulley 2500, and a second transmission belt 3400 is connected between the pulley 2500 and the drying drum 3100 of the laundry treatment device 3000. The first rotor 2100 drives the shaft sleeve 2400 to rotate, the shaft sleeve 2400 drives the pulley 2500 to rotate through the first transmission belt 3300, and the pulley 2500 drives the drying drum 3100 to rotate through the second transmission belt 3400. The second rotor 2200 can drive the support shaft 2800 to rotate, and the air impeller 3200 of the laundry treatment device 3000 is fixedly connected to the second end of the support shaft 2800. When the dual-rotor motor 2000 is working, the first rotor 2100 drives the drying drum 3100 to rotate, the second rotor 2200 drives the air impeller 3200 to rotate, and the air impeller 3200 drives the air flow to be conveyed into the drying drum 3100, so as to realize the drying of the clothes.
[0059] It can be understood that since the pulley 2500 is connected and fixed to the stator 2300, a second transmission belt 3400 is connected between the pulley 2500 and the drying drum 3100, and the rotatable position of the drying drum 3100 is also relatively fixed. Therefore, the drying drum 3100 forms a certain constraint on the stator 2300 through the second transmission belt 3400. In addition, a spring 3500 is usually configured. One end of the spring 3500 is hung on the stator 2300 (directly or indirectly), and the other end is hooked to the mounting base 1000. By pulling the stator 2300 through the spring 3500, a certain constraint on the stator 2300 can also be formed. When the dual-rotor motor 2000 is working, if the second transmission belt 3400 and / or the spring 3500 is disconnected, the constraint effect on the stator 2300 fails, and the stator 2300 will rotate and collide with other components such as the electronic control box 3700 or the drying drum 3100, etc., and even damage the corresponding components (the electronic control box 3700 or the drying drum 3100).
[0060] To this end, in this embodiment, the mounting base 1000 is provided with a first limiting portion 1001 and a second limiting portion 1002, and the stator 2300 is provided with a third limiting portion 2310 and a fourth limiting portion 2320. When the stator 2300 rotates in the first direction, the third limiting portion 2310 moves with the stator 2300, and the third limiting portion 2310 abuts against the first limiting portion 1001. In this way, the first limiting portion 1001 blocks the third limiting portion 2310 from continuing to move with the stator 2300, thereby blocking the stator 2300 from continuing to rotate in the first direction, realizing the limit of the rotation of the stator 2300 in the first direction. When the stator 2300 rotates in the second direction, the fourth limiting portion 2320 moves with the stator 2300, and the fourth limiting portion 2320 abuts against the second limiting portion 1002. In this way, the second limiting portion 1002 blocks the fourth limiting portion 2320 from continuing to move with the stator 2300, thereby blocking the stator 2300 from continuing to rotate in the second direction, realizing the limit of the rotation of the stator 2300 in the second direction. It can be understood that the mutual abutment of the third limiting portion 2310 and the first limiting portion 1001 may be that the third limiting portion 2310 is in close contact with the first limiting portion 1001 before following the movement, and abuts against the first limiting portion 1001 at the moment of attempting to follow the movement and is blocked by the first limiting portion 1001. It may also be that there is a small gap between the third limiting portion 2310 and the first limiting portion 1001 before following the movement, and the third limiting portion 2310 follows a short path (determined according to the size of the gap) and then abuts against the first limiting portion 1001 and is blocked by the first limiting portion 1001. The same is true for the cooperation between the fourth limiting portion 2320 and the second limiting portion 1002. For example, the first limiting portion 1001 and the third limiting portion 2310 are arranged at intervals to have a gap, and the second limiting portion 1002 and the fourth limiting portion 2320 are arranged at intervals to have a gap, so as to avoid the collision between the first limiting portion 1001 and the third limiting portion 2310, and between the second limiting portion 1002 and the fourth limiting portion 2320 due to the operation vibration of the dual-rotor motor 2000, thereby avoiding the generation of abnormal noise. And, the first direction and the second direction are designed to be opposite, so as to realize the limitation of the rotation of the stator 2300, and avoid the collision between the stator 2300 and other components or even damage to the corresponding components (such as the drying drum 3100, the electronic control box 3700, etc.) when the stator 2300 rotates accidentally.
