[0004] Clothes-processing devices use a single motor rotor to drive the synchronous rotation of the drum and impeller to dry clothes. During the drying process, to prevent clothes from becoming tangled, the drum rotates forward for a period of time before reversing. This reversal of the impeller also causes a reduction in airflow, impacting the thermal system of the clothing-processing device and causing unstable operation. Related technologies include dual-rotor motors, which have two rotors that drive the drum and impeller separately, allowing for independent control without interfering with each other. However, current dual-rotor motors still require improvement.

[0041] In a first aspect of the present application, a motor 100 is proposed. As shown in Figures 1, 2 and 3, the motor 100 includes a stator 1300, a first rotor 1100, a second rotor 1200, a transmission shaft 2000, a first support structure 3100, a second support structure 3200 and a pulley 4200. The first rotor 1100 is arranged on one side of the stator 1300, and the second rotor 1200 is arranged on the other side of the stator 1300. The transmission shaft 2000 passes through the first rotor 1100, the stator 1300 and the second rotor 1200, and one end of the transmission shaft 2000 is exposed to the first rotor 1100, defined as the first end 2100, and the other end of the transmission shaft 2000 is exposed to the second rotor 1200, defined as the second end 2200.

[0042] The first supporting structure 3100 is used to support the first end 2100 , and the second supporting structure 3200 is used to support the second end 2200 . The motor 100 can be supported and installed by the first supporting structure 3100 and the second supporting structure 3200 .

[0043] The pulley 4200 is configured to be rotatable. The pulley 4200 is connected to the drum 5100 via the first transmission belt 4300, thereby driving the drum 5100 to rotate. The rotation of the pulley 4200 is achieved by the first rotor 1100. The first rotor 1100 drives the pulley 4200 to rotate, thereby causing the pulley 4200 to drive the drum 5100 to rotate via the first transmission belt 4300. It is understood that the first rotor 1100 can directly drive the pulley 4200 to rotate, or it can indirectly drive the pulley 4200 to rotate.

[0044] The pulley 4200 and the first support structure 3100 are disposed on the same side of the first rotor 1100 , and along the axial direction of the transmission shaft 2000 , the pulley 4200 is designed to be farther away from the first rotor 1100 than the first support structure 3100 .

[0045] The motor 100 forms a dual-rotor structure by setting up the first rotor 1100 and the second rotor 1200. The first rotor 1100 and the second rotor 1200 can be controlled separately to rotate relative to the stator 1300, so that they can drive the corresponding components (drum 5100, wind wheel 5200) separately without affecting each other; the first support structure 3100 and the second support structure 3200 are used to support the first end 2100 and the second end 2200 respectively, so that the installation of the motor 100 can be achieved; the first rotor 1100 can drive the pulley 4200 to rotate, and the pulley 4200 is farther away from the first rotor 1100 than the first support structure 3100, so that sufficient space can be left for the pulley 4200 to be directed toward the first rotor 1100 to install / avoid components such as the inverter 9000.

[0046] Specifically, the first rotor 1100, the stator 1300 and the second rotor 1200 cooperate with each other to make the motor 100 form a dual-rotor structure. The dual-rotor structure of the motor 100 means that the first rotor 1100 and the second rotor 1200 can be controlled separately without affecting each other. The second rotor 1200 can be stationary when the first rotor 1100 rotates, or the second rotor 1200 can be rotated when the first rotor 1100 is stationary. It can also be that the first rotor 1100 rotates forward and the second rotor 1200 rotates reversely, and the second rotor 1200 rotates forward when the first rotor 1100 rotates reversely.

[0047] It is understood that the stator 1300 is the stationary portion, while the first rotor 1100 and the second rotor 1200 are the rotatable portions. When the motor 100 is energized, the first rotor 1100 can rotate relative to the stator 1300, and the second rotor 1200 can rotate relative to the stator 1300. For example, the stator 1300 includes an iron core winding having a portion corresponding to the first rotor 1100 and a portion corresponding to the second rotor 1200. The first rotor 1100 and the second rotor 1200 each include a permanent magnet. When the stator 1300 is energized, the first rotor 1100 and / or the second rotor 1200 can be driven to rotate. Of course, the structures of the stator 1300, the first rotor 1100, and the second rotor 1200 are not limited to this. More examples of motors 100 with dual rotor structures can be found in related art, and are not further described here.

[0048] The first rotor 1100 is disposed on one side of the stator 1300 , and the second rotor 1200 is disposed on the other side of the stator 1300 . In this way, the motor 100 can drive corresponding components (the drum 5100 and the wind wheel 5200 ) on opposite sides, saving space. For example, the motor 100 is applied to a clothing processing device as an example for explanation (hereinafter the clothing processing device is used as an example for explanation, and the clothing processing device is, for example, a clothes dryer). The first rotor 1100 is used to drive the drum 5100 to rotate, and the second rotor 1200 is used to drive the wind wheel 5200 to rotate. When the clothing processing device dries clothes, the first rotor 1100 can drive the drum 5100 to rotate, and the second rotor 1200 can drive the wind wheel 5200 to rotate, thereby driving the air flow into the drum 5100, thereby achieving the drying of clothes. Since the rotation of the first rotor 1100 and the rotation of the second rotor 1200 are controlled separately and do not interfere with each other, when the first rotor 1100 drives the drum 5100 to rotate reversely, it does not affect the second rotor 1200 driving the wind wheel 5200 to rotate forward, and the airflow volume will not be reduced, which is more conducive to the drying of clothes and the stability of the thermal system (such as a heat pump system).

[0049] It is understandable that in the relevant technology, the drum 5100 and the wind wheel 5200 are driven simultaneously by the motor 100 (having only one rotor). During the process of drying clothes in the clothing processing device, the motor 100 needs to drive the drum 5100 to rotate forward and reverse to prevent the clothes from being entangled. Since the motor 100 drives the drum 5100 and the wind wheel 5200 at the same time, when the drum 5100 rotates forward and reverse, the wind wheel 5200 will also rotate forward and reverse accordingly. When the wind wheel 5200 reverses, the airflow volume will decrease. The decrease in airflow volume will cause the heat to increase instantaneously, which will have an impact on the temperature control and stable operation of the clothing processing device. For example, the clothing processing device heats the airflow through the operation of the heat pump system (that is, a heat pump type clothing processing device). When the wind wheel 5200 reverses, the decrease in airflow volume will cause the temperature of the heat pump system to increase instantaneously, which is not conducive to the stable operation of the clothing processing device. In this embodiment, by designing the motor 100 into a dual-rotor structure, the first rotor 1100 and the second rotor 1200 can be controlled separately and operate independently. The first rotor 1100 can realize forward rotation and reverse rotation, while the second rotor 1200 can always realize forward rotation. The first rotor 1100 and the second rotor 1200 do not interfere with each other. In this way, the second rotor 1200 can always rotate forward, and the airflow volume will not be reduced due to the reverse rotation of the first rotor 1100, thereby ensuring the stable operation of the clothing processing equipment.

[0050] It is worth noting that some related technologies also design two independent motors 100 to drive the drum 5100 and the wind wheel 5200 respectively, with one motor 100 corresponding to the drum 5100 and the other motor 100 corresponding to the wind wheel 5200. In this way, the drum 5100 and the wind wheel 5200 are controlled separately. However, the two motors 100 occupy a large space and require peripheral components such as inverters 9000 for each motor 100, which increases the cost. In this embodiment, by designing the motor 100 as a dual-rotor structure, it is more conducive to saving space and reducing costs.

[0051] Furthermore, the first rotor 1100 , the stator 1300 and the second rotor 1200 are supported by the setting of the transmission shaft 2000 , and the transmission shaft 2000 needs to pass through the first rotor 1100 , the stator 1300 and the second rotor 1200 , thereby supporting the first rotor 1100 , the stator 1300 and the second rotor 1200 .

[0052] There are various ways to support the first rotor 1100, the stator 1300, and the second rotor 1200 on the transmission shaft 2000. For example, the second rotor 1200 can be designed to be fixedly connected to the transmission shaft 2000. When the second rotor 1200 rotates, the second rotor 1200 needs to drive the transmission shaft 2000 to rotate, that is, the second rotor 1200 and the transmission shaft 2000 rotate synchronously. In other words, the connection between the second rotor 1200 and the transmission shaft 2000 needs to ensure that the two do not rotate relative to each other but rotate synchronously. There are various ways to connect the second rotor 1200 and the transmission shaft 2000. The second rotor 1200 and the transmission shaft 2000 can be connected by a slot and a pin to achieve mutual locking in the rotational direction to achieve synchronous rotation. Of course, other connection methods can also be used. Unlike the second rotor 1200, the first rotor 1100 is designed to rotate relative to the drive shaft 2000. This means that rotation of the drive shaft 2000 does not drive rotation of the first rotor 1100, and vice versa. This allows the second rotor 1200 to rotate the wind wheel 5200, while the first rotor 1100 drives the drum 5100, without interfering with each other. This example will be used below for illustration. Because the first rotor 1100 is rotatable relative to the drive shaft 2000, a bearing or other structure can be positioned between the first rotor 1100 and the drive shaft 2000 to provide support and reduce frictional resistance.

[0053] The two ends of the transmission shaft 2000 are defined as a first end 2100 and a second end 2200, respectively. The first end 2100 exposes the first rotor 1100, while the second end 2200 exposes the second rotor 1200. When the motor 100 is installed, the first end 2100 and the second end 2200 need to be supported to support the entire motor 100. This is achieved specifically by a first support structure 3100 and a second support structure 3200. The first support structure 3100 supports the first end 2100, while the second support structure 3200 supports the second end 2200. It will be appreciated that, using the example of the first support structure 3100 supporting the first end 2100, it is sufficient to ensure that the weight of the motor 100 can be applied to the first support structure 3100 through the first end 2100. That is, the first support structure 3100 can be in direct or indirect contact with the first end 2100, and the same applies to the second support structure 3200.

[0054] As mentioned above, if the transmission shaft 2000 needs to rotate along with the rotation of the second rotor 1200, then, in some cases, the transmission shaft 2000 is designed to be rotatable relative to the first support structure 3100 and the second support structure 3200, so that the first support structure 3100 and the second support structure 3200 do not need to rotate synchronously.

[0055] For example, as shown in Figures 3 and 4 , the first support structure 3100 is a first support wheel 3100, and the second support structure 3200 is a second support wheel 3200. When installing the motor 100, the first support wheel 3100 is placed at a corresponding position on the base 8000 of the clothing processing device and is limited in position, and the second support wheel 3200 is placed at a corresponding position on the base 8000 of the clothing processing device and is limited in position. The base 8000 supports the first support wheel 3100 and the second support wheel 3200, and the first rotor 1100, the stator 1300, and the second rotor 1200 are suspended in the air, thereby achieving installation support for the motor 100. When the motor 100 is operating, the first support wheel 3100 and the second support wheel 3200 are fixed, while the transmission shaft 2000 can rotate relative to the first support wheel 3100 and the second support wheel 3200.

[0056] The second rotor 1200 is used to drive the wind wheel 5200 to rotate. The second rotor 1200 and the wind wheel 5200 can be directly driven or indirectly driven. As mentioned above, the second rotor 1200 can drive the transmission shaft 2000 to rotate, so the wind wheel 5200 can be installed on the second end 2200. When the second rotor 1200 rotates, the second rotor 1200 drives the transmission shaft 2000 to rotate, and then drives the wind wheel 5200 to rotate, thereby realizing the transmission of airflow.

[0057] Different from the wind wheel 5200 , the driving of the drum 5100 is achieved through the cooperation between the first rotor 1100 and the pulley 4200 .

[0058] The pulley 4200 is configured to be rotatable. For example, the pulley 4200 is fixed to the stator 1300. It is understood that the pulley 4200 can be directly or indirectly disposed on the stator 1300. When the first rotor 1100 rotates, the first rotor 1100 drives the pulley 4200 to rotate. The first rotor 1100 can directly or indirectly drive the pulley 4200 to rotate. When the pulley 4200 rotates, the pulley 4200 drives the drum 5100 to rotate via the first transmission belt 4300.

[0059] It is understood that in the related art dual-rotor motor 100, components such as the inverter 9000 are positioned close to the motor 100 (the first rotor 1100, the stator 1300, and the second rotor 1200). If the pulley 4200 is closer to the first rotor 1100 than the first support structure 3100, the pulley 4200 may easily interfere with the inverter 9000 and other components. To this end, in this embodiment, the pulley 4200 and the first support structure 3100 are positioned on the same side of the first rotor 1100. The so-called same side defines a plane that passes through the first rotor 1100 and is perpendicular to the rotation axis of the first rotor 1100, and the pulley 4200 and the first support structure 3100 are positioned on the same side of the plane. In conjunction with the orientation shown in FIG3 , the pulley 4200 and the first support structure 3100 are both positioned in front of the first rotor 1100. Moreover, the pulley 4200 is farther away from the first rotor 1100 relative to the first support structure 3100, that is, the pulley 4200 and the first support structure 3100 are a certain distance apart along the axial direction of the transmission shaft 2000, so that the space on one side of the pulley 4200 is larger. Combined with the orientation shown in Figure 3, the first rotor 1100 is in front and the second rotor 1200 is in the back, that is to say, there is a larger space behind the pulley 4200 for placing / avoiding components such as the inverter 9000. Components such as the inverter 9000 can be arranged close to the motor 100 (the first rotor 1100, the stator 1300 and the second rotor 1200) without interfering with the pulley 4200, thereby more effectively utilizing the space of the base 8000 of the clothing processing device.

[0060] As shown in conjunction with Figures 3 and 4 , in some embodiments of the present application, the first rotor 1100 is designed to rotate relative to the transmission shaft 2000, that is, the rotation of the first rotor 1100 does not drive the transmission shaft 2000 to rotate, and the rotation of the transmission shaft 2000 does not drive the first rotor 1100 to rotate. The motor 100 also includes a sleeve 4100, which is sleeved onto the first end 2100 of the transmission shaft 2000 and is fixedly connected to the first rotor 1100 so that it can rotate with the rotation of the first rotor 1100. The sleeve 4100 also needs to be rotatable relative to the transmission shaft 2000 so that the rotation of the sleeve 4100 driven by the first rotor 1100 is not affected by the rotation of the transmission shaft 2000. At the same time, the first support structure 3100 needs to be sleeved with a sleeve 4100, that is, the sleeve 4100 passes through the first support structure 3100 from the first rotor 1100, so that the first support structure 3100 supports the sleeve 4100, thereby supporting the first end 2100 through the sleeve 4100, and then supporting the motor 100, so as to ensure that the pulley 4200 can be moved away from the first rotor 1100 relative to the first support structure 3100 through the matching of the second transmission belt 4400 and the sleeve 4100. The first rotor 1100 drives the pulley 4200 to rotate. It can be understood that since the first support structure 3100 is sleeved on the sleeve 4100, the space occupied along the axial direction of the transmission shaft 2000 can be reduced. If the first support structure 3100 and the sleeve 4100 are alternately arranged along the axial direction of the transmission shaft 2000, the space occupied will inevitably increase. In this embodiment, the sleeve 4100 is sleeved on the first support structure 3100, which is more conducive to the compactness of the base 8000.

[0061] The sleeve 4100 is mounted on the first rotor 1100 and is fixedly connected to the first rotor 1100. When the first rotor 1100 rotates, the first rotor 1100 drives the sleeve 4100 to rotate synchronously. A second transmission belt 4400 is used to connect the sleeve 4100 to the pulley 4200. When the first rotor 1100 rotates, the first rotor 1100 drives the sleeve 4100, which in turn drives the second transmission belt 4400. This in turn drives the pulley 4200 via the second transmission belt 4400, which in turn drives the drum 5100 via the first transmission belt 4300. The coordination of the sleeve 4100 and the pulley 4200 facilitates power transmission to the drum 5100. The diameters of the sleeve 4100 and the pulley 4200 can be adjusted to meet varying speed requirements.

[0062] For example, the second transmission belt 4400 surrounds the corresponding position of the sleeve 4100 and the corresponding position of the pulley 4200. When the sleeve 4100 rotates, the pulley 4200 can be driven to rotate through the second transmission belt 4400. The first transmission belt 4300 surrounds the corresponding position of the pulley 4200 and the corresponding position of the roller 5100. When the pulley rotates, the roller 5100 can be driven to rotate through the first transmission belt 4300.

[0063] More specifically, the sleeve 4100 has a first position 4110 and a second position 4120 arranged alternately, the first position 4110 is closer to the first rotor 1100, and the second position 4120 is farther away from the first rotor 1100 relative to the first position 4110, the first support structure 3100 is specifically sleeved on the first position 4110, and the second transmission belt 4400 is connected to the second position 4120, and the pulley 4200 corresponds to the second position 4120 in its radial direction.

[0064] It is understood that the sleeve 4100 needs to rotate with the first rotor 1100, and the first support structure 3100 mainly plays a supporting role. The first support structure 3100 does not need to rotate with the rotation of the sleeve 4100. To this end, the sleeve 4100 is designed to be rotatable relative to the first support structure 3100. That is, after the motor 100 is installed, the first support structure 3100 can remain stationary, while the sleeve 4100 can rotate with the rotation of the first rotor 1100. A structure similar to a bearing can be provided between the sleeve 4100 and the first support structure 3100 to reduce friction.

[0065] Since the sleeve 4100 needs to rotate relative to the drive shaft 2000, and the first support structure 3100 is sleeved on the sleeve 4100, the support for the first end 2100 is achieved through the sleeve 4100. For this reason, in combination with Figure 4, in some embodiments of the present application, the motor 100 also includes a bearing 4130, and the bearing 4130 is set on the sleeve 4100. The sleeve 4100 is sleeved on the drive shaft 2000 through the bearing 4130, that is, when the sleeve 4100 is sleeved on the drive shaft 2000, the bearing 4130 contacts the drive shaft 2000, thereby achieving support for the first end 2100 through the first support structure 3100. At the same time, through the setting of the bearing 4130, it can be ensured that the sleeve 4100 and the drive shaft 2000 can rotate relative to each other to reduce friction resistance.

[0066] As shown in Figure 4, in some embodiments of the present application, the motor 100 also includes a connecting shaft 4210, which is connected to the stator 1300, and the pulley 4200 is arranged on the connecting shaft 4210 and is rotatable relative to the connecting shaft 4210. Through the setting of the connecting shaft 4210, support is provided for the pulley 4200 to be further away from the first rotor 1100 relative to the first support structure 3100.

[0067] Specifically, in order to ensure that the pulley 4200 is further away from the first rotor 1100 relative to the first support structure 3100, in this embodiment, a connecting shaft 4210 is provided, one end of the connecting shaft 4210 is fixed on the stator 1300, and the other end of the connecting shaft 4210 is rotatably provided thereon, and the pulley 4200 and the connecting shaft 4210 form a cantilever structure, thereby ensuring that the pulley 4200 is further away from the first rotor 1100 relative to the first support structure 3100.

[0068] Furthermore, in combination with Figures 3 and 4, in some embodiments of the present application, the connecting shaft 4210 extends a certain distance along the axial direction of the transmission shaft 2000, thereby reducing the structural complexity of the connecting shaft 4210 and reducing the space occupied by the connecting shaft 4210.

[0069] Specifically, the connecting shaft 4210 extends along the axial direction of the transmission shaft 2000. That is, the connecting shaft 4210 is substantially straight along the axial direction of the transmission shaft 2000 and is approximately balanced with the transmission shaft 2000. This reduces the space occupied by the connecting shaft 4210 and simplifies the structure. One end of the connecting shaft 4210 is fixedly connected to the stator 1300 and extends a certain distance from the stator 1300 along the axial direction of the transmission shaft 2000. The wind wheel 5200 is rotatably mounted on the other end of the connecting shaft 4210.

[0070] As shown in Figure 3, in some embodiments of the present application, the motor 100 also includes a reinforcement portion 1310, which is arranged on the stator 1300, and the reinforcement portion 1310 extends from the stator 1300 to the radial direction of the first rotor 1100 for supporting the connecting shaft 4210, thereby enhancing the stability of the connecting shaft 4210.

[0071] As mentioned above, the connecting shaft 4210 and the pulley 4200 form a cantilever structure, which is unstable. Therefore, in this embodiment, a reinforcement portion 1310 is provided on the stator 1300, and the reinforcement portion 1310 extends from the stator 1300 to the radial direction of the first rotor 1100. In this way, while ensuring that the pulley 4200 is away from the first rotor 1100, the reinforcement portion 1310 can strengthen the support of the connecting shaft 4210, thereby ensuring the stability of the connecting shaft 4210 and the pulley 4200.

[0072] The reinforcement portion 1310 can be a part of the structure of the stator 1300 (such as being integrated with part of the stator 1300), or it can be fixed to the stator 1300 through connection means (such as being fixed to the stator 1300 by screw connection, welding, etc.), and can be designed according to actual conditions.

[0073] It is understood that there are various ways for the reinforcement portion 1310 to support the connecting shaft 4210, as long as an interaction is achieved between the reinforcement portion 1310 and the connecting shaft 4210, that is, when the connecting shaft 4210 deflects in a certain direction, the reinforcement portion 1310 can suppress the deflection of the connecting shaft 4210. With reference to Figures 3 and 4, in some embodiments of the present application, the connecting shaft 4210 passes through the reinforcement portion 1310. In this way, the reinforcement portion 1310 can form a constraint on the connecting shaft 4210 in the circumferential direction of the connecting shaft 4210, which not only facilitates the cooperation between the connecting shaft 4210 and the reinforcement portion 1310, but also facilitates the support of the connecting shaft 4210 by the reinforcement portion 1310.

[0074] As shown in FIG3 , in some embodiments of the present application, the connecting shaft 4210 is provided with a lug 6000 . The lug 6000 is provided between the pulley 4200 and the first rotor 1100 . The lug 6000 is used for hanging the spring 7000 so as to be pulled. It is understood that since the pulley 4200 is connected to the drum 5100 via the first transmission belt 4300, and since the motor 100 and the drum 5100 are two different components, to ensure that the first transmission belt 4300 is kept taut, a hook 6000 is provided on the connecting shaft 4210. The hook 6000 is suspended by a spring 7000 and pulled by the spring 7000, thereby tightening the first transmission belt 4300 and preventing it from loosening. For example, one end of the spring 7000 is suspended on the hook 6000, and the other end of the spring 7000 is connected to the base 8000 of the laundry processing device. When the spring 7000 pulls the hook 6000, it pulls the connecting shaft 4210. Since the pulley 4200 is further away from the first rotor 1100, there is more space behind the pulley 4200 (as shown in FIG. 3 ) to provide a hook, thereby avoiding interference between the components. It is understandable that the hanging ear 6000 can also be set on the reinforcement part 1310, as shown in Figure 5, which has similar technical effects and will not be repeated.

[0075] In some embodiments of the present application, the second support structure 3200 is sleeved onto the second end 2200 of the transmission shaft 2000 to support the second end 2200. Furthermore, by designing the transmission shaft 2000 to be rotatable relative to the second support structure 3200, the second support structure 3200 is prevented from rotating with the rotation of the transmission shaft 2000. The second support structure 3200 serves more as a support. It is understood that a structure similar to a bearing or the like can be designed between the second support structure 3200 and the transmission shaft 2000 to reduce friction.

[0076] The second aspect of the present application discloses a clothing processing device. As shown in Figures 1, 2 and 3, the clothing processing device includes a drum 5100, a wind wheel 5200 and a motor 100. The motor 100 includes a stator 1300, a first rotor 1100, a second rotor 1200, a transmission shaft 2000, a first support structure 3100, a second support structure 3200 and a pulley 4200. The first rotor 1100 is arranged on one side of the stator 1300, and the second rotor 1200 is arranged on the other side of the stator 1300. The transmission shaft 2000 passes through the first rotor 1100, the stator 1300 and the second rotor 1200, and one end of the transmission shaft 2000 is exposed to the first rotor 1100, defined as the first end 2100, and the other end of the transmission shaft 2000 is exposed to the second rotor 1200, defined as the second end 2200.

[0077] The first supporting structure 3100 is used to support the first end 2100 , and the second supporting structure 3200 is used to support the second end 2200 . The motor 100 can be supported and installed by the first supporting structure 3100 and the second supporting structure 3200 .

[0078] The pulley 4200 is configured to be rotatable. The pulley 4200 is connected to the drum 5100 via the first transmission belt 4300, thereby driving the drum 5100 to rotate. The rotation of the pulley 4200 is achieved by the first rotor 1100. The first rotor 1100 drives the pulley 4200 to rotate, thereby causing the pulley 4200 to drive the drum 5100 to rotate via the first transmission belt 4300. It is understood that the first rotor 1100 can directly drive the pulley 4200 to rotate, or it can indirectly drive the pulley 4200 to rotate.

[0079] The pulley 4200 and the first support structure 3100 are disposed on the same side of the first rotor 1100 , and along the axial direction of the transmission shaft 2000 , the pulley 4200 is designed to be farther away from the first rotor 1100 than the first support structure 3100 .

[0080] The motor 100 forms a dual-rotor structure by setting up the first rotor 1100 and the second rotor 1200. The first rotor 1100 and the second rotor 1200 can be controlled separately to rotate relative to the stator 1300, so that they can drive the corresponding components (drum 5100, wind wheel 5200) separately without affecting each other; the first support structure 3100 and the second support structure 3200 are used to support the first end 2100 and the second end 2200 respectively, so that the installation of the motor 100 can be achieved; the first rotor 1100 can drive the pulley 4200 to rotate, and the pulley 4200 is farther away from the first rotor 1100 than the first support structure 3100, so that sufficient space can be left for the pulley 4200 to be directed toward the first rotor 1100 to install / avoid components such as the inverter 9000.

[0081] For example, taking a heat pump type clothing processing device as an example, the drum 5100 of the clothing processing device is connected to the pulley 4200 through a first transmission belt 4300, and the wind wheel 5200 of the clothing processing device is installed on the second end 2200 of the transmission shaft 2000. The first rotor 1100 drives the drum 5100 to rotate, and the second rotor 1200 drives the wind wheel 5200 to rotate. They are controlled separately and do not interfere with each other.

[0082] It can be understood that the clothes processing device includes a motor 100, and the motor 100 of the clothes processing device adopts the technical solution of the above embodiment, so it has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0083] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
