Description

Technical Field

[0001] The embodiments of the present application relate to clothing processing technology, and more particularly to a clothes drying device. Background Art

[0002] A clothes dryer, such as a clothes dryer, is a household appliance used to quickly dry washed clothes by heating and ventilating them. Dryers are particularly important in humid or cold climates.

[0003] A clothes dryer includes an impeller and a drum. The impeller's rotation delivers air to the drum, drying the clothes inside. To conserve internal dryer space, the impeller and drum are driven by the same motor, resulting in synchronized movement. The impeller's alternating forward and reverse motion, which prevents clothes from tangling, also drives the impeller's alternating forward and reverse rotation.

[0004] However, when the impeller rotates reversely as the drum rotates, it fails to generate sufficient airflow, resulting in low drying efficiency and, in turn, severe energy consumption. While this energy consumption issue can be addressed by using two motors, each corresponding to the position of the impeller and the drum, allowing for separate control, this would likely take up more space inside the dryer, increasing the overall size of the dryer. This makes it difficult to balance internal dryer space with drying efficiency. Utility Model Content

[0005] The embodiments of the present application provide a clothes drying device that can solve the problem of balancing the internal space and drying efficiency of a clothes dryer.

[0006] In a first aspect, an embodiment of the present application provides a clothes drying device, comprising:

[0007] a cabinet having an interior space;

[0008] a drum, the drum being used to contain clothes; the drum being located in the internal space;

[0009] a wind impeller, the wind impeller being located in the internal space and being used to generate airflow, and the airflow can enter the drum;

[0010] A drive motor is used to drive the drum and the impeller to rotate, and the drive motor includes:

[0011] A first motor, the first motor comprising:

[0012] a first shell;

[0013] a first rotor located in the first housing;

[0014] a first stator, located in the first housing and not exposed to the outside of the first housing, and configured to provide a rotating magnetic field for the first rotor;

[0015] a first drive shaft fixedly connected to the first rotor, the first drive shaft having a first end extending outside the first housing, the first end being connected to the drum for driving the drum to rotate;

[0016] A second motor, the second motor comprising:

[0017] a second housing connected to an end surface of the first housing away from the first end of the first drive shaft, the second housing being detachably connected to the first housing;

[0018] a second rotor located in the second housing;

[0019] a second stator located in the second housing and not exposed to the outside of the second housing, the second stator being used to provide a rotating magnetic field for the second rotor;

[0020] A second drive shaft is fixedly connected to the second rotor, and the second drive shaft has a second end extending to the outside of the second shell. The second end of the second drive shaft is opposite to the first end of the first drive shaft, and the second end is connected to the impeller to drive the impeller to rotate, wherein the second drive shaft is spaced apart from the first drive shaft so that the second drive shaft and the first drive shaft are independent of each other.

[0021] In an embodiment of the present application, the drive motor includes a first motor and a second motor that move independently of each other. The first motor is provided with a first stator, a first rotor, and a first drive shaft. The first stator is used to provide a rotating magnetic field for the first rotor so that the first rotor and the first drive shaft rotate synchronously, thereby controlling the independent operation of the drum. The second motor is provided with a second stator, a second rotor, and a second drive shaft. The second stator is used to provide a rotating magnetic field for the second rotor so that the second rotor and the second drive shaft rotate synchronously, thereby controlling the independent operation of the impeller. This can provide sufficient airflow to the drum while avoiding tangling of clothes, thereby reducing the possibility of reduced drying efficiency and increased energy consumption due to low airflow.

[0022] Furthermore, the first stator in the embodiment of the present application is not exposed outside the first housing. This prevents coupling and mutual interference between the magnetic fields generated by the first and second stators, which could affect the stability of the driving force applied to the drum and impeller. The second rotor and second stator are also not exposed outside the second housing. Thus, by making it difficult for the first stator to be exposed outside the first housing, and the second stator to be exposed outside the second housing, the possibility of mutual interference between the magnetic fields generated by the first and second stators is reduced.

[0023] Furthermore, the first and second housings of the embodiments of the present application can be independent, split structures. Therefore, if the first or second motor fails, the first or second motor can be completely removed and maintained. Specifically, taking a failure of the first stator of the first motor as an example, during maintenance, the first motor can be removed from within the clothes dryer and then replaced outside the clothes dryer. Therefore, the maintenance process is not limited to the interior of the clothes dryer, facilitating maintenance operations and improving efficiency.

[0024] In some embodiments of the present application, the first stator is wound around at least a portion of the exterior of the first rotor and is not exposed outside the first housing.

[0025] In the embodiment of the present application, the first stator is wound around at least a portion of the first rotor, and can be used to generate a rotating magnetic field when the first stator is energized. The rotating magnetic field and the first rotor can interact to generate an electromagnetic force, thereby driving the first rotor to rotate.

[0026] In some embodiments of the present application, the second stator is wound around at least a portion of the exterior of the second rotor, and is not exposed outside the second housing.

[0027] In the embodiment of the present application, the second stator is wound around at least a portion of the second rotor, and can be used to generate a rotating magnetic field when the second stator is energized. The rotating magnetic field and the second rotor can interact to generate an electromagnetic force, thereby driving the second rotor to rotate.

[0028] In some embodiments of the present application, along the axial direction of the first drive shaft, the first drive shaft has a third end away from the first end, the third end is located in the first shell, and the third end is close to the inner wall of the first shell, and the first rotor is sleeved on the outside of the first drive shaft.

[0029] The first end of the first drive shaft in the embodiment of the present application can be connected to the roller to drive the roller to rotate. Since the second housing is connected to the end face of the first housing away from the first end of the first drive shaft, the second end of the first drive shaft can be located within the first housing and not exposed to the outside of the first housing. This can prevent the first drive shaft from extending into the interior of the second housing. On the one hand, this can prevent the first drive shaft from colliding with the second drive shaft, and on the other hand, it can reduce the possibility of the second stator and second rotor in the second housing interfering with the movement of the first drive shaft.

[0030] In some embodiments of the present application, along the axial direction of the second drive shaft, the second drive shaft has a fourth end away from the second end, the fourth end is located in the second shell, and the fourth end is close to the inner wall of the second shell, and the second rotor is sleeved on the outside of the second drive shaft.

[0031] In the embodiment of the present application, the second end of the second drive shaft can be connected to the impeller to drive the impeller. Since the second housing is connected to the end face of the first housing away from the first end of the first drive shaft, by arranging the fourth end of the second drive shaft to be located within the second housing and not exposed to the outside of the second housing, the second drive shaft is less likely to extend into the interior of the first housing. This can prevent the second drive shaft from colliding with the first drive shaft and reduce the possibility of the first stator and first rotor within the first housing interfering with the movement of the second drive shaft.

[0032] In some embodiments of the present application, the cabinet includes a back panel, which is located on the side of the drum facing away from the clothing inlet; the impeller is arranged on the side of the back panel facing away from the internal space, and the second drive shaft can be passed through the back panel to be connected to the impeller.

[0033] In the embodiment of the present application, by arranging the impeller on the side of the back plate facing away from the inner space, the drum and the impeller can be respectively located on both sides of the back plate. In this case, the airflow generated by the impeller can easily pass through the back plate into the drum.

[0034] In addition, compared to the related art, the motor for driving the drum to rotate and the motor for driving the impeller to rotate are respectively located on both sides of the back plate so that the motor can be close to the impeller. However, when the motor is arranged on the side of the back plate facing away from the impeller, it is easy to occupy the space where the airflow of the impeller flows, resulting in increased airflow resistance, thereby affecting the drying efficiency. Therefore, through the drive motor structure of the embodiment of the present application, and the drive motor being located in the internal space of the cabinet, the first motor and the second motor are both located in the internal space of the cabinet, so that the second motor for driving the impeller to rotate does not need to be arranged on the side of the back plate facing away from the internal space. In other words, the second motor can be less likely to occupy the space where the airflow of the impeller flows, thereby reducing the possibility of affecting the drying efficiency due to large airflow resistance.

[0035] In some embodiments of the present application, the clothes drying device further includes a rear air duct cover plate, which is arranged on the surface of the rear back plate facing away from the internal space, and the rear air duct cover plate is provided with a first guide space facing the rear back plate, the first guide space is connected to the internal space, and at least part of the impeller is located in the first guide space.

[0036] Because the motor driving the impeller in related art is located outside the rear panel, a recessed structure is required on the rear duct cover to secure the motor. This recessed structure increases airflow resistance, affecting drying efficiency. Furthermore, after the motor is secured to the recessed structure on the rear duct cover, a fixed end cap is also required on the side of the rear duct cover facing away from the rear panel to cover the motor.

[0037] Therefore, with the drive motor structure of the present embodiment and its fixation within the interior space of the clothes dryer, there is no need to machine a recessed structure on the rear duct cover to avoid the increased airflow resistance caused by the recessed structure, thus reducing manufacturing costs. Furthermore, there is no need for a fixed end cap, thus reducing the number of parts and lowering material, processing, assembly, and maintenance costs.

[0038] In some embodiments of the present application, the rear air duct cover is further provided with a second guide space connected to the first guide space, and the second guide space corresponds to the drum to guide the airflow generated by the impeller into the drum.

[0039] In the embodiment of the present application, the first guide space and the second guide space have the function of gathering and guiding the airflow. Through the first guide space and the second guide space, the airflow generated by the impeller can be fully guided into the drum to improve the drying efficiency.

[0040] In some embodiments of the present application, the clothes drying device further includes a base assembly, the base assembly is located in the interior space of the cabinet, and the drive motor is disposed in the base assembly;

[0041] The base assembly is connected to the back plate, and the surface of the base assembly facing the back plate is provided with an air guide channel opposite to the wind impeller. Along the axial direction of the second drive shaft, the air guide channel is recessed toward the internal space of the cabinet, and the air guide channel is connected to the first guide space.

[0042] In this embodiment of the present application, during the rotation of the impeller, the pressure differential formed within the internal space causes the airflow to flow through the drum and then into the heat pump system for drying and heating. The dry, high-temperature airflow then enters the air guide channel and, from there, into the first guide space, thereby achieving air circulation.

[0043] Specifically, the direction of airflow in the internal space of the cabinet can be as follows: the airflow generated by the impeller outlet can enter the second guide space from the first guide space. Since the second guide space corresponds to the drum. The airflow in the second guide space can enter the drum to absorb moisture from the clothes to be dried. After flowing out of the drum, the airflow can continue to flow and enter the heat pump system to form a dry high-temperature airflow through the heat pump system. The dry high-temperature airflow can flow to the air guide channel and enter the first guide space again through the air guide channel, thereby realizing circulation. It should be noted that since the air pressure at different positions in the internal space of the cabinet is different, it can be used to provide power for the airflow. Among them, the air pressure at the impeller outlet is the highest, the air pressure away from the impeller outlet gradually decreases, and the air inlet pressure of the impeller is the lowest. Therefore, the airflow can continue to flow in the direction of the impeller outlet with higher air pressure to realize airflow circulation.

[0044] In some embodiments of the present application, along the axial direction of the second drive shaft, the base assembly is provided with a first fixing member and a second fixing member facing each other at a position close to the back plate. The first drive shaft is rotatably connected to the first fixing member, and the second drive shaft is rotatably connected to the second fixing member.

[0045] The second fixing member is connected to the side wall of the air guiding channel, and the second driving shaft can pass through the air guiding channel to be connected to the wind impeller in the first guide space.

[0046] In the embodiment of the present application, the first fixing member and the second fixing member can be used to support the first drive shaft and the second drive shaft respectively. The space formed between the first fixing member and the second fixing member can be used to accommodate at least part of the drive motor.

[0047] In some embodiments of the present application, the clothes drying device further includes a control panel, which is disposed on the cabinet and close to the drive motor, and is electrically connected to the first motor and the second motor, and is used to drive the first motor and the second motor to operate.

[0048] In the embodiment of the present application, since the drive motor includes a first motor and a second motor connected to each other, the control board can be arranged close to the drive motor so that the connecting line between the control board and the first motor is not too long, and the connecting line between the control board and the second motor is not too long, thereby simplifying the wiring process.

[0080] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0084] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0085] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0086] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0087] A clothes dryer works by using high-temperature airflow to heat the clothes to be dried and remove the evaporated moisture, thereby achieving rapid drying of the clothes. Clothes dryers can dry clothes quickly and efficiently, regardless of weather or time of day, providing a better user experience.

[0088] Clothes dryers are generally classified into two types: wardrobe dryers and drum dryers. The clothes drying device of the embodiment of the present application may be a drum dryer.

[0089] A clothes dryer includes an impeller and a drum. The impeller rotates to deliver air to the drum. This rotation ensures that all parts of the clothes being dried are fully exposed to the high-temperature airflow, improving drying uniformity.

[0090] In the related art, the impeller and drum are driven by a single motor. The impeller and drum move synchronously. However, the applicant has discovered that constantly rotating the drum in the same direction can easily cause clothes inside the drum to become tangled. Therefore, the technical problem of clothes tangling can be solved by alternating the drum's forward and reverse rotation. Specifically, the drum can maintain a 1:1, full-time, alternating forward and reverse rotation cycle. For example, the motor drives the drum to rotate forward for 5 minutes, then reverse for 5 minutes, then forward again, and repeat this cycle.

[0091] However, the applicant found that during the synchronous movement of the impeller and the drum, the forward rotation of the impeller can provide airflow to the drum, while the airflow generated when the impeller rotates in the reverse direction is smaller, and thus the airflow delivered to the drum is also less, which easily leads to low drying efficiency and thus serious energy consumption problems.

[0092] To address the above technical issues, it is necessary to achieve independent movement of the impeller and the drum. This allows the drum to alternate between forward and reverse rotation to prevent tangling of dried clothes. Meanwhile, the impeller can maintain forward rotation to provide sufficient airflow to the drum. The impeller and drum's independent movement modes do not interfere with each other.

[0093] Therefore, two motors can be used to control the impeller and drum independently, achieving independent movement of the impeller and drum, thus resolving the issues of low drying efficiency and severe energy consumption. However, having two motors for the impeller and drum, respectively, tends to occupy a larger space inside the dryer, increasing the overall size of the dryer. This makes it difficult to balance internal space and drying efficiency.

[0094] Therefore, the present application provides a clothes drying device. In an embodiment of the present application, the driving motor for driving the drum and the impeller to move independently may include a first motor and a second motor connected to each other. The first motor and the second motor are each provided with a set of independent stator structures and rotor structures. Specifically, the stator structure in the first motor can provide a magnetic field for the rotor structure to drive the impeller to rotate, and make the impeller rotate in the same direction, so as to maintain sufficient airflow to the drum. Similarly, the stator structure and the rotor structure in the second motor cooperate with each other and can be used to drive the drum to rotate in the forward and reverse directions to avoid tangling of the clothes to be dried. The first motor and the second motor do not interfere with each other and are independent of each other.

[0095] Furthermore, the first and second motors are integrated into a single unit, making the layout more compact, saving internal space and making the clothes dryer thinner and lighter. The first and second motors can be assembled into a single unit and then installed within the clothes dryer, simplifying the assembly process and reducing installation costs.

[0096] In the embodiment of the present application, the first motor and the second motor are integrally structured, and the first motor and the second motor are close to and connected. Since the first motor is provided with a first stator capable of generating a magnetic field, and the second motor is provided with a second stator capable of generating a magnetic field, the magnetic field in the first motor and the magnetic field in the second motor are likely to interfere with each other. Therefore, by not exposing the first stator to the first housing, the first housing can be used to block at least part of the magnetic field from interfering with the magnetic field of the second motor. Similarly, by not exposing the second stator to the second housing, the second housing can be used to block at least part of the magnetic field from interfering with the magnetic field of the first motor, thereby reducing the possibility of mutual interference between the magnetic fields of the first and second motors.

[0097] The clothes drying device 100 provided in an embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0098] In some possible implementations, see Figure 1 and Figure 2 As shown, the clothes drying apparatus 100 may include a cabinet 140 .

[0099] The cabinet 140 has an internal space 140a, which can be used to accommodate internal structures such as the drum 110, the driving motor 130, and the heat pump system.

[0100] The clothes drying apparatus 100 may include a drum 110 .

[0101] The drum 110 can be used to accommodate clothes. For example, the clothes can be clothes to be dried. The rotation of the drum 110 can drive the clothes to rotate within the space of the drum 110, thereby increasing the contact area between the airflow and the clothes to be dried, thereby improving the drying efficiency.

[0102] In some possible implementations, see Figure 3 and Figure 4 As shown, clothes drying apparatus 100 may include an impeller 120. Rotation of impeller 120 can generate airflow. The airflow generated by impeller 120 can be transmitted to drum 110. Within drum 110, the airflow fully contacts the laundry to be dried. Because impeller 120 maintains the airflow, the airflow can remove moisture from the laundry to be dried, thereby drying the laundry.

[0103] In some examples, the interior of the clothes drying apparatus 100 can form an enclosed space. The airflow generated by the impeller 120 can circulate within the enclosed space. Specifically, the airflow pressure generated at the air outlet of the impeller 120 is the highest. The airflow pressure gradually decreases as one moves away from the air outlet of the impeller 120. Therefore, the airflow within the clothes drying apparatus 100 can flow along a specific air guide path due to a pressure differential. After the airflow within the drum 110 removes moisture from the clothes to be dried, it can flow to the exterior of the drum 110 due to the pressure differential.

[0104] In some examples, the clothes dryer 100 may also include a heat pump system for converting humid air into dry, hot air. The air absorbs moisture from the clothes to be dried, creating a humid airflow. This humid airflow, driven by a pressure differential, enters the heat pump system. The heat pump system then converts the humid airflow into a dry airflow. Then, due to the pressure differential created by the continuous rotation of the impeller 120, the dry airflow returns to the air inlet of the impeller 120 and reenters the drum 110, continuously drying the clothes.

[0105] In some examples, the impeller 120 may be, but is not limited to, a forward-curved centrifugal impeller, which has advantages such as high air volume, low noise, and high efficiency.

[0106] In some possible implementations, see Figure 3 and Figure 4 As shown, the clothes drying device 100 may further include a drive motor 130. The drive motor 130 of the embodiment of the present application may be used to drive the drum 110 and the impeller 120 to rotate. It should be noted that the drive motor 130 of the embodiment of the present application may enable the drum 110 and the impeller 120 to move independently.

[0107] In some possible implementations, see Figure 3 and Figure 4 As shown, the driving motor 130 may include a first motor 131 for driving the drum 110 to rotate.

[0108] In some possible implementations, see Figures 4 to 7 As shown, the first motor 131 may include a first rotor 1312 and a first stator 1313. The first stator 1313 may be used to provide a magnetic field for the first rotor 1312, so that when the first motor 131 is powered on, the magnetic field generated by the first stator 1313 may be used to drive the first rotor 1312 to rotate.

[0109] In some implementations, the first stator 1313 can be wrapped around the outside of the first rotor 1312. The first stator 1313 and the first rotor 1312 can be coaxially arranged. This coaxial arrangement of the first stator 1313 and the first rotor 1312 can achieve higher operating efficiency, thereby improving the operational reliability and rotational stability of the first motor 131 and facilitating reduced vibration and noise generated during operation of the first motor 131.

[0110] In some implementations, the first motor 131 may include a first housing 1311 . The first housing 1311 may be used to fix the first rotor 1312 and the first stator 1313 .

[0111] In some examples, the first rotor 1312 and the first stator 1313 may be completely located within the first housing 1311 . In other words, the first rotor 1312 and the first stator 1313 may not be easily exposed to the outside of the first housing 1311 .

[0112] In some possible implementations, see Figures 4 to 7 As shown, the drive motor 130 of the embodiment of the present application may further include a second motor 132. The second motor 132 may include a second rotor 1322 and a second stator 1323. The second stator 1323 may be used to provide a magnetic field for the second rotor 1322, so that when the second motor 132 is energized, the magnetic field generated by the second stator 1323 may be used to drive the second rotor 1322 to rotate.

[0113] In some implementations, the second stator 1323 can be enclosed outside the second rotor 1322. The second stator 1323 and the second rotor 1322 can be coaxially arranged. This coaxial arrangement of the second stator 1323 and the second rotor 1322 can achieve higher operating efficiency, thereby improving the operational reliability and rotational stability of the second motor 132 and facilitating reduced vibration and noise generated during operation of the second motor 132.

[0114] It should be noted that since the driving motor 130 of the embodiment of the present application includes a first motor 131 and a second motor 132, and the first motor 131 and the second motor 132 are provided with a first stator 1313 and a second stator 1323 that are independent of each other, therefore, by not exposing the first stator 1313 to the outside of the first shell 1311, it is possible to avoid coupling and mutual interference between the magnetic fields generated between the first stator 1313 and the second stator 1323, thereby affecting the stability of the driving force on the drum 110 and the impeller 120.

[0115] Similarly, in some examples, the second motor 132 may further include a second housing 1321. The second rotor 1322 and the second stator 1323 may also be completely located within the second housing 1321. In other words, the second rotor 1322 and the second stator 1323 may be less likely to be exposed outside the second housing 1321. By preventing the first stator 1313 from being exposed outside the first housing 1311, the second stator 1323 is also less likely to be exposed outside the second housing 1321, thereby reducing the possibility of interference between the magnetic fields generated by the first stator 1313 and the second stator 1323.

[0116] Therefore, the driving motor 130 of the embodiment of the present application can be a motor with dual stators, dual rotors and dual shells.

[0117] The first housing 1311 is provided with a cavity for accommodating the first stator 1313 and the first rotor 1312. The second housing 1321 is provided with a cavity for accommodating the second stator 1323 and the second rotor 1322.

[0118] In some embodiments, the first motor 131 may further include a first drive shaft 1314 for connecting to the drum 110. The first drive shaft 1314 is fixedly connected to the first rotor 1312. Therefore, when the first motor 131 is energized, the magnetic field generated by the first stator 1313 can drive the first rotor 1312 to rotate and drive the first drive shaft 1314 to move synchronously, thereby driving the drum 110 to rotate via the first drive shaft 1314.

[0119] In some implementations, the first driving shaft 1314 may have a first end 1314a extending outside the first housing 1311. The first end 1314a may be connected to the drum 110 to drive the drum 110 to rotate.

[0120] In some possible implementations, see Figures 4 to 7As shown, the second motor 132 may further include a second drive shaft 1324 for driving the impeller 120 to rotate. The second drive shaft 1324 is fixedly connected to the second rotor 1322. Therefore, when the second motor 132 is energized, the magnetic field generated by the second stator 1323 can drive the second rotor 1322 to rotate and drive the second drive shaft 1324 to move synchronously, thereby driving the drum 110 to rotate via the second drive shaft 1324.

[0121] In some embodiments, the second drive shaft 1324 may have a second end 1324a extending outside the second housing 1321. The second end 1324a may be connected to the impeller 120. The second end 1324a of the second drive shaft 1324 is opposite to the first end 1314a of the first drive shaft 1314.

[0122] In some implementations, the first motor 131 and the second motor 132 of the embodiment of the present application can be arranged side by side and connected along the axial direction of the first drive shaft 1314. The connection between the first motor 131 and the second motor 132 can make the overall structure of the drive motor 130 compact, which is beneficial for saving the internal space 140a of the drying device 100 and facilitating a thinner design of the clothes dryer.

[0123] It should be noted that the first shell 1311 and the second shell 1321 of the embodiment of the present application can be independent split structures. Therefore, when the first motor 131 or the second motor 132 fails, the first motor 131 or the second motor 132 can be disassembled as a whole and maintained. Specifically, taking the failure of the first stator 1313 of the first motor 131 as an example, during maintenance, the first motor 131 can be removed from the drying device 100, and then the first stator 1313 can be replaced outside the drying device 100. Therefore, the maintenance process is not limited to the internal space 140a of the drying device 100, which can facilitate maintenance operations and improve maintenance efficiency. After the replacement of the first stator 1313 is completed, the first motor 131 can be installed back to its original position as a whole.

[0124] In some implementations, the first housing 1311 and the second housing 1321 may be detachably connected, which means that the first housing 1311 and the second housing 1321 can be separated without being damaged.

[0125] In some examples, the first shell 1311 and the second shell 1321 can be fixedly connected by, but not limited to, threads, fasteners, etc.

[0126] In some examples, the longitudinal cross-section of the first housing 1311 and the second housing 1321 may be, but is not limited to, square, circular, etc. The longitudinal cross-section may refer to a plane perpendicular to the first driving shaft 1314 .

[0127] In some examples, along the axial direction of the first driving shaft 1314 , the orthographic projection of the outer contour of the first shell 1311 and the orthographic projection of the outer contour of the second shell 1321 may coincide with each other.

[0128] For some examples, see Figure 2 、 Figure 8 and Figure 9 As shown, the clothes drying device 100 may further include a belt transmission mechanism 200. When the second motor 132 is started, the drum 110 may be driven to rotate via the belt transmission mechanism 200.

[0129] For example, the belt drive mechanism 200 may include a first transmission belt 210, a second transmission belt 220, a first pulley 230, a second pulley 240, a third pulley 250, and a fourth pulley 260. The first pulley 230 may be disposed on the first drive shaft 1314 to move synchronously therewith. The first transmission belt 210 is sleeved over the first pulley 230 and the second pulley 240. Therefore, when the first motor 131 is in operation, the first drive shaft 1314 can drive the first pulley 230 to rotate. The first transmission belt 210 can transmit force to the first pulley 230 to drive the second pulley 240 to rotate. The third pulley 250 may be disposed on the second belt path. The rotation of the second pulley 240 can drive the third pulley 250 to rotate. The fourth pulley 260 may be sleeved over the exterior of the drum 110. The second transmission belt 220 may be disposed outside the third pulley 250 and the fourth pulley 260 . Therefore, when the third pulley 250 rotates, force may be transmitted through the second transmission belt 220 to drive the drum 110 to rotate through the fourth pulley 260 .

[0130] In some examples, the first pulley 230 and the second pulley 240 can serve as a driving pulley and a driven pulley, respectively, of a first-stage transmission. The first-stage transmission ratio can be 1 / 2.6.

[0131] For example, the diameter of the first pulley 230 may be 25 mm, and the diameter of the second pulley 240 may be 62.5 mm.

[0132] In some examples, the third pulley 250 and the fourth pulley 260 can serve as the driving pulley and the driven pulley of a two-stage transmission, respectively. The secondary transmission ratio can be 1 / 20.5.

[0133] For example, the diameter of the third pulley 250 may be 28 mm, and the diameter of the fourth pulley 260 may be 580 mm.

[0134] In some examples, the total transmission ratio of the belt transmission mechanism 200 in the embodiment of the present application may be between 1.51 and 1.54.

[0135] In the embodiment of the present application, the drive motor 130 can be a fixed-frequency motor or a variable-frequency motor, without specific limitation.

[0136] In some examples, when the drive motor 130 is a fixed-frequency motor, the theoretical limit speed of the second drive shaft 1324 in the first-stage transmission is 50 Hz*60s=3000 rpm, which can be met in actual measurement at 2700 rpm-2800 rpm.

[0137] In some examples, the rotation speed of the drum 110 is between 50 rpm and 53 rpm. When the rotation speed of the drum 110 is lower than 50 rpm, the centrifugal force is too low, and the clothes in the drum 110 may not be shaken out. When the rotation speed of the drum 110 is higher than 53 rpm, the centrifugal force is too high, and the clothes in the drum 110 may stick to the inner wall of the drum 110, thereby affecting the drying effect.

[0138] For some examples, see Figure 5 As shown, the belt transmission mechanism 200 may further include a connecting shaft 133 for fixing the second pulley 240. The connecting shaft 133 may be provided on at least one of the first housing 1311 and the second housing 1321 of the driving motor 130.

[0139] For example, the drive structure may include a cantilever. One end of the cantilever may be disposed on the second housing 1321, and the other end of the cantilever may be provided with a connecting shaft 133. Because the connecting shaft 133 and the first drive shaft 1314 are both disposed on the second housing 1321, the connecting shaft 133 and the first drive shaft 1314 can be relatively stable, thereby maintaining the stability of the belt drive mechanism 200 during transmission.

[0140] In some examples, the embodiments of the present application do not limit the types and models of the first motor 131 and the second motor 132. For example, the power of the first motor 131 used to drive the drum 110 can be greater than the power of the second motor 132 used to drive the impeller 120. Alternatively, the power of the first motor 131 and the power of the second motor 132 can be the same.

[0141] In some possible implementations, see Figures 4 to 7 As shown, the first stator 1313 can be wound around at least a portion of the outside of the first rotor 1312 .

[0142] In the embodiment of the present application, the first stator 1313 is wound around at least a portion of the first rotor 1312. When the first stator 1313 is energized, it can be used to generate a rotating magnetic field. The rotating magnetic field and the first rotor 1312 can interact to generate an electromagnetic force, thereby driving the first rotor 1312 to rotate.

[0143] In some examples, the first stator 1313 can be wound around the outside of the first rotor 1312, and the first rotor 1312 can be wound around the outside of the first drive shaft 1314. The first rotor 1312 and the first drive shaft 1314 are relatively fixed and can move synchronously.

[0144] In some examples, the first stator 1313 may include a plurality of stator cores, which may be distributed in a ring shape and fixed to the inner wall of the first housing 1311 .

[0145] In some possible implementations, see Figures 4 to 7 As shown, the second stator 1323 can be wound around at least a portion of the outside of the second rotor 1322 .

[0146] In the embodiment of the present application, the second stator 1323 is wound around at least a portion of the exterior of the second rotor 1322. When the second stator 1323 is energized, it can be used to generate a rotating magnetic field. The rotating magnetic field and the second rotor 1322 can interact to generate an electromagnetic force, thereby driving the second rotor 1322 to rotate.

[0147] In some examples, the second stator 1323 can be wound around the outside of the second rotor 1322, and the second rotor 1322 can be wound around the outside of the first drive shaft 1314. The second rotor 1322 and the second drive shaft 1324 are relatively fixed and can move synchronously.

[0148] In some possible implementations, see Figure 7 As shown, along the axial direction of the first drive shaft 1314, the first drive shaft 1314 has a third end 1314b away from the first end 1314a. The third end 1314b can be located within the first housing 1311, and the third end 1314b is close to the inner wall of the first housing 1311. The first rotor 1312 can be sleeved on the outside of the first drive shaft 1314.

[0149] The first end 1314a of the first drive shaft 1314 in the embodiment of the present application can be connected to the drum 110 to drive the drum 110 to rotate. Since the second housing 1321 is connected to the end surface of the first housing 1311 away from the first end 1314a of the first drive shaft 1314, the second end 1324a of the first drive shaft 1314 can be located inside the first housing 1311 and not exposed outside the first housing 1311. This makes it difficult for the first drive shaft 1314 to extend into the interior of the second housing 1321. On the one hand, this can prevent the first drive shaft 1314 from colliding with the second drive shaft 1324, and on the other hand, it can reduce the possibility of the second stator 1323 and the second rotor 1322 in the second housing 1321 interfering with the movement of the first drive shaft 1314.

[0150] In some possible implementations, see Figure 7 As shown, along the axial direction of the second drive shaft 1324, the second drive shaft 1324 has a fourth end 1324b away from the second end 1324a, the fourth end 1324b is located in the second shell 1321, and the fourth end 1324b is close to the inner wall of the second shell 1321, and the second rotor 1322 is sleeved on the outside of the second drive shaft 1324.

[0151] In the embodiment of the present application, the second end 1324a of the second drive shaft 1324 can be used to connect to the impeller 120 to drive the impeller 120. Since the second housing 1321 is connected to the end surface of the first housing 1311 away from the first end 1314a of the first drive shaft 1314, the fourth end 1324b of the second drive shaft 1324 is located within the second housing 1321 and is not exposed outside the second housing 1321. This prevents the second drive shaft 1324 from extending into the interior of the first housing 1311. On the one hand, this prevents the second drive shaft 1324 from colliding with the first drive shaft 1314, and on the other hand, it reduces the possibility of the first stator 1313 and the first rotor 1312 within the first housing 1311 interfering with the movement of the second drive shaft 1324.

[0152] In some examples, the third end 1314 b of the first drive shaft 1314 may be fixed to the first housing 1311 via a bearing 135 . The fourth end 1324 b of the second drive shaft 1324 may also be fixed to the upper cover of the second housing 1321 via a bearing 135 .

[0153] In some examples, concave spaces may be respectively provided on the opposite side walls of the first shell 1311 and the second shell 1321 for accommodating and fixing the bearing 135 .

[0154] In some possible implementations, see Figure 3As shown, the clothes drying device 100 may include a cabinet 140. The cabinet 140 has an inner space 140a for accommodating the drum 110 and the driving motor 130. During operation of the clothes drying device 100, the inner space 140a may be in a sealed environment.

[0155] In some possible implementations, see Figure 8 and Figure 10 As shown, the cabinet 140 may include a back panel 141. The back panel 141 is located on the side of the drum 110 facing away from the laundry inlet. The impeller 120 may be disposed on the side of the back panel 141 facing away from the interior space 140a. The second drive shaft 1324 may be disposed through the back panel 141 to connect to the impeller 120.

[0156] The front of the drum 110 is open. The front of the drum 110 can communicate with the laundry inlet of the clothes drying apparatus 100. The back of the drum 110 can be provided with a plurality of ventilation holes. The airflow generated by the impeller 120 can enter the drum 110 through the plurality of ventilation holes. The back of the drum 110 is located adjacent to the rear panel 141.

[0157] In the embodiment of the present application, by arranging the impeller 120 on the side of the back plate 141 facing away from the internal space 140a, the drum 110 and the impeller 120 can be respectively located on both sides of the back plate 141. In this case, the airflow generated by the impeller 120 can easily pass through the back plate 141 and enter the drum 110.

[0158] Furthermore, compared to the related art, in which the motors for driving the drum 110 and the impeller 120 are located on either side of the back plate 141, allowing the motors to be closer to the impeller 120, placing the motors on the side of the back plate 141 facing away from the impeller 120 can easily occupy the airflow space of the impeller 120, resulting in increased airflow resistance, which in turn affects drying efficiency. Therefore, by configuring the drive motor 130 in the embodiment of the present application, and by positioning the drive motor 130 in the interior space 140a of the cabinet 140, with both the first motor 131 and the second motor 132 located in the interior space 140a of the cabinet 140, the second motor 132, which drives the impeller 120, can be positioned without having to be on the side of the back plate 141 facing away from the interior space 140a. In other words, the second motor 132 is less likely to occupy the airflow space of the impeller 120, thereby reducing the likelihood of high airflow resistance affecting drying efficiency.

[0159] In some possible implementations, see Figure 8 and Figure 10As shown, the clothes drying apparatus 100 may further include a rear air duct cover plate 150. The rear air duct cover plate 150 may be disposed on a surface of the rear back plate 141 facing away from the interior space 140a. The rear air duct cover plate 150 may define a first guide space 150a facing the rear back plate 141. The first guide space 150a communicates with the interior space 140a. At least a portion of the impeller 120 is located in the first guide space 150a.

[0160] In an embodiment of the present application, the airflow generated by the impeller 120 can flow in the space between the rear back plate 141 and the rear air duct cover plate 150, and the airflow can be guided to the space corresponding to the drum 110 through the first guide space 150a of the rear air duct cover plate 150, so that the airflow can be introduced into the drum 110.

[0161] Furthermore, it should be noted that in the related art, the motor driving the impeller 120 is located outside the rear panel 141. Therefore, a recessed structure is required on the rear duct cover 150 to secure the motor. This recessed structure increases airflow resistance, thus affecting drying efficiency. Furthermore, after the motor is secured to the recessed structure of the rear duct cover 150, a fixed end cap is also required on the side of the rear duct cover 150 facing away from the rear panel 141 to cover the motor.

[0162] Therefore, the structure of the drive motor 130 in the embodiment of the present application, and its fixation within the interior space 140a of the clothes drying apparatus 100, eliminates the need for a recessed structure in the rear air duct cover 150, thereby preventing the increased airflow resistance caused by the recessed structure and reducing manufacturing costs. Furthermore, the need for a fixed end cap is eliminated, thereby reducing the number of parts and lowering material, manufacturing, assembly, and maintenance costs.

[0163] In some possible implementations, see Figure 8 and Figure 10 As shown, the rear air duct cover 150 may further include a second guide space 150 b communicating with the first guide space 150 a. The second guide space 150 b corresponds to the drum 110 to guide the airflow generated by the impeller 120 into the drum 110.

[0164] In this embodiment of the present application, the airflow generated by impeller 120 can first enter first guide space 150a. Because first guide space 150a is adjacent to and connected to second guide space 150b, the airflow can enter second guide space 150b under the influence of first guide space 150a. Second guide space 150b can prevent the airflow from dispersing outward and can guide the internal airflow of second guide space 150b into drum 110.

[0165] The first guide space 150a and the second guide space 150b have the function of gathering and guiding the airflow. Through the first guide space 150a and the second guide space 150b, the airflow generated by the impeller 120 can be fully guided into the drum 110 to improve the drying efficiency.

[0166] In some possible implementations, see Figure 8 and Figure 10 As shown, the clothes drying device 100 may further include a base assembly 160 . The base assembly 160 may be located in the inner space 140 a of the cabinet 140 . The driving motor 130 may be disposed on the base assembly 160 .

[0167] The base assembly 160 of the embodiment of the present application can be used to fix the drive motor 130 , the heat pump system, etc. The drum 110 can be located above the base assembly 160 .

[0168] In some possible implementations, see Figure 4 and Figure 10 As shown, the base assembly 160 is connected to the rear panel 141. A surface of the base assembly 160 facing the rear panel 141 may be provided with an air guide channel 160a opposite the impeller 120. Along the axial direction of the second drive shaft 1324, the air guide channel 160a is recessed toward the interior space 140a of the cabinet 140 and communicates with the first guide space 150a.

[0169] In the embodiment of the present application, during the rotation of the impeller 120, the pressure differential formed in the internal space 140a causes the airflow to flow through the drum 110 and then into the heat pump system for drying and heating. At this point, the dry, high-temperature airflow can enter the air guide channel 160a and then enter the first guide space 150a, thereby achieving air circulation.

[0170] Specifically, the airflow direction within the interior space 140a of the cabinet 140 can be as follows: the airflow generated by the air outlet of the impeller 120 can flow from the first guide space 150a to the second guide space 150b. Since the second guide space 150b corresponds to the drum 110, the airflow from the second guide space 150b can enter the drum 110 to absorb moisture from the laundry to be dried. After exiting the drum 110, the airflow can continue to flow and enter the heat pump system, where it forms a dry, high-temperature airflow. The dry, high-temperature airflow can flow to the air guide channel 160a and re-enter the first guide space 150a through the air guide channel 160a, thus completing the circulation. It should be noted that the different air pressures at different locations within the interior space 140a of the cabinet 140 can be used to provide power for the airflow. The air pressure is highest at the air outlet of the impeller 120, and gradually decreases away from the air outlet, reaching the lowest air pressure at the air inlet of the impeller 120. Therefore, the air flow can continuously flow toward the air outlet of the impeller 120 where the air pressure is higher, so as to realize air circulation.

[0171] For some examples, see Figure 10 As shown, the base assembly 160 may include an upper base 163 and a lower base 164. The upper base 163 and the lower base 164 each have a recessed space facing the interior space 140a on one side near the back panel 141. The upper base 163 and the lower base 164 are opposed to each other so that their respective recessed spaces communicate with each other, thereby forming an air guide channel 160a.

[0172] In some examples, the first fixing member 161 and the second fixing member 162 may be located on the lower base 164 .

[0173] In some possible implementations, see Figure 4 、 Figure 9 and Figure 10 As shown, along the axial direction of the second drive shaft 1324, the base assembly 160 is provided with a first fixing member 161 and a second fixing member 162, which are opposed to each other, near the rear panel 141. The first drive shaft 1314 is rotatably connected to the first fixing member 161. The second drive shaft 1324 is rotatably connected to the second fixing member 162. The second fixing member 162 is connected to the side wall of the air guide channel 160a. The second drive shaft 1324 can pass through the air guide channel 160a to connect to the impeller 120 within the first guide space 150a.

[0174] In the embodiment of the present application, the first fixing member 161 and the second fixing member 162 can be used to respectively support the first driving shaft 1314 and the second driving shaft 1324. The space formed between the first fixing member 161 and the second fixing member 162 can be used to accommodate at least part of the driving motor 130.

[0175] In some examples, the first drive shaft 1314 can be rotatably connected to the first fixing member 161 via a bearing 135 . The second drive shaft 1324 can also be rotatably connected to the second fixing member 162 via a bearing 135 .

[0176] In some examples, the bearing 135 can be sleeved on the outer wall of the first drive shaft 1314, and the bearing 135 can be fixed to the first fixing member 161 via a first fixing sleeve. The outer wall of the second drive shaft 1324 can also be provided with a bearing 135, and the bearing 135 can be fixed to the second fixing member 162 via a second fixing sleeve.

[0177] In some possible implementations, see Figure 11 As shown, the clothes drying device 100 may further include a control panel 170. The control panel 170 may be disposed on the cabinet 140 and close to the drive motor 130. The control panel 170 is electrically connected to the first motor 131 and the second motor 132. The control panel 170 is used to drive the first motor 131 and the second motor 132 to operate.

[0178] In the embodiment of the present application, since the drive motor 130 includes a first motor 131 and a second motor 132 connected to each other, the control board 170 can be arranged close to the drive motor 130 so that the connecting line between the control board 170 and the first motor 131 is not too long, and the connecting line between the control board 170 and the second motor 132 is not too long, thereby simplifying the wiring process.

[0179] It should be noted that, since the first stator 1313 of the first motor 131 and the second stator 1323 of the second motor 132 are independent of each other, the first rotor 1312 of the first motor 131 and the second rotor 1322 of the second motor 132 are also independent of each other, and the internal circuits of the first motor 131 and the second motor 132 are also independent of each other, a terminal 134 can be extended from each of the first housing 1311 of the first motor 131 and the second housing 1321 of the second motor 132. The terminal 134 can be used to connect to the control board 170.

[0180] In some examples, the driving motor 130 may further be provided with a terminal support 180 for supporting the connection terminal 134 . The terminal support 180 may be provided on at least one of the first housing 1311 and the second housing 1321 .

[0181] In some examples, when the terminal 134 is fixed to the terminal bracket 180 , the docking port of the terminal 134 may face downward to reduce the possibility of condensation forming on the wiring harness and flowing into the terminal 134 , causing a short circuit.

[0182] In some examples, the connection terminals 134 extending from the first motor 131 and the second motor 132 may be of different colors or shapes for differentiation, thereby reducing the possibility of incorrect insertion.

[0183] In some examples, since the control board 170 is electrically connected to the first motor 131 and the second motor 132 , the control board 170 may have a function of controlling the first motor 131 and the second motor 132 .
