[0049] Embodiment 1

[0050] like Figures 1 to 5 As shown, this embodiment provides a direct drive motor, which can reasonably utilize the internal space of the clothing processing device, and is conducive to reducing the overall volume of the clothing processing device. The direct drive motor includes a stator 1 and a rotor 2.

[0051] Among them, see Figure 1 and Figure 3 The stator 1 is arranged on a fixed installation part of the clothing processing device, and the fixed installation part is located at one end of the delivery port 101 of the drum 10 of the clothing processing device, and the clothing can be taken in and out of the drum 10 through the delivery port 101. The rotor 2 is coaxially arranged in the stator 1 or outside the stator 1, and the rotor 2 is fixed on the drum 10 of the clothing processing device. The rotor 2 can drive the drum 10 to rotate under the action of the magnetic field generated by the stator 1.

[0052] Specifically, when the coil of the stator 1 of the direct drive motor is energized, the stator 1 generates a magnetic field, and the magnetic fields of the stator 1 and the rotor 2 interact to generate a rotation torque, so that the rotor 2 drives the drum 10 to rotate, thereby turning the clothes in the drum 10. The direct drive motor is composed of a stator 1 and a rotor 2.

[0053] Exemplarily, the stator 1 is an electromagnet wound with a coil, and the rotor 2 is a permanent magnet or an electromagnetic coil. When current passes through the coil of the stator 1, a magnetic field is generated. By adjusting the magnitude and direction of the current, the rotation speed and direction of the rotor 2 can be controlled, thereby controlling the speed and direction of rotation of the cylinder 10.

[0054] Since the fixed installation part of the clothing processing equipment is located at one end of the feeding port 101 close to the drum 10, the stator 1 is fixedly installed on the fixed installation part, and the rotor 2 is fixed on the drum 10, so that the direct drive motor can be placed in front to avoid the direct drive motor occupying the space on the rear side of the drum 10. In addition, since the rotor 2 is coaxially arranged outside the stator 1 or inside the stator 1, it will not occupy too much space on the front side of the drum 10, which is conducive to reducing the volume of the entire clothing processing equipment and realizing a thin design of the entire machine. Especially for a dryer, placing the direct drive motor in front can reserve sufficient space for arranging the drying fan 50 and the air duct on the rear side of the drum 10, thereby realizing reasonable use of the internal space of the clothing processing equipment.

[0055] Optionally, see Figure 1 and Figure 2 The fixed installation part includes a front support 20 of the clothing processing device, and the stator 1 is detachably installed on the front support 20. The stator 1 is directly fixed on the front support 20, and no additional components for installing the stator 1 are required, which can make full use of the existing structure of the clothing processing device and minimize the overall size of the clothing processing device. The detachable installation method is convenient for assembly and later maintenance of the direct-drive motor.

[0056] Optionally, the direct drive motor further comprises a fastener, see Figure 3 and Figure 4 A first connecting hole 203 and / or a connecting column 204 is provided on the front support 20, and a second connecting hole 11 corresponding to the first connecting hole 203 or the connecting column 204 is provided on the stator 1. The fastener passes through the second connecting hole 11 and is connected and fixed to the corresponding first connecting hole 203 or the connecting column 204, thereby realizing the detachable installation of the stator 1 and the front support 20.

[0057] Exemplarily, the fastener is a screw, the first connecting hole 203 is a threaded hole, the connecting column 204 is also provided with a threaded hole, and the second connecting hole 11 is a smooth hole. The stator 1 and the front support 20 can be fixed by passing the screw through the smooth hole and tightening it into the corresponding threaded hole.

[0058] In this embodiment, refer to Figure 4Since the side of the front support 20 facing the stator 1 is not a flat plane, a first connecting hole 203 and a connecting column 204 are provided on the front support 20 at the same time. The first connecting hole 203 is provided at the protruding portion, and the connecting column 204 is provided at the recessed portion, and the protruding surface of the connecting column 204 is flush with the plane of the protruding portion. In this way, the stator 1 can be more stably installed and fixed to the front support 20, thereby ensuring the coaxiality of the stator 1 and the rotor 2 and improving the driving stability of the direct drive motor.

[0059] Exemplarily, two first connecting holes 203 are provided on the front support 20, five connecting columns 204 are provided on the front support 20, and seven second connecting holes 11 are provided on the stator 1 at intervals in the circumferential direction. The seven second connecting holes 11 are arranged one-to-one corresponding to the two first connecting holes 203 and the five connecting columns 204, thereby improving the installation stability of the stator 1 on the front support 20.

[0060] In other embodiments, the number of the first connection holes 203 , the connection pillars 204 , and the second connection holes 11 may be adaptively increased or decreased according to actual needs and is not limited to the number listed in this embodiment.

[0061] In other embodiments, only connecting posts 204 corresponding to the second connecting holes 11 may be provided on the front support 20 , as long as the installation requirements of the stator 1 are met and the stator 1 and the front support 20 are securely fixed.

[0062] Optionally, see Figure 3 and Figure 5 The front end of the cylinder 10 is provided with a mounting ring 102, and the rotor 2 is fixedly sleeved on the mounting ring 102. The mounting ring 102 provides a mounting base for the rotor 2, so that the rotor 2 can cooperate with the stator 1 on the front support 20 to drive the cylinder 10 to rotate.

[0063] In this embodiment, the mounting ring 102 is fixed to the cylinder 10 by riveting, and the connection is firm. For example, the front end of the cylinder 10 is folded to form a U-shaped first flange, and the mounting ring 102 is folded to form a U-shaped second flange. The first flange and the second flange are engaged with each other, and the first flange and the second flange are riveted and fixed together by riveting, so that the mounting ring 102 and the cylinder 10 are installed and fixed.

[0064] In other embodiments, the mounting ring 102 and the cylinder 10 may be fixed by welding; or the mounting ring 102 and the cylinder 10 may be integrally formed, which can reduce the subsequent assembly process.

[0065] Optionally, the rotor 2 is interference fit or keyed with the mounting ring 102 to limit the rotor 2 circumferentially on the mounting ring 102, so that the rotor 2 can drive the cylinder 10 to rotate synchronously through the mounting ring 102. For example, a key can be provided on the mounting ring 102, and a keyway that matches the key can be provided on the rotor 2.

[0066] In other embodiments, the rotor 2 may also be bonded and fixed to the mounting ring 102 , as long as the rotor 2 and the mounting ring 102 can be firmly fixed to ensure that the rotor 2 can drive the cylinder 10 to rotate synchronously.

[0067] In this embodiment, the stator 1 is coaxially arranged outside the rotor 2. Figure 3 The mounting ring 102 includes a large diameter section and a small diameter section connected to each other. The large diameter section is connected and fixed to the cylinder 10. The diameter of the small diameter section is smaller than the diameter of the cylinder 10. The rotor 2 is sleeved and fixed on the small diameter section, and the stator 1 is coaxially sleeved outside the rotor 2.

[0068] In other embodiments, if the stator 1 is coaxially disposed in the rotor 2 , the diameter of the end of the mounting ring 102 away from the cylinder 10 may be set to be greater than or equal to the diameter of the cylinder 10 .

[0069] Optionally, see Figure 3 and Figure 4 The fixed mounting portion is provided with an annular sealing groove 201, a sealing member 202 is provided in the annular sealing groove 201, and the mounting ring 102 at least partially extends into the annular sealing groove 201 and is in sealing contact with the sealing member 202. The sealing member 202 can prevent the liquid in the cylinder 10 from reaching the rotor 2 and the stator 1, avoid the rotor 2 and the stator 1 from contacting the liquid, and ensure the normal operation of the direct drive motor; on the other hand, the sealing member 202 can also play a buffering role, so that the mounting ring 102 and the front support 20 are in flexible contact, thereby improving the rotation stability of the cylinder 10 and avoiding friction noise.

[0070] Further, see Figure 3 The end of the mounting ring 102 away from the cylinder 10 is folded to form an arc-shaped limiting flange 1021, and the limiting flange 1021 contacts the sealing member 202 to ensure sufficient contact area and good sealing effect.

[0071] In other optional embodiments, a fixed installation portion may be separately provided near the front support 20, and the rotor 2 of the direct drive motor may be correspondingly installed at the position of the drum 10 corresponding to the fixed installation portion, so that the direct drive motor can be placed in front without reserving a large space on the rear side of the drum 10, thereby achieving the purpose of thin design of the clothing processing equipment.

[0072] Embodiment 2

[0073] like Figure 1 and Figure 2As shown, this embodiment provides a clothing processing device, including a housing (not shown), a drum 10, and the direct drive motor as described in the first embodiment, the drum 10 and the direct drive motor are both located in the housing, and the direct drive motor is used to drive the drum 10 to rotate, so as to flip the clothing in the drum 10. Exemplarily, the clothing processing device can be a drum washing machine, a dryer, or a washer-dryer, etc. When the clothing processing device is a drum washing machine, the drum 10 is the inner drum of the drum washing machine; when the clothing processing device is a dryer, the drum 10 is the dryer drum of the dryer.

[0074] The clothing processing device using this direct-drive motor can avoid occupying the space on the rear side of the drum 10 due to the front placement of the direct-drive motor, and rationally utilize the internal space of the clothing processing device, which is conducive to reducing the volume of the entire clothing processing device, realizing a thin design of the entire machine, and providing users with a better user experience.

[0075] Embodiment 3

[0076] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, this embodiment provides a clothes processing device, wherein the clothes processing device includes a clothes dryer, the clothes dryer includes a bottom support 40 and a rear support 30, the fixed installation portion includes a front support 20, the front support 20 and the rear support 30 are respectively arranged at the front and rear ends of the bottom support 40, and the rear end of the drum 10 is rotatably connected to the rear support 30. That is, the front support 20, the rear support 30 and the bottom support 40 jointly support the drum 10 to ensure the rotation stability of the drum 10.

[0077] Further, see Figure 6 and Figure 7 A drying air duct 401 is provided on the bottom support 40, and an evaporator and a condenser 402 are sequentially provided in the drying air duct 401 along the air flow direction. A fan 50 is provided on the rear support 30, and the air inlet end of the drying air duct 401 is connected to the air outlet of the cylinder 10, and the air outlet end of the drying air duct 401 is connected to the air inlet end of the fan 50, and the air outlet end of the fan 50 is connected to the air inlet of the cylinder 10.

[0078] When the drying program is executed, the fan 50 is started, so that the humid air in the barrel 10 enters the drying air duct 401 through the air outlet of the barrel 10, and flows through the evaporator and the condenser 402 in sequence. The evaporator converts the humid air into dry cold air, and the condenser 402 converts the dry cold air into dry hot air. The fan 50 then passes the dry hot air into the barrel 10 through the air inlet of the barrel 10, so that the dry hot air contacts the wet clothes in the barrel 10, and the clothes are dried in this cycle.

[0079] Further, see Figure 2The air outlet of the drum 10 is located on the front support 20, and a lint filter 205 is provided at the air outlet. The lint filter 205 is used to filter the lint carried in the air flow to prevent the lint from clogging the drying air duct 401 and avoid excessive lint accumulation at the evaporator, thereby ensuring smooth airflow in the drying air duct 401, thereby improving the drying efficiency of the dryer and shortening the drying time.

[0080] Furthermore, a compressor 403 is provided on the bottom support 40 , one port of the compressor 403 is connected to the condenser 402 through a pipeline, and another port of the compressor 403 is connected to the evaporator through a pipeline. The compressor 403 is used to maintain the refrigerant circulating in the refrigeration system formed between the evaporator and the condenser 402 .

[0081] Optionally, see Figure 1 and Figure 6 The fan 50 includes a volute 501 and an impeller 502 disposed on the rear support 30. The volute 501 includes a first shell 5011 and a second shell 5012 connected to each other. The rear support 30 is provided with a receiving groove 301. The first shell 5011 and the receiving groove 301 are surrounded to form an installation cavity. The impeller 502 is rotatably installed in the installation cavity. The rotation of the impeller 502 forms a negative pressure in the first shell 5011, so that the air in the cylinder 10 is drawn out through the drying air duct 401, and the heated air is passed into the cylinder 10 through the air inlet on the rear side of the cylinder 10. Furthermore, a through hole is provided in the receiving groove 301, which is directly opposite to the drying air duct 401, so that the air flow can flow out of the drying air duct 401 more smoothly under the action of negative pressure, thereby ensuring the drying efficiency.

[0082] In this embodiment, the first housing 5011 and the second housing 5012 are integrally formed, which is convenient for processing and does not require assembly in the later stage. The outer edges of the first housing 5011 and the second housing 5012 are both provided with lugs, which can be fixed to the rear support 30 by fasteners such as screws. Exemplarily, the first housing 5011 is in the shape of a spiral volute 501, and the second housing 5012 is approximately rectangular.

[0083] In other embodiments, the first shell 5011 and the second shell 5012 may also be processed separately and then spliced ​​and assembled at a later stage.

[0084] Further, see Figure 7The second housing 5012 is provided with a guide member, which separates a first air duct 50121 and a second air duct 50122 in the second housing 5012. The rear support 30 is provided with a first vent 302 and a second vent 303 which are in communication with the barrel 10. The first air duct 50121 is opposite to and in communication with the first vent 302, and the second air duct 50122 is opposite to and in communication with the second vent 303. The provision of the guide member can separate the heated dry air into two streams which are respectively passed into the barrel 10, preventing the airflow from forming a vortex in the first housing 5011, improving the smoothness of the airflow, and ensuring the drying efficiency of the clothes dryer; at the same time, the existence of the first air duct 50121 and the second air duct 50122 can accelerate the airflow, speed up the airflow circulation speed, and further improve the drying efficiency.

[0085] Furthermore, a heating device 503 is provided at one end of the second shell 5012 away from the first shell 5011, and a third vent 304 connected to the barrel 10 is provided on the rear support 30, and the heating device 503 is directly opposite to the third vent 304. In this embodiment, the first vent 302 and the second vent 303 are located near the bottom of the barrel 10, and the two are arranged at intervals, and the third vent 304 is located near the top of the barrel 10. The three vents can separate the airflow entering the barrel 10, ensure the uniformity of the airflow entering the barrel 10, and ensure the drying effect of the dryer. By arranging the heating device 503 at the upper end of the second shell 5012, the air reaching the upper end of the second shell 5012 can be heated again to ensure the temperature of the air entering the barrel 10.

[0086] Optionally, see Figure 7 The guide member includes a guide plate 5013, and the guide plate 5013 is curved and extends along the flow direction of the airflow. The arc-shaped guide plate 5013 can reduce the resistance to the airflow, and at the same time can prevent the airflow from generating vortices in the first air duct 50121 and the second air duct 50122, thereby ensuring smoother airflow.

[0087] Embodiment 4

[0088] This embodiment provides a clothes processing device, which is different from the third embodiment in that:

[0089] Optionally, the guide member includes a guide block, and guide surfaces are provided on opposite sides of the guide block. For example, the guide block is approximately triangular, with the sharp corner of the triangle facing the impeller 502, and two adjacent hypotenuses are the above-mentioned guide surfaces to separate the airflow in the second housing 5012 into two streams.

[0090] Furthermore, the two guide surfaces can be designed to be arc-shaped surfaces to reduce the air flow resistance and ensure smooth air flow.
