[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "upper", "lower", "axial", "radial", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] In the description of the present invention, if described as "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0043] In the description of the present invention, it should be noted that the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0044] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0045] The vibration noise of the driving motor of the drum washing machine depends largely on the sealing performance of the motor against vibration noise. Generally, the motor usually includes a stator, a rotor, a front cover and a rear cover. The front and rear covers are assembled with the stator, and the front and rear covers are supported with the rotor. Since there is an assembly gap between the front and rear covers and the stator, noise is easily transmitted from the gap; and when there are many assembly parts, resonance is easily excited, resulting in increased noise. At the same time, as the number of assembly parts increases, the cost of the whole machine will also increase.

[0046] To solve the above problems, refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a motor 1000 suitable for a washing machine, a clothes dryer or other washing equipment. The motor 1000 of a drum washing machine is taken as an example for specific description below.

[0047] Reference Figure 1 and Figure 3 As shown, the motor 1000 of the embodiment of the present invention includes a stator 100, a rotor 200 and an end cover 300, wherein the stator 100 includes a stator core 110 and a plastic-encapsulated shell 120, and the plastic-encapsulated shell 120 is encapsulated on the stator core 110 through a plastic-encapsulation process, so that the stator core 110 and the plastic-encapsulated shell 120 form an integrated structure. In the embodiment, the stator 100 is also called a plastic-encapsulated stator. The rotor 200 is rotatably connected to the stator 100, and an open port 121 is provided at the front end of the plastic shell 120. The stator core 110 is annular, and the port 121 is connected to the inner cavity of the stator core 110. The rotor 200 can be assembled into the stator core 110 through the port 121; the end cover 300 covers the port 121, and the end cover 300 is connected to the plastic shell 120. The end cover 300 can be understood as the front end cover 300 of the motor 1000, and the front end of the rotor 200 is supported by the front end cover 300.

[0048] Reference Figure 3 As shown, the rotor 200 includes a rotor core 210 and a rotating shaft 220, wherein the rotating shaft 220 is disposed on the rotor core 210, wherein the front end of the rotating shaft 220 passes through the front end cover 300 to form a driving end 221, and the front end cover 300 is connected to the plastic package housing 120 by bolts 700. A front bearing 222 is installed on the front end cover 300, and the front end of the rotating shaft 220 is supported by the front bearing 222.

[0049] It should be noted that, in some embodiments, a rear end cover (not shown in the drawings) may be provided at the rear end of the plastic shell 120, and the plastic shell 120 is plastic-wrapped on the rear end cover so that the rear end cover and the plastic shell 120 are integrally formed, and a rear bearing 223 is installed on the rear end cover, and the rear end of the rotating shaft 220 is supported by the rear bearing 223, so that both ends of the rotor 200 are supported, so that the rotor 200 can stably operate in the stator 100.

[0050] Reference Figure 1 , Figure 3 and Figure 4 As shown, the motor 1000 further includes an electric control board 500, and a mounting structure 400 is provided at the rear end of the plastic-encapsulated housing 120, and the mounting structure 400 is used to accommodate the electric control board 500. It can be understood that, since the plastic-encapsulated housing 120 is formed on the rotor core 210 by injection molding, in the embodiment, the mounting structure 400 and the plastic-encapsulated housing 120 are integrally injection-molded, so that the assembly structure of the electric control board 500 and the rotor 200 can be simplified, the number of assembly parts can be reduced, and the assembly is easier.

[0051] In the related art, the electric control board of the motor is installed in a separate electric control box, and then the electric control box is installed on the motor, that is, the electric control box and the motor are separate structures, and the electric control box and the motor need to be fixedly connected by additional parts, and there is an assembly gap between the electric control box and the motor, which is not conducive to noise reduction. In the embodiment of the present invention, since the mounting structure 400 and the plastic package shell 120 are an integrated structure, the assembly gap is reduced, and the electric control box and corresponding assembly parts can be reduced, the assembly is simpler, and the motor 1000 is not easy to excite resonance, effectively reducing vibration noise, and at the same time helping to reduce the cost of the motor 1000.

[0052] It should be noted that the mounting structure 400 in the embodiment can play the role of an electric control box, can protect the electric control board 500, and can also be a bracket, a fixing platform, or other structures for fixing the electric control board 500. It can be understood that since the mounting structure 400 is formed at the rear end of the plastic package shell 120, when the rear end cover is assembled, the mounting structure 400 can cover the rear end cover, so that the rear end of the plastic package shell 120 forms a closed structure, which can reduce the assembly gap at the rear end of the motor 1000, make the sealing of the motor 1000 better, thereby reducing the noise from being transmitted outward through the assembly gap, and playing a role in noise reduction.

[0053] Of course, in some embodiments, since the mounting structure 400 is formed at the rear end of the stator core 110, the rear end of the stator core 110 forms a closed structure, so that the rear bearing 223 can also be directly installed on the side of the mounting structure 400 away from the electric control board 500. For example, a bearing chamber is formed on the side of the mounting structure 400 facing the stator core 110, and the bearing chamber is integrally formed with the mounting structure 400, and the rear bearing 223 is installed in the bearing chamber. In this way, the rear end cover component can be reduced and the structure can be further simplified.

[0054] It can be understood that the embodiment adopts a structure in which the mounting structure 400 and the stator 100 are integrally formed, which not only reduces the number of assembly parts of the motor 1000 as a whole, but also reduces the assembly gap, making it less likely for the motor 1000 to excite resonance, thereby reducing the generation of resonance and helping to reduce vibration noise.

[0055] It can be understood that in the embodiment of the present invention, the stator 100 also includes a winding, the winding is wound on the stator core 110, the electronic control board 500 is electrically connected to the winding, and the motor 1000 is connected to the circuit of the washing machine through the electronic control board 500, so as to realize power supply, signal transmission and other functions for the motor 1000, thereby controlling the operation of the motor 1000.

[0056] Considering that the temperature rise of the motor 1000 is mainly reflected in the temperature rise of the stator 100 winding, since there is an assembly gap between the assembly parts, the air in the assembly gap is a thermal resistance. In the case where there are many assembly parts and assembly gaps, it is not conducive to the heat dissipation of the stator 100 winding. The assembly gap will reduce the heat dissipation effect, which is not conducive to the stable operation of the motor 1000. By adopting the above structure, the embodiment of the present invention can reduce the number of assembly parts and the assembly gap, thereby reducing the air thermal resistance, and the heat can be transferred to the mounting structure 400 for heat dissipation, which is conducive to accelerating the heat dissipation of the winding, thereby improving the heat dissipation effect and facilitating the stable operation of the motor 1000.

[0057] It should be noted that the material used for the plastic shell 120 of the embodiment is bulk molding compound (BMC), which has lower cost than the shell of the motor using aluminum or other materials in the related art. The stator core 110, the plastic shell 120 and the mounting structure 400 can be easily integrated into an integrated structure through the plastic sealing process, which is easy to process and has a stable and reliable structure, effectively reducing the number of assembly parts of the motor 1000 and further reducing the cost of the entire machine.

[0058] Reference Figure 1 As shown, the end cover 300 can be connected to the plastic housing 120 by bolts 700. Specifically, a through hole arranged along the axial direction of the stator 100 is formed on the plastic housing 120. The bolts 700 pass through the end cover 300 and are fixedly connected to the plastic housing 120, so that the end cover 300 can be fixed. In the embodiment, the end cover 300 is fixed by three bolts 700, so that the end cover 300 is assembled stably and firmly. Of course, this is only an example, and the number of bolts 700 is not limited to three, but can also be four, five or more. The connecting member is not limited to the bolts 700, and can also be fixed by rivets or other methods, which are selected according to actual requirements.

[0059] Reference Figure 3 and Figure 4As shown, in some embodiments, the mounting structure 400 includes a box body 410, which is formed at the rear end of the plastic-encapsulated housing 120, and the box body 410 is roughly rectangular. Since the box body 410 and the plastic-encapsulated housing 120 are integrally formed, the electric control board 500 can be directly installed in the box body 410. Compared with the structure in which the electric control box and the motor 1000 are separated, it is not necessary to install the electric control box on the motor 1000 after the electric control board 500 is installed, which simplifies the assembly structure and improves the assembly efficiency. Moreover, there is no gap between the box body 410 and the stator 100, so as to achieve the purpose of reducing the assembly gap. The specific size of the box body 410 can be set according to the size of the electric control board 500, so that the electric control board 500 can be accommodated in the box body 410, which can protect the electric control board 500.

[0060] It can be understood that the box body 410 is formed as a whole with the plastic shell 120, and the box body 410 protrudes from the rear end of the plastic shell 120 in the direction away from the stator 100. The box body 410 is made of plastic. The electric control board 500 can be fixedly connected to the box body 410 by means of screws, snap connections, etc., so that the electric control board 500 is fixedly connected to the motor 1000. For example, the bottom wall of the box body 410 can be integrally formed with a screw hole, and the screws are passed through the electric control board 500 and fixedly connected to the screw hole, so that the electric control board 500 can be quickly fixed.

[0061] Of course, this is only an example, and the shape of the box body 410 is not limited to a rectangle, and can be a circle, a square, or other shapes.

[0062] In addition, since the electric control board 500 needs to be connected to the winding, the winding needs to be electrically connected to the electric control board 500 through the conductive structure through the box body 410. Specifically, the winding is wound on the stator core 110, and the lead wire of the winding is connected to the conductive sheet 413. Taking the three-phase winding as an example, each phase winding is welded to the conductive sheet 413, and the stator core 110, the winding and the conductive sheet 413 are plastic-sealed together through a plastic sealing process, and then the conductive sheet 413 is connected to the electric control board 500. The conductive sheet 413 is a conductive metal sheet, so that the electric control board 500 can be electrically connected to the winding, and the structure is stable and reliable.

[0063] Combination Figure 5 It can be understood that, considering that the conductive sheet 413 needs to be connected to the electric control board 500, after the stator 100 and the box body 410 are injection molded, a slot 412 is formed on the bottom wall of the box body 410, and the conductive sheet 413 is exposed in the slot 412. The electric control board 500 can be connected to the conductive sheet 413 by plugging. For example, the electric control board 500 is provided with a plug connector that matches the slot 412, and the conductive sheet 413 can be provided with two, three or more, which is specifically set according to the application requirements.

[0064] In some embodiments, in order to improve the connection stability between the electric control board 500 and the conductive sheet 413, after the electric control board 500 is inserted into the slot 412, the electric control board 500 and the conductive sheet 413 can be fixed by welding to ensure that the electric control board 500 and the conductive sheet 413 can maintain communication and are not easily loosened.

[0065] Continue to refer to Figure 4 and Figure 5 As shown, the box body 410 includes a surrounding edge 411, which protrudes from the rear end surface of the plastic shell 120 and is surrounded to form a rectangular frame. It can be understood that since the box body 410 and the plastic shell 120 are integrally formed, and the box body 410 is formed at the rear end of the plastic shell 120, the bottom wall of the box body 410 can cover the rear end of the stator core 110 to form a closed structure, and the side of the box body 410 away from the bottom wall is an open structure, through which the electric control board 500 can be installed in the box body 410.

[0066] Combination Figure 2 As shown, in the embodiment, the motor 1000 also includes a cover body 600, and the cover body 600 is connected to the surrounding edge 411, so that the cover body 600 covers the opening structure, so that the installation space 420 can be defined by the cooperation between the cover body 600 and the surrounding edge 411, and the electric control board 500 can be accommodated through the installation space 420, so that the electric control board 500 will not be exposed, thereby improving the protection effect.

[0067] Specifically, if Figure 4 and Figure 5 As shown, the shape of the cover body 600 matches the shape of the surrounding edge 411, and screw holes are provided on the surrounding edge 411, and the screw holes are located at the corners of the frame. At the same time, openings corresponding to the screw holes are provided on the cover body 600, and screws are passed through the openings to connect with the screw holes, so that the cover body 600 and the box body 410 can be fixedly connected.

[0068] It should be noted that in the embodiment, a plurality of heat dissipation holes 610 are provided on the cover body 600. The heat dissipation holes 610 are in the shape of long strips and are distributed along the surface of the cover body 600. Figure 1 and Figure 2 It can be understood that the cover body 600 can cover the electric control board 500 after being assembled, and the heat generated by the electric control board 500 is dissipated outward through the heat dissipation holes 610, thereby improving the heat dissipation efficiency of the electric control board 500.

[0069] In addition, the cover body 600 is made of plastic material, and the heat dissipation holes 610 and the cover body 600 are integrally formed by injection molding, which is easy to process and has low cost.

[0070] In some embodiments, the mounting structure 400 includes a plastic coating layer (not shown in the drawings), which is formed at the rear end of the plastic package housing 120 and is wrapped around the electric control board 500. Figure 1 and Figure 2 The difference between the illustrated embodiments is that the stator core 110 and the electric control board 500 are injection molded together, so that a plastic coating layer can be formed and the electric control board 500 can be wrapped while the plastic package shell 120 is formed. There is no need to install the electric control board 500 and the cover 600 after the stator 100 is injection molded, thereby simplifying the assembly structure and further reducing the cost of the whole machine.

[0071] Specifically, during assembly, the lead wires of the windings are first welded to the electric control board 500 through the conductive sheet 413, and then the stator core 110, the windings and the electric control board 500 are subjected to a plastic encapsulation process. In this way, the electric control board 500 can be completely wrapped by the plastic layer, and there is no need to add screws or other connecting parts to fix the electric control board 500, so that the assembly is more convenient and quick.

[0072] It can be understood that, compared with the structure of the combination of the box body 410 and the cover body 600, the plastic-encapsulated shell 120 can reduce the number of assembly parts by forming a plastic-encapsulated layer in one piece, and the assembly gap is also reduced accordingly, so the sealing performance for blocking vibration noise is better, the noise reduction effect is better, and it is also beneficial to reduce thermal resistance and improve heat dissipation effect.

[0073] Of course, the plastic coating layer may be provided with heat dissipation holes 610, which help to accelerate the heat dissipation of the electric control board 500 and improve the heat dissipation efficiency of the electric control board 500. The specific form of the heat dissipation holes 610 can be found in Figure 1 and Figure 2 The heat dissipation hole 610 structure of the embodiment shown.

[0074] Reference Figure 1 and Figure 2 As shown, the outer peripheral wall of the plastic shell 120 is provided with a first mounting foot 130 and a second mounting foot 140, wherein two first mounting feet 130 are provided, and the two first mounting feet 130 are arranged at intervals and located at the front end of the plastic shell 120; one second mounting foot 140 is provided, and the second mounting foot 140 is located at the rear end of the plastic shell 120, and the motor 1000 is connected to the washing machine through the first mounting foot 130 and the second mounting foot 140, so that the motor 1000 can be fixedly assembled in the washing machine and obtain stable support.

[0075] It is understandable that the first mounting foot 130 and the second mounting foot 140 are both integrally injection molded with the plastic package shell 120, that is, after the stator 100 is injection molded, the first mounting foot 130, the second mounting foot 140 and the box body 410 are simultaneously formed. Since the motor 1000 needs to be horizontally installed on the washing machine, that is, the axial direction of the rotating shaft 220 is arranged along the horizontal direction after the motor 1000 is installed in place, the first mounting foot 130 and the second mounting foot 140 are arranged on the same side of the motor 1000, so as to facilitate the connection of the motor 1000 with the washing machine.

[0076] In the embodiment, the stator 100 adopts the above structure, which can greatly reduce the number of assembly parts compared to the split structure of the mounting foot and the motor 1000, thereby improving the assembly efficiency of the motor 1000 and reducing the assembly gap, further reducing the possibility of exciting resonance, and achieving better noise reduction effect. It is also beneficial to reduce thermal resistance and improve the heat dissipation efficiency of the motor 1000.

[0077] Specifically Figure 1 and Figure 2 The direction shown is used as a reference direction, and the first mounting foot 130 and the second mounting foot 140 are located at the lower side of the motor 1000, wherein the two first mounting feet 130 are arranged at intervals along the circumference of the plastic shell 120, and the two first mounting feet 130 are respectively provided with a first connecting portion 131, and the first connecting portion 131 is extended along the radial direction of the stator 100, that is, the two first connecting portions 131 are respectively arranged in a direction away from the plastic shell 120, and a first mounting hole 132 is provided on the first connecting portion 131, and the axial direction of the first mounting hole 132 is consistent with the axial direction of the rotating shaft 220.

[0078] It should be noted that in the embodiment, the second mounting foot 140 is a latch structure, specifically in a flat shape, and the second mounting foot 140 is arranged along the axial direction of the stator 100 in a direction away from the plastic package housing 120, that is, the second mounting foot 140 protrudes toward the rear side of the motor 1000. The first mounting foot 130 is also called the front foot of the motor 1000, and the second mounting foot 140 is also called the rear foot of the motor 1000.

[0079] It can be understood that the washing machine is provided with a connecting component corresponding to the first mounting foot 130, and a plug-in hole corresponding to the second mounting foot 140. During assembly, the latch structure is first directly inserted into the plug-in hole of the washing machine, and then the two first mounting feet 130 in front are connected to the connecting component of the washing machine, so that the motor 1000 is fixed. Specifically, the connecting component can be a connecting column, and the connecting column can be directly buckled into the first mounting hole 132 of the first connecting part 131, so that the front and rear ends of the motor 1000 are fixed, and the installation is also simple and quick. Of course, the connecting component is not limited to the connecting column, and the connecting component can be fixed by passing through the first mounting hole 132, for example, it can also be fixed by screws or other forms of components; in addition, the shape of the latch structure is not limited to a flat shape, and can also be set according to actual requirements.

[0080] Since two first mounting feet 130 are located at the front end of the motor 1000 for support, and one second mounting foot 140 is located at the rear end of the motor 1000 for support, and both the first mounting foot 130 and the second mounting foot 140 are located at the lower side of the motor 1000. The embodiment further optimizes the positions of the first mounting foot 130 and the second mounting foot 140. Specifically, in combination with Figure 1 It can be understood that, on the projection plane of the motor 1000 perpendicular to the axial direction of the stator 100, the projection of the latch structure is located between the projections of the two first mounting holes 132, so that the two first mounting feet 130 and the one second mounting foot 140 are distributed non-linearly on the lower side of the motor 1000, specifically in a triangular distribution, and are located on the same plane, which is conducive to forming a stable support, making the installation of the motor 1000 more stable and reliable, and can greatly reduce the number of assembly parts, which has greater advantages in cost savings.

[0081] Of course, this is only an example, and the specific forms of the first mounting foot 130 and the second mounting foot 140 are not limited to the structures shown in the above embodiments. For example, the second mounting foot 140 can also be fixed by means of buckling or the like, and can also adopt the same structure as the first mounting foot 130, that is, the second mounting foot 140 can be connected to the connecting component of the washing machine through the mounting hole; in addition, the number of the second mounting foot 140 is not limited to one, and can also be two or more, for example, two pin structures can be provided to be plugged into the washing machine.

[0082] Since the number and form of the mounting feet of the motor 1000 remain fixed after the first mounting foot 130 and the second mounting foot 140 are injection molded with the plastic shell 120, there is a problem of low compatibility. For example, after the stator 100 is injection molded, two first mounting feet 130 and one second mounting foot 140 are formed, that is, there are three mounting feet, which is only suitable for washing machines with mounting positions corresponding to the three mounting feet reserved, and is not compatible with washing machines that do not match the mounting feet.

[0083] Based on this, refer to Figure 6 As shown, in some embodiments of the present invention, the motor 1000 also includes a third mounting foot 800, and two third mounting feet 800 are provided. The two third mounting feet 800 are arranged at intervals along the circumference of the plastic shell 120, and are detachably connected to the rear end of the plastic shell 120. In this way, after the stator 100 is injection molded, two third mounting feet 800 can be added to the plastic shell 120, so that the motor 1000 has four mounting feet. In other words, the motor 1000 can be switched from three mounting feet to four mounting feet. In this way, the motor 1000 is compatible with washing machines with three mounting positions and four mounting positions, and has better compatibility to meet the needs of different installation methods.

[0084] Reference Figure 7 and Figure 8 As shown, specifically, the two third mounting feet 800 are respectively connected to the plastic shell 120 by bolts 700, so that the third mounting feet 800 and the plastic shell 120 can be detachable, and the operation is easy; the two third mounting feet 800 are both connected to the lower side of the motor 1000, that is, they are located on the same side as the first mounting foot 130, and the two third mounting feet 800 are respectively provided with a second connecting part 810, and the second connecting part 810 is provided with a second mounting hole 811, and the second mounting hole 811 is used to connect with the connecting parts of the washing machine.

[0085] in, Figure 7 The exploded state diagram of the two third mounting feet 800 and the motor 1000 is shown. Figure 8 The diagram shows the assembly state of the two third mounting feet 800 and the motor 1000. It can be understood that in the axial direction of the stator 100, the two third mounting feet 800 correspond to the two first mounting feet 130 after being installed in place, and the second mounting holes 811 and the first mounting holes 132 are both arranged along the axial direction of the stator 100. When installing the motor 1000, the two third mounting feet 800 at the rear end are first connected to the two connecting posts of the washing machine, and then the two first mounting feet 130 at the front end are connected to the other two connecting posts, which is convenient for installation.

[0086] It should be noted that, in the embodiment, the connection positions of the two third mounting feet 800 are respectively located on both sides of the second mounting foot 140, so that the second mounting foot 140 does not affect the assembly of the two third mounting feet 800. The second mounting foot 140 and the third mounting foot 800 are both located on the lower side of the box body 410, and the box body 410 and the mounting feet do not affect each other, which can realize the integrated molding of the box body 410, the first mounting foot 130, the second mounting foot 140 and the plastic package shell 120, and can also add mounting feet according to application requirements, and the layout design is reasonable.

[0087] In addition, the number of the third mounting feet 800 is not limited to two, and one, three or more can be provided according to actual requirements; and the form of the third mounting feet 800 is also not limited to Figure 7 and Figure 8 The structure shown may also be in the form of a latch structure, for example, connected to the plastic housing 120 via a detachable latch, so that the rear end of the motor 1000 may be provided with one, two or more latches.

[0088] Reference Figure 6 and Figure 7 As shown, in the embodiment, the motor 1000 further includes a connecting member, which is specifically a bolt 700. The outer peripheral wall of the plastic-encapsulated housing 120 is formed with a boss 150, and a through hole is formed on the boss 150. The through hole is arranged along the axial direction of the stator 100. Since the end cover 300 is located at the front end of the stator 100 and needs to be connected to the plastic-encapsulated housing 120 by the bolt 700, the embodiment uses the connecting member such as the bolt 700 to penetrate the through hole, and the end cover 300 is locked together with the third mounting foot 800 to improve the assembly efficiency.

[0089] It can be understood that in the embodiment, the end cover 300 is fixed by three bolts 700, wherein the two bolts 700 on the lower side penetrate the plastic housing 120 and are respectively connected to the two third mounting feet 800, so that the end cover 300 and the third mounting feet 800 can be quickly assembled into place, with higher assembly accuracy and better sealing, which is conducive to reducing the generation of vibration noise, and the overall assembly structure of the motor 1000 is also more stable and reliable.

[0090] An embodiment of the present invention further provides a washing device, which may be a washing machine, a dryer or other washing appliances. Taking a drum washing machine as an example, the motor 1000 of the above embodiment is adopted, and the motor 1000 is installed in the drum washing machine. The motor 1000 is connected to the connecting parts or other fixed structures of the drum washing machine through the first mounting foot 130 and the second mounting foot 140.

[0091] A plastic-sealed shell 120 is formed on the stator core 110 by a plastic-sealing process, and a mounting structure 400 is provided on the plastic-sealed shell 120, so that the mounting structure 400 and the plastic-sealed shell 120 form an integral structure, and the mounting structure 400 is used to accommodate the electric control board 500, so that the electric control board 500 and the stator 100 are assembled into an integral structure, so that one end of the stator 100 is assembled with the end cover 300, and the other end forms a closed structure through the mounting structure 400, which can reduce the assembly gap and the number of assembly parts between the electric control board 500 and the stator 100, so that the motor 1000 is not easy to excite resonance, thereby effectively reducing the vibration noise of the washing machine.

[0092] Since the washing device adopts all the technical solutions of the motor 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0093] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
