The first mounting leg 23 is fixedly coupled to an external structure such as a water storage tub. The first mounting leg 23 may be provided with a mounting hole or the like for facilitating connection with an external structure. The water deflector 22 is provided with a terminal box mounting portion 220 for mounting the terminal box. The terminal box mounting portion 220 may be selected to be a through hole or a groove structure.
Embodiment two:
referring to fig. 5 and 6, the difference between the second embodiment and the first embodiment is that: the support mounting portion is formed by extending the second flange portion 21a toward the first flange portion 11 in the first embodiment, and forms the support mounting portion (the second flange portion 21 b) in the second embodiment, that is, the support mounting portion is integrally formed with the second flange portion 21b while supporting the first flange portion 11. In this embodiment, the middle core of the stator assembly 3b need not extend radially.
Optionally, an outlet port 25 is provided on the second end cap 2 for connection to a controller or washing machine. The outlet port 25 is formed in the second end cap 2, so that the strength of the second end cap 2 is not reduced. When the outlet port 25 is provided on the first end cap 1, since the first end cap 1 is thin, strength at the outlet port 25 may be affected.
Embodiment III:
referring to fig. 7, the difference between the third embodiment and the second embodiment is that: the support mounting portion 6 is a support sleeve or a spacer, and is interposed between the first flange portion 11 and the second flange portion 21 a. The support sleeve or the cushion block is provided with a second connecting hole 3310 for the fastener to pass through. The support mounting portion 6 is also configured as a support sleeve or a spacer, and can support the first flange portion 11.
Embodiment four:
referring to fig. 8 and 9, the fourth embodiment is different from the first embodiment in that: the motor further comprises a controller and a controller cover 5, wherein the controller cover 5 is fixed on the first end cover 1, the controller is arranged in the controller cover 5, and the controller can be fixed on the first end cover 1, fixed on the controller cover 5 or pressed on the first end cover 1 by the controller cover 5. The second mounting feet 51 are arranged on the outer side of the controller cover 5, so that when the motor is fixed to an external structure such as a water storage bucket, a mounting structure is not required to be arranged on the first end cover 1, the first end cover 1 can adopt processes such as stretching and injection molding, the structure of the first end cover 1 is simplified, the second mounting feet 51 are arranged on the controller cover 5 in a transferring mode, the controller and the motor form an integrated structure, the structure of the first end cover 1 is simplified, and the cost of the first end cover 1 is saved. The first mounting leg 23 and the second mounting leg 51 are commonly mounted to an external structure, making the mounting of the motor more stable. The first mounting leg 23 and the second mounting leg 51 may be provided with mounting holes for mounting connectors such as screws.
Optionally, the surface of the controller cover 5 has heat dissipating ribs to enhance heat dissipation of the controller cover 5.
Alternatively, the controller housing 5 and the second mounting leg 51 are formed separately or integrally. The controller cover 5 may be injection molded from a bulk molding material, a resin material, or the like. The second mounting leg 51 may be made of an aluminum alloy, a bulk molding compound, a resin material, or the like.
The application also provides a washing machine comprising the motor in any of the above embodiments. The motor comprises a first end cover 1, a second end cover 2, a fastener used for connecting the first end cover 1 and the second end cover 2, a stator assembly and a rotor assembly 4, wherein the first end cover 1 is stretched or injection molded, the wall thickness of the first end cover is thinner, the strength of the first end cover is lower, a first flange part 11 used for connecting the fastener is arranged on the first end cover 1, and a second flange part used for connecting the fastener is arranged on the second end cover 2. By providing the support mounting portion between the first flange portion 11 and the second flange portion, the first end cap 1 can be prevented from being deformed by pressing at the time of assembly; in addition, the first matching surface 12 of the inner wall of the first end cover 1 is in abutting matching with the second matching surface 311 of the outer periphery of the stator assembly, so that the stator assembly can be wrapped, the strength of the stator assembly is enhanced, and the noise of the stator assembly in the working process of the motor is reduced.
Optionally, the washing machine further comprises a water storage tub to which the motor is fixed by the above-mentioned first and second mounting feet 23 and 51.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
