Description
Technical Field
The present invention relates to a stator for a motor of a washing machine. More particularly, the present invention relates to a stator for a motor of a washing machine, which can prevent vibration of the motor from being transmitted to the washing machine and reduce manufacturing costs by preventing noise and vibration from being generated when the motor for the washing machine is operated.
Background
In general, a motor for a washing machine may include a rotor and a stator. Wherein, the stator includes: a stator core made of a plurality of thin metal steel plates laminated together; and an insulator surrounding the stator core, wherein the upper insulator and the lower insulator surrounding the stator core are in contact with each other, thereby forming a structure that substantially covers the inner peripheral surface of the stator core. According to this structure, when the motor is operated, noise due to minute vibrations can be generated in the vicinity of the boundary of the two insulators, and since the insulators cover almost most of the inner circumferential surface of the stator core, the amount of resin molding to be consumed is relatively large, resulting in an increase in manufacturing cost.
In order to reduce noise caused by motor vibration, there may be included as a prior art: korean patent No. 10-0577255, which has been filed to enable bolts for coupling a motor bracket and a stator to be combined with a dustproof pad flexible in material to reduce motor vibration; korean patent No. 10-0571790, which discloses a dust-proof member applied to a coupling bolt of a motor housing; and korean patent No. 10-1154983, in which a lower cover member coupled to an outer tub and supporting a rotor is coupled to an upper insulator and a lower insulator in a state of being in contact with each other by coupling bolts, a contact protrusion (buffer member) is disposed between a protrusion of a lower portion of the lower insulator and a coupling portion of the outer tub to reduce vibration, and since the above conventional art is a structure in which coupling portions formed by coupling the upper insulator and the lower insulator are in contact with each other, noise due to vibration may be generated at a portion where an inner side of the upper insulator and an inner side of the lower insulator are in contact, particularly in a motor assembly, that is, since the lower cover member coupled to the outer tub and the lower insulator of synthetic resin are coupled in a state of being in contact with each other, even if vibration is absorbed by the above dust-proof member or the like, it is impossible to prevent noise from being generated at the opposite contact portion, and thus the problem of vibration and noise has not been solved.
Thus, in order to solve the above-described problems, the present inventors have provided a stator for a motor of a washing machine having a novel structure.

Detailed Description
Fig. 1 is a perspective view showing a stator 1 of a motor of the present invention, fig. 2 is a perspective view showing the stator 1 of the motor of the present invention as seen from below, fig. 3 is an exploded perspective view showing a part of the stator 1 of the motor of the present invention, and fig. 4 is an exploded perspective view showing the stator 1 of the motor of the present invention. As shown in fig. 1 to 4, a stator 1 of a motor of the present invention is composed of an upper insulator 10, a lower insulator 20, and a stator core 30.
The upper insulator 10 and the lower insulator 20 are coupled to the upper and lower portions of the stator core 30 in an insulated manner. The stator core 30 is manufactured by laminating a plurality of thin steel plates, and has a circular core base 31 and a plurality of teeth 32 radially formed on the core base 31. When the upper insulator 10 and the lower insulator 20 are coupled to the upper and lower portions of the stator core 30, the lower surface of the upper insulator 10, the upper surface of the lower insulator 20, and the respective inner circumferential surfaces are formed at predetermined intervals so as not to be in direct contact with each other.
The upper insulator 10 is coupled to the stator core 30 in such a manner as to cover an upper portion of the stator core 30, and includes: an upper base cover 11 covering an upper portion of the core base 31 of the stator core 30; an upper tooth cover 12 covering an upper portion of the tooth 32; and an upper inner Zhou Mianzhao part 13 covering an upper side of an inner peripheral surface of the core base 31 of the stator core 30. A plurality of protruding members 110 are formed around the inner side along the radial direction of the upper inner peripheral surface cover portion 13 of the upper insulator 10, the plurality of protruding members 110 having correction holes 110A, the plurality of protruding members 110 protruding inward from the upper inner Zhou Mianzhao portion 13, the correction holes 110A being used to correct the accurate position when the stator 1 is coupled to the motor assembly. As shown in fig. 1, at least 3 protruding members 110 are preferably formed to protrude with a prescribed interval.
The lower insulator 20 is coupled to the stator core 30 in such a manner as to cover a lower portion of the stator core 30, and includes: a lower base cover 21 extending along the inside so as to cover the lower portion of the core base 31 of the stator core 30; a lower tooth cover 22 covering the lower portion of the tooth 32; and a lower inner Zhou Mianzhao portion 23 forming an inner peripheral surface of the lower insulator 20. A plurality of module coupling parts 210 having coupling holes 210A and a plurality of weight reducing spaces 210B are formed at the outer side in the radial direction of the lower inner Zhou Mianzhao part 23 of the lower insulator 20, and a lower coupling concave part 220 is formed at the lower part of the module coupling parts 210. Although there is no particular limitation on the number of the assembly coupling parts 210, it is only required to be the same as or more than the number of the protruding members 110, but it is preferable that a part thereof must be formed adjacent to the protruding members 110. In this specification, 6 assembly joints 210 are used as an example. Of these, 3 assembly joints 210 are adjacent to the protruding members 110, and the remaining 2 are located between the two protruding members 110.
The upper buffer member 40 is press-fitted and fixed to the upper end portion of the bush 50, the bush 50 is press-fitted into the coupling hole 210A of the assembly coupling portion 210, and the upper buffer member 40 having the coupling hole 40-1 formed therein is positioned at the upper placement portion 210A-1 around the coupling hole 210A. In order to effectively absorb vibration and noise and eliminate interference of other components generated when the motor is combined with the assembly, it is preferable that the upper buffer member 40 has a cut surface 40A and an outer circumferential surface 40B, the cut surface 40A is a portion of a cut-off ring shape, and the outer circumferential surface 40B is a circular outer circumferential portion.
In this case, one surface of the outer peripheral surface 40B of the upper cushion member 40 is in contact with the upper inner peripheral surface cover 13 of the upper insulator 10. At the same time, one side surface of the protruding member 110 is in contact with a part of the outer peripheral surface 40B of the upper buffer member 40, and the upper insulator 10 and the lower insulator 20 are maintained to be coupled to the stator core 30 in a state where one side surface of the upper buffer member 40 presses and is supported by one side surface of the protruding member 110 of the upper insulator 10. As described above, by maximizing the facing contact area between one side surface of the buffer member 40 and one side surface of the protruding member 110 of the upper insulator 10, the buffer member 40 can be made to effectively absorb vibration and prevent noise.
Since the upper cushion member 40, which is not located adjacent to the module coupling portion 210 and the protruding member 110, cannot be brought into contact with the protruding member 110, it is brought into contact with only the upper inner peripheral surface cover portion 13.
As described above, the present invention is constructed in such a manner that the upper insulator 10 covers the core base 31 of the stator core 30 and the upper portion of the tooth 32 in an insulating manner, and the lower insulator 20 covers the lower portion of the core base 31 and the lower portion of the tooth 32 in an insulating manner, in such a manner that one side surface of the upper buffer member 40 presses and is supported by one side surface of the protruding member 110 of the upper insulator 10 in a state where the upper insulator 10 and the lower insulator 20 are coupled by press-fitting of the stator core 30, respectively. Also, the amount of resin molding and the manufacturing cost can be reduced by forming the weight-reducing space 210B in the lower insulator 20.
A lower coupling recess 220 formed to be recessed toward an upper portion is formed at a lower portion of the assembly coupling portion 210 of the lower insulator 20, a plurality of weight reducing spaces 210B are formed around the lower coupling recess, and the bushing 50 is press-coupled to a coupling hole 210A penetrating the assembly coupling portion 210.
Since the upper insulator 10 covers the upper portion of the stator core 30, the upper insulator 10 is composed of an upper base cover 11 covering the upper portion of the core base 31, an upper tooth cover 12 covering the upper portion of the tooth 32, and an upper inner peripheral surface cover 13 covering the core inner peripheral surface 33. The lower insulator 20 includes a lower base cover 21 and a lower tooth cover 22, the lower base cover 21 is a portion covering a lower portion of the core base 31 of the stator core 30, the lower tooth cover 22 is a portion covering a lower portion of the tooth 32, and a lower inner peripheral surface cover 23 is formed on an inner peripheral surface of the lower insulator 20. A lower coupling recess 220 and a weight-reducing space 210B are formed at the lower base cover 21.
The bushings 50 are respectively pressed into the coupling holes 210A of the lower insulator 20. The upper buffer member 40 is positioned at the upper placement portion 210A-1 around the coupling hole 210A, and the coupling hole 40-1 of the upper buffer member 40 is press-fitted to the upper end of the bush 50 press-fitted to the coupling hole 210A so as to protrude toward the upper portion of the coupling hole 210A.
Fig. 5 is a sectional view showing an exploded state of the stator 1 of the motor of the present invention, and fig. 6 is a sectional view showing the stator 1 of the motor of the present invention. Referring to fig. 5 and 6, in a state where the upper cushion member 40 is fitted into the upper end of the bushing 50, the bushing 50 is fitted into the coupling hole 210A formed in the assembly coupling portion 210 of the lower insulator 20 while maintaining a state of elastic compression by the upper inner peripheral surface cover portion 13 of the upper insulator 10 being in contact with a part of the outer peripheral surface 40B of the upper cushion member 40.
Fig. 7 and 8 are enlarged cross-sectional views showing a part of a stator of a motor according to the present invention. As shown in fig. 7 and 8, the side surface 110B of the protruding member 110 having the plurality of correction holes 110A is brought into contact with the outer peripheral surface 40B of the upper cushion member 40, whereby the outer peripheral surface 40B of the upper cushion member 40 coupled to the lower insulator 20 presses and is supported by the side surface 110B of the protruding member 110 of the upper insulator 10.
Therefore, the outer peripheral surface 40B of the upper cushion member 40 is strongly elastically pressed against the side surface 110B of the protruding member 110 and the side surface of the upper inner Zhou Mianzhao portion 13 of the upper insulator 10, so that a firm coupling state can be maintained. In order to perform the cushioning and vibration-proof functions, the upper cushioning member 40 is preferably made of a material that absorbs impact and vibration, such as rubber, but is not limited to rubber, and various materials other than rubber, such as silicon, polyurethane, aluminum die-cast alloy, other plastics, metal, etc., may be used as required.
As shown in fig. 6, the lower surface of the upper inner Zhou Mianzhao portion 13 of the upper insulator 10 and the assembly coupling portion 210 of the lower insulator 20 are spaced apart from each other with a predetermined interval therebetween in a coupled state, so that minute vibration and noise generated at the boundary portion can be prevented.
Fig. 8 is an enlarged cross-sectional view showing a part of a stator 1 of a motor of the present invention. Referring to fig. 8, the insertion protrusion 210A-10 protruding toward the upper portion of the upper placing portion 210A-1 may be coupled with the insertion hole formed at the lower portion of the upper buffer member 40, the upper placing portion 210A-1 being located around the coupling hole 210A formed at the assembly coupling portion 210 of the lower insulator 20. Thus, the assembly and the coupling of the upper cushion member 40 can be performed promptly, and the coupling in the firm state can be maintained by preventing a minute movement in the coupled state.
The stator 1 of the motor is coupled to a motor unit (not shown), and the stator 1 is coupled to the motor unit as the coupling bolts 60 penetrate along the inner side of the bushing 50. In this case, the ring-shaped lower buffer member 70 may be positioned at the lower coupling recess 220 of the lower insulator 20. The lower protruding surface 70A of the lower cushioning member 70 located in the lower coupling recess 220 protrudes further downward than the lower end surface of the lower insulator 20. That is, the lower protruding surface 70A of the lower buffer member 70 is in contact with the upper surface 80A of the lower cover member 80, the lower cover member 80 is coupled to the outer tub constituting the motor assembly, and is made of a metal or synthetic resin material, the stator 1 is coupled to the lower cover member 80 by the coupling bolt 60, and the motor assembly is coupled to the stator 1 without direct contact by using the lower buffer member 70 at the coupling portion of the stator 1 and the motor assembly, thereby preventing noise due to vibration generated by contact.
The above detailed description of the present invention is merely an example for understanding the present invention, and does not limit the scope of the present invention. The scope of the present invention can be defined by the scope of the appended claims, and it should be understood that all modifications or changes to the present invention within the scope thereof fall within the scope of the present invention.
