Compare with the washing machine of prior art among Fig. 1, except the structure of stator, washing machine of the present invention is different significantly with the washing machine of prior art.Therefore, will describe the stator that the present invention proposes below, and omit description other element.
Fig. 3 illustrates the plane graph according to the stator of preferred implementation of the present invention, and Fig. 4 illustrates the upward view of the stator among Fig. 3.
With reference to figure 3 and 4, insulator 110 is fastened to stator core 140, and the fastening part 120 that is arranged in the inboard of stator utilizes coupling part 130 to be connected to insulator 110 respectively.
Preferably, the fastening part 120 of stator of the present invention, insulator 110 and coupling part 130 all form a unit through plastic injection molded.In addition, preferably, be inserted in state injection molded fastening part 120, insulator 110 and coupling part 130 in the mould, make fastening part 120, insulator 110 and coupling part 130 combine with stator core 140 at stator core 140.
In this case, insulator 110 is sealed the utmost point 141 of stator core 140, and as insulator.Accompanying drawing illustrates the part of sealing the utmost point 141 of insulator 110, and coil 101 is wrapped in respectively on the said part.
Stator utilizes fastening bolt firmly to be fixed to the rear portion of the cylinder bucket of the washing machine among Fig. 1.Above-mentioned fastening in order to carry out, fastening part 120 has the fastener hole that is used for passing bolt.Preferably, at bolt and fastening part 120 or between cylinder bucket and fastening part 120, have the packing ring (not shown).
Simultaneously, the coupling part 130 that vertically forms has a plurality of vertical ribs 131～135, so that fastening part 120 is connected to insulator 110 vertically.
Middle vertically rib 133 is connected to insulator 110 with beeline with fastening part 120.As shown in the figure, preferably, if vertically rib is arranged on the line stretcher B and C of the nearest utmost point 141, then vertical rib is arranged such that the direction of line stretcher B and C, and the arranged direction with vertical rib is different respectively.
Middle vertically rib 133 is arranged between the line stretcher B and C of two adjacent utmost points, and other vertical rib 131,132,134 and 135 is arranged to about vertical rib 133 symmetries in centre.That is to say that preferably, the first vertical rib 131 and the second vertical rib 132 are arranged to be symmetrical in the 4th vertical rib 135 and the 3rd vertical rib 134 about the vertical rib 133 in centre.Between the first vertical rib 131 and the second vertical rib 132, can have locator protrusions 138.
Simultaneously, vertically rib 131～135 is connected with horizonal web plate 136, and horizonal web plate 136 has the tap 137 that is formed on wherein.Preferably, the vertical rib 131～135 of fastening part 120 and coupling part 130 is vertically about horizonal web plate 136 symmetries.That is to say that shown in Fig. 3 and 4, except locator protrusions 138, the top of fastening part 120 and coupling part 130 and bottom be symmetry respectively.
If the vertical rib 131～135 of coupling part 130 is vertically asymmetric; The stress that then is applied to the upper and lower of fastening part 120 by the heat expansion of vertical rib 131～135 or shrinkage being used to of causing will be different; Thereby cause another problem, promptly damage the intensity of fastening part 120.Therefore, if vertically rib 131～135 is vertically symmetrical about horizonal web plate 136, then can address the above problem.
Therewith together, with reference to figure 3 and 4, preferably, fastening part is along the inboard that is arranged in stator core 140 interior week symmetrically of stator core 140.That is to say that each in the fastening part all has relative fastening part, and other fastening part is about connecting the line symmetry of each fastening part relative with it in the fastening part.This symmetric arrangement of fastening part makes the center of stator can easily be positioned to the part of cylinder bucket, and a said part is the residing part in center of stator when stator is mounted to the cylinder bucket.
In addition, with reference to figure 6, stator core 140 can have through hole 143, so that the plastics of fusion are passed through to connect the upper and lower of insulator 110.In this case, the part that is filled in the through hole 143 of insulator 110 makes core 140 firmer with being connected of insulator 110.In addition, the part that is filled in the through hole 143 reduces the thermal deformation of insulator 110 and fastening part 120, thereby reduces to be applied to the stress of fastening part 120.
Simultaneously, being used to inject the gate portions 112 of molten plastic can be along circumferential rib 111 location.Preferably, gate portions 112 is not to be positioned on the line stretcher D at center of each center that connects fastening part 120 and stator core 140, but with the spaced apart preset distance of line stretcher D.
Be similar to the imaginary gate portions 113 shown in Fig. 5, if gate portions is positioned on the line stretcher D, path 114 can merge the formation boundary face with right side path 115 at the center of fastening part 120 on the left of then molten plastic will flow through.Because a little less than other part of the strength ratio of boundary face, so boundary face may be the reason that fastening part 120 breaks.Therefore, gate portions 112 is arranged to the spaced apart certain distance with line stretcher D.
With reference to figure 6, preferably, the through hole 143 in the part of gate portions 112 and the stator core 140 is overlapping at least, so that molten plastic is downward through through hole 143 reposefully.
With reference to figure 3～5, the height of fastening part 120 is greater than the height of the vertical rib 131～135 of coupling part 130.If vertically the height of rib 131～135 is greater than the height of fastening part 120, then be placed on 120 last times of fastening part at packing ring, packing ring can interfere with each other with vertical rib 131～135, thereby makes the practical fastening failure of stator to the cylinder bucket.If between packing ring and fastening part 120, have the gap, then the gap is easy to cause during operation that stator unclamps from the cylinder bucket.This is because caused by the thermal deformation of the caused fastening part 120 of the driving of motor etc., although no matter whether the gap exists stator can when initial, be fastened to the cylinder bucket tightly.
Industrial applicibility
The present invention can provide a kind of stator fastening structure, because folder thing injection-molded, this stator fastening structure is much firmer than in the past, has improved operating efficiency, and has realized the fastening more reliably of stator.
In addition, the present invention can provide a kind of washing machine, this washing machine has the stator that is fastened to the cylinder bucket more reliably, and the splintering problem of the fastening part that has prevented during operation to be caused by thermal deformation.
