[0001] The utility model relates to the technical field of washing machine linkage devices, in particular to a washing machine dehydration clutch linkage component. Background Art

[0002] During the washing process, the impeller and the inner drum of the washing machine rub each other, that is, while the impeller rotates clockwise, the inner drum rotates counterclockwise. The two-way rotation of the impeller and the inner drum generates a strong water flow, simulating the rubbing effect, penetrating deeply into the fibers of clothes, increasing the washing area of ​​clothes, thoroughly removing stains, and powerfully cleaning clothes, while reducing entanglement of clothes.

[0003] For example, Chinese patent application number CN201210320303.2 discloses a differential linkage device for a washing machine. Specifically, when the washing machine is in the dehydration mode, the electromagnetic coil stops being energized, and the clutch ring gear slides downward under the action of its own weight and the return spring. The prongs at the lower end of the clutch ring gear insert into the slots on the slot disk, locking the clutch ring gear and the slot disk. Because the clutch ring gear remains engaged with the gear ring, and the gear ring remains engaged with the gear, the clutch ring gear, the gear ring, and the gear rotate at the same speed and in the same direction, causing the impeller and inner drum of the washing machine to rotate in the same direction and at the same speed. This presents the following technical problems:

[0004] The common clutch gear ring is an integrated setting. After the washing machine is used for a long time, the teeth are easily damaged due to wear. Therefore, the entire clutch gear ring needs to be replaced, which easily causes waste of resources. Utility Model Content

[0031] A spring 310 is mounted on the upper end of the upper ring gear 330, controlling the downward movement of the clutch ring gear 300. When the washing machine is in the wash mode, the electromagnetic coil is energized, and the clutch ring gear 300, under the magnetic attraction of the electromagnetic coil, overcomes the spring 310 and slides upward, locking with the mounting bracket. When the washing machine is in the spin mode, the electromagnetic coil is de-energized, and the clutch ring gear 300 slides downward under its own weight and the action of the spring 310. The lower end of the clutch ring gear 300 engages and locks with the slot plate 11, thereby causing the impeller and inner drum of the washing machine to rotate in the same direction and at the same speed.

[0032] The clutch gear ring 300 includes a positioning ring 320, the upper end of the positioning ring 320 is equipped with an upper gear ring 330 for engaging with the internal mounting frame of the washing machine, and the lower end of the positioning ring 320 is equipped with a lower gear ring 340 for engaging with the slot disk 11.

By tilting the first bevel groove 322, when the ring body 321 rotates, the first bevel block 333 and the groove cavity of the first bevel groove 322 are clamped, which can increase the connection strength between the ring body 321 and the upper ring gear 330 and reduce damage to the hexagon socket bolt 350.

[0034] The lower end of the ring body 1 321 is machined with a second beveled groove 323 for fastening the lower ring gear 340. The first beveled groove 322 and the second beveled groove 323 are inclined in opposite directions. The inclined second beveled groove 323 ensures that when the pulsator and inner tub of the washing machine rotate in the same direction and at the same speed, the second beveled block 343 and the groove cavity of the second beveled groove 323 are clamped, which can increase the connection strength between the ring body 1 321 and the lower ring gear 340 and reduce damage to the hexagon socket bolts 350. The middle portion of the ring body 1 321 is machined with multiple through holes 324 for retaining the hexagon socket bolts 350.

[0035] The upper gear ring 330 includes a second ring body 331 , the upper end of which is processed with a first slot 332 , and the lower end of which is installed with a plurality of first inclined blocks 333 that engage with the first inclined groove 322 , and the inclination directions of the first inclined blocks 333 and the first inclined groove 322 are consistent.

[0036] The middle portion of the second ring body 331 is machined with a plurality of first mounting holes 334 for retaining the hexagon socket bolts 350. Nuts that match the hexagon socket bolts 350 are installed in the grooves of the first mounting holes 334, and the thickness of the nuts is less than the depth of the grooves of the first mounting holes 334. A baffle 335 for supporting the spring 310 is installed at the upper end of the second ring body 331. A retaining ring 336 for retaining the spring 310 is installed in the middle of the baffle 335. The hexagon socket bolts 350 are sleeved on the outside of the retaining ring 336.

[0037] The lower gear ring 340 includes a ring body 341, and the lower end of the ring body 341 is processed with a second slot 342 for easy engagement with the slot disk 11, so that when the drive shaft 10 drives the slot disk 11 to rotate, the ring body 341 is synchronously driven to rotate, and the upper end of the ring body 341 is installed with a second inclined block 343 for engaging with the second inclined groove 323, and the inclination direction of the second inclined block 343 and the second inclined groove 323 is consistent. The middle part of the ring body 341 is processed with multiple second mounting holes 344 for limiting the hexagon socket bolts 350.

[0038] When the upper gear ring 330 or the lower gear ring 340 is severely worn and needs to be replaced, it is only necessary to remove the hexagon socket bolt 350 to replace the upper gear ring 330 and the lower gear ring 340 separately, avoiding the waste of resources caused by replacing the entire clutch gear ring 300.
