Example Embodiment

[0036] Example one

[0037] Such as figure 1 As shown, the clutch device in this embodiment includes a dehydration pin 6 installed at the lower end of the brake wheel 5, a clutch sleeve 3 installed at the input shaft sleeve 2 and rotating integrally with the input shaft sleeve, and a brake installed at the lower end of the housing 15. The drive unit that the pin 4 and the drive clutch sleeve 3 are connected to / disconnected with the dehydration pin 6 and the brake pin 4 respectively;

[0038] In the washing state, the driving unit controls the clutch sleeve 3 to be connected to the brake pin 4 and disconnected from the dehydrating pin 6; in the dehydrating state, the driving unit controls the clutch sleeve 3 to be connected to the dehydrating pin 6 and disconnected from the brake pin 4.

Example Embodiment

[0039] Example two

[0040] Such as figure 2 As shown, the clutch device described in this embodiment includes a dewatering pin 6 installed on the input shaft 1, a clutch sleeve 3 installed on the input shaft sleeve 2 and rotating integrally with the input shaft sleeve, and a brake pin 4 installed on the lower end of the housing 15. And the drive unit that the drive clutch sleeve 3 is connected to / disconnected with the dehydration pin 6 and the brake pin 4 respectively;

[0041] In the washing state, the drive unit controls the clutch sleeve 3 to be connected to the brake pin 4 and disconnected from the dehydration pin 6; in the dehydration state, the drive unit controls the clutch sleeve 3 to be connected to the dehydration pin 6 and disconnected from the brake pin 4.

Example Embodiment

[0042] Example three

[0043] In the above embodiment, the clutch sleeve 3 is slidably mounted on the input shaft sleeve 2 up and down, and can rotate integrally with the input shaft sleeve; the clutch sleeve 3 is controlled to slide up and down through the drive unit to spline connection with the dehydration pin 6, the brake pin 4. When disconnected, the drive unit includes a return spring and a device for driving the clutch sleeve to act. The device is electromagnetically driven or mechanically driven, such as an electromagnetic clutch coil or shift fork structure.

Abstract

The invention discloses a reduction clutch for a washing machine and the washing machine. The reduction clutch comprises an input shaft, an input shaft sleeve, a brake wheel, a reducer, a dewatering shaft, an output shaft, a clutch device and a shell. The input shaft sleeve is installed on the input shaft in a sleeving mode, the dewatering shaft is installed on the output shaft in a sleeving mode, the reducer is installed on an inner cavity of the brake wheel, and the input shaft, the input shaft sleeve, the brake wheel and the output shaft are connected with the reducer respectively. The reducer is a double planetary gear train and comprises a first planetary gear train and a second planetary gear train, and the first planetary gear train and the second planetary gear train use a same planet carrier. The input shaft sleeve and the second planetary gear train are connected into one, the dewatering shaft and the brake wheel are connected into one, the output shaft is connected with input shaft in a transmission mode through the first planetary gear train, and the dewatering shaft is connected with the output shaft in a transmission mode through the brake wheel and the second planetary gear train. The conversion between the washing condition and the dewatering condition is controlled through the clutch device. The reduction clutch for the washing machine and the washing machine have the advantages that the structure is simple and compact, the manufacturing cost is low, the transmission is safe, reliable and efficient, the service life is long, and the noise is low.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine deceleration clutch and a washing machine. Background technique [0002] At present, the function of the deceleration clutch of the pulsator type washing machine is generally to drive the pulsator to reciprocate after decelerating the bidirectional rotation of the motor. The conventional deceleration clutch is mainly composed of an input shaft, an output shaft, an output shaft sleeve, an input shaft sleeve, a brake wheel, a reduction mechanism installed inside the brake wheel, and a clutch component installed on the input shaft sleeve. In washing conditions, the output shaft is required to rotate repeatedly at low speed in both directions. The output shaft sleeve and the brake wheel are integrated. The deceleration mechanism generally only plays a simple deceleration role. When the brake wheel is braked, the output shaft sleeve is also restrained. The two-way ro...
