Example Embodiment

[0029] like Figure 1 to Figure 4 As shown, the washing machine direct drive clutch device of the present invention includes a direct drive motor 1 installed at the bottom of the outer tub, the direct drive motor 1 directly transmits a pulsator shaft 2 that drives the pulsator, and is coaxially sleeved outside the pulsator shaft 2 to drive the dehydration tub The rotating dewatering shaft 3 is used to transmit the drive of the direct drive motor 1 to the pulsator shaft 2 or to the pulsator shaft 2 and the dewatering shaft 3 at the same time. The upper and lower split-type clutch structure is tightly combined with the motor rotor 11. A clutch outer disc 4 that rotates together, a clutch inner sleeve 5 that is connected to the dehydration shaft 3 and can drive the dehydration shaft 3 to rotate together and can slide axially on the dehydration shaft 3, and a set of the dehydration shaft 3 to provide elastic force so that the clutch inner The sleeve 5 is axially slidably connected...

Abstract

The invention discloses a direct drive engaging and disengaging device of a washing machine, which comprises a direct drive motor, a vertical split type engaging and disengaging structure and a brake structure, wherein the direct drive motor is arranged at the bottom of an outer barrel and used for directly driving an impeller shaft of an impeller and a dewatering shaft coaxially sleeved outside the impeller shaft for driving a dewatering barrel to rotate; the engaging and disengaging structure is used for singly transmitting the drive of the direct drive motor to the impeller shaft or simultaneously transmitting the drive to the impeller shaft and the dewatering barrel and comprises an engaging and disengaging outer disk, an engaging and disengaging inner sleeve and an engaging and disengaging spring, wherein the engaging and disengaging outer disk is tightly combined with a motor rotor and rotates together with the motor rotor, the engaging and disengaging inner sleeve is sleeved on the dewater barrel, can be used for driving the dewatering shaft to rotate together and can axially slide on the dewatering shaft, and the engaging and disengaging spring is sleeved on the dewatering shaft and used for providing elastic force to ensure that the engaging and disengaging inner sleeve axially slide and is internally engaged and connected with the engaging and disengaging outer disk; and the brake structure is used for separating the engaging and disengaging inner sleeve from the engaging and disengaging outer disk up and down. The device has the advantages of simple structure and low cost and can be used for improving the efficiency of a transmission system and realizing stable engaging and disengaging control.

Description

technical field [0001] The invention relates to a clutch device of a washing machine, in particular to a clutch device of a direct-drive washing machine. Background technique [0002] The rotation of the pulsator and the inner barrel of the traditional washing machine is that the motor drives the belt through the pulley to transmit the power to the deceleration clutch. For different washing methods, the deceleration clutch uses different gear structures to transmit different rotation directions and rotation forms to the pulsator. [0003] In this structure, since the deceleration clutch and the motor are horizontally arranged at the bottom of the outer barrel, the structure of the whole system is relatively large. On the other hand, the deceleration clutch is located at the center of the outer barrel, the position of the motor deviates from the center, and the center of the entire structure at the bottom of the outer barrel deviates from the center hole of the outer barrel....
