Embodiment 1

[0038] Such as figure 1 As shown, in this embodiment, the drive device is two rotors and a stator, respectively the first rotor 4, the second rotor 5 and the stator 6, the first rotor 4 and the second rotor 5 are both inner rotors, The stator 6 is the outer stator, the pulsator shaft 31 is coaxially arranged in the inner barrel shaft 21, the first rotor 4 is connected to the inner barrel shaft 21, the second rotor 5 is connected to the pulsator shaft 31, and the stator is fixed under the outer barrel through a mounting plate (in the figure not shown).

[0039] The washing machine in this embodiment is a dual-power washing machine, that is, the first rotor 4 and the second rotor 5 are controlled to drive the pulsator 3 and the inner tub 2 to rotate at different or the same speeds in opposite directions during washing, and to drive the pulsator 3 during dehydration. Rotate in the same direction and at the same speed as the inner barrel 2.

Embodiment 2

[0041] Such as figure 2 As shown, the difference between this embodiment and the first embodiment is that the first rotor 4 and the second rotor 5 are both outer rotors, and the stator 6 is an inner stator.

[0042] In the washing machine in this embodiment, the first rotor 4 and the second rotor 5 are controlled to drive the pulsator 3 and the inner tub 2 to rotate in the same direction and at different speeds respectively during washing, and to drive the pulsator 3 and the inner tub 2 to rotate in the same direction and at the same speed during dehydration.

Embodiment 3

[0044] Such as image 3As shown, in the present embodiment, among the two rotors, the first rotor 4 is an outer rotor, the second rotor 5 is an inner rotor, the stator 6 is arranged between the first rotor 4 and the second rotor 5, and the pulsator shaft 31 Coaxially arranged in the inner barrel shaft 21 , the first rotor 4 is connected to the inner barrel shaft 21 , and the second rotor 5 is connected to the pulsator shaft 31 .

Abstract

The invention discloses a full-automatic washing machine comprises an outer tub, an inner basket, an impeller and a drive device, wherein the drive device comprises at least two rotors and at least one stator, one rotor is connected with an inner basket shaft, and the other rotor is connected with an impeller shaft; the drive device adopts a variable-frequency direct drive motor; the rotors, the stator, the inner basket shaft and the impeller shaft are coaxially arranged, the inner basket shaft is hollow, and the impeller shaft is arranged in the inner basket shaft; and during washing of the washing machine, the impeller and the inner basket rotate in the same direction or in reverse directions, or either of the impeller and the inner basket rotates, and the impeller and the inner basket rotate in the same direction at the same speed during spinning. According to the full-automatic washing machine, the two rotors are connected with the inner basket shaft and the impeller shaft respectively, the inner basket and the impeller are driven to rotate respectively by the two rotors, the weight, size and cost of a drive system are reduced to a great extent by means of the structure, and the transmission efficiency and stability are improved.

Description

technical field [0001] The invention relates to a washing machine, in particular to a fully automatic washing machine which uses a direct drive motor to directly drive a pulsator and an inner barrel to rotate. Background technique [0002] The rotation of the pulsator and the inner barrel of the traditional pulsator washing machine is that the motor drives the belt through the pulley to transmit the power to the deceleration clutch. The deceleration clutch converts the high speed of the motor into the lower speed required by the different washing processes of the washing machine through its internal gear structure. At the same time, according to 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 relat...
