In this embodiment, the height of the second washing tub 3 is lower than that of the first washing tub 1, and during dehydration, the first washing tub 1 rotates at a high speed, and a part of residual moisture in the second washing tub 3 is discharged through a siphon pipe, and the other part is thrown out to the second washing space through the top of the annular tub body, so that the second washing tub 3 can normally realize dehydration.

The washing machine in this embodiment may be a washing machine without an outer tub, or a washing machine with an outer tub, and the first washing tub 1 is disposed inside the outer tub. In a specific embodiment, the annular tub body has an annular structure and is adapted to divide the first washing tub 1 into a first washing space having a cylindrical shape and a second washing space having an annular shape.

Specifically, during the washing process, the first pulsator 21 rotates in the first washing space, and the laundry rotates along with the first pulsator 21 and rubs against the inner wall of the second washing tub 3 and the first pulsator 21, thereby washing the laundry. The second pulsator 22 in the second washing space rotates, and the laundry rotates along with the second pulsator 22 and rubs against the inner wall of the first washing tub 1, the outer wall of the second washing tub 3, and the second pulsator 22, thereby washing the laundry.

In particular, the washing machine has three washing modes when the second washing tub 3 is installed. As shown in fig. 1 and 8, in the first washing mode, the pulsator shaft 25 is in the first position, the pulsator shaft 25 is connected to the first pulsator 21, only the first pulsator 21 is rotated, and the first washing space is washed; as shown in fig. 2 and 9, in the second washing mode, the pulsator shaft 25 is in the second position, the pulsator shaft 25 is connected to the second pulsator 22, only the second pulsator 22 is rotated, and the second washing space is washed; as shown in fig. 3 and 10, in the third washing mode, the pulsator shaft 25 is in the third position, the pulsator shaft 25 is connected to both the first pulsator 21 and the second pulsator 22, the first pulsator 21 and the second pulsator 22 rotate together, and the first washing space and the second washing space respectively perform washing. Preferably, in the third washing mode, the rotation directions of the first pulsator 21 and the second pulsator 22 are opposite, and when the second washing tub 3 is not installed to wash the laundry, the laundry is pushed away in the opposite direction by the first pulsator 21 rotating at a high speed in the process of being drawn close to the center under the action of the second pulsator 22, so as to achieve the effect of releasing the entanglement of the laundry, and the laundry is kneaded at the same time, so that the hand-rubbing type washing effect is realized, the wear of the laundry is small, and the washing effect is better.

The embodiment also discloses a control method of the washing machine, the washing machine is the above washing machine, and the control method of the washing machine comprises the following steps: one of the first and second washing spaces is controlled to perform a draining process and a dehydrating process first, and the other of the first and second washing spaces is controlled to perform a draining process and a dehydrating process after the dehydrated laundry is taken out. The washing water of the first washing space and the washing water of the second washing space are prevented from mutually circulating in the dehydration process, so that the pollution to the clothes is prevented, and the washing effect is poor. Alternatively, the user may control the dehydration process according to the actual operation of the washing machine.

In a preferred embodiment, the washing machine further comprises an alarm structure adapted to give an alarm after one of the first washing space and the second washing space performs the draining process and the dehydrating process first, to remind a user to take out the laundry.

Preferably, in this embodiment, the control method of the washing machine includes: the second washing space is controlled to firstly execute the drainage process and the dehydration process, the alarm structure gives an alarm after the dehydration is finished, and the first washing space is controlled to execute the drainage process and the dehydration process after a user takes out clothes between the first washing barrel 1 and the second washing barrel 3.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the utility model.
