Embodiment 1

[0049] A washing machine without water between the inner and outer tubs of this embodiment, comprising: an outer tub;

[0050] The inner barrel is rotatably arranged in the outer barrel;

[0051] And the pulsator is rotatably arranged at the bottom of the inner barrel;

[0052] During the washing / rinsing process, the inner bucket contains water, and there is no water between the inner bucket and the outer bucket;

[0053] The barrel wall of the inner barrel is provided with a sand discharge channel for discharging silt and other sundries: during the dehydration process of the washing machine, the water flow washes away silt and other sundries through the sand discharge channel.

[0054] In the washing machine without water between the inner and outer barrels of the present invention, the sand discharge channel is arranged on the inner barrel to discharge the silt and other sundries on the clothes during the dehydration process.

[0055] Further, the setting of the sand disch...

Embodiment 2

[0069] Such as image 3 and Figure 4 As shown, in the washing machine without water between the inner and outer barrels of this embodiment, a sand discharge cover 3 is installed on the barrel wall of the inner barrel, and a sand discharge channel is formed between the sand discharge cover 3 and the inner barrel wall;

[0070] The sand inlet of the sand discharge passage is arranged at the bottom of the inner tub and below the pulsator 5, and the sand discharge outlet 2 of the sand discharge passage is arranged near the top of the inner tub and higher than the highest water level of the washing machine.

[0071] In this embodiment, the sand discharge cover 3 is installed on the barrel wall of the inner barrel, and there is a certain gap between the sand discharge cover 3 and the barrel wall of the inner barrel to form a sand discharge channel. In this way, the structure and manufacturing method of the inner barrel do not need to be changed, which is easy to implement, low in ...

Embodiment 3

[0102] This embodiment provides a control method for a washing machine with no water between the inner and outer tubs as described above:

[0103] The washing machine executes the washing / rinsing program. The pulsator rotates at a speed of ω1 to stir the water flow to wash clothes. The water flow cannot flow out of the sand discharge port of the sand discharge channel at a speed of ω1;

[0104] The washing machine executes the dehydration program, and the pulsator and the inner tub rotate synchronously at a speed of ω2 to dehydrate the clothes. When the water flow is at a speed of ω2, the sediment and other sundries are washed away from the sand discharge port of the sand discharge channel;

[0105] Wherein, the rotational speed ω1 is smaller than the rotational speed ω2.

[0106] The control method of this embodiment realizes the sand discharge requirement by setting the rotation speed ω1 during washing / rinsing and the rotation speed ω2 during dehydration, which is simple, co...

Abstract

The invention provides a washing machine without water between the inner and outer barrels and its control method. The washing machine comprises: an outer barrel; an inner barrel rotatably arranged in the outer barrel; and a pulsator rotatably arranged at the bottom of the inner barrel; During the rinsing process, the inner barrel contains water, and there is no water between the inner barrel and the outer barrel; a sand discharge channel for discharging debris such as sediment is arranged on the barrel wall of the inner barrel: during the washing / rinsing process of the washing machine, The water flow cannot flow out from the sand discharge channel. During the dehydration process, the water flow washes away sediment and other sundries and is discharged from the sand discharge channel. In the washing machine without water between the inner and outer barrels of the present invention, the sand discharge channel is arranged on the inner barrel to discharge the silt and other sundries on the clothes.

Description

technical field [0001] The invention relates to the technical field of laundry devices, in particular to a washing machine with no water between inner and outer tubs and a control method thereof. Background technique [0002] Such as figure 1 As shown, the existing washing machine includes a casing 16 , an outer tub 15 and an inner tub 14A arranged in the casing 16 , and the inner tub 14A is rotatably arranged in the outer tub 15 . In order to realize the dehydration function of the clothes, the wall of the inner tub 14A is covered with dehydration holes, so that when the clothes are washed, the washing water will flow between the inner tub 14A and the outer tub 15 through the dehydration holes, and this part of the washing water cannot Being fully utilized leads to waste of water resources. [0003] In addition, due to the problem of water storage between the inner barrel 14A and the outer barrel 15, it will cause dirt to grow on the outer wall of the inner barrel 14A, th...
