Embodiment 1

[0043] Such as Figure 1-3 As shown, the present embodiment provides an outer tub 100 of a washing machine. The inner wall of the outer tub 100 is provided with a lifting part 200 protruding inwardly relative to the inner wall of the outer tub 100 and extending upward from the lower part of the outer tub 100. The outer tub 100 The rotating water flow at the bottom climbs up to the upper part of the outer tub 100 along the lifting part 200 , and sprays into the inner tub along the cover of the outer tub 100 .

[0044] In this embodiment, a lifting portion 200 is provided on the inner wall of the outer tub 100 of the washing machine. The lifting portion 200 protrudes inwardly relative to the inner wall of the outer tub 100 and extends upward from the bottom of the outer tub 100. When the inner tub and / or the wave wheel of the washing machine rotate , driving the water flow to rotate, the rotating water flow at the bottom of the outer tub 100 can smoothly climb upward along the l...

Embodiment 2

[0073] This embodiment provides a washing machine with the outer tub of the washing machine as described in Embodiment 1. The washing machine includes an inner tub in which a pulsator is arranged, an outer tub cover is installed on the upper part of the outer tub, and the inner tub and / or the pulsator are driven to rotate The water flow climbs up to the upper part of the outer barrel along the lifting part on the inner wall of the outer barrel, and sprays into the inner barrel along the outer barrel cover.

[0074] The outer periphery of the outer tub lid is sealed and connected with the upper part of the outer tub. When washing, the motor drives the pulsator and / or the inner tub to rotate, and then drives the water flow to rotate. Under the centrifugal force generated by high-speed rotation, the water flow can rotate along the inner and outer tubs. flow, and climb upward along the lifting surface of the raised structure extending from bottom to top and inclined along the direc...

Embodiment 3

[0076] Such as Figure 4-5 As shown, this embodiment is a further limitation of Embodiment 2. A diversion structure 3 is arranged on the outer barrel cover, and the diversion structure 3 forms a diversion channel. The lifting surface of the raised structure is connected with the diversion structure correspondingly, and the water flow Climb up along the lifting surface and enter the outer barrel cover along the diversion structure. When reaching the outer barrel cover, the water flows into the diversion channel along the direction of rotation, and then sprays out from the narrowed water outlet of the diversion channel to form a dispersed spray water flow , spray on the clothes in the inner bucket.

[0077] The outer barrel cover includes a ring-shaped body, and a plurality of flow guide structures 3 arranged on the lower end surface of the outer barrel cover extend from the outer peripheral side of the body to the inner peripheral side, and are arranged in accordance with the r...

Abstract

The invention belongs to the field of washing machines, and discloses an outer drum of a washing machine, the washing machine and a control method. A lifting part which inwards protrudes relative to the inner wall of the outer drum and upwards extends from the lower portion of the outer drum is arranged on the inner wall of the outer drum, and the rotation water flow of the bottom of the outer drum upwards climbs to the upper portion of the outer drum along the lifting part and is sprayed into an inner drum along an outer drum cover. The lifting part comprises a protrusion structure which inwards protrudes relative to the inner wall of the outer drum, and the protrusion structure upwards extends along one side of the water flow towards the lower portion of the outer drum and is aslant arranged in the direction of the water flow. According to the outer drum of the washing machine, the lifting part is arranged on the inner wall of the outer drum of the washing machine, the lifting capacity of the water flow can be greatly improved without the need of replacing a high-power motor, and the spraying effect of the water flow is good.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to an outer tub of a washing machine, a washing machine and a control method. Background technique [0002] In the washing process of the pulsator washing machine, the laundry is immersed in the washing water and washed by means of continuous rotation or regular forward and reverse rotation of the pulsator. [0003] In order to enhance the washing effect, some washing machines on the market have added the function of waterfall washing or spray washing. Water channels are set on the inner wall of the inner tub of the washing machine. Spray on clothes to enhance washing effect. This method of setting water channels on the inner wall of the inner tub will not only reduce the effective storage space of the inner tub, but also reduce the number of clothes that can be washed by the user at a time. At the same time, the water output and intensity of the waterfall water flow in ...
