Problems solved by technology

Or even if there is a water dividing rib on the outer barrel cover, the direction of the water flow is not considered, and the diversion effect is not good. It is also necessary to increase the motor power to achieve a better spray cleaning effect, resulting in a waste of resources
[0005] In addition, the outer bucket cover with water-guiding ribs on the lower end is directly installed on the upper part of the outer bucket and extends to the balance ring to spray into the inner bucket. The shape of the water flow will be affected during the rotation of the inner bucket and the balance ring, which is not conducive to water flow. Flow along the diversion ribs, affecting the spray effect

Embodiment 1

[0050] Such as Figure 1-10 As shown, the present embodiment provides an outer barrel cover 1 of a washing machine. The outer barrel cover 1 has an annular cavity 103, and the outer periphery of the annular cavity 103 is provided with a water inlet 7, and the water inlet 7 is located on the outer barrel of the outer barrel. Inside, after the water flow is lifted along the inner wall of the outer barrel, it enters the annular chamber 103 through the water inlet 7, and sprays into the inner barrel.

[0051] The outer tub cover 1 of this embodiment has an annular cavity 103, and the water inlet 7 of the annular cavity 103 is on the outer periphery and inside the outer tub of the washing machine. After the outer bucket cover is installed on the upper part of the outer bucket, the inner side extends to contact the balance ring, so the annular cavity 103 can isolate the water flow from the rotating inner bucket and the balance ring. In this way, under the rotation of the inner tub ...

Embodiment 2

[0071] Such as Figure 6-Figure 13 As shown, this embodiment is a further limitation of the embodiment. A washing machine outer barrel cover 1 is provided, and a flow guide structure is also provided in the annular cavity, and the flow guide structure extends from the outer peripheral side of the annular cavity to the inner peripheral side. The diversion channels 4 with narrowed water outlets are respectively formed between the adjacent diversion structures 3, and the water flow enters the diversion channels 4 after being lifted and is sprayed from the water outlets to the inner tub.

[0072] The upper cover body of the outer barrel cover 1 of the washing machine is ring-shaped, and the outer periphery of the outer barrel cover 1 is sealed and connected with the outer barrel. When washing, the motor drives the pulsator and the inner barrel to rotate, and then drives the water flow to rotate. Under the action of centrifugal force generated by high-speed rotation, the water flow ...

Embodiment 3

[0090] Such as Figure 6 to Figure 8 As shown, the present embodiment is a further limitation of the second embodiment. The extended guide rib 32 of the present embodiment includes a straight guide section 32-1 and an arc guide section 32-2, and one end of the straight guide section 32-1 It is connected with the end of the circumferential guide rib 31, and the other end is connected with the arc-shaped guide section 32-2. connect.

[0091] The straight guide section 32 - 1 and the arc guide section 32 - 2 extending the guide rib 32 can be integrally formed or seamlessly connected. The arc-shaped diversion section 32-2 bends and extends from the outer peripheral flanging 5 to the inner periphery, and when the water flow rotates and climbs under the rotation of the inner barrel, it can enter the diversion channel 4 along the curved arc-shaped diversion section 32-2, The diversion effect is good. The straight-line diversion section 32-1 connects the arc-shaped diversion sectio...

Abstract

The invention discloses an outer drum cover of a washing machine, the washing machine and a control method. The outer drum cover of the washing machine is provided with an annular cavity, a water inlet is formed in the periphery of the annular cavity and located in an outer drum, and after lifted along the inner wall of the outer drum of the washing machine, water flow enters the annular cavity through the water inlet and is sprayed into an inner drum. According to the outer drum cover, it can be achieved that the water flow is lifted along the inner wall of the outer drum of the washing machine and sprayed into the inner drum without additionally arranging a water pump and increasing the power of a motor; moreover, the water flow entering the annular cavity can be prevented from being affected by the rotation of the inner drum and a balance ring, so that the water flow is smoother, the dispersion of the water flow is good, spraying is conducted more evenly, and the spraying effect is better.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to an outer bucket cover of a washing machine, a washing machine and a control method. Background technique [0002] At present, washing machines with a spraying function are generally provided with a circulating water pump, through which the water at the bottom of the outer tub is drawn to the upper outer tub cover for spraying. However, installing a circulating water pump not only increases the cost, but also increases power consumption when used, wasting resources and energy. [0003] The eddy current washing machine does not need to be equipped with a circulating water pump. During washing, the motor drives the pulsator and the inner tub to rotate, and then drives the water flow to rotate. Under the centrifugal force generated by the high-speed rotation, the water flow can be lifted along the inner and outer tubs to reach When the outer barrel is covered, it is block...
