Problems solved by technology

[0003] However, since the water cavity is an annular cavity, when water enters from the water inlet, most of the water flow only passes through the water cavity near the water inlet and then flows out from the corresponding water outlet position, which cannot make the water flow uniformly from all positions of the water outlet. Outflow, the spray coverage area is small, that is, the comprehensive and effective spray effect cannot be achieved
In particular, when the water inlet pressure is insufficient or the water flow is slow, only the water outlet position corresponding to the water inlet position will normally discharge water, the spraying effect is very poor, and it is difficult to substantially improve the washing effect of clothes

Embodiment 1

[0048] An outer bucket cover, comprising an upper cover body 101 and a lower cover body 102, the upper cover body 101 and the lower cover body 102 are connected to form a water cavity 1, the inner peripheral wall of the water cavity 1 is provided with a plurality of water outlets, the water cavity 1 is connected to the The connecting part of the water inlet 3 is provided with a water uniform rib 2 extending along the circumference of the outer barrel cover 100. The water inlet is blocked by the water uniform rib 2 to divert to the water chamber 1 on both sides of the water inlet 3 and sprayed evenly by each water outlet. to the inner barrel.

[0049] A first water cavity 11 is formed between the water uniform rib 2 and the outer peripheral wall of the outer bucket cover 100, and the first water cavity 11 communicates with the water inlet 3; a second water cavity is formed between the water uniform rib 2 and the inner peripheral wall of the outer bucket cover 100 Cavity 12.

Embodiment 2

[0077] refer to image 3 , The difference between this embodiment and Embodiment 1 is that: the end points of the left and right sections of the ribs of the uniform water rib 2 are connected to form a full circle of ribs.

[0078] The uniform water rib 2 is arranged as a full circle in the water chamber 1. Those skilled in the art should know that the height of the part connecting the left and right section rib end points in the whole circle of ribs should satisfy: the water can enter through the first water chamber 11. to the second water chamber 12 so that the incoming water is sprayed out from the water outlet on the inner peripheral wall of the outer barrel cover 100 . see image 3 , the arrows in the figure indicate the flow direction of the water flow.

[0079] An outer bucket cover, comprising an upper cover body 101 and a lower cover body 102, the upper cover body 101 and the lower cover body 102 are connected to form a water cavity 1, the inner peripheral wall of th...

Embodiment 3

[0106] A novel water flow outer barrel cover, the outer barrel cover 100 includes an upper cover body 101 and a lower cover body 102 (such as Figure 4 As shown), the upper cover 101 and the lower cover 102 are provided with matching engaging parts, so that the upper cover 101 and the lower cover 102 engage and form a ring-shaped water cavity 1, the inner peripheral wall of the water cavity 1 There are a plurality of water outlet holes 4 on the top, and the outer barrel cover 100 is provided with a water inlet 3; water enters the annular water cavity 1 through the water inlet 3 and sprays into the inner barrel through the water outlet holes 4.

[0107] Each water outlet hole 4 is independently and evenly distributed on the inner peripheral wall of the water chamber 1;

[0108] Alternatively, the water outlet holes 4 are set as a plurality of water outlet hole groups 400 evenly distributed on the inner peripheral wall of the water chamber 1, and each water outlet hole group 400...

Abstract

The invention belongs to the technical field of washing machines, and in particular relates to an outer barrel cover and a washing machine. The outer barrel cover includes an upper cover body and a lower cover body, the upper cover body and the lower cover body are connected to form a water chamber, the inner peripheral wall of the water chamber is provided with a plurality of water outlets, and the water chamber and the water inlet are connected. The water-distributing ribs extending circumferentially along the outer barrel cover block the water inflow to the water chambers on both sides of the water inlet and spray evenly to the inner barrel from each water outlet. The water pressure in the water chamber of the outer barrel cover is balanced, which can achieve the effect of 360-degree uniform water discharge, improve the spraying effect of the washing machine, and better wash the clothes.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to an outer barrel cover and a washing machine. Background technique [0002] At present, washing machines with a spray function are generally equipped with a circulating water pump, through which the water at the bottom of the outer tub is drawn to the outer tub cover, and the water is discharged from the outer tub cover to form a spray-like water flow. Wherein, the outer barrel cover generally includes a water inlet, a water cavity and a water outlet, and water flows into the water cavity of the outer barrel cover through the water inlet, and the water accumulated in the water cavity is discharged from the water outlet for spraying. [0003] However, since the water cavity is an annular cavity, when water enters from the water inlet, most of the water flow only passes through the water cavity near the water inlet and then flows out from the corresponding water...
