Referring to fig. 1-4, one embodiment of a water deflector blade according to the present utility model is shown. The water-shifting blades are arranged on the inner wall surface of the inner cylinder of the drum washing machine and are used for driving the clothes to ascend in an arc line, so that the clothes fall under the action of gravity to form a beating effect. The water-shifting blades are provided with a plurality of water-shifting blades, are uniformly distributed along the circumference of the inner wall surface of the inner cylinder, and are parallel to the axial direction of the inner cylinder in the length direction.

FIG. 1 is a perspective view of a water deflector blade; fig. 2 is a schematic view of the internal structure of the water-repellent blade.

Referring to fig. 1 and 2, the water deflector includes a water deflector body 100 and a lateral isolation rib 200.

The bottom of the water deflector body 100 is open with an inner cavity.

The transverse isolating ribs 200 cross the inner cavity of the water-repellent blade body 100 along the length direction of the water-repellent blade body 100 to divide the inner cavity into two chambers A: the first chamber and the second chamber have the same structure. The water-poking blade bodies 100 on the side surfaces of the two chambers are respectively provided with water inlets 131, and the water-poking blade bodies 100 on the tops of the two chambers are respectively provided with spray holes 112.

When the washing machine works, the inner cylinder rotates to drive the water-shifting blade to the lowest point in the cylinder, water flow can enter the inner cavity from the water inlet 131 of the water-shifting blade body 100, and water flow at the bottom is stored; when the inner cylinder rotates to a high point, water flows are sprayed out through the water spraying holes to form a spraying effect, and the surface of the clothes is washed.

The inner cavity of the water-poking blade body 100 is divided into two chambers A by the transverse isolating ribs 200, when the inner cylinder rotates clockwise, water enters from one side to one side, and when the inner cylinder rotates anticlockwise, water enters from the other side to the other side, so that forward and reverse rotation bidirectional spraying is realized.

According to the water-shifting blade, the water inlet holes 131 and the spraying holes 112 are formed, water flow can enter the water-shifting blade through the water inlet holes 131, the height of the water-shifting blade is increased, so that the water flow flows out of the corresponding spraying holes 112 again to form a water spraying effect, the surface of clothes is washed, the washing effect of the washing machine is improved, and the structure is simple; meanwhile, by arranging two chambers and arranging water inlets 131 on two sides respectively, forward and reverse rotation bidirectional spraying can be realized.

In this embodiment, the paddle further includes a plurality of vertical spacer ribs 300. The vertical isolation ribs 300 longitudinally penetrate through the inner cavity of the water-poking blade body 100 along the width direction of the water-poking blade body 100, are arranged to cross the transverse isolation ribs 200, divide the two chambers A into a plurality of chamber units a respectively, and each chamber unit a is at least communicated with one water inlet 131 and one spraying hole 112. In this embodiment, the vertical spacer bars 300 and the horizontal spacer bars 200 are vertically disposed, and each chamber unit a is respectively connected to one water inlet 131 and one spray hole 112. By dividing the large chamber into small chamber units, the speed of the ejected water flow can be increased, and the spray washing effect can be improved.

Further, the spacing distances between the respective vertical barrier ribs 300 are equal, so that the respective chamber units are equal in size. The water flows respectively enter each chamber unit through the water inlet holes 131 and are then sprayed out from the spraying holes 112 of each chamber unit, so that the uniformity of the sprayed water flow can be ensured.

In addition, the vertical spacer 300 also plays a role of a reinforcing rib, and can improve the strength of the water-repellent blade.

In the present embodiment, the water inlet 131 is disposed near the lower portion of the water deflector body 100. When the inner cylinder rolls to enable the water-poking blades to rotate to the lowest position, water flow at the bottom of the inner cylinder conveniently enters the inner cavity through the water inlet 131 at the lower part.

Referring to fig. 1, the water deflector body 100 in the present embodiment specifically includes a top plate portion 110, side plate portions 120 located at both sides, a vertical hemming portion 130 formed to extend downward along the bottom edge of the side plate portion 120, and end plate portions 140 located at both ends. The side plate portion 120 is preferably an arc-shaped structure recessed inward. The water inlet 131 is formed on the vertical flange 130.

A fixing part is provided in the inner cavity of the water-repellent blade body 100, and the fixing part is used for being fixed with the inner wall surface of the inner cylinder of the drum washing machine. The fixing portion in this embodiment includes four fastening structures 400 and two screw columns 500, and after the water-shifting blade is pre-positioned and installed with the inner cylinder through the four fastening structures 400, the water-shifting blade is fastened on the inner cylinder through the fastening pieces such as screws and the screw columns 500 in a matching manner.

The top of the water-repellent blade body 100 is provided with a groove 111 arranged along the length direction of the water-repellent blade body 100, and the spray holes 112 are formed in the groove 111. Because the width of the top plate 110 of the water-poking blade body 100 is narrower, the grooves 111 can play a role in enhancing strength, the spray holes 112 are convenient to set, and meanwhile, the clothes can be prevented from directly contacting with the water-poking blade body 100, the spray water flow is blocked, and the spray washing effect is affected.

The water inlet 131 is preferably a strip or oval hole, so that the inner cavity of the water-stirring blade can be filled with water rapidly. In other embodiments, the water intake speed may be increased by increasing the number of water intake holes 131.

The water-poking blade in the embodiment is of an integrated structure, and is simple in structure and low in cost.

The utility model also comprises a drum washing machine, wherein the inner wall surface of the inner barrel of the washing machine is provided with a plurality of water-shifting blades, the water-shifting blades are provided with the water inlet holes 131 and the spray holes 112, water flow can enter the water-shifting blades through the water inlet holes 131, the height of the water-shifting blades is increased, and then the water flow flows out of the corresponding spray holes 112 to form a water spraying effect, so that the surface of clothes is washed, and the washing effect of the washing machine is improved; meanwhile, by arranging two chambers and arranging water inlets 131 on two sides respectively, forward and reverse rotation bidirectional spraying can be realized.
