detailed description

The technical solutions of the present application will be described below with reference to the accompanying drawings and specific embodiments.

The present invention provides a washing machine outer tub cover 10, as shown in FIG. 1 to FIG. 5, the washing machine outer tub cover 10 includes a cover wall 1, a cover plate 2 with a hole in the middle, and a cover wall 1 connected to the cover wall 1 and has a ring structure. The water retaining rib 6, the cover wall 1, the cover 2 and the water retaining rib 6 are integrally formed, and the cover 2 is located between the cover wall 1 and the water retaining rib 6.

Referring to FIG. 3 and FIG. 4, the lower end surface of the cover plate 2 is circumferentially surrounded by a plurality of ribs 3 arranged in a spiral shape, and each of the ribs 3 is connected to the first end side wall of the cover wall 1 with water blocking. The sheet 4, the water stop 4 and the cover 2 form an arc-shaped water outlet 5. When the inner tub of the washing machine rotates at high speed together with the pulsator, the washing water rises along the annular gap between the outer tub and the inner tub to the cover wall 1 and the cover 2, and is blocked by the retaining rib 3, and the washing water is along the speed at a certain speed. The retaining rib 3 flows to the water retaining piece 4 and is sprayed into the inner tub through the water outlet 5.

In this embodiment, the lower end surface of the cover plate 2 has a rim 21 extending downward from the edge of the hole. The rim 21 has an annular structure, and the rim 21 is provided with an opening 22 corresponding to the position of the water stop sheet 4. The opening 22 is curved. The structure and the water blocking sheet 4 and the cover plate 2 together form a water outlet 5. Through the provision of the above-mentioned rim 21, the washing water rising along the circumferential gap between the outer tub and the inner tub can be blocked by the rim 21 and sprayed to the inner tub through the water outlet 5, so that a large jet force can be achieved to meet the jetting. Requirements on clothing.

Moreover, when the washing water is sprayed to the inner tub through the water outlet 5 through the arc-shaped water outlet 5 formed between the arcuate opening 22, the water stop sheet 4 and the cover plate 2, the washing water will exhibit a waterfall-like spray state. The waterfall-like spray is more beautiful, and on the other hand, the washing water can be uniformly sprayed onto the clothes, thereby uniformly drying the clothes and improving the washing effect.

In this embodiment, the second end of the retaining rib 3 is connected to the cover wall 1. The first end of the retaining rib 3 away from the cover wall 1 extends to the rim 21, and the structure is arranged to enable the wash water to be completely blocked. 3 blocked, and finally all sprayed out through the water outlet 5. Moreover, the structure of the above-mentioned rib 3 is arranged, and the rib 3 is combined with the rim 21 and the cover 2 to form a closed space, so that the washing water can only be sprayed out through the water outlet 5, thereby further improving the utilization rate of the washing water. Moreover, it does not cause the washing water to splash above the cover 2, which improves the user experience.

The retaining ribs 3 of the plurality of arc-shaped structures are evenly distributed along the circumferential direction of the cover plate 2 at the lower end surface of the cover plate 2. In an embodiment, each of the retaining bars 3 projects two arcs toward the cover plate 2, and the outer arcs a (shown in FIG. 3) projected by the adjacent two retaining bars 3 are away from the end of one end of the cover wall 1. The angle between the tangent lines is α=360°/N, where N is the number of the retaining ribs 3, and the arc on the side opposite to the outer arc a is the inner arc. By the setting of the angle α, the shape of the washing water discharged through the water outlet 5 can be made more beautiful, and can be more uniformly sprayed onto the clothes, which is both aesthetic and practical. In this embodiment, the above α may be selected as 30°, 45° or 60°, etc., and may be set according to different models and the size of the cover 2 .

In this embodiment, the thickness of the second end of the retaining rib 3 connecting the cover wall 1 is greater than the thickness of the first end of the retaining rib 3 away from the cover wall 1. When the washing water rises along the annular gap between the outer tub and the inner tub to the outer tub cover 10 of the washing machine, the position of the retaining rib 3 connecting the cover wall 1 is first contacted, and the flow rate is relatively large, and the retaining rib 3 is needed at this time. The thickness of the second end of the connecting cover wall 1 is set to be large enough to block the washing water, and then the washing water can be completely sprayed from the water outlet 5 until the retaining rib 3 is provided with the water stop 4 away from the first end of the cover wall 1. Inner barrel.

In this embodiment, the water retaining rib 6 and the cover wall 1 have the same diameter. As shown in FIG. 5, an overflow port 7 is disposed outside the water retaining rib 6, and the overflow port 7 is provided with a plurality of vertically arranged grilles. 72, an overflow passage 71 is formed between the adjacent two grilles 72, and the overflow passage 71 communicates with the space above the water retaining rib 6 and the cover 2. When there is water overflowing above the cover 2, if the water has a size similar to a coin or the like, since the grill 72 is vertically disposed, and the gap between the adjacent two grilles 72 is small, the cover can be The debris on the plate 2 is blocked at the upper portion of the outer lid 10 of the washing machine to prevent debris from flowing into the drain valve of the washing machine through the overflow passage 71, thereby causing damage to the drain valve of the washing machine, and preventing the waste valve from being caused by coins and the like. Blockage, affecting the drainage function of the drain valve.

The present application also provides a fully automatic washing machine. As shown in FIG. 6, the fully automatic washing machine includes the above-mentioned washing machine outer tub cover 10, and further includes an inner tub 20, an outer tub 30 and a balance ring 40, which are disposed on the outer tub cover 10 of the washing machine. There is a buckle, the outer lid 10 of the washing machine can be fastened to the outer tub 30 by a snap, and the cover 2 of the outer lid 10 of the washing machine is placed above the balance ring 40 of the washing machine.

The fully automatic washing machine provided by the present application can reasonably utilize the washing water rising along the circumferential gap between the outer tub 30 and the inner tub 20 through the outer tub cover 10 of the above-described washing machine, and can avoid the occurrence of splashing of water splash.
