A washing machine 1 according to an embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 7, a washing machine 1 according to an embodiment of the present invention includes a cabinet 100, a rotary tub 200, and a water receiving tray 400.

The rotary tub 200 is rotatably disposed in the casing 100, and a water outlet 211 is provided on the peripheral wall and/or the bottom wall of the rotary tub 210. The water receiving tray 400 is disposed in the cabinet 100 and at least a portion thereof is located below the rotating tub 210. The water receiving tray 400 is used to support the rotating tub 200, which may be directly supported or indirectly supported. When the rotary tub 210 is rotationally dehydrated, the liquid in the rotary tub 210 can be discharged from the water outlet 21 to the water receiving tray 400 and discharged from the water receiving tray 400. The side peripheral wall of the water receiving tray 400 extends upward and is higher than the water outlet 211, and the height difference h between the upper edge of the side peripheral wall of the water receiving tray 400 and the outer bottom surface A of the rotating tub 210 is less than half of the height H of the rotating tub, that is, h<H/2.

The washing machine 1 according to the embodiment of the present invention adopts a single barrel structure, that is, only the rotating tub 200 is disposed without setting the tub, so that the water in the rotating tub 200 during washing is more water-saving, and the structure is simplified, the capacity is increased, and the capacity is reduced. Dirt and bacteria breed.

Also, by providing the water receiving tray 400, and the height difference h between the upper edge of the side peripheral wall of the water receiving tray 400 and the outer bottom surface A of the rotating tub 210 is smaller than half the height H of the rotating tub 210, preferably, the water receiving tray On the side wall of 400 The height difference h of the outer bottom surface A of the rotary tub 210 is 1/10-1/3 of the height of the rotary tub 210. Of course, it is not limited to this range, and may be set lower or no side peripheral wall is provided, as long as the water receiving tray is provided. The 400 can collect the water discharged from the water outlet 211. Compared with the conventional water tank, the water receiving tray 400 has a greatly reduced height and a smaller space, and the barrel cover is omitted, so that the material is greatly reduced and the cost is reduced. Moreover, the gap between the rotating tub 210 and the case 100 is greatly improved, and the same volume of the washing machine 1 can increase the capacity by increasing the diameter and height of the rotating tub 210.

In addition, the side peripheral wall of the water receiving tray 400 extends upward and is higher than the water outlet 211, so that when the water in the rotating tub 210 is discharged from the water outlet 211, all of the water can be flowed into the water receiving tray 400 to prevent water from rotating in the rotating tub 210. The lower end of the splash spilled out.

Therefore, the washing machine 1 according to the embodiment of the present invention has the advantages of large capacity, water saving and pollution-free, low cost, less material consumption, high space utilization rate, and good dewatering effect.

Thereby, the dewatering effect can be improved at the same time in the case where the water tank is eliminated to simplify the structure, increase the capacity, reduce dirt and bacteria growth, and save water.

Moreover, the water guiding cover 220 is attached to the rotating tub 210, and it is not necessary to provide an additional structure on the casing 100 or to provide the casing 100 as an internal and external double-layer structure to realize water guiding during the dehydration process, so that the casing 100 is Material selection is no longer limited, for example, materials such as sheet metal can be used to greatly enhance the appearance.

The water outlet 211 may be disposed on the peripheral wall of the rotary tub 210, or may be disposed on the bottom wall of the rotary tub 210, or the water outlet 211 may be disposed on the peripheral wall and the bottom wall. Specifically, the water outlet 211 is disposed on the peripheral wall of the rotating tub 210, which The water guiding cover 220 covers the water outlet 211, and the lower end of the water guiding cover 220 is only connected to the peripheral wall of the rotating tub 210, which facilitates the sealing of the water guiding cover 220 and the peripheral wall of the rotating tub 210. Of course, the water outlet 211 in the present invention can also be disposed on the bottom wall of the rotating tub 210, and the water guiding cover 220 covers the water outlet 211, which is beneficial to improve the dehydration efficiency during dehydration, has good dehydration effect, and can effectively reduce water from the water. Splash in the water outlet 211. The water outlet 211 is disposed on the peripheral wall and the bottom wall, which is advantageous for sealing the water guide cover 220 and the peripheral wall of the rotary tub 210, and is also advantageous for improving the dehydration efficiency during dehydration, and can effectively prevent water from splashing out of the water outlet 211.

Therefore, the washing machine 1 according to the embodiment of the present invention has the advantages of large capacity, water saving and pollution-free, low cost, good dewatering effect, beautiful appearance, and favorable sealing.
