detailed description

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are intended to be illustrative of the invention and are not to be construed as limiting.

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 2, a washing machine 1 according to an embodiment of the present invention includes a cabinet 100, a rotary tub 200, and a pulsator 300.

The rotary tub 200 is rotatably disposed within the case 100 and includes a tub 210 and a drain passage 221. The drain passage 221 is disposed in the peripheral wall of the tub 210, and the liquid drawn from the tub 210 is discharged out of the tub 210 through the drain passage 221. The pulsator 300 is rotatably disposed within the barrel 210.

It should be understood here that "pull out" refers to discharge by centrifugal force when the rotary drum is rotated 200 revolutions, and is not limited to being thrown out through the upper end of the barrel.

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 provided without setting the tub, so that the water only needs to be filled in the rotating tub 200 without filling the tub, and the water-filling function can be achieved. Moreover, compared with the related art, the wave-flow washing machine adopting the double barrel structure is more water-saving.

Moreover, since the washing water flows only in the rotary tub 200, the problem that the double-barrel structure of the pulsator washing machine in the related art is easy to retain dirt between the inner tub and the outer tub can be avoided, and not only the retained dirt can be prevented from contaminating the laundry again, but also It can prevent the dirt from remaining in the inner and outer barrels for a long time and it is difficult to clean and cause bacteria to grow.

In addition, the washing machine 1 adopts a single barrel structure, so that the space between the rotating tub 200 and the box 100 is increased, so that the rotating tub 200 can be made larger, which is convenient for increasing the washing capacity of the rotating tub 200, thereby facilitating the improvement of the washing machine 1 Washing efficiency.

Further, the washing machine 1 adopts a single barrel structure, and does not need to be provided with a water tub structure. Compared with the washing machine of the related art, the design, manufacture and installation process of the water tub can be omitted, the design and manufacturing difficulty of the washing machine 1 can be reduced, and the washing machine can be conveniently reduced. The cost of 1 increases the production efficiency of the washing machine 1.

Specifically, by providing the drain duct 221, it is possible to avoid providing a drainage structure on the outer side of the tub body 210, reducing the size in the radial direction of the rotary tub 200, thereby facilitating reducing the radial size of the washing machine 1 while satisfying the use requirements, thereby The occupied space of the washing machine 1 is reduced, and the appearance of the washing machine 1 is improved.

That is to say, the washing machine 1 can realize the function of the original water tank and ensure the dehydration effect while canceling the water tank to simplify the structure, increase the capacity, reduce the dirt and bacteria growth, and save water.

Therefore, the washing machine 1 according to the embodiment of the present invention has the advantages of large capacity, environmentally friendly water saving, and less secondary pollution.

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

In some embodiments of the present invention, as shown in FIGS. 1-2, a washing machine 1 according to an embodiment of the present invention includes a case 100, a rotary tub 200, and a pulsator 300.

Specifically, as shown in FIG. 2, the drain passage 221 is provided in the peripheral wall of the tub 210. The liquid drawn from the tub 210 is discharged out of the tub 210 through the drain passage 221. In this way, the water drained from the rotary tub 200 can be taken out by the drain passage 221, and the water splashed in the rotary tub 200 can be prevented from splashing into other areas in the casing 100 to ensure the reliability of the washing machine 1.

Optionally, as shown in FIG. 1 to FIG. 2, the washing machine 1 further includes a balance ring 400 disposed at an upper end of the barrel 210 and connected to the upper end of the barrel 210. Thus, not only the balance ring 400 can be used to maintain the balance of the rotary tub 200 when the rotary tub 200 rotates, thereby reducing the vibration of the washing machine 1, preventing the rotating tub 200 from excessively shaking during operation, and allowing the water in the rotary tub 200 to pass through the drain passage 221 The discharge is performed to realize the drainage of the rotary tub 200.

Figures 1 - 2 show a washing machine 1 according to the invention. The upper end of the barrel 210 is dense with the balance ring 400 Seal the connection. In this way, not only the water splashed in the rotary tub 200 can be further prevented from splashing into other areas in the casing 100, but also the drainage efficiency during the drainage operation of the rotary tub 200 can be improved.

Specifically, the drainage channels 221 are several and spaced along the inner circumferential surface of the barrel 210, and the liquid drawn by the barrel 210 is discharged out of the barrel 210 through the drainage channel 221. The liquid thus ejected from the tub 210 can be uniformly discharged from the plurality of drain passages 221, facilitating the improvement of the drainage performance of the rotary tub 200.

Figures 1 - 2 show a washing machine 1 according to the invention. As shown in Figures 1-2, the barrel 210 is a cylinder having a uniform inner diameter. It should be understood here that the uniform inner diameter means that the inner diameters are substantially equal in the axial direction, and it is not excluded that the barrel 210 is provided with some uneven structure. In this way, the water in the rotary tub 200 can be prevented from being sprinkled when the rotary tub 200 is normally washed, and the water flow can be easily raised by the centrifugal force when the rotary tub 200 is drained, so that the water in the rotary tub 200 can be completely discharged.

Specifically, as shown in FIG. 1, the washing machine 1 further includes a water receiving tray 500, the water receiving tray 500 is disposed in the tank 100 and at least a portion of the water receiving tray 500 is disposed below the rotating tub 200, and the drain passage 221 is to be the barrel body. The liquid drawn out of 210 is directed to the water receiving tray 500. Specifically, the water receiving tray 500 supports the rotating tub 200, which may be a direct support or an indirect support. Thus, not only the water taken up by the rotary tub 200 can be collected by the water receiving tray 500, but also the water can be collected and guided, and the water receiving tray 500 can support other structures of the washing machine 1.

More specifically, as shown in FIG. 1, the washing machine 1 further includes a driving unit 600 for driving at least one of the rotating tub 200 and the pulsator 300, and the driving unit 600 is mounted on the water receiving tray 500. Thus, the drive unit 600 can be used to drive at least one of the rotary tub 200 and the pulsator 300 to rotate, thereby ensuring the reliability of the rotation of the rotary tub 200 and the pulsator 300.

Optionally, as shown in FIG. 1 , the washing machine 1 further includes a supporting shock absorbing assembly 700 . The supporting shock absorbing assembly 700 is disposed in the casing 100 and the water receiving tray 500 is supported on the supporting shock absorbing assembly 700 . This can reduce the displacement of the rotary tub 200 in the horizontal direction when rotating, and avoid the rotating tub 200 due to vibration. Collision with the case 100 improves the stability of the rotary tub 200 when rotating, and avoids collision noise.
