At present, a common washing machine comprises an inner barrel and an outer barrel, wherein a plurality of small holes are arranged on the barrel wall of the inner barrel, when the washing machine is used for dewatering, due to the centrifugal force of high-speed operation, clothes are tightly attached to the barrel wall, water in the clothes enters the outer barrel through the small holes and is discharged out of the washing machine, and the purpose of dewatering is further achieved. Therefore, not only can a large amount of washing water be wasted, but also dirt and bacteria in the washing water are easy to accumulate between the inner barrel and the outer barrel, and the washing is not easy to cause secondary pollution to clothes.

In order to solve the problems, an inner barrel and an outer barrel are separated, and the inner barrel is used for storing water, so that the outer barrel is anhydrous. The sealing element is arranged at the position where the center of the bottom of the inner barrel is communicated with the outer barrel, so that the inner barrel can rotate relatively in a sealing mode, namely the outer barrel, therefore, the inner barrel is separated from the outer barrel, only water is contained in the inner barrel during washing, and water resources can be saved. However, the existence of the outer barrel also occupies more internal space, resulting in higher cost.

In order to increase the washing capacity of the washing machine, a larger inner tub is required, i.e., the height or diameter of the inner tub needs to be increased. If the inner tub has a larger size, an outer tub accommodating the inner tub and a cabinet accommodating the tub also need to be enlarged as the inner tub is enlarged.

The increase of the casing corresponding to the appearance of the washing machine is limited by the space of the area for installing the washing machine, the position for using the washing machine in a common user home is limited, the purpose of increasing the capacity of the washing tub by increasing the casing of the washing machine is unrealistic, and if the capacity of the inner tub is increased on the premise of not increasing the casing of the washing machine, the problem which puzzles a designer is solved.

The present invention has been made in view of this situation.

When the driving device 5 drives the inner tub 200 to rotate, the inner tub 200 and the fixed chassis 2 vibrate due to eccentricity caused by uneven distribution of the clothes. When vibration is transmitted to the deformation structure sleeved on the fixed chassis 2, the deformation structure disperses acting forces in all directions through deformation, and then the effect of reducing vibration of the washing machine in all directions is achieved.

The deformation structure is sleeved on the whole fixed chassis 2, encloses the area on one side of the fixed chassis 2 and is connected with the box body 1. That is to say, the periphery of the fixed chassis 2 is provided with a deformation structure which can disperse acting force through deformation, therefore, the vibration of the washing machine in all directions can be slowed down, and a better damping effect is achieved. The deformation structure cover is established on whole fixed chassis 2, like this, can also reduce extra damper's use, does not use extra damper even, and the wholeness is better, the installation of being more convenient for, has also further reduced the inside occupation space of washing machine simultaneously.

The water sealing assembly of the present embodiment keeps the drain hole 204 closed during the washing/rinsing process, prevents the washing water from entering the area between the inner tub 200 and the fixed chassis 2, keeps the water-free space between the tubs, and prevents the dirt from being bred and polluting the user's clothes. In the drainage process, the pull ring assembly moves along the axial direction of the inner barrel under the action of tensile force, the water sealing assembly is pulled, the drain hole 204 is opened, drainage is realized, and impurities such as silt in the washing process can be discharged, so that the cleanness of the inner barrel is kept.

The water sealing component of the water sealing device of the embodiment is mounted on the inner barrel 200 and rotates along with the inner barrel, so that the relative position of the water sealing component and the drain hole 204 is ensured to be fixed, and thus, when the drain hole 204 is closed/opened, only the water sealing component 500 needs to be pulled to move along the axial direction of the inner barrel, the positioning operation is not needed, and the water sealing device is simple and convenient and is easy to realize. The pull ring assembly 500 is sleeved outside the water sealing assembly and does not influence the water sealing assembly to rotate along with the inner barrel, the water sealing assembly can be pulled to move together only when the pull ring assembly pulls the water sealing assembly along the axial direction of the inner barrel, the drain hole 204 is opened to drain water, and the water sealing assembly is not blocked to rotate along with the inner barrel even when the pull ring assembly 500 pulls the water sealing assembly.

The telescopic structure is made of elastic materials and can elastically stretch and deform through the telescopic structure under the action of external force, and the deformation structure is a telescopic rubber belt or a telescopic rubber ring; alternatively, the elastic deformation may be performed by structural change, for example, the deformation structure is a folding expansion band/ring, such as a bellows. No matter which mode, the extending structure can reach the purpose that reduces vibrations with through deformation.

The fixing chassis 2 and the inner barrel 200 are coaxially arranged, and the telescopic structure and the fixing chassis 2 are coaxially arranged and are connected with the box body 1 while being fixed with the fixing chassis 2. Thus, the telescopic structure is more convenient to slow down the movement of the fixed chassis 2 and the inner barrel 200 in the direction of displacement caused by possible vibration, and the purpose of shock absorption is achieved.
