Description

Inner barrel assembly of washing machine and washing machine

Technical Field

The invention relates to the technical field of washing equipment, in particular to an inner barrel assembly of a washing machine and the washing machine.

Background

The existing washing machine, in order to avoid accumulating a large amount of thread scraps and dirt between the inner and outer barrels, designs the inner barrel as a washing barrel with the function of independently holding washing water during washing, and arranges a drainage structure for discharging the washing water during dehydration on the barrel wall of the washing barrel, so that the situations of flowing water between the inner and outer barrels, bacterial breeding on the outer wall of the inner barrel and the inner wall of the outer barrel and the like can not exist during washing operation of the washing machine. Meanwhile, the inner barrel of the washing machine has double effects of rotating washing and containing water, so that the washing machine does not need to be provided with an outer barrel, and the aim of expanding washing capacity is fulfilled.

However, in order to realize the function of containing water in the inner tub, the conventional pulsator washing machine generally has a drainage structure designed as follows:

the top of the inner tub is provided with a water outlet, so that when the washing machine executes a washing program, the water outlet is higher than the washing water level, and the inner tub directly forms a water container. In order to realize water drainage, the wall of the inner barrel is designed into an inverted cone shape with gradually increasing size from bottom to top, so that when the washing machine performs a dewatering process, the inner barrel rotates at high speed, water in the inner barrel is thrown outwards under the action of centrifugal force and moves upwards under the guidance of the inverted cone barrel wall until the water is discharged from a water outlet at the top of the inner barrel.

Although the washing machine can realize the function of draining water from the water-containing inner barrel, the drained water flow in the inner barrel moves upwards along the barrel wall under the action of centrifugal force and then flows out from the water outlet at the top of the inner barrel, and in the whole draining process, the drained water flow is attached to the barrel wall of the inner barrel and needs to overcome the self gravity of water when moving upwards, so that the rotating speed of the inner barrel is high in the draining process, and the power consumption is high in the draining process.

Meanwhile, the water outlet is arranged at the top of the wall of the inner barrel, and a circle of balance ring protruding towards the inside of the barrel is generally arranged at the position of the barrel opening of the inner barrel above the water outlet. In the drainage process of the washing machine, after drainage water flow moves upwards to the top along the wall of the barrel, the drainage water flow is influenced by interference of a balance ring arranged at the top of the inner barrel, so that part of water is remained in a gap space at the bottom of the balance ring and above a drainage outlet, and residual water is still remained in the inner barrel after the drainage process of the washing machine is finished.

In view of the above, the present invention is particularly proposed.

In this embodiment, the barrel wall 12 of the tapered inner barrel 1 is a frustum-shaped structure gradually narrowing from bottom to top, and since the discharged water flow of the tapered inner barrel 1 flows downward without overcoming its own gravity, the centrifugal force required for driving the flow is small, and therefore, the taper of the barrel wall 12 of the tapered inner barrel 1 can be designed to be a small value.

In this embodiment, the water outlet 4 is disposed on the barrel wall 12 of the conical inner barrel 1, and the valve plug 2 of the centrifugal valve 3 moves in a radial direction of the inner barrel 1 to move from outside to inside to correspondingly seal the water outlet 4 disposed on the barrel wall 12 of the inner barrel and move outwards to correspondingly open the water outlet 4; preferably, the impeller 9 is installed at the bottom in the inner barrel 1, and the water outlet 4 formed on the barrel wall 12 of the inner barrel is arranged at a height lower than that of the impeller 9, so as to ensure that the water in the inner barrel 1 can flow out from the water outlet 4 to the maximum extent, and further reduce the residual water in the inner barrel 1. Meanwhile, because the water outlet 4 is lower than the impeller 9, the residual water in the inner barrel 1 is positioned below the impeller 9, thereby avoiding the residual water from contacting with clothes in the inner barrel 1, improving the dewatering effect of the washing machine and obviously improving the use experience of users.

In this embodiment, the centrifugal valve 3 includes a valve plug 2, which can be moved along the radial direction of the inner barrel 1 and is correspondingly plugged at the water outlet 4; one end of the elastic element is connected with the outer side of the inner barrel 1, the other end is connected with the valve plug 2, and acting force for closing the water outlet 4 is applied to the valve plug 2.

Preferably, in the present embodiment, the valve plug 2 is made of an elastically deformable rubber material, so that when the valve plug 2 correspondingly closes the drain opening 4, the valve plug can be elastically deformed to effectively close the drain opening 4. Meanwhile, the cylindrical valve plug 2 can be arranged into a plurality of sections of cylindrical structures with different radial sizes, the radial sizes of the sections are sequentially enlarged from the axis of the inner barrel 1 to the outside, and the radial size of at least part of the sections is larger than the aperture of the water outlet 4.

Meanwhile, as shown in fig. 4 and 5, in this embodiment, a torsion spring 15 is disposed at a hinge joint of the swing link 14 and the inner barrel 1, and the torsion spring 15 provides an elastic force for driving the swing link 14 to swing toward the inner barrel 1, so as to push the valve plug 2 to move from outside to inside along the radial direction of the inner barrel 1 to seal the water outlet 4. Therefore, when the inner barrel 1 does not rotate or rotates below a set value, namely when the washing machine is in a washing state or a non-working state, the valve plug 2 correspondingly seals the water outlet 4 under a normal state, and the inner barrel 1 forms a sealed water container.

EXAMPLE III

Based on the first and second embodiments, the present embodiment further has the following technical features:
