Problems solved by technology

Because the existing balance ring is generally only set on the upper end of the inner barrel, the bottom of the inner barrel cannot realize the function of correcting the deviation during the dehydration process, which makes the dehydration process noisy and the running stability is poor

Embodiment 1

[0029] combine figure 1 and figure 2 As shown, a balancing ring assembly at the bottom of the inner tub includes an inner tub bottom cover 3, a flange 4 and at least one balancing ring 5, the inner tub bottom cover 3 is generally installed at the bottom of the washing machine inner tub, and the flange 4 is set The bottom of the inner barrel bottom 3 is fixedly connected with the inner barrel bottom 3. The balance ring 5 is arranged between the inner barrel bottom 3 and the flange 4. The center of the balance ring 5 is located on the rotation axis of the inner barrel bottom 3. The balance ring 5 is filled with a balance medium. For example, it can be filled with liquid to form a liquid balance ring, or balls and silicone oil can be added to form a ball-type balance ring. Centrifugal force can be used to counteract the vibration of the inner barrel caused by gravity imbalance.

[0030] Preferably, the flange 4 is provided with an annular groove structure 8 that cooperates wit...

Embodiment 2

[0035] Such as image 3 As shown, in order to improve the balancing effect of the balancing ring 5 , there are multiple balancing rings 5 ​​in this embodiment, which are stacked up and down along the axial direction of the balancing ring 5 . Specifically, the inner cavity of the balance ring 5 can be divided into a plurality of independent chambers by setting a partition layer in the balance ring 5, or a plurality of balance rings 5 ​​with the same diameter can be welded together to achieve the same Effect.

Embodiment 3

[0037] Such as Figure 4 As shown, the difference between the present embodiment and the second embodiment is that the plurality of gimbals 5 are arranged side by side along the radial direction of the gimbals 5. This arrangement takes up little space and does not affect the safety gap between the inner and outer barrels. , specifically, the inner cavity of the balance ring 5 can be divided into a plurality of independent chambers by setting a partition layer in the balance ring 5, or a plurality of balance rings 5 ​​with different diameters can be welded together to achieve the same Effect.

Abstract

The invention relates to an inner barrel bottom balancing ring assembly, comprising: an inner barrel bottom cover, a flange plate arranged at the bottom of the inner barrel bottom cover and fixedly connected with the inner barrel bottom cover, and at least There is a balance ring. The center of the balance ring is located on the rotation axis of the bottom cover of the inner cylinder, and the balance ring is filled with a balance medium. The present invention also relates to a washing machine equipped with the balance ring assembly at the bottom of the inner tub, which also includes an inner tub, the bottom cover of the inner tub is fixedly connected to the bottom of the inner tub; The balance ring is arranged coaxially with the balance ring located between the bottom cover of the inner barrel and the flange. The balance ring of the present invention is closer to the center of rotation, so that when the washing machine starts dehydration, the balance medium for correcting deviation is located closer to the axis of the inner tub, which effectively improves the balance of the inner tub of the washing machine at the initial stage of dehydration, and reduces the vibration and noise of the washing machine.

Description

technical field [0001] The invention relates to laundry dehydration equipment, in particular to an inner tub bottom balancing ring assembly applied to a washing machine and a washing machine equipped with the inner tub bottom balancing ring assembly. Background technique [0002] Existing pulsator washing machines mainly include: an outer tub, an inner tub, a gimbal, a pulsator, the bottom of the inner tub and a flange. Among them, the inner barrel bottom, the inner barrel bottom cover, and the flange are collectively referred to as the inner barrel bottom assembly. The balance ring of the existing pulsator washing machine is located on the upper end of the inner tub, and is detachably connected to the inner tub by bolts. The inside of the balance ring is filled with salt water to balance the vibration caused by the unbalanced load on the upper part of the washing machine when dehydrating. The bottom cover of the inner tub is set by welding At the bottom of the inner barrel...
