Embodiment 1

[0037] Such as figure 1 As shown, the present invention proposes a multi-tub washing machine, preferably a three-tub layout multi-tub washing machine layout form, which shows: the top layout of the multi-tub washing machine is a small drum washing machine, the middle layout is a drawer-type wavelet washing machine, and the bottom layout is For a large-drum washing machine, this embodiment provides invention protection for the type and location of the washing tubs in the three-tub washing machine.

[0038] The outer frame of the multi-tub washing machine is assembled with pressure riveting screws, the height meets the layout requirements of the three-tubs, the structural strength meets the vibration requirements of the three-tub operation, and the assembly form meets the process requirements, ensuring the structural strength of the whole machine when multi-tubs are in operation. , to ensure smooth transition of vibration during operation between multiple barrels, and centralize...

Embodiment 2

[0040] Such as figure 2 As shown in the structural layout of the multi-tub washing machine, the axial distance between the upper washing tub and the lower washing tub is too large. If a shock absorption system is arranged for a single washing tub, the shock absorption system will disperse the vibration of the upper washing tub and the lower washing tub. , because the position of the upper washing bucket is relatively higher than the center of gravity of the whole machine, when the vibration of the upper washing bucket is dealt with separately, it will generate forward, backward, left, right, upward and downward external forces when the upper bucket is running, which makes the During the operation of the multi-tub washing machine, there is a risk of tipping forward, backward, left, and right, which poses a great safety hazard.

[0041] Such as image 3 As shown, in view of the characteristics of the multi-tub washing machine, the upper washing tub and the lower washing tub are ...

Embodiment 3

[0051] Such as image 3 , as shown in 4, the damping structure above the upper and lower washing buckets is all designed with double hanging springs, and the suspension points are all higher than the axis (center of circle) of the cylinder of the washing bucket. One end of the hanging spring is connected to the outer bucket side of the washing bucket, and the other One end is connected to the whole machine frame of the multi-tub washing machine; the left and right symmetrical layout of the four hanging springs supports the upper and lower washing buckets in the whole machine frame; the left and right symmetrical layout makes the integrated structure of the upper and lower washing buckets run The vibration transmission in the middle is more stable, and the shock absorber at the bottom can counteract the vibration more reasonably, making the whole machine run more stably.

[0052] Through simulation experiments, according to the structural characteristics of multi-tub washing ma...

Abstract

The invention discloses a multi-drum washing machine. A second clothes treatment drum and a first clothes treatment drum which are arranged in the vertical direction are fixedly connected through a connecting frame. The lower portion of the first clothes treatment drum is supported on a supporting frame through multiple shock absorbers, and the multiple shock absorbers form different supporting angles relative to the horizontal plane. A second elastic part is arranged between the upper portion of the second clothes treatment drum and the supporting frame. By means of the above arrangement, thetreatment effect on vibration of the whole machine of the multi-drum washing machine is optimized, the washing drums are integrally connected through a rigid connecting structure, and vibration generated during running of the multiple drums is lowered; and it is ensured that vibration of the multiple drums is consistent under the working condition of the multi-drum washing machine, vibration energy can be treated in a concentrated manner, vibration transmission is more stable, different supporting angles are adopted for the multiple shock absorbers, and the shock absorption effect of the shock absorbers is obvious.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a multi-tub washing machine. Background technique [0002] Throughout the development history of washing machines, multi-tub washing machines have become the future development trend, but multi-tub washing machines have higher requirements for structure, appearance, and systems than ordinary washing machines. [0003] The installation form of the shock absorber at the bottom of the existing drum washing machine is mostly after the shock absorber is inclined at a certain angle, and the two ends are respectively connected to the frame of the washing machine and the outer barrel of the drum. However, the multi-tub washing machine has the characteristics of heavy weight, complex structure, and uncertain vibration of the whole machine. The existing shock absorption system of the washing machine cannot meet the requirements of the multi-tub washing machine. How to desig...
