Problems solved by technology

Once the balance system is not well designed, problems of resonance, displacement and loud noise will occur during the dehydration process, which will not only give users a poor experience, but even bring safety hazards. Therefore, the double-drum washing machine needs to be designed with a balance system to reduce the washing machine Eccentric displacement during operation

Embodiment 1

[0039] In this embodiment, the drive suspension assembly 10 of the double-drum washing machine needs to meet at least one of the following trim conditions after being balanced by the counterweight structure 5, and the specific trim conditions are as follows:

[0040] first trim condition

[0041] In the vertical up and down direction, the center of gravity of the suspension assembly 10 after the counterweight structure 5 is set is lower than the rotation axis of the first washing unit 1 and higher than the rotation axis of the second washing unit 2, and the center of gravity of the assembly is located in the first washing unit 1 and the second washing unit 2 form the middle position of the suspension assembly 10 to ensure the smooth operation of the whole machine. The above-mentioned rotation axis of the first washing unit 1 is the axis of the first inner tub 102 , and the rotation axis of the second washing unit 2 is the axis of the second inner tub 202 .

Embodiment 2

[0062] Such as Figure 1 to Figure 6 As shown, a double-drum washing machine is introduced in this embodiment, which includes a first washing unit 1 and a second washing unit 2 connected as a whole to form a suspension assembly 10, the suspension assembly 10 is connected with at least one shock absorber One end of the components 6 is connected, and the other end of each shock absorbing component 6 is connected with the shell 4 , so that the suspension assembly 10 is hoisted in the shell 4 . The resultant force of the external force exerted by each shock absorber 6 on the suspension assembly 10 is the elastic hoisting force, and the intersection point of the plane where the direction of the elastic hoisting force is co-located with the rotation axis of the first washing unit 1 and the rotation axis of the second washing unit 2 is the elastic center. The weight of the counterweight structure 5 is greater than the sum of the weights of the first motor 103 and the second motor 203...

Embodiment 3

[0074] Such as Figure 1 to Figure 6 As shown, a double-drum washing machine is introduced in this embodiment, which includes a first washing unit 1 and a second washing unit 2 that are connected as one and constitute a suspension assembly 10. The weight of the first washing unit 1 does not exceed the weight of the second washing unit. Weight of washing unit 2. By setting the weight of the second washing unit 2 at the lower part greater than the weight of the first washing unit 1 at the upper part, the center of gravity of the two connected washing units is set lower, so as to reduce the height of the center of gravity of the suspension assembly 10, thereby reducing the double drum The effect of the vibration noise of the washing machine. At the same time, during the operation of the double-drum washing machine, since the two washing units are connected, the two can provide the function of shock-absorbing counterweight to each other, and because the center of gravity of the a...

Abstract

The invention discloses a double-drum washing machine. The double-drum washing machine comprises a shell, a first washing unit and a second washing unit, wherein the first washing unit and the secondwashing unit are arranged up and down; the first washing unit and the second washing unit are connected to form a suspension assembly, and the suspension assembly is mounted in the shell through a damping mechanism; and counterweight structures are arranged on the first washing unit and / or the second washing unit and at least correspondingly matched with the weight of motors arranged on the rear parts of the first washing unit and the second washing unit. The counterweight structures are at least matched with the first motor and the second motor, so that drum openings of the first washing unitand the second washing unit of the suspension assembly provided with the counterweight structures cannot be excessively inclined to ensure that washing water contained inside cannot overflow from thedrum openings; and meanwhile the two motors are provided with counterweight structures in a matched mode to adjust the gravity center of the suspension assembly correspondingly, and thus the suspension assembly is in a leveled state to reduce vibration in the operation process of the washing machine.

Description

technical field [0001] The invention belongs to the field of washing machines, in particular to a double drum washing machine. Background technique [0002] A counterweight is a weight used to balance a moving part of a machine. [0003] Existing counterweights are generally manufactured by blow molding a hollow body of plastic material which is then filled with concrete or any other material with similar properties. For example: the counterweight is formed by two annular shells of plastics material adapted to enclose blocks of concrete or any other suitable material. Also, existing counterweights can also be formed in the shape of a continuous hollow ring with a U-shaped cross-section by a molded flange of plastics material, said flange also being provided with radial ribs adapted to receive and hold Installed on the washing unit of the washing machine to reduce the vibration during the operation of the washing machine. [0004] The double-drum washing machine in the pri...
