Embodiment 1

[0038] figure 1 It is a schematic diagram of the structure when the drainage tank is connected to the suction pump, now combined figure 1 , image 3 , Figure 4 for further clarification.

[0039] When the washing machine starts to perform the dehydration program, the inner tub 3 of the washing machine starts to rotate slowly, opens the electromagnetic valve 12 connected to the water supply tank 41, and opens the water suction pump 10 connected to the drain tank 43.

[0040] Further, because the mass distribution of the laundry in the washing machine inner drum 3 is uneven, the centrifugal force is generated when the washing machine inner drum 3 rotates; at this time, the suspension spring 14 connecting the washing machine drum assembly and the washing machine shell 1 is generated by stretching or compressing The elastic force of the washing machine and the centrifugal force on the washing machine inner drum 3 cancel each other out, and because the suspension spring 14 is s...

Embodiment 2

[0048] figure 2 It is a schematic diagram of the structure when the drainage tank is connected to the air pump. The following is combined figure 2 , image 3 , Figure 4 for further clarification.

[0049] When the washing machine starts to perform the dehydration program, the inner tub 3 of the washing machine starts to rotate slowly, the solenoid valve 12 connected to the water supply tank 41 is opened, and the air pump 7 connected to the drain tank 43 is opened.

[0050] Further, because the mass distribution of the laundry in the washing machine inner drum 3 is uneven, the centrifugal force is generated when the washing machine inner drum 3 rotates; at this time, the suspension spring 14 connecting the washing machine drum assembly and the washing machine shell 1 is generated by stretching or compressing The elastic force of the washing machine and the centrifugal force on the washing machine inner drum 3 cancel each other out, and because the suspension spring 14 is ...

Abstract

The invention discloses a device for automatically regulating balanced solution, which comprises a servo plate and a fixed plate. The servo plate is coaxially installed to a rotation axis of a washingmachine inner barrel and rotates at the same angular velocity as the inner barrel of the washing machine. The fixed plate is flexibly installed with a washing machine shell. Inlet holes with the samenumber of balanced cavities are distributed on the servo plate. And the fixed plate is provided with three troughs which are a feed trough, an exhaust air trough and a drain trough. When the washingmachine dehydrates, the displacement caused by the imbalance of the inner barrel causes the relative displacement between the servo plate and the fixed plate, realizing the respective communication between inlet holes at different positions on the servo plate and the feed or drain trough on the fixed plate. By injecting or discharging the balanced solution into a designated balanced cavity with communicated pipes, the device can regulate automatically. At the end of dehydration, the device for automatically regulating balanced solution will empty the remaining balanced solution in each balanced cavity to complete the dehydration process.

Description

technical field [0001] The invention relates to the technical field of washing machines, and relates to a drum washing machine that automatically adjusts the quality of the balance liquid injected or discharged into the balance chamber at different positions during the working process, so as to automatically adjust the center of gravity of the inner drum and ensure the balance of dehydration. Background technique [0002] Washing machine vibration has always been a major problem for users and R&D personnel, especially when the drum type washing machine is dehydrating, and its vibration source mainly comes from the suspension system. [0003] As the core component of the drum washing machine, the suspension system mainly includes an inner cylinder, an outer cylinder, a drive motor, a counterweight, a suspension spring and a damper. Among them, the inner cylinder is a high-speed rotating structure, which is mainly connected with the outer cylinder of the washing machine throug...
