Impeller type fully-automatic washing machine and driving device thereof

Abstract

The invention provides an impeller type fully-automatic washing machine. The impeller type fully-automatic washing machine comprises a chassis (2) and a water-accommodating bucket (7), wherein the water-accommodating bucket (7) is arranged in the chassis (2); a dehydrating bucket (6) is arranged in the water-accommodating bucket (7); an impeller (8) is arranged at the bottom of the dehydrating bucket (6); a driving device (10,11) is arranged below the dehydrating bucket (6); the driving device comprises a motor (11) and a transmission device (10); the transmission device (10) is arranged between the dehydrating bucket (6) and the motor (1), is directly driven by the motor to drive the dehydrating bucket (6) and the impeller (8) to rotate along the opposite direction and comprises one or two groups of planetary reduction gears. The gears are directly driven by the motor to distribute a plurality of groups of power in a speed-reducing mode, wherein the impeller is driven by one group of power to rotate; and the dehydrating bucket is driven by the other one group of power to rotate, so that the washing and dehydrating requirements of the fully-automatic washing machine are met through simple transmission. The impeller type fully-automatic washing machine has a simple structure and high reliability and greatly reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a washing machine and its transmission device, in particular to a pulsator type fully automatic washing machine and its transmission device. Background technique [0002] The pulsator-type automatic washing machine drives the pulsator to rotate through the deceleration of the clutch to generate pulsed water flow. During washing, due to the centrifugal force, the water rises along the inner side of the bucket, and the water in the center of the bucket is strongly sucked downward, forming a strong and powerful downward flow. The rubbing water flow makes the clothes roll up and down freely with the water flow. On the other hand, the contact between the pulsator and the washing liquid increases, which can effectively transfer energy in the washing liquid with low degree of staining. When washing, the laundry motor drives the planetary gear reducer in the clutch through the belt drive. After the reducer is decelerated, the wave whee...

AI Technical Summary

Problems solved by technology

[0008] When the above-mentioned washing machine dehydrates the clothes, the intertwined clothes are often biased against the side wall of the dehydration bucket 6 by the centrifugal force, so that the water tub outside the dehydration bucket of the washing machine vibrates from side to side due to the unbalanced load. In particular, The motor 11 is biased on one side of the water tub 7. When the center of gravity of the entire water tub 7 is not on the central axis, the vibration of the washing machine will be more serious.

[0009] There are two ways to solve the above-mentioned vibration problem in the above-mentioned washing machine: 1. Add a balance block on the other side of the motor to ensure that the center of gravity of the bucket is on the central axis; 2. Use elastic suspenders 5 with different pressures to adjust the four groups The force of the spring is so that the center of gravity of the bucket is adjusted on the central axis, but the vibration damping effect of these methods is not ideal
