Problems solved by technology

When the inner drum rotates, if the laundry is not evenly distributed in the inner drum but accumulates on one side of the inner drum, vibration and noise will be generated due to the eccentric rotation of the inner drum; Due to the eccentricity of the drum load and system resonance, etc., the pulsator washing machine vibrates greatly during high-speed dehydration, and at the same time produces large noise, which leads to poor user experience.
At present, the wave-wheel washing machine usually uses the suspension rod and the balance ring arranged on the top of the inner cylinder to reduce the vibration amplitude of the wave-wheel washing machine, but the vibration reduction effect is limited

Embodiment Construction

[0046] figure 1 is a schematic structural diagram of the inner tub 130 of the top-loading washing machine according to one embodiment of the present invention. see figure 1The inner cylinder 130 includes an upper cylinder wall 132 and a lower cylinder wall 133 made of rigid material, and a middle cylinder wall 134 connected between the upper cylinder wall 132 and the lower cylinder wall 133 and made of flexible material. The middle cylinder wall 134 is configured to deform under the eccentric load in the inner cylinder 130 when the inner cylinder 130 rotates at a high speed for dehydration, thereby reducing the eccentricity or degree of eccentricity of the load in the inner cylinder 130 .

[0047] Those skilled in the art can easily understand that for a pulsator washing machine, when the inner tub 130 rotates at a high speed for dehydration, eccentricity may occur due to uneven distribution of clothes in the inner tub 130 . For the top-loading washing machine with the inner...

Abstract

The invention provides an impeller washing machine and an inner barrel thereof. The inner barrel comprises an upper barrel wall and a lower barrel wall which are made of a rigid material, and a middle barrel wall which is connected between the upper barrel wall and the lower barrel wall and is made of a flexible material, wherein the middle barrel wall is configured to be deformed under an eccentric action of a load of the inner barrel when the inner barrel rotates at a high speed to dehydrate and spin-dry, so that when clothes at one side with the eccentric action in the inner barrel outward extrudes the inner barrel, the extruded part of the middle barrel wall is deformed and protrudes outward; meanwhile, washing water between the inner barrel and an outer barrel flows toward one opposite side through the protruding inner barrel, so that the washing water between the inner barrel and the outer barrel actively flows toward one side opposite to an eccentric direction, the balance of the impeller washing machine is actively adjusted, and furthermore, the eccentric amount of the load in the inner barrel is reduced.

Description

technical field [0001] The invention relates to a washing machine, in particular to a pulsator washing machine and an inner tub thereof. Background technique [0002] A washing machine is a device that uses electricity to wash clothes. Common pulsator washing machines on the market generally include a casing, an outer cylinder suspended and fixed in the casing by multiple (usually four) suspension rods, an inner cylinder rotatably installed in the outer cylinder, and a motor driving the inner cylinder to rotate. The pulsator washing machine performs a series of processes, such as washing, rinsing, and spinning, using the rotating motion of the inner tub. When the inner drum rotates, if the laundry is not evenly distributed in the inner drum but accumulates on one side of the inner drum, vibration and noise will be generated due to the eccentric rotation of the inner drum; Due to reasons such as drum load eccentricity and system resonance, the pulsator washing machine vibra...
