Inner tub structure for washing machines

Abstract

The invention relates to the technical field of washing machines, in particular to an inner tub structure for washing machines. The inner tub structure comprises an inner tub; the inner bottom of the inner tub is provided with fastening grooves; a pulsator retainer is fitted to the fastening grooves and comprises a pulsator retaining rotary plate connected to the inner bottom of the inner tub; a ring is arranged between the pulsator retaining rotary plate and the inner bottom of the inner tub; a locking device is connected to the lower end of the pulsator retainer through a shaft; a base is arranged below the locking device; a dynamic balance device is arranged between the base and the locking device. During washing, the pulsator retaining rotary plate is driven by an inner shaft to rotate clockwise, and then the inner tub rotates anticlockwise with the pulsator retaining rotary plate; as the cycle goes on, washing is achieved. During dewatering, the inner rotates with the pulsator retaining rotary plate so as to achieve dewatering. Through the use of the dynamic balance device used for supporting the inner tub and disposed at the lower end of the locking device, the inner tub of the washing machine is protected from knocking or unbalance, shock is effectively damped and the service life of the washing machine is prolonged.

Description

Technical field [0001] The invention involves the field of washing machine technology and specially involves the inner barrel structure of a washing machine. Background technique [0002] The washing machine uses the motor to rotate the rotary cylinder and the current to achieve its washing process, drift process and dehydration process in turn. It is a kind of stirring on them after putting the washing water and washing lamps into the rotary cylinder.Use the device to be washed between the washing water and the rotary tube. [0003] However, when washing machines in existing technologies, when washing and dehydration, the tide rotation of the pulsator of the pulsator and the overall rotation of the pulsator and the inner barrel overall clockwise rotating was achieved through the action of clutch device and belt.Large loads and waste of energy. In addition, during the dehydration process, because the motor drives the inner barrel rotation, the pulsator rotates with one.life. Inv...

Problems solved by technology

[0003] However, when the washing machine in the prior art is washing and dehydrating, the conversion between the clockwise rotation of the pulsator and the counterclockwise rotation of the pulsator and the inner tub is achieved through the action of the clutch device and the belt, so the structure is complicated and the motor bears The load is large, which wastes energy. In addition, during the dehydration process, since the motor drives the inner tub to rotate, the pulsator rotates with it, and the inner tub of the washing machine will be drummed or unbalanced with the outer tub or base, which will affect the use of the washing machine. life
