Washing machine and outer drum thereof

Abstract

The invention discloses a washing machine and an outer drum thereof. The outer drum is provided with four hanger hanging parts, at least one hanger hanging part is of a double-hanging-loop structure, and each double-hanging-loop-structure hanger hanging part is provided with two hanging loops which are adjacently arranged on the circumference of the outer drum. The hanger hanging parts are separated into four groups on the circumference of the outer drum and uniformly distributed along the circumference of the outer drum, and every two oppositely arranged hanger hanging parts are positioned in the same radial direction of the outer drum. All hanger hanging parts can be of the double-hanging-loop structures, or parts of the hanger hanging parts are of the double-hanging-loop structures while the other parts of the hanger hanging parts are of single-hanging-loop structures, and each single-hanging-loop-structure hanger hanging part is provided with a hanging loop. Each hanging loop comprises a base arranged on the outer wall of the outer drum in a protruding manner and a hanger hanging hole formed in the base, and the hanger hanging holes of the hanger hanging parts are formed in the same circumference. By improving structures of the hanger hanging parts of the outer drum, deflection resistance of the outer drum is enhanced, vibration attenuating and damping effect of the washing machine is enhanced, and the outer drum is simple in structure and convenient to mount.

Description

technical field [0001] The invention relates to a washing machine, in particular to an outer tub of a washing machine and a washing machine with the outer tub. Background technique [0002] The structure of the existing fully automatic washing machine includes: a shell that forms the appearance of the washing machine; an outer tub that is suspended and fixed by a support member and used to accommodate washing water is provided inside the shell; it is rotatably installed inside the outer tub, and An inner barrel with an agitator at the bottom; a driving motor installed on the lower side of the outer barrel and used to generate the driving force of the agitator and the inner barrel; a power transmission device for selectively providing the driving force of the driving motor to the agitator and the inner barrel; The drainage device is installed on the lower part of the outer tub and is used to discharge the washing water contained in the outer tub to the outside. The outer tub ...

Problems solved by technology

However, the vibration and noise reduction effect of this kind of vibration-damping components is not good, especially for large-capacity washing machines above 10kg.

This is because there are a lot of clothes in the large-capacity washing machine. When the clothes are washed in the inner tub of the washing machine, the clothes are prone to eccentricity. During the dehydration operation, especially when the clothes in the inner tub are eccentric, the outer tub will swing during operation. , when the eccentricity of the clothes is large, the swing range of the outer tub will increase. When the self-correcting ability of the washing machine is exceeded, the washing machine will automatically hit the stop switch to stop the dehydration operation, or hit the cabinet, resulting in abnormal noise

[0007] Many manufacturers overcome the above-mentioned defects by changing the elastic coefficient of the damping components as follows: 1. Increase the rigidity coefficient of each spring, such as changing the material or thickening the spring, although the vibration damping effect can be achieved during washing and low-speed dehydration, However, at high speed, the damping force cannot be reduced, resulting in large vibrations and unable to operate normally; 2. Increase the length of each spring. This method needs to change the height of the outer tub and the space occupied in the radial direction, thereby increasing the washing machine. volume
