Embodiment Construction

[0018] figure 1 and figure 2 The supporting mechanism of the tub assembly 5 in the drum type washing machine 1 shown in one embodiment of the present invention. In the tub assembly 5 , the tub 3 is equipped with a rotary drum 2 , and the rotary shaft 2 a of the rotary drum 2 is supported in a bearing 68 provided on the back of the tub 3 , and the rotary shaft 2 a is also connected with the drum driving motor 7 . The tub assembly 5 is arranged in a tilted state where the front portion is upturned in the washing machine body 6 , and its weight is supported by two left and right vibration-proof damping components 70 arranged at the bottom of the washing machine body 6 . The back side of the water tub assembly 5 is due to the very large components such as the bearing 68 and the drum drive motor 7 being installed, so its center of gravity is positioned behind. The anti-vibration damping member 70 supports the tub assembly 5 from below the center of gravity on the front side. In...

Abstract

The present invention is a drum-type washing machine provided with a support mechanism capable of suppressing transmission of vibration generated when a rotary drum rotates to a washing machine body. Among them, the bucket assembly (5) with the rotating drum (2) inside the bucket (3) is supported from below by the anti-vibration damping member (70) at a position closer to the front than its center of gravity. The top of assembly (5) applies upper elastic force towards the front side by the 1st coil spring (71). In addition, the second coil spring (72) applies an elastic force toward the rear side to the bottom of the tub assembly.

Description

technical field [0001] The invention relates to a drum type washing machine which performs various operation steps such as washing, rinsing and dehydration by driving a rotating drum containing laundry to rotate. Background technique [0002] In the drum-type washing machine, since the rotating drum is set in the water tub so that its rotation axis is in the horizontal direction or has a certain inclination relative to the horizontal direction, when the rotating drum is loaded with laundry and then rotates, the laundry and water will It will be biased downward and will easily vibrate. Especially when the rotary drum is rotated at a high speed during the dehydration operation, if the laundry in the rotary drum gathers at an eccentric position, the tub in which the rotary drum is installed will vibrate greatly. In order to suppress the vibration generated when the rotating drum rotates, the bucket is generally supported by a very large anti-vibration damping member with a buf...
