Abstract

The invention discloses a suspension device of a drum type washing machine and a method for avoiding resonance of the drum type washing machine. The method adjusts the modulus of elasticity of the elastic member before the drum reaches the resonance speed in the dehydration cycle of the washing machine. If the rotation speed of the drum exceeds the resonance speed, this method returns the modulus of elasticity of the elastic member to the original state, thereby preventing resonance from being generated.

Description

technical field [0001] The invention relates to a suspension device of a drum-type washing machine and a method for avoiding resonance, in particular to a suspension device for a drum-type washing machine and a method for avoiding resonance of a drum-type washing machine, which is adjusted during the operation of the drum-type washing machine Modulus of elasticity of the suspension to avoid resonance. Background technique [0002] figure 1 is a sectional view depicting a conventional drum type washing machine. [0003] Such as figure 1 As shown, the traditional drum type washing machine includes: a casing assembly 1 forming the appearance of the washing machine; a tub 2 installed in the casing assembly 1; a drum 3 rotatably installed in the tub 2; a motor 4 of the drum 3; and a spring 5 and a damper 6 for damping vibration transmitted to the tub 2 . [0004] The cabinet assembly 1 includes: a cabinet 7 forming opposite side surfaces and a rear surface of the drum type wa...
