Problems solved by technology

[0013] First, the viscoelastic member is placed on the bottom surface of the mass body, so the load of the mass body continuously acts on the viscoelastic member, which may cause damage and performance degradation of the viscoelastic member
[0014] Second, when the mass body vibrates in the horizontal direction, since the viscoelastic member absorbs the vibration using the shear stress (shear stress) acting in the left-right direction, there is a disadvantage that the attenuation ratio is reduced and the excessive vibration cannot be effectively absorbed
[0015] In the patent specification of the above-mentioned prior art, it is described that vi

Example Embodiment

[0042] Hereinafter, the laundry treating apparatus according to the embodiment of the present invention will be described in detail with reference to the drawings.

[0043] [Definition of terms]

[0044] First, terms described in the present invention are defined.

[0045] The excessive vibration (damped oscillation: damped oscillation (vibration: vibration) or transient oscillation: transient oscillation (vibration: vibration)) described below is defined as, when the drum in which the laundry is placed is rotated at an accelerated speed for rinsing or dehydration, when The vibration of the vibration displacement of the casing on the resonance point of the drum increases sharply.

[0046] Also, the normal vibration (steady-state oscillation: vibration: vibration) or continuous oscillation: continuous oscillation (vibration: vibration) explained below is defined as that during which the drum maintains the highest speed, at an almost constant Vibration Displacement Continuousl...

Abstract

The invention relates to a laundry treating apparatus which includes a cabinet, a drum accommodated in the cabinet, a tub accommodating the drum, and a dynamic absorber provided to absorb oscillationof the cabinet. The dynamic absorber includes a support plate coupled to the cabinet, mass bodies movably provided on the support plate, and sliders arranged between the mass bodies and the support plate, and the sliders can enable the mass bodies to perform reciprocating motion on the support plate while attenuating due to frictional force.

Description

technical field [0001] The present invention relates to a laundry treatment device. Background technique [0002] In the case of household electrical appliances such as washing machines and dryers with a rotating drum inside, as the rotation speed (rpm) of the drum increases, the laundry thrown into the drum, that is, the load eccentricity, produces horizontal displacement. Vibration-supporting force (vibration force). [0003] In particular, during the dehydration process, during the increase in the rotation speed of the drum, excessive vibration occurs in which the horizontal vibration displacement of the cabinet rapidly increases at the resonance frequency of the cabinet of the washing machine. Also, when the drum is kept constant at the highest speed, normal vibrations that repeat the same vibrations to some extent are generated. [0004] Due to such excessive vibration, a phenomenon in which the washing machine oscillates to the left and right occurs while the rotatio...
