Embodiment Construction

[0046] First refer to figure 1 , which shows the washing machine 1 to which the spin attenuation device of the present invention is applied. The washing machine 1 is of a front loading type, having a front loading door 2 for introducing or removing laundry washed in a drum 12 . The washing machine 1 includes an outer case 3 . from figure 2 A schematic arrangement of the damping system of the oscillating unit 10 of the washing machine 1 can be seen in . The damping system comprises at least one spring 17 and at least one rotary damping device 18 . The oscillating unit 10 comprises a barrel 11 housing a drum 12 rotated by the action of a motor 14 and a transmission mechanism for rotating the drum 12 by the motor 14, comprising a fan belt 15 functionally coupled to the drum 12 and Pulley 16. In this arrangement for a damping system, an oscillating unit 10 is coupled to a frame 13 , said oscillating unit 10 being suspended by means of springs 17 and supported by means of rot...

Abstract

Rotary damping device for electrical household appliance, such as a washing machine 1 or a dryer, where the device 18 comprises an arm 20, 21 articulated according to a principal articulation axis 23, 26, 28, optionally by means of at least one principal rotational damper 40, particularly a friction damper. The device 18 is characterized in that it comprises at least one secondary body 30 articulated with respect to an secondary axis of articulation by means of a secondary rotational damper 41, particularly a friction damper, and being connected, in particular mechanically, to an arm 20, 21 of the device 18.

Description

technical field [0001] The invention relates to the technical field of damping devices of domestic appliances or of oscillating units of household appliances such as washing machines or dryers. In these home appliances, the oscillating unit includes a washing tub, a drum rotated in the washing tub by an action of a motor. The tub is attached to the frame of the household appliance by means of at least one damping device in order to damp vibrations or noise caused by the rotation of the drum inside the tub during operation of the appliance. Background technique [0002] Axial attenuators (also known as linear attenuators) for household appliances such as washing machines or dryers are well known. The axial damping device comprises two support arms connected to each other with axial displacement freedom. The axial damping device is arranged in the household appliance such that the support arm is respectively articulated to the frame (frame hinge) and to the oscillating unit ...
