Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. figure 1 A longitudinal sectional view of a front-loading washing machine according to a first embodiment of the present invention is shown.

[0019] In this figure, only the surroundings of the supporting mechanism and the basic constituent elements of the washing machine are shown as the main elements of the present invention, and other elements such as panel switches are omitted. Its main components include: an outer frame 1 made of thin iron plate; a base made of synthetic resin supporting the outer frame; a synthetic resin base that is elastically supported by a support mechanism 3 and is provided with a vibration sensor for detecting vibration on the outer periphery. Outer tub 4; a bellows 6 used to maintain watertightness with the outer frame in front of the outer tub; a glass door 7 embedded with the bellows 6 and arranged on the outer frame 1; rotata...

Abstract

The invention provides a drum-type washing device with the advantages of small space occupied, low vibration and low noise. The invention comprises an outer frame (1); and outer drum (4) supported inside an outer frame (1) through a support mechanism (3); a roller (5) which arranges a rotating shaft in such a way that the front side of the rotating shaft is higher than the inner side inside the outer drum (4); a driving unit for rotatablely driving the roller (5); a water-supplying and draining mechanism for supplying water into and draining water from the outer drum (4); and a controller forcontrolling the rotary driving of the roller (5) and the supplying water into and draining water from the outer drum (4). The invention is characterized in that the support mechanism (3) is provided with a main support mechanism having a spring and an oil shock absorber, and an auxiliary support mechanism (17 and 18) having a spring and an attenuation mechanism. The oil shock absorber is providedwith a hydraulic cylinder and a piston, and forms a structure which periodically generates an attenuation force according to the journey of the piston. The attenuation mechanism of the auxiliary support mechanism is arranged on the upper part of the outer drum so as to attenuate the vibration in the forward and the backward direction.

Description

technical field [0001] The invention relates to a drum-type washing machine in which a freely rotatable washing drum with a rotation axis line arranged horizontally is anti-vibrationally supported in an outer frame cabinet. The drum-type washing machine of the present invention also includes a drum-type washing and drying machine having a drying operation function. Background technique [0002] Patent Document 1 (Japanese Unexamined Patent Publication No. 2001-214951) describes a washing machine in which a hydraulic damper (oil damper) is provided between a frame constituting the outer contour of the washing machine and a drum rotatably arranged in the frame. ), increase the damping force generated by the hydraulic shock absorber to suppress the vibration of the drum when the vibration amplitude when the drum rotates is large, and reduce the damping force generated by the hydraulic shock absorber when the drum speed increases and the vibration amplitude decreases. Suppresse...
