Embodiment Construction

[0035] Below, refer to figure 1 as well as figure 2 One embodiment of the present invention will be described.

[0036] First, in figure 2 The whole structure of the drum-type washing machine is shown in the figure, and the outer box 21 is used as a casing. On the front part of the outer box 21 (at the figure 2 A door 22 for putting in and taking out the laundry is formed in a substantially central portion of the door 22 , and a door 23 for opening and closing the door 22 is provided in the door 22 . Moreover, the operation panel 24 is provided in the upper part of the front part of the outer case 21, and the control apparatus 25 for operation control is provided in the back side (in the outer case 21).

[0037] A water tank 26 is arranged inside the outer case 21 . The water tank 26 has an axial direction in the front-rear direction ( figure 2 The water tank 26 is elastically supported on the bottom plate 21a of the outer box 21 by a pair of left and right (only on...

Abstract

The present invention provides a drum-type washing machine and a method for manufacturing a hanger bracket with a damper, in the damper by using magnetoviscous fluid to absorb vibration of a sink, assembly is easy, and structure is simple. A damping force of the damper (41) is controlled by changing viscosity coefficient of the magnetoviscous fluid (69) by energizing a coil (55). A cylinder (42) of the damper (41) is provided with the coil (55) coiled to a bobbin (56), and then provided with a holding member (60) for accepting a magnet yoke (65), a sealing member (64) and a bearing (63), a shaft (43) is inserted across, and the damper (41) is assembled by filling the magnetoviscous fluid (69) between the shaft (43) and the bobbin (56), between the shaft (43) and a magnet yoke (52), and between the shaft (43) and the magnet yoke (65). Then, a spring is mounted between the holding member (60) and a spring base (71a) of the shaft (43) to assemble the hanger bracket (27).

Description

technical field [0001] The present invention relates to a drum-type washing machine using a magnetorheological fluid as a damper for absorbing vibration of a water tank, and a method of manufacturing a suspension having the damper. Background technique [0002] Conventionally, drum-type washing machines have dampers for absorbing vibrations of the drum and the vibration of the water tank that are rotated by accommodating laundry in the water tank as a suspension that supports the water tank on the bottom plate of the outer case. As such a damper, a damper using a magnetoviscous fluid (Magnetic Fluid...MR fluid) whose viscosity varies depending on the strength of a magnetic field is known as a working fluid (for example, refer to Patent Documents 1 and 2). [0003] here, image 3 It is a figure which shows an example of this damper, and has a cylinder block 1 and a shaft 2 as main components. Among them, the cylinder block 1 is attached to a water tank (not shown) through a ...
