Embodiment Construction

[0055] Hereinafter, regarding the first embodiment of the present invention, refer to Figure 1 to Figure 3 Be explained.

[0056] First, in figure 2 The middle figure shows the overall structure of the drum type washing machine, and the outer case 21 is used as an outer casing. In the front portion of the outer box 21 ( figure 2 In the substantially central portion of the middle right side), a laundry inlet and outlet 22 is formed, and a door 23 for opening and closing the inlet and outlet 22 is provided. In addition, an operation panel 24 is provided on the upper portion of the front portion of the outer case 21 , and a control device 25 for operation control is provided on the back side thereof (inside the outer case 21 ).

[0057] Inside the outer case 21, a water tank (tank) 26 is arranged. The water tank 26 is axially front and rear ( figure 2 Center right left) of the horizontal axis cylindrical shape, in this case, such as image 3 As shown, it is elastically ...

Abstract

Disclosed is a damper that obtains damping force through friction resistance resulting from the viscosity of a magnetic viscous fluid, and that is positioned on the outsides in the axial direction of a lower yoke and an upper yoke, a seal being disposed on one side (bottom) thereof and a seal being also disposed on the other side (top) thereof. As a result, the magnetic viscous fluid is sealed in both outer ends in the axial direction of a section that is filled with the magnetic viscous fluid, and the leakage thereof can be prevented. Also, as air is not led into the section that is filled with the magnetic viscous fluid, it is possible to favorably maintain the density of the magnetic viscous fluid in said section that is filled with the magnetic viscous fluid, and it is possible to prevent the occurrence of a decrease in damping force.

Description

technical field [0001] The present invention relates to a shock absorber, a washing machine, and a washing and drying machine using magnetic viscous fluid (MR fluid). Background technique [0002] Conventionally, for example, in a drum type washing machine, a water tank is located inside an outer case, a drum is located inside the water tank, and the drum is rotationally driven by a motor outside the water tank. In addition, the water tank is elastically supported by a suspension and installed on the bottom plate of the outer case, and the suspension is provided with a damper for attenuating the vibration of the water tank accompanying the vibration of the drum. [0003] Figure 29 An example of the above-mentioned shock absorber is shown, and includes a cylinder 1 and a shaft 2 inserted into the cylinder 1 as main components. Among them, the cylinder 1 is connected to a water tank (not shown) through a connecting member 3 provided at the upper end, and the shaft 2 is conne...
