Problems solved by technology

[0004] However, in the above-mentioned washing machine, when the increase in vibration is not detected by the sensor unit, the control of the damper is not performed.
That is, the control of the damper is post-control based on the premise that the vibration is detected by the sensor unit, so the vibration and / or noise suppression effect is not sufficient, and it has become a major cause of large vibration especially during dehydration.

[0032] exist figure 2 In the illustrated drum type washing machine (hereinafter simply referred to as the washing machine 10), an outer case 11 formed as an outer casing has, at its front portion ( figure 2 The laundry entrance 12 is formed in a substantially central part of the middle right side), and a door 13 for opening and closing the entrance 12 is provided. An operation panel 14 is provided on the upper portion of the front portion of the outer case 11 , and a control device 15 for operation control is provided on the back side thereof (inside the outer case 11 ). In addition, on the bottom plate 11a of the outer case 11, a temperature detection device (the temperature detection part 67 described later, refer to Figure 4 ).

[0033] Inside the outer case 11, a water tank 16 in the shape of a horizontal axis cylinder is disposed. Tank 16, its central axis points to the front and rear direction ( figure 2 center, left and right), and is elastically supported on th...

Abstract

A washing machine is provided with a damping device and a control means. The damping device is a device for damping the vibration of a tank using a cylinder having a working fluid sealed therein. The working fluid is a functional fluid, and the control means controls the viscosity of the functional fluid. In a dewatering process of the washing machine, the control means variably changes the damping force of the damping device by changing the viscosity of the functional fluid according to the rotation of the rotating tank.

Description

technical field [0001] The present invention relates to a washing machine and a drying machine. Background technique [0002] Conventionally, washing machines have been provided with a shock absorber that supports a water tank arranged in an outer case (outer shell) between the outer case and the water tank, and absorbs the vibration of the rotating tank (inner tank). Even the vibration of the sink. In such a damper, it is known to use a magnetic viscous fluid (MR fluid) whose viscosity changes with the strength of a magnetic field as a working fluid (for example, refer to Patent Document 1). [0003] In this damper, for example, a cylindrical member (cylinder) is filled with magnetic viscous fluid, an electromagnet is arranged around the cylinder, and the viscosity characteristic of the magnetic viscous fluid is changed by controlling the current of the electromagnet with a controller. Furthermore, in the water tank, a sensor unit is provided as a vibration detection devi...
