- the vibration of the dewatering tank is not the same as the vibration at the time of low speed rotation at the beginning of rotation and the vibration at the stage after a certain amount of time for starting the rotation. Therefore, an optimum vibration detection means is required according to the state of vibration. That is, since the vibration mode differs depending on the rotation speed of the dewatering tank, a suitable vibration detection technique for the vibration mode is required.
- An object of the present invention is to provide a technique for effectively detecting abnormal vibration in a dehydrating apparatus that exhibits different vibration modes depending on the number of rotations.

- switching is performed by the third acceleration detection means that is orthogonal to the horizontal direction and also perpendicular to the vertical direction. It is possible to output with.
- the vibration mode means the state of vibration or the type of vibration.
- an acceleration sensor may be fixed to the bearing, and a change in acceleration in the axial direction and a change in acceleration in the direction orthogonal to the axial direction may be detected. Because the modes of vibration are different, the outputs of the acceleration sensor in two directions will be signals of different forms. In the present invention, the processing efficiency suitable for the different vibration modes is added to the output of the acceleration sensor that detects the vibration of the different modes, thereby enhancing the detection efficiency of the vibration. Furthermore, in order to switch the output of the acceleration sensor in two directions, it is not necessary to separately provide a rotational speed detection means such as an encoder by utilizing the output of the third acceleration detection means derived from the rotational direction of the cylinder. It is possible to perform the necessary detection only with the acceleration sensor.

- This vibration mode is detected as a vibration characterized by the amplitude in the rotation axis direction of the dewatering tank. For the sake of convenience, this vibration is referred to as longitudinal vibration.
- Lateral vibration is a vibration that appears when the dehydration tank is rotating at a low speed, but the acceleration is so large because the cycle is long. Therefore, the output of the acceleration sensor that detects the lateral vibration has a relatively small value. It becomes.
- the longitudinal vibration is a vibration that appears when the dehydration tank is rotating at a high speed, so the amplitude is relatively small, but the acceleration accompanying the vibration is large. The output of the acceleration sensor is relatively large. It becomes a value.

- step S406 If any abnormal vibration occurs during dehydration at the maximum rotation speed, the determination in step S406 is NO, and the processing in step S410 and subsequent steps is performed.
- step S410 it is determined whether the current Y-axis side output value is a specific frequency value, for example, about 8 to 10 Hz. If the current frequency value is less than the specific frequency value, the process proceeds to step S415. Stop the rotation of the dewatering tank 108. If the current Y-axis output value is equal to or greater than the specific frequency value, the process proceeds to step 411 and the Y-axis side output value becomes the specific frequency value. Processing is performed to reduce the number of rotations to a specific number of rotations (for example, 400 rotations). Then, the dropped rotational speed is maintained for a predetermined time (step S412), and it is determined again whether the Z-axis side output is less than or equal to the second voltage (step S413).
- a specific frequency value for example, about 8 to 10 Hz.
- step S 415 is executed to stop the washing tub and dewatering tub 108.

Proceed to step S12, otherwise return to the previous step of step S412.
- the elapsed time determined in step S414 is set to a length of about 1.5 to 3 times the elapsed time determined in step S409.

That is, after step S403, water injection is performed, and the washing and drying tank 108 is rotated a plurality of times in the forward and reverse directions. By doing this, the bias of the laundry is eliminated. After this, the processing of step S401 and subsequent steps is executed again. By doing this, dehydration can be resumed automatically.
