Description of the invention (8) (Please read the precautions on the back first (Fill in this page again.) Torque is represented by T ·, which is unlocked as an adjustment external force, showing the relationship between the frequency [Hz] as x2 and the transfer function ω / T [db], but it is a graph in Figure 6 ( graph) (logarithm of the horizontal axis). In Fig. 6, the transfer function on the vertical axis indicates the relative chirp when the peak value (frequency Π) of the transfer function is initially displayed as 0 [dB]. The frequency Π of the first positive peak 値 is the lowest-order natural vibration number, and the frequency f 2 of the first negative peak 値 is the lowest-order antiresonant frequency. Among them, in FIG. 3, when the frequency during acceleration coincides with the anti-resonant frequency f2, a good force transmission efficiency can be obtained. Fig. 7 shows the relationship between the frequency [Hz] of the force and the torque [N · m]. When the torque is reduced by the frequency f4, and this frequency f4 is set to 値 of the anti-resonant frequency f2, a high-efficiency force can be transmitted. The phenomenon of the washing machine can increase the vibration (vibration in the rotation direction) of the water tank 4. In Fig. 3, when the frequency at the time of acceleration is equal to the lowest-order natural vibration number Π, a reduction in vibration can be obtained. That is, when the frequency f4 in FIG. 8 is 値 of the lowest natural vibration number Π, the vibration can be reduced. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in this embodiment. In the third figure, the frequency during acceleration should be the same as the lowest anti-resonant frequency f2. The control device 19 can drive and control the washing machine motor by the motor driving circuit 23 1 0 makes the required time period t at the time of acceleration 1 / f 2. At this time, as shown in Fig. 8, the above required time limit is set in accordance with the determination result of the amount (weight) of laundry. In the eighth figure, "the firm washing course (j) (the water level is the weight of the water) of the laundry is calculated from the frequency f2 when the amount of laundry is 1 to 10 kg, and the required time period t obtained therefrom is shown. (l / f2). According to the first embodiment described above, in the vibration system, the acceleration time limit of the washing machine motor 10 is set to a specific frequency, that is, the lowest anti-natural frequency f2, thereby setting the vibration of the outer tank 4 to be increased. Acceleration time t 'has good power This paper size is applicable to Chinese National Standard (CNS) A4 specifications (21 × 297 mm) -11-Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 591153 A7 B7 V. Description of the invention (9 ). As a result, it is possible to effectively convert electrical energy into mechanical energy to obtain an improvement in cleaning efficiency. Especially according to this embodiment, it can be obtained by calculating a specific frequency, that is, the lowest-order inverse natural vibration number f2, By obtaining the acceleration time period t from the number of inverse natural vibrations, the acceleration time period t of the maximum vibration of the water tank 4 can be obtained, so that it is easy to improve the transmission efficiency. According to this embodiment, since the corresponding laundry load detection result The acceleration time period t of the washing machine motor 10 that generates the maximum vibration of the water tank 6 is set, so that the force transmission efficiency can be improved even if the amount of laundry is changed. Figs. 9 and 10 show a second embodiment of the present invention. In the water tank 4, a vibration sensor 25 that detects this vibration is installed, and the control device 19 can obtain the acceleration time limit t of the maximum vibration detected by the vibration sensor 25. That is, in the initial stage of laundry, the acceleration time limit For example, between 0.2 and 1.0 seconds, the drive motor 10 of the washing machine is changed every 0.1 seconds, the detection result of the vibration sensor 25 is measured, and the acceleration time period at which the maximum value is displayed is set as the acceleration time period t. According to this second implementation For example, since the motor acceleration time or deceleration time when the vibration detection result of the vibration sensor 25 becomes the maximum is set, it is possible to accelerate or decelerate control the washing machine motor to form a specific frequency, that is, the lowest-level anti-natural vibration number, and effectively transmit the force. As a result, it is possible to effectively convert electrical energy into mechanical energy and obtain an improvement in cleaning efficiency. The present invention can also be implemented as follows. Figure 3 Once the frequency during acceleration coincides with the natural vibration number Π, it can reduce its vibration, that is, the frequency f4 in Figure 7 is set to be natural once the paper size is set to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please (Read the notes on the back before filling out this page)

Description of the invention (10) The vibration can be reduced when the number of vibrations is π. Therefore, the acceleration time t of the washing machine motor 10 during washing can also be set to form the minimum vibration of the water tank 4. Therefore, its noise can be reduced. At this time, as shown in Fig. 11, the third embodiment of the present invention also sets the acceleration time t of the washing machine motor 10 when the water tank 4 forms a minimum vibration in accordance with the detection result of the amount of laundry. Thereby, even when the amount of laundry is changed, the noise is always kept small. In addition, a vibration sensor for detecting vibration of the water tank 4 may be provided, and a motor acceleration time limit when the vibration detection result of the vibration sensor is minimized may be set. Therefore, it is possible to accelerate or decelerately control the washing machine motor to form another specific frequency, that is, the lowest level of natural vibration number, which can reduce its noise. In addition, not only the motor acceleration time limit, but also the motor deceleration time limit (braking time limit), or only the motor deceleration time limit can be set to form the maximum or minimum vibration of the water tank 4. Alternatively, a vibration sensor can be provided to set the minimum vibration detection result. [Effects of the invention] According to the inventions in the scope of patent application Nos. 1 to 3, the energy efficiency can be improved for the maximum driving torque transmitted by the stirring body, and the inventions in the scope of patent applications Nos. 4 to 6 can reduce the noise.
