Detailed Description of the Invention A: Industrial Application Fields: Problems relating to control devices for washing machines (01) Conventional technology The drive time of the rotor blades is automatically changed according to 11 (load) of the laundry, It is desired to wash the laundry uniformly regardless of load fluctuations, and for this purpose, a device that automatically or manually weighs the laundry and changes the driving time is disclosed in Japanese Patent Laid-Open No. 54-9.
On the other hand, as shown in Japanese Patent Application Laid-open No. 6267 and Japanese Patent Application Laid-Open No. 54-102063, the number of rotations of the rotor blade is detected, and even if the load fluctuates, the blade stops each time a predetermined number of times is reached, and the number of times of energization and interruption is controlled. A washing machine that will shift the process when the total count reaches a predetermined value! Tf! [In the case of the former, as proposed in No. 152303/1983, would the weight be automatically measured and then washed? It is necessary to change the basic configuration of the washing machine, such as forming a recess in a part of the 11FW. In the case of the 1L latter, even though the number of rotations is detected, the detection signal is only used for reversing, stopping, and advancing the upward stroke, and is not used for other controls.

When the comparison result is (N, >NL) and the washing process is executed, the rotary blade (7) stops and reverses each time a preset number of rotations is reached. The number of rotations is accumulated, and the accumulated value (NX) is always compared with the higher set number of rotations (NH). ), the washing process is completed, and the next rinsing process is started.

During the intermediate dehydration and final dehydration steps during the rinsing process, the drive motor (8) is rotated to the right by the drive circuit ■, and the rotor blade (
7) and the dehydration/washing sandbox (5) are rotated in one direction at high speed. At this time, a comparison is made between the detected number of rotations within the first MJ (tJ) and the lower set number of rotations (NL), and the same control as described above is performed.Especially, during dehydration, the number of rotations in the tank is The unevenness of the laundry may cause horizontal swaying, and in this case, the VC is often in the N-work (NL) state, so this is detected as a complete spin-start failure and is controlled.

The high set number of rotations in the dehydration process (NEJ does not need to be the same as the set number in the washing and rinsing processes. Compare this NH with the integrated NX?microcomputer σ&, CNH-N,). When this happens, the motor (81) is stopped, the drain stamp is closed, and the dewatering process is completed.If it is the last water extraction process, the entire process of the washing machine is completed.

In this way, each reversal time and stroke time are determined by the number of rotations of the rotary blade (7), so each time is long when the amount of laundry is large, and short when it is small, so that it is uniform regardless of the size of the load. It can be washed, and the detection signal of the number of rotations can also be used to detect abnormalities, making it possible to perform all abnormality notifications.

The above-mentioned washing paddle and dewatering operations are shown in the flowchart of FIG. 4. During the intermediate dehydration during the rinsing process and the final dehydration process, an abnormality is reported if the upper N is not closed. According to the invention, uniform washing or dehydration can be performed regardless of the size of the load, and abnormal noise can be detected based on the detection signal of the number of rotations. The device is what you can get.
