(Hereinafter, referred to as a microcomputer). In addition to the signal input from the water level sensor 15, signals from the ball IC 40, the key input unit 29 of the operation panel 6, the safety switch 30, and the like are input to the microcomputer 27.
In addition, the nonvolatile storage means 41 is connected and stores the operating state. The stored contents include time from power-on to power-off, washing time in the operation process, number of rinses,
Dehydration time and measurement data of each sensor.
Next, measurement data that can be stored will be described. Actual measurement data of load sensor Actual measurement data of cloth surrounding sensor Actual measurement data of dehydration start-up sensor Total number of rotations of motor since dehydration start Number of rotations during dehydration Water supply flow rate sensor -Actual measurement data-Water supply time when the pump function is used Total usage time and number of times of use from the time of purchase The measurement method of the above data is as follows. ~
By using the Hall IC 40 installed on the motor, the number of rotations of the motor can be measured, and the data of each sensor can be measured by using the measured value. It can be used as data. The number of pulses output from the Hall IC 40 when the pulsator 17 is rotated for a certain number of times before the water supply is measured. The pulsator 17 is rotated for a certain number of times every minute after the start of washing. The number of pulses output from the Hall IC 40 in the case where it is made to run is measured, and the number of pulses output from the Hall IC 40 during a certain time at the start of dehydration is measured. The output from the Hall IC 40 under each condition is obtained. The number of pulses to be measured, the time from the start of water supply to the reset water level is measured, and the time and number of times under each condition are measured. The microcomputer 27 opens and closes the water supply valve 10 based on the above input signals and based on a control program. Opening and closing of the drain valve 13, driving and stopping of the washing motor 20, switching of the rotation direction,
The display units 28a and 28b are controlled. The display unit 2
At 8a, the course time, the washing time, the number of rinses, the dehydration time and the like are displayed on the operation panel 6. The microcomputer 27 has an operation process and measurement data of each sensor and the like.

The following specific operations are performed to reproduce and display the operation steps such as the time from power-on to power-off, washing time, number of rinses, dehydration time, and the like stored in the non-volatile storage means 41 and the measurement data. I do. As a method of operating the reproduction display of the operation process, for example, the power switch 33 is turned on by pressing the power switch 33 while pressing the switch 31 of the standard course of the key input unit 29 on the operation panel 6,
Press the start switch 32 five times. Hereinafter, this operation is referred to as “specific key A operation”. By the "specific key A operation", the reproduction of the operation process is started by a program pre-installed in the microcomputer. After the "specific key A operation", a specific key operation that can change the speed of the reproduction display is performed, whereby the operation process is reproduced and displayed on the display unit 28a at the changed speed. To change the speed, the switch 31 of the standard course is kept pressed for 3 seconds. Hereinafter, "Specific key B operation"
Called. By the "specific key B operation", the operation process can be reproduced and displayed at, for example, 10 times speed. The above "Specific key"
If there is no "B operation", the operation process is reproduced and displayed at a normal speed. Next, an operation method for reproducing and displaying the measurement data of each sensor will be described below. How to operate the reproduction display of the actual measurement data of the load sensor Press the power switch 33 to turn it on, and press the start switch 32 three times while pressing the switch 31 of the standard course. Press the switch 34 of the time-saving course in the operation state of the operation method of reproducing and displaying the measured data of the cloth circumference sensor. Then, the switch 35 of the course is pressed in the operation state of the operation method of reproducing and displaying the measured data of the dehydration start sensor. In the operation state of the operation method of reproducing and displaying the total number of rotations of the motor since the start of dehydration, the switch 36 of the squeeze switch is pressed. Then, the switch 37 of the blanket course is pressed in the operation state of the operation method for reproducing and displaying the number of rotations during dehydration. The switch 38 of the dry course is depressed in the operation state of the operation method for reproducing and displaying the measured data of the feedwater flow sensor. Press the switch 39 of the course of your own in the operation state of the operation method of reproducing and displaying the water supply time when the pump function is used. The switch 31 of the standard course is pressed in the operation state of the operation method of reproducing the total use time * the number of uses from the time of purchase. Data reproduced and displayed by the above operation method is displayed on an LED 28b provided on the operation panel 6. In addition,
In order to increase the display speed of the above-mentioned reproduction display, the display speed can be changed by pressing the "water level" key in each display state. By the above operations, the time from the power-on to the time of power failure and the time and number of each operation process of washing, rinsing, dehydration from the point of stopping during the operation, the measurement data of each sensor, etc. are reproduced and displayed. it can. In addition,
The operation method of the specific key operation is not limited to the above method, and another operation method is also possible. The content of the reproduction display can be changed depending on the capacity of the nonvolatile storage means 34 and the number of use. The display speed can also be specified by a program.

According to the first aspect of the present invention, the operation process and the measurement data of each sensor and the like stored in the non-volatile storage means are performed on the display unit by performing a specific operation method. It can be reproduced and displayed. Therefore, the market
Since it is possible to confirm the operation process of the product and to judge the content of the failure, it is possible to take measures against market claims.
