The digital display 21 specifically displays the current time, the reserved time such as the start of operation, the start and stop times of the silent course, and the like. Further, a detected value of the rotation speed of the motor 12 or the ambient temperature is input to the control unit 3. 43 is a power supply. The above-mentioned content is a configuration known as an electric washing machine, and does not require any further description. The display panel 4 is provided with a display unit 44 that indicates an integrated value of the operation time. The display unit 44 includes an integrated display unit 45 that indicates an integrated value from the start of use of the washing machine and an integrated display unit 46 that indicates an integrated value determined by the operation mode or the date.
Consists of The setting is made by the setting button 47. FIG. 3 shows details of the control unit 3 shown in FIG. In the figure, a central processing unit (CPU) 51 is connected to a timer 53, a memory 52, an input device 54, and an output device 55, and inputs and outputs signals, respectively. Specifically, C
The PU 51 performs arithmetic and logical operations, controls reading and writing of the contents of the memory designated address, controls input / output to the designated addresses for the input / output devices 54 and 55, and controls the flow of the program. The memory 52 stores programs and data, and is a RAM having both reading and writing functions.
And a ROM having only a read function. The input device 54 and the output device 55
1 is a circuit that exchanges data with the I / O.
It is called O port. As generally known, the input device 54 includes a power switch 63, a cloth amount sensor 61, a cloth sensor 68, a water level sensor 64, a lid switch 65, a program selection switch 66, a start / stop switch 67, and a temperature sensor 62. Are connected. The output device 55 is connected to a washing motor 71, a water supply valve 72, a hot water supply valve 73, a drain valve 74, a clutch solenoid 75, a reporting device 76, and the like.
Based on a command from U51, a series of operations from washing to dehydration are performed via the input / output devices 54 and 55. The matters described above are well-known matters and need not be further described. The power switch 63 (43 in FIG. 1) is pressed, an arbitrary washing course is selected by the program selection switch 66, and water supply is started by the start / stop switch 67. The washing water level from the start of water supply to the stop of water supply is detected in steps, and in each of the steps, the temperature of the washing water is controlled in a predetermined temperature direction, and if water is supplied to the washing tub to a certain level, The agitator is operated for a few seconds to move the garment, and the resistance change of the agitator based on the size of the garment is compared with the value stored in advance in the microcomputer to detect the amount of the garment, and then the amount of the garment is detected. Automatically sets the final washing water level according to. When the water level sensor 64 notifies the microcomputer that the final washing water level has been reached, the agitator 17 is again operated for several rooms to move the laundry, and the resistance value of the agitator 17 at this time changes. The microcomputer compares the value of the clothing with the value stored in the microcomputer in advance to detect the quality of the clothing, corrects the initially set washing time, and starts washing. That is, the initially set washing time is corrected to the optimum washing time in real time based on the detection data that comprehensively considers the amount of washing water, the amount of washing, and the quality of washing, and washing is started. After the washing is performed for a certain period of time, the drain valve 13 is opened, and the washing water in the water receiving tub 10 is drained out of the machine via the drain hose 15. When the water level sensor 64 detects that the washing water in the water receiver 10 has been completely drained, the process proceeds to intermediate dehydration, and the washing and dewatering tub 18 is rotated at a high speed to wash the laundry containing the detergent in the clothes. Centrifuge the water. After the dehydration, water is supplied for rinsing, and the rinsing is started after reaching a specified water level. Intermediate dehydration and final dehydration are performed in the same manner as in the above-mentioned intermediate dehydration, and rinsing is performed in the same manner as in the above-mentioned rinsing. The operation is set by the display panel 4. The set washing conditions are displayed on the LED display 21 as described above. The LED display 21 displays a washing course, a washing water level, a washing time and a water temperature, a number of rinses, a dehydration time, a current time, and the like. The washing time is accumulated by the CPU 51. The accumulated washing time is stored in the memory 52. The following driving times are accumulated and stored based on the washing information.・ Operation time obtained by accumulating the washing time set based on the detection data such as the washing water level, cloth amount, cloth quality, and washing water temperature ・ Operation time obtained by adding the washing time set by the timer ・ Washing time in the preset operation mode The operating time obtained by integrating the washing time during the limited period of time. The CPU 32 has a function of multiplying the integrated operating time by the charge per unit time to calculate the charge. This can be convenient depending on the purpose of use. Therefore, in this case, the charge may be displayed on the display panel 6 together with the accumulated operation time. The charge display may be performed on a separate PC.

As described above, according to the present invention, the operating time of the washing machine is accumulated based on the washing information and displayed on the display panel, so that the operating time can be accurately grasped. became. As a result, rather than "how many years have been used" as in the past, instead of "how many hours have been used", the actual usage time is accurately grasped against the design durability time, such as
Judgment of replacement time or regular maintenance time has become easier. In addition, since the operation time for each operation mode or for each month and day is ascertained, the operation rate in business can be ascertained, and, for example, the usage charge can be ascertained more accurately.
