The present invention solves the above problems by displaying the washing time, number of rinses, and spin-drying time after clearly determining them by a cloth amount detection means, and displaying them during the process during which the cloth amount detection is being performed. The purpose is to provide a display section for clarity and display information that is easy for the user to understand.

Means for Solving the Problems In order to achieve the above object, the present invention comprises a cloth amount detection means for detecting the amount of cloth, and a control means for controlling the operation of the washing machine based on the detection data of the cloth amount detection means. , a display unit that displays the water level, washing time, number of rinses, spin-drying time, etc., and the control means displays the current water level on the display unit that displays the amount of cloth being detected until the amount of cloth is detected. and the washing time, number of rinses, and spin-drying time are not displayed, and the display after detecting the amount of cloth displays the water level, washing time, number of rinses, and spin-drying time determined by the cloth amount detection means, and the washing time, number of rinses, and spin-drying time are not displayed. The structure is such that the display is turned off while the amount of cloth is being detected.

Function: With this configuration, the display indicating that the entire cloth is being detected operates the display section that indicates that the amount of cloth is being detected, and the display after the amount of cloth has been detected turns off the display that indicates that the amount of cloth is being detected. By displaying the determined water level, washing time, number of rinses, and dehydration time, accurate and easy-to-understand information can be provided to the user.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 is a block diagram showing a washing machine control device in an embodiment of the present invention. In the figure, 1 is the switch for selecting and setting the washing course, and the input switch for changing the water level, washing time, number of rinses, and spin-drying time, 2 is the lid switch, 3 is the water level sensor that detects the water level, 4 is the water level, washing time.

A display section that displays the number of rinses, dehydration time, and process progress; 6 is a motor that rotates the pulsator and dehydration tank; 6 is a water supply solenoid valve; 7 is a drain solenoid valve; 8 is a motor 5. Water supply solenoid valve6. This is a drive circuit section that drives the drain electromagnetic valve 7, and is composed of a bidirectional thyristor, a transistor, and the like. 9 is an input section and an output section.

The amount of cloth is determined by stirring for a certain period of time and detecting the variation in motor current at that time. 11 is a commercial power supply. 12 is a DC power supply that supplies each block.

The operation of the present invention will be explained with reference to FIGS. 2 and 3.

FIGS. 2 and 3 show an operating section, which is composed of a display section 4 and an input switch section 1. As shown in FIG. 11-1
9 is a switch, 11 is a water level setting, 12 is a washing time setting, 13 is a rinsing number setting, and 14 is a dehydration time setting.

16 to 18 are course switches, and time limits and sequences corresponding to the courses are stored in advance. 16 is the large course setting, 16 is the wool course setting, 17 is the saving course setting, and 1B is the sensor course setting.The water level, washing time, number of rinses, and dehydration time are automatically set according to the amount of cloth using the cloth amount detection means. be done. 19 starts driving,
- Start with a stop at - time, the low water level indicator lights up and the indicator 20 that is detecting the amount of cloth flashes, indicating that it is the step of detecting the amount of cloth, and the water supply process is started. At this time,
Still time to wash.

Since the number of rinses and spin-drying time have not been determined, the washing, rinsing, and spin-drying indicators are not displayed (lights are turned off). Next, when the water level reaches a small amount, the water supply is stopped, stirring is performed, and the amount of laundry in the tub is determined by the amount of laundry detecting means. Once the amount of laundry is determined, the water level, washing time, number of rinses, and spin-drying time are determined by the operation control unit 9 according to the determined values. The determination value and sequence are stored in advance in the storage section of the operation control section 9. For example, if the amount of cloth is large and the water level is determined to be high, the washing time will be 12 minutes, the number of rinses will be 2 times, and the spin drying time will be 5 minutes, and if the water level is determined to be medium,
9 minutes, 2 times, and 6 minutes, respectively. When it is determined that the water level is low, it is 6 minutes, 2 times, and 3 minutes, respectively. When it is determined that the water level is small, it is 3 minutes each.

Set twice for 1 minute.

When the amount of cloth is detected and the water level, washing time, number of rinses, and dehydration time are determined, the display section 4 displays the determined water level and washing time, as shown in FIG.

The indicators corresponding to the number of rinses and dehydration time are lit, and the indicator 2o that is detecting the amount of cloth is turned off. Figure 3 shows the display when it is determined that the water level is high. Water is then supplied again to the high water level, after which the washing process begins and operation continues according to the sequential sequence.

Effects of the Invention As is clear from the above-described embodiments, according to the present invention, the display up to the detection of the amount of cloth operates a part of the display indicating that the amount of cloth is being detected, and the washing and rinsing operations are performed.

The spin-drying indicator is turned off, and the display after detecting the amount of cloth turns on the washing, rinsing, and spin-drying indicators determined by the amount of cloth detection means, and turns off the display for detecting the amount of cloth, so it is accurate and easy to understand. It is possible to display the progress of washing, which improves usability.
