Abstract

PURPOSE:To execute a correct display by operating a cloth quantity detecting means with a start, deciding a washing time, a rinsing frequency and a dewatering time, preventing the display of a remaining necessary time until the remaining necessary time is operated and made clear, and executing the display after it is made clear. CONSTITUTION:When a start switch is pushed, an action control part 8 starts an operation, and a figure display 3 does not display the remaining necessary time since it is not decided. A feed water is executed up to a small quantity water level by a feed electromagnetic valve 5, a motor 4 is driven, a laundry is agitated, the fluctuation degree of a motor current at such a time is detected, the cloth quantity is decided, and the water level, washing time, rinsing frequency and dewatering time are set by the action control part 8. The remaining necessary time is operated, and the remaining necessary time is displayed on the figure display 3. Next, the feed water is executed up to a set water level, and a washing operation is started. In such a way, a user can correctly know the necessary time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a washing machine control device equipped with a cloth amount detection means and a remaining time display.

Conventional Technology Conventionally, when this type of washing machine is turned on and the start switch is operated, the predetermined remaining time is displayed on the numerical display, and then the water level is displayed using the cloth amount detection means. The washing time, number of rinses, and dehydration time are determined, and the display changes to the remaining time calculated based on the determined time and number of rinses.

Problems to be Solved by the Invention However, in such a configuration, the remaining required time determined by the cloth amount detection means may differ from the predetermined remaining required time. Further, since the cloth amount detection means operates at the beginning of operation and the remaining time required is changed, there is a problem in that the user may misunderstand the time required for washing.

The present invention is intended to solve the above-mentioned problems, and aims to correctly inform the user of the remaining time required only after the remaining required time is clearly determined by the cloth amount detection means.

Means for Solving the Problems In order to achieve the above object, the present invention hides the display of the remaining time from the start to the detection of the amount of cloth in the numerical display that displays the remaining time required for operation. The subsequent display is configured to display the remaining required time determined and calculated by the cloth amount detection means.

Effect: With this configuration, by displaying the remaining required time after the remaining required time becomes clear, the user can accurately know the required time.

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 a switch section for selecting and setting a washing course, 2 is a switch section for selecting and setting a washing course, and 2 is a switch section for selecting and setting a washing course.
Display section that displays washing time, number of rinses, and dehydration time, 3
is a numerical display that displays the remaining time nJff, and 4 is for pulsator and dehydration! (not shown), 6 is a water supply solenoid valve, 6 is a drain solenoid valve, 7 is a drive circuit unit that drives the motor 4, water supply solenoid valve 5, and drain solenoid valve 6, and includes semiconductor switches, transistors, etc. It is configured. Reference numeral 8 denotes an operation control section which includes an input section, an output section, an arithmetic section, a storage section, etc., and performs predetermined sequence control, and is implemented by a microcomputer, for example. Reference numeral 9 denotes cloth amount detection means, which determines the amount of cloth by, for example, supplying water to a small amount of water level, stirring it, and detecting the variation in motor current at that time. 10 is a commercial power supply. 11 is a DC power supply that supplies each block.

The operation of the present invention will be explained with reference to FIG.

Press the start switch to start operation (Step 1)
2) The number display 3 displays "-1" because the remaining time has not yet been determined (step 13). When the water is supplied to a small level (step 14.15), the water supply is stopped and the motor 4 is driven to agitate the laundry. At this time, the variation in motor current is detected and cloth IT judgment is made. For example, the cloth amount detection means 9 and the operation control unit 8 determine that the amount of cloth is small when the fluctuation of the motor current is small, and that the amount of cloth is large when the fluctuation of the motor current is large (step 16.17). .

When the amount of cloth is large, the process branches to step 1, when the amount of cloth is medium, the process branches to step 19, and when the amount of cloth is small, the process branches to step 2°.

At this time, the operation control unit 8 controls the water level, washing time, number of rinses,
The dehydration time is set, the remaining required time is calculated, and the remaining required time is displayed on the numerical display 3 (step 21). Next, water is supplied to the set water level (step 22), and when the water supply is completed (step 23), the washing operation is started (step 24).

FIG. 3 is a display example of the numeric display 3 from step 12 to step 2o in FIG. FIG. 4 shows an example of the display on the numeric display 3 from step 21 to step 24 in FIG.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the cloth amount detection means operates from the start, determines the washing time, the number of rinses, and the spin-drying time, and calculates the remaining required time until it becomes clear. By not displaying the remaining time, but displaying the remaining time after the remaining time is clear,
The user can accurately know the required time.

Moreover, since the remaining time display does not change before and after the operation of the cloth amount detection means, it is possible to prevent the display from being mistaken as an erroneous display.
