機を提供するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric washing machine that supplies water to an optimum water level depending on the amount of clothes in the automatic washing machine. In this type of electric washing machine, as shown in FIG. a cloth amount detection device 4 for detecting the magnitude of the load applied to the drive device 3 relative to the amount of cloth and determining the amount of cloth; a water level detection device 6 for detecting the water level in the washing tub 1; The required water level for the amount of cloth is determined by comparing the detection result output of the water supply device 6, the detection result output of the cloth amount detection device 4, and the water level data output from the water level detection device 6, and the water supply device 6
The water level determination device 7 is equipped with a water level determination device 7 that outputs a signal to the water level. The water level detection device 6 consists of a pressure sensor that measures the pressure generated by the water level and uses it as the water level. The water level determination device 7 outputs an output to the water supply device 6 until the water level reaches a predetermined water level for detecting the amount of cloth;
When a predetermined water level is reached by water supply, the cloth amount detection device 4 outputs an output to the drive device 3 to start stirring. The magnitude of the load on the drive device 3 is detected as an input signal by the cloth amount detection device 4, and the amount of cloth is determined. The water level determination device 7 determines the optimum water level according to the amount of cloth, and washing is carried out using an appropriate amount of water without damaging the laundry. However, with this configuration, if you put the laundry in after the detergent has been sufficiently dissolved in the water in the washing tub, it will take about 1 to 2 minutes of stirring for the detergent to dissolve in the water, and the laundry will be loaded after the detergent is dissolved. By the time detergent is added, the amount of cloth has already been determined at the beginning of stirring, so stirring continues with less water, causing problems such as damage to the cloth and stains not being removed. When washing laundry with items in it, turn off the power switch once the detergent has dissolved, then turn the power switch back on.
A method of loading the laundry, starting the operation, and determining the amount of cloth is required, which has the problem of poor operability and ease of use.Objective of the Invention The present invention focuses on these conventional problems, and Even if you first dissolve the detergent in the water in the washing tub and then put the laundry in, it will automatically determine the amount of laundry without requiring the operator to turn the power off or turn it off, allowing you to wash the laundry at the optimal water level depending on the amount of laundry. This is to provide a washing machine that can

The water level determining device is provided with a water level determining device that determines a required water level and outputs an output signal to the water supply device, and the water level determining device outputs an output signal to the water supply device until a preset minimum water level for detecting the amount of cloth is reached. At the water level, the output is sent to the cloth amount detection device, and the amount of cloth is determined using a strong water flow. When the water level determined by the water level determining device is higher than the minimum water level, water is supplied up to the determined water level, and after the water supply is completed, washing is performed with a strong water stream.

The magnitude of the load caused by stirring is motor 1o.
The current transformer 11 detects the magnitude of the current flowing through the current transformer 11. The electrical signal from the current transformer 11 is A
/D Converted to digital data by converter 12, input terminal B
is input to the microcomputer 13 from which the amount of cloth is determined (step 3 in FIG. 3). The water level determination device 7 determines the optimum water level according to the amount of cloth (step 4 in FIG. 3). Next, it is determined whether the water level determined by the water level determining device 7 is a small water level or a water level greater than a small amount, that is, a low water level, a medium water level, or a high water level (step 6 in FIG. 3). If the water level is determined to be above the low water level, this means that there is some kind of laundry in the washing tub, and detergent is usually added to wash the tub. However, when washing the laundry by dissolving the detergent sufficiently in the water in the washing tub,
During the determination of the amount of cloth, water and washing are in progress, and the water level determined by the water level determination device 7 is always determined to be a small amount water level. In other words,
When it is determined that the water level is low, there is only water in the washing tub, water and detergent, or only a small amount of laundry (for example, 20
02 or less), this is the state in which ants exist. In this case, stir for 2 minutes to sufficiently dissolve the detergent, such as powdered soap that is difficult to dissolve in water (Step 6 in Figure 3).
). Next, after stirring for 2 minutes, repeat step 3 in Figure 3.
, 4, the amount of cloth is determined and the water level is determined (step 7.8 in FIG. 3).

Further, by using a weak water flow during the stirring step, damage to the cloth can be reduced even if laundry is thrown in during the stirring step. Additionally, in the next washing step, the water flow can be automatically made stronger to increase the cleaning power.
