Field of the Invention The present invention relates to washing and rinsing when water level is set manually regardless of the amount of clothing or when wet level is set and water level is automatically set higher. The present invention relates to a method for controlling a washing machine in which the balance agitation is performed at an optimum water level.

が多くなり、信頼性の面で問題が生じる。In the above prior art, particularly when the water level is determined by manual setting, for example, when washing is performed with a high water level set with a small amount of clothing, the water level is lowered by one step after washing and stirring. Even if the water is drained to the water level (medium water level) and the balance is agitated, the amount of water for the small amount of clothing is quite large, and the clothing looks like floating in the water. ) In many cases. As a result, the swing of the washing and dewatering tub at the start of dehydration becomes large, so that the number of times of dehydration stop by the safety switch ON increases, and a problem occurs in reliability.

秒間バランス撹拌を行うように制御する。In order to achieve the above object, a water level (water level A) automatically set by detecting a cloth amount performed before water is supplied into a washing tub, or a water level manually set by a water level switch in advance. The water level determined by the setting (water level B) is then supplied to the specified water level, and then the amount of cloth is detected again to compare the determined water level (water level C). When the water level is lower than the water level B, the washing is performed at the water level A or the water level B, and after rinsing and stirring, the water is drained to the water level C and then the balance stirring is performed for several seconds or tens of seconds.

ンス状態を少なくすることができる。Regardless of the amount of clothing, when the water level is manually set to a high level by the water level changeover switch, or when a small amount of wet clothing is inserted, the water level is increased by detecting the amount of cloth without water. Even if it is set automatically, the balance agitation after washing and rinsing agitation is performed at the optimum water level determined by detecting the amount of cloth at the specified water level. Can be less unbalanced.

し、最適水位(水位A)を自動設定する。The operation of the washing machine in the above configuration will be described. When the user puts on clothes, presses the power switch button 29 to turn on the power switch, and presses the start button 33, a fully automatic operation is performed. First, before the water is supplied into the washing and dewatering tub 5, the cloth amount is detected. this is,
0.5 seconds ON-1.0 seconds OFF reverse agitation is performed, and the back electromotive force of the motor 8 when the rotating body 6 rotates by inertia at the time of stop is determined by the terminal voltage of the motor 8 and the driving capacitor 8a. This is detected, converted into a DC short-wave pulse, and the time t 1 between the pulses is measured to determine the amount of cloth. That is, when the clothes is large, the resistance to the rotating body 6 is large, the time t 1 between hindered pulses coasting becomes longer, the time t 1 between pulse opposite in the case where the amount of the clothes is small
Becomes shorter. The measurement of the time between the pulses is performed by using the first pulse (a) of the double-wave detection pulse detected by the circuit shown in FIG.
The width t 1 of the rise time of the first pulse (b) was measured (FIG. 5), and a time obtained by multiplying the total time of two times in the counterclockwise direction by repeating this three times was stored in the microcomputer in advance. By comparing the relationship between the amount of clothing and time, the amount of clothing is determined, and the optimum water level (water level A) is automatically set.

The reverse stirring (balanced water flow) of ON-0.6 seconds OFF is performed for several seconds or tens of seconds, and the unbalanced clothes entangled by the washing and stirring are loosened and equalized. After the balance is agitated, a signal from the controller
The drainage device 15 is energized to start draining, and the water level sensor 13 detects whether or not the water has been drained to a specified water level. After the drainage, the solenoid 11 is also energized to start the dewatering operation. After the completion of the dehydration operation, water is supplied to the optimum water level, rinse and stirring are performed, and drainage and dehydration steps are performed in the same manner. The above operation explanation is for the case where the water level according to the amount of clothing is automatically set, so that the balance stirring is performed at the optimum water level according to the amount of clothing, so that the clothes entangled by washing and stirring can be loosened. Has the effect of equalizing.

高くなる)。However, when a small amount of clothing is wet, there is a high possibility that the determination of the clothing amount without water is automatically set to a higher water level than the clothing amount. In addition, when a small amount of clothing is thrown in and the water level is set to, for example, a high water level by the water level change switch of the external operation switch 30, the balance agitation is performed after washing and stirring at the high water level. Therefore, since the amount of water is considerably large and clothes float in the water, the clothes are often uneven (unbalanced) after the end of the balance even if the balance is stirred. As a result, when the spin-drying is started, the swing of the washing and spin-drying tub 5 increases, so that the safety switch 50 is turned on and the spin-drying process is stopped (the operation rate of the safety switch 50 increases).

制御する。The balance stirring control in the case of manual setting will now be described with reference to the flowchart of FIG. 6. Clothes are turned on, and the water level (water level B) is manually set by the water level switch of the external operation switch 30 (step 51). When the washing is started by pressing the start button 33 (step 52), first, water is supplied to a minimum water level (regulated water level) (step 53), and cloth amount detection and agitation are performed. ) Is determined (step 54), and the microcomputer compares the manually set water level (water level B) with the optimum water level (water level C) (step 55). If the optimum water level (water level C) is determined to be lower than the manually set water level (water level B), water is supplied to the manually set water level (water level B) (step 56).
Then, washing and stirring are performed (step 57). After the washing and stirring or washing and balance stirring, the balance is stirred for several seconds or tens of seconds, and then for 0.3 seconds ON-0.6 seconds OFF after draining to the optimum water level (water level C) (step 58). , 0.6 seconds ON-0.6 seconds OFF and 0.3 seconds O
Balance agitation by combination of two different time periods of N-0.6 seconds OFF, and 0.6 seconds ON-0.6 seconds OF
F, 0.3 second ON-0.6 second OFF, 0.2 second ON-0.6
After performing balance agitation (step 59) by a combination of three different time limits of seconds OFF, control is performed so as to perform drainage and dehydration. Alternatively, as shown in the flowchart of FIG. 7, after the washing and stirring or the washing and the balance stirring are completed (step 57), the balance stirring is performed during drainage to the optimum water level (water level C) (step 58), and then the optimum water level Even at (water level C), after performing the balance stirring for several seconds or several tens of seconds (step 59), control is performed so that drainage and dehydration are performed.

By performing a comparison, when the optimum water level (water level C) is lower than the optimum water level (water level A), step 57 in FIGS.
The following control is performed. By this control, the effect of reducing the unbalanced state of the clothes by the balance agitation is improved, so that the safety switch 50 is turned ON at the time of starting dehydration and the dehydration process is less likely to be stopped. Further, since this control is performed only when the operations of agitation (washing, rinsing), drainage, and dehydration continue, if only the washing is set by the external operation switch 30, the drainage after the washing and stirring is completed. The balance stirring is performed in the state of the manually set water level without stopping, and the apparatus is stopped in that state after the end, so that the user can use the washing liquid twice.
