Description of the Related Art Conventionally, balance agitation control is performed by directly performing balance agitation at the water level at which washing and agitation is performed, or by performing washing and agitation irrespective of whether the water level is manually set or automatically set by detecting a cloth amount. In some cases, the water is drained to a level lower than the water level, and then the balance is stirred.

の回数が多くなり、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 stirred, the amount of water for the small amount of clothing is quite large, and the clothing is floating in the water. (Balanced state) 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 stopping dehydration by turning on the safety switch increases, which causes a problem in reliability.

Accordingly, it is to reduce the operation rate of the safety switch at the time of starting dehydration.

位の状態でバランス撹拌を行うようにする。In order to achieve the above object, the present invention provides a motor for driving a washing and dewatering tub or a stirring blade, and a rotating body for washing provided with control means for controlling the power supply to the motor. The amount of clothing is determined by the resistance of the clothing to be added, and in the one that determines the optimal water level,
After the water level is manually set in advance with the water level select switch (manual setting water level), when the operation is started by pressing the start button, if the optimum water level based on the cloth amount judgment is lower than the manually set water level, after washing and rinsing and stirring, the optimum water level Control to balance and stir after draining
When only washing is set, after the washing and stirring are completed, balance stirring is performed at the manually set water level.

バランス状態を少なくすることができる。[Function] Regardless of the amount of clothes, even when the water level is manually set and the laundry is washed, the balance agitation after the end of the washing and agitation is performed at the optimum water level determined by the detection of the amount of the clothes, so the balance agitation effect is lost. Without this, it is possible to reduce the unbalanced state of the clothing before the dehydration operation.

When 3 is detected, power supply to the water supply electromagnetic valve 24 and the solenoid 11 is stopped, and power is supplied to the motor 8 to perform stirring. At this time, since the clutch device 10 is in the dehydrated state, the clutch device 10 is surely put into the washing state. In addition, since the cloth is not damaged, the reverse stirring water flow is stronger than the cloth amount detection stirring and weaker than the normal stirring for 0.5 seconds. After operating for 0.5 seconds with 0.5 second off, cloth amount detection and stirring is performed.

拌を実行する。In the cloth amount detection process, the reversal agitation of 0.4 second on-1 second off is performed, and the back electromotive force of the motor 8 when the rotating body 6 rotates by inertia when the cloth is off is used for the motor 8 and the driving capacitor. detected by 8a of the terminal voltage, which is converted into a DC square wave pulse, it is to determine the laundry weight by measuring the time t 1 between the pulses. That is, since if the laundry is large large resistance to the rotating body 6, the time t 1 between hindered pulses coasting becomes longer, the time between pulses opposite in the case where the amount of laundry is small t 1 Becomes shorter. The measurement of the time between the pulses is one of the two-wave detection pulses detected by the circuit shown in FIG.
The rise time width t 1 of the first pulse (a) and the third pulse (b) is measured (FIG. 5), and this is repeated 20 times, and the total time is stored in the microcomputer beforehand. Compared with the relationship, the amount of cloth is determined, the water level according to the amount of washing is automatically set, and washing and stirring are performed after water supply to the automatically set optimum water level.

Reverse inversion (balance water flow) for seconds on-0.6 seconds off is performed for several seconds or tens of seconds, and the unbalanced clothes entangled by washing and stirring are loosened and made uniform. After the balance is agitated, a signal from the controller
The drain device 15 is energized to start draining, and the water level sensor 13 detects whether or not the water has drained to a specified water level,
After the drainage, the solenoid 11 is also energized to start the dehydration operation. After dehydration operation, supply water to the optimum water level,
Rinsing and stirring are performed, and drainage and dehydration steps are performed similarly. The above description of the operation is for the case where the amount of clothing is determined by sensing of the clothing amount sensor 37 and the water level is automatically set according to the amount of clothing. Is performed, there is an effect of loosening the clothes entangled by the washing and stirring and equalizing them. However, 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 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 becomes large, so that the safety switch 50 is turned on and the spin-drying process is stopped (the safety switch 5).

オンし、脱水行程が停止してしまうことが少なくなる。The balance agitation control in the case of manual setting will now be described with reference to the flowchart of FIG. 6. After putting on clothes, the water level is manually set by the water level switch of the external operation switch 30 (step 51), and the start button 33 is started. When the washing is started by pressing (step 52),
First, water is supplied to the minimum water level (step 53), the amount of cloth is detected and agitated, the optimum water level according to the amount of clothing is determined (step 54), and the microcomputer compares the manually set water level with the optimum water level. (Step 55). Here, when it is determined that the optimum water level is lower than the manually set water level, water is supplied to the manually set water level (step 56), and washing and stirring are performed (step 57). After the washing and stirring are completed, the water is once drained to the optimum water level (step 58), and then for several seconds or several tens of seconds, the balance is stirred for 0.3 seconds on and 0.6 seconds off, or
Balance agitation by a combination of two different time periods of 0.6 seconds on-0.6 seconds off and 0.3 seconds on-0.6 seconds off,
Furthermore, 0.6 seconds on-0.6 seconds off, 0.3 seconds on-0.3.
After performing balance agitation (step 59) by a combination of three different time periods of 6 seconds off, 0.2 seconds on and 0.6 seconds off, control is performed to perform drainage and dewatering. By this control, the effect of reducing the unbalanced state of the clothes by the balance stirring 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.

Therefore, it corresponds to a user who intends to use the washing liquid twice.
