Abstract

PURPOSE:To utilize the output of a motor to the maximum by setting automatically the speed of revolution of the motor, the electric power supply time and the stop time being suitable for the load quantity of the washing, when the number of times in the case it does not rotate by the prescribed speed of revolution within a prescribed time reaches a prescribed number of times at the time of electric power supplying. CONSTITUTION:At the time of electric power supplying to a motor, in the case the prescribed motor longest operation time 60msec elapses before, reaching eight times of the prescribed speed of revolution, the electric power supplying to the motor 19 is stopped at this time point, and after the prescribed motor stop decision time 180msec elapses, the electric power supply is executed in the opposite direction to the motor 19. In such a state, when the case when the prescribed motor longest operation time 600msec elapses before reaching eight times of the prescribed speed of revolution reaches a fourth time, it is decided that the load is large, the speed of revolution of the motor is lowered, the motor longest operation time is shortened to 570msec, and the motor stop decision time is lengthened to 190msec.

Next, I will explain the operation, especially when performing strong washing.

First, the laundry and a certain amount of detergent are placed in a washing/dehydrating tank (4).
When the operation switch (14) is operated to start operation, the water supply valve (20) is first opened and water is poured into the water tank (
27) and the washing and dewatering tank (4), and when the water is supplied to a certain level according to the output from the water level sensor (23), the water supply is stopped and the motor (19) is turned on by the output from the control device (9). A motor control process begins in which the motor is energized and performs a forward/reverse operation with a period of time during which the energization is stopped.

When the motor (19) rotates, the speed generator (26) also rotates, and the speed generator generated voltage, which is a sine waveform output from its coil, is shaped into a 5-square wave by the motor rotation detection circuit (15). It is converted into voltage and the control device (

Therefore, in the case of powerful washing, the number of rotations of the motor (19) during one energization time is set to, for example, 8 rotations, which is higher than in the case of standard washing, and the speed generator (26) is connected to the control device (9 ) is the number of pulses output to the motor (19
) When 129 pieces for 8 rotations are detected, the control device (9)
Then, it is judged that the motor (19) has rotated 8 times (Stesobro), and the power to the motor (I9) is stopped (Stenobuni).

Even after the power supply to the motor (19) is stopped, the agitator (5) and the motor (19) continue to rotate due to inertia, and the speed generator (26) also generates pulses due to this inertia, as shown in FIG.

Provided that the power to the motor (19) has stopped (
The control device (9) starts counting these inertial pulses, but as shown in the waveform diagram in Fig. 9, after counting 16 pulses (steps H, H), the control device (9) calculates the stop judgment time up to that point. Clear the inertia pulse count, then stop judgment time 180m
It is determined whether 5ec has been reached (step E). This one
8 (hasec) is a stop time shorter than that during standard washing, and is set for strong washing.

Then, by stopping 180m5ec, the agitator (5

In this way, the motor (19) is energized for 8 rotations, and then the energization is stopped.After the energization is stopped, 16 inertial pulses are generated, and after a stopping time of 180 m5ec, the motor (19) is turned again in the opposite direction. Power is applied and this process is repeated to perform strong washing, but even if the energization time to the motor (19) reaches 600 m5ec before the motor (19) has completed 8 revolutions (step opening). (to step), the power supply to the motor (19) is stopped.

[Problem to be solved by the invention] In this way, in strong washing, the angle (time) of energizing the motor is increased (e.g. 8 rotations or 600M5ec),
Although the stop time is set short (for example, 180m5ec), these set values are set at 50 to 80% of the maximum capacity of the washing and dehydrating tank, taking into account the bath ratio in order to obtain a high degree of cleaning in relation to the motor output. It is set uniformly based on the assumption that the amount of laundry will be less than a certain amount.

このため、洗濯物の量を最大容量まで入れて強力洗いを
行うと、モーターに負担がかかり安全面で好ましくない
ばかりか、洗浄嗅も低下する。
For this reason, if you load the laundry to the maximum capacity and perform powerful washing, it will not only put a strain on the motor, which is not good from a safety perspective, but also reduce the cleaning smell.

また、電源電圧が低いと、洗濯物の量を最大容量の5〜
8割程度以下にしても所定の洗浄度が得られないことも

Also, if the power supply voltage is low, the amount of laundry can be reduced to 5 or more than the maximum capacity.
Even if the cleaning level is set to about 80% or less, a predetermined degree of cleaning may not be obtained.

On the other hand, if the amount of laundry is extremely small, even though it has the ability to powerfully wash a larger amount of laundry, this ability will not be used effectively and the motor will not operate efficiently. This is not a good thing.

The purpose of the present invention is to eliminate the disadvantages of the conventional example, and to take into account the quality and quantity of laundry, the level of power supply voltage, etc. when performing strong washing, and to adjust the power supply time to the motor in accordance with the above. and can rotate the agitator with stop time,
An object of the present invention is to provide an operation control method for an agitating washing machine that can utilize motor output to the maximum extent possible.

When the motor (19) is energized in the opposite direction, it rotates by the specified number of revolutions within the specified time when the motor (19) was previously energized, so this first mode is the one that passes through the load amount of laundry. Judging from this, it was done in the same mode as Nenoj's mode, and this was not repeated.

However, when the motor is energized, the maximum operating time (600ms) of the specified motor does not reach the specified number of rotations (8 times).
If ec) has elapsed and 7 has elapsed (step wo, wa, force), the power to the motor (19) is stopped at this point (steel control), and the specified motor stop judgment time (180 msec) is carried out in the same way as above. After the elapse of time, the dryer (19) is energized in the opposite direction.

And, before reaching the specified number of revolutions (8 times), the maximum operating time of the motor (600+++5ec) is reached.
When it reaches the 4th time (step force), it is determined that the load is large and the motor is set to the second mode as shown in Figures 2 and 3. Lower the rotation speed to 7.5 times and increase the motor maximum operating time to 57
Shorten the motor stop judgment time to 19 seconds.
Increase the length to 0m5ec and count the number of overload detection by 1 (Stepta).

In this way, if the specified maximum motor operation time elapses before the motor rotation speed reaches the specified rotation speed, you can change the mode one by one to ensure that the motor runs in the mode that is appropriate for the amount of laundry loaded. control so that Then, this mode change operation is repeated several times (in this embodiment, seven modes are set, so it is repeated six times), and when the sixth time is reached, the energization of the motor (9) is stopped and the process ends. do.
