In addition, 'sometimes when there are rope-like items on the washed plume or mixed with long strips, it may be new and clean, and the laundry will be complicatedly intertwined' and cannot be mistaken by the control operation. Lifted. At this time, there is no other way than the urging of the user to unwind the smear of the smear. Therefore, there is a problem that dehydration is stopped in a state where the imbalance of the laundry is not solved. The purpose of the & month is to provide a drum type washing machine that is controlled so that the dehydration operation performed after each step of washing and washing can be carried out smoothly, and the countermeasure operation can be performed when the unbalance of the washing: Means for Solving the Problem> For the purpose of describing the present invention, the drum type washing machine of the present invention includes: a tumble rolling system in which a rotating towel mandrel is located in a direction slightly inclined to a horizontal direction or a horizontal direction 10 15 20; The water tank is elastically supported in the frame of the washing machine, and is provided with a right 诰, +, # ^ returning roller, and a drum driving motor for driving the rotary drum driving motor and the control device. Used to control the foregoing operation, so that the front cools a, and the control device is activated in the first cylinder on the dewatered inner wall in each step until the laundry is easily attached to the washing reading speed of the washing machine. When the judgment value is used, the cloth balance determination based on the first inner wall on the inner wall is determined, and when the balance is good, the cloth balance determination is repeated, and it is not determined that the number of times reaches the pre-arrangement and the balance is judged. When the operation is repeated and the larger change determination T is repeated, the initial determination value is changed to the allowable range, and based on the operation of repeating the cloth balance determination described above, if the balance is good, the value of 1 or the change determination value is determined as described above. According to the foregoing configuration, the two rotating drums are rotated at a spin-drying speed. In the good case, the repeating is predetermined to be determined by the balance of the cloth, and it is not determined that the starting operation of the two-in-one dewatering operation in the balanced rotating drum is performed. The state of the y object is easily changed. Even if the washing materials are entangled with each other 7 1277677, the washing can be easily released by the repetition. The laundry is more complicatedly entangled with each other, and cannot be judged as balanced at the initial determination value. In the case of a good state, the initial determination value is changed to the change determination value of the allowable range width, and even if there is a slight imbalance, the dehydration operation is started, so that the dehydration 5 is not easily stopped halfway. In the above configuration, the control device is based on the foregoing. Controlling when the number of repetitions of the change determination value is a predetermined number of times, and performing an abnormality report by using the abnormality reporting device, that is, If there is a control operation, the entanglement of the laundry cannot be solved, and the user can be abnormally reported to urge the user to perform the process of releasing the entanglement. Further, when the control device determines that the cloth balance is good according to the change determination value, Controlling the dehydration (four) speed and performing the dehydration operation at the second dehydration rotation speed, and the second dehydration rotation speed is smaller than the predetermined dehydration rotation speed I5 rotation speed of the cloth when the cloth balance is good according to the initial determination value. It will not stop the X operation due to the control operation in the unbalanced unresolved condition. Even if there is a point imbalance, the dehydration operation will be performed. Since the dehydration rotation speed at this time is decreased to the second dehydration speed, the dehydration capacity is lowered. The dehydration time of the cow is controlled to be prolonged, and the dehydration condition is substantially equal to the dehydration rotation speed. Further (the control device controls when the first predetermined rotation speed is reached, so that the rotation driving direction of the rotary drum changes every time it is repeated, Because the direction of action applied to the washings is different, the state in which the washings are entangled with each other is easily released. EFFECTS OF THE INVENTION 8 1277677 According to the present invention, h 4 > * is subjected to a dehydration operation after each step of washing and washing, and the distribution state of the laundry in the rotary drum is regarded as a cloth balance for determination, :, I In order to balance well, the predetermined number of times of entering the dehydration operation will be repeated. • The start-up will make the state of the laundry in the rotating drum easy to change, and even if the washing is in a state of being entangled, it is easy to solve by repeating the operation. . tWhen the strips are entangled with each other, the cloth balance cannot be reached at the initial judgment value. When the balance is good, the initial judgment value is changed to the change range of the tolerance range. The judgment value is even if the balance is unbalanced. Operation, so dehydration is not easy to stop halfway. The dehydration operation performed at this time is controlled so that the dehydration suspecting speed is the second dehydration rotation L which is smaller than the predetermined dehydration rotation speed, and the dehydration operation can be performed even if there is a little imbalance. In addition, by controlling the abnormality reporting device to perform an abnormality report, even if there is a tangling of the washed object that cannot be released by the control operation, the user can be notified of the abnormality, and the user is urged to perform the process of releasing the winding.

The DC power generated is because the load state of the drum drive motor 5 is roughly proportional to the input current, so what is the negative; the fault detection circuit 26 can be connected in series with the circuit that supplies the converter 23 DC power. The voltage across the resistor 25 detects the input current 15 flow value, and the cloth amount detecting device 27 detects the amount of the laundry loaded into the rotary drum 1 based on the current value, as detected by the cloth amount detecting device 27. The amount of the object is used for the control operation described later, so that the amount of the laundry is stored in the memory provided in the control device 16. Next, the control device 16 outputs the control of the load driving device 2 to turn on the water supply. In response to the command, the water supply valve 12 is opened and the tap water is supplied from the water supply pipe connected to the water supply unit 15. The tap water is supplied to the water tank 3 while being mixed with the detergent charged in the water supply unit 15. The water supply amount in the water tank 3 is in accordance with The water supply time is set. When the water reaches the predetermined water, the amount of the laundry detected by the cloth detecting device 27, the water supply amount in the tank 3 is detected by the water level detecting device 19, 12 ^ 277 677 5 10 15 20 p, and the position detecting device 19 controls Sakiji 16 loses the scheduled water level check remaining «The control device for the load drive device 2 〇 output shuts off the water supply order to stop the water supply. The material in the water tank 3 is formed in the through hole 2 of the same age 2, for receiving It is absorbed by the washing in the rotating drum 1, and the water in the =3 is reduced (4). Therefore, the water supply for replenishment is performed in the same manner. Since the control operation is started, the washing step can be started, and the control circuit output is started. The control command of the rotary rotation rotation '7 phase 1 repeats the first! agitation control operation for a predetermined time, and the fl = Γ is rotated in the positive direction at a predetermined rotation speed for a predetermined time = after the movement 'stops the predetermined time rotation After the driving = speed is rotated in the reverse direction for a predetermined time, the pre-_ operation is stopped as a cycle. The predetermined rotation is arrested:: the feeding protrusion 6 at the plurality of positions on the inner wall of the rotating drum 1 The rotation speed of 1 is lifted, and the rotation speed of the action under the weight of the Aduolo is: the slap cleaning effect of the knee-washing object can be generated by the lifting of the singularity, and by = The sputum can produce a wash (four) towel that allows the dirt to self-absorb the water containing the detergent. The only one that is in contact with the smashing = 6 will be pulled out, and the position of the wire is interchanged. When the rotation=twisting speed is slower than the predetermined rotation speed, the lifting of the protrusion 6 may fail: the object 'when the rotating speed of the rotating drum 1 is faster than the predetermined rotating speed, the influence is too large', so the laundry being lifted is not Will fall due to its own weight. Furthermore, by inverting the rotating drum than the rotating side 13 1277677, it is possible to suppress the distortion of the laundry and to make the position interchangeable. Since the flapping cleaning effect of dropping the laundry is affected by the amount of laundry contained in the rotating drum, it is a preferred control method to change the predetermined rotational speed with the amount of the laundry. That is, as described above, the amount of laundry in the rotating drum has been detected for the amount of cloth detected by the farmer.

By spreading to the exhibition ρη '^, the block-shaped laundry 7Τ is in an unfolded state, and after moving to the rotation for a predetermined time, the detachment is rotated and the object is stopped at the stop. . By the movement of the *y in the rotating drum of the valley, the action of spreading and falling due to the attachment is carried out, and the washing of the 14 1277677 object causes a change in the positional movement and shape, so that the effect of the tapping cleaning is more effective. By the rotation control scale, the control operation of each of the stirring control operations of the above-mentioned 2nd is repeated and the required time is repeated, the laundry is exchanged in the front and rear positions in the rotary drum 1, and the stone 5 is used to achieve the action of the flapping and cleaning of different actions, and even if the rotary drum is obliquely arranged 'It also does not reduce the cleaning performance, and can apply equal cleaning power to all the strips. After the completion of the washing step described above, the control device outputs a control command for opening the drain valve η to the load driving device 2, and performs a control operation for discharging the water in the drain tank 3. The control unit 16 further rotates the drive circuit 5 to rotate the drive motor 5 at a high speed to remove the dehydration control command for the washing material 1 ^ a, and then performs a dehydration operation after the washing step. After the dehydration operation for a predetermined period of time, the control is turned off to close the row η' to open the water supply_ supply new self-boring water into the water tank 3, and start washing the cattle for 15 steps. In the washing step, the stirring and finening of the driving, /minor, and the direction of reversal are also performed, and the washing step and/or the second stirring control operation are performed in the same manner. (4) - Ground hunting and swapping the position of the washing material to make a tapping > The monthly washing action is applied to all the washings 2 unevenly (4). For example, if there is a washing 20 such as _ lion, then, f will::, after each washing step, the dehydration operation - water, and the dehydration operation in the second washing step is dehydrated cattle / The dehydration operation includes the aforementioned washing step, and is carried out by rotating the water-repellent cylinder at a high speed to self-wash the dehydrated surface of the dehydrated dewatering water. In order to carry out the dehydration operation in each step 15 1277677, the laundry must be uniformly attached to the inner wall of the rotary drum 1, and the water contained in the laundry is discharged from the through hole 2 to the water tank 3 by centrifugal force. within. When the laundry is deflected in the rotating drum, not only the dehydration cannot be smoothly performed, but also the rotating drum 1 is shaken or vibrated due to the difference in the center of gravity. Therefore, the dehydration start operation is started at the start of the dehydration operation. The control sequence of the first to third steps will be sequentially described below for the control sequence of the dehydration operation. Fig. 5 is a view showing the first control sequence of the start operation of the spin-drying operation in the control unit 16. Further, the number of each display sequence, S1, S2, ..., etc., is the number of the stage control sequence, which is the same as the number used herein. After the start of the dehydration operation, an initial determination value (S1) for determining whether the cloth balance is good or not is set, and after the number of determination repetitions (N = 1) is initialized (S2), the drum drive motor 5 is started to reach the first predetermined rotation speed (for example, 9〇/min) (S3). The time required to start the drum drive motor 5 to reach the first predetermined rotational speed is controlled based on the data detected by the 15 cloth amount detecting means 27 and memorized in the control unit 16. As shown in Fig. 6(a), when the amount of the strip is large, the rotational speed of the drum drive motor 5 reaches the second predetermined rotational speed (e.g., 4 rpm) at the first predetermined time t1, and reaches the second The rotation speed is maintained during the period before the predetermined time t2, and reaches the second predetermined rotation speed at the third predetermined time t3; when the laundry is less than 〇$, the control makes the second reservation as shown in the sixth (b) diagram. The time (t2 to t3,) from the time t2 to the first predetermined rotation speed is shortened. By this control, the centrifugal force applied to the laundry will be greater than the gravity, and the laundry is easily formed in a state of being attached to the inner wall of the rotary drum 1. If the washed article is attached to the inner wall of the rotary drum 1 equally, then 16 Ϊ 277677

The control device 16 switches the switching elements 23a to 2 to open and close according to the pulse input, and controls the energization of the i-th ring 5a, the second coil brother, and the third coil 定子 of the stator, and the first coil a The magnetic field generated by the second coil 5b and the third coil 5c rotates the rotor. The switch components 23 & 23 〇 and 236 are respectively controlled by pulse width modulation (1 > side), and the number of revolutions of the rotor is controlled by controlling the energization rate at a predetermined repetition frequency. The number of revolutions of the control unit 16 is controlled by the PMW control switching elements 23a, 23c, and 23e, and the number of revolutions of the dice is calculated by the pulse periods outputted by the devices 21a, 21b, and 21c to rotate the rotor by a predetermined number of revolutions. Therefore, in the state where the rotational speed of the rotary roll = 1 is at a predetermined rotational speed, if the pulses detected = the vertical devices - 2a, 2b, and (1) are not output at predetermined intervals, the occurrence is determined to occur. The rotation is in the read state, that is, the attached state of the laundry is poor, and the cloth balance is poor. Therefore, by setting the change range of the drum drive: the speed of the A-turn to the judgment value of the cloth balance, the unbalanced state of the knee-washing material in the special drum 1 can be checked. 17 1277677 If the state of uneven rotation is determined in the above-mentioned cloth balance determination, that is, the laundry is biased to η with a magnitude of seven m ^ ^ ^ ^ 1 , then the control (4) fine rotation (S5) ' Determining whether the repeated gamma has reached the number of times of the pre-twisting (for example, N==l6), and determining whether the number of repetitions N is less than the first pre-N=8) (S7), if not The number of people (for example, '10 times the number of intestines (S9), and returns from the sequence of the steps to start, and then perform the operation again. In the other aspect, the above-mentioned determination of the number of repetitions N (S7), the number of repetitions has reached the second When the predetermined number of times is changed, the determination value is changed, the number of determination repetitions N is incremented by one (S9), and then the sequence from the start of the step is returned, and the startup operation is performed again. Thus, when the number of repetitions reaches the second predetermined number of times, the cloth is balanced. When the determination value of the determination is changed to a judgment value having a larger allowable range, the dehydration operation is started even if there is a little imbalance, and the dehydration operation is less likely to occur halfway through the stop 15 . After repeating the above operation, if the cloth is judged in step S4 If the balance is good, then the number of repeated decisions is N. If it is 9 or more, it is judged (sii), and if the number of repetitions is not 9 or more, the determination value is not corrected, so the dehydration operation (S14) is performed at a predetermined dehydration rotation speed (for example, 900 rpm) to make the laundry On the other hand, if the number of repetitions is 9 or more in step S11, the determination value of the cloth balance determination is corrected for the expansion allowable range, and the laundry in the rotary drum 1 is biased to one side, so that vibration is likely to occur. Therefore, the dehydration rotation speed is set to be the second dehydration rotation speed (for example, 800 rpm) which is smaller than the predetermined dehydration rotation speed (S12), and the heart time is moderately extended with respect to the dewatering capacity of 18 1277677. (si3), the dehydration operation is performed (in addition, even if the judgment value is corrected in step 8 so that the allowable circumference of the cloth balance determination is expanded, and the balance of the cloth is not well balanced in step 4, it is determined whether or not the number of repetitions N is reached. After wearing two times, the number of times (for example, 16) is judged, t indicates that the repeated start operation has not improved the washing state, and the state of the yarn is complicatedly entangled, and the sound is made by electrons. An abnormal report is issued to urge the user to cancel the winding of the temple (_. Although not riding at this time, (4), the person who cancels the winding is 10 15 20, and the opening and closing of the door body 7 can be judged, so that the opening and closing of the door body is detected. , reset the number of repetitions N and start the operation again. ▲:: The determination of the balance of the cloth mentioned above in red, in the steps of washing, washing, dehydration, such as flute ^ Yan ~ one, «such as the 4th The drawing is not performed, so the determination of the cloth balance is performed in the dehydration operation in each step. When the first predetermined rotation speed is started, the rotation driving direction of the rotary drum 1 can be repeated with each repetition. Therefore, since the direction of the force applied to the washing article is different, the state in which the washing materials are entangled can be easily eliminated. As described above, according to the present invention, a drum type washing machine can be provided. When the cloth is not judged to be in good balance, the start operation of the dehydration operation is repeated a predetermined number of times, so that the washing material (four) of the rotating roller (four) is easily changed. Even if the washings are intertwined, they can be easily eliminated by repeated repetition, and the washings are complicatedly entangled with each other, and the initial determination value cannot be determined as a good balance, and the initial determination value is changed. In order to allow the change of the range width to be judged, even if there is a point imbalance, the 19 1277677 start dehydration operation is performed so that the dehydration operation does not stop halfway. In addition, the abnormality reporting device performs the abnormality report, and even if the entanglement of the laundry cannot be cancelled by the control operation, the user can be abnormally reported to urge the user to perform the unwinding process. At this time, the control dehydration operation is performed on the rotation. The speed is performed at a second dehydration rotation speed which is smaller than the predetermined water rotation speed of 5, so that even if there is a slight imbalance, the dehydration operation can be performed, and the steps can be smoothly performed after each step of washing and washing.
