As shown in the figure, a water tank 53 is supported in the washing machine body 57 by a suspension structure, and a rotating drum 5 is provided in the water tank 53. A plurality of through holes are provided on the inner wall of the rotating drum 51. The suspect rotation drum μ is driven by the rotation of the drum driving motor, and is detected on the front side of the washing machine body π. There is a door 54 that can be opened and closed freely, and the door 54 is opened to pass through the front opening of the water tank 53 and the front of the rotating drum 51. In the opening part, the laundry can be put into or taken out of the rotary drum 51. 15 20 Open the aforementioned door body 54, put the laundry into the rotary drum_, and then put in the detergent, and supply water to the water tank 53. The supplied water maiden also supplies a large amount of water to the rotary drum 51 through the through-hole 52 '. By the drum drive motor 55, the rotary drum 51 is driven to rotate at a predetermined rotation speed, and the laundry contained in the rotary drum 51 is cleaned. The semi-protrusions 56 provided on the wall of the rotating drum M ^ are hooked, lifted in the direction of rotation, and dropped at an appropriate height ^ to apply a lap washing action to the silk, and perform washing by this = after the washing step After the washing material is discharged, the material supply 2 is subjected to the washing step. After the washing step is completed, the money rotating drum μ is rotated at a high speed to perform the dehydration step. These steps are automatically performed according to a predetermined control sequence. 5 200536982 (Refer to Patent Document i). In a roll-type shoulder washing machine, when the rotary drum 51 is in a stationary state, the laundry is biased toward the lower part of the rotary drum 51. The self-rotating drum is performed after the washing step and the washing step. 51, drain the water, and then rotate the rotating drum 5 51 at high speed to dehydrate the laundry by centrifugal force. If the laundry is still on one side, the center of gravity of the rotating drum 51 will be in an unbalanced state. Large vibrations cannot perform normal dehydration operation. The drum type washing machine in the foregoing prior art is controlled to perform a cloth releasing step of rotating the rotary drum 51 at the first rotation speed, and the speed is increased from 10th to 10th 2 The cloth balance step of the rotation speed, the preliminary dehydration step for causing the rotary drum 51 to rotate the preliminarily laps at the third rotation speed, and the balance judgment step for detecting the cloth balance at the second rotation speed after the preliminary dehydration step, and then [Patent Document 1] Japanese Patent Application Laid-Open No. 10-201985 (Pages 3 to 5 and Figure 1 15), [Summary of the Invention] Summary of the Invention However, in the conventional dehydration control, it is complicated and time-consuming to actually perform dehydration operation and other control operations. Therefore, there are problems of increasing costs and increasing the time required for laundry in vain. 'Sometimes there is a rope-like article or a long ribbon-shaped temple on the laundry. In the washing and washing steps, the laundry will be complicated, such as A, 丄, and this cannot be controlled by control operations. Cancellation. Since there is no other way than urging the user to unwind and wash the article at this time, there is a problem that the operation is stopped when the imbalance of the laundry is unresolved. The purpose of the present invention is to provide A drum type washing machine is controlled so that the dehydration operation performed after each step of washing and washing can be smoothly performed, and the same operation can be performed when the imbalance of the laundry cannot be solved. Means to solve the problem In order to achieve the foregoing object, the drum type washing machine 10 15 20 of the present invention is a rotating drum whose central axis of rotation is located in a relatively horizontal direction or a direction inclined horizontally; a water tank is elastically supported on the pivot of the washing machine The above-mentioned rotating drum is provided inside and inside; a drum driving motor is used to / rotately drive the above rotating drum; and a control device is used to control the front fan driving motor to rotate, and the aforementioned control device is in each step In the off-line operation, the aforementioned rotating drum is activated until the laundry is easily attached to the first predetermined rotation speed on the inner wall thereof, and a predetermined initial judgment value ^ is used to determine whether the laundry is evenly attached to the cloth on the inner wall. The balance judgment uses the cloth balance judgment based on the aforementioned initial judgment value. If the balance is not good, the operation to reach the cloth judgment is repeated. When the number of levels equal to a predetermined number of times, the initial judgment value is changed. In order to allow a larger range to change the judgment value, and repeatedly reach the aforementioned cloth balance judgment operation: When the initial judgment value or the change judgment value judges that the balance is good, then the rotating drum is controlled to rotate at a dehydration rotation speed. According to the structure, the cloth balance judgment is not judged to be flat. The starting operation of the human dehydration operation makes the state of the laundry in the 2 good rotating drums more capacity. Even if the county is only 7 200536982 entangled state, it can be easily lifted by this repetition. When the laundry is intertwined with complicated matters, and the initial judgment value cannot be judged to be in a well-balanced state, the initial judgment value will be changed to a change judgment value with a wide allowable range. Even if there is a -point imbalance, dehydration will start. Operation, so dehydration operation 5 is not easy to stop halfway. / In the structure, the aforementioned control device performs control when the number of repetitions according to the aforementioned change determination value reaches a predetermined number of times, and uses the abnormality reporting device for abnormality reporting, even if there is a control operation that cannot resolve the entanglement of the laundry, Anomaly reporting can be performed on the user to urge the user to perform a 10-wrapping treatment. In addition, when the foregoing control device determines that the cloth balance is good based on the change determination value, it controls the dewatering rotation speed and performs the dewatering operation at the second dewatering rotation speed, and the second dewatering rotation speed is less than the initial value based on the month. The judgment value judges that the predetermined dewatering rotation speed of 15 rotations when the cloth balance is good. The strip washing object will not stop the dehydration operation due to the control operation under the unbalanced unresolved condition, and the dehydration operation will be performed even if there is a little imbalance. Since the dehydration rotation speed at this time is reduced to the second dehydration speed and the dehydration capacity is reduced ', the dehydration time is controlled to be extended, and the dehydration condition is approximately equal to the dehydration rotation speed. 20 Furthermore, when the control device reaches the first predetermined rotation speed, the control device controls the rotation driving direction of the rotating drum to be changed every time it repeats. Because the action direction applied to the laundry is different, the laundry is entangled with each other. The state is easily released. Effect of the present invention 8 200536982 According to the present invention, in the dewatering operation after each step of 收: collection / ^ washing, the distribution state of 姝 姝 in the rotating drum as the laundry distribution state is determined as the cloth balance, as It is judged as a well-balanced sundial. It will repeat the start operation of entering the dehydration operation for a predetermined number of times, so that the state of the laundry in the rotating tumbler is difficult to change, and the objects can intertwine with each other. Operation becomes easy to resolve. And when the laundry is entangled with each other, and the cloth balance cannot be reached at the initial judgment value and it is judged that the balance is good, the initial judgment value of the face and the mouth is changed to a change judgment value 17 with a wide tolerance range. Start the dehydration operation, because the water operation is not easy to stop halfway. The muscle 10 15 controls the dehydration operation performed at this time, so that the straight dehydration rotation speed is less than $ ', the second dehydration rotation speed of the top dehydration rotation speed', so even if there is a little ... 5 imbalance, the dehydration operation can be performed. . In addition, by controlling the abnormality report of the dream department, it is possible to report the abnormality to the user even if there is a control operation that cannot be undone; even if there is a entanglement of the object, the user can be urged to perform the unwinding process. [Embodiment] The best form for implementing the present invention. The first figure shows the main structure of a drum-type washing machine in the embodiment. The water tank 3 is supported in the washing machine body 9 by a hanging structure (not shown), and in the water tank 3, A rotating drum 1 having a bottomed cylindrical shape is arranged, and the rotation axis direction of the rotating 20 drum 1 is arranged to be inclined with respect to the horizontal direction. The rotary drum 1 is disposed in the water tank 3, and its bottomed cylindrical opening side is located on the front side of the washing machine body 9, and the bottom side is located on the back side of the washing machine body 9, and the rotation axis direction is from the front side. It is inclined downward toward the back side, and is rotated by a drum drive motor 9 200536982 mounted on the back of the water tank 3. An opening 8 is formed on the front side of the water tank 3 for taking out or loading laundry into the rotary drum 1. The inclined surface forming the front side of the washing machine body 9 is provided with an opening facing the opening 8 and can be opened and closed freely. The door body 7. Since the door opening portion 8 is opened upward and the door body 7 is provided on the upwardly inclined surface, by opening the door body 5, the operation of taking out or loading laundry in the rotary drum 1 can be easily performed, and the door can be opened by A part or all of the body 7 is formed of a transparent body, and the inside of the rotary drum 1 is easily seen from the outside. When the rotary drum is arranged obliquely like the aforementioned structure, it has easy to carry out the operation of removing or loading the first product, and the water accumulation 2 supplied to the rotary drum 丨 the back side, which can obtain a deeper water storage state with less water. Benefits like savings = water. On the contrary, the laundry items stored in the rotating drum 聚集 will gather in the lower part of the bottom surface side. For the individual position of the interchangeable laundry items = the action of the cloth to apply the cleaning force to all knees or the dehydration operation makes it difficult to wash. The problem that the strips are evenly attached to the inner wall. In this case, the protrusions 6 are blended by a plurality of positions provided on the inner wall of the rotating roller ^: • Control the rotation driving of the rotating drum 1 generated by the driving motor 5 due to the rolling, so that the positions of the laundry are interchanged as a solution The solution to this problem. Caisei stirring protrusion 6 is formed to have a top system formed by the direction of the wheel toward the predetermined: and = 20 extends into a long shape, and the aforementioned mixing protrusion 6 = oblique angle direction when the cylinder 1 is rotated, it is easy to deflect: 1 in The effect of rotating the tumbler to move the product to a higher position / the lower position in the decay chamber 1 is installed with the aforementioned ridge 6: number position 200536982 position, so even if the rotating drum 1 is arranged inclined, the laundry will not be biased It can be fully stirred on the lower side of the rotating drum 1, and the position of the laundry is well interchanged and mixed, and the cleaning effect will not be reduced. In addition, when there is little washing, the amount of washing liquid is also small. In order to make all the washings immersed in 5 'bag-like evils', it is necessary to stir so that the positions of the washings are fully interchanged. Fully interchangeable, so that the cleaning will not be uneven and the cleaning power will be improved. Fig. 2 shows the control structure of the drum-type washing machine having the aforementioned structure, and the control device 16 for controlling the operation of the drum-type washing machine is configured to control the operation of the drum drive 10, the motor 5, the water supply valve 2 and the drain valve Π. The input setting section 17 and the display device 18 provided on the surface of the washing machine body, when the operation process of input selection from the input setting section 17 is displayed on the display device 18, the status and operation status of the selection are displayed, and the control device 16 is based on user input. The control sequence corresponds to the operation sequence to control the drum drive motor 5, the water supply valve 12, and the drain valve. The operation of the off-loading drum type washing machine which is operated under the control of the control | set 16 is described below with reference to FIGS. 1 to 3 as follows. Open the door body 7 to put the laundry in the rotating drum 1, and put the detergent in the α 4 agent input port of the water supply 15, and then press the power on button 1 on the operation panel as shown in Figure 3 to open The power supply is selected by the process selection. Pressing the 20 button 17d to input the selection of the operation process corresponding to the type of laundry, and then pressing the start / pause button to input the operation start instruction, the operation control of the control device 16 is started. The operation of the drum type washing machine is basically performed according to the procedures of the washing step, the washing step, and the dehydration step, and when a drying function is provided, the drying step can be performed at will. 11 200536982 First, the control device 16 outputs a control command to the driving circuit 22 to cause the rotary drum 丨 to rotate and drive at a predetermined rotation speed to detect the amount of laundry put into the rotary drum]. By the drum driving motor 5 controlled by the driving circuit 22 to drive the rotary drum i to rotate, the cloth amount detecting device 27 can detect the amount of the laundry by the drum driving motor 55 depending on the load state to which the amount of laundry is subjected. That is, the drum driving motor 5 is constituted by a brushless DC motor. As shown in FIG. 2, the driving circuit 22 controls the switching of the switching elements 23 a to f of the inverter 23, and the inverter 23 controls the drum driving motor 5. The three-phase coils 5a, 5b, and 5c of the stator are energized. The DC power supplied to the aforementioned converter 23 is a DC power generated by rectifying a commercial power 28 with a diode bridge circuit 29, a current-resistant coil 30, and a smoothing capacitor 31. Since the load status of the drum driving motor 5 is approximately proportional to the input current, the negative detection device 24 can use the current detection circuit 26 to connect the two ends of the resistor 25 arranged in series with the circuit supplying the DC power of the converter 23 The voltage is used to detect the value of the input electric power 15 μ, and the day-to-day measurement device 27 detects the amount of the articles washed in the rotating drum 1 based on the current value. Since the amount of laundry detected by the cloth amount detecting device 27 is used for a control operation described later, the amount of laundry is stored in a memory provided in the control device 16. Next, the control device 16 outputs a control command to the load driving device 20 to open the water supply valve 20 12. The water supply valve 12 is opened and the tap water is supplied by a water supply officer connected to the water supply unit 15. This tap water is supplied to the water tank 3 while being mixed with the detergent put into the water supply unit 15. The amount of water supplied to the water tank 3 is set in accordance with the amount of laundry detected by Brie 4 Huanzhi 27. The water supply time is set. The water supply amount in the water tank 3 is detected by the water level detecting device 19, and once it reaches the predetermined water 12 200536982 丨 Wada non-sensing device 19 controls the control signal, whereby the control device stops the water supply by pre-determining the command of the water level. Supply__ water supply_ The through hole 2 of the cylinder 1 is for the water contained in the rotation to pass through the water level formed in the rotation roller _ and will be lowered 'due to operation.

Controlling the rotation ^ Moving the drum 丨 Simple phase weight Wei Xingdi added to the mix = The control of the drop control operation _ Speed is rotated in the positive direction ^ 1 rotation of the fixed time After driving, stop the _timed rotation drive, and then follow the predetermined speed of turning towards the shirt for a time _ drive, stop the rotation drive control operation at the predetermined time as a _ cycle. The predetermined rotation speed is a rotation speed at which the washing protrusions 6 hooked on the inner wall of the rotary drum are lifted by the rotation of the rotary drum 1, and the weight is greater than the centrifugal height. . By dropping the rapture first, the object can be slapped and cleaned, and the cleaning effect can be achieved by falling. In addition, among the overlapping strips, only those who come into contact with the search protrusion 6 will be pulled out. When the rotation speed is the same as the speed rotation speed of 1, the ridge protrusion 6 will not be able to lift the laundry. 'When the rotation speed of the rotation speed is faster than the predetermined rotation speed, repeated violations can cause the dirt to self-absorb water containing clean water. At 20 o'clock, the influence of centrifugal force will be too great, so the lifted secret will not be affected by its weight. Furthermore, by reversing the direction of rotation of the rotating drum 丨 13 200536982, the distortion of the laundry can be suppressed, and the interchange of positions is effective. 10 15 20 Because the washing and washing action of lifting and dropping the laundry will be affected by the amount of laundry contained in the rotating drum, changing the predetermined rotation speed with the amount of laundry becomes a better control method. That is, as mentioned above, because the amount of laundry collected in the rotating drum has been detected and memorized by the cloth amount detection device 27, when the amount of laundry is more than a predetermined amount set in advance, the control device = will slow down Predetermined rotation speed. On the other hand, when the memorized laundry is turned to a predetermined predetermined amount, the controller 16 will speed up the scheduled rotation. Although it lacks the required knee-washing time to repeat the second control operation, please do n’t, The effect of correcting the H return position has been achieved, but after the first foot is required for a long time, then the first mixing control operation can be performed. The control operation can be driven by rotating the rotary drum 1 to repeat the predetermined time. Stop the scheduled time faster than during the first operation. % Advance: After the rotation is driven for a predetermined time, the dry, #W, and the drive are followed by the predetermined rotation in the same direction as the forward direction = the reverse direction is performed for a predetermined time II; the medium speed: r is used as: the cycle. The centrifugal force generated by the second stirring control operation and the speed at which the strips H are produced by rotating the rotary drum 1 and washed on the inner wall of the spinner. By spreading out, it can decay on the inner wall of the same 1, so that the block-shaped laundry can be rotated for a predetermined time: ′, and the laundry moved above the rotating drum 1 stops on the wall and falls. By Z ′, it will be separated from the rotating drum rotating due to inertia. 3 Perform the action of spreading and falling due to _. The washing operation 200536982 will change the position movement and shape of the object, making the cleaning and washing effect effective. In addition, the time required for each of the agitating control operations of the aforementioned 丨 and 2 to take turns and repeat the time required, the front and back positions of the laundry in the rotating drum 1 are interchanged. 5 No: the action of patting and cleaning, and even if the drum is rotated : Department: It can be placed diagonally without degrading the cleaning performance, and the cleaning power is uniform for all the strips. 10 15 20 After the above washing step is completed, the control device drives the load 20 to output the open water _ command to perform the drainage control operation of the washing water in the drainage tank 3 which can be distinguished. ㈣The device 16 also outputs to the shaft circuit to rotate the driving motor 5 at high speed to remove the dehydration control command for the washing water contained in the silk, and performs the dehydration operation after the washing step. After performing the dehydration operation for a predetermined time, the control device closes the drain U 'and turns on the water supply unit 12 to supply new tap water into the water tank 3 and starts the washing step. In the washing step, the secret operation of driving the rotating drum to reverse in the forward and reverse directions is also performed. By performing the first stirring control fall and the seventh or second stirring control operation in the washing step, the same can be exchanged. The position of the laundry makes the tapping and cleaning effect be applied to all the silks all over the place to perform the washing operation without uneven production. After the month f ®, after the _ step, the washing step V is usually performed twice. After each washing step, a dehydration operation is performed to remove the water contained in the laundry. In the second washing step, The dehydration operation is the dehydration step. That is, the operation of money is carried out by including the aforementioned steps, and the money is removed, the rotating roller is rotated at the same speed, and the money is dewatered from the washing material. In order to ensure that the dehydration operation in each step 15 200536982 5 10 15 20 step is carried out, the laundry must be evenly attached to the inner wall of the rotating drum 1, and the water contained in the laundry must be separated from the through hole. 2 Shake out to sink 3. If washing; the strips are on one side in the rotary drum, not only can the dehydration not be performed smoothly, but also the rotary drum 1 will tremble or vibrate due to weight and poorness. Therefore, the dehydration operation is started to start the dehydration start operation. The control sequence of the dehydration operation will be described below according to the first to third control sequences. Fig. 5 shows the first control sequence of the starting operation of the dehydration operation in the control device I6. X, the number of each display sequence, S2 ..., etc. are the phase numbers of the sequence, which are consistent with the numbers used in this article. 1 After the dehydration operation starts, set the initial judgment value to determine whether the cloth balance is good or not (S1W). After the number of repetitions (N = 1) is initialized (S2), start the drum drive motor 5 to reach the predetermined rotation speed (for example, 9 〇rpm / ⑽) ⑽. The time required to start the driving motor 5 to reach the first predetermined rotation speed is controlled based on the data detected by the cloth amount detecting device 27 and stored in the control device 16. As shown in FIG. 6 When the amount of washing is large, the rotation speed of the drum driving motor 5 reaches the second predetermined rotation speed (for example, the rotary knife) at the first predetermined time, and the rotation is maintained for the period before the second predetermined time 12 and the At the third pre-set time, the oldest rotation speed is reached between 0 o'clock; when washed: when it is young, then as shown in Figure 6 (b), control is made so that the second pre-set time is just 2 to reach the speed of beating The time (t2 ~ t3 ') is shortened. By this control, the centrifugal force on the washing strip will be greater than gravity, which will easily cause the washing to form a state of being attached to the inner wall of the tumble drum 1. If the washing object is If it is evenly attached to the roll of the rotating drum 1, 16 200536982 "Τ roll 1 can rotate normally without rotation unevenness. Therefore, in the cloth balance determination (S4), it will be judged that the balance is good, and the control device can control the dewatering operation by rotating the drum drive motor 5 at high speed (S14 ), Dewatering from the laundry. The aforementioned cloth balance determination is performed by detecting the rotation unevenness 5 of the rotating drum 丨 to enter the lamp. As shown in Figure 2, on the stator of the drum drive motor 5 constituting the DC brushless motor, Position detection devices 21a, 21b, and 21c composed of Hall elements at intervals of 120 ° electrical angle are provided to face the permanent magnets with the rotor. The position detection device 2 is used for every 1 revolution of the rotor] ^ 21, 2] ^ The magnetic field of the aforementioned permanent magnet is detected, so pulse signals can be input to the 10 control device 16 at intervals of an electrical angle of 120 degrees. The control device 16 switches the switching elements 23a to 23f on and off based on the pulse input. The state is to control the energization of the i-th coil 5a, the second coil 5b, and the third coil 5c of the stator, and the rotor is rotated by the magnetic field generated by the first coil 5a, the second coil 5b, and the third coil 5c. The switching elements 23a, 23c, 23e is controlled by pulse width modulation (pwM) 15 systems, and the number of rotations of the rotor is controlled by controlling the energization rate at a predetermined repetition frequency. The control device 16 is controlled by PMW to control the switching elements 23a, 23c, 23e to The number of rotations of the rotor is calculated from the pulse periods output by the three position detection devices 21a, 21b, and 并使 and the rotor is rotated at a predetermined number of rotations. Therefore, if the rotation speed of the rotation = drum 1 is maintained at a predetermined rotation speed, if It is detected that the pulses of the 20 self-position detection devices 21a, 21b, and 21c are not output at predetermined intervals, and it can be determined that the rotating drum 丨 has a state of uneven rotation, that is, the state of the laundry on the inner wall is poor, and the cloth balance is poor. . Therefore, by setting the variation range of the rotation speed of the drum driving motor 5 as the judgment value of the cloth balance, the unbalanced state of the laundry in the rotary drum 1 can be detected. 17 200536982 Health: It is judged in Γ wide-spread balance judgment (S4) that the rotating drum 1 is in the state of hair == Γ, that is, the state of washing, then the control is installed with the same rotation! Rotate, for the number of times in Hungary, such as .16) _ = a certain number of times, then repeat the judgment _ yes) the right has not reached the first pre-M 8V #-4,1 ^ ^ brother 2 predetermined number of times (for example (N = 8) into the decision (S7), if no money is reserved, the county judges to repeat == plus 1 (S9), and returns to the order starting from step S3, and start again. In the judgment (S7), when it is found that the number of repetitions has reached the second number of times, the state value is changed (S8), the judgment of 10 is repeatedly increased by 1 (S9), and then the order of self-step is returned, and the start operation is performed again. . In this way, when the number of repetitions reaches the second predetermined number of times, the judgment value of the cloth balance judgment is changed to a judgment value with a larger allowable range. Therefore, if there is a point imbalance, the dehydration operation will still start, making the dehydration operation unlikely to happen halfway. 15 Stopping situation. After repeating the foregoing operations, if the cloth balance is judged to be good in step S4, • If the number of repetition judgments N is 9 or more is judged (S11). If the number of repetitions is not 9 or more, the judgment value is not corrected, so The dehydration rotation speed (for example, 900 rpm) performs a dehydration operation (S14) to dehydrate the laundry. 20 On the other hand, if it is found that the number of repetitions is 9 or more in step SU, the judgment value of the cloth balance judgment has been corrected to expand the allowable range, and the laundry in the rotating drum 1 is biased to one side, which is prone to vibration. Therefore, the dehydration rotation speed is set to a second dehydration rotation speed (for example, 800 rpm) which is smaller than the predetermined dehydration rotation speed (S12), and at the same time, relative to the 18 200536982 drop in dehydration capacity, the "Water_ ⑻3), riding dehydration operation (si4). 5

A predetermined number of times (for example, n = i6) is entered. When the number of times has been reached, it means that the state of the washings has not been improved by repeated startup operations. If the state of a certain domain has a complex state, the electronic sound or Synthetic sound recording compilation report, to unwind users and other situations ⑽). Although it is not shown at this time, the user can perform the unwinding process by using the door body 7 to make a judgment. Therefore, when the opening and closing of the door body is detected, the repetition number N is reset and the start operation is performed # times. In addition, during the dewatering operation, the aforementioned cloth balance determination is performed in each step of washing, washing, and dehydration as shown in FIG. 4, so the cloth balance is performed in the dehydration operation in each step. determination. In addition, when the first predetermined rotation speed is activated, the rotation driving direction of the rotary drum 丄 can be changed with each repetition. In this way, because the direction of the force applied to the washing object is different, it is easy to eliminate the state where the washing and riding are intertwined. As explained above, according to the present invention, a drum-type washing machine can be provided. When the cloth balance is not judged to be well-balanced, the starting operation 20 of the dehydration operation is repeated a predetermined number of times, so that the state of the laundry in the rotating drum is easily changed. Even if the laundry is intertwined, it can be easily eliminated by repeating it. When the laundry is complicatedly intertwined, and the initial judgment value cannot be judged to be a good flat state, change the initial judgment value to allowable. The range setting changes the set value, so even if there is a little imbalance, it still starts. 19 200536982 Start the dehydration operation so that the dehydration operation will not stop halfway. In addition, by using the abnormality reporting device for abnormality reporting, even if it is impossible to remove the entanglement of the laundry by the control operation, the user can also report the abnormality to urge the user to perform the unentanglement treatment. At this time, because the dehydration operation is controlled in the rotation The speed is 2nd dehydration rotation speed which is lower than the 5th dewatering rotation speed, so even if there is a little imbalance, dehydration operation can still be performed, and it can be performed several times smoothly after each step of washing and washing Dehydration action.
