The object of the present invention is to provide a fully automatic washing machine with uniform dehydration rate and low noise during dehydration operation. [Means to Solve the Problem] The first feature of the present invention is to sequentially shift a plurality of constant-speed dehydration operations that increase the number of revolutions and maintain a predetermined number of constant-speed dehydration operations from a low speed to a high speed. In a fully automatic washing machine that controls the dehydration operation by gradually increasing the number of revolutions to the maximum number of dehydration revolutions, if the number of revolutions is detected by the detection means that reaches the maximum number of dehydration revolutions, the number of instructions is set by the control means. 0 FF for a short period of time when the current is supplied to the single-phase induction motor, and then 0 FF is reached until the set number of revolutions of the highest dehydration revolution is reached. The current is supplied to the single-phase induction motor. The highest dehydration speed. The second feature of the present invention is between the short period of time when the setting of the number of revolutions and the detection means reaches the maximum dehydration number of revolutions and the setting of the control means to set a short time for the energization of the single-phase induction motor. After reaching the set number of constant-speed dehydration revolutions, FF is supplied to the energization of the single-phase induction motor, and the OF F and ON of this energization are repeated to maintain the aforementioned constant-speed dehydration revolutions in the full-automatic washing machine. Phase control for increasing the energizing amount of the energizing cycle in sequence before moving to full energization without energizing the energizing cycle of the AC power supply. m Hal HI ^^ 1 ^ 11 n ^ i--eJ (Please read the notes on the back before filling out this page) This paper size applies to China National Standard (CNS) A4 (210X297 mm) · 5-Economy Printed by the Consumer Standards Cooperative of the Ministry of Standards of the People's Republic of China A7 ____B7___ V.

When the signal is transmitted interactively, the motor 8 will perform forward and reverse rotation. The forward and reverse rotation from the motor 8 is shown in Figure 1. The rotation transmission method is forward and reverse. During the forward and reverse rotation, the cloth volume detection judgment is performed; that is, in the forward and reverse rotation of the motor 8 during inertial rotation after 0 FF is energized, a reverse voltage is generated at both ends of the driving capacitor 8 a; The electromotive force is converted into a more direct-current rectangular wave pulse by using a photosensitive, three-level AC switch coupler 38, and the inverter 39 is converted into a direct-current rectangular wave. The signal is sent to a central processing circuit to measure and determine the amount of distribution. Because the resistance added to the stirring blade 6 is different according to the number of clothes, the attenuation state of the inertial revolution will be different; because the difference will be n---I · II I ....... ^ 1 · T ^ i -I— —8- —II Τ »(Please read the notes on the back before filling out this page) This paper size applies to China National Standard (CNS) A4 specification (210X297mm) -8- Ministry of Economic Affairs The Central Bureau of Standards, Shellfish, Consumer Cooperative, Du printed equipment, A7 ____B7____ _ V. Description of the invention (6) The time difference between the aforementioned DC rectangular wave pulses is expressed, so it can be judged that there are as many clothes as possible. After the cloth quantity is judged, the cloth quality is judged; that is, after the cloth quantity is detected and controlled, the signal from the regulator is energized to the water supply solenoid valve 2 4 and the water is supplied to the laundry and dehydration tank 5; once the water level sensor 13 When it is detected that the water supply reaches the predetermined position, the motor 8 performs forward and reverse rotations similar to the cloth volume detection control, and sends a signal (Td to the central processing circuit 34) of the voltage across the terminals of the driving capacitor 8a of the generated back electromotive force. (Figure 4): Next, use the cloth detection control to determine the water level, and supply water in the laundry and dewatering tank 5. Once the water level sensor 3 detects the water supply to the cloth determination water level, and the cloth detection The control is the same, the motor 8 performs forward and reverse rotation, and sends a signal (Ting 2) of the voltage between the terminals of the driving capacitor 8 a of the generated back electromotive force to the central processing circuit 34 (Figure 7). After Ding 2 ’s signal changes, the cloth quality is judged. After the cloth quality inspection is completed, the washing process is performed; after the washing process is completed, the signal from the central processing circuit 34 is energized to the drain valve 15 for the drainage process; once it is finished Drain the stroke, then energize the motor 8 to rotate the washing and dewatering tank 5 and use its centrifugal force to take out the washing liquid contained in the clothes in the washing and dewatering tank 5; once at this time, the washing and dewatering tank 5 is rotated continuously from the drainage α The amount of water in the 16 drainage will be more than the amount of water from the washing and dewatering tank 5, and the washing liquid will be stored in the outer tank 4. Due to the good agitation, the washing and dewatering tank 5 bubbles accumulated in the washing liquid in the outer tank 4 will increase greatly. Due to the surface tension of the bubble, the rotation of the washing and dewatering tank 5 is hindered, so the current flowing through the motor 8 is increased, which generates the strange smell of the motor and the occurrence of smoke.

Problem of invention description (7) (prevents foaming of laundry detergent) * In order to prevent foaming of laundry detergent, the dehydration operation pattern shown in Fig. 6 is implemented. The dehydration operation Repeating the pattern while increasing the number of revolutions A plurality of constant-speed dehydrating operation and a predetermined number of operating water maintained at a predetermined transfer time sequentially shifts from the low speed to the high speed while the number of revolutions is increased stepwise increase until the highest number of revolutions dehydration. In this dehydration operation scenario, the fixed-speed dehydration operation is separated from the two vibration resonance points (a, b), and the vibration resonance point (a, b) is passed during the accelerated dehydration operation; then, the constant-speed dehydration operation is performed as follows As shown in Figure 6, the set number of revolutions to reach the constant speed dehydration operation. If the number of revolutions detection device 20 detects, it will turn on the power of the motor 8 OF FTa seconds (2 ~ 3 seconds); if Ta Second, the ON motor 8 is energized and continuously energized until it reaches the set number of revolutions of the constant-speed dehydration operation. The energization time may be 1 to 2 seconds indefinitely; repeat this OFF and ON of the energization to maintain the constant-speed dehydration operation. Because the constant speed dehydration operation is to set the number of revolutions from low to highest, the above-mentioned methods are performed; then, these constant speed dehydration operations are set to D: seconds, T2 seconds, T3 seconds, Tn seconds and the overall time. The aforementioned obstruction to laundry foaming is solved by draining the washing water dewatered by the speed increasing dewatering operation to the constant speed dewatering operation. In addition, the constant-speed dehydration operation changes the number of repetitive rotations of FF and ON that are energized up and down. The overall speed is constant, and there is no practical obstacle to the release of the detergent foam.

Description of the invention (8) Fig. 7 shows the phase control when the ON and FF of the constant-speed dehydration operation are ON; the current is ON due to the constant-speed de-operation; FF and ON are extremely short cycles of about 2 to 3 seconds. Repeatedly, the abnormal noise caused by increasing the instantaneous acceleration force to the motor when the current is 0 N is very harsh; especially the amount of fixed washing is very small. When the set number of revolutions is low, the rotating inertia force of the washing and dehydration tank will be small. Even more remarkable: due to this abnormal noise reduction can be used for phase control. That is, the reduction range of the supplied AC power supply cycle is sequentially reduced to move to full power; the initial reduction range is 90%, followed by the reduction range 2 is 70%, and the second reduction range 3 is 60%. 2. The final reduction range 4 is about 20% to slowly increase the power-on period, and then perform full power-on. In this way, before the current is switched to the full power that is not deleted, the power of the power cycle is sequentially increased for phase control, because when switching from FF to 0 N, the acceleration force of the full power cycle is not generated in the motor in one go. , So you can reduce the abnormal sound. Fig. 8 is a flowchart showing the overall operation of the washing machine. In step 51, the amount of clothing to be subjected to the aforementioned cloth amount detection control is determined; then in step 52, the amount of clothing to be subjected to the aforementioned cloth quality detection control is determined; as the cloth amount and the cloth quality are determined, the aforementioned set number of revolutions N, set At time T, determine the set number of revolutions η (steps 53, 54, 55). Go to step 56. Perform the washing cycle. After the washing cycle ends, perform the draining cycle (step 57). Then, in step 58, the motor 8 is powered on. 5 9, 6 0 — Detect the device by the number of revolutions 2 0 Turn the motor 8 to the set number of revolutions while detecting the number of revolutions IIIIIII — Order IIIII (Please read the precautions on the back before filling this page) This paper Standards are applicable to Chinese National Standards (CNS) A4 specifications (210X297 mm) -11 Printed by the Consumers' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7___ V. Description of the invention (9) Up to N ·, reaching the set number of revolutions n in step 6 1 The motor 8 is energized within Ta seconds and the motor 8 is energized again to the set number of revolutions N (steps 6, 2, 63, and 64); the operations of steps 62 to 64 are repeated within T seconds (step 65). Step 66; Step 66 is performed to the end of η times 6 1 ~ 6 5 So far, if it is finished, go to the next step. However, when the laundry is mostly on one side or the like, the vibration of the laundry / dehydration tank 5 will not increase beyond the vibration resonance point b, and even outside the vibration resonance point, there is a possibility that the laundry detergent may be prevented from foaming. This correspondence is as follows. Measure the time t1, ..., tn until the set number of revolutions is reached. Even if the above t1 '.. tn exceeds the set time, the next set number of revolutions cannot be reached. A trip. After the dehydration stroke is stopped, the washing materials to be fed with water will be reduced to one side, and the drainage will be sent to the dehydration cycle again. The following describes the maximum dehydration operation at the constant speed dehydration operation to the set number of revolutions and its ON and OFF. Because the dehydration rate is determined by the maximum dehydration operation speed, it must be connected to the AC power supply voltage fluctuation The maximum dehydration speed is still the same when the number is different; that is, the set number of revolutions to reach the maximum dehydration operation. If the rotation number detection device 20 detects, it will turn off the power of Ma · Da 8 for about 2 seconds; motor 8 It will decelerate. If 2 seconds elapse, the motor 8 will be turned on, and the connection will be turned on until it reaches the set number of revolutions for the maximum dehydration operation. Repeat the power off and on for the specified time to implement the paper standard. CNS) A4 size (210X297mm) -12 · (Please read the notes on the back before filling out this page)
