Moreover, the control device 1 16 sequentially controls a series of steps of washing, washing, dehydrating, and the like. -6- 201100601 The conventional washing machine is configured as described above. The operation of this conventional machine will be described using the flowcharts of Figs. 5 and 6 . First, a description will be given regarding the washing step. When the washing step (S 1 00 ) is started, the opening and closing lid i is opened, and the laundry and the like are put into the washing and dewatering tank 104 (step S101). Then, the power is turned on to open step S102), and then the start switch is turned on (step S103), and the valve 1 17 is turned on (step S1 04). Here, the drain valve 108 is in the 0 state. Thereby, water is supplied to the washing and dewatering tank 104. Water level check 1 1 2 Check the water level (step s 1 05 ). When the water level has not reached the predetermined position A (No in step S105), the flow returns to step S105 to continue the water supply. When the water level reaches the predetermined water level A (Yes in S105), the water supply valve is closed (step S106), the supply is stopped, and then the motor 119 is started, and the pulsator 106 is rotated in the forward and reverse directions (S107). Thereby, the laundry is carried out. In step S108, it is judged that the pulsator 1 〇6 has started to rotate and Q has elapsed for a predetermined time. When the predetermined time has not elapsed (N 步骤 of the step)', the process returns to step S1 0 8. When the predetermined time has elapsed, S 1 0 8 Y e s ), the motor is turned off! 〇 9 (Step S 1 〇 9 ), Stopper 06. Thereby, the laundry step is terminated (step S丨丨〇). When the washing step not shown in Fig. 5 is completed, secondly, it is moved to the washing step shown. When the washing step is started (step S200), the drain valve 108 (step S201). Then, the clutch switching device inside the drive mechanism portion 1 is switched, and the brake of the dewatering shaft 105 is released (S2〇2). Thereby, through the dehydration shaft 丨05, the washing and dewatering tank 1 〇 4 washing step is turned into the water (the water supply is closed to measure the water, and the step water is held. Step S 1 08 (step stop pulse 6 is opened [1 step becomes In the case where the drainage is not completed (No in step S203) 'returns to step S203. In the case where the drainage has ended (Yes in step S203), the motor 1 is started. 9. Dehydration in the washing step as intermediate dewatering, and the washing and dewatering tank 104 rotates (step S204). Specifically, the laundry and dewatering tank 1 〇4 are rotated by about 700 to 800 r/min. The dehydration is performed by the centrifugal force, whereby the detergent component remaining in the clothes is separated from the clothes together with the washing water. It is judged whether the predetermined time has elapsed after the start of the rotation of the washing and dewatering tank 1 〇4 in step S205. When the predetermined time has not elapsed (No in step S205) 'returns to step S205. When the predetermined time has elapsed (Yes in step S205), the motor 109 is turned off (step S206). The rotation of the dewatering tank 104 is gradually lowered. The clutch switching device inside the drive mechanism portion 111 is switched, and the dehydration shaft 1〇5 is braked (step S207), and the washing and dewatering tank 1 〇4 is temporarily stopped. Then, the drive mechanism portion 111 is switched again. The internal clutch switching device 'releases the brake of the dehydration shaft 105 (step S 2 0 8 ). Thereby, the dehydration shaft 1 〇 5 'the laundry and the dewatering tank 〇 4 becomes a rotatable state. Then the motor is repeated again. The start of 109 (step S2〇9) and the closing of the motor 1〇9 (step S 2 1 0 ). With such a motor! 开9 opening and closing, the number of rotations of the washing and dewatering tank 104 is predetermined The time is maintained at a low-speed rotation of an average of 30 to 5 〇r/min. At the same time, the water supply valve 丨 17 is opened (step S21 1 ), and tap water is supplied to the washing and dewatering tank ι 4 in a spray form. The water is uniformly injected into the inner garment -8 - 201100601 which is adhered to the laundry and dewatering tank 〖4. The water-immersed clothing type 'dilutes or detaches the detergent component remaining in the clothes. In step S 2 1 2 , determining the water supply of step S 2 1 1 When the predetermined time has elapsed (step No. S212), the process returns to step S209 and step S21 1. When the predetermined time has elapsed (Yes in step S212), the process proceeds to step S213. Step S214 and step S 2 1 5. That is, the water supply valve 1 1 7 is closed (step S 2 1 3 ), the drain valve 1 0 8 is closed (step S 2 1 4 ), and the clutch inside the drive mechanism unit 1 1 1 is switched. The switching device thereby brakes the dewatering shaft 1 (step S2 15). Then, the washing and dewatering tank 104 is stopped to end the washing step (step S216). 0 When the washing step is finished, the second step is shifted to the dehydrating step. In the dehydration step, the washing and dewatering tank 104 is rotated at a high speed of about 700 to 800 rpm. By this high-speed centrifugal dehydration, the water contained in the clothes is dehydrated. Thereby, a series of steps of the washing machine is ended. In the conventional washing machine described above, for example, in the case of a washing machine having a washing capacity of 8 kg, the amount of water in the water level A in the washing step is about 5 〇 to 70 liter. In addition, the amount of water in the washing step is about 15 to 25 L. That is, in the washing step, about 1 to 25 minutes of water which is less than the laundry step is sprayed into the clothes. Thus, in the conventional washing machine, the washing performance can be obtained with as little water as possible. However, in the above-described conventional configuration, the water supply of the tap water to the clothes in the washing step is performed by opening and closing the water supply valve 1 17 for a predetermined time. That is, when the water pressure of the tap water is low, the amount of water to be injected is reduced. In this case -9 - 201100601, it is not possible to supply sufficient water to the clothing. If the water does not fully penetrate into the clothing, a washing distribution will occur. That is, the case where the water pressure is low is not sufficient. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a washing machine having a small amount of water efficiently and stably.

[Embodiment 1] Fig. 1 is a side sectional view showing a washing machine in accordance with a first embodiment of the present invention. Fig. 2 is a flow chart showing the washing step of the washing machine in the first embodiment of the present invention. Fig. 3 is a flow chart showing a washing step of the washing machine in accordance with the first embodiment of the present invention. In Fig. 1, the casing 1 has a groove 20 which is elastically suspended by a plurality of suspensions 2 therein. Thereby, the vibration at the time of dehydration of the outer tub 20 is absorbed by the suspension 2. Inside the outer tub 20, a washing and dewatering tank 18 for storing laundry is disposed. The washing and dewatering tank 18 is rotatably disposed around the washing shaft 5a which is hollow and double-reconstructed. At the inner bottom portion of the washing and dewatering tank 18, the pulsator 6 for agitating the laundry or the like is rotatably disposed. Further, at the bottom of the outer tank 20, there are provided a drain port 7 and a drain valve 8. A plurality of drainage holes 18 8 a are provided in the inner peripheral wall of the laundry and dewatering tank 18. The motor 9 attached to the bottom of the outer tub 20 transmits the rotation to the drive mechanism portion 1 via the belt 10. The drive mechanism unit 1 1 has a clutch mechanism, a brake mechanism, and a clutch switching device (all not shown). The drive mechanism unit 1 1 performs braking and brake release of the dewatering shaft 5. The drive mechanism unit 1 1 brakes the dehydration shaft 5 when the washing is performed, and drives the washing shaft 5 a to rotationally drive the pulsator 6 for the clothes. Further, when dehydration is performed, the drive mechanism portion 1 1 releases the brake of the dewatering shaft 5, and opens the drain valves 8 -11 - 201100601 ' to rotationally drive the washing and dewatering tank 18. The washing water or the washing water in the outer tub 20 is discharged from the drain port 7 at the bottom of the outer tub 2 through the drain valve 8' to the outside of the washing machine. A plurality of blades 19 having a fin shape in the outer peripheral bottom portion of the washing and dewatering tank 18 are formed in a radiating shape. Further, the frame cover 14 covers the upper portion of the frame 1. The frame cover 14 has an opening and closing cover 15, a water supply valve 17, and a control device 25. The opening and closing cover 5 is provided so that the frame cover 14 can be opened and closed freely. The water supply valve i 7 is connected to the water dragon of the tap water, etc. The tap water is supplied to the washing and dewatering tank 18. The control device 25 has an operation display unit (not shown). Further, the control device 25 has a microcomputer (not shown) or the like for controlling the motor 9, the clutch switching device, the water supply valve 17, and the drain valve 8. And the control unit 25 successively controls a series of steps of washing, washing, and dehydrating. The water level detecting device 24 detects the water level in the washing and dewatering tank 18. The water level detecting device 24 communicates with the lower portion of the outer tub 20 and is constituted by a pressure sensor or the like. The water level detecting device 24 converts the water pressure from the outer tank 20 into an electric signal. The water level in the washing and dewatering tank 18 is detected by comparison with the water level setting 预先 previously set in the control unit 25. The water level detecting means 24 detects the water level in the case of supplying water to a predetermined water level A in the washing step. Further, in the washing step, the water level of the predetermined water level B which is lower than the water level A is detected. An inner wall 2 1 is formed between the outer tank 2 〇 and the washing and dewatering tank 1 8 . The space between the inner wall 21 and the side wall of the outer tub 20 becomes a water-permeable tubular water supply portion 23. At the bottom of the inner wall 21, that is, the lower portion of the water supply portion 23, the lower inlet 22 is provided at -12-201100601. Here, by the rotation of the washing and dewatering tank 18, a plurality of blades 19 function as a pump, so that water flows in from the lower inflow port 22, and water is supplied upward through the water supply portion 23. In the upper portion of the outer tub 20, a donut-shaped flat upper cover 26 having a garment-input opening 30 formed therein is provided. The upper cover 26 is fixed to the outer tub 20, for example. A portion of the upper cover 26 is provided with a water injection portion 27 in which a plurality of holes are formed. The water injection portion 27 is a water passage which is a water when water is injected into the washing and dewatering tank 18 from the water supply valve 17. Further, a discharge port 29 is provided above the washing and dewatering tank 18. The discharge port 29 is located near the end of the opening 30 of the upper cover 26, and the water is discharged downward from the washing and dewatering tank 18. Further, the outer tank 20 and the upper end 28 are formed so as not to leak water and communicate with the discharge port 29 at a position corresponding to the upper end of the water supply portion 23 formed by the side wall and the inner wall 21. Thereby, the water supplied from the water supply valve 17 passes through the injection water portion 27 of the upper cover 26, and the discharge port 29 is sprinkled with water in the washing and dewatering tank 18. Further, the water that has flowed in from the lower inflow port 22 passes through the water supply unit 23 and the upper inflow port 28, and is sprinkled from the discharge port 29 into the washing and dewatering tank 18. Therefore, when the water is stored to the low water level shown by the water level B in Fig. 1, when the washing and dewatering tank 18 is rotated, the water is stirred by the pumping action of the vanes 19, and the water is sent from the lower inflow port 22. The water supply unit 23 passes through the upper inflow port 28, and then sprinkles water from the discharge port 29 into the washing and dewatering tank 18. The water sprinkled with water flows to the lower side of the washing and dewatering tank 18, and is again sent by the pumping action of the vanes 19. Thereby, water is sprinkled as a circulating water stream. Further, in the water level B of Fig. 1, for example, a part of the pulsator 6 is immersed in the water level. The operation of the washing machine of the above configuration will be described using the flowcharts of Figs. 5 and 6 . First, a description will be given regarding the washing step. When the washing step is started (step S400), the opening and closing cover 15 is opened, and the laundry of the laundry is put into the washing and dewatering tank 18 (step S4〇1). Then, the power switch is turned on (step S402), and when the start switch is turned on (step S403), the water supply valve 17 is opened (step S404). Here, the drain valve 8 is in a closed state. Thereby, the washing and dewatering tank 18 is supplied with water. The water level detecting device 24 detects the water level (step S 4 0 5 ). When the water level does not reach the predetermined water level a (No in step S4〇5), the process returns to step S4〇5 to continue the water supply. When the water level has reached the predetermined water level A (γ e s in step S 4 0 5 ), the water supply valve is closed (step S 4 0 6 ), and the water supply is stopped. Then, the motor 9 is turned on to rotate the pulsator 6 in the forward and reverse directions (step S4 〇 7). Thereby, washing is performed. In step S408, it is judged whether or not a predetermined time has elapsed after the pulsator 6 starts rotating. When the predetermined time has not elapsed (No of step S4〇8), the process returns to step S4〇8. When the predetermined time has elapsed (Yes in step S4〇8), the motor 9 is turned off (step S409), and the pulsator 6 is stopped. Thereby, the washing step is ended (step S410). When the washing step shown in Fig. 2 is finished, next, it is moved to the washing step shown in Fig. 3. When the washing step is started (step s 5 〇 〇 ), the drain valve 8 is struck (step S5 01). Then, the clutch switching device of the inner portion -14 - 201100601 of the drive mechanism portion is switched, and the brake of the dewatering shaft 5 is released (step S 5 02 ). Thereby, the washing and dewatering tank 18 is made rotatable via the dewatering shaft 5. At step S503, it is judged whether or not the drainage is finished. When the drainage is not completed (No in step S503), the process returns to step S503. When the draining has been completed (Yes in step S503), the motor 9 is started to be dehydrated as an intermediate dehydration, that is, in the washing step, and the washing and dewatering tank 18 is rotated (step Q S504). Specifically, the laundry and dewatering tank 18 is rotated at about 7 Torr to 8 OOr/min, so that the clothes are dehydrated by centrifugal force. Thereby, the detergent component remaining in the clothes is separated from the clothes together with the washing water. In step S505, it is judged whether or not a predetermined time has elapsed after the washing and dewatering tank 18 starts rotating. When the predetermined time has not elapsed (No in step S505), the process returns to step S5〇5. When the predetermined time has elapsed (Yes in step S505), the motor 9 is turned off (step S506). The rotation of the washing Q and the dewatering tank 18 is gradually lowered. The clutch switching device inside the drive mechanism portion η is switched, and the dewatering shaft 5 is braked (step S5 07) to temporarily stop the washing and dewatering tank 18. Then, the drain valve 8 is closed (step S5〇8). In other words, the water can be stored in the outer tank 20. Then, the clutch switching device inside the drive mechanism portion 11 is switched again, and the brake of the dewatering shaft 5 is released (step S509). Thereby, the washing and dewatering tank 18 is made rotatable via the dewatering shaft 5. Next, the water supply valve 17 is opened (step S510). Tap water or the like is supplied to the washing and dewatering tank 18. -15- 201100601 The water level detecting device 24 detects the water level (step 3511). When the water level does not reach the predetermined water level B at the low position near the outer circumference of the pulsator 6 (No in step S511), the flow returns to step S510 to continue the water supply. In the case where the water level has reached the predetermined water level B (Yes in step S51), the water supply valve is closed (step S5 1 2), and the water supply is stopped. Then, the motor 9 is turned on again to rotate the washing and dewatering tank 18 (step S 5 1 3 ). In this case, the rotation of the washing and dewatering tank 18 is a rotation number of about 180 to 200 r/min for a predetermined time. That is, in step S 5 14 , it is judged whether or not a predetermined time has elapsed after the washing and dewatering tank 18 starts rotating. When the predetermined time has not elapsed (No in step S5 1 4), the process returns to step S 5 14 . In this case, the washing water is stirred in the circumferential direction by the vane 19, flows in from the lower inflow port 22, passes through the water supply portion 23 and the upper inflow port 28, and is sprinkled from the discharge port 29 into the washing and dewatering tank 18 from above. Clothing category. Further, when the predetermined time has elapsed (Yes in step S514), the motor 9 is turned off (step S515). The washing water is soaked in the clothes and passed through the clothes by centrifugal force. At this time, the detergent component inside the clothes is separated from the clothes by the water of the clothes. The water passing through the clothes is discharged from the plurality of small holes 18 8 provided in the inner peripheral wall of the washing and dewatering tank 18 to the washing and dewatering tank 18, and is dropped to the bottom of the outer tank 20. The fallen water is again passed through the lower inflow port 2, the water supply portion 23, the upper inflow port 2, 8 from the spout port 2, and the water is sprinkled from the upper side into the washing and dewatering tank 18 by the pumping action of the vanes 19. Clothing in the middle. By repeating such forced circulation of water during the predetermined time period of step S 5 14 , the detergent components remaining in the entire clothing can be uniformly diluted. Further, the water circulated from -16- 〇 201100601 is continuously sprinkled from the top of the washing and dewatering tank 18, and visually gives an impression of good washing. After the predetermined time of step S 5 14 has elapsed, the motor is turned off (S515), and the drive mechanism 咅丨 clutch is switched by the clutch switching means. Then, the dewatering shaft 5 is braked (step S516), the dewatering tank 18 is stopped, and the washing step is terminated (step S517). When the washing step is finished, the second step is to the dehydration step. At this time, the washing and dewatering tank 18 is rotated in a row of about 700 to 800 rpm. By this high-speed centrifugal dehydration, dehydration is carried out in the clothes. Further, the dehydration here is the time of dehydration in the middle of the washing step. Thereby, a series of steps of the washing machine is ended. In the washing machine of the present embodiment, for example, when the washing capacity is 8 kg, the amount of water in the water level A in the washing step is approximately 50 - in addition, the amount of water in the washing step is displayed in the water level B near the outer periphery of the pulsator 6. About 1 5~2 5 L. That is, the water of Q 〜 2 5 L is temporarily stored, and the washing is circulated by the rotation of the washing and dewatering tank 18. Thereby, the water is sprinkled on the entire clothing body so that the water penetrates into the body, the detergent component inside the clothes is separated, and the scattering action is repeated again. Therefore, it is possible to increase the effect of diluting the detergent component of the entire garment with a small amount of water. That is, it is possible to ensure stable washing performance in a small amount. Further, in the case where the water is filled with the water supply valve of the conventional washing machine, the water is not washed by storing a small amount of water, and even if the water pressure of the water pipe is low, the washing unevenness can be prevented. That is, it will not be subjected to the water pressure of the water pipe, so in the 9 (step: 1 1 laundry and dehydration step, the speed of the water is longer and the laundry is 70L longer. The lower: about 15 water purification and strong clothing. The use of the water type control is the same as the case, and the low shadow -17-201100601 sounds to ensure stable washing performance. Moreover, the washing machine of the present embodiment has the portion 23 disposed behind the washing machine except as shown in FIG. In the right side of Fig. 1 'the water supply portion 23 a is also provided in front of the clothes dryer. In this case, the path of the washing water is two. That is, by increasing the amount of circulating water, one-liter washing performance can be obtained. As shown in Fig. 1, the upper cover 26 has an upper inlet 28a and a discharge port 29a at respective diagonal positions when viewed from the direction of the rotation axis of the upper inlet 28 and the discharge 29. Further, the inner circumferential surface of the outer groove 20 is partially Each of the inflow ports 28, 28a is provided with a lower inflow port 22, and water supply portions 23, 23a that connect the upper inflow ports 28, 28a and the lower inflows [22, 22a, respectively. Here, 2 One of the lower inflow ports 22, 22a of the portion is lower in FIG. The partial inlet 22) is provided in the bottom of the outer tank 20, and the other (the lower inlet 22a in Fig. 1) is a slightly central inner peripheral surface provided in the upper and lower directions of the outer f. Thereby, when the water level is low, the sprinkling water generated by the circulation from the lower inflow port 2 2 is watered, and the water from the lower inflow ports 22 and 22a is sprinkled. That is, different water can be sprinkled depending on the amount of water. Further, when the water level is low, that is, when the amount of water is small, when the water is sprinkled from the two outlets 29 and 29a, the amount of circulating water may be insufficient, and the washing performance may be lowered. In the present embodiment, in the case of water, only the circulation from the lower inflow port 22 is performed, and sufficient washing performance can be obtained even with a small amount of water. Because the water supply is in the washing cycle, the mouth is flowing on the upper 22a]22 side (the circumferential surface f 20, the upper part is produced by the higher level, but the amount is less water, this, -18- 201100601, when the water level is low, that is, the amount of water is small, When the water level is high, that is, when the water level is high, that is, when the amount of water is large, a large amount of water is sprinkled from the two portions, so that the water amount can be washed. Further, in the present embodiment, two sets of lower inlets are provided. The water supply unit and the discharge port are provided, but the same effect can be obtained by providing three or more lower inlets, water supply units, and discharge ports.
