Hereinafter, the washing machine disclosed in Patent Document 1 will be described using Fig. 4 . Fig. 4 is a side cross-sectional view showing the overall configuration of a conventional washing machine described in Patent Document 1. As shown in Fig. 4, the conventional washing machine is provided with a water tank 3 disposed in the outer tub 2, a circulating water passage 120 disposed in the vertical direction on the inner circumferential surface of the water tank 3, and a bypass water passage 12 provided at the upper end of the circulating water passage 12 The lint filter 15 is composed of a spouting opening 140. On the inner surface of the bottom of the water tank 3, there is provided a rotary wing 5 which is formed by the rear wing 5〇2 being radially opposed to the bottom of the water tank 3. On the other hand, when the rotary vane 5 is rotated while the water tank 3 is accumulating water, the water at the bottom of the water tank 3 is pumped by the tail fin 502, and is sent to the lower end opening 130 of the circulating water passage 120 by twisting through the water outlet. . Thereafter, the incoming water rises in the circulating water passage 120 and is discharged into the water tank 3 through the spouting opening 140. At this time, foreign matter such as lint mixed with water discharged into the water tank 3 is collected by the lint 201209242 filter 150. Further, since the conventional washing machine automatically selects the amount of water according to the amount of the laundry, the amount of water in the water tank 3 is set to a lower position when the amount of H secret is small. At this time, the pumping action of the tail 5 () 2 of the rotary wing 5 is weak, and the water cannot sufficiently raise the water to the spouting opening 130 at the upper end of the rich road 12Q. Therefore, the amount of water is reduced by the lint; the trapping efficiency of the foreign matter is lowered. Therefore, a method of setting the water level of the cotton thief filter 150 to increase the efficiency of the foreign matter by increasing the water level of the thief filter 150 is considered. However, in such a case, even if the amount of laundry is small, it is always necessary to set the amount of washing water or more, so that the effect of saving water cannot be achieved. [In the Japanese and Japanese versions, the invention discloses that the washing machine of the present invention includes a water tank having a rotating wing at the bottom and a groove that can be freely rotated inside the water tank, and the washing machine is provided with a first circulation water path on the inner circumferential surface of the water tank and In the second (fourth) water passage, the material circulation water passage includes a first opening portion provided at a position facing the outer peripheral side of the rotary wing, and has a first opening portion. Further, in the i-th transition portion of the i-th discharge portion above the weir, the second circulation water passage includes a second opening portion that is disposed at a position facing the outer peripheral side of the rotary wing, and a second discharge portion that is located in the water tank. And a second transition device having a third discharge portion provided between the second opening and the second discharge portion, and the second discharge portion is disposed at a position lower than the first discharge portion. Thereby, even if the water level is set to a low water level, the water can be shouted (four) by the second circulating water path. As a result, the collection efficiency of foreign materials such as cotton velvet can be improved. 201209242 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a side cross-sectional view showing the entire structure of a washing machine in accordance with an embodiment of the present invention.

Fig. 4 is a side sectional view showing the entire configuration of a conventional washing machine. C. The cold type j is used to implement the best mode of the invention. Hereinafter, the embodiment of the present invention will be described with reference to the drawings. Further, the present invention is not limited to the embodiment. (Embodiment) FIG. 1 is a side cross-sectional view showing the entire structure of a washing machine in accordance with an embodiment of the present invention. As shown in Fig. 1, the washing machine of the present embodiment includes a water tank 3 having a plurality of water-passing holes 16 in the periphery thereof, and a groove 2 which is rotatably wrapped in the water tank 3. The outer tub 2 prevents the vibration of the outer tub 2 from being transmitted to the outer casing 1 by being supported by a plurality of hangers (not shown) inside the outer casing. The upper end portion of the water tank 3 is provided with a balancer 11 for suppressing vibration when dehydrating from the center. The bottom of the water tank 3 is provided with a rotary wing 5, and the rotary wing 5 is freely rotatable. The rotary wing 5 includes a feed wing 5〇1 formed on the opening side of the water tank 3 and a radial tail 502 provided on the bottom side of the water tank 3. Further, the rotational power of the motor 6 attached to the lower side of the outer tub 2 is transmitted to the water tub 3 and the rotary vane 5 via the motor pulley 7, the belt 8, the main pulley 9, and the 201209242. The power switching unit _ logically switches the connection between the water tank 3 and the transmission shaft of the rotary wing 5 so that the water tank 3 and the rotary wing 5 rotate in a body when the water is dehydrated, and only the rotary wing 5 rotates when the air is rotated. . Further, the structure of the water tank 3 and the rotary vane 5 may be rotationally driven without being transmitted through the belt 8 or the like. A second water passage wall member 3A is attached to the inner circumferential surface of the water tank 3. A first circulating water passage 12 extending in a direction perpendicular to the vertical direction t and having a flat cross section is formed between the i-th member 3G and the inner peripheral surface of the water tank 3, and the first water passage 12 is included in the lower end opening. The mouth and the second filter 15 having the first discharge portion of the upper sweat port. In the third vomiting section, u can be used to capture cotton velvet filters such as cotton velvet. Moreover, the second water passage wall member 31 is attached to the inner circumferential surface of the water tank 3. Further, between the wall member 31 and the inner peripheral surface of the water tank 3, a second circulating water passage extending substantially in a vertical direction (匕3 perpendicular direction) and having a flat cross section is formed, and the second circulating water passage 17 is included in the second opening of the lower end opening. The portion 18, the end door 〇々, the second discharge portion 19 of the cymbal, and the second filter 25 that is provided below the second discharge portion 19 and protrudes in the inner direction of the water tank 3. The second filter 25 is provided with a third discharge portion, and the second discharge portion 19 of the second circulation water passage 17 is provided at a position lower than the first discharge portion 14 of the second circulation water passage 12. Thereby, when the washing water level is set to the low water level, the second discharge portion 19 can sufficiently discharge the water even if the water pressure is low. Gentleman and 'Q Wo' can capture the efficiency to capture foreign matter such as cotton velvet, and fully dissolve the laundry detergent into the short-time, and can set the running time of the rotor Washing with high cleaning performance. Hereinafter, the second circulation water passage 17 will be described in detail using a map. 201209242 Fig. 2 is a perspective view showing the internal structure of the second construction path of the road of the present invention. Further, Fig. 2 is a perspective view showing the inner side of the second circulating water route of the washing machine of the embodiment of the present invention (the front side of the second circulating water path). Fig. 3 is a perspective view showing the second circulating water of the washing machine of the embodiment of the present invention as seen from the outer peripheral side of the water tank (the back side of the second circulating water passage). As shown in Fig. 2 and Fig. 3, the second circulation water passage is composed of a second opening 18 having a lower end opening, a second discharge portion 19 opening in the inner side of the water tank 3, and a main member 2G formed. And the inner opening of the filter is substantially box-shaped (including box type) and a squirrel is formed: the tamper 25 is disassembled. Further, as shown in Fig. 3, the water passage 22a and the water passage 22b which are connected to the second discharge portion 19 by the second opening portion ι8 are provided on both sides of the filter chamber 21 inside the second circulation water passage 丨7. Further, the water passage 22a and the water passage 22b side of the filter chamber 21 are provided with individual water outlets 23a and 23b above the lint filter 33 of the second filter 25 which is detachable. The second filter 25 includes a filter film 40 and a mesh lint filter 33 for collecting lint or the like. At this time, the lint filter 33 having a substantially bag shape (including a bag shape) is provided in the second filter 25 so as to protrude in the inner direction of the water tank 3. By the way, when the reverse rotation or stop of the rotary blade 5 during the washing or washing operation or when the washing water flows from the inside of the water tank 3 to the second circulating water passage 17 during the draining operation, the cotton of the second filter 25 is used. The cashmere capture surface is relatively resistant to the flow of water, and it is difficult to face the lint filter 33 to reduce the flow rate of water. As a result, since the defect of the lint recovered by the 201209242 lint filter 33 can be prevented from returning to the sink 3, the level of the washing water level is irrelevant, and the lint attached to the clothes can be greatly reduced at the end of the washing. The water that has flowed in and out of the filter 25 flows through the water outlet 23a and the water outlet 23b of the filter chamber 21 of the second circulating water passage 17 provided above the lint filter 33 of the second filter 25. Thereby, the foreign matter can be efficiently collected, and the lint of the trapped lint filter 33 can be easily released when the washing operation is stopped such as the reversal of the rotary wing. Further, since the second filter 25 is provided to protrude into the water tank 3, the clogging of the lint filter 33 or the like can be easily confirmed, so that the filter can be appropriately cleaned. In this case, the lint filter 33 may be formed by, for example, a fiber of a polyester resin fiber to which an antibacterial treatment has been applied. This prevents the generation of fungi such as cotton lint that has been captured, and washes them in a hygienic manner. Further, the second filter 25 is configured such that the filter membrane 4 can be detachably attached to the filter chamber 21 of the main member 20 of the second circulating water passage 17. Further, the filter film 40 includes a protruding portion 42 formed at the lower end and a fitting portion (not shown) of the filter chamber 21 having a substantially U-shaped upper end (including a U-shape) and the fitting claw portion 432. Holding portion 41. At this time, by forming the holding portion 41 by, for example, a resin, the holding portion 41 can be elastically deformed, and the filter chamber 21 and the second transition piece 25 can be detachably attached. Specifically, when the filter membrane 4 is attached to the filter chamber 21, first, the projections (four) 42 formed at the end of the nipple are inserted into the pocket portion 44 of the continuation member 2 to 20. Then, the claws and the rotation of the portion 41 provided in the over 40 are pivoted to the locking hole 45 provided at the upper end portion of the filter chamber 21 through the 201209242. Thereby, the claw portion 43 of the holding portion 41 is fitted to the locking hole 45 provided at the upper end portion of the filter chamber 21, and the filter film 40 of the second filter 25 is supported by the claw portion 43 of the holding portion 41. The protruding portion 42 is fastened and housed in the filter chamber 21. On the other hand, when the filter membrane 40 is to be taken out from the filter chamber 2, the upper portion of the holding portion 41 is first pulled down while being pulled down. Thereby, the engagement between the claw portion 43 of the second filter 25 and the locking hole 45 of the filter chamber 21 is released, and the filter membrane 40 and the lint filter 33 are integrally separated from the filter chamber 21, and the second filtration can be easily performed. The lint filter 33 of the device 25 is cleaned. That is, the lint caught in the lint filter 33 generally contains a large amount of moisture such as dirt or detergent, and when placed in the poorly ventilated water tank 3, fungi may be generated in the lint filter 33. Therefore, by detaching the filter membrane 40 from the filter chamber 21, the second filter 25 can be easily cleaned, and a sanitary washing machine can be realized. Further, on both sides of the filter membrane 40, when the second filter 25 is attached to the filter chamber 21, a water passage 23a for allowing water to pass through the filter chamber 21 and a gap of the water outlet 23b to the second filter 25 are provided. Part 34. Further, a reservoir 32 is provided below the filter chamber 21. At this time, the water outlet 23a and the water outlet 23b of the filter chamber 21 are provided at a position higher than the lowermost end portion of the cotton filter 33 of the second filter 25. In other words, when the second filter 25 is fitted into the filter chamber 21, the water outlet (the water outlet 23a and the water outlet 23b) of the filter chamber 21 is disposed above the lower end of the second filter 25. . Further, water such as washing water which is configured to circulate flows into the water tank 3 through the lint filter 33 provided in the second discharge portion from above the second filter 25. 201209242 By this, when the reverse rotation operation of the rotary blade 5 is stopped or during the draining operation, the second discharge portion 流入9 can flow in and the upper circulation water passage 17 can be moved from the upper direction to the downward direction. The washing water in the counter-current water tank 3 flows into the lint filter 33 of the second filter 25 through the water-passing port 23a and the water-passing port 23b via the water passage 22a and the water passage 22b of the second circulating water passage 17, so that foreign matter can be collected. Further, as shown in Fig. 3, inside the second circulating water passage 17, the water passages 22a and the water passages 22b are provided with individual projections 24a and projections at positions opposite to the water outlets 23a' to 23b of the filter chamber 21. The portion 24b narrows the cross-sectional area of the flow path in the vicinity of the water inlet 23a and the water outlet 23b. Thereby, the discharge water pressure from the second discharge unit 19 can be secured, and the amount of water flowing into the second filter 25 through the water outlet 23a and the water outlet 23b of the second circulation water passage 17 can be secured. The operation of the washing machine of the present embodiment configured as above will be described below. First, when the rotary blade 5 is rotationally driven in a state where a predetermined amount of water is accumulated in the outer tank 2, the mixing blade 5〇1 shown in Fig. i is provided on the upper surface of the rotary blade 5 in the water tank 3. Shouting the flow of water that rotates in a generally horizontal direction (including the horizontal direction). At this time, the water between the bottom surface of the rotating groove 5 and the bottom surface of the outer groove 2 is sucked up by the water passing portion by the pumping action of the tail fin 5〇2 of the rotary wing 5. The water sucked up by the picker is respectively The first opening 13 passes through the first water passage 2 to the third discharge portion 14, and the first opening portion 13 is smoothly conveyed toward the second discharge portion 19 via the second circulation water passage 。. The rising water of the correction water passage 12 passes. The lint filter of the first filter 15 is ejected into the water tank 3. Further, the water rising from the second discharge portion i 9 f ^ # 3 P 17 is discharged into the under-groove 3. At this time, at the second One part of the circulating water passage 10 is discharged to the transition chamber 21 through the water outlet 23a and the water outlet 23b, and is ejected through the lint filter 33 provided in the third discharge portion 23 of the second filter 25 to The water tank 3. At this time, for example, when the amount of the washing material is higher than the water level of the washing water (for example, the water level H in Fig. 1), since the pressure of the rising water in the first circulating water passage 12 is high, the passage is high. (1) The discharge portion 14 is smoothly discharged into the water tank 3 by the first filter 15. On the other hand, when the amount of laundry is small, the washing water level is low (e.g., In the water level L) of Fig. 1, since the pressure of the water rising in the second circulation water passage 12 is low, the water discharged from the first filter 15 is reduced. However, the second circulation water passage 17 is provided in The second circulation water passage 12 is at a lower position, and the distance between the second shield circulation water passage 17 and the opening portion of the first circulation water passage 12 to the discharge portion is shorter, thereby even when the water level is low (for example, the second map) In the water level L), the water is likely to rise in the second circulation water path 17, and can be ejected into the water treatment tank 3 through the second transition unit 25 without being stagnant, thereby capturing the lint transition unit 33 of the second filter 25. The foreign matter such as cotton linters is collected. As described above, the washing machine of the present embodiment, the net of the non-washing water level is low, can be more effectively removed by the first transition device 15 and the second transition device 25 to remove the water in the water tank 3. In addition, because all the water level is set, it can be: the first water keeps the water pressure and the water discharges out, so the water _washing (four) detergent will fully ride in the short «, and can be set within the running time Washing with high washing performance. Further, in the main component 2 of the second circulating water passage 17, according to The thickness of the film 4 is formed to form a concave portion recessed toward the second circulating water path 17, and the transition film 4A may be attached to the main member 20. Thereby, since the second transitional region does not protrude toward the front 201209242, Therefore, for example, it is possible to prevent the laundry from being caught in the second filter 25 during washing.
