DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described. In addition, the π of the present invention is not limited to the embodiment. 201037121 In the drum type washing machine of the first embodiment, as shown in Fig. 1, the inside of the washing machine body 2 is swayable. The water tank 3. The rotating drum 4 is provided with a freely rotatable rotating drum 4. The rotating drum 4 is a motor 5 mounted on the back side of the water tank 3 from the outside. The core 4c is rotated in the center. The fluid balancer 6 is disposed in front of the rotary drum 4 to reduce the vibration during the dehydration stroke. The fluid balancer 6 forms a rib 6a for preventing the credit card or the like from falling in front of the fluid balancer 6. The drum type washing machine of the present embodiment has an automatic control motor 5, a water supply system 7, a drain system 8, and a drying system 9 according to a mode setting or control program, as shown in FIG. 1, and at least performs a washing stroke, a water washing stroke, Dehydration stroke, dry dance stroke and other functions. If you can, the dehydration stroke and drying stroke can be omitted. Therefore, the drying system 9 can be omitted. The water supply system 7 is shown by the solid arrow A, and is not shown on the graph. The opening and closing of the water supply is performed obliquely, and the lotion of the lotion accommodating portion 7a is put into the water tank 3 in a timely manner. The drainage system 8 is opened and closed by the drain valve 19 as indicated by the chain arrow B. At the end of the washing stroke, when the water rinse is finished, etc., it is connected to the lower part of the water (four) water buckle, and after the drainage of the surface dust-reducing type, the water in the water tank 3 is drained. The drained milk is available from the outside. The following is performed by the blower 12 ... the deer d and the air in the rotary drum 4 as shown by the dotted arrow c in the figure. The drying system 9 has a trap line and is dusty ( Nuclear Lushe), the secret of the material is introduced into the dehumidification part of the air (not shown in the figure), and the air after heating and dehumidification becomes the drying height 7 201037121: the heating part of the dish and the working gas (not shown in the figure). The blower 12 will The high-temperature air is supplied to the rotating drum 4 through the wind-passing device 10. Further, in addition to the above, the drum type washing machine of the present embodiment is a water circulation system when necessary for the day of the washing and the flushing of the water. Charged with 3 liters of water in a 16-cycle water tank, and has the function of seeking the flushing of the water washing machine. The water is circulated through the water pump 3G, and the water in the water is drained through the drain pipe 8a. The drainage filter H 8 b, the flow side line 3 of the water circulation path 31, the flow side material 3la of the Wei 2Q, the (four) ring pump 20, and the discharge side route 31b of the circulation pump 20 of the water circulation route 31 are returned to the water tank 3. The mode of the operation stroke or the like or the selection of various functions is performed by inputting from the operation panel 21 provided on the front surface of the washing machine main body 2. The control °P22 is displayed on the display unit on the operation panel 21 based on the 4 input information to inform the user. In the meantime, when the start setting operation is started by the input setting unit λ疋 of the operation panel 21, the data is started from the water level detecting unit that detects the water level in the water tank 3. Thereby, the control unit 22 controls the operation of the drain valve, the water supply valve, and the like to perform the operations of washing, dehydrating, and dry material. The rotary drum 4 is coupled to the motor 5 directly connected to the water tank 3 on the rotating shaft. The rotary drum 4 and the water tank 3 are inclined from the opening side (the old left side) to the bottom side (the right side of Fig. 1), and the rotation axis direction is inclined from the horizontal direction to the angle 0 = 2 alumina 1 degree. By comparing with the case where the horizontal direction is set, although the rotary drum 4 is disposed at the same height, since the opening of the water tank 3 and the rotary drum 4 is obliquely upward, it is easy to take out and wash it without the need for a strong posture of bending down the waist. Things. In particular, from the experience of the inventors and the like, by setting the tilt angle to 201037121 2:, even if there is a gap from the child (except the child) to the height of the adult, even if the wheelchair is used, it can be easily taken out and released. Washing. In addition, the water is condensed and condensed, and the washing water in the bowl 4 is stored on the back side, and even a small amount of water can obtain a deep state of the water. The water tank 3 has the same inclination as the rotary drum 4 in order to increase the fear of washing the rotating drum, and is disposed along the vicinity of the rotary drum 4. Further, the washing machine body 2 is provided with a switch door 4〇. The opening and closing door 4 closes the opening U of the water tank 3 through the sealing member 14 attached to the edge of the bowl opening, and can also be opened. 〆,, ★ and 'Rotate the drum 4, the dehydration line is closed, then the south speed is continually rotated. Therefore, the smashing, twisting, and (4) of the washing material during the washing stroke and the water rinsing stroke are applied to the inner surface of the rotary drum 4 in the same state, and the printed matter is attached to the washing. Therefore, the washing is not easy to take out, and the handling afterwards is also very troublesome. Moreover, it is easy to leave wrinkles that are difficult to remove on the washing material, and it is quite troublesome to remove the enemy pleats. In order to eliminate such a thing, in the present embodiment, during the washing stroke, the washing process, and the water washing stroke, the rotating drum 4 has an alternating positive arc rotation of more than 90 degrees and less than 180 degrees. Rotating forward and reverse arc rotation drive mode. Furthermore, in the washing course, the washing course and the water washing process, there is a rotation speed in which the washing object k lifted by the rotation of the rotary drum 4 is better than the weight of the self-weight. Further, the forward-reverse continuous rotation driving mode of the continuously rotating rotary drum 4 is alternately repeated using the aforementioned rotational speed. Further, in the washing stroke, or the washing stroke and the flushing stroke, the forward and reverse arc rotation driving mode and the forward/reverse continuous rotation driving mode are alternately executed. Thereby, the entanglement and distortion of the washings can greatly improve the improvement of the mechanical strength, and it is also not easy to produce wrinkles. That is, in the present embodiment, the rotary drum 4 is rotated more than 9 degrees and less than 180 degrees, and the arc is rotated and slammed, and the washing can be lifted up to more than 90 degrees 'less than 180 degrees. After that, the washings are stopped by the washings when they are lifted to the final stage, and the washing state is stopped. The washings will be peeled off from the inner surface of the rotating drum 4 according to their inertia and self-weight, and the laundry will be lifted and lifted by its own weight. The opposite side of the left and right falls. Therefore, for a washing material which is very swellable in water and soft and slippery, it is especially used for high unwinding, and the mechanical force can be τ - , , , -x/ 才 ·, j 土Η£Γ Ο The positive and negative arc rotation driving mode by the alternating positive arc rotation of the positive direction of the arc rotation drive and the reverse reverse direction of the reverse direction of the fox rotation is driven by the sharp arc rotation of the positive and negative fathers, and the high position of the washing object The drop position is alternately interchanged left and right each time the arc is driven. Therefore, not only is the entanglement of the washing material prevented, but also the effect of unwinding is enhanced, and the mechanical force is increased to affect the washing seam. Therefore, the washing performance can be improved. Unlocking the fairy can be (4) tangled between the washing and the clear water.

However:: the washing of the part, easy to produce, can be replaced (4) above ^ ^ continuous rotation drive mode Reverse continuous rotation drive mode of the combination: the position. That is, by not only the entanglement, distortion, and _ of the washings in the type of the positive and negative arcs 10 201037121 can be alleviated, and the mechanical force that is unbalanced in the positive and negative, the middle, the middle, and the washing can be alleviated. Therefore, by means of the two modes, two different actions can be assigned in the rinsing, arranging, winging, ♦, and sputum flushing.

However, the washing machine of the drying stroke is easily attached to the inner surface of the rotary drum 4, so that the rotation angle of the rotary drum 4 is preferably set at 9 inches. Above, less than 2〇〇. . The maximum rotation speed of the rotary drum 4 in the forward-reverse continuous rotation drive mode is set at 45 ± 5 rpm. Rotation of the positive and negative arc rotation drive mode The maximum rotation speed of the drum 4 is set to 40 rpm or more during the washing and rinsing strokes, and is preferably set to 5 〇 rprn or more after dehydration. Here, the circulation pump 20 will be described. The circulation pump 20 is fixed to the platen 2a at the bottom of the washing machine body 2 as shown in Fig. 1. Specifically, the circulation pump 20 is formed as shown in Figs. 2A to 2C, and the opening side of the resin pump casing 20b accommodating the impeller 20a is formed by the bearing partition 20dl at the front end of the metal motor casing 20d of the circulation motor 2〇c. Integration. The impeller 2〇a is directly coupled to the motor shaft 20e'. The impeller 20a is embedded in the resin mount 35. Three places around the mount 35 have a slightly C-shaped mounting piece 35a. These mounting pieces 35a are screwed into the platen by bolts (not shown) 11 201037121. The upper convex portion (not shown) is attached to the platen 2a±. The circulation system 2 吸水 absorbs water through an L-shaped suction port integrally formed at the lower portion of the pump casing 20b. Thereafter, the discharge port 2〇g is integrally formed in the wiring direction of the chestnut casing 20b, and the washing water is discharged from the peripheral wall of the water tank 3 via the discharge side path 31b. Next, the water circulation system 16 is shown. The water circulation system 16 causes the washing water in the water tank 3 to circulate in the rotary drum 4 by being connected to the money water circulation route 31 by the circulation pump 2G provided in the water circulation path 31. First, as shown in Fig. 1 and Figs. 3A to 3C, the discharge line Mb' of the lowermost portion of the front end wall 3h around the opening 13 of the water tank 3 is connected to the ejection port from the outside. 5, as indicated by the solid arrows D1 and D2 in the figure, the inside of the front end wall of the water tank 3 and the surface of the front end wall 4b of the rotating drum 4 opposite thereto are from the spit secret line. The swill water (the rinsing water supplied to the water tank 3 is circulated through the water circulation route 3, hereinafter referred to as circulating water). Thereby, water is discharged into the rotary drum 4 through the flow path 5 2 formed between the front end wall 3 h of the water tank 3 and the surface of the front end wall 4b of the rotary drum 4. At this time, the motor rotation speed of the circulation pump 2 is set to, for example, 3,500 rpm. The injection port 51 from the water of the exit side line 31b can prevent the washing material from being caught by the ejection opening 51 due to the position where it is not in contact with the washing material in the rotary drum 4, and disturbs washing or water washing, drying, etc. Necessary actions, or scratching or breaking the washings. Also, it won't damage the look of good looks. Further, the 'flow path 52 is formed between the front end wall of the water tank 3 and the i% wall 4b before the rotary drum 4'. It is not necessary to use special parts, and it is generally configured by using a sealing member 56 (see FIG. 3C) which will be described later. It can easily and inexpensively reduce the risk of leakage 12 201037121 water. The injection port 51 is located inside the front end wall 3h of the water tank 3, and is opened in the direction of the center of rotation of the rotary drum 4 as shown in Fig. 3C. Specifically, the injection port 51 is formed between the front end wall 3h of the water tank 3 and the front end wall 4b of the rotary drum 4, and opens toward the annular outlet 53 of a portion of the flow path 52. Therefore, the circulating water sprayed from the injection port 51 is efficiently discharged from the flow path 52 to the center of rotation of the rotary drum 4 as indicated by the solid arrow D. Specifically, the circulating water is efficiently discharged toward the inner side of the rotary drum 4 in the radial direction toward the annular outlet 53. Therefore, the washing water can be efficiently supplied regardless of the amount of the laundry. In particular, the front end wall 3h of the water tank 3 has an inclined surface 3hl and a curved surface 3h2. The inclined surface 3hl is inclined toward the inner side from the position opposite to the ejection opening 51, and is inclined toward the rear side of the washing machine body 2; the curved face 2 is bent from the inclined surface 3hl to the inner circumference and toward the opening 54 side of the rotary drum 4. . As a result, the circulating water sprayed toward the flow path 52 is discharged from the inclined surface 3h 1 toward the curved surface 3h2 as indicated by an arrow (see) in Fig. 3C, and is discharged to the inside of the rotary drum 4 through the opening 54 of the rotary drum 4. Therefore, the efficiency of supplying the circulating water to the laundry can be improved. Here, a connection port 51a connecting the discharge side path is formed at the front end wall of the water tank 3. The circulating water is sprayed from the connection port 51a to the injection port 51 of the flow path brother, to the flow path 52, toward the rotation center side of the rotary drum 4, and the opening σ is formed in a predetermined range in the circumferential direction. In this way, in order to provide the connection port ... in the front end wall 3h of the water tank 3, the injection water is formed by the discharge side path 31b, and the circulating water is correctly guided to the flow path = side through the injection port 51 from the discharge side path 31b. Therefore, the water is accompanied by a predetermined range W2 from the annular outlet 53 corresponding to the circumferential direction of the spray: (4), and is spread toward the left and right sides 13 201037121 (left and right from the front of the washing machine body 2) in the predetermined direction, and is stabilized. The ground is discharged into the rotary drum 4. The , , , , and σ fruits can be accurately guided to the flow path 52 through the injection port W from the connection port 51a. By this, the discharge of the circulating water from the predetermined range corresponding to the circumferential direction of the injection port 51 to the right and left direction is stabilized, and the water supply can be stably and efficiently irrespective of the number of the washings of the rotating drum. Further, the "injection port 51 guides the opening of the circulating water to the flow path" between the outlet side of the discharge side and the connection end #55d connected to the connection port 51a. Thereby, it is provided in the discharge side path 31b. The connection port 51 is a venting port Μ, which is a side of the circulatory water surface 52, and the squirrel is connected to the π 51& The shape can meet the appropriate guiding conditions. That is, for the side of the sales road 52, by the above simple shape: the shape, the direction of the right wind can be more sufficient to discharge the water in the direction of the circle. : Discharge of water flow width, forward and backward flow rate, etc., regardless of the washing matter; less spit and 'the piping structure is not particularly complicated by $, and the conditions are introduced. It will not become a cost increase, and there is no risk of water leakage. , and the mountain 'As shown in Figure 3A to 3C, the injection port (4) is open to the water sample: the road: the approximate center position of the wide bottom, and the mouth opening 51 invites the spit: = the tube 55 is the two front and rear members 5 together; flat; spit out side route and relative to jet port 51 The opening position is 14 201037121 Ο

Further, the tube 55 is connected by a connecting pipe 55c integrally formed at one end of the rear member 55b, and is connected as an extension portion thereof on the discharge side path 31b. Further, after the tube 55 extends approximately horizontally from the one end side to the lower side of the ejection opening 51, the end side thereof is bent and raised to the ejection opening 5, and as shown in Fig. 3C, the connection of the rising portion of the rear member 55b is shown. The part 5 brother is integrally formed at the connection end portion 55£1, and the member 55 is connected to the connection port 51a of the front end wall 3h of the water tank 3 of the injection port 51, and is sealed by a sealing member 56, and both It is fixed by screws 57. In this way, the connection portion that is connected to the connection port 5ia from the front end wall of the water tank 3 is said to protrude to the outer periphery of the water tank 3, and is connected to the tube 55 on the 2G side of the county to form a flat shape, and the front end of the water tank 3 is Wei Qian. The small space between the front wall of the clothes machine body 2 can also be piped. Further, since the flat shape of the tube 55 can rectify the circulating water to the width of the water flow of the opening of the proportional injection port 51, the thickness of the water muscle is directed from the connection port 51a toward the injection port η, and is sprayed toward the flow path, thereby proceeding from the throat outlet 53 % water is sprinkled in a large circumferential direction, sufficient in the front-rear direction, and the thickness of the soil, or the spouting speed range in which the splash distance can be increased, so that the water flow can be provided in an undisturbed manner to provide circulating water, thereby improving washing and water. The effect of rinsing. The vertical S 55 extends from the outer circumference of the water tank 3 to the lower side of the connection of the spurting α51 close to the front end wall 3, and from there to the connection port, the connection port 55d is connected by the connecting end 55d of the curved rising portion. 51a.

In addition, in order to guide the circulation from the injection σ51 provided in the connection a51a to the side of the path 52, the shape of the portion 55e is formed by the simple connection of the toe portion 55e with the discharge side path 31b. The discharge water flow width in the circumferential direction of the circle 1 and the sufficient discharge flow rate in the forward and backward directions, or the discharge flow rate which can increase the distance between the linings, etc., regardless of the washing matter (how much, the effect condition can be full) Guidance, heart, piping construction; 16 201037121 is not particularly complicated, does not increase the risk of water leakage, and does not become a cause of cost increase. Here, as shown in Fig. 4A, the front end wall 4b of the rotary drum 4, The front end wall 4b has a front end wall diameter portion 4b1 and a front end wall diameter small portion 4b2. Therefore, when the rotary drum 4 rotates, the injection port 51 is opened. Corresponding position, that is, at the lowermost portion, the front end wall 4b of the rotary drum 4, as shown in Fig. 4B, the front end wall diameter portion 4b1 is located in the up and down direction and can be moved to the lower side, as shown in Fig. 4C. The front end wall small portion 4b2 is located above and below The front end wall 4b is located on the curved surface of the front end wall 3h of the water tank 3 when the front end wall 4b is moved to the lower side at the corresponding position of the injection port 51. Therefore, when the circulating water is discharged from the annular outlet 53, it is suppressed by the curved surface 3h2, and as indicated by the solid arrow D1, the circulating water is discharged toward the lower side of the rotary drum 4. Further, the front end small diameter portion 4b2 is located. In the up-and-down direction, that is, when the front end wall 4b is moved upward at the corresponding position of the injection port 51, the front end wall 4b is located higher than the curved surface 3h2 of the front end wall 3h of the water tank 3. Therefore, the circulating water is discharged from the annular outlet 53. When the discharge is pushed up by the front end wall 4b, as shown by the solid arrow D2, the circulating water is discharged toward the top of the rotary drum 4. Therefore, the corresponding position of the injection port 51, that is, at the lowermost portion, and the front end wall 4b at the lowest point. That is, when the front end wall diameter portion 4b1 is positioned in the vertical direction, the circulating water is initially discharged toward the lower side of the rotary drum 4. The rotation of the front end wall 4b is gradually increased, and the discharge direction of the circulating water is also increased. Will change to the top, When the rotation is 90 from the starting point, the front end wall diameter small portion 4b2 is located in the up and down direction 'and the front end wall 4b reaches the top dead center, and the circulating water becomes the rotation of the rotating drum 4, 201037121, and the front end wall 4b is slowly lowered, and the spout is discharged. The direction will also slowly change upwards, :: the side reaches the bottom dead center, the circulating water becomes sprinkled below the rotating drum 4, always from the bottom to the ancient movement, the circulating water spits out the money..., the top to the bottom changes In the rotating drum 4, the circulating water is widely distributed in the rotating drum 4, and the effective yang can be supplied to the right object. As a result, the dissolution effect of the washing agent, the washing effect, and the flushing effect of the water can be used. Or when washing and reducing the weight of the A piece of clothing, the circulation of the water to the part of the above-mentioned clothes can reduce the unevenness of the washing performance of the b, and / month water washing performance. Further, as another example of the front end wall flap of the rotary drum 4, the front end (four) surface of the rotary drum 4 can be formed into a slightly polygonal shape (including a polygonal shape) in front. Thereby, the rotation direction of the front end wall surface, that is, the front end wall portion 3 is close to the annular outlet 53 of the circulating water, and the discharge direction is downward. The direction of the center of the polygonal side, that is, the front end wall small portion 4b4 is close to the circulating outlet 53, and the discharge direction is upward. In this way, the cycle is bred on the wash. Further, when the rotary drum 4 is rotated once, the circulating water is discharged while being up and down depending on the number of vertices of the polygon. Therefore, the more the number of vertices of the polygon is, the more the cylinder rotates, and the direction of discharge is changed. As in the above embodiment, the surface of the front end wall 4b of the rotary drum is formed in an elliptical shape or a polygonal shape as viewed from the front of the rotary drum 4. However, if the shape is not a line-symmetric shape such as an ellipse or a polygon, it is only necessary to change the distance from the rotation axis to a shape that is less than two kinds of shapes by rotating the rotation of the roller 18 201037121. Further, in the present embodiment, the circulation pump 20 is disposed on the platen of the bottom of the washing machine 2, but the present invention is not limited to this embodiment. In order to circulate the washing water in the water tank 3, the circulation pump 20 is disposed in the lower portion 3b of the water tank 3 (see Fig. 1), and the same effect as that of the present embodiment can be obtained.

Specially formed in the sink and the general shape (four), the seal needs a connecting pipe. Because of the special flow of the road between the castles; 19 201037121 Therefore, the risk of water leakage is also small, The circulating water is discharged into the rotating drum by a simple and inexpensive piping structure. Further, even if the circulating outlet of the circulating water has no special shape or structure, the surface of the end wall of the rotating drum changes due to the distance from the rotating shaft center, and the rotating drum utilizes Rotation, the direction in which the circulating water is discharged is changed up and down. Therefore, it is not necessary to use a complicated structure, and the circulating water can be uniformly sprayed on the washing matter regardless of the amount or type of the washing in the water tank. Further, in the present invention, the surface of the end wall of the rotating drum exhibits an elliptical shape from the front of the rotating drum. By this configuration, the rotating drum rotates the elliptical surface of the front end wall surface. When the long axis direction is close to the discharge port of the circulating water, the discharge direction is downward. The short axis direction of the ellipse is close to the circulating water. In the outlet portion, the discharge direction is upward. Thereby, the circulating water can be uniformly sprayed on the washing object. Further, since the cylinder rotates once for each of the two major axis directions and the short axis direction, the circulating water is twice. Further, in the present invention, the front end wall surface of the rotary drum exhibits a polygonal shape as viewed from the front of the rotary drum. With this configuration, the apex of the polygonal front end wall surface of the rotary drum is close to the circulating water. In the discharge port, the discharge direction faces downward. When the center direction of the side of the polygon approaches the discharge port of the circulating water, the discharge direction faces upward. Thereby, the circulating water can be uniformly sprayed on the washing object. At one time, the circulating water will change up and down depending on the number of vertices of the polygon. Therefore, the more the number of vertices of the polygon, the more the cylinder will rotate and the direction of the discharge will be densely changed.
