The water cap 30 is removed by the wire end filter 38, and water is sprinkled from the nozzle 34 into the washing and dewatering tank 9.

The details of the rotary wing disk 11 are shown in Figs. 3 to 7 . 3 is a perspective view of the rotary wing disk 11, and FIG. 4 is a top view of the rotary wing disk 11. (Fig. 5), Fig. 5 is a schematic plan view of the vicinity of the boundary between the ridge and the valley, and Fig. 6 is a cross-sectional view of the rotary wing 11 cut along the left and right center lines IV-IV of Fig. 4, and Fig. 7 A cross-sectional view of the rotary wing 11 cut by the center line VV of the upper and lower sides of Fig. 4 is shown.

The upper surface of the rotary wing disk 11 is composed of a plurality of ridge portions 11a and a valley portion 11b formed between the ridge portions 11a. In the present embodiment, the two raised portions 11a formed by sandwiching the rotation center P of the rotary wing 11 and the two valley portions 11b formed between the raised portions 11a are provided. In the present rotary disk 11, the first inclined surface 11g on which the raised portion 11a is formed and the second inclined surface 11h on which the valley portion 11b is formed are connected. Specifically, when the rotary wing disk 11 of the present embodiment is moved from the second inclined surface 11h to the first inclined surface 11g, the inclination angle is rapidly reduced. In this way, by providing the inclined sharpening portion on the upper surface of the rotary wing 11, the boundary portion between the second inclined surface 11h and the first inclined surface 11g is raised to form an expanded shape (see FIG. 5), and the portion is washed. The object exerts an upward force that promotes the alternating of washings that overlap each other.

As shown in FIG. 4, the first inclined surface 11g moves toward the outer diameter side from the inner diameter side close to the rotation center P, and the circumferential direction region gradually expands, and the circumferential direction region becomes the largest at the outer diameter end surface 11f. Further, the first inclined surface 11g includes a ridge line 11a1 that is relatively higher than the other regions, and the circumferential direction is continuously lowered to form a mountain-shaped convex curved surface. On the other hand, the second inclined surface 11h includes a valley bottom 11b1 that is relatively lower than the other regions, and the circumferential sides thereof are continuously raised to form a valley-shaped concave curved surface. The concave curved surface is formed such that the central portion in the radial direction is low (deep) and the inner diameter side portion and the outer diameter side portion are high. (shallow) so-called bowl shape. Further, when the rotary wing disk 11 is viewed from above, the pair of elliptical valley portions 11b are located at the left-right symmetrical position, and the pair of fan-shaped ridge portions 11a are located at the left-right symmetrical position.

As shown in FIG. 6, the raised portion 11a is formed such that the height gradually increases from the rotation center P toward the outer diameter direction. In addition, FIG. 6 shows a cross section including the ridge line 11a1, but the ridge portion 11a on both sides in the circumferential direction of the ridge line 11a1 is also formed to be higher toward the outer diameter direction. Moreover, in order to fix the rotary wing disk 11 to the washing and dewatering driving device, the bulging portion 11i facing upward is provided around the rotation center P, and the space for accommodating the fixing screw is secured.

The shape of the upper surface of the rotary wing disk 11 will be described in further detail. As shown in Fig. 5, the second inclined surface 11h forming the valley portion 11b is inclined toward the tangent to the boundary 11m of the first inclined surface 11g, and a so-called "downward convex" curved surface is formed. On the other hand, the first inclined surface 11g forming the raised portion 11a is reduced in inclination from the tangent to the boundary 11m of the second inclined surface 11h, and a so-called "upward convex" curved surface is formed. Further, the boundary 11m is formed as a point of change from "downward convex" to "upward convex".

Further, the inclination angle θ h with respect to the second inclined surface 11h immediately before reaching the boundary of 11 m is 30 degrees, and the inclination angle θ g of the first inclined surface 11 g immediately after the boundary of 11 m is 10 degrees, and the inclination angle of the boundary of 11 m is Decreased discontinuously. In this way, the boundary 11m between the first inclined surface 11g and the second inclined surface 11h forms a ridge boundary portion, and the inclination angle is sharply reduced at the ridge boundary portion (the difference in the inclination angle is at least 10 degrees or more).

Therefore, even when the height of the raised portion 11a is not extremely increased when the rotary wing disk 11 is rotated, the washing material can be pushed up by the ridge boundary portion, and the washing power is improved not only by the washing effect at the time of falling, It also promotes the alternation of the laundry located above and below, so the laundry unevenness is also reduced. Here, since the valley portion is gradually inclined continuously from the valley portion to the ridge portion, the washing material on the rotating wing plate is easily slid, the laundry located above is maintained above, and the laundry located below is maintained below. The thread can not be removed, and the thread is likely to remain between the washings or the wrinkles. However, according to the present embodiment, since the upper and lower sides of the washings are promoted alternately, it is easy to take out the thread ends together with the water, and the collection rate of the thread ends collected and removed by the wire head filter 38 is also increased.

Here, as shown in FIG. 4, the circumferential length Lg of the outer peripheral end of the raised portion 11a is formed to be longer than the circumferential length Lh of the outer peripheral end of the valley portion 11b. In this way, as the outer diameter side moves, the area of the raised portion 11a becomes larger, and the ridge boundary portion as viewed from above has a curved shape. Therefore, it is possible to ensure a long ridge boundary portion and lift the push-up of the washing material. effect. However, since the surface area of the raised portion 11a is designed to be smaller than the surface area of the valley portion 11b, a large amount of the washing material that can be accommodated in the washing and dewatering tank 9 is secured.

In addition, the length of the ridge line 11a1 and the valley bottom 11b1 in the circumferential direction (half the total length of the circumferential direction of the first inclined surface 11g and the circumferential length of the second inclined surface 11h) is formed as the height difference from the ridge line 11a1 to the valley bottom 11b1. Longer. The height of the ridge portion 11a becomes higher as the outer diameter end becomes higher, but the length in the circumferential direction becomes closer to the outer diameter end, so This length relationship is formed without the position of the direction.

The operation of the laundry at the time of washing/drying in the case where the rotary blade 11 is used in the present embodiment will be described. When the rotary wing disk 11 rotates, the washing material on the rotary wing disk 11 rotates in the rotational direction of the rotary wing disk 11, and is pushed upward by the inclined narrowing portion formed at the boundary 11m between the ridge portion 11a and the valley portion 11b. The laundry located below moves to the top.

By alternately rotating the rotary disk 11 in the forward and reverse directions, the vertical direction and the radial direction of the washings in the washing and dewatering tank 9 are promoted. Thereby, the mechanical action in the laundry (the washing action, the washing action, the washing action) does not operate unevenly, and it is possible to reduce uneven laundry and improve the washing power. In addition, it is possible to reduce the unevenness of washing during washing. Further, in the drying, the warm air can be prevented from passing through the washing material unevenly, and the unevenness in drying and the reduction in power consumption and drying time can be reduced. In the present embodiment, since the washing water is sprayed on the washing material from above the washing and dewatering tank 9 so as not to exceed the water level of the washing water, the washing water is spread over the washing material. For the important thing. Therefore, the shape of the upper surface of the rotary wing disk 11 is set to be bilaterally symmetrical, and the operation of the laundry in the circumferential direction is set to be substantially the same as the left and right rotation of the rotary blade 11.

Here, as the height difference between the ridge line 11a1 and the valley bottom 11b1 is larger, the vibration in the vertical direction of the washing material becomes larger, and the washing power is increased. However, if the ridge line 11a1 is too high, the space in the washing and dewatering tank 9 for accommodating the laundry is reduced. Therefore, in the present embodiment, as shown in Fig. 6, the inclination angle of the ridge line 11a1 of the ridge portion 11a in the radial direction (from the ridge line) The inclination angle θ1 from the horizontal plane of 11a1 is set to 10 to 20 degrees with respect to the horizontal plane, and the height of the highest portion of the raised portion 11a, that is, the height of the outer diameter side end of the ridge line 11a1 is suppressed. Further, in the present embodiment, since the raised portion 11a and the valley portion 11b are respectively set to be bilaterally symmetrical, the operation of the laundry does not change regardless of whether the rotary wing 11 is rotated in either of the left and right directions, and thus the cloth is less likely to be entangled or The cloth piece is squeezed on one side, and can suppress uneven laundry and cloth damage.

Further, when the number of rotations of the rotary wing disk 11 is too high, the effect of extruding the washing material to the outside due to the centrifugal force is stronger than the effect of pulling the above-mentioned washing material into the inner side, and the action of the washing agent in the radial direction is deteriorated. . Therefore, the number of rotations of the rotary wing disk is preferably 100 to 130 rotations per minute.

The skirt region (the valley portion 11b) of the ridge portion 11a has a plurality of curved ridges 11d which are curved in the same direction as the boundary 11m. In the present embodiment, as shown in FIG. 4, one ridge 11d is disposed at each of the symmetrical positions with the valley bottom 11b1 interposed therebetween, and is provided at a point symmetrical position with respect to the rotation center P (four in total).

When the rotary disk 11 is rotated, the laundry vibrates up and down on the upper surface of the rotary disk 11, so that the ridge 11d has a washing plate effect and has an effect of improving the cleaning power. However, if the height of the ridge 11d is too high, the action of pulling the laundry becomes large as in the case of the stirring blade (pulley) of a general washing machine, and it becomes a cause of cloth entanglement and cloth damage. Therefore, in order not to hinder the sliding of the washing material, the height of the ridges 11 is preferably 2 to 4 mm. The ridge 11d is disposed in the skirt region (the valley portion 11b) of the ridge portion 11 is Did not increase the damage of the washings.

A plurality of spherical crown-shaped convex portions 11e are provided on the upper surface of the rotary wing 11. The curved convex portion 11e is dispersedly arranged in the valley portion 11b. The curved convex portion 11e also has the same washing plate effect as the above-described protruding strip 11d, and has an effect of improving the detergency. However, if the height of the curved convex portion 11e is too high, the washing slip is reduced and the rotation is performed together with the rotary wing 11. As a result, the vibration in the vertical direction of the washing material becomes small, and the washing power is lowered. Therefore, in order not to hinder the sliding of the washing material, the height of the curved convex portion 11e is preferably 1 to 3 mm and the diameter is 20 to 30 mm.

Specifically, the upper surface of the rotary wing 11 is provided with a plurality of through holes 11c for water supply and ventilation on both sides in the circumferential direction of the raised portion 11a and the valley portion 11b. Here, the through hole 11c is not disposed in the top region near the ridge line 11a1 of the ridge portion 11a, and the ridge 11d and the curved surface portion 11e.

Further, in the drying process, the rotary airfoil 11 unwinds the laundry which is biased on the inner peripheral wall surface of the washing and dewatering tank 9 by the final dewatering, and promotes the upward movement of the washing material by the ridge boundary portion. It not only promotes the alternation of the washing materials to suppress the unevenness of the drying, but also serves to improve the drying efficiency by making the contact between the circulating air and the washing material good.

Fig. 8 is a block diagram of a control unit of the washing and drying machine. 40 is a microcomputer connected to the operation key input circuit 41 connected to each of the switches 6, 6a, the water level sensor 21, the temperature sensor 26, and the vibration sensor 27, and receives the user's key operation, washing work, and Various information signals in the drying project. The output from the microcomputer 40 is connected to the drive circuit 42 and is connected to the water supply solenoid valve 4, the brake 12, and the drain valve. 15. The circulation pump 16, the electric motor 13, the blower fan 19, the heater 20, and the like control the opening, closing, rotation, and energization of the pump. Further, a 7-domain light-emitting diode display 25, a light-emitting diode 7, and a squeaker 43 for notifying the user of the operation state of the washing machine are connected.

In the washing machine of the present embodiment, the water level of the washing water and the washing water stored in the bottom of the outer tank 10 in the laundry and washing works must basically be prevented from rising to the immersion, and the rotating wing 11 is reversed. The rotating side circulates the washing water so that the washing water stored at the bottom of the outer tank 10 substantially exceeds the upper surface of the rotating wing 11 so that the washing water on the rotating wing 11 floats. However, if the washings on the rotary wing 11 contain a large amount of washing water, and the rotation of the rotating airfoil 11 and the circulation of the washing water are stopped for a long period of time, the washing water and the washing water circulation system contained in the washings are The inside washing water is stored at the bottom of the outer tub 10 by gravity flow, thereby allowing the washing water level in this state to exceed the upper surface of the rotary wing disc 11.

Therefore, in the present embodiment, as the set water level for controlling the water supply to the washing water, a water level slightly lower than the height below the rotary wing 11 in the washing and dewatering tank 9 is set at the time of washing of the washing material of a normal cloth amount. H1, setting a water level slightly higher than the aforementioned water level h1 (about 10 cm) at a washing time of the laundry which is less than the usual amount of cloth (approximately equal to the ridge of the rotating wing 11 in the washing and dewatering tank 9) The water level of the highest part of the top portion of the portion 11a) h2.

Further, in the water supply project, a predetermined amount of water is supplied, and the powder lotion to which the amount of the washing material is supplied is dissolved to form a high lotion concentration. Laundry water. In the laundry process, the washing water of the high lotion concentration stored at the bottom of the outer tank 10 is sprinkled on the washing machine by circulating the rotating wing disk 11 in a state where the washing and dewatering tank 9 is stationary. The laundry of the washing water having a high lotion concentration is moved up and down by the bulging portion 11a, and is repeatedly pushed up to vibrate to perform washing.

In the washing process, the water is washed in the same water level as the laundry, and is circulated in such a manner that the rotating wing 11 is rotated in the reverse direction while the washing and dewatering tank 9 is stationary, and is stored at the bottom of the outer tank 10. The washing water is sprinkled on the washing material, and the washing liquid containing the washing water is moved up and down on the rotary wing plate 11 to be washed out by the extrusion washing water.

In the drying process, the rinsing in the washing and dewatering tank 9 after the centrifugal dewatering is stirred by the forward and reverse rotation of the rotary wing 11, and the humid air in the outer tank 10 is sucked out. After being cooled and dehumidified by water, it is heated and blown into the washing and dewatering tank 9.

The microcomputer 40 is started by pressing the power switch 5 to input power, and the basic control processing program for washing and drying as shown in Figs. 9 and 10 is executed.

Step S106

The lotion feed water solenoid valve is opened, and the lotion feed water is supplied to the lotion input chamber of the lotion ‧ final softener container 28. The user operates to put the displayed powder washing dose into the lotion ‧ and finally the lotion agent container 28 is put into the chamber, and then the outer lid 3 is closed. The powder lotion which is put into the lotion supply chamber in which the lotion feed water flows is dropped to the bottom of the outer tank 10 through the lotion ‧ final softener inlet 28a together with the water of the lotion feed water.

Step S107

When the lotion is dissolved and the water is supplied to the water level, the water supply is stopped. In the present embodiment, the amount of the lotion (the amount of cloth) is set to about 10 liters. When the washing and dewatering tank 9 is rotated in the subsequent lotion dissolving process (step S108), the amount of water is sufficient to stir the amount of water and lotion supplied from the bottom of the washing and dewatering tank 9, and the water surface is set low. The height below the rotating wing disk 11 (the laundry does not get wet before the lotion dissolves).

Step S108

By gradually rotating the washing and dewatering tank 9 and the rotary wing 11 in one direction (about 70 rotations per minute), the lotion dissolved water and the liquid to be poured into the bottom of the outer tank 10 are stirred on the bottom surface of the washing and dewatering tank 9 The powder lotion is dissolved in a washing water lotion which produces a high lotion concentration.

Step S109

This pre-washing is performed while the washing and dewatering tank 9 is stationary, and the stirring of the rotary disk 11 is performed intermittently in the reverse direction, and the circulation pump 16 is operated during the forward and reverse rotation of the rotary disk 11. The washing water at the bottom of the outer tank 10 is sprinkled from the nozzle 34 onto the laundry. During the stop period of the rotary wing disk 11 and the circulation pump 16, while referring to the detection signal of the water level sensor 21, the lotion water supply solenoid valve and the wash water supply solenoid valve are opened to supply water and the water level does not exceed the set water level. By repeating this operation a plurality of times, the washing liquid is allowed to permeate the washing water and dispersed on the rotary wing disk 11.

At the time of the first forward/reverse rotation, the washing water having a concentration of about 7 times of the lotion was sprinkled onto the laundry and soaked into the laundry. Since the high concentration of the wash water is sprinkled from the nozzle 34 to the laundry, there is no uneven penetration into the laundry by the penetration of the lotion. The high-concentration washing water soaked in the washing material has high dissolving power and can dissolve grease and dirt, so that the effect of the dirt floating out of the washing material is very large, and high detergency is obtained.

By repeating the replenishment of water, the concentration of the lotion which is sprayed on the washing water of the washing material gradually decreases, and becomes about twice the standard concentration at the end of the pre-washing.

Step S110
