In the upper surface plate 12, an input port 14 for feeding the laundry is formed. The inlet 14 is covered by a freely open upper cover 15.

Inside the casing 10, the outer tub 20 is elastically suspended by four booms 21 having anti-vibration means. The upper surface of the outer tub 20 is covered by the outer tub cover 22. In the outer tub cover 22, an opening 22a having substantially the same size as the input port 14 is formed at a position corresponding to the input port 14. The opening portion 22a is covered by the inner lid 23 so as to be openable and closable.

In the outer tub 20, a substantially cylindrical washing and dewatering tub 24 whose upper surface is opened is disposed. On the inner wall surface 24a of the washing and dewatering tub 24, a plurality of dewatering holes 24b are formed over the entire circumference. At the upper portion of the washing and dewatering tub 24, a balance ring 25 is provided. At the bottom of the washing and dewatering tub 24, a pulsator 26 is disposed.

At the outer bottom of the outer tub 20, a drive unit 30 that generates a torque that drives the washing and dewatering tub 24 and the pulsator 26 is disposed. The drive unit 30 includes a drive motor 31 and a transmission mechanism portion 32. The transmission mechanism portion 32 has a clutch mechanism by which the torque of the drive motor 31 is transmitted only to the pulsator 26 and only the pulsator 26 is rotated during the washing process and the rinsing process, during the dehydration process, The torque of the drive motor 31 is transmitted to the pulsator 26 and the washing and dewatering tub 24 to integrally rotate the pulsator 26 and the washing and dewatering tub 24.

At the outer bottom of the outer tub 20, a drain port portion 20a is formed. A drain valve 40 is provided in the drain port portion 20a. The drain valve 40 is connected to the drain hose 41. When the drain valve 40 is opened, the water stored in the washing and dewatering tub 24 and the tub 20 is discharged to the outside of the body through the drain hose 41.

At the rear of the upper surface plate 12, a housing portion 12a having an open upper surface is provided. The upper surface of the housing portion 12a is covered by the rear cover 16. In the accommodating portion 12a, a drying device 50 for drying the laundry in the washing and dewatering tub 24 and a water supply device (not shown) for supplying water into the outer tub 20 are housed.

Next, the configuration of the pulsator 26 will be described in detail.

FIG. 2 is a perspective view of the pulsator 26 of the present embodiment.

The pulsator 26 includes a substantially disk-shaped susceptor 100, two blade portions 110 formed on the surface of the susceptor 100 at intervals of 180 degrees, and two wall portions 120 formed on the outer periphery of the susceptor 100. Base 100 The surface is slowly inclined upward toward the center portion 101.

Each of the blade portions 110 extends radially from the central portion 101 of the susceptor 100 to the outer peripheral edge. In each of the blade portions 110, a flat inclined surface 112 for pushing the laundry upward is formed on both sides of the top portion 111 extending in the horizontal direction in a straight line. The inclination angle α of the inclined surface 112 with respect to the surface perpendicular to the rotation axis direction X of the pulsator 26 is, for example, 45 degrees. When the inclination angle α is too small, when drying by the drying device 50, when the pulsator 26 is rotated, the laundry that climbs the inclined surface 112 cannot be lifted up high. On the contrary, when the inclination angle α is excessively large, it is difficult for the laundry to climb up the inclined surface 112 when the pulsator 26 rotates. Therefore, it is preferable that the inclination angle α is set in the range of 30 degrees to 60 degrees.

A plurality of water passing holes 130 are formed in the surface of the susceptor 100 and the blade portion 110. The water passing hole 130 passes water to the back side of the pulsator 26.

The wall portion 120 is formed in an arc shape so as to be along the outer periphery of the susceptor 100. When the pulsator 26 rotates, when the laundry placed on the surface of the susceptor 100 is to be moved toward the inner wall surface 24a side of the washing and dewatering tub 24 by centrifugal force, the wall portion 120 blocks the laundry from being inclined toward the blade portion 110. Face 112. Thereby, the laundry is well inverted by the inclined surface 112.

Next, the configuration of the drying device 50 will be described in detail.

3 is a perspective view showing the upper surface plate 12, the outer tub cover 22, and the drying device 50 in a state in which the drying device 50 is provided in the housing portion 12a of the upper surface plate 12 according to the present embodiment. 4(a) is a perspective view of the drying device 50 in a state where the upper casing 203 is removed in the present embodiment, and FIG. 4(b) is a drying state in which the upper casing 203 and the blower 204 are removed in the present embodiment. A perspective view of device 50. 5(a) and 5(b) are a perspective view and a side view, respectively, of the nozzle 230 of the present embodiment. FIG. 6 is a view for explaining a direction of the air outlet 231 of the nozzle 230 when the washing and dewatering tub 24 is viewed from above in the present embodiment. It should be noted that in FIG. 3, the upper surface plate 12 is drawn in a transparent state for the sake of convenience. Further, in FIGS. 3, 4(a), and 4(b), for the sake of convenience, the nozzle 230 is drawn to face the front direction of the upper surface plate 12 more than actually.

The drying device 50 includes a warm air generating unit 200, an intake duct 210, an exhaust duct 220, and a nozzle 230.

The warm air generation unit 200 is provided with a casing 201. The outer casing 201 is formed by joining the lower casing 202 having the upper surface open to the upper casing 203 having the lower surface opening. In the lower casing 202, a suction port 202a is formed and The discharge port 202b.

A blower 204 and a heater 205 are provided in the outer casing 201. The blower 204 is a high air volume/high static pressure type centrifugal fan, and includes a fan 204a and a fan motor 204b for rotating the fan 204a. The fan 204a is disposed to face the suction port 202a in the outer casing 201, and the fan motor 204b is disposed on the outer top surface of the outer casing 201. The maximum air volume of the blower 204 is, for example, about 3 m ³ /min, and the maximum static pressure is, for example, about 11 kPa. The heater 205 is, for example, a PTC heater that heats the wind passing through the inside thereof. The heater 205 is disposed inside the casing 201 between the blower 204 and the discharge port 202b.

The intake duct 210 extends in the horizontal direction, has an exhaust port 211 on the upper surface on one end side, and an intake port 212 on the lower surface on the other end side. The exhaust port 211 is connected to the suction port 202a of the outer casing 201.

The exhaust duct 220 is a flexible duct formed of an elastic material such as rubber and has a bellows portion 221 at an intermediate portion. The upper end portion 222 of the exhaust duct 220 is connected to the discharge port 202b of the outer casing 201. As shown in FIG. 3, in the outer tub cover 22, an introduction port 22b is formed behind the opening 22a, and a lower end portion 223 of the exhaust duct 220 is connected to the introduction port 22b.

The upper portion 230a of the nozzle 230 has a cylindrical shape, and the lower portion 230b has a tapered shape and extends obliquely downward. At the top end of the lower portion 230b of the nozzle 230, a circular air outlet 231 is formed. In the present embodiment, the opening angle β of the opening direction D of the air outlet 230 with respect to the axial direction L of the nozzle 230 is, for example, 45 degrees.

An annular flange portion 232 is formed at the upper end of the nozzle 230, and a plurality of insertion holes 233 are formed in the flange portion 232. The nozzle 230 is attached to the introduction port 22b of the outer tub cover 22 from below. At this time, a screw (not shown) that passes through the insertion hole 233 of the flange portion 232 is fixed to the periphery of the introduction port 22b. The nozzle 230 is connected to the lower end portion 223 of the exhaust duct 220 via the introduction port 22b.

In a state where the nozzle 230 is attached to the outer tub cover 22, the axial direction L of the nozzle 230 is parallel to the vertical direction, whereby the air outlet 231 of the nozzle 230 has an opening angle β of, for example, 45 degrees from the vertical direction, and is inclined downward. direction. When the opening angle β of the air outlet 231 is too small, that is, when the opening direction D of the air outlet 231 is too close to the direct downward direction, the downward momentum of the warm air blown from the air outlet 231 becomes too strong, and the up and down movement of the laundry becomes difference. On the other hand, when the opening angle β of the air outlet 231 becomes excessively large, that is, when the opening direction D of the air outlet 231 is too close to the horizontal direction, the downward momentum of the warm air blown from the air outlet 231 becomes excessive. It is weak, and the wrinkle smoothing effect of the laundry described later becomes small. Thus, the outlet It is preferable that the opening angle β of 231 is set in the range of 30 degrees to 60 degrees.

Further, as shown in FIG. 6, the nozzle 230 is disposed in the vicinity of the inner wall surface 24a of the washing and dewatering tub 24 so as to avoid the balance ring 25 at the upper portion of the washing and dewatering tub 24. Then, the orientation of the nozzle 230 is set such that the air outlet 231 opens in a direction that does not face the center P of the pulsator 26 when the washing and dewatering tub 24 is viewed from above. In other words, when the clockwise direction of FIG. 6 is the forward rotation direction A of the pulsator 26 and the counterclockwise direction of FIG. 6 is the reverse rotation direction B of the pulsator 26, the air outlet 231 faces the reverse direction B side. It should be noted that the air outlet 231 may also face the normal rotation direction A side. Further, as shown by the ellipses in FIG. 6, the direction of the air outlet 231 is an area on the outer circumference side which is half the center P of the pulsator 26, that is, the length of 1/2R shown in FIG.

Next, the operation of the fully automatic washing and drying machine 1 will be described.

In the fully automatic washer-dryer 1, the washing operation, the washing and drying operation, or the drying operation of various operation modes are performed. The washing operation is an operation in which only washing is performed, and the washing process, the intermediate dehydration process, the rinsing process, and the final dehydration process are sequentially performed. The washing and drying operation is a continuous washing to drying operation, and then the final dehydration process is performed. The drying operation is an operation in which only drying is performed, and only the drying process is performed.

In the washing process and the rinsing process, the pulsator 26 is rotated in the forward rotation direction A and the reverse rotation direction B in a state where water is stored in the washing and dewatering tub 24. A flow of water is generated in the washing and dewatering tub 24 by the rotation of the pulsator 26. During the washing process, the laundry is washed by the generated water stream and the detergent contained in the water. During the rinsing process, the laundry is rinsed through the resulting water stream.

During the intermediate dewatering process and the final dewatering process, the washing and dewatering tub 24 and the pulsator 26 are integrally rotated at a high speed. The laundry is dehydrated by the action of centrifugal force generated in the washing dewatering bucket 24.

During the drying process, the blower 204 and the heater 205 operate in the drying device 50. When the blower 204a of the blower 204 rotates, the outside air is sucked into the intake duct 210 from the intake port 212, and the air passing through the intake duct 210 is sucked into the blower 204a in the outer casing 201 through the suction port 202a. The wind is sent from the blower 204a, and the sent air is heated by the heater 205 to become warm air. The warm air is discharged from the discharge port 202b and passes through the exhaust duct 220 to reach the nozzle 230. Then, the warm air is blown vigorously from the air outlet 231 of the nozzle 230 toward the bottom of the washing and dewatering tub 24, that is, the region on the outer peripheral side of the pulsator 26 shown in Fig. 6 . In the present embodiment, the flow rate of the warm air immediately after being blown out from the air outlet 231 of the nozzle 230, That is, the initial flow rate is about 100 m/s. In addition, it is preferable that the initial flow rate is 50 m/s or more, and it is preferable to set it as 80 m/s or more. As described above, the warm air blown from the air outlet 231 is greatly enhanced from the warm air current of about 20 m/s which is blown into the washing and dewatering tub 24 in the conventional drying process.

In the washing and dewatering tub 24, the pulsator 26 repeats the rotation of the forward rotation direction A and the rotation of the reverse rotation direction B.

7(a) and 7(b) are diagrams schematically showing the movement of the laundry in the washing and dewatering tub 24 in the drying process of the present embodiment. In Fig. 7 (a) and Fig. 7 (b), only the pulsator 26, the nozzle 230, and the laundry are drawn.

When the pulsator 26 rotates, as shown in FIG. 7(a), the laundry is pushed by the blade portion 110 of the pulsator 26, and slides on the inclined surface 112 of the blade portion 110, whereby the laundry is moved toward the blade portion 110. Flip the top of the direction. In the case where the pulsator 26 is rotated in the normal rotation direction A, the warm air from the nozzle 230 is violently blown toward the laundry from a direction opposite to the direction in which the reversed laundry advances. As shown in Fig. 7(b), on the laundry, the acceleration force in the traveling direction and the blowing force of the warm air act in opposite directions, and therefore, the laundry is spread in the horizontal direction by these forces, and the wrinkles of the laundry are Smooth. Moreover, the laundry is dried by the warm air that is contacted. When the pulsator 26 is agitated, the laundry is easily collected by the centrifugal force to the outer peripheral side of the pulsator 26. However, since the direction of the outlet 231 of the nozzle 230 is the outer peripheral side of the pulsator 26, the warm air is easily contacted. To the laundry that is turned over on the outer peripheral side.

In the present embodiment, when the pulsator 26 is rotated in the forward rotation direction A, the warm air is easily and effectively contacted. Thereby, in the drying process, it is preferable to increase the rotation frequency of the pulsator 26 in the forward rotation direction A.

As described above, according to the present embodiment, since the warm air is blown from the nozzle 230 to the laundry that is turned upward by the action of the inclined surface 112 of the pulsator 26, the laundry is easily inside the washing and dewatering tub 24. Unfolding, it is not easy to produce wrinkles on the laundry during drying.

Further, according to the present embodiment, since the direction of the air outlet 231 of the nozzle 230 is the region on the outer circumferential side of the pulsator 26, the warm air from the air outlet 231 is easily contacted to the pulsator by the centrifugal force when the pulsator 26 is rotated. The laundry on the outer peripheral side of 26 and turned over on the outer peripheral side. Thereby, it is easy to further reduce the occurrence of wrinkles of the laundry.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications other than the above may be made in the embodiments of the present invention.

8(a) and 8(b) are a perspective view and a side view, respectively, of the nozzle 240 of Modification 1.

During the drying process, as shown in FIG. 10(a), when the pulsator 26 is rotated in the forward rotation direction A, the rotation is performed. The mechanism unit 250 rotates the nozzle 240 in the clockwise direction as viewed from above, and positions the nozzle 240 at the first rotational position in which the air outlet 241 faces the reverse direction B side. Thereby, the warm air from the air outlet 241 is in good contact with the laundry which is turned upward in the normal rotation direction A by the rotation of the pulsator 26 in the normal rotation direction A.

On the other hand, in the drying process, as shown in FIG. 10(b), when the pulsator 26 is rotated in the reverse direction B, the rotation mechanism portion 250 rotates the nozzle 240 in the counterclockwise direction when viewed from above, and The nozzle 240 is located at a second rotational position in which the air outlet 241 faces the normal rotation direction A side. Thereby, the warm air from the air outlet 241 is in good contact with the laundry which is turned upward and reversed in the reverse direction B by the rotation of the pulsator 26 in the reverse direction B.

As described above, according to the configuration of the present modification, the warm air from the air outlet 241 can be brought into good contact with the pulsator 26 regardless of the direction in which the pulsator 26 rotates in the forward rotation direction A and the reverse rotation direction B. Washing. Thereby, the wrinkle smoothing effect of the laundry can be improved.

FIG. 11 is a perspective view of the pulsator 27 of Modification 3.

Instead of the pulsator 26 of the above embodiment, the pulsator 27 of the present modification may be used.

The pulsator 27 includes a substantially disk-shaped susceptor 300 and three blade portions 310 formed on the surface of the susceptor 300 at intervals of 120 degrees. Each of the blade portions 310 extends radially from the central portion 301 of the susceptor 300 to the outer peripheral edge. In each of the blade portions 310, a flat inclined surface 312 for pushing the laundry upward is formed on both sides of the top portion 311 extending in the horizontal direction in a straight line. The inclination angle α of the inclined surface 312 with respect to the surface perpendicular to the rotational axis X of the pulsator 27 is, for example, 45 degrees. A plurality of water passing holes 320 are formed in the surface of the base 300 and the blade portion 310. The water passing hole 320 passes water to the back side of the pulsator 27.

In addition, similarly to the pulsator 26 of the above-described embodiment, the inclination angle α of the three blade portions 310 is preferably set in the range of 30 degrees to 60 degrees.
