  However, in the conventional configuration, even if the rotating drum is rotated at a high speed in the dehydrating process and the water is attached to the surface of the laundry even after centrifugal dewatering, the laundry is stuck to the inner wall of the rotating drum, Even if the rotating drum stops at the end of the dehydration process, the laundry does not come off and adheres to the inner wall of the rotating drum, so it is difficult to take out the laundry. Therefore, there was a possibility of forgetting to put it out. Further, when the drying process is performed after the dehydration process, the laundry dries while the laundry is stuck to the rotating drum, and thus there is a problem that the drying cannot be finished softly due to a large amount of uneven drying and wrinkles. Therefore, in order to solve the above problems, the preliminary dehydration in which the rotating drum is rotated at a low speed before the dewatering process and the rotating drum are rotated alternately at the left and right speeds to separate the laundry, and after the final dewatering process, the separation process is provided to provide the laundry. Although it is also peeled off, if the laundry is more than a predetermined amount, some of the laundry begins to peel off due to the weight of the laundry, and the tangled laundry is gradually peeled off in a chain, or the peeling Since several pieces of the washed laundry are agitated and frequently hits the laundry stuck to the inner wall of the rotating drum, the stuck laundry begins to peel off gradually, and all the laundry peels off at the end of the peeling process, but the laundry is In the case of the fixed amount or less, since the laundry is not peeled off by its own weight, it remains attached to the inner wall of the rotating drum even after the peeling process is finished, and has the same problem as described above.

By opening the lid 23, the laundry can be taken in and out of the rotary drum 5 through the clothing entrance 24. ing. Since the lid body 23 is provided on the upward inclined surface, the laundry can be carried out without bending the waist. The water receiving tank 3 is suspended from the main body 1 so as to be swingable by a spring body 26 and a damper 2, and a drain groove 25 is provided at a lower portion of the water receiving tank 3 in a direction perpendicular to the rotation direction of the rotary drum 5. One end of a drainage path 26 is connected to the drainage groove 25, and the other end of the drainage path 26 is connected to a drainage valve 27 so that the washing water in the water receiving tub 3 is drained. The water supply valve 9 for supplying water supplies water into the water receiving tank 3 through the water supply path 28. The water level detection means 29 detects the water level in the water receiving tank 3.

  Next, the configuration and operation of the drying function will be described with reference to FIGS.

  2 and 3, the drying function includes a heater 16 that is a typical heating unit, a blower fan 14 that is a typical blower unit, and a fan case 30 that accommodates the heater 16 and the blower fan 14 therein. The fan case 30 is attached to the main body 1. In the water receiving tank 3, an exhaust port 31 for taking in the air in the water receiving tank 3 is provided in the body portion of the water receiving tank 3, and the air blowing port 32 is located on the back surface of the water receiving tank 3 and in the vicinity of the outer periphery of the rotating drum 5. It is provided to do. The water receiving tank 3 is integrally provided with a heat exchange member accommodation chamber 33 so that one end communicates with the exhaust port 31. The other end of the heat exchange member accommodation chamber 33 is connected to the first bellows hose 34 and the thread. It is connected to the intake end 36 of the fan case 30 through a waste collection filter 35. On the other hand, the exhaust end 37 of the fan case 30 has a second bellows hose 38 at the other end of the air duct 3a provided integrally with the water receiving tank 3 so that one end communicates with the air blowing port 32 of the water receiving tank 3. Connected. Further, a back surface through-hole 39 is provided at a position corresponding to the air blowing port 32 on the back surface of the rotating drum 5, and air blown from the air blowing port 32 is blown into the rotating drum 5. In the heat exchange member accommodation chamber 33, a plate-like aluminum or resin heat exchange member (heat exchanger) 40 is attached above the exhaust port 31 so as to be inclined downward from the front side toward the back side. The heat exchange member accommodation chamber 33 is divided by the heat exchange member 40 into a lower heat exchange member accommodation chamber 41 and an upper heat exchange member accommodation chamber 42. The lower heat exchange member accommodation chamber 41 and the upper heat exchange member accommodation chamber 42 are The heat exchange member 40 communicates with the lower end portion 44 via the communication port 43, and the path is substantially U-shaped. The cooling water supply valve 10 supplies cooling water from the water supply cap 45 to the upper end 46 of the heat exchange member 40 via the cooling hose 18. The cooling water supply valve 10, the cooling hose 18, and the water supply cap 45 constitutes a cooling water supply means.

  In the drying process, as shown by the white arrow, the air blown by the rotation of the blower fan 14 is heated to a predetermined temperature by the heater 16 and is sent from the blower opening 32 through the second bellows hose 38 and the blower duct 3a. Air is blown into the water receiving tub 3 and further blown into the rotary drum 5 from the rear through-hole 39. The heated hot air takes moisture from the wet laundry in the rotating drum 5 in a state of being stirred, and becomes hot air having moisture. Thereafter, the hot air having moisture passes through the through hole 7 from the inside of the rotating drum 5, is discharged to the water receiving tank 3, and is further blown from the exhaust port 31 to the heat exchange member accommodation chamber 33.

  At this time, the cooling water supply valve 10 is in the ON state, and the cooling water falls from the water supply base 45 to the upper end portion 46 side of the heat exchange member 40, and the upper surface 40a of the heat exchange member 40 is moved along the broken line arrow. It flows and falls from the tip of the lower end 44 of the heat exchange member 40 to the lower heat exchange member accommodation chamber 41 side. Thereafter, the cooling water is discharged into the water receiving tank 3 from a drain hole 48 provided on the bottom surface of the lower heat exchange member accommodating chamber 33 and communicating with the water receiving tank 3, and is discharged outside the apparatus through the drainage path 26. The The wet warm air sent into the lower heat exchange member accommodation chamber 41 of the heat exchange member accommodation chamber 33 through the exhaust port 31 first contacts the lower surface 40 b of the heat exchange member 40. At this time, since the lower surface 40b of the heat exchange member 40 is also cooled by the cooling water flowing through the upper surface 40a of the heat exchange member 40, heat exchange is performed between the wet warm air and the lower surface 40b of the heat exchange member 40. The action is performed, and the wet warm air is dehumidified (first dehumidifying step). Further, the wet warm air is sent to the upper heat exchange member accommodating chamber 42 on the lower end portion 44 side of the heat exchange member 40 through the communication port 43. The cooling water falling from the lower end portion 44 is rolled up and scattered, heat exchange is performed with the scattered cooling water, and the moist hot air is dehumidified (second dehumidifying step). Thereafter, the wet warm air is sent to the upper heat exchange member accommodation chamber 42 and comes into contact with the upper surface 40a of the heat exchange member 40 and the cooling water flowing therethrough. At this time, the direction in which the cooling water flows and the direction in which the wet warm air flows are opposed to each other. Thereby, the moist warm air is subjected to heat exchange action with the upper surface 40a of the heat exchange member 40 and the cooling water flowing therethrough, and the moist hot air is dehumidified (third dehumidification step).

  Thus, the humid hot air that has passed through the three dehumidifying steps of the first dehumidifying step, the second dehumidifying step, and the third dehumidifying step becomes air that has been efficiently cooled and dehumidified, and the first bellows hose 34, the lint collection The air is sent from the intake end 36 of the fan case 30 into the fan case 30 through the filter 35 and sent to the blower fan 14.

  Thereafter, the laundry is gradually dried by the air circulation as described above, and the drying process is finished after a predetermined time has elapsed or when the laundry reaches a predetermined dryness.

  In the drum type washing and drying machine having the above-described configuration, the washing process, the rinsing process, the dehydrating process, and the drying process are executed by the control operation of the control device 51.

  FIG. 4 shows the configuration of the control device 51. The control means 52 constituted by a microcomputer displays on the display means 55 in accordance with a setting input such as selection of a driving course inputted from the setting means 54. The control command is output to the power switching unit 53 using the control program stored in the storage unit 56. The power switching unit 53 is configured using a switching element such as an SCR, and according to a control command output from the control means 52, the motor 6, the water supply water supply valve 9, the drain valve 27, the heater 16, the blower fan 14, and the cooling device. ON / OFF control of the water supply valve 10 and the like is performed.

  The lid 23 is opened, the laundry is put into the rotating drum 5, a required amount of detergent is put into the detergent inlet connected to the water supply water supply valve 9, and the power switch 58 is turned on. The control means 52 stores a control program corresponding to the setting input by selecting and inputting a driving course according to the type of the laundry from the setting means 54 on the operation panel provided on the surface and inputting the operation start. The data is read from the means 56 and a control operation corresponding to the control procedure is started. First, the control means 52 detects the amount of laundry by rotating the rotary drum 5. Since the cloth amount detection means 57 detects the amount of laundry from the load change received by the motor 6 according to the amount of laundry, the detected amount of laundry is input to the control means 52 and stored in the storage means 56. The

  First, a washing process is started, and water supply control and rotation control of the rotary drum 5 are executed. The control means 52 opens the water supply valve 9 for supplying water and outputs a control command for supplying water into the water receiving tub 3 to the power switching unit 53. At the same time, the control command for driving the rotary drum 5 to rotate at the first predetermined rotation speed is provided. Output to the switching unit 53. By this control operation, the water supply valve 9 for water supply is opened and tap water is supplied through the water supply path 28, and water mixed with detergent is supplied into the water receiving tank 3.

  The water level in the supplied water receiving tank 3 is detected by the water level detecting means 29 provided in the water receiving tank 3, and when the water level becomes the first predetermined water level for performing the washing operation, the water level detecting means 29 Since the detection output is input to the control means 52, the control means 52 outputs a control command for closing the water supply water supply valve 9 to stop the water supply to the power switching unit 53 and the water supply is stopped.

  Thereafter, the rotary drum 5 is rotationally driven by the motor 6 at the first predetermined rotational speed. The first predetermined rotation speed is when the laundry stored in the rotary drum 5 is lifted in the rotation direction by the rotation of the rotary drum 5 and moves to a height position where the weight of the laundry is higher than the inertia and centrifugal force associated with the rotation. It is a rotational speed which shows the behavior which falls on the downward inner peripheral surface of the rotating drum 5.

  Projecting plates 22 are provided at a plurality of positions on the inner peripheral surface of the rotating drum 5, and when the rotating drum 5 rotates at a predetermined speed, the projecting plate 22 rotates by hooking the laundry in contact with the inner peripheral surface of the rotating drum 5. Lift in the direction. Since the laundry falls when its own weight is lifted up to a height position superior to the inertia and centrifugal force associated with the rotation, the laundry accumulated in the rotating drum 5 is also lifted one after another and moved, and falls from above. At the same time as the accumulated state is separated, the laundry is given a washing action by the impact of dropping.

  At this time, the rotation direction is switched between the normal rotation direction and the reverse rotation direction at predetermined time intervals, and the water supplied into the water receiving tank 3 is supplied from the through holes 7 formed in the peripheral surface of the rotation drum 5 to the rotation drum 5. Since it also penetrates into the inside, the detergent foam will uniformly adhere to the dirt on the laundry, and the effect of tapping will be improved.

  When the rotational speed is lower than the first predetermined rotational speed, the action of lifting the laundry does not occur, and conversely, the centrifugal force increases at a rotational speed faster than the first predetermined rotational speed. It will stick to and will not fall.

  When the washing operation is performed for a predetermined time, the control unit 52 outputs a control command for stopping the rotation of the motor 6 to the power switching unit 53, so that the rotation of the rotating drum 5 is stopped and the washing process is finished.

  After the washing process, the rinsing process is started. The control means 52 sequentially outputs a control command to open the drain valve 27 and a control command to drive the motor 6 to the power switching unit 53 to drain the detergent water in the water receiving tub 3 and remove excess detergent water contained in the laundry. The rotating drum 5 is driven at high speed to dehydrate. After that, the laundry is rinsed with water supplied from the water supply valve 9 in the same manner as that performed in the washing process. When the number of times of rinsing inputted in advance by the setting means is executed, the control means 52 outputs a control command for stopping the rotation of the motor 25 to the power switching unit 53, so that the rotation of the rotary drum 5 is stopped and the rinsing process is completed. To do. The control means 52 outputs a control command to open the drain valve 27 to the power switching unit 53 to drain the rinse water in the water receiving tank 3.

  Next, FIG. 5 shows the number of rotations of the rotating drum 5 during the dehydration process.

  In the dehydration process, the rotating drum 5 is rotated at a low speed N1 (for example, 50 r / min) alternately on the left and right, and the cloth unraveling process is performed to loosen the tangled laundry, and the rotation speed N2 (for example, the laundry sticks to the inner wall of the rotating drum 5) 80 r / min), a cloth balancing process for gradually increasing the speed to 80 r / min), a cloth unbalance determining process for determining the displacement of the laundry at the rotational speed N2, and a final dehydrating process for rotationally driving the laundry at a high speed N3 (for example, 1000 r / min). , And the rotating drum 5 is rotated at a low speed N4 (for example, 50 r / min) alternately to the left and right, and a peeling process for peeling the laundry stuck to the inner wall of the rotating drum 5 is sequentially performed.

  Next, a control command for rotationally driving the rotary drum 5 at each stroke at a predetermined rotational speed is output to the power switching unit 53. Here, since the rotary drum 5 is disposed so that the axial center direction of the rotary drum 5 is inclined downward from the front side to the back side, the rotary drum 5 rotates from the rotation speed N1 of the cloth unwinding process to the rotation of the cloth balancing process. During the period up to several N2, the laundry gradually moves to the back surface of the rotating drum 5, and since the laundry contains moisture, it adheres closely to the cylindrical inner wall near the back surface of the rotating drum 5 through the moisture. Thereafter, while the laundry is stuck to the vicinity of the back surface of the rotating drum 5, the rotating drum 5 is driven at the rotational speed N3 and is centrifugally dehydrated.

  Here, in parallel with the rotational drive of the rotary drum 5, when the control means 52 outputs a control command for driving the blower fan 14 and the heater 16 to the power switching unit 53, the air in the water receiving tank 3 is discharged from the exhaust port 31. Then, the air is heated by the heater 16 through the heat exchange member housing chamber 33 and the yarn waste collecting filter 35, and is blown as hot air into the air outlet 32 through the fan case 30 and the air duct 3a. Since the blown hot air is located in the vicinity of the outer periphery of the rotating drum 5, the blown hot air is disposed on the back surface of the rotating drum 5 in the vicinity of the laundry stuck to the inner wall near the back surface of the rotating drum 5 in the cloth balancing process. The laundry is efficiently sprayed on the laundry through the rear through holes 39 and the many through holes 7 arranged on the outer periphery of the rotary drum 5, and the conduction heat from the vicinity of the back of the rotary drum 5 is transmitted to the laundry. Since moisture is gradually removed from the laundry during the final dehydration process, the adhesion of the laundry to the rotating drum 5 is reduced.

  After that, when the control unit 52 outputs a control command with the rotational speed of the rotary drum 5 being N4, the laundry stuck to the inner wall near the back of the rotary drum 5 is easily peeled off, and at the end of the dehydration process. Since all the laundry is peeled off in the rotary drum 5, when the lid 23 is opened and the laundry is taken out, it is easy to take out and the laundry remains attached to the upper surface of the inner wall of the rotary drum 5. I don't forget to put it out because there is nothing.

  The control means 52 turns on the cooling water supply valve 10 and allows cooling water to flow from the water supply cap 45 through the cooling hose 18 to operate the drying function in the same manner as the drying process, thereby further increasing the dehumidifying effect and peeling. The laundry can be easily peeled off during the process.

  In order to take away moisture from the laundry, the blower fan 14 and the heater 16 were turned on and hot air was blown onto the laundry. However, even if only the blower fan 14 was turned on, a rear through-hole provided on the rear surface of the rotary drum 5 during the final dehydration process. 39 and a large number of through-holes 7 provided on the outer periphery of the rotating drum 5 so that the laundry can be efficiently sprayed. And the laundry stuck to the inner wall of the rotary drum 5 is easily peeled off during the peeling process.

  In addition, a preliminary dewatering process in which the rotation speed N3 of the final dewatering process in FIG. 5 is lowered (for example, 450 r / min) is added as a previous process of the dewatering process, and the blower fan 14 and the heater 16 or the When only the blower fan 14 is turned on, there is an effect in peeling the laundry in the peeling process.

  In addition, after the washing process, the rinsing process, and the dehydrating process are completed, the drying process can be executed to dry the dehydrated laundry by the setting means 54. Since it is easily peeled off from the inner wall, the warm air is uniformly applied to the laundry being stirred at the time of drying, and it becomes possible to achieve a soft finish with reduced drying unevenness and wrinkles of the laundry.

  As described above, in the drum type laundry dryer according to the present invention, all the laundry is easily peeled off from the inner wall of the rotating drum at the end of the dehydration process. I will never forget. In addition, when the drying process is performed following the dehydration process, all the laundry is peeled off from the inner wall of the rotating drum, so the warm air can be applied uniformly to the laundry so that it can be softly finished without uneven drying and wrinkles. It is useful as a drum-type washing and drying machine that sequentially controls each process such as washing, rinsing, dewatering, and drying in a rotating drum having a rotation center axis in the direction.
