Moreover, there is little leakage of warm air with a rotation hinge, and it can supply to a washing tub through a cover.

  Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a washing / drying machine showing an embodiment of the present invention. The outer tub 2 contained in the outer frame 1 is supported from four upper corners of the outer frame 1 by four suspension rods 4. The suspension bar 4 is provided with an oscillating spring 5 so as not to transmit vibration during washing or dehydration to the outer frame. A washing tub 3 is provided inside the outer tub 2, and a stirring blade 6 is provided at the center bottom of the washing tub 3 to stir the laundry and apply mechanical force to the laundry to remove the dirt adhering to the laundry. Is provided.

  In addition, a fluid balancer 7 is provided on the upper part of the washing tub 3 to improve the vibration proofing property when the washing tub rotates at high speed to dehydrate moisture contained in the laundry by centrifugal force. . Also, a plurality of dewatering holes 3a are provided for the laundry tub 3 to rotate at high speed to dewater the moisture contained in the laundry by centrifugal force.

  In these operations, first, water required for washing is supplied into the washing tub 3 through the water supply hose 11 by operation of the water supply electromagnetic valve 10 by operation of the control base 9 provided on the front surface of the top cover 8. As shown, a water inlet 12 is provided. The water required for washing is controlled by detecting a change in air pressure of the air trap 13 provided on the bottom side wall of the outer tub 1 by the water level sensor 15 via the PS tube 14.

  When a predetermined amount of washing water is supplied to the laundry, the motor 16 provided at the bottom of the outer tub 2 is driven, and at the time of washing, a switching operation of a clutch (not shown) provided in the motor 16 is performed. The agitation blade 6 in the center of the bottom of the washing tub 3 is automatically reversed and operates periodically to apply mechanical force to the laundry for washing. When washing and rinsing are automatically finished by the microcomputer built in the control kiban 9, the drain valve 19 connected via the internal drain hose 20 is opened and closed, and the drain hose 18 is used for washing water, rinse water and dehydration. Wash water is drained outside the machine.

  When the final rinsing is completed, in the final dehydration, as described above, the washing tub 3 is rotated in one direction at a high speed, the water contained in the laundry is removed from the dehydration hole 3a by centrifugal force, and a series of washing courses is completed.

  When the course until drying is selected when the washing course is completed, the process proceeds to the drying process as it is. When only the washing course is selected, the process is terminated as it is.

  Next, the drying after the washing course will be described. First, the structure of the drying unit will be described. An outer tank cover 25 that covers the upper surface portion is provided on the upper part of the outer tank 2. A bellows 27, which is an elastic body, is attached to the outer tank cover 25 on the circumference by a plurality of fixing screws 26. The bellows 27 is fixed to a rib 28 formed integrally with the top cover 8 on the inner side of the top cover 8 so as not to drop off by a washer 29.

  When the laundry is dried after the final dehydration, the drain valve 19 is closed and the washing tub 3 is rotated at a low speed of about 30 times / minute or less, while the blade 6 is rotated forward and backward occasionally to move the laundry. The unit 22 is energized and warm air is blown by the blower fan 21. The air in the washing tub 3 is opened and closed when the laundry provided on the upper surface portion of the top cover 8 is thrown in while circulating hot air in the direction of the arrow in the condensation passage 23 from the internal drain hose 20 through the connection hose 24. The hot air is guided to the air passage 37 of the lid 17 to be blown, and the hot air is directly blown into the washing tub as shown by the arrow from the hot air discharge portion 30 provided in the lid 17.

  When the warm air is blown to the laundry, the moisture of the laundry evaporates with heat as time passes and becomes hot air with high humidity and passes through the condensation passage 23. In the condensing passage 23, in order to condense hot air with high humidity and increase the drying efficiency, about 3 L of cold water is constantly sprayed in the washing tub 3 to increase the condensing efficiency.

  Here, when assembling the washing and drying machine, it becomes necessary to fix the bellows 27 and the top cover 8 when the top cover 8 is assembled. Since the rear side is not visible when assembled from the front side, the bellows 27 can be securely fixed to the top cover 8 by setting the washer 29 on the bellows 27 in advance and inserting it into the top cover 8 and then tightening the washer 29 on the front side.

And do laundry. After washing S02 ends, the process proceeds to draining step S03 for draining the washing water. In the draining step S03, the drain valve 19 is opened and the dirty detergent liquid is drained from the drain hose 18 outside the washing machine. When the drainage S03 is completed, the detergent contained in the laundry is dehydrated S04 by centrifugal force from the dewatering hole 8 by the high speed rotation of the washing tub 3.

  Next, after dehydration is completed, clean water for rinsing the laundry is supplied. As for water supply, clean water for rinsing is supplied into the washing tub 3 by the same operation as the water supply S01 at the time of washing. After the fresh water necessary for rinsing is supplied, the process proceeds to the rinsing step S05 and rinsing is performed. The rinsing step S05 is performed twice (rinsing 2) by the same operation, and then the drainage S03 is performed and the process proceeds to the final dehydration S06 step. The final dehydration step S06 is operated under the same control as the dehydration step S04 in the middle of the process, but in the final dehydration step, the dehydration time is extended and the dehydration speed is increased to sufficiently dehydrate the laundry water. Control is performed and the laundry course ends.

  In the case of the washing / drying course that automatically proceeds to drying, when the final dehydration S06 is completed, the process proceeds automatically to the drying step S07. However, the laundry that is not desired to be dried is taken out and only the laundry that is desired to be dried is placed in the washing tub 3.
