5 is a control block diagram of a first embodiment of a combined-use washing machine according to the present invention, and FIG. 6 is a flowchart illustrating a control method of the first embodiment of a combined-use washing machine according to the present invention.                     

First, when the laundry (m) is introduced into the drum 70, the door 52 is closed, and a dry washing machine is operated. In the lower portion of the tub 60, the water supply device 63 The water containing the detergent to be supplied is contained, the lower portion of the drum 70 is immersed in the water containing the detergent, the laundry (m) in the drum 70 is the through hole 74 of the drum 70 It is soaked in water containing detergent introduced through.

In addition, when the controller 53 drives the drum motor 72, the drum 70 is rotated, and the laundry object m contained in the drum 70 is moved upward by the lifter 75. When it is lifted up and free-falls, the time when it is buried by the action of detergent and water is dropped, the contaminated water in the tub 60 is drained to the outside of the casing 50 through the drainage device 64 to end the washing stroke. (S1)

The combined-use washing machine has a rinsing stroke for rinsing the remaining foam in the laundry (m) after the washing stroke as described above, and clean water is supplied through the water supply device 63 to be contained in the tub 60. The lower part of the drum 70 is submerged in clean water, and the laundry m in the drum 70 is soaked in clean water through the through hole 74 of the drum 70.

In addition, when the controller 53 drives the drum motor 72, the drum 70 is rotated, and the laundry object m contained in the drum 70 is moved upward by the lifter 75. The foam is rinsed by the clean water while being raised and free-falled, and the contaminated water containing the foam is drained to the outside through the drainage device 64 and the rinsing stroke is completed.                     

The drying combined washing machine performs a dehydration stroke for draining the laundry object m after the rinsing stroke as described above. When the controller 53 drives the drum motor 72 at a high speed, the drum 70 ) Is rotated at a high speed, the laundry (m) in the drum (70) is dehydrated while centrifugally rotated, the water dehydrated in the laundry (m) tub 60 through the hand 74 of the drum (70) Drained to the outside through the drainage device 64, and the dehydration stroke is completed. (S3, S4)

The drying combined washing machine performs a drying stroke in which moisture remaining in the laundry object m is dried by dehumidifying air after the above dehydration stroke is performed.

In the drying stroke, the drum 70 is rotated to lift and drop the dried object m, and the air in the tub 60 circulates through the circulation passage 80 and the tub 60. Air passing through the flow path 80 is dehumidified by the evaporator 130 and then supplied into the tub 60 to dry the laundry object m.

That is, the controller 53 turns on the drum motor 72 so that the drum 70 rotates, turns on the blower motor 91 so that the blowing fan 90 rotates, and the evaporator 130 The compressor 100 is turned on to dehumidify the circulating air. (S5, S6, S7)

The low temperature and low pressure gas refrigerant is circulated back to the compressor to form a refrigeration cycle.

In addition, when the blowing fan 90 rotates, the air in the tub 60 is blown into the first circulation duct 82 through the front circulation hole 65a, and passes through the evaporator 130 and has a low temperature and low pressure. Heat is lost to the liquid refrigerant, and the moisture in the air is condensed and dehumidified to change to low humidity air. The low-humidity air is heat-exchanged with a high-temperature, high-pressure gas refrigerant while passing through the condenser 110, and passes through the second circulation duct 84, and then passes through the rear circulation hole 60a of the tub 60. It is blown inside.

The low humidity air blown into the tub 60 is in contact with the washing object m flowing into the drum 70 through the through hole 74 of the drum 70 and falling. ) To dry.

At this time, the air in contact with the laundry (m) is changed to humid air, and is blown to the front side of the tub 60 and the drum 70 to open the front blowing hole (65a) and the first circulation duct 82 After passing in turn it is circulated to the evaporator (130).                     

Then, the humid air circulated to the evaporator 130 is a dehumidification by the evaporator 130, the temperature rise by the condenser 110 and the drying of the laundry (m) is repeated while the tub 60 and the circulation passage Circulate 80.

On the other hand, the combined-use washing machine is stopped after the drum 70 and the blower fan 90 are rotated for a set time, the compressor 100 is driven for a set time and stopped to stop the drying stroke. 6, the drum 70 and the blower fan 90 may be stopped and the compressor 100 may be turned off, depending on the degree of dryness of the circulating air.

That is, the dryness detection sensor 160 detects the dryness of the circulating air while the laundry to be m dried and outputs a signal according to the dryness to the controller 53, and the controller 53. Compares the detected dryness with the set dryness in the dryness. (S8)

In addition, the controller 53 continuously rotates the drum 70 and the blowing fan 90 until the sensed dryness reaches the set dryness, and keeps the compressor 100 on and detects the dryness. When the dried level reaches the set dryness level, the drum 70 and the blowing fan 90 are stopped, and the compressor 100 is turned off to complete the drying process. (S9)
