FIG. 7 is a front view of a state in which the door 3 of the drum-type washer-dryer 1 is opened and the accessory member 50 is attached to the entrance and exit 4 . In addition, FIG. 8 is a plan view of a state in which the door 3 of the drum-type washer-dryer 1 is opened and the accessory member 50 is attached to the entrance and exit 4 . Moreover, FIG. 9 is a longitudinal sectional view of the drum-type washer-dryer 1 along line IX-IX of FIG. 8 .

As shown in FIG. 7 , the drum-type washer-dryer 1 is in a state in which the door 3 is opened, and the accessory member 50 can be attached to the entrance and exit 4 formed in the front wall 2F of the box 2 . Furthermore, the drum-type washer-dryer 1 can perform a drying operation with the door 3 opened and the accessory member 50 attached.

The flow of air during the drying operation in this case is shown by the thick black arrow in Fig. 9 . 9 , when the blower fan 8 rotates, the air in the inner cylinder 6 flows into the circulation air path 22 from the many small holes in the rear surface wall 6B of the inner cylinder 6 and the air outlet of the rear surface wall 5B of the outer cylinder 5 . Then, while flowing through the circulation air path 22 , the air is dehumidified by the first heat exchanger 9 and heated by the second heat exchanger 10 . Then, the air passes through the outlet flow path 11 of the circulating air path 22 , passes through the air flow guide path 57 of the accessory member 50 , passes through the outflow port 55 , and is discharged to the space XF in front of the drum-type washer-dryer 1 through the ventilation guide 56 .

The air in the inner cylinder 6 passes through the circulation air duct 22 and is discharged to the front XF space. Therefore, the air pressure in the inner cylinder 6 decreases. Therefore, air in the space in which the drum-type washer-dryer 1 is disposed enters the inner cylinder 6 from the many small holes 54 formed in the cover portion 51 of the accessory member 50 . Then, the air that has entered the inner cylinder 6 is dehumidified and heated in the circulation air path 22 as described above, and is discharged to the front outside the machine through the outlet flow path 11 and the attachment member 50 .

In this way, the drum-type washer-dryer 1 dehumidifies the air in the installation space of the drum-type washer-dryer.

FIG. 10 is a flowchart for explaining the operating method of the drum-type washer-dryer 1 .

When the drum-type washer-dryer 1 is used to dehumidify the space in the installation space, the door 3 of the drum-type washer-dryer 1 is opened, and the accessory member 50 is attached to the entrance and exit 4 of the box 2 (step S1) .

Then, the indoor dehumidification button provided on the operation panel is pressed (step S2).

When the indoor dehumidification button is pressed, the control unit composed of, for example, a microcomputer of the drum-type washer-dryer 1 senses whether the accessory member 50 is attached (step S3). This sensing can be performed by whether the replacement lock pin 60 (see FIG. 6 ) of the accessory member 50 is engaged with the locking mechanism 43 (see FIG. 4 ) provided on the annular step 41 of the box 2 instead of the lock pin 35 of the door 3 . Sensing.

When it is determined that the accessory member 50 is not attached, the control unit displays an error indicating that the indoor dehumidification operation cannot be performed (step S4).

When the attachment of the accessory member 50 is sensed by the control unit, the operation time setting and the operation intensity setting can be performed on the operation panel (step S5). This setting can also be made by the user in advance. Then, after setting, the user presses the start button provided on the operation panel (step S6).

In response to the pressing of the start button, the control unit starts rotating the blower fan 8 (step S7), and starts operating the compressor 12 to start the heat pump cycle (step S8).

Then, the control unit continues the indoor dehumidification operation while detecting the temperature of the drying air flow discharged from the outlet flow path 11 (step S9).

If the temperature of the drying air flow discharged from the outlet flow path 11 exceeds 45° C. as an example, the compressor 12 is stopped to stop the heat pump unit (step S10 ).

Then, when the indoor dehumidification operation reaches the set time (step S11), the control unit stops the compressor 12 (step S12), stops the blower fan 8 (step S13), ends the indoor dehumidification operation, and integrates the drum washing and drying. Machine 1 automatically shuts down (step S14).
