- the heating device 94 includes a drying heater (not shown), and is disposed substantially at the center of the upper part of the water tank 8 in the front-rear direction.
- a hot air return port 95 is formed in the rear end plate portion 13 of the water tank 8.
- One end of the heat exchanger 92 is connected to the hot air return port 95.
- the other end of the heat exchanger 92 is connected to the suction side of the fan device 93 via a bellows-like connecting duct 96.
- the discharge side of the fan device 93 is connected to the heating device 94 by a duct 97.
- a hot air discharge port 98 is formed in the port 20.
- the hot air discharge port 98 and the heating device 94 are connected by a duct 99.
- the rotating tub 24 functions as a drying drum in addition to a washing tub and a dehydrating tub. That is, at the time of the drying operation, the drying device 93 is driven at the same time as the rotary tank 24 is rotated, and the drying heater of the heating device 94 generates heat. As a result, as shown by the arrow A in FIG. 12, the air in the rotary tank 24 is sucked into the heat exchanger 92 from the hot air return port 95. The air sucked into the heat exchanger 92 continues After passing through the connecting duct 96, the fan device 93, the duct 97, the heating device 94, and the duct 99, it is returned from the hot air outlet 98 into the water tank 8, that is, into the rotary tank 24. By this circulation, the air in the rotary tub 24 is warmed and dehumidified, and the laundry in the rotary tub 24 is dried.
- the heat exchanger 92 is provided at the rear of the water tank 8, and when the water tank 8 swings and tilts backward, the heat exchanger 3 Prior to 3, the heat exchanger 92 is configured to contact the rear wall 4 of the outer box 1. Therefore, in this embodiment, the heat exchanger 92 is Functions as
- the motor 33 may be configured so that substantially the entirety thereof is located in the concave portion 31.
- the back plate 6 may be configured on a substantially flat surface.
- a concave portion may be formed in the rear surface of the water tank 8, and the motor may be positioned in the concave portion.
- the drum-type washing machine according to the present invention is useful as a washing machine that can be installed in a narrow place, and is particularly suitable for being installed in a place where the length dimension in the front-rear direction is limited. I have.
