  As shown in FIGS. 2 and 3, the drying system 6 includes a central axis of the water tank 3 and is provided below a plane including a horizontal axis perpendicular to the central axis. That is, the drying system 6 is installed in the lower part of the space in the outer box 1. Further, the drying system 6 includes a blower 31, a heating device 32, a dehumidifying heat exchanger 33 and a blower duct 39.

  The blower 31 is attached to the lower rear portion of the water tank 3. The blower 31 includes a fan case 34, a blade 35 accommodated in the fan case 34, and a fan motor 36 that rotationally drives the blade 35, and the air in the water tank 3 is placed in the fan case 34.

The fan case 34 is disposed so as to be connected to the water tank 3. The space in the fan case 34 communicates with the space in the water tank 3 and also communicates with the space in the heater case 37 and the air duct 39.

  The heating device 32 is disposed in the lower part of the space in the water tank 3. More specifically, the heating device 32 is disposed between the inner peripheral surface of the water tub 3 and the outer peripheral surface of the drum 4, and is located in a region immersed in the washing liquid in the water tub 3. In addition, the heating device 32 includes a heater case 37 and a sheathed heater 38 that is mostly accommodated in the heater case 37. The heater case 37 includes a metal main body and a heat-resistant resin frame that fixes the main body, and is connected to the air duct 39. The sheathed heater 38 can heat the air in the water tub 3 and can also heat water, washing water, and the like in the water tub 3 because it is disposed in a region immersed in the washing liquid in the water tub 3. The heater case 37 and the air duct 39 constitute an example of the air passage. The sheathed heater 38 is an example of an electric heater.

  The dehumidifying heat exchanger 33 is disposed in the lower part of the space in the water tank 3. More specifically, the dehumidifying heat exchanger 33 is disposed in a region immersed in the washing liquid between the inner peripheral surface of the water tub 3 and the outer peripheral surface of the drum 4.

  When the drying system 6 having the above configuration is operated, air circulates in the water tank 3 as indicated by arrows in FIG. More specifically, when the drying system 6 operates, the blades 35 of the blower 31 rotate, and the warm air generated by the sheath heater 38 blows out from the blower opening 40 toward the lower part of the space in the drum 4. Thereby, the water | moisture content of the laundry in the drum 4 evaporates. The moisture-containing air, that is, humid air, exits from the small hole 27 to the outside of the drum 4 and is cooled by the dehumidifying heat exchanger 33 in the lower part of the space in the water tank 3. Thereby, the moisture contained in the humid air is condensed. That is, the humid air is dehumidified by the dehumidifying heat exchanger 33 to become dry air. This dry air is sent into the heater case 37 by the blower 31, heated again by the sheathed heater 38, and then blown out from the blower opening 40 toward the lower part in the drum 4. That is, the warm air generated by the sheathed heater 38 blows out from the blower opening 40 toward the lower part of the space in the drum 4.

  According to the washing and drying machine having the above configuration, the drying system 6 including the sheathed heater 38 is provided below the surface including the central axis of the water tank 3 and including the horizontal axis perpendicular to the central axis. Therefore, the position of the water tank 3 can be increased. Accordingly, it is possible to increase the height of the outer box opening 11 serving as a laundry outlet. Therefore, the user can easily put in and out the laundry without first leaving, so that the laundry can be put in and out easily.

  Moreover, although the motor 5 is attached to the rear part of the water tank 3, since the drying system 6 including the sheathed heater 38 is provided below the surface, the center of gravity of the water tank 3 can be prevented from being biased. .

  Moreover, since the center axis | shaft of the water tank 3 inclines with respect to a horizontal surface so that the rear part of the water tank 3 may fall from the front part of the water tank 3, a space arises between the rear surface lower part of the water tank 3 and the outer case 1. FIG. Therefore, the blower 31 can be attached to the lower rear portion of the water tank 3 using the space.

  Further, since the heating device 32 is disposed in the lower part of the space in the water tank 3, the heat of the heating device 32 is transmitted to the upper part of the outer box 1 through the water tank 3 and the drum 4. Therefore, since the upper part of the outer box 1 does not become hot by the heat of the heating device 32, it is not necessary to provide a heat insulating material between the upper part of the outer box 1 and the heating device 32. As a result, the manufacturing cost of the drum 4-type washing machine can be reduced by the heat insulating material.

  In addition, since the heater case 37 is disposed between the water tank 3 and the drum 4, the heat of the heater case 37 can be efficiently transferred into the water tank 3. Therefore, the heat dissipation loss of the heater case 37 can be reduced.

  Further, since the heater case 37 is disposed between the water tank 3 and the drum 4, the heat of the heater case 37 is transmitted to the upper portion of the outer box 1 through the water tank 3 and the drum 4. Therefore, since the upper part of the outer box 1 does not become heated by the heat of the heater case 37, it is not necessary to provide a heat insulating material between the upper part of the outer box 1 and the heater case 37. As a result, the manufacturing cost of the drum type washing machine can be reduced by the heat insulating material.

  Further, since there is a gap between the heater case 37 and the water tank 3, it is possible to prevent the water tank 3 from becoming excessively hot due to the heat of the heater case 37.

  Moreover, since the frame of the heater case 37 is made of a heat resistant resin, safety and assemblability can be improved.

  Further, since the frame of the heater case 37 is made of a heat resistant resin, it is not necessary to use a flame retardant as the material of the water tank 3. Therefore, the manufacturing cost of the drum type washing machine can be reduced.

  Further, since the air blower 31 directly sucks the air in the water tank 3 into the fan case 34, a duct for connecting the air blower 31 and the water tank 3 becomes unnecessary. Therefore, the manufacturing cost of the drum type washing machine can be reduced, and the drum type washing machine can be miniaturized.

  Further, since the dehumidifying heat exchanger 33 is disposed in a region immersed in the washing liquid in the water tub 3, lint and the like adhering to the dehumidifying heat exchanger 33 can be washed away with the washing liquid in the water tub 3.

  Further, since the space in the fan case 34 and the space in the water tub 3 communicate with each other, the lint attached to the inner wall of the fan case 34 and the blades 35 can be washed away with the washing liquid in the water tub 3.

  Moreover, since the water tank opening 18 is eccentric to the top surface side of the outer box with respect to the drum opening 26, the position of the outer box opening 11 can be made higher. Therefore, the user can more easily take in and out the laundry.

  Further, since the air blowing port 40 is provided between the lower edge of the water tank opening 18 and the lower edge of the drum opening 26, the warm air blown from the air blowing port 40 is applied to the laundry in the lower part in the drum 4. Direct hit. As a result, since the warm air efficiently hits the laundry, the laundry is dried in a short time. That is, the laundry drying time can be shortened.

  Moreover, since the sheathed heater 38 is used for both the generation of hot air and the generation of hot water, the number of parts can be reduced.

  In the embodiment described above, the entire drying system 6 is provided below the plane including the central axis of the water tank 3 and including the horizontal axis orthogonal to the central axis, but passes through the central axis of the water tank 3. A part of the drying system 6 may be provided below the surface.
