[0006] According to the washing and drying machine configured as described above, after the laundry is put into the drum by the user through the opening of the outer box, the washing operation, the rinsing operation, and the dehydration are performed based on the operation content set by the user. At least one of the operation and the drying operation is performed.

[0007] In the drying operation described above, the drying system operates while the drum rotates alternately in the left and right directions while the dehydrated laundry is in the drum. As a result, the air heated by the heating mechanism is supplied into the drum through the hot air blowing unit and hits the laundry being stirred, so that the water impregnated in the laundry can be evaporated.

[0008] However, in the above conventional washing and drying machine, the drying system is located between the upper surface of the outer box and the outer upper part of the water tank. The temperature of the upper shell will rise. At this time, the user touches the upper outline of the outer box. And if the user feels uncomfortable, it will cause anxiety. For this reason, it is necessary to add a heat insulating material to the outer shell of the drying system or to add a heat insulating material below the upper surface of the outer box. However, there is a problem that the attachment of the heat insulating material causes an increase in manufacturing cost.

[0009] Further, since the drying system is arranged outside the water tank, the radiant heat of the outer shell of the drying system is hardly transmitted to the laundry in the drum. That is, the radiant heat of the outer shell of the drying system is wasteful because it does not contribute to the drying of the laundry. Therefore, there is a problem that the efficiency of drying the laundry with respect to the energy applied to the drying system is low.

The air blowing mechanism unit 200 is attached to the lower part of the rear surface of the water tank 3. The blower mechanism 200 includes a fan case 201, a fan 202 housed in the fan case 201, and a fan motor 203 that rotates the fan 202.

The fan case 201 is attached to the lower rear portion of the water tank 3 so that the space in the fan case 201 communicates with the space in the water tank 3. The fan case 201 is provided with a hole 204 through which the sheathed heater 301 can be passed. The hole 204 is an example of a third hole.

The fan 202 is directly connected to the rotating shaft of the fan motor 203. By rotating the fan 202 with the fan motor 203, the air in the water tank 3 can be directly sucked into the fan case 201.

The heating mechanism unit 300 is disposed between the lower part of the water tank 3 and the lower part of the drum 4. The heating mechanism section 300 includes a sheathed heater 301, a metal heater case 302 surrounding the heat generating section 311 of the sheathed heater 301, and a heater case support component 303 that supports the heater case 302 in the water tank 3.

[0058] The sheathed heater 301 can heat the air in the water tank 3, and can also heat the water in the water tank 3, washing water, and the like. Further, the heat generating portion 311 of the sheathed heater 301 is placed in the heater case 302 by passing the sheathed heater 301 through the hole 204 of the fan case 201. In addition, a metal heater flange 313 is provided integrally with the sheathed heater 301 on the terminal side 312 of the sheathed heater 301 (the side opposite to the heat generating portion 311), and the hole 204 of the fan case 201 is sealed. A heater packing 314 is provided. In addition The part 312 is an example of a mounting portion, the heater packing 314 is an example of packing, and the heater flange 313 is an example of a flange.

[0059] Most of the upper portion of the heater case 302 (the portion on the drum 4 side) is not covered with the heater case support component 303 and is exposed from the heater case support component 303. That is, most of the upper portion (the portion on the drum 4 side) of the heater case 302 faces the outer peripheral surface of the drum 4. On the other hand, most of the lower part of the heater case 302 is covered with the heater case support component 303. In addition, a protrusion 322 that protrudes toward the water tank 3 is provided at the lower part of the heater case 302. The convex portion 322 has an inclined surface 323 for preventing water from collecting in the convex portion 322. Specifically, the inclined surface 323 is formed so as to incline with respect to a horizontal plane during use and to have the rear part lowered from the front part. In addition, a heater support 321 that supports the sheathed heater 301 is provided on the inner wall of the heater case 302 in the vicinity of the convex portion 322. The heater support 321 guides the heat generating portion 311 of the sheathed heater 301 to a predetermined position in the heater case 302 when the sheathed heater 301 is passed through the hole 204. Needless to say, as described above, the inclined surface 323 is inclined with respect to the horizontal plane when the drum-type washing machine is completed. The heater support 321 is an example of a support part.

The heater case support component 303 is fixed only to the rear portion 32 of the water tank 3. The heater case support component 303 is made of a heat-resistant resin. A hole 331 for exposing the convex portion 322 of the heater case 302 is provided in the lower portion of the heater case support component 303. The hole 331 is an example of the first hole.

[0061] The hot air blowing part 400 is fixed only to the front part 31 of the water tank 3. Further, the rear end portion of the hot air blowing portion 400 is connected to the front end portion of the heater case 302. On the other hand, the front end of the hot air outlet 400 is located between the lower front part of the water tank 3 and the lower front part of the drum 4. The air blowing port 40 provided at the front end of the hot air blowing part 400 is located between the lower edge of the water tank opening 18 and the lower edge of the drum opening 26, and is connected to the drum opening 26. Facing (see Figure 2).

[0062] Further, a heat-resistant cushioning material 600 is disposed between the heater case 302 and the heater case support component 303 and between the heater case 302 and the hot air blowing part 400. The heat resistant cushioning material 600 is an example of a cushioning material. In addition, a hole 33 facing the hole 331 is provided in the lower part of the water tank 3. In this hole 33, an overtemperature preventing device 500 for controlling the temperature of the heater case 302 is passed! The end of the overheat prevention device 500 on the heater case 302 side is in contact with the convex portion 322 of the heater case 302. The hole 33 is an example of a second hole, and the overtemperature prevention device 500 is an example of a temperature control component.

[0064] According to the drum type washing machine having the above configuration, the heating mechanism 300 and the hot air blowing part 400 are located between the lower part of the water tub 3 and the drum 4, so that the heating mechanism 300 and the hot air blowing part 400 The radiant heat is blocked by the tank 3 and does not reach the outer box 1 directly. Therefore, since the outer box 1 can be prevented from becoming hot even without a heat insulating material, the user's unpleasant feeling and anxiety can be suppressed without causing an increase in manufacturing cost.

[0065] When drying the laundry in the drum 4, the drying system 6 is operated. When this drying system 6 is in operation, air circulates in the water tank 3 as shown by the arrows in FIG. More specifically, when the drying system 6 operates, the fan 202 of the air blowing mechanism unit 200 rotates, and the hot air generated by the sheath heater 301 blows out from the air blowing port 40 toward the lower part of the space in the drum 4. Thereby, the moisture of the laundry in the drum 4 evaporates. The moisture-containing air, that is, humid air, goes out of the drum 4 through the small holes 27 and is cooled by the heat exchanger 100 for dehumidification at the lower part of the space in the water tank 3. As a result, moisture contained in the humid air is condensed. That is, the humid air is dehumidified by the heat exchanger lOO for dehumidification to become dry air. This dry air is sent into the heater case 302 by the blower mechanism 200, heated again by the sheath heater 301, and then blown out from the blower opening 40 toward the lower part of the drum 4. That is, the warm air generated by the sheathed heater 301 is blown out from the air outlet 40 toward the lower part of the space in the drum 4.

[0066] When the laundry is dried in this manner, the heating mechanism unit 300 and the hot air blowing unit 400 are located between the water tub 3 and the drum 4, so that the heating mechanism unit 300 and the hot air blowing unit 400 are diffused. Heat can be kept in the tank 3. That is, the heat that dissipates the outer force of the heating mechanism section 300 and the hot air blowing section 400 can be used as the heat that contributes to the drying of the laundry in the drum 4. Therefore, the heat dissipation loss of the drying system 6 can be minimized, and the efficiency of drying the laundry can be increased. [0067] In addition, since the air blowing mechanism unit 200 is disposed outside the water tank 3, installation and maintenance of the air blowing mechanism unit 200 are simple.

[0068] Further, since the metal heater case 302 surrounds the heat generating portion 311 of the sheathed heater 301, even if lint adheres to the heat generating portion 311 of the sheathed heater 301 and burns, The heater case 3 02 can prevent waste fire from burning into the heater case support component 303 and the water tank 3. Therefore, the safety of the drum type washing machine can be improved.

It is possible to suppress rattling of the heater case 302, the heater case supporting component 303, and the hot air blowing part 400 due to vibration during dehydration of the object. Therefore, it is possible to prevent abnormal noise from being generated by the heater case 302, the heater case support component 303, and the hot air outlet 400.

[0077] Further, since the hot air blowing part 400 is fixed only to the front part 31 of the water tank 3, and the heater case support component 303 is fixed only to the rear part 32 of the water tank 3, the front part of the water tank 3 and the water tank 3 In combination with the rear part, the heater case 302 supported by the heater case support component 303 and the hot air blowing part 400 can be combined. Accordingly, assembly of the water tank 3 and the drying system 6 is facilitated, and the assemblability of the drum type washing machine of the present embodiment is high.

[0078] Further, by adopting a structure in which the sheathed heater 301 is passed through the hole 204 provided in the blower mechanism section 200, even if a malfunction occurs in the sheathed heater 301, the sheathed heater 301 having the malfunction is removed. Can be easily replaced. Therefore, the serviceability of the drum type washing machine of the present embodiment is high.

[0079] In the above embodiment, the drying system 6 is provided between the water tank 3 and the drum 4 below the plane including the central axis of the water tank 3 and including the horizontal axis orthogonal to the central axis. For example, the drying force between the tank 3 and the drum 4 is higher than the plane including the central axis of the water tank 3 and the horizontal axis perpendicular to the central axis. Place part of system 6 May be. Alternatively, a part of the drying system 6 is disposed between the aquarium 3 and the drum 4 on the left side of the plane including the central axis of the aquarium 3 and including the vertical axis perpendicular to the central axis.
