Description

  The present invention relates to a washing and drying machine.

  Conventionally, as a washing and drying machine, there is one disclosed in JP 2000-342880 A (Patent Document 1). This washing / drying machine is disposed between an outer box, a water tank disposed in the outer box, a drum disposed in the water tank for containing laundry, and an upper surface of the outer box and an outer upper part of the water tank.

A heater packing 314 is provided. The portion 312 is an example of an attachment portion, the heater packing 314 is an example of packing, and the heater flange 313 is an example of a flange.

  Most of the upper part (the part on the drum 4 side) of the heater case 302 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 part (the part 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 a heater case support component 303. In addition, a protrusion 322 that protrudes toward the water tank 3 is provided at the lower portion 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 be inclined with respect to the horizontal plane when used and the rear portion is lowered from the front portion. 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 inserted into the hole 204. Needless to say, the inclined surface 323 is inclined with respect to the horizontal plane as described above 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 a first hole.

  The hot air blowing part 400 is fixed only to the front part 31 of the water tank 3. Further, the rear end of the hot air blowing section 400 is connected to the front end of the heater case 302. On the other hand, the front end of the hot air blowing section 400 is located between the lower front part of the water tank 3 and the lower front part of the drum 4. The blower opening 40 provided at the front end of the hot air outlet 400 is located between the lower edge of the water tank opening 18 and the lower edge of the drum opening 26 and faces the drum opening 26. (Refer to FIG. 2).

  In addition, 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 outlet 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. An overtemperature preventing device 500 for controlling the temperature of the heater case 302 is inserted into the hole 33. An 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 over-temperature prevention device 500 is an example of a temperature control component.

  According to the drum type washing machine having the above configuration, since the heating mechanism unit 300 and the hot air blowing unit 400 are between the lower portion of the water tank 3 and the drum 4, the radiant heat of the heating mechanism unit 300 and the hot air blowing unit 400 is It is blocked by the water 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 discomfort and anxiety can be suppressed without causing an increase in manufacturing cost.

  Further, when the laundry in the drum 4 is dried, the drying system 6 is operated. When the drying system 6 is operated, air circulates in the water tank 3 as shown by arrows in FIG. More specifically, when the drying system 6 operates, the fan 202 of the air blowing mechanism unit 200 rotates, and the warm 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 water | moisture content of the laundry in the drum 4 evaporates. The moisture-containing air, that is, humid air, exits from the small holes 27 to the outside of the drum 4 and is cooled by the dehumidifying heat exchanger 100 at the lower part of the space in the water tank 3. Thereby, the moisture contained in the humid air is condensed. That is, the wet air is dehumidified by the heat exchanger 100 for dehumidification to become dry air. The dry air is sent into the heater case 302 by the blower mechanism 200, heated again by the sheathed heater 301, 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 301 blows out from the air outlet 40 toward the lower part of the space in the drum 4.

  Thus, when the laundry is dried, 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 heat dissipated by the heating mechanism unit 300 and the hot air blowing unit 400 is dissipated. It can be kept in the water tank 3. That is, the heat dissipated from the outline of the heating mechanism unit 300 and the hot air blowing unit 400 can be used as heat contributing 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.

  Moreover, since the ventilation mechanism part 200 is arrange | positioned out of the water tank 3, installation and maintenance of the ventilation mechanism part 200 are easy.

  Further, since the metal heater case 302 surrounds the heat generating part 311 of the sheathed heater 301, even if lint adheres to the heat generating part of the sheathed heater 301 and burns, the waste of the lint is heated. It is possible to prevent the heater case 302 from burning to the support component 303 or the water tank 3. Therefore, the safety of the drum type washing machine can be enhanced.

  In addition, since the heater case 302 does not contact the water tank 3, the influence of heat received by the water tank 3 from the heater case 302 can be reduced. That is, the amount of heat received by the water tank 3 from the heater case 302 can be reduced. Therefore, since the thermal deformation of the water tank 3 can be prevented, the safety of the drum type washing machine can be further enhanced.

  Further, most of the upper portion of the heater case 302 not covered with the heater case support component 303 faces the outer peripheral surface of the drum 4, so that the radiant heat outside the heater case 302 can be efficiently transmitted to the drum 4. it can.

  Further, since most of the lower portion of the heater case 302 is covered with the heater case support component 303, the radiant heat from the lower portion of the heater case 302 toward the water tank 3 can be blocked by the heater case support component 303. That is, the lower part of the heater case 302 and the water tank 3 can be thermally insulated by the heater case support component 303. Therefore, the amount of heat received by the water tank 3 from the heater case 302 can be further reduced.

  In addition, since the overheat prevention device 500 for controlling the temperature of the heater case 302 is in contact with the heater case 302, the temperature rise of the heater case 302 can be sensitively detected by the overheat prevention device 500. Therefore, the abnormal temperature rise of the heater case 302 can be quickly detected by the overheat prevention device 500, and the thermal influence from the heater case 302 to the peripheral components can be minimized.

  Further, since the convex portion 322 of the heater case 302 protrudes from the hole 331 of the heater case support component 303, it is easy to make the overheat prevention device 500 contact the heater case 302.

  In addition, since the inclined surface 323 of the convex portion 322 is formed so as to be inclined with respect to the horizontal plane and the rear portion is lower than the front portion, for example, even if water enters the heater case 302 when the laundry is dehydrated, the laundry During the drying, water does not accumulate in the convex portion 322. Therefore, the abnormal temperature rise of the heater case 302 can be accurately and immediately detected by the overheat prevention device 500.

  Further, since the 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 portion 400, the heat of the heater case 302 is heated by the heater. It is not transmitted directly to the case support component 303 and the hot air outlet 400. Therefore, the amount of heat received from the heater case 302 by the heater case support component 303 and the hot air outlet 400 is small, and thermal deformation of the heater case support component 303 and the hot air outlet 400 can be prevented.
