(See FIG. 8 (b)), it is positioned in the spaces 313h and 313h, respectively, and is locked to the locking portions 313g and 313g, respectively.

  As a result, the filter member 35 is held in the storage chamber 311.

  As shown in FIG. 5, the blower unit 40 includes a driving fan motor 41, a fan (not shown), and a fan case 42. The fan case 42 incorporates a heater 45 (see FIG. 3), and air sent from the fan is heated by the heater 45. The discharge port 43 of the blower unit 40 is connected to the hot air duct 50 as shown in FIG. As shown in FIG. 3, the hot air duct 50 is connected to a hot air outlet 4h provided in the outer tub cover 4d via a rubber bellows pipe 52 and a bellows pipe joint 53.

  In the present embodiment, the area of the hot air outlet 4h is made smaller than the air passage area of the drying duct 20, the hot air duct 50, the drying filter device 30, and the like, and the fan motor 41 is rotated at a high speed to generate high-pressure air. Is generated. As a result, high-speed wind is blown into the rotary drum 3 from the hot air outlet 4h, and this high-speed wind is blown to the clothing, so that wrinkles generated in the clothing can be stretched by the wind force. Here, the high-speed wind is, for example, 50 m / s or more.

  Further, since the blower unit 40 is provided on the upper right side in the housing 1, the hot air outlet 4h is provided at an upper right position of the outer tub cover 4d so that the distance to the hot air outlet 4h is as short as possible. is there.

  As a result, an increase in pressure loss can be prevented, and high-speed wind can be efficiently blown onto clothing.

  A temperature sensor (not shown) is provided in front of the drain port 4e (see FIG. 3), the intake port (not shown) of the blower unit 40, and the hot air outlet 4h.

  Next, the air flow during the drying operation will be described.

When the air blowing unit 40 is operated and the heater 45 is energized, high-speed hot air is blown into the rotary drum 3 from the hot air outlet 4h. In the rotary drum 3, high-speed hot air hits wet clothing and warms the clothing to evaporate moisture from the clothing. During the drying operation, the rotary drum 3 is rotated forward and backward, so that the clothes are lifted up to the vicinity of the hot air outlet 4h by the lifter 3e, and high-speed wind is applied to the clothes. At this time, since the distance between the warm air outlet 4h and the clothing is the shortest, the wrinkles of the clothing can be stretched with a high-speed wind.
The air that has become hot and humid flows into the outer tub 4 through the through hole in the peripheral wall of the rotating drum 3 and is sucked into the drying duct 20 from the air inlet 4f. In the drying duct 20, air flows from bottom to top. Cooling water from the water cooling and dehumidifying mechanism flows down on the wall surface of the drying duct 20, and the hot and humid air is cooled and dehumidified by coming into contact with the cooling water to be dried low-temperature air and sent to the drying filter device 30.

  In the dry filter device 30, air flows into the filter housing 31 through the inflow duct 320 and flows into the collection unit 351 from the rear side of the filter member 35. In the collection part 351, the air that has flowed in substantially straight toward the front part 352, hits the wall 352 a of the front part 352, and then passes through the filter 355 b of the right side part 355 to the right part 315 of the filter housing 31. Flowing. At this time, foreign matter such as yarn waste contained in the air is collected by the filter 355b of the side surface portion 355.

  At this time, since the air hitting the wall body 352a of the front surface portion 352 flows toward the right side surface portion 355, foreign matters such as yarn waste are gradually collected by the filter 355b from the side close to the front surface portion 352. Here, even in the state where the rear side of the filter member 35 is covered with the wall body 352a, the air in the collecting portion 351 flows out through the filter 355b of the right side surface portion 355, so that no clogging occurs immediately. It is possible to collect a lot of foreign matters such as yarn waste.

  When the dry filter device 30 is cleaned, the lid 350a of the filter member 35 is pushed in, the finger is put on the inside of the top plate 350, and the filter member 35 is taken out upward. At this time, if dust such as lint adheres to the filter 315a of the storage chamber 311, this is also cleaned.

  According to the drum type washing / drying machine of the present embodiment described above, the air sucked from the suction port 4f on the rear surface side of the rotary drum 3 flows into the inflow duct of the drying filter device 30 through the drying path R (drying duct 20). It is introduced from 320 and flows into the blower unit 40 from the outflow duct 330 on the side surface through the filter member 35. Then, the air blown out by the blower unit 40 is sent to the front side of the rotary drum 3 through the drying path R (the blower duct 50 and the like), and blown into the rotary drum 3 through the outlet 4h. That is, dry air circulates through the drying path R provided from the rear side to the front side of the rotary drum 3, and foreign matter such as lint from the air by the drying filter device 30 during the circulation. Therefore, the drying path R including the drying filter device 30 and the blower unit 40 can be set simply and shortly.

  Therefore, a drum-type washing and drying machine that can shorten the drying path R, suppress heat loss, and achieve energy saving (high efficiency) is obtained.

  The filter member 35 is provided with a filter 355b as a first filter, and the storage chamber 311 is provided with a filter 315a as a second filter. The foreign matter is preferably collected, and the flowing air can be suitably cleaned.

  The dry filter device 30 is installed on the rear side of the upper portion of the housing 1 and is provided so that the filter member 35 can be removed from the upper surface cover 1e. Therefore, the filter member 35 is pulled out upward during cleaning. It can be removed and easy to clean. Moreover, since the filter 315a of the storage chamber 311 can be easily exposed by removing, the cleaning operation in the storage chamber 311 can be easily performed.

  Since the filter 315a of the storage chamber 311 is provided on the right side 315, it is possible to visually check the adhesion state of foreign matters such as lint from the front side of the housing 1, and easily determine whether cleaning is necessary. can do.
