As described above, by housing the processing agent holding section 340 in the case section 320, the filter section 310 and the processing agent holding section 340 are integrated.

  In the fully automatic washer / dryer 1, a washing operation, a washing / drying operation, or a drying operation of various driving courses is performed. The washing operation is an operation for only washing, and the washing process, the intermediate dewatering process, the rinsing process, and the final dewatering process are sequentially executed. The washing / drying operation is an operation in which washing to drying are continuously performed, and the drying step is executed subsequent to the final dehydration step. The drying operation is an operation in which only drying is performed, and only the drying process is executed.

  In the washing process and the rinsing process, the pulsator 26 rotates rightward and leftward in a state where water is stored in the washing / dehydrating tank 24. The rotation of the pulsator 26 causes a water flow in the washing / dehydrating tub 24. In the washing step, the laundry is washed with the generated water flow and the detergent contained in the water. In the rinsing step, the generated water flow rinses the laundry.

  In the intermediate dehydration process and the final dehydration process, the laundry dehydration tub 24 and the pulsator 26 integrally rotate at high speed. The laundry is dehydrated by the action of the centrifugal force generated in the washing / dehydrating tank 24.

  In the drying step, the inside air circulation drying step is first performed, and then the outside air introducing drying step is performed. In the inside air circulation drying step, the opening 231a is closed by the flap 251 in the lower exhaust air passage 230 (see FIG. 8). As a result, exhaust cannot be performed through the lower exhaust air passage 230 and the upper exhaust air passage 240. The blower fan 120 and the heater 130 operate in the warm air generating unit 51. When the blower fan 120 operates and the blower 121 rotates, as shown by the arrow in FIG. 7, air is sucked into the casing 110 from the suction port 113, and wind is generated in the fan chamber 111. The generated wind flows through the discharge air passage 112, is heated by the heater 130, becomes warm air, and is discharged from the discharge port 114. The warm air discharged from the discharge port 114 is supplied into the outer tub 20 through the intake duct 71.

  The warm air supplied to the outer tub 20 flows through the washing / dehydrating tub 24. In the washing / dehydrating tank 24, the pulsator 26 rotates clockwise and counterclockwise at regular intervals. The laundry in the washing / dehydrating tub 24 comes into contact with the warm air flowing in the washing / dehydrating tub 24 while being stirred by the pulsator 26. The warm air that has flowed through the washing and dewatering tank 24 is discharged from the inside of the outer tank 20 through the exhaust duct 72, passes through the inlet 222, the filter chamber 220, and the intake air passage 210, and again as shown by the arrow in FIG. 7. It is sucked into the casing 110 through the suction port 113.

  In the inside air circulation drying step, since the exhaust air cannot be exhausted through the lower exhaust air passage 230 and the upper exhaust air passage 240, the outside air is hardly taken in through the outside air intake port 223, so that the space between the circulation air passage 50a and the outer tub 20 can be reduced. The warm air circulates in the air, which causes the temperature inside the washing / dehydrating tank 24 to rise rapidly.

  The warm air discharged from the outer tub 20 is mixed with foreign matter such as lint discharged from the laundry due to stirring by the pulsator 26 or the like. The warm air passes through the filter material 342 of the treatment agent holding portion 340 and the filter material 313 of the filter portion 310 in the filter unit 53 in the filter chamber 220, and the foreign matter contained in the hot air is captured by these filter materials 342 and 313. It

  When the temperature inside the washing / dehydrating tub 24 rises and the moisture evaporates from the laundry and the warm air contains a large amount of moisture, the process is switched to the outside air introduction drying step. The switching to the outside air introduction drying step may be performed based on the lapse of time after the drying step is started, or the temperature inside the outer tank 20 detected by the temperature sensor and the outer tank detected by the humidity sensor may be changed. It may be performed based on the humidity within 20.

  In the outside air introducing and drying step, the flap 251 is opened and the opening 231a is opened in the lower exhaust air passage 230, as shown by the broken line arrow in FIG. As a result, the air can be exhausted through the lower exhaust air passage 230 and the upper exhaust air passage 240, so that the outside air can be taken in from the outside air intake port 223. In this state, the blower fan 120 and the heater 130 operate. The outside air taken in from the outside air intake port 223 passes through the filter chamber 220 and flows into the intake air passage 210 while being mixed with the warm air taken in from the introduction port 222, and the warm air mixed with the outside air enters the casing 110. Is sucked in. At this time, the outside air passes through the filter material 342 of the treatment agent holding portion 340 and the filter material 313 of the filter portion 310 inside the filter chamber 220, and foreign matters such as dust contained in the outside air are captured by these filter materials 342 and 313. To be done.

  In the outside air introduction drying step, since the flow rate of the warm air supplied into the outer tub 20 increases as the outside air is taken in, a part of the warm air containing a large amount of water in the outer tub 20 is partially exhausted in the lower exhaust air passage. The air is discharged to the outside of the housing 10 through the 230 and the upper exhaust air passage 240. That is, as shown by the solid line arrow in FIG. 8, a part of the warm air in the outer tub 20 flowing through the circulation air passage 50 a is discharged from the internal exhaust port 115 and discharged into the lower exhaust air passage 230 through the introduction port 232. To be done. The warm air discharged into the lower exhaust air passage 230 sequentially flows through the lower exhaust air passage 230 and the upper exhaust air passage 240, and is discharged from the external exhaust port 241 to the outside of the housing 10.

  By performing the outside air introduction drying step in this manner, the water evaporated from the laundry is effectively discharged from the inside of the outer tub 20 to the outside of the housing 10, and the inside of the outer tub 20 is easily dehumidified, so that the laundry is washed. Drying is accelerated. Since a part of the warm air from the outer tub 20 flows through the circulation air passage 50a and is reheated by the heater 130, the temperature inside the outer tub 20 is continuously maintained high. When the outside air introduction drying step is completed, the drying step is completed.

  In the drying process, the warm air passing through the filter chamber 220 comes into contact with the treatment agent P held in the treatment agent holding unit 340.

  In the filter unit 53, a space is provided between the bottom surface of the treatment agent holding portion 340 and the bottom surface of the case portion 320. As a result, the wind introduced from the introduction port 222 spreads out in the space and easily spreads over a wide area of the storage section 343, so that it is possible to suppress intensive consumption of only the treatment agent P directly above the introduction port 222. It

  When the treatment agent P disappears or becomes difficult to release the component due to use, the user removes the filter unit 53 from the filter chamber 220, removes the treatment agent holding section 340 from the case section 320, and removes the treatment agent P. Replenish, replace, etc. At this time, the user can also clean the filter materials 313 and 342 together. The user can also replenish and replace the processing agent P when the filter unit 53 is removed from the filter chamber 220 for the purpose of cleaning the filter materials 313 and 342.

<Effects of the embodiment>
According to the present embodiment, the processing agent holding section 340 that holds the processing agent P capable of releasing a predetermined component and is housed in the filter chamber 220 in a state integrated with the filter section 310 is provided in the filter unit 53. Be prepared. Therefore, the user can easily replenish or replace the processing agent P by removing the filter unit 53 from the filter chamber 220.

  Further, according to the present embodiment, the treatment agent holding unit 340 can be separated from the filter unit 310 in the state of being taken out from the filter chamber 220. Therefore, the filter unit 310 does not interfere when the treatment agent holding unit 340 is supplemented with the treatment agent P, and the treatment agent holding unit 340 does not interfere when the filter unit 310 is cleaned. I won't.

  Furthermore, according to the present embodiment, since the ventilation port 341 of the treatment agent holding portion 340 is covered with the filter material 342, when the wind passes through the treatment agent holding portion 340, foreign matter contained in the wind is removed. It can be captured by the filter material 342. Therefore, the efficiency of capturing foreign matter in the filter unit 53 is improved.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and the like, and the embodiments of the present invention can be modified in various ways other than the above. is there.

  For example, in the above embodiment, the treatment agent holding unit 340 is configured to be separable from the filter unit 310. However, the treatment agent holding portion 340 may be integrally formed with the case portion 320 so that the treatment agent holding portion 340 cannot be separated from the filter portion 310.

  Further, in the above-described embodiment, the ventilation port 341 is formed on the bottom surface of the treatment agent holding portion 340 over almost the entire bottom surface, and the ventilation port 341 is covered with the filter material 342. However, for example, by configuring the ventilation port 341 with a large number of holes that are slightly smaller than the bead-shaped processing agent P, the processing agent holding portion 340 may not be provided with the filter material 342.

  Furthermore, in the above embodiment, the treatment agent P in the form of beads is held in the treatment agent holding portion 340 as it is. However, the treatment agent P in the form of beads may be put in a bag having air permeability and held by the treatment agent holding portion 340. The treatment agent P does not have to be in the form of beads, and may have any size and shape as long as it can be held by the treatment agent holding section 340.

  Further, in the above embodiment, when the treating agent P which is an antibacterial agent is used, a washing operation course may be provided in which the antibacterial step is performed after the final dehydration step. In this case, in the antibacterial process, the blower fan 120 is operated by the control unit 16 to circulate the air between the circulation air passage 50a and the outer tub 20. At this time, the wind may be warmed by operating the heater 130. In the antibacterial step, the antibacterial component mixed with the wind adheres to the inner wall surface of the circulation air passage 50a, the inner wall surface of the outer tub 20, and the inner and outer wall surfaces of the washing / dehydrating tub 24, and the wall surface is provided with an antifungal effect. It

  Further, in the above-described embodiment, an example in which the present invention is applied to the fully automatic washer / dryer 1 in which the clothes drying function is incorporated in a so-called spiral type washing machine is shown. However, the present invention can also be applied to a drum type washer / dryer in which a clothes washing function is mounted on a drum type washer having a horizontal shaft type drum arranged in the outer tub.
