This required time is determined in advance through experiments or the like and is stored in the memory of the control unit 40. In this way, the interior of the container 20 becomes empty, and therefore, it is possible to prevent mold and other bacteria from multiplying in the container 20 due to water remaining in the container 20 during the period from the end of the drying operation to the start of the next drying operation.
  • the foreign matter guided to the outflow path 8 along with the drainage of the container 20 is captured by the drainage filter 9.
  • the drainage filter 9 may be omitted. In this case, the foreign matter guided to the outflow path 8 passes through the outflow path 8 and is directly discharged out of the machine.
  • the water filter 7 having the internal space 20A allows the air flowing from the washing tub 5 to the outlet 30D for circulation to pass through the water in the internal space 20A of the container 20, Then, the foreign matter is captured from the air and stored in the internal space 20A. In this case, as long as the water in the internal space 20A is drained, the foreign matter stored in the internal space 20A is also discharged together with the water, so the water filter 7 can be easily maintained. Therefore, it is possible to improve the usability for the drying operation.
  • the inner space 20A of the water filter 7 constitutes the bottom 3J of the outer tube 3, and therefore the arrangement space of the outer tube 3 and the space around it can be effectively used to increase the size of the inner space 20A, that is, the water filter 7.
  • the water filter 7 can be matched to the space S. Large-scale.
  • the arrangement space of the water filter 7 is restricted, and the internal space 20A becomes smaller, which becomes the resistance of the air, so that the air volume in the water filter 7 is reduced Loss may increase.
  • the water filter 7 is integrally formed on the bottom 3J of the outer cylinder 3. Therefore, by increasing the size of the bottom 3J of the outer cylinder 3 for the water filter 7, the water filter 7 can be increased in size. In addition, the number of parts can also be reduced.
  • the water filter 7 is integrated with the outer tube 3, so that it can vibrate integrally with the outer tube 3 during the operation of the washer-dryer 1, and therefore can be utilized as the support member 17 of the vibration absorbing structure of the outer tube 3 to absorb Vibration of the water filter 7. As a result, the number of parts can be further reduced.
  • Fig. 2 is a perspective view of a main part of the washer-dryer 1 of a modified example.
  • the same parts as the parts described so far are denoted by the same reference numerals, and the description of the parts is omitted.
  • the container 20 of the water filter 7 is provided as a different component from the outer cylinder 3, and is assembled to the bottom 3J of the outer cylinder 3 in a manner of later mounting.
  • the bottom part 3J is provided with the recessed part 3M recessed to the lower side Z2, and the container 20 is accommodated in the recessed part 3M.
  • the container 20 has a top wall 50 connected to the upper end of the side wall 22 and covering the internal space 20A from the upper side Z1, and a through hole 50A communicating with the internal space 20A is formed in the top wall 50.
  • the water in the outer cylinder 3 passes through the through hole 50A and flows into the internal space 20A.
  • the circulating air flows into the container 20 from the washing tub 5 through the through hole 50A.
  • the circumferential wall 3A of the outer cylinder 3 may be divided back and forth like a modified example.
  • the inner tube 4 may be arranged such that the axis J is inclined in the horizontal direction.
  • the integrated washer-dryer 1 may also be a vertical integrated washer-dryer whose axis J extends longitudinally.
  • the water supply path 6 and the water supply valve 19 can be used not only for the water supply to the washing tub 5 but also for the water supply to the water filter 7.
  • the outflow path 8 and the drain valve 25 can be used not only for the drainage of the washing tub 5 but also for the drainage of the water filter 7. Therefore, the number of parts can be reduced.
  • the washer-dryer 1 may also include: an inflow path (not shown) that branches from the water supply path 6 to supply water to the container 20 of the water filter 7; and an inflow valve (not shown) (Illustration), to open and close the inflow path.
  • the washer-dryer 1 includes a drainage path (not shown) extending from the bottom 3J of the outer cylinder 3 and leading out of the machine, and a drainage filter 9 and a drainage valve 25 are arranged in the middle of the drainage path, derived from The outflow path 8 of the water filter 7 merges with this drainage path.
  • an outflow valve (not shown) that opens and closes the outflow path 8 and the drain valve 25 may be provided separately. That is, a dedicated inflow path, inflow valve, outflow path 8, and outflow valve for the water filter 7 can be provided.
  • the washer-dryer 1 may further include: an overflow path (not shown) for forcibly draining the water in the washing tub 5 that exceeds a prescribed water level.
  • the overflow path connects the outer cylinder 3 with the downstream area of the outflow path 8 that is closer to the outside of the machine than the drain filter 9.
  • the overflow path can be used to discharge the water in the water filter 7 to the outside of the machine.
  • a dedicated overflow channel for the water filter 7 may be additionally provided.
