  • the first discharging valve 176 may be opened when the processing apparatus 100 operates, and may be closed when the processing apparatus 100 stops operating. That is, when the steam supplying device 140 or the dry air supplying device 150 operates, the first discharging valve 176 may be opened so that condensed fluid may be essentially continuously discharged from the inner case 120 to the storage unit 171. On the other hand, when the steam supplying device 140 or the dry air supplying device 150 stops operating, the first discharging valve 176 may be closed to block the first discharging channel 174 and prevent any moisture and odors generated by the fluid collected in the storage unit 171 from flowing backward into the processing space 125.
  • the second discharging valve 177 may be closed when the processing apparatus 100 operates, and may be opened when the processing apparatus 100 stops operating. That is, when the steam supplying device 140 or the dry air supplying device 150 operates, the second discharging valve 177 may be closed to prevent the fluid in the steam housing 142 from leaking out of the steam housing 142 and into the storage unit 171. On the other hand, when the steam supplying device 140 or the dry air supplying device 150 stops operating, the second discharging valve 177 may be opened so that any fluid remaining in the steam housing 142 may be discharged to the storage unit 171. The second discharging valve 177 may be closed again when a pre-set open time for the second discharging valve 177 is reached while the processing apparatus 100 remains inoperative.
  • the second discharging valve 177 may be closed to prevent moisture and odors generated by the fluid collected in the storage unit 171 from flowing backward into the processing space 125, or back into the steam housing 142, where it could be used during a subsequent steaming operation.
  • fluid discharging valves of the fluid discharging device 170 are shown in FIG. 6 . More specifically, fluid discharging valves may be independently provided on the plurality of fluid discharging channels, as illustrated in FIG. 5 , or a valve assembly 180 may be connected to the plurality of fluid discharging channels at the storage unit 171, as illustrated in FIG. 6 .
  • the valve assembly 180 may include a valve body 181 that is connected to the storage unit 171, and a fluid discharging valve 182 connected to the first and second discharging channels 174 and 175.
  • the fluid discharging valve 182 may include an outlet 183 connected to the valve body 181 and two inlets 184 and 185 that correspond to the first and second discharging channels 174 and 175.
  • the discharging valve 182 may include first and second discharging valves that share the outlet 183 and that correspond to the inlets 184 and 185.
  • the processing apparatus 100 operates the steam supplying device 140 to supply steam to the processing space 125, and then operates the dry air supplying device 150 to supply dry air to the processing space 125 when the steaming process is completed.
  • the fabric articles arranged in the processing space 125 are refreshed by the steaming process and the drying process.
  • the steaming process and the drying process will be described in more detail.
  • fluid is supplied from the fluid supply tank 141 to the steam housing 142, and the fluid in the steam housing 142 is heated by the steaming heater 143 to generate steam.
  • the steam flows to the steam nozzle 144 along the steam channel 147 and is injected to the inner case 120 through the steam nozzle 144 to remove wrinkles and odors from the fabric articles in the processing space 125.
  • the drying process may be carried out after the steaming process has been completed.
  • the blower fan 152 of the dry air supplying device 150 is operated, and dry air is introduced into the drying housing 151 through the air receiving hole 128 and the air suction duct 131.
  • This dry air is heated by the drying heater, and the dry, heated air is discharged into the processing space 125 through the discharging hole 154 of the drying housing 151.
  • the high temperature dry air absorbs moisture from the fabric articles that have been refreshed by the steam supplied during the steaming process. Moisture laden air is discharged to the outside of the processing space 125 through the air discharging hole 127 and the air discharging duct 130.
  • the high temperature steam supplied by the steam supplying device 140 may be condensed so that condensed fluid is generated in the inner case 120. This may occur because the temperature of the inner case 120 may be lower than the temperature of the steam at an initial stage of the steaming process. When this happens, the inner case 120 may be saturated with moisture at a latter portion of the steaming process.
  • the condensed fluid may also be generated in the inner case 120 during the drying process. This may occur because, although dry air is supplied to the inner case 120, the temperature in the vicinity of the air discharging hole 127 of the inner case 120 may be relatively low, causing the humid air discharged through the air discharging hole 127 to be condensed.
  • the first fluid discharging valve 176 of the fluid discharging device 170 is opened so that the condensed fluid in the inner case 120 may be discharged to the storage unit 171. More specifically, condensed fluid generated during the steaming process and the drying process may flow to the lower side of the inner case 120 along the inner surface of the inner case 120 and may be discharged to the first fluid discharging channel 174 connected to the bottom surface unit 123 of the inner case 120. Then, the condensed fluid flows along the first fluid discharging channel 174 to the first fluid discharging valve 176.
  • the condensed fluid may flow into the storage unit 171. Therefore, since it is possible to prevent accumulation of condensed fluid in the processing space 125 and subsequent deterioration of the efficiency of the drying process, a drying time may be reduced and energy may be conserved.
  • the second fluid discharging valve 177 remains closed to prevent the fluid stored in the steam housing 142 from leaking into the second fluid discharging channel 175. That is, when the second fluid discharging valve 177 is closed during operation of the processing apparatus 100, the fluid is stably stored in the steam housing 142, thus preventing waste. Further, the steaming heater 143 does not sink in the fluid in the steam housing 142, but is exposed to the outside to prevent the steaming heater 143 from being overheated. Therefore, the stability and reliability of the steam supplying device 140 may be enhanced.
  • the first and second fluid discharging valves 176 and 177 may be closed to prevent odors and moisture from flowing backward into the inner case 120 or the steaming housing 142.
  • the second fluid discharging valve 177 may be opened for a set time to allow residual fluid to be drained from the steaming housing 142. After the set time has elapsed, the second fluid discharging valve 177 may be closed to prevent backflow as described above.
  • the apparatus 100 stops operating and the first fluid discharging valve 176 is closed, it is possible to prevent odors and moisture generated by the fluid collected in the storage unit 171 from being introduced into the inner case 120 through the first fluid discharging channel 174. Therefore, it is possible to prevent the fabric articles refreshed by the steaming process and the drying process from being re-contaminated by odors and moisture flowing backward into the inner case 120.
  • the processing apparatus 100 has stopped operating and the second fluid discharging valve 177 is opened for the set time, the residual fluid in the steam housing 142 is discharged to the storage unit 171 along the second fluid discharging channel 175. Therefore, it is possible to prevent the fluid remaining after the steaming process from being left in the steaming housing 142 for a long time.
  • moisture and odors generated by this residual fluid may be introduced into the inner case 120, or steam may be generated from this rotten residual fluid in a subsequent steaming process.
  • FIG. 7 is a sectional view of a clothes processing apparatus according to another embodiment as broadly described herein, and FIG. 8 is an associated schematic flow diagram.
  • the fabric processing apparatus 200 illustrated in FIGs. 7 and 8 is different from the fabric processing apparatus 100 illustrated in FIGs. 1 to 5 in that it may include a condensing chamber 229.
  • the condensing chamber 229 may be formed between the inner case 120 and the outer case 110, and may be connected to the storage unit 171 by a third fluid discharging channel 278 and a third fluid discharging valve 279.
  • the condensing chamber 229 may condense humid air discharged from the processing space 125.
  • the condensing chamber 229 may be formed between the rear surface unit 124 of the inner case 120 and a corresponding inner surface of the outer case 110. Condensed air from the condensing chamber 229 may be introduced into the processing space 125 through the air receiving hole 128 formed in the lower part of the rear surface unit 124.
