Therefore, the exhaust pipe 422, the steam conducting pipe 340, the branch pipe 351, and the steam tube 353 are illustrated as a guide pipe.
  • the pump 330 performing the intermittent water supply operation emits a suitable amount of water to the high temperature chamber space 430, the water evaporates instantaneously.
  • the internal pressure of the chamber space 430 rapidly increases. Therefore, the steam is injected from the nozzle 352 at a high pressure, and traverses the internal space of the storage tank 200 up and down. In the vicinity of the lower end of the rotating drum 210, the clothes are easily collected by gravity. The steam jetted from the nozzle 352 attached to the upper portion of the storage tank 200 reaches near the lower end of the rotary drum 210, so the steam is efficiently supplied to the clothes.

  • the included angle ⁇ 1 is an obtuse angle
  • the included angle ⁇ 2 is an acute angle. Since the included angle ⁇ 2 is an acute angle, the flow loss from the parent pipe 354 to the lower pipe 356 is relatively large. Therefore, the steam that has flowed into the parent pipe 354 hardly flows into the lower pipe 356 but mainly flows into the upper pipe 355.
  • the upper child pipe 355 defines an upward flow path, the water flowing into the parent pipe 354 hardly flows into the upper child pipe 355 due to the action of gravity but mainly flows into the lower child pipe 356. Therefore, the flow path of the steam and the flow path of the water are properly separated.
  • FIG. 13 is a graph schematically showing the relationship between the intermittent operation of pump 330 and the temperature in chamber space 430. The intermittent operation of the pump 330 will be described with reference to FIGS. 8, 11 and 13.
  • the period during which the pump 330 is operating (ON period) is set shorter than the period during which the pump 330 is stopped (OFF period). As a result, an appropriate amount of water is emitted into the chamber space 430.
  • the chamber space 430 is supplied with a predetermined amount of water. As a result, the water evaporates and becomes steam. The heat of vaporization resulting from the water-to-vapor phase change temporarily reduces the temperature of the chamber space 430. As described above, since the off period is set to be relatively long, the heater 425 can sufficiently heat the chamber space 430 during the off period. Therefore, while the pump 330 is performing intermittent operation, high pressure steam continues to be supplied to the storage tank 200. In particular, the chamber space 430 is sufficiently heated during the OFF period, and during the ON period, an appropriate amount of water that instantaneously evaporates is supplied to the thermal energy of the steam generator 420 including the chamber space 430. (For example, about 2 cc / time), the high pressure steam will continue to be supplied to the storage tank 200.

Thereafter, the water in the water tank 220 is heated using the hot water heater 160. Since the hot water heater 160 emits a large amount of heat, the temperature of the water contained in the clothes in the water tank 220 rapidly rises. Thereafter, when the predetermined temperature is reached, the heating of the water in the water tank 220 is stopped.
  • the dotted line after the heating stop represents the change in the temperature of the water contained in the clothes when the heating by the warm water heater 160 is stopped and the supply of steam is not performed.
  • the solid line after the heating stop represents the change in the temperature of the water contained in the clothes when the heating by the hot water heater 160 is stopped and the steam is supplied to the storage tank 200.
  • the steam supplied to the storage tank 200 is high temperature and is directly supplied to the clothes as described above, the temperature drop of the water contained in the clothes in the water tank 220 is alleviated.
  • the heater 425 used for the steam generator 420 consumes less power than the hot water heater 160 attached to the water tank 220. Therefore, as compared with the heat retention of the water in the water tank 220 using the hot water heater 160, the heat retention by the steam supply can achieve less power consumption. Therefore, it is preferable that the pump 330 perform intermittent water supply operation after the hot water heater 160 is stopped.

As a result, the moisture contained in the clothes is released out of the rotating drum 210 through the small holes 219. Thus, the garment is properly dewatered.
  • the fibers of the dehydrated garment tend to hydrogen bond with each other.
  • the hydrogen bonds between the fibers result in the heel of the garment.
  • the steam breaks the hydrogen bond between the fibers.
  • the wrinkles of the clothes are reduced. Therefore, it is preferable for the pump 330 to perform an intermittent water supply operation while the garment is being dewatered.
  • steam is injected from the nozzle 352 into the rotating drum 210 at high pressure.
  • the steam jetted from the nozzle 352 crosses the storage tank 200, the steam sticks to the peripheral wall 211 and is evenly sprayed to the rotating clothing. As a result, wrinkles are less likely to occur over the entire clothes in the rotating drum 210.

  • the steam supply mechanism 300 may start the supply of steam after a predetermined period (T1) has elapsed from the start of the dehydration process. In this case, since the clothes contain less moisture, the clothes are efficiently wetted by the heat of the steam and the moisture. As shown in FIGS. 15B and 15C, the steam supply mechanism 300 may start supplying steam in synchronization with the start of the dewatering process. In this case, the clothes are heated at an early stage of the dewatering process, so the clothes are effectively wetted at high temperature. As shown in FIGS. 15A and 15B, the steam supply mechanism 300 may supply steam during part of the dewatering process. As shown in FIG. 15C, the period during which the steam supply mechanism 300 supplies steam may correspond to the period from the start to the end of the dehydration step.
  • the steam generator 420 With the end of the treatment of the garment with steam, the steam generator 420 is preferably cooled. If the steam generator 420 is cooled, the injection of high temperature steam into the unnecessary storage tank 200 is prevented.
  • the power supply to the heater 425 is stopped to cool the steam generator 420. Thereafter, the pump 330 starts a continuous water supply operation. As a result, water continuously flows into the chamber space 430 from the water reservoir 320. The water flowing into the chamber space 430 removes heat from the steam generator 420 and flows into the storage tank 200. Thus, the steam generator 420 is cooled in a short period of time.
