spray nozzle 119, since fabric is uniformly and sufficiently soaked, rinsing effect can be improved even with a small amount of water. - At the water spraying S120, the
controller 190 controls the drivingapparatus 150 and rotates thewashing tub 140. Since thewashing tub 140 is rotated, water can be uniformly sprayed inside thewashing tub 140. - When fabric is sufficiently soaked inside the
washing tub 140, thecontroller 190 opens thesecond valve 162 and performs a fabric softener supplying process where water containing fabric softener is supplied through thedetergent box 118 to the washing tub S130. - The fabric softener supplying S130 is started after the water spraying process S120 is performed for predetermined time duration.
- In the fabric softener supplying S130, the
controller 190 opens thesecond valve 162 and makes water supplied from the outside flow to thedetergent box 118. Since fabric softener is already stored inside thedetergent box 118, water flowed into thedetergent box 118 is combined with fabric softener stored and thus, can be supplied to thewashing tub 140. - In the fabric softener supplying S130, the
controller 190 controls the drivingapparatus 150 and rotates thewashing tub 140. - Meanwhile, the fabric softener supplying S130 can be started after the water spraying S120 is terminated; at the same time, the fabric softener supplying S130 can be started while the water spraying S120 is underway.
- At this time, it is assumed that if a predetermined time is passed from when the water spraying S120 has started, the fabric softener supplying S130 is also performed with the water spraying S120. In other words, if fabric is getting fully wet through the water spraying S120, the fabric softener supplying S130 is started. Therefore, since the fabric softener is supplied while the fabric has become wet in some degree as the water spraying S120 is performed, the fabric softener can be spread out evenly over the fabric without being massed into lumps.
- Also, even if the fabric softener supplying S130 is started, the water spraying S120 is performed without stopping.
- When the second
fluid path 164 is opened and the fabric softener is supplied, the firstfluid path 163 is still kept opened and water not containing detergent can be continuously supplied through thespray nozzle 119. - The first
fluid path 163 and the secondfluid path 164 are both opened and water can be supplied through both thespray nozzle 119 and thedetergent box 118. At the time of supplying fabric softener, since water supply is performed through thespray nozzle 119, fabric softener can be spread uniformly. - In a washing machine according to the present embodiment, the first
fluid path 163 and the secondfluid path 164 are disposed separately; therefore, when water not containing detergent is supplied through thespray nozzle 119 during rinsing course, supply of fabric softener is made possible. - Also, since water is supplied through the
spray nozzle 119, amount of water consumed during rinsing course can be reduced. - Meanwhile, not limited to the embodiment, opening the
first valve 161 after opening thesecond valve 162 first is also possible. -
