control unit 60 determines whether the scheduled operation is set by user s handling of theoperation panel 20 or not (S310). If the scheduled operation is not set, thecontrol unit 60 puts thelaundry machine 100 into operation directly according to setting of washing the user selected (S350). - In the meantime, if the scheduled operation is set by the user, the
control unit 60 determines if the scheduled operation is the saving electricity scheduled operation or not (S320). If the scheduled operation is general scheduled operation (that is, scheduled operation not related to the saving electricity time period), thecontrol unit 60 waits until an operation time set by the user comes (S330). Then, as a time of the scheduled operation comes, thecontrol unit 60 puts thelaundry machine 100 into operation according to the setting of washing the user selected (S350). - In this instance, if the scheduled operation set by the user is the saving electricity scheduled operation, the
control unit 60 determines if the preset saving electricity time period is come (S340). - In this instance, if the saving electricity time period does not come yet, a waiting state is maintained, and if the saving electricity time period comes, the
laundry machine 100 is put into operation according to the setting of washing the user selects (S350). - In the meantime, the saving electricity scheduled operation can cause a problem of noise since most of the saving electricity is supplied in a midnight time period. According to this, the saving electricity scheduled operation is possible to use the midnight mode scheduled operation.
-
FIG. 8 illustrates a flow chart showing the steps of a method for making midnight mode scheduled operation of a laundry machine in accordance with a preferred embodiment of the present invention. - The
control unit 60 determines whether the scheduled operation is set by user s handling of theoperation panel 20 or not (S410). If the scheduled operation is not set, thecontrol unit 60 puts thelaundry machine 100 into operation directly according to setting of washing the user selected (S440). - In the meantime, if the scheduled operation is set by the user, the
control unit 60 determines if the scheduled operation is the saving electricity scheduled operation or not (S420). If the scheduled operation is general scheduled operation (that is, scheduled operation not related to the saving electricity time period), thecontrol unit 60 waits until an operation time set by the user comes (S430). Then, as a time of the scheduled operation comes, thecontrol unit 60 puts thelaundry machine 100 into operation according to the setting of washing the user selected (S440). - In this instance, if the scheduled operation set by the user is the saving electricity scheduled operation, the
control unit 60 determines if the preset saving electricity time period is come (S450). In this instance, if the saving electricity time period does not come yet, a waiting state is maintained. - Thereafter, if the saving electricity time period comes, the control unit determines if the user s setting of washing is the midnight mode. If not, the
control unit 60 puts thelaundry machine 100 into operation according to preset setting of washing mode to perform a washing course. (S470). - In the meantime, if the setting of washing the user selects is the midnight mode, the
control unit 60 performs washing prior to the spinning mode in which noise is heavy in a preset washing mode (S490). In this instance, thecontrol unit 60 displays that the spinning course is omitted in the scheduled operation at the midnightmode display unit 28 b for the user to notice. - In the meantime, if the user sets that the spinning course is performed in the midnight scheduled operation, the
control unit 60 may perform tumbling in which thedrum 50 is rotated at fixed intervals repeatedly until the midnight time period ends (or a time the user sets) after the midnight spinning course performed so that no crumple is formed at the laundry of which spinning is progressed (S480). - Though, the midnight mode scheduled operation is described with the saving electricity scheduled operation, the midnight mode scheduled operation can be performed individually with no relation to the saving electricity scheduled operation. In this case, the control unit determines the midnight mode when the scheduled operation is started, and performs operation of the midnight mode.
- In the meantime, the barrel washing of the laundry machine can be performed in the midnight time period by using the saving electricity. In this case, comparatively cheap saving electricity can be used.
-
FIG. 9 illustrates a flow chart showing the steps of a method for making barrel washing scheduled operation of a laundry machine in accordance with a preferred embodiment of the present invention. - The
control unit 60 detects a setting state of the barrel washing as the barrel washing is set by user s handling of the operation panel 20 (S510). - Then, the
control unit 60 determines whether the barrel washing the user sets is the scheduled operation or not (S520). If no barrel washing scheduled operation is set individually, thecontrol unit 60 puts thelaundry machine 100 into operation directly according to the setting of the barrel washing the user selects, to progress the barrel washing by supplying washing water and detergent (S530). In this instance, if the barrel washing scheduled operation the user sets is general scheduled operation (that is, scheduled operation not related to the saving electricity time period), thecontrol unit 60 waits until an operation time set by the user comes (S550). Then, as a time of the scheduled operation comes, thecontrol unit 60 puts thelaundry machine 100 into operation according to the setting of barrel washing the user selected, to perform the barrel washing by supplying washing water and detergent (S560). - In this instance, if the barrel washing scheduled operation the user sets is the saving electricity scheduled operation, at first, the
control unit 60 supplies washing water and detergent for the barrel washing (S570). - Then, the
control unit 60 determines whether a preset saving electricity time period comes or not. If the saving electricity time period does not come yet, a waiting state is maintained (S580). - In the meantime, if the saving electricity time period comes, the
control unit 60 performs the barrel washing by using the washing water, and the detergent supplied in advance, and rotation power of thedrum 50 according to barrel washing setting the user selects (S590). - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
