In this regard, the operation of the washing machine related to the general washing stroke, rinsing stroke, dehydration stroke, drying stroke, etc. of the washing machine may blur the gist of the present invention, and thus, detailed description thereof will be omitted.

Hereinafter, with reference to the accompanying drawings with respect to the reservation operation of the late night time zone using the laundry machine according to an embodiment of the present invention will be described in detail.

5 is a flowchart illustrating a washing method of a laundry machine according to an embodiment of the present invention.

First, referring to the reservation operation setting process by the user, if the user selects the reservation operation mode according to the operation of the late-night mode selection button 27a (or the power saving electricity selection button 29a) provided on the operation unit 22, the control unit 60 The user can recognize the reservation mode through the late-night mode display unit 27b (or the power saving display unit 29b) provided in the display unit 26.

The controller 60 determines whether the reservation operation is set as the user inputs the washing start signal through the operation panel (step S101). At this time, if a separate reservation operation is not set, the control unit 60 immediately operates the washing apparatus 100 according to the washing setting selected by the user, and performs the washing administration (step S201), rinsing stroke (step S202), and dehydrating stroke (step S203) proceeds sequentially. At this time, although not shown, an additional drying stroke, steam stroke, and the like may be further performed.

On the other hand, when the reservation operation is set, the controller 60 determines whether the set reservation operation time has arrived, and waits until the reservation time arrives (step S102).

Here, when the reservation operation time arrives, it is determined whether the set reservation operation is set in the late night mode (that is, the late night time zone or the power saving time zone) (step S103).

At this time, if the midnight mode is not set (that is, reservation operation irrespective of the late night time zone or the power saving time zone), the washing machine 100 is operated according to the washing setting selected by the user to perform the washing administration (step S201) and the rinsing stroke (step S202). ), The dehydration administration (step S203) is carried out sequentially. At this time, although not shown, an additional drying stroke, steam stroke, and the like may be further performed.

On the other hand, if the washing setting set by the user is a midnight mode, the control unit 60 performs the washing process only until the dehydration mode with a large noise generation in the preset washing mode.

That is, in the case of a washing administration without the dehydration process, the washing administration is performed in the same manner as the existing washing administration (step S104).

After the washing process, the rinsing process is performed. In the case of the rinsing stroke, the rinsing stroke is performed except for the simple dehydration performed to improve the rinsing performance between rinses during repeated rinsing. Since the rinsing performance may be reduced as long as the simple dehydration is excluded, additional rinsing may be performed (step S105).

After that, when the last rinsing of the rinsing cycle is completed, the controller 60 additionally supplies rinsing water to maintain the state in which the laundry is immersed in the rinsing water (step S106). This is because when the laundry is supplied with an appropriate amount of rinsing water, wrinkles may be prevented from occurring even when the laundry is left for a long time.

At this time, the control unit 60 displays that the user can recognize through the dehydration progress display unit 28b provided on the display unit 26 of the operation panel 20 that the drainage and dehydration stroke of the wash water is omitted during the reservation operation. Here, in the case of the dehydration progress display unit 28b, the dehydration progress display unit 28b may be flickered at predetermined time intervals to improve the user's awareness.

In addition, the control unit 60 may cut off power supplied to the washing apparatus 100 after step S106 and prevent waste of power. In this case, when the power is supplied again to the washing apparatus 100 by a user's operation later, the control unit 60 resumes the operation of the dehydration progress display unit 28b to indicate that drainage and dehydration administration have not proceeded.

On the other hand, the control unit 60 confirms the progress input of the dehydration administration through the dehydration progress button. At this time, if the dehydration administration progress by the user is not input, the standby state of step S106 is maintained continuously (step S107).

On the other hand, when the user inputs the progress of the dehydration stroke by operating the dehydration progress button 28a, the rinsing water remaining in the tub 30 is first drained and the dehydration stroke is performed (step S108).

That is, the user checks the dehydration progress display unit 28b of the display unit 26 as the reservation operation is completed and operates the dehydration progress button 28a provided in the operation unit 22 to separately perform the drainage and dehydration administration of the wash water. Can be.

Hereinafter, a reservation operation of a late night time zone using a laundry machine according to another embodiment of the present invention will be described in detail with reference to the accompanying drawings.

6 is a flowchart illustrating a washing method of a laundry machine according to another embodiment of the present invention.

First, referring to the reservation operation setting process by the user, if the user selects the reservation operation mode according to the operation of the late-night mode selection button 27a (or the power saving electricity selection button 29a) provided on the operation unit 22, the control unit 60 The user can recognize the reservation mode through the late-night mode display unit 27b (or the power saving display unit 29b) provided in the display unit 26.

The controller 60 determines whether the reservation operation is set as the user inputs the washing start signal through the operation panel (step S111). At this time, if a separate reservation operation is not set, the control unit 60 immediately operates the washing apparatus 100 according to the washing setting selected by the user, and performs the washing administration (step S201), rinsing stroke (step S202), and dehydrating stroke (step S203) proceeds sequentially. At this time, although not shown, an additional drying stroke, steam stroke, and the like may be further performed.

On the other hand, when the reservation operation is set, the controller 60 determines whether the set reservation operation time has arrived, and waits until the reservation time arrives (step S112).

Here, when the reservation operation time arrives, it is determined whether the set reservation operation is set in the late night mode (that is, the late night time zone or the power saving time zone) (step S113).

At this time, if the midnight mode is not set (that is, reservation operation irrespective of the late night time zone or the power saving time zone), the washing machine 100 is operated according to the washing setting selected by the user to perform the washing administration (step S201) and the rinsing stroke (step S202). ), The dehydration administration (step S203) is carried out sequentially. At this time, although not shown, an additional drying stroke, steam stroke, and the like may be further performed.

On the other hand, if the washing setting set by the user is a midnight mode, the control unit 60 performs the washing process only until the dehydration mode with a large noise generation in the preset washing mode.

That is, in the case of a washing administration without the dehydration process, the washing administration is performed in the same manner as the existing washing administration (step S114).

After the washing process, the rinsing process is performed. In the case of the rinsing stroke, the rinsing stroke is performed except for the simple dehydration performed to improve the rinsing performance between rinses during repeated rinsing. Since the rinsing performance may be reduced as long as the simple dehydration is excluded, additional rinsing may be performed (step S115).

Thereafter, the controller 60 drains and waits for the rinsing water used for the rinsing when the last rinsing of the rinsing stroke is completed (step S116).

At this time, the control unit 60 displays that the user can recognize through the dehydration progress display unit 28b provided on the display unit 26 of the operation panel 20 that the dehydration stroke of the wash water is omitted during the reservation operation. Here, in the case of the dehydration progress display unit 28b, the dehydration progress display unit 28b may be flickered at predetermined time intervals to improve the user's awareness.

In addition, the controller 60 may cut off the power supplied to the washing apparatus 100 after step S116 and prevent waste of power. In this case, when the power is supplied again to the washing apparatus 100 by a user's operation later, the control unit 60 resumes the operation of the dehydration progress display unit 28b to indicate that drainage and dehydration administration have not proceeded.

On the other hand, the control unit 60 confirms the progress input of the dehydration administration through the dehydration progress button. At this time, when the dehydration administration progress by the user is not input, the standby state of step S116 is maintained continuously (step S117).

On the other hand, when the user operates the dehydration progress button 28a to input the progress of the dehydration stroke, the rinsing water is additionally supplied to the tub 30 to proceed with the additional rinsing stroke (step S118).

This is to prevent wrinkling in the laundry by performing an additional rinsing because the laundry may be generated when the rinsing-completed laundry is left for a long time during the reservation operation.

Thereafter, the controller 60 drains the rinsing water remaining in the tub 30 and performs a dehydration stroke (step S108). That is, the user checks the dehydration progress display unit 28b of the display unit 26 as the reservation operation is completed and operates the dehydration progress button 28a provided in the operation unit 22 to separately perform the drainage and dehydration administration of the wash water. Can be.

Meanwhile, in the above description, the reservation operation of the late night time zone or the power saving time zone has been mainly described. However, if the operation time by the user is already included in the late night time zone or the power saving time zone, the process according to the reservation operation may be omitted. That is, in general, the midnight mode and the power saving mode can be applied during the washing process.
