BACKGROUND
Field
[0001] The present disclosure relates to a laundry treating apparatus, and more particularly to a laundry treating apparatus including an output unit configured to output a screen.
Discussion of the Related Art
[0002] A laundry treating apparatus is an apparatus that performs a laundry treating process, such as loading clothing, bedding, etc. (hereinafter referred to as laundry) into a drum and removing contaminants from the laundry.
[0003] The laundry treating apparatus may perform processes such as washing, rinsing, spin-drying, and drying of laundry, and the laundry treating apparatus may be categorized into a top-loading type laundry treating apparatus and a front-loading type laundry treating apparatus based on a method of loading laundry into the drum.
[0004] The laundry treating apparatus may include a cabinet defining the appearance thereof, a tub received in the cabinet, a drum which is rotatably mounted in the tub and into which laundry is loaded, and a detergent supply device configured to supply detergent into the drum.
[0005] When the laundry treating apparatus is configured to wash laundry, the drum may be rotated by a motor in the state in which water and detergent are supplied to the laundry received in the drum, and the laundry may be removed by friction between the drum and washing water.
[0006] The detergent supply device has a detergent supply function to improve the washing effect. Here, the detergent means a material that improves the washing effect, such as fabric detergent, fabric softener, and fabric bleach. The detergent may be powdered detergent or liquid detergent.
[0007] When the laundry treating apparatus is configured to dry laundry, on the other hand, the laundry treating apparatus may provide dry air to the laundry to remove moisture from the laundry.
[0008] The laundry treating apparatus may include a cabinet, a drum rotatably provided in the cabinet, and a heating means configured to heat or dry air provided to the laundry.
[0009] As dry air is provided to the laundry received in the drum, moisture present in the laundry may be evaporated and removed by the dry air, whereby the laundry may be dried.
[0010] Meanwhile, when the amount of laundry is large or when different processes, such as washing and drying of the laundry, are to be performed together, a plurality of laundry treating apparatuses may be used.
[0011] Related document KR 10-2008-0021921 A1 discloses a laundry treating apparatus including a plurality of treating apparatuses. The apparatus disclosed in the related document includes a first treating apparatus and a second treating apparatus.
[0012] Each of the first treating apparatus and the second treating apparatus of the related document includes a drum provided in a cabinet to perform a laundry treating process. Meanwhile, each of the first treating apparatus and the second treating apparatus is provided with a control panel.
[0013] The control panel may be provided with an output unit configured to output a screen. Accordingly, the first treating apparatus and the second treating apparatus of the related document may provide different kinds of information through the respective output units.
[0014] However, when the first treating apparatus and the second treating apparatus perform independent treating processes, outputting information through the output unit of each of the first treating apparatus and the second treating apparatus may be inconvenient because a user must check the plurality of output units and provision of a separate output unit for each treating apparatus may increase the manufacturing process time and complicate the design of the control panel.
[0015] In addition, when information of different treating apparatuses is to be provided through one output unit, if a button configured to change the treating apparatus from which information is output is provided on one screen, the design and structure of the control panel, etc. may be complicated, ease of use of the button separated from the screen may be reduced, and it may be difficult for the user to identify how to use the button, etc.
[0016] For example, if there is a plurality of buttons, each of which performs a single command, it may be difficult to identify which button is used for which apparatus, and manufacture may be more expensive and time-consuming than if there is a single button.
[0017] In addition, when courses of the first treating apparatus and the second treating apparatus are performed simultaneously, if a single button is used to operate both apparatuses, the apparatuses are simultaneously operated or stopped, and therefore it is not possible to operate or stop only one apparatus.
[0018] Furthermore, when the first treating apparatus and/or the second treating apparatus is operated in any one of a plurality of modes, such as a washing mode for washing and a drying mode for drying, the user may not be able to easily check the selection of the mode and the selection of the apparatus and may be confused about the selection.
[0019] Therefore, it is important in the art to which the present disclosure pertains to enable convenient selection and operation of a plurality of treating apparatuses using a single start-stop button and a single output unit, to enable effective selection of a plurality of modes that can be performed by a single treating apparatus in order to perform an efficient laundry treating process, and to enable selection and operation of only one apparatus when cycles are simultaneously performed.
