• a washing machine is an electric home appliance capable of washing clothing or laundry
• a drying machine is an electric home appliance capable of drying wet clothing or laundry.
• electric home appliances combining the functions of the washing machine and the drying machine have been widely used.
• the washing machine, the drying machine, and the electric home appliances combining the functions of thereof will be commonly referred to as a laundry machine.
• Laundry machines are generally classified into a top loading type and a front loading type according to the way in which the laundry is input into the laundry machine. Further, laundry machines may be classified into a vertical axis type in which a drum or a pulsator rotates about a vertical axis and a horizontal axis type in which a drum rotates about a horizontal axis.
• a horizontal type laundry machine is a front loading drum laundry machine or a drum dryer.
• Laundry machines are generally installed on a surface so that an inlet of the front loading drum laundry machine is low enough that it is inconvenient for a user to put laundry into and take laundry out of the laundry machine. Therefore, there is a need for the height of the inlet of the laundry machine to be increased.
• each home has only one laundry machine. Therefore, when a user desires to classify and wash laundry according to different types thereof, the washing machine must be used several times. For example, when laundry is divided into, for example, adult clothing and laundry, such as underwear and baby clothing, the washing machine must be used two or more times to wash the different types of laundry. The multiple washings take up time and consume a lot of energy. [38] Also, in order to conserve energy, it is preferable not to use a large-sized laundry machine when washing a small amount of clothing. The washing course provided in the large-sized laundry machine generally consumes a large amount of washing water. Further, a lot of power is consumed rotating a large-sized drum or pulsator.
• the washing course of a large-sized laundry machine is configured for a large amount of laundry, the washing time is comparatively long. Further, the large- sized laundry machine is provided with a washing course that is configured mainly for general clothing, so that it may not be suitable for washing delicate clothing, such as underwear or baby clothing.
