BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine, and more particularly, to a washing machine having a convenient user interface. More specifically, the present invention relates to a washing machine that provides a simple yet intuitive user interface.

The washing machine is a washing machine for washing clothing, and the dryer for drying clothes is also a washing machine. Of course, a washing machine or dryer capable of washing and drying clothes is also a washing machine.

Recently, a refresher for refreshing clothes using hot air or steam instead of washing with water has been put on the market, which is also called a washing machine.

In the following description, a washing machine will be mainly described as a representative example of the washing machine, and other washing machines may be used as long as they are exclusive and not inconsistent with other machines.

1 shows a control panel of a conventional washing machine.

A control panel is provided for the user interface. Therefore, it is generally provided on the front of the washing machine so that the user can easily access and manipulate the washing machine. The control panel may include an input unit or a selection unit such as various buttons for user's operation and various display units for providing information to the user. Such various input units, selection units, and display units may all be referred to as user interfaces.

The main function of the washing machine is washing. Accordingly, a course selection unit 110 or a main function selection unit for selecting various laundry courses is provided, and the user selects a course through the course selection unit 110. For example, the course selection unit 110 may be provided as a rotary knob. The control panel 100 may be provided with a course display unit 111 for facilitating user selection of a course and the user may select a desired laundry course by operating the course selection unit 110 to correspond to the course display unit. When the course selection unit 110 is operated, the course selected through the course display unit 111 can be identified.

FIG. 1 shows a course display unit 111 having various washing courses displayed around the rotary knob 110, and the user can select a washing course corresponding to the rotated rotary knob 110 by rotating the rotary knob 110. A display unit 121 for displaying the selected laundry course can be provided, so that the user can easily grasp the selected laundry course. That is, the user can easily recognize the selected laundry course through the course display unit 111 and the LED display unit 121 blinked correspondingly. The course display unit 111 may be printed on the front surface of the control panel.

An option selecting unit 120 may be provided to select an option function added or changed in performing the main function described above. The option selection unit 120 may be variously provided. In FIG. 1, for example, an option for selecting options related to the laundry 120a, rinsing 120b, dewatering 120c, water temperature 120d, drying 120e, steam 122, An input unit 120 is shown. An option display unit 122 may be provided to indicate whether the option is selected or may be implemented through an LED or the like.

The control panel 100 may include a status display unit 130 for displaying the status of the washing machine. The state of the current washing machine, the user's course or option selection state, time information, and the like can be displayed through the status display unit 130. In general, the status display unit 130 may be provided as a liquid crystal display.

For example, if the current washing machine is performing a rinsing step, it may be indicated as "during the rinsing step ". And, when waiting for the user to enter the course, it can be displayed as "Please enter laundry course". It is also possible to display the remaining time (remaining time) until the current time or the washing machine completes the operation by completing all the washing courses.

Meanwhile, the control panel 100 may include a power input unit 140 for applying and releasing power to the washing machine, and a start / pause input unit 150 for executing a washing operation or temporarily stopping the washing machine.

The conventional control panel 100 and the washing apparatus including the control panel 100 have the following problems.

There is a problem in that it is difficult to implement an additional user interface in addition to the configuration for the basic user interface due to the space problem of the control panel 100. [ Of course, complex and diverse user interfaces may be implemented in the control panel 100, but this presents a problem that requires excessive concentration and prior knowledge of the user. Further, it is difficult to manufacture the control panel 100 or a high-capacity memory is required, which causes a problem that the washing machine itself becomes excessively expensive.

In addition, since the functions of the selectors 110 and 120 and the display units 111, 121, and 122 are preset or set, there is a problem that it is difficult to expand the functions for the additional functions. In addition, the various selection units 110 and 120 are directly exposed to the user. That is, unnecessary selection units as well as necessary selection units at a specific time point are exposed to the user. Therefore, there is a problem that various functions provided by the washing machine are not used when the user is not a skilled user.

Also, since the number of the selection units 110 and 120 and the display units 111, 121, and 122 is large and scattered, the user interface is very inconvenient. That is, in order to grasp the information inputted by the user into the washing machine, there is a problem that the gaze must be fixed to each of the components.

Recently, the design of household appliances has adopted a lot of minimal design. In addition, there is a growing demand for a simple yet intuitive user interface rather than a complex user interface. However, it is not easy to implement a simple and intuitive user interface in a washing machine. This is because it is necessary to provide at least a simple and intuitive user interface while including at least all of the user interfaces shown in Fig. In addition, it is necessary to allow a user who is familiar with a conventional user interface to adapt to a new user interface without much difficulty.

Due to these various difficulties, it has not been easy to change the conventional user interface.

On the other hand, as shown in Fig. 1, the number of courses that the washing machine basically provides is preset. For example, 12 laundry courses are shown in Fig. Accordingly, it is difficult to add a new washing course, and even if it is added, it is inevitable to select an additional course through a separate option button or the like without going through the course selection unit 110. That is, although a course is selected at the same level, the course must be selected through another selection unit (for example, the shoes refresh course 124) other than the course selection unit 110. Therefore, There is a problem that it is not easy to use an additional laundry course.
