BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a washer, by which information for an operational state of the washer is scrolled on a display by setting up a scroll direction through a simple operation.
2. Discussion of the Related Art
Generally, a washer is an apparatus for removing filth from laundry. Water is supplied enough for the laundry to be submerged under the water. An appropriate amount of detergent is dissolved in the water to remove the filth attached to the laundry by chemical reaction with the detergent. A tub holding the laundry therein is rotated to generate mechanical friction or vibration between the water and the laundry to facilitate the removal of the filth from the laundry.
A washer according to a related art, as shown in FIG. 1, generally includes an input unit for selecting a step of a washing cycle of washing, rinsing, or dewatering and reserving the selected washing cycle and a display unit displaying a reserved time or a time of the reserved washing cycle.
The washer includes a tub receiving laundry therein, a motor rotating the tub, a microcomputer controlling the washing cycle of the washer and overall items of the washer, and water supply and drain valves turned on/off by a control of the microcomputer. Hence, the washer carries out the washing cycle of the laundry received in the tub according to the washing cycle selected by the input unit.
The display unit displays the reserved time and an operational time according to the washing cycle of the washer via LED. The display unit displays setup items for washing water and hot/cold water in a manner of turning on LED.
Moreover, the display unit may consist of a liquid crystal display (LCD) through which characters indicating information appear to enable a user to understand an operational state of the washer.
However, the display unit displays the data limited to the basic washing only. Even if the liquid crystal display is employed, a multitude of procedures need to be executed to check a lot of information. Hence, it is difficult for a user to recognize the details of the washing cycle.
Moreover, in case of displaying a lot of information by enlarging a size of the liquid crystal display, a size of the display unit of the washer needs to be increased accordingly and a product cost is raised.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Reference will now be made in detail to the preferred embodiment of the present invention, examples of which are illustrated in the accompanying drawings. Throughout the drawings, like elements are indicated using the same or similar reference designations where possible.
As shown in FIG. 2 and FIG. 3, a washer according to the present invention includes a display 30 transferring a large amount of information by scrolling an operational state for a washing cycle of the washer and an input unit 10 receiving setup items for the washing cycle such as a water supply quantity, a washing course, and the like according to a user selection. The washer further includes a microcomputer 20 performing the washing cycle according to the setup items inputted via the input unit 10 and implementing information of the washing cycle of the washer to be displayed via the display 30 by scrolling.
The input unit 10 includes a button unit 11 configured with a plurality of option buttons for setting up an operation for the washing cycle and a dial unit 12 for setting up the washing cycle according to a washing course and laundry. Specifically, if at least two of a plurality of the option buttons are randomly pressed during several seconds simultaneously, the display 30 is switched to a menu mode for setting up a scroll direction by the button unit 11. The selected scroll setup is stored by a power button of a plurality of the buttons. In doing so, the dial unit 12 sets up the scroll direction by a rotational operation of the dial in case of the scroll setup state by the button unit 11. An initial value of the scroll direction is set up by a left scroll, as shown in FIG. 4. The dial unit 12 changes the scroll direction into a left, right, up, or down direction according to each rotational operation of the dial. The dial unit 12 makes the setup of the scroll direction appear repeatedly in case of a continuous rotational operation of the dial.
The microcomputer 20 includes an input processor 21 processing contents inputted from the random button input of the button unit 11 and the dial unit 12 and a display controller 22 scrolling a large quantity of information on the display 30 according to a value set by the input processor 21. The input processor 21 enables the washing cycle according to a general input of the button unit 11. In case that at least two random buttons are pressed for several seconds, the input processor 21 recognizes the inputs of the button unit 11 and the dial unit 12 as an input for a scroll setup and then sets up the scroll direction. If the power button is pressed, the input processor 21 allows the scroll setup to be stored. The display controller 22 displays a scroll setup menu on the display 30 according to the above selected and stored setup and allows the information of the washing cycle of the washer to be scrolled on the display 30.
Hence, even if the display 30 of the washer is provided with a small liquid crystal display, the state information of the washer is scrolled thereon to transfer a large quantity of information to a user. Thus, the present invention can reduce an area occupied by the display of the washer for which a large display is unnecessary.
Referring to FIG. 5, illustrating an operational method of the washer according to the present invention, power of the washer is turned on and a general washing cycle setup is then selected/inputted by a user. The washer executes the corresponding washing cycle and an operational state of the washer appears via the display. In case of intending to see information of the washer by scrolling, the user simultaneously presses at least two of the option buttons for several seconds randomly to enable a scroll setup state (S1). In doing so, the previous information of the operational state of the washer disappears and a menu for setting the scroll direction appears on the display 30 of the washer 30 (S2). A menu for changing the scroll direction appears on the scroll setup menu and an initial value of the scroll direction is set by a left scroll. In case of one rotational operation of the dial, the scroll direction is switched to a right scroll from the left scroll. In case of one further rotational operation of the dial, the scroll setup is switched to an upward scroll. In case of several rotational operations of the dial, the scroll direction of the scroll setup is switched to left, right, upward, and downward directions. Such a setup is repeatedly displayed (S3). After completion of setting the scroll direction, the power button is pressed to store the set scroll information (S4). After completion of the scroll setup, the information of the washing cycle of the washer is scrolled on the display according to the set scroll information (S5).
Accordingly, the present invention sets up the information of the washing cycle to be scrolled using the previous buttons, thereby enabling the small display of the washer to display a large quantity of information with simple operations. Therefore, the present invention enhances user convenience and reduces the size of a display to lower product cost.
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 such modifications and variations, provided they come within the scope of the appended claims and their equivalents.
