On the other hand, the front of the washing apparatus may be provided with a control panel for controlling the driving of the washing apparatus.

2 is a front view showing a control panel 20 of the laundry machine according to FIG.

Referring to FIG. 2, one side of the control panel 20 includes a selection unit 30 for selecting a course of a washing machine, and a display unit 22 for displaying washing information and the like while the washing machine is driven.

Here, the selection unit 30 may include a main selection unit 32 capable of selecting a plurality of washing courses, and one or more sub-selection units capable of changing step conditions at one or more stages of the course selected by the main selection unit 32. (34, 35, 36, 37).

That is, the main selection unit 32 may be provided with a plurality of courses including at least one or more of washing, rinsing, dehydrating and drying. For example, the main selector 32 may include a standard course, a duvet course, a baby clothes course, an underwear course, a steam course, and the like. Each of these courses may include at least one or more steps of a washing step, a rinsing step, a dehydration step, and a drying step, and the washing apparatus is driven according to the selected course. Here, the main selection unit 32 may be made of a button type, but preferably made of a rotatable rotary type, so that the user can rotate the main selection unit 32 to select a desired course.

On the other hand, when the user selects the course by the main selection unit 32 as described above, according to each step of the selected course, step conditions may be set in advance in the control unit (not shown) and stored as default. For example, when the standard course is selected, the conditions for the water temperature in the washing step, the amount of water, the rinsing frequency in the rinsing step, the rinsing time, the spin speed of the dehydration step (rpm), and the drying time of the drying step are controlled in advance. Stored in, washing may proceed according to the stored conditions.

By the way, the conditions of each step as described above may be stored in advance in the control unit, it may be changed by the user's selection. In other words, the user may operate the sub-selectors 34, 35, 36, and 37 to change the conditions of the above-described steps. Accordingly, at least one sub-selector 34, 35, 36, 37 may be provided corresponding to each step of the selected course. In FIG. 2, four sub-selectors 34, 35, 36, and 37 are illustrated as being provided in response to washing, rinsing, dehydration, and drying. However, the sub-selectors 34, 35, 36, and 37 are not limited thereto. Do.

Meanwhile, one side of the control panel 20 further includes a power button 40 for turning on / off the power of the washing machine and a start button 42 for inputting a driving command to drive the selected course. It can be provided. The user can turn on / off the power of the washing machine by the power button 40, and start after finishing the selection by the main selecting part 32 and / or the sub selecting parts 34, 35, 36, 37. The washing machine can be driven by the button 42.

In the control panel 20 having the above configuration, the user first selects a desired course by the main selection unit 32, and then proceeds with a course selected according to a preset step condition by default, or a sub-selection unit. (34, 35, 36, 37) manipulates the step conditions to proceed to the selected course. However, as described above, when the step conditions are selected by the sub-selectors 34, 35, 36, and 37 after the course is selected by the main selector 32, it is necessary to operate the step conditions in a certain order. It is convenient for the user, and preferably it is convenient to manipulate the step conditions according to the steps of the washing procedure. However, the conventional washing machine is not equipped with a separate configuration, a device for guiding the user in the selection order of the sub-selector in order to operate the sub-selector after selecting the main course, it is inconvenient for the user to operate the sub-selector separately. There was this.

Therefore, in the embodiment of the present invention, when the user operates the main selection unit and the sub selection unit, the configuration is provided to guide the operation procedure, which will be described in detail with reference to the accompanying drawings.

Referring back to FIG. 2, although not shown in the drawing, a plurality of light emitting units for dimming each selection unit may be provided on the rear surfaces of the main selector 32 and the subselectors 34, 35, 36, and 37. Such a light emitting unit may be implemented in various forms, for example, it may be made of an LED. The LED-type light emitting unit may include a LED on the back of each selector, and a guide unit may be provided so that the light emitted from the LED illuminates the selector. In addition, at least a portion of each selection unit may be formed of a transparent material through which light can pass so that a user can recognize the light emitted from the light emitting unit.

On the other hand, the control unit of the washing machine is controlled to drive the washing machine according to the course selected by the main selection unit and the sub-selection unit, the selected step conditions, and to control the light emitting units for illuminating the main selection unit and the sub-selection unit . Hereinafter, look at in detail.

First, the user inserts the laundry object into the drum, and then turns on the power by operating the power button 40. As a result, the power is turned on by the washing machine, and the control unit turns on the light emitting unit for dimming the main selection unit 32 from the selection unit 30. As a result, the user knows that the main selection unit 32 is operated in order, and the user selects a desired course by operating the main selection unit 32. In this case, the controller of the washing apparatus may turn on the light emitting unit of the main selection unit 32 for a predetermined time, or repeatedly turn on / off at a predetermined period when the main selection unit 32 is dimmed.

On the other hand, when the main selector 32 is turned on in this way, only the main selector 32 is activated, and the remaining selector, that is, the subselector 34, may remain inactive. Here, 'activation' refers to a state in which the user can input the changed course information or step condition to the control unit by operating the selection unit, and 'deactivation' means course information even if the user operates each selection unit. It is a state in which the step conditions are not changed. This is because it is preferable to select the course by operating the main selection unit 32 and then change the respective step conditions by operating the sub selection unit 34.

Then, the user proceeds with the course selected by the step conditions stored by default in the controller for the selected course, for example, the washing step, the rinsing step, the dehydration step, or the drying steps, or at least one or more of the selected courses. You can proceed by changing the step conditions. First, when the washing process is to be performed according to each step condition stored by default for the selected course, the user may select the course by the main selecting unit 32 and then simply operate the start button 42 to proceed with the washing. . Next, the case where the user changes the step conditions in each step and proceeds will be described.

According to an exemplary embodiment of the present invention, when the user selects a desired course by manipulating the main selector 32, the controller selects a sub-selector 34, 35, 36, 37 according to an operation sequence, and then the user selects a course. Allows you to change step conditions at each step. Here, the 'operation sequence' may be implemented in various ways, but preferably follows the washing sequence. In this case, the light emitting part of the selected main selection part 32 is turned off to recognize that the user is not a selection object.

As described above, the sub-selectors 34, 35, 36, and 37 are provided to change at least one or more step conditions, for example, washing, rinsing, dehydrating, or drying. In FIG. 2, as an example, four sub-selectors 34, 35, 36, and 37 are provided. The sub-selectors 34, 35, 36, 37, for example, the water temperature in the washing step from the left side, the amount of water, the number of rinses in the rinsing step, the spin speed in the dehydration step, or the drying time in the drying step, etc. It can be provided to manipulate.

Meanwhile, most courses include a washing step, a rinsing step, and a dehydration step, but may include only a part of the above steps, and further, may further include a drying step in addition to the above steps. However, the sequence of general steps is carried out in the order of the drying step through the washing step, rinsing step, dehydration step. Therefore, when the user wants to manipulate the step conditions in at least one step of each step of the course selected by the user, the operation sequence is preferably made according to the order of the washing.

That is, the control unit turns off the light emitting unit of the main selecting unit 32, and then dims the sub-selecting unit 34 in the washing step according to the operation procedure. This allows the user to recognize that the conditions of the washing step can be manipulated. If desired, the user can operate the sub operation unit 34 of the washing step to adjust the step conditions of the washing step, for example, the temperature of water or the amount of water. Will be manipulated. In addition, the controller of the washing apparatus may turn on the light emitting unit of the sub-selecting unit 34 for a predetermined time when the sub-selecting unit 34 is dimmed or repeatedly turn on / off at a predetermined cycle.

On the other hand, when the sub-selector 34 of the washing step is turned on, only the on-selected sub-selector 34 is activated, and the remaining sub-selectors 35, 36, and 37 remain inactive. It is desirable to. In addition, in this case, the main selector 32 may not be emitted to maintain an inactive state, but the main selector 32 may continue to be activated. This is because the user may select a course by the main selection unit 32 and then change the course of the main selection unit 32 again in an operation step of the sub-selection unit.

As described above, when the sub-selection unit 34 of the washing step is illuminated and the user operates the sub-selecting unit 34 of the washing step, the control unit then selects the sub-selecting unit 35 of the subsequent step, for example, the rinsing step. The light emitting portion of is turned on. In this case, the light emitting portion of the sub-selecting portion 34 in the washing step is turned off. On the other hand, if the user does not operate the sub-control unit 34 of the washing step for a predetermined time when the sub-control unit 34 of the washing step is illuminated, it is determined that the user is not willing to change the conditions of the step The controller proceeds to the next step.

That is, the controller turns on the light emitting unit of the sub-control unit 35 in the rinsing step. At this time, the light emitting portion of the sub-selecting portion 35 in the rinsing step is continuously turned on or periodically turned on as described above. Further, when the sub-selection unit 35 in the rinsing step is dimmed, only the sub-selection unit 35 is activated, and the remaining sub-selection unit is also the same as described above.

Following the rinsing step, dimming the subselector 36 in the dehydration step or the subselector 37 in the drying step is similar to that described above, and thus repetitive description thereof will be omitted.

On the other hand, when the user selects the course by the main selection unit 32 and then selects the sub selection unit 34, 35, 36, 37 to change the previous step conditions, for example, dehydration step When the sub-selection unit 36 is dimmed, there are cases where it is desired to change the conditions of the washing step. In this case, the user may operate the main selector 32 again to fit the desired course, and thus operate the main selector 32 in the selection step of the sub selector 34, 35, 36, 37. Each step condition changed by the user is reset, and the user can operate the step conditions stored by default from the washing step again.

After inputting the desired course and / or desired step conditions through the above-described steps, the user operates the start button 42 to drive the washing machine, and the control unit selects the selected course and / or the selected step conditions. According to the driving of the washing machine.

On the other hand, even when the selection unit emits light according to the operation procedure by the above-described configuration and method, when the surroundings of the washing machine is too bright, such as during the day time, it may not be easy to identify the lighted selection unit and the non-emitting selection unit. In order to solve this problem, the present invention is provided with a configuration for easily identifying the light emitting selection unit, which will be described below with reference to the accompanying drawings.
