Description

laundry machine

The present invention relates to a washing machine, and to a washing machine having a convenient user interface. More specifically, the present invention relates to a washing machine that centralizes a user interface and provides a simple yet intuitive user interface.

A typical washing machine is a washing machine for washing clothes, and a dryer for drying clothes can also be called a washing machine. Of course, a washing machine and dryer capable of washing and drying clothes may also be referred to as washing machines.

Recently, a refresher that refreshes clothes using hot air or steam rather than washing with water has been released, and this can also be referred to as a washing machine.

Hereinafter, a washing machine is described as a representative example of a washing machine in the present specification, and as long as it is not exclusive and inconsistent with other devices, it may be applied to other washing 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 side of the washing machine so that the user can easily access and operate it. The control panel may be provided with an input unit or a selection unit such as various buttons for user manipulation, and various display units for providing information to the user. All of these various input units, selection units, and display units may be referred to as user interfaces.

The main function of a washing machine is washing. Accordingly, the course selection unit 110 or the main function selection unit for selecting various washing courses is provided, and the user selects the course through this. For example, the course selector 110 may be provided in the form of a rotary knob. A course display unit 111 may be provided on the control panel 100 to facilitate the user's course selection, and the user may select a desired washing course by manipulating 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.

1 shows a course display unit 111 displaying various washing courses around the rotary knob 110 , and a user can select a washing course corresponding to the rotation of the rotary knob 110 . A display unit 121 for displaying the selected washing course may be provided, through which the user can easily identify the selected washing course. That is, the user can easily recognize the selected washing course through the course display unit 111 and the corresponding blinking LED display unit 121 . The course display unit 111 may be provided in a printed form on the front surface of the control panel.

An option selection unit 120 capable of selecting an optional function to be added or changed in performing the above-described main function may be provided. The option selection unit 120 may be provided in various ways. 1 shows, as an example, an option input for selecting options related to washing (120a), rinsing (120b), dehydration (120c), water temperature (120d), drying (120e), steam (122), and reservation (123). An input unit 120 is shown. An option display unit 122 for displaying whether such an option is selected may also be provided, and similarly, may be implemented through an LED or the like.

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

For example, if the washing machine currently performs the rinsing step, it may be displayed as “in the rinsing step”. In addition, when waiting for the user to input the course, "Please input the washing course" may be displayed. In addition, the current time or the remaining time (remaining time) until the washing machine completes all the washing courses may be displayed.

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 or temporarily stopping the washing machine operation.

The above-described control panel 100 and a washing machine including the same have the following problems.

Due to a spatial problem of the control panel 100 , it is difficult to implement an additional user interface other than a configuration for a basic user interface. Of course, complex and various user interfaces may be implemented in the control panel 100 , but there is a problem that requires excessive concentration and prior knowledge for the user. In addition, there is a problem in that the washing machine itself becomes excessively expensive because it is difficult to manufacture the control panel 100 or requires a high-capacity memory.

In addition, since the respective functions of the selection units 110 , 120 and the display units 111 , 121 , and 122 are preset or set, there is a problem in that it is not easy to expand for additional functions. In addition, these various selection units 110 and 120 are exposed to the user as they are. That is, not only the necessary selection unit but also the unnecessary selection unit at a specific point in time are exposed to the user. Accordingly, there is a problem in that the various functions provided by the washing machine are not used if the user is not a skilled user.

In addition, since the number of the selection units 110 and 120 and the display units 111 , 121 , and 122 are large and scattered, the user interface is very inconvenient. That is, it is because the information input to the washing machine can be grasped only when the eyes are fixed on each of the components.

Recently, minimal design has been adopted a lot in the design of home appliances. In addition, the demand for a simple and intuitive user interface rather than a complex user interface is increasing. However, it is not easy to implement a simple and intuitive user interface in the washing machine. This is because it is necessary to provide a simple and intuitive user interface while including at least all of the user interfaces shown in FIG. 1 . In addition, it is necessary to allow a user familiar with the conventional user interface to adapt to the new user interface without too much difficulty.

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

Meanwhile, as shown in FIG. 1 , the number of courses basically provided by the washing machine is preset. For example, 12 washing courses are shown in FIG. 1 . Therefore, it is difficult to add a new laundry course, and even if it is added, the added course cannot but be selected through a separate option button or the like instead of through the course selection unit 110 . That is, the course is selected at the same level, but in some cases, the course must be selected through a selection unit other than the course selection unit 110 (for example, the shoe refresh course 124). There is a problem that it is not easy to use the added washing course.

An object of the present invention is to basically solve the above-mentioned problem.

An object of the present invention is to provide a washing machine having a simple and intuitive user interface.

It is an object of the present invention to provide a laundry apparatus that facilitates selection of a laundry course and an option associated with the selected laundry course. And, by visually showing the selected information to the user at the same time as selection, it is intended to provide a washing machine with improved ease of use.

Through one embodiment of the present invention, it is an object of the present invention to provide a washing machine capable of implementing a minimalist design by concentrating the user interface on a specific location without being scattered on the control panel.

An object of the present invention is to provide a washing machine capable of reducing the number of input units by having a single variable input unit.

Through an embodiment of the present invention, even if a new course is added, it is intended to provide a washing machine that can be easily checked and used.

An object of the present invention is to provide a washing machine capable of excluding or minimizing characters printed on a control panel or various input units through an embodiment of the present invention.

According to an embodiment of the present invention, it is an object of the present invention to provide a washing machine in which course selection and option selection are easy through the screen of the display.

Preferably, the controller determines that the input information displayed by the variable input unit is input when the single variable input unit is selected.

The plurality of input information may be distinguished from each other through a vertical arrangement or a left and right arrangement in a single variable input unit.

The single variable input unit may include: a plurality of light transmitting units respectively corresponding to the plurality of input information; a plurality of light sources corresponding to each of the plurality of light transmitting units; single touch unit; And it may include a single switch corresponding to the single touch unit. The light transmitting part may be formed in an icon shape. Accordingly, when light is emitted to the outside through the light transmitting unit, the user can easily visually recognize the icon shape. For example, a plurality of the icons may be provided in a vertical arrangement. In this case, when light is emitted through only one icon, the user can clearly understand input information corresponding to the icon from which the light is emitted.

The single touch unit may be spaced apart by a user's touch, and may be in the form of pressing the single switch through this. Thus, the single switch may be a tact switch.

Preferably, the control unit selectively controls the brightness of the plurality of light sources so that specific input information among a plurality of input information of the single variable input unit is recognized by the user. It is preferable that the positions of the plurality of input information are different from each other. Accordingly, it is preferable that the positions of the light sources corresponding to the respective input information are also different from each other. Of course, it is preferable that the plurality of input information are formed at different positions in the single variable input unit. Accordingly, due to the difference in brightness of the plurality of light sources, specific input information may appear visually more prominent than other input information.

The controller may control the brightness of the light source at two levels of maximum and minimum or three levels of maximum, intermediate, and minimum.

Preferably, the plurality of input information of the single variable input unit includes entering a reservation option when a specific laundry course screen is displayed on the display and completing option setting when the option screen is displayed on the display.

Preferably, when the single variable input unit is selected to enter the reservation option, the control unit controls the display to switch from the specific laundry course screen to an option screen for reservation setting.

Preferably, when the single variable input unit is selected to complete the option setting, the control unit controls the display to switch from the option screen for reservation setting to the specific laundry course screen.

The option may include at least one of a wash water temperature, a washing intensity, a number of rinsing times, and a spin-drying intensity, which is variably set within the specific washing course.

The option may include a reservation for delaying the end time of the specific washing course and variably setting the delay time.

The display area may include the single variable input unit.

The display area may include a plurality of option selection units provided on a one-to-one basis to individually select the temperature of the wash water, the washing intensity, the number of rinsing times, and the spin-drying intensity.

Preferably, the control unit controls the display to switch from the specific washing course screen to an option screen for changing the selected specific option when a specific option selection unit is selected among the option selection units.

The controller determines that the specific option is set when the single variable input unit is input when the information of the specific option is displayed on the option screen, and controls the display to switch from the option screen to the specific washing course screen This is preferable.

Each of the option selection units may include: a light transmitting unit; a light source corresponding to the light transmitting unit; And it may include a touch sensing unit. The light transmitting part may be formed in the shape of an icon. In other words, the light transmitting unit itself may have an icon shape. The light source may be an LED.

The controller may control the brightness of the light source to three levels of maximum, medium, and minimum.

For example, a course screen may require you to select a default option. Accordingly, in this case, the icon is visually displayed through the light transmitting unit of the option selection unit. Accordingly, the user can intuitively select the option selector on the course screen and can understand what kind of option it is.

You do not need to select a default option on the Reservation Options screen. Accordingly, it is preferable that the option selection unit related to the basic option selection is not visually displayed. That is, light is not transmitted through the light transmitting unit of the option selection unit. That is, this is because the light source is controlled to be Off. In other words, information related to the basic option is not exposed when it is impossible to select the basic option.

When a specific option selection unit is selected from among the plurality of option selection units, the LED corresponding to the selected option is preferably controlled to be brighter than the LED corresponding to the other option selection units. Accordingly, the user can easily visually identify the currently selected option or the option to be changed through the brightness control.

The display area may be formed to have the same black background screen. Such a display area may include a display, a single variable input unit, and an option selection unit. In addition, the display, the single variable input unit, and the option selection unit may be partitioned from each other.

and an annular decoration provided on the radially outer side of the rotary knob, wherein the decoration includes a plurality of icon-shaped light transmitting portions representing each washing course along the circumferential direction, and a plurality of light transmitting portions corresponding to each of the light transmitting portions. It is preferable that the light sources are provided.

An additional icon is provided in the decor, and the additional icon may correspond to a laundry course added to the laundry course provided by the washing machine. Of course, the additional icon may correspond to a washing course with a low frequency of use.

The decor may include a power input unit and a start/pause input unit.

The control unit controls the brightness of the light source, and when the specific course is selected through the rotary knob, the control unit controls the brightness of the light source corresponding to the specific washing course to be brighter than that of the light source corresponding to the other washing courses. desirable.

In the user interface of the washing machine according to an embodiment of the present invention, printing of characters corresponding to a specific language may be excluded. That is, it is preferable that the language for the user interface is not printed on the control panel. Such a language may be excluded and icons independent of the language may be provided.

On the other hand, the language displayed on the display may be variously modified. This is because it is a software problem, not a hardware problem. Accordingly, the user interface of the washing machine according to an embodiment of the present invention can be used flexibly in various languages without changing hardware.

The rotary knob assembly may include a rotary knob and an encoder. Since the display area is provided radially inside the rotary knob, it is difficult to directly connect the rotary knob and the encoder. Accordingly, in order to connect the rotary knob to the encoder, the rotary knob assembly may include a display mounting unit and an encoder mounting unit.

Preferably, the display mounting part is positioned at the rear of the rotary knob, and the encoder mounting part is positioned radially outside the display mounting part. Both can be connected to each other by gear meshing. Through this, the rotation of the rotary knob may be sequentially transmitted to the display mounting unit, the encoder mounting unit, and the encoder.

The rotary knob, the window forming the display area, the single touch unit of the single variable input unit, and the decoration may be exposed in front of the control panel. In addition, other components of the above-described rotary knob assembly may be located inside the control panel.

Accordingly, only a minimal user interface may be exposed on the front of the control panel or cabinet. Also, the exposed user interface is substantially centered on the rotary knob. Through this, concentration of the user interface and minimal design can be realized.

On the other hand, through an embodiment of the present invention, it is possible to maintain the sensitivity of the conventional rotary knob for selecting a course and a button for selecting a basic option.

In order to achieve the above object, according to an embodiment of the present invention, an annular rotary knob provided to select a washing course; a display for selectively displaying a course screen for the specific laundry course selected through the rotary knob and an option screen for changing an option for performing the specific laundry course; A washing machine comprising a single variable input unit having a plurality of input information and selectively displaying the plurality of input information, wherein both the display and the single variable input unit are located inside the rotary knob in a radial direction. have.

and a display area formed inside the rotary knob in a radial direction.

In the display area, the display and the single variable input unit may be positioned to be partitioned from each other.

The plurality of input information may be displayed by transmitting light from a plurality of light transmitting units formed at different positions on the front surface of the single variable input unit. Specifically, the user can intuitively grasp input information corresponding to the specific light transmitting unit by allowing light to be transmitted only through the specific light transmitting unit or to be transmitted brighter than light transmitted through other light transmitting units.

Meanwhile, the display area may include a basic option selection unit. The basic option selection unit may be provided separately from the display. The display may be provided only for the display, and the basic option selection unit may be provided so that a user can select it through a touch.

The basic option selection unit may be provided to select the temperature of the wash water, the washing intensity level, the number of times of rinsing, and the degree of spin-drying, respectively. Each of the basic option selection units may include a light transmitting unit.

Fig. 7 is a perspective view showing a relationship between the user interface of Fig. 2 and a control panel; and
FIG. 8 is an exploded perspective view of the user interface of FIG. 2 .

Hereinafter, a washing machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In particular, the user interface of the washing machine according to the present invention will be described in detail.

2 shows a user interface 300 of the washing machine according to an embodiment of the present invention. The user interface 300 may be provided in the control panel 200 of the washing machine (refer to FIG. 7 ) or in a cabinet forming the outer shape of the washing machine. Of course, the control panel 200 may be a part of a cabinet forming the outer appearance of the washing machine, or may be mounted on the cabinet.

As shown, according to the present embodiment, it is possible to provide a user interface 300 in which the conventional complex and various input units or selection units and displays are concentrated around the rotary knob 410 and a washing machine including the same.

That is, according to the present embodiment, unlike the conventional user interface shown in FIG. 1 , various input units or displays are not interspersed, and a user interface having a minimum number of input units centered on the rotary knob 410 can be implemented. In addition, it is possible to include substantially all of the conventional user interface functions or to easily add them through the user interface.

The washing machine according to the present embodiment may include a display area 430 provided on the radially inner side of the annular rotary knob 410 . The display area 430 may include a display 440 . The display 440 may be provided to display course information and option information.

The display 440 may be implemented as a liquid crystal display and may be implemented as an LCD, LED, or OLED display. Of course, it may be implemented as a touch display like the display of a smartphone.

However, when the display is implemented as a touch display, the production cost may increase excessively due to the display. In addition, since high performance of the processor constituting the control unit is required, the production cost may be excessively increased as well. Accordingly, it may be desirable to provide a liquid crystal display capable of displaying simple characters or figures.

Specifically, the display 440 may display information about a specific washing course selected through the rotary knob. A course screen and an option screen for changing options can be selectively displayed. Of course, the display 440 may display a guide screen (not shown) or a course progress screen (not shown) as well as a course screen and an option screen.

It is preferable that the washing machine according to the present embodiment provides a plurality of washing courses. The user selects a specific course from among a plurality of washing courses according to the purpose of washing or the type of laundry. 2 shows an example in which 10 laundry courses are basically provided. The number of such washing courses may be known through the number of icons 425 . And as will be described later, at least one new washing course may be added through the additional icon 427 .

The user may select a specific washing course from among a plurality of washing courses through the rotary knob 410 . When the user holds the rotary knob 410 and rotates it, the course selected in a preset order may be changed. The course selection through the rotary knob 410 is similar to that shown in FIG. 1 . Accordingly, a user who is accustomed to selecting a course through the rotary knob 410 can minimize the burden or difficulty of a new user interface.

When power is applied to the washing machine, an initial guidance screen may be displayed on the display 440 . For example, an initial guidance screen with the phrase “Please select a laundry course” may be displayed.

As the user rotates the rotary knob 410 to select a course, a plurality of washing courses may be sequentially displayed on the display 440 . The screen at this time may be referred to as a course screen. FIG. 2 shows a course screen providing information on a “standard laundry” course as an example of the course screen. When the user rotates the rotary knob 410 by one pitch more on the course screen of the standard laundry course, a course screen corresponding to the next course may be displayed on the display. Therefore, it can be said that the course displayed on the course screen is basically selected.

On the course screen, various information about the selected specific course as well as the course name may be displayed. As an example, as shown in FIG. 2 , information on power consumption, course execution time, and administration within the course may be displayed.

The user may intuitively check the selected course information through the display 440 provided inside the rotary knob 410 for selecting a course. That is, it is possible to easily check the selected course information without moving or dispersing the gaze.

Meanwhile, the language displayed on the display may be variously changed. That is, each language can be easily changed in software. In particular, the course name is determined according to each language, and even if the language is different, it can be easily dealt with without changing the hardware.

The control panel shown in FIG. 1 is provided with a course name printed on the front surface of the control panel. A washing machine manufactured by one washing machine manufacturer may be sold in many countries having various languages as well as in Korea. In this case, there is a problem that the hardware has to be changed according to each language. However, due to the radially inner side of the rotary knob 410 or the display surrounded by the rotary knob 410, it is possible to easily cope with a different language by software. This may mean that there is no need to create a control panel for each language.

In general, a washing course may include a washing cycle, a rinsing cycle, and a spin-drying cycle. Of course, at least one of the strokes may be omitted depending on the course. And according to the course, for example, the execution time of each stroke, the number of times, and the drum driving pattern may be preset differently.

In addition, each washing course has a basic set value. For example, the default settings of the standard washing course shown in FIG. 2 have a wash water temperature of 60° C., a standard washing intensity, 3 rinses, and strong dehydration. Such a basic setting value may be set differently for each course, and it is preferable that it can be changed. Of course, such changes may be limited to certain courses.

After selecting a specific course from among a plurality of washing courses, the user may select the start/pause input unit 421 . This form can be said to be the most basic use form of the washing machine. That is, when a start is input, the washing machine starts driving according to a selected specific course, sequentially performs preset strokes, and then ends the course.

As described above, various options may be selected for the washing course. That is, various options for changing a preset value or condition may be selected. Selection of these options may be performed on the premise of selection of a specific washing course.

Such an option may include at least one of changing the condition of each of the strokes included in the course, performing an additional administration, and changing the completion time of the course (reservation setting).

In general, the options may be provided to change the temperature of the wash water, the washing intensity, the number of rinsing times, and the spin-drying intensity. Each of these option changes may be performed by selecting any one of a plurality of values. These four options can be called basic options.

For example, the dewatering strength option may be provided to select any one of strong, medium and heavy. Of course, it may be provided to select any one by varying the rotation RPM of the drum from each other. The number of rinses option may be provided to select any one of the values of 5 steps from no rinse to 4 rinses.

Options may include reservation options. The reservation option may mean an option of delaying when a course ends. For example, when a specific course that takes 2 hours is selected, the time at which the course ends may be set to 4 hours after the present. In this case, the washing machine may have a standby time of 2 hours and may be terminated by performing the selected course for the remaining 2 hours. This reservation option is very useful if you are going out for a long time. That is, it is possible to set the washing to be finished according to the time of returning home. Therefore, it is possible to prevent the laundry from waiting for the end of washing or from being left in the washing machine for a long time.

In this embodiment, it is possible to provide a washing machine having a single variable input unit 460 in order to provide an intuitive and minimal user interface.

The single variable input unit 460 may be provided to select any one of the plurality of input information 461 and 462 according to a selection time. That is, one input unit may be provided to perform a plurality of functions. The single variable input unit 460 may be provided to be selected by a user separately from the rotary knob 410 . The single variable input unit 460 may be provided as a button selected by a user's touch or pressure.

Specifically, the single variable input unit 460 may have a plurality of input information and may be provided to selectively display the plurality of input information 461 and 462 . That is, it is preferable that the meaning of the selection of the single variable input unit 460 is visually displayed at the present time.

2 illustrates an example in which a clock-shaped icon 461 is displayed in the single variable input unit 460 . Through the clock-shaped icon, it can be seen that the input information is related to time and, more specifically, related to reservation. Accordingly, the user can intuitively grasp the input information of reservation by looking at the clock-shaped icon 461 .

For example, the user may select the single variable input unit 460 on the course screen of “standard laundry” shown in FIG. 2 . This can be said to be a direct reflection of the user's intention to delay the time when the standard washing course is performed and ended after selecting "standard washing".

When the input unit 460 displaying the reservation input information (ie, a clock icon) is selected, the display 440 switches from the course screen to the option screen. That is, an option screen for changing an option is displayed. At this time, it can be said that the single variable input unit 460 is provided for reservation entry. In addition, it can be said that the display is provided to selectively display a course screen and an option screen.

3 shows an example of an "option screen" for changing a reservation option. That is, when a single variable input unit 460 for displaying reservation information is selected on the course screen, the display displays an option screen for setting a reservation as shown in FIG. 3 . That is, the reservation option screen for changing the reservation time is displayed. In this case, the watch shape may be displayed and the current time may be displayed. In addition, a preset course name and completion time may be displayed. The completion time may mean how many hours after the current washing is finished. Assuming that the screen is switched from FIG. 2 to FIG. 3, it means that the standard course starts after a delay of 2 hours and 20 minutes from the present. And, it means that the standard course is performed for 1 hour and 10 minutes and ends after 3 hours and 30 minutes from the present.

Such reservation change or delay time change may be performed by turning the rotary knob 410 . That is, on the option screen other than the course screen, particularly the option screen for changing the reservation, the rotary knob 410 can be said to be a means for changing the reservation time. For example, as the rotary knob 410 is rotated clockwise by one pitch, the delay time may be increased by, for example, 10 minutes or 30 minutes. In the opposite direction, the delay time can be reduced by 10 minutes or 30 minutes in 1 pitch increments. Of course, it is preferable that the delay time setting range and unit are preset.

After the user determines the reservation time through the rotary knob 410 for example, the user may input the intention that the reservation setting has been completed through the single variable input unit 460 . That is, an input indicating that reservation setting has been completed may be input through the single variable input unit 460 . In this case, the single variable input unit 460 may be said to be provided to complete the reservation option setting, for example.

When the single variable input unit 460 is selected to complete the reservation option setting, the display switches from the option screen to the course screen again. Of course, the time information shown in FIG. 2 may be changed from 1 hour 10 minutes to 3 hours 30 minutes.

Accordingly, the single variable input unit 460 may be provided to selectively perform option entry for option change and option setting completion after option change. That is, in some cases, it is possible to select a plurality of inputs or functions through one input unit 460 . Through this, it is possible to prevent an increase in the number of input units. In addition, a time for selecting a course and a time for selecting an option after selecting a course may be distinguished to induce the user to make a necessary input. In addition, since the meaning of selecting the single variable input unit is visually displayed depending on the viewpoint, it is possible to prevent misunderstanding and confusion by the user. And, since such input information is displayed on the single variable input unit 460 itself, the user can more intuitively understand the meaning of selecting the input unit 460 .

Meanwhile, the division between the course selection time and the option selection time after course selection is the same as the division between the course screen display time and the option screen display time on the display, as described above.

For example, it is preferable to display the time icon 461 on the course screen and the OK display 462 on the option screen. The control unit may control the input information displayed on the single variable input unit to be different by dividing the screen displayed on the display.

That is, it is preferable that the control unit controls so that input information corresponding to each course screen is displayed on the single variable input unit. In addition, when the single variable input unit 460 is selected, the controller preferably determines that the input information displayed in the single variable input unit is input. For example, when the single variable input unit 460 is input while the reservation option entry information is displayed, the controller controls the display to display an option screen for changing the reservation option. And, when the single variable input unit 460 is input while the setting completion information is displayed, the controller controls the display to display the course screen. Of course, it is preferable that the course screen at this time be a course screen in which the changed option is reflected.

As shown in FIGS. 2 and 3 , two icons 461 and 462 may be vertically disposed in one single variable input unit 460 . Of course, it may be arranged left and right. In addition, the two icons may be selectively displayed.

The selective display of such a plurality of input information may be implemented through the control of the light source. For example, it can be implemented through the brightness control of the LED. Details on this will be described later.

Meanwhile, the single variable input unit 460 is preferably provided inside the rotary knob 410 in a radial direction. That is, the display area 430 preferably includes a single variable input unit 460 as well as the display 440 . Accordingly, the movement of the user's gaze is minimized and intuitive input is possible at the same time.

As described above, the options may include basic options as well as reservation options. In other words, it is possible to change the default options within a particular laundry course. Option selection units 471 to 474 may be provided to change these basic options. FIG. 2 shows four basic option selection units, and the number of these basic options may vary. The option selection units 471 to 474 may be implemented in the same or similar button shape as the single variable input unit 460 . This will be described later.

In the course screen shown in FIG. 2 , for example, the user may select the option selector 473 corresponding to the rinsing option in order to change the rinsing option. The selection of the option selection unit 473 may be performed by the user pressing or touching the option selection unit 473 . When the rinsing option selection unit 473 is selected, an option screen for changing the rinsing option is displayed on the display 440 . That is, when the rinsing option selection unit 473 is input, the controller controls the display 440 to display a corresponding option screen. 4 shows an example of an option screen for changing a rinse option.

On the screen shown in FIG. 4 , the user may select a desired rinsing option. That is, the number of rinsing times different from the preset number of rinsing may be selected. For example, the basic setting of 3 rinse times may be set to 2 times.

Changing the number of rinsing may be performed through the rotary knob 410 . As the rotary knob 410 is turned, the number of rinsing times may be sequentially changed. For example, when changing the number of rinsing times from 3 times to 2 times, the rotary knob 410 may be rotated counterclockwise by one pitch.

Also, changing the number of rinsing may be performed by pressing the rinsing option selection unit 473 . Whenever the user presses the rinse option selection unit 473 , the number of times of rinsing may be sequentially changed.

After changing the number of rinses, the user may input a single variable input unit 460 on the screen shown in FIG. 4 . That is, completion of selection of a specific number of rinsing may be performed by inputting the single variable input unit 460 . At this time, it is preferable that the single variable input unit 460 displays OK information as an example similar to the completion of the above-described reservation option setting. That is, it is preferable to display OK information indicating completion of the rinsing option setting.

Accordingly, on the option screen for changing the option, it is preferable that the single variable input unit display input information indicating that the option setting has been completed. This is preferably the same for other options, such as wash water temperature, washing strength and spin-drying strength.

4 shows an option screen for changing rinsing options. Accordingly, it is preferable that the rinsing option selection unit 473 is displayed brighter than the other option selection units 471 , 472 , and 474 . Of course, it may not be possible to select an option on the reservation setting screen as shown in FIG. 2 . Therefore, it is preferable that such selection units 471 to 474 are not displayed on the reservation setting screen.

Meanwhile, as described above, it can be seen that both the selection of the washing course and the selection of options can be performed in the rotary knob 410 and the display area 430 . That is, the user's hand and gaze for the user interface can be focused on a specific area without being dispersed, so that it is convenient to use.

That is, since the operation of the rotary knob 410 and the screen by the display inside the rotary knob are changed immediately, the user interface can be performed very easily. In addition, selection and change of options and completion of option setting may be performed on a display area inside the rotary knob 410 . Due to this, the user interface can be performed very easily.

Meanwhile, a course display unit 121 is provided on the radially outer side of the rotary knob 110 shown in FIG. 1 . Accordingly, as the rotary knob 110 is rotated, the position of the light-emitting course display unit is changed. For the convenience of a user familiar with such a user interface, a similar annular deco 420 and an icon 425 provided in the deco may be provided in this embodiment as well. A plurality of the icons 425 may be formed to correspond to a course provided by default.

The icon 425 may be formed to intuitively represent each washing course in the form of a figure or a picture. Since the icon 425 is not a language, it may not be affected as the language changes. In other words, it can be said that it is very effective for a minimal design because it is independent of the language of the place where the washing machine is sold.

The icon 425 may be referred to as an auxiliary means for facilitating course selection. In this embodiment, information on a specific washing course selected as a premise in a process of changing an option, etc. may be visually displayed to the user through the icon 425 .

Meanwhile, the decor 420 may include an additional icon 427 as well as an icon representing each washing course. The additional icon 427 may correspond to a laundry course added to the laundry course provided by the washing machine.

As the materials of clothing diversify and the frequency of use of functional clothing increases, it is necessary to provide a new laundry course. In this case, a new washing course must be added to the washing machine, and it is not easy to change the conventional user interface.

When a new laundry course is added, there is a problem that such information cannot be easily exposed to the user. Therefore, there is also a problem that the addition of a new washing course is not attempted.

In order to solve this problem, in an embodiment of the present invention, the user can easily check and use the added laundry course through an additional icon instead of a text.

In addition, there may be a washing course with a very low frequency of use among the washing courses provided in the prior art. Infrequently used laundry courses do not always need to be exposed to users. However, it may be undesirable to exclude washing courses with low frequency of use. Accordingly, it becomes possible to associate a washing course with a low frequency of use to the additional icon 427 . Through this, it is possible to prevent the number of icons 425 from being lowered due to excessive number of icons 425 .

In other words, it can be said that the additional icon 427 corresponds to a washing course newly added in addition to the basic washing course and/or to a basic washing course having a low frequency in addition to a basic washing course having a high frequency of use.

For example, when the user turns the rotary knob 410, each basic icon is sequentially displayed brighter. Thereafter, when the rotary knob 410 is further turned, the additional icon is displayed more brightly. In this case, the course corresponding to the additional icon is displayed on the display 440 .

In the case of three new courses, the additional icon may still be displayed brighter until the rotary knob 410 is turned two pitches. Of course, when the rotary knob 410 is turned by one pitch, a new course corresponding to this will be displayed on the display.

5 shows a swimsuit course as an example of the new course added. Accordingly, the user can easily use a new course added through the additional icon. This may mean that no hardware changes are required for the user interface. Accordingly, it is very easy to add, select, and use a new course while maintaining the conventional course selection method.

Meanwhile, the bathing suit course may be a course provided by default. The frequency of use of the course for washing the wetsuit may be very low. Accordingly, it is also possible to associate a course with such a low frequency of use to the additional icon 427 . Through this, it is possible to prevent the washing course with low frequency of use from being always exposed to the user.

6 shows a swimsuit course as an example of a new course added. In this case, unlike in FIG. 5 , a text describing the course rather than the course name may be displayed. Of course, the screens shown in FIGS. 5 and 6 may be alternately displayed. On the other hand, in the case of an added course, it may be clearly displayed on the display 440 . 5 and 6 show examples of clearly indicating that the course is added through the phrase “NEW”.

As described above, the icon 425 provided in the decor 420 may be an additional means for facilitating course selection. Therefore, it is preferable that the icon corresponding to the selected washing course is visually different from other icons.

FIG. 2 shows an example in which the icon corresponding to the "standard laundry" course is displayed more outwardly than other icons.

In general, when power is applied to the washing machine, a washing course is selected first. Therefore, it is preferable that all icons corresponding to the plurality of washing courses are displayed with the same brightness first when power is applied. In addition, as the rotary knob 410 is rotated, it is preferable that only the icon corresponding to the corresponding washing course is displayed more brightly.

Accordingly, it is preferable that the brightness level of the additional icon 427 as well as the icon 425 is controlled in plurality. For example, it can be controlled to the lowest level (or OFF state), the middle level, and the highest level.

It may be the lowest level in a state in which power is not applied and in a state in which a washing course cannot be selected. It may be an intermediate level in a state that can be selected as a laundry course. And, it may be the highest level in the state selected as the washing course.

In FIG. 2 , since the standard washing course is selected, the icon for the standard washing course is the highest level, and the remaining icons are at the intermediate level. That is, in this state, it means that the washing course can be changed. Accordingly, it is possible to intuitively recognize the current state through the difference in the brightness level of the icons.

3 and 4 each show an example in which a reservation option change and a rinsing option change are performed on the premise that a standard washing course is selected. Since this option change already presupposes the selection of the standard laundry course, it is impossible to change the course at this point. Accordingly, the icons for the standard laundry course appear at the highest level and the remaining icons appear at the lowest level. Accordingly, the user can clearly grasp the precedence relationship between course selection and option selection.

The icons 425 and 427 may be implemented through the light transmitting unit 426 . Similarly, the above-described input information of the single variable input unit may be implemented through the light transmitting unit.

As shown in FIG. 2 , the decor 420 may include a power input unit 422 and a start/pause input unit 421 . The input units 421 and 422 may be provided in the form of a button. The positions of the input units 421 and 422 mean that substantially all of the user interface 300 can be focused on the rotary knob 410 . Icons representing the input units 421 and 422 may also be implemented through the light transmitting unit.

Meanwhile, the display area 430 preferably includes a display 440 , option selection units 471 to 474 , and a single variable input unit 460 . That is, it is preferable that the display area 430 is divided into a plurality.

Accordingly, it can be said that the radially inner circle region of the rotary knob 410 is divided into the display 440 , the option selection units 471 to 474 , and the single variable input unit 460 . Also, when a rectangular display is used, the display area 430 may further include a dummy area 450 .

Preferably, the display area 430 has a background screen of the same color. For example, it is preferable to have a black background screen. That is, the entire radially inner side of the rotary knob 410 may be implemented as a single black display. Of course, in reality, it is preferable that only a part is a display. Accordingly, it is possible to implement a feeling of satisfaction and design as if using a touch display without having an expensive touch display.

Such a black display effect may be more conspicuous through the above-described light transmitting units. This is because light is not transmitted through the light transmitting unit in a state in which power is not applied. That is, it is because all the icons shown in FIG. 2 may appear as if they have disappeared. That is, light is not transmitted through the light transmitting unit corresponding to the option selection units 471 to 474 and the light transmitting unit corresponding to the single variable input unit 460 . Also, the display 440 is turned off. Accordingly, the display area can be viewed as if it were a black display. Also, no light is transmitted through the light transmitting unit 426 corresponding to the washing course icons 425 and 427 . Through this, it is possible to realize a minimal design without text or language printed on the front of the control panel.

Hereinafter, an embodiment of the structure of the aforementioned user interface 300 will be described in detail with reference to FIGS. 7 and 8 .

7 illustrates a positional relationship between the control panel 200 and the user interface 300 . The rotary knob 410 and the decor 420 are exposed on the front surface of the control panel 200 , and the remaining components may be located inside the control panel 200 . In addition, the display area 430 is exposed from the front of the control panel 200 so that the user can access it.

The rotary knob 410 is rotatably provided, and the display area 430 provided radially inside the rotary knob 410 does not rotate.

The rotation of the rotary knob 410 is transmitted to the display mounting unit 436 , and the rotation of the display mounting unit 436 is again transmitted to the encoder mounting unit 437 . Due to the rotation of the encoder mounting part 437, the encoder 439 is rotated. The rotation signal of the encoder 439 is transmitted to the controller 435 . The control unit may be implemented through a controller mounted on a PCB.

A display 440 may be positioned inside the display mounting part 436 in a radial direction. Although the display mounting part 436 rotates, it is preferable that the display 440 is fixed so as not to rotate. That is, it can be said that the rotary knob 410 and the display mounting unit 436 are rotatably provided with respect to the display area 430 . For this reason, it is difficult to position the encoder 439 behind the rotary knob 410 . Accordingly, in order to transmit the rotation of the rotary knob 410 to the encoder 439 , it is preferable to position the encoder mounting unit 437 radially outside the display mounting unit 436 .

The display mounting part 436 and the encoder mounting part 437 may be provided to be engaged with each other in the form of a gear. This allows rotation to be transmitted.

FIG. 8 is an exploded perspective view of the user interface 300 shown in FIG. 7 .

A part of the rotary knob 410 may be inserted into the radially inner side of the decor 420 to be connected to the display mounting unit 436 . A window 431 and a single touch unit 462a of the single variable input unit 462 are positioned on the front surface of the display area 430 .

The input unit housing 432 and the LED PCB 433 may be positioned behind the window 431 and the single touch unit 462 .

The input unit housing 432 may be equipped with four touch sensing units 471a corresponding to the option input units 471 to 474 and a tact switch 462b corresponding to the single touch unit 462a.

The LED PCB 433 may include a plurality of LEDs 471b as light sources corresponding to the option input units 471 to 474, respectively, and a plurality of LEDs 462c and 462d corresponding to the single touch unit 462. have.

Four LEDs 471b may be provided to correspond to the four basic options, respectively, and their brightness may be controlled differently. Likewise, the LEDs 462c and 462d may have their brightness controlled differently to selectively display input information from a single variable input 462 .

A main PCB constituting the control unit 435 may be provided at the rear of the decor 420 , and a plurality of LEDs 425a corresponding to each washing course may be provided on the main PCB. In addition, an LED supporter 434 may be positioned between the LED 425a and the decor 420 .

Meanwhile, the window 431, the single touch unit 462a of the single variable input unit, and the deco 420 are formed with a light transmitting unit. The light transmitting unit itself may be in the form of an icon. That is, light may be substantially transmitted only through the icon-shaped portion. Accordingly, it is possible to visually display the current state by differently controlling the brightness of the light transmitted through the icon.

These light-transmitting units may correspond to each light source. Of course, the light source may be an LED. Preferably, the controller 435 selectively controls the brightness of these light sources. This level of brightness may be performed in three stages as described above. In addition, brightness control may be implemented through on/off control or duty ratio control for a plurality of LEDs.

The control of the light source, particularly the LED, is to show information displayed through the light transmitting unit in a timely manner. That is, in a state where selection or input is required or possible, light is transmitted through the light transmitting unit to show that selection and input are possible. In addition, it can be shown that any selection and input is possible due to the icon shape of the light transmitting unit. On the other hand, in a state where selection or input is unnecessary or impossible, light is not transmitted. Accordingly, it is possible to effectively prevent the user from being misunderstood by exposing such information.

In particular, in the present embodiment, since one input unit selectively shows which inputs are possible according to the current state, it is possible to effectively prevent a reduction in the number of input units, user convenience, and user's misunderstanding and confusion.
