6 schematically illustrates an example of various types of display modes displayed on the display window 120 by the display controller 250.

As shown, the display mode implemented by the display means 256 is a standby mode 300 depicting a waiting state before the air conditioning function is largely executed, and an operation mode indicating that the air conditioning function is being performed. And a function selection mode 340 for selecting various functions.

The standby mode 300 includes a screen off mode 302 in which nothing is displayed on the screen, a clock mode 304 for displaying a current time, a screen save mode 306 in which a screen saver program is executed, and a user set It is common for at least one of the user setting modes 308 in which any image is displayed to be configured to be displayed.

That is, one of the above screen off mode 302, clock mode 304, screen protect mode 306, and user setting mode 308 is generally set when the air conditioner is released. Therefore, when the user applies power to the air conditioner, the set standby mode 300 is booted and displayed.

Of course, the standby mode 300 may be changed by a user. That is, the user selects a desired mode from the screen off mode 302, the clock mode 304, the screen saver mode 306, and the user setting mode 308. It is also possible to be implemented in the display window 120 through.

In more detail, the screen off mode 302 means that the display window 120 remains off.

In the watch mode 304, a current time is displayed on the display window 120, and a year and month are displayed together with the time, and a value measured from a temperature sensor or a humidity sensor may be simultaneously displayed.

In the screen save mode 306, a preset screen save program is executed, which means that a screen saver, also called a screen save, is operated. Therefore, the screen saver mode 306 is the same as the screen on which the screen saver widely used in the computer is executed.

The user setting mode 308 allows the user to display an image which has been arbitrarily preset. That is, the user arbitrarily presets a picture of himself or his family or his character, and this set image is displayed when the power is applied.

The operation mode 320 refers to a state of an image implemented through the display means 256 when an air conditioner is operated by inputting the operation / stop key 132 in the standby mode 300. The driving mode 320 is divided into a live driving mode 322, a user driving mode 324, and a character driving mode 326.

Therefore, when the air conditioner operates, any one of the real operation mode 322, the user operation mode 324, and the character operation mode 326 constituting the operation mode 320 is executed. That is, any one mode preset by the user is executed.

In the live operation mode 322, a real image (picture) previously stored in the main memory 202 or the display memory 252 is displayed. The real image may be a still image or a moving image.

The user operation mode 324 uploads an image or a video that a user desires to the display memory 252, and then selects the uploaded image or video by the user and the display window 120 when the air conditioner is operated. ).

The character driving mode 326 is a mode for displaying a character stored in advance, such a character may be composed of a still image, or may be made of a dynamic character. For example, when the character driving mode 326 is executed, a skiing character may be implemented in the display window 120, and such a character is preferably displayed as a video.

On the other hand, the operation mode 320 as described above is continuously operated unless a separate key (Key) for executing another command is input. When the air conditioner is stopped in the operation mode 320, the air conditioner returns to the standby mode 300. At this time, the automatic cleaning 310 may be performed. However, this automatic cleaning 310 function is executed only when the function is set in advance.

In addition, the driving mode 320 may be configured to switch to the screen protection mode 306 according to the user's setting. That is, after the operation mode 320 is executed, if no execution key is input by a predetermined time, a pre-stored screen saver program is executed to switch to the screen saver mode 306.

In the screen protection mode 306 as described above, when an arbitrary key is inputted, the screen protection mode 306 is automatically terminated and returned to its original state. That is, the operation returns to the operation mode 320 again.

The function selection mode 340 is a mode for allowing a user to select or set various functions of the air conditioner.

The function selection mode 340 includes a driving / additional function 342 and an album function 344.

The operation / additional function 342 is to set an operation state and an additional function of the air conditioner, and the album function 344 allows to store and edit various pictures.

In the operation function, it is possible to select a state of use of an air conditioner such as cooling or dehumidification and to adjust the air volume.

Meanwhile, the pop-up function 360 may be additionally performed during each of the above modes. The pop-up function 360 means that various pop-up windows are displayed on the display window 120 so that a user can visually easily recognize an error state of an air conditioner or an operation state of an input key while executing each mode. .

The function selection mode 340 may also be configured to switch to the screen protection mode 306 as in the operation mode 320 according to the user's setting. That is, after the function selection mode 340 is executed, if no execution key is input by the preset time, the pre-stored screen saver program is executed to switch to the screen saver mode 306.

Hereinafter, an execution process of each mode having the above configuration will be described with reference to FIG. 7. FIG. 7 is a flowchart illustrating a schematic flow of the standby mode 300, the operation mode 320, and the function selection mode 340.

As shown, first, the display controller 250 determines whether power is supplied (S400). When the power is supplied, the 'preparation step' is executed (S402), and if no power is supplied, no action is taken.

The 'preparation step' is a step in which the display means 256 establishes a display environment when power is supplied from the outside. That is, the display means 256 is a process of starting up the display means 256 so as to be operable according to the command of the display control unit 250 to establish an initial setting. Each process of this 'preparation stage' is described in detail below.

After the above 'preparation step' is executed (S402), the standby mode 300 is successively executed (S410). When the standby mode 300 is executed, the screen off mode 302, the clock mode 304, the screen save mode 306, or the user setting mode 308 as described above may alternatively be displayed. do.

Next, it is determined whether the operation / stop key 132 is input (S420). In this case, when the operation / stop key 132 is input, the signal is transmitted to the main controller 200 to operate an air conditioner (S421). That is, the main control unit 200 operates the air conditioning components such as the indoor motor 216 and the outdoor motor 218 to perform air conditioning of the indoor space (S421).

On the other hand, when the operation / stop key 132 is not input, it is also determined whether the plasma key 137 is input again (S430). When the plasma key 137 is input, the input signal is transmitted to the main controller 200 to operate the air purifier 170. Therefore, the air cleaning function is executed (S432).

The air purifier 170 operates to determine whether an end key is input while the air cleaning function is performed (S434), and when the end key is input, such a signal is transmitted to the main controller 200 to provide an air purifier. 170 is stopped (S436). In this case, the end key means an input of the plasma key 137. That is, when the plasma key 137 is pressed once, the air purifier 170 is operated, and when the plasma key 137 is pressed again in this state, the air purifier 170 is stopped.

When the air conditioning function is executed as described above (S421), the operation mode 320 is executed on the display window 120 (S440).

When the driving mode is executed (S440), the display memory 252 sets a time. That is, the time 'T = 0' is set (S460). In addition, it is determined whether a function key such as the left key 138 or the right key 139 is input through the button unit 130.

As a result of the determination, when the function key is input (S462), the function selection mode 340 is executed (S480). Otherwise, it is determined whether the operation / stop key 132 is input again (S464). .

When the operation / stop key 132 is not input, the time value T stored in the display memory 252 is read (S466). Then, it is determined whether the time value T is equal to or greater than the time set value (eg, 5 minutes) set in the above environment setting (S468).

If it is determined that the time value T is equal to or greater than the time set value, the screen protection mode 306 is executed (S470). The screen protection mode 306 terminates when an arbitrary key is input (S472).

When the function selection mode is executed (S480), the display memory 252 resets the time. That is, time is set to 'T = 0' (S530). Then, it is determined whether the right key 139 (here, used as a function closing key) is input through the button unit 130 (S532).

When the 'function close key', that is, the right key 139 is input, the screen returns to the operation mode execution screen, and when it is not input, it is determined whether the operation / stop key 132 is input again. (S534).

In this case, when the operation / stop key 132 is not input, the time value T stored in the display memory 252 is read (S536). Then, it is determined whether the time value T is equal to or greater than the time set value (eg, 5 minutes) set in the above environment setting (S538).

If it is determined that the time value T is equal to or greater than the time setting value, the screen protection mode 306 is executed (S540). The screen protection mode 306 determines whether an arbitrary key is input (S542), and when the key is input, the screen protection mode 306 ends (S544).

Meanwhile, as a result of determining whether the operation / stop key 132 is input in steps S464 and S534, when the operation / stop key 132 is input, the main controller 200 stops the air conditioner. Let's do it. That is, execution of the air conditioning function is stopped (S550).

Then, the air conditioner is stopped and at the same time automatic cleaning is performed (S552). Of course, this function is performed when it is set in advance.

Then, it is determined whether the power is cut off (S560), and when the power is cut off, all display execution is terminated (S570), and when the power is not cut off, the display returns to the standby mode execution screen. .

8 illustrates the execution of the 'preparation step' described above in more detail.

As shown therein, the 'preparation step' includes a booting process (S403) for invoking an operating system (Operating System) so that the display means 256 can operate, and a loading for loading data from memory. A process S404 and a screen display process S405 for displaying that the loading process is performed are performed.

The booting process S403 is an operation of preparing an operation by invoking an operating system so that the display means 256 can operate. That is, when power is applied to the display means 256 and the display control unit 250, a booting program is first executed to bring an operating system into the main memory of the display control unit 250 to display the display means 256. Be prepared to work.

The loading process S404 is a process of reading various data from the memory.

In more detail, various data such as text data, image (video) data, avatar (character) data, and the like are read from the display memory 252, the main memory 202, or the auxiliary memory (a secondary memory device, a bootable device). Loading of the main memory of the display controller 250 is performed.

In the screen display process (S405), the display is displayed to the outside through the display means 256 so that the user can visually recognize that the loading is in the outside.

More specifically, a text (text), an image (image), or an avatar (character) indicating that the loading process S404 is being executed is displayed on the display means 256 so that the user can easily recognize the text. It is a process.

When the screen display process (S405) is performed, as shown in the display control unit 250 determines whether the boot is complete (S406). As a result of the determination, when the booting is completed, the standby mode 300 is executed. Otherwise, the screen display process (S405) is performed as it is, and it is continuously determined whether the booting is completed (S406).

9A to 9C illustrate examples of screens displayed on the display means 256 by the screen display process S405.

As shown in FIG. 9A, text data is read from a memory through a loading process S404, and the text data is displayed through the display means 256 and is currently being loaded.

9B shows that image (image) data is read from the memory through the loading process (S404), and the image (image) is displayed through the display means 256 and is currently being loaded. That is, a state in which the actual photographic image is displayed is shown.

FIG. 9C is a screen showing that the avatar (character) data is read from the memory through the loading process (S404), and the avatar (character) is displayed by the display means 256 and is currently being loaded. .

Meanwhile, in the 'preparation step' as described above, a screen displayed through the display means 256 may be used in various ways other than the above-described method.

For example, as described above, the text (text), image (video), or avatar (character) indicating that the loading process S404 is being executed is displayed in a dynamic state in addition to being displayed in a static state. Can be configured. That is, it may be configured to change the displayed text (Text), image (video) or avatar (character) according to the loading progress state.

In more detail, as shown in FIG. 9A, in addition to displaying static text, the text is moved left and right or up and down, or the content of the text is continuously changed according to the loading progress state. Can be. In other words, the text may be moved or different text may be displayed according to the loading progress state.

In addition, as shown in FIG. 9B, a static image (video) is displayed and a video is displayed, or a plurality of images (video) are sequentially or randomly loaded according to a loading progress. It may be configured to display.

In addition, a static character (avatar) is displayed as shown in FIG. 9C, and a dynamic character (avatar), that is, a moving character (avatar) is configured to display, or a plurality of characters (avatars) are loaded. ) May be sequentially or randomly displayed according to the progress rate.
