Best Mode for Carrying Out the Invention [61] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. [62] FlG. 2 shows the appearance of an indoor unit of an air-conditioner according to the present invention. [63] Referring to FlG. 2, the air-conditioner includes an indoor unit 100 and an outdoor unit (not shown). A front panel 110 is located at the front of the indoor unit 100. The front panel 110 is configured in the form of a vertically-elongated shape, such that it acts as a front frame of the indoor unit 100. [64] A hinge 112 is located at right upper/lower ends of the front panel 110, such that it serves as a rotation center of the front panel 110. Therefore, the front panel 110 rotates in a counterclockwise direction on the basis of a right end of the front panel 110, such that it can be opened from the indoor unit 100. [65] A display window 120 is located at the center of an upper part of the front panel

110. The display window 120 displays at least one avatar. Preferably, the display window 120 may be implemented with a Liquid Crystal Display (LCD), etc. [66] A button unit 130 is located under the display window 120. The button unit 130 includes a plurality of operation buttons such as a power-supply button, such that a user can easily adjust a variety of operations of the air-conditioner.

[67] A remote-controller receiver 140 is located under the button unit 130. The remote- controller receiver 140 receives signals from the remote-controller. [68] FlG. 3 is a perspective view illustrating an open state of the front panel 110 of the indoor unit 100 of the air-conditioner. As can be seen from FlG. 3, the front panel 110 rotates around an axis of the hinge 112, such that it is opened from the indoor unit. [69] A display unit 150 is located at a back surface of the front panel 110. The display unit 150 includes a variety of electronic components to control a variety of avatars

(images) to be displayed on the display window 120. [70] The display unit 150 further includes a Universal Serial Bus (USB) mounting unit

152. A USB memory 160 is selectively mounted to the USB mounting unit 152.

Therefore, the display unit 150 can easily receive external data via the USB memory

160. [71] Needless to say, data can be downloaded from the USB memory 160 or a variety of mobile recording mediums, or can also be transmitted to a destination via the USB memory 160 or the mobile recording mediums. Likewise, the display unit 150 may download data via the Internet if required. [72] For example, data can also be transmitted to a destination via an IEEE 1394 port instead of the USB memory 160. [73] The display unit 150 further includes a speaker 162. The speaker 162 is used as an example of the sound output unit 222, and outputs music or melody sound. [74] In the meantime, an air-cleaning unit 170 for filtering impurities or alien substances from the air so as to clean the air is located at an inner lower part of the indoor unit 100. A plurality of filters are located at the air-cleaning unit 170, such that a variety of impurities (e.g., dust or unpleasant odorous particles, etc.) are filtered by the filters of the air-cleaning unit 170.

[75] A plurality of components (e.g., a heat-exchanger) (not shown) for air-conditioning functions (e.g., a cooling function and a heating function) are contained in the indoor unit 100. Functions and configurations of the above-mentioned components are well known to those skilled in the art, such that it will herein be omitted for the convenience of description.

[76] FIG. 4 is a front view illustrating a detailed configuration of a button unit mounted to a front panel of an indoor unit of the air-conditioner according to the present invention.

[77] A detailed configuration of the button unit 130 is depicted in FIG. 4. Individual keys contained in the button unit 130 may be implemented in various ways, for example, a press-button scheme or a touch-screen scheme, etc.

[78] An operation/stop button (or key) 132 is located at the center of the button unit 130.

[79] The operation/stop key 132 is adapted to perform or stop an air-conditioning function of the air-conditioner. In more detail, the operation/stop key 132 is used as a key for powering on the air-conditioner when the air-conditioning function of the air- conditioner has stopped its operation. The operation/stop key 132 is used as a key for powering off the air-conditioner when the air-conditioning function of the air- conditioner is being performed.

[80] The air-conditioner according to the present invention further includes an additional function such as an air-conditioning function. Generally, the air-conditioner mainly performs the air-conditioning function to cool/heat room air via a heat-exchanging operation. A first case in which the air-conditioning function of the air-conditioner is executed is called an "Operation". A second case in which the air-conditioning function of the air-conditioner is not executed is called a "Stop".

[81] Two temperature keys 134 are located above or below the operation/stop key 132.

[82] Each temperature key 134 acts as a button for setting a temperature state. The upper temperature button acts as a button for increasing a temperature, and the lower temperature button acts as a button for reducing the temperature.

[83] The temperature key 134 is not operated while the air-conditioner has stopped its operation. Specifically, the temperature key 134 is used as a key for increasing/ reducing the temperature during an operation mode (e.g., a character operation mode), but it should be noted that the temperature key 134 is used as an up/down movement key during a specific function selection mode (e.g., an album function).

[84] In the meantime, two volume keys 135 are located at right and left sides of the operation/stop key 132, respectively, and adjust the volume of sound. In other words, the volume keys 135 adjust the volume of sound outputted via a speaker (not shown) contained in the indoor unit 100 of the air-conditioner. The left volume key 135 acts as a button for reducing the volume of sound, and the right volume key 135 acts as a button for increasing the volume of sound. The volume key 135 also acts as a right/left movement key such as the temperature key 134.

[85] A wind- volume key 136 is located at a left lower end of the button unit 130. The wind- volume key 136 is used as a key for setting the volume of wind generated from the air-conditioner. The wind- volume key 136 is operated only when the air- conditioner is operated, and is not operated when the air-conditioner has stopped its operation.

[86] A plasma key 137 is located at a right lower end of the button unit 130. The plasma key 137 is used as a key for operating the air-cleaning unit 170 contained in the air- conditioner. The plasma key 137 is designed to be operated during an operation mode or stop mode of the air-conditioner.

[87] Therefore, the air-cleaning unit 170 performs the air-conditioning function of the air-conditioner, and at the same time cleans air. Also, the air-cleaning unit 170 can operate alone even though the air-conditioner is in the stop mode, such that it cleans room air.

[88] A left key 138 is located at a left upper end of the button unit 130, and a right key

139 is located at a right upper end of the button unit 130.

[89] If the air-conditioner is in the stop mode, the left key 138 and the right key 139 are not operated. If the air-conditioner is in the operation mode, the left key 138 and the right key 139 are adapted to select a variety of menus from among the following function selection modes.

[90] A system for controlling the air-conditioner according to the present invention will hereinafter be described with reference to FlG. 5.

[91] FlG. 5 is a block diagram illustrating a control system of the air-conditioner according to the present invention. Detailed block diagrams of the indoor unit 100 and the display unit 150 are shown in FlG. 5. As can be seen from FlG. 5, the main controller 200 and the display controller 250 are installed independently of each other.

[92] Needless to say, it should be noted that the following preferred embodiments of the present invention is also applicable to a control system shown in FlG. 6. Therefore, besides the control system of FlG. 5, if there is a need to explain the control system of FlG. 6, detailed operations of the control system of FlG. 6 will be additionally described at a later time.

[93] Referring to FlG. 5, the indoor unit 100 for use in the air-conditioner includes the main controller 200 for controlling overall operations of the air-conditioner. A variety of electronic components are connected to the main controller 200, such that the main controller 200 can receive/transmit variety of data from/to the electronic components.

[94] In more detail, the main controller 200 includes a main memory 202. The main memory 202 is used as a storage medium basically mounted to the air-conditioner, such that it stores variety of data. For example, the main memory 202 stores sound data to be output from the sound output unit 222, etc.

[95] The main controller 200 is connected to a main input unit 210, a sensor unit 212, a signal receiver 214, a communication interface 215, an indoor-unit motor 216, an outdoor-unit motor 218, and a compressor 220, etc.

[96] The main input unit 210 allows a user to enter an operation signal of the air- conditioner via the button unit 130. The input signal received via the main input unit 210 is transmitted to the main controller 200.

[97] The sensor unit 212 includes a plurality of sensors mounted to the air-conditioner, for example, a temperature sensor, a moisture sensor, a dust sensor, and a gas sensor, etc. Accordingly, the sensor unit 212 measures an air state and an air-pollution level, such that the measurement values detected by the sensor unit 212 are transmitted to the main controller 200.

[98] The signal receiver 214 receives an external signal in the same manner as in the remote-controller receiver 140. A signal received in the signal receiver 214 is also transmitted to the main controller 200.

[99] The communication interface 215 may also be designed to receive/transmit wireless communication data (or signal) from/to a computer (or the Internet). In other words, the communication interface 215 can receive a variety of signals from an external part or can transmit state information of the air-conditioner to the external part.

[100] For example, the communication interface 215 can transmit/receive data to/from the

USB memory 160.

[101] The communication interface 215 can transmit/receive data using a variety of communication methods, for example, Infrared communication, Bluetooth communication, and Internet communication, etc.

[102] The Bluetooth communication is indicative of a communication method for wirelessly interconnecting a computer, household appliances, and a mobile terminal, which are located within a local area to implement two-way real-time communication.

[103] The indoor-unit motor 216 is contained in the indoor unit 100 of the air-conditioner, and rotates a fan. The indoor-unit motor 216 is operated by a signal received from the main controller 200. For example, if the main input unit 210 transmits an input signal of the operation/stop key 132 to the main controller 200, the main controller 200 operates the indoor-unit motor 216.

[104] The main controller 200 controls a rotation speed of the indoor-unit motor 216 on the basis of an air-pollution level received from the sensor unit 212.

[105] The compressor 220 and the outdoor-unit motor 218 are operated by the main controller 200. In more detail, if a user enters the operation/stop key 132 via the main input unit 210 in the same manner as in the indoor-unit motor 216, or if the user enters an operation command via the remote-controller receiver 140, the main controller 200 operates the compressor 220 and the outdoor-unit motor 218, etc., such that the air- conditioner is switched from the stop mode to the operation mode.

[106] The main controller 200 is also connected to additional devices (e.g., an air- cleaning unit 170 and a sound output unit 222, etc.).

[107] As previously stated above, the air-cleaning unit 150 filters impurities from the air to clean the air. The main controller 200 controls operations of the air-cleaning unit 170 upon receiving a signal from the main input unit 210. In more detail, as described above, the air-cleaning unit 170 is operated by an input signal of the plasma key 137 contained in the button unit 130.

[108] The main controller 200 automatically controls the degree of an air-cleaning operation (i.e., strength or weakness of the air-cleaning function) of the air-cleaning unit 170. In more detail, the main controller 200 detects an air-pollution level (e.g., dust or gas, etc.) measured by the sensor unit 212, and automatically adjusts the strength or weakness of the air-cleaning function of the air-cleaning unit 170 on the basis of the detected air-pollution level.

[109] A sound output unit 222 outputs sound or audio data, and is composed of a speaker, etc., such that it can output a variety of sounds (e.g., buzzer sound, melody sound, or music sound, etc.) For example, if an unexpected error occurs in any components of the air-conditioner, the sound output unit 222 outputs buzzer sound or various melody sounds based on individual avatar images or messages displayed on the display 256. In addition, if a music file is executed, the sound output unit 222 may output various music sounds.

[110] The main controller 200 communicates with the display controller 250 contained in the display unit 150. Air-conditioner operation signals such as an input signal of the operation/stop key 132 contained in the main input unit 210 are transmitted to the main controller 200, and are also be transmitted to the display controller 250, such that the display controller 250 forms a display screen image suitable for operating the air- conditioner.

[Ill] Data received in the display controller 250 via a data input unit 258 may also be transmitted to the main controller 200. A signal received via a display input unit 254 is transmitted to the main controller 200, such that it outputs sound via the sound output unit 222.

[112] The display unit 150 includes a display controller 250 for controlling content data to be displayed; a display 256 for being controlled by the display controller 250, and displaying an image or message; a display memory 252 for storing a variety of data to be displayed on the display 256; and an electronic album 253 for editing/storing a plurality of photo-images stored in the display memory 252.

[113] The display controller 250 for controlling displayed content data is connected to the display memory 252, the display input unit 254, the display 256, and the data input unit 258, etc.

[114] The display memory 252 is contained in the display unit 150, and stores various data (e.g., a photo-avatar or a character-avatar, etc.) for the display unit 150. In other words, the display memory 252 stores image data (e.g., avatar) to be displayed on the display 256.

[115] Needless to say, data displayed on the display 256 may also be stored in other memory (or recording medium), instead of the display memory 252. In other words, data stored in the main memory 202 or an electronic album 253 "s memory may also be stored in an external storage medium such as the USB memory 160.

[116] Data displayed on the display 256 is comprised of a still image or a moving-image file. In more detail, the data displayed on the display 256 is comprised of an avatar(character) or a photo file.

[117] The above-mentioned data can be stored while being classified according to folders, and is displayed in the form of various shapes. The display format of the above- mentioned data will hereinafter be described.

[118] A folder acting as a data storage space is formed by a user who desires to easily search for desired data in the memory of the computer. In more detail, the folder acts as a file cabinet for effectively managing a plurality of related files, and is the same as the directory for use in a DOS or UNIX system. The folder may include other folders and files as necessary.

[119] A plurality of photo-images are stored in the electronic album 253. The stored photo-images are displayed on the display 256.

[120] The electronic album 253 receives photo-images from an external part, stores the received photo-images, and outputs the stored photo-images on the display. In other words, the photo-images stored in the electronic album 253 can be transmitted/received to/from an external part via the communication interface 215 or the data input unit 258.

[121] The display unit 150 includes a variety of album functions 344 which transmit/ receive and edit the photo-images contained in the electronic album 253. A detailed description of the above-mentioned album function 344 will hereinafter be described.

The image file displayed on the image display 256'may be comprised of at least one of a JPEG file, a BMP file, and a TIFF file. The JPEG file, the BMP file, and the TIFF file have been widely used as extensions indicative of image data, and a detailed description thereof will herein be omitted for the convenience of description.

[126] The operation display 256"displays a variety of information (i.e., an operation state of the air-conditioner, a current temperature, or a setup temperature) in the form of a character (text) message or numerical message.

[127] The above-mentioned display 256 may be comprised of a Liquid Crystal Display

(LCD) or an organic EL (Electro-Luminescent), etc.

[128] The LCD is an electronic component for converting a variety of electrical information generated from a variety of devices into visual information using a variation in liquid crystal transmittance based on an input voltage.

[129] The organic EL is indicative of an organic material formed by a luminescence effect acquired when a current signal flows in a fluorescent organic compound. The organic EL is referred to as an Organic Light Emitting Diode (OLED) or an organic diode.

[130] The aforementioned LCD and the aforementioned EL have been recently researched by many developers, and have been widely used throughout the world, such that their detailed description will herein be omitted for the convenience of description.

[131] As stated above, the display controller 250 controls image-, character-, or numerical- data to be displayed on the display 256. An execution program of the display controller 250 may be implemented with a variety of languages.

[132] For example, the execution program is implemented with JAVA program language or C language (e.g., at least one of C, C++, or C# program languages).

[133] Preferably, the display controller 250 may implement a two-dimensional (2D) image on the display 256, or may implement a three-dimensional (3D) image on the display 256. In other words, a planar image or/and a stereoscopic image can be implemented on the display 256.

[134] The data input unit 258 receives data (or signals) from an external part via the USB memory 160 or the IEEE1394 port. The data input unit 258 allows the user to enter a photo or image to be displayed on the display window 120 or a music file (including an MP3 file) to be outputted via the sound output unit 222.

[135] FlG. 7 shows a variety of display modes displayed on a display window according to the present invention. In more detail, a variety of display modes displayed on the display window 120 by the display controller 250 are exemplarily shown in FlG. 7.

[136] Referring to FlG. 7, the display modes implemented by the display 256 include a standby mode 300 for indicating a standby state before an air-conditioning function is executed; an operation mode 320 for indicating current execution of the air- conditioning function; and a function selection mode 340 for allowing a user to select a variety of functions, etc.

[137] Generally, the standby mode 300 includes a screen-off mode 302 for displaying no image on a screen; a clock mode 304 for displaying a current time; a screen-saving mode 306 for executing a screen-saver program; and a user setup mode 308 for displaying an image established by a user. Accordingly, the standby mode 300 is designed to display at least one of the above-mentioned modes 302, 304, 306, and 308.

[138] In more detail, at least one of the screen-off mode 302, the clock mode 304, the screen-saving mode 306, and the user setup mode 308 has been generally set in the air- conditioner during a manufacturing process of the air-conditioner. However, if the user transmits a power-supply signal to the air-conditioner, the booting of the standby mode 300 is initially executed, such that the standby mode 300 is displayed on the display window 120.

[139] Needless to say, the setting information of the above-mentioned standby mode 300 may be changed to other information. In more detail, provided that the user may select a desired mode from among the screen-off mode 302, and the clock mode 304, the screen-saving mode 306, and the user setup mode 308, and the booting of the selected mode is executed, the selected mode may also be displayed on the display window 120 via the display 256.

[140] The screen-off mode 302 indicates that the display window 120 is powered off, such that the powered-off state of the display window 120 is maintained during the screen-off mode 302.

[141] The clock mode 304 indicates that a current time is displayed on the display window 120. Besides the current time information, the clock mode 304 further indicates month/year information, and at the same time may indicate a measurement value of the temperature sensor or the moisture sensor.

[142] The screen-saving mode 306 executes a predetermined screen-saving program. In more detail, the screen-saving mode 306 indicates that a screen saver is operated. Therefore, the screen-saving mode 306 displays a screen image acquired by the execution of the screen saver widely used for computers. [143] The user setup mode 308 displays an image pre-established by the user. In other words, the user freely pre-establishes a desired photo-image (i.e., a user's photo-image or a user's family photo-image) or his or her character image during the user setup mode 308, such that the air-conditioner displays the above pre-established image upon receiving a power-supply signal.

[144] The operation mode 320 shows state information of an image implemented by the display 256 when the air-conditioner is operated by the operation/stop key 132 at the standby mode 300. The operation mode 320 is classified into a real-operation mode 322, a user-operation mode 324, and a character operation mode 326, etc.

[145] Therefore, if the air-conditioner is operated, any one of the real-operation mode

322, the user-operation mode 324, and the character operation mode 326 contained in the operation mode 320 is executed. In other words, any one of the user-established modes is executed.

[146] The real-operation mode 322 displays an actual-object image (or a real photo) pre- stored in the main memory 202 or the display memory 252. The above-mentioned actual-object image may be comprised of a still image or moving images.

[147] The user operation mode 324 uploads a user-desired image or user-desired moving images to the display memory 252. Accordingly, the user selects the uploaded image or moving images, and the selected image or moving images are displayed on the display window 120.

[148] The character operation mode 326 displays a pre-stored character on the display window 120. The above-mentioned character may be configured in the form of a still image or a moving character. For example, if the character operation mode 326 is executed, a skiing character is displayed on the display window 120, and it is preferable for the skiing character to be displayed in the form of moving images.

[149] In the meantime, the above-mentioned operation mode 320 is continuously operated on the condition that an additional key signal for executing another command is not applied to the air-conditioner. If the air-conditioner stops operation in the operation mode 320, the operation mode 320 returns to the standby mode 300. In this case, the air-conditioner may perform an automatic cleaning function 310 when returning to the standby mode 300. However, it should be noted that the above-mentioned automatic- cleaning function 310 can be executed on the condition that it is pre-set in the air- conditioner.

[150] The above-mentioned operation mode 320 may also be switched to the screen- saving mode 306 according to a user command if the user enters no key until reaching a predetermined time after the operation mode 320 has been executed.

[151] If the user enters a predetermined key signal in the screen-saving mode 306, the screen-saving mode is automatically terminated, and returns to the operation mode 320.

[152] The function selection mode 340 allows the user to select/establish a variety of functions of the air-conditioner.

[153] The function selection mode 340 includes an operation/additional function 342 and an album function 344, etc.

[154] The operation/additional function 342 enables the user to establish an operation state and additional functions of the air-conditioner. The album function 344 allows the user to store/edit a variety of pictures.

[155] According to the operation function, the user selects state information (e.g., a cooling or dehumidifying function) of the air-conditioner, and can adjust the volume of wind of the air-conditioner.

[156] In the meantime, the pop-up function 360 may be further executed during the above-mentioned individual modes.

[157] The pop-up window 360 loads a variety of pop-up windows on the display window

120, such that the user can visually recognize an error state or input key state of the air- conditioner while the above-mentioned individual modes are executed.

[158] The above-mentioned function selection mode 340 may also be switched to the screen-saving mode 306 according to a user command in the same manner as in the operation mode 320. In other words, if the user enters no execution key until reaching a predetermined time after the function selection mode 340 has been executed, the function selection mode 340 is also switched to the screen-saving mode 306.

[159] FIGS. 8 to 14 shows screen images displayed when the album function 344 contained in the function selection mode 240 is selected.

[160] The album function 344 includes a variety of menus, for example, an "Album

View" menu for allowing a user to view stored photo-image(s), a "Photo Retrieve" menu for retrieving a desired photo-image from an external storage unit, a "Photo Rotate" menu for rotating the selected photo-image at a predetermined angle, a "Screen- Saver Setup" menu for setting the stored photo-image to a screen-saver image, a "Total Deletion" menu for deleting all the stored photo-images, and a "Selective Deletion" menu for selectively deleting some of the stored photo-images, etc.

[197] A method for executing individual modes having the above-mentioned configuration will hereinafter be described with reference to FIGS. 21 and 22.

[198] FIGS. 21 and 22 is a flow chart illustrating a display control method for an air- conditioner according to the present invention. In more detail, FIGS. 21 and 22 shows detailed operations of the standby mode 300, the operation mode 320, and the function selection mode 340.

[199] Referring to FIGS. 21 and 22, the display controller 250 determines whether a power-supply signal is received in the air-conditioner at step S400. If the power-supply signal is received in the air-conditioner, the air-conditioner executes the standby mode 300 at step S410. Otherwise, if the power-supply signal is not received in the air- conditioner, the air-conditioner executes no action.

[200] It is determined whether the operation/stop key 132 is pressed by the user at step

S420. If the user presses the operation/stop key 132 at step S420, a corresponding signal is transmitted to the main controller 200, such that the air-conditioner is operated at step S421. In other words, the main controller 200 operates air-conditioner components (e.g., an indoor-unit motor 216 or an outdoor-unit motor 218), resulting in the implementation of air-conditioning effect of room air at step S421.

[201] Otherwise, if the operation/stop key 132 is not pressed by the user at step S420, it is determined whether the plasma key 137 is pressed at step S430. If the plasma key 137 is pressed by the user at step S430, a corresponding signal is transmitted to the main controller 200, and operates the air-cleaning unit 170, resulting in the implementation of an air-cleaning function at step S432.

[202] It is determined whether the stop key is pressed at step S434 while the air-cleaning function is executed by the air-cleaning unit 170. If the stop key is pressed, a corresponding signal is transmitted to the main controller 200, such that the air-cleaning unit 170 stops operation at step S436. In this case, the stop key indicates the plasma key 137 pressed by the user. In other words, if the user presses the plasma key 137 once, the air-cleaning unit 170 starts operation. Under this condition, if the plasma key 137 is re-pressed by the user, the air-cleaning unit 170 stops operation.

[203] If the air-conditioning function is executed at step 421, the operation mode 320 is executed on the display window 120 at step 440.

[204] If the operation mode is executed at step S440, the display memory 252 sets a time

(T) to zero as denoted by "T=O" at step 460. It is determined whether a specific function key (e.g., the left key 138 or the right key 139) is pressed via the button unit 130.

[205] If the function key is pressed at step S462, the function selection mode 340 is executed at step S480. Otherwise, if the function key is not pressed at step S462, it is determined whether the operation/stop key 132 is pressed at step S464.

[206] If the operation/stop key 132 is not pressed, the air-conditioner reads the time value stored in the display memory 252 at step S466, such that it determines whether the stored time value T is equal to or higher than the time setup value (e.g., 5 minutes) established by the environment setup process at step S468.

[207] If the time value T is equal to or higher than the time setup value at step S468, the air-conditioner executes the screen-saving mode 306 at step S470. If a specific key is pressed, the screen-saving mode 306 is closed at step S474.

[208] If the function selection mode is executed at step S480, the display memory 252 reestablishes a time. In more detail, the time is set to zero as denoted by "T=O" at step S530. It is determined whether the right key 139 acting as a function close key is pressed via the button unit 130 at step S532.

[209] If the right key 139 acting as the function close key is pressed at step S532, the current mode returns to the operation mode. Otherwise, if the right key 139 is not pressed at step S532, it is determined whether the operation/stop key 132 is pressed at step S534.

[210] If the operation/stop key 132 is not pressed, the air-conditioner reads the time value stored in the display memory 252 at step S536, such that it determines whether the stored time value T is equal to or higher than the time setup value (e.g., 5 minutes) established by the environment setup process at step S538.

[211] If the time value T is equal to or higher than the time setup value at step S538, the air-conditioner executes the screen-saving mode 306 at step S540. If a specific key is pressed, the screen-saving mode 306 is closed at step S544.

[212] It is determined whether the operation/stop key 132 is pressed at steps S464 and

S534. If the operation/stop key 132 is pressed, the main controller 200 stops operation of the air-conditioner, such that the air-conditioning function stops operation at step S550.

[213] If the air-conditioner stops operation, an automatic cleaning function is executed at step S552. Needless to say, the automatic cleaning function can be executed when it is pre-established in the air-conditioner by the user.

[214] Thereafter, it is determined whether a power-off state is established at step S560. If the power-off state is established at step S560, all operations of the display are closed at step S570. Otherwise, if the power-off state is not established at step S560, the current mode returns to the standby mode.

[215] For example, although the present invention has disclosed the electronic album 253 installed separately from the display memory 252, it should be noted that the electronic album 253 may also be installed in the display memory 252 if required. In other words, the display memory 252 may perform not only unique functions but also the electronic album function for storing the photo-image at the same time if required. Industrial Applicability

[216] As apparent from the above description, the air-conditioner according to the present invention performs an electronic album function to edit/store images, and displays the stored data in the form of various shapes.

[217] Therefore, the air-conditioner can store/edit photo-images, can classify variety of data according to categories, can manage the above-mentioned data, can search for a desired photo-image in the stored photo-images, such that the user can conveniently operate the air-conditioner simultaneously employing additional functions thereof, resulting in greater convenience of the user.

[218] 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 inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
