[54] The front panel 20 is connected to the cabinet 10 and the hinge 21 in the same manner as a door, such that it is opened while being rotated forward.
[55] The input unit 40 is located at a lower part of the display unit 30, and is composed of a plurality buttons.
[56] As can be seen from FlG. 2 or 3, the display unit 30 includes a display window 32 mounted to the front panel 20 to provide a user with information, and a drive 35 for displaying not only operation states of the air-conditioner but also images such as avatars.
[57] The display window 32 is a flat panel display such as a Liquid Crystal Display

[58] The drive 35 includes general structural components for displaying data on the display window 32 according to a signal of a controller of the air-conditioner.
[59] In this case, the display unit 30 includes a memory for storing data and a slot 70 connected to an external device to receive external data. The slot 70 is mounted to the drive 35 located at a back surface of the front panel 20.
[60] The slot 70 includes a Universal Serial Bus (USB) port 72 and a memory slot 130.
The USB port 72 is connected to a USB memory or a USB device. The memory slot 130 includes a memory 75, such that the memory 75 is inserted into the memory slot 130.
[61] The IEEE1394 port may substitute for the USB port 72 if required. Provided that the display window 32 is mounted to the front panel 20, the USB port 72 may also be mounted to the front panel 20.
[62] The air-conditioner includes a plurality of memory slots 130 according to memory card types. For example, the memory card 120 corresponds to an XD (xD picture card), a SD (SecureDigital card), an SMC (SmartMedia card), a memory stick, a multimedia card, a memorystick-pro, a memorystick-duo, a memorystick-produo, a CFl, a CF2, or a micro-drive, etc.

The display 140 has LEDs connected to the drive 35, such that a user can recognize necessary information via the LEDs. [64] In the meantime, the cabinet 10 includes a filter 61 for filtering the air received from the suction opening 13 or 14.
[65] FlG. 4 is a front view illustrating an input unit of a display unit of an indoor unit according to the present invention.
[66] Referring to FlG. 4, the input unit 40 includes a plurality of buttons for receiving signals or commands from the user.
[67] An operation/stop button 42 (also called an ON/OFF button) for operating/stopping the air-conditioner is located at the center of the input unit 40.
[68] Temperature buttons 43 and 44 for adjusting a set temperature are located above or below the operation/stop button 42. The upper temperature button 43 acts as a button for increasing the set temperature, and the lower temperature button 44 acts as a button for reducing the set temperature.
[69] Volume buttons 45 and 46 are located at right and left sides of the operation/stop button 42, and adjust the volume of sound of a speaker (not shown) mounted to the indoor unit. The left volume button 45 acts as a button for reducing the volume of sound of the speaker, and the right volume button 46 acts as a button for increasing the volume of sound of the speaker.
[70] A wind-volume button 47 for adjusting the volume of wind is located at a left lower side of the input unit 40. A plasma button 48 for operating an air-cleaning device is located at a right lower side of the input unit 40.
[71] The temperature buttons 43 and 44 and the volume buttons 45 and 46 are used to move a cursor on the condition that a specific menu is selected in a function selection mode.
[72] A control system for use in the air-conditioner includes a memory card, reads type information of the memory card, and outputs data of the memory card, and a detailed description of the control system will hereinafter be described.
[73] FlG. 5 is a block diagram illustrating an air-conditioner according to the present invention.
[74] Referring to FlG. 5, the air-conditioner according to the present invention includes a memory mounting unit 53, a memory 55, an output unit 54, and a controller 56. The memory mounting unit 53 enables the memory card to be inserted therein, and creates a signal for indicating the insertion of the memory card. The memory 55 stores data for discriminating types of the inserted memory card. The output unit 54 outputs not only type information of the memory card inserted into the memory mounting unit 53 but also processed data. If the signal indicating the insertion of the memory card has been created via the memory mounting unit 53, the controller 56 reads type information of the memory card and card data, and outputs the read information to the output unit 54.
[75] The memory mounting unit 53 includes a plurality of memory card slots to which at least one memory card can be inserted. If the memory card has been inserted into the memory mounting unit 53, the memory mounting unit 53 creates the signal indicating the inserted memory card, and outputs the created signal.
[76] For example, the memory mounting unit 53 includes a memory card slot to which a variety of memory cards (e.g., XD, SD, MMC, memorystick, and CF, etc.) having different- sizes and pin numbers can be inserted. If any one of the above-mentioned memory cards (XD, SD, MMC, memorystick, and CF, etc.) is inserted into the memory mounting unit 53, the memory mounting unit 53 creates a signal indicating the inserted memory card, and outputs the signal.
[77] The memory 55 stores memory data for discriminating card types when the signal indicating the inserted memory card is transmitted to the controller 56 after having been created from the memory mounting unit 53.
[78] For example, the memory 55 stores data (e.g., the number of pins of the memory card to discriminate memory-card type information, and the size of each pin, etc.) of various memory cards (XD, SD, MMD, memorystick, and CF, etc.).
[79] The controller 56 includes a card-type reader 51 and a data processor 52. The card- type reader 51 reads type information of a card mounted to the memory mounting unit 53. The data processor 52 processes data stored in the card, such that it outputs data stored in the read memory card to the output unit 54.
[80] Upon receiving the signal indicating the inserted memory card from the memory mounting unit 53, the card-type reader 51 compares the read signal with memory card data stored in the memory 55, and discriminates memory-card type information according to the result of the comparison.
[81] In this case, the memory card data includes a variety of information, for example, the number of memory-card pins, the size of pins, and a controllers port voltage resulting from insertion of a memory card.
[82] The data processor 52 reads data of the memory card read by the card-type reader
51, and controls the read data to be outputted to the speaker or display contained in the output unit 54.
[83] For example, if the data stored in the memory card is a music file (e.g., MP3, MP4, or ASX, etc.), the data processor 52 outputs sound data to the speaker contained in the output unit 54, and displays the words of music or song on the display contained in the output unit 54. If the data stored in the memory card is a picture file or a moving-image file, the data processor 52 outputs data stored in the memory card to the output unit 54.
[84] In this case, in the case where content data stored in the memory card is outputted via the output unit 54, the data processor 52 displays type information of the memory card read by the memory-card type reader 51 on the display of the output unit 54.
[85] Needless to say, an additional display for displaying type information of the memory card may also be contained in the air-conditioner. [86] As stated above, the above-mentioned air-conditioner includes the memory card, reads type information of the memory card, and processes/outputs data of the memory card, and a detailed description of the air-conditioner will hereinafter be described. [87] FlG. 6 is a block diagram illustrating a detailed configuration of a control system of an air-conditioner according to the present invention. [88] Referring to FlG. 6, the indoor unit for use in the air-conditioner includes a c ontroller 80 for controlling overall operations of the air-conditioner. The controller 80 is connected to a variety of electronic components, and enables variety of data to communicate with the electronic components. [89] In this case, the controller 80 receives data from a sensor unit 85 for detecting indoor/outdoor temperatures, pipe pressure/temperature, and indoor humidity/dust, etc.
The controller 80 receives an operation command of the user from the receiver 50 which receives signals from the remote-controller 100 or the input unit 40. [90] The controller 80 receives data from the sensor unit 85 and operation conditions of the air-conditioner, such that it controls a compressor 62, an indoor-unit motor 63 of an indoor ventilator, an outdoor-unit motor 64 of an outdoor ventilator, a speaker 65, and an air-cleaning unit 66. [91] The controller 80 connected to the slot 70 receives data via the slot 70. The controller 80 includes a USB interface 88 and a memory card interface 89. The USB interface 88 controls the USB memory 110 connected to the USB port 72 of the slot
70. The memory card interface 89 controls the memory card 120 connected to the memory slot 130. [92] The USB interface 88 interacts with the USB memory 110 inserted into the USB port 72, such that it is connected to a circuit via the USB memory 110. The memory card interface 89 interacts with the memory card 120 inserted into the memory slot
130, such that it is connected to a circuit via the memory card 120. [93] In this case, the USB memory 110 or the memory card 120 stores variety of data, such that the data is displayed on the display window 32 according to a command of the controller 80. [94] The controller 80 determines which one of memory cards 120 has been inserted into the memory slot 130, and switches on LEDs of the display 140, such that the user can recognize the determined memory card via the LEDs. [95] As stated above, the display 140 can display type information of the memory card, operation states of the air-conditioner, and data of the memory card using the LEDs, and a detailed description thereof will hereinafter be described. [96] FIG. 7 shows a display state of memory card data of an air-conditioner according to the present invention. [97] Referring to FlG. 7, the controller 80 displays the memory-card type, the memory- card data, and the operation state of the air-conditioner on the display unit 30.
[98] As can be seen from FlG. 7(a), if the memory card is inserted into the memory card slot, type and data of the inserted memory card are displayed on the display unit 30. In this case, if content data stored in the memory card is composed of a variety of files, the stored content data configured in the form of a list is displayed on the display screen. The user selects a desired item from among the list displayed on the display screen by pressing a variety of function buttons (not shown) contained in the air- conditioner, such that the user can operate individual files stored in the memory card.
[99] As can be seen from FIGS. 7(b) to 7(c), if the user selects a music file from among the list by pressing a variety of function buttons contained in the air-conditioner, an operation state of the air-conditioner is displayed on the display screen, and at the same time sound data corresponding to the operation state is outputted to the speaker of the air-conditioner. If the user selects a picture file from among the list of files stored in the memory card, the selected picture file is displayed on the display screen, such that the user can immediately recognize content data stored in the memory card.
[100] A method for discriminating a memory card of the air-conditioner will hereinafter be described.
[101] FlG. 8 is a flow chart illustrating a method for discriminating a memory card, and outputting data stored in the memory card according to the present invention.
[102] Referring to FlG. 8, according to the method for discriminating the memory card and outputting data stored in the memory card, a user firstly inserts a memory card 120 into any one of memory slots 130 at step S801.
[103] A current signal is applied to the memory slot 130, such that it is determined whether the memory card 120 has been correctly inserted into the memory slot 130. The controller 80 communicates with the memory card 120, such that it determines type information of the inserted memory card 120 at step S802.
[104] The controller 80 processes the data stored in the memory card at step S 803, displays type information of the memory card on the display, and outputs the data stored in the memory card at step S804.
[105] In this case, the above step S802 checks the flow of a current signal generated from the controller 80 to the memory card 120 via the memory slot 130, such that it can determine if the memory card 120 is correctly inserted into the memory slot 130. If the controller 80 determines that the memory card 120 is incorrectly inserted into the memory slot 130 or does not recognize the memory card 120, it displays specific information indicating the above-mentioned situation on the display 140.
[106] If content data stored in the memory card 120 is a music file or a moving-image file, video data of the content data is displayed on the display of the air-conditioner, and at the same time audio data there of is outputted via the speaker via the air- conditioner.
[107] A method for discriminating the inserted memory card and a method for processing/outputting data of the memory card will hereinafter be described with reference to HGS. 9-10.
[108] FlG. 9 is a circuit diagram illustrating a controller and a memory card for use in an air-conditioner according to the present invention. FlG. 10 is a block diagram illustrating a method for discriminating a memory card of an air-conditioner according to the present invention.
[109] A representative example of the memory card 120 is a multimedia card (hereinafter referred to as an MMC card), such that the MMC card will be used as an example for the convenience of description and better understanding of the present invention.
[110] The memory card interface 89 of the controller 80 is connected to the memory slot
130, such that it forms a circuit. The controller 80 includes a plurality of ports communicating with the MMC card 122. The memory card interface 89 applies a current signal to any one of ports communicating with the MMC card 122 at any time, checks the presence or absence of a response to the current signal, such that it can determine whether the memory card 120 is inserted or not.
[Ill] If the MMC card 122 is inserted into the memory slot 130, the controller 80 applies a reset command 122a composed of 0 and 1 to a command port of the MM Card 122. The MMC card 122 answers the reset command 122a, and transmits the response signal 122b to the controller 80, such that the controller 80 can determine whether the MMC card 122 is correctly inserted by referring to the response signal 122b.
[112] In this case, the memory card 120 inserted into each memory slot 130 can individually determine whether the memory card 120 is inserted according to the above- mentioned method. The memory card 120 determines the presence or absence of the response signal received from each slot of the memory slot 130, and determines whether one or more memory cards have been inserted into the memory slot 130.
[113] FlG. 11 is a block diagram illustrating another method for discriminating a memory card for use in an air-conditioner according to the present invention.
[114] Referring to FlG. 11, the controller 80 includes a ground (GND) 81, a command port 82, and first and second ports 83 and 84. The MMC card 122 of the memory card includes ports corresponding to individual ports of the controller 80.
[115] If the memory cards 122 and 124 are inserted, the GND 81 connects an electrode to the memory cards 122 and 124, such that it interconnects the memory cards 122 and 124. As can be seen from FlG. 1 l(a), the first and second ports 83 and 84 are in a pull- up state during which a predetermined voltage is maintained when the memory cards 122 and 124 have not been inserted. [116] In this case, if the user inserts the memory card (MMC, SD) into the memory slot
130, the GND 81 is connected to the first and second ports 83 and 84, such that voltages of the ports 83 and 84 are reduced, and the controller 80 recognizes the reduced voltages of the ports 83 and 84. Therefore, the controller 80 can determine whether the memory cards 122 and 124 have been inserted into the memory slot 130, and can also determine which one of memory cards 120 has been inserted into the memory slot 130.
[117] For another example, as can be seen from FIG. 1 l(b), a plurality of memory cards
122 and 124 are inserted into the memory slot 130, and the controller 80 applies a reset command 82a via a command port 82.
[118] The memory card 130 inserted into the memory slot 130 transmits response signals
82b and 82c of the reset command 82a to individual ports 83 and 84, respectively. The controller 80 detects the response signals 82b and 82c from the individual ports 83 and 94, such that it recognizes type information of the memory card 130.
[119] In this case, provided that the ports 83 and 84 are connected to the GND 81, the voltages of the ports 83 and 84 are reduced below a predetermined voltage, and the response signals 82b and 82c are not received in the ports 83 and 84, the controller 80 switches on LEDs of a specific message which commands a user to re-insert the corresponding memory card, which has not transmitted the response signals 82b and 82c, into the memory slot 130.
[120] It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
