  • The display unit 30 is mounted in and separated from the door 20. The display unit 30 displays an image, and performs various functions such as TV, Internet, and home shopping functions. The display unit 30 includes a display 40 for displaying an image, a power supply unit 50 for selectively supplying power to the display 40, a temperature detector 60 for detecting temperature of the display 40, and a controller 70 for controlling the power supply unit 50 based on the temperature detected by the temperature detector 60.
  • The display 40 comprises a case unit 41 forming an outer shape thereof and formed with an exposed opening, an image display part 43 which is exposed to the outside through the exposed opening of the case unit 41 to display an image, a sound unit 45 for outputting sound, and electric elements (not shown) (e.g., a main board) for generating and transmitting a signal to the image display part 43 and the sound unit 45. Here, a flat display panel, such as a liquid crystal display (LCD) or a plasma display panel (PDP), or other known in the art is used for the image display part 43, and a speaker is used for the sound unit 45. In addition, a control button 47 for controlling the display unit 30 (e.g., turning on/off the display unit 30 and selecting channels) is provided at one area of the case unit 41. Here, in addition to the control button, the display unit 30 comprises a remote controller (not shown) for wirelessly controlling the display unit 30.
  • The power supply unit 50 selectively supplies and interrupts the power to/from the display 40. The power supply unit 50 is accommodated in the case unit 41 of the display 40.
  • The temperature detector 60 detects the temperature of the display 40. The temperature detector 60 is mounted on the electric element (e.g., the main board) which generates heat to detect the temperature. However, the temperature detector 60 is mounted on the case unit 41 to detect the temperature. The temperature detector 60 detects the temperature of the display 40 and transmits the result to the controller 70.
  • The controller 70 controls the power supply unit 50 to interrupt the power from the display 40 when the temperature detected by the temperature detector 60 is greater than a predetermined maximum temperature. Here, the maximum temperature is established by controlling the display unit 30 according to user's preference. According to an embodiment of the present invention, the maximum temperature is established to be approximately 60° C., at which a user can feel the heat intensely. Accordingly, the display 40 is prevented from being overheated.
  • In addition, the controller 70 shows a warning message before interrupting the power supplied to the display unit 30. In further detail, when the temperature detected by the temperature detector 60 reaches the predetermined maximum temperature, the warning message is displayed on the image display part 43. Here, the warning message is flickered on the image display part 43, or displayed on the image display part 43 in a large size font. In addition, the controller 70 is output a warning message sound through the sound unit 45. The warning message sound is periodically output, or it may be continuously output.
  • When the temperature detected by the temperature detector 60 reaches the predetermined maximum temperature and the power to the display 40 is interrupted, the controller 70 controls the power supply unit 50 to maintain interrupting the power from the display 40 until the temperature detected by the temperature detector 60 reaches a predetermined reference temperature. Here, the reference temperature is established to be a temperature at which the user does not feel the heat intensely and the display 40 is stably driven. In addition, the reference temperature is variously established and changed according to the user's preference. Accordingly, while the display 40 is overheated, since the power is not supplied to the display 40 even when the user operates the control button 47 to apply the power to the display 40, the display 40 is prevented from being overheated.
  • Further, when the power is forcibly applied to the display 40 by the user when the temperature detected by the temperature detector 60 reaches the predetermined maximum temperature and the power supplied to the display 40 is interrupted, the controller 70 controls the power supply unit 50 to supply the power to the display 40. In this case, when the temperature detected by the temperature detector 60 reaches the predetermined maximum temperature after supplying the power to the display 40, the warning message is output from at least one of the image display part 43 and the sound unit 45 to control the power supply unit 50 to interrupt the power supplied to the display 40.
  • A controlling method of the refrigerator according to an embodiment of the present invention will now be described with reference to FIG. 3.
  • As shown in FIG. 3, when the display unit 30 is driven by the control button 47, the controller 70 controls the power supply unit 50 to supply the power to the display 40 at operation 1.
  • In addition, from operation 1, the process moves to operation 3, where while the display 40 is driven, the controller 70 compares the temperature detected by the temperature detector 60 to the predetermined maximum temperature.
  • Here, in operation 3, when it is determined that the temperature detected by the temperature detector 60 is greater than the predetermined maximum temperature, the process moves to operation 5, where the controller 70 outputs the warning message through at least one of the image display part 43 and the sound unit 45.
  • In addition, the process moves to operation 7, where the controller 70 controls the power supply unit 50 to interrupt the power supplied to the display 40. According to an embodiment of the present invention, the controller 70 controls the power supply unit 50 to interrupt the power supplied to the display 40 after elapsing a predetermined time from a time when the warning message is displayed.
  • According to an embodiment of the present invention, when the display 40 is driven by the control button 47 while the power supplied to the display 40 is interrupted at operation 7, the controller 70 controls the power supply unit 50 to keep interrupting the power from the display 40 until the temperature detected by the temperature detector 60 reaches the predetermined reference temperature.
  • In addition, when the display 40 is driven by the control button 47 while the power supplied to the display 40 is interrupted at operation 7, the controller 70 controls the power supply unit 50 to supply the power to the display 40, to output the warning message in a like manner as in operation 5, when the temperature detected by the temperature detector 60 reaches the predetermined maximum temperature, and controls the power supply unit 50 to interrupt power supplied to the display portion 40.
