Definitions

  • the present invention relates to a refrigerator with a self-illuminating function display.
  • Refrigerators of this type are known in which a seven-segment display is used as the function display for the digital representation of numbers from large-format LEDs in one Control panel is arranged above the door of the device. Traditionally this is Function display switched on continuously as long as the refrigerator is in operation. Thereby electrical energy is consumed unnecessarily.
  • the object of the invention is to provide a refrigerator with a light function display, at the unnecessary energy consumption is avoided by the indicator light, and at which is less likely to fail.
  • an operating panel 2 is arranged above the door 1, on the various controls and buttons 3 for setting the functioning of the Refrigeration device are arranged.
  • an infrared-transmissive window 4 behind an infrared sensor for detecting those moving in the vicinity of the refrigerator People is arranged.
  • a light function display on the control panel 2, e.g. a two-digit seven-segment display made of LEDs or a backlit LCD display to show the temperature inside the refrigerator or another operating variable that can be selected by the user by entering the 3 keys of the refrigerator.
  • a detection signal output of the sensor 5 is with a trigger input a timing circuit 6 connected to trigger the timing circuit 6 when a changing level of the detection signal the detection of a person in the vicinity of the Displays the refrigerator.
  • the timing circuit 6 can be designed as a simple monostable multivibrator each time it is triggered for a predetermined period of time e.g. some Minutes a switching device connected to its output, such as a transistor 7 permeable switches. So can an operating current through the transistor 7 and the seven-segment display 8 flow, which makes their LEDs light up. After the expiration of the predetermined switch-on time of the time circuit 6, this switches the transistor 7 again impermeable, and the indicator light 8 goes out.
  • the time circuit 6 can also be made more monostable by connecting two in series Flip-flops can be formed, the first of which is caused by a change in the level of the Output signal of the sensor 5 is activated and for a period of e.g. about 10 Sec. Provides a non-vanishing output signal. The falling edge of this output signal triggers the second flip-flop, whose output signal in turn triggers the transistor 7 permeable switches. This way there will be some delay between the Detecting a person by the sensor 5 and switching on the light indicator 8 reached, with the result that the person has in the meantime had time to use the refrigerator to approach. This ensures that the indicator light is not already on is before the person sees the device.
  • a switch 9 which can be actuated by one of the keys 3 is connected in parallel to the transistor 7.
  • the switch 9 is shown in FIG. 2 in the open position; by closing the switch 9 can the seven-segment display 8 permanently and regardless of the detection result of the sensor 5 can be supplied with power if a user so wishes.
