Definitions

  • the invention relates to a cooling device according to the preamble of the first claim.
  • a manually operable Mains switch provided by means of electromechanical Contacts performs the required switching operation.
  • the power switch can be triggered by a button Locking device assigned that removed from the power switch is arranged by its actuator. Of the The mains switch is locked in the on position, this locking only by pressing the additional key can be specifically unlocked and then automatically switches to the off position.
  • the invention is based, with one Cooling device according to the preamble of the first claim Take measures by which with simple means an unintentional turning off of the power switch can be prevented.
  • a cooling device is the power switch with only one Provide switch-off delay device so that in the event of inadvertent or inadmissible actuation of the In any case, the mains switch still has time in the switched-on position remains to restore the switch-on state. It is it expedient at the end of the selectable or predetermined Time delay value this process acoustically and / or optically to signal to the initiated To draw attention to the switch-off process. It can corresponding signal also beyond the switch-off time at least visually maintained to spoil it to counteract any goods that may still be stored. For the sake of safety, the appropriate facility for Switch-off time delay constructed so that the process of Time delay only expires as long as a trip element is operated manually.
  • the one assigned to the power switch Device for the switch-off time delay preferably has an electronically controllable timer on the by means of an electrically connected to its control input connected switch must be started. After this This automatic reset button must start until the delay period expires in actuated Position held when an actual Switching off a corresponding supply circuit for the cooling device is to be reached. Otherwise, one only brief actuation of the push button ignored.
  • the device preferably has one electronic counter based on a predetermined Delay time value is preset and during the Actuation of the push button used for counter control counts down from a preset value or up to increments a preset value and then the Switching off causes.
  • a corresponding to the count Display value can be on an optical display device, in particular an LCD display. It is for example, it is possible to count down from one preset value, for example 5, during the Expiry of the time delay to another value, for example to count the value 0. After completing this Counting the device or an electrical operated device part switched off.
  • the Control of the expiry of the time delay time preferably made by a microprocessor which the corresponding display elements depending on the Pressing the push button controls. It is expedient, the status of the device or the concerned device part to be switched off in a memory store, especially in an EEPROM, which too Customer service purposes can be queried.
  • the display of the Time delay value can also alternate with a temperature display in the same display and by means of the same display elements are made.
  • the Device for delayed switch-off can be a Contain element that is in the manner of a monostable flip-flop or an R-C controlled Schmitt trigger is. It is advisable to press the key switch at the same time for restarting the supply circuit use, switching on without time delay he follows.
  • this structure one becomes one electrical supply circuit switched on, in particular electronically trained or electronic controlled power switch after a manually triggered Start of a time delay device with a time delay switched on in the switched-off state, when the start condition of the time delay device beyond the preset time delay value is maintained.
  • the activation of the power switch in contrast, the switch-off state is instantaneous.
  • the unintentional switch-on should only be done under Additional conditions may also be possible Switch-on process analogous to the switch-off process with appropriate facilities can be controlled.
  • the invention is based on a schematic diagram additionally explained.
  • a cooling device not shown in the drawing, in particular a freezer 1, has an operating and Display panel 2 on the front below one Worktop 3 and above a front door 4 is arranged.
  • the aperture integrated display element 7 in particular controlled by a microprocessor appears in the normal operating case is the one currently prevailing in the cold room Temperature.
  • the display switched so that one of the preset switch-off delay corresponding Value is displayed, for example from a Display value 5 during the actuation period of the Key switch 5 to another value, example value the value 0 is counted down. Only when this value is reached, the power supply is switched off especially for driving the refrigerant circuit.
  • an aperture 2 can also be assigned Warning element 8 at least during the course of Time delay must be activated and an acoustic and / or give an optical warning signal. If this Warning signal even during the switch-off phase of the Supply network can be maintained by means of a Acknowledgment button 9 to switch off this warning signal be made when the turn-off process actually has been consciously controlled.
  • This warning signal can also then be activated if the cooling is insufficient Cold store the prescribed low storage temperature cannot be maintained.
  • the power switch by means of the push button 5 can by actuating the same again, preferably using it the microprocessor the renewed, especially instantaneous The mains switch is switched on. Otherwise, the Alarm device 8 is not activated as long as the normal Operating condition of the cooling device exists and the Key switch 5 is not actuated.
