Definitions

  • the invention relates to a cooling device with a compressor and at least two in series connection arranged evaporators having a different cooling capacity for cooling cold compartments of different temperatures, of which in the compartment higher temperature, a lighting device and a temperature sensor are arranged which is at least approximately the same as the temperature of the compartment, generates a signal supplied to a control device, the lighting device serves as a heating device.
  • Such a cooling device is known from EP-A-0161967.
  • refrigerators with a normal refrigerator compartment and a *** or **** freezer compartment which are equipped with a single-circuit refrigerator, the refrigerant compressor in the majority of cases by one arranged in the refrigerator compartment so-called constant-on controller is controlled. This is done with the help of this controller the compressor when a set on the controller and on the refrigerator compartment evaporator is reached switched off by means of a temperature sensor and after An upper temperature limit ensuring defrosting of the refrigerator compartment evaporator is reached put back into operation. With such a temperature control the temperature in the freezer depends both on the temperature set in the controller Desired temperature in the refrigerator compartment as well as the heat in this compartment.
  • the invention is based, for cooling devices according to the preamble of the task Claim 1 to provide a heater with which the disadvantages of The prior art are avoided and with which the Temperature control of the mentioned cooling devices with different heat incidence is improved.
  • the lighting device a series resistor designed as a capacitor can be connected in series by which the power output of the lighting device is reduced.
  • the temperature control is also possible Single-circuit refrigerators operated cooling units with *** or **** freezer compartments lower ambient temperatures of the devices significantly improving heating device provided, their range of use by simply adjusting the series resistor serving condenser with different heat incidence in the refrigerator compartment charged refrigerators and freezers is expanded.
  • a Capacitor as a series resistor for that operated as a heating device Lighting device ensures that in addition to the heating device no Raising the cooling compartment temperature contributing heating source is present because of the capacitive series resistor no heat output drops.
  • the Use of a capacitive series resistor use conventional, conventional ones Incandescent lamps for heating purposes in the event that for temperature control at certain Device types only require a very low heating output, for example approx. 5 watts is. Due to the possibility of heating power more commercially available, usually for Lighting device used in refrigerators and freezers Increase incandescent lamps for the respective application as heating significantly can, the energy balance is operated with such a heating device Refrigerator and freezer significantly improved.
  • the capacitor can be switched by a switch in a circuit, in which precedes the lighting device with the capacitor as a series resistor is.
  • a switch is particularly easy to use and easy to train, if after a next preferred embodiment of the subject of the invention provided is that the switch is designed as a manually operated switch.
  • a particularly useful training for a capacitor results if according to a next preferred embodiment of the subject of the invention it is provided that the capacitor has a capacitance of 100 nF to 1 ⁇ F, however preferably has a capacitance of 680 nF.
  • the temperature sensor the temperature of the evaporator detected in the higher temperature compartment.
  • the temperature in the compartment of higher temperature is recorded particularly precisely if after an alternative embodiment of the object of the invention is provided that the temperature sensor the temperature of the refrigerator compartment air in the compartment at higher temperature detected.
  • a household table refrigerator 10 is shown, on its heat-insulating Housing 11 a door 12 is hinged.
  • the heat insulating case 11 is used to hold a *** freezer compartment 13, which has a vertical Axis pivotable freezer compartment door 14 is closable.
  • a normal cooling compartment 15 is provided below the freezer 13, separated from it in a heat-insulating manner, which equipped with several shelves 17 held on its side walls 16 is.
  • the normal refrigerator compartment 15 and the freezer compartment 13 are each one not shown Evaporator cooled, which are connected in series in the refrigerant circuit arranged and acted upon by a single refrigerant compressor with refrigerant are.
  • the temperature in the normal refrigerator compartment 15 and in the freezer compartment 13 is a the door stop side wall 16 of the normal refrigerator 15 arranged control device adjustable, which is designed as a so-called constant-on controller and Is part of a controller-lamp combination 18. This is for this purpose one not shown, tapping the temperature of the refrigerator compartment evaporator Temperature sensors and one located in the area near the door for adjustment the temperature serving knob 19.
  • the area away from the door of the controller-light combination 18 comprises a section serving as lighting device 20, which is equipped with an incandescent lamp, not shown.
  • the lighting device 20 is in a circuit 21, which of a 230 lying on the input poles 22 of the circuit 21st V AC voltage is fed.
  • a first switch 23 is arranged, which is part of the regulator-lamp combination and which is operated by the door 12, the switch 23 when closed Door 12 is in its open position I while it is open Door 12 is in its closed position II and thus the power supply to Lighting device 20 allows.
  • a capacitor 24 is arranged in series with the lighting device 20, which as a series resistor for operating the lighting device 20 as Serves heating device and which via a second switch 25 in the circuit 21st is switchable.
  • the switch 25 can be used both as a manually operated switch be formed, which then by an operator of the table refrigerator 10 in its closed position II is brought when the ambient temperature of the Table refrigerator drops below a preset value and thus the natural one Incidence of heat in the normal cooling compartment 15 is significantly reduced.
  • the closed position II of the switch 25 the light bulb of the lighting device closed door 12 operated as a heater and over the as a series resistor serving capacitor 24 is energized, thereby the power output and thus their Heating effect is reduced by the voltage drop across the capacitor 24.
  • the switch can also be used as electronic switch, e.g. Thyristor or triac, which has a corresponding control circuit is controlled.
  • Thyristor or triac which has a corresponding control circuit is controlled.
  • This is, for example, as an input signal the signal of the ambient temperature of the table refrigerator 10 Detecting temperature sensor supplied so that the trained as a triac or thyristor Switch when the ambient temperature drops below one certain default value is closed and thus the bulb of the Lighting device 20 is operated as a heating device.
