Definitions

  • Refrigerators of the type mentioned with a normal refrigerator compartment and a three-star or.
  • Four-star freezer compartments are equipped with a single-circuit refrigeration machine, the refrigerant compressor of which is controlled either by a so-called constant-on controller located in the refrigerator compartment, or by an electronic control device.
  • the compressor is switched off when a temperature set on the control device and sensed on the refrigerator compartment evaporator by means of a temperature sensor is reached, and is restarted after an upper temperature limit ensuring defrosting of the refrigerator compartment evaporator is reached.
  • the temperature prevailing in the freezer compartment depends both on the set temperature in the refrigerator compartment set on the control device and on the heat input into this compartment.
  • a control circuit which, although to a large extent guarantees the operation of the lighting device as a heater, the cost of the circuit for controlling the lighting device is inexpensive, with the capacitor used in this control circuit being expensive beats.
  • the invention is based on the object of proposing a control circuit for operating the lighting device as a heating device in a cooling device according to the preamble of claim 1, in which the circuit structure is simplified and the circuit complexity is reduced with the aid of simple measures.
  • the means are equipped with a particularly favorable efficiency if, according to a preferred embodiment of the object of the invention, it is provided that the means are designed as a thyristor. To generate control signals with different polarity, two thyristors must be provided in anti-parallel connection.
  • the control circuit for operating the lighting device as a heating device can be constructed in a particularly simple manner if, according to an alternative embodiment of the object of the invention, it is provided that the means are designed as a triac.
  • control signals are formed by positive and / or negative half-waves of an AC voltage signal.
  • control signals for the lighting device serving as the heating device are provided in a cost-effective manner.
  • the activation of the lighting device is particularly favorable if, according to the last preferred embodiment of the subject of the invention, it is provided that the evaluation unit evaluates the closed or open state of the door of the cooling device via at least one sensor and, depending on the state de?
  • the means in the closed state are acted upon with a predetermined number of control signals of the same and / or different polarity, or the means in the open state with an at least approximately the open time corresponding control signals of the same and / or different polarity.
  • Fig. 2 shows the lighting device in a suitable for its operation as a refrigerator lighting and as a heating device
  • Fig. 3 shows the time course of control signals used to control the lighting device as a heating device.
  • a household table refrigerator 10 is shown with a door 11 shown in the open state, which serves to close an access opening in a heat-insulating housing 12 for receiving refrigerated goods.
  • the heat-insulating housing 12 is equipped with a three-star freezer compartment 13, which can be closed with a freezer compartment door 14 which can be pivoted about a vertical axis.
  • a normal cooling compartment 15 is provided below the freezer compartment 13 in a heat-insulating manner and is equipped with a plurality of shelves 17 held on its side walls 16.
  • the normal refrigerator compartment 15 and the freezer compartment T3 are each cooled by an evaporator, not shown.
  • the evaporators are arranged in series in the refrigerant circuit and acted on by a single refrigerant compressor with refrigerant.
  • an electronic evaluation unit 19 arranged in a controller housing 18, symbolically represented in FIG. 2, to which an illumination device 20, which in the present exemplary embodiment is designed as an incandescent lamp, is also arranged in the controller housing 18.
  • the lighting device 20 is located in a circuit 21, which is fed by a 230 V AC voltage present at the input poles 22 of the circuit 21.
  • a door switch 23 that can be actuated by the door 11 is provided, which is closed when the door 11 is open (position II), as a result of which the lighting device 19 is connected to the electric circuit 21.
  • a triac 24 serving as control means is provided in the present exemplary embodiment, the gate connection of which is controlled by an electronic evaluation unit 25, which controls the triac 24 via its gate connection as a function of the compartment temperature prevailing in the normal cooling compartment 15 and detected by a temperature sensor (not shown) .
  • the triac 24 actuates the lighting device 20 in a clocked manner, positive half-waves 27 of the AC voltage serving as voltage supply for the circuit 21 being used in the present exemplary embodiment, as shown in FIG. 3.
  • the positive half-waves 27 correspond to the required one Heating power spaced apart at a time interval t.
  • a combination of positive and negative half-waves has proven to be particularly favorable.
