Definitions

  • the heater (7) is also operated during almost the entire time period that the compressor (4) operates.
  • the temperature of the freezing compartment (3) is lowered, thus preventing thawing/melting of the foodstuffs inside the freezing compartment (3), but also the foodstuffs inside the fresh food compartment (2) are prevented from freezing. Consequently, both compartments (2, 3) are provided to operate effectively without utilizing any electronic system. Ease of production and cost advantage are maintained by controlling the cooling device (1) with the thermostatic switch (8) and the bimetal switch (9).
  • a mechanically controlled cooling device (1) wherein the compartments (2, 3), kept at different temperatures, are cooled effectively even at low ambient temperature conditions.
  • the total cost of the product is decreased by means of the bimetal switch (9) and the thermostatic switch (8) used for the control of the cooling device (1) having a much lower cost than the electronic control systems.
  • the heater (7) is activated only at low ambient temperature conditions and thereby unnecessary energy consumption is prevented.

Claims (5)

  1. Kühlvorrichtung (1), umfassend ein Kühlfach (2), in das Lebensmittel zum Kühlen gelegt werden, ein Gefrierfach (3), das auf niedrigeren Temperaturen als das Kühlfach (2) gehalten wird und in das Lebensmittel zum Einfrieren gelegt werden, einen Kompressor (4), der Kältemittelfluid im Kühlzyklus verdichtet und zirkulieren lässt, einen Kühlfachverdampfer (5), der dafür sorgt, dass das Innere des Kühlfachs (2) gekühlt wird, einen Gefrierfachverdampfer (6), der dafür sorgt, dass das Innere des Gefrierfachs (3) gekühlt wird, wenigstens eine Heizeinrichtung (7), die an und/oder in der Nähe des Kühlfachverdampfers (5) angeordnet ist, und einen Thermostatschalter (8), der an und/oder in der Nähe des Kühlfachverdampfers (5) angeordnet ist und den Betrieb des Kompressors (4) abhängig von dem dadurch erkannten Temperaturwert steuert, gekennzeichnet durch einen Bimetallschalter (9), der an und/oder in der Nähe des Gefrierfachverdampfers (6) angeordnet ist, in Reihe mit der Heizeinrichtung (7) verbunden ist und den Betrieb der Heizeinrichtung (7) abhängig von dem dadurch erkannten Temperaturwert steuert.
  2. Kühlvorrichtung (1) nach Anspruch 1, dadurch gekennzeichnet, dass der Thermostatschalter (8) den Kompressor (4) aktiviert, wenn die erkannte Temperatur (TR) die Aktivierungstemperatur (TRcut-in) des Kompressors (4) erreicht, die vom Hersteller vorgegeben ist, während der Kompressor (4) deaktiviert ist, und den Kompressor (4) deaktiviert, wenn die erkannte Temperatur (TR) die Deaktivierungstemperatur (TRcut-out) des Kompressors (4) erreicht, die vom Hersteller vorgegeben ist, während der Kompressor (4) aktiviert ist.
  3. Kühlvorrichtung (1) nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass der Bimetallschalter (9) dafür sorgt, dass die Heizeinrichtung (7) betrieben wird, indem der Kreislauf verlängert und vollständig ausgeführt wird, wenn die Temperatur (TF) eine obere Grenztemperatur (TFmax) erreicht, die vom Hersteller vorgegeben ist, während die Heizeinrichtung (7) nicht aktiviert ist, und dafür sorgt, dass die Heizeinrichtung (7) deaktiviert wird, indem der Kreislauf verkürzt und ausgeschaltet wird, wenn die Temperatur (TF) eine untere Grenztemperatur (TFmin) erreicht, die vom Hersteller vorgegeben ist, während die Heizeinrichtung (7) aktiviert ist.
  4. Kühlvorrichtung (1) nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass die Heizeinrichtung (7) in der Nähe des Thermostatschalters (8) angeordnet ist.
  5. Kühlvorrichtung (1) nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass der Thermostatschalter (8) einen Befehlsabschnitt (10), worin der Schaltvorgang durchgeführt wird, und einen Sensorabschnitt (11) umfasst, der mittels eines Drahts mit dem Befehlsabschnitt (10) verbunden ist und die Erkennung der Temperatur ermöglicht.
