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. Un dispositif de refroidissement (1) comprenant un compartiment d'aliments frais (2) où les aliments à refroidir sont placés, un compartiment de congélation (3) où les aliments à congeler sont placés, maintenu à des températures plus basses que le compartiment d'aliments frais (2), un compresseur (4) qui comprime et circule le fluide frigorigène dans le cycle de refroidissement, un évaporateur du compartiment d'aliments frais (5) qui permet le refroidissement de l'intérieur du compartiment d'aliments frais (2), un évaporateur du compartiment de congélation (6) qui permet le refroidissement de l'intérieur du compartiment de congélation (3), au moins un dispositif de chauffage (7) qui est disposé sur et/ou dans le voisinage de l'évaporateur du compartiment d'aliments frais (5), et un interrupteur thermique (8) qui est disposé sur et/ou dans le voisinage de l'évaporateur du compartiment d'aliments frais (5) et qui commande l'opération du compresseur (4) en fonction de la valeur de température détectée, caractérisé par un interrupteur bimétallique (9) qui est disposé sur et/ou dans le voisinage de l'évaporateur du compartiment de congélation (6), qui est relié au dispositif de chauffage (7) en série et qui commande l'opération du dispositif de chauffage (7) en fonction de la valeur de température détectée.
  2. Un dispositif de refroidissement (1) selon la Revendication 1, caractérisé par l'interrupteur thermostatique (8) qui active le compresseur (4) lorsque la température détectée (TR) atteint la température d'activation (TRcut-in) du compresseur (4) prédéterminée par le fabricant lorsque le compresseur (4) est désactivé et désactive le compresseur (4) lorsque la température détectée (TR) atteint la température de désactivation (TRcut-out) du compresseur (4) prédéterminée par le fabricant lorsque le compresseur (4) est activé.
  3. Un dispositif de refroidissement (1) selon la Revendication 1 ou 2, caractérisé par l'interrupteur bimétallique (9) qui permet le fonctionnement du dispositif de chauffage (7) en allongeant et complétant le circuit lorsque la température (TF) atteint une température limite supérieure (TFmax) prédéterminée par le fabricant lorsque le dispositif de chauffage (7) n'est pas activé et permet la désactivation du dispositif de chauffage (7) en raccourcissant et éteignant le circuit lorsque la température (TF) atteint une température limite inférieure (TFmin) prédéterminée par le fabricant lorsque le dispositif de chauffage (7) est activé.
  4. Un dispositif de refroidissement (1) selon l'une quelconque des revendications précédentes, caractérisé par le dispositif de chauffage (7) qui est disposé dans le voisinage de l'interrupteur thermostatique (8).
  5. Un dispositif de refroidissement (1) selon l'une quelconque des revendications précédentes, caractérisé par l'interrupteur thermostatique (8) comprenant une partie de commande (10) où l'opération de commutation est effectuée et une partie de capteur (11) qui est reliée à la partie de commande (10) par l'intermédiaire d'un fil et qui permet la détection de la température.
