Definitions

  • the present invention is concerned with a temperature control mechanism used in controlling temperature in preferably two compartment refrigerators.
  • refrigerators with fresh food compartment and a freezer compartment various methods of control are used to secure that such freezer and fresh food compartments remain at desired temperature ranges.
  • desired temperature is provided by distributing cool air between various compartments
  • working periods of the compressor are adjusted in accordance with temperature sensed through thermostatic control device in fresh food compartment or freezer compartment and shutters, mechanic shutter, lids, gates and similar mechanisms are used to adjust air flow by reducing or widening the passage opening between the compartments.
  • adjustment of air passage opening between compartments is carried out by means of thermostatic control at distinct points.
  • the object of the present invention is to provide a single temperature control mechanism both to provide a thermostat control to adjust the temperature of the freezer and fresh food compartment and to control the air flow between those compartments and also to provide a precise adjustment as well.
  • Refrigerator (1) comprise a fresh food compartment (2) to preserve food, a freezer compartment (3) to store food by freezing, a temperature control mechanism (4) to adjust the temperature of the freezer (3) and fresh food (2) compartments.
  • the temperature control mechanism (4) comprises a thermostat (5) which adjusts the temperature of the fresh food compartment (1), an air passage opening (6) to ensure air passage between the freezer (3) and fresh food (2) compartments, a shutter valve (8) to adjust the air passage opening (6) according to the desired air flow, a thermostat holder (7) that accomodates the thermostat (5) and the said shutter valve (8), an adjustment button (9) for the rotation of the shutter valve (8) at the same time with regulating thermostat (5), a shaft bed (13) located at the centre of the adjustment button (9), a shutter valve shaft (12) to transmit the motion taken from the shaft bed (13) to the shutter, a thermostat shaft (11) to transmit the motion generated by the shutter shaft (12) to the thermostat (5).
  • the circular motion generated by the adjustment button (9) is transmitted without using any auxiliary transmission means to the shaft bed (13) placed on the same axis from the said shaft bed (13) to shutter valve shaft (12) and from this latter to thermostat shaft (11).
  • the shutter valve (8) is in the form of a helical cam to adjust the air passage opening (6) to a desired size.
  • the shutter valve (8) comprises a slit (10) which ensures a limited amount of air from the freezer compartment (3) to the fresh food compartment (2) when the refrigerator needs to consume less power for instance in the vacation mode.
  • shutter valve (8) While the shutter valve (8) is turned via the adjustment button (9) to adjust to the highest allowable temperature degree of the fresh food compartment (2) in vacation mode, the thermostat (5) is adjusted to the minimum position to allow minimum cooling. In this position shutter valve (8) completely closes the air passage opening (6), by means of the slit (10) minimum amount of air passes through the fresh food compartment (2) from the freezer compartment (3). ( Figure 3 ).
  • the shutter valve (8) is rotated via adjustment button (9) to allow maximum air flow from the freezer compartment (3) to the fresh food compartment (2) which makes the air passage opening (6) fully opened, while at the same time the thermostat (5) is adjusted to a value that enables the cooling close to maximum ( Figure 5 ).
  • the temperature control mechanism (4) comprises a motion transmission element (14) to locate the thermostat (5) and the shutter valve (8) at distinct places inside the refrigerator (1) to control the performance of the thermostat (5) and the shutter valve (8) from a single point and to transmit the motion created by the adjustment button (9) to shutter valve (8) by connecting the shaft bed (13) which transmits the motion direct to the thermostat shaft (11) in the same time to the shutter valve shaft (12) ( Figure 8 ).
  • Adjustment of the thermostat (5) and air flow from the freezer compartment (3) to the fresh food compartment (2) from a single point provides easiness and low cost wise manufacturing process.
  • the special form of the shutter valve (8) allows a precise adjustment of the air flow.
  • the temperature control mechanism (4) provides the refrigerator to operate efficiently in vacation mode or in fast freezing positions.

Claims (5)

  1. Kühlschrank (1), umfassend ein Fach für frische Lebensmittel (2), ein Tiefkühlfach (3) und einen Temperatursteuermechanismus (4), wobei der Temperatursteuermechanismus (4) ein Thermostat (5) umfasst, das die Einstellung der Temperatur im Fach für frische Lebensmittel (2) erlaubt, eine Luftdurchlassöffnung (6), die einen Luftdurchlass zwischen dem Tiefkühlfach (3) und dem Fach für frische Lebensmittel (2) ermöglicht, ein Absperrorgan (8), das die Luftdurchlassöffnung (6) entsprechend einer gewünschten Luftströmung einstellt, eine Thermostathalterung (7) zum Unterbringen des Thermostats (5) und des Absperrorgans (8), einen Einstellknopf (9) zum Drehen des Absperrorgans (8) zusammen mit dem Thermostat (5), ein Wellenlager (13) in der Mitte des Einstellknopfes (9), eine Absperrorganwelle (12) zum Übertragen der Bewegung vom Wellenlager (13) auf das Absperrorgan (8), und eine Thermostatwelle (11) zum Übertragen der Bewegung, die von der Absperrschieberwelle (12) erzeugt wird, auf das Thermostat (5), und wobei der Temperatursteuermechanismus (4) dadurch gekennzeichnet, dass das Absperrorgan (8) die Form eines schraubenförmigen Nockens aufweist, um die Luftdurchlassöffnung (6) auf eine gewünschte Größe einzustellen, wobei er eine Kreisbewegung um einen Mittelpunkt herum vollzieht.
  2. Kühlschrank (1) nach Anspruch 1, dadurch gekennzeichnet, dass die Kreisbewegung, die von dem Einstellknopf (9) erzeugt wird, auf das Wellenlager (13) auf derselben Achse wie vom Wellenlager (13) zur Absperrorganwelle (12) übertragen wird, und von dieser auf die Thermostatwelle (11), ohne dass zusätzliche Übertragungsmittel verwendet werden.
