Definitions

  • This invention relates to a cooling device and a control method thereof, wherein quick-freeze process is performed more effectively.
  • Cooling devices comprise a freshfood compartment to preserve foods and beverages and a freezing compartment for frozen foods.
  • the aim of the present invention is the realization of a cooling device and a control method thereof wherein the heater inside the freshfood compartment is controlled in order to prevent the freshfood compartment from being heated in an uncontrolled manner and to decrease the electric consumption cost of the user during the quick- freeze process.
  • the cooling device and the control method thereof designed to fulfill the objectives of the present invention are illustrated in the attached figures where: [007] Fig.l - is a schematic view of a cooling device.
  • Fig.2 - is a flowchart of a control method of a cooling device.
  • Fig.3 - is a circuit diagram illustrating the connection structure of a thermostat, a compressor and a heater. [010] Parts shown in figures are numbered as follows: 1. Cooling device 2. Freshfood compartment 3. Freezing compartment 4. Compressor 5. Freshfood compartment evaporator 6. Freezing compartment evaporator 7. Heater 8. Thermostat 9. Adjusting button 10. Quick-freeze switch 11. Heater switch 12. Compressor switch
  • the cooling device (1) comprises a freshfood compartment (2) wherein foods and beverages are preserved, a freezing compartment (3) used to preserve the foods frozen, a compressor (4) whereby the refrigeration cycle is accomplished, a freshfood compartment evaporator (5) ensuring that the internal volume of the freshfood compartment (2) is cooled by absorbing thermal energy, a freezing compartment evaporator (6) that is in series with the freshfood compartment evaporator (5), a heater (7) inside the freshfood compartment (2), an adjusting switch (9) enabling the user to chose the quick-freeze state or the operation state that changes between the maximum and minimum values, corresponding to different amounts of refrigeration, and ac cordingly determining the activation and/or deactivation temperatures of the compressor (4) and, a thermostat (8) sensing the temperature of the freshfood compartment (2) so that the compressor (4) is turned on and off with respect to the position of the adjusting button (9), if the adjusting button (9) is set to the quick-freeze state, activating the heater (7) at a temperature lower than the deactivation
  • the compressor (4) is turned on.
  • the heater (7) is not activated since the freshfood compartment (2) cannot reach low temperatures immediately when the compressor (4) is first turned on. After the temperature of the freshfood compartment (2) drops a few degrees, the thermostat (8) activates the heater (7).
  • the heater (7) is kept activated until the quick-freeze process is completed or the temperature of the freshfood compartment (2) increases up to a limiting value which is set in order to prevent overheating.
  • TI is the temperature at which the thermostat (8) deactivates the compressor (4), when the adjusting button (9) is at maximum state,
  • T2 is the temperature at which the thermostat (8) deactivates the compressor (4), when the adjusting button (9) is at quick-freeze state,
  • T3 is the temperature at which the thermostat (8) activates the heater (7)
  • T4 is the temperature at which the thermostat (8) deactivates the heater (7)
  • T5 is the temperature at which the thermostat (8) activates the compressor (4).
  • the thermostat (8) is connected in series with the power supply on one side and the compressor (4) and heater (7) on the other side. Electrically, the compressor (4) and the heater (7) are connected in parallel.
  • the thermostat (8) comprises a heater switch (11) connected in series with the heater (7), made of temperature-sensitive material, which closes the circuit when the temperature of the freshfood compartment (2) reaches the activation temperature (T3) of the heater (7) and opens the circuit when the temperature of the freshfood compartment (2) reaches the deactivation temperature (T4) of the heater (7), a compressor switch (12) connected in series with the compressor (4), made of temperature-sensitive material, which closes the circuit when the temperature of the freshfood compartment (2) reaches the activation temperature (T5) of the compressor (4) and opens the circuit when the temperature of the freshfood compartment (2) reaches the deactivation temperature (TI or T2) of the compressor (4), and a quick-freeze switch (10) positioned serially before the heater switch (11), which closes the circuit if the adjusting button (9) is set to the quick-
  • the thermostat (8) activates the compressor (4) and the heater (7) with respect to the states set by the adjusting button (9) considering the temperatures (TI T2, T3, T4, T5).
  • the relation between the temperatures is T2 ⁇ T3 ⁇ TI ⁇ T4 ⁇ T5. Since the temperature (T3) where the thermostat (8) activates the heater (7) is lower than the deactivation temperature (TI) of the compressor (4) when the adjusting button is set to the maximum state, the heater is never activated during the normal operation state.
  • the quick-freeze process is carried out as follows:
  • step (105) wherein the temperature of the freshfood compartment (2) is sensed and compared with the temperature (T3) at which the thermostat (8) activates the heater (7), [025] - If the compressor (4) is not operating, sense the temperature of the freshfood compartment (2) and compare it with the temperature (T5) at which the thermostat (8) activates the compressor (4) (103), [026] - If the temperature of the freshfood compartment (2) is lower than the temperature (T5) at which the thermostat (8) activates the compressor (4), go back to step (102) wherein it is checked whether the compressor (4) is operating, [027] - If the temperature of the freshfood compartment (2) is higher than the temperature (T5) at which the thermostat (8) activates the compressor (4), turn on the compressor (4) (104), [028] - Sense the temperature of the freshfood compartment (2) and compare it with the temperature (T3) at which the thermostat (8) activates the heater (7) (105), [029] - If the temperature of the freshfood compartment (2) is checked, [027] - If the temperature of
  • the thermostat (8) senses the te mperature on the freshfood compartment evaporator (5).
  • the thermostat (8) controls the on / off operations of the compressor (4) and the heater (7) with respect to the temperature values that it senses on the freshfood compartment evaporator (5).
