  • a temperature sensor 29 Installed on an outer surface of or in the inside of the carbonator 11 is a temperature sensor 29 which detects whether the temperature of the carbonator 11 is equal to or less than a predetermined temperature and then transmits a signal to a controller 55.
  • the recessed portion 20 has a size slightly greater than that of the carbonator 11 so that the carbonator 11 can be housed therein. Between the carbonator 11 and inner surface of the recessed portion 20, a plurality of protrusion members 21 made of an insulating material are disposed in such a manner that the carbonator 11 is fixedly installed in the recessed portion 20 with five sides of the carbonator 11 spaced apart from the inner surface of the recessed portion 20 while forming gaps therebetween as deep as the height of the protrusion members 21.
  • a cover 30 is provided to overlay the recessed portion 20 and the carbonator 11 mounted therein.
  • the cover 30 is fixed to the inner surface of the freezer door 10 by screws (not shown) or the like.
  • a plurality of the protrusion members 21 are disposed to form a gap as deep as the height of the protrusion members 21 between the inner surface of the cover 30 and the back side of the carbonator 11.
  • an inlet channel 25 and an outlet channel 24 are formed, respectively.
  • the inlet channel 25 and the outlet channel 24 are intended for establishing communication between the recessed portion 20 and the freezer compartment 60.
  • solenoid valves 26a and 26b controlled by the controller 55 are installed at the inlet channel 25 and the outlet channel 24, respectively.
  • an outlet opening 125 of an outlet path (not shown) and an inlet opening 124 of an inlet path (not shown) are formed, respectively, both paths being intended for establishing communication between the recessed portion 20 and the outside of the refrigerator.
  • the inlet path serves to introduce warm air outside the refrigerator into the recessed portion 20, whereas the outlet path serves to discharge the air in the recessed portion 20 to the outside of the refrigerator.
  • solenoid valves 126a and 126b controlled by the controller 55 are installed, respectively.
  • a fan device 31 is installed at the outlet channel 24 to forcedly discharge the air in the recessed portion 20 to the inside of the refrigerator, i.e., the freezer compartment 60.
  • a separate fan device may be installed at the inlet channel 25 without or in addition to the fan device 31 to forcedly blow the cool air in the freezer chamber 60 into the recessed portion 20.
  • the controller 55 controls the solenoid valves 26a, 26b, 126a and 126b in response to the signal from the temperature sensor 29. If the controller 55 receives the signal from the temperature sensor 29, the controller 55 controls the solenoid valves 26a and 26b to block the inlet channel 25 and the outlet channel 24, and controls the fan device 31 to stop its operation. Then, the supply of the cool air of the freezer compartment 60 to the recessed portion 20 is shut off so that the temperature of the carbonator 11 does not lowered.
  • the controller 55 controls the solenoid valves 126a and 126b to open the outlet opening 125 and the inlet opening 124, so that the warm air outside the refrigerator is introduced into the recessed portion 20 through the inlet path and the inlet opening 124 to flow into the gaps formed between the carbonator 11 and the inner surfaces of the recessed portion 20 and the cover 30 to raise the temperature of the carbonator 11. And, the air in the recessed portion 20 is discharged to the outside of the refrigerator through the outlet opening 125 and the outlet path.
  • the controller 55 controls the solenoid valves 126b and 126a to block the inlet opening 124 and the outlet opening 125, respectively, and controls the solenoid valves 26a and 26b to open the inlet channel 25 and the outlet channel 24. So, the warm air is not supplied to the recessed portion 20 from the outside of the refrigerator and the cool air in the freezer compartment 60 is supplied to the recessed portion 20 and then flows through the gaps formed between the carbonator 11 and the inner surfaces of the recessed portion 20 and the cover 30 to cool down the carbonator 11. At this time, the controller 55 controls the fan device 31 to start its operation so that the supply of the cool air from the freezer compartment 60 to the recessed portion 20 is facilitated.
  • Fig. 4 is a partial cross-sectional diagram of a modified embodiment of the preferred embodiment shown in Fig. 3, wherein like parts to those of the preferred embodiment of the present invention are represented by like reference numerals, and detailed descriptions thereof will be omitted for simplicity.
  • a cover 30a for overlaying the recessed portion 20 and the carbonator 11 mounted therein is provided, which is fixed to the inner surface of the freezer door 10 by screws (not shown) or the like.
  • a plurality of the protrusion members 21 are disposed to form gaps therebetween as deep as the height of the protrusion members 21.
  • the cover 30a has an empty inner space 37 formed therein. Further, as shown in Fig. 5, the cover 30a has an inlet through hole 32 and an outlet through hole 33 formed in an upper and lower portion of a base plate of the cover 30a, respectively.
  • the inner space 37 communicates the recessed portion 20 through the inlet through hole 32 and the outlet through hole 33.
  • the relatively warmer air in the recessed portion 20 flows into the inner space 37 through the inlet through hole 32 and then is cooled in the inner space 37 indirectly by the cool air of the freezer compartment 60.
  • the air cooled in the inner space 37 descends to the lower portion of the inner space 37 and then flows into the recessed portion 20 through the outlet through hole.
  • the carbonator 11 is then cooled down by help of the air circulation between the recessed portion 20 and the inner space 37 of the cover 30a.
  • outlet opening 125 of the outlet path (not shown) and the inlet opening 124 of the inlet path (not shown) are formed at the upper and the lower portion of the recessed portion 20, respectively. As similar as in the preferred embodiment, both paths are intended for establishing communication between the recessed portion 20 and the outside of the refrigerator. And, at the outlet opening 125 and the inlet opening 124, solenoid valves 126a and 126b controlled by the controller 55a are installed, respectively.
  • the controller 55a controls the solenoid valves 126a and 126b in response to the signal from the temperature sensor 29. If the controller 55a receives the signal indicating that the temperature of the carbonator 11 is equal to or less than a predetermined temperature from the temperature sensor 29, the controller 55a controls the solenoid valves 126a and 126b to open the outlet opening 125 and the inlet opening 124. Then, the warm air outside the refrigerator is introduced into the recessed portion 20 through the inlet path and the inlet opening 124. In addition, the air in the recessed portion 20 is discharged to the outside of the refrigerator through the outlet opening 125 and the outlet path. Thus, the temperature of the carbonator 11 mounted in the recessed portion 20 is raised by the warm air flowing through the gaps formed between the carbonator 11 and the inner surfaces of the recessed portion 20 and the cover 30a.
  • the controller 55a controls the solenoid valves 126a and 126b to block the outlet opening 125 and the inlet opening 124, so that the carbonator 11 is cooled down by the air circulation between the recessed portion 20 and the inner space 37.
  • the temperature control apparatus for use in a carbonator of a refrigerator in accordance with the present invention has a construction in which the temperature of the carbonator mounted in the recessed portion of the freezer door is controlled by the cool air inside the refrigerator and the warm air outside the refrigerator.
