I
  • One common cooling and air flow arrangement for a sideby-side refrigerator-freezer has a single refrigerant evaporator located behind a vertical panel forming the liner rear wall of the freezer compartment. That panel forms the front wall of a vertical passageway containing the evaporator and a main fan for drawing air from the freezer compartment into the lower end of the passageway. The air is chilled and moisture removed as it passes through the evaporator. Most of the air is directed into the upper end of the freezer compartment for recirculation therein, while a small part is directed through or around the common insulating wall between the freezer and refrigerator compartment to the upper portion of the refrigerator compartment. A return air passage is also provided through or around the insulating wall between the refrigerator and freezer compartments. A damper, either manually or thermostatically controlled, is typically provided for the inlet passage.
  • My invention is intended to provide a fast chill space in the refrigerator compartment in the vicinity of the inlet passage through which chilled air is delivered to the refrigerator space.
  • an auxiliary fan which is energized independently of the main fan for the main cooling system is provided.
  • the fan is timer controlled so that in energizing the fan a selected time period of fan operation is also established.
  • Housing means for the fan is provided so that the extent of communication of the suction side of the fan with the space in the refrigerator compartment relative to the inlet passage for chilled air from the freezer space can be established.
  • the relationship of the communication between the refrigerator space and the inlet passage from the freezer side favors that of the refrigerator space to a substantial degree to limit the temperature of the air discharged by the auxiliary fan to a value of about freezing when the cooling system of the freezer side is operating. Accordingly, during operation of the auxiliary fan when the cooling system of the freezer side is not operating the temperature of the air discharged by the auxiliary fan will be substantially that of the temperature of the air as a whole in the refrigerator space.
  • FIG. 1 is a perspective view of a side-by-side refrigeratorfreezer embodying my invention with the door for the refrigerator compartment omitted and an auxiliary door at the front of the fast chill space in its closed position;
  • FIG. 2 is a fragmentary perspective view of the upper portion of the refrigerator compartment with the auxiliary door raised and in retracted position underlying the top wall of the refrigerator compartment;
  • FIG. 3 is a front elevational view of a diagrammatic character for illustrating one example of the general relationship of the main parts of the system according to my invention
  • FIG. 4 is a horizontal section, also of diagrammatic character, corresponding to one taken along the line IV-IV of FIG. 3;
  • FIG. 5 is a simplified schematic of one example of an electrical circuit for energizing the auxiliary fan.
  • the side-by-side refrigerator-freezer shown in FIG. 1 includes a freezer side space 2 and a refrigerator side space 4 in a common cabinet.
  • the fast chill space 6 is located at the upper end of the refrigerator compartment 8.
  • An auxiliary door 10 comprising a perimetric frame and a translucent panel is adapted to be moved to its position in FIG. 1 to close the front of the fast chill space 6 when the fast chill operation is to be carried out.
  • the door is retractable to a position in which it underlies the top wall of the refrigerator compartment (as shown in FIG. 2) when the fast chilling operation is not being carried out and the upper part of the compartment is to simply be used for general purpose storage.
  • an auxiliary fan housing 12 is provided in the upper, left rear comer of the refrigerator compartment 8.
  • the housing may also be used to mount the temperature control and adjusting knob 14 for the compartment.
  • a timer panel 16 is shown mounted on the left wall of the fast chill space and carries a timer switch knob 18. The timer panel may also conveniently carry a list of different food items which typically may require chilling, and the particular time periods suggested for accomplishing the chilling of each particular food article.
  • An ordinary open-work refrigerator shelf 20 is provided at the generally lower boundary of the fast chill space to support articles to be fast chilled, and to support general articles when a fast chill operation is not being carried out.
  • FIGS. 3 and 4 the general arrangement of parts in a side-by-side refrigerator-freezer of one type with which the invention may be utilized, and the general air flow system, will now be described.
  • a vertically disposed panel 22 forming the rear liner wall of the freezer compartment 24 is spaced forwardly from the insulated rear wall 26 of the cabinet sufficiently to accommodate the thickness of a refrigerant evaporator 28 and the main fan means 30, and to form a vertically extending passage 32 at the rear of the freezer compartment.
  • the air flow through this passage is in an upward direction with the air being admitted to the open lower end 34 from the lower portion of the freezer space.
  • Openings 36 at the upper end of the panel 22 permit most of the air forced up the passage to be discharged into the freezer compartment 24.
  • a minor portion of the air flowing at the upper end of the passage is directed through the inlet passage 38 extending through the common insulated wall 40, separating the freezer compartment 24 from the refrigerator compartment 8, to the interior of the auxiliary fan housing 12.
  • a damper 42 is provided for the inlet passage 38 to control the amount of air admitted to the refrigerator compartment 8 through the inlet passage.
  • the damper may be arranged to be manually adjusted it is indicated in FIG. 4 as being thermostatically controlled, as is also conventional, by the provision of a temperature responsive means 44.
  • the means 44 senses the temperature in the refrigerator compartment and moves the damper toward open and closed positions in accordance with the differential between the temperature at which the means 44 is set and the refrigerator compartment air temperature.
  • the knob 14 (FIG. 2) is used to set the thermostatic control means 44 to maintain the refrigerator compartment at a warmer or cooler temperature.
  • the return of air from the lower part of the refrigerator compartment 8 to the lower part of the freezer compartment 24 is through the passage 46 in the lower portion of the common wall 40.
  • the auxiliary fan 48 driven by motor 50 is located in the auxiliary fan housing 12.
  • the arrangement may be a simple propeller type fan in a fan ring arrangement 52 which also defines the opening through which air is discharged when the fan is operating.
  • Inclined louvers 54 at the discharge opening direct the air partly downwardly.
  • a number of openings 56 are provided in the bottom face of the auxiliary fan housing 12 to place the interior of the fan housing in relatively open communication with the space in the refrigerator compartment 8.
  • the communication with the refrigerator space is substantially less restricted than the communication with the inlet passage 38.
  • the communicating relationships may conveniently be arrived at empirically, and are such that when the auxiliary fan 48 is operated in the absence of a cooling operation occurring in the freezer side, the temperature of the air circulated by the auxiliary fan is only slightly depressed from the existing refrigerator compartment temperature. For example, if the refrigerator space is at about 38 F. in the upper portion thereof, the auxiliary fan will typically draw only sufficient air through the restricted communication with the inlet passage 38 (which in turn is in communication with the freezer passage 32) to depress the temperature a degree or two at most.
  • the air being discharged by the auxiliary fan 48 may be at, say, 32 F. with a F. compartment setting and a refrigerator compartment setting of about 38 F.
  • the auxiliary fan 48 will be operating part of the time while a cooling operation is occurring in the freezer side, and part of the time in the absence of a cooling operation.
  • the compressor will perhaps run two or three times per hour with, say, a 40 percent run time at a 70 F. room temperature and, say, a 60 percent run time at a 90 F. room temperature. lf a load is introduced into the freezer side when the fast chill operation is to occur, the compressor may run continuously for an hour to bring the temperature in the freezer side down and to cool the articles which created the load.
  • a heavy load may be introduced into the refrigerator compartment by the articles themselves, and this will tend to raise the air temperature of the compartment as a whole, including the temperature of the air being circulated in the fast chill.
  • the chilling will still be faster than if the air were not being circulated.
  • the added heat due to the fast chill operation will raise the temperature of air returning to the freezer side and thereby prolong the cooling operation.
  • FIG. 5 A schematic for the electrical circuit for operating the fast chill arrangement, including optional controls therein, is shown in FIG. 5.
  • the switch [8 indicates a manually set, mechanical timer switch for energizing the fan motor 50.
  • a door switch 58 which is closed when the main door for the refrigerator compartment is closed, is also ordinarily advisable.
  • An optional switch 60 controlled by thermostatically responsive means 62 in the fast chill space, may be provided to serve as a low temperature limit switch which is normally closed and will open with a drop in temperature in the fast chill space to a preselected temperature such as 31 F.
  • an accelerated fast chill may be provided at the option of the user through a switch 64 for energizing a low wattage heater 66 located close to the thermostatic element 44 controlling the damper 42.
  • the optional arrangement of the switch 64 and heater 66 would be used only when an accelerated and deeper chill would not damage the articles being chilled, or other articles in the refrigerator compartment. Closing of switch 64 will result in heating of the element 44 so that the damper 42 will open beyond its normal position and thereby additional air can be admitted through the inlet passage 38 to the fan housing to decrease the temperature of the air discharged by the auxiliary fan 48.
