Definitions

  • the present invention relates generally to refrigerators, and more particularly to an air tower mounted to a liner in the fresh food compartment of a refrigerator.
  • Refrigerator liners and air towers are known and used in many different applications.
  • the fresh food compartment of a refrigerator may include a liner with an air distribution means mounted to the liner.
  • Conventional air ducts for transporting cold air from the freezer compartment to the fresh food compartment include an air duct formed in the foam insulation between the fresh food compartment and the freezer compartment.
  • Pre-foam support members must be installed to support shelves and drawers within the fresh food compartment.
  • an air duct that may be installed after foaming has occurred.
  • the flow of cool air into the fresh food compartment can be obstructed. This may occur because cool air falls to the bottom of the fresh food compartment, making it difficult to circulate the cool air near the top. Therefore, there is a continuing need for an air duct that promotes cool air circulation within the fresh food compartment even when filled with perishable items.
  • a refrigeration appliance comprising a freezer compartment maintaining air at a temperature of zero degrees Centigrade or less and a fresh food compartment maintaining air at a temperature greater than zero degrees Centigrade, an opening between the freezer compartment and fresh food compartment, the opening configured to allow air to flow from the fresh food compartment to the freezer compartment, an air tower adapted to be located within the fresh food compartment, the air tower configured to be in fluid communication with the fresh food compartment and freezer compartment, and a damper door adapted to be secured within the air tower and configured to pivot between a closed position and an open position, wherein the closed position of the damper door partially restricts flow through the air tower.
  • air is adapted to flow from the freezer compartment through the air tower and into the fresh food compartment before flowing through the opening from the fresh food compartment to the freezer compartment
  • a refrigeration appliance comprising a freezer compartment maintaining air at a temperature of zero degrees Centigrade or less and a fresh food compartment maintaining air at a temperature greater than zero degrees Centigrade, an opening between the freezer compartment and fresh food compartment, the opening configured to allow air to flow from the fresh food compartment to the freezer compartment, an air tower adapted to be located within the fresh food compartment, the air tower configured to be in fluid communication with the fresh food compartment and freezer compartment, wherein the air tower includes a connection means for removably attaching the air tower to a wall of the fresh food compartment, and

Still further, in the drawings, the same reference numerals are employed for designating the same elements.
  • the present invention relates generally to a refrigerator 2 including a freezer compartment 4 located in the lower portion of the refrigeration appliance.
  • the freezer compartment 4 may be accessed through a bottom mounted pull-out freezer door 6 .
  • the freezer compartment 4 is used to freeze and/or maintain food articles stored within in a frozen condition.
  • the freezer compartment 4 may be maintained at an air temperature at or below zero degrees Centigrade.
  • the upper portion of the refrigerator 2 includes a fresh food compartment 8 .
  • the fresh food compartment 8 may be used to keep food articles fresh and maintain an air temperature near and above zero degrees Centigrade.
  • the interior of the fresh food compartment of the refrigerator 2 includes an air tower 10 secured to the back of the fresh food compartment 8 to the rear wall of a liner 12 .
  • the interior is shown with tubing comprising a water tank. This tubing may be concealed by a mounting structure, such as a shelf, drawer, etc. and may be used to provide water to a water dispenser, ice dispenser, etc.
  • the bottom of the fresh food compartment comprises a floor 14 .
  • the floor 14 may also include inlet openings 16 .
  • the inlet openings 16 may serve as air ducts that direct air from the fresh food compartment to the freezer compartment below. Air that has circulated through the fresh food compartment may return to the freezer through the inlet openings 16 .
  • the floor 14 may also include an exhaust opening 18 .
  • the exhaust opening 18 serves as an air duct in the floor through which cold air from the freezer compartment is directed to the fresh food compartment.
  • the floor 14 of the fresh food compartment may be recessed in the center. Liquid spills from the fresh food compartment may occur, originating from spillage of items, condensation buildup, etc. and may lead to liquid buildup.
  • the floor 14 is recessed to accommodate for this liquid buildup.
  • the floor 14 may be recessed only in the center with raised margins at the sides, the front, and the rear wall of the fresh food compartment floor.
  • the recessed portion of the floor 14 may be lower than the inlet openings 16 and the exhaust opening 18 .
  • the recess 14 serves to confine any liquid that is on the floor and may be designed to have varying volumetric capacities, such as holding one gallon of liquid.
  • Having the center of the floor 14 recessed minimizes the likelihood that any of the liquid would spill over and enter either of the openings 16 , 18 . Similarly, the recessed center of the floor 14 reduces the chances of pooled liquid dripping from the front of the refrigerator compartment.
  • the air tower 10 can be secured to the liner 12 by an attachment means, which may include fasteners, screws, etc. which will be discussed later with reference to FIG. 7 .
  • the air tower 10 is open at the back and mounted to the rear wall of the liner 12 such that the rear wall closes off the back of the air tower 10 so as to form a duct through which air may pass. Consequently, air passing through the air tower 10 will be bounded at the back by the rear wall of the liner 12 and bounded at the front by the air tower 10 .
  • the air tower 10 includes an upper portion 24 that may be divided into two separated air passageways 26 .
  • Each air passageway 26 is in air flow communication with a lower portion 22 of the air tower 10 .
  • An access door 23 may be formed in the lower portion 22 of the air tower 10 .
  • the air tower 10 may also include an open space 28 that lies between the separated passageways 26 .
  • a mounting structure, such as a bracket, ladder etc. (not shown) may be inserted and secured to the open space 28 .
  • the liner 12 may include holes, as shown in FIG. 1 , to support a mounting structure, such as a shelf, drawer, etc. that is mounted centrally to the real wall of the liner 12 .
  • the air tower 10 will not interfere with the installation of shelves within the fresh food compartment.
  • the upper portion 24 of the air tower 10 may be provided with openings 20 . These openings 20 allow cool air from the freezer compartment to pass upwardly through the air tower 10 and to be discharged through from the air passageways 26 to the openings 20 and into the interior of the fresh food compartment 8 .
  • the openings 20 may be formed on each air passageway 26 . While there are two openings shown on each air passageway 26 , it is to be understood that there may be any number of openings in various shapes and sizes.
  • An aperture 29 may be formed at the top of the upper portion 24 .
  • a plurality of air-directing fins 36 may be included at the top of the air tower 10 to direct air that passes over the openings 20 but does not leave the openings 20 .
  • the air tower and rear wall of the liner 12 form a duct through which air can pass.
  • the air-directing fins 36 are formed at the top of the air tower 10 near the aperture 29 . Air may pass through the air passageways 26 , and be directed towards the aperture 29 at the top of the fresh food compartment 8 .
  • the fins 36 may be angled so as to direct and distribute air across the top of the fresh food compartment as it exits the aperture 29 .
  • the air-directing fins 36 may be included to direct air laterally across the top of the fresh food compartment 8 and ensure that air is substantially spread across the fresh food compartment. It is to be understood, however, that the size and quantity of air-directing fins 36 is variable, however, and may include more or less fins than shown in the example.
  • the air tower 10 may further include a support ledge 32 having a plurality of ribs 34 .
  • the support ledge 32 may be formed at the intersection of the upper portion 24 and lower portion 22 of the air tower 10 .
  • the ribs 34 of the support ledge 32 act to create a supporting surface for the rear portion of a mounting structure, such as a drawer, shelf, etc. (not shown).
  • a mounting structure such as a drawer, shelf, etc. (not shown).
  • the lower portion 22 of the air tower is shown more clearly in FIG. 4 .
  • the lower portion 22 may include one or more dampers 30 that may control the flow of air through the lower portion 22 .
  • the damper 30 may be positioned within the lower portion 22 of the air tower 10 and is designed to control the flow of air between the freezer compartment 4 and fresh food compartment 8 .
  • the damper 30 may be attached in the air duct between such that it is bounded in the rear by the liner 12 and in the front by the air tower 10 .
  • the damper may be accessed by removing the access door 23 in the lower portion 22 of the air tower 10 .
  • a stepper motor (not shown) may also be accessed by removing the access door 23 .
  • the damper 30 may include a damper door 40 , damper door frame 42 , and an opening 44 through which air may pass.
  • the damper door 40 When the damper door 40 is open, moisture from the fresh food compartment may accumulate on the damper door frame 42 . If the damper door 40 is then closed all the way to a horizontal orientation, the damper door 40 may rest on the moisture-soaked damper door frame 42 and freeze shut. To reduce the risk of freezing, the damper door 40 may form an angle from the conventional fully horizontal closed position. The angle of the fully closed position may be, for instance, 9°.
  • the open/closed position of the damper door 40 may be controlled by a stepper motor (not shown). Therefore, the fresh food and freezer compartments may be in fluid communication even when the damper door 40 is in its fully closed position.
  • the damper door 40 may not contact the frame 12 when in a fully closed position.
  • the stepper motor may be prompted by a user, electronic control, etc. to open and close, thus allowing more or less cold air from the freezer to pass through. For instance, if a sensor detects that the temperature in the fresh food compartment is too high, it may prompt a control to open the damper door 40 by the stepper motor.
  • the liner 12 may include threaded holes to receive threaded fasteners, such as screws or the like.
  • the liner 12 may also include apertures for the insertion of snap fasteners.
  • the air tower 10 includes a flange 46 and snap fasteners 48 .
  • the flange 46 has a hole in it to receive the screws that will attach the tower 10 to the liner 12 .
  • the air tower 10 may have one or more snap fasteners 48 extending from a side of the air tower adjacent to the flange 46 .
  • the snap fasteners 48 are inserted into open holes within the liner 12 such that the tower 10 does not have to be manually held in place.
  • the flange 46 may be aligned such that the hole in the flange 46 is positioned next to the threaded hole in the liner 12 .
  • a screw may then be inserted into the hole of the flange 46 and screwed into the threaded hole in the liner 12 , thus securing the air tower 10 in place.
  • the air tower 10 functions by allowing cool air from the freezer compartment 4 to pass to the fresh food compartment 8 .
  • Cool air from the freezer compartment 4 enters the air tower 10 in the freezer and passes through the damper 30 .
  • An air moving device, evaporator fan, or the like may also be provided for providing an upward pressure to the cool air.
  • the cool air After passing through the damper 30 , the cool air, under the impetus of the air moving device, passes upwardly through the two separated passageways 26 . Some of the upwardly-moving cool air may be discharged to the interior of the fresh food compartment 8 through the openings 20 . The remaining cool air that does not pass through the openings 20 is directed by fins 36 and discharged through the aperture 29 at the top of the air tower 10 .
  • the discharged air leaves the aperture 29 and enters the upper portion of the interior of the fresh food compartment.
  • the discharged air then descends into the interior of the fresh food compartment and cools food items located there. This arrangement ensures that items throughout the fresh food compartment, including those at the upper portion of the fresh food compartment are adequately cooled.
