Refrigerator with through-the-door quick-chilling service

Claim 2

Refrigerator apparatus comprising: (a) a freezer compartment, (b) a quick-chilling chamber in association with the freezer compartment and having a first container section from outside the freezer compartment and a second air duct section, (c) air flow communication means between the first container section and freezer compartment, air flow communication means between the second air duct section and freezer compartment and air flow communication means between the first and second sections near the top thereof, (d) means for moving air from the freezer compartment in a path through one section then the other section of the quick-chilling chamber and back into the freezer compartment for a selectable period of time, (e) settable timing means to start and stop the means for moving air, and (f) thermal insulation between the quick-chilling chamber and the freezer compartment.

Claim 3

The refrigerator apparatus of claim 1 wherein the air flow communication means includes an air entrance opening and an air outlet opening with both openings located below the thermal insulation.

Claim 4

The refrigerator apparatus of claim 1 wherein the air flow path entering the quick-chilling chamber enters the first container section from the freezer compartment and is discharged from the second air duct section back into the freezer compartment.

Claim 5

The refrigerator aparatus of claim 1 wherein the air flow means is an electric motor driven blower.

Claim 6

The refrigerator of claim 4 wherein the blower is located at the bottom of the second air duct section and arranged to move air in a path from the freezer compartment into the first container section and from the second air duct section back into the freezer compartment.

Claim 7

The refrigerator apparatus of claim 1 wherein the quick-chilling chamber is thermally insulated such that when the means for moving the air in a path is inoperative, the temperature of the first container section rises and is maintained at above-freezing temperatures.

Claim 8

The refrigerator apparatus of claim 1 wherein means is provided for separating air flowing into the quick-chilling chamber and air flowing from the quick-chilling chamber back into the freezer compartment is separated to prevent substantial mixing of the entering and exiting air.

Claim 9

The refrigerator apparatus of claim 1 wherein the freezer compartment has an access door and the quick-chilling chamber is located on the interior of the access door and moveable with the door and the first container section access door is secured to the freezer compartment door.

Claim 10

The refrigerator apparatus of claim 1 wherein the first container section has an open grid support member and the thermal insulation between the quick-chilling chamber and the freezer compartment extends at least down to the support member.

Claim 11

Refrigerator apparatus comprising: (a) a freezer compartment, (b) a quick-chilling chamber in association with the freezer compartment and having a first container section with a door for access to the interior of the container section from the outside the freezer compartment and a second air duct section separated from the first section by apartition, (c) air flow communication means between the first container section and freezer compartment, air flow communication means between the second air duct section and freezer compartment, and air flow communication means through the partition between the first and second sections near the top thereof above the air flow communication means between the first container section and freezer compartment and the air flow communication means between the second air duct section and freezer compartment, (d) an electric motor-driven blower located near the bottom of the air duct section for moving air from the freezer compartment in a path through the first container section, the partition, and the second air duct section and back into the freezer compartment for a selectable period of time, (e) settable timing means to start and stop the blower, and (f) thermal insulation between the quick-chilling compartment and the freezer compartment such that when the electric motor-driven blower is inoperative, the temperature of the first container section rises and is maintained at above-freezing temperatures.

Claim 12

Refrigerator apparatus comprising: (a) a freezer compartment, (b) a quick-chilling chamber in association with the freezer compartment and having a first container section with a door for access to the interior of the container section from the outside the freezer compartment and a second air duct section separated from the first section by apartition, (c) air flow communication means between the first container section and freezer compartment, air flow communication means between the second air duct section and freezer compartment, and air flow communication means through the partition between the first and second sections near the top thereof above the air flow communication means between the first container section and freezer compartment and the air flow communication means between the second air duct section and freezer compartment, (d) an electric motor-driven blower located near the bottom of the air duct section for moving air from the freezer compartment in a path through the first container section, the partition, and the second air duct section and back into the freezer compartment for a selectable period of time, (e) settable timing means to start and stop the blower, and (f) thermal insulation between the quick-chilling compartment and the freezer compartment such that when the electric motor-driven blower is inoperative, the temperature of the first container section rises and is maintained at above-freezing temperatures.
