Abstract

A refrigeration appliance including a compartment for storing food items. A partition divides the compartment into a first and a second compartments. The first compartment is disposed horizontally adjacent the second compartment and has a user-selectable target freezer temperature. An evaporator is disposed in the first compartment. An evaporator fan is disposed in the first compartment for conveying cooling air from the evaporator to the first and the second compartments. A temperature control module positioned in the second compartment. The temperature control module includes a body having front and rear surfaces. An air passage is formed in the body and extends between a side inlet opening of the body to at least one outlet opening on the front surface of the body. A heater assembly is disposed between the front and the rear surfaces of the body for heating air in the air passage.

a heater assembly disposed proximate to the air passage, wherein air in the air passage is heated by the heater assembly when the heater assembly is energized.

2 . The refrigeration appliance according to claim 1 , wherein the heater assembly includes an electrical coil.

3 . The refrigeration appliance according to claim 1 , wherein the heater assembly is overmolded into the body.

4 . The refrigeration appliance according to claim 1 , wherein the body includes a front portion and a rear portion and at least a portion of the air passage is defined between the rear portion and the front portion.

5 . The refrigeration appliance according to claim 4 , wherein the at least a portion of the air passage is defined by a recess formed in at least one of the front portion and the rear portion.

6 . The refrigeration appliance according to claim 4 , wherein the heater assembly is embedded within at least one of the front portion and the rear portion.

7 . The refrigeration appliance according to claim 1 , wherein the air passage includes a second inlet opening extending through the front surface of the body.

8 . The refrigeration appliance according to claim 1 , further comprising a circulation fan positioned in the air passage for conveying air therealong.

9 . The refrigeration appliance according to claim 1 , wherein the air passage defines a closed loop circulation path with the second compartment.

10 . The refrigeration appliance according to claim 1 , further comprising:

a fresh food compartment disposed above the compartment, the fresh food compartment for storing food items in a refrigerated environment having a target temperature above zero degrees Centigrade.

11 . A refrigeration appliance comprising:

a compartment for storing food items in a refrigerated environment;

a partition dividing said compartment into a first compartment and a second compartment, said first compartment disposed horizontally adjacent said second compartment, said first compartment having a user-selectable target freezer temperature, said second compartment having a user-selectable target variable climate zone temperature between a predetermined temperature below 0 degrees Centigrade and a predetermined temperature above 0 degrees Centigrade, the partition defining a through passage between the first compartment and the second compartment;

an evaporator disposed in the first compartment;

an evaporator fan disposed in the first compartment for conveying cooling air from the evaporator to the first compartment and the second compartment; and

a temperature control module positioned in the second compartment, the temperature control module comprising:

a body having a front surface and a rear surface, the rear surface facing a rear wall of the second compartment and the front surface facing an open end of the second compartment,

an air passage formed in the body extending between a side inlet opening of the body and at least one outlet opening on the front surface of the body, the side inlet opening of the air passage aligned with the through passage in the partition between the first compartment and the second compartment,

a second inlet opening extending through the front surface of the body to the air passage, and

a damper assembly positioned proximate the air passage, the damper assembly comprising:

a frame assembly defining a damper air passage through the damper assembly fluidly communicating with the air passage formed in the partition, and a door rotatably attached to the frame assembly, the door moveable between a first position and a second position,

wherein when the door is in the first position the door fluidly isolates the through passage in the partition from the first compartment while allowing the second inlet opening in the body to fluidly communicate with the air passage in the body, and when the door is in the second position the door fluidly isolates the second inlet opening in the body from the air passage in the body while allowing the through passage in the partition to fluidly communicate with the first compartment.

12 . The refrigeration appliance according to claim 11 , wherein the air passage forms a closed loop circulation path within the second compartment when the door is in the first position.

13 . The refrigeration appliance according to claim 11 , wherein the air passage directs cooled air into the second compartment from the evaporator when the door is in the second position.

14 . The refrigeration appliance according to claim 11 , wherein the air passage is a single conduit extending between the first compartment and the second compartment.

15 . The refrigeration appliance of claim 11 , wherein the partition is not part of a uniform expanding foam material applied to a space between a liner and a metal shell of the refrigeration appliance.

16 . The refrigeration appliance according to claim 11 , further comprising:

a liner defining the compartment for storing food items in a refrigerated environment, a rear wall of the liner contoured to define a first horizontal recess therein; and

the partition including:

a protrusion extending from a rear edge of the partition, the protrusion disposed in the first horizontal recess in the liner when the partition is positioned in the compartment,

an opening extending through the protrusion between opposite side surfaces of the partition, the opening aligned with the first horizontal recess in the liner, and

the side inlet opening of the body fluidly communicating with the first horizontal recess in the liner and the opening extending through the partition,

wherein the evaporator fan disposed in the first compartment conveys cooling air from the evaporator through the opening extending through the partition, through the side inlet opening in the body, through the air passage in the body, through the at least one outlet opening in the body and exhausts the cooling air into the second compartment.

17 . The refrigeration appliance of claim 16 , wherein the liner is contoured to define a second horizontal recess fluidly connecting the first compartment and the second compartment, wherein air drawn by the evaporator fan in the first compartment is drawn from the second compartment through the second horizontal recess.

18 . A refrigeration appliance comprising:
