## Abstract

A refrigerator has freezing and cooling compartments, and a cooling device disposed in a space between those compartments. The cooling device includes a refrigerant-conducting pipe arrangement. Attached to that pipe arrangement is a deodorizer comprised of an odor adsorbing element and a heater for heating the odor adsorbing element. The deodorizer is suspended from pipe sections of the pipe arrangement so as to extend transversely relative to a direction of air flow through the cooling device. The cooling device includes a defrosting heater actuated simultaneously with the deodorizer heater so that both heaters perform a defrosting function.

## Claims

### Claim 1

A refrigerator comprising:
a freezing compartment;
a cooling compartment disposed in vertically spaced relationship to said freezing compartment to form a space therebetween;
a cooling system disposed in said space and defining air inlet and outlet ends, said cooling system including a refrigerant-circulating pipe arrangement having pipe sections extending transversely relative to a direction of air travel through said cooling system, and a defrosting heater;
a circulating mechanism for circulating air from said freezing and cooling compartments through said cooling system;
a deodorizer unit arranged intermediate said inlet and outlet ends of said cooling system, said deodorizer unit including an odor adsorbing element, a heater for heating said odor adsorbing element to remove odors therefrom and a longitudinally extending projection at each end of said deodorizer unit, said heater of said deodorizer unit and said defrosting heater being simultaneously operable so that both of said heaters perform a defrosting function; and
a securing mechanism including a pair of hangers for suspending opposite ends of said deodorizer unit to said pipe arrangement such that said deodorizer unit extends transversely to said direction of air travel through said cooling system, each hanger including a pair of arms having hook-shaped upper portions for hooking onto respective pipe sections, and an upwardly open slot formed between said arms of each hanger for receiving a respective one of said projections.

### Claim 2 (depends on 1)

A refrigerator according to claim 1, wherein said arms of each hanger diverge upwardly.

### Claim 3 (depends on 1)

A refrigerator according to claim 1, wherein said slot is circular, and each projection and its respective hanger present mutually engageable surfaces for preventing rotation of said deodorizer unit about an axis defined by said projections.

### Claim 4 (depends on 1)

A refrigerator according to claim 1 including a heat reflector plate disposed over both said defrosting heater and said heater of said deodorizer unit.
