Description
SUPPORT ASSEMBLY FOR A REFRIGERATOR
STORAGE PAN
BACKGROUND OF THE INVENTIOl~T
This invention relates generally to refrigerator storage chambers, and more particularly, to a support assembly for a refrigerator storage pan.
A typical household refrigerator includes a freezer storage compartment and a fresh food storage compartment either arranged side-by-side and separated by a center mullion wall or over-and-under and separated by a horizontal center mullion wall. Storage shelves and storage drawers or pans typically are provided in the fresh food compartment, and storage shelves and wire baskets typically are provided in the freezer compartment. In some refrigerators, the storage pans may be maintained at a temperature that is different from the temperature of the compartment in which the storage pan is located. In addition, an ice maker may be provided in the freezer compartment. A freezer door and a fresh food door close the access openings to the freezer and fresh food compartments, respectively.
Storage pans are typically provided in a lower portion of the refrigerator for storing fresh fruits and vegetables or in some cases, fresh meats. The storage pans are generally suspended from a support structure that includes a track or glide that facilitates sliding movement of the storage pan in and out of the compartment.
While slide-out storage drawers and pans are desirable for convenient access, they can be difficult to use. In at least some known refrigerators, the storage pan can unexpectedly come all of the way out of its track, spilling the contents of the pan when a user tries to fully open the drawer. Alternatively, in other refrigerators, the travel of the storage pan is limited so that it doesn't easily come all of the way out, which limits access to the contents of the pan. Such pans may also be difficult to remove for cleaning.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 illustrates a side-by-side refrigerator 100 including a fresh food storage compartment 102 and freezer storage compartment 104. Freezer compartment I02 and fresh food compartment 104 are an-anged side-by-side. A
side-by-side refrigerator similar to refrigerator 100 is commercially available from General Electric Company, Appliance Park, Louisville, KY 40225.
Refrigerator 100 includes an outer case 106 and inner liners 108 and 110, A space between case 106 and liners 108 and 110, and between liners 108 and 110, is filled with foamed-in-place insulation. Outer case 106 normally is formed by folding a sheet of a suitable material, such as pre-painted steel, into an inverted U-shape to form top and side walls of case. A bottom wall of case 106 normally is formed separately and attached to the case side walls and to a bottom frame that provides support for refrigerator 100. Inner liners 108 and 110 are molded from a suitable plastic material to form freezer compartment 104 and fresh food compartment 106, respectively. Alternatively, liners 108, 110 may be formed by bending and welding a sheet of a suitable metal, such as steel. The illustrative embodiment includes two separate liners I08, 110 as it is a relatively large capacity unit and separate liners add strength and are easier to maintain within manufacturing tolerances. In smaller refrigerators, a single liner is formed and a mullion spans between opposite sides of the liner to divide it into a freezer compartment and a fresh food compartment.
A breaker strip I 12 extends between a case front flange and outer front edges of liners. Breaker strip I 12 is formed from a suitable resilient material, such as an extruded acrylo-butadiene-syrene based material (commonly referred to as ABS).
The insulation in the space between liners 108, 110 is covered by another strip of suitable resilient material, which also commonly is referred to as a mullion 1 I4. Mullion 114 also preferably is formed of an extruded ABS
material. It will be understood that i.n a refrigerator with separate mullion dividing an unitary liner into a freezer and a fresh food compartment, a front: face member of mullion corresponds to mullion I 14. Breaker strip I 12 and mullion I 14 form a front face, and extend completely around inner peripheral edges of case 106 and vertically between liners 108, 1 I0. Mullion 114, insulation between compartments, and a spaced wall of liners separating compartments, sometimes are collectively referred to herein as a center mullion wall 116.
Shelves 118 and slide-out drawers 120 normally are provided in fresh food compartment 102 to support items being stored therein. Refrigerator 100 also includes a bottom pan 122 that may be a part of a quick chill and thaw system (not shown in Figure I) that is selectively controlled, together with other refrigerator features, by a microprocessor (not shown in Figure 1) according to user preference via manipulation of a control infierface 124 mounted in an upper region of fresh food storage compartment I02 and coupled to the microprocessor. Shelves 126 and wire baskets 128 are also provided in freezer compartment I04. In addition, an ice maker 130 may be provided in freezer compartment I04.
A freezer door 132 and a fresh food door I34 close access openings to fresh food and freezer compartments 102, 104, respectively. Each door 132, I34 is mounted by a top hinge 136 and a bottom hinge (not shown) to rotate about its outer vertical edge between an open position, as shown in Figure I, and a closed position (not shown) closing the associated storage compartment. Freezer door 132 includes a plurality of storage shelves 138 and a sealing gasket 140, and fresh food door 134 also includes a plurality of storage shelves 142 and a sealing gasket 144.
Figure 2 is a partial cutaway view of fresh food compartment 102 illustrating storage drawers 120 stacked upon one another and positioned above a quick chill and thaw system 160. Quick chill and thaw system 160 includes an air handler 162 and pan 122 located adjacent a machinery compartment 164 (shown in phantom in Figure 2) to minimize fresh food compartment space utilized by quick chill and thaw system 160. A leading edge 368 of air handler 162 projects into pan 122. Storage drawers 120 are conventional slide-out drawers without internal temperature control. A temperature of storage drawers 120 is therefore substantially equal to an operating temperature of fresh food compartment 102. ~ottorn pan 122 is positioned slightly forward of storage drawers 120 to accommodate machinery compartment 164, and air handler 162 selectively controls a temperature of air in pan 122 and circulates air within pan 122 to increase heat transfer to and from pan contents fox timely thawing and rapid chilling, respectively, as described in detail below. When quick thaw az~d chill system 160 is inactivated, pan 122 reaches a steady state at a temperature equal to the temperature of mesh food compartment 102, and pan 122 functions as a third storage drawer. In alternative embodiments, greater or fewer numbers of storage drawers 120 and quick chill and thaw systems 160, and other relative sizes of quick chill pans 122 and storage drawers 120 are employed.
In accordance with known refrigerators, machinery compartment 164 at least partially contains components for executing a vapor compression cycle for cooling air. The components include a compressor (not shown), a condenser (not shown), an expansion device (not shown), and an evaporator (not shown) connected in series and charged with a refrigerant. The evaporator is a type of heat exchanger which transfers heat from air passing over the evaporator to a refi-igerant flowing through the evaporator, thereby causing the refrigerant to vaporize. The cooled air is used to refrigerate one or more refrigerator or freezer compartments.
Figures 3A and 3~ are perspective exploded viev~rs illustrating a bottom pan assembly that includes bottom pan 122. Pan 122 includes opposite side walls 182, a bottom wall 184 extending between side walls 182 and a rear wall including a cutout portion 187 for receiving air handler leading edge 168. Pan side walls 182 each include an outwardly projecting support member 188. Rear wall includes rearward facing engagement tabs 190. A mounting groove 191 is formed in a forward edge 192 of bottom wall 184. A window 194 fabricated from a transparent material is received in a cover 196 that is attached to a front 198 of pan 122. Cover 196 includes an outwardly curved handle 200 for user manipulation to open and close pan 122.
When pan 122 is in a closed position, pan 122 is covered by a stationary cover assembly 210. Cover assembly 210 is attached to the interior of the refrigerator fresh food compartment 102. Cover assembly includes cover top 212 and a seal frame member 214. Rear gaskets 216, a front gasket 218, and side cover gaskets 220 are provided to facilitate sealing pan 122, particularly during operation of the quick chill and thaw system.
Bottom pan I22 is supported by a support assembly 250 that facilitates extension and retraction of pan 122 from fresh food compartment 102. Support assembly 2S0 includes a wire frame 252, and right and left brackets 254, which in an exemplary embodiment are substantially identical. Bottom pan 122 is received within wire frame 252 for snap fit engagement as will be described. Wire frame 2S2 is continuously formed and includes spaced apart right and left side arms 260 and respectively. Front leg members 264 extend downwardly from forward ends 266 and 268 of side arms 260 and 262 respectively, and are joined by a front cross member 270. A rear cross member 272 connects rearward ends 276 and 278 of side arms and 262 respectively. Rear cross member 272 includes pan mounting sections 280.
Rear cross member 272 is formed to substantially conform to cutout portion 187 in rear wall 186.
Right side arm 260 includes a U-shaped member 284 attached thereto and defining a channel 286 between U-shaped member 284 and right side arm 260.
U-shaped member 284 and channel 286 define a mounting location for right bracket 254. Left side arm 262 includes a pair of hooks 290 attached thereto that define a mounting location for left bracket 254.
A slide assembly 300 is coupled to each bracket 254. Slide assemblies 300 facilitate sliding movement of pan 122 out of and into fresh food compartment 102. Each slide assembly 300 is of well known construction and includes a slide pan 302, a slide liner 304 and a slide spacer 306. Slide pan 302 is coupled to bracket 254 while slide liner 304 and slide spacer 306 are attached to an interior wall of fresh food compartment 102. Slide assembly 300 is a full extension slide assembly that allows easy access to the contents of pan 122.
Figure 4 illustrates bracket 254 in detail. Bracket 254 includes a generally C-shaped channel 320 that includes a side wall 322, a first -rail 324 and an opposite second rail 326. First rail 324 includes apertures 328 and a lip 330.
Apertures 328 are positioned on first rail 324 so as to coincide with and receive hooks 290 on left side arm 262. Second rail 326 includes slots 332 and a lip 334.
Slots 332 extend across the width of rail 326 and also through lip 334 such that rail 326 is formed with a center section 340 between a pair of end sections 342. Center rail section 340 is sized to be received in channel 286 of right side arm 260.
The operation of pan support assembly 250 will be described with reference to Figures 5 and 6. Brackets 254 are used in pairs and are mounted on right side arm 260 (Figure 5) and left side arm 262 (Figure 6) inversely oriented from each other, that is, on right side arm 260, rail 326 is the upper rail, while on left side arm 262, rail 324 is the upper rail. It is to be understood that in alternative embodiments, this relationship could be reversed.
With reference to Figure 5, bracket 254 is mounted on right side arm 260 by placing lip 334 of center rail section 340 into channel 286 and rotating bracket 254 in the direction of arrow A so that bracket 254 is suspended. from U-shaped member 284. Thus, bracket 254 is mounted on right side arm 260 without tools.
Conversely, bracket 254 is removable from right side arm 260 without tools, With reference to Figure 6, bracket 254 is mounted on left side arm 262 by inserting hooks 290 into apertures 328 in rail 324 and rotating bracket 254 in the direction of arrow B so that bracket 254 is suspended from hooks 290.
Thus, bracket 254 is also mounted on left side arm 262 without tools and similarly is removable from left side arrn 262 without tools.
Bottom pan 122 is received within wire frame 252 with support members 188 resting on wire frame side arms 260 and 262. Pan rear wall engagement tabs 190 engage mounting sections 280 of wire frame rear cross member 272 providing rearward support for bottom pan 122. Wire frame front cross member is received in snap fit engagement with groove 191 in forward edge 192 of bottom wall 184 thus securing pan 122 in wire frame 252. Thus bottom pan 122 is also installed in wire frame 252 without tools.
Figure 7 and 8 illustrate an alternative embodiment of a wire frame 452 support for bottom pan 122. Wire frame 452 is used in conjunction with right and left support brackets 254 as shown in detail in Figure 4. Wire frame 452 includes a right side arm 460 and a left side arm 462 and right and left front legs 464 and 465 respectively that extend downwardly from right and left side arms 460 and 462.
Right side arm 460 and left side arm 462 include U-shaped members 484 and 485 respectively and channels 486 and 487 respectively fox mounting support brackets 254. Right side arm 460 and right front leg member 464 deftne a plane 492 that includes right U-shaped member 484. In other words, right side arm 460 and right front leg member 464 form a right front portion and U-shaped member 484 is aligned with the right front portion. Left side arm 462 and left front leg member 465 form a left front portion which defines a plane 494. U-shaped anember 4$5 of left side arm 462 extends exterior from plane 494 in the direction of arrow C. Ire other respects, wire frame 452 is similar to wire frame 252, previously described.
For right side arm 460, support bracket 254 is mounted as described above with respect to right side arm 260 and with reference to Figure 5. For left side arm 462, support bracket 254 is mounted as shown in Figure 8. Bracket 254 is mounted on left side arm 462 by placing lip 334 of center rail section 340 into channel 487 and rotating bracket 254 in the direction of arrow D so that bracket 254 is suspended from U-shaped member 485.
_g_ The embodiments thus described provide a bottom pan support assembly that can be easily removed and installed by an end user and requiring no tools for disassembly and assembly. The design is robust and reliable and easy to maintain. The assembly uses few parts which, when combined with simple installation without tools, lowers production costs. Additionally, service technicians require no extra taols to service the assembly.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that tlae invention can be practiced with modification within the spirit and scope of the claims.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 illustrates a side-by-side refrigerator 100 including a fresh food storage compartment 102 and freezer storage compartment 104. Freezer compartment I02 and fresh food compartment 104 are an-anged side-by-side. A
side-by-side refrigerator similar to refrigerator 100 is commercially available from General Electric Company, Appliance Park, Louisville, KY 40225.
Refrigerator 100 includes an outer case 106 and inner liners 108 and 110, A space between case 106 and liners 108 and 110, and between liners 108 and 110, is filled with foamed-in-place insulation. Outer case 106 normally is formed by folding a sheet of a suitable material, such as pre-painted steel, into an inverted U-shape to form top and side walls of case. A bottom wall of case 106 normally is formed separately and attached to the case side walls and to a bottom frame that provides support for refrigerator 100. Inner liners 108 and 110 are molded from a suitable plastic material to form freezer compartment 104 and fresh food compartment 106, respectively. Alternatively, liners 108, 110 may be formed by bending and welding a sheet of a suitable metal, such as steel. The illustrative embodiment includes two separate liners I08, 110 as it is a relatively large capacity unit and separate liners add strength and are easier to maintain within manufacturing tolerances. In smaller refrigerators, a single liner is formed and a mullion spans between opposite sides of the liner to divide it into a freezer compartment and a fresh food compartment.
A breaker strip I 12 extends between a case front flange and outer front edges of liners. Breaker strip I 12 is formed from a suitable resilient material, such as an extruded acrylo-butadiene-syrene based material (commonly referred to as ABS).
The insulation in the space between liners 108, 110 is covered by another strip of suitable resilient material, which also commonly is referred to as a mullion 1 I4. Mullion 114 also preferably is formed of an extruded ABS
material. It will be understood that i.n a refrigerator with separate mullion dividing an unitary liner into a freezer and a fresh food compartment, a front: face member of mullion corresponds to mullion I 14. Breaker strip I 12 and mullion I 14 form a front face, and extend completely around inner peripheral edges of case 106 and vertically between liners 108, 1 I0. Mullion 114, insulation between compartments, and a spaced wall of liners separating compartments, sometimes are collectively referred to herein as a center mullion wall 116.

Quick chill and thaw system 160 includes an air handler 162 and pan 122 located adjacent a machinery compartment 164 (shown in phantom in Figure 2) to minimize fresh food compartment space utilized by quick chill and thaw system 160. A leading edge 368 of air handler 162 projects into pan 122. Storage drawers 120 are conventional slide-out drawers without internal temperature control. A temperature of storage drawers 120 is therefore substantially equal to an operating temperature of fresh food compartment 102. ~ottorn pan 122 is positioned slightly forward of storage drawers 120 to accommodate machinery compartment 164, and air handler 162 selectively controls a temperature of air in pan 122 and circulates air within pan 122 to increase heat transfer to and from pan contents fox timely thawing and rapid chilling, respectively, as described in detail below. When quick thaw az~d chill system 160 is inactivated, pan 122 reaches a steady state at a temperature equal to the temperature of mesh food compartment 102, and pan 122 functions as a third storage drawer. In alternative embodiments, greater or fewer numbers of storage drawers 120 and quick chill and thaw systems 160, and other relative sizes of quick chill pans 122 and storage drawers 120 are employed.
In accordance with known refrigerators, machinery compartment 164 at least partially contains components for executing a vapor compression cycle for cooling air. The components include a compressor (not shown), a condenser (not shown), an expansion device (not shown), and an evaporator (not shown) connected in series and charged with a refrigerant. The evaporator is a type of heat exchanger which transfers heat from air passing over the evaporator to a refi-igerant flowing through the evaporator, thereby causing the refrigerant to vaporize. The cooled air is used to refrigerate one or more refrigerator or freezer compartments.
