Description

BACKGROUND OF THE INVENTION

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 arranged 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 pan. 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

FIG. 1 illustrates a side-by-side refrigerator 100 including a fresh food storage compartment 102 and a freezer storage compartment 104 are arranged 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, 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 106. 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 108, 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 112 extends between a case front flange and outer front edges of liners. Breaker strip 112 is formed from a suitable resilient material, such as an extruded acrylo-butadiene-styrene 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 114. Mullion 114 also preferably is formed from an extruded ABS material. It will be understood that in a refrigerator with separate mullion dividing a unitary liner into a freezer and a fresh food compartment, a front face member of mullion corresponds to mullion 114. Breaker strip 112 and mullion 114 form a front face, and extend completely around inner peripheral edges of case 106 and vertically between liners 108, 110. 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 FIG. 1) that is selectively controlled, together with other refrigerator features, by a microprocessor (not shown in FIG. 1) according to user preference via manipulation of a control interface 124 mounted in an upper region of fresh food storage compartment 102 and coupled to the microprocessor. Shelves 126 and wire baskets 128 are also provided in freezer compartment 104. In addition, an ice maker 130 may be provided in freezer compartment 104.

A freezer door 132 and a fresh food door 134 close access openings to fresh food and freezer compartments 102, 104, respectively. Each door 132, 134 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 FIG. 1, 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.

FIG. 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 to a machinery compartment 164 (shown in phantom in FIG. 2) to minimize fresh food compartment space utilized by quick chill and thaw system 160. A leading edge 168 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. Bottom pan 122 is positioned slightly forward of storage drawers 120 to accommodate machinery compartment 164, and air handler 162 selectively controls the air temperature of pan 122 and circulates air within pan 122 to increase heat transfer to and from pan contents for timely thawing and rapid chilling, respectively, as described in detail below. When quick thaw and chill system 160 is inactivated, pan 122 reaches a steady state at a temperature equal to the temperature of fresh 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 refrigerant flowing through the evaporator, thereby causing the refrigerant to vaporize. The cooled air is used to refrigerate one or more refrigerator or freezer compartments.

FIG. 3 is a perspective exploded view illustrating a bottom pan 122. Pan 122 includes opposite side walls 182, a bottom wall 184 extending between side walls 182, and a rear wall 186 including a cutout portion 187 for receiving air handler leading edge 168. Pan side walls 182 each includes an outwardly projecting mounting portion 188, and each mounting portion 188 further includes a plurality of openings 189 defined therethrough. Rear wall 186 includes rearward facing engagement tabs 190. 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 fresh food compartment 102. Cover assembly 210 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 quick chill and thaw system 160.

Bottom pan 122 is supported by a support assembly 250 that facilitates extension and retraction of pan 122 from fresh food compartment 102. Support assembly 250 includes right and left brackets 252, which in an exemplary embodiment are substantially identical. Brackets 252 may engage with side walls 182 of pan 122, respectively, to support pan 122 thereon. Brackets 252 are fabricated from a rigid material, such as, for example, a plastic material or a metal material.

A slide assembly 300 is coupled to each bracket 252. 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 252 while slide liner 304 and slide spacer 306 are attached to an interior wall of fresh food compartment 102. As such, bracket 252 is slidably coupled to fresh food compartment 102, and further, pan 122 is slidably coupled to fresh food compartment 102 when engaging brackets 252. Specifically, slide assembly 300 is a full extension slide assembly that allows easy access to the contents of pan 122.

FIG. 4 illustrates bracket 252 in detail. Bracket 252 includes a generally C-shaped channel 320 that includes a side wall 322, an upper wall 324, and a bottom wall 326 connecting with side wall 322. Bracket 252 also includes a retainer 328 mounted thereon for engaging pan 122.

In the exemplary embodiment, retainer 328 includes an elongated retainer bar 330 for mounting on upper wall 324 of bracket 252, and two locking mechanisms, more specifically, swing locks 332 mounted on retainer bar 330. Each swing lock 332 includes a retaining member 334 extending upward from retainer bar 330, and a tab 336 rotatably mounted on retaining member 334. In one embodiment, each tab 336 further includes a handle 338 extending outwardly from a free end thereof, and handle 338 may be held by an operator to rotate tab 336. In an alternative embodiment, retainer bar 330 is unitarily formed with bracket 252.

FIG. 5 is a perspective view of pan 122 mounted on bracket 252 shown in FIG. 3, and FIGS. 6 and 7 illustrate swing lock 332 positioned in a first position and a second position, respectively. In the exemplary embodiment, openings 189 are modified as two cut outs complementary in shape with swing lock 332 for allowing swing lock 332 to insert therethrough. When mounting pan 122 onto bracket 252, mounting portion 188 is put onto the top of bracket 252, retaining member 334 is inserted through and received in the corresponding opening 189, and tab 336 is exposed above mounting portion 188. In one embodiment, mounting portion 188 further includes a rim 340 extending downward therefrom, and rim 340 prevents swing lock 332 from moving laterally to disengage with mounting portion 188.

When swing lock 332 is positioned in the first position (shown in FIG. 6), tab 336 is positioned misaligned with opening 189, and mounting portion 188 is sandwiched between tab 336 and retainer bar 330, such that pan 122 is secured on bracket 252. When swing lock 332 is rotated to the second position (shown in FIG. 7) along the direction indicated as arrow A, tab 336 is positioned substantially aligned with opening 189, such that pan 122 may be lifted upward to disengage with swing lock 332. As such, swing lock 332 may be rotated to the first position to secure pan 122 on bracket 252, and may also be manually rotated to the second position to facilitate pan 122 mounting onto or being removed from bracket 252.

FIG. 8 illustrates an alternative embodiment of bracket 252 including a retainer 350 in lieu of retainer 328 (shown in FIG. 4). Retainer 350 includes an elongated retainer bar 352 for mounting on bracket 252, and a swing lock 354 having a retaining member 356.

Retainer 350 further includes a hook member 358 extending from retainer bar 352, and hook member 358 defines a receiving slot 360 for receiving a portion of mounting portion 188. Opening 189 is modified as a cut out complementary in shape with swing lock 332 for allowing swing lock 332 to be inserted therethrough. To mount pan 122 onto bracket 252, hook member 358 engages, and receives a portion of, mounting portion 188, retaining member 356 is inserted through opening 189, and swing lock 354 is then rotated to the first position to secure pan 122 thereon.

FIGS. 9 and 10 illustrate an alternative embodiment of bracket 252 which includes a retainer 370 in lieu of retainer 328 (shown in FIG. 4). Retainer 370 includes an elongated retainer bar 372 for mounting on upper wall 324 of bracket 252, a locking mechanism, more specifically, snap lock 374 formed on retainer bar 372, and a hook member 376 formed at an end of retainer bar 372 and structurally similar with hook member 358 (shown in FIG. 8). Snap lock 374 includes two bifurcated retaining members 378 extending upward from retainer bar 372 and arranged at a back-to-back relation. Each retaining member 378 includes an engaging protrusion 380 extending outward therefrom, and each engaging protrusion 380 has a slant surface 382 and a horizontal surface 384 connecting with slant surface 382.

Opening 189 is formed as a substantially rectangular aperture defined through mounting portion 188 to accommodate snap lock 374. When mounting pan 122 onto bracket 252, retaining members 378 are inserted into opening 189 and slant surface 382 facilitates the corresponding retaining member 378 bending inward to allow the insertion. After the insertion, snap lock 374 resiliently returns to the first position. A portion of retaining member 378 is then received in opening 189, and horizontal surface 384 of retaining member 378 engages mounting portion 188, such that pan 122 is retained by snap lock 374. In one embodiment, snap lock 374 is compressed by an operator such that retaining members 378 are resiliently deformed inward to the second position. Retaining members 378 disengage with opening 189 which facilitates removing snap lock 374 from opening 189. As such, snap lock 374 is positioned in the first position to lock pan 122 thereon, and may also be positioned in the second position to allow pan 122 to be removed therefrom.
