DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
Under certain circumstances, it may be desirable for a storage assembly to have a compartment with a dedicated refrigeration system. As an example, a storage assembly may include a number of drawers, one or more of which may be intended to store food or beverage items and the others for storing non-perishable goods in a non-refrigerated portion. While refrigerating the entire assembly may be feasible, doing so is not efficient and requires additional energy that would not otherwise be required. As such, it may be desirable to provide a compact refrigeration system that is specifically configured to only refrigerate a portion of the storage assembly, such as a drawer. One of the challenges associated with such a refrigeration assembly is integrating and insulating the drawer while maintaining useful storage space. The present disclosure aims to resolve this issue among others.
Referring to FIGS. 1-1A, a storage structure 10 including a body 12 and a number of drawers 14 is provided. The body 12 may be formed of non-insulated walls or panels that form a cavity that may receive the drawers 14. One or more of the drawers 14 may be a refrigerated drawer assembly 16 that may include an insulated cabinet 22 disposed in the cavity of the storage structure 10. The insulated cabinet 22 may define a refrigerated compartment and 24 a drawer 26 of the drawer assembly 16 may be selectively disposed in the refrigerated compartment 24. As an example, the drawer 26 may move from a retracted or closed position (e.g., see position 27 in FIG. 15 ), in which the drawer 26 is disposed in the refrigerated compartment 24, and a deployed or open position (e.g., see position 29 in FIG. 15 ), in which the drawer 26 is positioned outside of the refrigerated compartment 24 to allow access to a storage space 28 (FIG. 2 ) formed by the drawer 26. The drawer assembly 16 may include a front insulated panel 20 that may be fixed to a portion, such as a front wall 32, (FIG. 2 ) of the drawer 26. Additionally or alternatively, the drawer assembly 16 may include an aesthetic or decorative panel 18 that may be fixed to the front insulated panel 20.
FIG. 2 illustrates a schematic view of the drawer assembly 16 according to one or more embodiments. The drawer assembly 16 may include a machine compartment 30 that may be positioned adjacent to the insulated cabinet 22. In one or more embodiments, the machine compartment 30 may house one or more heat exchangers or components that make up portions of a heat exchange system, including but not limited to a compressor, a fan, a thermoelectric device 34 and a drain catchment.
FIG. 3 illustrates a perspective view of a drawer assembly 100 according to one or more embodiments. The drawer assembly 100 includes the insulated cabinet 22 formed by insulated side panels 36, a rear insulated panel 38, and the front insulated panel 20. The thermoelectric device 34 may be fixed to the rear insulated panel 38 and one or more portions of the thermoelectric device 34 may extend into the refrigerated compartment 24 and the machine compartment 30. As an example, the thermoelectric device 34 may include a cold plate 40 that may be disposed in the refrigerated compartment 24 and a heat plate 42 that may be disposed in the machine compartment 30. The cold plate 40 and the heat plate 42 may operate by the Peltier effect in which an electric current flows through the device 34, so that the cool plate decreases in temperature and the hot plate increases in temperature. The heat plate 42 may be attached to a heat sink to absorb the excess heat from the heat plate. Additionally or alternatively, a first fan 44 may be fixed to the heat plate 42 and the first fan 44 may be configured to move hot air away from the refrigerated compartment 24.
FIG. 4 illustrates a perspective-exploded view of the drawer assembly 100. One or more sealing members such as passthrough grommet 46 and a passthrough gasket 48 may be provided between the rear insulated panel 38 and the thermoelectric device 34. As an example, the passthrough gasket 46 may be formed of one or more polymeric materials such as dynamically vulcanized polymer alloy composed of cured EPDM (ethylene propylene diene monomer) rubber (also known as Santoprene), polyvinyl chloride (PVC), or thermoplastic elastomer (TPE), or other material(s) as required.
FIG. 5 illustrates a perspective view of a portion of the drawer assembly 100. For purposes of clarity, the drawer 26 is not illustrated. In one or more embodiments, the thermoelectric device 34 may be fixed to the rear insulated panel 38 by one or more straps 56 that may be fixed, such as fastened, to the rear insulated panel 38. A bottom portion of the thermoelectric device 34 may be supported by a portion 50 of the passthrough grommet 46. The bottom portion 50 of the passthrough grommet 46 may define an opening that may receive a spout 52 of a drain funnel 54 that may be configured to collect condensation from the thermoelectric device 34. The spout 52 may extend into the machine compartment 30 and may be arranged to expel collected condensation to a drain catchment or drain pan 58 that may stow the collected condensation.
An insulated cabinet gasket 62 may be fixed to front portions of the insulated side panels 36 and insulated top and bottom panels 64, 66 that extend between the insulated side panels 36. When the drawer 26 (not illustrated) is in the retracted or closed position, the cabinet gasket 62 may surround an outer periphery of the front insulated panel 20. The insulated cabinet gasket 62 may be formed by one or more plastic or polymeric materials including but not limited to a thermoplastic elastomer material. One or more vents such as an air grille 68 may be fixed to a front portion of the drain pan 58. The air grille 68 may be configured to permit air flow into the drain pan 58 to prevent water or fluid held in the drain pan 58 from being stagnate. As another example, the air grille 68 may be configured to provide an outlet path in which heated air from the machine compartment 30, or the hot plate 42, or both may travel through.
One or more guides such as glide rails 60 may be fixed to one or more of the insulated side panels 36 and the drawer 26 may be fixed to a moveable portion of the glide rails so that the drawer may move, after application of a required force applied to the drawer, between the deployed or open position and the retracted or closed position.
FIG. 6 illustrates a partial cross-sectional view of the insulated drawer assembly 100. The insulated panels, including the insulated top panel 64 and the insulated bottom panel 66, may each be formed by an inner member such as a liner 70 and an outer member such as a wrapper 72 that may collectively form an insulating cavity 74 in which one or more insulating materials 76 may be disposed. It is generally contemplated that the insulation materials may be a glass-type material, a carbon-based powder, silicon oxide-based materials, fumed silica insulating gasses, and other insulation as required. The insulation materials 76 substantially fill the insulating cavity 74 forming a substantially continuous layer between the liner 70 and the wrapper 72. In one or more embodiments, the insulated cabinet gasket 62 may be fixed to an inner gasket 78 that may be fixed to the wrapper 72 of the insulated top panel 64. A bottom portion of the inner gasket 78 may be fixed to the liner 70 of the insulated bottom panel 66. The inner gasket 78 may define an opening and the insulated cabinet gasket 62 may be fixed to the inner gasket 78.
The insulated panels may be formed by creating or pulling a vacuum through the liner 70 and the wrapper 72 and the insulation material 76 disposed therebetween. This process removes air between the liner 70 and the wrapper 72 that may otherwise permit cold air to escape and hot air to enter in the refrigerated compartment. The passthrough grommet 46, passthrough gasket 48, and inner gasket 78, the liner 70, and wrapper 72 may be collectively configured to provide a sealed vacuum insulated structure for each of the insulated panels.
FIG. 6A illustrates a detailed magnified view taken of area A-A in FIG. 6 . As stated above, the insulated top panel 64 may be formed of the liner 70 and the wrapper 72. A rear portion of the liner 70 may include a liner flange 80 and a rear portion of the wrapper 72 may include a wrapper flange 82. The passthrough grommet 46 may include a main body portion 84 and a lip 86 that may extend from the main body portion 84 towards the front insulated panel 20. The liner flange 80 may be disposed on the lip 86 to sandwich the lip 86 to the thermoelectric device 34 (e.g., the liner flange 80 may force the lip 86 into contact with the thermoelectric device 34. More specifically, the liner flange 80 may sandwich the lip 86 (e.g., force the lip into contact with) to the cold plate 40 of the thermoelectric device 34. As an example, the passthrough grommet 46 may be formed of an elastic material such as an elastomer so that the lip 86 compresses when the liner flange 80 is disposed on the lip 86.
In one or more embodiments, the passthrough gasket 48 may include a horizontal wall 88, a first vertical wall 90, and a second vertical wall 92. A protrusion 94 may extend from the horizontal wall 88 and the protrusion 94 may be spaced apart from the first vertical wall 90 to form a space configured to receive the flange 82 of the wrapper 72 to fix the position of the wrapper 72 with respect to the thermoelectric device 34. The second vertical wall 92 may be fixed to the liner flange 80 by an adhesive such as an adhesive tape 96. The liner flange 80 may be fixed to the second vertical wall 92 prior to installing the insulation materials 76 or more specifically prior to applying a vacuum to install the insulation materials 76.
FIG. 7 illustrates an exploded view of the thermoelectric device 34 and the straps 56. As stated above, the first fan 44 may be fixed to a portion of the thermoelectric device 34 such as the heat plate 42. The straps 56 may engage an outer periphery of the cold plate 40 so that the thermoelectric device 34 is fixed to a portion of the insulated cabinet 22.
FIG. 8 illustrates a perspective view of an exemplary thermoelectric device 98 according to one or more embodiments. The thermoelectric device 98 may include the cold plate 40 and a heat plate 102, where the heat plate 102 is relatively wider than the cold plate 40. In one or more embodiments, a second fan 104 may be fixed to the cold plate 40. The thermoelectric device 98 may be fixed to the rear insulated panel 38 in a manner similarly described and illustrated in reference to FIGS. 6 and 6A.
FIG. 9 illustrates a top-schematic view of an exemplary drawer assembly 106. The drawer assembly 106 may include a refrigeration system 109 that may be provided with an evaporator 108. Generally, the evaporator 108 may be disposed between the rear insulated panel 38 and the drawer 26 (also shown in FIG. 15 ). In one or more embodiments, the evaporator 108 may be a roll-bond evaporator. The roll-bond evaporator 108 may be a plate cooler formed in such a way that a refrigerant tube, through which a refrigerant flows, is provided in an aluminum plate. The roll-bond evaporator 108 may include a refrigerant inlet through which a refrigerant is introduced and a refrigerant outlet through which the refrigerant is discharged. The roll-bond evaporator 108 may generate cold air to cool the insulated cabinet 22.
The drawer assembly 106 may include a base 116 that may support the insulated cabinet 22 and may form portions of the machine compartment 30 disposed rearward of the insulated cabinet 22. The base 116 may be configured to support a compressor 110, a drain pan 112, and a fan 114 each of which constitute portions of the refrigerator system 109.
FIG. 10 illustrates a schematic-side view of the drawer assembly 106 and FIG. 11 illustrates a side-plan view of the drawer assembly 106. In one or more embodiments, the refrigeration system 109 may include a condenser 118 that may be disposed between the base 116 and the drawer 26. As will be described in greater detail below, the condenser 118 may form a cold air supply path and a warm air return bath for the drawer assembly 106. The refrigeration system 109 may include a controller 122 that may be operatively coupled to the compressor 110 and the fan 114. As an example, the controller 122 may be configured to actuate one or more components of the refrigeration system 109 in response to input from a sensor e.g., a temperature sensor, drawer sensor, or any other sensor.
The controller 122 may include a memory provided with stored instructions that may be used to actuate the compressor 110, the fan 114 or other components of the refrigeration system 109, as required. As an example, the controller 122 may be configured to control the activation, duty cycle, and operation of the compressor 110.
The compressor 110 is configured to circulate and change refrigerant from a liquid state to a gas state by routing the refrigerant through the evaporator 108 so that the refrigerant undergoes an evaporation process in order to cool the air within the refrigerated space 24. During the evaporation process, heat is transferred to the refrigerant. After evaporating, the compressor 110 increases the pressure, an in turn, the temperature of the refrigerant. The gas refrigerant is then routed to the condenser 118 so that it is condensed into a liquid and the excess heat is rejected to the ambient surroundings. The process then repeats.
FIG. 12 illustrates a top-perspective view of the drawer assembly 106. As previously mentioned, the insulated cabinet 22 forms a refrigerated space 24 in which the drawer 26 (not illustrated) is stowed. The rear insulated wall 38 of the insulated cabinet 22 may be adjacent to the machine compartment 30. The evaporator 108 may be fixed to the rear insulated wall 38 of the insulated cabinet. In order to properly cool the refrigerated space 24, heat needs to be rejected to the ambient surroundings. This is accomplished by drawing air into the machine compartment 30 as well as the space between the drawer 26 and the base 116, across the compressor 110 and condenser 118 (FIG. 11 ). The fan 114 provides the driving force to move air through the machine compartment 30 and the space beneath the drawer 26 and above the base 116 where the condenser 118 is located.
The compressor 110 may be supported by the base 116 and positioned adjacent to the drain pain 112 and the fan 114. By positioning the compressor 110, drain pan 112, and the fan 114 in the machine compartment 30 and by positioning the evaporator 108 on the rear insulated panel 38 and the condenser 118 beneath the drawer 26, relatively little space is required from the refrigeration system 109. By minimizing space required for the refrigeration system 109 permits a larger refrigerated space 24.
FIG. 13 illustrates a top view of a portion of the drawer assembly 106. As mentioned above, the compressor 110 and drain pan 112 may each be disposed on the base 116 behind the rear insulated panel 38 of the insulated cabinet 22. In one or more embodiments, the controller 122 may be fixed to the rear insulated panel 38.
FIG. 14 illustrates a top-schematic view of the refrigeration system 109. The base 116 may include a first side 116 a and a second side 116 b. The compressor 110 may be arranged on the first side 116 a of the base 116. Whereas the drain pan 112 and condenser 118 may be disposed on the second side 116 b of the base 116. The arrangement of the compressor 110 and condenser 118 may form a warm air return pathway 126 and a cold air supply 128. Warm air may be directed from the compressor along the warm air return pathway 126 through the air grille 68. Cold air may be directed from ambient surroundings, through the air grille 68 (FIG. 5 ), past the condenser 118 to the drain pan 112. In one or more embodiments, a sound barrier such as sound insulation 124 may positioned adjacent to the condenser 118 and configured to mitigate noise generated by the condenser 118.
FIG. 15 illustrates a cross-sectional view of the drawer assembly 106. In one or more embodiments, the controller 122 may be fixed to the outer wrapper 72 by bracket 130. The bracket 130 may be L-shaped including a first leg and a second leg. The second leg may include an aperture and a portion of the controller 122 may extend through the aperture so that the controller 122 is fixed to the L-shaped bracket 130. As an example, the liner 70 may include a rear wall 132 that may extend in a vertical direction. The evaporator 108 may be fixed to the rear wall 132. The drawer 26 may include sidewalls 136 (only one of which is shown) that are connected to a rear wall 134 and a bottom wall 138. Because the drawer 26 is disposed in the refrigerated space 24, the sidewalls 136, rear wall 134 and the bottom wall 138 may be formed of a non-insulative material to permit refrigerated air to flow into the storage space 28 formed by the drawer 26.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
