Description

Refrigeration appliance auxiliary evaporating tray technical field

The present invention generally relates to refrigeration appliances. In particular, the present invention relates to improved evaporation characteristics for refrigeration appliances.

Background technique

Refrigeration appliances typically include a cabinet defining one or more refrigerated compartments for receiving food items for storage. One or more thermally sealed doors are provided for selectively closing the food storage and refrigeration compartment. Typically, by pulling the door body, such as by pulling a handle on the door body, the door body can be moved between a closed position and an open position in order to access the food product stored therein.

Refrigeration appliances typically utilize a hermetic refrigeration system to cool the refrigerated compartment of the refrigeration appliance. A typical hermetic refrigeration system includes an evaporator, a condenser, and a fan. The fan generates air flow through the evaporator to cool the air flow. Cooling air is then provided into the refrigerated compartment through the opening to maintain the refrigerated compartment at the desired set point temperature. Air from the refrigerated compartment is circulated back through the return air duct to be re-cooled by the hermetic refrigeration system during operation of the refrigeration appliance, which maintains the refrigerated compartment at the desired temperature.

In some situations, such as when doors are opened, and particularly when doors are opened frequently and/or are held open for extended periods of time, relatively warm, watery air enters the refrigerated compartment. When this warm, watery air from the surrounding environment enters the refrigerated compartment, condensation forms on surfaces within the refrigerated compartment, such as walls and shelves. The condensed water droplets then evaporate, and during the operation of the sealed refrigeration system, the condensed water droplets are drawn to the evaporator coil where it freezes. The evaporator must then be regularly defrosted. Melt water from the evaporator defrost is usually collected in an evaporative pan at the bottom of the refrigeration appliance, from which the liquid water eventually evaporates and returns to the ambient air outside the refrigeration appliance.

However, typical evaporative pans may have insufficient volume to store large amounts of meltwater generated after use (eg, frequent and/or prolonged door openings, especially during warmer seasons and in warmer climates). In some cases, melt water may accumulate in the evaporation pan faster than it evaporates, to the point where the pan may overflow.

Accordingly, there is a need for a refrigerator with improved evaporation characteristics.

SUMMARY OF THE INVENTION

Various aspects and advantages of the invention will be set forth in the description that follows, or will be apparent from the description, or may be learned by practice of the invention.

As illustrated in FIGS. 1 and 2 , the exemplary refrigeration appliance 100 has an insulated housing or case 120 that defines a food storage compartment 122 . Door 124 is configured to selectively seal off food storage compartment 122 when in the closed position (FIG. 1) and provide access to food storage compartment 122 when in the open position (FIG. 2). The door body 124 is rotatably mounted to the case body 120, such as by one or more hinges 126 (FIG. 2), for rotation between the open and closed positions.

The refrigeration appliance 100 defines a vertical V, a lateral L, and a lateral T that are perpendicular to each other (eg, FIG. 7 ). As can be seen in FIGS. 1 and 2 , the box or housing 120 extends in the vertical direction V between the top 101 and the bottom 102 and in the lateral direction L between the left side 104 and the right side 106 , and extends along the transverse direction T between the front portion 108 ( FIG. 2 ) and the rear portion 110 ( FIG. 7 ). As can be seen in FIG. 2 , the food storage compartment 122 includes a front portion 134 . The front 134 of the food storage compartment 122 defines an opening 136 for receiving food. The food storage compartment 122 is a refrigerated compartment 122 for receiving food for storage. As used herein, the chamber may be "cooled" in that the chamber may operate at temperatures below room temperature (eg, less than about seventy-five degrees Fahrenheit (75°F)). One of ordinary skill in the art will recognize that the food storage compartment 122 may be cooled by a sealed refrigeration system such that the food storage compartment 122 may operate at or near the temperatures described herein by providing cool air from the sealed refrigeration system. One of ordinary skill in the art understands the structure and function of such a sealed refrigeration system, and for the sake of brevity and clarity, it will not be described in further detail herein.

The refrigerator door 124 is rotatably mounted (eg, hinged) to the edge of the case 120 for selective access to the fresh food compartment 122 within the case 120 . The refrigerator door 124 may be mounted to the bin 120 at or near the front 134 of the food storage compartment 122 such that the door 124 is moved between a closed position ( FIG. 1 ) and an open position ( FIG. 2 ), eg, rotated via hinge 126 . In the closed position of FIG. 1 , the door body 1 hermetically closes the food storage compartment 122 . Additionally, one or more gaskets and other sealing devices may be provided to facilitate sealing between the door body 124 and the box body 120, which are not shown, but will be understood by those of ordinary skill in the art. In the open position of FIG. 2 , door 124 allows access to food preservation compartment 122 .

For example, as shown in FIG. 2, various storage components may be installed within the food storage compartment 122 to facilitate storage of food products therein, as will be understood by those skilled in the art. In particular, the storage part includes a box 116 , a drawer 117 and a shelf 118 installed in the food fresh-keeping chamber 122 . Box 116, drawer 117, and shelf 118 are configured to receive food products (eg, beverages or/or solid food products) and may assist in organizing such food products.

As mentioned, the bin 120 defines a single refrigerated compartment 122 for receiving food items for storage. In this example, the single refrigerated compartment 122 is the food preservation compartment 122 . In some embodiments, the refrigerated compartment may be a freezer compartment, and/or the refrigerated appliance 100 may include one or more additional refrigerated compartments for receiving various food items and storing these at various different temperatures as desired food. For example, refrigeration appliance 100 may include one or more refrigeration compartments for deep freezing (eg, at about 0°F or lower) storage, or for storage at temperatures such as about 60°F or higher Cool for example a product or wine at a relatively warmer temperature and any suitable temperature in between the examples. In various exemplary embodiments, refrigeration compartment 122 may selectively operate at any number of various temperatures and/or temperature ranges as desired or required for each application, and/or refrigeration appliance 100 may include a One or more additional chambers optionally operating at any suitable food storage temperature.

The illustrated exemplary refrigeration appliance 100 is commonly referred to as a single door or special purpose refrigerator, and is sometimes referred to as a column refrigerator. However, it is recognized that the benefits of the present invention are applicable to other types and styles of refrigerators, such as bottom-mounted refrigerators, top-mounted refrigerators, side-by-side refrigerators, or freezer appliances. Accordingly, the description set forth herein is for purposes of example only, and is not intended to be limiting in any respect, eg, to a particular refrigerated compartment configuration. As another example, the term "refrigeration appliance" is not intended to be limited to appliances that only provide food preservation, or to appliances that provide food preservation at all. The term "refrigeration appliance" as used herein also includes appliances that provide both freshness and refrigerated storage of food or only refrigerated storage.

As shown in the schematic diagram in FIG. 3 , the refrigeration appliance 100 may include an evaporator 70 . Evaporator 70 may be in fluid communication with food storage compartment 122 such that cool dry air 1002 flows from evaporator 70 to food storage compartment 122 and warm moist air 1000 flows from food storage compartment 122 to evaporator 70 . As one of ordinary skill in the art will recognize, evaporator 70 may be part of a sealed refrigeration system that provides cold air to food storage compartment 122 as described above. The structure and function of such a refrigeration system are generally understood by those of ordinary skill in the art, it can be seen that the evaporator 70 is only schematically illustrated, and for the sake of brevity and clarity, the remaining components of the sealed refrigeration system are not described in further detail herein. example or description.

It should be understood that the terms "cold" and "warm" and "dry" and "wet" are each defined relative to the corresponding other. For example, the air 1002 from the evaporator 70 to the food storage compartment 122 is cooler than the air 1000 from the food storage compartment 122 to the evaporator 70, and the air 1000 from the food storage compartment 122 to the evaporator 70 is cooler than the air 1000 from the food storage compartment 122 to the evaporator 70 The air 1002 of the storage chamber 122 has a higher moisture content, eg, is more humid, and so on. As another example, the cold dry air 1002 from the evaporator 70 to the food storage compartment 122 may be cooler than ambient air (eg, air in the ambient environment around (eg, immediately outside) the refrigeration appliance 100 ). For example, the cool dry air 1002 from the evaporator 70 to the food storage compartment 122 may be at a temperature below room temperature, where room temperature is generally understood by those of ordinary skill in the art to include from about sixty-five degrees Fahrenheit (65°F) to about seventy-five degrees Fahrenheit (75°F) range, and the cold dry air 1002 from the evaporator 70 to the food storage compartment 122 may be at a temperature of about fifty degrees Fahrenheit (50°F) or less, such as about forty Five degrees Fahrenheit (45°F) or less. For example, in embodiments where the food storage compartment 122 is a food preservation compartment, the cold dry air 1002 from the evaporator 70 to the food storage compartment 122 may be at a temperature generally above the freezing point of water, such as at about thirty-five degrees Fahrenheit ( 35°F) to about fifty degrees Fahrenheit (50°F), such as between about forty degrees Fahrenheit (40°F) to about forty-five degrees Fahrenheit (45°F). As another example, in embodiments where the food storage compartment 122 is a freezer compartment or freezer, the cool dry air 1002 from the evaporator 70 to the food storage compartment 122 may be at a temperature generally below the freezing point of water, such as at about Between twenty degrees Fahrenheit (20°F) and about minus fifteen degrees Fahrenheit (-15°F), such as between about five degrees Fahrenheit (5°F) and about minus ten degrees Fahrenheit (-10°F) , such as about zero degrees Fahrenheit (0°F).

Referring again to FIG. 3 , the refrigeration appliance 100 may further include a melt water conduit 200 . As illustrated, the melt water conduit 200 may extend from the evaporator 70 to the auxiliary evaporation pan 202 of the refrigeration appliance 100 . Thus, in some embodiments, melt water conduit 200 may be in fluid communication with evaporator 70 and may be downstream of evaporator 70 such that melt water conduit 200 may receive a flow of melt water from evaporator 70 , eg, directly from evaporator 70 The melt water flows without intermediate structures between the evaporator 70 and the melt water conduit 200 . For example, moisture contained in warm moist air 1000 may form frost, eg, by sublimation and/or condensation and then freezing on coils of evaporator 70 (coils are not specifically exemplified herein, but are generally understood by those of ordinary skill in the art). Thus, the refrigeration appliance 100 may include a defrost cycle or operation, and/or the frost may melt over time, thereby generating meltwater. Meltwater may be collected in and/or directed to the meltwater conduit 200 . Auxiliary evaporation pan 202 may be located downstream of meltwater conduit 200, such as immediately downstream of meltwater conduit 202. As a result, the auxiliary evaporation pan 202 receives the meltwater flow from the meltwater conduit 200 , such as directly from the meltwater conduit 200 . As shown in FIG. 7 and described in greater detail below, the refrigeration appliance 100 may also include a primary evaporative pan 302, which may be located downstream of the secondary evaporative pan 202 (relative to the flow of meltwater from the meltwater conduit 200). .

FIG. 4 provides a perspective view of the auxiliary evaporation pan 202 and a portion of the melt water conduit 200 including the downstream end 201 of the melt water conduit 200 ( FIG. 7 ). Figure 5 provides a side view of the auxiliary evaporation pan 202 (the melt water conduit 200 is omitted from Figure 5). FIG. 6 provides a top view of the auxiliary evaporation pan 202 from a plane that intersects the meltwater conduit 200 , such that the meltwater conduit 200 is illustrated in cross-section in FIG. 6 . FIG. 7 provides a partial cross-sectional view of the refrigeration appliance 100 , particularly the lower rear portion of the refrigeration appliance 100 (including the melt water conduit 200 , the auxiliary evaporation pan 202 , and the main evaporation pan 302 ). In particular, FIG. 7 includes a portion of the melt water conduit 200 , a cross-sectional view of the auxiliary evaporation pan 202 , and a portion of the main evaporation pan 302 . As can be seen in FIG. 7 , the primary evaporative pan 302 is disposed vertically below (eg, below along the vertical V) and downstream of the auxiliary evaporative pan 202 within the refrigeration appliance 100 .

In some embodiments, for example, as exemplified in FIGS. 4-7 , the auxiliary evaporation tray 202 may include a water trap 216 . For example, the auxiliary evaporation tray 202 may include a plurality of side walls and bottom walls 212 that collectively define the interior volume 214 of the auxiliary evaporation tray 202 . For example, the plurality of side walls may include a front side wall 206 (eg, facing the front 108 ( FIG. 2 ) of the refrigeration appliance 100 ) and a rear side wall 210 (eg, facing the rear of the refrigeration appliance 100 ) spaced along the transverse direction T 110 (FIG. 7)), and the left side wall 204 and the right side wall 208 spaced along the lateral direction L. Thus, in some embodiments, the side walls 206 , 210 , 204 , and 208 , in combination with the bottom wall 212 , may collectively define the interior volume 214 of the auxiliary evaporation pan 202 . As described below, the interior volume 214 may be open, eg, the auxiliary evaporation pan 202 may omit an upper or top wall in order to facilitate evaporation of the liquid (melt water from the evaporator 70 ) in the auxiliary evaporation pan 202 .

In some embodiments, the water trap 216 may be defined within the interior volume 214 of the auxiliary evaporation pan 202 , eg, between the plurality of side walls 206 , 210 , 204 , and 208 of the auxiliary evaporation pan 202 and between the auxiliary evaporation pan 202 202 above the bottom wall 212. For example, the auxiliary evaporation tray 202 may include a first baffle 218 and a second baffle 220 within the interior volume 214 . Thus, as in the exemplified embodiment, the water trap 216 may be defined by and between the first baffle 218 and the second baffle 220 and two adjacent ones of the plurality of side walls, The two adjacent side walls are such as the right side wall 208 and the rear side wall 210 .

In some embodiments, for example, as exemplified in FIGS. 4 , 6 and 7 , the melt water conduit 200 may extend into the water trap 216 . For example, as best seen in FIG. 7 , meltwater conduit 200 may terminate at downstream end 201 , and downstream end 201 of meltwater conduit 200 may be disposed within water trap 216 . In some embodiments, for example, as exemplified in FIG. 4 , meltwater conduit 200 may include a fitting upstream of water trap 216 , such as elbow fittings exemplified by the exemplary embodiment of FIG. Downstream end 201 ( FIG. 7 ) is aligned with water trap 216 . In other embodiments, the meltwater conduit 200 may omit any such fittings, eg, the meltwater conduit 200 may extend generally in a continuous and uninterrupted line from the evaporator 70 to the auxiliary evaporation pan 202 . Thus, when melt water flows through the melt water conduit 200 and into the auxiliary evaporation pan 202, the melt water first enters the water trap 216, and a predetermined amount of water (eg, reaches the first baffle 218 and/or the second baffle 220) height) is retained within the water trap 216 while the remainder of the meltwater or any additional meltwater flows over the tops of the first baffle 218 and/or the second baffle 220 and into the interior volume of the auxiliary evaporation pan 202 in space 214. The predetermined amount of water retained in the water trap 216 may be partially controlled by the first baffle 218 and/or the second baffle 220 (eg, the lower one in embodiments with unequal heights, or when the heights are equal. is limited by the height of both). 7, the heights of the first baffle 218 and the second baffle 220, or the height of the shorter of the two, may be selected such that the downstream end 201 of the meltwater conduit 200 is lower than the first baffle 218 and The top of the second baffle 220 , and thus the downstream end 201 , can remain submerged in order to reduce or prevent air from entering the melt water conduit 200 .

In particular, each of the plurality of side walls 206 , 210 , 204 and 208 of the auxiliary evaporation tray 202 may define a height along the vertical direction V, and each of the plurality of side walls 206 , 210 , 204 and 208 The height of the side walls may be equal to the height of each other of the plurality of side walls 206 , 210 , 204 and 208 , eg, as can be seen in FIGS. 4 and 7 . In such embodiments, one or both of the first baffle 218 and the second baffle 220 may define a second height along the vertical V, and the second height may be less than the plurality of side walls 206 , 210 , 204 and 208 the height of each sidewall. Thus, melt water can overflow the water trap 216 as described, while also being held within the auxiliary evaporation pan 202 by the plurality of side walls 206 , 210 , 204 and 208 .

When the melt water reaches the interior volume 214 of the auxiliary evaporation tray 202, eg, to the remainder of the interior volume 214 outside the water trap 216, the melt water may be retained in the auxiliary evaporation tray 202 until the melt water reaches the overflow Flow conduit 222 . For example, the overflow conduit 222 may extend generally along the vertical V and may extend through the bottom wall 212 of the auxiliary evaporation pan 202 . In particular, the overflow conduit 222 may extend from an inlet end 224 located within the interior volume 214 of the auxiliary evaporation pan 202, above the bottom wall 212 and below the tops of the plurality of side walls 206, 210, 204 and 208. Extends to an outlet end 226 that is located outside (eg, below) the interior volume 214 of the auxiliary evaporation pan 202 and/or below the bottom wall 212 .

As generally exemplified in FIGS. 4-7 , the auxiliary evaporation tray 202 may include a plurality of legs 228 extending from the bottom wall 212 and/or the side walls 206 , 210 , 204 and 208 of the auxiliary evaporation tray 202 . In the illustrated exemplary embodiment, the auxiliary evaporation tray 202 includes three legs 228 , one extending from the left side wall 204 and two extending from the right side wall 208 . In other embodiments, different numbers and/or locations of legs 228 may be provided, eg, four legs 228 or more, or two legs 228 on the left side and one leg 228 on the right side, and so on. As illustrated, in some embodiments, the legs 228 extend generally in the vertical direction V such that the auxiliary evaporation tray 202 may be spaced from the main evaporation tray 302, such as above the main evaporation tray 302. In some embodiments, the auxiliary evaporation tray 202 may be disposed within the main evaporation tray 302 , for example, the lowermost ends of the legs 228 may be received in the main evaporation tray 302 such that the auxiliary evaporation tray 202 is partially disposed within the main evaporation tray 302 And part is disposed above the main evaporation tray 302 . Thus, the melt water can flow from the auxiliary evaporation pan 202 to the main evaporation pan 302 under the action of gravity.

For example, melt water may flow from the auxiliary pan 202 to the primary evaporation pan 302 via the overflow conduit 222 . As can be seen, for example, in Figures 5 and 7, when the melt water within the interior volume 214 reaches the level at and/or above the inlet end 224 of the overflow conduit 222, the melt water will flow into the overflow conduit 222, It then flows by gravity to the outlet end 226 of the overflow conduit 222 and from the outlet end 226 of the overflow conduit 222 to the main evaporation pan 302 (FIG. 7).

As will be understood by those of ordinary skill in the art, the interior volume 214 of the evaporation pan 202 may be opened at the top of the auxiliary evaporation pan 202 to allow liquid (eg, melt water) stored or maintained in the interior volume 214 to communicate with auxiliary Contact between the air above and around the evaporation pan 202 to facilitate evaporation of liquid (eg, melt water). For example, as seen in FIGS. 6 and 7 , in some embodiments, refrigeration appliance 100 may include evaporative fan 300 that pushes air around and over secondary evaporative pan 202 and primary evaporative pan 302 , to further facilitate the evaporation of melt water from the evaporation trays 202 and 302 .

In some embodiments, the plurality of sidewalls 206 , 210 , 204 and 208 may include sloped sidewalls oriented at a sloped angle relative to vertical V and/or lateral T, for example. For example, as can be seen in FIGS. 4 and 7 , the rear sidewall 210 may be oriented at an oblique angle to the vertical V. FIG. In these embodiments, the rear sidewall 210 may extend rearward and downward. Thus, when the auxiliary evaporative pan 202 is installed within the refrigeration appliance 100 as exemplified in FIG. 7 , the sloping side walls (eg, the rear side wall 210 ) may direct or divert airflow from the evaporative fan 300 to the main evaporative pan 302 and maintain the meltwater in it.
