     DETAILED DESCRIPTION 
       [0021]      FIG. 1  illustrates one embodiment of a refrigerator of the present invention. In  FIG. 1  a refrigerator  10  has a bottom mount freezer with French doors. It is should be understood that the present invention may be used in other configurations including side-by-side refrigerator configurations and other types of configurations. The refrigerator  10  has a refrigerator cabinet  12 . One or more compartments are disposed within the refrigerator cabinet  12 . As shown in  FIG. 1 , a fresh food compartment  14  is shown with French doors  16 ,  18  providing access to the fresh food compartment  14 . Below the fresh food compartment  14  is a freezer compartment  20  which may be accessed by pulling drawer  22  outwardly. 
         [0022]    Mounted on the door  16  is an ice maker  24 . An ice bucket  26  such as a container to hold or store ice is also mounted on the door  16 . As shown in  FIG. 1 , the ice bucket  26  is positioned below the ice maker  24 . Preferably, the ice maker  24  is configured to make clear ice or wet ice which is ice which is generally transparent and generally appears not to have air or other impurities. Such ice is generally made at a temperature near freezing. 
         [0023]    There is a drain  52  in the ice bucket  26 . To maintain the ice as clear ice, or wet ice, ice is stored in the ice bucket  26  temporarily and allowed to melt thereby resulting in melt water. The melt water may be separated from the ice stored in the ice bucket  26  and released. The melt water may then be conveyed from the ice bucket  26  through the drain  52  to another location. Alternatively, the melt water may be collected in the ice bucket  26 . Although various locations are contemplated to drain the melt water, as will be discussed with respect to various embodiments, one such location is an evaporator  32  in the machine compartment  30  of the refrigerator  10 . Alternatively, the melt water may be drained to evaporator trays elsewhere in the refrigerator such as in the fresh food or refrigeration compartment or the melt water may be drained to a reservoir that a user empties, or the melt water may be recycled such as to be re-frozen into cubes, dispensed as drink water, misted, or drained from the refrigerator. 
         [0024]      FIG. 2  illustrates one example of an ice bucket  26  with ice cubes  46  stored therein. The ice bucket  26  may have insulated walls such as insulated upper walls  40 ,  42  forming an integral one piece chamber  44 . A funnel  48  may be used to funnel ice  46  away from the ice bucket to another location such as to a dispenser. A drip edge  50  may be provided. As ice melts in the ice bucket  26  the melt water may be conveyed down edges of a chute  51  and may then be captured in a water trap  52 . The melt water may then be conveyed through a gutter or tube  56  to an evaporator tray  32 . The melt water may then be evaporated at the evaporator tray  32 . The drip edge  50  may be generally above the water trap  52  so that droplets of melt water fall into or above the water trap  52 . 
         [0025]      FIG. 3  illustrates another embodiment. In  FIG. 3 , instead of routing melt water from the ice bucket  26  to an evaporator, melt water is routed to be used for an alternative purpose. For example, the melt water may be routed to a pump  29 . As shown in  FIG. 3 , the melt water may be routed to a mister  31  having a pump  29 . The mister  31  may be positioned within a refrigeration compartment to mist contents within the fresh food or refrigeration compartment. For example, the mister  31  may be used to mist fruits or vegetables. Alternatively, the mister may be used to mist the melt water outside of the refrigerator so as to function as a humidifier. In addition, the pump  29  may be used in alternative configurations where a mister is not used. 
         [0026]      FIG. 4  illustrates another embodiment. In  FIG. 4 , instead of routing melt water from the ice bucket to an evaporator, melt water is routed to the ice maker  24  using a pump  29 . Thus, melt water can be recycled and used to produce additional ice. Where melt water is used in this way, it is noted that the melt water is already at a temperature just above freezing which minimizes the amount of energy needed to cool water in comparison to using water which is at a warmer temperature. 
         [0027]      FIG. 5  illustrates another embodiment. In  FIG. 5 , melt water from the ice bucket  26  is routed to a reservoir  33 . The reservoir may be a user removable reservoir which can be periodically emptied by a user of the refrigerator to remove the collected melt water from the refrigerator. Alternatively, the reservoir may collect water to be used as consumable drink water. 
         [0028]      FIG. 6  illustrates alternative placements of the ice storage bucket which may be used in alternative embodiments. Note that the ice storage bucket may be placed in any number of different locations associated with the refrigerator  10 . This may include placing the ice storage bucket  26 A on a first French door  16  to the refrigeration compartment  14 . Alternatively ice storage bucket  26 B may be placed within the refrigeration or fresh food compartment  14 . Ice storage bucket  26 C is shown on a second French door  18 . Alternatively, the ice storage bucket  26 D may be placed on a drawer  22  of the freezer compartment  20 . In another embodiment, the ice storage bucket  26 E may be placed within the freezer compartment  20 . Thus, it is to be understood that the present invention contemplates that an ice storage bucket may be placed in any number of locations. The particular location of the ice storage bucket may be determined based on the location of the ice maker, the manner in which ice is conveyed from the ice maker to the ice bucket, the location of an ice dispenser, the manner in which ice is conveyed from the ice storage bucket to the ice dispenser if present, the manner in which the ice storage bucket is cooled, and other considerations. Although a French door refrigerator with a bottom mount freezer is shown, it is to be understood that the present invention contemplates that other configurations of refrigerators may be used include side-by-side refrigerators, other configurations with bottom mount freezers, and other configurations with top mount freezers. 
         [0029]      FIG. 7  is a flow chart illustrating one embodiment of a method of the present invention. In step  80  ice is made. Preferably, the ice is made in a process which allows for clear ice or wet ice to be made. In step  82 , the ice is conveyed to the bucket with a drain. In step  84 , the ice is maintained within the bucket at a temperature above freezing. This may be accomplished through natural heat loss or by forcing heat. Examples of force heat methods may include warm air ducted into the above zero temperature compartment, a heater, conduction of heat, a heat pipe and heat loops, a thermoelectric, and a fluid and heat exchanger. The manner in which the ice is maintained within the bucket at a temperature above freezing may depend upon the location of the bucket. For example, if the ice storage bucket is positioned within a refrigeration compartment then natural heat loss may be relied upon. Alternatively, if the ice storage bucket is positioned within a freezer compartment than force heat methods may be used to maintain the ice in the bucket at temperature above freezing. It is further contemplated that natural heat loss may provide for improved energy efficiency. Next, in step  86 , water is drained in the bucket. In step  88 , melt water drained from the bucket may be conveyed to another location which may be remote from the ice bucket. The melt water may be conveyed to an evaporator, a reservoir, a mister, an ice maker, or other location. The melt water may be recycled or repurposed within the refrigerator. Alternatively, the melt water may be removed from the refrigerator such as by conveying the melt water to an outside drain or misting the water outside of the refrigerator into its environment to function as a humidifier, or to water plants/sprouts, or for other purposes. 
         [0030]      FIG. 8  illustrates another embodiment of the ice bucket  26  of the refrigerator. In  FIG. 8 , the drain  52  is within the ice bucket  26 . A gutter or tube  56  may be used to remove melt water and convey the melt water to another location, such as a pump, a reservoir, an evaporator or elsewhere. 
         [0031]      FIG. 9  illustrates another embodiment of the ice bucket  26  of the refrigerator. In  FIG. 9 , one or more drains  52  may be positioned within the ice bucket  26  and corresponding gutters or tubes  56  may be used to convey melt water to reservoirs  33  within the ice bucket. The present invention contemplates that melt water in the reservoir(s)  33  may be temporarily stored and/or may be recycled. 
         [0032]    The invention has been shown and described above, and it is understood that many alternatives modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention. For example, the present invention may be used in various different types of refrigerator configurations, the ice storage bucket may be placed in various locations throughout the refrigerator, the ice bucket and drain may have variations in structure, once drained melt water may be recycled, repurposed, or removed from the refrigerator. These and other variations, options, and alternatives may be used with the present invention.
