Abstract
An ice making assembly for use in a refrigerator has an ice forming chamber positioned in the freezer. The chamber has a water reservoir for receiving water, at least one air inlet passage and an outlet opening for permitting cool air flow to pass through the ice forming chamber and over the water reservoir to chill the water into ice pieces. The chamber has an ice displacing device for displacing the ice pieces from the water reservoir and moving the ice pieces out of the ice forming chamber through the outlet opening into an ice storage bin. The bin has a discharge opening for discharging ice pieces from the ice making assembly. The ice making assembly has a downwardly extending baffle positioned across outlet opening of the ice forming chamber. The baffle is slanted from the vertical back towards the outlet opening of the ice making chamber by an angle of about 5.degree. to partially close the outlet opening and to redirect a portion of the air flow normally exiting the outlet opening back into the ice forming chamber and over the water reservoir. The baffle advantageously redirects air flow back over the water to be chilled thereby increasing the heat exchange between the air flow and water without increasing the energy requirements to effect this heat exchange. The improved heat transfer quickens the freezing of the water into ice pieces or cubes.

ICE MAKING ASSEMBLY FOR REFRIGERATOR
Technical Field of the Invention The present invention relates to an ice making assembly for use in a refrigerator, and in particul~~r relates to the use of a baffle positioned in the air flow cooling stream to improve the ice making s process.
Background of the Invention In the modern domestic refrigerators it is common to provide an ice making assembly in the freezer compartment of the refrigerator.
The ice making assembly includes a water reservoir into which water io is supplied. The water is then chilled to form ice pieces. The ice pieces or cubes, are then moved to a storage bin where they are held until the user accesses ice from the refrigerators through an ice dispenser typically mounted through the door of the refrigerator.
When a user obtains ice through the ice dispenser in the door of is the refrigerator, a button is usually pressed which controls the delivery of the ice from the storage bin to tile user. Also, this action controls the making of ice in the ice making assembly. When a user requires substantial amounts of ice from the refrigerators, the ice storage bin

The ice pieces or cubes, are then moved to a storage bin where they are held until the user accesses ice from the refrigerators through an ice dispenser typically mounted through the door of the refrigerator.
When a user obtains ice through the ice dispenser in the door of is the refrigerator, a button is usually pressed which controls the delivery of the ice from the storage bin to tile user. Also, this action controls the making of ice in the ice making assembly. When a user requires substantial amounts of ice from the refrigerators, the ice storage bin
-2- CWC- 167 may not hold sufficient amounts of ice to meet the demands of the user. Accordingly, the user has to wait for the ice making device to make more ice. The time required t:o make ice is a dependent upon the temperature of water being filled into the ice making reservoir and of s the temperature of the cooling air passing over the ice in the of the water reservoir. Currently, it may take as long as 3 hours for the ice maker to form ice pieces for delivery to a user.
Currently, in many ice making assembly, air flow is through the ice making machine above the water reservoir. Consequently, the heat io exchange between the air flow and water is limited to the passage of air over the water because the air passes directly out of the ice forming chamber. In this type of ice making assembly, there is a need to improve the cooling or freezing efficiency of the ice maker without increasing the energy consumed by it the ice maker.
is SUMMARY OF THE INVENTION
In order to improve the efficiency of the ice making process within an ice making assembly, the present invention incorporates the use of an air flow deflection baffle located within the ice making assembly. The air flow baffle is positioned across an outlet opening in Zo the ice forming chamber. The baffle acts to redirect air normally passing out of the outlet opening back into the ice forming chamber and over the water seated in the water reservoir so as to increase the heat exchange between the water being chilled and the coolant air flow within the ice forming chamber. The use of the this air flow baffle Zs results in increasing the speed at which the ice pieces are formed without requiring additional energy. In particular, where the ice

A rear wall passage 29 extends behind the ice making chamber 36 down the refrigerator cabinet to the location of the of evaporator housing and evaporator coils where the as air in the refrigerator it is normally cooled.
Coolant air as shown by arrow 46 enters the ice forming chamber 36 through the air inlet passages 42. The coolant air 46
-6- CWC- 167 passes over the water 40 in the forth ice pieces 48. The coolant air 46 then passes out of the ice forming chamber 36 through a outlet opening 44.
The ice forming chamber 36 has an ice displacing device SO for s displacing the ice pieces 48 from the water reservoir 38. The ice displacing device 50 moves the ice pieces 48 out of the ice forming chamber 36 through the outlet opening 44. The ice to displacing device 50 comprises a series of finger like baffles 51 which are rotatable about axis 53. As the baffle 51 is rotated it forces the ice io pieces 48 out of the water reservoir 38 through the opening 44 and into an ice storage bin 52.
The ice storage bin 52 is positioned in the freezer compartment 14 forward of an adjacent to the ice forming chamber 36. The ice storage bin 52 has a first end 54 in air flow communication with the is outlet opening 44 of the ice forming chambers 36. This permits cool air flow from circulating out of the ice forming chamber 36 and into the storage bin 52 so as to maintain ice pieces 48 located in the storage bin 52 frozen. The ice storage bin 52 has a discharge opening 58 located at the second end 60 oppasite to the first end 54. The ice Zo storage bin 52 further includes a transport device 62 which is in the form of a rotating coil which has a spiral shape to move the ice particles 48 from the first end 54 to the second end 60 and out the discharge opening 58.
The ice making assembly further includes an air deflection 2s baffle 70 positioned across the ice forming chamber 36 at the outlet opening 44. The baffle 70 extends downwardly from the top wall 32 of the freezer compartment 14. The; baffle is L-shaped and has a first

The ice making assembly further includes an air deflection 2s baffle 70 positioned across the ice forming chamber 36 at the outlet opening 44. The baffle 70 extends downwardly from the top wall 32 of the freezer compartment 14. The; baffle is L-shaped and has a first
-7- CWC- 167 leg 72 of the L adapted to be mounted to the freezer liner wall 32. The second leg L of the baffle is a relatively flat portion 74 that extends downwardly into and across the outlet opening 44 of the ice forming chamber 36. The baffle flat leg 74 is slanted forward towards the ice s forming chambers 36 by an angle cx of approximately 5 degrees from the vertical. The second baffle leg 74 is a relatively flat sided surface that faces the outlet opening 44. The baffle partially closes the outlet opening 44 and acts to redirect a portion of the air flow 46 within the ice forming chamber 36 back into the ice forming chamber 36 and io across the water 40 contained in reservoir 38. This redirection of the air flow 46 by the baffle 70 increases the heat exchange between the air flow 46 and the water 40 without increasing the energy requirements of the refrigerator to improve this heat exchange function. The improved heat change quickens the freezing of the is water 40 into ice pieces or ice cubes 48.
