ICE DISPENSING SYSTEM OF HOUSEHOLD REFRIGERATOR BACKGROUND OF THE INVENTION The present invention relates to an improved ice dispensing system of a household refrigerator of the general type disclosed in U.S. Pat. No. 3,640,089 which issued to L. L. Frazier on Feb. 8, 1972, U.S. Pat. No. 3,640,088 which issued to D. W. Jacobus et al. on Feb; 8, 1972, and U.S. Pat. No. 3,602,441 which issued to R. J.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, a refrigerator 10 such as a household refrigerator, for example, has a freezing compartment 12, a shelf 16 within the freezing compartment 12, and an automatic ice dispensing system 18. The automatic ice dispensing system 18 comprises an ice mold 20, means 22 for ejecting formed ice pieces 23 from the mold into a receptacle 26, and a rotatable dispensing means 24 positioned within the receptacle 26 for moving ice pieces through the receptacle 26 and discharging said ice pieces from said receptacle 26, as is known in the art.
The receptacle 26 is supported by the shelf 16 and, as shown in FIG. 2, is positioned laterally adjacent and extends along the length ofthe mold 20. The receptacle 26 has a floor 28 having forward and rearward end portions 30, 32. The floor 28 extends downwardly and rearwardly from the forward end portion 30 to said rearward end portion 32 for gravitationally urging ice pieces 23 within the receptacle 26 to the rearward end portion 32 of said receptacle 26.
The rotatable dispensing means 24 is a helical ele' ment having an axis (not shown) such as a helical tube or auger, for example. The rotatable dispensing means 24 has forward and rearward end portions 34, 36 and is removably connected at one end thereof (37) to a power supply 38 for rotating the rotatable dispensing means 24 and moving ice pieces 23 along the receptacle 26 and discharging said pieces therefrom via a housing 40 which can contain, for example. an ice crusher (not shown).
The rotatable dispensing means 24 extends upwardly and forwardly from said rearward end portion 36 to said forward end portion 34. Preferably, the rotatable dispensing means 24 and the receptacle floor 28 are angularly inclined from the horizontal at a common angle preferably in the range of about 5 to about 15 from the horizontal to assure gravitational movement of the ice pieces 23 within the receptacle while maintaining the energy required by dispensing means 24 at a low value.
Referring to FIGS. 2-4, an ice directing element 42 is connected to the mold 20 and extends laterally outwardly and downwardly therefrom. The ice directing element 42 is of curvilinear configuration which changes in configuration along its length for providing an upper surface 44 which slopes generally downwardly and rearwardly along the length (L) of said directing element 42.
FIG. 3 shows a forward portion 46 of the ice directing element 42 which is adjacent a forward end portion 30 of the receptacle 26 in the installed position thereof and FIG. 4 shows a rearward portion 48 of the ice directing element 42 which is adjacent a rearward end portion 32 of the receptacle 26 in the installed position thereof.
In FIG. 3, the slope of the forward portion 46 of the ice directing element 42 can be seen by observing the downward direction of arrow A which lies along a longitudinally extending segment of the directing element 42. As one progresses rearwardly along a longitudinally extending segment of the directing element 42, the rearwardly directed slope, as depicted by arrow A becomes less. Also referring to FIGS. 3 and 4, it can be seen that the lateral cross sectional configuration of directing element 42 becomes more acute in the downward direction progressing rearwardly along the element 42, i.e.. changing from a modified elliptical configuration to a generally circular configuration.
These unique configurations of the directing element I 42 are provided to facilitate gravitationally moving the ice pieces to a location at the rearward end portion 32 of the receptacle 26. It should he understood. however, that the downward and rearward slopes of the ice directing element 42 can be uniform along the length thereof without departing from this invention.
Referring to FIGS. 1 and 2, a cold air supply source 50 such as a compressor and refrigerant system, for example, is associated with the refrigerator l0 and is connected to means 52, such as a duct work system, for directing cold air from the cold air supply source 50 into the freezing compartment 12, separating the cold air into at least first and second, preferably first, second and third cold air streams 54, 56 and S8, and directing said cold air streams 54, 56 and 58 along preselected portions of the mold for cooling the mold 20 and water contained therein to a temperature at which the water will freeze in the mold 20. thereby forming the ice pieces 23.
The cold air stream 54 from means 52 is discharged through opening 60 and is separated by the mold 20 into the first cold air stream 54 which is directed along a first side 62 of the mold 20. the second cold air stream 56 which is directed along a top 66 of the mold 20, and the third cold air stream 58 which is directed along a bottom 70 of the mold 20.
It has been discovered that if the cold air is not separated and directed against and along different portions of the mold 20, the water in the mold will experience super cooling which will increase the time period required to form ice pieces 23. as opposed to the desired operation of decreasing said time period. By so providing a plurality of cold air streams 54. 56 and 58 and directing these air streams as set forth above by placement of the opening 60. relative to the mold 20 and/or providing air deflecting elements 72 associated with the opening 60. the rate at which ice pieces can be formed is significantly increased.
In order to further assure uniform controlled cooling of the ice dispensing system 18 and associated freezing compartments and controlled flow of said first. second and third cold air streams. means such as openings 74 are provided through shelf 16 for communicating the freezing compartments. These openings 74 additionally provide for air circulation between said compartments when the fan (not shown) of the cold air supply source 50 is not actuated.
In the preferred embodiment. the receptacle 26 and the rotational dispensing means 24 are easily detachable from the power supply 38 and removable as a unit from the freezing compartment 12. It therefore becomes necessary to provide means for accurately and easily positioning and securing ice receptacle 26 rotational dispensing means 24 relative to the mold 20.
Referring to FIGS. 1 and 6. at least one procrusion 76 extends upwardly from the shelf 16 and associates with a centering element 78 which is of a modified V configuration. At the seated position of the unit. as shown in FIG. I. the protrusion 76 is seated in the centering element 78 and at that position a latch 80 has engaged in edge portion 82 of the shelf 16. thereby maintaining the receptacle 26 and associated dispensing means 24 at a pre-selected location relative to the mold 20.
The preferred ice dispensing system 18 also has a pivotally movable ice sensing element 84 for sensing the elevation of the ice pieces 23 within the receptacle 26. When the elevation of the ice pieces 23 has risen in the receptacle 26 to a preselected elevation. the sensing element 84. in response to the ice pieces. is pivoted upwardly to a location at which a switch (not shown) is actuated which terminates the delivery of water to the mold and the formation of ice pieces 23. Subsequent discharge of ice pieces 23 from the receptacle in response to demands of individuals using the system thereafter causes the elevation of the ice pieces 23 within the receptacle 26 to be lowered, thereby lowering the ice sensing element 84 which actuates the switch and initiates ice forming and harvesting operations. The ice sensing element 84 and associated switch means are well known in the art.
Referring to FIGS. 2 and 7, the ice sensing element 84 can be ofa configuration such that. at the lowermost elevation of element 84. a forward portion 83 of element 84 (FIG. 2) is in closer proximity to the immediately adjacent portion of the ice directing element 42 than is the rearward portion 85 of element 84 (FIG. 7) relative to its immediately adjacent portion of the ice directing element 42. This configuration of ice sensing element 84 increases the accuracy of sensing the elevation of ice pieces 23 in the receptacle 26 whereas, in the apparatus of the present invention. the receptacle floor 28 is not horizontal.
Referring to FIGS. 1 and 5 of the improved system, a sensing element switch 86 is mounted adjacent the ice sensing element 84. The switch 86 is slidably movable between a first position (seen in FIG. 1) at which a contacting element 88 of the switch 86 is spaced from the ice sensing element 84, thereby permitting the ice sensing element to operate as set forth above, and a second position (see FIG. 2) at which the switch has been moved upwardly. the contacting element 88 has contacted the ice sensing element 84 and pivotally moved it to the elevated position shown by the broken lines. At this second position. the ice sensing element 84 is at a sufficient elevation to actuate its associated switch to terminate ice forming operations. An individual can thereby easily denergize the ice forming apparatus during periods when the receptacle 26 is removed from the freezing compartment 12.
In the method of this invention. ice pieces 23 are discharged from the mold 20 onto the upper surface 44 of the associated ice directing element 42. Owing to the unique configuration of this surface 44, the ice is urged by gravity toward a rearward end portion 32 of the receptacle 26. The floor 28 of the receptacle 26 is also rearwardly sloping for urging the ice pieces by gravity toward the rearward end portion 32.
Upon actuation of the rotational dispensing means 24 for recovering ice pieces from the receptacle 26, as is known in the art. the helical configuration causes the earliest formed ice pieces. which are located at the lower. rearward portion of the receptacle. to move forwardly for delivery. This unique construction therefore provides control for assuring maintaining relatively fresh ice pieces in the receptacle. The separation and direction of the cold air streams to pre-selected locations on the mold increases the ice production rate of the apparatus and the contacting element 78, latch 80, and sensing element switch 86 increases the conveniences and enjoyment of using the system.
While there has been shown and described a number of embodiments of the present invention. it is to be understood that the invention is not limited thereto and it is intended by the appended claims to cover all such modifications falling within the spirit and scope of the invention.
