The present invention generally concerns ice and water dispensing units and systems for refrigeration appliances, and, in particular, the invention concerns ice and water dispensing units and systems that employ a single paddle operated by a user for dispensing the ice and water.
Refrigeration appliances, such as household refrigerators for example, often are provided with ice and water dispensing systems and units that include dispensing stations at which ice and water can be accessed by users. The dispensing stations can be located at the exteriors of doors that serve to close off the interiors of the refrigeration appliance compartments. In the case of a side-by-side household refrigerator for example, the ice and water dispensing station typically is located at the exterior of the freezer compartment door. On the other hand, in the case of a bottom-mount household refrigerator, that is, a refrigerator in which the freezer compartment is located beneath the fresh food compartment, the ice and water dispensing station typically is located at the exterior of a door at the fresh food compartment.
A variety of mechanisms and arrangements are known for initiating and executing the dispensing of the ice and water from ice-making and ice-storage systems and water sources, respectively, at the dispensing stations of refrigeration appliances. For example, some ice and water dispensing stations include a cavity in the door of the refrigeration appliance and two actuators are mounted in the cavity. One of the actuators causes ice to be dispensed into a receptacle when the receptacle is pressed against the one actuator and the other of the actuators causes water to be dispensed into the receptacle when the receptacle is pressed against the other actuator. In another example, ice and water selection devices such as electrical push buttons or touch screens, for example, are provided at the dispensing station. The ice selection device can be engaged by a user to initiate the delivery of ice to the dispensing station at which the ice can be dispensed into a receptacle that is placed there; and the water selection device can be engaged by a user to initiate the delivery of water to the dispensing station at which the water can be dispensed into a receptacle that is placed there for that purpose. In even other instances, combinations of actuators and selection devices are employed to cause the dispensing of ice and water at the dispensing station.

In this connection, as is familiar to those having ordinary skill in the art, the ice maker 16 can include a cubed ice storage bin, not shown, that includes an auger that is driven by an electric motor and advances the stored cubed ice in the bin to the discharge point for the icemaker whenever ice is to be delivered to the dispensing station 32. And as also is familiar to those skilled in the art, in the case crushed ice is called for, the cubed ice as it advances to the discharge point for the ice maker can be crushed in an ice crusher not shown. In either case, the cubed ice or crushed ice as it reaches the discharge point for the ice maker 16 will be discharged through the housing opening 18 in the housing 17 into the ice delivery chute 23 and be delivered to and dispensed at the dispensing station 32 whenever the ice door located at the chute opening 19 is open.
The dispensing of water can be accomplished by a water delivery system that can be included in the dispensing system, be operably associated with the refrigeration appliance 10 and the dispensing station 32 and be configured to deliver water from the refrigeration appliance 10 to the dispensing station 32 as controlled by the operation of the dispensing unit 30. The system can include, for example, a conduit 26, a first end of which, not shown, is connected to a source of water through a solenoid valve at the refrigeration appliance 10, for example, and a second end of which is connected to the nozzle 28 which is mounted at the dispensing unit 30 as can be seen in
Turning now to a detailed description of the dispensing unit 30 according to an example of the present invention, reference is first had to
In
Whenever neither water nor ice is to be dispensed at the dispensing station, the actuator 45, including the paddle 38, occupies a first or neutral position, sometimes referred to herein as the “non-dispensing position.” In this first position, the actuator 45 and the paddle 38 neither support the delivery of water by the water delivery system nor the delivery of ice by the ice delivery system from the refrigeration appliance 10 to the dispensing station 32 nor the dispensing of water or ice at the dispensing station. However, the actuator 45 can be rotated in the bracket 42 by the advancement of the paddle 38 in the direction of the arrow of
The actuator 45 also includes a passageway, indicated generally at 48 and defined by the ice chute 46, through which ice can be selectively delivered by the ice delivery system from the refrigeration appliance 10 through the ice delivery chute 23 to the dispensing station 32 and dispensed through the ice chute 46 of the actuator at the dispensing station 32 whenever an ice door 50 that includes the seating surface 40 assumes a position away from the bottom of the ice delivery chute 23, thereby opening the passageway 48 to the dispensing of ice. In
The advancement of the paddle 38 towards the rear of the recess 22 and the concomitant rotation of the actuator 45 at the bracket 42 can be accomplished by a user inserting a receptacle such as a drinking glass into the recess 22, engaging the paddle 38 by pushing the drinking glass against the paddle and advancing the paddle in the recess 22 from the first position to the second position for example. Similarly, the rotation of the actuator 45 from the first position through the second position to the third position supporting the dispensing of ice at the dispensing station 32 is carried out by the user inserting the drinking glass into the recess 22 and pushing the drinking glass against the paddle 38 so as to advance the paddle from the first position through the second position further towards the rear of the recess 22 to the third position.
In the embodiment shown in
The example of the dispensing unit 30 illustrated in the figures also can include, as shown in
As indicated above, the placement of the actuator 45 in the second or water-dispensing position supports the delivery of water from the refrigeration appliance 10 to and the dispensing of the water at the dispensing station 32, and the placement of the actuator 45 in the third or ice-dispensing position supports the delivery of ice from the refrigeration appliance 10 to and the dispensing of the ice at the dispensing station 32. However, the actual delivery of water and ice to and the dispensing of water and ice at the dispensing station in the example of the figures, in addition to requiring that the actuator 45 be in the second position for the delivery and dispensing of water and in the third position for the delivery and dispensing of ice, requires that an appropriate one on the water dispensing selector 35, cubed ice dispensing selector 36 and crushed ice dispensing selector 37 be activated. The water dispensing selector 35 is provided for selecting water to be delivered from the refrigeration appliance 10 to the dispensing station 32 and dispensed at the dispensing station when the actuator 45 is in the water-dispensing position and the water dispensing selector has been activated. Thus, the water dispensing selector 35 is operably associated with the water delivery system and is selectively operable upon activation to place the water delivery system in a water-delivery mode. The placement of the water delivery system in the water-delivery mode by the water dispensing selector 35, together with the placement of the actuator 45 in the water-dispensing position, results in the delivery of water by the water delivery system from the refrigeration appliance 10 to the dispensing station 32 and the dispensing of the water at the dispensing station.
With respect to the delivery and dispensing of ice, one of the ice dispensing selectors, either the cubed ice dispensing selector 36 for cubed ice or the crushed ice dispensing selector 37 for crushed ice, is provided for selecting ice to be delivered from the refrigeration appliance 10 to the dispensing station 32 and dispensed at the dispensing station when the actuator 45 is in the ice-dispensing position and one of the ice dispensing selectors has been activated. Thus, the cubed ice dispensing selector 36 and the crushed ice dispensing selector 37 are operably associated with the ice delivery system and are selectively operable upon activation to place the ice delivery system in an ice-delivery mode. The placement of the ice delivery system in the ice-delivery mode by either the cubed ice dispensing selector 36 or the crushed ice dispensing selector 37, together with the placement of the actuator 45 in the ice-dispensing position, results in the delivery of ice by the ice delivery system from the refrigeration appliance 10 to the dispensing station 32 and the dispensing of ice at the dispensing station.
In order to provide for the selective dispensing of water and ice at the dispensing station 32 of the refrigeration appliance 10, a controller 90, referred to in
With respect to the relationship of the controller 90 with the water and ice delivery systems, the controller can be configured to control the placement of the water delivery system in the water-delivery mode and the selective delivery of water by the water delivery system from the refrigeration appliance to the dispensing station as well as to control the dispensing of water at the dispensing station, in response to the placement of the actuator 45 in the water-dispensing position. And the controller 90 can be configured to control the placement of the ice delivery system in the ice-delivery mode and the selective delivery of ice by the ice delivery system from the refrigeration appliance to the dispensing station as well as to control the dispensing of ice at the dispensing station, in response to the placement of the actuator in the ice-dispensing position. In addition, the lighting elements 41, of which there is at least one, can be operably associated with the first actuating device 53 and the controller 90 so that the placement of the first actuating device in the second operational state by the placement of the actuator 45 in the water-dispensing position energizes the lighting elements 41.
In the example of the invention in which the first actuating device 53 and the second actuating device 54 are employed, the controller 90 is operably associated with the actuator 45 through the first actuating device and the second actuating device. Thereby, the controller 90 causes water to be delivered from the refrigeration appliance 10 to and dispensed at the dispensing station 32 in response to the placement of the first actuating device 53 in the second operational state and the activation of the water dispensing selector 35, and ice to be delivered from the refrigeration appliance 10 to and dispensed at the dispensing station 32 in response to the placement of the second actuating device 54 in the fourth operational state and the activation of an ice dispensing selector, either cubed ice dispensing selector 36 or crushed ice dispensing selector 37.
Referring now to
For the purpose of mounting the actuator 45 for rotational movement at the bracket 42, the actuator 45 includes a first arm 55 and a second arm 56 that are located and attached at opposite sides of the ice chute 46 of the actuator 45. The first arm 55 is rotatably supported in a first journal 58 and the second arm 56 is rotatably supported in a second journal 59, each of which journals form a part of the bracket 42. Fixed to and extending at right angles from the first arm 55 toward the front of the bracket 42 and the first actuating device 53 and the second actuating device 54 are a first switch arm 61 and a second switch arm 62. The first switch arm 61 is configured to engage the first actuating device 53 and the second switch arm 62 is configured to engage the second actuating device 54. As will be understood by those skilled in the art, the actuating devices comprise switches that are fixedly mounted to the front of the bracket 42, are activated when the actuator 45 reaches the first and second positions, respectively, and are deactivated when the actuator is returned to the first position.
As has been discussed, the first actuating device 53 is engageable by the actuator 45 through the instrumentality of the first switch arm 61. However, when the actuator 45 and the first switch arm 61 are in respective positions corresponding to the first or non-dispensing position as shown in
When the actuator 45 and the second switch arm 62 are either in respective positions corresponding to the first or non-dispensing position as shown in
The second operational state of the first actuating device 53 and the fourth operational state of the second actuating device 54 comprise operational states in which the actuating devices deliver input signals to the controller 90. The first operational state of the first actuating device 53 and the third operational state of the second actuating device 54 comprise operational states in which the actuating devices do not deliver input signals to the controller 90.
The rotation of the actuator 45 about an axis of rotation that extends through the first arm 55 and the second arm 56 of the actuator 45 is imparted to the actuator, as indicated above, by means of the paddle 38 that is integral with the ice chute 46 of the actuator 45 and forms a downwardly depending and forwardly projecting part of the actuator so as to extend into the recess 22 of the dispensing station 32. As the paddle 38 is advanced towards the rear of the recess 22, away from the front of the recess in the direction of the arrow that appears in
It can be seen in the example of
As noted, in the example of
The advancement of the paddle 38 from the non-dispensing position at the front of the recess 22 towards the rear of the recess takes place against the resistance of a coiled tension spring 64 that is attached to the second arm 56. A free end 65 of the coiled tension spring 64 extends away from the second arm 56 and is configured to engage an abutment at the bracket 42 when the second arm 56 rotates as the paddle 38 is advanced towards the back of the recess 22, causing the coiled tension spring to be wound on the second arm 56. And when the force applied to the paddle 38 for the purpose of advancing the paddle 38 rearwardly in the recess 22, such as would be applied when a receptacle is forced against the paddle 38, is released, the coiled tension spring 64 will unwind, causing the second arm 56 to rotate in a direction counter to the direction in which the second arm rotated upon advancement of the receptacle towards the rear of the recess 22. As a result, the actuator 45, including the paddle 38 will return to the non-dispensing position. As this occurs, the first switch arm 61 and the second switch arm 62, having activated the first actuating device 53 and the second actuating device 54, respectively, for the purpose of supporting the delivery of water and ice from the refrigeration appliance to the dispensing station, assuming that the paddle 38 has been advanced all the way to the ice-dispensing position, will return to the respective positions they assume when the paddle 38 is located in the non-dispensing position. During this return of the first switch arm 61 and the second switch arm 62, the switch arms will cause the first actuating device 53 and the second actuating device 54, respectively, to deactivate so as to place the first actuating device 53 in the first operational state and the second actuating device 54 in the third operational state.
As shown in
Also mounted at the bracket 42 for rotation in the bracket are a mounting rod 72 and a gear rod 74. A first toothed wheel 75 is located at a first end of the gear rod 74 and a second toothed wheel 76 is located at a second end of the gear rod. The first end of the gear rod 74 is journaled to the bracket 42 for rotation at the bracket while the second end of gear rod 74 passes through an opening in the bracket 42 and is journaled for rotation at a friction damper 80 that is mounted at the bracket 42. The mounting rod 72, as shown in
Each of
Referring to
Based on the foregoing description, it will be understood to one skilled in the art that in one embodiment, the ice door 50 includes at least one slot 86 including a slot first side 87 and a slot second side 88; and the actuator 45 includes a respective actuating member 70 located within the at least one slot at the first side of the at least one slot when the actuator is in the first position, at the second side of the at least one slot when the actuator is in the second position and in engagement with the second side of the at least one slot as the actuator moves from the second position to the third position, thereby causing the ice door 50 to open the passageway to the dispensing of ice. And as described, the second side of the at least one slot can comprise a curved surface. Thus, when the actuator 45 rotates from a position at the first side of the slot, as shown in
The inward swinging of the ice door 50 in relation to the actuator 45, thereby opening the passageway 48 to the dispensing of ice, occurs against the stored energy of the elongated coiled tension spring 51 that is fixed to the mounting rod 72. Thus, the ice door 50 will begin to swing inwardly of the ice chute 46 of the actuator 45, as a result of the downward movement of the actuating members 70, 70 in the slots 86, 86 against respective curved surfaces at the slot second sides 88, 88. At the same time, and the mounting rod 72, to which the elongated coiled tension spring 51 is attached, will rotate in the bracket 42 and the U-shaped central portion 52 of the elongated coiled tension spring 51 will engage the underside of the bracket overhang 81, thereby resisting the inward movement of the ice door 50 in the ice chute 46. The continued rotation of the actuator 45, influenced by the rearward advancement of the paddle 38 in the recess 22, will overcome the resistance of the elongated coiled tension spring 51 and the ice door 50 will finally swing to the position shown in
At such time as the pressure against the paddle 38 is released, such as would be the case when a receptacle forced against the paddle is removed, so that the elongated coiled tension spring 51 is allowed to unwind and the force on the elongated coiled tension spring is also released, the depending end portions 60, 60 of the elongated coiled tension spring 51, which lie beneath the ice door 50, will push the ice door to a position once again at which the seating surface 40 of the ice door is seated against the bottom of the ice delivery chute 23 at the chute opening 19, thereby closing off the passageway 48 to the dispensing of ice. As the ice door 50 swings to the closed position, the arcuate sections of the toothed wheels 84, 84 will mesh and rotate with a respective one of the first toothed wheel 75 and the second toothed wheel 76. The force applied by the depending end portions 60, 60 of the elongated coiled tension spring 51 will be resisted by the rotation of the one end of the gear rod 74 that is operatively associated with the friction damper 80 so that the ice door rather than slamming back to a position against the bottom of the ice delivery chute 23 will return to that position in a measured manner.
From the foregoing descriptions and disclosures, it will be understood by those having ordinary skill in the art that the present invention in one of its aspects provides for a dispensing unit 30 that includes an actuator 45 mounted at the dispensing station 32 for selective movement from a first non-dispensing position to a second water-dispensing position, the second position supporting the delivery of water by the water delivery system from the refrigeration appliance 10 to the dispensing station 32. The actuator 45 also is mounted for selective movement from the first position through the second position to a third ice-dispensing position, the third position supporting the delivery of ice by the ice delivery system from the refrigeration appliance 10 to the dispensing station 32. A first actuating device 53 is engageable by the actuator 45 for activation by the placement of the actuator in the second position and is operably associated with the water delivery system for placing the water delivery system in a mode to support the delivery of water by the water delivery system from the refrigeration appliance 10 to the dispensing station 32 upon activation of the first actuating device 53. A second actuating device 54 is engageable by the actuator 45 for activation by the placement of the actuator in the third position and is operably associated with the ice delivery system for placing the ice delivery system in a mode to support the delivery of ice by the ice delivery system from the refrigeration appliance 10 to the dispensing station 32 upon activation of the second actuating device 54.
In the embodiment described above, the seating surface 40 of the ice door 50 is shown to be ellipsoidal in outline with an elongated narrower portion of the seating surface being located adjacent the bracket overhang 81 above a broader portion of the seating surface. At the same time, the perimeter of the opening at the bottom of the ice delivery chute 23 against which the seating surface 40 of the ice door 50 seats can be circular. Because of the ellipsoidal outline of the seating surface 40, in the event the seating surface 40 is misaligned with the opening at the bottom of the ice delivery chute 23, the elongated nature of the seating surface 40 prevents an edge of the seating surface from entering that opening. Otherwise the entry of an edge of the seating surface into the opening at the bottom of the ice delivery chute 23 could prevent the ice door 50 from completely seating against the bottom of the ice delivery chute 23, thereby potentially providing an opening through which ice particles can fall into the dispensing station 32.
As noted above, the functioning of the dispensing unit 30 at the dispensing station 32 and the dispensing system according to the various aspects, embodiments and examples that have been described can be facilitated by the application of a controller that can comprise, for example, a microprocessor. As shown in the example of
On the other hand, for example, if the user, rather than having activated the water dispensing selector 35, has activated either the cubed ice dispensing selector 36 or the crushed ice dispensing selector 37, upon the paddle 38 being advanced to the water-dispensing position, the controller 90 will cause the one or more lighting elements 41 to be energized but the controller will not cause water to be delivered to and dispensed at the dispensing station 32. However, further advancement of the paddle 38 in the recess 22 to the ice-dispensing position will cause the second switch arm 62 to activate the second actuating device 54, resulting in an input signal to the controller 90 which in response to that input signal will cause the ice delivery system to deliver either cubed or crushed ice from the ice maker 16 of the refrigeration appliance 10 to the dispensing station 32, depending on whether the user has activated the cubed ice dispensing selector 36 or the crushed ice dispensing selector 37. And the advancement of the ice in the ice storage bin associated with the ice maker 16 to the discharge point of the ice maker for delivery to the dispensing unit 30 can be accomplished by the controller 90 activating the electric motor that drives the auger that advances the ice in the ice storage bin. In the case in which the crushed ice dispensing selector 37 has been activated, the auger can first advance the ice in the ice storage bin to an ice crusher from which the crushed ice is advanced to the discharge point for delivery to the dispensing unit 30.
Thus, based on the foregoing description, it will be understood by one skilled in the art that the controller 90 can be operably associated with the actuator 45, the first actuating device 53, the second actuating device 54, the water delivery system, the ice delivery system, the water dispensing selector 35, the cubed ice dispensing selector 36 and the crushed ice dispensing selector 37. The controller can be configured to control the delivery of water by the water delivery system from the source of water at the refrigeration appliance 10 to the dispensing station 32 and the dispensing of water at the dispensing station 32, in response to the activation of the water dispensing selector 35 and the placement of the actuator 45 in the second or water-dispensing position. The controller also can be configured to control the delivery of ice by the ice delivery system from the ice maker 16 at the refrigeration appliance 10 to the dispensing station 32 and the dispensing of ice at the dispensing station 32, in response to the activation of either the cubed ice dispensing selector 36 or the crushed ice dispensing selector 37 and the placement of the actuator 45 in the third or ice-dispensing position.
In addition to the dispensing circumstances described in the preceding paragraph, if the user has activated both the water dispensing selector 35 and one of the cubed ice dispensing selector 36 or the crushed ice dispensing selector 37, upon the paddle 38 being advanced in the recess 22 to the water-dispensing position, the controller 90 will cause one or more lighting elements 41 to be energized and water dispensed at the dispensing station 32. Further advancement of the paddle 38 to the ice-dispensing position in the recess 22 will result in the controller 90 causing ice to be dispensed into the receptacle that has already received water. In all these instances, the release of the paddle 38 by the user will allow the paddle to return to the non-dispensing position and, in doing so, the first actuating device 53 and the second actuating device 54 will be deactivated by the first switch arm 61 and the second switch arm 62, respectively, as those switch arms return to the positions they normally assume when the paddle 38 is in the non-dispensing position.
The flapper supporting member 106 includes two interior legs 109, 109, each of which includes an extremity 110 that extends down over a collar 112 of the flapper 102 and two exterior legs 114, 114. Each of the two exterior legs 114, 114 includes an exterior leg intermediate section 115 that extends down over the collar 112 of the flapper 102 and is joined to a slotting bracket, indicated generally at 116. Each slotting bracket defines the slot 86 that includes the slot first side 87 and the slot second side 88 that has a curved surface. Each slot receives a respective actuating member 70 of the actuator 45. The two interior legs 109, 109 at their ends that are opposite their extremities 110, 110 and the two exterior legs 114, 114 at their ends that are opposite the slotting brackets 116, 116 are attached to an annulus 118 that comprises the socket of the ball and socket joint. A ball 119 that is attached to the flapper is retained within the annulus 118.
Integral with and located at the top of each slotting brackets is a respective one of the arcuate toothed wheels 84, 84 that engages and drives a respective one of the first toothed wheel 75 and the second toothed wheel 76 of the gear rod 74, not shown in
According to a further embodiment of the dispensing unit 30, as generally illustrated in
In the same manner as described above with reference to the mechanical embodiment illustrated in
In the embodiment shown in
As shown in
The actuator 45 is mounted for rotational movement at the bracket 42, as described above, by means of the first arm 55 and the second arm 56 that are located and attached at opposite sides of the chute 46 of the actuator 45. Fixed to and extending at a right angle from the first arm 55 toward the front of the bracket 42 and the water and ice actuating device 122 is the switch arm 121. The switch arm 121 is configured to engage the water and ice actuating device 122. The water and ice actuating device 122 can comprise a switch that is configured to function in a first operational state not supporting the dispensing of water or ice at the dispensing station 32 when the actuator 45 is in the first position and to function in a second operational state supporting the selective dispensing of water and ice at the dispensing station 32 when the actuator 45 is in the second position.
For the purpose of opening the modified two-piece ice door 150 in order to dispense ice at the dispensing unit 30, the ice door operator 120 is provided. The ice door operator is configured to cause the modified two-piece ice door 150 to move away from the bottom of the ice delivery chute 23 at which the ice door closes off the delivery of ice to the passageway 48 and open the passageway to the dispensing of ice whenever the actuator 45 is in the second position, and ice has been selected at either the cubed ice dispensing selector 36 or the crushed ice dispensing selector 37 to be dispensed at the dispensing station 32. The ice door operator 120 also is configured to avoid causing the modified two-piece ice door 150 to open the passageway 48 to the dispensing of ice whenever the actuator is in the first position and whenever the actuator is in the second position and ice has not been selected to be dispensed at the dispensing station 32.
The ice door operator 120 can comprise a DC motor that includes an internal gearing arrangement, the details of which are not shown but are familiar to those skilled in the art, including a gear in the nature of a pinion that drives a curved rack 124. An actuating peg 126 is attached to the curved rack 124 and rotates with the rotation of the curved rack for the purpose of opening the modified two-piece ice door 150 as described below.
The modified two-piece ice door 150, as best seen in
The modified flapper supporting member 152 includes two interior legs 109, 109, each of which includes an extremity 110 that extends down over a collar 112 of the flapper 102 and two modified exterior legs 154, 154. Each of the two modified exterior legs 154, 154 includes a modified exterior leg intermediate section 156 that extends down over the collar 112 of the flapper 102 and is integral with a respective exterior leg mounting bracket 158 that is fixedly attached to an ice door positioning member 160 that can comprise a discontinuous rod for example. The two interior legs 109, 109 at their ends that are opposite their extremities and the two modified exterior legs 154, 154 at their ends that are opposite the exterior leg mounting brackets 158, 158 are attached to an annulus 118 that comprises the socket of the universal adjusting member 108. A ball 119 that is attached to the flapper 102 is retained within the annulus 118. A restraining member 162 also is attached to the flapper and is located between the two interior legs 109, 109 where they attach to the annulus 118 for the purpose of retaining the modified flapper supporting member 152 substantially in place and not allowing the modified flapper supporting member 152 to rotate at the flapper 102 and impart a twisting force to the ice door positioning member 160.
As can be seen in
Referring to
The actuating end portion 168 of the ice door positioning member 160 also includes an element 170 in the nature of a camming structure. The element 170 is operatively associated with a safety switch 172. The element 170 is arranged on the actuating end portion 168 in a manner such that when the ice door operator 120 is activated and the ice door positioning member 160 begins to rotate for the purpose of opening the modified two-piece ice door 150, the element 170 will rotate to a position activating the safety switch 172. Upon activation of the safety switch 172, the safety switch will deliver an electrical input signal to a controller described below that, in turn, will activate the auger motor for advancing ice from the ice bin of the ice maker 16 to the opening 18. This prevents ice from exiting the ice bin without the ice door being open which would create a backup of ice in the ice delivery chute 23. In addition, the auger motor also powers the crusher blades for crushing ice. If an individual should thrust his or her hand up through the opening 66 in the actuator 45, the element 170 will rotate to a position activating the switch 172, thereby providing an input to the controller that will result in the ice dispensing sequence being disabled. And that disablement will continue notwithstanding the subsequent advancement of the paddle 38 to an ice dispensing position and the actuation of an ice dispensing selector. Consequently, the ice crusher blades will not be able to be activated under those circumstances.
In order to provide for the selective dispensing of water and ice at the dispensing station of the refrigeration appliance a controller 250, referenced in

The actuating mechanism 182 is pivotally mounted to the vertically displaceable member 190 at a pivot point 200 and includes a manipulating tab 202 that can be used to rotate the actuating mechanism 182 about the pivot point 200 for the purpose of extending and retracting the nozzle 28. As shown in
The actuating mechanism 182 also includes a positioning spring 204 that engages in one of two depressed positions a holding pin 206 that is fixed in place as shown in
From time to time, it can be necessary or desirable to remove the nozzle 28 from the supporting structure 180 such as for the purpose for example of cleaning or replacing the nozzle. In that case the nozzle 28 is placed in an extended position and the nozzle is rotated so that the retaining pin 186 rotates in the retaining slot in which it is held in the ring 188, thereby releasing the connection between nozzle 28 and the ring 188 so that the nozzle can be removed from the supporting structure 180 as shown in
As best seen in
For the purpose of causing water to be delivered to the nozzle 28 when it is in an inclined attitude as show in
In addition to the lighting system that involves the lighting elements 41, that are activated when the actuator 45 is placed in the second position in the embodiments described above, a supplementary lighting system can be provided that can illuminate the nozzle 28 in a manner indicating the status of an operating condition of a separate component of the refrigeration appliance 10. Thus, as shown in
Also by way of example, it can be desirable to know if one of the fresh food compartment or the freezer compartment has reached an undesirably high temperature as would result in the spoiling of food held in those compartments. In that case, the compartments can include a signaling device for generating an electrical output signal that would cause one of the illuminating devices to light up and illuminate the nozzle 28 in an identifying selected color when an undesirably high temperature has been reached.
As indicated above, the functioning of many of the components and elements described can be facilitated by the use of a controller or microprocessor, and this aspect of the invention is illustrated in
