The present disclosure generally relates to ice dispensers, and more particularly to ice dispensers configured for storing and dispensing ice.
This section includes discussion intended to help understand various aspects of the subject matter presently disclosed below. This discussion should not be interpreted as constituting an admission of prior art.
Ice dispensers are generally known in the art for storing and dispensing ice on demand. The ice dispensers include a holding bin for containing the ice, as an auger or another device to move the ice towards a spout for dispensing upon demand. Certain ice dispensers also include a cold plate within the holding bin. The cold plate is provided in thermal contact with one or more lines containing a beverage (e.g., a carbonated water line). The cold plate is situated within the holding bin such that the ice within the holding bin cools the cold plate, which in turn cools the beverage within the lines.
For certain configurations of ice dispensers, ice is made in an external device and manually poured into the holding bin to be stored until a user requests the ice to be dispensed. These ice dispensers may be positioned in a customer-facing location in a restaurant or convenience store. In other examples, the ice dispensers are located behind a service counter or at the back of the house for employees to use in preparing beverages according to a customer order. While the present disclosure generally refers to ice dispensers not configured to produce the ice itself, the present teachings are also applicable to ice dispensers that do produce the ice in addition to holding and dispensing the ice upon demand.
Additional information regarding ice dispensers can be found in U.S. Pat. No. 6,945,070, which is incorporated by reference herein in its entirety.
This Summary is provided to introduce a selection of concepts that are further described below in the Detailed Description. This Summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.
One aspect of the present disclosure generally relates to an ice dispenser for storing and dispensing ice. The ice dispenser includes a holding bin extending longitudinally between a first side and a second side, transversely between a third side and a fourth side, and vertically between a top to a bottom. A chute is configured to guide the ice from outside the holding bin into the holding bin, where the chute has an upper end and an opposite lower end, and where the upper end of the chute extends longitudinally farther than the first side of the holding bin from the second side of the holding bin. A spout is operatively coupled to the holding bin for dispensing ice from the holding bin.
In certain examples, a cold plate is positioned below the holding bin, the cold plate including one or more lines configured to be cooled via the ice from the holding bin.
In certain examples, the lower end of the chute is positioned so as to be approximately vertically even with the top of the holding bin.
In certain examples, the chute extends between the upper end and the lower end at an angle between 20 and 60 degrees relative to the bottom of the holding bin.
In certain examples, a cover encloses the top of the holding bin, the cover having a lid for selectively opening a portion of the cover to access the holding bin. In further examples, the lid is movable between a closed position in which access to the holding bin is blocked and an open position in which the holding bin is accessible, and wherein the lid is rotated between 45 and 90 degrees from the closed position to the open position. In further examples, the lid is pivotally coupled via a pair of hinge arms that remain parallel to each other as the lid is moved between a closed position in which access to the holding bin is blocked and an open position in which the holding bin is accessible. In further examples, the lid extends between a first end and a second end, wherein the lid is pivotally coupled via a pair of hinge arms that each extend between a first end and a second end, and wherein the first ends of the hinge arms are pivotally coupled proximate the upper end of the chute and the second ends of the hinge arms are pivotally coupled to the lid proximate a midpoint of the lid between the first end and the second end thereof. In further examples, a sensor is configured to determine a level of the ice within the holding bin, wherein the sensor is hidden under the cover and accessible by removal thereof.
In certain examples, a sensor is configured to determine a level of the ice within the holding bin. In further examples, the sensor comprises an ultrasonic sensor and/or a radar sensor. Certain examples further include a controller and a light, the controller being operatively connected to both the sensor and the light, wherein the controller is configured to compare the level of the ice within the holding bin to a threshold level and to control the light based on the comparison of the level to the threshold level so as to indicate when additional ice is needed in the holding bin.
Another aspect according to the present disclosure generally relates to an ice dispenser for storing and dispensing ice. The ice dispenser includes a holding bin configured for storing ice. A spout is operatively coupled to the holding bin for dispensing ice from the holding bin. A sensor is configured to determine a level of the ice within the holding bin. A controller and an indicator are configured to generate an indicator for a user, the controller being operatively coupled to the sensor and the indicator, wherein the controller is configured to compare the level of the ice within the holding bin to a threshold level and to control the indicator based on the comparison of the level to the threshold level so as to indicate when additional ice is needed in the holding bin.
In certain examples, a cold plate is positioned below the holding bin, the cold plate including one or more beverage lines configured to be cooled via the ice from the holding bin. IN further examples, the sensor comprises an ultrasonic sensor.
In certain examples, the indicator comprises a light emitting diode, and wherein the controller is configured to turn on the light when the level of the ice within the holding bin is below the threshold level.
In certain examples, a cover encloses a top of the holding bin, the cover having a lid for selectively opening a portion of the cover to access the holding bin. In further examples, the sensor is hidden under the cover and accessible by removal thereof.
In certain examples, a wireless transmitter is operatively coupled to the controller, wherein the controller is further configured to cause the wireless transmitter to send a signal receivable by an external device when additional ice is needed in the holding bin.
Another aspect according to the present disclosure generally relates to an ice dispenser for storing and dispensing ice. The ice dispenser includes a holding bin extending longitudinally between a first side and a second side, transversely between a third side and a fourth side, and vertically between a top to a bottom. A chute configured to guide the ice from outside the holding bin into the holding bin, wherein the chute has an upper end and an opposite lower end, and wherein the upper end of the chute extends longitudinally farther than the first side of the holding bin from the second side of the holding bin. A cold plate is positioned below the holding bin, the cold plate including a beverage line configured to be cooled via the ice from the holding bin. A spout is operatively coupled to the holding bin for dispensing ice from the holding bin. A cover encloses the top of the holding bin, the cover having a lid for selectively opening a portion of the cover to access the holding bin, wherein the lid is pivotally coupled via a pair of hinge arms that remain parallel to each other as the lid is moved between a closed position in which access to the holding bin is blocked and an open position in which the holding bin is accessible. A sensor is configured to determine a level of the ice within the holding bin, wherein the sensor is hidden under the cover and accessible by removal thereof. The ice dispenser further includes a controller and a light, the controller being operatively connected to both the sensor and the light, wherein the controller is configured to compare the level of the ice within the holding bin to a threshold level and to control the light based on the comparison of the level to the threshold level so as to indicate when additional ice is needed in the holding bin.
It should be recognized that the different aspects described throughout this disclosure may be combined in different manners, including those than expressly disclosed in the provided examples, while still constituting an invention accord to the present disclosure. By way of example, certain ice dispensers may have a chute and not include sensors for determining the level of ice in the holding bin, and vice versa.
Various other features, objects and advantages of the disclosure will be made apparent from the following description taken together with the drawings.
The present disclosure generally relates to ice dispensers. In particular, the present disclosure primarily describes ice dispensers that do not make the ice in which they dispenser, but rather those that are manually filled by operators with ice from a remote ice maker.
Ice 14 from the holding bin 12 is funneled down to a center 20 where it falls down onto a cold plate 22 within a chamber 25 positioned below the holding bin 12. The cold plate 22 is provided in thermal connection with beverage lines such that the ice 14 cools the beverage within the beverage lines, via the cold plate 22, in a conventional manner (e.g., as present in the IDC Pro Dispenser offered by Cornelius, Inc. of Glendale Heights, Illinois). A spout 24 is positioned near the front of the ice dispenser 10. An auger device 26 is operable within the chamber 25 to move the ice 14 upwardly and forwardly to be dispensed out of the spout 24 on demand. As ice 14 melts on the cold plate 22, the water drains through a conduit 28 in a conventional manner.
The present inventors have recognized challenges and limitations with using ice dispensers as presently known in the art. First, since this type of ice dispenser does not make the ice itself, it requires periodic attention for both checking the remaining supply of ice and refilling the ice from an external ice maker as needed. In particular, the operator must manually check on the level 32 of ice 14 within the holding bin 12 to see if additional ice must be added. Failure to check on this level 32 of ice 14 in the holding bin 12 on a frequent enough basis can lead to the holding bin 12 running out of ice 14, which would result in dissatisfied customers and/or delays in the dispensing process. On the other hand, checking this level 32 of ice 14 in the holding bin 12 too often also has disadvantages. Manually checking this level 32 requires time from workers who are often fully occupied with other tasks. Moreover, checking the level 32 of ice 14 typically requires the operator to stand on a stool to be able to remove the lid 16 and look down inside the holding bin 12. Thus, each occasion of manually checking the level 32 of ice 14, only to find that additional ice is not needed, represents wasted time and effort, an increased risk of injury to the operator (e.g., unnecessarily climbing on a stool), and increased wear and tear and risk of damage to the ice dispense 10 from additional openings and closings of the lid 16.
The operator's findings upon manual inspection in the holding bin 12 dictate what happens next. If the operator does find that additional ice is indeed needed for the level 32 to reach or exceed a fill line 30, the operator obtains a bucket or bag full of ice and pours it into the open top 18 of the holding bin 12. If instead no additional ice is needed, the operator will likely manually take note of the time and check again after a short while.
The present inventors have further found that it is challenging to gain access to the open top 18 of the holding bin 12 to fill the ice. For example, the present inventors have identified that it would be beneficial for the operator to be as close to the top 18 of the holding bin 12 as possible, particularly since the bucket or bag of ice can be quite heavy and/or awkward to manage and pour. However, the presence of the spout 24 and the general interface 34 of the ice dispenser 10 limit how closely the operator can get to the top 18 of the holding bin 12. By way of example, the general interface 34 may include many items such as display screens or controls, system electronics, power supplies, control boards, and the like, thereby occupying a substantial volume of space as shown.
By way of example, dimensions of the ice dispenser may be approximately as follows:
A chute 60 is positioned at the top 52 of the holding bin 42 and is configured to guide ice from outside the holding bin 42 (e.g., from a remote ice maker) into the holding bin 42. The chute 60 extends from an upper end 62 to a lower end 64 and has a width that in certain examples is approximately equal to a width of the holding bin 42 in the transverse direction. The chute 60 is angled at an angle 65 relative to horizontal such that ice slides down the chute 60 into the holding bin 42. In certain examples, the angle 65 is between 20 and 60 degrees relative to the bottom of the holding bin.
A front 66 of the chute 60 extends forwardly away from the holding bin 42. In other words, the front 66 of the chute 60 extends farther than the first side 44 of the holding bin 42 from the second side 46 of the holding bin in the longitudinal direction. In the embodiment shown, the chute 60 is comprised of two portions; a first portion 61 that is formed with the holding bin 42, and a second portion 63 that is part of a separate module 65 configured to be coupled to the holding bin 42 (discussed further below). It should be recognized that the present disclosure contemplates other designs for the chute 60 feeding ice into the holding bin 42. It should further be recognized that while the angle 65 is referred to singularly, this may be a compound angle of two or more different angles, which may vary for the first portion 61 and the second portion 63, and/or may transition at other locations of the overall chute 60.
By way of example, dimensions of the ice dispenser may be approximately as follows:
With continued reference to
When the lid 50 is open, access to the holding bin 42 is provided via an opening 68 within the top 52 of the holding bin 42. It should be recognized that the opening 68 is covered by the lid 50 when the lid 50 is closed. When the lid 50 is open, ice 14 can then be added to holding bin 42 via the opening 68 in the top 52 thereof. It should be recognized that the present disclosure contemplates designs having different dimensions and angles, such as a chute 60 that is narrower than the width of the holding bin 42 and angled differently than shown, and/or different mechanisms for opening the lid 50, by way of example.
The lower end 66 of the chute 60 is generally aligned vertically with the opening 68 in the top 52 of the holding bin 42. Therefore, any ice 14 that is poured onto the chute 60 is directed or funneled by the chute 60 down into the holding bin 42 via the opening 68. It should be recognized that because the front 66 of the chute 60 extends forwardly from the front 44 of the holding bin 42 (as well as any encasements, cladding, or the like), the operator does not need to reach as far back as the holding bin 42 to pour the ice 14 into the holding bin 42. As shown in
As discussed above, a cold plate 70 is positioned below the holding bin 42 and is configured to be cooled via the ice 14 sitting thereon. The cold plate 70 may be generally positioned and/or configured in a conventional manner, as well as an agitator system to break up the ice and push it out, and spout for dispensing the ice.
With continued reference to
By way of example, the sensor 72 may be a proximity and/or vision-based sensors comprising one or more ultrasonic sensors, radars, LiDAR devices, cameras, lasers, or other devices individually capable of determining distances or relative positions of objects. Certain types of sensors 72 may work better than others within the holding bin 42, particularly as the lighting conditions are very low. In particular, ultrasonic sensors, radar, lasers, or infrared sensors may be particularly well-suited. By way of example, the present inventors have recognized that ultrasound and radar do not require light, which simplifies the design and also provides that detection is not affected by differing levels of ambient lighting. Likewise, ultrasound and radar do not require lenses and thus avoid the need for periodic cleaning. The ultrasonic or radar sensor can also be completely embedded within the holding bin 42 since the energy can be sent at close range through a plastic surface. In this manner, the sensor 72 can be completely enclosed and protected from the environment. By way of example, the sensor may be an ultrasonic sensor made by Pepperl and Fuchs, such as models UC100-18GS-IUEP-IO-V1 or UC400-F77-EP-IO-V31.
With continued reference to
The height or fill level of the ice 14 may be determined as a highest height detected within the field of view FOV of the sensor 72, an average height of multiple heights detected within the field of view FOV, a minimum height detected by the sensor 72, or other configurations. The sensor 72 may also be positioned so as to particularly detect the fill level in a region of the holding bin 42 that is typically lower, such in the back opposite where the ice is filled via the chute 60.
The sensing distance for the sensor 72 is selected or adjusted for the present use, particularly with technologies of sensors 72 requiring a minimum distance from the sensor 72 and the objects being sensed (e.g., closer than that minimum distance may result in the reflected signal missing the detector of the sensor 72 when returning). In certain cases this minimum distance is approximately 3 inches or 76.2 mm.
The sensor 72 is positioned under the cover 48 at the top 52 of the holding bin 42, and particularly under the stationary portion 51 of the cover 48. This positioning provides that the sensor 72 is shielded from the impact of ice being poured into the holding bin 42 via the chute 60. The position may also be specifically selected so as to prevents an optional ice maker (e.g., positioned on the top 52 of the holding bin 42) from interfering with the sensor 72. The sensor 72 may also be contained within an impact resistant housing 74 for further protection, which may also or alternatively protect the sensor from moisture, water, and/or the like.
With reference to
The lower threshold 78 and an upper threshold 80 may be stored as distances from the sensor 72, which can be compared to the fill level measured for the ice 14 in the holding bin 42. The heights corresponding to the lower threshold 78 and upper threshold 80 may also or alternatively be provided as physical demarcations within the holding bin 42 as shown such that sensor 72 (e.g., an optical sensor) and/or the operator can visually discern these levels while filling the holding bin 42.
If the control system CS100 determines that the fill level 76 is below the lower threshold 78, whereby additional ice is needed in the holding bin 42, an indication is provided to the operator via an indicator such as a light emitting diode (LED) 82. By way of example, alternative indicators include a display screen, speaker 83, or wireless transmitter 85 (e.g., a Wi-Fi antenna). In this manner, the indicators are output devices CS101 of the control system CS100. In certain embodiments, the indication is a level of ice is shown on the display screen (e.g., a user interface), for example as a graphical representation of the holding bin with an ice level indicated at a vertical position corresponding to the actual ice lever determined by the system. By way of example, this may be shown at all times, only when the ice level falls below a certain threshold, or the representation may vary by height level (e.g., the level of ice indication turning orange and then red as different thresholds are crossed as ice is depleted).
In certain embodiments, the indicator deactivates again (e.g., the LED 82 turns off) once the fill level 76 is measured to be above the upper threshold 80. In other embodiments, a separate indicator (e.g., another LED) is illuminated to indicate that the holding bin 42 is full once the fill level 76 reaches the upper threshold 80. The indicator may also or alternatively include wireless communicating the need (or non-need) for additional ice, such as by communicating with a wireless receiver positioned elsewhere or carried by the operator. For example, the control system CS100 sends a text message to the operator (e.g., to an external device 87 such as a smart phone) when additional ice is needed, and/or generates a display on an incoming order display notifying the operator of this need.
Additional information is now provided for the example control system CS100 shown in
In certain examples, the control system CS100 communicates with each of the one or more components of the ice dispenser 40 via a communication link CL, which can be any wired or wireless link. The control module CS100 is capable of receiving information and/or controlling one or more operational characteristics of the ice dispenser 40 and its various sub-systems by sending and receiving control signals via the communication links CL. In one example, the communication link CL is a controller area network (CAN) bus; however, other types of links could be used. It will be recognized that the extent of connections and the communication links CL may in fact be one or more shared connections, or links, among some or all of the components in the ice dispenser 40. Moreover, the communication link CL lines are meant only to demonstrate that the various control elements are capable of communicating with one another, and do not represent actual wiring connections between the various elements, nor do they represent the only paths of communication between the elements. Additionally, the ice dispenser 40 may incorporate various types of communication devices and systems, and thus the illustrated communication links CL may in fact represent various different types of wireless and/or wired data communication systems.
The control system CS100 may be a computing system that includes a processing system CS110, memory system CS120, and input/output (I/O) system CS130 for communicating with other devices, such as input devices CS99 (e.g., sensors 72) and output devices CS101 (e.g., LEDs 82), either of which may also or alternatively be stored in a cloud 1002. The processing system CS110 loads and executes an executable program CS122 from the memory system CS120, accesses data CS124 stored within the memory system CS120, and directs the ice dispenser 40 to operate as described herein and also to perform conventional functions.
The processing system CS110 may be implemented as a single microprocessor or other circuitry, or be distributed across multiple processing devices or sub-systems that cooperate to execute the executable program CS122 from the memory system CS120. Non-limiting examples of the processing system include general purpose central processing units, application specific processors, and logic devices.
The memory system CS120 may comprise any storage media readable by the processing system CS110 and capable of storing the executable program CS122 and/or data CS124. The memory system CS120 may be implemented as a single storage device or be distributed across multiple storage devices or sub-systems that cooperate to store computer readable instructions, data structures, program modules, or other data. The memory system CS120 may include volatile and/or non-volatile systems and may include removable and/or non-removable media implemented in any method or technology for storage of information. The storage media may include non-transitory and/or transitory storage media, including random access memory, read only memory, magnetic discs, optical discs, flash memory, virtual memory, and non-virtual memory, magnetic storage devices, or any other medium which can be used to store information and be accessed by an instruction execution system, for example.
In this manner, the ice dispenser 40 provides for automatically determining the fill level 76 of the ice 14 within the holding bin 42 and automatically notifies the operator when attention is needed. Additionally, by including the chute 60, which as stated above extends forwardly from the holding bin 42, the operator's task of accessing the opening 68 in the top 52 of the holding bin 42 is greatly simplified. The operator no longer needs to reach so far longitudinally rearwardly as this chute 60 provides a forward filling mechanism that automatically funnels the ice rearwardly to the holding bin 42. The present inventors have identified that this chute 60 also allows the cover 48 to extend over a greater portion of the top 52 of the holding bin 42. In examples, this may provide improved temperature differential within the holding bin 42 versus the ambient temperature.
The present inventor have also identified that ice dispensers presently known in the art pose challenges in that the location of the ice bin holder make it very difficult to see if the level of ice is sufficient for the dispenser, especially during peak serving times. Even if the machine has an ice maker the demand could exceed the capacity to make ice and could possibly not have enough to dispense ice in a cup and even starve the cold plate of cooling ice. In this case, the operator is unaware that additional ice may need to be added from an external ice maker to meet this demand.
The present inventors have further identified that ice dispensers presently known in the art often provide uneven distribution of ice on the cold plate. This results in poor cooling for the beverage lines and/or other elements meant to be cooled by having ice on the cold plate.
As best seen in
It should be recognized that the shape, size, and position of the opening 202 within the bottom 54 of the holding bin 42 shown is merely one example. The present disclosure contemplates configurations having greater or fewer deflectors, deflectors having different shapes, relative sizes, and positions, and/or other variations that those expressly shown, or a different number of openings or a different location, size, and/or shape of the opening.
In this manner, the presently disclosed ice dispensers provide for even distribution of ice upon the cold plate to maximize heat transfer with the cold plate.
With continued reference to
The base 264 of the hatch system 250 may be coupled to the top 52 via conventional mechanisms, such as a press fit arrangement, being held in place via gravity, using pins and/or other fasteners (e.g., screws or bolts), adhesives, and/or the like. By way of example, the fasteners may be inserted downwardly through the hatch system 250 to be threaded into the top 52 of the holding bin 42 similar to how a spark plug is threaded into an engine block. Quick removal systems such as slotted arrangements, locking clips, plungers, or pins may also be used for fast and tool-less removal.
With reference to
In other words, the pair of hinge arms 276 allow the lid 50 to move upwardly away from the opening 68 providing access to the holding bin 42 while also moving forwardly and subsequently downwardly in front of the interface 34. This provides that the lid 50 is out of the way when the operator wishes to add ice to the holding bin 42 (via the chute 60). In the example shown, the lid 50 moves approximately 90 degrees between the closed and opened positions. This design also provides that the lid 50 does not need to be completely removed and placed anywhere, avoiding a risk of damage.
In certain examples, one end (the first end 278 or the second end 280) of each of the hinge arms 276 is pivotally coupled proximate the upper end 62 of the chute 60 and the opposite end is pivotally coupled to the lid proximate a midpoint of the lid 50 between the first end 254 and the second end 256 thereof. Other configurations are contemplated, including the hinge arms 276 being pivotally coupled in other positions, pivotally coupled such that the lid 50 opens upwardly and rearwardly, and/or sliding in tracks at the lid 50 and/or holding bin 42 ends. The lid 50 may also pivot without a hinge arm, may slide, and/or may be lifted off for opening.
As discussed above, a sensor 72 is provided for measuring the level of the ice within the holding bin 42. In certain examples, the sensor 72 is coupled to the top 52 of the holding bin 42. Other contemplated locations for coupling the sensor 72 include the side walls of the holding bin 42, the lid 50, or others. The present disclosure also contemplates different mechanisms for coupling the sensor 72 to the top 52 of the holding bin 42. In certain examples, the sensor 72 is coupled to the underside of the top 52 of the holding bin 42 or elsewhere via fasteners such as screws. In other examples, the sensor 72 is coupled to the top 52 from above, being threaded into a threaded opening in the top 52, coupled to the top 52 via fasteners such as screws, or other known techniques. In further examples, such as shown in
The present inventors have advantageously identified that certain types of sensors 72, such as radar and ultrasound, can be positioned so as to read through the top 52 of the holding bin 42. This protects the sensors 72 from contacting the ice or other items within the holding bin 42 and also eliminates the need for cleaning.
