The present application and the resultant patent relate generally to merchandising coolers and other types of product dispensers and more particularly relate to an indexing cooler with the features of an open front cooler and/or a supercooling cooler but with the increased energy efficiency of a glass door merchandiser.
Generally described, an open front cooler includes an open refrigerated space with a number of chilled products therein within the reach of a consumer. Because of this quick and easy accessibility and proximity to the chilled products therein, open front coolers often spur impulse purchases from consumers who prefer chilled products as compared to those at ambient temperatures. As a result, open front coolers generally provide an increased sales volume over conventional glass door merchandisers and the like of the same size and/or in similar locations and/or with products stored at ambient temperatures.
One drawback with conventional open front coolers, however, is that the coolers may consume several more times energy than a glass door merchandiser of the same size due to the lack of a door or other type of insulated front space. The increase sales volume generally provided by an open front cooler thus may not cover or justify the increased energy cost.
Likewise, supercooling coolers are increasingly popular. Supercooling coolers may cool a beverage below freezing such that ice crystals may form after the container holding the beverage is opened or energy is otherwise imparted to the beverage to initiate nucleation of the ice crystals. In order for such supercooling techniques to work properly, however, all of the beverages within the cooler must remain within a narrow temperature band at all times.
There is thus a desire for an improved open front cooler, a supercooling cooler, or other type of merchandiser. Such coolers may promote impulse purchases with easy accessibility but with the reduced energy costs of a typical glass door merchandiser and the like.
The present application and the resultant patent provide an indexing cooler for a number of products. The indexing cooler may include an outer shell, a number of rotating product zones, and an indexing drive motor. The indexing drive motor rotates one of the rotating product zones into an exposed zone for a first predetermined length of a time.
The present application and the resultant patent further describe a method of providing a product. The method may include the steps of providing a number of the products in each of a number of product zones, indexing a first one of the product zones about an open front or a door of a cooler, indexing the remaining products zones into a refrigerated product chamber, and indexing a second one of the product zones about the open front or a door of the cooler after a predetermined amount of time.
The present application and the resulting patent further provide an indexing cooler for a number of products. The indexing cooler may include an insulated outer shell, a number of indexing wings defining a number of product zones, and an indexing drive motor for rotating the indexing wings. The indexing drive motor rotates one of the product zones into an exposed zone for a predetermined length of a time.
These and other features and improvements of the present application and the resultant patent will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.
Referring now to the drawings, in which like numerals refer to like elements throughout the several views,
The configuration of the typical glass door merchandiser 10 may lead to the development of a number of thermal gradients therein. For example, the front rows of the shelves 35 may be warmer than the back rows due to radiation heat transfer through the glass panel 30 of the door 20, the lights 45, and less insulation. Likewise, the cooling air flow may warm as it rises through the glass door merchandiser 10.
The indexing system 160 may operate in a manner similar to a revolving door. The indexing system 160 thus may include a number of indexing wings 200 that may rotate within the product chamber 170. In this example, three indexing wings 200 are shown, a first indexing wing 210, a second indexing wing 220, and a third indexing wing 230. Any number of the indexing wings 200 may be used herein. The indexing wings 200 may have any suitable size, shape, or configuration. The indexing wings 200 may extend from and may rotate about the air plenum 190 at one end thereof. The indexing wings 200 may have a brush seal 240 and the like at the far end thereof. The brush seals 240 ensure that the cooler air does not escape from the product chamber 170 into the open front 150. Other types of mechanical seals may be used herein. A number of product shelves 245 and the like may be positioned on each of the indexing wings 200. The product shelves 245 may have any suitable size, shape, or configuration. The indexing wings 200 may rotate via an indexing drive motor 255. The indexing drive motor 255 may be any type of conventional drive device. Other components and other configurations may be used herein.
The indexing wings 200 may divide the product chamber 170 into three product zones 250, a first product zone 260, a second product zone 270, and a third product zone 280. Any number of the products zones 250 may be used herein. The product zones 250 may have any suitable size, shape, or configuration. In this example, at any given time, one of the product zones 250 will be an exposed zone 275 adjacent to the open front 150 while the other two product zones 250 will be refrigerated zones 265 in communication with the refrigerated component area 140. As is shown in
In use, any number of the products 110 may be loaded into each of the product shelves 245 in the product zones 250. The indexing system 160 may rotate at any predetermined interval. For example, the indexing system may index one product zone 250 into to the exposed zone 275 by the open front 150 approximately every 30 seconds or so. Any other period of time may be used. Specifically, one of the product zones 250 will be in the exposed zone 275 adjacent to the open front 150 of the outer shell 120 and thus exposed to ambient temperatures. The remaining product zones 250, however, will remain within the refrigerated zones 265 of the product chamber 170 and thus in the refrigerated space. For example, the first product zone 260 may be adjacent to the open front 150 for about 30 seconds or any given amount of time. The products 110 therein thus are easily accessible by consumers in the manner of a typical open front cooler. The second product zone 270 and the third product zone 280, however, remain within the product chamber 170 and hence refrigerated for about 60 seconds such that the ratio of ambient to refrigerated is about 1:2. Other ratios may be used herein. The indexing cooler 100 may have proximity sensors and the like that prevent rotation when a consumer approaches so as to given the consumer a sufficient amount of time to make a selection.
The indexing cooler 100 also may incorporate lighting and/or sound. In other words, the indexing cooler 100 may employ lighting, graphics, sound, and the like when rotating or otherwise. In addition to the impulse purchases often provided by an open front cooler, the motion of the rotating product zones 250 also may serve to attract a consumer's attention.
The indexing cooler 100 thus provides the benefits of a conventional open front cooler with the energy savings generally associated with a closed glass door merchandiser. Moreover, the use of the multiple product zones 250 allows the indexing cooler 100 to provide and promote more types of different brands than is typically possible in a stationary cooler. Other components and other configurations may be used herein.
The supercooling indexing cooler 500 may include the indexing system 160 within the product chamber 170. In this example, the three indexing wings 210, 220, and 230 are shown although any number of the indexing wings 200 may be used herein. The three indexing wings 210, 220, 230 may divide the product chamber 170 into the three product zones 260, 270, 280 although any number of the product zones 250 may be used herein. The indexing wings 210, 220, 230 may use the brush seals 240 and the like. As above, at any given time one of the product zones 250 will be in the exposed area 275 facing the glass door 510 and two of the product zones 250 will be sealed thereof in the refrigerated zones 265. Given the use of the three product zones 250, each product zone 250 will extend for about 120 degrees or about one-third of the total rotation. An amount of insulation 530 may be positioned between the product zones 250 and the outer shell 120.
In order to avoid the thermal gradients Tg described above, either top to bottom or front to back, the indexing system 160 may be timed to rotate at a predetermined interval. Such timed rotation provides equal time for all products 110 to be exposed to the cold air in the refrigerated zone 265 and limits the time about the door 510 in the exposed zone 275. Moreover, consumers may see the different product zones 250 with a multitude of products 110 therein and a multitude of product choices. As is shown in
The supercooling indexing cooler 500 also may accommodate different set points for different types of beverages. The volume and speed of the airflow may have an impact on the formation, or not, of thermal gradients therein.
The various configurations and combinations described herein for the indexing coolers are for the purpose of example only. Many different configurations and combinations of shapes and sizes may be used herein. The supercooling indexing cooler 500 provides supercooling ability with the indexing system 160 further attracting consumer interest, i.e., the motion of the indexing system 160 also serves to attract attention. Specifically, the use of the door 510, the insulation 530, and the predetermined rotation of the indexing system 160 to limit the time in the exposed zone 275 provides the reduced thermal gradients required for supercooling. The indexing system 160 also avoids “dead” spaces in the cooler such as against a back wall, a corner, the lights, and so forth where consumers may avoid selecting a product and hence may lead to waste. Rather, the indexing system 160 promotes easy access with equal product promotion therein.
It should be apparent that the foregoing relates only to certain embodiments of the present application and the resultant patent. Numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
