Definitions

  • the invention relates to a method and apparatus for presenting products that are cooled below the ambient temperature, e.g. beverage cans, bottles or other products.
  • a Refrigerated Display Cabinet(RDC) is an apparatus for the display of refrigerated foodstuffs, with the purpose of selling these products to the public.
  • RDCs are used in supermarkets, food stores, convenience stores and other places where refrigerated or deep frozen foodstuffs are sold.
  • the products are cooled by means of cold air flowing along the product, where the cold air has a temperature below the desired product temperature.
  • the product may be cooled by means of contact cooling through the shelf or surface on which the product is placed, where this shelf or surface has a lower temperature than the desired product temperature.
  • a combination of air cooling and contact cooling is also possible.
  • the air that cools the products is cooled inside the RDC and discharged into the area where the products are located through an air discharge opening. After the air has passed over the products, it may be collected again through a suction opening, and cooled again inside the RDC.
  • the movement of the air may be produced by natural phenomena (silent cooling) or may be supported by means of fans.
  • the cooling of the air inside the RDC may be performed with a heat exchanger, along the outside of which the air is led and which on the inner side is fed with a refrigerant or a cooling medium, with a temperature lower than that of the air.
  • the refrigerant or cooling medium can be circulated to the heat exchanger from an external cooling machine (in which case the cabinet is a so called remote cabinet) or can be circulated to the heat exchanger from a cooling machine that is integrated into the RDC (a so called integral cabinet).
  • the part of the RDCs where the refrigerated products are located may be visible to the public, either wholly exposed or by means of a glass door or sliding glass pane.
  • glass doors are common for RDCs that hold frozen foods and for RDCs that hold refrigerated drinks. These RDCs or usually called "glass door cabinets”.
  • the control system of RDCs is dedicated to keep the air temperature inside the cabinet at a desired level.
  • a secondary control is available to provide defrost cycles to the heat exchanger coil, as ice is formed on the coil during operation and the ice needs to be removed at regular intervals.
  • the flow of air in the RDC is constant throughout the whole duration of the cooling period, and is not controlled by the amount of products available in the RDC.
  • the airflow in the RDC may be reduced by means of a control system on the basis of air or coil temperature or on the basis of time or on the basis of air or coil temperature and time.
  • RDCs are used for a variety of cooled products, including dairy products, meat products, seafood products, vegetables, ready meals, flowers and drinks, as well as for frozen products such as vegetables, fish, meat, ready meals and ice cream.
  • Beverage cans or crates filled with bottles of beer or other beverages are products sold in food retail stores and other shops. Unlike dairy and meat products, these products do not need to be cooled for preservation purposes and extension of shelve life. Beverage cans or crates filled with bottles of beer or other beverages can be stored, displayed and sold at ambient temperature. Before actual consumption, beer and other beverages are cooled, to improve the drinking experience. Beer and other beverages are cooled in bottles or cans in a household refrigerator or in a cellar or in a cold water basin of some kind, large enough to hold one can or one bottle or larger. Other beverages alternatively are cooled by means of ice cubes, at the time of drinking.
  • ice cubes are produced in a household or commercial refrigerator with freezing compartment, refrigerator - freezer combination, or freezer.
  • retail cooled bottles or cans of beer or other beverages are displayed in glass door refrigerators, called bottle coolers.
  • the bottles or cans are placed standing side - by - side or alternatively lying in rows, stacked on top of each other.
  • beverage cans are not cooled individually, but the whole interior of the bottle cooler, in which the beverage cans are situated, is cooled.
  • Bottle coolers are not intended for the sale of a crate or crates of beer or other beverages, but for the sale of loose cooled bottles of beer or other beverages. Crates are not placed in glass door bottle coolers, as the horizontal access mode does not comply with the access to the bottles in the crates, where access is from above.
  • Prior art RDCs the interior of the cabinet is cooled as a whole, and the airflow in the cabinet is independent of the number of products stored in the cabinet.
  • Prior-art RDCs bottled or canned beer and beverages are not stored and displayed in cocoons or in a crate or in crates.
  • DE20216677 discloses a car ventilation system with a ventilation outlet that comprises a holder for a beverage container.
  • the holder has a circular opening for receiving the beverage container.
  • the holder has a lid that is forced by a spring to close off the circular opening when no beverage container is present, and is pushed aside by the beverage container when it is inserted.
  • FR2875177 discloses an air conditioning system for a motor vehicle, with a similar accessory for storage of water or food containers, located in a door.
  • the accessory contains a fan located below the floor of the holder to create an air flow along the beverage container.
  • One object is to display and cool products like e.g. beverage cans or bottles etc. in an energy efficient way, while they are placed so that the products can readily be taken out of the cooling environment.
  • a device according to claim 1 and a method according to claim 14 are provided.
  • it is detected which holders are empty and/or which holders are not empty, and to direct, e.g. by air flow control means, the flow of cold air only to holders which contain at least one product to be cooled.
  • the need for cold air is variable, viz. adjusted to only the amount of not empty (or not absent) holders.
  • the cold air may flow around or through the (not empty) holders.
  • the apparatus using the inventive cold air distribution is very well suited for retail situations, where the products are on display to the public and easily accessible without barriers between the products and the public. Every time a consumer picks a product out of the RDC, thus emptying the holder in which the product or set of products was placed, that action is detected and in an embodiment the cold air supply is automatically stopped. When the RDC, by the shop staff, is refilled again, that action is detected too and the cold air supply to the cocoon will be restored again.
  • the device is particularly suited for products containing beverages, as the liquid state of beverages facilitates cooling of the entire product when part of the product is inserted in a holder.
  • the device and method are also applicable for dairy products, meat products, ice cream etc.
  • the holder will also be called “cocoon” hereinafter.
  • the use of an air flow which is controlled by the amount of non-empty/non-absent holders increases the performance of the apparatus by reducing the amount of cold air that is spilt to the environment.
  • This reduction of spilt cold air reduces the amount of refrigeration energy needed by the apparatus.
  • This reduction of spilt cold air also reduces the amount of cold introduced by the apparatus into the comfort zone around the apparatus. In this comfort zone public may be present, that experiences discomfort arising from the introduction of cold air into the comfort zone.
  • Sensing/detecting the amount of empty/absent holders may be based on the weight or the physical boundaries of the products.
  • Control of the air flow may be extended to sensing the amount of e.g. crates partly filled with beverages bottles and adapting the cold air output to those partly filled product holders.
  • the extraction of heat from the cold air flow through the apparatus and through the holders or crates may be done by means of an evaporator coil of a refrigerating machine, where the refrigerating machine is integrated in the apparatus or where the refrigerating machine is located outside the apparatus. It is also possible that cold air is supplied to the apparatus from an external source, where the cold air supplied from the external cold air source makes up for the cold air spilt into the comfort zone and other losses of cold from the apparatus and the holders or crates.
  • Detection means arranged to detect which holders are empty/absent and/or which holders are not empty/absent, and the air flow control means may be arranged electronically, electro-mechanically or pure mechanically.
  • the detection means and the air flow control means may preferably be integrated, and may e.g. comprise a mechanical part which protrudes in the area in which the holder or product resides (not empty/not absent holder state) or not resides (empty/absent holder state).
  • Control means e.g. having the shape of an air flap or slide, may be communicatively connected with the detection means, thus providing direct and simple control of the cold air flow to or through the product holder.
  • a flow of cold air is generated by a cold air generator 1, mounted in the bottom chamber 2 of a housing 3.
  • the housing 3 comprises a vertically extending distribution chamber 4, which may be communicatively connected with a number of restricted holders, also called cocoons 5.
  • Each cocoon 5 may be loaded with one - in figure 1 - or a number - in figure 2 - of the products to be cooled.
  • the product may be cans 6 containing soft drink or beverage.
  • the device moreover, comprises detection means which are arranged for detecting - in the embodiment of this figure 1 - the load (viz. empty of occupied by a can 6) of each cocoon, as well as air flow control means which are arranged to restrict the flow of cold air only to cocoons which are loaded with at least one product to be cooled.
  • the device of figure 1 is arranged so that the cold air flows through the cocoons 5 and mainly around the cans 6. Cold air does not flow through those cocoons 5 of which it is detected that they are empty, thus not loaded with a can 6s, due to the fact that those empty cocoons are cut off from the cold air source, distributed by the distribution chamber 4.
  • the detection means comprise a mechanical detection part in the form of a detection shaft 7, including having a flat end and spring-loaded protruding in the cocoon 5 in which the can 6 may or may not reside.
  • the detection shaft 7 is mechanically communicatively connected with mechanical air flow control means, in the form of a disk-shaped valve 8, cooperating with a valve seat 9 which surrounds an aperture 10 in the wall between the distribution chamber 4 and the series of cocoons 5.
  • the spring-loaded detection shaft 7 When no can 6 is inside a cocoon 5, the spring-loaded detection shaft 7 extends inside the cocoon 5, allowing the valve 8 to rest upon the valve seat 9 and thus closing the aperture 10 and preventing the cold air to enter in the empty cocoon 5. When, however, a can 6 is inserted into the cocoon 5, the spring-loaded detection shaft 7 will be pushed backwards, forcing the valve 8 to leave the valve seat 9 and thus opening the aperture 10 and allowing the cold air to enter in the empty cocoon 5. In this way the mechanical air flow control means are arranged to control the air flow per cocoon, viz. to exclusively flow through the loaded cocoons 5 with cold air while excluding the empty cocoons 5.
  • Each cocoon 5 may be provided with apertures 5a in their sides, enabling the cold air to return, e.g. via a common return chamber 5b, surrounding all individual cocoons 5, to the cold air generator 1.
  • the detection means comprise electrical or electronic detection parts extending to the cocoon 5 or the area in which the cocoon 5 or product 6 may reside, and which are electrically or electronically connected with electric or electromechanical air flow control means arranged to control the air flow per cocoon or per area in which the cocoon or product may reside.
  • the detection means comprise electrical or electronic detection parts extending to the cocoon 5 or the area in which the cocoon 5 or product 6 may reside, and which are electrically or electronically connected with electric or electromechanical air flow control means arranged to control the air flow per cocoon or per area in which the cocoon or product may reside.
  • Figure 2 shows another example of a device for cooling products below the ambient temperature by means of a flow of cold air.
  • the rooms of restricted dimensions, called cocoons are formed by crates or boxes 11 loaded with a number, e.g. ten or fifteen of the products to be cooled, e.g. cans 6 or bottles of beer, which can be piled up on a floor 12.
  • a flow of cold air is generated by a cold air generator 1, mounted in the bottom chamber 2 of a housing 3.
  • the housing 3 comprises a vertically extending distribution chamber 4, which may be communicatively connected with a number of cocoons, having the form here of the boxes 11.
  • each box 11 will be sold as a whole, viz. entirely filled with bottles or cans 6, each cocoon, shaped as a box 11 is loaded with a fixed number of the products to be cooled.
  • the device comprises detection means which are arranged for detecting - in the embodiment of this figure 2 - the presence of each cocoon, as well as air flow control means which are arranged to restrict the flow of cold air only to areas which are occupied by a cocoon, in this case a box (which may be entirely or partly - see note - be filled with bottles or cans 6).
  • the device of figure 2 is arranged such that the cold air flows through the boxes and mainly around the cans 6.
  • Each box 11 is connected to the cold air distribution chamber 4 via controllable cold air outlets which may have the same configuration as the previous example, shown in detail in figure 1c .
  • the detection means comprise a mechanical detection part in the form of a detection shaft 7, including having a flat end and spring-loaded protruding in an (open) area 13 which may or may not be occupied by a box 11.
  • the detection shaft 7 is mechanically communicatively connected with mechanical air flow control means, in the form of a disk-shaped valve 8, cooperating with a valve seat 9 which surrounds an aperture 10 in the wall between the distribution chamber 4 and the area 13.
  • mechanical air flow control means in the form of a disk-shaped valve 8 cooperating with a valve seat 9 which surrounds an aperture 10 in the wall between the distribution chamber 4 and the area 13.
  • each box may be provided with apertures 14 in their side walls which match with the locations of the cold air outlet apertures 10 in the distribution chamber 4.
  • the boxes may be provided with matching apertures 15 in their upper and lower sides, enabling the cold air to flow through the entire pile of boxes, towards the floor 12, which comprise sucking apertures 16, enabling the (main part of the) air flow to return to the cold air generator 1.
  • FIGS 3a-b show a cocoon 5(holder) in cross-section, with and without an inserted beverage can 31 respectively.
  • Holder 5 comprises a support structure 30, a sealing ring 34, a slide 38 and a spring 39.
  • Support structure 30 may be a closed wall, for example, with an inlet and outlet 36a,b for flow of cooled air provided in this wall of holder 5.
  • support structure 30 may be more open, in the form of a wall with openings, a wire cage or a set of bars.
  • support structure 30 defines a cylindrical inner space, such as the space that is walled by the wall, wherein the product can be introduced.
  • Slide 38 is located inside support structure 30 and spring 39 is provided between slide 38 and a bottom of holder 5.
  • Protrusions may be provided on the inside of support structure to restrict the range of movement of slide 38. Sealing ring is located along a perimeter of an opening of holder 5 to let in beverage can 31.
  • Wall 30 of holder 5 may be of cylindrical shape, with a circular cross-section perpendicular to the axis of the cylinder, with a diameter that is sufficient to receive beverage can 31.
  • the support structure is attached to a front panel 32 of the cooling device. Beverage can 31 is inserted only partly in holder 5 by pushing back slider 38 against the force of spring 39.
  • Protrusions may be provided on the inside of support structure 30 of holder 5 to prevent a standard size beverage can from being pushed in completely.
  • beverage can size may for example have a height of 116 millimeter and a diameter of 66 millimeter. Protrusions may be located so that a can supporting surface of slide 38 can be pushed in up to a distance from the surface of front panel 32 that is no more than 80 millimeter.
  • sealing ring 34 may be provided in parallel with sealing ring 34 to cooperate with slide 38 to close of holder 5, sealing ring 34 being used only to operate in combination with beverage can 31 or any other product.
  • sealing ring 34 closes off flow of cooled air out of holder 5 through the opening along the side of beverage can 31.
  • a valve 8 and shaft 7 construction as shown in may be used to close off an inlet conduit for flow of cooled air into the holder.
  • the protrusions on support structure 30 of holder 5 are movably mounted loaded by a further spring, so that they flip back when more than a threshold force is exerted when inserting a product. This enables the protrusions to be pushed aside by exerting extra force when a bottle, which sticks our further than a beverages can, is inserted in holder 5.
  • the support structure comprises an adjustable blocking element that may be fixed in the holder at selectable depths from the front of the holder, to limit the depth to which slider 38 can be pushed.
  • the adjustable blocking element may be implemented as a ring or disc for example that can be placed on selectable sets of supports that are provided at a plurality of depths on the support structure.
  • the inside diameter of the ring or disc is so small that it blocks movement of slider 38, whereas the sets of supports by themselves do not block movement.
  • the ring or disc may be locked to the set of supports.
  • a dedicated tool may be provided to take the disc or ring from a set of supports and move it to another set of supports.
  • Such a blocking element may also be used to block movements of products like beverage cans directly, when no slider is used.
  • FIG 4 shows an alternative embodiment of holder 5, wherein a rotating lid 40 is used instead of slide 38 and spring 39.
  • Rotating lid 40 is rotatable around a rotation axle, between a position wherein it abuts against sealing ring 34 and a position wherein it is pushed against the support structure of holder 5, leaving the opening of holder 5 free.
  • a torsion spring (not shown) is provided attached around the rotation axle of rotating lid 40 to force rotating lid 40 against sealing ring 34 when no external force is inserted.
  • the depth of holder 5 may be selected so that a standard size beverage can will partly extend from holder 5 when it has been inserted.
  • valve 8 and shaft 7 construction as shown in may be used to close off an inlet conduit for flow of cooled air into the holder.
  • Figure 5 schematically shows an embodiment wherein the shape of the inside support structure of holder 5 has a plurality of support structure parts 50, 52.
  • Wall parts 50, 52 which are shown in cross-section, each correspond to a respective cylinder for inserting a beverage holder of a respective size.
  • one beverage holder may be inserted at a time.
  • one cylinder may have a diameter of at least 66 millimeter, and a depth of at most 80 millimeter, corresponding to a standard size beverage can, which can only be partly inserted in the cylinder.
  • Another cylinder may have a diameter of at least 65 millimeter, and a depth of at most 200 millimeter, corresponding to a bottle, which can only be partly inserted in the cylinder.
  • the cylinders are provided extending from sealing ring 34 at the opening of holder 5, an angle to each other.
  • the cylinders differ in depth and/or diameter to a differently sized beverage holder.
  • the support structure parts 50, 52 of holder 5 have surfaces with the shape of the cylinders, but left open where the cylinders extend through each other. In this way, holder 5 is made suitable for alternative placement of differently sized beverage holders, in each case with part of the holder extending from the holder.
  • holders have been shown with horizontal orientation, with a vertical opening for inserting and removing beverage cans with a horizontal movement, it should be realized that different orientations are possible. Using orientations with at least a vertical component has the advantage that products rest in the holders with the aid of gravity, but this is not stricly necessary.
  • the holders may be directed vertically, with a horizontal opening, so that beverage cans have to be removed with an upward movement and inserted with downward movement.
  • the axis of the cylindrical shape of the holder may be at an angle of less than forty five degrees with the vertical.
  • different holders in the same device may have mutually different orientations, for removing beverage cans with movements in different directions, while inside the apparatus the space in holders with different orientations is cooled by a common air flow.
  • a plurality of different orientations axes of the cylindrical shape of the inner space of the holder
  • radiating from a single point may be used, for example at regular angular intervals of sixty degrees or less from each other.
  • more or less random different orientations may be used.
  • Figures 6a-c show various cabinets 60, 64, 66 containing holders with automatically closing openings 62 for beverage containers as described. As will be appreciated the use of such holders makes it possible to provide for openings at various orientations relative to each other within easy reach of different users.
  • Figure 6a shows an embodiment where a tower cabinet 60 is used, with two faces with openings 62, the faces being directed at an angle relative to each other.
  • a holder structure is provided inside cabinet 60, so support beverage containers that are inserted partly extending through openings.
  • a vertical cabinet is shown, it should be appreciated that the cabinet may be tilted or even put in a horizontal position, so that all openings 62 lie at the same height. This provides for access from two directions. In its vertical or slightly tilted position the cabinet can easily be placed with its back against standard shop shelves, to allow users to access both articles on the shelves and from the cabinet.
  • free standing towers more than two faces with openings 62 may be provided.
  • Figure 6b schematically shows an embodiment with a cabinet 64 comprising a plurality of cubes with openings 60 in them on different faces of the cubes. Connections (not shown) between the cubes are provided to transport cooled air to and from the interior of the cubes. The cubes are oriented at different orientations. Again it should be clear from this embodiment that the arrangement with an internal support structure and automatically closing openings enables the ability to provide for access to beverage cans from various directions at the same time.
  • Figure 6c shows a cylindrical tower shape cabinet 66 with a row of openings 60.
  • the tower has sufficient diameter, multiple rows with openings in different directions may be used. With a smaller diameter a single opening may be used at each level of the tower. The openings may be directed in different directions at different levels.
  • Such a structure may be used as a building block of a larger structure with commercially appealing appearance.
  • a palm tree may be built for example, with its trunk made up of one or more of such towers.
