Description

The present invention relates to a cooling counter, in particular for the continuous cooling of bottles, cans and the like by means of cold air supply to the goods outlet, which comprises a multi-level arrangement of support shelves for the bottles, cans, etc.; and where on each support shelf there is 360° access in the horizontal plane to the bottles, cans, etc., which cooling counter is built on an elongated, central, upright support structure comprising an inner column and a concentric tube surrounding this, and where the concentric tube is designed with at least one inlet opening for each floor support shelf, for the supply of cold air to the area above said support shelves.

Such cooling counters are known in various designs.

From NO ulegnningsskrift no. 178 510, a cooling counter of the type indicated at the outset is known, where the cooling counter is built on a central, upright, top-closed cold air supply pipe which is surrounded by a concentric mantle. Under the lower edge of the mantle, the bottle outlet is defined. The bottle outlet extends 360° around a vertical axis which coincides with the longitudinal axis of said central tube. Above the withdrawal point, this is assigned a warehouse for the bottles, cans or containers, delimited between the central pipe and the concentric mantle, where bottles etc. are located, and from which the bottles etc. will slide down into said withdrawal point as bottles etc. are removed from withdrawal point.

This known refrigerator has the advantage that the bottles etc. in its outlet are accessible from all sides, that is 3 60° around the central, upright cold air supply pipe. The jacket concentric with the tube is assigned an upper, coaxial cap which is vertically movable to make said storage available for filling with bottles, cans or other containers.

A significant disadvantage of this known refrigerator is its limited capacity, as it is completely unsuitable for a multi-level design.

Multi-level cooling counters are in and of themselves known in several designs.

One traditional multi-level design of refrigerated counters, which is constructively and functionally built up with a view to ensuring continuous cooling of drinks in bottles and cans, is represented by cabinet-like refrigerated counters with a typical front with a glass door and horizontal shelves at the rear; so-called cabinet coolers. Bottles and/or cans containing drinks are on the shelves in an upright position, presented for sale.

A significant disadvantage of these multi-storey cabinet-like refrigerated counters with fixed shelves is, among other things, that they are only accessible from one of a total of four sides, i.e. over 90°, i.e. the fourth part of the initially mentioned refrigerated counter whose bottle outlet extends over 360° in the horizontal plane. Another disadvantage is that the assortment of bottles and cans easily becomes unmanageable in such a cabinet, where the bottles and cans at the front cover the ones at the back. Customers will often help themselves to one of the front bottles, i.e. normally the bottle inserted last. The operator is tasked with moving cold bottles etc. from the back to the front on the shelves and not satisfactorily cooled bottles from the front to the rear area of the cabinet and shelves.

Another cooling counter is covered by NO patent application no. 953211 (not published). This cooling counter is likewise a multi-level cabinet-like cooling counter, whose bottle outlet points (pull-out drawers) have a limited extent in the direction of the cabinet's circumference.

The refrigerator according to NO patent application no. 953211 has pull-out specially designed drawers that ensure appropriate cold air circulation. Each drawer comprises two joinable parts, an upper separate part, on which the bottles etc. rest, and which forms the outlet, and a lower separate part with an intermediate air supply and extraction chamber. With the help of a pressure fan, the cold air is brought to flow in at the back, at the center of the lower drawer part which is delimited by longitudinal partitions, and is carried forward to the front edge area of the drawer where the upper drawer part is provided with rearward-directed perforation rings, so that the cold air is blown backwards over bottles, cans etc. lying presented for sale on top of the forward-sloping upper drawer part. The upper drawer part has perforations at the back through which the used cold air, which has absorbed heat from the bottles, escapes and is sucked via rear, vertical used air ducts assigned to a suction fan back to the cooling disk's cooling unit.

This fridge has a large capacity, and the individual drawers can contain many bottles and/or cans, as it can easily be designed with five or more drawers in height.

A refrigerated counter designed in accordance with the introductory section is known from SE No. 387234. The purpose of this known refrigerated counter has been that the goods on horizontal shelves on several floors should be accessible from all sides, i.e. 360° around a vertical axis of symmetry. This known refrigerator comprises a rotatably arranged trunk with shelf plates. The trunk includes an open, spherical "cage" around the shelf plates. The cage is formed by 4-8 circular ring-shaped tubes that serve as return channels for used air back to the cooling unit. However, the location of the pipes in relation to the shelves inevitably means that they will limit access to the goods on the shelves, and that the top and bottom shelves will have to be designed with a smaller radial extent than the intermediate shelves. This is obviously disadvantageous with this known refrigerator.

The purpose of the present invention has primarily been to provide a free-standing cooling counter with a large capacity, where the shortcomings and disadvantages pointed out above have been avoided or reduced to a significant extent.

The purpose is achieved with the help of a cooling counter which is distinguished by the characteristic features which appear in the characterizing part of patent claim 1.

With the cooling counter according to the present invention, one does not have to use the spherical, access-restricting cage according to the Swedish specification no. 387234, because used, somewhat heated cooling air according to the invention is transported in the central column's longitudinal bore(s)/channel(s).

According to the invention, the concentric pipe is designed with at least one outlet opening for each floor's support shelf, for the removal of used cooling air to be replaced by new cold air, the outlet openings communicating via connecting pipes with a forced flow of used air in longitudinal bore(s) or channel(s) in the pillar.

A multi-stage cold counter where each floor's bottle outlet has 360° access in the horizontal plane is, according to the present invention, built on a central air-conducting, hollow column known per se, which per se can be assembled from joined coaxial pipe sections. The hollow column is enclosed by a concentric tube which can likewise be built up of joined shorter tube sections, each of which can be composed of, for example, four 90° circumferential parts with two axial limiting edges (which are vertical in the position of use) and two oppositely directed, quarter-circle arc-shaped end edges.

In a first embodiment, the central hollow column is closed at the bottom, under which a pressure fan is arranged which sucks in air from the surroundings via slits in the side wall of the bottom area of the cooling disk and brings the air to cool in the cooling disk's cooling unit, before it is placed in upward flow. As mentioned, the hollow column is closed at the bottom in this embodiment and provided with radial inflow nozzles which correspond to inflow holes (for radial flow from outside/inwards) formed in said outer, concentric tubes, which inflow holes communicate with the upper bottle receiving chamber of each withdrawal point which is equipped with a double bottom, and receives used cooling air from the bottle outlet and transfers this to the central column's vertical cavity, via the hollow column's aforementioned radial pipe connections. The upper open end of the hollow column is assigned to a suction fan, which is arranged in a central bore in an upper hood, and which initiates a forced axially directed flow of used cooling air away from the cooling disk. In the central hollow column with the radially aligned pipe ends, only this unidirectional flow of used air from below/upwards takes place in this embodiment. Said outer concentric pipes also have outflow holes for cold air in a lower part of each outlet point delimiting one floor, as the outflow holes in the outer concentric pipe constitute inflow holes in the lower chamber on the respective floor, that is in the space between the lower bottom of the outlet point (belonging to said lower part) and middle bottom (belonging to the aforementioned upper part). Cold air that enters the space delimited between the two parts of the outlet flows radially forward to the radially inwardly directed holes in the upper part and out of these, for cooling bottles, cans etc. which are located on said intermediate floor. At the 360° surrounding outer edge of each floor/outlet point, the upper part is designed with radial

inwardly directed cold air supply holes for the supply of flowing cold air that flows in between the bottles etc. and passes in heat-changing contact against the side surfaces.

A main embodiment of the cooling counter according to the invention is distinguished by a central, elongated, upright, column-shaped hollow body which exhibits several parallel, mutually separated air flow channels, where at least one channel leads fresh cold air to the respective floor bottle outlet points, while at least one other, from the first separate channel leads used cooling air, where the first-mentioned channel(s) is assigned to a lower pressure fan, while the used air channel(s) is assigned to an upper suction fan, which ensures the blowing out of the used air that has cooled bottles, cans or similar containers during its passage in the respective withdrawal points. The outlet on the respective floor is, in this main embodiment, in principle the same as for the first-mentioned embodiment, but can be made up of two or more segments that each make up a quarter of each outlet, and said lower part has vertical radial boundary walls which form 90° to each other, and which are designed to be able to be connected together with adjacent segments. These limiting walls replace the aforementioned partitions in the previous embodiment. Each outlet segment carries at the radially inner end edges of the boundary walls a quarter, i.e. 90°, of an outer tube section which concentrically surrounds the central columnar hollow body, and which exhibits a lower hole for the supply of fresh cold air under the intermediate floor, which fresh cold air - as in the first embodiment - flows out of radially inwardly directed holes and flows in between bottles, cans etc. and cools these, and an upper hole for outflow of used cold air from the upper part of the outlet, where the middle bottom forms a support shelf for bottles . Spent air is received by at least one corresponding channel in the column-like hollow body from each four-part outlet segment and blown out at the top of the central column-like hollow body.

Both main embodiments exhibit advantageous individual parts and components for the rational manufacture of the respective cooling counter. At each floor's bottle take-out point, said intermediate base, which is carried by the upper part of the bottle support shelf, has a downwardly sloping support shelf part in the direction outwards in the radial direction, which downwards sloping shelf part of the intermediate base transitions into an upwardly sloping shelf part in the direction outwards in the radial direction. The downward-facing shelf section ensures that bottles, cans, etc. slide on the inclined surface radially outwards towards the most common take-out point for bottles, cans, etc., namely the radially outermost part of the support shell (intermediate bottom), which slopes upwards in a radially outward direction and thus stops the bottles, cans, etc. sliding movement.

In another main embodiment of the invention, which includes several modified subordinate embodiments, where the central, tubular column is closed at its upper end, and at its lower, open end passes into one or more side-directed branch pipes with a downward-facing open lower end, which (t) branch pipe's upper, open end "closes" the central tubular column's lower end to the surroundings during full internal air communication between said branch pipe and the tubular column. In this group of embodiments, the central, tubular column also serves as a used-air-carrying pipe, but here the used air is transported in the opposite direction to the other main type of designs, namely downwards, partly due to the still cold air's greater weight than the ambient air, partly due to displacement from continuously supplied freshly cooled cold air through the outer, concentric tube. In this version and modified versions, the used air is recycled in a circuit. Such designs are energy-saving, because less energy is required to further cool down cold used air, which will normally have a lower temperature than the ambient air.

In a somewhat modified embodiment, a fan or similar suction/blowing device can be arranged in the transition point between the central, tubular column and the branch pipe(s) emanating from the same, extending radially outwards/downwards, to initiate a forced flow of the used air.

In the case of an alternative embodiment to the latter

is the fan in said transition point looped; instead, the lower end portion of the branch pipe or each branch pipe is assigned to a fan or similar blowing/suction device.

Examples of embodiments of cooling disks designed in accordance with the present invention are explained in more detail below with reference to accompanying drawings, where: Fig. 1-5 illustrate a first embodiment, while Fig. 6-8 show a second embodiment, and where more specifically determined: Fig. 1 shows a perspective view of a composite, five-tier cooling counter according to the first embodiment; Fig. 2 shows a vertical axial section through the cooling disk according to fig. 1; Fig. 3 corresponds to fig. 2, but visualizes with arrows the air flows, that is to say the flow paths for the fresh cold air, the unused cooling air, and the flow paths for used air; Fig. 4 shows the bottle outlet on one floor of the cooling counter in fig. 1 - 3 and a section of a central, column-like hollow body extending over all floors of the cooling counter; Fig. 5 shows a perspective split view of the individual parts that can make up the bottle outlet according to fig. 4; Fig. 6 shows a perspective axial section through a cooling disk according to a second embodiment, and where the flow path for fresh cold air and for used air is indicated for a quarter segment of a bottle outlet through two vertical, mutually separated channels that are designed in the central , column-like element; Fig. 7 is a perspective split view of one outlet's construction of separate components; Fig. 8 shows a perspective view of a quarter segment for building up a bottle outlet according to fig. 7. Fig. 9 corresponds to fig. 2, but shows a further embodiment where the central, tubular column's upper end looks closed, and where, on the basis of this feature and a special design of the lower end part of the column tube, used-air recirculation has been created, without any special additional fan; Fig. 10 corresponds to fig. 3, but shows a modification of the embodiment in fig. 9, where in the lower part of the central, tubular column where this internally transitions into at least one branch pipe that extends radially outwards and downwards, a used air fan is arranged to create and maintain a forced flow in the used air back to kj the beer aggregate; Fig. 11 corresponds to fig. 10, but shows a modification of this which consists in looping the used air fan from the lower end area of the tubular column, and instead of supplying the branch pipe or each branch pipe with a separate fan element.

A cooling counter designed in accordance with fig. 1 - 5 comprise five floors of 360° accessible support shelves 10a - 10e which form storage rooms and outlets for bottles, cans, etc. not shown. The dressing counter has a lower hollow plinth 12 for receiving the cooling unit and in the wall of which continuous slots 14 are designed for suction of air for cooling and slits 14' for exhausting hot air from the cooling unit. In fig. 9 - 11 there are only ventilation slits 14 in a lower chamber of the hollow base 12, sealingly separated from an upper chamber without such slits.

In fig. 1 indicates 16 an upper hood with a central, vertical through hole 18 for exhausting used air. Moreover, vertical, supporting and stiffening partition walls 20 show that in the design example according to fig. 1-5 divides each bottle outlet's support shelf 10a - 10e into four 90° segments. The reference numeral 22 denotes vertically aligned sleeves in the form of pipe sections for the construction of an outer pipe which concentrically surrounds an elongated, upright, central, column-like hollow body, which is not visible in fig. 1, but which corresponds to the vertically through hole 18 in the cap 16.

At the radially outer, upwardly sloping circumferential portion of each bottle support shelf 10a - 10e in each of the floors of the cooling counter, a large number of radially inward facing holes 24 are formed which are placed and distributed at intervals along a horizontal circle, corresponding to the circumference of the support shelf.

Reference is now made to fig. 2 and 3:

It appears that the refrigerator's plinth 12 is divided approximately in the middle of its height by means of a horizontal plate 26 which is tightly and sealingly connected at its circumference to the plinth 12's inner casing surface. The plate 2 6 divides the base 12 into two chambers 28 and 28'. In the lower chamber 28', a compressor 30, an electronics box 32 and a fan housing 34 for a fan not shown are placed. It appears that the elongated, horizontally-lying, continuous slits 14, 14' are present both in the

upper chamber 28 and in the lower chamber 28'.

In the upper chamber 28, the reference number 36 denotes an evaporator and 38 an underlying fan device which is designed to draw in air radially from the surroundings and blow it - after the cooling effect of evaporation has been utilized - vertically upwards axially.

Between the compressor 30 and the evaporator 36, a first pipeline 40 leads through the plate 26 and a second pipeline 42 leads from the evaporator through the plate 26 to the fan housing 34, where the invisible fan is arranged to blow supplied hot air out through the slits 14'.

The refrigerator according to the one in fig. The embodiment shown in 1-5 comprises, as mentioned, a central, elongated, upright, column-like hollow body 44 which is enclosed concentrically by the outer tube 22 which can be seen in part from fig. 1. The outer pipe 22 can be built up of coaxial pipe sections arranged one above the other, see fig. 4.

Each of the cooling counter's bottle support shelves 10a - 10e is divided by the radial partitions 20 into four 90° segments, each of which is assigned at least one lower supply opening 46 for fresh cold air and at least one upper outlet opening 48 for used cooling air. Said lower supply openings 46 are formed in the outer concentric tube 22, while said upper outlet openings 48 are each formed by an opening 48'

in the outer concentric pipe 22 and a corresponding radial through bore in a radially outwardly directed pipe spigot 50 on the central, column-like hole body 44 which is closed at the bottom by a lower end wall 44'.

The central, upright, column-like hollow body 44

has an open end at the top and in the immediate vicinity above this opening is assigned a suction fan 58 which is arranged in the cap 16's vertical hole 18.

The bottle/can support shelf 10a - 10e in each of the five take-out locations, one in each of the floors of the refrigerated counter, is, in addition to the associated pipe section of the outer concentric pipe 22 and the four radially arranged, 90° angular offset distributed partitions 20, in essentially built up of an underlying, bowl-like, unitary part 54 with a central hole 54' with which it can be threaded down onto the upright, column-like hole body 44, see fig. 5, and four overlying segments 56a, 56b, 56c and 56d of an upper bottle support shelf part which, together with the four partition walls 20 and the tube section of the outer concentric tube 22, form one support shelf for one take-out point which delimits one of the five floors of the cooling counter.

When the ten individual parts according to the perspective split diagram

in fig. 5 is assembled, the 360° rotating support shelf shown in fig. 4, but whose internal structure can best be seen from fig. 2 and 3.

The underlying, bowl-shaped hyUedel 54 has a large

set horizontal bottom part, while the overlying shelf part slopes downwards in a radially outward direction, so that bottles, cans or similar containers will try to slide radially outwards, that is towards the natural outlet, at the front (radially outer) part of each upper ring-shaped support shelf part, which, in order to stop the bottles sliding too strongly towards the front part of the take-out point, is designed obliquely upwards in a direction radially outwards.

Between the horizontal bottom of the underlying bowl-shaped support shelf part 54 and the conical, downwardly sloping bottom of the overlying 90° shelf segments 56a - 56d, which together form an upper shelf part, a cavity 60 appears on each floor which is assigned to the supply of cold air via the outer concentric pipe 22 supply openings 46. Due to the mutual design and form-fitting of the lower and upper shelf parts, the supplied cold air flows to the radially inward outflow openings 24 in the outer peripheral part of the upper shelf parts 56a-56d. Due to the suction fan 58 above the column-like hollow body 44, open at the upper end, which has a closed lower end, a negative pressure is created in the cavity of the upright column 44, whereby used cooling air is drawn radially in through the hollow column 44's radial pipe connections 50, from the outlet where new cold air is supplied.

The air flows can be seen in detail from fig. 3. The peripheral, radially inward outflow openings 24 for cold air are at a higher level on each floor than the outlet openings 48' in the outer concentric tube 22. This difference in height gives rise to a favorable obliquely downward flow of the supplied cold air, into between bottles, boxes or similar that are on the respective support shelf 10a - 10e, presented for sale.

Reference is now made to fig. 6-8 which show a second embodiment which exhibits all the main features of the already described first embodiment according to fig. 1-5.

In the embodiment according to fig. 6 - 8 are parts which are identical or functionally equivalent to corresponding parts in the embodiment according to fig. 1-5 denoted with the same reference designations, and with the addition of a capital letter A for parts with a certain constructive deviation. Thus, the cooling disk according to fig. 6 - 8 likewise five main outlets formed by support shelves 10a - 10e and arranged floor-wise. Each support shelf 10a - 10e corresponds in the assembled state essentially to the embodiment in fig. 1-5, even if the structure itself differs somewhat. The refrigerator's base 12 is designed with continuous, circular holes 14A which correspond to the elongated, horizontal slits 14, 14' in fig. 1-5. An overlying evaporator 3 6 with an underlying fan device 38 that sucks air in radially and feeds it out axially is arranged in the first, upper chamber 28 in the base 12, while the compressor 30, electronics box 32 and fan housing 34 have the same locations and the same functions as previously. A horizontal plate 2 6 separates the cavity in the base 12 in the upper and

lower chamber 28 and 28' respectively.

Instead of the central, upright, column-like hollow body in fig. 1-5, has the embodiment in fig. 6 - 8 a central upright column 62 with longitudinal channels 63a, 63b, 63c, 63d, 63e, 63f, 63g and 63h, fig. 7, which is delimited between radial, axially extending partitions (without reference numbers).

Every other longitudinal channel, for example 63a, 63c ... is closed at the lower end by means of transverse plates 66A, 66C but is open at the upper end, while the other, intermediate longitudinal channels, for example 63b, 63d, 63h . .. are closed at the upper end by means of transverse plates 68b, 68d, 68h ..., but are open at the lower end.

Each tube section, 22 in fig. 1-5, is in the embodiment according to fig. 6-8 composed of four 90° segments each designed with a lower and an upper hole 4 6A and 48A respectively, corresponding to the holes 46 and 48 in the tube sections forming the outer concentric tube.

In fig. 6, only one such pipe section segment 22A is shown whose inlet hole 46A is located in the lower open channel 63h to direct the flow of cold air in the channel 63h into the space 60 between the lower and upper support shelf parts and thence out through the radially inward outflow holes 24, into among bottles, cans etc. for coating these with cold air for the purpose of cooling, before the used cold air flows out through the outlet opening 48A in the tube section segment 22A into the above-open channel 63f for forced outflow through the cap 16's central, through hole 18 The cap 16 is closed at the bottom with a horizontal lower plate 16<1>. The outflow of used air is initiated by means of the suction fan 58 in the same way as in the first embodiment. Arrows show the upward flow of cold air from the lower end of the channel 63h to the inlet opening 46A, from there radially outwards into the space 60 between the bottom of the lower shelf part and the bottom of the upper shelf part

(middle bottom), and from respective support shelves lOe peripheral openings 24 whose mouths are directed radially inwards, preferably somewhat obliquely downwards towards the outlet opening 48A and from there into the channel 63f.

Fig. 7 and 8 show the more detailed design of the individual ring-shaped bottle support shelves 10a - 10e in Fig. 6.

Each shelf is divided into four 90° segments 56A - 56D. The lower part 54A here carries the radial, vertical partition walls 20A, each of which is provided with an upper edge fold 64, with which the lower part 54A can be hooked to the upper edge part of the adjacent partition wall of another lower part of the respective support shelf. The 90° segment 22A of the pipe section is according to fig. 8 carried by the radial inner edges of the partitions 2OA. The segment 22A has two parallel upright strips 70, the spacing of which corresponds to the thickness of the radial, axially extending walls (without reference numbers) which delimit the longitudinal channels 63a - 63h, and with which the segments 22A and thus the lower shelf part 54A (with the loose upper shelf part lying on top) can be clamped to the central upright column 62 which is designed with the longitudinal channels 63a - 63h.

Each pre-assembled annular bottle support shelf 10a-10e has the same basic shape and functions as the annular shelves 10a-10e of FIG. 1 - 5,

that is, with an underlying space 60 which enables the cold air to be fed from the channels in the central upright column element 62 to the peripheral, radially inwardly directed outflow openings 24.

The four upper annular support shelves 10b - 10e

can in both embodiments at a peripheral underlying part (of lower shelf part 54; 54A) have downwardly directed openings (not shown) through which an insignificant amount of cold air escapes so that the hand in the underlying ring shelf 10a - 10d

who is looking for a chilled bottle, will feel the pleasant currents of the cold air.

Fig. 9-11 show three variants which are covered by another main embodiment. A common feature for these three variants is that the upper end 44" of the central tubular column 44 is closed while the lower end of the same is open and assigned to a special branch pipe device 72,74. These features of the central tubular column 44 which for is otherwise provided with radially projecting pipe stubs 50 which extend through the wall of the column 44 and correspond to holes 48' in the aforementioned outer, concentric pipe 22 for the suction of used cooling air to the hollow column 44.

The lower open end of the central, tubular column 44 is internally in air flow connection with, for example, four branch pipes 72 which close the lower end of the tubular column 44 against the surroundings, and extend radially outwards and then downwards, so that their end opening 74 faces downwards and is located at a certain distance from the cooling counter's main fan 38, which sucks in the recycled used air when it has been cooled again in the cooling counter's cooling unit, as in previous embodiments.

The embodiment according to fig. 10, where the air flow patterns are illustrated with arrows, differs essentially from fig. 9 in that a fan or similar suction/blowing device 76 is arranged in the lower end part of a central, tubular column 44 to ensure the flow of the used air for recycling and creating a closed circuit for air.

The embodiment according to fig. 11 essentially differs from fig. 10 in that the fan 76 has been removed from the lower end area of the central, tubular column 44. In contrast, the radially outward and downwardly directed manifolds 72 are each assigned to a fan 78 in their lower, open end portion 74.
