Description

F reezer insert with forced convection F ield of the invention

The present invention pertai ns to a freezer insert with forced convection, for use in chill ing foods or beverages, for example, as well as an application for a freezer insert with forced convection

Prior art

From US9080807 it is known to have a permanently integrated section for quick cool down i n a refrigerator/freezer, where the cool er i s pi aced i n the refrigerator, from whi ch it takes i n ai r from the freezer, and at the same ti me it vi brates the products, where the products can be up to 2 cans or a bottl e of wi ne. S i nee the cool er i s an i ntegrated part of the ref ri gerator, it always takes up room i n the refrigerator, whi ch I i mits the usabl e space in the refrigerator. The system between freezer and refrigerator also results in a significant pressure drop. From US7343748 it is also known to have a permanently mounted cooler for use in cool i ng down round obj ects i n a refrigerator, where the cool er has a fan and a pi pe wi th hoi es and a rotor f uncti on. T he cool er takes i n ai r di rectly from the refrigerator and has a high pressure drop across the air distribution holes. From US 5207762 furthermore there is known a mobile cooler, which can cool down round obj ects, where the cool er has a housi ng with a fan and a centeri ng unit T he cool er can be placed i n a freezer or a refrigerator and cools down the products with the hel p of the high air speed. The invention pertains to heat conductive flexible elements to hold the item which is being cooled down.

T he cool er i s I i mited to only cool i ng down one obj ect at a ti me and does not i ncl ude a means of hoi di ng devi ce such as an i ntegrated or external handl e.

From WO2014048657 it is known for a freezer containing confectionary for consumer operation, when buying confectionary, which has a fan to ensure optimal ventilation throughout all regi ons of the freezer. T hi s al I ows for a very narrow temperature range which thereby ensures a high quality of the delicate confectionaries. This design has furthermore shown to lower the overall energy consumption for the whole freezer because of the narrow temperature range which makes the regulation of the temperature more eff i ci ent T hi s i nventi on rel ates to gentl e agi tati on of the ai r i n the freezer and does not cover rapid cool down of various products.

Purpose of the invention

The purpose of the invention is to indicate a freezer insert for placement in a freezer, where the freezer insert includes forced convection for use in rapid cooling of foods or beverages, for exampl e, where a high ai r speed around the obj ects ensures a faster cool down than without forced convection. Rapid freezing of foods furthermore ensures a higher quality than slow freezing in a conventional freezer.

L i kewi se, one purpose of the i nventi on i s to i ndi cate a freezer i nsert whi ch can be used for various purposes and not j ust for cool down of beverages, but also for example for cool down of foods and ice, and where the same freezer insert can be adapted to these objects by means of partitions in the freezer insert.

It is furthermore a purpose of the invention to indicate a freezer insert which fills and takes up the least possible space in a refrigerator/freezer, an upright freezer or a chest freezer or i n the home i n general, si nee this freezer i nsert can be used for keepi ng other frozen goods when it is not in use.

Specification of the invention

According to a fi rst aspect of the invention, the above i ndicated purpose is achieved with a freezer insert with forced convection as described in the introduction, and as specified in the preamble of claim 1, where the freezer insert comprises at least one compartment, which is rectangular with a length direction, a top and a bottom, a first end and a second end, a wall with an outside and an inside, and where the first end of the compartment comprises a blower and-or blowers and a power supply connection and where the second end of the compartment is open and where the i nsi de of the wal I comprises at least one spacer where an outflow of air does not occur until the air has passed through the products, thus maximizing air speed. T his makes it possi bl e to connect the bl ower and- or bl owers to an i nternal power supply, for example in the form of a battery, or to connect the blower to an outside power supply, for example in the form of the power supply of the freezer or in the form of the mains supply.

The freezer insert works like a wind tunnel for the objects, where the air circulation is produced by means of axial and/or centrifugal ventilation, and where the air passes underneath, along and around an object Thus, it is a forced convection, where a liquid for example changes its density as a result of cooling.

The spacers furthermore make it possible to maintain a certain distance between a can or cans and the wall of the compartment, so that air can pass underneath, along and around such a can or cans. A spacer can be, for example, in the form of a rib, a projection, a cam or a gui de. T he freezer i nsert i n a preferred embodi ment has several spacers for optimal placement of several products for the best possible air circulation around the products. T he obj ect or obj ects and the compartment are stati onary i n regard to each other duri ng the cool down.

The compartment in one embodiment can be made as a single piece, but it is also pos- si ble for the compartment to consist of several elements, where one element can constitute the door of the chest freezer, for exampl e, and/or a part of the top si de i n an upright freezer or a freezer drawer situated on top.

The invention thus makes possible both rapid cool down of beverages, but also rapid freezing of foods and ice. In the case of ice, ice cubes can thus be made quickly, and also popsicles can be made quickly by rapid freezing.

In a preferred embodi ment, the freezer i nsert comprises at least one compartment which is substantially rectangular in a cross section perpendicular to the length di rection of the compartment.

In another preferred embodi ment the freezer i nsert where at I east one spacer is situated in the length direction of the compartment T his makes it furthermore possi ble to ensure that the ai r can ci rculate around the object or objects, and where the spacers in one embodiment can moreover be made antislip with a high friction coating in the form of, for example, a film li ning or other surface treatment. In a preferred embodiment the spacers will be placed substantial ly in the bottom of the compartment in order to make possible the passage of air, but in other preferred embodi ments the spacers can likewise be placed in other areas of the wall or i n the wi dth di recti on of the compartment so that obj ects cannot come i nto di rect contact with the wall of the compartment at any place in the compartment Thus, with the spacers situated in the length direction of the compartment a more linear concentrated air flow along the walls of the compartment and thus a less turbulent airflow is assured.

In an alternative embodiment the spacers can be placed in such a way in the compartment that i n fact turbul ent ai r f I ows are achi eved, when thi s shoul d prove to be desi rabl e. In an alternative embodi ment one or more mi 11 ed grooves i n the spacers to enabl e round objects to be centered in these milled grooves by placing the objects laying across or standi ng verti cal ly i n the compartment to keep the obj ects mai ntai ned i n positi on when the freezer drawer is pulled back and forth in longitudinal direction, and when the objects are affected by the air pressure from the blower and-or blowers. The location of the milled grooves in the spacers can also indicate the location in the freezer i nsert, with the best ai r ci rculati on and thereby i ndi cate the opti mum area where to place the products. Test have shown that the optimal cool down time is achieved when the products are placed relatively close to the bl ower-and or bl owers i n the freezer i nsert and the opti mum I ocati on for the mi 11 ed grooves wi 11 thereby be i n the spacers i n a short distance from the bl ower-and or blowers.

T he present i nventi on al so i nvol ves i n a second aspect that the freezer i nsert furthermore contains at least one compartment partition situated i n the length direction of the corrv partment where the compartment furthermore comprises holdi ng devices for partiti on- i ng of the compartment and where mounti ng and demounti ng of the compartment partiti ons are done manually by placing it on top of the holding devices.

This makes it possible to partition the compartment into several parts and thus ensure that there can be several objects in the compartment, several objects in a layer, without the obj ects bei ng i n contact with each other, yet ensuri ng an ai r space around the obj ects so that forced convection is possible under all circumstances, regardless of the number of objects and regardless of the number of partitions in the compartment Because the partition of the compartment is situated in the length direction of the compartment, it is assured that the surrounding medium, preferably atmospheric air, can pass through the objects and thus can pass through the compartment

The compartment partitions in a preferred embodiment can likewise contai n spacers. In this way, several objects can be cooled down at the same time and with the spacers, the objects and the at least one wall of the compartment can be held at a fixed distance in relation to each other. T he compartment partition furthermore makes it possible to have both standi ng and ly i ng obj ects i n the freezer i nsert at the same ti me. In a preferred embodi ment, the compartment partiti on is I i kewise provi ded with spacers, so that one can maintain a certain distance between for example a can and the wall of the compartment such that air can pass underneath, along and around such a can. With the compartment partition situated in the compartment s length direction a more linear concentrated ai r f I ow i s thus assured through the compartment and so al so a I ess turbu- lent air flow.

In an alternative embodiment the compartment partition can likewise be placed in such a way in the compartment that a turbulent air flow is obtained, if this should be desired. The holding devices can in a preferred embodiment also be created so that the compart- ment partition closest to the blower and-or blowers can be placed in an angled position. T his wi 11 enabl e the enti re f I ow of ai r from the bl ower and-or bl owers to be di rected to the bottom of the freezer i nsert compartment whi ch thereby wi 11 give the fastest cool i ng ti me i n the event that there are only pi aced obj ects i n the I ower part of the compartment

In a preferred embodiment the side of the compartment partition is uninterrupted and thus preferably in the form of a sheet, but in an alternative embodimentthe sides of the compartment partition can be outfitted with through holes in an arbitrary pattern. The present invention also involves in a third aspect a freezer insert with forced convection, which can be fitted with an extendable compartment partition where a part of the compartment partition has grooves to guide the extendable part of the compartment partition.

This will enable a more compact design which require less detachable parts than with a divided compartment partition.

In a preferred embodiment the compartment partition can be parted i n the middle and thereby f ol ded i nto the wal I on each si de of the compartment i n such a way that no space is obtained when the partition is not in use.

In a preferred embodiment, the compartment partition can be folded by means of hinges or other flexible joint and thereby make the compartment partitions a fixed part of the design thus eli minate the need for removable and loose parts in the design. This makes it possible to hide the foldable compartment partitions in the sides of the compartment and thereby have the enti re vol ume of the compartment avai I abl e for products.

In another embodiment, the compartment partition can be both extendable and foldable for optimal position of the compartment partition always. This wi ll enable a larger range of product to be cooled down due to the combined design of both the foldable and the extendabl e compartment parti ti on.

The present invention also involves in a fourth aspect a freezer insert with forced convection, where the freezer insert furthermore comprises at least one compartment extension, where the freezer insert and the compartment extension have interconnection means.

The compartment extension likewise comprises a compartment partition in the corrv partmenfs I ength direction with spacers. The compartment partition can furthermore be foldable by means of hinges and thereby fold the compartment partition into the side walls.

The compartment partition can be extendable my means of grooves for extension. This makes it possible in a preferred embodi ment to place up to even more cans in the freezer i nsert on which a compartment extension has been mounted, whereas for exampl e it is only possi bl e to place less standard 33 cl . cans without the compartment exten- sion mounted. With the compartment extension, it is possible to combine several objects of the same or different si ze, obj ects with a greater wi dth/l ength than other obj ects, and thus for exampl e i ce cubes i n bags or trays can be cool ed down at the same ti me as meat trays. Likewise, objects can be combined, such as where popsicles are being frozen and wine bottles chilled. However, this means that the cool down procedure wi 11 be interrupted when the wine has been chilled, after which the cool down procedure will con- ti nue unti I the i ce is frozen.

For example, the interconnection means can be a snap lock, a click lock, tongue and groove, or other type of male and female lock which assures a coupling together. T he present invention also i nvolves i n a fifth aspect a freezer i nsert with forced convection, where the compartment comprises at least one removable wall part and a sealing edge along at least parts of the periphery of the removable wall part.

This makes it possible to achieve a freezer insert which is open and easily accessible al ong the enti re compartment but preferably from the top. T he removabl e wal I part can be, for example, a part loosely placed on the wall or an attached wall part.

When placed in a freezer, it is possible to do enti rely without the removable wall part insofar as the wall part is at the top of the freezer insert since the missing part of the compartment can be formed i nstead by a freezer door, gate, or shelf. R egardl ess of how the removable wall part is placed in relation to the compartment a sealing edge along at I east parts of the removabl e wal I part i s a means of creati ng and provi di ng a compartment where an outflow of ai r does not occur until the air has passed through the products, thus mi ni mi z i ng ai r I eakage.

In a preferred embodi ment one si de of the si dewal I can be removabl e with the possi bi I- i ty of changi ng the wi dth of the freezer i nsert compartment whi ch makes it possi bl e for the freezer i nsert to f i 1 1 arger obj ects than wi th the normal wi dth. The present invention also involves in a sixth aspect a freezer insert with forced convection, where the at least one end of the compartment comprises at least one part of a freezer fasteni ng devi ce. This makes i t possi bl e to secure the freezer i nsert at I east temporari ly to a pi acement i n a freezer or in a drawer in a freezer. The freezer i nsert can furthermore be lifted by the fastening device, so that the freezer insert can be transported with all its contents for quick catering. In one embodiment, the freezer insert can be integrated in the freezer, not taking up needless space in the freezer, since it can be used only for keeping of goods when not i n use for rapi d cool down. T he area i s therefore used for general products, and when a rapid cool down is desired the section can be organized opti mally for this by means of compartment partitions, among other things.

The present invention also involves in a seventh aspect a freezer insert with forced convection, where the power supply comprises at least one battery.

This makes it possi ble to operate the blower during the time when the freezer insert is present in the freezer. In a preferred embodiment the battery is rechargeable and in another preferred embodiment the recharging occurs with the help of a USB charger or a USB cable, or another type of charger.

There is a risk of the batteries losing their service life when placed in the freezer, but this can be solved in a preferred embodiment by packing the batteries in insulation or drawing on their own power supply, thereby using some of the battery^'s own energy to keep them warm by means of heat traci ng and thereby assure a I onger servi ce I ife and- or better f uncti on especi al ly duri ng chargi ng i n col d envi ronments. T he heat traci ng can also be powered from an external power supply such as the charger.

In one embodi rnent where the freezer i nsert can be i ntegrated i n the freezer, the battery can be omitted, for example, and the power supply connection of the blower can come, for example, via the freezer s own wiri ng or plug-in in the freezer itself. In a preferred embodiment, a timer function, an alarm function, a control panel, Wi-Fi, Bluetooth is integrated in the design. In an alternative embodiment, the freezer insert could have in pace of Wi-Fi or Bl uetooth communication to a smartphone a different unit for control of the freezer insert s functions.

This makes it possible to control the cool ing time, depending on which products are bei ng cool ed, for exampl e, by havi ng a control panel wi th ti mer and al arm f uncti on. T he freezer insert can alternatively also be provided with acoustic alarm or be able to send signals to telephone via an app for use after the cooli ng ti me is over.

With a control panel, a timer and/or an alarm function it is thus possible to combi ne and control the obj ects more easi ly, for exampl e when popsi cl es are bei ng frozen and wi ne bottles are being chilled. Therefore, this means that the cool i ng procedure will be interrupted when the wi ne has been chilled, which a timer and an alarm can assure, after which the cooling procedure can continue until the popsi cles are frozen. In a preferred embodi ment, the f uncti ons can be control I ed from a panel on the freezer insert; but in the embodiment where the freezer insert can be integrated in the freezer this can alternatively be done from a control panel on the freezer itself, or via the af ore- mentioned signal to an outside unit such as a smartphone. The present i nventi on also involves in an eighth aspect the use of a freezer insert with forced convection for loose placement in a freezer, where the freezer insert can have any shape or form, for use in the cooling of foods or beverages, for example.

In a preferred embodiment the freezer compartment can have external or internal han- dl e for easy transportati on.

By having an integrated handle in the wall, the total outside volume is reduced thus making the freezer insert more compact than havi ng an outside handle. If fitted with an integrated handle the manufacturing cost of the freezer insert can be lowered because material is removed from the wall situated around the compartment and or situated in another location on the freezer i nsert.

This makes it possible to place the freezer i nsert loosely in both a chest freezer and the drawers of an upright freezer and to place the freezer insert where it best fits and by possible dismounting of the compartment extension to adapt the size to the available room. The freezer insert can of course also be placed in a kitchen cupboard or the like, when it is not i n use. The present invention also involves in a ninth aspect the use of a concave air intake situated on the intake side of the blower and or blowers. This will make it possible to position the loose freezer insert in an upright position in the freezer if decided. The intake air will thereby be able to reach the blower through the concave openings even if the freezer insert is positioned facing with the open end upwards and the blower end downwards and-or towards and even surface whi ch coul d have bl ocked the ai r f I ow if a concave design was not used.

The present invention also involves in a tenth aspect the use of a freezer insert with forced convection for direct or indirect fastening in a freezer for use in the cooling of foods or beverages, for exampl e.

This makes possible direct fastening of the freezer insert to means prepared for this in the freezer. Alternatively, this makes possi ble the indirect fastening of the freezer insert to the freezer, for example, fastening the freezer unit to a drawer in the freezer, which coul d be i n the mi ddl e of the freezer drawer or i n one si de of the freezer drawer. T hi s will create a freezer drawer which comprises of two or more compartments with easy access from above.

In a special alternative application, the freezer insert can also be used for warming up of cold products to a higher temperature. For example, this can be done by placing frozen objects in the i nsert and placing the insert in a setting where the temperature is higher than the temperature of the objects, in which case the frozen objects will thaw out even more qui ckly as a result of the passage of the warmer surroundi ng ai r through the frozen objects, i.e., likewise as a result of forced convection. The freezer insert can thus be used both for cool i ng of I i qui ds and meat or f reezi ng of i ce cubes/meat products, and for thawi ng of obj ects when pi aced i n surroundi ngs at room temperature, for exam- pi e. It i s thus possi bl e to use the freezer i nsert for thawi ng of food products and other products, where the freezer insert is used as a fan and where frozen elements are placed in the compartment and where the freezer insert is then placed in warm surroundings. In a special alternative appl ication, the freezer insert can also be used as a cooling fan for the placement of al ready chi 11 ed products, such as chi 11 i ng el ements, i n warmer sur- roundings when it is desired to cool down the surrounding air.

In a special alternative application, the invention can be used for pharmaceutical purposes, for example, for cool down of medicine.
