Description

The present invention relates to a method for recording the contents of a storage room, in particular a storage room of a refrigerating appliance and means for carrying out the method.

Out EP 1 679 636 A1 is a refrigeration device with a divided into several compartments storage space, an RFID reader and an antenna assembly is known, the antennas are able to communicate with RFID tags that are attached to stored in the storage room Kühlgutstücken. Based on a comparison of signal strengths, a decision is made as to which of the compartments spaced apart from the antenna arrangement is an RFID tag or the piece of refrigerated goods marked with it. For such a comparison to provide accurate results, the structure of the antenna array must be tailored to the arrangement of the bins; for refrigerators with variable compartmentalization, the approach is therefore not suitable, and for different refrigeration appliance models that differ in the geometry of their storage space, a specially adapted antenna array is required in each case.

In order for a user of this known device to be able to see in which of the several compartments a particular piece of refrigerated goods is located, he must be able to inform the appliance to which goods to be refrigerated he wants information. Suggestions as to how this can usefully be done are not made. However, even if the user has succeeded in specifying the desired piece of refrigerated goods, and then he gets specified by the device, the tray in which it is located, the search for him can be time-consuming and cumbersome in a compartment containing many other chilled goods, in particular if, as is often the case in the compartments of freezers, many different refrigerated items are stacked on top of each other.

The object of the present invention is therefore to provide a method which makes it easier for a user to find an object in at least one storage space and can be applied without costly optimization to storage spaces with different geometries.

• a) Bereitstellen eines Satzes von berührungslos ablesbaren Datenträgern, wobei jeder der Datenträger eine für ihn spezifische Information enthält,
• b) körperliches Verbinden eines der Datenträger mit einem Lagergut,
• c) Platzieren des Lagerguts mit dem Datenträger in dem wenigstens einen Lagerraum,
• d) Ablesen des Datenträgers in dem wenigstens einen Lagerraum,
• e) Ableiten wenigstens einer kontinuierlich variablen Ortskoordinate des Datenträgers und
• f) Markieren des der abgeleiteten Ortskoordinate entsprechenden Orts.

The problem is solved by a method with the steps:

• a) providing a set of non-contact readable data carriers, each of the data carriers containing information specific to it,
• b) physically connecting one of the data carriers with a stored product,
• c) placing the stored material with the data carrier in the at least one storage space,
• d) reading the data carrier in the at least one storage room,
• e) deriving at least one continuously variable spatial coordinate of the data carrier and
• f) marking the location corresponding to the derived location coordinate.

Although a storage space which is subdivided into a plurality of discrete compartments, an inaccuracy in deriving the location coordinate or during marking may mean that a user can not unequivocally recognize on which side of the border between two compartments the desired storage material is located allows the continuously variable spatial coordinate with sufficient resolution of the derivative, the area of the storage room, the user must actually search for the stored goods, to limit a fraction of the volume of a compartment.

The marking can take place directly in the storage room by illuminating the location corresponding to the derived location coordinate in the storage room.

In a preferred, more generally applicable embodiment, marking comprises displaying a map of the storage room having a mark at the location corresponding to the derived location coordinate.

If the method is performed exclusively on a refrigerator, a display screen for displaying the card on the refrigerator itself may be provided.

In particular, if the storage space is large enough to be accessed by the user, it is advantageous if the card is output to a mobile data terminal for playback and thus can be consulted by the user while he is in the storage room.

Such a storage space may in particular comprise a complete pantry including any refrigeration device therein, or even more rooms of a building.

As a reading device for reading the data carrier in the storage room, a camera can be used. This is particularly practical if, as is usually the case on a shelf or on the shelves of a refrigerator, the storage items individually and from at least one direction are freely visible and identifiable.

For the more general applicability, it is preferred that at least one radio signal receiver, in particular an RFID transmitter, is used as the reading device for reading the data carrier in the storage space. Receiver, is used because the communication of the transmitter / receiver with a mounted on the storage medium data medium is also possible without direct line of sight. In particular, low-cost RFID tags may be considered as data carriers, but other standards such as Bluetooth may also be used.

Preferably, the location coordinate is derived by means of triangulation with the aid of a plurality of radio signal receivers.

It would also be conceivable to use radio signal receivers with antenna arrays which are capable of transmitting and / or receiving from a specific spatial direction through phase coupling of the individual antennas, and from the respectively set phase shifts between the antennas to the direction close, in which a disk is relative to the antenna.

With the help of a reader arranged in the storage room, the reading of the data carrier in the storage room can also take place without the presence of the consumer. The output of stored stock-specific information can be made at the request of the user, in particular by remote data transmission, if he wants to get to the inventory without buying the storeroom, and to decide on subsequent purchases. The output of the information can also be fully automatic, e.g. to a dealer, if this is to deliver on the basis of this information certain stored goods.

A record that associates the information specific to the volume with information specific to the stored goods associated with the volume is advantageously usable for various purposes.

On the one hand, upon receipt of a user's search for stored goods, it can be decided on the basis of the stock-goods-specific information of the data set whether the stored goods associated with the data carrier correspond to the search query and, consequently, if the location where the latter is located should be marked or not.

On the other hand, an entry can additionally be included in the data record which contains the date of introduction of the stored goods into the storage space or a date derived therefrom. On the basis of such an entry, a search query of the user can be answered immediately to be used storage goods or a recommendation to consume a specific storage goods soon, be given automatically.

If the stored material can be placed in one of several warehouses different in their storage conditions in step c) then it should be expedient to determine in which of these warehouses the stored material is actually located; the derived date should be determined in step j) taking into account the storage conditions become. Thus, e.g. be differentiated in the estimation of the durability of a food, whether it has been housed in one of various areas of a refrigerator such as a refrigerator compartment or a freezer, or even in a storage room outside the refrigerator.

The information specific to the volume merely has to allow the distinction of each volume from all other volumes of the set; a linkage of this information with a specific storage product is made only by connecting the data carrier with the stored goods and the creation of the record. This process can be repeated as often as desired for the same volume. Since a private consumer can make it, also a collection of transfilled or self-produced stored goods is possible.

If the data carrier is attached to a container, in step b) the physical connection may include the filling of the product to be cooled into the container. Since the consumer usually fills his own prepared food in a container before storing it in a refrigerator or transports food from opened, unsafe, resealable sales packaging, this step does not entail any additional workload for the consumer.

If step d) is performed after each closing of the storage space, it can be detected by whether there have been changes in the inventory.

If, for example, among the data carriers read, one for which no stock-specific information is stored in the database, then this must have come into the storage room during the door open. In this case, to create a record of this volume of required stock specific information may be requested by the consumer, i. a request may be made to the consumer to indicate what type of stored product belongs to the data carrier or what is contained in the container provided with the data carrier.

A required for issuing this request or entering the stock-specific information interface can be on the refrigerator or on the Storage room itself be provided. However, the use of a mobile data terminal networked with the reader and the database, such as a tablet PC or a smartphone, may be more cost-effective and more convenient for the consumer.

If, in step d), a data carrier is not found in the storage room to which a data record exists in the database, then it can be concluded that the stored goods provided with the relevant data carrier have been removed. In the simplest case, it can then be assumed that the stored goods have been used up, and the associated data record can be deleted; then the data medium is available again for use for other stored goods. However, if the stored goods were not or not completely used up and are put back in the storage room at a later time, then the data record would have to be recreated at this time. Therefore, preferably, the record of a removed item to be cooled is not immediately deleted but only marked as removed. If then at a later repetition of step d) the disk in question is again found in the storage room, the existing record can be reused, or a request can be issued to the consumer, in which the latter is asked to decide whether the existing record continues apply or create a new one.

A quick and comfortable way to create the dataset is to photograph the stored goods. In particular, if, as mentioned above, the request for warehouse specific information is sent to a mobile terminal, the camera installed in most of these devices may be used.

In order to create the data record of a stored good, it makes sense to read the data carrier-specific information from the storage medium assigned to the storage medium. This can be done as described above by the associated data carrier read by the reader of the storage room and the consumer is then asked to complete the record by the stock-specific information. However, such an approach is error prone if several disks are newly arrived at the same time in the storage room; In this case, the consumer may incorrectly associate the stocker-specific information with the volume-specific information. If several objects are to be re-stored at the same time, it is therefore advantageous to provide a reading device with which the data carrier-specific information of a specific data carrier can be read in in a targeted manner, in particular by placing a data carrier in the detection area of the reading device, and can be supplemented by the associated warehouse-specific information. This reader may be of the same type as the reader in the hold. However, in order to facilitate the consumer's control over which of several closely adjacent data carriers is read, it is advantageous if the data carrier has the information specific to him also in optically readable form, and the reading of the data carrier specific information is carried out optically. For this purpose, the already mentioned, built-in mobile data terminal camera can be used advantageously. Another advantage of the optical information acquisition is that the data carrier-specific information and the stock-specific information of a storage item can be contained in a common image and thus a single image can be sufficient for generating the record of a storage item.

Another object of the invention is a refrigerator, in particular a household refrigerator, with a storage room and a reader for non-contact reading of data carriers, which is arranged on the storage room to read located in the storage room disk.

The reader and the storage room may be surrounded by a common shield to ensure that the reader can only read data carriers that are actually in the storage room.

The storage room can be assigned to illuminate a part of the storage space several selectively controllable bulbs.

Still further objects of the invention are a management unit, which is networkable with a reader of a refrigerator and a mobile data terminal and is adapted to perform at least the steps c) to e) of the method described above, and a computer program product with program code means enable a computer to work as the administrative unit described above.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

1 Components of a system for carrying out the method according to a first embodiment of the invention;

2 a flowchart of the method;

3 Components according to a second embodiment of the invention; and

4 the application of the invention to a storage room outside a refrigerator

1 shows a refrigerator 1 , here a combination household refrigerator with a freezer 2 and a normal refrigerator 3 , Both subjects 2 . 3 can be considered together as a storage space in the sense of the above description. The following example illustrates the case that each subject 2 . 3 forms such a storage room for itself.

At every subject 2 . 3 are RFID transmitter / receiver 4 Readers are mounted for communication with RFID tags of refrigerated goods stored in the compartments. The transmitter / receiver 4 can have directional transmission / reception characteristics, so that they - especially when mounted in a partition 5 between the subjects 2 . 3 - in each case only one of the subjects 2 . 3 send or receive from this. Alternatively or additionally, the subjects 2 . 3 can be shielded from each other, for example by a metallic evaporator in a partition 5 between the subjects 2 . 3 so that every sender / receiver 4 only receives signals of the tags in its compartment.

Runtime, phase or intensity differences between signals coming from a same day at different transceivers 4 arrive, allow a conclusion on the position of the tag relative to the transceivers 4 , Two transceivers 4 suffice to make a circle around a the transmitter / receiver 4 To indicate the connecting line on which a day must be. For a small compartment like the freezer 2 can have two transmitters / receivers 4 , which are preferably arranged on opposite walls of the compartment, sufficient to locate a day in the compartment so accurate that a user can find it quickly and safely based on the location result. For a large compartment, especially a compartment with several shelves 6 like the normal refrigerator 3 , are three transmitters / receivers 4 desirable to be able to specify three location coordinates of a tag.

An interior lighting of the compartments 2 . 3 each includes a plurality of individually controllable bulbs 7 , here for example in the form of a matrix of OLEDs attached to the shelves 6 , at the bottom of the partition 5 or on the ceiling of the compartment 2 is arranged to selectively illuminate refrigerated goods on an underlying footprint.

The transmitter / receiver 4 are with an administrative unit 8th connected. The administrative unit 8th can in the refrigerator 1 be installed. Im in 1 As shown, it is out of the refrigerator 1 outsourced and with the transceivers 4 over a network 9 connected. For example, the administrative unit 8th to be implemented on a PC that belongs to the same household as the refrigerator 1 heard and with its transceivers 4 eg connected via WLAN. It can also be a computer of a service provider, in which case the network 9 a public telecommunications network or the Internet.

To the same network 9 is a mobile device 10 such as a smartphone or a tablet PC connected. The mobile device 10 has a built-in camera in a conventional manner 11 , a display screen 12 and an interface 13 for entering alphanumeric information.

To the accessories of the refrigeration device 1 heard a set of RFID tags 14 , These can be provided in different forms, for example in the form of inexpensive stickers 15 , which can be attached to any solid surface, such as disposable packaging and disposed of after consumption of the contents together with the packaging. Other tags 14 are durable on reusable refrigerated goods 16 or reusable clips suitable for sealing freezer bags 17 appropriate. Every day 14 stores a TID specific to it, distinguishing it from all other tags.

A database 18 the administrative unit 5 contains to every day 14 who is in one of the subjects 2 . 3 finds a record 19 with several entries 20 to 25 , The entry 20 contains the TID of the tag 14 , The entry 21 contains information on refrigerated goods, with which the relevant day 14 physically connected. The entry 22 specifies the subject 2 or 3 in which is the day 14 is; he may be missing if every subject 2 . 3 a separate database is assigned. The entry 23 specifies the coordinates of the tag 14 or the associated with him refrigerated goods in the subject 2 or 3 , The function of the entries 24 . 25 . 26 will be explained in connection with the description of the method.

This in 2 The method shown starts at a time when the user of the refrigerator 1 decides to buy supplies. With his mobile device 10 In step S1, he contacts the administrative unit 5 on to the database 18 view. He can from the administrative unit 8th all records 19 but it is also conceivable, in step S1, a search filter to the administrative unit 5 to submit, so that in step S2 only certain records 19 to the terminal 10 For example, the user may selectively select the records depending on the department of a supermarket in which he is currently located 19 to fresh fruits and vegetables, to meat and sausages or to dairy products, so fast identify which products from that department may need to be taken care of.

These steps can be repeated several times until the user completes all his purchases.

Then the user loads his purchases at home into the refrigerator 1 one. For this he chooses to every product that does not already have a day 14 the manufacturer brings a suitable type of tag 14 off (S3). For packaged products where refilling would compromise shelf life, such as fresh milk, yogurt, or the like is a sticker tag 15 suitable, which is glued on the packaging of the product. For fresh produce such as cheese or cold cuts, which are usually packed in bags in the supermarket, a clip can be used 17 with day 14 or they are placed in a container 16 transfilled with tag. Thus, the user finally has a plurality of chilled goods, each with a day 14 are provided.

Connecting to an RFID tag 14 is unnecessary for those products purchased by the user, already from the manufacturer with such a tag 14 have been equipped. Such tags may contain the same article-specific information as the bar codes conventionally collected at supermarket cash registers to determine the purchase price to be paid by the customer and to monitor the inventory of the items in the supermarket.

The user has various options for the next step S4 for each of these chilled goods in the database 18 a record 19 to apply. When the mobile terminal 10 Supporting NFC communication, it can be so close to a day 14 Keep that information TID directly on the radio path from the day 14 to the terminal 10 is transmitted. In the subsequent step S5 on the with the day 14 characterized refrigerated goods related information in the terminal 10 he can enter its interface 13 use, or he does with the camera 11 a photo of the chilled goods.

In step S6, the TID and the refrigerated goods-related information are sent to the database 18 passed on and there in a common record 19 as entries 20 . 21 stored. The entry 24 This data record is set to a value that does not yet affect the refrigerated item in question in the refrigeration unit 1 recorded.

In the entry 25 the current date and time can be noted. However, it is preferred that the administrative unit 5 based on the entry 21 ie the refrigerated product-specific information entered by the user in step S5 or the information derived therefrom in S6, automatically, possibly taking into account the entry 22 , estimates a recommended maximum shelf life of a refrigerated item, adds it to the date of storage, and the result in the entry 25 of the record 16 this cooling object stores (S7).

If as refrigerated goods related information only from the camera 11 generated image, or in addition to that of the user via the interface 13 entered information can be provided that the administrative unit 8th in step S7 further derives a text information or classification information describing the refrigerated goods from the image, based on which the next time the user purchases the new entries 19 can be searched with the help of filters and selectively transmitted in step S2. This derivation may be based on the recognition of characters, bar or QR codes visible in the image; It is also conceivable that the administrative unit 8th to the transmitted image similar images on the Internet research to close from linked with these images keywords on the subject matter displayed and so have a text information available, which later repeating the step S2 with lower bandwidth than a picture to the terminal 10 can be transferred and displayed there on a small display area.

A preferred embodiment of the invention is the information TID of each tag 14 also in optically readable form, eg as bar code or QR code on the surface of the tag 14 printed. Then the user can take pictures of them with the camera 11 takes a picture of the refrigerated goods, so that the above-described steps S4 of detecting the TID and S5 of detecting the refrigerated goods specific information for the user by the taking of a single photo are done. Extracting the TID in binary form from the image data may then be done by the management unit 8th be done using known methods of electronic image processing.

The steps S4-S6 and possibly S7 are for each with a day 14 provided Kühlgutstück repeated.

Having records in this way 19 for all new chilled goods have been created, the user loads them into the refrigerator 1 one. When he is done, he closes the door of the refrigerator 1 , If the administrative unit 8th it recognizes this in step S8, it starts via the transceiver 4 the RFID tags 14 in the subjects 2 . 3 to address and query their TID.

If the TID is one of the tags in the refrigerator 1 is received, the administrative unit checks 8th in step S9, if this TID is in one of the records 19 the database 18 is included. If yes, and if the entry 24 This record the associated Kühlgutstück as in the refrigerator 1 recorded (S10), then it is refrigerated goods, even before opening the door in the refrigerator 1 has been; no further action is required in this case, and the process returns to step S9 to process another received TID.

If the entry 24 the chilled goods as not in the refrigerator 1 recorded, then it is one of the new refrigerated goods. In this case, the entry becomes 24 changed to "recorded in the refrigeration unit" (S12), in the entry 22 becomes the subject 2 or 3 noted by its transceivers 4 the TID was received, and based on runtime differences from those of the different transceivers 4 of the subject concerned 2 or 3 received signals become coordinates of the tag 14 from which the TID originated, calculated. In step S13 are in the entry 23 these coordinates themselves or derived from these coordinates designation of one or more lamps 7 noted that are needed to illuminate an object with the calculated coordinates. Thereafter, the process returns to step S8 to process another TID, if any.

If the TID in any of the records 19 contained, then it must come from a chilled product, whose day 14 has not previously been subjected to steps S4-S6 or in which the printed TID has been detected incorrectly. In this case, the administrative unit sets 8th in step S12, a new record 19 to the TID as an entry 20 contains. If the TID is from a tag attached to a product by the manufacturer 14 comes from, then that can for the entry 21 required product-related information also from the day 14 read or over the network 9 be queried from a publicly accessible database; in this case, the record becomes 19 supplemented with the information thus obtained, and the administrative unit 8th returns to step S8 to process another TID, if any. If no product-related information can be obtained in the way described, then the TID most probably comes from one day 14 forth, the user himself has connected as described above with the chilled goods. Therefore, the administrative unit generates 8th in step S14, an error message to the terminal 10 or to a user interface of the refrigeration device 1 sends.

If the user does not respond, the process returns to step S8 to process additional TIDs, possibly generating further error indications. If the user decides to open the door of the refrigeration appliance in response to an error message, this is done by the administrative unit 8th detected in step S15, and the management unit 8th in step S16, only those lamps switch 7 one, those tags 14 illuminate, which have been the cause of a mistake. The user can now specifically remove the illuminated chilled goods again and repeat the steps S4, S5 on them (S17), whereupon the administrative unit 8th the data set created in step S12 supplemented with the information thus obtained.

If the user after this treatment, the affected refrigerated goods in the refrigerator 1 reset and the door closes again, this leads to the return of the method to step S8.

If a predetermined waiting time has elapsed after the last closing of the door, the process reaches step S18. This waiting time is typically longer than that which remains refrigerated during a meal outside the refrigerator, for example 2h. After this time, in step S18, all records are 19 deleted, their entry 24 still on "not in the refrigerator 1 recorded "is set.

If the user objects from the refrigerator 1 takes them out for a meal and closes the door again, this is also done by the administrative unit 8th and returns to step S8. The removed items are recognized in S9 by their tags 14 no TID to the administrative unit 8th can deliver; accordingly, in their records 19 the entry 24 set to "not included in the refrigerator".

After the meal, the unused refrigerated goods are returned to the refrigerator, and in turn the process returns to step S8. Because for all returned items a record 19 with the correct TID, steps S10, S11 are respectively passed through for these objects; Data input by the user is not required.

Items that have been consumed and are therefore not returned can not send a TID to the management unit in step S9 8th deliver. Your entries 24 therefore remain on the status "not in the refrigerator 1 with the result that they are cleared at the next execution of step S18. When the day 14 of such an article, eg after rinsing and refilling the container 15 to which it is appropriate to be reused, a new record can be created for it in steps S4-S6 become. If he is in the refrigerator 1 passes without having previously gone through these steps, it is recognized as foreign in S9 and triggers the error message S14.

Regardless of the stage in which the method described above is, the administrative unit examines 8th every time the door of the refrigerator 1 is opened (S19), the entries 24 . 25 the records 19 to check (S20). If in step S20 a record 19 is found, whose entry 24 is set to "contained in the refrigerator" and in which the entry 25 the recorded date is already reached or will be reached within a predetermined period of time, and thus immediately corresponds to consumable refrigerated goods, then the administrative unit 8th towards this refrigerated goods by highlighting the relevant refrigerated goods highlighted for at least a time after opening the door (S21), for example by doing so according to the entry 23 this item to be cooled lighting bulbs 7 operates while other bulbs remain off, giving it higher intensity than other bulbs 7 or blinking.

It can also be provided to carry out the examination of step S20 independently of the opening of the door from time to time in order, if immediately to be used refrigerated goods is determined, a related note to the terminal 10 to send. If the hint the entry 21 is added to the record in question, the user can recognize what refrigerated goods it is without him for the refrigeration device 1 must visit.

Alternatively, in addition to the above-mentioned status, "not in the refrigerator 1 recorded "or" recorded in the refrigerator "a third status can be defined to identify a removed and probably used refrigerated goods, and in step 18 is not deleted in the record of a non-reloaded chilled goods as described above, but set to this third status. Then, if at a later date the RFID tag 14 whose TID is the entry 20 This record resembles, again in the refrigerator 1 is found, a request is issued to the user, whether the old record 19 including its chilled entry 21 continue to be used or a new record should be created.

Put each one properly in the refrigerator 1 introduced day 14 assigned in step S6 and in the entry 25 noted date does not change as long as the corresponding record 19 consists. The user can use this date in step S1 as a query criterion in order to recognize which refrigerated goods are the longest in the refrigeration appliance and should possibly be consumed as soon as possible.

Selective lighting by built-in refrigeration bulbs is well suited as a method for pointing to a specific refrigerated goods when Kühlgutstücke, as in a refrigerator usually the case, placed separately on a floor space and individually illuminated. If refrigerated goods are tightly packed, as is often the case in a freezer, selective lighting may fail due to the fact that a refrigerated item to be pointed out can not be illuminated because another item of refrigerated goods is located between it and the illuminant. 3 shows the transfer of the invention to such a case using the example of a freezer as a refrigerator 1 , The field of expertise 2 the freezer is shown here empty for the sake of simplicity except for a chilled goods 26 to be pointed out, be it because the administrative unit (not shown) 8th the freezer storage time of this Kühlgutstücks 26 has expired or is about to expire, or because it has been detected by the user on the mobile device 10 entered search key corresponds. Several transmitters / receivers 4 on the walls of the compartment 2 allow localization of the chilled goods 26 in three dimensions. Since the removal of a Kühlgutstücks from the freezer can change the coordinates of many other Kühlgutstücke, they are preferably, deviating from the representation of 2 , after each closing of the lid for all chilled goods in the compartment 2 newly recorded.

When the mobile terminal 10 in response to a search key entered by the user or at the initiative of the administrative unit 8th due to expiring storage time of the chilled goods 26 at least the entries 21 . 23 from its record 19 shows it on its display screen 12 a schematic representation of the freezer, in which one of the position of the Kühlgutstücks 26 corresponding, with 26 ' respectively. 26 " designated point is highlighted.

The terminal 10 is here equipped in a manner known per se with a tilt sensor to be held vertically 10 Terminal as a map 1' . 1" to clarify the position of the chilled goods 26 a front view or with horizontally held terminal 10 to show a top view. By the user between the two cards 1' . 1" he obtains information about the location of the refrigerated goods to be found 26 in three dimensions and can thus find it fast and targeted among a large number of other pieces.

The above-described methods for acquiring and processing information about stored goods are not only applicable in a refrigerator. 4 shows as an ad on the screen of a mobile device 10 , An overview of a storage room, here is a view of a wall of a storage room, where a refrigerator 1 between shelves 27 . 28 is set up. Transmitter-receiver 4 ' are on both sides of the shelves 27 . 28 mounted and communicate with the administrative unit 8th via a repeater 29 and a network interface on the refrigeration device 1 , The transmitter / receiver 4 ' could in principle also for detecting the position of refrigerated goods within the refrigerator 1 be used. Since then, however, measurement inaccuracies could lead to refrigerated goods, which are in fact in one of the shelves 27 . 28 located inside the refrigerator 1 is localized and vice versa, and this would not only significantly hinder the finding of the refrigerated goods, but would also lead to a wrong assessment of the storage life of the refrigerated goods, are the outer walls of the refrigerator 1 preferably against the signals of the transmitter / receiver 4 ' shielded and transmitter / receiver 4 for localizing refrigerated goods in the refrigeration appliance 1 mounted inside the shield. The dimensions of the shelves 27 . 28 need in the administrative unit 8th not to be entered; the positions of the shelves 27 . 28 and the height of their shelves can be the administrative unit 8th determine during use from the positions of stored goods on the shelves. Stored goods inside and outside the refrigeration appliance 1 are in the same database 18 recorded. When a user makes a request for the location of a particular stored asset 26 , eg a bottle of wine, to the administrative unit 8th and then the corresponding entries from the record 19 this bottle on the terminal 10 gets transferred, this can show him exactly where in the refrigerator 1 or the shelves 27 . 28 the bottle is.
