Title: Storage Facility for Articles Having a Load State Device and a User Detection Device

Description:
BACKGROUND 
     The present disclosure relates to a storage facility for articles, comprising at least one load state detection device, and to a computer network having such a storage facility and a method for detecting a user of such a storage facility by means of the user detection device. 
     SUMMARY AND INITIAL DESCRIPTION 
     Storage facilities are known in the state of the art in the form of shelves, refrigerators, cupboards, and the like, and storage facilities are used both in private households and in shops, for example, to store articles and present them for sale. 
     A special type of storage facilities are refrigeration appliances. Refrigeration appliances or refrigerators are known in the state of the art in various embodiments. In addition to classic refrigerators for domestic use, chest freezers, refrigerated display cabinets, minibars and the like are known, for example, that can either be closed by means of a door or are open and will hereinafter all be referred to as refrigeration appliances. 
     For example, from DE 10 2007 032 052 A1 a device for regulating the power consumption of an electrical appliance is known, wherein information provided by the electrical appliance, for example, by temperature measurement devices of a refrigerator, can be sent to a control device. 
     JP 2006 345 144 A describes a monitoring device for appliances that comprises at least one sensor for detecting that the appliance is opened or closed, a vibration, a sound, and further data, wherein the monitoring device can transmit data of the appliance to other appliances by means of a data transmission device. 
     Detection systems for detecting a load state of a storage facility are also known in the state of the art. From WO 2005/015510 A1, a detection device having a sensor arrangement is known which may, for example, comprise piezoelectric weight sensors, a digital image recording system, infrared switches and/or laser sources having digital detectors for detecting a load state of a refrigeration appliance. 
     WO 2007/128572 describes a system for monitoring a storage of articles, wherein the system comprises a sensor for monitoring the opening or closing of a door and at least one weight sensor, wherein the system comprises a plurality of containers and each container is in operative connection with a weight sensor, and wherein the weight of a container is measured at a predefined time after the door of the container is closed. 
     From DE 20 2008 015 892 U1, a container having an RFID sensor for detecting an article provided with an RFID chip is known, wherein the container detects that an article is removed from or placed in the container, and wherein a weighing apparatus additionally measures the weight difference caused by removing an article from or placing an article in the container. 
     DE 10 2005 054 333 A1 discloses a refrigeration appliance having a plurality of storage places for articles to be stored in a storage compartment as well as a detection device for detecting the load state of a storage compartment, wherein the detection device has at least one separate sensor for detecting the state of occupation of each of the storage places in the storage compartment. Each of said sensors comprises a capacitor which is arranged such that a change in the state of occupation of the storage place associated with the sensor causes the capacity of the capacitor to change. 
     From DE 10 2005 052 952 A1, a refrigeration unit having a goods compartment for industrially manufactured refrigerated products is known, wherein the refrigeration unit comprises a load cell which is arranged below the refrigeration unit and has a strain gauge for measuring the weight of the refrigeration unit. 
     From EP 1 152 315 A2, a device and a method for monitoring and controlling a temperature of a refrigeration appliance are known, wherein the system comprises a temperature sensor and information of the refrigeration appliance is transmitted to a data processing device by means of a wireless data transmission device. 
     In general, it is known in the state of the art to determine the load state of a storage facility of a refrigeration unit by measuring its weight. However, in the state of the art the load state can only be determined if the storage facility is loaded with one particular type of article, and no differentiation can be made between individual batch sizes or container sizes. It can only be determined that a particular amount of one type of article is removed from the storage facility or placed in the storage facility. 
     According to the state of the art, complex load state detection devices or individual, additional identifications of the articles and special evaluating devices are required to precisely identify the articles that are removed, placed and/or stored. In the state of the art, an individual load state detection device is provided for each article or each group of articles in order to determine the load state of a storage facility. As an alternative of the state of the art, the articles themselves are provided with an identification, for example, an RFID chip, that can be detected by a special evaluating device in order to determine the load state of a storage facility. 
     However, the devices known from the state of the art have the drawback that no user behavior is detected during a removal from and/or loading of a storage facility. The fact that no user behavior can be detected or is detected is disadvantageous with a view to optimizing logistics processes, for example, an optimum restocking of a storage facility. User behavior may, for example, be used to predict that particular articles will possibly be removed in the future, so that an optimum restocking of the storage facility with articles can be ensured, in particular in case of longer delivery times, and future user behavior can be predicted based on the user behavior that has been detected. 
     The object of the present disclosure is therefore to eliminate the drawbacks of the state of the art. In particular, it is intended to provide a storage facility that allows to precisely detect a behavior of a user of the storage facility. 
     This objective is achieved by means of at least one user detection device that is designed and configured to detect a time period of at least one user in front of the storage facility, a time period until at least one article is removed from and/or loaded into the storage facility by the at least one user and/or a time period of at least one user in front of the storage facility without removal from and/or loading of the storage facility, and a load state detection device that is designed and configured to detect that something is loaded into and/or removed from the storage facility. 
     An integration of a user detection device according to the present disclosure into a storage facility has in particular the advantage that the behavior of a user can be precisely detected. This is particularly advantageous as it allows to determine at which times articles are removed from the storage facility. Based on this data, it can then, for example, be determined according to the present disclosure on which days of the week and at which times more products and which types of products are removed in order to optimize restocking of the storage facility based on a load state of the storage facility. 
     A user detection device according to the present disclosure can thus serve to optimize the supply chain of the storage facility with products, thus ensuring that the user detection device is sufficiently loaded at all times.

To be able to determine the load state of a storage facility with at least two different products, very precise measured values of the weight of the storage facility are required. However, devices of the storage facility may affect the weighing apparatus. For example, the vibrations of a compressor of a refrigerator affect the result of the weight measurement.

     Finally, the refrigeration appliance may be operated using a refrigeration device in the form of a compressor, wherein in particular no data of the weighing apparatus is evaluated by the evaluating device when the compressor is switched on to effect refrigeration of the refrigeration appliance. 
     The present disclosure is thus based on the surprising finding that it can be possible to detect a behavior of a user by means of a load state device and a user detection device that detects a time period of at least one user in front of the storage facility. As an alternative or additionally, a time period until at least one article is removed from and/or loaded into the storage facility by the at least one user is detected. Furthermore, alternatively or additionally a time period of at least one user in front of the storage facility without removal from and/or loading of the storage facility may be detected. The fact that something is removed or loaded is detected by the load state device in each case. 
     In this context, the user detection device is preferably arranged above a reach-in area of the storage facility and may, for example, comprise a motion detector, a light sensor, an infrared sensor and/or a radar module to detect a user. In this context, a reach-in area can be the area of a storage facility that allows a user to place articles in or remove articles from the storage facility. It may be possible to close the reach-in area, for example, by means of a door. The user detection device thus serves to determine whether and how long a user is or has been in front of a storage facility before removing an article from and/or loading an article into the storage facility and/or whether nothing is removed and/or loaded. In this context, it may be advantageous to store in a memory at which time, in particular on which date and at which time of day, a user removes something from and/or loads something into the storage facility. It may also be advantageous that data of the user detection device can be sent to the server and/or retrieved from the server. 
     A user detection device according to the present disclosure thus serves to obtain information relating to a time a user spends in front of the storage facility before deciding to remove and/or load something. 
     In this context, it may be advantageous that the user detection device is arranged in the upper half, preferably on the front side, of a storage facility. In particular, it may be advantageous that the user detection device is arranged in a cover area. A cover area can, for example, be a covering of the storage facility that is arranged so as to cover technical equipment above the reach-in area of the storage facility. 
     A storage facility according to the present disclosure thus allows, for example, to optimize supply chains of articles. In addition to detecting whether and when an article has been removed from the storage facility, it is possible to determine a change in user behavior. This may, for example, be advantageous when new articles, for example, a new beverage, preferably a new beverage in a beverage can, is first introduced to the market. The user detection device according to the present disclosure can detect within which time period, at which time and on which date a user decides to remove the new beverage can. Based on the detection of this data, it can be predicted when the next delivery will have to be made and how many articles are to be delivered. 
     Furthermore, it may be advantageous that the storage facility has a weighing apparatus to determine the weight of the storage facility. In this context, it may be advantageous that a load state of the storage facility with a plurality of different articles can be determined by precisely determining the weight of the storage facility alone. Furthermore, a precise measurement of the change in weight of the storage facility allows to determine that an article is removed from the storage facility or an article is loaded into a storage facility. 
     To this end, according to the present disclosure a weighing apparatus may continuously detect measured values representative of a weight of the storage facility, and an evaluating device that may preferably be designed in the form of a data processing device, may determine the weight of the storage facility based on the measured values of the weighing apparatus. In this context, it has been found to be advantageous that the weight of the storage facility is not determined when the measured values of the weighing apparatus are affected by devices of the storage facility. 
     For example, it has been found to be advantageous that the evaluating device of a loading device in the form of a refrigeration appliance does not evaluate data of the weighing apparatus when a refrigeration device of the refrigeration appliance affects the measured values of the measuring device. In this context, only a refrigeration device not comprising a compressor may, for example, be used, for example, an adsorption refrigeration device. If a compressor refrigeration device is used, vibrations of the compressor could affect the measured values of the measuring device during operation. In this context, it has been found to be advantageous that in case of a refrigeration appliance having a compressor refrigeration device the measured values are only evaluated at certain times, for example, when a compressor is not operating, or that the compressor is mechanically separated from the measuring device, so that the compressor is supported in particular in a vibration-free manner relative to the measuring device. In both possible configurations according to the present disclosure, the compressor refrigeration device can thus be prevented from affecting the measured values, and it can thus be precisely determined which articles are removed from and loaded into the storage facility. 
     According to the present disclosure, a weighing scale, in particular a mechanical, electronic and/or electromechanical weighing scale, may be comprised by the storage facility as a weighing apparatus, wherein the weighing apparatus measures or detects the weight of the storage facility with a high measurement accuracy. In this context, it may be advantageous that the weighing apparatus has a weighing range from 0 kg to 200 kg with a measurement accuracy in a range from one nanogram to one gram, particularly preferred in a range from one nanogram to one microgram. 
     Such a precise determination of the weight of the storage facility requires that the measured values of the weighing apparatus are not affected by other devices of the storage facility; in particular, devices of the storage facility that, for example, vibrate must not be active. Such vibrations may distort the measured values of the weighing apparatus. Of course the measured values of the weighing apparatus may also be distorted by other devices of the storage facility, so that the measured values of the weighing apparatus should also not be evaluated by the evaluating device when these devices are operating. 
     A high measurement accuracy according to the present disclosure may, for example, be achieved by means of a weighing apparatus comprising at least one load cell, preferably four load cells, wherein each of the load cells preferably comprises one strain gauge, in particular four strain gauges that are arranged in the form of a bridge circuit, preferably a Wheatstone bridge. A bridge circuit in the form of a Wheatstone bridge can, for example, allow to precisely measure the weight of the storage facility if the electric resistances of the Ohmic kind of the strain gauges are evaluated. In this context, each two strain gauges or their resistors form a voltage divider, and two voltage dividers are arranged parallel to each other. A voltmeter relates the voltage dividers to each other, so that the measured parameter of the arrangement is a voltage difference between the voltage dividers, also referred to as diagonal bridge voltage. This Wheatstone bridge has in particular the advantage that the resistors of the strain gauges that are sensitive to expansion and whose resistance will increase or decrease depending on the deformation of the resistors, complement each other in the same direction. However, temperature changes or the like do not affect the measurement result as they have the same effect on all strain gauges and neutralize each other. 
     In this context, it is preferred that the load cells and/or the strain gauges of the load cells are arranged below the storage facility, in particular in the area of feet of the storage facility. In this context, it may be advantageous that the strain gauges are arranged underneath the feet or between the feet and the body of the storage facility. 
     A load state of the storage facility may thus be determined based on the weight of the storage facility, wherein, based on a change in weight of the storage facility, it can be determined, for example, that an article is removed from the storage facility or an article is loaded into the storage facility, wherein it is in particular also possible to determine the type of article and the number of articles. 
     Also, according to the present disclosure it may be possible to determine a load state of the storage facility directly from the weight of the storage facility. In this context, the weights of the articles located in the storage facility may advantageously be stored as reference values in a memory of the storage facility and/or a memory that is in operative connection with the storage facility. 
     It is also preferred that a change in weight of the storage facility is used to determine the type of article that is removed from and/or placed in the storage facility and the number of articles concerned. In this context, the change in weight can be compared with the weights of the articles stored as reference values. Also, it is preferred that the time when something is removed from and/or loaded into the storage facility is stored in a memory. 
     For example, according to the present disclosure articles in the form of food items, in particular in the form of beverage cans or bottles, may be stored in a storage facility. When a user, in this exemplary case a consumer, removes, for example, a beverage can from the storage facility, the weight of the storage facility will change due to the removal of the can. In the memory of the storage facility, a reference value for a weight of each type of can located in the storage facility is stored, so that the number and type of cans that have been removed can be determined based on the change in weight of the storage facility caused by the removal. If a precision weighing apparatus is used that is preferably comprised by the storage facility, not only cans differing in volume can be determined but, due to the different specific weight of different beverages, also the type of beverage that has been removed. For example, it can be detected whether a particular beverage in the can removed from the storage facility in the example contains sugar or not as the storage facility according to the present disclosure can even detect such small differences between the specific weights of the beverages and thus of the cans. A crucial factor in such a precise measurement of the weight of the storage facility is the fact that devices of the storage facility do not affect the measured values of the weighing apparatus. 
     Also, according to the present disclosure the storage facility may comprise a data processing device, in particular a computer, wherein the evaluating device and the data processing device may be designed as one unit. In this context, it may be advantageous that the storage facility comprises a data transmission device in order to transmit data to a further data processing device, for example, a server, a mobile phone or the like. Preferably, data may be transmitted from the storage facility to a further data processing unit via a wire-based or wireless network and/or using a mobile communication standard, in particular the GSM and/or UMTS standard. 
     In this context, according to the present disclosure the storage facility may also be in operative connection with a server, wherein data can be sent from the storage facility to the server and/or retrieved from the server and vice versa. In this context, it may be advantageous that the server is in operative connection with further terminals and/or another server, in particular that the server makes available information or data from the storage facility to a user, for example, displays said information or data on an output device and/or transmits a message to the user, for example, in the form of an e-mail, an SMS, an MMS and/or a push message. 
     Also, the storage facility may comprise an input device that, for example, allows a user to operate the storage facility and/or to provide and/or retrieve data and/or information of the storage facility. In this context, an input device according to the present disclosure may, for example, be provided in the form of a keyboard, a mouse, a touch screen and/or the like. 
     Furthermore, it may be advantageous that the storage facility has a position detection device to determine an actual position of the storage facility. Such a position detection device according to the present disclosure may, for example, be provided in the form of a GPS receiver and/or a device for cell site location tracking. In this context, a desired position of the storage facility may be stored in a memory, and it may be possible at all times to compare the actual position of the storage facility with the desired position, and/or said comparison of the actual position with the desired position may be made automatically, for example, in real time and/or at regular intervals. The desired position can be predefined at the discretion of a user and changed when required. 
     In this context, a difference between the actual position and the desired position of the storage facility may be displayed to a user on a display device of the storage facility and/or on a display device that is in operative connection with the server, and/or the storage facility and/or the server may inform a user of said difference by means of an SMS, an MMS, an e-mail and/or a push message. 
     Such a position detection device has in particular the advantage that it allows to display where a storage facility is located. If the actual position of the storage facility is found to differ from a desired position of the storage facility, a user can be informed immediately. An operator of a storage facility according to the present disclosure can thus check, for example, whether the storage facility continues to be in the desired position in a shop. 
     According to the present disclosure, the storage facility may also comprise an operating state detection device. The operating state detection device can detect whether a storage facility is in a switched-on or switched-off state and/or whether the storage facility is malfunctioning. In this context, a desired operating state of a storage facility may be stored in a memory, and the desired operating state may be compared with an actual operating state continuously and/or at intervals. If the actual operating state is found to differ from the desired operating state, the difference can be displayed to a user by means of a display device, for example, a display device of the storage facility and/or a display device that is in operative connection with the server. Of course, a user may also be informed of the difference between the actual operating state and the desired operating state, either additionally or exclusively, by means of an SMS, an MMS, an e-mail, and/or the like. Such an operating state detection device has a number of advantages, some of which will, by way of example only, be explained below. 
     It can, for example, be defined in a memory at which time of day and on which days a storage facility should be operating. Such predefined operating times of the storage facility may, for example, be contractually agreed with a dealer. The operator of a storage facility can thus check whether a storage facility is operating at the agreed times. Also, maintenance and/or a repair of the storage facility can be made easier as a service centre and/or a service employee can be immediately informed of a malfunction of the storage facility. 
     Also, a storage facility may comprise at least one temperature measurement device to measure the temperature at least in an area of the storage facility. Advantageously, two or more temperature measurement devices may also be provided to measure a temperature in particular areas of the storage facility. The actual temperatures that have been measured can be compared with desired temperatures stored in a memory, and a user can be informed of differences between the actual temperature and the desired temperature. In this context, the data processing device of the storage facility and/or the server may compare an actual temperature with a desired temperature of the storage facility, and a user may be informed of the difference. It may be advantageous that the difference between the actual temperature and the desired temperature of the storage facility is displayed to a user on a display device, for example, a display device of the storage facility and/or a display device that is in operative connection with the server. 
     This has, among others, the advantage that the temperature of articles that should be stored cool, for example, perishable goods and/or articles that tend to taste better when they are cold, in particular beverages, can be checked. Furthermore, continuous storage of the at least one measured temperature serves to prove that a predefined maximum temperature of the articles located in the storage facility has not been exceeded. This may in particular be advantageous in case of food items. 
     Also, according to the present disclosure the storage facility may comprise at least one storage facility parameter, in particular representative of an installation site, a country, a customer group, a dealer, a dealer group, and/or an identification number for unambiguous identification of a particular storage facility. 
     It may also be advantageous that data from the user detection device, the at least one temperature measurement device, the operating state detection device, relating to the storage facility parameter and/or from the position detection device is regularly sent to the server and/or retrieved from the server. In this context, the data may be sent to the server and/or become retrievable from the server at regular intervals, in particular intervals of 30 minutes or 60 minutes. 
     Also, it may be preferred according to the present disclosure that the storage facility is designed in the form of a refrigeration appliance or refrigerator. In this context, the weight of the storage facility may in particular not be evaluated when a refrigeration device of the refrigerator is operating. Preferably, the refrigeration appliance is designed in the form of a compressor refrigerator, an absorption refrigerator, and/or a thermoelectric refrigerator. In this context, the weight of the refrigerator is in particular not evaluated when a compressor is active. 
     A refrigeration device, in particular a compressor of a refrigeration device, of a refrigerator causes vibrations that affect a precise measurement of the weight of the storage facility. The weight of the refrigerator can thus only be precisely determined when the refrigeration device is not active or if the measuring device is mechanically decoupled from the vibrations of the compressor. A refrigeration device of a refrigerator normally operates at intervals in order to reduce the temperature within a refrigerated area of the refrigerator when it exceeds a predefined threshold. While the temperature is below the threshold, the refrigeration device is not active or not operating. According to the present disclosure, the weight of the storage facility is of course not determined either when other devices of the storage facility affect the determination of the weight. 
     If, however, the measuring device is mechanically decoupled from the compressor, measured values can be detected continuously. However, complex technical measures are required to mechanically decouple the measuring device from the compressor in existing refrigeration appliances, whereas it is relatively easy to retrofit existing refrigeration appliances with a measuring device. 
     Therefore both approaches to improving the measurement accuracy of a measuring device are advantageous. 
     Also, according to the present disclosure the storage facility may have an open storage area, in particular an open refrigerated area, and in particular no door or the like for closing the storage area. 
     A storage facility according to the present disclosure thus allows to precisely determine a removal and/or loading as well as a load state of the storage facility, and to determine which articles are located in the storage facility and/or removed from or placed in the storage facility by measuring the weight of the storage facility alone. Furthermore, an operating state, an actual position and/or a temperature of the storage facility can be detected and preferably stored and optionally compared with desired values, and a difference from the desired values can be displayed to a user and/or a user can be informed of said difference. The user detection device according to the present disclosure also serves to evaluate user behavior, so that, for example, market research data can be obtained. 
     According to the present disclosure, a computer network comprising at least one storage facility according to the present disclosure and a server may also be provided. Such a computer network according to the present disclosure is preferably in operative connection with at least two storage facilities and comprises at least one output device for displaying information or data from the storage facilities. 
     For the purposes of the present disclosure, a computer network means not only a classic computer network comprising at least one computer and preferably at least one server. A computer network according to the present disclosure may also comprise data processing devices and data transmission devices that are, for example, comprised by mobile phones, storage facilities, for example, refrigeration appliances, or the like. For example, an exemplary computer network according to the present disclosure may exclusively comprise devices comprising data processing devices, without comprising a conventional computer. A computer network according to the present disclosure may, for example, preferably comprise devices that can provide and/or retrieve data or exchange, receive and/or send data by means of suitable network devices. For the purposes of the present disclosure, the term “computer network” can also mean a combination of data processing device(s) and data transmission device(s), servers, storage facility/facilities, such as refrigerators, and optionally further devices comprising data processing device(s). 
     In this context, the computer network may advantageously store data from the storage facilities after sorting them according to defined parameters, for example, in accordance with a storage facility parameter and/or an actual position of the storage facilities. 
     This has in particular the advantage that an overview of the installation sites, i.e. the actual positions, of the storage facilities can easily be displayed to a user with reduced technical effort and minimal use of resources. 
     In this context, it may in particular be advantageous that the server receives and/or retrieves data from at least one of the storage facilities, in particular automatically, wherein at least one of the storage facilities transmits data from a user detection device, a temperature measurement device, an operating state detection device, relating to a storage facility parameter and/or from a position detection device to the server, and the data is sorted and/or stored in accordance with an installation site, a country, a dealer, a customer group, a dealer group and/or an identification number and shown, in particular on an output device, by the server. 
     A storage facility, according to the present disclosure and/or a computer network according to the present disclosure, thus allow(s) to centrally monitor a plurality of storage facilities with simple means, wherein a load state of the storage facility, a removal from and/or loading of the storage facility and a user behavior can be detected and evaluated, as well as information relating to the operating state, the temperature, the actual position and/or further information of the storage facilities. 
     Furthermore, user behavior can be evaluated in detail, so that precise data relating to user behavior can be taken into account, for example, for optimizing a supply chain. It can be detected how user behavior changes in accordance with an installation site, a time and/or a date, and these changes can be taken into account when adapting supply chains, marketing, installation sites, and/or the like.

     DETAILED DESCRIPTION 
       FIG. 1  shows a storage facility  1  in the form of a refrigeration appliance. Said storage facility has a refrigeration device  3  and a refrigerated area  5  as well as a weighing apparatus  7 . As shown, the weighing apparatus  7  can comprise four strain gauges that are arranged underneath the feet  8  or between the feet  8  and the storage facility  1 . 
     The weighing apparatus  7  serves to detect the weight of the storage facility  1 , that is evaluated by an evaluating device (not shown) at defined times. To be able to determine whether an article, which type of article, and how many articles is/are removed from the storage facility  1  or loaded into the storage facility, the measured values of the weighing apparatus are evaluated, wherein the measured values used to determine the weight of the storage facility  1  are not evaluated by the evaluating device (not shown) when the measured values of the weighing apparatus  7  are affected by other devices of the storage facility  1 . In particular, the weight of the storage facility  1  is not to be evaluated when the refrigeration device  3  is operating. A refrigeration device  3  normally comprises a compressor (not shown). When the refrigeration device  3  is operating to cool the refrigerated area  5 , the compressor will vibrate, thus causing the storage facility  1  to vibrate, so that the measured values of the weighing apparatus  7  are distorted. Alternatively, it is of course possible to provide refrigeration devices that do not need a compressor, such as adsorption refrigeration systems. As another alternative, the refrigeration device  3  may be mechanically decoupled from the weighing apparatus  7 , so that vibrations of a compressor of the refrigeration device will not affect the measured values of the weighing apparatus  7 . To be able to accurately determine the weight of the storage facility  1 , i.e. according to the present disclosure, no measured values of the weighing apparatus  7  are to be evaluated by the evaluating device (not shown) in this exemplary embodiment using a compressor refrigeration device that is not mechanically decoupled when the refrigeration device  3  is operating or another device of the storage facility  1  affects the measured values of the weighing apparatus  7 . 
     Furthermore, the storage facility  1  comprises at least one temperature measurement device  9  and a display device  11 . The display device  11  is, by way of example, designed in the form of lighting means  12 . Of course, additional or alternative display devices may be provided, for example, a display (not shown). 
     In an upper area of the storage facility  1 , a user detection device  13  is arranged that detects a user in a defined area in front of the storage facility  1 . In this context, it can in particular be detected at which time and on which date a user (not shown) spends a particular time period within the user detection device, and whether the user (not shown) removes articles from the storage facility  1  and/or places articles in the storage facility  1 , and if so, how many. In this context, it is preferred that the data of the user detection device  13  is stored in a memory (not shown). 
     Also, the storage facility  1  may have a holding device  15  for articles, in particular a holding device  15  for food items, preferably beverage cans and/or bottles. 
     According to the present disclosure, it may be advantageous that the storage facility  1  has a bottom area  17  where the refrigeration device  3  and/or further devices of the storage facility  1 , for example, a data processing unit (not shown), is/are arranged. 
       FIG. 2  shows a schematic plan view of the weighing apparatus  7  according to the present disclosure from  FIG. 1 . Said weighing apparatus  7  comprises 4 load cells  19  that are arranged below a bottom area  17  of the storage facility (not shown in  FIG. 2 ). The weight sensors used can be strain gauges (not shown). Of course, weight sensors other than the strain gauges shown in the figure can also be used. The strain gauges are, by way of example, arranged in the form of a bridge circuit, in particular a Wheatstone bridge, and the measured values of the weighing apparatus  7  or the strain gauges are evaluated by the evaluating device  21  at defined times. 
       FIG. 3  shows a principle view of a storage facility  23  according to the present disclosure. Said storage facility  23  comprises a weighing apparatus  25 , an evaluating device  26  for evaluating measured values of the weighing apparatus  25 , a position detection device  27 , a display device  29 , a user detection device  31 , an operating state detection device  33 , an input device  34 , and a temperature measurement device  35 . 
     In this context, data from the aforesaid devices  25 ,  26 ,  27 ,  31 ,  33 ,  34 , and  35  may in particular be processed by a data processing device  37 , in particular a computer. Also, the data processing device  37  may be in operative connection with a data transmission device  39 , and it may be possible to send information or data from the data processing device  39  to a server  40  and/or retrieve said information or data from the server  40 . 
       FIG. 4  shows a computer network  41  according to the present disclosure having three storage facilities  45  according to the present disclosure. Said storage facilities  45  comprise at least one data transmission device, so that data or information from the storage facilities  45  can be sent to a server  43  and/or retrieved from the server  43 . In this context, the server  43  may be in operative connection with at least one further terminal  47 , for example, a mobile terminal. Such a computer network  41  according to the present disclosure can make it possible that a plurality of information from storage facilities  45  can be displayed to a user with minimal use of resources. In particular, the information can be sorted and displayed in accordance with a particular storage facility  45 , an installation site of a storage facility  45  and/or a plurality of further parameters. 
     A computer network  41  according to the present disclosure thus allows to centrally detect a load state of storage facilities  45  as well as removals from and/or a loading of storage facilities  45  in real time, thus obtaining precise information on user behavior. Furthermore, the information can be used to optimize logistics processes, for example, supply chains and supply times, and detailed consumer data can be obtained. 
       FIG. 5  shows, by way of example, a plan view of a schematic scanning area  49  of a user detection device (not shown) according to the present disclosure. In this context, the storage facility (not shown) may in particular comprise a radar module that does not scan particular areas  51  within a scanning area  49  and only evaluates areas  53 . 
     The features of the present disclosure disclosed in the above description, the claims and the drawings can be essential, both individually and in any combination, to implement the present disclosure in its various embodiments.
