On the basis of a combination of said product and operational parameters the analyzing unit is able to configure the refrigeration power of the refrigerator. Therefore, according to the invention not only operational parameters, e.g. the cooling compartment temperature, but a combination of operational parameters and product parameters is used in order to adapt the refrigeration power when products are newly introduced into the cooling compartment. By means of said analyzing unit said refrigeration power can be aligned more exactly with said products introduced into said cooling compartment.

  • the refrigerator control may inform the user when the refrigerator is running out of food the user desires to have.
  • the refrigerator control can be able to warn the user about possible oversights, for example if the refrigerator door has been forgotten opened.
  • the main controller may be in a wireless connection with a monitoring unit. In this case, said main controller may provide remote information to said monitoring unit, such as the food available to the user, to the technical service with technical information, etc.
  • the monitoring unit or the main controller may store statistical information about the food log, the amount of food expired and use of the appliance (number of times when the door is opened, temperature, etc.). This information is useful to supervise for example the correct diet of the user and also detect changes in user behavior and habits. Furthermore, the remote monitoring unit may warn when something unusual happens; for example if the user has not opened the refrigerator in one day (when supposed to be at home) she/he might have a problem.
  • the product sensor for detecting the product parameter may be realized as a RFID-sensor unit which may include a RFID UHF reader.
  • the RFID UHF reader controls a RFID UHF 4-way multiplexer that multiplexes in time the RFID UHF antennae.

  • the multiplexer may be directly attached to each of said antennae with special HF cables. It may trigger each antenna at a defined interval which can be tuned according to the refrigerator used.
  • the impedance will be between 45 to 55 Ohms, preferably 50 Ohms.
  • the antennae setup within the refrigerator is of relevance. It may be of an advantage if the RFID sensors are disposed with respect to a transversal axis and/or an vertical axis symmetrically and facing each other. Such a setup is preferred in a refrigerator having a cooling compartment which has an opening at its front side.
  • the RFID-sensors may be disposed at the left and right compartment sides as well as at the ceiling and the bottom side, respectively. Said RFID-sensors may be integrated in the insulating foam which is filled into the hollow spaces of said body restraining the cooling compartment.
  • the antennas may be integrated into said insulating foam during the manufacturing process.
  • said remote monitoring unit may generate a user profile on the base of said operational and product parameters.
  • said parameters may be stored over the time in tabular form.
  • any deviation of user activities with respect to the household appliance from the user profile can be detected.
  • user behavior and habits can be monitored by e.g. an external carer who can detect any deviation from the user profile which could make it necessary for the external carer to support the user in his/her household.
  • An electronic product code (EPC) based on a SGTIN96 coding scheme should be used for coding of the RFID tags.
  • a SGTIN96 coding scheme features the following structure:
  • the header identifies the encoded data as an SGTIN-96 number.
  • the special field contains data such as a filter value for pre-selection and a partition value that indicates the point where the division between the company prefix and the item reference is.
  • the company prefix specifies the manufacturing company while the item reference identifies the object to be refrigerated. Accordingly, the item reference can be used to encode information concerning the object.
  • Information concerning the object may comprise: type of item (e.g. food), food type (e.g. vegetables, pasta, etc), and/or weight (e.g. tenths of grams up to 10 kg). Additional information may be encoded in the serial number. Additional information may comprise: need of refrigeration, product ID with regard to a provider, nutritional facts, ingredients, lot, and/or packing date.

  • the impedance will be between 45-55 Ohms, preferably 50 Ohms. Circular polarization will ensure reading tags in two dimensions rather than one, and with circular tags on the items, three-dimensional reading is possible.
  • the antenna gain should be medium, around 4-6 dbi.
  • the radiating/receiving angle should be wide between 70 and 90, preferably around 80°.

  • an external carer can get an overview of the user habits and behaviors without intervening into the housekeeping of the user personally. For example, a nutritional protocol of the user can be monitored which may be preset by a supervisor of the user. If necessary, i.e. in case of any kind of deviation from the user profile, the external carer can personally intervene so as to support the user.
  • the monitoring unit 23 also comprises operational and display elements 29, 30 by which the external carer can intervene remotely without directly actuating the operational elements 17 of said refrigerator.
