  • the control unit may detect laundry introduced into said washing machine or removed from said washing machine.
  • the control unit may check the compatibility of the laundry introduced with a selected washing program. In case of incompatibility said control unit may generate a warning signal.
  • the control unit may suggest and/or configure a washing program on the base of the laundry introduced into the washing machine. In case the control unit detects a bad mixture of laundry (e.g. clothes with different colours) it may generate a warning signal for the user.
  • the household appliance can be embodied as a cooking device, especially as a microwave oven whose control unit may detect food introduced into said microwave oven. On the base of said food introduced, the control unit may suggest a suitable cooking program to the user. While conducting the cooking program, the control unit may display the present operational status, e.g. the time to end.
  • a refrigerator comprising a cooling compartment 1 is shown which is enclosed by an appliance body 3 as well as an appliance door 5.
  • the hollow spaces of said body 3 and said door 5 are filled with a heat insulating foam 7.
  • an evaporator 9 is disposed which is integrated in a refrigeration cycle 10 in order to cool the cooling compartment 1.
  • the actual temperature of the cooling department is detected by a temperature sensor 8 and passed to the control unit 11.
  • the control unit 11 compares said actual temperature of the cooling compartment 1 with a preset temperature which is set by the user. On the base of this comparison the control unit 11 switches a compressor 15 integrated within the refrigeration cycle 10 on or off.
  • the control unit 11 is linked with a control panel 19 which carries operational and/or display elements 17, 18.
  • the control unit 11 is in wireless communication 21 with a monitoring unit 23 which is located remotely from the refrigerator.
  • a monitoring unit 23 which is located remotely from the refrigerator.
  • a user profile 25 can be generated which is shown in figure 2 .
  • an external carer can be provided with statistical information about the actual inventory inside the cooling compartment 1, about the dwell time of the food A and B inside the cooling compartment 1, about food with lapsed expiry dates as well as about a malfunction of the refrigerator.
  • control unit 11 comprises RFID readers 27 or RFID antennae which are integrated in the heat insulating foam 7.
  • RFID readers 27 or RFID antennae which are integrated in the heat insulating foam 7.
  • said food A, B inside the refrigerator needs a RFID tag with their respective information.
  • the control unit 11 may detect various operational parameters of the refrigerator as well as product parameters of the food A, B introduced into the cooling compartment 1.
  • product parameters S 1 to S 6 are, just as an example, listed in the user profile 25 shown in figure 2 .
  • the product parameters S 1 to S 3 refer to food A
  • the product parameters S 4 to S 6 refer to food B.
  • the product parameters S 1 and S 4 of food A and B refer to information about whether the expiry date is exceeded or not.
  • the product parameters S 2 and S 5 refer to information about whether the amount of food A or the amount of food B is more than a preset limit.
  • the product parameters S 3 and S 6 refer to information about whether the actual dwell time of food A or food B inside the cooling compartment 1 of the refrigerator is more than a preset time.
  • control unit 11 In addition to the product parameters S 1 to S 6 the control unit 11 also detects operational parameters S 7 and S 8 which refer to information about the operation of the refrigerator.
  • the operational parameter S 7 refers to information about whether the door opening time is more than a preset time (in this case two minutes).
  • the operational parameter S 8 refers to information about whether the temperature detected by the temperature sensor 8 inside the cooling compartment 1 is in a regular range between 2°C and 5°C.
  • All of the product parameters and operational parameters S 1 to S 8 are analyzed in the control unit 11 which may generate an optical warning signal in the display element 18 of the control panel 19 in case of a malfunction or in case of a misoperation of the refrigerator.
  • the monitoring unit 23 generates said user profile 25 already mentioned above on the base of the transmitted product and operational parameters S 1 to S 8 .
  • the operational and product parameters S 1 to S 8 are listed over the time.
  • 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 25, the external carer can personally intervene so as to support the user.
  • control unit 25 also comprises operational and display elements 29, 30 by which the external carer can intervene remotely without actuating the operational elements 17 of said refrigerator. Moreover, the external carer can also get information about the actual state of operation of the refrigerator via the display element 30 of the monitoring unit 23.
  • the monitoring unit 23 may also be in wireless communication 21 with a microwave oven 31 as is shown in the second embodiment of figure 3 .
  • the control unit 11 of the microwave oven 31 is similarly to the first embodiment equipped with RFID readers 27 which detect food introduced. On the base of the detected food the control unit 11 may suggest a suitable cooking program to the user via the display element 18 of the microwave oven. Additionally, the control unit 11 can indicate the actual operation status while carrying out the cooking program, e.g. the time to end.
  • control unit 25 is in wireless communication 21 with a washing machine 33.
  • control unit 11 can detect laundry which is introduced into the washing machine 33 as well as removed therefrom.
  • the control unit 11 may also check the compatibility of the laundry introduced with a selected washing program before the start of the washing program. In case of incompatibility the control unit 11 can generate a warning signal.
  • control unit 11 may further suggest and/or configure a washing program on the base of the laundry introduced into the washing machine in order to avoid any maloperation of the user. If the control unit 11 detects laundry which is incompatible a warning signal may be generated.
