The control system automatically records, within the non volatile memory means (MNV), information of a first type that is indicative of the temporal trend of the status variables during successive predefined reference periods, with the last stored information of the first type causing the elimination of the oldest such information, i.e. with a backward shifting operation of the stored information of the first type. The control system further allows the stored information of the first type to be read outside of the electric user. ## Claims ### Claim 1 Household electric appliance, including an electronic control system comprising: a) an electronic microcontroller; b) program memory means, containing data which allow the control system to perform a certain number of basic programs of the appliance; c) means for sensing the operating conditions of the appliance and for generating variables which relate to the status of the appliance, where the variables relate to internal events, external events, user-selected functions, and measurements of the appliance; d) read and write nonvolatile memory means; e) means for automatically storing, within said nonvolatile memory means, detailed historical information indicative of said status variables during the last operation period of the appliance, the last stored information causing the elimination of the oldest ones; and f) communication means for making the stored information available from outside the appliance. ### Claim 2 (depends on 1) The appliance according to claim 1, wherein said historical information are associated with the occurrence of internal events to the appliance. ### Claim 3 (depends on 2) The appliance according to claim 2, wherein the internal events are faults and malfunctioning of the components of the appliance. ### Claim 4 (depends on 1) The appliance according to claim 1, wherein said historical information are associated with the occurrence of external events to the appliance. ### Claim 5 (depends on 4) The appliance according to claim 4, wherein the external event is a power supply blackout. ### Claim 6 (depends on 1) The appliance according to claim 1, wherein the appliance has continuous operation. ### Claim 7 (depends on 6) The appliance according to claim 6, wherein the continuous operation appliance is a refrigerator, a freezer, or a boiler. ### Claim 8 (depends on 6) The appliance according to claim 6, wherein said operation period is a predefined time span. ### Claim 9 (depends on 8) The appliance according to claim 8, wherein said predefined time span is a week, a day or the last twelve hours. ### Claim 10 (depends on 1) The appliance according to claim 1, wherein the appliance has discontinuous operation. ### Claim 11 (depends on 10) The appliance according to claim 10, wherein the appliance is a laundry washing machine, a cooking oven, or a dishwasher. ### Claim 12 (depends on 10) The appliance, according to claim 10, wherein said operation period is represented by a predefined number of operating cycles or programs performed by the appliance. ### Claim 13 (depends on 1) The appliance according to claim 1, wherein said historical information are made available through said communication means in a remote location, for executing a deep analysis of the appliance status. ### Claim 14 (depends on 1) The appliance according to claim 1, wherein the storing of the most recent information causes the elimination of the oldest ones through a backward shifting operation of the stored historical information. ### Claim 15 Household electric appliance, including an electronic control system comprising: a) an electronic microcontroller; b) program memory means, containing data which allow the control system to perform a certain number of basic programs of the appliance; c) means for generating variables which relate to the status of the appliances where the variables relate to internal events, external events, user-selected functions, and measurements of the appliance; d) read and write nonvolatile memory means; e) means for automatically storing, within said nonvolatile memory means, detailed historical information indicative of said status variables during the last operation period of the appliance, the last stored information causing the elimination of the oldest ones; and f) communication means for making the stored information available from outside the appliance. ### Claim 16 (depends on 15) The appliance according to claim 15, wherein said historical information are associated with the occurrence of internal events to the appliance. ### Claim 17 (depends on 16) The appliance according to claim 16, wherein the internal events are faults and malfunctioning of the components of the appliance. ### Claim 18 (depends on 15) The appliance according to claim 15, wherein said historical information are associated with the occurrence of external events to the appliance. ### Claim 19 (depends on 18) The appliance according to claim 18, wherein the external event is a power supply blackout. ### Claim 20 (depends on 15) The appliance according to claim 15, wherein the appliance has continuous operation. ### Claim 21 (depends on 20) The appliance according to claim 20, wherein the continuous operation appliance is a refrigerator, a freezer, or a boiler. ### Claim 22 (depends on 20) The appliance according to claim 20, wherein said operation period is a predefined time span. ### Claim 23 (depends on 22) The appliance according to claim 22, wherein said predefined time span is a week, a day or the last twelve hours. ### Claim 24 (depends on 15) The appliance according to claim 15, wherein the appliance has discontinuous operation. ### Claim 25 (depends on 24) The appliance according to claim 24, wherein the appliance is a laundry washing machine, a cooking oven, or a dishwasher. ### Claim 26 (depends on 24) The appliance, according to claim 24, wherein said operation period is represented by a predefined number of operating cycles or programs performed by the appliance. ### Claim 27 (depends on 15) The appliance according to claim 15, wherein said historical information are made available through said communication means in a remote location, for executing a deep analysis of the appliance status. ### Claim 28 (depends on 15) The appliance according to claim 15, wherein the storing of the most recent information causes the elimination of the oldest ones through a backward shifting operation of the stored historical information.
