Abstract

A system of domestic appliances is provided, wherein the domestic appliances are operated from a branch of an, in particular public, supply system for electrical energy at a customary system frequency, wherein, in particular, the consumed energy which is supplied to the branch can be detected, and wherein a display and measurement unit is present, allowing the energy consumed by an individual domestic appliance to be displayed and measured. In this case, the functioning thereof for determining the consumption of the individual domestic appliance is based on the analysis of a characteristic structure, which can be assigned to the individual domestic appliance, of current and/or voltage profiles within system period time intervals during operation of the individual domestic appliance, wherein, for individual domestic appliances of which the inherent characteristic structure is small, the characteristic structure can be formed or added to by a structure generator.

First claim

The invention claimed is:

1. A system of domestic appliances, wherein the domestic appliances are operated on a branch of an, in particular public, supply network for electrical energy at a standard network frequency, wherein in particular the consumed energy supplied to the branch can be detected, the system comprising:
a display and measuring unit that allows the display and measurement of the consumed energy of an individual domestic appliance, wherein:
its function of determining the consumption of the individual domestic appliance is based on the analysis of a characteristic structure of current and voltage profiles that can be assigned to the individual domestic appliance within network period time segments during operation of the individual domestic appliance;
the characteristic structure of individual domestic appliances whose own characteristic structure is small can be formed or added to by a structure generator; and
the characteristic structure including harmonics and their amplitude size for current and voltage profiles of an operating domestic appliance.

2. The system as claimed in claim 1 , characterized in that the display and measuring unit is configured within a device provide specifically for the purpose.

3. The system as claimed in claim 1 , characterized in that the display and measuring unit is configured within a master domestic appliance.

4. The system as claimed in claim 1 , characterized in that the display and measuring unit (AM) has a visualization part, which comprises display regions for the energy consumption of the individual domestic appliances and preferably also all the domestic appliances in the system of domestic appliances.

5. The system as claimed in claim 4 , characterized in that the visualization part is assigned to the operating panel of the master domestic appliance.

6. The system as claimed in claim 1 , characterized in that a signal corresponding to the characteristic structure of current or voltage profiles within network period time segments or from structure generators is converted to digital by means of an analog/digital converter and can be used in an analyzer in respect of a stored comparison range by means of an identification unit for assigning the consumed energy of the associated domestic appliance.

7. The system as claimed in claim 6 , characterized in that the comparison range for the analyzer can be obtained by initialization procedures of the domestic appliance system and stored preferably in an internal storage unit of the display and measuring unit.

8. The system as claimed in claim 6 , characterized in that the comparison range for the analyzer can be stored and accessed in an external storage unit, which has a data line to the display and measuring unit, it being possible for said comparison range preferably to be supplied by a manufacturer of the relevant domestic appliance.

9. The system as claimed in claim 1 , characterized in that the display and measuring unit (AM) has a visualization part, which also selectively comprises a display means, as triggered by way of rotary switches, which displays the power required instantaneously for an individual domestic appliance, it being possible also for said value to be stored in particular on an external storage unit, so that a manufacturer or service company can have access thereto.

10. The system as claimed in claim 1 , characterized in that an assembly kit is supplied, in order to be able to configure the system in a preferred manner in respect of a household.
