Definitions

  • the invention relates to a system comprising a household appliance having an appliance housing, a battery having a battery housing and an optical display device integrated therein, and a display control device for controlling the display of information on the display device of the battery, the household appliance having a detection device for determining non- device statuses of the household appliance relating to the accumulator, the detection device being set up to transmit the detected device status of the household appliance to the display control device, the display control device being set up to control the display device of the accumulator to display the received device status of the household appliance.
  • Household appliances of the aforementioned type are known in the prior art. These can be, for example, tillage equipment, kitchen appliances, tools or the like. It is known to use an accumulator which can be connected in particular to the household appliance in a detachable manner and which has an optical display device, for example a display, for displaying information.

  • the accumulator has an optical display device on which device parameters of the household appliance can be displayed.
  • the visual display device of the accumulator can be controlled by the display control device of the system in such a way that the device statuses of the household appliance that do not relate to the accumulator itself are displayed on the optical display device of the accumulator.
  • the information about the device states of the household appliance is transmitted from the household appliance to the display control device via a communication interface and then used for control commands that cause the information to be displayed on the optical display device of the accumulator.
  • the outer surface of the housing of the household appliance which is basically only available to a limited extent, can be used optimally, namely because the optical display device of the battery not only shows the battery's own statuses, but also device statuses of the household appliance that do not affect the battery itself at all.
  • the additional accommodation of a further display device for displaying device parameters of the household appliance can be dispensed with.
  • the total space required for optical display devices on the device housing is reduced and thus also the costs incurred, especially since, for example, the same components of the system can be used for several tasks, for example housing parts, brackets, electric cables and others.

  • the display control device may also be possible for the display control device to process and/or output all known device statuses and possibly also battery statuses for display on the visual display device and then only those are actually displayed on the visual display device of the rechargeable battery for which the actual possibilities for an advertisement are created. If the optical display device does not have any colored display elements or display elements, for example, a relevant command that contains color information cannot be implemented, so that corresponding information is not displayed at all or is transformed into information that is not displayed in color, for example.
