Definitions

• the invention relates to household appliances that have an electronic Have controls for controlling the operation, and optionally in a standard operation with unrestricted Function or in a restricted exhibition, in which one or more functions of the Household appliance are switched off or restricted, operable are.
• the presentation of household appliances, especially electrical appliances, for sales purposes, for example at trade fairs or in specialist showrooms usually an unattended installation of the devices.
• the equipment be reduced Scope can be operated so that the prospective buyers a picture of how the device works and can do its operation as well as the operation who can try out the device functions. It should however to avoid unnecessary energy consumption and especially to prevent damage to the device and guaranteed by injuries to prospective buyers be that certain functions are not actually triggered even if the corresponding activation is on the device.
• a disadvantage of this known, hardware or circuit technology realized solution is that changing the electrical wiring the use of a specialist required so that the entire associated with the retrofit Time expenditure, even if the conversion itself by a corresponding design of the household appliance itself relatively can be done quickly, a not inconsiderable effort represents.
• Another disadvantage is that when Selling a home appliance that is in the circuit for one Exhibition was set up, be forgotten can, the electrical wiring again for standard operation to change, for example by inserting the required bridge. Of course, this leads to complications and additional effort during commissioning by the buyer who malfunctioned the home appliance notes.
• the present invention takes this state into account the technology based on the task of a household appliance to further train that it is inexpensive from the exhibition in standard operation and preferably also vice versa can be moved.
• the change of Operating mode not carried out by unauthorized persons can and the home appliance as much as possible against accidental or accidental switching, especially in standard operation.
• the inventive solution to this problem in one Home appliance that has an electronic control system for controlling of the company and optionally in a standard company with full functionality or in one restricted exhibition, in which one or several functions of the household appliance switched off or restricted are, is operable is that the electronic control for optional switching of the operating mode from exhibition to standard operation is trained and a time control device has, which is designed such that the optional Switching within a specified release period feasible after a given event and after Expiry of this release period until the next entry of the event is prevented.
• the electronic control is used to select the operating mode of the exhibition to switch to standard operation. Switching is done, for example, by entering a specific one Codes or passwords or a specific function selection, for example with a key or a key combination. In this way, for example, the exhibition business activated by input and by another Input can be switched back to standard operation.
• the electronic control of the household appliance has a time control device that such is designed that the optional switching within a predetermined release period after a predetermined Event feasible and after this release period until the next occurrence of the event is prevented. Due to a time limitation of the switchover option between exhibition and standard operation after a given event, the probability for an accidental or the possibility of one deliberate switching restricted so that none or lower requirements regarding password protection for switching the operating mode are.
• the operating mode can be provided using a key or a key combination switch. If this actuation after the expiry of the release period after the given event the operating mode is not changed.
• a first advantageous embodiment can consist in that the given event is a particular actuation of the household appliance, in particular a specific function selection or entering a specific code or Password is.
• the operating mode can only be changed if the Home appliance clock set to a specific time of day is when a certain oven temperature is set is selected or another special function and then the operating mode within the release period by the key provided, key combination or input is switched.
• a second, preferred embodiment consists of that the given event is the application of the supply voltage to the household appliance.
• This offers a maximum Protection against accidental, accidental or willful Switchover of one exhibited in the exhibition Device in standard operation, since creating the supply voltage, i.e. for example connecting of the household appliance to the network, usually not or not easily from a prospective buyer or Users can be done immediately, so that a commissioned device after the expiry of the release period remains in the set operating mode.
• the supply voltage must be changed to change the operating mode be switched off first, for example by pulling the power plug, loosen the connection terminals, switch off the mains voltage or switching off the mains fuse. At the Reinstalling the supply voltage must then be within the release time on the device the operating mode because after the expiry of the release period the electronic control switching prevented again.
• Some household appliances have a so-called main switch with which the entire device or essential functions of the device can be switched off.
• a main switch With ovens for example, it is known such a main switch provide with which all oven functions and, if necessary those of a connected hob turned off. However, the device will continue to do so powered because, for example, the operation a built-in clock is maintained.
• the predetermined Event that gives the opportunity to change the operating mode opened within the release period, not the Actuation of such a main switch is because in In this case, there is no very high security against unauthorized persons Switching is given. Rather, it is preferred if the electronic control as a predetermined event Applying the supply voltage itself to the household appliance evaluates.
• the release period between two seconds and 15 minutes, preferred is between ten seconds and five minutes.
• an advantageous feature can be that the electronic control has a storage device, which is designed such that after a failure or switching off the supply voltage of the previously set one Operating mode is resumed when the Supply voltage again applied to the household appliance becomes.
• the set operating mode can, for example in a permanent memory, e.g. stored in an EEPROM and even after a long interruption in the supply voltage, e.g. on weekends or during company holidays can be read out again by the electronic control.
• the deactivation of home appliances according to the invention i.e. ensuring that it remains in the exhibition also with manipulations, demonstrations and operations of the household appliance, is in principle for all household appliances can be used advantageously.
• Home appliances of interest that are either relatively high Have electricity requirements or a certain potential hazard represent.
• processing equipment of foods such as blenders, mixers, Cutting and other size reduction devices, devices for preparing dishes such as cookers, ovens, steamers, Steam ovens, microwave ovens, etc., appliances for Treating laundry such as washing machines, tumble dryers, Ironing machines and irons, devices for storing Food such as refrigerators or freezers or devices for cleaning of dishes such as dishwashers.
• the invention can refer to functional restrictions that one Use of electricity, gas, water, air, compressed air or one require different fuel.
