Definitions

  • the invention relates to a method for controlling an electric cooking appliance with a heating device and a timer module as well as a timer module designed to carry out this method.
  • a timer for a household appliance for setting a time-controlled operation, for example a hob. It can be protected against unauthorized use after activating a parental control household appliance, with activated parental control only one time, a process duration or an operating period are adjustable.
  • the invention has for its object to provide an aforementioned method and a suitable method for performing this method timer assembly with which problems of the prior art can be achieved and in particular advantageously a fuse-lock function on an electric cooking appliance provided with a heater, can be activated and canceled.
  • the electric cooking appliance which is particularly advantageous an oven, a timer unit with a timer relay and a switch for mode selection and a switch for setting a heating temperature or a heating power.
  • the timer relay is serially connected in a power supply line to the heater of the electric cooking appliance.
  • a timer setting is blocked against change by a special operating function, which will be discussed in more detail below. This means that a predetermined in the timer assembly of a user by the respective timer setting expiration of the electric cooking appliance as provided, ie, for example, starts after a predetermined time and stops after a predetermined time again.
  • the heater or possibly even the entire electric cooker is turned off by opening the timer relay, so that then a total operation of the heater or the electric cooking appliance is no longer possible.
  • the timer relay must first be closed again, which is only possible by another or the same special control function on the timer module.
  • this first backup disable function is a type of lock for the timer assembly itself. According to a second aspect, it causes one after the end of the process Locking or deactivating the heating device or the electric cooking appliance is mandatory. For this purpose, the timer relay is opened, which can not be opened by the locked timer module, unless the timer has been activated by another special operating function. Building unit is unlocked, so to speak.
  • a second basic embodiment of the method in which, unlike the first, no timer setting has been made or no sequence of the electric cooking device has been specified, is after activation of a second fuse-locking function on the timer assembly by a special operating function opens the timer relay immediately.
  • a second fuse-locking function on the timer assembly by a special operating function opens the timer relay immediately.
  • the timer relay can only be activated again by another special operating function on the timer module or can be closed.
  • This second basic embodiment of the invention thus covers the case that just nothing has been set to the timer unit. If the timer module is then locked so to speak, not only it itself can not be changed, but it takes place as it were equal to a blocking or deactivation of the heater or the electric cooking appliance.
  • the timer relay that has to be closed or activated again in that the fuse blocking function is canceled or deactivated.
  • This can, as it is known in principle from the prior art, be achieved by various operating functions, including the simultaneous operation of multiple controls, sequential operation of multiple controls in exactly prescribed order or a long-lasting operation of at least one control element is to be understood. After re-closing the timer relay, the electric cooker can be operated again in any mode.
  • the first and the second safety lock function can be activated at the same time by the same activation or by the same special operating function on the timer module. Whether then the first or the second backup lock function is activated, depends exclusively on whether a timer operation has already been specified or not. This means that after the special operating function, the first safety lock function is activated when a timer operation is specified. Otherwise, the second safety lock function is activated, ie the heater or the electric cooker completely blocked.
  • the first fuse blocking action advantageously ensures only a time function set in the timer module against alteration or adjustment. This means that only the timer mode runs as set and can not be changed.
  • the second fuse-locking function then secures just advantageous in the case that in the timer unit still nothing is set, the heater or the entire electric cooker against switching.
  • a fuse-lock function it is possible to display on the timer module or the electric cooking appliance when a fuse-lock function is activated. It may even be possible to indicate which of two different backup lock features is enabled. This distinction can also be omitted, for example, if just a type of backup icon is displayed. For example, a display may be provided with a corresponding recognizable symbol for a display. Although this display can also be generally provided on the electric cooking appliance. However, it is considered advantageous if provided on the timer assembly. Even then, this can be designed as an independently manageable unit that has all implemented in her or caused by them functions themselves or executes.
  • the safety lock function is automatically activated as a child safety lock or lock when the electric cooker is connected to a power supply for the first time. Furthermore, it can be provided that, for example, in the case of a power failure, the safety lock function, preferably then just the second safety lock function, is activated so as to achieve a kind of parental control. This can be prevented that is deactivated by the power failure with normally activated fuse-lock function or deleted and the electric cooker would be unsecured.
  • the method is particularly suitable for operating a baking oven as an electric cooking appliance.
  • a baking oven may have a pyrolysis function to clean an oven muffle by very strong heating with an oven heater as a heater.
  • the timer module may have a locking relay, which for the Duration of pyrolysis operation locks a door lock on the oven muffle, so that the oven muffle can not be opened.
  • the timer module thus has both the timer relay and the said locking relay.
  • the timer module is provided with a further input for a temperature sensor which is arranged in the oven muffle.
  • This temperature sensor allows through this input the deactivation of the door lock, which locks, for example, for a prescribed pyrolysis at very high temperatures by means of the locking relay, in the event that the temperature in the oven muffle again falls below a critical for the opening to be considered temperature ,
  • the oven muffle can only be opened by an operator when no risk of burns is given.
  • the timer assembly according to the invention is characterized in that it is an independently manageable unit and has its own controls. This timer assembly can also be connected later in an electric cooker or installed. Thus, a retrofitting is possible under certain circumstances, in which just the timer relay is looped into the power Zuieitung to the heater or to the electric cooker in total.
  • the timer module may still have a timer display, for example, one or more seven-segment displays.
  • the controls can be advantageous touch switch. Particularly capacitive touch switches are available.
  • the timer module is particularly advantageous also formed separately from a control or separate from mode selector switches and planteseinousschaltem the electric cooking appliance. It makes sense to have them in their own To arrange housing, which then has just said functional units.
  • a timer assembly 11 according to the invention is shown, both in terms of their function in Fig. 1 as well as their construction in the Fig. 2 and 3 ,
  • the timer module has a housing 12, advantageously Plastic and with an upper transparent window, in which a circuit board 13 is used with various components.
  • Fig. 1 shows that the timer module 11 is connected to its own power connector 15, in particular for its own timer controller 28, and on the other hand connected to a power supply line 16 and is looped into the power supply line 16.
  • the timer assembly 11 is then in the installed state part of an electric cooking device 18, which is particularly advantageous an oven with several heaters 19, which may be formed as different oven heaters.
  • the timer module 11 is looped into the power supply line 16 from a power controller 22, which is advantageously designed as a clocking power controller, to the heaters 19 out.
  • Which of the heaters 19 are supplied with power via the power supply line 16 can be adjusted via a heating selector switch 20, advantageously similar to the power controller 22 is provided with a rotary knob 23 and is arranged easily accessible to the electric cooking appliance 18 at a panel , Thus, the power controller 22 determines the amount of electrical power to the heaters 19. The heating selector switch 20 determines which of the heaters 19 are supplied with this power
  • the timer module 11 has a timer relay 25 with a relay switch 26, which are controlled by a timer controller 28. It can be seen how, according to the invention, the timer relay 25 is looped into the power supply line 16 so that the relay switch 26 can open the power supply line 16. This will be discussed in more detail below. Furthermore, the timer module 11 has a power supply 29 and operating elements 30.
  • the timer assembly 11 may include a latching relay 35 having a relay switch 36 which is also externally accessible Connections, as well as a temperature sensor connection 37.
  • a temperature sensor arranged in an oven muffle can be connected and the temperature signal given to the timer control 28.
  • Said display 32 of the timer module is advantageously formed as a multi-function display with seven-segment display and various symbols, including the lock icon 33.
  • the housing 12 still housing openings 31, in which the cylindrical controls 30th , which are referred to as so-called touch sensor elements according to the EP 859 467 A1 are formed, can be used. Then, the entire timer assembly 11 can be mounted on the back of an oven screen, not shown, so that the controls 30 abut with their protruding from the housing 12 end face of the panel and the display 22 through the aperture is easy to see.
  • the function of the timer unit 91 with the timer relay 25 is as follows. Usually, the timer relay 25 is closed with relay switch 26, so that operation of the electric cooking appliance by means of power controller 22 and heating selector switch 20 can be done directly. If now according to the above-mentioned first basic embodiment of the invention, a timer setting and then locked against changing, so the programming of the timer assembly 11 is first made with certain on-time and off, which is possible via the controls 30. Upon completion of the timer setting, by, for example, operating one of the controls 30 for 5 seconds, the security lock function on the timer unit may be activated and locked.
  • the timer relay 25 including relay switch 26 closes and the preset operation of the electric cooking appliance expires. If the set time has expired, open timer relay 25 and relay switch 26 again and the electric cooker is stopped again. Even if changes are made before the timer operation, during the timer operation or after the timer operation on the heating selector switch 20 and the power controller 22, this does not change the predetermined timing, although of course a power by means of the power controller 22 unintentionally high could be adjusted.
  • the same control element as mentioned above is operated for 5 seconds, which causes an opening of the timer relay 25 with relay switch 26 and thus prevents operation of the heaters 19. Any settings on the heating selector switch 20 and the power controller 22 can not change this. This is a kind of duration lock.
  • a temperature sensor of the oven muffle is connected to the temperature sensor connection 37. If the pyrolysis function is recognized by or in consequence of the very high temperature detected in the oven muffle via the temperature sensor, the latching relay 35 with relay switch 36 can, at a critical temperature of, for example, 250 ° C., not shown in more detail but readily known, door lock the oven door so activate that the oven door can not be opened. Only when, after the end of the pyrolysis process, the timer controller 28 via the temperature sensor port 37 reports the drop in temperature below the critical temperature as detected, locking relay 35 and relay switch 36 are opened, so that then the oven door can be opened again ,
  • a timer assembly is created, which via a built-timer relay 25, possibly also the locking relay described, and programmed into a timer control 28 backup lock function either the own timer setting or, if such has not been entered, the entire electric cooker or its heaters can lock against misalignment or unauthorized activation. Even if this does not rule out any error, at least a significantly higher level of security is achieved.
