It is no longer necessary to make provision that a cleaning rod which is to dissolve at a later time, to place at a level in the cooking chamber, which is not reached in an initial cleaning step of the cleaning liquid.
  • detergent and rinse tabs can be used side-by-side without fear of the rinse-off bar dissolving too early in the cleaning process.
  • a descaling tab which has been produced at a higher pressing pressure than the rinse aid, can also be used immediately at the beginning of the cleaning process. This eliminates the need for operating personnel, depending on the process step reached the cleaning process to give a second cleaning rod, a rinse aid or a descaler into the oven. Also can be waived, containers for z. As rinse aid or decalcifier to be installed at a higher level in the oven have to be absorbed by the cleaning fluid only at higher filling. In this way it is possible to subject the entire cooking chamber already during the first cleaning cycle of a complete cleaning. It has also proven to be particularly advantageous to use multiphase tablets in which the individual phase components have been produced at different pressing pressures.
  • such Mehrphasentabs have been found to be very suitable, in which the individual phases are arranged in Spähr umfact.
  • a descaling ball may be present inside a multiphase bar, which is surrounded concentrically by a layer of rinse aid, which in turn is concentrically surrounded by one or more detergent layers.
  • the inner descaler phase has been produced at a higher pressure than the final rinse phase and the final rinse phase at a lower pressure than the cleaning phase.
  • the timing of the dissolution of the individual phases of a cleaning process can be adjusted specifically.
  • a color can be assigned to each individual cleaning process, with which the multi-phase cleaning rod and / or its packaging is then made recognizable, so that a reliable and error-free handling is ensured. Furthermore, it is of course possible to separate the individual phases of a multiphase tablet by one or more films to achieve the effect described above.
  • the cleaning agent of FIG. 1 is a spherical cleaning rod 1, which includes a rinse aid 2, a film 3, a cleaner 4 and a further film 5 from the inside to the outside.
  • the various components 2, 3, 4 and 5 of the cleaning rod 1 are arranged concentrically around each other.
  • the dissolution behavior can also be influenced by the fact that the cleaner 4 has been produced at a lower pressing pressure than the rinse aid, which is not apparent from the drawing.
  • the film 5 is released under certain conditions, for example at a certain temperature, so that the cleaner 4 can then exert its effect. After the cleaner 4 has been used up, the film 3 dissolves after a certain period of time, so that finally the rinse aid 2 can exert its effect.
  • FIG. 2 shows a spherical Mehrphasentab, in which the inner rinse aid 2 has been prepared at a higher pressure than the pressure of the external cleaner 4.
  • the phase components 2 and 4 are not separated by a film. This allows an even better and cleaner subdivision of the individual phases of action. In particular, it no longer occurs that, when the cleaner 4 is almost completely dissolved, rinse aid already dissolves at the same time and is used in the cleaning step.
  • a tab according to FIG. 2 Now, a very clean separation between the cleaning step and the rinse step is achieved because the rinse aid begins to dissolve only when the cleaning step is completed and the cleaning waste water has been removed from the interior. In this way, the rinse effect is further improved.
  • the aforementioned effects are also observed in a corresponding manner, if in the interior of the spherical Tabs a descaling phase is provided, which has been prepared at a higher pressure than the rinse-rinse.
  • FIG. 3 also shown cleaning agent is a spherical cleaning rod 10 which is arranged in a bag 11.
  • the cleaning rod 10 in turn comprises, from the inside to the outside, a decalcifier 12, a rinse aid 13, a first cleaner 14 and a second cleaner 15, wherein the various components 11, 12, 13, 14 and 15 are arranged concentrically with each other.
  • the Purifier, rinse aid and descaling phases have been prepared at different pressures, which is the FIG. 3 not immediately apparent, wherein the respective inner phase has been produced at a higher pressure than the adjacent outer phase.
  • the bag 11 for example, in a wash liquor reservoir of a cooking appliance, not shown, from which a wash liquor is pumped into a cooking chamber and into which a wash liquor flows from the oven, wrapped, so the bag dissolves 11 after a predetermined period of time, so that then the second cleaner 15 can exert its effect, for example, to reduce fats.
  • the first cleaner 14 may begin to solve the other soiling in the oven. After consumption of the first cleaner 14 may then come using the rinse aid 13 to a rinsing process. If the rinse aid 13 is also consumed, descaling of the cooking appliance is finally carried out by means of the descaling device 12.
  • the multiphase cleaning bar 1 and 10 it is possible in a simple manner, without additional liquid reservoirs and without interrupting a cleaning process to undergo certain cleaning procedures, fully automated. Different cleaning methods may have been used for different cleaning methods, so that a precise adjustment can be made here.
  • the cleaning process can, for. B. be selected depending on the degree of contamination together with associated cleaning rod.
  • FIG. 4 schematically a cooking appliance 16 with an accelerator 17, a pipe 18 and an impact surface 19 is shown.
  • the acceleration device 17 comprises an actuating handle 20 and a spring 21 and a cylindrical punch 22 which in the ground state both closes the accelerating device with respect to the cooking chamber of the cooking appliance 16 and also causes the tabs 23 located in the storage container 24 to not enter the tube 18 , Only by moving the punch 22 against the spring force tab 23 is released and can be accelerated from its rest position by simply releasing the handle 20 against the impact surface 19.
  • the impact surface 19 is preferably patterned as shown, thereby assisting the mechanical crushing of the impacting tabs.
  • the individual parts of the tabs can then, for. B. via a nozzle or a water outlet, sprayed or illuminated.
  • the storage container 24 can be configured in a transparent manner, so that the desired cleaning sequence can be made clear by the use of correspondingly color-coded cleaning bar, so that it can be seen from the outside at any time during the cleaning process which cleaning stage is present.
  • the described addition mode can also be automated.
