Definitions
- the invention relates to an arrangement for cleaning a Oven according to the preamble of claim 1.
- This catalytic self cleaning is with a number of Disadvantages connected.
- the catalytic requires Self-cleaning, as already mentioned, a relatively high temperature. This temperature should be chosen so that on the one hand the desired cleaning effect can be achieved, that on the other hand also damage or a gradual Destruction of the interior of the oven is avoided.
- Catalytic self-cleaning requires a high level Use of energy and is also associated with the further disadvantage that the oven is cleaning during a cannot be used for a relatively long time. This time is composed of the time in which the operating temperature is formed from the time of the actual Cleaning and finally out of the time required is to cool the oven back down to a temperature which allows safe operation of the oven.
- a device and a method is known from German published patent application DE-A-28 42 771 known for the heat treatment of foods, in particular for the preparation of dishes, for cleaning the oven with a muffle the oven has a container Includes a liquid detergent, which if necessary from the container is removable. The detergent removed as required is sprayed through a mechanism sprayed into the muffle room of the oven.
- the invention is based on this prior art the task based on an arrangement of the aforementioned Specify the self-cleaning of ovens simplified.
- the arrangement according to the invention is characterized by the advantage that the cleaning agent is stored in the oven itself and thus for cleaning processes is available.
- the detergent leaves automatically lead into the area of the oven muffle bottom, so there is no need for manual feeding.
- the detergent dissolves contaminants even at room temperature. However, it can also be heated so that it is the cleaning time is reduced.
- the cleaning agent be warmed to its evaporation so that it too reached the side walls of the muffle and the ceiling and there also removes impurities.
- the oven and in particular the muffle is by this temperature, which is far below the maximum operating temperature, for example for certain baking and roasting processes is not impaired.
- Corresponding to the comparatively low temperature cleaning takes only a short time, so that the oven is long enough lets you use it as intended.
- Another particular advantage of the arrangement according to the invention consists in the only necessary for cleaning low energy consumption. This applies in particular to embodiments of the invention in which the detergent is heated by the residual heat (approx. 70 - 120 ° C).
- the Muffle M is cuboid. In their floor area a depression, in particular a tub W, is arranged, the inclusion of a cleaning agent R, such as a soapy water or an enamel cleaner. Muffle M or trough W can be formed in one piece, alternatively a separate tub W is provided.
- a dosing container B is arranged above the muffle M, that contains the detergent.
- the dosing container B is via a solenoid valve MV with a connecting line VL connected, which leads into the tub W.
- MV solenoid valve
- VL connecting line
- a residual heat sensor RWF is arranged via a signal line and possibly a switch with the solenoid valve connected is.
- the switch When the switch is closed signals given by the residual heat sensor RWF to the solenoid valve MV fed. If the RWF residual heat sensor detects temperatures, for example in the range of 70 - 120 ° C, it forms signals, which open the solenoid valve MV. So that the drain is a Predeterminable amount of the cleaning agent R from the container B Approved. It flows through the connecting line VL into the Trough W, where it is heated and evaporated by the residual heat becomes. The contaminants on the bottom of the tub become one chemically dissolved. On the other hand there are burned-in residues based on the temperature difference between the muffle bottom and Detergent released.
- the cleaning process can, provided there is no switch with a residual heat sensor and solenoid valve is provided, or this is closed automatically by means of an appropriate control after every baking operation.
- a signal lamp SL which is controlled by the RWF residual heat sensor, indicates the cleaning process.
- a detergent solution for example, is used as the cleaning agent R. or an enamel cleaner.
- the evaporated cleaning agent dissolves impurities on the Muffle M from the side walls and on the ceiling. Any, still remaining impurities are relatively easy to manually remove.
- the cleaning agent fed into the tub is after being fed the residual heat from a heater of the oven, in particular can be reheated by the bottom heat radiator.
