Description

Field of the invention

The invention relates to a cleaning device and a method for cleaning a lying in the interior of a crucible and closed by a lid and provided with a drain cooking chamber from the cooking appliance, wherein the cleaning device is removable.

Background of the invention

Such a generic device is in the WO 2012/175564 described. The immovable positioned to the wall of the crucible demountable lance of the device in which the drive of the cleaning head and the cleaning liquid line are coupled to the crucible wall. The design of the Ankoppelungsstelle is complicated and represents in the case of leakage of cleaning liquid supply a risk to the positioned under this Ankoppelungsstelle components. Another disadvantage is the radiation-shadow space, which is located in the region of the Ankoppelungsstelle and the is not wetted sufficiently intense by the emerging from the cleaning head liquid.

In the EP 1297907 a cleaning device is shown, the supply line is located in the cooking chamber final lid. The cleaning device is removable, which means that only with the lid open the manipulation with the cleaning device is possible. The staff must install the device over the entire depth of the device, or install it unsafe with the lid partially open. After the cleaning has been completed, the remaining cleaning liquid is contained in the supply line, which releases the minerals due to the heat generated during cooking, which causes the supply line to become clogged. In the event of leakage of the coupling point dripping the residual cleaning liquid on the food, which leads to the destruction of this.

Object of the invention

The present invention is therefore based on the object, a device of the type described above in such a way that the wetting of the crucible inner surface is improved, the assembly is easier and the cost is lower and caused by the leakage of Ankoppelungsstelle leaving the cleaning liquid no harm.

Inventive solution

The object is inventively achieved in that the supply of cleaning liquid is located in the drain pipe of the cooking chamber drain, whereby the, exiting through a leak cleaning fluid flows directly into the drain. This eliminates the complicated implementation by the crucible wall or by the crucible lid. The supply pipe also serves as a carrier of the cooking chamber stopper, which controllably opens and closes the drain. This movement is also activated during the cleaning process and serves for better wetting of the crucible wall. The cleaning device is available in two basic variants, wherein the first works with an external drive of the orbital cleaning head and the second uses only the energy of the flowing cleaning liquid for driving the cleaning head movement.

Further, as advantageous details and features of the invention will become apparent from the dependent claims and their combinations as well as from the following descriptions of preferred embodiments of the invention will be explained in more detail with reference to schematic figures. It shows:

1 a schematic drawing of the prior art

2 a schematic drawing of the separate coupling of the supply pipe and the drive

3 schematic drawing of the cleaning system with pivoting support

4 schematic drawing of the cleaning system without external drive

5 schematic drawing of the cleaning system with external drive

Detailed description of the figures

In the in the 1 to 5 shown cleaning system variants are all surrounding components such as pumps, connections, brackets, guides and the like omitted.

1 is a schematic representation of the device according to the prior art, consisting of the through the lid ( 6 ) closable cooking space ( 3 ) in the ground ( 5 ) a process ( 11 ) having. The cleaning device consisting of the carrier ( 17 ) with that of the drive shaft ( 25 ) and by the flowing cleaning liquid ( 19 ) driven cleaning head ( 20 ) and from a double clutch ( 16 ) for the cleaning fluid ( 19 ) and the drive shaft ( 25 ), which over the wall ( 4 ) to the outside of the cooking chamber ( 3 ) cleaning fluid supply ( 36 ) and external drive ( 22 ) is coupled. The plug drive ( 37 ) closes the process ( 11 ). The spatial movement of the cleaning head ( 20 ) is represented by the rotation vectors ( 33 ; 34 ), the movement of the stopper ( 13 ) through the hub vector ( 27 ). The coupling point for the double clutch ( 16 ) must be provided with a separate closure during cooking, the leakage on this spot causes damage to the components below.

2 is a schematic representation of the device according to the invention with the through the lid ( 6 ) closable cooking space ( 3 ) in which by the heating ( 7 ) heated floor ( 5 ) the process ( 11 ) is located. About the Ablaufroh ( 12 ) is the Garaum process ( 11 ) to the device outlet ( 40 ) connected. The, the expiration ( 11 ) regulated wearing plugs ( 13 ) is via the inlet pipe ( 18 ) from the plug drive ( 37 ). At the stopper ( 13 ) there is a closable coupling for the clutch ( 30 ) of the inlet pipe cleaning system ( 43 ). The cleaning fluid ( 19 ) is from the cleaning fluid supply ( 36 ) through the inlet pipe ( 18 ) and the inlet pipe cleaning system ( 43 ) to the carrier ( 17 ) and from this carrier ( 17 ) to the cleaning heads ( 20 ), from which through the nozzles ( 21 ) flows under pressure and by the reaction force the head for rotation after the vector ( 34 ) brings. In the carrier ( 17 ) is the drive shaft ( 25 ) at one end via the clutch external drive ( 23 ) from the external drive ( 22 ) is ground and the second end is to the driver ( 28 ) Of the head ( 20 ) and so it turns this to vector ( 33 ). The design of the passage area ( 41 ) is due to the sealing of only one shaft ( 25 ) easy. The inlet pipe ( 18 ) is over an easily deformable and waterproof part such as bellows ( 31 ) to the cleaning inlet ( 36 ) connected. If there is leakage in the carrier ( 17 ) to the transit area ( 41 ), the cleaning fluid ( 19 ) through the emptying tube ( 39 ) in the cooking chamber ( 3 ) and can not pressurize the transit point.

3 is a schematic representation of the device according to the invention as in the 2 with that in the transit area ( 41 ) pivotally mounted supports ( 17 ) from the inlet pipe cleaning system ( 43 ) is driven so that the carrier ( 17 ) with the cleaning head ( 20 ) in the cooking chamber ( 3 ) can move spatially.

4 is a schematic representation of the device according to the invention in a simple embodiment, in which the external drive ( 22 ) of the cleaning head ( 20 ) by the driven by the flowing cleaning liquid internal drive ( 44 ) is replaced and this internal drive ( 44 ) rotates with the head driver ( 28 ) in the rotation vector ( 33 ). The stopper drive drives via the inlet pipe ( 18 ) and the inlet pipe cleaning system ( 43 ) the entire device in the vector direction shown ( 27 ) at.

5 is a schematic representation of the device according to the invention in the head driver ( 28 ) by the external drive ( 22 ) via the coupling ( 23 ) and the wave ( 25 ) is driven.
