  • the filter and / or separation system intermittently or constantly, in particular during the method step c) is switched on.
  • the invention is therefore based on the surprising finding that it is due to the special Arrangement of the shut-off device downstream of the cooking chamber drain and through the two various parking positions of this shut-off device with the cleaning arrangement according to the invention is possible, for a heavily contaminated fluid, in particular cleaning fluid, via the Garelloabfluß first remove from the cooking appliance, and on the other hand, after removal of the heavily contaminated fluid, new or remaining To circulate fluid inside the cooking appliance to clean it.
  • Arrangement is thus avoided in particular that larger dirt particles, such as For example, grease, Gargutreste and / or lime, during a cleaning process circulated in the cooking appliance and remain there after completion of the cleaning. Consequently Overall, an improved cleaning effect is achieved.
  • FIG. 1 shows a cooking appliance 1, a cooking chamber 2 and an air duct 3 of the Cooking chamber 2 separated fan room 4 with a fan 5 includes.
  • the fan 5 can are driven by a motor 6 and is axially surrounded by a heater 7.
  • the Cooking appliance 1 further comprises a ventilation / venting channel 8 with a closable flap 8a.
  • An electrical supply line 9, which leads to a controller 10, which via control lines 11 the cooking appliance 1 can control, in particular in dependence on the output values of three Sensors 11a, 11b, 11c are further included in the cooking appliance 1.
  • the cooking chamber 2 has a cooking chamber drain in its bottom area 16, which opens into a container 17, both as an extinguishing box and can be used as a wash liquor container. Downstream of the Garraumablaufs 16, namely in the exit area of the container 17, a shut-off device 20 is arranged, from which a drain line 18 and a circulation line 19 lead away.
  • the circulation line 19 comprises Furthermore, a pump 21, the fluid from the circulation line 19 back into the cooking chamber 2, namely via a cooking chamber inlet 22, can introduce.
  • a cleaning arrangement according to the invention are thus the quenching box 17 and the wash liquor 17 formed in one, so that over the Shut-off device 20 downstream of the same a fluid from the cooking chamber 2 either over drains the device drain 18 or circulated back into the cooking chamber 2.
  • FIG. 2 schematically shows a second embodiment of the cleaning arrangement of the present invention Invention illustrated. From the bottom area of one with a cooking chamber inlet 29 provided cooking chamber 30 performs a cooking appliance 31 away, both with a first Line 32 for connection to a cooking appliance drain 33 as well as a second line 34 for connection to the cooking chamber 30, namely on the cooking chamber 29, in conjunction located on the one hand via a Ablöschkasten 36 and the other over a wash liquor tank 35, a pump 39, and a pipe 37.
  • shut-off device 38 in the second Line 34 is provided, these being substantially perpendicular below the cooking chamber drain 31 is arranged.
  • This shut-off device 39 is preferably a 3/2 shut-off device, which are adjusted when using the cleaning arrangement according to the invention as follows can.
  • shut-off device 38 If the shut-off device 38 is closed, so fluid, in particular cleaning fluid with Protective particles from the cooking chamber 30 is not in the wash liquor tank 35 and thus over the pump 39 and the line 37 are returned to the cooking chamber 30 again. Fluid, that is discharged from the cooking chamber 30 via the cooking chamber 31, is rather on the Drained line 32, enters the Abschöschkasten 36 and finally in the Garausabfluß 33.
  • the closed position of the shut-off device 38 is to be set in particular then if a cleaning process for the cooking appliance has just been started, first coarse dirt particles, such as grease, Gargutreste, lumps or the like, directly from the cooking chamber 30 dissipate. With appropriate position of the shut-off device 38 is therefore avoided that fluid with coarse dirt particles in the Wash liquor tank 35 and thus can get back into the cooking chamber 30, where the Dirt, despite cleaning process, even after its completion can remain.
  • shut-off device 38 passes Fluid from the cooking chamber 30 due to gravity directly into the wash liquor container 35 and can be circulated via the pump 39 in the cooking appliance for cleaning the same.
  • the Implementation of this second method step is indicated in particular if already coarse dirt particles have been removed from the cooking appliance.
  • the cleaning arrangement according to the present invention and with this cleaning arrangement feasible cleaning methods thus allow a greatly improved cleaning a cooking appliance.
  • FIG. 3 shows a third embodiment of the cleaning arrangement according to the invention, in FIG which reference symbols which have already been used in FIG. 2 have the same meaning exhibit.
  • the cooking chamber drain opens 31 in a first line 32 and a second line 34.
  • the shut-off device 38 is arranged in the first conduit 32.
  • an overflow stop 40 is also provided in front of the wash liquor tank 35.
  • the cleaning arrangement according to Figure 3 can be used as follows.
  • the shut-off device 38 is opened, and as already in With reference to Figure 2, heavily contaminated fluid may drain directly over the cooking appliance 33 are removed from the cooking appliance.
  • the shut-off device 38 are closed, so that the fluid in the range of Garraumablaufes 31 first accumulates in front of this shut-off 38 and, as soon as the filling height the fluid has reached the height of the overflow stop 40, the fluid in the wash liquor container 35 flow to returned via the pump 39 back into the cooking chamber 30 become.
  • the open position of the shut-off device 38 prevents the overflow stop 40th a fluid inlet into the washing liquor tank 35.
  • overflow stop 40 can also larger dirt particles even in the closed position of the shut-off device 38 thereof to be prevented from entering the cooking chamber 30 via the wash liquor container 35. These Dirt particles can later, with the position of the Absperr engaged 38 over the Garausabfluß 33 are washed away.
  • the shut-off device 38 is provided with an emergency overflow and so downstream of the cooking chamber 31 arranged that the emergency overflow slightly above the Top edge of the overflow stop 40 is located.
  • an emergency overflow for example, an additional Be hole through the shut-off 38, which is preferably not closable.
  • the shut-off device is operated by a motor and is connected to a control and / or regulating device of the cooking appliance in operative connection.
