  • the distributor disc can therefore be used advantageously for a variety of different applications.
  • the distribution disc is only partially arranged in the distributor housing.
  • the cooking appliance also allows the cleaning liquid to be circulated, so that less cleaning liquid is used and cleaning is therefore more efficient.
  • the method also enables different cleaning programs to be carried out to clean the cooking chamber as required.
  • the rotational speed of the distribution disc of the distribution system By varying the rotational speed of the distribution disc of the distribution system, the throwing curve of the cleaning liquid can be set as required, so that areas of the cooking chamber arranged at different distances from the distribution system can be reached in an advantageous manner using the cleaning liquid released by the distribution system.
  • the aforementioned variation in the rotational speed also enables the individual areas of the cooking chamber to be exposed to cleaning liquid in an alternating and therefore pulsating manner.
  • each of the wings forms an acute angle with the longitudinal axis of the pivot pin, preferably that each of the wings has a first wing section starting from the base plate and a second wing section adjoining the first wing section in the direction of a free end of the wing. It is provided that the two wing sections form different angles with the base plate. In this way, a targeted guidance of the cleaning fluid is possible. For example, it is possible to direct the cleaning fluid in a first direction of rotation of the distributor disc onto the base plate in order to apply cleaning fluid to the side cooking chamber walls and a cooking chamber wall designed as a cooking chamber floor.
  • the cleaning fluid can be directed by means of the obliquely running wings onto a cooking chamber wall designed as a cooking chamber ceiling.

  • the distributor disc with the base plate is dimensioned sufficiently large to distribute the cleaning fluid in the cooking chamber in the previously defined manner.
  • the distributor disc with the base plate is dimensioned as small as possible so that unwanted heat discharge from the cooking chamber can be reduced to a small extent by means of the distributor disc.
  • a distributor disc that is as small as possible also has the advantage that a rotary movement of the distributor disc requires less torque, so that, for example, an electric drive for any shaft connected to the pivot pin in a torque-transmitting manner needs to be designed to be less powerful.
  • the energy consumption during operation of the distribution system is also reduced accordingly.
  • the noise emission during operation of the distribution system is also effectively reduced.

  • the pump can also be used to control the intensity of the backwash of the drain.
  • the pump for backwashing the drain can be operated at maximum power in order to pump any solids blocking the drain as far away from the drain as possible.

  • an advantageous development of the aforementioned embodiment of the method provides that the pump conveys the cleaning liquid through the drain against the circulation direction of the circulation system during the backwash state. This makes it possible to backwash the drain using the cleaning liquid, for example, without additional lines or the like.
  • An alternative or additional development of the cooking appliance provides that the pump is designed and arranged in such a way that when the pump is switched off, gravity-induced backflow of the cleaning liquid is possible. This enables backwashing of the drain of the cooking chamber against the circulation direction of the circulation system even without the pump being operated, by using the amount of cleaning liquid present in the supply line, in the pump and in the drain line to backwash the drain.
  • an advantageous development of the method provides that the pump is switched off during the backwash state in such a way that the cleaning liquid is conveyed through the drain by means of gravity against the circulation direction of the circulation system.

  • This design also makes it possible to minimize the space required for the distributor system in the cooking chamber and/or to enable more even wetting of the cooking chamber walls of the cooking chamber that border the cooking chamber, i.e. the cooking chamber floor, the cooking chamber ceiling and the side cooking chamber walls.

  • the shaft connected to the pivot pin of the distributor disc preferably connected in a torque-transmitting manner, and an electric drive of the cooking appliance that drives this shaft are effectively protected from heat radiation from the cooking chamber.
  • the energy efficiency of the cooking appliance is also increased accordingly. This also results in a visually pleasing overall impression of the cooking chamber.
  • the distribution system can thus have an electric drive connected to the pivot pin of the distribution system in a torque-transmitting manner.
  • This allows the pivot pin and thus the distribution disc to be driven independently of the supply of cleaning fluid.
  • the throw curve of the cleaning fluid can be adjusted independently of the amount of cleaning fluid supplied to the distribution disc, for example by means of the rotational speed of the distribution disc, i.e. its rotational speed.
  • the inlet opening and the distribution disc of the distribution system are designed and arranged in such a way that the distribution disc can be driven by means of the cleaning fluid.
  • the distribution disc can be driven independently of an electric drive of the distribution disc.
  • an electric drive of the distribution disc can generally be dispensed with.
  • the rotational speed of the distributor disc can be changed by varying the flow rate of cleaning fluid through the inlet opening of the distributor system.
  • the inlet opening in particular together with the inlet line in the area of the inlet opening, is aligned in such a way that a fluid flow emerging from the inlet opening is oriented radially to the axis of rotation of the distribution disk.

  • the cooking appliance according to the invention provides that the distribution system is arranged approximately centrally on a cooking chamber wall of the cooking chamber designed as a cooking chamber ceiling, preferably that the distribution system is arranged essentially vertically above the drain.
  • This is a particularly favorable arrangement of the distribution system relative to the cooking chamber of the cooking appliance, as this ensures that the individual areas of the cooking chamber are well supplied with cleaning fluid.
  • the preferred embodiment of this development also has the advantage that the drain can be cleaned using the distribution system without additional construction or circuitry effort. According to the invention, cleaning of the The drain is realized in a particularly simple way in that the cleaning liquid from the distribution system can be directed directly to the drain due to gravity. In particular, with this arrangement of distribution disc and drain, vertically one above the other, the cleaning liquid can drip or flow from the distribution disc directly to the drain when the distribution disc is not moving.
  • the distributor disc and the drain are at least 15 centimeters apart, preferably more than 20 centimeters. This distance has proven to be sufficient so that the cleaning liquid dripping or flowing from the distributor disc has sufficient kinetic energy when it hits the drain or a sieve of the drain to break up the suspended matter deposited there and thus automatically remove and/or prevent a blockage of the sieve and/or the drain.
  • the inlet line is additionally connected to the drain in a flow-conducting manner by means of a bypass line of the circulation system, wherein the bypass line can be blocked in non-bypass mode by means of at least one valve.

This enables a highly efficient way of cleaning the drain that is an alternative to using the cleaning liquid.
  • the steam line comprises the inlet line and the outlet line or the outlet line, wherein the inlet line or the outlet line can be blocked in the steam cleaning mode by means of at least one valve in such a way that no steam can escape from the inlet opening of the distribution system.
  • the inlet line and the outlet line or the drain line can be used to conduct the steam from the steam generator to the drain, so that the need for additional steam lines is minimized.
  • the steam can not only be used to clean the drain, but also to clean and sterilize the inlet line and the drain line or the drain line.
  • an advantageous further development of the method provides that the steam generator is connected to the drain in a flow-conducting manner during the steam cleaning operation by means of the steam line indirectly, by means of the inlet line and the drain line or the drain line, or directly, so that steam generated by means of the steam generator is conveyed through the drain.
  • the cleaning program is designed such that at the beginning of the at least one cleaning cycle the distributor disk is operated at a maximum rotational speed of the cleaning cycle and the rotational speed is reduced after a predetermined period of time. Due to the maximum rotational speed at the beginning of each of the at least one cleaning cycle, for example, any inertia, contamination or sticking of the distributor system is overcome or the rotational axis is prevented from jamming. The subsequent reduction in the rotational speed, for example, reduces the consumption of electrical energy.
  • a maximum speed of the distributor disk that correlates with the maximum rotational speed of the distributor disk can be, for example, 5000 revolutions per minute. The speed can subsequently be reduced, for example, continuously or discontinuously, to a value of 0 revolutions per minute.

  • This makes it possible to apply a surge of cleaning fluid to the cooking chamber walls, i.e. the cooking chamber floor, the cooking chamber ceiling and the side cooking chamber walls, in a structurally and circuit-technically simple manner. Accordingly, the mechanical cleaning of the cooking chamber walls by means of the cleaning fluid is significantly improved.
  • the aforementioned reduction can take place in stages, namely a reduction from the maximum speed of 5000 revolutions/minute to a first intermediate speed of 1000 revolutions/minute in a period of 30 seconds, followed by a sudden increase in the speed from the first intermediate speed of 1000 revolutions/minute to a second intermediate speed of 1500 revolutions/minute within less than a second or a few seconds, thereafter a reduction in the speed from the second intermediate speed of 1500 revolutions/minute to an upper speed of 700 revolutions/minute within a period of about 60 seconds and finally a sudden reduction in the speed from the upper speed of 700 revolutions/minute to a lower speed of preferably 0 revolutions/minute within less than a second or a few seconds.
  • the at least one cleaning cycle stored in the cleaning program can be freely selected within wide, suitable limits.
  • An advantageous development of the method provides that the at least one cleaning cycle has a sawtooth-like profile in a speed-time diagram. In this way, the cleaning fluid is applied to the cooking chamber walls in a pulsating manner throughout the entire cleaning cycle.
  • the maximum speed of the distributor disc at the beginning of a cleaning cycle can be 5000 revolutions/minute, as above, and then gradually reduced to the upper speed with a value of 700 revolutions/minute within 45 seconds, then gradually increased again from the upper speed with 700 revolutions/minute to the maximum speed with 5000 revolutions/minute within 45 seconds, then gradually reduced again to the upper speed with a value of 700 revolutions/minute within 45 seconds, then gradually increased again from the upper speed with 700 revolutions/minute to the maximum speed with 5000 revolutions/minute within 45 seconds, then gradually reduced again to the upper speed with a value of 700 revolutions/minute within 45 seconds and finally suddenly increased from the upper speed with 700 revolutions/minute to a lower speed with preferably 0 within less than a second or a few seconds. revolutions/minute can be reduced.
