  • the object of the invention is to provide a steam device of the type mentioned at the outset, which is very easy to operate. This object is achieved according to the invention with the steam device mentioned at the outset in that the rinsing mode is automatically controlled by the rinsing unit of the control device and is carried out for a specific period of time. Further embodiments of the invention are shown in dependent claims 2-14.
  • cleaning agent mode clear water with added cleaning agent is applied via the application device.
  • the detergent is a chemical cleaning additive, which is provided in particular in liquid form via the cleaning agent supply device. After the end of the dispensing process, there is usually still a residue of cleaning agent in the dispensing device.
  • an aerosol can be formed as a result of the steam being applied to the cleaning agent residues in the dispensing device.
  • the aerosols are discharged by the discharge device.
  • a rinsing unit is provided, by means of which a rinsing mode can be carried out.
  • the discharge device is rinsed with clear water, which means that most of the cleaning agent residues in the discharge device are removed. In the event of subsequent operation in vapor mode, this prevents or greatly minimizes the formation of aerosols.
  • the discharge device comprises a first coupling point for steam, which is in fluidic connection with the steam generator, a second coupling point for clear water, which is in fluidic connection with the clear water supply device, and a third coupling point for a mixture of clear water and Includes cleaning agent, which is in fluid communication with the mixing device.

  • cleaning agent residues can be effectively removed from the dispensing device in a rinsing mode.
  • the second launch point with the third launch point coincides, resulting in a simple structural design. For example, only one common line for clear water and for the mixture of clear water and cleaning agent has to be provided downstream of a mixing device. This one line can then be effectively flushed even if only clear water is fed through it.
  • the clear water supply device can include a connection via which clear water can be coupled. It is favorable if the clear water supply device is or includes a clear water tank. This means that a steam device that is independent of an external water supply can be implemented.
  • the cleaning agent supply device comprises a cleaning agent tank or is a cleaning agent tank.
  • a liquid cleaning agent is held in the cleaning agent tank as a chemical cleaning additive.
  • control device sets a specific duration of the flushing process. This ensures reproducible effective flushing in order to remove cleaning agent residues from the dispensing device with high efficiency.

  • a hydrovapo mode can be advantageous for certain cleaning purposes.
  • the dispensing device includes at least one pipe and/or hose.
  • a cleaning process can be carried out via this or these at a distance from a body of the steam device.
  • the steam device includes a controllable first valve, which is connected downstream of the steam generator and which is controlled by the control device, with the first valve in particular being multi-stage.

This allows the admixture of cleaning agent to clear water to be adjusted in order in particular to operate the steam device in the cleaning agent mode.
  • control device sets or is set on this that when the third valve is open, a first valve, which is connected downstream of the steam generator, is closed. In this way, it can be ensured in an effective manner that no steam is applied to the dispensing device by cleaning agent in the cleaning agent mode.
  • the mixing device is connected downstream of the third valve and a second valve, which is connected to the clear water supply device.
  • the third valve When the third valve is closed, clear water can be fed through the mixing device (without mixing) in order to couple this into the dispensing device.
  • the third valve and the second valve are open, a mixture of clear water and cleaning agent can be produced at the mixing device.
  • the control device sets that the third valve can only be open if the second valve is also open.
  • a first pump for conveying clear water and/or a mixture of clear water and cleaning agent is advantageously provided in the dispensing device, with the first pump being controlled by the control device.
  • the first pump is connected downstream of the mixing device. Fluid (clear water or a mixture of clear water and cleaning agent) can thus be effectively discharged with the discharge device.
  • a second pump is provided for conveying clear water from the clear water supply device to the steam generator. Clear water can then be conveyed to the steam generator in order to provide a sufficient quantity of clear water for steam generation.
  • the steam device is designed as a suction device and is therefore designed as a steam suction device with a suction unit and a suction connection. Because it is designed as a suction device, a suction process can be carried out. In particular, dirty water can be sucked in. This means that flushing liquid, with which the discharge device was cleaned of cleaning agent residues, can be sucked in again directly. As a result, the "outside world" is minimally burdened by the operation of the vaping device in purge mode.
  • the steam device then has at least one dirty water tank, which can hold dirty water that has been sucked in.
  • a suction line device is at least partially mechanically connected to the dispensing device. This results in easy handling for an operator. He only has to hold one element, which includes part of the suction line device and the dispensing device.

  • an operator can set the appropriate operating mode in a simple manner.
  • the selector switch is in operative contact with the control device.
  • Appropriate operating modes are specified by the control device through appropriate activation of valves, pumps, etc., through settings on the selector switch.
  • the control device After starting the rinsing mode, the control device carries this out automatically, which means that the rinsing mode itself can then be operated without operator access. It is advantageous if the rinsing mode is started manually by the operator himself, for example using a switch which is arranged on or in the vicinity of a handle. In the flushing mode, flushing liquid basically comes out of a mouth of the discharge device on. A manual start allows an operator to prepare for this.
