  • the household drying device comprises an electronic control device for controlling the process air blower and the rinsing system, which is set up to activate the process air blower at least temporarily during the rinsing process.
  • the washing liquid used for cleaning the component is entrained by the process air flow generated by the process air blower. This improves the cleaning of the component and also allows a cleaning of possibly downstream of the component arranged further components of the process air system.
  • An object of the invention is to improve an operation of a drying device of the type mentioned.
  • a process air arrangement according to the invention for a drying device in particular a washer dryer or a tumble dryer, accordingly comprises at least one process air blower, which is designed as a radial blower and has a housing which widens spirally with respect to a drive axis of a rotor wheel of the process air blower to a process air outlet.
  • the process arrangement according to the invention comprises at least one process air duct, which adjoins the process air outlet in a fluid-conducting manner, and at least one additional process air duct arranged radially on the outside of a part of the housing and adjacent to a section of the process air duct.
  • At least one outlet opening is arranged on a radially outer wall of the housing and at least one inlet opening is arranged on the process air channel, with the additional process air channel communicating in this way connected to the outlet breakthrough and the inlet breakthrough that process air via the outlet breakthrough from the housing in the additional process air channel and can enter via the inlet opening from the additional process air duct in the process air duct.

  • a process air duct connected upstream of the process air blower on the suction side or is drawn in by it.
  • at least one component, in particular a heat exchanger of a heat pump, of the drying device can be arranged. Since the process air blower is designed as a radial fan, the process air guided inside the spiral housing exits radially or tangentially out of the process air outlet of the housing. The process air thus emerging from the housing passes directly into the process air channel which adjoins the process air outlet in a fluid-conducting manner. About this, the process air can be fed to a washing drum of the drying device in order to be able to flow through them for drying laundry.
  • part of the process air conducted in the housing can exit the housing through the opened outlet opening and enter the additional process air channel. This is supported by the centrifugal forces acting on the process air in the housing.
  • the process air flowing through the additional process air duct can exit from the additional process air blower via the inlet opening and enter the process air duct.
  • the process air can thus be divided in the process air arrangement according to the invention in two different process air flows, namely a process air flow that does not enter the additional process air duct and leaves the housing via the process air outlet, and another process air flow that passes through the additional process air duct. This makes possible in particular a separate treatment of the further process air flow within the additional process air duct.
  • the process air drawn in by the process air blower can be laden with moisture.
  • the process air arrangement according to the invention is used in the case of an above-mentioned drying device in the form of a washer-dryer or a tumble dryer, the moisture contained in the process air can be obtained from a flushing process come during which the process air blower has been at least partially activated.
  • the flushing liquid used for cleaning the component is entrained by the process air flow generated by the process air blower in order to achieve improved cleaning of the component and possibly additional cleaning downstream of the component arranged further components.
  • the process air flow is thus formed as a multiphase flow, in particular as a two-phase flow with a gaseous phase formed by air and a liquid phase formed by the cleaning fluid, which may be contaminated with lint.
  • the centrifugal forces acting on the two-phase flow are different due to the different density of the two phases.
  • the different centrifugal forces and the different inertia of the two phases cause the liquid phase is pushed radially outward than the gaseous phase.
  • the liquid phase tends increasingly to enter the additional process air duct via the outlet opening.
  • the flow paths of the two phases are separated from each other. This separation is further facilitated by the fact that smaller liquid droplets in mutual contact combine to form larger liquid droplets, which have a higher inertia.
  • the two-phase flow with the higher liquid content is passed through the additional process air channel, while the two-phase flow with the lower liquid content remains in the housing and exits the process air outlet.
  • the two-phase flow with the higher liquid content can be treated in the additional process air duct to selectively stop the contaminated with the lint liquid phase or liquid as far as possible and thus prevent it from entering the process air duct and this downstream washing drum of the drying device.

  • the separation effect of the additional process air channel can be increased with the separation construction.
  • With the separation construction there is a multiple flow diversion of the moister two-phase flow flowing in the additional process air duct.
