Definitions

  • the invention relates to a laundry drying device with a fluff filter and a method for operating such a laundry drying device.
  • the cleaning fluid is also used to transport the lint away from the lint filter to a depot.
  • the fluff and the condensate water are separated again by filtration.
  • the lint volume already deposited from previous cleaning operations and, for a short time, the lint-laden liquid from the cleaning operation that has just been carried out must be accommodated in the depot.
  • a backwater can form in the depot, which can even lead to an overflow of the lint-laden liquid from the depot.
  • the WO 2008/119611 A1 describes a method and a device for cleaning a component, in particular an evaporator of a condenser device, as well as a washing machine or tumble dryer with such a device.
  • a component in particular an evaporator of a condenser device
  • Condensate water which is obtained in the process air circuit from the drying of damp laundry and is collected in a condensate water pan, is routed to a rinsing container provided above the evaporator and released as a gush of water to the relevant component when it suddenly opens on the outlet side.
  • a laundry drying device with a component to be cleaned, in particular arranged within a process air circuit, in the form of a heat exchanger and with an elevated rinsing container, wherein a cleaning liquid can be dispensed from the rinsing container through a controllable valve to the component to be cleaned.
  • From the DE 10 2005 014 842 A1 discloses a circulating air tumble dryer with a heat pump, which has two heat exchangers arranged in the circulating air, which are to be flooded with water to ensure rapid temperature and pressure equalization before the heat pump is started up.
  • the water can be condensate that has accumulated in a drying process and has been stored in a collection container. From here it can be routed to the heat exchangers via a device for opening and shutting off the water outlet and a distribution device.
  • a corresponding laundry drying device and a method for its operation are to be specified.
  • the laundry drying appliance is equipped with a component to be cleaned, which is arranged in particular within a process air circuit, and with a rinsing container provided above the component to be cleaned, with a cleaning liquid being able to be dispensed from the rinsing container through a controllable valve to the component to be cleaned and with the valve being on the
  • the basis of an amount of cleaning liquid in the washing container that can be controlled, in particular can be actuated, is such that only an amount of cleaning liquid that is just sufficient for effective cleaning is released.
  • the valve can be controlled in such a way that during a cleaning process the desired amount of cleaning liquid can be drained from the rinsing container with great accuracy to the component to be cleaned.
  • an amount of cleaning liquid that is just sufficient for effective cleaning can be dispensed, which means that a collection container (fluff depot, condensate water pan, etc.) downstream of the component to be cleaned can only be filled with the smallest possible amount cleaning liquid is filled. This applies in particular in the event that, before a cleaning process, the washing container is filled with a larger quantity of cleaning liquid than is just sufficient for a cleaning process.
  • the valve is for its actuation with a control device, in particular central
  • Control device connected to the laundry drying device.
  • the control device is equipped with logic for calculating the amount of cleaning liquid in the washing container.
  • the control device can be functionally connected to at least one sensor, with at least one measured value of the at least one sensor being able to serve as an input variable or variables for the calculation.
  • the at least one sensor can include, for example, at least one load sensor, at least one humidity sensor (e.g. for measuring a temperature of process air discharged from a laundry drum), at least one temperature sensor (e.g. for measuring a temperature or a temperature difference in a heat exchanger), etc.
  • the valve can be controllable as a function of a load in the laundry drying appliance. This exploits the fact that the controller of some tumble dryers is already able to recognize the load or load quantity in a laundry drum of the tumble dryer.
  • the amount of condensate that occurs during a drying cycle can be at least roughly predicted from the loading values. From this, in turn, the amount of condensate water that will be in the rinsing tank for cleaning can be determined. With this solution, the amount of cleaning liquid (amount of condensate water, possibly with metered fresh water supplied) can be estimated with sufficient accuracy using a method known in principle, which enables a particularly inexpensive implementation.
  • valve can be controlled as a function of a predetermined degree of drying or a specific dry state (e.g. iron dry, cupboard dry, etc.). With knowledge of the degree of drying and thus the residual moisture remaining in the laundry, the expected amount of cleaning liquid in the washing container can be corrected accordingly.

  • valve can be controlled as a function of a preselected type of textile (wool, cotton, etc.). Because even if you know the type of textile and thus the residual moisture remaining in the laundry due to the textile, the expected amount of cleaning liquid in the rinsing container can be corrected.
  • a preselected type of textile wool, cotton, etc.
  • valve is advantageously controlled as a function of a drying time.
  • the drying speed is essentially the same regardless of the load and an initial residual moisture content.
  • the amount of liquid already collected in the washing compartment can therefore be directly inferred from the drying time that has already elapsed.
  • the valve can be controllable as a function of a measured filling level of the washing container and/or the collecting container.
  • the filling level in the rinsing tank can be determined, for example, using a magnetic float with a read switch cascade, Hall sensor scanning or magnetoresistive sensor scanning, or by direct level scanning, e.g. using capacitive, optical or acoustic sensors.
  • the valve can be controlled with regard to an opening duration.
  • the amount of cleaning liquid provided for the cleaning can be metered in that the opening duration of the valve can be adjusted accordingly.
  • the advantage here is that an opening process can be carried out very easily and quickly by opening the valve completely.
  • valve can be controllable with regard to a flow cross section.
  • the amount of cleaning liquid provided for the cleaning can be metered in that the flow cross section released by the valve can be adjusted accordingly.
  • the laundry drying device can have a collecting tank in the form of a condensate water pan, in which condensate water produced in the process air circuit by drying damp laundry can be collected, this condensate water being able to be fed to the rinsing tank as the cleaning liquid.
  • the feed can be implemented, for example, by means of a pump.
  • the condensate water pan can be fluidly connected upstream of a lint depot, wherein the lint depot can have a drain equipped with a lint retaining element.
  • the lint retaining element can have a filter, for example.
  • the fluff depot can prevent the condensate water tray and a pump that may be connected to it from becoming clogged.
  • the fluff depot In order to achieve a compact design, it can be advantageous for the fluff depot to be integrated into the condensate water tray as an antechamber. Then the fluff depot can be viewed as an antechamber of the condensate water tray.
  • the lint depot In order to remove the lint conveniently and also without any problems by an end customer, it can be advantageous for the lint depot to be removable.
  • control of the valve includes opening the valve with an opening duration depending on the determined quantity of cleaning liquid.
  • control of the valve includes opening the valve with a flow cross section as a function of the determined quantity of cleaning liquid.
  • valve It has been found to be advantageous for the valve to be opened until a maximum quantity of approximately 0.5 l to 1 l of the cleaning liquid has been drained to the component to be cleaned. This results in good cleaning performance with low consumption of cleaning fluid at the same time, and there is no risk of the collection container overflowing.
