Definitions
- the invention relates to a device and a method for cleaning a arranged in a process air cycle of a dryer component and a dryer with such a device.
- the invention relates in particular to a device and a method for cleaning a component arranged in a process air cycle of a dryer with a rinsing liquid, wherein the device has a depot for receiving the rinsing liquid after its contact with the component to be cleaned and a sensor chamber in which a filling level sensor is arranged , having.
- the invention more particularly relates to a dryer with such a device. Dryers are understood here to mean both a washer-dryer and a tumble dryer.
- a washer-dryer is a combination device that has a washing function for washing laundry and a drying function for drying laundry.
- a tumble dryer only has a drying function for drying laundry.
- a dryer air (so-called process air) is passed through a fan via a heater in a wet laundry containing drum as a drying chamber.
- process air In the drum are moist, to be dried items of laundry.
- the hot air absorbs moisture from the laundry to be dried.
- the now moist process air is fed into a heat exchanger, which is usually preceded by a lint filter (also called a "lint filter”), in which the moist process air is added (eg air-to-air heat exchanger or heat sink of a heat pump)
- the condensed water (condensate) is then usually collected in a condensate pan, and the cooled and dried air is returned to the heater and then to the drum.
- DE 10 2007 049 061 A1 describes a method and a device for cleaning a component arranged within a process air cycle of a washer or dryer, in particular an evaporator of a condenser device, in the condensate water obtained in the process air cycle from the wet laundry and in a condensate pan is collected, is passed to a rinsing chamber of a collecting vessel provided above the evaporator.
- the collecting container also has an overflow region serving as a storage chamber. From the outlet side of the rinsing chamber, the condensate water is released by abrupt opening as a flood of water to said component and then collected again in the condensate pan.
- DE 10 2010 042 495 A1 discloses a cleaning device for a component subjected to lint, which has a container for receiving rinsing liquid for rinsing the lint from the component, wherein the container comprises a rinsing chamber and a storage chamber.
- the rinsing chamber has an inlet, via which rinsing liquid can be conveyed into the rinsing chamber by means of a pump, wherein a sieve for cleaning the rinsing liquid is arranged in the region of the inlet.
- the cleaning device has two processes.
- the first drain which is arranged on the other side of the screen as the inlet, serves to supply the cleaned flushing liquid to the component to be cleaned.
- the second drain which is arranged on the same side of the screen as the inlet, serves for the discharge of superfluous Uncleaned rinsing liquid to prevent unwanted overflow of the rinsing liquid.
- the superfluous rinsing liquid is passed into the storage chamber, wherein the rinsing liquid, when the storage chamber is filled, in turn, is discharged into the bottom group of the dryer.
- the rinsing liquid in the known internal cleaning devices for components arranged in the process cycle of a dryer which use a rinsing liquid, the rinsing liquid must be suitably collected and removed after the component has been rinsed. In particular, if the catch is made by the condensate pan, it must be ensured that it does not overflow. Even with a continuous outflow from the collecting container for the rinsing liquid monitoring is necessary because the rinsing liquid entrains the rinsed lint, which can lead to obstructions in the drain and thus overflow of the collection container.
- the level of the rinsing liquid in the collecting container is too high, it is possible in the collecting container for the component to be cleaned to remain in contact with lint, depending on the structural arrangement, with already used rinsing water.
- the use of level sensors is known.
- the level sensor is arranged in a separate chamber of the collecting container, wherein the chamber is filled only when exceeding a certain filling level with rinsing liquid and the inflow opening is equipped in the chamber with a sieve, which prevents the ingress of dirt and its attachment to the sensor.
- the screen can affect the inflow into the chamber state-dependent, so that in particular a contamination of the screen can lead to a delayed or reduced inflow and thus to a faulty level detection.
- the object of the present invention was to provide a cleaning device, a cleaning method and a corresponding dryer, in which the fill level in the collecting container, which serves to receive the rinsing liquid after its contact with the component to be cleaned, can be reliably determined.
- the disposal of the contaminated flushing liquid can be ensured, so that a component arranged in the process air duct can be cleaned in an improved manner.
- the invention thus relates to a device for cleaning a arranged in a process air cycle of a dryer component with a rinsing liquid, which has a depot for receiving the rinsing liquid after their contact with the component to be cleaned and a sensor chamber in which a level sensor is arranged, wherein
- the sensor chamber is arranged outside the depot and with this via an opening system hydraulically communicating;
- a supply system of the cleaning device has a first inlet directly to the sensor chamber and a second inlet to the component to be cleaned; iii. the supply system and the opening system are designed so that per unit time, a larger volume of the washing liquid can flow into the sensor chamber via the first inlet as can flow out of the sensor chamber through the opening system in the depot and
- the cleaning device is designed so that when filling the level of the washing liquid in the sensor chamber has reached at least a height corresponding to the upper limit of the opening system before the level of the washing liquid in the depot has reached a height corresponding to the lower limit of the opening system ,
- the device according to the invention for cleaning (hereinafter also abbreviated to “cleaning device”) operates with a rinsing liquid, which is an aqueous liquid, which generally comprises condensate and / or tap water from the water supply
- a rinsing liquid which is an aqueous liquid, which generally comprises condensate and / or tap water from the water supply
- additives such as other solvents (for example alcohols) or surface-active agents may be added to the rinsing liquid.
- the rinsing liquid can be provided in various ways.
- the cleaning device is preferably connected to a water supply and / or a condensate tray.
- these are also supplied from the depot of the cleaning device via a corresponding connection to the supply system.
- water supply is meant herein generally a water supply of home-available tap water which is normally supplied at a tap water pressure of at least 3 bar, but sometimes at a higher pressure, e.g. with 6 bar, is provided.
- connection with a water supply allows the cleaning with fresh water, which contains no impurities.
- the connection with a condensate tray and / or a depot is stored in the rinsing liquid from previous rinses, allows the use of accumulating in the dryer condensate or rinse liquid already used. Since the condensate in the condensate pan or already used rinsing liquid in the depot usually contain lint, a filtration and / or an admixture of fresh water from a water supply is preferably carried out prior to their use in the cleaning device.
- the water supply, the condensate tray and / or the depot can be connected directly to the supply system of the cleaning device, possibly with the interposition of a pump and / or a filter.
- the fresh water from the water supply and / or the condensate or already used rinsing liquid can also initially reach a rinsing container, which in turn is connected to the supply system of the cleaning device.
- the cleaning device is preferably operated directly or shortly after completion of a drying operation of wet laundry to be dried, since at this time on the component, such as a heat exchanger, adhesive contaminants, especially lint, are still wet or dissolved and are relatively easily removed by the dispensed rinse liquid .
- the component such as a heat exchanger
- condensate tray or rinse tanks are usually filled with condensate that can be used to clean the component.
- the cleaning device according to the invention has a depot for receiving the rinsing liquid after its contact with the component to be cleaned.
- the depot is a collecting container for the rinsing liquid after rinsing the component.
- the depot is usually located below the component to be cleaned.
- the depot has a liquid drain (also called “drain").
- This may be a passive liquid flow, in which the liquid is drained only by utilizing gravity, or the liquid can be actively removed from the deposit, for example by a pump.
- the combination of both variants is possible, for example by a correspondingly dimensioned passive liquid flow and the operation of a pump on the same process or on different processes of the depot.
- the depot corresponds to the condensate tray or is structurally connected to it, so that it forms part of the condensate tray, wherein it is particularly preferred that the depot corresponds to the condensate tray.
- the condensate tray can serve as a depot for receiving the rinsing liquid after their contact with the component to be cleaned by their spatial arrangement simultaneously.
- the cleaning device has a sensor chamber.
- the sensor chamber is a container which can receive rinsing liquid and in which a level sensor (hereinafter also referred to as "sensor") is arranged, the type of sensor being not limited according to the invention, as long as the sensor contains information about the level of the rinsing liquid
- the sensor is an electrode which can detect a resistance of the medium surrounding the electrodes When the medium surrounding the electrodes changes, for example during the filling of the sensor chamber from air into rinsing liquid, that of Thus, such a sensor provides information on whether a certain level of flushing liquid is reached or not.
- sensors for filling level detection can also be used according to the invention, such as optical sensors, pressure sensors, etc.
- it can be determined by the sensor how long flushing liquid is applied to the sensor, for example by a single signal that over the duration ⁇ t of Contact of the sensor with the liquid stops or by several, for example, two signals at the times t- ⁇ , the beginning of the contact with the rinsing liquid, and t 2 , the end of the contact with the rinsing liquid, from which At can be determined.
- the cleaning device has a supply system, which comprises a first inlet directly to the sensor chamber and a second inlet to the component to be cleaned.
- the rinsing liquid from the water supply, the condensate pan and / or the depot passes directly or via a rinsing container, possibly with the interposition of a pump and / or a filter in the supply system of the cleaning device.
- the rinsing liquid volume is divided such that a portion of the rinsing liquid is passed through the first inlet without contact with the component to be cleaned directly to the sensor chamber and another part of the rinsing liquid is passed through the second inlet to the component to be cleaned.
- the first and second inlets are therefore two different, correspondingly configured cavities, such as, for example, channels, pipes or connections.
- part of the rinsing fluid volume flows directly via the first inlet of the supply system to the sensor chamber.
- the other part of the rinsing liquid passes through the second inlet to the component to be cleaned, in which case optionally further elements, such as means for influencing the flow and / or a distribution system, may be interposed.
- This proportion of the rinsing liquid passes into the depot after rinsing of the component to be cleaned.
- Depot and sensor chamber according to the invention separated by structural or constructive measures, so that the sensor chamber is disposed outside the depot. This means that the sensor chamber and depot form two separate chambers, each of which can receive rinsing liquid.
- the level sensor is arranged according to the invention in the sensor chamber, so a contact of the sensor with the polluted flushing liquid located in the depot can be easily avoided without the risk of clogging a screen to protect the sensor.
- additional cleaning measures of the sensor such as rinses, unnecessary.
- the sensor chamber is hydraulically communicating with the depot via an opening system.
- the type of opening system in particular the shape, number and size as well as the arrangement pattern of the openings, is not limited according to the invention.
- it may be one or more circular openings, such as e.g. Boreholes, act in a common partition between depot and sensor chamber.
- a partition with the opening system may also be arranged in a connecting channel between the sensor chamber and the depot or between the sensor chamber and a connecting channel to the depot or between the depot and a connecting channel to the sensor chamber.
- supply system and opening system according to the invention are designed so that per unit time, a larger volume of the rinsing liquid can flow into the sensor chamber via the first inlet than can flow out of the sensor chamber through the opening system in the depot.
- the level in the sensor chamber does not decrease, as long as flushing liquid is supplied further into the sensor chamber.
- a corresponding configuration of supply system and opening system can be achieved, for example, in that the cross-sectional area of the first inlet leading to the sensor chamber is greater than the sum of the areas of all openings of the opening system.
- the cleaning device is also designed so that when filling the level of the rinsing liquid has reached at least a height in the sensor chamber, which corresponds to the upper limit of the opening system before the level of rinsing liquid in the depot has reached a level that the lower limit of Opening system corresponds. In the following, this is also referred to as "preferred filling" of the sensor chamber.
- such a preferred filling of the sensor chamber with rinsing liquid can be achieved in various ways, this is not restricted according to the invention.
- this can be done by a corresponding design of the supply system and / or by a corresponding dimensioning of depot and sensor chamber and / or by an appropriate dimensioning of the flowed through by the flushing liquid components of the cleaning device until this depot or sensor chamber.
- the rinsing fluid can travel a longer distance from the supply line to the depot floor compared to the path from the supply line to the sensor chamber floor.
- the depot may have a greater base area than the sensor chamber, so that a higher fill level is achieved more quickly in the sensor chamber.
- the bottom of the depot can be arranged in the dryer lower than the bottom of the sensor chamber.
- the preferred filling of the sensor chamber causes, in particular in connection with the fact that the inlet to the sensor chamber is greater than the drain, that the rinsing liquid from the beginning through the opening system always flows from the sensor chamber into the depot and not vice versa.
- no polluted flushing liquid penetrates from the depot into the sensor chamber when the level in the depot reaches or exceeds the height of the opening system, since the level in the sensor chamber by the measures already at least at the same level as in the depot or the Sensor chamber is even completely filled.
- the rinsing liquid can be removed only on the expiration of depot from the cleaning device according to the invention, the flow direction of the rinsing liquid is guaranteed by the sensor chamber via the opening system in the depot even after completion of Spül thoroughlykeitszuschreib.
- the flushing liquid located in the sensor chamber can only flow into the depot via the opening system when the fill level in the depot falls below at least the height of the upper boundary of the opening system. After completion of the rinsing liquid supply, this is generally achieved only by removal of the rinsing liquid over the course of the depot.
- the duration At of the flushing liquid contact of the sensor in the sensor chamber ends when, after the end of the flushing liquid feed, the fill level in the depot drops below a certain minimum level.
- This minimum dimension is dependent, for example, on the total quantity of rinsing liquid supplied, on the quantity of rinsing liquid supplied per unit time and / or on the dimensioning and / or arrangement of the depot, the sensor chamber and in particular the opening system.
- This type of hydraulic communication between the sensor chamber and the depot via the opening system thus allows, for example, that the duration At of the flushing liquid contact of the sensor in the sensor chamber varies depending on the flow rate of the flushing liquid from the depot and thus it can be determined how quickly the flushing liquid is removed from the depot ,
- a preferred filling of the sensor chamber ie a filling in which the level of the rinsing liquid in the sensor chamber has reached at least a height corresponding to the upper limit of the opening system, before the level of the rinsing liquid in the depot a height has reached the lower limit of the Opening system corresponds, made possible by the invariable geometry of the supply system.
- the fixed geometry of the delivery system herein means the sizing and placement of the corresponding channel or channels of the delivery system. This includes permanent cross-sectional constrictions or extensions of the channels of the supply system. For example, a corresponding dimensioning of the cross section may allow a preferred filling of the sensor chamber in that the first inlet has a larger cross section than the second inlet. Furthermore, the second feed may be longer than the first feed. In addition, an exploitation of gravity in the supply system can allow a preferred filling of the sensor chamber.
- a supply system with a common supply line to the first and the second inlet is very particularly preferred, the first inlet leading to the sensor chamber in a substantially vertical direction downwards, and the second inlet leading in a substantially horizontal direction to the component or components to be cleaned .
- a valve can also be provided in the supply system, for example, which is closed initially and is opened only after the preferred filling of the sensor chamber, in order to release the second feed to the cleaning component.
- the design of the invariable geometry of the supply system has the advantage that possible sources of error are kept low.
- the opening system is arranged at a distance from the depot floor in the vertical direction. This means that the lower limit of the opening system does not end directly with the depot floor.
- a certain amount of rinsing liquid can flow into the depot via the component to be cleaned without the level of the infused rinsing liquid reaching the height of the opening system.
- the flow direction of the rinsing liquid is advantageous influences the opening system from the sensor chamber to the depot and prevents the sensor from being contaminated.
- the cleaning device has a distribution system for the rinsing liquid, which is arranged in the flow direction of the rinsing liquid in front of the component to be cleaned.
- a distribution system is usually arranged above the component to be cleaned and causes a distribution of the washing liquid over the component to be cleaned, for example, a uniform distribution of the washing liquid is desired.
- the distribution system can be, for example, a diffuser, as described for example in DE 10 2009 046 683 A1.
- This diffuser has a distribution channel extending over its width for distributing the rinsing liquid introduced into the diffuser and an overflow channel coupled in fluid communication with the distribution channel, with which the rinsing liquid can be conducted downwards in the vertical flow direction to the component.
- the depot has a depot cleaning system for cleaning the rinsing liquid from soiling, in particular fluff.
- This depot cleaning system may be, for example, a sieve, a sieve cloth, a sponge, gauze, etc.
- the depot cleaning system is arranged on or directly above the bottom plate of the depot.
- the depot cleaning system is preferably removable and particularly preferably designed as an exchangeable filter bag or replaceable filter box.
- the depot corresponds to the condensate tray.
- Such advantageous condensate trays which simultaneously serve as depots, ie as collecting containers for the rinsing liquid, and which have a depot cleaning system, are described, for example, in WO 2010/028992 A1, in DE 10 2009 047 155 A1 and in DE 10 2010 039 603 A1 .
- the cleaning device according to the invention has a pump, with the rinsing liquid can be supplied to the supply system again. This has the advantage that the rinsing liquid can be used several times.
- rinsing liquid which has already been used be cleaned before it again enters the supply system of the cleaning device.
- This cleaning of the rinsing liquid can be done for example by a lint filter or a lint filter.
- the thus purified rinsing liquid can be fed back to the supply system, for example by means of a pump.
- a lint filter outside the depot for example, between depot and a pump, be mounted in front of a washing and / or before the supply system of the cleaning device.
- the cleaning device according to the invention is connected to a rinsing container for the storage of lint-free rinsing liquid.
- the rinsing liquid passes from the rinsing container into the supply system of the cleaning device.
- Lint-free rinsing liquid herein means, for example, fresh water from a water supply, optionally purified condensate and / or already rinsed washing liquid. Accordingly, lint-free rinsing liquid already reaches the rinsing container and / or the rinsing container itself contains a corresponding cleaning system, for example a lint filter, which is arranged in particular in the inlet region of the rinsing container. In this way, it is ensured that the rinsing liquid stored in the rinsing container is lint-free and thus lint-free rinsing liquid is used during a cleaning process.
- the rinsing container can also be part of a larger collecting container for aqueous liquid, in which case the portion of the collecting container containing the rinsing liquid can also be referred to as rinsing chamber. If this is the case of washing containers, both options should be covered.
- the rinse tank can be fixed or removable in the dryer.
- the rinsing container for the aqueous rinsing liquid optionally used in the dryer according to the invention preferably comprises a lower container opening and is connected by the latter to the supply system of the cleaning apparatus.
- the washing compartment is mounted in the dryer above the component to be cleaned.
- rinsing liquid can, by utilizing gravity, for example via a downpipe, flow into the cleaning device and a particularly good cleaning effect on the component to be cleaned can be achieved by the resulting pressure.
- condensate and / or already used rinsing liquid it is usually funded by a pump in the washing.
- no separate rinsing container can be provided in the inventive cleaning device and, for example, the depot or a condensate tray serving as a depot serve as a container for storing the rinsing liquid.
- the depot or the condensate tray contains a depot cleaning system.

- the invention also relates to a method for cleaning a arranged in a process air cycle of a dryer component with a rinsing liquid, wherein a cleaning device of the dryer a depot for receiving the rinsing liquid after their contact with the component to be cleaned and a sensor chamber in which a level sensor is arranged , Wherein the sensor chamber outside of the depot and with this via an opening system is arranged hydraulically communicating and a supply system of Cleaning device has a first inlet directly to the sensor chamber and a second inlet to the component to be cleaned, wherein
- a larger volume of the rinsing liquid flows into the sensor chamber via the first inlet as can flow out of the sensor chamber through the opening system in the depot;
- a level of the depot is determined.
- a rinsing liquid feed into the supply system of the cleaning apparatus takes place into the sensor chamber and another part of the rinsing liquid passes through the second inlet into the depot.
- the inflow of flushing fluid into the sensor chamber is greater than the outflow from the sensor chamber and, moreover, a preferred filling of the sensor chamber takes place, ie, when filling, the level of the flushing fluid in the sensor chamber has reached at least one height that corresponds to the upper limit of the opening system before the level of rinse liquid in the depot has reached a level corresponding to the lower limit of the opening system.
- a level in the sensor chamber is usually reached after triggering the cleaning process after a relatively short time, which allows contact of the level sensor with the rinsing liquid. This period of time from the triggering of the cleaning process to the contact of the sensor with flushing liquid at the time of installation generally depends on system-immanent variables such as the design of the cleaning device.
- this period varies At Bef üiiung with repeated cleaning processes in the same dryer usually do not.
- an amount of rinsing liquid is used which is sufficient to clean a component which is to be cleaned, at least on average, with lint.
- such an amount of rinsing liquid is also sufficient so that the opening system and the sensor are covered with rinsing liquid in a cleaning method according to the invention at maximum level in the sensor chamber F maxSe ns.
- such an amount of rinsing liquid is also sufficient to achieve a theoretical maximum filling level in the depot FthmaxDe ot in a cleaning method according to the invention, in which at least one height that corresponds to the lower limit of the opening system would be exceeded - if no rinsing liquid is removed from the depot would. Accordingly, the actual maximum level in the depot
- the actual maximum level in the depot FmaxDepot does not reach the level corresponding to the lower limit of the opening system.
- the same dryer neither the period from the initiation of the cleaning operation until the contact of the sensor with rinsing liquid Be At philiiung nor the duration of At-i of the contact of the level sensor with the washing liquid varies.
- the latter is due to the fact that the drainage of the rinsing liquid from the sensor chamber into the depot can take place unhindered during the entire cleaning process, since the fill level in the depot does not reach the opening system.
- Such unimpeded outflow thus depends only on system-immanent variables such as the design of the cleaning device or the amount of flushing liquid used.
- the duration At of the contact of the filling level sensor with flushing liquid corresponds to a value At-i, which is predetermined for a particular dryer with the same amount of flushing liquid, then it can be concluded that the actual maximum level in the depot F maxDe pot has not reached the height that corresponds to the lower limit of the opening system.
- the actual maximum level in the depot F maxDe pot exceeds the height corresponding to the lower limit of the opening system, wherein the level in the depot does not fall below this level again.
- the duration At 2 of the contact of the filling level sensor with rinsing liquid in this case approaches infinity.
- the cleaning method in this case provides a "time-ouf" function. This means that if the duration At 2 of the contact of the filling level sensor with rinsing liquid exceeds a certain set value, approximately 15 minutes, it is assumed that the level in the depot does not drop any further.
- the duration At of the contact of the filling level sensor with rinsing liquid corresponds to a value At 2 .
- the time-out value is reached, preferably the user a corresponding message displayed.
- the actual maximum level in depot F maxDe pot In a third case exceeds in a cleaning process, the actual maximum level in depot F maxDe pot initially the height corresponding to the lower limit of the opening system, however, the level drops in the depot even before reaching the time-out again, for example after completion of the rinsing liquid ,
- the duration At 3 of the contact of the level sensor with rinsing liquid of the duration At F De ot in which the level in the depot exceeds the height corresponding to the lower limit of the opening system. Only after the level falls below this level, the rinsing liquid from the sensor chamber can flow unhindered into the depot.
- the value of At 3 is generally between At-i and At 2 .
- the actual maximum level in depot F maxDe pot initially exceeded the height that corresponds to the lower limit of the opening system, but then has fallen again.
- a sustained low level which does not reach the height of the lower limit of the opening system at At-i, a first higher, but then again sinking level at At 3 and a constantly high level at At 2 .
- a malfunction of the cleaning device can be detected if, after a single triggering, the sensor was in contact with flushing fluid for a period of time At-i or At 3 and renewed contact of the sensor with flushing fluid takes place without renewed triggering of a cleaning operation. This would indicate that rinse fluid has entered the sensor chamber from the depot and could contaminate the sensor.
- the depot has a depot cleaning system for cleaning the rinsing liquid from soiling, in particular lint, and after contact of the rinsing liquid with the component to be cleaned, the depot cleaning system purifies the rinse liquid from soiling, in particular from lint.
- the depot cleaning system purifies the rinse liquid from soiling, in particular from lint.
- This can be done for example by the arrangement of a lint filter in the depot, so that the rinsing liquid must pass through the lint filter before it is removed via the expiry of the depot.
- a cleaning of the rinsing liquid it can then be supplied, for example via a pump, to the supply system of the cleaning device, either directly or via a rinsing container for storing the rinsing liquid.
- the rinsing liquid comprises condensate and a condensate tray at the same time serves as a depot.
- the rinsing liquid or the condensate is passed into the cleaning device and subsequently collected in the condensate tray after use and cleaned via a depot cleaning system located therein, such as a lint filter, and then pumped back into the supply system of the cleaning device.
- the flow rate of the rinsing liquid from the depot is determined on the basis of the duration ⁇ t of the contact of the filling level sensor with rinsing liquid.
- the duration At of the covering of the sensor with rinsing liquid during the cleaning process depends not only on system-internal sizes of the cleaning device, which do not change over time, such as the dimensioning and arrangement of the components of the cleaning device, substantially from the flow rate of the rinsing liquid from the Depot off.
- the flow rate may change, mainly because of the entrained in the used rinse liquid lint.
- a slowing down of the discharge rate in comparison to the discharge rate of lint-free rinsing liquid indicates a contamination or leaching of the depot, in particular of the depot outlet.
- this is displayed to the user so that he can make a corresponding cleaning or the dryer has internal cleaning agents that initiate a corresponding cleaning at a certain, determinable by this method pollution.
- the degree of soiling of the depot cleaning system is determined on the basis of the duration ⁇ t of the contact of the filling level sensor with rinsing liquid. Since a contamination or leaching of such a depot cleaning system leads to a slowing down of the drainage speed, the duration At of the contact of the sensor with the flushing liquid allows a statement about the leaching state of such a depot cleaning system.
- the depot cleaning system prevents leaching at the outlet of the depot, so that the duration ⁇ t can be directly related to the leaching state of the depot cleaning system.
- the user is displayed when a purge of the Depot cleaning system is to make or that, for example, interchangeable filter bags or boxes, they must be replaced.
- the rinsing liquid comprises condensate and at the same time serves as a depot for a condensate tray and has a depot cleaning system.
- a flow rate of the flushing liquid from the depot and / or a degree of soiling of the depot cleaning system is determined based on the duration ⁇ t of the contact of the level sensor with flushing liquid, this implies herein that an implicit determination of the depot level is included, even if these is not made in an explicit process step.
- the controller of the dryer can perform automatic cleaning even at nighttime if the user does not use the dryer anyway.
- the dryer can indicate an imminent cleaning phase and possibly inform the user that, for example, a condensate container used as a depot and / or rinsing container should not be emptied, so that sufficient condensate is available for cleaning with the cleaning device.
- the invention has the advantage that the depot level in a cleaning device of a dryer can be determined in a simple manner to prevent overflow of the depot.
- a high cleaning effect on the component to be cleaned can be ensured, since it can be prevented that in particular the lower part of the component to be cleaned with the soiled washing liquid remains in contact due to lack of drainage.
- a reduction of the maintenance effort is achieved by the invention, since contamination of the sensor with the dirty rinsing liquid in the depot is avoided in a simple manner, without the risk of clogging a screen to protect the sensor.
