After cleaning lint filter and/or vaporizer, the liquid with lint was collected in a catch tray before it is pumped in eluant container。Due to the lint in liquid, the operation of pump is still easily disturbed。In order at least make the lint accumulated by cleaning lint filter not arrive in catch tray, it is provided with the second lint filter。

Document EP2075368A1 relates to a kind of method, for removing the condensed fluid in the home appliances for nursing washings, wherein, the condensed fluid accumulated in the operation of this home appliances is collected in a collection container, wherein, the thing position of the condensed fluid being collected in collection container is monitored and produces the signal as the prompting for performing condensed fluid reset procedure when it is more than a thing position threshold value or starts condensed fluid reset procedure。

The task of the present invention is in that, it is provided that a kind of make washings process utensil, probability that especially washings drying appliance runs more reliably。

This task processes utensil also by a kind of washings and solves, and has the screen holder for receiving filter screen, and wherein, at least one is attached to this screen holder for the level measurement device measuring at least one height of water level in this screen holder。

This washings processes utensil and has the advantage that, i.e. can detect the degree that the filter screen being arranged in screen holder is filled with lint, hair etc. in a straightforward manner。At this, this washings processes utensil and uses the fact that, i.e. being present in lint in filter screen etc. more many, the liquid flowing to filter screen more is difficult to again flow out。Words sentence is talked about, and filter screen blocks more many with lint, more few by measuring by the liquid of this filter screen。That is, if liquid stream and thus also flows in filter screen installed therein in screen holder, then the liquid level in screen holder raises。More many lints have accumulated in filter screen, and liquid can maximum rise more high。Especially can detect a water level, the lint amount in this water level indicating filter screen by means of level measurement device, this lint amount is full of by lint corresponding to filter screen or is almost full with (below also referred to as " limiting water level ")。It is full of thus, it is possible to release filter screen by simple level gauging with lint etc.。

The particularly simple preferred configuration of one for level gauging a, it is possible to level transducer is arranged on the inner side of wall of screen holder。If water level rises until the height of this level transducer, this level transducer sends signal。

Also having a kind of preferred configuration is screen holder be connected with an overflow cavity according to connection container principle, and arrange and arrange that at least one is used for measuring the level measurement device of at least one height of water level of this overflow cavity。This configuration has the advantage that, i.e. mistake can carry out level measuring especially less。So, for instance hydrodynamic characteristics (wave is formed, rocks etc.) only occurs damply in overflow cavity。Also avoid owing to liquid splash causes the error detector of level measurement device。Can also avoid owing to the filter screen of infiltration causes the error detector of level measurement device。

A kind of special preferred configuration is, this overflow cavity has pass through openings near the end being arranged in this overflow cavity, bottom, and this overflow cavity is connected by the pass through openings of this bottom with screen holder on liquid stream。So can also reliably detect low water level。

It is possible that overflow cavity is in screen holder separately, and such as hydraulically it is connected with this screen holder by least one fluid passage (pipe, flexible pipe etc.)。

But, a kind of for compact and firmly mounting means and preferably configuration be that overflow cavity is arranged in screen holder。Thus, overflow cavity is integrated in screen holder。

In order to make overflow cavity do not blocked by lint, hair or other granule, it is preferable that overflow cavity is arranged in outside the region arranged to receive filter screen inside screen holder。

For the same purposes, it is preferable that overflow cavity is arranged in the side in the region arranged to receive filter screen。

Screen holder especially can be divided into the filter screen reception cavity being used for receiving filter screen and an overflow cavity, and wherein, the two chamber is separated from each other by a partition wall。This partition wall can have one for exchanging liquid, bottom pass through openings。By the pass through openings of this bottom, liquid can from filter screen stream to overflow cavity in, until in filter screen reception cavity and (level) liquid level in overflow cavity reach identical height, otherwise, then again flow back in filter screen when water level decreasing in filter screen reception cavity。Partition wall can have one for exchange of air, top venting opening, to avoid air trapping in overflow cavity。

Also having another kind of preferred configuration is that this overflow cavity has the overfall or overflow channel that lead at least one humidity sensor。Overfall be arranged in overflow cavity spilling opening (with its lower limb) be arranged on one and be equivalent on the height of limiting water level。If liquid reaches this water level, liquid flows at least one humidity sensor by this overfall, and this humidity sensor can export corresponding signal when being wet。Here, level measurement device such as can include overfall and humidity sensor。This improvement project has the advantage that, i.e. sensor (humidity sensor etc.) originally can be arranged dividually with overflow cavity。So, sensor can be readily replaced, it is also possible to provides enough loading spaces for sensor。

Similarly, without arranging special overflow cavity, it is also possible to overfall is set directly in screen holder or in screen holder。

Also having a kind of preferred configuration is be at least partially disposed in overflow cavity by least one humidity sensor。This is capable of particularly compact version。This at least one humidity sensor is disposed so as it and sends signal when reaching at least one limiting water level。

Also having a kind of preferred configuration is that level measurement device and controls device and functionally connects, and wherein, this control device is arranged to, and at least one based at least one level measurement device described is measured and triggered washings and process at least one action of utensil。

This at least one action can include output acoustical signal and/or optical signalling。This at least one action can also include exporting a prompting to user, particularly by the display unit of home appliances。This at least one action can also include closing home appliances and/or forbidding certain process flow of subsequent start-up, especially washings handling process。

Also having a kind of preferred configuration is be at least partially disposed in overflow cavity by multiple humidity sensors, and the different water levels of the liquid in overflow cavity are reacted by these humidity sensors。

As such, it is possible to the action according to the water level triggered fraction reached respectively by means of humidity sensor。But home appliances such as can the first humidity sensor bottom water level is reached the second higher water level of reacting not yet be reached time, give a warning to user, for instance the form of " lint filter screen is full of, and please change/clean "。If therefore the second humidity sensor reaching the second higher water level and correspondence reacts, such as can additionally or alternatively stop new washings handling process, there is the message of " equipment is closed, because lint filter screen is full, please change " form if desired simultaneously。

Alternatively, for instance can by means of single level measurement device, such as detect different water levels by means of float。

A kind of preferred configuration is that level measurement device has at least one humidity sensor。This humidity sensor such as can have an electrode pair。This electrode is to being such as under voltage for humidity detection, wherein, if the intermediate space between two electrodes is liquid filled, just the electric current then flow through between electrodes raises or formed。Curent change can be detected and well for water-level detecting。In other words, electrode is to being checked its conducting value by (digitally or similarly)。

Alternatively, or additionally, level measurement device can have a float being arranged in overflow cavity, this float and a paillon foil sensor (Reed-Sensor) or Foil switches (Reed-Schalter) couples or has this device。

Filter screen can be such as filter screen or filter。Screen holder can also correspondingly be referred to as filter mounting etc.。Filter screen or filter such as can be made up of metal or fabric。

Liquid can be water, especially condensed water。

Especially from lint filter screen and/or heat exchanger, cleaning water can be guided to screen holder。

Washings processes utensil and could be arranged to, and level measuring (only) performs relevantly with the cleaning process of lint filter screen and/or heat exchanger or deposits with an action。So, the water level caused owing to the flush volume to determine promptly is full of can be detected, and this produces high determination precision。Conversely, because the water level relevant with washings volume and the moisture content that is stored in washings beyond and the water level that causes beyond being left in the basket。

It especially can be washings drying appliance, especially washings exsiccator or (being synthesized by washing machine and washings dryer group) washing exsiccator that washings processes utensil。

This task solves also by a kind of method, for determining that washings processes predetermined (with lint) compactedness of the lint filter screen of utensil, wherein, the method at least comprises the following steps: (i) is with pouring liquid or rinses described lint filter screen；(ii) determining that the liquid in this lint filter screen reaches predetermined (liquid) water level, this water level is corresponding to predetermined compactedness。That is, the method utilizes water level to determine as the tolerance for compactedness。Association between water level and compactedness such as can be passed through to attempt or empirically determine。

A kind of preferred configuration is, it is determined that the step reaching predetermined water level includes determining a persistent period, keeps reaching this predetermined water level within this persistent period。In other words, it is possible to a previously given persistent period, (or exceeding) predetermined water level height must be reached in this persistent period, in order to for drawing or consider the determination of compactedness, for instance be used for triggering an action。This persistent period such as can be saved in control device。This configuration has the advantage that, i.e. can ignore the short-term water-level fluctuation that such as can cause owing to wave is formed, and only consider " static state " height of water level。

Also a kind of preferred configuration is, by means of the liquid wash lint filter screen to have predetermined volume to carry out the determination of predetermined water level or to conclude。In such manner, it is possible to realize associating accurately especially between water level and compactedness。

A kind of special preferred configuration is, rinses lint filter screen to carry out the determination of predetermined water level by means of with the liquid from the cleaning process of (particular in process gas passage) lint filter screen of upstream and/or heat exchanger。Utilizing at this, the volume for the liquid of the lint filter screen and/or heat exchanger that clean upstream is known well。Such as can pass through to empty the eluant container (insurgently) with known volume to provide liquid。Because this cleaning process can also be periodically executed, then can also not or only have little additional expense ground and regularly determine the compactedness of lint etc.。

A kind of preferred improvement project is to perform the step of an action in the followed by positively determining the step reaching predetermined water level。

In figures in the following, it is more fully described the present invention by the embodiment being shown schematically in the figures。At this, it is possible to represent identical for clarity with identical reference marker or act on identical element。Accompanying drawing illustrates:

Fig. 1 illustrates that the washings being configured as washings exsiccator processes the sketch of utensil；

Fig. 2 process according to the washings of the first embodiment the screen holder of utensil side cutaway view and

Fig. 3 processes the side cutaway view of the screen holder of utensil according to the washings of the second embodiment。

As shown in Figure 1, washings processes utensil, be washings exsiccator 1 here, and including the hothouse 2 being configured as rotatable cylinder, this hothouse receives the article of humidity, is washings 3 here, is used for drying。Arranging the process gas guiding device (Prozessluftfuehrung) 4 of a closing, in this process gas guiding device, process gas stream drives circulation by aerator 5, and this process gas stream absorbs and discharges the moisture content from washings 3。Process gas is heated in thermal source 6 before entering in hothouse 2。So heated process gas streams when absorbing moisture content after dropping on the washings 3 of surrounding in the drying chamber due to the rotation of hothouse 2, leaves hothouse 2 and arrives heat sink 7。Here process gas is cooled, thus the moisture content carried is condensed out, the condensed fluid as liquid form is deposited in the structure of heat sink 7, and drips in the catch tray 8 being arranged in this heat sink lower section。This condensed fluid out arrives catcher 11 through pump conduit 9 (condensate pump 10 is joined to this pump conduit) from catch tray 8。This catcher 11 of such configuration so that this catcher can take out after dry run terminates from exsiccator 1, in order to pours out liquid from catcher and carries out suitable cleaning。

Between hothouse 2 and heat sink 7, process gas guiding device 4 is provided with the first lint filter 12。This first lint filter 12 is necessary, to intercept and capture the lint (these lints are fiber grain trickle, dust form and analog) that obtains from washings 3 of process gas of flowing, thus these lints do not arrive heat sink 7 and to pollute this heat sink。Why needing so, the lint being primarily due to be deposited on the surface correspondingly exposed of heat sink 7 can make the capacity of heat transmission of the structure within heat sink 7 significantly be deteriorated, consequently, it is possible to damage or even jeopardize the operation of exsiccator 1。Certainly, the existence in process gas guiding device 4 of first lint filter 12 is not also from possible infringement, because if it is blocked by lint in the operating of dry run, the first lint filter 12 also results in the significant flow obstacle in process gas guiding device 4 in some cases。

In order to avoid this infringement, and also realize removing the physical possibility of lint from exsiccator 1, by the first cleaning device 13,14,15 are attached to the first lint filter 12, the first lint filter 12 can be made to break away from lint when using the condensed fluid being stored in catcher 11 by these first cleaning devices。For this, catcher 11 is connected the first flushing line 13, this first flushing line arrives the first allotter 15 being arranged in the first lint filter 12 by the first controlling organization 14, condensed fluid from catcher can pass through this first allotter and distribute in the first lint filter 12, thus, this condensed fluid absorbs and discharges the lint accumulating in the first lint filter 12。This condensed fluid with lint loading arrives the second lint filter 28 by discharger 16, this the second lint filter intercepts and captures the lint absorbed from condensed fluid, then condensed fluid flows to again catch tray 8, in order to be transmitted back to catcher 11 from this catch tray by means of condensate pump 10。In the second lint filter 28, lint accumulates as close, moist agglomerate, and this agglomerate can relatively easily be taken out and cleaning from the second lint filter 28。Alternatively, lint filter 28 can be removable。

Thermal source 6 and heat sink 7 is integrated in heat pump 6,7,20,21,22 in currently shown embodiment, and in these heat pumps, the heat extracted from process gas in heat sink 7 is supplied to again process gas by pump heat source 6 and at this thermal source。For this, the refrigerant loop 20 of employing one closing, cold-producing medium circulates in this refrigerant loop。Cold-producing medium refer to can for pressure and temperature suitable when reversibly evaporation and condensation material。This material can be the Hydrocarbon of propane, carbon dioxide or fluoride, for instance known R134a, R152a, R407C and R410a, wherein, last-mentioned two kinds of materials are the mixture of the Hydrocarbon of multiple fluoride。Under any circumstance, the cold-producing medium in refrigerant loop 20 arrives heat sink 7 in fluid form, and at heat sink place, it evaporates when hot in absorbing the process gas that also flows through。Compressor 21 in refrigerant loop 20 compresses the cold-producing medium evaporated and cold-producing medium heat source 6 is carried。Cold-producing medium liquefies at this place, and its mode is, heat is released to the process gas flowed through by it。Now, cold-producing medium flows to reducer 22 (being represented by valve, capillary tube or choke block), the pressure that it is here lowered by pressure release in fluid form in refrigerant loop 20。Cold-producing medium returns arrival heat sink 7 in this form, in order to again evaporate at this place。Refrigerant loop 20 must completely enclose, to guarantee completely enclosed cold-producing medium in the expection service life of exsiccator 1。

It practice, the first lint filter 12 can not fully absorb the lint carried by process gas；Always want it is considered that its trickle part of lint pole successfully passes lint filter 12, and do not intercepted and captured by it。Then these trickle lints are deposited in heat sink 7 more or less completely, and wherein, the condensed fluid occurred at this place can make lint be attached on the surface correspondingly exposed of heat sink 7。These lints (if desired the repeatedly dry run in exsiccator 1) are likely to significantly damage the function of heat sink 7。Current difficulty is in that, owing to needs fully seal refrigerant loop 20, it is impossible that the purpose in order to clean is taken out heat sink 7 from exsiccator 1。Therefore, the second cleaning device 23,24,25 is attached to heat sink 7, by these second cleaning devices can also be used in catcher 11 collect condensed fluid, in order to clean the surface being exposed to process gas of heat sink 7 and remove the lint of accumulation。For this, the second flushing line 23 is appended on this catcher together with the second controlling organization 24 engaged, catcher 11 is connected by this second flushing line with the second allotter 25 being positioned on heat sink 7。By this second allotter 25, condensed fluid arrives heat sink 7 from catcher 11, and can clean the lint being deposited on heat sink place。Condensing droplet such, that load with lint is fallen in catch tray 8, and carries from catch tray to catcher 11 again by means of condensate pump 10。Because the first lint filter 12 intercepts and captures the major part of all lints, heat sink 7 loads only fewerly, and the lint being deposited in heat sink place is relatively trickle。As time goes on these lints, especially hair still can especially damage condensate pump 10。Therefore, from heat sink 7, the condensed fluid of drippage is also directed at the second lint filter 28。

Controlling organization 14 and 24 is currently denoted respectively as simple valve 14 or 24。When wishing relatively strong condensate flow for corresponding cleaning purpose, it is possible to be additional to each this valve 14 or 24 and a pump is set。A unique pump can also be attached to two valves 14 and 24 if desired。

Exsiccator 1 is provided with control device 26。This control device serves the user of exsiccator 1, for selecting a program for desired dry run from multiple provided programs, this control device comprises for making user see the display device of necessary information, and also controls all controlled parts of exsiccator 1。For clarity, it is shown without in FIG controlling circuit accordingly。

Lint filter 28 is arranged in the screen holder 27 of tank shape。Use for cleaning the first lint filter 12, drip due to cleaning in the condensed fluid Kf of the lint that adulterates and heat sink 7 from properly functioning, the condensed fluid Kf of the lint that adulterates is flowed into as in entrance, the screen holder upper side opened wide by discharger 16。Condensed fluid Kr that purify by means of filter 28, that be substantially free of lint flows in catch tray 8 through the outlet 30 being arranged on bottom surface。The level measurement device 31 being used for measuring at least one height of water level of screen holder 27 is attached to screen holder 27。Level measurement device 31 is connected with controlling device 26 by data wire 32, thus the measurement data produced by level measurement device 31 can be sent on control device 26 and can process further at this control device and/or use。If level measurement device 31 detects the predetermined condensed fluid water level in screen holder 27 or reacts to that, control device 26 and such as can trigger at least one action。

Fig. 2 is illustrated in detail in screen holder 27 as profile with side view。Screen holder 27 is configured to tank shape, and has unlimited upper side 29。The second lint filter 28 being such as also configured to tank shape can be loaded by unlimited upper side 29。At exsiccator 1 run duration, screen holder 27 and the second lint filter 28 are poured by the upper side 29 opened wide, or rather with from the condensed fluid Kf of heat sink 7 drippages and/or the condensed fluid Kf perfusion to be imported by discharger 16。Condensed fluid Kf is played the effect of flow resistance by the second lint filter 28, thus condensed fluid Kf to be clean accumulates in screen holder 27 and neutralizes in the second lint filter 28。Thus, condensed fluid Kf has water level P in screen holder 27。Accumulating in lint in the second lint filter 28 etc. more many, water level P can temporarily rise more high。Especially when cleaning the first lint filter 12 and/or when cleaning heat pump, it is possible to make the condensed fluid volume determined arrive especially insurgently in screen holder 27 in the short time by open control mechanism 14,24。At this moment, the maximum stage P being temporarily reached can be counted as the tolerance of the filling of the second lint filter 28, improve because of the quantity that first flow resistance of the second lint filter 28 increases along with lint etc., and secondly lint etc. occupies bigger volume in the second lint filter 28。Thus, water level P can be associated with the compactedness in the second lint filter 28 such as lint (at least when being carried out)。

Screen holder 27 is divided into one for receiving the filter screen reception cavity 27a and an overflow cavity (Flutkammer) 27b of the second lint filter 28。Filter screen reception cavity 27a and overflow cavity 27b is separated from each other by means of partition wall 33。Partition wall 33 has the pass through openings 34 of bottom, and the pass through openings of this bottom fluidly connects filter screen reception cavity 27a and overflow cavity 27b and is arranged at the end of overflow cavity 27b。By the pass through openings 34 of bottom, condensed fluid can flow overflow cavity 27b through the second lint filter 28 from filter screen reception cavity 27a, substantially reaches identical height until (level) the water level P in filter screen reception cavity 27a and overflow cavity 27b。Flow the condensed fluid in overflow cavity 27b without lint。On the contrary, when the water level P in filter screen reception cavity 27a declines, condensed fluid again flow back in filter screen reception cavity 27a from overflow cavity 27b。Partition wall 33 can also have for exchange of air, top venting opening 35, to avoid the air in overflow cavity 27b to gather。At this, venting opening 35 above this is constituted retaining wall 36, and to avoid dabbling, wave etc. pierced by the venting opening 35 of top。Thus, filter screen reception cavity 27a and overflow cavity 27b is linker。Water level P in filter screen reception cavity 27a is reflected in overflow cavity 27b。Partition wall 33 also makes, and the power behavior of the condensed fluid in filter screen reception cavity 27a is delivered on overflow cavity 27b with only weakening。

Overflow cavity 27b has tubular overfall 38 above the pass through openings 34 of bottom, and the end opened wide being passed in overflow cavity 27b of this overfall is constituted overflows opening 39。Overfall 38 is seen downward-sloping from overflow cavity 27b。Thus, if water level P is issued in the situation of limiting water level Pg or exceedes the edge overflowing opening 39, the condensed fluid being arranged in overflow cavity 27b is at least partially in spilling opening 39 and is flowed out by overfall 38。Humidity sensor 40 is led in the side deviating from overflow cavity 27b of overfall 38。If condensed fluid flows to humidity sensor 40 through overfall 38, then this sensor sends signal。Overfall 38 and humidity sensor 40 constitute level measurement device 38, and 40, this level measurement device sends signal when up to or over limiting water level Pg。Limiting water level Pg such as can second lint filter 28 corresponding to while cleaning (at least)。

Send signal (this can pass through data wire 32 controlled device 26 and identify) control device 26 by humidity sensor 40 (if desired on the predetermined persistent period) and at least one action can be triggered, for instance the operation of output warning prompt and/or closedown exsiccator。If when repeatedly successively, such as when the cleaning process mutually followed, humidity sensor 40 all sends signal every time or repeatedly, and controlling device 26 can also at this moment just trigger action。Have the advantage that outside humidity sensor 40 is arranged in screen holder 27, i.e. humidity sensor 40 can be replaceable and also can be according to circumstances freely directed。Overflow cavity 27b can also arrange multiple level measurement device 38,40, for instance arrange and go up at various height。

Fig. 3 illustrates the screen holder 41 according to the second embodiment as profile with side view, for instance this screen holder can be used to replace screen holder 27。Contrary with screen holder 27, screen holder 41 does not have overfall 38 now。More precisely, be provided with three electrodes 42a, 42b and 42c in overflow cavity 27b, these electrodes constitute two electrodes to 42a, 42b or 42b, 42c。If water level P (when limiting water level Pg1) reaches to terminate at mutually level first electrode to 42a, 42b, electric current between two electrodes 42a, 42b changes, and this can by controlling device 26 sensing (such as by electric current comparison means 43) directly or indirectly。Level measurement device such as can pass through three electrodes 42a, 42b and 42c and electric current comparison means 43 is constituted。

If water level P (when limiting water level Pg2) also reaches to be positioned at the 3rd electrode 42c of higher height, then the electric current between two electrodes 42b, 42c changes, and this also is able to be sensed directly or indirectly by control device 26。Thus, it is possible to sense two different water level P as limiting water level Pg1 and Pg2 by means of three electrodes 42a, 42b and 42c。Then control device 26 and such as can trigger different actions, the warning prompt of the such as output when reaching the limiting water level Pg1 of lower section " lint filter will be full; please change/clean " form, the warning prompt of output " lint filter is full, please change/clean " form and close exsiccator during limiting water level Pg2 above reaching。

Alternatively, it is also possible to only use an electrode pair, or can also use more than two, can also the electrode pair of differing heights。

Certainly, the present invention is not limited to shown embodiment。That is, screen holder 27 can also only by irrigating from the condensed fluid of heat sink 7 drippages。Such as can be filtered by means of the lint filter of oneself for the condensed fluid cleaned by the first lint filter 12, as shown in WO2010/028992A1。Screen holder 27 can also only irrigate with the condensed fluid flowed out from the first lint filter 12。Screen holder 27 then can undertake the function of such as the second lint filter shown in WO2010/028992A1。The shape of screen holder and filter screen is also not limited to shown shape。Filter screen and filter can removably use。
