Task of the present invention is, a kind of washed articles treater tool, possibility of moving more reliably of washings drying appliance especially of making is provided.
This task solves according to the feature of independent claims.Preferred embodiment especially can be drawn by dependent claims and following description.
This task also solves by a kind of washed articles treater tool, has for the filter screen acceptance division that receives filter screen, and wherein, at least one is used for the level measurement device of at least one height of water level on this filter screen acceptance division of measurement and is attached troops to a unit to this filter screen acceptance division.
This washed articles treater tool has advantage,, can survey the degree that the filter screen that is arranged in the filter screen acceptance division is filled with flock, hair etc. in simple mode that is.At this, the such fact of this washed articles treater tool utilization, that is, it is more many to be present in flock in the filter screen etc., and the liquid that flows to filter screen more is difficult to flow out again.The words sentence is talked about, and filter screen stops up more manyly with flock, and is more few by the liquid throughput of this filter screen.That is, if liquid flows in the filter screen acceptance division and also flows to thus in the filter screen that is installed in wherein, then the liquid level in the filter screen acceptance division raises.More many flocks have accumulated in the filter screen, and liquid can maximum rise more highly.Especially can survey a water level by means of level measurement device, the flock amount in this water level prompting filter screen, this flock amount is full of or almost is full of (below be also referred to as " limiting water level ") corresponding to filter screen by flock.Thus, can release filter screen by simple level gauging is full of with flock etc.
For a kind of simple especially preferred configuration of level gauging, a level transducer can be arranged on the inboard of wall of filter screen acceptance division.If water level rises up to the height of this level transducer, this level transducer sends signal.
Also have a kind of preferred configuration to be, according to the connection container principle filter screen acceptance division is connected with a spill cavity, and arrange and arrange that at least one is used to measure the level measurement device of at least one height of water level of this spill cavity.This configuration has advantage,, can mistake carry out level measuring that is especially less.Like this, for example hydrodynamic characteristics (wave forms, rocks etc.) only occurs in spill cavity damply.Also avoid because the liquid splash causes the error detector of level measurement device.Can also avoid because the filter screen that soaks into causes the error detector of level measurement device.
A kind of special preferred configuration is, this spill cavity has near a pass through openings end that is arranged in this spill cavity, the bottom, and the pass through openings of this bottom flows with the filter screen acceptance division this spill cavity and is connected at liquid.So also can survey low water level reliably.
Possible is, spill cavity be in the filter screen acceptance division separately, and for example hydraulically be connected with this filter screen acceptance division by at least one fluid passage (pipe, flexible pipe etc.).
Yet a kind of at compact and firm mounting means and preferably configuration is that spill cavity is arranged in the filter screen acceptance division.Thus, spill cavity is integrated in the filter screen acceptance division.
For spill cavity is not stopped up by flock, hair or other particle, preferably spill cavity is arranged in outside the zone that filter screen acceptance division inside arranges in order to receive filter screen.
For identical purpose, preferably spill cavity is arranged in the side in the zone that arranges in order to receive filter screen.
Especially the filter screen acceptance division can be divided into one for the filter screen reception cavity and the spill cavity that receive filter screen, wherein, these two chambeies are separated from each other by a partition wall.This partition wall can have one and be used for pass through openings exchanging liquid, the bottom.By the pass through openings of this bottom, liquid can flow to the spill cavity from filter screen, and (level) liquid level with in the spill cavity in the filter screen reception cavity is reached identical height, otherwise, when descending, the water level in the filter screen reception cavity then flow back in the filter screen again.Partition wall can have one and be used for venting opening exchange of air, top, to avoid air trapping in spill cavity.
Also have another kind of preferred configuration to be, this spill cavity has overfall or the overflow channel that leads at least one humidity sensor.Overfall be arranged in spill cavity the opening (with its lower limb) that overflows 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 exported corresponding signal when moistening.Here, level measurement device for example can comprise overfall and humidity sensor.This improvement project has advantage, that is, sensor (humidity sensor etc.) originally can be arranged dividually with spill cavity.Like this, sensor can easily be changed, and can also provide enough spaces of packing into for sensor.
Similarly, if special spill cavity is not set, also overfall can be set directly in the filter screen acceptance division or on the filter screen acceptance division.
Also have a kind of preferred configuration to be, at least one humidity sensor is arranged in the spill cavity at least in part.This can realize special compact structure form.This at least one humidity sensor is arranged like this, makes it send signal when reaching at least one limiting water level.

A kind of preferred improvement project is, follows after the step of predetermined water level is determined to reach in certainty ground and carries out a step of moving.
In following accompanying drawing, by the embodiment that schematically shows in the accompanying drawings the present invention is described in more detail.At this, can represent identical with identical reference marker or the effect components identical for clarity.Accompanying drawing illustrates:
Fig. 1 illustrates the sketch of the washed articles treater tool that is configured as the washings drier;
Fig. 2 according to the side cutaway view of the filter screen acceptance division of the washed articles treater tool of first embodiment and
Fig. 3 is according to the side cutaway view of the filter screen acceptance division of the washed articles treater tool of second embodiment.
As shown in FIG. 1, the washed articles treater tool is washings drier 1 here, comprises the hothouse 2 that is configured as rotatable cylinder, and this hothouse receives moist article, be washings 3 here, is used for drying.The process gas guiding device (Prozessluftfuehrung) 4 of one sealing is set, and in this process gas guiding device, process gas stream drives circulation by air blast 5, and this process gas stream absorbs and ejects moisture content from washings 3.Process gas was heated at thermal source 6 before entering into hothouse 2.Heated like this process gas streams owing to the rotation of hothouse 2 under the situation that absorbs moisture content and drops in hothouse after the washings 3 all around, leaves hothouse 2 and arrives heat sink 7.Here process gas is cooled, thereby the moisture content condensation of carrying, and is deposited on as the condensate liquid of liquid form on heat sink 7 the structure, and drips in the catch tray 8 that is arranged in this heat sink below.This condensate liquid comes out to arrive gatherer 11 through pump line road 9 (condensate pump 10 joins to this pump line road) from catch tray 8.This gatherer 11 of configuration makes this gatherer to take out from drier 1 after dry run finishes, in order to pour out liquid and carry out suitable cleaning from gatherer like this.
Between hothouse 2 and heat sink 7, in process gas guiding device 4, be furnished with the first flock filter 12.This first flock filter 12 is necessary, in order to intercept and capture the flock (these flocks are fiber grain trickle, dust form and analog) that process of flowing gas obtains from washings 3, these flocks do not arrive heat sink 7 and pollute that this is heat sink thus.Why needing like this, mainly is because be deposited on the capacity of heat transmission variation greatly that heat sink 7 the lip-deep flock that correspondingly exposes can make the structure of heat sink 7 inside, thereby may damage or even the operation that jeopardizes drier 1.Certainly, possible infringement is not avoided in first existence of flock filter 12 in process gas guiding device 4 yet, because if it is stopped up by flock in the running of dry run, the first flock filter 12 also causes the significant flow obstacle in the process gas guiding device 4 in some cases.
For fear of this infringement, and the physical possibility of flock is removed in realization from drier 1, with first cleaning device 13,14,15 attach troops to a unit to the first flock filter 12, can make the first flock filter 12 break away from flock under use is stored in the situation of the condensate liquid in the gatherer 11 by these first cleaning devices.For this reason, be connected first flushing line 13 at gatherer 11, this first flushing line arrives first distributor 15 that is arranged on the first flock filter 12 by first controlling organization 14, condensate liquid from gatherer can be distributed on the first flock filter 12 by this first distributor, thus, this condensate liquid absorption and discharge accumulate in the flock on the first flock filter 12.This condensate liquid that loads with flock arrives the second flock filter 28 by discharger 16, this second flock filter is intercepted and captured the flock that absorbs from condensate liquid, condensate liquid flows to catch tray 8 again then, in order to carry recovery storage 11 by means of condensate pump 10 from this catch tray.In the second flock filter 28, flock as closely, moist agglomerate accumulates, this agglomerate can relatively easily be taken out from the second flock filter 28 and cleaning.Alternatively, flock filter 28 can be for removable.
Be integrated into heat pump 6,7 among the embodiment of thermal source 6 and heat sink 7 shown in current, in 20,21,22, in these heat pumps, the heat of extracting from process gas in heat sink 7 is supplied to process gas again by pump heat source 6 and at this thermal source.For this reason, adopt the refrigerant loop 20 of a sealing, cold-producing medium circulates in this refrigerant loop.Cold-producing medium refer to can be under condition suitable with regard to pressure and temperature the material of evaporation and condensation reversibly.This material can be propane, carbon dioxide or the hydrocarbon of fluoridizing, known R134a, R152a, R407C and R410a for example, wherein, last-mentioned two kinds of mixtures that material is the multiple hydrocarbon of fluoridizing.Under any circumstance, the cold-producing medium in the refrigerant loop 20 arrives heat sink 7 with the form of liquid, at heat sink place, evaporate under the situation of its heat in absorbing the process gas of also flowing through.The cold-producing medium that compressor 21 compression in the refrigerant loop 20 is evaporated and cold-producing medium heat source 6 carried.Cold-producing medium is in this place's liquefaction, and its mode is that it discharges heat to the process gas of flowing through.Now, cold-producing medium flows to flow controller 22 (representing by valve, capillary or choke block), the pressure that it is lowered by pressure release to here with the form of liquid in refrigerant loop 20.Cold-producing medium with this form return arrive heat sink 7 so that at this place evaporation again.Refrigerant loop 20 necessary complete closed are to guarantee complete closed cold-producing medium in the expection service life of drier 1.
In fact, the first flock filter 12 can not absorb the flock that is carried by process gas fully; Always to consider that its trickle part of the flock utmost point is successfully passed flock filter 12, and not by its intercepting and capturing.These trickle flocks are deposited in heat sink 7 then more or less fully, and wherein, the condensate liquid that occurs at this place can make flock be attached on heat sink 7 the surface that correspondingly exposes.These flocks (passing through the repeatedly dry run in the drier 1 in case of necessity) may damage heat sink 7 function greatly.Current difficulty is that owing to need seal refrigerant loop 20 fully, it is impossible taking out heat sink 7 for the purpose that cleans from drier 1.Therefore, second cleaning device 23,24,25 is attached troops to a unit to heat sink 7, also can use the condensate liquid of in gatherer 11, collecting by these second cleaning devices, in order to clean heat sink 7 the surface that is exposed to process gas and remove the flock that accumulates., second flushing line 23 is attached troops to a unit to this gatherer together with second controlling organization 24 that engages, this second flushing line is connected gatherer 11 with second distributor 25 that is positioned on heat sink 7 for this reason.By this second distributor 25, condensate liquid arrives heat sink 7 from gatherer 11, and can clean deposition at the flock at heat sink place.Condensing droplet such, that load with flock is fallen in the catch tray 8, and 11 carries from catch tray to gatherer again by means of condensate pump 10.Because the first flock filter 12 is intercepted and captured the major part of all flocks, heat sink 7 loads only fewerly, and it is trickle relatively to be deposited in the flock at heat sink place.These flocks, especially As time goes on hair still can especially damage condensate pump 10.Therefore, the condensate liquid of drippage also is directed to the second flock filter 28 from heat sink 7.
Controlling organization 14 and 24 current simple valve 14 or 24 of being expressed as respectively.For for corresponding cleaning purpose and wish to have the situation of strong relatively condensate flow, can be additional to each this valve 14 or 24 pump is set.Also a unique pump can be attached troops to a unit to two valves 14 and 24 in case of necessity.
In drier 1, be provided with control device 26.This control device is served the user of drier 1, be used for selecting a program from a plurality of programs that provide at desirable dry run, this control device comprises be used to making the user see the display unit of necessary information and all controlled parts of control drier 1.For clarity, corresponding control circuit is not shown in Fig. 1.
Fig. 2 at length illustrates filter screen acceptance division 27 as profile with side view.Filter screen acceptance division 27 is configured to jar shape, and has unlimited upper side 29.Can pack into by the upper side 29 that opens wide and for example also to be configured to the second flock filter 28 of jar shape.At drier 1 run duration, filter screen acceptance division 27 and the second flock filter 28 are poured by the upper side 29 that opens wide, or rather with condensate liquid Kf and/or the condensate liquid Kf perfusion to import by discharger 16 from heat sink 7 drippages.28 couples of condensate liquid Kf of the second flock filter play the effect of flow resistance, thereby condensate liquid Kf to be clean accumulates in the filter screen acceptance division 27 neutralizations second flock filter 28.Thus, condensate liquid Kf has water level P in filter screen acceptance division 27.It is more many to accumulate in flock in the second flock filter 28 etc., and water level P can rise more highly in short-term.Especially when cleaning the first flock filter 12 and/or when cleaning heat pump, can make the condensate liquid volume of determining in the short time, arrive especially insurgently in the filter screen acceptance division 27 by open control mechanism 14,24.At this moment, the maximum stage P that temporarily reaches can be counted as the tolerance of the filling of the second flock filter 28, because the quantity that increases along with flock etc. of the flow resistance of the second flock filter 28 and improving at first, and secondly flock etc. occupies bigger volume in the second flock filter 28.Thus, (at least when cleaning) can associate the compactednesses in the second flock filter 28 such as water level P and flock.
Filter screen acceptance division 27 is divided into one for the filter screen reception cavity 27a and a spill cavity (Flutkammer) 27b that receive the second flock filter 28.Filter screen reception cavity 27a and spill cavity 27b are separated from each other by means of partition wall 33.Partition wall 33 has the pass through openings 34 of bottom, the pass through openings of this bottom fluidly connect filter screen reception cavity 27a and spill cavity 27b and be arranged in spill cavity 27b the end near.By the pass through openings 34 of bottom, condensate liquid can flow to the spill cavity 27b through the second flock filter 28 from filter screen reception cavity 27a, and (level) water level P with among the spill cavity 27b in filter screen reception cavity 27a reaches identical height basically.The condensate liquid that flows among the spill cavity 27b does not contain flock.On the contrary, when the water level P in filter screen reception cavity 27a descended, condensate liquid flow back into from spill cavity 27b among the filter screen reception cavity 27a again.Partition wall 33 can also have for venting opening 35 exchange of air, the top, to avoid the air accumulation among the spill cavity 27b.At this, the venting opening 35 of this top constitutes retaining wall 36, with avoid dabbling, wave etc. pierces by the venting opening 35 of top.Thus, filter screen reception cavity 27a and spill cavity 27b are linker.Water level P among the filter screen reception cavity 27a is reflected among the spill cavity 27b.Partition wall 33 makes that also the power behavior of the condensate liquid among the filter screen reception cavity 27a is delivered on the spill cavity 27b with only weakening.
Send signal (this can by the identification of data wire 32 controlled devices 26) control device 26 by humidity sensor 40 (in case of necessity on predetermined time duration) and can trigger at least one action, for example export warning prompt and/or close the operation of drier.If under the situation of cleaning process successively, that for example following mutually repeatedly, humidity sensor 40 all sends signal at every turn or repeatedly, control device 26 also can be at this moment trigger action.Humidity sensor 40 is arranged in outside the filter screen acceptance division 27 has advantage, that is, humidity sensor 40 can be changed simply and can be according to circumstances freely directed.On spill cavity 27b, also can arrange a plurality of level measurement devices 38,40, for example arrange and go up at various height.
Fig. 3 illustrates filter screen acceptance division 41 according to second embodiment as profile with side view, for example can use this filter screen acceptance division to replace filter screen acceptance division 27.Opposite with filter screen acceptance division 27, filter screen acceptance division 41 does not have overfall 38 now.Or rather, in spill cavity 27b, be furnished with three electrode 42a, 42b and 42c, these electrodes constitute two electrode pair 42a, 42b or 42b, 42c.If water level P (under the situation of limiting water level Pg1) reaches the first electrode pair 42a that ends at equal height, 42b, two electrode 42a, electric current between the 42b changes, and this can be by control device 26 (for example by electric current comparison means 43) sensing directly or indirectly.Level measurement device for example can pass through three electrode 42a, and 42b and 42c and electric current comparison means 43 constitute.
If water level P (under the situation of limiting water level Pg2) also reaches the third electrode 42c that is positioned at higher height, two electrode 42b then, the electric current between the 42c changes, and this also can be by control device 26 sensing directly or indirectly.Thus, can be by means of three electrode 42a, 42b and 42c sensing are as two of limiting water level Pg1 and Pg2 different water level P.Control device 26 for example can trigger different actions then, the warning prompt of the time output of the limiting water level Pg1 below reaching " the flock filter will be expired; please change/clean " form for example, the warning prompt of output " the flock filter is full, please change/clean " form and close drier during limiting water level Pg2 above reaching.
Alternatively, also can only use an electrode pair, perhaps also can use more than electrode pair two, also can differing heights.
Certainly, the embodiment shown in the present invention is not limited to.That is, filter screen acceptance division 27 also can only pour into by the condensate liquid from heat sink 7 drippages.The condensate liquid that is used for cleaning by the first flock filter 12 for example can filter by means of the flock filter of oneself, as shown in WO 2010/028992 A1.Filter screen acceptance division 27 can also only pour into the condensate liquid that flows out from the first flock filter 12.27 of filter screen acceptance divisions for example can be born the function at the second flock filter shown in WO 2010/028992 A1.Shape shown in the shape of filter screen acceptance division and filter screen also is not limited to.Filter screen and filter can use replaceably.
