A washing machine equipped for drying has a condenser consisting of a hollow body (1), through which damp process air flows through. For cooling purposes, the hollow body (1) is rinsed with water via a connectable valve in the water supply unit (4). A bell (11) with a cylindrical inner wall and a tangentially ending supply nipple (12) is located in the supply (4) directly before the discharge opening into the hollow body (1).

Description

Die Erfindung betrifft eine zum Trocknen eingerichtete Waschmaschine mit einem Kondensator, der aus einem im wesentlichen von unten nach oben mit feuchter Prozeßluft durchströmbaren Hohlkörper besteht und zu Kühlzwecken über ein schaltbares Ventil im Zulauf mit Leitungswasser bespült wird.The invention relates to a set up for drying Washing machine with a condenser that essentially consists of one from the bottom up with moist process air flowable hollow body and for cooling purposes a switchable valve in the inlet is rinsed with tap water becomes.

Ein solcher sogenannter Waschtrockner ist aus der deutschen Offenlegungsschrift 41 04 760 bekannt. In einem darin angeordneten Kondensator hat sich als Problem erwiesen, daß sowohl während des Trocknungsabschnittes in der Prozeßluft wie auch während des Waschgangs in der Lauge mitgetragene Wäscheflusen sich an der Innenwandung des Kondensators absetzen und nach Ende des Trocknungsabschnitts antrocknen können. Diese Gefahr wird insb. dadurch begünstigt, daß man aus Gründen der Ersparnis von frischem Kühlwasser den Durchfluß des Kühlwassers auf einen möglichst kleinen Wert begrenzt. Durch geeignete, konstruktive Maßnahmen innerhalb des Kondensator-Hohlkörpers wird zwar eine möglichst breitflächige Verteilung des Kühlwassers angestrebt, jedoch werden dadurch nicht alle Wandbereiche gleichmäßig benetzt, an denen sich dann noch Flusen absetzen, und außerdem strömen noch erhebliche Flusenanteile mit der Prozeßluft durch den Kondensator bis ins Gebläse, in dem sich die Flusen dann schließlich absetzen.Such a so-called washer dryer is from the German Laid-open publication 41 04 760. In one arranged in it Capacitor has proven to be a problem that both during the drying section in the process air like laundry fluff also carried in the lye during the wash cycle settle on the inside wall of the condenser and can dry after the end of the drying section. This danger is particularly favored by the fact that To save fresh cooling water the flow the cooling water to a value that is as small as possible. Through suitable, constructive measures within the hollow capacitor body will be as wide as possible Distribution of the cooling water is aimed for, however not all areas of the wall wetted evenly then settle fluff, and there are also considerable streams Lint shares with the process air through the condenser to the blower, in which the lint then settles.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Waschmaschine so zu verbessern, daß die im Kondensator sowohl beim Waschen wie auch beim Trocknen sich absetzenden Flusen wieder ausgespült werden können. Dabei soll die für den Kondensationsprozeß und auch zum Flusenspülen benötigte Wassermenge so klein wie möglich gehalten werden. Beide Funktionen sollen über denselben Wasserweg realisiert werden.The invention has for its object the above Improve washing machine so that in the condenser settling both when washing and drying Fluff can be rinsed out again. In doing so those for the condensation process and also for rinsing the fluff required amount of water can be kept as small as possible. Both functions should be implemented via the same waterway will.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß im Zulauf unmittelbar vor der Auslauföffnung in den Hohlkörper eine Glocke mit wenigstens annähernd zylindrischer Innenwandung und mit tangential mündendem Zulaufstutzen geschaltet ist. Dadurch wird das Zufluß-Wasser in der Glocke schraubenförmig geführt und tritt breit gefächert aus der Auslauföffnung aus. Es erreicht so alle Wandbereiche des Hohlkörpers und spült sie frei von Flusen. Die dazu nötige Wassermenge kann dennoch klein gehalten werden.According to the invention this object is achieved in that Inlet immediately before the outlet opening in the hollow body a bell with at least approximately cylindrical inner wall and switched with a tangentially opening inlet connection is. This will make the inflow water helical in the bell out and comes out of the outlet opening out. It reaches all wall areas of the hollow body and rinses them free of lint. The amount of water required for this can still be kept small.

In besonders vorteilhafter Weise wird die Erfindung dadurch weitergebildet, daß unmittelbar unter der Auslauföffnung eine Prallplatte angeordnet ist, die das Spül- bzw. Kühlwasser glockenförmig nach allen Seiten verteilt. Hierdurch kann eine noch gleichmäßigere Bespülung der Flächenabschnitte der Innenwände des Kondensator-Hohlkörpers erreicht werden, an denen sich evtl. Flusen abgesetzt haben könnten. Außerdem bewirkt die glockenförmige Verteilung einen weitgehend intensiven Kontakt des Kühlwassers mit dem Prozeßluftstrom, so daß die von der Prozeßluft mitgerissenen Flusen nicht zum Gebläse gelangen.The invention is thereby particularly advantageous trained that immediately under the outlet opening a baffle plate is arranged, the rinsing or cooling water distributed in a bell shape on all sides. This can an even smoother flushing of the surface sections of the Inner walls of the hollow capacitor body can be reached which may have fluff. Furthermore the bell-shaped distribution creates a largely intense Contact of the cooling water with the process air flow, see above that the lint entrained by the process air does not Fan.

Der Kondensator-Hohlkörper 1 ist entsprechend den in der Waschmaschine verbliebenen Freiräumen geformt und wird von der unten angeordneten Zuluftöffnung 2 bis zur oben angeordneten Gebläse-Anschlußöffnung 3 im wesentlichen von unten nach oben mit feuchter Prozeßluft durchströmt. Dies ist durch die hohl gezeichneten großen Pfeile angedeutet. Die unten angeordnete Zuluftöffnung 2 ist in nicht dargestellter Weise an einen Laugenbehälter der Waschmaschine angeschlossen und dient gleichfalls als Abflußöffnung für von oben zugeführtes und im Hohlkörper als solches verbrauchtes Spül-bzw. Kühlwasser. Aus dem Laugenbehälter wird es in üblicher Weise durch eine Laugenpumpe abgepumpt. The capacitor hollow body 1 is corresponding to that in the The remaining free space is shaped by the washing machine the supply air opening 2 at the bottom to the one at the top Fan connection opening 3 essentially from below flowed upwards with moist process air. This is indicated by the large, hollow arrows. The the supply air opening 2 arranged at the bottom is shown in FIG Way connected to a washing machine tub and also serves as a drain opening for feed from above and in the hollow body as such rinsing or. Cooling water. From the tub it becomes more common Pumped out by a drain pump.

Der Zulauf 4 enthält ein nicht dargestelltes Magnetventil und mündet über eine Glocke 11 auf eine Prallplatte 5, die das zulaufende Wasser glockenförmig im Hohlraum des Kondensators verteilt. Es wird in Form eines Sprühnebels gleichmäßig verteilt und fließt zum Teil an den Innenwänden des Hohlkörpers 1 zur Zuluft- und Abflußöffnung 2 herab.The inlet 4 contains a solenoid valve, not shown and opens via a bell 11 on a baffle plate 5, the the incoming water bell-shaped in the cavity of the condenser distributed. It becomes even in the form of a spray distributed and partly flows on the inner walls of the Hollow body 1 down to the supply air and drain opening 2.

Zum normalen Kondensieren der Prozeßluft-Feuchtigkeit wird das Kühlwasser über den Zulauf 4 beispielsweise intermittierend zugeführt. Damit in den Zuführungspausen der Innenraum des Kondensators nicht austrocknet, wodurch weder eine Kondensation noch ein Flusenauswaschen stattfinden würde, kann im oberen Teil im Zulaufbereich der Wasserzuführung 4 ein Stauraum 8 angeordnet sein, dessen Stauwand 9 Abflußöffnungen 10 aufweist. Die Abflußöffnungen sind in ihrer Größe so bemessen, daß sie den verzögerten Ablauf des aufgestauten Kühlwassers in einer Zeit gestatten, die etwa der Wasserzuführungs-Pause entspricht. Dabei können die Abflußöffnungen 10 wie im dargestellten Beispiel an den Seiten der Stauwand 9 oder nur an der unteren Seite oder in Form von Löchern angeordnet ein. Der Stauraum 8 kann auch, anders als hier dargestellt, ringförmig oder U-förmig um den Querschnitt des Hohlkörpers herum angeordnet sein und seine Abflußöffnungen von drei oder vier Seiten aus in den Prozeßluft-Strom richten. Maßgebend für die Gestaltung des Hohlkörpers und des Stauraumes sind im wesentlichen die örtlichen Gegebenheiten in einer Waschmaschine, in der dieser Kondensator angeordnet sein soll.For normal condensation of the process air humidity the cooling water via the inlet 4, for example, intermittently fed. So the interior during the feeding breaks the condenser does not dry out, causing neither condensation a fluff wash out could take place in the upper part in the inlet area of the water supply 4 Storage space 8 may be arranged, the storage wall 9 drain openings 10 has. The drainage openings are so big in size dimensioned that they delay the expiry of the pent up Allow cooling water at a time such as the water supply break corresponds. The drainage openings can 10 as in the example shown on the sides of the dam wall 9 or arranged only on the lower side or in the form of holes a. The storage space 8 can also, unlike shown here, annular or U-shaped around the cross section of the Be placed around the hollow body and its drainage openings direct from three or four sides into the process air flow. Decisive for the design of the hollow body and the Storage space are essentially the local conditions in a washing machine in which this capacitor is placed should be.

Der Frischwasserzulauf mit seinem hier nicht dargestellten Ventil kann beispielsweise auf eine große Wasserdurchlaufmenge zum Ausspülen der Flusen ausgelegt sein. Da zum Kondensieren nur eine kleinere Wasserdurchlaufmenge benötigt wird, kann das Ventil für den Kondensationsprozeß taktweise eingeschaltet werden. Die Prallplatte 5 unter der Glocke 11 zwingt einen Teil des Frischwassers an den Wänden herabzulaufen. Es spült die Wände auch während des Kondensationsprozesses von Flusen frei. Durch die intensive Verwirbelung und Vernebelung eines Teils des Kühlwassers werden Flusen besonders wirksam aus der Prozeßluft ausgewaschen und der Kondensationseffekt verbessert. In den Taktpausen der Wasserzufuhr übernimmt der Wasservorrat im Stauraum 8 die Bespülung der Innenwände des Hohlkörpers 1.The fresh water inlet with its not shown here For example, the valve may have a large water flow rate be designed to rinse out the fluff. Because to condense only a smaller water flow is required the valve for the condensation process can be cycled be switched on. The baffle plate 5 under the bell 11 forces some of the fresh water to run down the walls. It also rinses the walls during the condensation process free of fluff. Due to the intensive swirling and atomizing part of the cooling water becomes fluff washed out particularly effectively from the process air and the Condensation effect improved. In the intervals between water supply The water supply in storage space 8 takes over the rinsing the inner walls of the hollow body 1.

Der Hohlkörper des Kondensators ist im allgemeinen so ausgebildet, daß das Wasser von der höchsten Stelle über eine Prallplatte wenigstens teilweise an allen Wänden herunter läuft. Zweckmäßigerweise wird das während des Flusenspülvorganges anfallende und durch die Zuluftöffnung 2 in den Laugenbehälter der Waschmaschine abfließende Wasser sofort mittels der Laugenpumpe abgepumpt, damit keine Flusen an die Wäsche gelangen können. Diese Flusen werden dann gleichzeitig mit dem abzupumpenden Wasser entfernt.The hollow body of the capacitor is generally designed that the water from the highest point over a Baffle plate down at least partially on all walls running. This is expedient during the lint rinsing process accruing and through the supply air opening 2 in the tub water flowing out of the washing machine immediately pumped out of the drain pump, so that no fluff on the Laundry. These fluff will then be at the same time removed with the water to be pumped out.

Da auch beim Waschen Flusen aus der Wäsche gelöst werden, die vom Waschmittelschaum in den Kondensator getragen werden, ist es zweckmäßig, während des Waschabschnitts, z.B. während der Spülgänge, in Abständen Kondensatorspülungen vorzunehmen. Vorteilhafterweise sind diese Kondensatorspülungen dann vorzunehmen, wenn im Laugenbehälter ein niedriger Wasserstand vorhanden ist, der nicht an die Zuluftöffnung 2 des Kondensators heranreicht, also z.B. am Ende jedes Spülgangs. Vorteilhafterweise kann man während der Zuführung von Frischwasser das Gebläse und die Pumpe laufen lassen. Since fluff is removed from the laundry even when washing, carried by the detergent foam into the condenser, it is convenient to use e.g. condenser rinsing at intervals during the rinsing cycles to make. These condenser rinses are advantageous to be carried out if there is a low level in the tub Water level is present that is not at the supply air opening 2 of the capacitor, e.g. at the end of each Rinse cycle. One can advantageously during the feeding Let the blower and pump run with fresh water.

Dadurch wird der obere Teil des Kondensator-Hohlkörpers durch direktes Bespülen der Wände und der senkrechte Teil des Hohlkörpers durch Verwirbelung des Wassers von Flusen befreit. Bei regelmäßiger automatischer Anwendung während des Waschprozesses genügt zum Flusenspülen eine jeweils geringe Wassermenge.This will make the upper part of the hollow capacitor body by directly washing the walls and the vertical part of the hollow body by swirling the water from fluff exempted. With regular automatic use during the washing process is sufficient to rinse the fluff Amount of water.

Die beschriebenen Maßnahmen erfordern nur ein Zulaufventil und einen Schlauch zum Kondensator-Zulauf 4. Auch sind keine weiteren Bauelemente für etwa ein zweites Ventil nötig, da die Steuerung der Wasserdurchflußmengen durch unterschiedlich langes bzw. taktweises Einschalten des Ventils bewerkstelligt werden kann.The measures described only require an inlet valve and a hose to the condenser inlet 4. There are also none Additional components for a second valve are necessary because the control of water flow rates by different long or intermittent switching on of the valve accomplished can be.

Erfindungsgemäß wird der Effekt einerseits des Kondensierens des Wasserdampfes aus der Prozeßluft und andererseits des Flusenspülens durch die besondere Ausgestaltung des Wasserzulaufs 4 in den Kondensator-Hohlkörper 1 erhöht. Fig. 3 und 4 gehen hierauf genauer ein. Die Glocke 11 hat einen tangentialen Zulaufstutzen 12 und ist in einen oberen waagerechten Wandungsteil 13 des Hohlkörpers 1 nach unten überstehend eingesetzt. Sie kann je nach innerer Formung der umgebenden Wandbereiche noch weiter überstehen oder flächenbündig eingesetzt sein. Die Glocke 11 hat eine zylindrische Innenwandung 14. Die Innenwandung kann sich aber auch, falls sich dadurch irgendwelche Vorteile ergeben, z.B. Aufhebung der Wasserreibung an der Innenwandung durch Zentrifugal-Beschleunigung, nach unten leicht konisch erweitern. Unten endet die Glocke 11 in der Auslauföffnung 15, die im Abstand B von der - entlang einer geraden Linie geschnitten dargestellten - Prallplatte 5 verdeckt ist. Die Prallplatte 5 ist dabei durch eine zentral im Innenraum der Glocke 11 angebrachte Säule 16 gehalten und so groß im Durchmesser wie die Glocke 11 in Höhe ihrer Öffnung 15. According to the invention, the effect of condensing on the one hand the water vapor from the process air and on the other hand the Flush rinsing through the special design of the water inlet 4 increased in the capacitor hollow body 1. Fig. 3 and 4 go into this in more detail. The bell 11 has a tangential Inlet pipe 12 and is in an upper horizontal Wall part 13 of the hollow body 1 protruding downwards used. Depending on the inner shape of the surrounding Wall areas protrude even further or used flush be. The bell 11 has a cylindrical inner wall 14. The inner wall can also, if there is this gives any advantages, e.g. Repeal of Water friction on the inner wall by centrifugal acceleration, expand slightly conically downwards. Bottom ends the bell 11 in the outlet opening 15, the distance B of which - shown cut along a straight line - Baffle plate 5 is covered. The flapper 5 is thereby by a centrally located in the interior of the bell 11 Column 16 held and as large in diameter as that Bell 11 at the level of its opening 15.

Diese Anordnung bewirkt, daß das näher am Boden 17 als an der Öffnung 15 zufließende Wasser schraubengangförmig verwirbelt wird und mit diesem Drall aus dem Ringspalt 18 zwischen dem unteren Rand der Glocke 11 und der Prallplatte 5 breit gefächert austritt. Es zerstäubt dabei in unzählige Strahlen 19 von Nebeltröpfchen, die den Innenraum des Hohlkörpers erfüllen und gegen die Strömung der Prozeßluft verhältnismäßig langsam absinken. Inre dadurch maximale Oberfläche ist am effektivsten hinsichtlich der Kondensations-Wirkung gegenüber der Feuchtigkeit in der Prozeßluft. Außerdem ist diese Form der Wasserverteilung für den Flusenspül-Vorgang am besten geeignet, weil das Wasser auf diese Weise überall dorthin verteilt wird, wo sich Flusen überhaupt absetzen können.This arrangement causes the closer to the bottom 17 than at the water flowing into the opening 15 swirled like a screw is and with this twist from the annular gap 18 between the lower edge of the bell 11 and the baffle plate 5 exits broadly. It atomizes in countless ways Rays 19 of droplets of fog covering the interior of the hollow body meet and proportionate to the flow of process air slowly sink. Thereby maximum surface area is most effective in terms of condensation against the moisture in the process air. Furthermore is this form of water distribution for the lint rinsing process best suited because of the water this way is distributed everywhere where lint settles can.

Nur an einer Stelle der Austrittsfläche des Ringspaltes 18 entsteht ein Schattenbereich S (Fig. 4), der auch von den Grenzstrahlen 20 der Nebeltröpfchen nicht mehr erreicht wird. Die Lage dieses Schattenbereiches hängt im wesentlichen von der Lage des Zulaufstutzens 12, der Breite B des Ringspaltes 18, dem Durchmesser der Innenwandung 14 und der Größe der Mündungsfläche des tangentialen Zulaufstutzens 12 ab. Beispielsweise hat sich als wesentliche Bemessungsregel erwiesen, daß die vom Durchmesser der Prallplatte 5 und der Breite B des Ringspalts 18 bestimmte Austrittsfläche des Ringspalts zwei bis drei Mal so groß sein sollte wie die Mündungsfläche des Zulaufstutzens 12. Dadurch ist u.a. auch der Weg des schraubengangförmigen Wasserstrahls 21 innerhalb der Glocke 11 bestimmt und sein jeweiliger Austrittsbereich. Der Schattenbereich S wird vorzugsweise auf die Gebläseanschluß-Öffnung 3 (Fig. 1) hin gerichtet. Auf diese Weise vermeidet man eine direkte Einsprühung ins Gebläse, und die Gefahr des Mitreißens von Wassertropfen ist so gut wie gebannt.Only at one point on the exit surface of the annular gap 18 creates a shadow area S (Fig. 4), which also by the Limit rays 20 of the fog droplets no longer reached becomes. The location of this shadow area essentially depends from the position of the inlet connector 12, the width B of the Annular gap 18, the diameter of the inner wall 14 and the Size of the mouth area of the tangential inlet connection 12 from. For example, it has become an essential design rule proved that the diameter of the baffle plate 5 and Width B of the annular gap 18 certain exit surface of the Annular gap should be two to three times as large as that Mouth surface of the inlet connector 12.This means, among other things, also the path of the helical water jet 21 within the bell 11 determines and its respective exit area. The shadow area S is preferably on the blower port opening 3 (Fig. 1) directed. In this way you avoid direct spraying into the blower, and that The risk of water droplets being carried along is virtually eliminated.

Damit sich die vorstehend genannten Absichten optimal erfüllen, ist aber auch auf eine Bemessung des Volumens der Glokke 11 zu achten, bei der sich das Zulaufwasser aufgrund seiner Abbremsung an der Innenwandung 14 und an den Unstetigkeiten des Ringspaltes 18 im Innenraum der Glocke 11 gerade nicht mehr staut.So that the above-mentioned intentions are optimally fulfilled, is also based on a measurement of the volume of the bell 11 to be observed, in which the inlet water due to its Braking on the inner wall 14 and on the discontinuities of the annular gap 18 in the interior of the bell 11 straight no longer jams.
