Abstract

In a dry-cleaning apparatus, a washing drum (2) is mounted rotatably in a surrounding housing (1) and is equipped with a feed line for the solvent and with an outlet line (4) in the lower region of the housing. For the circulation of the drying air after the end of the washing operation and for removing the solvent, lines connected to the housing and a fan (6) are provided. An air cooler (11) serves for condensing the solvent vapours taken up by the drying air and an air heater (14) is used for heating the recycled drying air. So that the heat extracted from the drying air for the condensation of the solvent vapours carried along by the drying air can be reutilized for reheating before blowing into the washing drum, the air cooler is formed by the evaporator (11) and the air heater by the condenser (14) of a heat pump. <IMAGE>

Description

Die Erfindung betrifft eine Trockenreinigungsvorrichtung mit einer Waschtrommel, die in einem umgebenden Gehäuse drehbar gelagert ist, mit einer Zuführungsleitung für das Lösungsmittel und einer Auslaßleitung im unteren Bereich des Gehäuses,mit mit dem Gehäuse verbundenen Leitungen und einem Lüfter zum Umwälzen der Trocknungsluft nach der Beendigung des Waschvorgangs und dem Ableiten des Lösungsmittels und mit einem Luftkühler zum Kondensieren der von der Trocknungsluft mitgeführten Lösungsmitteldämpfe und einem Lufterhitzer zum Erwärmen der zurückgeführten Trocknungsluft.The invention relates to a dry cleaning device with a washing drum, which is rotatably mounted in a surrounding housing, with a feed line for the solvent and an outlet line in the lower region of the housing, with lines connected to the housing and a fan for circulating the drying air after the completion of the Washing and draining the solvent and with an air cooler to condense the solvent vapors carried by the drying air and an air heater to heat the returned drying air.

Bei bekannten Trockenreinigungsvorrichtungen dieser Art wird nach der Beendigung des Waschvorgangs, Ablassen des Lösungsmittels und Schleudern die noch lösungsmittelfeuchte Ware dadurch getrocknet, daß durch den Lüfter durch die Ansaugleitung angesaugte und durch die Einblasleitung der Waschtrommel wieder zugeführte Trocknungsluft im Kreislauf geführt wird. Dabei wird die im Kreislauf geführte Trocknungsluft vor ihrem Eintritt in die Waschtrommel in einem Lufterhitzer, der durch Dampf oder elektrisch beheizt sein kann, erwärmt. Die warme Trocknungsluft verdunstet de noch an der Ware haftende Lösungsmittel und nimmt den Lösungsmitteldampf mit. Die lösungsmitteldampfhaltige Trocknungsluft wird sodanntber einen Luftkühler, der durch eine Kältemaschine gekühlt wird, gekühlt, so daß das verdunstete Lösungsmittel wieder verflüssigt wird und abgeleitet werden kann. Dieser Trocknungsvorgang durch die Führung der Trocknungsluft in dem beschriebenen Kreislauf wird so lange fortgesetzt, bis kein flüssiges Lösungsmittel mehr an der Ware haftet.In known dry cleaning devices of this type, after the completion of the washing process, draining off the solvent and spinning, the still solvent-moist goods are dried in that drying air sucked in by the fan through the suction line and fed back through the blowing line of the washing drum is circulated. The drying air in the circuit is heated in an air heater, which can be heated by steam or electrically, before it enters the washing drum. The warm drying air evaporates the solvent still adhering to the goods and takes the solvent vapor with it. The drying vapor-containing drying air is then cooled via an air cooler, which is cooled by a refrigerator, so that the evaporated solvent is liquefied again and can be removed. This drying process by guiding the drying air in the cycle described continues until no more liquid solvent adheres to the goods.

Nachteilig bei derartigen bekannten Trockenreinigungsvorrichtungen ist, daß die durch die Kältemaschine zur Kondensation der Lösungsmitteldämpfe der Trocknungsluft entzogene Wärme an deren Kondensator wieder anfällt und diesem durch eine Luft-oder Wasserkühlung entzogen werden muß und verlorengeht. Andererseits muß zur erneuten Erwärmung in dem Lufterhitzer der Trocknungsluft Wärme durch Heißdampf oder elektrische Energie zugeführt werden.A disadvantage of such known dry cleaning devices is that the heat extracted by the refrigeration machine to condense the solvent vapors of the drying air occurs again at the condenser and has to be removed by air or water cooling and is lost. On the other hand, heat must be supplied to the drying air by superheated steam or electrical energy for renewed heating in the air heater.

Aufgabe der Erfindung ist es daher, bei einer Trockenreinigungsvorrichtung der eingangs angegebenen Art die zur Kondensation der von der Trocknungsluft mitgeführten Lösungsmitteldämpfe der Trocknungsluft entzogenen Wärme zu deren Wiedererwärmung vor dem Einblasen in die Waschtrommel wieder nutzbar zu machen.The object of the invention is therefore, in a dry cleaning device of the type mentioned, to make the heat extracted from the drying air for condensation of the solvent vapors entrained by the drying air reusable before being blown into the washing drum.

Erfindungsgemäß wird diese Aufgabe bei einer Trockenreinigungs- vorrichtung der eingangs angegebenen Art dadurch gelöst, daß der Luftkühler durch den Verdampfer und der Lufterhitzer durch den Verflüssiger einer Wärmepumpe gebildet sind. Durch die Wärmepumpe wird der umgewälzten Trocknungsluft zur Kondensation der Lösungsmitteldämpfe Wärme entzogen, die in den Trocknungsluftkreislauf vor dem Einblasen der Trocknungsluft in die Waschtrommel wieder zurückgeführt wird. Dadurch wird nicht nur Energie eingespart, sondern auch der Aufbau der Trockenreinigungsvorrichtung vereinfacht, weil zum Abkühlen und anschließendem erneuten Erwärmen der Trocknungsluft lediglich eine Wärmepumpe benötigt wird.According to the invention this object is at a T rockenreinigungs- of the initially indicated type of apparatus achieved in that the air cooler are formed through the evaporator and the air heater through the condenser of a heat pump. The heat pump removes heat from the circulating drying air for the condensation of the solvent vapors, which heat is returned to the drying air circuit before the drying air is blown into the washing drum. This not only saves energy, but also simplifies the structure of the dry cleaning device, because only a heat pump is required to cool and then reheat the drying air.

Zweckmäßigerweise ist nur ein Teilstrom der von dem Lüfter angesaugten Trocknungsluft durch den Trocknungsluftstrom teilende Einrichtungen dem Verdampfer zuführbar, so daß durch entsprechende Steuerung der Teilströme dem über den Verdampfer geleiteten Teilstrom entsprechend der Kapazität der Wärmepumpe die zur Kondensation der Lösungsmitteldämpfe erforderliche Wärmemenge entzogen werden kann.Expediently, only a partial flow of the drying air sucked in by the fan can be fed to the evaporator through the devices dividing the drying air flow, so that by controlling the partial flows appropriately, the amount of heat required for the condensation of the solvent vapors can be withdrawn from the partial flow conducted via the evaporator according to the capacity of the heat pump.

Weiterhin ist es zweckmäßig, daß der durch den Verdichter komprlmierte Kältemitteldampf bzw. das verflüssigte Kältemittel über einen zuschaltbaren Verflüssiger über ein Expansionsventil dem Verdampfer zuführbar ist. Denn um eine Überhitzung der Ware zu vermeiden, kann es erforderlich werden, die Kondensationswärme des Kältemittels nicht vollständig durch den als Lufterhitzer ausgebildeten Verflüssiger an die Trocknungsluft abzugeben, sondern durch den zuschaltbaren Verflüssiger. Die Abgabe von Kondensationswärme durch den zuschaltbaren Verflüssiger kann auch deshalb erforderlich werden, weil durch den Verdichter der Wärmepumpe zusätzlich Wärme an das Kältemittel abgegeben wird.Furthermore, it is expedient that the refrigerant vapor compressed by the compressor or the liquefied refrigerant can be fed to the evaporator via an expandable valve via an expansion valve. Because in order to avoid overheating of the goods, it may be necessary not to release the condensation heat of the refrigerant completely into the drying air through the condenser designed as an air heater, but rather through the switchable condenser. The release of condensation heat by the switchable condenser can also be necessary because the compressor of the heat pump emits additional heat to the refrigerant.

Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt

  • Fig. 2 eine entsprechende Darstellung einer zweiten Ausführungsform. ,
Embodiments of the invention are explained below with reference to the drawing. In this shows
  • Fig. 1 shows a first embodiment of the dry cleaning device in a schematic representation.
  • Fig. 2 shows a corresponding representation of a second embodiment. ,

In einem trommelförmigen Gehäuse 1 ist die Waschtrommel 2 drehbar gelagert. In dieser Waschtrommel 2 wird die durch nicht dargestellte Klappen einführbare Ware 3 auch getrocknet.The washing drum 2 is rotatably mounted in a drum-shaped housing 1. In this washing drum 2, the goods 3 that can be inserted through flaps (not shown) are also dried.

Das in das Gehäuse 1 eingeführte Lösungsmittel wird nach dem Reinigungsvorgang durch die Leitung 4 abgezogen, während die überlaufleitung 5 sicherstellt, daß der Lösungsmittelspiegel das vorherbestimmte Niveau nicht überschreitet.The solvent introduced into the housing 1 is drawn off through the line 4 after the cleaning process, while the overflow line 5 ensures that the solvent level does not exceed the predetermined level.

Nach dem Ableiten des Lösungsmittels und dem Schleudern der Waren 3 wird diese in einem Trocknungsluftstrom getrocknet. Dabei wird von dem Lüfter 6 durch die Ansaugleitung 7 Luft aus dem Gehäuse 1 angesaugt. Die angesaugte Trocknungsluft tritt über den Flusenfilter 8 in den Lüfter 6 ein und wird hinter diesem durch die einstellbare Klappe 9 in zwei Teilströme 10, 10' aufgeteilt. Der Teilstrom 10' wird über den Luftkühler 11 geleitet, der durch den Verdampfer einer Wärmepumpe gebildet ist. In dem Luftkühler 11 wird der Teilstrom 10' der Trocknungsluft so weit abgekühlt, daß sich in dem trichterförmigen Boden der Kühlkammer 12 das auskondensierte Lösungsmittel sammelt und durch die nur strichpunktierte Leitung 13 abgezogen wird. Hinter dem Luftkühler 11 vereinigen sich die Teilströme 10, 10' wieder und treten gemeinsam durch den Lufterhitzer 14, der durch den Verflüssiger der Wärmepumpe gebildet ist. Durch die Einblasleitung 15 tritt die erwärmte Trocknungsluft wieder in das Gehäuse 1 ein und entzieht durch Verdampfen der Ware das an dieser haftende Lösungsmittel. Das Gehäuse 1, die Ansaugleitung 7, der Kühlraum 12, die Umgehungsleitung für den Teilstrom 10, die Überhitzungskammer 14 und die Einblasleitung 15 bilden ein geschlossenes System.After removing the solvent and spinning the goods 3, this is dried in a drying air stream. Air is drawn in from housing 1 by fan 6 through suction line 7. The suctioned drying air enters the fan 6 via the lint filter 8 and is split behind it by the adjustable flap 9 into two partial streams 10, 10 '. The partial flow 10 'is passed through the air cooler 11, which is formed by the evaporator of a heat pump. In the air cooler 11, the partial flow 10 ′ of the drying air is cooled to such an extent that the condensed-out solvent collects in the funnel-shaped bottom of the cooling chamber 12 and is drawn off through the only dash-dotted line 13. Behind the air cooler 11, the partial flows 10, 10 'reunite and pass together through the air heater 14, which is by the Condenser of the heat pump is formed. The heated drying air re-enters the housing 1 through the blowing line 15 and removes the solvent adhering to it by evaporation of the goods. The housing 1, the suction line 7, the cooling chamber 12, the bypass line for the partial flow 10, the overheating chamber 14 and the injection line 15 form a closed system.

Die Wärmepumpe besteht aus dem Verdichter 16, der den angesaugten Kältemitteldampf verdichtet, so daß sich das Kältemittel durch Erhöhung seines Siedepunktes in dem Verflüssiger 14 wieder verflüssigt und seine dabei entstehende Kondensationswärme an die Trocknungsluft abgibt. Das verflüssigte Kältemftel wird sodann durch eine nicht dargestellte Leitung in den Vorratsbehälter 17 für das Kältemittel geleitet. Aus dem Vorratsbehälter gelangt das Kältemittel über ein Filter 18, ein Schauglas 19 und ein Magnetventil 20 zu dem Expensionsventil 21, durch das das Kältemittel gedrosselt und nach Entspannung in den Verdampfer 11 eingespritzt wird. In dem durch den Verdampfer 11 gebildeten Luftkühler entzieht das Kältemittel seine Verdampfungswärme dem Teilstrom 10' der Trocknungsluft.The heat pump consists of the compressor 16, which compresses the sucked-in refrigerant vapor, so that the refrigerant liquefies again by increasing its boiling point in the condenser 14 and releases its heat of condensation to the drying air. The liquefied refrigerant is then passed through a line (not shown) into the storage container 17 for the refrigerant. From the reservoir, the refrigerant passes through a filter 18, a sight glass 19 and a solenoid valve 20 to the expansion valve 21, through which the refrigerant is throttled and injected into the evaporator 11 after expansion. In the air cooler formed by the evaporator 11, the refrigerant extracts its heat of vaporization from the partial flow 10 ′ of the drying air.

Durch den Druckschalter P1 kann der Zusatzkondensator 23 zugeschaltet werden, über den sodann das verflüssigte Kältemittel in den Vorratsbehälter 17 zurückfließt. Der Zusatzkondensator 23 wird zugeschaltet, wenn der Druck in dem Kältemittel auf der Druckseite zu weit ansteigt. Dies ist erforderlich, weil dem Kältemittel nicht nur die in dem Luftkühler aufgenommene Verdampfungswärme, sondern auch aus der mechanischen Arbeit des Verdichters 16 umgewandelte Wärme zugeführt wird.The additional condenser 23 can be switched on by the pressure switch P 1 , via which the liquefied refrigerant then flows back into the storage container 17. The additional condenser 23 is switched on when the pressure in the refrigerant rises too far on the pressure side. This is necessary because not only the heat of vaporization absorbed in the air cooler, but also heat converted from the mechanical work of the compressor 16 is supplied to the refrigerant.

Der Zusatzkondensator 23 wird auch dann zugeschaltet, wenn die an dem Trocknungsthermostat 24 eingestellte Temperatur derTrocknungsluft erreicht ist. In diesem Zeitpunkt öffnet das Umgehungsventil 25 und die Wärme wird nur noch durch den Zusatzkondensator 3 abgeführt. Eine Uberhitzung der Ware 3 wird dadurch vermieden.The additional capacitor 23 is also switched on when the temperature set on the drying thermostat 24 the drying air is reached. At this time, the bypass valve 25 opens and the heat is only dissipated through the additional condenser 3. Overheating of the goods 3 is thereby avoided.

Zur Überwachung des Gesamtsystems ist ein Sicherheitsdurckschalter 26 vorgesehen, der die Wärmepumpe und die Trockeneinrichtung im Störungsfall abschaltet.To monitor the entire system, a safety push-button switch 26 is provided, which switches off the heat pump and the drying device in the event of a fault.

Der Arbeitsdruckschalter 27 schaltet den Verdichter 16 in Abhängigkeit des Saugdruckes ein und aus. An diesem Arbeitsdruckschalter 27 werden auch die zur Verflüssigung des Lösungsmittels am Luftkühler 11 erforderlichen Temperaturen eingestellt.The working pressure switch 27 switches the compressor 16 on and off depending on the suction pressure. The temperatures required to liquefy the solvent on the air cooler 11 are also set on this working pressure switch 27.

Die in Fig. 2 schematisch dargestellte Vorrichtung unterscheidet sich von der Vorrichtung nach Fig. 1 dadurch, daß die Trocknungsluft aus dem Gehäuse 1 durch eine an dessen unteren Bereich angeschlossene Ansaugleitung 28 abgezogen wird. Weiterhin ist die Verbindungsleitung 29 von dem Luftkühler 11 zu dem Lufterhitzer 14 ansteigend ausgebildet. Durch diese Ausgestaltung ist sichergestellt, daß im Falle der Abschaltung der Anlage aus den die Trocknungsluft führenden Leitungen keine lösungsmittelhaltige Luft in die Waschtrommel zurückgelangen kann. Bei der Ausführungsform nach Fig. 2 kann daher auf die Luftleitungen verschließende Klappen 30, 31 verzichtet werden.The device shown schematically in FIG. 2 differs from the device according to FIG. 1 in that the drying air is drawn out of the housing 1 through a suction line 28 connected to its lower region. Furthermore, the connecting line 29 is designed to rise from the air cooler 11 to the air heater 14. This configuration ensures that, in the event of the system being switched off, no air containing solvent can get back into the washing drum from the lines carrying the drying air. In the embodiment according to FIG. 2, flaps 30, 31 closing the air lines can therefore be dispensed with.
