Abstract

The invention relates to a drying appliance, especially a condensation-type laundry dryer, with a heat pump through which a refrigerant flows, with an evaporator, with a condenser, with a refrigerant conduit and with an air circuit, in which the airstream for heating is guided via the condenser of the heat pump and subsequently into an air inlet of a drying chamber containing the material to be dried, and in which the airstream for cooling is guided out of an air outlet of the drying chamber at least partially via a heat exchanger containing the evaporator of the heat pump, and with a second heating device preferably arranged upstream of the air inlet of the drying chamber. In order to guarantee reliable operation at all times in such a drying appliance, there is installed a monitoring and regulating device which regulates the heating capacity of the second heating device in dependence on the refrigerant pressure in the heat pump or on a parameter dependent on the refrigerant pressure.

Description

Die Erfindung betrifft ein Trockengerät, insbesondere einen Kondensationswäsche­ trockner, mit einer von einem Kältemittel durchströmten Wärmepumpe, mit einem Verdampfer, einem Verflüssiger und einer Kältemittelleitung, mit einem Luftkreis­ lauf, bei welchem der Luftstrom zur Erwärmung über den Verflüssiger der Wärme­ pumpe und anschließend in einen Lufteinlaß eine das Trockengut enthaltende Trockenkammer geleitet wird, und bei dem der Luftstrom zur Abkühlung aus ei­ nem Luftauslaß der Trockenkammer zumindestens teilweise über einen den Ver­ dampfer der Wärmepumpe enthaltenden Wärmetauscher geleitet wird, und mit ei­ ner zweiten, vorzugsweise vor dem Lufteinlaß der Trockenkammer angeordneten Heizvorrichtung.The invention relates to a drying device, in particular a condensation wash dryer, with a heat pump through which a refrigerant flows, with a Evaporator, a condenser and a refrigerant line, with an air circuit run, in which the air flow for heating via the heat condenser pump and then into an air inlet containing the dry material Drying chamber is passed, and in which the air flow for cooling from egg nem air outlet of the drying chamber at least partially via a Ver steamer of the heat pump containing heat exchanger is passed, and with egg ner second, preferably arranged in front of the air inlet of the drying chamber Heater.

Ein solches Trockengerät ist aus der DE-OS 31 13 471 bekannt. Hierbei soll durch die Zusatzheizung eine Verkürzung der Trockenzeit bewirkt werden. Aus der vor­ genannten Schrift ist weiterhin bekannt, die Heizleistung der Zusatzheizung in Ab­ hängigkeit von der Temperatur und der Feuchte der Trocknungsluft zu regeln. Bei dem vorgenannten Gerät besteht der Nachteil, daß am Verflüssiger des Wärme­ tauschers unerlaubt hohe Temperaturen entstehen können. Durch eine zusätzliche Heizung kann eine solche Temperaturerhöhung zur Zerstörung des gesamten Wärmepumpensystems führen.Such a drying device is known from DE-OS 31 13 471. Here is supposed to the additional heating can shorten the drying time. From the front mentioned font is also known, the heat output of the auxiliary heater in Ab depending on the temperature and humidity of the drying air. At the above device has the disadvantage that the heat condenser exchangers may generate unauthorized high temperatures. With an additional Such heating can destroy the entire temperature Heat pump system.

Der Erfindung liegt somit das Problem zugrunde, bei einem Trockengerät gemäß Oberbegriff des Patentanspruchs 1 zu jeder Zeit einen sicheren Betrieb zu ge­ währleisten.The invention is therefore based on the problem in accordance with a drying device The preamble of claim 1 ensures safe operation at all times guarantee.

Erfindungsgemäß wird dieses Problem durch einen Gegenstand mit den Merkma­ len des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by an object with the characteristics len of claim 1 solved. Advantageous configurations result from the following subclaims.

Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung rein schematisch dar­ gestellt und wird anhand der nachfolgenden Beschreibung näher erläutert. An embodiment of the invention is shown purely schematically in a drawing and is explained in more detail with the aid of the following description.  

Die Figur zeigt schematisch in einem Blockdiagramm das Funktionsprinzip eines erfindungsgemäß aufgebauten Kondensationswäschetrockners. Dieser besitzt eine drehbar gelagerte Trommel (1) zur Aufnahme von Wäsche. In die Trommel (1) wird im hinteren Bereich ein erwärmter Luftstrom über einen Lufteinlaß (2) eingeleitet und über die zu trocknende Wäsche geführt. Dieser Luftstrom nimmt die Feuchtigkeit aus der Wäsche auf und wird im vorderen Bereich der Trommel (1) durch einen Luftauslaß (3) abgeleitet.The figure shows schematically in a block diagram the functional principle of a condensation clothes dryer constructed according to the invention. This has a rotatably mounted drum ( 1 ) for holding laundry. A heated air flow is introduced into the drum ( 1 ) in the rear region via an air inlet ( 2 ) and passed over the laundry to be dried. This air flow absorbs the moisture from the laundry and is discharged through an air outlet ( 3 ) in the front area of the drum ( 1 ).

Unterhalb der Trommel (1) ist eine Wärmepumpeneinheit angeordnet, die aus einem Verdampfer (4), einem Verflüssiger (5), einem Kompressor (6) und einem Drosselorgan (7) besteht. Diese sind in einem geschlossenen Kreislauf durch ein Rohrleitungssystem verbunden und werden von einem Kältemittel (8) durchströmt.A heat pump unit, which consists of an evaporator ( 4 ), a condenser ( 5 ), a compressor ( 6 ) and a throttle element ( 7 ), is arranged below the drum ( 1 ). These are connected in a closed circuit by a pipeline system and a refrigerant ( 8 ) flows through them.

Der Verdampfer (4) entzieht der feuchtigkeitsbeladenen Luft Wärme. Damit im Verdampfer (4) fortwährend Kältemittel (8) verdampfen kann, saugt der Kompressor (6) den Kältemitteldampf ab und verdichtet ihn. Dabei bringt er ihn auf einen hohen Druck, wodurch sich die Temperatur des verdampften Kältemittels (8) erhöht.The evaporator ( 4 ) extracts heat from the moisture-laden air. So that refrigerant ( 8 ) can evaporate continuously in the evaporator ( 4 ), the compressor ( 6 ) draws off the refrigerant vapor and compresses it. He brings it to a high pressure, which increases the temperature of the evaporated refrigerant ( 8 ).

Das nun unter hohem Druck und erhöhter Temperatur stehende, dampfförmige Kältemittel (8) strömt in den Verflüssiger (5), über dessen Oberfläche die Wärme an die abgekühlte Prozeßluft abgegeben wird. Dabei verflüssigt sich das Kältemittel (8). Der Druck bleibt konstant.The vaporous refrigerant ( 8 ), which is now under high pressure and elevated temperature, flows into the condenser ( 5 ), over the surface of which the heat is released to the cooled process air. The refrigerant ( 8 ) liquefies. The pressure remains constant.

Das wieder verflüssigte Kältemittel (8) gelangt nun durch das Drosselorgan (7) in den Verdampfer (4). Beim Durchströmen des Drosselorgans (7) wird das Kältemittel (8) auf den im Verdampfer (4) herrschenden Druck entspannt. Der Kreislauf beginnt von neuem.The re-liquefied refrigerant ( 8 ) now passes through the throttle element ( 7 ) into the evaporator ( 4 ). When flowing through the throttle body ( 7 ), the refrigerant ( 8 ) is expanded to the pressure prevailing in the evaporator ( 4 ). The cycle begins again.

Dabei fungiert der Verdampfer (4) der Wärmepumpe als Wärmetauscher, in welchem die Prozeßluft abgekühlt und auf diese Weise durch Kondensation entfeuchtet wird. Die Flüssigkeit wird in einem Kondenswasserbehälter (10) aufgefangen.The evaporator ( 4 ) of the heat pump acts as a heat exchanger in which the process air is cooled and in this way is dehumidified by condensation. The liquid is collected in a condensed water container ( 10 ).

Anschließend wird die abgekühlte Luft am Verflüssiger (5) der Wärmepumpe erneut erhitzt. Ein dem Verflüssiger (5) nachgeordnetes Prozeßluftgebläse (9) sorgt für eine Zirkulation der Trocknungsluft. The cooled air is then heated again at the condenser ( 5 ) of the heat pump. A process air blower ( 9 ) arranged downstream of the condenser ( 5 ) ensures circulation of the drying air.

Um eine schnellere Aufheizung des Prozeßluftstroms zu erreichen, ist zwischen dem Prozeßluftgebläse (9) und dem Lufteinlaß (2) eine zweite Heizvorrichtung in Form einer elektrischen Widerstandsheizung (11) angeordnet. Diese Widerstandsheizung (11) kann über einen von der elektronischen Programmsteuerung (12) betätigten Schalter (13) ein- und ausgeschaltet werden.In order to achieve a faster heating of the process air flow, a second heating device in the form of an electrical resistance heater ( 11 ) is arranged between the process air blower ( 9 ) and the air inlet ( 2 ). This resistance heater ( 11 ) can be switched on and off via a switch ( 13 ) actuated by the electronic program control ( 12 ).

Eine Ausschaltung der Widerstandsheizung (11) erfolgt, wenn der Druck des Kältemittels (8) während der Trocknungsphase einen kritischen Wert übersteigt. Hierzu ist am Verbindungsrohr (14) zwischen Kompressor (6) und Verflüssiger (5) ein Temperatursensor (15) angeordnet, der die zum Druck des Kältemittels (8) proportionale Temperatur überwacht.The resistance heater ( 11 ) is switched off when the pressure of the refrigerant ( 8 ) exceeds a critical value during the drying phase. For this purpose, a temperature sensor ( 15 ) is arranged on the connecting pipe ( 14 ) between the compressor ( 6 ) and the condenser ( 5 ), which monitors the temperature proportional to the pressure of the refrigerant ( 8 ).
