Definitions
- the EP 3 190 224 A1 discloses a washer dryer with a heat pump module for generating the dryer air.
- the heat pump module is located above the tub, with the compressor and the blower being arranged on the side above the tub.
- the blower is located in front of the compressor in a free space that results between the curved area of the tub shell and the cuboid housing.
- the blower and the compressor are in a line one behind the other, so the housing must have a certain depth. This arrangement is not possible with a compact design of the washer-dryer.
- the approach presented here sets itself the task of creating a compact laundry treatment machine with a tub and heat pump module for generating the process air.
- a compact laundry treatment device is created in a simple manner, which is equipped with a heat pump module for generating the process air.
- the heat pump module is accommodated in a so-called standard housing. This is accomplished by placing the heat pump module in the free space above and to the side of the tub.
- the compressor is arranged on the side and in the rear area, behind the rear end wall of the tub, the blower.
- the position of the fan is such that it extends at least partially with the flat side along the end wall of the tub.
- the fan is preferably arranged between the rear wall and the rear wall of the housing because the installation space is particularly suitable for this. In the front area, the space is cramped because the front loading opening occupies a large proportion of the space between the front end wall and the front wall of the housing.
- the laundry treatment appliance also includes a control device (19) for activating and deactivating the actuators, ie at least the compressor and blower, for carrying out an automatic treatment process.
- the air inlet is arranged on or in the tub in the rear end wall in the lower area. This achieves a good, straight air flow through the inlet to the drum and through the drum if the drum rear wall is designed with holes or as a grid in some areas. A deflection of the air inside the tub does not take place here.
- the air inlet is preferably arranged below the height of the axis of rotation of the drum.
- the air outlet is arranged on or in the tub in the front, upper area of the front end wall. This ensures that the process air flows through the drum diagonally from the back to the front, rising at an angle.
- the outlet cannot be reached by the items of laundry moving in the drum and cannot be blocked by them because they always move downwards, i.e. away from the outlet, due to gravity. This ensures that the flow of the process air is not impeded.
- the fan is designed as a radial fan and includes a flow housing with a fan wheel adapted therein.
- the Flow housing has a diameter that corresponds to at least 4 times the axial extent of the fan, the flow housing being located in an extent perpendicular to the axial extent between the rear end wall of the tub and the rear housing wall.
- the fan is arranged in the rear area of the device housing in such a way that at least part of the flat flow housing is located between the rear end wall of the tub and the inside of the rear wall of the housing.
- the flow housing can preferably be designed with a diameter which is more than 6 times or 8 times the axial extent.
- the fan wheel is designed to be adapted to the geometry of the flow housing.
- the length of the flow housing is to be regarded as the axial extent, without the drive motor located on the shaft.
- the duct section of the module housing is flat, preferably having a rectangular cross section, with the heat exchanger arrangement being designed to match the cross section and being arranged in this duct section.
- the flat design is adapted so that the module housing with the heat pump does not protrude too much above the tub and does not exceed the space between the tub and the housing cover.
- a box-shaped deflection pipe is fitted downstream of the duct section in order to cause the process air flow to be deflected by approximately 70° to 100°, the deflection pipe having an approximately rectangular air inlet and a circular air outlet for connection to the fan.
- the rectangular inlet preferably has approximately the same cross section as the circular outlet of the box-shaped deflection tube.
- the box-shaped deflection tube is also preferably shaped in such a way that an approximately uniform cross section results for the process air flowing through. A preferred adaptation to the upper curvature of the tub results in the largest possible cross section being achieved. Overall, good flow behavior is achieved through the module, the channels and the drum.
- the laundry treatment appliance is preferably a washer-dryer, the housing being 55 cm to 65 cm wide, 55 to 70 cm deep and 85 to 95 cm high.
- the heat pump module as defined in the above examples, can be used particularly well for the washer-dryer.
- the housing dimensions that are already known on the market do not have to be changed in order to provide such a washer-dryer.
- the device does not have to be made higher than a comparable washer-dryer without a heat pump module arranged above the tub.
- the device 1 shows the laundry treatment appliance 1 according to the invention in a schematic sectional view.
- the device 1 is a washer-dryer 1 with a housing 2 and the units arranged therein for carrying out treatment programs.
- the unit with tub 4 and drum 3 rotatably mounted therein can be seen here.
- An inlet line 41 and an inlet valve 42 are provided for conveying the washing water, in order to feed water to the tub 4 or the drum 3 in a washing phase.
- the water is fed to the flushing-in dispenser 43 in order to conduct detergent stored there with the water flowing through the box into the tub 4.
- the flushing-in dispenser 43 is connected to the tub 4 by means of the inlet pipe 44 .
- the drain device 60 comprises a pump 61 and a drain line 62, the pump 61 being activated as required if this is provided in the course of an automatic washing process.
- the control device 90 is set up and programmed to activate and deactivate the actuators, ie the motor 70 for driving the drum in rotation, the inlet valve 42 and the pump 61 in order to carry out a treatment program.
- the washer-dryer 1 also includes a heat pump module 13, which is mounted in the housing 2 above the tub 4 and is used to generate a process air flow PL.
- the module 13 includes a refrigerant circuit in which refrigerant is in a line system with an evaporator 15, a compressor 14 ( 2 ) for compressing the refrigerant, a condenser 16 and a throttle (not shown) circulates, the heat exchanger containing the evaporator 15 and the heater containing the condenser 16 of the heat pump 13.
- the module 13 includes a housing 17 ( 2 ), in which a channel section 8 is incorporated and in which the evaporator 15 and the condenser 16 are mounted.
- the evaporator 15 and the condenser 16 are arranged in the duct section 8 in such a way that the moist process air PL from the outlet 47 of the tub 4 in the duct 8 first flows through the evaporator 15 so that it is dehumidified due to the cooling and the resulting condensation. It then flows through the downstream condenser 16, which acts as a heater and heats the process air PL, so that the heated process air PL is admitted through the air inlet 46 into the tub 4 and through openings 32 in the drum rear wall 31, the drum 3 and thus the textiles 10 to be treated is supplied. Any condensate that occurs is collected in the collecting pan 81 and conducted to the outlet 60 , 62 by means of the condensate line 82 .
- the outlet 47 of the tub 4 is preferably in the area of the loading opening at the front Front wall of the tub 4 or arranged in the tunnel-like passage area of the loading opening.
- the outlet 47 is connected to the heat pump unit 13 , in particular to the duct section 8 , by means of the line 96 .
- the function module 13 mounted above the tub 4 also includes the fan 9 which is driven by the motor 91 .
- the fan 9 includes a flow housing 93, inside which the fan wheel 92 is present.
- the housing 93 is flat and has a diameter that is at least four times larger than the axial length.
- the fan 9 is placed above the tub 4 in the appliance housing 2 in such a way that a part of the fan housing 93 extends in the gap between the rear wall 48 of the tub and the rear wall 21 of the housing.
- the fan can preferably be designed as a radial fan, preferably with curved blades, so that it causes a higher volume flow in a preferred direction than in the opposite direction of rotation.
- the 2 shows the washer-dryer 1 with the housing 2 partially open.
- the front wall 22 includes the loading opening, which is closed by the door 23 .
- the tub 4 is suspended or supported inside the housing 2 such that it can swing.
- the drum 3 (outlined in phantom) is rotatably mounted on a horizontal axis 33.
- the unit 13 for generating the process air PL is arranged above the tub 4 and completely inside the housing 2 .
- the unit 13 is attached to the housing 2 so that it does not vibrate with the tub 4 when the latter vibrates due to imbalance in the rotating drum 3 .
- the unit 13 includes a housing 17, which is used to position and preferably fix the compressor 14, the heat exchangers 15, 16, the lines 18 and the throttle (not shown).
- the housing 17 comprises the channel section 8 in the approximately central region, in which the heat exchangers 15, 16 are accommodated.
- the channel section 8 is provided downstream with the box-shaped deflection pipe 83 in order to deflect the process air flow running laterally to the rear.
- the fan 9 is connected to the circular outlet 83b of the deflection tube 83 and is located behind the housing 17 of the unit 13. It can be seen that the flat fan outlet 94 points downwards and is connected to the rear air line 95, which in turn leads to the air inlet 46 in or on the tub 4 opens.
- the fan housing 93 extends at least with the lower area and the outlet 94 in the space between the rear end wall 48 of the tub 4 and the rear wall 21 of the device housing 2.
- the housing 17 of the unit 13 comprises a base part 17b, in which the components 14, 15, 16, 18 of the heat pump are positioned and preferably fixed.
- the base part 17b is closed with a cover part 17a so that a channel section 8 is provided in which the heat exchangers 15, 16 are located.
- the box-shaped deflection pipe 83 is attached downstream of the channel section 8 in the direction of flow of the process air flow PL. This includes an approximately rectangular or rectangular flat inlet 83a and a circular outlet 83b. the outlet is designed or adapted for the connection of the fan 9 .
- the deflection tube 83 also serves to adapt the flat, rectangular outlet of the channel section 8 to the circular blower inlet.
- the rectangular inlet 83a has approximately the same cross section as the circular outlet 83b.
- the deflection tube is shaped in its extension between the inlet 83a and the outlet 83b in such a way that an approximately constant cross section results for the air flow. As a result, the process air is deflected without significant flow resistance. Roughly the same or roughly constant cross-section means that the maximum difference is 20%, preferably 10%.

Die
Der hier vorgestellte Ansatz stellt sich die Aufgabe, eine kompakte Wäschebehandlungsmaschine mit Laugenbehälter und Wärmepumpenmodul zur Erzeugung der Prozessluft zu schaffen.The approach presented here sets itself the task of creating a compact laundry treatment machine with a tub and heat pump module for generating the process air.
Erfindungsgemäß wird unter anderem diese Aufgabe durch ein Wäschebehandlungsgerät mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.According to the invention, this object is achieved, inter alia, by a laundry treatment appliance having the features of
Durch den hier vorgestellten Ansatz wird auf einfache Art und Weise ein kompaktes Wäschebehandlungsgerät geschaffen, welches mit einem Wärmepumpenmodul zur Erzeugung der Prozessluft ausgestattet ist. In einem sogenannten Standardgehäuse wird zusätzlich zu den Komponenten zum Waschen das Wärmepumpenmodul untergebracht. Das wird derart bewerkstelligt, dass das Wärmepumpenmodul in den Freiraum oberhalb und seitlich des Laugenbehälters platziert wird. Dabei ist der Kompressor seitlich und im hinteren Bereich, hinter der hinteren Stirnwand des Laugenbehälters das Gebläse angeordnet. Das Gebläse ist hinsichtlich seiner Position so ausgerichtet, dass es sich zumindest teilweise mit der flachen Seite entlang an der Stirnwand des Laugenbehälters erstreckt. Dadurch wird eine kurze Bauweise für die Anordnung aus Kompressor erreicht. Bevorzugt ist das Gebläse zwischen der hinteren und der Rückwand des Gehäuses angeordnet, weil der Bauraum dazu besonders geeignet ist. Im vorderen Bereich ist der Bauraum beengt, weil die frontseitige Beladungsöffnung einen großen Anteil des Raumes zwischen vorderen Stirnwand und der Frontwand des Gehäuses einnimmt.With the approach presented here, a compact laundry treatment device is created in a simple manner, which is equipped with a heat pump module for generating the process air. In addition to the washing components, the heat pump module is accommodated in a so-called standard housing. This is accomplished by placing the heat pump module in the free space above and to the side of the tub. The compressor is arranged on the side and in the rear area, behind the rear end wall of the tub, the blower. The position of the fan is such that it extends at least partially with the flat side along the end wall of the tub. As a result, a short construction for the arrangement of the compressor is achieved. The fan is preferably arranged between the rear wall and the rear wall of the housing because the installation space is particularly suitable for this. In the front area, the space is cramped because the front loading opening occupies a large proportion of the space between the front end wall and the front wall of the housing.
Das Wäschebehandlungsgerät umfasst ferner eine Steuereinrichtung (19) zum Aktivieren und Deaktivieren der Aktoren, also zumindest Kompressor und Gebläse, zur Durchführung eines automatischen Behandlungsablaufs.The laundry treatment appliance also includes a control device (19) for activating and deactivating the actuators, ie at least the compressor and blower, for carrying out an automatic treatment process.
In einer vorteilhaften Ausführung ist am oder im Laugenbehälter der Lufteinlass in der rückseitigen Stirnwand im unteren Bereich angeordnet. Damit wird eine gute und geradlinige Luftströmung durch den Einlass zur Trommel und durch die Trommel erreicht, wenn die Trommelrückwand mit Löchern oder bereichsweise als Gitter ausgebildet ist. Eine Umlenkung der Luft innerhalb des Laugenbehälters findet hierbei nicht statt. Bevorzugt ist der Lufteinlass unterhalb der Höhe der Drehachse der Trommel angeordnet.In an advantageous embodiment, the air inlet is arranged on or in the tub in the rear end wall in the lower area. This achieves a good, straight air flow through the inlet to the drum and through the drum if the drum rear wall is designed with holes or as a grid in some areas. A deflection of the air inside the tub does not take place here. The air inlet is preferably arranged below the height of the axis of rotation of the drum.
In einer weiteren, vorteilhaften Ausführung ist am oder im Laugenbehälter der Luftauslass im vorderen, oberen Bereich der frontseitigen Stirnwand angeordnet. Dadurch wird erreicht, dass die Prozessluft durch die Trommel diagonal von hinten nach vorn schräg ansteigend strömt. Der Auslass wird von den in der Trommel bewegten Wäschestücken nicht erreicht und kann nicht durch diese verstopft werden, weil sie sich aufgrund der Schwerkraft stets nach unten, also vom Auslass entfernt, bewegen. Dadurch ist sichergestellt, dass die Strömung der Prozessluft nicht behindert wird.In a further advantageous embodiment, the air outlet is arranged on or in the tub in the front, upper area of the front end wall. This ensures that the process air flows through the drum diagonally from the back to the front, rising at an angle. The outlet cannot be reached by the items of laundry moving in the drum and cannot be blocked by them because they always move downwards, i.e. away from the outlet, due to gravity. This ensures that the flow of the process air is not impeded.
In einer insgesamt zweckmäßigen Ausführung ist der Lüfter als Radiallüfter ausgebildet und umfasst ein Strömungsgehäuse mit einem darin angepasstem Lüfterrad. Das Strömungsgehäuse weist einen Durchmesser auf, der zumindest das 4-Fache der axialen Erstreckung des Lüfters entspricht, wobei sich das Strömungsgehäuse in Erstreckung senkrecht zur axialen Erstreckung teilweise zwischen der rückseitigen Stirnwand des Laugenbehälters und der Gehäuserückwand befindet. Anders ausgedrückt, der Lüfter ist derart im hinteren Bereich des Gerätegehäuses angeordnet, dass sich zumindest ein Teil des flachen Strömungsgehäuses zwischen der rückseitigen Stirnwand des Laugenbehälters und der Innenseite der Gehäuserückwand befindet. Bevorzugt kann das Strömungsgehäuse mit einem Durchmesser ausgebildet sein, der mehr als das 6- fache oder 8-fache der axialen Erstreckung aufweist. Das Lüfterrad ist dabei entsprechend der Geometrie des Strömungsgehäuses angepasst ausgebildet. Als axiale Erstreckung ist dabei die Länge des Strömungsgehäuses anzusehen, ohne den an der Welle befindlichen Antriebsmotor.In an embodiment that is expedient overall, the fan is designed as a radial fan and includes a flow housing with a fan wheel adapted therein. The Flow housing has a diameter that corresponds to at least 4 times the axial extent of the fan, the flow housing being located in an extent perpendicular to the axial extent between the rear end wall of the tub and the rear housing wall. In other words, the fan is arranged in the rear area of the device housing in such a way that at least part of the flat flow housing is located between the rear end wall of the tub and the inside of the rear wall of the housing. The flow housing can preferably be designed with a diameter which is more than 6 times or 8 times the axial extent. The fan wheel is designed to be adapted to the geometry of the flow housing. The length of the flow housing is to be regarded as the axial extent, without the drive motor located on the shaft.
In einer weiteren, insgesamt zweckmäßigen Ausführung ist der Kanalabschnitt des Modulgehäuses flach ausgebildet, bevorzugt einen rechteckigen Querschnitt aufweisend, wobei die Wärmetauscheranordnung entsprechend dem Querschnitt angepasst ausgebildet und in diesem Kanalabschnitt angeordnet ist. Die Flache Ausführung ist dazu angepasst, dass das Modulgehäuse mit der Wärmepumpe oberhalb des Laugenbehälters nicht zu stark aufträgt und den Bauraum zwischen Laugenbehälter und Gehäusedeckel nicht überschreitet. Dem Kanalabschnitt stromabwärts ist ein kastenförmiges Umlenkrohr angebracht, um eine Umlenkung des Prozessluftstromes etwa um 70° bis 100° zu bewirken, wobei das Umlenkrohr einen etwa rechteckigen Lufteintritt und einen kreisförmigen Luftaustritt zur Anbindung an den Lüfter aufweist.In a further embodiment that is expedient overall, the duct section of the module housing is flat, preferably having a rectangular cross section, with the heat exchanger arrangement being designed to match the cross section and being arranged in this duct section. The flat design is adapted so that the module housing with the heat pump does not protrude too much above the tub and does not exceed the space between the tub and the housing cover. A box-shaped deflection pipe is fitted downstream of the duct section in order to cause the process air flow to be deflected by approximately 70° to 100°, the deflection pipe having an approximately rectangular air inlet and a circular air outlet for connection to the fan.
Der rechteckige Einlass weist dabei bevorzugt etwa den gleichen Querschnitt auf, wie der kreisförmige Auslass des kastenförmigen Umlenkrohres. Das kastenförmige Umlenkrohr ist ferner bevorzugt derart geformt, dass sich ein etwa gleichmäßiger Querschnitt für die durchströmende Prozessluft ergibt. Eine bevorzugte Anpassung an der oberen Krümmung des Laugenbehälters bewirkt, dass ein möglichst großer Querschnitt erreicht wird. Insgesamt wird ein gutes Strömungsverhalten durch das Modul, die Kanäle und die Trommel erreicht.The rectangular inlet preferably has approximately the same cross section as the circular outlet of the box-shaped deflection tube. The box-shaped deflection tube is also preferably shaped in such a way that an approximately uniform cross section results for the process air flowing through. A preferred adaptation to the upper curvature of the tub results in the largest possible cross section being achieved. Overall, good flow behavior is achieved through the module, the channels and the drum.
Das Wäschebehandlungsgerät ist bevorzugt ein Waschtrockner, wobei das Gehäuse 55 cm bis 65 cm breit, 55 bis 70 cm tief und 85 bis 95 cm hoch ist. Für den Waschtrockner ist das Wärmepumpenmodul, wie es in den oben genannten Beispielen definiert ist, besonders gut einsetzbar. Die bereits am Markt bekannten Gehäusemaße müssen nicht verändert werden, um einen solchen Waschtrockner bereitzustellen. Insbesondere muss das Gerät nicht höher ausgebildet werden, als ein vergleichbarer Waschtrockner ohne über dem Laugenbehälter angeordnetem Wärmepumpenmodul.The laundry treatment appliance is preferably a washer-dryer, the housing being 55 cm to 65 cm wide, 55 to 70 cm deep and 85 to 95 cm high. The heat pump module, as defined in the above examples, can be used particularly well for the washer-dryer. The housing dimensions that are already known on the market do not have to be changed in order to provide such a washer-dryer. In particular, the device does not have to be made higher than a comparable washer-dryer without a heat pump module arranged above the tub.
