- EP 1 961 853 A1 discloses a clothes dryer with a heat pump. During a drying process, that part of an air flow path that is between a rotating laundry container and an evaporator is opened, such that air in the rotating laundry container circulates through the air flow path. During cooling of the location where the tumble dryer is located, a bleed air flow path opened from the portion of the air flow path that is between the rotating laundry bin and the evaporator to an outside of the clothes dryer opens air an air inlet is introduced, is passed through the evaporator and is blown out of the discharge air flow path and at the same time a condenser is cooled by a cooling device.
- a household appliance comprising a first heat exchanger and a second heat exchanger, which are arranged one behind the other in an air flow channel with respect to its flow direction, and a cleaning device for cleaning the first heat exchanger with cleaning liquid, wherein in the air flow channel between the first heat exchanger and the second heat exchanger, a Strömungsleit MUST is present, which has at least one planar, between the first heat exchanger and the second heat exchanger at least approximately horizontally aligned flow guide. Furthermore, the at least one flow-guiding element can in particular be located above one Bottom of the air flow channel may be arranged.
- This household appliance has the advantage that a decrease in the entrained water between the two heat exchangers can be reduced or even partially prevented by the flow guide, whereby the second heat exchanger can be cleaned by means of entrained water at a higher level than without the Strömungsleit Vietnamese.
- the flow guide can cause water droplets approaching from above to fall or the like. in the region of the flow guide a higher counterforce due to a back pressure o.ä. experienced as in free fall, so that a range of water droplets in the horizontal direction is increased. Also occurs the effect that settle the water droplets on the flow guide and there can produce a water film, which is pressed by the flowing process air in the direction of the second heat exchanger.

- the cleaning fluid may be or have water.
- the cleaning fluid may include or be fresh water and / or condensate.
- the water may have additives, for example detergents.
- An at least approximately horizontally aligned flow-guiding element may, in particular, be understood as meaning a planar element which is oriented horizontally or predominantly horizontally in the direction from the evaporator to the condenser.
- a predominantly horizontal orientation can be understood to mean an orientation which does not deviate more than 45 ° from the horizontal (in both directions, ie not more than + 45 ° or -45 °). The direction can be measured in particular between the end points of the flow guide.
- That the at least one flow guiding element above a bottom of the air flow menkanals includes, in particular, that it is spaced from this floor. Consequently, there is a flow cross section for the process air between the bottom of the air flow channel and the flow guide element (in the case of a plurality of flow guide elements arranged at a distance above one another between this base and the lowest flow guide element adjacent thereto).

- the first heat exchanger corresponds to an evaporator of the heat pump
- the second heat exchanger corresponds to a condenser of the heat pump
- At least one flow guide is strip-shaped or strip-shaped and extends in relation to its longitudinal extent, in particular transversely to the process air channel. This allows a particularly simple possibility of influencing the air flow and movement of the water over a large - in particular full - width of the air flow channel.
- a flow-guiding element can be designed as a straight, flat strip of material.
- substantially the entire width may be understood to mean, in particular, the entire width or at least 90% of the entire width.

- the flow guide structure can be made simpler and more effective.
- the first heat exchanger can rest at the same height as the second heat exchanger, higher than the second heat exchanger or lower than the second heat exchanger. It is also an embodiment that the first heat exchanger has a lower height than the second heat exchanger. This makes it possible to achieve at least approximately the same installation height of the two heat exchangers.

- a plurality of flow guide elements can be arranged between the floor and the ceiling.
- the plurality of flow guide elements may have the same or a different distance from each other and / or to the floor and / or to the ceiling.

- a first open end face of at least one air duct facing an air outlet side of the first heat exchanger and a second open end face of the at least one air duct facing an air inlet side of the second heat exchanger This results in the advantage that a particularly straight air duct between the two heat exchangers can be implemented.
- the Strömungsleit Quilt in particular the first open end face - directly, in particular at a distance of not more than ten millimeters, in particular not more than five millimeters, adjacent to the air outlet side of the first heat exchanger and is spaced therefrom. Such a distance facilitates easy insertion of the Strömungsleit Nursing while effectively reducing a drop in height of the water droplets.
- the Strömungsleit Quilt Quilt especially the second open end face - immediately, in particular at a distance of not more than ten millimeters, in particular not more than five millimeters, adjacent to the air inlet side of the second heat exchanger and is spaced therefrom. Such a distance also facilitates easy insertion of the flow guide structure while effectively reducing a drop in height of the water droplets.
- the flow-guiding structure or at least one flow-guiding element can touch at least one heat exchanger.
- the flow-guiding structure has at least two adjacently arranged arrangements of in each case at least two circumferentially closed, superimposed air-conducting channels.
- crossflows that increase a waterfall due to a path extension for the water droplets can be suppressed.
- the resulting stronger channeling of air currents can also increase airspeed, further suppressing a waterfall.
- the air ducts have a rectangular cross section when viewed in the flow direction. This results in the advantage that the flow structure can be implemented by a rectangular arrangement of flat planar components or partial areas, which allows a particularly simple and inexpensive production. This is especially true in a multi-part structure of the flow structure.
- the flow guide structure or the air guide channels has a grid-like basic shape with the air guide channels as the grid openings. It is yet another embodiment that the first heat exchanger and the second heat exchanger are arranged on a common support - in particular floor - and the flow guide is used as a prefabricated component between the first heat exchanger and the second heat exchanger.
