Definitions
- the invention relates to a cleaning device for a disposed within a process air circuit of a household laundry dryer component, in particular for a NEN heat exchanger, specified in the preamble of claim 1.
- Such a cleaning device can already be seen from EP 0 468 573 A1 as known, in which a designed as a working medium evaporator heat exchanger is disposed within a process air circuit of a heat pump tumble dryer.
- the cleaning device comprises a brush device with a flat brush, which can be reciprocated by means of an electric motor and a crank on the front side of the heat exchanger and forth.
- a disadvantage of this known cleaning device is the fact that the flat brush can reliably remove the lint from the fins of the heat exchanger from the front side of the heat exchanger only over a limited depth.
- the lint taken up by the bristles and removed from the heat exchanger are relatively easily fixed inside the brush, as a result of which the cleaning result - in particular with longer service lives of the flat brush - is greatly impaired.
- the brush device comprises at least one round brush, which is rotatable about a rotation axis by means of a rotary drive.
- the bristles or the like can be moved at a relatively high rotational speed, so that they-unlike the bristles of a flat brush-can sink far deeper into the corresponding component.
- the lint deposited relatively deep within the component is reliably conveyed to the surface and further away from the component, so that overall a significantly better cleaning result can be achieved by a round brush.
- the rotational movement of the round brush also ensures that the lint removed from the component does not adhere to the bristles or the like and thus remain within the round brush, but rather are transported to the outside due to the flying force when rotating the round brush. As a result, sticking and a lapse of the cleaning effect are avoided.
- the direction of rotation of the round brush adjustable in dependence on its translatory movement direction. This makes it possible to choose the direction of rotation of the bristles - depending on the translational movement of the round brush - so that the lint be transported from the interior of the component or the heat exchanger to the outside. It is also advantageous if the bristles or the like of the round brush can dip into the working medium evaporator at least as far as working fluid pipes. Experience has shown that in the area of the working medium pipes, a particularly large amount of condensate of the moist, warm process air is deposited, as a result of which large quantities of lint are deposited on the working medium pipes.
- the cleaning cycles of the cleaning device can be determined in a simple manner by measuring a specific pressure loss via a pressure sensor within the process air circuit. Such a pressure loss occurs when a certain amount of lint has deposited on the component through which the process air flows.
- the round brush can be cleaned in a particularly reliable manner of lint or the like dirt when a comb is provided, through which the bristles or the like of the rotating round brush are pulled through.
- the condensate of the working-medium evaporator or the condensation device which is present without any problems, is used for this purpose.
- FIG. 1 shows a schematic side view of a heat exchanger arrangement arranged within a section of a duct of a process air cycle of a domestic laundry drier with a working medium evaporator, on the front side of which - viewed in the direction of flow of the process air circuit - a cleaning device can be seen schematically;
- Figure 2a is a schematic sectional view through the channel of the process air circuit along the line Il a - Il a Fig. 1.
- FIG. 2b shows a schematic sectional view through the brush device of the cleaning device arranged in front of the working medium evaporator along the line IIb-IIb in FIG. 2a;
- FIG. 3 shows a schematic side view of the round brush of the brush device which is driven by means of a motor with a countershaft and which dips into the heat exchanger at least approximately as far as the working medium tubes of the working medium evaporator;
- Fig. 4 is a schematic side view and a schematic plan view of a arranged within the process air circuit of the household Waechetrockners, designed as a condensation heat exchanger and the - viewed in the flow direction of the process air cycle - arranged in front of it
- a heat exchanger arrangement 14 which in the present exemplary embodiment comprises a working medium evaporator 16 and a working medium condenser or condenser 18.
- a lint filter 20 is arranged in the flow direction of the process air cycle before the Exchanger arrangement 14.
- a large part of the lint or the like dirt particles can be deposited, which are transported via the humid in this area, led out of the laundry drum of the household laundry drier not shown process air.
- the separated fluff are to be removed from the lint filter 20 in a known manner.
- the moist moist process air in the region of the lint filter 20 is dehumidified by means of the working medium evaporator 16, it being possible to pump off the resulting condensate via an outlet opening 22 and an outlet line 24 by means of a pump (not shown).
- a receiving tray 26 is arranged, via which lint or the like dirt particles are collected.
- the receiving tray 26 is accordingly to be manually emptied from time to time.
- the cool and dry air downstream of the working medium evaporator 16 is then reheated by the working fluid condenser 18 in order to be able to re-direct the process air flow into the washing drum by means of a blower (not shown).
- a cleaning device with a brush device 28 is disposed within the process air circuit, which serves to remove lint or the like dirt that have come despite the lint filter 20 to the working medium evaporator 16 and deposited there.
- FIGS. 2 a and 2 b which show, in a schematic sectional view along the line IIa-IIa in FIG. 1 or along the line IIb-IIb in FIG. 2a, the brush device 28 arranged upstream of the working-medium evaporator 16, FIG. it can be seen that this comprises a round brush 30 as an essential element.
- This round brush 30 is rotatably driven about a rotation axis R and includes a plurality of bristles, small lobes or the like.
- the round brush 30 is to be moved by means of a drive mechanism 32 completely along an end face 34 of the working medium evaporator 16. In order to make this possible, bulges 36 (FIG.
- the round brush 30 can dip, into which the round brush 30 can dip, are introduced within the channel 10 of the process air circuit.
- the round brush 30 can be moved so far outward that the end face 34 of the working medium evaporator 16 is cleaned equally well at each point.
- the round brush 28 is thereby by means of a guide device 38 of the drive mechanism 32nd moved in a translational movement along the end face 34 of the working medium evaporator 16.
- the drive mechanism 32 comprises a toothed rack drive 40, which is recognizable in further detail in particular in conjunction with FIG. 3, with a toothed rack 42 along which the round brush 32 is moved in a translatory manner.
- Fig. 3 in which in a schematic side view, the front side immersed in the working medium evaporator 16 round brush 30 can be seen, it is also seen that the bristles, cloths or the like can dive into the working medium evaporator 16 at least up to working fluid tubes 44.
- a plurality of slats 46 running parallel to one another can be seen from FIG. 3, which are to be cleaned from the end face 34 by means of the round brush 30.
- the round brush 30 can also dip deeper into the working medium evaporator 16 beyond the working medium pipes 44.
- a motor 48 is provided with a countershaft, which forms the rotary drive of the round brush 30.
- the rotation axis R can pass through a wall 56 of the channel 10, a slot is provided within this, which is to be closed by means of a seal 58.
- the seal 58 ensures that the rack drive 40 can not be affected by lint.
- the cleaning device comprises a recognizable in Fig. 3 comb 60, with which the round brush 30 can be cleaned of lint or the like dirt.
- the comb 60 engages with the round brush 30 as soon as it reaches an end position within the bulges 36.
- the fins 46 of the working medium evaporator 16 and / or the round brush 30 with the by the Hästoff- Evaporator 16 sprayed condensate obtained.
- a spray device not shown, which is supplied in the region of the outlet line 24 with condensate.
- a different cleaning liquid instead of the condensate.
- the condensate serves on the one hand to dissolve and to transport the lint away from the lamellae 46, and on the other hand to remove the lint from the round brush 30.
- the round brush 30 is preferably operated in a direction of rotation shown by the arrow 62, in which the bristles engaged with the lamellae 46 are in the same Direction to be moved as the round brush 30 itself. If the translational movement direction accordingly - opposite to the arrow 64 - changed, as well as the rotation direction of the round brush 30 is set in the opposite direction, depending thereon.
- the cleaning process is preferably automatically initiated either towards the end of each drying process of the household tumble dryer, after a certain number of drying operations or as a function of a certain pressure loss of the process air cycle.
- a sensor 66 (FIG. 1) is provided within the channel 10, with which a pressure loss within the channel 10 caused by the deposition of lint can be measured.
- FIG. 4 a shows a schematic plan view or a schematic side view of the channel 10 of the process air circuit, in which, however, a heat exchanger designed as a condensation device 66 is alternatively provided.
- the channel 10 is shown cut open both in the plan view and in the side view.
- the condensation device 66 comprises a plurality of heat exchanger plates 68, through which the moist-warm process air reaching from the laundry drum of the domestic laundry drier flows through the lint filter 20 and can cool and condense for drying.
- a plurality of parallel and in the flow direction extending slats 72 are arranged, which project beyond the heat exchanger plates 68 towards the front and extend to the rear by a small longitudinal displacement up into the heat exchanger plates 68.
- the bristles or the like of the round brush 30 can dive into the condenser 66 at least up to the rear end of the fins 72, so as to achieve a uniform cleaning over the entire depth of the fins 72.
- the lamellae 72 are to be cooled via the condensation device 66.
- condensate also forms in the region of the lamellae 72, so that the lint on it can be easily removed.
- the round brush 30 can dip so far into the condensation device 66 that the heat exchanger plates 68 are also cleaned.
