Definitions

the invention relates to a lint filter device for an air flow in a household clothes dryer or a household washer dryer.
a heated gas stream preferably an air stream
a heated gas stream is usually brought into contact with the laundry to be dried in order to be contained in the laundry Remove moisture.
the lint carried by the air flow can become then disadvantageously deposit or even fix elsewhere. Therefore
fluff filter devices are provided, which are used to remove fluff the airflow can be removed.
the retained fluff is also laying the filter device and must be removed. This is usually already necessary after each drying process and affects the ease of use for the operator considerably.
DE 90 00 624 U1 proposes an endless filter belt as a filter element, which also poses the problem that with a straight air flow one strand of the filter belt is flowed through from the outside in and the other Strand from the inside out and thus fluff that is not retained by the first strand were able to put on the second strand inside.
a fluff on the inside of the filter belt again has the disadvantage that the removal of lint is difficult there and especially that in this case the lint must be removed from both the inside and the outside and thus one more complex device is required.
DE 195 06 214 A1 discloses a textile cleaning system with a lint filter, in which a single-layer filter layer from below of the air flow to be cleaned flows through and in which a slide is moved back and forth at the bottom of the filter layer, which pushes the lint collected there so that it goes into a collecting container falling off.
a complex linear guide is disadvantageous of a slider is necessary, whereby the fluff alone does not safely remove the fluff from the filter surface can be removed, but still the participation of Fluff, however, requires very little weight.
the invention has for its object to provide a lint filter device which removes the filtered fluff from the filter with simple means can, the space requirement is kept low and the air flow straight through the filter element can be performed.
this object is achieved by a lint filter device for an air flow solved in a household clothes dryer with an endless circulation element, the Movement path is crossed twice by the air flow and that a fitter element has in a filter phase at the location of the first cross between airflow and Movement path can be arranged, the portion of the circulating element, the in the filter phase at the location of the second intersection between air flow and trajectory is designed in such a way that little or no fluff remains on it, and this in a cleaning phase by a circular movement of the circulating element on a device for removing lint from the surface of the filter element can be passed.
the air flow can in this way straight through the filter device are passed with the circulating element, the lint, which from the Filter element can not be retained, not on the inside of the circulation element get stuck.
the fluff must therefore advantageously only from one side of the circulating element be removed, so that the effort for the necessary device is low.
encircling elements have the advantage that for storage in the case of rigid revolving elements, in particular in the case of flexible revolving elements rotatably mounted deflection bodies are sufficient, which are much more advantageous than Bearings for linear movements are.
the filter element In the filter position, the filter element should cover the entire cross section of the air flow cover so that no fluff can get past the side. Since at Guide the filter element past the device for removing the lint the filter element at least partially clears the air flow, removing the lint in Operational phases of the tumble dryer happen in which there is either no fluff in the air flow or in which no air flow is generated, so that no fluff be brought up. This can be at the end of a drying process, for example.
the section of the circulation element that is in the filter phase at the location of the second intersection located between airflow and trajectory, for example, with large Openings are provided through which fluff can pass without getting caught.
the section can be designed, for example, as a wide-mesh network or grid be, the elements between the stitches in particular particularly thin and are smooth so that no fluff gets caught on it.
large opening can be provided, for example, over almost the entire Width of the circumferential element extends and only on the sides of thin edge strips is limited or cords that close the circulating element.
the device for removing lint from the surface of the Filter element a scraper.
This can be set up easily and without moving parts become.
the fluff can be changed by moving the Circulation element are removed.
the wiper guides Lint removed from the surface of the filter element as it passes a container.
the removal of the fluff and its transportation into a collecting container can therefore be carried out in one operation.
a collection container, in where the lint can be collected can also be used with other types of devices be provided for removing fluff.
the capacity of the collecting container can be chosen so large that it is only emptied at longer intervals must become.
such a collecting container is advantageously placed in or arranged on the dryer that it is easily accessible for the operator and / or is removable. He can do this, for example, from the front of the dryer be accessible.
the scraper and the collecting container is advantageously arranged at the bottom, so that the transport of the removed fluff in the collecting container is supported by gravity.
a level indicator or a warning when a certain level is exceeded Fluff stands are provided.
the lint removed from the filter element can also be mixed with a liquid rinsed out of the tumble dryer in particular into a waste water connection become.
the condensate can be used as the rinsing liquid.
the device for removing lint from the surface of the filter element can also be a suction device with which the lint through suction lines easier can also be transported to locations that are further away from the filter element.
the circulating element can be a band.
the belt can be used for deflection devices for storage being held.
the deflection devices can roll, roll or in the simplest case are bars on which the tape slides and which advantageously with are provided with a low-friction surface.
With rotating deflection devices the belt can also be driven in the circumferential direction, with the drive at least one rotatable deflection device and simple for further mounting non-rotatable deflection devices can be provided. Nevertheless, can the belt is also driven in the direction of rotation by devices that are not for Redirect or hold.
the drive for the circulating element can be from a control device can be controlled for the household clothes dryer.
the belt can be spanned by two rollers around which it runs can and at least one of which serves to drive the belt.
the space requirement is very high small and only slightly larger than, for example, for a single-layer filter.
Rotatable Deflection devices for driving the belt can drive devices such as Teeth or a friction or rubber surface to connect to the tape improve.
the band can in turn have devices that engage the Driver devices of driving deflection devices facilitate, such as Openings through which teeth can protrude and with which the belt can also can be guided laterally.
the tape can be made from a flexible support such as a wide-meshed network, to which no fluff is attached can and that is covered with a filter element over a certain section.
a flexible and tensile filter element at two ends by means of a Section of lint-repellent material connected and closed to form a circulating element become.
the circulating element can also be a rotatable drum. This can be done easily be stored with one or two rotary bearings, the drive via the axis of rotation can be done.
Lint removed from the surface of the filter element can also be cleaned with a Liquid can be wetted. So that the fluff can be compacted or you Volume can be greatly reduced.
the collecting container can thus be made smaller or the time intervals after which it is emptied become longer got to.
the lint filter device has a condensation device for moisture contained in the air flow, can advantageously accumulate condensate in the condensation device for wetting the removed fluff can be used. With the liquid, too the filter element can be wetted to increase the filter effect.
the household tumble dryer in which the lint filter device is used is one Movable device, which at the end of a drying process by the operator is necessarily operated, this movable device can advantageously be operatively connected to the peripheral element, so that when they are actuated, the Passing the filter element on the device for removing lint causes.
This device can in particular be the loading door that can be removed at the end the laundry has to be opened anyway.
a backup is provided, which prevents the door from opening during operation, is on this Way also ensures that the filter element is not moved out of the air flow, as long as fluff is still carried in by the air flow. Furthermore, on this way the drive for the circulating element is omitted.
FIG. 1 and 2 is a schematic sectional side view through an inventive Lint filter device 1 for an air stream S carrying fluff 5, 5 'in a household clothes dryer shown.
this household clothes dryer is usually a Airflow S generated and passed over the laundry to be dried, the laundry moisture withdrawn and thereby entraining fluff 5, 5 'that settle elsewhere can and must therefore be removed.
the air flow S enters the lint filter device from the right 1 and is guided horizontally and straight in an air duct 8.
the deflection device 9 is rotatable, at least one of them in the direction of rotation can be driven.
a scraper 6 is arranged so that it knife-like upper edge just above the surface of the circulating element 2.
Das Profile of the scraper 6 runs from the upper edge to a lower edge, which is above a open top collecting container 7, which ends from outside the household clothes dryer can be removed.
the wiper 6 extends perpendicular to the drawing plane parallel to the lower deflection device 9 over the entire, exposed to the air flow Width of the circulation element 2.
the circulating element 2 is formed by a carrier on which fluff 5, 5 'does not or can only set very bad. Over a section of the circulating element 2, the corresponds to the flow cross section of the air duct 8, the circulation element 2 has flexible filter element 3, for example a filter fabric.
the circulation element can consist of a wide-meshed network of thin, smooth threads, which over one Section is occupied with the filter element 3, instead of the wide-mesh network also two endless pull straps can be easily provided between them the filter element 3 is clamped.
the lint filter device 1 is shown in the filter phase in which the filter element 3 is arranged so that it covers the entire cross section of the air flow S extends, which carries fluff 5, 5 'after its contact with the laundry.
the fluff 5, 5 ' the fluff 5 is retained by the filter element 3, collect on its surface and move it over time.
the other lint 5 'that is not can be retained by the filter element 3, then pass through the section 4 of the circulation element 2, which in the filter phase in the flow direction behind the filter element 3 lies.
the 2 shows the lint filter device 1 during the cleaning phase, in which advantageously no air flows through the lint filter device 1.
the rotating element 2 is turned in by turning one or both deflection devices 9 Circulation direction moves, so that the filter element 3 passes the wiper 6 becomes.
the wipers 6 remove the lint 5 from the surface of the filter element 3 lifted off and passed into the collecting container 7.
the collecting container 7 is dimensioned so large that it can absorb the fluff 5 during a series of drying operations accumulate so that it does not have to be emptied after each drying cycle.
At least one deflection device 9 with a The loading door of the household clothes dryer is operatively connected so that the cleaning process without its own drive and control automatically after each drying cycle is performed when the operator removes the laundry from the loading door opens.
