Definitions

  • the present invention relates to a filter for eliminating impurities present in the air jet of a clothes dryer according to the preamble of claim 1.
  • the present invention also relates to a clothes dryer equipped therewith.
  • Clothes dryers are per se known, and typically comprise a drum containing laundry to be dried by an air jet generated by a fan and heated by an electric resistor or by a condenser device in a machine fitted with a heat pump.
  • the hot air jet flows through the laundry in the drum, thereby subtracting moisture therefrom, and then flows through a filter that eliminates any impurities present in the air j et.
  • Said air jet also flows through a heat exchanger, where it cools down through the effect of thermal exchange with colder environmental air, thus condensing and yielding water, which flows into a collection tank usually located in the lower part of the machine; from the collection tank, the water is conveyed by a pump into a removable container typically arranged in the upper part of the machine, in a position easily accessible to a user, who can then periodically remove and empty said container.
  • clothes dryers known in the art may not include a collection tank; in such cases, they are only equipped with the container for collecting the condensed water, said container being usually positioned in the lower part of the machine.
  • the clothes dryers known in the art comprise:
  • said clothes dryers may also comprise:
  • a filter for eliminating air jet impurities whose structure contains a filtering element.
  • a filter usually has an aperture that makes it easier for the entire air jet coming from the drum to enter the filter, so as to obtain the elimination of any impurities present in said air jet.
  • said filter is generally so shaped that it can be placed into a suitable housing of the clothes dryer.
  • a further drawback of prior-art filters is that, even when said filters can be opened in order to remove the collected impurities, such task is often difficult, in particular because it is difficult to separate the closing means used for holding the filters in the closed condition.
  • FIG. 1 reference numeral 100 designates as a whole a clothes dryer according to the present invention.
  • the clothes dryer 100 comprises a frame 101 that houses a drum 102 adapted to contain laundry (not shown) to be dried, said drum 102 being accessible from the outside through a door 103 usually fitted with sealing gaskets (not shown).
  • the clothes dryer 100 also comprises first means 104, 105 for delivering heated air into said drum 102.
  • said first means may comprise an electric resistor 104 and a fan 105 (as shown in Fig. 1 ); or, in the case of a clothes dryer equipped with a heat pump (not shown in the drawings), said first means may comprise a condenser and a fan.
  • the clothes dryer 100 further comprises second heat exchanger means 106 crossed by the air coming from the drum 102; preferably, said second means comprise an exchanger 106, where the humid air coming from the drum 102 condenses.
  • the clothes dryer 100 also comprises at least one container 107 for collecting the condensed water produced by said second heat exchanger means 106.
  • the humid air flows through a filter 1 adapted to eliminate the impurities present in the air jet; the hot humid air is then cooled by thermal exchange with colder air (normally at ambient temperature) in said second means 106, said colder air being possibly conveyed by a second fan (not shown in Fig. 1 ).
  • the condensed water present in a collection tank 108 is delivered by a pump 109 towards the container 107, wherein it is collected. It is however clear that the container 107 may also be arranged in a lower part of the clothes dryer 100 according to the present invention; in such a case, the clothes dryer 100 may even lack the collection tank 108 and/or the pump 109.
  • the clothes dryer 100 may include additional components which have been omitted in the present description for simplicity.
  • Figs. 2a and 2b respectively show a first and a second perspective views of the filter 1 according to the present invention.
  • the filter 10 comprises a first frame 10 and a second frame 20 which enclose a filtering element F (schematically shown in Fig. 2a only), said first 10 and second 20 frames being connected together along respective first edges 11, 21 adj acent to each other, so that the filter 1 can be opened like a book.
  • connection along said first edges 11, 21 substantially allows said first 10 and second 20 frames to rotate about an axis X, indicated in Fig. 2b by means of a dashed-dotted line.
  • the particular shape of the filter 1 according to the present invention facilitates the task of removing the impurities collected inside said filter 1; in fact, the possibility of opening the filter 1 like a book allows the filtering element F to be easily extracted for reconditioning, in particular by removing the impurities trapped therein.
  • first 10 and second 20 frames comprise respective second edges 12, 22 fitted with straps 13, 23, each one of said straps 13, 23 comprising:
  • FIG. 2a said closed condition of the filter 1 is shown in Fig. 2a
  • Fig. 2b shows the filter 1 in an open condition.
  • FIG. 2a shows that the first strap 13 comprises a first hole 14 and the second strap 23 comprises a second hole 24.
  • the above-described particular design of the filter 1 also facilitates the extraction of the filter 1 from the respective housing in the clothes dryer 100, as well as the tasks of opening the filter 1 and removing the impurities collected inside the filter 1.
  • the holes 14, 24 of said straps 13, 23 allow the user to put his/her fingers into them in order to extract the filter 1 from the clothes dryer 100 and to disengage the coupling means 15, 25 for opening the filter 1.
  • the user will just have to move the holes 14, 24 apart so as to disengage said coupling means 15, 25.
  • said coupling means comprise:
  • Figs. 3a and 3b which respectively show a perspective top view of the first frame 10 (and of the first strap 13) and a perspective bottom view of the second frame 20 (and of the second strap 23), it is possible to observe more clearly said at least one protuberance 15 and said at least one recess 25.
  • Figs. 2b , 3a and 3b show that said at least one protuberance 15 is associated with a free end 13E of the first strap 13 and said at least one recess 25 is associated with a free end 23E of the second strap 23.
  • said at least one protuberance 15 is obtained on a top face 13 S of the first strap 13, in particular near said free end 13E of the first strap 13; in a complementary manner, said at least one recess 25 is obtained on a bottom face 23I of said second strap 23, in particular near said free end 23E of the second strap 23.
  • first 13 and second 23 straps may comprise a plurality of protuberances 15 and/or recesses 25; moreover, each one of said first 13 and second 23 straps may comprise one or more protuberances 15 and/or one or more recesses 25.
  • said first 13 and second 23 straps comprise abutment means 16, 26 that ensure the correct alignment between the first 10 and the second 20 frames when the filter 1 is in the closed condition (as shown in Fig. 2a ).
  • said abutment means comprise:
  • first 13 and second 23 straps may be made in one piece with said first 10 and second 20 frames, respectively, e.g. when moulding said first 10 and second 20 frames, which are usually made of plastic material; as an alternative, said first 13 and second 23 straps may be manufactured separately from the first 10 and second 20 frames and then associated therewith.
  • said first 13 and second 23 straps are positioned substantially perpendicular to said first 10 and second 20 frames.
  • the free ends 13E, 23E of said first 13 and second 23 straps are corrugated, so as to increase the area of mutual contact. Furthermore, each one of said straps 13, 23 has a plurality of slots 17, 27, in particular for the purpose of allowing an adequate flow of air from the drum 102 of the clothes dryer 100.
  • the filter 1 substantially has a V-shaped cross-section, i.e. it is so designed as to be widest at said second edges 12, 22 and/or at said straps 13, 23, said filter 1 then getting progressively narrower to a minimum value at said first edges 11 and 21.
  • first 10 and/or the second 20 frames preferably have side walls 18, 28 (which are visible in particular in Figs. 2b , 3a and 3b ) getting narrower in the proximity of said first edges 11, 21.
  • the straps 13, 23 are associated with said first 10 and second 20 frames at the ends opposite to the first edges 11, 21; it is however apparent that it is not necessary that said second edges 12, 22 correspond to the ends of said first 10 and second 20 frames which are opposite to the first edges 11, 21. As a consequence, it is clear that the straps 13, 23 may be associated with different points with respect to the ends of said first 10 and second 20 frames.
  • the filter 1 is positioned underneath the door 103 of the clothes dryer 100, so that it can be easily reached by a user after opening said door 103; preferably, said filter 1 is housed in a duct C for recirculating air inside the clothes dryer 100.
  • a filter 1 for eliminating impurities present in the air jet of a clothes dryer 100 and of a clothes dryer 100 equipped therewith according to the present invention are apparent from the above description.
  • one of such advantages is that the peculiar design of the filter 1 according to the present invention facilitates the extraction of the filter 1 from the respective housing in the clothes dryer 100.
  • such a design facilitates the tasks of removing the impurities collected inside the filter 1 and of opening the filter 1 itself.
  • the holes 14, 24 of the straps 13, 23 allow the user to easily extract the filter 1 from the clothes dryer 100 as well as to easily disengage the coupling means 15, 25 to open the filter 1 by simply moving apart the holes 14,24.
  • the filter for eliminating impurities present in the air jet of a clothes dryer and the clothes dryer equipped therewith described herein by way of example may be subject to many possible variations without departing from the novelty spirit of the inventive idea; it is also clear that in the practical implementation of the invention the illustrated details may have different shapes or be replaced with other technically equivalent elements.
  • the present invention is not limited to the above-described filter for eliminating impurities present in the air jet of a clothes dryer and the clothes dryer equipped therewith, but may be subject to many modifications, improvements or replacements of equivalent parts and elements without departing from the inventive idea, as clearly specified in the following claims.
