Definitions

  • the present invention relates to a condensation laundry dryer, particularly of the front-loading type for domestic use, in which the relative position of a condensate collecting receptacle and an air-cooled condenser apparatus, both of which are removable mounted in the interior of the machine, have been advantageously modified with respect to the known arrangement.
  • the heated air after having passed through the drum containing the laundry is dehumidified in a condenser cooled by ambient air which is removably mounted in the machine so as to facilitate its periodic inspection and cleaning by user.
  • the obtained condensate is collected in a receptacle like­wise removably mounted in the machine for permitting it to be emptied as required by the user.
  • laundry dryers which to the purpose of facilitating the various operations during use are provided with a condensate collecting receptacle mounted at an upper portion of the machine as described for instance in German Patent Application 32 04 396.
  • Italian Utility Model No. 195,977 offers a more rational utilization of the internal space of a condenser laundry dryer by the employ of a closure door or window additionally acting as a receptacle for collecting the condensate.
  • the present invention has for its object to combine the advantages of this particular construction of the condensate collecting recptacle with an arrangement of the condenser permitting the complicated and expensive liquid collecting devices such as pumps and conduits of known solutions to be eliminated to thereby facilitate the operation and main­tenance of the laundry dryer.
  • a condenser laundry dryer particularly of the front-loading type for domestic use, comprising a closed circuit for the circulation of heated drying air through at least one heater element, a drum containing the laundry, and a removable mounted condenser apparatus con­nected to a condensate collecting receptacle likewise removably supported in the closure window of the machine and an open air circuit for cooling the condenser apparatus, wherein said condenser apparatus is accommodated in an upper portion of teh machine at a higher level than said condensate collecting receptacle and is connected to said receptacle by means of a conduit and per se known valve means.
  • a condenser laundry dryer comprises an outer housing 5 with a drum 6 for containing the laundry mounted therein for rotation about a horizontal axis.
  • Housing 5 has a front opening 7 in alignment with the loading opening 8 of drum 6 and adapted to be closed by a closure door or window 9 as described in applicant's Italian Utility Model No. 195,977.
  • Drum 6 is adapted to be rotated by a motor 10 mounted in the top portion of the machine with the interposition of a friction roller 11 made of a resilient high-fraction material such as rubber.
  • friction roller 11 may be replaced by a gear adapted to cooperate with a corresponding annular rack on the cylindrical peripheral wall of drum 6.
  • drum 6 may also be rotated with the aid of a conventional belt transmission.
  • Friciton roller 11 itself is rotated about its shaft 12 secured to a shield 13 of motor 10 by a drive wheel 14 secured to the motor shaft 15.
  • the drying apparatus proper of the machine comprises a blower 16 (fig. 2) for the forced circulation of drying air in a closed circuit including an outlet passage 17 housing electric elements 18 for heating the air, drum 6 containing the moist laundry, an internal portion of window 9 provided with a fluff filter 19, a riser conduit 20 and finally the ambient-air cooled condenser 21.
  • a blower 16 for the forced circulation of drying air in a closed circuit including an outlet passage 17 housing electric elements 18 for heating the air, drum 6 containing the moist laundry, an internal portion of window 9 provided with a fluff filter 19, a riser conduit 20 and finally the ambient-air cooled condenser 21.
  • drum 6 of the machine is provided with a perforate rear wall 22 in the known manner.
  • the open circuit for cooling condenser 21 comprises a blower 23 for aspirating ambient air through an opening 24 and directing it through condenser 21 to finally expel it from the machine through another opening 25.
  • condenser 21 is positioned in an upper portion of the machine above drum 6 so as to permit the condensate, i.e. water produced by condenser 21 to flow by gravity into a collector receptacle 26 in window 9.
  • a bottom wall 27 of a housing of condenser 21 is formed so as to direct the condensed water into a conduit 28 communicating with collector receptacle 26 in window 9 through known valve means already described in the above mentioned utility model no 195,977.
  • This arrangement is conducive to facilitating maintenace and repair operations and permits the elimination of a bottom plate in housing 5 formerly used for mounting the functional components which in the machine according to the invention are mounted in the top portion thereof.
  • This arrangement offers the additional advantage of permit­ting the provision of a lower adjustable ballast weight with particular advantage in the case of a combination-type laundry dryer.
  • the main characteristic of mounting the condensing apparatus at a level above that of the condensate collecting recept­acle at positons readily accessible for the user is of course also advantagous in the case of a laundry drying machine in which the remaining functional components are disposed at other locations. Any such arrangement permits a pump and conduit for lifting the condensate to a collect­ion receptacle in the upper part of the machine to be omitted.
  • both the condenser and the condensate collection receptacle are mounted at positions conducive to facil­itating the operation of the drying machine by its user.
  • the elevated pos­ition of the condenser is particularly advantageous with a view to discharging the condensate at an external dis­charge location such as a sink or wall drain.
