Definitions

  • the present invention relates to a device for the dis­charge of moist air from a laundry dryer of the domestic type having an open drying air circuit.
  • Appliances of this type comprise a laundry-receiving drum rotatably mounted in a housing for the passage therethrough of warm drying air which a ventilator aspirates from the environment to direct it through a heater apparatus and through the laundry-receiving drum, from which the then warm and moist air returns to the exterior of the appli­ance through a discharge conduit connected to the housing of the appliance.
  • the housing is usually provided with several discharge openings formed in different walls thereof, for instance in the sidewalls and the rear wall.
  • an extensible conduit is usually provided for connection to a selected discharge opening of the housing, the free end of the conduit being adapted to be connected to an outlet, for instance a window, a door, a ventilation shaft or the like of the room in which the appliance is installed.
  • This extensible conduit which may have a length of about 2.5 meters when fully extended, involves numerous disad­vantages, however, the most important one of which is the difficulty of suitably storing it when not in use.
  • the one end of the extensible conduit can be readily fixed to the selected outlet opening of the housing as by means of a hose clamp, a snap fit attachment or a bayonet coupling
  • the other end of the conduit is usually only clamped between the door, the window or the like and its respective frame. This does obviously not ensure a reliable retention of the free end of the conduit, which may therefore assume any pos­ition.
  • a laundry dryer known from German Patent 3,044,731 is provided with an extensible discharge conduit which is premanently connected to an air outlet and housed in a chamber formed in the housing of the appliance in the contracted inoperative state.
  • a lid for closing the chamber is hinged to the extensible conduit and provided with means for releasably securing the free end of the conduit to a window grille or the like.
  • European Patent 0,071,312 describes a laundry dryer with a discharge conduit in the form of an extens­ible hose which in its inoperative state is housed within the appliance and can be withdrawn therefrom to the required length for connecting it to a ventilation opening.
  • the extensible conduit is not an accessory of the appliance, but an integral part thereof. This results in a considerable limitation of the flexibility regarding the installation of the appliance, since the air discharge opening has always to be provided on the side of the housing formed with the access opening to the chamber housing the conduit.
  • the main object of the invention is the provision of a device for the dis­charge of air from a laundry dryer of the type described, permitting the extensible conduit to be readily detached from the appliance and to be conveniently stored when not in use.
  • a further object of the invention is to simplify and ration­alize the handling of the extensible conduit while retain­ing its character of an independent accessory of the appliance.
  • a device for the discharge of moist air from a laundry dryer particularly of the domestic type and having an open circuit for the discharge of the warm and moist drying air to the environment through one or several outlets formed in the housing of the appliance, and a resiliently extensible conduit which in the operative state is releasably connectable to one of the discharge outlets of the appliance and to a ventilation opening in a boundary wall of a room in which the appliance is installed, and which in its contracted inoperative state can be accommodated within the appliance
  • said device comprises a receptacle for the extens­ible conduit in the form of a rigid tubular sleeve, and two coupling rings secured to the ends of the conduit and provided on their outer surfaces with respective first and second quick-coupling means, said first quick-coupling means being adapted to connect the respective ends of the conduit to the ends of said receptacle, and said second quick-coupling means being adapted to connect one end of the conduit to a discharge outlet of the
  • Shown in fig. 1 is a conventional laundry dryer 5 of the open drying-air circulation type, comprising a housing 6 in which there is rotatably mounted a drum 7 for contain­ing the laundry to be dried.
  • dryer 5 also includes a fan operable to aspirate air from the environment and to direct it through a likewise not shown heater device and through drum 7 for subsequent discharge through at least one of several discharge outlets 9, 10, 11, 12 formed in different walls of housing 6 of dryer 5.
  • Discharge outlets 9, 10, 11, 12 are adapted to have a conduit connected thereto for directing the moist air discharged from the dryer to the ambient exterior.
  • this conduit 13 is extensible and adapted to be coaxially housed in a cylindrical receptacle 14 adapted to contain the full length of conduit 13 in its contracted inoperative state.
  • the ends of extensible conduit 13, which may for instance be made of a helically wound metal wire and a plastic envelope bonded thereto, are releasably secured in respective double-sided coupling rings 15, 16 (fig. 2), for instance by being threadedly engaged with helically grooved walls of openings extending through rings 15 and 16.
  • Each coupling ring 15, 16 carries on its outer peripheral surface two groups of coupling pins 17 and 18 adapted respectively to permit the ends of conduit 13 connected to respective ends of receptacle 14, and coupling ring 16 to be connected to a discharge outlet of the appliance, and coupling ring 15, to a ventilation passage (not shown) or the like.
  • coupling ring 15 may be coupled to a diffuser element 20 having an elongate flattened dis­charge outlet 21 and a flexible hook member 22 permitting diffuser element 20 to be releasably secured to a window sill , a shutter or the like.
  • the geometry and the flexibility of hook member 22 are of course selected so as to permit it to be engaged with window sills 25, shutters or the like of different thickness (Fig. 5).
  • Discharge outlet 21 of diffuser element 20 is surrounded by an outwards projecting rim 23 permitting diffuser 20 to be retained by a sash window or a sliding shutter.
  • Receptacle 14 may also be permanently installed in the wall of a room or the like to act as a ventilation passage and at the same time as a housing for storing extensible conduit 13 when not in use.
  • the outer surface of receptacle 14 is provided with longitudinally extending ribs 24 for facilitating the handling of the device or for anchoring the receptacle when it is permanently installed in a wall or the like.
  • receptacle 14 may be made of an extruded plastic material and cut to a suitable length as required by the dimensions of extensible conduit 13 and/or the wall in which it is to be installed.
  • the invention attains the stated object of providing a discharge device permitt­ing the extensible conduit to be conveniently stored in its contracted state when not in use, while retaining its character as a separate accessorie of the appliance.
  • connection means on coupling rings 15, 16, receptacle 14, diffuser element 20 and the discharge outlets of dryer 5 may thus be formed as snap-fit connector means, screw-threaded connections or any other type of readily and quickly releasable connection.
