Definitions

  • This invention refers to a kind of clothes drying machine, preferably of the type for use in households, which is provided with improved means for circulating the drying air to ensure high energy efficiency.
  • the present invention therefore applies also to the so-called exhaust-type clothes drying machines, in which the air is taken from the outside ambient, duly heated up, blown into the rotating drum, removed from the same rotating drum and, eventually, exhausted again into the outside ambient, as opposed to what occurs in condenser-type clothes drying machines, in which the air is on the contrary caused to circulate in a closed-loop circuit that includes a suitable condenser arrangement, so as this is illustrated symbolically in Figure 1 .
  • Both condenser-type and exhaust-type clothes drying machines share - further to the rotating drum - a common operating feature, i.e. the circumstance that in both cases there are provided an air delivery or inflow conduit and an outflow conduit, along with related openings arranged in the walls of the drum, through and in which the drying air is caused to circulate with the aid of means largely known as such in the art.
  • EP 1559827 discloses a basket for a laundry dryer machine or washer dryer of the type comprising a basket or drum suitable to house the laundry and provided with an Inlet aperture for a drying airflow, a system of ducts with associated ventilator means suitable to convey said airflow, through said Inlet aperture Into said basket, heating means arranged In the airflow upstream from the Inlet aperture and suitable to heat the air before it enters the basket.
  • the basket comprises deflector means suitable to deviate In a permanent way at least a portion of the airflow against a side wall of the basket, wherein said side wall is suitable to reflect the portion of the airflow towards the inside of the basket.
  • DE 196 16 634 discloses clothes dryer, as an electrical domestic appliance, has a circular drying air feed In the rear wall of the drum.
  • the container insert, placed In the interior of the drum, is cylindrical to match the circular drying air feed.
  • the drying air feed is divided into two sections to deliver the air to the centre and to the outer peripheral ribs within the drum, to pass through perforations In the ribs Into the drum.
  • a laundry drier has a drum which contains the laundry and which can be driven In rotation about an axis.
  • a current of air passes through a space inside the drum.
  • the current of air enters the drum through at least a first opening.
  • One or more drivers are arranged inside the drum. In order to obtain a laundry drier of shallow depth, the air current passes from the first opening into the driver(s) and then through openings In the driver(s) Into the space inside the drum.
  • US 2 670 549 discloses a dryer comprising an one air-impelling means adapted to draw air from the exterior of the drum, while other air-impelling means is adapted to draw air from some other source such as interior of the drying chamber, the two quantities of air are mixed in the outer portion of the air chamber and the mixture is then forced into the drum for drying the laundry therein.
  • a drum 1 adapted to hold the clothes to be dried, to which there is associated a delivery conduit 2 letting the drying air into the drum through an appropriate inflow opening 3, an air outlet or exhaust conduit 4 removing the drying air from the interior of the drum through a corresponding outflow opening 5, wherein said conduits 2 and 4 are joined to each other via a condenser 6, which is adapted to cause the moisture contained in the drying air flowing therethrough to condense, said condenser being furthermore flown through by a flow of "cold" air, i.e. air taken in from the outside ambient and sent to said condenser 6 via a corresponding cooling conduit 16.
  • "cold" air i.e. air taken in from the outside ambient and sent to said condenser 6 via a corresponding cooling conduit 16.
  • the preferred embodiment of the drying machine is provided with the following features:
