Definitions

  • the present invention relates to a top opening dryer.
  • Solutions aimed at creating a mixing of the laundry in a horizontal drum during drying are known. Some provide spaced transverse ribs, parallel to the axis of rotation of this drum, on the inner surface of the shell of the horizontal laundry drum. The others use a formation on the inner surface of the shell of this horizontal drum of spaced transverse ribs, oblique with respect to the axis of rotation of this drum.
  • the transverse ribs parallel to the axis of the drum make it possible, during a rotatlon of the latter, to pull pieces of the laundry which are in a low part in this drum, towards a high part, to drop them and to start again the same operations until drying stops.
  • oblique transverse ribs with respect to the axis of the drum constitute for the laundry, during a rotation of this drum, sliding ramps which bring it back from one end to the other end of this drum and create rather a compaction of the laundry items at one end of this drum than a uniform mixing of this laundry.
  • Another known solution aims to overcome the bad effect of packing the laundry at one end of the drum, mentioned in a previous paragraph, by using this end of the drum as the end of the drying air inlet in order to force this drying air to go against this pile of linen, and in addition giving the flange of the opposite end of this drum, a shape substantially of a truncated cone in order to converge at this end, the drying air towards the axial zone of this drum where there are pieces of laundry which are about to be forced back by the oblique transverse ribs.
  • the present invention aimed at avoiding these drawbacks, makes it possible to produce an economic, efficient dryer, effecting a good stirring of the linen and giving a dried linen with a minimum degree of crumpling.
  • a dryer with top opening and horizontal laundry drum is characterized in that the laundry drum comprises two flanges which simultaneously, during drying of a laundry, perform several functions, namely that of apliers or supports for the rotation of the shell of this drum, that of passages for drying air, that of means for guiding and correcting the movement of the linen in this drum, that of means for smoothing the linen , that of protective covers for heating and ventilation devices.
  • a dryer 1 is a dryer with top opening.
  • the dryer 1 comprises a body 2, having in the top, an opening 3 closed by a door 4, and a laundry drum 5 having a horizontal axis and provided in its cylindrical side wall, with an access door 10 In its high position, the access door 10 is in alignment with the opening 3 and the door 4, which facilitates the loading and / or unloading of the drum 5 in linen.
  • the laundry drum comprises two flanges which during drying of a laundry simultaneously fulfill several functions, namely that of bearings or supports for the rotation of the shell of this drum , that of passages for drying air, that of means for guiding and correcting the movement of the linen in the drum, that of means for smoothing the linen, that protective covers for heating and ventilation devices.
  • the horizontal laundry drum 5 of the top-opening dryer 1 comprises on the one hand a movable cylindrical shell 8 mounted to rotate freely along a horizontal axis 6 and provided on its internal surface with at least a transverse rib 12 parallel to this horizontal axis 6, and on the other hand two fixed flanges 14 and 15 which support in rotation the two ends of this movable ferrule 8.
  • the fixed flanges 14 and 15 respectively comprise cylindrical bearing surfaces 17 and 18 projecting on their internal surfaces and which serve bearings or sliding ring supports for the rotation of the movable shell 8.
  • the fixed flat flanges 14 and convex 15 are provided in their surfaces with perforations or holes 20,21 serving as passages for entry and exit drying air.
  • the curved fixed flange 15 is provided on its inner surface with a coaxial filter with a flock of linen 23 and a coaxial protective grid 24 which contribute to reinforcing the curved shape of this flange.
  • the flat fixed flange 14, the domed fixed flange 15 and the movable cylindrical shell 8 which define an internal volume of the drum 5, asymmetrical with respect to a transverse median plane 26, constitute in their combination during a rotation of the movable ferrule 8, complementary active surfaces which communicate to the linen a complex movement realling a careful and uniform wise arm of the linen.
  • the transverse rib or ribs 12 drive (s) the laundry items from bottom to top, in substantially vertical planes up to a certain height in this drum where these laundry items by their weight slide and fall back down.
  • some parts or parts of these moving laundry items which evolve in the proximity of the fixed flanges 14,15 are variously braked in their ascent or fall by their contact with these immobile flanges and axially repelled more or less by these flanges depending on whether the shape of the latter is curved or flat.
  • an electric heating device 28 is mounted in the space between the body 2 and the laundry drum 5, near the flat fixed flange 14 and deployed regularly along the surface of the latter for both heating the drying air, indicated by arrows 30, 31, before entering the laundry drum 5, and bringing the surface of this fixed flange 14 to a preset uniform temperature which produces an ironing or smoothing effect on the pieces of laundry rubbing against this surface.
  • the fixed fixed flange 14 forms, with the wall 37 of the adjacent body 2 and the heating device 28, an inlet and heating sheath 38 for the drying air.
  • the fixed flat flange 14 thus constitutes both an effective means of smoothing the linen and a protective envelope for this electric heating device 28.
  • a reflector 29 is mounted between the body 2 and the heating device 28 to minimize heat losses by conduction through the body 2.
  • a ventilation device 32 is mounted in the space between the body 2 and the drum 5, near the domed fixed flange 15, coaxially with this flange to create by suction, a current of drying air 34.35 through the laundry drum 5.
  • the domed fixed flange 15 forms with a counterflange 39 and the ventilation device 32, a drying air outlet duct 40 and a protective casing for this ventilation device 32.
  • the movable ferrule 8 and the ventilation device 32 are respectively driven through transmission belts 41 and 36 by an electric motor 33.
  • the horizontal laundry drum rotating around a horizontal axis is generally a cylindrical container whose ferrule and end flanges are normally assembled and fixed by welding or crimping.
  • This usual structure of the laundry drum is simple and easy to make.
  • the dryer 1 with opening from above described in the preceding paragraphs achieves, on the other hand, excellent performances in comparison with those of the dryers known of the same type. These good performances are reflected in the dryer 1 by a great reduction in the drying time and in the energy consumption, necessary to obtain a selected degree of drying of the linen and by a surprising result of smoothing the dried linen. .
