Definitions

  • This invention refers to a clothes drying machine of the type with a rotary drum, containing the material to be dried, which is traversed by a flow of hot air.
  • a machine of this type is usually composed of a bearing structure to which are secured the various functional elements of the machine such as air circulating fans, moisture condensers, heaters, etc. These functional elements are interconnected by suitable ducts which, together with the latter, constitute the air circulating and dehumidifying circuits.
  • the plurality of elements and connections required to achieve said circuits entails a considerable amount of assembling, resulting in relatively long operating times, a large number of operations to be carried out and a possible source of error by the personnel in charge of the assembling.
  • the known manufacturing methods are expensive and not wholly efficient.
  • the various connections between them are liable to be shaken loose by the vibrations of the machine, resulting in breakdowns and the need to carry out repairs.
  • the general scope of this invention is to obviate the aforementioned problems by providing a manufacturing method and a rotary-drum drying machine according to said method with a low number of connections and separate parts in the air circulating, heating and dehumidifying circuits.
  • a method, according to the invention for manufacturing a drying machine of the type having a rotary drum for containing the material to be dried, in particular clothes, traversed by dehumidified hot air, characterized by the fact of comprising the moulding of a base for said machine having, integrally formed therein, at least one box-shaped housing to receive a steam condenser, a housing for a pump for discharging the condensate forming in said box-shaped housing of the condenser, housings constituting scrolls of air circulating fans, housings for electric air heaters, housings for at least one motor to operate said fans and to rotate the drum, said method also comprising the moulding of ducts integral with said base for interconnecting the aforementioned housings to form at least part of circuits for generating and circulating said hot air and for circulating air for cooling and condensing the moisture from said hot air.
  • a drying machine is also provided of the type having a rotary drum which holds the material to be dried, in particular, clothes, and which is traversed by dehumidified hot air, characterized by the fact of comprising a base for said machine having, integrally formed therein, at least one box-shaped housing to receive a steam condenser, a housing for a pump for discharging the condensate forming in said box-shaped housing of the condenser, housings constituting scrolls of air circulating fans, housings for electric air heaters, housings for at least one motor to operate said fans and to rotate the drum, ducts integrally moulded with said base being also provided for interconnecting the aforementioned housings to form at least part of circuits for generating and circulating said hot air comprising the heater and the steam condensing path of said condenser, and at least part of circuits for circulating air for cooling and condensing the moisture from said hot air comprising an intake for collecting cold air from the outside and
  • a drying machine made according to the innovatory principles claimed herein and generically indicated by reference 10 in figure 1, comprises a base 11 on which are obtained by moulding in one piece (as can also be clearly seen in figure 2) a box-shaped housing 12 for an air-type steam condenser 13 of known technique, a housing 14 for a suction pump 15 for liquids, a housing 39 for connecting an electrical resistance heating unit 16, scrolls 17 and 18 for air circulating fans, driven by a motor 19 secured to said base and having a pulley 25 keyed onto its shaft which controls the rotation of a drum 22, containing the clothes to be dried, by means of a circumferential belt 20 tightened by means of a tightening pulley 21.
  • the drum is provided at both ends with air conveying shells 23 and 24 the first of which is connected from below to the heating unit 16 and the second, for example semitoroidal in shape to enable the material to be dried to be introduced into the drum, is connected from below to the suction inlet of the scroll 17.
  • the drum 22 has been drawn in figure 1 (likewise to the casing 26 of the machine) in transparency.
  • the scrolls 17 and 18 are advantageously made in one piece composed of two half shells connected by means of pliable seams 27 and 28 respectively.
  • the scrolls can be closed by simply turning over the upper half shells along the two seams 27 and 28 respectively.
  • the half shells are locked in place for example by means of clips which snap onto the contacting edges. Since these clips can be of any known type they are neither shown nor further described.
  • the half shells can alternatively be joined together by glueing or by means of screw fasteners.
  • the steam condenser supports baffles 31 and 32 and a closing wall 33 so as to form, when inserted in the box-shaped casing 12, air circulating circuits.
  • the first whose path is indicated by the letter "a" conveys air, which is made to move by the rotation of the fan composed of the scroll 17 and the blades 29, through the condensation path inside the steam condenser 13, then through the heater 16 and then on, through the shell 23, to the suitably perforated drum 22, passing through it and then returning, through the shell 24, to the fan 17, 29 and then recommencing the cycle.
  • the second air circulating circuit which is indicated in figure 3 by the letter "b" conveys air, sucked in from the outside through the inlet 34 of the fan composed of the scroll 18 and the blades 30, through the cooling path of the condenser 13, said path being disposed at right angles with respect to its condensation path forming part of the circulating circuit "a".
  • the air of the "b" circuit is discharged into the environment through an aperture 35 and slits 36 in the base.
  • the drum 22, drawn by the belt 20, begins to rotate and the two fans 18, 30 and 17, 29 generate said forced air circulations, so that the air heated by the unit 16 passes through the drum removing the moisture contained in the material to be dried and then passes through the condenser 13, cooled by the air from the inlet 34, so as to condense the moisture which drops onto the suitably sloped bottom 37 of the casing 12 and is then conveyed into the collection tank 14 housing the pump 15 which discharges it through a duct 38 to the outside of the machine.
  • the blades 29 and 30 are advantageously shaped together with their respective scrolls so as to constitute reversible fans so that the flow of air generated always moves in the same direction regardless of the direction of rotation of the blades.
  • the motor 19 can be alternately made to rotate for a certain length of time in one direction and for a certain length of time in the other direction, thereby preventing the clothes being dried from becoming tangled and at the same time improving the efficiency of the drying action, as will be clearly evident to any technician expert in the field.
  • the drying machine made according to the invention obviously comprises all the other devices of known technique necessary to operate a machine of this type.
  • it will be provided with thermostats, programmers, water level sensors in the tank 14 operating the pump 15, suspension means for the rotary drum, doors giving access to the latter, etc.
  • baffles 31 and 32 supported by the condenser can if required be moulded in one piece with the inside of the casing 12.
  • the drive system between the motor and the drum can be made according to other known techniques; for example with friction rollers mechanically connected to the motor and disposed in contact with the outer circumferential wall of the drum.
  • Rollers can also be provided, with bearings moulded directly into the base 11 to partially or fully support the drum.
  • the disposition and shape of the various elements moulded in the base is not restrictive. Depending upon the available dimensions of the various elements and those desired for the complete machine, they can be made with other dispositions and shapes as will be undoubtedly clear to the technician.
  • the housing for the heating unit 16 can be made in the form of a box-shaped casing into which the unit can be inserted, in the same way as the housing for the condenser 13.
  • the base including the various parts of the machine can be advantageously made by means of the technique known as blow moulding and subsequently machined to obtain the various slots.
