Definitions

  • the invention relates to a method for washing and drying linen and its application device.
  • washing-drying machines already exist, with which the washing operations are carried out according to the conventional method of introducing water, with or without the addition of detergents, into a tank, inside which a drum , the periphery of which comprises multiple perforations, is driven in rotation, and the drying operations are carried out by introducing hot air inside the tank, with the latter escaping via a diametrically opposite duct, with respect to to the drum, to that of admission; this air can be recycled, after drying and possible reheating; the drum being rotated during this time.
  • a washer-dryer machine comprising a device aimed at promoting the introduction of air inside the drum, in the vicinity of its axis of rotation, so that it can pass through the laundry from the inside. outward from the drum. It is a front-loading machine, the tank of which comprises, in the vicinity or in the loading hatch, a nozzle, supplied by a duct arranged in the front face of the machine. This considerably improves the air-linen exchange and, consequently, performance, provided that the relevant face of the drum is provided with adequate perforations and that the air jet is correctly directed.
  • the method and the device according to the invention aim to remedy the drawbacks mentioned above.
  • This invention as it is characterized, therefore solves the problem of defining a method and producing a device with which the washing liquid and the drying air are introduced in whole, or in large part, at the level of the axis of rotation of the drum and emerge through the perforations existing at the periphery of the drum, after having been in direct contact with the laundry; this without the traditional architecture of the machine being fundamentally questioned.
  • the washing or rinsing water and the drying air circulate from the axis of the drum towards the periphery of the latter.
  • the washing or rinsing water circulates from the axis of the drum towards the periphery thereof, while the drying air circulates in the opposite direction.
  • the device for applying the method according to the invention is mainly characterized in that the circulation of the washing or rinsing water and the drying air takes place through the shaft of the drum; in that the detergents and softeners are introduced into the water stream, upstream of the drum; in that the washing or rinsing liquid is heated by circulation in a closed circuit, through a battery of heating elements; in that the drying time is determined, by the programmer of the machine, as a function of the humidity of the air escaping from the drum, and in that the cleaning of the drying circuit is carried out via a water injector, mounted in the air line, upstream of the fan and in the vicinity of the axis of rotation of the turbine thereof.
  • the washing or rinsing water is introduced into the hollow shaft of the drum via a nozzle, connected to the suction strainer located in the sump of the tank, via a conduit serving a pump, heating elements, a temperature probe and a nozzle for dosing and introducing detergents.
  • the hollow shaft of the drum is placed in external communication with the tank, via a pot, surrounding the water introduction nozzle, and a pipe serving a hygrometric probe, a water injector, a blower, a condenser, heating elements and a thermometric probe.
  • the shaft of the drum can be extended to the opposite wall of said drum by a tube having multiple perforations.
  • the shaft of the drum comprises, at its outlet, towards the inside of the drum, a perforated apple.
  • the inlet has a flange surrounding the water introduction nozzle.
  • the advantages obtained consist essentially in that it makes it possible to rationalize the quantities of water, detergent, softener and energy, with optimization of the heating temperature and the time necessary for the obtaining the desired degree of drying, depending on whether one wishes to have clothes that can be stored or ironed, while allowing a total self-adaptation of the process to the load of laundry.
  • the figures represent a washing and drying machine according to the invention, one of the sides 11 of the drum 10, connected to the tank 20 by means of a hollow shaft 21 opening outwards, in a pot 31 connected to the tank by a pipe 30, serving a hygrometric probe 32, a water injector 33, a blower 34, a condenser 35, a block of heating elements 36 and a thermometric probe 37, and, towards the interior of the drum 10, by means of a tube 12, having multiple radial perforations 121, or of an apple 13 with perforations 131, the inlet orifice of which comprises a flange 122 or 132, surrounding the nozzle of a nozzle 41 for introducing water passing through the pot 31 ; said nozzle 41 being connected to the suction strainer 241, located in the sump 24 of the tank 20, by a conduit 40 serving a pump 42, a battery of heating elements 43, a thermometric probe 44 and a nozzle 45 d introduction of detergents.
  • the equipment 32 - 37, located on line 30, and 42 - 45, located on line 40 are controlled by a programmer, well known from those skilled in the art, it is possible to automatically apply, during the washing and drying process, the process according to the invention in its entirety, that is to say to circulate the washing and rinsing fluids and drying through the drum, starting from the axis to go towards the periphery thereof, introducing the softener during the last rinse, carrying out the latter rinse at a perfectly controlled temperature, ensuring spinning at a specified speed and for a specified period of time and drying for a specified time and temperature depending on the nature of the textile fibers and the degree of drying desired (clothes that can be stored or ironed) ).
  • This operation may be required before drying, in order to reduce the duration, which will be all the more reduced as the hot air is mixed, more intimately and in its totality, with the laundry to be dried, which is, during this time, subject to mechanical effects due to the alternating rotation of the drum.
  • textile flock can stick to the blades of the blower turbine.
  • a cleaning of these blades can be carried out by an injection of water into the suction stream, that is to say upstream of the fan, in the vicinity of the axis of rotation of the turbine of the latter. this.
  • the device for applying the particular definition of the process consisting in circulating the drying air radially, from the periphery of the drum towards the axis thereof, while the circulation of water is maintained in the direction on the contrary, it is easily deduced from that described above by simple reversal of the order of assembly of the equipment 32 to 37 on the pipe 30 connecting the pot 31 to the tank 20, unlike that indicated in FIG. 3.
  • the method and the device according to the invention are intended, mainly, to equip household washer-dryers, but there is nothing to prevent them from being used on professional or even industrial machines, subject to minor adaptations .
