Definitions

  • the present invention relates to a machine and a method for wet cleaning, drying and smoothing of textiles, in particular laundry and clothing articles.
  • a housing preferably a predominantly circular housing with an inner barrel, in which a plurality of carriers for hanging the textiles can be fastened, the barrel being driven by an electric motor to produce a lateral Rotatonic movement of the textiles.
  • German published patent application DE 100 34658 A1 discloses a machine and a method in which the textiles are spread out in a drum, fastened and cleaned in this state.
  • a high cleaning effect is achieved by repeatedly increasing the speed of the inner drum during the alternating wash and rinse cycles and then greatly reducing it.
  • the drying process is carried out by the feeder of hot air into the drum interior. Due to the fastening method of the textiles, their smoothing is only moderately possible during the drying process and the cleaning process is also unsatisfactory due to the close-lying layers of fabric.
  • German OS DE 101 28775 A1 proposes a method for smoothing clothes, in which a perforated steaming dummy is arranged as a clothes holder in a rotatable drum, into which air can be introduced through a hollow axis of the drum mounting.
  • the disadvantage here is that only one item of clothing can be treated per washing, drying and smoothing process.
  • the construction of the machine belonging to the method is complex and the connection between the fixed air supply and the rapidly rotating drum axis is highly susceptible to wear.
  • the invention has for its object to improve a machine of the type mentioned in such a way that several items of clothing are cleaned, dried and smoothed simultaneously within a short time, the cleaning is more thorough and the smoothing is more complete, and that a reduction of the Energy consumption is achieved.
  • the machine according to the invention for wet cleaning, smoothing and drying textiles, in particular laundry and clothing articles has in a preferred embodiment, a circular housing with an inner drum, in which several carriers for hanging textiles can be attached.
  • the vertical axis of rotation of the running drum is fixedly connected concentrically to the motor shaft of an electric motor. Rotation of the motor shaft thus produces a lateral rotational movement of the textiles hanging inside the running drum.
  • the textiles can be hung on the clothes drum on a clothes rack, while they are spread out, cleaned, dried and smoothed.
  • the machine for wet cleaning and for smoothing clothes and laundry items in which they are spread out in a drum on the drum shell, fastened, washed, spun and dried by introducing air into the machine, on the outer shell comprising the drum an extension (22) in the tangential direction, or in a tangential direction parallel direction, which has a vent connection and at least one drain connection in the lower region, the rotation of the running drum being directed towards the tangential extension.
  • the housing comprising the inner running drum has, in its bottom region, an outward extension in the form of an attachment, which has at least one connection for air, in particular for ventilation, and at least one drain connection.
  • the extension of the housing is oriented in the same tangential direction or flow direction in which the textiles and the drum are accelerated.
  • the invention results in an increase in air performance and prevents air droplets containing air from being drawn in by the running drum, since the air is pressed into the tangential extension and can escape upwards. Liquids collect within the extension from where they are can either run off or be vacuumed by a circulation pump and fed back into the washing process.
  • the advantage of such a water return is that the liquid collected is not mixed with air, which means that the circulating pump used is more efficient, more powerful and less noisy.
  • the cover part of the housing has a tube piece coaxial with the axis of rotation of the running drum, the lower opening of which is directed into a perforated central tube and the upper opening of which is connected to a fan for vertical supply of dry air. This ensures an optimal distribution of the dry air within the drum.
  • the lower end of the center tube is closed and coaxially non-positively connected to the motor shaft of the electric motor, as a result of which the running drum can be set into a rotational movement when the electric motor is in operation.
  • radial tubes emerge radially from the central tube, hereinafter referred to as radial tubes, through which the dry air can be distributed and fed to the items of clothing hanging on the clothes carriers.
  • the ends of the radial tubes have sleeves that can be sealingly attached to the clothes racks and that allow effective air introduction.
  • treatment media in particular detergents and fresh water
  • treatment media can be introduced into the perforated center tube, which emerge from the center tube due to the centrifugal force when the running drum rotates and are applied to the clothing from the outside, while some of the treatment agents are passed through the radial tubes, so that the Garments can also be treated with treatment agents from the inside.
  • the use of nozzles which always require cleaning for spraying such treatment media can thus be avoided, as a result of which the construction cost of the machine and its production costs can be kept low.
  • the clothes carriers are designed as clothes hangers for hanging textiles, which can be covered with an elastic, air-permeable fabric.
  • the clothes carriers also have means for directly absorbing the dry air guided over the radial tubes. This results in a particularly gentle and even drying of the garments, in which they are additionally smoothed.

It is advantageous here if the running drum rotates at a high speed, so that the centrifugal effect on the textiles, the water contained in them is driven out. The heat is transferred to the clothing by the heated air and by the heat radiation emitted by the heated central tube 3. The efficiency is significantly higher with this method than with comparable methods, in which heating registers located outside the machine are used.

  • the air emerges from the openings 2 at the same time, sweeps over the colder walls of the housing 9 and is sucked in again by the open top drum 1 due to the negative pressure arising in the running drum 1.
  • the moisture in the air condenses on the inside of the housing 9, the extension 22 of which absorbs the water.
  • the condensed water can then be removed using the pump 24.
  • This continuous air circulation removes more and more moisture from the dry air, which means that its moisture content decreases increasingly. A particularly gentle and due to the large-scale inner wall of the condenser drying is possible. It is also advantageous with this method that the heat of condensation given off by the heating rods can be used to heat the alkali for the next batch.

Abstract

L'invention concerne une machine et un procédé pour laver, sécher et lisser des textiles, notamment du linge et des articles d'habillement. Cette machine présente un boîtier principalement rond (9) comportant un tambour conique intérieur s'élargissant vers le bas, dans lequel peuvent être fixés plusieurs supports (19) servant à l'accrochage des articles textiles. Par l'intermédiaire de son axe de rotation vertical, ce tambour (1) est raccordé solidement de manière concentrique à l'arbre d'un moteur électrique (8), ce qui permet d'obtenir, lors du fonctionnement du moteur, un mouvement de rotation latéral des articles textiles. Le boîtier (2) présente, dans sa zone côté fond, une partie élargie (22) orientée vers l'extérieur, sous la forme d'une partie rapportée qui comporte au moins un raccordement (23) pour l'air, notamment pour une aération, et au moins un raccordement d'évacuation.
