Definitions

  • the present invention relates to a device for drying textile objects with the features of the preamble of claim 1 and a method for drying textile objects with the features of the preamble of claim 15.
  • Generic devices for drying textile objects have at least one support arm, the at least one support arm being designed to hold a textile object—preferably a towel. This can be done by placing the textile object over the support arm, hanging it or attaching it to it with clothespins, for example.
  • These support arms can be used, for example, in towel rails in the bathroom, in clothes stands, foldable clothes stands, laundry spindles or the like.
  • the drying can be accelerated by the increased air flow, which is directed to the textile object to be dried, since a larger air volume per time is provided, which can absorb the moisture of the textile article by evaporation.
  • Such a device is described for example by DE 10 2012 102 129 B3.
  • a disadvantage of known devices and methods of the prior art is that "hair dryer"-like devices are used to generate a heated air flow, which have a combination of a fan and a heating device. These devices have a short service life, since they often break after a few minutes to hours of continuous use due to the heating. With regard to the relatively long drying times of textile objects, this is to be seen as a major disadvantage.
  • a further disadvantage lies in the fact that devices of the prior art can only be used with the use of a fan or a similar flow device, as a result of which a certain sound level is permanently generated by the device, which can be regarded as annoying due to its monotonous tone.
  • the present invention is based on the object of providing a device for drying textile objects and a method for drying textile objects, wherein more energy-efficient and/or faster and/or more user-friendly drying of textile objects is made possible compared to the known prior art.
  • This object is achieved by a device for drying textile objects with the features of claim 1 and with a method for drying textile objects with the features of claim 15.
  • an electrical resistance heater is arranged in the cavity of the at least one support arm, which preferably does not overheat even without an air flow.
  • the gaseous fluid flowing through - preferably air - and/or the carrier arm itself can be heated for drying by means of a resistance heater arranged in the cavity, the heated gaseous fluid directed to the textile object and/or being released via the carrier arm to the textile object Thermal energy can accelerate the drying of the textile article.
  • the support arm itself can be heated via the electrical resistance heating, whereby the drying of the adjacent textile object, which is preferably designed as a towel, can be accelerated.
  • a gaseous fluid which flows through the cavity can also be heated by the electrical resistance heating arranged there, as a result of which the gaseous fluid flow which is passed on to the textile object can also be heated.
  • the gaseous fluid is additionally heated to further support the drying process
  • a device for drying textile objects according to the present invention is used to heat the environment, for example rooms.
  • Textile objects can be, for example, towels, sheets, blankets, clothing or the like.
  • the device for drying can preferably be designed as part of a drying rack, which can preferably be folded up or folded up against a wall.
  • the device for drying textile objects is used as a towel holder, for example in a bathroom, or is provided as part of a laundry spindle.
  • the support arm can be formed from tube material, which can be available as rod material.
  • the at least one carrier arm is designed with a variable cross section, which is preferably adapted in terms of fluid technology or flow technology with its cross-sectional shape along the longitudinal extension.
  • the at least one carrier arm can also be designed with a tapering cross section, so that a flow velocity or a pressure can be kept constant along a longitudinal extension (if several outlet openings are provided along the longitudinal extension).
  • the outlet openings are adapted to an attachment of a textile object.
  • the large number of lateral outlet openings can be directed downwards, so that the flow of gaseous fluid passing through the outlet openings is not restricted by a towel lying against it, but is guided into the free space below will.
  • the electrical resistance heating is arranged—preferably in a loop or meander shape—along a longitudinal axis of the support arm, and preferably extends over essentially the entire length of the support arm inside the same.
  • a distance between the electrical resistance heater and the at least one outlet opening can be, for example, less than 5 cm, preferably less than 2 cm, particularly preferably less than 1 cm. However, distances greater than 5 cm are also quite conceivable.
  • a strand consists of a large number of thin wires, and the entirety of these thin wires which are in contact with one another is called a strand referred to as. These wires are primarily made of copper or some other electrically conductive metal. Colloquially, such strands are often referred to as cables.
  • a device for generating a flow in the cavity can have a fan, a turbine and/or a pump, for example.
  • This device can be arranged inside or outside the carrier arm, for example it can also be formed by an external fan.
  • the device for generating a flow in the cavity can be designed, for example, as a central unit which preferably supplies several cavities or devices for drying a textile object.
  • the device for generating a flow in the cavity can be provided at a distance from the cavity, so that the background noise caused by the device for generating a flow in the cavity is not directly noticeable in the application area of the devices for drying a textile object.
