Definitions

  • the present invention relates to a tumble dryer according to the preamble of claim 1 and to a method for drying laundry by means of such a tumble dryer according to claims 11 to 13.
  • a further disadvantage is that the heat generation takes place directly with electric current, which can lead to a high power consumption of such dryers with electric heating. This leads to an inefficient type of laundry drying, which today may be highly undesirable against the background of rising electricity costs and from the perspective of environmental impact.
  • heat pump tumble driers are known. These have a closed heat pump cycle with a compressor, an evaporator, a condenser and a capillary. Through this heat pump cycle the process air moisture is removed, which was previously removed from the laundry. For this purpose, the previously heated by the heat pump cycle and dehumidified process air is passed through a fan through an air supply duct in a laundry drum of the tumble dryer. In the laundry drum, the laundry to be dried is usually moved by rotation, so that the process air can reach the laundry as completely and uniformly as possible.
  • the heated process air absorbs moisture from the laundry and dries it.
  • the moist process air then returns via an air return channel to the heat pump cycle.
  • the moisture extracted from the laundry is condensed from the process air and discharged in liquid form to the outside.
  • the energy extracted from the process air is returned to the process air so that the process air, once heated, leaves the heat pump cycle in the direction of the laundry drum.
  • the cycle of process air is closed in this way.
  • Examples of heat pump tumble dryer provide the EP 2 642 018 A2 and the DE 42 12 700 A1 represents.
  • a heat pump tumble dryer is a condensation dryer that heats the process air by convection.
  • the process air heats the laundry by convection and evaporates the water.
  • the moist warm air is then dehumidified and cooled in the air condenser (heat pump evaporator). It must be ensured that in the designed heat pump cycle before entering the compressor overheating is ensured, i.
  • the compressor should only draw in dry steam and not a two-phase mixture as this would cause the compressor to fail.
  • condition of the refrigerant is heavily dependent on pressure and temperature. These two parameters and thus the entire heat transfer process are decisively influenced by the enthalpy flow of the process air and the onset of condensation on the heat transfer surface of the air condenser. This means that process management is necessary for the shortest possible drying time, which increases the enthalpy flow of the process air, adapts it to the operating range of the heat pump, ensures overheating and allows as much water as possible to condense out of the process air.
  • heat pump tumble dryers are significantly more energy efficient than tumble dryers with electrical resistance heating elements, they have a much lower temperature range, which can be achieved by means of the heat pump. This can lead to significantly longer drying times.
  • induction dryers are known. This type of heating uses the principle of the transformer.
  • Flat copper coils are usually provided, through which an alternating current with frequencies between 20 kHz and 100 kHz can flow.
  • the current flow creates a primary magnetic field around the tightly wound coil, which constantly changes direction in response to the changing sign of the current. If a ferromagnetic material is within the range of action of this magnetic field, the high-frequency primary alternating magnetic field passes through this material and induces surges and thus eddy currents. These enclose the magnetic field in a ring shape and in turn cause a secondary magnetic field.
  • the secondary magnetic field counteracts (flux displacement) the changes in the magnetic flux of the primary magnetic field, especially in the interior of the ferromagnetic material, such that the primary magnetic field can only penetrate into the surface of the ferromagnetic material.
  • the eddy currents induced by the primary magnetic field do not uniformly pass through the ferromagnetic material, but merely flow in a thin boundary layer.
  • the property of high-frequency eddy currents to flow only in the "skin" of a conductor means that the effectively used line cross-section is reduced. This increases the resistance of the conductor so that the eddy currents in the surface layer generate enough Joule heat to directly heat the ferromagnetic material.
  • the EP 2 400 052 A1 concerns, inter alia, a dryer in which an induction heating system is used to heat the air.
  • the drum of the dryer has a heating coil of conductive material disposed around the drum.
  • the heating coil is electrically contacted and supplied from outside such that the heating coil is an electromagnetic Field can produce, which act on the drum and this can heat inductively.
  • the US 4,181,846 A relates to a rotary heating device which operates with induction.
  • a rotating drum has at least partially a material which can be heated by means of magnetic induction.
  • An induction heating coil is located close enough to this part of the rotating drum to heat that part of the drum during operation.
  • the drum can be rotated by a motor.
  • the interior of the drum can be heated by means of heat radiation and heat conduction emanating from the inductively heated drum.
  • the JP 2004 135 998 A shows a comparable dryer.
  • the disadvantage here is that the heat within the drum only emanates from the heated drum. This can lead to a very uneven heat distribution within the drum. This may be the case in particular if a lot of laundry is applied to the inside of the drum and this shields thermally against the air inside the drum.
  • JPH06-121898 A relates to a comparable induction dryer in which, however, a fan is disposed on the axis of rotation of the drum to produce a flow of air centrally through the inductively heated drum. This air flow is simultaneously guided past the induction heating coil and its converter in order to use their waste heat to heat the air flow. As a result, a more uniform heating of the interior of the drum is to be achieved.
  • the disadvantage here is that only waste heat for heating the air can be used, which can not have much effect. Furthermore, this heat is available only after a certain period of operation of the induction dryer, if already the drying of the laundry was already at least partially carried out. Furthermore, the inductively generated heat and the waste air generated warm air are related because both are generated by the induction heating coil and its inverter.
  • the electrical resistance heater is an ignition source and can reach temperatures above 350 ° C.
  • an electrical resistance heater can not be used in combination with alternative refrigerants, e.g. R270 (propane) without additional safety measures being taken in this case.
  • R270 propane
  • this also means additional effort and additional costs.
  • An object of the present invention is to provide a tumble dryer of the type described above, which at the same time has a lower drying time than conventional tumble dryer with the greatest possible energy efficiency.
  • a tumble dryer should be created based on a heat pump tumble dryer without changing its heat pump system.
  • Overall, alternatively and / or improved possibilities for drying as well as the hot airing of laundry by means of a tumble dryer should be provided.
  • the present invention thus relates to a tumble dryer with a laundry drum for receiving laundry to be dried and with a heat pump unit for generating process air for drying the laundry in the laundry drum.
  • the tumble dryer can therefore also be referred to as a heat pump tumble dryer.
  • Such dryers are characterized by their high energy efficiency, but have a relatively low temperature range, which can be achieved by means of the heat pump. This can lead to significantly longer drying times. This can affect customer acceptance despite lower energy consumption.
  • the tumble dryer according to the invention is therefore characterized by at least one contactless heating unit, which is designed and arranged to heat the laundry drum contactlessly.
  • Non-contact heating units are all physical principles which are able to bring about heating of the laundry drum without having any contact with the laundry drum, i. without touching the laundry drum. This can be for example a heating by means of induction or by means of infrared radiation.
  • the contactless heating of the laundry drum thereby made possible can be done additionally or alternatively to the drying of the laundry in the laundry drum by means of the process air of the heat pump unit of the tumble dryer.
  • the advantage here is that the laundry drum itself can be heated by the additional heating by means of the contactless heating unit, so that the laundry in the laundry drum can be heated and dried from radially inside through the process air of the heat pump unit and from the outside radially through the non-contact heated laundry drum.
  • This can lead to an improvement in the evaporation of moisture in the laundry to be dried and thus to an improvement in the condensation of the washing machine.
  • a faster drying and thus a reduction of the drying time can be achieved.
  • a multiple of the enthalpy flow introduced by the forced convection by means of the process air for the evaporation of the water in the laundry to be dried can be provided by the heat conduction of the contactless heated laundry drum.
  • a tumble dryer can be made available, which provides not only with forced convection the enthalpy of vaporization, but in addition by the heat conduction of the contactless heated laundry drum.
  • the heat pump can be significantly more efficient, since the heat pump no longer has to compensate for the losses to the environment.
  • the heat conduction of the contactless heated laundry drum and the convection of the process air complement each other in the process.
  • Energy is transferred to the laundry via the heat conduction, whereby the delta of the phase change enthalpy from the process volumetric flow for the evaporation is reduced.
  • This can make more water out to evaporate the laundry to be dried and be removed from this.
  • the process air is not cooled down so much and can absorb more water.
  • the compressor is thereby more efficient, because due to the larger Enthalpiestroms greater overheating in the refrigerant circuit and thus a higher density in the refrigerant compared to a heat pump tumble dryer without additional contactless heating of the laundry drum adjusts.
  • a further advantage is that the additional contactless heating unit can be provided as an additional module, so that this function of the additional contactless heating of the laundry drum can be offered and provided as an option existing heat pump tumble dryer.
  • a further advantage is that the additional non-contact heating unit can also be used in heat pump tumble dryer, in which propane is to be used as refrigerants.
  • a faster heating of the laundry drum can be achieved by the contactless heating of the laundry drum, which can lead to a lower crease of the laundry to be dried.
  • the mechanical load on the laundry can be reduced because the items of laundry rub against one another for a shorter time, which otherwise can lead to a load on the fibers of the items of laundry due to abrasion.
  • the faster drying of the water can be transported faster from the fibers of the laundry, whereby the net weight of the laundry to be dried fall and thus the friction between the laundry items can also be reduced.
  • the laundry drum can be heated to the desired drying temperature of the laundry to start drying and operated at this temperature, the process air has reached its predetermined temperature. This too may favor the reduction of creasing.
  • a gentle drum for a heat pump tumble dryer can be created by the non-contact heating unit, since the creasing of the typical long heating phase at low temperatures and cold wall of the laundry drum of the previously known heat pump tumble dryer can be prevented.
  • the non-contact heating unit is arranged to be fixed radially outside the laundry drum.
  • the non-contact heating unit can be arranged, for example, at a radial distance from the laundry drum of preferably up to 2.5 cm in order to maintain a sufficient distance, so that even during operation safe touches can be avoided, but at the same time can be done an efficient heating of the laundry drum.
  • the fixed arrangement of the contactless heating unit a simple electrical supply can be achieved.
  • a secure and permanently durable positioning and alignment with respect to the rotatable laundry drum can be achieved.
  • the non-contact heating unit can be arranged, for example, at the top or bottom in one of the corners of the housing of the tumble dryer, where, in addition to the cylindrical laundry drum, there is usually sufficient space for an additional contactless heating unit.
  • contactless heating unit can also be arranged integrated, for example, on the condensation tank housing, on a side wall or in another component.
  • the non-contact heating unit is an induction heating unit.
  • This may comprise one or more coils, which may be supplied with a high-frequency alternating current, to induce an inductive heating by means of a primary magnetic field in the radially outer layer of the material of the laundry drum.
  • the laundry drum is for this purpose preferably formed from a ferromagnetic material or has at least partially on a ferromagnetic material.
  • the heating effect on ferromagnetic materials in the after-range of the induction heating unit can be limited, so that unwanted effects on other elements within the tumble dryer can be avoided.
  • the non-contact heating unit is configured to operate only when the laundry drum is rotating. This is to ensure that it does not come to an inadmissible high heating of the laundry drum or sections herebefore and thus of laundry or partial areas of laundry, which rest on the inside of the laundry drum. Furthermore, it is advantageous to operate the contactless heating unit only when the laundry drum is rotating in order to achieve a uniform temperature distribution on the wall of the laundry drum and in the laundry to be dried.
  • the contactless heating unit heats only when the speed of the laundry drum is greater than zero, to prevent local overheating of the laundry drum and to heat the laundry to be dried evenly. Due to the uniform and rapid heating of the laundry drum, the laundry for a not cooled as previously through the wall of the laundry drum but there heated, so that the laundry can be dried faster and can form no creases in the laundry.
  • the laundry drum is designed to be operated at a speed which is as high as possible but low enough to prevent the laundry from being placed against the interior of the laundry drum.
  • the laundry drum should be operated as fast as possible, however, below the contact speed.
  • the laundry to be dried remains permanently on the wall of the laundry drum.
  • no reaction speed should be run in the process.
  • a speed range between -80 rpm ⁇ n ⁇ 80 rpm must be observed.
  • the items of laundry can be heated via the heat conduction of the contactless heated laundry drum and the process air of the heat pump unit.
  • the laundry drum is rotated during operation with a rotational rhythm between 10 U / min and 70 U / min. In this speed range, the uniform heating of the load can be ensured.
  • the laundry items to be dried detach from the laundry drum due to gravity, so that the surface of the laundry drum is impinged by the process air, the water evaporates there and then in the enthalpy stream from the laundry drum to the condenser (heat pump evaporator). can be forwarded.
  • the laundry items not streamed by the process air volume flow and applied to the wall of the laundry drum are deliberately heated by means of the heat conduction of the laundry drum, which are cooled by the wall of the laundry drum without the heating of the laundry drum or at best retain their temperature. As a result, an improved drying performance can be achieved, which can lead to improved efficiency of the tumble dryer and shorter drying times.
  • the non-contact heating unit is configured to be operated with adjustable heating power. Power outputs by the non-contact heating unit in the range of 600 W, 1200 W and 1,800 W can preferably be used.

  • the temperature of the laundry drum can be set as high as possible in order to achieve the highest possible heat conduction.
  • the temperature of the laundry drum should be kept low enough not to damage the items to be dried.
  • the temperature of the laundry drum via the contactless heating unit can be adapted to these requirements in order to achieve an optimum result. Therefore, the speed of the laundry drum decreases, so the performance of the contactless heating unit can be adjusted.
  • the contactless heating unit is designed to be operated with a heating power as a function of the temperature of the process air.
  • the interaction between heat generation by heat conduction of the contactless heated laundry drum and by heat convection of the process air flow can be adjusted to each other in order to achieve an optimal Enthalpiestrom.
