Definitions

  • the invention relates to a surface heating device for heating water or alkali in a tub in a washing machine, with a flat support plate for attachment to the tub, and with a conductor formed as a conductor heating conductor, which is acted upon by electrical energy and is designed to generate heat, wherein the heat is released through the carrier plate to the water.
  • the invention also relates to a washing machine with a tub and such a surface heater and a method for producing a surface heater.
  • Heating devices for heating the wash liquor in the tub of a washing machine are already state of the art.
  • tubular heaters or rod-shaped heating elements are usually used.
  • these have the disadvantage that they are surrounded on all sides by wash liquor and thus must be mounted in a radiator pocket. This creates an additional consumption of water and electrical energy, the so-called "dead fleet”.
  • such tubular heaters are also particularly susceptible to the addition of lime and lint, which in turn can lead to local overheating and thus in the worst case to failure of the device.
  • the surface heating device has an intermediate layer of a good thermal conductivity material such as aluminum, which is connected to the carrier plate and the heating conductor and distributes the heat.
  • heating foils and other flexible heating media are known, which, however, can not be used because of problems in terms of insulation, electrical contact and fixation in the washer.
  • Aêtnwar seen invention is designed for heating water in a tub of a washing machine and includes a flat support plate which can be attached to the tub, in particular such that the support plate conceals a recess formed in a wall of the tub.
  • the surface heating device also has a heating conductor designed as a conductor for generating heat for heating the liquor, wherein the heat is released through the carrier plate to the water.
  • the surface heating device is designed as a sandwich component in which an intermediate layer is arranged between the heating conductor and the carrier plate for uniform distribution of the heat relative to the surface, this intermediate layer being formed from a material which has greater thermal conductivity relative to the carrier plate.
  • the surface heating device consists of a uniform layer composite of the carrier plate, the intermediate layer, the heating conductor and preferably a further insulating layer, wherein the heating conductor may be formed in a meandering shape.
  • the heat provided by the heating conductor is thus homogeneously distributed over the surface by means of the thermally highly conductive intermediate layer and discharged from the intermediate layer through the support plate to the water.
  • Such surface heating device has various advantages: First, thus local overheating can be prevented by addition of lime and lint in the tub, because the intermediate layer provides for a homogeneous heat distribution over the surface of the intermediate layer. This results in a reliable and reliable heating of the liquor in the tub. Compared to a conventional tubular heater heating also a water and energy saving is achieved, for example in the range 6 to 8%. Due to the planar or flat geometry of the surface heater also the addition of lint is avoided in the tub.
  • Another advantage is that due to the poorer thermal conductivity of the support plate these can be easily mounted on the tub, without the heat is transferred to the tub itself. Due to a small thickness of the carrier plate, the heat transfer through the carrier plate to the liquor in the tub is mainly in the direction perpendicular to the carrier plate, while heat transfer in the lateral direction (in the plane of the carrier plate) is minimal due to the poor thermal conductivity of the carrier plate.
  • This has advantages in terms of attachment of the surface heater to the tub. Namely, the support plate can be connected to the tub, for example, by friction welding, while the other components of the surface heater, which are remote from the interior of the tub, do not come into contact with the material of the tub.
  • the intermediate layer has a relative to the carrier plate greater thermal capacity.
  • the intermediate layer can thus store significantly more thermal energy than the carrier plate, which in particular heat accumulation can be avoided and heat losses can be reduced.
  • the intermediate layer is formed from a material whose thermal conductivity of the thermal conductivity of the support plate by a factor greater than 5, in particular a factor greater than 10, is higher.
  • the intermediate layer is formed of a material whose thermal conductivity of the Thermal conductivity of the support plate is greater by a factor which is in a range of from 5 to 20, in particular from 10 to 20.
  • the support plate is formed of stainless steel.
  • This embodiment has advantages in terms of the life of the surface heater. It is namely the support plate, which faces the interior of the tub and thus exposed to the liquor. The design of the support plate made of stainless steel thus corrosion of the surface heater is prevented.
  • Stainless steel also has a thermal conductivity which is relatively low and therefore particularly suitable for the present application. Thus, the heat can be reliably and effectively delivered through the material of the support plate to the liquor, while in the direction parallel to the support plate takes place only a minimal or, if possible, substantially no heat transfer.
  • the thermal conductivity of the carrier plate is preferably less than 20 W / mK.
  • the intermediate layer is formed of a material whose thermal conductivity is greater than 150 W / mK, in particular greater than 200 W / mK. This ensures a homogeneous heat distribution over the entire surface of the intermediate layer and thus for an effective and reliable as well as with respect to the surface uniform heat transfer to the liquor in the tub.
  • the intermediate layer is formed from aluminum.
  • This embodiment has manufacturing advantages, because the aluminum layer can be applied to the carrier plate without much effort, for example by soldering, rolling or welding, in particular friction welding.
  • the heating conductor is preferably applied by thermal spraying, in particular by plasma spraying.
  • This means that the heating conductor is applied in a plasma process, which in particular has the advantage that materials can be used for the heating conductor, which have a relatively high melting point. Such materials can be used particularly advantageously as heating conductors.
  • the surface heater can be inexpensively manufactured by the known plasma deposition process.
  • the surface heating device may also be arched or bent.
  • an adaptation of the geometric shape to the circular Shape of the tub allows.
  • the support plate is inserted within a recess in the tub and thus a portion of the wall of the tub is formed by the support plate, thus flattening in the tub can be prevented.
  • a reliable and well-adhering connection between the tub and the surface heater can be made possible.
  • the invention is not limited to a curved configuration of the surface heating device. It is also possible to design the surface heating device flat or planar, which in turn offers advantages with regard to the production of the surface heating device.
  • the carrier plate has a side region that protrudes beyond the intermediate layer or protrudes laterally, in particular completely around the intermediate layer, over which the carrier plate and thus the entire surface heating device is attached to the tub.
  • the carrier plate as a whole is larger than the intermediate layer, so that said edge region is formed free of the intermediate layer.
  • Such an embodiment of the carrier plate has the advantage that over the edge region, the surface heater can be effectively mounted or fixed to the tub, while the intermediate layer is arranged in register with a continuous recess of the tub and thus does not come into contact with the tub.
  • an additional layer is preferably provided, which is formed from an electrically insulating material.
  • this insulating layer in particular generated by plasma spraying insulating layer, the heating element is then applied directly.

  • the invention also relates to a washing machine with a tub and a surface heating device according to the invention.
  • the tub has a continuous recess which is covered by the support plate, so that the support plate forms an area of a wall of the tub and thereby faces the interior of the tub, while the heating element is remote from the interior.
