Definitions

  • the invention relates to a home-range instantaneous water heater for passing a flowable medium and with a heater for heating the medium and a household appliance with such a home-range instantaneous water heater.
  • the heater may consist of a burner which heats the line with a gas-assisted flame and above that the flowable medium.
  • a heating device in the form of a current-carrying resistance wire which heats up and heats the wire wrapped by the resistance wire and above it the medium contained therein.
  • JP 2004-135998 Generally known are JP 2004-135998 .
  • at least one or more coils for generating the alternating magnetic field are arranged outside the laundry drum. Due to the laundry load of the laundry drum, the laundry drum at a high rotational speed during a spin cycle in vibrations, which run the laundry drum out of control. Due to this, it is disadvantageously required that the induction coils for generating the alternating magnetic field are arranged at a large distance from the drum. In order to heat the drum sufficiently, therefore, correspondingly large electrical currents must be applied to the coils.
  • induction furnaces for heating metals are generally known from plant engineering.
  • the home-range instantaneous heater has a line with at least one flow channel for passing a flowable medium (liquid and / or gas), as well as a heater for heating the medium, wherein the heating means for generating an alternating magnetic field, a coil and further at least one having the alternating magnetic field heatable radiator.
  • Such an arrangement thus exploits that a primary energy, which is provided by the coil as a primary winding, is transmitted by magnetic induction in the secondary-side mounted radiator. Utilizing the transformer or eddy current principle, heat is generated in the radiators and transferred from them to the adjacent medium. By the inductive power transmission from the coil to the radiator, a power loss can be kept low, which can operate such a water heater energy saving.
  • the primary energy source (coil) and the radiator or radiators are electrically isolated from each other (galvanically isolated) so that can be dispensed with contacts and cables for the transmission of electricity to the area to be heated.
  • a low-priced and more corrosion-resistant construction is achieved.
  • electrical components are arranged far away from any fluid-carrying components and thus a contact protection of live parts is ensured, which increases the reliability.
  • Another advantage is the possible conversion of the water contained in the "lime" in a lime form, which is no longer on device surfaces such. As radiators, attaches, which further increases the reliability.
  • Such a home-range instantaneous water heater can be used in particular in a household appliance such as a hot water instantaneous water heater, a washing machine, a tumble dryer, a washer-dryer or a dishwasher.
  • a household appliance such as a hot water instantaneous water heater, a washing machine, a tumble dryer, a washer-dryer or a dishwasher.
  • a domestic hot water heater but also household installations such as heating or sanitary concern.
  • the at least one heating element can be introduced into the at least one flow channel, since in this way a large-area contact surface with the flow medium can be achieved in a structurally simple manner.
  • the at least one radiator may in particular have a plurality of individual radiators, which advantageously leave a sufficient gap for the flow medium. Accordingly, the ratio of the surface, which is in contact with the medium to be heated, and the internal volume of the radiator, adjustable to obtain a high heat transfer rate and thus a low response time.
  • individual heaters having a spherical basic shape, since these allow a volume of space and, between the balls, a passage volume for the medium in a particularly advantageous embodiment.
  • balls have a relatively smooth and vortex-inhibiting surface.
  • the at least one heating element can have an electrically conductive single heating element.
  • the single heater may comprise a ferromagnetic material, preferably iron-based (ferrite, steel, etc.).
  • the at least one radiator can have at least one secondary winding ("secondary coil”), in particular a short-circuited secondary winding.
  • secondary coil By the magnetic alternating field generated by the coil (“primary coil”), a current is generated in the secondary coil, whose winding may have one or more windings, which is converted into heat due to the short circuit.
  • a resonant converter is advantageously used.
  • the secondary coil has a resistance heating wire as a winding wire.
  • the coil may be provided with heating resistors as a load.
  • the radiator may have a plurality of individual radiators each having a secondary coil or a plurality of secondary coils.
  • the at least one radiator having a coil core of a ferrite-containing material, for. B. in the form of a shell core.
  • the coil for generating the alternating magnetic field may be arranged for easy production and obtaining a high reliability outside a wall of the conduit.
  • the flow channel is not or at least not substantially shielded for heating the radiator by the wall, the wall is advantageously at least partially or partially formed free of an electrically conductive material, for. B. made of plastic.
  • the alternating magnetic field can penetrate substantially undisturbed into the flow region with the at least one heating element located therein.
  • the at least one radiator is at least partially formed as a part of the wall.
  • a plurality of spaced apart wall sections of a wall of the conduit may be formed as such a radiator, ie electrically conductive, in particular metallic, especially ferromagnetic material.
  • An advantage of such arrangements is an external thermal shield, so that the heat generated in the wall regions of the conduit is preferably emitted only in the direction of the medium through which the conduit flows.
  • the wall may also have heating, projecting into the at least one flow channel heat transfer elements such as longitudinal ribs, etc.
  • the medium may in particular comprise air, water or a lye, as it is used as a working medium or as a heat transfer medium in the home.
  • the at least one heating element can come into contact with moisture, ie in particular is arranged within the flow region of the medium, it advantageously has corrosion protection. Corrosion protection is particularly useful, since ferromagnetic materials tend to oxidize or "rusting". In particular, in the case of lines through which water or a liquor flows as the medium, coating on the outside of the radiator with corrosion protection is therefore advantageous.
  • at least the flow medium exposed areas of the radiator may consist of a stainless material.
  • the conduit is tubular and externally wound with an inductor coil as the coil, and a heating area with the at least one radiator is within the coil-wrapped area in the wall and / or in the at least one flow channel educated.
  • FIG. 1 Haus Scheme instantaneous water heater 16, shown by way of example, of a laundry drying apparatus (washer-dryer or tumble dryer) H has a tubular conduit 1.
  • the line 1 has a wall 2, which has a flow channel. 3 encloses.
  • the outer surface of the wall 2 is wrapped with a coil 5, which generates an alternating magnetic field in the volume enclosed by it upon application of an alternating current and thus serves as an induction coil.
  • a flange 4 is formed on the wall 2, which serves as Abloisschutz for a coil 5.
  • the wall 2 is made of a non-conductive material, for. As plastic, designed to provide the electromagnetic alternating field generated by the coil 5 as low as possible shielding.
  • the individual heaters 6 are made of a material which heats up when the alternating current is applied by means of the coil 5 due to eddy currents induced therein. While the material may generally be an electrically conductive material, particularly a metal, to achieve high efficiency, a ferromagnetic or high ferromagnetic material is used, particularly a corrosion protected ferrous material.
  • a control device 8 as control and regulating electronics serves to receive a power provided by a power supply connection 9 and to apply an alternating current to the coil 5 via coil connection lines 10 such that the coil 5 generates the alternating magnetic field in the flow channel 3 in the region of the heating elements 6 and Heating element 6 is heated or heated. When flowing around the heated radiator 6, the medium also warms M.
  • a temperature sensor 7 is arranged in or on the flow channel 3, which serves to detect the output temperature of a medium M, which flows through the interior 3 in the direction of the temperature sensor 7 and while the radiator 6 lapped.
  • the control device 8 is designed to regulate a temperature by means of a detected by the temperature sensor 7 and applied via a signal line 11 to the control device 8 temperature signal.

  • the water heater 17 off FIG. 2 shows up on the radiator 6 * the same components as the water heater 16 FIG. 1 , why opposite FIG. 1 especially the radiator 6 * is described in detail.
  • the individual heaters 19 each have a shell core 14 made of ferrite material, in which a short-circuited secondary winding 15 is housed. While an alternating magnetic field is applied to the secondary windings 15, these are heated and thereby heat the ferrite core 14. The ferrite cores 14 in turn heat the radiator 6 * , and this the flow medium M.
  • FIG. 1 a variety of individual radiators can be installed FIG. 1 each be wrapped with secondary windings.
  • FIG. 1 an arrangement of a plurality of such bodies can be arranged behind one another or next to one another in the interior 3.
  • the individual radiator shown as an example FIG. 1 must not be spherical, but may also be shaped differently, z. B. disc-shaped or annular.
  • the wall or at least a portion of the wall be configured as the radiator.
  • the wall 2 then corresponding electrically conductive, in particular ferromagnetic, sections or is formed as a whole ferromagnetic, so that the alternating magnetic field generated by the coil 5 heats the wall of the line.
