Definitions

  • the present invention relates to a continuous-flow heater, in particular for a coffee or tea machine, consisting of a hollow body provided with an inlet and an outlet and an electrical resistance heater which completely or partially surrounds the hollow body.
  • Water heaters of the generic type are known in many embodiments.
  • the electrical resistance heating consists of heating wires or flat radiators which are wound around the hollow body or are completely or partially cast into the hollow body.
  • This design principle has a negative influence on the size of the known instantaneous water heaters as well as their design options.
  • the heating wires surrounding the hollow body increase the total volume of previously known instantaneous heaters, the overall dimensions of previously known instantaneous heaters anyway having to be designed to be quite large in order to provide the heating power required in each case.
  • the present invention has for its object to provide a flow heater of the generic type, which is characterized both by small dimensions and in that its shape can be aligned practically without restriction to the particular use or application.
  • the hollow body from an electrically non-conductive Ma material or is provided with a thin insulating layer and the electrical resistance heater consists of an at least in partial areas of the outer surface of the hollow body printed and sintered on resistance paste.
  • the electrical resistance heater is printed and sintered onto the hollow body, on the one hand an increase in volume of the entire instantaneous heater by the resistance heater itself is practically avoided and on the other hand the advantage is achieved that the instantaneous heater can be largely optimally adapted to its respective use, since in its design, it is practically only necessary to ensure that the hollow body can be printed with an appropriate resistance paste.
  • hybrid heating elements The printing of corresponding materials with appropriate resistance pastes and sintering on of these resistance pastes for the purpose of forming heating elements is known per se under the term hybrid heating elements, so far, however, such hybrid heating elements have been produced and used exclusively as contact heating elements which serve to transfer heat to other components to transfer.
  • hybrid heating elements have been produced and used exclusively as contact heating elements which serve to transfer heat to other components to transfer.
  • the use of conventional hybrid heating elements for instantaneous water heaters would not bring any advantage over the known prior art.
  • a tubular flow heater generally designated by the reference numeral 10
  • This water heater 10 consists of a hollow body 11 in the form of a tube and a resistance paste 12 printed and sintered onto this hollow body 11, which serves as an electrical resistance heater.
  • the hollow body 11 is either made of an electrically non-conductive material or consists of an electrically conductive material which is provided with a thin insulating layer.
  • the hollow body 11 consist of steel, and a thin ceramic coating can be provided as the insulating layer.
  • the resistance paste 12 is then printed and sintered onto this ceramic coating.
  • a pipe end 13 is used as an inlet and the one not shown in FIG. 1 re pipe end 14 used as an outlet for the water heater 10.
  • the instantaneous water heater 10 shown in a perspective view in FIG. 2 again consists of a hollow body 11 with an inlet 13 and an outlet 14 as well as a resistance paste 12 printed and sintered onto the hollow body, which forms the electrical resistance heater for the instantaneous heater 10.
  • the hollow body 11 is also made in the exemplary embodiment according to FIG. 2 from an electrically non-conductive material or is provided with an insulating layer.
  • the resistance paste 12 is printed on the respective hollow body 11 in spiral shapes.
  • 3 and 4 show a further embodiment for a tubular instantaneous water heater 10.
  • the central area of the tubular hollow body 11 is flattened in order to create largely flat surfaces for printing with the resistance paste 12.
  • Inlet 13 and outlet 14 of the instantaneous water heater 10 are left cylindrical in order to be able to connect corresponding hose-like connecting parts to the instantaneous water heater 10 without problems.
  • the instantaneous water heater 10 can also be curved in the form of a tube.
  • FIG. 5 in conjunction with FIG. 6 makes it clear that there are various possibilities with regard to the shape of the instantaneous water heater 10 according to the invention.
  • two pipe sections 16, which run parallel to one another and are connected to one another by a central web 15, can be provided with an electrical resistance heater by means of a printed and sintered-on resistor paste 12, and the two pipe sections can be connected to one another via a connecting piece 17.
  • the tube sections 16 are flattened in order to create a surface that is as flat as possible for printing on the resistance paste 12.
  • any curved hollow body 11 can be provided with an electrical resistance heater in the form of a printed and sintered resistance paste 12 in order to create a continuous-flow heater 10.
  • the water heater 10 is to have a hollow body 11 made of electrically non-conductive material, aluminum dioxide is preferably used.
