Definitions

  • the invention relates to a heating device for flowable media, in particular liquids, wherein the heating according to the invention can be dry in the medium or preferably outside the liquid and the heating on the one hand a liquid inlet and on the other hand an outlet, e.g. a process water outlet for the heated medium can be assigned, so that even small amounts of medium can advantageously be heated.

  • the heating according to the invention can be dry in the medium or preferably outside the liquid and the heating on the one hand a liquid inlet and on the other hand an outlet, e.g. a process water outlet for the heated medium can be assigned, so that even small amounts of medium can advantageously be heated.
  • Heating devices of this type are used in particular for heating water, for heating beverages and the like, it being generally important to have stored a sufficiently large supply of liquid at all times. Most of the time, however, the amount of heated liquid required per unit of time is so small in relation to the storage capacity that the energy required to heat the entire storage capacity is in a very unfavorable ratio to the energy extracted. In addition, in order to be able to bring the entire storage capacity to the desired temperature of the partial quantity as quickly as possible before removing a heated partial quantity, a very high connection value is required for the heating, which can lead to difficulties with regard to the mains protection, in particular with electrical heating.
  • the invention is also based on the object of avoiding disadvantages of known designs and, in particular, of creating a heating device of the type mentioned, which makes it possible in a simple manner to use only a subset of the total storage capacity which is intended for the particular removal, essentially independently of the remaining amount of storage in heat up for a short time and with a relatively low connected load for heating.

  • the heating energy applied is greatly reduced or substantially even prevented from any flow heat transfer from the partial quantity to the remaining storage quantity, essentially only to the partial quantity available for removal by the use outlet, which can be removed immediately when the desired temperature is reached .
  • the partial quantity is advantageously heated in a heating chamber, which can lie essentially within the liquid store or within the stored liquid such that the major part of its outer surface is washed by this liquid. It doesn't just make one achieved very compact training, but also achieved that possible heat transfers through the chamber wall do not lead to heat loss, but serve to preheat the remaining amount of liquid in the liquid storage.
  • the heating chamber can consist partly or entirely of metallic materials, such as stainless steel, plastic and / or ceramic, depending on the temperatures for which the heating device is designed, the types of liquids to be heated and the level of insulation between the heating chamber and the rest of the liquid storage is desired.
  • the heating chamber is formed over the largest part of its circumference by a component which can be removed from the liquid reservoir by easy detachability and which is expediently open on one side to its full inside width, so that good cleaning options for all inner surfaces of the heating chamber result.
  • the heating device according to the invention can only be used for heating or heating liquid below the boiling point, in which case the use outlet expediently adjoins the heating chamber in the deepest region.
  • the heating device or the heating chamber can be provided for steam generation, the use outlet for the steam expediently adjoining the heating chamber in the uppermost region.
  • the heating chamber can be open at the top over its full width, but can be separated upwards above the maximum liquid level in relation to the rest of the liquid reservoir, or it can be connected to an outlet line narrower in relation to its width, especially if its top side is below the maximum liquid level. which is expediently passed through the liquid reservoir.
  • the heating chamber or its steam outlet and the liquid storage in a common Arranged pressure vessel so the vapor pressure generated by heating can also be used to convey liquid under pressure, ie if necessary upwards above the maximum liquid level.
  • the liquid delivery from the heating chamber can also be effected by steam pressure inside the heating chamber or within the line leading out of it, for example, by generating steam bubbles in the heating chamber or in the correspondingly narrow line, which eject the heated liquid upwards.
  • a usage outlet is also led away from the liquid storage device, which can be provided to rise upwards from its inlet opening in the direction of flow when the liquid storage device is exposed to the vapor pressure of the heating chamber is.
  • the device according to the invention can also optionally be used for heating liquid and for generating steam by changing the liquid level in the liquid store.
  • the liquid level is low, it is easier to generate steam, especially if this liquid level is below the top of the heating chamber, that is, it protrudes upward from the stored liquid.
  • the heating device is in most cases better suited for heating the liquid below the boiling point.
  • the heating can also be manually adjustable in at least two stages in such a way that steam is generated at higher power outputs and heated liquid at lower power outputs.
  • the heating can be designed for any energy source or for optionally different energy sources, it is preferably designed as an electrical heating system, the heating resistor of which is formed by a tubular heating element or the like. It is expediently located outside the liquid or the steam and thus in the drying process. It is conceivable, in addition to heating the heating chamber, to provide separate preheating heating for the remaining liquid store or to arrange the heating for the heating chamber in such a way that it also preheats the liquid storage directly, but there is a particularly simple embodiment if only direct heating occurs the heating chamber is provided and the remaining liquid storage is completely free of direct heating.
