Definitions

  • the invention relates to a kettle according to the preamble of the preamble of claim 1.
  • a boiler bottom of a water boiler for producing steam or hot water is coated after repeated use (usually within a few weeks) by lime deposition and calcium carbonates in argonite form.
  • This coating has a strong water-repellent effect, whereby a heat transfer (for example, a heating coil of the boiler) is hindered in the water so that a fast and economical production of hot water / steam is no longer possible.
  • a heat transfer for example, a heating coil of the boiler
  • the limestone layer also leads to poor heat conduction and thereby may also adversely affect a function of an electric heater, such as in a steaming apparatus for human hair according to DE102004031208A1, which is hereby fully disclosed.
  • a limestone layer of 1 mm already leads to a 10% higher energy expenditure.
  • the steam boiler (depending on the quality of the tap water) should usually be descaled once or twice a week with a chemical descaling agent or distilled water should always be used. However, this is usually omitted for time or / and cost reasons.
  • the invention is based on the object, in a generic same kettles, the usual limestone on a boiler bottom, which is formed by cooking or heating tap water mar shove.st by simple measures also to avoid environmental aspects and to ensure a high degree of maintenance of descaling, so that chemical Descaling agents are practically no longer necessary and business interruptions are practically avoided.
  • This object is achieved according to the characterizing part of claim 1.
  • the ball 5 have a diameter of 5 to 15 mm. In order to cover the bottom of the vessel 3 sufficiently and give the balls 5 still opportunity to be able to move, 45 pieces of balls 5 per boiler 1 have proven to be optimal.
  • a corresponding ceramic ball 5 costs about 1, 3 euro cents; a filling with handling about 1 €, which makes the use of the invention extremely inexpensive.
  • the dissolved calcium deposits also occur in the boilers 1 without ceramic balls 5.
  • the limescale deposits except on the bottom of the boiler 3 on the overlying water displacer from.
  • the barber does not do it with the necessary care or not at all. This leads to operational failures of the apparatus 31 for steaming human hair.
  • the balls 5 in this embodiment have a diameter of about 11 mm and an average weight of about 3.5 grams. This creates a weak noise by the movement of the balls 5 during the cooking process, which is drowned out by the bubbling of the kettle 1 and therefore no person as such would notice or even annoying.
  • the weight of the balls 5 is too high, because it is to be understood that the balls 5 practically do not jump up, but move minimally on the bottom of the vessel 3 rolling and only a few 0.01 mm are raised. This is sufficient to greatly inhibit the formation of layers; and more importantly, the little 0.01 mm thick coating which forms over time is water absorbent (no surface tension) and is not water repellent as in cooking without the ceramic ball filling.
  • Fig. 1 shows a new, cut kettle 1 (section l-l of Fig.7), i. without lime layer 10 and before first operation of the steam treatment hood 31 (FIG. 9) (P7).
  • the boiler 1 After filling 45 pieces of ceramic granules 5, wherein the bottom of the tank 3 is substantially completely provided with balls 5, the boiler 1 is filled to the maximum with water. Then follow cooking periods with manual timing of 60 minutes and at maximum temperature. After the time has elapsed, the boiler 1 is refilled to its maximum and then the next cooking period is restarted.
  • Fig. 2 shows the boiler bottom 3 after 7 cooking periods. There is no water-repellent limescale layer 10 (each shown schematically dotted) available.
  • Fig. 3 shows the boiler bottom 3 after 19 cooking periods. There is no water-repellent limestone layer 10 available.
  • Fig. 4 shows the boiler bottom 3 after 45 cooking periods. There is no water-repellent limestone layer 10 available.
  • Fig. 5 shows the boiler bottom 3 after 80 cooking periods. There is no water-repellent limestone layer 10 available.
  • the kettle 1 is freed from the lime deposit 10 by means of the enclosed tablet or a similar commercial chemical descaling agent. In doing so, the usage and safety regulations for the respective agent must be observed. After chemical descaling, rinse the kettle 1 well.
  • Fig. 6 shows the boiler 1 with 45 pieces of ceramic granules 5 and the descaling tablet 11 (in a blister pack) as a retrofit kit (otherwise the boiler 1 factory already filled with the ceramic granules 5 or preferably with pyramids 8 and tetrahedrons 9 accordingly.
  • the calcification process can be further successfully delayed if the boiler 1 after use, preferably 1 time a day, shaken, emptied and rinsed thoroughly. As a result, the lime components in the residual water are flushed out of the boiler 1.
  • FIG. 7 shows in a cutaway detail the boiler 1 in a device 31 (FIG. 9) for the treatment of human hair by means of water vapor 12.
  • FIG. 8 shows a side view of the boiler 1 according to section VIII - VIII of FIG. 7.

  • balls 5 optionally with pyramids 8 or tetrahedrons 9 or in inchesweiser Combination with each other.
  • FIG. 11 corresponds to FIG. 1, with tetrahedrons 9 (FIG. 14) being used instead of the balls 5. It has been found in further experiments with ceramic pyramids 8 (FIG. 13) or ceramic tetrahedrons 9 (FIG. 14) that a further improved descaling effect was achieved.
  • the ceramic pyramids 8 (FIG. 13) and tetrahedron 9 (FIG. 14) in this exemplary embodiment have an edge length of approximately 15 ⁇ 15 mm (weight of the pyramid approx. 2 g) and, of course, a larger contact area than balls 5 As a result, a larger area is of course also covered during the cooking process, and thus the lime layer 10 is better removed.

  • the limescale can set 10, by the mechanical movement of the ceramic parts 6 (articles 7) on the floors 3 or walls of the boiler 1 prevents lime coating formation or at least greatly delays time.
  • the ceramic parts (items 7) can be adapted in shape and size to the respective space conditions of the heating vessel. This allows flexible reaction to all geometries of heating vessels.
  • the filling must be carried out so that the ceramic parts 7 are kept in motion by the cooking process itself, or by the water flowing through.
  • the ceramic parts 6, 7 artificially enlarge the surface on the floors 3 and walls of the water tank (boiler 1, 1.1) and gradually wipe off any already existing coverings from the walls. This self-cleaning of the vessels (boiler 1, 1.1) is always possible if you fill the vessels (boiler 1, 1.1) of a lime coating 10 either immediately when new or as retrofitting with the ceramic parts 7.
  • the ceramic parts 7 are made of 90% aluminum oxide, are heat stable, impact resistant and toxic harmless. They can therefore also be safely used as calcification inhibitors or calcification inhibitors in the food sector, without tedious rinsing operations (as required and mandatory, for example, when using chemical descaling tablets or powders are required).
  • the microparticles of lime substances dissolved by the grinding process are also rinsed out during the refilling process or during the discharge process and no longer adhere to the vessel bottom 3 and the container walls.
  • the ceramic parts 7 are suitable, for example, for use in larger boilers, such as in hot water heating systems and industrial heating systems, etc. It must be determined depending on the operating conditions of the boiler, the optimal size (shape and weight) of the ceramic parts 6,7, so that the ceramic parts 6,7 with the water flow conditions can keep in a slight movement.
  • the subject of the invention is suitable for all imaginable applications in which lime deposits on the boiler bottom 3 or container walls can settle and these lime deposits 10 the
