Definitions

  • the invention relates to a hot water tank according to the preamble of the main claim.
  • Known hot water tanks of this type have a dimensionally stable inner container which is surrounded by the thermal insulation jacket and which is produced by the blowing process or is composed of individual molded parts which are welded to one another.
  • This multi-part design requires a relatively high amount of tools and assembly. Disposal is also problematic because the inner container and insulating jacket are made of different materials.
  • the arrangement according to the invention with the characterizing features of the main claim has the advantage that a special inner container is not required at all and as a result the manufacturing outlay is markedly reduced.
  • the combination of inner container and insulating jacket according to the invention into a common, dimensionally stable foam body also enables or facilitates recycling because it is only a single substance, preferably polypropylene.
  • the inner wall of the foam body can be lined with a water and vapor diffusion-tight film, which consists of the same material as the thermal insulation foam and is fused with it during the foaming process.
  • the film For the production-appropriate application of the film, it is proposed to design it as a film sleeve which, prior to the foaming process, is filled with a liquid or steam to form a bubble corresponding to the shape and size of the storage space.
  • the arrangement of a film is unnecessary if the inner wall of the foam body due to the action of pressure and temperature water and vapor diffusion-tight hardened.
  • the foam body can be made in one piece or composed of several parts, preferably of two half-shells, which are tightly connected to one another.
  • the foam body is provided with hardened or stiffened wall areas for connection with fastening means, such as a support flange for an electric heating element, fittings for connecting lines or means for attaching the memory to a support part.
  • fastening means such as a support flange for an electric heating element, fittings for connecting lines or means for attaching the memory to a support part.
  • the foam body also functions as a load-bearing outer wall, such as the rear wall, and that, in addition to a separate inner container, there is also no separate load-bearing outer wall part.
  • the hardening or stiffening of the corresponding wall areas of the foam body can also be achieved by the action of pressure and temperature on these areas.
  • the foam body can be stiffened in the corresponding areas by molded parts of the same or foamed form.
  • FIG. 1 shows a longitudinal section through a container of an unpressurized small electrical store according to the first exemplary embodiment
  • FIG. 2 shows a longitudinal section through a container according to the second exemplary embodiment at right angles to the longitudinal section according to FIG.
  • the container is formed by a dimensionally stable foam body 10 made of polypropylene, which encloses a storage space 12, from which two channels 14, 16 lead to openings at the upper end wall 18 of the foam body 10.
  • the inner wall 20 of the foam body 10 surrounding the storage space 12 and the walls of the channels 14, 16 are made water and vapor diffusion-tight by the action of pressure and temperature, so that a separate inner container is unnecessary.
  • the rear wall 22 of the foam body 10 is stiffened by a molded part 24 made of polypropylene so that the foam body can be attached directly to a supporting wall.
  • An installation opening 26 is provided for introducing an electric heating element and is surrounded by a molded part 28 of the same material.
  • the mouths of the channels 14, 16 on the end wall 18 are provided with stiffening, molded parts 30, 32 of the same material.
  • the molded parts 24, 26, 30, 32 are already fused in the foaming mold with the foam introduced, so that they form a recyclable unit with the foam body 10.
  • the front wall 34 of the foam body 10, its end wall 18 and the two side walls which are not visible in FIG. 1 are covered by an embossed or glued-on film 36 of the same material, so that they are decorable without any additional, non-material covering parts.
  • the inner wall 20 of the foam body 10 surrounding the storage space 12 could also be lined with a water and vapor diffusion-tight film which is designed as a sheath which is in front of the Foaming process is filled with a liquid or steam to a bubble corresponding to the shape and size of the storage space.
  • a foam body 40 forming the storage container consists of two dimensionally stable half-shells 40a, 40b, which are tightly connected to one another.
  • the mutually facing surfaces of the two half-shells 40a, 40b are each covered with a water and vapor diffusion-tight film 42a or 42b.
  • the foam body 40 has the same structure and the same features as the foam body 10 described above.
  • the inner walls of the foam body 40 could also be made water and vapor diffusion-proof instead of being lined with a film by the action of pressure and temperature.
