Definitions

  • the invention relates to a humidifier with an electrical heating device and a container for receiving the water to be evaporated by means of the heating device and with a housing surrounding the container at a distance and consisting of a jacket and a base.
  • the water tank is made of metal, since this material can withstand the heating that occurs during operation of the humidifier most permanently and is also resistant to hydrolysis, while other material has not yet proven suitable.
  • the process known as hydrolose in which the water split to a small part of the ions reacts with substances dissolved in it to form an acid, becomes more intense with increasing temperature, which must be taken into account in a humidifier because of the constant heating of the water when selecting the material. Due to the water container becoming hot, the humidifier must also have an insulating outer housing that provides protection when the humidifier is touched and also allows it to be transported during operation.
  • the housing is primarily made of plastic material with known humidifiers, since this material g as a poor conductor of heat good insulation intrinsically owns. Since there is also an air layer between the water tank and the housing, the housing does not heat up excessively and can be touched safely.
  • the aim of the present invention is to simplify the manufacture of a humidifier of the type described and to make it more economical, which is possible if a few parts have to be assembled from different materials.
  • the above-mentioned aim can be achieved according to the invention by the fact that the humidifier initially has mentioned type of casing and the container closed at the bottom or having a bottom recess covered by the heating device are integrally formed and consist of plastic material and that the heating device is resiliently attached to the tank bottom.
  • the bottom of the container made of plastic material can expand to a different extent than the heating device during the heating that occurs during operation.
  • the housing jacket and the container form a cylindrical double-walled ring body, on the upper edge of which the housing jacket and the container are integrally connected. Furthermore, projections which are integrally formed with this can be expediently arranged on the bottom underside of the container for the purpose of fastening a housing base at a distance from the container bottom.
  • the housing jacket and the container made of polypropylene and form a plastic injection molded part.
  • This humidifier has the advantage that fewer parts have to be put together during manufacture and, as was previously the case with a metal water tank, it is not necessary to take into account different expansion coefficients of the materials, so that there is an overall significant weight Cost savings result.
  • the air humidifier has a housing jacket 10 and a water container 11 which is integrally connected to it, which together form a cylindrical, double-walled ring body, on the upper edge 12 of which the housing jacket 10 and the container 11 are integrally connected.
  • the container 11 also has a circularly delimited recess 13 on the bottom, which is covered by a circular heating device 14 in outline, so that this heating device forms part of the bottom of the container. Since the water container 11 forms a part reduced to a ring due to the bottom recess 13, there is a favorable shape for the production of the double-walled ring body consisting of the casing 10 and water container 11 as a plastic injection molded part.
  • Polypropylene is used as the plastic material, which material is resistant to hydrolysis even at high water temperatures and also has an optically good appearance. In addition, this material is not statically charged, so that it does not attract dust and dirt. In addition, this material has good fluidity during processing in an injection mold. Of course, it is also possible to design the water container 11 with a closed bottom and to arrange the heating device 14 above this bottom.
  • the ring body is simultaneously formed on the bottom underside of the container with the protrusions 15, which are formed in one piece and are arranged radially outside the base recess 13 provided in the middle and are used for this purpose, at a distance from the bottom of the water tank 11 to attach a housing base 16.
  • the housing jacket 10 and the water tank 11, which are connected to one another at the upper edge at 12, and the projections 15 on the underside of the tank bottom consist of an injection molded part.
  • the heating device 14 rests on an annular seal 20 at the edge of the bottom recess 13, at which edge the heating device is clamped by means of a plate 21 screwed against the underside of the container, a compensating ring consisting of rubber still being located between this plate and the underside of the container bottom 22 is located. With the help of the two rings, the heating device is attached to the bottom of the container in a floating manner, so that the bottom of the container can expand as a result of the heating that occurs during operation.
  • the heating device 14 consists of a heating head 23 with raised ribs, in which heating head a circular cross-section heating element 24 is embedded, to which the electrical connection cable 25 is connected.
