Definitions

  • the invention relates to a vacuum cleaner, in particular a canister vacuum cleaner, with a housing constructed of a plurality of housing parts.
  • Such a vacuum cleaner is used in particular in the household sector and usually has a movable on the ground vacuum cleaner housing, in which the individual technical functional components are arranged.
  • the housing can usually insert a suction hose which is typically connected via a suction pipe with an end suction nozzle.
  • a canister vacuum cleaner is also a device subject to high mechanical stress
  • conventional canister vacuum cleaners have a housing designed as a plastic injection-molded part, which is usually composed of several injection-molded parts.
  • plastic injection molding complex and therefore very expensive injection molding tools are required, the production of which is both very time-consuming and very expensive. Since even minor design changes require a new injection molding tool, even comparatively minor model changes are very time- and cost-consuming.
  • the invention has for its object to provide a vacuum cleaner, in particular vacuum cleaner, in which can be realized cost-effective and with little expenditure of time different model variants.
  • the object is achieved by a vacuum cleaner with the features of claim 1.
  • at least one of the housing parts of the housing is formed of a support member and an attached thermoforming element.
  • the carrier part determines the shape and the mechanical function and immediately assumes the mechanical support function of the housing part.
  • the deep-drawing element forms at least largely the shape predefined by the carrier part, thus covering in particular the carrier part and forming the outer surface of the housing part or at least part of the surface.
  • the housing part is therefore constructed in the manner of a sandwich construction, wherein the same carrier parts are used for the different model variants, and different deep-drawing elements are used to differentiate the different models.
  • the carrier part preferably consists of a mechanically stable plastic, or of metal, in particular light metal.
  • thermoforming element The particular advantage in the use of a deep-drawing element is to be seen in the simple and inexpensive production of such a deep-drawing element.
  • no elaborate and expensive injection molding tools are required. Rather, the forming during deep drawing is very simple and flexible.
  • plastics which differ, for example, in their properties, such as the choice of material, color, surface finish, surface design, etc. Since this is a forming process, there are also very large freedoms in the design of the surface, in particular can be easily integrated special motifs, manufacturer logos, etc. easily.
  • To produce the thermoforming element usually a plastic plate is pulled over a forming tool and plastic deformed so that the desired final shape is achieved.
  • the wall thickness of the drawn thermoforming element is for example in the range between 0.5 and a few millimeters.
  • the deep-drawing element does not have sufficient mechanical stability to take over mechanical support functions. In the present case, therefore, preferably no or only a slight mechanical support function is assigned to the deep-drawing element. Rather, the deep-drawing element is supported and supported by the carrier part. The deep-drawing element is therefore drawn in a form-fitting manner over the carrier part, in particular in the manner of a hood.
  • the term "conforming to shape” means, in particular, that the deep-drawing element adapts in all areas to the outer contour of the carrier part.
  • the carrier part and the deep-drawing element are therefore designed in particular in the manner of negative-positive parts, which lie flat against one another over their entire contour.
  • the support member is formed as a plastic injection-molded part.
  • the support member is further formed as a support grid.
  • This is for example a plastic part or metal.
  • the support grid saves material and costs while maintaining the same mechanical functionality.
  • the support grid therefore has at least material perforations or grid-like struts or is designed in the manner of a honeycomb structure.
  • the carrier part comprises a foam part.
  • the carrier part may also be formed overall as a foam part.
  • a suitable plastic and a suitable foam density it is possible to condition the foam part with regard to different requirements. In principle, it is generally possible, even with a foam part all mechanical support and fastening functions to design, if a sufficiently solid foam is used.
  • the carrier component can be optimized, for example, with regard to sound absorption in a housing region close to the motor.
  • several thermoforming elements used differ from each other. As a result, it is possible, depending on the technical or other requirements, to use regions of differently configured thermoforming elements for different housing parts.
  • thermoforming elements differ in this case, in particular with regard to the material used, with regard to the wall thicknesses and / or to different surface textures. By choosing different wall thicknesses, for example, the heat flow from the housing interior to the outside as the inherent rigidity of the thermoforming element can be adjusted. Due to the different choice of material, the thermoforming element in
  • thermoformed foot switch etc. are made particularly robust.
  • the acoustic properties can also be adjusted selectively and in areas.
  • thermoforming element is attached to the support member by gluing.
  • the executed in sandwich construction housing part is in preferred developments optionally or in combination a vacuum cleaner cover, another cover, an operating element or part of an operating element, a housing part of an accessory or a wheel or part of a wheel. All housing parts are in this case arranged in particular movable on another housing part or on a chassis forming a floor o group.
