Definitions

  • the present invention relates to a sanitary tub made from an enamelled steel sheet with a tub-shaped molded body which has a peripherally projecting outer edge which is at least partially flat, and a method for producing a sanitary tub.
  • the DE 10 2018 132 073 A1 discloses a method for producing a sanitary tub, in which a tub-shaped molded body is first coated with a layer of enamel, and then the coated molded body is cut off at least in regions at one edge.
  • the geometry of the sanitary tub can be individually cut to size on the surrounding edge and adapted to an installation situation.
  • it can be coated again or provided with a cover, which is comparatively complex and has optical disadvantages.
  • a tub-shaped molded body is provided with a circumferentially protruding outer edge which is at least partially planar, the edge being rounded at least in certain areas on one end face and the rounded edge being coated with enamel.
  • the flat edge can be cut individually, since the design of the cut edge is not subject to any restrictions like the production of a folded edge.
  • the rounding of the face of the rim allows the rim to be enamel coated with the face with high quality, since there is no sharp edge, which can lead to greatly different layer thicknesses and chipping of the coating.
  • the rounding of the cut edge thus replaces the bevel (flanging), such as that found in the DE 39 22 789 C1 is known.
  • the rounded area of the edge is homogeneously rounded on the end face and has a radius of between 0.8 mm and 3 mm, in particular 1.1 mm and 1.5 mm. This allows the face to be effectively and evenly coated with enamel.
  • the protruding edge is preferably cut out in a curved manner, at least in certain areas, with the curved cut edge being provided in particular at a distance from the corners of the trough-shaped molded body.
  • the curved edge can, for example, have a radius greater than 50 mm, so that the trough-shaped molded body can be accommodated in different edge geometries, for example in a rounded or oval contour when viewed from above.
  • the edge preferably runs flat all the way around and essentially parallel to a bottom of the trough-shaped molded body.
  • the base of the trough-shaped molded body is arranged at a slight incline to a drain opening, with the peripheral edge preferably being aligned essentially parallel to this base and thus protruding horizontally in the installed position.
  • At least one recess or step can optionally be cut out on this edge in order to be able to adapt the edge to a predetermined installation situation.
  • at least one punched opening can be provided on the edge, for example for attaching holders, shelves or other components.
  • opening edges around the opening are also rounded and coated with enamel.
  • a tub-shaped molded body with a protruding peripheral edge is first formed from a steel sheet, for example with a thickness of between 1.5 mm and 3.5 mm.
  • the edge of this blank is then processed by a cutting process, for example by laser welding, the edge of the trough-shaped molded body being cut off at least in regions along a cutting edge.
  • This cut edge on the edge of the shaped body is rounded at the end at least in regions, preferably completely, in order to then coat the shaped body with the edge with a layer of enamel at a high temperature.
  • the coating can be carried out completely on an upper side and on the rounded edge, while optionally flaws or non-coated areas can be left free on the underside.
  • the sanitary tub produced in this way can be individually cut to size at the edge in order to then be adapted to a special installation situation.
  • the circumferential edge preferably runs out flat, in particular parallel to a bottom of the trough-shaped molded body, with a flat section of the edge being cut off along the cutting edge. This facilitates the cutting process that cuts off only plate-shaped sections.
  • the edge is preferably rounded by machining, for example by milling or filing.
  • non-machining shaping can also be used, for example rounding by forming or punching the cutting edge.
  • Non-machining deformation and a machining process can also be combined with one another in order to obtain a homogeneous rounding of the cut edge.
  • the cutting off preferably takes place along a cutting edge which is curved at least in some areas. In contrast to folding an edge, this means that any arcuate contours can be produced on the edge.
  • the cut edge and/or the edge is rounded all the way around after cutting.
  • a recess and/or a step is preferably produced at the edge.
  • an opening can optionally be punched out at the edge, with the edges of the opening being rounded before coating, so that the opening can be used to install further components.
  • a sanitary tub 1 comprises a tub-shaped molded body 2 made of enamelled sheet steel, which has an upper edge 3 that protrudes laterally.
  • the sanitary tub 1 is designed as a bathtub, but can also be designed as a shower tray or sink.
  • a drain opening 5 is provided on a bottom of the trough-shaped molded body 2 .
  • a face 4 at the edge 3 is according to Figure 1C rounded and has a radius R between 0.8 mm and 3 mm, in particular 1.1 mm. Due to this rounding, an enamel coating can also be applied to the end face 4 of the edge 3 with a uniform layer thickness.
  • the trough-shaped molded body 2 with the edge 3 is coated with enamel at least on the upper side and the end face 4 .
  • a bottom be entirely or partially also coated with enamel on the edge or the trough-shaped molded body.
  • the sanitary tub 1 made of enamelled sheet steel can be individually adapted to an installation position by cutting off and rounding off the planar edge 3 in the desired shape.
  • Figure 2A a sanitary tub 1 is shown in which the edge 3 is cut out in a rounded manner on the end faces of the trough-shaped molded body 2, with the rounding extending essentially uniformly over the entire end face.
  • the radius of the cutting edge can be greater than 20 cm, and the curved contour can merge into a straight section on a longitudinal side of the trough-shaped molded body.
  • a recess 10 can also be cut out on the edge 3, for example in the form of a semicircle or a recess with a different contour.
  • FIG 2B a sanitary tub is shown in which the edge 3 is arranged asymmetrically around the tub-shaped molding 2, since only a narrow edge 3 is formed on the left side and a wide edge 3 is formed on the right side.
  • Several openings 11 are punched out in the wide edge 3, which can optionally be provided in order to fix further components, for example shelves, fittings or other components there.
  • the edges of the openings 11 can optionally also be rounded and then coated with enamel.
  • FIG. 2C another sanitary tub is shown which has an asymmetrical edge 3 on which an angular recess 12 is cut out.
  • FIG 2D a sanitary tub is shown with an edge 3 which has a step 13 on one side which is provided adjacent to a longitudinal edge of the tub-shaped molded body 2 .
  • the representation of Figures 2A to 2D can be combined with one another as desired and are intended to show that the planar edge 3 can be cut off with any desired contours.
  • a trough-shaped molded body 2 is formed from a steel sheet, in which a drainage opening 5 is introduced at a bottom.
  • the trough-shaped molded body 2 comprises an edge 3 which is designed to run out flat and extends essentially parallel to the floor.
  • the edge 3 on the uncoated sheet steel blank is larger than the future edge 3 of the sanitary tub 1.
  • the edge on the longitudinal sides of the trough-shaped molded body 2 can be severed along cutting edges 7, so that strip-shaped sections 6 are severed.
  • Strip-shaped sections 8 can be separated from the edge 3 along cut edges 9 on the end faces of the trough-shaped molded body 2 .
  • Examples of sanitary tubs made according to the blank figure 3 can be produced, show the Figures 4A to 4D for rectangular designs in plan view, with the examples of the blank also Figures 2A to 2D are producible.
  • the cut edge 7 or 9 is rounded off at least in certain areas on the end face 4, preferably the entire end face 4 on the circumference of the trough-shaped molded body 2 is rounded off at the edge 3.
  • Rounding can be done using cutting methods, such as milling, or non-cutting methods, such as punching, or by a combination of cutting and non-cutting methods.
  • the shaped body 2 is coated with a layer of enamel which is burned in at high temperatures, for example at over 800°C.
  • the sanitary tub 1 produced in this way is then cooled and can then be installed with the individually tailored edge 3 .
