Description

The invention relates to a sink consisting of a deep-drawn to a trough steel sheet with an enamel coating.

Wash basins or sinks are known in a variety of embodiments and designs. They are made of ceramic, plastic or sheet metal, in which case either a stainless steel sheet or a standard steel sheet is deep-drawn into a trough. The steel sheet must, so it does not corrode then, be provided with a coating, which is preferably high quality enamel. Of these enamelled washbasin essay basins are sold, which are placed on a plate or a pad or insert basins, which are used in a vanity with a support plate. For this purpose, the support plate is provided with a recess which is larger than the outer contour of the trough. Vanities with support plate are widely known. The washbasin may have a base cabinet, but it may also consist of only one plate.

From the DE 196 13 527 C2 is a washstand with a support plate is known in which the sink has an outwardly projecting edge which is bent at right angles from the trough, and whose free ends are angled back down in the direction of the trough bottom. With this edge, the sink is placed on a arranged on the support plate projection.

The plate of the washbasin and the sink are made separately. The plate can be made of wood, a wood material, plastic or stone or artificial stone. The inside of the trough may be formed with substantially straight side walls and a plane running floor or spherical or truncated pyramidal.

In addition to the functionality is a sink or a vanity with sink the task of beauty of form. The sink should be as elegant as possible in bathrooms or kitchens.

The invention has for its object to produce a sink or a washstand made of sheet steel, which is structurally simple and meets the requirements of functionality and design.

To solve this problem, the washbasin consists of a to a trough with a perpendicular thereto extending upper edge of sheet steel, which is coated at least on one side over the entire surface with enamel, the edge just ends without further bending at its free end and the thickness D of the Steel sheet in the edge meets the condition: 4 mm ≥ D ≥ 2 mm. The edge can be deep drawn with the trough or welded to the trough.

By this embodiment, an extremely flat edge is formed, which allows the wash basin so insert into the cutout of a plate of a washstand that the visible side of the edge is flush with the top of the plate. The sink is thus seamlessly integrated into the plate. Due to the particularly thin design of the edge with a thickness of the steel sheet of preferably 3 mm, the notch of the plate around the cutout around can be made very flat. This leads to a shortening of the production time and to an extension of the service life of the milling tools, with which the notch is made, which is particularly extreme is advantageous if granite plates are used for the washstand, which are very hard and therefore difficult to work. The fact that the notch is narrow, the plate can be made thin, which on the one hand can positively influence the design of the washbasin, but on the other hand also reduces the cost, especially when using expensive stone or artificial stone slabs. Since the edge of the sink is made very thin, it is also possible in a slightly simpler design of the washbasin to use the sink in the recess without notching, so that the thin edge rests flat on top of the plate. Due to the preferably only 3 mm height of the edge a shapely impression of the top is met here.

The steel sheet preferably does not have a thickness of more than 4 mm at any point and, in particular, is preferably 3 mm thick throughout.

When the sink is flush with the top of the panel, preferably its edge is at least partially embedded in a seal which laterally projects beyond the edge at the bottom, so that moisture can not penetrate between the bottom of the rim and the notch.

When the washbasin is supported by its edge on top of the plate, a seal is preferably arranged between the edge and the plate which terminates with the free end of the rim.

The edge can be angled at one free end once or twice, in which case the angle or angles of the angle are substantially 90 °. This bend creates a wall finish.

The washbasin 1 is made by deep drawing a steel sheet 2 having a thickness D between 2 and 4 mm, preferably 3 mm. It has a trough 3, which can take any cross-section. In the drawing, it is essentially rectangular or with rounded side edges.

The trough 3 is followed by a peripheral edge 4, which is formed integrally with the trough 3 and was produced by bending the steel sheet 2. The edge 4 may also be welded to the trough 3. The edge 4 is running - like FIGS. 4 and 8th show - at right angles to the trough 3, or its vertical axis A, and just without further bending off. Its thickness D is 3 mm. In the middle of the trough 3, a conventional water drain 15 is provided. Water flows are not shown and can be arranged arbitrarily. The side walls 12 of the trough 3 can be substantially vertical or oblique, ie cylindrical-cylindrical in the case of a round basin, or pyramid-shaped in the case of a rectangular or square basin. The steel sheet 2 is completely covered with an enamel layer 11 so that it does not corrode.

At the in FIG. 4 illustrated installation situation, the plate 6 is provided in the recess 7 with a notch 9, which is slightly deeper than the thickness D of the edge 4. In the notch 9 is between the edge 4 and the plate 6, a rim 4 embedding seal 10th intended. The edge 4 lies in the same plane as the upper side 6 'of the plate 6, and the seal 10 terminates seamlessly between the visible side 4' of the edge 4 and the upper side 6 'of the plate 6, so that there is a completely full-surface finish on the top 6' of the washstand.

FIG. 5 shows the partial view of a washstand according to visual arrow IV after FIG. 3 ,

FIG. 8 shows the partial view in cross section according to arrow VIII FIG. 7 , The plate 6 of the washbasin not shown is provided with a cutout 7, in which the sink 1 can be used. The cutout 7 is larger than the trough 3. The sink 1 is supported with its edge 4, which may be formed circumferentially or is provided on at least two opposite sides of the trough 3, on the top 6 'of the plate 6 from. Between the bottom 4 'of the edge 4 and the plate 6, a seal 8 is inserted, which seals the sink 1 against the plate 6, so that no moisture between the edge 4 and the plate 6 can penetrate.

The plate 6 of the washbasin may be made of any material. Usual is a wood material, a plastic, stone or artificial stone. The thickness of the enamel layer 11 is very thin compared to the thickness D of the steel sheet 2. The edge 4 of the sink is therefore only slightly thicker than 3 mm. The depth of the notch must be performed only by the thickness of the seal 10 deeper than the thickness of the edge 4. Through this low material removal, the notch 9 can be made much faster than before, which reduces production costs. In particular, with high-quality material that is difficult to work, such as granite, this naturally also increases the service life of the tools, which further reduces the production costs. Since the depth of the cutout is small, the thickness of the plate 6 can be chosen correspondingly low, which can improve the optical properties of the washstand. The sink according to the invention can consequently be used selectively as a design element.

In the embodiment of the washbasin after FIGS. 9 and 10 a free end 4a of the edge 4 is angled upwards. With this angled part 4a, the sink 1 is in its installation situation on the wall of the room. At the in FIGS. 11 and 12 shown embodiment of a sink, the part 4a is angled at its free end again. This again angled part 4b abuts in the installation situation of the washbasin 1 also on the wall of the room, so that a cavity between the washbasin 1 and the wall, not shown here sets. The angles α and β for the first and second angling are 90 °.
