Description

[0001] The invention relates to a countertop washbasin, having a base, a basin wall projecting from the base with a basin edge lying in one plane, a drain opening arranged in the base and arranged off-center thereon and a support surface arranged on the base for placing the countertop washbasin on a support plate.

[0002] Sinks are open-topped containers with a drain to the sewer system and a faucet attached to the sink, from which water is drawn. Sinks are mounted, for example, on a vertically oriented wall, with fixtures located near the mounting surface. A shelf is often provided to the side of the faucet, for example, for placing soap or other items. The sink has a recess, at the lowest point of which is the drain or connection to the sewer system.

[0003] In addition to washbasins that are mounted on the wall, there are also washbasins that are recessed into a vanity top. For this purpose, the washbasin has an outward-projecting, circumferential ledge that is shaped and sized to cover the mounting hole within the vanity top and protrudes beyond the mounting hole. The washbasin bowl is led through the mounting hole and, when installed, is located predominantly below the vanity surface. The tap is usually mounted on the vanity top, and the drain opening in the basin bowl is also positioned at the lowest point of the washbasin so that the water can drain away completely. When installed, only the top of the washbasin is visible; this extends from the edge of the basin inwards and towards the drain hole.

[0004] Countertop washbasins differ from inset washbasins in their installation. Instead of being wall-mounted or installed in an opening within the washbasin, countertop washbasins are placed on a vanity top, so that the outside of the washbasin is also visible and the washbasin is almost entirely above the countertop. The faucet is located either in the washbasin or on a wall. The drain opening is located in the base of the basin at the lowest point. The water is drained into the sewer system via a suitable pipe or drain opening, which is routed through a comparatively small opening within the washbasin.

[0005] One problem with state-of-the-art countertop washbasins is the lack of protection against splashing water and the increased water consumption when the washbasin is used to collect water, for example to soak or rinse objects.

[0006] The object of the present invention is therefore to provide a countertop washbasin that avoids or reduces the disadvantages of the prior art and allows flexible installation.

[0007] This object is achieved by a countertop washbasin having the features of the main claim. Advantageous embodiments and further developments of the invention are disclosed in the subclaims, the description, and the figures.

[0008] The countertop washbasin with a base, a basin wall protruding from the base with a basin rim lying in one plane, a drain opening arranged off-center in the base, and a support surface arranged on the base for placing the countertop washbasin on a support plate. The base, which can also extend continuously from the basin rim to the drain opening, forms the surface on the inside of the countertop washbasin that usually absorbs the water and directs it to the drain opening. The support surface, with which the countertop washbasin is mounted on a support plate, is arranged on the outside or underside of the countertop washbasin on the base and at least partially surrounds the drain opening. Advantageously, the support surface extends completely around the drain opening.The support surface preferably forms a plane; at least the support surface is shaped to correspond to the surface of the support plate, such that the support surface can be securely placed and mounted on the support plate. The support surface is, in particular, flat and oriented at an angle relative to the plane formed by the basin rim. If the support plate is generally aligned horizontally, the support surface is also oriented horizontally or horizontally when mounted. In the claimed subject matter, the basin rim plane is oriented at an angle or incline to the support plate, such that it is possible to mount the opening of the washbasin, which is formed by the basin rim and circumferentially delimited, in different orientations relative to the user or the fitting.Positioning the drain opening off-center allows the drain opening to be positioned at the lowest point when installed. At the same time, the sloped base and basin wall, which extends from the base toward the basin's edge, provide improved splash protection. The sloped position can also reduce the amount of water required to reach a desired level when the drain opening is closed, allowing for lower water consumption with a closed sink, in addition to allowing for use with running water.

[0009] In one embodiment, the base is dome-shaped, conical, or pyramid-shaped. In particular, with a dome-shaped base or a dome-shaped design of the base together with the basin wall, the drain opening with the contact surface assigned to the drain opening can be arranged at any point on the base without restricting the drainage function. Alternatively, the base is conical, in particular designed as a truncated cone, wherein the tip of the cone or truncated cone can be rounded. As an alternative to the rotationally symmetrical conical shape, the base can also be pyramid-shaped, i.e. constructed from a plurality of essentially flat surfaces, wherein, to ensure complete drainage function, it is advantageous to arrange the drain opening in a downwardly curved or inclined region of a side surface.The pyramid-shaped design facilitates secure mounting on the support plate, as it provides an enlarged, flat surface for resting on the washbasin.

[0010] In one embodiment, the pool edge and the pool wall are arranged around a central axis, with the drain opening offset from the central axis. In one embodiment, the central axis forms an axis of symmetry; in particular, the floor can be designed perpendicular to the central axis in cross-section, and / or the pool wall and thus also the pool edge can be round, square, or oval.

[0011] In one design of the countertop washbasin, the basin wall adjoins the floor and is oriented either parallel or inclined to the central axis. With an inclined design of the basin wall, it can taper conically towards the basin rim so that, as seen from the opening of the basin, the basin wall extends outwards towards the floor. This can achieve improved splash protection. Alternatively, the incline can be designed so that the basin wall widens outwards towards the basin rim, thereby making the basin easier to access. The basin wall can also be oriented parallel to the central axis, which, for example, leads to a cylindrical structure of the basin wall if the contour of the basin rim is rounded in the basin rim plane.The basin floor connects to the basin rim or wall and forms the basin's recess with the drain opening. As an alternative to a rounded design or a rounded design with a curved basin wall, the basin wall can also be polygonal, in which case a closed recess is always formed by the basin, with the exception of the drain opening, of course.

[0012] To improve the drainage behavior from the washbasin, the base is designed to be inclined or curved towards the drain opening, so that it is ensured that the drain opening is positioned at the lowest point of the washbasin when installed.

[0013] The inclination of the support surface to the basin edge plane is between 5° and 25°, whereby all inclination gradations in between are possible, in particular the inclination is between 10° and 20°, preferably 15°.

[0014] The countertop washbasin can be designed, in particular, as a metal, plastic, ceramic, or glass basin and, in particular, has a surface coating to ensure the washbasin's usability for as long as possible. Especially when made of metal, the base body can be easily manufactured using a deep-drawing process or another forming process.

[0015] The support surface is designed, in particular, as a flat shoulder in a conical or dome-shaped recess, to which the drain opening is connected, optionally with means for attaching the countertop washbasin to the support plate. The support surface is, in particular, annular, ensuring even support of the countertop washbasin on the support plate.

[0016] The floor can have facets or flat surfaces in sections, and the pool wall can also have a surface composed of many flat individual surfaces in addition to a smooth inner and / or outer surface.

[0017] In one design, the base forms an apex, which is defined as the greatest vertical distance from the basin's rim to the floor. With a horizontal installation of the basin's rim, the apex would be the lowest point of the basin's basin. The drain opening is positioned at a distance from the apex and, due to the slope of the support surface, continues to form the lowest point of the countertop basin when installed.

[0018] The invention is explained in more detail below with reference to the figures. Like reference numerals in the figures denote like components. They show: Figure 1 - a countertop washbasin in perspective view; Figure 2- a countertop washbasin in a side view; and Figure 3 - a countertop washbasin in a bottom view.

[0019] In the Figure 1A countertop washbasin 1 is shown in a perspective view obliquely from the front. The countertop washbasin 1 has a base 10 and a basin wall 20 protruding from the base 10. The basin wall 20, together with the base 10, forms the trough-shaped or bowl-like washbasin, which has a drain opening 40 in the base 10, which is arranged at the lowest point when the washbasin is assembled. In the illustrated initial example, the drain opening 40 is closed by a closure. The washbasin 1 is bounded at the top by a basin rim 30; the basin rim 30 is closed and, in the illustrated embodiment, has a circular shape.The basin wall 20 is formed in a ring-shaped manner and, in the illustrated embodiment, is conically shaped, wherein the diameter of the basin wall 20 decreases from the basin edge 30 towards the floor 10, so that the washbasin widens and opens towards the user.

[0020] In the Figure 2the countertop washbasin 1 is shown in a side view. The base 10 is dome-shaped and accordingly has a circular circumference, to which the basin wall 20 is correspondingly connected. In the direction of the basin rim 30, the diameter of the basin wall 20 increases, resulting in a slightly conical shape that widens outwards and forwards towards the opening of the basin. Due to the circular circumference of both the base 10 and the basin wall 20, the countertop washbasin 1 has a central axis 2, which is also designed as an axis of symmetry. The basin rim 30 lies in a plane 25, which is drawn at a distance from the actual basin rim 30 for improved visibility. The central axis 2 is perpendicular to the basin rim plane 25 and passes through the center of the base 10, which forms an apex 15.The position of the apex 15 is where the distance between the perpendicular to the basin edge plane 25 and the base 10 is greatest. If the basin edge plane 25 were tilted so that it was horizontal, the apex 15 would be the lowest point of the washbasin. The base 10 does not have to form a mathematically perfect spherical dome. In the illustrated embodiment, the outer contour of the base 10 is essentially spherical, with the exception of a support surface 15 formed on the base 10 for the countertop washbasin 1, which is formed on a bulge and surrounds the drain opening 40. The inside of the base 10 of the washbasin is essentially spherical, except for the drain opening 40 and the drain plug arranged therein, wherein a recess inclined at an angle in the direction of the drain opening 40 is machined and formed in the base 10 to form the drain opening 40.For example, if the base material of the base 10 is a metal, the recess can be introduced into the base 10 as part of a forming process. This recess ensures that the drain opening 40, which is located centrally within the outwardly extending shoulder, is located at the geodetically lowest point of the washbasin 1 in the assembled state.

[0021] The support surface 50 is designed so that it can be placed on a flat support plate. The support plate is usually oriented horizontally and the support surface 50 is in the mounted state, as shown in the Figure 2is shown, is aligned substantially parallel to the surface of the support plate. A plane 55 passing through the support surface 50 would not be oriented parallel to the basin edge plane 25 in the assembled state of the countertop washbasin, but would be inclined thereto. The two planes 25, 55 would intersect at an angle of between 5° and 25°, in particular in the case of nickel between 10° and 20°, preferably at an angle of 15°. Accordingly, the central axis 2 is oriented inclined to the direction of gravity G in the assembled state, wherein here too the angle between the direction of gravity G and the central axis 2, which is perpendicular to the basin edge plane 25, is between 5° and 20°, in particular between 10° and 20° and preferably 15°.

[0022] The drainage opening 40 and thus also the contact surface 50 surrounding the drainage opening 40 is formed decentrally on the base 10 and positioned offset from the apex 15. Due to the annular design of the contact surface 50, which is in the Figure 3 As can be seen, the countertop washbasin can be rotated in any orientation on the level 55 in the support surface 50, so that a simple and easy adjustment of the desired orientation of the opening of the countertop washbasin can be achieved.

[0023] In the Figure 3the underside of the washbasin 1 is shown. The annular support surface 50, which is flat, is arranged concentrically to the circular drain opening 40. The dome-shaped base 10 forms an apex 15 which, in the assembled state, is not positioned centrally on the base 10 and does not form the geodetically lowest point of the countertop washbasin in the assembled state. If the basin wall 20 is designed to taper conically towards the basin rim 30, the opening of the countertop washbasin becomes smaller and provides improved splash protection. Due to the inclined orientation of the basin rim plane 25 relative to the support surface 50, a water jet from the fitting can be introduced tangentially into the washbasin in order to increase splash protection.
