Description

Wall-mounted washbasin

Field of technology

The present technical solution relates to an extension washbasin which is installed on a flat base plate, with a washbasin bowl open upwards and with a base formed on the underside, which has at least a partially surrounding support edge by means of which the washbasin is seated on the base plate.

The adjustable washbasin is installed on a flat base plate, which is a bottom cabinet or worktop. The washbasin bowl is located completely above the surface of the base plate. The drain is led through a recess in the base plate into a siphon located under the base plate.

Prior art

The edge of the washbasin base lying on the base plate is usually provided with a silicone jointing compound, which protects against the ingress of dirt and moisture. However, the manual application of the silicone grout by the installation technician is time consuming and the result is often not visually pleasing. In addition, the silicone material may become loose due to aging or its color may be damaged by UV radiation.

The essence of the technical solution

The aim of the technical solution is therefore to design an extension washbasin that can be easily and hygienically installed.

This object is achieved by a wall-mounted washbasin having the features of claim 1, the preferred embodiments being set out in the dependent claims.

In the case of an extension-type washbasin of this type, the technical solution stipulates that the support edge has a step or groove towards the inside of the base in which a resilient seal is inserted. The resilient seal seals the abutment edge against the base plate, i.e. the bottom cabinet or the worktop, so it is not necessary to apply another resilient seal. The seal is not visible from the outside and is not exposed to UV radiation, which would lead to premature aging of the sealing material. In addition, no gap is visible between the support edge and the base plate when the seal is recessed.

The seal is preferably made of an elastomer, eg based on silicone, rubber or polyurethane. The seal can be made as a profile seal made of solid material or with a chamber profile. A polyurethane-based foam sealing tape can also be used as a seal, which gradually expands after compression to form a tight connection. In all these cases, the seal can be glued to the support edge, in particular in the area of the step or groove.

The extension washbasin preferably has a drain opening into the base area. Via a corresponding waste pipe, the drain in the base can be connected to a siphon located under the base plate, by a recess in the base plate. The installed drain pipes can thus be hidden.

The drain can also be equipped with a shut-off or a closable drain valve. This can be operated by an eccentric pull rod attached to the basin mixer. The rod is connected to the drain valve plate and with its help the valve is raised or closed. The eccentric drawbar also extends through the inside of the base so that it is not visible.

- 1 CZ 33953 U1

In a preferred embodiment, the extension washbasin has a washbasin area with a bottom and a circumferential wall. In this case, it can be ensured that the wall on the outside passes smoothly into the supporting edge, which forms the area of the base. The area of the dishwasher inside may form a concave container open upwards.

In a preferred embodiment, the extension washbasin is made of a mineral casting or of a ceramic material, in particular sanitary ceramics or sanitary porcelain. The above materials are suitable for the sanitary sector. In addition, the step or groove can be integrated integrally during the production of the washbasin. The technical solution also includes the possibility of producing a stainless steel washbasin. In this case, the step or groove can be punched out. The seal that is used in the area of the step or groove can alternatively be made of polyurethane-based foam.

Explanation of drawings

Other advantages and features of the present technical solution will be apparent from the following description of exemplary embodiments with reference to the drawings, in which:

Fig. 1 is an isometric view of an extension washbasin;

Fig. 2 is an isometric view of the extension washbasin of Fig. 1 - bottom view;

Fig. 3 is a detailed sectional view of the lower support edge of the extension washbasin of Fig. 1; and FIG. 4 is a detailed view of the support edge - a bottom view, in section.

Examples of technical solution

Figures 1 and 2 show an extension washbasin L. The washbasin comprises a concave bowl 2 open upwards with a circumferential side wall 3 which extends into the bottom 4. At the deepest point of the bottom 4 there is a drain 5 with a drain valve 6.

The side wall 3 extends downwards on the outside of the washbasin 1 into the base 7 and is terminated by a support edge 8, by which the washbasin 1 is placed on a base plate 9 (see Fig. 3), e.g. on a bottom cabinet or worktop.

A bracket 10 with an opening into which the fitting 12 is installed is formed on the back of the washbasin 1. On the underside of the washbasin 1, mounting holes 14 with a threaded insert are located on both sides in the base 7, which serve to attach the washbasin 1 to the base plate 9. .

In the exemplary embodiment, the support edge 8 is formed circumferentially. Alternatively, however, it would also be possible to adjust the back of the washbasin so that it can be fixed to the wall of the room, so that the support edge would only reach the wall connection and end there or pass into the connecting edge bent at right angles upwards to connect it. to the wall.

The support edge 8 has a step 15 on the inside of the base, in which a resilient seal 16 is placed and glued. Figures 3 and 4 show a step 15 and a seal 16. The support edge 8 is located on the base plate 9 in this figure 3. Seal 16 lying in the recessed step 15 is dimensioned so that it abuts the base plate 9 and thus prevents the penetration of dirt and moisture. It is therefore not necessary to apply an additional silicone sealant. As an alternative to the step 15, a groove can be formed on the underside of the support edge 8 in which the seal 16 is accommodated.
