kitchen sink

The following invention relates to a sink with a worktop and with a sink insert which is accommodated in a recess in the worktop.

Such sinks are widely known and are generally provided as base units in fitted kitchens. In previously known sinks, the sink insert is inserted into a recess in the worktop, whereby the sink insert is fixed in place when installed by having an edge area that rests on the worktop. The edge area of previously known sink inserts thus forms the support for the sink insert on the worktop.

Such known sinks have the disadvantage that there is a gap between the edge of the sink insert and the surface of the worktop, in which dirt can collect and which is very difficult to clean due to the generally small size of the gap. Another disadvantage of known sinks is that the sink inserts always have to be cleaned at least in the area on the worktop.

The edge area protrudes above the surface of the worktop, which can affect the overall visual impression of the sink. In addition, the formation of the edge area mentioned above requires additional manufacturing effort in the case of previously known sink inserts.

It is the object of the present invention to further develop a generic sink in such a way that the sink insert is easy to manufacture and that no gaps that are difficult to clean form between the surface of the worktop and the sink insert.

This problem is solved on the basis of a generic sink in that the sink insert has bevelled or rounded outer edges that taper downwards from the top of the sink insert, and in that the recess in the worktop also has bevelled or rounded edges, so that the recess tapers downwards from the top of the worktop. The outer dimensions of the sink insert and the size of the recess decrease accordingly from the top of the sink insert or the worktop towards the respective underside. This provides a sink in which the sink insert is received and held in the worktop recess in that the outer edges of the sink insert and the edge areas of the recess are bevelled or rounded accordingly, so that the sink insert is simply inserted into the corresponding recess in the worktop from above. This does not require the edge areas of previously known sink inserts that serve as a support, so that their production is correspondingly simplified.

Due to the lack of an edge area of the sink insert, there are no gaps between the surface of the worktop and the sink insert, so that the problem of soiling this area is effectively prevented.

A further advantage is that, if the dimensions of the recess and the sink insert are designed accordingly, the sink insert can be flush with the top of the worktop or, if required, can be lowered relative to the surface of the worktop. Both the flush version and the recessed arrangement of the sink insert ensure that the overall impression is visually uniform and that there are no gaps or protruding edges on the worktop, so that the problem of dirt in this area does not arise. Of course, the sink insert can also protrude above the top of the worktop if required.

In a further embodiment of the present invention, the sink insert and the recess in the worktop are circular. This has the advantage that the manufacture of both the recess and the sink insert is relatively simple, since no rounded corner areas are required. Of course, the present invention also includes all other conceivable shapes, such as an oval design of the sink insert and the recess in the worktop or an essentially rectangular or square design, advantageously with rounded corner areas.

The outer edges of the sink insert and the edges of the recess in the worktop can be conical and bevelled at an angle of 5.5° to the vertical. With such an inclination, the sink insert seals very well against the recess. The conical design has the advantage that the corresponding outer edges of the sink insert and the edges of the recess in the worktop can be manufactured relatively easily. In addition to a conical design, any other shape is also conceivable, for example a rounded design of the outer edges and edges.

In a further embodiment of the present invention, it is provided that the sink insert has a multiplex chipboard at least in the area of the outer edges. Such a chipboard can be used advantageously because it is a waterproof material. The multiplex chipboard is usually covered by the corresponding outer area of the sink insert, which is generally made of stainless steel.

The sink insert can be made of metal and/or ceramic and/or plastic and the worktop can be made of stone and/or wood and/or a coated material and/or metal and/or plastic.

It is particularly advantageous if the coated material is a coated chipboard, as this can result in cost advantages.

In a further embodiment of the present invention, the outer edges of the sink insert are sealed against the recess using silicone or a rubber seal. The silicone is applied to the entire circumference of the sink insert in the area where the sink insert borders the recess in the worktop.

The rubber seal mentioned is preferably an O-ring with a diameter of 0.3 mm.

It is advantageous if the outer edges of the sink insert are glued to the recess.

In a further embodiment of the present invention, it is provided that the worktop has a base body and an insert that encompasses the recess, which is connected to the base body of the worktop on its outside and has the beveled or rounded edge on its inside. In this case, the recess is not surrounded and formed by the base body of the worktop, but by an insert that is in

a correspondingly larger hole or recess in the base body of the worktop. The insert is connected to the base body of the worktop on its outside and has the bevel or rounding of the recess according to the invention on its opposite inside. The recess in the base body in which the insert is accommodated can, but does not have to, have a bevel. It is possible for the base body of the worktop to be provided with a straight hole into which the insert is inserted.

The recess in the worktop can be circular and the insert can be designed as a ring.

The insert can be screwed and/or glued to the base of the worktop. A resilient connection between the insert and the base of the worktop is required, as the worktop insert holds the sink insert and must be designed to be resilient.

In a further embodiment of the present invention, the insert is designed with groove-shaped depressions on the outside facing the base body. This allows a well-sealed connection to be made between the insert and the base body of the worktop, so that it can be prevented that, for example, water can pass through the gap between the insert and the base body.

In a further embodiment of the present invention, the insert has one or more projections which are accommodated in grooves in the base body of the worktop. The grooves or projections serve, on the one hand, to provide a secure and resilient connection between the insert and the base body of the worktop and, on the other hand, to prevent liquid from penetrating through the area, for example an annular gap, between the insert and the base body of the worktop.

-6-

According to a further preferred embodiment of the present invention, the base body of the worktop has a coating on its upper side, with one of the grooves being arranged directly below the coating. This has the advantage that a projection of the insert inserted into this groove is arranged directly below the coating of the base body of the worktop, so that with appropriate design or gluing, it is already possible to effectively prevent liquid from penetrating the area below the coating or between the insert and the base body at this point. The penetration of water not only has the disadvantage that the liquid would collect below the sink insert, but that the penetration of water into the base body can also cause the coating to peel off, which is undesirable.

In a further embodiment of the invention, the space between the groove end and the projection of the insert is filled with a filling material and/or adhesive. This results in a very good sealing connection between the insert and the base body or the coating.

It is also possible for the projection to have a grooved surface. This results in a good seal between the groove and the projection of the insert.

The insert can be made of an elastic material, such as PVC or any other material with this property.

Further details and advantages of the present invention are explained in more detail using an embodiment shown in the drawing.

as well as the adjacent areas of the base body of the worktop and the sink insert as shown in Fig. 16.

Fig. 1, above shows in the left illustration a schematic cross-sectional view of a sink insert 200 accommodated in a recess 102 of a worktop 100. The sink insert 200 is in

-8th-

Fig. 1, shown schematically at the top right. The sink insert 200 has bevelled, i.e. tapered, outer edges 202 that run from the top downwards. These are accommodated in a recess 102 in the worktop 100, with the recess 102 having correspondingly bevelled edges 104. The edges 104 are designed in such a way that the recess 102 tapers from the top of the worktop 100 to its underside, as can be seen from Fig. 1, above. As an example, an angle of 5.5° is given for the inclination of the slope, which results in a particularly tight connection between the outer edges 202 of the sink insert 200 and the edge 104 of the recess 102. In the embodiment according to Fig. 1, the sink insert 200 is round. As indicated in Fig. 1, middle illustration, the worktop 100 also has a round recess 102, the edges 104 of which also run from top to bottom, so that the size of the recess 102 decreases downwards from the top of the worktop 100. The outer edges 202 of the sink insert 200 and the edges 104 of the recess 102 are parallel as shown in Fig. 1.

The worktop 100 can, for example, comprise the materials stone, wood, a coated material such as a coated chipboard, metal and/or plastic or any combination of these materials.

Fig. 1, below, shows an embodiment in which the worktop 100 consists of a base body 106 and a ring 108 arranged thereon. The ring 108 has the beveled edges 104 of the recess 102, while the recess of the base body 106 for receiving the ring 108 has vertical edges.

In all cases, the sink insert 200 is attached in the same way as the plug, which is inserted into the recess 102 of the worktop 100. The edge area between the sink insert 200 and the recess

-9-

102 is sealed with silicone or by means of a rubber ring seal, which advantageously has a diameter of 0.3 mm.

Depending on the design of the bevels, the installation of the sink insert 200 into the recess 102 is always carried out from above. The round design of the sink insert 200 and the recess 102 always allows a perfect execution and guarantees a very good seal with the advantageous angle of inclination of 5.5 ^c .

Fig. 2 shows a schematic view of a sink designed as a kitchen base unit 400 with a worktop 100 and a sink insert 200 accommodated in a recess 102. Here too, the sink insert 200 is round, which enables the above-mentioned relatively simple design of the sink. The shape of the actual sink 300 is independent of this and can be chosen as desired.

Fig. 3 also shows a schematic top view of a base cabinet 400 with worktop 100 and sink insert 200. This has only one sink 300, which is rectangular with rounded corners. Fig. 3, below, shows a cross-sectional view of this arrangement. The right half of the image shows a worktop 100 in which the base body 106 itself has beveled edges 104, which are in contact with the correspondingly beveled outer edges 202. The left half of the image shows an embodiment in which the worktop 100 has a base body 106 and a ring 108 arranged on it, the latter having the beveled edges 104 of the recess 102. In both cases, the edges 104 of the recess 102 and the outer edges 202 of the sink insert 200 have an angle of inclination of 5.5 degrees.

Fig. 4 also shows a schematic plan view of another embodiment of a base cabinet 400, which has a sink insert 200 with

-10-

different sized sinks 300. The sink insert can have any utensils, such as the soap dispenser 302. The eccentric 304 serves as an operating element for opening or closing the drains of the sinks 300.

Fig. 5 shows a further embodiment of a base cabinet 400 in which the sink insert 200 is provided with inclined grooves 306 which run at an angle of 2% to the horizontal. This ensures that the water always runs back into the sink 300.

Fig. 6 shows cross-sectional views of an embodiment of the sink according to the invention without and with a ring 108 serving as an insert. Fig. 6, top, shows the sink insert 200, which is accommodated in the beveled recess 102 of the worktop 100. The views according to Fig. 6 only show the edge areas of the sink insert 200 or the worktop 100. The sinks themselves are not shown. The edge area of the sink insert 200 according to Fig. 6, top, consists of a water-resistant multiplex chipboard 204. On this is the corresponding edge area of the sink made of steel, preferably stainless steel. As can be seen from Fig. 6, top, the contact surface between the sink insert 200 and the edge 104 of the recess 102 is essentially formed by the multiplex chipboard 204. This is glued to the recess 102 and/or sealed using silicone or a rubber ring. On the top of the worktop 100 there are milled recesses that form grooves inclined at 2% to the horizontal for water drainage.

The angle of inclination of the outer edges 202 of the sink insert 200 and the edges 104 of the recess 102 relative to the vertical is 5.5 °.

The worktop according to Fig. 6, above, is preferably made of stone or wood.

Fig. 6, below, shows an embodiment in which the worktop 100 is constructed from a base body 106 and a ring 108. The ring 108 is connected to the base body 106 by means of screws 120. The ring 108 is made of metal or plastic. It has grooves 110 on its outer circumference, which effectively prevent moisture or a liquid from penetrating into the gap between the ring 108 and the base body 106. On its inner side, the ring 108 has the beveled edges 104.

The worktop 100 or its base body 106 is provided with a coating 116, for example melamine. The seal between the ring 108 and the sink insert 200 is achieved by means of silicone or an O-ring seal with a diameter of 0.3 mm.

The worktop 100 as shown in Fig. 6 below is made of coated chipboard. The sink insert 200 is made of ceramic.

Fig. 7 shows a schematic top view of a sink insert 200, the outer edges 202 of which are circular. The sink 300 is rectangular and has rounded corners. Fig. 7, below, shows a corresponding cross-sectional view, from which it can be seen that in the edge area of the sink insert 200 there is a multiplex chipboard 204, on the surface of which a 2 mm thick stainless steel overlay of the sink 300 rests.

Fig. 8 shows a representation corresponding to Fig. 7, wherein the sink 300 is round. Here too, the edge region of the sink insert 200 is formed by a multiplex chipboard 204, on which the edge region of the stainless steel sink 300 extends.

Fig. 9 also shows a schematic top view and cross-sectional illustration of a sink insert 200 according to the invention. The sink 300 is rectangular with rounded corners. The reference number 308

-12-

marks the overflow of the sink 300. The edge area of the sink insert 200 consists, as with the previously shown sink inserts, of a multiplex chipboard 204 and the stainless steel support of the sink 300.

Fig. 10 shows a schematic top view and cross-sectional view of a sink insert 200 with a circular sink 300 and overflow 308. The outer edges 202 of the sink insert 200 are not formed by a multiplex chipboard, but by the material of the sink 300. The sink 300 and the entire sink insert 200 according to the embodiment of Fig. 10 are made of ceramic.

Fig. 11 shows a schematic top view and cross-sectional representation of a sink insert 200, which is also made of ceramic and has the sink 300 and the overflow 308. To the right and left of the sink 300, drainage grooves 306 are arranged, which lead water located next to the sink 300 back into the basin 300.

Fig. 12 shows a further embodiment in a schematic top view and cross-section of a sink insert 200 made of ceramic. The sink 300 is divided, with the smaller of the basins 300 having the overflow 308 and the residue strainer 310. In this embodiment too, it is clear that the outer edges 202 of the sink insert 200 are formed exclusively by the material (ceramic) of the sink insert 200. Additional multiplex chipboards as with stainless steel basins are not required.

Fig. 13 shows a schematic top view and cross-sectional view of a sink insert 200 with a stainless steel sink 300 and overflow 308. The outer edges 202 of the sink insert are formed here by a 35 mm thick beveled multiplex chipboard 204 and the 2 mm thick stainless steel support of the sink 300 located thereon.

-13-

Fig. 14 shows a sink insert 200 made of ceramic with overflow 308 and residue strainer 310. Around the sink 300, several drainage grooves 306 oriented radially to the drain are arranged to drain the excess water.

Fig. 15 also shows a sink insert 200 made of ceramic with drainage grooves 306. The sink 300 is divided into two areas, wherein the drain of the smaller area shown above is provided with a residue strainer 310.

Fig. 16 shows a schematic top view and cross-section of the sink according to the invention with a worktop 100 consisting of a base body 106 and a ring 108. The ring 108 has circumferential projections 112. These are received in corresponding circumferential grooves 114 of the base body 106. As can be seen from Fig. 16, below, and in particular from Fig. 17, which shows an enlarged detailed view of the ring 108 and the adjacent areas of the base body 106 and the sink insert 200, there is a groove 114 directly below the melamine coating 116 of the base body 106, into which the corresponding projection 112 of the ring 108 engages. It is clear from Fig. 17 that the projections 112 have grooves 113, which results in a particularly tight connection between the projection 112 and the corresponding groove 114. The space 118 in the area of the groove end can be filled with an adhesive filler so that there is no possibility of water or moisture penetrating into the area below the coating 116. The ring 108 is glued to the corresponding recess in the base body 106 on its outer circumference. It has the beveled edge 104 on its inner circumference.

The sink insert 200 with outer edges 202 bevelled according to the invention is inserted into the recess 102 of the worktop 100 formed by the ring 108 and is glued to it. Alternatively or additionally, a rubber ring seal or a seal using silicone can be provided here.

-14-

The ring 108 is made of PVC or any other elastic material. The base body 106 of the worktop 100 is made of a chipboard.

In summary, it can be seen that the sink according to the invention can be used to create a simple and tight connection between the sink insert and the corresponding recess in a worktop, with the additional advantage that no gaps are created between the surface of the worktop and the sink insert and that it is easily possible to have the sink insert flush with the top of the worktop or, depending on requirements, be set back from the worktop or even protrude.
