Definitions

  • the present invention relates to a basin with a floor drain with a drain opening for liquids arranged in the bottom surface of the basin and with a closure element for selectively closing or opening the drain opening, as well as a kitchen sink with such a basin according to the preambles of the independent patent claims.
  • a generic basin with a floor drain is known in which the closure element can be positioned in a first position, a second position and a third position by means of associated actuating means by essentially vertical displacement.
  • the second position is arranged between the first and third positions and the closure element in the first position is in sealing contact with a valve seat surface surrounding the drain opening and thereby closes the drain opening in a liquid-tight manner.
  • the closure element opens the drain opening.
  • the closure element has a cover on its upper side which, when the closure element is arranged in the second position, is arranged essentially flush with the floor surface of the basin in a recess in the basin floor above the drain opening and, with the boundaries of the recess, forms a drainage gap around the cover to connect the basin to the drain opening.
  • the cover In the first position the cover is arranged sunk in the recess and in the third position it protrudes above the floor surface of the basin so that it can be grasped by hand and the closure element can thus be removed from the basin.
  • the previously described state-of-the-art pool has the disadvantage that the position of the panel in relation to the floor surface of the basin and with regard to the limits of the recess in the basin floor in the second position depends on the vertical positioning accuracy of the actuating means and the radial guidance precision of the closure element guide, which makes it difficult or expensive to achieve a high-quality appearance in the second position with a panel that is exactly flush with the floor and a uniformly wide, circumferential drainage gap.
  • the known basin also has the disadvantage that the closure element can be moved from the open second position to the closed first position by exerting force on the panel, which can be problematic if it is inadvertently done.
  • the task is therefore to provide a technical solution which does not have the previously mentioned disadvantages of the state of the art or at least partially avoids them.
  • a first aspect of the invention relates to a basin with a floor drain, preferably a kitchen sink.
  • a drain opening for liquids is arranged in the bottom surface of the basin, which can be optionally closed or opened with a closure element, preferably with a closure plug.
  • the closure element can be positioned in a first position, a second position and a third position by means of associated actuating means by essentially vertical displacement, the second position being arranged between the first and the third position.
  • the closure element In the first position, the closure element is in sealing contact with a valve seat surface surrounding the drain opening and thereby closes the drain opening in a liquid-tight manner.
  • the closure element In the second and third positions, the closure element opens the drain opening.
  • the basin further comprises a panel which, when the closure element is arranged in the first and second positions, is arranged essentially flush with the bottom surface of the basin in a recess in the basin floor above the drain opening and, together with the boundaries of the recess, forms a drain gap around the panel for connecting the basin to the drain opening.
  • the panel When the closure element is arranged in the first and second positions, the panel is supported by a support surface within the recess which is not formed by the closure element.
  • the closure element When the closure element is arranged in the third position, the panel is supported by the closure element and protrudes beyond the bottom surface of the basin so that it can be grasped by hand and removed from the basin.
  • the design according to the invention makes it possible to create basins with floor drains in which the drain opening is covered with a precisely positioned cover flush with the floor both when the drain valve is closed and when it is open.
  • This cover cannot exert any closing forces on the closure element of the drain valve, but can be brought into a removal position with the latter, in which it can be grasped by hand and removed from the basin. Accordingly, a high-quality appearance can be ensured in the long term with a cover exactly flush with the floor and operational reliability can be increased.
  • the closure element and the cover form a coherent unit, so that the closure element can be removed from the basin in the third position by grasping the cover.
  • the closure element and the cover do not form a coherent unit, so that the cover can be removed from the basin in the third position while the closure element remains.
  • the locking element In the third position, after the cover has been removed, the locking element extends beyond the bottom surface of the basin and can also be grasped by hand and removed from the basin.
  • the basin is designed in such a way that the closure element in the second position opens the drain opening with a first drain cross-section and in the third position opens the drain opening with a second drain cross-section which is larger than the first drain cross-section.
  • the closure element comprises or forms a drain strainer, preferably in the form of a strainer basket, and is designed in such a way that when the closure element is arranged in the second position, any liquids flowing into the drain opening must pass through the drain strainer. This can ensure that larger dirt particles, which could clog the drain lines downstream of the drain opening, are retained.
  • closure element is guided over the drain strainer and/or positioned radially with respect to the drain opening. This enables particularly compact designs.
  • the boundaries of the drain opening in the bottom surface of the basin and the valve seat surface are formed by a drain arrangement made up of components that are designed separately from the actual basin floor. It comprises a first component that is placed on the inside of the basin in areas surrounding the drain opening. of the pool floor and a second component which rests on the underside of the pool on the areas of the pool floor surrounding the drain opening.
  • the first component is sealed against the pool floor, e.g. by means of a seal such as an O-ring or an elastically hardening sealing compound.
  • the first component and the second component are connected to one another, preferably in a form-fitting manner, in such a way that the areas of the pool floor on which they rest are clamped between them. It is not necessary for the support surfaces of the first component and the second component resting on the areas of the pool floor to be directly opposite one another. These support surfaces can also rest at different points on the top and bottom of the pool floor.
  • the connection between the first component and the second component is realized outside the drain opening.
  • This design makes it possible to provide a drain cross-section with a maximum cross-sectional area in a cost-effective manner.
  • the drain arrangement is advantageously designed in such a way that the drain opening formed by it has a single, essentially unobstructed drain cross-section. This can effectively prevent blockages caused by bridging of dirt particles contained in the wastewater.
  • connection between the first component and the second component of the drain arrangement is preferably implemented in the area of the peripheral boundaries of the drain opening delimited by this and/or in the immediate vicinity of the pool floor, advantageously in the immediate vicinity of the areas of the pool floor on which they rest.
  • Such a design of the connection between the first and second components enables particularly compact and robust drain arrangements.
  • connection between the first component and the second component of the drain arrangement as a threaded connection enveloping the drain opening.
  • the boundaries of the drain opening formed by the drain arrangement have guides for guiding the closure element during its movement between the first, second and third positions or form such guides. This makes it possible to guide the closure element within the drain opening without significantly affecting its cross-section.
  • the boundaries of the drain opening formed by the drain arrangement have radial positioning means for a rotational positioning of the closure element with respect to the drain opening, based on the longitudinal axis of the drain opening, or form such positioning means.
  • radial positioning means for a rotational positioning of the closure element with respect to the drain opening, based on the longitudinal axis of the drain opening, or form such positioning means.
  • the basin according to the invention comprises muscle-power-operated actuating means or external energy-operated actuating means, for example electrically operated actuating means, with which the closure element can be moved from the first position into the second position and into the third position.
  • the actuating means are arranged in a drain housing attached to the drain arrangement. This enables relatively compact solutions and simple installation of the actuating devices.
  • the closure element comprises a drain sieve
  • the actuating means are designed in such a way that actuating forces for moving the closure element from the first to the second position and preferably also to the third position are transmitted to the sieve element.
  • the closure element is carried by the sieve element.
  • the actuating forces are transmitted to the sieve element at at least two points on the sieve element that are spaced apart from one another. This latter design allows the guides for guiding the closure element during movement from the first to the second position to be kept very short, since this type of force introduction can effectively prevent the closure element from tilting.
  • a second aspect of the invention relates to a kitchen sink with a basin according to the first aspect of the invention.
  • the advantages of the invention are particularly evident in such applications.
  • FIGS. 1 , 2 and 3 show vertical sections through the floor drain 1 of a basin 15 according to the invention of a kitchen sink made of stainless steel, once in the open basic position (second position according to the claim, Fig.1 ), once in the closed position (demanding first position, Fig.2 ) and once in the open removal or cleaning position (demanding third position, Fig.3 ).

  • the inlet ring 6 forms the boundaries of the drain opening 3 in the bottom surface 2 of the basin 15.
  • a seal 8 is arranged between the inlet ring 6 and the bottom surface 2 of the basin 15, which prevents liquid from running off in the adjoining gap formed between them.
