Description

[0001] Drainage system and sink with drainage system

[0002] The invention relates to a drain arrangement for a sink, comprising a base body with an inlet and an outlet, as well as a valve for closing and / or releasing the inlet.

[0003] The invention also relates to a sink with a drain arrangement.

[0004] Sink drains come in a variety of forms. They typically include an inlet into which water flows from the sink and an outlet for draining the water away, for example, into a sewer. The inlet can be closed by a valve—such as a strainer basket—to retain the water in the sink. This valve can be operated manually by pulling, turning, and / or tilting it, or it can be remotely controlled, for example, by pressing a button.

[0005] The connection for manual or remote control operation of the valve is determined by a base unit of the drain assembly. If the drain assembly is to be converted from manual operation to operation via a remote control device, or if a different type of remote control device is to be used, a different base unit must be installed in the sink, which is a complex process.

[0006] A drainage arrangement is known from JP 2008-063840 A in which the valve can be actuated by an electromagnet. The valve comprises a permanent magnet that can be moved by an electromagnet, the electromagnet being arranged on the underside of the drainage arrangement. The electromagnet can be switched on and off by an operating element.

[0007] One disadvantage is that the drain assembly cannot be easily used with an alternative remote control device. Furthermore, the drain assembly's valve cannot be easily operated manually.

[0008] An object of the present invention is therefore to provide a drain arrangement and a sink with a drain arrangement in which different types of remote control devices can be arranged in a simple manner and in which the remote control device can be changed in a simple and cost-effective manner.

[0009] Another object of the present invention is to provide an alternative drainage arrangement and an alternative sink with a drainage arrangement.

[0010] In one embodiment, the present invention solves the aforementioned problems in a drain arrangement for a sink, comprising a one- and / or multi-part base body with an inlet and an outlet, as well as a valve for closing and / or opening the inlet, by providing at least one open or openable opening spaced apart from the inlet and outlet in the base body, in which a drain exchange element, particularly with a fixed valve, can be detachably fixed, wherein at least one sealing element can be arranged on the drain exchange element and / or the base body, so that the drain exchange element fluidly closes the opening in the arranged state.

[0011] In one embodiment, the present invention solves the aforementioned problems in a sink with a drain arrangement according to one of claims 1 to 17.

[0012] One of the advantages achieved is that various drain exchange elements can be easily arranged within the drain assembly, allowing, for example, different valve actuation configurations. Another advantage is that the drain assembly's base body can be easily cleaned. The term "drain exchange element" is to be understood in the broadest sense and refers, particularly in the claims and preferably in the description, to functional elements of the drain assembly that can be arranged within the opening, such as plugs, seals, valve actuation elements, sensors, or drive units.

[0013] The term "sealing element" is to be understood in the broadest sense and refers, particularly in the claims and preferably in the description, specifically to an object that can fluidically close the opening. For example, the sealing element can comprise a soft and / or elastic material, in particular rubber, that can seal the opening. It is also conceivable that the sealing element comprises a hard material that can be inserted into the opening by means of an interference fit and thus fluidly seals the opening. Furthermore, it is conceivable that the sealing effect is achieved by a suitable material pairing of the opening and the drain exchange element.

[0014] The phrase “provision of a breakthrough” is to be understood in the broadest sense and refers, particularly in the claims, preferably in the description, not only to a breakthrough that has already been formed, but also to a breakthrough that is exposed, for example, by cutting open a plastic body in the area of ​​the provided breakthrough.

[0015] The term “openable breakthrough” is to be understood in the broadest sense and refers, particularly in the claims, preferably in the description, to a breakthrough that is initially closed, which is exposed, for example, by cutting open a plastic body in the area of ​​the intended breakthrough during first use.

[0016] The term "open opening" is to be understood in the broadest sense and refers, particularly in the claims, preferably in the description, to an already formed opening. Further features, advantages, and further embodiments of the invention are described below or become apparent therein. According to an advantageous embodiment of the invention, the drain replacement element comprises a valve actuating element with which the valve can be opened and / or closed, and / or a sink overflow element, and / or a connection element for a wastewater supply, in particular in the form of a hose connection fitting. Since the valve actuating element is arranged in the opening, it can be easily removed and reattached. In this way, different valve actuating elements can be arranged in the drain assembly as needed or according to customer requirements.One advantage of this is that the valve can be remotely controlled in various ways. Another advantage is that, for example, a sink overflow and / or a drain hose, such as from a washing machine, a dishwasher, and / or a water treatment unit, as well as a sensor device with one or more sensors, can be directly attached to the drain assembly.

[0017] According to a further advantageous embodiment of the invention, the valve actuating element comprises a lever element, in particular a lever, a rotary disc, a gear, and / or an electromagnetic connection, which extends through the opening. The lever element can be actuated, for example, by a remote control device and, upon actuation, push or pull the valve into an open or closed position. Since the lever element extends through the opening, it can be easily arranged in the drain assembly. The lever element can, for example, be an elongated rod that is rotatable about an axis. By selecting a suitable length for the lever element and a suitable axis of rotation, sufficient force can be provided for the, in particular mechanical, actuation of the valve.One advantage of this is that the lever element can easily operate the valve.

[0018] According to a further advantageous embodiment of the invention, the lever element is movable between a closed position, in which the lever element is located further away from the inlet, and an open position, in which the lever element is located closer to the inlet. In other words, the lever element can be moved towards and away from the inlet. This direction of movement can correspond to the direction of movement of the valve when opening and / or closing it. For example, when moving towards the inlet, the lever element can push the valve upwards, rotate the valve, and / or tilt it to the side, thus releasing the inlet. It is also conceivable that other positions are provided, such as a cleaning position and / or a half-open position. An advantage of this is that movement of the lever element can easily be used to move the valve.

[0019] According to a further advantageous embodiment of the invention, the valve actuating element comprises a Bowden cable. The Bowden cable can be connected to the valve actuating element in such a way that the valve actuating element is actuated when the Bowden cable is pulled and / or pushed. An advantage of this is that it enables cost-effective remote control of the valve actuating element.

[0020] According to a further advantageous embodiment of the invention, the valve actuating element comprises an electric drive unit. For example, the lever element can be moved by the electric drive unit. The drive unit can, in particular, comprise an electric motor and be arranged within the opening and / or fixed to an outer wall of the base body. It is conceivable that the electric drive unit is arranged at a distance from the valve actuating element and can actuate the valve actuating element by means of an action element. An advantage of this is that simple actuation of the valve is made possible.

[0021] According to a further advantageous embodiment of the invention, the valve actuating element comprises a communication interface for wireless and / or wired communication with a receiving device. The communication interface can communicate with the receiving device, for example, via Bluetooth or Wi-Fi. It is also conceivable that the communication interface includes a signal line through which information can be sent to and / or from the communication interface. In particular, control signals for an electric drive device can be transmitted via the communication interface. Furthermore, it is conceivable that the communication device can communicate with a sensor, for example, a gesture sensor.In particular, a motion sensor can detect a user's movement or gesture and send a signal to the communication unit, which in turn can provide a control signal for the valve. The gesture sensor could be a foot gesture sensor, capable of detecting a user's foot gesture and / or movement. One advantage of this is that it simplifies remote control of the valve unit.

[0022] According to a further advantageous embodiment of the invention, the communication interface is configured for communication with an app on a user device. Using the app, a user can, for example, query information about the status of the drainage system or provide control signals to the communication interface. The user device can be, for example, a smartphone, an external device, a mixer tap and / or a faucet and / or a water treatment system. In this way, a user can be provided with more information and / or setting options for the drainage system. It is also conceivable that data, such as data from a humidity sensor, can be transmitted via the communication interface of the drainage system so that the valve of the drainage system can be actuated based on this data, for example, to provide overflow protection.It is also conceivable that the data could be used to enable level detection and / or a level display for a user. Similarly, temperature, water quality, and / or flow rate could be transmitted to detect blockages or similar issues.

[0023] According to a further advantageous embodiment of the invention, the base body is provided with at least one projection, recess, hook, eyelet, or seat for arranging the drive unit, the communication interface, and / or a locking device. In particular, several projections, hooks, eyelets, or seats can be provided, which can be injection-molded onto the base body, for example. In particular, the projections, hooks, eyelets, and / or seats can be formed integrally with the base body. An advantage of this is that the drive unit, the communication unit, and / or the locking device can be easily arranged on the base body.

[0024] According to a further advantageous embodiment of the invention, the drain replacement element can be secured in the opening by means of a force-fit connection, in particular a friction and / or magnetic connection, by means of a positive fit, in particular a clip connection, a bayonet fitting or a snap-fit ​​connection, and / or by means of a material bond, in particular an adhesive. An advantage of this is that the drain replacement element can be easily replaced and / or securely positioned in the opening.

[0025] According to a further advantageous embodiment of the invention, the at least one sealing element is an O-ring, a two-component seal, a press-fit element, and / or an X-ring. An advantage of this is that one or more seals can be provided in a cost-effective manner. Another advantage is that a friction-fit connection between the drain exchange element and the passage can be simultaneously enabled.

[0026] According to a further advantageous embodiment of the invention, an axis along the inlet and an axis along the at least one opening are arranged essentially perpendicular to each other. In other words, the opening is arranged on a side wall of the base body so that wastewater flowing through the inlet and into the outlet is not directed onto the opening. It is also conceivable that the opening is arranged eccentrically. Furthermore, it is conceivable that the sealing element is arranged to be tiltable and / or rotatable. An advantage of this is that the probability of wastewater leakage through the opening is reduced.

[0027] According to a further advantageous embodiment of the invention, the at least one opening and the outlet are arranged on opposite sides relative to the inlet, in particular parallel to each other. An advantage of this is that wastewater flowing from the drain assembly is directed away from the opening, thus reducing the likelihood of wastewater leakage through the opening. It is also conceivable that the opening is arranged on the underside of the drain assembly. An advantage of this is that the valve can be easily operated through the opening.

[0028] According to a further advantageous embodiment of the invention, several openings, in particular three openings, are arranged. This increases the flexibility with regard to the use of the flow arrangement by different components.

[0029] According to a further advantageous embodiment of the invention, an opening is arranged in the extension of the central axis of the outlet, and wherein at least two openings are arranged symmetrically to the central axis, in particular on a common axis, and in particular wherein the at least two openings are arranged perpendicular to the central axis of the outlet. This increases, firstly, the flexibility with regard to the use of the drain arrangement by different components, and secondly, provides good accessibility to the openings.

[0030] According to a further advantageous embodiment of the invention, at least one opening, and in particular several openings, is arranged at an angle of more than 0 degrees and less than 90 degrees, preferably 30 degrees, 45 degrees, 60 degrees, or 75 degrees, relative to the central axis of the outlet. The advantage of this is a high degree of flexibility for the arrangement of drain exchange elements depending on their space requirements and within a base cabinet.

[0031] According to a further advantageous embodiment of the invention, the valve actuating element can be actuated by means of a rotary knob, a push button, a pull knob, a sensor signal, and / or an electronic control element. The rotary knob, push button, and / or pull knob can be used, in particular, to mechanically actuate the valve actuating element, while the electronic control element can be used, in particular, to actuate an electrical drive unit for the valve actuating element. An advantage of this is that the valve can be actuated in a simple manner. Further important features and advantages of the invention will become apparent from the dependent claims, the drawings, and the accompanying description of the figures with reference to the drawings.

[0032] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0033] Preferred embodiments and configurations of the present invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components or elements.

[0034] This is shown in schematic form

[0035] Figure 1 shows a flow arrangement according to an embodiment of the present invention;

[0036] Figure 2a shows a flow arrangement according to an embodiment of the present invention;

[0037] Figure 2b shows the sequence arrangement according to Figure 2a with the Bowden cable inserted;

[0038] Figure 3 shows a flow arrangement according to an embodiment of the present invention;

[0039] Figure 4 shows a sink according to an embodiment of the present invention;

[0040] Figure 5 shows a flow arrangement according to an embodiment of the present invention; and

[0041] Figure 6 shows a flow arrangement according to one embodiment of the present invention. Figure 1 shows a flow arrangement according to one embodiment of the present invention.

[0042] The drainage arrangement 1 comprises a base body 7 with an inlet 2 and an outlet 3. The inlet 2 is frustoconical, tapering towards the outlet 3. The outlet 3 is cylindrical and can be connected to a drain pipe (not shown). It is also conceivable that the outlet 3 is oval and / or rectangular. A guide 4 for a valve 5 is arranged at the inlet 2. Within the guide 4, the valve 5, for example in the form of a plug and / or a strainer basket, can be moved up and down to open or close the inlet 2. In particular, a seal can be arranged on the valve 5. Specifically, the valve 5 can be moved from an open position to a closed position and from the closed position to the open position, with the open position shown in Figure 1.A locking device (not shown) can be arranged on the valve 5 and / or in the guide 4, with which the valve 5 can be held in the open and / or closed position.

[0043] In the operation of the drainage arrangement 1, wastewater can flow through the inlet 2 and into the outlet 3. The water is deflected by approximately 90° because the inlet 2 and the outlet 3 are arranged essentially perpendicular to each other. In other words, the central axis 9a of the inlet 2 and the central axis 9b of the outlet 3 are perpendicular to each other. It is also conceivable that the outlet extends along the central axis 9a of the inlet 2.

[0044] At a distal end 6 facing away from the outlet 3, an opening 8 is provided in the base body 7. The opening 8 is designed in the form of a cylindrical opening, with extensions 10a, 10b provided on the opening 8, which extend towards and / or away from the outlet 3. In particular, the extensions 10a, 10b are formed parallel to a maximum extension direction of the base body 7. To prevent wastewater from flowing through the opening 8, a drain exchange element 11 is provided. The drain exchange element 11 according to Figure 1 is designed as a plug which has a cylindrical closure body 12 and a handle 13.A sealing element 14, here in the form of an O-ring, is formed on the cylindrical closure body 12. The cylindrical closure body 12 has approximately the same cross-section as the opening 8, so that in the arranged state of the drain replacement element 11 in the opening 8, the opening 8 is fluidically closed. It is also conceivable that the sealing element 14 is arranged on the handle 13 and / or that the sealing element 14 is formed by the cylindrical closure body 12, whereby a sealing effect is achieved by a suitable material pairing of the cylindrical closure body 12 and the opening 8.

[0045] In Figure 1, the central axis 9c of the flow exchange element 11 corresponds to the central axis 9b of the outlet 3. It is also conceivable that the central axis 9c of the flow exchange element is arranged parallel to the central axis 9b of the outlet 3. In particular, the central axis 9c of the flow exchange element 11 is essentially perpendicular to the central axis 9a of the inlet 2. This means that the opening 8 is not located on a base 15 of the main body 7, but rather on a side wall 16 of the main body 7. Thus, the opening 8 is not located in the direct flow path of the wastewater when it flows from the inlet 2 to the outlet 3. It is also conceivable that the opening 8 is located at the outlet 3.

[0046] It is conceivable that during the manufacture of the drainage assembly 1, the opening 8 is initially closed. For example, the drainage assembly 1 can be manufactured by injection molding, whereby the opening 8 is provided with a cap (not shown) during the injection molding process, so that it is initially closed. If a user wishes to use the opening 8, for example to install a Bowden cable, they can open the closed opening 8 by sawing, drilling, breaking, or cutting off the cap and then close it with a suitable drainage replacement element 11. The drainage assembly according to Figure 1 is particularly suitable for providing a valve 5 that can be manually operated by a user.

[0047] Figures 2a and 2b show a process arrangement according to an embodiment of the present invention.

[0048] The sequence arrangement 1 according to Figure 2a essentially corresponds to the sequence arrangement 1 according to Figure 1. In contrast to the sequence arrangement 1 according to Figure

[0049] 1 The drainage arrangement 1 according to figure 2a comprises a drainage exchange element 11 in the form of a Bowden cable with a valve actuating element 17' comprising a lever element 17.

[0050] Analogous to the plug 11 according to Figure 1, the Bowden cable 11 according to Figure 1 comprises

[0051] 2 a closure body 12 with a sealing element 14. Thus, the Bowden cable 11 according to Figure 2 can also be inserted into the opening 8 – in particular as a complete element – ​​and close the opening 8. In particular, the plug 11 according to Figure 1 can be removed from the opening 8 in the assembled state of the valve 5 and replaced by a Bowden cable 11.

[0052] The Bowden cable 11 comprises a guide 18 and a metal wire 19, which is fixed to the lever element 17. The lever element 17 is rod-shaped and rotatably mounted about a pivot axis 28. By applying pressure and / or tension to the metal wire 19, a tip 20 of the lever element 17 can be raised and / or lowered. When the Bowden cable 11 is arranged in the opening 8, the tip 20 of the lever element 17 is located below the guide 4, so that when the tip 20 of the lever element 17 is moved, the valve 5 can be raised and / or lowered, and thus opened or closed. Such an arrangement with the Bowden cable 11 inserted and the tip 20 raised is shown in Figure 2b.

[0053] The metal wire 19 of the Bowden cable 11 can be connected to a control element (not shown), for example, a push button, a pull knob, and / or a rotary knob. In another embodiment, not shown, instead of the Bowden cable with a valve actuating element 17' comprising a lever element 17, the Bowden cable as a mechanical component can be replaced by an electrical component with an electric actuator. The actuator can be connected to an electronic control element, for example, a button, gesture control, or app connectivity.

[0054] Figure 3 shows a further flow arrangement according to an embodiment of the present invention.

[0055] The flow arrangement 1 according to Figure 3 essentially corresponds to the flow arrangement 1 according to Figure 2a. In contrast to the flow arrangement 1 according to Figure 2a, the flow arrangement 1 according to Figure 3 includes a flow exchange element 11 in the form of an electric drive unit.

[0056] Analogous to the Bowden cable 11 according to Figure 2a, the electric drive unit 11 according to Figure 3 comprises a valve actuating element 17' including a lever element 17. In contrast to the Bowden cable 11 according to Figure 2a, the lever element 17 according to Figure 3 can be moved by an electric drive unit 21. The drive unit 21 can move the lever element 17 up and / or down, similar to the metal wire 19 of the Bowden cable 11 according to Figure 2a, in order to actuate the valve 5.

[0057] The drive unit 21 can receive a command to actuate the valve 5, for example, via a communication interface 22. This interface can communicate with a receiving device, such as an app or an electronic control element (not shown), and thus receive a command to actuate the valve 5. It is also conceivable that data about the use of the valve 5 is made available to the terminal device via the communication interface 22. Furthermore, it is conceivable that a sensor 23 is provided and that the command to actuate the valve 5 is given depending on signals from the sensor 23. For example, the sensor 23 could be a motion sensor, so that the valve 5 is actuated when an object moves and / or a user gestures near the sensor 23.It is also conceivable that the communication interface 22 receives information about a possible overflow of a sink and, as a safety measure, sends a command to open the valve 5 to the drive unit 21.

[0058] The drive unit 11 has a hook 24 which can engage in an eyelet 25 on the base body 7, thus enabling the drive unit 11 to be fixed to the base body 7. It is also conceivable that a first magnet 26 is arranged on the closure body 12, which can interact with a corresponding second magnet 27 arranged on the extension 10a to secure the drive unit 11 in the opening 8. The drive unit 11 can be removed from the opening 8, for example, to clean the base body 7 through the opening 8.

[0059] Figure 4 shows a sink according to an embodiment of the present invention.

[0060] The sink 30 is designed in the form of a basin 31. A drain assembly 1, in particular according to one of Figures 1 to 3, is arranged at the bottom of the basin 31. The valve 5 closes an inlet 2 of the drain assembly 1, so that water in the basin 31 cannot flow into the inlet 2.

[0061] Figure 5 shows a flow arrangement according to an embodiment of the present invention.

[0062] Figure 5 essentially shows a drain arrangement 1 according to Figure 1. In contrast to the drain arrangement 1 according to Figure 1, the drain arrangement 1 according to Figure 5 has three openings 8, 8a, 8b. The first opening 8 is arranged in line with the central axis 9b of the outlet 3, with central axis 9c. The two other openings 8a, 8b lie in the same plane and opposite each other, that is, with their central axes 9d, 9e perpendicular to the axis 9b of the outlet 3. This results in a "cruciform" arrangement of the outlet 3 and the three openings 8, 8a, 8b. For connecting drain exchange elements 11, 11a, 11b, the openings 8, 8a, 8b have corresponding extensions 10b, 10c, 10d. For example, a valve actuating element 17', as described in Figure 1, can be arranged in the opening 8.For example, a sink overflow element 11a can be installed in opening 8a, and a hose connection fitting 11b for a wastewater hose from a dishwasher or washing machine, or for draining a water treatment system, such as a drinking water system, can be installed in opening 8b. Another possibility is to install a sensor in one or more of openings 8, 8a, 8b for determining the water temperature or quality, or for determining the flow rate, or similar parameters.

[0063] Figure 6 shows a flow arrangement according to an embodiment of the present invention.

[0064] Figure 6 essentially shows a flow arrangement 1 according to Figure 1. In contrast to the flow arrangement 1 according to Figure 1, in the flow arrangement 1 according to Figure 6 the central axis 9c of the opening 8 is rotated relative to the central axis 9b by an angle 29 of more than 0 degrees and less than 90 degrees, in this case by approximately 45 degrees.

[0065] In summary, at least one embodiment of the present invention may have at least one of the following features and / or provide at least one of the following advantages:

[0066] - Easy and non-destructive replacement of various valve actuators.

[0067] - Just one basic body for various drain replacement elements.

[0068] - Universal interface.

[0069] - Manual, mechanical or electrical valve actuation possible.

[0070] - The valve actuator can be replaced without disassembling the valve.

[0071] - Easy cleaning of the drainage system.
