Description

Technical Field

[0001] The invention relates to a drain device, in particular an air capture drain device, and an arrangement comprising a drain device and a mounting device for a sanitary appliance according to the preambles of the independent patent claims. Background Art

[0002] Air traps (traps) are known in the prior art for various sanitary appliances, such as washbasins, showers, bathtubs, toilets, or urinals. Such air traps (more generally, traps) serve, among other things, to prevent gases from escaping from the sewage pipe into the ambient air. In particular, this serves to prevent unpleasant odors from being released into the environment of the sanitary appliance, i.e., in particular, into the ambient air.

[0003] Different embodiments of air traps and drains are known. One common form is the so-called P-type air trap and drain, in which a water receiving area is provided to prevent the passage of air between the sewer pipe and the ambient air.

[0004] Many air trap drains, including P-type air trap drains, suffer from disadvantages in configurations that require low head of liquid to be drained from sanitary appliances. In particular, continuous and immediate drainage of liquid is problematic in such configurations, as a certain static pressure must be overcome to allow the liquid to drain. However, this means that liquid accumulates to a certain level before being drained intermittently, which is undesirable, particularly in the case of washbasins, showers, and the like. Even particularly space-saving air trap drain configurations often suffer from shortcomings in terms of liquid drainage. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a drainage device, in particular an air-trapping drainage device, which overcomes the disadvantages of the prior art, allows continuous and immediate drainage of liquid, and ensures the air-trapping drainage function even when the head of the discharged liquid is low and / or the construction of the drainage device is small.

[0006] This and other objects of the invention are solved by a drainage device having the features of the independent patent claims.

[0007] The present invention therefore relates to a drainage device, in particular an air trapping drainage device, comprising an inlet opening connectable to a sanitary fixture and a drain opening connectable to a sewage pipe. Furthermore, the device comprises a sealing section disposed between the inlet opening and the drain opening. By filling the sealing section with a liquid, air is prevented from passing between the inlet opening and the drain opening.

[0008] According to the invention, it can be provided that an actuating device and a vent opening are provided, wherein in the rest position the actuating device closes the vent opening, in the actuated position the actuating device releases the vent opening, and wherein in the actuated position gas is allowed to pass between the drain opening and the vent opening.

[0009] The actuating device can therefore be in at least two mutually different positions. The switch between the rest position and the actuating position can in particular be achieved by means of a liquid flowing through the drain device.

[0010] Alternatively, it may be provided that the actuating device can be brought into the actuating position by means of a liquid flowing through the drain device.

[0011] Alternatively, it can be provided that the actuating device is configured as an actuating lever that can be pivoted about a pivot axis. The actuating lever can in particular have two lever sections that are arranged on both sides of the pivot axis.

[0012] Alternatively, the actuating device may comprise a closing element which, in the rest position, abuts against the exhaust opening and closes the exhaust opening. In particular, the closing element may be a part of a rod section of the actuating rod.

[0013] Optionally, it can be provided that the actuating device comprises an inflow section arranged at an angle. The inflow section can optionally be arranged at the end section of the actuating device or the actuating rod.

[0014] Optionally, it may be provided that the connecting pipe is provided between the inlet opening and the drain opening, and the connecting pipe includes the closed section.

[0017] The curved connecting section may be optionally arranged between each descending section and the ascending section. Preferably, each descending section and the ascending section extend substantially parallel to each other.

[0018] Optionally, it can be provided that a fastening device is provided for fastening the drain device to another component. The fastening device can be configured as a latching device or a clamping device.

[0019] Optionally, the fastening device comprises a groove into which the holding region of the other component can be inserted.

[0020] Optionally, it can be provided that the drainage device is a P-type air capture drainage device.

[0021] Optionally, it can be provided that a gas outlet opening is provided in the housing of the drain device and allows gas to pass between the environment of the drain device and a connecting pipe provided between the inlet opening and the drain opening.

[0022] Alternatively, it can be provided that the connecting pipe comprises an inlet section in the region of the inlet opening and a drain section in the region of the drain opening, the inlet section and the drain section being arranged substantially perpendicular to one another.

[0024] Optionally, it may be provided that the closed section is provided in the region of the curved connecting section between the first descending section and the ascending section.

[0025] The invention also relates to an arrangement comprising a drainage device according to the invention and a mounting arrangement for a sanitary appliance, in particular a flush-mounted cassette. The problem of low head of inflowing liquid mentioned at the outset arises in particular in flush-mounted cassettes, since these cassettes generally have a particularly compact design.

[0026] Alternatively, it can be provided that the fastening device is connected to the holding region of the mounting device. For example, the holding region can be configured as a region that can be connected to the fastening device in a form-fitting manner.

[0028] Alternatively, it may be provided that a drain pipe of the sanitary fixture is connected to the inlet opening of the drain device.

[0029] Further optional features of the invention will become apparent from the dependent claims, the drawings and the description of exemplary embodiments.

[0030] Hereinafter, the present invention is discussed in detail based on an exemplary embodiment. The exemplary embodiment is only used to illustrate the functions of a device having preferred features of the present invention and is not intended to limit the scope of protection of the patent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the attached figure:

[0032] Figure 1 is a side cross-sectional view of a drainage device according to an exemplary embodiment of the present invention;

[0033] Figure 2 is another side cross-sectional view of a drain device according to an exemplary embodiment of the present invention; and

[0034] Figure 3A cross-sectional view shows an arrangement of a drain device according to an exemplary embodiment mounted on a flush-mounted box. DETAILED DESCRIPTION

[0035] Figure 1 and Figure 2 Two side cross-sectional views of a drainage device according to an exemplary embodiment of the present invention are shown, with the corresponding cross sections being arranged substantially orthogonal to each other.

[0036] The drainage device comprises an inlet opening 1 and a drain opening 2. The inlet opening 1 is configured to be connected to a sanitary fixture, such as a wash basin. The drain opening 2 is configured to be connected to a sewage pipe or more generally to a sewage system.

[0037] A connecting pipe 12 is provided between the inlet opening 1 and the drain opening 2, and the connecting pipe 12 allows liquid to flow from the inlet opening 1 to the drain opening 2. The drainage device shown in this exemplary embodiment is designed as a P-type air-capturing drainage device. Accordingly, the connecting pipe 12 includes a first descending section 13, a second descending section 14 and an ascending section 15, and the ascending section 15 is provided between the descending sections 13 and 14. The individual sections extend substantially parallel to each other. These sections are arranged in series, i.e., continuously, and the individual sections are connected to each other by curved connecting sections. In particular, the connecting pipe 12 in this exemplary embodiment has a generally S-shaped configuration.

[0038] In this exemplary embodiment, the connecting pipe 12 includes an inlet section 18 and a drain section 19, which are arranged substantially perpendicular to each other. The inlet section 18 is arranged in the region of the inlet opening 1, while the drain section 19 is arranged in the region of the drain opening 2. In this exemplary embodiment, the closing section 3, the descending sections 13 and 14, and the ascending section 15 are arranged between the inlet section 18 and the drain section 19.

[0039] exist Figure 1 and Figure 2 In the intended use of the illustrated air trapping drain device, gases should be prevented from entering the ambient air of the sanitary fixture connected to the inlet opening 1 from the drain pipe connected to the drain opening 2. This serves the purpose, in particular, of preventing the release of unpleasant odors from the sewage system. Therefore, the drain device includes a closing section 3, which, in this exemplary embodiment, is arranged at the transition from the first descending section 13 to the ascending section 15. The closing section 3 can be filled with a liquid, in particular a liquid discharged from the sanitary fixture, and once the filling level of the closing section 3 is sufficient, the liquid prevents gases from passing from the drain opening 2 to the inlet opening 1.

[0040] Due to the positioning of the inlet opening 1, the incoming liquid has a low head and therefore a low flow pressure. In order to enable immediate and continuous drainage of the liquid from the sanitary fixture, the drain device according to the present invention of this exemplary embodiment includes an actuating device 4 configured as an actuating lever 7. The actuating lever 7 is pivotally mounted about a pivot axis 6 and can be assumed at least in a rest position and an actuated position.

[0041] When no liquid flows through the drain device, the actuating lever 7 is in the rest position. In the rest position, the closing element 16 of the actuating lever 7 closes the vent opening 5 in the housing 17 of the drain device. The vent opening 5 provides a gas-permeable connection between the interior of the housing 17 (i.e. the connecting pipe 12) and the environment of the drain device.

[0042] When liquid flows through the drain, the actuating lever 7 is in the actuated position. Due to the pivoting movement of the actuating lever 7, the closing element 16 releases the vent opening 5, thereby allowing gas to pass between the drain opening 2 and the vent opening 5, and thus to the surrounding air of the drain. This results in a pressure balance between the interior of the drain and the surrounding air, thereby ensuring continuous drainage of the liquid.

[0043] The exhaust opening 5 serves, among other things, as a pressure equalizer between the connecting pipe 12 and the ambient air.

[0044] In order to improve the actuation of the actuating lever 7, in this exemplary embodiment the brake lever 7 has an angled inflow section 8. The inflow section 8 has a widened cross section and is arranged at one end of the actuating lever.

[0045] Once the flow of liquid through the drain device stops, for example, after the supply of liquid to the sanitary fixture is stopped, the actuating lever moves back to the rest position in the absence of flow pressure from the liquid, thereby preventing gas from passing through the exhaust opening 5 and thus preventing unpleasant odors from forming in the ambient air. When the liquid flow is resumed, the actuating lever 7 returns to the actuated position as described above.

[0046] Figure 1 and Figure 2 The drain device shown also has a fastening device 9. The fastening device 9 is arranged on the housing 17 of the drain device and is used to fasten the drain device to another component, such as a mounting device. In particular, the fastening device 9 according to this exemplary embodiment is used to fasten the drain device to a flush-mounted box.

[0047] Figure 3A cross-sectional view shows the arrangement of a drain device according to an exemplary embodiment, mounted on a flush-mounted box. The drain device is attached to the wall of a flush-mounted box 10 via fastening means 9 and has an inlet opening 1, a drain opening 2, and a connecting pipe 12 arranged between the inlet opening 1 and the drain opening 2. The wall has a retaining area 11 that can be inserted into a recess in the fastening means 9. This facilitates the installation of the drain device according to the present invention.

[0048] To simplify the explanation, Figure 1 and 2 Some of the components shown in Figure 3 Not shown.

[0049] Although the exemplary embodiments described herein show a P-type air trap and drain, the present invention is also applicable to other air trap and drain configurations, such as a bottle-type air trap and drain, a cup-type air trap and drain, and the like.
