DETAILED DESCRIPTION
[0024] The present invention is directed to water drainage devices and more particularly to water drainage devices for showers and shower floor elements.
[0025] The ensuing description provides exemplary embodiment(s) only, and is not intended to limit the scope, applicability or configuration of the disclosure.
Rather, the ensuing description of the exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing an exemplary embodiment. It being understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope as set forth in the appended claims.
[0026] This object is achieved by a water flow device of the mentioned in the preamble of claim 1, of the type wherein:
- the bell member is a hollow body comprising an elongated, rectilinear apex region, two elongate side panels and also opposite to the two narrow sides of the hollow body more side walls;
- the inner chamber formed in a top view of a bottom of the housing enclosed by a circumferential first barrier wall and completely excluded from the outer chamber forming the passage area for the discharge nozzle;
- between the inner chamber and the outer chamber, is arranged an intermediate chamber when used the bell element which is entirely, except for in the passage area for drain connection , enclosed in a plan view of the bottom of one formed by the side walls of the second barrier wall so that the chambers are formed by a ring lying around each barrier walls and the housing wall ; and - wherein the outer chamber is separated by the second blocking wall of the central chamber and the medium chamber by the first blocking wall of the inner chamber and the flow direction of the waste water from the outer chamber to the central chamber, from there to the inner chamber and is directed there to the discharge nozzle.
[0027] The barrier wall of the bell element has a recess, so that the bell element can be placed over the interior chamber and extending from the inner chamber the outlet fitting. It is provided that sealingly encloses the recess in the assembled state the outlet flow pipe. This is particularly important for compliance with relevant standards, such as DIN EN
1253/274, and subsequently the building code approval for the drainage device important.
Accordingly, the recess may be surrounded by a groove into which a sealing element is inserted.
Preferably, the recess, and thus the groove is U-shaped. The cover can be locked against floating by clicking or locking means or other securing means.
[0028] The flow- technical considerations have shown that it is particularly advantageous if the outer chamber, a first surface, and the middle chamber has a bottom edge at the height of the barrier wall , a second surface, the area ratio is within a range of 0.5 to 0.8 , preferably between 0 63 and is 0.69 . It has been found that an advantageous locking height corresponding to a distance between the upper edge of the barrier wall and the lower edge, should be at least 38 mm. These measures will help to very flat construction of water drainage device while still allowing sufficient drainage capacity of the overall system.
[0029] It is also particularly advantageous for the ultra-flat design, when the drain pipe the drainage device is within an outline of a base plate of the water outlet device. For this purpose may be provided for receiving the discharge tube on the underside of the base plate a groove-like recess.
[0030] It is also particularly advantageous when the water flow device, except the gutter cover and the bell member, on whose bottom embedded in an elongated through hole of the said base plate and fixed there. The elongated opening of the base plate has dimensions that exceed those of the tray cover slightly, so that it is manufactured by a gap extending around the trough cover. A gap- less design is also possible, if appropriate perforations, such as holes, slits or mesh- shaped structures are placed in the water flow on the tray cover. The channel cover itself may be formed from a lattice or honeycomb structure, for example expanded metal.
[0031] Beneficial for the water drain it is when the subsequent directly to the drainage spigot inner chamber having a bottom, on both sides which has a drain connection -cut the slope or trough- shaped. Here, the bottom of the inner chamber can be lifted from the remaining bottom of the housing.
[0032] The passage of the internal compartment to the outlet stub can also be funnel-shaped.
[0033] To the outlet flow pipe, a circular or oval-shaped flow tube or a square discharge pipe can be connected. Preferably, the outlet flow pipe is a rectangular cross-section, which can be implemented easily with the square drain pipe connection.
[0034] The water drainage apparatus may comprise a channel module with the water outlet opening and a flow module with a water inlet opening.
[0035] The water drainage device includes an expiration module that contains the trap system , comprising the above mentioned case with the chambers and the bell member, [0036] The water outlet opening of the channel module is rectangular or oval, [0037] The water inlet opening of the trap system has for each water tap opening a compatible contour.
[0038] Between the channel module and the flow module, a connection is provided, which may be an adhesive, click, snap or screw connection.
[0039] The channel module and the outlet module may comprise contact surfaces and structural elements, said structural elements are designed so that they form a labyrinth seal according to the preparation of the compound.
[0040] It is not excluded that the channel module with the flow module, the exception of the bell element in a piece of material, such as thermoplastic plastics manufactured.
