Definitions

  • the present invention relates to a water drain siphon device, in particular for floor showers and shower trays .
  • these variously shaped devices generally comprise a siphon portion, which typically consists of a conveniently folded tube or is obtained within a containing case which accommodates conveniently arranged partitions.
  • the siphon portion defines a water seal between ' the environment where the device is installed and the draining tube to which the device is connected.
  • Water seal commonly means a conduit portion shaped so as to define a water stagnation zone which is interposed between conduit lengths placed upstream and downstream of the water seal, and completely obstructs the passage section of the conduit to prevent the air from passing, thus excluding backflows and odor return towards the users .
  • devices of this type to be fully effective, they should have certain constructional features and certain dimensions, which however make them relatively cumbersome, in general, especially along their height (vertical direction) , and/or complex to be manufactured and installed.
  • drain device having a water seal is shown in DEl02006058259Al, having a generally flattened shape and being thus appropriate for replacing the traditional siphons in which the tube is shaped to display sharp curves.
  • the present invention relates to a water drain siphon device, in particular for floor showers and shower trays, as defined in the appended claim 1.
  • the water drain siphon device in accordance with the invention is highly simple and cost-effective to be implemented and fully effective while being very small in size, thus being particularly suitable to be installed beneath a shower tray (even if it may obviously have other applications) .
  • FIG. 1 is an exploded perspective view of a water drain siphon device in accordance with the invention
  • figure 2 is a longitudinal section view of the device in figure 1 being assembled
  • FIG. 3 is a top plan view of the device in figure 1, with parts removed for clarity;
  • a water drain siphon device 1 comprises a plastic hollow main body 2, which has a tub 3 provided with a top inlet opening 4 and a conduit 5 which laterally projects from tub 3 and extends along an axis A; an essentially annular cover 6, attachable to a peripheral edge 7 of inlet opening 4 and supporting a grid 8 (or another similar outer closure element) on the outside of tub 3; and a conveyor element 9, housed inside tub 3 and coupled to a radially inner collar portion 11, e.g. substantially cylindrical, of cover 6.
  • body 2 formed by tub 3 and conduit 5 is a monolithic hollow body made of plastic, in particular of thermoplastic material; conduit 5 is integrally obtained with tub 3 to form such a monolithic body.
  • Conduit 5 comprises, and preferably consists of, a flattened tube element 10 which is wavy along axis A, the width thereof being greater than the height in cross section, and preferably twice the height; the inner cross section of tube element 10 is preferably (but not necessarily) substantially rectangular with rounded corners .
  • Body 2 is delimited by two opposed lateral sides 13 and by an upper wall 14, provided with inlet opening 4, and a lower wall 15 facing each other. Body 2 further has an end wall 16 joining sides 13 and axially closing a longitudinal end 17 of body 2.
  • Upper wall 14 and lower wall 15 ha-ve respective flat portions 18, 19 and respective wavy portions 20, 21, the wavy portions of one wall facing the flat portions of the opposite wall.

  • Wavy portions 20, 21 are, for example, substantially V-shaped with a rounded vertex.
  • the width of body 2, intended as the distance between sides 13, is greater (in particular, at least twice) than the height of body 2, intended as the vertical distance between upper wall 14 and lower wall
  • Tub 3 is delimited by a lateral wall 23 which consists of the end portions of sides 13 and of end wall
  • tub 3 communicates with conduit 5 through a lateral passage opening 25 substantially orthogonal to axis A.
  • Tub 3 carries cover 6 and houses conveyor element 9.
  • Cover 6 which is advantageously made of thermoplastic material too, is attached to peripheral edge 7 of inlet opening 4 by, for example, heat sealing.
  • cover 6 comprises a substantially cylindrical, inner collar 26 defining radially inner collar portion 11 of cover 6, and a radially outer flange 27 which projects from an upper end of collar 26 and is coupled to peripheral edge 7.
  • Flange 27 carries a support 28 for grid 8, e.g. a frame.
  • Element 9 is inserted into portion 11, which is connected to peripheral edge 7 of inlet opening 4 and projects into tub 3.
  • Element 9 is telescopically coupled to cover 6, namely to portion 11, element 9 being slidingly inserted into portion 11 so as to be orthogonal to inlet opening 4.
  • Element 9 which is preferably made of thermoplastic material, is slidably inserted inside cover 6 up to inferiorly rest against bottom wall 24 of tub 3; element 9 is substantially tube-shaped, e.g. cylindrical, and has a coupling portion 29, a baffle 30 provided with one or more auxiliary openings 31 facing passage opening 25, and support portions 32.
  • Coupling portion 29 optionally carries a substantially annular, elastic radial seal 33 (e.g. CD- ring type) and is coupled to collar 26 (i.e. to portion 11) of cover 6 by an interference fit and in a fluidtight manner; seal 33 is radially interposed between element 9 and portion 11.
  • a substantially annular, elastic radial seal 33 e.g. CD- ring type
  • Baffle 30 faces passage opening 25 and projects from coupling portion 29 towards bottom wall 24 of tub 3; auxiliary opening 31 facing passage opening 25 is defined, for example, by the gap between a lower edge 34 of baffle 29 and bottom wall 24.
  • Support portion 32 consists of one or more pins circumferentially spaced apart from one another, for example, and resting against bottom wall 24.
  • Baffle 30 forms an upper partition 36 which projects downwards (i.e. towards lower wall 15) from upper wall 14 and defines a first water seal 41 within body 2, along with a lower partition 37 consisting of wavy portion 21a, that projects upwards (i.e. towards upper wall 14) from lower wall 15 and is axially spaced apart from upper partition 36.
  • At least a second water seal 42 is arranged within body 2 and arranged in series with first water seal 41 along axis A; second water seal 42 is also defined between an upper partition 46 and a lower partition 47, opposed and axially spaced apart from each other; in this case, as well as lower partition 37 is defined by curved portion 21a-of lower wall 15, for example substantially V-shaped with a rounded vertex, which vertically projects towards flat portion 18a of upper wall 14, lower partition 47 is defined by curved portion 21b of lower wall 15, for example substantially V-shaped with a rounded vertex, which vertically projects towards flat portion 18b of upper wall 14.
  • Upper partition 46 is interposed between lower partitions 37, 47, in this case consisting of curved potion 20 of upper wall 14 which is, in turn, substantially shaped as a V with a rounded vertex, and projecting towards lower wall 15.
  • Lower partition 37 which is closer to tub 3 (or to end 17 of body 2) than lower partition 47 and defines first water seal 41 is higher than lower partition 47 defining second water seal 42; in other terms, first water seal 41, that is closer to tub 3, is higher than second water seal 42, that is farther from tub 3.
  • Lower partitions 37, 47 end with respective upper edges 48, 49 placed at predetermined distances from upper wall 14, so as to define respective passage sections (orthogonal to the axis) above lower partitions 37, 47.
  • Both lower edge 34 of baffle 30 defining upper partition 36 and a lower edge 50 of upper partition 47 are arranged beneath upper edges 48, 49 of lower partitions 37, 47.
  • the passage section (orthogonal to the axis) of tube element 10 at lower partition 37 of first water seal 41 closer to tub 3, is smaller than all subsequent passage sections of tube element 10.
  • Auxiliary opening 31 is entirely arranged beneath the passage section placed at first water seal 41 (i.e. at lower partition 37 which defines first water seal 41) .
  • Conduit 5 further comprises a substantially circular cross section end tube 51, joined to tube element 10 via a joint portion 52 converging towards tube 51 in a horizontal plane, and diverging towards tube 51 in a vertical plane.
