Definitions
- the invention relates to a siphon or drain for shower tray.
- a shower tray has an average height of between 18 cm and 10 cm, which promotes the flow of water that receives the receiver. This channelized water reaches the lowest point and, by design of the receiver, is eliminated through a bung or siphon.
- the usual standards require that a 50 mm hydraulic occlusion be made in this bung so as to avoid the rise of odors coming from the sewer.
- the document US 2011/289673 discloses a shower tray having a pumping device located in a recess of the receiver.
- the document DE 10 2011 107 817 describes an automated pump with pneumatic control and the document EP 2 489 800 discloses a sewage lift pump having a level sensor.
- the best-known system is to position and move the most far away from each other two electrodes paired with an electronic control.
- soapy water arrives, a slight electric current is established between the electrodes and the pump starts.
- this system requires maintenance because traces of residual water at the bottom of the receiver can create a conductive biofilm and the pump can not stop.
- very pure water volatile source
- Reed bulb Another known system operates on a magnetic principle and uses a commercial component known as the Reed bulb.
- This cylindrical bulb contains, in a glass envelope, two thin blades which have contact bulbs at the top and are sensitive to a magnetic field.
- the flexible membrane (for example made of an EPEM material or silicone), deforming during the rise of water, allows the engagement of the microswitch which is connected to a pump. This makes it possible to control the pump and stop it at the end of the cycle when the water in the siphon body has reached its low point.
- the advantage of this principle is that it is not sensitive to the quality of the water to be evacuated, nor to its temperature.
- the diaphragm, operating part can be changed easily if necessary after a long period of use.
- the microswitch can be chosen initially, among the ranges existing at many manufacturers, for its quality of flexibility and reliability.
- its basic size makes it possible to establish safer electrical contacts than in the miniaturization that is needed in a Reed bulb.
- the siphon according to the invention is particularly simple design and installation.
- the housing comprising the pressure switch (membrane and microswitch) is mounted simply and removably inside the siphon body, which facilitates maintenance operations.
- the figure 1 represents in section a siphon 10 arranged below a tray shower tray 12 of which only a flange 14 has been shown.
- the siphon 10 comprises a container or cylindrical body 16 (plug) open on top to provide in the body a water inlet 18 from the tray.
- the body 16 is laterally connected to a conduit 20 for discharging the water which enters said body through the upper opening water inlet 18 covered with a grid 21.
- the water discharge duct 20 is connected hydraulically to a suction pump 22 which has the function of sucking, on command, the water present in the body 16.
- the set of elements represented on the figure 2 form a water drain device of shower tray.
- the body 16 comprises a side wall 16a and a bottom wall 16b disposed vis-à-vis the upper water inlet opening 18.
- An oblong hole 24 is formed in the side wall 16a of the body and extends outwardly of the body, away from the wall, by an oval skirt 26 in which is inserted axially a check valve system 28 which prevents any inadvertent return of water.
- the check valve system comprises a hollow portion (30) in the form of a flexible (elastically deformable) duckbill which comprises a first end 30a to the flattened lips through which the water comes out and a second enlarged opposite end 30b which projects from the
- the non-return valve system also comprises a rigid insert portion 32 (hoop) which is inserted into the duckbill-shaped hollow portion 30 through the non-return valve system. second end 30b. This allows the valve system to be shaped and sealed between the outer surface of the duckbill part 30 and the inner surface of the skirt 26 of the exhaust duct.
- the rigid insert portion 32 opens into the body 16 and is provided with an opening 34 to allow water in the body to enter the check valve system.
- the water inlet opening 34 is positioned facing the bottom wall 16b of the body and as close as possible thereto in order to be able to evacuate as much water as possible from the body.
- the oval skirt 26 of the exhaust duct is capped at its open end (end opposite to the oblong hole) of a shell 36 which is designed to be glued to said end and which transforms the oval shape into a cylindrical shape so that it can be connected downstream to an evacuation pipe.
- the siphon 10 also comprises a member 40 acting as an axial stop of the check valve system 28 which is engaged in the skirt 26 of the exhaust duct to prevent axial removal of said system.
- the abutment member 40 is removably mounted in the side wall 16a of the siphon body near the discharge duct 20 ( Fig. 1 ).
- the member 40 is for example housed in a cavity 42 formed above the oblong hole 24.
- the abutment member 40 comprises a first portion 40a which is inserted into the cavity and a second portion 40b, external to the cavity, which forms an elbow with respect to the first portion and which can pivot relative to the latter ( Fig. 3 ).
- the second portion 40b serves as a gripping element for the manipulation of the organ.
- the first portion 40a is first introduced into the cavity 42 with the second portion 40b positioned either horizontally or raised (installation position). Then, the second portion 40b of the member is pivoted downwards so that it comes to be positioned in front of the part of the insert 32 which opens into the body from the oblong hole 24, thus preventing any axial withdrawal of the system. Valve (stop / lock position). The stop member 40 thus holds the valve system in position.
- the siphon 10 further comprises a housing 50 which is removably mounted on the bottom wall 16b of the body ( Figs. 1 and 6 ) in order to be easily installed in the body 16 and removed from the latter.
- the microswitch 54 is set in a cage 56 provided with gripping claws 58 which ensure its maintenance in position above the membrane 52.
- the housing 50 also comprises a wire link in the form of two son 60a, 60b shown in dashed lines connecting the microswitch 54 to two respective terminals of an electrical connector 62 of a first type connected to the housing and which extends to the outside said case.
- the housing 50 comprises a substantially cylindrical casing 64 surrounding a central housing in which is disposed the microswitch 54 encased in its cage.
- the envelope 64 is open at the bottom and has a lower peripheral edge 64a delimiting this opening in which the membrane 52 is placed in order to seal said opening.
- the housing 50 comprises a flange 66 which maintains an outer peripheral zone 52c of the membrane at the level of said lower peripheral edge 64a ( Fig. 4 ) and which is attached to the housing detachably in order to be able to remove the membrane at leisure.
- the lower peripheral edge 64a is provided on an outer peripheral edge 64b with a plurality of circumferentially distributed teeth 64c, and the collar 66 has a plurality of circumferentially arranged slots 66a, some of which fit on respective teeth arranged in correspondence to each other. the attachment of said flange.
- feet 68 are attached to the underside of the collar, for example three, to allow the housing to rest on the bottom wall while keeping the membrane away from it. Only some of the three feet are represented on the figures 1 , 5 and 6 .
- a partially hollow horizontal arm 70 extends radially from the upper part 64d of the casing of the casing and away from it and is extended downwards by a hollow vertical arm 72 at the bottom of which is fixed the electrical connector of the first type 62, for example of the male type.
- the arrangement of these arms forms a beak directed downwards.
- This connector 62 exits the free end 72a of the vertical arm and extends downwards, towards the bottom wall of the siphon body.
- the hollow parts arms 70, 72 serve to pass electrical wires 60a, 60b connecting the microswitch 54 to the aforementioned connector 62.
- the entire interior thereof is for example filled with an epoxy resin serving as a seal and embedding the electrical son.
- the envelope is then covered at its upper part 64d by an oblong cover 73 which can be fixed permanently or not to the envelope.
- a vent hole 74 (shown in dotted lines) is formed in the wall thickness of the downward vertical arm 72 to communicate the inside of the housing and the outside thereof. This balances the pressure of the inside of the housing and that of the outside, which can prevent malfunctions of the pressure switch. (ex: residual deformations of the membrane which could disturb the operation of the pressure switch).
