Definitions
- the invention relates to a device for discharging water, also called a drain assembly, in particular for sanitary appliances, for example a drain for a shower tray.
- a drain assembly in particular for sanitary appliances, for example a drain for a shower tray.
- the invention also applies to the emptying of sinks, floor siphons, drainage of rainwater from the roof, etc.
- European patent EP-A-0503232 (Viegener) describes a high flow shower drain which, thanks to a slope integrated in the body of the drain, prevents any residual water stagnating in the bottom of the drain body, but with the exception of course of a minimum guard imposed by the siphon effect.
- the water pours all around the circular wall of a housing to arrive in a chamber or drainage channel whose flat sloping bottom collects the water and guides it on each side of the housing to a tube or evacuation pipe.
- This known shower drain is composed of a casing or housing provided with a supply opening, an evacuation pipe, a fixing flange and a dip tube inserted in the casing, delimiting the feed opening, the casing further having a discharge channel surrounding the casing.
- the evacuation channel has a flat bottom inclined from a high point to an opposite low point so that said evacuation channel guides, in two distinct flows, the water pouring all around the casing towards the manifold. evacuation.
- the design of the drainage channel is such that it creates two separate drainage channels in the direction of the drainage pipe, which disrupts the entry of water into this evacuation pipe and causes a reduction in the speed of water flow and therefore in the evacuation flow, the two generated flows tending to telescope and cause turbulence a pressure drop.
- a shower drain of substantially identical structure is described and in particular having a drainage channel whose bottom has an inclined slope from a high point of the drainage channel to a point bottom of said channel diametrically opposite to the high point.
- This evacuation channel therefore has two arms for guiding the flow of water extending on either side of the housing from this high point of the evacuation channel towards the low point of said channel where these two arms open into a pipe. evacuation.
- German utility model DE-U-9407255 there is also described a device for discharging water comprising an annular discharge channel surrounding the casing and the bottom of which is inclined from a high point of the channel to a low point of said channel. diametrically opposite channel and opening into an evacuation pipe, said evacuation channel in fact defining two evacuation channels.
- the main object of the present invention is to overcome these drawbacks and to propose a device for evacuating water or emptying assembly, in particular for sanitary appliances in which an accelerated flow of water is obtained in the form of a single flow flowing in a drainage channel towards a drainage pipe.
- the subject of the invention is a water evacuation device, also called an emptying assembly, consisting of a central cup into which there opens a water supply opening covered with a cover, with a tube.
- removable plunger inserted into the central cup, an evacuation pipe or tubing as well as an evacuation channel communicating with and surrounding the central cup, said evacuation channel opening at the level of the discharge, characterized in that said discharge channel is unique and has a helical shape descending around the central cup from a high point to a low point of communication with the discharge pipe, said high and low points being substantially aligned in a vertical.
- the inclination of the channel is continuous all along said evacuation channel from a high point to a low point, thus defining a single inclined evacuation channel surrounding the central cup generating a single flow and not a discharge channel divided into two inclined channels on either side of the central cup as was the case in the prior art.
- the drainage channel which is attached all around the cup, constitutes with the latter a one-piece housing forming the body of the evacuation device or emptying assembly.
- This channel is composed of a bottom or lower part comprising the external part of the vertical wall of the cup and an internal part in an arc of a circle open upwards forming a wall coming from the cup, as well as an upper part comprising the internal part. in an arc facing the bottom of the underside of a cover mounted on the housing and the upper end of the vertical wall of the cup.
- the bottom of the central cup consists of a cone connected to the peripheral vertical wall of said cup by a segment in an arc of a circle open upwards.
- the flow of water entering the emptying assembly through the inlet opening and falling inside the dip tube in a vertical falling movement abuts against the conical bottom of the central cup and then undergoes a 180 ° rotation between the outer wall of the dip tube and the inner wall of the cup.
- the water overflows above the vertical wall of said cup in the single discharge channel to follow a downward helical movement imparted to the flow by the channel.
- the vertical wall of the cup is cylindrical so that the major part of the overflowing water arrives in the evacuation channel of helical shape and not directly in the outlet orifice connected to the evacuation pipe.
- the water outlet orifice attached to the discharge pipe is disposed eccentrically, namely in the extension of the lower part of the discharge channel of helical shape.
- the water which flows into the upper part of the outer channel is forced towards the downward helical path by a vertical partition forming the upper abutment of said evacuation channel of helical shape to promote the direction d flow of water in order to avoid any turbulence at the level of communication with the evacuation pipe and to force the single flow to migrate in the direction of flow of the channel in order to undergo the desired acceleration.
- a drainage device ensures a greatly increased flow rate compared to existing water drainage devices due to its unique drainage channel of helical shape accelerating flow, said drainage channel having for a small footprint in its height a longer effective flow length allowing a better acceleration of the flow.
- Figure 1 is a vertical median section of a shower drain according to the invention, the assembly being seen from the front.
- Figure 2 is a perspective view of the shower drain of Figure 1 and its drainage channel.
- Figure 3 is a view identical to Figure 2, but the plug being deprived of all of its upper elements.
- Figure 4 is a flow curve of a plug according to the prior art.
- Figure 5 is a flow curve similar to that of Figure 4, but with a plug according to the invention.
- the water evacuation device or water emptying assembly in particular for sanitary appliances, is in the present example a shower drain for an extra-flat receptacle and comprises a monobloc housing 1 made of plastic, preferably polypropylene, forming the body of the device and comprising a central cup 2 around which is externally attached a discharge channel 3 which has a helical shape opening onto a water outlet orifice attached to a pipe or evacuation pipe 4. It is noted that said water outlet orifice attached to the pipe or pipe 4 is disposed eccentrically, namely in the extension of the lower part of the evacuation channel of helical shape 3.
- the drain has a feed opening defined by interstices 8 formed between an opening cover 9 of the drain and a plate 10 carried by the housing 1, the plate 10 allowing the fixing in a shower tray.
- the bung is fixed around the orifice made in the bottom of the receiving tank 15 using the plate 10 screwable onto a cover 7 mounted on the housing 1.
- the cover 7 covers the drainage channel 3 and at least a part of the central cup 2 while providing an orifice above said cup 2, the plate preferably screwing onto the outer part (orifice side) of said cover 7.
- the seal at the orifice of the tank 15 between these different parts is then ensured by a multifunction seal 16 as described in French patent application n ° 95/08609.
- This seal 16 which encloses by its upper and lower lip the orifice of the receiving tank 15 and the upper external part of the cover 7, is then compressed by tightening the plate 10.
- the device according to the invention can be fixed in a sealed manner from the same way around the opening in the bottom of any other receptacle such as a sink, a floor, a roof in the case of a device for evacuating rainwater from roofs, etc.
- the discharge channel 3 is composed of a lower part 3 ′ comprising the external part of the vertical wall 5 of the cup 2 and the internal part in an arc of a circle 6 ′ open upwards forming a wall 6 coming from the cup 2, thus as an upper part 3 '' comprising the internal part in an arc 7 '' open towards the bottom of the underside of the cover 7 and the upper end of the vertical wall 5 of the cup 2.
- the lower part 3 ′ of the evacuation channel 3 is inclined all around the central cup 2 from a high point to a low point where said evacuation channel 3 communicates with the evacuation pipe 4, the high point and the low point of said discharge channel 3 being substantially aligned in a vertical so that the discharge channel 3 has a helical shape.
- the water flow enters the emptying assembly through the interstices 8 formed between the cover 9 and the plate 10.
- the flow drops inside the dip tube 11 which is composed of a sort of filter basket, removable thanks to a central gripping device, placed against the internal vertical walls of the tray 10.
- the flow abuts against the conical bottom 12 of the cup 2 and then undergoes a 180 ° rotation thanks to a segment in an arc of a circle 13 open upwards, formed between said conical bottom 12 and the vertical wall 5 of the cup 2.
- the flow thus deflected rises between the external wall of the dip tube 11 and the internal face of the vertical wall 5 of the cup 2.
- the latter once filled, the water overflows above the vertical wall 5 of said cup 2 and fall into the evacuation channel 3 of peripheral helical shape to follow a descending accelerating movement towards the water outlet orifice of the evacuation channel 3 communicating with the evacuation pipe 4.
- FIG. 3 which represents the only lower part 3 ′ of the plug body shows the entire location of the helical channel 3 as well as the vertical partition 14 forming the upper abutment thereof and promoting the direction of flow in said channel 3
- the highest part of the channel 3 is substantially aligned in a vertical with the lowest part of said channel 3 at the periphery of the central cup 2.
- the slope of the bottom of said channel 3 tilts from this upper part to the lower part continuously and defined around the central cup a single discharge channel 3 of helical shape, defining a single flow of helical path.
- the evacuation pipe 4 for water outlet is formed in the present example using a ball socket 17 provided an O-ring 18, a conical seal with a screwable ring 19 and an elbow 4 at 135 °.
- the assembly thus formed can be placed on the discharge pipe at a variable angle of 30 °, which greatly contributes to the ease of implementation of the plug between the receiver tank 15 and said discharge pipe 4.
- Figure 4 shows the measurements taken in a tank provided with a traditional drain
- Figure 5 uses a drain according to the invention.
- the drain according to the invention not only authorizes much greater water flow rates than with the bungs of the prior art, but also makes it possible to maintain the low height of water required with the extra-flat receiving tanks. It also goes without saying that the increased speed of evacuation of water avoids frequent fouling of the system as observed in many cases with the bungs of the prior art.
- the outlet for water coming from the drain is provided in the lower part of the discharge channel in a central plane passing through the axis of the plate.
