Description

The present invention relates to an evacuation device for a tank.

sanitary facilities, and more

  especially for shower trays.

  Most shower trays are built into the masonry, which does not allow access to the infrastructure of said tanks, in particular for the purpose of

  detect a malfunction such as a leak.

  On the other hand, for the same reasons, when the siphon is blocked it is difficult, if not impossible, to dismantle it to unclog it. Uncorking is therefore carried out from above, using various utensils, often unsuitable for this operation, and which generally do not

  allow only a partial unclogging of the siphon.

  The object of the present invention is to remedy these drawbacks by proposing an evacuation device for a sanitary installation tray, which allows the inspection of the infrastructure of said tanks, as well as an unblocking.

  fast and complete in the event of obstruction.

  The evacuation device which is the subject of the present invention comprises a siphon comprising a siphoid intermediate part and two mouths, an inlet mouth connected to a drain, itself integral with the tank, and an outlet mouth connected to a conduit. evacuation; and it is essentially characterized in that on the one hand said siphon comprises at least one elastically deformable part, and on the other hand said inlet mouth is reversibly separable from said plug, while the outlet mouth remains integral with said

exhaust duct.

  According to an additional characteristic of the device according to the invention, the siphon is produced in a

  elastic material of the elastomer type.

  According to another additional characteristic of the device according to the invention, the siphon is made of a semi-rigid material and it has at least one part in

  bellows shape allowing its deformation.

  According to another additional characteristic of the device according to the invention on the one hand the inlet mouth of the siphon is of flared shape and has a peripheral lip, and on the other hand said drain includes a drain plug and a housing part for the inlet mouth of the siphon, a retaining washer securing said plug to the receiver and said siphon being secured in a sealed manner to said plug by pinching said peripheral lip between the plug cap and the piece of

housing.

  According to another additional characteristic of the device according to the invention, the retaining washer has an extension intended to receive the outlet mouth of the siphon for its connection to the conduit.

evacuation.

  According to a variant of the device according to the invention, the retaining washer comprises an extension capable of receiving the outlet mouth of the siphon and

  to support its intermediate siphoid part.

  The advantages and features of the present invention will become more apparent from the

  description which follows and which relates to the appended drawing,

  which represents a non-limiting embodiment thereof.

  In the accompanying drawing: - Figure 1 shows a schematic view in partial section of a discharge device according to the invention. - Figure 2 shows a schematic view in partial section of the same device during an operation of

unblocking and / or inspection.

  - Figure 3 shows a schematic view in partial section of the same device during an operation

  inspection and / or unblocking according to a variant.

  - Figure 4 shows a sectional view along a median vertical plane of a discharge device according to the invention in a particular embodiment of the

bung retaining washer.

  - Figure 5 shows a sectional view along a median vertical plane of a discharge device according to the invention in another embodiment of the washer for holding the plug. If we refer to Figure 1, we can see that a discharge device according to the invention comprises a siphon 1 secured to a shower tray 2 via a drain 3 secured to the receiver 2 at

  level of the emptying hole 20 thereof.

  The siphon 1 comprises a flared inlet mouth 10, intended to be connected to the drain 3, a siphoid intermediate part 11 and an outlet mouth 12 intended to be connected to a discharge duct, not

represented.

  The siphon 1 is elastically deformable, so that, as shown in FIG. 2, the inlet mouth 10 can be separated from the drain 3, and the siphon 1 can be partially extracted from the

  receiver 2 passing through the drain 3.

  The flared mouth 10 can thus be maintained above the receiver 2 while the intermediate part 11 is extended which allows the plug formed therein to be removed. Note that the evacuation of the plug can be facilitated by the pouring of water into the mouth

input 10.

  When it comes to inspecting the infrastructure of the receiver 2, it is not necessary to extract the siphon 1 by the drain 3, it suffices to separate it from the latter and to move it, which is easily and without damage due to its flexibility, as can be seen in Figure 3, which allows the user for example

  to introduce a mirror under the receiver.

  The elasticity of the siphon 1 can be obtained in different ways, this can be achieved either in an elastic material of the elastomer type, or in a semi-rigid material and then comprise, in particular at the level of the intermediate part 10 and more particularly at

  ends thereof, bellows-shaped areas.

  Referring now to Figure 4 we can see that according to a particular embodiment of the discharge device according to the invention, the inlet mouth 10 of the siphon 1 has at its end a peripheral lip 13, and, under this one, a peripheral groove

14.

  On the other hand, it can be seen that the bung 3 comprises a bung cap 33 secured to the upper part of a housing part 31, engaged in the emptying hole 20, comprising an opening 32 in which the end takes place of the inlet mouth 10 of the siphon 1 covered by the bung 33 which pinches the lip 13, the bung 3 being secured to the receiver 2 by means of a retaining washer 30 which is extended, perpendicular to the latter, by a wall 38 having an opening intended to receive the outlet mouth 12

siphon 1.

  The setting of the siphon 1 in the drain 3 is moreover ensured by a peripheral rib 35 projecting

  of the internal wall 36 of the intermediate piece 31.

  Referring now to FIG. 5, it can be seen that the retaining washer 30 has the form of a box in which the siphon 1 is enclosed. The box 30 has a first opening made in one of its vertical sides 39 intended to receive the outlet mouth 12 and a second opening made in its upper face 39 intended to receive the inlet mouth 10

siphon 1.

  When the siphon 1 and in particular the siphoid intermediate part 11 are made of a flexible material, the bottom 37 of the box 30 advantageously makes it possible to support the siphon intermediate part 11 containing part of the water discharged by the siphon 1 deformed at its base by the weight of the latter and thus maintain the water guard. The connections between on the one hand the box 30 and the housing part 31, and on the other hand between the housing part 31 and the bung cap 33, are produced by appropriate means, allowing an easy and rapid intervention, c that is to say by snap-fitting, by embedding, by

  screwing or any other means of securing.

  Note that seals, not shown, are interposed between parts 30 and 31 and the

receiver 2.

  According to one embodiment, not shown, the rigid holding part 30 has a sleeve at one end of which fits the outlet mouth 12 of the siphon 1, while the discharge duct fits

the other extremity.
