DESCRIPTION

A device in a sink with a siphon and a basin valve of the emerging type Field of the invention

The present invention relates to a device in a washbasin, device comprising a siphon and a basin sink valve, basin sink valve that is of the emerging type (in English, "pop-up"), which implies that the basin valve has a valve opening and a valve plate that is arranged to be able to adopt an upper open position and a lower closed position when the valve plate closes the valve opening, the valve plate being arranged to be movable from the open position to the closed position and vice versa by applying a compression force on the upper side of the valve plate, compression force that is of a magnitude that is easily produced by manual force.

In the present application the terms upper, lower, up, down, etc. are used. These terms refer to the device when it is installed in a sink and has a vertically directed drain.

In addition, the terms radial, axial and circumferential direction refer to the axial direction defined by the vertical drain of the sink.

Background of the invention

Recently, the so-called emerging valves (or "pop-up") to maneuver a sink basin valve between their closed and open positions are becoming more common. Users generally find the maneuver of a valve of this type more comfortable than other maneuvering alternatives. In addition, the design is made simpler in comparison with the case in which the maneuver is carried out by means of a lever that is arranged in the sink and that actuates the valve through an articulation.

Several alternative designs are known for the emergent mechanism of closing and opening of the valve. A couple of examples of such mechanisms are described in US 4144599 and US 6219861.

Document DE 102006042622 A1 describes a device for a washbasin that has an extralble siphon. US 2004/226085 A1 describes a sink plug with an emerging valve.

A drawback of conventional emerging valves is that they are installed in the sink basin so that the removal of the valve body requires work under the sink, where its attachment is located, which complicates, for example, repairs or other operations of necessary maintenance.

Under the sink sink, there is usually a siphon or hydraulic trap between the valve opening and the drain pipe. To clean the siphon it is necessary to work under the sink to perform said cleaning. To facilitate the cleaning of the siphon, it is previously known, from WO9612071, a siphon that is configured to be able to extract it upwards through the opening of the basin valve, which facilitates cleaning.

The object of the present invention is to avoid the disadvantages associated with conventional emerging valves and at the same time allow the simplified disassembly of a siphon as described in WO9612071 mentioned above.

Description of the invention

The exposed object is achieved by the present invention by the fact that a device of the type mentioned by way of introduction has the special characteristics that the siphon has an external dimension that allows its passage through the valve opening, which the plate Valve is coupled to the siphon by means of a connection device that detachably connects the siphon with the valve plate, so that the siphon accompanies the valve plate when the valve plate is lifted from the sink, and that the siphon It has locking members for detachable axial fixing of the siphon.

Because the valve plate of the pop-up valve is connected to the siphon instead of being installed on the sink basin by means of a fastener according to the prior art, the disassembly of the valve plate is facilitated. The fact that the siphon to which the valve plate is connected can be removed through the valve opening together with the valve plate also contributes to this. In this way, use is also made of the advantages presented by the siphon described in WO9612071 mentioned above, that is, ease of disassembly during, for example, cleaning. Due to the fact that the axial fixation of the siphon is removable, this function is made possible without affecting the maneuvering function of the emerging valve in other aspects. Axial fixation is needed to provide a support for the emergence mechanism.

Consequently, the invented device constitutes a global solution that combines a convenient maneuver of the valve with a simple disassembly of the valve and the siphon for cleaning and attention.

According to a preferred embodiment, the siphon comprises a tube piece and a cup piece provided with a bottom, cup piece inside which the tube piece partially protrudes.

The cup piece and the tube piece that protrudes inside it provide, in a simple and effective way, the siphon function. Together with a surrounding outer tube, a flow path is formed from the cup piece, above its edge and down between its outside and the outer tube.

According to a further preferred embodiment, the device comprises a tubular housing that has an upper end attached to the sink and connected to the valve opening, and a lower end for connection to a drain pipe, the siphon being arranged in said housing.

By cooperating in this way the siphon with a surrounding tubular housing, the upward extraction of the siphon itself and the correct relocation thereof are facilitated. At the same time, the duct communication between the valve opening and the drain pipe is maintained.

According to the invention, the siphon locking element is connected to the housing by means of a removable joint.

This ensures an axial fixation of the siphon in a simple way, while the possibility of disassembly makes it easy to lift the siphon when necessary.

According to a further preferred embodiment, the removable joint comprises openings in the housing and locking lugs in the tube piece, these locking lugs being arranged to be fitted in and out of the openings.

In this way, the removable joint is provided in an easy and easily maneuverable manner.

According to a further preferred embodiment, the tube piece has upwardly directed tongues, of which a respective locking lug radially protrudes, each locking lug having a cam profile, for example an arc-shaped profile, in the circumferential direction .

By mounting on tabs, a spring action is obtained in a simple manner that facilitates the joint coupling of the joint. The arc profile of the locking lugs makes it possible to easily extract said lugs out of the openings when the tube part is rotated, thanks to the cam action that originates between the arc profile and the side edge of the respective opening. Alternatively, the cam profile can be provided by chamfers directed outward towards the peripheral side edges of the locking lug.

According to a further preferred embodiment, the tube piece has upwardly directed tongues, of which a respective locking lug radially protrudes, each locking lug having a cam profile, for example an arc-shaped profile, in the top in the axial direction.

By this alternative embodiment, the siphon can be pulled up, and the cam action of the arc profile or an oblique bevel presses out the locking tabs towards the upper edge of the respective opening. The spring force of the tabs ensures that the locking lugs are in a locking position with small axial forces, such as those produced when maneuvering the emerging valve. An axial force directed upwards more intense, but still moderate, releases the locking lugs.

According to a further preferred embodiment, the connection device between the valve plate and the siphon is removably arranged.

Thus, it is possible that the valve plate can be easily separated from the siphon, which allows only the valve plate to be removed.

According to a further preferred embodiment, the connection device comprises a bayonet plug.

A bayonet plug offers a simple and reliable solution to be able to separate the valve plate from the siphon, where a simple rotational movement of the valve plate offers the two connection positions to extract by pulling up the valve plate alone or, respectively, along with the siphon.

As an alternative, the valve plate, with its connection piece, can be screwed into the siphon.

According to a further preferred embodiment, the tube piece and the cup piece are interconnected by a removable coupling device, the surrounding housing being arranged to retain the coupling device in a crimping manner when the siphon is in place in the surrounding housing.

The coupling device ensures that one piece accompanies the other when it is lifted. Thanks to the fact that it is removable, it allows some pieces to be separated from others when the siphon is disassembled, which facilitates efficient cleaning.

According to a further preferred embodiment, the tube piece has an upper section and a lower section, a lower section that has an external diameter smaller than the upper section, the upper section having at least one depression outside and the cup piece being provided , in an upper part thereof, of at least one projection radially inwardly directed adapted to protrude into the depression, to form said coupling device.

In this way, the detachable coupling device is provided in an easy and convenient manner, where the surrounding tubular housing abuts against the top of the cup piece in order to retain the projection inserted in the depression.

According to a further preferred embodiment, a wall under the siphon is arranged in the tubular housing.

When the siphon is removed, there is a completely free passage from the valve opening down to the drain pipe. This carries the risk that objects that fall, for example a wedding ring, may be lost down through the drain. By arranging the wall according to this realization, it is possible to grasp these objects.

According to a further embodiment, a secondary siphon device is arranged under the siphon, said wall being part of the secondary siphon device.

When a sink that has a simple siphon has not been used for a long time, there is a risk that it will dry out, which causes the spread of a bad smell. This risk is reduced by the secondary siphon device. The secondary siphon device does not need to be liftable, since it is exposed to dirt to a very small extent. In addition, the secondary siphon collects objects that fall, thus fulfilling! the function of the wall mentioned in the realization mentioned just above.

The preferred embodiments of the invention mentioned above are defined in the claims dependent on revindication 1. It should be noted that, of course, additional preferred embodiments may consist of all possible combinations of the above-mentioned preferred embodiments.

The invention is explained in more detail by the following description of illustrative embodiments thereof, referring to the attached figures.

Detailed description of illustrative embodiments

Figure 1 is a longitudinal section through a first illustrative embodiment of a device according to the invention. The device comprises a valve 1, a siphon 2 and a surrounding tubular housing 3, the components being arranged at the outlet of a washbasin 4.

The valve has a valve plate 101 that is applied so as to close a valve seat 102, in the form of a ring, the valve opening being surrounded by the valve seat 102 when it is closed. The Figure shows the valve in the open position, in which water can flow out between the valve plate 101 and the valve seat 102, through the opening of the valve and through the siphon 2, going down towards the pipe 6 of drain connected to tubular housing 4.

The valve is a valve of the type known as "emergent", that is, the closing of the valve is carried out by applying a slight compression force on the valve plate 101 with the hand so that it rests against the seat 102 of valve. The opening of the valve is carried out analogously by quickly pressing down on the valve plate 101, which then jumps upwards by means of a mechanism 103 to "emerge",

The emergent mechanism can be realized according to the main structure described in any of the documents US 4144599 or 6219861 mentioned at the beginning, or by the use of some other conventional mechanism of this type.

A connection device 104 connects the valve plate and the emerging mechanism thereof with the siphon 2.

The siphon 2 is composed of a piece 201 of tube and a piece 204 of cup. The tube part 201 has an upper section 202 and a lower section 203, where the lower section 203 has an external diameter smaller than the upper section 202.

The siphon is surrounded by a tubular housing 3, which has an upper part 301 with an external diameter smaller than its lower part 302. The lower part 302 of the housing has an internal diameter larger than the external diameter of the lower section 203 of the tube part 201, to form a flow path between them. The upper part 301 of the housing is inserted so that it closes in a hole at the bottom of the sink and is connected to the valve seat 102. Advantageously, the upper and lower housing parts are separate parts.

The siphon is detachably attached to the upper part 301 of the housing, in a manner that axially fixes the siphon in the housing so that the function of the emerging valve is guaranteed. The possibility of disassembly means that the siphon can be removed outside the housing. Examples of this union are described in more detail in relation to Figures 6-8.

The internal diameter of the upper part 301 of the housing 3 is somewhat larger than the external diameter of the upper section 202 of the siphon tube part 201, and between them a sealing ring is arranged. The cup piece 204 of the siphon is composed of a bottom 206 and a cylindrical wall 205 directed upwards, connected therewith. The cylindrical wall 205 has an external diameter smaller than the internal diameter of the upper part 301 of the housing 3. Accordingly, the relative dimensions of the components allow the siphon to be pulled up through the upper part 301 of the housing 3. The connection device 104 is connected to the upper section 202 of the siphon tube part 201 by means of a bayonet plug having a radially protruding pin 105.

The valve plate 101 can be lifted from the sink by means of the bayonet closure. In a certain position of rotation of the pin 105, the upper section 202 is connected so that it accompanies the valve plate 101 upwards when the latter is lifted. This is achieved by the fact that the upper tube section 202, above the pin 105, has an inwardly directed flange portion 208 (see Figure 2) that extends at a certain angle, for example, 90 °, in circumferential direction. By rotating the valve plate 101 to a position where the pin 105 of the bayonet plug is just in front of the flange part 208 in the circumferential direction, the required axial locking action is provided between the pin and the flange part 208 .

In addition, the cup piece 204 is connected to the tube part 201 in a suitable manner, so that the cup piece also accompanies it upwards. In this way, the entire siphon 2 can be lifted by means of the valve plate 101.

Figure 2 is a section along line II-II of Figure 1, through the connection device 104 and the upper section 202, and shows the connection when the siphon is raised. Consequently, the pin 105 is in a rotating position in which it is located under the flange part 208. The turning of the pin in a quarter turn from the position shown uncouples the blockage, and the valve can be removed without the siphon accompanying it.

Figure 3 is a section through a piece of a device according to the invention, according to a second illustrative embodiment, and illustrates an alternative to the way in which the cup piece 204 and the tube piece are joined together. This figure omits, for the sake of clarity, the upper part of the device with the connection to the pop-up valve.

In its upper section 202, the tube part 201 has two ring-shaped slots 209, 211 on the outside. In the upper one, 209, of said grooves, a closing ring 210 is arranged and is supported so as to close against the inside of the upper part 301 of the tubular housing 3. The lower groove 211 serves to join with the part 204 of siphon cup At its top, the cylindrical wall 205 of the cup portion is provided with several upwardly directed tabs 213, each of which has a projection 212 directed radially inwardly. The projections 212 directed inwardly protrude into the depression 211 which is formed by the groove 211, so that a connection is established between the cup piece 204 and the tube part 201. When the siphon 2 is in place in the housing 3, the protrusions 212 are retained in place in the groove 211 by the upper part 301 of the housing 3.

When the siphon has been removed from the sink, it is easy to undo this joint, since the tabs 213 are flexible. In this way, the siphon cleaning is facilitated.

Figure 3 also shows how the upper part 301 of the housing 3 can be connected with its lower part 302, wherein the lower part 302, which has an upper circular edge, is screwed into an external thread of the upper part 301.

Figure 4 is a section through the cup piece 204 of Figure 3, in which the tabs 213 having protrusions 212 are arranged.

In the illustrative embodiment illustrated in Figure 5, the device is provided with a removable joint between the upper part 301 of the tubular housing 3 and the tube part 201 of the siphon. The upper part 301 of the housing has three openings 303, which can be connected to an overflow of the sink. In addition, there are locking lugs 215 in the form of protrusions directed outwardly on tabs 214, which constitute an upward extension of the upper tube section 202. The locking lugs 215 have an arc-shaped profile in the circumferential direction, for example, in the form of a circular arc.

In this example, the connection between the valve plate 101 and the siphon 2 is such that the siphon 2 can be rotated by rotating the valve plate. When the siphon 2 is rotated in this way, the locking lugs, due to their arc shape, will be pressed inwards, overcoming the spring force of the tabs 214 so that they are disengaged from the openings 303. In this position , the valve plate 101 together with the entire siphon 2 can be lifted out of the housing and removed from the sink.

Alternatively, the locking lugs may have an arc-shaped or chamfered profile in the axial direction.

Figures 11 and 12 illustrate locking tabs 215 arranged to allow them to be pulled up and rotated, respectively, to release them from opening 303.

When the siphon has to be reassembled, it is pushed down into the housing 3 until the locking lugs 215 are flush with the openings 303 which, eventually after a certain turn, fit into these by virtue of the spring action of the tabs 214. When the locking lugs are in place in the openings, the axial movement of the siphon 2 is stopped.

Figure 6 illustrates the device of Figure 5 in an exploded view. The siphon 2 is partially pulled upwards out of the upper part 301 of the tubular casing, and the valve plate 101, with the emerging mechanism thereof, is pulled upwardly upwards from the siphon 2. The cup piece 204 of the The siphon is protruding partly downwards into the interior of the housing 3, and the tube piece has the lower section 203 thereof protruding partly downwards into the interior of the cup piece. In its upper section 202, the groove 211 can be seen in which, in the assembled state, the cup piece 204 is joined by the protrusions 212 of the tabs 213. Above, the closing ring 210 is visible.

From the upper section 202 of the tube piece, the tabs 214 having locking lugs 215 extend by means of which the siphon is fixed in the housing 301 in the assembled state, the locking lugs protruding inside the openings 303 of the housing 301.

Figure 7 illustrates the device of Figure 6 at a stage in which the siphon is being pushed into the housing 3. In Figure 8, the siphon is in place in the housing and the locking lugs 215 are in the openings 303. You can see, below the upper part of the housing, the siphon 2 having the tube piece 203 thereof protruding inwards into the cup part 205. In Figures 5-7 only the upper part 301 of the housing 3 is shown. As indicated by the dashed lines of Figure 7, the housing also has a lower part 302 having a diameter somewhat larger than the upper part 301 of the and surrounding the cup piece 204 of the siphon 2 in a manner similar to that illustrated in Figures 1 and 2.

Figure 9 is a section through a part of a device according to another illustrative embodiment of the invention. In this case, the device is provided with a secondary siphon device 5.

The secondary siphon device 5 is formed by a downwardly directed cylindrical wall 501 attached to the bottom side of the siphon cup piece 2 located above, and a tube unit 502 arranged inside the cylindrical wall 501. In the upper part, the tube unit 502 is provided with an oblique wall 503. The arrows indicate the path of the water flow through the double siphon assembly.

When the upper siphon 2 is lifted in the manner described above, it is also accompanied by the downwardly directed cylindrical wall 501. The oblique wall 503 prevents loose objects falling through the exit of the sink from being lost down in the pipe 6 of drain.

Also in the embodiment of the invention in which there is no secondary siphon device, a wall corresponding to the wall 503 can be arranged in order to prevent broth objects from being lost down in the drain pipe 6.

Figure 10 illustrates a second embodiment that has a double siphon. In this embodiment, device 5 of

underlying siphon is formed by an inverted cup-shaped piece having an upper wall 505, from which a cylindrical wall 504 directed downwards protrudes downwards. In the cylindrical wall 504 several openings 506 have been made for water to pass through. In this illustrative embodiment, the entire lower siphon device 5 is left behind when the upper siphon 2 is raised.

5 Conveniently, the siphon is made of PVC plastic that is suitable to withstand cold or hot water and provides a dimensionally stable construction.
