Description

Sanitary product device

Technical Field

The invention relates to a sanitary fitting with an integrated throttle valve according to the preamble of claim 1.

Background

DE 3128525 shows a toilet pan with a fitting. The insert includes a channel with an inlet and a plurality of outlets. The cross section of the water outlet can be adapted to the flushing water pressure by means of an inner part which can be inserted into the insert.

The technical teaching of DE 3128525 has the disadvantages that: the adjustment is performed before the toilet bowl is connected. After successful adjustment, the toilet bowl is connected to the flushing line. Immediately after the first flush is initiated, the installer can then conclude that: whether the previous adjustment was good or also has to be optimized. If further adjustment is required, the flushing line must be dismantled again before the insert can be modified. After that, when the installer connects the flushing pipe again and starts the first flushing, it is possible to re-observe whether the adjustment is good again.

Disclosure of Invention

Based on the prior art, the present invention aims at: a sanitary device according to the invention is proposed which can be adjusted more effectively in the technical field mentioned at the beginning.

The sanitary product arrangement as claimed in claim 1 achieves this object. According to this claim, the sanitary product means comprise: a hygiene product having a collection basin, an inlet into the collection basin and an outlet leading from the collection basin; and a conduit member in fluid connection with the inlet, having a wall surrounding the passage and a throttling element by means of which the cross-section of the passage can be varied in order to regulate the inflow of flushing water into the sanitary product. The plumbing can be connected to a source of flush water that provides flush water for injection into the collection basin. The throttling element is arranged in the sanitary product in such a way that it can be adjusted in a state in which it is in fluid connection with a source of flushing water. In other words: the throttle element is configured such that it can be adjusted when the sanitary product is installed and the line piece is installed.

The advantages of configuring the throttling element such that it is adjustable in fluid connection with the source of flushing water are: the installer can very simply adjust the restriction element under locally given conditions, i.e. given flushing water pressure and/or sump shape. In particular, the installer can initiate a flush test and then check the effectiveness of the flush test in the collection tank. For example, if overflow of the rinsing water occurs in the collection sump, the passage cross section can be reduced. If the desired level of the rinsing water in the collecting basin is not reached, the passage cross-section can be increased. The installer can adjust the throttling element without disassembling the sanitary product arrangement, thereby greatly simplifying assembly of the sanitary product arrangement.

The hygiene product is preferably a toilet or urinal.

The expression "adjustable" is understood to mean: the throttling element can be adjusted by the installer. That is, the installer performs an adjustment that is not modifiable after the adjustment is successful. In other words: the throttling element can be adjusted manually or by means of a tool in the state of fluid connection with the flushing water source, while the adjustment of the throttling element remains unchanged after successful adjustment throughout the life of the sanitary product arrangement.

Preferably, the throttle element is mechanically moved relative to the passage during the adjustment and is secured in its position after a successful adjustment, whereby the position of the throttle element is unchanged during the water flow.

The throttling element is arranged in the sanitary product in such a way that it is accessible from the outside of the sanitary product in a state in which it is in fluid connection with a source of flushing water.

In a first solution, the duct element is constructed independently of the sanitary products and is in contact with said sanitary products by means of a watertight connection. In this embodiment, the line piece is preferably made of a synthetic material. Wherein the piping element has a connection part connectable with the inlet. For example, the connecting member can be inserted into the inlet and bonded to the hygiene product device.

In a second variant, the line piece is an integral component of the sanitary product. Wherein the duct member constitutes an integrated inflow part of the inlet.

In both solutions, the part of the throttling element that causes the change in the cross-section of the passage can be arranged inside or outside the passage.

The throttling element preferably comprises a throttling member and a driving member. The throttling element extends into the passage. Thereby, the passage cross section can be changed by the throttle element. The drive member protrudes out of the tubing member so that the drive member is accessible from outside the channel. The change in the cross section is achieved by the drive member being able to change the position of the throttle member in the passage. Particularly preferably, the throttle element can be rotated in the passage by twisting.

The drive member is arranged on the sanitary product in such a way that it is accessible after the sanitary product has been mounted, so that the throttle member can be adjusted after the sanitary product has been mounted.

In a first embodiment, the drive member comprises a receptacle for receiving a tool. For example, the receptacle can be a slotted receptacle, an internal hexagonal receptacle, an external hexagonal receptacle or a Trox receptacle. Other shapes are also contemplated.

In a second embodiment, the drive member comprises a drive element that can be grasped by hand.

The drive member preferably includes an externally visible marking which indicates to the installer the orientation of the throttling member in the passage.

The throttle member preferably comprises at least one flat area which is configured to be rotatable in the duct element about the axis of rotation. The channel cross section can be changed by rotating the plane area. The largest cross-section is provided if the main plane of the planar area is in the flow direction. The smallest cross section is provided if the main plane of the planar area is transverse to the flow direction.

It is particularly preferred that two planar regions extend outwardly from the axis of rotation, the two planar regions being oriented in a plane through which the axis of rotation passes.

Preferably, the throttling element comprises a bearing part between the drive part and the throttling part. The wall portion includes a support hole through which the throttling element is rotatably supported.

Preferably, the bearing hole penetrates the wall so that the throttling element can be inserted into the channel through the bearing hole.

Preferably, a sealing element, in particular an O-ring, is arranged between the bearing part and the bearing bore. The sealing element serves to ensure that flushing water cannot escape via the bearing hole.

The sealing element also makes it possible to increase the friction between the bearing bore and the bearing part, with the advantages of: the position of the throttle element which is adjusted is kept constant.

Preferably, a stop element is provided between the throttling element and the pipe piece. Wherein the stop element has a regular spacing so that the throttle element can be controllably adjusted according to the spacing.

The stop element is preferably arranged between the support part and the support opening. Particularly preferably, the stop element is located outside the channel. Preferably, the stop elements are arranged in 30 ° or 45 ° increments around the axis of rotation. The increments can also be divided more finely.

Preferably, the restriction element has another bearing part opposite the drive part. Preferably, the duct element comprises a receptacle in its wall, wherein the support element protrudes into the receptacle. The receiving portion is preferably a recess in the side wall extending outwardly from the channel.

Preferably, the receptacle is located opposite the bearing hole of the channel.

The throttling element preferably comprises a carrier part, the geometry of which is transformable from an original state into an installed state during installation of the throttling element in the duct piece, and which, after complete installation of the throttling element in the duct piece, is transformed back into an original state in which the throttling element can no longer be detached from the duct piece. "not detachable again" is understood herein to mean: the throttling element cannot be removed without damage or by hand.

The bracket member preferably has the shape of two spring ears projecting from the planar area. The spring eye is compressed when inserted into the channel and then returns to the original state again. In this initial state, the maximum distance between the spring lugs is greater than the diameter of the bearing bore.

The distance between the inlet opening into the collecting reservoir and the throttle element along the passage is preferably at most 70 cm, particularly preferably at most 35 cm. This ensures that the flushing water can be throttled within a useful range. It is particularly preferred that no throttling element is provided in the flushing tank.

In a second embodiment, which is used alternatively to the above-described throttling element, the throttling element is a flexible part (ein flexipler Abschnitt) arranged in the pipe piece with a pipe platen (ein rohrschnelle) extending around it, wherein the cross-section of the flexible part can be varied by means of the pipe platen.

The sanitary product preferably has a contact opening for actuating the throttle element. For example, the contact openings may be provided in the side walls. Alternatively, the throttle element is arranged bare behind the rear edge of the collecting basin with respect to the collecting basin. In the alternative, the throttling element is preferably located outside the sanitary product. In the installed state, in the alternative, the throttle element can be located, for example, behind the front wall or behind the receptacle frame, so that it can then be adjusted, for example, before the front wall is finally installed or by passing through the access opening.

The collecting basin for the hygiene products is preferably constructed without a flushing edge. That is, the collection pool does not have a extended edge in the edge region.

The sanitary product arrangement preferably further comprises a flushing tank as a flushing water source, which is in fluid connection with the line piece directly or indirectly via an intermediate pipe, wherein the adjustment of the throttling element can be carried out without dismantling the flushing tank.

The throttling element is thus located between the flushing tank and the inlet. It is however particularly preferred that the throttling element is not part of the flushing tank.

The method of installation and fluid conditioning of a sanitary product unit as described above, characterised in that,

in a first step the sanitary product arrangement is connected fluidically, in particular via a pipe piece, to a flushing water source and via a discharge opening to a waste water network,

in a second step, a rinsing test is carried out during which the effect of the rinsing water in the collecting sump is observed and

the throttling element is adjusted in a third step as a function of the flushing test and its effect in the collection sump.

Preferably, the first step also comprises mechanically mounting the hygiene product in the space. For example a mechanical connection to a wall or bottom or mounting frame.

If the results are not satisfactory, the second step and, if necessary, the third step can be repeated.

Further embodiments are set out in the dependent claims.

Detailed Description

In fig. 1 a sanitary product arrangement 1 according to one embodiment of the invention is shown. The sanitary product arrangement 1 comprises a sanitary product 2 and a pipe piece 6, here known as an injection trap, through which flushing water can be injected into the sanitary product 2.

The sanitary product 2, which is shown here in the form of a toilet, has a collecting basin 3, an inlet 4 into the collecting basin 3 and an outlet 5 leading out of the collecting basin 3. A conduit member 6 is fluidly connected to the inlet 4. The tunnel element 6 is arranged here in the rear region of the sanitary product 2.

The tunnel 6 comprises a channel 7 surrounded by a wall 8. Furthermore, a throttle element 9 is provided, by means of which the cross section of the channel 7 for controlling the rinsing water can be varied. The line piece 6 can be connected to a flushing water source, not shown here. The source of flushing water may be a flush tank.

The restriction element 9 is arranged in the sanitary product 2 in such a way that the restriction element 9 is adjustable in a state in which it is in fluid connection with a source of flushing water. "capable of regulation" is understood to mean: the throttling element 9 is adjusted by the installer and is then secured substantially in its adjusted position throughout the life of the device. By means of a corresponding arrangement of the throttle element 9, it is not necessary or superfluous to remove the sanitary product 2 or the line piece 6 when adjusting the throttle element 9. Thereby, the installer can adjust the restriction element 9 after successful connection of the sanitary product 2 to the flushing water supply.

The sanitary product arrangement 1 according to the embodiment shown in the figures further comprises a mounting bracket 22 by means of which the sanitary product arrangement 1 can be fixed to a mounting frame or wall, not shown here. Instead of the mounting bracket 22, other fastening means can also be provided.

It can be well recognized from fig. 1 and 2 that: the throttling element 9 is arranged bare behind the rear edge 21 of the sanitary product 2. The throttle element 9 is thus exposed and not covered by the sanitary product 2. In the installed state, the throttle element 9 is located in the illustrated configuration in the region of the mounting bracket 22, for example with a removable cover in front of the front wall, and is accessible to the installer by passing through this cover when installing. In an alternative embodiment, which is not shown in the figures, the sanitary product can, for example, have a contact opening, wherein the throttle element 9 is arranged behind the contact opening.

In fig. 2, a further perspective view of the sanitary product arrangement 1 is shown. The throttle element 9 is shown here before being mounted to the duct element 6.

From fig. 1 and 2 it can also be identified that: the toilet 2 shown here relates to what is known as a flush-rim toilet. That is to say that no edge projecting into the collecting sump 3 is provided in the upper region 23 of the collecting sump 3. It is important in this type of toilet to regulate the flushing water circulation, since it is necessary to prevent the flushing water from splashing upwards above the upper area 23.

For the purpose of conveying the rinsing water into the collection sump 3, the inlet 4 opens tangentially into the surface of the collection sump 3 and generates a rinsing effect, preferably in the form of a rinsing vortex, in the collection sump 3. In this way, during rinsing, water is injected into the collecting basin 3 via the opening region 24 at the end of the inlet 4, in which the above-described rinsing effect occurs. The flushing water is then discharged from the collecting basin 3 via an outlet 5 located at the bottom of the collecting basin 3. The outlet 5 may also comprise a siphon.

In fig. 3 a partial cross-sectional view of the sanitary product arrangement 1 is shown. In this case, it can be well recognized that: the pipe element 6 projects into the inlet 4. A sealant or sealing/adhesive is preferably provided at the junction 25 between the inlet 4 and the pipe member 6 to form a sealing connection between the inlet 4 and the pipe member 6 that is impermeable to flushing water.

The channel 7 of the duct element 6 extends from a channel inlet 26 to a channel outlet 27. The channel outlet 27 here forms part of the junction 25, while a flushing water source is fluidly connected at the channel inlet 26. Between the channel inlet 26 and the channel outlet 27 a throttle element 9 is arranged, by means of which the flushing water flow in the channel 7 can be controlled.

From fig. 3 it can also be well recognized that: the outlet 5 of the sanitary product 2 opens into a siphon 28. A connecting sleeve 35, which can then be connected to the waste water network, is connected to the siphon 28.

In the embodiment shown, the duct element 6 is constructed separately from the sanitary product 2 and is connected thereto by means of a joint 25. Alternatively, the line piece 6 can also be an integral component of the sanitary product 2.

According to fig. 4 and 5, a preferred embodiment of a pipe piece 6 with a throttling element 9 is described here.

The throttle element 9 comprises a throttle part 10 and a drive part 11. The throttle element 10 projects into the passage 7 and the drive element 11 projects beyond the pipe element 6, so that the drive element 11 is accessible from outside the passage 7. The throttle element 10 is configured in the exemplary embodiment shown to be rotatable in the passage 4 about the axis of rotation S. The throttle element 10 can thereby change the cross section of the passage 7 correspondingly in its range of action when it is rotated about the axis of rotation S.

The drive member 11 comprises a receptacle 12 for receiving a tool. The receptacle 12 is designed as a slot, so that it can receive a screwdriver. When the screwdriver is rotated, the throttle element 9 can be turned around the rotation axis S. Other configurations of the drive element 11 are also conceivable. In an alternative embodiment, the drive member 11 may comprise a drive element which can be grasped, for example, by hand. Here, for example, a wing called a wing nut.

The throttle member 10 as shown in the drawings comprises at least one planar area 13. Two planar regions 13 are provided here, each lying in the same plane as the axis of rotation S. At the same time, the two planar areas 13 can be rotated about the axis of rotation S, thereby effecting the described cross-sectional change of the channel 7.

Between the drive member 11 and the throttle member 10, the throttle element 9 also comprises a bearing member 14. The wall 8 of the tunnel element 6 comprises a bearing bore 15 in which the throttling element 9 is supported by means of a bearing part 14. During the adjustment of the throttle element 9, the bearing part 14 is rotated about the axis of rotation S in the bearing bore 15.

The support member 14 and the support hole 15 are generally cylindrical in shape extending around the rotation axis S. The diameter of the bearing bore 15 is slightly larger than the longest extent of the throttle element 10 viewed transversely to the axis of rotation S, so that the throttle element 9 can be inserted into the channel 7 through the bearing bore 15.

A part of the drive part 11 extends at right angles to the axis of rotation S through the bearing opening 15 to the outside and thus forms a projecting shoulder.

The drive member 11 may also comprise a mark 32,. Wherein the indicia 32 indicate to the installer the orientation of the choke member 10 in the passageway.

In the illustrated embodiment, the support aperture 15 includes a shoulder 29 that provides a stop for the support member 14.

A sealing element 16 is preferably arranged between the bearing part 14 and the bearing bore 15. In the illustrated embodiment, the sealing element 16 is an O-ring. Although other sealing elements can be provided. Here, the O-ring is located in the gap 30 between the support member 14 and the side wall 31 of the support hole 15.

Particularly preferably, a stop element 17 is provided between the throttle element 9 and the line piece 6. In the embodiment shown, a retaining groove is provided outside the bearing bore 15 and a retaining web is provided around the region of the bearing part 14 of the throttle element 9. The distribution of the stop elements 17 around the circumference of the rotation axis S is preferably regular so that the installer can adjust the rotational position of the throttling element in predefined increments.

As shown in fig. 4, the throttle element 9 has a further bearing part 18 opposite the drive part 11, i.e. connected to the throttle part 10. The further bearing part 18 is designed here as a bearing pin. Wherein the duct element 6 comprises a receiving portion 19 provided by the wall portion 8. The support part 18 projects into the receptacle 19. The further bearing part 18 and the receptacle 19 form a pair of bearings, so that the throttle element 9 is not displaced during flow through.

Viewed from the channel 7, the receptacle 19 is opposite the bearing opening 15 and the axis of rotation S extends concentrically through the receptacle 19. The support part 18 is cylindrical in shape and extends around the circumference of the axis of rotation S.

The support member 18 is directly connected to the choke member 10.

The throttling element 9 further comprises a carrier member 20. When the throttle element 9 is set, the geometry of the carrier part 20 is deformed from the initial state into the installed state by the bearing bore 15. After the throttling element 9 has been completely installed in the duct element 6, the carrier part 20 is then returned to the original state again, as shown in fig. 4. Under this original shape, the extent of the bracket member 20 is larger than the cross section of the support hole 15 so as to make it impossible to detach. In the illustrated embodiment, the bracket member 20 includes two spring ears 33 protruding from the choke member 10. The spring lug 33 is configured in an elastic manner opposite the pivot S and, when inserted, is compressed in the installed state against the pivot S and then springs back again in the inserted state against the pivot S. The spring eye 33 is oriented in the same plane as the planar area 13 and therefore also forms part of the throttle element 10.

The distance of the channel 7 from the inlet 4, in particular from the junction 25, up to the throttle element 9 is preferably at most 40 cm, in particular at most 35 cm. The distance is here the length of the passage between the inlet 4 and the throttle element 9.

In the embodiment shown, the pipe piece 6 has the shape of an injection bend, wherein the throttling element 9 is arranged in a sub-region of the pipe piece running along a straight line.

From fig. 5 it can also be identified: the line piece 6 has an optional additional part 34 in the exemplary embodiment shown, which opens partially into the channel 7. A ventilation device, for example, can be connected to this.

The cross-sections of the channel inlet 26 and the channel outlet 27 can also be well identified from fig. 5. The passage inlet 26 has a cylindrical shape and is configured as a connection sleeve. The passage outlet 27 has an oval shape corresponding to the shape of the inlet 4 in the region of the junction 25.

The sanitary product arrangement 1 further comprises a flushing tank as a source of flushing water. The flushing tank is not shown here. The flush tank can be in fluid connection with the pipe piece 6 directly or indirectly via an intermediate pipe. Said adjustment of the throttling element 9 can thus be carried out without disassembling the flushing tank.

In the installation and fluid conditioning method of the sanitary product unit 1 described in the present invention, the sanitary product unit 1 is in a first step fluidly connected to a flushing water source via a plumbing member 6. The outlet 5 is also connected to the waste water network in the first step.

In a second step, a rinsing test is carried out, during which the effect of the rinsing water in the collecting sump is observed.

In a third step, the throttle element is adjusted according to the flushing test and its effect in the collection sump.

If the water distribution in the collection basin 3 is not satisfactory, the second step and, if necessary, the third step are subsequently repeated again.
