Description

Object of the invention

[0001] The present invention refers to a thermostatic fitting for bath/shower that comprises three separate modules, intake module, mixing module and distribution module, connected to each other via piping sectors to distribute mixed water towards at least two outlets, with the particularity that this thermostatic fitting is presented in a container that acts as packaging, allowing very easy embedded mounting in the wall, in a horizontal or vertical position, given that the masonry opening is reduced considerably, and the packaging is another of the construction elements.

[0002] Once the container is embedded, the thermostatic fitting easily remains flush and level with the wall, which makes it possible, given that the modules are separate, for the front of the container to be tiled, with a decorative covering in between the modules, providing a very different aesthetic and practical option that has not been possible hitherto, as trim plates of a considerable size have had to be used to conceal the masonry opening.

[0003] The different modules are concealed by inserting the corresponding caps and knobs which fit snugly on the decorative or tiled surface.

Background of the invention

[0004] In the state of the art embedded thermostatic fittings are known, being configured by a casing in which all of the tap elements are integrated, forming a main central block that includes the mixer together with the check valves and the filters, causing a series of drawbacks such as, for example, a masonry opening that necessarily has to be hidden by fitting trim plates of a considerable size to conceal the masonry opening.

[0005] Another drawback is the limited accessibility for maintenance or repair of check valves and filters.

[0006] In the quest for other solutions, patent ES2524022 presents a perfected unit for dispensing mixed water in which the said unit is partially embedded in the wall, being connected to the exterior part via telescopic sections, forming a two-knob unit, technically far-removed from a thermostatic fitting.

Description of the invention

[0007] The bath/shower thermostatic fitting for embedding seeks to eliminate the aforementioned problems by means of a modular configuration that permits diverse embodiments, to distribute mixed water towards at least two outlets.

[0008] In a preferred embodiment, the thermostatic fitting is configured to distribute mixed water towards a shower column/head or towards a shower hose and comprises three separate modules, an intake module, a mixing module and a distribution module, connected with each other via piping sectors which, in addition to maintaining the connection between the modules, brace the structure of the thermostatic fitting, the said thermostatic fitting being inserted in a container, which, in addition to acting as packaging, serves to facilitate joint embedded installation in a considerably reduced masonry opening.

[0009] The intake module comprises a casing with an inlet connection for cold water and another inlet connection for hot water, including inside it, check valves with filter, an outlet chamber for cold water, an outlet chamber for hot water and an inlet chamber for mixed water, the said chamber being connected, with a conduit positioned on the front of the said intake module.

[0010] The inlet chamber for mixed water is not used in this embodiment and therefore remains sealed with a plug, so the conduit located on the front of the intake module remains unused, as it is not utilised in this embodiment.

[0011] The intake module incorporates, on its upper part, an insertion coupling envisaged for attaching a covering cap that conceals and protects the check valves with filter.

[0012] It is important to note the different possible options that the configuration of the intake module offers, since the inlet chamber for mixed water can be enabled in any other alternative embodiment, allowing a different combination with the other modules included in the thermostatic fitting.

[0013] A characteristic of the invention is the separation of the check valves with filter from the thermostatic mixer cartridge, this way configuring, a separate module to contain the check valves and their corresponding filters, with the advantage that it permits access to them, for cleaning or replacement, by simply removing the covering cap, which is fixed and does not have actuating functions, although it does have piping functions in an alternative embodiment.

[0014] The mixing module comprises a casing that includes, inside it, a thermostatic mixer cartridge and other functional elements intended to regulate the temperature of the water; the said casing includes a cold water inlet chamber, a hot water inlet chamber and a mixed water outlet chamber and, on its lower part, a through hole.

[0015] The through hole is intended for attaching a piping sector used in an alternative embodiment.

[0016] The mixing module incorporates, on its upper part, an insert coupling for the attachment of a control knob intended for water temperature control. The said control knob incorporates a temperature indicating scale supplement, or optimal usage temperature indicator, since it can be rotated so as to position it at the point of comfort point of the user's choice.

[0017] The mixing module is of a small size, similar to the adjacent modules, thanks to the check valves with filter being separate; it is characteristic of the invention that the said elements are incorporated in a separate module, in this case, the intake module.

[0018] The distribution module comprises a casing configured with at least two outlet connections to divert the mixed water towards the shower column/head or towards a bath or shower hose, the said casing comprising an inlet chamber for mixed water.

[0019] The casing of the distribution module also comprises a chamber that is envisaged for the return of mixed water and an evacuation conduit positioned on the front of the said module, which, in this preferred embodiment, are sealed by insertion of a plug, ready to be used in other alternative embodiments.

[0020] The distribution module includes, on its upper part, an insert coupling to attach an actuating knob intended to divert the mixed water towards the shower column/head or towards a bath or a shower hose, simultaneously controlling the water flow by the gradual actuation of the actuating knob.

[0021] In a preferred embodiment, watertight connection between the intake, mixing and distribution modules is carried out via the following piping sectors:
Cold water piping sector, that connects the cold water outlet chamber of the intake module with the cold water inlet chamber of the mixing module.

[0022] Hot water piping sector, that connects the hot water outlet chamber of the intake module with the hot water inlet chamber of the mixing module.

[0023] Mixed water piping sector, that connects the mixed water outlet chamber of the mixing module with the mixed water inlet chamber of the distribution module.

[0024] The special configuration of the thermostatic fitting modules is characteristic of the invention as they comprise different chambers intended for inlet and outlet of cold, hot and mixed water, with the aim of being able to configure different embodiments when combining them.

[0025] The container, that acts as packaging, is made of a very strong, lightweight material and includes cavities intended for positioning the three modules, connected to each other via their different piping sectors, and a front finish, coinciding with the cap and knobs of the aforementioned thermostatic fitting, which allows it to be tiled over.

[0026] Thus, the container is a constructive unit that considerably facilitates the embedded mounting of the thermostatic fitting which, thanks to the reduction in the masonry opening, eliminates the use of large trim plates, since only the cap and the knobs of the different modules are necessary.

[0027] Once the container is embedded, the thermostatic fitting easily remains flush and level with the wall, which makes it possible, given that the modules are separate, for the front of the container to be tiled, with a decorative covering in between the modules, providing a very different aesthetic and practical option that has not been possible hitherto, as trim plates of a considerable size have had to be used to conceal the masonry opening.

[0028] After the front of the container has been covered or tiled, the insertion couplings of the modules, envisaged for the attachment of the corresponding caps and knobs, remain visible, with the particularity that an intermediate element has been envisaged for insertion between them, allowing to adjust for or to absorb possible construction gaps between the thermostatic fitting and the mortar plus tile; in this way both the caps and the knobs fit snugly on the tile surface or decorative covering.

[0029] It is important to point out that the packaging is used as another constructive element, avoiding the generation of waste, to the benefit of the environment.

[0030] In an alternative embodiment the thermostatic fitting is configured to distribute mixed water towards a shower column/head or towards a shower hose, positioned in this case, on the covering cap of the intake module, and comprising a modular structure similar to the preferred embodiment but suitable for an additional function.

[0031] In this alternative embodiment the inlet chamber for mixed water of the intake module is enabled by removing the sealing plug and inserting a connecting tube in the conduit positioned on the front of the said module.

[0032] The intake module incorporates a covering cap that, in addition to concealing and protecting the check valves with filter, comprises an attachment support for the attachment of the handle of a shower hose and the corresponding water intake connection, the said intake connection being connected to the connecting tube to divert the water towards the shower hose, incorporated in the said covering cap.

[0033] Two outlets are used on the distribution module, one to divert the mixed water towards a shower column/head via its corresponding outlet connections and another outlet to divert the mixed water towards a shower hose, situated on the covering cap of the intake module, in this case by enabling the mixed water return chamber, by removing the sealing plug.

[0034] In this alternative embodiment the line corresponding to the outlet connection to divert the mixed water towards the bath is sealed by means of a plug.

[0035] The actuating knob of the distribution module diverts the mixed water towards the shower column/head or towards a shower hose situated on the covering cap of the intake module, simultaneously controlling the water flow by gradual actuation of the knob.

[0036] The watertight connection of the piping sectors, between the intake, mixing and distribution modules, is the same as that described in the preferred embodiment and also incorporates a mixed water return piping sector which connects the mixed water return chamber of the distribution module to the mixed water inlet chamber of the intake module, the mixed water return piping sector fitting snugly in the through hole of the mixing module.

[0037] It is important to note that, via the mixed water return piping, the mixed water is distributed for its use in an additional shower hose.

[0038] In another alternative embodiment, the thermostatic fitting is configured with three outlets to distribute the mixed water towards a shower column/head or towards a bath or towards a shower hose, positioned at a certain distance from the thermostatic fitting, comprising a modular structure similar to the preferred embodiment but suitable for an additional function.

[0039] In this alternative embodiment, the distribution module is configured with three outlet connections, one for each function, to distribute the mixed water towards the shower column/head or towards a bath or towards a shower hose, located at a certain distance from the thermostatic fitting, depending on the construction configuration of the bath.

[0040] In this alternative embodiment, the chamber envisaged for the return of mixed water and an evacuation conduit, positioned on the front of the said module, are sealed by insertion of a plug, ready to be used in other alternative embodiments.

[0041] Likewise, the mixed water inlet chamber of the intake module is also sealed by means of a plug as it is not used in this alternative embodiment.

[0042] The watertight connection of the piping sectors, between the intake module, mixing module and distribution module is exactly the same as that described in the preferred embodiment.

[0043] In another alternative embodiment the thermostatic fitting is configured to distribute the mixed water towards a shower column/head or towards a shower hose, positioned in this case, on the covering cap of the intake module, comprising a modular structure similar to the previous alternative embodiment, but suitable for an additional function.

[0044] In this alternative embodiment the inlet chamber for mixed water of the intake module is enabled by removing the sealing plug and inserting a connecting tube in the conduit positioned on the front of the said module.

[0045] The intake module incorporates a covering cap that, in addition to concealing and protecting the check valves with filter, comprises an attachment support for the attachment of the handle of a shower hose and the corresponding water inlet connection, the said inlet connection being connected to the connecting tube to divert the water towards the shower hose, incorporated in the said covering cap.

[0046] The distribution module is configured with three outlet connections, one to divert the mixed water towards a shower column/head, another to divert the water towards a bath, while the outlet connection to divert the mixed water towards a shower hose or bath remains sealed by means of a plug.

[0047] In this alternative embodiment the mixed water return chamber is enabled by removing the sealing plug to divert the mixed water towards a shower hose, positioned on the covering cap of the intake module.

[0048] The actuating knob of the distribution module diverts the mixed water towards the shower column/head or towards a bath or towards the shower hose positioned on the covering cap of the intake module, simultaneously controlling the water flow by gradual actuation of the knob.

[0049] The watertight connection of the piping sectors, between the intake, mixing and distribution modules, is the same as that described in the preferred embodiment and also incorporates a mixed water return piping sector which connects the mixed water return chamber of the distribution module to the mixed water inlet chamber of the intake module, the mixed water return piping sector fitting snugly in the through hole of the mixing module.

[0050] It is important to note that, via the mixed water return piping, the mixed water is distributed for its use in an additional shower hose.

[0051] In another alternative embodiment, a drain device is incorporated, which comprises a drainage line, also incorporating a connecting tube, the said device being positioned between the distribution module, in any of the described embodiments, and the actuating knob.

[0052] The evacuation conduit of the distribution module is enabled in this embodiment by removing the sealing plug, for the insertion of the connecting tube supplied in the drain device, the evacuation conduit of the distribution module being connected to the drainage line to the exterior, of the drain device, allowing drainage of water retained in the shower column/head to the exterior, by means of the closed positioning of the actuating knob of the distribution module.

[0053] Although orifices or pipes especially intended for draining water retained in water piping are already known in the state of the art, in this the invention an innovative separate drain supplement is advocated, which is optionally included in a thermostatic fitting of an embedded nature.

[0054] In another alternative embodiment the structure of the thermostatic fitting is reinforced by means of longitudinal securing ties that pass through the intake, mixing and distribution modules, bracing the unit, the ends of the said ties being secured by locking means.

[0055] It is important to highlight the function of the said ties, which, together with the piping sectors strengthen the structure of the thermostatic fitting, in any of the described embodiments.

Advantages of the invention

[0056] This thermostatic fitting for embedding that is presented affords numerous advantages over those currently available, the main advantage being that it is configured with three separate modules, the intake module, mixing module and distribution module, connected to each other via piping sectors, inserted in a container which, in addition to being used as packaging, facilitates the execution of embedding the thermostatic fitting.

[0057] An important added advantage is that once the thermostatic fitting is embedded in the masonry opening, it easily remains flush and level with the wall, making it possible, given that the modules are separate, for the front of the container to be tiled, with decorative covering in between the modules, providing a very different aesthetic and practical option that has not been possible hitherto, as trim plates of a considerable size have had to be used until now.

[0058] An important advantage, as a result of the previous one, is that once the covering or tiling over the front of the container has been carried out, the module couplings, intended for the insertion of the corresponding caps and knobs, remain visible, with the particularity that the insertion of an intermediate element between them has been envisaged, allowing to adjust for possible construction gaps between the thermostatic fitting and the mortar plus tile.

[0059] Another important advantage is that the check valves with filter are separate from the thermostatic mixing cartridge, being integrated in an intake module, thus allowing the dimensions of the different modules to be reduced to facilitate their embedded installation, this way reducing the masonry opening.

[0060] Another advantage arises as a consequence of the reduction of the masonry opening, which allows the elimination of the trim plates that are commonly used in this type of mounting, replacing them with the covering cap and knobs of the different modules.

[0061] An added advantage is that, in an alternative embodiment, the thermostatic fitting incorporates and additional connection for a shower hose, positioned on the fitting itself or separate from it.

[0062] A further added advantage is the possibility of incorporating a drain supplement on the thermostatic fitting.

[0063] And finally, an added advantage is that, in addition to the piping sectors that maintain the structural stiffness of the thermostatic fitting, the said structure is reinforced by incorporating longitudinal ties.

Preferred embodiment of the invention

[0065] The conformation and characteristics of the invention can be better understood in the following description that relates to the attached figures.

[0066] Figure 1 shows the thermostatic fitting (1) in a preferred embodiment, configured with two outlets to distribute the mixed water towards a shower column/head (2) or towards a shower hose (4).

[0067] The thermostatic fitting (1) is shown housed in a container (8) which in turn acts as packaging and as a construction element since the embedded installation of the thermostatic fitting (1) is carried out jointly with the said container (8).

[0068] The covering cap (14) for attaching on the intake module (5) is shown, as is the control knob (16) with the temperature indicating scale supplement (17) or optimal usage temperature indicator, for attaching on the mixing module (6) and the actuating knob (21) for attach on the distributing module (7), controlling the water flow gradually, the said knobs and cap being secured onto the said controls by an insertion coupling (13) integrated in the said modules.

[0069] The container (8), given that it remains flush with the wall, makes it possible, since that the intake module (5), mixing module (6) and distribution module (7) are separate, as shown in figure 1, for the front of the container (8) to be tiled, with a decorative covering between the modules, providing a very different aesthetic and practical option that has not been possible hitherto, as until now trim plates of a considerable size have had to be used.

[0070] Figure 2 shows the modular structure of the thermostatic fitting (1), showing the separate intake module (5), the mixing module (6) and the distribution module (7), connected to each other via piping sectors, also showing securing longitudinal ties (32) that, by passing through the intake (5), mixing (6) and distribution (7) modules, brace the unit, the ends of the said ties being secured by locking means (33).

[0071] The intake module (5) is shown, which comprises a casing with two inlets, one for cold water (9) and another for hot water (10), including inside it the check valves (11) with filter, incorporating on its upper part two outlet piping sectors, one for cold water (22) and, very close by and parallelly positioned, another for hot water (23), being connected to the mixing module (6) by watertight connecting means.

[0072] The intake module comprises a casing with an inlet connection for cold water (9) and another inlet connection for hot water (10), including inside it, the check valves (11) with filter, an outlet chamber for cold water, an outlet chamber for hot water and an inlet chamber for mixed water (not shown), the said chamber being connected, with a conduit (12) positioned on the front of the said intake module (5).

[0073] The intake module (5) contains the check valves (11) and their corresponding filters, with the advantage that they can be accessed for cleaning or replacement by simply removing the covering cap (14), which is fixed and does not have actuating functions.

[0074] The mixing module (6) comprises a casing that includes, inside it, a thermostatic mixer cartridge and other functional elements (not shown) intended to regulate the temperature of the water; the said casing includes a cold water inlet chamber, a hot water inlet chamber and a mixed water outlet chamber (not shown) and, on its lower part, a through hole (15).

[0075] The mixing module (6) is configured in a small size, similar to the adjacent modules, thanks to the separation of the check valves (11) with filter, since it is a characteristic of the invention that the said elements are incorporated in a separate module, in this case, in the intake module (5).

[0076] The distribution module (7) is illustrated, showing a casing configured with at least two outlet connections (18) to divert the mixed water towards the shower column/head (2) or towards a bath (3) or shower hose (4), the said casing comprising an inlet chamber for mixed water (not shown).

[0077] The casing of the distribution module (7) also comprises a chamber that is envisaged for the return of the mixed water and an evacuation conduit (19), positioned on the front of the said module, which, in this preferred embodiment, are sealed by insertion of a plug (20), ready to be used in other alternative embodiments.

[0078] The watertight connection between the intake (5), mixing (6) and distribution (7) modules, shown in figures 1, 2 and 3, is carried out via the following piping sectors:
Cold water piping sector (22), that connects the cold water outlet chamber of the intake module (5) with the cold water inlet chamber of the mixing module (6).

[0079] Hot water piping sector (23), that connects the hot water outlet chamber of the intake module (5) with the hot water inlet chamber of the mixing module (6).

[0080] Mixed water piping sector (24), that connects the mixed water outlet chamber of the mixing module (6) with the mixed water inlet chamber of the distribution module (7).

[0081] Figure 3 shows the connection between the different modules, viewed from the rear, indicating
the sealing of the mixed water return chamber, distribution module (7); the mixed water inlet chamber of the intake module (5) also being sealed in the same way, by means of plugs (20); the conduit (12) positioned on the front of the intake module (5), remaining unused as it is not utilised in this preferred embodiment.

[0082] Figure 4 shows the container (4) which acts as packaging, made of very strong, lightweight material, indicating the cavities (25) intended for the positioning of the thermostatic fitting, in any of its embodiments. Thus, the container (4) is a constructive unit that considerably facilitates the embedded mounting of the thermostatic fitting, which thanks to its reduced dimensions, adjusted to the size of the fitting, considerably decreases the masonry opening, eliminating the use of trim plates, since only the covering caps (14 or 14.1) and the knobs (16 and 21) of the different modules are necessary.

[0083] Figure 5 schematically illustrates the installation of the thermostatic fitting (1) in a horizontal position, in a preferred embodiment in which the mixed water is diverted towards a shower column/head (2) or towards a shower hose (4), showing the inlet of cold water and hot water through the intake module (5), the inlet of hot water and cold water in the mixing module, via the cold water piping sector (22) and hot water piping sector (23), the mixed water passing towards the distribution module (7) via the mixed water piping sector (24), for its distribution, depending on the position of the actuating knob (21)

[0085] Figures 7 and 8 illustrate the thermostatic fitting (1.1) in an alternative embodiment, configured to distribute the mixed water towards a shower column/head (2) or towards a shower hose (4), positioned in this case, on the covering cap (14.1) of the intake module, comprising a modular structure similar to the preferred embodiment, but suitable for an additional function.

[0086] In this alternative embodiment the inlet chamber for mixed water of the intake module (5) is enabled by removing the sealing plug (20) and inserting a connecting tube (26) in the conduit (12) positioned on the front of the said module.

[0087] The intake module (5) is shown, which incorporates a covering cap (14.1) which, in addition to concealing and protecting the check valves (11) with filter, comprises an attachment support (30) for the attachment of the handle of a shower hose and the corresponding water inlet connection (31), the said inlet connection (31) being connected with the connecting tube (26) to divert the water towards the shower hose (4), incorporated in the said covering cap (14.1).

[0088] Figure 8 shows the distribution module (7) using two outlets, one to divert the mixed water towards a shower column/head (2), via its corresponding outlet connection (18), and another outlet to divert the mixed water towards a shower hose (4), positioned on the covering cap (14.1) of the intake module (5), in this case the mixed water return chamber (not shown) is enabled by removing the sealing plug (20), showing the outlet connection (18) to divert the mixed water towards the bath (3), sealed by a plug (20) since it is not utilised in this alternative embodiment.

[0089] The actuating knob (21) of the distribution module (7) is shown, being intended to divert the mixed water towards the shower hose (4) or towards the shower column/head (2), simultaneously controlling the water flow, since the gradual actuation of the actuating knob (11) allows the control of the said flow.

[0090] Furthermore, figures 7 and 8 show common elements such as, the container (8) of the mixing module (6), with its corresponding control knob (16) and temperature scale supplement (17), the outlet piping sectors, one for cold water (22) and the other for hot water (23), the mixed water inlet piping sector (24), also showing the longitudinal ties (32) for securing.

[0091] This alternative embodiment shows the incorporation of a mixed water return piping sector (27) that connects the mixed water return chamber of the distribution module (7) with the mixed water inlet chamber of the intake module (5), the mixed water return piping sector (27) fitting snugly in the through hole (15) of the mixing module (6).

[0092] Figure 9 schematically illustrates the installation of the thermostatic fitting (1.1) in a horizontal position, in an alternative embodiment in which the mixed water is diverted towards a shower column/head (2) or towards a shower hose (4), positioned on the water intake module (5), showing the inlet of cold water and hot water through the intake module (5), the inlet of hot water and cold water in the mixing module, via the cold water piping sector (22) and hot water piping sector (23), the mixed water passing towards the distribution module (7) via the mixed water piping sector (24), using, in this case, the mixed water return piping (27) towards the shower hose (4) for its distribution, depending on the position of the actuating knob (21)

[0093] Figures 10 and 11 illustrate the thermostatic fitting (1.2) in an alternative embodiment, configured with three outlets to distribute the mixed water towards a shower column/head (2) or towards a bath (3) or towards a shower hose (4), positioned at a certain distance from the thermostatic fitting (1.2), comprising a modular structure similar to the preferred embodiment, but suitable for an additional function.

[0094] The distribution module (7) is shown, configured with three outlet connections (18), one for each function, to distribute the mixed water towards the shower column/head (2) or towards a bath (3) or towards a shower hose (4), located at a certain distance from the thermostatic fitting (1.2.).

[0095] In this alternative embodiment, the chamber envisaged for the return of mixed water (not shown) and an evacuation conduit (19), positioned on the front of the said module, are sealed by the insertion of a plug (20), ready to be used in other alternative embodiments, the mixed water inlet chamber (not shown) of the intake module (5) remaining sealed by means of a plug (20).

[0096] The watertight connection of the piping sectors (22, 23 and 24), between the intake module (5), mixing module (6) and distribution module (7) is exactly the same as that described in the preferred embodiment, shown in figure 1.

[0097] Furthermore, figures 10 and 11 show common elements such as, the container (8), the mixing module (6) with its corresponding control knob (16) and temperature scale supplement (17), the outlet piping sectors, one for cold water (22) and the other for hot water (23), the mixed water inlet piping sector (24), also showing the longitudinal ties (32) for securing.

[0098] Figure 12 schematically illustrates the installation of the thermostatic fitting (1.2) in a horizontal position, in an alternative embodiment in which the mixed water is diverted towards a shower column/head (2) or towards a bath (3) or towards a shower hose (4), positioned at a certain distance from the thermostatic fitting (1.2), showing the inlet of cold water and hot water through the intake module (5), the inlet of hot water and cold water in the mixing module, via the cold water piping sector (22) and hot water piping sector (23), the mixed water passing towards the distribution module (7) via the mixed water piping sector (24), for its distribution depending on the position of the actuating knob (21).

[0099] Figures 13 and 14 illustrate the thermostatic fitting (1.3) in an alternative embodiment, configured to distribute the mixed water towards a shower column/head (2) or towards a bath (3) or towards a shower hose (4), positioned in this case, on the covering cap (14.1) of the intake module (5), comprising a modular structure similar to the preferred embodiment shown in figures 10 and 11, but suitable for an additional function.

[0100] In this alternative embodiment the inlet chamber for mixed water (not shown) of the intake module (5) is enabled by removing the sealing plug (20) and inserting a connecting tube (26) in the conduit (12) positioned on the front of the said module.
