Definitions

  • 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.
  • 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.
  • the different modules are concealed by inserting the corresponding caps and knobs which fit snugly on the decorative or tiled surface.
  • Another drawback is the limited accessibility for maintenance or repair of check valves and filters.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the through hole is intended for attaching a piping sector used in an alternative embodiment.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • thermostatic fitting modules are 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

  • 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.
  • the line corresponding to the outlet connection to divert the mixed water towards the bath is sealed by means of a plug.
