The present invention refers to a centralized device for the distribution and regulation of sanitary water with voice assistant, in accordance with the preamble of claim 1. In particular, an innovative centralized device is described, for the distribution and regulation of sanitary water at a desired temperature and flow rate, with the peculiarity of being able to control each user via a voice or remote command, for domestic and public plumbing and sanitary applications.

A water system has the function of distributing hot and cold water for sanitary use, from the main intake point to each delivery point in a house, and to remove it once used; it consists of a system of pipes, networks and components that make up the arteries of each building, capable of transporting and distributing water in the domestic, industrial or public fields, etc., or rather water used every day in a kitchen or a bathroom, and therefore for civil and industrial users.

The distribution network of a sanitary water system is composed of different types of pipes and elements: from the pipes located at the base of the building (in the basements or on the ground floor), the water is channelled through vertical pipes (the vertical risers) to then reach the floors or environments; this process takes place through the horizontal pipes of the respective interiors, towards the various sanitary appliances (sink, bathtub, shower, etc.) and the respective dispensing devices, or the terminals of the distribution network. It is known that collector water systems are now used for the distribution of water inside the pipes of the water system: their structure is composed of one or two pipes, made of materials such as brass, polypropylene, steel, etc. The construction of a collector water system involves the laying of pipes in parallel, each of which connects the main pipeline with the various water supply points. Upstream of each user there is an interception cock designed to exclude each single pipe in the event of a failure. Each cold and hot water duct is then connected to mechanical mixers for opening and mixing it: in this way, the creation of joints along the entire length of the pipe is avoided, reducing the risk of leaks under the floor.

Currently, collector water systems always provide for distribution via two pipes: one for hot water and one for cold water.

Many centralized devices for the distribution and regulation of sanitary water are known in the art, such as for example document CN210155564 relating to a thermos-regulator with voice control used to regulate the temperature of rooms of a house, or document KR10-1933672 which describes a method for adjust the temperature of rooms and of water distributors by means of a voice control or remotely via smartphone, with the help of an IoT interface that manages the solenoid valves, and also document W02009/019731 concerning an electronic device for mixing water and regulating a flow rate for single-pipe hydraulic systems for sanitary water.

The main prior art disadvantage concerns sanitary water distribution and regulation systems not able to use all water devices, separately or simultaneously, without the aid of the hands, and therefore by voice command and/or through applications for the remote control. Furthermore, these are devices without a control capable of closing the system distribution taps, interrupting the pressure to users in case of inactivity, to the advantage of a lower risk of flooding.

Documents FR-A1-2494806, US-A1-2021/203520 and WO-A1-8503764 disclose devices according to the preamble of Claim 1.

Object of the present invention is solving the aforementioned prior art problems by providing a centralized device for the distribution and regulation of domestic hot water with voice assistant, through a mechanical, technological and innovative solution with a mixing system upstream of the distribution users of the water, and with a revolutionary voice and/or remote control system, which will allow using all water devices, separately or simultaneously, without the aid of one's hands.

The device of the present invention is made in such a way that each user is independent, and allows the supply of hot, cold and mixed water at the desired temperature and flow rate by means of a simple voice command or by means of a dedicated application for the control from remote.

Another object is making it easier for people with disabilities to use this device, as well as to reduce the risk of contact infections in public and/or industrial environments.
