Description

BACKGROUND OF THE INVENTION

This invention relates to a device for selective delivery of one or more types of liquid, in particular hot water, cold water, mixed water and treated water, and provided with a fixing system for mounting on a wall.

PRIOR ART

Devices are known for delivering hot/cold/ mixed sanitary water and treated water, for example purified water with possible carbonation by carbon dioxide, which are fitted to a portion of a horizontal plane that is part of a sink or of a plane of a piece of kitchen furniture. In order to fit the above device, it is necessary to make appropriately one or more holes in the aforesaid portion of horizontal plane to enable the device to be connected to the hot and cold sanitary water conduits and to the supply pipe for the treated water connected to a filtration/refrigeration/carbonation unit located in the zone below the sink. In some cases and in certain circumstances, it is desired to avoid fitting the delivery device to the plane of the sink or kitchen, for aesthetic reasons, and because it is appropriate to avoid having to drill the horizontal plane or also for other needs. Nevertheless, currently, there are no solutions available that enable drilling or installation of the plane of the sink to be avoided unless, in a laborious, costly and also aesthetically displeasing manner, a mixer tap for the sanitary water is provided and a further distinct tap is provided that is dedicated only to delivering treated water.

Delivering devices are known from CN203309268, EP2884012, US1572412, EP0577164 and EP2975185.

OBJECTS OF THE INVENTION

One object of the present invention is to improve currently known delivery devices for delivering selectively hot/cold/mixed water and treated water, and in particular, provide a new solution that enables a multiple delivery device to be wall-mounted without the need to use additional taps for the treated water. Another object is to provide a delivery device solution that in addition to ensuring greater versatility and ease of use in the case of wall-mounted installation, also enables the general overall dimensions required in installation to be minimised.

SHORT DESCRIPTION OF THE INVENTION

The above is achieved by a delivery device according to what is defined in claim 1.
The new device according to the invention thus enables the aforesaid drawbacks to be overcome, and in addition to being versatile, compact and practical to use is also provided with a very pleasing aesthetic appearance.

DETAILED DESCRPTION OF THE UTILITY MODEL

With reference to the attached Figures, a delivery device 1 is shown that is in particular but in a non-limiting manner suitable for domestic use, is in particular suitable for being installed in a domestic kitchen, and suitable for delivering selectively in a desired manner several types of fluid, in particular hot sanitary water, cold sanitary water, hot and cold water mixed together and treated water. The treated water comprises purified water/filtered water, refrigerated water, water to which carbon dioxide has been added, etc. The delivery device 1 is configured internally for maintaining always separate from one another from the inlet to the outlet the flows of sanitary water and of treated/purified water, preventing the flows from coming into contact with one another.
The device 1 comprises a main body 2 that extends with a cylindrical or parallelpipedon shape or other desired geometrical shape along a longitudinal axis Y that in normal operation, i.e. after completed installation, is arranged horizontally. The delivery device 1 comprises a first mixer tap 3 coupled with a first end of the main body 2, provided internally with a suitable mixing cartridge, and suitable for enabling the delivery of hot/cold/thermally mixed sanitary water to be controlled. The delivery device 1 comprises a second tap 4 coupled with said main body 2, and suitable for delivering the treated water, the latter being supplied by a purification and/or refrigeration and/or water carbonation unit U.
To the main body 2 a dispensing hose 5 is connected movably, through which the various aforementioned types of liquid are delivered selectively. The dispensing hose 5 is rotatably adjustable with respect to the aforesaid main body 2 around a vertical axis X in such a manner as to enable, during normal operation, a user to direct the jet of water in a desired position.
The delivery device 1 is provided with connecting means 6, 7 for connecting the main body 2 to respective sources of hot sanitary water and of cold sanitary water. Advantageously, the connecting means 6, 7 is configured for enabling the main body 2 to be fixed to a desired vertical surface 9, such as in particular a wall. The connecting means 6, 7 extends along a plane P arranged transversely to said vertical axis X, in particular along a plane P arranged orthogonally to the aforesaid vertical axis X. In other words, the connecting means 6, 7, is configured for extending, during normal operation of the delivery device 1, horizontally.
The connecting means comprises a first connection 6 for supplying the hot water and a second connection 7 for supplying the cold water. The first connection 6 and the second connection 7 are distinct and separate from one another and extend according to respective axes A1, A2 which, in the installed operating configuration, are thus oriented orthogonally to a vertical plane, i.e. they are horizontal.
The first 6 and second 7 connections comprise respective seats into which suitable tubular portions of conduit are screwed for the passage of the respective hot and cold liquid. Such conduit portions are configured for being coupled, by suitable hexagonal nuts, with suitable threaded unions (for example eccentric threaded elements) that are fitted protruding from the respective pipes, on the wall 9, which convey the hot water and cold water of the domestic network. The first 6 and second 7 connections further comprise respective circular cover elements 22, which are discoidal or crown-shaped or have another desired shape, which are axially slidable along the tubular conduit portions 6, 7 and are suitable for performing a protective and aesthetic covering function in the joining zones that are made between the delivery device 1 and the wall 9.
In the main body 2 a first path 10 is defined internally for the hot water and a second path 11 is defined for the cold water, which paths extend from the respective zones from which the connections 6 and 7 lead, to enable the hot and cold water to flow to the first mixer tap 3. In the main body 2 a third path 12 is also defined for the mixed hot/cold water exiting said first mixer tap 3, and connecting the first mixer tap 3 to the dispensing hose 5.
As already mentioned, the first mixer tap 3, the second tap 4 and the internal channels dedicated respectively to the sanitary water (supplied by the water network) and to the treated/purified water (supplied by the purification and/or refrigeration and/or carbonation unit U), are configured for keeping the aforesaid different types of fluid separate from one another.
The delivery device 1 comprises further connecting means 8 for connecting the main body 2 to a source of treated water, in particular to the water carbonation and/or refrigeration and/or purification unit U.
The further connecting means, obtained on the main body 2, comprises a connection portion 8 that is distinct and separate from the first 6 and second 7 connections, and configured for being connected to a supply pipe connected to a unit U. According to the invention the connection 8 portion is provided on a rear zone of the main body (2) near the first connection 6, ; nevertheless, the connection portion 8 can be provided on other desired zones of the main body 2.
In the main body 2 a fourth path 13 is defined for the treated water, which places the connection 8 portion in fluid communication with the second tap 4 and the latter with the dispensing hose 5.
In the dispensing hose 5 a first delivery conduit 14 is defined for the cold/hot/mixed sanitary water exiting the first mixer tap 3, and second delivery conduit 15 is defined for the treated water exiting the second tap 4.
The first delivery conduit 14 and the second delivery conduit 15 are configured for keeping the respective fluids separate from one another that traverse the first delivery conduit 14 and second delivery conduit 15.
The first delivery conduit 14 and the second delivery conduit 15 extend along the dispensing hose 5 as far as a first outlet port 16 and a second outlet port 17 respectively. According to certain possible embodiments of a dispensing hose 5, the first delivery conduit 14 and the second delivery conduit 15 extend along the dispensing hose 5 in a mutually distinct and parallel manner. According to other possible embodiments, the first delivery conduit 14 and the second delivery conduit 15 extend coaxially to one another, with one of the aforesaid conduits 14 or 15 that extend inside the other conduit 15 or 14.
According to certain possible embodiments of device 1, shown in figures 1, 3, 4, the dispensing hose 5 is coupled with the main body 2 by a bush portion 18 that protrudes vertically upwards from an upper zone 19 of the main body 2.
According to other possible embodiments of the device shown in figures 2, 5-8, the dispensing hose 5 is coupled with the main body 2 by a bush portion 18 that protrudes vertically downwards from a lower zone 20 of the main body 2.
Owing to the particular structural configuration of the delivery device 1, in particular owing to the connecting means 6, 7, obtained with a lying configuration according to a horizontal plane on the main body 2, and owing to the further connecting means 8 incorporated into the aforesaid main body 2, it is possible to install the device 1 easily on a vertical wall or load-bearing wall of a kitchen, thus avoiding having to make undesired holes on the sink plane or kitchen plane, making it unnecessary to use an addition tap dedicated only to delivering treated water. Thus, with the present delivery device 1 provided with fixing system for wall mounting, the present objects are reached and the drawbacks stated above are overcome. All this is achieved thanks to a convenient, effective, versatile solution with compact dimensions with aesthetically pleasing geometrical shapes.
Further versions of and/or variations on what has been disclosed and illustrated in the attached drawings are possible.
Various elements can be replaced by further technically equivalent elements without thereby falling outside the scope of the invention.
It is possible to configure and dimension the delivery device 1 in the desired manner according to the particular application for which it is intended. Lastly, the materials used for the construction of the device 1 can be chosen according to need provided that they are suitable for the specific use for which they are intended. However, the scope of protection is solely defined by the appended claims.
