According to the invention, the wash unit sink 1 comprises a collection unit 11 which can be associated with the delivery unit 6, designed to intercept any leaks of washing liquid that may enter through the extraction opening 10.

More precisely, the collection unit 11 performs the function of collecting the washing liquid that can enter the extraction opening 10, mainly to prevent the liquid from dispersing on the floor, creating areas at risk of slipping, or in any case in areas underneath the washing station where the wash unit sink 1 is installed.

The collection unit 11 comprises a collection container 12 applied to the washing tank 2, in particular at the extraction opening 10, to collect the washing liquid coming out through the same extraction opening 10. The latter is positioned for example in correspondence with a raised area 13 of the washing tank 2.

The collection container 12 can, for example, have the shape of a containment cup. The collection container 12 can have a different shape, as described in more detail below.

The collection container 12 comprises, in particular, an inlet section 14a or inlet opening, through which the connecting tube 8 of the dispensing member 7 is able to be inserted. The collection container 12 can therefore be connected to the 'extraction opening 10 of the dispensing member 7, in correspondence with the inlet section 14a, in order to be able to extract through it, in a sliding manner, the connecting pipe 8 of the dispensing member 7. The collection container 12 also comprises a outlet section 14b or outlet opening, for the insertion of the connection pipe 8 at the outlet and therefore the connection to the interception and / or mixing device 5.

The outlet section 14b can be obtained at the base of the collection container 12. In this case, the collection container 12 preferably comprises a sealing member 15, housed in correspondence with the outlet section 14b, in order to safely seal the Sliding insertion area, at the outlet, of the connecting pipe 8. The sealing member 15 is preferably annular in shape, for example by forming an annular gasket of a known type, easy to apply at the outlet section 14b.

The collection container 12 advantageously also comprises an outflow section 16 or outflow opening, to allow the preferably controlled outflow of the collected liquid. Preferably, the outflow section 16, which can be located at the base of the collection container 12, is connected by means of a conveyor fitting 17 of a known type, preferably flexible, to the aforementioned discharge unit 9.

The outflow section 16 can, for example, form a portion of duct or branch, placed in communication with the base of the collection container 12.

Advantageously, the collection container 12 is associated with the extraction opening 10 by means of the interposition of a fixing member 18, in particular, of a coupling member of the type of a coupling ring.

Preferably, the ring nut fastening member 18 has an annular shape and provides one or more hooking tabs or flaps 19, suitable for engaging respective notches 20 made peripherally to the collection container 12, in correspondence with the inlet section 14a, to allow the stable coupling to the wash unit sink 1, in correspondence with the extraction opening 10. Preferably and advantageously, this coupling between the collection container 12 and the fixing member 18 is removable. Likewise, the fastening member 18 is preferably removable or disengageable from the extraction opening 10 of the tank 2, thus allowing both easy assembly and easy disassembly.

The washing tank 2 preferably comprises, in turn, a support sleeve 21 fixed at the extraction opening 10, through which the connection pipe 8 of the delivery unit 6 is removable. The fixing member 18 described above, then, can be advantageously applied to the support sleeve 21, preferably in a removable way, to firmly couple the collection unit 11 to the tank 2, at the extraction opening 10.

The collection unit 11 can also comprise a manifold fitting 22, for connection to the discharge unit 9 of the washing liquid from the tank 2. This manifold fitting 22 is made for example in the shape of a reducer duct 23 of suitable section, suitable for be fixed tightly to the drain 24 of the discharge unit 9 and placed in communication with the conveyor fitting 17. The provision of a collector fitting 22 serves to lead the liquid collected in the collection container 12 to a common outflow section, to carry out the drain together with the liquid coming from the tank 2.

The operation of the wash unit sink according to the invention is easily understood from the above description.

In a step prior to the use of the head wash sink 1, the collection unit 11 is applied to the tank 2. The connection tube 8 is inserted through the inlet section 14a of the collection container 12 and through the outlet section 14b made in the same container 12. The collection container 12 is then hooked to the fixing member 18 and firmly applied to the sleeve 21 inserted in the extraction opening 10 of the tank 2. The conveyor fitting 17 is connected both to the collection container 12 in correspondence with of the outflow section 16, which to the drain unit 9 of the wash unit 1 sink, through the manifold fitting 22.

When the head wash sink 1 is used for washing the hair, the mixing and / or interception device 5 is activated in the open condition, preferably at a suitable degree of mixing between the flow rate of hot liquid and cold liquid, for the supply from the water distribution network of the washing liquid at a suitable temperature.

The washing liquid, through the connection pipe 8, then reaches the delivery member 7, to wash the hair.

In the dispensing phase, the connection pipe 8 is movable, in particular in a sliding way, through the sleeve 21, to allow as much ease as possible for the washing operations carried out by the operator. Therefore, due to the continuous extraction and return motion of the connection pipe 8, a part of the washing liquid, generally water, possibly mixed with cleaning products added by the operator, can creep through the extraction opening 10.

In particular, liquid leaks can creep between the support sleeve 21 and the connection pipe 8 inserted therein.

These washing liquid losses are then efficiently collected by the collection container 12 of the collection group 11 and subsequently conveyed to the discharge group 9 provided on the washing tank 2, thus preventing liquid leaks from escaping from the washing tank.

According to a further possible embodiment of the invention, illustrated in Figures 5 to 8, the head wash sink 100 comprises a collection unit 110 in which the respective collection container 120 has a shape which is at least partially enlarged in the direction of fall of the liquid washing.

In practice, the collection container 120 comprises a collection base 121, a lateral wall 122 for connection to the base 121 forming a narrowing or neck 223, in correspondence with which the inlet section 140a is formed. The outlet section 140b for the connection tube 8 is formed in correspondence with an enlargement portion, with respect to the neck 123, of the container 120 itself, in correspondence with the side wall 122, instead of the bottom 121, as in the embodiment described in precedence.

Advantageously, the outlet section 140b can be made in the form, for example, of a simple opening made in the side wall 122, so as to be able to freely insert the connection pipe 8, ie without the interposition of particular sealing means. In fact, in this case, the liquid possibly dragged by the connection pipe 8 in the discontinuous and reciprocating motion of extraction, can fall, by virtue of the aforementioned enlargement portion downstream of the neck 123, in a safe way, on the bottom 121.

In practice, the collection container 120 can have, in this case, substantially the shape of a bottle. As in the embodiment illustrated above, the collection container 120 is preferably connected by means of the fixing member 18 to the support opening 10 of the washing tank 2. On the bottom 121 of the collection container 120 is present, as described previously and in a completely similar way, the outflow section 16, connectable to the respective conveyor fitting or connecting duct, not shown for simplicity. Between the outflow section 16 and the respective connection duct an interception member 124 can be advantageously interposed, able to control, for example manually, by opening or closing a control member 125, the outflow of the liquid collected in the collection container 120.

For the rest, the technical characteristics of the second embodiment described can be substantially similar, functionally and structurally, to those described above for the first embodiment.

The operation of this second embodiment is entirely similar to that described previously.

The present invention therefore achieves the purpose of providing a head wash sink that allows you to properly check and collect any leaks of liquid, generally water, coming from the washing tank through the extraction opening 10 of the dispensing unit 6.

This result is achieved mainly thanks to the inventive idea of equipping the head wash sink 1 with a collection unit 11, 110 suitable for the collection and possibly the controlled discharge of water leaks that may come from the unit through the extraction opening 10 6. The aforementioned collection unit can be easily applied to any wash unit sink, even if it already exists, simply by fastening the collection container 12, 120 to the washing tank 2 in a very easy and quick way.

In fact, the collection container 12, 120 can be assembled to the wash unit sink 1 both in the initial installation phase and subsequently, when the wash unit sink is already installed in the washing station.

Once the collection unit 11, 110 is connected, any loss of liquid carried by the extraction motion of the connection tube 8 of the delivery unit 6 is effectively collected in the collection container 12, 120, avoiding the risk of dangerous wetting of the floor and of the areas below the washing tank 2.

Advantageously, the discharge of the washing liquid leaks collected by the collection unit 11, 110 can be manually adjusted by means of interception means 124.

In the practical implementation of the invention, the materials used, as well as the shape and dimensions, can be any according to requirements.
