OF THE SINK TYPE

DESCRIPTION

The object of the present innovation is a new appliance for grouping and managing the various functions that can be performed with the use of sanitary ware such as a sink or washbasin, shower, bathtub or bidet, promoting easiness and safety in the installation, use, and maintenance thereof.

Main feature of the present innovation is to provide for the realization of a device comprising a hollow box with open side walls, with an open bottom surface that can be associated with a base plate, which is provided with holes for the passage of the supply tubes of faucets for hot and cold water, liquid detergent and any other liquid cleaning and personal care products, but also for the pouring of beverages or other liquids, as well as it can be provided with holes for the passage of cables or pneumatic connection ducts, for example for the command button of a waste shredder, while the top surface of the same box is provided with through holes for supporting and securing the above-mentioned faucets and buttons, allowing their connection to the respective supply tubes, directly or also by the interposition of an intermediate manifold, concentrating and making all the ducts of a washing and cleaning appliance easily accessible and inspectable, said base plate of said box being able to be associated with a perforated body, to be placed on the inner surface of the same sanitary appliance, where one end of its hole can catch any excess water thereof and the opposite end can discharge it into the drain duct of the same sanitary appliance.

It is well known that in every kitchen or room for the preparation of food, a sink is present near the hob, with a water-dispensing faucet for washing and cleaning vegetables and other foodstuffs to be prepared, as well as for storing dishes and cutlery to be washed after eating. Generally, a current kitchen sink is made of a thin sheet of pre-moulded stainless steel and has one or two compartments with their own drain valve, for the collection and disposal of waste water and its residues from washed food, after manual removal of the larger solid parts that could obstruct the drain, which parts are retained by a removable grid that is present on said drain valve.

More traditionally, the sinks themselves can be made of ceramic, marble, or other materials, and still have one or more washing compartments. At the top of each compartment there is normally a slit or overflow, which sets the maximum attainable level of water, collecting the excess water and feeding it into the drain duct below each drain valve.

In a more recent version, the traditional kitchen sink is also provided with a faucet for an independent dispensing of liquid detergent to be introduced into its cleaning compartment, after closing with a plug its drain valve, particularly for soaking dishes and cutlery to be washed or prepared to be then placed in an adjacent dishwasher, for example according to the teaching of patent applications No. US2012/0223159 and No. US2019/032315.

The functions of the traditional kitchen sink have recently been further enhanced by the application of a waste shredder, aligned with its drain duct, which collects the waste water and crushes the solid parts therein, allowing the discharge of all the washing residues into the white water network, without the need to have the formation and separate collection of the so-called wet waste, e.g. according to the teaching of the patent applications No. WO2019/241506 and US2006/278743.

In addition to these and similar measures to improve the functionality of a kitchen sink, there have also been other innovations that have supported and simplified the manufacture thereof, particularly by using materials other than ceramic, marble, or stainless steel, for example by using Corian, Tecnoril or Cristalplant, which have also enabled designs that are certainly more attractive and better suited to the furnishing style of a modem kitchen, as well as for the realization of washbasins and other sanitary appliances, for example in the bathroom. On one hand, the use of these new materials in the construction of these appliances offers great advantages in terms of resistance and aesthetics, but on the other hand it generally results in the disappearance of the overflow slit, due to the thickness with which said new sinks are made, which thickness makes the formation of a gap compartment and the application of an overflow connection fitting difficult, thereby the new appliances are generally unable to guarantee the maximum water collection level in their compartment. In order to overcome this drawback, these new sinks can be used without the presence of the closing plug of the drain valve, except for the insertion of collection grids, or by the use of a "click -clack" valve, by which a partial filling of the compartment during a washing step is always allowed.

The presence of all these additional elements and expedients, compared to the traditional shape of a sink or other washing appliance, for example in a kitchen, restaurant, or laboratory, on one hand has improved and enriched the functionality of use thereof, but on the other hand has made its installation and the connection of its ducts more complicated and laborious, as well as making any future maintenance or modification operations more difficult, particularly due to the difficulty of placing and securing the various pipes and connecting its ducts and management faucets, frequently requiring the resurfacing of the wall or floor tile coating of the room where the same appliance is located.

These felt drawbacks have been solved by this innovation, by means of which it is possible to simplify the installation of a sink or other sanitary cleaning appliance that is complete with all or part of these current functional elements, in accordance with its intended use, and which can support and simplify any future updating and maintenance operations.

In fact, the main task of the present innovation is to be able to optimise the management of the various functions provided for a modem sanitary washing appliance, grouping them together in a single appliance that is easily applicable and accessible, also for any possible form of maintenance or future modification and updating of its terminal connections.

As part of this task, another important object of the present innovation is to have a single inspection compartment for the connection of the hot water and cold water pipes and the duct for liquid detergent or other soap or hygienic and cleaning fluid.

Another important object of the present innovation is to allow the presence of an overflow duct even in new sinks or sanitary washing appliances that currently do not have a slit and an overflow collecting chamber. A further object of the present innovation is to create a space available for attaching and connecting the button for operating or storing the shredder or heatsink of solid food waste in the waste water of the sink.

These and other objects are in fact perfectly achieved by the present innovation, as exemplified herein below and in accordance with the appended claims, by which innovation the realization of a hollow box with open side walls, with a base plate that is provided with holes for the passage of the supply tubes of faucets for hot and cold water, liquid detergent and any other cleaning and personal care liquid products is provided for, as well as it can be provided with holes for the passage of a pneumatic duct for the command button and storage of a waste shredder, while the top surface of the same box is provided with through holes for supporting and securing the above-mentioned faucets and buttons, allowing their connection to the respective supply tubes and cables, said base plate of said box being able to be associated with a support or perforated body, to be placed on the inner surface of the same sanitary appliance, where one end of its hole can catch any excess water thereof and the opposite end can discharge it into the drain duct of the same sanitary appliance.

A more complete illustration of the present innovation and the verification of its compliance with the specified objects is better illustrated by the following description of a constructive form of the device under consideration, conforming to a purely indicative and non-limiting solution thereof, illustrated herein below also with the aid of 13 schematic figures reproduced in 8 attached tables, and of which:

In all figures the same details are identified, or understood to be identified, by the same reference number.

With reference to Figs. 1 to 7, an inspection appliance (1) of the functions of sanitary appliances is applied on a kitchen sink (A), where the various management functions such as the supply of hot and cold water, the supply of liquid detergent, the possibility of an overflow drain and the possibility of operating or storing command of the waste shredder under the sink, can be cumulatively present and activated. However, the same finding can also be applied, completely or partially, in other sanitary cleaning appliances, adapting it to the respective requirements and functions, as exemplified in the constructional variation solutions in Figs. 8 - 9, Figs. 10 - 11, and Figs. 12 - 13.

In accordance with the constructional solution exemplified in Figs. 1 to 7, an appliance for the management (1) of the functions of a sink (A) is substantially composed of a base body or support (10), an intermediate body or spacer (20), and an upper open box (40) with a base plate (30), on which box (40) the hot and cold water supply faucet is fixed with its mixer (B), as well as the faucet for dispensing liquid detergent (C) and a button (D) for operating an underlying shredder, while the same base body (10) also allows the possibility of adjusting the overflow of the basin of the same sink (A).

More in detail, with reference to Figs. 4 - 5 and 6 - 7, the base body (10) consists in a parallelepiped having a front face (11) that is contacted with an inner surface of the sink (A), through the interposition of a suitable gasket housed in its peripheral groove (11/a), said surface (11) being secured to one side of the sink (A) by means of suitable screws, which are screwed to its blind and threaded holes (10/a).

Of course, the securing point of the lower body (10) on the inside wall of the sink (A) corresponds to the intended point of arrival of the mains water and liquid soap supply pipes, preferably flexible, as well as the underlying drain duct of waste waters.

The front wall (11) of the block (10) is orthogonal to the upper smooth surface (13) and to a lower smooth surface (12), which are defined by the opposite vertical wall (19).

Orthogonal to the surface (11), there are an axially blind oblong hole (14), a cylindrical and axially blind hole (15), and a partially blind cylindrical hole (16).

The oblong blind hole (14) of the block (10) orthogonally communicates with a corresponding oblong blind hole (17) that is open on its upper surface (13), while the cylindrical blind hole (15) is open and communicates with the corresponding cylindrical hole (18) of the same flat surface (13). Also with reference to Figs. 6 and 7, the partially blind hole (16) of block (10) has a perforated end (16/a) which is tangent to it and has a minimum diameter, therefore arranged parallel to its upper side, and communicates with an orthogonal hole (16b) that is open on the lower surface (12) of the same block (10). The same partially blind hole (16) has a threaded initial part (16c), in order to be able to connect with a duct communicating with the drain tube of the sink (A).

The side (11) of said lower block (10) is completed by the presence of horizontal blind, threaded holes (10/a) adapted for screwing screws, not shown, to secure it to the wall of the sink (A), while a series of blind, threaded holes (10/b) are adapted for the passage of vertical screws for joining the same block (10) with the intermediate block (20) above and its upper plate (30), by means of other screws, not shown.

In conclusion, the presence of the draining hole (16/b) allows the excess water in the sink (A) to be discharged from the duct applied to the threaded connection ( 16/c) and to be collected, to be connected to the drain duct at the bottom of each sink basin, thus constituting an overflow system to be applied in modem sinks that currently do not have one, in compliance with one of the specified objects, while the hole (16/a) performs a venting function.

As already mentioned, the central part of the appliance (1) consists of a body or spacer (20) that is superimposed and secured to the upper surface (13) of the base block (10).

In more detail, as shown in Figs. 4 and 5, the spacer (20) consists of a parallelepiped having smooth side walls, while a lower surface (21) and an upper surface (22) have a pair of oblong through holes (27 - 28), or a single oblong through hole (27 - 28), in any case adapted to be placed above the holes (17 - 18) of the base block (10), to clear the passage of the mains water supply pipes, the detergent, and any other devices installed under the sink (A).

The lower (21) and upper (22) surfaces of the spacer (20) are provided with respective grooves (21/a) and (22/a) for housing a sealing gasket to be interposed between the spacer (20) itself and the upper surface (13) of the support (10) and the lower surface (32) of an upper plate (30), respectively. Finally, the same faces (21 - 22) of the intermediate block (20) communicate with each other by means of a series of through holes (20b), within which the same number of closing screws, not shown, are made to pass for their connection to the lower block (10) and to the upper plate (30).

A base plate (30) of the upper box (40) is provided with an upper (31) and a lower (32) surfaces, which are smooth and provided with a pair of oblong through holes (37 - 38) that are perfectly superimposed on the holes (27 - 28) of the spacer (20), or with a single oblong opening (27 - 28). In addition, the same plate (30) is provided with through holes (30b) that can be superimposed on the through holes (20b) of the block (20), for the insertion of as many screws, not shown, the threaded shank of which is inserted in said respective holes (30b) and (20b) that are then screwed to the corresponding threaded seats (10b) present on the base block (10), while their head closes and joins the plate (30) with the spacer (20) and the base block (10), forming a single sealed connection element of the water and detergent ducts, towards their mixing and dispensing faucets (B - C) and connection with the button (D).

The characteristic of the plate (30) is that it preferably corresponds to the width of the underlying blocks (20) and (10), having however a greater length, with respect to the position of its holes (37 - 38), in order to be able to protrude from said underlying blocks (20 - 10), and create the base of an inspection compartment (41) that can be obtained via the application of the head box (40), as specified herein below.

The inspection box (40) basically consists of a parallelepiped with a central cavity (41) and four sides (42 - 43 - 44 - 45) that are provided with at least one of the respective windows (42/a - 43/a - 44/a and 45/a), as well as a smooth upper surface (46) and an open bottom (41/a).

The aforementioned plate (30) is housed in the open bottom (41/a) of the box (40), where it is secured by four screws, not shown, passing through its diagonal holes (30/a) to screw into the threaded blind holes (40/a) of the same box (40), as shown in Fig. 5. Alternatively, the same plate (30) can be permanently secured or welded onto the same open bottom (41/a) of the box (40).

Also with reference to Figs. 1 - 2 and 3, the upper surface (46) of said box (40) is by way of example provided with three cylindrical through holes (47 - 48 and 49). The hole (47) is by way of example intended to house and secure the tap and mixing assembly (B) for dispensing hot and cold water, while the hole (48) houses and supports the liquid detergent dispensing assembly (C), and the hole (49) houses and supports a button (D) that activates or stores the activation of a waste shredder. The tank for said liquid detergent and the location of said waste shredder can normally be arranged in a cabinet located under the sink (A).

Alternatively, the ceiling (46) can be made separately with its own holes (47 - 48 and 49) and attached to the upper edge of the walls (42 - 43 - 44 and 45) securing it by means of screws or by welding, in the same way as for securing the plate (30) to the bottom (41/a) of the same box (40).

In accordance with the realization solution illustrated in Figs, from 1 to 7, a water branch coming from the external grid is heated and led out parallel to the cold water in two separate flexible ducts that pass through the holes (14 - 17) of the block (10), then passing through the holes (27) of the spacer (20) they come to slightly protrude from the hole (37) of the plate (30), where, directly or with an intermediate connection manifold, they are connected to the faucet (B) and the incorporated mixer thereof.

Similarly, the liquid detergent of a container is pushed by a pump thereof into a flexible duct which, passing through the hole (15 - 18) of the block (10) and the hole (28) of the spacer (20), slightly protrudes from the hole (38) of the plate (30), where, directly or with an intermediate manifold, it is connected to the dispenser (C).

A duct, preferably pneumatic, not shown, connects the motor of a waste shredder located under the sink (A), passing for example through the holes (14 - 17) or (15 - 18) of the block (10), as well as through the hole (27) or (28) of the spacer (20) it can exit the hole (37) or (38) of the plate (30) and be connected directly or with a connecting manifold, into the compartment (41) of the box (40), with the button (D).

The housing and fastening of the faucet and mixing assembly (B), as well as the housing and fastening of the assembly (C) and the housing and fastening of the button (D) are fitted in the respective holes (47 - 48 and 49) of the box (40) according to a known technique that it was not considered necessary to illustrate. Of course, the same holes (47 - 48 - 49) or others that may be required for a different use of the sink illustrated in Fig. 1 may be present and used for dispensing faucets for other liquids or drinks, as well as other buttons to control particular functions of the sink and the device (1) described and illustrated so far.

Advantageously, within the compartment (41) of the inspection box (40), between the arrival point of the hot and cold water pipes, indicatively arranged at the plate (30) level, and their connection with the corresponding access pipes to the faucet (B), an union manifold can be interposed and applied, which allows the supply of cold and hot water to the faucet (B), while the mixing thereof is adjustable according to a known technique.

In accordance with the constructive solution so far described and illustrated by way of example with the aid of Figs. 1 to 7, the plate (30), already joined to the spacer (20) and the base block (10) and the inspection box (40) on the whole forms the device (1) that makes the connection and control of the various inlet functions of the sink (A) possible, including the above-mentioned overflow function, in accordance with some of the specified objects.

With particular reference to Figs. 4 and 5, the inspection box (40) is advantageously provided with small doors (50), which are intended to be housed with good precision in the side openings (42/a - 43/a - 44/a - 45/a) of its side walls (42 - 43 - 44 and 45). The same small doors (50) are provided with spring balls (51) that promote the housing stability in said openings and allow them to be easily withdrawn, should it be necessary to access the compartment (41).

Of course, it is possible to provide for the creation of a box (40) that provides for the opening only of a part of the windows (42/a - 43/a - 44/a and 45/a), as well as it is possible to provide for the creation of small doors (50) or walls (42 - 43 - 44 or 45) that are provided with holes (47 and/or 48 and/or 49) while the ceiling (46) is completely closed and without holes or only provided with a part of said holes for a supply also on the lateral part of the same functions described above.

Compared to the current state of the art, where each individual function for supplying water, detergent, for controlling the shredder and activating the overflow is located in different points of the sink, with the present finding, the same functions are grouped and concentrated in a single appliance that allows an easy inspection, both during the initial application and during an intervention to replace, for example, an end fitting or a supply cable, without having to disassemble the sink or part of the system thereof, in accordance with some other of the specified objects.

The realization of the appliance (1) so far described can of course be achieved also in other constructive forms. As an example, it is usual to indicate the possibility that the spacer (20) and the plate (30) are made as a single piece with the block (10), with a single oblong through hole (27 - 37 - 28 - 38). The same spacer (20) can be made as a single piece with the base (10) and the plate (30), eliminating the presence of the various through holes (10b - 20b and 30b) and the respective joining screws, while having the various holes (14 - 15 - 16 - 17 - 18 - 27 - 28 and 37 - 38) as specified above. Again, said spacer block (20) can be made in a single piece with only the base (10) to be then associated with the plate (30) by means of appropriate screws. Finally, particularly in the case that the overflow block ( 10) is not provided for, and the presence of a spacer (20) is not required, it is possible to provide for the application of the plate (30) and its inspection box (40), either by directly securing it to a plane or floor (P), or by securing it directly to a masonry (M), from where the supply pipes of the faucet (B), the dispenser (C), and the possible button (D) arrive.

Of course, the parallelepiped shape with which the bodies (10 and 20) and the box itself (40) have been illustrated can be varied into other more stylised and ergonomic rounded shapes, as can the in-line or side-by-side arrangement of their holes (14 - 15 - 16 - etc.), always in accordance with their functions described above. Similarly, the substantially cubic shape of the inspection box (40) can be replaced, for example, by an elongated cylindrical or polygonal shape, in which the various faucets and buttons are arranged on corresponding cover surfaces (46).

Again, according to what has been so far described and illustrated by way of example, it is understood that, after securing the appliance (1) onto a side of the sink (A), after securing the faucet (B) and the passage for the water through the hole (47), then after securing the liquid soap faucet (C) in the seat (48) and after securing the button (D) into the hole (49) of the upper plane (46) of the box (40), with the presence of the windows (42/a - 43/a - 44/a and 45/a), it is easy to enter its compartment (41) to connect them to the ends of the pipes protruding from the holes (37 - 38) of the base or plate (30), concentrating within the inspection box (40) all the functions predetermined for the sink (A), while the draining hole (16b) of the block (10) allows to drain the overflow of the same sink (A), as well as promoting the maintenance thereof and any possible update or modification, in compliance with some of the specified objects.

By what has been described and illustrated so far, it is understood that, in the case of traditional sinks that are already equipped with an overflow slit, it may not be necessary to apply the base block (10) and its draining (16b) of excess water, as it is sufficient to use the device (1) for its sole function as a collector and dispenser of hot and cold water, as well as of the liquid soap, other hygienic liquid, and the availability of the control or storage button for the waste shredder.

As already mentioned, the constructive form of the inspection appliance or device (1) under consideration may also vary according to specific needs or situations of the rooms or sanitary appliances to be managed.

Figs. 8 and 9 illustrate a first constructive variation of the inspection appliance (1), in a simplified solution (1’) compared to the solution illustrated in Figs. 1 to 7, and particularly applying to appliances that dispense hot and cold water, as well as liquid soap, or shampoo, or other cleaning and personal care liquids, for example for showers or bathtubs, where their supply ducts come from under the worktop (P) of the sink (A) or from a resting floor (P) of a similar sanitary appliance (A) to be connected to said pipes. In this case, as it is not necessary to have a block (10) with an overflow duct (16b) or a spacer (20) to adjust its height, the appliance (1’) provides for the presence of a plate (30’) with its own central metal tube (37’), which is for example welded or screwed and to be secured to the top (P) for example by a ferrule (G), said metal tube (37’) having the possibility of making the hot and cold water ducts pass through and the other ducts to be connected respectively with its faucets (B) and (C), as well as a button (D) and the control duct of the possible shredder. From the same Figs. 8 and 9, it can be seen that the edge of said plate (30’) is adapted to house the lower edge (41/a ¹ ) of an inspection box (40’) so as to ensure a precise and solid but snap-openjoining thereof. The same plate (30’) can alternatively be welded or otherwise firmly attached to the box (40’).

Futhermore, with reference to the same Figs. 8 and 9, the inspection box (40’) is made in an elongated cylindrical shape, its upper surface (46’) being provided with a hole (47’) for housing and securing a hot and cold water faucet assembly, a hole (48’) for housing and securing a liquid soap dispensing faucet, and a hole (49’) for housing and securing a command and storage button of a possible shredder, arranged together with the liquid soap container under the worktop of a sink. If the command button for an improbable waste shredder is missing, the inspection box (40’) may be shorter and without the hole (49’), just as a similar hole (49’) may be absent or used, for example, for an additional faucet for dispensing shampoo or other personal cleaning liquid.

The same inspection box (40’) is also equipped with two side windows (42/a’ - 44/a’) obtained along the flat walls (42’ - 44’) that make the access to the internal compartment (41 ’) possible, in order to operate on the ends of the pipes and supply cables passing through the hole (37’) of the plate (30’) and the connections of the respective faucets and buttons (B - C and D). It is still possible to equip the plate (30’) with a plurality of holes and ducts (37’ - 38’), in which the pipes for water and liquid soap or other material coming from below can be passed separately, each duct (37’ - 38’) possibly being able to be secured to the worktop (P) by means of respective ferrules (G).

Again, with this constructive variation, the inspection box (40’) perfectly fulfils the object of concentrating the functions of the sink (A) or other sanitary cleaning appliance in a single appliance (1’), making the inspection easy, both during its initial application step and in a subsequent intervention step, even due to the possible addition of a new function, without having to disassemble the sink or a part of the system, which complies with some of the specified objects. As already mentioned, the junction box (40’) can be applied, for example, for the management of a shower or other sanitary appliance for cleaning and personal hygiene. In this case, in addition to the faucet with mixer (B) for dispensing water and the liquid soap dispenser (C), there may be one or more dispensers, e.g. for shampoo or conditioner or other fragrances for personal hygiene and well-being, each faucet being supplied by its own duct passing through the appliance ( 1 ’) and converging in the junction box (40’).

With reference to Figs. 10 and 11 of table 7, a further simplified constructional variation (1”) of the appliance (1) and its inspection box (40) is proposed, compared to the solution of Figs. 1 to 7 is proposed. In particular, the device or appliance (1 ”) is adapted to be applied to the wall of a masonry (M), in case the pipes for water, soap, or other liquid substance come from the same masonry (M) or from another adjacent wall, passing through a hole (F), for example being walled in from the floor of a kitchen or room.

Also in this constructive solution, a box (40”) shaped as a radially elongated cylinder is proposed, with an internal cavity (41 ”) and a pair of windows or lateral openings (42/a” - 44/a’ ’) obtained on its flat walls (42” - 44”), from which openings (42/a’ ’ - 44/a’ ’) it is possible to intervene to link and connect the pipes for water, liquid soap, and/or other liquid personal cleaning substances coming from the duct (37”) of the plate (30”) and destined to the dispensers (B and C) of the sink or other personal cleaning appliance.

From the same Figs. 10 and 11, it is understood that said plate (30”) is arranged abutting against the surface of a part or wall (M) and is provided with one or more holes (37” - 38”) to which the ends of flexible or rigid pipes are associated, which pipes pass through the holes (F) of the same masonry (M), for the passage of the hot and cold water pipes of a sink, as well as the duct for the liquid detergent or other cleaning liquid, perfumes or a drink to be dispensed, as well as the possible presence of a duct for the connection to a waste shredder of a sink or other sanitary cleaning appliance.

According to the construction solution of Figs. 10 and 11, said plate (30”) is provided with at least one hole (37”- 38”), through which the aforementioned pipes and cables pass, and it is provided with through holes (30/b”), which allows the passage of hanger screws to the wall (M) with which it is thus firmly secured.

Again according to this representation, the inspection box (40”) is shaped in a radially elongated cylindrical form, having a cavity (41 ”) and a lower edge (41/a”) that snaps over the edge of the plate (30”) to allow a sufficient removability. Alternatively, the edges of said plate (30”) can be welded or otherwise secured to the lower edge (41/a”) of the box (40”). The flat side surfaces (42” - 44”) of the same box (40”) are provided with corresponding openings (42/a” - 44/a”) that allow a good accessibility for the application of the connections between the ends of the liquid detergent and water ducts and the respective fittings of their dispensing faucets (B - C), as well as the possibility of a connection between the entering cable and the button duct (D), according to what has already been illustrated above.

The flat external surface (46”) of the box (40”) is provided, by way of example, with a through hole (47”) for housing and securing a faucet (B) for the supply of hot and cold water, while the through hole (48”) is adapted to house and secure the liquid detergent dispensing faucet (C) and the through hole (49”) houses and secures the button (D) for controlling and storing the possible waste shredder or other cleaning liquid dispenser. This hole (49”) may not be present or replicated for the number of dispensers that can be achieved with said appliance (1”).

With reference to Figs. 12 and 13 of table 8, as already mentioned, a further constructional variation (1”’) of the appliance (1) of Fig. 1 is proposed, for the application thereof on the worktop (P) of a kitchen or a sink (A), similar to the solution of Figs. 8 and 9 but with the presence of a spacer (20”’) that allows the faucets (B and C) with the possible button (D) to be brought to a predetermined height.

In more detail, the spacer (20”’) of the appliance (1’”) is shaped in an inverted, hollow, frustoconical form, and it is equipped with a flange (29’”) which connects it to a manifold (27’”) through which the above-mentioned pipes and ducts pass. The flange (29’”) allows the spacer to rest on the plane (P) and cooperates with a ferrule (G) that closes along the threaded manifold (27’”) for a stable attachment thereof. The upper edge of the spacer (20”’) is adapted to house a plate (30’”), which is either secured thereto by means of screws passing through holes (30/b”’) or welded to it, while the outer edge of the same plate (30’”) is provided with holes (30/a’”) for the passage of screws for securing the lower edge (41/a) of the box (40).

Said box (40) of Figs. 12 and 13 is substantially identical to the box (40) of the appliance ( 1) already illustrated in Figs. 1 to 5, and it can therefore be joined to the plate (30” ’) or welded to its lower edge (41/a’”). The plate itself (30’”) has a single central through hole (37’”), through which the tubes and cables from the cavity of the spacer (20’ ’ ’) and its manifold (27” ’) pass.

Similarly, the possibility to use the same plate (30) as the solution in Figs. 4 and 5 for the base of the box (40) of the device (1’”) in Figs. 12 - 13 provides for the alternated presence of the through holes (37 - 38) in place of the single through hole (37’” - 27’”), as wells as its flange (29) can be provided with through holes to secure it to a floor (P).

The inspection device, in the constructive solution (1 ’”) of Figs. 12 and 13 can still be associated with a base block (10) of Figs. 6 and 7, where, to the functions of supplying the various pipes and ducts of the dispensers (B and C) the possibility is added to apply an overflow, which can be achieved with its holes (16 - 16/b and 16/a), obviously adapting its connection modes, as already specified.

In all the solutions exemplified above, it can be provided for that the holes (49 - 49’ - 49”) for housing buttons (D) for controlling a waste shredder can be eliminated, as well as the possibility of applying buttons (D) for other types of electrical remote control. The same outer flat surfaces (46 - 46’ - 46”) of the respective types of inspection boxes (40 - 40’ - 40”), particularly for shower or bathtub applications, can still be provided with a plurality of holes for dispensing other liquid substances such as shampoo, conditioners or other cleaning and wellness products, as well as for dispensing beverages or other liquid substances.

With reference to Fig. 1, the appliance (1) under examination, complete with its base block (10) for the overflow function of the sink (A), is randomly arranged along the rear side of the sink (A), while, in fact, the same device (1) can be arranged along any of its sides where the pipes and cables converge. By equipping the same base (10) with a suitable right-angle side, the same appliance (1) can be secured to a comer of the sink (A), fixing it to two converging sides thereof, after an angular arrangement of the hot and cold water supply pipes, as well as the one for the detergent and any other connection ducts. These and other similar modifications or adaptations of the inspection appliance and its system of use shall in any case be deemed to be part of the originality of the finding that is intended to be protected.
