DESCRIPTION OF INVENTIONTitle: Multi Function FaucetTechnical Field: This invention relates to sink faucets.Background ArtKitchen sink faucets are of the typical and preferred mono-block type. They have arrangements for regulating the water flow and mixing the hot and cold supply. Generally the spout is so designed to swivel about on an axis to provide some degree of adjustment so the nozzle can be aimed. Attachments such as soap dispensers and sprayers are also included as sink and faucet peripherals.
To satisfy local authority water by-laws the faucet spout has to meet the requirements of having two separate channels or conduits for the flow of the hot and cold supply without mixing until the nozzle stage.
Prior art indicates that in the case of U. S. Patent no. 5906319, A water soap sprayer for attachment to a kitchen faucet is utilised to apply a soap liquid via a brush head this arrangement has the advantage that the unit has a flexible hose attached to the unit thus a good degree of adaptability is ensued in its operation.
U. K. Patent no 2277443 illustrates A sink pull out spout, which is attached to a flexible hose and has the obvious advantage of being able to direct the flow so is effective in the easy fill of mop buckets and the like.
D. E. Patent no 3835738 depicts a hot and cold mixer tap with integrated soap dispenser which the advantage of dispensing soap within the vicinity of the of the faucet nozzle, other prior art suggests various embodiments on the same theme.
However they suffer from the drawback that the singularity of either function has not resulted in the dual purpose of operation. An integrated system would there for be beneficial that would culminate in both soap dispensing and nozzle extension in a compact design, lowering manufactured costs and yet in keeping with an aesthetic appeal.It is there for the intention of the present invention to address such while fulfilling water authority by laws. SUMMARY OF THE INVENTION Tns present invention is directed to facilitate the cleaning of soiled kitchen utensils and its practicable adaptation of filling mop buckets and the like. The device is incorporated within the spout of the faucet and contains a flexible multicore conduit which communicates the hot and cold water supply source and a service line for washing liquid which is dispensed via a receptacle attached to the spout and is expelled through the engagement of a pump located on the detachable nozzle.
It is the principal objective of the present invention to provide a means to clean more effectively soiled kitchen utensils by means of detachable nozzleIt is also another object of the invention to dispense washing liquid directly through the faucet nozzle.
Another object of the invention is that the attachment of a pot scourer, brush or sponge can be affixed to the nozzle. It will be observed that due to the flexible nature of the multicore conduit that the nozzle can be aimed and easily be orientated to various uneven surfaces, and that placement of the nozzle can be directed over the side of mop buckets and the like without the hindrance that a fixed spout would encompass. Difficulties are often encounted in this task because conventional faucet swivel spouts have transverse movement only, so when a bucket is being filled a proportionate amount of water has to be spilled in order to avoid the entrapment of the spout when lifting the bucket out of the sink.
Applying and dispensing washing up liquid is often by squeezing a bottle of such into the sink basin. This task is carried out according to the invention by a simpler method and has the advantage that a pump and push button is devised into the nozzle head.
Alternatively sink basins that are appropriately used for public conveniences could have hand soap deposited in the soap receptacle serving the comfort for hand washing.
The flexible multicore conduit is manufactured from polymers. Such polymers would have to with stand heat and continual flexing without degradation to give a good service life. Polymers such as PVC (Polyvinyl chloride) or Polyurethane would deem suitable plastics that can operate within the temperature range of the domestic hot water supply yet give the flexible nature that would be required. Moulding such an elongated coil could be achieved by injection moulding.
Various embodiments of the invention can be envisioned without detracting from the spirit of its novelty with someone practised in the art.
DescriptionA preferred sink faucet accommodating a liquid soap dispenser and detachable nozzle is thus explained, with reference made to the accompanied drawings.
Figure (1) illustrates a cross sectional view depicting the retracted multicore conduit.
Figure (2) illustrates a cross sectional view of the nozzle extended.
Figure (3) illustrates a perspective view. Water controlled valve supplying the hot and cold source is terminated within the rear end of the spout (1). A multicore conduit (2) that is flexible in nature and communicating the water supply and liquid soap is so connected at unions (3) Access to said unions is by an inspection end feed blanking plug (4) Liquid soap reservoir situated atop of spout (5) and discharge line fed into said multicore conduit, which is configured into an elongated coil and retracted within said spout. Termination of the multicore is affixed to respective union's integral to the nozzle assembly (6). A pump mechanism (7) is activated on the said nozzle for the dispensing of liquid soap into common nozzle outlet (8).
Disengagement of said nozzle from spout via flanged collar (9).
Nozzle extension is achieved by elongation of multicore and retracted when not in use.
