[0001] This invention concerns a kitchen mixer tap for use in sinks, where it gives a separate
supply of hot/cold water for domestic use and purified water for food purposes, for
example.
[0002] The need for a tap capable of supplying different kinds of water separately originates
with the problems of environmental pollution and, therefore, from the need to prevent
possible harm caused by the use of polluted water, or at least non-purified water,
for cooking needs.
[0003] There are already kitchen taps on the market which adopt the concept of water separation
but, by the very nature of their conformation, they cannot guarantee completely that
the water for cooking needs does not come into contact with and become polluted by
the water for sanitary purposes, especially because the supply points of the two water
types are concentric or adjacent. In effect, the taps currently on the market generally
use one outflow mouth for the two different types of water, leaving the doubt in the
user's mind about whether they are really and effectively separate, since he has no
visual confirmation of their separation.
[0004] The aim of this invention is to supply a kitchen mixer tap in which the hot/cold
water for sanitary use and the purified water for cooking purposes are physically
and tangibly kept separate along the whole of their passage, what is more, this being
observable by the presence of a mouth for each type of water.
[0005] Said aim is achieved by means of a tap with a single body that incorporates the dual
control function of mixing and supplying the hot/cold water and supplying the purified
water, and consisting of two independent and rotating mouths on said body, one for
the outflow of the hot/cold or mixed water, the other for the outflow of the purified
water.
[0006] However, further details of the invention will become clear from the following description
which is made with reference to the drawings enclosed, which are indicative but not
binding, and in which:
Fig. 1 shows a cross-section of the mixer tap;
Fig. 2 shows an external view of the tap with the two mouths aligned; and
Fig. 3 shows the tap with one of the mouths rotated with respect to the other.
[0007] The tap consists of a body 11 which is mounted in the usual way on a sink 12, and
which contains a mixer valve 13 on one side for the hot and cold water, commanded
by a respective lever 14, and on the other side, a bolt-type valve 15 commanded by
its own handle 16. The hot and cold water to be mixed reaches the mixer valve 13 through
separate input pipes 17, 18. The purified water arrives, for example, from a filtering
device for the mains water and flows through a pipe 19 which is directly connected
to the bolt-type valve 15.
[0008] A support 20 is applied to the top of the tap, to which a rotating fitting 21 is
added with a leak-proof fastening, held by a screw 22 and holding, in turn, the two
separate and independent mouths 23 and 24 for the mixed hot/cold water and the purified
water, respectively. One mouth is connected, via a passage 23' made in the rotating
fitting 21, to the outflow of the mixer valve 13, and finishes in a jet controller
25; the other mouth is connected, via another passage 24' made in the rotating fitting
21, to the bolt-type valve 15 and terminates in a supply nozzle 26.
[0009] Therefore, the two types of water to be supplied pass through independent mouths.
The purified water follows a completely different path from that of the hot/cold water,
having no point of contact or interference with the latter, and flowing from its own
nozzle.
[0010] It should be noted that the fitting 21 fastened to the support 20 allows the two
mouths 23, 24 to rotate contemporarily through 360°. Furthermore, the mouth 24 for
the outflow of the purified water is free to rotate through about 90° with respect
to the mouth 23 of the mixed water (Fig. 3).
[0011] Finally, it should be noted that, in place of the purified water, other kinds of
water may be supplied through the mouth 24, such as sparkling water or chilled water,
which arrive from their appropriate supply sources.
1. Kitchen mixer tap for supplying hot/cold mixed water for domestic use and purified
water for cooking purposes, consisting of a single body (11), a mixer valve (13) connected
to supply pipes (17, 18) for the hot/cold water and a bolt-type valve (15) connected
to a source of purified water, characterised by two supply mouths (23, 24), which are separate and independent and which extend from
said body, a first mouth (23) for the supply of the hot/cold water arriving from the
outflow of the mixer valve, a second mouth (24) for the supply of purified water arriving
from the outflow of the bolt-type valve.
2. Tap according to claim 1, in which the two mouths (23, 24) are fixed to a fitting
(21), applied in rotating form to said body by means of a fixed support (20), and
the first mouth (23) communicates with the outflow of the mixer valve (13) via a first
passage (23') made in said fitting (21) and in said support (20), and the other mouth
(24) with the outflow of the bolt-type valve (15) by means of a passage (24') which
is also made in the fitting and the support.
3. Tap according to claim 1, in which the mouths (23, 24) rotate contemporarily through
360° with respect to the vertical axis of the tap.
4. Tap according to claim 1, in which one mouth rotates through 90° with respect to the
other.
5. Tap according to claim 1, in which the mouths (23, 24) rotate contemporarily through
360° with respect to the vertical axis of the tap and one mouth rotates through 90°
with respect to the other.
