[0001] The present invention relates to a sink for kitchens, bathrooms and the like, whose
cost of manufacture is substantially lower than that of the known sinks.
BACKGROUND OF THE INVENTION
[0002] Widely known in the art are sinks for kitchens, bathrooms and the like, which are
made up of a body and have fitted into their drainage outlet a valve provided with
a plurality of orifices to permit water to pass through the drainage outlet.
[0003] In the known sinks said valve is a part independent of the body of the sink, the
valve being fitted during the sink manufacturing process.
[0004] Moreover, in the known sinks said valve includes a closure fitment which permits
the passage of water through the drainage outlet to be closed off. This closure fitment
can be a plug which is independent of the valve or a movable fitment incorporated
into the valve, which must be fitted during the sink manufacturing process.
[0005] The valves are usually fixed to the drainage outlet by perimetric welding, while
to the underside they are attached by means of a clamp to the pipe which leads to
the U-bend, thereby achieving a watertight seal between the valve outlet and the pipe.
The closure fitment is usually basket-shaped and is attached to the valve by means
of a bolt, allowing the closure fitment to move with respect to the valve.
[0006] Clearly, this construction is complex and expensive, involving a high percentage
of waste material due to the sections which must be cut out and hollowed in the manufacturing
of said components.
[0007] The sink of the invention for kitchens, bathrooms and the like, which sink calls
for a much simpler manufacturing process and substantially lower manufacturing cost,
has been designed in order to solve the aforesaid disadvantages, while at the same
time fulfilling a function identical to that of the currently known sinks.
DESCRIPTION OF THE INVENTION
[0008] The sink of the invention for kitchens and bathrooms is characterized in that the
valve is formed of a single piece with the rest of the sink body, said valve being
a cavity provided with a plurality of orifices made in the bottom of the body.
[0009] This characteristic provides a sink whose manufacturing process is much simpler,
with considerable saving of materials and labour.
[0010] The sink of the invention also provides the following advantages:
a) Reduction of the following processes in die-pressing of the valve:
- cutting of strips;
- cutting of discs;
- die-pressing the valve body;
- cutting away of excess material from the die-pressing process;
b) Reduction of the cost of polishing, since it is included in the cost of polishing
the sink;
c) Easier installation;
d) Lower consumption of materials:
- the greater cost, pertaining to the main valve body, is eliminated, for that body
now forms a single piece with the sink body;
- reduced size of the lower base which is attached to the central part of the bottom
of the sink, which is the site of the drainage outlet, since the diameter of the drainage
outlet is some 50% smaller than the orifice which forms the drainage outlet in the
known sinks;
- smaller measurements of the leaktightness gasket required to seal the bottom part;
e) Prevents the possibility of water leaks around the valve periphery due to faulty
installation or damage to the leaktightness gasket which seals the valve against the
sink;
f) Prevents the accumulation of dirt on the edge of the valve.
[0011] The valve can also include a movable closure fitment which in a first position allows
water to pass through the orifices towards the drainage pipe and in a second position
closes off the passage of water.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] For a better understanding of the matters described in this specification some drawings
are attached which, solely by way of example, show a practical case of embodiment
of the sink of the invention.
Figure 1 is an elevation view in cross-section of the sink of the invention for kitchens,
bathrooms and the like; and
Figure 2 is a plan view of the sink of the invention for kitchens, bathrooms and the
like.
DESCRIPTION OF A PREFERRED EMBODIMENT
[0013] As can be appreciated in Figure 1, the sink of the invention is made up of a body
1 whose lower part has a cavity 2 which functions as a valve. This valve 2 forms a
single piece with the rest of the sink body 1.
[0014] As can be appreciated in Figure 2, the valve 2 is provided with a plurality of orifices
3 which permit the outlet of water towards the pipes (not shown).
[0015] The sink of the invention also includes a closure fitment 4 which permits selective
opening or closure of the passage of water through the orifices 3 of the valve 2.
Figure 1 shows an embodiment of said closure fitment, which is made up of a basket-shaped
body 4 which is attached by means of a bolt 5 to a lower linking body 6 which is welded
to the bottom part of the valve 2.
[0016] In order to assist understanding, Figure 2 shows the sink of the invention without
any closure fitment, showing clearly that the valve 2 forms a single piece with the
rest of the sink.
[0017] As is obvious, the closure fitment of the valve does not necessarily have to be that
shown in Figure 1, but could for example be a plug which would be pressure-fitted
on the valve.
[0018] Independent of the object of the invention will be the materials used in manufacture
of the sink components, the shapes and dimensions of same and all accessory details
which might be presented, as long as they do not affect its essential nature, which
is set out in the attached claims.
1. Sink for kitchens, bathrooms and the like, which is made up of a body (1) whose lower
part includes a valve (2) provided with a plurality of orifices (3) which allow water
to pass towards a drainage pipe, characterized in that said valve (2) is formed of
a single piece with the rest of the sink body (1), said valve (2) being a cavity provided
with a plurality of orifices (3) formed in the bottom of the body (1).
2. Sink for kitchens, bathrooms and the like, as claimed in Claim 1, characterized in
that said valve (2) includes a movable closure fitment (4) which in a first position
allows water to pass through the orifices towards the drainage pipe and in a second
position closes off the passage of water.
