Technical Field
[0001] Present invention relates to a washbasin that is a ceramic sanitary requisite with
two sinks, upper and lower, in a unibody providing an ergonomic use.
State of the Art
[0002] Purificatory characteristic of the water and its nature that represents purity have
been of the essence for various religions throughout the history and it is known to
be used in religious rituals. Splay vessels in which the water is accumulated after
washing hands, are known to be the first sample of the sinks used today.
[0003] The necessity of washing hands particularly before meals has been noticed through
experiencing various diseases in the past and a variety of studies have been conducted
on the mediums needed during the washing of the hands.
[0004] Initially, there were concave designs made out of various materials in which the
water poured from utensils such as ewers or buckets was accumulated. These concave,
shallow designs that were made out of materials such as copper and aluminum form the
basis of sinks that we use today. The fact that these designs needed emptying after
every hand or face wash constituted a disadvantage for the users.
[0005] Hand washing initially carried out with containers like ewers or buckets required
another person for pouring the water. This situation has constituted difficulties
for people who would like to wash their hands on their own and led users to seek various
solutions.
[0006] For the action of hand washing, the necessity of carrying water from structures such
as wells and fountains came to existence and this has constituted disadvantages for
the people. As a result of these disadvantages, subsequently to the necessity of carrying
the water to usage areas through different ways, a variety of studies have been carried
out. Thus, by adding the plumbing system to the designs known as basin, a technical
feature has been introduced. The improved plumbing system solved the problem that
necessitated the constant emptying of the wastewater that accumulated in the sinks
and discharging of wastewater through the plumbing system was achieved. With the technical
features brought in, sinks have begun to provide the user an ergonomic and comfortable
use.
[0007] There are various types of washbasins that we use regularly in our everyday lives.
These are usually wall mounted, mounted on furniture or typically located above or
below the counter. Having said that, these washbasins are manufactured as part of
certain standards and again put into the service of users within the scope of certain
standards. This situation causes various problems.
[0008] Because standard washbasin heights are higher than children's heights, children who
wish to wash their hands are either lifted up to the height of the washbasin by adults
or utilize stools to reach the washbasin. Without having the assistance of an adult
or a stool to reach the washbasin, children are having difficulties while washing
their hands or brushing their teeth.
[0009] Washbasins used in the state of the art are also constituting difficulties for elderly
and overweight individuals in the event that these individuals desire to wash their
hands and feet in terms of reaching standard washbasin heights. Additionally, standard
washbasin heights are also a challenge for individuals with disabilities.
[0010] As a result of the preliminary examinations conducted in the state of the art, it
has been found out that there are washbasins that contain two or more sinks. Even
though washbasins made out ceramic material that have two interconnected sinks located
next to and below of one another provided solution for feet washing problem, they
constitute disadvantages because they occupy a large space and are difficult to assemble
in tiny areas.
[0011] The utility model bearing number "
CN202925629U" relates to a washbasin that comprises of a large sink on the left side and a smaller
one on the right. Sinks of the said washbasin are made out of steel material and they
are located side by side. The said washbasin contains one faucet and two drains for
wastewater. While the sink located on the left side is used for activities like dish
washing, the smaller sink on the right side is used for washing ingredients (e.g.
salad ingredients) that require precision during the cleaning phase.
Advantages of the Invention
[0012] The object of the invention is to provide a developed washbasin structured in a unibody
that comprises of overlapping two sinks of which the below sink has a lower standard
height that will allow children to wash their hands and brush their teeth conveniently.
[0013] Another object of the invention is to provide a washbasin that will allow the elderly
and overweight individuals to wash their hands and feet comfortably.
[0014] Another object of the invention is to provide a developed washbasin structure that
will allow individuals with disabilities who can't reach the standard washbasin height
to carry out activities like washing their hands.
[0015] Another object of the invention is to allow adults to keep carrying out actions such
as hand washing, tooth brushing through the standard height sink contained in the
washbasin.
[0016] Another object of the invention is to provide a unibody washbasin that will take
up the same amount of space in the mounting area as one sink by installing upper and
lower sinks of the washbasin in an overlapping way.
[0017] Another object of the invention is to eliminate the possibility of discomfort that
the lower sink might constitute for the person who uses the upper sink by installing
lower sink that the washbasin comprises rearwards.
[0018] Another object of the invention is to eliminate the necessity of reaching out to
the clean water faucet for activities such as hand washing for the person using the
upper sink by designing the edge of the sink in rectangular, square or crescent shape
concave to the inner reservoir of the sink.

[0021] The present invention relates to a double-sink washbasin (10) structure that has
a lower sink (200) located under the upper sink (100) and an upper sink (100) that
allows use of multiple sink washbasin in the field of single sink washbasin for young,
adult, child, elderly and disabled individuals.
[0022] Double-sink washbasin (10) can be manufactured out of ceramic, porcelain, steel,
glass, wood, natural stone, marble or Corian materials and preferably made of ceramic
material. Double-sink washbasin (10) is particularly developed for the use of the
children, elderly and individuals with disabilities and can also be used as a medical
requisite. Mounting of the double-sink washbasin (10) is made with wall-hung mounting
system. Double-sink washbasin (10) comprises a single piece upper sink (100), a lower
sink (200) positioned under the upper sink (100), and a coupling piece (300) that
establishes the connection between the upper sink (100) and the lower sink (200) .
[0023] Upper sink (100) comprises upper sink faucet (110) which provides fresh water to
the user and can be in various shapes, wall mounting part (120) for installing the
double-sink washbasin (10) to the area of use, upper sink drain (140) for discharging
of the wastewater from the double-sink washbasin (10) pursuant to the activities such
as washing hands, brushing teeth, upper sink overflow hole (130) for preventing overflow
of the water accumulated in the upper sink (100) due to various reasons such as clogging
of the upper sink drain (140), upper sink drain pipe (150) for transferring the wastewater
to systems such as sewage system through the upper sink drain (140) and upper sink
edge (160) which can be in rectangular, square or crescent shape for providing support
to upper sink users and convenience while they wash their hands without reaching out
to the upper sink faucet (110).
[0024] The upper sink (100) can be in various forms but manufactured preferably in an elliptical
shape. In the top view of the double-sink washbasin shown in the Figure 2, the upper
sink (100), upper sink edge (160) which is the side that the user is on while using
the double-sink washbasin (10) is seen in an elliptical form and concave to the inner
reservoir of the upper sink (100) . The upper sink edge (160) which is in a concave
form that allows convenience for users to reach the faucet is positioned on the side
while the user is using the double-sink washbasin (10). In the rear side of the upper
sink edge (160) of the upper sink (100) there is the wall mounting part (120) which
assumes the task of mounting of the upper sink (100) to the wall. Upper sink drain
pipe (150) is on and under the same vertical axis with the wall mounting part (120)
and positioned between the upper sink (100) and the lower sink (200). Upper sink faucet
(110) is on the same horizontal axis with the wall mounting part (120) of the upper
sink (100) and positioned closer to the wall and between the wall to which the double-sink
washbasin (10) is mounted and the upper sink edge (160). Upper sink overflow hole
(130) and upper sink drain (140) are located inside the reservoir of the upper sink.
When examining at the upper sink (100) parallel from the height of the upper sink
edge (160), in terms of height from top to bottom; upper sink faucet (110), below
that the upper sink edge (160), below that the upper sink overflow hole (130), below
that wall mounting part (120), below that upper sink drain (140) located inside the
upper sink and at the bottom the upper sink drain pipe are arranged in order.
[0025] The lower sink (200) comprises lower sink faucet (210) which can be in various forms
to provide water to the user, lower sink drain (230) for discharging the waste water
from the double-sink washbasin (10) pursuant to usage, lower sink overflow hole (220)
for preventing overflow of the water accumulated in the lower sink (200) due to various
reasons such as clogging of the lower sink drain (230), lower sink drain pipe (240)
for transferring the wastewater to systems such as sewage system through the lower
sink drain (230), lower sink edge (250) on which the lower sink(200) user rests while
using the lower sink (200) and lower sink wall mounting part (260) where the lower
sink (200) comes into contact with the wall.
[0026] The lower sink (200) is in a unibody form with the upper sink (100) connected with
a coupling piece (300) produced out of ceramic material. The lower sink (200) and
the upper sink (100) are positioned on the same vertical axis. When the double-sink
washbasin (10) is viewed from the side by leaving the wall that it's mounted on the
left, the conjunction view of the lower sink (200) and the coupling piece (300) resembles
a reversed letter "J" shape. Because the lower sink (200) is in a unibody form with
the upper sink (100) and the mounting of double sink washbasin (10) to wall is done
through the wall mounting part (120) located on the upper sink (100) there is no mounting
part on the lower sink (200). However, there is the lower sink wall coupling part
(260) where the lower sink comes (200) into contact with the wall. The lower sink
faucet (210) is positioned on the coupling part (300). In the inner reservoir of the
lower sink where the wastewater is accumulated, there is the lower sink overflow hole
(220) and the lower sink drain (230). The lower sink overflow hole (220) is on the
same horizontal axis abreast with the wall coupling part of the lower sink (200).
The user that utilizes the lower sink (200) of the double-sink washbasin (10) uses
the double-sink washbasin (10) by means of resting on the lower sink edge (250). Lower
sink drain (230) is located on the bottom of the inner reservoir of the lower sink
(200). The lower sink drain pipe (240) that assumes the task of transferring wastewater
through the lower sink drain (230) to the sewage system is positioned lower than the
bottom edge of the double-sink washbasin (11) and higher than the wall.
[0027] As it is shown in Figure 1 when looked at the lower sink (200) from the lower sink
edge (250) on a horizontal axis, at the top lower sink faucet (210), below that the
lower sink edge (250), lower sink overflow hole (220) and lower sink wall coupling
part (240), below these the lower sink drain (230) and at the bottom lower sink drain
pipe (240) are arranged in order.
[0028] The lower sink (200) was manufactured in a smaller size compared to the upper sink
(100) in order not the constitute any difficulties during the use of the upper sink
(100). As it is shown in Figure 1, compared to the upper sink edge (160), the lower
sink edge (250) is positioned closer to the wall on the vertical axis.
[0029] Because the double-sink washbasin (10), the upper sink faucet (110) to which the
clean water reaches to from the wall that it's mounted on and the lower sink faucet
(210) cover the upper sink drain (140) and the lower sink drain (230) that are utilized
for discharging the wastewater to the sewage system, the visual pollution is prevented.
[0030] Washing sensor connection holes located on upper sink faucet (110) and the lower
sink faucet (210) where the clean water enters in and coupling parts of the lower
sink drain pipe (240) and the upper sink drain pipe (150) that assume the task of
transferring the wastewater to sewage systems are in accordance with standards of
Turkish Standards Institute.
[0031] The upper sink faucet (110) and the lower sink faucet (210) where the clean water
comes into the system can have both mechanical and sensor-fitted designs. Double-sink
washbasin (10) can be manufactured with vitrified ceramic casting molds and on casting
tables. Having said that, the method for double-sink washbasin (10) comprises the
