Description

    Technical Field
  • Present invention relates to a washbasin according to the preamble of claim 1 and that is a sanitary requisite with two sinks, upper and lower, in a unibody providing an ergonomic use. The sanitary requisite is preferably ceramic.
    • State of the Art
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Another examples of double-sink washbasins are disclosed in US1 616 313 A and FR1 357 113 A .
    • Advantages of the Invention
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • The objects are achieved by a unibody double-sink washbasin according to the appended claims.
