Dual flush cistern
Introduction
It is called toilet, toilet, toilet,[a] toilet, sanitary, bacinete, bacín, poceta, or wáter,[3] to the sanitary device used to collect and evacuate solid and liquid excrement of humans towards a sanitation facility and that prevents, through a clean water siphon system, the escape of unpleasant odors from the sewer or sewer to inhabited spaces. Odorless means that it does not smell.[4].
Toilet bowls are generally made of porcelain, but also stainless steel and any other smooth, waterproof material. The technology used for modern toilets varies; They are usually made of ceramic (porcelain), concrete, plastic or wood. Newer toilet technologies include dual flush), low flush, heated toilet seat, self-cleaning, urinals, and waterless urinals. Japan is known for its toilet technology. Airplane toilets are specially designed to operate in the air. The need to maintain anal hygiene after defecation is universally recognized and toilet paper (often held by a toilet paper holder), which can also be used to clean the vulva after urinating, is widely used (as is the bidet).
In private homes, depending on the region and style, the toilet may exist in the same bathroom as the sink, bathtub and shower. Another option is to have a room for body washing (also called a “bathroom”) and a separate room for toilet and hand washing (bathroom). Public toilets consist of one or more toilets (and commonly single urinals or channel urinals) that are available for use by the general public. Products such as urinal blocks and toilet blocks help keep toilets smelling and clean. Toilet seat covers" are sometimes used. Portable toilets (often chemical "portable toilets") may be installed for large, temporary gatherings.
Historically, sanitation has been a concern since the early stages of human settlement. However, many poor households in developing countries use very basic and often unhygienic toilets, and almost a billion people do not have access to any toilet; They must defecate openly and urinate.[5] Or they must resort to a "flying toilet": a plastic bag. These problems can lead to the spread of diseases transmitted through the fecal-oral route, or the transmission of waterborne diseases such as cholera and diarrhea. Therefore, the United Nations Sustainable Development Goal 6 wants to "achieve access to adequate and equitable sanitation and hygiene for all and end open defecation free».[6].
