Toilet bowl - an element of toilet equipment, used for defecation, voiding in a sitting or standing position. It is traditionally made of porcelite or other types of ceramics. There are also bowls made of plastic or stainless steel. It can act as an independent element of bathroom equipment as well as be part of the so-called toilet compact.
In 1596, John Harington (1560-1612) published a description of a self-built flush toilet that he had installed at his home in Kelston.
With the advent of the industrial revolution and the associated technological advances, the toilet began to emerge in a modern form. The most important advancement in plumbing was the siphon, invented by the Scottish mechanic Alexander Cumming in 1775 and still used today. This device uses standing water to seal the outlet of the bowl, preventing contaminated air from entering the sewage system.
To increase the comfort of use, as well as for hygienic reasons, a toilet seat, also called a toilet seat, or - in colloquial language - a toilet seat, is usually lowered over the edge of the bowl.
It is a rim-shaped seat that corresponds to the dimensions of the upper outline of the toilet bowl. The toilet seat can be composed of two interconnected parts: the seat and the lid enabling the closure of the bowl. The seat and cover are fixed on common hinges, the fixed part of which is connected to the toilet bowl. It can be made of plastic (ABS, duroplast, PVC), wood, HDF, stainless steel and others.
Connection to the sewage system
The toilet bowl is equipped with a siphon that connects it to the sewage system and prevents odor from the sewage system from entering the toilet, as well as a flushing system (flush). Thanks to these solutions, after draining the water, the contents of the shells are discharged into the sewage system.
In some countries, more and more amenities are used that improve both the hygienic conditions and the comfort of using this device: e.g. a toilet seat can be equipped with an additional bidet function, a heater to increase the temperature of the seat, disposable covers for the toilet seat, etc. In many countries they are used devices that, after appropriate programming, identify the user (e.g. based on body weight) and carry out various programs accordingly, e.g. washing, drying, releasing fragrances or sucking in unpleasant odors. All these improvements include the toilet seat and are unlikely to apply to the bowl as such.
