1. Field of the Invention
This invention relates to apparatus for preventing the spread of foul odors and various germs causing illness when a toilet or water closet is used to satisfy a basic physical need of a person for elimination of waste, and, more particularly, to such apparatus eliminating foul odors by sucking air from a bowl of a water closet.
2. Summary of the Background Art
Known solutions related to the elimination of foul odors and germs causing illness when a person satisfies a basic physical need for elimination of waste mostly rely on the ventilation of an entire toilet room, or on the rinsing, filtration, cleaning, and disinfecting of the water closet, etc. The ventilation of an entire room using a ventilator in the ceiling or in on a toilet wall to exhaust air is often ineffective due to the considerable volume of the space being exhausted without an inward flow of fresh air. Rinsing, cleaning and disinfecting ecologically burden the environment with chemicals and eliminate the problems of the foul odors and micro-organisms too late, since these problems remain in the air and spread within the room even while the person satisfies his basic physical need for elimination. When these known solutions are combined with ventilation and filtration of the air in the water closet, the process becomes technically too complex, with ventilation machines requiring space in or on the water closet for fitting up and operation.
Slovenian Patent No. SI 21277 describes a solution for the direct elimination of the foul odor by sucking air from the seat or cover of the water closet with the removal of a minimal volume of air effectively eliminating the spread of the foul odor and of micro-organisms within the room while saving energy. One problem remaining unsolved is related to the sucking of air through two tubes from the seat of the water closet, where the volume of air to be removed is relatively high, but where the effectiveness of sucking the air away is relatively low, because of the disproportional and unsymmetrical disposal of both tubes in water closet vertex. Other problems remaining unsolved by sucking air from the seat of water closet arise from the facts that the seat must be too thick and that it becomes impossible to use a protective cover on the seat for hygienic reasons without reducing the effectiveness of the system of sucking air to remove the foul odor.
