Description

The most widely spread method for removing unpleasant scent in the toilets is through dispensing perfumes and fragrances from a variety of substances – liquids, oils, gels, etc. The dispensers could be manual or automatic, working at time intervals or on the basis of photocells. Regardless of the type of fragrance, this approach does not actually treat or prevent unpleasant odor, it basically decreases its strength while the latter is being sucked away from the room with the help of the ventilation system.
In contrast to the above, the present R&D result captures the gases directly from the toilet bowl and does not allow their diffusion into the toilet room. The gases are sucked away with the help of the gas-extracting system that is mounted to the lavatory pan seat. The seat itself is designed in a way that allows not for the gases to leave the toilet bowl and penetrate into the bathroom. It has a number of openings and channels in the internal rim of the lower part of the toilet seat, through which the gases are captured by the system, extracted and chemically filtered and processed.

Solution

by capturing the gases from the toilet bowl directly, the room is kept clean and has no nead for additional fragrancing. The main challenge lies in the chemical treatment of the gases captured, which are afterwards released in the bathroom. Hence the volume of air that has to be sucked away is much smaller than if the gases are let out in the entire toilet room. Moreover, the general ventilation systems simply suck away the air and release it in the chimneys. Whereas the odor-extracting system of the present product applies chemical treatment of the gas captured.
The solution provided by this R&D result is innovative for the territory of Bulgaria. It is also claimed by the researcher to be a world innovation.
Here is an analogue of the present product.
An internet search shows the existence of a number of similar products, though none of them has a completely identical design with that of the present R&D result. Most of the seats already developed (as shown in the figure above) have their openings and channels on the lower surface of the toilet seat and thus the gases may, though partially, penetrate into the room. The researcher claims (as shown in the figure below) that them being placed on the internal rim of the lower part of the seat ensures that they do not leave the toilet pedestal and thus 100% of them are sucked into the odor-extracting system, to which the pan seat is connected.

Furthermore, the extracted gas, after having gone through the chemical filter, is released directly into the bathroom, and there is no need for connecting the outlet to the sewage system
