Definitions
- the present invention relates to a device ensuring on the one hand an extraction of air from a room, and on the other hand, an extraction of stale air contained in a bowl of a sanitary appliance, in particular of a toilet.
- Air extraction systems from a room are well known. These systems draw in a quantity of air to discharge it to the outside. Such systems thus ensure renewal of the air in the room and therefore ventilation of the air in the room.
- None of the known systems allows both efficient extraction of stale air from the bowl via the distribution flange, and efficient extraction of air from the room by not passing through the distribution flange of the bowl.
- the invention therefore relates to a device for extracting the stale air located in the bowl by the rim or water distribution channel in the bowl, and at the same time an air extraction from the room in which is located the sanitary appliance, this air in the room not passing through the rim or water distribution channel of the bowl.
- the device according to the invention, details thereof or embodiments thereof are described in the claims.
- Such a device thus makes it possible to reduce the need to place a separate or additional ventilation system of one or more premises, or even to eliminate the need to place a separate or additional ventilation system of one or more premises.
- the device according to the invention thus allows one or more advantages chosen from: energy saving (a single motor for the aspiration of odors and ventilation; advantageous aspiration of air from the premises at the level of the bowl, this air being less hot than the air adjacent to the ceiling), ensuring elimination of odors at the source (no more deodorizing products are required), good evacuation of odors (the odors of the bowl are mixed with a volume of air passing not by the rim of the bowl, this ensuring that odors cannot remain in the tank and / or the exhaust duct), ensure cleaning of the exhaust air duct (s) by actuating the flushing (no deposit of dust in this or these pipes, non-proliferation of mites or other parasites in this or these pipes, hence reduction of allergy problems), maintenance of a sufficient water level in the siphon after
- the same system thus allows an extraction of a sufficient volume of air to ensure a sufficient renewal of air in the room (or ventilation of the room) and an efficient extraction of stale air or odors contained in the bowl.
- This system is of simple design and, in these best embodiments, does not require the drilling of holes in the walls for the passage of exhaust duct.
