Description

ODOR EXTRACTING SYSTEM FOR WATER CLOSET
Bad odor extracting system from water closet through
double suction
TECHNICAL FIELD OF THE INVENTION.
The subject of this invention is a system to extract bad odours from water closet, through double suction. Unpleasant smells from faeces are removed through a double suction and expelled immediately in the atmosphere.
BACKGROUND OF THE INVENTION:
Until now to change air in the bathroom after use people had to open a window or use an aspirator, but the unpleasant odours remained in the air until there was a complete change of air. This is certainly a problem regarding both domestic bathrooms and bathrooms in public premises such as hospitals, restaurants etc.
To solve this problem the international patent application WO0111153 describes an extracting system for water closet odours, such a system aspirates odours from water closet with a pipe installed from the water closet to the roof of the building to expel to the unpleasant odours into atmosphere thus maintaining the water closet fresh and hygienic. The system described in the international patent application WO0111153 represents an improvement in comparison to what was done in the past although the following drawbacks are present: - When we are in an ambient with low pressure, the system cannot suck the unpleasant odours completely from the room where the water closet is;
. - the system, to be installed, requires a pipe, acting as a chimney, which must be higher than the ridge of the roof;
- the system cannot be installed cheaply in existing buildings as the cost of realization of the chimney is rather high;
- it is impossible to insert any filter in the system as this would reduce aspiration capacity;
- the system does, not guarantee 100 % of efficiency because its low aspiration capacity.
The principal aim of this invention is to produce a system for the extraction of unpleasant odours from the water closet through double suction, characterized by the fact that it comprises two pipes one applied to the water closet bowl and the other to the water closet seat, that the two pipes have holes in internal middle section for aspiration; that the holes of the pipe applied to the water closet bowl correspond to an equal number of holes in the upper border of the water closet bowl, that the aspiration in both pipes is carried out by an aspiration pump.
The system of the present invention can easily be installed both in new and existing building at lower cost and with greater efficiency compared to the old system. Another characteristic is given by the fact that the aspiration pipes are in semi-rigid rubber to guarantee that pipes are protected against rotting and damage from acid, making them easy to clean with any type of acid or detergent.
Another characteristic is given by the fact that the semi-rigid rubber pipe is inserted inside the groove of the upper border of the water closet bowl through two holes made one on the right side and one on the left side of the outflow water pipe.
Another characteristic is given by the fact that the two holes, after insertion of the two aspiration pipes, are hermetically sealed. Another characteristic is given by the fact that the ends of the semi-rigid rubber aspiration pipe on the external rear side of the water closet bowl are equipped each one with a valve to prevent aspiration of liquid. Another characteristic is given by the fact that the ends of the semi-rigid rubber aspiration pipes immediately after the valves are joined in a single central pipe in semi-rigid plastic which leads to the aspiration motor. Another characteristic is given by the fact that the pipe which takes the aspirated air out of the building comes out of the aspiration motor. Another characteristic is given by the fact that near the above-mentioned junction of the ends of the aspiration pipes there is deodorant filter which can be changed and reloaded. Another characteristic is given by the fact that the aspiration pipe under the water closet seat, in semi-rigid rubber is fitted into the supports of the seat itself.
Another characteristic is given by the fact that the supports of the seat have a central groove which allows the passage of the aspiration pipe.
Another characteristic is given by the fact that the two aspiration pipes are an integrating part of the water closet bowl and of the water closet seat.
Another characteristic is given by the fact that the holes in the bowl have a rectangular or trapezoidal shape to increase the volume of air aspirated and to cover a greater surface of aspiration.
Another characteristic is given by the fact that the holes in the bowl which have a rectangular or trapezoidal shape are made with nozzles which fit the exiting holes in the upper border of the bowl.
Another characteristic is given by the fact that the holes of the bowl are made with nozzles which fit the exiting holes in the upper border of the bowl and that the nozzles have a circular-shaped hole.
Further characteristics and advantages of the invention will be more evident through the description of the preferred but not exclusive realisation methods, of the machine itself, illustrated, just as an indication, but not as a limitation with the aid of the enclosed drawings

With reference to fig. 1 the suction system is formed by a semirigid rubber circular pipe that has two ends parts. Along the inside middle part it has some holes at a certain distance one from another to aspirate air from the water closet bowl. This rubber pipe is inserted inside the groove of the upper border 1 of the water closet ( fig. 2 ), through two holes that are on the external rear side of it, exactly one on the right and the other one on the left of the water outflow pipe ( fig. 3 ). After the passage of the two suction pipes, the two holes are hermetically sealed to prevent air from passing from the outside, thus impairing the functionality of the system. The water closet bowl border has holes 4 that are on its inner side (fig. 4). These holes must correspond with the aspiration holes 5 (fig. 5), that pass inside, and they are positioned at the same distance one from another; naturally they have the function to let the aspirate air pass by means of a suction motor.
The suction, pipes on the rear side of the bowl have two valves 3 to prevent suction of liquid (one at each ends) that are joined with special fittings (fig. 5). The valves 3 have the function of preventing suction should accidental passage of liquids occur. If liquids should enter into the circuit they would fill the valves-pocket causing upward pressure of the membrane positioned insjde the valves thus blocking the suction; in such a case, the valves must be emptied, disconnecting the junctions near them.
The pipe that comes out from each valve 3 is connected to the central pipe
6 (fig. 5), which leads to the suction motor; the central pipe 6, like the other elements of the suction system, can be made of a semi-rigid plastic. This pipe 6, is enclosed in the wall or can pass along the wall for the length necessary to reach the suction motor which is placed on the same wall of the toilet room near the water closet bowl.
The length of this pipe depends on the position of the motor. The motor suction works through a switch that can be positioned near the water closet bowl.
The suction pipe 7 has the same characteristics of the pipe inserted into
the border 1, and can be positioned under the water closet seat (fig. 6). The plastic pipe is positioned on the lower part of the water closet seat, and is fitted into the supports of the water closet seat; these supports must have a bridge shape (fig. 7) to allow the pipe to go through (fig. 7). Like the suction pipe inside the border of the water closet bowl the pipe positioned in the lower part of the water closet seat has holes placed at a certain distance one from the other to aspirate unpleasant odours. The ends of the pipe, on the rear side of the seat, i.e. on the outlet pipe, are connected with suitable junctions to the main pipe 9 which are already connected to the ends of the pipe inserted in the border of the bowl (fig. 8). The two pipes thus connected, increase the suction force because they act on all the air in the water closet bowl preventing the outlet from water closet of unpleasant odours produced in it.
The final part of the pipes, near the junction of the two suction pipes, has an internal deodorant filter, which can be change and reloaded, to avoid the outlet of unpleasant odours from water closet. Finally this pipe is connected to the suction motor 8 positioned on the nearest wall to the bowl. Besides, the motor having an outflow pipe will take the air aspirated from the water closet bowl outside the building. The suction holes can have rectangular or trapezoidal shape (fig. 9) that can be made directly in the border of the water "closet bowl or this shape can be realized with nozzles 9 which are inserted in the holes of the upper border of the water closet bowl, to connect the border with the suction pipe. (fig. 10-11) The suction pipe 7 can be inserted in the water closet seat and in the water closet bowl and instead of nozzles with rectangular or trapezoidal shape, nozzles 10 (fig. 12-13) with circular shape can be inserted. This invention is not limited to the representation given by the figures but can be perfected and modified by men expert in the art without altering the aim of the patent.
