Description

Title: INTEGRATED TOILET BOWL WITH EXHAUST SYSTEM

FIELD OF THE INVENTION

This invention relates to a field of odor/impure/stale air removing system for toilet more particularly the system removes odor/impure air from the toilet bowls and diverts into a sewer line. BACKGROUND OF THE INVENTION

Now a day, we are using an exhaust fan as a mechanical ventilation device that helps to draw out stale and impure air from the toilet and bring in fresh air, thereby improving the quality of indoor air. Exhaust fans are typically ducted to the exteriors of toilet, through which bad indoor air/stale air/impure air can be removed from the interior of the toilet. The main drawbacks of the above technology are:

1. The exhaust fan has to remove large quantity of air from the toilet area.

2. The exhaust fan discharges unfiltered air into the atmosphere.

3. Before discharge, the stale air spread across the entire toilet area. Particularly in public toilet zone, the effect of the impure/stale air is more.

Several devices and methods have been proposed to address the above mentioned problems. The results, however, have been less satisfactory because the majority of the prior art discloses about treating stale /impure air inside a toilet bowl.

The prior art US 4,317,242 discloses about a device for the removal of foul air from toilet bowls and the like. The device comprises a conduit having an inlet opening and at least one outlet opening spaced from the inlet opening. The conduit has a hook shape and is capable of hooking over the rim of the toilet bowl and under the seat so that the inlet opening is within the bowl and the outlet opening is outside the bowl. The device also includes an air treatment means within the conduit, capable of improving the quality of foul air passing through it. The device also includes a battery-operable fan capable of drawing foul air out of the bowl via the inlet opening, along the conduit, through the air treatment means and out of the outlet opening. The air treatment means, optionally together with the battery, may be provided as a replaceable pack. The prior art needs frequent maintenance. If we consider public toilet, implementation of this technology is more complicate. Hence there is a need for a system to overcome the above drawbacks.

With a view to accomplish the above needs, the following solutions are provided in the present invention.

OBJECT OF THE INVENTION

The object of the invention is to provide an integrated odor/impure/stale air removing system for toilet.

Another object of the invention is to remove the stale/impure air from the toilet and divert into sewer line. Yet another object of the invention is to avoid discharging of unfiltered air into the atmosphere.

Yet another object of the invention is to provide a maintenance free system for stale/impure air removal.

Yet another object of the invention is to avoid diffusion of impure air across the entire toilet area.

Yet another object of the invention is to provide suction line and siphon/water lock line combined system for effective removal of stale/impure air from toilet.

Further object of the invention is to arrest the reverse flow of stale/impure air by using the siphon/water lock line as a reverse flow lock system. SUMMARY OF THE INVENTION

The present invention relates a system for removing stale/impure air from the toilet bowl region and diverting into sewer line. The system is placed between water flesh line and sewer line to observe/collect stale/impure air via water flush line and diverted into sewer line. The system comprises of suction line and siphon line. Each line includes inlet and out ports. The inlet of the suction line and siphon line are connected with the water flesh line of the toilet. The out let of the siphon line is connected with the sewer line. The out let of the suction line penetrates the siphon line and immersed within the water level of the siphon line. An impeller/fan of a suction motor or suction means arranged in the suction line. During the operation, the suction motor draws the impure air via water flush line and discharges the drawn impure air into the sewer line via outlet of the suction line and siphon line. Further, during the each water flushing action, the flushed water enters into the siphon line and forces the existing water in the siphon line for completely removing the observed/collected impure air and impure water from the system into sewer line. The siphon/water lock line acts as a reverse flow lock system. The system is controlled by a control system. The control system activates the suction motor based on plurality of sensing means.
