FR2618816A1 - Air-purifying equipment usable on all WC seats - Google Patents

Abstract

A device extracting and filtering air drawn from the WC bowl usable on all types of WC seats. It comprises a series of ventilation apertures 1 fixed to the WC seat 2 under the cover 4. An electrical switch 3 positioned in the hinge of the cover 4 starts the electrical extract motor 5 as soon as pressure is applied to the cover 4. The extract motor, whose operation is controlled by a voltage-varying device 8 and a relay/time switch 9, carries the extracted air over a filter or a filtering-deodorising unit where the air is purified and deodorised before being returned to the room. The device according to the invention is a product for extensive consumption.

Description

The present invention relates to a device which sucks the stale air from inside a toilet vase and purifies it by passing it through an activated carbon filter or an active carbon filter / odorant filter complex.

Currently forced ventilation systems and / or the use of air fresheners do not prevent stale air from spreading in the room.

The device according to the invention overcomes this drawback by sucking the stale air near the source.

I1 includes a battery of air intakes, an electric vacuum motor which sucks the stale air from the toilet vase through the air intakes and an activated carbon filter or complex of filters (activated carbon coupled with a odor filter) having the role of purifying and odorizing the air rejected in the room
The battery of air intakes, adaptable to all types of WC chairs is fixed on the WC vase and allows the absorption of stale air, during the use of the WC, without interfering with the flushing or cleaning the vase.

The battery of air intakes is fixed in the rear part of the WO chair, under the slaughterhouse which, by its construction is intended to protect them and to ensure the starting of the vacuum motor.

The electric motor, silent and waterproof operates at 12V and is triggered as soon as a person sits on the slaughterhouse, thanks to an electrical contact incorporated in the hinge thereof.

A timer relay keeps the engine running for a variable period of time from 30 seconds up to 3 minutes, depending on the choice, after the pressure on the slaughterhouse stops.

A voltage regulator makes it possible to adjust the operation of the motor, its suction power by eliminating the inconveniences caused by the accelerated circulation of air.

The activated carbon filter or other absorbent filter and the odorant filter constitute a compact complex, the existence of the odorant filter being however not obligatory for the purification of the air.

 I1 will be placed before or after the vacuum motor, on the path of the air driven by it which, by crossing it will be filtered, purified and odorized.

When unusable, the filter / filter complex will be replaced.

Figure 1 shows the device according to the invention installed on an existing toilet chair.

Figure 2 shows a variant of this device.

Figure 3 shows a variant of this device.

The device shown in Figure 1 has air intakes (1) attached to the existing toilet chair (2). An electrical contact (3) provided in the hinge of the slaughterhouse (4) starts the electric vacuum motor (5) as soon as a person sits on the slaughterhouse (4). The stale air sucked in by the air intakes (1) arrives in the vacuum electric motor (5) through the flexible connections (6). The electric vacuum cleaner motor (5) projects stale air into the activated carbon filter or the combination of filters - active carbon filter - odorant filter (7) from which it comes out purified and odorized.

The voltage regulator (8) regulates the operation of the electric motor (5) therefore the air flow sucked. The relay / timer (9) ensures the operation of the vacuum cleaner electric motor (5) for a variable period of time from 30 seconds to 3 minutes, depending on the choice, after the pressure ceases to be applied to the slaughterhouse (4). The transformer (10) supplies the vacuum cleaner electric motor (5) with 12V, without danger to the user.

In the embodiment according to FIG. 2, the activated carbon filter or the active carbon filter - odorant filter complex (7) is located before the vacuum cleaner electric motor (5) in direct connection with the flexible connections (6).
In the embodiment according to Figure 3, the toilet vessel (11) is designed having the air intakes (1) integrated in its construction.

All the other components of the device according to the invention are subsequently mounted on the WC vessel (11), their operation being the same.

A variant of the device according to the invention uses the same slaughterhouse for absorbing the stale air from the toilet vase, the air intakes being housed in the slaughterhouse.

The device according to the invention is a widely consumable product which can be used wherever there is a toilet chair.
