Toilet Equipped With Vacuum Cleaner

Abstract

The subject of the present invention is a specially shaped toilet which prevents the diffusion of contaminated “aerosol” into the environment by sucking it directly from the toilet basin by means of an electric aspirator placed inside the toilet itself, and expelling it into the sewer pipe through specially fitted ducts.

Claims

1. An improved toilet equipped with a vacuum cleaner, comprising: a suction intake appropriate for sucking away bad smells and gas containing aerosol bacteria or viruses present in a toilet basin during use; an outlet made in such a manner as to convey vacuumed aerosol into an intake duct connecting the toilet with a sewer; at least one aspirator connected through appropriate ducts to the intake duct and an exhaust duct; at least one one-way valve located along the exhaust duct or along the intake duct; and devices and means for activating the aspirator.

2. The improved toilet equipped with the vacuum cleaner of claim 1, wherein: the suction intake which provides communication between toilet basin and intake; a suction duct which connects to the suction intake, through which the suction duct vacuums away the water and aerosol bacteria or virus mixture present in the toilet basin and the suction duct by means of an electric aspirator; an electric aspirator which connects to the suction duct and the at least one aspirator, and the exhaust duct which connects to the electric aspirator joined through the outlet to the exhaust duct which opens into the sewer network.

3. The improved toilet equipped with the vacuum cleaner of claim 2, further comprising a button for activating the electric aspirator.

4. The improved toilet equipped with the vacuum cleaner of claim 3, further comprising pressure sensors which detect weight on a toilet seat, and which activate the electric aspirator responsively to detecting the weight.

5. The improved toilet equipped with the vacuum cleaner of claim 4, further comprising photoelectric cells which activate the aspirator in the presence of a person.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The toilet according to the present invention will be described hereinafter in an indicative but not limiting embodiment, provided with reference to the attached drawings, in which:

[0012] FIG. 1 shows a longitudinal section of the toilet according to the present invention alone, without the electric vacuum cleaner, the ducts, and the one-way valve, for explanatory purposes.

[0013] FIG. 2 shows a longitudinal section of the toilet according to the present invention complete with the electric vacuum cleaner, the intake and exhaust ducts, and the one-way valve.

DETAILED DESCRIPTION

[0014] According to the present invention, the toilet is shaped in such a way that toilet basin (1) comprises aerosol suction intake (2), whose opening is preferably positioned in correspondence with the lower part of the rim. The toilet also comprises a discharge channel (3) appropriately shaped. Suction intake (2) and discharge channel (3) are connected by means of ducts (6 and 8) to vacuum cleaner (7) capable of forcibly conveying the aspirated aerosol into toilet discharge duct (4) connected to the sewer.

[0015] Sanitary siphon (5) prevents the aerosol from returning to the environment through toilet basin (1). Similarly, one-way valve (9), placed, for example, along exhaust duct (8), prevents, when vacuum cleaner (7) is not in operation, the return of the aerosol and the fumes coming from the sewer network through suction intake (2) connected to toilet basin (1). As seen in FIG. 2, vacuum cleaner (7), connected to suction intake (2) through duct (6), sucks the bad odor and the aerosol containing bacteria and viruses from toilet basin (1). By means of duct (8), vacuum cleaner (7) introduces the aerosol containing viruses and bacteria into discharge channel (3), equipped with one-way valve (9), which opens into discharge duct (4) from the toilet connected to the sewer system.

[0016] The one-way valve (9) and plumbing siphon (5) prevent the bad odors and aerosol from returning into the environment.

[0017] Vacuum cleaner (7) can be activated using a separate control.

[0018] Alternatively, controls can be provided through automatic or semiautomatic controls, such as, for example, pressure sensors which detect weight on the toilet seat.

[0019] Conveniently, photoelectric cells which activate the vacuum cleaner in the presence of a person can be provided.
