Description

ODOR EXTRACTOR

FIELD OF THE INVENTION

[0001] The disclosed embodiments relate to odor extraction. The disclosed embodiments further relate to a vacuum filtration and ventilation system for a toilet. The disclosed embodiments also relate to an odor extraction system with an integrated air filter.

BACKGROUND

[0002] People consider their excremental functions private. While private, restrooms in homes and public restrooms fail to ventilate odorous air. The offensive odor is typically diffused throughout the restroom and other indoor spaces. Those in close proximity to the restroom are subjected to offensive odors for prolonged periods of time. Previous attempts to compensate for stagnant restroom air using air fresheners, for example, fail to properly disperse odors. Air in the restroom often becomes contaminated prior to reaching exhaust fans installed in a restroom's ceiling. An additional problem with the common toilet is that odors accumulate before the toilet can be flushed. Additionally, conventional flushing toilet bowls release a fine mist or aerosol. Such a mist or aerosol contains objectionable odor as well as potentially harmful bacteria and viruses spread throughout the adjacent area.

[0003] Therefore, a need exists for an improved toilet ventilation system and method to efficiently remove odors before disbursement into the restroom and areas proximate to a restroom.

SUMMARY

[0004] The following summary is provided to facilitate an understanding of some of the innovative features unique to the embodiments disclosed and is not intended to be a full description. A full appreciation of the various aspects of the embodiments can be gained by taking the entire specification, claims, drawings, and abstract as a whole.

[0005] It is, therefore, one aspect of the disclosed embodiments to provide for an improved odor extractor.

[0006] It is another aspect of the disclosed embodiments to provide for an improved vacuum filtration and ventilation system for a toilet.

[0007] It is a further aspect of the disclosed embodiments to provide for an improved odor extraction system with an integrated air filter.

[0008] The above and other aspects can be achieved as is now described. An improved odor extracting apparatus and system are disclosed. The disclosed embodiments provide an exhaust vacuum for a toilet with associated venting installed through existing walls, windows, ceilings, or other outlets. The exhaust apparatus suctions air and aerosol particles from the toilet bowl to prevent lingering odor in the restroom and areas proximate to the restroom. Embodiments of the disclosed odor extractor are installed either independently of the toilet seat or incorporated in the toilet seat manufacturing process. Exemplary models fit any make of toilet seat and are interchangeable between toilet seats. The disclosed odor extractor is low in noise and vibration.

[0029] Current wall or ceiling ventilation fails to instantly extract odors and smells. Instead, odors disburse throughout the restroom and/or nearby rooms, leaving a feeling of discomfort to the user's own smells. The disclosed embodiments provide an exhaust fan and/or exhaust vacuum and odor extractor for a toilet. The odor extractor's nozzle is located between the toilet and the seat of the toilet, subsequently connecting ventilating conduit to an exhaust. The associated ventilation system is located on at least one side of the toilet. Embodiments of the disclosed odor extractor further comprise an extraction nozzle which has an air flow groove located in front thereof. The extraction nozzle is placed as physically close as possible to the source of odors, i.e., between the toilet seat and the toilet.

[0030] A connector is located at the back of the extraction nozzle to connect the nozzle to an odor extractor duct. The duct is connected at the opposing end to an air extractor. The air extractor comprises a switch at the output of the extractor connected chute which expels odors from the toilet towards the outside environment. The exhaust fan operates via a manual switch or an automatic sensor that senses when a restroom user is close to the toilet. The automatic sensor can be located on the extraction nozzle, anywhere on the odor extractor apparatus or system, and/or anywhere in the restroom, either freestanding or mounted, to detect use entry and/or use of the toilet. The manual switch can be placed at the entrance of the restroom or located on a component of the disclosed odor extractor apparatus or system. The manual switch can be activated by a restroom user prior to using the toilet or during use of the toilet. The associated vent pump is preferably an electric pump with a turbine engine. The disclosed odor extractor is low in noise and vibration.

[0031] FIG. 1 illustrates a schematic view 100 of an odor extraction apparatus, according to a preferred embodiment. The odor extractor apparatus 101 , installed between the toilet bowl and toilet seat, is electrically operated and suctions air, aerosol particles, and/or bacteria through an open vacuum space 102 of the odor extractor 101. Vacuum space 102 of odor extractor apparatus 101 is installed towards a toilet bowl and sucks in air and particles as indicated by the arrows in FIG. 1. The odor extractor system, method , and apparatus suction an air stream in close proximity to the toilet bowl and odor source, thus preventing odor from escaping the toilet bowl area and surrounding restroom area. When the odorous particles are removed from the source through the vacuum space 102, lingering odor does not permeate the restroom and surrounding spaces. Embodiments of the disclosed odor extractor are installed either independently of the toilet seat through holes 103 and 104, or incorporated in the toilet seat manufacturing process.

[0032] To install the apparatus on a toilet, holes 103 and 104 are sized to fit through existing hardware on most standard toilet seats. Exemplary models fit any make of toilet seat and are interchangeable between toilet seats. Manual switch 105 can be depressed by the user of the toilet to start the vacuum while the toilet is in use. Vent 106 connects the odor extractor 101 to vacuum pump 107. Vacuum pump 107 is attached to an exterior vent 108 to direct odor and particles out of the restroom area, through venting installed in a floor, ceiling, wall, or window, for example.

[0033] FIG. 2 illustrates an exemplary pictorial illustration 150 of the odor extraction system, according to an embodiment. The odor extractor apparatus 151 is installed on toilet 152. With the odor extractor vacuum placed between the toilet's 152 bowl and seat, the odor extractor vacuum is in close proximity to the odors to prevent escape in to the air of the restroom, while remaining sanitary.

[0034] Restroom odors are expelled towards the outside environment through a duct exhaust outlet by means of suction created by a pump interconnected to the odor extraction nozzle. FIG. 3 illustrates an exemplary schematic view 200 of the odor extractor system and vertical ventilation outlet 202, according to an embodiment. The odor extractor apparatus 201 is installed on toilet with a vertical ventilation outlet 202. Tank 203 is raised with the installed odor extractor apparatus 201 for illustrative purposes only. The vertical ventilation outlet 202 allows attachment of additional conduit to ventilate odors through a wall-mounted conduit or window-mounted conduit (not illustrated). For example, FIG. 4 illustrates a pictorial illustration 250 of an exterior wall-mounted, vertical ventilation conduit 252 connected to the odor extractor apparatus 251 , according to an embodiment. The exterior wall-mounted, vertical ventilation conduit 252 can extend the length of the wall through a hole in the ceiling to vent to an outside environment, or through multiple lengths of conduit in a multiple-level building. An exemplary pictorial illustration 300 of the window- mounted conduit 302 is illustrated in FIG. 5. The odor extractor apparatus 301 is mounted to the toilet and vents odors through vertical ventilation outlet 302 that spans the length of the exterior of a restroom wall. The conduit for the odor ventilation is preferably plastic or PVC. It is understood that the conduit or tubing can comprise any suitable material and is not limited to plastic embodiments.

[0035] FIG. 6 illustrates an exemplary schematic view 350 of the odor extractor system and horizontal ventilation outlet 352, according to an embodiment. Horizontal ventilation outlet 352 exits the odor extractor apparatus 351 and enters a hole in the restroom wall, as illustrated in an exemplary pictorial illustration 400 in FIG. 7. Ventilation occurs through additional conduit within the restroom wall or directly to an outside environment.

[0036] FIG. 8 illustrates an exemplary schematic view 450 of the odor extractor system, floor-facing ventilation outlet, and manual switch, according to an embodiment. Ventilation

451 for the odor extractor faces towards the restroom floor to exit through the floor. Manual switch 452 to operate the odor extractor is depressed before or during use of the toilet. An automatic sensor 501 , as illustrated in exemplary schematic view 500 in FIG. 9, can automatically detect when a user enters the restroom or is in close proximity to the toilet and starts the odor extractor vacuum. The user does not have to depress a manual switch

452 when automatic sensor 501 operates the odor extractor system. The odor extractor system saves energy when operated on an automatic sensor as it turns on only when the toilet is in use and for some time after toilet use, based on a programmed operation time.

[0037] FIG. 10 illustrates an exemplary schematic view 550 of the odor extractor system and associated air filter 551 , according to an embodiment. In addition to ventilating air, the disclosed embodiments filter the water via the associated air filter 551 that passes through the toilet. FIG. 1 1 illustrates an exemplary schematic view 600 of the odor extractor system and integrated filter system 601 , according to an embodiment. The odor extractor system may integrate a filter system 601 , with a filter pad 602 and a motor 603. FIG. 12 illustrates an exemplary schematic view 650 of the odor extractor system and filter assembly 651 , according to an embodiment. The odor extractor apparatus 653 is integrated with a separate filter assembly 651 and a filter pad 652.
