Description

FIELD OF INVENTION

The present invention relates generally to gas evacuation systems, more specifically but not by way of limitation, a radon removal apparatus that is operably coupled to an area underneath a residential or commercial structure wherein the radon removal apparatus functions to remove radon gas that accumulates underneath the structure and vent the gas to atmosphere.

BACKGROUND

Radon gas is a colorless, odorless and tasteless noble gas that is radioactive. Radon gas naturally occurs in small quantities as an intermediate step in the normal radioactive decay chains through which elements such as but not limited to thorium slowly decay into lead and other short-lived radioactive elements. Despite radon's short half-life, it is continuously being regenerated and as such its presence will remain long into the future. Radon gas is considered a health risk as it is typically the single largest contributor to an individuals background radiation dose. The presence of radon gas varies locally from region to region based on the geology of each region. Studies have shown that breathing air that has a high concentration of radon gas demonstrates a clear link to lung cancer. In the US, radon gas is the second leading cause of lung cancer behind cigarette smoking.

Radon gas typically enters a building through the soil through the lowest level in the building. Entry points can be cracks in foundations, construction joints and gaps around service pipes just to cite a few. Existing technologies for removal of radon gas include fan systems that are fluidly coupled to the ground underneath a building structure in at least one location. The fans are operable to exhaust the radon gas to the atmosphere and inhibit the radon gas from entering the building.

One issue with existing radon removal fans is their inability to have the blower mounted in an upright position in an inline pipe system. Existing technology does not promote the most efficient mounting of the blower and as such the removal efficiency. Additionally, most radon fans are mounted outdoors and as such are subject to humidity and temperature changes. The exposure to humidity and temperature changes results in accumulation of condensation in the system and existing technology lacks the elements to provide removal thereof. Lastly, exit vents of existing radon fans have a velocity of air traversing therethrough that is sufficient to create noise during operation which can be undesirable for homeowners.

Accordingly, there is a need for a radon removal system that includes a housing wherein the housing design provides the ability for an impeller disposed therein to be mounted in a vertical position and wherein the housing further provides drainage elements so as to facilitate the removal of condensation from the interior of the housing.

SUMMARY OF THE INVENTION

Referring in particular to FIG. 1, the radon removal apparatus 100 further includes a housing 10. The housing 10 is manufactured from a durable suitable material such as but not limited to plastic. The housing 10 includes a lower portion 12 and an upper portion 15. The upper portion 15 and lower portion 12 are mateably coupled utilizing suitable durable techniques. The housing 10 is separable so as to provide access to the blower assembly 50. The lower portion 12 includes bottom 13 and wall 14 wherein the bottom 13 and wall 14 are contiguously formed utilizing suitable techniques. The wall 14 is perpendicular in orientation from the bottom 13 and extends upward therefrom. While the housing 10 is illustrated herein having a lower portion 12 and upper portion 13, it is contemplated within the scope of the present invention that the housing 10 could be formed in alternate shapes. It is preferred however that the housing 10 be comprised of two operable coupled portions.

Integrally formed with the bottom 13 in the center thereof is mount 20. Mount 20 is formed from a suitable durable material such as but not limited to plastic and is annular in shape having a passage(not illustrated herein) therethrough. Mount 20 extends upward from the bottom 13 and is operable to couple to the blower assembly 50. The mount 50 functions to provide a technique to position and maintain the blower assembly 50 in a vertical upright position without the need for additional structural members within the interior volume of the housing 10. The mount 20 is opposedly formed from the pipe connector 35 that is contiguously formed with the bottom 13. Pipe connector 35 is annular in shape having a hollow passage(not illustrated herein) and extends outward from the bottom 13 and is perpendicular thereto. The pipe connector 35 functions to be mateably coupled to a conventional plumbing pipe utilizing suitable durable techniques. Journaled through mount 20 is fluid aperture 27. Fluid aperture 27 functions to fluidly couple the mount 20 with the interior of the housing 10. As the radon removal apparatus 100 is mounted in outdoor environments the exposure to temperature fluctuations results in the accumulation of condensation within the housing 10. As the condensation accumulates the fluid level will collect on the bottom 13. The fluid aperture 27 facilitates the removal of the collected condensation from the bottom 13 and allows the fluid to egress through the fluid aperture 27 and into a pipe to which the housing 10 has been operably coupled. The removal of the condensation reduces the humidity of the interior volume of the housing 10 and as such provides an improved environment for operation of the blower assembly 50 promoting the longevity of operation of the components thereof. It is contemplated within the scope of the present invention that while only one fluid aperture 27 is illustrated and discussed herein that more than one fluid aperture 27 could be journaled through the mount 20 so as to facilitate the drainage of fluid accumulated at the bottom 13.

The blower assembly 50 is operable to facilitate the flow of radon gas upwards from the bottom 13 towards the exit aperture 75 formed in the upper portion 15 of the housing 10. The blower assembly 50 is mounted in an upright orientation and further includes an impeller 52 and motor 54. The impeller 52 draws radon gas upward from the bottom 13 through mount 20 and expels the radon gas through the exit aperture 75. The upper portion 15 includes wall 16 that is tapered inward so as to direct the flow of gas towards the exit aperture 75 that is integrally formed with the wall 16. In the preferred embodiment of the present invention the impeller 52 is a high pressure vacuum impeller in order to provide the most effective throughput and removal of gas. The impeller 52 is electrically coupled to a motor 54 providing operation thereof. While no particular electric motor is required, in the preferred embodiment of the present invention the motor 54 is a low voltage direct current motor wherein the motor 54 is additionally water resistant.

The blower assembly 50 is secured to mount 20 via coupling 29. Coupling 29 is annular in form having a hollow passage(not illustrated herein) and is operable to provide a technique to couple the impeller 52 to the mount 20. The coupling 29 is manufactured from a vibration reducing material such as but not limited to rubber. Utilizing a material such as rubber provides a mounting technique for the blower assembly 50 that is substantially void of vibrational movement. Reduction of vibrational movement promotes reduced sound production and provides reduced stress on electronic components of the blower assembly 50.

Contiguously formed with the upper portion 15 is the exit aperture 75. The exit aperture 75 includes wall 76 that is angular in orientation to wall 16 and provides a shape that facilitates operable coupling to a conventional pipe or other object if desired. In the preferred embodiment the exit aperture 75 is atmospherically coupled to its immediate environment so as to provide release of the gas thereinto. The exit aperture 75 has formed thereacross a air turbulence diffusion member 80. The air turbulence diffusion member 80 is mounted within the exit aperture 80 so as to extend diametrically across. The air turbulence diffusion member 80 is manufactured from a suitable durable material such as but not limited to plastic. The air turbulence diffusion member 80 is formed as a flat bar and is present at the exit aperture 75 so as to disrupt the cyclonic air flow pattern exiting the housing 10. The formed shape of the upper portion 15 of the housing 10 coupled with the impeller 52 creates an airflow pattern that is circular in shape similar to a tornado or cyclone. This airflow pattern results in the production of significant noise which is undesirable for many applications such as but not limited to residential mounting locations of the radon removal apparatus 100. The shape of the air turbulence diffusion member 80 disrupts the circular air pattern egressing through the exit aperture 75 and as such substantially eliminates the production of noise produced by gas flowing outwards from the exit aperture 75. While the air turbulence diffusion member 80 is illustrated in a form of a flat crossbar herein, it is contemplated within the scope of the present invention that the air turbulence diffusion member 80 could be formed in alternate shapes in order to achieve the desired functionality as described herein.

In the preceding detailed description, reference has been made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments, and certain variants thereof, have been described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that other suitable embodiments may be utilized and that logical changes may be made without departing from the spirit or scope of the invention. The description may omit certain information known to those skilled in the art. The preceding detailed description is, therefore, not intended to be limited to the specific forms set forth herein, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents, as can be reasonably included within the spirit and scope of the appended claims.
