Abstract
Description
- Ventilating exhaust fans, such as those typically installed in bathrooms, draw air from within an area and pass the exhausted air out to another location, such as through a vent in the gable or roof of a home or other building structure. Centrifugal exhaust fans typically include a rotating fan wheel having a plurality of vanes that create an outward airflow which, in turn, is directed out of an outlet opening. The fan wheel is typically coupled to a motor supported within the fan housing, and the motor drives the fan wheel, thus providing ventilation to an area. In some cases, a curved fan scroll is employed to channel air around the fan, and can be defined by a housing wall of the fan or by a separate element or structure within the fan housing.
- Many typical exhaust fans currently in use include a housing positioned within a building structure, such as in an aperture in a wall or ceiling. The housing can be secured in the aperture in a number of conventional manners, such as by being attached to wall or ceiling joists, or by being attached to other structure in the wall or ceiling.
- In some cases, it may be desirable to replace an exhaust fan within a building or structure. For example, an old exhaust fan may need to be replaced when broken, or may generate unacceptable vibration or noise during operation. As another example, it may be desirable to replace an old exhaust fan with one that is more powerful, or has one or more features or characteristics different than the existing exhaust fan. However, conventional exhaust fans can be relatively difficult and time consuming to remove and replace.

For example, as shown in the side-rear view of aupgrade cartridge assembly 20 inFIG. 6a andFIG. 6b , the scroll features agrille spring holder 110 according to one embodiment of the invention. Referring to the exploded projection view inFIG. 15 , in some embodiments, thegrille spring holder 110 can be used with aspring 115 to conveniently secure agrille 117 to theventilation assembly 10. -
FIG. 7 is a top perspective view of aventilation assembly 10 according to one embodiment of the invention. As discussed earlier, one or more of the embodiments of theupgrade cartridge assembly 20 as shown inFIG. 1-5 may be coupled with amain housing 25 to form aventilation assembly 10. For example, inFIG. 7 , theventilation assembly 10 is shown in perspective without theaforementioned grille 117, (shown inFIG. 15 ). A bottom perspective view is shown inFIG. 8 , showing the bottom side of themain housing 25. In some embodiments, themain housing 25 may be formed into any shape, included but limited to, a rectangular box-like shape, an oval shape, a hemispherical shape, a spherical shape, a pyramidal shape, or any other shape. In some embodiments the main housing is formed from a sheet metal, including, but not limited to an aluminum-based metal, a steel or iron-based metal, a zinc-based metal, or a nickel and tin-based metal. In some other embodiments, themain housing 25 may be formed from injection molded polymers, thermo-formed polymers, thermosetting polymers, or sheet metal, or any other suitable material. In some other embodiments, the housing may comprises a wood-based product, such as wood, or particle-board or wood laminate. In some embodiments, themain housing 25 can form a base or a similar support structure of theventilation assembly 10. Furthermore, in some embodiments, themain housing 25 can provide points and areas of attachment for theupgrade cartridge assembly 20, or other components of theassembly 10. - In some embodiments, the
ventilation assembly 10 can include aduct connector assembly 270, comprising afirst end 274 coupled with themain housing 25, and the blower outlet 55 (not shown), and asecond end 276, forming aventilation orifice 272. In some embodiments, theduct connector assembly 270 is pre-installed in a building structure and the duct connector assembly is coupled with a ventilation duct of a building with thesecond end 276 of theduct connector assembly 270. In some embodiments, themain housing 25 is firstly installed in an existing cavity or aperture of a structure such as a wall or ceiling. Subsequently theduct connector assembly 270 is installed by connecting asecond end 276 with a ventilation duct of a building, and afirst end 274 with an aperture in the main housing 25 (not shown). Installation is completed by securing aupgrade cartridge assembly 20 substantially in the main housing, positioning theblower outlet 55 adjacent to thefirst end 274 of theduct connector assembly 270 installed adjacent to an aperture of themain housing 25. - Moreover, as shown in
FIG. 7 , illustrating a top perspective view of aventilation assembly 10 according to one embodiment of the invention, the duct connector assembly can comprise adamper flap 280. In some embodiments, theventilation assembly 10 can be operable to discharge fluid flow from a space to another location. For example, in some embodiments, when power is provided to theupgrade cartridge assembly 20, amotor 30, such as a permanentsplit capacitor motor 30, can rotate ablower wheel 50 positioned substantially within ascroll 40. Fluid flow is moved substantially towards the duct assembly, and themoveable damper flap 280 coupled with aventilation orifice 272 will open, allowing fluid to be expelled from theventilation assembly 10. In some embodiments thedamper flap 280 can control the backflow of a fluid into theventilation orifice 272 and theupgrade cartridge assembly 20, and further be capable of substantially controlling the flow of fluid from a space, such as a room, into the ventilation duct of a building, or structure, to an outside location. - As discussed previously, some embodiments of the invention comprise a cartridge upgrade assembly that includes a motor mounting plate. For example, as shown in

In some embodiments, thescroll 40 includes at least onescrew boss 90 which provides an anchoring feature for afastener 73 to secure thescroll 40 to themotor mounting plate 70. As shown inFIG. 9 , a permanentsplit capacitor motor 30 is mounted on the opposite side of themotor mounting plate 70, and thesecond end 62 of the main drive bolt can be seen at the base of themotor 30. - As described previously, it may be desirable to replace an exhaust fan within a building or structure. For example, an old exhaust fan may need to be replaced when broken, if the fan produces excessive vibration or noise during operation. It may be desirable to replace an old exhaust fan with one that is more powerful, or has one or more features or characteristics different than the existing exhaust fan. However, conventional exhaust fans can be relatively difficult and time consuming to remove and replace. By providing a
ventilation assembly 10 that comprises aupgrade cartridge assembly 20 with certain attachment and detachment features, replacement or upgrade can be a faster and less complex task. For example, as discussed earlier, some embodiments of the invention include ascroll 40 with a fan cartridge snap retention feature 85 (seeFIG. 2 andFIG. 5 ). In some embodiments of the invention, aupgrade cartridge assembly 20 is secured into amain housing 25 using at least one fan cartridgesnap retention feature 85. For example referring toFIG. 10 showing a side perspective view of aventilation assembly 10 according to one embodiment of the invention, the fan cartridgesnap retention feature 85 can be seen engaged into an aperture in themain housing 25. In some embodiments of the invention, one or more fan cartridgesnap retention feature 85 can retain theupgrade cartridge assembly 20 in amain housing 25 without the use of additional tools or hardware.
