## Title
Retrofittable grill fan assembly

## Abstract

A retrofittable grill fan assembly for PURPOSE includes a housing that has a first end wall, a second end wall and a perimeter wall attached to and extending between the first and second end walls. An air conduit is attached to the housing and is in fluid communication with an interior of the housing. The air conduit extends outwardly and downwardly from the housing. A coupler is mounted on the housing and is releasably engaged to an upper edge of a grill bowl. A fan is positioned within the housing and the housing at least one air inlet extending therethrough. The fan draws air into the housing through the at least one air inlet and expels air outwardly through the conduit when the fan is turned on. A power supply is electrically coupled to the fan and an actuator is electrically coupled to the fan to turn the fan on or off.

## Background
BACKGROUND OF THE DISCLOSURE
Field of the Disclosure
The disclosure relates to grill fan devices and more particularly pertains to a new grill fan device for positioning on a grill to feed oxygen to the grill.
SUMMARY OF THE DISCLOSURE
An embodiment of the disclosure meets the needs presented above by generally comprising a housing that has a first end wall, a second end wall and a perimeter wall attached to and extending between the first and second end walls. An air conduit is attached to the housing and is in fluid communication with an interior of the housing. The air conduit extends outwardly and downwardly from the housing. A coupler is mounted on the housing and is configured to releasably engage an upper edge of a grill bowl. A fan is positioned within the housing and the housing at least one air inlet extending therethrough. The fan draws air into the housing through the at least one air inlet and expels air outwardly through the conduit when the fan is turned on. A power supply is electrically coupled to the fan and an actuator is electrically coupled to the fan to turn the fan on or off.

There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new grill fan device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the retrofittable grill fan assembly 10 generally comprises a housing 12 having a first end wall 14, a second end wall 16 and a perimeter wall 18 attached to and extending between the first 14 and second 16 end walls. The perimeter wall 18 includes a front wall 20. The housing 12 may have a length from the first end wall 14 to the second end wall 16 less than at least 50.0 cm and more particularly less than 35.0 cm.
An air conduit 22 is attached to the front wall 20 of the housing 12 and is in fluid communication with an interior of the housing 12. The air conduit 22 extends outwardly and downwardly from the housing 12. More particularly, the air conduit 22 including a first section 24 attached to the housing 12 and a second section 26 is distal to the housing 12. The first section 24 extends horizontally away from the housing 12 a distance equal to at least 2.0 cm. The second section 26 is angled downwardly from a horizontal plane between 20° and 90°. The second section 26 may be arcuate to match the contour of a grill 60.
A coupler 28 is mounted on the housing 12. The coupler 28 is configured to releasably engage an upper edge 64 of a grill bowl 62. The coupler 28 includes a pair of catches 30 attached to the front wall 20 and placed such that the air conduit is positioned between the catches 30. The catches 30 may include L-shaped clips.
A fan 32 is positioned within the housing 12. The housing 12 has at least one air inlet 34 extending therethrough. The fan 32 draws air into the housing 12 through the at least one air inlet 34 and expels air outwardly through the conduit 22 when the fan 32 is turned on. The fan 32 more particularly includes a motor 34 and a propeller 36 or impeller. A cage fan is shown in the Figures though any conventional fan apparatus may be utilized. A power supply 38 is electrically coupled to the fan 32. The power supply 38 may comprise a rechargeable battery. A charging port 40 is mounted on the housing 12 and is electrically coupled to the battery to facilitate recharging of the battery. The charging port 40 may be used for electrically coupling the power supply 38 with a conventional power source such as with a male wall outlet plug 42 or may be powered, for instance, with a vehicle electric source with a male power port plug 44. An actuator 46 is electrically coupled to the fan 32 to turn the fan 32 on or off and may further be used for selecting a fan speed.
In use, the housing 12 is placed on the bowl 62 of the grill 60. The bowl 62 is generically defined as the vessel used to hold coals or other fuel used for cooking. The fan 32 is turned on, as needed, to blow air into the bowl 62 to feed additional oxygen to the coals.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
