System, apparatus, and method for providing a flow of air
An apparatus is disclosed. The apparatus has a first housing having a first cavity, a second housing disposed in the first housing and including a second cavity and at least one aperture, a first fan assembly configured to generate a first airflow through the first housing, and a second fan assembly configured to generate a second airflow from the second cavity to the first cavity via the at least one aperture.
1. An apparatus, comprising:
a first housing having a first cavity;
a second housing disposed in the first housing and including a second cavity and at least one aperture, wherein the second housing includes a base assembly and a cover assembly that is rotatably attached to the base assembly;
a first fan assembly disposed in the first housing, wherein the first fan assembly is configured to generate a first airflow through the first housing;
a second fan assembly disposed in the second cavity of the second housing, wherein the second fan assembly is configured to generate a second airflow from the second cavity to the first cavity via the at least one aperture;
a first motor positioned between the first fan assembly and an inner side of the second fan assembly; and
a second motor positioned such that either the first fan assembly or the second fan assembly is located between the first motor and the second motor.
2. The apparatus of claim 1 , further comprising a controller integrated into the first housing, wherein the controller is configured to adjust at least one of a speed of the second fan assembly and the at least one aperture in the second housing.
3. The apparatus of claim 1 , wherein the second fan assembly includes a second fan having a second diameter.
4. The apparatus of claim 3 , wherein the first fan assembly includes a first fan having a first diameter that is greater than a diameter of the second housing.
5. The apparatus of claim 1 , wherein the first fan assembly includes a first fan driven by a first shaft and the second fan assembly includes a second fan driven by a second shaft, the first shaft and the second shaft being concentric shafts.
6. The apparatus of claim 1 , wherein the first housing is one of a table fan housing supported by a stand or a ceiling fan housing supporting the second fan assembly that is a ceiling fan assembly.
7. The apparatus of claim 1 , wherein a first step portion forming a first recess that faces away from the second cavity is disposed in the at least one aperture.
8. The apparatus of claim 7 , wherein a second step portion forming a second recess that faces toward the second cavity is disposed in the at least one aperture.
9. The apparatus of claim 1 , wherein the at least one aperture includes a plurality of apertures formed by at least a first portion of each of a plurality of base apertures of the base assembly being respectively aligned with at least a second portion of each of a plurality of cover apertures of the cover assembly.
