This application claims the benefit of U.S. Provisional Patent Application No. 62/636,186, filed Feb. 28, 2018, the entire contents of which are hereby incorporated by reference herein.
BACKGROUNDThe present disclosure relates to fans and, in particular, to modular fans.
Fans are typically positioned within rooms to circulate air within that room. Some fans include blades or impellers positioned within a housing such that the blades or impellers are not visible to a user. These fans are commonly referred to as bladeless fans. A bladeless fan typically draws air through an opening in the housing and guides the air through inner pathways until the air is pushed out of airways in a desired direction. Taking advantage of the Bernoulli principle and Coanda effect, the geometry uses high velocity air expelled from the airways to draw additional surrounding air into the airflow zone, increasing a total air flow.
SUMMARYIn one embodiment, a modular fan assembly may include a fan unit and a mount assembly removably connected to the fan unit. The fan unit may include a fan housing, an impeller disposed within the fan housing, a motor coupled to the impeller to drive the impeller, and first electrical contacts disposed on the fan housing. The first electrical contacts can electrically communicate with the motor. The mount assembly may include a support housing removably connected to at least a portion of the fan housing and second electrical contacts disposed on the support housing. The second electrical contacts can electrically communicate with the first electrical contacts.
In another embodiment, a method of assembling a modular fan assembly may include providing a fan unit. The fan unit may include a fan housing, an impeller disposed within the fan housing, a motor coupled to the impeller to drive the impeller, and fan electrical contacts disposed on the fan housing. The method may also include providing a first mount assembly. The first mount assembly may include a first support housing removably connectable to at least a portion of the fan housing and first mount electrical contacts positioned to electrically couple to the fan electrical contacts. The method may further include providing a second mount assembly. The second mount assembly may include a second support housing removably connectable to at least a portion of the fan housing and second mount electrical contacts positioned to electrically couple to the fan electrical contacts. The method may also include selectively coupling the fan unit to the first mount assembly or the second mount assembly.
In another embodiment, a modular fan system may include a fan unit, a first mount assembly removably connectable to the fan unit, and a second mount assembly removably connectable to the fan unit.

With reference to
The fan unit 110 may include a motor 116, a fan housing 118, and an impeller 120. The impeller 120 may be disposed within the fan housing 118 and be coupled to an output shaft of the motor 116. The output shaft may extend along (e.g., parallel to) an impeller rotation axis A1 of the fan unit 110. The motor 116 may also be disposed within the fan housing 118. The motor 116 may drive (e.g., rotate) the impeller 120 by way of the output shaft causing the impeller 120 to rotate about the rotation axis A1 and induce an airflow. In some embodiments, the nozzle 126, the motor 116, and/or the impeller 120 may be co-axial respective to the impeller rotation axis A1 and/or concentric.
The fan housing 118 may include an air inlet 122 and a nozzle 126 in fluid communication with the air inlet 122. The nozzle 126, as shown in the illustrated embodiment, may be an annular nozzle. Other embodiments may include a nozzle 126 that may be square, rectangular, oblong, elliptical, oval, hexagonal, octagonal, and/or the like. In some embodiments, the nozzle 126 may be positioned about the motor 116 and the impeller 120. Air may be drawn into the annular nozzle 126 by way of rotating the impeller 120, drawing the air in through the air inlet 122, and forcing the air into the nozzle 126 from which the air may ultimately be expelled. In the illustrated embodiment, the air inlet 122 may be comprised of a series of air vents 130 (see e.g.,
The fan unit 110 may additionally include electrical contacts 134 (see e.g.,
With continued reference to
In the illustrated embodiment, the mount assembly 114 may include a base member 150, an elongated support member 154, and a support housing 158. The base member 150 may be a wall or ceiling mount, and the elongated support member 154 may be a wall or ceiling mount arm. The base member 150 may be configured to be mounted to a wall or a ceiling of a room via fasteners 162 (e.g., screws, nails, bolts, etc.). The elongated support member 154 may be connected to the base member 150 and may include a bifurcated end 166 that movably supports the support housing 158. In some embodiments, the elongated support member 154 may be a swivel arm that allows the fan unit 110 to be positioned in various positions. The support housing 158 may be pivotally connected to the bifurcated end 166 of the elongated support member 154 to allow the support housing 158 to rotate relative to the elongated support member 154 about a pivot axis A2. The pivot axis A2 may be perpendicular to the impeller rotation axis A1.
With reference to
As shown in
During operation of the modular fan assembly 100, electrical current or power may be provided by a power source and be routed to the motor 116 by way of routing the power through the electrical wiring 174 and the electrical contacts 134, 178. The motor 116 may rotate the impeller 120 to draw air from outside the fan unit 110 through the air vents 130 of the air support housing 158 and the air inlet 122 and into the fan housing 118. The impeller 120 may continue to push the air through the arms 146 and into the annular nozzle 126. Air pressure may begin to build within the annular nozzle 126 as more air is pushed into the annular nozzle 126. Once the air pressure is high enough, the air may be continually expelled from the annular outlet 142 and away from the fan unit 110. Due to the high air pressure, the air may be expelled at a high velocity, drawing air surrounding the fan unit 110 through the central opening 138 and creating an amplified airflow effect.
As discussed above, the fan unit 110 may be removably connected to a mount assembly 114, 210, 310. The fan unit 110 may be removed from one mount assembly 114, 210, 310 and connected to another mount assembly 114, 210, 310 with or without the use of one or more tools. For example, the fan unit 110 may be removed from the mount assembly 114 with the base member 150 and positioned into the mount assembly 210 with the elongated stem 222 or the mount assembly 310 with the shorter stem 318. The fan unit 110 may be pivotable and/or rotatable respective to the respective mount assembly by way of pivoting and/or moving about a pivot axis (e.g., A2) and/or moving about a universal joint.
A fan unit 110 that is removably connected to a mount assembly 114, 210, 310 allows for the easy repositioning of the fan unit 110 within a room. The convenience of a removable fan unit 110 allows for the fan unit 110 to provide airflow in a variety of ways within a room, and/or allows the fan unit 110 to be moved from room to room.
