Bladeless fans with a nozzle

Abstract

A bladeless fan is provided. In one embodiment, a bladeless fan is provided having a base, a support rod extending from the base, and a fan arm movably coupled to the support rod. The base, the support rod, and the fan arm can include a first adjustment point configured to allow the fan arm to be positioned in a first horizontal orientation and a second vertical orientation, a second adjustment point configured to allow adjustment of a radial position of the fan arm around a longitudinal axis of the support rod, and at least one additional adjustment point configured to allow at least one of rotational adjustment of at least a portion of the fan arm about a longitudinal axis of the fan arm and adjustment of a distance between the base and the fan arm.

What is claimed is: 
     
         1 . A bladeless fan, comprising:
 a base configured to be positioned on a surface, a portion of the base being rotatable relative to the surface;   a support rod coupled to the base; and   a fan arm rotatably coupled to the support rod at a connection joint, the fan arm having first and second fan arm portions rotatably coupled to opposite sides of the connection joint,   wherein first and second airflow openings are formed in the first and second arm portions, respectively, and   wherein rotation of an impeller within the base is configured to generate airflow that is emitted from the fan arm.   
     
     
         2 . The bladeless fan of  claim 1 , wherein the portion of the base is configured to rotate about a first axis perpendicular to the surface. 
     
     
         3 . The bladeless fan of  claim 2 , wherein the fan arm is configured to rotate about a second axis perpendicular to the first axis and parallel to the surface. 
     
     
         4 . The bladeless fan of  claim 3 , wherein the first and second fan arm portions are configured to rotate about a third axis different than the first and second axes. 
     
     
         5 . The bladeless fan of  claim 4 , wherein, in a first fan orientation, the fan arm is parallel to the support rod and the third axis is parallel to the first axis and perpendicular to the second axis, and wherein, in a second fan orientation, the fan arm is perpendicular to the support rod and the third axis is perpendicular to the first axis and parallel to the second axis. 
     
     
         6 . The bladeless fan of  claim 1 , wherein the support rod is coupled to the base such that the support rod is configured to rotate together with the portion of the base. 
     
     
         7 . The bladeless fan of  claim 1 , wherein the support rod is movably coupled to the base such that the support rod is configured to rotate independently of the portion of the base. 
     
     
         8 . The bladeless fan of  claim 1 , wherein the support rod is configured to be tilted such that the support rod extends outwardly from the base at an acute angle relative to a central axis of the base. 
     
     
         9 . The bladeless fan of  claim 1 , wherein a distance between the connection joint and the base is adjustable. 
     
     
         10 . The bladeless fan of  claim 1 , wherein the first and second fan arm portions are independently moveable. 
     
     
         11 . The bladeless fan of  claim 1 , wherein at least one of movement of the base, movement of the support rod, movement of the fan arm, movement of the connection joint, and movement of the first and second fan arm portions is a motorized movement. 
     
     
         12 . The bladeless fan of  claim 11 , wherein the bladeless fan is in wireless communication with a user device, and wherein the motorized movement is configured to be remotely controlled via the user device. 
     
     
         13 . The bladeless fan of  claim 1 , wherein the first and second airflow openings are configured to emit air in different directions from each other. 
     
     
         14 . The bladeless fan of  claim 1 , wherein the generated airflow flows from the base into an airway of the support rod, through an airway of the connection joint, through an airway of the fan arm, and through the first and second airflow openings to be emitted from a plurality of nozzles. 
     
     
         15 . A bladeless fan, comprising:
 a base, a support rod extending from the base, and a fan arm movably coupled to the support rod, wherein the base, the support rod, and the fan arm include a first adjustment point configured to allow the fan arm to be positioned in a first horizontal orientation and a second vertical orientation, a second adjustment point configured to allow adjustment of a radial position of the fan arm around a longitudinal axis of the support rod, and at least one additional adjustment point configured to allow at least one of rotational adjustment of at least a portion of the fan arm about a longitudinal axis of the fan arm and adjustment of a distance between the base and the fan arm.   
     
     
         16 . The bladeless fan of  claim 15 , wherein the at least one additional adjustment point comprises a third adjustment point configured to allow rotational adjustment of at least a portion of the fan arm about a longitudinal axis of the fan arm, and a fourth adjustment point configured to allow adjustment of a distance between the base and the fan arm. 
     
     
         17 . The bladeless fan of  claim 16 , wherein the first adjustment point comprises a pivot joint formed between the fan arm and the support rod. 
     
     
         18 . The bladeless fan of  claim 17 , wherein the second adjustment point comprises a rotational joint formed on at least one of the base and the support rod. 
     
     
         19 . The bladeless fan of  claim 18 , wherein the third adjustment point comprises at least one rotational joint formed on the fan arm. 
     
     
         20 . The bladeless fan of  claim 19 , wherein the fourth adjustment point comprises a sliding joint formed between the fan arm and the support rod.
