Control system for fan with concealed oscillating mechanism

Abstract

A fan control system includes an oscillating fan and a portable mobile device. The oscillating fan includes a housing member having a first driving motor arranged therein, and an oscillating mechanism mounted between the first driving motor and the housing member to electrically connect to the first driving motor and a receiving control unit. The portable mobile device has a touch panel forming an operation control interface, and is internally provided with a processor electrically connected to the touch panel and a transmission unit. The operation control interface produces an operation control signal when being touched, and the processor receives the operation control signal and correspondingly generates a control command to the transmission unit, from where the control command is wirelessly transmitted to the receiving control unit in the oscillating fan. The oscillating fan directly controllable via the portable mobile device has largely increased practicality and usability.

What is claimed is: 
     
         1 . A control system for fan with concealed oscillating mechanism, comprising:
 an oscillating fan having a housing member, a first driving motor arranged in the housing member, an oscillating mechanism mounted between the first driving motor and the housing, a fan blade assembly assembled to a first rotary shaft of the first driving motor to locate in front of the first driving motor, and a receiving control unit electrically connected to the oscillating mechanism and the first driving motor, the oscillating mechanism includes a pivoting member, a second driving motor, and a crank connecting member; the pivoting member being configured as a hollow pivoting frame, which is pivotally connected at an outer side to an inner side of the housing member, and the first driving motor being pivotally connected to an inner side of the hollow pivoting frame; the second driving motor being connected to a rear end of the first driving motor and having a second rotary shaft extended in a direction parallel to the first rotary shaft, so that the second rotary shaft is eccentric relative to the first rotary shaft; and the crank connecting member being connected at a first end to the second rotary shaft of the second driving motor and at an opposite second end to a connecting member provided in the housing member; and   a portable mobile device being provided on a surface with a touch panel, which forms an operation control interface, and being internally provided with a processor having a control module and a transmission unit wirelessly linkable to the receiving control unit; and the processor being electrically connected to the touch panel and the transmission unit; and   wherein the operation control interface produces an operation control signal when being touched by a user, and the processor receives the operation control signal and correspondingly generates a control command to the transmission unit, from where the control command is wirelessly transmitted to the receiving control unit in the oscillating fan.   
     
     
         2 . The control system for fan with concealed oscillating mechanism as claimed in  claim 1 , wherein the transmission unit and the receiving control unit are linked to each other via a wireless communication protocol selected from the group consisting of Bluetooth, Wi-Fi and WIMAX. 
     
     
         3 . The control system for fan with concealed oscillating mechanism as claimed in  claim 1 , wherein the control module selectively enables the operation control interface to show one of an actuation icon before actuation and an operation page after actuation. 
     
     
         4 . The control system for fan with concealed oscillating mechanism as claimed in  claim 3 , wherein, on the operation page, there are shown at least an air speed regulation switch for driving the first driving motor to operate and an oscillation control switch for driving the oscillating mechanism to operate and oscillate. 
     
     
         5 . The control system for fan with concealed oscillating mechanism as claimed in  claim 4 , wherein the operation page further has a time switch shown thereon for turning on or off the first driving motor and the second driving motor, and the receiving control unit in the oscillating fan is correspondingly provided with a timer module for coordinately working with the time switch. 
     
     
         6 . The control system for fan with concealed oscillating mechanism as claimed in  claim 1 , wherein the crank connecting member is provided at the first end thereof with a shaft hole, in which the second rotary shaft is fitted, and on the second end with a ball-shaped supporting head; and the connecting member on the housing member being configured as a socket corresponding to the ball-shaped supporting head, such that the engaged ball-shaped supporting head and socket functions like a ball-and-socket bearing. 
     
     
         7 . The control system for fan with concealed oscillating mechanism as claimed in  claim 1 , wherein the oscillating fan further includes a hood structure, the hood structure being fixedly fitted around an outer periphery of the housing member and internally defining a forward protruded oscillating space, in which a front portion of the housing member and the fan blade assembly are located. 
     
     
         8 . The control system for fan with concealed oscillating mechanism as claimed in  claim 7 , further comprising a heater provided in the oscillating space, and the heater being electrically connected to the receiving control unit.
