Description
- The present invention relates to a fan with oscillating mechanism, and more particularly to an oscillating fan that can be wirelessly controlled with a portable mobile device to operate in different manners.
- An electric fan usually includes a fan blade assembly having blades with a curved configuration each. The fan blade assembly is driven by a driving motor to rotate, so that air is sucked into the fan from one side of the blades and then blown out of the fan from the other side of the blades to thereby produce airflow toward a target object. However, the blades can only produce linearly moved airflow. To direct the linearly moved airflow produced by the fan to different directions, an oscillating mechanism must be additionally provided for the fan.
- According to the oscillating mechanisms thereof, the currently available fans can be generally divided into two types, namely, a cover-rotating fan and an oscillating fan.
- The cover-rotating fan includes an air guiding mechanism arranged at a front side of the overall fan structure. The air guiding mechanism normally includes a plurality of parallelly spaced tilted slats. When the air guiding mechanism is rotated, the originally linearly moved airflow produced by the fan meets the rotating tilted slats and is automatically directed to different flowing directions to thereby produce a widened breezy area.
- The oscillating fan is a fan provided in a base thereof with a rotary mechanism for producing an oscillating motion of the fan. That is, the rotary mechanism reciprocatingly rotates a main shaft of the fan to thereby change the direction of the produced airflow. When the oscillating fan operates, the whole fan oscillates about the rotary mechanism to swing to and fro sidewardly within a large span.
- Both the cover-rotating fan and the oscillating fan use a motor as their power source. To regulate the fan motor's rotational speed, a user has to manipulate a control switch or turn a control knob on the fan to change an input impedance of the fan, so as to change the electric current input to the fan motor and accordingly, increase or decrease the volume and speed of air flow output from the fan.
- The conventionally designed fan control structure allows the user to change the air volume and speed of the fan by manipulating the control switch or turning the control knob. However, it is possible the fan is positioned on a relatively high place or mounted on a ceiling and the control switch or the control knob is out of the user's reach. In this case, a pull-cord switch hung from the fan or a wired control unit at a remote location from the fan is usually provided for the user to control the fan. However, the pull-cord switch and the wired remote control unit might not allow the user to conveniently and quickly control the fan when the fan is mounted on some special position for some particular purpose. Therefore, it is desirable to provide a further improved control system for an overall control of a fan.
- A primary object of the present invention is to provide a control system for fan with concealed oscillating mechanism, which includes a fan internally provided with an oscillating mechanism and a portable mobile device wirelessly linkable to the fan for controlling the operation of the oscillating mechanism, so that a user may directly use the fan via the wireless linking function of the portable mobile device even if the fan is mounted on a place that could not be easily accessed. As a result, the fan has largely increased practicality and usability.
- Another object of the present invention is to provide a fan with concealed oscillating mechanism, so that a fan blade assembly of the fan can be driven by driving motors of the fan to rotate in 360-degree directions and accordingly blow air to all directions. Meanwhile, components of the driving motors and the oscillating mechanism of the fan are uniformly loaded to enable stable and smooth operation of the fan, minimize the condition of stress fatigue in the oscillating mechanism, upgrade the fan's air delivery efficiency, and avoid damage of the fan.
- To achieve the above and other objects, the control system for fan with concealed oscillating mechanism according to the present invention includes an oscillating fan and a portable mobile device. The oscillating fan has 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 portable mobile device is provided on a surface with a touch panel, which forms an operation control interface, and is internally provided with a processor having a control module and a transmission unit wirelessly linkable to the receiving control unit. The processor is electrically connected to the touch panel and the transmission unit. 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. The transmission unit and the receiving control unit can link to each other via a wireless communication protocol, such as Bluetooth, Wi-Fi or WIMAX.
- The control module of the processor selectively enables the operation control interface to show an actuation icon before actuation or an operation page after actuation. 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.
- 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.
- In a preferred embodiment of the present invention, the oscillating mechanism includes a pivoting member, a second driving motor, and a crank connecting member. The pivoting member is 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 is pivotally connected to an inner side of the hollow pivoting frame. The second driving motor is connected to a rear end of the first driving motor and has 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. The crank connecting member is 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.
- 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. The connecting member on the housing member is 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.
- The oscillating fan further includes a hood structure 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. And, a heater can be additionally provided in the oscillating space and electrically connected to the receiving control unit.
- The present invention is characterized in that the oscillating fan includes the receiving control unit that is wirelessly linkable to any type of portable mobile device. When a user operates on the touch-type operation control interface of the portable mobile device, a control command is generated by the portable mobile device for driving the oscillating fan to blow air or to oscillate while blowing air. In this manner, the user can still conveniently control and use the fan even if the fan is mounted on a place that could not be easily accessed, such as a higher position or a corner. Therefore, the fan can have largely increased practicality and usability.
