DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling fan suspended from a ceiling by a support member,
More specifically, the present invention relates to a ceiling fan having a control board mounted therein.

[0002]

2. Description of the Related Art In general, a ceiling fan is provided with a control board as a control section for controlling the operation of a motor for driving a blade, such as starting, stopping, and adjusting the number of revolutions, and a control section for an attached lighting fixture. Is built-in. Conventional ceiling fan vane is formed of a predominantly iron plate, The motor also not a lightweight, such as an inverter motor, hanger inevitably weight becomes heavy, suspending the ceiling fan body for induction motor strength It is made by die casting so that it can withstand.

Therefore, the control board cannot be directly mounted on the die-cast hanger, and the control board holder is mounted on the hanger attached to the upper portion of the motor shaft of the support member made of a pipe, which also serves as the stator shaft of the motor. The control board is attached to this holder.

[0004]

As described above, the control board cannot be directly mounted on the hanger made of die cast.
The structure was complicated because the control board holder was attached to the hanger and the control board was attached to this holder.
Further, depending on the arrangement of the control board, it is not possible to reduce the size of the ceiling fan in the vertical direction by bringing the blades of the ceiling fan closer to the ceiling.

The present invention has been made in order to solve such a problem, and the present invention has been made to directly control a hanger for hanging a lightweight main body of a ceiling fan without other members such as a mounting bracket. By installing a board holder and attaching a control board to this holder, it is possible to reduce the number of parts and simplify the structure, or devise the mounting of the control board so that the position of the ceiling fan blades is closer to the ceiling, An object of the present invention is to provide a ceiling fan in which the size of the fan in the vertical direction is reduced.

[0006]

In order to achieve the above object, a ceiling fan according to claim 1 of the present invention comprises a simple mounting bracket attached to a ceiling in a canopy (upper cover) and a hanger formed of resin. Along with a rotating body with blades at the lower end of the support shaft which is suspended by engagement and also serves as a motor shaft,
At the lower end of the hanger and above the motor, a control board holder made of resin is provided integrally with the hanger in a direction perpendicular to the axis of the support shaft, and a control board is attached to the control board holder. And

As described above, since the ceiling fan main body is lightened by reducing the weight of the motor and the blades, the strength is sufficient even if the hanger is formed of resin, and since the hanger is formed of resin, the board mounting holder is also integrated with the hanger. And an insulating effect can be expected. As a result, other members such as a mounting bracket become unnecessary, which contributes to cost reduction and simplifies the surroundings of the control board.

The ceiling fan according to claim 2 of the present invention is suspended by engaging a simple mounting bracket attached to the ceiling in the canopy (upper cover) with a resin-formed hanger,
A rotor with a blade is provided at the lower end of the support shaft also serving as a motor shaft, and a control board holder formed integrally with the canopy is provided inside the canopy, and a control board is attached to the control board holder, The ceiling is covered with a lid, and the lid is attached to a simple mounting bracket.

Further, the position of the blades of the ceiling fan can be made closer to the ceiling to reduce the size of the ceiling fan in the vertical direction, and the space between the ceiling and the motor is only the thickness space of the simple mounting bracket. The degree of freedom of the position and the position of the blade is increased. Further, the heat of the motor unit is not easily transmitted to the control board, and the reliability of the electronic component can be improved.
