Abstract

PROBLEM TO BE SOLVED: To capture an optical signal coming from the horizontal direction, by a condensing cover, and surely perform the remote control by detecting the same by a light receiving sensor, by installing one light receiving sensor on a lower part of a ceiling electric fan body, and covering a front face thereof with a convex condensing cover which transmits the light. SOLUTION: An optical signal sent from a remote control device toward a condensing cover 16 mounted on a lower edge of a main body 1, is collected on a central part by a convex condensing cover 16. The optical signal is converted into an electric signal by a light receiving sensor 13, to operate and control a motor 3. The light condensing cover 16 is located on the lowermost end part of the center of the main body 1, and is made of a transparent or translucent synthetic resin. Further a surface is hemispherically projected, so that even the optical signal from the horizontal direction, can be transmitted through the light condensing cover 16 to be guided to the light receiving sensor 13. Accordingly, the optical signal can be surely received from the remote control device without increasing a number of light receiving sensors 13.

【Example】

(Embodiment 1) As shown in FIG. 1, a main body 1 of a ceiling fan is covered with a main body cover 2 on the outside, and an outer-rotor type motor is provided.
A hollow shaft 4 penetrates the center of a stator (not shown) of the motor 3. The main body 1 is attached to a mounting bracket 6 via a joint 5 fixed to the upper end of the shaft 4.
, And the mounting bracket 6 is covered with a metal cover 8. The rotor 9 of the motor 3 has a plurality of blades 10 attached thereto.

The motor 3 is remotely controlled by an optical signal. A support 12 is fixed to the lower end of the shaft 4, and a light receiving unit 11 is mounted on the support 12.
The light receiving unit 11 comprises a sensor case 15 to which the light receiving sensor 13 and the light receiving connector 14 are fixed, and a light collecting cover frame 17 in which a convex light collecting cover 16 is fitted in the center. The screw 13 is screwed to the support 12 so that 13 faces downward. By fitting the light collecting cover frame 17 to the support 12, the light collecting cover 16 is arranged on the front surface of the light receiving sensor 13.

A main board 18 and a circuit board 19 are fixed in the main body 1, and a main body cover-2 is fitted around the main body. The circuit board 19 incorporates a triac 20, a relay 21 and the like, and is connected to the light receiving connector 14 via a connector 24 by a light receiving lead wire 25. A capacitor 22, a transformer 23, and the like are arranged on the main body board 18, and a power supply lead line 27 is
Is connected to a power supply via a hooking seal 28 fixed to the ceiling surface 7.

In the above configuration, the optical signal transmitted from the remote control device (not shown) to the light collecting cover 16 provided at the lower end of the main body 1 is collected at the center by the light collecting cover 16 having a convex shape. The light signal is converted by the light receiving sensor 13 into an electric signal, and the signal is processed in the control circuit of the circuit board 19 via the light receiving lead line 25 to control the operation of the motor 3. At this time, the light collecting cover 16 is located at the lowermost end of the center of the main body 1, is formed of a transparent or translucent synthetic resin, and has a surface protruding in a hemispherical shape. However, the optical signal can be guided to the light receiving sensor 13 through the light collecting cover 16 and the optical signal from the remote controller can be reliably received without increasing the number of the light receiving sensors 13. .

The lamp unit 33 protrudes from the bracket 32 in four directions. Further, the light receiving unit 11 is provided in the center of the inside of the bracket 32. That is, the light receiving sensor 13 is held by the sensor case 15, and the front surface thereof is covered by the light collecting cover 16. The direction of light emission of the light unit 33 is outward with respect to the bracket 32, and the light collecting unit 16 provided at the center of the bracket 32 has
Light from the light is difficult to enter. A relay lead 34 is connected between the light receiving connector 14 and the light receiving lead 25.

In the above configuration, when the light receiving unit 11 receives an optical signal transmitted from a remote control device (not shown), the electric lamp unit 33 is provided on the bracket 32 because the electric lamp unit 33 is directed outward with the bracket 32 as a center. The influence of the illumination light of the electric lamp unit 33 on the light receiving unit 11 is small, and it is possible to reach the condenser cover 16 without disturbing the waveform of the optical signal.

In the above configuration, when a large number of main bodies are mounted on a high ceiling such as a gymnasium and in a large area, when a floor surface is used, even if an optical signal is transmitted from a distant place, attenuation occurs. And spread, making remote control difficult. In such a case, remote control can be easily performed by attaching the light receiving sensor 13 separated from the main body 1 to a place where an optical signal can easily reach such as a wall. The removed light-collecting cover 16 may be attached to the main body 1 again.

Also, in a restaurant or the like, where the ceiling surface is low and the guest seats are partitioned by a block near the ceiling for each block, and it is difficult for an optical signal to reach from a distance, or a waiting corner for a customer service staff. Even when the user wants to perform control while watching the situation from-, the operability can be improved by separately installing the light receiving sensor 13 in an operable place.

As is apparent from the above embodiments, according to the present invention, one light receiving sensor is provided at the lower portion of the ceiling fan main body, and its front surface is covered with a convex light-collecting cover that transmits light. Therefore, an optical signal traveling from the lateral direction is also captured by the light-collecting cover, and the ceiling fan can be provided which has an effect of being detected by the light-receiving sensor and being reliably operated remotely.

Also, a lighting fixture is attached to the lower part of the main body,
A light receiving sensor is provided downward at the center of the lighting fixture, and an electric lamp part is arranged radially from the center of the lighting fixture, and the front surface of the light receiving sensor is covered with a light-collecting cover. It is possible to provide a ceiling fan having an effect that remote operation can be reliably performed without any trouble.
