[0001]

[Industrial applications]

 The present invention relates to a ceiling fan that can be remotely controlled.

[0002]

[Prior Art]

 In recent years, there has been a demand for a ceiling fan that has a wide-range reception function without blind spots and can be operated remotely from an unspecified location.

Conventionally, this type of ceiling fan has a configuration as shown in FIG. As shown in the figure, an outer rotor type motor 102 is built in the ceiling fan main body 101, and a fixed shaft 103 is press-fitted and fixed to a stator 102a of the motor 102. The main body 101 is hung on the ceiling surface at the upper end of the fixed shaft 103, and a control box 104 containing electrical components is mounted at the lower end of the fixed shaft 103. The upper surface and side surfaces of the motor 102 are covered with a motor cover 105, and the blades 106 are radially attached to the lower surface of the rotor 102b of the motor 102.

A ring-shaped light guide 107 is wound around a side peripheral surface of a motor cover 105 that covers the motor 102. A plurality of receivers 108 are arranged inside the light guide 107 and are connected in the control box 104.

An illuminator 109 is attached to the upper portion of the motor 102, and an illuminator cover 110 is provided on the upper portion thereof.

In the above structure, when an optical signal is transmitted from the remote control device 111, at least one of the receivers 108 receives the optical signal via the light guide 107 and processes the signal in the control box 104. Then, the operation of the motor 102 is controlled.

[0007]

In such a conventional ceiling fan, when an illumination lamp 112 such as a fluorescent lamp is installed on the ceiling near the front of the receiver 107, the light from the ceiling-attached illumination lamp 112 is There is a problem that the optical signal from the remote control device 111 becomes relatively stronger, and the optical signal cannot be detected by the receiver 108, so that the remote control cannot be performed.

Further, in order to maintain the receiving sensitivity of the receiver 108, another component for blocking the light from the ceiling-mounted illuminating lamp 112 is required, which increases the number of components and the number of mounting steps. Had challenges.

The present invention solves the above problem. Even when the ceiling-mounted illuminator 110 is present near the front of the receiver 108, the receiver 108 is not affected by the light of the illuminator 110. A first object is to be able to receive an optical signal from a remote control device.

A second object is to realize a structure in which the receiver 108 is not affected by light from the ceiling-mounted illuminating lamp 112, simply and at low cost.

[0011]

[Means for Solving the Problems]

 A first means for achieving the first object of the present invention is to attach a motor cover surrounding a motor, a plurality of blades radially arranged on a lower surface of the motor, and a side surface of the motor cover. It has a light guide, a receiver for receiving an optical signal through the light guide, and a remote control device for transmitting an optical signal to the light guide, and is inclined to surround the side of the light guide. It is configured to have an eaves portion.

A second means for achieving the second object is, in addition to the configuration of the first means, an illuminator attached to the upper part of the motor cover and a visor for covering the upper part of the illuminator. The illuminator cover has an eaves illuminator cover, and the illuminator cover with an eave is configured such that a peripheral edge portion is extended to integrally form an inclined eaves portion that surrounds a lateral side of the light guide.

[0013]

With the configuration of the first means described above, according to the present invention, by surrounding the side of the light guide on the side periphery of the motor cover with the sloping eaves, the ceiling near the front of the receiver is provided. Even if an illumination light is installed, the light from this illumination light is blocked by the eaves, and the optical signal from the remote control device is transmitted to the receiver without interruption.

Further, according to the configuration of the second means, by extending the peripheral edge portion of the illuminator cover and integrally forming the eaves portion surrounding the side of the light guide, the number of parts and the number of mounting steps are increased. It is possible to block the light from the illumination lamp installed on the ceiling without any effort.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. The same components as those of the conventional example are denoted by the same reference numerals and detailed description thereof will be omitted.

As shown in the figure, an annular light guide 107 is wound around the side peripheral surface of a motor cover 105 that covers the motor 102. A plurality of receivers 108 are arranged inside the light guide body 107 and are connected to the control box 104. The eaves portion 1 surrounding the side of the light guide body 107 is provided so as to be inclined.

In the above structure, the optical signal transmitted from the remote control device 111 is introduced into the inside of the light guide body 107 from the lower opening of the eaves portion 1 directly or by being reflected to the inside of the eaves portion 1. An optical signal is transmitted to the receiver 108 while traveling inside the body 107 while being internally reflected. The optical signal received by the receiver 108 is processed in the control box 104 to control the operation of the motor 102. When there is an illuminating lamp 112 such as a fluorescent lamp on the ceiling near the front of the light guide body 107, light with stronger energy than the optical signal transmitted from the remote control device 111 is often emitted. Since the eaves portion 1 is provided on the side of the body 107, it is possible to block the light from the illumination lamp 112.

As described above, according to the ceiling fan of the first embodiment of the present invention, since the eaves portion 1 surrounding the side of the light guide body 107 is provided in an inclined manner, the remote control device 111 coming from below is provided. It is possible to collect the optical signal transmitted from the light guide body 107 and to introduce it into the light guide body 107, and to block the strong light of the illumination lamp 112 attached to the ceiling near the front of the receiver 108, and thus the receiver. Reference numeral 108 can accurately receive the optical signal from the remote control device without being affected by the light of the illumination lamp 112.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same components as those of the conventional example and the first embodiment of the present invention are designated by the same reference numerals and detailed description thereof will be omitted.

As shown in the figure, the illuminator 108 attached to the upper part of the motor cover 105 is covered with the illuminator cover 2 with an eaves shown in FIG. 3 instead of the illuminator cover 110 shown in FIG. The illuminator cover 2 with an eaves is formed by integrally forming the illuminator cover 110 and the eaves portion 1. That is, the eaves portion 1 corresponds to the extended peripheral edge portion of the illuminator cover 2 with an eaves, and surrounds the light guide body 107 in a laterally inclined state.

In the above-mentioned configuration, since the illuminator cover 2 with the eaves provided on the motor cover 105 has the extended peripheral end portion as the eaves portion 1 for the light guide 107, it is possible to illuminate the vicinity of the ceiling fan. Even when the device 108 is mounted, the light from the illuminator 108 can be prevented from entering the light guide 107, and the optical signal from the remote control device 111 can be reliably received.

As described above, according to the ceiling fan of the second embodiment of the present invention, by providing the illuminator cover 2 with the eaves with the illuminator cover 110 and the eaves portion 1 integrated, the eaves portion 1 is formed. It is possible to obtain the same light shielding effect as in the case where it is provided, and since it is not necessary to add the eaves portion 1 separately, it is possible to reduce the number of parts and the number of mounting steps.

[0023]

[Effect of the device]

 As is apparent from the above-described embodiments, according to the present invention, the strong light of the illumination lamp attached to the ceiling is blocked by providing the eaves which are inclined so as to surround the side of the light guide, and the remote control is performed. Since the optical signal from the operating device can be reflected by the eaves and received, even if an illuminator such as a fluorescent lamp is attached to the ceiling near the ceiling fan, the ceiling fan can be accurately operated remotely. Can be provided.

Further, by integrating the eaves portion with the illuminator cover, it is possible to provide a ceiling fan that can reduce the number of parts and the number of mounting steps as compared with the case where the eaves portion is added as a separate component.
