Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device that remotely controls an air conditioner mainly using optical signals (hereinafter referred to as wireless type).

2. Description of the Related Art Conventionally, it has been known to perform wireless remote control using optical signals such as infrared rays to operate televisions and the like. As shown in Fig. 1, a common means for this is to operate a light emitting element attached to a remote control part a to emit an optical signal toward a light receiving element d attached to a main body C of a television or the like. .

However, in the case of something that requires frequent operation, such as a television, the operation device is kept at hand and the transmission is directed toward the television, allowing for accurate reception. However, in the case of an air conditioner, as shown in Figure 2, The remote control unit e is mainly attached to the wall, and it can be operated only once, so frequent operations are not required.

Therefore, in the conventional wireless remote control device, when the remote control unit e is attached to the wall f as shown in Fig. 2, the light emitting element g has directivity, so that light is directly applied to the light receiving element. This is difficult, and the light must be delivered to the light-receiving element by reflection from the ceiling, floor, or wall.

However, in this case, the loss until reception is large, the propagation of light is unstable, and the air conditioner main body i, in which the light emitted from the light emitting element reaches the light receiving element, may not operate.

The present invention solves the above-mentioned drawbacks of the conventional remote control device, and includes a reflector plate attached to the front surface of the light emitting element of the remote control unit, and the light emitted from the light emitting element is reflected by the reflector plate to control the air conditioner. This ensures that light is delivered to the light receiving element in the main body.

Hereinafter, the present invention will be described with reference to FIGS. 3 to 6 of the accompanying drawings showing embodiments thereof.

Now, one embodiment will be explained with reference to FIGS. 3 and 4.

In the figure, 1 is a remote control unit, and 2 is this remote control unit 1.
3 is a light-emitting element provided in the air conditioner main body, 4 is a light-receiving element provided in the air conditioner main body 3, and 5 is a reflection plate provided on the front surface of the light-emitting element 2 on the side of the remote control unit 1. be. This reflecting plate 6 reflects the light emitted from the light emitting element 2 and regulates the light so that it directly reaches the light receiving element 4.

Next, the structure of the reflecting plate 6 will be explained with reference to FIG.

In the figure, the reflector 6 is a flat reflector 5! The L and the mounting end from part 6a, and the plane reflection part 5a is mounted to part 6b so that the angle can be changed forward, backward, left, and right as shown by the arrows in the same figure, so that the light emitted from the light emitting element is It can be adjusted to ensure that the light reaches the light receiving element. Furthermore, the mounting section 6b can be mounted to either the remote control section 1 or a wall surface by adhesive means.

The structure in which the optical signal from the remote control unit 1 reaches the light receiving element 6 and is processed within the air conditioner main body 3 and the operation of this process are basically the same as the structure used in televisions. , and is not related to the gist of the present invention, so a description thereof will be omitted.

In the above configuration, the air conditioner main body 3 is attached to a desired position on the wall surface of the room, and the remote control unit 1 is similarly attached to a desired position on the wall surface. The installation of this remote control unit 1 has traditionally been limited to locations that do not interfere with daily life and do not damage the interior of the room, but as described in the conventional example, it is possible to successfully receive optical signals. It may not be possible. Therefore, by adjusting the reflector 6, the light emitting element 2
This ensures that the optical signal reaches the light receiving element 4.

Therefore, the air conditioner body 3 can be placed in the position desired by the user.
Even if the remote control unit 1 is attached and the reception of the optical signal is uncertain, the light from the light emitting element 2 can be reliably guided to the light receiving element 4 by adjusting the reflector plate 5. Air conditioning can be operated.

In addition, in this embodiment, the reflecting part 51 of the reflecting plate 6 is
is a flat plate such as a mirror, but as shown in FIGS. 5 and 6, a convex spherical part 6c is provided on the reflecting part 6a to diffusely reflect the light from the light emitting element 2 and guide the optical signal to the light receiving element 4. In this case, even if the remote control section 1 is installed in a position with more complicated conditions, reliable reception of the optical signal can be expected. In addition to rotation, a structure that expands and contracts in the vertical direction as shown by the broken line arrows in FIGS. 4 and 6 may be added. Furthermore, the attachment part 6b is not limited to the remote control part 1 Since it can be attached to an indoor wall or the like as appropriate, the remote control unit 1 can also be operated by hand in the same way as when using a telephoto.

As is clear from the above embodiments, the remote control device for an air conditioner according to the present invention includes a light emitting element provided in the remote control section of the air conditioner capable of wireless remote control. A reflector is attached to send light to the light-receiving element on the main body of the machine.When the remote control unit is mounted on a wall, the reflector ensures that the light reaches the light-receiving element, and the air conditioner The main body can be made to perform the operations as instructed. Furthermore, by rotatably attaching the reflector to the remote control unit, it is possible to refract the straight-progressing light in any direction, thereby making it possible to receive light more reliably. Furthermore, by diffusely reflecting the light from the light-receiving element using a reflector plate, the directivity of the optical signal can be made over a wide range, so the optical signal can be reliably transmitted to the air conditioner body even if it is indoors or has a complex shape. It has various advantages, such as the ability to
