Description

Description: TECHNICAL FIELD The present invention relates to a transmitted light transmission device and a transmitted light transmission method of a remote control mechanism, and more particularly, to an air conditioner fixed to a wall surface, a wall-mounted television, and the like. The present invention relates to a transmission light transmission device and a transmission light transmission method of a remote control mechanism for remotely controlling a controlled device by a cordless controller.

<Prior Art> As shown in FIG. 6, a conventional remote control mechanism includes an air conditioner 51 (controlled device) fixed to a wall surface 50.
The air conditioner 51 is provided with a light receiving section 51a provided in front of the air conditioner 51 and a cordless controller 52 for transmitting the transmitted light to the light receiving section 51a to remotely control the air conditioner 51. Then, the transmission light emitted from the light emitting portion 52a of the cordless controller 52 controls ON / OFF of the air conditioner 51.

By the way, the cordless controller 52 is originally the air conditioner 51.
The first purpose is to allow the controlled device such as the above to be operated from a distant place, and to be used by being placed at the operator's hand. However, when the air conditioner 51 is used for business in an office, a factory, etc., it is necessary to determine the installation position of the cordless controller 52 and make it convenient for an unspecified number of people to use.

Therefore, conventionally, by arranging the cordless controller 52 detachably below the air conditioner 51 on the wall surface 50, the setting position is specified, and when necessary, the cordless controller 52 is removed from the wall surface 50 to remotely control the air conditioner 51. Was there.

<Problems to be Solved by the Invention> However, in the above-described conventional structure, the light receiving unit 51a has the air conditioner 51a.
Since the cordless controller 52 is provided only on the front side of the wall, when the transmitted light is emitted while the cordless controller 52 is arranged on the wall surface 50, the cordless controller 52 does not reach the light receiving section 51a. Therefore, the cordless controller 52 is temporarily attached to the wall surface 50.
From the wall 50 after the control of the air conditioner 51 is completed.
The cordless controller 52 had to be returned to, and the control of the air conditioner 51 was extremely troublesome.

In order to solve such a problem, JP-A-1-150735
In the gazette, as shown in FIG. 7, a light receiving portion 51b is provided on the lower surface of the air conditioner 51 so that the transmitted light transmitted to the lower surface of the air conditioner 51 can be received. It is disclosed.

However, in order to provide the two light receiving parts 51b in the air conditioner 51, it is necessary to drastically change the design of the air conditioner 51, which is not only difficult to implement but also the cost of the product becomes high.

The present invention has been made in view of the above problems, by causing the operator operating the cordless controller to reflect the transmitted light and indirectly transmit the transmitted light to the light receiving unit, any design change to the controlled device can be made. An object of the present invention is to provide an improved transmission optical transmission device and transmission optical transmission method of a remote control mechanism that can be easily implemented at a low cost without adding.

<Means for Solving the Problems> In order to solve the above problems, a transmission light transmission device of a remote control mechanism according to the present invention includes a controlled device fixed to a wall surface and a light receiving portion provided in front of the controlled device. And a cordless controller for remotely controlling the controlled device by transmitting transmitted light to the light receiving section,
In a transmitted light transmission device of a remote control mechanism in which the cordless controller is removably arranged below the controlled device on the wall surface, the transmitted light is indirectly reflected by an operator who operates the cordless controller. In addition, an indirect transmission mechanism for transmitting to the light receiving section is provided.

Further, according to the transmission light transmission method of the remote control mechanism in the present invention, the light is transmitted from the cordless controller detachably arranged below the controlled device on the wall surface to the light receiving portion in front of the controlled device fixed to the wall surface. In a transmitted light transmitting method of a remote control mechanism that emits light to perform remote control, the transmitted light is indirectly transmitted to the light receiving unit by being reflected by an operator who operates the cordless controller.

<Operation> The transmitted light emitted from the cordless controller is reflected by the operator and indirectly transmitted to the light receiving portion provided on the front surface of the controlled device.

<Example> Hereinafter, an example will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic side view showing a use state of the first embodiment,
An air conditioner 2 as a known controlled device is fixed to the wall surface 1 itself. A light receiving unit 2a is provided on the front of the air conditioner.

Light emitting unit 4a that emits infrared rays with a wavelength of about 940 nm using LEDs
Are arranged.

As shown in FIG. 2, the mounting member 3 includes a substantially rectangular substrate portion 5. A pair of screw holes 6 facing each other in the vertical direction are formed in the board portion 5, and the mounting member 3 is fixed to the wall surface 1 by a screw (not shown) passing through the screw holes 6.

Support arms 7 and 8 facing each other are integrally provided from both side edges of the substrate portion 5. The support arms 7 and 8 are
These are for hugging the cordless controller 4 (FIG. 1) together with the base plate 5 and the bottom plate 9 that integrally extends from the lower edge of the base plate 5 and curves so as to approach each other toward the tip end side.

A reflection plate 10 as an indirect transmission mechanism integrally extends from the upper edge of the substrate portion 5. The reflecting plate 10 has a convex spherical surface on the side facing the light emitting portion 4a (FIG. 1) of the cordless controller 4, and the upper end side is inclined in a direction away from the wall surface 1 when viewed from the side. The inclination angle θ of the reflecting plate 10 is set to, for example, 25 °, and the angle at which the transmitted light reflected by the reflecting plate 10 hits the head 12 of the operator 11 who operates the cordless controller 4 (FIG. 1) as described later. Is set to. It is to be noted that the shape of the inclined plate 10 is most preferably the convex spherical shape described in FIG. 2 in order to diverge the transmitted light so as to correspond to the operators 11 of different heights.
Alternatively, the flat plate-shaped inclined plate 10 shown in FIG. 3 may be employed.

According to the above-mentioned structure, as shown in FIG. 1, the operator can mount the cordless controller 4 on the mounting bracket 10.
