JPH02279942A - Ceiling-embedded cassette type air-conditioner - Google Patents

Abstract

PURPOSE:To secure transmission of a signal by a method wherein infrared rays emitted form a wireless remote control switch are refracted midway and can be made to reach a light-sensing element of the main body of an air- conditioner which is in a positional relationship of being apart therefrom in terms of an angle. CONSTITUTION:A ceiling-embedded cassette type air-conditioner 1 and the main body panel 2 of the air-conditioner are installed in a ceiling part 10, while a wireless remote control switch 6 is fitted on a wall surface 11 by a wall fitting 9 and emits infrared rays. The infrared rays emitted from a light-emitting element 7 in the head of the wireless remote control switch 6 are reflected by a reflecting plate 8 fitted in the vicinity and made to reach a light-sensing element 5 of the main body of the air-conditioner. While the infrared rays can only be emitted in a region indicated by a dotted line (a), even with the directivity reduced as much as possible, when the reflecting plate 8 is not provided, the infrared rays can be made to reach the light-sensing element 5 without fail as indicated by a dotted line (b), with an angle of reflection adjusted to be fit for the light-sensing element 5, by providing the reflecting plate 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a device for transmitting operation signals for an air conditioner, ventilation unit, etc., which is attached to a ceiling surface.

[Conventional technology]

Conventionally, the ceiling-embedded cassette type nitrogen-style dish model 1 was
The air conditioner body was installed anywhere on the large ceiling surface, and a remote control switch with a wire was used to ensure reliable transmission of operation signals.

Furthermore, as shown in FIG. 8, the air conditioner in which the wireless remote control switch is used is a wall-mounted air conditioner 12, etc., and even if the control switch 6 is mounted on the wall for an inch, the light emitting part 7 will emit a signal. The position was such that the information could be transmitted sufficiently.

[Problem to be solved by the invention]

The conventional method described above does not require wiring work and is easy to operate for air conditioners that can be installed anywhere on a large ceiling surface, such as ceiling-embedded cassette type air conditioners. A control switch is required. This remote control switch can be used not only for hand-held operation, but also for operations such as mounting it on a wall and operating the vehicle.Even if the directivity is minimized and infrared signals can be transmitted from a wide range of directions, the relative positional relationship will be affected. Considerable limitations were inevitable, and it was a national challenge to create an air conditioner with highly practical signal transmission. The object of the present invention is to obtain a remote control switch that overcomes these drawbacks.

[Failure to solve the problem]

The above objective was achieved by making the infrared rays emitted from the wireless remote control switch come in contact with oil on the way so that they can reach the light receiving part of the air conditioner body, which is located at an angle of 4n. Ru.

[Effect]

At least one reflector that reflects infrared signal lines is installed near the wireless remote control switch, and the infrared rays emitted from the control switch are reflected so that the angle can be adjusted appropriately with respect to the light receiving part of the air conditioner main body. The light is reflected by the plate and reaches the light receiving section. The angle of this reflector can be adjusted according to the relative position of the air conditioner main light receiving part and the position of the wireless remote control switch, ensuring that infrared rays reach the light receiving part and ensuring signal transmission. can be measured.

〔Example〕

FIG. 1 shows an embodiment of the present invention, in which a ceiling-embedded cassette type air conditioner ■ and an air conditioner body panel 2 are installed on a ceiling 6tf510, and a wireless remote control 6 is attached to a wall surface 11 using a wall mount 9. n. It emits infrared rays, and as shown in detail in FIG.
If there is no reflector plate 8, the infrared rays cannot be emitted in the area shown by the three-dot line even if the directivity is minimized. By providing the reflector plate 8, the reflection angle can be adjusted to match the light receiving section 5, and the infrared rays can be reliably transmitted to the light receiving section 5, as shown by the five-dot line. In addition, for infrared signals, even if the air conditioner main body and the wireless remote controller are provided with a light receiving and emitting part, and the two-way signal reception and transmission capability is provided, this method can reliably transmit and receive signals. .

The fx and anti-g plate 8 may be provided on the head of the wireless remote controller 60 to adjust the reflection angle, or it may be provided on the side of the A4 attachment 9 to adjust the main light reception or light reception of the light in the same way. Depending on the relative positional relationship with the section 5, the angle adjustment function may be made to wait until the transmission and reception of infrared rays are consistent.

〔Effect of the invention〕

According to the invention, the wireless remote control does not involve operating the wireless remote control switch by hand-holding it and directing it toward the light receiving or receiving/emitting part of the air conditioner or receiving signals from the nitrogen conditioner. This has the effect that the switch is mounted on the wall and can reliably transmit and receive infrared signals to and from the ceiling-embedded cassette-type conditioner installed on the ceiling at a considerable angle away.
