Description

The present invention relates to an air conditioner equipped with a cordless remote control device.

(Prior Art) For example, a light receiving portion of a cordless type remote control device used in an air conditioner such as an air purifier or an air conditioner for heating and cooling is provided only on the front surface of the main body of the air conditioner. Is generally used (see, for example, JP-A-60-42541).

(Problems to be solved by the invention) However, as described above, in the case where the light receiving portion of the transmitted light at the time of cordless transmission is provided only and is attached only to the front surface portion of the air conditioner main body, Only the area corresponding to the above-mentioned light receiving part in front of the air conditioner body can be operated, which means that the operator is resident at a specific position in the room such as a factory or a work place, and cannot move freely. If the installation location is under such environmental conditions and there is a small area for installation on the wall surface side as well, the installation form of the air conditioner body itself will be greatly saved.

Therefore, for example, light receiving portions are provided on both the front surface and the lower surface of the air conditioner body, and the transmitted light from the light emitting portion of the remote controller is cordlessly fed from the front area of the air conditioner body. It is conceivable that each of the air conditioners can be configured to be able to receive light from the lower region of the air conditioner in a fiber coded state.

However, when such two types of signal transmission modes are adopted, generally, the transmission efficiency (attenuation rate) of light is not the same in the air and the optical fiber. For example, infrared light has a low attenuation rate in the air and a high transmission efficiency, but on the other hand, in an optical fiber made of synthetic resin, on the contrary, the attenuation rate increases and the transmission efficiency decreases.

Further, for example, red visible light having a wavelength longer than the infrared light has a high attenuation rate in the air and a low signal transmission efficiency, but the attenuation rate in the optical fiber made of the synthetic resin is low, and the signal transmission efficiency is low. high.

Therefore, the reliability of the above configuration cannot be improved without considering these circumstances.

(Means for Solving Problems) The present invention has been made for the purpose of solving the above problems, and in order to solve the problems, for example, as shown in FIGS. In addition, a wall-mounted air conditioner main body 1 attached to the wall surface 5, an optical transmission type handheld remote controller 6 including a light emitting unit for remotely controlling the air conditioner main body 1, and the air conditioner main body 1 The first light receiving portion 41 provided on the front surface portion 9, the second light receiving portion 42 provided on the lower surface portion 10 of the air conditioner body 1, the upper end side to the second light receiving portion 42, and the lower end portion. And an optical fiber 30 detachably connected to the light emitting portion of the handheld remote controller 6 via connector portions 38 and 31, respectively, and transmits light transmitted from the light emitting portion of the handheld remote controller 6 to the optical fiber. The cordless state without the bar 30 can be received from the front side region of the air conditioner body 1, and the fiber cord state can be received from the lower side region of the air conditioner body 1 via the optical fiber 30. In the air conditioner configured as described above, in the first and second light receiving units 41, 42, the front side first light receiving unit 41 is an infrared light receiving unit, and the lower side second light receiving unit.
Reference numeral 42 denotes a light receiving portion for red visible light, each having a different light receiving wavelength, and correspondingly, the light emitting portion on the side of the handheld remote controller 6 is also the infrared light emitting portion 21 and the red visible light emitting portion. It is configured to have two kinds of light emitting portions having different emission wavelengths from each other.

(Operation) According to the problem solving means of the present invention, in the case where the wall-mounted air conditioner main body 1 is remotely controlled by the optical transmission type handheld cordless remote controller 6 including the light emitting unit as described above, Light receiving portions on the side of the air conditioner body 1 are provided at two locations on the front surface side and the lower surface side of the air conditioner body 1. Therefore, the air conditioner can be controlled not only from the front side transmission area of the air conditioner main body 1 but also from the lower side transmission area, and the transmission area is greatly expanded.

Moreover, in that case, the control from the front side transmission area is in a cordless state, and the control from the lower side transmission area is provided through the optical fiber 30 which has connectors 38 and 31 at both upper and lower ends and is detachably connected. The remote controller 6 can be detachably locked and attached to the lower end of the optical fiber 30 via the connector 31 even when there is no suitable place to fix the remote controller 6 on the wall surface side. .

If the optical fiber 30 is removed and the remote controller 6 is attached to the wall surface side, the same control can be performed in a cordless state.

Corresponding to the difference in the two signal transmission modes, the front side first light receiving section 41 on the side of the air conditioner body 1 is an infrared light receiving section having a high signal transmission efficiency in the air, and the lower surface thereof. The second side light-receiving unit 42 is configured as a light-receiving unit for red visible light having a high signal transmission efficiency in the optical fiber, each having a different light-receiving wavelength, and the hand-held remote controller 6 side also corresponds to them. There are provided light emitting units 21 and 22 having different emission wavelengths for infrared light and red visible light. Therefore, it is possible to secure high signal transmission efficiency corresponding to the respective signal transmission modes of light, and it is possible to reliably and accurately transmit signals.

(Embodiment) FIG. 1 to FIG. 9 show a configuration of an air conditioner according to an embodiment of the present invention.

First, FIG. 1 shows an overall system configuration of an air conditioner in the embodiment. In the figure, reference numeral 1 denotes an air conditioner main body such as an electric dust collector type air cleaner. . The air conditioner main body 1 is centered on an electric dust collecting element configured to have a dust collecting cell, and the dust collecting cell surrounds a high pressure generating portion of an ion generating portion (corona discharge electrode) and the high pressure generating portion. It is composed of a dust collecting electrode plate, and each of the parts is connected to the external housing 11
It is built in. Then, the air taken in through the grill portion 12 provided on the front surface side of the outer casing 11 is guided to the above-mentioned electric dust collecting element through a pre-filter (not shown), and first, the ion generating portion in the electric dust collecting element. Then, the dust particles in the air are charged, and the charged dust particles are electrostatically adsorbed by the dust collecting electrode plate to collect the dust.

Further, the air conditioner body 1 in the present embodiment is, for example, as shown in FIGS. 2 (a) to 2 (e), [1] wall-mounted type (FIG. 2a), [2] stand type. (Fig. 2b ... Installed on the floor via the stand 90), [3] Ceiling suspension type (Second
C), [4] Ceiling-embedded type (Fig. 2d), and [5] Pon-mounting type (Fig. 2e). As a wall-hanging type corresponding structure of a), as shown in the same figure, engaging holes for engaging with hook-shaped hooks 2, 2 fixed to the wall surface 5 side are provided on the left and right of the rear side upper end portion of the outer casing 11. Hanging flange with 3,3 4,
4 is installed. And the air conditioner body 1
Is hung on the wall surface side hook-shaped hooks 2 and 2 via the flanges 4 and 4, so that the wall surface portion 5 having a predetermined height in the room.
It is installed in the position, and therefore, in the installed state, by pulling the lower surface portion 10 side forward, it is possible to rotate by a predetermined angle to the state of the imaginary line shown in FIG. 2 (a). , Will be described in detail later).

On the other hand, reference numeral 6 is a hand-held remote controller for controlling the operating state of the air conditioner body 1 (for example, turning the power on / off, adjusting the fan strength H / L). In the remote controller 6, for example, as shown in detail by disassembling each part in FIG. 3, a transmission control circuit board 62 having a hybrid structure is housed and fixed via a keyboard plate 64 in a box-shaped main body side remote control box 61. A remote control cap (lid member 63) having a battery storage section described later is fitted from the upper side. The transmission control circuit board 62 has a front end side 62A.
And a first light emitting portion 21 and a second light emitting portion 22 which are located on the rear end side 62B and have different emission wavelengths from each other, and which are, for example, LEDs.
Are provided respectively. Then, the transmission control circuit of the transmission control circuit board 62 is projected from the keyboard slate 64 side to the front side operation panel surface 61a through the operation button through holes 65a, 65b, 65c, 65d of the remote control box 61. A keyboard circuit that operates in response to the operation of some operation buttons 25a, 25b, 25c, 25d provided and outputs operation information, and encodes the information content according to the operation information from the keyboard circuit. A pulse encoder circuit for outputting, a pulse generating circuit for generating a pulse signal of a predetermined reference oscillation frequency different from the light source frequency of ambient light, and a pulse signal from the pulse generating circuit for the above-mentioned operation by the encode signal of the pulse encoder circuit. A burst circuit of the mixing circuit, which is composed of a mixing circuit for converting into a burst signal encoded according to information and outputting the burst signal. Optionally allowed to emit each corresponding said first or second light emitting portions 21 and 22 in accordance with the signal output. Here, the first light emitting portion 21 is an infrared light emitting portion having a wavelength of about 940 nm using, for example, a potassium / arsenic infrared LED, and the second light emitting portion 22.
Are each formed in a red visible light emitting portion having a wavelength of about 60 nm using, for example, a gallium / phosphorus red LED. It is known that the signal transmission efficiencies of the first and second light emitting units 21 and 22 differ greatly depending on their transmission modes.
For example, in the case of the first light emitting unit 21 using a gallium / arsenic red LED, the gallium / phosphorus red LED is generally used.
The luminous efficiency is high and the attenuation rate in the air medium is lower than that of the second light emitting section 22 using the. Therefore, it is suitable for signal transmission in a cordless state. On the other hand, however, as is clear from the graph of FIG. 4, if a transmission mode through a relatively inexpensive synthetic resin optical fiber such as a plastic fiber is adopted, there is a disadvantage that the attenuation rate becomes large on the contrary.
This is because the absorption / scattering loss in the material of the optical fiber that determines the transmission loss in the optical fiber, the radiation loss due to the bending of the optical fiber, the cladding loss, etc. are the characteristics of the optical fiber used and the wavelength of the transmission light. The red visible light having a longer wavelength than that of the first light emitting section 21 using the infrared light is based on the fact that the degree of dependence on the wavelength is large when the material is specified. It is shown that the second light-emitting unit 22 using is more suitable for signal transmission using an optical fiber.

The remote control box 61 of the remote controller 6
The side of the first light emitting portion 21 of the inside is exposed to a transparent window 26 made of acrylic, and infrared rays of the above-mentioned wavelength are transmitted through the transparent window 26 in the optical axis direction of the first light emitting portion 21. It is designed to emit light rays in a fiberless state. Further, the second light emitting portion 22 is fitted in the center portion of the light emitting portion holder whose center is extended and fixed in the width direction of the remote control box 61 from above and below to be securely fixed. For locking the first optical fiber connector 31 attached to the one end (end portion on the light emitting portion side) 30a side of the optical fiber 30 described later, which is located on both sides of the bottom space inside the box and faces the front position. First fitting grooves 32, 32 are provided in which the flange piece 34 is fitted in a sliding state from the upper side. The remote control cap 63, which is fitted and integrated with the remote control box 61 from the back side, is cut out in a concave shape from the portion corresponding to the fitting grooves 32, 32 of the remote control box 61 to the first optical fiber described later. Connector
31 mating spaces 460 are formed.

As shown in FIG. 5, the first optical fiber connector 31 has a connector body 33 and a connector body 33 that are detachably fitted and fixed to the light emitting portion side end 30a of an acrylic optical fiber 30, for example. The first fitting groove on the remote control box body side integrally formed integrally with the front side of the remote control box
32, 32 and a locking flange piece 34 that fits into the 32. The connector main body 33 has an optical fiber insertion hole 34a having a circular cross section that penetrates in the central portion axial direction.
A slit 36 for fitting the ring-shaped stopper 35 is formed, the stopper 35 is fitted into the slit 36 from above, and the slice surface 37a is inserted into the optical fiber insertion hole 34a and the flange 37 The connector body 33 is fixed to the light emitting unit side end 30a of the optical fiber 30 in a state of being aligned with the outer surface of the piece 34. On the other hand, when the stopper 35 is removed, the fixed state between the optical fiber 30 and the connector body 33 is released.

Therefore, when the first optical fiber connector 31 is fitted and fixed in the first fitting grooves 32, 32 on the remote control box 61 side by using the locking flange piece 34, The slice surface 37a is connected to the second light emitting portion 22.
The red visible light from the second light emitting section 22 is introduced into the optical fiber 30. On the other hand, a second optical fiber connector 38 having the same structure is attached to the other end side 30b of the optical fiber 30 as in the case of the one end side 30a described above. Then, the light guided from the second light emitting section 22 into the optical fiber 30 via the first optical fiber connector 31 is guided to the second optical fiber connector 38 through the optical fiber 30. Further, in FIG. 5, reference numeral 39 is a connector body of the second optical fiber connector 38,
Reference numeral 40 denotes the locking flange piece.

The remote control cap 63 shown in FIG. 3 has a recess 63a for accommodating the battery, and the battery lid 81 can be detachably attached when the batteries 80, 80 are accommodated in the recess 63a for accommodating the battery. It is supposed to be combined.

On the other hand, a first light emitting portion 41 corresponding to the first light emitting portion 21 of the remote controller 6 is provided on the front surface portion 9 of the outer housing 11 of the air conditioner main body 1, and a first light emitting portion 41 is provided on the lower surface portion 10. A second light emitting section 42 corresponding to each of the two light emitting sections 22 is provided, and each of these light receiving sections 41, 42 is composed of a photodiode whose sensitivity is set corresponding to the wavelength of each of the above light emitting sections 21, 22. Each is connected to the input side of the corresponding receiving side control circuit. The control circuit includes, for example, a decoder that decodes the coded transmission signal into an original operation information signal, and the decoded operation information signal corresponds to the operation information, for example, a transistor relay type air conditioner main body. It is configured to supply to the side power supply switch circuit or the air volume switching switch circuit of the fan motor drive control circuit (excitation current control circuit) unit.

First, the first light receiving portion 41 is installed close to the right side portion of the lower end of the front surface portion 9 of the outer casing 11 of the air conditioner body 1, and specifically, as shown in FIG. An optical filter 44, a waveguide space 45, a first light receiving element 46 such as a photodiode, and a reflecting surface 47 formed on the right side wall surface of the waveguide space 45 in FIG. 6 are provided.

Further, a remote control accommodating recess 51 for accommodating the above-mentioned remote controller 6 in the rear direction is formed on the left side of FIG. 6 of the first light receiving section 41. The remote control receiving recess 51 is provided adjacent to the first light emitting unit 41 as shown in the figure, while the remote controller 6 is provided.
In the state in which is housed, the front side operation panel surface 61a is configured to have a depth such that the surface 61a coincides with the wall surface of the front surface portion 9 of the air conditioner body 1 and forms a substantially flush plane as a whole. In the state, one of the first and second light emitting portions 21 and 22 of the remote controller 6 faces the reflecting surface 47 through the waveguide space 45 of the first light receiving portion 41. There is. This is shown, for example, in FIGS.
As shown in comparison with FIG. (B), the air conditioner body 1 is arranged upside down, and the remote controller 6 is displayed according to the display (characters such as operation: ON / stop: OFF) on the operation panel 61a.
Even when the left and right sides of the first light emitting unit 21 and the second light emitting unit 22 are housed with their left and right sides reversed, the light emitting unit and the reflecting surface 47 are changed only by reversing the positional relationship between the first light emitting unit 21 and the second light emitting unit 22. The facing relationship is surely maintained, and the character display is always in the upright state.

The optical filter 44 of the first light receiving unit 41 is a frequency filter that transmits only the light from the first light emitting unit 21 and cuts the light of the frequency from other unnecessary light sources (light sources that become disturbance light). The infrared light from the first light emitting portion 21 of the remote controller 6 which is always used in a cordless state is transmitted and the first light receiving is performed through a part of the waveguide space 45. Lead to element 46. The waveguide space 45 is formed between the optical filter 44 and the first light receiving element 46, and communicates with the remote control accommodating recess 51. Therefore, when the remote controller 6 is accommodated in the remote control accommodating recess 51 as described above, the light from the first light emitting portion 21 or the second light emitting portion 22 of the remote controller 6 is transmitted to the waveguide space. The light is guided to the first light receiving element 46 and the reflecting surface 47 via 45. The light guided to the reflecting surface 47 is of course reflected by the reflecting surface 47 and enters the light receiving element 46 at the same time as the direct incident light, thereby increasing the amount of light incident on the first light receiving element 46. Therefore, even if the waveguide space 45 is formed in parallel with the light receiving surface from the lateral direction, it may be combined with the reflected light on the back surface of the optical filter 44, so that a sufficient amount of incident light can be secured, which is reliable. It is possible to secure high operating performance and reliability.

In this case, in view of the structure and function described above, the optical filter 44 is directly attached to the surface of the first light receiving element 46, and the light receiving window surface portion on the outer surface side of the housing 11 is made of acrylic or the like. It is of course possible to install a transparent plate or the like to form the waveguide space 45 similar to the above.

However, in that case, when the second light emitting unit 22 that employs red visible light is selected as the light emitting unit facing the reflecting surface 47, the frequency of the light emitting unit is different, so that it is necessary to devise a band setting. .

Next, the second light receiving portion 42 of the lower surface portion 10 of the air conditioner body 1
Is, for example, as shown in FIG. 8, a second light receiving element 56 formed of a photodiode as described above and the second light receiving element 56.
On the light receiving surface 56a of the optical fiber 30
And a fitting portion of the second optical fiber connector 38 for connecting and fixing the slice surface 37b of 0b in a state of being opposed to each other, and the fitting portion is provided with the second optical fiber connector 38. With the fitting grooves 57, 57 into which the flange pieces 40 are slidably fitted from both sides on the back surface side and the second optical fiber connector 38 are removed, the air conditioner body 1 is straightened from below the rear surface. To the above photo detector
The light receiving surface 56a of 56 is provided with an introducing space portion 48 for introducing the red visible light from the second light emitting portion 22 of the handheld type remote controller 6 by completely removing the optical fiber 30.

Therefore, the second light receiving element 56 of the second light emitting section 42 and the second light emitting section 22 of the remote controller 6 remove the optical fiber 30 and transmit the control signal in a cordless state as described above. The first remote control system and the second remote control system, which is directly connected through the optical fiber 30 and transmits the control signal, are connected by two kinds of remote control systems. In addition, in addition to the above-mentioned direct control system, there are finally three types of control systems in total, and by attaching or detaching the optical fiber 30 to or from any one of them, the remote controller 6 Can be freely and freely selected by attaching / detaching to / from the air conditioner body 1. It has been cut way. Moreover, the attachment / detachment of the optical fiber 30 is performed by connecting the light emitting unit side and the light receiving unit side of the optical fiber 30 as described above.
Since 30b is configured to be connected using the first and second optical fiber connectors 31 and 38 which can be easily fitted and fixed to the remote control side main body and the air conditioner main body side fitting portion only by sliding operation. The above system change is extremely easy.

Further, particularly, the fitting grooves 57, 57 of the second optical fiber connector 38 on the side of the air conditioner body 1 are provided with the fitting grooves 57, 57.
Since it is adapted to be slid and fitted from the rear side 8 side to the front side 9 side, as described above, the lower side of the air conditioner main body 1 can be set with the hook-shaped hooks 2, 2 as fulcrums. As shown by the phantom line in FIG. 2 (a), it rotates to form a gap on the wall surface 5 side, and the second optical fiber connector 38 on the side of the light receiving unit is used to form the gap by using the gap. The air conditioner main body 1 can be easily fitted only by engaging the main body side fitting grooves 57, 57 and thereafter pressing the air conditioner main body 1 against the wall surface portion 5 side in the opposite direction to the above using the weight. Therefore, it is very easy to attach / detach even though the light-receiving-side connecting portion of the optical fiber 30 is located at a considerably high position, and the rear side of the air conditioner body 1 is generally a place where attachment / detachment is extremely difficult. You can operate.

Further, when the optical fiber 30 is connected in such a manner and, for example, a remote control system via the optical fiber 30 is configured as shown in FIG. Since the 30 is surely hung vertically along the wall surface 5, it becomes easy to lock the remote controller 6 including the remote controller 6 side, and the appearance is beautiful.

On the other hand, in this case, for example, as shown in FIG. 9, only the optical fiber 30 is removed, and only the remote controller 6 is locked to the wall surface portion 5 immediately below the second light receiving portion 42 similar to the above as shown in the drawing. Considering the case, the second light receiving section 42 exists on the optical axis extension line 1 of the second light emitting section 22 in the locked state, and even the distance should be set within the reliability performance range. For example, even red visible light can be used in a sufficiently cordless state, and its position can be set easily by adjusting only the position in the width direction.

This is particularly convenient in the following usage environment.
For example, a plurality of or a plurality of types of air conditioners (including similar products such as air conditioners and air cleaners) may be simultaneously used at the same place in a place having a large ventilation capacity such as in a factory. Then, in such a case, assuming that a cordless remote control system is adopted, when a large number of people operate the air conditioner, the location of the remote controller 6 moves each time,
There may occur a situation where the correspondence between the air conditioner body 1 and the remote controller 6 is unclear, or the remote controller 6 itself is lost.

However, even in this case, as described above, each air conditioner body 1
If the remote controller 5 can be locked directly below the wall surface in response to the above, the correspondence relationship between the air conditioner body 1 and the remote controller 6 is always clear even though it is a cordless type. Rather than
There is no fear of loss.

Further, in the configuration of the above embodiment, the first light receiving portion 41 on the front side of the air conditioner body that is always used in a cordless state.
Is composed of an infrared light sensing type light receiving element,
A red visible light sensing type capable of arbitrarily selecting two control states, a first remote control state of a cordless state without using the optical fiber 30 and a second remote control state of a fiber cord method using the optical fiber 30. The second light receiving section 42 which employs the light receiving element is disposed on the lower surface of the air conditioner body 1 and closer to the wall as described above.

Therefore, regardless of day or night, generally speaking, the ambient light (visible light) whose light source position is always above the air conditioner body 1 does not directly enter the second light receiving section 42. It is especially convenient when the first remote control system that does not use the optical fiber 30 is adopted,
There is an advantage that the reliability can be improved.

(Effects of the Invention) As described above, the air conditioner of the present invention has the wall surface 5
A wall-mounted air conditioner main body 1 mounted on the air conditioner, and a light transmission type handheld remote controller 6 including a light emitting section for remotely controlling the air conditioner main body 1.
And the first provided on the front surface portion 9 of the air conditioner body 1
Light receiving portion 41, a second light receiving portion 42 provided on the lower surface portion 10 of the air conditioner body 1, and an upper end side of the second light receiving portion 42.
An optical fiber 30 whose lower end is detachably connected to the light emitting portion of the handheld remote controller 6 via connector portions 38 and 31, respectively, and transmits the light transmitted from the light emitting portion of the handheld remote controller 6. From the front side region of the air conditioner main body 1 in a cordless state without the optical fiber 30 and the optical fiber 30.
The air conditioner main body 1 in the fiber code state through the
In the air conditioner configured to be able to receive light from the respective lower regions of the above, the first and second light receiving portions 41, 42 described above are provided.
Is configured such that the front side first light receiving section 41 is an infrared light receiving section and the bottom side second light receiving section 42 is a red visible light receiving section, and the light receiving wavelengths are different from each other, and Correspondingly, the handheld remote controller 6 side light emitting unit is also configured to have two types of light emitting units having different emission wavelengths between the infrared light emitting unit 21 and the red visible light emitting unit 22. It is characterized by.

That is, in the configuration of the air conditioner of the present invention, in the case where the wall-mounted air conditioner main body 1 is remotely controlled by the handheld cordless remote controller 6 of the optical transmission system including the light emitting unit as described above,
The light receiving portions on the side of the air conditioner body 1 are provided at two locations on the front surface side and the lower surface side of the air conditioner body 1. Therefore, the air conditioner can be controlled not only from the front side transmission area of the air conditioner main body 1 but also from the lower side transmission area, and the transmission area is greatly expanded.

Moreover, in that case, the control from the front side transmission area is in a cordless state, and the control from the lower side transmission area is through the optical fiber 30 which has connectors 38 and 31 at both upper and lower ends and is detachably connected. The remote controller 6 can be detachably locked and attached to the lower end of the optical fiber 30 via the connector 31 even when there is no suitable place to fix the remote controller 6 on the wall surface side. .

If the optical fiber 30 is removed and the remote controller 6 is attached to the wall surface side, the same control can be performed in a cordless state.

Corresponding to the difference in the two signal transmission modes, the front side first light receiving section 41 on the side of the air conditioner body 1 is an infrared light receiving section having a high signal transmission efficiency in the air, and the lower surface thereof. The second side light-receiving unit 42 is configured as a light-receiving unit for red visible light having a high signal transmission efficiency in the optical fiber, each having a different light-receiving wavelength, and the hand-held remote controller 6 side also corresponds to them. There are provided light emitting units 21 and 22 having different emission wavelengths for infrared light and red visible light. Therefore, it is possible to secure high signal transmission efficiency corresponding to the respective signal transmission modes of light, and it is possible to reliably and accurately transmit signals.

Therefore, according to the configuration of the present invention described above, the degree of freedom of the installation location on the air conditioner main body side eventually increases as the operable area of the cordless remote controller increases, and the conventional location of a person as in the conventional case. The operable area is specified with the center as the center, and the restrictions on installation, such as when the front side light-receiving part of the air conditioner main body 1 is always associated with the specified position, are remarkably relaxed, and installation work is much easier. become.

In addition, the light-emitting units 21 and 22 and the light-receiving units 41 and 42 are configured by selecting light having a wavelength with good transmission efficiency corresponding to each signal transmission mode of the cordless state without the optical fiber and the fiber code state through the optical fiber. Therefore, the operation performance is highly reliable. Further, since the light receiving portion 42 on the lower surface side of the air conditioner body 1 is coupled to the optical fiber 30 via the connector 38 and faces downward, it does not pick up incident light from the upper side, and accordingly malfunctions due to ambient light. Therefore, the effect of improving operational reliability can be maintained higher.
