Description

Description: TECHNICAL FIELD The present invention relates to an air conditioner equipped with a remote control device.

(Prior Art) Recently, even in an air conditioner such as an air purifier or an air conditioner for cooling / heating, a remote control system for freely operating the air conditioner body from an arbitrary remote position or a predetermined specific remote position. Has been adopted.

Then, as the remote control system in which the operation position can be arbitrarily selected, for example, a handheld type cordless type remote controller including a light emitting unit in the operating device on the hand side is used, and a signal from the light emitting unit of the handheld remote controller is used. A cordless transmission system based on an optical transmission system is generally adopted in which the transmitted light is received by a transmitted light receiving section provided on the air conditioner main body side through a spatial transmission path, and while a cordless transmission system is generally adopted, As a remote control system that is remotely operated from a specific position, for example, an optical fiber is used as a signal transmission path, and control is performed by connecting the light receiving unit of the air conditioner body and the light emitting unit of the remote controller side through the optical fiber. Made fiber Code transmission system is generally employed (see, for example, JP-A-60-42541).

The remote control device of the cordless transmission system is extremely convenient because it can control its operating state freely from any position where it can be transmitted to the air conditioner body in a completely free state. Since the controller is freely portable, it can sometimes be lost.

Therefore, as a countermeasure against such a case, for example, the remote controller on the hand side may be held in a state of being connected to the air conditioner main body side in some way except when using the cordless.

In the case of the above-mentioned prior art, for example, as shown in FIG. 1 of the above publication, the hand side remote controller having the light emitting portion as described above is used as a controller that can be commonly used in both the cordless state and the fiber cord state. Other than when used in a cordless state, it can be attached and fixed arbitrarily to the optical fiber side attachment part that communicates with the light receiving part of the air conditioner body to prevent loss of the remote controller on the hand side and the same. We have realized an increase in variations of remote control systems in products (fiber cord transmission systems can be used in addition to cordless transmission systems).

(Problems to be Solved by the Invention) With the above-described configuration of the related art, it is possible to realize two types of remote control systems, a cordless transmission system and a fiber cord transmission system, and to prevent loss of the remote controller on the hand side. Is a big advantage.

However, the installation form of the air conditioner main body is not limited to the case of the wall-mounted type as described above, and depending on the installation place and the usage form on the user side, the user can directly operate the air conditioner main body, for example, a stand. Often, a mold (see FIG. 2b) or a pond type (see FIG. 2e) is used. In such a case, it is not appropriate to combine the fiber cord transmission system as in the above-mentioned conventional technique, and it is rather preferable that the fiber cord transmission system is directly connected to the air conditioner main body side.

However, when the remote controller of the optical transmission system is detachably attached to the main body of the air conditioner, how to configure the signal transmission path of the coupling portion becomes an important issue.

In this case, generally, a cup of a recess for storing a remote controller is formed by combining a connector member for attachment / detachment such as an optical connector and an optical transmission line such as an optical fiber at an appropriate position that is most convenient for the operation of the air conditioner body. It is conceivable to install the optical connector on the ring portion and connect the optical connector to the light receiving element surface of the light receiving portion for cordless transmission through an optical fiber.

However, in such a case, first, an optical connector and an optical fiber are required, the structure is complicated, the number of parts is increased, and at the same time, an extra installation space for arranging them must be formed. There are drawbacks that increase design complexity.

Further, in general, the light receiving section is installed with the light receiving element surface facing the front surface of the housing, mainly considering the light receiving accuracy in the cordless state, so that the connection with the optical fiber drawn from the other direction as described above is performed. Is not easy.

Therefore, in that case, if it is inevitable to adopt the above-mentioned configuration, two sets of light receiving parts are inevitably required, which is uneconomical.

(Means for Solving Problems) The present invention has been made for the purpose of satisfying the above-mentioned demands, and for transmitting a control signal as shown in, for example, FIG. 1, FIG. 3, and FIG. An air conditioner including a handheld remote controller 6 including the light emitting unit 21 and a light receiving unit 41 corresponding to the light emitting unit 21 of the handheld remote controller 6 and receiving a control signal transmitted from the light emitting unit 21. The air conditioner body 1 is configured to be remotely controlled by the remote controller 6 in a cordless state, and the remote controller 6 is provided adjacent to the light receiving section 41 of the air conditioner body 1. Of the remote controller 6 when the remote controller 6 is housed in the housing recess 51. In a main body of an air conditioner configured to operate 21 and the light receiving section 41 of the air conditioner main body 1 by photo coupling to operate the air conditioner main body 1 in a direct control state, a light receiving element 46 of the light receiving section 41. The surface is the case 11 of the air conditioner body 1
The recessed portion 51 for accommodating the remote controller is installed at a position retracted inward by a predetermined distance from the light-receiving filter 44 located on the outer surface, and the waveguide space linearly faces the light-receiving filter 44.
The light receiving element 46 which directly forms the light from the light emitting portion 21 of the remote controller 6 which forms the 45 and is housed in the remote controller housing recess 51 through the waveguide space 45.
Is configured to receive light.

(Operation) According to the means for solving the problems of the present invention, the remote controller 6 on the hand side including the light emitting portion 21 for transmitting the control signal and the light receiving portion 41 corresponding to the light emitting portion 21 of the remote controller 6 are provided. The air conditioner main body 1 provided therein is connected in a cordless state for remote control, while the air conditioner main body 1 receives the light transmitted from the remote controller 6 in the cordless state. A storage recess 51 for the remote controller 6 is formed adjacent to the remote controller 6 so that the remote controller 6 can be stored in a photo-coupled state so as to be directly controllable.

The surface of the light receiving element 46 of the light receiving section 41 adjacent to the recess 51 for accommodating the remote controller is the air conditioner body 1
A waveguide space 45, which is installed at a position retracted inward by a predetermined distance from the light receiving filter 44 located on the outer surface of the housing 11 and linearly faces the remote controller housing recess 51 with the light receiving filter. The light receiving element for directly receiving the light from the light emitting portion 21 of the remote controller 6 in the recess 51 for accommodating the remote controller via the waveguide space 45 is formed.
It is designed to allow the 46 to receive light for direct control.

(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 electronic dust collecting element configured to have a dust collecting cell, and the dust collecting cell surrounds a high voltage generating part of an ion generating part (corona discharge electrode) and the high voltage generating part. 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 (Fig. 2c), [4] Ceiling embedded type (Fig. 2d), [5]
It is constructed so as to be compatible with all installation methods of the Pon-type (Fig. 2e). First, as shown in Fig. 2 (a), the rear surface of the external housing 11 as a wall-hanging type corresponding structure. On the left and right sides of the side upper end portion, hanging flanges 4 and 4 having engaging holes 3 and 3 that engage with hook-shaped hooks 2 and 2 fixed to the wall surface portion 5 side are attached. The air conditioner main body 1 is hung on the wall surface side hook-shaped hooks 2 and 2 via the flanges 4 and 4 so that the air conditioner main body 1 is installed at a position of a wall surface portion 5 at a predetermined height in the room. In the installed state, by pulling the lower surface 10 side forward, it can be rotated by a predetermined angle to the state of the imaginary line shown in FIG. 2 (a) (this point will be described later in detail).

On the other hand, reference numeral 6 is a handheld remote controller for controlling the operating state of the air conditioner body 1 (ON / OFF of power supply, H / L adjustment of fan strength, etc.). 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 is provided on the front end side 62A and the rear end side 62B and has different emission wavelengths, for example, an LED.
A first light emitting portion 21 and a second light emitting portion 22 are provided respectively. The transmission control circuit of the transmission control circuit board 62 projects from the keyboard plate 64 side to the front side operation panel surface 61a via the operation button through holes 65a, 65b, 65c, 65d of the remote control box 61. Some operation buttons 25a, 25b, 25
A keyboard circuit that operates in response to the operation of c and 25d and outputs operation information, a pulse encoder circuit that encodes and outputs the information content according to operation information from the keyboard circuit, and a light source frequency of ambient light A pulse generating circuit for generating a pulse signal having a predetermined reference oscillation frequency different from that, and converting the pulse signal from the pulse generating circuit into a burst signal encoded according to the operation information by the encode signal of the pulse encoder circuit. And a mixing circuit for outputting the same, which corresponds to the burst signal output of the mixing circuit.
Let 2 emit light arbitrarily. Here, the first light emitting unit 21
Is, for example, an infrared light emitting part using a gallium / arsenic infrared LED with a wavelength of about 940 nm, and the second light emitting part 22 is a red visible light emitting part with a wavelength of about 660 nm using, for example, a gallium / phosphorus red LED. Has been formed. These first and second
It is known that the signal transmission efficiencies of the light emitting units 21 and 22 greatly differ depending on their transmission modes. For example, in the case of the first light emitting section 21 using the gallium / arsenic infrared LED, the second light emitting section 21 using 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 light emitting section 22 of FIG. 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 first light emitting portion 21 side of the inside is exposed to an acrylic transparent window 26, and the first light emitting portion 21 is exposed through the transparent window 26.
Infrared rays of the above-mentioned wavelength are irradiated in the direction of the optical axis in a fiberless state. In addition, the second light emitting unit 22
Is adapted to be securely fixed by being fitted in the central 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, and to be securely fixed at the front position. One end (end on the light emitting unit side) 30 of an optical fiber 30 described later, which is located on both sides of the bottom space of the box and faces each other.
First fitting grooves 32, 32 are provided in which the locking flange piece 34 of the first optical fiber connector 31 attached to a is fitted in a sliding state from the upper side. Further, the remote control cap 63 that is fitted and integrated with the remote control box 61 from the back side is the remote control box 61.
The first optical fiber connector 31 described later, in which the front portion is cut out in a concave shape from the portion corresponding to the first fitting grooves 32, 32 of
Forming a fitting space 460.

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. Is integrally formed on the front side of the remote control box main body so as to extend laterally.
It is composed of a locking flange piece 34 that fits in 2. 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, and a C-shaped ring-shaped stopper 35 is fitted from above the connector main body 33 in the middle of the optical fiber insertion hole 34a. A slit 36 for forming is formed, and the stopper 35 is fitted into the slit 36 from above, and the sliced surface 37a is inserted into the optical fiber insertion hole 34a and is aligned with the outer surface of the flange piece 34. The connector body 33 is fixed to the end portion 30a of the optical fiber 30 on the light emitting portion side. 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. The reference numeral 39 designates a similar connector body, and 40 designates a flange piece.

Further, the remote control cap 63 has a battery storage recess 63.
a is formed, and the batteries 80, 8 are placed in the battery storing recess 63a.
In the state where 0 is stored, the battery cover 81 is detachably attached.

On the other hand, a first light receiving 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 casing 11 of the air conditioner main body 1, and a first light receiving portion 41 is provided on the lower surface portion 10. A second light receiving portion 42 corresponding to each of the two light emitting portions 22 is provided, and each of these light receiving portions 41, 42 comprises a photodiode whose sensitivity is set corresponding to the wavelength of each of the light emitting portions 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.

On the left side of FIG. 6 of the first light receiving portion 41, there is formed a remote control accommodating recess 51 for accommodating the above-mentioned remote controller 6 in the rear direction. The remote-control accommodating recess 51 is provided adjacent to the first light-receiving section 41 as shown in the figure, while the front operation panel surface 61a of the remote controller 6 is accommodated in the air conditioner when the remote controller 6 is accommodated. The depth is set so as to be substantially flush with the wall surface of the front surface portion 9 of the machine body 1, and in this state, the first or second light emitting portion 21 of the remote controller 6 is formed. , 22 is opposed to the reflecting surface 47 via the waveguide space 45 of the first light receiving portion 41. For example, this is shown in FIG.
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.
The first light-emitting unit is also used when the left and right sides of the
Only by reversing the positional relationship between 21 and the second light emitting portion 22, the changed facing relationship between the light emitting portion and the reflecting surface 47 is surely maintained, and characters can be displayed in an 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 first light receiving element is configured to transmit only infrared light from the first light emitting portion 21 of the remote controller 6 which is always used in a cordless state and to pass through a part of the waveguide space 45. Lead to 46. The waveguide space 45 is formed between the optical filter 44 and the first light receiving element 46, and linearly faces and communicates with the remote control accommodating recess 51. Therefore, when the remote controller 6 is housed in the remote control housing recess 51 as described above, the optical axis of the first light emitting section 21 or the second light emitting section 22 of the remote controller 6 is the waveguide space. Corresponding coaxially with 45, the light from the first or second light emitting portion 21, 22 is directly transmitted to the first light receiving element 46 and the reflecting surface 47 through the waveguide space 45 with an extremely short optical path distance. Lead. The light guided to the reflecting surface 47 is, of course, reflected by the reflecting surface 47 and is incident on the first light receiving element 46 at the same time as the direct incident light.
The amount of light incident on the light receiving element 46 is increased. Therefore, even if the waveguide space 45 is formed parallel to 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 incident light amount can be secured and the optical path distance can be secured. Since there is an extremely short time, there is almost no time delay between the direct light and the reflected light and chattering does not occur, so that reliable operational performance and reliability can be secured.

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 is made of a transparent material such as acrylic. A waveguide space similar to the above with a plate installed
Of course, it is possible to form 45.

However, in that case, when the second light emitting unit 22 for infrared visible light is selected as the light emitting unit facing the reflecting surface 47, the frequency of the light emitting unit is different, and therefore, 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 58 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 receiving 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 via the optical fiber 30 and transmits the control signal, are connected by two kinds of remote control systems. In addition, in addition to the direct control system described at the beginning, there is a total of three types of operating state control systems, and by attaching or detaching the optical fiber 30 to or from any one of them, a remote control system can be obtained. By attaching and detaching the controller 6 to and from the air conditioner body 1, It is possible to select the reason. Moreover, the attachment / detachment of the optical fiber 30 can be easily performed by sliding the light emitting unit side and light receiving unit side connecting end portions 30a and 30b of the optical fiber 30 as described above, simply by the sliding operation. Since the connection is made by using the first and second optical fiber connectors 31 and 38 which can be fitted and fixed to, 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 is generally located on the back side of the air conditioner body 1 which is extremely difficult to attach / detach. 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, in a place having a large ventilation capacity such as in a factory, a plurality of or a plurality of types of air conditioners (including similar products such as air conditioners and air cleaners) may be used at the same place at the same time. 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 6 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.

(Effect of the Invention) As described above, the air conditioner of the present invention includes the handheld remote controller 6 including the light emitting unit 21 for transmitting a control signal, and the light emitting unit 21 of the handheld remote controller 6. The air conditioner main body 1 is provided with a light receiving portion 41 that receives the control signal transmitted from the corresponding light emitting portion 21, and the air conditioner main body 1 is remotely controlled in a cordless state by the remote controller 6. On the other hand, the recessed portion 51 for storing the remote controller is formed adjacent to the light receiving portion 41 of the main body 1 of the air conditioner, and the remote controller 6 is stored in the recessed portion 51 for storing. The light emitting unit 21 of the controller 6 and the light receiving unit 41 of the air conditioner main body 1 are photo-coupled to each other and the air conditioner main body 1 is directed. In the air conditioner configured to be operated in a controlled state, the surface of the light receiving element 46 of the light receiving unit 41 is located at a predetermined distance from the light receiving filter 44 located on the outer surface of the housing 11 of the air conditioner body 1. The recessed portion 51 for accommodating the remote controller is formed between the light receiving filter 44 and the recessed portion 51 for rectilinearly facing, and the recessed portion for accommodating the remote controller is formed through the waveguide space 45. It is characterized in that the light from the light emitting section 21 of the remote controller 6 housed in the 51 is directly received by the light receiving element 46.

That is, in the configuration of the air conditioner of the present invention, the near side remote controller 6 including the light emitting unit 21 for transmitting a control signal and the light emitting unit 21 of the remote controller 6 are provided.
The air conditioner main body 1 having the light receiving section 41 corresponding to is connected in a cordless state for remote control, while the air conditioner main body 1 transmits data from the remote controller 6 in the cordless state. The remote controller 6 is adjacent to the light receiving section 41 that receives light.
The storage recess 51 is formed so that the remote controller 6 can be stored in a photo-coupled state so as to be directly controllable.

The surface of the light receiving element 46 of the light receiving section 41 adjacent to the recess 51 for accommodating the remote controller is the air conditioner body 1
A waveguide space 45, which is installed at a position retracted inward by a predetermined distance from the light receiving filter 44 located on the outer surface of the housing 11 and linearly faces the remote controller housing recess 51 with the light receiving filter. The light receiving element for directly receiving the light from the light emitting portion 21 of the remote controller 6 in the recess 51 for accommodating the remote controller via the waveguide space 45 is formed.
It is designed to allow the 46 to receive light for direct control.

Therefore, according to the present invention, the handheld remote controller 6 on the hand side allows the control system for both the cordless state and the direct control directly connected to the air conditioner main body to be arbitrarily set according to the installation form of the air conditioner main body 1 or the like. Of course you can choose,
The structure of the air conditioner body 1 side light-receiving part 41 and the remote controller housing recess 51 that realizes the direct connection of the remote controller to the air conditioner body 1 is as follows. While being provided adjacent to each other, the surface of the light receiving element 46 of the light receiving portion 41 is set back from the front surface of the housing 11 of the air conditioner body 1 by a predetermined distance from the light receiving filter 44, so that The light emitting portion of the remote controller 6 housed in the remote controller housing recess 51 between the light receiving filter 44
A waveguide space 45 having an extremely short optical path that linearly faces 21 is formed so that the light from the light emitting portion 21 of the remote controller 6 is substantially separated without passing through an intermediate transmission medium such as an optical connector or an optical fiber. Since it is possible to directly receive light by utilizing, there is no chattering due to a time delay as in the case of forming a long and orthogonal waveguide path to indirectly receive reflected light and scattered light. Moreover, it is not necessary to form a dedicated waveguide path. Therefore, the structure is simple and unnecessary components such as a reflector and a shield member are not required, and the structure can be realized extremely easily. Further, since the light receiving element 46 for the cordless transmission system can be shared as it is, a single light receiving element is sufficient, and the cost advantage is great.
