The operation of the moving panel 9 having the shutter mechanism 31 described above will be described with reference to FIGS. First, FIG. 11 shows a state in which the moving panel 9 is closed. In this state, the upper end of the plate gear 68 of the rack 63 meshes with the third gear 72, the lower end of the rack 63 contacts the stepped portion 47 of the decorative cover 3, and the closed state is maintained. Next, in FIGS. 10 and 11, the operation signal is the terminal 6
9 is instructed to the stepping motor 64, the stepping motor 64 operates and the rotational torque is changed to the third gear 72 via the first gear 70, the second gear 71, and the belt 73.
Is transmitted to At this time, the drive mechanism 59 and the connecting mechanism 6
Since the second gear 71 of 0 is connected by the connecting rod 61,
The same rotation torque is transmitted to the third gear 72 of the drive mechanism unit 59 and the coupling mechanism unit 60. The rotational torque transmitted to the two third gears 72 is converted into vertical torque by the plate gear 68, and the moving panel 9 attached to the rack 63 can be moved upward. FIG. 10 shows a state in which the moving panel 9 is pulled up and the first suction section 7 is opened. In the present embodiment, the moving path Z of the moving panel 9 and the rack 63 is set to the moving panel 9
And the rack 63 has an arc shape that substantially matches the side shape of the rack 63, and is set so that the center of the moving panel 9 is the frontmost portion in the closed state. Therefore, the moving panel 9 can be pulled up along the arcuate movement trajectory Z from the position shown in FIG. 11 to the upper diagonal rear side shown in FIG. In this opened state, the lower end of the plate gear 68 of the rack 63 is located at the third gear 7.
The large curved surface of the heat exchanger 10a and the front panel 4 in which the moving panel 9 is largely inclined rearward so that the upper end of the moving panel 9 is in contact with the ceiling of the decorative cover 3 behind the stepped portion 47 of the decorative cover 3. It is stored between 35. The guide plate 7 formed on the decorative panel 4
5 is formed in an arc shape along the movement trajectory Z. Further, by providing guide plates similar to the guide plate 75 on both sides of the rack 63 shown in FIG. 11, the movement of the moving panel 9 can be improved.

Further, the first suction portion 7 and the second suction portion 12
The width D1 of the housing surface formed between the moving panel 9 and
Since it is set to be larger than the width (height) D2 of the housing surface, a storage space for hiding and storing the moving panel 9 in the indoor unit 1 is formed at the rear portion of the width D1 of the housing surface.
Therefore, in the open state, the moving panel 9 is not exposed to the exterior of the blowout portion 5 or the indoor unit 1, so that the design can be improved.

Returning to FIG. 7, the filter 11 is formed on both inner wall surfaces and the center of the decorative cover 3 and is supported by the guide rails 76, and the first suction portion 7, the second suction portion 12, and the third suction portion 7 are supported. It is arranged between the part 13 and the heat exchanger 10. The filter 11 is provided with a filter cover 8 on the lower front surface corresponding to the first suction portion 7 and an air purifying filter 30 at a position behind the intersection P1.

The structure of the filter 11 and the cover 8 is shown in FIG.
~ It demonstrates with reference to FIG. In FIG. 9, in this embodiment, the filter 11 is formed by heat-sealing a dense net 11a formed of PP resin which is divided into two parts on the left and right sides and a frame 11b. Needless to say, the net 11a and the frame body 11b may be integrally molded, or another flexible resin material may be used. In particular, the appearance can be improved by forming the filter 11 by, for example, injection so that the unevenness of the net 11a and the frame 11b is reduced and a uniform curved surface is formed as a whole. If such an integral filter is adopted, the first suction portion 7 when the moving panel 9 is opened without attaching the cover 8 is provided.
The appearance inside can be improved. This filter 11
As shown in FIG. 14, the first suction portion 7, the second suction portion 12, and the third suction portion 13 are substantially the openings 5 that are open.
It is arranged so as to conceal 8, 12a and 13a. The cover 8 has a plurality of openings 77 that are rougher than the filter 11 on the front surface.
Is formed into a punching shape, a reinforcing rib 78 is formed on the inner circumference, and a mounting rib (not shown) formed on the reinforcing rib 78 is fitted into a mounting hole (not shown) formed on the frame 11b so as to be detachably mounted. . 11A shows a 3 mm square square opening 77 formed at a 4 mm pitch, and FIG. 11B shows a regular hexagonal opening 77 having a parallel line width of 3 mm.
Are formed at a pitch of 4 mm. According to the embodiment of FIG. A, an aperture ratio of 54% is obtained, and according to the embodiment of FIG. B, an aperture ratio of 64% is obtained. In this embodiment, the shape of the opening 77 shown in FIG. B is adopted, and the cover 8 is a resin molded product, but it may be formed of a metal material or another material. Further, it is preferable that the windward side of the opening 77 is tapered to reduce air resistance and improve the flow of wind.

As described above, in this embodiment, the filter 11 is used.
The cover 8 is coarser than the filter 11 and has a double structure in the front part, so that the cover 8 catches large dust.
Fine dust can be captured by the filter 11. Further, by making the cover 8 have a flat punching shape, it is possible to improve the design effect by eliminating the impression as an opening and making the first suction section 7 into a flat shape conforming to the large curved surface 35. Further, the cover 8 has a reinforcing rib 78.
As a result, a space 79 is formed between the filter 11 and the filter 11. Therefore, the indoor air that has passed through the cover 8 can be uniformly rectified and sucked from the filter 11. Therefore, even if the cover 8 is partially clogged, the efficiency of the filter 11 can be improved. Further, the space 79 makes it difficult for the filter 11 to be seen through the cover 8, so that the design can be improved. Further, since the cover 8 is detachably attached to the filter 11, it can be detached from the indoor unit 1 together with the filter 11 and cleaned independently.

Further, in this embodiment, the air cleaning filter 30 can be attached to obtain the air cleaning function in addition to the cooling and heating. The air purifying filter 30 has the same structure as the cover 8 and is detachably attached to the filter 11.
Therefore, it is easy to remove it from the indoor unit 1 together with the filter 11 and replace it with a new one. Also,
Since the air cleaning filter 30 is arranged in the space behind the intersection P1, it is possible to reduce the size of the device. Further, the arrangement of the filter 11 of this embodiment is the main 3
Since it is not directly provided between the two suction portions and the heat exchange, the ventilation resistance of the suction portions is reduced and a large opening area is obtained in terms of function, and the airflow is slow behind the intersection point P1. By passing, the cleaning efficiency of the air cleaning filter 30 can be improved.

Returning to FIG. 7, the display portion 14 and the light receiving portion 15 provided on the decorative cover 3 are provided on the inner wall surface of the step portion 47, and the display portion 14 is considered in view of wide range from a distance and from the left and right. Is mounted in the center of the vertical surface, and the light receiving portion 15 is mounted in the center of the inclined surface so that light can be received from a remote place, a left and right, and a wall-mounted remote controller. 80
Is a piping space for laterally piping the refrigerant pipe 28 formed at the lower part of the back surface using the rear ventilation surface 53b.

Next, the operation and operating method of the air conditioner according to this embodiment will be described with reference to FIGS. First, referring to FIG. 15, the indoor unit 1 according to the present embodiment.
Includes a control board 250 in the electrical equipment box 25, and a microcomputer 251 provided on the control board 250 operates a fan motor 18, a stepping motor 64 of a shutter mechanism section 31, and a stepping motor 24 for operating the wind direction plates 6a and 6b. Switch 2 for detecting movement of moving panel 9
52, room temperature thermistor 253, indoor heat exchange thermistor 25
4, the display unit 14 and the like receive the operation signal from the remote controller 1
5, the indoor unit 1 is integrally controlled. The control board 250 is also connected to an outdoor unit (not shown), the solenoid valve 10d, etc., but they are omitted here. This driving operation will be described with reference to FIG.

First, in the operation stopped state, the indoor unit 1
The wind direction plates 6a and 6b and the moving panel 9 are closed. When the remote controller issues an operation start instruction operation (201), the remote controller transmits an automatic operation mode signal if the automatic operation is selected, and if the manual operation is selected, the preset temperature and cooling / cooling A signal such as heating is transmitted (202). The microcomputer 251 is the light receiving unit 1
When the signal is received via step 5, when the automatic operation mode signal is received, the operation mode is automatically set through the room temperature thermistor 253 (203). The mode is set as the operation mode (204), the operation state is displayed on the display unit 14, and the preliminary operation is started (205). In this preliminary operation, hot keeping during heating is mainly performed. When the microcomputer 251 starts the preliminary operation and the operation preparation is completed, it sends an operation signal to the stepping motor 24 and the stepping motor 64. The stepping motor 24 opens the wind direction plates 6a and 6b to a predetermined angle set in advance in accordance with the operation mode. The stepping motor 64 moves the rack 63 upward to house the moving panel 9 in the indoor unit to a predetermined position shown in FIG. 10 (206). In this step 206, the wind direction plates 6a and 6b and the moving panel 9 are
Simultaneously operate, and the completion of the operation is detected by the switch 252. Next, the microcomputer 251 sets the fan motor 18
(207), the compressor (208) is operated, and normal operation is started (209). When the microcomputer 251 determines the operation stop according to the operation stop instruction from the remote controller or the set operation mode such as the timer (210), it stops the compressor and the fan motor 18 (211), and the stepping motor 24 and the stepping motor 64. Then, the wind direction plates 6a and 6b and the moving panel 9 are simultaneously operated to the original closed state (212), the operation display lamp is turned off and the operation is stopped (213). In addition,
When the stepping motor 64 is operating, the microcomputer 251
That is, in order to indicate that the moving panel 9 is moving, the display unit 14 may be blinked in accordance with the operation speed.

In the present embodiment, the fact that a driving instruction is given is displayed on the display unit 14, and the operations of the wind direction plates 6a and 6b and the moving panel 9 are interlocked with the fan motor 18 to change the blowing state. As you can see, the wind direction plates 6a, 6
I tried to solve the question that air was not blown even though b and moving panel 9 were open, but the operation ON signal (20
It is possible to formally express that a driving instruction has been given by 1) or by setting the open state when setting the driving mode (203, 204). Further, in the above-described embodiment, the operation of the wind direction plates 6a and 6b and the moving panel 9 was performed at the same time. Good.

Also, in this embodiment, the moving panel 9 is used.
Is controlled to be closed in the stopped state and fully opened in the operating state. However, the moving panel 9 is provided with means for converting the rotation speed of the fan motor 18 into the moving amount of the moving panel 9 so as to correspond to the blowing amount. May be controlled.
For example, in the light wind operation, the moving panel 9 is closed, and the indoor air is sucked from the second suction section 12 and the third suction section 13. In the medium wind operation, the moving panel 9 is partially opened and the first suction section is opened. In addition, the moving panel 9 is fully opened and the three sucking portions are sucked in during strong wind operation. In this way, the wind noise from the first suction section arranged in the front is reduced, so that quiet operation can be performed.

Next, a method of attaching / detaching the filter 11 will be described. In this embodiment, an exchange mode for attaching and detaching the filter 11 is provided. First, the exchange mode button provided on the remote controller is operated to transmit a signal. Microcomputer 25
In step 1, the stepping motor 64 is operated to fully open only the moving panel 9. In this state, the user removes the front panel 4 through the handle recess 37 and holds the opened filter 11 from both sides by hand to hold the indoor unit 1
You can easily pull it out from. At this time, filter 1
Since the cover 8 and the air purifying filter 30 are attached to 1, the three members can be removed by one operation. Further, since the filter 11, the cover 8 and the air cleaning filter 30 are configured to be detachable, they can be detached and cleaned independently. Therefore, unlike the conventional example, it is not necessary to remove and clean the front panel and the filter on which the suction slit is formed. Further, in this embodiment, since the cover 8 is a small member separated from the front panel 4, the handling and cleaning work is much easier than the conventional example. When mounting the filter 11, the cover 8 and the air cleaning filter 30 are mounted at predetermined positions, mounted along the guide rails 76, and the front panel 4 is mounted on the front surface. Then, by operating the exchange mode button provided on the remote controller again, the moving panel 9 can be returned to the original closed state. In addition,
In this embodiment, the remote controller is provided with the exchange mode button, but it may be provided in the indoor unit 1. For example, by providing the remote controller replacement mode button on the step portion 47 hidden by the front panel 4, it is possible to prevent the operation of the moving panel 9 while the front panel 4 is being attached / detached and improve the safety. The same effect can be obtained by providing a switch on the mounting rib 50 and the mounting hole 49 of the front panel 4 so that the attachment / detachment of the front panel 4 and the operation of the moving panel 9 are linked.

Next, another application example of the front panel 4 will be described. 17 is an external perspective view, FIG. 18 is a side view with the front panel 4 opened, and FIG. 16 is a partially enlarged view of the hinge portion. 17, in the indoor unit 1 according to the present embodiment, a filter 11, a moving panel 9, a display unit 14, and a light receiving unit 15 are arranged on the makeup cover 3, and the opening of the first suction unit 7 is arranged on the front panel 4. Only 58 is arranged. Therefore, the structure of the indoor unit 1 is changed by changing the front panel 4 to another front panel 4b, 4c or the like that shares the position and size of the opening 58 and the fitting portion shape with the decorative cover 3. It is possible to adapt to various series designs without doing so, and it is possible to easily select various front panels according to the indoor environment.

For example, the front panel 4b shown in FIG.
Is an uneven portion 81 that is continuous with the opening 58 at both ends of the opening 58 to give the first suction portion 7 a wide impression. The front panel 4c shown in FIG.
The concave groove 82 exposing the display portion 14 is formed into a thin line shape extending to the lateral width of the blowing portion 5, and both ends thereof are connected to the blowing portion 5 with a decorative line to give an accent to the most noticeable position and to blow the blowing portion 5 together. It can be designed to emphasize the size of.

FIG. 18 shows the front panel 4 which is attached to the decorative cover 3 so as to be openable and closable.
FIG. A is a side conceptual view with the front panel 4 open, FIG. B is a side conceptual view with the front panel 4 closed, and FIG.
FIG. 4 is a perspective view of a main part of a hinge part. In the drawing, the front panel 4 is detachably attached to the decorative cover 3 in the above-described embodiment, but in this embodiment, for example, the hinge portion 82 is provided in the upper fitting portion between the front panel 4 and the decorative cover 3. There is. Further, the hinge portion 82 has a rotation axis of 8
The moving panel 9 is provided so as to be located rearward of the upper end of the moving panel 9 when the moving panel 9 is stored.
Can be efficiently housed inside the upper part of the front panel 4 without increasing the outer shape of the main body, and the front panel 4 can be firmly supported because it is hard to see in the installed state. According to this embodiment, when the filter 11 is attached or detached, there is no problem in the place where the front panel 4 is placed. The hinge portion 82 has a structure in which the front panel 4 and the decorative cover 3 can be attached and detached, and further, by providing a locking means or a spring (not shown) for maintaining the opened state, the cleanability of the front panel 4 and the attachment and detachment of the filter 11 are performed. The handling property of can be improved.

Next, another application example relating to the operation of the moving panel 9 will be described. 19 and 20 show an embodiment in which the moving panel 9 is provided with vibration preventing means. FIG. 19 is a sectional view of an essential part of the moving panel 9 in an open state, FIG. 19 is a sectional view of an essential part of the moving panel 9 in a closed state, and FIG.
Reference numeral 0 is a cross-sectional view of an essential part of the moving panel 9 in which the first suction part 7 in the open state is looked up. In FIG. 19, in this embodiment, the moving panel 9 is pulled upward to provide the vibration preventing means 300 at a position where the moving panel 9 contacts the ceiling surface of the decorative cover 3, and the moving panel 9 is closed to close the rack 63. The vibration preventing means 301 is provided at the position where the lower end of the step abuts the step portion 47. The vibration preventing means 300, 301 may be a soft material such as rubber or a convex rib that acts to hold down the movement track Z from the lateral direction. For example, in FIG. A, the vibration preventing means 300 is made of a soft material, and the vibration preventing means 300 is appropriately arranged in the lateral direction of the first suction portion 7. According to this vibration preventing means 300, since the movement of the moving panel 9 is softly received and the moving panel 9 is pressed in the direction of the arrow, the vibration of the moving panel 9 during operation can be prevented. Further, in FIG. B, the vibration preventing means 301 having a concave cross section is made of a soft material, and the vibration preventing means 301 is
Are appropriately arranged in the lateral direction of the first suction section 7.
According to this vibration prevention means 301, the moving panel 9
Since the lower end of each is supported from the front-rear direction, for example, the moving panel 9 and the shutter mechanism section 3 due to vibration during transportation.
The damage of 1 can be reduced. Of course, when the mode of driving when closed is adopted, there is an effect of preventing vibration of the moving panel 9 during driving.

In this embodiment, in FIG. 20, a partition plate 302 is provided behind the upper end of the opening 58 of the first suction part 7 and the lower end of the moving panel 9 is pulled up when the moving panel 9 is pulled up. Is the upper end of the opening 58 and the partition plate 3
No. 02 opening portion 303 is provided with an appropriate gap 304 so as to be housed. According to this structure, since the user cannot pull down the housed moving panel 9, it is possible to reduce damage to the moving panel 9 and the shutter mechanism section 31 and to improve safety for the user. At the time of closing, the lower end of the moving panel 9 is housed in the main body, so that it cannot be forcibly pulled up. Further, in this embodiment, the reinforcing ribs 7 at the inner lower end of the moving panel 9 are used.
8 (shown in FIG. 13B), a convex rib 305 is provided, and a convex rib 306 is further provided on the lower end portion of the front surface of the moving panel 9. The convex ribs 305 and 306 are appropriately arranged in the lateral direction of the first suction section 7. In addition, the convex rib 306 is
Since the moving panel 9 is exposed from the opening 58 as the moving panel 9 moves, it is provided as small as possible in a portion in contact with the upper end of the opening 58 at the time of closing so as not to impair the design.
By adopting such a structure, the gap 304 through which a finger may enter can be reduced, and the bending of the moving panel 9 which is long in the lateral direction can be reduced to prevent vibration and chattering noise of the moving panel 9 during driving. Has the effect of In this embodiment, the convex ribs 305 and 306 are provided at the lower end of the moving panel 9, but similar convex ribs 305 and 306 are provided at the positions where the upper ends of the moving panel 9 come into contact when closed.
By providing the above, it is possible to reduce the same effect as described above when the door is closed and the obstacles when the paper is conveyed.

Next, FIGS. 21 to 23 show another embodiment relating to the operation control of the moving panel 9, and FIGS.
2 is a longitudinal sectional view, and FIG. 23 is an operation flowchart. 21, in the above-described embodiment, the opening / closing of the moving panel 9 is detected by the switch 252, but in this embodiment, the vibration preventing means 300, 30 shown in FIG.
ON / OFF switches 400, 40 in the same position as 1.
1 should be provided. By doing so, the microcomputer 251 moves the moving panel 9 upward from the state where the upper switch 400 is OFF and the lower switch 401 is ON, the lower switch 401 is OFF, and the upper switch 400 is ON. If so, the movement of the moving panel 9 is stopped. The reverse operation may be performed when closing. Therefore, according to the present embodiment, it is possible to easily recognize the position of the moving panel 9 and control the operation.

Further, as shown in FIG. 22, only the lower switch 401 may be provided. In this case, the microcomputer 251 detects the number of rotations of the stepping motor 64 by detecting the number of rotations of the stepping motor 64 from the home position when the lower switch 401 is in the home position and the switch 401 is in the off position. Try to specify the amount of movement. Further, when closed, the lower switch 401 is changed from the OFF state to the ON state, so that the microcomputer 251 recognizes that the moving panel 9 has returned to the home position and stops the stepping motor 64. Further, in this embodiment, the moving panel 9 is always operated at the start of the operation or at the restart of the operation.
Recognizes whether it is in the home position, and if it is not in the home position, the moving panel 9 in the home position is returned to perform the subsequent operations. For example, if the moving panel 9 is stopped midway due to some trouble, such as a power failure during operation, the microcomputer 2
51 operates to return the moving panel 9 to the home position. This operation flow will be described with reference to FIG. When the microcomputer 251 receives the operation start command, the microcomputer 251 checks (410) whether or not the switch 401 is in the ON state. 41
1), for example, proceed to the flow shown in FIG. If the switch 401 is OFF, the stepping motor 64
Then, an operation signal is transmitted to move the moving panel 9 downward (412). Then, the microcomputer 251 uses the switch 40 to confirm that the moving panel 9 is at the home position.
If it can be confirmed (413) in step 1, the subsequent operation (41
Proceed to 1). On the other hand, when it is not possible to confirm the return to the home position (413), for example, when an abnormal torque is detected in the stepping motor 64, or when the switch 401 does not become the ON state after a certain period of time,
The microcomputer 251 recognizes that an abnormality has occurred, and the display unit 14

15). By doing so, it is possible to reduce an accident caused by the movement of the moving panel 9.

FIG. 24 illustrates the difference in color luminosity between the filter 11 and the cover 8. In general, the indoor unit has a filter 11 for removing dust behind the suction section and a heat exchanger 10 behind it. From a functional perspective, a large opening ratio can be obtained and the performance can be improved by making the suction part an opening that exposes the filter 11 as it is. However, in an indoor unit installed indoors, if the suction part is adopted as it is,
The filter 11 that does not take aesthetics into consideration is exposed, and the heat exchanger can be seen through the filter 11 having a large aperture ratio, which is not suitable for the indoor installation environment. Therefore, in the above-described embodiment, the above problem is solved by providing the cover 8 on the front surface of the filter 11. However, the aperture ratio of the cover 8 is set to 65% with a substantially uniform opening, and the color (white) of the cover 8 is set. The brightness of the color of the filter 11 (dark gray) is set to be brighter in five or more steps in the generally known 10 steps, so that the filter 11 and the heat exchanger 10 arranged behind the cover 8 can be set. Can be made hard to see and the design and performance can be improved.

In FIG. 24, with the interior of the indoor unit 1 as the background, the heat exchanger 10, the filter 11, and the cover 8 represented by humans are sequentially stacked, and the lightness X1 of the color of the cover 8 is 5 or more than the lightness of the other colors. Figure a, which is the difference in brightness, and differences in brightness 1 to 4
Is a conceptually easy-to-understand explanation. When the lightness difference is large as shown in FIG. A, since the lightness X1 of the color of the cover 8 is brighter than the lightness X2 of the other colors, the presence of the cover 8 becomes clear, and the observer focuses on the cover 8. The other filters 11 and the like are hardly visible to the observer. On the other hand, when the difference in lightness shown in FIG. B is small, the respective viewers have the same appearance and the same presence, so that the observer focuses on any constituent element. That is, the observer can easily see the filter 11 and the like arranged behind the cover 8. However, in order to satisfy the above effect, if the opening ratio of the cover 8 is too large, for example, the filter 11 is entirely visible at an opening ratio of 100%, and if the opening ratio is too small, the above effect is satisfied. Also has a performance problem. Further, the above-mentioned effect is slightly affected by the tint of color. Therefore, the inventor has experimentally verified that the aperture ratio of the cover 8 is from 70% to 5 with substantially uniform aperture.
By setting the lightness of the color of the cover 8 to be brighter than the lightness of the color of the filter 11 by four steps or more, the filter 11 and the heat exchanger 10 arranged behind the cover 8 are set. Can be made hard to see and the design and performance can be improved.

As described above, according to this embodiment, the upper and lower surfaces and the front surface are rounded bodies formed by the large curved surfaces 33, 34 and 35, and the moving panel 9 is provided below the large curved surface on the front surface. Arrange the first suction section 7 provided,
By disposing the second and third suction portions 12 and 13 on the large curved surface 33 of the upper surface, which is hard to be noticed, and by arranging the blowing portion 5 provided with the wind direction plates 6a and 6b on the large curved surface 34 of the lower surface, the stopped state is obtained. Then, the first suction part 7 and the blowing part 5 arranged at the most noticeable position are moved to the moving panel 9 and the wind direction plates 6a and 6b.
It has a compact shape with a surface that harmonizes with the interior familiar with the wall surface in the installed state by closing it in the plane, and in the operating state, the moving panel 9 is stored in the indoor unit 1 for the most efficiency. The first suction portion 7 which is fully opened at a good position, and the second and third suction portions 12 on the upper surface,
The indoor air can be efficiently sucked in by 13 and can be blown out from the blowing section 5 provided with the wind direction plates 6a and 6b for controlling the angle according to the operation mode. In particular, the first suction part 7
Since it is closed by the moving panel in the stopped state, it is possible to improve the cleanability without dust collecting on the grill unlike the conventional case. Moreover, since the inside of the first suction portion 7 is composed of the front panel 4 and the punching-shaped cover 8 and the filter 11 which are separated from each other, the first suction portion 7 can be seen in a planar manner while obtaining a large opening ratio. Since it is possible, it can be made inconspicuous and the cleanability can be improved.
Further, it is possible to reduce vibrations and noises caused by the movement of the moving panel 9, as well as obstacles.

[Other Embodiments] FIGS. 25 to 43 show another embodiment according to the present invention.

First, FIGS. 25 and 26 are external views showing another embodiment relating to the arrangement of the suction portion. In FIG. 25,
In the indoor unit 1 according to this embodiment, the first suction portion 7 is arranged at the center in the vertical direction of the large curved surface 35 formed at the center of the front surface, and the moving panels 9a and 9 are divided into upper and lower parts.
b is stored separately in the vertical direction. According to this embodiment, the moving panels 9a, 9b can be made thin to reduce the movement amount thereof, and the distance between the first suction section 7 and the second suction section 12 can be reduced to make the first, 2nd, 3rd
The indoor air sucked from the suction portions 7, 12, 13 can be sucked uniformly and efficiently through the heat exchanger 10.

Further, in FIG. 26, in the indoor unit 1 according to this embodiment, the first suction portion 7 is arranged above the large curved surface 35 formed in the center of the front surface, and the moving panel 9 is moved downward. It is something to store.
