2. Description of the Related Art A conventional air conditioner, for example, in a wall-mounted air conditioner, has a suction grill formed on the front surface of a casing having a ventilation passage having a filter, a heat exchanger and a blower fan inside. In general, a structure is provided in which a suction section is provided, and the room air sucked from the suction section and the suction section on the upper surface is blown out from the blowing section provided on the bottom surface. In these conventional examples, the front surface of the housing is made of a resin-molded front panel having a wall thickness of about 2.5 mm to 3 mm, so that the housing is made steel and the front suction grille is designed. In consideration of the protection of the internal mechanism, the steel property of the housing, and the problems in molding, the wall thickness is made thicker than the front panel and integrally molded. The conventional example is, for example, "Model RAS-259FX" implemented by Hitachi, Ltd. in 1995.

On the other hand, if the opening area of the front suction part is increased in order to improve the heating / cooling performance, the inside can be seen and the appearance is impaired. Therefore, in the conventional example, the size of the suction portion on the front surface is reduced by providing a large opening on the upper surface. However, as a method of increasing the amount of air to improve the cooling / heating performance, there is a method of reducing the air resistance in addition to increasing the opening area. For example, in the conventional example,
Since the wall thickness of the opening is larger than the wall thickness of the front panel, the amount of intake air is reduced by the amount of this air resistance, so the suction part had to be made larger.

A first object of the present invention is to provide an air conditioner capable of reducing the ventilation resistance and improving the performance without impairing the design.

A second object of the present invention is to provide an air conditioner capable of reducing the ventilation resistance and improving the performance while maintaining the strength.

And a belt 73 that transmits the Reference numeral 74 denotes a rack support portion that supports the sliding groove 66 from both sides to improve the meshing between the third gear 72 and the plate gear 68 and guides the rack 63 in the vertical direction. Further, reference numeral 75 denotes a guide rail formed on the decorative cover 3 on the movement track Z of the rack 63, which supports the rack 63 together with the rack support portion 74 and guides the movement track of the rack 63. In this embodiment, the guide rail 75 is provided to move the rack 63 stably, but the same effect can be obtained by enlarging the rack support portion 74 in the vertical direction. The guide rail 75 may not be provided if it is not necessary to reduce the amount of movement of the rack 63 or obtain particularly high accuracy. Further, in this embodiment, the belt 73 is provided so that the belt 73 is separated from the moving panel 9, that is, the heat exchanger 10a.
It can be connected to the drive mechanism case 65 arranged in the space 56 formed in the upper part by a simple structure. Therefore, it is not necessary to provide the driving mechanism case 65a adjacent to the moving panel 9, so that the driving mechanism case 65a is installed in the heat exchanger 10.
Since the moving path Z of the moving panel 9 can be provided by inclining to the upper rear by arranging the moving panel 9 rearward by utilizing the inclination of a, it is possible to reduce the size increase of the device due to the disposition in the vicinity of the moving panel 9. be able to.

On the other hand, as shown in FIG. 11, the connecting mechanism 60 has a rack 63 to which the moving panel 9 is attached.

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, and the lower end of the rack 63 contacts the stepped portion 47 of the decorative cover 3 to maintain the closed state. Next, in FIGS. 10 and 11, the operation signal is the terminal 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.
This will be described with reference to FIGS. 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 in a honeycomb shape with a pitch of 4 mm. According to the example of FIG. A, an aperture ratio of 54% (the ratio of the opening 77 to the unit area) is obtained, and according to the example 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, in this embodiment, the wall thickness of the cover 8 is set to 1 mm, which is smaller than the wall thickness of the slit-shaped suction portion formed by the horizontal and vertical bars on the conventional front panel. It reduces resistance, increases air flow, improves performance, and reduces noise. The depth of the conventional slit is 2.5 mm to 3 mm for the front panel in order to obtain strength and to make it difficult to see the inside.
It is formed larger. Further, by tapering the windward side of the opening 77, the air resistance can be further reduced and the wind flow can be improved. In this embodiment, the opening area of the first suction portion 7 is substantially 350c.
It is set to m2.

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.
With this, it is possible to increase the strength, and since the space 79 is formed between the filter 11 and the filter 11, the indoor air that has passed through the cover 8 can be evenly 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 independently cleaned (washed). Further, since the cover 8 has a thin plate-like punching shape, dust is unlikely to adhere, and the cleanliness seen from the outside can be improved.

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 air flow 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. Note that 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 the fan motor 18, the stepping motor 64 of the shutter mechanism section 31, and the stepping motors 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. During the preliminary operation, since the moving panel 9 is closed, the heat exchanger 10 can be placed in a closed space, so that the speed of warming or cooling the heat exchanger can be shortened. The rise time can be shortened during heating, and during cooling
It is possible to prevent the unpleasant odor generated due to the heat exchanger 10 not being cooled sufficiently from being blown out. Next, when the microcomputer 251 starts the preliminary operation and the operation preparation is completed, the stepping motor 24 and the stepping motor 64 are
Send an operation signal to. 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 up to a predetermined position shown in FIG. 10 (20
6). In step 206, the wind direction plates 6a and 6b and the moving panel 9 are simultaneously operated, and the completion of the operation is detected by the switch 252. Next, the microcomputer 251 operates the fan motor 18 (207) and the compressor (208) to start normal operation (209). Microcomputer 251
Determines the operation stop by the operation stop instruction from the remote controller or the set operation mode such as the timer (2
10), stop the compressor and fan motor 18 (211)
The stepping motor 24 and the stepping motor 64
An operating signal to operate the wind direction plates 6a and 6b and the moving panel 9 to the original closed state at the same time (21
2) The operation display lamp is turned off to bring the operation into a stopped state (213). It should be noted that the microcomputer 251 may blink the display unit 14 in correspondence with the operation speed during the operation of the stepping motor 64, that is, in order to indicate that the moving panel 9 is moving.

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. However, the moving panel 9 may be continuously operated after the wind direction plates 6a and 6b, or may be operated after a certain 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 light wind operation, the moving panel 9 is closed, and indoor air is sucked in from the second suction section 12 and the third suction section 13. In 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 and detached, thereby improving 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, the filter 11, the moving panel 9, the display unit 14, and the light receiving unit 15 are arranged on the decorative 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 that exposes 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 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. 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.

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 is 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

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 a 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 difference in lightness 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 that is hard to see, and by arranging the blowing portion 5 provided with the wind direction plates 6a and 6b on the large curved surface 34 that is lower, 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, dust can not be accumulated on the grill as in the conventional case and the cleaning performance can be improved, and the rising time of cooling and heating can be shortened.

Further, by adopting the heat exchanger 10 having a multi-stage bending structure that extends around the blower fan 16, the heat transfer area can be increased without changing the size of the indoor unit 1. The heat exchange rate can be improved to improve the driving ability. For example, according to this embodiment, it is possible to increase the size by 1.4 times as compared with the conventional example having a similar main body size which does not adopt the heat exchanger 10 having the multi-folded structure, and the same refrigerant. 4 in quantity
The heat exchange rate of 0% can be improved. Further, since the third suction portion 13 can be provided on the upper surface by adopting the same heat exchange 10, the substantial opening area of the upper opening portions 12a, 13a which are difficult to see in the installed state is increased to increase the ventilation amount. , The performance can be improved. For example, in this embodiment, it is possible to obtain an opening area (341 cm 2) which is 1.4 times larger than that of the conventional example. Further, by making the first suction portion 7 into a punching shape, the size of the suction portion occupying the front surface is reduced while the substantial opening area is increased and the ventilation resistance is reduced to increase the ventilation amount. The performance can be improved. For example, in the present embodiment, it is possible to realize an opening area of 350 cm 2 which is 1.2 times larger than the conventional example in the honeycomb-shaped numerical value as compared with the conventional example of the same main body having the slit-shaped suction portion. . Then, the first, second, and third suction sections 7, 12,
By adopting 13 to obtain a large opening area as a whole, there is an effect that the amount of ventilation can be increased and the performance of cooling and heating can be greatly improved. For example, as a whole, the amount of ventilation is 3 by obtaining an opening area 1.3 times larger than the conventional example of the same level.
It can be increased by 0%. 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, since the front panel 4 is not provided with slits, it can be easily cleaned by simply wiping it and can be washed with a circle. Further, it is possible to reduce vibrations and noises caused by the movement of the moving panel 9, as well as obstacles.

The suction part 138 is composed of an opening 58 formed in the front panel 4 and a punching cover 8 which is detachably attached to the opening 58 from the inside. The cover 8 has a tray shape in which a reinforcing rib 78 is formed on the inner periphery and a fixing rib 78a protruding outward is formed on the periphery of the end portion of the reinforcing rib 78. Further, the front surface of the cover 8 is formed with a large curved surface 35 continuous with the front panel 4, and the size (thickness) of the reinforcing rib 78 so that the large curved surface 35 is flush and continuous with the front surface of the front panel 4. Is prescribed. A large opening area is obtained by arranging a plurality of small regular hexagonal openings 77 shown in FIG. B in a honeycomb shape on the front surface of the cover 8. The cover 8 is formed by resin molding with a thickness (1.5 mm) smaller than the thickness of the front panel 4 (2.5 mm to 3 mm), and the opening 77 is formed by punching the front surface of the molded product. ing. And cover 8
Is inserted into the opening 58 from the inside of the front panel 4, and the fixing ribs 78a are detachably fixed by attaching ribs and attaching screws (not shown) formed inside the front panel 4. The second suction portion 139 is formed on the front portion of the upper surface and has the same structure and size as the third suction portion 13 described in the first embodiment. In addition, in this embodiment, the width of the first suction portion 138 is 738 mm and the height is 85 mm, the parallel line width of the regular hexagonal opening 77 is 3 mm, and the pitch of the opening 77 is 4 mm. 64% (ratio of multiple openings 77 per unit area)
I'm trying to get

According to this embodiment, the first suction portion 138
The indoor air sucked from the second suction section 139 can be blown out from the blowing section 5 into cold air or warm air by the heat exchanger 137. At this time, by making the first suction portion 138 a honeycomb-shaped punching shape, it is possible to improve the aperture ratio and reduce the ventilation resistance by reducing the wall thickness of the cover 8. Generally, in the conventional example including the suction portion formed of the horizontal rails, the wall thickness of the resin-molded front panel 4 is set to about 2.5 mm to 3 mm, and the wall pressure of the horizontal rail is set in consideration of the strength. Since it is molded to be thicker than the above wall pressure,
Passing through the air passages increased ventilation resistance, which hindered the improvement of air conditioning capacity.

In this embodiment, since the first suction portion 138 is covered with the punching thin cover 8, the length of the air passing through the opening 77 can be shortened and the ventilation resistance can be reduced. You can In addition, in this embodiment, the problem of strength caused by thinning the meat pressure is addressed by the cover 8
This is solved by providing a reinforcing rib 78 around the periphery of the cover, and the front surface of the cover 8 is formed with a large curved surface 35 to increase the strength. When the cover 8 is made larger than that of this embodiment, the inner wall of the cover 8 may be appropriately provided with a reinforcing rib.

Further, in this embodiment, the thickness of the opening 77 is set to 1.5 mm in consideration of the workability in punching. However, in the same processing, the thickness is in the range of 1 mm to 2 mm. If so, the same effect can be obtained. The cover 8 may be made of a metal material if the above-mentioned reinforcing means is applied. As described above, according to the present embodiment, the punching-shaped cover 8 (net) is provided on the first suction portion 138 arranged on the front side, so that the design of the first suction portion 138 is not impaired. The opening ratio of the first suction portion 138 can be improved, and the ventilation resistance can be reduced to improve the driving ability. Moreover, if the heat exchanger 137, which is cheap in price, is combined as in this embodiment, it is possible to reduce the overall manufacturing cost and obtain the above effects.

Further, in this embodiment, since the cover 8 can be attached to and detached from the front panel 4, the cover 8 which is conspicuously contaminated during cleaning can be separated from the front panel 4 to form a small part. It can be cleaned without taking it.

Although the heat exchanger 137 having a straight side surface is adopted in the above-mentioned embodiment, the heat exchanger 10 of the first embodiment is adopted and the same second and third heat exchangers are provided on the upper surface. Suction section 1
By providing 2 and 13, the ventilation capacity can be further increased and the driving ability can be improved without impairing the design in the installed state. Further, the second and third suction portions 12 or the second suction portion 139 may be punched like the cover 8.

In the figure, the indoor unit 140 of this embodiment shows the first suction part 1 having a plurality of openings 77 arranged in a honeycomb shape.
41 is large, and the first suction part 141 is integrally formed with the front panel 142, which is different from the indoor unit 136 of the above-described embodiment. The opening 77 has a wall thickness other than the first suction part 141 (2.5 mm to 3 m).
By forming it with a thickness of 1.5 mm, which is thinner than m), air resistance is reduced while solving the problem of resin flow during molding.

Further, in order to have strength, in this embodiment, as shown by the dotted line in FIG. 55 b, the zigzag reinforcing rib 143 is provided on the first suction part 141 while avoiding the opening 77.
The reinforcing ribs 143 can be seen in the installed state (front) so as not to impair the design by being properly provided inside. Further, in FIG. 56, the first suction portion 14 is shown in the drawing.
1 is indicated by diagonal lines, this is the first suction portion 14
FIG. 55B shows the range of FIG.
It is formed in the honeycomb shape shown in. For this reason, the first suction portion 141 is formed so as to melt into the front panel 142, so that it is possible to reduce the impression of the opening portion of the first suction portion 141 and improve the appearance design.

In the embodiment shown in FIGS. 53 to 56,
The square or regular hexagonal openings 77 are arranged regularly in a lattice or honeycomb shape, but the same effect can be obtained with other shapes,
For example, the opening 77 having a rhombus, a circle, a rectangle, a flat hexagon, an ellipse, or the like can be obtained. However, the regular hexagonal opening 77 has the highest aperture ratio, squares and diamonds are easy to manufacture, and other shapes have the effect of improving interior and decorativeness. Also, these openings 77 are 3 mm to 7 m.
By setting the size such that the elements can be arranged at a pitch of m, it is possible to make the inside less visible and improve the design, while obtaining the aperture ratio.

Furthermore, by arranging these openings 77 substantially uniformly in the vertical and horizontal directions, the opening areas can be optimized and the strength can be optimized, but even if they are arranged regularly. Good. For example, the central portion may be a large opening 77 in one direction (both sides) or four directions (surroundings).
As you go to, gradually make a small opening 77,
By arranging the plurality of openings 77 as one group and arranging the groups with regularity, it is possible to increase the aperture ratio and provide the entire strength while enhancing the decorativeness as a pattern. Further, if the aperture ratio is in the range of 50% to 70%, it is possible to make the interior less visible and improve the design. Furthermore, if the upper limit of the opening ratio is set to 80%, it is possible to protect the filter 11 while maintaining the decorativeness of the opening 77, but in this case, the reinforcing rib 143 that supports the opening 77 from the inside is provided. It is preferable to provide it so as to enhance the overall steel property.

Further, by forming the upper surface with the curved surface 33, it is possible to make the second suction portion 12 inconspicuous in the installed state and to suck the indoor air efficiently from the upper front side. On the other hand, since the lower surface is formed by the curved surface 34, the “surface” that is easy to adapt to the installation environment is utilized, and the blowing portion 5
05 can be given a tilt. Further, in the indoor unit 1, the front panel 504 has a flat shape with a uniform thickness when viewed from the outside, and the groove portion 36 is formed in a divided portion with the decorative cover 503.
And the decorative cover 503 fit together well, and accent lines are formed on the large curved surfaces 33 and 34 with continuous roundness to reduce the depth feeling and further improve the compactness.

In the front view shown in FIG. 59, in the indoor unit 501, the four corners of the front surface are formed with large radius 538a, and the four corners of the groove 36 and the large curved surface 35 are similar to the radius 538b of the large radius 538. 538
c and both side surfaces that are continuous with this radius 538 are slightly arcuate surfaces that are narrowed inward and have a large convex center, thereby forming a compact and rounded appearance shape with improved internal real phase efficiency. . In this embodiment, the large radius 538a is set to R18 mm.

00mm, R700mm on both sides, R5 on both ends
It is set to 0 mm.

The second suction portion 12 formed on the upper surface of the decorative cover 503 has a grill shape having a plurality of horizontal crosspieces 42 and a vertical crosspiece 43 for reinforcement, which are sparsely arranged, and has a wide width around the periphery. By leaving the casing surface, it is made inconspicuous while obtaining a large aperture ratio (a ratio of a substantial aperture per unit area). In particular, since the second suction portion 12 is made inconspicuous by the curved surface 33, the designability is not deteriorated even if the opening ratio is large. In addition, in this embodiment, the opening ratio of the second suction portion 12 is set to about 80%. Further, in this embodiment, the width of the second suction portion 12 is set to 690 mm and the depth thereof is set to 50 mm. Further, five horizontal rails 42 are provided at substantially equal intervals.

Further, in this embodiment, as in the first embodiment, since the fan motor 18, the electrical equipment box 25, etc. are provided on the right side of the indoor unit 501, the right side of the second suction section 12 is provided with the above-mentioned components. A partition plate 44 for concealing the internal structure is formed. Therefore, in this embodiment, a substantial opening portion 12a for suction having a lateral width of 635 mm is provided on the left side of the second suction portion 12. In addition, the vertical bar 43
Is provided at a position deeper than the horizontal rail 42, and the opening 1

Then, the decorative cover 503 is configured to include the main mechanical parts such as the blower fan 16 and the heat exchanger 10 therein.
Is attached to the upper part of the back cabinet 502, and the lower part is attached to the back cabinet 502 via screws.

Also, the filter 11 has a decorative cover 503.
"V-shaped" through the guide rails on both sides of the
The heat exchanger 10 is detachably attached to its front surface. Then, the front panel 504 is provided on the front surface of the makeup cover 503, for example, through a mechanism similar to that of FIG.
It is attached such that the lower end can be opened with the upper end as the rotation axis.

By adopting such a structure, the room air sucked from the first suction section 507 and the second suction section 12 is turned into warm air or cold air through the filter 11, the heat exchanger 10 and the blower fan 16. The heat is exchanged and the air is blown out from the blowing portion 505.

At this time, since the heat exchanger 10 is formed in a "dogleg" shape, the first suction portion 507 is efficiently connected to the lower heat exchanger, and the second suction portion 12 is efficiently connected to the upper heat exchanger. Can inhale well. Further, the filter 11 is the heat exchanger 10.
Since a space with a large depth is formed between the first suction portion 507 and the second suction portion 12, the air sucked through this space is rectified. , The first suction part 507 or the second suction part 1
Even if a part of 2 is blocked, indoor air can be sucked in from the other openings and heat can be reasonably exchanged from the heat exchanger 10 in the blocked part. Further, since the space between the first suction portion 507 and the filter 11 is widened, it is difficult to see the inside from the outside through the plurality of openings 77 of the first suction portion 507, which is good in design. .

Next, the first suction portion 507 integrally formed with the front panel 204 will be described in detail with reference to FIGS. 61 to 64.

With this structure, at the time of molding, it is possible to improve the flow of molten resin from the thick wall portion to the thin wall portion, so that the occurrence of welds and sink marks due to staircase shapes or ribs can be reduced. You can Therefore, the molding accuracy can be improved even with a resin material such as PP resin which is inexpensive and has good recyclability but is apt to cause welds and sink marks. Further, since the stress relating to the thin portion can be evenly dispersed through the inclined surface 509 which is gradually thinned in terms of strength, the strength can also be improved.

In FIG. 62, in this embodiment, the opening 7
7 is formed into a hexagonal shape whose corners are rounded. The hexagonal opening 77 has a parallel line width set to 3.3 mm, and a 1 mm honeycomb frame is left between the hexagonal opening 77 and another adjacent opening 77. The portion 209 is formed in a honeycomb shape in the range of 735.3 mm in width and 89.4 mm in height.

Further, in this embodiment, the cross-sectional shape of the opening 77 is, as shown in FIG. 62 (c), the windward side (the upper side in the drawing) outside the casing and the inside of the casing. The leeward side (lower part in the drawing) of the opening end is rounded, for example,
In this embodiment, R is 0.3 mm. According to the shape of the opening 77, the air resistance at the time of taking the indoor air into the opening 77 is small, and the turbulent airflow when being drawn into the housing from the opening 77 can be reduced, thereby improving the overall suction efficiency. Can be improved.

This molding method will be described with reference to FIG. In the figure, 601 indicates a concave shape that forms the outside of the front panel 504, 602 indicates a convex shape that forms the inside of the front panel 504, and 603 indicates a honeycomb-shaped frame body.

FIG. 13A shows a molding method adopted in this embodiment, in which the concave mold 601 and the convex mold 602 have openings 77 respectively.
To form the projections 601a and 602a that form the
By injecting a resin material into the space formed by 01a and 602a, the front panel 504 including the honeycomb frame 603 can be formed. Further, in the embodiment shown in FIG. 6B, the convex portion 601b forming the opening 77 has a concave shape 6
No. 01 is formed.

According to the molding method shown in (a), the concave mold 601 is used.
Since the combination of the convex mold 602 and the convex mold 602 is provided between the honeycomb-shaped frame bodies 603, when the mold is aged, the concave mold 601 and the convex mold 6 are
Since it is possible to make the occurrence of burrs that occur during the period of 02 to block the opening 77 less than in the case of (b), it is possible to reduce post-processing after molding such as removing burrs. Further, in the embodiment shown in FIG. 7A, the outer and inner ends of the opening 77 can be easily formed into a round shape or a surface cut shape. On the other hand, in the embodiment of FIG. (B), the windward end of the opening 77 can be rounded, and burrs that may occur when the mold is aged are a design problem. Since it is generated only inside the case where it does not occur, post-processing after molding can be done by end face processing on the inside, and the unit price of the mold can be reduced.

Next, FIG. 64 illustrates the strength of the first suction portion 507 of this embodiment in comparison with the conventional example.
(A) figure shows the 1st suction part 507 of this Example, (b) figure has shown the suction part of the conventional grill structure.

In FIG. (A), in the present embodiment, for example, when pressure is applied from the outside to the point Z1 of the first suction part 507, the applied stress is, as shown in the figure, a honeycomb-like shape. The step portion 50 is spread evenly outward by the frame body.
8 supported by the whole. On the other hand, in the conventional grill structure shown in (b), the stress applied to the point Z2 is
For example, the stress applied to the point Z2 of the horizontal rail 610 is due to the mounting portion 611 of the horizontal rail 610 supporting the horizontal rail 610, and the stress of the horizontal rail 6.
Stress is concentrated on the vertical ribs 612 that support 10 and the mounting portions 613 of the vertical ribs 612. Therefore, in the conventional example, in order to have a structure that can withstand this partially concentrated stress, the attachment portions 611 and 613, that is, the horizontal bars 61.
0 and the vertical ribs 612 have a structure in which the entire attachment portion has strength. Further, as a matter of course, the horizontal rails 610 and the vertical ribs 612 are also made thick enough to withstand the stress. Therefore, in the conventional example, the horizontal crossbar 610 and the vertical rib 612 are thick, and the mounting portions 611 and 61 thereof are also thickened.
Since No. 3 also needs to be made to be robust, there is a problem of sinkage due to an increase in ventilation resistance due to an increase in wall thickness, or an increase in wall thickness.

In this respect, in the present embodiment, the force applied to the point Z1 is dispersed to the periphery by the honeycomb structure, and the dispersed stress is absorbed by the step portion 508, so that the flat portion 509 is made thin. Can also maintain strength.
Therefore, it is possible to reduce the ventilation resistance by reducing the wall thickness of the first suction portion 507.

Further, for example, when the indoor air sucked from the first suction section 507 has the same air volume, the area of the first suction section 507 can be made smaller than that of the conventional example. In the present embodiment, the height dimension of the first suction portion 507 can be made 30% smaller than that of the conventional horizontal rail grill. As a result, it is possible to increase the relative strength of the first suction portion 507, which is considered to have the weakest strength in the front panel 504. Further, as a result, by reducing the area of the first suction portion 507, it is possible to reduce the opening occupying the front surface and increase the planar portion, which can be improved in design, and at the same time, from the first suction portion 507. The inside can be made difficult to see.

In addition, the curved shape of the flat surface portion 509 and the inclined surface 539 in which the thickness of the step portion 508 is gradually reduced can further improve the above effect. In this embodiment, the front panel 504 is formed of HIPS resin. However, by adopting the above structure, for example, even PP resin, which is inexpensive and has good recyclability, reduces sink marks and welds and further maintains strength. Can be adopted while.

Although the step portion 508 is formed on the front surface side of the front panel 504 in this embodiment, the front surface of the front panel 504 is formed into a uniform curved surface with the large curved surface 35 and is formed inside the front panel 504. By doing so, it is possible to achieve various developments in terms of design, while obtaining the same strength and manufacturing effects as those of the above-described embodiment.

In order to obtain more strength with the structure of the first suction portion 507, the first suction portion 507 is divided in the left-right direction (longitudinal direction), that is, the plurality of openings 77 are arranged in the left-right direction. Reinforcing ribs are provided on the back surface side of the divided portion in which the opening portion 77 is not formed, or a plurality of flat surface portions 509 are formed in the left-right direction via the step portion 508, A plurality of openings 77 in the plane
By providing, the strength can be further improved without impairing the designability and moldability.

According to the above-described embodiment, it is possible to form the cover with a small wall thickness while improving the design while making the inside difficult to see due to the regular arrangement and the ratio of the plurality of openings per unit area. The performance can be improved by reducing the ventilation resistance to obtain the air volume.

Further, since the cover which can reduce the ventilation resistance and obtain the air volume can be made more steel by the regular arrangement of the openings and the reinforcing portions, the performance can be improved while obtaining the strength.

Further, since the cover capable of reducing the ventilation resistance and obtaining the air volume can be easily separated from the housing together with the front panel, the cover capable of improving the performance can be easily removed and cleaned.

Further, since the cover capable of reducing the ventilation resistance and obtaining the air volume can be easily separated from the housing, the cleaning property of the cover can be improved.

Further, the cover, which can reduce the ventilation resistance and obtain the air volume, can be easily separated from the housing together with the filter, and can be easily attached and detached to improve the cleaning property.

Further, by forming the suction portion formed on the front surface of the casing to be thinner than the thickness of the front surface of the other casing, it is possible to reduce the ventilation resistance and obtain the air volume, so that the structure is simple. It is possible to enhance the design and improve the performance while making it difficult to see the inside.
