Description

  The present invention relates to a ceiling-embedded air conditioner, and more particularly, to a configuration of a decorative panel of a ceiling-embedded air conditioner.

  A ceiling-embedded air conditioner is generally composed of a main body that is inserted from the ceiling opening and attached to the back of the ceiling, and a decorative panel that is fitted in the ceiling opening so as to cover the ceiling opening and attached to the lower surface of the main body. Yes. Moreover, as a ceiling-embedded air conditioner, a four-way type or a two-way type is often used. In the four-way type, for example, as described in Patent Document 1, the main body has a box shape having a substantially square shape in plan view, and a blower, a heat exchanger, and the like are accommodated therein. In addition, the decorative panel has a substantially square shape in plan view, and is formed so that the projecting dimension from the ceiling is small, an indoor outlet is formed along the edge of the four sides, and the indoor suction is formed in the central portion. Mouth is formed. A lattice-shaped non-opening / closing grill structure is formed in the indoor suction port to form an air passage hole, and a wind direction plate for changing the wind direction is rotatably attached to the indoor air outlet. ing.

In the case of the two-way outlet type, for example, as described in Non-Patent Document 1 as a two-way double flow type, two indoor outlets are provided along the longitudinal edges of two opposing sides of the decorative panel.

  However, in the four-direction blowout type ceiling-mounted air conditioner of Patent Document 1, the indoor suction port has a non-opening / closing type grill structure and is treated decoratively, and therefore the presence of the indoor suction port is conspicuous and the ceiling There was a problem of lack of unity. Moreover, in order to ensure the real suction area which deducted the area which the structural member which comprises a grill structure subtracts, the indoor suction inlet became large and the dimension between an indoor suction inlet and an indoor blower outlet became small. For this reason, there existed a problem that the short circuit between an indoor blower outlet and an indoor suction opening tends to arise. In addition, in the two-way blowing type (two-way double flow type) ceiling-embedded air conditioner of Non-Patent Document 1, the center portion of the decorative panel between the indoor air inlets is flat to provide a sense of unity with the ceiling. However, the short circuit of the blown air has been a problem because the indoor suction port is formed adjacent to the indoor blowout port.

  The present invention has been made paying attention to such problems existing in the prior art. The purpose is to improve the sense of unity with the ceiling by using a simple flat air inlet, and a ceiling-embedded type that reduces the short circuit by forming a flat isolation surface between the air outlet and the air inlet. It is to provide an air conditioner.

  The ceiling-embedded air conditioner according to the present invention that solves the above problems includes a main body installed above the ceiling opening, a decorative panel attached to the lower surface of the main body so as to cover the ceiling opening, and a decorative panel. In the decorative panel, at least a pair of indoor air outlets formed along two opposing edges, and a flat isolation surface between the indoor air outlets, the central portion between the indoor air outlets is formed. And an open / close lid having a flat surface provided at the indoor intake port, and a drive device for driving the open / close lid. The opening / closing lid is driven by the driving device so as to close the indoor suction port with a flat surface when the operation is stopped and to move upward to open the indoor suction port during the operation.

  According to the air conditioner according to the present invention configured as described above, since a flat isolation surface is formed between the indoor outlet and the indoor inlet in the decorative panel, the indoor outlet and the indoor inlet The short circuit between is reduced. In particular, in this air conditioner, since the non-opening / closing type grill structure is not formed at the indoor suction port, the opening area is the same as compared with the conventional indoor suction port having the non-opening / closing type grill structure. In addition, the size of the indoor suction port can be reduced. Therefore, since the indoor suction port can be reduced, the isolation surface between the indoor air outlet and the indoor air inlet can be increased, and a short circuit between the indoor air outlet and the indoor air inlet can be further increased. It can be effectively reduced. In addition, when the operation is stopped, the indoor suction port and the flat isolation surface formed between the indoor air outlet and the indoor suction port are continuous to form a simple flat surface with a large area. Can improve the sense of unity. In addition, even during operation, since the opening / closing lid moves in the machine so as not to protrude outside the machine, a simple flat feeling is maintained.

  Further, in the air conditioner configured as described above, the opening / closing lid is formed of a single flat panel having a flat surface portion, and is flat when the operation is stopped. It is good also as a structure driven by the said drive device so that an indoor suction inlet may be closed by a surface part and a flat panel may be moved upwards in a horizontal state and open | released an indoor suction opening at the time of a driving | operation. Since the decorative panel of the air conditioner configured in this way has a simple flat structure in which the gap forming the contour appears linearly around the indoor suction port in the closed state when the operation is stopped. , Can improve the sense of unity with the ceiling.

  Further, instead of the above configuration, the open / close lid is composed of two flat panels of the same quadrilateral having a flat surface portion, and is flat when the end faces of both flat panels are abutted when the operation is stopped. By closing the indoor suction port at the surface, and during operation, the drive device is configured to open the indoor suction port in a V-shaped state by moving the opposite end surfaces across the abutted end surface upward. It may be configured to be driven. The decorative panel of the air conditioner configured in this way is a simple flat so that when the operation is stopped, the gap forming the contour around the indoor suction port and the gap between the end faces to be seen look straight. Since it has a structure, it is possible to improve the sense of unity with the ceiling and to make the mechanical structural member in the machine less noticeable from the indoor suction port during operation, so that the design during operation can be improved.

  In the air conditioner having the above-described configuration, a sound absorbing material may be attached to the upper surface of the flat panel constituting the opening / closing lid. If it does in this way, since the operation sound of the air blower is absorbed by the sound absorbing material of the flat panel during operation, the operation sound of the air conditioner is reduced. Incidentally, in a conventional four-way air conditioner, an indoor suction port having a non-opening / closing type grill structure is arranged immediately below the blower, so that the operation sound of the blower is directly indoors from the opening of the grill structure. It was propagated and the driving noise was loud.

  Further, in the air conditioner configured as described above, a wind direction plate provided at an indoor outlet and a rotation device that rotates the wind direction plate are further provided, and the wind direction plate has a flat surface when the operation is stopped. The interior air outlet may be closed by the unit, and the structure may be configured to be rotated by the rotating device so as to rotate during operation and guide the blown air in a predetermined direction. If comprised in this way, since the whole decorative panel is formed in a plane part at the time of a driving | operation stop, a sense of unity with a ceiling can be improved more as a simple flat structure.

  According to the air conditioner of the present invention, it is possible to improve the sense of unity with the ceiling as a simple flat structure, and it is possible to suppress a short circuit between the indoor outlet and the indoor inlet.

(Embodiment 1)
Hereinafter, the air conditioner according to the present embodiment will be described with reference to FIGS.
Here, FIG. 1 is an external perspective view of the two-way blowing-type ceiling-embedded air conditioner according to Embodiment 1 of the present invention when operation is stopped. FIG. 2 is an external perspective view of the air conditioner during operation. FIG. 3 is a side cross-sectional view (A-A cross-sectional view in FIG. 1) when the air conditioner is stopped. FIG. 4 is a side sectional view (BB sectional view of FIG. 2) during operation of the air conditioner. FIG. 5 is a perspective view of the opening / closing lid driving device.

  The air conditioner according to the present invention is a two-way blowing-type ceiling-embedded air conditioner as shown in FIGS. 1 to 4, and includes a main body 2 installed above the ceiling opening 1, and a ceiling opening. And a decorative panel 3 attached to the lower surface of the main body 2 so as to cover the ceiling opening 1.

  As shown in FIGS. 3 and 4, the main body 2 has a rectangular box shape in plan view, and is inserted into the ceiling from the ceiling opening 1 formed in the ceiling 4 of the air conditioning target room R, and is attached to the ceiling. It has been. A turbo fan 5 as a blower (indoor fan) is disposed in the central portion in the short side direction in the main body 2 (illustration is omitted for this arrangement), and on both sides in the short side direction with the turbo fan 5 interposed therebetween, An indoor heat exchanger 6 extending in the longitudinal direction is arranged. One or a plurality of turbofans 5 are used corresponding to the capacity of the air conditioner, but in the case of a plurality of units, they are arranged in the longitudinal direction of the main body 2 (this embodiment has two units). Is the case). Further, as shown in FIGS. 3 and 4, the turbo fan 5 sucks air in the air-conditioning target room R into the main body 2 through the indoor suction port 11 provided in the center portion in the short side direction of the decorative panel 3. The bell mouth 7 that constitutes the suction port of the turbofan 5 is attached to the lower side so that the rotary shaft is in the vertical direction so as to discharge in the outer peripheral direction. An air filter 8 is attached below the bell mouth 7 of the turbofan 5.

  As shown in FIGS. 3 and 4, the decorative panel 3 has a flat shape with a rectangular shape in plan view, and has a small rising piece 3 a at the edge as an end surface treatment on the upper surface side, and further has a ceiling opening 1. The small upright piece 3b for fitting in is provided. Moreover, as shown in FIG.1 and FIG.2, a pair of long hole-shaped indoor blower outlet 12 is formed in the decorative panel 3 along the edge part which extends in the opposing longitudinal direction. Moreover, the indoor suction inlet 11 is formed in the center part of a short side direction by interposing the flat isolation surface 3c between this indoor blower outlet 12. FIG. As shown in FIGS. 3 and 4, the indoor suction port 11 is a single quadrilateral flat panel having a flat surface portion on the lower surface and a small rising piece 13 a as an end surface treatment on the periphery. An opening / closing lid 13 is provided. The open / close lid 13 is loosely fitted into the indoor suction port 11 so that a flat surface portion is flush with a flat surface portion such as the surrounding isolation surface 3c when the operation is stopped, and the air filter 8 It is configured to move while keeping the horizontal state to a position slightly below. An appropriate sound absorbing material (not shown) is attached to the upper surface of the flat panel constituting the open / close lid 13.

  Next, a driving device for driving the opening / closing lid 13 will be described with reference to FIGS. As shown in these drawings, a drive motor 14 is attached to the upper surface of the opening / closing lid 13 with the horizontal direction in FIGS. 3 and 4 as the axial direction. The drive motor 14 is formed as a double-axis motor, and pinions 15 are attached to both ends thereof. A pinion 15 is directly attached to one motor shaft 14a, a shaft 14c is added to the other motor shaft 14b via a joint 14d, and a pinion 15 is attached to the tip thereof. These pinions 15 are engaged with a rack 18 suspended from the upper surface of the decorative panel 3 and are attached so as to be sandwiched between side surfaces of a U-shaped frame member 15a. The frame member 15 a ensures the engagement between the pinion 15 and the rack 18, penetrates the motor shafts 14 a and 14 c on the side surface of the pinion 15, and surrounds the back surface of the rack 18 from the side surface of the pinion 15. It is formed in a U shape in plan view. With this configuration, the frame member 15a moves up and down with respect to the rack 18 together with the motor shafts 14a and 14c as the pinion 15 rotates, thereby stabilizing the meshing state of the pinion 15 and the rack 18. It is configured to let you. The motor shafts 14a, 14b, and 14c are supported by bearings 17 as appropriate. Further, as shown in FIG. 5, a support plate 19 is suspended from each central portion of both edge portions parallel to the motor shafts 14a, 14b, 14c, and the motor shafts 14a, 14b, The protrusion part 20 which protrudes in the direction orthogonal to 14c is attached. The protrusion 20 is formed with a U-shaped groove 20 a that sandwiches a cylindrical rod 21 that is suspended from the side of the indoor suction port 11.

  Since the drive device for driving the opening / closing lid 13 is configured in this way, the pinion 15 is rotated by the rotation of the motor shafts 14a, 14b, and 14c when the drive motor 14 is driven as the operation starts. As the pinion 15 moves upward on the rack 18 as it rotates, the open / close lid 13 is moved upward. At this time, since the U-shaped groove 20a sandwiches the cylindrical rod 21, the opening / closing lid 13 is prevented from rotating and tilting and is moved to a predetermined position below the air filter 8 while maintaining a horizontal state. To do. Therefore, the cylindrical bar 21 and the protrusion 20 function as a guide for smoothly moving the opening / closing lid 13 up and down.

  On the other hand, each indoor outlet 12 is provided with a wind direction plate 25 and a rotation device such as a motor for rotating the wind direction plate 25. When the operation is stopped, the wind direction plate 25 closes the indoor air outlet 12 with a flat surface portion as shown in FIG. 3, and at the time of operation, the air flow blown out from the indoor air outlet 12 as shown in FIG. It guides in the direction of selection. The shape of the wind direction plate 25 may be an appropriate shape such as a flat plate shape or an airfoil shape as long as it has such a function, but in this embodiment, it is a flat plate shape. Each wind direction plate 25 supports the rotation shaft 26 of the wind direction plate 25 at both ends in the longitudinal direction of the indoor air outlet 12. Further, as a rotating device for rotating each wind direction plate 25, a small motor is attached to a side portion of each indoor outlet 12 (not shown), and is connected to one end of the rotation shaft 26 of each wind direction plate 25. ing.

The operation of the air conditioner according to the present embodiment will be described.
When the operation of the air conditioner is stopped, since the turbo fan 5 is not operated, the indoor outlet 12 is closed by the wind direction plate 25 as shown in FIGS. At this time, the wind direction plate 25 is moved so that the flat surface portion is flush with the flat portion such as the isolation surface 3c around the indoor outlet 12. The open / close lid 13 of the indoor suction port 11 is also closed. At this time, the open / close lid 13 is lowered so that the flat surface portion is flush with the flat portion such as the isolation surface 3 c around the indoor outlet 12, and is loosely fitted into the indoor suction port 11. Thus, when the operation is stopped, the interior outlet 12 and the interior suction port 11 are not opened but are formed on a flat surface, so the decorative panel 3 has a very simple flat structure.

  Next, during the operation of the air conditioner, the turbo fan 5 is operated, and a blowing operation is performed to ventilate the air as shown by arrows in FIGS. In addition, an outdoor unit (not shown) is operated, and the temperature of the indoor air is adjusted by the indoor heat exchanger 6. At this time, at the indoor outlet 12, the wind direction plate 25 is rotated to a desired position by driving a rotating device (not shown), and the blown airflow is blown out in the direction desired by the user. Further, in the indoor suction port 11, the opening / closing lid 13 is moved to a predetermined upper position, that is, a position slightly below the air filter 8 by rotating the pinion 15 on the rack 18 by driving the drive motor 14. . In addition, when the opening / closing lid 13 moves from the closed position (the state shown in FIG. 3) to the opened position (the state shown in FIG. 4), the opening / closing lid 13 is a side perpendicular to the side on which the pinion 15 is attached. Since the U-shaped groove 20a of the protrusion 20 is guided by the cylindrical rod 21, it can be smoothly moved without rotating or tilting.

  In such an operating state, when the operation of the air conditioner is stopped, the wind direction plate 25 of the indoor outlet 12 is rotated so as to return to the closed state by driving the rotating device. In addition, the open / close lid 13 of the indoor suction port 11 is also moved so as to return to the closed state by driving of the drive motor 14.

Since the air conditioner of Embodiment 1 is configured as described above, the following effects can be achieved.
(1) Since the flat isolation surface 3c is formed between the indoor air outlet 12 and the indoor air inlet 11 in the decorative panel 3, a short circuit between the indoor air outlet 12 and the indoor air inlet 11 is reduced. The

  (2) Since the non-opening / closing type grill structure is not formed in the indoor suction port 11, the indoor suction port 11 has the same opening area as compared with the conventional indoor suction port having the non-opening / closing type grill structure. Can be reduced in size. Therefore, the separation surface 3c between the indoor air outlet 12 and the indoor air inlet 11 can be increased by the amount that the indoor air inlet 11 can be reduced, and the space between the indoor air outlet 12 and the indoor air inlet 11 can be increased. The short circuit can be reduced more effectively.

  (3) When the operation is stopped, the indoor suction port 11 and the flat isolation surface 3c formed between the indoor air outlet 12 and the indoor suction port 11 are continuous to form a simple flat surface having a large area. Therefore, a sense of unity with the ceiling 4 can be improved.

  (4) The open / close lid 13 is formed from a single flat panel having a flat surface portion, and when the operation is stopped, the flat panel is horizontal and the indoor suction port 11 is closed by the flat surface portion. Therefore, only the outline is formed around the indoor suction port 11. Therefore, a sense of unity with the ceiling 4 can be further improved as an extremely simple flat structure.

  (5) Further, since the opening / closing lid 13 is configured to be moved upward in the machine when opened, the opening / closing lid 13 does not protrude below the decorative panel 3. For example, a method of lowering the decorative panel 3 as a configuration in which the opening / closing lid 13 is opened is conceivable. However, in this case, there is a problem that the appearance during driving deteriorates. In contrast, the present embodiment does not have such a problem.

  (6) Since the sound absorbing material (not shown) is attached to the upper surface of the flat panel constituting the open / close lid 13, the operating sound of the turbo fan 5 as the blower during operation is the sound absorbing material of the flat panel. Sound is absorbed. As a result, the operation sound of the air conditioner is reduced.

(Embodiment 2)
The opening / closing lid of the indoor suction port according to the present invention may be any one that opens the indoor suction port by moving it upward in the machine and closes the indoor suction port with a flat surface portion in a state of moving downward, An open / close lid and a driving device as shown in FIGS. FIG. 6 is an external perspective view of the two-way blowing-type ceiling-embedded air conditioner according to Embodiment 2 when operation is stopped. FIG. 7 is an external perspective view of the air conditioner during operation. FIG. 8 is a side cross-sectional view (CC cross-sectional view of FIG. 6) when the air conditioner is stopped. FIG. 9 is a side cross-sectional view (DD cross-sectional view of FIG. 7) during operation of the air conditioner. In these drawings, the same elements as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the second embodiment, the opening / closing lid 31 and the driving device are changed as compared with the first embodiment. The opening / closing lid 31 is a quadrilateral (rectangular) having the same shape obtained by dividing a rectangle having a flat surface portion into two. It consists of two flat panel 32 of these. Then, when the operation is stopped, the flat panel 32 is in a state where the end faces 32a are abutted with each other as shown in FIGS. The indoor suction port 11 is closed by a rectangular flat surface portion. In addition, during operation, the flat panel 32 moves the end surfaces 32a on both sides facing each other across the end surfaces 32a to be abutted to be deformed into a V shape to open the indoor suction port 11.

  An outline of the drive device for driving the opening / closing lid 31 is shown in FIGS. The two flat panels 32 having the same quadrilateral shape are pivotally supported so that both end portions of the end surfaces 32a to be abutted are rising pieces 3a of the indoor suction port 11 so as to be rotatable without moving up and down. (Note that this point is not shown). And the hole 8a is formed in the center part of the air filter 8 attached above the end surface 32a to face | match, and the indoor inlet 11 is crossed in the front-back direction in the paper surface of FIG.8 and FIG.9 below. A pier-like motor support member 33 is provided. A small motor 34 is attached to the upper surface of the central portion of the motor support member 33 so that the motor shaft 35 protrudes downward. The motor shaft 35 of the small motor 34 extends through the hole provided in the motor support member 33 described above to an upper position near the flat panel 32.

  A male screw is formed on the motor shaft 35 of the small motor 34. A cylindrical member 36 in which a female screw that is screwed into the male screw is formed is screwed into the motor shaft 35. The cylindrical member 36 is connected to both the flat panel 32 by an arm 37. The arm 37 is rotatably connected to the cylindrical member 36 and the two flat panels 32.

  The opening / closing lid 31 is driven as follows by the drive device according to Embodiment 2 configured as described above. First, the operation stop will be described. As shown in FIG. 8, the motor shaft 35 is rotated by driving the small motor 34, and the cylindrical member 36 connected to the opening / closing lid 31 is moved downward by the arm 37. The cylindrical member 36 is moved downward until the arm 37 is substantially horizontal. As a result, the end faces 32a facing each other of the two flat panel panels 32 are abutted to each other to form a rectangular flat surface portion by the two rectangular flat panel panels 32. Closed. On the other hand, during operation, as shown in FIG. 9, by rotating the small motor 34 in the direction opposite to that during operation stop, the cylindrical member 36 is pulled upward, and the arm 37 is positioned obliquely accordingly. The central portions of both flat panel 32 are pulled up simultaneously. As a result, the two flat panels 32 are opened in a V-shape with the end face 32a at the lower position because the end face 32a to be abutted does not move.

  Since the air conditioner according to Embodiment 2 includes the opening / closing lid 31 and the driving device as described above, when the operation is stopped, a gap forming the contour around the indoor suction port 11 and an end face to be abutted with each other It becomes a simple flat structure in which the gap between the 32a looks straight. Therefore, although the gap line is increased by one as compared with the first embodiment, the flat structure is much simpler than the conventional one, and the sense of unity with the ceiling 4 can be improved. Moreover, since it becomes a V-shaped open state during operation, the mechanical structural member in the machine can be made less conspicuous from the indoor suction port 11 than in the case of Embodiment 1, and the air conditioner in operation can be The design can be improved.
