As shown in FIG. 1, a ceiling-embedded air conditioner 1 includes a main body 2 that is installed on the back of a ceiling and has an indoor side opening in a square cross section, and an external appearance that is provided on the indoor side of the main body 2 and exposed to the ceiling surface 3 Case 4 is provided. Further, in the main body 2 of the ceiling-embedded air conditioner 1, a blower fan 5 that sends air sucked from an inlet 12 (described later) of the main body 2 to an outlet 13 (described later) of the main body 2, and a main body A heat exchanger 6 that is installed downstream of the blower fan 5 and exchanges heat with the air sucked from the suction port 12, and a dust collection filter 7 that removes dust and dirt in the air sucked into the main body 2. And. The ceiling-embedded air conditioner 1 covers the opening of the main body 2 with a decorative panel 8 that is flat with the ceiling surface 3. The decorative panel 8 is moved up and down by the lifting device 9 according to the operating status of the blower fan 5.

As shown in FIG. 2, the main body 2 has a rectangular parallelepiped box shape, and is attached to the back of the ceiling so that the indoor side is open. The external case 4 is attached so as to surround the periphery of the opening 2 of the main body 2 when viewed from the indoor side. That is, the appearance case 4 has a square shape obtained by removing the central portion from the plate shape. Further, the outer case 4 is attached to be flat with the ceiling surface 3. Of course, the appearance case 4 does not have to be completely flat with respect to the ceiling surface, as long as it looks flat at first glance.

The blower fan 5 is provided at the center of the bottom of the box-shaped body 2 as shown in FIG. As the blower fan 5 rotates, indoor air is sucked in from the suction port 12 and blown out from the air outlet 13. The heat exchanger 6 is disposed between the blower fan 5 and the blower outlet 13, and exchanges heat with the air sucked from the suction port 12 by the operation of the blower fan 5. The dust collection filter 7 is disposed between the suction port 12 and the blower fan 5 on the back side of the decorative panel 8 when viewed from the indoor side, and is included in the air sucked from the suction port 12 by the operation of the blower fan 5. Plays the role of removing dust.

As shown in FIGS. 1 and 2, the decorative panel 8 is provided so as to fill the central portion of the square-shaped appearance case 4 and to cover the opening of the main body 2. The decorative panel 8 includes a square-shaped peripheral panel 10 and a square plate-shaped central panel 11 provided so as to fill the central portion of the peripheral panel 10. The central panel 11 covers the inlet 12, and the peripheral panel 10 covers the inlet 12 and the outlet 13. That is, the square-shaped peripheral panel 10 is disposed inside the square-shaped appearance case 4, and the rectangular plate-shaped central panel 11 is disposed further inside. The outer case 4, the peripheral panel 10, and the central panel 11 form a single plate, and these are attached flat to the ceiling surface 3 when viewed from the indoor side. Of course, the appearance case 4, the peripheral panel 10, and the center panel 11 may be flat as long as they are not flat with respect to the ceiling surface 3.

Subsequently, the arrangement of the wind direction vanes 14 will be described with reference to FIG. In addition, the arrow of FIG. 3 has shown the flow of the air, ie, an air path.

As shown in FIG. 3, the lifting device 9 of the ceiling-embedded air conditioner 1 according to the first embodiment lifts the peripheral panel 10 among the decorative panels 8. When the operation of the ceiling-embedded air conditioner 1 starts, the blower fan 5 starts rotating. Further, in parallel, the lifting device 9 moves the peripheral panel 10 to the indoor side. Thereby, indoor air conditioning is started.

When the peripheral panel 10 is moved indoors by the elevating device 9, a gap is formed between the peripheral panel 10 and the central panel 11, and this gap becomes the suction port 12 of the ceiling-embedded air conditioner 1. Similarly, when the peripheral panel 10 moves to the indoor side, a gap is formed between the peripheral panel 10 and the appearance case 4, and this gap becomes the air outlet 13 of the ceiling-embedded air conditioner 1. That is, when the ceiling-embedded air conditioner 1 is stopped, the appearance case 4, the peripheral panel 10, and the central panel 11 are arranged flat on the ceiling surface 3 with no gaps as shown in FIG. The air outlet 13 is not formed, and the suction port 12 and the air outlet 13 are formed by the peripheral panel 10 moving to the indoor side during operation. That is, one suction port 12 is formed in a square shape, and one outlet port 13 is also formed in a square shape.

When the operation of the ceiling-embedded air conditioner 1 starts, indoor air is sucked into the main body 2 from the suction port 12. The air sucked into the main body 2 passes through the dust collection filter 7, the blower fan 5, the heat exchanger 6, and the air is conditioned to be blown into the room through the outlet 13.

As shown in FIG. 3, the ceiling-embedded air conditioner 1 is further provided with a wind vane 14 on the inner wall surface side of the air outlet 13. By adjusting the angle of the wind direction vane 14, the air blowing direction blown into the room can be adjusted. Further, the wind direction vane 14 is disposed on the back surface of the decorative panel 8, particularly the peripheral panel 10. Furthermore, the end of the wind vane 14 is arranged so as to be inside the end of the decorative panel 8, particularly the peripheral panel 10.

As shown in FIGS. 1 and 3, the wind vane 14 is located on the back surface of the decorative panel 8, particularly the peripheral panel 10, both when the ceiling-embedded air conditioner 1 is stopped and operated. Not visible.

Further, the amount of movement of the peripheral panel 10 to the room side by the lifting device 9, that is, the amount of descent may be changed according to the blowing direction of the air supplied into the room. As shown in FIG. 4, for example, FIG. 4A shows a case where air is blown along the ceiling, and FIG. 4C shows a case where air is sent so that a person in the room feels airflow. ) Shows an intermediate case between FIG. 4 (a) and FIG. 4 (c). In the case of FIG. 4A, since the wind direction vane 14 is substantially parallel to the ceiling surface 3, it is not necessary to ensure a wide operating area of the wind direction vane 14. Therefore, the amount by which the peripheral panel 10 is lowered by the lifting device 9 is small. On the other hand, in the case of FIG. 4C, since the end portion of the wind direction vane 14 is directed toward the indoor living area, it is necessary to secure a wider operating area of the wind direction vane 14. Therefore, it is necessary to increase the descending amount of the peripheral panel 10 by the lifting device 9. Since the one where the lowering amount of the peripheral panel 10 is smaller looks flatter when viewed from the room, the design is excellent. For this reason, even when the air is blown along the ceiling, the design is impaired if the amount of airflow is uniformly lowered so as to make the airflow feel. Therefore, the designability can be improved by adjusting the descending amount of the peripheral panel 10 according to the blowing direction.

In addition, the amount by which the peripheral panel 10 is lowered by the lifting device 9 may be changed according to the amount of air supplied to the room. For example, FIG. 4A shows a case where the air flow rate is “weak”, FIG. 4B shows a case where the air flow rate is “medium”, and FIG. 4C shows a case where the air flow rate is “strong”. . In the case of FIG. 4A, since the amount of air blown into the room is small, the size of the air outlet 13 may be small. Therefore, the amount by which the peripheral panel 10 is lowered by the lifting device 9 is small. On the other hand, at the time of FIG.4 (c), since there is much ventilation volume to room | chamber interior, the magnitude | size of the blower outlet 13 must be large. Therefore, the descending amount of the peripheral panel 10 by the lifting device 9 needs to be increased. Even in the case where the air flow rate is “small”, if the amount of airflow is uniformly reduced as in the case where the air flow rate is “strong”, the design is impaired. Therefore, the design can be improved by adjusting the descending amount of the peripheral panel in accordance with the air flow rate.

In the ceiling-embedded air conditioner according to the first embodiment, the wind direction vane provided at the air outlet is provided on the back surface of the decorative panel. Therefore, even when the four wind direction vanes are fixed or operating in a predetermined direction during operation, they are not visually recognized by the user, so that a design effect is not impaired.

Embodiment 2
The central panel of the ceiling-embedded air conditioner according to the first embodiment is a rectangular plate, and the peripheral panel and the central panel are separate and separated during operation, whereas the ceiling according to the second embodiment The central panel of the embedded air conditioner has a rectangular lattice shape, and the peripheral panel and the central panel are integrated.

The ceiling-embedded air conditioner according to Embodiment 2 will be described with reference to FIGS. FIG. 5 is a side sectional view when the operation of the ceiling-embedded air conditioner according to the second embodiment is stopped, and FIG. 6 is a diagram illustrating the indoor side when the operation of the ceiling-embedded air conditioner according to the second embodiment is stopped. FIG. 7 is a side cross-sectional view of the ceiling-embedded air conditioner according to Embodiment 2 during operation. In the second embodiment, differences from the first embodiment will be mainly described, and the same configurations and effects as those of the first embodiment will be omitted. Further, the same reference numerals are used for the same configurations as those of the first embodiment.

As shown in FIGS. 5 and 6, the decorative panel 17 according to the second embodiment is provided so as to fill the central portion of the square-shaped appearance case 4 and to cover the opening of the main body 2. . The decorative panel 17 is integrally formed with a square-shaped peripheral panel 16 and a square lattice-shaped central panel 15 provided so as to fill the central portion of the peripheral panel 16. The center panel 15 covers the inlet 18 and the peripheral panel 16 covers the outlet. In other words, a square-shaped peripheral panel 16 is arranged inside the square-shaped appearance case 4, and a rectangular lattice-shaped central panel 15 is arranged inside the square-shaped peripheral panel 16. The outer case 4, the peripheral panel 16, and the central panel 15 form a single plate, and these are attached flat to the ceiling surface 3 when viewed from the indoor side. Of course, the appearance case 4, the peripheral panel 16, and the center panel 15 do not have to be completely flat with respect to the ceiling surface 3, as long as they look flat at first glance.

As shown in FIG. 7, the lifting device 9 of the ceiling-embedded air conditioner 1 according to the second embodiment lifts the decorative panel 17, that is, the peripheral panel 16 and the central panel 15 together. When the operation of the ceiling-embedded air conditioner 1 starts, the blower fan 5 starts rotating. Further, in parallel, the lifting device 9 moves the decorative panel 17 to the indoor side. Thereby, indoor air conditioning is started.

When the decorative panel 17 is moved indoors by the elevating device 9, a gap is formed between the peripheral panel 16 and the external case 4, and this gap becomes the air outlet 13 of the ceiling-embedded air conditioner 1. That is, when the operation of the ceiling-embedded air conditioner 1 is stopped, the appearance case 4, the peripheral panel 16, and the central panel 15 are arranged flat on the ceiling surface 3 with no gaps as shown in FIG. The blower outlet 13 is formed when the decorative panel 17 moves to the indoor side during operation without being formed. On the other hand, since the central panel 15 has a lattice shape, a gap between the lattices serves as a suction port 18.

When the operation of the ceiling-embedded air conditioner 1 starts, indoor air is sucked into the main body 2 from the suction port 18. The air sucked into the main body 2 passes through the dust collection filter 7, the blower fan 5, the heat exchanger 6, and the air is conditioned to be blown into the room through the outlet 13.

Thus, in the ceiling-embedded air conditioner according to Embodiment 2, since the peripheral panel and the central panel move together even during operation, there is no step between the peripheral panel and the central panel. Therefore, in addition to the effect which concerns on Embodiment 1, it has the effect that the designability improves further.
