Provided in place. Next, a screw fixing convex portion 11 having a screw fixing hole at the center is provided on the opposite longitudinal side which is one side opposite to the hooking claw 10. One fixing claw 12 is provided at each end in the short direction perpendicular to the side on which the screw fixing convex portion 11 is provided. As shown in FIG. 4, a non-combustible material 13 is provided inside the four sides of the side panel 6.

  The hooking claw 10 provided on one side in the longitudinal direction of the side panel 6 is configured to be locked to the opening end of the decorative panel 4. The screw fixing convex portion 11 provided on the opposite side of the hooking claw 10 has a convex shape extending from the side panel 6 so that the side panel 6 can be fixed with a screw from below when the side panel 6 is attached to the decorative panel 2. It has a screw fixing hole.

  As shown in FIG. 3, when the side panels 6 provided on both the left and right sides of the suction port are removed from the decorative panel 2, openings 9 that allow the inside of the ceiling to be viewed are provided respectively. A non-combustible material 13 is provided on the facing surface of the side panel 6 corresponding to the opening 9 of the decorative panel 2 and receives foreign substances that fall or adhere to the decorative panel 2 side from the inside of the ceiling.

  FIG. 5 is a sectional view showing the screw fixing convex portion 11 of the left and right side panels in the first embodiment of the present invention, and FIG. is there. 5 and 6, the screw fixing convex portions 11 of the side panels 6 on both the left and right sides of the suction port 3 including the suction grill 5 are located between the suction grill 5 and the decorative panel body 2. In addition, in the upper part of the left and right side panels 6 on the inside of the ceiling, an electrical component 14, a pipe connection portion 15, and a hanging fitting 16 of a ceiling-embedded air conditioner (indoor unit) are positioned.

Next, the operation will be described.
In the ceiling-embedded air conditioner 1 configured in this way, the left and right side panels 6 of the suction port 3 having the suction grille 5 are provided on the side panel 6 when attached to the decorative panel 2. The three hooking claws 10 are hooked on the decorative panel body, and then the two fixing claws 12 are hooked on the decorative panel body, and are fixed by the screws 8 through the screw fixing holes of the screw fixing convex portion 11. Next, the suction grill 5 is attached to the decorative panel body.

  When each of the suction grill 5 and the side panel 6 is removed from the decorative panel 2, the decorative panel 2 can be easily opened by performing a procedure reverse to the attachment.

  As described above, with the decorative panel 2 attached to the ceiling-embedded air conditioner main body 1, the hanging bracket of the indoor unit main body 1 from below the indoor side through the opening 9 provided in the decorative panel 2. Work access to 16 is possible. The operator can adjust the hanging position of the indoor unit body 1 by inserting a hand with a tool from the opening 9. Similarly, work access can be made from the opening 9 to the electrical equipment 14 and the pipe connection portion 15 of the indoor unit main body, so that installation workability is improved.

  Moreover, since the incombustible material 13 is provided inside the side panel 6, even if the electrical product 14 and the pipe connection portion 15 of the ceiling-embedded air conditioner main body 1 are burnt down due to an external fire, they spread to the indoor side. Can be prevented by the side panel 6.

  FIG. 7 is a diagram illustrating a configuration example of a ceiling-embedded air conditioner according to the present invention. Here, FIG. 7 shows an example of a ceiling-embedded air conditioner in which an outdoor unit constituting a refrigeration cycle and an indoor unit connected by a refrigerant pipe are combined. In FIG. 7, the same operations as those described in FIG. 1 and the like are performed. The air conditioner in FIG. 7 connects an outdoor unit (outdoor unit) 200 and the indoor unit (indoor unit) 100 described in Embodiment 1 through a gas refrigerant pipe 300 and a liquid refrigerant pipe 400.

  The indoor unit 100 includes a fin-and-tube heat exchanger, for example, and includes an indoor heat exchanger 110 that exchanges heat between indoor air and refrigerant. Moreover, the indoor unit 100 has an indoor blower attached to the indoor heat exchanger 110. The indoor blower is a cross flow fan centrifugal blower, for example, which sucks indoor air and blows it to the indoor heat exchanger 110.

  The outdoor unit 200 includes a compressor 210, a four-way valve 220, an outdoor heat exchanger 230, and an expansion valve 240. The compressor 210 compresses and discharges the sucked refrigerant. Here, although not particularly limited, the compressor 210 can change the capacity of the compressor 210 (the amount of refrigerant sent out per unit time) by arbitrarily changing the operation frequency, for example, by inverter control. You may be able to do it. The four-way valve 220 is a valve that switches the flow of the refrigerant, for example, between the cooling operation and the heating operation.

  Outdoor heat exchanger 230 in the present embodiment performs heat exchange between the refrigerant and air (outdoor air). For example, it functions as an evaporator during heating operation, evaporating and evaporating the refrigerant. Moreover, it functions as a condenser during the cooling operation, and condenses and liquefies the refrigerant.

  An expansion valve 240 such as a throttle device (flow rate control means) decompresses the refrigerant to expand it. For example, in the case of an electronic expansion valve or the like, the opening degree is adjusted based on an instruction from a control device (not shown) or the like. For example, the indoor heat exchanger 110 performs heat exchange between air to be air-conditioned and a refrigerant. During heating operation, it functions as a condenser and condenses and liquefies the refrigerant. Moreover, it functions as an evaporator during cooling operation, evaporating and evaporating the refrigerant.

  By configuring the air conditioner as described above, the heating operation and the cooling operation can be realized by switching the refrigerant flow by the four-way valve 220 of the outdoor unit 200.
