Further, there is almost no gap or a slight gap between the two ribs 38 and 39 forming the groove 40 and the protrusion 16 inserted into the groove 40. Thereby, it can suppress that air leaks outside from the attachment part of the apparatus main body 10 and the louver 30. FIG.

  The operation | movement which performs air conditioning in the air conditioner 1 of this Embodiment of such a structure is demonstrated.

  In the air conditioner 1, when the fan 14 is driven, room air is taken in from the suction port 31 of the louver 30, and the room air is introduced to the suction side of the air passage 12 of the apparatus body 10 through the suction air passage 33. Air is purified by a filter 13 provided on the air passage 12 of the apparatus main body 10, and the purified air is sent out to the blowing side of the air passage 12 through the inside of the fan 14. Then, air is sent out from the blower outlet 32 into the room through the blowout air passage 33 of the louver 30.

  In the air conditioner 1 according to the present embodiment, the mounting frame 20 to which the apparatus main body 10 is attached is provided with a horizontal plane portion 22 that protrudes inward from the inner peripheral surface of the cylindrical portion 21, and a predetermined lower end of the cylindrical portion 21 A horizontal plane portion 22 is provided so as to be spaced above the distance. By using the space between the lower end of the cylindrical portion 21 and the horizontal plane portion 22, the flange 15 is disposed above the lower surface of the ceiling 2 in a state where the flange 15 of the apparatus body 10 is fixed to the lower surface of the horizontal plane portion 22. Can be arranged. Therefore, a part of the louver 30 disposed so as to contact the lower surface of the flange 15 can be positioned above the lower surface of the ceiling 2. Therefore, the vertical dimension of the louver 30 exposed below the lower surface of the ceiling 2 can be reduced, and the design of the air conditioner 1 visually recognized from the indoor side can be enhanced.

  The louver 30 includes an upper louver portion 37 and a lower louver portion 36, and the lower louver portion 36 having an outer dimension slightly larger than the opening 3 of the ceiling 2 is disposed below the lower surface of the ceiling 2. On the other hand, the upper louver portion 37 having an outer dimension smaller than the opening 3 of the ceiling 2 can be disposed above the lower surface of the ceiling 2. Therefore, the vertical dimension of the louver 30 exposed downward from the lower surface of the ceiling 2 can be reduced by at least the upper louver portion 37, and the design of the air conditioner 1 visually recognized from the indoor side can be improved. Can do.

  In the description of the above embodiment, the case where the mounting frame 20 includes the cylindrical tube portion 21 is taken as an example. However, the shape of the mounting frame is not limited to the rectangular tube shape, and may be a polygonal cylindrical shape or a cylindrical shape. It may be.

  In addition, the air conditioning function of the air conditioner 1 is not limited to the air purification function using the filter 13, and may include a cooling / heating function (heat exchange function), a humidification function, a ventilation function, and the like. Further, a duct may be connected to the apparatus main body 10 so that indoor air is exhausted or supplied through the duct.

  Moreover, although the case where the air leakage prevention structure 5 is comprised by the projection part 16 of the flange 15 and the groove part 40 of the upper louver part 37 was taken as an example, it is not restricted to such a case. For example, the air leakage prevention structure may be configured by the groove portion provided in the flange 15 and the protrusion portion provided in the upper louver portion 37. Further, a sealing member provided between the flange 15 and the upper louver portion 37 may be an air leakage prevention structure.

  It is to be noted that, by appropriately combining any of the above-described various embodiments, the effects possessed by them can be produced.

  The air conditioner of the present disclosure can be applied to a ceiling-embedded air conditioner that performs air conditioning such as purification of indoor air, heat exchange, and ventilation.
