PROBLEM TO BE SOLVED: To improve a cooling heating effect by a method wherein indoor air is caused to perform effective convection and an indoor temperature is uniformalized on a whole. SOLUTION: In an indoor air convection device to arrange an indoor ceiling surface 10 and through forced convection of indoor air, an indoor temperature is uniformalized, a device body is formed in the shape of a box having a side being opened and a fan 16 to effect convection of indoor air is incorporated in the device body, a shield plate 20 to vertically divide the opening part into two sections and having an edge part extending to the side of a device body is arranged at the opening part of the side of the device body. The fan 16 is provided with an intake blade part 16a to introduce indoor air through an opening between the under surface of the device body and the shielded plate, and an air supply blade part 16b to feed air, introduced by an intake blade part, through an opening part between the shielded plate 20 and the ceiling surface 10 along the ceiling surface. |
