Therefore, the contact area with the warm air flowing into the lower air-conditioning air passage 2 is increased, and the warm air flowing into the lower air-conditioning air passage 2 is formed by the inverted concave portion 19 and the lower protrusion 18. The turbulent flow comes into contact with the uneven portion, and the turbulent flow comes into contact with the lower surface of the panel board 4 constituting the lower air-conditioning air passage 2 on average, so that the efficiency of conduction of warm air to each panel board 4 is increased. It is heated quickly and the heated state can be maintained as it is.
[0041]
Then, the lower lining 14 is directly heated by the warm air sent to the upper air-conditioning air passage 3 and the lower lining 14 in contact with the upper projection 20 of each of the heated panel boards 4 is indirectly heated. Thereby, the warm air from the heated underlay 14 is radiated into the room R through the floor finishing material 15 to heat the room R.
[0042]
Further, the warm air blown into the lower air-conditioning air passage 2 is blown into the room R from the slit 6 of the grill 5 provided near the wall 23a to heat the room R, A window is formed in the room R to suppress the cool air in the perimeter section, into which cool air enters from the outside, and further increase the heating efficiency.
