first embodiment
[0060]A first embodiment of the present invention will be described referring to FIGS. 8 to 11. FIG. 8 is a longitudinal section of an indoor unit 91 including the fan rotation axis. FIG. 9 is a transverse section of the indoor unit 91 taken along line D-D of FIG. 8. FIG. 10 is an enlarged perspective view of a rectifying member 920. FIG. 11 is a bottom view of the rectifying member 920 seen from a direction indicated by arrow Z of FIG. 10. In the drawings, the lines s-s, p-p, q-q, and t-t indicate a position of the hub of the centrifugal fan 5, the inflection point position at which the blade rear edge changes its shape from convex to concave, an upper end position of the shroud, and a lower end position of the shroud, respectively. Numeral 811 denotes an air inflow surface of the heat exchanger 8.
[0061]The rectifying member 920 includes a thin plate support 931, a thin plate vane 932 which extends from one end of the support 931 toward a direction opposite a fan rotating direction...
second embodiment
[0088]In this embodiment, the same components as those described in the first embodiment will be designated with the same numerals, and explanations thereof, thus will be omitted so that the difference from the first embodiment will be explained mainly hereinafter.
[0089]FIG. 13 represents the second embodiment according to the present invention. The support 931 of a rectifying member 921 has rectangular openings 941, 942 through which the inflow air between the vane and the air inflow surface 811 of the heat exchanger partially flows to the rear of the support 931. Therefore, even if the vane direction is deviated from the given direction owing to a fitting error, it is possible to suppress the region where the flow velocity is significantly lowered. Adjustment of the number of openings, size and position thereof allows control of the static pressure improvement effect in the fan rotation axial direction.
third embodiment
[0090]FIG. 14 represents a third embodiment according to the present invention. This embodiment is different from the first embodiment in that the support 931 has an extended thin plate section 951 at the lower end. Some of the flowing air around the air inflow surface 811 is blocked in the region below the centrifugal fan 5 so that the amount of air passing through the part of the heat exchanger at an anterior position of a fitted position of the thin plate section 951 increases together with the static pressure. Meanwhile, the part of the thin plate section 951 protruding from the air inflow surface 811 is very low in height. This makes it possible to suppress reduction in the flow velocity behind the part. As a result, the improvement effect of the rectifying member may further be enhanced.
