Description

A grill 201 for taking in air from the room is disposed at the center of the panel 2 attached to the lower side of the housing 1, and a filter 202 for removing dust in the air is provided above the grill 201. Further, on the outer periphery of the grill 201, four outlets 211 that are four elongated rectangular openings are formed. From the blower outlet 211, the air whose temperature is adjusted by the indoor unit 90 is sent out indoors. Each air outlet 211 is provided with a louver 203 for adjusting the air blowing direction.

Claims (15)

A centrifugal fan having a hub and a shroud and vanes disposed therebetween;
An indoor heat exchanger disposed so as to surround the centrifugal fan, and an air conditioner including an indoor unit housed in a housing,
The indoor heat exchanger has a flat air inflow surface into which air from an air discharge port of the centrifugal fan flows,
A rectifying member is attached to the air inflow surface,
The rectifying member includes a support portion having an insertion portion fixed between the fins of the air inflow surface, and a wing portion having a shape extending from the support portion in a direction facing the rotation direction of the centrifugal fan, And configured to block a part of the air flowing between the centrifugal fan and the air inflow surface,
An angle formed by the insertion portion and the blade portion in a plane orthogonal to the rotation axis of the centrifugal fan is parallel to the air flow flowing from the air discharge port into the air inflow surface at least on the hub side. Thus, an air conditioner that increases the static pressure of the air upstream and downstream of the blade.   The air conditioner according to claim 1, wherein the support portion and the wing portion on the shroud side increase a static pressure of the air flowing in a direction parallel to the air inflow surface.   The curve seen from the outer peripheral side of the centrifugal fan at the trailing edge of the blade has an inflection point, the hub side is convex and the shroud side is concave toward the rotational direction of the centrifugal fan. The air conditioner according to claim 1 or 2. The air conditioner according to claim 3 , wherein the angle is different between the hub side and the shroud side with a height of the inflection point as a boundary.   The air conditioner according to any one of claims 1 to 4, wherein the indoor heat exchanger has a polygonal shape.   The air conditioner according to claim 5, wherein each of the air inflow surfaces constituting the polygonal shape is provided with one rectifying member.   The said support part is provided with the opening part for flowing a part of the said air which flows in between the said wing | blade part and the said air inflow surface downstream. Air conditioner as described in.   The air conditioner according to any one of claims 1 to 7, wherein an end portion of the wing portion on the shroud side is located on the hub side from an air suction port of the shroud.   The said insertion part of the said support part is attached ahead of the rotation direction of the said centrifugal fan from the position where the distance of the said centrifugal fan and the said indoor heat exchanger becomes the shortest. Air conditioner as described in. Each of the flow regulating members has a plurality of the insertion portions,
The air conditioner according to any one of claims 1 to 9, wherein coordinates of the plurality of insertion portions in a rotation direction of the centrifugal fan are the same. The air conditioner of Claim 9 or 10 which satisfy | fills the relationship represented by following formula (1).
0.2G ≦ W ≦ 0.5G
(Wherein, W is the distance between the insertion part of the support part and the position where the distance between the centrifugal fan and the indoor heat exchanger is closest on the air inflow surface, and G is the centrifugal part) This is the distance between the end of the air inflow surface that is in front of the centrifugal fan in the rotational direction from the position where the distance between the fan and the indoor heat exchanger is closest, and the closest position.) The angle formed by the insertion portion and the wing portion is different between the hub side and the shroud side,
The air conditioner according to any one of claims 1 to 11, wherein a wing portion that connects the two wing portions is provided between the two wing portions having different angles.   The air conditioner according to any one of claims 1 to 12, wherein an angle formed between the insertion portion and the wing portion on the hub side is 135 degrees or less.   The air conditioner according to claim 13, wherein an angle formed by the insertion portion and the wing portion on the shroud side is 115 degrees or less.   The air conditioner according to any one of claims 1 to 14, wherein the support portion has a longer length in a rotation axis direction of the centrifugal fan than the wing portion.
