Abstract

A duct apparatus which is connected to an air conditioner and has therein a tubular duct through which conditioned air circulates, includes: an opening portion provided in the duct which extends along a flowing direction of the conditioned air which flows in, the opening portion being provided in such a manner as to extend along the flowing direction of the conditioned air; and a plate-shaped air guiding portion for covering the opening portion, wherein the air guiding portion has a plate thickness of 1.0 mm or more, and has a plurality of air guiding holes allowing an interior of the duct to communicate with an outside and arranged along the flowing direction of the conditioned air.

Claims

1. A duct apparatus which is connected to an air conditioner and has therein a tubular duct through which conditioned air circulates, comprising:

an opening portion provided in the duct which extends along a flowing direction of the conditioned air which flows in, the opening portion being provided in such a manner as to extend along the flowing direction of the conditioned air; and

a plate-shaped air guiding portion for covering the opening portion,

wherein the air guiding portion has a plate thickness of 1.0 mm or more, and has a plurality of air guiding holes allowing an interior of the duct to communicate with an outside and arranged along the flowing direction of the conditioned air.

2. The duct apparatus according to claim 1, wherein the plate thickness of the air guiding portion is 2.0 mm or more.

3. The duct apparatus according to claim 1, wherein an area of an opening of each of the air guiding holes is 500 mm² or less.

4. The duct apparatus according to claim 1, wherein an area of an opening of each of the air guiding holes is 7.0 mm² or more.

5. The duct apparatus according to claim 1, wherein a proportion of the air guiding holes in an outside side surface of the air guiding portion is 10 to 60%.

6. The duct apparatus according to claim 5, wherein the proportion of the air guiding holes in the outside side surface of the air guiding portion is 20 to 50%.

7. The duct apparatus according to claim 1, wherein the air guiding holes are formed at intervals of 5.0 mm or more.

8. The duct apparatus according to claim 1, wherein the shape of an opening of the air guiding hole is a polygon surrounded by four or more line segments.

9. The duct apparatus according to claim 1, wherein the shape of an opening of the air guiding hole is circular.
