Abstract

An air conditioning indoor unit includes a body, a panel, and a horizontal flap. The body is provided with an air outlet. The panel is positioned to cover the front of the body. The horizontal flap is able to vary the air direction of conditioned air blown out from the air outlet. A recess recessed toward the back side of the air conditioning indoor unit is disposed between an upper edge of an open peripheral edge of the air outlet and a lower end of the panel. During non-operation, the recess and the air outlet are covered by the horizontal flap.

First claim

What is claimed is:

1. An air conditioning indoor unit, comprising:
a body including an air outlet, the air outlet having an upper edge defined by an upper edge member;
a panel positioned to cover a front of the body; and
a horizontal flap able to vary an air direction of conditioned air blown out from the air outlet,
a recess recessed toward a back side of the body, the recess being disposed between the upper edge of the air outlet and a lower end of the panel, the upper edge member frontwardly projecting toward the lower end of the panel so that the recess is partially defined by an upwardly facing surface of the upper edge member, and
during non-operation, the recess and the air outlet being covered by the horizontal flap.

2. The air conditioning indoor unit according to claim 1 , wherein
the recess is located above the upper edge of the air outlet in the body.

3. The air conditioning indoor unit according to claim 1 , wherein
a cross-sectional area of the recess is at least 10 mm 2 and is perpendicular to a longitudinal direction of the air conditioning indoor unit.

4. The air conditioning indoor unit according to claim 1 , wherein
the body further includes an inclination surface between an upper edge of a perimeter of the recess and the lower end of the panel,
the inclination surface is inclined toward the back side of the body, and
during non-operation, the recess, the air outlet, and the inclination surface are covered by the horizontal flap.

5. The air conditioning indoor unit according to claim 1 , further comprising
a fan positioned in the body and generating a flow of air having been sucked into the body toward the air outlet,
the body further including
a grille including a front surface, the panel being positioned in front of the front surface, and
the upper edge member, the upper edge member being a scroll extending from a front of the fan to the air outlet to guide conditioned air to the air outlet,
a front end of the scroll projects more frontwardly relative to a portion of the front surface located in the neighborhood of the air outlet.

6. The air conditioning indoor unit according to claim 2 , wherein
a cross-sectional area of the recess is at least 10 mm 2 and is perpendicular to a longitudinal direction of the air conditioning indoor unit.

7. The air conditioning indoor unit according to claim 2 , wherein
the body further includes an inclination surface between an upper edge of a perimeter of the recess and the lower end of the panel,
the inclination surface is inclined toward the back side of the body, and
during non-operation, the recess, the air outlet, and the inclination surface are covered by the horizontal flap.

8. The air conditioning indoor unit according to claim 2 , further comprising
a fan positioned in the body and generating a flow of air having been sucked into the body toward the air outlet,
the body further including
a grille including a front surface, the panel being positioned in front of the front surface, and
the upper edge member, the upper edge member being a scroll extending from a front of the fan to the air outlet to guide conditioned air to the air outlet,
a front end of the scroll projects more frontwardly relative to a portion of the front surface located in the neighborhood of the air outlet.

9. The air conditioning indoor unit according to claim 3 , wherein
the body further includes an inclination surface between an upper edge of a perimeter of the recess and the lower end of the panel,
the inclination surface is inclined toward the back side of the body, and
during non-operation, the recess, the air outlet, and the inclination surface are covered by the horizontal flap.

10. The air conditioning indoor unit according to claim 3 , further comprising
a fan positioned in the body and generating a flow of air having been sucked into the body toward the air outlet,
the body further including
a grille including a front surface, the panel being positioned in front of the front surface, and
the upper edge member, the upper edge member being a scroll extending from a front of the fan to the air outlet to guide conditioned air to the air outlet,
a front end of the scroll projects more frontwardly relative to a portion of the front surface located in the neighborhood of the air outlet.

11. The air conditioning indoor unit according to claim 4 , further comprising
a fan positioned in the body and generating a flow of air having been sucked into the body toward the air outlet,
the body further including
a grille including a front surface, the panel being positioned in front of the front surface, and
the upper edge member, the upper edge member being a scroll extending from a front of the fan to the air outlet to guide conditioned air to the air outlet,
a front end of the scroll projects more frontwardly relative to a portion of the front surface located in the neighborhood of the air outlet.
