Benefits of technology

The patent text describes an air conditioning indoor unit that can deliver conditioned air in a wider range of directions while keeping the pressure loss low. Additionally, the unit ensures a reliable spread of conditioned air in the right and left direction and reduces the number of air flow direction guide blades. It also spreads the direction in which conditioned air is supplied even more in the right and left direction and prevents air from flowing in the wrong direction.

Problems solved by technology

Conventionally, wall-mounted air conditioning indoor units have been required to blow out conditioned air more widely in the right and left direction from the air outlet because the position where the air outlet can be disposed is limited in comparison to ceiling-suspended air conditioners.

Abstract

A wall-mounted air conditioning indoor unit includes a casing, and an air flow direction adjustment unit with plural guide blades positioned between right and left side walls of the outlet passage of the casing. A first of the guide blades is positioned closest to a predetermined side wall of the right and left side walls. In a state in which the first guide blade is postured closer to the predetermined side wall as the first guide blade extends on a downstream side, first and second gaps are formed between first and second sections of the first guide blade and the predetermined side wall, respectively. The first section is part of an end portion of the first blade on the downstream side. The second section is outside the first section. The first gap is equal to or less than 10 mm. The second gap is greater than 10 mm.

Description

TECHNICAL FIELD[0001]The present invention relates to an air conditioning indoor unit.BACKGROUND ART[0002]Conventionally, wall-mounted air conditioning indoor units have been required to blow out conditioned air more widely in the right and left direction from the air outlet because the position where the air outlet can be disposed is limited in comparison to ceiling-suspended air conditioners.[0003]For example, the air conditioner described in patent document 1 (JP-A No. S62-10553) employs a structure where, focusing on the point that the right and left side walls of the air outlet obstruct the conditioned air from being blown out more widely in the right and left direction, the right and left side walls of the air outlet are curved in such a way that the right and left direction width of the air outlet expands in the direction in which the conditioned air is blown out. This air conditioner employing a shape in which the right and left side walls of the air outlet are expanded keep...
