Abstract

Provided is an air adjuster that maintains low-noise performance of back-inlet types and allows realization of efficient airflow from the front side toward the back side thereof and prevents the occurrence of stagnant air. The air adjuster includes a housing in which air inlets and an air outlet are formed; a blower that sucks in air through the air inlets; and a conditioning unit that conditions the air sucked in by the blower. The air inlets are located on the back side of the housing, and the air conditioned by the conditioning unit is blown to the outside through the air outlet. The housing allows the air to pass through a space between a bottom surface thereof and a placement surface, and the housing is provided with leg units that form a gap whose vertical dimension on the front side is smaller than that on the back side.

Claims

1. An air adjuster comprising a housing in which an air inlet and an air outlet are formed;

a blower that is disposed in the housing and that sucks in air through the air inlet; and

a conditioning unit that is disposed in the housing and that conditions the air sucked in by the blower, the air that has been conditioned by the conditioning unit being blown to the outside through the air outlet,

wherein the air inlet is formed only in a back surface of the housing,

wherein the air outlet is formed in an upper surface of the housing, and

wherein the housing allows the air to pass through a space between a bottom surface thereof and a placement surface, and the housing is provided with a leg wherein the leg unit has a fixed inclination relative to the housing and forms a gap whose vertical dimension on a front side is smaller than a vertical dimension on a back side the gap being open on the front side and the back side to permit air flow from the front side to the back side of the housing via the gap such that the air flow may enter the air inlet.

2. The air adjuster according to claim 1, wherein at least one of a lower end portion of a front surface and a front end portion of the bottom surface of the housing is formed as an inclined surface or a curved surface that is connected to the other of the lower end portion of the front surface and the front end portion of the bottom surface.

3. The air adjuster according to claim 2, wherein the leg unit is a plurality of legs that are disposed at least at three positions on the bottom surface of the housing.

4. The air adjuster according to claim 2, wherein the leg unit is a wall member that has four side portions extending along a peripheral edge of the bottom surface of the housing so as to face downward, an opening is formed in each of a side portion at a front surface side and a side portion at a back surface side.

5. The air adjuster according to claim 1, wherein the leg unit is a plurality of legs that are disposed at least at three positions on the bottom surface of the housing.

6. The air adjuster according to claim 1, wherein the leg unit is a wall member that has four side portions extending along a peripheral edge of the bottom surface of the housing so as to face downward, an opening is formed in each of a side portion at a front surface side and a side portion at a back surface side.
