摘要:
An indoor unit for air-conditioners, wherein a casing (l0) comprises a flat and parallelopipedal body (11), and a bulging portion (13) continuous from a bottom section of the body (11), a front surface of the bulging portion (13) comprising an inclined surface (14) extending downward from a front side of the casing (10) to a rear side thereof, the inclined surface (14) of the bulging portion (13) having a suction port (41) in the inclined surface (14) thereof, the body (11) having a front outlet (43) in a front surface thereof, and side outlets (44) in each side surface thereof, an air passage formed in the interior of the casing (10) and extending from the suction port (4l) to the outlets (43, 44) being provided therein with a centrifugal fan for sucking the room air from a lower portion thereof and discharging the same from side portions thereof, and a heat exchanger for generating conditioned air.
摘要:
An air conditioner comprising a cylindrical bellmouth (8) for conducting the room air, a centrifugal fan (10) for radially blowing the air sucked through the bellmouth (8), and a heat exchanger (9) provided facing an outlet (10b) of the centrifugal fan (10), all of which being provided in a casing (2). A shroud (5) of the centrifugal fan (10) has a guide section (5c) which is provided radially outwardly of and contiguous to an annular blade support (5b) to extent toward a suction side in an axial direction, the guide section (5c) effectively reducing blast sounds.
摘要:
An air conditioner comprising an outlet (11) from which the air from an indoor heat exchanger (7) is discharged, and closing members (20, 21) which are provided in positions spaced from end portions (11a, 11b) of the outlet (11) by a predetermined distance X toward the central portion thereof, and which are adapted to partially close the outlet (11), whereby, when the cold air from the indoor heat exchanger (7) impinges upon the closing members (20, 21) during a room cooling operation, it can flow in a divided manner through openings on both sides of the closing members (20, 21), end portions of an air directing blade (15) being therefore covered with the cold air to prevent the cold air and indoor air from contacting each other at the mentioned end portions, so that it becomes possible to set flows of the air smooth and minimize the occurrence of dew condensation.
摘要:
An air conditioner of ceiling-embedded type capable of reducing short-circuit without increasing draft by airstream blown from the outlet thereof. The air conditioner (1) is formed such that, at the lower part of a casing (2) in which four panel side parts (30a to 30d) and four panel corner parts (30e to 30h) are alternately and continuously formed, four main blowout flow passages (12a to 12d) are formed along the panel side parts (30a to 30d), auxiliary blowout flow passages (12e to 12g) are formed at three panel corner parts (30e to 30g), and a suction port (31) is formed so as to be surrounded by the panel side parts (30a to 30d). The auxiliary blowout flow passages (12e to 12g) are formed such that the distance thereof from the main blowout flow passages (12a to 12d) adjacent to the auxiliary blowout flow passages (12e to 12g) satisfies a specified dimensional relation.
摘要:
A centrifugal blower having a resin blade wheel of a type that sucks a gas from the rotating shaft direction and blows the gas out in the direction intersecting the rotating shaft, where the blade wheel can be reduced in weight even if blades each extending while being twisted toward the axis direction are adopted. A blade wheel (42) of a blower (4) has an end plate (43), blades (44), and an end ring (45). A blade (44) is composed of a blade body (51) and a blade cover (61). The blade body (51) is fixed to the end plate (43) arranged in an annular pattern with a shaft (41a) as the center. The blade cover (61) is attached to the blade body (51) to form a hollow space (S) between itself and the blade body (51). The end ring (45) is disposed so as to hold the blades (44) between itself and the end plate (43) in the axial direction and is fixed to the end plate (43). The blade cover (61) is disposed so as to form at least a portion of a negative pressure surface (44f) of a blade (44).
