摘要： PROBLEM TO BE SOLVED: To make the outdoor unit of an air conditioner compact and silent by providing a protrusion toward radial outward of a propeller fan and making a hole for introducing the air into a housing constituting the protrusion in the side wall on the upstream side of the propeller fan. SOLUTION: A protrusion 11a is provided on the wall of a housing proximate to a propeller fan 1 on the side opposite to a heat exchanger 3 toward the outside of the housing and a hole 11b for introducing the air into the housing is made in the side wall on the upstream side of the propeller fan constituting the protrusion 11a. Since the volume of air is balanced between then heat exchanger 3 side and the opposite side by the air introduction hole 11b, pressure fluctuation on the wall, face is suppressed as compared with an outdoor unit having no air introduction hole 11b. Since a protrusion is provided toward radial outside of the propeller fan, distance between the wall face of the housing and the outer edge of the fan is increased thus suppressing pressure fluctuation on the wall face furthermore.

摘要： PROBLEM TO BE SOLVED: To reduce a quantity of materials to be used, reduce a cost, improve strength, and reduce a noise by providing lattice-shaped ribs arranged on the inside diameter side from a specific % position of a radius of a fan on a negative pressure surface of fan blades. SOLUTION: Plural fan blades 7 are obliquely arranged in a radial shape in the radial direction to a shaft hole 3 on an outer peripheral surface of an annular ring-shaped hub 2 having the shaft hole 3 in the center. A peripheral directional rib 4 and a radial directional rib 5 are ribs arranged in a lattice shape. These are arranged in a plurality on the inside diameter side from a 50% position of an effective redius of a fan 1 on an anti-rotation side surface (a negative pressure surface 9) of the fan blades 7 with an outer peripheral surface of the annular ring-shaped hub 2 as a reference. Therefore, the vicinity of the annular ring-shape hub 2 is arranged in a lattice shape, but an outer peripheral part and the radial direction are constituted of minimum ribs of a range where the blades 7 are not deformed. Therefore, rigidity of the baldes 7 is largely improved, a quantity of materials to be used is reduced, a cost is reduced, strength is improved, and a noise can be reduced.

摘要： PURPOSE:To improve efficiency of an indoor air conditioner by shifting a nose part as the winding start of the spiral form of a scroll casing from the finishing part thereof so as to from a step and dividing a discharging port into parts. CONSTITUTION:In a scroll casing 6 used for a left and right suction type centrifugal blower 7, by shifting a nose part 8 as the winding start of a spiral form from a winding end part 9 thereof in a width direction so as to form a step, a discharging port is divided into two parts and the direction of a ejected wind is caused to change in two directions indicated by arrows 10 and 11. Thus, since a flow ejected from the left and right suction type centrifugal blower is naturally distributed in two directions in the blowing out port of the 2-divided scroll casing, it is not necessary to forcibly incline a blower attaching plate 3 as in the case of a conventional air conditioner centrifugal blower, its distance to a ceiling plate is shorter, thus reducing a factor for casing reduction in blower performance and assembling of the indoor air conditioner for two direction of blowing out is simplied.
