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 facilitate alignment at fastening a shaft by cutting down over two positions on the shaft side at a shaft fastening part into the same form, setting optional one among them to be a drive transmitting plane, and constructing the other cut down parts not to contact with a part to which driving force is transmitted. CONSTITUTION: For fastening an impeller 1 to a driving shaft 3, optional one plane among planes 4a, 4b, 4c is set as a driving force transmitting plane, and positioned against a plane 2b to which driving force is transmitted. Any one of the planes 4a, 4b, 4c can be used as the plane to which driving force is transmitted, and hence alignment at fastening can be easily executed. Further, the fitting directions are three directions of 4a, 4b, 4c, and hence workability is improved. When the impeller 1 is fastened to the driving shaft 3 setting the plane 4a as the driving force transmitting plane, the planes 4b, 4c are not contacted with the impeller 1. Hereby, vibration and noise of an electric motor transmitted from the driving shaft 3 to the impeller 1 can be restrained.

摘要： PURPOSE:To contrive to lower a noise of an indoor machine by lowering a vibration which transfers to a box body from a drain pump driving motor. CONSTITUTION:A drain pump driving motor is fastened to a drain pump supporting material 59 through a vibration preventing rubber 58 by a non- magnetic bolt 57. The bolt 57 is inserted into a hole of the vibration preventing rubber 58 with almost non-touching condition, and is so composed that a vibration from a motor does not transfer to the drain pump supporting material 59. Accordingly, a noise caused by an electromagnetic vibration from the drain pump driving motor can be largely decreased, and a lowering of the noise sound of an indoor machine can be contrived.

摘要： PROBLEM TO BE SOLVED: To provide an indoor unit for an air conditioner capable of quickly reducing a temperature difference between an upper part and a lower part inside a room.
SOLUTION: The indoor unit is structured by arranging an indoor unit main body 1 near a ceiling, providing a ventilation duct 3 to stand from a floor surface along a wall, forming the ventilation duct 3 with a lower suction opening 25 at a part near the floor surface, and connecting an upper end of the ventilation duct 3 to a main body suction opening 13 of the indoor unit main body 1. When a temperature difference is generated in the air of the upper part and the lower part and temperature near the floor surface is lowered, flowing speed of the blowing air is increased and a circulating flow rate is increased to increase the heating power during the heating operation, and the temperature difference between the upper part and the lower part can be quickly reduced, and during the cooling operation, the blowing quantity of the cold air as a cause of the generation of temperature difference between the upper part and the lower part is reduced to reduce the cooling power, and a temperature difference can be quickly reduced.

摘要： PROBLEM TO BE SOLVED: To increase the flow velocity in the end part in a turning shaft direction of a wind direction plate without lowering a wind direction adjusting function and the flow rate of a blowoff air. SOLUTION: Auxiliary wind direction plates 33 are disposed in the wind receiving surface side of a main wind direction plate 30 retained in a set attitude and the end part in the direction of the turning shaft 31 of the main wind direction plate, and the auxiliary wind direction plate 33 is retained in such an attitude as correcting the air flow flowing toward the end part in the direction of the turning shaft 31 of the main wind direction plate in the set direction so as to increase the flow velocity in the end part. This constitution can avoid an indoor air involved in the air flow blowing from a blowoff port 20 from contacting on the rear surface of the main wind direction plate 30 so as to suppress dew condensation on the main wind direction plate 30. The wind direction of the outlet air can be adjusted by the main wind direction plate 30 so as to prevent the instantaneous suction of the blowoff air and to suppress the lowering of the heating and cooling capacities of the air conditioner.
