Abstract: An indoor unit includes axial-flow fans, which are provided on downstream of an air inlet. Further, a plurality of first bars are provided to the air inlet. In plan view, leading edge portions of blades of the axial-flow fan are inclined in a direction of rotation of the axial-flow fan from a rotary shaft side of the axial-flow fan to an outer peripheral side. Further, in plan view, the plurality of the first bars are inclined in a direction opposite to the direction of rotation of the axial-flow fan from the rotary shaft side of the axial-flow fan to the outer peripheral side.

Abstract: An indoor unit for an air-conditioning apparatus includes a plurality of axial-flow fans arranged side by side in a horizontal direction below an air inlet. Further, the indoor unit includes a plurality of filters provided to the air inlet so as to be arranged side by side. A cleaning mechanism and a dust box are further provided to the air inlet. Further, the dust box is arranged at a position between adjacent filters and adjacent axial-flow fans.

Abstract: An indoor unit for an air-conditioning apparatus includes a cartridge provided to an air inlet so as to be freely mountable and dismountable. The cartridge accommodates a filter so as to be freely movable in a right-and-left direction and has an opening port formed in one end portion in the right-and-left direction. A dust box is provided on a side of the end portion of the cartridge. The dust box includes a cleaning mechanism configured to clean the filter and a dust collecting portion configured to collect dust.

Abstract: Provided is a thermistor fixing structure capable of facilitating insertion of a thermistor into a temperature sensitive cylinder, and preventing the thermistor from easily dropping off the temperature sensitive cylinder. In a thermistor fixing structure (4000), a fixture (400) for pressing a thermistor (80) against an inner surface of a temperature sensitive cylinder (90) includes an inner bending section (20) formed at one end portion (12) of a longitudinal section (10) so as to function as a stopper for the thermistor (80) inserted into the temperature sensitive cylinder (90) from a cylinder insertion end (95), an outer bending section (50) formed at the one end portion (12) of the longitudinal section (10) so as to be opposed to a cylinder stop end (94), and an inner folding section (30) and an outer folding section (60) formed at another end portion (13) of the longitudinal section (10) so as to sandwich a cylinder top surface of the temperature sensitive cylinder (90).
