A motor includes a rotor, a stator, and a magnetic pole position detection element to detect a position of a magnetic pole of the rotor. The rotor includes a resin magnet having a first orientation and a second orientation, and a shaft fixed to the resin magnet, and the first and second orientations and are different from each other in a radial direction. The magnetic pole position detection element faces the resin magnet in an axial direction.

A floor-standing air-conditioning indoor unit and an air conditioner are provided. The indoor unit has a housing, a top air outlet frame, a fan assembly and a driving device. The housing has an air inlet and a mounting port with an upward opening. An air duct is formed between the air inlet and the mounting port. The top air outlet frame is installed at the mounting port and movable up and down. The fan assembly is installed in the air duct and blows airflow to a lower port of the top air outlet frame and out from a front port of the top air outlet frame. The driving device has a driving member and a motion conversion member connected with the top air outlet frame. The driving member drives the motion conversion member to move along the first direction to move the top air outlet frame up and down.

Disclosed are a fresh air assembly (100), an air conditioner indoor unit, and an air conditioner. The fresh air assembly (100) includes a fresh air housing (10) and a fresh air motor (30). The fresh air housing (10) includes a mounting holder (13), the mounting holder (13) has a clamp space (13a), and a surface of the mounting holder (13) away from the clamp space (13a) is defined with a reinforcement rib (1311); and the fresh air motor (30) is mounted in the clamp space (13a).

A local cooler includes: a housing formed into a box shape; a heat exchanger provided along a slope extending upward to a rear portion from a lower position located on the front side of the housing; a first intake/exhaust port provided on a front surface of the housing; a second intake/exhaust port provided on a bottom surface of the housing; third intake/exhaust ports provided at a plurality of locations among side surfaces, upper surface and rear surface of the housing; and a closing plate capable of selectively shielding these intake/exhaust ports.

An indoor unit for an air conditioner, in which a diffuser outlet through which humidified air is discharged is placed between a front panel and a grill that guides the discharged air, may produce the effect that discharged air pushes discharged humidified air, thereby allowing the humidified air to flow far away from a lateral outlet. As a result, formation of droplets on a surface of the front panel made of a metallic material may be minimized.

A rotor includes a rotor core including a magnet insertion hole and an opening and a permanent magnet inserted in the magnet insertion hole and forming a first magnetic pole. The rotor satisfies L1<L2, where L1 is a first maximum width of the opening in a direction perpendicular to a radial direction and L2 is a second maximum width of the opening in the radial direction. A distance from the opening to the magnet insertion hole is smallest at a magnetic pole center of the first magnetic pole.

An air conditioner includes a main body, a fan configured to form an airflow inside the main body, a motor including a shaft to which the fan is coupled, and a motor cover to which the motor is fixed. The motor cover includes a body including a rear surface formed in a truncated cone shape, and a vortex breaker which protrudes toward the fan from the rear surface body along an outer periphery of the body, so as to prevent air, which is discharged from the fan, from forming a vortex.
