Abstract: An air conditioning device includes an air conditioning case defining an air passage through which air flows to an air-conditioning target space, and an air cooler arranged inside the air conditioning case to cool air by absorbing heat from air. The air conditioning device further includes a blower fan arranged inside the air conditioning case on a downstream side of an air flow of the air cooler to generate an air flow passing through the air cooler, and a resonator provided outside the air passage. The resonator includes a cavity portion having a predetermined volume and a communication portion that allows communication between the cavity portion and the air passage. The cavity portion is provided with a partition member that divides an internal space of the cavity portion into multiple closed spaces, and each of the multiple closed spaces communicates with the air passage via the communication portion.

Abstract: A blower includes a motor with variable rotational speed, and a first controller. The motor has a shaft supported by a bearing with a lubricant sealed in. The first controller rotationally drives the motor. The first controller executes first control to decrease the rotational speed of the motor when a first temperature, which is the temperature of the bearing, decreases during operation in which the motor is rotated in a predetermined low rotational speed range. This air conditioner includes: an indoor unit having the blower, a temperature sensor that measures the first temperature, and a heat exchanger; and a second controller that controls the blower to perform air conditioning operation in a space to be air-conditioned in which the indoor unit is installed.

Abstract: A fresh air module and an air conditioner are provided. The fresh air module has a housing and a fan assembly. The housing has a fresh air duct inside the housing. The fan assembly has a motor and a wind wheel disposed in the fresh air duct. The motor has a motor body and a motor shaft. The motor shaft drives the wind wheel to rotate, so as to guide airflow to flow through the fresh air duct. The motor cover is arranged on the housing and outside of the fresh air duct. A motor accommodating cavity is defined in the motor cover and accommodates the motor body. A partition member is formed between the motor accommodating cavity and the fresh air duct to separate the motor accommodating cavity from the fresh air duct. The motor shaft penetrates through the partition to connect with the wind wheel.

Abstract: A rotor includes a rotor core having magnet insertion holes in a number corresponding to a pole number, and a center hole. The rotor core has first slits and ribs alternately arranged in the circumferential direction along a periphery of the center hole, and second slits on an outer side with respect to the first slits in the radial direction. The first slits and the second slits are both equal in number to half or an integer multiple of the pole number. Each second slit is formed to cover the rib from an outer side in the radial direction. Each first slit has a length A1 in the circumferential direction and a width A2 in the radial direction. Each second slit has a length B1 in the circumferential direction and a width B2 in the radial direction. A1>A2, B1>B2, and A1>B1 are satisfied.
