Abstract: A shoe care device includes an inner cabinet, an air supply device that is configured to blow air to an accommodated space of the inner cabinet and includes a plurality of dehumidifying materials separate from one another, and a controller configured to control the air supply device. The air supply device includes a connection path configured to circulate air between an inlet and an outlet of the inner cabinet, and a regeneration path branched from the connection path and configured to guide air having passed through at least one of the dehumidifying materials to a portion of the air supply device other than the inlet. The controller is configured to control the air supply device to selectively open and close at least one of the connection path or the regeneration path based on whether or not at least one of the dehumidifying materials is heated.

Abstract: A motor includes a rotary shaft having at least one spray hole for spraying a cooling fluid, a rotor installed on the rotary shaft, and a stator surrounding an outer circumference of the rotor, wherein the rotor includes a plurality of rotor blocks arranged on an outer circumference of the rotary shaft. Each of the rotor blocks may include a magnet installed at a rotor core and a cooling guide may be disposed between a pair of the plurality of rotor blocks and form a spray flow path for guiding a cooling fluid that has passed through the spray hole to be sprayed in a direction toward an inner circumference of the stator.

Abstract: An electric motor includes a housing, a stator assembly disposed in the housing, a rotor assembly rotatably disposed in the stator assembly, and an impeller configured to be rotated by the rotor assembly and to generate a flow of air. The stator assembly defines an inner flow path configured to guide a part of the air to pass through an inside of the stator assembly. The housing defines a bypass flow path at an outside of the stator assembly, where the bypass flow path is configured to guide another part of the air to bypass the stator assembly.
