摘要： Each fin of a heat sink includes a main fin connected to a core and extending radially outwards, and a pair of branch fins extending radially outwards from a branch point at a radially outer end of the main fin. Among a plurality of fins, in each of three fins which are adjacent in the circumferential direction, a width of an end portion of the main fin viewed along the center axis expands radially outwards at an angle which is larger than an expanding angle of the pair of branch fins. A difference between a distance from the center axis to the branch point in the center one of the fins and a distance from the center axis to the branch point in each of the other two fins is equal to or larger than a width of a root of the main fin in the center radiating fin.

摘要： A hair dryer includes a fan motor, a heater unit, and a body case arranged to cover the fan motor and the heater unit, and arranged to extend in a front-rear direction around a central axis. The fan motor includes an impeller arranged to rotate about the central axis, and a motor arranged to rotate the impeller. The body case includes an intake case portion including an air inlet, a discharge case portion including an air outlet, and an admission case portion arranged between the air inlet and the air outlet, and including an admission inlet. The intake case portion includes a suction tube portion arranged to extend toward the admission inlet. The intake case portion and the admission case portion are arranged to together define an expansion chamber arranged between the admission inlet and the air inlet and radially outside of the suction tube portion and the admission inlet.

摘要： A fan motor includes a motor, an impeller and a housing. The housing includes an inner wall portion, a silencer portion, and a communicating opening. The inner wall portion extends along a rotation axis to assume a tubular shape, and houses at least a portion of the impeller therein. The silencer portion includes a portion radially outside of the inner wall portion, and defines a silencing space between the inner wall portion and the silencer portion. The communicating opening brings a space inside of the inner wall portion into communication with the silencing space. A portion of the communicating opening is defined by an end portion of the inner wall portion on an inlet side. The silencing space covers only a portion of the circumferential extent of the inner wall portion. This allows the silencing space to be arranged in a dead space around the inner wall portion.

摘要： A ceiling fan blade, which is rotated by a motor unit having a center axis extending in an up-down direction, includes a blade body extending in a radial direction and including at least one slit opened at a rotation direction rear edge of the blade body. On a circumferential cross section including a rotation direction front end of the slit of the blade body, a lower end of a rotation direction front edge of the blade body is positioned at a center axis direction upper side of a lower end of the rotation direction front end of the slit. Further, a lower end of an open end of a radial outer edge of the slit is positioned axially downward of the lower end of the rotation direction front end of the slit and is positioned axially upward of a lower end of an open end of a radial inner edge of the slit.
