Abstract: A drying device of a washing machine includes a housing with a perforated drum disposed in the housing. A stationary drum is provided around the perforated drum forming a clearance between them. A plurality of radially extending and circumferentially spaced ribs project outward from the wall of the perforated drum to a position adjacent to the stationary drum.

Abstract: A warming fan with a speed reducing device comprises a choke coil which connects with the running inductor of the power set of the warming fan, a diode which is paralleled to the choke coil and a choke coil which is paralleled to the above-mentioned choke coil and connected in series with the diode in the downstream of the same. The warming fan can keep its revolution speed low enough and keep its revolution torque high enough, because the power set of the warming fan is driven by a relatively high voltage corresponding to its revolution speed, but which is interrupted intermittently.

Abstract: A multiuse fan includes a housing enclosing an electrically driven fan for providing a flow to air from a grilled air inlet to a grilled air outlet through a generally circular electric heater assembly in the housing. The heater assembly includes a grating formed by a plurality of spaced, parallel, radially extending metallic heating plates, each having inner and outer portions inclined with respect to each other and which form an intermediate ring-like summit portion at the juncture of the inner and outer portions. The inner end of each plate is connected to an inner ring member coaxial with the fan and the outer end of each plate is joined to an outer ring attached to the housing. An electric heating ring member is positioned in an annular groove provided in the summit portion. Controls permit the fan to be engaged alone to merely circulate air or the fan heating ring to be simultaneously energized to heat and circulate the air.
