Abstract: Blower includes: scroll casing, centrifugal impeller and a motor. Scroll casing includes: recessed portion formed outside lateral plate concentrically with centrifugal impeller; inner-circumferential flat portion disposed more on an inner circumference than recessed portion; and outer-circumferential flat portion disposed more on an outer circumference than recessed portion. Bottommost surface of recessed portion is disposed on a same plane as lateral plate end surface of lateral plate. Angle ?a made by inner-circumferential flat portion and recessed portion inner surface of recessed portion on an inner circumference is set to a value which falls within a range of 90° or more to 120° or less.

Abstract: A blower includes: centrifugal impeller disposed in inside of casing; and motor which is configured to drive centrifugal impeller. Annular projecting portion which projects in a direction toward the outside of the casing and is concentric with centrifugal impeller is provided around inflow port of casing which faces a fixing-member of centrifugal impeller. Projecting portion includes: raised wall which is raised so as to be away from centrifugal impeller parallel to a direction of the rotary shaft; and flat portion formed in an extending manner in a direction toward inflow port from raised wall. Projecting portion further includes inflow wall which falls toward the centrifugal impeller from an end surface of flat portion toward an inflow port. Flat portion is parallel to an upper end surface of centrifugal impeller.

Abstract: A blower includes: centrifugal impeller (24) disposed in inside of casing (14); and motor (21) which is configured to drive centrifugal impeller (24). Annular projecting portion (14a) which projects in a direction toward the outside of the casing and is concentric with centrifugal impeller (24) is provided around inflow port (12) of casing (14) which faces a fixing-member (23) of centrifugal impeller (24). Projecting portion (14a) includes: raised wall (25) which is raised so as to be away from centrifugal impeller (24) parallel to a direction of the rotary shaft (21a); and flat portion (26) formed in an extending manner in a direction toward inflow port (12) from raised wall (25).

Abstract: Air blower incorporates in housing thereof: suction port; a high pressure air generating portion; a blowout port; first air passage; introduction air suction port; introduction air mixing portion; introduction air blowout port; and second air passage.

Abstract: A control method for drying clothes is disclosed. The method finds a difference in surface temperature between clothes catching air blow and the same clothes catching no air blow, and then determines a degree of dryness in the clothes based on the difference. Based on the degree of dryness, the method determines at what time heating should start.
