A setting facilitation apparatus () includes a keyword input reception section (), a control command selection section (), and a specific control registration section () and is used to facilitate setting of specific control in a control system () that controls a control device through sound inputs. The keyword input reception section () receives an input of information corresponding to a keyword. The control command selection section () displays a certain control command to the control device () on an edit screen (G) and receives selection of the control command. The specific control registration section () registers a keyword (K) input by the keyword input reception section () and the control command selected by the control command selection section () to a specific control (DBT) while associating the keyword and the control command with each other.

Device control system

A propeller fan includes a rotary blade hub driven in rotation about a rotation axis, and a rotary blade installed at an outer periphery of the rotary blade hub. The rotary blade includes a rotary blade body protruding from an outer peripheral surface of the rotary blade hub, and a rib formed on an outer peripheral edge portion of a pressure surface of the rotary blade body so as to extend along an outer peripheral edge of the rotary blade body.

Propeller fan and blower unit

A cross flow fan includes a support plate and an impeller with a plurality of blades disposed on the support plate at predetermined intervals. On each blade, a radius of a pressure surface arc is greater than a radius of a suction surface arc, a radius of an inner peripheral side arc is greater than a radius of an outer peripheral side arc, and a region of maximum thickness is located 40% to 60% from the inner peripheral side arc in the lengthwise direction. The blades are disposed such that the inner peripheral side arcs are positioned on an inner peripheral side of the support plate and the outer peripheral side arcs are positioned on an outer peripheral side of the support plate. A flow path width between the plurality of blades gradually decreases from the inner peripheral side toward the outer peripheral side of the support plate.

Cross flow fan

A crossflow fan includes a rotary impeller formed by curved blades. Each of the bladeshas an outer peripheral edgeclose to the centrifugal side of the impeller and an inner peripheral edgeclose to the rotation axis side of the impeller. A plurality of cutoutsare formed in the outer peripheral edgeand spaced apart at predetermined intervals. Dimplesfor changing a boundary layer from a laminar flow to a turbulent flow are formed in a negative pressure surfaceof each bladein the vicinity of the outer peripheral edgeto prevent the gas flowing around the bladefrom separating from the blade

Crossflow fan and air conditioner provided with same

A crossflow fan includes an impeller formed by plate-like blades. Each bladeis inclined such that the outer edgeis located on the leading side of the inner edgewith respect to the rotation direction of the impeller. The face of each bladethat is located on the leading side of the rotation direction forms a positive pressure surface, and a face located on the trailing side forms a negative pressure surface. Notchesare formed at the outer edgeof the blade. The notchesare arranged at predetermined intervals along the rotation axis of the impeller. A basic shape sectionis formed between each adjacent pair of the notches. The blade thickness Lin the vicinity of the bottomof each notchis smaller than the blade thickness of the basic shape sectionadjacent to the notch
