  • Publication number: 20200232671
    Abstract: A setting facilitation apparatus (1400) includes a keyword input reception section (1410), a control command selection section (1420), and a specific control registration section (1430) and is used to facilitate setting of specific control in a control system (1001) that controls a control device through sound inputs. The keyword input reception section (1410) receives an input of information corresponding to a keyword. The control command selection section (1420) displays a certain control command to the control device (1010, 1020) on an edit screen (G) and receives selection of the control command. The specific control registration section (1430) registers a keyword (K) input by the keyword input reception section (1410) and the control command selected by the control command selection section (1420) to a specific control (DB 1104T) while associating the keyword and the control command with each other.

  • Publication number: 20200126549
    Abstract: A management system (1090) includes an air conditioner (1062), a sound input unit (1064), an operation sound analyzing unit (1016), a first preprocessing unit (1011), a command extracting unit (1014), and a control unit (1017). The sound input unit (1064) is provided in a room where the air conditioner is provided and obtains sound data (SD). The operation sound analyzing unit (1016) analyzes the sound data by a predetermined analysis method so as to obtain a determination result (RE) regarding whether an abnormality exists in the air conditioner or details of the abnormality. The first preprocessing unit (1011) performs first preprocessing on the sound data. The command extracting unit (1014) extracts a command (CM) of a user from the sound data that has been subjected to the first preprocessing. The control unit (1017) controls the air conditioner on the basis of the command.

  • Patent number: 9638195
    Abstract: 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.

  • Publication number: 20150354584
    Abstract: A centrifugal fan includes a hub, a plurality of blades, and a shroud. The blades each have a curved part that is curved to incline toward a side on which air impinges when a connected end connected to an inwardly protruding portion of the shroud moves in a rotating direction of the centrifugal fan. The hub includes a hub-side diffuser ring that protrudes radially outward of the blades. The shroud includes a shroud-side diffuser ring that protrudes radially outward of the blades.

  • Publication number: 20150240645
    Abstract: A propeller fan includes a blade. The blade has a shape in which a peak outlet angle at a trailing edge thereof exists in an outer region of the blade that is located radially outer than the representative square mean radius position, and an another peak outlet angle at a trailing edge thereof exists in an inner region of the blade that is located radially inner than the representative square mean radius position.

  • Patent number: 9046110
    Abstract: A crossflow fan includes a rotary impeller formed by curved blades 42. Each of the blades 42 has an outer peripheral edge 43 close to the centrifugal side of the impeller and an inner peripheral edge 44 close to the rotation axis side of the impeller. A plurality of cutouts 45 are formed in the outer peripheral edge 43 and spaced apart at predetermined intervals. Dimples 48 for changing a boundary layer from a laminar flow to a turbulent flow are formed in a negative pressure surface 4q of each blade 42 in the vicinity of the outer peripheral edge 43 to prevent the gas flowing around the blade 42 from separating from the blade 42.

  • Patent number: 8596958
    Abstract: A crossflow fan includes an impeller formed by plate-like blades 42. Each blade 42 is inclined such that the outer edge 42a is located on the leading side of the inner edge 42d with respect to the rotation direction of the impeller 41. The face of each blade 42 that is located on the leading side of the rotation direction forms a positive pressure surface 42p, and a face located on the trailing side forms a negative pressure surface 42q. Notches 42b are formed at the outer edge 42a of the blade 42. The notches 42b are arranged at predetermined intervals along the rotation axis of the impeller. A basic shape section 42c is formed between each adjacent pair of the notches 42b. The blade thickness L2 in the vicinity of the bottom 42y of each notch 42b is smaller than the blade thickness of the basic shape section 42c adjacent to the notch 42b.
