Publication number: 20190017517Abstract: A centrifugal blower includes a stator housing. The stator housing includes a radial contact surface which makes contact with a casing in a radial direction, a circumferential contact surface which makes contact with the casing in a circumferential direction, and an axial contact surface which makes contact with the casing in an axial direction. With such configuration, it is possible to reduce the vibration of the blower by increasing a contact area between the casing and the stator housing. Further, the stator housing includes a heat dissipating surface. As a result, it is possible to efficiently dissipate the heat, which is generated from the stator, from the heat dissipating surface of the stator housing to the gas existing within the wind tunnel.Type: ApplicationFiled: September 17, 2018Publication date: January 17, 2019Inventor: Takuya TERAMOTO

Publication number: 20180363928Abstract: A heat exchanger, an axial-flow fan, a bell mouth, a fan motor, and a baffle plate are disposed in a casing of an outdoor unit. The casing includes a front panel provided with an air outlet, and a rear panel provided with an air inlet. The bell mouth and the baffle plate are disposed on an inner surface of the front panel. The bell mouth has a first opening opened toward the heat exchanger, and a second opening opened toward the air outlet. The baffle plate is disposed to incline from a predetermined position on the inner surface of the front panel toward where the bell mouth is disposed.Type: ApplicationFiled: January 25, 2016Publication date: December 20, 2018Inventors: Katsuyuki YAMAMOTO, Takuya TERAMOTO

Publication number: 20180306034Abstract: A fan is equipped with a boss, a first blade member, and a second blade member. The boss has: a first end and a second end in an axial direction; an inclined surface inclined, in a direction from the second end to the first end, toward an axial center extending in the axial direction; and an outer peripheral surface located between the inclined surface and the second end. The boss is rotatable about the axial center. The first blade member is connected to the outer peripheral surface of the boss. The second blade member is connected to at least one of the inclined surface or the outer peripheral surface located between the inclined surface and a connecting portion where the first blade member is connected to the outer peripheral surface.Type: ApplicationFiled: November 2, 2015Publication date: October 25, 2018Inventor: Takuya TERAMOTO

Patent number: 8870528Abstract: A ventilation fan arranged to reduce vibrations includes an impeller rotating around a center axis, a motor portion arranged to rotate the impeller, a motor supporting portion arranged to support the motor portion, and a housing arranged to accommodate the impeller and the motor portion. The motor supporting portion includes a substantially disk-shaped base portion, and a substantially cylindrical bearing holding portion axially extending with the center axis as the center. At least the base portion is made from resin. On the surface of the base portion, a plurality of recessed portions which are axially recessed are arranged in the form of a net, a staggered pitch, a grid, or a honeycomb. A flat portion of the base portion excluding the recessed portions does not have a continuous region extending in a straight line radially from the center of the base portion.Type: GrantFiled: February 28, 2012Date of Patent: October 28, 2014Assignee: Nidec CorporationInventors: Takuya Teramoto, Hiroyoshi Teshima
