Patent number: 6386966Abstract: In a blower unit for a vehicle air conditioner, an inside/outside air switching door opens an inside air introduction port and closes an outside air introduction port when an inside air introduction mode is set. Plural ribs for irregularly reflecting an air-blowing noise generated by a blower fan are provided on an inner surface of the inside/outside air switching door, and top ends of the ribs are arranged along a main flow of inside air introduced from the inside air introduction port during the inside air introduction mode. Thus, the blower unit effectively reduces a reflected noise on the inner surface of the inside/outside air switching door, and effectively prevents a disturbance noise of the main flow of inside air.Type: GrantFiled: September 5, 2000Date of Patent: May 14, 2002Assignee: Denso CorporationInventors: Kazutoshi Kuwayama, Manabu Miyata

Patent number: 6354169Abstract: In a vehicle air conditioner, inside air and outside air are switched by first and second inside/outside air switching doors. The first inside/outside air switching door is operated by a first door lever operatively linked with an inside/outside air operation member of an operation panel. On the other hand, the second inside/outside air switching door is operated by a second door lever which is operated by a mode operation lever operatively linked with a mode operation member of the operation panel, a temperature-adjustment operation lever operatively linked with a temperature-adjustment operation member of the operation panel, and an elastic force of a spring. When an air outlet mode except for a defroster mode is manually set by the mode operation member, and when maximum heating is manually set by the temperature-adjustment operation member, the second inside/outside air switching door is operated to an inside air introduction state by the second door lever.Type: GrantFiled: March 30, 2000Date of Patent: March 12, 2002Assignee: Denso CorporationInventors: Takashi Toyoshima, Kazushi Shikata, Kazutoshi Kuwayama

Patent number: 6220383Abstract: An electric power unit is composed of a secondary battery, a cooling fan, a fan motor and a case for the secondary battery, the cooling fan and the fan motor. The case has a partition for isolating the fan motor from the secondary battery and cooling fan. A magnetic joint is disposed between the motor and the cooling fan.Type: GrantFiled: September 8, 1998Date of Patent: April 24, 2001Assignees: Denso Corporation, Asmo Co., Ltd.Inventors: Toshihiko Muraki, Yuichi Shirota, Teruhiko Kameoka, Kazutoshi Kuwayama, Tetsuya Takechi, Hikaru Sugi, Tokuhisa Takeuchi, Mineo Yamaguchi, Yasushi Ueda, Hideyuki Takahashi

Patent number: 6030286Abstract: In a centrifugal blower in which the outer periphery of an intake opening is arranged outside of the inner edge of a main blade, a large number of sub blades are provided in the intake opening at a location corresponding to the main blade. The sub blades lead the secondary air flowing from an outside area of the intake opening to a rotating direction of a centrifugal multi blade fan. Thus, the secondary air flows from the sub blade to the main blade smoothly, thereby increasing a secondary air flow amount and reducing air flow noise.Type: GrantFiled: January 15, 1998Date of Patent: February 29, 2000Assignee: Denso CorporationInventors: Teruhiko Kameoka, Koji Ito, Kouji Matsunaga, Kazutoshi Kuwayama

Patent number: 5936321Abstract: A position of a second permanent magnet with respect to a first permanent magnet is defined by assembling a driving side support member, a thrust bearing, a spacing member, a radial bearing, and a driven side support member. The first and second permanent magnets are respectively held on the driving side support member and the driven side support member. Accordingly, variation of a magnetic gap between the first and second permanent magnets can be reduced. Variations in assembling the parts hardly affect the variation of the magnetic gap.Type: GrantFiled: May 29, 1998Date of Patent: August 10, 1999Assignee: Denso CorporationInventors: Teruhiko Kameoka, Kazutoshi Kuwayama, Hikaru Sugi

Patent number: 5876277Abstract: A deodorizing filter for adsorbing malodorous particles in air is disposed at a downstream air side of a circumferential wall of an inside/outside air switching rotary door which opens and closes inside and outside air intake ports. A gap having a predetermined distance is provided between the deodorizing filter and the circumferential wall of the rotary door. The deodorizing filter is rotated integrally with the rotary door. When the rotary door is rotated to open both the outside and inside air intake ports at their intermediately opened positions, the inside air flowing from the inside air intake port directly flows into an outlet side of an inside/outside air switching box, and the outside air introduced from the outside air intake port passes through the gap and the deodorizing filter and flows into the outlet side of the inside/outside air switching box.Type: GrantFiled: January 28, 1998Date of Patent: March 2, 1999Assignee: Denso CorporationInventors: Yukio Uemura, Manabu Miyata, Takuya Natsume, Kazushi Shikata, Hikaru Sugi, Teruhiko Kameoka, Kazutoshi Kuwayama, Yuichi Kajino, Takeshi Yoshinori

Patent number: 5813831Abstract: A bell-mouth ring is formed with a casing to be disposed proximately at an outer radial side of a shroud. The bell-mouth ring has a deflection wall surface for deflecting a flow of air blown out radially outwardly from the centrifugal multi-blade fan and further flowing radially inwardly toward the rotation axis along an inner wall surface of the casing, toward the driving means. In this way, it is possible to suppress air from flowing backward to a suction port through a gap between the shroud and the bell-mouth ring. Accordingly, it is possible to reduce the noise generated by an interference of the air sucked from the suction port with the air flowing backward or by the turbulence of the air flow which is generated in the gap.Type: GrantFiled: March 10, 1997Date of Patent: September 29, 1998Assignee: Denso CorporationInventors: Kouji Matsunaga, Koji Ito, Teruhiko Kameoka, Kazutoshi Kuwayama

Patent number: 5746577Abstract: An inner diameter (d.sub.2) of a centrifugal-type multiple-vane fan at a side where the motor is inserted (i.e., the insertion side) is larger than an inner diameter (d.sub.1) of the centrifugal-type multiple-vane fan at a side where the motor is not inserted (i.e., the non-insertion side), such that the ratio of a difference between an outer diameter (D) and the inner diameter (d.sub.2) of the centrifugal-type multiple-vane fan of the insertion side to a difference between the outer diameter (D) and the inner diameter (d.sub.1) of the centrifugal-type multiple-vane fan of the non-insertion side is in a range of 0.6-0.95. Thus, a centrifugal-type blower having the centrifugal-type multiple-vane fan can obtain a desired air volume while maintaining a small size of the centrifugal-type blower.Type: GrantFiled: February 11, 1997Date of Patent: May 5, 1998Assignee: Denso CorporationInventors: Koji Ito, Teruhiko Kameoka, Kouji Matsunaga, Kazutoshi Kuwayama
