Patent number: 8511832Abstract: A projector which includes a first exhaust fan discharging exhaust air from a light source lamp to exterior and a second exhaust fan discharging exhaust air from parts other than the light source lamp are arranged to be adjacent to each other. An end of the exhaust fan facing the other exhaust fan is moved to the inner side and the one exhaust fan is inclined to discharge air in an exhaust direction toward a direction along which air is discharged from the other exhaust fan. There is provided a cooling fan that blows air to an interior air blow outlet communicating with the interior of the light source lamp and exterior air blow outlets communicating with an outer surface to cool the light source lamp. The exterior air blow outlets are deviated from the center of the outer surface of the light source lamp.Type: GrantFiled: April 4, 2008Date of Patent: August 20, 2013Assignees: SANYO Electric Co., Ltd., Sanyo Technology Center (Shenzhen) Co., Ltd.Inventors: Wanjun Zheng, Yanyun Yan, Xiangdong Liang, Xiangfei Kong, Yun Wang, Xiaoling Mao, Yi Guan, Yanshan Huang, Toshihiro Saruwatari, Shoji Okazaki, Tadashi Renbutsu

Patent number: 8177372Abstract: This invention provide a projector apparatus enabled to lower its exhaust air temperature by adding only minor modifications to the existing structure, without altering its basic structure. The liquid crystal projector apparatus of the invention has a casing (1) for accommodating therein a light source (4), an optical system adapted to construct imaging light in response to a beam of light received from the light source, a power supply (9), and a cooling unit (6) mounted on the side wall of the casing (1) to cool the components in the casing. Provided on the inner wall of the casing is an air inspiration mechanism (16, 17, 18, 126) in association with the exhaust unit (6), whereby the exhaust unit (6) can inspire ambient air through the air inspiration mechanism to lower the temperature of the air to be expired from the exhaust unit.Type: GrantFiled: August 23, 2007Date of Patent: May 15, 2012Assignee: SANYO Electric Co., Ltd.Inventors: Wanjun Zheng, Toshihiro Saruwatari, Xianglin Zhang
