Patent number: 9476608Abstract: The ceiling mounted ventilation fan with illumination employs a configuration in which a second opening for guiding light from an illumination unit into the room is formed in a lower part of a main housing and in which a air inlet on a fan casing of a fan unit is provided so as to open toward upper part of the main housing. Thus the air inlet of the fan unit opens in a direction opposite to the second opening communicating with inside of the room. As a result, sounds such as operation noises from the fan unit that are transmitted to outside of the fan unit chiefly through the air inlet can be made to resist being transmitted through the second opening into the room, so that the noises can be reduced.Type: GrantFiled: March 23, 2012Date of Patent: October 25, 2016Assignees: PANASONIC ECOLOGY SYSTEMS GUANGDONG CO., LTD., PANASONIC CORPORATIONInventors: Decong Yang, Qianhao Tan, Pingting Yang, Qiuqian Liang, Yannong Wu, Hitoshi Yoshikawa
