Patent number: 10371409Abstract: A ceiling mounted ventilation fan includes a housing, a fan unit and lighting equipment installed in the housing. The housing including a first opening connected to an air outlet and communicating with a duct, and a second opening that communicates with a room interior. The lighting equipment includes an illumination unit, and a cover, that surrounds the illumination unit, and has a reflecting surface which reflects light from the illumination unit and guides the light into the room. The fan unit includes a fan and a casing positioned at a first position, spaced, from a second position that is above the second opening, the fan casing surrounding the fan and having an air inlet opening directed upwardly. Air is introduced through the second opening and through the air inlet into the fan unit and is discharged through into the duct by the fan unit.Type: GrantFiled: September 21, 2016Date of Patent: August 6, 2019Assignees: PANASONIC ECOLOGY SYSTEMS GUANGDONG CO., LTD., PANASONIC CORPORATIONInventors: Decong Yang, Qianhao Tan, Pingting Yang, Qiuqian Liang, Yannong Wu, Hitoshi Yoshikawa

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

Patent number: 8814513Abstract: A ceiling mounted ventilation fan with illumination capable of suppressing conduction of noise to inside of a room is provided. In the fan, a restriction member is provided for restricting passage of air between a lighting cover and a periphery of a lighting part, the lighting cover having a reflecting surface for reflecting light from the lighting part to lead the light to the inside of the room. A gap for air intake is formed between a lower end of the lighting cover and an edge of the indoor-side opening. Thus, air introduced into the main housing through the gap is discharged into the duct by the fan unit and conduction of noises produced by the fan unit to the room inside with the noise directivity enhanced in the lighting cover can be suppressed by the restriction member, so that conduction of noise to the room inside can be suppressed.Type: GrantFiled: September 29, 2011Date of Patent: August 26, 2014Assignees: Panasonic Ecology Systems Guangdong Co., Ltd., Panasonic CorporationInventors: Decong Yang, Qianhao Tan, Pingting Yang, Qiuqian Liang, Yannong Wu, Hitoshi Yoshikawa
