Publication number: 20180087781Abstract: A range hood includes: fan unit (4) having a built-in fan; frame unit (3) connected to the fan unit; rectifier (5) disposed in a lower part of the frame unit; and communication module (7) mounted on mounting portion (6) of the frame unit. The communication module includes transmitting/receiving unit (11) and transmitting/receiving unit case (8). The communication module performs, via the transmitting/receiving unit, radio communication using radio waves with a central control unit that controls another ventilation apparatus or another air conditioning apparatus. The transmitting/receiving unit case includes case portion (9) covering the transmitting/receiving unit, and cover portion (10) connected to the case portion. The mounting portion is made of metal, has a box shape, and has opening (21) so that radio waves arrive at transmitting/receiving unit that is built-in the mounting portion. The cover portion is at least partially made of resin or glass.Type: ApplicationFiled: September 12, 2017Publication date: March 29, 2018Inventors: NORIHIKO HASEGAWA, NAOYUKI FUNADA

Patent number: 9534802Abstract: Ventilation device is mounted on inner wall in wind tunnel communicating between indoor and outdoor sides, having a ventilation louver. The ventilation louver includes a louver frame and a movable louver. Horizontal distance from position of gravity center of the movable louver to the inner wall is greater than horizontal distance from the movable louver shaft to the inner wall. A lever is disposed at a lower part of the louver frame to move in a left-right direction along bottom end face of the lower part of the louver frame. A connection element is provided to connect the movable louver with the lever between the movable louver and the louver frame, which is configured to be a slidable structure in the up-down direction, and transform the movement in the left-right direction of the lever to opening and closing movement of the movable louver around the movable louver shaft.Type: GrantFiled: June 18, 2012Date of Patent: January 3, 2017Assignees: Panasonic Ecology Systems Guangdong Co., Ltd., Panasonic CorporationInventors: Bodong Zhong, Min Long, Jiahan Hong, Shi Zhen, Norihiko Hasegawa, Ryuuma Yokoyama

Patent number: 9222695Abstract: A heat exchange ventilator includes a plurality of heat exchanger elements provided with a heat-exchanger exhaust airflow path and a heat-exchanger intake airflow path. Exhaust airflow and intake airflow are guided to pass through one of the plurality of heat exchanger elements, and the exhaust airflow and the intake airflow are switched to the next heat exchanger element in a sequential order when a state of the heat exchanger element comes to a predetermined condition set based on adverse influences of ice formation inside a heat-exchanger exhaust airflow path. The structure prevents the heat exchanger element from icing to avoid the adverse influences, thereby making it capable of exerting the fundamental heat exchanging and ventilating function continuously.Type: GrantFiled: May 14, 2008Date of Patent: December 29, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Norihiko Hasegawa, Hirotsugu Hirano
