Patent number: 11739957Abstract: A ventilation fan includes a body unit, which has a fan disposed in a body case and a fan controller operable to control an air volume of the fan. The ventilation fan also includes a sensor module having an indoor environment detecting sensor and a module controller operable to control a detecting operation of the indoor environment detecting sensor. The body unit has a module mount on which the sensor module is mounted and another sensor module can be mounted in place of the sensor module. The module mount is connected to the fan controller. The module controller outputs detection information obtained based on a detection result of the indoor environment detecting sensor to the fan controller, which in turn controls the air volume of the fan based on the detection information inputted thereto.Type: GrantFiled: February 22, 2023Date of Patent: August 29, 2023Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Hirosato Sakai, Hidenori Syougen, Nobuyuki Morimoto, Tsuraki Nakajima, Shingo Takenawa, Masahiro Yamaguchi, Kazuki Doumoto

Patent number: 10041496Abstract: Between the lower stage in respective phases of inverter circuit and the negative potential side, shunt resistors are inserted for respective phases. The potential differences across shunt resistors occurring by current flowing through shunt resistors are amplified by amplifier unit. From the output of amplifier unit, current detecting unit detects current of each phase flowing through motor formed by a sensorless brushless DC motor. Rotation detecting unit calculates the rotation speed and position of motor based on the current detected by current detecting unit. This structure makes it possible to directly detect solely the current flowing through the windings of motor. Therefore, it becomes possible to accurately detect the current of the motor windings, and the ventilation device can maintain the ventilation air volume from a small air volume to a large air volume always at a constant value.Type: GrantFiled: June 26, 2014Date of Patent: August 7, 2018Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Tsuraki Nakajima, Harumoto Itou, Masahiro Yamaguchi, Shingo Takenawa, Kazuki Doumoto, Teikyo Ueno
