电器设备用选装装置以及电器设备
Abstract:
一种电器设备用选装装置，具备检测有无来自电器设备的排气的空气流传感器、以及根据其检测信号控制的电动风扇，即使选装装置的电动风扇在动作中，也能够充分减小其空气流的影响而利用空气流传感器正确地检测有无来自电器设备的排气。选装装置安装于内置有排气用风扇(22)的电器设备的排气口(9)，具备：管道(15)，其引导来自排气口(9)的排气；电动风扇(24)，其抽吸流经管道(15)的排气并将其向大气中排出；以及空气流传感器(25)，其检测有无来自电器设备的排气；空气流传感器(25)具备空气流路，该空气流路具有朝向排气开口的排气进入口(34)和在管道(15)之外连通于大气的出口(26b)，该空气流路与管道(15)的内部的其他部分被分隔壁(14)隔开。另外，选装装置具备将被电动风扇(24)抽吸的排气中的微粒子捕获的HEPA过滤器(23)，通过HEPA过滤器(23)净化后的空气从管道(15)的排气口(16)向大气中排出。
Abstract(English):

An optional device is for an electrical machine. The electrical machine includes an exhaust fan and an exhaust port on which the optional device is mounted. The optional device includes a duct, an electric fan, and an air flow sensor. Through the duct, an exhaust gas from the exhaust port is guided. The electric fan draws in the exhaust gas flowing through the duct and discharges the exhaust gas into an atmosphere. The air flow sensor detects presence or absence of the exhaust gas flowing from the electrical machine. The air flow sensor includes an air path partitioned from an inside of the duct by a partition wall. The air path includes an exhaust gas and an exit port. The exhaust gas intake port includes an opening facing the exhaust gas. The exit port communicates with the atmosphere at a position outside the duct.
