对于一些重要的工作环境,几乎都要求室内的温度在一定范围内变化或者保持恒温。倘若工作人员进出房门而忘记把房门关上,这样室外的热空气或冷空气便流向室内,致使室内温度发生变化。本文所介绍的关门提醒器,在有人进出房门时,能及时发出“请随手关门”的语言声,房门被关闭后其语言声自动停止。 For some important working conditions, almost all indoor temperature changes within a certain range or keep constant temperature. If the staff member goes in and out of the room and forgets to close the door, hot or cold outdoor air will flow to the room, causing the indoor temperature to change. The door-closing reminder introduced in this article can promptly release the voice of “please close the door” when someone enters and exits the room. After the door is closed, the voice automatically stops.
