Title
(ZH) 厨房用双监视器型电视门口对讲机设备及其操作方法
Abstract
(ZH)

本发明提供厨房用双监视器型电视门口对讲机设备及其操作方法,其具有电视、收音机和门口对讲机功能,包括:主体面板,第一监视器在主体面板的前表面上显示图像;辅助面板,其铰接到主体面板的底表面而可折叠和转动,第二监视器在辅助面板的前表面上显示图像;及重力定位传感器,其检测辅助面板的转动位置,根据检测到的转动位置控制对第二监视器的电源供应。根据该设备及操作方法,即使在安装在主体面板底表面上的可折叠的第二监视器水平折叠在主体面板下方时,仍能够通过安装在主体面板前表面的第一监视器及时查看用于显示访问者图像的门口对讲机图像,由此不仅提高了便利性,且消除了第二监视器所要占用的空间,于是提高了空间使用率。
