Outer roller, water leakage monitoring method and device and clothes processing equipment

The invention discloses an outer roller, a water leakage monitoring method and device and clothes processing equipment. The water leakage monitoring method comprises the following steps: when the clothes processing equipment executes a washing program, acquiring an ultrasonic signal on an outer cylinder wall by utilizing ultrasonic monitoring equipment; and comparing the ultrasonic signal with a preset ultrasonic signal to judge whether the connection part between the front cylinder and the rear cylinder leaks water or not. Through the ultrasonic monitoring device, whether the outer cylinder of the clothes processing device leaks water or not in the large vibration process of washing, dewatering and the like is monitored, risks caused by water leakage are eliminated, and user safety is guaranteed. 本发明公开了一种外滚筒、漏水监测方法、装置和衣物处理设备。所述漏水监测方法包括：在衣物处理设备执行洗涤程序时，利用超声波监测设备获取外筒壁上的超声波信号；将超声波信号与预设超声波信号进行比对，以判断前筒和后筒之间连接部分是否漏水。本发明通过超声波监测设备，监测衣物处理设备在洗涤与脱水等振动较大过程中外筒是否出现漏水的问题，消除漏水导致的风险，保障用户安全。
