AI Technical Summary

Technical Problem

Traditional washing machines lack intelligent monitoring functions to check whether clothes have been removed and provide reminders. Their user interface design is also unreasonable, leading to problems such as clothes remaining and breeding bacteria, as well as difficulties in operation for users.

Method used

Design a laundry assistance device that integrates an ultrasonic sensor and a main controller. The device uses an audio acquisition module to determine when the washing machine has finished washing and issues a reminder if the clothes are not removed within a specified time. The ultrasonic sensor detects when the user approaches and, in conjunction with a peristaltic pump, enables precise addition of laundry detergent. The device is also equipped with voice interaction and a visual operation interface.

Benefits of technology

It effectively prevents clothes from accumulating bacteria, improves user convenience, provides reminders for removing clothes and allows for precise addition of laundry detergent, thus enhancing the user experience.
