Multi-zone washing machine
By setting a water seal structure at the exhaust port of the small cylinder and optimizing the exhaust pipe layout, the problem of foam overflow was solved, and a highly efficient drying effect without the need for small zone valves was achieved.

AI Technical Summary
In existing multi-zone washing machines, foam tends to overflow from the exhaust duct during the washing process, affecting usability.
The exhaust vent of the small drum is located near the bottom, and the distance from the exhaust vent to the bottom of the small drum is less than 1/4 of the diameter of the small drum. The washing water level is located below the exhaust vent to form a water seal and prevent foam from overflowing. At the same time, an inverted V-shaped exhaust pipe and a flat drying component are used to simplify the structure and improve drying efficiency.
It effectively avoids foam overflow, simplifies the structure, improves drying efficiency, and eliminates the need for small-zone valves.
