AI Technical Summary
In the high-temperature and high-fume environment of the kitchen, the self-cleaning structure of existing integrated sinks cannot effectively remove grease, which can easily cause the drain pipe to become clogged, affecting the user experience and potentially causing hygiene and safety hazards.
By installing a steam generator and a pressure limiting structure between the water purification unit and the sewage pipe, high-temperature steam is generated using filtered water to perform targeted cleaning of the sewage pipe. The steam pressure is released after reaching a certain limit to improve the cleaning effect.
Effectively cleans the drain pipe, prevents blockage, improves user experience, extends the life of the steam generator, and ensures smooth drainage.
