AI Technical Summary

Technical Problem

The bypass circuit of existing household ironing appliances is costly and not beautiful, and it is easy to inhale water when the appliance stops, affecting the next startup and operation efficiency.

Method used

A bypass circuit is designed to directly transport part of the water from the pump into the steam conduit, and control the flow of water and air through the valve disc and check valve, ensuring that a small part of the water flows through the bypass circuit during the pump operation, reducing suction The amount of water and provide ventilation as the container cools to prevent water from being respirated.

Benefits of technology

It reduces manufacturing costs, limits the amount of water inhalation when the appliance stops, improves the starting efficiency and ironing performance, reduces the impact of water suction, and optimizes the operation stability.
