AI Technical Summary

Technical Problem

Existing garment steamers cannot achieve dynamic matching between water volume and heating element power under different water quality or environment, resulting in unstable steam temperature, which may cause dripping or splattering, affecting ironing effect and reducing product reliability.

Method used

By controlling the duty cycle of the heating element relay and the wave dropping mode of the water pump, the temperature is detected in real time and the water supply level and heating power are automatically adjusted to ensure that the temperature is maintained within the preset range. The matching parameters are stored for direct recall later.

Benefits of technology

It achieves stable temperature output of the garment steamer under different working conditions, avoids dripping and splattering, improves ironing effect and safety, simplifies operation process and enhances product intelligence.

Abstract

The invention discloses an automatic control method for a water pump and a heating body of a garment steamer. A heating body relay is controlled to work at a preset duty ratio until the temperature reaches a preset preheating temperature. And after a working instruction is received, the water pump is controlled to supply water at the initial gear and the heating body is controlled to heat at the initial power, and then the heating power is gradually increased to the maximum power. And the system detects the duration of the temperature maintained in the preset temperature interval in real time. If the duration does not reach the preset threshold value, the heating power is reduced, the water supply gear of the water pump is increased, and then detection is repeated. And if the duration continuously reaches the preset threshold value for multiple times, determining the current water supply gear of the water pump as a matched water volume gear and storing the matched water volume gear. And during subsequent work, the stored matched water quantity gear is directly called to control water supply of the water pump. By automatically adjusting the matching relation between the water pump gear and the heating power, the phenomenon of water explosion or water dripping is effectively avoided, and the stability of the steam temperature is ensured.
