Title:
CLOTHES CARE MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/126715
Kind Code:
A1
Abstract:
Provided in the present application is a clothes care machine. According to the clothes care machine of the present application, a capacitor electrode is insulated and fixed in a boiler. The boiler and the capacitor electrode are separately electrically connected to a capacitance detection chip integrated on a control circuit board. In the foregoing manner, the boiler and the capacitor electrode form a capacitor device. The capacitance detection chip detects the capacitance of the capacitor device, and sends same to a processor integrated on the control circuit board. The processor controls the working state of a water supply mechanism according to the capacitance detected by the capacitance detection chip. In one embodiment, when the capacitance detected by the capacitance detection chip is higher than a capacitance threshold, the processor controls the water supply mechanism to inject water into the boiler. The clothes care machine of the embodiment of the present application has a simple structure. Furthermore, the dielectric constant of limescale is less than the dielectric constant of water, thus having a smaller effect on the capacitance of the boiler and the capacitor electrode without affecting a water level detection result, such that the working state of the clothes care machine of an embodiment in the present application is stable and reliable.
