Description

Technical Field

[0001] This utility model belongs to the technical field of washing machine liquid level sensor, and specifically relates to a washing machine liquid level sensor and anti-corrosion module. Background Technology

[0002] Washing machines are essential household appliances that free up family members' hands. A liquid level sensor within the washing machine monitors the water level inside the drum, enhancing the machine's intelligence and preventing negative impacts from excessively low or high water levels. However, washing machine liquid level sensors are constantly exposed to a humid environment, which can gradually corrode them. Different detergents used for different types of laundry can also corrode the sensor due to their varying acidity or alkalinity. High temperatures are also common in some washing machines, and other stains such as oil on the clothes can further increase corrosion. Liquid level sensors typically consist of a probe and a main body, creating gaps at the connection. Commonly used internal liquid level sensors in washing machines lack proper sealing and corrosion protection, often being directly exposed. Insufficient sealing allows liquid to gradually seep into the sensor, affecting its internal electronic components. External corrosion also gradually corrodes the outer casing, ultimately impacting the sensor's performance over time.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
