Water level detection method and device, water heater and storage medium Technical Field The embodiment of the application relates to the technical field of water heaters, in particular to a water level detection method and device, a water heater and a storage medium. Background At present, a water level detector is usually placed in a water tank of a water heater, then the water level in the water tank is detected by the water level detector, namely, a resistor in the water level detector can form a conductive loop with contacted water, when the water reaches different positions of the water level detector, the water level detector can generate different voltage signals and convert the voltage signals into corresponding values, so that the purpose of detecting the water level is achieved. Since the conductivity of water is related to water quality (i.e., when the soluble solids (Total Dissolved Solids, TDS) in water are low), and the method for detecting the water level by using the water level detector mainly depends on the conductivity of water, the sensitivity detection mode of the water level detector, i.e., the high sensitivity detection mode and the low sensitivity detection mode, can be manually set according to the water quality conditions of different areas, so as to match the water quality conditions of different areas, and improve the water level detection accuracy of the water level detector. However, the above-mentioned manner of manually setting the sensitivity detection mode of the water level detector can only be selected within two preset sensitivity ranges (i.e., high sensitivity and low sensitivity), and cannot be accurately matched with the actual water quality condition, which results in low accuracy of water level detection. Disclosure of Invention The embodiment of the application provides a water level detection method, a water level detection device, a water heater and a storage medium, which realize a water level detection function and solve the problem that in the prior art, the accuracy of water level detection is low because the actual water quality condition cannot be matched accurately.
