Abstract

Provided are a water heater pipeline anti-freezing control method and system and a water heater. The method includes acquiring environment temperature and water temperature and water level of a water tank of the water heater; comparing the environment temperature and the preset environment temperature; when the environment temperature is lower than the preset environment temperature, executing the circulation heating water producing mode where water in a water inlet pipe and a water outlet pipe of the water heater flows in a circulation mode according to the water temperature and the water level of the water tank of the water heater; when the water heater is applied under the condition that the environment temperature is lower than the preset environment temperature, entering the circulation heating water producing mode enabling the water in the water inlet pipe and the water outlet pipe of the water heater to flow in the circulation mode. Flowing water passes through both the cold water inlet pipe and the circulation water inlet pipe of the water heater, the requirement for hot water usage can be met, and the pipeline has no freezing risks.

Description

technical field [0001] The invention belongs to the field of intelligent water heaters, and in particular relates to a water heater pipeline antifreeze control method, system and water heater. Background technique [0002] At present, heat pump hot water units are affected by the temperature, which makes some areas unusable. Especially in the area north of the Yangtze River, where the temperature is below 0°C in winter, the water pipes of the heat pump water heater unit are prone to freezing or even cracking. Especially the heat pump hot water unit with direct heating water production function and circulation heat preservation function, which has direct heating water production pipeline, water outlet pipeline and circulating water pipeline, wherein the direct heating water production pipe is connected to tap water pipe, circulating water inlet pipe and water outlet pipe Connect with the external water storage tank. When the unit is in the direct heating water production fu...
