The invention discloses a method for detecting the position of a water tank temperature sensing bag. The method comprising the following steps: acquiring a detection temperature of the water tank temperature sensing bag T2; acquiring the external environment temperature T1; when the difference value between the T1 and the T2 is not larger than the value of preset temperature delta T, acquiring the temperature of the water outlet side of the water tank T3, and when T2 is lower than T3, the position of the temperature sensing bag of the water tank is abnormal; or acquiring the temperature of the water inlet side of the water tank T4, and when T2 is higher than T4, the position of the temperature sensing bag of the water tank is abnormal; or acquiring the temperature of the water outlet side of the water tank T3 and the temperature of the water inlet side of the water tank T4, when T2 is lower than T3 or T2 is higher than T4, the position of the temperature sensing bag of the water tank is abnormal. According to the detection steps, whether the position of the water tank temperature sensing bag is abnormal or not can be judged, an abnormal halt of a water heater is prevented, and normal use is guaranteed. The invention further discloses the water heater and a device for detecting the position of the water tank temperature sensing bag thereof.
Description
technical field [0001] The invention relates to the technical field of air energy water heaters, in particular to a water heater and a detection device and method for calibrating the position of a temperature sensor in a water tank. Background technique [0002] With the country's emphasis on environmental protection, air-energy water heaters are more widely used in places such as heating and hot water. At the same time, users have put forward higher requirements for energy-saving and reliability of air-energy water heaters. [0003] Most heat pump water heaters use the water tank temperature sensing package to detect the temperature of the water tank in real time, and start and stop the unit by collecting the temperature of the water tank. During the use of the unit, due to improper installation or use, the position of the temperature sensor of the water tank will be abnormal, resulting in the failure of the unit to work normally. [0004] Therefore, providing a detection ...
