Abstract

The embodiment of the invention discloses a determining method for the heating time of a water heater and the water heater. The determining method comprises the steps: obtaining a refrigerating capacity rated parameter and input power rated parameter of a compressor in a unit of the water heater, evaporation temperature and condensation temperature of the unit; and water inlet temperature, preset upper limit temperature and water quality of the water tank of the water heater when the water heater starts to heat; determining the unit heating capacity of the water heater according to the refrigerating capacity rated parameter and input power rated parameter of the compressor in the unit and the evaporation temperature and condensation temperature of the unit; determining the heating capacity needed for heating the water heater to the preset target temperature according to the water inlet temperature of the water tank, the preset upper limit temperature and the water quality of the water tank; and determining the ratio of the needed heating capacity to the unit heating capacity according to the unit heating capacity and the needed heating capacity, and making the ratio serve as the heating time of the water heater. According to the determining method for the heating time of the water heater and the water heater provided by the embodiment of the invention, the reliability of determining the heating time of the water heater can be improved.

Description

technical field [0001] Embodiments of the present invention relate to water heater technology, and in particular to a method for determining heating time of a water heater and the water heater. Background technique [0002] In heat pump water heaters, water heaters such as heat pump water heaters are also more and more widely used. Because when the water heater is heating, the user can only see the unit is running, and the water temperature of the water tank is rising with time, but the user cannot know the current water temperature of the heat pump water heater. How long does it take to heat to the target set water temperature, which increases the time for the user to constantly check the water heater, resulting in a great waste of time. Therefore, for the convenience of users, the water heater needs to determine the heating time and display the heating time. [0003] At present, the existing method for determining the heating time of the water heater is usually to determi...
