Abstract

The invention provides a control method of a heat-pump water heater. The control method includes the following steps of acquiring a cold water temperature, an ambient temperature, the number of users, and water consumption of each user; automatically judging the water temperature according to the ambient temperature; calculating a reference heating temperature of the heat-pump water heater according to the number of the users, total water consumption of the users, the water temperature and the cold water temperature; judging whether the reference heating temperature is lower than the water temperature, arranging the water temperature as a heating temperature of the heat-pump water heater and controlling the heat-pump water heater to operate according to the heating temperature if the reference heating temperature is lower than the water temperature. The invention further provides the heat-pump water heater. According to the heat-pump water heater and the control method thereof, the heating temperature can be arranged according to the total water consumption of the users, the cold water temperature, and the ambient temperature, so that energy consumption can be saved.

Description

technical field [0001] The invention relates to the technical field of home appliance control, in particular to a heat pump water heater and a control method thereof. Background technique [0002] Customer controllers of existing heat pump water heaters are generally set by setting the temperature. The controller has a certain set temperature range, for example, the temperature range is 38-60°C, such as figure 1 shown, where pressing the down arrow Press the key to decrease the set temperature, and press the up key "▲" to increase the set temperature. [0003] This control method is simple to set, but it is not intuitive and energy-saving in actual use. There are mainly the following disadvantages: [0004] Customers are not sensitive to the set temperature value and cannot directly experience whether the set value is appropriate. If it is too high, it is wasteful, and if it is too low, the water is not enough. If you need a suitable temperature value, you can only get i...
