Problems solved by technology
For conventional water storage type heat pump water heaters, the water temperature drop value of the unit is constant. When the hot water consumption is large in a short period of time, if the unit still controls the start-up time according to the preset water temperature drop value, there may be a delay in the start-up time of the unit, hot water insufficient risk

The invention relates to the technical field of water heaters, in particular to a water storage type water heater, a controller and a control method thereof. The storage water heater control method includes the following steps: in the state of water use, obtain the temperature drop rate of hot water, and dynamically adjust the time point when the unit starts heating operation according to the relationship between the temperature drop rate of hot water and the basic rate; When the water temperature drop rate exceeds the base rate, the unit starts heating operation immediately; when the hot water temperature drop rate does not exceed the base rate, the unit starts heating operation after the water temperature drop reaches the preset value. The purpose of the present invention is to provide a water storage water heater control method that dynamically adjusts the start-up and heating operation time of the unit in the water-using state. The control method can control the unit to start the heating operation in advance and reduce the risk of insufficient hot water consumption.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to a water storage type water heater, a controller and a control method thereof. Background technique [0002] The existing water storage type heat pump water heater can automatically operate according to the hot water temperature set by the user. When the hot water temperature reaches the target value, the control unit stops the heating operation; when the water temperature drop reaches the preset value, the control unit starts the heating operation. For conventional water storage type heat pump water heaters, the water temperature drop value of the unit is constant. When the hot water consumption is large in a short period of time, if the unit still controls the start-up time according to the preset water temperature drop value, there may be a delay in the start-up time of the unit, hot water risk of inadequacy. Contents of the invention [0003] One of the objectives of...
