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 control method of the water storage type water heater comprises the following steps that in the water using state, the hot water temperature drop rate is obtained, and the time point of starting heating operation of a unit is dynamically adjusted according to the relation between the hot water temperature drop rate and the basic rate; when the hot water temperature drop rate exceeds the basic rate, the unit starts heating operation immediately; and when the hot water temperature drop rate does not exceed the basic rate, the unit starts heating operation after the water temperature drop value reaches a preset value. The invention aims to provide the control method of the water storage type water heater. The method can dynamically adjust the starting heating operation time point of the unit in a water using state, and can control the unit to start heating operation in advance, so that the risk of insufficient hot water consumption is reduced.
Description
Technical field[0001]The present invention relates to the field of water heaters, and more particularly to a water storage water heater, a controller, and a control method thereof.Background technique[0002]The existing water storage heat pump water heater can automatically operate in accordance with the hot water temperature set by the user. When the hot water temperature reaches the target value, the control unit stops the heating and running; the control unit starts heating when the temperature drop value reaches the preset value. Conventionally reserves the water-type heat pump water heater, the water temperature drop value of the unit is constant, when the amount of hot water is used in a short time, if the unit is still in accordance with the preset water temperature drop value control unit, there may be a unit start time lag, hot water Insufficient risk.Inventive content[0003]One of the objects of the present invention is to provide a water storage water heater control method ...
