Water dispenser and control method thereof

The invention relates to the technical field of drinking equipment, and provides a water dispenser and a control method thereof. The water dispenser comprises a heat storage module, a heating module, a pumping piece and a control module. The water inlet end of the heat storage module communicates with a water supply system, a parallel branch is arranged between the water inlet end and the water outlet end of the heat storage module, and the parallel branch can be selectively connected or disconnected; the water inlet end of the heating module communicates with the water outlet end of the heat storage module, and the water outlet end of the heating module selectively communicates with the heat storage module or the water outlet through the valve control part. The pumping piece is used for driving water flow to flow to the heating module through the heat storage module and the parallel branch; the control module is electrically connected with the pumping part, the parallel branch, the heating module and the valve control part. The water dispenser can enter the heat storage mode to work, heat storage is conducted on the heat storage module through hot water output by the heating module in the heat storage mode, and the equipment cost and energy consumption are reduced.
