Instant cold water outlet control method and device, water dispenser and storage medium

The invention discloses an instant cold water outlet control method and device, a water dispenser and a storage medium. The method comprises the steps that the temperature of water in a cold water outlet waterway is monitored, the temperature of water in the cold water outlet waterway is compared with the preset cold water temperature, and the on-off state of a light-emitting unit in the multifunctional control switch and the work of a water pumping device or a refrigerating device in the cold water outlet waterway are controlled according to the comparison result. By means of the method, the problem that cold water and hot water switching is tedious due to the fact that refrigeration and heating are integrated in one control system in an existing water dispenser can be solved, meanwhile, the problem that cold water outlet of the existing water dispenser cannot meet the cold water temperature requirement can be solved, reminding of the cold water state can be achieved, the cold water state is visualized, and
