Instant heating and cooling type cold and hot water dispenser

The invention belongs to the technical field of household appliances and the technical field of refrigeration, and discloses an instant heating and cooling type cold and hot water dispenser. The instant heating and cooling type cold and hot water dispenser comprises a box, a refrigerating mechanism consists of a compressor (10), a condenser (17) and an evaporation coil (4), a fan (16), an ice water heat exchanger (3) and a stirring mechanism are located in a water tank (24), after running water is changed into ice water in an acceleration refrigeration manner via the refrigerating mechanism and the fan, the ice water is stirred by the stirring mechanism, the ice water and external running water are in heat exchange via the ice water heat exchanger, a heating mechanism consists of a quick heating device (5) and a flowmeter (27), a water pipe is connected with the flowmeter (27), after receiving data, the flowmeter (27) feeds back the data to a control box (6), and the quick heating device (5) begins to heat the water under actions of the control box (6). The instant heating and cooling type cold and hot water dispenser not only can realize instant heating and cooling functions, but also saves more electric energy, guarantees that ice water and hot water are supplied continuously, and meets the requirement of water drinking of multiple persons simultaneously.
