Large-flow instant heating type water dispenser device

The utility model discloses a large-flow instant heating type water dispenser device. The disinfection container is positioned and placed behind the water dispenser body; the output end of the water pump is communicated with the water inlet end of the instant heater through the lower chamber, and the water outlet end of the instant heater is communicated with the upper chamber through the bypass pipeline and the first control valve; a heat exchange piece is arranged between the lower chamber and the upper chamber; thus, during use, hot water can be controlled to be injected into the upper cavity firstly so that cold water flowing through the lower cavity can be subjected to heat exchange preheating through the heat exchange piece, then high-temperature water can be obtained more quickly when the hot water passes through the instant heater, substantive features and progress are achieved, and large-flow hot water output of a subsequent water outlet faucet is facilitated; besides, the upper connector of the oute
