Three-temperature heat pump water dispenser

Abstract

This utility model relates to a three-temperature heat pump water dispenser, comprising a reverse osmosis module, a preheating water tank, an ice water tank, and a heat pump subsystem. The reverse osmosis module is equipped with a direct drinking water outlet pipe, the end of which is connected to the bottom of the preheating water tank, the top of the ice water tank, and a room temperature water outlet via a first, second, and third pipe, respectively. The reverse osmosis module is connected to a pressure tank via a pipe. The bottom of the ice water tank is connected to the ice water outlet via a fifth pipe. A first, second, and third solenoid valve are respectively installed on the third, fourth, and fifth pipes. The heat pump subsystem includes a compressor, a condenser pipe, an expansion valve, and an evaporator pipe connected in sequence. The compressor's exhaust port and intake port are connected to the condenser pipe and evaporator pipe, respectively. The condenser pipe is located inside the preheating water tank, and the evaporator pipe is located inside the ice water tank. This design absorbs heat from the ice water tank through the evaporator, and the heat released by the condenser is used for preheating, thus improving energy efficiency.
