Refrigeration device having freeze-drying function

The utility model relates to a refrigerator device comprising a refrigerating chamber, a freezing chamber, and a freeze-drying chamber arranged between the refrigerating chamber and the freezing chamber. The loop of the refrigeration system of the refrigerator successively comprises a compressor, a condenser, an anti-dew pipe, a drying filter and a solenoid valve. The solenoid valve is provided with a first refrigerant outlet, a second refrigerant outlet and a third refrigerant outlet. The first refrigerant outlet is connected with the refrigerant inlet of a freezing evaporator through a first capillary. The second and third refrigerant outlets are connected with the refrigerant inlets of a refrigerating evaporator and a freeze-drying chamber evaporator respectively through a second capillary and a third capillary. The refrigerant outlets of the refrigerating evaporator and the freeze-drying chamber evaporator are connected in parallel with each other and then are connected with the refrigerant inlet of the freezing evaporator. The refrigerant outlet of the freezing evaporator is connected with the refrigerant backflow port of the compressor after passing through a liquid storage barrel. Due to the adoption of the technical proposal of the utility model, the refrigeration device having a freeze-drying function can realize the freeze-drying function besides the functions of an existing refrigerator and an existing freezer, so that loosened porous and dried substances can be obtained.
