EVAPORATED FUEL TREATMENT DEVICE

PROBLEM TO BE SOLVED: To surely execute a purge process of a canister, without using, for example the negative pressure in an internal combustion engine. SOLUTION: An evaporated fuel treatment device includes an air conditioning system (500) having a refrigerant circulation circuit (500a) circulating refrigerant, a canister (400) adsorbing evaporated fuel produced in a fuel tank (300) storing fuel, refrigerant introduction means (610, 611) introducing refrigerant to the canister from the refrigerant circulation circuit, a refrigerant return means (620) returning the refrigerant introduced to the canister by the refrigerant introduction means together with the evaporated fuel removed from the canister by the introduced refrigerant to the refrigerant circulation circuit as mixture, and fuel recirculation means (630, 640) liquefying the evaporated fuel contained in the mixture returned to the refrigerant circulation circuit by the refrigerant return means and recirculating the same to the fuel tank.
