The invention discloses an intelligent multifunctional all-in-one machine. The intelligent multifunctional all-in-one machine comprises a dish-washing machine with a high-temperature water storage tank, a refrigerator with a refrigerating chamber and an exhaust module arranged at the top of the all-in-one machine, the exhaust module usesthe heat energy generated by the high-temperature water storage tank and the cold energy generated by the refrigerating chamber and converts the heat energy generated by the high-temperature water storage tank and the cold energy generated by the refrigeratingchamber into hot air and cold air respectively to be blown to the outside of the all-in-one machine so as to realize the heating and refrigerating functions of an air conditioner, a human body sensorfor sensing whether a human body is close to the all-in-one machine or not is arranged on the front side of the all-in-one machine, a control unit of the all-in-one machine controls the strength degree of the hot air and the cold air according to signals sensed by the human body sensor, and the limitation problem that an existing refrigerator and air conditioner all-in-one machine is non-uniform in air supply and can only be used for refrigerating is solved; moreover, the human body sensor is arranged on the front side of the multifunctional all-in-one machine so that the air supply volume andthe air speed can be automatically reduced when the human body is close to the all-in-one machine; and the structure is simple, the cost is low, and the intelligent design provides more comfortable use experience for users.
