a cover which closes the opening portion while coupled to the accommodating tank, and has an air exhaust part communicating with the accommodating space; a vacuum pump which is provided in the housing; and a vacuum port which is configured to be switched between a first state in which the vacuum port is in close contact with the air exhaust part inside the container-accommodating chamber, and a second state in which the vacuum port is spaced apart from the air exhaust part, the vacuum port including an exhaust line for communicatively connecting the vacuum pump and the air exhaust part in the first state. ## Claims ### Claim 1 A food processor comprising: a housing comprising a container accommodating chamber, a door for opening and closing a lateral side of the container accommodating chamber, and a driver accommodating chamber; a containing tank put in the container accommodating chamber or taken out of the container accommodating chamber through the lateral side of the container accommodating chamber opened by the door, formed with an opening through which a food ingredient is put therein, and comprising an accommodating space formed to accommodate the food ingredient put through the opening and a processing member provided to be rotatable to process the food ingredient inside the accommodating space; a cover detachably coupled to the containing tank, closing the opening while being coupled to the containing tank, and comprising an exhausting portion formed to communicate with the accommodating space; a vacuum pump provided in the driver accommodating chamber; a vacuum port switched over between a first state to be in closed contact with the exhausting portion and a second state to be spaced apart from the exhausting portion in the container accommodating chamber, and connected to communicate with the vacuum pump and the exhausting portion in the first state; a cooling plate provided in a vertical wall partly defining the container accommodating chamber; and a cold energy generator provided in the driver accommodating chamber and transferring cold energy to the cooling plate. ### Claim 2 (depends on 1) The food processor of claim 1, wherein the vacuum port is switched over between the first state and the second state by interlocking with opened and closed states of the door. ### Claim 3 (depends on 2) The food processor of claim 2, wherein the vacuum port is switched over from the first state to the second state as the door opens the container accommodating chamber. ### Claim 4 (depends on 2) The food processor of claim 2, wherein the door does not close the container accommodating chamber unless the vacuum port is in the first state. ### Claim 5 (depends on 2) The food processor of claim 2, wherein the vacuum port is not maintained in the first state unless the door closes the container accommodating chamber. ### Claim 6 (depends on 1) The food processor of claim 1, wherein the lateral side of the container accommodating chamber comprises a curved surface, and the door is laterally opened and closed along the curved surface. ### Claim 7 (depends on 1) The food processor of claim 1, wherein the exhausting portion comprises a foreign matter trap to prevent foreign matter introduced into the exhausting portion from flowing into the vacuum port while the vacuum pump draws gas out of the accommodating space through the exhausting portion and the vacuum port. ### Claim 8 (depends on 1) The food processor of claim 1, further comprising: a magnet provided under the container accommodating chamber and providing magnetic force that affects the processing member; and a driving motor provided in the driver accommodating chamber and rotating the magnet. ### Claim 9 (depends on 1) The food processor of claim 1, further comprising a heat dissipation unit to discharge heat generated from the cold energy generator to an outside of the housing.
