Cooking device for food

A cooking device for eggs, comprising:

• a base, having an inlet end and an outlet end, and an accommodating space formed between the inlet end and the outlet end, a transmission direction defined between the inlet end and the outlet end, wherein a direction from the inlet end to the outlet end is defined as a first transmission direction, and a direction from the outlet end to the inlet end is defined as a second transmission direction;
• a power unit, connected to the base, the power unit having a first driving member and a second driving member, the first driving member and the second driving member each having a plurality of rotation shafts, a plurality of sprockets, and a plurality of chains, the rotation shafts rotatably connected to the base and located in the accommodating space, the sprockets connected to the rotation shafts respectively, and the chains mounted around the sprockets, a first vertical height existing between one of the rotation shafts that is near the inlet end and a bottom portion of the base, a second vertical height existing between another rotation shaft that is near the outlet end and the bottom portion of the base, wherein the first vertical height is less than the second vertical height;
• and
• a multi-stage cooking unit, divided into an upper layer and a lower layer, the multi-stage cooking unit having a plurality of stoppers and at least one guideway, each of the stoppers pivotally connected to the plurality of chains of the second driving member of the power unit through a pivot joint rod, the stoppers of the upper layer driven by the second driving member to move towards the second transmission direction, the stoppers of the lower layer driven by the second driving member to move towards the first transmission direction, and the at least one guideway connected to the base, wherein the stoppers pivotally move to form a carrying spacing or a blanking spacing, the stoppers comprises a first stopper and a second stopper adjacent to the first stopper, the carrying spacing is between an end portion of the first stopper and the pivot joint rod of the second stopper, and is less than an outer diameter of eggs, the blanking spacing is between the pivot joint rod of the first stopper and the pivot joint rod of the second stopper, and is greater than the outer diameter of the eggs, and near the outlet end the stoppers pivotally move to output the cooked eggs;
• wherein heating eggs is achieved by boiled water poured into said accommodating space.
