The invention provides a cooking range. The cooking range comprises a heat collection furnace, a feeding frame and a lock catch structure. The heat collection furnace comprises a heat collection ring and a heat collection plate, wherein the heat collection plate is mounted at the bottom of the heat collection ring, and a heat collection cavity is defined by the heat collection plate and the heat collection ring together; the feeding frame comprises a frame body and a sealed door, one end of the frame body is mounted on the heat collection ring, the frame body is communicated with the heat collection cavity, and a linkage portion is arranged on the side wall of the frame body; one side of the sealed door is mounted at the other end of the frame body, a clamping portion is arranged on one side edge of the sealed door, and the clamping portion comprises a clamping shaft; a lock catch structure comprises a rotating part and a clamping buckling piece, the rotating part is rotatably mounted on the linkage portion, the clamping buckling piece comprises a first clamping foot and a second clamping foot, and the clamping shaft is clamped between the first clamping foot and the second clamping foot so as to prevent the sealed door from rotating relative to the frame body. The first clamping foot can elastically deform to be separated from the clamping shaft when the rotating part rotates relative to the frame body. Through the lock catch structure, the sealed door is clamped, and therefore the sealed door seals the heat collection cavity in the direction of the feeding frame.
