a first electrical component disposed in at least one of the front surface of the cooktop and an interior of the cooktop;
a first suction port disposed in an upper portion of a front surface of the oven, the first suction port being positioned below the first electrical component;
a second suction port disposed in an upper portion of the front surface of the cooktop, the second suction port being positioned above the first electrical component;
a first cooling duct formed between an upper portion of the oven and the bottom surface of the cooktop and including:
a front portion configured to connect with the first suction port and
a communication port formed at a top surface of the first cooling duct;
an exhaust port disposed in a rear of the cooktop and configured to connect with a rear portion of the first cooling duct;
a second cooling duct formed above the first cooling duct, the second cooling duct formed by the cooktop itself, and including an outlet formed on the bottom surface of the cooktop;
a space provided between the bottom surface of the cooktop and the top surface of the first cooling duct;
