Cooking appliance and control method therefor

A cooking appliance, comprising:

• a main body;
• a cooking chamber provided inside the main body to be opened on one side and including a plurality of supports supporting a position of a rack on which cooking material is placed;
• a camera module provided on the cooking chamber to estimate the position of the rack on which the cooking material is placed and including a camera configured to generate a captured image by capturing the position of the rack on which the cooking material inside the cooking chamber is placed;
• and
• a controller configured to control the camera module,
• wherein the controller estimates the position of the rack on which the cooking material is placed based on image recognition using the captured image and sets at least one of an angle of view or a focus of the camera according to the estimated position of the rack,
• wherein the camera comprises:
• a sensor unit for capturing the captured image inside the cooking chamber;
• a fixing plate to which the sensor unit is fixed;
• magnets positioned at both ends of the fixing plate;
• a lens movably provided in a position opposite the sensor unit and configured to adjust a capture area and focus;
• and
• coils provided at both ends of the lens, and
• wherein a relative position of the lens with respect to the magnets is adjusted by the coils, thereby changing the capture area and focus.

A cooking appliance, comprising:

• a main body;
• a cooking chamber provided inside the main body to be opened on one side and including a plurality of supports supporting a position of a rack on which a cooking material is placed;
• a camera module provided in an electrical compartment, spatially separated from the cooking chamber such that heat inside of the cooking chamber is not transferred, to estimate the position of the rack on which the cooking material is placed and including a camera configured to generate a captured image by capturing the position of the rack on which the cooking material inside the cooking chamber is placed;
• and
• a cooling fan disposed on one side of the camera module and configured to cool the camera module by drawing in external air,
• wherein the camera comprises:
• a sensor unit for capturing the captured image inside the cooking chamber;
• a fixing plate to which the sensor unit is fixed;
• magnets positioned at both ends of the fixing plate;
• a lens movably provided in a position opposite the sensor unit and configured to adjust a capture area and focus;
• and
• coils provided at both ends of the lens, and
• wherein a relative position of the lens with respect to the magnets is adjusted by the coils, thereby changing the capture area and focus.
