The present invention relates to a storage amount detection technology field, and more particularly, to a storage amount detection method, a storage amount detection device, a cooking appliance, and a computer-readable storage medium.

In the prior art, when the material storage device stores the material, a storage amount detection function has been developed to improve the user's use experience, and specific operating principles of various storage amount detection methods are as follows.

(1) Optical sensors having different horizontal positions are installed on the inner wall of the receiving portion of the material storage device, the optical sensor detects the brightness value in the receiving portion, and the brightness value in the receiving portion detected by the optical sensor covered by the material is Since the brightness value in the housing portion lower and detected by the optical sensor not covered by the material is higher, the position of the trademark surface of the material is checked based on the inflection point of the brightness value.

(2) The installed storage amount detection module includes a driving member and an optical sensor installed on the outer wall of the receiving portion, and the optical sensor continuously moves between the upper and lower portions of the receiving portion, thereby corresponding to any horizontal position in the receiving portion. The brightness value can be continuously detected.
