Description

Technical Field

[0001] The utility model relates to the field of cooking machines, in particular to a cooking device with a sealing structure. Background Art

[0002] Cooking robots are modern technological products. They not only have automatic stir-frying and frying functions, making the cooking process automated and interesting, but they also save a lot of labor and site costs, ensure the standardization of dish preparation and production, and are easy to quickly replicate and use in chain stores in the catering industry.

[0003] The stir-frying tools of existing cooking robots lack a sealing structure. When the spatula is used for stir-frying, ingredients, oil stains and water vapor can easily enter the driving mechanism, thus affecting the service life of the driving mechanism.

[0004] In addition, the stir-frying tools of existing cooking robots are generally driven by a centrifugal mechanism or a planetary gear mechanism to rotate for stirring and stir-frying. The spatula driven by the centrifugal mechanism rotates around the central axis of the pot in the pot, pushing the material in a circular motion, but cannot lift the material, and the flipping effect is poor. The spatula driven by the planetary gear mechanism is essentially still centrifugal stirring at different positions in the pot, and the flipping, breaking up, and mixing effects are not good. It is difficult for a traditional pot to complete a good stir-frying action simply by relying on a single stirring action, and centrifugal stirring and planetary stirring also make it difficult to coordinate with other actions to complete a good stir-frying function.
