Description

Technical Field

[0002] The cost of the catering industry, especially the cost of chefs, accounts for a considerable proportion of the total cost, which, to a certain extent, restricts the further improvement and expansion of the quality and service of the catering industry. At the same time, due to the high intensity of physical labor of chefs, they are prone to occupational diseases such as periarthritis of the shoulder and lumbar muscle strain after working for a long time. Therefore, a cooking machine that can reduce manpower, reduce labor costs, increase production speed, improve the working environment of chefs, save energy, and have consistent taste can effectively improve the above problems. Cooking machines are often used in fast food restaurants and restaurants for mass consumption. They can automatically stir-fry, fry, cook, deep-fry, stir-fry, simmer, steam, boil, bake, stew, and cook, easily realizing the automation and fun of the cooking process.

[0003] During the stir-frying process, the stirrer needs to continuously stir the ingredients in the pot through a stirring mechanism to ensure that the ingredients in the pot are evenly heated and mixed. The stirring mechanism usually includes a stirring shovel, a side scraper and a corresponding driving mechanism. The Chinese patent application number 201921326530.X discloses an automatic stirring cooking mechanism, in which the first driving member and the stirring member are connected through an external gear transmission assembly and a planetary mechanism. The overall structure is relatively poor in compactness, and the required installation space is relatively large, which will also affect the reliability and stability of the transmission.

[0004] To solve the above problems, the applicant provides a technical solution (application number: 2022222202157, name: a stirring mechanism for a cooking machine), which effectively improves the compactness of the overall structure and reduces the overall size and installation space by integrating the planetary mechanism with the output end of the stirring motor; however, this technical solution has the following disadvantages: its stirring shovel assembly is driven by one of the planetary gears, resulting in uneven force on multiple planetary gears, which not only easily causes broken teeth and tooth surface failure, but also makes the planetary gear easy to get stuck.

[0025] The output end of the stirring motor is processed into a sun gear 4, and a ring gear 16 is integrally formed at the position corresponding to the sun gear of the stirring motor body.
