Description

An Automatic Lid Handling System for An Automated Cooking Device and Method OperationDESCRIPTION:Field of the invention:

[0001] The present disclosure generally relates to the technical field of automated food preparation systems, in specific, relates to an automatic lid handling system for an automated cooking device that enhances versatility, safety, and convenience by seamlessly switching between pressure-cooking and regular lids, enabling the automated cooking device to perform precise pressure cooking, simmering, and steaming.Background of the invention:

[0002] Automated cooking devices have revolutionized modern kitchens by integrating advanced features such as programmable controls, temperature regulation, and automated stirring to enhance cooking efficiency and convenience. These devices streamline meal preparation, ensuring precision and consistency. However, many existing automated cooking systems lack a flexible and adaptive lid-handling mechanism, restricting their ability to perform multiple cooking techniques, such as pressure cooking, simmering, and steaming, without manual intervention.

[0003] Cooking methods require different lid configurations pressure cooking demands an airtight seal to build and maintain pressure, while simmering and steaming need a controlled venting system to regulate heat and moisture. Current automated cooking devices often require users to manually remove, replace, or secure different lids based on the cooking method, making the process cumbersome, inefficient, and potentially hazardous due to high-temperature conditions.

[0004] Some prior art solutions attempt to address this limitation by incorporating automated lid-handling mechanisms. For instance, US9723948B2 discloses a wok lid control apparatus applicable in a fully automated cooking machine. This system utilizes a linear motor-driven mechanism to lift and lower a wok lid, allowing automated opening and closing. When receiving a close-lid command, the linear motor moves downward to seal thewok, and upon an open-lid command, it lifts the lid away from the wok's opening. While this mechanism provides a basic automated lid-handling system, it is limited in several ways.

[0005] The wok lid control system in US9723948B2 is specifically designed for wok-style cooking and lacks adaptability for multiple cooking techniques such as pressure cooking or steaming. It does not provide a seamless transition between different lid types, limiting its applicability in multi-functional automated cooking devices. Additionally, the linear motor mechanism focuses only on vertical lid movement and does not accommodate real-time lid adjustments based on pressure or cooking phase, reducing its effectiveness in optimizing cooking performance

[0006] By addressing all the above-mentioned problems, there is a need for an automatic lid-handling system for an automated cooking device that enhances versatility, safety, and convenience by seamlessly switching between pressure-cooking and regular lids, enabling the automated cooking device to perform precise pressure cooking, simmering, and steaming. There is also a need for an automatic lid handling system that enhances the user convenience by eliminating the need for manual lid placement and removal, reducing user effort and streamlining the cooking process, making the automated cooking device accessible and user-friendly for individuals of all skill levels.

[0007] There is also a need for an automatic lid handling system that optimizes food quality by allowing seamless switching between airtight pressure cooking and regular cooking with steam release, helping users preserve flavors, retain moisture, and achieve the desired texture for a variety of dishes. There is also a need for an automatic lid-handling system that enhances cooking efficiency by automating lid operations, reducing delays, and ensuring consistent results, thereby saving time and eliminating the need for constant user monitoring. Further, there is also a need for an automatic lid handling system that reduces operational complexity through an intuitive design and automation, simplifying the learning curve for the users and allowing effortless operation without compromising performance or safety.Objectives of the invention:

[0082] According to one example embodiment of the invention, FIG. 10 refers to the schematic view of the automatic lid handling system 100 upon moving the drive shaft 124 from the second position to the first position. In one embodiment herein, the holding member 148 is deactivated to securely release the pressure-cooking lid 152 upon locking the pressure-cooking lid 152 with the cooking vessel 12 of the automated cooking device 10. In one embodiment herein, the secondary driving unit 134 is rotated in the clockwise direction to enable the holding member 148 to rotate and move linearly in an upward direction upon deactivating the holding member 148, thereby moving the holding member 148 to the rest position.

[0083] The primary driving unit 108 is activated to rotate in the clockwise direction to move the drive shaft 124 linearly along the vertical axis via the sector gear 114 and the gear member 112. So, the drive shaft 124 along with the pressure-cooking lid 152 is moved linearly along the horizontal axis away from the cooking vessel 12 of the automated cooking device 10 upon rotating the primary driving unit 108 in the clockwise direction. So, the drive shaft 124 is moved from the second position to the first position upon locking the pressure-cooking lid 152 on the cooking vessel 12.

[0084] In one embodiment herein, the automated cooking device 10 initiates the pressure cooking process upon moving the drive shaft 124 from the second position to the first position. In one embodiment herein, the automatic lid handling system 100 repeats the same steps to securely release the pressure-cooking lid 152 from the cocking vessel 12 of the automated cooking device 10 upon performing the cooking process.

[0085] According to another example embodiment of the invention, FIG. 11 refers to a flowchart 1100 of a method for operating an automatic lid handling system 100. At step 1102, the user secures the automatic lid handling system 100 to the support stand 11 of the automated cooking device 10 using the support frame 102. At step 1104, the support frame 102 enables the electrical connection with the automated cooking device 10 via the one or more electrical contacts 107 of each of the pair of arms 106, thereby supplying electrical power to the automatic lid handling system 100. At step 1106, the holding member 148 of the automatic lid handling system 100 is activated to securely hold at least one lid (152, 154) upon receiving the electrical power. At step 1108, the primary driving unit 108 is activated to move the drive shaft 124 from the first position to the second position through the guideway 120 of the mounting bracket 118 via the sector gear 114 and the gear member 112.

[0086] At step 1110, the secondary driving unit 134 is activated to rotate in at least one direction upon moving the drive shaft 124 from the first position to the second position, thereby allowing the holding member 148 to lock the lid (152, 154) with the cooking vessel 12. At step 1112, the holding member 148 is deactivated to securely release the lid (152, 154) upon locking the lid (152, 154) with the cooking vessel 12 of the automated cooking device 10. At step 1114, the primary driving unit 108 is activated to move the drive shaft 124 to move from the second position and the first position through the guideway 120 of the mounting bracket 118 via the sector gear 114 and the gear member 112.
