D) SUMMARY OF THE INVENTION
[0015] The various embodiments of the present invention provide a system and method for automated pressure-controlled lid for a cooking vessel.
[0016] According to one embodiment of the present invention, an automatic pressure-controlled lid lock mechanism for cooker vessels is provided. The system employs a lever system that reacts to the internal pressure levels within the cooker. In the default state, with no internal pressure, the lever stays in a position allowing the lid to open. As pressure builds up during cooking, the pressure indicator rises, causing the lever to move and lock the lid automatically. This ensures that the lid is not opened while the cooker is pressurized, thereby preventing accidents. Once the pressure subsides to a safe level, the mechanism automatically resets, allowing the lid to open. This process is entirely automatic, eliminating user error and enhancing safety and efficiency in the kitchen.

[0025] In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.
[0026] The various embodiments of the present invention provide a system and method for automated pressure-controlled lid for a cooking vessel.
[0027] According to one embodiment of the present invention, a system for an automated pressure-controlled lid for a cooking vessel includes a lid, handle, main body, lever mechanism, pressure indicator, and a spring system. This system ensures the lid locks or unlocks based on internal pressure levels, indicated by the pressure indicator, with the lever mechanism engaging or disengaging in response. The pressure indicator operates with a material or mechanism sensitive to internal pressure changes, facilitating proportional movement. The lever, connected to a locking mechanism, secures the lid during pressure build-up, with the spring system providing necessary force for the lever's movement back to its original position as pressure decreases. Designed for compatibility with various cooker types, this fully automated system enhances kitchen safety and efficiency by eliminating user error.
[0028] According to one embodiment of the present invention, a method for controlling a cooking vessel's lid via an automated pressure-controlled system involves sensing internal pressure changes, moving a lever to lock the lid as pressure rises, and maintaining this locked state until the pressure falls below a safe threshold, at which point the lever unlocks the lid. This process, aided by a spring system, ensures automatic adjustment of the lever mechanism in response to internal pressure variations. The pressure is detected through a sensitive material or mechanism, with the lever mechanism's movement directly linked to a locking pin or latch, ensuring the lid remains securely locked during high-pressure conditions. This method optimizes safety and efficiency by automating the pressure monitoring and lid locking process, significantly reducing the risk of user error.
[0029] According to one embodiment of the present invention, an automatic pressure-controlled lid lock mechanism for cooker vessels is provided. The system employs a lever system that reacts to the internal pressure levels within the cooker. In the default state, with no internal pressure, the lever stays in a position allowing the lid to open. As pressure builds up during cooking, the pressure indicator rises, causing the lever to move and lock the lid automatically. This ensures that the lid is not opened while the cooker is pressurized, thereby preventing accidents. Once the pressure subsides to a safe level, the mechanism automatically resets, allowing the lid to open. This process is entirely automatic, eliminating user error and enhancing safety and efficiency in the kitchen.
[0030] According to one embodiment of the present invention, a system for automated pressure-controlled lid for a cooker vessel comprises a pressure indicator, a lever mechanism and a spring system. The pressure indictor is configured to sense the internal pressure of the cooker vessel. The lever mechanism is designed to move in response to the pressure indicator's position, thereby locking or unlocking the lid. The spring system assists in the automatic movement of the lever based on pressure changes inside the cooker.
[0031] According to one embodiment of the present invention, a method for automated pressure-controlled lid for a cooker vessel includes the following steps: at the start of cooking, the lever is in an open position, allowing the lid to open; as pressure builds, the pressure indicator rises, moving the lever to a locked position; the lid remains locked as long as the pressure is above a preset safe threshold; and, once the pressure drops to a safe level, the lever returns to its original position, unlocking the lid.
[0032] According to one embodiment of the present invention, a pressure indicator is provided, which is configured for sensing the internal pressure of the cooker. It is typically constructed using a pressure-sensitive material or mechanism, such as a spring-loaded piston or a diaphragm, which moves proportionally to the internal pressure. When the pressure inside the cooker increases, this movement is translated into a mechanical action that triggers the locking mechanism.
[0033] According to one embodiment of the present invention, a lever mechanism is provided as the core component responsible for locking and unlocking the lid. It is designed to move in response to the pressure indicator's position. The lever mechanism is strategically placed so that when the pressure inside the cooker reaches a certain level, the lever shifts to a position that mechanically locks the lid, preventing it from being opened. The lever is connected to a locking pin or a latch that engages with the lid mechanically.
[0034] According to one embodiment of the present invention, a spring system is provided to aid the automatic movement of the lever. The spring system is calibrated to provide the necessary force to move the lever back to its original position once the pressure inside the cooker drops to a preset safe level. The spring system is typically designed to have a specific tension that correlates with the desired pressure thresholds, ensuring that the lid is only opened when it is safe.
[0035] FIG. 1 illustrates a system for automated pressure-controlled lid for a cooking vessel. The system includes a lid of pressure cooker vessel 103, a handle of pressure cooker lid 104, a main body of pressure cooker vessel 105, a lever mechanism 106, a pressure indicator 107, and a spring system 108.
[0036] FIG. 2 illustrates a side-view of a cooker assembly comprising a system for automated pressure-controlled lid.
[0037] FIG. 3a and 3b illustrate the top-views of a cooker assembly comprising a system for automated pressure-controlled lid.
[0038] FIG. 4 illustrates the side-view of the lever mechanism in closed condition.
[0039] FIG. 5a, 5b and 5c illustrate a plurality of views of the lever mechanism.
[0040] Although the embodiments herein are described with various specific embodiments, it will be obvious for a person skilled in the art to practice the embodiments herein with modifications.
