Description

Technical Field

[0001] This utility model relates to the field of anti-dry burning technology, and in particular to an anti-dry burning alarm. Background Technology

[0002] Dry burning commonly occurs in various scenarios during cooking, such as: prolonged steaming or simmering of soup, where the heat continues to rise after all the moisture has evaporated due to negligence; frying in oil exceeding 290℃ without timely adjustment of heat or monitoring of the temperature; and improper placement of the cookware or poor contact with the stove's temperature sensor. These scenarios can all lead to dry burning due to uncontrolled temperature or operational errors. Dry burning poses risks to food safety, damage to cookware, fire hazards, and equipment wear and tear.

[0003] Early solutions for preventing dry-burning of kitchen cookware primarily used bimetallic thermostats, which rely on the difference in the coefficients of thermal expansion of metals to control the circuit. This method suffers from response delays and is prone to false alarms. Current solutions for preventing dry-burning of household kitchen cookware are mostly integrated into the gas stove, using thermal sensors to collect the temperature near the target. This approach is prone to false alarms and accidental gas shut-offs, and requires replacing the gas stove, resulting in high costs for users. Existing solutions also use portable dry-burning alarms, mostly placed on the stovetop. Due to their limited detection range, they primarily detect the bottom and sides of the cookware, making them highly susceptible to interference from open flames and false alarms. Furthermore, this method requires very close proximity to the target, causing the product's internal temperature to rise significantly, reducing its lifespan. Additionally, current technologies lack positioning lasers, making it impossible to determine if the target is in an optimal position. Utility Model Content
