Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of anti-dry burning, and particularly relates to an anti-dry burning alarm device. Background Art
[0002] Dry burning usually occurs in various scenarios during cooking and boiling processes. For example, during long-term steaming or soup cooking, due to negligence, the fire is not turned off in time, and continuous heating still occurs after the water has completely evaporated; during the frying process, the oil temperature exceeds 290°C and the firepower is not adjusted or the temperature is not monitored in time; the cookware is not placed correctly or has poor contact with the temperature sensing probe of the cooking appliance. These scenarios may all cause dry burning due to temperature out of control or operational errors. Dry burning can cause problems such as food safety risks, cookware damage, fire hazards, and equipment wear.
[0003] In the early stage, the solution to prevent dry burning of kitchen cookware mainly relied on a bimetallic thermostat, which achieved circuit on / off through the difference in the coefficient of thermal expansion of metals. This method has problems such as response delay and false alarms. Currently, the existing solutions to prevent dry burning of household kitchen cookware are basically integrated on gas stoves, and the detection principle is also to use a thermal sensor to collect the temperature near the detection target. This solution is prone to false alarms and accidental fire extinguishing, and the use of such products requires replacing the gas stove, resulting in a relatively high cost for users. There are also existing mobile anti-dry burning alarm devices to prevent dry burning. Most of their installation methods are to place them on the stove top. Affected by their detection dead zones, the detection targets are mainly the bottom and side of the cookware, and they are extremely vulnerable to interference from open flames, resulting in false alarms; and this solution requires being very close to the detection target, and the temperature of the product body will also increase accordingly, resulting in extremely high internal temperature of the product and reducing the service life of the product. In addition, in the prior art, such products do not have a positioning laser and cannot determine whether the detection target is in the best position. Summary of the Invention
[0004] To solve the above problems, the present invention provides an anti-dry burning alarm device, which is based on infrared thermal radiation and determines whether dry burning occurs to the cookware by collecting the temperature change within the target range.
