Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically to a heating device for preventing dry burning. Background Technology

[0002] In many heating applications, such as heating reactions in laboratories, heating processes in industrial production, and the use of appliances like electric kettles and steamers in daily life, there are safety hazards and equipment damage caused by the liquid boiling dry. Therefore, some heating devices that prevent dry burning have appeared on the market.

[0003] For example, utility model patent CN207784940U discloses an anti-dry-burning heating device, which includes a heater, a water storage tank, and a controller for controlling the heater's heating. The bottom of the water storage tank has an outlet pipe connected to the heater's inlet, and the lower part of the water storage tank has a lower electrode level switch. When submerged in water, the lower electrode level switch is in a conductive state and sends a signal to the controller. The controller then controls the heater to heat according to the received signal. This anti-dry-burning heating device controls the water level in the storage tank by switching the electrode level switch on and off, and controls whether the heater heats based on the water level, effectively solving the problem of heater dry-burning.

[0004] The anti-dry-boil heating device provided by the aforementioned patent mainly controls the water level inside the water tank through an electrode level switch. However, this method is not suitable for heaters that heat kettles, because the electrode level switch cannot determine the water level inside the kettle.

[0039] Working principle: During use, insert the water suction tube 47 into the water storage container. Then, set the alarm threshold according to the weight of the kettle; the alarm threshold must not be less than the weight of the kettle. Next, place the kettle under the faucet 13 to fill it with water. After filling, place the kettle in the heating zone 11 and start heating. The water in the kettle is heated by the electromagnetic heating coil 51. When the water level in the kettle is too low, causing the kettle's weight to fall below the set threshold, the alarm module will be triggered, emitting an alarm sound to remind the user to add water immediately to prevent the kettle from boiling dry. The alarm module can also be connected to the switch on the main unit 1; when triggered, the switch will automatically turn off.

[0040] In summary, compared with the prior art, this application, by setting a pressure sensor in the boiling area of ​​the water boiler, can detect the weight of the kettle in real time. When the weight of the kettle is too low, an alarm module will be triggered to prompt the user to add water. This can effectively prevent the water inside the kettle from boiling dry.
