Referring to fig. 1, fig. 1 is a schematic block diagram of an embodiment of an anti-dry heating control device of an electric heating apparatus of the present invention.
The dry-heating prevention control device of the electric heating equipment of the embodiment includes an obtaining module 100, a comparing module 200, a judging module 300 and an alarm module 400.
Specifically, in this embodiment, the electric heating device is a water dispenser, an electric water heater, an electronic atomizer, or an electric kettle. The electric heating wire is used for heating the material to be atomized in the electronic atomizer. The heating wire is made of a material such as Ni200 or TA1 (that is, the material of the heating wire may be Ni200 or TA 1), and the resistance value thereof increases with the increase of temperature. When a power switch of the electronic atomizer is turned on, the power supply supplies power to the heating wire at rated output power. With the increase of the power supply time, the temperature of the electric heating wire is continuously increased, after the temperature reaches a proper temperature (namely the temperature of the electronic atomizer in normal operation), the temperature of the resistance wire is not increased any more, and the resistance value of the resistance wire is also kept unchanged after the initial resistance value is increased to a preset resistance value (namely the resistance value of the electric heating wire in proper temperature).
The obtaining module 100 may be a single chip microcomputer or the like, and is configured to monitor a resistance value of the heating wire in real time and record an actual time when the heating wire reaches a preset resistance value from an initial resistance value.
The comparison module 200 may be a single chip microcomputer, and is configured to compare the actual time with a preset dry-burning time to obtain a time difference. The preset dry-heating time is the time when the resistance wire is in the air with rated power and reaches the preset resistance value, and is stored in a memory module in the electric kettle in advance. The storage module is selected as a memory.
The determining module 300 may be a single chip microcomputer, and is configured to determine whether the time difference is within a preset threshold range.
The alarm module 400 includes a buzzer, an indicator light (such as a light emitting diode) and/or a display screen, and the like, and is configured to perform a dry-fire alarm prompt when the time difference is within a preset threshold range.
The dry-heating prevention control device in the embodiment compares actual time for the heating wire to reach the preset resistance value from the initial resistance value with preset dry-heating time, judges that the heating wire is in a dry-heating state when the difference value is within a preset threshold range, and gives an alarm to prompt so as to effectively prevent dry-heating.
