Abstract
The utility model relates to a fast heating device of an electric heater, which comprises a shell. The fast heating device is characterized in that a working circuit thereof consists of a power supply rectification circuit and a filter circuit with serial connection of a thermistor and a capacitor, wherein the filter circuit is connected with the output end of the rectification circuit in parallel, all components are arranged in the shell, and input connection ends and output connection ends are led out of the shell. When the fast heating device is used, the electric heater is connected with the output end of the device, and during the early period of electric heating, the resistance of the thermistor is low, the time constant of the filter circuit is large, the filter efficiency reaches the maximum, the voltage of the output end rapidly rises to the maximum, and the electric heat rapidly heats. When the temperature rises to a certain value, the value of the resistance of the thermistor is increased due to the charge/discharge current of the capacitor, thereby reducing the filter efficiency, and the voltage on the two ends of the heater can be maintained stable after being slowly reduced to a certain value.
Description
Technical field
The utility model relates to a kind of appurtenances of electric heater, particularly a kind of electric heater device for quickly elevating temperature.
Background technology
When it was cold, particularly winter was slow as electrical heated appliance programming rates such as electric iron, electric heaters, influenced work, quality of life.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and a kind of electric heater device for quickly elevating temperature that improves programming rate and keep temperature stabilization is provided.
The purpose of this utility model is achieved in that a kind of electric heater device for quickly elevating temperature, comprise shell, the operating circuit that it is characterized in that it is by power rectifier circuit, and the filter circuit of thermistor, capacitor series is formed, and filter circuit also connects rectification circuit output end.
During use, electric heater is connected this device output, at the energising heating initial stage, the resistance of thermistor is very little, and the time constant of filter circuit is bigger, and filtration efficiency reaches maximum, and output end voltage rises to maximum rapidly, and electric heater is rapidly heated.After temperature rose to certain numerical value, the charging and discharging currents of the capacitor that is connected in series with thermistor increased the thermistor resistance, caused filtration efficiency to reduce, and the voltage at heater two ends keeps stable after slowly being reduced to certain value.
