Embodiment approach 1

[0016] Embodiment 1: According to the analog value signal associated with the magnitude of the mains input voltage, the data processing unit generates a full-wave drive signal associated with the mains voltage, and the power switching device of the power control unit performs full-wave on-off control, so as to realize heating The effective power control of the heating unit of the blanket; the power loading mode of the heating unit is as figure 2 Shown.

Embodiment approach 2

[0017] Embodiment 2: According to the analog value signal associated with the above-mentioned mains input voltage, the data processing unit generates a half-wave drive signal associated with the mains voltage, and the power switching device of the power control unit performs half-wave on-off control, so as to realize heating The effective power control of the heating unit of the blanket; the power loading mode of the heating unit is as image 3 Shown.

Embodiment approach 3

[0018] Embodiment 3: According to the analog value signal associated with the above-mentioned mains input voltage, the data processing unit generates a conduction angle drive signal associated with the mains voltage, and the power switching device of the power control unit performs sinusoidal waveguide pass angle control, which also achieves The effective power control of the heating unit of the electric blanket; the power loading mode of the heating unit is as Figure 4 Shown.

[0019] It needs to be understood that: because the present invention uses the mains voltage divided analog value signal as the basis for power control of the heating device, through the logic or data processing unit, the corresponding drive control signal is provided in a predetermined mode, and through a power control switch device, Load the appropriate power to make the electric blanket heating unit work in the rated effective power range; moreover, the above-mentioned control method and process are no...

Abstract

The invention relates to a control method for adapting a wide input voltage electric heating product controller, for solving the problem that the electric heating product can realize normal use without difference under the condition of different standards of an international civil power grid; the corresponding control method is implemented according to the level of the input voltage so that the electric heating product works under different mains voltage situations and maintains to work at a rated power; that is, the mains supply is subjected to voltage sampling, data processing and power control so that the product is maintained to work in a rated effective power range under the situation of the input voltage being a range of 90-260Vac. Specifically, the invention relates to a control method of the electric heating product controller; the electric power loading proportion is automatically adjusted according to the level of the input mains voltage through mains voltage sampling and MCUanalytic processing; the power loading quantity of the heating unit is controlled so that the electric heating product is maintained to work at the rated effective power with the input voltage in a range of 90-260Vac.

Description

Technical field [0001] The invention relates to the manufacturing field of electronic and electrical products related to electronics. Specifically, it relates to a control method for a control circuit of a household electric blanket, which belongs to the field of household electronic and electrical products and control circuit manufacturing. Background technique [0002] An electric blanket is a human-contact electric heating appliance. It implants a specially made cord-type electric heating element with insulation performance up to safety standards into the interior of the textile fabric, and emits heat when it is energized. It uses electric heating elements to generate heat to achieve the purpose of heating and dehumidification. Compared with other electric heating methods, it has the characteristics of low energy consumption, good effect, temperature control, and wide use. Its development has a history of 100 years. Its types include electric mattresses, blankets, shawls, an...
