Problems solved by technology

And there are many deficiencies in the soybean milk machine that adopts time control on the market at present.
[0003] Its disadvantages are: 1. The length of preheating time is fixed
2. When pulping at high voltage and low water level, the slurry boils or overflows due to the fixed length of preheating time
3. When pulping at low voltage and high water level, the beating temperature is too low due to the fixed preheating time, which affects the subsequent pulping process and the taste of soybean milk

Embodiment Construction

[0021] First, explain the idea and key of the present invention:

[0022] The grid voltage is detected by the voltage detection unit circuit, and different heating on-times are adjusted by software algorithms according to different grid voltages. Compared with other time-controlled heating circuits, the key of the present invention is the voltage detection unit and the single-chip control process.

[0023] Such as figure 1 As shown, the time-controlled heating circuit of the specific embodiment of the present invention is applied to the preheating of the soybean milk machine, and the voltage detection unit is: the mains electricity passes through the live line L and the neutral line N through the transformer T, and then full bridge rectification and filtering to obtain a relatively smooth DC level, The direct current passes through the variable resistor RX and the voltage divider resistor R to obtain the relative working voltage of the whole machine at the voltage sampling point B. ...

Abstract

The invention relates to a time control heating method and a circuit thereof, wherein the circuit comprises a voltage detection unit, a control unit, a heating unit and a conducting switch; the method comprises the steps of identifying an actual working voltage of the heating unit by the voltage detection unit and reversely adjusting the conducting time of the heating unit according to the actual working voltage. The time control heating method and the circuit thereof do not need a temperature sensor to measure the temperature to heat, can save cost and also can achieve good heating effect.

Description

Technical field [0001] The invention relates to an electronic circuit, in particular to a time-controlled heating method in an applied electronic product and its circuit. Background technique [0002] At present, the pre-heating methods of soymilk machine on the market mainly use temperature sensor to measure the temperature to control the pre-heating process and non-temperature sensor to use time to control the pre-heating. However, there are many shortcomings in the current time-controlled soymilk machine on the market. [0003] Its shortcomings are: 1. The length of preheating time is fixed. 2. When making slurry at high voltage and low water level, the slurry will boil or overflow due to the fixed length of preheating time. 3. When pulping at low voltage and high water level, the beating temperature is too low due to the fixed length of preheating time, which affects the subsequent pulping process and the taste of soybean milk. Summary of the invention [0004] The technical ...
