Problems solved by technology

[0005] In addition, the current material distinction between beans and rice can only be distinguished through the input of function keys, and cannot be automatically judged. If the function keys do not correspond to the actual materials, it may cause abnormal performance and the heating power cannot be determined according to the overflow prevention situation. make adjustments

Embodiment 1

[0060] A method of preventing overflow of cooking equipment, such as figure 1 As shown, the method includes S101-S102:

[0061] S101: Detect the rate of change of the voltage value on the anti-overflow electrode; the rate of change of the voltage value refers to the range of change of the voltage value within a certain period of time.

[0062] In the embodiment of the present invention, the installation structure diagram of the anti-overflow electrode is as follows figure 2 As shown, the anti-overflow electrode can be set on the top of the stirring chamber of a cooking device (such as a soymilk machine), the bottom of the stirring chamber is grounded, and there is a dielectric resistance R2 (not shown) between the anti-overflow electrode and the stirring chamber, pull up One end of the resistor R1 is connected to the power supply VCC, and the other end is connected to the overflow prevention electrode, and R1 and R2 form a voltage divider circuit. When the slurry in the stirring c...

Embodiment 2

[0105] The difference between this embodiment and the first embodiment is that a corresponding power adjustment scheme is adopted according to the judgment of the overflow and sticking state in the first embodiment.

[0106] Optionally, the method further includes: calculating the entire anti-overflow duration during the anti-overflow process, and adjusting the heating power according to the anti-overflow duration;

[0107] Among them, the anti-overflow duration includes:

[0108] The length of time to reach the overflow state directly, and,

[0109] The length of time to reach the stuck state and the length of time to reach the overflow state in the stuck state.

[0110] In the embodiment of the present invention, because of different working conditions (such as water level, amount of material, material type, voltage value, etc.), the originally set heating power may not be the best or the most suitable. The anti-overflow duration of the above-mentioned anti-overflow duration th is us...

Embodiment 3

[0119] The difference between this embodiment and the first embodiment is that the material judgment function is realized on the basis of the overflow prevention function realized by the overflow prevention electrode.

[0120] In the embodiment of the present invention, since the current distinction between beans and rice materials can only be distinguished by inputting function keys, it cannot be automatically determined. If the function keys do not correspond to the actual materials, it may cause abnormal performance and heating power. It cannot be adjusted according to the overflow prevention. For this reason, the embodiment of the present invention proposes a solution for judging whether the material is correct based on the voltage value on the anti-overflow electrode.

[0121] Optionally, the method further includes: pre-recording voltage reference values ​​of different materials, and judging whether the current heating material is correct according to the detected voltage val...

Abstract

The embodiment of the invention discloses a spill preventing method for cooking equipment. The method comprises the following steps: detecting the value change rate of voltage on a spill preventing electrode; realizing a spill preventing function in a cooking process according to the value change rate of the voltage. According to the embodiment scheme of the invention, a spill preventing process can be prevented from being affected by materials and water quality, and the spill preventing performance is improved.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of control of cooking equipment, and in particular to a method for preventing overflow of cooking equipment. Background technique [0002] The current soymilk machine includes a machine head upper cover, a machine head lower cover, and an anti-overflow motor installed on the machine head lower cover. There is a detection circuit, and the anti-overflow motor is introduced into the circuit board through a lead wire, through a pull-up resistor and a filter capacitor. And the current limiting resistor is input to the AD detection port of the MCU. If it is detected that the potential of the AD detection port is too low, it means that the slurry is too high and the heating needs to be stopped to avoid the overflow of the soybean milk machine. [0003] As the functions of the soymilk machine are increasing, the functions such as dry soy milk, wet soy milk, five-grain soy milk, rice gruel, rice p...
