Embodiment 1

[0056] An embodiment of the present invention provides a motor protection method for a food processing machine. The food processing machine may include a temperature sensor and a motor, such as figure 1 As shown, the method may include S101-S103:

[0057] S101. Detect the temperature of the motor body through a temperature sensor;

[0058] S102. Comparing the detected temperature of the motor body with at least two preset standard temperature values;

[0059] S103. Adjust the working process of the motor according to the comparison result, so as to protect the motor from temperature rise.

[0060] In the embodiment of the present invention, the food processing machine can be composed of an operation interface, a control circuit board, a heating module, a crushing chamber, and a motor, wherein the control circuit board can be provided with a main control circuit or a main control chip; A temperature sensor is provided, and the temperature sensor can provide the detected tempe...

Embodiment 2

[0065] This embodiment provides several specific examples of standard temperature values ​​on the basis of the first embodiment.

[0066] Optionally, the preset standard temperature values ​​may include: a first standard temperature value T1, a second standard temperature value T2 and a third standard temperature value T3;

[0067] Wherein, the first standard temperature value T1 is less than the second standard temperature value T2, the second standard temperature value T2 is less than the third standard temperature value T3, and the third standard temperature value T3 is less than or equal to the insulation failure temperature value of the motor body.

[0068] In the embodiment of the present invention, the solution of this embodiment realizes three-level temperature protection for the motor, so as to limit the temperature of the motor body from exceeding the standard and ensure that the motor is not damaged.

[0069] In the embodiment of the present invention, the third sta...

Embodiment 3

[0071] On the basis of the second embodiment, this embodiment provides a specific implementation manner of adjusting the working process of the motor according to the comparison result.

[0072] Optionally, adjusting the working process of the motor according to the comparison result may include the following situations 1-4:

[0073] 1. When the detected temperature of the motor body is less than or equal to the first standard temperature value T1, control the motor to run according to the preset working process.

[0074] In the embodiment of the present invention, during the operation of the motor, when it is detected that the temperature of the motor body is lower than the first standard temperature value T1, it means that the current temperature of the motor body is kept within an absolutely safe temperature range, so the original set speed can be used. run.

[0075] 2. When the detected temperature of the motor body is greater than the first standard temperature value T1 ...

Abstract

The embodiment of the invention discloses a motor protecting method of a food processing machine. A temperature sensor and a motor can be included in the food processing machine. The method comprisesthe steps that the temperature of a motor body is detected through the temperature sensor; detected temperature of the motor body is compared with at least two preset standard temperature values; theoperating process of the motor is adjusted according to comparison results to perform protection of the motor. By means of the method, real-time monitoring and protecting are conducted on the motor without the constraint of various specific conditions, and a product is more reliable.

Description

technical field [0001] The embodiment of the present invention relates to cooking equipment control technology, especially to a motor protection method of a food processing machine. Background technique [0002] The pulping function of a food processor (such as a soybean milk machine) is inseparable from heating and crushing. Heating makes the added materials ripen, releases nutrients and sterilizes them at high temperature, and crushing makes the added materials divided into smaller sizes for nutrient release. At the same time, it is more suitable for drinking. [0003] Usually, the heating of the food processor is realized by a heating device (such as a heating tube / disk / cavity), and the crushing is realized by a motor driving a blade to rotate at a high speed to shear the material. In special cases, the motor will generate a lot of heat due to its efficiency during operation, and because the closed working environment where the motor is located cannot dissipate heat, the...
