Problems solved by technology

[0004] (1) The material gradually decreases with the blowing time, but the power required to blow the material is decreasing, the operating pressure of the fan is reduced and the wind speed is increased, which may cause waste of power consumption
[0005] (2) When the power pipeline is blocked by abnormal materials, the operating pressure of the fan increases abnormally, which may cause the fan to burn out
[0006] (3) When the operating pressure of the fan decreases and the wind speed increases, due to the high wind speed, it will generate a lot of noise, which seriously affects the user experience

Embodiment 1

[0056] figure 1 A schematic flowchart of an operation control method of a fan according to an embodiment of the present invention is shown.

[0057] Such as figure 1 As shown, the operation control method of the fan according to an embodiment of the present invention includes: step S102, when executing the process of blowing materials, determine the load current of the fan according to the preset cycle; step S104, according to the load current and the preset current threshold The relationship between the size of the fan to adjust the duty cycle used to determine the speed of the fan.

[0058] In this technical solution, based on a large number of experimental results, it is determined that there is a negative correlation between the amount of remaining material and the load current. Therefore, by determining the load current of the fan according to the preset cycle when performing the material blowing process, according to the load current and the preset The size relations...

Embodiment 2

[0071] figure 2 A schematic block diagram of an operation control device for a fan according to an embodiment of the present invention is shown.

[0072] Such as figure 2 As shown, the fan operation control device 200 according to an embodiment of the present invention includes: a determination unit 202 for determining the load current of the fan according to a preset cycle when performing the process of blowing materials; an adjustment unit 204 for determining according to The magnitude relationship between the load current and the preset current threshold adjusts the duty ratio used to determine the rotational speed of the fan.

[0073] In this technical solution, based on a large number of experimental results, it is determined that there is a negative correlation between the amount of remaining material and the load current. Therefore, by determining the load current of the fan according to the preset cycle when performing the material blowing process, according to the ...

Embodiment 3

[0086] image 3 A schematic block diagram of a fan according to an embodiment of the invention is shown.

[0087] Such as image 3 As shown, the fan according to an embodiment of the present invention includes: the operation control device of the fan as defined in any one of the above technical solutions, the operation control device of the fan can be divided into two parts: the fan drive and the fan load, and the current sampling current Connected to the controller, the controller obtains the load current If detected according to the preset cycle, and the controller adjusts the PWM signal output by the fan drive current. Correspondingly, the power of the fan M is adjusted by the controller PWM (Pulse-Width Modulation, pulse width modulation ) duty cycle, that is, the load current If can be adjusted by adjusting the PWM duty cycle.

[0088] Among them, the size of the load current is related to the structure of the Misuo, the structure of the air duct, and the amount of rice...

Abstract

The invention provides an operation control method and device of a fan, the fan, a cooking utensil and a storage medium. The operation control method of the fan comprises the following steps of when amaterial blowing process is executed, determining a load current of the fan according to a preset period; and according to a relationship between the load current and a preset current threshold, adjusting a duty ratio which determines the magnitude of a drive current of the fan. According to the technical scheme, the failure rate of the fan can be reduced, the noise generated in the operation process of the fan is reduced, and the usage experience of a user is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of fans, in particular to a fan operation control method, a fan operation control device, a fan, a cooking utensil and a computer-readable storage medium. Background technique [0002] With the development of automation technology, more and more cooking utensils have been developed with automatic cooking functions, that is, after the user sets the cooking function, the cooking utensils automatically perform the feeding, feeding, washing and cooking processes. [0003] In the related art, a feeding pipeline is usually set between the storage part and the cooking part of the cooking utensil to realize the feeding and feeding process, and a fixed wind speed is used to blow the material to the cooking part. However, this blowing method has at least the following technical problem: [0004] (1) The material gradually decreases with the blowing time, but the power required to blow the material is decreasi...
