Detecting method and device of fan operation state, electric appliance and storage medium

Abstract

The invention discloses a detecting method and device of the fan operation state, an electric appliance and a storage medium. The detecting method of the fan operation state includes the steps that response to a fan electric current reference value calibration instruction is made, and at least one operation gear position of a fan is obtained according to the fan electric current reference value calibration instruction; the fan is controlled to operate in each operation gear position, and the corresponding fan electric current average value when the fan operates in each operation gear positionis detected and obtained; each fan electric current average value is set to be the fan electric current reference value of the corresponding operation gear position; and response to a fan operation instruction is made, the fan is controlled to operate according to the fan operation instruction, and the operation state of the fan is detected through all the fan electric current reference values. Bymeans of the detecting method and device of the fan operation state, the electric appliance and the storage medium, the accuracy of a detection result obtained after detection of the fan operation state can be improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for detecting the running state of a fan, an electrical appliance, and a storage medium. Background technique [0002] With the improvement of living standards, almost every household now has its own range hood. In some houses, public flues are still used for smoke exhaust. When there are multiple range hoods exhausting smoke at the same time in a building, it is very likely that the damper of the range hood will be closed due to the excessive air pressure in the public flue, which not only leads to the failure to discharge the indoor lampblack normally, but also causes Huge security risk. [0003] In the prior art, in order to solve the above problems, a reference value of fan current is usually set in the range hood, and the current value of the fan is detected in real time, and the difference between the current value of the fan and the aforementioned r...

Problems solved by technology

When there are multiple range hoods exhausting smoke at the same time in a building, it is very likely that the damper of the range hood will be closed due to the excessive air pressure in the public flue, which not only leads to the failure to discharge the indoor lampblack normally, but also causes huge security risk

[0003] In the prior art, in order to solve the above problems, a reference value of fan current is usually set in the range hood, and the current value of the fan is detected in real time, and the difference between the current value of the fan and the aforementioned reference value is monitored. Whether it exceeds a certain range, if yes, it is determined that the air outlet of the range hood is blocked, so turn off the range hood or prompt the user to take corresponding measures, if not, it is determined that the air outlet of the range hood is unblocked, and the range hood is operating normally, so no processing is performed

[0004] In the prior art, the reference value of the above-mentioned fan current is usually set by technicians based on their own experience, and the accuracy is difficult to guarantee. Therefore, when detecting the operating status of the range hood, it is very likely that the detection result will be wrong. Phenomenon
