Problems solved by technology

[0002] At present, the control method of the fan of the refrigerator on the market is that when the refrigerator is opened, the door fan stops immediately, but the fan speed is generally above 2000RPM (Round Per Minute, revolutions per minute), so the sudden stop of the fan will produce impact noise , resulting in a very bad user experience for the refrigerator
In addition, the refrigerator in the related art controls the speed of the fan according to the real-time temperature of the refrigerator, but cannot intelligently adjust the speed of the fan according to the real-time usage of the refrigerator by the user.
Therefore, when the user is close to the refrigerator or using the refrigerator, the user can hear the noise generated by the fan, thereby degrading the user's experience of the refrigerator

Abstract

The invention provides a fan rotating speed control method and device and a refrigerator. The fan rotating speed control method includes the steps that the distance between a user and the refrigerator is obtained; the rotating speed of a fan is controlled according to the distance. According to the technical scheme, when the user is close to or uses the refrigerator, the rotating speed of the fan of the refrigerator decreases in a stepwise mode; when the distance between the user and the refrigerator exceeds a certain range, the rotating speed of the fan increases in a stepwise mode; on the one hand, the noise generated when the fan works can be lowered, on the other hand, the noise generated when the rotating speed of the fan changes suddenly can be eliminated, and thus the user experience of the refrigerator is improved.

Description

technical field [0001] The present invention relates to the technical field of refrigerators, in particular to a fan speed control method, a fan speed control device and a refrigerator. Background technique [0002] At present, the control method of the fan of the refrigerator on the market is that when the refrigerator is opened, the door fan stops immediately, but the fan speed is generally above 2000RPM (Round Per Minute, revolutions per minute), so the sudden stop of the fan will produce impact noise , resulting in a very bad user experience for the refrigerator. In addition, the refrigerator in the related art controls the speed of the fan according to the real-time temperature of the refrigerator, but cannot intelligently adjust the speed of the fan according to the real-time use of the refrigerator by the user. Therefore, when the user approaches the refrigerator or uses the refrigerator, the user can hear the noise generated by the fan, thereby degrading the user's ...
