Embodiment Construction

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.

[0066] In the related art, the noise of the refrigerator is only tested according to the test method required by the refrigerator noise detection standard before leaving the factory. However, after the refrigerator leaves the factory, how can we know whether the noise generated by the refrigerator during power-on operation can continue to be in a qualif...

Abstract

The invention provides a refrigerator noise detection method and device. The method comprises the steps that if at least one first noise detection module is embedded in a refrigerator, when it is detected that the refrigerator is powered on and runs, the at least one first noise detection module is used for detecting noise data, and then a processing algorithm preset in a noise processing module is used collecting the at least one piece of noise data to obtain a processed noise total decibel value, finally the noise total decibel value is compared with a set noise standard decibel preset, and whether the noise of the refrigerator is qualified or not is determined according to a comparison result. Therefore, according to the scheme, after the refrigerator leaves the factory, whether the noise generated in the power-on operation process of the refrigerator can be continuously in the qualified state or not can still be known.

Description

technical field [0001] The present invention relates to the technical field of refrigerators, in particular to a method and device for detecting noise in refrigerators. Background technique [0002] With the continuous development of technology, refrigerators are becoming more and more intelligent. Since the refrigerator will generate noise during use, if the noise is louder, it will interfere with daily life. Therefore, before the refrigerator leaves the factory, the noise during the operation of the refrigerator will be tested according to the test method required by the refrigerator noise detection standard. If the test result meets the standard requirements, it indicates that the noise generated by the refrigerator is qualified. Only qualified refrigerators can leave the factory and be sold. [0003] The Chinese Patent Application No. 201922261794.8 discloses an online-following refrigerator noise automatic detection system, which is used for refrigerators on the produ...
