Document Type and Number:
WIPO Patent Application WO/2017/124556
Kind Code:
A1
Abstract:
The present invention falls within the field of household appliances, and provides a data acquisition method for technology for detecting a preservation time, and a refrigerator. The method comprises: recording a preservation time limit of food corresponding to a two-dimensional code, and recording the name of the food corresponding to the two-dimensional code; when a user places a freshness protection package labelled with the two-dimensional code into a refrigerator, starting timing; according to the two-dimensional code, determining whether the preservation time limit has expired; if not, staying the same; and if so, displaying the name of the food corresponding to the two-dimensional code, reminding the user that the food corresponding to the two-dimensional code has expired, and sending technique usage data to a data acquisition terminal pre-set by a manufacturer. According to the present invention, by mapping food placed into a refrigerator to a two-dimensional code, and recording a corresponding preservation time limit, the refrigerator automatically reminds a user whether there is expired food, so that the problem of body health being affected by accidental ingestion of expired food is prevented. Moreover, by means of timely feedback after the use of the technology, it is also convenient for a manufacturer to timely and effectively acquire the usage condition of the relevant technique.
