Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] see figure 1 , a food shelf life reminding device for a refrigerator, comprising a processor arranged on the refrigerator, an input device, a display, and an alarm, wherein the input device, the display, and the alarm are all connected to the processor;

[0025] The processor adopts LPC2103 microprocessor, which is used to obtain the shelf life of food, food production date, and food name information from the input device, and compares it with the current clock of the system to determine the time to remind the shelf life;

[0026] The input device is composed of a barcode scanner and a handwriting touch screen, and is used for inputting food information, including food name, production date and shelf life.

[0027] The display is a handwriting touch screen, which displays food information and is used to browse food storage information and shelf life information in t...

Abstract

A reminding device for the shelf life of the food in a refrigerator comprises a processor, an input device, a displayer and an alerter, wherein the processor, the input device, the displayer and the alerter are arranged on the refrigerator, and the input device, the displayer and the alerter are all connected with the processor. A reminding method of the reminding device comprises the steps that (1) food information is input through a barcode scanner or a handwriting touch screen; (2) the processor sets shelf life reminding time in sequence according to the food information obtained from the input device and the set information of a user; (3) when the set shelf life reminding time arrives, the system will give out voice prompts at fixed moments every day or at the moment when the user opens the door of the refrigerator, and visual prompting signals are given out constantly at the rest of moments through the flicker of an LED lamp to enhance prompting effects. The reminding device and the reminding method thereof for the shelf life of the food in the refrigerator can effectively lower the harm caused by the expiration of the food, and have the advantages of being simple in structure, intelligent and strong in practicality.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and specifically refers to a food shelf life reminding device and a reminding method for refrigerators. Background technique [0002] Along with the day by day development of social economy, people's living standard improves constantly, and many families have purchased refrigerator to be used for preserving food. However, as the amount of food in the refrigerator continues to increase, users sometimes forget the specific shelf life of some quick-frozen foods or foods with a short shelf life, which makes some food go bad, and then breeds bacteria, pollutes the internal environment of the refrigerator, and endangers food safety and the user's health. healthy. Also caused some unnecessary waste simultaneously. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a food shelf life remindi...
