Example Embodiment

[0020] Such as figure 1 As shown, in this embodiment, the composition of a refrigerator food freshness reminder system includes: a sensor module, a control module, a display module, an alarm module, and a button module;

[0021] The sensor module is used to obtain the total volatile basic nitrogen content value of the food in the refrigerator freezer compartment and / or refrigerator freezer, and send it to the control module;

[0022] The button module sets different levels of total volatile basic nitrogen critical values ​​for different total volatile basic nitrogen content of food; figure 2 As shown, food can be classified according to freshness during storage. In this embodiment, the key module sets three thresholds of total volatile base nitrogen N1, N2, and N3 respectively, and the three thresholds of total volatile base nitrogen form four fresh areas, respectively, First-level fresh [0, N1], second-level fresh (N1, N2], suspicious food (N2, N3) and spoilage (N3, +∞); the tota...

Abstract

The invention discloses a refrigerator food freshness segmentation reminding system and an application thereof. The refrigerator food freshness segmentation reminding system is characterized by comprising a sensor module, a control module, a display module, an alarm module and a press key module, wherein the sensor module is used to obtain total volatile base nitrogen content values of food in a refrigerating chamber of a refrigerator and/ or a freezing chamber of the refrigerator, and send the total volatile base nitrogen content values to the control module, the press key module respectively sets different levels of total volatile base nitrogen criticality values according to the different total volatile base nitrogen content values of the food, and the control module receives the total volatile base nitrogen content values, compares the total volatile base nitrogen content values with the different levels of the total volatile base nitrogen criticality values, judges signals of the levels where the total volatile base nitrogen content values are located, and sends the signals to the display module to perform character or icon caution and to the alarm module to perform voice caution and/ or lamplight alarm caution and/ or short message caution for the refrigerator. The refrigerator food freshness segmentation reminding system can effectively monitor fresh status of all kinds of the food in the refrigerator in real time, and guarantees edible safety of the food.

Description

technical field [0001] The invention relates to the field of smart refrigerators, in particular to a refrigerator food freshness segment reminder system and its application. Background technique [0002] With the acceleration of people's life rhythm, the lifestyle of centralized purchase of food on weekends is becoming more and more common, which can effectively reduce the time spent on food purchases every week, save time and effort, but it also brings about the safety of some refrigerator food storage question. Users buy a lot of food each time, causing some of them to be forgotten to eat. After a week or more of food accumulation, especially in the freezer of the refrigerator, it is difficult to distinguish the purchase time and freshness of the food, resulting in hidden safety hazards. Contents of the invention [0003] In view of the above problems, the present invention provides a refrigerator food freshness segmentation reminder function system and its application,...
