Problems solved by technology

[0003] However, after storing a large amount of food in the refrigerator, the following problems often occur: users may forget that certain foods are stored in the refrigerator, causing the food to expire and produce a pungent odor; Stale due to long storage time
Although refrigerators can keep fresh at low temperature, there is no way to completely inhibit the growth of bacteria, and current refrigerators generally cannot eliminate bacteria, and can only use low temperature to slow down the growth of bacteria
Food becomes stale or even expired due to long-term storage, which not only affects the user's experience, but more importantly, may have an impact on the user's health after eating
