Intelligent refrigerator and intelligent refrigerator food storage management method based on Internet of Things technology

Abstract

The invention discloses an intelligent refrigerator and an intelligent refrigerator food storage management method based on an Internet of Things technology. The intelligent refrigerator is connected with a wide area network, and comprises a working area and at least one storage area which are arranged separately, wherein the storage areas comprise storage chambers and refrigerator doors which are arranged correspondingly; microswitches are mounted at contact parts between the storage chambers and the refrigerator doors; main control boards, refrigeration compressors and gateways are mounted in the storage areas; food type information acquisition modules are arranged on top boards of the storage chambers; a plurality of storage cases are placed in the storage chambers; weight acquisition devices are arranged at the bottoms of the storage cases; and temperature sensors are arranged in the storage chambers. The intelligent refrigerator can acquire type information, appearance information, weight information and storage time information of food in the refrigerator in real time, and transmit the information of the food to the wide area network in a wired or wireless mode, and a user accesses the wide area network through external equipment, knows the information of the food in the refrigerator very well at any time, and accurately manages the food according to the information.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to an intelligent refrigerator based on Internet of Things technology and a method for managing stored food thereof. Background technique [0002] With the rapid development of society, the residences of urban residents continue to extend to areas outside the city center, making refrigerators play an increasingly important role in residents' lives. At present, the functions of refrigerators are constantly increasing, and the volume of refrigerators is also increasing, so as to meet the needs of users for storing more food in the refrigerators. Due to the faster and faster pace of people's work and life, users often forget the type, quantity and storage time of food in the refrigerator. This will cause problems in the following aspects: [0003] 1. Users need to switch on and off the refrigerator frequently to check the types of food in the refrigerator and ...

AI Technical Summary

Problems solved by technology

[0003] 1. Users need to switch on and off the refrigerator frequently to check the types of food in the refrigerator and the quantity of various foods, which will increase the energy consumption of the refrigerator and reduce the service life;

[0004] 2. It is difficult for users to accurately remember the storage time of different types of food in the refrigerator. They often find that the food has passed the best use period or has deteriorated and cannot be eaten when the food is taken out of the refrigerator. This not only causes food waste, but also has deteriorated. The food will also pollute the undeteriorated food in the refrigerator, causing other food to spoil;

[0005] 3. Domestic residents generally pay attention to the combination of different ingredients (meat, vegetables, etc.) in the cooking process. When residents purchase ingredients outdoors, they cannot accurately grasp the types and quantities of vegetables and meat in the refrigerator, and it is difficult to target the existing ingredients in the refrigerator. Purchasing other ingredients purposefully to match the ingredients already in the refrigerator can also easily lead to repeated purchases or excessive purchases

The above method solves the problem of food information acquisition, and helps to scientifically manage the food in the refrigerator, but the above method only displays the obtained food information on the control panel of the refrigerator, and it is difficult for users to obtain this information anytime and anywhere. The food in the refrigerator cannot be effectively managed
