Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a cabinet body, door bodies, heating modules and sterilization modules, wherein storage spaces are limited in the cabinet body; storage containers are respectively arranged in the storage spaces; variable-temperature spaces are respectively limited in the storage containers; each door body is arranged on the front surface of the cabinet body to close the corresponding storage space; each heating module is arranged on the corresponding storage container and is configured to provide heat for the corresponding variable-temperature space in a controlled manner; each sterilization module is arranged on one side of the corresponding heating module, and space around each sterilization module communicates with the corresponding variable-temperature space; and each sterilization module comprises tourmaline, so that negative ions are released through the corresponding tourmaline under the situation that the corresponding heating module is started to perform sterilization and preservation on the corresponding variable-temperature space. According to the refrigerator disclosed by the invention, the negative ions are released through the tourmaline under the situation that the corresponding heating module is started, the growth of bacteria is inhibited, the activity of enzymes during the metabolism of fruits and vegetables is inhibited, and the yield quantity of ethylene with the function of accelerating maturation is reduced, so that sterilization and preservation for food materials in the corresponding variable-temperature space are realized, and the storage effect of the food materials is improved.

Description

technical field [0001] The invention relates to the field of item storage, in particular to a refrigerator. Background technique [0002] With the development of society and the improvement of people's living standards, and people's pace of life is getting faster and faster, people often buy a lot of items and place them in various refrigerators, but for leafy vegetables and fruits and vegetables, the storage of refrigerators The low temperature in the space will not only cause wrinkles and spots on the skin of these foods, affecting their original taste and nutrition, but also cause bacteria to grow in the food itself after long-term storage, causing the food to gradually spoil and lead to waste. [0003] In the prior art, the storage life of food materials is generally extended by modified atmosphere preservation technology. Modified atmosphere preservation technology generally refers to the technology of prolonging the storage life of food materials by adjusting the gas ...

Problems solved by technology

[0005] However, the traditional nitrogen-generating equipment used for controlled atmosphere fresh-keeping is bulky and costly, so that this technology is basically limited to use in various large-scale professional storage warehouses (the storage capacity is generally at least 30 tons or more).

It can be said that what kind of appropriate gas adjustment technology and corresponding devices can be used to economically miniaturize and q
