DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a micro-environment fresh-keeping refrigerator, which can digitally and targetedly regulate various fresh-keeping factors such as air composition, air flow pressure, temperature and humidity, oxygen, ozone and negative ion concentrations, and air sterility and purity in the refrigerator in all directions and from multiple angles.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The intelligent positive and negative pressure system is based on positive and negative pressure technology. Positive and negative pressure technology uses positive and negative pressure to precisely control fluids and their payloads to influence objects within a specific space. The technical principle and basic operating method of the intelligent positive and negative pressure system is to intelligently control fluids (such as air and water) using positive and negative pressure, or to carry payloads such as superoxide, catalysts, negative ions, controlled atmosphere gases, and water, to orderly enter, exit, or reside in a specific space (such as a positive and negative pressure chamber) and exert the desired influence on the objects within. The intelligent positive and negative pressure system boasts a large-capacity carrier and a platform with cross-border expansion capabilities, enabling the development of unique targeted influence methods or targeted treatment models for various affected objects. Positive and negative pressure appliances, such as refrigerators and washing machines, designed and manufactured based on the positive and negative pressure system can intelligently and precisely control and create the optimal operating environment and efficiency for the appliances. This represents a significant innovation and upgrade for existing appliances and traditional technologies, opening up a new field of positive and negative pressure appliances. The positive and negative pressure system is applied to the refrigerator, which can intelligently and accurately regulate the refrigerator's air circulation, air flow pressure, gas composition, air sterility and cleanliness, temperature and humidity and other preservation factors in real time, carry out harmless and dead-angle sterilization and disinfection, and quickly degrade harmful residues on the storage surface, realizing all-round and multi-angle digital targeted management for comprehensive preservation of freshness and nutrition. Positive and negative pressure refrigerators use digital technology to integrate preservation technologies such as vacuum, high pressure, ozone, catalysts, controlled atmosphere preservation, negative ions, disinfection, decomposition, humidification, air-to-water production and low-temperature storage. Through the application of the Internet, big data, cloud computing, machine learning, and artificial intelligence digital technologies, an adjustable and controllable artificial microclimate can be formed in the refrigerator, creating a high-energy and efficient preservation microenvironment, so that all fresh food and storage items are in the optimal air pressure range, the most suitable gas composition, the best humidity and temperature, the best storage environment and the best preservation ecology. For the deterioration factors and spoilage elements of different storage items, at the cellular and molecular levels, a digital targeted management comprehensive preservation and nutrition plan is formed to accurately maintain the preservation elements and eliminate the deterioration factors at a fixed point. It can quickly and for as long as possible protect the nutritional content and original freshness of stored items such as fruits, vegetables, meat and fish. It is an original black technology refrigerator and a new generation of refrigerators.
