[0052] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] The intelligent positive and negative pressure system is established based on positive and negative pressure technology. Positive and negative pressure technology is to use positive and negative pressure to regulate fluids and their carriers to accurately affect objects in a specific space; the technical principle and basic operation method of the intelligent positive and negative pressure system is: to use positive and negative pressure to intelligently regulate fluids (such as air and water), or to carry payloads such as superoxide, catalysts, negative ions, gas conditioning gases, water, etc., to orderly enter and exit or stay in a specific space (such as a positive and negative pressure warehouse) and exert the desired influence on the objects therein; the intelligent positive and negative pressure system has the advantages of ultra-large-capacity carrier performance and cross-border expansion platform, and can form targeted influence methods or targeted governance modes with their own characteristics for various affected objects. Various positive and negative pressure electrical appliances such as positive and negative pressure refrigerators and positive and negative pressure washing machines designed and manufactured based on the positive and negative pressure system can intelligently and accurately regulate and create the optimal environment and optimal efficiency for the operation of electrical appliances, which innovates and replaces existing electrical appliances and traditional technologies, and develops a new field of positive and negative pressure electrical 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, perform 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 stored 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 stored 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.
