Positive-negative pressure system, operation method thereof and positive-negative pressure electric appliance using system

Abstract

The invention relates to a positive-negative pressure system, an operation method thereof and a positive-negative pressure electric appliance using the system. The positive-negative pressure electricappliance comprises: a positive-negative pressure refrigerator, a positive-negative pressure washing machine, a vacuum dish washing and fruit-vegetable cleaning machine, a super-oxygen washing range hood, a positive-negative pressure oven fryer microwave oven, a positive-negative pressure fresh-keeping compartment, a positive-negative pressure fresh-keeping warehouse and a positive-negative pressure module cabinet. According to the technical principle and the basic operation method of the positive-negative pressure system, air flow is regulated and controlled through positive and negative pressure, or multiple effective loads like ozone, air catalysts, negative ions, air-conditioned gas and water are carried for orderly getting in and out of the positive-negative pressure cabins or staying, and needed influences are exerted on objects therein. Accordingly, multiple technologies like vacuum, high pressure, ozone, catalysts, controlled atmosphere fresh-keeping, negative ions, disinfection and purification, humidification and dehumidification, air water production and low-temperature storage are regulated and integrated through the positive-negative pressure system and are combined and applied to the positive-negative pressure electric appliance, a breathing function is given to the electric appliance, and a positive-negative pressure electric appliance subdivision field is developed for upgrading and updating existing electric appliances and traditional technologies.

[0002] The field of production and living electrical appliances has developed rapidly in recent decades, especially the increasing popularity of refrigerators and washing machines. However, in recent years, the upgrading of home appliances has not been satisfactory. In recent years, although the appearance of the refrigerator has been improved to be very beautiful and various auxiliary functions have been added, there has been no technological breakthrough in the basic storage method of low-temperature antibacterial

The characteristics of vacuum and high pressure have long been known. Bacteria and microorganisms cannot survive in a vacuum. Preservation of fruits, vegetables, meat and fish is not perishable. It has always attracted people to use vacuum to store food. However, there is no oxygen in the vacuum, which will lead to anaerobic respiration of fruits and vegetables, which will damage the quality and freshness. At the same time, when the vacuum negative pressure is too low, it will destroy the cells and tissue structure of fruits, vegetables, meat and fish, resulting in spoilage, which will speed up the escape and loss of internal moisture in fruits, vegetables, meat and fish, resulting in a decrease in quality and loss of flavor. Due to the mixed advantages and disadvantages, it has not been practically used in refrigerators. and other home appliances; high-pressure technology is used in the field of refrigeration and refrigeration. After years of research, it has been proved that: the use of high-pressure antibacterial, high-pressure freezing, high-pressure thawing and high-pressure non-freezing refrigeration technology can solve the problem of atmospheric pressure freezing and thawing through the coordinated configuration of pressure and temperature. and the technical problem of irreversible quality damage to food caused by the maximum ice crystal formation zone in frozen preservation, and the speed of high-pressure freezing and thawing is much faster than that under normal pressure. However, creating a deep vacuum and ultra-high pressure space in household appliances, Existing materials and technical levels are very difficult to realize. There are many problems, and the cost is too high to be suitable for household appliances. Due to the above reasons, vacuum and high-voltage technology have not been practically applied to refrigerators and other production and living appliances.

Superoxide (ozone) can quickly sterilize and degrade pesticide residues and organic dirt, inhibit enzyme activity, keep fresh fruits, vegetables, meat and fish, and many other advantages have been attracting people to apply it to production and daily needs. Oxygen will endanger human health, and there has been no ideal solution for applying it to electrical appliances. As a result, superoxide has not been practically applied to household appliances such as refrigerators and washing machines. Oxygen, nitrogen, carbon dioxide concentration ratio in the space, etc., inhibit the respiration of fruits and vegetables, reduce the consumption of organic matter, maintain the original good flavor and aroma, delay metabolism, control the breeding of certain pathogenic bacteria and the occurrence of physiological diseases, The fresh-keeping effect is much better than that of ordinary refrigeration, the fresh-keeping period is significantly prolonged, and the power consumption is small. However, controlled atmosphere storage requires an airtight space that can withstand a certain pressure. Input, and at the same time, the waste gas must be discharged in a timely manner, and the exhalation of the modified atmosphere gas requires the precise maintenance of the circulation system, etc., all of which are beyond the reach of ordinary refrigerators; in fact, the refrigerators of the prior art also have a The fatal defect affecting freshness preservation has not been solved or has not been discovered or taken seriously. That is, there is no ventilation function. The air in the box will soon become dirty and affect the freshness preservation effect. Although the opening and closing of the box door has a certain ventilation effect, it is not thorough and unreliable. Above all shortcoming, all obtain basic solution in the embodiment of the present invention
