In general, kimchi refrigerator is a kind of refrigerator that maturation is made with preserving pickles that is specifically designed to.Compare with common refrigerator, it can preserve pickles for a long time, and can freely adjust the maturation state.Kimchi refrigerator is to utilize the Pickles jar principle that winter pickles is embedded in underground and maturation and preserves, and it can reduce variations in temperature, and the contacting of blocking-up and air, thereby can keep the fresh taste of pickles for a long time.The storage temperature of kimchi refrigerator generally maintains 0 ℃ to-2 ℃, and this is owing to the acidity variation of pickles under above-mentioned storage temperature is minimum.And the adjustment mode of above-mentioned storage temperature comprises by the circulate direct cooled of cold air of the indirect cooled of cooling fan circulation cold air and the free convection by compartment interior.Above-mentioned direct cooled has the characteristics that chilling rate is slow, power consumption is little and noise is low comparatively speaking, is mainly used in the small electrical refrigerator.On the contrary, above-mentioned indirect cooled has then that chilling rate is fast, power consumption reaches the big characteristics of noise greatly, is mainly used in large-scale refrigerator.Below the process that stores pickles in above-mentioned kimchi refrigerator is described.The refrigerant that kimchi refrigerator uses at first is compressed into high temperature, high pressure conditions in compressor, send into condenser along the refrigerant pipe then.The refrigerant that liquefies through condenser will move to expansion valve along the refrigerant pipe, by becoming low temperature, low-pressure state behind the expansion valve, flow to outside around storeroom subsequently and evaporimeter that be provided with.Above-mentioned refrigerant will absorb heat on every side and produce gasification in evaporimeter, thereby the temperature of body wall is descended.Thus, will its temperature be descended by the free convection or the cooling fan of cold air in the storeroom that forms by body wall, and so just can preserve pickles at low temperatures.Fig. 1 is the kimchi refrigerator structure cutaway view of prior art.As shown in Figure 1, the kimchi refrigerator 1 of this prior art comprises:
