Since the LOW-E layer has the characteristic of heat insulation, by arranging the LOW-E layer on the glass, the emissivity of the glass can be reduced from 0.84 to below 0.15, so that the glass has the effect of blocking the transmission of thermal radiation. The present application is to coat the LOW-E layer on the glass door plate to enhance the heat insulation effect of the door body; however, the LOW-E layer is easy to oxidize and color under cold and hot conditions, if it is arranged on the side of the inner door plate 13 close to the inner container, although it can block heat transfer, but under repeated high temperature conditions, coloration will occur and finally affect the heat insulation effect, and it is also very easy to scratch the user during the cleaning process of the door body, therefore, the present application arranges the LOW-E layer on the inner side of the outer door plate 11 or the side of the middle door plate 12 close to the inner door plate 13, which not only blocks the heat in the heat insulation cavity, but also facilitates the user to clean the door body. Experimental comparison results show that, compared with the scheme that the inner glass is provided with a LOW-E layer and the middle glass is not provided with a LOW-E layer, the surface temperature of the door body can be reduced by about 5k, the cost is reduced, and the inner surface and the outer surface of the door body become more easy to clean. In addition, the heat blocked in the heat insulation cavity can also be discharged from the first heat insulation hole group at both ends of the air outlet seat 3, effectively reducing the temperature of the door body assembly 1, enhancing the heat insulation effect and preventing scalding of the human body, and the present application can also avoid coloration of the door body assembly 1, improve the heat dissipation effect and safety performance of the door body assembly 1.
