Super-hydrophobic door sealing strip for refrigerator and preparation method of super-hydrophobic door sealing strip

Abstract

The invention discloses a super-hydrophobic door sealing strip for a refrigerator and a preparation method of the super-hydrophobic door sealing strip, and relates to the technical field of householdappliances. The super-hydrophobic door sealing strip comprises a refrigerator door sealing strip body and a refrigerator door inner container. Clamping grooves are formed in the refrigerator door sealing strip body. Omega-shaped grooves are clamped and connected in the clamping grooves. Grooves are formed in the omega-shaped grooves. A super-hydrophobic nano material layer is sprayed to the innersurface of each groove. The super-hydrophobic nano material layer is a nano titanium dioxide fluorine-containing polymer. Super-hydrophobic treatment is carried out on the portion, prone to condensation, of the door sealing strip body, in other words, the special portion of the door sealing strip body is coated with the super-hydrophobic material coating, moisture on the coating cannot be condensed, and condensation at the door seal position of the refrigerator can be continuously and effectively eliminated for a long time.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a superhydrophobic door seal used for refrigerators and a preparation method thereof. Background technique [0002] The refrigerator insulation system is mainly realized by the insulation layer and sealing effect of the refrigerator. With the prevalence of air-cooled refrigerators, the enhancement of internal air circulation has an impact on the insulation effect of the refrigerator's inner box and door seal. Due to the leakage of cold air at the joint between the door and the box, the temperature difference between the inside and outside is large, resulting in condensation on the door seal. dew.

AI Technical Summary

Problems solved by technology

[0003] In order to prevent condensation, on the one hand, an anti-condensation pipe can be installed at the junction of the freezer inner liner and the outer shell of the refrigerator for the freezer door body. However, this heating method is limited by the working time of the refrigeration system on the one hand. When the refrigerator is shut down, Without the heat supply of the refrigeration system, the temperature of the door body and the door seal and the beam drops rapidly, and the outside humid air condenses here quickly at this time, and the refrigeration system cannot have enough heat to evaporate it when the refrigeration system runs again, and accumulates at the door seal for a long time Condensation; on the other hand, due to the influence of the refrigerator manufacturing process, the pipes and the inner shell are not tightly bonded, and the heat of the refrigeration system is difficult to transmit

It is possible to eliminate condensation by pasting materials with thermal conductivity such as aluminum foil on the decorative strips, but due to its limited heat transfer, it can only eliminate slight condensation, and cannot completely solve the problem of condensation on door seals

There are also some heating devices pasted on the inner surface of the door trim, but it is easy to cause local overheating and cause deformation of the non-metallic door trim, which affects the appearance of the refrigerator

[0004] To sum up, in terms of anti-condensation on refrigerator door seals, whether it is only adding a heating device, or controlling the heating of the heating device through a control method, there is no doubt that energy consumption will add a burden to the refrigerator.
