Description

Anti-condensation device for side-by-side combination refrigerator

Technical Field

The invention relates to the technical field of refrigerators, in particular to an anti-condensation device for a side-by-side combination refrigerator.

Background

Condensation is the phenomenon that when high-temperature and high-humidity gas meets a low-temperature object, the gas is liquefied into liquid on the surface when reaching the dew point temperature. Because the temperature in the refrigerator body is far lower than the temperature outside the refrigerator, and the cold quantity in the refrigerator body is diffused to the outside of the refrigerator body through the heat insulation layer and the door seal strip, the surface temperature of the surface of the refrigerator body and the surface temperature of the door body are lower, and the cold quantity can be condensed into dew when meeting high-temperature and high-humidity gas, so that the condensation phenomenon is generated. The condensation phenomenon not only affects the appearance of the refrigerator, but also adsorbs dust and impurities in the air. Long-time condensation can cause corrosion and rust of metal parts and odor and mildew of plastic parts, and reduce the service life of the refrigerator.

The existing anti-condensation measures for the side-by-side combination refrigerator are that anti-condensation pipes are arranged around a freezing container, and when the refrigerator refrigerates, heat emitted by the anti-condensation pipes is utilized to evaporate and condense condensed water around a door seal of the freezing chamber, so that the anti-condensation effect is achieved.

Chinese patent discloses a prevent condensation device (grant publication No. CN108955043B) for side-by-side combination refrigerator, this patent technique is through being provided with the refrigerator body, two refrigerator doors and two handles, one side of two refrigerator doors articulates on the refrigerator body, the opposite side of two refrigerator doors is contradicted each other, two handle fixed connection are on the lateral wall of corresponding refrigerator door, the steam in preventing the condensation pipe comes out from the louvre, through the air vent on the connecting plate, then steam will blow to the sponge piece, make the temperature on the sponge piece be unlikely to and produce the condensation with external difference too big. Hot gas flows out of the first vent pipe and flows out of the airflow hole through the second vent pipe, so that condensation at the joint of the two sealing strips is also ensured; first breather pipe transmits the heat of self for the sleeve, and the rethread is through the heat conduction stick heat conduction to with higher speed thermal transmission, transmit the block rubber from the stripper bar at last, the block rubber distributes away the heat, thereby changes the difference in temperature, prevents the production of condensation, but, when opening the refrigerator door, be difficult to quick open the drawer in the refrigerator, and be not convenient for with heat fast transfer to preventing in the condensation pipe, be difficult to the drive power supply of quick start heating piece moreover.
