Simple air duct device with anti-condensation, anti- vibration and fireproof functions

Abstract

The invention discloses a simple air duct device with anti-condensation, anti-vibration and fireproof functions. The simple air duct device is characterized in that air duct foam is installed on a front air duct mask, and a fireproof plate and aluminum foil sponge are sequentially installed at the lower end of the rear end face of the air duct foam; a return air inlet is formed in the lower end ofa front fan cover panel, a plurality of air outlets are formed in one surface of the front fan cover panel, air outlet holes communicate with a centrifugal fan mounting groove through an air duct, and a centrifugal fan is fixed in the centrifugal fan mounting groove; and a rear air duct cover plate is installed at the upper end of the rear end face of the air duct foam. According to the simple air duct device, the centrifugal fan is installed through the air duct foam, and the damping effect is improved; the air duct foam is provided with the air duct and the air outlets to supply cold air toall chambers, and air guide bosses are arranged to facilitate conveying of the cold air to the multiple air outlets and air guide of the air duct; and the fireproof plate is installed through a fireproof plate installation groove, collapse of the aluminum foil sponge is prevented, a stable air duct channel is conveniently formed in a sealed mode, and when aluminum foil in the aluminum foil spongeloses efficacy, the effect of fire prevention of second air duct foam is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a simple air duct device with anti-condensation, shock resistance and fire prevention. Background technique [0002] In the existing refrigerator air duct device, basically all are a front air duct panel, a rear air duct panel and a fan.
