Detailed Description

The utility model will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the labyrinth-seal refrigerator drainage device comprises a drainage bottom plate, wherein the drainage bottom plate comprises an inner plate 1, a heat insulation layer 2 and an outer plate 3 from top to bottom, the heat insulation layer is clamped between the inner plate and the outer plate, a drainage hole 4 is formed in the drainage bottom plate, and the drainage hole penetrates through the drainage bottom plate, and the labyrinth-seal refrigerator drainage device is characterized in that: and a rubber seat 5 is arranged around the inner side of the drain hole, the rubber seat is clamped between the inner plate and the outer plate, and the rubber seat blocks the heat insulation layer exposed at the inner side of the drain hole.

The using method comprises the following steps: during the drainage, rivers flow to the drainage bottom plate on, flow from the wash port on the drainage bottom plate, and rivers are during through the heat preservation, because the heat preservation is by the shutoff of rubber seat, the rubber seat keeps apart heat preservation and water, and this kind of water just is difficult to contact the heat preservation, can not influence its cold insulation effect, has convenient to use's shortcoming, and wherein f is rivers flow direction.

Furthermore, a multi-layer ring-shaped groove structure 6 is arranged on the upper surface of the rubber seat, and a ring-shaped protruding structure 7 with a shape complementary to that of the ring-shaped groove structure is arranged below the inner plate.

Set up like this, rubber seat and inner panel between inseparabler, water-proof effects is better.

Furthermore, a multi-layer ring-shaped groove structure is arranged below the rubber seat, and a ring-shaped protruding structure with a shape complementary to the ring-shaped groove structure is arranged on the outer plate 3.

Set up like this, rubber seat and planking between inseparabler, water-proof effects is better.

Furthermore, one side of the rubber seat facing the heat insulation layer is fixedly provided with a plurality of elastic clamping pieces 8, and the elastic clamping pieces can be clamped between the inner plate and the outer plate.

Set up like this, can prevent that the rubber seat from appearing becoming flexible, break away from between the interior bottom plate.

Further, the elastic clamping pieces are paired, each pair of elastic clamping pieces comprises an upper elastic clamping piece 81 and a lower elastic clamping piece 82, each pair of upper elastic clamping piece and lower elastic clamping piece is in a shape of 'eight' rotation by 90 degrees, the narrow ends 9 of the pair of upper elastic clamping pieces and the pair of lower elastic clamping pieces are fixedly connected with the rubber seat, and the wide ends 10 of the pair of upper elastic clamping pieces and the pair of lower elastic clamping pieces respectively abut against the inner plate and the outer plate and have elastic force for supporting the inner plate and the outer plate.
