Abstract

The utility model discloses a cover plate which is used for forming a wind-transporting and wind-returning channel of a refrigerator in a wind cooling refrigerator. A shell plate with a flanging is arranged on the point of the periphery which presents a quadrate shape basically; a column surface-shaped convex part is arranged on the middle part of the front surface of the shell plate from top to bottom, and a lining plate is arranged on the back surface of the convex part to form the superincumbent wind channel. The wind can be transported into an adjacent refrigerating chamber by the wind channel; an opening is arranged on the upper part of the lining plate, and the cold wind which is discharged by a fan can be transported through the opening. A grid-shaped wind-transporting opening and a grid-shaped wind-returning opening are arranged on the cover plate; an evaporator is contained in a hollow cavity which is surrounded by the flanging point of the cover plate and the inner liner of the refrigerator. The structure of the utility model is simple, and the utility model is suitable for being installed on the wall of a rear liner of a chamber of the refrigerator. The utility model has the advantages of small flow resistance and high heat exchange efficiency.

Description

The refrigerator air duct cover plate

The utility model discloses a kind of cover plate that constitutes the refrigerator supply air duct.

The air-supply structure of current refrigerator refrigerating chamber often adopts and sticks on the cover plate of air channel that the foam element that has complicated runner blows, this project organization complexity, and the assembling difficulty, manufacturing cost height, gas flow resistance in runner is big; And refrigerating chamber often adopts the vertical run return air of nature, and this return dynamic resistance is big, and return-air is mobile inhomogeneous in evaporimeter, has influenced the heat exchange effect of evaporimeter, has increased the energy consumption of refrigerator.

The purpose of this utility model be to design a kind of simple in structure, the air channel flow resistance is little, thereby improve the heat exchange effect, reduce the air channel cover plate of energy consumption of refrigerator.

For achieving the above object, the technical solution adopted in the utility model is: a kind of refrigerator air duct cover plate, it is characterized in that: cover plate is substantially the coverboard that there is flange at square periphery place, its positive middle part is the protuberance of cylinder shape from top to bottom, the back side at this position is provided with a liner plate, the lower end that constitutes top-down air channel between the two is the opening shape, circular open is arranged at the top of liner plate, the place ahead of above-mentioned opening the top of right protuberance and the air outlet that the position, both sides is provided with the grizzly bar shape that connects cover plate plate face, the bottom of cover plate and the both sides that are positioned at the air channel are provided with the return air inlet of the grizzly bar shape of run-through board face, and besieged city one can hold the chamber of evaporimeter between the periphery of cover plate and the inner container of icebox.

As shown from the above technical solution, the disclosed wind cooling refrigerator of the utility model has adopted the refrigerating chamber vertical ventilation, the air channel structure of refrigerating chamber water conservancy diversion return air just utilizes the method that adds liner plate to be partitioned into the vertical ventilation road at the cover plate back side, blow in refrigerating chamber by this vertical air channel; Adopt shutter at return air inlet place, cover plate front lower place, liner plate is connected with glue with associated components or welds, and is simple in structure, sealing is reliable, and water conservancy diversion is convenient in air-supply and return air path, and air-flow is evenly distributed through evaporimeter, be difficult for short circuit, improved the heat exchange effect, reduced energy consumption effectively.

Embodiment

Referring to Fig. 1～5, cover plate 10 is substantially the coverboard that there is flange at square periphery place, its positive middle part is the protuberance 11 of cylinder shape from top to bottom, the back side at this position is provided with a liner plate 20, constitute top-down air channel 30 between the two, the lower end in air channel 30 is the opening shape, circular open 21 is arranged at the top of liner plate 20, the place ahead of above-mentioned opening 21 the top of right protuberance 11 and the air outlet 22 of the grizzly bar shape that the position, both sides is provided with the run-through board face, the bottom of cover plate 10 and the both sides that are positioned at air channel 30 are provided with the return air inlet 23 of the grizzly bar shape of run-through board face, and besieged city one can hold the chamber of evaporimeter between the periphery of cover plate 10 and the inner container of icebox.

The bottom in the air channel 30 shown in Fig. 1 is up big and down small infundibulate, shown in the dotted line of the bottom among Fig. 1, air outlet 22, return air inlet 23 is the shutter form, with two side directions, adopts the venetian blind type structure under wind direction points to tiltedly, can realize easily cold wind is delivered to suitable position and direction, simultaneously, can avoid evaporimeter to be in the state that directly appears again, thereby clashing and breaking evaporimeter can avoid putting food the time.

The bottom of cover plate 10 is a nick shaped, and this gap portions and inner container of icebox form the air port of opening wide downwards, and it is positioned at uncovered inboard, 30 bottoms, above-mentioned air channel, as shown in Figure 6.

Referring to Fig. 6～7, cover plate 10 is positioned on the back courage wall of refrigerating chamber 41 of refrigerator 40, evaporimeter 50 is on this back courage wall and in the area of space that surrounds between cover plate 10 and liner plate 20 and back courage wall, through the cold wind of evaporimeter 50 refrigeration in ventilating fan 60 is blown into the air channel that cover plate 10 and liner plate 20 constitute, one road cold wind is in air outlet 22 enters refrigerating chamber 41, make temperature cooling in this refrigerating chamber 41, get back to the zone at evaporimeter 50 places then through return air inlet 23, thereby-heat transfer process of refrigerating chamber finished; Another road cold wind is in air channel 30 is blown into the chamber of refrigerating chamber 42 downwards, by of the suitable direction air-supply of air-supply distributor to refrigerating chamber 42, get back to the zone at evaporimeter 50 places through cover plate 10 and the air port 24 that wall of inner container and interlayer place constitute then, thereby finish the heat transfer process in the refrigerating chamber.
