Abstract

The utility model relates to an air return channel for a refrigerator. The air return channel comprises a first air return channel and a second air return channel which are arranged in the vertical direction and connected in a clamping mode. By means of the technical scheme, the first air return channel and the second air return channel are connected in the clamping mode to form an air return channel whole body. The air return channel for the refrigerator is simple in structure, accurate in location and easy to assemble.

Description

Refrigerator is used air-return duct

Technical field

The utility model relates to a kind of refrigerator and uses air-return duct.

Background technology

At present, the air-return duct of refrigerator is made up of the air inlet and the air outlet at air channel body and body two ends, air channel, and air inlet links to each other with the air channel body through adhesive tape with air outlet; The processing technology of this connected mode is loaded down with trivial details, and assembly precision is poor, simultaneously because the air channel body is to extrude part; Its cross section can not conversion; Can only match with the shape of air inlet and air outlet, exist in the use and leak defectives such as bubble and return air is inhomogeneous easily, thereby cause evaporimeter frosting inhomogeneous; The defrosting heater inefficiency has been wasted energy resource consumption.

The utility model content

The purpose of the utility model is to provide a kind of refrigerator to use the air channel, and this air channel structure is simple, connects accurate positioning.

For realizing above-mentioned purpose, the utility model has adopted following technical scheme: described air-return duct comprises first, second air-return duct that is the above-below direction layout, and first, second air-return duct engaging links to each other.

The air-return duct integral body of the utility model is flat.

First air-return duct of the utility model is provided with draw-in groove and slot, and described second air-return duct is provided with buckle that matches with draw-in groove and the block that matches with slot.

The air-return duct air inlet end of the utility model is little, and air opening end is big.

Can be known that by technique scheme it is whole, simple in structure that the utility model forms air-return duct through first, second air-return duct engaging is linked to each other, accurate positioning is easy to assembling.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the explosive view of the utility model;

Fig. 3 is the A portion enlarged drawing of Fig. 1;

Fig. 4 is the B-B cutaway view of Fig. 1;

Fig. 5 is the C portion enlarged drawing of Fig. 4.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Use air-return duct like Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of refrigerator shown in Figure 5; Air-return duct comprises first, second air-

return duct

1,2 that is the above-below direction layout; 1,2 engagings of first, second air-return duct link to each other, and specifically are exactly that first air-return duct 1 is provided with draw-in groove 3 and is provided with buckle 4 that matches with draw-in groove 3 and the block 8 that matches with slot 7 with slot 7, the second air-return ducts 2; Locate earlier with slot 7 and block 8, combine to fix with draw-in groove 3 and buckle 4 again.

Preferred version as the utility model; Air-return duct integral body is flat, and the air inlet end 5 of air-return duct is little, and air opening end 6 is big; Be in order to realize return air efficiently like this; Make return air be directed at evaporator surface uniformly, make evaporimeter frosting even, promoted the operating efficiency of defrosting heater significantly.

Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
