Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 The utility model provides a refrigeration air duct of a double-door air-cooled refrigerator, comprising an air duct cover 1 and an outer frame 9. The air duct cover 1 is engaged with the inner wall of the outer frame 9. The top of the front of the air duct cover 1 is provided with a front air outlet 3. The bottom of the front of the air duct cover 1 is provided with a front air outlet 2 7 and a front air outlet 3 8 in sequence from top to bottom. The top and bottom blow out air from the front. The two sides of the middle of the air duct cover 1 are provided with a side air outlet 4, a side air outlet 2 5 and a side air outlet in sequence from top to bottom. Three 6, the air is blown out from the side in the middle, connecting seats 10 are fixedly embedded on both sides of the top and both sides of the bottom of the air duct cover 1, one side of the inner wall of the four connecting seats 10 is fixedly connected with a spring piece 11, one end of the four spring pieces 11 is fixedly connected with a card block 12, and both sides of the top of the inner wall of the outer frame 9 and both sides of the bottom of the inner wall are provided with a card slot 13, and the front of the four connecting seats 10 is provided with a through hole 15, and the inner walls of the four through holes 15 are plugged with a pressing column 16 for assembling the air duct cover 1.

[0028] When in use, the air outlet on the air duct corresponds to each shelf or drawer, that is, each shelf and drawer of the box body is provided with an air supply outlet 2, the top shelf is provided with a front air outlet, and each of the two bottom drawers in the back duct is provided with a front air outlet. The shelves corresponding to the second, third and fourth layers are provided with side air outlets on the refrigeration duct. By combining the front air outlet with the side air outlet, the problem of uneven air supply in the back duct is solved, thereby avoiding excessive air supply above the middle shelves of the box body, and avoiding the cold air directly blowing towards the food, causing freezing of the food.

[0029] An air supply vent 2 is provided at the top of the back side of the air duct cover 1 to supply cold air downward. The width of the front air outlet 1 3 is 100mm-150mm, and the height is 10mm-15mm. The width of the front air outlet 2 7 and the front air outlet 3 8 are both 60mm-80mm, and the height is 8mm-10mm. The height of the side air outlet 1 4, the side air outlet 2 5 and the side air outlet 3 6 are all 10mm-20mm, and the depth direction is 10mm.

[0030] When in use, the evaporator and the freezing fan of the double-door air-cooled refrigerator are placed in the freezer duct, and the refrigerated air supply damper is placed on the top of the freezer duct. The purpose of supplying air to the refrigerator compartment is achieved by opening and closing the damper. Since the air supply outlet 2 of the refrigerated air supply damper is located at the top of the back, the first-layer air outlet is set in the center of the front of the air duct cover 1. The second, third and fourth layers with larger air volume are set to side air supply mode. The front air supply mode can still be selected at the bottom due to weaker air volume.

[0031] One end of the block 12 is engaged with the inner wall of the slot 13 to play a locking role. One end of the two pressing columns 16 located at the same height is fixedly connected to a linkage plate 17 for easy operation. A bevel groove 14 is provided in the middle of the block 12, and openings 18 are provided on both sides of the outer frame 9 corresponding to the side air outlet 1 4, the side air outlet 2 5 and the side air outlet 3 6 to prevent affecting the air outlet. The top and bottom of both sides of the outer frame 9 are fixedly connected with lugs 20, and the surface of the lugs 20 is provided with two fixing holes 21 for installation. The top and bottom of the front of the air duct cover 1 are fixedly connected with handles 19 for easy hand-held movement.

[0032] During use, fasteners are used to fix the outer frame 9 in the refrigerator compartment at the fixing holes 21 of the lugs 20. When assembling the air duct cover 1, the two linkage plates 17 on its surface are pressed to drive the pressing column 16 to move. With the cooperation of the inclined groove 14, the block 12 can be squeezed to retract it into the connecting seat 10. At this time, the handle 19 is held to clamp the air duct cover 1 into the inner wall of the outer frame 9. After loosening the linkage plate 17, the block 12 will be clamped into the slot 13 of the outer frame 9 under the action of the spring 11, which plays a locking role to prevent the air duct cover 1 from falling off. The opening 18 provided ensures that the outer frame 9 will not affect the side air outlet of the air duct cover 1.

[0033] The utility model discloses a refrigerator duct for cooling the refrigerator by opening and closing the air door, wherein the evaporator and the freezing fan of the refrigerator are placed in the air duct of the freezer compartment, and the air supply door of the refrigerator compartment is placed on the top of the freezer compartment air duct. The purpose of supplying air to the refrigerator compartment is achieved by opening and closing the air door. Since the air supply door of the refrigerator compartment is located at the top of the back, the air outlet of the first layer is arranged at the center of the front of the air duct cover 1, and the second, third and fourth layers with larger air volume are arranged with side air supply mode. The front air supply mode can still be selected because the air volume at the bottom is weaker. The advantage of this air supply through the back duct is that the upper and lower parts of the refrigerator duct are front air outlets, and the middle part is left and right air outlets. The front air outlet is combined with the side air outlet to form a surround three-dimensional air supply mode, which can effectively reduce the room temperature difference of the refrigerator compartment, improve the temperature uniformity, and reduce the energy consumption of the whole machine. The air outlet on the air duct corresponds to each shelf or drawer of the box body, that is, each shelf and drawer of the box body is provided with an air supply port, the top shelf is provided with a front air outlet, and the top shelf is provided with a front air outlet. The second, third and fourth shelves are provided with side air outlets on the refrigeration duct. By combining the front air outlet with the side air outlet, the problem of uneven air supply through the back duct is solved, thereby preventing the air supply above the middle shelves of the box from being too strong, and the cold air directly blowing onto the food, causing the food to freeze. The outer frame 9 is arranged in the refrigeration chamber of the refrigerator. When the air duct cover 1 is assembled, the two linkage plates 17 on its surface are pressed to drive the pressing column 16 to move under the cooperation of the inclined groove 14, and the card block 12 can be squeezed to retract it into the connecting seat 10. At this time, the air duct cover 1 is snapped into the inner wall of the outer frame 9. After loosening the linkage plate 17, the card block 12 will be snapped into the card slot 13 of the outer frame 9 under the action of the spring piece 11, which plays a locking role to prevent the air duct cover 1 from falling off and improve the sealing of the connection. The assembly efficiency is high. The air duct cover 1 can be disassembled by pressing the two linkage plates 17 again, which is convenient for maintenance.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
