[0023] The present invention discloses a refrigerator with an embedded multi-dimensional air cooling circulation structure. An implementation manner of the present invention is described in detail below in conjunction with the accompanying drawings.

[0024] Combination Figure 1 and Figure 2 As shown, a refrigerator with an embedded multi-dimensional air-cooling circulation structure includes a cabinet body 1, a cover body 2, an evaporator 6 and an air duct assembly. An inner tank is arranged in the cabinet body 1. The right bottom of the inner tank is stepped to accommodate the compressor. The right wall of the inner tank is provided with an installation opening. Figure 3 and Figure 4 As shown, the air duct assembly includes an air duct component 11 and an air duct cover plate 3. The air duct component 11 is arranged at the installation opening and embedded in the foaming layer between the inner tank and the inner wall of the cabinet 1 through the installation opening, which can reduce the storage space occupied by the inner tank and improve the volume utilization rate of the inner tank. There is a gap between the air duct component 11 and the bottom wall of the inner tank. The air duct cover plate 3 is detachably fixed to the top of the inner tank step by a buckle and is connected to the air duct component 11. An accommodating cavity is formed between the air duct cover plate 3, the air duct component 11 and the inner tank step. A water receiving tray 7 is provided on the bottom wall of the accommodating cavity. The water receiving tray 7 is connected to the top of the inner tank step, and part of the bottom surface of the water receiving tray 7 is tightly fitted with the top surface of the inner tank step. The duct foam 5 is provided in the accommodating cavity, and the duct foam 5 is located between the air duct cover plate 3 and the top of the evaporator 6. In this embodiment, the thickness of the air duct foam 5 is not less than 15 mm. The air duct foam 5 is placed on the top of the evaporator 6 to prevent the air duct cover plate 3 adjacent to the evaporator 6 from frosting when the refrigerator is running. One end of the air duct foam 5 has a protrusion, which can be used to position the evaporator 6 to prevent the evaporator 6 from shaking during transportation and improve the stability of the evaporator 6. The air duct cover plate 3 can press the evaporator 6 through the air duct foam 5 to further improve the stability of the evaporator 6.

[0025] The bottom wall of the water receiving tray 7 is divided into a first connection part and a second connection part, and the first connection part is located on the left side of the second connection part. The first connection part is plate-shaped and inclined toward the second connection part, and the angle between the first connection part and the horizontal plane is at least 5°. The evaporator 6 is arranged on the first connection part of the accommodating chamber, and the evaporator 6 is inclined along with the first connection part, which can ensure that the water on the fins of the evaporator 6 can be discharged smoothly when the inner tank enters the defrosting cycle. There is at least 33mm between the evaporator 6 and the fan component 11 to prevent the evaporator 6 from being too close to the fan, causing the fan component 11 to freeze and stop, effectively reducing the risk of freezing and stopping of the fan. The second connection part is funnel-shaped, with a drainage hole in the middle, and the bottom of the second connection part is also connected to a drainage pipe connected to the drainage hole. An S-shaped defrosting heating pipe is arranged at the bottom of the evaporator 6, and the defrosting heating pipe extends to the gap between the fan component 11 and the inner tank. The defrosting heating tube can ensure that when the cabinet 1 enters the defrosting cycle, the heat of the defrosting heating tube can be radiated into the fan component 11 for defrosting.

[0026] Combination Figure 5 and Figure 6 As shown, the bottom of the cover body 2 is provided with a first air guide groove 12 and a plurality of second air guide grooves 13, the bottom of the first air guide groove 12 is arranged in the left-right direction, the second air guide grooves 13 are arranged on both sides of the first air guide groove 12, and the bottom of each second air guide groove 13 is gradually inclined toward the inside of the cover body 2 along the direction from the first air guide groove 12 to the direction away from the first air guide groove 12. The wind mechanism component 11 has an air outlet located on the upper side of the inner liner, and the air outlet includes a first air outlet 9 and a second air outlet 10, the first air outlet 9 faces the first air guide groove 12, and the angle between the first air outlet 9 and the horizontal plane is 60°, and the second air outlet 10 is parallel to the horizontal plane. A plurality of third air guide grooves 14 are provided on the side wall of the inner liner, and the bottom of each third air guide groove 14 is arranged in the up-down direction. The upper end and the lower end of the bottom of each third air guide groove 14 have a gentle slope in an inclined shape. The bottom wall of the inner container is provided with a plurality of fourth air guide grooves 15, and the bottoms of the fourth air guide grooves 15 are arranged in the left-right direction. The air duct cover plate 3 has a return air port 4 located at the lower side of the inner container, and the return air port 4 is parallel to the bottom wall of the inner container.

[0027] like Figure 7As shown, after the cabinet 1 is powered on, the evaporator 6 starts to cool, the fan in the fan component 11 starts, and the air in the inner tank is sucked into the return air port 4 from left to right. After the sterilization and deodorization block 8 is provided in the accommodating cavity for sterilization and deodorization, the air is cooled down through the evaporator 6 and becomes low-temperature cold air. The low-temperature cold air passes through the air duct in the fan component 11 and blows out from the first air outlet 9 and the second air outlet 10. The wind from the first air outlet 9 blows upward at an angle of 60° to the first air guide groove 12, and then the cold air enters the second air guide groove 13 from both sides of the first air guide groove 12. Then the cold air flows downward along the third air guide groove 14 of the inner tank to cool the air in the inner tank. The second air outlet 10 supplies air to the inner tank in a direction parallel to the bottom wall of the inner tank to ensure the temperature uniformity and cooling efficiency in the inner tank. The air in the inner tank that has been cooled down passes through the return air port 4 and the evaporator 6 again to complete the air circulation. The temperature in the inner tank continues to decrease with the temperature of the evaporator 6 until it reaches the set temperature. The present invention utilizes the first air guide groove 12, the second air guide groove 13, the third air guide groove 14 and the fourth air guide groove 15 to form a gap between the inner tank and the stored items, thereby ensuring smooth flow of gas and improving the refrigeration effect.

[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
