[0047] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0049] Combine Figure 1-5 As shown, an embodiment of the present disclosure provides a refrigerator, which includes a box body 7, an inner tank 1, a refrigeration component 70 and an air duct 8.

[0050] The inner liner 1 is arranged in the box body 7, defining a storage chamber 11; the refrigeration assembly 70 is arranged between the box body 7 and the inner liner 1, and is arranged on the left and right sides of the storage chamber 11; the air duct 8 is arranged on the left and right sides of the storage chamber 11, including an air inlet 81 and an air outlet 82, the air inlet 81 is connected to the refrigeration assembly 70, and the air outlet 82 is connected to the storage chamber 11.

[0051] In the refrigerator provided by the embodiment of the present disclosure, the refrigeration assembly 70 is arranged on the left and right sides of the storage chamber 11, and the air duct 8 is also arranged on the left and right sides of the storage chamber 11, so that the foaming thickness of the rear side wall of the storage chamber 11 is reduced, which effectively releases the space on the rear side of the storage chamber 11, and increases the depth of the storage space of the storage chamber 11, making it convenient to store items that are long and difficult to divide, thereby meeting the needs of users.

[0052] The air duct 8 includes an air inlet 81 and an air outlet 82. The air inlet 81 is connected to the refrigeration chamber 71, and the air outlet 82 is connected to the storage chamber 11. When the first evaporator 3 and the second evaporator 4 in the left and right refrigeration chambers 71 generate cold air, the cold air enters the air duct 8 from the air inlet 81, flows through the air outlet 82 to the storage chamber 11, and cools the storage chamber 11.

[0053] Alternatively, as Figure 1 As shown, the refrigeration assembly 70 includes a refrigeration chamber 71, a first evaporator 3 and a second evaporator 4. The refrigeration chamber 71 is arranged on the left and right sides of the storage chamber 11; the first evaporator 3 is arranged in the left refrigeration chamber 71; and the second evaporator 4 is arranged in the right refrigeration chamber 71.

[0054] The refrigeration assembly 70 is disposed on the left and right sides of the storage chamber 11. The refrigeration chamber 71 is disposed on the left and right sides of the storage chamber 11. The first evaporator 3 is disposed within the left refrigeration chamber 71, located on the left side of the storage chamber 11. The second evaporator 4 is disposed within the right refrigeration chamber 71, located on the right side of the storage chamber 11. When the first evaporator 3 and the second evaporator 4 generate cold air, the cold air fills the left and right refrigeration chambers 71. The cold air enters the air duct 8 through the air inlet 81 and flows through the air outlet 82 to the storage chamber 11, thereby cooling the storage chamber 11.

[0055] Alternatively, as Figure 1 As shown, the storage chamber 11 includes a first chamber 12, a second chamber 13 and a third chamber 14. The first chamber 12 and the second chamber 13 are arranged side by side, and the third chamber 14 is located above the first chamber 12 and the second chamber 13. The air duct 8 includes a first air duct 83 and a second air duct 84. The first air duct 83 is arranged on the left side of the first chamber 12 and the third chamber 14 and is connected to the left refrigeration chamber 71; the second air duct 84 is arranged on the right side of the second chamber 13 and the third chamber 14 and is connected to the right refrigeration chamber 71.

[0056] The first evaporator 3 is arranged in the left refrigeration chamber 71, and the second evaporator 4 is arranged in the right refrigeration chamber 71. The first evaporator 3 cools the first chamber 12 and the third chamber 14 through the first air duct 83, and the second evaporator 4 cools the second chamber 13 and the third chamber 14 through the second air duct 84.

[0057] Alternatively, as Figure 1 、 Figure 2 and Figure 4 As shown, the first air duct 83 and / or the second air duct 84 protrude into the third compartment 14 relative to the side wall of the third compartment 14, the air outlet 82 includes a first air outlet, and the first air outlet of the first air duct 83 and / or the second air duct 84 includes a front air outlet 85 and a rear air outlet 86 that are arranged opposite to each other, the front air outlet 85 is arranged toward the front side of the third compartment 14, and the rear air outlet 86 is arranged toward the rear side of the third compartment 14.

[0058] This application takes the example that both the first air duct 83 and the second air duct 84 are provided with a first air outlet. The first air outlets of the first air duct 83 and the second air duct 84 connect the first air duct 83 and the second air duct 84 with the third chamber 14 for cooling the third chamber 14. The first air outlets include a front air outlet 85 and a rear air outlet 86. The first air outlet of the first air duct 83 is located on the left side wall of the third chamber 14, and the first air outlet of the second air duct 84 is located on the right side wall of the third chamber 14. When the front air outlet 85 and the rear air outlet 86 are arranged opposite to each other, the front air outlet 85 is arranged toward the front side of the third chamber 14, and the rear air outlet 86 is arranged toward the rear side of the third chamber 14. The front air outlet 85 and the rear air outlet 86 discharge air together, forming a surround-type air supply method to supply air for cooling the third chamber 14. When the air outlet 82 of the first air duct 83 and the air outlet 82 of the second air duct 84 discharge air at the same time, the air supply in the third chamber 14 is more uniform.

[0059] The front air outlet 85 and the rear air outlet 86 may also be arranged in a staggered manner, with the front air outlet 85 supplying air toward the front side of the third compartment 14 and the rear air outlet 86 supplying air toward the rear side of the third compartment 14. When the front air outlet 85 and the rear air outlet 86 are staggered, the air supply heights of the front air outlet 85 and the rear air outlet 86 are different, so that more locations in the third compartment 14 can be cooled.

[0060] The number of the front air outlet 85 and the rear air outlet 86 can be one or more. This application takes the example that the number of the front air outlet 85 and the rear air outlet 86 are both more than one.

[0061] Alternatively, as Figure 2 and Figure 4 As shown, there are multiple front air outlets 85 and multiple rear air outlets 86 , and the multiple front air outlets 85 and the multiple rear air outlets 86 are sequentially spaced apart along the height direction of the third compartment 14 .

[0062] The front air outlet 85 and the rear air outlet 86 are arranged opposite to each other, and there are multiple of them. They are all arranged in sequence along the height direction of the third compartment 14. Therefore, the front air outlet 85 and the rear air outlet 86 at the same height are arranged opposite to each other. When the front air outlet 85 and the rear air outlet 86 at this height supply air together, a surround air supply is formed at this height position in the compartment. The front air outlet 85 and the rear air outlet 86 at multiple heights supply air to the third compartment 14 together, making the cold air circulation in the third compartment 14 more uniform, thereby improving the cooling effect of the third compartment 14.

[0063] Alternatively, as Figure 4 As shown, the area of the front air outlet 85 is smaller than the area of the rear air outlet 86 .

[0064] The front air outlet 85 and the rear air outlet 86 are arranged opposite to each other, the front air outlet 85 is arranged toward the front side of the third compartment 14, and the rear air outlet 86 is arranged toward the rear side of the third compartment 14. Therefore, the front air outlet 85 is close to the opening of the third compartment 14. Compared with the rear air outlet 86, after the front air outlet 85 delivers air, the air circulation path is shorter and relatively less cold air is required. When the area of the front air outlet 85 is smaller than that of the rear air outlet 86, the air volume delivered by the front air outlet 85 is less than that delivered by the rear air outlet 86, which can also reduce the loss of cold air at the opening of the third compartment 14, improve the refrigeration efficiency, and reduce the energy consumption of the refrigerator.

[0065] Optionally, the air outlet 82 further includes a second air outlet. The first air outlet connects the air duct 8 with the third chamber 14 , and the second air outlet connects the first air duct 83 with the first chamber 12 and the second air duct 84 with the second chamber 13 .

[0066] Alternatively, as Figure 1 As shown, a first cooling air outlet 121 is provided on the side wall of the first compartment 12 to communicate between the second air outlet portion of the first air duct 83 and the first compartment 12 ; a second cooling air outlet 131 is provided on the side wall of the second compartment 13 to communicate between the second air outlet portion of the second air duct 84 and the second compartment 13 .

[0067] The second air outlet portion of the first air duct 83 connects the first air duct 83 with the first chamber 12 for cooling the first chamber 12. The second air outlet portion of the first air duct 83 includes a first cooling air outlet 121. When the first evaporator 3 generates cold air, the cold air enters the first air duct 83 through the air inlet portion 81, passes through the first air duct 83, and flows into the first chamber 12 through the first cooling air outlet 121, thereby improving the cooling effect of the first chamber 12.

[0068] The second air outlet of the second air duct 84 connects the second air duct 84 with the second chamber 13 for cooling the second chamber 13. The second air outlet of the second air duct 84 includes a second cooling air outlet 131. When the second evaporator 4 generates cold air, the cold air enters the second air duct 84 through the air inlet 81, passes through the second air duct 84, and flows into the second chamber 13 through the second cooling air outlet 131, thereby improving the cooling effect of the second chamber 13.

[0069] The number of the first cooling air outlet 121 and the second cooling air outlet 131 can be one or more. This application takes the case where the number of the first cooling air outlet 121 and the second cooling air outlet 131 are both more than one as an example.

[0070] Alternatively, as Figure 2 As shown, the refrigerator further includes a first return air duct 9 and a second return air duct. The first return air duct 9 and the second return air duct are arranged on the rear wall of the box body 7. One end of the first return air duct 9 and the second return air duct are connected to the third chamber 14, and the other end is connected to the left and right refrigeration chambers 71 respectively, so as to circulate cold air between the third chamber 14 and the left and right refrigeration chambers 71.

[0071] The first return air duct 9 and the second return air duct are respectively arranged between the third chamber 14 and the left and right refrigeration chambers 71. When cold air enters the third chamber 14 through the first air duct 83 and the second air duct 84, it cools the items placed in the third chamber 14. After cooling, the cold air temperature rises and returns to the left and right refrigeration chambers 71 through the first return air duct 9 and the second return air duct, respectively, to realize cold air circulation between the third chamber 14 and the left and right refrigeration chambers 71, which can improve the cooling efficiency of the third chamber 14.

[0072] It can be understood that the first return air duct 9 and the second return air duct can also be arranged between the side wall of the box body 7 and the inner tank 1, so that the foaming thickness of the rear side wall of the storage chamber 11 is reduced, effectively releasing the space on the rear side of the storage chamber 11, and increasing the depth of the storage space of the storage chamber 11.

[0073] Alternatively, as Figure 2 and Figure 3 As shown, the first return air duct 9 includes a first return air port 91 connected to the left refrigeration chamber 71, and the second return air duct includes a second return air port connected to the right refrigeration chamber 71. The distance between the highest point of the first return air port 91 and the lowest point of the first evaporator 3, and the distance between the highest point of the second return air port and the lowest point of the second evaporator 4 are a mm, where a ≥ 0.

[0074] The first return air duct 9 connects the left refrigeration chamber 71 with the third compartment 14. The first return air inlet 91 is located at the position where the first return air duct 9 connects with the left refrigeration chamber 71, and is relatively close to the first evaporator 3. The highest point of the first return air inlet 91 is set lower than the lowest point of the first evaporator 3. This can prevent the first return air inlet 91 from cooling down when the first evaporator 3 generates cold air, thereby preventing frost from blocking the first return air inlet 91. The second return air duct connects the right refrigeration chamber 71 with the third compartment 14. The second return air inlet is located at the position where the second return air duct connects with the right refrigeration chamber 71, and is relatively close to the second evaporator 4. The highest point of the second return air inlet is set lower than the lowest point of the second evaporator 4. This can prevent the second return air inlet from cooling down when the second evaporator 4 generates cold air, thereby preventing frost from blocking the second return air inlet.

[0075] The distance between the highest point of the first return air outlet 91 and the lowest point of the first evaporator can be 0.5mm, 1mm, 1.5mm, 2mm and 2.5mm, and the distance between the highest point of the second return air outlet and the lowest point of the second evaporator 4 can be 0.5mm, 1mm, 1.5mm, 2mm and 2.5mm.

[0076] Alternatively, as Figure 1 As shown, the refrigerator further includes a first damper 92 and a second damper 93. The first damper 92 is disposed in the first air duct 83 relative to the connection between the first compartment 12 and the third compartment 14. The second damper 93 is disposed in the second air duct 84 relative to the connection between the second compartment 13 and the third compartment 14.

[0077] After the first evaporator 3 generates cold air, the cold air enters the first air duct 83 and the second air duct 84 from the refrigeration chamber 71, enters the first compartment 12 along the first refrigeration air outlet 121, thereby cooling the first compartment 12, and enters the second compartment 13 along the second refrigeration air outlet 131, thereby cooling the second compartment 13. A first damper 92 is provided between the first compartment 12 and the third compartment 14, and a second damper 93 is provided between the second compartment 13 and the third compartment 14. When the third compartment 14 requires cooling, the first damper 92 and / or the second damper 93 are opened to allow the cold air to approach the third compartment 14. When the third compartment 14 does not require cooling, the first damper 92 and the second damper 93 are closed to prevent the cold air from entering. This avoids the loss of cold air, reduces the energy consumption of the refrigerator, and improves the cooling efficiency.

[0078] Alternatively, as Figure 1 As shown, the refrigerator further includes a first fan 94 and a second fan 95 . The first fan 94 is arranged on the left side of the first chamber 12 and in the first air duct 83 ; the second fan 95 is arranged on the right side of the second chamber 13 and in the second air duct 84 .

[0079] The first and second fans 94, 95 accelerate the flow of air. After the first and second evaporators 3, 4 generate cold air, it enters the first and second air ducts 83, 84 through the air inlet 81. The provision of the first and second fans 94, 95 allows the cold air to flow more quickly within the first and second air ducts 83, 84, allowing it to more quickly enter the first compartment 12 through the first cooling outlet 121 and the second compartment 13 through the second cooling outlet 131. This accelerates the cooling of the first and second compartments 12, 13, and improves the cooling efficiency of the first and second compartments 12, 13. Furthermore, the first and second fans 94, 95 are respectively disposed between the air inlet 81 and the first damper 92, and between the air inlet 81 and the second damper 93. This accelerates the flow of cold air toward the third compartment 14, accelerating its entry into the third compartment 14 through the front and rear outlets 85, 86, accelerating the cooling of the third compartment 14, and improving the cooling efficiency of the third compartment 14.

[0080] Alternatively, as Figure 5 As shown, the refrigerator also includes a compressor 2, which is provided with an inlet 21; wherein, the first evaporator 3 and the second evaporator 4 are arranged in parallel, and one end of the first evaporator 3 and the second evaporator 4 are connected to the inlet 21; the refrigerant flows from the first evaporator 3 and / or the second evaporator 4 into the compressor 2.

[0081] The first evaporator 3 and the second evaporator 4 are arranged in parallel, so that the first evaporator 3 and the second evaporator 4 can cool separately without affecting each other, so that the temperature fluctuation of the refrigeration space corresponding to the first evaporator 3 and the second evaporator 4 is small, meeting the needs of users.

[0082] Alternatively, as Figure 5 As shown, the refrigerator further includes an air return pipe 6 , one end of which is connected to the inlet 21 of the compressor 2 , and the other end of which is connected to the first evaporator 3 and the second evaporator 4 .

[0083] The return air pipe 6 connects the first evaporator 3 with the compressor 2, and connects the second evaporator 4 with the compressor 2, and transmits the evaporated gas in the first evaporator 3 and the second evaporator 4 to the compressor 2 to continue the cycle of the refrigeration process.

[0084] Optionally, the length of the return air pipe 6 ranges from 2 m to 2.5 m.
