[0002] At present, refrigerators include refrigeration refrigerators and air-cooled refrigerators. Air-cooled refrigerators can be divided into single-system and multi-system refrigerators according to the number of evaporators used. Multi-system refrigerators usually have separate refrigeration and return air for the refrigerator and freezer. Their air duct structure is relatively simple, and usually no built-in air duct is required in the foam layer of the cabinet. The most common single-system refrigerator is to supply air from the freezer to the refrigerator, and some are equipped with a variable temperature chamber. The air duct structure of this three-chamber single system is relatively complex. The return air duct of existing refrigerators is mostly made of plastic, and most of them are assembled by splicing multiple parts. The mold investment is large, and the assembly process of the refrigerator during production is cumbersome, time-consuming, and inefficient. At the same time, due to the splicing and assembly of multiple parts, the anti-leakage measures are also required to be high, which makes the material cost and production process cost high, which is not conducive to the control of production cost.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:
[0005] The existing variable temperature air duct is arranged at the rear side of the variable temperature chamber. Since the lowest temperature of the variable temperature chamber can reach minus 20 degrees Celsius, in order to avoid condensation on the back plate of the refrigerator, a thicker back foam layer is required, resulting in a smaller space in the variable temperature chamber.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0044] Combination Figures 1 to 6 As shown, the embodiment of the present disclosure provides an integrated air duct structure for a refrigerator, the integrated air duct structure for a refrigerator includes: a front air duct seat 10, a center air duct seat 20 and a rear air duct seat 30, the rear air duct seat 30 is extended vertically; the center air duct seat 20 is arranged at the front side of the rear air duct seat 30 and the center air duct seat 20 is connected to the rear air duct seat 30, and a refrigerated supply air duct 41 and a refrigerated return air duct 42 are constructed between the rear air duct seat 30 and the center air duct seat 20; the front air duct seat 10 is arranged at the front side of the center air duct seat 20 and the front air duct seat 10 is connected to the center air duct seat 20, and a variable temperature supply air duct 51 and a variable temperature return air duct 52 are constructed between the front air duct seat 10 and the center air duct seat 20; wherein, the variable temperature return air duct 52 is arranged in close contact with the refrigerated return air duct 42 and the variable temperature return air duct 52 is located at the front side of the refrigerated return air duct 42.
[0045] By adopting the embodiment of the present disclosure, an independent refrigerated supply air duct 41 and a refrigerated return air duct 42 can be formed by connecting the rear air duct seat 30 with the middle air duct seat 20, and an independent variable temperature supply air duct 51 and a variable temperature return air duct 52 can be formed by connecting the front air duct seat 10 with the middle air duct seat 20. The temperatures of the refrigerated room and the variable temperature room can be independently controlled, making the temperatures of the two areas more precise and stable.
[0046] By independently setting the refrigerated return air duct 42 and the variable temperature return air duct 52, the air in the refrigerated room will not mix with the air in the variable temperature room in the return air duct, and the return air duct can be prevented from being blocked by frost due to the large temperature difference between the refrigerated return air and the variable temperature return air. In addition, the middle air duct seat 20 separates the refrigerated return air duct 42 from the variable temperature return air duct 52. Since the middle air duct seat 20 is an integrated structure, not a spliced structure, the refrigerated return air duct 42 and the variable temperature return air duct 52 can be prevented from being mixed through the gap of the middle air duct seat 20.
[0047] The air supply and return air ducts of the refrigerator can be formed by assembling the front air duct seat 10, the middle air duct seat 20 and the rear air duct seat 30, which effectively reduces the number of assembly parts and improves assembly efficiency.
[0048] The lowest internal temperature of the conventional variable temperature return air duct 52 can reach minus twenty degrees. When the variable temperature return air duct 52 is arranged at the back of the refrigerator, a thicker insulation layer needs to be arranged between the variable temperature return air duct 52 and the back plate to avoid condensation on the back plate of the refrigerator. The thickness of the insulation layer of the variable temperature return air duct 52 is greater than the thickness of the insulation layer of the refrigerated return air duct 42, which will result in a smaller space of the variable temperature chamber. By arranging the variable temperature return air duct 52 at the front side of the refrigerated return air duct 42, it is possible to avoid condensation on the back plate of the refrigerator without arranging a thicker insulation layer, thereby increasing the space of the variable temperature chamber. In addition, the variable temperature return air duct 52 can transfer part of the heat to the refrigerated return air duct 42, thereby reducing the temperature of the air in the refrigerated return air duct 42, improving the utilization rate of heat, and thereby reducing the energy consumption of the refrigerator.
[0049] Optionally, the first end of the variable temperature air supply duct 51 is suitable for communicating with the refrigeration compartment 64 of the refrigerator, and the second end of the variable temperature air supply duct 51 is suitable for communicating with the variable temperature compartment, so that the cold air in the refrigeration air supply duct flows into the variable temperature compartment; the first end of the refrigeration air supply duct 41 is suitable for communicating with the variable temperature compartment, and the second end of the refrigeration air supply duct 41 is suitable for communicating with the refrigeration compartment, so that the cold air in the variable temperature compartment flows into the refrigeration compartment.
[0050] By adopting the embodiment of the present disclosure, by connecting the first end of the variable temperature air supply duct 51 to the refrigeration compartment 64 of the refrigerator, and connecting the second end of the variable temperature air supply duct 51 to the variable temperature compartment, the cold air in the refrigeration air supply duct can flow directly into the variable temperature compartment, and the temperature of the variable temperature compartment can be quickly adjusted as needed, allowing the user to quickly adjust the temperature of the variable temperature compartment according to different food storage requirements. By using the cold air in the variable temperature compartment to supply the refrigeration compartment, the length of the refrigeration air supply duct 41 can be effectively shortened, reducing unnecessary air flow and energy loss, thereby improving the energy efficiency of the refrigerator.
[0051] Optionally, the integrated air duct structure for the refrigerator further includes: a first air door, which is arranged in the refrigeration air supply duct 41 and is used to control the opening and closing of the refrigeration air supply duct 41.
[0052] In this way, by setting the first damper, the first damper can accurately control the opening and closing degree of the refrigeration air supply duct 41, thereby adjusting the air intake of the refrigeration chamber. This helps to maintain the stability of the temperature in the refrigeration chamber and avoid the influence of temperature fluctuations on the quality of food. When the refrigeration chamber does not need a large amount of cold air, the air supply can be reduced by closing the first damper, thereby reducing energy consumption.
[0053] Optionally, the integrated air duct structure for the refrigerator further includes: a second air door, the second air door is arranged in the variable temperature air supply duct 51, and the second air door is used to control the opening and closing of the variable temperature air supply duct 51.
[0054] In this way, by setting the second damper, the second damper can accurately control the opening and closing degree of the variable temperature air supply duct 51, thereby adjusting the air intake of the variable temperature chamber. This helps to maintain the stability of the temperature in the variable temperature chamber and avoid the impact of temperature fluctuations on food quality. When the variable temperature chamber does not need a large amount of cold air, the first damper can be closed to reduce the air supply volume, thereby reducing energy consumption.
[0055] Optionally, the vertical projection of the refrigerated air supply duct 41 is located within the projection of the temperature variable air supply duct 51 .
[0056] With the disclosed embodiment, the vertical projection of the refrigerated air supply duct 41 is located within the projection of the variable temperature air supply duct 51, that is, the refrigerated air supply duct 41 is located directly above the variable temperature air supply duct 51, and the air blown out of the variable temperature air supply duct 51 can flow directly to the refrigerated air supply duct 41, thereby reducing the flow resistance and allowing the air in the refrigeration compartment 64 to quickly flow into the cold storage compartment to quickly adjust the temperature of the cold storage compartment.
[0057] Optionally, the flow area of the variable temperature air supply duct 51 is larger than the flow area of the refrigerated air supply duct 41 .
[0058] By adopting the embodiment of the present disclosure, by setting the flow area of the variable temperature air supply duct 51 to be larger than the flow area of the refrigerated air supply duct 41, more cold air can flow into the variable temperature chamber, accelerating the temperature adjustment, and allowing the variable temperature chamber to quickly reach the preset temperature. At the same time, the larger flow area of the variable temperature air supply duct 51 can ensure that the air is more evenly distributed in the variable temperature chamber, which helps to avoid the situation where the temperature is too high or too low in some areas. In addition, when the temperature of both the variable temperature chamber and the cold storage chamber needs to be adjusted, the larger flow area allows more cold air to flow in or out quickly, and while the temperature of the variable temperature chamber is quickly adjusted, part of the air can be sent into the cold storage chamber through the refrigerated air supply duct 41 to meet the refrigeration demand of the cold storage chamber.
[0059] Optionally, the variable temperature return air duct 52 has a variable temperature return air outlet 521, and the variable temperature return air outlet 521 is arranged vertically inclined.
[0060] Using the embodiment of the present disclosure, combined with Figure 1 and Figure 5 As shown in , by setting the variable temperature chamber return air outlet 521, the variable temperature chamber return air outlet 521 is suitable for communicating with the variable temperature chamber, so that the air in the variable temperature chamber can flow into the variable temperature return air duct 52 through the variable temperature chamber return air outlet 521. By setting the variable temperature chamber return air outlet 521 vertically tilted, on the one hand, the return air area of the variable temperature chamber return air outlet 521 can be increased, and the return air volume can be increased. On the other hand, the air flow can be guided to make the return air smoother, which helps to reduce the formation of vortices and dead corners, thereby improving the efficiency and uniformity of air flow, and further reducing the noise of air flow, and improving the user experience.
[0061] Combination Figure 1 and Figure 6 As shown in, optionally, the variable temperature return air duct 52 has a variable temperature air outlet 522, and the variable temperature air outlet 522 is suitable for communicating with the refrigeration chamber 64; the refrigeration return air duct 42 has a refrigeration chamber return air outlet 421 and a refrigeration air outlet 422, and the refrigeration air outlet 422 is suitable for communicating with the refrigeration chamber 64; wherein the variable temperature air outlet 522 is located on one side of the refrigeration air outlet 422.
[0062] In this way, by setting the variable temperature air outlet 522 and the refrigerated air outlet 422 separately, the temperature interference between the two can be reduced. Compared with the setting method of using one return air outlet for the refrigerated return air duct 42 and the variable temperature return air duct 52, the cross-flow of the refrigerated return air and the frozen return air can be avoided, and the return air outlet can be prevented from being blocked by frost due to the large temperature difference between the refrigerated return air and the variable temperature return air.
[0063] Combination Figure 1 As shown in , optionally, the variable temperature return air duct 52 is located on one side of the middle air duct seat 20 .
[0064] In this way, the space at the side of the temperature changing chamber can be fully utilized, which can reduce the thickness of the foaming layer on the one hand and increase the space of the temperature changing chamber on the other hand.
[0065] Optionally, first clamping portions 23 are respectively provided on both sides of the end surface of the center air duct seat 20 facing the rear air duct seat 30, and the rear air duct seat 30 is provided with a first clamping structure 32 adapted to the first clamping portion 23, so that the center air duct seat 20 is clamped with the rear air duct seat 30; second clamping portions 24 are respectively provided on both sides of the end surface of the center air duct seat 20 facing the front air duct seat 10, and the front air duct seat 10 is provided with a second clamping structure 13 adapted to the second clamping portion 24, so that the center air duct seat 20 is clamped with the front air duct seat 10.
[0066] By using the embodiment of the present disclosure, the middle air duct seat 20 can be connected to the rear air duct seat 30 by using the first clamping structure 32 and the first clamping part 23, and the middle air duct seat 20 can be connected to the front air duct seat 10 by using the second clamping structure 13 and the second clamping part 24. The clamping method makes the connection between the middle air duct seat 20 and the rear air duct seat 30 and the middle air duct seat 20 and the front air duct seat 10 very convenient. No complicated tools or steps are required. Simply align the clamping part of one component with the clamping structure of another component, and then push it gently to complete the connection. This quick connection method not only saves time, but also reduces the difficulty of installation. At the same time, the clamping method is also easy to maintain and replace. If a certain air duct seat is damaged, it can be easily disassembled and replaced without large-scale disassembly and reinstallation of the entire system. In addition, the snap-on fixing method can ensure that the middle air duct seat 20 and the front air duct seat 10 as well as the middle air duct seat 20 and the rear air duct seat 30 are tightly connected and not easy to loosen, thereby preventing problems such as air leakage and noise caused by loose connection.
[0067] Optionally, a first support rib 2111 is provided on the end surface of the middle air duct seat 20 facing the front air duct seat 10, and the first support rib 2111 is located in the variable temperature return air duct 52; a second support rib is provided on the end surface of the front air duct seat 10 facing the middle air duct seat 20, and the second support rib is arranged corresponding to the first support rib 2111; wherein, when the middle air duct seat 20 is connected to the front air duct seat 10, the first support rib 2111 abuts against the second support rib.
[0068] According to the disclosed embodiment, a first support rib 2111 is provided on the end surface of the middle air duct seat 20 facing the front air duct seat 10, and a second support rib is provided on the end surface of the front air duct seat 10 facing the middle air duct seat 20. When the middle air duct seat 20 is connected to the front air duct seat 10, the first support rib 2111 abuts against the second support rib, forming an additional support point for the middle air duct seat 20 and the front air duct seat 10 when they are connected, which can improve the structural strength of the variable temperature return air duct 52 and avoid the variable temperature return air duct 52 from being compressed and deformed. In addition, the design of the support rib makes the force between the middle air duct seat 20 and the front air duct seat 10 more uniform. This helps to reduce stress concentration and extend the service life of components.
[0069] Combination Figure 3 and Figure 4 As shown in, optionally, the number of the first support ribs 2111 is two, the number of the second support ribs is two, the first support ribs 2111 and the second support ribs are arranged in one-to-one correspondence, and the first support ribs 2111 and the second support ribs are both arranged in the middle of the variable temperature return air duct 52 and extend along the air flow direction.
[0070] In this way, by arranging the first support rib 2111 and the second support rib in the middle of the variable temperature return air duct 52, the air in the variable temperature return air duct 52 can be evenly divided, ensuring the uniformity of the air outflow from the variable temperature return air duct 52. By extending the first support rib 2111 and the second support rib along the air flow direction, the wind noise generated by the first support rib 2111 and the second support rib can be reduced, thereby reducing the noise and improving the user experience.
[0071] Optionally, a third support rib 31 is provided on the end face of the rear air duct seat 30 facing the middle air duct seat 20, and the third support rib 31 is located in the refrigerated return air duct 42; wherein, when the middle air duct seat 20 is connected to the rear air duct seat 30, the third support rib 31 abuts against the end face of the middle air duct seat 20.
[0072] According to the disclosed embodiment, the third support rib 31 is provided on the end surface of the rear air duct seat 30 facing the middle air duct seat 20, and the third support rib 31 is provided in the refrigerated return air duct 42. When the middle air duct seat 20 is connected to the rear air duct seat 30, the third support rib 31 abuts against the middle air duct seat 20. In this way, the structural strength of the refrigerated return air duct 42 can be improved, and the refrigerated return air duct 42 can be prevented from being deformed or damaged due to compression. In addition, the design of the third support rib 31 makes the force between the middle air duct seat 20 and the rear air duct seat 30 more uniform. This helps to reduce stress concentration and extend the service life of the middle air duct seat 20 and the rear air duct seat 30.
[0073] Optionally, a positioning column 22 is provided on the end surface of the middle air duct seat 20 facing the front air duct seat 10, and a positioning groove 12 matched with the positioning column 22 is provided on the end surface of the front air duct seat 10 facing the middle air duct seat 20 to facilitate the installation of the middle air duct seat 20 and the front air duct seat 10.
[0074] By using the embodiment of the present disclosure, by using the positioning column 22 and the positioning groove 12, accurate positioning can be provided during the assembly process, ensuring that the middle air duct seat 20 and the front air duct seat 10 can be accurately aligned, avoiding deviations or misalignments that may occur during the installation process, and ensuring the accuracy of the assembly.
