In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0044] The following is combined with Figures 1 to 5 The refrigeration equipment proposed according to the embodiments of this application can be a wine cabinet, refrigerator, freezer, cabinet, etc. Taking a refrigerator as an example, the refrigeration equipment includes: a cabinet 100, an ice-making chamber 200, an ice-making air duct 300, an air inlet pipe 400, and an air return pipe 500.

[0045] The refrigerator body 100 includes a shell (not shown) and a liner 101. The shell is the outer casing of the refrigerator, and the liner 101 is used for insulation and is located inside the shell. An ice-making chamber 200 is used for ice making and can be installed on the shell or the liner 101. An ice-making duct 300 connects the air inlet duct 400 and the air return duct 500, and an ice-making evaporator 600 is installed in the ice-making duct 300. There is a space between the rear side of the ice-making duct rear cover plate 901 and the liner 101. A foaming cavity is formed between the ice-making duct front cover plate 902 and the ice-making duct rear cover plate 901, and the foaming cavity is filled with foaming material and / or vacuum insulation board. The air inlet duct 400 and the air return duct 500 are snap-fitted to the liner 101, which allows users to easily install and remove the air inlet duct 400 and the air return duct 500.

[0046] In this embodiment, both the air inlet duct 400 and the air return duct 500 are disposed between the inner liner 101 and the outer shell. The air inlet duct 400 is used to supply air to the ice-making chamber 200, and its two ends are connected to the ice-making chamber 200 and the ice-making air duct 300, respectively. The air return duct 500 is used to return air to the ice-making air duct 300, and its two ends are connected to the ice-making chamber 200 and the ice-making air duct 300, respectively. The air inlet duct 400 connects the top of the ice-making chamber 200 and the top of the ice-making air duct 300, and the two ends of the air return duct 500 connect the bottom of the ice-making chamber 200 and the bottom of the ice-making air duct 300.

[0047] During operation, the ice-making chamber 200 in the refrigeration equipment draws in cold air from the upper part of the ice-making evaporator 600, and then sends it into the ice-making chamber 200 through the ice-making air duct 300. After the cold air is cooled by the ice-making chamber 200, its temperature rises, and then it returns to the bottom of the ice-making evaporator 600 through the return air duct 500. It exchanges heat with the ice-making evaporator 600 at the same time. The air cooled by the ice-making evaporator 600 re-enters the ice-making air duct 300 to complete one air supply and return refrigeration cycle.

[0048] like Figure 4 and Figure 5As shown, since the air inlet duct 400 and the return air duct 500 are only connected to the housing liner 101 by a snap-fit ​​connection, to ensure the stability of the air inlet duct 400 and the return air duct 500 during operation, each air inlet duct 400 and the return air duct 500 is connected to a support column 700. The end of the support column 700 away from the air inlet duct 400 or the return air duct 500 abuts against the housing shell. Thus, the support column 700 on the air inlet duct 400 supports the air inlet duct 400 between the air inlet duct 400 and the housing shell, ensuring the stability of the air inlet duct 400. The support column 700 on the return air duct 500 supports the return air duct 500 between the return air duct 500 and the housing shell, ensuring the stability of the return air duct 500. By pressing the support column 700 against the housing shell, the air inlet duct 400 and the return air duct 500 are pressed tightly against the housing liner 101, ensuring the stability of the air inlet duct and the return air duct fixed to the housing liner.

[0049] When assembling the refrigeration equipment, first fix the air inlet pipe 400 to the inner box 101 with a snap-fit. Then, pre-fix the ice-making chamber 200 to the inner box 101 and set up the ice-making air duct 300 and ice-making evaporator 600. Then, fix the return air pipe 500 to the inner box 101 with a snap-fit. Finally, fix the ice-making chamber 200 to the inner box 101 with screws.

[0050] The refrigeration equipment provided by this invention includes an ice-making chamber 200 and an ice-making air duct 300. The ice-making air duct 300 is installed inside a cabinet liner 101, and an ice-making evaporator 600 is installed within it. An inlet air pipe 400 and a return air pipe 500 are connected to the cabinet liner 101 via a snap-fit ​​connection, and are embedded between the cabinet liner 101 and the cabinet shell. The inlet air pipe 400 and the return air pipe 500 connect the ice-making chamber 200. Along with the ice-making air duct 300, support pillars 700 are configured on the inlet duct 400 and return duct 500 to abut against the casing. The casing presses against the support pillars 700, thus pressing the inlet duct 400 and return duct 500 tightly against the casing 101. This simplifies the installation process while ensuring the refrigeration equipment can produce ice normally. The fixing and sealing of the inlet duct 400 and return duct 500 does not require screws or adhesive tape, thereby reducing material usage and improving manufacturability. It also ensures the stability of the inlet duct 400 and return duct 500 fixed to the casing 101.

[0051] The position of the support column 700 on the air inlet duct 400 and the air return duct 500 can be adjusted according to user needs. If only one support column 700 is installed on the air inlet duct 400 and the air return duct 500, the support column 700 is generally installed at the end of one side of the air inlet duct 400 and the air return duct 500.

[0052] According to one embodiment of the present invention, such as Figure 6As shown, the air inlet duct 400 includes a first cover plate 401 and a second cover plate 402 that are interlocked. The first cover plate 401 and the second cover plate 402 also have interlocking structures, meaning that the first cover plate 401 and the second cover plate 402 are respectively provided with a snap-fit ​​and a slot for connection, allowing the first cover plate 401 and the second cover plate 402 to be connected by snap-fit. After the first cover plate 401 and the second cover plate 402 are interlocked, an air inlet channel for air intake into the ice-making chamber 200 is formed between the first cover plate 401 and the second cover plate 402. The two ends of the air inlet channel are connected to the ice-making chamber 200 and the ice-making air duct 300, respectively. By using a snap-fit ​​connection between the liner 101, the first cover plate 401, and the second cover plate 402, the structures such as the liner 101, the first cover plate 401, and the second cover plate 402 can be detachably connected, simplifying the installation process of the air inlet duct 400, thereby saving labor time and reducing costs.

[0053] Specifically, such as Figure 6 As shown, a first latch 4010 is provided on the first cover plate 401, and a first slot 4020 matching the first latch 4010 is provided on the second cover plate 402. For example, the first latch 401 is constructed on the first cover plate 401, and the first slot 4020 matching the first latch 4010 is constructed on the second cover plate 402. The first cover plate 401 is detachably connected to the second cover plate 402 via the first latch 4010 and the first slot 4020. When the first cover plate 401 and the second cover plate 402 are connected, the first latch 4010 can be extended into the first slot 4020, and the first cover plate 401 and the second cover plate 402 are connected using the first latch 4010 and the first slot 4020. When the first cover plate 401 and the second cover plate 402 are disassembled, the first latch 4010 can be removed from the first slot 4020, thereby separating the first cover plate 401 and the second cover plate 402.

[0054] To ensure the sealing effect of the air inlet duct 400 and improve the connection strength of the first cover plate 401 and the second cover plate 402, multiple first buckles 4010s spaced apart from each other can be provided on the first cover plate 401. Correspondingly, first slots 4020 are constructed on the second cover plate 402 to match the first buckles 4010 one by one. When the first cover plate 401 and the second cover plate 402 are connected, the multiple first buckles 4010s can be extended into the corresponding first slots 4020, and the first cover plate 401 and the second cover plate 402 are connected by the multiple first buckles 4010s and the multiple first slots 4020s. When the first cover plate 401 and the second cover plate 402 are disassembled, all the first buckles 4010s can be removed from the corresponding first slots 4020s, thereby separating the first cover plate 401 and the second cover plate 402. By providing multiple first buckles 4010s and multiple first slots 4022s, the sealing effect of the air inlet duct 400 can be effectively improved.

[0055] Correspondingly, such as Figure 7 As shown, the return air duct 500 includes a third cover plate 501 and a fourth cover plate 502 that are interlocked.

[0056] In this embodiment, the third cover plate 501 and the fourth cover plate 502 are also provided with snap-fit ​​connection structures. That is, the third cover plate 501 and the fourth cover plate 502 are respectively provided with snap-fit ​​and slot for connection, so that the third cover plate 501 and the fourth cover plate 502 can be connected by snap-fit ​​connection. After the third cover plate 501 and the fourth cover plate 502 are snap-fit ​​connected, a return air channel for the return air of the ice-making air duct 300 is constructed between the third cover plate 501 and the fourth cover plate 502. The two ends of the return air channel are connected to the ice-making chamber 200 and the ice-making air duct 300, respectively. By using snap-fit ​​connection for the box liner 101, the third cover plate 501 and the fourth cover plate 502, the structures such as the box liner 101, the third cover plate 501 and the fourth cover plate 502 can be detachably connected, simplifying the installation process of the return air duct 500, thereby saving time and reducing costs.

[0057] Specifically, such as Figure 7 As shown, a second latch 5010 is provided on one of the third cover plate 501 and the fourth cover plate 502, and a second slot 5020 that matches the second latch 5010 is provided on the other. For example, the third cover plate 501 has a second latch 5010, and the fourth cover plate 502 has a second slot 5020 that matches the second latch 5010. The third cover plate 501 is detachably connected to the fourth cover plate 502 via the second latch 5010 and the second slot 5020. When the third cover plate 501 and the fourth cover plate 502 are connected, the second latch 5010 can be extended into the second slot 5020, and the third cover plate 501 and the fourth cover plate 502 are connected by the second latch 5010 and the second slot 5020. When disassembling the third cover plate 501 and the fourth cover plate 502, the second buckle 5010 can be removed from the second slot 5020, thereby separating the third cover plate 501 and the fourth cover plate 502.

[0058] To ensure the sealing effect of the return air duct 500 and improve the connection strength between the third cover plate 501 and the fourth cover plate 502, multiple second clips 5010 spaced apart from each other can be provided on the third cover plate 501. Correspondingly, second slots 5020 are constructed on the fourth cover plate 502 to match the second clips 5010 one-to-one. When connecting the third cover plate 501 and the fourth cover plate 502, the multiple second clips 5010 can extend into the corresponding second slots 5020, connecting the third cover plate 501 and the fourth cover plate 502 using the multiple second clips 5010 and the multiple second slots 5020. When disassembling the third cover plate 501 and the fourth cover plate 502, all the second clips 5010 can be removed from the corresponding second slots 5020, thus separating the third cover plate 501 and the fourth cover plate 502. By providing multiple second clips 5010 and multiple second slots 5022, the sealing effect of the return air duct 500 can be effectively improved.

[0059] like Figure 6 and Figure 7 As shown, the first latch 4010 and the second latch 5010 have the same structure, both including a baffle 4011 and a support leg 4012. The first slot 4020 and the second slot 5020 have the same structure, both having a notch 4021. The baffle 4011 of the first latch 4010 is connected to the first cover plate 401 via the corresponding support leg 4012. The baffle 4011 of the second latch 5010 is connected to the third cover plate 501 via the corresponding support leg 4012.

[0060] When the first cover plate 401 and the second cover plate 402 are connected, the baffle 4011 of the first buckle 4010 passes through the notch 4021 of the first slot 4020. When disassembling the first cover plate 401 and the second cover plate 402, the baffle 4011 of the first buckle 4010 can be directly removed from the notch 4021 of the first slot 4020. When the third cover plate 501 and the fourth cover plate 502 are connected, the baffle 4011 of the second buckle 5010 passes through the notch 4021 of the second slot 5020. When disassembling the third cover plate 501 and the fourth cover plate 502, the baffle 4011 of the second buckle 5010 can be directly removed from the notch 4021 of the second slot 5020.

[0061] According to one embodiment of the present invention, such as Figure 6 As shown, the first cover plate 401 and the second cover plate 402 are respectively provided with a first groove 4013 and a second groove 4022 on their adjacent sides, that is, the first cover plate 401 is provided with a first groove 4013 and the second cover plate 402 is provided with a second groove 4022. When the first cover plate 401 and the second cover plate 402 are interlocked, the first groove 4013 and the second groove 4022 interlock to form an air inlet channel.

[0062] To connect the two ends of the air inlet duct to the ice-making chamber 200 and the ice-making air duct 300 respectively, two first air vents can be provided on the first cover plate 401. These two first air vents connect to the top of the ice-making chamber 200 and the top of the ice-making air duct 300 respectively. By providing first air vents only on the first cover plate 401 connected to the inner liner 101, the structure of the air inlet duct 400 can be simplified. Furthermore, depending on user needs, two first air vents for connecting the ice-making chamber 200 and the ice-making air duct 300 can also be provided on the second cover plate 402, or simultaneously on both the first cover plate 401 and the second cover plate 402.

[0063] To ensure the seal at the connection between the first cover plate 401 and the second cover plate 402, a first sealing rib 4000 can be provided in the first groove 4013 of the first cover plate 401, or in the second groove 4022 of the second cover plate 402, or both the first groove 4013 and the second groove 4022 can be provided. The first sealing rib 4000 allows the first cover plate 401 and the second cover plate 402 to be inserted and fitted together. On the other hand, when the first cover plate 401 and the second cover plate 402 are connected, the first sealing rib 4000 forms a first sealing cavity in the air inlet channel. The first sealing cavity is used to seal the connection between the first cover plate 401 and the second cover plate 402.

[0064] like Figure 7 As shown, the third cover plate 501 and the fourth cover plate 502 are respectively provided with a third groove 5013 and a fourth groove 5023 on their adjacent sides, that is, the third cover plate 501 is provided with a third groove 5013 and the fourth cover plate 502 is provided with a fourth groove 5023. When the third cover plate 501 and the fourth cover plate 502 are interlocked, the third groove 5013 and the fourth groove 5023 interlock to form a return air channel.

[0065] To connect the two ends of the return air duct to the ice-making chamber 200 and the ice-making air duct 300 respectively, two second air vents can be provided on the third cover plate 501. These two second air vents connect to the bottom of the ice-making chamber 200 and the bottom of the ice-making air duct 300 respectively. By providing second air vents only on the third cover plate 501 connected to the inner liner 101, the structure of the return air duct 500 can be simplified. Furthermore, depending on user needs, two second air vents for connecting the ice-making chamber 200 and the ice-making air duct 300 can also be provided on the fourth cover plate 502, or simultaneously on both the third and fourth cover plates 501.

[0066] To ensure the seal at the connection between the third cover plate 501 and the fourth cover plate 502, a second sealing rib 5000 can be provided in the third groove 5013 of the third cover plate 501, or in the fourth groove 5023 of the fourth cover plate 502, or simultaneously in both the third groove 5013 and the fourth groove 5023. The second sealing rib 5000 allows the third cover plate 501 and the fourth cover plate 502 to be interlocked, and when the third cover plate 501 and the fourth cover plate 502 are connected, the second sealing rib 5000 forms a second sealing cavity in the return air duct, which is used to seal the connection between the third cover plate 501 and the fourth cover plate 502.

[0067] According to one embodiment of the present invention, such as Figures 1 to 7 As shown, the first cover plate 401 adopts a contoured structure, extending along the outer wall of the liner 101, and is connected to the outer wall of the liner 101 by snap-fit, thereby effectively increasing the reliability of the fixed seal. Specifically, the first cover plate 401 serves as the bottom plate of the air inlet duct, and the second cover plate 402 serves as the top plate of the air inlet duct. Since the air inlet duct 400 is snap-fitted to the liner 101, corresponding snap-fit ​​connection structures can be provided on the first cover plate 401, the second cover plate 402, and the liner 101, that is, as... Figure 4 As shown, the first cover plate 401 and the second cover plate 402 are both provided with a third slot 4014, and the inner box 101 is provided with a third buckle 1010. After the first cover plate 401 and the second cover plate 402 are connected, if the third buckle 1010 extends into the two third slots 4014, the first cover plate 401 and the second cover plate 402 can be connected to the inner box 101.

[0068] Correspondingly, the third cover plate 501 adopts a contoured structure, extending along the outer wall of the inner liner 101, and is connected to the outer wall of the inner liner 101 with snap-fit ​​fasteners, thereby effectively increasing the reliability of the fixed seal. Specifically, the third cover plate 501 serves as the bottom plate of the return air duct, and the fourth cover plate 502 serves as the top plate of the return air duct. Since the return air duct 500 is snap-fit ​​fastened to the inner liner 101, corresponding snap-fit ​​connection structures can be provided on the third cover plate 501, the fourth cover plate 502, and the inner liner 101, that is, as... Figure 5 As shown, the third cover plate 501 and the fourth cover plate 502 are each provided with a fourth slot 5014, and the inner box 101 is provided with a fourth buckle 1011. After the third cover plate 501 and the fourth cover plate 502 are connected, if the fourth buckle 1011 extends into the two fourth slots 5014, the third cover plate 501 and the fourth cover plate 502 can be connected to the inner box 101.

[0069] In addition, to ensure the stability of the air inlet duct 400 and the return air duct 500, the outer wall of the casing 101 is generally provided with two third clips 1010 corresponding to the air inlet duct 400 and two fourth clips 1011 corresponding to the return air duct 500. At the same time, both ends of the first cover plate 401 and the second cover plate 402 are provided with two third slots 4014, and both ends of the third cover plate 501 and the fourth cover plate 502 are provided with two fourth slots 5014. During installation, multiple clips are inserted into the corresponding slots to completely fix the air inlet duct 400 and the return air duct 500 to the casing 101.

[0070] In this embodiment, the outer wall of the box liner 101 is provided with a third sealing rib. The third sealing rib is disposed on the outer wall of the box liner 101 and extends along the edge of the first cover plate 401 or the third cover plate 501, or extends along the edges of both the first cover plate 401 and the third cover plate 501. The position of the third sealing rib is set as needed. For example, the third sealing rib may extend along one edge of the first cover plate 401 or along the entire circumferential edge of the first cover plate 401 to achieve sealing at different positions on the first cover plate 401.

[0071] Based on the height and position of the third sealing rib, the third sealing rib can be used to hold the first cover plate 401 and / or the third cover plate 501 in place. The third sealing rib can also be used to seal between the first cover plate 401 and the inner chamber 101, as well as between the third cover plate 501 and the inner chamber 101, to prevent the foaming liquid from entering the air inlet pipe 400 or the air return pipe 500 during foaming.

[0072] Based on the above embodiments, according to an embodiment provided by the present invention, such as Figures 1 to 7 As shown, when it is necessary to further compress the air inlet pipe 400 and the return air pipe 500, the air inlet pipe 400 and the return air pipe 500 can be pressed against the box liner 101 by pressing multiple support columns 700 with the box shell. Thus, multiple support columns 700 arranged at intervals can be connected to both the air inlet pipe 400 and the return air pipe 500, fixing the air inlet pipe 400 and the return air pipe 500 between the box shell and the box liner 101.

[0073] The air inlet duct 400 includes a first cover plate 401 and a second cover plate 402 that are interlocked. The first cover plate 401 is fastened to the inner casing 101, and the second cover plate 402 is fastened to the first cover plate 401. If the support column 700 is installed on the first cover plate 401, the support column 700 can press the first cover plate 401 tightly. If the support column 700 is installed on the second cover plate 402, the support column 700 can simultaneously press the first cover plate 401 and the second cover plate 402, thereby providing a pressing force to the air inlet duct 400 and pressing the cover plates and the inner casing 101 tightly.

[0074] The return air duct 500 includes a third cover plate 501 and a fourth cover plate 502 that are interlocked. The third cover plate 501 is fastened to the inner casing 101, and the fourth cover plate 502 is fastened to the third cover plate 501. If the support column 700 is installed on the third cover plate 501, the support column 700 can press the third cover plate 501 tightly. If the support column 700 is installed on the fourth cover plate 502, the support column 700 can simultaneously press both the third cover plate 501 and the fourth cover plate 502, thereby providing a clamping force to the return air duct 500 and pressing the cover plates and the inner casing 101 tightly.

[0075] Based on the above embodiments, according to an embodiment provided by the present invention, such as Figures 1 to 7 As shown, a foam layer is filled between the shell and the inner liner 101. The foam layer includes foam material and / or vacuum insulation board. The air inlet duct 400 and the return air duct 500 are embedded in the foam layer, and the support column 700 passes through the foam layer. The air inlet duct 400 and the return air duct 500 are pressed tightly against the inner liner 101 by the shell pressing the support column 700. This achieves the fixation and sealing of the air inlet duct 400 and the return air duct 500 without the need for screws or adhesive tape, thereby reducing material usage, improving product manufacturability, and reducing costs.

[0076] In this embodiment, during the assembly of the refrigeration equipment, the air inlet pipe 400 is first fixed to the liner 101 by means of a snap-fit. Then, the ice-making chamber 200 is pre-fixed to the liner 101, and the ice-making air duct 300 and the ice-making evaporator 600 are installed. The return air pipe 500 is then fixed to the liner 101 by means of a snap-fit. The ice-making chamber 200 is fixed to the liner 101 by screws. Then, foaming material is filled into the foaming cavity between the air inlet pipe 400 and the liner 101. The foaming material solidifies in the foaming cavity to form a foam layer, thereby embedding the air inlet pipe 400 and the return air pipe 500 in the foam layer, and the support column 700 is inserted into the foam layer.

[0077] Based on the above embodiments, according to an embodiment provided by the present invention, such as Figures 1 to 3 As shown, a fan 800 is installed in the ice-making duct 300, which drives the air to circulate between the ice-making duct 300 and the ice-making chamber 200. During operation, the ice-making chamber 200 draws in cold air from the top of the ice-making evaporator 600 via the fan 800, and then sends it into the ice-making chamber 200 through the ice-making duct 300. After being cooled by the ice-making chamber 200, the temperature of the cold air rises, and it returns to the bottom of the ice-making evaporator 600 through the return air duct 500. The air then exchanges heat with the ice-making evaporator 600, and the cooled air re-enters the ice-making duct 300 to complete one cycle of air supply and return.

[0078] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
