The refrigerator 100 may also include a press chamber 16 disposed at the bottom of the housing 1. The press chamber 16 may be provided with a compressor, a condenser, and the like.

[0037] In this embodiment, a storage compartment 13 is formed inside the inner container 12. The storage compartment 13 can be a freezer compartment, a temperature-changing room, a refrigerator compartment, etc. The refrigerator 100 is provided with a direct cooling or air cooling structure for supplying cold to the storage compartment 13.

[0038] In this embodiment, the width direction of the refrigerator 100 is the left-right direction, the depth direction of the refrigerator 100 is the front-back direction, and the height direction of the refrigerator 100 is the up-down direction, wherein the opening direction of the storage compartment 13 is the front.

[0039] In this embodiment, an ice making chamber 14 is provided in the storage compartment 13 .

[0040] In one embodiment, the refrigeration device may include a partition 15 disposed in the storage compartment 13, wherein the partition 15 and the side wall of the storage compartment 13 enclose an ice making chamber 14. The partition 15 may be a heat-insulating partition.

[0041] In one embodiment, the ice making chamber 14 is located on the top of the storage compartment 13. After the box body 1 is foamed, a partition 15 can be installed inside the box body 1 to separate the ice making chamber 14.

[0042] In this embodiment, the ice-making chamber 14 can be a space enclosed by the inner tank 12 and the partition 15. Other partitions can be installed in the ice-making chamber 14 to separate the ice-making chamber 14, such as partitions can be installed in the ice-making chamber 14 to separate the air duct or a chamber for installing components such as an evaporator.

[0043] In this embodiment, the refrigerator 100 further includes an ice maker 17 disposed in the ice making chamber 14. The refrigerator 100 may further include an ice storage box disposed in the ice making chamber 14. The ice storage box may be disposed below the ice maker 17.

[0044] 3 , in this embodiment, the refrigerator 100 further includes a refrigeration system 200 disposed in the ice-making chamber 14 . The refrigeration system 200 is configured to provide cooling to the ice-making chamber 14 . The refrigeration system 200 includes an evaporator 210 .

[0045] In this embodiment, additional evaporators may be installed within the housing 1 to provide cooling to the storage compartment 13, such as by installing an evaporator at the rear or bottom of the storage compartment 13. The housing 1 may also include additional inner containers to form additional storage compartments. For example, in addition to the inner container 12, the housing 1 may also include a refrigeration container to form a refrigerator compartment and a freezer container to form a freezer compartment. The refrigerator 100 may provide cooling to other storage compartments using additional evaporators. For example, the housing 1 may include a refrigeration evaporator to provide cooling to the refrigerator compartment and a freezer evaporator to provide cooling to the freezer compartment. The refrigerator 100 may also provide cooling to other storage compartments using the evaporator that provides cooling to the storage compartment 13. For example, the evaporator that provides cooling to the storage compartment 13 may also provide cooling to other storage compartments. The evaporators within the refrigerator 100 may share a single compressor.

[0046] With such an arrangement, a closed and independent ice-making chamber 14 can be provided in the storage compartment 13. By arranging a refrigeration system 200 specifically for cooling the ice-making chamber 14 in the ice-making chamber 14, odors or bacteria in the storage compartment 13 can be prevented from entering the ice-making chamber 14, thereby ensuring the cleanliness of the ice-making chamber 14 and enabling the ice-making chamber 14 to prepare clean ice.

[0047] 3 to 17 , which are diagrams of a refrigeration device according to a first embodiment of the present application, the refrigeration device according to the first embodiment will be described in detail below.

[0048] In this embodiment, the storage compartment 13 is a freezing compartment or a temperature-changing compartment, that is, the ice-making compartment 14 is arranged in the freezing compartment or the temperature-changing compartment.

[0049] 1, 3, and 4, in an embodiment of the present application, a refrigeration system 200 may include a housing 290. An evaporator 210 may be installed within the space formed by the housing 290. In one embodiment, an insulation layer 280 is provided between the evaporation chamber 208 and the ice making chamber 14. The insulation layer 280 is disposed inside the housing 290 and within the evaporation chamber 208.

[0050] In this embodiment, the refrigeration system 200 may further include a fan assembly. The fan assembly may be pre-installed in the housing 290. The fan assembly may include a fan bracket 240, a fan housing 230, and a fan 220. The fan 220 may be disposed within the fan housing 230, and the fan housing 230 may be mounted on the fan bracket 240.

[0051] In this embodiment, the refrigeration system 200 may further include a drainage assembly. The drainage assembly may be mounted on the housing 290. The drainage assembly may include a water receiving tray 250, a heating element 270, and the like.

[0052] In this embodiment, the fan assembly and the drainage assembly can be pre-installed in the housing 290 , and the fan assembly, the drainage assembly and the housing 290 form a housing integrated module 300 .

[0053] During the installation and manufacturing process, the evaporator 210 in the refrigeration system 200 can be directly installed in the ice making chamber 14, and then the housing integrated module 300 in the refrigeration system 200 can be installed in the ice making chamber 14. Of course, in other embodiments, the housing integrated module 300 can also include the evaporator 210.

[0054] In this embodiment, the housing 290 and the wall of the ice-making chamber 14 can form a relatively enclosed evaporation chamber 208, and the evaporator 210 and the fan assembly can be disposed within the evaporation chamber 208. The housing 290 can be provided with an air outlet 291 and an air return port 292, which connect the evaporation chamber 208 and the ice-making chamber 14. When the fan 220 is in operation, the cold air in the evaporation chamber 208 enters the ice-making chamber 14 through the air outlet 291, thereby lowering the temperature of the ice-making chamber 14. The air in the ice-making chamber 14 enters the evaporation chamber 208 through the air return port 292 and exchanges heat with the evaporator 210.

[0055] In this embodiment, the refrigeration system 200 can be arranged at the top, rear, bottom, etc. of the ice making chamber 14. The ice maker 17 can be arranged above and below the refrigeration system 200, arranged side by side, or arranged front and back. The refrigeration system 200 can be located above the ice storage box.

[0056] As shown in Figures 1 and 3, in one embodiment provided by the present application, the ice maker 17 and the refrigeration system 200 can both be installed on the top of the ice making chamber 14. The ice maker 17 and the refrigeration system 200 are arranged side by side along the width direction of the box body 1.

[0057] A return air vent 292 is formed at the front end of the housing 290, and an air outlet 291 is formed at the rear end of the refrigeration system 200, near the ice maker 17. Both the air outlet 291 and the return air vent 292 are located above the ice storage bin. The air outlet 291 can be located behind the ice maker 17. When the fan 220 is activated, cold air within the evaporation chamber 208 flows from the rear air outlet 291 toward the ice maker 17, flowing from back to front. After passing through the ice maker 17 from back to front, the cold air flows from the ice maker 17 side of the ice making compartment 14 to the refrigeration system 200 side. On the ice making compartment 14 side of the refrigeration system 200, the cold air flows from front to back and enters the evaporation chamber 208 through the front air outlet 292. This allows the refrigeration system 200 to blow cold air from the rear toward the ice maker 17 and draw air from the front, effectively cooling the ice maker 17.

[0058] In this embodiment, the evaporator 210 may be disposed at the front of the evaporation chamber 208. The return air port 292 is disposed at the front end of the evaporation chamber 208. The front end of the evaporator 210 may be opposite to the return air port 292.

[0059] The fan 220 can be disposed at the rear of the evaporation chamber 208. An air outlet 291 is disposed at the rear end of the evaporation chamber 208. The air outlet 291 is located on the side of the fan 220 that is closest to the ice maker 17. In one embodiment, the air outlet 291 is disposed at the rear of the ice maker. The air outlet 291 can be opposite the ice maker 17.

[0060] An air duct may be formed between the fan 220 and the air outlet 291. The air duct between the fan 220 and the air outlet 291 may be configured to have a certain slope, for example, the air duct may gradually slope downward from the fan 220 to the air outlet 291. This configuration can prevent defrosting heat from concentrating during defrosting by the fan 220 or the evaporator 210, thereby reducing the impact of the defrosting heat on the ice in the ice storage bin.

[0061] The evaporator 210 is located in front of the fan 220. After entering the evaporation chamber 208 from the return air port 292, the air in the ice-making chamber 14 flows from front to back within the evaporation chamber 208. It first flows through the evaporator 210 at the front and fully exchanges heat with the evaporator 210 before flowing to the fan 220 at the rear. Under the action of the fan 220, the air flows from the air outlet 291 at the rear to the ice-making chamber 14.

[0062] In this embodiment, the refrigeration system 200 and the ice maker 17 may be installed first, and then the partition 15 may be installed to form the ice making chamber 14 .

[0063] 1 , 5 , and 6 , in one embodiment of the present application, refrigerator 100 further includes an embedded rack 2. Embedded rack 2 includes an embedded portion 20 and a connecting portion 21. Embedded portion 20 is positioned within the foaming space, and connecting portion 21 is positioned within ice-making chamber 14. In this embodiment, refrigeration system 200 may be connected to connecting portion 21 of embedded rack 2.

[0064] The ice maker 17 is also connected to the connection portion 21 of the embedded frame 2 .

[0065] 1 to 6 , in this embodiment, a method for installing a refrigerator 100 is also provided. The method includes:

[0066] Fixing the box shell 11 of the refrigerator 100 to the box shell mold;

[0067] The inner container 12 of the refrigerator 100 is fixed to the inner container mold, and the embedded frame 2 is set on the top of the outer wall of the inner container 12. The embedded frame 2 includes a connecting portion 21, which passes through the wall of the inner container 12 and is placed inside the inner container 12. The inner container mold and the box shell mold are arranged opposite to each other;

[0068] Combine the box shell mold and the liner mold;

[0069] Fill the foaming space between the box shell 11 and the inner liner 12 with foam insulation material;

[0070] Separate the refrigerator 100 from the shell mold and the liner mold;

[0071] The refrigeration system 200 of the refrigerator 100 is placed in the ice-making chamber 14 , which is located on the top of the storage compartment 13 formed by the inner tank 12 , and the refrigeration system 200 is connected to the connection portion 21 of the embedded frame 2 .

[0072] Since the evaporator 210 and other components in the refrigeration system 200 are relatively heavy, by connecting the refrigeration system 200 in the ice-making chamber 14 to the embedded frame 2, the fixing strength of the refrigeration system 200 in the ice-making chamber 14 can be ensured, the refrigeration system 200 in the ice-making chamber 14 can be firmly fixed, and the centralized modular setting and installation of the various components in the refrigeration system 200 can be facilitated.

[0073] 3 and 5 , in this embodiment, the housing 290 and the top wall of the ice making chamber 14 are connected to form the evaporation chamber 208. The housing 290 can be connected to the connecting portion 21 of the embedded frame 2.

[0074] Referring to Figures 6 and 7 , in this embodiment, the embedded portion 20 of the embedded frame 2 may include a main plate 22. The main plate 22 covers at least the entire top wall of the inner liner 12 between the front and rear ends of the housing 290. The main plate 22 may also completely cover the top wall of the inner liner 12. This arrangement prevents deformation of the top wall of the inner liner 12 caused by uneven heating of the top of the inner liner 12 when the foaming space is filled with foam insulation material.

[0075] Referring to Figures 6 and 7, in this embodiment, the embedded portion 20 of the embedded frame 2 may further include a positioning plate 23. The positioning plate 23 is connected to at least one of the left wall, right wall, and rear wall of the inner liner 12. In one embodiment, the positioning plate 23 includes a left positioning plate covering the top of the left wall of the inner liner 12, a right positioning plate covering the top of the right wall of the inner liner 12, and a rear positioning plate covering the top of the rear wall of the inner liner 12. In other embodiments of the present patent, the positioning plate 23 may include any one or two of the left positioning plate, the right positioning plate, and the rear positioning plate. By setting the positioning plate 23 in contact with the side wall of the inner liner 12, the accuracy of the installation position of the embedded frame 2 can be guaranteed.

[0076] In this embodiment, the main board 22 and positioning plate 23 are integrally formed. In other embodiments of this patent, the main board 22 and positioning plate 23 may also be provided separately. The arrangement of the main board 22 and positioning plate 23 of the embedded frame 2 ensures that the top wall of the liner 12 and the shell 290 fit together properly, avoiding gaps at the junction of the shell 290 and the top wall of the liner 12, ensuring the sealing of the evaporation chamber 208 and preventing localized frost.

[0077] 2, 6, and 7, in this embodiment, the embedded portion 20 of the embedded frame 2 includes a receiving groove 24. The receiving groove 24 has an opening toward the ice-making chamber 14. The refrigerator 100 also includes a refrigerant pipe 18. The refrigerant pipe 18 passes from the compressor chamber 16 into the foaming space, and then from the foaming space into the receiving groove 24 to connect to the evaporator 210. The portion of the refrigerant pipe 18 within the compressor chamber 16 can be connected to the compressor and condenser.

[0078] In one embodiment, a clip 25 for securing the refrigerant tube 18 may be provided within the receiving groove 24. Before the evaporator 210 is installed in the inner liner 12, the refrigerant tube 18 may be placed within the receiving groove 24 and secured with the clip 25 within the receiving groove 24 to prevent the refrigerant tube 18 from extending into the inner liner 12. When the evaporator 210 is installed in the inner liner 12, the refrigerant tube 18 may be disengaged from the clip 25 and allowed to extend through the opening of the receiving groove 24 into the ice-making chamber 14 and connect to the evaporator 210.

[0079] 1 to 7 , in this embodiment, the installation method of the refrigerator 100 includes:

[0080] The embedded frame 2 is set in the inner container 12 of the refrigerator 100. The embedded frame 2 includes an embedded portion 20 placed outside the inner container 12. The embedded portion 20 of the embedded frame 2 includes a receiving groove 24. The receiving groove 24 has an opening to the ice making chamber 14 inside the inner container 12.

[0081] Insert the refrigerant pipe 18 of the refrigerator 100 from the corresponding position of the compressor chamber 16 at the bottom of the refrigerator 100 through the outside of the inner tank 12 into the receiving groove 24;

[0082] Fix the inner liner 12 to the inner liner mold;

[0083] Fix the box shell 11 of the refrigerator 100 to the box shell mold, with the liner mold and the box shell mold facing each other;

[0084] Combine the box shell mold and the liner mold;

[0085] Fill the foaming space between the box shell 11 and the inner liner 12 with foam insulation material;

[0086] Separate the refrigerator 100 from the shell mold and the liner mold;

[0087] The evaporator 210 is installed in the ice making chamber 14 of the storage compartment 13 of the inner tank 12;

[0088] The refrigerant pipe 18 and the evaporator 210 are connected.

[0089] Since the inner liner mold needs to be inserted into the inner liner 12 and fit the inner wall of the inner liner 12 during foaming of the box body 1 to prevent deformation of the inner liner 12, the refrigerant tube 18 is easily damaged when it is suspended in the ice making chamber 14. The design of this patent can protect the refrigerant tube 18 and effectively prevent the refrigerant tube 18 from interfering with the inner liner mold during foaming of the box body 1, thereby preventing damage to the refrigerant tube 18. The inner liner mold also does not need to have a refrigerant tube 18 avoidance structure, which makes the structure simpler and can better ensure the fit between the foaming mold and the inner liner 12, thus preventing the inner liner 12 from foaming and deformation.

[0090] In this embodiment, a connecting structure is provided between the evaporator 210 and the embedded frame 2, and a connecting structure is also provided between the shell 290 and the embedded frame 2. The evaporator 210 can be installed to the embedded frame 2 first, and then the shell 290 can be installed to the embedded frame 2.

[0091] Referring to Figures 3 to 6 , in this embodiment, the evaporator 210 is connected to the connection portion 21 of the embedded frame 2.

The evaporator 210 is connected to the connection portion 21 through the cooperation of the positioning structure 213 with the positioning structure 26, and the cooperation of the snap-fit ​​structure 214 with the snap-fit ​​structure 27.

[0092] In one embodiment, the first end 211 is the front end of the evaporator 210 , and the second end 212 is the rear end of the evaporator 210 . The front end of the evaporator 210 is further provided with a connecting structure 215 , which is connected to the embedded portion 20 through a connecting piece.

[0093] 3 to 6 , in this embodiment, the installation method of the refrigerator 100 further includes:

[0094] The snap-fit ​​structure 214 is snapped onto the snap-fit ​​structure 27 , which is disposed at the rear end of the evaporator 210 , and the snap-fit ​​structure 27 is disposed at the connection portion 21 ; then, the positioning structure 213 is connected to the positioning matching structure 26 , which is disposed at the front end of the evaporator 210 , and the positioning matching structure 26 is disposed at the connection portion 21 .

[0095] 3 to 6 , in this embodiment, the installation method of the refrigerator 100 further includes:

[0096] After the positioning structure 213 is connected to the positioning matching structure 26 , the connection structure 215 at the front end of the evaporator 210 is connected to the embedded portion 20 through a connector.

[0097] In this embodiment, the evaporator 210 includes a first connecting member 216, a second connecting member 217 and an evaporator coil 218. The first connecting member 216 and the second connecting member 217 are symmetrically arranged at the left and right ends of the evaporator coil 218.

At the same time, the upper end of the support portion 271 of the hook 27 is also connected to the bottom surface of the rear fixing plate 2163 located at the rear side of the slot 214 to increase the contact area between the hook 27 and the rear fixing plate 2163, thereby achieving more stable support for the evaporator 210.

[0102] In this embodiment, the first connecting member 216 and the second connecting member 217 may both be made of aluminum plates.

[0103] To install the evaporator 210, place it within the ice making chamber 14, close to the top wall of the inner container 12. Tilt the evaporator 210 forward and backward at a predetermined angle, so that the rear end of the evaporator 210 is higher than the front end. After moving the evaporator 210 backward a certain distance, gently rock it left and right to allow the boss 273 of the hook to enter the slot 214. When the hook 27 engages the slot 214, the evaporator 210 is positioned firmly within the depth of the ice making chamber 1. Move the front end of the evaporator 210 upward and rock it left and right to align the locating post 26 with the connecting hole 215, inserting the locating post into the connecting hole 215. Now that the evaporator 210 is firmly positioned, tighten the fixing screws through the connecting hole 215 of the front fixing plate 2162 into the main plate 22 of the embedded frame 2, thereby attaching the evaporator 210 to the embedded frame 2. Such an arrangement enables the evaporator 210 to be conveniently positioned and installed on the top of the inner container 12 .

[0104] 3, 4, and 8, in one embodiment of the present application, a refrigeration system 200 includes a fan 220 and a fan housing 230. The fan 220 is disposed within the fan housing 230. The fan housing 230 is tilted relative to the horizontal. Accordingly, the fan 220 is also tilted relative to the horizontal. A drain outlet 231 is formed at the lower end of the fan housing 230.

[0105] In this embodiment, the fan 220 can be first installed in the fan housing 230, and then the fan housing 230 can be pre-installed in the housing 290. The fan 220, the fan housing 230 and the housing 290 form a housing integrated module 300. The evaporator 210 can be first installed in the ice making chamber 14, and then the housing integrated module 300 can be installed.

[0106] 3, 4, and 9, in this embodiment, the refrigeration system 200 further includes a water tray 250 with an open top. The housing integrated module 300 may include the water tray 250, which may be pre-installed within the housing 290 to form the housing integrated module 300. The fan housing 230 may be located above the water tray 250. By arranging the fan 220 and the fan housing 230 at an angle, the flow and collection of water above the fan 220 and the fan housing 230 can be facilitated, ensuring the drainage of water from the fan 220 in the refrigeration system 200 and preventing water accumulation in the fan 220 and the fan housing 230.

[0107] 3 and 10 , in this embodiment, the refrigeration system 200 further includes a fan bracket 240. The housing integrated module 300 may include the fan bracket 240, which may be pre-installed within the housing 290 to form the housing integrated module 300. The fan bracket 240 may be located above the water tray 250. The fan bracket 240 includes a support plate 241. The support plate 241 is disposed above the water tray 250 and is inclined relative to the horizontal. The fan housing 230 is fixed to the support plate 241, and a drain outlet 245 is formed at the lower end of the support plate 241.

[0108] In one embodiment, the inclination angle of the fan 220, the fan housing 230, and the support plate 241 relative to the horizontal direction is greater than or equal to 2.5 degrees. For example, the inclination angle of the support plate 241 relative to the horizontal direction may be 5 degrees.

[0109] 3 and 11 , in this embodiment, the refrigeration system 200 includes a heating element 270. The housing integrated module 300 may include a heating element 270, which may be pre-installed in the housing 290 to form the housing integrated module 300. The heating element 270 may be spaced apart from the fan 220. The fan bracket 240 is made of a heat-conducting material and is used to transfer the heat of the heating element 270 to the fan 220. Since the heating element 270 can provide less heat to the fan 220 when the fan 220 is far away from the heating element 270, it is difficult for the fan 220 to defrost. However, by transferring the heat of the heating element 270 to the fan 220 through the fan bracket 240, the defrosting of the fan 220 can be ensured, the defrosting of the fan 220 can be made more thorough, and the life of the fan 220 can be guaranteed.

[0110] 3 and 11 , in this embodiment, the refrigeration system 200 further includes a heat-conducting shield 260. The housing integrated module 300 may include the heat-conducting shield 260, which may be pre-installed within the housing 290 to form the housing integrated module 300. The heat-conducting shield 260 may cover the heater 270. The heat-conducting shield 260 is disposed between the fan bracket 240 and the heater 270. Both the heater 270 and the fan bracket 240 are connected to the heat-conducting shield 260.

[0111] 3 and 11 , in this embodiment, the heater 270 is secured to the heat-conducting shield 260. The bottom wall of the heat-conducting shield 260 may be provided with a plurality of securing members 262 for securing the heater 270. The heat-conducting shield 260 is secured to the water tray 250. The side walls of the water tray 250 may be provided with a plurality of securing members for securing the heat-conducting shield 260.

[0112] In one embodiment, the heat-conducting shield 260 is an aluminum plate. The heat-conducting shield 260 may be formed with drain openings 261. The drain openings 261 of the heat-conducting shield 260 may be arranged in an array along the length and width of the heat-conducting shield 260. Preferably, the length and width of the drain openings 261 are both between 3 and 45 mm. For example, the drain openings 261 are 12 mm long and 6 mm wide. If the drain openings 261 are too large, air returning from the ice-making chamber 14 may pass through the drain openings 261 and flow directly from the space between the heat-conducting shield 260 and the water tray 250 to the fan 220 without passing through the evaporator 210, thus reducing cooling efficiency. On the other hand, if the drain openings 261 are too small, drainage effectiveness will be compromised. The design solution provided in this embodiment features appropriately sized drain openings 261, preventing air from passing through the space between the heat-conducting shield 260 and the water tray 250 and flowing directly to the fan 220. This ensures effective drainage while maintaining cooling efficiency.

[0113] In this embodiment, the heating element 270 may be an aluminum tube heating wire, and the heating wire may extend in an S-shape along the heat conductive shield 260 .

[0114] 3 and 11 , in this embodiment, the heat-conducting shield 260 is disposed between the heating element 270 and the evaporator 210 . The evaporator 210 may be disposed above the water receiving tray 250 .

[0115] In this embodiment, the heater 270 is located above the water tray 250. A heat-conducting shield 260 is located above the heater 270. The support plate 241 of the fan bracket 240 is located above the heat-conducting shield 260 and the heater 270. The fan housing 230 is mounted on the support plate 241 of the fan bracket 240. The lower end of the fan bracket 240 is connected to the heat-conducting shield 260. The heat-conducting shield 260 covers the lower end of the fan bracket 240.

[0116] Such an arrangement can ensure the defrosting efficiency of the heating element 270 and protect the heating element 270, thereby preventing the heating element 270 from being scratched or damaged.

[0117] 3 and 10 , in this embodiment, fan bracket 240 further includes ribs 242 extending downward from support plate 241 to connect with heat-conducting shield 260. Ribs 242 are provided at their lower ends with protruding edges 243 extending along heat-conducting shield 260. Ribs 242 of fan bracket 240 serve to guide water, and the protruding edges 243 at the ends of ribs 242 increase the contact area between fan bracket 240 and heat-conducting shield 260.

[0118] Referring to Figure 3 , in this embodiment, the evaporator 210 is positioned above a heat-conducting shield 260 and a heater 270. The evaporator 210 can be positioned horizontally. The heat-conducting shield 260 covers the underside of the evaporator 210. The evaporator 210 includes an evaporator coil 218 and heat-conducting fins 219 connected to the evaporator coil 218. The lower ends of the heat-conducting fins 219 are connected to the heat-conducting shield 260.

[0119] In this embodiment, to reduce the space occupied by the refrigeration system 200 in the ice-making compartment 14, the fan 220 is placed in close proximity to the evaporator 210, making it susceptible to frost. When the heating wire is activated, heat from the heating wire is transferred to the heat-conducting shield 260. The heat-conducting shield 260 quickly transfers the heat to the fan 220 via the fan bracket 240 and then to the evaporator 210 via the heat-conducting fins 219, enabling rapid defrosting of the fan 220 and evaporator 210. Defrosted water from the fan 220 and evaporator 210 flows downward into the water tray 250, preventing water from freezing in the fan 220 and evaporator 210.

[0120] 1 , 3 and 8 to 11 , in one embodiment, the water receiving tray 250 , the heating element 270 and the heat conductive shield 260 are disposed at the bottom of the evaporation chamber 208 , and the fan 220 is disposed at the top of the evaporation chamber 208 .

[0121] In this embodiment, the fan bracket 240 is located behind the evaporator 210, and the support plate 241 may be formed with an air vent 244 opposite to the fan 220. The fan housing 230 is formed with an opening 232 that cooperates with the air outlet 291 and the air vent of the support plate 241. The plate rib 242 may be formed with an air vent 246.

[0122] Air entering the evaporation chamber 208 from the ice-making chamber 14 first flows through the evaporator 210 at the front end, exchanges heat with the evaporator 210, then passes through the air vents 246 of the plate rib 242, the air vents 244 of the support plate 241, and the opening 232 of the fan housing 230, entering the fan housing 230. Under the action of the fan 220, it flows from the air outlet 291 at the rear end to the ice-making chamber 14, and the cycle continues. In this way, the refrigeration system 200 can blow cold air from the rear side to the ice-making machine 17 and draw air from the front side, thereby improving refrigeration efficiency and fully cooling the ice-making machine 17.

[0123] Referring to Figure 10 , in this embodiment, fan 220 is arranged horizontally. Fan housing 230 is tilted from front to back. A drain port 231 is formed at the rear end of fan housing 230. A drain port 245 is formed at the rear end of support plate 241. Fan support 240 includes a plurality of ribs 242 arranged in parallel and spaced apart. Each rib 242 of fan support 240 extends in the front-to-back direction and is formed with a plurality of air vents 246 to facilitate the flow of air from the front end of evaporation chamber 208 to fan 220.

[0124] Referring to Figures 1 to 5, 7, 9, 12, and 13, in this embodiment, a drain pan 250 is provided with a drain portion 251, the refrigerator 100 further includes a drain pipe 3, and the embedded frame 2 is formed with a drainage channel 28 disposed within the foam layer. The drain portion 251 of the drain pan 250 extends into the drainage channel 28, and the drain pipe 3 is connected to the bottom opening of the drainage channel 28. The drain pipe 3 bends from the bottom opening of the drainage channel 28 and passes through the foam layer at the corner between the left and rear walls or the corner between the right and rear walls of the inner container 12. This arrangement facilitates drainage of the drain pan 250, prevents water leakage, and effectively prevents freezing of the drainage channel 28 and the drain pipe 3.

[0125] In this embodiment, refrigerator 100 further includes an evaporating dish disposed within compressor compartment 16. The upper end of the evaporating dish is open, and a drain pipe 3 passes through the foam layer at the corner between the left and rear walls, or the corner between the right and rear walls, of the inner container 12 and enters compressor compartment 16. The drain pipe 3 bends at the top of compressor compartment 16 and extends into the evaporating dish. Defrosted water from fan 220 and evaporator 210 flows into the evaporating dish and evaporates naturally within the dish.

[0126] Since the drain pipe 3 connects the ice-making chamber 14 with the outside air, there is a pressure difference between the ice-making chamber 14 and the outside air, so the outside air will be sucked back into the ice-making chamber 14. Therefore, by bending the drain pipe 3 at the top of the compressor chamber 16 and extending it into the evaporating dish, the backflow of the outside air into the ice-making chamber 14 can be slowed down.

[0127] In this embodiment, the end of the water receiving tray 250 is provided with a drainage portion 251 extending toward the wall of the inner container 12. The drainage portion 251 of the water receiving tray 250 can be provided at the left or right end of the water receiving tray 250 and close to the rear end of the water receiving tray 250. The drainage channel 28 is placed in the foam layer on the left or right side of the inner container 12 and opposite to the drainage portion 251.

[0128] In this embodiment, the drainage channel 28 includes a first drainage channel 2801 and a second drainage channel 2802 connected to each other. The first drainage channel 2801 extends from the wall of the inner tank 12 toward the box shell 11. The drainage portion 251 extends into the first drainage channel 2801 from the opening of the first drainage channel 2801 near the end of the inner tank 12. The second drainage channel 2802 extends downward from the end of the first drainage channel 2801 near the box shell 11. The drain pipe 3 is connected to the bottom opening of the second drainage channel 2802.

[0129] In this embodiment, the drain portion 251 and the first drain channel 2801 are both downwardly inclined. An opening is formed at the end of the drain portion 251. The bottom wall of the first drain channel 2801 includes a first slope 2803 and a second slope 2804 connected to each other. The first slope 2803 extends from the corner of the first and second drain channels 2801, 2802 to below the end opening of the drain portion 251 in the water receiving tray 250. The second slope 2804 extends from the first slope 2803 to the opening of the first drain channel 2801 near the inner container 12. The inclination angle of the first slope 2803 is greater than the inclination angle of the second slope 2804, which is also greater than the inclination angle of the drain portion 251 in the water receiving tray 250. In one embodiment, the inclination angle of the drain portion 251 is greater than or equal to 2 degrees, the angle of the first slope 2803 is greater than or equal to 3 degrees, and the angle of the second slope 2804 is greater than or equal to 20 degrees. This arrangement can prevent the water in the drainage channel 28 from flowing back and thus prevent water leakage.

[0130] In this embodiment, a gap is formed between the walls of the first drainage channel 2801 and the walls of the drainage portion 251. The cross-sectional dimensions of the first drainage channel 2801 gradually increase from the end closest to the housing 11 to the end closest to the inner container 12. In one embodiment, the cross-sectional dimensions of the first drainage channel 2801 are trapezoidal. This arrangement facilitates the insertion of the drainage portion 251 into the drainage channel 28.

[0131] In this embodiment, refrigerator 100 further includes a heating wire disposed in drain channel 28 and drain pipe 3. The heating wire extends from drain channel 28 to at least the corner of the left and right walls and the rear wall, or the corner of the right wall and the rear wall, of inner container 12. This arrangement prevents drain channel 28 and drain pipe 3 from freezing.

[0132] In this embodiment, the bottom wall of the water receiving tray 250 is inclined relative to the horizontal direction. In one embodiment, the inclination direction of the bottom wall of the water receiving tray 250 is consistent with the inclination direction of the fan housing 230. The lower end of the bottom wall of the water receiving tray 250 is recessed downward to form a water guide groove 252. The bottom wall of the water guide groove 252 is inclined relative to the horizontal direction. A drain portion 251 is provided at the lower end of the bottom wall of the water guide groove 252. The wall of the inner tank 12 can be formed with a drain opening opposite the drain portion 251, and the drain portion 251 extends into the drain opening.

[0133] In one embodiment, the bottom wall of the water receiving tray 250 is inclined from front to back, and the rear end of the water receiving tray 250 is recessed downward to form a water guide groove 252. The water guide groove 252 is inclined from right to left, and a drainage portion 251 is provided at the left end of the water guide groove 252. A drainage opening cooperating with the drainage portion 251 is formed on the left wall of the inner liner 12, and the drainage channel 28 is provided in the foam layer on the left side of the inner liner 12.

[0134] In this embodiment, the water receiving tray 250 may be provided with a plurality of spaced support ribs 253 for supporting the heating element 270 and the heat conducting shield 260. In one embodiment, the support ribs 253 are provided in a plurality of parallel and spaced arrangement. Each support rib 253 extends in the front-to-back direction.

[0169] In this embodiment, the installation method of the refrigerator 100 further includes, after the embedded frame 2 is set on the top of the outer wall of the freezing / temperature-changing liner 12 and before the box shell mold and the liner mold are closed:

[0170] Connect the upper end of the water pipe protective tube 5 to the bottom wall of the refrigerated inner container 19 with the upper end opening of the water pipe protective tube 5 facing the second opening, and insert the lower end of the water pipe protective tube 5 into the connecting hole 207;

[0171] Passing the water injection pipe 4 through the foaming space between the freezing / temperature-changing inner tank 12 and the refrigerating inner tank 19 specifically involves passing the water injection pipe 4 through the water pipe protective tube 5 .

[0172] In this embodiment, the refrigerator 100 also includes a lower sealing plug 7 that is mounted on the outside of the water injection pipe 4 and close to the water outlet end of the water injection pipe 4. The lower sealing plug 7 is inserted between the lower end of the water pipe protective tube 5 and the water injection pipe 4. The lower sealing plug 7 seals the gap between the lower end of the water pipe protective tube 5 and the water injection pipe 4.

[0173] In this embodiment, the refrigerator 100 also includes an upper sealing plug 6 that is sleeved on the outside of the water injection pipe 4 and close to the water inlet end of the water injection pipe 4. The upper end of the upper sealing plug 6 is provided with a protrusion extending outward. The protrusion is provided in the refrigeration chamber 191 and is connected to the upper surface of the bottom wall of the refrigeration inner tank 19. The lower end of the upper sealing plug 6 is inserted between the upper end of the water pipe protective tube 5 and the water injection pipe 4. The upper sealing plug 6 seals the gap between the upper end of the water pipe protective tube 5 and the water injection pipe 4.

[0174] In this embodiment, the installation method of the refrigerator 100 further includes, before placing the water injection pipe 4 into the ice making chamber 14, sleeve-mounting the lower sealing plug 7 on the outside of the water injection pipe 4, with the lower sealing plug 7 close to the water outlet end of the water injection pipe 4;

[0175] After the water injection pipe 4 passes through the water pipe protective pipe 5, the following steps further include: inserting a lower sealing plug 7 between the lower end of the water pipe protective pipe 5 and the water injection pipe 4, so that the lower sealing plug 7 seals the gap between the lower end of the water pipe protective pipe 5 and the water injection pipe 4;

[0176] After the water inlet end of the water injection pipe 4 passes through the second opening and before the water inlet end of the water injection pipe 4 is connected to the water outlet of the water storage member, the method further includes:

[0177] Place the upper sealing plug 6 into the cold storage chamber 191, and sleeve the upper sealing plug 6 from the water inlet end of the water injection pipe 4 onto the outside of the water injection pipe 4;

[0178] Insert the lower end of the upper sealing plug 6 through the second opening between the upper end of the water pipe protective tube 5 and the water injection pipe 4, and seal the gap between the upper end of the water pipe protective tube 5 and the water injection pipe 4 with the upper sealing plug 6. At the same time, make the upper end protrusion of the upper sealing plug 6 contact the upper surface of the bottom wall of the refrigerated inner tank 19.

[0179] This arrangement can prevent the cold air in the ice making chamber 14 from entering the refrigerating chamber 191 through the water pipe protective tube 5.

[0180] In one embodiment, the lower sealing plug 7 and the limiting block 8 are integrally provided.

[0181] In this embodiment, an abutment plate 51 is provided at the upper end of the water pipe guard 5. The abutment plate 51 abuts against the lower surface of the bottom wall of the refrigerated inner container 19. The bottom wall of the refrigerated inner container 19 is provided with a limiting rib that contacts the outer edge of the abutment plate 51. This arrangement ensures the accuracy of the installation position of the water pipe guard.

[0182] In this embodiment, a heat-insulating layer is provided outside the water injection pipe 4, and the heat-insulating layer is wrapped around the water injection pipe 4 or is integrally formed with the water injection pipe 4. A heating wire can also be provided outside the water injection pipe 4. Such a configuration can prevent the water injection pipe 4 from freezing.

[0183] Referring to Figures 1, 3, 5, 7, 13, and 15, in this embodiment, refrigerator 100 may further include a VIP panel 9 disposed within the foaming space. VIP panel 9 covers at least the upward projection of evaporation chamber 208. Because the temperature difference between evaporation chamber 208 and refrigeration chamber 191 is significant, and VIP panel 9 is compact and has low thermal conductivity, disposing VIP panel 9 within the foaming space between evaporation chamber 208 and refrigeration chamber 191 effectively reduces the temperature impact of evaporation chamber 208 on refrigeration chamber 191.

[0184] In this embodiment, the area on the bottom wall of the refrigerated liner 19 opposite to the VIP plate 9 has a step 190 with a height difference. The refrigerator 100 also includes a VIP plate bracket 203 arranged in the foaming space. The VIP plate bracket 203 has a fixed plate 204 opposite to the top surface 1902 of the step. The bottom surface of the fixed plate 204 is flush with the bottom surface 1901 of the step. The upper surface of the VIP plate 9 is connected to the bottom surface 1901 of the step and the bottom surface of the fixed plate 204.

[0185] In this embodiment, the VIP plate bracket 203 further includes a positioning rib 206 provided on the fixing plate 204 , and the end of the positioning rib 206 abuts against the step top surface 1902 and the step surface 1903 between the step top surface 1902 and the step bottom surface 1901 .

[0186] In this embodiment, the VIP panel bracket 203 is formed with a plurality of thermal insulation foam material flow openings 205 .

[0187] In one embodiment, the VIP panel bracket 203 and the embedded frame 2 are integrally formed.

[0188] In this embodiment, the storage compartment 13 is a freezer compartment, and the ice making compartment 14 is located inside the freezer compartment.

[0189] In summary, the refrigeration equipment and installation method of the present invention can solve the problem that ice cubes produced by the ice maker 17 are easily contaminated by odors and bacteria in the cold storage room, resulting in unclean ice cubes. The technical solution of the present application can realize a closed and independent ice making chamber 14 in the storage room 13, and a refrigeration system 200 is installed in the ice making chamber 14 specifically for cooling the ice making chamber 14. This can prevent odors or bacteria in the storage room 13 from entering the ice making chamber 14, ensure the cleanliness of the ice making chamber 14, and realize the production of clean ice in the ice making chamber 14. It can also prevent the top wall of the inner tank 12 from deforming during foaming, ensure the fixing strength of the refrigeration system 200 in the ice making chamber 14, and realize the stable fixation of the refrigeration system 200 in the ice making chamber 14. It also facilitates the centralized modular arrangement and installation of the various components of the refrigeration system 200, realizes rapid defrosting of the fan 220 and the evaporator 210, prevents the defrost water drain pipe 3 from freezing, and ensures the coordination between the water injection pipe 4 of the ice maker 17 and the ice maker 17.

[0190] Referring to Figures 18 and 19 , a second embodiment of the refrigeration equipment provided by this application is shown. The primary difference between this embodiment and the first embodiment lies in the drainage-related structure. For ease of description, identical or similar technical features in the second embodiment are numbered the same as those in the first embodiment, and such identical or similar technical features will not be repeated here.

[0191] The drainage channel 28 includes a first drainage channel 2801 and a second drainage channel 2802 connected to each other. The first drainage channel 2801 extends from the wall of the inner liner 12 toward the box shell 11. The drainage portion 251 extends into the first drainage channel 2801 from the opening at the inner liner 12 end of the first drainage channel 2801. The second drainage channel 2802 extends downward and backward from the box shell 11 end of the first drainage channel 2801. The drain pipe 3 is connected to the bottom opening of the second drainage channel 2802.

[0192] Referring to Figure 19, in this embodiment, the drainage portion 251 and the first drainage channel 2801 are both inclined downward, the inclination angle of the bottom wall of the first drainage channel 2801 is greater than the inclination angle of the bottom wall of the drainage portion 251 of the water receiving tray 250, and the drainage end opening of the drainage portion 251 is placed on the inner side directly above the top opening of the second drainage channel 2802.

[0193] 19 , in this embodiment, a gap is formed between the inner wall of the first drainage channel 2801 and the outer wall of the drainage portion 251 , and the cross-sectional dimension of the first drainage channel 2801 gradually increases from the box shell 11 end to the inner tank 12 end.

[0194] Referring to Figures 1 and 18, in this embodiment, the refrigerator 100 also includes a VIP plate arranged in the foaming space, the VIP plate covers the rear wall and left and right side walls of the inner tank 12, the drainage channel 28 is located on the side of the VIP plate close to the inner tank 12, the drain pipe 3 includes a first part located on the side of the VIP plate close to the inner tank 12 and a second part located on the side of the VIP plate close to the box shell 11, and the refrigerator 100 also includes a heating wire, which is arranged in the drainage channel 28 and the first part of the drain pipe 3.

[0195] Because the VIP panel is compact and has excellent thermal insulation properties, covering the left and right side walls and rear wall of the inner liner 12 with the VIP panel improves the thermal insulation of the inner liner 12 and ensures that the temperature of the drain pipe 3 on the VIP panel's housing 11 is always maintained above 0°C, preventing freezing of the drain pipe 3 on the VIP panel's housing 11. Furthermore, heating wires are arranged on the drain pipe 3 and drainage channel 28 on the VIP panel's inner liner 12 to effectively prevent freezing of the drain pipe 3 and drainage channel 28.

[0196] The portion of the drain pipe 3 extending along the left and right side walls of the inner liner 12 is positioned on the inner liner 12 side of the VIP panel covering the left and right side walls of the inner liner 12. The drain pipe 3 extends downward and rearward from the bottom opening of the second drainage channel 2802 to the rear side of the rear wall of the inner liner 12, then passes through the VIP panel covering the rear wall of the inner liner 12 and extends to the side of the VIP panel near the casing 11. After passing through the VIP panel covering the rear wall of the inner liner 12, the drain pipe 3 bends and extends downward. After reaching the lower side of the bottom wall of the inner liner 12, the drain pipe 3 first bends and extends toward the middle of the casing 1, then bends downward and extends into the press chamber 16.

[0197] Since the drain pipe 3 connects the ice-making chamber 14 with the outside air, there is a pressure difference between the ice-making chamber 14 and the outside air, so the outside air will be sucked back into the ice-making chamber 14. Therefore, the drain pipe 3 is bent several times and extended from the top of the compressor chamber 16 into the evaporating dish, which can slow down the outside airflow from being sucked back into the ice-making chamber 14.

[0198] Referring to Figure 19 , in this embodiment, the storage compartment 13 may be a freezer compartment or a temperature-controlled room. A partition 15 may be provided within the freezer compartment or temperature-controlled room. The partition 15, along with the top wall and left and right side walls of the storage compartment 13, defines an ice-making chamber 14. The partition 15 may be a heat-insulating partition 15.

[0199] 20 to 24 , there is shown a refrigeration device according to a third embodiment of the present application, which differs from the refrigeration devices provided in the first and second embodiments mainly in the refrigeration system.

[0200] In conjunction with Figure 1, in this embodiment, an air duct cover 33 may be provided in the inner liner 12, and the air duct cover 33 may be arranged together with the wall of the inner liner 12 to form a storage evaporation chamber 31. A storage evaporator may be provided in the storage evaporation chamber 31, and the storage evaporation chamber 31 may be used to supply cold air to the storage compartment 13. The storage evaporation chamber 31 may be formed with an opening facing the storage compartment 13, and the air duct cover 33 may be used to close the opening of the storage evaporation chamber 31. The air duct cover 33 may be detachably provided in the inner liner 12. A snap may be provided on the edge of the air duct cover 33, and a slot that snaps into engagement with the air duct cover 33 may be provided on the wall of the inner liner 12, so that the air duct cover 33 may be snapped into the inner liner 12, and the removal and installation of the air duct cover 33 may be facilitated.

[0201] In this embodiment, the storage evaporation chamber 31 can be disposed at the rear side of the storage compartment, and the air duct cover 33 can form the rear wall of the storage compartment 13. The air duct cover, together with the rear wall of the inner liner 12, the left and right side walls of the inner liner 12, the top wall of the inner liner 12, and the bottom wall of the inner liner 12, can enclose the storage evaporation chamber 31. A fan can also be disposed within the storage evaporation chamber, and the air duct cover 33 can be formed with an air outlet and an air return outlet. The air outlet and return outlet of the air duct cover 33 can be located below the partition 15, and the return air outlet of the air duct cover 33 can be located at the bottom of the storage compartment 13, and the air outlet of the air duct cover 33 can be located above the return air outlet of the air duct cover 33.

[0202] In other embodiments of the present invention, the storage evaporation chamber 31 can also be set at other positions of the inner liner 12 relative to the storage chamber. For example, the storage evaporation chamber can be set below the storage chamber, and an air duct cover 33 is provided in the inner liner 12. The air duct cover 33 and the bottom wall of the inner liner 12 together enclose the storage evaporation chamber 31, and the air duct cover 33 forms the bottom wall of the storage compartment 13. For another example, the storage evaporation chamber 31 can be set above the storage compartment 13, and an air duct cover 33 is provided in the inner liner 12. The air duct cover 33 and the top wall of the inner liner 12 together enclose the storage evaporation chamber 31, and the air duct cover 33 forms the top wall of the storage compartment 13. For another example, the storage evaporation chamber 31 can be arranged on the left or right side of the storage compartment 13, and an air duct cover 33 is provided in the inner liner 12. The air duct cover 33 and the left or right wall of the inner liner 12 together enclose the storage evaporation chamber 31, and the air duct cover 33 forms the left wall or right wall of the storage compartment 13.

[0203] In this embodiment, the refrigerator 100 can be a T-shaped refrigerator. The housing 1 can be provided with a refrigerated liner, a frozen liner, and a temperature-variable liner. A refrigerated chamber can be formed inside the refrigerated liner, a frozen chamber can be formed inside the frozen liner, and a temperature-variable liner can be formed inside the temperature-variable liner. A refrigerated evaporation chamber can also be formed inside the refrigerated liner, and a frozen evaporation chamber can be formed inside the frozen liner. The refrigerator 100 can also include a refrigerated evaporator disposed in the refrigerated evaporation chamber and a frozen evaporator disposed in the frozen evaporation chamber. The frozen liner and the temperature-variable liner can be arranged side by side, and the refrigerated liner can be arranged above the frozen liner and the temperature-variable liner. An air duct can be provided between the frozen evaporation chamber and the temperature-variable liner, and the frozen evaporation chamber can supply cold air to the temperature-variable liner through the air duct. The ice-making chamber is provided in the freezer compartment or the temperature-variable liner.

[0204] In other embodiments, the refrigerator 100 may be a two-compartment refrigerator having only a refrigerator compartment and a freezer compartment, and the refrigerator compartment and the freezer compartment may be arranged side by side vertically or side by side horizontally. In another embodiment, the refrigerator 100 may be a French-style refrigerator, which includes a refrigerator compartment and a freezer drawer, a temperature-controlled drawer, etc., arranged below the refrigerator compartment.

[0205] 21 and 22 , in this embodiment, the refrigeration system 200 may include a housing 290, an evaporation chamber formed within the housing 290, and an evaporator 210 disposed within the evaporation chamber. By providing an ice-making chamber 14 with independent cooling within the storage compartment 13, ice cubes produced by the ice-making machine 17 within the ice-making chamber 14 can be prevented from being contaminated by odors and bacteria within the storage compartment 13, thereby ensuring the cleanliness of the ice-making chamber 14.

[0206] The refrigeration system 200 may further include an outlet passage 40 for the refrigerant pipe 23 of the evaporator 210 to pass through the evaporation chamber. The outlet passage 40 may include a first channel member 41 and a second channel member 42 radially opposed to each other along the outlet passage 40. The first channel member 41 may be disposed within the housing 290, and the second channel member 42 may be removably mounted to the first channel member 41. During installation, the evaporator 210 may be first installed within the housing 290. The refrigerant pipe 23 that needs to enter and exit the evaporation chamber may then be placed in the first channel member 41. The second channel member 42 may then be mounted to the first channel member 41, so that the second channel member 42 and the first channel member 41 surround the refrigerant pipe 23 and form a complete outlet passage 40.

[0207] Such a configuration can facilitate the installation of the refrigerant pipe 23 and the passage of the refrigerant pipe 23 through the outlet channel 40. At the same time, the diameter of the outlet channel 40 composed of the first channel member 41 and the second channel member 42 can be set smaller to better fit the diameter of the refrigerant pipe 23, thereby better surrounding the outside of the refrigerant pipe 23, reducing the gap between the refrigerant pipe 23 and the outlet channel 40, ensuring the sealing effect of the refrigerant pipe 23, and preventing cold air from leaking from the evaporation chamber.

[0208] In one embodiment of the present application, the refrigeration system 200 may be modular, that is, the refrigeration system 200 is integrated into a module that can be installed independently. During installation, the integrated module of the refrigeration system 200 is installed as a whole in the ice-making chamber 14. During disassembly, the integrated module of the refrigeration system 200 can be removed from the ice-making chamber 14 as a whole, or part of the refrigeration system 200 can be removed from the ice-making chamber 14. In other embodiments of the present application, the refrigeration system 200 may also be non-modular, that is, the various components of the refrigeration system 200 can be installed separately in the ice-making chamber 14.

[0209] In one embodiment of the present application, the refrigeration system 200 further includes a sealing member disposed outside the refrigerant tube 23. When the second channel member 42 is installed on the first channel member 41, the first channel member 41 and the second channel member 42 form an interference fit with the sealing member. The sealing member may be, for example, foam. When the first channel member 41 is installed on the second channel member 42, the first channel member 41 and the second channel member 42 surround and compress the sealing member, thereby better sealing the gap between the refrigerant tube 23 and the outlet passage 40.

[0210] Referring to Figures 23 and 24, in one embodiment of the present application, the inner walls of both the first and second channel members 41, 42 may be provided with ribs 43. The ribs 43 of the first and second channel members 41, 42 may face each other. The ribs 43 may be arc-shaped. This arrangement allows the ribs 43 on the inner sides of the first and second channel members 41, 42 to better squeeze the seal, improving the sealing effect on the outer side of the refrigerant tube 23. In other embodiments, the ribs 43 of the first and second channel members 41, 42 may also be staggered.

[0211] 21 and 22 , in one embodiment of the present application, the shell 290 may include a second shell 292 and a first shell 291 detachably connected to the second shell 292. The second shell 292 and the first shell 290291 may be snap-fitted to each other or connected via a connector. The first channel member 41 may be fixed to the second shell 292. The first channel member 41 may be integrally provided with the second shell 292 or may be split. The evaporator 210 is mounted on the second shell 292. This arrangement facilitates the coordination between the first channel member 41 and the refrigerant pipe 23, and also facilitates the assembly and disassembly of the first shell 291. When the first shell 291 is disassembled and assembled, the refrigeration evaporator, the refrigerant pipe 23 and the outlet channel 40 will not be affected, and the design is more reasonable without mutual interference.

[0212] The second housing 292 is placed above the first housing 291. The first channel member 41 can be arranged above the second channel member 42. The first channel member 41 is arranged at the bottom end of the wall of the second housing 292. A clearance hole 43 is formed at the top end of the wall of the first housing 291 to cooperate with the outlet pipe channel 40. The upper end of the clearance hole 43 is open, and the end of the second channel member 42 extends into the clearance hole 43. During installation, the second channel member 42 can be installed in the second housing 292 first, and then the first housing 291 can be installed. The inner wall of the clearance hole 43 can be in contact with the inner wall of the end of the second channel member 42, so that the second channel member 42 can be better fixed by using the first housing 291.

The air duct cover 33 may be formed with a clearance opening 34 that cooperates with the outlet pipe channel 40, and the outlet pipe channel 40 may extend into the storage evaporation chamber 31 through the clearance opening 34. The outlet pipe channel 40 may be disposed on the rear side of the housing 290. The first channel member 41 may be formed by a rearward extension of the rear wall of the second housing 292. The refrigerant pipe 23 extends into the storage evaporation chamber 31 through the outlet pipe channel 40.

[0214] Referring to Figures 20 and 21 , and in conjunction with Figure 2 , the refrigeration equipment may include a compressor compartment 16 disposed at the bottom of the housing, which may contain components such as a compressor and a condenser. A refrigerant pipe 32 connected to the compressor, condenser, and other components may be disposed within the storage evaporation chamber 31.

In other embodiments of the present invention, the refrigerant tube 23 can also be connected to the refrigerant pipe 32 by a connecting ring or the like. Such an arrangement can achieve a stable connection between the refrigerant tube 23 and the refrigerant pipe 32.

[0218] Referring to Figure 3, in one embodiment of the present application, a clearance opening 34 is provided at the top of the air duct cover 33 and is open at its upper end. The inner wall of the clearance opening 34 can be aligned with the outer wall of the outlet pipe 40 to ensure a seal between the clearance opening 34 and the outlet pipe 40. During installation, the refrigeration system 200 can be first installed in the ice making chamber 14, with the outlet pipe 40 extending to the top of the storage evaporation chamber 31. The air duct cover 33 can then be installed, moving from bottom to top until the clearance opening 34 mates with the outlet pipe 40. This arrangement facilitates the installation of the refrigeration system 200 and the air duct cover 33, improving the coordination effect.

[0219] In one embodiment of the present application, the second channel member 42 is clamped to the first channel member 41. The second channel member 42 may be provided with a first clamping structure 421 that is clamped to the top wall of the first channel member 41. The first clamping structure 421 may be a claw. Such a configuration can not only achieve the fixation of the first channel member 41 and the second channel member 42, but also limit the downward movement of the second channel member 42. The second channel member 42 may be provided with a second clamping structure 422 that is clamped to the side wall of the first channel member 41. The second clamping structure 422 may be a clamping opening, and the side wall of the first channel member 41 may be protruding to form a protrusion 412 that cooperates with the second clamping structure 422. It can not only achieve the fixation of the first channel member 41 and the second channel member 42, but also limit the displacement of the second channel member 42.

[0220] In one embodiment of the present application, a first limiting surface 411 is provided at the end of the first channel member 41, which abuts against the end surface of the second channel member 42. The rear end of the first channel member 41 can extend outward to form a limiting flange, the front surface of which is the first limiting surface 411. The first limiting surface 411 abuts against the rear end surface of the second channel member 42 to limit the rearward movement of the second channel member 42.

[0221] In one embodiment of the present application, the second channel member 42 is provided with a second limiting surface 423 that abuts against the bottom wall of the first channel member 41. The second limiting surface 423 can be formed on the upper surface of the inner rib 43 of the second channel member 42, and the second limiting surface 423 can abut against the bottom surface of the rib 43 of the first channel member 41 to limit the upward movement of the second channel member 42.

[0222] In one embodiment, the water receiving tray 250 and the evaporator 210 are arranged in the evaporation chamber 208. The shell 290 can be connected to the embedded frame. The shell 290 can be connected to the embedded frame by fasteners such as screws passing through the first shell 291 and the second shell 292. The refrigeration system includes a refrigeration system integrated module. The refrigeration system integrated module includes a shell 290 and an evaporator 210 installed in the shell 290 and a water receiving tray 250. The refrigeration system integrated module also includes a fan 220 that can be installed in the shell 290, a fan 220 fan bracket 240, a heating element, a heat-conducting protective plate, an insulation layer, etc. In this embodiment, the structure and assembly method of the water receiving tray 250, the fan 220, the fan 220 fan bracket 240, the evaporator 210, the heating element, the heat-conducting protective plate, and the insulation layer of the refrigeration system integrated module 300 can be the same as or different from other embodiments in this application.

[0223] In one embodiment of the present application, the refrigeration system 200 includes a second housing integrated module and a first housing integrated module.

[0224] In this embodiment, the second shell integrated module may include a second shell 292 and an evaporator 210 installed on the second shell 292, an outlet pipe channel 40, and a first heating element for defrosting the evaporator 210. The evaporator 210 can be connected to the second shell 292 by screws, snaps and other structures. The first heating element can be installed on the evaporator 210 by snap-fitting or other means. Preferably, the first heating element can be a heating wire, which can be embedded in the inside of the evaporator 210 to better heat the evaporator 210. When the evaporator 210 stops cooling, the first heating element can be started to heat and melt the frost condensed during the cooling period of the evaporator 210, thereby ensuring the cooling effect when the evaporator 210 starts cooling again and improving the ice making efficiency. In other embodiments, the first heating element can be arranged on one side of the evaporator.

[0225] In this embodiment, the first housing integrated module may include a first housing 291, a fan 220 mounted on the first housing 291, and an ice-making water receiving tray 250 for receiving defrosted water from the evaporator 210.

[0228] In summary, the refrigeration equipment of the present application can solve the problem that the ice cubes produced by the ice maker 17 are easily contaminated by the odor and bacteria in the storage compartment 1313, resulting in the prepared ice cubes being unclean.

[0229] By adopting the technical solution of the present application, an ice-making chamber 14 with independent cooling can be set in the storage compartment 13, and the ice cubes made by the ice maker 17 in the ice-making chamber 14 can be prevented from being contaminated by the odor and bacteria in the storage compartment 13, thereby ensuring the cleanliness of the ice-making chamber 14, and facilitating the installation of the refrigerant pipe 23 and the passage of the refrigerant pipe 23 through the outlet pipe channel 40. At the same time, the diameter of the outlet pipe channel 40 composed of the first channel member 41 and the second channel member 42 can be set to be smaller to better fit the diameter of the refrigerant pipe 23, thereby better surrounding the outside of the refrigerant pipe 23, reducing the gap between the refrigerant pipe 23 and the wall of the outlet pipe channel 40, squeezing the seal, ensuring the sealing effect of the refrigerant pipe 23, and preventing the cold air from leaking from the evaporation chamber. The outlet pipe channel 40 and the evaporator 210 are both set in the second shell 292. It can facilitate the coordination between the outlet pipe 40 and the refrigerant pipe 23, and can also facilitate the disassembly and assembly of the first shell 291. When the first shell 291 is disassembled and assembled, it will not affect the refrigeration evaporator, the refrigerant pipe 23 and the outlet pipe 40. The design is more reasonable and will not interfere with each other.
