[0036] The following describes this patent in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit this patent, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0037] The refrigeration equipment of this patent can be a refrigerator, a freezer or a commercial display cabinet, etc. The specific implementation method of this patent will be described below using a refrigerator as an example.

[0038] Reference Figure 1 and Figure 2The refrigerator 100 includes a housing 1, which includes a housing shell 11, an inner container 12 disposed within the housing shell 11, and a foaming space formed between the housing shell 11 and the inner container 12. The foaming space can be filled with a foam insulation material to form a foam layer for insulation. 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, etc.

[0039] 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.

[0040] 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.

[0041] In this embodiment, an ice-making chamber 14 is provided within the storage compartment 13. Preferably, the refrigeration device may include a partition 15 disposed within the storage compartment 13. The partition 15 and the sidewalls of the storage compartment 13 enclose the ice-making chamber 14. The partition 15 may be an insulating partition. Preferably, the ice-making chamber 14 is located at the top of the storage compartment 13. The partition 15 may be installed within the box body 1 after the box body 1 is foam-molded 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] Reference Figure 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 13 . The refrigeration system 200 includes an evaporator 210 .

[0045] In this embodiment, the housing 1 may also be equipped with additional evaporators 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 be equipped with 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 inner container to form a refrigerator compartment and a freezer inner 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 for providing cooling to the refrigerator compartment and a freezer evaporator for providing 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 simultaneously provide cooling to the storage compartment 13, the refrigerator compartment, and the freezer compartment. The evaporators in 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] Reference Figure 1 、 Figure 3 、 Figure 4 In one embodiment of the present invention, the refrigeration system 200 may include a refrigeration system housing 290 . The evaporator 210 may be installed in a space formed by the refrigeration system housing 290 .

[0048] In this embodiment, the refrigeration system 200 may further include a fan assembly. The fan assembly may be pre-installed in the refrigeration system 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.

[0049] In this embodiment, the refrigeration system 200 may further include a drainage assembly. The drainage assembly may be mounted on the housing of the evaporator 210. The drainage assembly may include a water receiving pan 250, a heating element 270, and the like.

[0050] In this embodiment, the fan assembly and the drainage assembly can be pre-installed in the refrigeration system housing 290 and the refrigeration system housing 290 to form a refrigeration system housing integrated module 300.

[0051] 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 refrigeration system housing integrated module 300 in the refrigeration system 200 can be installed in the ice-making chamber 14. Of course, in other embodiments, the refrigeration system housing integrated module 300 can also include the evaporator 210.

[0052] In this embodiment, the refrigeration system housing 290 and the wall of the ice-making chamber 14 can form a relatively closed evaporation chamber 208, and the evaporator 210 and the fan assembly can be disposed within the evaporation chamber 208. The refrigeration system 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 to reduce 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.

[0053] 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.

[0054] like Figure 1 and Figure 3 As shown, in a specific embodiment of the present invention, the ice maker 17 and the refrigeration system 200 can both be installed at 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 of the ice making chamber. A return air vent 292 is formed at the front end of the refrigeration system housing 290, and an air outlet 291 is formed at the rear end of the refrigeration system 200, on the side facing 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 started, the cold air in the evaporation chamber 208 flows from the rear air outlet 291 toward the side where the ice maker 17 is located, and then flows from back to front on the side of the ice maker 17 in the ice-making chamber 14. After flowing through the ice maker 17 from back to front, the cold air flows from the side of the ice maker 17 in the ice-making chamber 14 toward the side where the refrigeration system 200 is located. The cold air flows from front to back on the side of the refrigeration system 200 in the ice-making chamber 14 and enters the evaporation chamber 208 through the front air return port 292. In this way, the refrigeration system 200 can blow cold air from the rear side to the ice maker 17 and draw air from the front side, thereby fully cooling the ice maker 17.

[0055] Furthermore, in this embodiment, the evaporator 210 can be disposed in front of the evaporation chamber 208, and the front end of the evaporator 210 can be opposite the return air outlet 292. The fan 220 can be disposed in the rear of the evaporation chamber 208. An air duct can be formed between the fan 220 and the air outlet 291. The air duct between the fan 220 and the air outlet 291 can be configured to have a certain slope, for example, the air duct from the fan 220 to the air outlet 291 gradually slopes downward. This configuration can prevent the defrosting heat from concentrating when the fan 220 or evaporator 210 is defrosting, thereby reducing the impact of the defrosting heat on the ice in the ice storage box. The evaporator 210 is located in front of the fan 220. After the air in the ice-making chamber 14 enters the evaporation chamber 208 from the return air port 292, it flows from front to back in the evaporation chamber 208, first flows through the front evaporator 210 and fully exchanges heat with the evaporator 210, then flows to the rear fan 220, and under the action of the fan 220, flows from the rear air outlet 291 to the ice-making chamber 14.

[0056] In this embodiment, the refrigeration system 200 and the ice maker 17 can be installed first, and then the partitions can be installed to form the ice making chamber 14. Figure 1 、 Figure 5 and Figure 6 In one embodiment of the present invention, the refrigerator 100 further includes an embedded frame 2. The embedded frame 2 may include an embedded portion 20 disposed within the foaming space and a connecting portion 21 disposed within the ice making chamber 14. In this embodiment, the refrigeration system 200 may be connected to the connecting portion 21 of the embedded frame 2.

[0057] The ice maker 17 and the refrigeration system 200 can be arranged left and right along the width direction of the box body 1. Specifically, in this embodiment, the refrigeration system 200 and the ice maker 17 can be installed on the top of the ice making chamber 14, and the ice maker 17 is also connected to the connecting portion 21 of the embedded frame 2.

[0058] Reference Figures 1 to 6 Furthermore, in this embodiment, a method for installing the refrigerator 100 is also provided, and the installation method includes:

[0059] Fixing the box shell 11 of the refrigerator 100 to the box shell mold;

[0060] 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 part includes a connecting portion 21 that 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;

[0061] Combine the box shell mold and the liner mold;

[0062] Fill the foaming space between the box shell 11 and the inner liner 12 with foam insulation material;

[0063] Separate the refrigerator 100 from the shell mold and the liner mold;

[0064] The refrigeration system 200 of the refrigerator 100 is placed in the ice-making chamber 14 on the top of the storage compartment 13 of the inner tank 12 , and the refrigeration system 200 is connected to the connection portion 21 of the embedded frame 2 .

[0065] 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.

[0066] Reference Figure 3 and Figure 5 Furthermore, in this embodiment, the refrigeration system 200 includes a refrigeration system housing 290. The refrigeration system housing 290 is connected to the top wall of the ice making chamber 14 to form an evaporation chamber 208. The evaporator 210 is located in the evaporation chamber 208. The refrigeration system housing 290 can be connected to the connection portion 21 of the embedded frame 2.

[0067] Preferably, an insulation layer 280 is provided between the evaporation chamber 208 and the ice making chamber 14 . The insulation layer 280 is provided inside the refrigeration system housing 290 and is located within the evaporation chamber 208 .

[0068] Reference Figure 6 and Figure 7 Furthermore, 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 refrigeration system housing 290. The main plate 22 may also completely cover the top wall of the inner liner 12. This arrangement can prevent 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.

[0069] Reference Figure 6 and Figure 7 In this embodiment, the embedded part 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. Preferably, 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 this 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 top of the inner liner 12, the accuracy of the installation position of the embedded frame 2 can be guaranteed.

[0070] In this embodiment, the main board 22 and the positioning plate 23 are integrally formed. In other embodiments of this patent, the main board 22 and the positioning plate 23 may also be provided separately. The provision of the main board 22 and the positioning plate 23 of the embedded frame 2 ensures that the top wall of the liner 12 and the refrigeration system housing 290 are aligned, avoiding gaps at the junction of the refrigeration system housing 290 and the top wall of the liner 12, ensuring the sealing of the evaporation chamber 208 and preventing localized frost.

[0071] Reference Figure 2 、 Figure 6 and Figure 7 Furthermore, 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.

[0072] Preferably, a clamping member 25 for securing the refrigerant tube 18 may be provided in the receiving groove 24. Before the evaporator 210 is installed in the inner liner 12, the refrigerant tube 18 may be placed in the receiving groove 24 and secured with the clamping member 25 in the receiving groove 24 to prevent the refrigerant tube 18 from extending into the inner side of the inner liner 12. When the evaporator 210 is installed in the inner liner 12, the refrigerant tube 18 may be disengaged from the clamping member 25 and allowed to extend from the opening of the receiving groove 24 into the ice-making chamber 14 and connect to the evaporator 210.

[0073] Reference Figures 1 to 7 Furthermore, in this embodiment, the installation method of the refrigerator 100 includes:

[0074] 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.

[0075] 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;

[0076] Fix the inner liner 12 to the inner liner mold;

[0077] 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;

[0078] Combine the box shell mold and the liner mold;

[0079] Fill the foaming space between the box shell 11 and the inner liner 12 with foam insulation material;

[0080] Separate the refrigerator 100 from the shell mold and the liner mold;

[0081] The evaporator 210 is installed in the ice making chamber 14 of the storage compartment 13 of the inner tank 12;

[0082] The refrigerant pipe 18 and the evaporator 210 are connected.

[0083] Since the box body 1 needs to extend the inner liner mold into the inner liner 12 and make the inner liner mold fit the inner wall of the inner liner 12 to avoid deformation of the inner liner 12, the refrigerant tube 18 hanging in the ice-making chamber 14 is easily damaged. The design scheme of this patent can protect the refrigerant tube 18 and effectively avoid the interference between the refrigerant tube 18 and the inner liner mold during foaming of the box body 1, resulting in damage to the refrigerant tube 18. The inner liner mold also does not need to have an avoidance structure for the refrigerant tube 18. The structure is simpler and can better ensure the fit between the foaming mold and the inner liner 12, avoiding deformation of the inner liner 12 due to foaming.

[0084] 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 refrigeration system shell 290 and the embedded frame 2. The evaporator 210 can be installed to the embedded frame 2 first, and then the refrigeration system shell 290 can be installed to the embedded frame 2.

[0085] Reference Figures 3 to 6 Furthermore, in this embodiment, the evaporator 210 is connected to the connection portion 21 of the embedded frame 2. The evaporator 210 includes a first end 211 and a second end 212 that are spaced apart from each other. The first end 211 is provided with a positioning structure 213, and the second end 212 is provided with a snap-fit structure 214. The connection portion 21 of the embedded frame 2 is provided with a positioning matching structure 26 that matches the positioning structure 213 and a snap-fit matching structure 27 that matches the snap-fit matching structure 214. The evaporator 210 is connected to the connection portion 21 of the embedded frame 2 through the matching of the positioning structure 213 with the positioning matching structure 26 and the matching of the snap-fit matching structure 214 with the snap-fit matching structure 27.

[0086] Preferably, 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, and the connecting structure 215 is connected to the embedded part 20 of the embedded frame 2 through a connecting piece.

[0087] Reference Figures 3 to 6 Furthermore, in this embodiment, the installation method of the refrigerator 100 further includes:

[0088] After the clamping structure 214 at the rear end of the evaporator 210 is clamped to the clamping matching structure 27 of the connecting portion 21 of the embedded frame 2 , the positioning structure 213 at the front end of the evaporator 210 is connected to the positioning matching structure 26 of the connecting portion 21 of the embedded frame 2 .

[0089] Reference Figures 3 to 6 Furthermore, in this embodiment, the installation method of the refrigerator 100 further includes:

[0090] After the positioning structure 213 at the front end of the evaporator 210 is connected to the positioning matching structure 26 of the connecting portion 21 of the embedded frame 2, the connecting structure 215 at the front end of the evaporator 210 is connected to the embedded portion 20 of the embedded frame 2 through a connecting piece.

[0091] Furthermore, 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 and are fixedly connected to the evaporator coil 218. The front ends of the first connecting member 216 and the second connecting member 217 are provided with a positioning structure 213 and a connecting structure 215, and the rear ends of the first connecting member 216 and the second connecting member 217 are provided with a clamping structure 214.

[0092] Furthermore, in this embodiment, the first connecting member 216 and the second connecting member 217 each include a main fixing plate 2161 fixedly connected to the evaporator coil 218, a front fixing plate 2162 disposed at the top of the front end of the main fixing plate 2161, and a rear fixing plate 2163 disposed at the top of the rear end of the main fixing plate 2161. The front fixing plate 2162 and the rear fixing plate 2163 may both extend horizontally and may be perpendicular to the main fixing plate 2161.

[0093] In this embodiment, the positioning structure 213 can be a positioning hole 213 provided in the front fixing plate 2162. The positioning and matching structure 26 can be a positioning post 26 provided in the connecting portion 21 of the embedded frame 2. Positioning is achieved by inserting the positioning post 26 into the positioning hole 213. The connecting structure 215 can be a connecting hole 215 provided in the front fixing plate 2162. The connecting member can be a screw or bolt. The connecting member can pass through the connecting hole 215 through the top wall of the inner liner 12 and connect to the main board 22 of the embedded component.

[0094] In this embodiment, the engaging structure 214 can be a slot 214 provided in the rear fixing plate 2163. The engaging structure 27 can be a hook 27 that engages with the slot 214. The slot 214 can extend in the left-right direction, with the left-right width of the slot 214 being greater than the left-right width of the hook 27, allowing the hook 27 to slide left-right within the slot 214. Preferably, the left-right width of the slot 214 can be at least twice the left-right width of the hook 27. This arrangement enables fine-tuning of the left-right position of the evaporator 210.

[0095] Preferably, the hook 27 includes a support portion 271 located below the rear fixing plate 2163 and connected to the bottom surface of the rear fixing plate 2163, a boss portion 273 extending upward from the support portion 271 into the slot 214, and a connecting portion 272 located at the rear side of the rear fixing plate 2163 and connecting the support portion 271 to the main board 22 of the embedded frame 2. The boss portion 273 extends into the slot 214 to serve as a limiter. Preferably, the upper end of the support portion 271 of the hook 27 connects to the bottom surface of the rear fixing plate 2163 located in front of the slot 214. Simultaneously, the upper end of the support portion 271 of the hook 27 also connects to the bottom surface of the rear fixing plate 2163 located behind the slot 214, thereby increasing the contact area between the hook 27 and the rear fixing plate 2163, thereby more stably supporting the evaporator 210.

[0096] Furthermore, in this embodiment, the first connecting member 216 and the second connecting member 217 may both be made of aluminum plates.

[0097] When installing the evaporator 210, place the evaporator 210 in the ice making chamber 14 and close to the top wall of the inner tank 12. The evaporator 210 can be tilted at a certain angle in the front-to-back direction so that the rear end of the evaporator 210 is higher than the front end. After moving the evaporator 210 backward to a certain distance, the evaporator 210 can be slightly shaken in the left and right directions so that the boss portion 273 of the hook in the connecting portion 21 of the embedded frame 2 can extend into the slot 214 of the rear fixing plate 2163 of the evaporator 210. When the hook 27 is engaged with the slot 214, it indicates that the evaporator 210 is With the depth direction of the housing 1 already determined and in place, move the front end of the evaporator 210 upward and rock the evaporator 210 left and right to align the positioning posts 26 in the connection portion 21 of the embedded frame 2 with the connection holes 215 of the front fixing plate 2162 of the evaporator 210. Insert the positioning posts into the connection holes 215. At this point, the left and right positions of the evaporator 210 have been determined and in place. Screw the fixing screws through the connection holes 215 of the front fixing plate 2162 into the main plate 22 of the embedded frame 2, thereby connecting the evaporator 210 to the embedded frame 2. This arrangement allows for convenient positioning and installation of the evaporator 210 on top of the liner 12.

[0098] Reference Figure 3 、 Figure 4 and Figure 8 Furthermore, in one embodiment of the present invention, refrigeration system 200 includes a fan 220 and a fan housing 230. Fan 220 is disposed within fan housing 230. Fan housing 230 is tilted relative to the horizontal. Accordingly, fan 220 is also tilted relative to the horizontal. A drain outlet 231 is formed at a lower position of fan housing 230.

[0099] In this embodiment, the refrigeration system 200 may include an evaporator 210 and a refrigeration system housing 290. The refrigeration system housing 290 and the wall of the ice-making chamber 14 are connected to form an evaporation chamber 208. The fan 220 may be installed in the fan housing 230 first, and then the fan housing 230 may be pre-installed in the refrigeration system housing 290 and the refrigeration system housing 290 to form a refrigeration system housing integrated module 300. The evaporator 210 may be installed in the ice-making chamber 14 first, and then the refrigeration system housing integrated module 300 may be installed.

[0100] Reference Figure 3 、 Figure 4 ,and Figure 9 Furthermore, in this embodiment, the refrigeration system 200 also includes a water collection pan 250 with an open top. The refrigeration system housing integrated module 300 may include the water collection pan 250, which may be pre-installed in the refrigeration system housing 290 to form the refrigeration system housing integrated module 300. The fan housing 230 may be located above the water collection pan 250. By arranging the fan 220 and the fan housing 230 at an angle, the flow and collection of water on 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.

[0101] Reference Figure 3 and Figure 10 Furthermore, in this embodiment, the refrigeration system 200 also includes a fan bracket 240. The refrigeration system housing integrated module 300 may include a fan bracket 240, and the fan bracket 240 may be pre-installed in the refrigeration system housing 290 to form the refrigeration system housing integrated module 300. The fan bracket 240 may be located above the water receiving tray 250. The fan bracket 240 includes a support plate 241. The support plate 241 is disposed above the water receiving tray 250 and is inclined relative to the horizontal direction. 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.

[0102] Preferably, 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.

[0103] Reference Figure 3 and Figure 11Furthermore, in this embodiment, the refrigeration system 200 includes a heating element 270. The refrigeration system housing integrated module 300 may include a heating element 270, and the heating element 270 may be pre-installed in the refrigeration system housing 290 to form the refrigeration system 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 wire, 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, and the defrosting of the fan 220 can be more thorough, thereby ensuring the life of the fan 220.

[0104] Reference Figure 3 and Figure 11 Furthermore, in this embodiment, the refrigeration system 200 also includes a heat-conducting shield 260. The refrigeration system housing integrated module 300 may include the heat-conducting shield 260. The heat-conducting shield 260 may be pre-installed in the refrigeration system housing 290 to form the refrigeration system 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. The heater 270 and the fan bracket 240 are both connected to the heat-conducting shield 260.

[0105] Preferably, 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, the 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. However, if the drain openings 261 are too small, the drainage effect will be affected. The design solution provided in this embodiment has a moderately sized drain opening 261, which prevents air from passing through the drain openings 261 and flowing directly from the space between the heat-conducting shield 260 and the water tray 250 to the fan 220, thereby ensuring drainage and cooling efficiency.

[0106] Furthermore, 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-conducting shield 260 .

[0107] Reference Figure 3 and Figure 11Furthermore, 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 .

[0108] Furthermore, in this embodiment, the heater 270 is located above the water tray 250. The 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.

[0109] 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.

[0110] Reference Figure 3 and Figure 10 In this embodiment, the fan bracket 240 further includes ribs 242 extending downward from the support plate 241 to connect with the heat-conducting shield 260. Preferably, the lower ends of the ribs 242 are provided with protruding edges 243 extending along the heat-conducting shield 260. The ribs 242 of the fan bracket 240 serve to guide water, and the protruding edges 243 at the ends of the ribs 242 increase the contact area between the fan bracket 240 and the heat-conducting shield 260.

[0111] Reference Figure 3 Furthermore, in this embodiment, the evaporator 210 is located above the heat-conducting shield 260 and the heater 270. The evaporator 210 can be arranged horizontally. The heat-conducting shield 260 covers the underside of the evaporator 210. The evaporator 210 can include 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.

[0112] 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.

[0113] Reference Figure 1 、 Figure 3 and Figures 8 to 11Preferably, the water receiving tray 250 , the heating element 270 and the heat conductive shield 260 are arranged at the bottom of the evaporation chamber 208 , and the fan 220 is arranged at the top of the evaporation chamber 208 .

[0114] Furthermore, in this embodiment, the evaporator 210 is arranged in front of the fan 220. The ice maker 17 and the refrigeration system 200 can be arranged side by side along the width direction of the cabinet 1. The refrigeration system housing 290 is formed with an air outlet 291 and a return air outlet 292 that connect the evaporation chamber 208 and the ice making chamber 14. The return air outlet 292 is arranged at the front end of the evaporation chamber 208. The evaporator 210 can be arranged at the front of the evaporation chamber 208, and the front end of the evaporator 210 can be opposite to the return air outlet 292. The air outlet 291 is arranged at the rear end of the evaporation chamber 208. The fan 220 can be arranged at the rear of the evaporation chamber 208, and the air outlet 291 can be located on the ice maker 17 side of the fan 220. The air outlet 291 is arranged at the rear side of the ice maker 17. The air outlet 291 can be opposite to the ice maker 17.

[0115] 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.

[0116] When the fan 220 is started, the cold air in the evaporation chamber 208 flows from the rear air outlet 291 to the side where the ice maker 17 is located, and flows from back to front on the side where the ice maker 17 is located in the ice making chamber 14. After the cold air flows through the ice maker 17 from back to front, it flows from the side where the ice maker 17 is located in the ice making chamber 14 to the side where the refrigeration system 200 is located. The cold air flows from front to back on the side where the refrigeration system 200 is located in the ice making chamber 14 and enters the evaporation chamber 208 through the front air return port 292. The air entering the evaporation chamber 208 from the ice making chamber 14 first flows through the front evaporator 210 and exchanges heat with the evaporator 210, and then passes through the air outlet 246 of the plate rib 242, the air outlet 244 of the support plate 241 and the opening 232 of the fan casing 230 into the fan casing 230. Under the action of the fan 220, it flows from the rear air outlet 291 to the ice making chamber 14, and the cycle is repeated. In this way, the refrigeration system 200 can blow cold air toward the ice maker 17 from the rear side and draw air from the front side, thereby improving the refrigeration efficiency and fully cooling the ice maker 17 .

[0117] Reference Figure 10Furthermore, in this embodiment, the fan 220 is arranged horizontally. The fan casing 230 is inclined from front to rear. The depth direction of the refrigerator 100 is the front-to-back direction, the compartment opening of the storage compartment 13 faces the front, and the compartment opening direction away from the storage compartment 13 is the rear. A drain outlet 231 is formed at the rear end of the fan casing 230. A drain outlet 245 is formed at the rear end of the support portion. The fan bracket 240 has a plurality of plate ribs 242 that are arranged in parallel and at intervals. Each plate rib 242 of the fan bracket 240 extends in the front-to-back direction, and each plate rib 242 is formed with a plurality of air outlets 246 to facilitate the flow of internal air at the front end of the evaporation chamber 208 to the fan 220.

[0118] Reference Figures 1 to 5 、 Figure 7 、 Figure 9 、 Figure 12 、 Figure 13 Furthermore, in this embodiment, the water tray 250 is provided with a drain portion 251, and the refrigerator 100 also includes a drain pipe 3. The embedded frame 2 is formed with a drainage channel 28 within the foam layer. The drain portion 251 of the water tray 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 corners of the left / right walls and rear wall of the inner container 12. This arrangement facilitates drainage from the water tray 250, prevents water leakage, and effectively prevents the drainage channel 28 and the drain pipe 3 from freezing.

[0119] Furthermore, in this embodiment, the refrigerator 100 also includes an evaporating dish disposed within the compressor compartment 16. The evaporating dish is open at its top, and the drain pipe 3 passes through the foam layer at the corners of the left / right walls and rear wall of the inner container 12 and enters the compressor compartment 16. The drain pipe 3 bends at the top of the compressor compartment 16 and extends into the evaporating dish. Defrosted water from the fan 220 and evaporator 210 flows into the evaporating dish and evaporates naturally therein.

[0120] 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 outside airflow sucked back into the ice-making chamber 14 can be slowed down.

[0121] Furthermore, in this embodiment, a drainage portion 251 is provided at the end of the water receiving tray 250, extending toward the wall of the inner container 12.

[0123] Furthermore, in this embodiment, the drainage portion 251 of the water receiving tray 250 and the first drainage channel 2801 are both inclined downward, and an opening is formed at the end of the drainage portion 251 of the water receiving tray 250. The bottom wall of the first drainage channel 2801 includes a first inclined surface 2803 and a second inclined surface 2804 connected to each other. The first inclined surface 2803 extends from the corner of the first drainage channel 2801 and the second drainage channel 2802 to below the end opening of the drainage portion 251 of the water receiving tray 250, and the second inclined surface 2804 extends from the first inclined surface 2803 to the end opening of the inner tank 12 of the first drainage channel 2801. The inclination angle of the first inclined surface 2803 is greater than the inclination angle of the second inclined surface 2804, and the inclination angle of the second inclined surface 2804 is greater than the inclination angle of the drainage portion 251 of the water receiving tray 250. Preferably, the inclination angle of the drainage portion 251 of the water receiving tray 250 is greater than or equal to 2 degrees, the angle of the first inclined surface 2803 is greater than or equal to 3 degrees, and the angle of the second inclined surface 2804 is greater than or equal to 20 degrees. This arrangement can prevent water in the drainage channel 28 from flowing back and leaking.

[0124] Furthermore, in this embodiment, a gap is provided between the wall of the first drainage channel 2801 and the wall of the drainage portion 251 of the water receiving tray 250. The cross-sectional dimensions of the first drainage channel 2801 gradually increase from the housing 11 end toward the inner liner 12 end. Preferably, the cross-sectional dimensions of the first drainage channel 2801 are trapezoidal. This arrangement facilitates the insertion of the drainage portion 251 of the water receiving tray 250 into the drainage channel 28.

[0125] Furthermore, in this embodiment, the refrigerator 100 further includes a heating wire disposed in the drainage channel 28 and the drainage pipe 3, the heating wire extending from the drainage channel 28 to at least the left / right wall and rear wall corners of the inner container 12. This arrangement can prevent the drainage channel 28 and the drainage pipe 3 from freezing.

[0126] Furthermore, in this embodiment, the bottom wall of the water receiving tray 250 is inclined relative to the horizontal direction. Preferably, 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 water inlet end of the water injection pipe 4 is placed in the refrigerating chamber 191 and is connected to the water outlet of the water storage component. A limiting block 8 is fixed to the water injection pipe 4 near the water outlet end. The limiting block 8 abuts against the first opening side of the connecting hole 207, and the limiting block 8 is larger than the aperture of the connecting hole 207.

[0151] Furthermore, in this embodiment, the installation method includes:

[0152] Fixing the box shell 11 of the refrigerator 100 to the box shell mold;

[0153] The freezer / temperature-variable liner 12 of the refrigerator 100 and the refrigerated liner 19 placed above the freezer / temperature-variable liner 12 are fixed to the liner mold, and the embedded frame 2 is set on the top of the outer wall of the freezer / temperature-variable liner 12 so that the embedded frame 2 covers the first opening formed on the top wall of the freezer / temperature-variable liner 12.

[0160] The water inlet end of the water injection pipe 4 is placed in the refrigeration chamber 191 inside the refrigeration liner 19 and connected to the water outlet of the water storage member inside the refrigeration chamber 191;

[0161] The ice maker 17 is installed in the ice making chamber 14 , and the water outlet end of the water injection pipe 4 is placed in the ice making chamber 14 and cooperates with the ice maker 17 .

[0162] Such a setting can reduce the leakage points of the water injection water channel of the ice maker 17, and can ensure the coordination between the water outlet end of the water injection pipe 4 and the ice maker 17, thereby preventing the water outlet end of the water injection pipe 4 from being deflected when the worker pulls the water injection pipe 4 upward when installing the water injection pipe 4.

[0163] Furthermore, in this embodiment, the refrigerator 100 also includes a water pipe protective tube 5, which is arranged outside the water injection pipe 4 and placed in the foaming space.

[0166] 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 .

[0167] Furthermore, in this embodiment, the refrigerator 100 also includes a lower thermal insulation sealing plug 7 which is mounted outside the water injection pipe 4 and close to the water outlet end of the water injection pipe 4. The lower thermal insulation sealing plug 7 is inserted between the lower end of the water pipe protective tube 5 and the water injection pipe 4 and seals the gap between the lower end of the water pipe protective tube 5 and the water injection pipe 4.

[0168] Furthermore, in this embodiment, the refrigerator 100 also includes an upper thermal insulation sealing plug 6 which is mounted 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 thermal insulation 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 liner 19. The lower end of the upper thermal insulation sealing plug 6 is inserted between the upper end of the water pipe protective tube 5 and the water injection pipe 4 and seals the gap between the upper end of the water pipe protective tube 5 and the water injection pipe 4.

[0169] Furthermore, 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 heat-insulating sealing plug 7 on the outside of the water injection pipe 4 and close to the water outlet end of the water injection pipe 4;

[0170] After the water injection pipe 4 passes through the water pipe protective pipe 5, the following steps are further included: inserting the lower insulation sealing plug 7 between the lower end of the water pipe protective pipe 5 and the water injection pipe 4 to seal the gap between the lower end of the water pipe protective pipe 5 and the water injection pipe 4;

[0171] 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:

[0172] Place the upper heat-insulating sealing plug 6 into the cold storage chamber 191 and sleeve it onto the outside of the water injection pipe 4 from the water inlet end;

[0173] Insert the lower end of the upper thermal insulation 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. At the same time, make the upper end protrusion of the upper thermal insulation sealing plug 6 contact the upper surface of the bottom wall of the refrigerated liner 19.

[0174] 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.

[0178] Reference Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 13 、 Figure 15 Furthermore, in this embodiment, the refrigerator 100 may further include a VIP panel 9 disposed within the foaming space. The VIP panel 9 covers at least the upward projection of the evaporation chamber 208. Because the temperature difference between the evaporation chamber 208 and the refrigeration chamber 191 is large, and the VIP panel 9 is small and has a low thermal conductivity, disposing the VIP panel 9 within the foaming space between the evaporation chamber 208 and the refrigeration chamber 191 effectively reduces the temperature impact of the evaporation chamber 208 on the refrigeration chamber 191.

[0179] 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.

[0180] Furthermore, 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 .

[0181] Furthermore, in this embodiment, the VIP board bracket 203 is formed with a plurality of thermal insulation foam material flow openings 205 .

[0182] Preferably, the VIP plate bracket 203 and the embedded frame 2 are integrally formed.

[0183] Preferably, in this embodiment, the storage compartment 13 is a freezer compartment, and the ice-making compartment 14 is located in the freezer compartment.

[0184] Reference Figure 1 and Figure 18 In another embodiment of the present invention, 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 of the water receiving tray 250 extends into the first drainage channel 2801 from the opening at the inner tank 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.

[0185] Reference Figure 19Furthermore, in this embodiment, the drainage portion 251 of the water receiving tray 250 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 of the water receiving tray 250 is placed on the inner side directly above the top opening of the second drainage channel 2802.

[0186] Reference Figure 19 Furthermore, in this embodiment, there is a gap between the inner wall of the first drainage channel 2801 and the outer wall of the drainage portion 251 of the water receiving tray 250, and the cross-sectional size of the first drainage channel 2801 gradually increases from the box shell 11 end to the inner tank 12 end.

[0187] Reference Figure 1 and Figure 18 Furthermore, 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 inner tank 12 side of the VIP plate, the drain pipe 3 includes a first part located on the inner tank 12 side of the VIP plate and a second part located on the box shell 11 side of the VIP plate, 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.

[0188] Since the VIP board is small in size and has excellent thermal insulation performance, the left and right side walls and the rear wall of the inner liner 12 are covered by the VIP board, which can improve the thermal insulation effect of the inner liner 12, and can also ensure the temperature of the drain pipe 3 on the side of the VIP board box shell 11, so that the temperature of the drain pipe 3 on the side of the box shell 11 can always be maintained above 0°C, avoiding the freezing of the drain pipe 3 on the side of the VIP board box shell 11. At the same time, heating wires are arranged on the drain pipe 3 and the drainage channel 28 on the side of the VIP board inner liner 12, which can effectively avoid the freezing of the drain pipe 3 and the drainage channel 28 on the side of the VIP board inner liner 12.

[0189] The portion of the drain pipe 3 extending along the left and right side walls of the inner liner 12 is placed on the inner liner 12 side of the VIP plate covering the left and right side walls of the inner liner 12. The drain pipe 3 extends downward and backward from the bottom opening of the second drainage channel 2802 to the rear side of the rear wall of the inner liner 12, and then passes through the VIP plate covering the rear wall of the inner liner 12 and extends to the box shell 11 side of the VIP plate. After passing through the VIP plate covering the rear wall of the inner liner 12, the drain pipe 3 bends and extends downward. After extending to 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 box body 1, and then bends downward and extends into the press chamber 16.

[0190] 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.

[0191] Reference Figure 19 Furthermore, in this embodiment, the storage compartment 13 may be a freezer compartment or a temperature-controlled room. A partition 15 may be provided in the freezer compartment or temperature-controlled room. The partition 15, together 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.

[0192] Reference Figure 20 Furthermore, in this embodiment, the refrigeration system also includes a refrigeration system housing 290. The refrigeration system housing 290 may include a first housing 291 and a second housing 292 disposed opposite each other. The second housing 292 is positioned above the first housing 291, and an evaporation chamber 208 is formed between the first and second housings 291 and 292. The water collection tray 250 and the evaporator 210 are disposed within the evaporation chamber 208. The refrigeration system housing 290 may be connected to the pre-buried frame. Fasteners such as screws may be used to connect the refrigeration system housing 290 to the pre-buried frame. The refrigeration system includes an integrated module for the refrigeration system housing 290. The refrigeration system integrated module 300 includes the refrigeration system housing 290, the evaporator 210 mounted within the refrigeration system housing 290, and the water collection tray 250. The refrigeration system integrated module 300 also includes a fan 220, a fan bracket 240, a heater, a heat-conducting shield, and an insulation layer, which may be mounted within the refrigeration system housing 290. In this embodiment, the structure and assembly method of the water receiving tray 250, fan 220, fan 220 fan bracket 240, evaporator 210, heating element, heat conductive shield, and insulation layer of the refrigeration system integrated module 300 can be the same as or different from other embodiments of the present invention.

[0193] For example, in this embodiment, the insulation layer can be first installed in the first shell 291, and then the water receiving tray 250 can be installed in the first shell 291 and placed inside the insulation layer. The assembled heating wire and heat conductive shield can then be installed in the first shell 291 and placed above the water receiving tray 250. The evaporator 210 can then be installed above the heat conductive shield near the front side of the evaporation chamber 208. The fan 220 and the fan bracket 240 can then be installed at the rear side of the evaporation chamber 208, so that the fan 220 and the fan bracket 240 are connected to the rear wall of the first shell 291 and the fan 220 is arranged longitudinally. The second shell 292 and the first shell 291 can then be aligned and connected to form a relatively closed evaporation chamber 208. Finally, the refrigeration system shell 290 can be connected to the embedded frame using fasteners, thereby achieving the overall installation of the refrigeration system integrated module 300. By forming the refrigeration system integrated module 300, the assembly efficiency can be effectively improved.

[0194] 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.
