[0038] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0039] See also Figures 1 to 4 One embodiment of the present invention provides a refrigeration appliance, which may be a refrigerator. Figure 1 This is a simple schematic diagram of a refrigeration appliance according to one embodiment of the present invention. Figure 2 Schematic diagram of the freezer compartment. Figure 3 and Figure 4 for Figure 2 Schematic diagram with some components hidden.

[0040] A refrigeration appliance may include a refrigeration compartment. The refrigeration appliance may include a housing 100, which may include a storage compartment. The storage compartment may include a refrigerator compartment 110, a freezer compartment 120, and a variable temperature chamber. The refrigeration appliance may also include an ice-making compartment 130, which may include an ice-making machine 300. An ice storage box 350 may also be installed in the ice-making compartment 130. The ice storage box 350 may be placed below the ice-making machine 300, and the user may remove the ice storage box 350 from the ice-making compartment 130. The refrigeration compartment may include a storage compartment or the ice-making compartment 130.

[0041] A compressor compartment may be further provided on the side of the housing 100, in which a compressor 150 may be installed. The refrigeration appliance may include a storage evaporator for supplying cold air to the storage compartment and an ice making evaporator 230 for supplying cold air to the ice making compartment 130.

[0042] The storage evaporator may include a refrigeration evaporator 111 for supplying cold air to the refrigerator compartment 110 and a freezer evaporator 121 for supplying cold air to the freezer compartment 120. The storage evaporator and ice-making evaporator 230 may share a compressor 150. By using a separate ice-making evaporator 230 to supply cold air to the ice-making compartment 130, the cold air in the ice-making compartment 130 is kept clean and unaffected by the odor of food stored in the storage compartment, thereby producing clean ice cubes.

[0043] In one embodiment of the present invention, the ice-making compartment 130 is disposed within the freezer compartment 120. The ice-making compartment 130 and the freezer compartment 120 are isolated from each other, meaning that no cold air is exchanged between the ice-making compartment 130 and the freezer compartment 120. The refrigeration appliance includes a freezer door 122 for opening and closing the freezer compartment 120. When the freezer door 122 is closed, the ice-making compartment 130 is sealed. To remove components such as the ice storage box 350 from the ice-making compartment 130, the user must first open the freezer door 122.

[0044] In this embodiment, the refrigeration appliance further includes an ice-making door 131, which can be used to open and close the ice-making chamber 130. The ice-making door 131 can be integrated with the ice storage bin 350. For example, the ice storage bin 350 can be retractable within the ice-making chamber 130, and the front panel of the ice storage bin 350 can form the ice-making door 131. When the freezer door 122 is closed, the ice-making door 131 can be closed, with the freezer door 122 covering the ice-making door 131. To open the ice-making door 131, the user must first open the freezer door 122.

[0045] The box body 100 may include an outer shell and an inner liner, and the space between the outer shell and the inner liner may be filled with a heat-insulating material. In a specific embodiment, the heat-insulating material may be a foam material. The outer shell and the inner liner may be foam-molded to obtain the box body 100. The space inside the inner liner forms a storage compartment. After the box body 100 is manufactured, a partition 140 may be installed in the freezer compartment 120 to directly separate the ice-making compartment 130. The partition 140 may be an insulating partition. In this embodiment, the ice-making compartment may be a space enclosed by the box body and the partition, and a partition may be provided in the ice-making compartment to separate the air duct or an area for installing an evaporator, etc. The partition 140 is sealed from the side wall of the freezer compartment 120, such as by a sealing strip or other structure to prevent cold air exchange between the ice-making compartment 130 and the freezer compartment 120. The partition plate 140 may be disposed at an upper portion of the freezing chamber 120 , and the partition plate 140 may enclose the ice-making chamber 130 together with the top wall and side walls of the freezing chamber 120 .

[0046] Of course, the storage compartment may further include a variable temperature chamber, and the ice making chamber 130 may also be disposed in the variable temperature chamber. The refrigeration appliance may include a variable temperature door for opening and closing the variable temperature chamber. When the variable temperature door is closed, the ice making chamber 130 may be sealed, and the user may need to open the variable temperature door to enter the ice making chamber 130. The method of disposing the ice making chamber 130 in the variable temperature chamber may be substantially the same as the method of disposing the ice making chamber 130 in the freezing chamber 120.

[0047] In one embodiment of the present invention, the refrigeration system of at least one refrigeration compartment can be installed inside the refrigeration compartment. The refrigeration system may include a refrigeration shell, an evaporator installed in the refrigeration shell, and a fan. The refrigeration system may also include a water receiving tray, a defrost heating wire and other components installed inside the refrigeration shell. The refrigeration system may include an air outlet and a return air outlet, and the air outlet and the return air outlet may be directly placed in the refrigeration compartment.

[0048] In a specific embodiment of the present invention, the at least one refrigeration compartment is an ice-making compartment 130 , and an ice-making refrigeration system 200 is installed in the ice-making compartment 130 . The ice-making refrigeration system includes an ice-making evaporator 230 .

[0049] For details, see Figures 5 to 13 , which is a refrigeration appliance according to the first embodiment of the present invention. In this embodiment, an ice-making evaporator 230 is installed inside the ice-making chamber 130. The refrigeration appliance includes an ice-making refrigeration system 200, which may include a refrigeration housing 210 and an ice-making evaporator 230. The ice-making evaporator 230 is located inside the refrigeration housing 210.

[0050] The ice-making refrigeration system 200 may further include a fan 240 and, further, a water receiving tray 250 and a defrosting heating wire, both of which may be located within the refrigeration housing 210. The water receiving tray 250 may be located below the ice-making evaporator 230. When the ice-making evaporator 230 requires defrosting, the defrosting heating wire may be activated to heat the ice-making evaporator 230, and water formed by melting frost on the surface of the ice-making evaporator 230 may flow into the water receiving tray 250.

[0051] The water receiving tray 250 may have a drain nozzle 253, the side wall of the ice making chamber 130 may be provided with a drain port, a drain pipe 255 connected to the drain port may be installed in the insulation layer of the box body 100, the drain nozzle 253 of the water receiving tray 250 may be inserted into the drain port, and the water in the water receiving tray 250 may be discharged to the evaporating dish in the press chamber or directly to the outside of the refrigeration appliance through the drain pipe 255.

[0052] The ice-making refrigeration system 200 may have an air outlet 217 and an air return outlet 218. The cold energy of the ice-making refrigeration system 200 is directly transferred to the ice-making chamber 130 through the air outlet 217, with less cold energy loss, which can greatly improve the ice-making efficiency.

[0053] The air outlet 217 and the return air outlet 218 can both be arranged above the ice storage box 350. In this way, during the defrosting process of the ice-making evaporator 230, since the hot air is not easy to sink, the impact of the defrosting hot air on the ice storage box 350 can be reduced, and the possibility of the ice cubes in the ice storage box 350 melting during the defrosting process of the ice-making evaporator 230 can be reduced. In one embodiment of the present invention, the ice-making evaporator 230 can be arranged beside the ice-making machine 300, that is, the ice-making refrigeration system 200 can be arranged beside the ice-making machine 300. In this embodiment, with the user facing the ice-making machine 300 as a reference, the side can include the left side, right side, front side and back side of the ice-making machine 300.

[0054] In one embodiment of the present invention, the ice-making evaporator 230 is installed on the top of the ice-making chamber 130, that is, the ice-making refrigeration system 200 is installed on the top of the ice-making chamber 130. The ice-making machine 300 can also be installed on the top of the ice-making chamber 130. The ice-making refrigeration system 200 and the ice-making machine 300 can be arranged in parallel.

[0055] Specifically, the ice-making refrigeration system 200 and the ice-making machine 300 can be arranged side by side along the width of the ice-making chamber 130, thereby maximizing the space utilization of the ice-making chamber 130, reducing the internal volume of the ice-making chamber 130, and improving refrigeration efficiency. This ensures that the pressure inside the ice-making chamber 130 is always higher than the pressure inside the freezer chamber 120. When the ice-making chamber 130 and the freezer chamber 120 are separated by a partition 140, odors from the freezer chamber 120 are prevented from entering the ice-making chamber 130 through the gap between the partition 140 and the inner liner of the cabinet 100, thereby contaminating the ice cubes inside the ice-making chamber 130.

[0056] Of course, the ice-making refrigeration system 200 and the ice-making machine 300 may also be arranged side by side front and back along the depth direction of the ice-making chamber 130 , such as the ice-making machine 300 being arranged at the front side and the ice-making refrigeration system 200 being arranged at the rear side.

[0057] In this embodiment, see Figure 7-10 The refrigeration housing 210 includes an upper refrigeration housing 211 and a lower refrigeration housing 212. The upper refrigeration housing 211 is installed in the ice-making chamber 130. Specifically, in this embodiment, the upper refrigeration housing 211 is installed on the top wall of the ice-making chamber 130. The top wall of the ice-making chamber 130 may be provided with a mounting bracket 260, and the upper refrigeration housing 211 can be mounted on the mounting bracket 260. The lower refrigeration housing 212 is detachably mounted on the upper refrigeration housing 211. The lower refrigeration housing 212 and the upper refrigeration housing 211 are engaged to form an ice-making evaporator chamber. The fan 240, the water receiving tray 250, and the defrost heater can all be placed in the ice-making evaporator chamber.

[0058] The ice-making evaporator 230 and fan 240 can be installed in the upper refrigeration housing 211, and the water tray 250 can be installed in the lower refrigeration housing 212. The fan 240 can be removably installed in the upper refrigeration housing 211. During installation, the pre-assembled modules can be directly installed, making the installation process convenient. If a malfunction occurs during use, the lower refrigeration housing 212 can be directly removed for repair.

[0059] See also Figure 10 and Figure 12 The refrigeration upper housing 211 may be provided with a fan mounting slot 241, into which the fan 240 may be mounted by snap fasteners. The fan mounting slot 241 may include side walls and a top wall, each of which may be provided with a shock-absorbing spring. When the fan 240 is fixed to the refrigeration upper housing 211 by snap fasteners, the shock-absorbing spring may increase elasticity and reduce the rigid connection between the fan 240 and the refrigeration upper housing 211, thereby reducing vibration and noise during the operation of the fan 240.

[0060] The fan 240 may have a fan housing, which may form an air outlet duct for the fan 240. The refrigeration upper housing 211 may also be provided with a mounting slot that cooperates with the air outlet duct of the fan 240. Vibration-damping cotton may be provided between the air outlet duct of the fan housing and the refrigeration upper housing 211 to reduce vibration and noise during the operation of the fan 240.

[0061] The fan 240 can be mounted on the refrigeration upper housing 211 at an angle relative to the horizontal plane. Specifically, the air outlet duct of the fan 240 can be tilted downward, and the air outlet 217 of the fan 240 can form an angle of 5°-9° with the horizontal plane. A water tray 250 can be positioned below the fan 240. This allows water in the fan housing to flow out of the air outlet of the fan 240 and into the water tray 250, preventing it from freezing inside the fan 240 and affecting cooling.

[0062] The defrost heating wires within the ice-making refrigeration system 200 can be integrated into the ice-making evaporator 230. The ice-making evaporator 230 can include fins and refrigerant tubes, with the refrigerant tubes passing through the fins and secured thereto. The fins can also be provided with holes for mounting the defrost heating wires, which can also pass through the fins and be secured thereto. Aluminum plates 231 can also be provided at both ends of the ice-making evaporator 230 to protect the defrost heating wires and prevent them from being scratched. The ice-making evaporator 230 can be mounted at an angle to facilitate the drainage of defrost water within the evaporator 230.

[0063] See also Figure 9 and Figure 13The water receiving tray 250 may include a first water receiving portion 251 located below the ice making evaporator 230 and a second water receiving portion 252 located below the fan 240. The first water receiving portion 251 may be wavy, and both the upper and lower surfaces of the first water receiving portion 251 may be wavy.

[0064] A windshield 254 can be provided between the ice-making evaporator 230 and the water tray 250. The windshield 254 can be fixed to the ice-making evaporator 230 and abut the water tray 250, or it can be fixed to the water tray 250 and abut the ice-making evaporator 230. The windshield 254 reduces the amount of cold air flowing through the bottom of the ice-making evaporator 230 during the return air cycle, thereby improving cooling efficiency. Furthermore, the windshield 254 can be a heat-conducting structure, thereby transferring heat from the defrost heater to the water tray 250, preventing the water in the water tray 250 from freezing. During the return air cycle, some of the cold air returning to the refrigeration housing 210 flows through the water tray 250. Since the temperature of the cold air returning to the refrigeration housing 210 is higher than that of the cold air in the ice-making compartment 130, the temperature of the bottom surface of the refrigeration housing 210 can be raised, making the temperature inside the refrigeration housing 210 higher than that inside the ice-making compartment 130.

[0065] The wavy water tray 250 also reduces heat transfer to the outside, minimizing the temperature difference between the interior of the refrigeration housing 210 and the ice-making chamber 130. This allows for the use of a thinner insulation structure, preventing frost from forming inside the refrigeration housing 210. Specifically, the refrigeration housing 210 may be provided with insulating foam 270, which may be 5mm EPS foam with a density of 30-40 kg / m³.

[0066] The second water receiving portion 252 of the water receiving tray 250 can be flat, thereby increasing the distance between the second water receiving portion 252 and the fan 240 and providing space for the fan 240 to draw air. The second water receiving portion 252 of the water receiving tray 250 can be equipped with a drain nozzle. An aluminum foil heater can be installed on the second water receiving portion 252, which can extend into the drain nozzle 253. This prevents the drain nozzle 253 and the corresponding drain outlet of the cabinet 100 from freezing during drainage, ensuring smooth discharge of defrosted water. The flat structure of the second water receiving portion 252 also facilitates the installation of the aluminum foil heater.

[0067] The upper refrigeration housing 211 and the lower refrigeration housing 212 can be provided with mutually cooperating pipe outlet holes 219, through which the air inlet pipe and the air return pipe of the ice-making evaporator 230 can pass. A sealing flexible member can be provided over the air inlet pipe and the air return pipe of the ice-making evaporator 230. The sealing flexible member can be made of foam. When the upper refrigeration housing 211 and the lower refrigeration housing 212 are fastened together, the sealing flexible member can seal the gap between the air inlet pipe and the air return pipe of the evaporator and the pipe outlet holes 219.

[0068] In this embodiment, during the installation and manufacturing process, the thermal insulation foam 270 can be first installed in the refrigeration lower housing 212, the ice-making evaporator 230 and the fan 240 can be installed in the refrigeration upper housing 211, and the water receiving tray 250 and other components can be installed in the refrigeration lower housing 212. Then, the refrigeration upper housing 211 and the refrigeration lower housing 212 are fastened together to form a pre-assembled module. Finally, the refrigeration housing 210 can be installed in the ice-making chamber 130. A sealing structure can be provided between the refrigeration upper housing 211 and the refrigeration lower housing 212.

[0069] When the ice-making chamber 130 is disposed in the freezing chamber 120 , after the housing 100 of the refrigeration appliance is manufactured, the refrigeration housing 210 of the pre-assembled ice-making refrigeration system 200 may be installed in the ice-making chamber 130 .

[0070] Specifically, the refrigeration upper housing 211 can be mounted to the mounting bracket 260 on the top wall of the ice making chamber 130. The refrigeration housing 210 can be slidably connected to the mounting bracket 260, and the sliding direction of the refrigeration housing 210 can be the extension direction of the drain nozzle 253 of the water receiving tray 250. A drain outlet can be provided on the side wall near the rear wall of the freezer compartment 120. The drain pipe 255 is embedded in the foam layer and can extend along the corner between the side wall and the rear wall. The foam layer at the corner is thicker, which has a better insulation effect. During the installation of the refrigeration housing 210, the drain nozzle 253 of the refrigeration housing 210 will not interfere with other components of the cabinet 100, facilitating installation.

[0071] The air inlet pipe of the ice-making evaporator 230 is then directly drawn along the rear wall of the freezer compartment 120 into the compressor compartment and welded thereto. The air return pipe of the ice-making evaporator 230 can be drawn along the rear wall of the freezer compartment 120 into the compressor compartment and welded thereto, or it can be directly drawn to the freezing evaporator 121 and welded thereto. When the air return pipe of the ice-making evaporator 230 is welded to the air inlet pipe of the freezing evaporator 121, part of the refrigerant from the compressor 150 can flow directly to the freezing evaporator 121 and then return to the compressor 150, while the other part can flow through the ice-making evaporator 230 to the freezing evaporator 121 and then return to the compressor 150, thereby improving the cooling capacity utilization rate.

[0072] After the inlet and return ducts of the ice-making evaporator 230 are welded, the air duct cover 160 and partition 140 of the freezer compartment 120 can be installed. The air duct and return ducts of the ice-making evaporator 230 can be placed between the air duct cover 160 and the wall of the freezer compartment 120. The distance between the air duct cover 160 and the refrigeration housing 210 can be greater than 18 mm to facilitate installation. The partition 140 directly separates the ice-making compartment 130 from the freezer compartment 120. This makes the overall installation process simple and quick, and the multiple components do not interfere with each other.

[0073] In this embodiment, the air outlet 217 and return air outlet 218 of the ice-making refrigeration system 200 may be oriented in different directions. The opening directions of the air outlet 217 and return air outlet 218 may form an angle, specifically a 90° angle. A gap may be left between a side wall of the ice-making refrigeration system 200 and a side wall of the ice-making chamber 130 to form an airflow path.

[0074] See also Figure 5 The refrigeration appliance further includes an air distributor 220, which at least partially divides the return air inlet 218 into a first return air inlet 2181 to form a first return air flow path and a second return air inlet 2182 to form a second return air flow path. The first return air inlet 2181 and the second return air inlet 2182 can be arranged side by side. The first return air inlet 2181 can be farther away from a side wall of the ice making chamber 130 than the second return air inlet 2182. The second return air flow path includes an air intake at least partially facing the air flow path.

[0075] In this embodiment, part of the cold air in the ice-making chamber enters the second return air path from the air intake port, and then returns to the interior of the refrigeration shell from the second return air port, so that the airflow is forced to flow through the air flow path between one side wall of the ice-making chamber 130 and the refrigeration shell, avoiding the existence of a dead zone in the air path between the side wall of the ice-making chamber 130 and the refrigeration shell.

[0076] In this embodiment, the area of the first return air outlet accounts for less than or equal to 80% of the total return air outlet area.

[0077] When the gap between a wall of the refrigeration housing and a side wall of the refrigeration compartment is small, the area of the second return air vent can be smaller than that of the first return air vent, allowing more cold air to flow through the airflow path therebetween. When the gap between a wall of the refrigeration housing and a side wall of the refrigeration compartment is larger, the area of the second return air vent can be larger than that of the first return air vent. This allows for better air circulation and reduces dead zones in the airflow path.

[0078] In this embodiment, the refrigeration housing 210 may include a first housing wall 213 and a second housing wall 214 disposed opposite each other. An air outlet 217 may be provided on the side of the first housing wall 213. A gap may be left between the second housing wall 214 and a side wall of the ice-making chamber 130 to form an airflow passage. Specifically, a gap may be left between the second housing wall 214 and the left side wall of the ice-making chamber 130 to form an airflow passage.

[0079] Specifically, in this embodiment, the refrigeration shell 210 may include a first shell wall 213 and a second shell wall 214 arranged opposite to each other in a first direction X, and a third shell wall 215 and a fourth shell wall 216 arranged opposite to each other in a second direction Y. The first direction X may be perpendicular to the second direction Y.

[0080] An air outlet 217 may be provided on the side of the first housing wall 213. Specifically, the first housing wall 213 may be located next to the ice maker 300, and the air outlet 217 may be directly provided on the first housing wall 213, next to the ice maker 300. Alternatively, an opening may be provided in the first housing wall 213 to connect to an air duct, with the air outlet 217 provided in the air duct.

[0081] A return air vent 218 may be provided on the side of the third housing wall 215. The opening direction of the return air vent 218 may be perpendicular to the opening direction of the air outlet 217. The return air vent 218 may be directly provided on the third housing wall 215, or an opening may be provided on the third housing wall 215 to connect to an air duct, which then provides the return air vent 218.

[0082] The first return air inlet 2181 and the second return air inlet 2182 are arranged in parallel along the first direction X. The first return air inlet 2181 is close to the first shell wall 213, and the second return air inlet 2182 is close to the second shell wall 214. The second return air flow path includes an air inlet at least partially facing the second shell wall 214. Figure 5 From the airflow diagram shown by the arrows, it can be understood that the air in the second return air flow path at least partially flows in from one side of the second shell 214 .

[0083] In this embodiment, the ice-making refrigeration system 200 and the ice-making machine 300 are arranged side by side, and the air outlet 217 is located on the side of the first housing wall 213, making it difficult for air to flow toward the second housing wall 214. Specifically, when the ice-making refrigeration system 200 is installed on the top of the ice-making chamber 130, the second housing wall 214 is adjacent to one side wall of the ice-making chamber 130, and a dead zone of airflow is easily formed between the second housing wall 214 and the side wall of the ice-making chamber 130. This can lead to uneven temperature within the ice-making chamber 130.

[0084] By setting up the air dividing portion 220, the return air outlet 218 is divided into a first return air outlet 2181 close to the first shell wall 213 and a second return air outlet 2182 close to the second shell wall 214, and two return air flow paths are formed. When the fan 240 is running, the fan 240 can force air to be sucked in from both the first return air flow path and the second return air flow path, so that part of the cold air in the ice making chamber 130 flows from the first shell wall 213 side to the return air outlet 218, and the other part flows from the second shell wall 214 side to the return air outlet 218.

[0085] In this way, the cold air in the ice making chamber 130 circulates from both sides of the ice making refrigeration system 200, avoiding the existence of dead zones in the air path in the ice making chamber 130. The temperature in the ice making chamber 130 is uniform, the cold air utilization rate is high, the cooling effect is good, and the ice making efficiency of the ice maker 300 is improved.

[0086] Furthermore, in this embodiment, a return air panel 223 is also provided in the ice making chamber 130, and a gap is left between the return air panel 223 and the third shell wall 215 to form a return air flow path. The air splitter 220 can be provided between the return air panel 223 and the third shell wall 215, and the air splitter 220 divides the return air flow path into a first return air flow path and a second return air flow path.

[0087] See also Figure 4 In a specific embodiment, a sealing panel 223 is provided at the opening of the ice-making chamber 130. The sealing panel 223 is partially opened to form a passageway into the ice-making chamber 130. An ice bank 350 is retractably mounted within the ice-making chamber 130, with the front panel of the ice bank 350 forming the ice-making door 131 of the ice-making chamber 130. Specifically, the ice bank 350 is mounted at the opening of the sealing panel 223. The front panel of the ice bank 350 may be provided with a sealing strip. When the ice bank 350 is closed, the sealing strip of the front panel of the ice bank 350 presses against the sealing panel, forming a seal. The sealing panel may directly form the return air panel 223. Specifically, a gap may be left between the sealing panel and the third housing wall 215 of the refrigeration housing 210 to form a return air flow path.

[0088] Of course, an independent return air panel may be additionally provided in the ice making chamber 130 to form a return air flow path between the panel and the third shell wall 215 .

[0089] During the cold air circulation process, the cold air in the ice-making refrigeration system 200 flows out from the air outlet 217 , passes through the return air flow path, and returns to the interior of the refrigeration housing 210 from the return air outlet 218 .

[0090] Further, in this embodiment, see Figure 8 The air dividing portion 220 includes a first air dividing rib 221 extending along a third direction and a second air dividing rib 222 extending from the end of the first air dividing rib 221 toward the second shell wall 214. The first air dividing rib 221 divides the return air outlet 218 into a first return air outlet 2181 and a second return air outlet 2182. The second air dividing rib 222 is located on the outside of the return air outlet 218, that is, completely outside the return air outlet 218, wherein the third direction is perpendicular to the first direction X and the second direction Y.

[0091] In this embodiment, the extension of the first wind rib 221 along the third direction can be that the extension direction of the first wind rib 221 completely coincides with the third direction, or the extension direction of the first wind rib 221 is slightly offset from the third direction, such as by about 10°, that is, the first wind rib 221 extends roughly along the third direction.

[0092] When the ice-making refrigeration system 200 is installed on the top wall of the ice-making chamber 130, the top wall of the refrigeration housing 210 is connected to the top wall of the ice-making chamber 130. During the cold air circulation process, almost no cold air flows between the top wall of the refrigeration housing 210 and the top wall of the ice-making chamber 130, or only a small amount of cold air flows between the top wall of the refrigeration housing 210 and the top wall of the ice-making chamber 130. Therefore, in this case, the second air distribution rib 222 can be disposed at the lower portion of the return air outlet 218, that is, the second air distribution rib 222 extends from the lower end of the first air distribution rib 221 toward the side of the second housing wall 214.

[0093] In this way, the second air distribution rib 222 can prevent the cold air from entering the second return air outlet 2182 from the lower end of the second return air outlet 2182. The second return air flow path is basically formed toward the air intake on the side of the second shell wall 214, thereby promoting more cold air to circulate back to the interior of the refrigeration shell 210 from the side of the second shell wall 214, thereby reducing the dead zone of the air path in the ice making chamber 130.

[0094] Of course, in other embodiments, the second air distribution rib 222 can also extend from the upper end of the first air distribution rib 221 to the second shell wall 214. For example, when other wind-shielding structures are provided at the lower part of the ice-making refrigeration system 200, cold air basically will not enter the second return air outlet 2182 from the lower part of the refrigeration shell 210. At this time, in order to encourage more cold air to circulate back to the interior of the refrigeration shell 210 from the side of the second shell wall 214, the second air distribution rib 222 can be set at the upper part of the second return air outlet 2182 to prevent cold air from entering the second return air outlet 2182 from the upper part of the second return air outlet 2182.

[0095] Of course, two second air distribution ribs 222 can also be provided, extending from the upper end of the first air distribution rib 221 and the lower end of the second air distribution rib 222 to one side of the second shell wall 214, respectively, to prevent cold air from returning to the interior of the refrigeration shell 210 from the upper and lower ends of the second return air outlet 2182.

[0096] Furthermore, in this embodiment, the second air dividing rib 222 includes a first air guiding section 2221 connected to the first air dividing rib 221 , and the first air guiding section 2221 is inclined relative to the first direction X in a direction away from the return air outlet 218 .

[0097] In this embodiment, when the second air distribution ribs 222 extend from the lower end of the first air distribution ribs 221 toward the second housing wall 214, the second air distribution ribs 222 can be tilted downward. When the second air distribution ribs 222 extend from the upper end of the first air distribution ribs 221 toward the second housing wall 214, the second air distribution ribs 222 can be tilted upward. The extension direction of the second air distribution ribs 222 can form an angle of 3°-5° with the second direction Y, thereby increasing the suction area of the second return air flow path.

[0098] Furthermore, in this embodiment, the second air dividing rib 222 also includes a second air guide section 2222, the second air guide section 2222 can be connected to the first air guide section 2221, the second air guide section 2222 can form the free end of the second air dividing rib 222, and the second air guide section 2222 can be inclined in the first direction X relative to the first air guide section 2221 away from the return air outlet 218.

[0099] In this embodiment, the second air guide section 2222 is further inclined relative to the first air guide section 2221 and can be an arc segment. This can prevent cold air from flowing in from the upper side or lower side of the second return air opening 2182 while increasing the air intake area of the second return air flow path, thereby facilitating cold air circulation.

[0100] Furthermore, in this embodiment, the return air inlet 218 is directly formed in the third housing wall 215, and the air splitter 220 is disposed in the third housing wall 215. The air splitter 220 can be integrally formed with the third housing wall 215. The height of the air splitter 220 along the second direction Y is greater than or equal to 10 mm, thereby forming an effective return air flow path. The distance between the third housing wall 215 and the return air panel 223 is greater than or equal to 7 mm, ensuring a return air gap and preventing insufficient return air volume, which could lead to frost on the surface of the return air inlet 218 and affect ice making efficiency.

[0101] Furthermore, in this embodiment, a gap is left between the air distribution portion 220 and the air return panel 223. Preferably, the distance between the air distribution portion 220 and the air return panel 223 is less than 7 mm.

[0102] It is understood that the distance between the first and second air distribution ribs 221, 222, and the return air panel 223 in the second direction Y is less than 7 mm. The micro-gap air duct formed between the air distribution portion 220 and the return air panel 223 improves air circulation within the ice making chamber 130, inhibits frost formation, and creates a frost-free space.

[0103] Furthermore, in this embodiment, the first direction X may be the width direction of the ice tray 320, and the second direction Y may be the length direction of the ice tray 320. The ice-making refrigeration system 200 and the ice maker 300 are disposed at the top of the ice-making chamber 130 and may be arranged side by side along the first direction X. The first direction X corresponds to the width direction of the ice-making chamber 130, i.e., the left-right direction; the second direction Y corresponds to the depth direction of the ice-making chamber 130, i.e., the front-back direction; and the third direction corresponds to the height direction of the ice-making chamber 130, i.e., the top-bottom direction. The fourth housing wall 216 of the refrigeration housing 210 may be opposite the rear wall of the ice-making chamber 130, and the third housing wall 215 may be located closer to the opening of the ice-making chamber 130. In other words, as viewed from the user facing the refrigerator, the third housing wall 215 is located in front of the fourth housing wall 216.

[0104] In this way, the space utilization rate in the ice-making chamber 130 can be improved, the volume inside the ice-making chamber 130 can be reduced, and the refrigeration effect and the ice-making efficiency of the ice-making machine 300 can be improved.

[0105] In this embodiment, the ice-making evaporator 230 and the fan 240 can be arranged along the second direction Y, and the ice-making evaporator 230 can be arranged on the side close to the return air port 218. In this way, the cold air enters the refrigeration shell 210 through the return air port 218 and can pass through the ice-making evaporator 230, exchange heat with the ice-making evaporator 230, and then flow out from the air outlet 217, so the refrigeration efficiency is relatively high.

[0106] The ratio of the area of the surface of the ice-making evaporator 230 facing the return air inlet 218 to the area of the return air inlet 218 may be 0.8-2.5.

[0107] The ice-making evaporator 230 has a width W in the first direction X, a length L in the second direction Y, and a height H in the third direction. The area of the surface of the ice-making evaporator 230 facing the return air port 218 can be W*H. The area of the return air port 218 can be the sum of the area of the first return air port 2181 and the area of the second return air port 2182.

[0108] Such a setting can ensure that the air volume and wind speed entering the refrigeration shell 210 from the return air port 218 meet the needs of the ice-making evaporator 230, improve the cold capacity utilization rate of the ice-making evaporator 230, reduce frost on the surface of the ice-making evaporator 230, improve the refrigeration effect of the ice-making chamber 130, and speed up the ice-making speed.

[0109] Furthermore, in this embodiment, in the second direction Y, the distance between the return air outlet 218 and the ice-making evaporator 230 is greater than 5 mm. In this way, the frost holding space can be increased, the frost on the surface of the ice-making evaporator 230 can be further reduced, the cooling effect of the ice-making chamber 130 can be improved, and the ice-making speed can be accelerated.

[0110] In the third direction, the distance between the end of the return air vent 218 and the end of the evaporator is greater than 3 mm. The upper end of the return air vent 218 can be 6-10 mm away from the upper end of the ice-making evaporator 230, or the lower end of the return air vent 218 can be 6-10 mm away from the lower end of the ice-making evaporator 230. Alternatively, the upper and lower ends of the return air vent 218 can be 6-10 mm away from the upper and lower ends of the evaporator, respectively.

[0111] In this way, the return air inlet 218 can be ensured to be located as close as possible to the middle of the ice-making evaporator 230, and the cold air entering the refrigeration shell 210 from the return air inlet 218 can basically all pass through the middle of the ice-making evaporator 230. In this way, the frost can be condensed in the large space of the ice-making evaporator 230 as much as possible to avoid frost overflow.

[0112] In the second direction Y, the distance between the evaporator and the air outlet 217 of the fan 240 is approximately 30-40 mm, thereby reducing the possibility of frost on the air outlet 217 of the fan 240.

[0113] The ratio of the area of the return air port 218 to the area of the air outlet 217 is 1.1-3, that is, the area of the return air port is larger than the area of the air outlet, which can improve the utilization rate of cold air and reduce frosting.

[0114] By setting as above, the module of ice-making refrigeration system 200 can be minimized, thereby minimizing the ice-making chamber 130, thereby greatly improving the utilization rate of cooling capacity, reducing energy consumption, and increasing the ice-making speed.

[0115] Furthermore, in this embodiment, a gap is provided between the air outlet 217 and the ice maker 300. Specifically, a gap is provided between the first housing wall 213 of the refrigeration housing 210 and the ice maker 300. This allows for an air guide channel to be formed between the refrigeration housing 210 and the ice maker 300. A portion of the air blown out from the air outlet 217 flows directly downward through the gap between the air outlet 217 and the ice maker 300, facilitating uniform cooling within the ice-making chamber 130. This also facilitates providing cooling to the ice storage bin 350 below the ice maker 300, preventing the ice inside the bin 350 from melting.

[0116] Furthermore, in this embodiment, the ice maker 300 includes an ice making bracket 310 and an ice tray 320 mounted within the ice making bracket 310. The ice making bracket 310 may include a first side 311 and a second side 312. The first side 311 and the second side 312 may be disposed opposite each other and may extend along the second direction Y. The air outlet 217 may be disposed adjacent to the ice making bracket 310. Specifically, the ice making bracket 310 may be disposed adjacent to the ice making refrigeration system 200, with the first side 311 of the ice making bracket 310 adjacent to the first housing wall 213 of the refrigeration housing 210. The first side 311 of the ice making bracket 310 may be disposed adjacent to the first housing wall 213, and the air outlet 217 may be disposed adjacent to the first side 311.

[0117] In this embodiment, see Figure 14 The first side 311 of the ice-making bracket 310 may be provided with a bracket air inlet 330 , and the second side 312 may be provided with a bracket air outlet 340 .

[0118] The bracket air inlet 330 may include a horizontal air inlet 331. The area of the horizontal air inlet 331 may be larger than the area of the bracket air outlet 340. Specifically, the area ratio of the horizontal air inlet 331 to the bracket air outlet 340 may be 1.1-3. The height difference between the horizontal air inlet 331 and the bracket air outlet 340 may be within 50 mm. Cold air flowing out of the air outlet 217 of the refrigeration housing 210 may enter the interior of the ice-making bracket through the horizontal air inlet 331 and flow out through the bracket air outlet 340.

[0119] The cold air entering through the horizontal air inlet 331 flows primarily above the ice tray 320. By setting the area of the bracket air outlet 340 smaller than that of the horizontal air inlet 331, the cold air is retained above the ice tray 320. Furthermore, the second side 312 of the ice-making bracket 310 acts as a rebate for the cold air entering through the horizontal air inlet 331, thereby creating an internal vortex within the ice tray and increasing the ice-making rate.

[0120] Furthermore, in this embodiment, the bracket air inlet 330 may further include an ice surface air inlet 332. The ice surface air inlet 332 may be tilted toward the ice tray 320, thereby directing cold air into the ice tray 320. During ice making, the ice compartments of the ice tray 320 are filled with water. The cold air entering through the ice surface air inlet 332 can be directed directly toward the water surface in the ice tray 320, accelerating the cooling of the water surface and increasing the ice making rate.

[0121] The area of the ice surface air inlet 332 is smaller than that of the horizontal air inlet 331. The ice surface air inlet 332 and the horizontal air inlet 331 can be arranged one above the other. The area ratio of the horizontal air inlet 331 to the ice surface air inlet 332 can be 1.1-3. Preferably, the area of the ice surface air inlet 332 can be half the area of the horizontal air inlet 331. The ice surface air inlet 332 can be tilted at an angle of 22°-30° relative to the first direction X, ensuring that the cold air is blown toward the water or ice surface without excessive cooling, thereby preventing wrinkles on the ice surface caused by excessive cooling.

[0122] Furthermore, in this embodiment, the bracket air inlet of the ice maker 300 also includes an end air inlet 333 arranged at the end of the ice making bracket 310 along the second direction Y. The end air inlet 333 can be tilted toward the two ends of the ice maker 300 bracket, thereby guiding the cold air entering from the end air inlet 333 to the end of the ice making bracket 310.

[0123] In this embodiment, the ice-making bracket 310 may further include a third side 313 and a fourth side 314 that are opposite to each other. The third side 313 and the fourth side 314 may connect the first side 311 and the second side 312 and may extend along the first direction X. The third side 313 may be located on one side of the third housing wall 215 of the refrigeration housing 210, and the fourth side 314 may be located on one side of the fourth housing wall 216 of the refrigeration housing 210. The drive assembly may be mounted on the fourth side 314 of the ice-making bracket 310.

[0124] In this embodiment, the end air inlet 333 can be disposed at an end of the ice-making bracket 310 close to the fourth side 314 and / or an end of the ice-making bracket 310 close to the third side 313. The end air inlet 333 disposed at the end of the ice-making bracket 310 close to the fourth side 314 can be tilted toward the fourth side 314, and the end air inlet 333 disposed at the end of the ice-making bracket 310 close to the third side 313 can be tilted toward the third side 313. The angle between the end air inlet 333 and the first direction X can be greater than 45°.

[0125] When the cold air from the return air vent 218 enters the ice-making rack 310, a dead zone easily forms at the end of the rack 310. The ice cube trays near the end receive less cold air and are less likely to freeze, which can lead to the ice cube trays not being fully frozen at the end of the ice-making process. Therefore, tilting the end air inlet 333 directs more air toward the end ice cube trays, increasing the amount of cold air supplied to them.

[0126] In a specific embodiment, the return air port 218 of the refrigeration housing 210 may be relatively close to the side of the fourth housing wall 216. The fan 240 includes a fan housing, and the air outlet 217 of the fan housing may be inclined relative to the first direction X toward the third side 313 of the ice-making bracket 310. In this way, during the cold air circulation process, the cold air blown out of the refrigeration housing 210 is directed toward the third side 313 of the ice-making bracket 310. As a result, a dead zone in the air path may occur on the fourth side 314 of the ice-making bracket 310. Therefore, an end air inlet 333 inclined toward the fourth side 314 may be provided near one end of the fourth side 314 of the ice-making bracket 310 to guide the cold air to the end of the fourth side 314, thereby ensuring that the ice tray 320 receives the most uniform cooling.

[0127] In summary, a multi-dimensional three-dimensional surrounding air path can be formed in the ice-making chamber 130, the temperature in the ice-making chamber 130 is uniform, the cold air utilization rate is high, and the ice-making speed is fast.

[0128] See also Figure 15 , which is a refrigeration appliance according to the second embodiment of the present invention.

[0129] The refrigeration appliance of this embodiment differs from the refrigeration appliance of the first embodiment mainly in the structure of the ice-making refrigeration system 200 .

[0130] In this embodiment, the ice-making refrigeration system 200 includes a refrigeration housing 210 , which is installed in the ice-making chamber 130 . The refrigeration housing 210 and a side wall of the ice-making chamber 130 together enclose an ice-making evaporator chamber.

[0131] The ice-making evaporator 230 can be directly installed in the ice-making chamber 130, and the fan 240 and the water receiving tray 250 can be pre-installed in the refrigeration shell 210 to form a refrigeration shell module. After the ice-making evaporator 230 is installed, the pre-installed refrigeration shell module is connected to a wall of the ice-making chamber 130, and the ice-making evaporator 230 is accommodated inside the ice-making evaporator shell 310.

[0132] In a specific embodiment, the ice-making refrigeration system 200 can be mounted on the top wall of the ice-making chamber 130. A mounting bracket 260 can be provided at the top of the ice-making chamber. The mounting bracket 260 can be partially embedded in the foam layer of the housing 100, with the top wall of the ice-making chamber 130 partially extending into the interior of the ice-making chamber. During installation, the ice-making evaporator 230 can be connected to the mounting bracket 260. The ice-making evaporator's air inlet and return pipes are welded to the rest of the refrigeration system. Finally, the preassembled refrigeration housing module is connected to the mounting bracket 260. At this point, the refrigeration housing 210 is sealed against the top wall of the ice-making chamber 130, and together they enclose the ice-making evaporator chamber.

[0133] In this embodiment, an air splitting portion 220 is provided at the return air port 218 , wherein the structure of the air splitting portion 220 may be substantially the same as that of the first embodiment.
