[0042] The refrigeration appliance may have a refrigeration compartment. The refrigeration appliance may include a housing 100, a storage compartment may be formed in the housing 100, the storage compartment may include a refrigerating compartment 110, a freezing compartment 120, and the storage compartment may also include a temperature-changing chamber. The refrigeration appliance may also include an ice-making compartment 130, and an ice-making machine 300 may be installed in the ice-making compartment 130. An ice storage box 350 may be installed in the ice-making compartment 130, and the ice storage box 350 may be placed under the ice-making machine 300, and the user may take the ice storage box 350 out of the ice-making compartment 130. The refrigeration compartment may include a storage compartment or the ice-making compartment 130.

[0043] A compressor compartment may also be provided on the side of the housing 100, and a compressor 150 may be installed in the compressor compartment. 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. For example, the storage evaporator may be used to provide cold air to the freezing compartment and / or the variable temperature compartment, and may also supply cold air to the refrigerating compartment.

[0044] Specifically, the storage evaporator may include a refrigeration evaporator 111 for supplying cold air to the refrigeration chamber 110 and a freezing evaporator 121 for supplying cold air to the freezing chamber 120. The storage evaporator and the ice-making evaporator 230 may share a compressor 150. By using an independent ice-making evaporator 230 to supply cold air to the ice-making chamber 130, it is possible to ensure that the cold air in the ice-making chamber 130 is clean and is not affected by the smell of the food stored in the storage room, so that clean ice cubes can be made.

[0045] In one embodiment of the utility model, the ice making chamber 130 is arranged in the freezing chamber 120, and the cold air is isolated between the ice making chamber 130 and the freezing chamber 120. The refrigeration appliance includes a freezing door 122 for opening and closing the freezing chamber 120, and the ice making chamber 130 is closed when the freezing door 122 is closed. When the user needs to take out the ice storage box 350 and other components in the ice making chamber 130, the freezing door 122 needs to be opened first.

[0046] In this embodiment, the refrigeration appliance may further include an ice-making door 131, which may be used to open and close the ice-making chamber 130. The ice-making door 131 may be integrally arranged with the ice storage box 350, such as the ice storage box 350 may be pulled out and arranged in the ice-making chamber 130, and the front panel of the ice storage box 350 may form the ice-making door 131. When the freezer door 122 is closed, the ice-making door 131 may be in a closed state, and the freezer door 122 covers the ice-making door 131. When the user needs to open the ice-making door 131, the freezer door 122 needs to be opened first.

[0047] The box body 100 may include an outer shell and an inner liner, and 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 foaming material. The outer shell and the inner liner may be foamed 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 120 to directly separate the ice making chamber 130. The partition 140 may be a heat-insulating partition. In this embodiment, the ice making chamber 130 may be a space enclosed by the inner liner and the partition 140, and other partitions may be installed in the ice making chamber 130 to separate the ice making chamber, such as a partition that may be installed to separate the air duct in the ice making chamber or a compartment for installing components such as an evaporator. The partition 140 is sealed with the side wall of the freezer 120, such as by a sealing strip or other structures to achieve sealing, so as to avoid the exchange of cold air between the ice making chamber 130 and the freezer 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 a top wall and side walls of the freezing chamber 120 .

[0048] Of course, the storage compartment may further include a variable temperature chamber, and the storage evaporator may further include a variable temperature evaporator for supplying cold air to the variable temperature chamber. The ice making chamber 130 may also be arranged in the variable temperature chamber and be isolated from the cold air 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 closed, and the user needs to open the variable temperature door to enter the ice making chamber 130. The method of arranging the ice making chamber 130 in the variable temperature chamber may be substantially the same as the method of arranging the ice making chamber 130 in the freezing chamber 120.

[0049] In one embodiment of the utility model, a 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.

[0050] 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 , and the ice-making refrigeration system includes an ice-making evaporator 230 .

[0051] For details, see Figures 5 to 13, which is a refrigeration appliance of the first embodiment of the utility model. In this embodiment, the ice-making evaporator 230 is installed inside the ice-making chamber 130. The refrigeration appliance includes an ice-making refrigeration system 200, and the ice-making refrigeration system 200 may include a refrigeration housing 210 and an ice-making evaporator 230, and the ice-making evaporator 230 is placed inside the refrigeration housing 210. The ice-making refrigeration system 200 may also include a fan 240, a water receiving tray 250, and a defrosting heating wire, which can all be placed inside the refrigeration housing 210. The water receiving tray 250 can be placed below the ice-making evaporator 230. When the ice-making evaporator 230 needs to be defrosted, the defrosting heating wire can be started for heating, and the water formed by the frost melting on the surface of the ice-making evaporator 230 can flow into the water receiving tray 250.

[0052] 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 heat insulation layer of the box body 100, and the drain nozzle 253 of the water receiving tray 250 may be inserted into the drain port, that is, one end of the drain pipe is connected to the drain port, and the other end may extend into the press chamber, and the drain pipe may be at least partially buried in the foaming layer at the corner of the side wall of the box body. 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.

[0053] The ice-making refrigeration system 200 may have an air outlet 217 and an air return port 218. The cold energy of the ice-making refrigeration system 200 is directly transmitted to the ice-making chamber 130 through the air outlet 217, and the cold energy loss is small, which can greatly improve the ice-making efficiency. The air outlet 217 can be set on the wall of the refrigeration housing 210 opposite to the ice-making machine, so that the air blown out of the air outlet 217 can be blown directly to the ice-making machine.

[0054] The air outlet 217 and the air return 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 melting of ice cubes in the ice storage box 350 during the defrosting process of the ice-making evaporator 230 can be reduced.

[0055] 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 may include the left side, right side, front side and rear side of the ice-making machine 300.

[0056] 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.

[0057] Specifically, the ice-making refrigeration system 200 and the ice-making machine 300 can be arranged in parallel along the width direction of the ice-making chamber 130, so as to maximize the space utilization of the ice-making chamber 130, reduce the volume inside the ice-making chamber 130, and improve the refrigeration efficiency. The pressure inside the ice-making chamber 130 can be always higher than the pressure inside the freezing chamber 120. When the ice-making chamber 130 and the freezing chamber 120 are separated by a partition plate 140, it can be prevented that the odor in the freezing chamber 120 enters the ice-making chamber 130 through the gap between the partition plate 140 and the inner liner of the box body 100, and contaminates the ice cubes in the ice-making chamber 130.

[0058] In this embodiment, see Figure 7-Figure 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 may be installed 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 buckled to form an ice-making evaporator chamber. The fan 240, the water receiving tray 250 and the defrosting heating wire can all be placed in the ice-making evaporator chamber.

[0059] The ice-making evaporator 230 and the fan 240 can be installed in the refrigeration upper housing 211, and the water tray 250 can be installed in the refrigeration lower housing 212. The fan 240 can be detachably installed in the refrigeration upper housing 211. During the installation process, the pre-installed module can be directly installed, and the installation process is convenient. If a fault occurs during use, the refrigeration lower housing 212 can be directly removed for maintenance.

[0060] See also Fig.10 and Fig.12 The refrigeration upper housing 211 may be provided with a fan installation slot 241, and the fan 240 may be installed in the fan installation slot 241 by buckling. The fan installation slot 241 may include a side wall and a top wall, and the side wall and the top wall of the fan installation slot 241 may be provided with a shock-absorbing spring. When the fan 240 is fixed to the refrigeration upper housing 211 by buckling, the shock-absorbing spring can increase elasticity and reduce the hard connection between the fan 240 and the refrigeration upper housing 211, thereby reducing vibration and noise during the operation of the fan 240.

[0061] The fan 240 may have a fan housing, and the fan housing may form an air outlet duct of the fan 240. The refrigeration upper housing 211 may also be provided with a mounting groove that matches the air outlet duct of the fan 240, and 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.

[0062] The fan 240 can be installed on the refrigeration upper housing 211 at an angle relative to the horizontal plane, that is, 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. The water receiving tray 250 can be arranged below the fan 240, so that the water in the fan housing can flow out from the air outlet of the fan 240 to the water receiving tray 250 to be discharged, so as to avoid freezing inside the fan 240 and affecting the refrigeration.

[0063] The defrosting heating wire inside the ice-making refrigeration system 200 can be integrated inside the ice-making evaporator 230. The ice-making evaporator 230 can include fins and refrigerant pipes, and the refrigerant pipes can pass through the fins and be fixed by the fins. The fins can also be provided with holes for installing the defrosting heating wires, and the defrosting heating wires can also pass through the fins and be fixed by the fins. Aluminum plates 231 can also be provided at both ends of the ice-making evaporator 230, and the aluminum plates 231 can protect the defrosting heating wires and prevent the defrosting heating wires from being scratched. The ice-making evaporator 230 can be installed tilted to facilitate the discharge of defrosting water in the ice-making evaporator 230.

[0064] See also Fig. 9 and Fig.13 The 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 the upper and lower surfaces of the first water receiving portion 251 may be wavy.

[0065] A wind shield 254 may be provided between the ice-making evaporator 230 and the water receiving tray 250. The wind shield 254 may be fixed to the ice-making evaporator 230 and abut the water receiving tray 250, or may be fixed to the water receiving tray 250 and abut the ice-making evaporator 230. The wind shield 254 may reduce the cold air flowing through the bottom of the ice-making evaporator 230 during the return air process, thereby improving the refrigeration efficiency. In addition, the wind shield 254 may be a heat-conducting structure, so that the wind shield 254 may transfer the heat of the defrosting heating wire to the water receiving tray 250 to prevent the water in the water receiving tray 250 from freezing. In addition, part of the cold air returning to the interior of the refrigeration housing 210 during the return air process flows through the water receiving tray 250. Since the temperature of the cold air returning to the interior of the refrigeration housing 210 is higher than the temperature of the cold air in the ice-making chamber 130, the temperature of the bottom surface of the refrigeration housing 210 may be increased, so that the temperature inside the refrigeration housing 210 is higher than that inside the ice-making chamber 130.

[0066] At the same time, the wavy water receiving tray 250 can also reduce heat transfer to the outside, so the temperature difference between the inside of the refrigeration housing 210 and the ice making chamber 130 will not be too large. Therefore, a thinner insulation structure can be used to ensure that there is no frost inside the refrigeration housing 210. Specifically, the refrigeration housing 210 can also be provided with an insulation foam 270, which can be 5mm EPS foam with a density of 30-40kg / m3.

[0067] The second water receiving portion 252 of the water receiving tray 250 may be a planar structure, thereby increasing the distance between the second water receiving portion 252 and the fan 240 and providing air suction space for the fan 240. The second water receiving portion 252 of the water receiving tray 250 may be provided with a drain nozzle, and the second water receiving portion 252 may be provided with an aluminum foil heating element, which may extend into the drain nozzle 253 to prevent the drain nozzle 253 and the corresponding drain port of the box 100 from freezing during the draining process, thereby ensuring the smooth discharge of defrosted water. The planar structure of the second water receiving portion 252 is also convenient for laying the aluminum foil heating element.

[0068] The refrigeration upper shell 211 and the refrigeration lower shell 212 may be provided with mutually matching outlet holes 219, and the air inlet pipe and the air return pipe of the ice-making evaporator 230 may pass through the outlet holes 219. The air inlet pipe and the air return pipe of the ice-making evaporator 230 may be covered with a sealing flexible member, which may be foam. When the refrigeration upper shell 211 and the refrigeration lower shell 212 are buckled together, the gap between the air inlet pipe, the air return pipe and the outlet hole 219 of the evaporator can be sealed by the sealing flexible member.

[0069] In this embodiment, during the installation and manufacturing process, the thermal insulation foam 270 can be first installed in the refrigeration lower shell 212, the ice-making evaporator 230 and the fan 240 can be installed in the refrigeration upper shell 211, and the water receiving tray 250 and other components can be installed in the refrigeration lower shell 212. Then, the refrigeration upper shell 211 and the refrigeration lower shell 212 are buckled together to form a pre-assembled module, and finally, the refrigeration shell 210 can be installed in the ice-making chamber 130. A sealing structure can be provided between the refrigeration upper shell 211 and the refrigeration lower shell 212.

[0070] 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-installed ice-making refrigeration system 200 may be installed in the ice-making chamber 130 .

[0071] Specifically, the refrigeration upper shell 211 can be installed on the mounting bracket 260 of the top wall of the ice making chamber 130. The refrigeration shell 210 can be slidably connected to the mounting bracket 260, and the sliding direction of the refrigeration shell 210 can be the extension direction of the drain nozzle 253 of the water receiving tray 250. A drain port can be provided near the rear wall of the side wall of the freezing chamber 120, and the drain pipe 255 is buried in the foam layer and can extend along the corner of the side wall and the rear wall. The foam layer at the corner is thicker and has a better insulation effect. In addition, during the installation of the refrigeration shell 210, the drain nozzle 253 of the refrigeration shell 210 will not interfere with other components of the box 100, which is convenient for installation.

[0072] Then the air inlet pipe of the ice-making evaporator 230 is directly pulled along the rear wall of the freezing chamber 120 to the compressor compartment for welding, and the air return pipe of the ice-making evaporator 230 can be pulled along the rear wall of the freezing chamber 120 to the compressor compartment for welding, or can be directly pulled to the freezing evaporator 121 and welded to the air inlet pipe of the freezing evaporator 121. 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, and the other part can flow to the freezing evaporator 121 after passing through the ice-making evaporator 230 and then return to the compressor 150, thereby improving the utilization rate of cooling capacity.

[0073] After the air inlet and return pipes of the ice-making evaporator 230 are welded, the air duct cover 160 and the partition baffle 140 of the freezing chamber 120 can be installed. The air inlet and return pipes of the ice-making evaporator 230 can be placed between the air duct cover 160 and the wall of the freezing chamber 120. The distance between the air duct cover 160 and the refrigeration housing 210 can be greater than 18 mm to facilitate installation by workers. The partition baffle 140 directly separates the ice-making chamber 130 in the freezing chamber 120. In this way, the overall installation process is simple and quick. Multiple components will not interfere with each other.

[0074] In this embodiment, the air outlet 217 of the ice-making refrigeration system 200 may be disposed beside the ice-making machine 300. The air outlet 217 and the air return port 218 of the ice-making refrigeration system 200 may have different directions.

[0075] In this embodiment, the refrigeration housing 210 may include a first housing wall 213 and a second housing wall 214 disposed opposite to each other in a first direction X, and a third housing wall 215 and a fourth housing wall 216 disposed opposite to each other in a second direction Y. The first direction X may be perpendicular to the second direction Y.

[0076] The first housing wall 213 may be provided with an air outlet 217, that is, the air outlet 217 may be provided at one side of the first housing wall 213. Specifically, the first housing wall 213 may be located beside the ice maker 300, and the air outlet 217 may be directly opened in the first housing wall 213, and the air outlet 217 may be located beside the ice maker 300. Of course, an opening may also be opened at the first housing wall 213 to connect to an air duct, and the air duct may be provided with an air outlet 217.

[0077] A return air port 218 may be provided on the side of the third shell wall 215. The opening direction of the return air port 218 may be perpendicular to the opening direction of the air outlet 217. The return air port 218 may be directly opened on the third shell wall 215, or an opening may be opened at the third shell wall 215 to connect to an air duct, and the air duct may open the return air port 218.

[0078] See also Figure 5The refrigeration appliance further includes an air dividing portion 220, which at least partially divides the return air port 218 into a first return air port 2181 to form a first return air flow path and a second return air port 2182 to form a second return air flow path. The first return air port 2181 and the second return air port 2182 are arranged in parallel along the first direction X. The first return air port 2181 is close to one side of the first shell wall 213, and the second return air port 2182 is close to one side of the second shell wall 214. The second return air flow path includes an air inlet at least partially facing one side of the second shell wall 214. Figure 5 From the airflow diagram shown by the arrows, it can be understood that the wind of the second return air flow path at least partially flows in from one side of the second shell 214.

[0079] In this embodiment, the ice-making refrigeration system 200 and the ice-making machine 300 are arranged in parallel, and the air outlet 217 is arranged on the side of the first shell wall 213, so that the airflow is not easy to flow to the side of the second shell wall 214. Specifically, when the ice-making refrigeration system 200 is installed on the top of the ice-making chamber 130, the second shell wall 214 is adjacent to a side wall of the ice-making chamber 130, and an airflow dead zone is easily formed between the second shell wall 214 and the side wall of the ice-making chamber 130. As a result, the temperature in the ice-making chamber 130 is uneven.

[0080] By setting 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 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 to the return air outlet 218, and the other part flows from the second shell wall 214 to the return air outlet 218.

[0081] In this way, the cold air in the ice making room 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 room 130. The temperature in the ice making room 130 is uniform, the cold air utilization rate is high, the refrigeration effect is good, and the ice making efficiency of the ice maker 300 is improved.

[0082] Furthermore, in this embodiment, the first return air outlet 2181 is close to the first shell wall 213 , the second return air outlet 2182 is close to the second shell wall 214 , and the area of ​​the first return air outlet 2181 is smaller than that of the second return air outlet 2182 .

[0083] In this embodiment, the area ratio of the first return air port 2181 to the second return air port 2182 is 1:2-2:3. Since the air outlet 217 of the ice-making refrigeration system 200 is arranged on the side of the first shell wall 213, there is more cold air on the side of the first shell wall 213. During the air return process, the cold air will preferentially return to the inside of the refrigeration shell 210 from the side of the return air port 218 close to the first shell wall 213. When the return air port 218 is divided into two parallel return air ports along the first direction X, the cold air will preferentially return to the inside of the refrigeration shell 210 from the first return air port 2181.

[0084] Therefore, setting the area of ​​the first return air port 2181 to be smaller than the area of ​​the second return air port 2182 can reduce the amount of cold air returning to the interior of the refrigeration shell 210 from the first return air port 2181 and increase the amount of cold air returning to the interior of the refrigeration shell 210 from the second return air port 2182, thereby further balancing the cold air in the ice making chamber 130.

[0085] Furthermore, in the present 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.

[0086] See also Figure 4 In a specific embodiment, a sealing panel 223 is provided at the opening of the ice making chamber 130, and a portion of the sealing panel 223 is opened to form a passage into the ice making chamber 130. The ice storage box 350 can be installed in the ice making chamber 130 in a retractable manner, and the front panel of the ice storage box 350 forms the ice making door 131 of the ice making chamber 130. Specifically, the ice storage box 350 is installed at the opening of the sealing panel 223. The front panel of the ice storage box 350 can be provided with a sealing strip, and when the ice storage box 350 is closed, the sealing strip of the front panel of the ice storage box 350 can be pressed against the sealing panel to form a seal. The sealing panel can directly form the return air panel 223, that is, a gap can be left between the sealing panel and the third shell wall 215 of the refrigeration shell 210 to form a return air flow path.

[0087] 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 .

[0088] 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 .

[0089] Further, in this embodiment, see Figure 8The 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 outer side of the return air outlet 218, wherein the third direction is perpendicular to the first direction X and the second direction Y.

[0090] 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 offset by about 10°, that is, the first wind rib 221 extends approximately along the third direction.

[0091] 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, basically no cold air will flow 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 will flow between the top wall of the refrigeration housing 210 and the top wall of the ice-making chamber 130. Therefore, at this time, the second air distribution rib 222 can be set at the lower part of the return air port 218, that is, the second air distribution rib 222 extends from the lower end of the first air distribution rib 221 to one side of the second housing wall 214.

[0092] In this way, the second air dividing rib 222 can prevent 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 port 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.

[0093] Of course, in other embodiments, the second air dividing rib 222 may also extend from the upper end of the first air dividing rib 221 to the second shell wall 214. For example, when other wind shielding structures are provided at the lower portion of the ice-making refrigeration system 200, cold air will basically not enter the second return air outlet 2182 from the lower portion 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 dividing rib 222 may be provided at the upper portion of the second return air outlet 2182 to prevent cold air from entering the second return air outlet 2182 from the upper portion of the second return air outlet 2182.

[0094] Of course, two second air dividing ribs 222 can also be provided, extending from the upper end of the first air dividing rib 221 and the lower end of the second air dividing 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.

[0095] Furthermore, in the present 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 .

[0096] In this embodiment, when the second air dividing rib 222 extends from the lower end of the first air dividing rib 221 to the side of the second shell wall 214, the second air dividing rib 222 can be tilted downward, and when the second air dividing rib 222 extends from the upper end of the first air dividing rib 221 to the side of the second shell wall 214, the second air dividing rib 222 can be tilted upward. The extension direction of the second air dividing rib 222 can form an angle of 3°-5° with the second direction Y, thereby increasing the air suction area of ​​the second return air flow path.

[0097] Furthermore, in this embodiment, the second air dividing rib 222 also includes a second air guiding segment 2222, and the second air guiding segment 2222 can be connected to the first air guiding segment 2221, and the second air guiding segment 2222 can form a free end of the second air dividing rib 222, and the second air guiding segment 2222 can be inclined in the first direction X relative to the first air guiding segment 2221 away from the return air outlet 218.

[0098] In this embodiment, the second air guide section 2222 is further inclined relative to the first air guide section 2221, and the second air guide section 2222 may be an arc section. In this way, the air suction area of ​​the second return air flow path can be increased while preventing cold air from flowing in from the upper side or the lower side of the second return air port 2182, which is beneficial to the circulation of cold air.

[0099] Furthermore, in this embodiment, the return air port 218 is directly opened on the third shell wall 215, and the air splitter 220 is arranged on the third shell wall 215. The air splitter 220 can be integrally formed with the third shell wall 215. The height of the air splitter 220 along the second direction Y is greater than or equal to 10 mm, so that an effective return air flow path can be formed. The distance between the third shell wall 215 and the return air panel 223 is greater than or equal to 15 mm, so as to ensure the return air gap, avoid too small return air volume, and avoid frost on the surface of the return air port 218, which affects the ice making efficiency.

[0100] Further, in this embodiment, a gap is left between the air splitter 220 and the air return panel 223. Preferably, the distance between the air splitter 220 and the air return panel 223 is 2-3 mm.

[0101] It can be understood that the distance between the first air distribution rib 221 and the second air distribution rib 222 and the return air panel 223 is 2-3 mm in the second direction Y. A micro-gap air duct is formed between the air distribution part 220 and the return air panel 223, which can improve the air circulation in the ice making chamber 130, inhibit frost formation, and form a frost-free space.

[0102] Further, in the present embodiment, the first direction X may be the width direction of the ice tray 320, 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 arranged at the top of the ice-making chamber 130, and they may be arranged in parallel along the first direction X, wherein the first direction X is consistent with the width direction of the ice-making chamber 130, i.e., the left-right direction, the second direction Y is consistent with the depth direction of the ice-making chamber 130, i.e., the front-back direction, and the third direction is consistent with the height direction of the ice-making chamber 130, i.e., the up-down direction. The fourth housing wall 216 of the refrigeration housing 210 may be opposite to the rear wall of the ice-making chamber 130, and the third housing wall 215 is close to the opening side of the ice-making chamber 130, i.e., with reference to when the user faces the refrigerator, the third housing wall 215 is placed in front of the fourth housing wall 216.

[0103] 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.

[0104] 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. After heat exchange with the ice-making evaporator 230, it flows out from the air outlet 217, and the refrigeration efficiency is relatively high.

[0105] The ratio of the area of ​​the surface of the ice-making evaporator 230 facing the return air port 218 to the area of ​​the return air port 218 may be 1-2.5.

[0106] 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 ice-making evaporator 230 facing the return air port 218 may be W*H. The area of ​​the return air port 218 may be the sum of the area of ​​the first return air port 2181 and the area of ​​the second return air port 2182.

[0107] Such a configuration 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.

[0108] Furthermore, in this embodiment, in the second direction Y, the distance between the return air port 218 and the ice-making evaporator 230 is 15-20 mm. In this way, the frost holding space can be increased, and the frost on the surface of the ice-making evaporator 230 can be further reduced, thereby improving the cooling effect of the ice-making chamber 130 and accelerating the ice-making speed.

[0109] In the third direction, the end of the return air port 218 is 6-10 mm away from the end of the evaporator. The upper end of the return air port 218 may be 6-10 mm away from the upper end of the ice-making evaporator 230, or the lower end of the return air port 218 may be 6-10 mm away from the lower end of the ice-making evaporator 230. Of course, the upper and lower ends of the return air port 218 may be 6-10 mm away from the upper and lower ends of the evaporator, respectively.

[0110] In this way, the return air inlet 218 can 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, frost can be condensed in the large space of the ice-making evaporator 230 as much as possible to avoid frost overflow.

[0111] 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.

[0112] The ratio of the area of ​​the return air port 218 to the area of ​​the air outlet 217 is 1.5-2, 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.

[0113] By configuring as above, the module of the 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.

[0114] Furthermore, in the present embodiment, a gap is left between the air outlet 217 and the ice maker 300. Specifically, a gap is left between the first housing wall 213 of the refrigeration housing 210 and the ice maker 300, so that an air guide channel can be formed between the refrigeration housing 210 and the ice maker 300, and part of the wind blown out from the air outlet 217 will directly flow down from the gap between the air outlet 217 and the ice maker 300, which is beneficial to uniform cold air in the ice making chamber 130, and at the same time, it is beneficial to provide coldness to the ice storage box 350 at the lower part of the ice maker 300, and prevent the ice cubes in the ice storage box 350 from melting.

[0115] Further, in the present embodiment, the ice maker 300 includes an ice making support 310 and an ice making tray 320 installed in the ice making support 310. The ice making support 310 may include a first side 311 and a second side 312, the first side 311 and the second side 312 may be arranged opposite to each other, and the first side 311 and the second side 312 may extend along the second direction Y. The air outlet 217 may be arranged beside the ice making support 310. Specifically, the ice making support 310 may be arranged beside the ice making refrigeration system 200, the first side 311 of the ice making support 310 is arranged adjacent to the first housing wall 213 of the refrigeration housing 210, the first side 311 of the ice making support 310 may be arranged beside the first housing wall 213, and the air outlet 217 is arranged beside the first side 311.

[0116] In this embodiment, see Fig.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 .

[0117] The support air inlet 330 may include a horizontal air inlet 331. The area of ​​the horizontal air inlet 331 may be greater than the area of ​​the support air outlet 340. Specifically, the area ratio of the horizontal air inlet 331 to the support air outlet 340 may be 2:1-3:2. The horizontal air inlet 331 may be at the same height as the support air outlet 340. The cold air flowing out of the air outlet 217 of the refrigeration housing 210 may enter the interior of the ice-making support from the horizontal air inlet 331 and flow out from the support air outlet 340.

[0118] The cold air entering from the horizontal air inlet 331 basically flows above the ice tray 320. By setting the area of ​​the bracket air outlet 340 to be smaller than the area of ​​the horizontal air inlet 331, the cold air can be retained above the ice tray 320. At the same time, the second side 312 of the ice-making bracket 310 can form a back block for the cold air entering from the horizontal air inlet 331, thereby forming an internal circulation vortex in the ice tray and improving the ice making rate.

[0119] 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 inclined toward the ice tray 320, thereby guiding the cold air into the ice tray 320. During the ice making process, the ice making grid of the ice tray 320 is filled with water, and the cold air entering from the ice surface air inlet 332 may be guided to blow directly toward the water surface in the ice tray 320, thereby accelerating the cooling of the water surface and improving the ice making rate.

[0120] The area of ​​the ice surface air inlet 332 is smaller than the area of ​​the horizontal air inlet 331. The ice surface air inlet 332 and the horizontal air inlet 331 can be arranged up and down. The area ratio of the horizontal air inlet 331 to the ice surface air inlet 332 can be 1.5-2.5. Preferably, the area of ​​the ice surface air inlet 332 can be half of the area of ​​the horizontal air inlet 331. The inclination angle of the ice surface air inlet 332 relative to the first direction X can be 22°-30°, so as to ensure that the cold air is blown to the water surface or the ice surface, and the cold amount is not too large, so as to avoid ice surface wrinkles caused by excessive cold amount.

[0121] Furthermore, in the present 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 inclined 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.

[0122] In this embodiment, the ice-making bracket 310 may further include a third side 313 and a fourth side 314 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 the third side 313 and the fourth side 314 may extend along the first direction X. The third side 313 may be located on one side with the third housing wall 215 of the refrigeration housing 210, and the fourth side 314 may be located on one side with 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.

[0123] In this embodiment, the end air inlet 333 may be disposed at one end of the ice-making bracket 310 close to the fourth side 314 and / or one end of the ice-making bracket 310 close to the third side 313. The end air inlet 333 disposed at one end of the ice-making bracket 310 close to the fourth side 314 may be inclined toward the fourth side 314, and the end air inlet 333 disposed at one end of the ice-making bracket 310 close to the third side 313 may be inclined toward the third side 313. The angle between the end air inlet 333 and the first direction X may be greater than 45°.

[0124] After the cold air blown out from the return air port 218 enters the interior of the ice-making bracket 310, a dead zone of the wind path is easily formed at the end of the ice-making bracket 310. The ice-making grid near the end receives less cold air and is not easy to freeze. Therefore, the ice-making grid at the end is likely to be not completely frozen when ice making is finished. Therefore, the end air inlet 333 is tilted to guide more air to the end ice-making grid, thereby increasing the cold air supplied to the end ice-making grid.

[0125] In a specific embodiment, the return air port 218 of the refrigeration housing 210 may be relatively close to one 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 toward the third side 313 of the ice-making bracket 310 relative to the first direction X. In this way, during the cold air circulation process, the cold air blown out from the refrigeration housing 210 is guided to the third side 313 of the ice-making bracket 310, so that the fourth side 314 of the ice-making bracket 310 is prone to have a dead zone in the air path. An end air inlet 333 inclined toward the fourth side 314 may be provided at one end of the fourth side 314 of the ice-making bracket 310 to guide the cold air to one end of the fourth side 314, so that the cold amount received by the ice tray 320 is as uniform as possible.

[0126] 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.

[0127] The second embodiment of the present invention further provides a refrigeration appliance. The refrigeration appliance of this embodiment is different from the refrigeration appliance of the first embodiment mainly in the structure of the ice-making refrigeration system 200.

[0128] See also Figures 15 to 18 , which is an ice-making refrigeration system according to the second embodiment of the present invention.

[0129] In this embodiment, the ice-making refrigeration system 200 includes a refrigeration housing 210, which is installed in the ice-making chamber 130. The ice-making evaporator 230 can be directly installed in the ice-making chamber 130. The ice-making evaporator 230 and the refrigeration housing can be installed on a wall of the ice-making chamber. The refrigeration housing 210 and a side wall of the ice-making chamber 130 together enclose an ice-making evaporator chamber, and the ice-making evaporator 230 is located in the ice-making evaporator chamber.

[0130] That is, in this embodiment, one end of the refrigeration housing 210 is open, and there is no connection between the ice-making evaporator 230 and the refrigeration housing 210, and the two are respectively installed on a wall surface of the ice-making chamber.

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

[0132] In a specific embodiment, the ice-making refrigeration system 200 can be installed on the top wall of the ice-making chamber 130. A mounting bracket 260 can be provided on the top of the ice-making chamber, and the mounting bracket 260 can be partially embedded in the foaming layer of the box body 100, and the top wall of the ice-making chamber 130 can extend into the interior of the ice-making chamber. During the installation process, the ice-making evaporator 230 can be connected to the mounting bracket 260 first, and the ice-making evaporator 230 can have an evaporator fixing portion 232, and the evaporator fixing portion 232 can be connected to the mounting bracket 260, such as the two can be fixedly connected by screws. Then, the air inlet pipe and the air return pipe of the ice-making evaporator can be welded to other refrigerant pipes of the refrigeration system, and then, the pre-assembled refrigeration shell module is connected to the mounting bracket 260. At this time, the refrigeration shell 210 is sealed with the top wall of the ice-making chamber 130, and the two together enclose the ice-making evaporator chamber.

[0133] In this embodiment, an air distribution part (not shown in the figure) may be provided at the return air outlet 218, wherein the structure of the air distribution part may be substantially the same as the structure of the air distribution part in the ice-making refrigeration system 200 of the first embodiment, and will not be described in detail here.

[0134] Furthermore, in this embodiment, the refrigeration housing 210 may be provided with an air outlet 280. The air outlet 280 may have an air outlet 217, and the air outlet 217 may be located at one side of the ice maker 300. The air outlet 280 is integrally formed with the refrigeration housing 210. Of course, the air outlet 280 may also be manufactured separately from the refrigeration housing 210 and then installed in the refrigeration housing 210. In this way, the cold energy in the refrigeration housing 210 can be directly guided to the ice maker 300, with high cold energy utilization and fast ice making speed.

[0135] In this embodiment, the ice-making refrigeration system 200 and the ice-making machine 300 are both arranged at the top of the ice-making chamber 130, and the ice-making refrigeration system 200 and the ice-making machine 300 can be arranged side by side along the width direction of the ice-making chamber 130. The ice-making evaporator 230 can be located at the front side of the fan 240.
