[0030] The present invention will now be described in detail 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 modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0031] See Figures 1 to 4 One embodiment of this utility model provides a refrigeration appliance, which can be a refrigerator. Figure 1 This is a simplified schematic diagram of a refrigeration appliance according to one embodiment of the present invention. Figure 2 This is a schematic diagram of the freezer compartment. Figure 3 and Figure 4 for Figure 2 A schematic diagram showing the components with some parts hidden.

[0032] The refrigeration appliance may include a refrigeration compartment. The refrigeration appliance may include a housing 100, within which a storage compartment may be formed. The storage compartment may include a refrigerator compartment 110, a freezer compartment 120, and may also include a variable temperature compartment. The refrigeration appliance may also include an ice-making compartment 130, within which an ice maker 300 may be installed. An ice storage box 350 may also be installed within the ice-making compartment 130, and the ice storage box 350 may be placed below the ice maker 300, allowing the user to remove the ice storage box 350 from the ice-making compartment 130. The refrigeration compartment may include either a storage compartment or an ice-making compartment 130.

[0033] 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 appliances 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.

[0034] The storage evaporator may include a refrigeration evaporator 111 that supplies cold air to the refrigeration compartment 110 and a freezing evaporator 121 that supplies cold air to the freezer compartment 120. The storage evaporator and the ice-making evaporator 230 may share a single compressor 150. By using an independent ice-making evaporator 230 to supply cold air to the ice-making compartment 130, the cold air in the ice-making compartment 130 can be kept clean and unaffected by the odors of food stored in the storage compartment, thus producing clean ice.

[0035] In one embodiment of this utility model, the ice-making chamber 130 is disposed within the freezer chamber 120, and the ice-making chamber 130 and the freezer chamber 120 are isolated from each other, meaning that there is no exchange of cold air between the ice-making chamber 130 and the freezer chamber 120. The refrigeration appliance includes a freezer door 122 for opening and closing the freezer chamber 120; when the freezer door 122 is closed, the ice-making chamber 130 is sealed. When the user needs to remove components such as the ice storage box 350 from the ice-making chamber 130, the freezer door 122 must be opened first.

[0036] In this embodiment, the refrigeration appliance may further include 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 box 350, such as the ice storage box 350 being pull-out and installed inside the ice-making chamber 130. The front panel of the ice storage box 350 can form the ice-making door 131. When the freezer door 122 is closed, the ice-making door 131 can be in a closed state, with the freezer door 122 covering the ice-making door 131. When the user needs to open the ice-making door 131, the freezer door 122 must be opened first.

[0037] The housing 100 may include an outer shell and an inner liner, with insulation material filling the space between them. In a specific embodiment, the insulation material may be foam. The housing 100 can be obtained by first foaming and molding the outer shell and the inner liner. The space inside the inner liner forms a storage compartment. After the housing 100 is manufactured, a partition 140 can be installed inside the freezer compartment 120 to directly separate the ice-making compartment 130. The partition 140 may be an insulated partition. In this embodiment, the ice-making compartment may be the space enclosed by the inner liner and the partition 140. A partition may be provided inside the ice-making compartment to separate an area for air ducts or for installing an evaporator, etc. The partition 140 is sealed to the side wall of the freezer compartment 120, such as through a sealing strip or other structure, to prevent cold air exchange between the ice-making compartment 130 and the freezer compartment 120. The partition 140 can be installed in the upper part of the freezer compartment 120, and the partition 140 together with the top wall and side wall of the freezer compartment 120 can form an ice-making compartment 130.

[0038] Of course, the storage room may also include a variable temperature compartment, and the ice maker 130 may also be located in the variable temperature compartment. The refrigeration appliances may include a variable temperature door for opening and closing the variable temperature compartment. When the variable temperature door is closed, the ice maker 130 can be sealed, and the user needs to open the variable temperature door to enter the ice maker 130. The method of setting the ice maker 130 in the variable temperature compartment is basically the same as the method of setting the ice maker 130 in the freezer compartment 120.

[0039] In one embodiment of this utility model, the refrigeration system of at least one refrigeration room can be installed inside the refrigeration room. The refrigeration system may include a refrigeration shell, an evaporator installed inside the refrigeration shell, and a fan. The refrigeration system may also include a water receiving tray, defrosting heating wire, and other components installed inside the refrigeration shell. The refrigeration system may include an air outlet and an air return outlet, which can be directly placed inside the refrigeration room.

[0040] In one specific embodiment of this utility model, the at least one refrigeration room is an ice-making room 130, and an ice-making refrigeration system 200 is installed in the ice-making room 130. The ice-making refrigeration system includes an ice-making evaporator 230.

[0041] For details, see Figures 5 to 13 This is a refrigeration appliance according to the first embodiment of the present invention. 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, which may include a refrigeration housing 210 and an ice-making evaporator 230, with the ice-making evaporator 230 located inside the refrigeration housing 210.

[0042] The ice-making and refrigeration system 200 may also include a fan 240, and further may include a drip tray 250 and a defrosting heating wire, all of which can be placed inside the refrigeration housing 210. The drip tray 250 can be placed at the bottom of the ice-making evaporator 230. When the ice-making evaporator 230 needs to defrost, the defrosting heating wire can be activated to heat it, and the water formed by the melting of frost on the surface of the ice-making evaporator 230 can flow into the drip tray 250.

[0043] The water tray 250 may have a drain nozzle 253, the side wall of the ice chamber 130 may be provided with a drain outlet, and a drain pipe 255 connected to the drain outlet may be installed in the insulation layer of the cabinet 100. The drain nozzle 253 of the water tray 250 may be inserted into the drain outlet, and the water in the water tray 250 may be discharged to the evaporating dish in the compressor chamber or directly to the outside of the refrigeration appliance through the drain pipe 255.

[0044] The ice-making and refrigeration system 200 may have an air outlet 217 and an air return outlet 218. The cooling capacity of the ice-making and refrigeration system 200 is directly transferred to the ice-making chamber 130 through the air outlet 217, resulting in minimal cooling capacity loss and significantly improving ice-making efficiency.

[0045] Both the air outlet 217 and the air return vent 218 can be located above the ice storage box 350. This reduces the impact of hot air on the ice storage box 350 during the defrosting process of the ice evaporator 230, as hot air does not easily sink. This also reduces the possibility of ice melting in the ice storage box 350 during the defrosting process. The air outlet 217 can be located on the wall opposite the refrigeration housing 210 and the ice maker, allowing the air blown from the outlet 217 to directly reach the ice maker. In one embodiment of this invention, the ice evaporator 230 can be located beside the ice maker 300, meaning the ice-making refrigeration system 200 can be located beside the ice maker 300. In this embodiment, with the user facing the ice maker 300 as a reference, the "side" can include the left, right, front, and rear sides of the ice maker 300.

[0046] In one embodiment of this utility model, 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 maker 300 can also be installed on the top of the ice-making chamber 130. The ice-making refrigeration system 200 and the ice maker 300 can be arranged side by side.

[0047] Specifically, the ice-making and refrigeration system 200 and the ice maker 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 its internal volume, 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, it prevents odors from the freezer chamber 120 from entering the ice-making chamber 130 through the gap between the partition 140 and the inner liner of the cabinet 100, thus preventing contamination of the ice in the ice-making chamber 130.

[0048] Of course, the ice-making and refrigeration system 200 and the ice maker 300 can also be arranged side by side along the depth direction of the ice-making chamber 130, such as the ice maker 300 being located on the front side and the ice-making and refrigeration system 200 being located on the rear side.

[0049] In this embodiment, see Figures 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 inside 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 installed on the mounting bracket 260. The lower refrigeration housing 212 is detachably installed on the upper refrigeration housing 211. The lower refrigeration housing 212 and the upper refrigeration housing 211 can be fastened together to form an ice-making evaporator chamber. The fan 240, the water tray 250, and the defrosting heating wire can all be placed in the ice-making evaporator chamber.

[0050] The ice-making evaporator 230 and the fan 240 can be installed on the upper housing 211 of the refrigeration unit, while the water tray 250 can be installed on the lower housing 212. The fan 240 can be detachably installed on the upper housing 211. During installation, pre-installed modules can be directly installed, making the installation process convenient. Furthermore, if a malfunction occurs during use, the lower housing 212 can be directly removed for repair.

[0051] See Figure 10 and Figure 12 The upper housing 211 of the refrigeration unit may be provided with a fan mounting slot 241, and the fan 240 may be installed in the fan mounting slot 241 by means of a snap fastener. The fan mounting slot 241 may include a side wall and a top wall, and both the side wall and the top wall of the fan mounting slot 241 may be provided with shock-absorbing springs. When the fan 240 is fixed to the upper housing 211 of the refrigeration unit by means of a snap fastener, the shock-absorbing springs can increase elasticity and reduce the rigid connection between the fan 240 and the upper housing 211 of the refrigeration unit, thereby reducing the vibration and noise during the operation of the fan 240.

[0052] The fan 240 may have a fan housing, which can form the air outlet duct of the fan 240. The cooling upper housing 211 may also be provided with a mounting groove that matches 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 cooling upper housing 211 to reduce vibration and noise during the operation of the fan 240.

[0053] The fan 240 can be installed at an angle relative to the horizontal plane on the upper housing 211 of the refrigeration unit. That is, the air outlet duct of the fan 240 can be tilted downwards, and the air outlet 217 of the fan 240 can form an angle of 5°-9° with the horizontal plane. The water collection tray 250 can be set below the fan 240. In this way, the water inside the fan housing can flow out from the air outlet of the fan 240 into the water collection tray 250 for discharge, preventing it from freezing inside the fan 240 and affecting the refrigeration.

[0054] The defrosting heating wire inside the ice-making refrigeration system 200 can be integrated into the ice-making evaporator 230. The ice-making evaporator 230 may include fins and refrigerant pipes, with the refrigerant pipes passing through and being fixed by the fins. The fins may also have holes for installing the defrosting heating wire, which can also pass through and be fixed by the fins. Aluminum plates 231 may also be provided at both ends of the ice-making evaporator 230, which can protect the defrosting heating wire and prevent it from being scratched. The ice-making evaporator 230 can be installed at an angle to facilitate the drainage of defrost water within it.

[0055] See Figure 9 and Figure 13The drip tray 250 may include a first drip section 251 located below the ice evaporator 230 and a second drip section 252 located below the fan 240. The first drip section 251 may be wavy, and both its upper and lower surfaces may be wavy.

[0056] A baffle 254 can be installed between the ice evaporator 230 and the drip tray 250. The baffle 254 can be fixed to the ice evaporator 230 and abut against the drip tray 250, or it can be fixed to the drip tray 250 and abut against the ice evaporator 230. The baffle 254 can reduce the amount of cold air flowing through the bottom of the ice evaporator 230 during the return air process, improving cooling efficiency. Furthermore, the baffle 254 can be a heat-conducting structure, thus transferring heat from the defrosting heating wire to the drip tray 250, preventing the water in the drip tray 250 from freezing. Also, during the return air process, some of the cold air returning to the refrigeration housing 210 flows through the drip tray 250. Since the temperature of the cold air returning to the refrigeration housing 210 is higher than the temperature of the cold air in the ice chamber 130, the temperature of the bottom surface of the refrigeration housing 210 can be increased, making the temperature inside the refrigeration housing 210 higher than that inside the ice chamber 130.

[0057] Meanwhile, the corrugated water tray 250 also reduces heat transfer to the outside, thus the temperature difference between the inside of the refrigeration housing 210 and the ice-making chamber 130 will not be too large. This allows for the use of a thinner insulation structure, ensuring that the inside of the refrigeration housing 210 does not frost up. Specifically, the refrigeration housing 210 may also be equipped with insulating foam 270, which can be 5mm EPS foam with a density of 30-40kg / m³.

[0058] The second water receiving portion 252 of the water receiving tray 250 can be a planar structure, thereby increasing the distance between it and the fan 240 and providing suction space for the fan 240. The second water receiving portion 252 of the water receiving tray 250 can be equipped with a drain nozzle, and an aluminum foil heating element can be laid on the second water receiving portion 252, which can extend into the drain nozzle 253 to prevent the drain nozzle 253 and the corresponding drain outlet of the housing 100 from freezing during the drainage process, ensuring smooth discharge of defrost water. The planar structure of the second water receiving portion 252 also facilitates the laying of the aluminum foil heating element.

[0059] The upper refrigeration housing 211 and the lower refrigeration housing 212 may be provided with mutually cooperating outlet holes 219, through which the inlet pipe and return pipe of the ice evaporator 230 can pass. A sealing flexible element, which can be foam, may be fitted over the inlet pipe and return pipe of the ice evaporator 230. When the upper refrigeration housing 211 and the lower refrigeration housing 212 are fastened together, the sealing flexible element can seal the gap between the inlet pipe and return pipe of the evaporator and the outlet hole 219.

[0060] In this embodiment, during the installation and manufacturing process, the insulation foam 270 can be installed into the lower refrigeration housing 212 first, the ice-making evaporator 230 and the fan 240 can be installed into the upper refrigeration housing 211, and components such as the water tray 250 can be installed into the lower refrigeration housing 212. Then, the upper refrigeration housing 211 and the lower refrigeration housing 212 are fastened together to form a pre-assembled module. Finally, the refrigeration housing 210 can be installed into the ice-making chamber 130. A sealing structure can be provided between the upper refrigeration housing 211 and the lower refrigeration housing 212 for sealing.

[0061] When the ice-making chamber 130 is located inside the freezer 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 can be installed into the ice-making chamber 130.

[0062] Specifically, the refrigeration housing 211 can be mounted on 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 drip tray 250. A drain outlet can be provided on the side wall of the freezer chamber 120 near the rear wall. 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, resulting in better insulation. Furthermore, 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.

[0063] Then, the inlet pipe of the ice-making evaporator 230 is directly pulled along the rear wall of the freezer compartment 120 to the compressor compartment for welding. The return pipe of the ice-making evaporator 230 can be pulled along the rear wall of the freezer compartment 120 to the compressor compartment for welding, or it can be directly pulled to the freezer evaporator 121 and welded to the inlet pipe of the freezer evaporator 121. When the return pipe of the ice-making evaporator 230 is welded to the inlet pipe of the freezer evaporator 121, part of the refrigerant from the compressor 150 can flow directly to the freezer evaporator 121 and then back to the compressor 150, while the other part flows through the ice-making evaporator 230 to the freezer evaporator 121 and then back to the compressor 150, thereby improving the cooling capacity utilization rate.

[0064] After the inlet and outlet pipes of the ice evaporator 230 are welded, the duct cover 160 and partition plate 140 of the freezer compartment 120 can be installed. The inlet and outlet pipes of the ice evaporator 230 can be placed between the duct cover 160 and the wall of the freezer compartment 120. The distance between the duct cover 160 and the refrigeration housing 210 can be greater than 18mm to facilitate installation by workers. The partition plate 140 directly divides the freezer compartment 120 into the ice-making compartment 130. In this way, the overall installation process is simple and quick. The multiple components will not interfere with each other.

[0065] In this embodiment, the air outlet 217 and the air return vent 218 of the ice-making and refrigeration system 200 can have different orientations. The opening directions of the air outlet 217 and the air return vent 218 are at an angle, specifically 90°. A gap can be left between one side wall of the ice-making and refrigeration system 200 and one side wall of the ice-making chamber 130 to form an airflow passage.

[0066] See Figure 5 The refrigeration appliance also includes an air distribution section 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 may be arranged side by side, and the first return air inlet 2181 may be located away from one side wall of the ice-making chamber 130 relative to the second return air inlet 2182. The second return air flow path includes an air intake that is at least partially oriented toward the airflow passage.

[0067] In this embodiment, the cold air in the ice-making chamber enters the second return air path from the air intake and then returns to the interior of the refrigeration housing from the second return air intake. This forces the airflow to pass through the airflow passage between one side wall of the ice-making chamber 130 and the refrigeration housing, thus avoiding dead zones in the airflow path between the side wall of the ice-making chamber 130 and the refrigeration housing.

[0068] In this embodiment, the area of ​​the first return air vent is less than or equal to 80% of the total return air vent area.

[0069] When the gap between one wall of the refrigeration housing and one side wall of the refrigeration chamber is small, the area of ​​the second return air inlet can be smaller than that of the first return air inlet, allowing more cold air to flow through the airflow path between them. Conversely, when the gap between one wall of the refrigeration housing and one side wall of the refrigeration chamber is large, the area of ​​the second return air inlet can be larger than that of the first return air inlet. This results in better airflow circulation and reduces dead zones in the airflow path.

[0070] In this embodiment, the air outlet 217 of the ice-making and refrigeration system 200 can be located on the side of the ice maker 300. Specifically, the refrigeration housing 210 may include a first housing wall 213 and a second housing wall 214 disposed opposite to each other. The air outlet 217 may be provided on the side of the first housing wall 213, and a gap may be left between the second housing wall 214 and one side wall of the ice-making chamber 130 to form an airflow passage. Specifically, a gap is left between the second housing wall 214 and the left side wall of the ice-making chamber 130 to form an airflow passage.

[0071] Specifically, in this embodiment, the cooling housing 210 may include a first housing wall 213 and a second housing wall 214 disposed opposite to each other in the first direction X, and a third housing wall 215 and a fourth housing wall 216 disposed opposite to each other in the second direction Y. The first direction X may be perpendicular to the second direction Y.

[0072] An air outlet 217 may be provided on one side of the first housing wall 213, that is, the air outlet 217 may be located on 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, located beside the ice maker 300. Of course, an opening may also be made in the first housing wall 213 to connect to an air duct, and the air duct may have an air outlet 217.

[0073] A return air inlet 218 may be provided on the side of the third housing wall 215. The opening direction of the return air inlet 218 may be perpendicular to the opening direction of the air outlet 217. The return air inlet 218 may be directly opened in the third housing wall 215, or an opening may be opened in the third housing wall 215 to connect to the air duct, and the air duct may have a return air inlet 218.

[0074] The first return air inlet 2181 and the second return air inlet 2182 are arranged side by side along a first direction X. The first return air inlet 2181 is located near the first housing wall 213, and the second return air inlet 2182 is located near the second housing wall 214. The second return air flow path includes an air intake at least partially facing the second housing wall 214. See also Figure 5 The airflow diagram shown by the arrows indicates that the air in the second return airflow path flows in at least partly from one side of the second housing 214.

[0075] In this embodiment, the ice-making and refrigeration system 200 and the ice maker 300 are arranged side by side, with the air outlet 217 located on one side of the first housing wall 213, making it difficult for airflow to flow towards the second housing wall 214. Specifically, when the ice-making and refrigeration system 200 is installed on 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 for airflow can easily form between the second housing wall 214 and the side wall of the ice-making chamber 130. This results in uneven temperature within the ice-making chamber 130.

[0076] By setting up the air distribution section 220, the return air inlet 218 is divided into a first return air inlet 2181 near the first housing wall 213 and a second return air inlet 2182 near the second housing wall 214, forming two return air flow paths. When the fan 240 is running, the fan 240 can force air to be drawn from both the first and second return air flow paths, so that part of the cold air in the ice-making chamber 130 flows from the first housing wall 213 side to the return air inlet 218, and the other part flows from the second housing wall 214 side to the return air inlet 218.

[0077] In this way, the cold air in the ice-making chamber 130 circulates from both sides of the ice-making and refrigeration system 200, avoiding dead zones in the airflow within the ice-making chamber 130. This results in a uniform temperature within the ice-making chamber 130, high utilization of cold air, good cooling effect, and improved ice-making efficiency of the ice maker 300.

[0078] Furthermore, in this embodiment, a return air panel 223 is also provided in the ice-making chamber 130. A gap is left between the return air panel 223 and the third housing wall 215 to form a return air flow path. The air distribution section 220 can be provided between the return air panel 223 and the third housing wall 215. The air distribution section 220 divides the return air flow path into a first return air flow path and a second return air flow path.

[0079] See Figure 4 In a specific embodiment, a sealing panel 223 is provided at the opening of the ice-making chamber 130, and the partial opening of the sealing panel 223 forms a channel for entering the ice-making chamber 130. An ice storage box 350 is removably installed in the ice-making chamber 130, 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 may be provided with a sealing strip; when the ice storage box 350 is closed, the sealing strip of the front panel of the ice storage box 350 can press 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 housing wall 215 of the refrigeration housing 210 to form a return air flow path.

[0080] Of course, an additional independent return air panel can be installed inside the ice-making chamber 130 to form a return air flow path between it and the third housing wall 215.

[0081] During the cold air circulation process, the cold air in the ice-making and refrigeration system 200 flows out from the air outlet 217, and then returns to the interior of the refrigeration housing 210 through the return air path and the return air outlet 218.

[0082] Furthermore, in this embodiment, see Figure 8 The air distribution section 220 includes a first air distribution rib 221 extending along a third direction and a second air distribution rib 222 extending from the end of the first air distribution rib 221 toward the second housing wall 214. The first air distribution rib 221 divides the return air inlet 218 into a first return air inlet 2181 and a second return air inlet 2182. The second air distribution rib 222 is located outside the return air inlet 218, that is, completely outside the return air inlet 218. The third direction is perpendicular to the first direction X and the second direction Y.

[0083] In this embodiment, the extension of the first wind rib 221 along the third direction can be such that the extension direction of the first wind rib 221 is completely coincident with the third direction, or the extension direction of the first wind rib 221 is slightly offset from the third direction, such as about 10°, that is, the first wind rib 221 extends approximately along the third direction.

[0084] When the ice-making and 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, there is basically no 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 flows between them. Therefore, at this time, the second air distribution rib 222 can be set at the lower part of the return air inlet 218, that is, the second air distribution rib 222 extends from the lower end of the first air distribution rib 221 towards the second housing wall 214.

[0085] In this way, the second air distribution rib 222 can prevent cold air from entering the second return air inlet 2182 from the lower end. The formation of the second return air flow path is basically oriented towards the air intake on the side of the second housing wall 214, which can promote more cold air to circulate back to the interior of the refrigeration housing 210 from the side of the second housing wall 214, reducing the dead zone of the air path in the ice-making chamber 130.

[0086] 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 housing wall 214. For example, when the lower part of the ice-making and refrigeration system 200 is provided with other wind-blocking structures, the cold air will basically not enter the second return air inlet 2182 from the lower part of the refrigeration housing 210. In this case, in order to encourage more cold air to circulate back into the refrigeration housing 210 from the side of the second housing wall 214, the second air distribution rib 222 can be set at the upper part of the second return air inlet 2182 to prevent cold air from entering the second return air inlet 2182 from the upper part of the second return air inlet 2182.

[0087] Of course, there can also be two second air distribution ribs 222, which extend from the upper end of the first air distribution rib 221 and the lower end of the second air distribution rib 222 toward the side of the second housing wall 214, respectively, to prevent cold air from returning to the interior of the refrigeration housing 210 from the upper and lower ends of the second return air inlet 2182.

[0088] Furthermore, in this embodiment, the second air distribution rib 222 includes a first air guide section 2221 connected to the first air distribution rib 221, and the first air guide section 2221 is inclined relative to the first direction X in the direction away from the return air inlet 218.

[0089] In this embodiment, when the second air distribution rib 222 extends from the lower end of the first air distribution rib 221 toward the second housing wall 214, the second air distribution rib 222 can tilt downwards; when the second air distribution rib 222 extends from the upper end of the first air distribution rib 221 toward the second housing wall 214, the second air distribution rib 222 can tilt upwards. The extension direction of the second air distribution rib 222 can form an angle of 3°-5° with the second direction Y, thereby increasing the suction area of ​​the second return airflow path.

[0090] Furthermore, in this embodiment, the second air distribution rib 222 also includes a second air guide section 2222, which 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 distribution rib 222, and the second air guide section 2222 can be inclined away from the return air outlet 218 in the first direction X relative to the first air guide section 2221.

[0091] 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 can be an arc segment. In this way, while preventing cold air from flowing in from the upper or lower side of the second return air inlet 2182, the air intake area of ​​the second return air flow path is increased, which is beneficial to the circulation of cold air.

[0092] Furthermore, in this embodiment, the return air vent 218 is directly formed on the third housing wall 215, and the air distribution section 220 is disposed on the third housing wall 215. The air distribution section 220 can be integrally formed with the third housing wall 215. The height of the air distribution section 220 along the second direction Y is greater than or equal to 10mm, 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 7mm to ensure the return air gap and avoid insufficient return air volume, which would cause frost to form on the surface of the return air vent 218 and affect the ice-making efficiency.

[0093] Furthermore, in this embodiment, a gap is left between the air distribution section 220 and the return air panel 223. Preferably, the distance between the air distribution section 220 and the return air panel 223 is less than 7mm.

[0094] It is understood that in the second direction Y, the distance between the first air distribution rib 221 and the second air distribution rib 222 and the return air panel 223 is less than 7mm. A micro-gap air duct is formed between the air distribution section 220 and the return air panel 223, which can improve the air circulation in the ice-making chamber 130, suppress frost formation, and form a frost-free space.

[0095] Furthermore, in this embodiment, the first direction X can be the width direction of the ice-making tray 320, and the second direction Y can be the length direction of the ice-making tray 320. The ice-making and refrigeration system 200 and the ice maker 300 are disposed on the top of the ice-making chamber 130 and can be arranged side by side along the first direction X. 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. 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 can be opposite to the rear wall of the ice-making chamber 130. The third housing wall 215 is located near the opening of the ice-making chamber 130, i.e., with the user facing the refrigerator as a reference, the third housing wall 215 is located in front of the fourth housing wall 216.

[0096] In this way, the space utilization rate of the ice-making chamber 130 can be improved, the internal volume of the ice-making chamber 130 can be reduced, and the cooling effect and ice-making efficiency of the ice maker 300 can be improved.

[0097] In this embodiment, the ice-making evaporator 230 and the fan 240 can be arranged along the second direction Y. The ice-making evaporator 230 can be arranged on the side close to the return air port 218. In this way, after the cold air enters the refrigeration housing 210 through the return air port 218, it 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, resulting in high cooling efficiency.

[0098] The ratio of the area of ​​the opposite side of the ice evaporator 230 and the return air vent 218 to the area of ​​the return air vent 218 can be 0.8-2.5.

[0099] 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 opposite to the return air vent 218 can be W*H. The area of ​​the return air vent 218 can be the sum of the areas of the first return air vent 2181 and the second return air vent 2182.

[0100] This configuration ensures that the air volume and velocity entering the refrigeration housing 210 from the return air vent 218 meet the needs of the ice evaporator 230, thereby improving the cooling capacity utilization of the ice evaporator 230, reducing frost formation on the surface of the ice evaporator 230, enhancing the cooling effect of the ice chamber 130, and accelerating the ice-making speed.

[0101] Furthermore, in this embodiment, in the second direction Y, the distance between the return air vent 218 and the ice evaporator 230 is greater than 5mm. This increases the frost-holding space, further reduces frost formation on the surface of the ice evaporator 230, improves the cooling effect of the ice chamber 130, and speeds up ice making.

[0102] In the third direction, the distance between the end of the return air vent 218 and the end of the evaporator is greater than 3mm. Specifically, the distance between the upper end of the return air vent 218 and the upper end of the ice-making evaporator 230 can be 6-10mm, or the distance between the lower end of the return air vent 218 and the lower end of the ice-making evaporator 230 can be 6-10mm. Alternatively, the upper and lower ends of the return air vent 218 can be 6-10mm from the upper and lower ends of the evaporator, respectively.

[0103] In this way, the return air vent 218 can be located as close as possible to the middle of the ice evaporator 230. The cold air entering the refrigeration housing 210 from the return air vent 218 can pass almost entirely through the middle of the ice evaporator 230. This allows frost to condense in the large space of the ice evaporator 230 as much as possible, avoiding frost overflow.

[0104] In the second direction Y, the distance between the evaporator and the air outlet 217 of the fan 240 is approximately 30-40mm, which can reduce the possibility of frost forming at the air outlet 217 of the fan 240.

[0105] The area ratio of the return air vent 218 to the air outlet vent 217 is 1.1-3, meaning the area of ​​the return air vent is larger than the area of ​​the air outlet vent, which can improve the utilization rate of the cooling air and reduce frost formation.

[0106] By setting it as described above, the ice-making and refrigeration system module 200 can be minimized, thereby minimizing the ice-making chamber 130, which can greatly improve the utilization rate of cooling capacity, reduce energy consumption, and increase the ice-making speed.

[0107] Furthermore, in this 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. In this way, an air guiding channel can be formed between the refrigeration housing 210 and the ice maker 300. Part of the air blown out from the air outlet 217 will flow directly down through the gap between the air outlet 217 and the ice maker 300, which is conducive to the uniform distribution of cold air in the ice chamber 130. At the same time, it is conducive to providing cooling to the ice storage box 350 at the bottom of the ice maker 300 and preventing the ice in the ice storage box 350 from melting.

[0108] Furthermore, in this embodiment, the ice maker 300 includes an ice-making support 310 and an ice-making tray 320 installed within the ice-making support 310. The ice-making support 310 may include a first side 311 and a second side 312, which may be arranged opposite to each other and may extend along a second direction Y. An air outlet 217 may be disposed beside the ice-making support 310. Specifically, the ice-making support 310 may be disposed beside the ice-making refrigeration system 200, with the first side 311 of the ice-making support 310 adjacent to the first housing wall 213 of the refrigeration housing 210, and the air outlet 217 disposed beside the first side 311.

[0109] In this embodiment, see Figure 14 The ice-making bracket 310 may be provided with an air inlet 330 on the first side 311 and an air outlet 340 on the second side 312.

[0110] 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 50mm. Cold air flowing from the air outlet 217 of the refrigeration housing 210 can enter the ice-making bracket through the horizontal air inlet 331 and flow out through the bracket air outlet 340.

[0111] The cold air entering through the horizontal air inlet 331 flows primarily above the ice-making tray 320. By making the area of ​​the support outlet 340 smaller than that of the horizontal air inlet 331, the cold air can be retained above the ice-making tray 320. Simultaneously, the second side 312 of the ice-making support 310 can deflect the cold air entering through the horizontal air inlet 331, thereby creating an internal circulation vortex within the ice-making grid and increasing the ice-making rate.

[0112] Furthermore, in this embodiment, the support air inlet 330 may also include an ice surface air inlet 332. The ice surface air inlet 332 can be tilted toward the ice-making tray 320, thereby guiding cold air into the ice-making tray 320. During the ice-making process, the ice grid of the ice-making tray 320 is filled with water, and the cold air entering from the ice surface air inlet 332 can be guided directly to the water surface in the ice-making tray 320, accelerating the cooling of the water surface and increasing the ice-making rate.

[0113] 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 vertically. 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 tilt angle of the ice surface air inlet 332 relative to the first direction X can be 22°-30° to ensure that the cold air is blown onto the water or ice surface without excessive cooling, thus preventing excessive cooling from causing wrinkles on the ice surface.

[0114] Furthermore, in this embodiment, the support air inlet of the ice maker 300 also includes an end air inlet 333 disposed at the end of the ice maker support 310 along the second direction Y. The end air inlet 333 can be tilted toward both ends of the ice maker 300 support, so that the cold air entering from the end air inlet 333 is guided to the end of the ice maker support 310.

[0115] In this embodiment, the ice-making bracket 310 may further include a third side 313 and a fourth side 314, which are connected to the first side 311 and the second side 312. The third side 313 and the fourth side 314 may extend along a first direction X. The third side 313 may be located on one side with the third housing wall 215 of the cooling housing 210, and the fourth side 314 may be located on one side with the fourth housing wall 216 of the cooling housing 210. A drive assembly may be mounted on the fourth side 314 of the ice-making bracket 310.

[0116] In this embodiment, the end air inlet 333 can be disposed at the end of the ice-making bracket 310 near the fourth side 314 and / or the end of the ice-making bracket 310 near the third side 313. The end air inlet 333 disposed at the end of the ice-making bracket 310 near the fourth side 314 can be inclined toward the fourth side 314, and the end air inlet 333 disposed at the end of the ice-making bracket 310 near the third side 313 can be inclined toward the third side 313. The angle between the end air inlet 333 and the first direction X can be greater than 45°.

[0117] After the cold air blown out of the return air vent 218 enters the ice-making bracket 310, a dead zone easily forms at the end of the ice-making bracket 310. The ice grid near the end receives less cold air and is not easy to freeze, often resulting in the end ice grid not being completely frozen when ice making ends. Therefore, tilting the end air inlet 333 can guide more airflow to the end ice grid, increasing the amount of cold air supplied to the end ice grid.

[0118] In a specific embodiment, the return air vent 218 of the refrigeration housing 210 can 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 can be tilted relative to the first direction X toward the third side 313 of the ice-making bracket 310. Thus, 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. Therefore, the fourth side 314 of the ice-making bracket 310 is prone to a dead zone in the airflow path. An end air inlet 333 tilted toward the fourth side 314 can be provided near the 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, so that the cold energy received by the ice-making tray 320 is as uniform as possible.

[0119] In summary, the ice-making chamber 130 can form a multi-dimensional, three-dimensional, enveloping airflow, resulting in uniform temperature, high cold air utilization, and fast ice-making speed.

[0120] See Figure 15 This is a refrigeration appliance provided as a second embodiment of the present invention.

[0121] The main difference between the refrigeration appliance of this embodiment and the refrigeration appliance of the first embodiment lies in the structure of the ice-making and refrigeration system 200.

[0122] In this embodiment, the ice-making and refrigeration system 200 includes a refrigeration housing 210, which is installed inside the ice-making chamber 130. The refrigeration housing 210 and one side wall of the ice-making chamber 130 together enclose an ice-making evaporator chamber.

[0123] The ice evaporator 230 can be directly installed inside the ice chamber 130. 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 evaporator 230 is installed, the pre-installed refrigeration housing module is connected to one wall of the ice chamber 130 to accommodate the ice evaporator 230 inside the ice evaporator housing 310.

[0124] 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 foam layer of the housing 100, with a portion of the top wall of the ice-making chamber 130 extending into the interior of the ice-making chamber. During installation, the ice-making evaporator 230 can be connected to the mounting bracket 260 first, and the inlet and outlet pipes of the ice-making evaporator can be welded to other parts of the refrigeration system. Then, the pre-installed refrigeration housing module can be connected to the mounting bracket 260. At this time, the refrigeration housing 210 is sealed to the top wall of the ice-making chamber 130, and the two together enclose the ice-making evaporator chamber.

[0125] In this embodiment, a wind distribution section 220 is provided at the return air vent 218, and the structure of the wind distribution section 220 is basically the same as that in the first embodiment.
