[0036] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] It should be understood that the terms used herein, such as "upper," "lower," "inner," and "front," etc., indicating spatial relative positions, are used for ease of explanation to describe the relationship of one component or feature relative to another component or feature as shown in the accompanying drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation other than the orientation shown in the drawings.

[0038] The present invention provides a refrigeration device. It is understood that the refrigeration device can be a refrigerator, a freezer, etc. Figure 1 As shown, the refrigeration device includes a housing 100 and a door for opening and closing the housing 100. A refrigeration compartment is formed within the housing 100, and the housing 100 includes an inner liner and an outer shell. The refrigeration compartment may include a storage compartment, an ice-making compartment 130, etc. The storage compartment may include a refrigerator compartment 110, a freezer compartment 120, and a variable temperature chamber. An ice-making machine may be placed in the ice-making compartment 130. The refrigeration device also includes an air duct cover installed within the storage compartment, forming an air duct between the air duct cover and the housing 100. The air duct cover may include a refrigerator air duct cover, a freezer air duct cover, etc.

[0039] In one embodiment of the present invention, the ice-making chamber 130 can be disposed within the storage compartment. Specifically, the ice-making chamber 130 can be disposed within the freezer compartment 120. For example, a heat-insulating partition 140 can be disposed within the freezer compartment 120 to separate the ice-making chamber 130. The ice-making chamber 130 can be the space enclosed by the inner liner of the freezer compartment 120 and the heat-insulating partition 140. As needed, partitions can be installed within the ice-making chamber 130 to separate the ice-making chamber 130. For example, partitions can be installed within the ice-making chamber 130 to form an air path for cold air flow, or partitions can be installed to define a space for installing components such as an evaporator. The door body can include a freezer door 122 that seals the freezer compartment 120, and an ice-making door 131 that seals the ice-making chamber 130.

[0040] The refrigeration equipment also includes a refrigeration system for providing cold air to the refrigerated compartment. The refrigeration system includes at least a compressor 150, a condenser, capillary tubes, and an evaporator. A compressor compartment 151 housing the compressor 150 is provided within the refrigeration equipment. The evaporator 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. The storage evaporator and the ice-making evaporator 230 may share the compressor 150, meaning that the refrigerant flowing out of the compressor 150 can selectively flow to either the storage evaporator or the ice-making evaporator 230. The storage evaporator may also include a refrigeration evaporator 111 for supplying cold air to the refrigerator compartment and a freezing evaporator 121 for supplying cold air to the freezer compartment. The capillary tubes may include an ice-making capillary tube connected to the ice-making evaporator 230, a refrigeration capillary tube connected to the refrigeration evaporator, and a freezing capillary tube connected to the freezing evaporator. Specifically, refrigerant from the compressor first flows through the corresponding capillary tube of the evaporator before being delivered to the corresponding evaporator. The various components of the refrigeration system can be connected by refrigerant pipes to form a circuit for the circulation of refrigerant.

[0041] In one embodiment of the present invention, the refrigerant flowing out of the compressor 150 can flow directly to the freezing evaporator 121 and then return to the compressor 150. Alternatively, the refrigerant can flow to the ice-making evaporator 230, enter the freezing evaporator 121 after passing through the ice-making evaporator 230, and then return to the compressor 150. This allows full utilization of the refrigerant provided by the compressor 150.

[0042] The refrigeration system may include a refrigeration module installed in the refrigeration compartment, the refrigeration module being configured to supply cold air to the refrigeration compartment. The refrigeration module may include a refrigeration housing forming an evaporator compartment, and an evaporator disposed in the evaporator compartment.

[0043] The refrigeration module can be a storage refrigeration module installed in the storage room to supply cold air to the storage room, or it can be an ice-making refrigeration module installed in the ice-making room to supply cold air to the ice-making room. It can be understood that the storage refrigeration module includes a storage evaporator, and the ice-making refrigeration module includes an ice-making evaporator.

[0044] The refrigeration module may also include a defrost heater and a water collection tray. The defrost heater is used to provide the evaporator with the heat required for defrosting. The water collection tray may be located below the evaporator to collect and drain the defrosted water from the evaporator. The refrigeration module may also include a fan to direct the cold air from the evaporator to the refrigeration compartment.

[0045] The refrigeration module of the present invention can be installed as an independent module at the supplier's site, which not only ensures the accuracy of the refrigeration module installation, but also reduces the difficulty of on-site installation of the refrigeration equipment and reduces the time of on-site installation of the refrigeration equipment.

[0046] See also Figures 2 to 19 As shown, in the specific embodiment provided by the present invention, the refrigeration module is an ice-making refrigeration module 200, which is installed in the ice-making chamber 130, and an ice-making machine 300 is installed in the ice-making chamber 130. The ice-making refrigeration module 200 is used to supply cold air to the ice-making chamber 130. The specific structure of the refrigeration module is described below using the ice-making refrigeration module 200 as a specific example. It can be seen that the left-right direction of the refrigeration device is the width direction, the front-back direction of the refrigeration device is the depth direction, and the up-down direction of the refrigeration device is the height direction. For ease of description, the width direction of the refrigeration device is defined as the first direction, the depth direction of the refrigeration device is defined as the second direction, and the height direction of the refrigeration device is defined as the third direction.

[0047] The ice-making refrigeration module 200 includes a refrigeration housing 210 installed within the ice-making chamber 130. The refrigeration housing 210 encloses an evaporator chamber. The ice-making refrigeration module 200 also includes an ice-making evaporator 230 disposed within the evaporator chamber, which provides cold air to the ice-making chamber. In this embodiment, the ice-making chamber 130 can be independently located within the freezer compartment, and the ice-making machine 300 within the ice-making chamber 130 is supplied with cold air by the independent ice-making refrigeration module 200. This prevents the ice produced by the ice-making machine 300 from odor cross-contamination and prevents microorganisms from entering the ice-making chamber and causing bacterial growth. Therefore, the ice-making machine 300 produces clean ice, ensuring consumer safety.

[0048] The refrigeration housing 210 is provided with an air return port 218 and an air outlet 217. It will be appreciated that the air return port 218 and the air outlet 217 connect the evaporator chamber to the ice-making chamber 130. Hot air in the ice-making chamber 130 enters the evaporator chamber through the air return port 218, exchanges heat with the ice-making evaporator 230, and is converted into cold air before entering the ice-making chamber 130 through the air outlet 217, thereby continuously providing cold air to the ice-making chamber 130.

[0049] In one embodiment of the present invention, the refrigeration housing 210 includes a first housing 211 and a second housing 212 connected to the first housing 211. The first and second housings 211, 212 are connected to form an evaporator chamber. The split design of the refrigeration housing 210 facilitates both processing and installation of the ice-making evaporator 230. Furthermore, the evaporator chamber formed by the first and second housings 211, 212 can seal the ice-making evaporator installed therein. Therefore, when installing the ice-making refrigeration module 200, there is no need to seal the connection between the ice-making refrigeration module 200 and the ice-making chamber 130.

[0050] In one embodiment of the present invention, the first shell 211 is connected to the ice-making chamber 130, the second shell 212 is detachably connected to the first shell 211, and the ice-making evaporator 230 is installed on the refrigeration shell 210. Specifically, the first shell 211 and the second shell 212 can be arranged one above the other, with the first shell 211 being connected to the ice-making chamber 130 and the second shell 212 being detachably connected to the lower side of the first shell 211. The first shell 211 and the second shell 212 can be connected by snapping. For example, a snap can be provided on the first shell 211, and a bayonet that cooperates with the snap can be provided on the second shell 212. Of course, it is understood that the snap is not limited to one structure, and multiple snaps can also be provided on the first shell 211 to improve the stability of the connection between the first shell 211 and the second shell 212.

[0051] The second housing 212 can be configured as a box structure with a storage space, with an opening in communication with the storage space at its upper portion. The first housing 211 can be configured as a cover structure. After the first and second housings 211 and 212 are connected, the first housing 211 seals the opening of the second housing 212 to form a sealed evaporator chamber. It is understood that the specific structures of the first and second housings 211 and 212 are not limited thereto.

[0052] In other embodiments of the present invention, the first shell 211 and the second shell 212 can be arranged in any one of the first direction, the second direction, and the third direction. In addition, the specific structures of the first shell 211 and the second shell 212 can be adjusted according to actual needs.

[0053] The ice-making evaporator 230 includes a refrigerant pipe 260, and the refrigerant pipe 260 may include an ice-making air inlet pipe 263 and an ice-making air return pipe 262. The refrigeration shell 210 is provided with an outlet hole 219 for the refrigerant pipe 260 to pass through. Specifically, the first shell 211 and the second shell 212 are snapped together to form the outlet hole 219 for the refrigerant pipe 260 to enter and exit. The outside of the refrigerant pipe 260 is wrapped with a flexible member, such as a protective sleeve, and the inner wall of the outlet hole 219 presses the flexible member. In one embodiment of the present invention, the outlet hole 219 includes a first hole section 2191 located in the first shell 211 and a second hole section 2192 located in the second shell 212. After the first shell 211 and the second shell 212 are connected, the first hole section 2191 and the second hole section 2192 simultaneously press the protective sleeve, thereby sealing the outlet hole 219 and preventing frost from forming at the outlet hole 219.

[0054] The refrigeration housing 210 also includes a wire outlet 270, through which the wiring harness within the ice-making refrigeration module 200 passes and is powered by the refrigeration equipment. Specifically, the wire outlet 270 includes an upper wire outlet section located in the first housing 211 and a lower wire outlet section located in the second housing 212. Sealing ribs 271 are protruding from the inner walls of the upper wire outlet section and / or the lower wire outlet section. When the first housing 211 and the second housing 212 are connected, the sealing ribs 271 press against the wiring harness, thereby sealing the wire outlet 270.

[0055] In one embodiment of the present invention, the ice evaporator 230 includes a fin assembly 233 and a lower aluminum plate 232 connected to the underside of the fin assembly 233. The ice evaporator may also include an upper aluminum plate 231 connected to the upper side of the fin assembly 233. The upper aluminum plate 231 and the lower aluminum plate 232 may be riveted to the fin assembly 233. The ice evaporator 230 may be mounted on the first housing 211. If the ice evaporator 230 later malfunctions, the second housing 212 may be removed for convenient repair.

[0056] The ice-making refrigeration module 200 also includes a defrost heating wire installed in the evaporator chamber. Specifically, the defrost heating wire can be an aluminum tube heating wire. In one embodiment of the present invention, the defrost heating wire is integrated into the ice-making evaporator 230. For example, embedding the defrost heating wire in the fin assembly 233 not only saves space in the evaporator chamber for placing the defrost heating wire, but also increases the contact area between the defrost heating wire and the fin assembly 233, allowing the ice-making evaporator 230 to defrost quickly. In addition, the upper aluminum plate 231 and the lower aluminum plate 232 of the ice-making evaporator 230 limit and protect the defrost heating wire in the upper and lower positions to prevent the defrost heating wire from being scratched during use.

[0057] The ice-making refrigeration module 200 also includes a water receiving pan installed in the evaporator room. In one embodiment of the present invention, the water receiving pan 250 includes a bottom wall and a water retaining wall 256 extending upward from the periphery of the bottom wall. The upper edge of the water retaining wall 256 is not lower than the upper edge of the ice-making evaporator 230. It can be understood that the upper edge of the water retaining wall 256 can be flush with the upper edge of the ice-making evaporator 230, or the upper edge of the water retaining wall 256 is higher than the upper edge of the ice-making evaporator 230. Since the ice-making refrigeration module 200 is installed as an independent module as a whole before docking with the drain outlet 170 on the box body 100, the upper edge of the water retaining wall 256 can be set to be not lower than the upper edge of the ice-making evaporator 230, thereby effectively blocking the overflow of defrost water and avoiding the risk of defrost water overflow in the prior art.

[0058] The water retaining wall 256 of the water receiving tray 250 is arranged to avoid the positions of the return air port 218 and the air outlet 217. The other structures of the ice making and refrigeration module 200 are also arranged to avoid the positions of the air outlet 217 and the return air port 218, thereby ensuring smooth return and outlet of the evaporator chamber.

[0059] The ice-making refrigeration module 200 further includes a fan 240 disposed in the evaporator chamber. The fan 240 guides the cold air from the evaporator to flow quickly to the ice-making chamber, shortening the cold air transmission time of the evaporator, thereby improving the cold air utilization rate of the evaporator.

[0060] The fan 240 is detachably connected to the refrigeration housing 210 or the water tray 250. The refrigeration housing 210 is provided with a return air vent 218 communicating with the ice-making chamber 130. The ice-making evaporator 230 is located between the fan 240 and the return air vent 218. The fan 240 is located on the side of the ice-making evaporator 230 away from the return air vent 218. In one embodiment of the present invention, the fan 240 is mounted on the first housing 211, the air outlet 217 and the return air vent 218 are both provided on the second housing 212, and the ice-making evaporator 230 is located between the fan 240 and the return air vent 218. This ensures that most of the hot air entering the evaporator chamber through the return air vent 218 flows through the ice-making evaporator 230 for heat exchange. Specifically, the fan 240 includes an air inlet side and an air outlet side. The air inlet side of the fan 240 is arranged close to the ice-making evaporator 230, and the air outlet side of the fan 240 is arranged close to the air outlet 217. The hot air in the ice-making chamber 130 enters the evaporator chamber through the return air port 218 and exchanges heat with the ice-making evaporator 230 to become cold air. Then the cold air flows through the air inlet side, the air outlet side, and the air outlet 217 of the fan 240 in sequence and finally enters the ice-making chamber 130, thereby quickly cooling the ice-making chamber 130.

[0061] In one embodiment of the present invention, the fan 240 is detachably connected to the first housing 211. The first housing 211 is provided with a fan mounting slot 241, and the fan 240 is detachably mounted in the fan mounting slot 241. Specifically, the fan 240 can be horizontally arranged in the fan mounting slot 241. The fan mounting slot 241 facilitates positioning of the fan 240 during installation. In addition, when the fan 240 fails, it can be easily replaced or repaired by removing the second housing 212. Furthermore, a plurality of clips for connecting the fan 240 are provided in the fan mounting slot 241, thereby ensuring the reliability of the fan 240 being installed in the fan mounting slot 241. In addition, a shock-absorbing member abutting against the fan 240 is also provided in the fan mounting slot 241 to reduce the noise generated by the vibration of the fan 240.

[0062] See Figure 17 As shown, in another embodiment of the present invention, the difference from the previous embodiment is that the fan 240 is fixed on the water receiving tray 250. In order to clearly show the positional relationship between the ice evaporator 230 and the fan 240, Figure 17 The refrigeration shell 210 is hidden, and the way in which the fan 240 is fixed to the water receiving tray 250 is not limited. For example, a fixing part for fixing the fan 240 is set on the water receiving tray 250, and the fan 240 can be placed vertically in the evaporator chamber, thereby further reducing the size of the module solution along the depth direction of the refrigerator, increasing the versatility of the ice-making refrigeration module, and making the ice-making refrigeration module more suitable for refrigeration equipment with smaller space.

[0063] The refrigerant pipe 260 of the ice-making evaporator 230 has a pipe joint near the fan 240. The pipe joint is arranged in the evaporator chamber to fully utilize the space of the evaporator chamber. The outer periphery of the pipe joint is wrapped with an insulation layer 261 to prevent frost on the fan 240.

[0064] In one embodiment of the present invention, the bottom wall of the water receiving tray 250 includes 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 has alternating raised portions 2511 and groove portions 2512. It can be understood that the first water receiving portion 251 and the second water receiving portion 252 are connected. The first water receiving portion 251 below the ice-making evaporator 230 is a wave-shaped structure in which the raised portion 2511 is a crest and the groove portion 2512 is a trough. The groove portion 2512 can collect the defrost water of the ice-making evaporator 230 and leave a channel for a part of the hot air entering the evaporator room to flow through the water receiving tray 250, so that the temperature at the bottom of the ice-making evaporator 230 is higher than the evaporator temperature. In addition, there is a gap between the lower side of the protrusion 2511 and the refrigeration shell, and the air can reduce heat transfer, thereby reducing the temperature difference between the bottom temperature of the evaporator chamber and the refrigeration chamber. Therefore, the first water receiving portion 251 structure in the present invention can achieve an ultra-thin insulation structure of the ice-making refrigeration module 200 while ensuring that the ice-making evaporator chamber 230 is not frosted, thereby reducing the overall size of the ice-making refrigeration module 200 and improving the space utilization rate of the ice-making chamber.

[0065] In one embodiment of the present invention, the ice-making refrigeration module 200 and the ice-making machine 300 are arranged in parallel in the ice-making chamber 130 along a first direction, and the ice-making evaporator 230 and the fan 240 are arranged in the evaporator chamber along a second direction. The raised portion 2511 and the groove portion 2512 both extend along the second direction and are alternately arranged along the first direction, so that the first water receiving portion 251 is a continuous wavy structure along the first direction, and the first water receiving portion 251 has sufficient length in both the first and second directions to cover the projected area of the ice-making evaporator 230, thereby increasing the area of the groove portion 2512 for collecting defrost water and the area of the raised portion 2511 in contact with hot air.

[0066] Furthermore, the second water receiving portion 252 is configured as a flat surface, thereby leaving sufficient air suction distance for the fan 240. In one embodiment of the present invention, the fan 240 is arranged at an angle along the second direction at the top of the evaporator chamber. The side of the fan 240 closer to the ice-making evaporator 230 is higher than the side farther away from the ice-making evaporator 230. The second water receiving portion 252 is a flat surface in the same direction of inclination as the fan 240, further increasing the air suction distance of the fan 240 and improving the air guiding effect of the fan 240.

[0067] In one embodiment of the present invention, the refrigeration device includes a drain pipe 255. The housing 100 is provided with a drain port 170 connected to the drain pipe 255. The water receiving tray 250 is provided with a drain nozzle 253, which can be connected to the drain port 170. The drain nozzle 253 can be provided on the second water receiving portion 252. The first water receiving portion 251 is tilted along the second direction, and the side of the first water receiving portion 251 closer to the second water receiving portion 252 is lower than the side of the first water receiving portion 251 farther from the second water receiving portion 252. This allows water collected in the groove portion 2512 on the first water receiving portion 251 to flow toward the second water receiving portion 252 and into the drain pipe 255 of the refrigeration device through the drain nozzle 253 on the second water receiving portion 252, thereby achieving rapid discharge of defrost water.

[0068] In one embodiment of the present invention, the drain nozzle 253 is disposed on the side of the second water receiving portion 252 away from the first water receiving portion 251. Since the side of the second water receiving portion 252 closer to the first water receiving portion 251 is higher than the side farther away from the first water receiving portion 251, the drain nozzle 253 is disposed at the lowest side of the second water receiving portion 252 to ensure that all defrost water flowing into the second water receiving portion 252 flows into the drain nozzle 253 and ultimately into the drain pipe 255.

[0069] Furthermore, an aluminum foil heating wire is installed near the drain nozzle 253 on the second water receiving portion 252 to prevent ice blockage at the drain nozzle 253 and ensure smooth discharge of defrost water. Since the second water receiving portion 252 is flat, it is very convenient to lay the aluminum foil heating wire. Of course, the choice of heating wire for the drain nozzle 253 is not limited to aluminum foil.

[0070] The ice-making refrigeration module 200 also includes a windshield 254 disposed between the ice-making evaporator 230 and the water receiving tray 250. The windshield 254 can be disposed on or connected to the ice-making evaporator 230 or the water receiving tray 254. The windshield 254 is used to partially shield the gap between the ice-making evaporator 230 and the water receiving tray 250. Without affecting the flow of defrost water in the water receiving tray 250, the windshield 254 can prevent most of the hot air entering the evaporator chamber from passing through the gap between the ice-making evaporator 230 and the water receiving tray 250. This allows most of the hot air entering the evaporator chamber to be cooled by the ice-making evaporator 230 before being guided by the fan 240 into the ice-making chamber 130, thereby ensuring a supply of cold air to the ice-making chamber 130.

[0071] In one embodiment of the present invention, see Figure 10 and Figure 14As shown, the wind shield component 254 is arranged at the lower end of the ice-making evaporator 230. Specifically, the wind shield component 253 is a convex rib protruding from the lower end surface of the lower aluminum plate 232 toward the water receiving pan 250, and the height of the convex rib is less than the height of the gap between the lower aluminum plate 232 and the water receiving pan 250. The convex rib shields part of the gap between the ice-making evaporator 230 and the water receiving pan 250, thereby preventing the hot air entering the evaporator room from directly flowing through the gap between the ice-making evaporator 230 and the water receiving pan 250. Most of the hot air entering the evaporator room through the return air inlet 218 undergoes heat exchange with the ice-making evaporator 230 and then is guided to the ice-making chamber 130 through the fan 240, thereby improving the cooling efficiency of the ice-making evaporator 230 while not affecting the flow of defrost water in the water receiving pan 250.

[0072] In another embodiment of the present invention, see Figure 18 and Figure 19 As shown, the windshield member 254 is provided on the water receiving tray 250. Specifically, the windshield member 254 is a rib protruding from the upper end surface of the water receiving tray 250. The rib can protrude from the upper end surface of the water receiving tray 250 toward the ice making evaporator 230. Of course, it is understood that the arrangement of the windshield member 254 is not limited to this.

[0073] See Figure 14 As shown, the windshield member 254 comprises a plurality of ribs spaced apart along the first direction, each rib being located within a recessed portion 2512. The ribs are positioned correspondingly to the recessed portions 2512, effectively shielding a portion of the gap between the lower aluminum plate 232 and the recessed portion 2512 of the water receiving tray 250. This prevents the majority of hot air entering the evaporator chamber from flowing directly through the gap between the ice-making evaporator 230 and the water receiving tray 250. Instead, the majority of hot air entering the evaporator chamber through the return air port 218 undergoes heat exchange with the ice-making evaporator 230 before flowing through the fan 240. Furthermore, the height of the ribs is less than the distance between the lower aluminum plate 232 and the bottom of the recessed portion 2512, ensuring that the ribs do not affect the flow of defrost water within the water receiving tray 250.

[0074] The wind shielding member 254 is a plurality of rows of ribs spaced apart along the second direction, further ensuring that most of the hot air entering the ice making chamber 130 through the return air port 218 undergoes heat exchange with the ice making evaporator 230 before entering the fan 240 .

[0075] Furthermore, the windshield component 254 is made of a heat-conducting material. In this embodiment, the defrost heating wire is integrated on the ice-making evaporator 230. When the ice-making evaporator 230 is defrosted, the heat of the defrost heating wire can be guided to the water receiving tray 250, so that the defrost water on the water receiving tray 250 will not freeze.

[0076] In one embodiment of the present invention, the ice-making evaporator 230 is tilted in the evaporator chamber. When the ice-making evaporator 230 defrosts, the tilted arrangement of the ice-making evaporator 230 makes it easier for the water receiving tray 250 to collect the defrosted water and discharge the defrosted water.

[0077] In this embodiment, the ice-making refrigeration module 200 also includes an insulation component 290 arranged between the refrigeration shell 210 and the water receiving tray 250 to reduce heat transfer between the evaporator chamber and the ice-making chamber 130, reduce heat transfer between the evaporator chamber and the ice-making chamber 130, and reduce frost in the evaporator chamber.

[0078] Specifically, a heat-insulating member 290 is provided between the water receiving tray 250 and the second shell 212. The heat-insulating member 290 is provided to fit the periphery of the water receiving tray 250. The second shell 212 is provided to fit the periphery of the heat-insulating member 290. The heat-insulating member 290 can be provided with the bottom wall of the water receiving tray 250 and the water retaining wall 256. The heat-insulating member 290 can be provided with a density of 30 kg / m 3 -40kg / m 3 EPS foam board. Due to the wavy bottom structure of the first water receiving portion 251 of the water receiving tray 250 in this embodiment, the thermal insulation member 290 can be set to an ultra-thin EPS foam board of 5 mm. The thickness of the foam board can be set to different positions.

[0079] The upper end of the first water receiving portion 251 can abut against the lower end of the ice-making evaporator 230, and the lower end of the first water receiving portion 251 abuts against the thermal insulation component 290, so that the ice-making evaporator 230, the water receiving tray 250 and the thermal insulation component 290 in the evaporator chamber are compactly arranged, further reducing the overall size of the ice-making refrigeration module 200.

[0080] In this embodiment, the refrigeration device includes an inner container and a hanger 180 connected to the inner container, and the ice-making refrigeration module 200 is connected to the hanger 180. The ice-making refrigeration module 200 and the hanger 180 can be directly or indirectly connected. Specifically, the ice-making refrigeration module 200 is installed on the top of the freezer compartment 120. The hanger 180 is provided on the top of the inner container of the freezer compartment. The ice-making refrigeration module 200 is slidably connected to the hanger 180. The ice-making refrigeration module 200 is installed on the top of the ice-making compartment 130 by sliding connection. The operation is simple and convenient, saving installation time. Figure 5As shown, the hanger 180 has a slide 181 extending axially along the drain outlet 170. The axial direction of the drain outlet 170 can be understood as a direction perpendicular to the imaginary plane in which the drain outlet 170 is located. The refrigeration housing 210 is provided with guide ribs 214 that cooperate with the slide 181. Specifically, the guide ribs 214 can be disposed on the first housing 211. The cooperation between the guide ribs 214 and the slide 181 reliably connects the ice-making refrigeration module 200 to the hanger 180. Of course, the method of installing the ice-making refrigeration module 200 on the top of the freezer compartment 120 is not limited to this. For example, the ice-making refrigeration module 200 can also be installed by sliding along the axial direction of the drain outlet 170 in the first half of the travel and rotating and fixing in the second half.

[0081] In one embodiment of the present invention, the drain port 170 is disposed on one side wall of the inner container that is opposite to the two side walls along the first direction. For example, the drain port 170 is disposed on the left side wall. The slide 181 is a pair of slides 181 extending along the first direction and arranged opposite to each other along the second direction, each of the slides 181 includes a first slide section 1811 and a second slide section 1812 spaced apart along the first direction; the guide ribs 214 include a pair of guide ribs 214 spaced apart along the second direction, the guide ribs 214 extend along the first direction, and each of the guide ribs 214 includes a first guide rib portion 2141 and a second guide rib portion 2142 spaced apart along the first direction. When the ice-making system module is installed along the first direction, the first guide rib portion 2141 is first inserted into the second slide section 1812, and then the first guide rib portion 2141 moves toward the first slide section 1811 until the first guide rib 214 cooperates with the first slide section 1811 and continues to slide the second guide rib portion 2142 to cooperate with the second slide section 1812. This avoids the need to align the first guide rib portion 2141 and the second guide rib portion 2142 at the same time during installation, thereby reducing the difficulty of installation.

[0082] In one embodiment of the present invention, an elastic stopper may be provided on the bracket 180. When installing the ice-making refrigeration module 200, the elastic stopper needs to be pressed in advance to shrink the elastic stopper. After the ice-making refrigeration module 200 is installed in place, the elastic stopper automatically rebounds, thereby limiting the ice-making refrigeration module 200 in the first direction, so that the ice-making refrigeration module 200 remains in a fixed position after installation.

[0083] The refrigeration shell 210 is also provided with a plurality of threaded holes. For example, a first threaded hole and a second threaded hole for screws to pass through are correspondingly provided on the first shell 211 and the second shell 212. Thus, after the ice-making refrigeration module 200 is slidably connected to the bracket 180, the ice-making refrigeration module 200 and the bracket 180 are reinforced and fixed by screws, thereby further improving the reliability of the ice-making refrigeration module 200 connected to the ice-making chamber 130.

[0084] In one embodiment of the present invention, the refrigerant pipe 260 of the ice-making evaporator 230 passes through the pipe outlet 219 and passes into the compartment air duct to be connected with other refrigerant pipes of the refrigeration system, or enters the compressor chamber 151 through the compartment air duct to be connected with other refrigerant pipes of the refrigeration system.

[0085] Specifically, when the ice-making chamber 130 is arranged in the freezing chamber 120, the air duct cover 160 is a freezing air duct cover, and the refrigerant pipe 260 of the ice-making evaporator 230 can be connected to other refrigerant pipes of the refrigeration system by welding.

[0086] During the installation process, the ice-making refrigeration module 200 can be installed on the top of the ice-making chamber 130 first, and then the refrigerant pipe 260 of the ice-making refrigeration module 200 can be welded to other refrigerant pipes in the compartment air duct. After welding is completed, the air duct cover 160 can be installed. Since there is ample space for welding, the installation difficulty for workers is reduced and the installation time is shortened.

[0087] In the present invention, the top of the ice-making chamber 130 does not need to be pre-installed with pipe joints, and the refrigerant pipe 260 and other refrigerant pipes of the refrigeration system do not need to be welded in the ice-making chamber 130. Instead, they are connected in the spacious compartment air duct or the compressor chamber 151, thereby avoiding the risk of damage to the pipe joints after being bent, which may lead to an increase in the scrap rate of the refrigeration equipment.

[0088] Specifically, a pipe outlet portion 213 is provided on a side of the refrigeration housing 210 near the air duct cover 160, and the pipe outlet hole 219 is provided in the pipe outlet portion 213. The air duct cover 160 is provided with a relief groove 161 for the pipe outlet portion 213 to pass through to the air duct in the compartment. A sealing member, such as foam, is provided between the pipe outlet portion 213 and the relief groove 161 to seal the relief groove 161 and prevent frost from forming thereon.

[0089] In one embodiment of the present invention, the avoidance groove 161 is formed by being recessed downward from the upper edge of the air duct cover 160, and the avoidance groove 161 includes a guide arc 162 located at the groove. Since in the present invention, the air duct cover 160 is installed after the refrigerant pipe 260 of the ice-making evaporator 230 and other refrigerant pipes of the refrigeration system are welded, when the air duct cover 160 is installed and the position is offset, the guide arc 162 of the avoidance groove 161 will first contact the bottom side surface of the outlet pipe 213 of the ice-making refrigeration module 200. When the freezing air duct cover 160 continues to be installed, the guide arc 162 guides the air duct cover 160 to move to the avoidance groove 161 and align with the outlet pipe 213 according to the shape of the bottom side surface of the outlet pipe 213. Therefore, the avoidance groove 161 of the air duct cover 160 of this embodiment has a self-guiding function. Furthermore, the width of the opening of the avoidance groove 161 may be set to be greater than or equal to the width of the bottom of the avoidance groove, which is more conducive to the installation of the air duct cover 160.

[0090] The ice-making refrigeration module 200 further includes an insulation tube disposed around the outer periphery of the refrigerant tube 260 in the compartment air duct to prevent frost on the refrigerant tube 260 in the compartment air duct. The insulation tube needs to be positioned at a safe distance from the welds between the refrigerant tube 260 and other refrigerant tubes.

[0091] In this embodiment, the refrigerant pipe 260 includes an ice-making return pipe 262 and an ice-making inlet pipe 263. The storage evaporator includes a refrigeration inlet pipe located within the compartment air duct. The following description of the connection of the refrigerant pipe 260 uses the specific embodiment of the ice-making chamber 130 being located within the freezer compartment 120. However, the ice-making chamber 130 is not limited to being located within the freezer compartment 120.

[0092] In this embodiment, the storage evaporator is specifically a freezer evaporator, and the refrigeration inlet pipe is specifically a freezer inlet pipe connected to the freezer evaporator. The ice-making inlet pipe 263 of the ice-making evaporator 230 is connected to the ice-making capillary tube, and the ice-making return pipe 262 is connected to the freezer inlet pipe of the freezer evaporator 121. Specifically, the refrigerant from the compressor 150 partially enters the ice-making capillary tube after passing through the condenser, then flows sequentially through the ice-making evaporator 230 and the freezer evaporator 121 before returning to the compressor 150. The connection in this embodiment can be direct or indirect.

[0093] Specifically, the refrigeration system includes a first air inlet pipe located within the compartment air duct. The first air inlet pipe can be an ice-making capillary tube or an air inlet pipe connected to the ice-making capillary tube. The refrigerant pipe of the ice-making evaporator also includes a second air inlet pipe. The second air inlet pipe can be an ice-making air inlet pipe 263 or an air inlet pipe connected to the ice-making air inlet pipe 263. The second air inlet pipe is connected to the first air inlet pipe within the compartment air duct, achieving an indirect connection between the ice-making capillary tube and the ice-making air inlet pipe 263. In an embodiment, the ice-making return air pipe and the refrigeration air inlet pipe are also connected within the compartment air duct. The compartment air duct is relatively spacious, making it easier for workers to weld and install, reducing the difficulty of refrigerant pipe installation and saving installation time.

[0094] Specifically, the specific direction of the refrigerant pipe 260 in the evaporator room after it is led out from the pipe outlet 219 is: the refrigerant pipe 260 goes downward into the freezer compartment air duct, the ice-making return air pipe 262 and the freezer evaporator's freezer air inlet pipe are welded inside the freezer compartment, the first air inlet pipe and the second air inlet pipe are welded inside the freezer compartment, and then the freezer air duct cover 160 is installed, so there is ample space for workers to weld, reducing the difficulty of installation.

[0095] In one embodiment of the present invention, a compression pipe clamp and a shock absorber connected to the compression pipe clamp are further provided in the compartment air duct. The compression pipe clamp is used to fix the refrigerant pipe 260 and other refrigerant pipes connected to the refrigerant pipe 260, so that the refrigerant pipe 260 and other refrigerant pipes are connected and fixed in the compartment air duct, and the shock absorber is used to reduce the noise generated by the vibration of the refrigerant pipe 260 and other refrigerant pipes of the ice-making evaporator 230 when the refrigeration system is running.

[0096] In another embodiment of the present invention, a pipe clamp, a pipe whole, and a shock absorber connected to the pipe clamp or / and the pipe whole are further provided in the compartment air duct. The refrigerated air inlet pipe is fixed to the back of the box 100 by the pipe clamp, and the refrigerant pipe 260 and the first air inlet pipe are connected to the refrigerated air inlet pipe by the pipe whole. It can be seen that the refrigerant pipe 260 includes an ice-making air inlet pipe 263 and an ice-making return air pipe 262. The refrigerated air inlet pipe, the first air inlet pipe, the ice-making return air pipe 262, and the second air inlet pipe in the compartment air duct are all fixed to the box 100 by the cooperation of the pipe clamp and the pipe whole, and the noise generated by the vibration of the refrigerant pipe 260 and other refrigerant pipes of the ice-making evaporator 230 when the refrigeration system is running is reduced by the shock absorber.

[0097] In one embodiment of the present invention, the refrigeration unit further includes a terminal block assembly 280 embedded in the ice-making chamber 130. This terminal block assembly 280 is used to connect to and power the wiring harness leading from the wire outlet 270, thereby resolving wiring issues within the ice-making chamber 130 and avoiding condensation-induced short circuits caused by placing the terminal block assembly 280 at the back of the refrigeration unit. It is understood that the wiring harness leading from the wire outlet 270 is the wiring harness leading to the electrical components within the ice-making and refrigeration module 200, specifically, electrical components such as the defrost heater, the fan 240, and various sensors.

[0098] Furthermore, in one embodiment of the present invention, the ice-making refrigeration module 200 is installed on the top wall of the ice-making chamber 130 and is close to the side wall where the terminal assembly 280 is set, so that the distance between the terminal assembly 280 and the wire outlet hole 270 is shortened, thereby reducing the length of the wiring harness connected to the terminal assembly 280.

[0099] See Figure 15As shown, the terminal assembly 280 includes a terminal box 281, a terminal 282 and a box cover 283, wherein the terminal box 281 is buried on the side wall of the ice-making chamber 130, the terminal 282 is installed in the terminal box 281, and the box cover 283 is connected to the terminal box 281 to seal the terminal box 281. The box cover 283 is provided with an inlet hole 284 for the wiring harness to pass through, so that the wiring harness led out of the outlet hole 270 enters the terminal box 281 through the inlet hole 284 and is connected to the terminal 282 for power supply.

[0100] In one embodiment of the present invention, a waterproof structure 285 is further provided on the top of the terminal box 281 to prevent condensation on the sidewall of the ice making chamber 130 from flowing into the terminal box 281. Specifically, the waterproof structure 285 is a waterproof edge inclined from the upper side of the terminal box 281. Of course, it is understood that the waterproof structure 285 is not limited to this.

[0101] A temperature sensor is provided in the ice making chamber 130 , and a through hole for routing the temperature sensor is provided on the terminal box 281 , thereby solving the problem of routing the temperature sensor.

[0102] The wiring terminal 282 includes a first connection end 2821 connected to the terminal box 281, and a second connection end 2822 connected to the wiring harness. The second connection end 2822 is located on the lower side of the first connection end 2821. The second connection end 2822 is set downward, which can prevent condensation in the terminal box 281 from flowing into the second connection end 2822, thereby avoiding the problem of short circuit in the wiring harness connected to the second connection end 2822.

[0103] The connection terminals 282 include strong current terminals and weak current terminals. A partition plate is protruding from the terminal box 281 to separate the strong current terminals from the weak current terminals to prevent the strong current terminals from causing signal interference to the weak current terminals.

[0104] The refrigeration housing 210 further includes a wire clamp 215 located at the lower side of the wire outlet hole 270 . The wire clamp 215 is used to constrain the wire harness led out of the wire outlet hole 270 to prevent a user from touching the wire harness.

[0105] Specifically, the wire fixing clamp 215 includes a pair of relatively arranged retaining edges 2151, and the retaining edges 2151 are formed by protruding outward from the side of the ice-making shell. Each of the wire fixing clamps 215 also includes a flange 2152 folded inward from one end of the retaining edge 2151 away from the ice-making shell, and the wire harness led out of the wire outlet hole 270 is constrained by the cooperation of the retaining edges 2151 and the flange 2152.

[0106] The wire inlet hole 284 can be a U-shaped groove formed downward from the upper end surface of the box cover 283, and the U-shaped groove is connected to the wire clamp 215 to facilitate connecting the wire harness led out of the wire outlet hole 270 to the wire inlet hole 284. Of course, it is understood that the structure of the wire inlet hole 284 is not limited to this.

[0107] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0108] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
