[0038] The present invention will be described in detail below in conjunction with 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 a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0039] It should be understood that the terms used herein, such as "upper", "lower", "inner", "front", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one component or feature relative to another component or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0040] The utility model provides a refrigeration device. It can be understood that the refrigeration device can be a refrigerator, a freezer, etc. Figure 1As shown, the refrigeration equipment includes a box body 100 and a door body for opening and closing the box body 100.

[0041] In one embodiment of the utility model, the ice-making chamber 130 can be arranged in the storage room, specifically, the ice-making chamber 130 can be arranged in the freezer 120, for example, a heat-insulating partition 140 is arranged in the freezer 120, and the ice-making chamber 130 is separated by the heat-insulating partition 140, wherein the ice-making chamber 130 can be a space enclosed by the inner liner of the freezer 120 and the heat-insulating partition 140, and a partition can be installed in the ice-making chamber 130 to separate the ice-making chamber 130 as needed, such as a partition can be installed in the ice-making chamber 130 to form an air path for cold air to flow, and a partition can also be installed to divide the space for installing components such as an evaporator. The door body can include a freezer door 122 that seals the freezer 120, and an ice-making door 131 that seals the ice-making chamber 130.

[0042] The refrigeration equipment also includes a refrigeration system for providing cold air to the refrigeration room, and the refrigeration system includes at least a compressor 150, a condenser, a capillary tube and an evaporator. A compressor compartment 151 is provided inside the refrigeration equipment to install the compressor 150. The evaporator may include a storage evaporator for supplying cold air to the storage room, and may also include an ice-making evaporator 230 for supplying cold air to the ice-making room 130. The storage evaporator and the ice-making evaporator 230 may share the compressor 150, that is, the refrigerant flowing out of the compressor 150 may selectively flow to the storage evaporator or the ice-making evaporator 230. Among them, the storage evaporator may also include a refrigeration evaporator 111 for supplying cold air to the refrigeration room and a freezing evaporator 121 for supplying cold air to the freezing room. The capillary tube 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, the refrigerant from the compressor first flows through the capillary tube corresponding to the evaporator and then is transported 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.

[0043] In one embodiment of the utility model, the refrigerant flowing out of the compressor 150 can flow directly to the freezing evaporator 121 and then return to the compressor 150, and can flow to the ice-making evaporator 230 first, enter the freezing evaporator 121 after passing through the ice-making evaporator 230, and then return to the compressor 150. In this way, the refrigerant provided by the compressor 150 is fully utilized.

[0044] The refrigeration system may include a refrigeration module installed in the refrigeration compartment, the refrigeration module being used to supply cold air to the refrigeration compartment. The refrigeration module may include a refrigeration housing forming an evaporator compartment, and an evaporator arranged in the evaporator compartment.

[0045] 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.

[0046] The refrigeration module may also include a defrost heating wire and a water receiving tray. The defrost heating wire is used to provide the evaporator with the heat required for defrosting. The water receiving tray may be located at the lower side of the evaporator and is used to collect and discharge the defrost water of the evaporator. The refrigeration module may also include a fan, which is used to guide the cold air of the evaporator to flow into the refrigeration compartment.

[0047] The refrigeration module of the utility model can be installed as an independent module at the supplier, which not only ensures the installation accuracy of the refrigeration module, 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.

[0048] See also Figures 2 to 19 As shown, in the specific embodiment provided by the utility model, 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 known that the left and right direction of the refrigeration device is the width direction, the front and rear direction of the refrigeration device is the depth direction, and the up and down direction of the refrigeration device is the height direction. For the convenience of description, the width direction of the refrigeration device is defined as the first direction, and the depth direction of the refrigeration device is defined as the second direction. The height direction of the refrigeration device is defined as the third direction.

[0049] The ice-making refrigeration module 200 includes a refrigeration housing 210, which is installed in the ice-making chamber 130. The refrigeration housing 210 is surrounded to form an evaporator chamber. The ice-making refrigeration module 200 also includes an ice-making evaporator 230 arranged in the evaporator chamber, and cold air is provided to the ice-making chamber through the ice-making evaporator 230. The ice-making chamber 130 in this embodiment can be independently arranged in the freezing chamber, and the ice-making machine 300 in the ice-making chamber 130 is supplied with cold by the independent ice-making refrigeration module 200. The ice cubes made by the ice-making machine 300 will not have the problem of cross-flavor, and there will be no problem of microorganisms in the storage room flowing into the ice-making chamber to cause bacteria to grow. Therefore, the ice-making machine 300 can make clean ice to ensure the food safety of users.

[0050] The refrigeration housing 210 is provided with a return air port 218 and an air outlet 217. It can be understood that the return air port 218 and the air outlet 217 allow the evaporator chamber to communicate with the ice-making chamber 130. The hot air in the ice-making chamber 130 enters the evaporator chamber through the return air port 218, and after heat exchange with the ice-making evaporator 230 to become cold air, enters the ice-making chamber 130 through the air outlet 217, thereby continuously providing cold air for the ice-making chamber 130.

[0051] In one embodiment of the utility model, the refrigeration housing 210 may include a first housing 211 and a second housing 212 connected to the first housing 211, and the first housing 211 and the second housing 212 are connected to form an evaporator chamber. Since the refrigeration housing 210 is arranged in a split body, it is convenient for processing and installation of the ice-making evaporator 230. In addition, the evaporator chamber formed by the first housing 211 and the second housing 212 can seal the ice-making evaporator installed inside, so when installing the ice-making refrigeration module 200, it is not necessary to seal the connection between the ice-making refrigeration module 200 and the ice-making chamber 130.

[0052] In one embodiment of the utility model, 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 up and down, the first shell 211 is connected to the ice-making chamber 130, and the second shell 212 is 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 is provided on the first shell 211, and a bayonet matched with the snap is provided on the second shell 212. Of course, it can be understood that the snap is not limited to one structure, and multiple snaps can also be provided on the first shell 211, so as to improve the stability of the connection between the first shell 211 and the second shell 212.

[0053] The second shell 212 can be configured as a box structure with a storage space, and the upper portion of the second shell 212 has an opening connected to the storage space, and the first shell 211 can be configured as a cover plate structure. After the first shell 211 and the second shell 212 are connected, the first shell 211 seals the opening of the second shell 212 to form a sealed evaporator chamber. Of course, it can be understood that the specific structures of the first shell 211 and the second shell 212 are not limited thereto.

[0054] 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.

[0055] 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 buckled to form the outlet hole 219 for the refrigerant pipe 260 to enter and exit. The outer side 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 utility model, 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 to prevent frost at the outlet hole 219.

[0056] The refrigeration housing 210 further includes a wire outlet hole 270, through which the wire harness in the ice-making refrigeration module 200 passes and is powered by the refrigeration device. Specifically, the wire outlet hole 270 includes an upper wire outlet hole section located in the first housing 211 and a lower wire outlet hole section located in the second housing 212, and a sealing rib 271 is protruded on the inner wall of the upper wire outlet hole section or / and the lower wire outlet hole section. After the first housing 211 and the second housing 212 are connected, the sealing rib 271 presses against the wire harness, thereby sealing the wire outlet hole 270.

[0057] In one embodiment of the utility model, the ice-making evaporator 230 includes a fin assembly 233 and a lower aluminum plate 232 connected to the lower side of the fin assembly 233. The ice-making evaporator may also include an upper aluminum plate 231 connected to the upper side of the fin assembly 233, and the upper aluminum plate 231 and the lower aluminum plate 232 may be fixed to the fin assembly 233 by riveting. The ice-making evaporator 230 may be installed in the first housing 211. If the ice-making evaporator 230 fails later, the second housing 212 may be removed, and the ice-making evaporator 230 may be easily repaired.

[0058] 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 utility model, the defrost heating wire is integrated in the ice-making evaporator 230. For example, embedding the defrost heating wire in the fin assembly 233 not only saves the space for placing the defrost heating wire in the evaporator chamber, but also increases the contact area between the defrost heating wire and the fin assembly 233, so that the ice-making evaporator 230 can be defrosted 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 up and down to prevent the defrost heating wire from being scratched during use.

[0059] The ice-making refrigeration module 200 also includes a water receiving pan installed in the evaporator room. In one embodiment of the utility model, 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 and then docked 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.

[0060] 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 refrigeration module 200 are also arranged to avoid the positions of the air outlet 217 and the return air port 218, so as to ensure smooth return and outlet of the evaporator chamber.

[0061] The ice-making refrigeration module 200 also includes a fan 240 disposed in the evaporator chamber. The fan 240 guides the cold air of 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.

[0062] The fan 240 is detachably connected to the refrigeration housing 210 or the water receiving tray 250. The refrigeration housing 210 is provided with a return air port 218 communicating with the ice-making chamber 130, and the ice-making evaporator 230 is located between the fan 240 and the return air port 218. The fan 240 is located on a side of the ice-making evaporator 230 away from the return air port 218. In one embodiment of the utility model, the fan 240 is installed on the first housing 211, the air outlet 217 and the return air port 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 port 218, so as to ensure that most of the hot air entering the evaporator chamber through the return air port 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 down the ice-making chamber 130.

[0063] In one embodiment of the utility model, the fan 240 is detachably connected to the first housing 211. The first housing 211 is provided with a fan mounting groove 241, and the fan 240 is detachably mounted in the fan mounting groove 241. Specifically, the fan 240 can be horizontally arranged in the fan mounting groove 241. The fan mounting groove 241 facilitates the 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. Further, a plurality of buckles for connecting the fan 240 are provided in the fan mounting groove 241, which ensures the reliability of the fan 240 being installed in the fan mounting groove 241. In addition, a shock-absorbing member abutting against the fan 240 is also provided in the fan mounting groove 241 to reduce the noise generated by the vibration of the fan 240.

[0064] See also Fig.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-making evaporator 230 and the fan 240, Fig.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 provided 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.

[0065] The refrigerant pipe 260 of the ice-making evaporator 230 has a pipe joint near the fan 240, which 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 the fan 240 from frosting.

[0066] In one embodiment of the utility model, 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 alternately arranged protrusions 2511 and grooves 2512. It can be understood that the first water receiving portion 251 and the second water receiving portion 252 are connected, and the first water receiving portion 251 below the ice-making evaporator 230 is a wave-shaped structure in which the protrusions 2511 are crests and the grooves 2512 are troughs. The grooves 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, a gap is left 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 utility model 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 room.

[0067] In one embodiment of the utility model, 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, the ice-making evaporator 230 and the fan 240 are arranged in the evaporator chamber along a second direction, the protrusion 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 direction and the second direction, and can 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 protrusion 2511 in contact with the hot air.

[0068] Furthermore, the second water receiving portion 252 is configured as a plane, thereby leaving a sufficient air suction distance for the fan 240. In one embodiment of the utility model, the fan 240 is tilted along the second direction at the top of the evaporator chamber, the side of the fan 240 close to the ice-making evaporator 230 is higher than the side away from the ice-making evaporator 230, and the second water receiving portion 252 is a plane with the same tilt direction as the fan 240, which further increases the air suction distance of the fan 240 and improves the wind guiding effect of the fan 240.

[0069] In one embodiment of the utility model, the refrigeration device includes a drain pipe 255, the housing 100 is provided with a drain port 170 connected to the drain pipe 255, and 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 inclined along the second direction, and the side of the first water receiving portion 251 close to the second water receiving portion 252 is lower than the side of the first water receiving portion 251 away from the second water receiving portion 252, so that the water collected by the groove portion 2512 on the first water receiving portion 251 flows toward the second water receiving portion 252, and flows into the drain pipe 255 of the refrigeration device through the drain nozzle 253 on the second water receiving portion 252, so as to achieve rapid discharge of defrost water.

[0070] 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. The side of the second water receiving portion 252 close to the first water receiving portion 251 is higher than the side away from the first water receiving portion 251, and the drain nozzle 253 is disposed at the lowest side of the second water receiving portion 252, so as to ensure that the defrost water flows into the drain nozzle 253 after flowing into the second water receiving portion 252, and finally enters the drain pipe 255.

[0071] Furthermore, an aluminum foil heating wire is installed near the drain nozzle 253 of the second water receiving portion 252, so as to avoid ice blockage of the drain nozzle 253 and ensure smooth discharge of defrost water. Since the second water receiving portion 252 is a plane, it is very convenient to lay the aluminum foil heating wire. Of course, the selection of the heating wire at the drain nozzle 253 is not limited to the aluminum foil heating wire.

[0072] The ice-making refrigeration module 200 further includes a windshield component 254 disposed between the ice-making evaporator 230 and the water receiving tray 250. The windshield component 254 can be disposed or connected to the ice-making evaporator 230, or can be disposed or connected to the water receiving tray 254. The windshield component 254 is used to shield a portion of the gap between the ice-making evaporator 230 and the water receiving tray 250. The windshield component 254 can block most of the hot air entering the evaporator room from flowing through the gap between the ice-making evaporator 230 and the water receiving tray 250 without affecting the flow of defrosting water in the water receiving tray 250, so that most of the hot air entering the evaporator room is cooled by the ice-making evaporator 230 and then guided by the fan 240 to flow into the ice-making chamber 130, thereby ensuring the cold air supply to the ice-making chamber 130.

[0073] In one embodiment of the present invention, refer to Fig.10 and Fig.14As shown, the wind shielding component 254 is arranged at the lower end of the ice-making evaporator 230. Specifically, the wind shielding component 253 is a convex rib protruding from the lower end surface of the lower aluminum plate 232 toward the water receiving tray 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 tray 250. The convex rib covers part of the gap between the ice-making evaporator 230 and the water receiving tray 250 to prevent the hot air entering the evaporator room from directly flowing through the gap between the ice-making evaporator 230 and the water receiving tray 250. Most of the hot air entering the evaporator room through the return air port 218 exchanges heat 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 and at the same time does not affect the flow of defrost water in the water receiving tray 250.

[0074] In another embodiment of the present invention, refer to Fig.18 and Fig.19 As shown, the wind shielding member 254 is disposed on the water receiving tray 250. Specifically, the wind shielding member 254 is a convex rib protruding from the upper end surface of the water receiving tray 250. The convex rib can be protruding from the upper end surface of the water receiving tray 250 toward the ice-making evaporator 230. Of course, it can be understood that the arrangement of the wind shielding member 254 is not limited to this.

[0075] See also Fig.14 As shown, the wind shielding member 254 is a plurality of convex ribs arranged at intervals along the first direction, each convex rib being located in one of the grooves 2512, and the convex ribs being arranged corresponding to the grooves 2512, and being able to effectively shield a portion of the gap between the lower aluminum plate 232 and the groove 2512 of the water receiving tray 250, thereby preventing most of the hot air entering the evaporator room from directly flowing through the gap between the ice-making evaporator 230 and the water receiving tray 250, and allowing most of the hot air entering the evaporator room through the return air port 218 to exchange heat with the ice-making evaporator 230 before flowing through the fan 240. In addition, the height of the convex rib is less than the distance between the lower aluminum plate 232 and the bottom of the groove 2512, so that the arrangement of the convex rib does not affect the flow of defrosting water in the water receiving tray 250.

[0076] The wind shielding member 254 is a plurality of rows of convex ribs spaced apart along the second direction, which further ensures 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 .

[0077] Furthermore, the wind shield component 254 is made of a heat-conducting material. In the present embodiment, the defrost heating wire is integrated in the ice-making evaporator 230. When the ice-making evaporator 230 is defrosting, 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.

[0078] In one embodiment of the utility model, the ice-making evaporator 230 is tilted in the evaporator chamber. When the ice-making evaporator 230 defrosts, the tilted setting 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.

[0079] 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 frosting in the evaporator chamber.

[0080] 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 outer periphery of the water receiving tray 250, and the second shell 212 is provided to fit the outer periphery of the heat-insulating member 290. The heat-insulating member 290 can be provided in a shape with the bottom wall of the water receiving tray 250 and the water retaining wall 256. The heat-insulating member 290 can be a material 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 heat-insulating member 290 can be set to an ultra-thin EPS foam board of 5 mm. The thickness of the foam board at different positions can be set to be different.

[0081] 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 room are compactly arranged, further reducing the overall size of the ice-making refrigeration module 200.

[0082] In this embodiment, the refrigeration device includes an inner tank and a hanger 180 connected to the inner tank, 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 connected or indirectly connected. Specifically, the ice-making refrigeration module 200 is installed on the top of the freezer compartment 120, and the hanger 180 is provided on the top of the inner tank 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 means of a sliding connection. The operation is simple and convenient, and the installation time is saved. Figure 5As shown, the hanger 180 has a slideway 181 extending along the axial direction of the drain port 170. The axial direction of the drain port 170 can be understood as a direction perpendicular to the imaginary plane where the drain port 170 is located. The refrigeration housing 210 is provided with a guide rib 214 that cooperates with the slideway 181. Specifically, the guide rib 214 can be set on the first housing 211. Through the cooperation between the guide rib 214 and the slideway 181, the ice-making refrigeration module 200 is reliably connected to the hanger 180. Of course, the way in which the ice-making refrigeration module 200 is installed on the top of the freezing chamber 120 is not limited to this. For example, it can also be installed by sliding along the axial direction of the drain port 170 in the first half of the stroke, and rotating and fixing in the second half.

[0083] In one embodiment of the present invention, the drain port 170 is disposed on a side wall of the inner container 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 arranged at intervals along the first direction; the guide ribs 214 include a pair of guide ribs 214 arranged opposite to each other 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 arranged at intervals 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, thereby avoiding 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.

[0084] In one embodiment of the utility model, 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.

[0085] A plurality of threaded holes are also provided on the refrigeration shell 210. 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.

[0086] In one embodiment of the utility model, the refrigerant pipe 260 of the ice-making evaporator 230 passes through the outlet hole 219 and passes into the interchamber air duct to be connected with other refrigerant pipes of the refrigeration system, or enters the compressor chamber 151 through the interchamber air duct to be connected with other refrigerant pipes of the refrigeration system.

[0087] 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 and other refrigerant pipes of the refrigeration system can be connected by welding.

[0088] During the installation process, the ice-making refrigeration module 200 can be first installed on the top of the ice-making chamber 130, and then the refrigerant pipe 260 of the ice-making refrigeration module 200 is welded to other refrigerant pipes in the compartment air duct. After welding, the air duct cover 160 is installed. Since there is ample space for welding, the installation difficulty for workers is reduced and the installation time is reduced.

[0089] In the utility model, 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, but are connected in the spacious compartment air duct or compressor chamber 151, thereby avoiding the risk of damage to the pipe joints after bending, which may increase the scrap rate of the refrigeration equipment.

[0090] Specifically, the refrigeration housing 210 is provided with a pipe outlet 213 on one side close to the air duct cover 160, and the pipe outlet hole 219 is provided in the pipe outlet 213. The air duct cover 160 is provided with a avoidance groove 161 for the pipe outlet 213 to pass through to the air duct of the compartment, and a sealing component, such as foam, is provided between the pipe outlet 213 and the avoidance groove 161, so as to seal the avoidance groove 161 and prevent frost from forming at the avoidance groove 161.

[0091] 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 part 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 along the shape of the bottom side surface of the outlet pipe part 213 to align with the outlet pipe part 213. Therefore, the avoidance groove 161 of the air duct cover 160 of this embodiment has a self-introduction function. Furthermore, the width of the slot opening of the avoidance slot 161 may be set to be greater than or equal to the width of the slot bottom of the avoidance slot, which is more conducive to installing the air duct cover plate 160 .

[0092] The ice-making refrigeration module 200 further includes an insulation tube sleeved on 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 arranged at a certain safety distance from the welding point between the refrigerant tube 260 and other refrigerant tubes.

[0093] 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 in the compartment air duct. The connection of the refrigerant pipe 260 is specifically described below by taking the ice-making chamber 130 being arranged in the freezing chamber 120 as a specific mode. Of course, the ice-making chamber 130 is not limited to being arranged in the freezing chamber 120.

[0094] In this embodiment, the storage evaporator is specifically a freezing evaporator, and the refrigeration air inlet pipe is specifically a freezing air inlet pipe connected to the freezing evaporator. The ice making air inlet pipe 263 of the ice making evaporator 230 is connected to the ice making capillary tube, and the ice making return air pipe 262 is connected to the freezing air inlet pipe of the freezing evaporator 121, that is, the refrigerant from the compressor 150 partially enters the ice making capillary tube after passing through the condenser, and then flows through the ice making evaporator 230 and the freezing evaporator 121 in sequence and then returns to the compressor 150. The connection in this embodiment can be a direct connection or an indirect connection.

[0095] Specifically, the refrigeration system includes a first air inlet pipe located in the compartment air duct, and 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, and 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 in the compartment air duct to achieve 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 is also connected to the refrigeration air inlet pipe in the compartment air duct, and the compartment air duct is relatively spacious, which is convenient for workers to weld and install, reducing the difficulty of installing the refrigerant pipe and saving installation time.

[0096] Specifically, the specific direction of the refrigerant pipe 260 in the evaporator room after being led out from the pipe outlet hole 219 is: the refrigerant pipe 260 goes downward into the freezer compartment air duct, the ice-making return air pipe 262 and the refrigeration air inlet pipe of the refrigeration evaporator are welded in the freezer compartment, the first air inlet pipe and the second air inlet pipe are welded in the freezer compartment, and then the refrigeration air duct cover 160 is installed, so that workers have ample space when welding, reducing the difficulty of installation.

[0097] In one embodiment of the utility model, a compression pipe clamp and a shock-absorbing member 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-absorbing member 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.

[0098] In another embodiment of the utility model, a pipe clamp, a pipe whole, and a shock-absorbing member connected to the pipe clamp and / or the pipe whole are further provided in the compartment air duct. The refrigerated air inlet pipe is fixed to the back of the box body 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 known that the refrigerant pipe 260 includes an ice-making air inlet pipe 263 and an ice-making air return pipe 262. The refrigerated air inlet pipe, the first air inlet pipe, the ice-making air return pipe 262, and the second air inlet pipe in the compartment air duct are all fixed to the box body 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-absorbing member.

[0099] In one embodiment of the utility model, the refrigeration device further includes a terminal block assembly 280 embedded in the ice-making chamber 130, and the terminal block assembly 280 is used to connect to the wire harness led out of the outlet hole 270 and supply power, thereby solving the problem of wiring in the ice-making chamber 130, and also avoiding the problem of condensation causing short circuit when the terminal block assembly 280 is placed at the back of the refrigeration device. It can be understood that the wire harness led out of the outlet hole 270 is a wire harness led out of the electrical components in the ice-making refrigeration module 200, specifically, the electrical components such as defrosting heating wire, fan 240, and various sensors.

[0100] Furthermore, in one embodiment of the utility model, 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.

[0101] See also Fig.15 As 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 in the side wall of the ice-making chamber 130, the terminal 282 is installed in the terminal box 281, the box cover 283 is connected to the terminal box 281 to seal the terminal box 281, and the box cover 283 is provided with a wire entry hole 284 for the wiring harness to pass through, so that the wiring harness led out of the wire outlet hole 270 enters the terminal box 281 through the wire entry hole 284 and is connected to the terminal 282 for power supply.

[0102] 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 side wall 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 can be understood that the waterproof structure 285 is not limited to this.

[0103] The ice making chamber 130 is provided with a temperature sensor, and the terminal box 281 is provided with a through hole for routing the temperature sensor, thereby solving the problem of routing the temperature sensor.

[0104] 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 at 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.

[0105] The connection terminals 282 include strong current terminals and weak current terminals. A partition plate is protruding inside the terminal box 281. The partition plate is used 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.

[0106] The refrigeration housing 210 further includes a wire clamp 215 located at the lower side of the wire outlet hole 270 , and 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.

[0107] Specifically, the wire fixing clamp 215 includes a pair of relatively arranged guard edges 2151, and the guard 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 guard 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 guard edges 2151 and the flange 2152.

[0108] The wire inlet hole 284 may be a U-shaped groove formed by being recessed 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 understandable that the structure of the wire inlet hole 284 is not limited thereto.

[0109] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description 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 mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0110] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model.
