[0106] Please refer to FIG. 1-2, FIG. 30 and FIG. 31, a refrigerator of a preferred embodiment of the present application comprises: a cabinet, a refrigeration cycle pipeline 200 and an ice making chamber assembly 300.

[0107] The cabinet comprises an outer shell and a tank 100 arranged inside the outer shell, a tank wall of the tank 100 is provided with a first opening 110, and the tank 100 has a tank opening for mounting a cabinet door.

[0108] The mounting space is formed between the outer shell and the tank 100 for mounting other components of the refrigerator and forming a foamed thermal insulation layer. The inside of the tank 100 forms a refrigeration chamber, that is, a refrigeration chamber, a variable temperature chamber or a freezing chamber.

[0109] The first opening 110 is a hole formed on the wall of the tank 100, and the first opening 110 communicates with the foamed thermal insulation layer, in other words, the first opening 110 is not used to arrange the cabinet door.

[0110] The cabinet door is arranged at the tank opening of the tank 100, and by controlling the opening and closing of the cabinet door, the opening and closing of the refrigeration chamber can be controlled.

[0111] The refrigeration cycle pipeline 200 is arranged between the shell and the box body 100, and the refrigeration cycle pipeline 200 comprises a direct cooling section 210 extending into the box body 100 from the first opening 110.

[0112] The refrigerator has a refrigeration cycle system for cooling the box body 100, which generally comprises components such as a compressor, a condenser, a drying filter, a capillary tube, and an evaporator connected by the refrigeration cycle pipeline 200, and the working structure of the refrigeration cycle system comprises a compression process, a condensation process, a throttling process, and an evaporation process. Specifically, the compression process is as follows: after the power cord of the refrigerator is plugged in and the contacts of the temperature controller are connected, the compressor starts to work, the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor, and then discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas is cooled by the condenser, the temperature continuously decreases, and gradually cooled into a normal-temperature and high-pressure saturated vapor, and further cooled into a saturated liquid, the temperature no longer decreases, and the pressure of the refrigerant in the entire condensation process is almost unchanged. The throttling process is as follows: the condensed refrigerant saturated liquid flows into the capillary tube after filtering out water and impurities by the drying filter, and is throttled and depressurized by the capillary tube, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. The evaporation process is as follows: the normal-temperature and low-pressure wet vapor enters the evaporator, starts to absorb heat to vaporize, reduces the temperature of the evaporator and its surroundings, so that the refrigeration chamber achieves refrigeration, and the refrigerant becomes a low-temperature and low-pressure gas. The refrigerant from the evaporator returns to the compressor again to repeat the above process, and through the state change of the refrigerant, energy conversion is carried out to transfer the heat in the refrigerator to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator. When the evaporator is arranged on the cavity wall of the refrigeration chamber, it is a direct cooling refrigerator; when the evaporator is arranged in the air duct of the refrigerator, it is a forced air cooling refrigerator. The structure and operation principle of the above-mentioned refrigerator refrigeration cycle system are all prior art, and will not be described here.

[0113] The direct cooling section 210 is part of the refrigeration cycle pipeline 200, and for the convenience of description, the part extending into the inside of the box body 100 is referred to as the direct cooling section 210.

[0114] Since the refrigerator of the embodiment has the first opening 110 provided on the wall of the box body 100 for the direct cooling section 210 of the refrigeration cycle pipeline 200 to pass through, the direct cooling section 210 of the refrigeration cycle pipeline 200 can extend into the inside of the box body from the first opening 110. In the case where the first opening 110 is not provided on the wall of the box body 100, the direct cooling section 210 can extend into the inside of the box body 100 from the mouth of the box body 100 corresponding to the door of the refrigerator.

[0115] Referring to FIG. 1, FIG. 4 and FIG. 5, the ice-making compartment assembly 300 includes a first housing 310 for defining an ice-making compartment 350 and an ice-making unit 360 disposed in the ice-making compartment 350, the ice-making unit 360 including an ice tray 320, the first housing 310 being detachably installed in the box body 100, an outer surface of the first housing 310 being provided with a second opening 311 in communication with the ice-making compartment 350, the direct cooling section 210 penetrating through the second opening 311 and at least partially contacting the ice tray 320.

[0116] The ice-making unit 360 is configured to produce ice cubes, and the first housing 310 is configured to define the ice-making compartment 350, which can be defined by the first housing 310 alone or by the first housing 310 in cooperation with other structures, the ice-making compartment 350 being separated from the refrigeration compartment.

[0117] Generally, since the direct cooling section 210 is capable of cooling the ice-making compartment 350, the ice-making compartment assembly 300 can be disposed in a refrigeration compartment or a freezing compartment.

[0118] Referring to FIG. 5 and FIG. 6, the ice-making unit 360 includes the ice tray 320 and a water pipe configured to supply water to the ice tray 320, and the direct cooling section 210 is configured to exchange heat with the ice tray 320. The ice-making unit 360 further includes a driving device configured to drive the ice tray 320 to flip over after water in the ice tray 320 is frozen, so that an opening of the ice tray 320 faces downward and ice cubes are removed. An ice storage box is generally disposed below the ice tray 320, and ice cubes falling from the ice tray 320 are stored in the ice storage box, and the direct cooling section 210 exchanges heat with air in the ice-making compartment 350, so as to ensure a low-temperature state in the ice storage box. Thereafter, the ice tray 320 is reset, the water pipe supplies water to the ice tray 320, and the ice-making process is repeated.

[0119] In the embodiment, the ice-making compartment assembly 300 does not have the direct cooling section 210, and the direct cooling section 210 of the refrigeration cycle pipeline 200 provides cold energy to the ice-making compartment assembly 300. The refrigeration cycle pipeline 200 is configured to cool the box body 100 and the ice-making compartment 350 at the same time.

[0120] Referring to FIG. 1 and FIG. 4, the second opening 311 is provided to facilitate the direct-cooling section 210 to enter and exit the first housing 310, i.e., the ice-making chamber 350, when the ice-making chamber assembly 300 is assembled or disassembled. When the ice-making chamber assembly 300 is assembled, the direct-cooling section 210 directly contacts the ice cube tray 320, and the direct-cooling section 210 directly exchanges heat with the ice cube tray 320 to ensure the cooling effect of the ice cube tray 320 and the ice-making efficiency.

[0121] When the ice-making chamber assembly 300 is assembled, the direct-cooling section 210 enters the ice-making chamber 350 through the second opening 311 until the first housing 310 reaches the installation position in the box body 100, and at least a portion of the direct-cooling section 210 can contact the ice cube tray 320. When the ice-making chamber assembly 300 is disassembled, the first housing 310 moves out of the box body 100 until the direct-cooling section 210 is completely separated from the second opening 311.

[0122] In other words, when the ice-making chamber assembly 300 is assembled, the first housing 310 is connected to the inner wall of the box body 100 after the direct-cooling section 210 enters the ice-making chamber 350. Similarly, when the ice-making chamber assembly 300 is disassembled, the connection between the first housing 310 and the box body 100 is released, and then the direct-cooling section 210 is pulled out of the second opening 311.

[0123] Through such a structure, the ice-making chamber assembly 300 is assembled on the direct-cooling section 210, so that the refrigeration cycle pipeline 200 can be pre-buried in the box body 100 during the refrigerator manufacturing process, and a portion of the refrigeration cycle pipeline 200 extends into the box body 100 to form the direct-cooling section 210. Then, the second opening 311 of the ice-making chamber assembly 300 that is assembled as a whole is aligned with the direct-cooling section 210, the direct-cooling section 210 is inserted into the ice-making chamber assembly 300, and then the first housing 310 and the box body 100 are connected to achieve the modular assembly of the ice-making chamber assembly 300.

[0124] When the ice-making chamber assembly 300 needs to be maintained after being sold, the connection between the first housing 310 and the box body 100 is released, and the first housing 310 moves out of the box body 100 until the direct-cooling section 210 is completely separated from the second opening 311. The ice-making chamber assembly 300 is still disassembled as a whole to achieve the modular disassembly of the ice-making chamber assembly 300.

[0125] After the ice-making chamber assembly 300 is maintained, the ice-making chamber assembly 300 can still be installed on the box body 100 according to the installation method during the refrigerator manufacturing process.

[0126] Therefore, the ice-making chamber assembly 300 can be modularly disassembled in the refrigerator manufacturing process and the after-sales maintenance process, without disassembling each part of the ice-making chamber assembly 300 one by one, reducing the difficulty of disassembly and simplifying the operation of the staff.

[0127] In the related art, there are two structures of the ice-making chamber assembly and two corresponding installation methods.

[0128] One of the ice-making chamber assemblies does not have a refrigeration pipe. In the refrigerator manufacturing process, the refrigeration cycle pipeline embedded in the tank is a complete passage, similar to the refrigeration cycle pipeline in the present embodiment, a part of which extends into the tank to form a direct cooling section. For this ice-making chamber assembly, whether in the refrigerator manufacturing process or in the after-sales maintenance process, the disassembly of the ice-making chamber assembly requires disassembling each part one by one, and the ice-making chamber assembly is complicated to disassemble.

[0129] Another ice-making chamber assembly has a refrigeration pipe. In the refrigerator manufacturing process, the refrigeration cycle pipeline embedded in the tank is a broken circuit, and the end of the broken circuit extends into the tank. After the shell of the ice-making chamber assembly is connected to the tank, the refrigeration pipe and the broken end of the refrigeration cycle pipeline are welded together to make the refrigeration pipe and the refrigeration cycle pipeline communicate. In this case, when the ice-making chamber assembly needs to be maintained in the after-sales stage, it is not possible to separate the refrigeration pipe and the refrigeration cycle pipeline without damaging the parts. In this case, the ice-making chamber assembly can only be disassembled by disassembling each part one by one, and each part needs to be assembled one by one when the ice-making chamber assembly is assembled. Therefore, although this ice-making chamber assembly can be modularly installed in the refrigerator manufacturing stage, it still has the problem of complicated disassembly of the ice-making chamber assembly in the after-sales stage.

[0130] The refrigerator of the present embodiment can be modularly disassembled in the refrigerator manufacturing stage and the after-sales maintenance stage, without disassembling each part of the ice-making chamber assembly 300 one by one, and without welding the direct cooling section 210 of some ice-making chamber assemblies 300 to the refrigeration cycle pipeline 200 in the prior art, reducing the manufacturing process, reducing the difficulty of disassembly, and simplifying the operation of the staff.

[0131] In some embodiments, referring to FIGS. 5-6, the ice-making chamber assembly 300 further includes a pressing plate 400, which is arranged inside the ice-making chamber 350, connected to the ice-making unit 360, arranged on the side of the direct cooling section 210 away from the ice tray 320, and used to abut the direct cooling section 210 against the ice tray 320.

[0132] The pressing plate 400 can make the direct-cooling section 210 abut against the ice cube tray 320, so as to ensure that the direct-cooling section 210 can continuously contact the ice cube tray 320 directly.

[0133] As shown in FIG. 6, the direct-cooling section 210 is usually arranged at the bottom of the ice cube tray 320, and the pressing plate 400 is arranged below the direct-cooling section 210.

[0134] In the present embodiment, the ice-making chamber 350 can be completely defined by the first shell 310, or can be defined by the first shell 310 and other structures together, and in these two cases, the connection mode of the pressing plate 400 is different.

[0135] When the ice-making chamber 350 is defined by the first shell 310 and other structures together, the first shell 310 can be in an open state.

[0136] In this case, as shown in FIGS. 7-9, the pressing plate 400 is provided with a first connecting hole 420 penetrating through the pressing plate 400, and the ice cube tray 320 is provided with a second connecting hole 322 corresponding to the first connecting hole 420; the ice-making chamber assembly 300 further comprises a connecting piece 323, which is connected to the second connecting hole 322 through the first connecting hole 420.

[0137] In the present embodiment, the connecting piece 323 is a bolt, and the first connecting hole 420 and the second connecting hole 322 are bolt holes, and the bolt is connected to the first connecting hole 420 and the second connecting hole 322, so as to form the bolt connection between the pressing plate 400 and the ice cube tray 320. After the bolt connection is completed, the pressing plate 400 makes the direct-cooling section 210 abut against the ice cube tray 320.

[0138] Since the first shell 310 in this case can be in an open state, sufficient space can be provided for the worker to hold the pressing plate 400 and use a tool to screw the bolt thereon.

[0139] In this case, as shown in FIGS. 10-13, the ice-making chamber assembly 300 further comprises a second shell 340, the first shell 310 and the second shell 340 are detachably connected, the first shell 310 and the second shell 340 jointly define the ice-making chamber 350, the first shell 310 is detachably connected to the inner wall of the box body 100, and the ice-making unit 360 is arranged on the first shell 310.

[0140] The first shell 310 and the second shell 340 are both part of the entire shell of the ice-making chamber 350, but when the ice-making chamber assembly 300 is installed, the ice-making unit 360 is first installed on the first shell 310, then the first shell 310 is installed on the inner wall of the box body 100, the bolts of the pressing plate 400 are tightened, and then the second shell 340 is installed on the first shell 310, thereby completing the installation of the entire shell of the ice-making chamber assembly 300.

[0141] When the ice-making chamber assembly 300 is disassembled, the second shell 340 is first dismounted from the first shell 310, so that the first shell 310 is in an open state, then the bolts of the pressing plate 400 are loosened, the pressing of the direct-cooling section 210 is released, and then the first shell 310 and the ice-making unit 360 are dismounted from the box body 100 together.

[0142] The first shell 310 includes a half-shell body 313 and a back plate 314 connected to each other, the half-shell body 313, the back plate 314 and the second shell 340 jointly define the ice-making chamber 350, and the back plate 314 is detachably connected to the inner wall of the box body 100.

[0143] The half-shell body 313 at least serves as a top and a side wall close to the inner wall of the box body 100 of the ice-making chamber 350, the back plate 314 at least serves as a rear wall of the ice-making chamber 350, the back plate 314 is connected to the box body 100, and the half-shell body 313 is also connected to the box body 100.

[0144] In some embodiments, the ice-making chamber assembly 300 is arranged at a corner on the top of the box body 100, and since the first shell 310 is composed of the half-shell body 313 and the back plate 314, the back plate of the ice-making chamber assembly 300, that is, the back plate 314, can be arranged corresponding to the back plate of the box body 100, and the side wall of the ice-making chamber assembly 300, that is, a side wall on the half-shell body 313, can be arranged corresponding to the side wall of the box body 100.

[0145] The half-shell body 313 can serve as a side wall and a top wall of the ice-making chamber assembly 300, the half-shell body 313 is connected to the back plate 314 to form the first shell 310 in an open state. The second shell 340 can serve as a side wall and a bottom wall of the ice-making chamber assembly 300, and the half-shell body 313, the back plate 314 and the second shell 340 form the outer wall of the ice-making chamber assembly 300.

[0146] In some embodiments, referring to FIGS. 12 and 14-15, the refrigerator further comprises a fixing plate 120 arranged between the liner 100 and the outer shell, the fixing plate 120 being provided with a first clamping groove 121 opening towards the liner 100.

[0147] The liner 100 is provided with a second through hole corresponding to the first clamping groove 121, and the first shell 310 is provided with a first clamping buckle 312 which passes through the second through hole and clamps with the first clamping groove 121.

[0148] The fixing plate 120 is arranged between the liner 100 and the outer shell before the first shell 310 is installed, and the fixing plate 120 can be fixed on the outer wall of the liner 100 by a connecting member such as a screw, and the fixing plate 120 is equivalent to being embedded in the foaming layer between the liner 100 and the outer shell.

[0149] The first clamping buckle 312 is arranged on the half-shell body 313, and the first clamping buckle 312 clamps with the first clamping groove 121 to achieve installation of the half-shell body 313 on the inner wall of the liner 100. The back plate 314 is also installed on the inner wall of the liner 100. When the ice-making unit 360 is arranged on the first shell 310, the first shell 310 has a certain load-bearing capacity because the half-shell body 313 and the back plate 314 are both connected with the inner wall of the liner 100, so that the ice-making chamber assembly 300 is stably arranged in the liner 100 through the first shell 310.

[0150] Referring to FIGS. 11-12, in some embodiments, the liner 100 further comprises a junction box arranged on the side wall or the back wall of the liner 100, the first shell 310 is provided with a fourth opening 317, the junction box passes through the fourth opening 317 and enters the ice-making chamber 350, and the top wall of the junction box abuts against at least a part of the edge of the fourth opening 317 to support the first shell 310. The junction box is pre-installed on the liner 100 before the ice-making chamber assembly 300 is installed. By arranging the fourth opening 317, at least a part of the junction box extends into the ice-making chamber 350 and supports the first shell 310.

[0151] In the present embodiment, the junction box is arranged on the side wall of the liner 100, and the fourth opening 317 is arranged on the half-shell body 313.

[0152] The position of the junction box is arranged in this way, so that the junction box, the fixing plate 120 and the back plate 314 jointly support the first shell 310, thereby enabling the first shell 310 to be more stably mounted on the tank 100.

[0153] In some embodiments, referring to FIGS. 12 and 16, a support portion 130 is arranged on an inner wall of the tank 100, on a side of the tank 100 facing the ice-making compartment assembly 300. A fifth opening 318 is arranged on the first shell 310, and the support portion 130 passes through the fifth opening 318 into the ice-making compartment 350. The top wall of the support portion 130 abuts at least a portion of the edge of the fifth opening 318, so that the support portion 130 supports the first shell 310.

[0154] In this embodiment, the support portion 130 is a protrusion on the inner wall of the tank 100, and the support portion 130 supports the first shell 310 by being inserted into the fifth opening 318.

[0155] In this embodiment, the support portion 130 is arranged on a rear wall of the tank 100, on a side of the tank 100 facing the ice-making compartment assembly 300, and the fifth opening 318 is arranged on the back plate 314. In some embodiments, the support portion 130 is arranged on a side wall of the tank 100, on a side of the tank 100 facing the ice-making compartment assembly 300, and the fifth opening 318 is arranged on the half-shell body 313.

[0156] In this way, the support portion 130, the junction box and the fixing plate 120 can all support the first shell 310, and share the gravity of the ice-making compartment assembly 300, thereby ensuring that the first shell 310 is more stably mounted on the tank 100, and that the ice-making compartment assembly 300 is stably mounted in the tank 100.

[0157] Referring to FIGS. 12-13 and 17-19, the edge of the first shell 310 is provided with a first rail groove 315 that is open in the lateral direction, and the edge of the second shell 340 is provided with a first sliding rail 341 that is slidably connected to the first rail groove 315. The bottom of the first sliding rail 341 slidably abuts the groove wall of the first rail groove 315, so that the first rail groove 315 supports the first sliding rail 341.

[0158] When the second shell 340 is mounted on the first shell 310, the first sliding rail 341 is aligned with the first rail groove 315, and the second shell 340 is slid along the first rail groove 315 towards the back plate 314, so that the second shell 340 is mounted on the first shell 310.

[0159] Since the bottom of the first slide rail 341 is arranged to abut against the slot wall of the first track slot 315, the first slide rail 341 and the first track slot 315 cooperate to support the second casing 340, so that the second casing 340 is kept connected with the first casing 310. In the present embodiment, no structure such as the ice making unit 360 is installed on the second casing 340, so that the requirement for bearing capacity is not high, and thus the second casing 340 can be stably installed in the tank 100 even if it is not directly connected with the tank 100.

[0160] The edge of the second casing 340 is further provided with a second track slot 342, and the edge of the first casing 310 is provided with a second slide rail 316 which is slidably connected with the second track slot 342. The respective extension directions of the first slide rail 341 and the second slide rail 316 are parallel to each other and point to the tank opening.

[0161] The second track slot 342 and the second slide rail 316 can also play a role in assisting the installation of the second casing 340 on the first casing 310, so as to facilitate the connection between the first casing 310 and the second casing 340.

[0162] In the present embodiment, the second casing 340 comprises an inner casing wall 343 and an outer casing wall 344, and the inner casing wall 343 and the outer casing wall 344 form the hollow structure of the second casing 340.

[0163] The hollow structure formed by the inner casing wall 343 and the outer casing wall 344 is used to arrange a foaming layer. In this way, even if there is a temperature difference between the ice making chamber 350 and the refrigeration cavity in the tank 100, since the foaming layer is arranged between the inner casing wall 343 and the outer casing wall 344, the heat exchange between the inside and outside of the ice making chamber 350 can be blocked, so as to ensure the temperature stability in the ice making chamber 350.

[0164] The ice making chamber assembly 300 in the present embodiment is arranged at one corner of the tank 100, and thus only the second casing 340 which contacts the air inside the refrigeration cavity needs to be provided with the foaming layer, and the first casing 310 which directly contacts the tank 100 can not be provided with the foaming layer, so that the use of the foaming layer can be reduced.

[0165] At least one connection between the inner casing wall 343 and the outer casing wall 344 is provided with an anti-overflow part. The arrangement of the anti-overflow part can prevent the foaming liquid from flowing out of the second casing 340. In the present embodiment, the first track slot 315, the first slide rail 341, the second track slot 342 and the second slide rail 316 jointly form at least a part of the anti-overflow part.

[0166] The first track groove 315 and the second track groove 342 are arranged adjacently, and after the second housing 340 is installed on the first housing 310, the first track groove 315, the first slide rail 341, the second track groove 342 and the second slide rail 316 form a labyrinth structure, thereby preventing the foaming liquid from overflowing. That is, the first track groove 315 and the first slide rail 341 not only facilitate the installation of the second housing 340, but also support the second housing 340 and prevent the foaming liquid from overflowing as part of the anti-overflowing part.

[0167] When the ice-making chamber 350 is completely defined by the first housing 310, that is, the first housing 310 at least has a top surface, a side surface, a bottom surface and a back surface, it is difficult to connect the pressing plate 400 by means of bolts and the like, because the pressing plate 400 is located inside the ice-making chamber 350, and it is difficult for the worker to put his hand and tool into the ice-making chamber 350 to work. To solve this problem, referring to FIGS. 6 and 20, the refrigerator further comprises a control mechanism 500 arranged inside the ice-making chamber 350, the control mechanism 500 being connected to the pressing plate 400 and driving the pressing plate 400 to switch between a first state and a second state; when the pressing plate 400 is in the first state, the pressing plate 400 and the ice tray 320 form a first channel 330 for the direct-cooling section 210 to enter and exit, and when the pressing plate 400 is in the second state, the pressing plate 400 abuts the direct-cooling section 210 against the ice tray 320.

[0168] The pressing plate 400 abuts the direct-cooling section 210 against the ice tray 320, so that the direct-cooling section 210 maintains a contact state with the ice tray 320, ensures that the direct-cooling section 210 directly cools the ice tray 320, and thus guarantees the ice-making efficiency of the ice tray 320.

[0169] It is to be noted that, in order to ensure that the direct cooling section 210 can enter and exit the ice-making compartment assembly 300, the pressing plate 400 is in the first state before the ice-making compartment assembly 300 is mounted on the box body 100, and the pressing plate 400 is switched to the second state by the control mechanism 500 after the ice-making compartment assembly 300 is mounted on the box body 100. During the after-sales maintenance stage, the pressing plate 400 is in the second state before the ice-making compartment assembly 300 is dismounted, and thus the pressing plate 400 needs to be switched to the first state by the control mechanism 500 before the ice-making compartment assembly 300 is dismounted from the box body 100. After the ice-making compartment assembly 300 is repaired, the ice-making compartment assembly 300 is mounted on the box body 100, and the pressing plate 400 is switched from the first state to the second state by the control mechanism 500.

[0170] In the embodiment, the control mechanism 500 is arranged to control the pressing plate 400 to switch between the first state and the second state, so that the pressing plate 400 can be integrated into the ice-making compartment assembly 300 when the ice-making compartment assembly 300 is modularly assembled. The pressing plate 400 is mounted or dismounted together with the ice-making compartment assembly 300, which facilitates the mounting or dismounting of the pressing plate 400 and the ice-making compartment assembly 300, reduces the difficulty of mounting or dismounting, and simplifies the operation of the workers.

[0171] In the related art, the pressing plate 400 is usually separately sent to the mounting position after the ice cube tray 320 and the direct cooling section 210 are mounted, and then the pressing plate 400 is mounted in place by bolts. However, the existence of the ice cube tray 320, the direct cooling section 210 and the first shell 310 causes a small mounting space, and the workers have a large operation difficulty and a low installation efficiency. The embodiment avoids the situation that it is difficult to connect the pressing plate 400 and the ice cube tray 320 by bolts due to the small mounting space when the ice-making compartment 350 is completely defined by the first shell 310, thereby bringing inconvenience to the installation of the ice-making compartment assembly 300.

[0172] In the embodiment, the control mechanism 500 is arranged to mount the pressing plate 400 in place, instead of mounting the pressing plate 400 in place by bolts, thereby reducing the operation difficulty of the workers and improving the installation efficiency.

[0173] In some embodiments, the control mechanism 500 is arranged close to the opening of the ice-making compartment 350 towards the mouth of the box body. In this way, the workers can easily operate the control mechanism 500.

[0174] In some embodiments, the control mechanism 500 is provided to press the direct cooling section 210 against the ice cube tray 320 by the pressing plate 400, instead of by the bolt, when the ice making chamber 350 is defined by the first housing 310 and other structures.

[0175] In some embodiments, as shown in FIG. 6, FIG. 20-23 and FIG. 25, the control mechanism 500 includes a cam 510, a rotating shaft 540 and a connecting block 520. The connecting block 520 is provided on the ice cube tray 320, and a movable slot 521 is provided on the connecting block 520. The movable slot 521 has a lateral third opening 522. The cam 510 is connected to the rotating shaft 540, and the rotating shaft 540 is movably provided in the movable slot 521. The cam 510 has a first posture and a second posture, and the cam 510 is rotated to switch between the first posture and the second posture.

[0176] When the cam 510 is in the first posture, the rotating shaft 540 can drive the cam 510 to enter the movable slot 521 from the third opening 522, and the pressing plate 400 is in the first state. When the cam 510 is in the second posture, the cam 510 presses against the pressing plate 400, and the pressing plate 400 is switched to the second state.

[0177] The connecting block 520 is fixedly connected to the bottom of the ice cube tray 320, and the cam 510 is rotatably connected to the connecting block 520 by the rotating shaft 540, while the connecting block 520 itself is stationary.

[0178] In this embodiment, the connecting block 520 is provided separately from the ice cube tray 320. In other embodiments, the connecting block 520 can be integrally formed with the ice cube tray 320.

[0179] Before the ice-making chamber assembly 300 is installed, the pressing plate 400 is installed under the ice cube tray 320 by connecting block 520, when the cam 510 is in the first position, the pressing plate 400 is not pressed against the bottom of the ice cube tray 320, the pressing plate 400 is in the state of being placed on the cam 510, so the gap between the pressing plate 400 and the ice cube tray 320 is large and forms the first channel 330 for the direct cooling section 210 to enter. After the direct cooling section 210 enters the first channel 330, the cam 510 is rotated, the cam 510 gradually switches from the first position to the second position, the cam 510 lifts the pressing plate 400 towards the ice cube tray 320, so that the gap between the pressing plate 400 and the ice cube tray 320 is reduced, so that the pressing plate 400 presses the direct cooling section 210 against the ice cube tray 320, thereby completing the installation of the ice-making chamber assembly 300.

[0180] Similarly, when the ice-making chamber assembly 300 is removed, because the cam 510 is in the second position, the cam 510 is first rotated so that the cam 510 gradually switches from the second position to the first position, the pressing plate 400 gradually moves away from the ice cube tray 320, the gap between the pressing plate 400 and the ice cube tray 320 becomes larger, the first channel 330 is formed again, the pressing of the direct cooling section 210 is released, and the ice-making chamber assembly 300 is removed from the tank 100.

[0181] In this embodiment, please refer to FIGS. 24-26, the cam 510 includes a cam body 511, a large circle part 512, a small circle part 513 and a handle 530 arranged on the cam body 511. The handle 530 is arranged on one side of the cam body 511, and the large circle part 512 and the small circle part 513 are arranged at two ends of the cam body 511 respectively. When the cam 510 switches from the first position to the second position, the cam 510 rotates to the small circle part 513 and lifts the pressing plate 400 towards the ice cube tray 320, and the cam 510 continues to rotate until the small circle part 513 presses the pressing plate 400 at the edge close to the handle 530, at this time, the pressing plate 400 prevents the handle 530 from continuing to move, and the cam 510 is in the second position.

[0182] Please refer to FIG. 27-28, the cam 510 is to rely on the small round part 513 to lift the pressing plate 400, but the small round part 513 is not always in contact with the pressing plate 400. When the cam 510 is in the first attitude, the small round part 513 is not facing the pressing plate 400, but is towards the side, at this time the pressing plate 400 is not lifted, but is in contact with the cam body 511, with the rotation of the cam 510, the cam 510 gradually changes from the first attitude to the second attitude, in this process, the small round part 513 gradually changes from not in contact with the pressing plate 400, to the side edge of the small round part 513 in contact with and lifts the pressing plate 400, until the cam 510 is in the second attitude, the pressing plate 400 is also in contact with the other side edge of the small round part 513.

[0183] When the cam 510 is in the second attitude, the small round part 513 will still push the pressing plate 400, ensuring that the pressing plate 400 presses the direct cooling section 210 against the ice tray 320.

[0184] Through such a structure, when the cam 510 is in the second attitude, the position of the pressing plate 400 can be stabilized, ensuring that the direct cooling section 210 is pressed against the ice tray 320. Moreover, the transition process from the first attitude to the second attitude can also be smooth.

[0185] The small round part 513 and the large round part 512 can be provided as arcs, the arc length and the central angle of the large round part 512 and the small round part 513 can be provided as different, and both sides of the small round part 513 can be provided as planes.

[0186] The included angle between the line connecting the centers of the large round part 512 and the small round part 513 and the extension direction of the handle 530 is denoted as ∠a1, the rotation angle of the cam 510 when switching from the first attitude to the second attitude is denoted as ∠a2, and it is satisfied that ∠a1> ∠a2.

[0187] Since when rotating the cam 510, the handle 530 is to be rotated to a position close to the pressing plate 400, and ∠a1> ∠a2 is set, the handle 530 can pass through the highest point of the cam 510 in the process of rotation, that is, the edge of the small round part 513 pushes against the pressing plate 400, so that the handle 530 can be rotated to a position close to the pressing plate 400.

[0188] Please refer to FIG. 20 and FIG. 29, when the cam 510 is in the second position, the highest point of the cam 510 and the handle 530 are respectively located on both sides of the contact position between the cam 510 and the pressing plate 400. In this case, the cam 510 has a tendency to continue rotating in the direction of rotation from the first position to the second position, and the handle 530 also has a tendency to move in this direction of rotation, while the pressing plate 400 blocks the handle 530, which cannot continue to rotate, thereby limiting the continued rotation of the cam 510, so as to achieve a locked state, so that the pressing plate 400 can maintain the state of pressing the direct cooling section 210 against the ice cube tray 320, and at the same time, the cam 510 cannot be converted from the second position to the first position without external intervention.

[0189] In some embodiments, the rotating shaft 540 is in close contact with the connecting block 520, further preventing the rotating shaft 540 from rotating relative to the connecting block 520 without external force. Specifically, the size of the movable groove 521 is slightly smaller than the size of the rotating shaft 540, and the rotating shaft 540 is clamped in the movable groove 521, so that the rotating shaft can rotate in the movable groove 521 under the action of external force.

[0190] The connecting block 520 is also provided with a first limiting portion 5232, which faces the third opening 522 of the movable groove 521; when the cam 510 is in the second position, the end of the first limiting portion 5232 closer to the ice cube tray 320 is closer to the end of the large circular portion 512 away from the ice cube tray 320, so as to prevent the rotating shaft 540 from leaving the movable groove 521 from the third opening 522.

[0191] In this way, the rotating shaft 540 can enter the movable groove 521 from the third opening 522, and after the direct cooling section 210 is arranged in the first channel 330, the cam 510 can be prevented from separating from the movable groove 521 from the third opening 522.

[0192] It is noted that, when the cam 510 is in the first position, the first limiting portion 5232 is closer to one end of the ice bin 320 than the large circular portion 512, in other words, the cam 510 can avoid the first limiting portion 5232, so that the rotating shaft 540 can enter and exit the movable slot 521 from the third opening 522. In addition, it is noted that, when the cam 510 is in the first position, the handle 530, the small circular portion 513 and the cam body 511 can all avoid the first limiting portion 5232 on the path of the cam 510 out of the movable slot 521. As the small circular portion 513 and the cam body 511 are arranged such that, when the cam 510 is in the first position, the end thereof away from the ice bin 320 is closer to the ice bin 320 than the end of the first limiting portion 5232, and the handle 530 is arranged in the area outside the third opening 522. When the cam 510 is in the second position, the first limiting portion 5232 blocks the large circular portion 512 on the path of the cam 510 out of the movable slot 521, so that the cam 510 can only be limited in the movable slot 521, and the rotating shaft 540 cannot exit the movable slot 521.

[0193] Referring to FIGS. 24-26, the radius of the large circular portion 512 is denoted as R1 mm, and the radius of the small circular portion 513 is denoted as R2 mm. The connecting block 520 is further provided with an extension portion 5231, which is located on the side of the connecting block 520 away from the ice bin 320 and extends along the extension direction of the movable slot 521. The extension portion 5231 is arranged to be opposite to the large circular portion 512 when the cam 510 is in the second position. In some embodiments, the extension portion 5231 is arranged to be opposite to and in contact with the large circular portion 512 when the cam 510 is in the second position, thereby supporting the large circular portion 512 to reduce the load of the inner wall of the movable slot 521 on the rotating shaft 540.

[0194] The first limiting portion 5232 is arranged at one end of the extension portion 5231 close to the third opening 522. The first limiting portion 5232 is arc-shaped, and the radius of the first limiting portion 5232 is denoted as R3 mm.

[0195] The limiting portion 5232 is closer to the third opening 522 in the direction facing the direct cooling section 210 than the extension portion 5231, so as to be closer to the cam 510 at the third opening 522, and thus can resist the large circular portion 512 at this position.

[0196] A length of the cam body 511 in a vertical direction of a line connecting the centers of the large circle part 512 and the small circle part 513 is L1 mm; a plane formed by the axis of the rotating shaft 540 at different positions during movement of the rotating shaft 540 toward the third opening 522 is a reference plane 550, the reference plane 550 is parallel to an extending direction of the movable groove 521, a distance between the reference plane 550 and an end of the first limiting part 5232 is L2 mm, and a distance between the reference plane 550 and the extending part 5231 is L4 mm; and the following conditions are satisfied: L4>R1, R3>R1, R1>L1, L2>L1 / 2, and R1>L2.

[0197] In this way, the distance of movement of the cam 510 toward the third opening 522 can be limited, the cam 510 can be prevented from moving in the movable groove 521 and being released at the third opening 522, and the direct-cooling section 210 can be stably pressed against the ice bin 320 by the pressing plate 400.

[0198] In some embodiments, referring to FIGS. 5, 21-23, the ice bin 320 is provided with a receiving groove 321 for receiving the direct-cooling section 210, and the pressing plate 400 is further provided with a supporting plate 410 for pressing the direct-cooling section 210; when the pressing plate 400 is in the second state, the supporting plate 410 presses the direct-cooling section 210 in the receiving groove 321.

[0199] The direct-cooling section 210 is in a U shape, and the receiving groove 321 provided at the bottom of the ice bin 320 is also in a U shape and matches the shape of the direct-cooling section 210. When the direct-cooling section 210 is inserted into the ice-making chamber 350, the direct-cooling section 210 can be pressed into the receiving groove 321 by the pressing plate 400 and directly contact the ice bin 320.

[0200] The supporting plate 410 can be provided in multiple numbers and distributed at different positions of the direct-cooling section 210. Providing multiple supporting plates 410 can make the force of the pressing plate 400 on the direct-cooling section 210 more uniform, and ensure that the part of the direct-cooling section 210 corresponding to the receiving groove 321 can enter the receiving groove 321.

[0201] In some embodiments, the supporting plate 410 includes a connecting part 411 and an abutting part 412, the connecting part 411 is connected to the pressing plate 400, and the abutting part 412 is connected to the connecting part 411 and used for pressing the direct-cooling section 210.

[0202] The connecting portion 411 is used to mount the supporting plate 410 on the pressing plate 400, so that the supporting plate 410 can move with the movement of the pressing plate 400. When the pressing plate 400 presses the direct cooling section 210, the abutting portion 412 abuts against the direct cooling section 210. In some embodiments, the abutting portion 412 is formed with a groove matching the shape of the direct cooling section 210, so that the abutting portion 412 can more smoothly abut against the direct cooling section 210. For example, the direct cooling section 210 is tubular, and the groove formed on the abutting portion 412 is an arc-shaped groove.

[0203] In some embodiments, the abutting portion 412 is connected to one end of the connecting portion 411 and extends to one side of the connecting portion 411. The abutting portion 412 is elastic and can be deformed to a certain extent, so that the abutting portion 412 can apply a proper pressing force to the direct cooling section 210 when the direct cooling section 210 is pressed against the ice cube tray 320, and the direct cooling section 210 is protected to a certain extent.

[0204] In some embodiments, the pressing plate 400 is further provided with a supporting plate 413 on the side facing the ice cube tray 320, and the one end of the supporting plate 413 away from the pressing plate 400 is located on the side of the connecting portion 411 facing the pressing plate 400.

[0205] The supporting plate 413 can limit the position of the connecting portion 411, and can prevent the abutting portion 412 from being deformed too much.

[0206] In some embodiments, each supporting plate 410 can be provided with two spaced-apart supporting plates 413, and the two supporting plates 413 are arranged at two opposite edges of the corresponding connecting portion 411.

[0207] In some embodiments, the pressing plate 400 is provided with a first through hole 414, the connecting block 520 is fixed to the first through hole 414, and the third opening 522 is located on the side of the pressing plate 400 away from the direct cooling section 210. In this way, the handle 530 and the cam 510 can be mounted on the side of the pressing plate 400 away from the direct cooling section 210.

[0208] In some embodiments, the pressing plate 400 is connected with the ice bin 320 through the connecting block 520. Since the connecting block 520 is connected with both the pressing plate 400 and the ice bin 320, and the pressing plate 400 needs to press against the direct cooling section 210, the cam 510 is arranged on the side of the pressing plate 400 away from the ice bin 320, and the handle 530 is also arranged on the side of the pressing plate 400 away from the ice bin 320. In order to connect the cam 510 and the handle 530, the first through hole 414 is arranged on the pressing plate 400, and the connecting block 520 is fixed in the first through hole 414, so that a part of the connecting block 520 is located on the side of the pressing plate 400 away from the ice bin 320, thereby achieving the installation of the cam 510 and the handle 530.

[0209] In some embodiments, as shown in FIG. 29, the pressing plate 400 is further provided with a recess 415 on the side away from the ice bin 320, and the first through hole 414 is in communication with the recess 415. When the cam 510 is in the second position, the handle 530 is completely arranged in the recess 415.

[0210] The recess 415 is arranged on the pressing plate 400, so that the handle 530 can be hidden in the state that the ice-making compartment assembly 300 is installed. In this way, the space of the ice-making compartment 350 is reduced, and the installation of other components of the ice-making compartment assembly 300 is facilitated.

[0211] In some embodiments, as shown in FIGS. 30-32, the refrigerator further comprises a mounting plate 600 and a heat preservation clamp 700.

[0212] The mounting plate 600 is mounted on the outer wall of the cabinet 100, and the mounting plate 600 is provided with a surrounding plate 620 forming a second passage 610. The surrounding plate 620 is inserted into the first opening 110, and the second passage 610 is used for the direct cooling section 210 to pass through, so that the direct cooling section 210 passes through the mounting plate 600 and enters the inside of the cabinet 100.

[0213] In the present embodiment, the surrounding plate 310 is in the form of a sleeve. The direct cooling section 210 passes through the center of the second passage 610, that is, at least a part of the direct cooling section 210 extends into the cabinet 100 from the center of the surrounding plate 620.

[0214] The heat preservation clamp 700 comprises a first clamp 710 and a second clamp 720, which are arranged in the second channel 610 and cover each other, and the surrounding plate 620 limits the positions of the first clamp 710 and the second clamp 720. The first clamp 710 and the second clamp 720 jointly clamp and wrap a part of the direct cooling section 210 to limit the position change of the direct cooling section 210 at the first opening 110.

[0215] In the embodiment, the first clamp 710 and the second clamp 720 are both foam clamps, which are arranged in an up-down manner. The first clamp 710, the second clamp 720 and the surrounding plate 620 limit the position change of the direct cooling section 210 at the first opening 110.

[0216] The arrangement of the heat preservation clamp 700 can reduce the heat exchange between the direct cooling section 210 and the environment outside the ice-making chamber assembly 300, and reduce the influence of the direct cooling section 210 on the cooling capacity of the ice-making chamber assembly 300.

[0217] In the related art, the direct cooling section 210 is arranged on the box body 100 in advance, and a part of the direct cooling section 210 is used to cool the ice-making machine assembly. There are two installation modes of the direct cooling section 210. One is to install each component of the ice-making machine assembly in the box body 100 one by one, and the other is to integrate at least one component of the ice-making machine assembly to form an integrated structure, that is, to modularly install the ice-making machine assembly, and to directly install the integrated structure in the box body 100. Both of the two installation modes need to be installed in cooperation with the part of the direct cooling section 210 used to cool the ice-making machine assembly, so it is necessary to reduce the shaking of the direct cooling section 210.

[0218] The refrigerator of the embodiment, since the part of the direct cooling section 210 used to cool the ice-making chamber assembly 300 is not integrated with the ice-making chamber assembly 300 as a whole structure, and the direct cooling section 210 is arranged in the box body 100 in advance, when the ice-making chamber assembly 300 is installed, it is necessary to keep the direct cooling section 210 from shaking, that is, to limit the position of the direct cooling section 210, so as to ensure the smooth installation of the ice-making chamber assembly 300.

[0219] The arrangement of the mounting plate 600 and the heat preservation clamp 700 can simultaneously limit the position of the direct cooling section 210, thereby limiting the position change of the direct cooling section 210 at the first opening 110, and keeping the direct cooling section 210 from shaking, so as to ensure the smooth installation of the ice-making chamber assembly 300.

[0220] In the installation, the first clamp 710 and the second clamp 720 can be clamped on the direct cooling section 210 first, and then the first clamp 710, the second clamp 720 and the direct cooling section 210 are inserted into the second channel 610 to form an integral whole, and then the integral whole is inserted into the first opening 110 from the outside of the tank 100 until the mounting plate 600 is abutted and mounted on the outer wall of the tank 100.

[0221] In the inline tube technology, for the ice-making chamber assembly 300 without the direct cooling section 210, each part of the ice-making chamber assembly 300 including the thermal insulation clamp 700 needs to be installed one by one, and for the ice-making chamber assembly 300 with the direct cooling section 210, the direct cooling section 210 is integrated on the ice-making chamber assembly 300 when the direct cooling section 210 is integrated on the ice-making chamber assembly 300, and in the embodiment, since the direct cooling section 210 is inserted into the ice-making chamber assembly 300, the installation of the thermal insulation clamp 700 is inconvenient.

[0222] In the embodiment, the thermal insulation clamp 700 and the direct cooling section 210 are pre-installed on the mounting plate 600, and the mounting plate 600 can conveniently install the thermal insulation clamp 700 and the direct cooling section 210 on the tank 100.

[0223] Referring to FIGS. 31 and 32, in some embodiments, the direct cooling section 210 has a positioning portion 211 located between the first clamp 710 and the second clamp 720, and the positioning portion 211 is clamped and wrapped by the first clamp 710 and the second clamp 720.

[0224] The positioning portion 211 can determine the position of the first clamp 710 and the second clamp 720 during installation.

[0225] In some embodiments, the positioning portion 211 is a curved pipe on the direct cooling section 210. In other embodiments, other shapes can be provided to distinguish from the part of the direct cooling section 210 other than the positioning portion 211.

[0226] Referring to FIGS. 40 and 42, in some embodiments, the first clamp 710 includes a first limiting boss 711, and the second clamp 720 is provided with a first matching groove 721, and the first limiting boss 711 is inserted into the first matching groove 721 to limit the relative position of the first clamp 710 and the second clamp 720.

[0227] When the first limiting protrusion 711 is inserted into the first matching groove 721, the relative position of the first clamp 710 and the second clamp 720 is limited, that is, the first clamp 710 and the second clamp 720 cannot be displaced even during the process of being inserted into the second channel 610.

[0228] In the embodiment, two first limiting protrusions 711 are arranged at the two ends of the first clamp 710 along the extension direction of the second channel 610, and two first matching grooves 721 are arranged at the two ends of the first clamp 710, and two second matching grooves 722 are arranged at the two ends of the second clamp 720.

[0229] In the embodiment, the two first limiting protrusions 711 also extend to the edges of the two ends of the first clamp 710, and the second matching grooves 722 also extend to the edges of the two ends of the second clamp 720.

[0230] In some embodiments, the first clamp 710 further comprises a second limiting protrusion 712, the second clamp 720 further comprises a second matching groove 722, the second limiting protrusion 712 is inserted into the second matching groove 722, and the second limiting protrusion 712 corresponds to the positioning part 211 to limit the relative position of the positioning part 211 and the heat preservation clamp 700, and the positioning part 211 is clamped between the first clamp 710 and the second clamp 720.

[0231] When the second limiting protrusion 712 is inserted into the second matching groove 722, the position of the direct cooling section 210 relative to the first clamp 710 and the second clamp 720 can be limited, and displacement of the direct cooling section 210 relative to the first clamp 710 or the second clamp 720 can be prevented.

[0232] In the embodiment, the positioning part 211 is a bent pipe, the second limiting protrusion 712 is arranged at the bent pipe, and the bent pipe surrounds a part of the outer circumferential surface of the second limiting protrusion 712 to form a state in which the bent pipe is hooked on the second limiting protrusion 712, thereby limiting the relative position of the positioning part 211 and the heat preservation clamp 700.

[0233] In some embodiments, referring to FIGS. 38-40, the surrounding plate 620 is provided with a third through hole 621, the edge of the third through hole 621 is provided with a cantilever 622, the side surface of the first clamp 710 or the second clamp 720 is provided with a groove 730 at a position corresponding to the cantilever 622, and the edge of the third through hole 621 is further provided with a buckle part 623, the cantilever 622 cooperates with the buckle part 623 to enable the cantilever 622 to be pressed in the groove 730.

[0234] In some embodiments, the cantilever 622 is arranged opposite and partially overlapping the buckle portion 623. When the cantilever 622 is subjected to a force in the direction of the heat preservation clamp 700, the end of the cantilever 622 is pressed from the side of the cantilever 622 away from the heat preservation clamp 700 to the side of the buckle portion 623 close to the heat preservation clamp 700, so that the cantilever 622 is pressed in the groove 730.

[0235] The cantilever 622 is movable at the third through hole 621. When the heat preservation clamp 700 is arranged in the second passage 610, the cantilever 622 is arranged in the groove 730 and is pressed against the first clamp 710 or the second clamp 720, so as to increase the relative force between the first clamp 710 and the second clamp 720 and fix the first clamp 710 and the second clamp 720.

[0236] In some embodiments, referring to FIGS. 41 and 42, the baffle 620 is provided with a third through hole 621, and the edge of the through hole is provided with a cantilever 622. The heat preservation clamp 700 further comprises a fixing pin 740, which penetrates the first clamp 710, the second clamp 720 and the cantilever 622 and abuts against the side of the cantilever 622 away from the heat preservation clamp 700, so that the cantilever 622 abuts against the first clamp 710 or the second clamp 720.

[0237] The cantilever 622 is movable at the third through hole 621. After the fixing pin 740 is arranged, the fixing pin 740 can press the cantilever 622, so that the cantilever 622 can be pressed against the first clamp 710 or the second clamp 720, thereby fixing the first clamp 710 and the second clamp 720.

[0238] Specifically, the cantilever 622 is provided with a fourth through hole 624, one end of the fixing pin 740 penetrates the fourth through hole 624 and abuts against the first clamp 710 or the second clamp 720, and the other end of the fixing pin 740 abuts against the side of the cantilever 622 away from the heat preservation clamp 700.

[0239] In some embodiments, the fixing pin 740 is in close contact with the fourth through hole 624, so as to prevent the fixing pin 740 from being separated from the fourth through hole 624 without external force, thereby pressing the cantilever 622.

[0240] In some embodiments, the fixing pin 740 is further provided with a protrusion 742 on the side wall thereof, and the cantilever 622 is further provided with a limiting opening 625 communicating with the fourth through hole 624, and the protrusion 742 is located in the limiting opening 625. The heat preservation clamp 700 is further provided with a screw on the side away from the cantilever 622, and the screw is screwed with the fixing pin 740 to fix the fixing pin 740 and press the cantilever 622. Since the protrusion 742 is located in the limiting opening 625, the fixing pin 740 is prevented from rotating when the screw is tightened, and the limiting effect is achieved, which facilitates the operation of the staff.

[0241] In some embodiments, referring to FIG. 33, the mounting plate 600 comprises a first fixing plate 630 and a second fixing plate 640 arranged in an up-down manner, and referring to FIGS. 34-37, the first fixing plate 630 is provided with a first notch 631 extending to the edge thereof at one end, and the second fixing plate 640 is provided with a second notch 641 extending to the edge thereof at one end, the first notch 631 and the second notch 641 jointly form a fixing hole 650 for the straight cooling section 210 to pass through, the surrounding plate 620 is arranged around the fixing hole 650, and the first notch 631 and the second notch 641 jointly hold the straight cooling section 210 to limit the change of the position of the straight cooling section 210 at the first opening 110.

[0246] The first fixing plate 630 is provided with a second limiting part 632, which is arranged at a part of the edge of the first fixing plate 630, and is hung on the outer wall of the box body 100.

[0247] The ice making compartment assembly 300 is arranged at a corner on the top of the box body 100, and correspondingly, the first opening 110 is also located near a corner on the top of the box body 100.

[0248] The second limiting part 632 is arranged on the top edge and the side edge of the first fixing plate 630, and forms a plate-shaped bending shape. By arranging the second limiting part 632, the first fixing plate 630 can be hung on the top wall of the box body 100, and the cooperation of the second limiting part 632 and the side wall of the box body 100 positions the first fixing plate 630, so that the first fixing plate 630 is hung on the outer wall of the box body 100, and the position of the direct cooling section 210 is more stable. After the refrigerator foaming process, the foam layer can abut the first fixing plate 630 and the second fixing plate 640 on the outer wall of the box body 100, achieving fixation.

[0249] Referring to FIGS. 34 and 36, in some embodiments, the first fixing plate 630 is provided with a first protruding part 633 arranged on a part of the edge of the fixing hole 650, and the second fixing plate 640 is provided with a second protruding part 642 arranged on a part of the edge of the fixing hole 650, and the first protruding part 633 and the second protruding part 642 jointly clamp the direct cooling section 210.
