[0186] Please refer to Figures 1-4 A refrigerator according to a preferred embodiment of the present invention includes: a cabinet, a refrigeration circulation pipeline 200, and an ice-making chamber assembly 300.

[0187] The box body includes an outer shell and a box liner 100 disposed inside the outer shell. The box liner 100 has a first opening 110 in its inner wall and a liner opening for installing a box door.

[0188] An installation space is formed between the outer shell and the inner liner 100 for installing other refrigerator components and forming a foamed insulation layer. The interior of the inner liner 100 forms a refrigeration chamber, which is a refrigerator compartment, a variable temperature compartment, or a freezer compartment.

[0189] The first opening 110 is a hole made in the wall of the box liner 100. The first opening 110 is connected to the foam insulation layer. In other words, the first opening 110 is not used to set the box door.

[0190] The cabinet door is located at the inlet of the cabinet liner 100. By controlling the opening and closing of the cabinet door, the opening and closing of the refrigeration chamber can be controlled.

[0191] The refrigeration circulation pipe 200 is arranged between the outer shell and the inner box 100, and at least a portion of the refrigeration circulation pipe 200 extends into the inner box 100 from the first opening 110 and is referred to as the direct cooling section 210.

[0192] The refrigerator has a refrigeration cycle system for cooling the refrigerator liner 100. This refrigeration cycle system generally includes components such as a compressor, condenser, dryer filter, capillary tube, and evaporator, all connected via refrigeration cycle piping 200. The operation of the refrigeration cycle system includes compression, condensation, throttling, and evaporation processes. Specifically, the compression process is as follows: after the refrigerator power cord is plugged in, with the thermostat contacts closed, the compressor starts working. Low-temperature, low-pressure refrigerant from the evaporator is drawn into the compressor and compressed into high-temperature, high-pressure superheated gas within the compressor cylinder before being discharged into the condenser. The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, its temperature continuously decreasing until it is gradually cooled into room-temperature, high-pressure saturated vapor, and further cooled into a saturated liquid. The temperature then no longer decreases, and the pressure of the refrigerant remains almost constant throughout the condensation process. The throttling process is as follows: After condensation, the saturated liquid refrigerant flows into the capillary tube after being filtered to remove moisture and impurities through the dryer filter. The capillary tube then throttles and reduces pressure, transforming the refrigerant into a low-pressure, room-temperature wet vapor. The evaporation process is as follows: The low-pressure, room-temperature wet vapor enters the evaporator, absorbs heat, and vaporizes, lowering the temperature of the evaporator and its surroundings, thus cooling the refrigeration chamber and transforming the refrigerant into a low-temperature, low-pressure gas. The refrigerant exiting the evaporator returns to the compressor, repeating the above process. Energy is converted through the state change of the refrigerant, transferring heat from inside the refrigerator to the outside air, thereby achieving the refrigerator's refrigeration cycle. When the evaporator is located on the wall of the refrigeration chamber, it is a direct-cooling refrigerator; when the evaporator is located within the refrigerator's air duct, it is a frost-free refrigerator. The above-described structural configuration and operating principle of the refrigerator's refrigeration cycle system are existing technologies and will not be elaborated upon further in this application.

[0193] The direct cooling section 210 is part of the refrigeration circulation pipeline 200. For ease of description, the part that extends into the interior of the cabinet 100 is referred to as the direct cooling section 210.

[0194] Since the refrigerator of this embodiment has already provided a first opening 110 on the wall of the liner 100 for the refrigeration circulation pipe 200 to pass through, the refrigeration circulation pipe 200 extends into the interior of the refrigerator body through the first opening 110. In the case where the first opening 110 is not provided on the wall of the liner 100, the pipe can also extend into the interior of the liner 100 from the opening corresponding to the refrigerator door.

[0195] The ice-making chamber assembly 300 includes a first housing 310 and an ice-making unit 360. The first housing 310 defines an ice-making chamber 350. The ice-making unit 360 is disposed in the ice-making chamber 350 and includes an ice tray 320. The first housing 310 is detachably installed inside the liner 100. The outer surface of the first housing 310 is provided with a second opening 311 communicating with the ice-making chamber 350. The direct cooling section 210 passes through the second opening 311 and at least a portion of it contacts the ice tray 320.

[0196] The ice-making unit 360 is used to produce ice blocks, and the first housing 310 is used to define the ice-making chamber 350. The first housing 310 may define the ice-making chamber 350 entirely by itself, or it may define the ice-making chamber 350 together with other structures. The ice-making chamber 350 is separated from the refrigeration chamber.

[0197] Generally speaking, since the direct cooling section 210 can cool the ice-making chamber 350, the ice-making chamber assembly 300 can be installed in the refrigerator compartment or the freezer compartment.

[0198] The ice-making unit 360 includes an ice tray 320 and a water pipe supplying water to the ice tray 320. The direct cooling section 210 exchanges heat for the ice tray 320. After the water in the ice tray 320 freezes, a driving device drives the ice tray 320 to flip, so that the opening of the ice tray 320 faces downwards, for ice removal. An ice storage box is usually installed below the ice tray 320 to store the ice that has fallen out of the ice tray 320. The refrigeration pipe exchanges heat with the air in the ice-making chamber 350, which also ensures a low temperature in the ice storage box. Afterwards, the ice tray 320 is reset, and the water pipe adds water to the ice tray 320 to repeat the ice-making process.

[0199] In this embodiment, the ice-making chamber assembly 300 itself does not have a refrigeration pipe; the direct cooling section 210 of the refrigerator's refrigeration circulation pipe 200 provides cooling to the ice-making chamber assembly 300. The refrigeration circulation pipe 200 is used to simultaneously cool the refrigerator liner 100 and the ice-making chamber 350.

[0200] The second opening 311 is designed to facilitate the entry and exit of the direct cooling section 210 into and out of the first housing 310, i.e., into and out of the ice-making chamber 350, when the ice-making chamber assembly 300 is disassembled and assembled. After the ice-making chamber assembly 300 is installed, the direct cooling section 210 directly contacts the ice tray 320, and the direct cooling section 210 directly exchanges heat with the ice tray 320 to ensure the cooling effect of the ice tray 320 and guarantee ice-making efficiency.

[0201] When installing the ice-making chamber assembly 300, 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 inside the liner 100, and at least a portion of the direct cooling section 210 is able to contact the ice tray 320; when disassembling the ice-making chamber assembly 300, the first housing 310 moves outward from the liner 100 until the direct cooling section 210 is completely pulled out from the second opening 311.

[0202] In other words, when installing the ice chamber assembly 300, the first housing 310 will be connected to the inner wall of the liner 100 only after the direct cooling section 210 enters the ice chamber 350; similarly, when disassembling the ice maker assembly, the connection between the first housing 310 and the liner 100 will be disconnected first, and then the direct cooling section 210 will be pulled out from the second opening 311.

[0203] With this structure, the ice-making chamber assembly 300 is installed as if inserted into the direct cooling section 210. Therefore, during the refrigerator manufacturing process, the refrigeration circulation pipe 200 can be pre-embedded in the inner cabinet 100, and a portion of the refrigeration circulation pipe 200 extends into the inner cabinet 100 to form the direct cooling section 210. The ice-making chamber assembly 300 is then assembled as a whole, the second opening 311 is aligned with the direct cooling section 210, the direct cooling section 210 is inserted into the interior of the ice maker, and the first housing 310 and the inner cabinet 100 are connected, thus achieving modular installation of the ice maker.

[0204] When the ice-making chamber assembly 300 needs maintenance after service, first disconnect the first housing 310 from the inner chamber 100. Move the first housing 310 outward from the inner chamber 100 until the direct cooling section 210 is completely pulled out from the second opening 311. The ice-making chamber assembly 300 remains an integrated structure, thus enabling modular disassembly of the ice-making chamber assembly 300.

[0205] After the ice-making chamber assembly 300 is repaired, it can still be installed onto the refrigerator liner 100 according to the installation method used in the refrigerator manufacturing process.

[0206] Therefore, the ice chamber assembly 300 can be modularly disassembled and assembled during both the refrigerator manufacturing process and after-sales maintenance process, eliminating the need to disassemble and assemble each part of the ice chamber assembly 300 individually, reducing the difficulty of assembly and disassembly, and simplifying the operation for staff.

[0207] In the existing technology, there are usually two types of ice chamber components 300 and two corresponding installation methods.

[0208] One type of ice-making chamber assembly 300 does not have its own refrigeration pipes. During refrigerator manufacturing, the refrigeration circulation pipe 200 pre-embedded in the liner 100 is a complete circuit, similar to the refrigeration circulation pipe 200 in this embodiment, with a portion extending into the liner 100 to form a direct cooling section 210. For this type of ice-making chamber assembly 300, both during refrigerator manufacturing and after-sales maintenance, disassembly and assembly of the ice-making chamber assembly 300 requires the individual disassembly and assembly of each component, making the assembly and disassembly cumbersome.

[0209] Another type of ice-making chamber assembly 300 has its own refrigeration pipe. During the refrigerator manufacturing process, the refrigeration circulation pipe 200 pre-embedded on the inner liner 100 is disconnected, with the disconnected end extending into the inner liner 100. After the outer shell of the ice-making chamber assembly 300 is connected to the inner liner 100, the refrigeration pipe and the disconnected end of the refrigeration circulation pipe 200 are welded together, so that the refrigeration pipe and the refrigeration circulation pipe 200 are connected. In this situation, when the ice-making chamber assembly 300 needs maintenance during the after-sales phase, it is impossible to separate the refrigeration pipe and the refrigeration circulation pipe 200 without damaging the components. In this case, to remove the ice-making chamber assembly 300, each part of the ice-making chamber assembly 300 must be removed one by one, and when reinstalling the ice-making chamber assembly 300, each part must also be reinstalled one by one. Therefore, although this ice-making chamber assembly 300 can be modularly installed during the refrigerator manufacturing stage, the problem of cumbersome installation and removal of the ice-making chamber assembly 300 still exists during the after-sales phase.

[0210] The refrigerator described in this embodiment can be modularly disassembled and assembled during both the manufacturing and after-sales maintenance stages. It does not require disassembling and assembling each part of the ice-making chamber assembly 300 individually, nor does it require welding some of the refrigeration pipes of the ice-making chamber assembly 300 to the refrigeration circulation pipeline 200 as in the prior art. This reduces manufacturing processes, lowers the difficulty of assembly and disassembly, and simplifies the operation for staff.

[0211] In some embodiments, please refer to Figures 5-6 The ice-making chamber assembly 300 further includes a pressure plate 400, which is disposed inside the ice-making chamber 350 and connected to the ice-making unit 360. The pressure plate 400 is disposed on the side of the direct cooling section 210 away from the ice tray 320, and the pressure plate 400 is used to press the direct cooling section 210 against the ice tray 320.

[0212] The pressure plate 400 allows the direct cooling section 210 to press against the ice tray 320, thereby ensuring that the direct cooling section 210 can continuously be in direct contact with the ice tray 320.

[0213] The direct cooling section 210 is typically located at the bottom of the ice tray 320, and the pressure plate 400 is located below the direct cooling section 210.

[0214] In this embodiment, the ice-making chamber 350 may be entirely defined by the first housing 310, or it may be defined by the first housing 310 and other structures. These two situations will affect the connection method of the pressure plate 400.

[0215] When the ice-making chamber 350 is defined by the first housing 310 and other structures, the first housing 310 is in an open state.

[0216] In this case, please refer to Figures 7-9 The pressure plate 400 is provided with a first connecting hole 420 that penetrates the pressure plate 400, and the ice tray 320 is provided with a second connecting hole 322 corresponding to the first connecting hole 420; the ice making chamber assembly 300 also includes a connector 323, through which the first connecting hole 420 is connected to the second connecting hole 322.

[0217] In this embodiment, the connector 323 is a bolt, and the first connecting hole 420 and the second connecting hole 322 are bolt holes. The first connecting hole 420 and the second connecting hole 322 are connected by the bolt, thus forming a bolted connection between the pressure plate 400 and the ice tray 320. After the bolt connection is completed, the pressure plate 400 presses the direct cooling section 210 against the ice tray 320.

[0218] Since the first housing 310 is open in this situation, there is enough space for workers to hold the pressure plate 400 and use tools to tighten the bolts onto it.

[0219] In this case, please refer to Figures 10-13 The ice-making chamber assembly 300 further includes a second housing 340. The first housing 310 and the second housing 340 are detachably connected. The first housing 310 and the second housing 340 together define the ice-making chamber 350. The first housing 310 is detachably connected to the inner wall of the box liner 100. The ice-making unit 360 is disposed on the first housing 310.

[0220] Both the first housing 310 and the second housing 340 are part of the entire housing of the ice-making chamber 350. However, when installing the ice-making chamber assembly 300, the ice-making unit 360 is first installed on the first housing 310, then the first housing 310 is installed on the inner wall of the box liner 100, the bolts of the pressure plate 400 are tightened, and then the second housing 340 is installed on the first housing 310 to complete the installation of the entire outer shell of the ice-making chamber assembly 300.

[0221] When disassembling the ice-making chamber assembly 300, the second housing 340 must first be removed from the first housing 310, then the bolts of the pressure plate 400 must be loosened to allow the first channel 330 to reform, and then the first housing 310 and the ice-making unit 360 must be removed from the liner 100 together.

[0222] The first housing 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 housing 340 together define the ice-making chamber 350. The back plate 314 is detachably connected to the inner wall of the box liner 100.

[0223] The semi-shell body 313 mainly provides the top of the ice-making chamber 350 and a side wall near the inner wall of the box liner 100. The back plate 314 provides the rear wall of the ice-making chamber 350. The back plate 314 is connected to the box liner 100, and the semi-shell body 313 is also connected to the box liner 100.

[0224] The first housing 310 is composed of two parts: the half-shell body 313 and the back plate 314. Since the ice-making chamber assembly 300 in this embodiment is located at one corner of the top of the inner box 100, the back plate of the ice-making chamber assembly 300, that is, the back plate 314, is set to correspond to the back plate 314 of the inner box 100. The side wall of the ice-making chamber assembly 300, that is, one side wall on the half-shell body 313, is set to correspond to the side wall of the inner box 100.

[0225] The semi-shell body 313 is a side wall and a top wall of the ice-making chamber assembly 300. The semi-shell body 313 is connected to the back plate 314, forming an open state for the first shell 310. The second shell 340 is a side wall and a bottom wall of the ice-making chamber assembly 300. The semi-shell body 313, the back plate 314, and the second shell 340 form the outer wall of the ice-making chamber assembly 300.

[0226] In some embodiments, please refer to Figures 14-15The refrigerator also includes a fixing plate 120 disposed between the inner liner 100 and the outer shell, and the fixing plate 120 has a first slot 121 opening toward the inner liner 100.

[0227] The box liner 100 is provided with a second through hole corresponding to the first slot 121, and the first housing 310 is provided with a first buckle 312, which passes through the second through hole and engages with the first slot 121.

[0228] Before the first housing 310 is installed, the fixing plate 120 is placed between the inner box 100 and the outer shell. The fixing plate 120 can be screwed to the outer wall of the inner box 100. The fixing plate 120 is equivalent to being embedded in the foam layer between the inner box 100 and the outer shell.

[0229] The first buckle 312 is disposed on the half-shell body 313, and the first buckle 312 engages with the first slot 121 to install the half-shell body 313 on the inner wall of the box liner 100. The back plate 314 is also installed on the inner wall of the box liner 100. Since the ice-making unit 360 is disposed on the first housing 310, the first housing 310 needs to have a certain load-bearing capacity. By setting connection positions on the half-shell body 313 and the back plate 314 respectively, the ice-making chamber assembly 300 is stably installed.

[0230] In some embodiments, the liner 100 further includes a junction box disposed on the side or rear wall of the liner 100; a fourth opening 317 is provided on the first housing 310, through which the junction box enters the ice-making chamber 350, and the top wall of the junction box abuts against at least a portion of the edge of the fourth opening 317 to support the first housing 310. The junction box is also pre-installed on the liner 100 before the ice-making chamber assembly 300 is installed. By providing the fourth opening 317, at least a portion of the junction box extends into the ice-making chamber 350 and serves to support the first housing 310.

[0231] In this embodiment, the junction box is disposed on the side wall of the box liner 100, and the fourth opening 317 is disposed on the half-shell body 313.

[0232] By positioning the junction box in this way, the junction box, the fixing plate 120, and the back plate 314 can jointly support the first housing 310, thereby allowing the first housing 310 to be installed more stably on the box liner 100.

[0233] In some embodiments, please refer toFigure 16 The inner box 100 is provided with a support portion 130, which is disposed on the side wall or rear wall of the inner box 100; the first housing 310 is provided with a fifth opening 318, and the support portion 130 passes through the fifth opening 318 and enters the ice-making chamber 350. The top wall of the support portion 130 abuts against at least a portion of the edge of the fifth opening 318 so that the support portion 130 supports the first housing 310.

[0234] In this embodiment, the support portion 130 is a protrusion protruding from the inner wall of the box liner 100, and the support portion 130 supports the first housing 310 by inserting into the fifth opening 318. In this embodiment, the fifth opening 318 is disposed on the back plate 314.

[0235] Therefore, the support part 130, the junction box, and the fixing plate 120 can all support the first housing 310 and share the weight of the ice chamber assembly 300, so as to ensure that the first housing 310 is more stably installed on the box liner 100, thereby allowing the ice chamber assembly 300 to be stably installed on the box liner 100.

[0236] Please refer to Figures 17-19 The first housing 310 has a first track groove 315 with a lateral opening on its edge, and the second housing 340 has a first slide rail 341 that is slidably connected to the first track groove 315 on its edge. The bottom of the first slide rail 341 abuts against the groove wall of the first track groove 315 so that the first track groove 315 supports the first slide rail 341.

[0237] When installing the second housing 340 onto the first housing 310, align the first slide rail 341 with the first track groove 315, and then slide the second housing 340 toward the back plate 314 so that the second housing 340 is installed on the first housing 310.

[0238] Because the bottom of the first slide rail 341 rests against the wall of the first track groove 315, the structure of the first slide rail 341 and the first track groove 315 can support the second housing 340 and maintain the installation state of the second housing 340 and the first housing 310. In this embodiment, no structure such as the ice-making unit 360 is installed on the second housing 340, so the load-bearing requirements are not high. Therefore, the second housing 340 is not directly connected to the inner box 100, which also allows the overall stability of the ice-making chamber assembly 300.

[0239] The edge of the second housing 340 is also provided with a second track groove 342, and the edge of the first housing 310 is provided with a second slide rail 316 that is slidably connected to the second track groove 342. The extension directions of the first slide rail 341 and the second slide rail 316 are parallel to each other and point towards the bladder opening.

[0240] The second track groove 342 and the second slide rail 316 can also assist the second housing 340 in being installed on the first housing 310, facilitating the connection between the first housing 310 and the second housing 340.

[0241] In this embodiment, the second shell 340 includes an inner shell wall 343 and an outer shell wall 344. The inner shell wall 343 and the outer shell wall form a hollow structure of the second shell 340. An anti-overflow portion is provided at at least a portion of the connection between the inner shell wall 343 and the outer shell wall 344.

[0242] The hollow structure formed by the inner shell wall 343 and the outer shell wall 344 is used to house the foaming layer. Since there may be a temperature difference between the ice-making chamber 350 and the refrigeration chamber inside the liner 100, in order to ensure the temperature stability inside the ice-making chamber 350, it is necessary to block heat exchange between the inside and outside of the ice-making chamber 350 as much as possible.

[0243] In this embodiment, the ice-making chamber assembly 300 is located at one corner of the liner 100. Therefore, only the second housing 340, which is in contact with the air inside the ice-making chamber 350 and the refrigeration chamber, needs to be provided with a foaming layer. The first housing 310, which is in direct contact with the liner 100, does not need to be provided with a foaming layer.

[0244] The overflow prevention feature ensures that the foaming liquid will not leak out of the second housing 340.

[0245] In this embodiment, the first track groove 315, the first slide rail 341, the second track groove 342, and the second slide rail 316 together form at least a portion of the overflow prevention part.

[0246] The first track groove 315 and the second track groove 342 are adjacent to each other. 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-like structure, thereby preventing the foaming liquid from overflowing. In other words, 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 serve as part of the overflow prevention section to prevent the foaming liquid from overflowing.

[0247] When the ice-making chamber 350 is completely defined by the first housing 310, which has at least a top surface, side surface, bottom surface, and back surface, it is difficult to connect the pressure plate 400 using bolts or similar methods. This is because the pressure plate 400 is located inside the ice-making chamber 350, making it difficult for workers to reach their hands and tools inside. To solve this problem, please refer to... Figure 20 The refrigerator also includes a control mechanism 500, which is disposed inside the ice-making chamber 350. The control mechanism 500 is connected to the pressure plate 400 and drives the pressure plate 400 to switch between a first state and a second state. When the pressure plate 400 is in the first state, a first channel 330 for the direct cooling section 210 to enter and exit is formed between the pressure plate 400 and the ice tray 320. When the pressure plate 400 is in the second state, the pressure plate 400 presses the direct cooling section 210 against the ice tray 320.

[0248] The pressure plate 400 presses the direct cooling section 210 against the ice tray 320 so that the direct cooling section 210 remains in contact with the ice tray 320, ensuring that the direct cooling section 210 directly cools the ice tray 320, thereby ensuring the ice-making efficiency of the ice tray 320.

[0249] It should be noted that, to ensure the direct cooling section 210 can enter and exit the ice-making chamber assembly 300, during the refrigerator manufacturing stage, before the ice-making chamber assembly 300 is installed onto the refrigerator liner 100, the pressure plate 400 is in the first state. After the ice-making chamber assembly 300 is installed onto the refrigerator liner 100, the control mechanism 500 switches the pressure plate 400 to the second state. During after-sales maintenance, before removing the ice-making chamber assembly 300, the pressure plate 400 is in the second state. Therefore, the control mechanism 500 needs to be used to switch the pressure plate 400 back to the first state before removing the ice-making chamber assembly 300 from the refrigerator liner 100. After inspecting the ice-making chamber assembly 300, the pressure plate 400 is in the first state. Then, the ice-making chamber assembly 300 is installed onto the refrigerator liner 100, and the control mechanism 500 switches the pressure plate 400 back to the second state.

[0250] Therefore, to ensure the proper installation of the pressure plate 400, it is necessary to install the pressure plate 400 after the direct cooling section 210 has been inserted into the ice-making chamber assembly 300. However, the space occupied by the pressure plate 400 is relatively small. The pressure plate 400 is typically installed with bolts after the ice tray 320 and the direct cooling section 210 have been installed, resulting in limited installation space, high operational difficulty, and low installation efficiency. Disassembling the ice-making chamber assembly 300 also requires removing the pressure plate 400 first, followed by separating the direct cooling section 210 and the ice tray 320, again presenting the same problems of limited installation space, high operational difficulty, and low installation efficiency. In this embodiment, because the first housing 310 and the ice tray 320 are integrated into a single structure, the installation space for the pressure plate 400 is even smaller, making installation even more difficult.

[0251] In this embodiment, by setting a control mechanism 500 to control the two states of the pressure plate 400, the pressure plate 400 can be integrated into the ice-making chamber assembly 300 during modular assembly. The pressure plate 400 is installed and removed along with the ice-making chamber assembly 300 as a whole, which not only facilitates the installation and removal of the pressure plate 400, but also facilitates the installation and removal of the ice-making chamber assembly 300, reducing the difficulty of installation and removal and simplifying the operation of the staff.

[0252] In the prior art, the pressure plate 400 is usually installed separately after the ice tray 320 and the refrigeration pipe are installed. The pressure plate 400 is then sent to the installation position and installed in place by bolts. However, the presence of the ice tray 320, the refrigeration pipe and the first housing 310 here will result in a small installation space, making it difficult for workers to operate and resulting in low installation efficiency.

[0253] In this embodiment, by setting up a control mechanism 500, the control mechanism 500 can install the pressure plate 400 into place without the need for workers to manually install the pressure plate 400 into place with bolts, thereby reducing the difficulty of operation for workers and improving installation efficiency.

[0254] In some embodiments, the control mechanism 500 includes a cam 510, a rotating shaft 540, and a connecting block 520. The connecting block 520 is disposed on the ice tray 320 and has a movable groove 521. The movable groove 521 has a lateral third opening 522. The cam 510 is connected to the rotating shaft 540, which is movably disposed in the movable groove 521. The cam 510 has a first posture and a second posture, and the cam 510 rotates to switch between the first posture and the second posture.

[0255] When the cam 510 is in the first posture, the rotating shaft 540 can drive the cam 510 from the third opening 522 into the movable groove 521, and the pressure plate 400 is in the first state; when the cam 510 is in the second posture, the cam 510 presses against the pressure plate 400, forcing the pressure plate 400 to switch to the second state.

[0256] The connecting block 520 is fixedly connected to the bottom of the ice tray 320. The cam 510 rotates on the connecting block 520 via the rotating shaft 540, while the connecting block 520 itself remains stationary.

[0257] In this embodiment, the connecting block 520 and the ice tray 320 are separate components. In other embodiments, the connecting block 520 may be integrally formed with the ice tray 320.

[0258] Before installing the ice-making chamber assembly 300, the pressure plate 400 is installed under the ice tray 320 via the connecting block 520. When the cam 510 is in the first posture, the pressure plate 400 is not pressed against the bottom of the ice tray 320; instead, the pressure plate 400 rests on the cam 510. Therefore, the gap between the pressure plate 400 and the ice tray 320 is relatively large, forming 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, gradually switching from the first posture to the second posture. The cam 510 lifts the pressure plate 400, reducing the gap between the pressure plate 400 and the ice tray 320. This allows the cam 510 to drive the pressure plate 400 to press the direct cooling section 210 against the ice tray 320, thus completing the installation of the ice maker.

[0259] Similarly, when removing the ice chamber assembly 300, since the cam 510 is in the second posture, the cam 510 needs to be rotated first, so that the cam 510 gradually switches from the second posture to the first posture. The pressure plate 400 is gradually lowered, and the gap between the pressure plate 400 and the ice tray 320 becomes larger, forming the first channel 330 again for the direct cooling section 210 to be extracted.

[0260] In this embodiment, please refer to Figures 24-26The cam 510 includes a cam body 511 and a large circular portion 512, a small circular portion 513, and a handle 530 disposed on the cam body 511. The large circular portion 512 and the small circular portion 513 are respectively disposed on both sides of the cam body 511. When the cam 510 switches from the first posture to the second posture, the cam 510 rotates until the small circular portion 513 pushes up the pressure plate 400. The cam 510 continues to rotate until the small circular portion 513 presses against the pressure plate 400 near the edge of the handle 530. The pressure plate 400 prevents the handle 530 from moving further, and the cam 510 is in the second posture.

[0261] Please refer to Figures 27-28 The cam 510 lifts the pressure plate 400 by means of the small circular portion 513, but the small circular portion 513 is not always in contact with the pressure plate 400. When the cam 510 is in the first posture, the small circular portion 513 is facing to the side. At this time, the pressure plate 400 is not lifted, but rests on the cam body 511. As the cam 510 rotates, the cam 510 gradually changes from the first posture to the second posture. During this process, the small circular portion 513 gradually changes from not contacting the pressure plate 400 to one side edge of the small circular portion 513 contacting and lifting the pressure plate 400, until the cam 510 is in the second posture, and the pressure plate 400 also contacts the other side edge of the small circular portion 513.

[0262] When the cam 510 is in the second posture, the small round part 513 will still press against the pressure plate 400, ensuring that the pressure plate 400 presses the direct cooling section 210 against the ice tray 320.

[0263] With this structure, when the cam 510 is in the second posture, the position of the pressure plate 400 can be stabilized, ensuring that the direct cooling section 210 abuts against the ice grid 320. Moreover, the transition between the first and second postures can also be smooth.

[0264] Both the small circular portion 513 and the large circular portion 512 can be set to be arc-shaped. The arc length and central angle of the large circular portion 512 and the small circular portion 513 can be set to be different. Both sides of the small circular portion 513 can be set to be planes.

[0265] The angle between the line connecting the centers of the large circular portion 512 and the small circular portion 513 and the extending direction of the handle 530 is denoted as ∠a, and the rotation angle of the cam 510 when switching from the first posture to the second posture is denoted as ∠a, satisfying: ∠a>∠a.

[0266] Since the handle 530 is to be rotated close to the pressure plate 400 when rotating the cam 510, and ∠a>∠a is set so that the handle 530 can pass the highest point of the cam 510 during the rotation, that is, the edge of the small circle 513 is pressed against the pressure plate 400.

[0267] When the cam 510 is in the second posture, the highest point of the cam 510 and the handle 530 are located on opposite sides of the contact position between the cam 510 and the pressure plate 400. In this situation, the cam 510 tends to continue rotating along the rotation direction from the first posture to the second posture, and the handle 530 also tends to move in this rotation direction. However, the presence of the pressure plate 400 blocks the handle 530, preventing it from continuing to rotate, thus limiting the continued rotation of the cam 510 and achieving a locked state. The pressure plate 400 can maintain the state of pressing the direct cooling section 210 against the ice tray 320. Without external force intervention, the cam 510 cannot switch from the second posture to the first posture.

[0268] The connecting block 520 is also provided with a first limiting part 523, which is located on the side of the movable groove 521 away from the ice tray 320. When the cam 510 is in the second posture, the first limiting part 523 can cooperate with the large circular part 512 to prevent the rotating shaft 540 from leaving the movable groove 521 from the third opening 522.

[0269] Since the connecting block 520 has a lateral third opening 522, allowing the rotating shaft 540 to enter the movable groove 521 through the third opening 522, it is necessary to prevent the cam 510 from disengaging from the movable groove 521 through the third opening 522 when it lifts the pressure plate 400.

[0270] When the cam 510 is in the first posture, the first limiting part 523 will not engage with the large circular part 512. Similarly, the handle 530, the small circular part 513, and the cam body 511 will not engage with the first limiting part 523. In other words, the cam 510 can avoid the first limiting part 523, allowing the rotating shaft 540 to enter and exit the movable groove 521 through the third opening 522. However, when the cam 510 is in the second posture, the large circular part 512 engages with the first limiting part 523. That is, on the path away from the movable groove 521, the first limiting part 523 blocks the large circular part 512, restricting the cam 510 to remain within the movable groove 521, preventing the rotating shaft 540 from leaving the movable groove 521.

[0271] The radius of the large circular portion 512 is denoted as R mm, and the radius of the small circular portion 513 is denoted as R mm; the first limiting portion 523 includes an extension section 5231 and a limiting section 5232. The extension section 5231 extends along the extension direction of the movable groove 521, and the limiting section 5232 is disposed at one end of the extension section 5231 near the third opening 522. The limiting section 5232 is arc-shaped, and the radius of the limiting section 5232 is denoted as R mm.

[0272] The limiting segment 5232 is closer to the third opening 522 than the extension segment 5231, and thus is closer to the cam 510 located at the third opening 522, so that it can engage with the large circle portion 512 at this location.

[0273] In the direction perpendicular to the line connecting the centers of the large circular portion 512 and the small circular portion 513, the length of the cam body 511 is denoted as L mm; the plane containing the axis of the rotating shaft 540 is denoted as the reference plane 550, the reference plane 550 is parallel to the extension direction of the movable groove 521, the distance between the reference plane 550 and the end of the limiting segment 5232 is denoted as L mm, and the distance between the reference plane 550 and the extension segment 5231 is denoted as L mm; satisfying: L>R, R>R, R>L, L>L / , R>L.

[0274] This configuration limits the distance the cam 510 can move toward the third opening 522, preventing the cam 510 from moving within the movable groove 521 and becoming dislodged at the third opening 522, thus ensuring that the direct cooling section 210 is stably pressed against the ice tray 320 by the pressure plate 400.

[0275] In some embodiments, please refer to Figures 21-23 The bottom of the ice tray 320 is provided with a receiving groove 321 for accommodating the direct cooling section 210, and the pressure plate 400 is also provided with a support plate 410 for pressing the direct cooling section 210; when the pressure plate 400 is in the second state, the support plate 410 presses the direct cooling section 210 into the receiving groove 321.

[0276] The direct cooling section 210 is U-shaped, and the shape of the receiving groove 321 at the bottom of the ice tray 320 also matches the direct cooling section 210. When the direct cooling section 210 is inserted to the correct position, the direct cooling section 210 can be pressed into the receiving groove 321 by the pressure plate 400 and achieve direct contact with the ice tray 320.

[0277] The arrangement of the tray 410 allows the pressure plate 400 to exert a more uniform force on the direct cooling section 210, ensuring that the portion of the direct cooling section 210 corresponding to the receiving groove 321 can enter the receiving groove 321.

[0278] The tray 410 can be configured in multiple ways and distributed at different positions in the direct cooling section 210.

[0279] In some embodiments, the tray 410 includes a connecting portion 411 and an abutting portion 412. The connecting portion 411 is connected to the pressure plate 400, and the abutting portion 412 is disposed on the connecting portion 411 and is used to press against the refrigeration pipe.

[0280] The connecting part 411 allows the support plate 410 to be mounted on the pressure plate 400, so that the support plate 410 can move with the movement of the pressure plate 400. When the pressure plate 400 presses against the direct cooling section 210, the abutting part 412 abuts against the direct cooling section 210. Since the direct cooling section 210 is a tube, the abutting part 412 can be configured to match the shape of the direct cooling section 210.

[0281] The abutting part 412 extends from one side of the connecting part 411, so the abutting part 412 can deform to a certain extent. This can prevent the abutting part 412 from applying too much pressure to the direct cooling section 210 after it is pressed against the ice tray 320, thereby providing a certain degree of protection for the direct cooling section 210.

[0282] In some embodiments, a support plate 413 is also provided on the pressure plate 400, with one end of the support plate 413 away from the pressure plate 400 located on the side of the support plate 410 facing the pressure plate 400.

[0283] The support plate 413 can limit the connection part 411. On the one hand, the support plate 413 can position the connection part 411 for the installation of the support plate 410. On the other hand, the support plate 413 can also prevent the support plate 410 from deforming too much.

[0284] Each of the trays 410 may be provided with a pair of support plates 413, which are provided at both ends of the corresponding tray 410.

[0285] In some embodiments, the pressure plate 400 is provided with a first through hole 414, the connecting block 520 passes through the first through hole 414, and the handle 530 and the cam 510 are both located on the side of the pressure plate 400 away from the refrigeration pipe.

[0286] Since the connecting block 520 needs to connect both the pressure plate 400 and the ice tray 320, and the pressure plate 400 needs to press against the direct cooling section 210, the cam 510 is positioned on the side of the pressure plate 400 away from the ice tray 320. The handle 530 also needs to be positioned on the side of the pressure plate 400 away from the ice tray 320. To connect the cam 510 and the handle 530, a first through hole 414 is provided on the pressure plate 400, allowing the connecting block 520 to pass through the first through hole 414. This results in a portion of the connecting block 520 being located on the side of the pressure plate 400 away from the ice tray 320, thus enabling the installation of the cam 510 and the handle 530.

[0287] In some embodiments, please refer to Figure 29 The pressure plate 400 has a recess 415 on its surface away from the cooling pipe. The first through hole 414 is located in the recess 415. When the cam 510 is in the second posture, the handle 530 is fully inserted into the recess 415.

[0288] Since other components will be installed on the side of the pressure plate 400 away from the ice tray 320, the recess 415 is provided to facilitate the installation of other components and reduce the occupation of the empty space of the ice chamber 350. The handle 530 can be hidden when the ice chamber assembly 300 is installed.

[0289] In some embodiments, please refer to Figures 30-32 The refrigerator also includes a mounting plate 600 and an insulation clip 700.

[0290] The mounting plate 600 is installed on the outer wall of the box liner 100. The mounting plate 600 is provided with a surrounding plate 620 forming a second channel 610. The surrounding plate 620 is inserted into the first opening 110. The second channel 610 is for the direct cooling section 210 to pass through.

[0291] The second channel 610 allows the direct cooling section 210 to pass through the mounting plate 600 and enter the interior of the liner 100.

[0292] In this embodiment, the direct cooling section 210 passes through the center of the second channel 610; in other words, at least a portion of the direct cooling section 210 extends into the liner 100 from the center of the enclosure 620.

[0293] The heat-insulating clamp 700 includes a first clamp 710 and a second clamp 720. The first clamp 710 and the second clamp 720 are closed and disposed in the second channel 610. The surrounding plate 620 restricts the position of the first clamp 710 and the second clamp 720. The first clamp 710 and the second clamp 720 also jointly clamp and wrap the direct cooling section 210 to restrict the positional change of the direct cooling section 210 at the first opening 110.

[0294] In this embodiment, both the first clip 710 and the second clip 720 are foam clips, and the first clip 710 and the second clip 720 are arranged vertically. The first clip 710, the second clip 720, and the surrounding plate 620 restrict the positional change of the direct cooling section 210 at the opening.

[0295] The insulation clip 700 reduces heat exchange between the direct cooling section 210 and the environment outside the ice maker assembly, and reduces the impact of the path arrangement of the direct cooling section 210 on the cooling capacity of the ice maker assembly.

[0296] In the prior art, the direct cooling section 210 is pre-installed on the liner 100, and a portion of the direct cooling section 210 is used to cool the ice maker assembly. Currently, there are two installation methods: one is to install each component of the ice maker assembly individually into the liner 100; the other is to integrate at least a portion of the components of the ice maker assembly into a single integrated structure, i.e., modular installation of the ice maker assembly, with this integrated structure directly installed into the liner 100. Both installation methods require coordination with the portion of the direct cooling section 210 used for cooling the ice maker assembly, therefore, it is necessary to minimize the shaking of the direct cooling section 210.

[0297] In this embodiment of the refrigerator, since the part of the direct cooling section 210 used to cool the ice maker assembly is not integrated with the ice maker assembly, and the direct cooling section 210 is pre-installed in the liner 100, it is necessary to keep the direct cooling section 210 from shaking when installing the ice maker assembly, that is, to restrict the position of the direct cooling section 210 to ensure the smooth installation of the ice maker assembly.

[0298] The mounting plate 600 and the insulation clamp 700 are configured to simultaneously limit the direct cooling section 210, thereby restricting the positional change of the direct cooling section 210 at the opening and keeping the direct cooling section 210 from shaking, thus ensuring the smooth installation of the ice maker assembly.

[0299] During installation, the first clip 710 and the second clip 720 can be installed on the direct cooling section 210 first, then the first clip 710, the second clip 720 and the direct cooling section 210 can be inserted into the channel to form a whole. Then this whole can be inserted into the opening from the outside of the box liner 100 until the mounting plate 600 is installed on the outer wall of the box liner 100.

[0300] In the prior art, for ice maker components that do not have their own cooling pipes, each component of the ice maker component, including the insulation clip 700, needs to be installed one by one. However, for ice maker components that have their own cooling pipes, the insulation clip 700 is integrated into the ice maker component when the cooling pipes are integrated into the ice maker component. In this embodiment, since the direct cooling section 210 needs to be inserted into the ice maker component, the installation of the insulation clip 700 is inconvenient.

[0301] In this embodiment, the insulation component and the direct cooling section 210 are pre-installed on the inner box 100, thereby solving this problem.

[0302] In some embodiments, the direct cooling section 210 has a positioning part 211, which is located between the first clamp 710 and the second clamp 720, and is clamped and wrapped by the first clamp 710 and the second clamp 720.

[0303] The positioning part 211 allows the operator to determine the positions where the first clip 710 and the second clip 720 should clamp during installation.

[0304] The positioning part 211 is a section of bent pipe on the direct cooling section 210. In other embodiments, it may also be set to other shapes to distinguish it from the parts on the direct cooling section 210 other than the positioning part 211.

[0305] In some embodiments, the first clamp 710 is provided with a first limiting boss 711, and the second clamp 720 is provided with a first mating groove 721. The first limiting boss 711 is inserted into the first mating groove 721 to limit the relative position of the first clamp 710 and the second clamp 720.

[0306] When the first limiting boss 711 is inserted into the first mating groove 721, and the first clip 710 and the second clip 720 are inserted into the surrounding plate 620, the relative positions of the first clip 710 and the second clip 720 are restricted, and the first clip 710 and the second clip 720 will not shift even when the first clip 710 and the second clip 720 are inserted into the second channel 610.

[0307] Two first limiting protrusions 711 are provided along the extension direction of the second channel 610. The two first limiting protrusions 711 are provided at both ends of the first clamp 710. Two first mating grooves 721 are also provided, and the second mating grooves 722 are also provided at both ends of the second clamp 720.

[0308] In this embodiment, the two first limiting protrusions 711 extend to both ends of the first clamp 710, and the second mating groove 722 also extends to both ends of the second clamp 720.

[0309] In some embodiments, the first clamp 710 is provided with a second limiting boss 712, and the second clamp 720 is provided with a second mating groove 722. The second limiting boss 712 is inserted into the second mating groove 722. The second limiting boss 712 is provided corresponding to the positioning part 211 to limit the relative position of the positioning part 211 and the heat preservation clamp 700.

[0310] The second limiting boss 712 is inserted into the second mating groove 722, which can limit the position of the direct cooling section 210 relative to the first clamp 710 and the second clamp 720, and prevent the direct cooling section 210 from being displaced from the first clamp 710 or the second clamp 720.

[0311] In this embodiment, since the positioning part 211 is a section of bent pipe, the first limiting boss 711 is provided at the bend, and the bend surrounds a portion of the outer peripheral surface of the first limiting boss 711 to form a state in which the bend hooks onto the second limiting boss 712, thereby limiting the relative position of the positioning part 211 and the heat preservation clamp 700.

[0312] In some embodiments, please refer to Figures 33 The mounting plate 600 includes a first fixing plate 630 and a second fixing plate 640 arranged vertically. Please refer to... Figures 34-37 The first fixing plate 630 has a first notch 631 extending to its edge at one end, and the second fixing plate 640 has a second notch 641 extending to its edge at one end. The first notch 631 and the second notch 641 together form a fixing hole 650 through which the direct cooling section 210 passes. The surrounding plate 620 is arranged around the fixing hole 650, and the first notch 631 and the second notch 641 together clamp the direct cooling section 210 to limit the positional change of the direct cooling section 210 at the opening.

[0313] The first fixing plate 630 and the second fixing plate 640 are arranged vertically, so the first notch 631 is actually set on the bottom edge of the first fixing plate 630, and the second notch 641 is actually set on the top edge of the second fixing plate 640.

[0314] The first fixing plate 630 and the second fixing plate 640 are configured to cooperate with each other so that they together form a fixing hole 650. The two plates together clamp the direct cooling section 210, which allows them to simultaneously limit the position of the direct cooling section 210 at the opening, thereby preventing the direct cooling section 210 from shaking and ensuring the smooth installation of the ice maker assembly.

[0315] A portion of the enclosure 620 is disposed on the first fixing plate 630, and another portion of the enclosure 620 is disposed on the second fixing plate 640. After the first fixing plate 630 and the second fixing plate 640 are assembled, the enclosure 620 closes to form the second channel 610.

[0316] During installation, the first notch 631 of the first fixing plate 630 can be positioned on the direct cooling section 210, and the second notch 641 of the second fixing plate 640 can be positioned on the direct cooling section 210 and the first notch 631 respectively. Then, the direct cooling section 210 with the first clamp 710 and the second clamp 720 installed can be inserted into the opening from the outside of the box liner 100 until the first fixing plate 630 and the second fixing plate 640 are installed on the outer wall of the box liner 100.

[0317] A second limiting part 632 is provided on the first fixing plate 630. The second limiting part 632 is located at a part of the edge of the first fixing plate 630 and is hung on the outer wall of the box liner 100.

[0318] The ice maker assembly is located at one corner of the top of the container 100, so the first opening 110 is also located near one corner of the top of the container 100.

[0319] The second limiting part 632 is disposed on the top edge and side edge of the first fixing plate 630, forming a bent plate shape. By providing the second limiting part 632, the first fixing plate 630 can be hooked onto the top wall of the cabinet liner 100. The cooperation between the second limiting part 632 and the side wall is used to position the first fixing plate 630, thereby hooking the first fixing plate 630 onto the outer wall of the cabinet liner 100, and the position of the direct cooling section 210 will also be more stable. After the refrigerator foaming treatment, the foam layer can hold the first fixing plate 630 and the second fixing plate 640 against the outer wall of the cabinet liner 100, thus achieving fixation.

[0320] In some embodiments, the first fixing plate 630 is provided with a first protrusion 633, which is disposed on a portion of the edge of the fixing hole 650, and the second fixing plate 640 is provided with a second protrusion 642, which is disposed on a portion of the edge of the fixing hole 650. The first protrusion 633 and the second protrusion 642 together clamp the direct cooling section 210.

[0321] The first protrusion 633 is equivalent to a portion of the edge of the fixing hole 650 being thickened, and the second protrusion 642 is the same. The arrangement of the first protrusion 633 and the second protrusion 642 can increase the contact area with the direct cooling section 210, reduce the pressure on the surface of the direct cooling section 210, and can clamp the direct cooling section 210 more stably. It can also prevent the edge of the fixing hole 650 from being too narrow and causing damage to the surface of the direct cooling section 210.

[0322] The first protrusion 633 and the second protrusion 642 can be disposed on the same side of the fixing hole 650 or on different sides of the fixing hole 650. The first protrusion 633 can be disposed on one side of the first fixing plate 630 or on both sides of the first fixing plate 630. Similarly, the second protrusion 642 can be disposed on one side of the second fixing plate 640 or on both sides of the second fixing plate 640.

[0323] In some embodiments, the bottom of the first fixing plate 630 is further provided with a first overlapping portion 634, and the first notch 631 is provided on the first overlapping portion 634. The top of the second fixing plate 640 is further provided with a second overlapping portion 643, and the second notch 641 is provided on the second overlapping portion 643. The first overlapping portion 634 and the second overlapping portion 643 overlap each other.

[0324] The first overlapping portion 634 and the second overlapping portion 643 can be arranged in a front-to-back order according to actual needs. In other words, the first overlapping portion 634 and the second overlapping portion 643 can be arranged one after the other, or the second overlapping portion 643 and the first overlapping portion 634 can be arranged one after the other.

[0325] By setting the first overlapping portion 634 and the second overlapping portion 643, the first fixing plate 630 and the second fixing plate 640 can be restricted to each other to prevent them from falling off due to installation errors. Moreover, the first overlapping portion 634 and the second overlapping portion 643 can also be positioned to each other, making it easier for them to form the fixing hole 650.

[0326] In some embodiments, the first fixing plate 630 and the second fixing plate 640 are snapped together.

[0327] By setting the first fixing plate 630 and the second fixing plate 640 to be snapped together, the integrity of the first fixing plate 630, the second fixing plate 640 and the fixing hole 650 can be improved. When the direct cooling section 210 is inserted into the opening from the outside of the box liner 100, the structure with high integrity is easier for the staff to operate.

[0328] In some embodiments, please refer to Figures 38-40 The enclosure 620 is provided with a third through hole 621, and a cantilever 622 is provided on the edge of the third through hole 621. The first clamp 710 or the second clamp 720 is provided with a groove 730 at the position corresponding to the cantilever 622. A buckle part 623 is also provided on the edge of the third through hole 621. The cantilever 622 cooperates with the buckle part 623 so that the cantilever 622 abuts against the groove 730.

[0329] The cantilever 622 can move at the third through hole 621. When the cantilever 622 is engaged with the buckle 623 and pressed against the groove 730, the cantilever 622 can press against the first clamp 710 or the second clamp 720, increasing the relative force between the first clamp 710 and the second clamp 720, thereby fixing the first clamp 710 and the second clamp 720.

[0330] In some embodiments, please refer to Figure 41 and Figure 42 The enclosure 620 is provided with a third through hole 621, and a cantilever 622 is provided on the edge of the through hole; the heat preservation clamp 700 also includes a fixing pin 740, which passes through the first clamp 710, the second clamp 720 and the cantilever 622 so that the cantilever 622 abuts against the first clamp 710 or the second clamp 722.

[0331] The cantilever 622 is movable at the through hole. After the fixing pin 740 is set, the fixing pin 740 can press on the cantilever 622, so that the cantilever 622 can press against the first clamp 710 or the second clamp 720, thereby fixing the first clamp 710 and the second clamp 720.

[0332] Specifically, a screw is provided at the end of the fixing pin 740 away from the cantilever 622, and the screw can help the fixing pin 740 press the cantilever 622.

[0333] In addition, a protrusion is provided on the side wall of the fixing pin 740, and a notch corresponding to the protrusion is provided at the corresponding position of the enclosure 620. The protrusion is located in the notch, which can play a limiting role when tightening the screw, making it convenient for the operator to operate.

[0334] The mounting plate 600 is snapped onto the outer wall of the box liner 100.

[0335] The mounting plate 600 moves to the outer wall of the container liner 100, and the surface of the mounting plate 600 fits against the outer wall of the container liner 100. A snap-fit ​​structure is provided on the container liner 100 to engage with the mounting plate 600, allowing the mounting plate 600 to be snapped onto the outer wall of the container liner 100.
