[0042] The present patent will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present patent, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0043] Reference Figure 1 This application provides a refrigeration device 100. The refrigeration device 100 may include a housing 101. A storage compartment 102 may be formed inside the housing 101. The storage compartment 102 has an opening through which a user can retrieve or place items.

[0044] In this application, the height direction of the refrigeration device 100 is the up-down direction, the depth direction of the storage room 102 is the front-back direction, and the width direction of the refrigeration device 100 is the left-right direction. The opening of the storage room 102 faces forward.

[0045] Reference Figure 1 and Figure 2The refrigeration equipment 100 may include a door 1. The door 1 is connected to the housing 101. The door 1 is used to open and close the storage compartment 102. The wall of the door 1 is provided with a receiving cavity 41, which is recessed into the door 1.

[0046] Reference Figures 2 to 5 The refrigeration equipment 100 may include a water box 2. The water box 2 is removably mounted on the door 1. The water box 2 includes a main body 21 and a water outlet 22. A water storage space 211 is formed inside the main body 21. The water outlet 22 includes a first end 221, a second end 222, and a water outlet channel 223 connecting the first end 221 and the second end 222. The first end 221 is located inside the water storage space 211, and the second end 222 is located outside the main body 21. Water in the water storage space 211 enters the water outlet channel 223 through the first end 221 and flows out of the water outlet channel 223 through the second end 222.

[0047] The refrigeration equipment 100 may include a water-requiring structure. The water-requiring structure may be installed in the door 1 or in the cabinet 101.

[0048] Reference Figures 5 to 7 The refrigeration equipment 100 may include a channel component 3. The channel component 3 includes a third end 31, a fourth end 32, and a water flow channel 33 connecting the third end 31 and the fourth end 32. At least the third end 31 of the channel component 3 is disposed within the receiving cavity 41, and the fourth end 32 is used to connect to the water-requiring structure. When the water box 2 is placed on the door 1, the second end 222 is located within the receiving cavity 41 and connected to the third end 31. The water box 2 supplies water to the water-requiring structure via the water outlet channel 223 and the water flow channel 33.

[0049] This application achieves efficient connection and convenient operation of the water supply system by setting a receiving cavity 41 on the door body 1 of the refrigeration equipment 100 and cooperating with the water box 2 and the channel component 3. The receiving cavity 41 on the door body 1 allows the second end 222 (the outlet end) of the water box 2's outlet section 22 to be easily inserted into the receiving cavity 41 and directly connected to the third end 31 (the inlet end) of the channel component 3. This design simplifies the installation steps of the water box 2, eliminating the need for complex docking operations. Simply placing the water box 2 on the door body 1 and inserting the outlet end 22 into the receiving cavity 41 of the door body 1 completes the connection, reducing operational difficulty and time costs.

[0050] The receiving cavity 41 provides a stable structure to fix the water outlet end of the water outlet 22 and the water inlet end of the channel 3 of the water box 2, preventing the connection between the water outlet end of the water outlet 22 and the water inlet end of the channel 3 from becoming loose or disconnected due to vibration or improper operation during use. By fixing the position of the interface between the water outlet 22 and the water flow channel 33 by the receiving cavity 41, smooth water flow can be ensured, water leakage or interruption can be avoided, and the reliability of water supply from the water box 2 can be improved.

[0051] The recessed design of the receiving cavity 41 allows the water outlet end of the water outlet 22 of the water box 2 to be embedded inside the door body 1, avoiding the exposure of the water outlet end of the water outlet 22. It also prevents external environment such as dust or dirt from contaminating the water outlet 22 and the channel component 3, ensuring the cleanliness of the water supplied from the water box 2 to the channel component 3.

[0052] Because the water tank 2 is designed to be removable, users can easily remove it for cleaning, maintenance, or replacement of the water source in the water storage space 211 without disassembling the entire water supply system. The placement of the channel component 3 within the receiving cavity 41 also facilitates inspection and repair by the user, reducing the complexity of maintenance work.

[0053] The direct connection between the water outlet channel 223 and the water flow channel 33 forms a simple water flow path, ensuring a smooth and efficient water supply process from the water storage space 211 of the water box 2 to the water-requiring structure. This reduces water flow resistance and energy loss, improves water supply efficiency, and lowers energy consumption during the water supply process. The receiving cavity 41 can limit the water outlet end of the water outlet section 22, allowing the second end 222 of the water outlet section 22 to accurately connect with the channel component 3, reducing connection errors, preventing water leakage, and improving the convenience of installing the water box 2 on the door 1.

[0054] Reference Figures 5 to 7 In one embodiment of this application, the refrigeration device 100 includes a mounting member 4 installed on the door body 1, and the receiving cavity 41 is formed inside the mounting member 4. In other embodiments, the receiving cavity 41 may also be formed by a direct inward recess from the wall of the door body 1.

[0055] Reference Figures 2 to 8 In one embodiment of this application, the main body 21 includes a longitudinal sidewall. A limiting groove 214 is provided on the longitudinal sidewall. The limiting groove 214 extends longitudinally. An opening is present at the lower end of the limiting groove 214. A limiting block 11 is provided on the door body 1. The limiting block 11 can be inserted into the limiting groove 214 through the opening at the lower end of the limiting groove 214.

[0056] The water outlet channel 223 includes a downward opening formed at the second end 222. The water flow channel 33 includes an upward opening formed at the third end 31. When the lower opening of the limiting groove 214 is aligned with and flush with the top wall of the limiting block 11, the second end 222 is located in the receiving cavity 41, and the downward opening of the second end 222 is aligned with and spaced apart from the upward opening of the third end 31 by a predetermined distance.

[0057] This application achieves precise installation of the water box 2 and the door 1, as well as reliable connection between the water outlet 22 and the channel component 3, through the cooperative design of the limiting groove 214 and the limiting block 11. The limiting groove 214 extends longitudinally, and its lower opening engages with the limiting block 11, allowing the water box 2 to slide precisely into the door 1 from top to bottom. The cooperation between the limiting block 11 and the limiting groove 214 restricts the lateral movement of the water box 2, thereby ensuring the lateral position stability of the water box 2 and preventing the water box 2 from shifting.

[0058] When the lower opening of the limiting groove 214 is aligned and flush with the top wall of the limiting block 11, the downward opening of the second end 222 of the water outlet 22 is aligned with the upward opening of the third end 31 of the channel component 3, separated by a preset distance. This design allows the limiting groove 214 and the limiting block 11 to engage first, followed by the engagement of the water outlet 22 and the channel component 3. The insertion of the limiting groove 214 and the limiting block 11 first fixes the lateral position of the water box 2, ensuring that the downward opening of the second end 222 of the water outlet 22 is aligned with the upward opening of the third end 31 of the channel component 3. Subsequently, the guiding effect of the limiting groove 214 and the limiting block 11 ensures precise vertical alignment between the second end 222 of the water outlet 22 and the third end 31 of the channel component 3. This design effectively avoids leakage or connection failure caused by inaccurate alignment, improving the reliability of the water supply system.

[0059] During the insertion of the limiting block 11 into the limiting groove 214, the limiting groove 214 guides the water box 2 to move along a fixed trajectory as it descends. This guiding function prevents possible shaking or displacement of the water box 2 during installation, ensuring a smooth connection between the water outlet 22 and the channel component 3. The user simply inserts the water box 2 into the door 1 from top to bottom. Through the cooperation of the limiting block 11 and the limiting groove 214, the water outlet 22 of the water box 2 can smoothly connect with the channel component 3. No additional connection adjustments are required during installation. The limiting groove 214 and the limiting block 11 automatically guide the installation and connection of the water box 2, greatly simplifying the operation process and improving installation convenience.

[0060] The removable design of water box 2, combined with the cooperation of limiting block 11 and limiting groove 214, allows users to easily disassemble water box 2 for cleaning or maintenance without worrying about inaccurate reinstallation. Limiting groove 214 provides a clear guide trajectory, ensuring accurate repositioning every time. This precise installation and docking design effectively avoids the risk of water leakage during water supply from water box 2, ensuring the operational stability of the water supply system. Simultaneously, it reduces the possibility of damage to the refrigeration equipment 100 due to improper user operation, thus improving the safety of the refrigeration equipment 100.

[0061] Reference Figures 6 to 8In one embodiment of this application, the water flow channel 33 includes an opening formed at the third end 31. The refrigeration device 100 includes an elastic element 5. The elastic element 5 may include an elastic sheet 51 for closing the opening at the third end 31. The elastic element 5 may be installed within a receiving cavity 41. The elastic sheet 51 has a self-sealing opening 52. The self-sealing opening 52 may be cross-shaped, straight, or other shapes. When the second end 222 applies force to the elastic sheet 51, the elastic sheet 51 undergoes elastic deformation and opens the self-sealing opening 52 so that the second end 222 can pass through the self-sealing opening 52 and connect to the third end 31. When the second end 222 disengages from the elastic sheet 51, the elastic sheet 51 returns to its original position under its own elastic force and closes the self-sealing opening 52. The elastic sheet 51 may be made of an elastic plastic material, such as silicone.

[0062] By setting an elastic sheet 51 at the third end 31 of the water flow channel 33 and designing a self-sealing opening 52, efficient and reliable sealing and docking functions can be achieved. The self-sealing opening 52 formed by the elastic sheet 51 remains closed when not in use, which can effectively prevent dust, impurities or other foreign objects from entering the water flow channel 33, ensuring the hygiene of the water supply.

[0063] The cross-shaped design of the self-sealing opening 52 has excellent elastic deformation characteristics, enabling it to automatically adapt and seal according to the shape and position of the second end 222. When the second end 222 is inserted, the elastic piece 51 can flexibly conform to the outer peripheral surface of the second end 222, preventing dust and other contaminants from polluting the interface between the second end 222 and the third end 31. Users can simply push the second end 222 towards or remove it from the elastic piece 51 to open and close the self-sealing opening 52 without additional manual adjustment, making operation simple and convenient.

[0064] The elastic sheet 51 is made of elastic plastic material, which has good durability, flexibility and water resistance, and is also low in cost. The high elasticity material design of the elastic sheet 51 can withstand multiple insertion and removal operations while maintaining a sealing effect. It is not easily damaged by fatigue. Even with frequent use, the elastic sheet 51 can still maintain its sealing performance, meet the long-term use requirements of the refrigeration equipment 100, and improve the overall reliability of the refrigeration equipment 100.

[0065] Reference Figures 6 to 9In one embodiment of this application, the receiving cavity 41 includes a first opening 42 and a second opening 43 located on the side of the water box 2. The second end 222 is inserted into the receiving cavity 41 through the first opening 42. The third end 31 is inserted into the receiving cavity 41 through the second opening 43. The refrigeration device 100 includes a cover plate 6 covering the second opening 43, and the refrigeration device 100 also includes a limiting member 7 disposed within the receiving cavity 41. The limiting member 7 abuts against the wall of the receiving cavity 41 and the cover plate 6. The limiting member 7 is in contact with the peripheral wall of the third end 31. The peripheral wall of the third end 31 is provided with an annular protrusion 34. The cover plate 6 is provided with a first insertion portion 61 that engages with the annular protrusion 34. The limiting member 7 is formed with a second insertion portion 71 that engages with the annular protrusion 34. This facilitates the installation of the channel member 3 and better secures the third end 31 of the channel member 3.

[0066] The receiving cavity 41 includes a first opening 42 and a second opening 43 located on the side of the water box 2. The channel component 3 is allowed to be inserted into the cavity through the second opening 43, and the water outlet 22 is allowed to be inserted into the cavity through the first opening 42. This avoids interference between the channel component 3 and the water outlet 22, reduces the complexity of the connection during installation, and facilitates the quick and correct installation of the channel component 3 and the water outlet 22.

[0067] The limiting member 7 is disposed within the receiving cavity 41 and abuts against the wall of the receiving cavity 41 and the cover plate 6, providing structural stability support for the channel member 3 and preventing the channel member 3 from shaking or shifting. The limiting member 7 is inserted into the annular protrusion 34 of the third end 31 through the second insertion part 71, further enhancing the fixation of the third end 31 of the channel member 3, ensuring the accurate position of the third end 31 of the channel member 3, and ensuring that the third end 31 is not easily loosened or displaced after installation. The cover plate 6, through the cooperation of the first insertion part 61 and the annular protrusion 34, can provide additional support and restraint for the channel member 3, further improving the fixation and limiting effect of the channel member 3 and preventing the channel member 3 from shaking or shifting.

[0068] By double-inserting and fixing the annular protrusion 34 to the cover plate 6 and the limiting groove 214 on the limiting member 7, the third end 31 of the channel member 3 can obtain stable support in both the longitudinal and transverse directions, preventing positional displacement or loosening. The limiting member 7 is in close contact with the wall of the receiving cavity 41 and the cover plate 6, effectively mitigating the impact of vibration during the operation of the refrigeration equipment 100 on the channel member 3, and extending the reliability and service life of the water supply system.

[0069] The tight fit between the annular protrusion 34 of the channel component 3 and the limiting groove 214 of the limiting component 7 and the cover plate 6 not only secures the channel component 3 but also enhances the sealing effect within the accommodating cavity 41, preventing poor connection due to loosening of the channel component 3, avoiding water leakage, and ensuring the reliability of the water supply system. The cover plate 6 also provides sealed protection for the accommodating cavity 41 and the channel component 3. Covering the second opening 43 further seals off the surrounding environment of the channel component 3, preventing dust or foreign objects from entering the accommodating cavity 41, thus improving the safety and stability of the water supply system.

[0070] The cover plate 6 covers the second opening 43, protecting the internal components and providing a convenient access for maintenance of the channel component 3. Users can easily access the channel component 3 by removing the cover plate 6, which simplifies the installation process of the limiting component 7 and the channel component 3, facilitates later maintenance and replacement, and reduces maintenance costs.

[0071] In one embodiment of this application, the refrigeration device 100 includes a sealing door for closing a first opening 42. The sealing door includes a first sealing door body 1 and a second sealing door body 1 that are symmetrical about the left and right sides of the first opening 42.

[0072] The symmetrical design of the first sealing door 1 and the second sealing door 1 helps to provide a seal on both the left and right sides of the first opening 42 simultaneously. The sealing doors further isolate the internal structure of the receiving cavity 41 from the outside environment, preventing external environmental factors such as dust and moisture from affecting the internal components of the receiving cavity 41 and ensuring cleanliness within the receiving cavity 41. The symmetrical design of the first and second sealing door 1 also facilitates the insertion of the second end 222 of the water outlet 22 into the receiving cavity 41.

[0073] Reference Figure 3 and Figure 4 , Figure 10 and Figure 11 In one embodiment of this application, the main body 21 includes a box body 212 and a cover body 213. The box body 212 has an opening at its upper end. The cover body 213 is used to close the opening at the upper end of the box body 212. The water outlet 22 includes a first water outlet 224 integrally formed with the cover body 213 and a second water outlet 225 installed on the cover body 213. The first water outlet 224 includes a second end 222 and a fifth end 226 disposed on the inner wall of the cover body 213. The second water outlet 225 includes a first end 221 and a sixth end 227 connected to the fifth end 226.

[0074] The first water outlet 224 is integrally formed with the cover 213, which reduces the number of connection points between the first water outlet 224 and the cover 213 and avoids water leakage caused by assembly errors or loose connections. The second water outlet 225 is connected to the first water outlet 224 to form a complete water outlet channel 223, which facilitates the forming of the water outlet channel 223 and reduces the complexity of processing. Since the second water outlet 225 is located inside the water box 2, and the interface between the first water outlet 224 and the second water outlet 225 is also located inside the water box 2, water leakage can be effectively prevented.

[0075] In one embodiment of this application, the second water outlet 225 is a flexible hose. The sixth end 227 is inserted into the outside of the fifth end 226. The flexible hose is inserted into the fifth end 226 of the first water outlet 224. Because the flexible material of the hose has natural conformability, a reliable sealing effect can be formed, effectively preventing water leakage at the interface between the fifth end 226 and the sixth end 227.

[0076] The sixth end 227 may have a first protrusion on its peripheral wall. The fifth end 226 may have a first locking interface on its peripheral wall that mates with the first protrusion. When the sixth end 227 is inserted into the fifth end 226, the first protrusion and the first locking interface engage to firmly lock the flexible hose to the outside of the fifth end 226, preventing loosening or detachment due to water pressure or external force. The locking structure of the first protrusion and the first locking interface not only facilitates installation but also allows users to easily disassemble the hose for cleaning or replacement when needed. It ensures stability while allowing for separation and connection with appropriate force, eliminating the need for special tools and reducing maintenance difficulty and cost.

[0077] Reference Figure 10 and Figure 11 In one embodiment of this application, the sixth end 227 may be symmetrically provided with a first protruding rib 2271 and a second protruding rib 2272 on its periphery. The inner wall of the cover 213 may be provided with a first limiting rib 2132 and a second limiting rib 2133 that are respectively inserted into the first protruding rib 2271 and the second protruding rib 2272.

[0078] The first limiting rib 2132 and the second limiting rib 2133 provided on the inner wall of the cover 213 are respectively inserted into the first protruding rib 2271 and the second protruding rib 2272. Through the symmetrical multi-point limiting structure, the connection is further prevented from loosening or displacement caused by external force, ensuring connection stability and enhancing the fixing effect between the second water outlet 225 and the cover 213.

[0079] Reference Figure 12In one embodiment of this application, a U-shaped snap-fit ​​connector 2131 may be provided on the inner wall of the water box 2. The U-shaped snap-fit ​​connector 2131 snaps onto the peripheral wall of the second water outlet 225 near the sixth end 227. The U-shaped snap-fit ​​connector 2131 can partially surround the peripheral wall of the second water outlet 225, thereby better supporting and fixing the second water outlet 225.

[0080] Reference Figure 13 and Figure 14 In one embodiment of this application, the second water outlet 225 can be a rigid pipe. The sixth end 227 is inserted into the inside of the fifth end 226. A sealing ring can be provided between the outer wall of the sixth end 227 and the inner wall of the fifth end 226. The rigid pipe design of the second water outlet 225 ensures that it is not easily deformed during equipment operation. The sealing ring between the outer wall of the sixth end 227 and the inner wall of the fifth end 226 fills the gap between them, forming a reliable sealing structure to prevent water leakage.

[0081] Reference Figure 13 and Figure 14 In one embodiment of this application, the second water outlet 225 includes an annular wall 2273 surrounding at least part of the peripheral wall of the sixth end 227. When the sixth end 227 is inserted into the fifth end 226, the peripheral wall of the fifth end 226 is located inside the annular wall 2273. A second protrusion 2261 is provided on the outer peripheral wall of the fifth end 226. A second snap-fit ​​groove 2275 that cooperates with the second protrusion 2261 is provided on the annular wall 2273. A third rib 2276 and a fourth rib 2277 are symmetrically provided on both sides of the annular wall 2273. A third limiting rib 2134 and a fourth limiting rib 2135 that are inserted into the third rib 2276 and the fourth rib 2277 are provided on the inner wall of the cover 213.

[0082] The annular wall 2273 surrounding the sixth end 227 achieves a more stable, sealed, and reliable connection. The annular wall 2273 of the second water outlet 225 partially surrounds the peripheral wall of the sixth end 227, allowing the outer wall of the fifth end 226 to embed inside the annular wall 2273, forming a covering structure that effectively prevents the connection from loosening or detaching due to external force or water pressure. The cooperation between the protruding ribs on the annular wall 2273 and the upper limit ribs on the cover 213 provides initial locking, ensuring the stability of the first step in the connection. The engagement groove on the annular wall 2273 and the protrusions on the peripheral wall of the fifth end 226 further strengthen the locking of the second water outlet 225, providing double mechanical fixation and ensuring the connection is not affected by vibration or water flow impact.

[0083] Reference Figure 15In one embodiment of this application, a third protrusion 2274 is provided on the outer wall of the sixth end 227, and a groove 2262 is provided on the outer wall of the fifth end 226. The groove 2262 includes an axial groove 22621 extending axially along the fifth end 226 and a circumferential groove 22622 extending circumferentially along the fifth end 226. The axial groove 22621 has a groove opening 22623. When the sixth end 227 is inserted axially into the fifth end 226, the third protrusion 2274 is inserted into the axial groove 22621 through the groove opening 22623. When the sixth end 227 is inserted axially into the fifth end 226 to a preset depth, the sixth end 227 is rotated, and the second protrusion 2261 enters the circumferential groove 22622.

[0084] When the sixth end 227 is inserted into the fifth end 226, the third protrusion 2274 is accurately aligned through the axial groove 22621 of the groove 2262, ensuring directional guidance and precise positioning during the insertion process. After the sixth end 227 is inserted to a preset depth, the third protrusion 2274 is rotated into the circumferential groove 22622 by rotating the sixth end 227, completing the mechanical locking and further preventing the connection from loosening or disengaging.

[0085] Through the design of the axial groove 22621 and circumferential groove 22622 of the groove 2262, and the cooperation of the third protrusion 2274 with it, this design achieves precise alignment, quick locking and strong fixation during the insertion process, improving the reliability, sealing and durability of the connection, while simplifying the installation and disassembly operations.

[0086] Reference Figure 2 and Figure 8 In one embodiment of this application, the refrigeration device 100 includes a bracket 8 disposed on the door 1. The bracket 8 is located below the limiting block 11. The bracket 8 has a placement groove 81 with an open upper end. The placement groove 81 is used to accommodate the bottom of the water box 2.

[0087] The bracket 8 is located below the limiting block 11, and its open placement slot 81 provides a stable installation position for the water box 2. The bottom of the water box 2 fits snugly against the placement slot 81, preventing displacement due to equipment vibration or external forces, thus ensuring the stability of the water box 2 and the continuity of the water supply process. Users can complete the installation simply by inserting the water box 2 into the placement slot 81 from top to bottom. The open design of the placement slot 81 also allows users to quickly remove the water box 2 for cleaning or replacement.

[0088] The placement slot 81 provides vertical support for the water box 2, while the limiting block 11 restricts the lateral movement of the water box 2. This dual stabilization mechanism prevents the water box 2 from shaking or falling off during operation, enhancing the reliability of the equipment.

[0089] Reference Figure 6 and Figure 16In one embodiment of this application, the refrigeration equipment 100 includes a water pump module 9. The water pump module 9 includes a water pump box 91, a water pump 92 disposed within the water pump box 91, a water pump outlet pipe 93 at least partially located within the water pump box 91, and a water pump inlet pipe 94 at least partially located within the water pump box 91. The water pump outlet pipe 93 is connected to the water-requiring structure, and its fourth end 32 is connected to the water pump inlet pipe 94.

[0090] The water pump module 9 is connected to the water-requiring structure via the water pump outlet pipe 93, enabling active water delivery. The water pump 92 overcomes the effects of gravity and pipe resistance, ensuring that the water supply flow and pressure meet the needs of the water-requiring structure. The water pump module 9 includes a water pump box 91, a water pump 92, and piping. All components are integrated into one module, resulting in a compact structure that facilitates installation and maintenance while reducing the space occupied by the equipment.

[0091] In one embodiment of this application, the door 1 is provided with an ice-making chamber and a distributor chamber. The water-requiring structure includes an ice-making water-requiring structure disposed in the ice-making chamber and a distributor water-requiring structure disposed in the distributor chamber. The water pump outlet pipe 93 includes an ice-making water outlet pipe 941 connected to the ice-making water-requiring structure and a distributor water outlet pipe 942 connected to the distributor water-requiring structure.

[0092] The refrigeration equipment 100 also includes an ice maker disposed within an ice-making chamber. The refrigeration equipment 100 may further include an ice storage box disposed within the ice-making chamber. The ice storage box may be disposed below the ice maker. The ice maker may include ice molds. Several ice compartments may be formed within the ice molds. The water-requiring structure for ice making may include a water inlet. The water inlet may be disposed above the ice molds and used to inject water into the ice molds. The refrigeration equipment 100 may include a cooling system for supplying cooling to the ice-making chamber. After the water inlet has injected water into the ice molds, the refrigeration system may be activated and supply cooling to the ice-making chamber, causing the water in the ice compartments to freeze into ice cubes. The refrigeration equipment 100 may further include an ice-removing structure disposed within the ice-making chamber, which may include an ice-removing lever, etc. The ice-removing structure causes the ice cubes in the ice molds to fall into the ice storage box for user use, thereby meeting the user's ice needs.

[0093] A refrigeration system may include components such as a compressor, condenser, expansion valve, and evaporator, which work together through a refrigeration cycle.

[0094] A refrigeration cycle generally includes compression, condensation, expansion, and evaporation. Compression involves the compressor compressing the refrigerant gas, heating it, and increasing its pressure. Condensation occurs when the high-pressure hot gas releases heat in the condenser, cooling the refrigerant and condensing it into a liquid. Expansion occurs when the liquid refrigerant passes through the expansion valve, its pressure decreasing, and enters the evaporator. Evaporation occurs in the evaporator when the low-pressure refrigerant absorbs heat from the surrounding environment and evaporates into a gas. This process lowers the ambient temperature. This cycle of compression, condensation, expansion, and evaporation repeats continuously, achieving a sustained cooling effect in the refrigeration equipment.

[0095] The water supply structure of the distributor can be a water tap installed inside the distributor chamber. Users can directly access water through the water tap, thus meeting their water needs.

[0096] Storage compartment 102 can be a refrigerator compartment. Refrigerator compartments are used to store most foods that require refrigeration, such as dairy products, cooked food, fruits and vegetables, and their temperature range is usually set between 3°C and 5°C.

[0097] Reference Figure 1 , Figure 6 , Figure 8 , Figure 16 In one embodiment of this application, the door body 1 includes a door shell 12 and a door liner 13 disposed opposite to each other, and a water pump box 91 is disposed between the door shell 12 and the door liner 13. The water pump box 91 has a mounting opening 911 on the door liner 13 side. The door liner 13 forms a clearance opening 14 that mates with the mounting opening 911, and a bracket 8 is disposed inside the door liner 13. The bracket 8 covers the clearance opening 14, and the door liner 13 forms a limiting block 11. The water box 2 is removably mounted inside the door liner 13, and the distributor chamber opening faces the outside of the door body 1.

[0098] The water pump box 91 is positioned between the door housing 12 and the door liner 13, making full use of the internal space of the door 1 and avoiding occupying the storage area of ​​the equipment, thus making the overall design more compact and aesthetically pleasing. The clearance opening 14 in the door liner 13 facilitates the installation and maintenance of the water pump module 9. The bracket 8 covers the clearance opening 14, providing additional support and protection for the water pump box 91 and other components, and optimizing the space layout.

[0099] Water box 2 is installed inside door liner 13, allowing users to easily remove and place it for cleaning or replacement without disassembling complex parts. The external opening design of the distributor chamber makes it more convenient for users to access water, improving the user experience. The diversion design of the water pump outlet pipe 93 ensures that water flows quickly and accurately to the ice-making chamber and the distributor chamber, shortening ice-making time and water supply waiting time.

[0100] The refrigeration equipment 100 of this application refers to a mechanical system or device used to reduce and control the temperature of an object or space. Based on its ability to reduce the temperature of a space or object, the refrigeration equipment 100 is widely used in homes, businesses, and other locations.

[0101] In one embodiment of this application, the refrigeration device 100 may refer to a refrigerator. A refrigerator is one of the most common refrigeration devices 100 in households, used to preserve food, prevent spoilage, and extend its shelf life.

[0102] In one embodiment of this application, the refrigeration equipment 100 may refer to a display case. Display cases are widely used in commercial environments, primarily for displaying and preserving food, such as beverages, cooked food, pastries, and dairy products. These devices not only maintain food at suitable temperatures but also optimize product display, attracting customers to purchase. Display cases come in various designs and structures, and can be broadly categorized into several types based on usage needs and occasions, including freestanding, tabletop, hanging, and built-in models. Display case components maintain food at safe and suitable temperatures, extending its shelf life and preventing spoilage. Their transparent design makes the food readily visible, allowing customers to easily view and select the items they want, thus improving shopping efficiency.

[0103] In one embodiment of this application, the refrigeration device 100 may refer to a freezer. Freezers are typically designed with large capacity, easy access, and a consistently low temperature environment in mind, making them ideal for storing large quantities of frozen foods, especially perishable items such as meat, seafood, frozen foods, and frozen vegetables. For users who need to store large quantities of frozen foods, such as large families, restaurant owners, or retailers, freezers provide ample storage space. Compared to refrigerators, which are opened frequently, freezers are opened less often, which helps maintain a stable internal temperature and reduces energy consumption.

[0104] In summary, the refrigeration equipment 100 of this application can solve the technical problem of inconvenient installation of the water box 2.

[0105] The technical solution of this application simplifies the installation steps of the water box 2, eliminating the need for complex docking operations. Simply place the water box 2 onto the door 1 and insert the water outlet end of the water outlet 22 into the receiving cavity 41 of the door 1 to complete the connection, reducing operational difficulty and time costs. By providing an elastic piece 51 at the third end 31 of the water flow channel 33 and designing a self-sealing opening 52, efficient and reliable sealing and docking functions can be achieved. The self-sealing opening 52 formed by the elastic piece 51 remains closed when not in use, effectively preventing dust, impurities, or other foreign objects from entering the water flow channel 33, ensuring the hygiene of the water supply. By integrally molding the first water outlet 224 with the cover 213, the number of connection points between the first water outlet 224 and the cover 213 can be reduced, avoiding water leakage caused by assembly errors or loose connections. The second water outlet 225 connects with the first water outlet 224 to form a complete water outlet channel 223, which facilitates the forming of the water outlet channel 223 and reduces the complexity of processing. Since the second water outlet 225 is located inside the water box 2, and the interface between the first water outlet 224 and the second water outlet 225 is also located inside the water box 2, water leakage can be effectively prevented.
