[0027] The embodiment of the utility model will be explained in detail below in connection with the drawings.

[0028] As Figures 1 to 6As shown, the refrigerator self-evaporation device of the embodiment comprises a sub-condenser assembly 1 and a water pan 2, the top of the water pan 2 is provided with a top opening 21, the sub-condenser assembly 1 comprises a sub-condenser pipe 11 and a mounting member 12, the mounting member 12 can erect the sub-condenser pipe 11 above the water pan 2, by such design, the sub-condenser pipe 11 and the top opening 21 of the water pan 2 have a certain distance, which ensures that the sub-condenser pipe 11 will not directly contact with the water in the water pan 2, thereby avoiding the corrosion problem of the sub-condenser pipe 11 caused by direct contact with water, and even if the water pan 2 is full of water and overflows, the sub-condenser pipe 11 will not directly contact with the water, such design improves the protection ability of the sub-condenser, which can effectively prevent corrosion even in extreme cases, such isolation design greatly reduces the corrosion risk and improves the service life of the sub-condenser; and the sub-condenser pipe 11 is assembled through the mounting member 12, which separates the sub-condenser pipe 11 from the water pan 2, making it more convenient to disassemble and maintain the sub-condenser, the above design is not only suitable for coastal areas, but also suitable for other environments that may have corrosion risks.

[0029] As shown, Figures 1 to 6 The sub-condenser assembly 1 of the embodiment further comprises a plurality of heat exchange fins 13 installed on the sub-condenser pipe 11, the bottom of each heat exchange fin 13 extends into the water pan 2, the principle of such design is to use the water in the water pan 2 as an additional heat exchange medium, when the refrigerant flows in the sub-condenser pipe 11, its heat is transferred to the heat exchange fin 13 through the pipe wall, since the heat exchange fin 13 can contact with the water in the water pan 2, the heat can be further transferred to the water through the fin, thereby realizing heat exchange, by improving the heat exchange efficiency, the refrigerator can reach the set temperature faster and maintain the temperature more stably, thereby improving the overall performance of the refrigerator.

[0030] Specifically, since the heat exchange fin 13 can provide more surface area so that heat can be transferred from the sub-condenser pipe 11 to the surrounding environment, the addition of the heat exchange fin 13 significantly increases the heat exchange area of the sub-condenser assembly 1, making the heat exchange process more efficient.

[0031] Further, since the heat exchange fin 13 directly contacts with the water in the water pan 2, heat can be directly transferred to the water instead of only through the air, the water has large heat capacity and good heat conduction performance, so it can more effectively absorb heat and improve the overall heat exchange efficiency.

[0032] Further, although the bottom of the heat exchange fin 13 extends into the water pan 2, since the sub-condenser pipe 11 itself still maintains a certain distance from the water pan 2, the corrosion risk of the sub-condenser pipe 11 does not increase, at the same time, the fin design can use corrosion-resistant materials to further reduce the corrosion risk.

[0033] As Figures 1 to 6 shown, the water overflow member 22 is provided in the water pan 2, and the water inlet 221 is provided on the water overflow member 22, which is lower than the top opening 21 of the water pan 2. When the water level in the water pan 2 rises to a certain extent, the water will flow into the water overflow member 22 through the water inlet 221 lower than the top opening 21 of the water pan, and the water overflow member 22 is connected to the outside of the refrigerator or the drainage system, so that the water can be discharged through the water overflow member 22, thereby avoiding the situation that the water body overflows from the top opening 21 of the water pan 2 due to the high water level in the water pan 2.

[0034] By providing the water overflow member 22 and the water inlet 221, it can be ensured that when the water level in the water pan 2 reaches a predetermined height, the excess water can be effectively discharged, avoiding the water from overflowing from the top opening 21 of the water pan 2, thereby protecting other important components inside the refrigerator from water damage.

[0035] Further, water overflow may cause damage to electronic components, insulation materials, etc. of the refrigerator, and even may cause safety problems such as short circuit, and the design of the water overflow member 22 reduces such risks and improves the overall safety of the refrigerator.

[0036] As Figures 1 to 6 shown, the water overflow member 22 of the embodiment includes a water overflow pipe provided in the water pan 2, the water inlet 221 is provided at the top of the water overflow pipe, the bottom of the water overflow pipe is provided with a water outlet 222, and the bottom of the water overflow pipe can extend out of the bottom of the mounting bottom plate 3 through the avoidance hole 31.

[0037] Specifically, the design principle of the water overflow member 22 is to use gravity to discharge the excess water in the water pan 2 through the water overflow pipe. When the water level in the water pan 2 rises to a certain extent, the water will flow into the water overflow pipe through the water inlet 221 at the top of the water overflow pipe. Since the water overflow pipe is provided with a water outlet 222 at the bottom and extends to the outside of the water pan 2, the water can be discharged from the water pan through the water outlet 222, thereby keeping the water level in the water pan within a safe range.

[0038] Specifically, the design of the water overflow pipe ensures that the water in the water pan 2 can be discharged in time and effectively, avoiding the problem of overflow caused by high water level, and the design of the water outlet 222 at the bottom of the water overflow pipe can ensure that even in the case of high water level in the water pan 2, the function of the water overflow pipe will not be affected, improving the reliability of the entire drainage system.

[0039] Specifically, by extending the water overflow pipe to the outside of the water pan 2, not only the space inside the refrigerator is saved, but also the entire drainage system is more compact.

[0040] Further, the design of the overflow pipe can prevent water from polluting other components inside the refrigerator during the discharge process, and the design of the overflow pipe and its related components makes the installation and maintenance of the entire drainage system more simple and reduces the maintenance cost.

[0041] Further, the design of the overflow pipe can be more neatly integrated into the overall structure of the refrigerator, making the internal structure of the refrigerator more simple and compact.

[0042] As shown in Figures 1 to 6 The refrigerator self-evaporation device of the embodiment further comprises a mounting bottom plate 3, the auxiliary condenser assembly 1 and the water pan 2 are mounted on the mounting bottom plate 3, the mounting bottom plate 3 is provided with a relief hole 31, and the bottom of the overflow pipe can extend out of the bottom of the mounting bottom plate 3 through the relief hole 31.

[0043] Specifically, by providing the relief hole on the mounting bottom plate 3, the overflow pipe can smoothly pass through the mounting bottom plate while maintaining its function, without affecting the overall structure and performance of the refrigerator. The overflow pipe collects excess water from the water pan 2 and discharges the water outside the refrigerator.

[0044] Specifically, the mounting bottom plate 3 can provide a unified platform to integrate components such as the auxiliary condenser assembly 1 and the water pan 2 at one assembly location, facilitating installation and disassembly, and improving the maintainability of the entire refrigerator self-evaporation device.

[0045] Preferably, by providing the relief hole on the mounting bottom plate 3, the internal structure of the refrigerator above the mounting bottom plate 3 can be protected from the influence of the overflow pipe, avoiding potential damage caused by water discharge. For example, the mounting bottom plate 3 is also provided with important components of the refrigerator such as the compressor 4 and the main condenser 5. With such a design, water can be guided out of the refrigerator through the overflow assembly, preventing water from polluting other components inside the refrigerator during the discharge process.

[0046] Further, the design of the mounting bottom plate 3 and the relief hole makes the entire refrigerator self-evaporation device look more neat and beautiful, simplifies the structure of the drainage system, reduces unnecessary components, and makes the entire system more simple and efficient.

[0047] As shown in Figures 1 to 6 The mounting member 12 of the embodiment comprises two mounting end plates, and the two mounting end plates are respectively arranged on both sides of the water pan 2. Each mounting end plate is connected with the mounting bottom plate 3 through a first connecting piece, and the first connecting piece can realize detachable connection between the mounting end plate and the mounting bottom plate 3.

[0048] Specifically, the design principle of the mounting member 12 in this embodiment is to securely mount the secondary condenser pipe 11 on the mounting base plate 3 through mounting end plates and first connecting pieces. Each mounting end plate is located on the two sides of the water pan 2 and is connected to the mounting base plate 3 through a first connecting piece, which can ensure the secure and reliable connection between the secondary condenser pipe 11 and the mounting base plate 3. The design of the first connecting piece allows quick and repeatable assembly and disassembly between the mounting end plate and the mounting base plate 3 without the need for permanent fixing methods such as welding or gluing.

[0049] When the water pan 2 or the secondary condenser assembly 1 fails, the detachable connection allows the secondary condenser pipe 11 and related components to be quickly removed or replaced when maintenance or cleaning is required, reducing maintenance costs and time and improving repair efficiency.

[0050] The detachable connection allows the internal structure of the refrigerator to be adjusted or upgraded as necessary, increasing design flexibility.

[0051] The design of the mounting end plate and the first connecting piece simplifies the installation process, making the assembly of the entire refrigerator self-evaporation device faster and more convenient.

[0052] Further, by adjusting the size and position of the first connecting piece, different sizes and shapes of water pans can be accommodated, increasing the design versatility.

[0053] As shown in Figures 1 to 6 both sides of the water pan 2 of this embodiment are provided with second connecting pieces 24 that can be connected to the mounting base plate 3. The main function of the second connecting piece 24 is to achieve a stable connection between the water pan 2 and the mounting base plate 3. By providing second connecting pieces on both sides of the water pan 2, it can ensure that the water pan remains balanced and stable in the horizontal direction, and also facilitates assembly and disassembly.

[0054] Specifically, the second connecting pieces 24 on both sides ensure the stability of the water pan 2 on the mounting base plate 3, preventing displacement due to vibration during refrigerator operation. The design of the second connecting piece 24 helps to accurately position the water pan 2, ensuring its correct position on the mounting base plate 3, thereby improving the installation accuracy of the entire refrigerator self-evaporation device.

[0055] Further, when the water pan 2 needs to be maintained or replaced, the design of the second connecting piece 24 makes the disassembly process simpler and faster.

[0056] Further, by providing second connecting pieces 24 on both sides, the load on the water pan 2 can be distributed, reducing the pressure on a single connection point and improving the durability of the overall structure.

[0057] As shown in Figures 1 to 6As shown, the first connecting member of the embodiment includes connecting screws, each of the mounting end plates is provided with a first connecting hole 121 corresponding to the connecting screw, the mounting base plate 3 is provided with a second connecting hole 32 corresponding to the first connecting hole 121, the second connecting member 24 includes a connecting plate provided with a third connecting hole 241 corresponding to the first connecting hole 121, and the connecting screw can pass through the first connecting hole 121, the second connecting hole 32 and the third connecting hole 241 to mount the mounting end plate and the connecting plate on the mounting base plate 3. With such a design, the connecting plate on the water pan 2 and the mounting end plate on the auxiliary condenser pipe 11 can be fixed together on the mounting base plate 3 by the connecting screw, effectively reducing the number of parts of the connecting structure, and making the structure of the refrigerator self-evaporation device more compact.

[0058] Specifically, the design principle is to reduce unnecessary parts through integrated connection, use connecting screws as the main fixing means, and realize stable installation of the water pan and the auxiliary condenser pipe through cooperation of multiple connecting holes. The connecting screw passes through the first connecting hole 121 of the mounting end plate, the second connecting hole 32 of the mounting base plate, and the third connecting hole 241 of the connecting plate, thereby tightly connecting each part together.

[0059] Specifically, by reducing the number of parts of the connecting structure, the design of the entire refrigerator self-evaporation device is simplified, and the manufacturing cost is reduced.

[0060] Specifically, the integrated connection design makes the structure of the entire refrigerator self-evaporation device more compact, saves space, and also makes the device more beautiful.

[0061] Further, using connecting screws for fixation can quickly complete installation, improve installation efficiency, and reduce installation time. When maintenance or replacement of parts is required, the connecting screws can be quickly disassembled and reinstalled, reducing maintenance difficulty and time. The fixing method of the connecting screws provides higher structural stability, ensuring the stability of the water pan and the auxiliary condenser pipe during operation of the refrigerator.

[0062] Further, through precise hole design and tightening of the connecting screws, the reliability of the connecting structure is improved, and failures caused by connection problems are reduced.

[0063] Further, due to the standardization of the connecting screws, the need for special tools may be reduced, making installation and disassembly work simpler.

[0064] In other embodiments, the connecting plate is fixed to the mounting base plate 3 by another connecting screw, and does not share the same second connecting hole 32 with the mounting end plate. The appropriate design can be selected according to actual needs.

[0065] In other embodiments, the connecting plate on the water receiving tray 2 and the mounting end plate on the auxiliary condenser pipe 11 can also be fixed to the mounting base plate 3 by means of snap-fit ​​connection or slide rail connection, and a suitable design can be selected according to actual needs.

[0066] like Figures 1 to 6 As shown, a refrigerator according to this embodiment includes a compressor 4, a main condenser 5, and a refrigerator self-evaporation device as described in any of the above. The compressor 4, the main condenser 5, and the auxiliary condenser assembly 1 are arranged adjacent to each other, and the water receiving tray 2 is located below the auxiliary condenser assembly 1.

[0067] Specifically, the freezer in this embodiment adopts the above-mentioned freezer self-evaporation device design, that is, the distance design between the auxiliary condenser 11 and the water tray 2 effectively avoids the auxiliary condenser 11 from directly contacting the water in the water tray 2. Even if the water tray is full and overflows, the auxiliary condenser 11 will not directly contact the water, thereby reducing the corrosion problem of the auxiliary condenser 11 caused by water and improving the protection capability of the auxiliary condenser, especially in extreme environments. By reducing the risk of corrosion, the service life of the auxiliary condenser is significantly improved.

[0068] Furthermore, the auxiliary condenser tube 11 is assembled through the mounting component 12 and is designed separately from the water tray 2, making it more convenient to disassemble and maintain the auxiliary condenser. When the auxiliary condenser tube needs to be replaced, it can be quickly separated from the water tray, reducing maintenance time.

[0069] This design is suitable for a variety of environments, especially coastal areas and other environments where corrosion risks may exist.

[0070] Furthermore, by incorporating an overflow component, the water level in the drip tray can be ensured to remain within the tray, preventing water from overflowing from the top opening. The inlet design helps control the water level in the drip tray, ensuring that excess water can be effectively drained. Moreover, by preventing water overflow, other important components inside the freezer are protected from water damage, thus improving the overall system reliability. Through the above design, the reliability of the entire refrigeration system is improved, reducing malfunctions caused by improper maintenance or environmental factors.

[0071] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
