Technical Field
[0001] This utility model relates to the field of freezer technology, and in particular to a freezer with an external condenser. Background Technology
[0002] In existing technologies, the condenser of a freezer is mostly built into the cabinet's inner layer or at the back, resulting in problems such as low heat dissipation efficiency, occupying internal space, and operating noise affecting the user experience. To solve these problems, a design has emerged that mounts the condenser externally to the freezer cabinet. However, existing external condensers are usually directly fixed to the back of the cabinet with multiple screws, and their refrigerant piping connections use a traditional nut-locking method, requiring manual valve operation. This installation method has the following significant drawbacks: installation is cumbersome and must be performed by professional technicians; ordinary users cannot install or disassemble it themselves; threaded connections are prone to refrigerant leakage due to wear or aging of the seals after repeated disassembly and reassembly.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a freezer with an external condenser, including a freezer body 1 and an external condenser module 2. An L-shaped mounting base plate 3 is provided on the back of the freezer body 1. A first connecting connector 4 is provided on the mounting base plate 3, and a second connecting connector 5, which mates with the first connecting connector 4, is provided on the shell of the external condenser module 2. A quick-connect guide mechanism 6 is provided between the mounting base plate 3 and the shell of the external condenser module 2 to guide the horizontal movement of the external condenser module 2 and to align and insert the first connecting connector 4 and the second connecting connector 5. The first connecting connector 4 and the second connecting connector 5 are provided as one or more sets, and a quick-connect self-sealing valve assembly 7 is provided that automatically opens when the external condenser module 2 moves along the quick-connect guide mechanism 6 to the working position and automatically seals when separated. Through the cooperation of the quick-connect guide mechanism 6 and the quick-connect self-sealing valve assembly 7, the external condenser module 2 can be quickly installed and disassembled without tools, avoiding the risk of refrigerant leakage and greatly improving the ease of use and reliability of the freezer with the external condenser.
[0019] The quick-connect self-sealing valve assembly 7 includes a limiting ring 8 and a spherical slot 9 disposed inside the first connecting joint 4 and the second connecting joint 5. A valve core 10 matching the spherical slot 9 is disposed between the limiting ring 8 and the spherical slot 9. A return spring 11 is disposed between the limiting ring 8 and the valve core 10. A push rod 12 is disposed at the end of the valve core 10 away from the return spring 11. The outer diameter of the push rod 12 is smaller than the diameter of the spherical slot 9. The port of the first connecting joint 4 is provided with a tapered outer tube 13, and the port of the second connecting joint 5 is provided with a tapered outer tube 13 matching the tapered outer tube 13. A sealing gasket 15 is provided at the connection between the inner tube 14, the tapered outer tube 13 and the tapered inner tube 14. The valve core 10 is normally closed under the preload of the return spring 11, sealing the flow channel. When the external condenser module 2 moves to the working position, the tapered inner tube 14 and the tapered outer tube 13 are matched and inserted. At the same time, the push rod 12 in the second connecting joint 5 and the push rod 12 in the first connecting joint 4 come into contact, so that the two valve cores 10 are separated from the two spherical slots 9 at the same time. The return spring 11 is compressed, opening the flow channel, and the sealing gasket 15 plays a good sealing role.
[0020] The quick-installation guide mechanism 6 includes at least one guide rail 16 set on the mounting base plate 3 and a guide slider 17 set on the housing of the external condenser module 2 that matches the guide rail 16. Through the cooperation of the guide rail 16 and the guide slider 17, the installation process is simplified into a single linear motion, ensuring the smoothness and efficiency of the connection process.
[0021] Both the first connecting joint 4 and the second connecting joint 5 include a refrigerant pipeline quick connector and an electrical connector. The insertion and disconnection of the electrical connector are synchronized with the conduction and sealing of the refrigerant pipeline quick connector. Users only need one action to complete the reliable connection of the two media, simplifying the operation process.
[0022] The end of the guide slide rail 16 is fitted with a spring pin 18, and the guide slider 17 is provided with a locking hole 19 that matches the pin of the spring pin 18. The end of the pin of the spring pin 18 is inclined, and the guide slider 17 is provided with an inclined groove that matches the inclined part of the pin of the spring pin 18. After the guide slider 17 on the housing of the external condenser module 2 moves to the middle end, the inclined groove on the guide slider 17 abuts against the inclined part of the pin of the spring pin 18, which compresses the spring of the spring pin 18 and retracts the pin. After the pin of the spring pin 18 corresponds to the locking hole 19, the pin of the spring pin 18 extends under the action of the spring force and matches the locking hole 19 for insertion. This can lock the external condenser module 2 in the working position, prevent accidental slippage, and improve safety and stability.
[0023] During operation, the cooperation between the guide rail 16 and the guide slider 17 simplifies the installation process into a single linear motion, ensuring the smoothness and efficiency of the connection process. When the guide slider 17 moves to the end of the guide rail 16, the inclined groove on the guide slider 17 abuts against the inclined part of the spring pin 18, causing the spring of the spring pin 18 to compress and the pin to retract. After the pin of the spring pin 18 aligns with the locking hole 19, the pin of the spring pin 18 extends under the action of the spring force and matches the locking hole 19 for insertion, allowing the external condenser module to be connected. 2. Locked in the working position to prevent accidental slippage, improving safety and stability. At the same time, the valve core 10 is in a normally closed state under the preload of the return spring 11, sealing the flow channel. When the external condenser module 2 moves to the working position, the conical inner tube 14 matches and inserts with the conical outer tube 13. At the same time, after the push rod 12 in the second connecting joint 5 and the push rod 12 in the first connecting joint 4 come into contact, the two valve cores 10 are separated from the two spherical slots 9 at the same time. The return spring 11 is compressed, opening the flow channel, and the sealing gasket 15 provides a good sealing effect.
