Description

Technical Field

[0001] The utility model relates to the technical field of miniature refrigerators, in particular to a condenser back-embedded miniature refrigerator. Background Art

[0002] Microfridges are small refrigeration devices typically used to store small quantities of food and beverages. Their compact size makes them suitable for spaces with limited space, such as dormitories, offices, bedrooms, and cars. In addition to basic refrigeration, some models also feature a freezer compartment, providing greater flexibility to meet diverse storage needs. Furthermore, microfridges consume relatively little energy, making them an energy-efficient and environmentally friendly option. Their portability and versatility have made them a practical and popular household appliance in modern life.

[0003] However, due to the limited internal space of current micro refrigerators, it is difficult to install additional parts to optimize the installation and safety protection of the evaporator tube. This is because the design of the micro refrigerator needs to find a balance between maintaining a compact size and improving refrigeration efficiency. If additional assembly structures are added to install the evaporator tube, the size of the refrigerator will increase, losing its advantages of being small, portable and light. At the same time, the additional parts will also increase the installation cost of the equipment. Utility Model Content

[0004] (1) Technical problems solved: In response to the shortcomings of the existing technology, the present invention provides a condenser back-embedded micro refrigerator, which has the advantages of reducing additional parts and assembly steps while maintaining the compact size of the refrigerator, and does not require additional parts for safety protection of the evaporator tube after installation. It solves the problem that the traditional design leads to low utilization efficiency of the internal space of the refrigerator, requires additional parts and complex assembly steps, and requires additional protective measures to protect the evaporator tube, which increases the number of parts and assembly steps.

[0005] (2) Technical solution: In order to achieve the above-mentioned purpose of reducing additional parts and assembly steps while maintaining the compact size of the refrigerator and not requiring additional parts for safety protection of the evaporator after installation, the utility model provides the following technical solution: a condenser back-embedded micro refrigerator, comprising an outer shell and an inner shell, the inner shell being arranged in the outer shell, the bottom, front and rear sides of the outer shell being open, and the left and right sides of the inner shell being fixedly connected to the inner wall of the outer shell, the rear side of the outer shell being provided with a folded edge bent toward the inner side of the outer shell, the folded edge being in the shape of a groove, the rear side of the inner shell being fixedly connected to the folded edge, the rear edge of the inner shell being bent and inserted into the groove of the folded edge, an embedded assembly structure being formed between the rear side of the inner shell and the folded edge, and the evaporator tube being assembled in the embedded assembly structure.

[0006] Preferably, the inner shell is in a stepped shape, and the bottom surface of the inner shell is fixedly connected to the bottom surfaces on both sides of the outer shell.

[0007] Preferably, a fixing plate is further provided at the bottom of the shell, both ends of the fixing plate are fixedly connected to the left and right ends of the shell, a raised baffle is provided at the rear side of the fixing plate, and the fixing plate is positioned outside the evaporating tube.

[0008] Preferably, a support frame is fixedly arranged in the groove of the folded edge, the bottom of the support frame is fixedly connected to the bottom of the shell, and the rear side of the support frame is fixedly connected to the groove of the folded edge.

[0009] Preferably, the inner shell and the folded edge are fixedly connected by bolts.

[0010] Preferably, the length and height of the support frame are smaller than the bottom length and vertical height of the shell.

[0011] (III) Beneficial Effects: Compared with the prior art, the present invention provides a condenser back-embedded miniature refrigerator, which has the following beneficial effects:

[0012] 1. The condenser tube back-embedded micro refrigerator cooperates with the outer shell structure, the inner shell structure, and the folding edge structure. The embedded assembly structure between the folding edge and the inner shell can fix the evaporation tube in a specific position through the cooperation of the bent folding edge and the back side of the inner shell. The folding edge itself as a bent structure provides rigid support and is not easy to deform, thereby increasing the stability of the overall structure. The back edge of the inner shell is inserted into the groove of the folding edge to form a double fixation, making the evaporation tube more stable during the assembly process and not easy to move. At the same time, the embedded structure reduces the need for additional supporting structure through direct cooperation between the folding edge and the inner shell. The embedded structure provides higher mechanical strength in an integrated manner. The combination of the folding edge and the inner shell forms an integral support structure, which is not easy to separate or break, thereby improving the safety and durability of the equipment.

[0013] 2. The condenser back-embedded micro refrigerator uses a folding structure and an inner shell structure. The embedded design is fixed by physical embedding and snapping, and does not require additional bolts for multi-point fixation. This greatly reduces the number of bolts used, making the installation process simpler, eliminating many complicated steps, and improving installation efficiency. At the same time, reducing these parts and bolts means reducing the possibility of loosening or falling off, thereby improving the safety and stability of the equipment.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7The condenser-backed miniature refrigerator comprises an outer shell 1 and an inner shell 2. The inner shell 2 is mounted within the outer shell 1 and has openings at the bottom, front, and rear. This design creates a cavity between the inner shell 2 and the outer shell 1, facilitating installation of the cooling system and air circulation. The openings at the bottom, front, and rear facilitate heat dissipation and ventilation, while also facilitating maintenance and installation of internal components. The left and right sides of the inner shell 2 are fixedly connected to the inner walls of the outer shell 1. This secure connection ensures a stable position of the inner shell 2 within the outer shell 1, preventing it from shifting or shaking during use, which could affect the normal operation of the refrigerator. The inner shell 2 has a stepped shape, which increases internal space and facilitates storage. The stepped structure also allows for better circulation of cold air within the refrigerator, enhancing cooling efficiency. Furthermore, this shape enhances structural rigidity and stability. The bottom of the inner shell 2 is fixedly connected to the bottoms of both sides of the outer shell 1, further enhancing the structural stability of the entire refrigerator. By fixedly connecting the bottom surface of the inner shell 2 to the bottom surface of the outer shell 1, an integral rigid structure can be formed, which reduces vibration and noise while increasing the durability of the device. The rear side of the outer shell 1 is provided with a folded edge 3 bent toward the inner side of the outer shell 1. The folded edge 3 is in the shape of a groove. The bent folded edge 3 design provides an embedded mounting structure that can be used to fix the evaporation tube 4 and other components. The groove shape helps to increase the rigidity of the structure and prevent deformation. In addition, the groove shape of the folded edge 3 can provide additional support and fixed position to ensure that the installation of components such as the evaporation tube 4 is more stable and precise. The rear side of the inner shell 2 is fixedly connected to the folded edge 3, and the inner shell 2 and the folded edge 3 are fixedly connected by bolts. This fixing method ensures a firm connection between the inner shell 2 and the outer shell 1, increasing the structural stability of the entire refrigerator. The bolted connection ensures the connection strength between the rear side of the inner shell 2 and the folded edge 3, preventing the inner shell 2 from being displaced or loosened during use, thereby ensuring the long-term stability and durability of the device. The rear edge of the inner shell 2 is bent and inserted into the groove of the folded edge 3, and an embedded assembly structure is formed between the rear side of the inner shell 2 and the folded edge 3. This embedded assembly structure design forms a stable whole between the inner shell 2 and the outer shell 1, which increases the rigidity and stability of the structure. Through the bending of the edge of the inner shell 2 and the coordination of the groove, the displacement of the inner shell 2 can be effectively prevented, ensuring the accurate and stable position of internal components such as the evaporator tube 4. At the same time, this design also reduces the need for additional supporting structures and simplifies the manufacturing and installation process. The evaporator tube 4 is assembled in the embedded assembly structure. Assembling the evaporator tube 4 in the embedded structure can ensure that the fixed position of the evaporator tube 4 is clear and consistent, thereby increasing the accuracy and stability of the installation of the evaporator tube 4. The embedded structure provides a stable installation environment, allowing the evaporator tube 4 to effectively exchange heat, thereby improving the cooling effect of the refrigerator.

[0024] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , a fixing plate 5 is also provided at the bottom of the outer shell 1, and the two ends of the fixing plate 5 are fixedly connected to the left and right ends of the outer shell 1. The design of the fixing plate 5 further enhances the overall structural strength and stability of the refrigerator. By fixing the fixing plate 5 to the left and right ends of the outer shell 1, a more solid bottom support structure can be formed to prevent the device from deforming or tilting during use. The fixing plate 5 is provided with a raised baffle 6 on the rear side. The fixing plate 5 is located on the outside of the evaporator tube 4, and the fixing plate 5 can effectively protect the evaporator tube 4. The raised baffle 6 provides an additional physical barrier to prevent the evaporator tube 4 from being subjected to external impact or damage. The fixing plate 5 is located on the outside of the evaporator tube 4, which can provide support and protection to the evaporator tube 4 during installation and maintenance, ensuring the safety and stability of the evaporator tube 4. Please refer to Figure 4 、 Figure 6 and Figure 7 A support frame 7 is fixedly arranged in the groove of the folded edge 3. The support frame is fixedly arranged in the groove of the folded edge 3 mainly to increase the rigidity and stability of the overall structure. As an additional supporting component, the support frame 7 can effectively withstand the pressure from the inner and outer shells 1, prevent the folded edge 3 from being deformed or damaged, and thus enhance the mechanical strength of the entire refrigerator. The bottom of the support frame 7 is fixedly connected to the bottom of the outer shell 1, and the fixed connection between the bottom of the support frame and the bottom of the outer shell 1 further enhances the stability of the support frame 7. Through this fixed connection, the support frame 7 can better disperse the load on the bottom of the outer shell 1, prevent deformation or damage caused by excessive local pressure, and also ensure that the support frame 7 will not move or loosen during use. The rear side of the support frame 7 is fixedly connected to the groove of the folded edge 3. The fixed connection between the rear side of the support frame 7 and the groove of the folded edge 3 provides a double fixing effect, further enhancing the stability of the support frame 7. The groove of the folded edge 3 provides a stable installation position for the support frame 7, so that the support frame 7 can effectively support the outer shell 1. The length and height of the support frame 7 are smaller than the bottom edge length and vertical height of the outer shell 1. The size design of the support frame 7 is smaller than the bottom edge length and vertical height of the outer shell 1, which can ensure that the support frame 7 provides sufficient support and stability without affecting the utilization of the internal space of the refrigerator, which helps to save materials and reduce manufacturing costs. At the same time, it also ensures that the support frame 7 is more flexible and convenient during installation and maintenance inside the refrigerator.

[0025] Working Principle: By directly bending the rear side of the outer shell 1 inward to form a hem 3, and then securely connecting the hem 3 to the inner shell 2, a recessed assembly structure is formed between the hem 3 and the rear side of the inner shell 2. This recessed assembly structure uses the space between the hem 3 and the inner shell 2 to directly accommodate the evaporator tube 4, ensuring a clear and consistent fixed position and relatively stable and accurate installation of the evaporator tube 4. The recessed assembly structure between the hem 3 and the inner shell 2 secures the evaporator tube 4 in place by the fit of the bent hem 3 and the rear side of the inner shell 2. The hem 3 itself, as a bent structure, provides rigid support, resisting deformation and thus increasing the stability of the overall structure. Furthermore, the rear edge of the inner shell 2 fits into the groove of the hem 3, creating a double fixation, making the evaporator tube 4 more stable and less likely to move during assembly. Furthermore, the recessed assembly structure, through the direct fit of the hem 3 and the inner shell 2, reduces the need for additional support structures, and the integrated structure provides higher mechanical strength. The combination of the folded edge 3 and the inner shell 2 forms a single, integrated support structure that is resistant to separation or breakage, thereby enhancing the device's safety and durability. Furthermore, the embedded design secures the components through physical insertion and snap-fitting, eliminating the need for additional bolts for multi-point fastening. This significantly reduces the number of bolts used, simplifies the installation process, eliminates many complex steps, and improves installation efficiency. Furthermore, the reduction in these parts and bolts reduces the likelihood of loosening or falling off, thereby enhancing the device's safety and stability.
