Technical Field
[0001] This utility model belongs to the field of auxiliary heat dissipation technology for embedded refrigerators, and relates to the heat dissipation structure of embedded refrigerators. Background Technology
[0002] With the popularization of the concept of integrated home furnishing, built-in refrigerators are gradually becoming the mainstream choice for family kitchens because they can achieve seamless integration with cabinets, reduce space waste, and improve overall aesthetics. The core advantage of built-in refrigerators lies in the fact that through precise size design and installation structure, the gap between the sides and top of the refrigerator and the cabinets is reduced to less than 1cm, or even completely embedded in the cabinet space, breaking the "separation" between traditional refrigerators and cabinets.
[0003] However, while the built-in design brings aesthetic and space advantages, it also poses a severe challenge to heat dissipation performance. Traditional refrigerators mostly adopt side, rear, or bottom open heat dissipation structures: side heat dissipation requires a 10-15cm heat dissipation gap on both sides of the refrigerator, which conflicts with the "seamless" requirement of built-in; rear heat dissipation relies on the air circulation between the back of the refrigerator and the wall, and when built-in is installed, the back is close to the cabinet, and the air can hardly flow; although bottom heat dissipation does not require a side gap, the traditional bottom heat dissipation holes are easily blocked by the bottom of the cabinet after being embedded, resulting in insufficient intake of cold air and obstruction of hot air exhaust, forming a "heat dissipation island".
[0004] The current heat dissipation solutions for built-in refrigerators have obvious defects: some products simply compress the size of the heat dissipation channel to adapt to built-in design, resulting in a sharp drop in heat dissipation efficiency. When the refrigerator is running, the heat generated by components such as the compressor and condenser cannot be dissipated in time, the internal temperature is prone to fluctuation, and the compressor needs to be started and stopped frequently to maintain the set temperature. This not only increases energy consumption, but also accelerates the aging of core components such as the compressor and thermostat. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0024] Example 1 like Figure 1 - Figure 6 As shown, the heat dissipation structure of the zero-embedded refrigerator includes a main heat dissipation box 101. A support frame 102 is installed at the upper end of the main heat dissipation box 101. A connecting pipe 103 is fixedly connected to the end of the main heat dissipation box 101. An exhaust box 104 is installed at the end of the connecting pipe 103 away from the main heat dissipation box 101. An installation groove 105 is opened on the inner side of the upper end of the support frame 102. A crisscrossing reinforcing rib 106 is fixedly connected to the inner side of the support frame 102. Multiple sets of reinforcing ribs 106 form a uniform grid structure. A refrigerator body 107 is installed at the upper end of the support frame 102. A moving component is provided between the main heat dissipation box 101 and the support frame 102. A driving component is provided on the inner side of the support frame 102. An exhaust component is provided on the inner side of the exhaust box 104. First, the main heat dissipation box 101 and the connecting pipe 103 are installed on the inner side of the room floor, while the track 202 is placed on the upper part of the floor to facilitate the subsequent sliding of the rotating support wheel 201 from the inner side of the track 202 without being blocked by the ground. Then, the exhaust box 104 is installed on the outer side of the room, so that the exhaust box 104, the connecting pipe 103, and the main heat dissipation box 101 are interconnected. Then, the refrigerator body 107 is placed on the inner side of the mounting slot 105, and the load-bearing capacity of the supporting frame 102 is enhanced by the reinforcing rib 106. When the refrigerator body 107 exhausts heat from the bottom, the heat is transferred to the inner side of the main heat dissipation box 101 through the supporting frame 102. Then, the heat inside the main heat dissipation box 101 is exhausted to the outer side of the room through the connecting pipe 103 and the exhaust box 104.
[0025] Multiple sets of support ribs 501 are fixedly connected to the inner side of the connecting pipe 103. The support ribs 501 are made of high-strength alloy steel. By installing multiple sets of support ribs 501 made of high-strength alloy steel on the inner side of the connecting pipe 103, the structural support points are distributed to increase the load-bearing capacity and deformation resistance of the connecting pipe 103, thus ensuring the stability of the connecting pipe 103 in long-term use.
[0026] Multiple sets of exhaust fans 601 are installed inside the exhaust box 104; Multiple exhaust fans 601 are installed inside the exhaust box 104. After starting, they can accelerate the airflow speed inside the exhaust box 104, connecting pipe 103, supporting frame 102, and heat dissipation main box 101, quickly expelling heat to the outside and improving heat dissipation efficiency.
[0027] A sealing plate 701 is fixedly connected between the exhaust box 104 and the exhaust fan 601; The gap between the exhaust fan 601 and the exhaust box 104 is sealed by the sealing plate 701.
[0028] Multiple sets of mounting plates 801 are fixedly connected to the outer side of the exhaust box 104; The mounting plate 801 makes it easy for the installer to install the exhaust box 104 on the surface of the outer wall of the room.
[0029] A temperature sensor 901 is installed inside the main heat dissipation box 101, and a controller 902 is installed inside the exhaust box 104. The temperature sensor 901 monitors the temperature inside the heat dissipation main housing 101 in real time. When the temperature inside the heat dissipation main housing 101 reaches the preset value, the information is fed back to the controller 902. After receiving the signal, the controller 902 starts the exhaust fan 601 to extract the hot air from inside the heat dissipation main housing 101.
[0030] Both the heat dissipation main housing 101 and the load-bearing frame 102 are made of high-strength alloy steel. Enhance the load-bearing capacity of the heat dissipation main housing 101 and the load-bearing frame 102.
[0031] When the refrigerator body 107 is in operation and generates heat, the heat is discharged from the bottom of the refrigerator body 107 to the inside of the support frame 102, and then enters the inside of the heat dissipation main box 101 through the support frame 102. Temperature sensor 901 monitors the temperature inside the heat dissipation main housing 101 in real time. When the temperature reaches the preset value, controller 902 receives the information feedback and starts exhaust fan 601. After the exhaust fan 601 is turned on, the heat inside the main heat dissipation box 101 is discharged to the outside through the connecting pipe 103 and the exhaust box 104 in sequence, completing the heat dissipation process.
[0032] The entire system ensures structural stability through high-strength materials and achieves efficient heat dissipation through intelligent control. It is suitable for zero-embedded installation scenarios, allowing the heat generated by the refrigerator to be smoothly discharged outdoors along the path composed of the main heat dissipation box 101, connecting pipe 103, and exhaust box 104. This avoids heat dissipation problems caused by poor air circulation in the embedded space, thereby reducing wear and tear on refrigerator components caused by poor heat dissipation, effectively extending the service life of the embedded refrigerator, and ensuring stable and efficient operation of the refrigerator while reducing unnecessary energy consumption.
[0033] Example 2 like Figure 2 - Figure 4 As shown, the moving component includes a rotating support wheel 201 and a track 202. Multiple sets of rotating support wheels 201 are symmetrically rotatably connected to the inner side of the lower end of the bearing frame 102. Tracks 202 are symmetrically opened on the inner side of the upper end of the heat dissipation main box 101, and the rotating support wheels 201 are located inside the track 202.
[0034] The moving component also includes a limiting moving plate 301, a limiting rod 302, and a lead screw 303. The lower end of the bearing frame 102 is fixedly connected to the limiting moving plate 301. Multiple sets of limiting rods 302 are fixedly connected to the inner side of the heat dissipation main box 101. The limiting moving plate 301 is sleeved on the outer side of the limiting rod 302 and slidably connected to the limiting rod 302. The lead screw 303 is rotatably connected to the inner side of the heat dissipation main box 101. The lead screw 303 is located inside the limiting moving plate 301 and is threadedly connected to the limiting moving plate 301.
[0035] The drive assembly includes a servo motor 401, a drive gear 402, and a driven gear 403. The servo motor 401 is fixedly connected to the inner side of the lower end of the heat dissipation main housing 101. The drive gear 402 is fixedly connected to the output end of the servo motor 401. The driven gear 403 is fixedly connected to the outer side of the lead screw 303. The driven gear 403 meshes with the drive gear 402.
[0036] When working, the servo motor 401 is started, and its output end drives the drive gear 402 to rotate. Since the drive gear 402 and the driven gear 403 mesh with each other, the power is transmitted to the driven gear 403, which in turn drives the lead screw 303 to rotate synchronously. At this time, since the lead screw 303 and the limit moving plate 301 are connected by threads, and the rotating support wheel 201 provides stable rotational support for the bearing frame 102, the rotation of the lead screw 303 will be converted into the linear displacement of the bearing frame 102, thereby smoothly moving the bearing frame 102 to the outside of the narrow space. In this way, installers can carry out the installation work on the refrigerator body 107 in a more spacious operating space. This not only makes it easier to adjust the position of the refrigerator body 107 and connect related pipelines, but also reduces installation deviations or component collisions caused by limited space. After the refrigerator body 107 is installed in place, the above steps are reversed: control the servo motor 401 to reverse, so that the drive gear 402, driven gear 403 and lead screw 303 move in reverse in sequence, and drive the bearing frame 102 together with the installed refrigerator body 107 to reset through the thread transmission, and finally accurately embed the refrigerator body 107 into the narrow space to complete the embedded installation. The entire process utilizes a mechanical transmission structure to enable the flexible entry and exit of the load-bearing frame 102, which solves the problem of inconvenient installation and operation in narrow spaces, and ensures the precision and stability of the embedded installation of the refrigerator body 107.

Clearly, many modifications and variations can be made based on the content of this specification.
