Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerator and freezer technology, specifically a top-mounted refrigerator and freezer. Background Technology
[0002] Refrigerated and frozen display cases are widely used electrical appliances in homes, businesses, supermarkets, and restaurants for storing food, medicine, or other items requiring low-temperature preservation. Combining refrigeration and freezing functions, they can effectively store different types of items within varying temperature ranges, maintaining their freshness and quality. Refrigerated and frozen display cases are typically designed to provide a stable low-temperature environment, ensuring a constant internal temperature to meet diverse storage needs.
[0003] The existing technology has the following defects or problems: The existing technology disclosed in publication number CN216059987U is a top-mounted energy-saving and environmentally friendly commercial refrigerated display cabinet, which relates to the field of refrigerated display cabinet technology. It includes a cabinet body, a lifting mechanism, a fixing mechanism, and six shelves. There are two lifting mechanisms, which are symmetrically arranged on the side walls on both sides of the cabinet body. The fixing mechanism is arranged between the two lifting mechanisms and is connected to the inner wall of the cabinet body. The six shelves are arranged between the lifting mechanism and the fixing mechanism, and three shelves are arranged between one side of the lifting mechanism and the support frame, which makes the installation and operation of the shelves simple and convenient, and reduces the problem of ordinary display cabinets that cannot adjust the size of the displayed items.
[0004] During use, the above-mentioned equipment, through the cooperation between the lifting mechanism and the fixing mechanism, allows staff to adjust the shelves when they are full of items. They can pull the fixing mechanism to release the shelves from their fixed state, push the shelves to drive the lifting mechanism to move them up and down, and then push the fixing mechanism to move and adjust before fixing the shelves. This allows staff to adjust the shelves up and down even when they are full of items. The operation is simple and convenient, and the layout of the shelves can be flexibly adjusted.
[0005] The overall structure of the freezer and refrigerated display case described above allows for flexible adjustment of the internal shelf layout. During long-term use, the bottom heat dissipation area of the freezer may freeze due to moisture or accumulate dust, forming frost and other impurities. This will affect the heat dissipation effect and make it inconvenient to clean it regularly. At the same time, during transportation or use, the cabinet may tilt or become unstable due to vibration or external force, causing the freezer to tilt, resulting in uneven food storage or temperature fluctuations.
[0006] Therefore, a top-mounted refrigerator / freezer is proposed to solve the problems mentioned above. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a top-mounted refrigerator and freezer, which can solve the problems of inconvenience in regularly cleaning the heat dissipation area, and the cabinet may tilt or become unstable due to vibration or external forces during transportation or use.
[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a freezer body, with a heat dissipation box fixedly connected to the bottom of the freezer body. A motor is fixedly connected inside the heat dissipation box, and a connecting shaft is fixedly connected to the output end of the motor. A half-wheel is fixedly connected to the outer surface of the connecting shaft. Limiting rods are symmetrically fixedly connected inside the heat dissipation box, and an L-shaped slider is slidably connected to the outside of the limiting rods. An internal gear ring is fixedly connected to the other end of the L-shaped slider, and the internal gear ring meshes with the half-wheel. A connecting plate is fixedly connected to the outer surface of the heat sink, and a scraper is fixedly connected to the other end of the connecting plate. The scraper is slidably connected to the front interior of the heat sink. The motor inside the heat sink runs and drives the connecting shaft to rotate. The connecting shaft drives the half wheel fixed on the shaft to rotate synchronously. Since the half wheel meshes with the internal gear ring, and the internal gear ring is slidably connected to the limit rod through the L-shaped slider, the rotation of the half wheel will be converted into the internal gear ring sliding back and forth along the limit rod. The sliding of the internal gear ring drives the scraper to move back and forth synchronously through the connecting plate. The scraper slides inside the front of the heat sink.
[0009] Preferably, fixed blocks are fixedly connected to both sides of the outer surface of the freezer body, and a rotating shaft is rotatably connected inside the fixed blocks. A drive bevel gear is symmetrically fixedly connected to the outside of the rotating shaft, and the rotating shaft drives the drive bevel gears symmetrically fixed to it to rotate.
[0010] Preferably, support blocks are symmetrically fixedly connected to both sides of the outer surface of the freezer body. A limit ring is rotatably connected inside the support block. A threaded rod is fixedly connected through the inside of the limit ring. A driven bevel gear is fixedly connected to the top of the threaded rod. The driven bevel gear meshes with the driving bevel gear. Because the driving bevel gear meshes with the driven bevel gear at the top of the threaded rod, the rotation of the driving bevel gear will drive the driven bevel gear and the threaded rod fixed thereto to rotate synchronously.
[0011] Preferably, the outer surface of the threaded rod is threaded with a movable block, the lower surface of the movable block is fixedly connected with a hollow rod, and the bottom end of the hollow rod is fixedly connected with an adjusting plate. When the threaded rod rotates, the movable block threaded with it is limited by the inner wall of the support block and can only slide up and down along the support block. It will move up and down along the axial direction of the threaded rod, and the movable block drives the hollow rod and the adjusting plate fixed below to rise and fall synchronously.
[0012] Preferably, an electrical outlet is provided inside the top of the freezer body, and a cabinet door is provided on the front side of the electrical outlet. Several built-in shelves are provided inside the freezer body. After the freezer body is connected to the electrical outlet, the refrigeration system is started to provide a low-temperature storage environment inside. Opening the cabinet door allows items to be placed on the several built-in shelves inside.
[0013] Preferably, the outer surface of the movable block is slidably connected to the inner wall of the support block to stabilize the movement trajectory of the movable block.
[0014] Preferably, the outer surface of the hollow rod extends through the bottom of the support block, and the interior of the hollow rod is slidably connected to the outer surface of the threaded rod.
[0015] Compared with the prior art, the present invention provides a top-mounted refrigerator and freezer, which has the following advantages:
[0016] 1. By installing a motor inside the heat exchange box, the scraper slides outside the heat dissipation holes under the drive of the motor, which can effectively remove dust, grease, frost and other debris that may accumulate on the surface of the heat exchange box. By regularly scraping away these debris, the heat exchange box can dissipate heat to the external environment more efficiently, thereby improving the overall heat dissipation efficiency of the freezer.
[0017] 2. By installing an adjustment plate on the outside of the freezer body, and with the cooperation of bevel gears, the adjustment plate can be pressed against the ground according to the usage situation. This can effectively prevent the freezer from tilting or becoming unstable due to vibration or external force during transportation or use, and reduce uneven food storage or temperature fluctuations caused by the tilting of the freezer.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1 - Figure 5 This embodiment of a top-mounted refrigerator / freezer includes a refrigerator body 1. A heat dissipation box 2 is fixedly connected to the bottom of the refrigerator body 1. A motor 3 is fixedly connected to the inside of the heat dissipation box 2. A connecting shaft 4 is fixedly connected to the output end of the motor 3. A half-wheel 5 is fixedly connected to the outer surface of the connecting shaft 4. Limiting rods 6 are symmetrically fixedly connected inside the heat dissipation box 2. An L-shaped slider 7 is slidably connected to the outside of the limiting rod 6. An internal toothed ring 8 is fixedly connected to the other end of the L-shaped slider 7. The inside of the internal toothed ring 8 meshes with the half-wheel 5. A connecting plate 9 is fixedly connected to the outer surface of the internal toothed ring 8. A scraper 10 is fixedly connected to the other end of the connecting plate 9. The scraper 10 is slidably connected to the front interior of the heat dissipation box 2.
[0028] An electrical outlet 21 is installed inside the top of the freezer body 1, and a cabinet door 22 is installed on the front side of the electrical outlet 21. Several internal shelves 23 are installed inside the freezer body 1.
[0029] The motor 3 inside the heat sink 2 operates, driving the connecting shaft 4 to rotate. The connecting shaft 4 drives the half wheel 5 fixed on the shaft to rotate synchronously. Since the half wheel 5 meshes with the internal gear ring 8, and the internal gear ring 8 is slidably connected to the limit rod 6 through the L-shaped slider 7, the rotation of the half wheel 5 will be converted into the internal gear ring 8 sliding back and forth along the limit rod 6. The sliding of the internal gear ring 8 drives the scraper 10 to move back and forth synchronously through the connecting plate 9. When the scraper 10 slides inside the front side of the heat sink 2, it can automatically clean the dust accumulated in the heat dissipation area.
[0030] At this time, after the refrigerator body 1 is connected to the power cord 21, the refrigeration system is started to provide a low temperature storage environment inside. Opening the cabinet door 22 allows items to be placed on several built-in shelves 23 inside. After closing the cabinet door 22, the refrigerator body 1 maintains a low temperature inside.
[0031] Fixed blocks 11 are fixedly connected to both sides of the outer surface of the freezer body 1. Rotating shafts 12 are rotatably connected inside the fixed blocks 11. Driving bevel gears 13 are symmetrically fixedly connected to the outside of the rotating shafts 12. Support blocks 14 are symmetrically fixedly connected to both sides of the outer surface of the freezer body 1. Limiting rings 15 are rotatably connected inside the support blocks 14. Threaded rods 16 are fixedly connected through the inside of the limiting rings 15. Driven bevel gears 17 are fixedly connected to the top of the threaded rods 16. Driven bevel gears 17 mesh with driving bevel gears 13. Movable blocks 18 are threadedly connected to the outer surface of the threaded rods 16. Hollow rods 19 are fixedly connected to the lower surface of the movable blocks 18. Adjusting plates 20 are fixedly connected to the bottom end of the hollow rods 19.
[0032] The outer surface of the movable block 18 is slidably connected to the inner wall of the support block 14 to stabilize the movement trajectory of the movable block 18. The outer surface of the hollow rod 19 extends through the bottom of the support block 14, and the interior of the hollow rod 19 is slidably connected to the outer surface of the threaded rod 16.
[0033] The rotating shaft 12 inside the rotating fixed block 11 drives the externally symmetrically fixed active bevel gear 13 to rotate. Since the active bevel gear 13 meshes with the driven bevel gear 17 at the top of the threaded rod 16, the rotation of the active bevel gear 13 will drive the driven bevel gear 17 and the threaded rod 16 fixed thereto to rotate synchronously. When the threaded rod 16 rotates, the movable block 18 threadedly connected to it is limited by the inner wall of the support block 14 and will move up and down along the axial direction of the threaded rod 16. The movable block 18 drives the hollow rod 19 and the adjusting plate 20 fixed below to rise and fall synchronously.
[0034] The working principle of the above embodiment is as follows: When it is necessary to clean the ventilation opening of the heat sink 2, the motor 3 is started. The motor 3 inside the heat sink 2 runs and drives the connecting shaft 4 to rotate. The connecting shaft 4 drives the half wheel 5 fixed on the shaft to rotate synchronously. Since the half wheel 5 meshes with the internal gear ring 8, and the internal gear ring 8 is slidably connected to the limit rod 6 through the L-shaped slider 7, the rotation of the half wheel 5 will be converted into the internal gear ring 8 sliding back and forth along the limit rod 6. The sliding of the internal gear ring 8 drives the scraper 10 to move back and forth synchronously through the connecting plate 9. When the scraper 10 slides inside the front side of the heat sink 2, it can automatically clean the dust accumulated in the heat dissipation area and ensure heat dissipation efficiency.
[0035] To adjust the stability of the freezer body 1, simply rotate the shaft 12 inside the fixed block 11. The shaft 12 drives the externally symmetrically fixed active bevel gear 13 to rotate. Since the active bevel gear 13 meshes with the driven bevel gear 17 at the top of the threaded rod 16, the rotation of the active bevel gear 13 will drive the driven bevel gear 17 and the threaded rod 16 fixed thereto to rotate synchronously. The threaded rod 16 is limited within the support block 14 by the limiting ring 15, so that the threaded rod 16 can only rotate and cannot move. When the threaded rod 16 rotates, the movable block 18 connected to it by the thread is limited by the inner wall of the support block 14 and can only slide up and down along the support block 14. It will move up and down along the axial direction of the threaded rod 16. The movable block 18 drives the hollow rod 19 and the adjusting plate 20 fixed below to rise and fall synchronously. By adjusting the contact height between the adjusting plate 20 and the ground, the overall height of the freezer body 1 can be adjusted. The hollow rod 19 is sleeved on the outside of the threaded rod 16 and slides with the threaded rod 16 when the movable block 18 moves, ensuring structural stability.
[0036] After the refrigerator body 1 is connected to the power cord 21, the refrigeration system is activated to provide a low-temperature storage environment inside. Opening the cabinet door 22 allows items to be placed on several built-in shelves 23 inside. After closing the cabinet door 22, the refrigerator body 1 maintains the internal low temperature to achieve refrigeration or freezing storage of items.
[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
