Description

Technical Field

[0001] This utility model relates to the field of food storage cabinet technology, and in particular to a uniform direct cooling food storage cabinet. Background Technology

[0002] In the use of existing direct-cooling refrigerators, uniform cooling and condensate management have always been key issues affecting preservation performance and user experience. Current top-mounted evaporators cool by allowing airflow to descend, a slow and ineffective process. Some refrigerators lack dedicated water collection mechanisms or have poorly designed water collection structures, allowing condensate to drip directly onto displayed items, causing them to become damp and damaged. Furthermore, some refrigerators have water accumulation in their water collection components, preventing rapid drainage and leading to bacterial growth over time. This not only affects the hygiene inside the refrigerator but may also damage refrigerator components due to leakage.

[0003] Therefore, this application provides a uniform direct-cooling refrigerator to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a uniform direct-cooling refrigerator, which aims to solve the problem that the existing top evaporator cooling relies on the autonomous downward flow of air to achieve cooling, which is slow and ineffective.

[0005] To achieve the above objectives, this application provides the following technical solution: a uniform direct cooling preservation cabinet, including a unit cabinet and a cabinet body, and an evaporator. The top surface of the unit cabinet is provided with the cabinet body, and the cabinet body is provided inside the cabinet body.

[0006] Its features include: a circulating refrigeration mechanism is provided between the evaporator and the cabinet; a protective cover is provided below the evaporator; a water receiving mechanism is provided below the protective cover; and a lighting lamp is provided on the bottom surface of the water receiving mechanism.

[0007] The circulating refrigeration mechanism also includes a refrigeration fan, a top cover, and a distribution cover. The top surface of the cabinet has a hole, and the top cover is installed inside the hole. The top cover is a cover, and a distribution cover is installed on the inner wall of the top cover. The length of the distribution cover is shorter than that of the top cover.

[0008] The evaporator is mounted on the cabinet via fasteners No. 1 and No. 2 on the left and right sides. Fastener No. 1 has a hole in which a cooling fan is installed. The cooling fan is located below the top cover.

[0009] The distributor cover is equipped with multiple distribution holes.

[0010] Preferably, the protective cover has a U-shaped cross-section and a groove on its inner bottom surface, so that the protective cover covers the evaporator from below;

[0011] A drain port is provided on the inner wall of the groove.

[0012] Preferably, the bottom of the protective cover is inclined, and heat insulation cotton is provided in the groove, with the top surface of the heat insulation cotton being level with the bottom surface of the drain port.

[0013] Most components are connected by bolts, making installation and disassembly convenient and facilitating later maintenance and repair. The insulation cotton on the protective cover not only helps guide condensate but also reduces cold air loss. The light at the bottom of the water collection box provides illumination for the cabinet interior while collecting water, serving multiple purposes and enhancing the practicality of the refrigerator. In addition, details such as the diversion cover and drainage port are designed according to the laws of gas and liquid flow, ensuring efficient and stable operation of each mechanism.

[0014] The protective cover beneath the evaporator protects it from impacts by foreign objects, while also reducing the direct adhesion of dust and other impurities to the evaporator surface, ensuring its normal operating efficiency. The protective cover is secured to the fasteners with bolts, resulting in a robust structure that further enhances the protection of the evaporator and extends the lifespan of both the evaporator and the entire refrigerator.

[0015] Preferably, the water receiving mechanism includes a water receiving box and a drain pipe. The water receiving box is located below the protective cover, and the cross-sectional shape of the water receiving box is U-shaped. The two top surfaces of the water receiving box are respectively connected to the first fixing component and the second fixing component.

[0016] An air inlet is provided on the bottom of the water receiving box, and a hole is provided on the inner wall of the water receiving box, through which a drain pipe connecting to the outside is installed.

[0017] Preferably, the bottom surface of the water receiving box is inclined.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] This invention utilizes a circulating refrigeration mechanism. Gas blown by the refrigeration fan is guided through an air duct formed by the top cover and the distribution cover, then evenly blown downwards through the distribution holes of the distribution cover. After heat exchange in the evaporator, the resulting cold air is discharged through the protective cover's mesh and then flows downwards along the curved surface of the cabinet door. This gas flow path design allows the cold air to gradually diffuse to all areas of the cabinet, effectively solving the problem of uneven cold air distribution in traditional refrigeration cabinets. This ensures a gradually constant internal temperature, significantly improving the preservation effect of the displayed items.

[0020] This invention employs a multi-stage water collection mechanism to ensure effective condensate treatment. Condensate from the evaporator first drips onto a lower protective cover. The bottom surface of the cover is inclined and insulated, allowing the condensate to slide down the inclined surface through a drain into a collection box. The collection box is also inclined, guiding the condensate quickly to the drain pipe for external discharge. This entire process prevents condensate from dripping onto the displayed items and solves the problem of condensate accumulation inside the protective cover and collection box, ensuring cabinet hygiene and reducing the risk of component damage due to water accumulation.

[0029] 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.

[0030] Example: Reference Figure 1-6 The illustrated uniform direct-cooling refrigerator includes a unit cabinet 1 and a cabinet body 2. The top of the cabinet body 2 has an internally and externally communicating hole. An evaporator 8 is located below the hole. The evaporator 8 is mounted on the cabinet body 2 via a first fixing member 5 and a second fixing member 6 located on the left and right sides. A suitable circulating refrigeration mechanism is installed within the aforementioned hole. To protect the evaporator 8, a protective cover 9 is provided below it. The protective cover 9 protects the evaporator 8 from bottom to top, and the top of the protective cover 9 is fixed to the first fixing member 5 and the second fixing member 6 by bolts. To prevent condensate generated by the evaporator 8 during use from dripping onto the displayed items, a water-collecting mechanism is provided below the evaporator 8.

[0031] As one embodiment of this invention, the circulating refrigeration mechanism has an interconnected hole on the first fixing component 5. A refrigeration fan 7, which drives the airflow inside the cabinet 2, is installed in the hole. The top cover 3 is located in the hole and is a cover. A diversion cover 4 is provided on the inner wall of the top cover 3 (the combination of the diversion cover 4 and the top cover 3 is as follows). Figure 5 As shown), the length of the diversion cover 4 is less than the length of the top cover 3, thus providing an inlet for the gas blown out by the refrigeration fan 7 to enter between the top cover 3 and the diversion cover 4;

[0032] Diversion holes 400 are arrayed on the diversion cover 4. After the gas enters the air duct, it is blown downward through the diversion holes 400. During this process, the gas passes through the evaporator 8 and undergoes heat exchange, so that the gas becomes cold air and is discharged from the grid of the protective cover 9. The gas flows from top to bottom along the curved surface of the cabinet door of the cabinet 2, so that the temperature inside the cabinet 2 gradually becomes constant.

[0033] As one embodiment of this invention, the water receiving mechanism is as follows: a set of water receiving boxes 11 are provided below the protective cover 9. The specifications of the water receiving boxes 11 are larger than those of the protective cover 9. The water receiving boxes 11 are fixed by bolts connected to the first fixing member 5 and the second fixing member 6. A hole communicating with the outside is provided on the inner wall of the water receiving box 11. A drain pipe 12 is provided in the hole. The drain pipe 12 communicates with the outside and draws out the water that falls into the water receiving box 11.

[0034] As one implementation method in this embodiment, in order to avoid condensation accumulating inside the protective cover 9, insulation cotton 10 is provided on the protective cover 9. Since the inner bottom surface of the protective cover 9 is inclined, after the condensation falls onto the insulation cotton 10, it slides down the inclined surface to the drain port 900. Then the condensation falls through the drain port 900 onto the water collection box 11. Since the water collection box 11 is also inclined, after the condensation falls onto the water collection box 11, it quickly flows to the drain pipe 12 for external discharge.

[0035] As one embodiment of this invention, a light 13 for illuminating the cabinet 2 is provided on the bottom surface of the water receiving box 11.

[0036] The working principle of this utility model is as follows: By starting the cooling fan 7 inside the cabinet 2, the cooling fan 7 starts working, driving the air flow inside the cabinet 2. Then, driven by the cooling fan 7, the air enters the top cover 3. After contacting the inner wall of the top cover 3, the air enters the air duct formed by the top cover 3 and the diversion cover 4. Then, the air is blown out through the diversion hole 400 provided on the diversion cover 4. The blown air passes through the evaporator 8 (the evaporator 8 is installed and fixed by the first fixing part 5 and the second fixing part 6 on the left and right sides), so that the air is cooled. Then, the air is blown out through the mesh holes on the protective cover 9. Then, along the cabinet door of the cabinet 2, under the action of the inclined surface of the cabinet door, the cold air moves to the bottom of the cabinet 2, and uniformly cools the entire interior of the cabinet 2. During this process, the circuit components inside the unit cabinet 1 work synchronously.

[0037] During prolonged use and when the cabinet door is opened and closed, condensation will form on the evaporator 8 due to the temperature difference between the inside and outside of the cabinet. To prevent the condensation from dripping directly onto the displayed items, a protective cover 9 is installed below the evaporator 8. To prevent condensation from accumulating on the protective cover 9, insulation cotton 10 is installed on the inner bottom surface of the protective cover 9. After the condensation drips onto the insulation cotton 10, it slides along the top surface of the insulation cotton (because the bottom of the protective cover 9 is inclined, the insulation cotton is also inclined). After sliding to the drain port 900, the condensation drips onto the water collection box 11. Due to the inclined design of the water collection box 11, the condensation flows to the drain pipe 12 for external discharge. The lighting 13 at the bottom of the water collection box 11 provides lighting for the inside of the cabinet.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
