Description

Technical Field

[0001] The utility model relates to the technical field of transport containers, and more specifically, it relates to a refrigerated box. Background Art

[0002] There is a saying of "the last mile" in cold chain logistics, which refers to the last section of the journey for products that need to be refrigerated during transportation to reach consumers. In this process, there are problems such as insufficient cold storage and insulation capabilities and difficult transportation. Electric tricycles can be used to replace cars for refrigerated transportation in specific environments. Such a change poses severe tests to the refrigeration function, internal layout, usage efficiency, and lifespan of the refrigerated box. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a refrigerated box to solve one or more of the above problems.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A refrigerated box includes a box body. The front end of the box body is a freezer compartment, the rear end of the box body is a refrigerating compartment. An evaporator is provided in the freezer compartment. Circulation air holes are opened on the heat-insulating wall in the refrigerating compartment. The cabinet doors of the freezer compartment and the refrigerating compartment are both magnetic doors.

[0006] Further, the length, width, and height of the box body are all adjusted according to the adapted electric tricycle, and mounting parts for docking with the electric tricycle are provided at the four corners, bottom, and sides of the box body.

[0007] Further, the space of the freezer compartment is larger than that of the refrigerating compartment, and a compressor is externally arranged at the front end of the box body.

[0008] Further, at least two circulation air holes are opened and communicated. The upper end of the upper circulation air hole is set to align with the height of the upper hinge of the cabinet door, and the lower end of the lower circulation air hole is set to align with the bottom surface height of the cabinet door.

[0009] Further, the magnetic door includes a set of magnetic fixing seats and magnetic handles. The end face of the contact end of the magnetic fixing seat and the sealing strip of the magnetic handle both carry magnetic parts, and the sealing strip isolates the gap between the cabinet door and the box body.

[0010] Further, the cross-section of the cabinet door is a convex-shaped structure. Step-shaped grooves are opened on both sides of the door groove of the box body. A buffer member is provided at the corner position corresponding to the door groove after the cabinet door is closed, and the buffer member does not contact the box body.

[0011] In summary, the utility model has the following beneficial effects: Through the structural design of pre-freezing and post-refrigeration, the installation positions of the evaporator and the compressor are reasonably arranged, which is convenient for riding an electric tricycle; By setting circulation air holes, the rapid refrigeration function is realized, and the economy is better; Through the magnetic attraction design of the door opening, not only the basic sealing effect is ensured, but also compared with the sealing of the rubber strip interference fit, the problem of sealing failure caused by rubber strip aging and cross-section deformation is avoided, and the overall service life is longer and the use efficiency is higher.

[0018] The following further describes the present utility model in detail with reference to the attached Figures 1-5 drawings.

[0019] A refrigerated box is suitable for docking with small transportation tools such as electric tricycles. Compared with conventional motor transport refrigerated containers, it is smaller in volume and has complete functions, and is suitable for scenarios where cars are difficult to pass or for short-distance transportation. The refrigerated box is a standard cabinet-type box body 1, and the size can be customized and adapted according to the size of the electric tricycle. Installation parts are pre-set at the four corners, bottom, side and other required parts of the box body 1 of the refrigerated box for subsequent docking with the electric tricycle.

[0020] As Figure 1 and Figure 2 shown, the refrigerated box is designed with a front-mounted compressor. Therefore, the front end is the freezer 2 and the rear end is the refrigerator 3. Because the compressor is set at the front end, an evaporator is provided in the freezer 2, and the space of the freezer 2 is necessarily larger than that of the refrigerator 3. As Figure 3 and Figure 4As shown in the figure, two connected circulating air holes 4 are provided on the heat-insulating wall of the refrigerating chamber 3 for circulating and transporting cold air. The two circulating air holes 4 are vertically aligned. The upper end of the upper circulating air hole 4 is aligned with the height of the upper hinge of the cabinet door 5, and the lower end of the lower circulating air hole 4 is aligned with the bottom surface height of the cabinet door 5. In this way, the cold air can not only circulate in the refrigerating chamber 3, but also form a circulating air duct with a relatively lower center, which is more in line with the actual use of the refrigerating chamber 3, and the cold air enters from the top and exits from the bottom.

[0021] As Figure 5 As shown in the figure, the freezer 2 and the refrigerating chamber 3 are provided with separate cabinet doors 5 on the side, and the cabinet door 5 is a magnetic door. The cabinet door 5 includes a set of magnetic fixing seats 6 and magnetic handles 7. A magnetic component is provided on the right side of the magnetic fixing seat 6, and a sealing strip is provided at the left end of the magnetic handle 7. The sealing strip is also a magnetic component and can be used in cooperation with the magnetic fixing seat 6 to form a medium for magnetic triggering. The cross-section of the cabinet door 5 is a convex-shaped structure, and the corresponding door groove of the cabinet door is a stepped groove body. The magnetic sealing strip can fill the left-right gap between the cabinet door 5 and the cabinet body 1. A buffer member 8 is provided at the left-back position on the back of the cabinet door 5. The buffer member 8 does not contact the cabinet body 1 when the cabinet door 5 is closed. The buffer member 8 can fill part of the front-back gap between the cabinet door 5 and the cabinet body 1, mainly to prevent the impact between the cabinet door 5 and the cabinet body 1 caused by closing the door too fast or with too much force.

[0022] It should be noted that this specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
