[0081] It should be noted that the disassembly tool 218 is preferably an Allen wrench, used to disassemble and assemble the connecting part 3. A buckle is installed on the inner end face of the refrigerator door 204 to lock and fix the disassembly tool 218, which can be removed when needed.
[0082] It should be noted that the pallet 220 preferably has a metal mesh structure; the pallet 220 support 219 is preferably installed in pairs at the middle and upper parts of the inner end face of the first chamber end wall 205 and the second chamber end wall 206. In the unfolded state, the pallet 220 is installed in the middle pallet 220 support 219, and in the folded state, the pallet 220 is installed in the upper pallet 220 support 219, providing storage space for the box base 1.
[0083] It should be noted that the support block groove 221 can cooperate with the support block 119. In the folded state, the cabinet 1 is inserted into the refrigerator compartment 2. Rotating the support block 119 outwards so that it pushes into the support block groove 221 can fix the cabinet 1.
[0084] It should be noted that during the process of storing the cabinet 1 in the refrigerator compartment 2, the positioning feet 118 of the cabinet 1 can be pushed inward along the positioning groove 222. When all four positioning feet 118 fall into the positioning foot groove 223, it indicates that the cabinet 1 is in place.
[0085] In specific implementation, the air outlet baffle 212 and return air outlet baffle 213 can prevent dust from entering the refrigerator compartment 2 and ensure food hygiene; the upper surface of the top plate 201 is provided with the same number and corresponding position of the compartment support mounting parts 215, which facilitates the stacking of multiple refrigerator boxes during transportation; the refrigerator compartment door 204 is equipped with disassembly and assembly tools 218 to facilitate the disassembly and assembly of the refrigerator compartment 2 and the box base 1, making the unfolding and folding processes faster and more convenient; the pallet 220 can divide the space of the refrigerator compartment 2, which is convenient for food storage and retrieval; two pairs of pallet 220 brackets 219 are provided, which can place the pallet 220 on the upper layer in the folded state to provide storage space for the box base 1; the sliding groove and positioning support groove 223 can be set to position more quickly and accurately during the storage process.
[0086] In one implementation, such as Figure 5 As shown, the second region 109 is divided by a baffle into a central equipment area 124, a fan area 125 near the front wall 103 of the seat, and a storage area 126 near the rear wall 104 of the seat; the refrigeration unit 4 includes a compressor 401 and a condenser assembly 402 arranged in the first region 108, and an evaporator assembly 403 arranged in the equipment area 124; the compressor 401, the condenser assembly 402, and the evaporator assembly 403 are interconnected by pipelines.
[0087] It should be noted that the partition 107 is preferably made of aluminum alloy and is preferably fixed to the inner wall of the box base 1 by welding.
[0088] It should be noted that the refrigeration unit 4 includes a compressor 401, a condenser assembly 402, and an evaporator assembly 403, all of which are existing technologies and are not limited here. The present invention preferably uses a horizontal rotor compressor 401, an evaporator in the form of aluminum tube corrugated aluminum fins, and a condenser in the form of microchannels. The refrigeration unit 4 as a whole has the characteristics of high energy efficiency, light weight, high heat exchange efficiency, excellent shock absorption performance, and long service life.
[0089] In practice, the second area 109 is divided into an equipment area 124, a fan area 125, and a storage area 126, which can make better use of space and is conducive to the overall structural optimization of the refrigerator.
[0090] In one implementation, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the refrigerator also includes an airflow unit 5; the airflow unit 5 includes:
[0091] The fan is located in the fan area 125;
[0092] A trigger switch 501 is installed on the edge of the first chamber end wall 205 near the refrigerator door 204 and is electrically connected to the fan and the power controller 115 respectively.
[0093] The air duct 502 has a first end connected to the air outlet of the fan, and a second end extending upward to the top plate 101.
[0094] The top plate 101 is provided with a first air wall opening 503 through the front wall 103 of the seat near the edge of the top plate 101; the lower end of the first air wall opening 503 is connected to the second end of the air guide pipe 502.
[0095] The floor 202 has a second air wall opening 504 that penetrates the floor 202; the second air wall opening 504 is positioned opposite to the first air wall opening 503 and is equal in size; in the unfolded state: the second air wall opening 504 is connected to the first air wall.
[0096] It should be noted that existing refrigerators frequently open and close the refrigerator door 204 during use, increasing heat exchange and causing cold air loss. This is especially true in outdoor environments where the refrigerator compartment 2 is relatively small, making internal cold air loss even more likely. Therefore, this invention provides a wind wall unit 5 structure: a horizontal airflow (wind wall) is formed upwards from the bottom of the refrigerator compartment 2 near the edge of the refrigerator door 204. When the refrigerator door 204 is opened, the trigger switch 501 is released, connecting the power supply, the fan starts, and the airflow rises along the air duct 502, passes through the first wind wall opening 503 and the second wind wall opening 504, and blows upwards, forming a horizontal airflow. This horizontal airflow can act like a wall at the refrigerator door 204 opening to prevent cold air from escaping, but does not affect the storage and retrieval of food, thus effectively preventing the loss of internal cold air. After the refrigerator door 204 is closed, the trigger switch 501 is pressed to turn off the power supply, and the wind wall automatically disappears.
[0097] It should be noted that the trigger switch 501 and the fan are both existing technologies and are not limited here; the trigger switch 501 is preferably a push-button switch, which is pressed down to disconnect the power when the refrigerator door 204 is closed, and popped up when the refrigerator door 204 is opened to connect the power; the fan is preferably a small centrifugal fan, which has the advantages of small size and large air volume.
[0098] It should be noted that the air duct 502 is preferably made of nylon. One end is connected to the air outlet of the fan, and the other end gradually transitions into a long strip pipe opening and connects to the lower end of the first air wall opening 503.
[0099] In practice, the air wall unit 5 can effectively prevent the loss of cold air during the opening and closing of the refrigerator door 204, so that the refrigerator can have a better cooling effect and be more energy-efficient; the cold air is concentrated at the bottom of the refrigerator 2, and the air wall is arranged from bottom to top, which can more effectively prevent the cold air from being lost from the bottom.
[0100] In the embodiments provided by the present invention, such as Figure 7 As shown, the second air wall opening 504 has the same length as the internal space of the refrigerator in the length direction, and an air guide plate 505 is placed inside it at an angle to the vertical direction.
[0101] It should be noted that the air guide plate 505 is preferably made of aluminum alloy and is fixed inside the second air wall opening 504 by rivets or screws. Its upper end has an outward tilt angle with the vertical direction, which can be 3° to 15°, and 3° is preferred here.
[0102] In practice, the first air wall opening 503 and the second air wall opening 504 are the same size. The length of the second air wall opening 504 is the same as the internal length of the refrigerator, which can make the air wall fill the two openings of the refrigerator compartment and better prevent cold air from escaping.
[0103] The outward-sloping air guide plate 505 can tilt the air wall to the outside of the refrigerator compartment 2, preventing it from blowing into the interior of the refrigerator compartment 2 and causing cold air to be blown out of the refrigerator compartment 2.
[0104] In one embodiment, the lower end face of the ceiling plate 201 is provided with a plurality of slots; a cold storage ice crystal box is movably installed in the slots, which is not shown in the figure.
[0105] It should be noted that the slots are preferably installed on the lower end face of the ceiling plate 201 by screws or rivets; the number of slots can be 3 to 8, and the present invention preferably has 6; an equal number of cold storage ice crystal boxes are movably installed in the slots, which can be removed or installed at any time.
[0106] It should be noted that the cold storage ice crystal box is made of food-grade thickened PE material; the ice crystal box is filled with cold storage ice crystals; the cold storage ice crystals have a freezing point of -20℃, and have the characteristics of short freezing time, high cold storage capacity, reusability without water injection, and unlimited number of uses as long as the packaging is not damaged. When the cold storage ice crystals melt after freezing, the cold energy released is much greater than that of water, which directly plays a role in rapid cooling. Under full load conditions, it can maintain ≤10℃ inside the box for 24 hours after power failure (ambient temperature 46℃, initial temperature -10℃), which can meet the cold storage and insulation needs under tight power supply conditions in the field.
[0107] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
