[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7 As shown, a cold storage refrigeration device includes a device body, a refrigeration system, and a power supply system. The device body includes a shell 10 and an inner liner 20. The inner liner 20 has a refrigeration chamber 21 for refrigerating and / or freezing food to preserve it. The shell 10 is fitted around the outer periphery of the inner liner 20, and a receiving cavity 30 is formed between the shell 10 and the inner liner 20. The receiving cavity 30 houses a plurality of cold storage ice boxes 40. The refrigeration system includes a compressor and an evaporator coil 50. The evaporator coil 50 is arranged around the outer periphery of the inner liner 20 and is located between the cold storage ice boxes 40 and the inner liner 20, and is in contact with the cold storage ice boxes 40 and the inner liner 20. The evaporator coil 50 provides cooling capacity to the cold storage ice boxes 40 and the refrigeration chamber 21. The power supply system provides electrical energy for the operation of the compressor and other components.

[0026] Both the outer shell 10 and the inner liner 20 are conventional shapes, such as round, rectangular, square, etc. The outer shell 10 and the inner liner 20 are preferably rectangular. The outer shell 10 is provided with a flip cover 60 and a cover plate 70. The cover plate 70 is fixed on the receiving cavity 30 to close the receiving cavity 30. The flip cover 60 is hinged to the outer shell 10 so that the flip cover 60 can cover the outer shell 10 and the inner liner 20 to close the refrigeration cavity 21. The flip cover 60 can rotate relative to the refrigeration cavity 21 to open or close the refrigeration cavity 21, which facilitates the storage and removal of food. Of course, the flip cover 60 can also be a segmented sliding door. The setting method of the sliding door is the same as the prior art, and will not be described in detail here. The outer shell 10 below the inner liner 20 is also provided with a working cavity, in which the compressor and other components are housed. The refrigeration principle of the main body of the device and the compressor is the same as that of the existing refrigeration cabinet, and will not be described in detail here. In this embodiment, the cold storage ice box 40 includes a box body 41, a box opening 42 provided on the box body 41, and a box cover 43 assembled on the box opening 42 and sealing the inner cavity of the box body 41. The inner cavity of the box body 41 is filled with a phase change cold storage agent. The freezing point of the phase change cold storage agent is not higher than -15°C, preferably not higher than -30°C, and most preferably not higher than -45°C, so as to ensure that the refrigeration chamber 21 can maintain a suitable refrigeration temperature for a long time under the action of the phase change cold storage agent. Ideally, under the action of the phase change cold storage agent, the refrigeration temperature in the refrigeration chamber 21 can be maintained for more than 12 hours. The refrigeration temperature is generally -1°C to 8°C. The box body 41 is also rectangular and is arranged around the outer periphery of the inner liner 20. Specifically, there are four cold storage ice boxes 40. Each cold storage ice box 40 is arranged opposite to the end face of the inner liner 20, and adjacent cold storage ice boxes 40 abut against each other.

[0027] The box body 41 has several slots 44 on the side near the inner liner 20. The slots 44 extend along the length of the box body 41 and are recessed from the side of the box body 41 near the inner liner 20 away from the inner liner 20. The evaporator coil 50 is fitted into the slot 44, so that the evaporator coil 50 is semi-enclosed by the slot 44 and is in contact with the inner liner 20. This arrangement prevents the evaporator coil 50 from separating from the box body 41 and from the inner liner 20, especially at freezing temperatures, and does not waste the cooling capacity generated by the evaporator coil 50.

[0028] The inner wall of the shell 10 and the cold storage ice box 40 are filled with thermal insulation cotton 80. The thermal insulation cotton 80 can not only reduce the loss of cold energy to the outside, but also play a certain role in fixing the cold storage ice box 40.

[0029] In another embodiment, a buffer is provided between the box body 41 and the inner liner 20 on the side near the inner liner 20. The buffer can be a spring, or a shock-absorbing rubber part or shock-absorbing cotton with shock absorption function. With this arrangement, the buffer works together with the insulation cotton 80 to further prevent the evaporation coil 50, the inner liner 20 and the box body 41 from separating when the phase change refrigerant turns into ice.

[0030] In another embodiment, please refer to Figure 2 , 6 As shown in Figure 7, several grooves 45 are provided on both sides of the length of the box body 41. The grooves 45 on the same side are generally located between adjacent slots 44 and are evenly distributed along the length of the box body 41. The grooves 45 on both sides of the box body 41 correspond one to one and are connected to each other to prevent the side of the box body 41 from bulging after the phase change refrigerant is poured in.

[0031] The power supply system can include solar panels or mains power. Of course, both solar panels and mains power can coexist. Regardless of which method is chosen, the power supply system mainly provides power for the operation of components such as compressors.

[0032] When this refrigeration equipment is used in areas with sufficient mains power, the cold storage ice box 40 can provide cooling to the refrigeration chamber 21 in the event of a circuit failure or temporary power outage, preventing the food inside the refrigeration chamber 21 from spoiling. When this refrigeration equipment is used in areas with scarce mains power, during the day, solar panels can be used to provide power for the operation of components such as the compressor, thereby providing cooling to the refrigeration chamber 21 and the cold storage ice box 40. At night, when there is no external power supply such as solar energy, the cold storage ice box 40 can be used to provide cooling to the refrigeration chamber 21. Regardless of the situation, there is no need to install an energy storage battery in the refrigeration equipment, eliminating the need for energy storage battery maintenance, reducing maintenance costs, and the service life of the cold storage ice box 40 is unlimited, extending the service life of the refrigeration equipment, which is especially convenient for use in areas with power shortages.

[0033] This utility model has been described through several specific embodiments. Those skilled in the art should understand that various modifications and equivalent substitutions can be made to this utility model without departing from its scope. Furthermore, various modifications can be made to this utility model for specific situations or circumstances without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.
