[0030] As Figures 1-5 shown, the present application provides a refrigeration refrigerator, which includes a cabinet 100, a refrigeration module 200, and a power supply module 300.

[0031] The inside of the box body 100 is provided with a storage space 110 and a refrigeration cavity 120, the storage space 110 and the refrigeration cavity 120 are in communication with each other, and the refrigeration module 200 is arranged in the refrigeration cavity 120 to refrigerate the storage space 110. Specifically, the refrigeration module 200 includes a compressor 210, a condenser 220, a capillary tube 230, a refrigeration fan 240, and an evaporator 250 for refrigerating the refrigeration cavity 120, the compressor 210, the condenser 220, the capillary tube 230, and the evaporator 250 are connected with each other through refrigeration pipelines, the compressor 210 is adapted to compress the normal-temperature gaseous refrigerant into high-temperature gaseous refrigerant, the condenser 220 is adapted to liquefy the high-temperature gaseous refrigerant into normal-temperature liquid refrigerant, the normal-temperature liquid refrigerant flows to the evaporator 250 after being throttled and decompressed by the capillary tube 230, the normal-temperature liquid refrigerant is gasified into normal-temperature gaseous refrigerant at the evaporator 250, and the refrigerant gasification process absorbs heat to reduce the temperature in the refrigeration cavity 120, and the normal-temperature gaseous refrigerant finally flows back to the compressor 210 for next cycle. The refrigeration cavity 120 is in communication with the storage space 110 through an air inlet channel 130 and an air return channel 140, and the refrigeration fan 240 can drive the cold air in the refrigeration cavity 120 to flow into the storage space 110 through the air inlet channel 130, and drive the hot air in the storage space 110 to flow into the refrigeration cavity 120 through the air return channel 140, to complete the refrigeration of the storage space 110. Preferably, the evaporator 250 is implemented as a finned evaporator, and when the refrigeration refrigerator is running, the moisture in the air circulating between the refrigeration cavity 120 and the storage space 110 can be precipitated as frost on the surface of the finned evaporator, ensuring that the air is dry and avoiding the phenomenon of frosting in the storage space 110.

[0032] The refrigeration module 200 is powered by a power supply module 300, the power supply module 300 includes three battery mounting portions 310, the three battery mounting portions 310 are arranged on the outer side wall of the box body 100, and the three battery mounting portions 310 are arranged on the outer side wall of the box body 100 away from the refrigeration module 200, to avoid the heat generated by the charging and discharging of the battery pack 340 and the heat generated by the working of the refrigeration module 200 from being accumulated, causing the battery pack 340 and the refrigeration module 200 to be unable to work normally.

[0033] As Figures 1-2As shown, the three battery mounting portions 310 can be implemented as one first battery compartment 311 and two second battery compartments 312, the first battery compartment 311 and the second battery compartment 312 are different in shape and size to adapt to different models of battery packs 340, for example, the first battery compartment 311 is adapted to the battery pack 340 of the mobile energy storage power supply, and the second battery compartment 312 is adapted to the battery pack 340 of the power tool, the first battery compartment 311 and the second battery compartment 312 are provided with power supply terminals 320, the power supply terminals 320 are circuit-connected to the refrigeration module 200, the battery pack 340 is inserted into the first battery compartment 311 and the second battery compartment 312 in a locked manner, and the insertion direction of the battery pack 340 is parallel to the direction of the outer side wall end face of the box body 100, when the battery pack 340 is locked in the first battery compartment 311 and the second battery compartment 312, the battery pack 340 is circuit-connected to the power supply terminals 320, and then the battery pack 340 is circuit-connected to the refrigeration module 200 to supply power to the refrigeration module 200. The specific type of the battery pack 340 is not limited, and the battery pack 340 can be implemented as a lithium ion battery pack 340, or as an alkaline battery pack 340 or other power supply sources that can be repeatedly charged and discharged.

[0034] In other embodiments, the power supply terminals 320 in the second battery compartment 312 are not directly circuit-connected to the refrigeration module 200, but are circuit-connected to the power supply terminals 320 in the first battery compartment 311 through a connecting line, so as to realize the circuit connection between the power supply terminals 320 in the second battery compartment 312 and the refrigeration module 200.

[0035] It is worth mentioning that the first battery compartment 311, the second battery compartment 312 and the battery pack 340 are arranged on the outer side wall of the box body 100, and the battery pack 340 does not occupy the space inside the box body 100, thereby optimizing the internal structure of the box body 100, so that the components of the refrigeration module 200 can be reasonably arranged, and the storage space 110 inside the box body 100 can be as large as possible.

[0036] Further, a communication terminal 330 is arranged in each of the first battery compartment 311 and the second battery compartment 312, and is circuit-connected with a control module (not shown in the figure) of the refrigeration refrigerator. When the battery pack 340 is inserted into the first battery compartment 311 and the second battery compartment 312 in a locked manner, the battery pack 340 is circuit-connected with the communication terminal 330 and the power supply terminal 320 at the same time, and then the battery pack 340 is circuit-connected with the control module. The control module can receive the power information of the battery pack 340 and control the battery pack 340 with low power to supply power to the refrigeration module 200 preferentially. When the power of the battery pack 340 is consumed, the control module automatically switches to another battery pack 340 to supply power. The battery pack 340 with consumed power can be replaced and charged by an energy storage device or a charging device. The plurality of battery packs 340 supply power to the refrigeration module 200 alternately, so that uninterrupted power supply to the refrigeration module 200 is realized, and the phenomenon of shutdown of the refrigeration module 200 is avoided.

[0037] Further, the power supply module 300 comprises a power supply interface 350 arranged on the outer side wall of the cabinet 100 and arranged on the same side wall as the battery mounting portion 310. The power supply interface 350 is circuit-connected with the power supply terminal 320 in the first battery compartment 311 and the second battery compartment 312, and then the power supply interface 350 can be circuit-connected with a vehicle power supply, a mobile energy storage power supply, etc. through a power supply connection line to supply power to the battery pack 340 and the refrigeration module 200. The power supply interface 350 can be implemented as a DC interface or an AC interface. The DC interface can be implemented as a common TYPE-C interface, a triangular interface or a USB interface, etc.

[0038] For example, the external power supply can be implemented as a solar panel (not shown in the figure). The solar panel is connected with the power supply interface 350 through a power supply line. The solar panel is adapted to convert solar energy into electric energy to supply power to the refrigeration module 200 and the battery pack. During use of the refrigeration refrigerator, the solar panel is irradiated by sunlight to generate electric current. The electric current can supply power to the refrigeration module 200 or charge the battery pack 340.

[0039] As shown in Figure 4 The storage space 110 further comprises three temperature sensors 400 circuit-connected with the control module. The temperature sensors 400 are adapted to measure the temperature of the storage space 110 and transmit the measured temperature signal to the control module. The control module is adapted to adjust the power of the refrigeration module 200 according to the difference between the temperature signal and a preset temperature. The three temperature sensors 400 are arranged at the communication position of the storage space 110 and the air inlet channel 130, the communication position of the storage space 110 and the air return channel 140, and the center of the storage space 110, respectively. The control module can comprehensively compare the temperature signals measured by the three temperature sensors 400, and switch the refrigeration module 200 between the energy-saving mode, the variable frequency mode and the high-energy mode.

[0040] Wherein:

[0041] Energy-saving mode: the compressor 210 in the refrigeration module 200 continuously refrigerates at the lowest power, the refrigeration module 200 does not suspend refrigeration, reduces the number of starts and stops of the compressor 210, prolongs the service life of the compressor 210, and saves energy;

[0042] Variable frequency mode: the compressor 210 in the refrigeration module 200 automatically adjusts the power according to the difference between the actual temperature and the set temperature, so that the temperature in the storage space 110 fluctuates within a small range, and the power adjustment realizes smooth refrigeration, and adapts to different refrigeration needs;

[0043] High-energy mode: the compressor 210 in the refrigeration module 200 operates at high power or maximum power, quickly reduces the temperature in the storage space 110, and when the temperature in the storage space 110 reaches the set value, the compressor 210 stops operating and enters standby state, which is suitable for situations requiring rapid cooling and ensures that food quickly reaches a safe storage temperature.

[0044] Further, the refrigeration refrigerator further comprises a display module (not shown in the figure), the display module is arranged on the outer surface of the cabinet 100, the display module is in circuit connection with the control module and the refrigeration module 200, and the display module is suitable for displaying the power of each battery pack 340, the working state of the refrigeration module 200 and the like.
