[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a dual-refrigeration module alternating cycle refrigerator.

[0025] Example 1

[0026] For ease of understanding, please refer to Figures 1 to 4. An embodiment of a dual-refrigeration module alternating circulation refrigerator provided by this utility model includes an inner liner 1, an outer shell 2 fixedly installed on the outer wall of the inner liner 1, a door 3 movably installed on one side of the outer shell 2, two breathable mesh plates 4 fixedly installed on the inner side of the inner liner 1, two refrigeration systems 5 and a main controller 6 arranged between the inner liner 1 and the outer shell 2, the refrigeration system 5 including an evaporator 504, and an air circulation assembly arranged between the inner liner 1 and the outer shell 2;

[0027] It should be noted that the main controller 6 is used to control the operation of two independent refrigeration systems 5. Under the action of the main controller 6, the two refrigeration systems 5 will work alternately according to a preset strategy. For example, when the temperature inside the refrigerator is too high, the two refrigeration systems 5 will be controlled to work simultaneously for rapid cooling. When constant temperature is required, only one refrigeration system 5 will be controlled to work for heat preservation. In addition, the refrigerator is equipped with multiple temperature sensors that are electrically connected to the main controller 6 to monitor the temperature inside the refrigerator in real time.

[0028] The air circulation assembly includes two heat exchange boxes 701, two filter modules 702, two suction pipes 703, and a suction fan 704. The two heat exchange boxes 701 are fixedly installed on one side of the two ventilated mesh plates 4. The two filter modules 702 are both located between the inner liner 1 and the outer shell 2. The suction fan 704 is fixedly installed on the top of the inner liner 1. The suction pipe 703 is fixedly installed between the suction fan 704 and the filter module 702. One end of the suction pipe 703 is connected to the suction end of the suction fan 704. The output end of the suction fan 704 is located on the inner side of the top of the inner liner 1. The output end of the filter module 702 is connected to one end of the suction pipe 703. The input end of the filter module 702 is connected to the inside of the heat exchange box 701 through a pipe.

[0029] It should be noted that by setting up a heat exchange box 701 and an exhaust fan 704, the heat exchange box 701 and the exhaust fan 704 are connected by a filter module 702 and an exhaust pipe 703. When in use, the refrigeration system 5 starts to cool. The evaporator 504 of the refrigeration system 5 vaporizes and absorbs heat. At this time, the exhaust fan 704 works to draw in the air, so that the internal air enters the heat exchange box 701 through the breathable mesh plate 4 for heat exchange. Then, it passes through the filter module 702 and is transported to the inner liner 1 by the exhaust fan 704 through the exhaust pipe 703. This cycle continues, so that the internal air is constantly in contact with the evaporator 504 for rapid heat exchange, thereby improving the cooling efficiency.

[0030] In some embodiments, as shown in Figures 2 and 4, the evaporator 504 is located inside the heat exchange box 701, and the refrigeration system 5 also includes a compressor 501, a condenser 502 and an expansion valve 503. The compressor 501 is electrically connected to the main controller 6 by wires.

[0031] It should be noted that the refrigeration cycle of refrigeration system 5 is as follows: refrigerant vapor is compressed into high-temperature and high-pressure vapor in compressor 501; the high-temperature and high-pressure refrigerant vapor releases heat to the cooling medium in condenser 502, condensing into high-pressure and room-temperature liquid refrigerant; the high-pressure liquid refrigerant is throttled and depressurized through expansion valve 503, becoming low-pressure and low-temperature liquid refrigerant; the low-pressure and low-temperature liquid refrigerant absorbs heat from the cooled medium in evaporator 504 and vaporizes, achieving the refrigeration effect. These four processes are repeated continuously, constantly absorbing heat from the cooled medium and releasing heat to the cooling medium through condenser 502, thereby achieving the purpose of refrigeration. This technical means is an existing means and will not be elaborated here.

[0032] Example 2

[0033] In some embodiments, as shown in FIG2, the filter module 702 includes a mounting box 7021, a partition 7022, and an activated carbon filter 7025. The mounting box 7021 is fixedly installed between the inner liner 1 and the outer shell 2. The partition 7022 is fixedly connected to the inner side of the mounting box 7021. An air inlet chamber 7023 and an exhaust chamber 7024 are opened on the inner side of one end of the mounting box 7021. The activated carbon filter 7025 is fixedly installed on the inner side of one end of the mounting box 7021. The activated carbon filter 7025 is located at one end of the partition 7022. The air inlet chamber 7023 and the exhaust chamber 7024 are located on both sides of the partition 7022.

[0034] It should be noted that by setting up the installation box 7021 and installing the partition 7022 inside the installation box 7021, an air intake chamber 7023 and an exhaust chamber 7024 are formed inside. An activated carbon filter 7025 is installed in the passage of the air intake chamber 7023 and the exhaust chamber 7024. During the air circulation inside the refrigerator, the air passes through the installation box 7021 of the filter module 702, and the activated carbon filter 7025 inside the installation box 7021 adsorbs unpleasant odors, which facilitates the removal of odors inside the refrigerator.

[0035] Working principle: When in use, the refrigeration system 5 starts to cool. The evaporator 504 of the refrigeration system 5 vaporizes and absorbs heat. At this time, the suction fan 704 works to draw in the air, which passes through the breathable mesh plate 4 and enters the heat exchange box 701 for heat exchange. Then, it passes through the filter module 702 and is delivered to the inner liner 1 by the suction pipe 703 from the output end of the suction fan 704. This cycle continues, allowing the internal air to continuously contact the evaporator 504 for rapid heat exchange and improved cooling efficiency. At the same time, during the air circulation inside the refrigerator, the air passes through the installation box 7021 of the filter module 702, where the activated carbon filter 7025 inside the installation box 7021 adsorbs unpleasant odors, making it easy to remove odors from inside the refrigerator.

[0036] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
