[0050] In order to solve the problem of poor fresh-keeping performance of mobile cold storage equipment in the prior art, the present application provides a mobile fresh-keeping equipment and a mobile fresh-keeping equipment control method.

[0051] Example 1

[0052] like Figures 1 to 5 As shown, the mobile fresh-keeping equipment includes a cabinet 10, a refrigeration component, an air supply duct 30 and a fan 70. Among them, the cabinet 10 has a first circulation air duct and a second circulation air duct, and the first circulation air duct is located above the second circulation air duct. The refrigeration component includes a refrigerator 20 located in the first circulation air duct. The air supply duct 30 is arranged in the cabinet 10, and the air supply duct 30 has an air inlet and an air outlet 31. The air inlet is connected to at least part of the air outlet of the refrigerator 20. The cold air blown out from the refrigerator 20 passes through the air inlet and the air outlet in sequence and then enters the first circulation air duct. The fan 70 is arranged in the second circulation air duct and is located below the refrigerator 20.

[0053] By applying the technical solution of this embodiment, the cold air generated by the refrigerator first enters the air inlet of the air supply duct 30, and then is discharged into the cabinet 10 through the air outlet 31 of the air supply duct 30, and then blows cold air to the fruits and vegetables to be preserved stored in the cabinet 10 to cool them down and preserve them. After completing the cooling and preservation, the air flow enters the refrigerator 20 again, so that the air flow flows in the first circulation air duct, and a first circulation path is formed between the refrigerator 20, the air supply duct 30 and the cabinet 10. The air inlet and outlet of the fan 70 are both located below the refrigerator 20. The air flow blown out from the outlet of the fan 70 can flow back to the air inlet of the fan 70 after passing through the fruits and vegetables to be preserved, so that the air flow flows in the second circulation duct and forms a second circulation path between the fan 70 and the cabinet 10. The second circulation path is located below the first circulation path and disturbs the gas located below the cabinet 10 to make the cold air in the cabinet 10 more uniform, thereby realizing full-area penetration air supply in the cabinet 10, avoiding cold air directly blowing on the surface of the fruits and vegetables to be preserved, so as to send cold air to every corner of the cabinet, and the air supply is uniform, reducing the surface dryness of the fruits and vegetables to be preserved and reducing water loss, thereby solving the problem of poor preservation performance of mobile cold storage equipment in the existing technology and improving the storage rate of good fruits.

[0054] In this embodiment, the refrigerator itself includes a refrigeration fan.

[0055] Optionally, the refrigerator 20 is an angle air cooler.

[0056] like Figures 3 to 5 As shown, the mobile fresh-keeping equipment further includes a first partition structure 50. The first partition structure 50 is disposed between the refrigerator 20 and the fan 70. The upper surface of the first partition structure 50 forms at least a portion of the duct wall of the first circulation air duct, and the lower surface of the first partition structure 50 forms at least a portion of the duct wall of the second circulation air duct. In this way, the first circulation air duct and the second circulation air duct are separated by the first partition structure 50 so that the two circulation air ducts do not interfere with each other. The first circulation air duct located at a higher position is used to discharge cold air. Since cold air tends to accumulate at the lower part of the cabinet 10, the second circulation air duct located at a lower position can disturb the cold air at the lower part of the cabinet 10 to improve the uniformity of the cold air in the cabinet 10.

[0057] like Figures 3 to 5 As shown, the mobile fresh-keeping equipment further includes a second partition structure 100, one end of which extends to the inner top surface of the refrigerator 20 or the cabinet 10, and the other end of the second partition structure 100 extends to the inner bottom surface of the cabinet 10, so as to divide the inner cavity of the cabinet 10 into a first installation cavity 111 and a storage cavity 112. The first partition structure 50 is located on one side of the second partition structure 100 and is connected to the second partition structure 100, so that a first circulation air duct is formed between the upper surface of the first partition structure 50 and at least a portion of the second partition structure 100 and at least a portion of the inner surface of the cabinet 10, and a second circulation air duct is formed between the lower surface of the first partition structure 50 and at least another portion of the second partition structure 100 and at least a portion of the inner surface of the cabinet 10. In this way, on the one hand, the above-mentioned setting makes the formation of the first circulation air duct and the second circulation air duct easier and simpler, reducing the processing cost and difficulty; on the other hand, it ensures that the first circulation air duct and the second circulation air duct are set independently of each other, respectively used for discharging cold air and disturbing the cold air, and will not interfere with each other to cause turbulence of the cold air in the cabinet 10 and generate vibration and noise.

[0058] like Figures 3 to 5 As shown, the second partition structure 100 has a first ventilation hole 101, through which the air outlet and / or air inlet of the fan 70 communicate with the storage chamber 112. This arrangement allows the fruits and vegetables to be preserved and the air outlet 31 of the air supply duct 30 to be located within the storage chamber 112, while the remaining components are located within the second mounting chamber 121 and the first mounting chamber 111. This makes the internal structure of the cabinet 10 more rational and compact, significantly increasing the storage space for fruits and vegetables to be preserved within the cabinet body 11. Furthermore, this arrangement ensures the normal operation of the fan 70 and improves its operational reliability.

[0059] In this embodiment, the two ends of the second partition structure 100 extend to the inner bottom surface of the refrigerator 20 and the cabinet 10, respectively, to divide the cabinet 10 into two left and right chambers, namely a first installation chamber 111 and a storage chamber 112. The sterilizer 40, humidifier 60, and fan 70 are located in the first installation chamber 111, and the fruits and vegetables to be preserved and the air supply duct 30 are located in the storage chamber 112. At the same time, the air outlet of the fan 70 is connected to the storage chamber 112 through the first ventilation hole 101, ensuring that the airflow blown out from the fan 70 can be blown into the storage chamber 112 through the first ventilation hole 101.

[0060] It should be noted that the connection relationship of the second partition structure 100 is not limited to this and can be adjusted according to working conditions and usage requirements. In other embodiments not shown in the drawings, the two ends of the second partition structure extend to the inner top and bottom surfaces of the cabinet, respectively, to divide the cabinet into two left and right chambers. In this case, the refrigerator, sterilizer, humidifier, and fan are located in the first installation chamber, and the fruits and vegetables to be preserved and the air outlet of the air supply duct are located in the storage chamber.

[0061] like Figures 3 to 5 As shown, the first partition structure 50 has a liquid storage recess, which is used to collect the condensed water flowing through the refrigerator 20. The gas flowing through the refrigerator 20 and the air flow flowing through the fan 70 are separated by the first partition structure 50. In this way, during the operation of the refrigerator 20, the condensed water generated on its surface can flow into the first partition structure 50 for buffering, and serve as a water source for the humidifier 60. This not only achieves the reuse of resources and avoids resource waste, but also prevents the condensed water from flowing into the cabinet and causing spoiled fruits. At the same time, the first partition structure 50 plays the role of structural and airflow separation, so that the air inlet and air inlet channel of the fan 70 and the air inlet and outlet paths of the refrigerator 20 are independent of each other and do not affect each other, and there will be no interference between the air flows, thereby ensuring that the first circulation path and the second circulation path can be distributed in the height direction of the cabinet 10, realizing full-area infiltration air supply in the cabinet 10, avoiding the cold air from blowing directly on the surface of the fruits and vegetables to be preserved and causing water loss, and improving the preservation performance of the mobile cold storage equipment.

[0062] Specifically, the condensed water generated by the refrigerator 20 flows into the first partition structure 50 through the pipeline, so that the condensed water is buffered by the first partition structure 50 .

[0063] like Figures 3 to 5As shown, the first partition structure 50 has a drainage hole connected to the liquid storage recess. The mobile fresh-keeping equipment also includes a humidifier 60. The drainage hole is connected to the liquid inlet of the humidifier 60 to supply liquid to the humidifier 60. In this way, when the humidifier 60 is needed to humidify the airflow within the cabinet 10, the humidifier 60 is activated. The water source for the humidifier 60 comes from the drainage hole of the first partition structure 50. This not only achieves the purpose of humidifying the fruits and vegetables to be preserved, but also allows the water source to be reused, avoiding resource waste.

[0064] Optionally, the first partition structure 50 is a water receiving tray.

[0065] Optionally, the fan 70 is used to blow the water mist discharged from the outlet of the humidifier 60 toward the fruits and vegetables to be preserved; and / or the air inlet and outlet of the fan 70 are both connected to the inner cavity of the cabinet 10. In this way, the above configuration makes the fan 70 more versatile. That is, when the humidifier 60 is activated, the fan 70 blows the water mist produced by the humidifier 60 toward the fruits and vegetables to be preserved to humidify them; when the humidifier 60 is not activated, the fan 70 disturbs the airflow below the first circulation path and forms a second circulation path, thereby achieving full-area permeation air supply within the cabinet 10.

[0066] In this embodiment, when the humidity value in the cabinet 10 is less than or equal to the second preset humidity S2, the humidifier 60 is started, and the fan 70 blows the water mist generated by the humidifier 60 toward the fruits and vegetables to be preserved, thereby humidifying the surface of the fruits and vegetables to be preserved to increase the surface humidity of the fruits and vegetables to be preserved; when the humidity value in the cabinet 10 is greater than or equal to the first preset humidity S1, the humidifier 60 is turned off, and the air flow flows between the fan 70, the cabinet 10 and the fruits and vegetables to be preserved, so that the fan 70 disturbs the air flow below the first circulation path, thereby realizing full-area infiltration air supply in the cabinet 10.

[0067] like Figures 3 to 5 As shown, the mobile fresh-keeping equipment also includes a sterilization device 40. The sterilization device 40 is arranged in the cabinet 10 and is connected to the air inlet and / or at least part of the air outlet of the refrigerator 20, so as to sterilize and disinfect the airflow passing through the refrigerator 20. Among them, the sterilization device 40 is arranged on the first partition structure 50. In this way, after the sterilization device 40 is started, the sterilization device 40 can sterilize the airflow in the cabinet 10 to prevent bacteria from growing on the surface of the fruits and vegetables to be preserved and affecting the good fruit rate and even food safety. At the same time, the sterilization device 40 is supported and fixed by the first partition structure 50, and there is no need to set up an additional support structure for the sterilization device 40, thereby reducing the number of parts in the mobile fresh-keeping equipment, reducing the processing cost and disassembly and assembly difficulty of the mobile fresh-keeping equipment, and making the structural layout in the cabinet 10 more reasonable and compact.

[0068] Specifically, a support beam is provided on the upper surface of the first partition structure 50 , and the sterilization device 40 is installed on the support beam to prevent the water buffered in the first partition structure 50 from contacting the sterilization device 40 and contaminating the sterilization device 40 .

[0069] Optionally, the sterilization device 40 is a plasma sterilization device.

[0070] like Figures 3 to 5 As shown, the mobile fresh-keeping device also includes a water collection structure 80. Located below the first partition structure 50, the water collection structure 80 collects the water flowing out of the humidifier 60. During operation, the water flowing out of the humidifier 60 is buffered by the water collection structure 80, thereby preventing the water from flowing into the cabinet 10 and causing spoilage.

[0071] In this embodiment, the water receiving structure 80 is located below the humidifier 60 .

[0072] Optionally, the water receiving structure 80 is a water receiving tray.

[0073] like Figure 3 As shown, the cabinet 10 includes a bent side panel 12, which includes a first plate 122 and a second plate 123 arranged at an angle, with the first plate 122 positioned above the second plate 123. The second partition structure 100 includes a first sub-partition 102, a second sub-partition 103, and a third sub-partition 104. The first sub-partition 102 and the second plate 123 are arranged opposite each other and surround each other to form at least a portion of the second circulation duct. The first sub-partition 102 has a second ventilation hole 1021, and the first airflow space is connected to the storage chamber 112 through the second ventilation hole 1021. The second sub-partition 103 is connected to the first sub-partition 102 and positioned above the first sub-partition 102. The first ventilation hole 101 is provided on the second sub-partition 103. The third sub-partition 104 is connected to the second sub-partition 103 and is located above the second sub-partition 103. The third sub-partition 104 is arranged opposite to the sterilization device 40 and has a third ventilation hole 1041. The storage cavity 112 is connected to the sterilization device 40 through the third ventilation hole 1041. In this way, the third sub-partition 104, the second sub-partition 103 and the first sub-partition 102 are arranged in sequence along the height direction of the cabinet 10. Each sub-partition is arranged opposite to the corresponding structure to isolate the corresponding structure and the storage cavity 112 while ensuring that the first installation cavity 111 can be connected to the storage cavity 112 for airflow. At the same time, the above arrangement makes the structure of the second partition structure 100 simpler, easier to process and implement, and reduces the processing cost and difficulty of the second partition structure 100.

[0074] Specifically, the second circulation air duct includes a first airflow space. The third sub-partition 104 is located between the sterilization device 40 and the storage chamber 112 to isolate the two, and communication between the sterilization device 40 and the storage chamber 112 is achieved through the third ventilation hole 1041. The second sub-partition 103 is located between the fan 70 and the storage chamber 112, and the fan 70 is located between the humidifier 60 and the second sub-partition 103. The air outlet of the fan 70 is connected to the storage chamber 112 through the first ventilation hole 101. The first sub-partition 102 is located between the second plate 123 and the storage chamber 112, and the first airflow space is formed between the first sub-partition 102 and the second plate 123. Gas in the storage chamber 112 can enter the first airflow space through the second ventilation hole 1021, and then enter the air inlet of the fan 70 through the first airflow space, forming a second circulation path.

[0075] In this embodiment, the first plate body 122 and the second plate body 123 are arranged perpendicular to each other, the first plate body 122 and the water receiving structure 80 are arranged opposite to each other and have a gap, the second plate body 123 and the first sub-partition 102 are arranged opposite to each other and form a first air flow space, and the first air flow space and the gap are connected to each other so that the air flow entering the first air flow space can flow back to the fan 70 through the gap to realize the circulation of the air flow in the cabinet body 10.

[0076] Optionally, the first sub-partition plate 102 and the second sub-partition plate 103 are connected by fasteners.

[0077] Optionally, the second sub-partition plate 103 and the third sub-partition plate 104 are connected by fasteners.

[0078] Optionally, the first partition structure 50 includes a bottom plate and a peripheral wall arranged on the bottom plate, the drain hole is located on the bottom plate, and the peripheral wall has an overflow hole, which is connected to the water buffer device. The peripheral wall is connected to the second sub-partition 103 and / or the third sub-partition 104, and the sterilization device 40 is arranged on the bottom plate. In this way, if the height of the condensed water cached in the first partition structure 50 reaches the height of the overflow hole, it can enter the water buffer device through the overflow hole to prevent the condensed water from overflowing from the first partition structure 50 into the cabinet 10 and causing bad results. At the same time, the above-mentioned arrangement makes the structure of the first partition structure 50 simpler, easier to process and realize, reduces the processing cost of the first partition structure 50, and also makes the connection relationship of the first partition structure 50 more flexible and diverse to meet different usage requirements and working conditions.

[0079] In this embodiment, the peripheral wall is connected to both the second sub-partition 103 and the third sub-partition 104, thereby preventing the peripheral wall from blocking the first ventilation hole 101 and the third ventilation hole 1041 and affecting the normal flow of air, thereby improving the flow smoothness of the gas in the cabinet 10.

[0080] In this embodiment, a portion of the outer peripheral wall of the first partition structure 50 is fitted with and connected to the inner wall of the cabinet body 11, and another portion of the outer peripheral wall of the first partition structure 50 is connected to the second sub-partition 103 and the third sub-partition 104, so as to separate the chambers on the upper and lower sides of the first partition structure 50 in the first installation cavity 111 into a first sub-chamber and a second sub-chamber that are independent of each other and non-connected. The first sub-chamber is located above the second sub-chamber, the sterilization device 40 and the air inlet and return air outlet of the refrigerator 20 are located in the first sub-chamber, and the humidifier 60 and the fan 70 are located in the second sub-chamber, so that the return air path of the refrigerator 20 and the return air path of the fan 70 are independent of each other and do not interfere with each other.

[0081] Optionally, the water receiving structure 80 is disposed on the first plate 122, the mobile fresh-keeping equipment further includes a support plate 140 disposed on the first plate 122, the fan 70 is disposed on the support plate 140, at least a portion of a second circulation air duct is formed between the water receiving structure 80, the support plate 140, and the first plate 122, and the humidifier 60 is disposed on the water receiving structure 80; and / or the humidifier 60 is a wet film humidifier. In this manner, the second circulation air duct includes a second air flow space, formed between the water receiving structure 80 and the first plate 122, and connected to the first air flow space. The second air flow space is connected to the air inlet of the fan 70. The above-described arrangement of the second air flow space ensures that the fan 70 can return air, thereby improving the flow smoothness of the second circulation path. Furthermore, this arrangement simplifies the structure of the humidifier 60, making it easier to manufacture and implement, thereby reducing the manufacturing cost and difficulty of the humidifier 60.

[0082] In this embodiment, the water receiving structure 80 and the fan 70 are both arranged on the first plate body 122, and a second wind flow space connected to the first wind flow space is formed between the water receiving structure 80 and the first plate body 122. The airflow entering the first wind flow space through the second ventilation hole 1021 flows back to the air inlet of the fan 70 through the second wind flow space, and enters the storage cavity 112 through the air outlet of the fan 70 and the first ventilation hole 101 to form a second circulation path.

[0083] In this embodiment, the humidifier 60 is a wet film humidifier. The condensed water discharged from the drainage hole of the first partition structure 50 is sprayed onto the wet film, and then the fan 70 starts the circulation and forms an air flow to drive the water droplets on the wet film into the storage chamber 112 to achieve the purpose of humidification.

[0084] Optionally, the air supply duct 30 is made of a flexible material and is provided with a hook mounted on the inner top surface of the cabinet 10; and / or, there is at least one air supply duct 30; and / or, there is at least one air outlet 31; and / or, an ozone reduction net 120 is provided between the air outlet of the fan 70 and the first ventilation hole 101. This configuration reduces the weight of the air supply duct 30, increases the air outlet efficiency and volume of the air supply duct 30, and thereby improves the cooling efficiency of the refrigerator 20. At the same time, the ozone reduction net 120 converts the gas within the cabinet 10 into fresh air, thereby better preserving the fresh fruits and vegetables to be preserved.

[0085] Optionally, when there are multiple air supply ducts 30 , the multiple air supply ducts 30 are arranged at intervals along the width direction of the cabinet 10 .

[0086] Optionally, when there are multiple air outlet portions 31 , the multiple air outlet portions 31 are arranged at intervals along the length direction and / or circumferential direction of the air supply duct 30 .

[0087] In this embodiment, the air supply duct 30 is a bag-type air supply tube. When the refrigerator 20 is started, the cold air from the refrigerator 20 expands the bag-type air supply tube to release air. Furthermore, the air supply duct 30 is hung on the inner top surface of the cabinet 10 by a hook, which reduces the difficulty of disassembly and installation of the air supply duct 30 without affecting its expansion or contraction.

[0088] In this embodiment, there are four air supply ducts 30, which are arranged at intervals along the width direction of the cabinet 10. Each air supply duct 30 extends along the length direction of the cabinet 10, thereby increasing the air supply volume of the air supply duct 30 and improving the air supply efficiency.

[0089] It should be noted that the number of air supply ducts 30 is not limited thereto and can be adjusted according to working conditions and usage requirements.

[0090] Optionally, there are two, three, five, or more air supply ducts 30.

[0091] like Figures 1 to 4As shown, the refrigeration assembly also includes a condenser 90 connected to the refrigerator 20. The cabinet 10 includes a cabinet body 11 and a grille 13. The refrigerator 20 is located within the cabinet body 11. The cabinet body 11 has a first mounting cavity 111, a storage cavity 112, and a bent side panel 12. The bent side panel 12 protrudes inward from the cabinet body 11, forming a mounting recess. The grille 13 wraps around the cabinet body 11 and, between the grille 13 and the mounting recess, forms a second mounting cavity 121. The condenser 90 is disposed within the second mounting cavity 121. The refrigerator 20 is located above the condenser 90. This arrangement makes the condenser 90 an outdoor unit relative to the refrigerator 20, while the refrigerator 20 is an indoor unit relative to the condenser 90. The condenser 90 and refrigerator 20 operate in conjunction to ensure that the refrigerator 20 can blow out cool air. The grille 13 protects the condenser 90 while dissipating heat from it.

[0092] Specifically, an installation recess is formed on the outer surface of the cabinet body 11, and the grille 13 is arranged around the installation recess and a second installation cavity 121 for installing the condenser 90 is formed between the grille 13 and the installation recess, so that the appearance of the cabinet 10 is more regular and beautiful, thereby enhancing the user's visual experience.

[0093] Optionally, the cabinet body 11 is formed by surrounding a foam board.

[0094] In this embodiment, the cabinet body 10 is a rectangular parallelepiped, and the mounting recess is located on one side of a short side of the cabinet body 10 .

[0097] In this embodiment, the mobile fresh-keeping equipment has a fresh-keeping mode, a standby mode, a humidification mode, and a general mode. The mobile fresh-keeping equipment also includes a control module, which is connected to the condenser 90, the refrigerator 20, the fan 70, and the humidifier 60. When the mobile fresh-keeping equipment is in the fresh-keeping mode, the control module controls the condenser 90 and the refrigerator 20 to be in the on state. When the mobile fresh-keeping equipment is in the standby mode, the control module controls the condenser 90 and the refrigerator 20 to be in the off state. When the mobile fresh-keeping equipment is in the humidification mode, the control module controls the fan 70 and the humidifier 60 to be in the on state. When the mobile fresh-keeping equipment is in the general mode, the control module controls the humidifier 60 to be in the off state. In this way, the above-mentioned setting enables the mobile fresh-keeping equipment to have four operating modes, and adopts corresponding operating modes for different humidity and temperature, thereby improving the versatility and applicability of the mobile fresh-keeping equipment to meet different usage needs and working conditions, and also improving the user experience.

[0098] In this embodiment, the humidity in the mobile fresh-keeping equipment is maintained at about 90%, which increases the storage humidity of fruits and vegetables and reduces dryness loss.

[0099] In this embodiment, a sterilizer 40 sterilizes the cabinet 10 and the fruits and vegetables to be preserved. Return air from the refrigerator 20 passes through the sterilizer 40, destroying bacteria in the air and simultaneously ionizing it to produce active radicals such as hydroxyl groups that kill bacteria. If the ozone concentration in the cabinet 10 is too high, the fan 70 is turned on, and the ozone passes through the ozone reduction network 120 at the air outlet of the fan 70, accelerating its decomposition.

[0100] like Figures 1 to 4 As shown, the bottom of the cabinet 10 is provided with supporting legs 130 to support the cabinet 10 .

The humidity sensor, located at the refrigerator's return air inlet (or air inlet), controls the humidification system to adjust humidity. When the humidity at the refrigerator's return air inlet (or air inlet) is s≤S2, the fan 70 and humidifier 60 are turned on to begin humidification.

[0144] In some embodiments, when making the goods stay in the buffer cavity 113 for precooling first, if T slow temperature ≤ T open + △T1, open the partition door 151 and then move the goods to the storage cavity 112, where T slow temperature is the temperature of the buffer cavity 113, T open is the first preset partition door opening temperature, and △T1 is the allowable first temperature deviation value; and / or when making the goods move from the storage cavity 112 to the buffer cavity 113 to stay first, if T cold temperature ≥ T open + △T2, close the partition door 151, and if T cold temperature ≤ T stop, open the partition door 151 again.

[0146] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:

[0147] The mobile fresh-keeping equipment includes a cabinet, a refrigeration assembly, an air supply duct, and a fan. The cabinet has a first circulation air duct and a second circulation air duct, with the first circulation air duct located above the second circulation air duct. The refrigeration assembly includes a refrigerator located within the first circulation air duct. The air supply duct is disposed within the cabinet and has an air inlet and an air outlet. The air inlet is connected to at least part of the air outlet of the refrigerator. Cold air blown out from the refrigerator passes through the air inlet and the air outlet in sequence before entering the first circulation air duct. The fan is disposed within the second circulation air duct and below the refrigerator. In this way, the cold air generated by the refrigerator first enters the air inlet of the air supply duct, is then discharged into the cabinet through the air outlet of the air supply duct, and then blows the cold air onto the fruits and vegetables to be preserved stored in the cabinet to cool them and preserve them. After completing the cooling and preservation process, the airflow reenters the refrigerator, allowing the airflow to flow within the first circulation air duct and forming a first circulation path between the refrigerator, the air supply duct, and the cabinet. The air inlet and outlet of the fan are both located below the refrigerator. The air flow blown out from the air outlet of the fan can flow back to the air inlet of the fan after passing through the fruits and vegetables to be preserved, so that the air flow flows in the second circulation duct and forms a second circulation path between the fan and the cabinet. The second circulation path is located below the first circulation path and disturbs the gas located below the cabinet to make the cold air in the cabinet more uniform, thereby realizing full-area penetration air supply in the cabinet, avoiding cold air directly blowing on the surface of the fruits and vegetables to be preserved, and sending cold air to every corner of the cabinet, and the air supply is uniform, reducing the surface dryness of the fruits and vegetables to be preserved and reducing water loss, thereby solving the problem of poor preservation performance of mobile cold storage equipment in the existing technology and improving the storage rate of good fruits.
