DETAILED DESCRIPTION

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] One of the core concepts of the embodiment of the present invention is to store water by adding a water storage component and clean the evaporator through the water spraying device in the water storage component in the cleaning mode, which not only prevents the evaporator pipeline from corrosion caused by moisture and impurities, but also ensures the efficient heat exchange performance of the evaporator, thereby continuously optimizing the refrigeration effect, extending the service life of the equipment, and improving the overall operating efficiency and reliability.

[0045] Reference Figure 1 , shows a structural block diagram of a refrigeration device provided by an embodiment of the present invention.

[0046] The refrigeration equipment 11 includes: an evaporation component 101 deployed in the cold storage, the evaporation component includes an evaporator 1011; a condensation component 102 and a water storage component 103 deployed outside the cold storage; the water storage component 103 includes a water sprinkling device 1031, and the position of the water sprinkling device 1031 corresponds to the evaporator 1011; the water storage component 103 is used to store water generated during the heat exchange of the condensation component 102, and after the refrigeration equipment 11 starts the cleaning mode, water is sprayed on the evaporator 1011 through the water sprinkling device 1032 to clean the evaporator 1011.

[0047] Reference Figure 2 , showing a structural diagram of a refrigeration device provided by an embodiment of the present invention,

[0048] The evaporator 1011 uses an optimized heat exchange tube and fin structure, which significantly improves the heat exchange efficiency. These heat exchange tubes are usually made of high thermal conductivity materials (such as copper or aluminum alloy), which can quickly absorb the heat in the air in the cold storage, allowing the refrigerant to evaporate quickly and take away the heat, thereby achieving efficient cooling. In addition, the design of the fins increases the surface area, further improving the heat exchange efficiency and ensuring that the cold air can be evenly distributed throughout the cold storage space. Modern evaporators 1011 are usually equipped with advanced sensors and control systems that can monitor key parameters such as temperature, humidity and frost thickness in real time. Through intelligent control logic, the system can automatically start the defrost program when necessary to ensure that the evaporator is always in the best working condition. In addition, some models also integrate a self-cleaning function, using a water spray device to clean the surface of the evaporator to prevent dust and dirt from accumulating and reduce the need for manual maintenance. Although the structure of the top-mounted unit makes manual cleaning difficult, the introduction of the automation system greatly simplifies the maintenance process and improves work efficiency. The temperature inside the cold storage is usually low, and the evaporator 1011 must be able to operate reliably under extremely low temperature conditions. To this end, the evaporator adopts a special sealing and insulation design to ensure that condensed water will not freeze or cold bridge will not occur in low temperature environments, affecting the heat exchange efficiency. At the same time, the fan and motor of the evaporator are also specially designed to maintain stable performance in low temperature environments, avoiding mechanical failures or electrical problems caused by low temperatures.

[0049] In addition, in order to reduce energy consumption, the evaporator 1011 can be equipped with an efficient compressor and expansion valve to ensure that energy loss during the refrigerant cycle is minimized. In addition, frequency conversion technology and intelligent control systems can adjust the cooling capacity according to actual needs to avoid unnecessary energy waste. This energy-saving design not only reduces operating costs, but also meets the requirements of modern cold storage for environmental protection and sustainable development. Some models also use environmentally friendly refrigerants to reduce the damage to the ozone layer and greenhouse gas emissions. Although the evaporator 1011 has a complex internal structure and high performance, its design is very compact and suitable for installation in limited spaces. Especially in top-mounted units, the evaporator is usually located on the top of the cold storage and does not occupy valuable ground space. At the same time, the modular design allows the evaporator to be flexibly combined to meet the needs of different cold storage sizes and layouts. This compact and flexible installation method not only improves space utilization, but also simplifies the installation and commissioning process.

[0050] The evaporation assembly 11 also includes an evaporation fan 1012, the primary task of which is to enhance the air flow on the surface of the evaporator 1011 through forced convection, thereby improving the heat exchange efficiency. During the refrigeration process, the low-temperature and low-pressure refrigerant absorbs the heat of the surrounding air in the evaporator and evaporates into gas. The evaporation fan accelerates the heat transfer process by sucking in the warm air in the cold storage and blowing it over the fin surface of the evaporator. This forced convection method significantly increases the contact time and area between the air and the evaporator surface, allowing the refrigerant to absorb heat more quickly and achieve an efficient refrigeration effect. In order to ensure the uniformity of the temperature in the cold storage, the evaporation fan 1012 is also responsible for evenly distributing the cooled air in the cold storage space. Through reasonable air duct design and fan position layout, the evaporation fan can deliver cold air to every corner to avoid excessive local temperature differences. This is particularly important for storing temperature-sensitive foods, such as fruits, vegetables, and frozen meat. Uniform cold air distribution not only improves the refrigeration effect, but also extends the shelf life of food and reduces the risk of food deterioration due to uneven temperature.

[0051] In addition, in addition to the evaporator 1011 and the evaporation fan 1012, the evaporation component 11 may also include a plurality of auxiliary and control components to ensure its efficient, reliable and intelligent operation. These additional components work together to optimize the overall performance of the evaporation component and improve the refrigeration effect and maintenance convenience of the cold storage. Specifically, it may include auxiliary and control components such as temperature sensors, defrost controllers, filters, and control panels. These components work together to ensure the efficient operation and long-term reliability of the evaporation component and improve the refrigeration effect and maintenance convenience of the cold storage. By integrating multiple functions and technologies, the evaporation component provides users with a more intelligent and reliable refrigeration solution, meeting the needs of modern cold storage for efficiency, energy saving and environmental protection.

[0052] The condensing fan 1021 accelerates heat transfer by sucking in outside air and blowing it across the fin surface of the condenser. This forced convection method significantly increases the heat exchange rate between the air and the condenser surface, allowing the high-temperature and high-pressure gaseous refrigerant to release heat and condense into liquid more quickly. Through continuous air flow, the condensing fan maintains the temperature difference between the condenser surface and the surrounding air, ensuring the continuity and efficiency of the condensation process. If there is no forced convection provided by the fan, and only natural convection is relied on, the condensation efficiency will be greatly reduced, resulting in a decrease in system performance. Condensing fans usually use variable frequency technology, which can automatically adjust the speed according to the ambient temperature and system requirements. In a high temperature environment, the fan can increase the speed to increase the heat dissipation effect; in a low temperature environment, the speed can be reduced to save energy. This intelligent control not only improves the response speed of the system, but also optimizes the energy efficiency ratio.

[0053] The condenser 1022 flows with high-temperature and high-pressure gaseous refrigerant inside, while the outside exchanges heat with the outside air through fins. The material of the condenser is usually copper or aluminum alloy with good thermal conductivity to ensure efficient heat conduction. The fin structure increases the surface area and further improves the heat exchange efficiency. When the high-temperature and high-pressure gaseous refrigerant enters the condenser, it transfers heat to the surrounding air through the tube wall, and its own temperature gradually decreases and condenses into a liquid state. In this process, the refrigerant releases a large amount of latent heat, causing the temperature to drop rapidly, and finally completing the transition from gas to liquid. The condenser plays a certain role in pressure regulation during the condensation process. As the refrigerant condenses, the pressure in the system gradually balances, avoiding damage to the compressor and other components caused by excessive pressure. At the same time, the condenser is also connected to the evaporator through a throttling device (such as an expansion valve) to ensure the smooth conversion of the refrigerant in different states. Since the external environment of the cold storage may be relatively harsh, the condenser usually adopts an anti-corrosion coating or stainless steel material to prevent corrosion problems caused by long-term exposure to the outside. In addition, the sealing design of the condenser also ensures that the refrigerant will not leak, ensuring the safety and reliability of the system.

[0054] The condensing fan 1021 and the condenser 1022 work together during the condensation process to ensure the efficient operation of the refrigeration system. The condensing fan provides the necessary air flow and enhances the heat dissipation effect of the condenser; while the condenser realizes the transformation of the refrigerant from gas to liquid through efficient heat exchange. The two complement each other and are indispensable to ensure the stability and energy efficiency of the entire refrigeration system.

[0055] In addition to the condensing fan 1021 and the condenser 1022, the condensing assembly 102 may also include temperature and pressure sensors, cooling water systems, anti-corrosion coatings and sealing designs, intelligent controllers, filters, protective covers and other auxiliary and control components. These components together improve the performance, reliability and intelligence level of the condensing assembly, ensure the efficient operation of the condensing process, and optimize the energy efficiency of the entire refrigeration system. By integrating multiple functions and technologies, the condensing assembly provides users with a more intelligent and reliable refrigeration solution, meeting the needs of modern cold storage for high efficiency, energy saving and environmental protection.

[0056] The water storage component 103 is an important auxiliary device in the refrigeration system. Its main function is to store the water generated during the heat exchange process of the condensing component 102, and to clean the evaporator 1011 through the water spraying device 1031 in the cleaning mode. The position of the water spraying device 1031 corresponds to the evaporator 1011 to ensure that the water spraying can evenly cover the entire surface of the evaporator. This design not only improves the cleaning effect, but also reduces the waste of water resources. The water spraying device is usually composed of multiple nozzles, and the angle and flow rate of each nozzle are carefully designed to achieve the best spraying effect. The nozzle material is made of corrosion-resistant materials, such as stainless steel or engineering plastics, to ensure that it will not age or be damaged during long-term use. After the refrigeration equipment 11 turns on the cleaning mode, the water in the water storage component 103 is sprayed onto the surface of the evaporator 1011 through the water spraying device 1031 to clean it. This cleaning method can not only remove dust, dirt and microorganisms on the surface of the evaporator, but also prevent the heat exchange efficiency from decreasing due to long-term accumulation. Especially for corrosive substances that may exist in the cold storage environment (such as acidic components in sauerkraut), regular cleaning can effectively protect the evaporator copper tubes and extend the life of the equipment.

[0057] Due to the special environment of the cold storage, the evaporator 1011 may come into contact with corrosive food or harmful substances in the air. The design of the water storage component 103 and the water sprinkling device 1031 fully considers this and adopts a variety of anti-corrosion measures. For example, the inside of the water storage component is coated with an anti-corrosion coating to prevent rust caused by long-term contact with water; the nozzle of the water sprinkling device is made of corrosion-resistant materials to ensure that it will not be damaged during long-term use. In addition, the system can also add appropriate preservatives to further enhance the anti-corrosion effect. The design of the water storage component 103 focuses on environmental protection and reduces the demand for fresh water resources by recycling condensed water. This water-saving design not only reduces operating costs, but also conforms to modern environmental protection concepts. At the same time, the system is equipped with a water quality monitoring device to ensure that the discharged water meets environmental protection standards and does not pollute the surrounding environment. Traditional evaporator cleaning usually requires manual intervention, which is time-consuming and labor-intensive and easy to miss details. The automatic cleaning function of the water storage component 103 greatly simplifies the maintenance process and reduces downtime and labor costs. Especially in overhead units, the problem of difficult manual cleaning has been effectively solved, further improving the reliability and availability of the system. With the rapid development of cold chain logistics and food processing industries, cold storage is increasingly being used. The innovative design of the water storage component 103 and the water sprinkling device 1031 provides a more efficient, reliable and environmentally friendly solution for the cold storage refrigeration system. In the future, this technology is expected to be promoted and applied in more fields, providing better protection and support for various refrigeration facilities.

[0058] Reference Figure 3 , showing a partially enlarged structural diagram of a refrigeration device provided by an embodiment of the present invention.

[0059] In one embodiment, the water storage component 103 also includes: a water tank 1032, a water level sensing device 1033 and a water pipe 1034; the water storage component 103 is used to transfer the water in the water tank 1032 to the water sprinkling device 1031 through the water pipe 1034 to clean the evaporator 1011 when the preset cleaning conditions are met; the preset cleaning conditions are: the water level sensing device 1033 detects that the water level information of the water tank 103 reaches the preset water level, and the time since the last cleaning of the evaporator 1011 is greater than the preset cleaning cycle.

[0060] The water storage tank 1032 is the core storage unit of the entire water storage component, which is used to collect and store the water generated by the condensing component 102 during the heat exchange process. The water storage tank 1032 is equipped with an anti-overflow design to prevent leakage accidents caused by excessive water. The water level sensor 1033 monitors the water level in the water storage tank 1032 in real time and can feed back the data to the control system. When the water level reaches the preset upper limit, the system will automatically start the drainage pump or prompt the user to perform drainage operations to ensure that the water storage tank is not overfilled. The water guide pipe 1034 is a transmission channel connecting the water storage tank 1032 and the water sprinkling device 1031, which is responsible for guiding the water in the water storage tank to the water sprinkling device. In order to achieve precise control, a switch is also provided in the water guide pipe. When the preset cleaning conditions are met, the control system will automatically turn on this switch to allow water to flow through the water guide pipe and be transmitted to the water sprinkling device. This design not only improves the utilization rate of water resources, but also ensures the controllability and efficiency of the cleaning process.

[0061] The water level sensing device 1033 detects that the water level of the water storage tank 1032 has reached the preset value. This condition ensures that there is enough water in the water storage tank for cleaning during cleaning. If the water level is insufficient, the cleaning effect will be greatly reduced, and even the entire cleaning process cannot be completed. The time since the last cleaning of the evaporator 1011 is greater than the preset cleaning cycle. This condition prevents the cleaning from being too frequent, avoiding unnecessary waste of water resources and equipment wear. Frequent cleaning not only increases energy consumption, but also may cause excessive wetting of the evaporator surface, increasing the risk of frost. By setting a reasonable cleaning cycle, the system can clean according to actual needs, ensuring that the evaporator always maintains good heat exchange performance, while reducing the burden on the environment and resources. Combining these two conditions, the system can achieve dual optimization of water resources and cleaning frequency. When the water level reaches the preset value, it means that the condensation component 102 has generated enough condensed water, which can be reused for evaporator cleaning, realizing the effective recycling of water resources. The preset cleaning cycle ensures that the cleaning operation will not be too frequent, which not only ensures the cleanliness of the evaporator, but also avoids waste of resources.

[0062] When the preset cleaning conditions are met, the control system will confirm that there is enough water in the water storage tank 1032 based on the data provided by the water level sensing device 1033. The evaporator 1011 will be defrosted. After the defrosting is completed, the evaporation component 101 and the condensation component 102 will be turned off. Then the control system will turn on the switch in the water pipe 1034 to allow water to flow through the water pipe and be transmitted to the water spraying device 1031. The water spraying device sprays water evenly onto the surface of the evaporator 1011 to complete the cleaning process. After the cleaning is completed, the system will turn off the switch, stop the water supply, and condense the fan 1022 as needed to help the surface of the evaporator dry quickly to ensure that it returns to normal operation.

[0063] Reference Figure 4, shows another partially enlarged structural diagram of a refrigeration device provided by an embodiment of the present invention.

[0064] In one embodiment, it also includes: an air guide component 104 connecting the inside and outside of the cold storage; the inner wall of the cold storage includes a fresh air outlet 105; the condensing component 102 is used to stop running after the refrigeration device 11 starts the cleaning mode until the evaporator 1011 is cleaned; after the evaporator 1011 is cleaned, start running, absorb outdoor air, and transmit the hot air generated by heat exchange with the air to the air guide component 104, and transmit the hot air to the inside of the cold storage through the air guide component 104 to dry the water after cleaning;

[0065] The air in the cold storage is transmitted to the outside of the cold storage through the fresh air outlet.

[0066] When the refrigeration equipment 11 enters the cleaning mode, the condensation component 102 and other related components will temporarily stop running. This is to ensure that no new condensed water will be generated during the cleaning process or affect the cleaning effect. During the shutdown period, the evaporation fan 1012 will also stop working to prevent cold air from interfering with the cleaning process. This shutdown arrangement ensures that the cleaning operation can be carried out under optimal conditions and prevents incomplete cleaning due to equipment operation. In the cleaning mode, the water spraying device 1031 of the water storage component 103 sprays the water in the water storage tank 1032 evenly onto the surface of the evaporator 1011 through the water guide pipe 1034 to clean it. This process can remove dust, dirt and microorganisms on the surface of the evaporator to prevent long-term accumulation from affecting the heat exchange efficiency. In particular, for possible corrosive substances (such as acidic components in sauerkraut), regular cleaning can also effectively protect the evaporator copper tube and extend the life of the equipment. After the cleaning is completed, the condensation component 102 restarts and enters normal operation. At this time, the main task of the condensation component is to absorb outdoor air, generate hot air through heat exchange and pass it into the cold storage to ensure the dryness and safety of the environment in the cold storage. In addition, the fresh air vent 105 on the inner wall of the cold storage is an important part of the air guide assembly 104, which is responsible for introducing fresh air and exhausting moisture. This design not only improves the cleaning efficiency, but also optimizes the air quality in the cold storage, prolongs the life of the equipment, and ensures the safety and quality of food storage.

[0067] Reference Figure 5 , shows another partially enlarged structural diagram of a refrigeration device provided by an embodiment of the present invention.

[0068] In one embodiment, the condensing component 102 is used to absorb outdoor air after the refrigeration device 11 turns on the refrigeration mode, and transmit the hot air generated by heat exchange with the air to the air guide component 104, and transmit the hot air to the outside of the cold storage through the air guide component 104;

[0069] In the cooling mode, the main task of the condensing component 102 is to cool and condense the high-temperature and high-pressure gaseous refrigerant into a liquid state. In order to achieve this goal, the condensing component needs a large amount of outside air to take away the heat in the refrigerant. Therefore, the condensing component is equipped with an efficient fan system that can quickly absorb outdoor air and guide it to the surface of the condenser 1022 for heat exchange. When the outdoor air passes through the condenser 1022, the high-temperature and high-pressure gaseous refrigerant flows inside the condenser. These refrigerants transfer heat to the inhaled air during the heat exchange process, causing the air temperature to rise rapidly and form hot air. This process not only effectively reduces the temperature of the refrigerant, causing it to condense into a liquid state, but also ensures the efficient operation of the condensing component. If the generated hot air is not discharged in time, it may have an adverse effect on the temperature in the cold storage. Therefore, the refrigeration equipment 11 designs a special path to transmit the hot air to the outside of the cold storage through the air guide component 104. The air guide component usually includes an air duct, a pipe and an air outlet to ensure that the hot air can be quickly and smoothly discharged from the cold storage to prevent heat from flowing back into the cold storage.

[0070] The air guide assembly 104 is designed with special air ducts and pipes to ensure that the hot air can be quickly and smoothly transmitted from the condensing assembly to the outside of the cold storage. These air ducts are usually made of high temperature resistant materials to withstand the high temperature environment of the hot air. Through the air outlet of the air guide assembly located outside the cold storage, it is ensured that the hot air is directly discharged into the external environment without interfering with the temperature inside the cold storage. This not only improves the refrigeration effect, but also maintains the temperature stability in the cold storage.

[0071] The evaporation component 101 is used to absorb indoor air after the refrigeration device turns on the refrigeration mode, and transmit the cold air generated by heat exchange with the air to the air guide component 104, and transmit the cold air to the inside of the cold storage through the air guide component 104.

[0072] In the cooling mode, the main task of the evaporation component 101 is to absorb the warm air in the cold storage, and to perform heat exchange through the evaporator 1011, and to transfer the heat in the air to the low-temperature and low-pressure refrigerant, so that it evaporates into gas. In order to achieve this goal, the evaporation component is equipped with an efficient evaporation fan 1012, which can quickly absorb the air in the cold storage and guide it to the surface of the evaporator for cooling. When the warm air in the cold storage passes through the evaporator 1011, the refrigerant with low temperature and low pressure flows inside the evaporator. These refrigerants absorb heat from the air and evaporate during the heat exchange process, so that the air temperature drops rapidly and forms cold wind. This process not only effectively reduces the air temperature, but also ensures the efficient operation of the evaporation component and provides a continuous cooling effect. If the generated cold air is not transmitted back to the cold storage in time, it may cause local uneven temperature or reduced refrigeration efficiency. Therefore, the refrigeration equipment 11 designs a special path to transmit the cold air to the cold storage through the air leakage port of the air guide component 104 located inside the cold storage. And at this time, the new air outlet 105 is closed to ensure that the cold air can quickly and smoothly cover every corner of the cold storage.

[0073] Reference Figure 6 , shows another partially enlarged structural diagram of a refrigeration device provided by an embodiment of the present invention.

[0074] In one embodiment, the air guide component 104 includes: an air guide duct, the air inlet of the air guide duct is connected to the condensation component, and the air outlet of the air guide duct corresponds to the position of the evaporator 1011.

[0075] In the cleaning mode, the condensing component 102 absorbs outdoor air and performs heat exchange, and the generated hot air is transmitted to the inside of the cold storage through the air duct. The design of the air duct ensures that the hot air can be quickly and smoothly transmitted from the condensing component to the designated location to avoid heat loss. This efficient transmission path allows the hot air to be blown directly to the evaporator 1011, helping to quickly dry the residual moisture after cleaning, ensuring that the surface of the evaporator is dry, and preventing frost or moisture problems. The design of the air duct not only takes into account functional requirements, but also optimizes space utilization. The air duct can be flexibly arranged according to the specific layout of the cold storage to ensure that it does not take up too much space while covering the evaporator 1011 in the cold storage. This compact and flexible installation method not only improves space utilization, but also simplifies the installation and commissioning process and improves construction efficiency.

[0076] In one embodiment, the air guide duct includes a first duct 1041, a second duct 1042 and a third duct 1043; the first duct 1041 is horizontally arranged and located outside the cold storage; the second duct 1042 is horizontally arranged and located inside the cold storage; the third duct 1043 is vertically arranged and connects the first duct 1041 and the second duct 1042.

[0077] Through the connection of the first pipe 1041, the second pipe 1042 and the third pipe 1043, the hot air generated by the condensing component can be transmitted to the outside or inside of the cold storage according to the demand, which not only realizes the effective transmission and precise distribution of hot and cold air, but also optimizes the space utilization and installation flexibility. The first pipe 1041 ensures that the hot air will not flow back into the cold storage during refrigeration, the second pipe 1042 provides uniform cold air distribution, and the third pipe 1043 plays a key connection and transition role. This design not only improves the overall efficiency of the system, but also ensures the stability and safety of the environment in the cold storage, providing users with a more intelligent and reliable refrigeration solution, meeting the needs of modern cold storage for high efficiency, energy saving and environmental protection.

[0078] In one embodiment, one end of the first duct 1041 is the air inlet of the air guide duct (not shown in the figure), and the other end is provided with a first air leakage port (not shown in the figure) and a first baffle (not shown in the figure) located at the first air leakage port; a second air leakage port (not shown in the figure) is provided on the bottom wall of the second duct 1042, and a second baffle (not shown in the figure) is located at the second air leakage port; a third baffle 1044 is provided at the junction of the first duct 1041 and the third duct 1043; a fourth baffle 1045 is provided in the third duct 1043 at a position corresponding to the top wall of the cold storage;

[0079] One end of the first pipe 1041 is the air inlet of the air guide pipe, and the other end is provided with a first air leakage port and a first baffle located at the first air leakage port, so as to output the hot air output by the condensing component 102 from the first air leakage port to the outside of the cold storage by controlling the closing of the first baffle. A second air leakage port is provided on the bottom wall of the second pipe 1042, and a second baffle is located at the second air leakage port. The second air leakage port is provided with a plurality of small holes. By providing the second air leakage port on the bottom wall of the second pipe 1042, the cold air generated by the evaporation component 101 can be transmitted to the inside of the cold storage through the plurality of small holes of the second air leakage port. By providing the second baffle located at the second air leakage port, the second air leakage port can be shielded by the second baffle after the evaporator 1011 is cleaned so that the hot air generated by the condensing fan 1021 can dry the evaporator 1011 through the air outlet. The third baffle 1044 is provided at the junction of the first duct 1041 and the third duct 1043 to control the flow direction of the hot air generated by the condensing component 102. When the first baffle closes the first air leak, the third baffle 1044 is opened to make the air guide duct unobstructed, and the hot air generated by the condensing component 102 can pass through the third duct. The fourth baffle 1045 is provided at a position corresponding to the top wall of the cold storage in the third duct 1043 to separate the inner and outer parts of the cold storage in the duct. The fourth baffle 1045 is opened to make the air guide duct unobstructed, and the hot air generated by the condensing component 102 can pass through the third duct and then through the second duct to the evaporator 1011.

[0082] After the evaporator 1011 is cleaned, the first baffle is controlled by the first control module 1071 to close the first air leakage port, and the third baffle 1044 is controlled to open the air duct; the second baffle is controlled by the second control module 1072 to close the second air leakage port, and the fourth baffle 1045 is controlled by the third control module 1073 to open the air duct, so that the hot air output by the condensation component 102 is transmitted from the air outlet of the air duct to the evaporator 1011.

[0083] After the evaporator 1011 is cleaned, the first control module 1071 controls the first baffle to close the first air leak, and the third baffle 1044 is turned on to connect the air duct; at the same time, the second control module 1072 controls the second baffle to close the second air leak, and the third control module 1073 controls the fourth baffle 1045 to connect the air duct, ensuring that the hot air output by the condensing component 102 can be transmitted from the air outlet of the air duct to the evaporator 1011. This design ensures that the evaporator is quickly dried after cleaning to prevent frost or corrosion caused by residual moisture.

[0084] In one embodiment, the baffle control module 107 is used to control the first baffle to open the first air leakage port, control the second baffle to open the second air leakage port, and control the third baffle 1044 and the fourth baffle 1045 to block the air duct after the refrigeration equipment 11 turns on the refrigeration mode, so that the hot air output by the condensation component 102 is transmitted from the first air leakage port to the outside of the cold storage, and the cold air output by the evaporation component 101 is transmitted from the second air leakage port to the inside of the cold storage.

[0085] After the refrigeration device 11 turns on the refrigeration mode, the first control module 1071 controls the first baffle to open the first air leakage port, controls the third baffle 1044 to block the air duct, the second control module 1072 controls the second baffle to open the second air leakage port, and the third control module 1073 controls the fourth baffle 1045 to block the air duct, so that the hot air output by the condensation component 102 is transmitted from the first air leakage port to the outside of the cold storage, and the cold air output by the evaporation component 101 is transmitted from the second air leakage port to the inside of the cold storage.

[0086] After the refrigeration device 11 turns on the refrigeration mode, the first control module 1071 controls the first baffle to open the first air leakage port and block the air duct, so that the hot air output by the condensing component 102 is transmitted to the outside of the cold storage from the first air leakage port; at the same time, the second control module 1072 controls the second baffle to open the second air leakage port, and the third control module 1073 controls the fourth baffle 1045 to block the air duct, so that the cold air output by the evaporation component 101 is transmitted to the inside of the cold storage from the second air leakage port. This design optimizes heat management and refrigeration effects, ensures the stability and safety of the environment in the cold storage, and realizes an efficient and reliable refrigeration process.

[0087] In one embodiment, the evaporation assembly 101 is located at the top of the inner side of the cold storage;

[0088] The condensation component 102 and the water storage component 103 are located at the bottom outside the cold storage.

[0089] The evaporation component 101 is located at the top of the inside of the cold storage, and the condensation component 102 and the water storage component 103 are located at the bottom of the outside of the cold storage. This layout design is to optimize space utilization, improve system efficiency and ensure safe operation. Through reasonable space allocation and functional zoning, the system achieves efficient cold air distribution, avoids heat interference, facilitates maintenance and management, and protects equipment and cold storage environment, thus providing a stable and reliable refrigeration solution.

[0091] The water receiving tray 106 is located at the bottom of the evaporator 1011 and corresponds to the water sprinkling device 1031, and is used to collect the water generated during the cleaning of the evaporator 1011. This design ensures that the water generated during the cleaning process will not overflow or accumulate inside the cold storage, keeping the environment dry and tidy. The setting of the water receiving tray not only prevents the ground from being slippery and reduces safety hazards, but also prevents water from penetrating into the cold storage structure to prevent corrosion and damage. In addition, the position of the water receiving tray corresponds to that of the water sprinkling device, ensuring that all sprayed water can be effectively collected, thereby improving the utilization rate of water resources. By centrally collecting the water after cleaning, the system can further process or discharge the water, which meets environmental protection requirements, simplifies maintenance work, and ensures the stability and safety of the environment in the cold storage.
