Detailed Implementation

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] One of the core concepts of this invention is that by adding a water storage component to store water and cleaning the evaporator through a water spray device in the water storage component in cleaning mode, not only is corrosion of the evaporator pipes caused by moisture and impurities prevented, but also the high-efficiency heat exchange performance of the evaporator is ensured, thereby continuously optimizing the cooling effect, extending the service life of the equipment, and improving the overall operating efficiency and reliability.

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

[0046] The refrigeration equipment 11 includes: an evaporation assembly 101 deployed inside the cold storage, the evaporation assembly including an evaporator 1011; a condensation assembly 102 and a water storage assembly 103 deployed outside the cold storage; the water storage assembly 103 includes a water spraying device 1031, the position of which corresponds to the evaporator 1011; the water storage assembly 103 is used to store the water generated during the heat exchange process of the condensation assembly 102, and to spray water onto the evaporator 1011 through the water spraying device 1032 to clean the evaporator 1011 after the refrigeration equipment 11 is turned on in cleaning mode.

[0047] Reference Figure 2 The diagram shows a structural diagram of a refrigeration device provided in an embodiment of the present invention.

[0048] The 1011 evaporator employs an optimized heat exchange tube and fin structure, significantly improving heat exchange efficiency. These heat exchange tubes, typically made of highly thermally conductive materials (such as copper or aluminum alloys), rapidly absorb heat from the air inside the cold storage, causing the refrigerant to evaporate quickly and carry away the heat, thus achieving highly efficient cooling. Furthermore, the fin design increases the surface area, further enhancing heat exchange efficiency and ensuring that cold air is evenly distributed throughout the cold storage space. Modern 1011 evaporators are typically equipped with advanced sensors and control systems that monitor key parameters such as temperature, humidity, and frost thickness in real time. Through intelligent control logic, the system can automatically initiate the defrosting process when needed, ensuring the evaporator is always in optimal operating condition. In addition, some models integrate a self-cleaning function, using a water spray device to clean the evaporator surface, preventing dust and dirt accumulation and reducing the need for manual maintenance. While the overhead unit structure makes manual cleaning difficult, the introduction of automation systems greatly simplifies the maintenance process and improves work efficiency. The internal temperature of cold storage is typically low, requiring the 1011 evaporator to operate reliably under extreme low-temperature conditions. To address this, the evaporator employs a special sealing and insulation design to ensure that condensate does not freeze or cause cold bridging in low-temperature environments, thus preventing any impact on heat exchange efficiency. Simultaneously, the evaporator's fan and motor are also specially designed to maintain stable performance in low-temperature environments, avoiding mechanical failures or electrical problems caused by excessively low temperatures.

[0049] Furthermore, to reduce energy consumption, the evaporator 1011 can be equipped with a high-efficiency compressor and expansion valve to ensure minimal energy loss during the refrigerant cycle. In addition, inverter technology and intelligent control systems can adjust the cooling capacity according to actual needs, avoiding unnecessary energy waste. This energy-saving design not only reduces operating costs but also meets the environmental and sustainable development requirements of modern cold storage facilities. Some models also use environmentally friendly refrigerants, reducing ozone layer depletion and greenhouse gas emissions. Despite its complex internal structure and high performance, the evaporator 1011 has a very compact design, suitable for installation in limited spaces. Especially in rooftop units, the evaporator is typically located on the top of the cold storage unit, saving valuable floor space. Simultaneously, the modular design allows for flexible combination of evaporators 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 evaporator assembly 11 also includes an evaporator fan 1012. The primary task of the evaporator fan 1012 is to enhance airflow over the surface of the evaporator 1011 through forced convection, thereby improving heat exchange efficiency. During the refrigeration process, the low-temperature, low-pressure refrigerant absorbs heat from the surrounding air and evaporates into gas within the evaporator. The evaporator fan accelerates the heat transfer process by drawing in warm air from the cold storage and blowing it across the fins of the evaporator. This forced convection significantly increases the contact time and area between the air and the evaporator surface, allowing the refrigerant to absorb heat more quickly and achieving a highly efficient refrigeration effect. To ensure temperature uniformity within the cold storage, the evaporator fan 1012 is also responsible for evenly distributing the cooled air throughout the cold storage space. Through a reasonable duct design and fan placement, the evaporator fan can deliver cold air to every corner, avoiding excessive local temperature differences. This is particularly important for storing temperature-sensitive foods such as fruits, vegetables, and frozen meats. Uniform cold air distribution not only improves the refrigeration effect but also extends the shelf life of food and reduces the risk of food spoilage due to uneven temperature.

[0051] In addition to the evaporator 1011 and evaporator fan 1012, the evaporator assembly 11 may also include multiple auxiliary and control components to ensure its efficient, reliable, and intelligent operation. These additional components work together to optimize the overall performance of the evaporator assembly, improving the refrigeration effect and maintenance convenience of the cold storage. Specifically, these 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 evaporator assembly, improving the refrigeration effect and maintenance convenience of the cold storage. By integrating multiple functions and technologies, the evaporator assembly provides users with a more intelligent and reliable refrigeration solution, meeting the modern cold storage's demands for high efficiency, energy saving, and environmental protection.

[0052] The condenser fan 1021 draws in outside air and blows it across the condenser fins, accelerating heat transfer. This forced convection significantly increases the heat exchange rate between the air and the condenser surface, allowing the high-temperature, high-pressure gaseous refrigerant to release heat and condense into a liquid state more quickly. Through continuous airflow, the condenser fan maintains the temperature difference between the condenser surface and the surrounding air, ensuring the continuity and efficiency of the condensation process. Without the forced convection provided by the fan, relying solely on natural convection would drastically reduce condensation efficiency, leading to a decline in system performance. Condenser fans typically employ variable frequency technology, automatically adjusting their speed based on ambient temperature and system requirements. In high-temperature environments, the fan can increase its speed to enhance heat dissipation; while in low-temperature environments, it can decrease its speed to save energy. This intelligent control not only improves the system's response speed but also optimizes the energy efficiency ratio.

[0053] The condenser 1022 contains a high-temperature, high-pressure gaseous refrigerant, while its exterior exchanges heat with the outside air through fins. The condenser is typically made of copper or aluminum alloy, which have good thermal conductivity, to ensure efficient heat transfer. The finned structure increases the surface area, further improving heat exchange efficiency. When the high-temperature, high-pressure gaseous refrigerant enters the condenser, it transfers heat to the surrounding air through the pipe walls, gradually decreasing its own temperature and condensing into a liquid. During this process, the refrigerant releases a large amount of latent heat, causing its temperature to drop rapidly, ultimately completing the transition from gaseous to liquid. The condenser plays a role in pressure regulation during condensation. As the refrigerant condenses, the pressure within the system gradually balances, preventing damage to the compressor and other components from excessive pressure. Simultaneously, the condenser is connected to the evaporator through a throttling device (such as an expansion valve) to ensure a smooth transition of the refrigerant between different states. Because the external environment of cold storage can be harsh, the condenser typically uses an anti-corrosion coating or stainless steel to prevent corrosion caused by long-term exposure. Furthermore, the condenser's sealing design ensures no refrigerant leakage, guaranteeing the system's safety and reliability.

[0054] The condenser fan 1021 and the condenser 1022 work together during the condensation process to ensure the efficient operation of the refrigeration system. The condenser fan provides the necessary airflow, enhancing the heat dissipation of the condenser; while the condenser, through efficient heat exchange, realizes the transformation of the refrigerant from a gaseous state to a liquid state. Both complement each other and are indispensable, jointly ensuring the stability and energy efficiency ratio of the entire refrigeration system.

[0055] In addition to the condenser fan 1021 and condenser 1022, the condensing assembly 102 may also include temperature and pressure sensors, a cooling water system, anti-corrosion coatings and sealing designs, an intelligent controller, filters and protective covers, and other auxiliary and control components. These components collectively enhance the performance, reliability, and intelligence of the condensing assembly, ensuring efficient operation of the condensing process and optimizing 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 demands 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 heat exchange in the condenser component 102 and, in cleaning mode, clean the evaporator 1011 via the water spray device 1031. The water spray device 1031 is positioned corresponding to the evaporator 1011 to ensure that the water evenly covers the entire evaporator surface. This design not only improves the cleaning effect but also reduces water waste. The water spray device typically consists of multiple nozzles, each with a carefully designed angle and flow rate for optimal spraying. The nozzles are made of corrosion-resistant materials such as stainless steel or engineering plastics to ensure they will not age or break down over long-term use. After the refrigeration equipment 11 activates the cleaning mode, the water in the water storage component 103 is sprayed onto the surface of the evaporator 1011 through the water spray device 1031 to clean it. This cleaning method not only removes dust, dirt, and microorganisms from the evaporator surface but also prevents a decrease in heat exchange efficiency due to long-term accumulation. In particular, regular cleaning can effectively protect the evaporator copper tubes and extend the equipment's lifespan, especially against corrosive substances that may exist in the cold storage environment (such as the acidic components in sauerkraut).

[0057] Due to the special environment of cold storage, the evaporator 1011 may come into contact with corrosive food or harmful substances in the air. The design of the water storage assembly 103 and the water spraying device 1031 fully considers this, employing multiple anti-corrosion measures. For example, the interior of the water storage assembly is coated with an anti-corrosion coating to prevent rust caused by prolonged contact with moisture; the nozzles of the water spraying device are made of corrosion-resistant materials to ensure long-term durability. Furthermore, appropriate anti-corrosion agents can be added to the system to further enhance the anti-corrosion effect. The design of the water storage assembly 103 emphasizes environmental protection, reducing the demand for fresh water resources by recycling condensate. This water-saving design not only reduces operating costs but also aligns with modern environmental protection concepts. Simultaneously, the system is equipped with a water quality monitoring device to ensure that the discharged water meets environmental standards and does not pollute the surrounding environment. Traditional evaporator cleaning usually requires manual intervention, which is time-consuming, labor-intensive, and prone to overlooking details. The automated cleaning function of the water storage assembly 103 greatly simplifies the maintenance process, reducing downtime and labor costs. Especially in top-mounted units, the difficulty of manual cleaning is effectively solved, further improving the reliability and availability of the system. With the rapid development of cold chain logistics and the food processing industry, cold storage is being used in increasingly diverse applications. The innovative design of the water storage component 103 and the water spraying device 1031 provides a more efficient, reliable, and environmentally friendly solution for cold storage refrigeration systems. 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 The diagram shows a partially enlarged structural view of a refrigeration device provided in an embodiment of the present invention.

[0059] In one embodiment, the water storage component 103 further includes: a water storage tank 1032, a water level sensor 1033, and a water pipe 1034; the water storage component 103 is used to transfer water from the water storage tank 1032 to the water spraying device 1031 through the water pipe 1034 to clean the evaporator 1011 when a preset cleaning condition is met; the preset cleaning condition is: the water level sensor 1033 detects that the water level information of the water storage tank 103 has reached a preset water level, and the time since the last cleaning of the evaporator 1011 is greater than a preset cleaning cycle.

[0060] The water storage tank 1032 is the core storage unit of the entire water storage assembly, used to collect and store the water generated by the condenser assembly 102 during heat exchange. The water storage tank 1032 is equipped with an overflow prevention design to prevent leakage accidents caused by excessive water volume. A water level sensor 1033 monitors the water level in the water storage tank 1032 in real time and can feed the data back to the control system. When the water level reaches the preset upper limit, the system automatically starts the drain pump or prompts the user to drain the water, ensuring that the water storage tank does not become overfilled. The water guide pipe 1034 is the transmission channel connecting the water storage tank 1032 and the water spraying device 1031, responsible for guiding the water in the water storage tank to the water spraying device. To achieve precise control, a switch is also equipped in the water guide pipe. When preset cleaning conditions are met, the control system automatically opens this switch, allowing water to flow through the water guide pipe and be transmitted to the water spraying 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 sensor 1033 detects that the water level in the water storage tank 1032 has reached the preset value. This condition ensures that there is sufficient water in the tank for cleaning. If the water level is insufficient, the cleaning effect will be greatly reduced, and the entire cleaning process may not be completed. The time since the last cleaning of the evaporator 1011 is greater than the preset cleaning cycle. This condition prevents cleaning from being too frequent, avoiding unnecessary water waste and equipment wear. Frequent cleaning not only increases energy consumption but may also lead to excessive wetting of the evaporator surface, increasing the risk of frost formation. 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 condenser component 102 has produced enough condensate. This water can be reused for evaporator cleaning, achieving effective water resource recycling. The preset cleaning cycle ensures that the cleaning operation is not too frequent, ensuring the cleanliness of the evaporator while avoiding resource waste.

[0062] When the preset cleaning conditions are met, the control system confirms that there is sufficient water in the water tank 1032 based on data provided by the water level sensor 1033. It then defrosts the evaporator 1011. After defrosting, the evaporator assembly 101 and the condenser assembly 102 are shut off. Subsequently, the control system opens the switch in the water pipe 1034, allowing water to flow through the pipe and be transmitted to the water spraying device 1031. The water spraying device evenly sprays water onto the surface of the evaporator 1011, completing the cleaning process. After cleaning, the system shuts off the switch, stops the water supply, and, if necessary, uses the condenser fan 1022 to help the evaporator surface dry quickly, ensuring it returns to normal operation.

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

[0064] In one embodiment, the system further includes: an air guide assembly 104 connecting the interior and exterior of the cold storage; the interior wall of the cold storage includes a fresh air vent 105; the condenser assembly 102 is used to stop operating after the refrigeration equipment 11 starts cleaning mode until the evaporator 1011 is cleaned; after the evaporator 1011 is cleaned, it starts operating, draws in outdoor air, and transmits the hot air generated by heat exchange with the air to the air guide assembly 104, through which the hot air is transmitted to the interior of the cold storage to dry the moisture after cleaning;

[0065] The air inside the cold storage is transferred to the outside of the cold storage through the air exchange vent.

[0066] When the refrigeration equipment 11 enters the cleaning mode, the condenser assembly 102 and other related components will temporarily stop operating. This is to ensure that no new condensate is generated or the cleaning effect is affected during the cleaning process. During the shutdown period, the evaporator fan 1012 will also stop working to avoid cold air interfering with the cleaning process. This shutdown arrangement ensures that the cleaning operation can be carried out under optimal conditions, preventing incomplete cleaning due to equipment operation. In cleaning mode, the water spraying device 1031 of the water storage assembly 103 sprays water from 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 from the evaporator surface, preventing long-term accumulation from affecting heat exchange efficiency. In particular, for potentially corrosive substances (such as acidic components in sauerkraut), regular cleaning can also effectively protect the evaporator copper tubes and extend the equipment life. After cleaning is completed, the condenser assembly 102 restarts and enters normal operation. At this time, the main task of the condenser assembly is to draw in outdoor air and generate hot air through heat exchange, which is then vented into the cold storage to ensure a dry and safe environment inside the cold storage. Furthermore, the fresh air vents 105 on the inner wall of the cold storage are an important component of the air guiding assembly 104, responsible for introducing fresh air and expelling moisture. This design not only improves cleaning efficiency but also optimizes air quality inside the cold storage, extends equipment lifespan, and ensures the safety and quality of food storage.

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

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

[0069] In refrigeration mode, the primary task of the condenser assembly 102 is to cool and condense the high-temperature, high-pressure gaseous refrigerant into a liquid state. To achieve this, the condenser assembly requires a large amount of outside air to remove heat from the refrigerant. Therefore, the condenser assembly is equipped with a high-efficiency fan system that can quickly draw in outdoor air and guide it to the surface of the condenser 1022 for heat exchange. When outdoor air passes through the condenser 1022, the air inside the condenser is filled with high-temperature, high-pressure gaseous refrigerant. During heat exchange, this refrigerant transfers heat to the drawn-in air, causing the air temperature to rise rapidly, forming hot air. This process not only effectively lowers the temperature of the refrigerant, promoting its condensation into a liquid state, but also ensures the efficient operation of the condenser assembly. If the generated hot air is not discharged in time, it may adversely affect the temperature inside the cold storage. Therefore, the refrigeration equipment 11 is designed with a dedicated path to transport the hot air to the outside of the cold storage through the air guide assembly 104. The air guide assembly typically includes air ducts, pipes, and air outlets to ensure that the hot air can be discharged from the cold storage quickly and smoothly, preventing heat from flowing back into the cold storage.

[0070] The air guide assembly 104 is designed with dedicated air ducts and pipes to ensure that hot air can be quickly and smoothly transferred from the condenser assembly to the outside of the cold storage. These air ducts are typically made of high-temperature resistant materials to withstand the high-temperature environment of the hot air. Through the air outlet located outside the cold storage, the air guide assembly ensures that the hot air is directly exhausted to the outside environment without interfering with the internal temperature of the cold storage. This not only improves the cooling effect but also maintains the temperature stability inside the cold storage.

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

[0072] In cooling mode, the primary task of the evaporator assembly 101 is to absorb warm air from the cold storage and exchange heat through the evaporator 1011, transferring heat from the air to the low-temperature, low-pressure refrigerant, causing it to evaporate into gas. To achieve this, the evaporator assembly is equipped with a high-efficiency evaporator fan 1012, which can quickly draw in air from the cold storage and guide it to the evaporator surface for cooling. When the warm air from the cold storage passes through the evaporator 1011, the refrigerant flowing inside the evaporator is low-temperature, low-pressure. During the heat exchange process, this refrigerant absorbs heat from the air and evaporates, causing the air temperature to drop rapidly, forming cold air. This process not only effectively reduces the air temperature but also ensures the efficient operation of the evaporator assembly, providing a continuous cooling effect. If the generated cold air is not promptly returned to the cold storage, it may lead to uneven local temperatures or a decrease in cooling efficiency. Therefore, the refrigeration equipment 11 is designed with a dedicated path to transport the cold air into the cold storage through the air vents located inside the cold storage via the air guide assembly 104. At this time, the fresh air vent 105 is closed to ensure that the cold air can quickly and smoothly cover all corners of the cold storage.

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

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

[0075] In cleaning mode, the condenser assembly 102 draws in outdoor air and exchanges heat, generating hot air which is then transported to the interior of the cold storage unit via ductwork. The ductwork design ensures that hot air is quickly and smoothly transported from the condenser assembly to the designated location, minimizing heat loss. This efficient transport path allows hot air to be directly directed at the evaporator 1011, helping to quickly dry any residual moisture after cleaning, ensuring the evaporator surface is dry and preventing frost or dampness. The ductwork design not only considers functional requirements but also optimizes space utilization. The ductwork can be flexibly arranged according to the specific layout of the cold storage unit, ensuring it doesn't occupy excessive space while still covering the evaporator 1011. This compact and flexible installation method not only improves space utilization but also simplifies the installation and commissioning process, enhancing construction efficiency.

[0076] In one embodiment, the air 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] By connecting the first pipe 1041, the second pipe 1042, and the third pipe 1043, the hot air generated by the condenser assembly can be transferred to the outside or inside of the cold storage as needed. This not only achieves efficient transmission and precise distribution of hot and cold air but also optimizes space utilization and installation flexibility. The first pipe 1041 ensures that hot air does 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 crucial connecting and transition role. This design not only improves the overall efficiency of the system but also ensures the stability and safety of the cold storage environment, providing users with a more intelligent and reliable refrigeration solution that meets the modern cold storage's demands for high efficiency, energy saving, and environmental protection.

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

[0079] One end of the first pipe 1041 is an air inlet for a duct, and the other end is equipped with a first air leak and a first baffle located at the first air leak. By controlling the closure of the first baffle, the hot air output from the condenser assembly 102 is discharged from the first air leak to the outside of the cold storage. A second air leak is provided on the bottom wall of the second pipe 1042, along with a second baffle. The second air leak has multiple small holes. By providing the second air leak on the bottom wall of the second pipe 1042, the cold air generated by the evaporator assembly 101 can be transmitted to the inside of the cold storage through the multiple small holes of the second air leak. By providing the second baffle located at the second air leak, after the evaporator 1011 has been cleaned, the second baffle can block the second air leak, allowing the hot air generated by the condenser fan 1021 to dry the evaporator 1011 through the air outlet. A third baffle 1044 is installed at the junction of the first pipe 1041 and the third pipe 1043 to control the airflow direction of the hot air generated by the condenser assembly 102. When the first baffle closes the first air leak, the third baffle 1044 opens to allow the air duct to flow smoothly, allowing the hot air generated by the condenser assembly 102 to pass through the third pipe. A fourth baffle 1045 is installed in the third pipe 1043 at a position corresponding to the top wall of the cold storage to separate the inside and outside parts of the cold storage in the pipe. The fourth baffle 1045 opens to allow the air duct to flow smoothly, allowing the hot air generated by the condenser assembly 102 to pass through the third pipe and then through the second pipe to the evaporator 1011.

[0080] The refrigeration device 11 also includes:

[0081] The baffle control module 107 is used to control the first baffle to close the first air leak, control the second baffle to close the second air leak, and control the third baffle 1044 and the fourth baffle 1045 to open the air duct after the evaporator 1011 is cleaned, so that the hot air output by the condenser assembly 102 is transmitted from the air outlet of the air duct to the evaporator 1011.

[0082] After the evaporator 1011 is cleaned, the first control module 1071 controls the first baffle to close the first air leak and controls the third baffle 1044 to open the air duct; 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 open the air duct, so that the hot air output by the condenser assembly 102 is transferred 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 opens the third baffle 1044 to connect the air duct. Simultaneously, 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 open the air duct, ensuring that the hot air output from the condenser assembly 102 can be transferred from the air duct outlet to the evaporator 1011. This design ensures that the cleaned evaporator dries quickly, preventing moisture residue from causing frost or corrosion.

[0084] In one embodiment, the baffle control module 107 is used to control the first baffle to open the first air vent, control the second baffle to open the second air vent, 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 condenser assembly 102 is transmitted from the first air vent to the outside of the cold storage, and the cold air output by the evaporator assembly 101 is transmitted from the second air vent to the inside of the cold storage.

[0085] After the refrigeration equipment 11 starts the refrigeration mode, the first control module 1071 controls the first baffle to open the first air vent, controls the third baffle 1044 to block the air duct, the second control module 1072 controls the second baffle to open the second air vent, and the third control module 1073 controls the fourth baffle 1045 to block the air duct, so that the hot air output by the condensing component 102 is transferred to the outside of the cold storage through the first air vent, and the cold air output by the evaporating component 101 is transferred to the inside of the cold storage through the second air vent.

[0086] After the refrigeration equipment 11 activates its refrigeration mode, the first control module 1071 controls the first baffle to open the first air vent and block the air duct, allowing the hot air output from the condenser assembly 102 to be transferred to the outside of the cold storage through the first air vent. Simultaneously, the second control module 1072 controls the second baffle to open the second air vent, and the third control module 1073 controls the fourth baffle 1045 to block the air duct, allowing the cold air output from the evaporator assembly 101 to be transferred to the inside of the cold storage through the second air vent. This design optimizes heat management and refrigeration effect, ensures the stability and safety of the environment inside the cold storage, and achieves a highly efficient and reliable refrigeration process.

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

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

[0089] The evaporator assembly 101 is located at the top inside the cold storage, while the condenser assembly 102 and water storage assembly 103 are located at the bottom outside the cold storage. This layout design optimizes space utilization, improves system efficiency, and ensures operational safety. 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 the cold storage environment, thus providing a stable and reliable refrigeration solution.

[0090] In one embodiment, the refrigeration device 11 further includes a water receiving tray 106; the water receiving tray 106 is located at the bottom of the evaporator 1011 and corresponds to the water spraying device 1031, and is used to collect the water generated during the cleaning of the evaporator 1011.

[0091] A drip tray 106 is located at the bottom of the evaporator 1011 and corresponds to the water spray device 1031, used to collect water generated during the cleaning process of the evaporator 1011. This design ensures that water generated during cleaning will not overflow or accumulate inside the cold storage, keeping the environment dry and clean. The drip tray not only prevents the floor from becoming slippery, reducing safety hazards, but also prevents water from seeping into the cold storage structure, preventing corrosion and damage. Furthermore, the corresponding position of the drip tray and the water spray device ensures that all sprayed water is effectively collected, improving water resource utilization. By centrally collecting the water after cleaning, the system can further treat or discharge this water, meeting environmental protection requirements, while simplifying maintenance and ensuring the stability and safety of the environment inside the cold storage.

[0092] This invention provides a refrigeration device, comprising: an evaporation assembly deployed inside a cold storage unit, the evaporation assembly including an evaporator; a condensation assembly and a water storage assembly deployed outside the cold storage unit; the water storage assembly including a water spraying device positioned corresponding to the evaporator; the water storage assembly is used to store moisture generated during heat exchange by the condensation assembly, and to clean the evaporator by spraying water onto the evaporator through the water spraying device after the refrigeration device is activated in cleaning mode. This invention, by increasing the water storage assembly to store moisture and cleaning the evaporator through the water spraying device in the water storage assembly during cleaning mode, not only prevents corrosion of the evaporator pipes due to moisture and impurities, but also ensures the high-efficiency heat exchange performance of the evaporator, thereby continuously optimizing the refrigeration effect, extending the equipment's service life, and improving overall operating efficiency and reliability.
