Detailed Implementation

[0030] To better understand the above-mentioned objects, features, and advantages of the embodiments according to this application, the embodiments according to this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features of the embodiments according to this application can be combined with each other.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the embodiments according to this application. However, the embodiments according to this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection provided by the embodiments according to this application is not limited to the specific embodiments disclosed below.

[0032] The following reference Figures 1 to 12 Some embodiments according to this application are described.

[0033] Example 1

[0034] like Figure 1 As shown, a refrigeration system 100 is provided according to an embodiment of the first aspect of this application. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, and a gas storage chamber 104.

[0035] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 is equipped with an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0036] The evaporator 108 is used for heat exchange and cooling with the gas in the cooling chamber 106, and the fan 112 drives the cold air to flow through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to achieve the purpose of food preservation. Of course, the cold air may also flow to the gas storage chamber 104 at the same time to exchange heat with the hot air in the gas storage chamber 104 and lower its temperature.

[0037] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is designed to defrost evaporator 108. By heating evaporator 108 with the defrosting device 110, the frost layer melts. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108. The air storage chamber 104 stores at least some of the hot air, preventing it from directly heating storage chamber 101. During defrosting, this helps slow down the temperature rise of storage chamber 101, reducing the possibility of overheating and ensuring a suitable environment and effective preservation of food. It is understandable that some of the hot air may be driven by the fan 112 to the air duct 102 and then enter the storage chamber 101 through the air duct 102. However, due to the setting of the air storage chamber 104, the amount of hot air entering the storage chamber 101 is greatly reduced, so the impact of hot air on the temperature of the storage chamber 101 is greatly reduced.

[0038] It should be noted that the gas storage chamber 104 is a semi-enclosed structure, connected only to the refrigeration chamber 106. Therefore, the entire refrigeration system 100 remains a closed structure, not connected to the external environment. In some related technologies, the hot air generated during defrosting is directly discharged to the outside of the refrigeration equipment 10, which makes it difficult to seal the refrigeration equipment 10 and is not conducive to maintaining a low-temperature environment inside the refrigeration equipment 10. However, the technical solution of this application sets up a gas storage chamber 104 to isolate the hot air, and it is not connected to the external environment, which helps to ensure the heat preservation effect inside the refrigeration equipment 10, and facilitates maintaining a low-temperature environment inside the refrigeration equipment 10, especially the storage chamber 101.

[0039] Example 2

[0040] According to another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, and a gas storage chamber 104.

[0041] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 is equipped with an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0042] The refrigeration chamber 106 has both a refrigeration state and a defrosting state. The evaporator 108 is used for heat exchange and cooling with the gas inside the refrigeration chamber 106. When the evaporator 108 is cooling, the refrigeration chamber 106 is in a refrigeration state. The cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment inside the storage chamber 101 to achieve the purpose of food preservation. Of course, the cooled air may also partially flow into the gas storage chamber 104 at the same time to exchange heat with the hot air inside the gas storage chamber 104 and lower its temperature. In the refrigeration state, the first damper 120 is open to ensure that the cooled air can enter the air duct 102 and flow to the storage chamber 101.

[0043] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0044] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 is closed, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Driven by the fan 112, the hot air can only flow to the air storage chamber 104. At this time, the air storage chamber 104 can store all the hot air. Through the cooperation of the first damper 120 and the air storage chamber 104, the hot air no longer flows to the air duct 102 and enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by the hot air, further reducing the impact of the hot air on the temperature of the storage chamber 101, thereby helping to further ensure the freshness of the food.

[0045] It should be noted that the gas storage chamber 104 is a semi-enclosed structure, connected only to the refrigeration chamber 106. Therefore, the entire refrigeration system 100 remains a closed structure, not connected to the external environment. In some related technologies, the hot air generated during defrosting is directly discharged to the outside of the refrigeration equipment 10, which makes it difficult to seal the refrigeration equipment 10 and is not conducive to maintaining a low-temperature environment inside the refrigeration equipment 10. However, the technical solution of this application sets up a gas storage chamber 104 to isolate the hot air, and it is not connected to the external environment, which helps to ensure the heat preservation effect inside the refrigeration equipment 10, and facilitates maintaining a low-temperature environment inside the refrigeration equipment 10, especially the storage chamber 101.

[0046] Example 3

[0047] According to another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a first damper 120, and a second damper 122.

[0048] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0049] The refrigeration chamber 106 has both a refrigeration state and a defrosting state. The evaporator 108 is used for heat exchange and cooling with the gas inside the refrigeration chamber 106. When the evaporator 108 is cooling, the refrigeration chamber 106 is in a refrigeration state. The cooled air after heat exchange and cooling is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment inside the storage chamber 101 to achieve the purpose of food preservation. Of course, the cooled air may also flow to the gas storage chamber 104 at the same time to exchange heat with the hot air inside the gas storage chamber 104 and lower its temperature. In the refrigeration state, the first damper 120 is open to ensure that the cooled air can enter the air duct 102 and flow to the storage chamber 101. At the same time, the second damper 122 is closed, so that the cooled air, driven by the fan 112, flows entirely into the air duct 102, thereby preventing some of the cooled air from flowing into the gas storage chamber 104 and causing a loss of cooling capacity.

[0050] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0051] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there. Through the coordination of the first damper 120, the second damper 122, and the air storage chamber 104, hot air no longer flows to the air duct 102 but instead enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by hot air. This further reduces the impact of hot air on the temperature of the storage chamber 101, thus further ensuring the freshness of the food.

[0052] In addition, when in cooling mode, the second door is closed, preventing hot air from interfering with the cooling process within the air storage chamber 104, thereby reducing the impact of hot air on the cooling of the evaporator 108. This helps improve the cooling efficiency of the storage chamber 101.

[0053] It should be noted that the gas storage chamber 104 is a semi-enclosed structure, connected only to the refrigeration chamber 106. Therefore, the entire refrigeration system 100 remains a closed structure, not connected to the external environment. In some related technologies, the hot air generated during defrosting is directly discharged to the outside of the refrigeration equipment 10, which makes it difficult to seal the refrigeration equipment 10 and is not conducive to maintaining a low-temperature environment inside the refrigeration equipment 10. However, the technical solution of this application sets up a gas storage chamber 104 to isolate the hot air, and it is not connected to the external environment, which helps to ensure the heat preservation effect inside the refrigeration equipment 10, and facilitates maintaining a low-temperature environment inside the refrigeration equipment 10, especially the storage chamber 101.

[0054] like Figure 3 As shown, a thermal insulation layer 114 is further provided between the refrigeration chamber 106 and the gas storage chamber 104. A second damper 122 is disposed within the thermal insulation layer 114. By using the thermal insulation layer 114, after hot air enters the gas storage chamber 104, closing the second damper 122 helps to better block the exchange of heat between the gas storage chamber 104 and the refrigeration chamber 106, thereby reducing the rate of temperature change within the gas storage chamber 104. This further reduces the impact of hot air on the storage chamber 101 and the cold air in the refrigeration chamber 106. It can be understood that the thermal insulation performance of the thermal insulation layer 114 makes it difficult for hot air and cold air inside and outside the second damper 122 to exchange heat, which helps to maintain the gas in the storage chamber 101 and the refrigeration chamber 106 within a lower temperature range.

[0055] Example 4

[0056] According to yet another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a first damper 120, a second damper 122, and a controller.

[0057] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0058] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas in the refrigeration chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108 to defrost the evaporator 108 and generates hot gas.

[0059] When the evaporator 108 is cooling, the cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to preserve the food. Of course, some of the cooled air may also flow into the air storage chamber 104 to exchange heat with the hot air inside, lowering its temperature. In cooling mode, the first damper 120 is open to ensure that cooled air can enter the air duct 102 and flow into the storage chamber 101. Simultaneously, the second damper 122 is closed, causing all the cooled air, driven by the fan 112, to flow into the air duct 102, thus preventing some cooled air from flowing into the air storage chamber 104 and causing a loss of cooling capacity.

[0060] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0061] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there. Through the coordination of the first damper 120, the second damper 122, and the air storage chamber 104, hot air no longer flows to the air duct 102 but instead enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by hot air. This further reduces the impact of hot air on the temperature of the storage chamber 101, thus further ensuring the freshness of the food.

[0062] In addition, when in cooling mode, the second door is closed, preventing hot air from interfering with the cooling process within the air storage chamber 104, thereby reducing the impact of hot air on the cooling of the evaporator 108. This helps improve the cooling efficiency of the storage chamber 101.

[0063] Furthermore, in this embodiment, the controller is electrically connected to the defrosting device 110. Simultaneously, the controller is also electrically connected to the first damper 120 and the second damper 122. Through this electrical connection, the controller can obtain the operating status of the defrosting device 110. By obtaining the operating status of the defrosting device 110, it can be determined whether hot air is generated in the refrigeration chamber 106. When the defrosting device 110 is operating and defrosting the evaporator 108, hot air is generated. At this time, the controller controls the first damper 120 to close, preventing hot air from flowing through the air duct 102 to the storage chamber 101 and affecting the preservation of food. Simultaneously, the controller also controls the second damper 122 to open, opening the gas storage chamber 104, allowing hot air to flow into the gas storage chamber 104 for storage under the drive of the fan 112. After the defrosting device 110 stops operating, no more hot air is generated. The controller, after determining that no more hot air is being generated by acquiring the operating status of the defrosting device 110, controls the second damper 122 to close, so that all the hot air is sealed in the storage chamber 104. Under the influence of the internal ambient temperature of the refrigeration system 100, the air is slowly cooled down, reducing and essentially avoiding the impact on the temperature of the storage chamber 101. At the same time, the first damper 120 is opened so that the cold air from the evaporator 108 can flow to the storage chamber 101 through the air duct 102.

[0064] The controller allows for intelligent control of the opening and closing of the first damper 120 and the second damper 122, eliminating the need for manual operation and making the refrigeration system 100 and refrigeration equipment 10 more convenient to use. Furthermore, the controller's control of the two dampers based on the operating status of the defrosting device 110 helps ensure the timely opening and closing of the two dampers, further reducing the possibility of hot air entering the storage chamber 101 via the air duct 102.

[0065] Example 5

[0066] like Figure 4 As shown, a refrigeration system 100 is provided according to another embodiment of the first aspect of this application. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

[0067] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0068] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas in the refrigeration chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108 to defrost the evaporator 108 and generates hot gas.

[0069] When the evaporator 108 is cooling, the cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to preserve the food. Of course, some of the cooled air may also flow into the air storage chamber 104 to exchange heat with the hot air inside, lowering its temperature. In cooling mode, the first damper 120 is open to ensure that cooled air can enter the air duct 102 and flow into the storage chamber 101. Simultaneously, the second damper 122 is closed, causing all the cooled air, driven by the fan 112, to flow into the air duct 102, thus preventing some cooled air from flowing into the air storage chamber 104 and causing a loss of cooling capacity.

[0070] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0071] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there. Through the coordination of the first damper 120, the second damper 122, and the air storage chamber 104, hot air no longer flows to the air duct 102 but instead enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by hot air. This further reduces the impact of hot air on the temperature of the storage chamber 101, thus further ensuring the freshness of the food.

[0072] In addition, when in cooling mode, the second door is closed, preventing hot air from interfering with the cooling process within the air storage chamber 104, thereby reducing the impact of hot air on the cooling of the evaporator 108. This helps improve the cooling efficiency of the storage chamber 101.

[0073] Furthermore, in this embodiment, a temperature sensor 116 is provided inside the refrigeration chamber 106. The temperature sensor 116 is connected to the controller. The temperature sensor 116 is located inside the refrigeration chamber 106 to detect the temperature of the refrigeration chamber 106 and determine its state. Specifically, a preset value can be set. When the detected temperature is lower than the preset value, the refrigeration chamber 106 is determined to be in a refrigeration state; when the detected temperature is greater than or equal to the preset value, the refrigeration chamber 106 is determined to be in a defrosting state. The controller is electrically connected to the temperature sensor 116. Simultaneously, the controller is also electrically connected to the first damper 120 and the second damper 122, respectively. Through the electrical connection with the temperature sensor 116, the controller can determine the state of the refrigeration chamber 106 by its temperature, thereby determining whether hot air is generated inside the refrigeration chamber 106. When the detected temperature is greater than or equal to the preset value, the refrigeration chamber 106 is in a defrosting state, and the controller controls the first damper 120 to close, preventing hot air from flowing through the air duct 102 into the storage chamber 101 and affecting the preservation of food. Simultaneously, the controller also controls the second damper 122 to open, opening the air storage chamber 104, allowing hot air to flow into the air storage chamber 104 for storage under the drive of the fan 112. When the detected temperature is lower than the preset value, the cooling chamber 106 is in cooling mode, and the controller controls the second damper 122 to close, so that all the hot air is sealed inside the air storage chamber 104. Under the influence of the internal ambient temperature of the cooling system 100, the air is slowly cooled down, reducing and basically avoiding the impact on the temperature of the storage chamber 101. At the same time, the first damper 120 is opened so that the cold air from the evaporator 108 heat exchange and cooling can flow to the storage chamber 101 through the air duct 102.

[0074] The controller allows for intelligent control of the opening and closing of the first damper 120 and the second damper 122, eliminating the need for manual operation and making the refrigeration system 100 and refrigeration equipment 10 more convenient to use. Furthermore, the controller's control of the two dampers based on the temperature of the refrigeration chamber 106 ensures timely opening and closing of the dampers, further reducing the possibility of hot air entering the storage chamber 101 via the air duct 102. Even if the refrigeration chamber 106 heats up due to reasons other than defrosting, the hot air can be promptly driven into the air storage chamber 104, preventing any impact on the food preservation effect and environment of the storage chamber 101.

[0075] Furthermore, the temperature sensor 116 is located at the air inlet ring 126 of the rear cover of the air duct 102. At this location, adjacent to the fan 112, the temperature near the air duct 102 and the air storage chamber 104 can be obtained more accurately, which helps to improve the accuracy of control.

[0076] Example 6

[0077] According to yet another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

[0078] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0079] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas in the refrigeration chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108 to defrost the evaporator 108 and generates hot gas.

[0080] When the evaporator 108 is cooling, the cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to preserve the food. Of course, some of the cooled air may also flow into the air storage chamber 104 to exchange heat with the hot air inside, lowering its temperature. In cooling mode, the first damper 120 is open to ensure that cooled air can enter the air duct 102 and flow into the storage chamber 101. Simultaneously, the second damper 122 is closed, causing all the cooled air, driven by the fan 112, to flow into the air duct 102, thus preventing some cooled air from flowing into the air storage chamber 104 and causing a loss of cooling capacity.

[0081] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0082] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there. Through the coordination of the first damper 120, the second damper 122, and the air storage chamber 104, hot air no longer flows to the air duct 102 but instead enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by hot air. This further reduces the impact of hot air on the temperature of the storage chamber 101, thus further ensuring the freshness of the food.

[0083] In addition, when in cooling mode, the second door is closed, preventing hot air from interfering with the cooling process within the air storage chamber 104, thereby reducing the impact of hot air on the cooling of the evaporator 108. This helps improve the cooling efficiency of the storage chamber 101.

[0084] In this embodiment, a temperature sensor 116 is installed inside the cooling chamber 106. The temperature sensor 116 is electrically connected to the controller. Simultaneously, the controller is also electrically connected to the defrosting device 110. The temperature sensor 116 is installed inside the cooling chamber 106 to detect the temperature of the cooling chamber 106 and provide feedback to the controller. Simultaneously, the controller also acquires the operating status of the defrosting device 110. More specifically, the controller determines the operating status of the defrosting device 110 based on its power. The controller simultaneously acquires the operating status of the defrosting device 110 and the temperature of the cooling chamber 106 to determine the state of the cooling chamber 106. Specifically, when the power of the defrosting device 110 is greater than zero and the temperature of the cooling chamber 106 is greater than or equal to a preset value, the cooling chamber 106 is determined to be in a defrosting state. At this time, the second damper 122 is opened, and the first damper 120 is closed. Alternatively, when the power of the defrosting device 110 is equal to zero, the cooling chamber 106 is determined to be in a cooling state. At this time, the second damper 122 can be closed, and the first damper 120 can be opened. Alternatively, when the temperature of the cooling chamber 106 is lower than the preset value, it can also be determined that the cooling chamber 106 is in a cooling state.

[0085] Example 7

[0086] According to yet another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

[0087] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0088] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas in the refrigeration chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108 to defrost the evaporator 108 and generates hot gas.

[0089] When the evaporator 108 is cooling, the cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to preserve the food.

Simultaneously, the second damper 122 is closed, causing all the cooled air, driven by the fan 112, to flow into the air duct 102, thus preventing some cooled air from flowing into the air storage chamber 104 and causing a loss of cooling capacity.

[0090] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0091] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there. Through the coordination of the first damper 120, the second damper 122, and the air storage chamber 104, hot air no longer flows to the air duct 102 but instead enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by hot air. This further reduces the impact of hot air on the temperature of the storage chamber 101, thus further ensuring the freshness of the food.

[0092] In addition, when in cooling mode, the second door is closed, preventing hot air from interfering with the cooling process within the air storage chamber 104, thereby reducing the impact of hot air on the cooling of the evaporator 108. This helps improve the cooling efficiency of the storage chamber 101.

[0093] Furthermore, the air storage chamber 104 is spaced apart from the storage chamber 101. The air storage chamber 104 is mainly used to store hot air. Its separation from the storage chamber 101 increases the distance between them. It is understood that both the air storage chamber 104 and the storage chamber 101 are part of the refrigeration system 100, and direct or indirect heat exchange is inevitable. By separating them and increasing the distance between them, the heat exchange between them is further reduced, thereby better reducing the heating of the storage chamber 101 by the hot air. Similarly, the air storage chamber 104 is also spaced apart from the air duct 102, thereby reducing the heating of the air duct 102, and correspondingly reducing the temperature impact on the storage chamber 101.

[0094] A temperature sensor 116 is installed inside the refrigeration chamber 106. The temperature sensor 116 is electrically connected to the controller. The controller is also electrically connected to the defrosting device 110. The temperature sensor 116 is located inside the refrigeration chamber 106 to detect the temperature of the refrigeration chamber 106 and provide feedback to the controller. Simultaneously, the controller also acquires the operating status of the defrosting device 110. More specifically, the controller determines the operating status of the defrosting device 110 based on its power. The controller simultaneously acquires the operating status of the defrosting device 110 and the temperature of the refrigeration chamber 106 to determine the state of the refrigeration chamber 106. Specifically, when the power of the defrosting device 110 is greater than zero and the temperature of the refrigeration chamber 106 is greater than or equal to a preset value, the refrigeration chamber 106 is determined to be in defrosting mode. At this time, the second damper 122 is opened, and the first damper 120 is closed. Alternatively, when the power of the defrosting device 110 is equal to zero, the refrigeration chamber 106 is determined to be in cooling mode. At this time, the second damper 122 can be closed, and the first damper 120 can be opened. Alternatively, when the temperature of the cooling chamber 106 is lower than the preset value, it can also be determined that the cooling chamber 106 is in a cooling state.

[0095] Example 8

[0096] According to yet another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

[0097] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0098] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas in the refrigeration chamber 106.

This helps improve the cooling efficiency of the storage chamber 101.

[0103] Furthermore, the air storage chamber 104 is spaced apart from the storage chamber 101. The air storage chamber 104 is mainly used to store hot air. Its spaced-apart arrangement with the storage chamber 101 helps to increase the distance between them. It is understood that both the air storage chamber 104 and the storage chamber 101 are part of the refrigeration system 100, and direct or indirect heat exchange is inevitable. By spaced-apart them, the distance between them is increased, which helps to further reduce heat exchange between them, thereby better reducing the heating of the storage chamber 101 by the hot air. Similarly, the air storage chamber 104 is arranged along the length of the air duct 102 and spaced apart from it. Figure 2 As shown, the air storage chamber 104 is arranged along the length of the air duct 102, making it approximately a long and narrow structure. This design helps to reduce the thickness of the air storage chamber 104, increasing the contact area between the hot air and the wall of the air storage chamber 104, thereby accelerating the cooling of the hot air and reducing its impact on the storage chamber 101. Furthermore, the long and narrow shape of the air storage chamber 104 facilitates the use of the available space inside the refrigeration system 100, improving space utilization. The spaced arrangement of the air storage chamber 104 and the air duct 102 helps to reduce heating of the air duct 102, which in turn reduces the temperature impact on the storage chamber 101.

[0104] A temperature sensor 116 is installed inside the refrigeration chamber 106. The temperature sensor 116 is electrically connected to the controller.

[0105] Example 9

[0106] According to yet another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

[0107] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104. Both the gas storage chamber 104 and the duct 102 are located on the same side of the fan 112. This same-side arrangement allows the fan 112 to drive the gas to either the duct 102 or the gas storage chamber 104 without needing to change direction, simplifying the structure.

[0108] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas in the refrigeration chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108 to defrost the evaporator 108 and generates hot gas.

[0109] When the evaporator 108 is cooling, the cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to preserve the food. Of course, some of the cooled air may also flow into the air storage chamber 104 to exchange heat with the hot air inside, lowering its temperature. In cooling mode, the first damper 120 is open to ensure that cooled air can enter the air duct 102 and flow into the storage chamber 101. Simultaneously, the second damper 122 is closed, causing all the cooled air, driven by the fan 112, to flow into the air duct 102, thus preventing some cooled air from flowing into the air storage chamber 104 and causing a loss of cooling capacity.

The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0111] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there.

The air storage chamber 104's arrangement along the length of the air duct 102 makes it approximately a long and narrow structure. This helps to reduce the thickness of the air storage chamber 104, increasing the contact area between the hot air and the side walls of the air storage chamber 104, thereby accelerating the cooling of the hot air and reducing its impact on the storage chamber 101. Furthermore, the elongated shape of the air storage chamber 104 facilitates the use of the spare space inside the refrigeration system 100, thereby improving space utilization. The air storage chamber 104 and the air duct 102 are spaced apart, which helps to reduce the heating of the air duct 102, and consequently reduces the impact on the temperature of the storage chamber 101.

Alternatively, when the temperature of the cooling chamber 106 is lower than the preset value, it can also be determined that the cooling chamber 106 is in a cooling state.

[0115] Example 10

[0116] According to yet another embodiment of the first aspect of this application, a refrigeration system 100 is provided. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

[0117] Specifically, both the storage chamber 101 and the gas storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration chamber 106 contains an evaporator 108, a defrosting device 110, and a fan 112. A duct 102 connects the refrigeration chamber 106 and the storage chamber 101, and they are connected through the duct 102. A first damper 120 is provided on the duct 102. A second damper 122 is provided between the gas storage chamber 104 and the refrigeration chamber 106. The fan 112 drives the gas in the refrigeration chamber 106, causing the gas to flow through the duct 102 to the storage chamber 101, or directly to the gas storage chamber 104. Both the gas storage chamber 104 and the duct 102 are located on the same side of the fan 112. This same-side arrangement allows the fan 112 to drive the gas to either the duct 102 or the gas storage chamber 104 without needing to change direction, simplifying the structure.

[0118] The refrigeration chamber 106 has a refrigeration state and a defrosting state. In the refrigeration state, the evaporator 108 is used for heat exchange and refrigeration with the gas inside the refrigeration chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108 to defrost it and generate hot gas. The evaporator 108 is located between the fan 112 and the defrosting device 110. Further, the evaporator 108 is located at the bottom of the gas storage chamber 104. The defrosting device 110 is located at the bottom of the evaporator 108. Alternatively, the top of the evaporator 108 has the gas storage chamber 104 and the air duct 102, and the bottom of the evaporator 108 has the defrosting device 110. That is, the defrosting device 110 is on the side of the evaporator 108 away from the gas storage chamber 104. The defrosting device 110 is located at the bottom of the evaporator 108. After the evaporator 108 is heated, the hot air rises naturally and further rises naturally into the air storage chamber 104, thereby reducing the workload and power consumption of the fan 112. The evaporator 108 is located between the fan 112 and the defrosting device 110, that is, the fan 112 is at the top of the evaporator 108. This structure facilitates the acceleration of the hot air rise by the fan 112, thereby quickly extracting the hot air into the air storage chamber 104.

[0119] When the evaporator 108 is cooling, the cooled air after heat exchange is driven by the fan 112 and flows through the air duct 102 to the storage chamber 101, thereby ensuring a low-temperature environment in the storage chamber 101 to preserve the food. Of course, some of the cooled air may also flow into the air storage chamber 104 to exchange heat with the hot air inside, lowering its temperature. In cooling mode, the first damper 120 is open to ensure that cooled air can enter the air duct 102 and flow into the storage chamber 101. Simultaneously, the second damper 122 is closed, causing all the cooled air, driven by the fan 112, to flow into the air duct 102, thus preventing some cooled air from flowing into the air storage chamber 104 and causing a loss of cooling capacity.

[0120] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is provided to defrost evaporator 108. When defrosting evaporator 108, cooling chamber 106 is in a defrosting state. The frost layer melts by heating evaporator 108 through defrosting device 110. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108.

[0121] When the refrigeration chamber 106 is in defrosting mode, the first damper 120 closes, sealing the air duct 102 and blocking the flow of hot air to the storage chamber 101. Simultaneously, the second damper 122 opens, and driven by the fan 112, all the hot air flows to the air storage chamber 104 and is stored there. Through the coordination of the first damper 120, the second damper 122, and the air storage chamber 104, hot air no longer flows to the air duct 102 but instead enters the storage chamber 101, completely avoiding direct heating of the storage chamber 101 by hot air. This further reduces the impact of hot air on the temperature of the storage chamber 101, thus further ensuring the freshness of the food.

[0122] In addition, when in cooling mode, the second door is closed, preventing hot air from interfering with the cooling process within the air storage chamber 104, thereby reducing the impact of hot air on the cooling of the evaporator 108. This helps improve the cooling efficiency of the storage chamber 101.

[0123] Furthermore, the air storage chamber 104 is spaced apart from the storage chamber 101. The air storage chamber 104 is mainly used to store hot air. Its spaced-apart arrangement with the storage chamber 101 increases the distance between them. It is understood that both the air storage chamber 104 and the storage chamber 101 are part of the refrigeration system 100, and direct or indirect heat exchange is inevitable. By spaced-apart them, the distance between them is increased, which helps to further reduce heat exchange and thus better reduce the heating of the storage chamber 101 by the hot air. Similarly, the air storage chamber 104 is arranged along the length of the air duct 102 and spaced apart from it. The arrangement of the air storage chamber 104 along the length of the air duct 102 makes it approximately a long and narrow structure. This helps to reduce the thickness of the air storage chamber 104, increasing the contact area between the hot air and the walls of the air storage chamber 104, thereby accelerating the cooling of the hot air and reducing its impact on the storage chamber 101. Furthermore, the elongated shape of the air storage chamber 104 facilitates the use of the spare space inside the refrigeration system 100, thereby improving space utilization. The air storage chamber 104 and the air duct 102 are spaced apart, which helps to reduce the heating of the air duct 102, and consequently reduces the impact on the temperature of the storage chamber 101.

[0124] A temperature sensor 116 is installed inside the refrigeration chamber 106. The temperature sensor 116 is electrically connected to the controller. The controller is also electrically connected to the defrosting device 110. The temperature sensor 116 is located inside the refrigeration chamber 106 to detect the temperature of the refrigeration chamber 106 and provide feedback to the controller. Simultaneously, the controller also acquires the operating status of the defrosting device 110. More specifically, the controller determines the operating status of the defrosting device 110 based on its power. The controller simultaneously acquires the operating status of the defrosting device 110 and the temperature of the refrigeration chamber 106 to determine the state of the refrigeration chamber 106. Specifically, when the power of the defrosting device 110 is greater than zero and the temperature of the refrigeration chamber 106 is greater than or equal to a preset value, the refrigeration chamber 106 is determined to be in defrosting mode. At this time, the second damper 122 is opened, and the first damper 120 is closed. Alternatively, when the power of the defrosting device 110 is equal to zero, the refrigeration chamber 106 is determined to be in cooling mode. At this time, the second damper 122 can be closed, and the first damper 120 can be opened. Alternatively, when the temperature of the cooling chamber 106 is lower than the preset value, it can also be determined that the cooling chamber 106 is in a cooling state.

[0125] Example 11

[0126] A refrigeration system 100 is provided according to an embodiment of the first aspect of this application. The refrigeration system 100 includes a storage chamber 101, a refrigeration chamber 106, a gas storage chamber 104, and a three-way valve.

[0127] Specifically, both the storage chamber 101 and the air storage chamber 104 are connected to the refrigeration chamber 106. The refrigeration system 100 also includes an air duct 102. The three-way valve has a first port, a second port, and a third port. The first port connects to the refrigeration chamber 106. The second port connects to one end of the air duct 102, and the other end of the air duct 102 connects to the storage chamber 101. The third port connects to the air storage chamber 104. When the defrosting device 110 stops operating and the evaporator 108 is cooling, the first and second ports are connected, allowing the refrigeration chamber 106 to connect to the storage chamber 101 via the three-way valve and the air duct 102, and cold air enters the storage chamber 101. When the defrosting device 110 is operating and the evaporator 108 stops working, the first and third ports are connected. At this time, the refrigeration chamber 106 connects to the air storage chamber 104 via the three-way valve, and hot air enters the air storage chamber 104.

[0128] The fan 112 is used to drive the gas in the refrigeration chamber 106, so that the gas flows through the air duct 102 to the storage chamber 101, or directly to the gas storage chamber 104.

[0129] Evaporator 108 absorbs heat and cools for extended periods, and its surface may frost over. This frost layer can affect airflow near evaporator 108, reducing its cooling efficiency. The defrosting device 110 is used to defrost evaporator 108. By heating evaporator 108 with the defrosting device 110, the frost layer melts. The hot air generated by the frost layer, driven by fan 112, can enter and be stored in air storage chamber 104, where it slowly cools under ambient temperature and the cooling effect of evaporator 108. The air storage chamber 104 and the three-way valve guide the hot air to the air storage chamber 104 during defrosting, preventing it from directly heating storage chamber 101. This slows down the temperature rise of storage chamber 101 during defrosting, reducing the possibility of overheating and ensuring a suitable environment and effective preservation of food.

[0130] It should be noted that the gas storage chamber 104 is a semi-enclosed structure, connected only to the refrigeration chamber 106. Therefore, the entire refrigeration system 100 remains a closed structure, not connected to the external environment. In some related technologies, the hot air generated during defrosting is directly discharged to the outside of the refrigeration equipment 10, which makes it difficult to seal the refrigeration equipment 10 and is not conducive to maintaining a low-temperature environment inside the refrigeration equipment 10. However, the technical solution of this application sets up a gas storage chamber 104 to isolate the hot air, and it is not connected to the external environment, which helps to ensure the heat preservation effect inside the refrigeration equipment 10, and facilitates maintaining a low-temperature environment inside the refrigeration equipment 10, especially the storage chamber 101.

[0131] Example 12

[0132] like Figure 5 As shown, a refrigeration device 10 is provided according to an embodiment of the second aspect of this application, including a housing 124 and a refrigeration system 100 as described in any of the embodiments of the first aspect above. The refrigeration system 100 is disposed within the housing 124.

[0133] The refrigeration device 10 provided according to the embodiments of the second aspect of this application, by employing the refrigeration system 100 of any of the embodiments of the first aspect, possesses all the beneficial technical effects of the above embodiments, which will not be repeated here. The enclosure 124 facilitates the provision of protection and insulation for the refrigeration system 100.

[0134] The refrigeration equipment 10 includes any one of a refrigerator, freezer, or freezer. The refrigeration compartment 106 can be the freezer compartment or refrigerator compartment of a refrigerator, or other compartments. The storage compartment can be the freezer compartment or refrigerator compartment of a refrigerator.

[0135] Example 13

[0136] like Figure 8As shown, an embodiment of the third aspect of this application provides a control method for a refrigeration system. The refrigeration system includes a refrigeration chamber, a storage chamber, a gas storage chamber, a first damper, a second damper, and a defrosting device. The first damper is provided between the refrigeration chamber and the storage chamber, and the second damper is provided between the refrigeration chamber and the gas storage chamber. The defrosting device is disposed in the refrigeration chamber. The control method includes:

[0137] Step S100: Obtain the status of the cooling chamber;

[0138] Step S102: Based on the state of the refrigeration chamber, control the opening and closing of the first and second air dampers to connect the refrigeration chamber and the storage chamber, or connect the refrigeration chamber and the gas storage chamber.

[0139] According to the control method provided in the third aspect of this application, by controlling the opening and closing of the first and second dampers, the refrigeration chamber can be connected to either the storage chamber or the gas storage chamber. Thus, the gas flow differs depending on the operating state of the refrigeration chamber. Specifically, in the refrigeration state, the refrigeration chamber and the storage chamber can be connected, allowing cold air to flow into the storage chamber for cooling, ensuring a low-temperature environment for food preservation. In the defrosting state, the refrigeration chamber and the gas storage chamber can be connected, allowing the hot air generated during defrosting to flow into the gas storage chamber for storage, thereby reducing or avoiding heating of the storage chamber by hot air and helping to maintain a low-temperature environment for food preservation.

[0140] Example 14

[0141] like Figure 9 As shown, according to an embodiment of the third aspect of this application, another control method is provided for a refrigeration system. The refrigeration system includes a refrigeration chamber, a storage chamber, a gas storage chamber, a first damper, a second damper, and a defrosting device. A first damper is provided between the refrigeration chamber and the storage chamber, and a second damper is provided between the refrigeration chamber and the gas storage chamber. The defrosting device is disposed within the refrigeration chamber. The control method includes:

[0142] Step S200: Obtain the operating power of the defrosting device;

[0143] Step S202: Determine whether the operating power of the defrosting device is greater than zero;

[0144] Step S204: If not, open the first damper, close the second damper, and connect the refrigeration chamber and the storage chamber;

[0145] Step S206: If yes, close the first damper and open the second damper to connect the refrigeration chamber and the gas storage chamber.

[0146] In this embodiment, the operating power of the defrosting device can be used to determine whether the defrosting device is working. That is, the operating power of the defrosting device determines the state of the refrigeration chamber. When the operating power is greater than zero, it indicates that the defrosting device is operating and defrosting the evaporator, generating hot air. Therefore, the first damper is closed to prevent hot air from flowing through the air duct into the storage chamber and affecting the food's preservation. Simultaneously, the second damper is opened, opening the storage chamber and allowing hot air to flow into it for storage under the drive of the fan. After the defrosting device stops operating, its operating power is no longer greater than zero, and no more hot air is generated. At this time, the second damper is closed, so that all the hot air is sealed in the storage chamber, slowly cooling down under the influence of the internal ambient temperature of the refrigeration system, reducing and essentially eliminating its impact on the storage chamber's temperature. Simultaneously, the first damper is opened to allow the cold air from the evaporator's heat exchange to flow through the air duct into the storage chamber, lowering the storage chamber temperature and ensuring the food's preservation environment and preservation effect.

[0147] Example 15

[0148] like Figure 10 As shown, according to an embodiment of the third aspect of this application, another control method is provided for a refrigeration system. The refrigeration system includes a refrigeration chamber, a storage chamber, a gas storage chamber, a first damper, a second damper, and a defrosting device. The first damper is provided between the refrigeration chamber and the storage chamber, and the second damper is provided between the refrigeration chamber and the gas storage chamber. The defrosting device is disposed within the refrigeration chamber. The control method includes:

[0149] Step S300: Obtain the temperature of the cooling chamber;

[0150] Step S302: Determine whether the temperature of the cooling chamber is greater than or equal to the preset temperature;

[0151] Step S304: If not, open the first damper, close the second damper, and connect the refrigeration chamber and the storage chamber;

[0152] Step S306: If so, close the first damper and open the second damper to connect the refrigeration chamber and the gas storage chamber.

[0153] In this embodiment, by acquiring the temperature of the refrigeration chamber, it can be determined whether there is hot air inside and whether it will affect the temperature of the storage chamber. That is, when the temperature is greater than or equal to a preset value, it indicates that the temperature of the refrigeration chamber is high and hot air is generated. Therefore, the first damper is closed to prevent hot air from flowing into the storage chamber through the air duct and affecting the preservation effect of the food. At the same time, the second damper is opened, opening the storage chamber, allowing hot air to flow into the storage chamber for storage under the drive of the fan. When the temperature of the refrigeration chamber is lower than the preset value, it indicates that there is no longer hot air. At this time, the second damper is closed, so that all the hot air is sealed in the storage chamber, and under the influence of the internal ambient temperature of the refrigeration system, it is slowly cooled down, reducing and basically avoiding the impact on the temperature of the storage chamber. At the same time, the first damper is opened so that the cold air from the evaporator heat exchange and cooling can flow into the storage chamber through the air duct, lowering the temperature of the storage chamber and ensuring the preservation environment and preservation effect of the food.

[0154] Example 16

[0155] like Figure 11 As shown, according to an embodiment of the third aspect of this application, another control method is provided for a refrigeration system. The refrigeration system includes a refrigeration chamber, a storage chamber, a gas storage chamber, a first damper, a second damper, and a defrosting device. The first damper is provided between the refrigeration chamber and the storage chamber, and the second damper is provided between the refrigeration chamber and the gas storage chamber. The defrosting device is disposed within the refrigeration chamber. The control method includes:

[0156] Step S400: Obtain the operating power of the defrosting device and the temperature of the refrigeration chamber;

[0157] Step S402: Determine whether the operating power of the defrosting device is greater than zero and the temperature of the refrigeration chamber is greater than or equal to the preset temperature. If not, proceed to step S410.

[0158] Step S404: If yes, close the first damper and open the second damper to connect the refrigeration chamber and the gas storage chamber;

[0159] Step S406: Obtain the operating power of the defrosting device and the temperature of the refrigeration chamber;

[0160] Step S408: Determine if any of the following conditions exist: the operating power of the defrosting device is zero, or the temperature of the refrigeration chamber is lower than the preset temperature. If not, proceed to step S402; if yes, proceed to step S410.

[0161] Step S410: Open the first air damper, close the second air damper, and connect the refrigeration chamber and the storage chamber.

[0162] In this embodiment, when the defrosting device's operating power is greater than zero and the temperature of the refrigeration chamber is greater than a preset value, it indicates that the defrosting device has started defrosting and has reached a certain level, causing the temperature of the refrigeration chamber to rise to a value greater than or equal to the preset value. At this time, the first air damper is closed, and the second air damper is opened. The first air damper is closed to prevent hot air from flowing into the storage chamber through the air duct and affecting the preservation effect of the food. At the same time, the second air damper is opened, opening the air storage chamber, allowing hot air to flow into the air storage chamber for storage under the drive of the fan.

[0163] When the defrosting device's power is zero, or the temperature of the refrigeration chamber is lower than the preset value, it indicates that the refrigeration chamber temperature has begun to drop. Therefore, the second damper can be closed, allowing all the hot air to be trapped in the storage chamber. Under the influence of the internal ambient temperature of the refrigeration system, the air cools down slowly, reducing and essentially eliminating the impact on the storage chamber temperature. Simultaneously, the first damper opens, allowing the cold air from the evaporator's heat exchange to flow through the air duct to the storage chamber, lowering the storage chamber temperature and ensuring a suitable environment and effective preservation of the food.

[0164] In this embodiment, the operating power of the defrosting device and the temperature of the refrigeration chamber are used simultaneously to detect the status of the refrigeration chamber. This helps to more accurately determine the situation inside the refrigeration chamber and ensure that the first and second air dampers open and close at appropriate times, thereby better reducing the impact of hot air on the storage chamber.

[0165] Example 17

[0166] like Figure 6 As shown, another embodiment of this application provides a refrigeration device 10, which includes a refrigeration chamber 106, a storage chamber 101, a gas storage chamber 104, a first damper 120, and a second damper 122. The refrigeration device 10 further includes: an acquisition device 134 for acquiring the state of the refrigeration chamber 106; and a control device 136 for controlling the opening and closing of the first damper 120 and the second damper 122 according to the state of the refrigeration chamber 106, so that the refrigeration chamber 106 and the storage chamber 101 are connected, or the refrigeration chamber 106 and the gas storage chamber 104 are connected.

[0167] The refrigeration equipment provided in this application embodiment, by setting up an acquisition device 134 and a control device 136, can control the opening and closing of the first damper 120 and the second damper 122, so that the refrigeration chamber 106 is connected to either the storage chamber 101 or the gas storage chamber 104. Thus, the gas flow direction differs depending on the operating state of the refrigeration chamber 106. Specifically, in the refrigeration state, the refrigeration chamber 106 and the storage chamber 101 can be connected, allowing cold air to flow into the storage chamber 101 for refrigeration, ensuring a low-temperature environment for food preservation. In the defrosting state, the refrigeration chamber 106 and the gas storage chamber 104 can be connected, allowing the hot air generated during defrosting to flow into the gas storage chamber 104 for storage, thereby reducing or avoiding heating of the storage chamber 101 by hot air, which helps maintain a low-temperature environment for food preservation.

[0168] Example 18

[0169] like Figure 7 As shown, another embodiment of this application provides a refrigeration device 10, including: a memory 130 and a processor 132, wherein the memory 130 stores a computer program or instructions that can be run on the processor 132, and the processor 132 executes the computer program or instructions to implement the steps of the control method of any of the above embodiments, and thus has the technical effects of any of the above embodiments, which will not be repeated here.

[0170] Example 19

[0171] Another embodiment of this application provides a readable storage medium in which a computer program or instruction, when executed by a processor 132, implements the steps of the control method of any of the above embodiments, and thus has the technical effects of any of the above embodiments, which will not be repeated here.

[0172] Example 20

[0173] A refrigeration system 100 according to a specific embodiment of this application includes an air duct 102 and an air storage chamber 104. The air duct 102 is provided with a first air damper 120, and the air storage chamber 104 is provided with a second air damper 122.

[0174] Specifically, such as Figure 1 As shown, the refrigeration system 100 includes: a fan 112, a first damper 120, a second damper 122, an air duct 102, and a gas storage chamber 104. The gas storage chamber 104 is used to store hot gas.

[0175] like Figure 2 and Figure 3 As shown, the second air damper 122 is placed between the refrigerator compartment and the freezer compartment of the refrigeration equipment, that is, within the insulation layer 114 between the refrigeration compartment 106 and the storage compartment 101. The insulation layer 114 can be a foam layer or a sponge layer. The second air damper 122 is wrapped and fixed by embedded parts.

[0176] like Figure 3 As shown, a temperature sensor 116 is used to sense the temperature, thereby controlling the opening and closing of the second damper 122. The temperature sensor 116 is installed on the air inlet ring of the rear cover of the air duct 102, vertically above the air inlet ring.

[0177] like Figure 12 As shown, the control method of the second damper is simple, and it can be controlled only by defrosting power and temperature sensor temperature, which is safe and reliable.

[0178] The specific control steps are as follows:

[0179] Step S500: Obtain the defrosting power P and the temperature sensor temperature T;

[0180] Step S502: Determine whether P > 0 and T ≥ -6℃. If yes, proceed to step S504; otherwise, proceed to step S508.

[0181] Step S504: The second air damper is opened;

[0182] Step S506: Determine whether T < -6℃ or P = 0. If yes, proceed to step S508; otherwise, proceed to step S502.

[0183] Step S508: The second air damper is closed.

[0184] This specific embodiment utilizes a hot gas bypass method, taking advantage of the principle of rising hot gas, to collect hot gas into a closed space, namely a gas storage chamber. After separate storage, the temperature of the hot gas is not significantly different from the ambient temperature, and the impact of temperature fluctuations is minimal.

[0185] This specific embodiment has the following beneficial effects:

[0186] 1) Hot air can be stored and used inside the refrigeration system 100.

[0187] 2) By using hot air bypass, the hot air is collected into the gas storage chamber 104 using the principle of hot air rising. Considering that the temperature of the hot air is not much different from the ambient temperature, the temperature fluctuation has little impact.
