Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration equipment technology, specifically to a refrigerator control method and a refrigerator. Background Technology
[0002] Frost-free refrigerators are generally divided into two types: single-system frost-free refrigerators and dual-system frost-free refrigerators. Single-system frost-free refrigerators have one evaporator located in the freezer compartment. The refrigerant returns to the compressor via the compressor, condenser, capillary tube, and evaporator, forming a complete refrigeration cycle. Its advantages include a relatively small refrigeration duct volume, resulting in more usable space and lower cost. The disadvantage is low humidity in the refrigerator compartment, with a relative humidity of only 15%-40% when the refrigerator is empty, which is detrimental to preservation performance. Dual-system frost-free refrigerators have one evaporator in each compartment, switching between them via a switching valve. Its advantages include a relative humidity of over 75% in the refrigerator compartment, providing excellent preservation of fruits and vegetables. The disadvantages are a larger refrigeration duct component volume, reducing usable space and increasing the cost of the refrigeration duct components. Furthermore, the addition of an electric switching valve to the refrigeration system in dual-system frost-free refrigerators further increases the failure rate of the refrigeration system.
[0003] Therefore, the evaporator can be placed in the central beam between the refrigerator and freezer compartments, with air duct components, partition components, and drainage plates installed to achieve cooling for both the refrigerator and freezer compartments. This reduces the space occupied by the evaporator and also reduces the space occupied by the air duct components within the cabinet, thus increasing the cabinet capacity. However, placing the evaporator in the center changes the position of the evaporator in an existing single-cycle air-cooled refrigerator, making it impossible to achieve the function of independent control of the refrigerator and freezer compartments in a dual-system air-cooled refrigerator. The humidity inside the refrigerator compartment of a single-system air-cooled refrigerator is relatively low. Summary of the Invention

[0022] If the freezing temperature is greater than the freezing shut-off temperature, the refrigeration temperature is less than the refrigeration open temperature, and the evaporation temperature is greater than the first preset temperature, then the refrigeration fan is shut off and the second air inlet damper is closed.

Detailed Implementation
[0049] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.
[0050] Frost-free refrigerators are generally divided into two types: single-system frost-free refrigerators and dual-system frost-free refrigerators. Single-system frost-free refrigerators have one evaporator located in the freezer compartment. The refrigerant returns to the compressor via the compressor, condenser, capillary tube, and evaporator, forming a complete refrigeration cycle. Its advantages include a relatively small refrigeration duct volume, resulting in more usable space and lower cost. The disadvantage is low humidity in the refrigerator compartment, with a relative humidity of only 15%-40% when the refrigerator is empty, which is detrimental to preservation performance. Dual-system frost-free refrigerators have one evaporator in each compartment, switching between them via a switching valve. Its advantages include a relative humidity of over 75% in the refrigerator compartment, providing excellent preservation of fruits and vegetables. The disadvantages are a larger refrigeration duct component volume, reducing usable space and increasing the cost of the refrigeration duct components. Furthermore, the addition of an electric switching valve to the refrigeration system in dual-system frost-free refrigerators further increases the failure rate of the refrigeration system.
[0051] In some embodiments, the evaporator is positioned in the central beam between the refrigerator and freezer compartments, along with an air duct assembly, partition assembly, and drain plate, to achieve cooling for both compartments. In this refrigerator structure, the height space occupied by the evaporator is reduced, as is the space occupied by the air duct assembly within the cabinet, effectively increasing the cabinet capacity. However, this refrigerator's air duct design, which uses the existing single-cycle air-cooled refrigerator's rear evaporator solution and innovatively moves the evaporator to the central beam position to reduce the space occupied by the evaporator and air duct, cannot achieve independent dual-system control of the refrigerator and freezer compartments, and cannot significantly improve the humidity in the single-system refrigerator compartment.
[0052] To address the issue of low humidity in the refrigerator compartment of a single-system air-cooled refrigerator, some embodiments of this application provide a refrigerator control method, see [link to relevant documentation]. Figure 1 , Figure 1 The flowchart of the refrigerator control method provided in this application embodiment specifically includes the following steps:
[0053] S100: Acquire the refrigeration temperature detected by the refrigeration temperature sensor 201, the freezing temperature detected by the freezing temperature sensor 101, and the evaporation temperature detected by the evaporation temperature sensor 301.
[0054] S200: Compare the refrigeration temperature, freezing temperature, and evaporation temperature with preset conditions to generate comparison results.
[0055] The preset conditions include the refrigerator start temperature, freezer start temperature, refrigerator stop temperature, freezer stop temperature, a first preset temperature, and a second preset temperature. By comparing the refrigerator temperature with the refrigerator stop temperature and the refrigerator start temperature, it is determined whether the refrigerator compartment 2 needs cooling. By comparing the freezer temperature with the refrigerator start temperature and the freezer stop temperature, it is determined whether the freezer compartment 1 needs cooling. By comparing the evaporation temperature with the first preset temperature and the second preset temperature, it is determined whether humidification of the refrigerator compartment 2 is needed. In this embodiment, after generating comparison results by comparing the refrigerator temperature, freezer temperature, and evaporation temperature with the preset conditions, the refrigerator is controlled to operate in different modes.
[0056] S300: Based on the comparison results, control the refrigerator to operate in a preset mode.
[0057] In some embodiments, such as Figure 2 As shown, the comparison results are generated by comparing the refrigeration and freezing temperatures with preset conditions, including:
[0058] If the refrigeration temperature is greater than the refrigeration start temperature, the freezing temperature is less than the freezing start temperature, and the evaporation temperature is less than the first preset temperature, then the refrigeration fan 7 is started, the first air supply damper 11 and the first return air damper 9 are closed, and the second air inlet damper 10 is opened.
[0059] If the refrigeration temperature is higher than the refrigeration start temperature, the freezing temperature is lower than the freezing start temperature, and the evaporation temperature is higher than the first preset temperature, then the compressor, the refrigeration fan 7, and the second air inlet damper 10 are controlled to start.
[0060] If the refrigeration temperature is higher than the refrigeration start temperature and the freezing temperature is lower than the freezing start temperature, then the surface refrigeration compartment 2 needs to be refrigerated. At the same time, if the evaporation temperature is lower than the first preset temperature, then the surface refrigeration compartment 2 needs to be humidified. Therefore, the refrigeration fan 7 can be started, the second air inlet damper 10 can be opened, and the first air supply damper 11 and the first return air damper 9 can be closed. After humidifying the refrigeration compartment 2 by opening the second air inlet damper 10, the compressor can be started and the second air inlet damper 10 can be opened to refrigerate the refrigeration compartment 2.
[0061] When the refrigerator compartment 2 needs to be refrigerated, if the evaporation temperature is higher than the first preset temperature, the surface refrigerator compartment 2 does not need to be humidified. Therefore, the compressor can be started and the second air inlet damper 10 can be opened directly to provide cooling for the refrigerator compartment 2.
[0062] It can be understood that the opening and closing of the first air supply damper 11 and the first air return damper 9 controls the cooling of the freezer compartment 1, and the opening and closing of the second air inlet damper 10 controls the cooling of the refrigerator compartment 2. When the second air inlet damper 10 is closed, the low-temperature gas generated by the evaporator 3 cannot enter the refrigerator compartment 2. When the second air inlet damper 10 is open, the refrigeration fan 7 can send the high-humidity gas into the refrigerator compartment 2 through the second air inlet damper 10 to increase the humidity in the refrigerator compartment 2.
[0063] In some embodiments, generating comparison results by comparing refrigeration temperature and freezing temperature with preset conditions further includes:
[0064] If the refrigeration temperature is higher than the refrigeration start temperature and the freezing temperature is higher than the freezing start temperature, then the compressor and refrigeration fan 7 will be started and the second air inlet damper 10 will be opened.
[0065] If the evaporation temperature is lower than the second preset temperature, the first air inlet damper 8 and the first return air damper 9 will be opened.
[0066] If the refrigeration temperature is greater than the refrigeration start temperature and the freezing temperature is greater than the freezing start temperature, it means that both the refrigeration compartment 2 and the freezing compartment 1 need to be refrigerated. Therefore, the refrigeration fan 7 can be started, the second air inlet damper 10 can be opened to refrigerate the refrigeration compartment 2, and the first air inlet damper 8 and the first return air damper 9 can be opened to refrigerate the freezing compartment 1.
[0067] In some embodiments, generating comparison results by comparing refrigeration temperature and freezing temperature with preset conditions further includes:
[0068] If the refrigeration temperature is lower than the refrigeration shut-off temperature, then the second air inlet damper 10 will be closed.
[0069] If the freezing temperature is lower than the freezing shutdown temperature, the compressor will be shut down, and the first supply air damper 11 and the first return air damper 9 will be closed.
[0070] During the cooling process of refrigerator compartment 2 and freezer compartment 1, when the refrigerator temperature is lower than the refrigerator shut-off temperature, the temperature inside refrigerator compartment 2 has already reached its target temperature. Therefore, cooling of refrigerator compartment 2 can be stopped by closing the second air inlet damper 10. When the temperature inside freezer compartment 1 reaches its target temperature, cooling of freezer compartment 1 can be stopped by turning off the compressor, the first air inlet damper 8, and the first return air damper 9. During refrigerator use, the temperature of freezer compartment 1 is lower than that of refrigerator compartment 2. Therefore, it takes longer for freezer compartment 1 to reach its freezing shut-off temperature than for refrigerator compartment 2. Thus, when refrigerator compartment 2 stops cooling, it is not necessary to turn off the compressor; only the second air inlet damper 10 needs to be closed. When freezer compartment 1 stops cooling, the compressor needs to be turned off to reduce energy consumption.
[0071] In some embodiments, generating comparison results by comparing refrigeration temperature and freezing temperature with preset conditions further includes:
[0072] If the refrigeration temperature is greater than the refrigeration shut-off temperature and less than the refrigeration start temperature, and the freezing temperature is greater than the freezing start temperature, then the compressor is started, the first air inlet damper 8 and the first return air damper 9 are opened, and the second air inlet damper 10 and the second return air damper 13 are closed.
[0073] When the refrigeration temperature is higher than the refrigeration closing temperature and lower than the refrigeration opening temperature, the surface refrigeration compartment 2 does not need to be refrigerated. Therefore, it is determined whether the freezing temperature is higher than the freezing opening temperature. When the freezing temperature is higher than the freezing opening temperature, the surface freezer compartment 1 needs to be refrigerated separately. Therefore, the compressor can be started, and the first air inlet damper 8 and the first air return damper 9 are opened to provide cooling for the freezer compartment 1. At the same time, the refrigeration compartment 2 does not need to be refrigerated. Therefore, the second air inlet damper 10 can be closed to prevent cold air from entering the refrigeration compartment 2, thereby improving the cooling efficiency of the freezer compartment 1.
[0074] In some embodiments, generating comparison results by comparing refrigeration temperature and freezing temperature with preset conditions further includes:
[0075] If the freezing temperature is lower than the freezing shut-off temperature, the refrigeration temperature is lower than the refrigeration start-up temperature, and the evaporation temperature is lower than the first preset temperature, then the refrigeration fan 7 is started, the second air inlet damper 10 is opened, and the first air supply damper 11 and the first return air damper 9 are closed.
[0076] If the freezing temperature is lower than the freezing shut-off temperature, the refrigeration temperature is lower than the refrigeration start-up temperature, and the evaporation temperature is higher than the first preset temperature, then the refrigeration fan 7 will be shut off and the second air inlet damper 10 will be shut off.
[0077] If the freezing temperature is lower than the freezing shut-off temperature, the surface freezer compartment 1 does not require refrigeration. Therefore, the first air supply damper 11 and the first return air damper 9 can be closed to reduce heat exchange between the freezer compartment 1 and the outside air. If the refrigeration temperature is lower than the refrigeration start temperature and the evaporation temperature is lower than the first preset temperature, humidification is required in the surface refrigeration compartment 2. The second air inlet damper 10 can be opened, and the refrigeration fan 7 can be used to deliver high-humidity outside air into the refrigeration compartment 2 to increase the humidity inside the refrigeration compartment 2. When the evaporator 3 temperature is higher than or lower than the preset temperature, humidification of the surface refrigeration compartment 2 is complete. At this point, the refrigeration fan 7 and the second air inlet damper 10 can be closed to shut off the airflow between the refrigeration compartment 2 and the outside air.
[0078] In some embodiments, the refrigerator start temperature, refrigerator stop temperature, freezer start temperature, and freezer stop temperature are all associated with the refrigerator's cooling setting. For example, the refrigerator start temperature is 2–10°C, the refrigerator stop temperature is 0–8°C, the freezer start temperature is -12°C to -22°C, and the freezer stop temperature is -16°C to -26°C. The refrigerator start temperature, freezer stop temperature, freezer start temperature, and freezer stop temperature all change with the refrigerator's cooling setting.
[0079] In addition, the first preset temperature is -5℃ to -1℃, and the second preset temperature is -15℃ to -25℃.

When the first air inlet damper 8 is opened, the cold air generated by the evaporator 3 can enter the air duct through the first air inlet damper 8, and then enter the freezer compartment 1 through the first air supply damper 11. The gas in the freezer compartment 1 can enter the partition assembly 4 through the first return air damper 9 to exchange heat with the evaporator 3 again.
