Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigerator and a refrigerator defrosting control method. Background Technology

[0002] In the field of food preservation and processing, the thawing process, as a crucial link between frozen storage and subsequent cooking, directly impacts the final quality of food. With consumers increasingly prioritizing food safety and nutrient retention, effectively maintaining the original flavor of food and minimizing nutrient loss during thawing has become a focus of industry attention. Particularly in home and commercial kitchen environments, there is an urgent need for efficient, safe, and convenient thawing solutions to meet the demand for quickly processing frozen ingredients.

[0003] To address the aforementioned needs, existing technologies primarily employ two defrosting solutions. The first utilizes a low-temperature, high-humidity defrosting chamber or equipment. This solution employs the coordinated operation of a fan, a misting humidifier, and a refrigeration system to generate a low-temperature, high-humidity air environment for food defrosting. The second solution utilizes the high-temperature, high-humidity air generated during the defrosting process in a refrigerator's freezer compartment for defrosting, aiming to reduce energy consumption and simplify operation through a natural process.

[0004] However, for low-temperature, high-humidity thawing storage facilities or thawing equipment, the introduction of atomizing humidifiers not only increases operational complexity, requiring regular water replenishment and cleaning to prevent water contamination, but may also adversely affect the internal environment of the refrigerator's cold storage compartment, causing problems such as evaporator frosting, abnormal cooling, and condensation on structural surfaces, thereby affecting thawing efficiency and food quality. While utilizing the high-temperature, high-humidity air during the defrosting process in the cold storage compartment simplifies operations, the temperature in the cold storage compartment may soar to 9-12 degrees Celsius during defrosting. Excessive thawing time can lead to over-thawing of the meat surface, severe loss of blood and moisture, and significant nutrient loss. Summary of the Invention

Detailed Implementation

[0044] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0045] Because some technologies require additional defrosting equipment to defrost food, and the defrosting process can cause the surface of meat to thaw, resulting in significant loss of blood and moisture, this application provides a refrigerator and a refrigerator defrosting control method to solve this technical problem. The refrigerator and refrigerator defrosting control method are described below:

[0046] like Figure 2 The diagram shown is a schematic representation of the internal structure of the refrigerator in this application.

[0047] The first aspect of this application provides a refrigerator, comprising:

[0048] Refrigeration compartment 1, wherein a refrigeration fan 11 is installed in the refrigeration compartment 1, such as Figure 1 As shown; the refrigeration fan 11 is used to accelerate the dissipation speed of cold air in the refrigeration chamber 1, thereby accelerating the refrigeration speed of the refrigeration chamber 1.

[0049] The thawing chamber 2 is located inside the refrigerator compartment 1; the thawing chamber 2 is used to thaw food placed inside the thawing chamber 2.

[0050] Evaporator chamber 3 contains an evaporator 31, which is one of the core components of the refrigeration cycle. When low-temperature, low-pressure liquid refrigerant flows into the evaporator, it absorbs heat from the surrounding environment (such as air, water, or other media) and evaporates into a gaseous state. This process lowers the temperature of the medium surrounding the evaporator, thereby achieving a cooling effect on the refrigerator compartment 1 and the thawing compartment 2. For example, the evaporator 3 absorbs heat from the refrigerator compartment 1 and the thawing compartment 2, causing the temperature inside the refrigerator compartment 1 and the thawing compartment 2 to drop, achieving the purpose of cooling; it can also remove moisture from the air through condensation (dehumidification). At the same time, the low surface temperature of the evaporator can cause water vapor in the refrigerator compartment 1 and the thawing compartment 2 to condense into liquid water, further regulating the humidity inside the refrigerator compartment 1 and the thawing compartment 2.

[0051] The refrigerator compartment 1 is connected to the evaporator compartment 3 via a first air duct 12; the defrost compartment 2 is connected to the evaporator compartment 3 via a second air duct 21; the first air duct 12 is provided with a first damper 121, and the second air duct 21 is provided with a second damper 211; opening the first damper 121 enables cooling of the refrigerator compartment 1, and opening the second damper 211 enables cooling of the defrost compartment 2. That is, by providing the first damper 121 and the second damper 211, independent cooling of the refrigerator compartment 1 or the defrost compartment 2, as well as simultaneous cooling, can be achieved.

[0052] Controller 4 is connected to the first damper 121, the second damper 211, the evaporator 31, and the refrigeration fan 11 respectively; controller 4 is configured to:

[0053] In response to a defrost command, the refrigerator compartment temperature and the defrost compartment temperature are obtained. The defrost command can be triggered by the user to activate the refrigerator's defrost function, or by clicking the refrigerator's display panel to activate the defrost function of defrost compartment 2. It is worth noting that the triggering of the defrost command is not limited in this embodiment.

[0054] The refrigerator compartment 1 is equipped with a first temperature sensor 13, which is connected to the controller 4. The first temperature sensor 13 is configured as follows:

[0055] Obtain the temperature of the refrigerator compartment 1.

[0056] A second temperature sensor 23 is installed inside the defrosting chamber 2. The second temperature sensor 23 is connected to the controller 4. The second temperature sensor 23 is configured as follows:

[0057] Obtain the temperature of the thawing chamber 2.

[0058] The defrosting chamber 2 is equipped with a defrosting fan 22; the defrosting fan 22 is connected to the controller 4; the controller 4 is further configured to:

[0059] In response to the defrosting command, the defrosting fan 22 is turned on.

[0060] This application utilizes the defrosting fan 22 to accelerate air circulation and promote heat transfer. The defrosting fan 22 forces airflow, breaking up any temperature stratification or stagnant zones that may exist within the defrosting chamber 2, ensuring that hot air (or air at a specific temperature) is evenly distributed across the surface of the items being defrosted. Compared to natural convection, forced air circulation via the defrosting fan 22 significantly improves heat transfer efficiency and shortens defrosting time. For example, in defrosting frozen food, the fan can quickly bring surrounding hot air to the food surface, accelerating the melting of ice crystals. It also improves defrosting uniformity; if the air in the defrosting chamber 2 is stagnant, different parts of the item (such as the center and surface) may defrost unevenly due to temperature differences, or even result in localized overheating or thawing. The defrosting fan 22 continuously circulates air, ensuring that the air temperature and flow rate are consistent across all surfaces of the defrosted item, avoiding localized temperature differences. For example, in defrosting meat, the fan ensures that the meat is heated evenly throughout, reducing juice loss. It also prevents condensation buildup and reduces microbial growth. During the thawing process, condensation may form on the surface of the item. The thawing fan 22 accelerates airflow to promote moisture evaporation and prevent excessive local humidity.

[0061] The temperature of the refrigerator compartment is compared with a first preset temperature value. If the temperature of the refrigerator compartment is greater than the first preset temperature, a first comparison result is generated. The first preset temperature is any value between 5.1°C and 8°C.

[0062] Specifically, if the temperature of the refrigerator compartment is higher than the first preset temperature, the evaporator 31 and the refrigerator cooling fan 11 are turned on until the temperature inside the refrigerator compartment 1 reaches the refrigerator compartment shutdown temperature. Since the defrosting chamber 2 is located inside the refrigerator compartment, to prevent the temperature of the refrigerator compartment 1 from becoming too high during the defrosting process and to ensure food safety, the defrosting process usually requires temperature control within a specific range (e.g., 2℃-5℃) to prevent items (e.g., meat, seafood) from rapidly multiplying bacteria or deteriorating due to excessively high temperatures. If the temperature of the refrigerator compartment exceeds the first preset temperature, it indicates that the ambient temperature has approached or exceeded the safe defrosting range. At this time, turning on the evaporator 31 and the refrigerator cooling fan 11 can quickly bring the temperature back to a safe range (e.g., drop it to the refrigerator compartment shutdown temperature), preventing the food in the refrigerator compartment 1 from spoiling.

[0063] If the temperature of the refrigerator compartment is less than or equal to the first preset temperature, the temperature of the thawing compartment is compared with the second preset temperature value. If the temperature of the thawing compartment is less than or equal to the second preset temperature value, a second comparison result is generated. The second preset temperature is any value between 2°C and 5°C.

[0064] Specifically, if the temperature of the refrigerator compartment is less than or equal to the first preset temperature and the temperature of the defrosting compartment is less than or equal to the second preset temperature, then the refrigerator cooling fan 11 and the first damper 121 are turned on, and the evaporator 31 is turned off. The low-temperature environment of the refrigerator compartment 1 is used to assist defrosting, improving energy efficiency. The defrosting process requires temperature control within a safe range to prevent spoilage. When the temperature of the refrigerator compartment is less than or equal to the first preset temperature and the temperature of the defrosting compartment is less than or equal to the second preset temperature, it indicates that the refrigerator compartment 1 itself is already in a relatively low-temperature environment. By turning off the evaporator 31, active cooling through the evaporator 31 is unnecessary, reducing compressor running time and energy consumption. By turning on the refrigerator cooling fan 11, the cold air in the refrigerator compartment 1 is circulated and introduced into the defrosting compartment 2, utilizing the existing low-temperature environment to assist defrosting. Furthermore, by using the defrosting fan 22 to mix the high-temperature and humid air in the refrigerator compartment with the relatively low-temperature air in the defrosting compartment 2, the humidity in the defrosting compartment can be effectively increased during defrosting, thus avoiding the drawback of uncontrolled defrosting temperature during defrosting in existing technologies.

[0065] It is worth noting that the first air damper 121 is the airflow channel switch between the refrigerator compartment 1 and the thawing compartment 2. After the refrigerator cooling fan 11 is turned on, the cold air in the refrigerator compartment 1 can flow into the thawing compartment 2 in a directional manner, forming a controllable airflow path, which can evenly reduce the temperature of the thawing compartment 2 and reduce the temperature difference.

[0066] If the thawing chamber temperature remains below the second preset temperature, the surface of the thawed items may refreeze, damaging cell structure and affecting taste and nutrition. Therefore, this application avoids excessively low thawing chamber temperatures due to active cooling by shutting off the evaporator 31. By introducing slightly warmer air from the refrigerator compartment 1, the thawing chamber temperature slowly rises to a safe range, preventing the food from refreezing.

[0067] If the temperature of the defrosting chamber is greater than the second preset temperature value, a third comparison result is generated.

[0068] Specifically, if the temperature of the defrosting chamber is higher than the second preset temperature value, the evaporator 31, the second damper 211, and the refrigeration fan 11 are activated until the temperature inside the defrosting chamber 2 reaches the defrosting chamber shutdown temperature. During the defrosting process, if the temperature of the defrosting chamber remains higher than the second preset temperature value, it may lead to rapid bacterial growth on the surface of the item or uneven defrosting inside. This application addresses this by activating the evaporator 31: the evaporator is the core component of the refrigeration system, absorbing heat through refrigerant circulation to directly lower the temperature of the defrosting chamber. It also optimizes temperature uniformity by precisely controlling the airflow through the second damper 211; the second damper 211 is the air duct connecting the defrosting chamber 2 and the evaporator 31, controlling the direction and flow rate of cold air. After activation, the cold air generated by the evaporator 31 can flow directionally into the defrosting chamber 2, avoiding waste of cooling capacity. Through the second damper 211, cold air can preferentially flow to the high-temperature area, quickly balancing the temperature.

[0069] Based on the first comparison result, the second comparison result, and the third comparison result, the refrigeration fan 11, the first damper 121, and the second damper 211 are controlled to open or close.

[0070] This application provides a refrigerator that utilizes a method to maintain a constant temperature difference between the refrigerator compartment 1 and the defrosting compartment 2, ensuring that both compartments are consistently maintained at a constant temperature. The refrigerator compartment operates within a temperature range of 5.1–8°C, and the defrosting compartment operates within a temperature range of 5°C. During non-cooling periods, the refrigerator cooling fan 11 returns moisture to the refrigerator compartment 1, maintaining high humidity. During defrosting, the defrosting fan 22 mixes the hot, humid air from the refrigerator compartment 1 with the relatively cool air from the defrosting compartment 2, effectively increasing the humidity in the defrosting compartment 2 and avoiding the drawback of uncontrolled defrosting temperature during defrosting in existing technologies. Furthermore, by consistently maintaining the temperature of the defrosting compartment 2 within the optimal range of 2–5°C, the food surface is prevented from experiencing severe defrosting due to high temperatures.

[0071] This application provides a refrigerator that does not require additional humidification devices. It utilizes the mixing of relatively high-temperature, high-humidity air in the refrigerator compartment 1 with low-temperature air in the defrost compartment 2 to form low-temperature, high-humidity air. During defrosting, the defrost compartment 2 maintains a constant temperature within the range of 2-5°C. The temperature difference between the surface and center of the meat is small, and the temperature gradient is uniform as the temperature transfer occurs from the center of the meat outwards. The surface ice crystals continuously absorb internal cold energy, extending the latent heat exchange time. Therefore, even if the defrosting time is long, severe thawing will not occur on the surface, and the food contains very little blood under constant temperature conditions, preserving nutrients to the maximum extent.

[0072] A second aspect of this application provides a refrigerator defrosting control method, applied to a refrigerator as described in any of the above embodiments, comprising:

[0073] In response to a defrost command, obtain the refrigerator compartment temperature and the defrost compartment temperature;

[0074] The temperature of the refrigerator compartment is compared with a first preset temperature value. If the temperature of the refrigerator compartment is greater than the first preset temperature, a first comparison result is generated.

[0075] If the temperature of the refrigerator compartment is less than or equal to the first preset temperature, the temperature of the thawing compartment is compared with the second preset temperature value. If the temperature of the thawing compartment is less than or equal to the second preset temperature value, a second comparison result is generated.

[0076] If the temperature of the defrosting chamber is greater than the second preset temperature value, a third comparison result is generated;

[0077] Based on the first comparison result, the second comparison result, and the third comparison result, the refrigeration fan, the first damper, and the second damper are controlled to open or close.

[0078] It is worth noting that the effects of the above method embodiments can be found in the effects of the above system embodiments, and will not be repeated here.
