Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigerator with a pretreatment compartment. Background Technology

[0002] With the continuous improvement of people's living standards and the acceleration of the pace of life, refrigerators, as a common household appliance, have expanded their function beyond simply storing food. In daily life, users often use refrigerators to perform pre-processing of food, such as thawing frozen food or using the low-temperature environment for marinating. These pre-processing techniques are becoming increasingly important in modern cooking preparation, affecting the efficiency of subsequent cooking and the quality of food processing.

[0003] Currently, in refrigerator design and application, most refrigerator manufacturers focus more on optimizing storage functions, such as improving refrigeration and freezing capabilities, increasing storage space, and improving the rationality of compartment layout. However, the development of food pre-processing compartments is relatively limited. In actual use, when users need to use the refrigerator to thaw or otherwise pre-process food, they often have to rely on the low-temperature air inside the refrigerator to act on the food through natural convection to achieve the purpose of pre-processing.

[0004] The existing technology that relies on natural convection of low-temperature air for pretreatment has significant shortcomings. Due to the low efficiency of natural convection, the time required for thawing food or completing other pretreatment processes is relatively long. This extended pretreatment time undoubtedly impacts the efficiency of the entire cooking preparation process for users, resulting in a poor user experience when using the refrigerator for pretreatment and failing to adequately meet users' needs for efficient and convenient food pretreatment.

[0024] 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.

[0025] With the continuous improvement of people's living standards and the acceleration of the pace of life, refrigerators, as a common household appliance, have expanded their function beyond simply storing food. In daily life, users often use refrigerators to perform pre-processing of food, such as thawing frozen food or using the low-temperature environment for marinating. These pre-processing techniques are becoming increasingly important in modern cooking preparation, affecting the efficiency of subsequent cooking and the quality of food processing.

[0026] Currently, in refrigerator design and application, most refrigerator manufacturers focus more on optimizing storage functions, such as improving refrigeration and freezing capabilities, increasing storage space, and improving the rationality of compartment layout. However, the development of food pre-processing compartments is relatively limited. In actual use, when users need to use the refrigerator to thaw or otherwise pre-process food, they often have to rely on the low-temperature air inside the refrigerator to act on the food through natural convection to achieve the purpose of pre-processing.

[0027] The existing technology that relies on natural convection of low-temperature air for pretreatment has significant shortcomings. Due to the low efficiency of natural convection, the time required for thawing food or completing other pretreatment processes is relatively long. This extended pretreatment time undoubtedly impacts the efficiency of the entire cooking preparation process for users, resulting in a poor user experience when using the refrigerator for pretreatment and failing to adequately meet users' needs for efficient and convenient food pretreatment.

[0028] Therefore, to address the issue of poor user experience when using refrigerators for pre-processing operations, and the inability to adequately meet users' needs for efficient and convenient food pre-processing, this application provides a refrigerator with a pre-processing compartment that integrates ripening and defrosting functions into the same compartment, meeting the needs of users in different scenarios. The fan is located outside the drawer for easy wiring and convenient access for users. The drawer bottom is designed with a wave-like shape to facilitate airflow under food and does not occupy storage space compared to traditional support shelves. The refrigerator with a pre-processing compartment provided by this application can quickly defrost and also perform drying and ripening, meeting the needs of users in different scenarios.

[0029] In some embodiments, such as Figures 1 to 3 This application provides a refrigerator with a pre-processing compartment. The refrigerator 1 includes a pre-processing compartment 10. The pre-processing compartment 10 is disposed in the refrigerator compartment of the refrigerator 1. The pre-processing compartment 10 includes a drawer 110 and a fan assembly 111. The fan assembly 111 is disposed outside the drawer 110. Air outlets 112 are provided on both sides of the drawer 110. A top cover 120 is provided on the top of the drawer 110.

[0030] Based on the low-temperature environment of a refrigerator, this application integrates the defrosting and ripening functions into a single space, namely the pre-treatment compartment 10, by constructing a pre-treatment chamber. The pre-treatment compartment 10 is located in the refrigerator compartment of the refrigerator 1, and the cavity is sealed for moisture retention. The pre-treatment compartment includes a drawer 110 and an external fan assembly 111.

[0031] This application integrates the curing and defrosting functions into the same compartment to meet the needs of users in different scenarios; the fan assembly 111 is set outside the drawer 110 to facilitate fan wiring and make it convenient for users to pull out items.

[0032] In some embodiments, a ventilation grille 113 is provided at the center of the rear end of the drawer 110 to allow cooling air to enter.

[0033] In some embodiments, the ventilation grille 113 is connected to the fan assembly 111, and the fan assembly 111 is an axial flow fan.

[0034] In this application, air outlets 112 are provided above the front ends on both sides of the drawer 110, and a ventilation grille 113 for cooling air to enter is provided at the center of the rear end of the drawer 110. An axial fan is located outside the ventilation grille 113, near the air duct 20 on the rear wall of the refrigerator 1. The air intake volume is controlled by adjusting the speed of the axial fan. The airflow path inside the drawer 110 is bottom in and top out. After the fan assembly 111 draws in the cold air near the air duct 20, it is blown from the ventilation grille 113 at the rear end of the drawer 110 to the bottom of the drawer 110 and then blown out from the top.

[0035] In some embodiments, the bottom of the drawer 110 is provided with a wavy protrusion 114.

[0036] In this application, the bottom of the drawer 110 is designed as a wave-shaped protrusion 114, which facilitates the flow of food at the bottom and does not take up storage space compared to traditional support racks.

[0037] This application features a three-dimensional air duct 20 and air outlet 112, enabling cold or hot air to circulate in all directions and at multiple angles within the pretreatment chamber 10. This ensures that all parts of the food are heated or cooled evenly, improving the uniformity and efficiency of pretreatment. For example, for larger pieces of meat, the three-dimensional airflow circulation can remove heat more quickly, achieving rapid defrosting.

[0038] In some embodiments, the refrigerator 1 is provided with an air duct 20, and a sterilization device 210 is provided in the air duct 20 near the pretreatment chamber 10.

[0039] In some embodiments, the sterilization device 210 is one of an ion generator, an ultraviolet lamp, or a plasma generator.

[0040] A plasma sterilization system is introduced into the pre-processing room 10. By generating plasma, it kills bacteria, viruses, mold and other microorganisms on the surface of food and in the air, providing a clean and hygienic environment for food pre-processing, reducing the risk of food contamination and extending the shelf life of food.

[0041] In the structural design of the pre-processing room 10, partitioning and independent air ducts are adopted to prevent cross-contamination of odors and juices between different ingredients, ensuring that the pre-processed ingredients retain their original flavor and improving food safety performance.

[0042] In this application, a duct 20 for supplying cold air is located near the pretreatment room 10. A sterilization device 210 is installed in the duct 20. When the duct 20 supplies cold air, the sterilization device 210 operates to sterilize the air inside the duct 20, ensuring that the cold air supplied to the pretreatment room 10 is clean. The sterilization device 210 can be an ion generator, or it can be an ultraviolet lamp or a plasma generator.

[0043] In some embodiments, the pretreatment chamber 10 further includes a magnetic field device for generating a magnetic field covering the pretreatment chamber.

[0044] In some embodiments, a pressure sensor is provided at the bottom of the inner wall of the pretreatment chamber 10.

[0045] In some embodiments, the inner wall of the pretreatment chamber 10 is equipped with a temperature and humidity sensor.

[0046] In some embodiments, the pretreatment chamber 10 is equipped with a controller, which is electrically connected to the pressure sensor and the temperature and humidity sensor.

[0047] In some embodiments, the controller in this application uses technologies such as image recognition and sensors to automatically identify the ingredients placed in the pretreatment chamber 10, determine the type, weight, initial state and other information of the ingredients, and then automatically match the best pretreatment mode according to the characteristics of the ingredients, such as the temperature, humidity, airflow speed and time required for thawing, marinating and preservation, so as to achieve precise control.

[0048] By installing multiple high-precision temperature and humidity sensors in the pretreatment chamber 10, the temperature and humidity changes within the chamber are monitored in real time, and the data is fed back to the control system. The control system automatically adjusts cooling, humidification, and ventilation functions based on the sensor data to ensure that the environment within the pretreatment chamber 10 is always in the optimal pretreatment state, thereby improving pretreatment efficiency and quality.

[0049] In some embodiments, the Peltier effect is applied to the pretreatment chamber 10 to achieve rapid cooling or heating. For example, during thawing, the temperature can be rapidly increased to melt the ice crystals; when rapid cooling of food is needed for preservation or marinating, the temperature can be rapidly decreased, and temperature control is more precise. A pulsed magnetic field is used to act on the ice crystal structure inside the food, causing the ice crystals to melt rapidly, thereby greatly shortening the thawing time while minimizing damage to the food's cellular structure and preserving its nutrition and texture. This technology can serve as a supplement or alternative to traditional thawing methods and can be applied to the thawing function of the pretreatment chamber 10.

[0050] In pre-treatment processes that require humidification, such as marinating meat or preserving fruits and vegetables, ultrasonic humidification technology can refine water molecules into tiny particles and distribute them evenly within the chamber, providing a suitable humidity environment for the food and preventing the food from losing water and affecting its taste and quality.

[0051] The system integrates multiple pre-processing functions such as defrosting, marinating, preservation, and fermentation into a single compartment or a switchable module. Through a reasonable spatial layout and function switching design, users can easily select and operate according to different ingredients and pre-processing needs, thereby improving the utilization rate and practicality of the compartment.

[0052] In some embodiments, the pre-processing chamber 10 of this application is equipped with combinable and detachable pre-processing accessories, such as racks of different sizes, sealed containers, marinating baskets, etc. Users can freely match and adjust them according to the shape, size and pre-processing method of the ingredients, so that the chamber can better adapt to the requirements of various ingredients and pre-processing processes.

[0053] A dedicated air duct 20 is set up in the pre-processing room 10, equipped with small fans and other devices, so that low-temperature air can be blown more powerfully towards the food in a specific direction, instead of simply relying on natural convection. The air duct 20 allows the airflow to evenly cover all parts of the food, accelerating heat exchange. For example, when defrosting meat, all sides can be blown by cold air at the same time, effectively shortening the defrosting time.

[0054] This application equips the pre-processing chamber 10 with an independent cooling module, which can precisely control parameters such as temperature and airflow in the area. For example, during low-temperature marinating, the temperature can be quickly and accurately adjusted to the most suitable low-temperature range for marinating, while reasonable airflow control allows the marinade and ingredients to blend more fully and quickly, improving marinating efficiency.

[0055] Heating wires or other heating elements are embedded in the pre-treatment compartment 10 to achieve intelligent alternating heating and cooling during food defrosting, in conjunction with the refrigerator's low-temperature environment. First, the outer layer of the food is slowly defrosted at a suitable low temperature to prevent rapid growth of surface microorganisms. Then, the heating function is activated in a timely manner to accelerate internal defrosting. In this way, the quality of the food can be guaranteed while significantly shortening the defrosting time.

[0056] This application utilizes technologies such as image recognition or sensors to enable the refrigerator to automatically identify the types of food placed in the pre-processing compartment 10. Then, based on built-in big data and algorithms, it automatically matches and initiates the most suitable pre-processing program. For example, if it identifies a steak, it automatically sets the optimal temperature, time, and airflow parameters for thawing and marinating, reducing the tedious manual adjustment process for users and improving efficiency. Temperature and humidity sensors are installed in the pre-processing compartment 10 to monitor various parameters in real time. If any deviation from the preset optimal state is detected, it promptly feeds back to the control system, automatically adjusting parameters such as cooling, heating, and airflow to ensure the pre-processing is always highly efficient, guaranteeing timely and high-quality completion of the process.

[0057] The following is an analysis of 10 pairs of different types of ingredients in the pretreatment chambers of this application:

[0058] I. Meat Ingredients

[0059] 1.1 Thawing

[0060] For chunks of red meat such as beef, pork, and lamb, the optimized directional airflow design and intelligent heating-assisted defrosting function work very well. A strong, directional, low-temperature airflow quickly removes the surface coldness of the meat, accelerating heat exchange and allowing the meat to defrost gradually from the outside in. The heating-assisted function intervenes at appropriate stages to further accelerate the melting of internal ice crystals, preventing the meat from being cooked on the outside but raw on the inside, thus efficiently preserving its texture and flavor. For sliced ​​white meat such as chicken and fish, perforated or open shelves with a well-organized layout allow for flat placement, increasing the contact area with cold air. Combined with precise temperature control, defrosting can be completed quickly while minimizing the impact on the meat's tenderness.

[0061] 1.2 Marinating

[0062] Independent cooling and airflow control functions ensure that the marinating chamber can be precisely maintained at a low temperature range suitable for meat marinating. For example, for cured products such as ham and bacon that require long-term low-temperature marinating, it can stably provide a suitable temperature and humidity environment. Through reasonable airflow, the marinade can fully penetrate into the food, improving the marinating effect and efficiency. For fresh steaks and pork chops, the variable temperature zone can quickly switch to a suitable temperature. Combined with the intelligent recognition program, it matches the optimal marinating time and airflow parameters, ensuring that the marinade adheres evenly and speeding up the marinating process.

[0063] II. Fruits and Vegetables

[0064] 2.1 Pre-treatment for preservation

[0065] When performing pre-cooling procedures on fruits and vegetables requiring low-temperature pretreatment, such as pre-cooling freshly picked strawberries, a wide-range variable temperature zone can quickly adjust to a suitable low temperature to prevent them from spoiling too quickly. Dedicated compartments in a zoned layout prevent strawberries from being crushed or bumped together, while good airflow circulation maintains a uniform temperature within the compartments, slowing down spoilage. For long, slender fruits and vegetables such as cucumbers and eggplants, a well-designed shelving system allows them to be arranged neatly, ensuring that cool air surrounds them, extending their shelf life and facilitating further processing or consumption.

[0066] 2.2 Processing aspects such as pickling

[0067] For some pickled fruits and vegetables, such as radishes and green beans, the low-temperature environment precisely controlled by the independent refrigeration module during the pickling pretreatment can inhibit the growth of microorganisms. The intelligent control program automatically sets the appropriate pickling temperature and time according to the type of food, and the reasonable airflow promotes the even distribution of salt and other pickling ingredients, making the pickling process more efficient and the finished product of better quality.

[0068] III. Baking Ingredients

[0069] 3.1 Butter softening

[0070] For butter, a common ingredient in baking, the optimized chamber can precisely control the temperature within the appropriate range for softening butter, such as around 15°C. Gentle airflow circulation ensures that all parts of the butter are heated and softened evenly, preventing localized over-melting. This lays a good foundation for subsequent baking operations such as making cakes and cookies. Moreover, compared to natural convection softening of butter, the time is significantly reduced, and the efficiency is significantly improved.

[0071] 3.2 Regarding the cold fermentation of dough

[0072] During the pretreatment of dough cold fermentation, the variable temperature zone can switch to a low temperature suitable for yeast fermentation. At the same time, the real-time monitoring function ensures that the temperature and humidity of the fermentation environment are stable. The reasonable layout of the zones can accommodate dough containers of different sizes, and the airflow circulation can evenly distribute the temperature throughout the fermentation space, ensuring that the dough ferments fully and evenly, which helps to improve the quality of the baked goods and shorten the overall fermentation time.

[0073] IV. Other ingredients

[0074] When pre-treating dried goods by soaking, the temperature control function of the compartment can maintain the environment at a suitable temperature slightly higher than room temperature, accelerating the absorption of moisture by the dried goods. When pre-treating eggs by braising, precise temperature control and good air circulation can allow the braising liquid to penetrate the eggs better, improving the braising effect and efficiency.

[0075] Overall, the optimized pre-processing compartment 10 of the refrigerator, through the coordinated use of multiple functions, can better adapt to the needs of different types of food in different pre-processing processes, improve the efficiency and quality of pre-processing, and provide users with a more convenient and efficient experience in the food processing stage.

[0076] Thawing tests were conducted on common food items (such as beef, chicken, fish, and shrimp) of different types (e.g., chunks, slices), weights, and initial freezing states). The time spent thawing using natural convection before optimization and thawing using the newly designed compartments after optimization was recorded, and the percentage reduction in time was calculated. For example, thawing 1 kg of beef originally took 3 hours, but after optimization, it only took 1.5 hours, meaning a 50% reduction in thawing time, demonstrating the improvement in thawing efficiency.

[0077] For the curing process, samples were taken from different parts of the food after curing to analyze the differences in the content of the curing ingredients, thus assessing the uniformity of curing. For example, after curing ham, the content of salt, spices, and other components on the surface and inside was tested to see if they were evenly distributed. The time spent curing different foods (such as radishes and steaks) was recorded, and the changes in time before and after optimization were compared. The average curing time was shortened by a certain percentage after optimization, indicating a positive effect on curing efficiency.

[0078] The application provides a large-size, high-definition visual operation interface, which allows users to intuitively see the status of ingredients, pre-processing progress, setting parameters, and other information in the room. At the same time, the user can operate the system through touch screen or voice control, making the operation simpler, more convenient, and more user-friendly.

[0079] The refrigerator with a pre-processing compartment provided in this application controls the air intake in the drawer by adjusting the fan speed to meet the airflow requirements in different scenarios. The fan is installed outside the drawer, and the airflow in the cavity is accelerated by the fan to meet the needs of drying and defrosting food. The bottom of the drawer is designed with a wavy line to ensure air circulation at the bottom.

[0080] Example 1:

[0081] When the user selects the aging function, the air duct 20 delivers cold air, raising the temperature of drawer 110 to the first set temperature T1 (-5 to 4°C). Simultaneously, the sterilization device 210 intermittently activates to kill microorganisms carried in the air within the air duct 20. The fan assembly 111 activates, operating at a first speed R1 (2500 to 3000 r / min), allowing air to enter drawer 110 through the ventilation grille 113 and achieving an internal airflow velocity of 1.5 to 2 m / s. After running for a first set time t1 (0 to 5 days), the fan assembly 111 operates at a second speed R2 (1500 to 2000 r / min), achieving an internal airflow velocity of 0.5 to 1 m / s. After running for a second set time t2 (0 to 3 days), the fan assembly 111 shuts off, keeping the aging food moist and preventing excessively rapid drying that could cause the meat to become dry and hard. After the humidification time reaches the third set time t3 (0~2d), the fan assembly 111 is turned on again. The fan assembly 111 operates at a speed of R2 and runs for the second set time before humidification is performed again. This cycle continues until the fourth set time t4 (14~28d) is reached, at which point the curing is considered complete.

[0082] Example 2:

[0083] When the user selects the defrost function, the air duct 20 delivers cold air, raising the temperature of drawer 110 to the second set temperature T2 (0-4℃). Simultaneously, the sterilization device 210 intermittently activates to kill microorganisms carried in the air duct 20. The fan assembly 111 activates, operating at the third speed R3 (3000-4000 r / min), allowing air to enter drawer 110 through the ventilation grille 113, achieving a cavity air velocity of 2-2.5 m / s. The defrosting process is considered complete when the fifth set time t5 (0.5h-2h) is reached.

[0084] Example 3:

[0085] When the user selects the meat storage function, the air duct 20 delivers cold air, causing the temperature of the pre-processing chamber 10 to reach the third set temperature T3 (-3 to 0℃), and the sterilization device 210 is turned on intermittently. The fan assembly 111 does not work.

[0086] Compared to thawed chicken, chicken before pretreatment may have a whitish surface, loose texture, and significant blood seepage. After pretreatment, the chicken retains its normal color, maintains a certain degree of elasticity, and shows a significant reduction in blood seepage, indicating that the pretreatment room better protects the quality of the ingredients. For fruits and vegetables, examining their freshness and nutrient retention, and analyzing changes in the content of nutrients such as vitamin C before and after pretreatment using professional testing methods, helps maintain the quality of fruits and vegetables.

[0087] Examine the performance of pre-treated ingredients in subsequent cooking and processing stages. For example, marinated ingredients absorb flavors better and present a more ideal taste during cooking; fermented dough produces baked goods with better texture and fluffier texture. By analyzing the quality feedback of the final product, we can demonstrate that the design of the pre-treatment room has a significant effect on improving the quality of ingredient pre-treatment.

[0088] This application provides a refrigerator with a pre-processing compartment, which is located within the refrigerator's crisper compartment. The pre-processing compartment includes a drawer and a fan assembly, with the fan assembly positioned outside the drawer. Air outlets are located on both sides of the drawer, and a top cover is provided on the top of the drawer. This application controls the airflow inside the drawer by adjusting the fan assembly's rotation speed to meet the airflow requirements in different scenarios. By installing the fan assembly outside the drawer, the airflow within the cavity is accelerated, fulfilling the needs for drying and defrosting food. The drawer bottom is designed with a wavy, raised design to ensure proper airflow. The refrigerator with a pre-processing compartment provided by this application can quickly defrost and also dry / cook food, meeting the needs of users in various scenarios.
