Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator. Background Technology

[0002] Refrigerators are used to store items and extend their shelf life, making them an indispensable home appliance in modern households. Currently, refrigerators not only serve as the primary storage appliance for food but also perform certain food processing functions, such as marinating.

[0003] Existing technologies typically use a vacuum environment to accelerate the marinating of food and a magnetic field to preserve it. This is because a vacuum creates a negative pressure environment, increasing the internal pores of the food, which facilitates the penetration of the marinade. Maintaining negative pressure for a period of time allows the marinade to contact the food more thoroughly and evenly. Furthermore, since water, enzymes, proteins, and other substances within the food are diamagnetic and move randomly, adding a magnetic field enhances the orderly movement of these substances, slowing down the food's metabolism and physiological and biochemical reaction rates, thus extending its shelf life.

[0004] However, existing refrigerators add magnetic field devices to the entire vacuum drawer to improve the preservation of fresh fruit. However, the effect of magnetic field inhibiting the activity of antimagnetic substances such as moisture conflicts with the effect of vacuum accelerating marinating, which will affect the effect of accelerated marinating and storage preservation. Furthermore, the existing refrigerator marinating and storage methods for food are still based on the premise that accelerated marinating and storage preservation interfere with each other.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] In view of the problems pointed out in the background art, this utility model proposes a refrigerator that can improve the preservation and storage effect of food.

[0007] The objective of this application is achieved through the following technical solution:

[0008] A refrigerator is provided, including a cabinet, an inner liner disposed inside the cabinet, the inner liner forming a receiving cavity with a front opening, a door rotatably disposed on the cabinet for opening and closing the receiving cavity; a vacuum drawer disposed inside the receiving cavity, a vacuum environment being formed inside the vacuum drawer, and a pickling zone being formed inside the vacuum drawer; a magnetic component is configured to generate a magnetic field within the pickling zone; and a first magnetic field shielding device is configured to isolate the pickling zone from the magnetic field.

[0009] Beneficial effects: The marinating zone is built into a vacuum drawer, utilizing the vacuum environment to accelerate the marinating process. After marinating, the food is stored in the marinating zone, where the vacuum environment extends its shelf life.

[0010] When the ingredients in the marinating area are marinated, the first magnetic field shielding device is used to isolate the marinating area from the magnetic field. The magnetic field generated by the magnetic components cannot act on the marinating area, and there is no magnetic field in the marinating area, thus avoiding interference from the magnetic field to the marinating process.

[0011] After marinating, the first magnetic field shielding device removes the magnetic field shielding from the marinating area. The magnetic field generated by the magnetic components then acts on the marinating area, creating a magnetic field within it. This magnetic field enhances the orderly movement of water and other substances within the food, slows down the food's metabolism and physiological and biochemical reaction rates, and extends its shelf life.

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Therefore, they should not be construed as limitations on this application.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Refrigerators are a common household appliance and are now widely used. Users can store food in refrigerators to prevent it from spoiling.

[0032] like Figure 1 , 2 As shown, in this embodiment, the refrigerator includes a cabinet 1 and an inner liner 2.

[0033] The cabinet 1 forms the overall appearance of the refrigerator. Cabinet 1 is roughly rectangular frame-shaped. The top and bottom of cabinet 1 are opposite ends, and the height of cabinet 1 is measured from the top to the bottom. The left and right sides of cabinet 1 are opposite sides, and the width of cabinet 1 is measured from the left to the right. The front and rear sides of cabinet 1 are opposite sides, and the thickness of cabinet 1 is measured from the front to the rear. The inner liner 2 is located inside cabinet 1.

[0034] The inner liner 2 has a refrigerator compartment inside, which is used to place items. The refrigerator compartment has an opening facing the front of the cabinet 1. The refrigerator compartment can be in a refrigerated temperature environment, a frozen temperature environment, or a normal temperature environment. A door 3 is provided at the opening of the compartment. The door 3 is a straight plate located on the front of the cabinet 1 and is connected to the cabinet 1 in an openable and closable manner to open or close the refrigerator compartment.

[0035] Understandably, a refrigerator also includes a refrigeration system and an air supply system. The refrigeration system is installed inside the cabinet 1 and is used to provide cold air to the refrigerator compartment. The refrigeration system typically refers to a closed system composed of components such as a compressor, evaporator, condenser, dryer filter, return pipe, and throttling device, as well as refrigerant. Each component is distributed in different locations within the cabinet 1 according to its structural characteristics to meet its corresponding functional requirements. The working process of the refrigeration system mainly includes compression, condensation, throttling, and evaporation. The compression process is as follows: After the refrigerator's power cord is plugged in, with the thermostat contacts closed, the compressor starts working. The low-temperature, low-pressure refrigerant from the evaporator is drawn into the compressor and compressed into high-temperature, high-pressure refrigerant gas before being discharged into the condenser. The condensation process is as follows: The high-temperature, high-pressure refrigerant gas exchanges heat with the external environment through the condenser, its temperature decreases, and it is gradually cooled into room-temperature, high-pressure saturated refrigerant vapor, and then further cooled into saturated refrigerant liquid. The throttling process is as follows: The condensed saturated liquid refrigerant is filtered through a dryer to remove moisture and impurities before flowing into the throttling device. The device reduces pressure and transforms the refrigerant into low-pressure, room-temperature wet vapor. The evaporation process: This low-pressure, room-temperature wet vapor enters the evaporator, absorbs heat, and vaporizes, lowering the temperature of the evaporator and its surroundings, thus achieving refrigeration. This process also transforms the refrigerant into a low-temperature, low-pressure gas. The refrigerant exiting the evaporator returns to the compressor, repeating the above process. Through the change in the refrigerant's state, energy is converted, transferring heat from inside the refrigerator to the outside air, thereby achieving the refrigerator's refrigeration cycle.

[0036] An air supply system is installed inside the housing 1 to power the flow of cold air. The air supply system generally includes a fan and a guide channel. In some embodiments, the air inlet of the guide channel is located close to the fan, and the air outlet is located away from the fan; in other embodiments, the air outlet is located close to the fan, and the air inlet is located away from the fan. The fan drives the air within the guide channel. An evaporator is correspondingly installed within the guide channel. The cold air, cooled by the evaporator, flows along the guide channel driven by the fan. The cold air passes through the installation space formed between the inner liner 2 and the housing 1, and finally enters the refrigerator compartment to perform refrigeration.

[0037] Based on the above structure, such as Figures 1-8 As shown, this application proposes a refrigerator, including: a cabinet 1, an inner liner 2, a door 3, a vacuum drawer 4, and a magnetic component 5.

[0038] The inner liner 2 is installed in the box body 1, and the inner liner 2 has a front opening for receiving cavity 21. The door 3 is rotatably installed in the box body 1 and is used to open and close the receiving cavity 21.

[0039] The vacuum drawer 4 is installed inside the receiving cavity 21, and a vacuum environment can be formed inside the vacuum drawer 4.

[0040] The magnetic component 5 is installed on the vacuum drawer 4 to form a magnetic field inside the vacuum drawer 4.

[0041] The vacuum drawer 4 includes: a fixed part 41, a pull-out part 42, a partition plate 43, and a first magnetic field shielding device 44.

[0042] The fixing part 41 is installed inside the receiving cavity 21 and the front end of the fixing part 41 is open.

[0043] The pull-out part 42 is inserted into the front opening of the fixing part 41 and can be slidably installed in the fixing part 41. The pull-out part 42 has a storage cavity 45 with a top opening.

[0044] The partition plate 43 is installed inside the storage cavity 45 to divide the storage cavity 45 into a storage area 451 and a marinating area 452. The first magnetic field shielding device 44 is installed in the marinating area 452 to block the magnetic field from entering the marinating area 452, so that there is no magnetic field inside the marinating area 452.

[0045] Based on the above technical solution, the vacuum drawer 4 of this application can form a vacuum environment, and the magnetic component 5 provided on the vacuum drawer 4 can form a magnetic field inside the vacuum drawer 4. The space of the vacuum drawer 4 is divided into a storage area 451 and a marinating area 452 by the partition plate 43, and a first magnetic field shielding device 44 is provided in the marinating area 452, so that the storage area 451 forms a vacuum + magnetic field environment, and the marinating area 452 forms a vacuum environment, thereby enhancing the preservation effect of the storage area 451 and avoiding interference of the magnetic field on vacuum marinating.

[0046] It should be noted that there are several ways to install partition panel 43:

[0047] The vacuum drawer 4 can be vertically divided into two areas: left and right, or front and back. One area is for marinating (452), and the other is for storage (451). The marinating area 452 has a vacuum but no magnetic field, while the storage area 451 has both a vacuum and a magnetic field. The vertical partition is installed in a recessed, plug-in configuration within the 1 / 4 to 3 / 4 section of the drawer's left / right or front / back section, dividing the drawer's capacity into a 1:3 to 3:1 ratio. Due to the different installation positions, the effective distance between the magnetic field device and the vacuum drawer 4 increases, requiring adjustment of the magnetic field strength. For every 5cm increase, the magnetic field strength needs to be increased by 20%-50%.

[0048] The drawer can be horizontally divided into upper and lower sections, with physical separation on both sides. The partition is movable, allowing for free access from both sides and sliding / folding based on the drawer, facilitating storage of food in the lower section. Supports are installed on both side walls of the drawer, with the support height ranging from 1 / 5 to 4 / 5 of the drawer's height. These supports divide the volume of the upper and lower sections into a ratio of 1:4 to 4:1.

[0049] In addition, when the partition 43 is divided into left and right sections, the left side of the drawer is the marinating area 452 and the right side is the storage area 451; when the partition 43 is divided into front and back sections, the front of the drawer is the marinating area 452 and the back is the storage area 451; when the partition 43 is divided into upper and lower sections, the lower part of the drawer is the marinating area 452 and the upper part is the storage area 451.

[0050] In some embodiments of this application, a controller is also included, configured to: determine the marinating time of the ingredients based on their weight; and control the ingredients to marinate when the vacuum level of the vacuum drawer 4 reaches a preset value. The controller inside the refrigerator can automatically determine the marinating time of the ingredients based on their weight and control the ingredients to marinate when the vacuum level of the drawer reaches a preset value, making it convenient to use.

[0051] Specifically, the controller is also configured to: control the vacuum level and temperature of the marinating and / or storage of the ingredients according to the type of ingredients; obtain the moisture content of the marinated ingredients; and adjust the magnetic field strength of the vacuum drawer 4 according to the moisture content. Since different ingredients have different suitable environments, adjusting the vacuum level, temperature, and magnetic field strength according to the type of ingredients can effectively improve the storage effect, increase the storage time, and reduce the marinating time.

[0052] In some embodiments of this application, such as Figure 7 As shown, the vacuum drawer 4 is equipped with a weight recognition device 6 for detecting the weight of food ingredients. The weight recognition device 6 is electrically connected to the controller and is located on the bottom surface of the vacuum drawer 4. The weight recognition device 6 can automatically measure the weight of the food ingredients after they are placed inside, improving the automation level of the refrigerator marinating process.

[0053] In some embodiments of this application, such as Figure 7 As shown, the vacuum drawer 4 is equipped with a camera component 7, which is used to obtain the type of food and / or the moisture content of the food in the vacuum drawer 4. The camera component 7 is electrically connected to the controller and is installed on the top of the vacuum drawer 4, specifically the top of the fixing part 41.

[0054] The camera component 7 can identify the type of food and provide feedback to the controller to adjust the temperature setting and vacuum level of the drawer.

[0055] Furthermore, the moisture sensing component in camera assembly 7 identifies the moisture content in the food and feeds it back to the controller to adjust the magnetic field strength in the area.

[0056] The camera component 7 can rotate at a certain angle, ranging from 0° to 90° vertically and 360° horizontally, thus enabling a comprehensive scan of the food inside the vacuum drawer 4. The food moisture content identification device can be the camera component 7, such as near-infrared spectroscopy, which identifies the moisture content of the food through spectral imaging; or it can be a moisture sensor that identifies the moisture content of the food through capacitance monitoring. The moisture content of common foods is shown in Table 1.

[0057] Table 1

[0058]

[0059] In some embodiments of this application, such as Figure 9 As shown, the vacuum drawer 4 further includes a second magnetic field shielding device 46, which surrounds the outer periphery of the fixing part 41, and the magnetic element 5 is located inside the second magnetic field shielding device 46. The second magnetic field shielding device 46 can be installed on the outer periphery of the vacuum drawer 4, and the magnetic element 5 can be installed inside the second magnetic field shielding device 46 to prevent the magnetic field from leaking outward. The second magnetic field shielding device 46 is preferably fixed and non-removable to ensure the stability of its structure.

[0060] In some embodiments of this application, such as Figure 3 , Figure 4 As shown, the fixing part 41 includes an upper cover plate 411, a vacuum bucket 412, and a lower cover plate 413 installed sequentially from top to bottom on the receiving cavity 21, and a control panel 414 installed on the front side of the upper cover plate 411. The control panel 414 is electrically connected to the vacuum bucket 412, which has an opening at the front end. The pull-out part 42 is inserted into the opening at the front end of the vacuum bucket 412 and can slide back and forth on the vacuum bucket 412. The control panel 414 integrates a controller. The control panel 414 is preferably installed at the front end of the upper cover plate 411 in a bayonet manner. The vacuum drawer 4's settings, magnetic device, camera, moisture sensor, refrigeration, etc., are all controlled by the controller. The control panel 414 can be set with different settings such as fruit and vegetable, fresh food, and smart settings according to the basic types of food stored in the vacuum drawer 4. In addition, a space is defined between the upper cover plate 411 and the lower cover plate 413 for the vacuum drum 412 to be placed therein. The control panel 414 can control the environment inside the vacuum drum 412 to make the environment of the vacuum drum 412 reach a better state. The front end of the vacuum drum 412 is open, so that the pull-out part 42 can be slidably installed in the vacuum drum 412 to realize the basic function of the drawer.

[0061] In addition, refer to Figure 3, Figure 4 , Figure 7 Based on an existing vacuum refrigerator, a magnetic field generating device, namely a magnetic component 5, is added to the top and bottom, left and right, or front and back of the vacuum drum 412. The magnetic component 5 can be any one of a magnetic sheet, an electromagnetic coil, or a magnet, and there must be at least one magnetic component 5. If it is a single magnetic component 5, it can be on one side of the vacuum drawer 4, taking the magnetic component 5 located at the top or bottom of the vacuum drawer 4 as an example. When the magnetic component 5 is in the upper part of the vacuum drawer 4, it can be on the inner or outer wall of the top of the vacuum drum 412; it can also be in the air duct assembly of the vacuum drawer 4; when it is on the air duct assembly of the vacuum drawer 4, it can be on the inner or outer wall of the air duct assembly cover plate 415, or on the upper or lower layer of the air duct foam 416; it can also be on the inner or outer wall of the upper cover plate 411; or it can be on the bottom of the upper drawer of the vacuum drawer 4, or on the inner or outer wall of the bottom partition. When the magnetic component 5 is located at the bottom of the vacuum drawer 4, it can be on the inner or outer wall of the bottom of the vacuum barrel 412; it can also be on the inner or outer wall of the bottom of the vacuum drawer 4; it can also be on the inner or outer wall of the bottom of the inner liner 2 of the corresponding cabinet 1 of the vacuum drawer 4; it can also be installed on the inner or outer wall of the top cover of the lower drawer of the vacuum drawer 4; or it can be installed on the inner or outer wall of the partition inside the vacuum drawer 4, or in the inner layer of the partition. Depending on the type of magnetic component 5, the installation method can be adhesive, screw, or clip fixing; when the magnetic component 5 is on the inner liner 2 of the cabinet 1, the installation method also relies on foaming. At this time, the surface tension of the side of the magnetic component 5 in contact with the foam material must be ≥38N / m to prevent air bubbles from being generated during the foaming process, which would cause the inner liner 2 to bulge.

[0062] If there are two magnetic components 5, either one can be installed in the same position and manner as the single magnetic component 5 described above. However, both magnetic components 5 must be placed parallel to each other, with the N and S poles facing each other. The magnetic component 5 should be at a 90° angle to the removable partition 43 inside the vacuum drawer 4, so that the pickling zone 452 can be shielded from external magnetic fields by the shielding device, while the magnetic field of the storage zone 451 remains undisturbed. The magnetic field shielding device can be a magnetic shielding agent coating, a magnetic shielding cover, etc., and can be located inside or outside the pickling zone 452.

[0063] In some embodiments of this application, such as Figure 5 , Figure 6As shown, the vacuum drawer 4 also includes a slide rail 47, which is mounted on the pull-out portion 42. The first magnetic field shielding device 44 is slidably mounted on the slide rail 47. The marinating area 452 requires magnetic field shielding; therefore, a first magnetic field shielding device 44 is installed inside the marinating area 452 to block the magnetic field from entering the marinating area 452. However, since the fixing part 41 and the pull-out portion 42 are separate, it is difficult to cover the entire marinating area 452 with the first magnetic field shielding device. Furthermore, it is necessary to consider how to design the first magnetic shielding device to cover the entire marinating area 452 while maintaining a simple structure. Therefore, the first magnetic field shielding device 44 includes a magnetic field shielding cover, which can slide on the slide rail 47 and is fixed in position on the slide rail 47 by a magnetic attraction limiting device. Taking the vertically arranged partition plate 43 as an example, the first magnetic field shielding device 44 includes a magnetic field shielding cover, which includes a top plate and side plates located on opposite sides of the top plate. These two side plates are located on different sides from the partition plate 43. The first magnetic field shielding device 44 also includes the vertically arranged partition plate 43 with magnetic shielding material, and the magnetic shielding material is only provided on the side closest to the pickling area 452, so as not to affect the magnetic field distribution of the storage area 451. The side plate of the pickling area 452 opposite to the partition plate 43 is also provided with magnetic shielding material. The first magnetic field shielding device 44 also includes a superconducting plate located at the bottom of the pickling area 452, and the superconducting plate is provided with magnetic shielding material. Therefore, the above-mentioned first magnetic field shielding device 44 includes 6 magnetic shielding surfaces, and the magnetic field shielding cover, partition plate 43, side plates and bottom plate of the pickling area 452 are all detachable, which is convenient for users and also facilitates the use of the vacuum drawer 4.

[0064] When pickling is not required, the first magnetic field shielding device 44 is removed, and the entire vacuum drawer is set up as storage area 451. When pickling is required, the first magnetic field shielding device 44 is installed to accelerate the pickling process.

[0065] The first magnetic field shielding device 44 can also be installed as a whole in the front or back of the drawer. In this case, any area where the first magnetic field shielding device 44 is installed can be used as the pickling area 452.

[0066] In some embodiments of this application, such as Figure 10 As shown, in order to improve the preservation effect, a sterilization and deodorization device 8 can be installed in the storage area 451, such as a passive sterilization and deodorization device 8 such as a catalyst block or activated carbon, or an active sterilization and deodorization device 8 such as an ion module or a photo-sterilization module.

[0067] This application also provides a method for controlling the marinating and storage of food in a refrigerator, comprising the following steps: determining the marinating time based on the weight of the food; and controlling the marinating process when the vacuum level of the vacuum drawer 4 reaches a preset value. Using the vacuum drawer 4 of this refrigerator for marinating significantly reduces the marinating time and automatically determines the marinating time based on the weight of the food, starting marinating when the vacuum level reaches the preset value, saving time and providing convenient operation.

[0068] In some embodiments of this application, before the step of controlling the marinating time of the ingredients according to their weight, the method further includes: establishing a preset correspondence between the weight of the ingredients and the marinating time; obtaining the marinating scenario of the ingredients; and determining the corresponding weight of the ingredients according to different marinating scenarios.

[0069] To further automate marinating in refrigerators, based on previous research data, the weight of ingredients can be correlated with marinating time. This data can be input into the refrigerator, and when the refrigerator receives the weight of the ingredients, it can automatically indicate the marinating time. In addition, the refrigerator can also identify the weight of ingredients according to different marinating scenarios, making the marinating time more accurate.

[0070] Specifically, the pickling scenarios include containerless scenarios, standard container scenarios, and other container scenarios.

[0071] When the marinating scenario is without a container, the weight m1 of the food is obtained, and the marinating time is controlled to be T1. The weight m1 of the food is detected by the weight recognition device 6 inside the vacuum drawer 4.

[0072] When the marinating scenario is a standard container, the weight of the ingredients m2 is calculated, and the marinating time is controlled to be T2. m2 satisfies: m2=m2'-m0, where m2' is the total weight of the standard container and the ingredients, and m0 is the weight of the standard container in the refrigerator.

[0073] When the marinating scenario is in another container, the weight of the ingredients m3 is obtained, and the marinating time is controlled to T3, wherein the weight of the ingredients m3 is manually input by the user.

[0074] Depending on the type of pickling container, the weight of the ingredients can be identified in three different ways: no container, standard container, and other container scenarios. The weight of the ingredients can be obtained based on the different scenarios, thus leading to a more accurate pickling time.

[0075] For cases involving only food marinating: based on the weight m1 of the marinated food and according to data from previous studies, the marinating time T1 is automatically indicated, which is defined as the first type of marinated food, and the marinating container is defined as "no container".

[0076] For marinating using the refrigerator's built-in standard vacuum jars (boxes) and vacuum bags: The marinating time is determined based on weight differences. First, the user selects whether to use a vacuum jar or a vacuum bag. Then, the weight of the container and food (m2') is weighed, and the weight of the container itself (m0) is automatically subtracted to obtain the net weight of the food (m2). Based on preliminary research data, the marinating time (T2) is automatically indicated. The weight of the container itself is the weight of the internal product and can be pre-entered into the database. The weight of the marinating container itself (m0) is defined as the second type of marinated food, and the marinating container is defined as a "standard container."

[0077] For pickling using other pickling containers: An input interface will be set up on the screen or app, allowing users to select the net weight of the ingredients to be pickled, such as 0-1000g, with 50g increments corresponding to different pickling times. The screen or app will notify the user upon completion of pickling. The net weight of this type of ingredient is m3, defined as Category 3 pickled ingredients, and based on preliminary research data, the pickling time T2 will be automatically indicated. The pickling container is defined as "Other Containers".

[0078] In some embodiments of this application, the weight of the ingredients ranges from 200g to 500g, corresponding to a marinating time range of 10min to 25min. Furthermore, for every 50g increase in ingredient weight, the marinating time increases by 1min to 3min. By adopting the above-mentioned correspondence between ingredient weight and marinating time, marinating of ingredients can be achieved more quickly and comprehensively, automatically and reliably completing the marinating of ingredients of different weights.

[0079] In some embodiments of this application, the following steps are also included: receiving an instruction to add new ingredients, determining the marinating status of the pre-prepared ingredients, and controlling the marinating time of the pre-prepared ingredients and the new ingredients according to the marinating status of the pre-prepared ingredients.

[0080] When the marinating state of the previous ingredient is not yet complete, the marinating time of the previous ingredient is paused when the new ingredient is added. After the new ingredient is added, the marinating time of the new ingredient is obtained. When the vacuum degree of the vacuum drawer 4 reaches the preset value, the marinating time of the previous ingredient is resumed, and the marinating time of the new ingredient is started.

[0081] When the marinating state of the previous ingredient is complete, the previous ingredient is removed while adding new ingredients. After adding new ingredients, the marinating time of the new ingredients is obtained. When the vacuum degree of the vacuum drawer 4 reaches the preset value, the marinating time of the new ingredients is controlled to start timing.

[0082] In the marinating process, besides placing the ingredients into an empty marinating area 452, the following situations also exist: when the first ingredient is being marinated, a second or third marinating ingredient is added.

[0083] At this point, based on the above basic marinating method, segmented timing is set on the screen or APP (displaying marinating time and remaining marinating time respectively, so that users can understand the specific information of each ingredient verification and receive a reminder when marinating is complete).

[0084] Specifically: (1) For the first marinated ingredient, if the second ingredient is put in during the marinating process, the marinating time of the first ingredient will be paused when the door is opened. After the second ingredient is put in and the door is closed, the vacuum is turned on and the vacuum level reaches the preset value. The marinating time of the first ingredient will continue to be counted until the marinating is completed.

[0085] (2) For the second ingredient, after the second ingredient is put in and the door is closed, the vacuum is turned on and the vacuum level reaches the preset value. The timing starts when the door is opened and the vacuum level reaches the preset value. If the door is opened and the process is interrupted, proceed according to (1). If there is no interruption, the timing is based on the basic logic until the marinating is completed.

[0086] (3) If there are 3rd, 4th, 5th and more ingredients, follow the same method.

[0087] Furthermore, considering different container scenarios, a common implementation method is described: (1) When the first ingredient is placed in a containerless scenario, the pickling container is selected as "none". The weight recognition device 6 directly weighs the weight m1, outputs the pickling time T1 of the first ingredient, and starts vacuuming after the door is closed. When the vacuum level reaches the preset value, the timing automatically starts the pickling timer; (2) When the first ingredient is pickling, the door is opened and the second ingredient in a standard container scenario is placed in, and the pickling time of the first ingredient is paused. When the user puts in the second ingredient, the pickling container is selected as "standard". After the ingredient is placed in the drawer, the weight sensor weighs the weight m2'. The difference between m2'-m1-m0 is used as the net weight m2 of the second ingredient. The pickling time of the second type of pickled ingredient is calculated based on the net weight. The timing starts when the drawer is closed until the vacuum level reaches the preset value. At the same time, the timing of the first type of pickled ingredient continues until the pickling is completed. (3) For the first and second categories of ingredients, when adding ingredients using other containers during the marinating process, the user selects "Other" as the marinating container and inputs the weight m3 of the third category of marinated ingredients. Then m3 is the net weight of that category of ingredients. The marinating timer starts when the vacuum level reaches the preset value after the door is closed, and a notification is given upon completion. (4) During the marinating process, if the first category of marinated ingredients is finished and the user opens the door to remove the ingredients, and no new marinated ingredients are added, the marinating timer for other ingredients continues when the vacuum level reaches the preset value after the door is closed. (5) If the user opens the door to remove the finished marinated ingredients and then adds new marinated ingredients, the marinating program for the new marinated ingredients must be run according to the above process for adding new ingredients. Existing marinated ingredients will continue to be marinated after the vacuum level reaches the preset value. (The weight sensor only works after the ingredients are added. Since there is no need to add a new marinating action for the ingredients that have been marinated and then removed, the net weight of the ingredients does not need to be identified.)

[0088] In some embodiments of this application, the following step is also included: controlling the vacuum level and temperature of the marinating and / or storage of the ingredients according to the type of ingredients. Since different ingredients have different optimal vacuum levels and optimal temperatures, the vacuum level and temperature inside the vacuum drawer 4 can be controlled to increase storage time and reduce marinating time.

[0089] Specifically, the food ingredients are fruits and vegetables, fresh meat, or other types. When the food ingredients are fruits and vegetables, the vacuum level of the vacuum drawer 4 is controlled at 750 hpa-850 hpa, and the temperature of the vacuum drawer 4 is controlled at 2℃-8℃. When the food ingredients are fresh meat, the vacuum level of the vacuum drawer 4 is controlled at 650 hpa-750 hpa, and the temperature of the vacuum drawer 4 is controlled at -5℃-0℃. When the food ingredients are other types, the vacuum level of the vacuum drawer 4 is controlled at 700 hpa-800 hpa, and the temperature of the vacuum drawer 4 is controlled at 0℃-2℃.

[0090] Since different ingredients have different requirements for vacuum levels and storage temperatures, different vacuum levels can be set according to the type of ingredients. Using the above method, the marinating speed of the same ingredients can be shortened by 2-3 times compared to ordinary marinating, and the storage time can also be greatly increased.

[0091] More specifically, when the types of ingredients in the storage area 451 and the marinating area 452 are different, the temperature of the vacuum drawer 4 is controlled to be a suitable temperature for storing the ingredients in the storage area 451. When the marinating area 452 is working, the vacuum level of the vacuum drawer 4 is controlled to be a suitable vacuum level for the operation of the marinating area 452. When the marinating area 452 is not working, the vacuum level of the vacuum drawer 4 is controlled to be a suitable vacuum level for storing the ingredients in the storage area 451.

[0092] Temperature has a significant impact on storage, while vacuum level has a significant impact on marinating. Therefore, when the types of ingredients in storage zone 451 and marinating zone 452 are different, priority should be given to ensuring the temperature of the ingredients in storage zone 451 and the vacuum level in marinating zone 452, so as to balance the storage and marinating of the ingredients.

[0093] More specifically, when the types of food in storage area 451 are different, the temperature of vacuum drawer 4 is controlled to the storage temperature of the food with the relatively higher optimal storage temperature. The temperature selection of storage area 451 needs to be determined based on the types of food stored in storage area 451. Generally speaking, foods with higher storage temperatures, such as fruits and vegetables, have higher temperature requirements than fresh produce. Therefore, when the types of food in storage area 451 are different, it is preferable to determine the storage temperature based on the food with the relatively higher optimal storage temperature. For example, if storage area 451 stores fruits and vegetables and marinating area 452 stores beef, then the temperature of vacuum drawer 4 is adjusted to 2-8℃ to meet the storage conditions required for fruits and vegetables. When the marinating function is turned on, the vacuum degree in vacuum drawer 4 is 650-750 hpa, and when the marinating process is completed, the vacuum degree is adjusted to 750-850 hpa.

[0094] Specifically, the process also includes the following steps: obtaining the moisture content of the food and adjusting the magnetic field strength of the vacuum drawer 4 according to the moisture content. Since moisture content is a crucial factor in magnetic field preservation, different types of food have different moisture contents, and therefore require different optimal magnetic field strengths. Thus, the magnetic field strength needs to be adjusted according to the type of food to extend storage time.

[0095] More specifically, when the moisture content of the food is 0%-30%, the magnetic field strength inside the vacuum drawer 4 is controlled at 8mT-10mT; when the moisture content is 30%-50%, the magnetic field strength is controlled at 6mT-8mT; when the moisture content is 50%-70%, the magnetic field strength is controlled at 4mT-6mT; when the moisture content is 70%-90%, the magnetic field strength is controlled at 2mT-4mT; and when the moisture content is >90%, the magnetic field strength is controlled at 0mT-2mT. Controlling the magnetic field inside the vacuum drawer 4 in this way can further extend the storage time of the food.

[0096] In summary, the refrigerator and food marinating and storage control method of this application can create a vacuum environment in the vacuum drawer 4, and the magnetic component 5 installed on the vacuum drawer 4 can generate a magnetic field inside the vacuum drawer 4. The space of the vacuum drawer 4 is divided into a storage area 451 and a marinating area 452 by the partition plate 43, and a first magnetic field shielding device 44 is installed in the marinating area 452, so that the storage area 451 forms a vacuum + magnetic field environment, and the marinating area 452 forms a vacuum environment, thereby enhancing the preservation effect of the storage area 451 and avoiding interference of the magnetic field on vacuum marinating. When marinating with the vacuum drawer 4 of this refrigerator, the marinating time of the food can be significantly reduced, and the marinating time of the food can be automatically calculated according to the weight of the food. Marinating starts when the vacuum degree reaches the preset value, saving time and making the operation convenient.

[0097] In some embodiments of this application, a marinating zone 452 is formed inside the vacuum drawer 4, and the marinating zone 452 is configured for vacuum marinating and storing food ingredients. In other words, the marinating zone 452 is built into the vacuum drawer 4, utilizing the vacuum environment to accelerate the marinating of the food ingredients. After marinating, the food ingredients are stored in the marinating zone 452, utilizing the vacuum environment to extend the preservation time.

[0098] The magnetic component 5 is configured to create a magnetic field within the pickling zone 452.

[0099] The first magnetic field shielding device 44 is configured to isolate the marinating zone 452 from the magnetic field when the food is marinated in the marinating zone 452.

[0100] The first magnetic field shielding device 44 is also configured to remove the magnetic field shielding of the marinating zone 452 after the food in the marinating zone 452 has been marinated.

[0101] In other words, when the ingredients in the marinating zone 452 are marinated, the first magnetic field shielding device 44 is used to isolate the marinating zone 452 from the magnetic field. The magnetic field generated by the magnetic component 5 cannot act on the marinating zone 452, and there is no magnetic field in the marinating zone 452, thus avoiding interference from the magnetic field to the marinating process.

[0102] After marinating, the first magnetic field shielding device 44 releases the magnetic field shielding of the marinating zone 452, and the magnetic field generated by the magnetic component 5 acts on the marinating zone 452, thus creating a magnetic field within the marinating zone 452. The magnetic field enhances the orderly movement of substances such as water within the food, slows down the metabolism and physiological and biochemical reaction rate of the food, and extends the shelf life.

[0103] In some embodiments of this application, a storage area 451 is further formed inside the vacuum drawer 4, and the storage area 451 is configured to vacuum preserve food. The magnetic component 5 is configured to create a magnetic field within the storage area 451 and the marinating area 452.

[0104] In other words, the vacuum drawer 4 is equipped with a storage area 451 and a marinating area 452 to meet the different storage needs of ingredients. Ingredients in both storage area 451 and marinating area 452 can utilize the magnetic field generated by the magnetic component 5 to extend their shelf life. However, when ingredients in marinating area 452 are being marinated, there is no magnetic field in marinating area 452 to avoid interference with the marinating process. At this time, storage area 451 still has a magnetic field. Therefore, marinating area 452 and storage area 451 are independent of each other, thus ensuring the effective storage of ingredients in each area.

[0105] In some embodiments of this application, the partition plate 43 is arranged along the height direction of the vacuum drawer 4, and the partition plate 43 divides the internal space of the vacuum drawer 4 into a storage area 451 and a pickling area 452.

[0106] In other words, the partition 43 is set vertically, and the storage area 451 and the marinating area 452 are arranged along the front-back direction or left-right direction of the vacuum drawer 4. At this time, the magnetic component 5 is located above and / or below the storage area 451 and the marinating area 452, so that the magnetic field can pass through the storage area 451 and the marinating area 452 better, thereby improving the food preservation effect.

[0107] In some embodiments of this application, the partition plate 43 divides the internal space of the vacuum drawer 4 into a storage area 451 and a marinating area 452, which are arranged along the height of the vacuum drawer 4.

[0108] In other words, the partition 43 is set horizontally, and the storage area 451 and the marinating area 452 are arranged along the vertical direction of the vacuum drawer 4. At this time, the magnetic component 5 is located in front of and / or behind the storage area 451 and the marinating area 452, so that the magnetic field can pass through the storage area 451 and the marinating area 452 better, thereby improving the food preservation effect.

[0109] In some embodiments of this application, a plurality of storage spaces are formed inside the vacuum drawer 4, at least one of which is a pickling area 452. A plurality of magnetic elements 5 are provided, and the plurality of storage spaces and the plurality of magnetic elements 5 are provided in a one-to-one correspondence. The magnetic field strength generated by any magnetic element 5 is different.

[0110] In other words, the internal space of the vacuum drawer 4 is divided into multiple storage spaces by the partition 43. Some storage spaces serve as storage areas 451, while others serve as marinating areas 452. Each storage space has a corresponding magnetic component 5 to ensure that the magnetic field strength within each storage space is different. For example, the multiple storage spaces are respectively divided into weak magnetic space, medium magnetic space, and strong magnetic space to meet the storage magnetic field requirements of different types of food.

[0111] In some embodiments of this application, the first magnetic field shielding device 44 is detachably connected to the vacuum drawer 4. By assembling and disassembling the first magnetic field shielding device 44, its position can be changed, allowing the magnetic field generated by the magnetic component 5 to act on the marinating area 452, or isolating the marinating area 452 from the magnetic field.

[0112] For example, the first magnetic field shielding device 44 can be adopted as follows: Figure 6 The shielding structure shown is illustrated. For example, the first magnetic field shielding device 44 can be a flat plate structure, detachably mounted at the top opening of the marinating zone 452. The first magnetic field shielding device 44 is detachably mounted at the top opening of the marinating zone 452.

[0113] When the ingredients are marinated in the marinating zone 452, the first magnetic field shielding device 44 is installed on the vacuum drawer 4. The first magnetic field shielding device 44 covers the position of the marinating zone 452 so that the magnetic field generated by the magnetic component 5 cannot act on the marinating zone 452, thus isolating the marinating zone 452 from the magnetic field.

[0114] After the ingredients in the marinating zone 452 have been marinated, the first magnetic field shielding device 44 is removed from the vacuum drawer 4. At this time, the magnetic field shielding of the marinating zone 452 by the first magnetic field shielding device 44 is released, and the magnetic field acts on the marinating zone 452.

[0115] In some embodiments of this application, the first magnetic field shielding device 44 is foldably mounted on the vacuum drawer 4. By folding or unfolding the first magnetic field shielding device 44, a positional change is achieved, so that the magnetic field generated by the magnetic component 5 can act on the marinating area 452, or the marinating area 452 can be isolated from the magnetic field.

[0116] For example, the first magnetic field shielding device 44 has a folding structure, and the folding shielding device folds or unfolds based on the wall of the pickling zone 452.

[0117] When the ingredients are marinated in the marinating zone 452, the first magnetic field shielding device 44 is deployed. The first magnetic field shielding device 44 covers the marinating zone 452 so that the magnetic field generated by the magnetic component 5 cannot act on the marinating zone 452, thus isolating the marinating zone 452 from the magnetic field.

[0118] After the ingredients in the marinating zone 452 are marinated, the first magnetic field shielding device 44 is folded, and the magnetic field shielding of the marinating zone 452 by the first magnetic field shielding device 44 is released, and the magnetic field acts on the marinating zone 452.

[0119] In some embodiments of this application, the controller is configured to determine the marinating time of the food based on the weight of the food in the marinating zone 452.

[0120] Controlling the marinating time according to the weight of the ingredients can prevent the ingredients from being marinated for too little or too long. The appropriate marinating time helps to improve the marinating effect.

[0121] In some embodiments of this application, the controller is also configured to start the marinating timer when the vacuum level in the marinating zone 452 reaches a preset value.

[0122] The marinating effect is also related to the vacuum level. A vacuum creates a negative pressure environment, increasing the internal porosity of the food and facilitating the penetration of the marinating liquid. Maintaining this negative pressure for a period of time allows the marinating liquid to contact the food more evenly and to the greatest extent possible. When the food is first placed in the marinating zone, the system registers its weight. However, the marinating zone 452 is not yet a vacuum environment. The pressure within the marinating zone 452 needs time to change from atmospheric pressure to a vacuum. Therefore, the marinating timer is set to start when the vacuum level in the marinating zone 452 reaches a preset value. This ensures that the marinating process within the timer occurs entirely within a vacuum environment, guaranteeing the best marinating results.

[0123] If the set vacuum level has not been reached in the marinating zone 452 when the marinating timer starts, the marinating liquid cannot penetrate the food properly, and the food will not be marinated properly before the marinating timer ends, thus reducing the marinating effect.

[0124] The above are merely preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
