Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] Refrigerators can be used to store items and prolong the shelf life of items. They are indispensable home appliances for contemporary families. At present, refrigerators are not only the main appliance for storing food, but also have certain food processing functions, such as pickling food.

[0003] The existing technology usually uses a vacuum environment to accelerate the pickling of food, and uses a magnetic field to preserve the food. This is because a vacuum will produce a negative pressure environment, the gaps inside the food will increase, which is conducive to the penetration of the pickling liquid. Maintaining the negative pressure for a period of time can allow the pickling liquid to contact the food to the greatest extent and more evenly. In addition, because the water, enzymes, proteins, etc. in the food are anti-magnetic substances, their movement is chaotic. Therefore, after adding a magnetic field, the movement of water and other substances in the food is more orderly, which can slow down the metabolism and physiological and biochemical reaction rates of the food and extend the shelf life.

[0004] However, the refrigerator of the prior art adds a magnetic field device to the entire vacuum drawer to improve the preservation of fresh fruits, but the effect of the magnetic field in suppressing the activity of anti-magnetic substances such as moisture conflicts with the effect of vacuum accelerated pickling, which will affect the effects of accelerated pickling and storage preservation. Moreover, the pickling method and storage method of the food ingredients in the prior art refrigerator also remain under the premise that accelerated pickling and storage preservation interfere with each other.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In view of the problems pointed out in the background technology, the present invention provides a refrigerator which controls the vacuum degree and temperature according to the types of food, thereby improving the preservation and storage effect of food.

[0007] The purpose of this application is achieved through the following technical solutions: A refrigerator is provided, comprising a box body, an inner tank is arranged in the box body, the inner tank forms a receiving cavity with a front opening, a door body is rotatably arranged in the box body, and the door body is used to open and close the receiving cavity; a vacuum drawer is arranged in the receiving cavity, a vacuum environment can be formed inside the vacuum drawer, and a storage area and a pickling area are formed in the vacuum drawer; the magnetic part is configured to make the storage area and the pickling area have a magnetic field; when the food in the pickling area is pickled, there is no magnetic field in the pickling area; after the food in the pickling area is pickled, there is a magnetic field in the pickling area. The controller is configured to control the vacuum degree and temperature in the pickling area according to the type of food in the pickling area. When the types of food in the storage area and the pickling area are different, the temperature in the vacuum drawer is adjusted according to the temperature required by the food in the storage area, and the vacuum degree in the vacuum drawer is adjusted according to the vacuum degree required by the food in the pickling area.

[0008] Beneficial effects: The pickling area is built into the vacuum drawer, and the vacuum environment is used to accelerate the pickling of ingredients. After pickling, the ingredients are stored in the pickling area, and the vacuum environment is used to extend the preservation time.

[0009] The magnetic field in the pickling area changes according to the pickling stage. When the food in the pickling area is pickled, the magnetic field generated by the magnetic part cannot act on the pickling area, and there is no magnetic field in the pickling area, avoiding the interference of the magnetic field on the pickling.

[0010] After pickling, the magnetic field generated by the magnetic part acts on the pickling area, and there is a magnetic field in the pickling area. The magnetic field improves the orderliness of the movement of water and other substances in the food, slows down the metabolism and physiological and biochemical reaction rate of the food, and prolongs the preservation time.

[0011] Since different ingredients have different optimal vacuum degrees and optimal temperatures, the vacuum degree and temperature in the marinating area can be controlled to increase the storage time and reduce the marinating time.

[0012] After reading the specific embodiments of the present invention in conjunction with the accompanying drawings, other features and advantages of the present invention will become more clear. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0019] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0020] As a common appliance in daily life, refrigerators are now widely used. Users can store food in refrigerators to prevent food from spoiling.

[0021] like Figure 1 , 2 As shown, the refrigerator in this embodiment includes a box body 1 and an inner container 2.

[0022] The box body 1 is used to form the overall appearance of the refrigerator. The box body 1 is roughly in the shape of a rectangular parallelepiped frame. The top of the box body 1 and the bottom of the box body 1 are opposite ends. From the top of the box body 1 to the bottom of the box body 1 is the height direction of the box body 1. The left side of the box body 1 and the right side of the box body 1 are opposite sides. From the left side of the box body 1 to the right side of the box body 1 is the width direction of the box body 1. The front side of the box body 1 and the back side of the box body 1 are opposite sides. From the front side of the box body 1 to the back side of the box body 1 is the thickness direction of the box body 1. The liner 2 is arranged in the box body 1.

[0023] A refrigerating chamber is arranged inside the inner tank 2, and the refrigerating chamber is used to place items. The refrigerating chamber has a chamber opening, and the chamber opening direction is arranged toward the front side of the box body 1. The refrigerating chamber can be a refrigerating temperature environment, a freezing temperature environment, or a normal temperature environment. A door body 3 is arranged at the chamber opening, and the door body 3 is arranged in a straight plate shape at the front side of the box body 1. The door body 3 can be connected to the box body 1 in an openable and closable manner to open or close the refrigerating chamber.

[0024] It can be understood that the refrigerator also includes a refrigeration system and an air supply system. The refrigeration system is installed in the box 1, and the refrigeration system is used to provide cold air to the refrigeration room; the refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device and a refrigerant. Each component is distributed at different positions of the box 1 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after the power cord of the refrigerator is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device. The throttling device is used to throttle and reduce the pressure, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0025] The air supply system is installed in the box 1 to provide power for the flow of cold air. The air supply system generally includes a fan and a guide cavity. In some embodiments, the air inlet end of the guide cavity is arranged close to the fan, and the air outlet end of the guide cavity is arranged away from the fan. In other embodiments, the air outlet end of the guide cavity is arranged close to the fan, and the air inlet end of the guide cavity is arranged away from the fan. The fan drives the air in the guide cavity, and the evaporator is correspondingly arranged in the guide cavity. The cold air cooled by the evaporator flows along the guide cavity through the driving part of the fan. The cold air passes through the installation space formed between the inner tank 2 and the box 1, and finally enters the cold storage room to perform cooling operation on the cold storage room.

[0026] Based on the above structure, Figure 1-Figure 8 As shown, the present application proposes a refrigerator, comprising: a box body 1, an inner tank 2, a door body 3, a vacuum drawer 4 and a magnetic part 5.

[0027] The inner liner 2 is installed in the box body 1 , and the inner liner 2 is provided with a receiving cavity 21 with a front opening. The door body 3 is rotatably installed on the box body 1 and is used to open and close the receiving cavity 21 .

[0028] The vacuum drawer 4 is installed in the accommodating cavity 21 , and a vacuum environment can be formed inside the vacuum drawer 4 .

[0029] The magnetic member 5 is installed on the vacuum drawer 4 and is used to form a magnetic field inside the vacuum drawer 4 .

[0030] The vacuum drawer 4 includes: a fixing portion 41 , a drawer portion 42 , a partition plate 43 and a first magnetic field shielding device 44 .

[0031] The fixing portion 41 is installed in the accommodating cavity 21 and a front end of the fixing portion 41 is open.

[0032] The drawer portion 42 is inserted into the front end opening of the fixing portion 41 and can be slidably installed in the fixing portion 41 . The drawer portion 42 has a storage cavity 45 with a top opening.

[0033] The partition plate 43 is installed in the storage cavity 45 to separate the storage cavity 45 into a storage area 451 and a pickling area 452. The first magnetic field shielding device 44 is installed in the pickling area 452 to block the magnetic field from entering the pickling area 452, so that there is no magnetic field inside the pickling area 452.

[0034] Based on the above technical scheme, the vacuum drawer 4 of the present application can form a vacuum environment, and the magnetic part 5 arranged on the vacuum drawer 4 can form a magnetic field in the vacuum drawer 4, and the space of the vacuum drawer 4 is divided into a storage area 451 and a pickling area 452 by a partition plate 43, and a first magnetic field shielding device 44 is arranged in the pickling area 452, so that the storage area 451 forms a vacuum + magnetic field environment, and the pickling area 452 forms a vacuum environment, thereby enhancing the preservation effect of the storage area 451 and avoiding the interference of the magnetic field on the vacuum pickling.

[0035] It should be noted that there are many ways to set the partition board 43: The vacuum drawer 4 can be divided into two areas in the vertical direction, left and right or front and back. One is the pickling area 452, and the other is the storage area 451. The pickling area 452 has a vacuum and no magnetic field, and the storage area 451 has a vacuum and a magnetic field. The partition is installed in a plug-in manner in the vertical direction in a groove form. The vertical partition is installed in the 1\4-3\4 range on the left and right or front and back of the drawer, dividing the drawer volume into 1:3-3:1. Due to the different installation positions, the effective distance between the magnetic field device and the vacuum drawer 4 increases, and the magnetic field strength emitted by the magnetic field device needs to be adjusted. For every increase of 5cm, the magnetic field strength needs to be increased by 20%-50%.

[0036] It can be horizontal, dividing the drawer into two layers, with physical isolation between the upper and lower sides, and the partition is movable, including free access from top to bottom, and push-pull folding of the drawer to facilitate the storage of food in the lower area. Brackets are set on the side walls of the drawer, and the height of the bracket is between 1 / 5-4 / 5 of the height of the drawer. The bracket divides the volume of the upper and lower layers into 1:4-4:1.

[0037] In addition, when the partition board 43 is divided left and right, the left side of the drawer is the pickling area 452, and the right side is the storage area 451; when the partition board 43 is divided front and back, the front of the drawer is the pickling area 452, and the back is the storage area 451; when the partition board 43 is divided up and down, the lower part of the drawer is the pickling area 452, and the upper part is the storage area 451.

[0038] In some embodiments of the present application, a controller is further included, wherein the controller is configured to: obtain the marinating time of the food according to the weight of the food; and control the food to be marinated when the vacuum degree of the vacuum drawer 4 reaches a preset value. The controller in the refrigerator can automatically obtain the marinating time of the food according to the weight of the food, and control the food to be marinated when the vacuum degree of the drawer reaches a preset value, which is convenient to use.

[0039] Specifically, the controller is further configured to: control the vacuum degree and temperature of pickling and / or storing the food according to the type of food; obtain the moisture content of the pickled food, and adjust the magnetic field strength of the vacuum drawer 4 according to the moisture content. Since different food has different suitable environments, adjusting the vacuum degree, temperature and magnetic field strength according to the type of food can effectively improve the storage effect, increase the storage time, and reduce the time required for pickling.

[0040] In some embodiments of the present application, Figure 7 As shown, a weight identification device 6 for detecting the weight of food is provided in the vacuum drawer 4, the weight identification device 6 is electrically connected to the controller, and the weight identification device 6 is provided on the bottom surface of the vacuum drawer 4. The weight identification device 6 can automatically measure the weight of food after putting food in, thereby improving the automation of refrigerator pickling.

[0041] In some embodiments of the present application, Figure 7 As shown, a camera assembly 7 is provided in the vacuum drawer 4 for obtaining the type of food and / or the moisture content of the food in the vacuum drawer 4. The camera assembly 7 is electrically connected to the controller and is installed on the top of the vacuum drawer 4, specifically the top of the fixed portion 41.

[0042] The camera assembly 7 can identify the type of food and provide feedback to the controller to adjust the temperature, working level and vacuum degree of the drawer.

[0043] In addition, the moisture sensing component in the camera component 7 identifies the moisture content in the food, feeds back to the controller, and adjusts the magnetic field strength in the area.

[0044] The camera assembly 7 can rotate at a certain angle, which can be 0°-90° in the vertical direction and 360° in the horizontal direction, so as to be able to scan the food in the vacuum drawer 4 in an all-round manner; the food moisture content recognition device can be the camera assembly 7, such as a near-infrared spectrum, which recognizes the moisture content in the food through spectral imaging; or it can be a moisture sensor, which recognizes the moisture content in the food through capacitance monitoring. The moisture content of common foods is shown in Table 1.

[0045] Table 1

[0046] In some embodiments of the present application, Fig. 9 As shown, the vacuum drawer 4 further includes a second magnetic field shielding device 46, which is arranged around the outer periphery of the fixing portion 41, and the magnetic member 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 member 5 is 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 cannot be disassembled to ensure the stability of its structure.

[0047] In some embodiments of the present application, Figure 3 , Figure 4 As shown, the fixing part 41 includes an upper cover plate 411, a vacuum barrel 412 and a lower cover plate 413 which are sequentially installed on the accommodating cavity 21 from top to bottom, 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 barrel 412. The front end of the vacuum barrel 412 is open. The drawer 42 is inserted into the front end opening of the vacuum barrel 412 and can be installed on the vacuum barrel 412 in a sliding manner. A controller is integrated on the control panel 414. The control panel 414 is preferably installed on the front end of the upper cover plate 411 in the form of a bayonet. The gear position, magnetic device, camera, moisture sensor, refrigeration, etc. of the vacuum drawer 4 are all uniformly controlled by the controller, and the working gear positions such as fruits and vegetables, fresh food, and smart food can be set on the control panel 414 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 placing the vacuum barrel 412 therein, and the control panel 414 can control the environment inside the vacuum barrel 412 so that the environment of the vacuum barrel 412 reaches a better state. The front end of the vacuum barrel 412 is open, so that the pull-out part 42 can be installed in the vacuum barrel 412 by sliding forward and backward to realize the basic function of the drawer.

[0048] In addition, reference Figure 3 , Figure 4, Figure 7 , based on the existing vacuum refrigerator, a magnetic field generating device, i.e., a magnetic part 5, is added to the upper and lower parts, left and right parts, or front and back parts of the vacuum barrel 412. The magnetic part 5 can be any one of a magnetic sheet, an electromagnetic coil, and a magnet, and there is at least one magnetic part 5. If it is a single magnetic part 5, it can be on one side of the vacuum drawer 4, taking the magnetic part 5 being located at the upper or lower part of the vacuum drawer 4 as an example. When the magnetic part 5 is at the upper part of the vacuum drawer 4, it can be on the inner wall or outer wall of the top of the vacuum barrel 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 wall or outer wall of the air duct assembly cover plate 415, it can be on the upper or lower layer of the air duct foam 416; it can also be on the inner wall or outer wall of the upper cover plate 411; it can also be on the bottom of the upper drawer of the vacuum drawer 4, or on the inner wall or outer wall of the bottom partition. When the magnetic part 5 is at the bottom of the vacuum drawer 4, it can be on the inner wall or outer wall at the bottom of the vacuum barrel 412; it can also be on the inner wall or outer wall at the bottom of the vacuum drawer 4; it can also be on the inner wall or outer wall at the bottom of the inner liner 2 of the box body 1 corresponding to the vacuum drawer 4; it can also be installed on the inner wall or outer wall of the top cover of the lower drawer of the vacuum drawer 4; it can also be installed on the inner wall, outer wall or inner interlayer of the partition inside the vacuum drawer 4. Based on the different types of magnetic parts 5, the installation method can be pasting, screws and buckles; when the magnetic part 5 is on the inner liner 2 of the box body 1, the installation method also depends on foaming. At this time, the surface tension of the side of the magnetic part 5 in contact with the foam material is required to be ≥38N / m to prevent bubbles from being generated during the foaming process, causing the inner liner 2 to bulge.

[0049] If there are two magnetic members 5, any one of the magnetic members 5 can be installed in the same position and manner as the above-mentioned single magnetic member 5, but the two magnetic members 5 should be placed in parallel, with the N pole and the S pole facing each other. The magnetic member 5 should be at a 90° angle to the accessible partition plate 43 in the vacuum drawer 4, so that the pickling area 452 can shield the external magnetic field by means of a shielding device, while the magnetic field of the storage area 451 is not disturbed. The magnetic field shielding device can be a magnetic shielding agent coating, a magnetic shielding cover, etc., and the magnetic shielding device can be inside the pickling area 452 or outside the pickling area 452.

[0050] In some embodiments of the present application, Figure 5 , Figure 6As shown, the vacuum drawer 4 also includes a slide rail 47, and the slide rail 47 is installed on the drawer 42, and the first magnetic field shielding device 44 is slidably installed on the slide rail 47. The pickling area 452 needs to shield the magnetic field, so the first magnetic field shielding device 44 is set inside the pickling area 452 to block the magnetic field from entering the pickling area 452. However, since the fixing part 41 and the drawer 42 are separated, it is difficult to cover the entire pickling area 452 by setting the first magnetic field shielding device in the pickling area 452. At the same time, it is also necessary to consider how to set the first magnetic shielding device to cover the entire pickling area 452 and have 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 rely on a magnetic attraction limit device to fix its position on the slide rail 47. 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 arranged on opposite sides of the top plate, and the two side plates are located on different sides from the partition plate 43. The first magnetic field shielding device 44 also includes a vertically arranged partition plate 43 with magnetic shielding material, and the magnetic shielding material is only arranged on the side close to the pickling area 452, which does not 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 arranged at the bottom of the pickling area 452, and the magnetic shielding material is arranged in the superconducting plate. Therefore, the above-mentioned first magnetic field shielding device 44 includes 6 magnetic shielding surfaces, and the magnetic field shielding cover, the partition plate 43, the side plates and the bottom plate of the pickling area 452 can be detached, which is convenient for users to use and also conducive to the functional use of the vacuum drawer 4.

[0051] That is, when pickling is not required, the first magnetic field shielding device 44 is taken out, and the entire vacuum drawer is configured as the storage area 451. When pickling is required, the first magnetic field shielding device 44 is installed to accelerate pickling.

[0052] The first magnetic field shielding device 44 may also be installed as a whole at the front or rear of the drawer. In this case, any area where the first magnetic field shielding device 44 is installed may be used as the pickling area 452 .

[0053] In some embodiments of the present application, Fig.10 As shown, in order to improve the preservation effect, a sterilization and deodorization device 8 can be set in the storage area 451, such as a passive sterilization and deodorization device 8 such as a catalyst block, activated carbon, or an active sterilization and deodorization device 8 such as an ion module, a light sterilization module, etc.

[0054] The present application also provides a food pickling and storage control method based on the above refrigerator, comprising the following steps: obtaining the food pickling time according to the weight of the food; and controlling the food to be pickled when the vacuum degree of the vacuum drawer 4 reaches a preset value. When the vacuum drawer 4 of the refrigerator is used for pickling, the food pickling time can be significantly reduced, and the food pickling time can be automatically obtained according to the weight of the food, and pickling starts when the vacuum degree reaches a preset value, which saves time and is easy to operate.

[0055] In some embodiments of the present application, before the step of controlling the marinating time of the ingredients according to the weight of the ingredients, it also includes: establishing a correspondence between the preset ingredient weight and the marinating time; obtaining the marinating scene of the ingredients; and obtaining the corresponding ingredient weight according to different marinating scenes.

[0056] In order to further realize the automated pickling of the refrigerator, based on the previous research data, the weight of the ingredients can be matched with the pickling time, and the data can be input into the refrigerator. When the refrigerator obtains the weight of the ingredients, it can automatically prompt the pickling time. Among them, the refrigerator can also identify the weight of the ingredients according to different pickling scenarios, and the pickling time is more accurate.

[0057] Specifically, the pickling scenarios include no-container scenarios, standard container scenarios, and other container scenarios.

[0058] When the pickling scene is without a container, the food weight m1 is obtained and the pickling time is controlled to be T1, wherein the food weight m1 is detected by the weight identification device 6 in the vacuum drawer 4.

[0059] When the pickling scene is a standard container, the food weight m2 is calculated, and the pickling time is controlled to be T2. m2 satisfies: m2=m2'-m0, where m2' is the total weight of the standard container and the food weight, and m0 is the standard container weight of the refrigerator.

[0060] When the pickling scene is other containers, the food weight m3 is obtained and the pickling time is controlled to be T3, wherein the food weight m3 is manually input by the user.

[0061] Depending on the pickling container, the identification of food weight can be divided into three different situations, namely, no container scenario, standard container scenario and other container scenarios, and the food weight can be obtained according to different scenarios, thereby obtaining a more accurate pickling time.

[0062] For the case where only ingredients are pickled: based on the weight m1 of the pickled ingredients and the data from previous studies, the pickling time T1 is automatically prompted, which is defined as the first type of pickled ingredients, and the pickling container is defined as "no container"; For pickling using the standard vacuum jar (box) and vacuum bag that comes with the refrigerator: the pickling time is determined based on the weight difference. First, let the user choose whether to use a vacuum jar or a vacuum bag, then weigh the weight of the container and the food m2', and then automatically deduct the weight of the container itself m0 to get the net weight of the food m2. According to the data of the previous study, the pickling time T2 is automatically prompted. The weight of the container itself is an internal product and can be entered into the database in advance. The weight of the pickling container itself is m0, which is defined as the second type of pickled food, and the pickling container is defined as a "standard container"; For pickling in other pickling containers: set up an input interface on the screen or APP, and let the user select the net weight of the pickled ingredients, such as 0-1000g, with each 50g as a level, corresponding to different pickling times. After pickling is completed, the screen or APP reminds the user. The net weight of such ingredients is m3, which is defined as the third type of pickled ingredients. According to the data of the previous study, the pickling time T2 is automatically prompted. The pickling container is defined as "other container".

[0063] In some embodiments of the present application, the weight of the food is in the range of 200g-500g, and the corresponding pickling time is in the range of 10min-25min, and the pickling time increases by 1min-3min for every 50g increase in the weight of the food. By adopting the above-mentioned correspondence between the weight of the food and the pickling time, the pickling of the food can be achieved more quickly and comprehensively, and the reliable pickling of food of different weights can be automatically completed.

[0064] In some embodiments of the present application, the following steps are also included: receiving an instruction to add new ingredients, determining the marinating status of the previous ingredients, and controlling the marinating time of the previous ingredients and the new ingredients according to the marinating status of the previous ingredients.

[0065] When the marinating state of the previous food is not yet marinated, the marinating time of the previous food is controlled to be paused while adding the new food. After adding the new food, the marinating time of the new food is obtained. When the vacuum degree of the vacuum drawer 4 reaches a preset value, the marinating time of the previous food is controlled to resume timing, and the marinating time of the new food is controlled to start timing.

[0066] When the marinating state of the previous food is that the marinating is completed, the previous food is taken out while adding the new food. After adding the new food, the marinating time of the new food is obtained. When the vacuum degree of the vacuum drawer 4 reaches the preset value, the marinating time of the new food is controlled to start timing.

[0067] During the pickling process, in addition to the situation where the food is placed in the empty pickling area 452, there is also the following situation: when the first food is being pickled, the second pickled food or the third pickled food is added.

[0068] At this time, based on the above basic pickling method, set a segmented timer on the screen or APP (displaying the pickling time and the remaining pickling time information respectively, so that users can understand the specific information of each ingredient verification, and remind them after the pickling is completed).

[0069] Specifically: (1) For a first ingredient to be marinated, if the door is opened and a second ingredient is put in during the marinating process, the marinating time of the first ingredient is suspended 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 degree reaches a preset value, and the marinating time of the first ingredient continues until the marinating is completed.

[0070] (2) For the second ingredient, after the second ingredient is placed in the machine and the door is closed, the vacuum is started and the timing starts when the vacuum degree reaches the preset value. If the door is opened during the process, the timing will be carried out according to (1). If there is no interruption during the process, the timing will be carried out according to the basic logic until the marinating is completed.

[0071] (3) If there are 3rd, 4th, 5th or more ingredients, follow this method.

[0072] Furthermore, in combination with the situations of different containers, a common implementation method is described: (1) When the first ingredient is placed in a no-container scenario, the pickling container is selected as "none", and the weight identification device 6 directly weighs the weight m1, outputs the pickling time T1 of the first ingredient, and starts vacuuming after closing the door. When the vacuum degree reaches the preset value, the pickling time automatically starts; (2) When the first ingredient is pickled, the door is opened to place the second ingredient in the standard container scenario, 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', and 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, and the timing starts when the door and drawer are closed and the vacuum degree reaches the preset value. At the same time, the timing of the first type of pickled ingredient continues until the pickling is completed. (3) During the pickling process of the first and second categories of ingredients, if ingredients using other container scenarios are added, the user selects the pickling container as "other" and enters the weight m3 of the third category of pickled ingredients, then m3 is the net weight of this category of ingredients. The pickling timer starts when the vacuum degree reaches the preset value after the door is closed, and a reminder is given after completion. (4) During the pickling process, if the first category of pickled ingredients is finished, after the user opens the door to take out the ingredients, if no new pickled ingredients are put in, the pickling timer for other ingredients will continue when the vacuum degree reaches the preset value after the door is closed. (5) If the user opens the door to take out the pickled ingredients, if new pickled ingredients are put in, the pickling program for the new pickled ingredients must be run according to the above-mentioned process for adding new ingredients, and the existing pickled ingredients will continue to be pickled after the vacuum degree reaches the preset value. (The weight sensor only works after the ingredients are put in. The net weight of the ingredients taken out after pickling does not need to be identified because no new pickling action is required.) In some embodiments of the present application, the following steps are further included: according to the type of food, the vacuum degree and temperature of the food pickling and / or storage are controlled. Since different food has different optimum vacuum degree and optimum temperature, the vacuum degree and temperature in the vacuum drawer 4 can be controlled to increase the storage time and reduce the pickling time.

[0073] Specifically, the types of food are fruits and vegetables, fresh meat or other types; when the food is fruits and vegetables, the vacuum degree of the vacuum drawer 4 is controlled to be 750hpa-850hpa, and the temperature of the vacuum drawer 4 is controlled to be 2℃-8℃; when the food is fresh meat, the vacuum degree of the vacuum drawer 4 is controlled to be 650hpa-750hpa, and the temperature of the vacuum drawer 4 is controlled to be -5℃-0℃; when the food is other food, the vacuum degree of the vacuum drawer 4 is controlled to be 700hpa-800hpa, and the temperature of the vacuum drawer 4 is controlled to be 0℃-2℃.

[0074] Since different ingredients have different requirements for vacuum degrees and storage temperatures, different vacuum degrees are set according to the type of ingredients. Through the above method, the pickling speed of the same ingredients can be shortened by 2-3 times compared to ordinary pickling, and the storage time can also be greatly increased.

[0075] More specifically, when the types of food in the storage area 451 and the pickling area 452 are different, the temperature of the vacuum drawer 4 is controlled to be a temperature suitable for storing the food in the storage area 451, and when the pickling area 452 is working, the vacuum degree of the vacuum drawer 4 is controlled to be a vacuum degree suitable for the working of the pickling area 452; when the pickling area 452 is not working, the vacuum degree of the vacuum drawer 4 is controlled to be a vacuum degree suitable for storing the food in the storage area 451.

[0076] Temperature has a greater impact on storage, while vacuum has a greater impact on pickling. Therefore, when the types of food in the storage area 451 and the pickling area 452 are different, priority is given to ensuring the temperature of the food in the storage area 451 and the vacuum in the pickling area 452, so that both the storage and pickling of the food can be taken into account.

[0077] More specifically, when the types of food in the storage area 451 are different, the temperature of the vacuum drawer 4 is controlled to be a food storage temperature with a relatively high optimum storage temperature. The temperature selection of the storage area 451 needs to be determined based on the type of food in the storage area 451. Generally speaking, food with a higher storage temperature, such as fruits and vegetables, has a higher temperature requirement than fresh food. Therefore, when the types of food in the storage area 451 are different, the storage temperature is preferably determined based on the food with a relatively high optimum storage temperature. For example, if the storage area 451 stores fruits and vegetables, and the pickling area 452 is for beef, the temperature of the vacuum drawer 4 is adjusted to 2-8°C to meet the conditions required for fruit and vegetable storage. When the pickling function is turned on, the vacuum degree in the vacuum drawer 4 is 650-750hpa, and the vacuum degree is adjusted to 750-850hpa after the pickling process is completed.

[0078] Specifically, the method further 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 the important factor of magnetic field preservation is the moisture content, different types of food have different moisture contents, and the optimal magnetic field strength required is different, so the magnetic field strength needs to be adjusted according to the type of food to increase the storage time.

[0079] More specifically, when the moisture content of the food is 0%-30%, the magnetic field strength in the vacuum drawer 4 is controlled to be 8mT-10mT; when the moisture content of the food is 30%-50%, the magnetic field strength in the vacuum drawer 4 is controlled to be 6mT-8mT; when the moisture content of the food is 50%-70%, the magnetic field strength in the vacuum drawer 4 is controlled to be 4mT-6 mT; when the moisture content of the food is 70%-90%, the magnetic field strength in the vacuum drawer 4 is controlled to be 2mT-4mT; when the moisture content of the food is >90%, the magnetic field strength in the vacuum drawer 4 is controlled to be 0mT-2mT. By controlling the magnetic field in the vacuum drawer 4 in the above manner, the storage time of the food can be further increased.

[0080] In summary, in the refrigerator and the food pickling and storage control method of the present application, the vacuum drawer 4 can form a vacuum environment, and the magnetic part 5 arranged on the vacuum drawer 4 can form a magnetic field in the vacuum drawer 4, and the space of the vacuum drawer 4 is divided into a storage area 451 and a pickling area 452 by a partition plate 43, and a first magnetic field shielding device 44 is arranged in the pickling area 452, so that the storage area 451 forms a vacuum + magnetic field environment, and the pickling area 452 forms a vacuum environment, thereby enhancing the preservation effect of the storage area 451 and avoiding the interference of the magnetic field on the vacuum pickling. When the vacuum drawer 4 of the refrigerator is used for pickling, the pickling time of the food can be significantly reduced, and the pickling time of the food can be automatically calculated according to the weight of the food. Pickling starts when the vacuum degree reaches a preset value, which saves time and is easy to operate.

[0081] In some embodiments of the present application, a pickling area 452 is formed in the vacuum drawer 4, and the pickling area 452 is configured to perform vacuum pickling and storage on the food. In other words, the pickling area 452 is built into the vacuum drawer 4, and the vacuum environment is used to accelerate the pickling of the food. After the pickling is completed, the food is stored in the pickling area 452, and the vacuum environment is used to extend the preservation time.

[0082] The magnetic member 5 is configured to provide a magnetic field in the pickling area 452. When the food in the pickling area 452 is pickled, there is no magnetic field in the pickling area 452. After the food in the pickling area 452 is pickled, there is a magnetic field in the pickling area 452.

[0083] In other words, the magnetic field in the pickling area 452 changes according to the pickling stage. Specifically, when the food in the pickling area 452 is pickled, the magnetic field generated by the magnetic element 5 cannot act on the pickling area 452, and there is no magnetic field in the pickling area 452, avoiding interference of the magnetic field on pickling.

[0084] After pickling is completed, the magnetic field generated by the magnetic element 5 acts on the pickling area 452, and there is a magnetic field in the pickling area 452. The magnetic field improves the orderliness of the movement of water and other substances in the food, slows down the metabolism and physiological and biochemical reaction rate of the food, and prolongs the preservation time.

[0085] In some embodiments of the present application, the controller is configured to obtain the marinating time of the food according to the weight of the food in the marinating area 452 .

[0086] Controlling the marinating time according to the weight of the ingredients can avoid insufficient or excessive marinating time. Appropriate marinating time helps improve the marinating effect.

[0087] In some embodiments of the present application, the controller is further configured to start the pickling timer when the vacuum degree in the pickling area 452 reaches a preset value.

[0088] The pickling effect is also related to the vacuum degree. Vacuum will produce a negative pressure environment, and the internal gaps of the food will increase, which is conducive to the penetration of the pickling liquid. Maintaining the negative pressure for a period of time can make the pickling liquid contact the food to the greatest extent and more evenly. When the food is just put into the pickling area, the system obtains the weight of the food, but at this time the pickling area 452 is not a vacuum environment. The pressure in the pickling area 452 changes from normal pressure to a vacuum environment, which requires a certain amount of vacuuming time. Therefore, when the vacuum degree in the pickling area 452 reaches a preset value, the pickling timer starts. In this way, the pickling process within the pickling timer occurs in a vacuum environment, ensuring the pickling effect of the food.

[0089] If the set vacuum degree has not been reached in the pickling area 452 when the pickling timer starts, the pickling liquid cannot penetrate into the food well, the food is not pickled well, and the pickling timer ends, thereby reducing the pickling effect.

[0090] In some embodiments of the present application, the magnetic member 5 is an electromagnetic generating device. For example, the electromagnetic generating device is an electromagnetic coil.

[0091] When the food in the pickling area 452 is pickled, the electromagnetic generating device is powered off, the electromagnetic generating device does not generate a magnetic field, and there is no magnetic field in the pickling area 452, thereby avoiding interference of the magnetic field on the pickling.

[0092] After the food in the pickling area 452 is pickled, the electromagnetic generating device is powered on, and the electromagnetic generating device generates a magnetic field, which acts on the pickling area 452, and a magnetic field is formed in the pickling area 452.

[0093] By turning the electromagnetic generator on and off, the magnetic field in the pickling area 452 can be changed, which is convenient for control.

[0094] In some embodiments of the present application, the magnetic field strength generated by the electromagnetic generating device is adjustable. Since the important factor of magnetic field preservation is moisture content, different types of food have different moisture contents and require different optimal magnetic field strengths, so the magnetic field strength needs to be adjusted according to the moisture content of the food to improve the preservation effect.

[0095] By controlling the current of the electromagnetic generating device, the size of the magnetic field can be adjusted to meet the needs of preservation and storage of food with different water contents, making it easier to control.

[0096] In some embodiments of the present application, the refrigerator also includes a controller, which is connected to the electromagnetic generating device, and the controller is configured to adjust the magnetic field strength of the electromagnetic generating device according to the moisture content of the food in the marinating area 452 after marinating.

[0097] When the food in the pickling area 452 is pickled, the electromagnetic generator is powered off and does not generate a magnetic field, and there is no magnetic field in the pickling area 452. After the food in the pickling area 452 is pickled, the moisture content in the pickled food is identified by the moisture sensing component described above and fed back to the controller, which then adjusts the magnetic field strength of the electromagnetic generator to improve the preservation and storage effect of the pickled food.

[0098] In some embodiments of the present application, the magnetic member 5 is a static magnetic generating device. For example, the static magnetic generating device is a magnetic sheet, a magnet, etc.

[0099] Since the static magnetic generating device generates a magnetic field all the time, and the pickling area 452 needs to shield the magnetic field during the pickling process, the refrigerator further includes a first magnetic field shielding device 44. The first magnetic field shielding device 44 is configured to isolate the pickling area 452 from the magnetic field generated by the static magnetic generating device when the food in the pickling area 452 is pickled.

[0100] In other words, when the food in the pickling area 452 is pickled, the first magnetic field shielding device 44 is used to isolate the magnetic field of the pickling area 452, and the magnetic field generated by the magnetic component 5 cannot act on the pickling area 452. There is no magnetic field in the pickling area 452, avoiding the interference of the magnetic field on the pickling.

[0101] After pickling is completed, the first magnetic field shielding device 44 releases the magnetic field shielding of the pickling area 452, and the magnetic field generated by the magnetic element 5 acts on the pickling area 452, and there is a magnetic field in the pickling area 452. The magnetic field improves the orderliness of the movement of water and other substances in the food, slows down the metabolism and physiological and biochemical reaction rate of the food, and prolongs the preservation time.

[0102] In some embodiments of the present application, a storage area 451 is further formed in the vacuum drawer 4, and the storage area 451 is configured to store food in a vacuum-preserved manner. The magnetic member 5 is configured to provide a magnetic field in the storage area 451 and the pickling area 452.

[0103] In other words, the storage area 451 and the pickling area 452 are provided in the vacuum drawer 4 to meet the different storage requirements of food. Food in the storage area 451 and the pickling area 452 can use the magnetic field generated by the magnetic element 5 to extend the preservation time. When the food in the pickling area 452 is pickled, there is no magnetic field in the pickling area 452 to avoid interference of the magnetic field with the pickling process. At this time, there is still a magnetic field in the storage area 451, so the pickling area 452 and the storage area 451 are independent of each other, thereby ensuring the storage effect of the food in each area.

[0104] In some embodiments of the present application, the storage area 451 and the pickling area 452 are respectively configured with magnetic parts 5, so that the magnetic field changes in the storage area 451 and the pickling area 452 are independent of each other to meet the changing demand for magnetic field for food storage in each area.

[0105] For example, the magnetic member 5 corresponding to the storage area 451 is a static magnetic generating device, and the magnetic member 5 corresponding to the pickling area 452 is an electromagnetic generating device. For another example, the magnetic member 5 corresponding to the storage area 451 is a static magnetic generating device, and the magnetic member 5 corresponding to the pickling area 452 is a static magnetic generating device. For another example, the magnetic member 5 corresponding to the storage area 451 is an electromagnetic generating device, and the magnetic member 5 corresponding to the pickling area 452 is an electromagnetic generating device. For another example, the magnetic member 5 corresponding to the storage area 451 is an electromagnetic generating device, and the magnetic member 5 corresponding to the pickling area 452 is a static magnetic generating device.

[0106] In some embodiments of the present 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 marinating area 452 .

[0107] In other words, the partition plate 43 is vertically arranged, and the storage area 451 and the pickling area 452 are arranged along the front-to-back direction or the left-to-right direction of the vacuum drawer 4. At this time, the magnetic member 5 is located above and / or below the storage area 451 and the pickling area 452, so that the magnetic field can pass through the storage area 451 and the pickling area 452 well, so as to improve the food preservation effect.

[0108] In some embodiments of the present application, the partition plate 43 divides the inner space of the vacuum drawer 4 into a storage area 451 and a pickling area 452 , and the storage area 451 and the pickling area 452 are arranged along the height direction of the vacuum drawer 4 .

[0109] In other words, the partition plate 43 is arranged horizontally, and the storage area 451 and the pickling area 452 are arranged along the up-down direction of the vacuum drawer 4. At this time, the magnetic member 5 is located in front of and / or behind the storage area 451 and the pickling area 452, so that the magnetic field can pass through the storage area 451 and the pickling area 452 better to improve the food preservation effect.

[0110] In some embodiments of the present application, a plurality of storage spaces are formed in the vacuum drawer 4, at least one of the plurality of storage spaces is a pickling area 452, a plurality of magnetic members 5 are provided, the plurality of storage spaces and the plurality of magnetic members 5 are provided in one-to-one correspondence, and the magnetic field strength generated by any magnetic member 5 is different.

[0111] In other words, the internal space of the vacuum drawer 4 is divided into a plurality of storage spaces by the partition plate 43. Some storage spaces are used as storage areas 451, and some storage spaces are used as pickling areas 452. Each storage space has a corresponding magnetic member 5, so that the magnetic field strength in each storage space is different. For example, the plurality of storage spaces are respectively weak magnetic spaces, medium magnetic spaces, strong magnetic spaces, etc., to meet the storage magnetic field requirements of different types of food.

[0112] In some embodiments of the present application, the first magnetic field shielding device 44 is detachably connected to the vacuum drawer 4. The first magnetic field shielding device 44 is disassembled and assembled to achieve position change, so that the magnetic field generated by the magnetic member 5 can act on the pickling area 452, or the pickling area 452 is isolated from the magnetic field.

[0113] For example, the first magnetic field shielding device 44 may be formed as follows: Figure 6 As another example, the first magnetic field shielding device 44 may be a flat plate structure, and the flat plate shielding device is detachably disposed at the top opening of the pickling area 452. The first magnetic field shielding device 44 is detachably disposed at the top opening of the pickling area 452.

[0114] When the food in the pickling area 452 is pickled, the first magnetic field shielding device 44 is installed on the vacuum drawer 4. The first magnetic field shielding device 44 corresponds to the position covering the pickling area 452, so that the magnetic field generated by the magnetic member 5 cannot act on the pickling area 452, and the pickling area 452 is isolated from the magnetic field.

[0115] After the food in the pickling area 452 is pickled, the first magnetic field shielding device 44 is separated from the vacuum drawer 4 . At this time, the magnetic field shielding of the pickling area 452 by the first magnetic field shielding device 44 is released, and the magnetic field acts on the pickling area 452 .

[0116] In some embodiments of the present application, the first magnetic field shielding device 44 is foldably disposed on the vacuum drawer 4. By folding or unfolding the first magnetic field shielding device 44 to achieve position change, the magnetic field generated by the magnetic member 5 can act on the pickling area 452, or the pickling area 452 is isolated from the magnetic field.

[0117] For example, the first magnetic field shielding device 44 is a folding structure, and the folding shielding device performs a folding or unfolding movement based on the wall of the pickling area 452 .

[0118] When the food in the pickling area 452 is pickled, the first magnetic field shielding device 44 is deployed to cover the pickling area 452 so that the magnetic field generated by the magnetic element 5 cannot act on the pickling area 452, and the pickling area 452 is isolated from the magnetic field.

[0119] After the food in the pickling area 452 is pickled, the first magnetic field shielding device 44 is folded. At this time, the magnetic field shielding of the pickling area 452 by the first magnetic field shielding device 44 is released, and the magnetic field acts on the pickling area 452 .

[0120] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
