In order to improve the preservation effect, some existing refrigerators are equipped with electromagnetic preservation technology, which means that a magnetic field generating device is installed in the storage compartment. The magnetic field generating device applies a magnetic field to the storage compartment to inhibit the growth of microorganisms and enzyme activity, thereby extending the preservation time of food and improving the preservation effect.

[0003] However, magnetic field generators usually generate heat when operating, which in turn affects the temperature of the storage room and the preservation effect. Utility Model Content

[0004] This application provides a drawer assembly and a refrigerator to solve the problem that the magnetic field generator of existing refrigerators usually generates heat during operation, which affects the temperature of the storage compartment and thus affects the preservation effect.

[0033] With the development of science and technology, refrigerators have become one of the essential household appliances in people's daily lives. In order to improve the preservation effect, some existing refrigerators are equipped with electromagnetic preservation technology, which means that a magnetic field generating device is installed in the storage compartment. The magnetic field generating device applies a magnetic field to the storage compartment to inhibit the growth of microorganisms and enzyme activity, thereby extending the preservation time of food and improving the preservation effect.

[0034] However, magnetic field generators usually generate heat when operating, which in turn affects the temperature of the storage room and the preservation effect.

[0035] Therefore, this application provides a drawer assembly and a refrigerator to solve the problem that the magnetic field generating device of existing refrigerators usually generates heat during operation, which affects the temperature of the storage compartment and thus affects the preservation effect. The following will be described in conjunction with the accompanying drawings.

[0036] The drawer assembly provided in this application embodiment is applied to a refrigerator. The drawer assembly includes a drawer body 1 and a receiving box 2. Please refer to... Figure 1 The container box 2 is adjacent to the drawer body 1. The container box 2 is equipped with a magnetic field generating device 3, which is used to apply a magnetic field to the drawer body 1. The container box 2 is equipped with an openable and closable air door 21, which is used to open when the temperature of the container box 2 is higher than a first preset temperature and close when the temperature of the container box 2 is lower than a second preset temperature; wherein, the first preset temperature is higher than the second preset temperature.

[0037] The drawer assembly provided in this application embodiment has a receiving box 2 adjacent to the drawer body 1 and a magnetic field generating device 3 inside the receiving box 2. The magnetic field generating device 3 applies a magnetic field to the drawer body 1 to achieve electromagnetic preservation. At the same time, the receiving box 2 plays a certain role in separating the magnetic field generating device 3 and the drawer body 1, preventing the heat of the magnetic field generating device 3 from being directly conducted to the drawer body 1, and reducing the heat conduction rate of the magnetic field generating device 3 to the drawer body 1. In addition, the receiving box 2 is also provided with a damper 21. By opening the damper 21, air is introduced into the receiving box 2 to cool the magnetic field generating device 3, thereby controlling the temperature of the magnetic field generating device 3 to be lower than or equal to a first preset temperature range, and avoiding the magnetic field generating efficiency or the temperature of the drawer body 1 being affected by the excessively high temperature of the magnetic field generating device 3.

[0038] As a specific implementation method, the first preset temperature can be 8°C and the second preset temperature can be 2°C.

[0039] Understandably, the magnetic field generating device 3 applies a magnetic field to the drawer body 1. The magnetic field alters the activity and structural function of polyphenol oxidase, superoxide dismutase, and peroxidase containing metal ion cofactors, thereby inhibiting the respiratory metabolism of fruits and vegetables, reducing nutrient loss, improving sensory quality, and extending shelf life. Furthermore, the magnetic field can also alter the metabolic mechanism of microorganisms, reduce the relative expression level of gene fragments synthesizing bacterial, mold, and fungal toxins, and effectively inhibit the production of microbial toxins, thus achieving magnetic field preservation.

[0040] Optionally, the drawer assembly provided in this embodiment further includes a temperature sensor 4. The temperature sensor 4 is disposed on the magnetic field generating device 3 to detect the temperature of the magnetic field generating device 3. The temperature sensor 4 is communicatively connected to the damper 21. Furthermore, the temperature sensor 4 can be electrically connected to the damper 21, and the damper 21 opens or closes according to the detection result of the temperature sensor 4. The model of the temperature sensor 4 is not limited here; it can be selected as needed. By directly disposing of the temperature sensor 4 on the magnetic field generating device 3, the accuracy of temperature detection of the magnetic field generating device 3 is ensured.

[0041] The damper 21 can be connected to the air supply channel of the refrigerator. When the damper 21 is opened, the air supply channel can supply air into the container 2 to cool the magnetic field generating device 3.

[0042] Optionally, the drawer assembly provided in this application embodiment further includes an ultrasonic sensor 5, which is disposed inside the drawer body 1 to detect the position of the load inside the drawer body 1; a magnetic field generator 3 is movably disposed inside the receiving box 2 and is communicatively connected to the ultrasonic sensor 5. The magnetic field generator 3 is used to move relative to the load according to the detection result of the ultrasonic sensor 5. By movably disposing the magnetic field generator 3 inside the drawer body 1, the accuracy of the magnetic field applied by the magnetic field generator 3 to the load inside the drawer body 1 is further improved, electromagnetic losses caused by the large distance between the magnetic field generator 3 and the load are reduced, and the preservation effect is improved. It is understood that the load in this document refers to the stored items inside the drawer body 1, such as fruits, vegetables, meat products, etc.

[0043] Specifically, the ultrasonic sensor 5 is a sensor that converts ultrasonic signals into other energy signals (usually electrical signals). It uses high-frequency sound waves to detect the position and distance of the load. The ultrasonic sensor 5 includes a transmitter, a receiver, a control unit, and a power supply unit. The transmitter generates and sends ultrasonic waves, and the receiver receives the reflected ultrasonic waves. The ultrasonic sensor 5 can detect the load status inside the drawer body 1. When the ultrasonic sensor 5 is installed on the top inside the drawer body 1 and emits sound waves into the drawer body 1, the position and status of the load inside the drawer body 1 can be analyzed, such as full load, empty load, or half-full load. The model of the ultrasonic sensor 5 is not further specified here.

[0044] Optionally, the receiving box 2 is provided with a guide rail 6, on which the magnetic field generating device 3 is slidably mounted; the drawer assembly also includes a drive component, which is communicatively connected to the ultrasonic sensor 5, and is used to drive the magnetic field generating device 3 to slide. By setting the guide rail 6, the magnetic field generating device 3 is guided and limited, ensuring the running direction of the magnetic field generating device 3. The guide rail 6 can extend along the sliding direction of the drawer body 1, so that the magnetic field generating device 3 can slide along the guide rail 6 to any position of the drawer body 1 in the front-back direction, ensuring that the load at any position inside the drawer body 1 can be covered by the magnetic field.

[0045] It is understandable that the load usually has a certain width. The width information of the load can be detected by the ultrasonic sensor 5. Based on the width information of the load, the magnetic field generator 3 is moved to the position corresponding to the middle of the load, so that the load is in a uniform magnetic field.

[0046] In some examples, the drive element can be a linear motor.

[0047] Optionally, the ultrasonic sensor 5 is also used to detect the volume of the load, and the magnetic field generating device 3 adjusts the on / off ratio based on the detection results of the ultrasonic sensor 5. That is, when the volume of the load is large, it indicates a greater need for preservation, so the on / off ratio of the magnetic field generating device 3 is increased; when the volume of the load is small, it indicates a smaller need for preservation, so the on / off ratio of the magnetic field generating device 3 is decreased. The on / off ratio of the magnetic field generating device 3 is the ratio of the on-time of the magnetic field generating device 3 to 60 minutes; that is, the higher the on / off ratio of the magnetic field generating device 3, the longer the magnetic field action time.

[0048] In one specific implementation, when the load in the display drawer body 1 is less than one-quarter full load, the on / off ratio of the magnetic field generating device 3 is set to 30% to 40%; when the load in the display drawer body 1 reaches one-quarter full load but less than half full load, the on / off ratio of the magnetic field generating device 3 is set to 40% to 50%; when the load in the display drawer body 1 reaches or exceeds half full load, the on / off ratio of the magnetic field generating device 3 is set to 50% to 60%.

[0049] Optionally, the drawer assembly provided in this application embodiment further includes a sterilization module 7, which is disposed within the drawer body 1. The sterilization module 7 is used to release sterilizing active species into the drawer body 1. Specifically, the sterilization module 7 is a low-temperature plasma sterilization module 7. It can be understood that low-temperature plasma sterilization technology is a food cold sterilization technology. When the applied voltage reaches the breakdown voltage, gas molecules are ionized, thereby generating a mixture including electrons, ions, atoms, and atomic groups. The generated active species such as reactive oxygen, reactive nitrogen, ultraviolet radiation, high-energy ions, and charged particles work synergistically to cause the electrostatic repulsion force generated on the surface of microbial cells to exceed the tensile strength of the cell membrane. The cell membrane is mechanically damaged and ruptured, leading to cell death, thereby inhibiting the growth of microorganisms. At the same time, it can degrade chemical pesticides on fruits and vegetables. Among them, the low-temperature plasma sterilization module 7 is particularly suitable for the cold sterilization of fresh and heat-sensitive foods.

[0050] Optionally, the sterilization module 7 can be set to turn off after a first preset time, and then turn on again after a second preset time interval, repeating this cycle to save energy and sterilize. The first preset time can be five to fifteen minutes, and the second preset time can be three to five hours.

[0051] Optionally, the drawer body 1 includes two drawers arranged side by side, with a receiving box 2 adjacent to both drawer bodies 1. A magnetic field generating device 3 is movably disposed within the receiving box 2 to apply a magnetic field simultaneously to both drawer bodies 1, or to one or both of the two drawer bodies 1. That is, two adjacent drawer bodies 1 can share one magnetic field generating device 3, eliminating the need for a separate device for each drawer body 1, thus reducing manufacturing costs. When the magnetic field generating device 3 moves between the two drawer bodies 1, it can simultaneously apply a magnetic field to both drawer bodies 1.

[0052] As an alternative implementation, the drawer body 1 may also include multiple drawers arranged in parallel, that is, multiple drawer bodies 1 share a single magnetic field generating device 3, which will not be further described here.

[0053] Optionally, the container 2 is located at the bottom of the drawer body 1. Since the loads are gradually stacked from the bottom of the drawer body 1 upwards, placing the container 2 at the bottom of the drawer body 1 can reduce electromagnetic losses during the application of the magnetic field by the magnetic field generator 3.

[0054] This application also provides a refrigerator; please refer to [link / reference]. Figure 2 This includes drawer components as described above.

[0055] Optionally, the refrigerator also includes a cabinet, a door, and a detection device. The drawer assembly is located inside the cabinet, and the detection device is used to detect the open / closed state of the door. The detection device is communicatively connected to the magnetic field generator 3. When the door is open, the magnetic field generator 3 is turned off. That is, when the refrigerator door is open, the magnetic field generator 3 stops working to avoid affecting the human body. Of course, when the drawer body 1 is empty, the magnetic field generator 3 is also turned off. The type of detection device is not further limited here; in some examples, it can be an infrared detection device.

[0056] Furthermore, the sterilization module 7 also stops working when the refrigerator door is opened.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
