Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a structure for magnetic energy preservation in freezers. Background Technology

[0002] Freezers, as a common household appliance, primarily rely on low temperatures to effectively extend the shelf life of food. With rising living standards, the demand for food preservation is increasing. However, existing freezers often face problems such as nutrient loss, decreased taste, and shortened shelf life when storing food for extended periods, especially with longer storage times.

[0003] Currently, the technical solutions for extending the shelf life of food in freezers mainly focus on improving the low-temperature performance of freezers and improving air circulation. These measures are subject to storage time and environmental conditions, and may even increase the energy consumption of freezers. Utility Model Content

Detailed Implementation

[0023] The specific implementation of a structure for magnetic energy preservation in a freezer provided by this utility model will be further described in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, a structure for magnetic energy preservation in a freezer includes an upper magnetic field assembly 4 and a lower magnetic field assembly 5. The upper magnetic field assembly 4 is embedded in a groove 301 in the door liner 3 of the door body 1; the lower magnetic field assembly 5 is fixed to the bottom of the outer shell of the cabinet body 2 by a mounting shell 501.

[0025] like Figure 2 As shown, the upper magnetic field assembly 4 includes a first mounting box 401, which is engaged with the groove 301 of the door liner 3 via a snap fastener 4011 (of course, snap fastening is not limited to this; any detachable installation method is acceptable and is not intended to further limit the present invention). A first cover 405 is provided on the side of the first mounting box 401 away from the door liner 3. A first magnetic conductive sheet 402, a first permanent magnet 403, and a first electromagnetic coil 404 are disposed inside the first mounting box 401; wherein, the first magnetic conductive sheet 402 is disposed on the side of the first permanent magnet 403 near the door liner 3; and the first electromagnetic coil 404 is disposed on the side of the first permanent magnet 403 near the first cover 405.

[0026] like Figure 3As shown, the lower magnetic field assembly 5 includes a second mounting box 502, which is snapped onto the mounting shell 501 at the bottom of the cabinet 2 via a snap fastener (of course, snap fastening is not limited to this; any detachable installation method is acceptable and is not intended to further limit the present invention). A second cover 506 is provided on the side of the second mounting box 502 away from the cabinet 2. A second magnetic conductive sheet 503, a second permanent magnet 504, and a second electromagnetic coil 505 are provided inside the second mounting box 502. The second magnetic conductive sheet 503 is located on the side of the second permanent magnet 504 near the mounting shell 501. The second electromagnetic coil 505 is located on the side of the second permanent magnet 504 near the second cover 506. It is worth noting that the arrangement of the first magnetic conductive sheet 402 and the second magnetic conductive sheet 503 can effectively reduce the energy loss of the magnetic field during transmission, thereby improving the magnetic energy utilization efficiency and reducing the amount of magnets used, thus avoiding the problem of increasing the weight of the refrigerator by using too many magnets.

[0027] Preferably, for ease of assembly and disassembly, the first mounting box 401 is snap-fitted to the first cover 405. The second mounting box 502 is snap-fitted to the second cover 506. Of course, the connection method here is not limited to snap-fit; any detachable connection method is acceptable, and this is not intended to further limit the present invention.

[0028] To ensure that the center points of the magnetic conductive sheet, the permanent magnet, and the electromagnetic coil are collinear, and that the direction of the magnetic field introduced by the electromagnetic coil is consistent with the direction of the magnet generated by the permanent magnet, thereby enhancing the magnetic field strength, the first magnetic conductive sheet 402, the first permanent magnet 403, and the first electromagnetic coil 404 are of the same size and their edges are aligned; the second magnetic conductive sheet 503, the second permanent magnet 504, and the second electromagnetic coil 505 are of the same size and their edges are aligned.

[0029] More preferably, the first electromagnetic coil 404, the second electromagnetic coil 505, and the touch switch 6 of the door 1 are all electrically connected to the controller of the freezer (not shown in the figure).

[0030] like Figure 4 As shown, based on the structure provided by this utility model, the specific working principle for achieving the preservation function is as follows:

[0031] First, assuming the freezer's refrigeration system is operating normally, if the touch switch 6 on the freezer door is opened, the door status sensor (not shown in the figure) of the touch switch 6 transmits a signal to the freezer controller. The controller then controls the first electromagnetic coil 404 and the second electromagnetic coil 505 in the upper magnetic field assembly 4 and the lower magnetic field assembly 5 to work in conjunction with the first permanent magnet 403 and the second permanent magnet 504, so that the magnetic fields generated by the upper magnetic field assembly 4 and the lower magnetic field assembly 5 are in the same direction, causing like poles to repel each other. Then, the user can retrieve or store items. When the user closes the freezer door 1 after use, the controller receives the signal that the door 1 is closed. The controller then controls the upper magnetic field assembly 4 and the lower magnetic field assembly 5 to generate magnetic fields in opposite directions, causing opposite poles to attract each other. At the same time, the weighing sensor (not shown in the figure) installed in the cabinet 2 detects the increase in the mass of the contents. If the mass of the contents increases, the controller controls the first electromagnetic coil 404 and the second electromagnetic coil 505 of the upper magnetic field assembly 4 and the lower magnetic field assembly 5 to increase the magnetic field strength; if the mass of the contents remains unchanged, the original magnetic field strength is maintained; if the mass of the contents decreases, the magnetic field strength is reduced.

[0032] Secondly, during the normal operation of the freezer with door 1 closed, the temperature inside cabinet 2 is monitored in real time by a thermostat (not shown in the figure) and a temperature sensor (not shown in the figure) inside cabinet 2. When the temperature inside cabinet 2 is higher than the set temperature, the controller receives a signal and controls the first electromagnetic coil 404 and the second electromagnetic coil 505 of the upper magnetic field component 4 and the lower magnetic field component 5 to increase the magnetic field strength, thereby continuously strengthening the preservation magnetic field inside cabinet 2. When the temperature inside cabinet 2 is lower than the set temperature, the controller receives a signal and sets the activation rate of the electromagnetic coils of the upper magnetic field component 4 and the lower magnetic field component 5 according to different intervals, implementing an intermittent operation mode of the preservation magnetic field. This effectively achieves the food preservation function while also ensuring the optimization of the freezer's energy consumption.

[0033] This invention features an upper magnetic field assembly and a lower magnetic field assembly positioned opposite each other on the inner side of the freezer door lining and the bottom of the freezer exterior, respectively. Through an electromagnetic coil and a magnetically conductive sheet, the static magnetic field generated by the permanent magnet and the dynamic magnetic field generated by the electromagnetic coil are superimposed. This generates a constant magnetic field that directly inhibits the metabolism and reproduction of microorganisms or bacteria, slows down oxidation reactions, inhibits enzymatic reactions that lead to food spoilage, optimizes the magnetic field environment inside the freezer, improves food preservation, and effectively reduces the loss of moisture and nutrients. Compared to traditional preservation methods, this method offers significantly better preservation and is safer and more environmentally friendly.
