Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigeration device. Background Art

[0002] During storage, meat, fruits, and vegetables are prone to quality deterioration, resulting in poor taste and nutrient loss, as well as yellowing and wilting of fruits and vegetables. High-end ingredients, in particular, experience significant degradation in appearance and taste when stored in ordinary refrigerators, impacting the consumer experience and causing food waste.

[0003] In recent years, new technologies have emerged in the refrigerator industry to address these food preservation issues. Studies have shown that electric fields can manipulate water molecules in food, causing resonance. This can inhibit cellular respiration, induce stress and lead to the accumulation of soluble sugars, inhibit enzyme activity, slow protein oxidation, and disrupt bacterial structure, thereby slowing nutrient loss, maintaining flavor, and extending shelf life. Electric fields typically take the form of bipolar plates, creating a uniform field between two parallel plates. However, when used in refrigerators, this can lead to the bottom plate becoming disconnected, compromising safety. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "including" and "having" in the embodiments of this application and any variations thereof are intended to cover non-exclusive inclusions.

[0036] Studies have shown that electric fields can regulate water molecules in food ingredients, causing resonance, thereby inhibiting the respiration of fruit and vegetable cells, generating adverse stress and accumulating soluble sugars, inhibiting enzyme activity and delaying protein oxidation, and destroying bacterial structure, thereby delaying nutrient loss, maintaining taste and extending shelf life.

[0037] In related technologies, the common form of an electric field is a bipolar plate, with a uniform field strength formed between two parallel plates. One plate is placed at the top of the fresh-keeping drawer, and the other at the bottom. The plate at the bottom of the drawer moves with the drawer, and the plates themselves are connected to an external power supply via wires. This makes the bottom plate prone to disconnection, which can easily cause leakage and pose a safety hazard to users.

[0038] For this, please refer to Figure 1-Figure 5 An embodiment of the present application provides a refrigeration device, including a main body, a storage container 100 and an electric field generating device 200.

[0039] The body is the main structure of the refrigeration device, which has a storage compartment. The storage compartment can be a refrigerator compartment or a freezer compartment. The temperature in the refrigerator compartment is lower than room temperature and higher than freezing point. It should be noted that the refrigeration device can have a refrigerator compartment and a freezer compartment, or can have only a refrigerator compartment or a freezer compartment.

[0040] Please refer to Figure 1 and Figure 2 The storage container 100 is disposed in the storage chamber and is movable relative to the main body. The storage container 100 has a fresh-keeping space 100a. Food can be placed in the fresh-keeping space 100a. The structure of the storage container 100 is not limited. For example, the storage container 100 can be a drawer-like structure that can be pulled out to facilitate the placement and removal of food in the fresh-keeping space 100a.

[0041] The electric field generating device 200 is disposed within the main body and is used to generate an electric field that acts upon the fresh-keeping space 100a. It is understood that the electric field generating device 200 requires connection to an external power source to generate the electric field. By disposing the electric field generating device 200 within the main body, the electric field generating device 200 does not move with the storage container 100, thereby preventing the external wires connected to the external power source from moving.

[0042] In the above embodiment, the storage container 100 is placed within the storage compartment, and the electric field generator 200 is mounted within the main body. This generates an electric field within the fresh-keeping space 100a of the storage container 100, thereby slowing nutrient loss, maintaining food's flavor, and extending its shelf life. Because the electric field generator 200 is mounted within the main body, it does not move with the storage container 100, thus preventing the external power supply wires from moving. This eliminates the risk of electrical leakage caused by disconnection and improves safety.

[0043] The relative position of the electric field generating device 200 and the body is not limited, for example, it can be set on one side of the storage container 100 in the front-to-back direction, one side in the left-to-right direction, or one side in the top-to-bottom direction.

[0044] In some embodiments, the storage compartment is a refrigerator, and the electric field generating device 200 is located on top of the storage container 100. It should be noted that the refrigerator has a power interface, which is generally located in the top area of ​​the refrigerator. Placing the electric field generating device 200 on top of the storage container 100 can reduce the length of external wires and reduce costs.

[0045] In some embodiments, the electric field generating device 200 is located at the bottom of the storage container 100. It is understandable that the food placed in the fresh-keeping space is supported by the bottom surface of the fresh-keeping space. Locating the electric field generating device 200 at the bottom of the storage container 100 can bring the electric field generating device 200 closer to the food. In this way, while meeting the optimal field strength, the power supply voltage of the electric field generating device can be reduced, thereby reducing energy consumption.

[0046] The connection structure between the electric field generating device 200 and the main body is not limited. In some embodiments, the main body includes a cover plate 310 and an insulation layer. The cover plate 310 is located on top of the storage container 100 and is used to cover the fresh-keeping space 100a. It is understood that the fresh-keeping space 100a is open upward, and the storage container 100 can be moved under the cover plate 310 to cover the opening, or moved out to open the opening for convenient storage and access of food.

[0047] The electric field generating device 200 is arranged on the side of the cover 310 away from the storage container 100, that is, Figure 1The heat-insulating layer is formed on the side of the cover plate 310 facing away from the storage container 100 and covers the electric field generating device 200. In other words, the electric field generating device 200 is enclosed between the cover plate 310 and the heat-insulating layer, and the user cannot directly contact the electric field generating device 200.

[0048] The thermal insulation layer can be obtained through a foaming process or can be a filled foam material.

[0049] For further information, please refer to Figure 2 In some embodiments, the side of the cover plate 310 facing away from the storage container 100 has a plurality of protruding hooks 311. The electric field generating device 200 is disposed on the side of the cover plate 310 facing away from the storage container 100, and the hooks 311 can be secured to the electric field generating device 200. Specifically, the hook portions of the hooks 311 can be pressed against the surface of the electric field generating device 200 facing away from the cover plate 310, thereby achieving a quick connection between the electric field generating device 200 and the cover plate 310. This connection can prevent the position of the electric field generating device 200 relative to the cover plate 310 from changing during assembly, and the installation process is simple and convenient, with high assembly efficiency.

[0050] The plurality of hooks 311 are distributed on at least two opposite sides of the electric field generating device 200. In some embodiments, the plurality of hooks 311 are distributed on both sides of the electric field generating device 200 along the width direction and on one side along the length direction, that is, Figure 1 The electric field generating device 200 can enter from the other side in the length direction and be snapped into each hook 311 to achieve connection and positioning.

[0051] The electric field generating device 200 can be arranged in the middle of the cover 310 to improve the uniformity of the field strength in the fresh-keeping space 100a. Specifically, the electric field generating device 200 has a monopolar plate 210, which is used to generate an electric field. The center of the monopolar plate 210 roughly coincides with the center of the cover 310. It can be understood that compared with the structure in which the bipolar plate generates an electric field through two plates, the monopolar plate generates an electric field through one plate, so the manufacturing cost will be relatively lower and the assembly will be simpler. Among them, the electric field generating device 200 is a roughly rectangular body, including a long side and a short side, and the long side is parallel to the two sides in the width direction of the cover 310, that is, Figure 1 The two sides in the left and right directions are parallel to the two sides in the length direction of the cover plate 310, that is, Figure 1 On both sides of the front-back direction.

[0052] Furthermore, to restrict the layout of the external wires of the electric field generating device 200, in some embodiments, a wire clamp 312 is provided on the edge of the cover 310 facing away from the storage container 100. The wire clamp 312 is located in the extension path of the external wires. Thus, the external wires extending from the middle of the cover 310 pass through the wire clamp 312 at the edge of the cover 310 and are connected to the external power source. The wire clamp 312 can limit the position of the external wires, allowing the external wires to be arranged along a predetermined path, improving the consistency and aesthetics of the external wire layout.

[0053] The following is combined with Figure 3-5 The structure of the electric field generating device 200 will be described in detail.

[0054] Please refer to Figure 3 In some embodiments, the electric field generating device 200 includes a monopolar plate 210 and a power module 220. The power module 220 is electrically connected to the monopolar plate 210 and is used to output alternating current (AC) with a voltage between 132V and 232V. It is understood that under the action of the AC current of the aforementioned voltage on the monopolar plate 210, oscillating waves are emitted from both sides of the thickness direction of the monopolar plate 210 to form a uniform electric field in the fresh-keeping space 100a, with a field strength within the range of 350-750V / m. Experiments have determined that in an electric field of the aforementioned field strength, the loss of nutrients in food can be delayed, the taste can be maintained, and the shelf life can be extended.

[0055] It should be noted that the output voltage of the power module 220 is related to the distance between the monopolar plate 210 and the fresh-keeping space 100a, as well as the size of the fresh-keeping space. The greater the distance and the larger the fresh-keeping space, the higher the voltage. In some specific embodiments, the output voltage of the power module 220 is 132V, 150V, 182V, 150V, or 232V. The output voltage of the power module 220 has a frequency of 18kHz, and the power module 220 receives a 12V DC input.

[0056] To improve the uniformity of the electric field, please refer to Figure 4 and Figure 1 In some embodiments, the unipolar plate 210 is disposed parallel to the bottom surface of the fresh-keeping space 100a. Thus, when food is placed in the fresh-keeping space 100a and supported by the bottom surface of the fresh-keeping space 100a, the food can be more evenly distributed because the unipolar plate 210 is parallel to the bottom surface of the fresh-keeping space 100a.

[0057] Please refer to Figure 3 and Figure 4In some embodiments, the electric field generating device 200 includes a storage box 230 having a storage cavity 230a within which the unipolar plate 210 is disposed. The storage box 230 is made of an insulating material. It will be appreciated that the use of an insulating material in the storage box 230 and the placement of the unipolar plate 210 within the storage cavity 230a of the storage box 230 can prevent electrical leakage from the unipolar plate 210 and improve user safety. The insulating material can be plastic.

[0058] The storage box 230 includes a box body 231 and a box cover 232. The box body 231 and the box cover 232 are combined to form a storage cavity 230a. In this way, the monopolar plate 210 can be easily placed in the storage cavity 230a.

[0059] The box body 231 and the box cover 232 may be connected in any manner. For example, the box body 231 and the box cover 232 may be connected by fasteners.

[0060] In some embodiments, the box body 231 and the box cover 232 are engaged with each other to enclose the receiving cavity 230a. The above-mentioned engagement method can improve the assembly efficiency of the box body 231 and the box cover 232.

[0061] The box body 231 may have an upward opening, the opening of the box body 231 is connected to the receiving cavity 230 a , and the box cover 232 is disposed on the box body 231 to close the opening, that is, to close the receiving cavity 230 a .

[0062] To prevent water from leaking into the receiving cavity from the snap-on position. Figure 3-Figure 5 In some embodiments, the box cover 232 includes a cover body 2321 and a latching protrusion 2322. The latching protrusion 2322 is connected to the edge of the cover body 2321 and protrudes toward the box body 231. The outer wall of the box body 231, at least on the side away from the cover body 2321, is recessed inward to form a latching groove 231a, which is engaged with the latching protrusion 2322. In this way, under the action of gravity, water can flow downward along the latching protrusion 2322, thereby preventing the safety hazard caused by condensation of water vapor and seeping into the storage chamber 230a.

[0063] It should be noted that, when the monopolar plate 210 is powered on, it reacts with oxygen in the air and produces ozone, which is harmful to the human body and can easily oxidize components in the refrigeration equipment, such as the inner tank of the main body.

[0064] To limit the generation and outflow of ozone, in some embodiments, the storage box 230 has a sealed storage chamber 230a, and the monopolar plate 210 is disposed within the storage chamber 230a. The sealed storage chamber 230a prevents the air inside the storage chamber 230a from flowing and exchanging with the outside air, thereby preventing the small amount of ozone generated from entering the storage chamber.

[0065] The sealing structure of the receiving cavity 230a is not limited. In some embodiments, please refer to Figure 4 and Figure 5 The top surface of the side wall of the box body 231 is provided with an annular groove 231b surrounding the receiving cavity 230a. The annular groove 231b can be a closed annular groove 231b connected end to end.

[0066] The storage box 230 includes a sealing ring 233, which is disposed in the annular groove 231b. It is understood that the sealing ring 233 can be an elastic structure that can be deformed under external force to fully contact the wall of the annular groove 231b to achieve a sealing function.

[0067] The lid 232 has an annular protrusion 2323 facing the body 231. The lid 232 is positioned over the body 231, with the protrusion 2323 pressing against the sealing ring 233. This elastically deforms the sealing ring 233, sealing the connection between the lid 232 and the body 231. This seals the storage chamber 230a, preventing air from flowing and exchanging with the outside air, and thus preventing the small amount of ozone generated from entering the storage chamber. Furthermore, the annular protrusion 2323 enhances the overall strength of the lid 232, reducing the likelihood of damage during transportation and assembly.

[0068] The number of the annular grooves 231b is not limited. Figure 4 The box body 231 shown in FIG is provided with an annular groove 231 b. In other embodiments, a plurality of annular grooves 231 b may be provided at intervals along the thickness direction of the side wall of the box body 231. Each annular groove 231 b corresponds to an annular protrusion 2323.

[0069] It is understandable that the power module 220 can be disposed in the receiving cavity 230 a , so that the power module 220 can be sealed by the sealed receiving cavity 230 a , thereby reducing the waterproof structure requirements of the power module 220 .

[0070] For other embodiments, please refer to Figure 3 and Figure 4 The box body 231 includes a first region having a storage cavity 230a and a second region, with the power module 220 disposed in the second region. Specifically, the box body 231 includes a bottom plate portion and a side ring portion. The side ring portion protrudes from the bottom plate portion and forms the storage cavity 230a with the side ring portion being located in the first region.

[0071] Since the height dimension of the power module 220 is relatively large, by setting it outside the storage cavity 230a, the volume of the storage cavity 230a can be reduced, saving space. Moreover, since the height difference between it and the monopolar plate 210 is avoided, the top surface of the box cover 232 can be set as a flat structure, thereby facilitating the manufacture of its molding mold.

[0072] Furthermore, in order to achieve waterproof sealing of the power module 220, in some embodiments, the power module 220 is sealed by glue potting to prevent moisture intrusion and avoid circuit short circuit or corrosion.

[0073] Please refer to Figure 3 and Figure 4 The power module 220 can be fastened to the second region. Connecting ears 221 are formed on opposite sides of the power module 220, and the housing 231 has threaded posts 2313 located in the second region. During assembly, the connecting ears 221 are placed on the threaded posts 2313, and fasteners pass through the connecting ears 221 and thread onto the posts 2313, thereby securing the power module 220 to the housing 231.

[0074] It is understood that the unipolar plate 210 is located within the storage cavity 230a. In some embodiments, the box body 231 includes a bottom wall and a supporting protrusion 2311 provided on the bottom wall and protruding from the bottom wall. The supporting protrusion 2311 can support the unipolar plate 210, thereby creating a gap between the bottom wall of the box body 231 and the unipolar plate 210. In operation, when the unipolar plate 210 is energized and generates an electric field, generating heat, the gap allows air to flow in for heat exchange, thereby preventing localized overheating.

[0075] The number of the support protrusion 2311 is not limited, for example, one support protrusion 2311 may be provided, and its shape is annular. In some embodiments, a plurality of support protrusions 2311 are provided, and the plurality of support protrusions 2311 are arranged in parallel and at intervals.

[0076] The box body 231 is integrally formed. For example, the support protrusion 2311 is directly injection-molded on the bottom wall of the box body 231 .

[0077] In order to limit the horizontal position of the monopolar plate 210, in some embodiments, please refer to Figure 4 The monopolar plate 210 has a through-hole and includes positioning posts 2312 formed on the housing 231. The positioning posts 2312 are located within the receiving cavity 230a and can extend into the through-hole to limit the horizontal movement of the monopolar plate 210. Furthermore, the positioning posts 2312 can quickly locate the position of the monopolar plate 210 during assembly.

[0078] It is understandable that a wire is connected between the power module 220 and the monopolar plate 210 , and a wire groove is provided on the storage box 230 for the wire to pass through.

[0079] Furthermore, a seal is provided at the wire channel to seal between the wire and the wire channel to prevent air from escaping the channel. In some embodiments, the unipolar plate 210 has a metal plug terminal 211. One end of the wire extending into the receiving cavity 230a is connected to the metal plug terminal 211 to achieve electrical connection between the power module 220 and the unipolar plate 210.

[0080] In some embodiments, the material of the monopolar plate 210 is metal. Specifically, the metal may be stainless steel, which is easy to process and has good corrosion resistance.

[0081] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
