Description

Technical Field

[0001] This utility model relates to the field of plasma preservation freezers, specifically to a plasma field effect preservation freezer. Background Technology

[0002] Refrigerator plasma technology is an innovative technology that applies plasma technology to the refrigerator field. Plasma, as a high-energy state of matter composed of a large number of charged particles, has significant bactericidal and disinfecting properties. In refrigerator applications, plasma can effectively inhibit the growth of bacteria and mold, thereby significantly extending the shelf life of food.

[0003] Currently, plasma freezers on the market primarily use plasma generators installed inside the freezer to produce plasma for sterilization. However, this traditional design has significant limitations: firstly, the installation position of the plasma generator is fixed and cannot be adjusted according to actual usage needs; secondly, the plasma radiation range is limited, making it difficult to achieve uniform coverage of the freezer's interior space, resulting in unsatisfactory sterilization effects. Furthermore, the lack of effective plasma emitter fixing devices in existing technology makes equipment maintenance and cleaning difficult. These problems severely restrict the application of plasma technology in refrigeration equipment. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a plasma field effect preservation freezer.

[0005] This utility model is achieved through the following technical solution:

[0006] A plasma field effect preservation freezer includes a freezer body, a plasma generator installed on the upper part of the freezer body, the plasma generator being electrically connected to multiple plasma emitting rods movably disposed inside the freezer body, and the plasma emitting rods being movably connected to multiple shelves disposed inside the freezer body through multiple elastic clamps.

[0007] Alternatively, plasma emitting rods are distributed on both sides inside the freezer body and run longitudinally through multiple shelves.

[0008] Further optionally, the elastic clamp includes a sleeve fixed to the plasma emission rod, with arc-shaped elastic tabs on both sides of the sleeve that can extend and lock onto the shelf.

[0009] Alternatively, the two ends of the arc-shaped elastic sheet are provided with bent portions, and the inner side of the bent portions has a connecting groove that can be locked onto the shelf connecting rod.

[0010] Alternatively, the plasma generator can be electrically connected to a controller located on the upper part of the freezer body.

[0011] Compared with existing technologies, the advantages of this utility model are: by setting up a plasma emitting rod and an elastic clamp structure that are connected to and movable in the plasma generator, this utility model realizes the flexible adjustment and stable installation of the plasma generator, solves the problems of fixed installation and limited radiation range in traditional designs, and has the advantages of good sterilization effect and flexible and convenient use.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-3 As shown, this application proposes a plasma field effect preservation freezer, including a freezer body, a plasma generator installed on the upper part of the freezer body, the plasma generator being electrically connected to multiple plasma emitting rods movably disposed inside the freezer body, and the plasma emitting rods being movably connected to multiple shelves disposed inside the freezer body through multiple elastic clamps.

[0018] The plasma generator can use a high-frequency AC power supply or a pulsed DC power supply as the excitation source, with a preferred power range of 50-200W. The plasma emission rod can be made of stainless steel or titanium alloy, and a ceramic insulation layer can be applied to its surface to prevent leakage. The elastic clamps can be made of spring steel, and their elastic deformation should be adjustable within a range of 10-20mm. The shelves can be made of metal mesh structure, and their surface can be treated with anti-corrosion coating.

[0019] This technical solution solves the problem of uneven plasma distribution in existing technologies by combining a plasma generator with an adjustable plasma emitting rod. The plasma generator produces plasma, which is then emitted by the plasma emitting rod for sterilization. The plasma emitting rod is movably connected to the shelf via flexible clamps, allowing its position to be adjusted according to storage needs, ensuring uniform plasma distribution within the freezer's interior space. The flexible connection method ensures both installation stability and ease of position adjustment. Compared to fixed installation methods, this structure significantly increases the plasma coverage area, thereby enhancing the sterilization effect.

[0020] Furthermore, this application also proposes that plasma emitting rods are distributed on both sides inside the freezer body and extend longitudinally through multiple shelves.

[0021] Specifically, the plasma emitting rods achieve a uniform distribution of plasma within the freezer's interior space by longitudinally passing through the shelves. As a preferred embodiment, the plasma emitting rods can be symmetrically arranged along both sides of the freezer's inner wall, forming a parallel arrangement. Furthermore, the emitting rods can be made of stainless steel or conductive ceramic material, preferably with a diameter ranging from 20-40 mm, and a length matching the height of the freezer's interior cavity. The longitudinal passage is achieved by passing through adjacent connecting rods within the shelf.

[0022] Therefore, this technical solution effectively solves the problem of uneven plasma radiation in existing technologies through its double-sided arrangement and longitudinally penetrating structural design. Compared with the traditional single-sided installation method, the double-sided arrangement allows the plasma field to cover the entire storage space, significantly improving the sterilization effect, especially for areas far from the emission source. The design that longitudinally penetrates multiple shelves ensures that each storage layer receives sufficient plasma irradiation, while avoiding radiation dead zones caused by shelf obstruction. This structure maintains installation stability while achieving a three-dimensional uniform distribution of the plasma field, thereby improving the overall sterilization and preservation effect.

[0023] Furthermore, this application also proposes that the elastic clamp includes a sleeve fixed to the plasma emission rod, and the sleeve has arc-shaped elastic pieces on both sides that can extend and retract and lock onto the shelf.

[0024] Specifically, the clamp can be made of metal or high-strength plastic and is fixed to the surface of the plasma emission rod by bolts. The arc-shaped elastic sheet is preferably made of spring steel, with both ends bent inward to form an arc structure, maintaining an outward expanding elastic force in its natural state. When installation is required, the arc-shaped elastic sheet is pressed to contract it, and after aligning it with the shelf, the pressure is released, and the elastic restoring force is used to lock the arc-shaped elastic sheet into place on the edge of the shelf.

[0025] Therefore, this technical solution achieves rapid assembly and disassembly, as well as a secure connection, between the plasma emitter and the shelf through a unique design of elastic clamps. The extensibility of the arc-shaped elastic sheet allows it to adapt to shelf sizes of different specifications, while the clamp's fixing structure ensures that the plasma emitter will not shift under vibration. Compared to the screw-based fixing method used in existing technologies, this solution significantly improves the convenience of equipment maintenance and avoids thread damage caused by frequent disassembly and assembly. The elastic contact rather than rigid connection also effectively absorbs mechanical vibrations during freezer operation, extending the service life of the plasma emitter.

[0026] Furthermore, this application also proposes that the two ends of the arc-shaped elastic sheet are provided with bent portions, and the inner side of the bent portions has a connecting groove that can be locked onto the shelf connecting rod.

[0027] Specifically, the bending section is formed by stamping a thin metal sheet, with a bending angle of 90°-120°. The connecting groove has a U-shaped structure, and the groove width is slightly smaller than the diameter of the shelf connecting rod to achieve an interference fit. As a preferred embodiment, the bending section and the arc-shaped elastic sheet are integrally formed, using 304 stainless steel or phosphor bronze as the material, with a thickness controlled within the range of 0.3-0.5mm. Furthermore, the inner wall of the connecting groove can be equipped with anti-slip textures or rubber pads to enhance the stability of the connection.

[0028] Therefore, this technical solution achieves rapid positioning and reliable connection between the plasma emitter and the shelf through the coordinated design of the bending section and the connecting slot. Compared with the simple elastic clamping structure in existing technologies, this design effectively prevents displacement caused by vibration during use, ensuring that the plasma emitter is always at the optimal radiation angle. Specifically, the structural design of the bending section allows the elastic sheet to generate directional restoring force when deformed under pressure, while the precise fit between the connecting slot and the shelf linkage prevents radial movement. The synergistic effect of both maintains ease of installation and improves the impact resistance of the connection structure.

[0029] Furthermore, this application also proposes that the plasma generator be electrically connected to the controller located on the upper part of the freezer body.

[0030] Specifically, the controller can be located within the top control panel of the freezer body and electrically connected to the plasma generator via wires. As a preferred embodiment, the controller can employ a microprocessor control unit to adjust the operating parameters of the plasma generator via PWM signals. Furthermore, the controller can be set to multiple operating modes, such as continuous operation mode and intermittent operation mode, achieving different sterilization effects by adjusting the discharge frequency and intensity of the plasma generator. In addition, the controller can also be equipped with a temperature sensor interface to automatically adjust the output power of the plasma generator according to the internal temperature of the freezer.

[0031] Therefore, by electrically connecting the plasma generator to the controller, precise control of the plasma generator is achieved. Compared with the prior art, this technical solution solves the problem of the non-adjustable operating parameters of the plasma generator, and can adjust the plasma generation intensity in real time according to the internal environment of the freezer, thereby improving the sterilization effect and reducing energy consumption. The basic principles, main features and advantages of this utility model have been shown and described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model.
