Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to a radio frequency defrosting device and a refrigerator. Background Technology

[0002] Frozen food materials can be thawed using radio frequency (RF) heating. RF heating avoids the problem of slow heating speed caused by traditional heating methods, which heat from the outside in and are limited by the thermal conductivity of the food itself. It can quickly raise the temperature of food materials to the required temperature.

[0003] In related technologies, the output part of radio frequency heating is an electrode plate. The installation of the electrode plate has technical problems such as complicated assembly process and poor assembly efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a radio frequency defrosting device and a refrigerator, aiming to at least partially solve the technical problems of complex assembly procedures and poor assembly efficiency during the installation of electrode plates.

[0005] The technical solution of this utility model is as follows:

[0006] A radio frequency defrosting device includes: a housing having a radio frequency cavity and a defrosting cavity for containing food; an electrode plate disposed within the radio frequency cavity and having multiple notches on its circumferential surface; and multiple first support members disposed within the radio frequency cavity, with the middle portions of the multiple first support members correspondingly embedded in the multiple notches.

[0007] In some implementations, the first support member has a mounting groove in the middle, and the opening wall of the notch is embedded in the mounting groove.

[0008] In some embodiments, the first support member includes: a first support portion; a second support portion; and a third support portion, one end of which is connected to the first support portion and the other end of which is connected to the second support portion, wherein the third support portion is embedded in the notch; wherein the diameter of the first support portion and the diameter of the second support portion are both greater than the width of the notch, and the diameter of the third support portion is less than or equal to the width of the notch.

[0009] In some implementations, the length of the third support portion matches the thickness of the electrode plate.

[0010] In some implementations, the housing is provided with a shield to form the radio frequency cavity and the defrosting cavity.

[0011] In some implementations, one end of the first support abuts against the shielding member, and the other end abuts against the bottom wall of the radio frequency cavity.

[0012] In some implementations, the electrode plate has a groove.

[0013] In some implementations, the radio frequency defrosting device further includes a power amplifier input component electrically connected to the electrode plate.

[0014] In some implementations, the radio frequency defrosting device further includes a second support member, with its two ends connected to the bottom wall of the radio frequency cavity and the electrode plate, respectively.

[0015] Based on the same inventive concept, this application also provides a refrigerator, including the aforementioned radio frequency defrosting device.

[0016] The beneficial effects of this utility model include at least the following:

[0017] Because the enclosure has an RF cavity and a defrosting cavity for holding food, and the electrode plates are located inside the RF cavity, the RF cavity provides a physical protective layer for the electrode plates, preventing damage to the electrode plates from external mechanical impacts or accidental collisions, and extending the service life of the electrode plates.

[0018] Because the electrode plate has multiple notches on its circumference, and multiple first support members are located inside the RF cavity, with the center of each first support member corresponding to one of the notches, when installing the electrode plate into the RF cavity, the center of the first support member is inserted into the corresponding notch, and the electrode plate is supported by the first support member to achieve installation of the electrode plate in the RF cavity. No screws are required, which shortens the installation time and improves the installation efficiency. It also eliminates the need for special tools, reducing tool costs. Operators only need to simply place the first support member into the notch, which reduces the installation difficulty. Moreover, when the electrode plate needs maintenance, replacement, or upgrade, the electrode plate can be easily removed by simply taking out the first support member from the notch, without removing screws. The operation is simple and quick, shortening equipment maintenance time and improving equipment availability and production efficiency. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0040] In related technologies, the electrode plates are fixed to the bottom of the corresponding housing by multiple spaced screws. The screws need to be removed and installed one by one between the electrode plates and the housing. Especially when the internal space of the equipment is small or the electrode plate is large, it is difficult for operators to complete the installation efficiently. Specific screwdrivers or power tools of a certain size are required. If the tools are not compatible or the operation is improper, it is easy to cause the screws to strip or damage the surface of the electrode plates. Moreover, tightening multiple screws one by one increases the assembly time and affects efficiency.

[0041] To address the aforementioned technical issues, the applicant has designed a radio frequency defrosting device and a refrigerator, which uses a first support member to be embedded in multiple notches in a corresponding manner to support the electrode plates. The specific details of the radio frequency defrosting device are now further described with reference to the accompanying drawings.

[0042] Figure 1 These are schematic diagrams of the structure of the electronic control device in some embodiments; Figure 2 for Figure 1 Cross-sectional view of the radio frequency defrosting device; Figure 3 for Figure 2 A schematic diagram showing the fit between the electrode plate and the first support member of the radio frequency defrosting device. (Combined with...) Figure 1 , Figure 2 and Figure 3 The radio frequency defrosting device according to this application includes: a housing 10, an electrode plate 20, and a plurality of first support members 30. The housing 10 has a radio frequency cavity 11 and a defrosting cavity 12 for containing food. The electrode plate 20 is disposed in the radio frequency cavity 11, and a plurality of notches 21 are formed on its peripheral surface. The plurality of first support members 30 are all disposed in the radio frequency cavity 11, and the middle portions of the plurality of first support members 30 are correspondingly embedded in the plurality of notches 21.

[0043] Since the housing 10 has an RF cavity 11 and a defrosting cavity 12 for containing food, and the electrode plate 20 is located in the RF cavity 11, the RF cavity 11 contains the electrode plate 20, providing a physical protective layer for the electrode plate 20, preventing external mechanical impact or accidental collision from damaging the electrode plate 20, and extending the service life of the electrode plate 20.

[0044] Since the electrode plate 20 has multiple notches 21 on its circumferential surface, and multiple first support members 30 are all located inside the radio frequency cavity 11, with the middle parts of the multiple first support members 30 correspondingly embedded in the multiple notches 21, when the electrode plate 20 is to be installed into the radio frequency cavity 11, the middle part of the first support member 30 is embedded in the corresponding notch 21, and the electrode plate 20 is supported by the first support member 30 to achieve the installation of the electrode plate 20 in the radio frequency cavity 11. No screws are required, which shortens the installation time and improves the installation efficiency. It also eliminates the need for professional tools, reducing tool costs. Operators only need to simply put the first support member 30 into the notch 21, which reduces the installation difficulty. Moreover, when the electrode plate 20 needs maintenance, replacement, or upgrade, the electrode plate 20 can be easily removed by simply taking the first support member 30 out of the notch 21 without removing screws. The operation is simple and quick, shortens the equipment maintenance time, and improves the availability and production efficiency of the equipment.

[0045] In related technologies, screw-mounting installation methods can easily damage the RF cavity 11 and electrode plate 20 during disassembly and assembly if not handled properly, such as causing deformation of the screw holes or scratches on the surface of the electrode plate 20. In some embodiments, the first support member 30 is embedded in the notch 21 to support the electrode plate 20. It is only necessary to move the first support member 30 along the axial direction of the notch 21, allowing it to enter the notch 21 through the opening or leave the notch 21. This makes the disassembly and assembly process relatively gentle, reducing potential damage to the electrode plate 20 caused by installation and disassembly operations and extending the service life of the electrode plate 20.

[0046] In related technologies, during screw installation, the tightening force of the screws may generate stress on the electrode plate 20 and the RF cavity 11, causing deformation of the electrode plate 20 or changes in the structure of the RF cavity 11, thereby affecting the performance of the device. In some embodiments, the first support member 30 is embedded in the notch 21 to support the electrode plate 20, which does not require stress to be generated on the electrode plate 20 or the RF cavity 11, avoids the concentration of local stress, reduces the impact of stress on the device performance, and helps to maintain the stability and reliability of the device.

[0047] In some embodiments, the cooperation between the first support 30 and the notch 21 can provide more precise positioning, ensuring that the electrode 20 is installed in the radio frequency cavity 11 in an accurate position.

[0048] Combination Figure 3 In some embodiments, to ensure the stability of the first support member 30 supporting the electrode plate 20, multiple first support members 30 are evenly spaced at equal angles. When the electrode plate 20 is subjected to external force, the evenly spaced first support members 30 can evenly distribute the force on the electrode plate 20 to each support point. The force borne by each first support member 30 is relatively small and more balanced, avoiding the situation where the first support member 30 is damaged or the electrode plate 20 is deformed due to excessive local force. Moreover, the evenly spaced first support members 30 form a stable support structure, which can improve the overall stiffness and stability of the electrode plate 20 system, enabling it to maintain good structural integrity and reduce swaying and deformation when subjected to dynamic loads such as vibration and impact.

[0049] Figure 4 for Figure 3 Side view; Figure 5 for Figure 4 Enlarged view of point A; Figure 6 for Figure 3 A schematic diagram of the first support component of the radio frequency defrosting device. (Combined with...) Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, to enable the first support member 30 to support the electrode plate 20, a mounting groove 31 is provided in the middle of the first support member 30. The opening wall of the notch 21 is embedded in the mounting groove 31. The engagement of the opening wall of the notch 21 with the mounting groove 31 provides a clear positioning reference for the installation of the electrode plate 20 and the first support member 30. During the installation process, the operator only needs to align the opening wall of the notch 21 with the mounting groove 31 and insert it to quickly and accurately complete the positioning of the electrode plate 20 and the first support member 30, thereby improving installation efficiency and reducing installation errors and rework caused by inaccurate positioning.

[0050] During the process of embedding the notch 21 into the mounting groove 31, no complicated tools or cumbersome operating steps are required; the connection between the electrode plate 20 and the first support member 30 can be achieved with a simple embedding action. Compared with traditional methods such as screw fixing, this saves installation time and labor costs, and can significantly improve production efficiency, especially in large-scale production. Moreover, the sidewall of the mounting groove 31 can effectively constrain the notch 21, preventing the electrode plate 20 from shaking or shifting under force, ensuring the stability of the electrode plate 20 within the RF cavity 11, thereby improving the operational stability of the device.

[0051] Combination Figure 6 In some embodiments, to enable the first support member 30 to support the electrode plate 20, the first support member 30 includes a first support portion 32, a second support portion 33, and a third support portion 34. One end of the third support portion 34 is connected to the first support portion 32, and the other end is connected to the second support portion 33. The third support portion 34 is embedded in the notch 21. The diameters of the first support portion 32 and the second support portion 33 are both greater than the width of the notch 21, and the diameter of the third support portion 34 is less than or equal to the width of the notch 21.

[0052] Since the diameter of the third support portion 34 is less than or equal to the width of the notch 21, the third support portion 34 can smoothly enter the notch 21 during the process of embedding it, thereby installing the first support member 30 in the corresponding position. During disassembly, the third support portion 34 can be directly removed from the notch 21, and the first support member 30 can also be easily removed from the notch 21, improving the convenience of installation and disassembly and reducing operational difficulty and cost.

[0053] Since the diameters of the first support portion 32 and the second support portion 33 are both larger than the width of the notch 21, after the third support portion 34 is embedded in the notch 21, the first support portion 32 and the second support portion 33 can be located on opposite sides of the electrode plate 20. The first support portion 32 and the second support portion 33 can clamp the electrode plate 20, playing a role in restriction and support. The first support portion 32 and the second support portion 33 can withstand forces from different directions, preventing the electrode plate 20 from moving or shaking when subjected to force, providing stable support for the electrode plate 20, and ensuring the normal operation of the entire system.

[0054] In some embodiments, the first support portion 32, the second support portion 33, and the third support portion 34 can be integrally formed, simplifying the original multi-step split production process into a one-time molding, reducing the number of molds, production steps, and production time, and also reducing production costs. Moreover, there are no additional connecting structures (such as screws, rivets, etc.) between the first support portion 32, the second support portion 33, and the third support portion 34, ensuring the stability of the connection, and also making the material continuity between the first support portion 32, the second support portion 33, and the third support portion 34 better, the stress distribution more uniform, and the ability to better disperse and bear stress when subjected to external forces, thereby improving the strength of the entire structure.

[0055] In some embodiments, in order to ensure the stability of the electrode plate 20 installation, the length of the third support 34 is matched with the thickness of the electrode plate 20. After the third support 34 is embedded in the notch 21, the first support 32 and the second support 33 can clamp the electrode plate 20, effectively preventing the electrode plate 20 from shaking after installation and ensuring the stability of the electrode plate 20 installation.

[0056] During installation, since the length of the third support 34 matches the thickness of the electrode plate 20, the third support 34 can be precisely embedded in the notch 21 of the electrode plate 20, which plays a role in precise positioning. This ensures that the electrode plate 20 is in the correct position and posture during installation, reduces installation errors, and improves the accuracy and efficiency of installation.

[0057] If the third support portion 34 is too short, the first support portion 32 and the second support portion 33 may exert excessive pressure on the electrode plate 20 during the process of embedding the third support portion 34 into the notch 21, causing the electrode plate 20 to deform or be damaged. Conversely, if the length is too long, a large gap will be generated between the electrode plate 20 and the first support portion 32 and the second support portion 33, affecting the stability and reliability of the support. Matching the length of the third support portion 34 with the thickness of the electrode plate 20 can avoid these two extreme situations, ensuring that the electrode plate 20 will not be subjected to excessive pressure or loosening during installation.

[0058] Figure 7 for Figure 3 A schematic diagram of the electrode plate structure of the radio frequency defrosting device. (Combined with...) Figure 7In some embodiments, to ensure the structural strength of the electrode plate 20, a groove 22 is formed in the electrode plate 20. The groove 22 can change the stress distribution of the electrode plate 20. When the electrode plate 20 is subjected to bending force, the presence of the groove 22 changes the cross-sectional shape of the electrode plate 20 in the direction of force, increasing the moment of inertia of the cross-section. According to the principles of mechanics of materials, the increased moment of inertia enhances the electrode plate 20's resistance to bending deformation. For example, when subjected to external pressure or tension, the electrode plate 20 with the groove 22 is less prone to bending deformation than the electrode plate 20 without the groove, thereby improving the overall structural strength of the electrode plate 20. The groove 22 is not a through slot; its shape, position, and number can be arranged according to actual needs.

[0059] When the electrode plate 20 is heated, thermal stress may be generated due to the difference in the coefficient of thermal expansion of different parts. The groove 22 provides a buffer space for the thermal expansion of the electrode plate 20, allowing the electrode plate 20 to expand and contract freely when heated, avoiding deformation and damage caused by excessive thermal stress, and reducing stress concentration and thermal deformation of the electrode plate 20.

[0060] Figure 8 for Figure 2 A schematic diagram showing the fit between the first support component and the shielding component of the radio frequency defrosting device. (Combined with...) Figure 2 and Figure 8 In some embodiments, to protect the electrode plate 20, a shielding member 40 is provided inside the housing 10 to form the radio frequency cavity 11 and the defrosting cavity 12. Since the electrode plate 20 is located inside the radio frequency cavity 11, it can be understood that the shielding member 40 is located between the electrode plate 20 and the defrosting cavity 12. By shielding the electrode plate 20 with the shielding member 40, external debris is prevented from falling into the radio frequency cavity 11 and damaging the electrode plate 20, thus ensuring the safety of the electrode plate 20 and improving its service life. The shielding member 40 can be made of glass.

[0061] In some embodiments, in order to ensure the stability of the first support member 30 during installation, one end of the first support member 30 abuts against the shielding member 40, and the other end abuts against the bottom wall of the radio frequency cavity 11. The shielding member 40 and the bottom wall of the radio frequency cavity 11 clamp the first support member 30, thereby restricting the first support member 30 in the axial direction. This allows the first support member 30 to be stably fixed in the designated position and will not be displaced or loosened due to external vibrations, impacts, or other factors, thus ensuring the stability of the entire structure.

[0062] Figure 9 for Figure 2 A schematic diagram showing the fit between the second support component and the electrode plate in the radio frequency defrosting device. (Combined with...) Figure 9 In some embodiments, in order to enable the electrode plate 20 to defrost the food, the radio frequency defrosting device further includes a power amplifier input 50. The power amplifier input 50 is electrically connected to the electrode plate 20.

[0063] In some embodiments, the radio frequency defrosting device further includes an amplifier board. The amplifier board is electrically connected to the amplifier input 50, and outputs an amplifier signal, which is sent to the electrode plate 20 through the supplier input 50. The electrode plate 20 radiates radio frequency energy to the food to rapidly defrost it.

[0064] In some embodiments, a limiting member is provided on the power amplifier inlet 50, and the electrode plate 20 is disposed on the limiting member. The limiting member supports the electrode plate 20, and the top end of the power amplifier inlet 50 passes through the electrode plate 20. A locking member is connected to the power amplifier inlet 50 to realize the connection between the electrode plate 20 and the power amplifier inlet 50. The locking member can be a bolt, and the nut of the bolt and the limiting member are respectively located on opposite sides of the electrode plate 20 to clamp the electrode plate 20 and ensure the connection stability between the power amplifier inlet 50 and the electrode plate 20.

[0065] In related technologies, screws are generally made of metal. When the electrode plate 20 is installed in the radio frequency cavity 11 using screws, the contact points between the screw and the electrode plate 20 and the housing 10 form hot spots. During equipment operation (such as under high power loads or in high-temperature environments), these hot spots can easily become bottlenecks in heat conduction, leading to excessively high local temperatures. Moreover, the difference in the coefficients of thermal expansion of different metal materials can easily cause stress concentration at the hot spots. Long-term operation may lead to deformation or cracking of the electrode plate 20. The hot spots hinder uniform heat conduction between the electrode plate 20 and the housing 10, reducing the overall heat dissipation performance. Especially in scenarios requiring efficient heat dissipation (such as high-power electronic devices), this may cause overheating failures.

[0066] In some embodiments, to avoid the formation of hot spots on the metal, the first support member 30 is made of a non-metallic material, making its thermal conductivity much lower than that of metal. In other words, no hot spots will form between the first support member 30 and the electrode plate 20, effectively blocking the transfer of heat from the hot spots on the electrode plate 20 to other components, preventing the local temperature of the electrode plate 20 from becoming too high. Moreover, the first support member 30 can absorb some of the heat from the electrode plate 20 and release it slowly, preventing the electrode plate 20 from overheating locally. It can also delay the diffusion of heat to the surrounding metal structure, reduce thermal stress, and prevent stress concentration at the notch 21 on the electrode plate 20, reducing the possibility of deformation or cracking of the electrode plate 20 and ensuring the safety of the electrode plate 20. At the same time, it will not hinder the uniform heat conduction between the electrode plate 20 and the housing 10, ensuring the overall heat dissipation performance.

[0067] In some embodiments, the first support member 30 may be made of PTFE (polytetrafluoroethylene), which allows the first support member 30 to maintain stable performance in the range of -200°C to +260°C, and the first support member 30 is resistant to high temperatures.

[0068] Combination Figure 9In some embodiments, to further ensure the stability of the electrode plate 20 installation, the radio frequency defrosting device further includes a second support member 60. The two ends of the second support member 60 are connected to the bottom wall of the radio frequency cavity 11 and the electrode plate 20, respectively. The second support member 60 provides support points for the electrode plate 20, preventing it from shaking or shifting under stress, ensuring the stability of the electrode plate 20 within the radio frequency cavity 11, thereby improving the operational stability of the device. The number of second support members 60 can be one or more.

[0069] In some embodiments, the two ends of the second support member 60 can be connected to the bottom wall of the radio frequency cavity 11 and the electrode plate 20 respectively by bolts, so that the second support member 60 can support the electrode plate 20.

[0070] In some embodiments, the second support member 60 may be made of metal to ground the electrode plate 20, thereby preventing abnormal voltage rise inside the device and protecting the device from damage.
