Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a radio frequency defrosting device and electrical equipment. Background Technology

For example, to meet users' needs for rapid defrosting of frozen food in appliances such as refrigerators and freezers, radio frequency defrosting devices are being installed within these appliances to quickly defrost the frozen food.

[0003] In the application of radio frequency defrosting devices, the sealing and shielding effect of the door is crucial. Poor sealing and shielding performance may not only lead to radio frequency energy leakage, affecting the health of operators and environmental safety, but also reduce defrosting efficiency and increase operating costs. Utility Model Content

This significantly improves the shielding performance of the door, greatly reducing the probability of radio frequency energy leakage and ensuring the health and safety of operators and the environment.

[0038] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0039] The following is for reference. Figures 1-7 This application describes a radio frequency defrosting apparatus and electrical device according to embodiments thereof.

[0040] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, the radio frequency defrosting device 10 includes a housing 100, a door 200, and a sealing assembly 300.

[0041] The housing 100 has a receiving cavity 110 and an opening 120 communicating with the receiving cavity 110.

[0042] A closed space is constructed through the enclosure 100, which has a receiving cavity 110 for placing items to be thawed. The opening 120 facilitates the placement and removal of items within the receiving cavity 110. The enclosure 100 can be made of metal, such as stainless steel, which has good strength, corrosion resistance, and shielding capabilities, and can withstand temperature changes and environmental influences during the radio frequency defrosting process.

[0043] The door 200 is installed on the housing 100 and can open and close the opening 120.

[0044] It should be noted that, Figure 1 This represents the closed state of the door 200 and opening 120. The door 200 can be installed on the housing 100 via hinges, sliding rails, or other connection methods to open and close the opening 120. The door 200 also uses metal or a composite structure of metal and other materials to ensure both strength and good shielding performance.

[0045] The sealing assembly 300 is disposed on the door 200 or the box 100 and is located between the door 200 and the box 100. The sealing assembly 300 includes a sealing element 310 and a conductive part 320 wrapped around the sealing element 310. The box 100 and the door 200 are connected through the conductive part 320.

[0046] The sealing element 310 primarily serves to fill the gap between the door 200 and the housing 100 to achieve a physical seal, preventing heat loss and the ingress of outside air. Its material can be selected from materials with good elasticity and aging resistance, such as sponge, silicone rubber, and EPDM rubber. The shape of the sealing element 310 can be strip-shaped, circular, etc. A common example is a continuous strip-shaped sealing element 310 around the edge of the door 200. When the door 200 is closed, the sealing element 310 is compressed and deformed, tightly fitting against the edge of the opening 120 of the housing 100, thereby achieving a seal.

[0047] The conductive part 320 is wrapped around the seal 310. When the door 200 is closed, the door 200 and the box 100 squeeze the sealing assembly 300 so that the conductive part 320 outside the seal 310 fits tightly with the box 100 and the door 200, reducing the resistance between the box 100 and the door 200, realizing the conduction between the two, and thus improving the electromagnetic shielding performance of the door 200.

[0048] In actual operation, when items need to be thawed, they are placed into the receiving cavity 110 of the box 100, and the door 200 is pushed to close the opening 120. At this time, the edge of the door 200 and the edge of the opening 120 of the box 100 press against the sealing element 310, causing elastic deformation and filling the gap between them to form a physical seal, preventing heat loss and the entry of outside air, and ensuring the temperature and environment stability inside the receiving cavity 110. At the same time, the conductive part 320 wrapped around the sealing element 310 is in close contact with the metal surfaces of the box 100 and the door 200, so that the box 100 and the door 200 are electrically connected through the conductive part 320. Due to the conductivity of the conductive part 320, the box 100 and the door 200 are electrically connected to form a continuous electromagnetic shielding structure, which confines the radio frequency energy within the containment cavity 110, reduces the probability of radio frequency energy leakage to the outside, thereby improving the shielding performance of the door 200, protecting the health of operators and the safety of the environment, and also enabling the radio frequency energy to act more effectively on the items to be thawed, improving the thawing efficiency and reducing operating costs caused by energy waste.

[0049] According to the radio frequency defrosting device 10 provided in this application embodiment, the sealing component 300 achieves the dual functions of physical sealing and electromagnetic shielding. The sealing component 310 effectively seals the gap between the door 200 and the opening 120 of the box 100, ensuring environmental stability within the receiving cavity 110, reducing heat loss, and improving defrosting efficiency. The conductive part 320 reduces the resistance between the box 100 and the door 200, enabling them to conduct and form a good electromagnetic shielding structure, significantly improving the shielding performance of the door 200, greatly reducing the probability of radio frequency energy radiation leakage, and ensuring the health and environmental safety of operators. Simultaneously, reduced energy leakage means more radio frequency energy can be used to defrost items, improving defrosting efficiency and reducing operating costs caused by energy waste.

[0050] According to some embodiments of this application, the sealing assembly 300 is disposed on the side of the door 200 near the housing 100.

[0051] By placing the sealing component 300 on the door 200, the edge of the opening 120 of the box 100 is made relatively flat, making it less likely for items to come into contact with or interfere with the sealing component 300 when taking them out or putting them in, thus improving ease of use and durability of the sealing component 300.

[0052] According to some embodiments of this application, the conductive part 320 may be a metallic conductive part 320.

[0053] The conductive part 320 can be made of a highly conductive metal material. For example, the material of the conductive part 320 may include copper, aluminum, stainless steel, etc. Metal materials have low resistivity, which can greatly reduce the contact resistance between the housing 100 and the door 200, allowing radio frequency energy to be effectively reflected and absorbed when it encounters the shielding structure, thereby reducing energy leakage. For example, when radio frequency energy attempts to leak from the inside of the receiving cavity 110, upon encountering the shielding layer formed by the metal conductive part 320, most of the energy will be reflected back into the receiving cavity 110, and only a very small portion of the energy can penetrate the shielding layer, thus significantly improving the shielding performance of the door 200.

[0054] Furthermore, the metal conductive part 320 has better stability, maintaining good conductivity during long-term use and is less affected by environmental factors (such as temperature and humidity). In addition, the metal material has strong mechanical strength and wear resistance, which can better protect the internal seal 310 and extend the service life of the sealing assembly 300.

[0055] Please see Figure 3 According to some embodiments of this application, the conductive part 320 may be attached to the surface of the seal 310.

[0056] The conductive part 320 is made of metal materials, such as copper foil or stainless steel sheet, and is tightly bonded to the surface of the sealing element 310 through a specific process. The bonding method can be achieved through adhesive bonding, pressing, or integral molding. This bonding method ensures that the conductive part 320 and the sealing element 310 are in close contact, guaranteeing stable conductivity, while not affecting the elasticity and sealing function of the sealing element 310. This ensures that the sealing element 310 can effectively fill gaps when the door 200 is closed, maintaining a good physical seal and improving defrosting efficiency. Furthermore, the tightly bonded structure forms a stable whole between the conductive part 320 and the sealing element 310, enhancing the durability of the sealing assembly 300, reducing problems such as component loosening and detachment, extending the service life of the radio frequency defrosting device 10, and reducing maintenance costs.

[0057] For example, when using the adhesive method, conductive adhesive is applied to the surface of the seal 310, and the metal conductive part 320 is adhered thereon; the pressing method uses a mold to tightly bond the metal conductive part 320 and the seal 310 under a certain pressure.

[0058] According to some embodiments of this application, the conductive part 320 may include a plurality of metal strips, which are staggered and attached to the surface of the seal 310.

[0059] The conductive part 320 is composed of multiple metal strips, which can be made of metal materials such as copper and aluminum, which have good conductivity and a certain degree of flexibility. The metal strips are elongated, and their dimensions can be flexibly adjusted according to actual needs. Multiple metal strips are attached to the surface of the sealing element 310 in a grid or cross pattern, so that the conductive part 320 maintains high conductivity. At the same time, because the metal strips interweave to form multiple movable connection points, when subjected to external pressure, tension, or deformation caused by the opening and closing of the door 200, the metal strips can move and deform relative to each other within a certain range without easily breaking or permanently deforming.

[0060] When the radio frequency defrosting device 10 is in operation, and the door 200 is frequently opened and closed or subjected to external forces, the sealing element 310 deforms accordingly. The interlaced metal strips attached to its surface, due to their unique mesh structure, can flexibly adapt to this deformation. The interlacing nodes between the metal strips allow them to bend and shift to a certain extent, dispersing external forces throughout the entire conductive part 320 structure and avoiding localized stress concentration. During the shielding of radio frequency energy, the interlaced metal strips reflect, absorb, and guide the radio frequency energy from multiple angles, forming a comprehensive shielding network. Even under long-term and frequent use, where the metal strips continuously undergo deformation, their excellent deformation capacity and stress dispersion characteristics prevent fatigue damage, maintaining consistently high conductivity and shielding performance, significantly extending the service life of the conductive part 320, and reducing equipment maintenance costs.

[0061] According to some embodiments of this application, the conductive part 320 may be a metal electroplated layer.

[0062] The metal electroplating layer is a uniform and dense metal film formed on the surface of the seal 310 through an electroplating process. The metal electroplating layer bonds tightly to the surface of the seal 310, conforming well to its shape. Whether the seal 310 is planar or has a complex curved structure, the electroplating layer forms a continuous conductive path. Furthermore, the thickness of the electroplating layer can be precisely controlled, typically between a few micrometers and tens of micrometers, ensuring good conductivity without adding excessive weight or volume. In addition to achieving conductivity, it may also improve the wear resistance and corrosion resistance of the seal 310 to some extent, extending its service life.

[0063] Common electroplated metals such as copper, silver, and nickel have low resistivity and can effectively conduct current, meeting the conductivity requirements of the radio frequency defrosting device 10.

[0064] According to some embodiments of this application, the conductive part 320 may include a fiber layer and a metal plating layer, the fiber layer being attached to the surface of the seal 310, and the metal plating layer being disposed outside the fiber layer.

[0065] The conductive part 320 adopts a structure similar to conductive cloth, consisting of a fiber layer and a metal plating layer. The fiber layer can be made of materials with certain flexibility and strength, such as polyester fiber or nylon fiber, allowing it to adhere to the surface of the sealing element 310. The metal plating layer can be applied to the outside of the fiber layer through processes such as chemical plating or electroplating; the metal material can be copper, nickel, silver, etc. This structure retains the flexibility of the fiber material while possessing the good conductivity of the metal, enabling the conductive part 320 to achieve electromagnetic shielding while adapting to the deformation and bending during the opening and closing of the door 200.

[0066] The bonding between the fiber layer and the surface of the seal 310 can be achieved in several ways. In some examples, adhesives are used for bonding, and adhesives with good conductivity and aging resistance are selected to ensure a strong bond and good conductivity between the fiber layer and the seal 310. In other examples, a hot-pressing process is used to tightly bond the fiber layer to the seal 310 under certain temperature and pressure conditions.

[0067] The metal plating of the conductive part 320, as the main conductive component, reflects and absorbs radio frequency energy, forming an electromagnetic shielding layer to reduce radio frequency energy leakage to the outside. The fiber layer supports the metal plating and enhances the overall flexibility of the conductive part 320, allowing it to better adapt to the opening and closing movements of the door 200 and the deformation of the seal 310. This ensures that the metal plating will not break due to deformation during long-term use, thus maintaining stable conductivity. In addition, the fiber layer also prevents the metal plating from directly rubbing against the seal 310, protecting the integrity of the metal plating.

[0068] According to some embodiments of this application, the conductive part 320 may be conductive ink.

[0069] Conductive ink is a functional ink composed of conductive fillers (such as silver powder, copper powder, carbon powder, etc.), binders (such as epoxy resin, polyurethane, etc.), solvents, and additives. In some examples, the conductive ink used as the conductive part 320 can be silver-based conductive ink, which has high conductivity and good chemical stability. The silver powder particles in the ink form a continuous conductive path, ensuring that the current can be effectively conducted, realizing the conduction between the housing 100 and the door 200. The conductive ink can be directly coated onto the surface of the sealing element 310 through printing processes (such as screen printing, spraying, inkjet printing, etc.) to form a conductive layer of uniform thickness.

[0070] Using conductive ink as the conductive part 320 offers high process flexibility. The coating thickness and shape of the conductive ink can be precisely controlled through the printing process, adapting to various complex sealing component structures 310, especially suitable for coating irregular surfaces. It is thin, lightweight, and does not significantly increase the weight of the door body 200. It also boasts strong durability; the cured conductive ink layer exhibits excellent wear resistance and chemical corrosion resistance, maintaining stable conductivity over a long period and reducing performance degradation caused by environmental factors, thus improving the overall performance of the device. Furthermore, conductive ink has lower material and processing costs and higher production efficiency, making it suitable for large-scale production.

[0071] Please see Figure 4 and Figure 5 It should be noted that, Figure 4 and Figure 5 The conductive part 320 is not shown. According to some embodiments of this application, the door body 200 may be provided with a limiting groove 211, and the sealing member 310 may include a main body 311 and an embedded part 312. The embedded part 312 is connected to the main body 311, the main body 311 is installed on the door body 200, and the embedded part 312 is embedded in the limiting groove 211.

[0072] The door body 200 is provided with a limiting groove 211, which can be a groove structure opened on the edge of the door body 200, and its shape and size are adapted to the embedded part 312 of the seal 310. The limiting groove 211 provides positioning and fixation for the embedded part 312 of the seal 310, ensuring the stability of the seal 310 installation.

[0073] The main body 311 of the seal 310 primarily seals the gap between the door 200 and the opening 120. Its material can be rubber or silicone with good elasticity and sealing properties, allowing it to fit tightly against the edge of the opening 120 of the box 100 when the door 200 is closed. The insert 312 can be integrally molded with the main body 311, or it can be connected by bonding or other methods. The shape of the insert 312 is designed to fit precisely into the limiting groove 211; for example, it can be a raised strip or block-like structure.

[0074] When the door 200 is closed, the main body 311 fits tightly against the edge of the opening 120 of the housing 100, sealing the receiving cavity 110, improving radio frequency defrosting efficiency, and preventing radio frequency energy leakage. The embedded part 312 is embedded in the limiting groove 211, making the connection between the seal 310 and the door 200 more stable, preventing easy displacement or detachment, improving the assembly stability of the seal 310, and thus enhancing the sealing performance between the housing 100 and the door 200, reducing the probability of radiation leakage. At the same time, due to the embedded assembly, the seal 310 can be quickly positioned and installed when it needs to be installed or replaced for maintenance, which is convenient and quick, improving production assembly and maintenance efficiency, and reducing production, use, and maintenance costs.

[0075] According to the embodiment of this application, the radio frequency defrosting device 10, through the structural design of the sealing element 310, uses the main body 311 to seal the gap between the door 200 and the opening 120 of the box 100. By setting the embedded part 312 and the limiting groove 211 to cooperate, the assembly stability of the sealing element 310 is improved, thereby improving the sealing effect between the box 100 and the door 200, reducing the probability of radiation leakage, and improving defrosting efficiency. Not only is the structure simple, but the embedded assembly can realize the quick positioning and installation of the sealing element 310, which is convenient for subsequent replacement and maintenance, improves maintenance efficiency, and reduces maintenance costs.

[0076] In some embodiments, two embedding portions 320 may be provided, with the two embedding portions 320 respectively disposed on both sides of the main body portion 310 near and away from the center of the door body 200, so that the seal 200 is generally T-shaped. The limiting groove 211 is provided with two corresponding to the embedding portions 320. By providing two embedding portions 320 arranged on both sides of the main body portion 310, the installation stability of the seal 300 is further guaranteed.

[0077] Please see Figure 4 and Figure 5 According to some embodiments of this application, the width of the main body 311 may have a decreasing trend in the direction away from the door body 200.

[0078] The design of the main body 311, whose width decreases in the direction away from the door 200, allows the main body 311 to fit better against the edge of the opening 120 of the cabinet 100 when the door 200 is closed. For example, the cross-section of the main body 311 can be trapezoidal, with the upper base close to the door 200 and the lower base away from the door 200, and the width of the upper base being greater than the width of the lower base; or the side of the main body 311 can be concave in an arc shape, which can also achieve the same effect of the width gradually decreasing in the direction away from the door 200.

[0079] In actual operation, the narrower portion of the main body 311 directly contacts the edge of the opening 120 of the housing 100. When the door 200 is closed, the gradually narrowing main body 311 deforms more significantly as it is compressed against the seal 310, thus filling the gap between the door 200 and the opening 120 of the housing 100 and increasing the sealing contact area. Simultaneously, this shape design ensures that the main body 311 experiences more even stress when compressed, further enhancing the sealing effect.

[0080] According to the embodiment of this application, the main body 311 can better adapt to the changes in the gap between the door 200 and the box 100 during the closing process of the door 200, so as to seal more tightly, further improve the sealing performance between the box 100 and the door 200, reduce the risk of radiation leakage, and at the same time give full play to the sealing performance of the sealing element 310 to ensure the stable operation of the radio frequency defrosting device 10.

[0081] Please see Figure 4 and Figure 5 According to some embodiments of this application, the surface of the main body 311 on the side away from the door body 200 may include an arcuate surface.

[0082] The curved surface can prevent stress concentration when the main body 311 comes into contact with the edge of the opening 120 of the box 100. At the same time, the curved surface can deform more flexibly when squeezed by the door 200 when it is closed, and better fit the surface of the edge of the opening 120 of the box 100.

[0083] In some examples, taking the cross-section of the main body 311 in the aforementioned embodiment as approximately trapezoidal and the bottom of the main body 311 being far from the door 200 as an example, the bottom edge of the main body 311 and the top corners at both ends of the bottom edge can be provided as arc surfaces, so that the surface of the main body 311 facing the box 100 is formed by splicing three arc surfaces; in other examples, the surface of the main body 311 on the side away from the door 200 can be a whole arc surface, and the two ends of the arc surface can be tangent to the side surface in the width direction of the main body 311.

[0084] The main body 311 with its curved surface gradually flattens as the door 200 closes, compressing the seal 310 and creating a larger contact area with the edge of the opening 120 of the housing 100, thus improving the sealing effect. In some examples, when there are minor unevennesses at the edge of the opening 120 of the housing 100, the curved surface can fill these uneven parts through its own deformation, achieving a tighter seal.

[0085] According to the embodiments of this application, an arc-shaped surface is provided on the main body 311, which enhances the fit between the main body 311 and the edge of the opening 120 of the box 100, effectively reduces the existence of gaps, greatly improves the sealing between the box 100 and the door 200, and further improves the safety and stability of the radio frequency defrosting device 10 during use.

[0086] Please see Figure 4 and Figure 5 According to some embodiments of this application, the main body 311 may be hollow.

[0087] The hollow structure of the main body 311 can take many forms. For example, the main body 311 can be a thin-walled structure with a single cavity inside, or it can be a structure with multiple hollow elongated cavities arranged side by side inside the main body 311, or it can be a honeycomb-shaped hollow structure inside the main body 311.

[0088] When the door 200 is closed, the hollow main body 311 is compressed by the edge of the opening 120 of the housing 100. Due to the hollow interior of the main body 311, it can deform more easily under pressure, filling the gap between the door 200 and the opening 120 of the housing 100 through its own elastic deformation. Taking a thin-walled structure with a single cavity inside the main body 311 as an example, when compressed, the cavity wall expands outwards, thereby increasing the contact area with the edge of the opening 120 of the housing 100; a honeycomb structure, on the other hand, allows each honeycomb unit to deform independently under pressure, better adapting to the shape of the gap.

[0089] According to the embodiments of this application, the main body 311 is hollow, which allows the sealing element 310 to have better elasticity and deformation capacity while ensuring a certain strength. Compared with a solid main body 311, it can more effectively seal the gap between the door 200 and the box 100, significantly improving the sealing performance between the box 100 and the door 200 and reducing the probability of radiation leakage. At the same time, the hollow structure can also reduce the amount of material used for the sealing element 310, reduce production costs, and to a certain extent reduce the weight of the sealing element 310, facilitating subsequent installation and replacement, improving maintenance efficiency, and reducing maintenance costs.

[0090] According to some embodiments of this application, the main body 311 may be provided with a vent hole communicating with its hollow portion.

[0091] The ventilation holes can be in various shapes such as round, square, and strip, and their number is not specifically limited; there can be one, two, three, or more.

[0092] The vent is directly connected to the hollow portion of the main body 311. During the closing process of the door 200, the seal 310 is compressed, and the air in the hollow portion is discharged through the vent. This allows the main body 311 to deform more quickly and smoothly, rapidly sealing the gap between the door 200 and the opening 120 of the housing 100. When the door 200 is opened, outside air can enter the hollow portion through the vent, helping the main body 311 to quickly return to its original shape, facilitating the next sealing operation.

[0093] According to the embodiments of this application, a vent hole communicating with the hollow part of the main body 311 is provided, which can effectively improve the air circulation of the seal 310 during the pressure and recovery process, avoid the problem of the main body 311 being obstructed or recovering slowly due to air accumulation, further improve the sealing efficiency and service life of the seal 310, ensure the sealing between the box 100 and the door 200 of the radio frequency defrosting device 10, reduce the risk of radiation leakage, and also make the use of the seal 310 more flexible and convenient.

[0094] Please see Figure 4 and Figure 5 According to some embodiments of this application, the surface of the main body 311 near the door 200 can be flush with the surface of the embedded part 312 near the door 200.

[0095] The surface of the main body 311 near the door 200 is flush with the surface of the embedded part 312 near the door 200, making the overall appearance of the seal 310 more regular when it is installed on the door 200, and ensuring a tighter and more uniform fit between the seal 310 and the door 200.

[0096] When the seal 310 is installed onto the door 200, because the corresponding surfaces of the main body 311 and the embedded part 312 are flush, the force between the seal 310 and the door 200 is more balanced during installation, reducing the occurrence of local stress concentration and helping to improve the stability of the seal 310 installation. Furthermore, this flush structural design allows the main body 311 and the embedded part 312 to deform collaboratively when the seal 310 is squeezed by the edge of the opening 120 of the housing 100 during the closing of the door 200, better filling the gap between the door 200 and the opening 120 of the housing 100, thereby further improving the sealing effect.

[0097] In some examples, the surface of the main body 311 near the door 200 is flush with the surface of the embedded part 312 near the door 200, and the width of the main body 311 tends to decrease in the direction away from the door 200, so that the overall cross-section of the seal 310 is similar to a P-shape.

[0098] According to the embodiment of this application, the sealing element 310 ensures a tight fit between the sealing element 310 and the door body 200, and enhances the stability and reliability of the overall installation of the sealing element 310.

[0099] Please see Figure 2 , Figure 4 and Figure 5 According to some embodiments of this application, the sealing member 310 may be arranged around the door body 200 and correspond to the periphery of the opening 120, and the embedded part 312 is provided on the side of the main body 311 facing the center of the door body 200.

[0100] The sealing element 310 is arranged around the door body 200 and corresponds to the periphery of the opening 120 of the housing 100, thereby sealing the entire opening 120. It can be understood that the shape of the sealing element 310 matches the shape of the door body 200 and the opening 120. This annular arrangement can fully cover the gap between the door body 200 and the opening 120 of the housing 100, effectively preventing radio frequency energy from leaking from the gap.

[0101] In some examples, the seal 310 can be a one-piece, closed annular frame.

[0102] In other examples, the seal 310 may include multiple segments connected end to end, which are connected by bonding or other means to form a closed annular frame. Specifically, taking the door 200 as a rectangle, the seal 310 may include four segments corresponding to the four sides of the door 200.

[0103] Due to the limited area of ​​the door 200, the embedded part 312 is located on the inner side, allowing the main body 311 to occupy a larger space. The larger main body 311 has a greater contact area with the edge of the opening 120 of the enclosure 100 when the door 200 is closed. After being compressed and deformed, it can more fully fill the gaps, greatly improving the sealing effect. For example, when the door 200 is closed, under pressure, the larger area of ​​the main body 311 can better fit the edge of the opening 120 of the enclosure 100, effectively blocking radio frequency energy while improving the sealing effect.

[0104] In some embodiments, the embedding portion 312 may also be disposed on the side of the main body portion 311 away from the center of the door body 200.

[0105] In some examples, when the edge of the opening 120 of the housing 100 has a relatively complex external structure (such as raised reinforcing ribs, heat dissipation structures, etc.), and these structures are far from the center of the door 200 and close to the edge of the door 200, placing the insert 312 on the side of the main body 311 away from the center of the door 200 can better utilize the space between the door 200 and the external structure of the edge of the opening 120 of the housing 100. This allows the insert 312 of the seal 310 to directly engage with the corresponding limiting groove 211 on the door 200, avoiding interference from the complex structure of the edge of the opening 120 of the housing 100 on the installation of the seal 310, thereby smoothly achieving the assembly of the seal 310.

[0106] In other examples, in scenarios where there are special requirements for the internal space of the door 200, such as when sensors, small control components, or other parts need to be installed inside the door 200, the embedded part 312 is placed on the side of the main body 311 away from the center of the door 200. This can reserve more space inside the door 200, avoid the embedded part 312 occupying the space near the center of the door 200, and facilitate the layout and installation of internal components.

[0107] According to some embodiments of this application, the door 200 or the box 100 includes a detachably mounted limiting plate 260, which forms the outer wall of the limiting groove 211.

[0108] It should be noted that when the limiting groove 211 is provided in the box body 100, the outer wall of the limiting groove 211 is the side wall near the door body 200, and the box body 100 includes a detachable limiting plate 260; when the limiting groove 211 is provided in the door body 200, the outer wall of the limiting groove 211 is the side wall near the box body 100, and the door body 200 includes a detachable limiting plate 260.

[0109] Please see Figure 4 and Figure 5 Taking the limiting groove 211 located on the door body 200 as an example, the door body 200 includes a detachably mounted limiting plate 260. The limiting plate 260 is located on the side of the door body 200 near the housing 100, so that the limiting plate 260 forms the outer wall of the limiting groove 211. The limiting plate 260 can be detachably connected to the main body of the door body 200 by means of snap-fit ​​connection or screw connection, etc., and the specific connection method is not limited.

[0110] In practice, before assembling the seal 300, the limiting plate 260 can be removed first. After the seal 300 is installed in the corresponding position on the door body 200, the limiting plate 260 is then installed. After assembly, the limiting plate 260 forms a limiting groove 211 with the main body of the door body 200 for limiting the sealing part, thus fixing the seal 300. This greatly reduces the assembly difficulty of the seal 300 and improves assembly efficiency and stability. When replacing or maintaining the seal 300, the limiting plate 260 can also be removed first, and then the seal 300 can be taken out. This facilitates the disassembly of the seal 300 and reduces the risk of irreversible damage to the seal 300.

[0111] Please see Figure 4 and Figure 5 According to some embodiments of this application, the door body 200 may be provided with an installation groove 212, the main body 311 may be installed in the installation groove 212, and the limiting groove 211 may communicate with the installation groove 212.

[0112] The mounting groove 212 provided on the door body 200 provides installation and positioning space for the main body 311 of the seal 310. The mounting groove 212 can be an annular groove surrounding the edge of the door body 200, and its shape and size are adapted to the main body 311 of the seal 310, so as to tightly wrap the main body 311. For example, the cross-section of the mounting groove 212 can be rectangular, fitting with the side of the main body 311 facing the door body 200. The main body 311 is installed in the mounting groove 212 and can be bonded with adhesive to further tighten the fit between the main body 311 and the inner wall of the mounting groove 212.

[0113] The limiting groove 211 communicates with the mounting groove 212, allowing the insert 312 to smoothly extend from the mounting groove 212 into the limiting groove 211, thus achieving a fit with the limiting groove 211. The limiting groove 211 can be a recessed structure extending from the side wall of the mounting groove 212, with its depth and width matching that of the insert 312. When the seal 310 is installed, as the main body 311 is placed in the mounting groove 212, the insert 312 can slide into the limiting groove 211 along the communicating channel, completing the entire installation process of the seal 310. The installation is simple and highly stable.

[0114] When the door 200 is closed, the main body 311 installed in the mounting groove 212 is squeezed by the edge of the opening 120 of the housing 100. Due to the limiting effect of the mounting groove 212, the main body 311 will not shift, thus stably performing its sealing function. At the same time, the embedded part 312 is embedded in the limiting groove 211, further enhancing the assembly stability of the seal 310. The two work together to make the connection between the seal 310 and the door 200 more secure, effectively improving the sealing performance between the housing 100 and the door 200 and greatly reducing the possibility of radio frequency energy leakage. In addition, the design of the mounting groove 212 and the connected limiting groove 211 facilitates the installation and removal of the seal 310. When the seal 310 needs to be replaced, the operator can quickly remove it from the mounting groove 212 and the limiting groove 211, significantly improving maintenance efficiency and reducing maintenance costs.

[0115] Please see Figure 2 and Figure 6 According to some embodiments of this application, the door 200 includes a main body 210 and a panel 220. The sealing component 300 is disposed on the side of the main body 210 facing the housing 100. The main body 210 is integrally formed of metal material. The panel 220 is installed on the side of the main body 210 away from the housing 100.

[0116] The door 200 consists of a main board 210 and a panel 220. The main board 210 is the main supporting structure of the door 200 and the core component for achieving the shielding function. The main board 210 is integrally molded from metal, such as stainless steel or aluminum alloy, which have good conductivity and mechanical strength. This integral molding avoids gaps and weak points caused by splicing and welding processes, not only improving the overall structural strength of the main board 210 and making it less prone to deformation and damage during frequent opening and closing, but also ensuring good shielding performance. Together with the enclosure 100, it forms a closed shielded space, effectively blocking radio frequency energy leakage, and simplifying the assembly process and improving production efficiency. Simultaneously, the integral molding process allows the surface of the main board 210 facing the enclosure 100 to maintain a high degree of flatness. Because of the flat surface of the main board 210, the sealing component 300 is located on the side of the main board 210 facing the enclosure 100, ensuring a tight fit and achieving good sealing and conductivity.

[0117] Panel 220 is installed on the side of main body 210 opposite to enclosure 100. Panel 220 can be made of plastic, metal, or composite materials. Panel 220 provides an aesthetically pleasing appearance for door 200 and can be fitted with components such as operation buttons and display screens according to actual needs. Panel 220 and main body 210 can be fixedly installed by means of screw connection, snap-fit ​​connection, or adhesive.

[0118] The sealing assembly 300 is directly mounted on the side of the main board 210 facing the enclosure 100. The sealing assembly 300 is tightly fitted to the surface of the main board 210, and the conductive part 320 forms an electrical connection with the main board 210. When the door 200 is closed, the conductive part 320 of the sealing assembly 300 contacts the metal part of the enclosure 100, realizing the conduction between the enclosure 100 and the door 200, forming a complete electromagnetic shielding circuit. The panel 220 covers the surface of the main board 210 facing away from the enclosure 100 and is firmly connected to the main board 210, together forming the door 200 structure, giving the door 200 both functionality and a good appearance.

[0119] In some examples, the door 200 may also include an upper decorative panel and a lower decorative panel. The upper decorative panel can wrap around the upper ends of the main body 210 and the panel 220, and is fixedly connected to the main body 210 with screws, serving both a decorative function and limiting and fixing the upper end of the panel 220. The lower decorative panel can wrap around the lower ends of the main body 210 and the panel 220, and is fixedly connected to the lower end of the main body 210 with screws, serving both a decorative function and limiting and fixing the lower end of the panel 220. The upper and lower decorative panels close the gap between the upper and lower ends of the main body 210 and the panel 220 while simultaneously limiting and fixing the panel 220.

[0120] Compared to related technologies that use a plastic main body 210 with an additional thin metal plate, the one-piece metal main body 210 in this solution eliminates the need for complex concave-convex structures to enhance strength, simplifying the structural design and reducing assembly steps. For example, when adding a metal plate to the plastic main body 210, the plastic plate needs to be processed to fix the metal plate, and the connection gap between the two also needs to be addressed. However, the one-piece metal main body 210 in this solution directly eliminates these cumbersome steps, significantly reducing assembly difficulty and improving production efficiency. It also avoids the problem of reduced sealing performance caused by uneven structure, further ensuring the sealing and reliability of the radio frequency defrosting device 10.
