[0002] As users' demands for electrical appliances increase, the functionality of these appliances is also constantly expanding. 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 related technologies, the lack of a locking mechanism between the door and the housing of the radio frequency defrosting device makes it impossible to guarantee the airtightness between the door and the housing, which leads to leakage of radio frequency energy inside the housing. This can cause harm to the human body and affect the radio frequency defrosting device's judgment of defrosting time, thus affecting the defrosting effect. Utility Model Content

[0058] 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.

[0059] The following is for reference. Figures 1-19 This application describes a radio frequency defrosting apparatus and electrical device according to embodiments thereof.

[0060] Please see Figure 1 and Figure 2 According to some embodiments of this application, the radio frequency defrosting device 10 includes a housing 100, a door 200, a limiting member 400, and a locking member 500.

[0061] The housing 100 has a receiving cavity 110 and an opening 120 communicating with the receiving cavity 110.

[0062] 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.

[0063] The door 200 is installed on the housing 100 and can open and close the opening 120.

[0064] The door 200 can be installed on the housing 100 via hinges, sliding rails, or other connection methods to enable the opening and closing of 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.

[0065] Limiting component 400 is installed on housing 100.

[0066] The limiting member 400 is fixedly installed on the housing 100 near the edge of the opening 120. The structural shape of the limiting member 400 can be designed according to the shape of the hook portion 510. In one example, the limiting member 400 can be a block structure, and a groove or protrusion is provided at the position that mates with the hook portion 510. For example, the limiting member 400 has a protruding columnar structure, the shape and size of which match the hook-shaped opening of the hook portion 510, providing a basic structure for locking the hook portion 510.

[0067] The locking element 500 is installed on the door body 200, and the locking element 500 has a locked position and an unlocked position, and the locking element 500 can switch between the locked position and the unlocked position.

[0068] Please refer to further information. Figure 3 , Figure 1 The locking element 500 is in the locked position. Figure 3 The central locking element 500 is in the unlocked position.

[0069] The locking element 500 is installed on the door body 200 and can be connected to the door body 200 by bolt fixing or embedding. The locking element 500 has two working states: a locked position and an unlocked position, which can be switched between the two positions by manual operation, electric drive, or pneumatic drive. For example, the locking element 500 can be designed as a rotary structure, in which the operator rotates the locking element 500 by rotating a handle; it can also adopt an electric push rod structure, in which the position switching of the locking element 500 is achieved by the extension and retraction of the push rod driven by a motor.

[0070] Please refer to further information. Figure 4The locking member 500 is provided with a hook portion 510. When the locking member 500 is in the locked position, the hook portion 510 locks with the limiting member 400 to close the opening 120 of the door body 200. When the locking member 500 is in the unlocked position, the hook portion 510 unlocks with the limiting member 400 to open the opening 120 of the door body 200.

[0071] The hook portion 510 is located at the end of the locking member 500 near the limiting member 400. The hook portion 510 can be hook-shaped, and its size and angle can be designed according to the structure of the limiting member 400 to ensure a tight fit with the limiting member 400 when locked. When the door 200 needs to be closed, push the door 200 to cover the opening 120, and operate the locking member 500 to move to the locked position. As the locking member 500 moves, the hook portion 510 gradually approaches the limiting member 400. When the locking member 500 reaches the locked position, the hook portion 510 precisely hooks onto the limiting member 400, and the two interlock to form a strong locking structure, firmly fixing the door 200 to the housing 100. At this time, the sealing member 300 between the door 200 and the housing 100 is fully compressed, achieving a good sealing effect and effectively preventing radio frequency energy leakage. When it is necessary to open the door 200, the locking element 500 is moved to the unlocked position, and the hook part 510 gradually disengages from the limiting element 400, releasing the locking state between the two. At this time, the door 200 is no longer constrained by the locking element 500 and can be easily pulled open, realizing the opening 120.

[0072] According to the radio frequency defrosting device 10 provided in the embodiments of this application, the locking engagement between the hook portion 510 and the limiting member 400 can provide a strong and stable locking force, ensuring the sealing and stability of the door 200 when closed, significantly improving defrosting efficiency, reducing the probability of radiation leakage, and reducing the cost of using the equipment. When it is necessary to open the door 200, it is only necessary to control the locking member 500 to move to the unlock position, and the hook portion 510 will quickly unlock with the limiting member 400, making it easy and free to open the door 200. The locking and unlocking operation of the door 200 is simple and convenient, significantly improving the convenience of using the equipment and the user experience.

[0073] Please see Figure 4 and Figure 5 According to some embodiments of this application, when the locking member 500 is in the locked position, the limiting member 400 can be located between the hook portion 510 and the door body 200.

[0074] The hook portion 510 can be hook-shaped, with its opening engaging with the limiting member 400. The limiting member 400 can be configured as a block or column structure, installed on the housing 100 near the opening 120. When the door 200 is closed and the locking member 500 is switched to the locked position, the hook portion 510 moves at a certain angle and along a certain trajectory until it firmly hooks the limiting member 400. At this point, the limiting member 400 is tightly clamped between the hook portion 510 and the door 200. This locking structure allows the locking force applied by the locking member 500 to act directly on the limiting member 400 through the hook portion 510 and further transmitted to the housing 100, forming a stable force-bearing system.

[0075] In practical use, this structure effectively prevents loosening caused by external impacts or equipment vibrations. For example, when the radio frequency defrosting device 10 is running, internal vibrations may cause a certain displacement tendency in the door 200. However, because the limiting member 400 is locked between the hook portion 510 and the door 200, the hook portion 510 can tightly hold the limiting member 400, limiting the displacement of the door 200 and ensuring that the door 200 and the housing 100 are always tightly fitted. Simultaneously, this structure also allows the sealing member 300 to be subjected to uniform and continuous compression, ensuring the sealing effect between the door 200 and the housing 100 and effectively preventing radio frequency radiation leakage.

[0076] Please see Figure 3 , Figure 4 and Figure 5 According to some embodiments of this application, the locking member 500 may further include a rotating part 520 connected to the hook part 510. The rotating part 520 may be rotatably connected to the door body 200 so that the rotating part 520 may drive the hook part 510 to lock or unlock the limiting member 400.

[0077] The locking component 500 may include a hook portion 510 and a rotating portion 520, which cooperate to achieve precise locking and unlocking functions. The rotating portion 520 can be rotatably connected to the door body 200 by means of a pin or a pivot. Specifically, a fixing pin is provided at a corresponding position on the door body 200, and the rotating portion 520 is provided with a shaft hole. The shaft hole is fitted over the fixing pin to form a rotatable connection, ensuring that the rotating portion 520 can rotate flexibly and stably around the shaft.

[0078] The rotating part 520 and the hook part 510 can be firmly connected by welding, integral molding, or other methods. When the rotating part 520 rotates, the hook part 510 moves synchronously. When the door 200 needs to be closed, the rotating part 520 rotates around the connecting shaft. During the rotation, the hook part 510 gradually approaches the limiting member 400 installed on the housing 100 until it rotates to a specific angle, i.e., the locking position. At this point, the hook part 510 precisely hooks the limiting member 400, locking the door 200 and the housing 100. The door 200 is tightly fitted against the housing 100, and the sealing member 300 is fully compressed, ensuring a good sealing effect.

[0079] When it is necessary to open the door 200, the rotating part 520 can be rotated in the opposite direction. The rotating part 520 drives the hook part 510 to rotate in the opposite direction, causing the hook part 510 to disengage from the limiting member 400 and release the locked state. With the hook part 510 and the limiting member 400 unlocked, the door 200 is no longer constrained by the locking force and can be easily opened.

[0080] The rotating connection ensures stable and reliable locking and unlocking between the hook part 510 and the limiting member 400, avoiding problems such as loose locking or difficulty in unlocking due to improper operation. Furthermore, this compact design makes efficient use of the space in the door 200, optimizing the equipment structure and improving its ease of use and reliability while ensuring the overall sealing and stability of the radio frequency defrosting device 10.

[0081] Please see Figure 4 and Figure 5 According to some embodiments of this application, in the depth direction of the box 100, the hook portion 510 has a first surface 511 on the side near the door 200. When the locking member 500 is in the locked position, the first surface 511 can cooperate with the limiting member 400 to limit the position.

[0082] The way the first surface 511 and the limiting member 400 are matched can be designed according to actual needs. For example, if the limiting member 400 is a columnar structure, the first surface 511 can be designed as an arc-shaped surface that fits the outer surface of the columnar structure. When the two are in contact, they can form a surface contact, increase the contact area, and make the limiting effect more stable. If the limiting member 400 is a block structure, the first surface 511 can be designed as a plane, which closely abuts against the corresponding plane of the limiting member 400 to achieve reliable limiting.

[0083] The first surface 511 presses firmly against the limiting member 400, restricting the relative displacement between the hook portion 510 and the limiting member 400, thereby preventing the door body 200 from loosening. This limiting fit ensures that the door body 200 and the housing 100 always remain tightly fitted, so that the sealing member 300 is continuously and stably compressed, maintaining a good sealing state and effectively preventing the leakage of radio frequency radiation.

[0084] Please see Figure 4 and Figure 5 According to some embodiments of this application, the first surface 511 can be an arc shape with its axis parallel to the rotation axis of the rotating part 520.

[0085] When the locking member 500 is in the locked position, the arc-shaped first surface 511 can form good surface contact with the limiting member 400. If the limiting member 400 is a columnar structure, the arc-shaped first surface 511 can wrap around the side of the limiting member 400. The contact area between the two is larger than the line contact between a plane and a columnar structure, thus generating greater friction and limiting force. This makes it difficult for the limiting member 400 to come out of the arc-shaped first surface 511 of the hook portion 510 during the operation of the radio frequency defrosting device 10, even if it is affected by vibration, external impact, etc., effectively preventing the door 200 from loosening, maintaining a tight fit between the door 200 and the box 100, ensuring that the sealing member 300 continues to perform its sealing function, and greatly reducing the risk of radio frequency radiation leakage.

[0086] Meanwhile, since the axis of the arc-shaped first surface 511 is parallel to the rotation axis of the rotating part 520, when the rotating part 520 drives the hook part 510 to lock or unlock, the rotation of the hook part 510 around the rotation axis allows the arc-shaped first surface 511 to smoothly approach or move away from the limiting member 400. This smooth movement trajectory not only makes the operation process smoother and less strenuous, but also reduces wear between the hook part 510 and the limiting member 400, extending the service life of the locking member 500 and the limiting member 400. In addition, the arc-shaped structure design also makes the appearance of the hook part 510 more streamlined, improving the aesthetics and coordination of the overall structure of the radio frequency defrosting device 10 while meeting functional requirements, further enhancing the practicality and reliability of the equipment.

[0087] Please see Figures 4 to 9 It should be noted that, Figures 6 to 9 The diagram sequentially illustrates the positional changes and engagement between the locking member 500 and the limiting member 400 as the door 200 moves from the open position toward the housing 100. According to some embodiments of this application, in the depth direction of the housing 100, the hook portion 510 may have a second surface 512 on the side away from the door 200, and the second surface 512 may slide and engage with the limiting member 400.

[0088] The shape of the second surface 512 needs to take into account both the fit with the limiting member 400 and the smoothness of movement. For example, the second surface 512 can be a sloping surface design that is set at an angle to the depth direction of the box 100, or it can be designed as an arc surface or a spherical structure.

[0089] As the door 200 moves closer to the housing 100, the latch 510 moves along with the door 200, at which point the second surface 512 gradually comes into contact with the limiting member 400. As the door 200 continues to approach the housing 100, the reaction force of the limiting member 400 is transmitted to the rotating part 520 through the second surface 512, causing relative sliding between the second surface 512 and the limiting member 400. This allows the latch 510 to first avoid the limiting member 400, facilitating the subsequent locking action of the latch 510.

[0090] According to some embodiments of this application, the limiting member 400 can be rotatably connected to the box 100, and during the process of the door 200 moving closer to the box 100, the second surface 512 can be rolled in cooperation with the limiting member 400.

[0091] The limiting member 400 and the housing 100 are rotatably connected by bearings, pins and other means to ensure that the limiting member 400 can rotate flexibly, while having sufficient structural strength to withstand the force applied by the hook part 510.

[0092] It should be noted that the rotation axis of the limiting member 400 can be arranged parallel to the rotation axis of the rotating part 520, so as to reduce the frictional resistance between the hook part 510 and the limiting member 400 during rolling engagement and improve the smoothness of the engagement. The limiting member 400 can be a cylindrical roller.

[0093] Because the limiting member 400 is rotatable, a rolling contact is formed between the two. Compared with sliding friction, this rolling contact can significantly reduce the friction between the hook part 510 and the limiting member 400, making the closing process of the door 200 smoother and less strenuous. The operator does not need to apply excessive force to easily push the door 200 to complete the closing action, effectively improving the convenience of the equipment, while also reducing frictional wear between the second side 512 and the limiting member 400, and improving the durability of the device.

[0094] When the door 200 is closed, rotating the rotating part 520 causes the hook part 510 to enter the locked position. During this process, the rotating part 520 can rotate under the action of external force or under its own weight or other forces. At this time, the first surface 511 of the hook part 510 is in close contact with the limiting member 400, achieving a secure lock on the door 200. When it is necessary to open the door 200, rotating the rotating part 520 is rotated in the opposite direction, and the hook part 510 moves from the locked position to the unlocked position. During the process of the hook part 510 disengaging from the limiting member 400, the first surface 511 forms a rolling contact with the rotating limiting member 400. Since the first surface 511 is an arc shape with its axis parallel to the rotation axis of the rotating part 520, it can achieve good rolling contact with the limiting member 400, thereby significantly reducing the friction when the two separate, reducing wear between the first surface 511 and the limiting member 400, extending the service life of the locking member 500 and the limiting member 400, and reducing the maintenance cost of the equipment.

[0095] In addition, the rolling mechanism can absorb impact during the closing and opening of the door 200, reducing vibration and noise caused by collisions, making the radio frequency defrosting device 10 operate more smoothly and quietly. This structural design utilizes the motion relationship between components, optimizing the overall structure and improving the overall performance and user experience of the device while ensuring the sealing performance and locking reliability of the door 200.

[0096] Please see Figure 4 and Figure 5 According to some embodiments of this application, the second surface 512 can be arc-shaped, and the projection of the axis of the second surface 512 and the axis of the limiting member 400 in the depth direction of the housing 100 can be staggered.

[0097] First, it should be noted that the door 200 in this embodiment can move along the depth direction of the box 100 to open and close the opening 120.

[0098] The arc-shaped structure of the second surface 512 can effectively reduce the friction when it rolls with the limiting member 400. The radius and curvature of the arc are designed according to the size of the limiting member 400 and the fitting requirements between the hook part 510 and the limiting member 400.

[0099] The axis of the second surface 512 and the axis of the limiting member 400 are offset in the projection of their respective axes along the depth direction of the housing 100. The limiting member 400 can be located on the side of the housing 100 in the height direction or on the side of the housing 100 in the width direction. Specifically, when the limiting member 400 is located on the side of the housing 100 in the height direction, the axis of rotation of the rotating part 520 extends along the height direction of the housing 100, and the axis of the second surface 512 and the axis of the limiting member 400 are offset in the width direction of the housing 100; when the limiting member 400 is located on the side of the housing 100 in the width direction, the axis of rotation of the rotating part 520 extends along the width direction of the housing 100, and the axis of the second surface 512 and the axis of the limiting member 400 are offset in the height direction of the housing 100. As the door 200 moves closer to the housing 100, the hook portion 510 moves along with the door 200, and the second surface 512 begins to contact the limiting member 400. Due to the arc-shaped design of the second surface 512 and its projected misalignment with the axis of the limiting member 400, a unique rolling starting point and rolling trajectory are formed at the moment of contact. This misalignment causes the contact point between the second surface 512 and the limiting member 400 to continuously change during the rolling process, avoiding excessive local wear and effectively extending the service life of the component.

[0100] The misalignment design allows the hook portion 510 to generate a component force that facilitates the closing of the door 200 when it rolls in engagement with the limiting member 400. This component force can push the hook portion 510 towards one side of the limiting member 400, thereby driving the rotating part 520 to rotate. As the door 200 closes, the hook portion 510 rotates to a misaligned position with the limiting member 400, making it easier for the operator to push the door 200 to the closed position, reducing the force required to close the door and improving operational convenience.

[0101] Please see Figure 4 as well as Figures 6 to 9 According to some embodiments of this application, the locking member 500 further includes a connecting portion 530, a hook portion 510 and a rotating portion 520 are spaced apart in the depth direction of the housing 100, and one end of the rotating portion 520 and the hook portion 510 are connected by the connecting portion 530 so that the hook portion 510, the connecting portion 530 and the rotating portion 520 define a snap-fit ​​groove 540 for accommodating the limiting member 400; when the locking member 500 is in the locked position, the limiting member 400 is located in the snap-fit ​​groove 540.

[0102] The hook portion 510 and the rotating portion 520 are spaced apart in the depth direction of the housing 100. The distance between the hook portion 510 and the rotating portion 520 is not less than the diameter of the limiting member 400, so that the limiting member 400 can enter the locking groove 540.

[0103] The connecting portion 530 is connected to the same end of the hook portion 510 and the rotating portion 520, so that the connecting portion 530, the hook portion 510, and the rotating portion 520 define a snap-fit ​​groove 540 with an opening 120 on one side. Specifically, the connecting portion 530 forms the bottom wall of the snap-fit ​​groove 540 in the depth direction, and the hook portion 510 and the rotating portion 520 form the two side walls of the snap-fit ​​groove 540. It can be understood that the first surface 511 of the hook portion 510 serves as one of the side walls of the snap-fit ​​groove 540. The connecting portion 530 can be used by welding, integral molding, or other methods to firmly connect one end of the rotating portion 520 and the hook portion 510, thereby ensuring the structural stability of the three components.

[0104] The locking groove 540 provides a specific movement space for the limiting member 400. When the door 200 moves from the open position toward the box 100, the second surface 512 of the hook part 510 first contacts and rolls with the limiting member 400. As the door 200 continues to move closer, the second surface 512 gradually separates from the limiting member 400. After the second surface 512 completely separates from the limiting member 400, the limiting member 400 can just enter the locking groove 540 to achieve locking and limiting.

[0105] The design of the locking groove 540 serves to position and guide the limiting member 400. During the closing process of the door 200, when the limiting member 400 enters the locking groove 540, the bottom of the groove 540, i.e., the connecting part 530, can limit the limiting member 400, thereby limiting the locking member 500 itself and preventing excessive movement and separation from the limiting member 400. This ensures the accuracy of its movement trajectory, allowing the hook part 510 to more precisely lock with the limiting member 400. On the other hand, the locking groove 540 also enhances the stability of the door 200 when closed. When the limiting member 400 is located within the locking groove 540, it forms a relatively stable structural system with the hook part 510, the connecting part 530, and the rotating part 520, effectively resisting external vibrations and impacts and preventing the door 200 from loosening when closed.

[0106] Please see Figures 3 to 9 According to some embodiments of this application, the locking member 500 may be provided on the side of the door 200 in the width direction of the box 100, and the rotation axis of the rotating part 520 may extend along the width direction of the box 100; the locking member 500 may be provided on the side of the door 200 in the height direction of the box 100, and the rotation axis of the rotating part 520 may extend along the height direction of the box 100.

[0107] In some examples, the limiting member 400 can be provided on the side of the box 100 in the height direction. In this case, the locking member 500 can be provided on the side of the door 200 in the height direction of the box 100. The rotation axis of the rotating part 520 extends along the height direction of the box 100. When the locking member 500 rotates, the hook part 510 moves in the width direction of the box 100.

[0108] In other examples, the limiting member 400 may also be provided on the side of the box 100 in the width direction. In this case, the locking member 500 may be provided on the side of the door 200 in the width direction of the box 100. When the rotation axis of the rotating part 520 extends along the width direction of the box 100, when the locking member 500 rotates, the hook part 510 moves in the height direction of the box 100.

[0109] Taking the locking element 500 located on the side of the door 200 along the width of the housing 100 as an example, the rotation axis of the rotating part 520 is set along the width of the housing 100. When the operator operates, the direction of force applied by their hand is more aligned with the opening and closing direction of the door 200, conforming to ergonomic principles. For example, when the user operates from the front of the radiofrequency defrosting device 10, the vertical pulling motion of the locking element 500 is natural and smooth, requiring no complex twisting or posture adjustments, reducing operational difficulty and improving ease of use. The same principle applies to the locking element 500 located on the side of the door 200 along the height of the housing 100.

[0110] When the rotation axis of the rotating part 520 extends along the width direction of the housing 100, the hook part 510 is displaced relative to the housing 100 in the height direction of the housing 100. It is understood that when the door 200 moves along the depth direction of the housing 100 to open and close the opening 120, to facilitate unlocking of the door 200, the hook part 510 and the limiting member 400 need to be offset in the height direction of the housing 100 when the locking member 500 is in the unlocked position. At this time, when the hook part 510 is unlocked, there are two installation methods: upward rotation and downward rotation. For some examples, please refer to... Figure 5 The connecting portion 530 is located below the limiting member 400, the slot of the locking groove 540 faces upward, and the locking hook portion 510 rotates downward to unlock from the limiting member 400 when unlocked; in other examples, the connecting portion 530 is located above the limiting member 400, as can be seen in the following examples. Figure 5 After rotating 180°, the slot of the locking groove 540 faces downwards, and the locking hook 510 rotates upwards to unlock with the limiting member 400 when unlocking.

[0111] Taking the example where the connecting part 530 is located below the limiting member 400, the height of the hook part 510 in the locked position is higher than the height of the hook part 510 in the unlocked position. Therefore, when the locking member 500 is in the unlocked position, the hook part 510 is located below the limiting member 400.

[0112] During the closing process of the door 200, the action of the locking component 500 is divided into two stages:

[0113] First section: When the door 200 moves closer to the housing 100, the latch 510 moves along with the door 200. At this time, the second surface 512 of the latch 510 on the side away from the door 200 first contacts and abuts against the limiting member 400 rotatably connected to the housing 100. Since the latch 510 and the limiting member 400 are facing each other in the initial state, and the latch 510 is located on the side of the limiting member 400 closer to the door 200, as the door 200 moves forward, the limiting member 400 applies a force to the latch 510, pushing the latch 510 downward and towards the unlocked position of the locking member 500. This causes the latch 510 and the limiting member 400 to be misaligned, and their relative positions change. During this process, the second side 512 and the limiting member 400 are in a rolling fit. This rolling fit can reduce the friction between the two, making the downward movement of the hook part 510 smoother. The operator does not need to apply too much force to push the door 200 closer to the box 100.

[0114] Second section: As the door 200 continues to approach the housing 100, until the second surface 512 separates from the limiting member 400, the locking member 500 moves to the position corresponding to the locking groove 540 and the limiting member 400. The rotating part 520 drives the hook part 510 to rotate upward, that is, to move towards the locking position of the locking member 500. During the upward movement of the hook part 510, the limiting member 400 gradually enters the locking groove 540 defined by the hook part 510, the connecting part 530, and the rotating part 520. When the hook part 510 moves to the locking position, the first surface 511 of the hook part 510 on the side near the door 200 tightly abuts against the limiting member 400, achieving a secure lock on the door 200. During this process, the hook part 510 rotates upward to the locked position. The component of its own weight along the contact direction between the hook part 510 and the limiting member 400 will cause the hook part 510 to tend to press against the limiting member 400, increasing the pressure between the hook part 510 and the limiting member 400, thereby increasing the friction, making the locking of the door 200 more stable and effectively preventing the door 200 from loosening due to external factors.

[0115] The unlocking process is the reverse of the closing process. The operator rotates the rotating part 520 in the opposite direction, and the hook part 510 moves downward from the locked position, that is, towards the unlocked position. During the downward movement of the hook part 510, the abutment between the first surface 511 and the limiting member 400 is gradually released, and the limiting member 400 is disengaged from the locking groove 540, thereby unlocking the door 200 and allowing the door 200 to be opened.

[0116] According to some embodiments of this application, an elastic member 550 may be connected between the rotating part 520 and the door body 200, and the elastic member 550 may apply a restoring force to the locking member 500 in a direction away from the box body 100.

[0117] It should be noted that because the latch 510 will contact the limiter 400 first during the closing process of the door 200, the user may mistakenly believe that the door 200 has been closed properly after receiving feedback that the limiter 400 has contacted the latch 510 when closing the door, resulting in the door 200 not being closed tightly.

[0118] Please see Figure 8 By providing an elastic member 550 between the rotating part 520 and the door body 200, and by applying a restoring force away from the housing 100 to the locking member 500, after the locking member 500 is unlocked from the limiting member 400, the locking member 500 can rotate away from the housing 100 under the action of the elastic member 550, that is, the locking member 500 moves outward from the door body 200, so that at least a portion of the locking member 500 protrudes from the outer surface of the door body 200 and remains there. Exemplarily, the locking member 500 can be held in place by the action of the elastic member 550. Figure 8 The position shown in the figure serves as a visual reminder to the user when the door 200 is in the open state or when the locking member 500 is not locked in cooperation with the limiting member 400, conveying the visual information that the door 200 is not closed properly.

[0119] In the final stage of closing, the user can manually press to drive the locking element 500 to overcome the elastic force of the elastic element 550, causing the locking element 500 to lock into place with the limiting element 400. After the locking element 500 retracts to the side of the door 200, and the user confirms that the locking element 500 is not protruding from the outer surface of the door 200, the door 200 is fully closed. This reduces the risk of the door 200 not closing completely due to user error.

[0120] The specific form of the elastic element 550 is not limited. In some examples, such as... Figure 8 As shown, the elastic element 550 can be a torsion spring sleeved on the shaft of the rotating part 520, with one end of the torsion spring connected to the rotating part 520 and the other end connected to the side of the door body 200. In other examples, the elastic element 550 can also be a spring connected between the rotating part 520 and the door body 200.

[0121] Please see Figure 4 and Figure 5 According to some embodiments of this application, the radio frequency defrosting device 10 may further include a handle 600, which may be fixedly connected to the connecting part 530. The handle 600 may drive the rotating part 520 under the drive of an external force, so as to unlock the hook part 510 from the limiting member 400.

[0122] The handle 600 can be made of high-strength engineering plastics or aluminum alloy, and is securely connected to the connecting part 530 through bolting, riveting, welding, or other processes to ensure structural stability during frequent operation. When the user needs to open the door 200, they grasp the handle 600 and apply an outward pulling force. This force is transmitted through the connecting part 530 to the rotating part 520, driving the hook part 510 to rotate around the rotation axis. This causes the first surface 511 of the hook part 510 to disengage from the limiting part 400, completing the unlocking action. This operation conforms to ergonomic grip habits, greatly reducing the force and difficulty of operation.

[0123] According to some embodiments of this application, the locking member 500 may be provided on the side of the door body 200 in the width direction of the box body 100, the rotation axis of the rotating part 520 extends along the width direction of the box body 100, and the center of gravity of the locking member 500 and the handle part 600 after combination tends to drive the hook part 510 and the limiting member 400 to lock.

[0124] The connecting part 530 of the locking member 500 can be located above the limiting member 400, or it can be located below the limiting member 400.

[0125] In some examples, the connecting part 530 is located below the limiting member 400. In this case, in the depth direction of the housing 100, the center of gravity of the locking member 500 and the handle member 600 combined with the hook part 510 are located on both sides of the rotation axis of the connecting part 530. This allows the door 200 to close after the first action is completed, i.e., after the hook part 510 moves downward under the push of the limiting member 400 and the second surface 512 separates from the limiting member 400, the door... As the device 200 continues to approach the housing 100 until the limiting member 400 corresponds to the locking groove 540, due to the opposite distribution of the center of gravity and the hook portion 510, gravity acts on the assembly, generating a clockwise (or counterclockwise) torque around the rotation axis. This torque drives the rotating part 520 to automatically rotate the hook portion 510 upwards, allowing the limiting member 400 to smoothly slide into the locking groove 540 until the first surface 511 of the hook portion 510 tightly abuts against the limiting member 400, completing the locking process. This process eliminates the need for manual operation of the rotating part 520, achieving automated locking of the closing action and significantly improving operational convenience.

[0126] In other examples, the connecting part 530 is positioned above the limiting member. In this case, in the depth direction of the housing 100, the center of gravity of the locking member 500 and the handle 600 combined with the hook part 510 are located on the same side of the rotation axis of the connecting part 530. This allows the door 200 to close after the first action is completed, i.e., after the hook part 510 moves upward under the push of the limiting member 400 and the second surface 512 separates from the limiting member 400, the door... As the body 200 continues to approach the housing 100 until the limiting member 400 corresponds to the locking groove 540, due to the center of gravity being distributed on the same side as the hook part 510, gravity acts on the assembly to generate a clockwise (or counterclockwise) torque around the rotation axis. This torque drives the rotating part 520 to automatically rotate the hook part 510 downwards, allowing the limiting member 400 to slide smoothly into the locking groove 540 until the first surface 511 of the hook part 510 and the limiting member 400 are tightly abutted to complete the locking.

[0127] In both examples, this center-of-gravity layout allows the reverse torque to assist the user in pulling the handle 600 with less effort during unlocking. During device operation, the stable torque balance effectively counteracts the displacement tendency caused by vibration, enhancing the reliability of the door 200 locking. At the same time, the gravity-driven automatic locking mechanism reduces hard friction between components, extends the service life of key components such as the hook part 510 and the limit part 400, reduces maintenance costs, and enables the radio frequency defrosting device 10 to achieve a comprehensive improvement in sealing performance, ease of operation, and structural stability.

[0128] Please see Figure 5 According to some embodiments of this application, the radio frequency defrosting device 10 also includes a seal 300.

[0129] The sealing element 300 is located between the door body 200 and the box body 100. The sealing element 300 seals the gap between the door body 200 and the opening 120 when the door body 200 closes the opening 120.

[0130] A seal 300 is disposed between the door 200 and the housing 100. The seal 300 can be made of a material with good elasticity, such as rubber or silicone, and its shape and size are adapted to the edges of the opening 120 of the door 200 and the housing 100. After the door 200 is closed and the locking member 500 and the limiting member 400 are locked together, the locking force applied by the limiting member 400 to the locking member 500 will press the door 200 against the housing 100, thereby compressing the seal 300. Under pressure, the seal 300 undergoes elastic deformation, filling the gap between the door 200 and the opening 120 of the housing 100, forming a tight sealing structure.

[0131] According to the radio frequency defrosting device 10 provided in the embodiments of this application, the door 200 closes the opening 120 by locking the locking member 500 and the limiting member 400, and under the locking force applied by the locking member 500, the door 200 and the box 100 are pressed together to seal the sealing member 300, thereby improving the sealing effect between the box 100 and the door 200, improving defrosting efficiency, and reducing the probability of radiation leakage and the cost of use.

[0132] Please see Figure 2 and Figure 10 According to some embodiments of this application, the sealing member 300 is disposed on the surface of the door body 200 near the box body 100, the limiting member 400 may be disposed on the side of the box body 100, and the locking member 500 may be disposed on the side of the door body 200 and correspond to the limiting member 400.

[0133] The sealing element 300 is disposed on the surface of the door 200 near the housing 100, which fully utilizes the entire plane of the door 200 facing the housing 100 as a sealing area, providing ample space for the sealing element 300. Compared to some related technologies where the locking element is disposed on the sealing surface of the door, this solution places the locking element 500 on the side of the door 200, completely releasing the surface of the door 200 facing the housing 100, allowing the sealing element 300 to be laid over a large area, thereby significantly increasing the sealing contact area. When the door 200 is closed, the larger sealing element 300, under compression, can more fully fill the gap between the door 200 and the housing 100, effectively improving sealing performance and significantly reducing the risk of radiation leakage.

[0134] The limiting component 400 is located on the side of the housing 100, and the locking component 500 is correspondingly located on the side of the door 200. This layout ensures that the locking force is applied to the side of the door 200. During the locking process between the locking component 500 and the limiting component 400, the locking force can be evenly transmitted to the connection between the door 200 and the housing 100, ensuring balanced force distribution between them. Furthermore, since the locking component 500 does not occupy the sealing surface space of the door 200, there is no need to reserve extra space for it on the mating surfaces of the door 200 and the housing 100. This allows for optimized dimensions of the mating surfaces, reducing unnecessary contact areas. This not only helps to simplify the equipment structure and save space but also reduces the use of manufacturing materials and lowers production costs. In addition, the side-mounted locking component 500 is more convenient to operate; operators can easily lock and unlock the door 200 from the side of the equipment, improving the efficiency and ease of use of the equipment.

[0135] Please see Figure 2 and Figure 10According to some embodiments of this application, the side of the housing 100 facing the door 200 may be provided with a decorative panel 130 surrounding the opening 120, and the sealing member 300 is arranged around the door 200 and corresponds to the decorative panel 130.

[0136] A decorative panel 130 is provided around the opening 120 on the side of the housing 100 facing the door 200. The decorative panel 130 serves two purposes: firstly, it beautifies the appearance of the equipment and enhances the overall visual effect of the radio frequency defrosting device 10; secondly, it provides a regular corresponding sealing surface for the seal 300. The decorative panel 130 can be made of metal, such as stainless steel, which ensures structural strength and facilitates cleaning.

[0137] The sealing element 300 is arranged around the perimeter of the door body 200, corresponding to the decorative panel 130. This arrangement allows the sealing element 300 to precisely fit against the decorative panel 130, forming an effective sealing structure. The sealing element 300 can be made of elastic rubber or silicone. During the closing process of the door body 200, the sealing element 300 is compressed by the door body 200 and the decorative panel 130. Because the sealing element 300 is arranged around the perimeter and closely corresponds to the decorative panel 130, it can evenly fill the gap between the door body 200 and the decorative panel 130, further improving the sealing effect between the door body 200 and the housing 100.

[0138] Please see Figure 2 According to some embodiments of this application, the decorative panel 130 and the locking member 500 may be provided with a relief groove 131.

[0139] The clearance groove 131 on the decorative panel 130 mainly serves to avoid the locking element 500. The shape and size of the clearance groove 131 must be precisely matched with the structure and movement trajectory of the locking element 500. For example, if the locking element 500 is a rotary latch, the clearance groove 131 can be designed as an arc-shaped groove to ensure that the latch will not interfere with the decorative panel 130 during rotation locking or unlocking; when the locking element 500 is an electric push rod structure, the clearance groove 131 can be set as a rectangular groove to ensure that the push rod can extend and retract freely and smoothly complete the locking action with the limiting element 400.

[0140] When the door 200 is closed and the operator operates the locking mechanism 500, the locking mechanism 500 can extend or move unimpeded through the clearance groove 131 area, locking with the limiting member 400 on the side of the housing 100. Simultaneously, the remaining portion of the decorative panel 130 can still tightly align with the sealing members 300 around the door 200. During the process of the locking mechanism 500 applying locking force to press the door 200 against the housing 100, the sealing members 300 are fully compressed, filling the gap between the door 200 and the decorative panel 130, ensuring a good sealing effect.

[0141] According to the embodiments of this application, the decorative panel 130 solves the spatial conflict problem between the decorative panel 130 and the locking member 500, allowing the decorative panel 130, the locking member 500, and the sealing member 300 to each perform their respective functions while cooperating with each other. This maintains the aesthetic effect of the decorative panel 130 on the appearance of the equipment and its auxiliary sealing function for the sealing member 300, while also ensuring the normal operation of the locking member 500. It optimizes the overall structural layout of the radio frequency defrosting device 10, further improves the sealing performance and locking reliability of the equipment, and reduces the probability of malfunctions caused by structural interference, thereby improving the practicality and stability of the equipment.

[0142] Please see Figure 11 According to some embodiments of this application, locking members 500 may be provided on both opposite sides of the door 200, limiting members 400 may be provided on both opposite sides of the box 100, and sealing members 300 may be provided between the two locking members 500.

[0143] Locking components 500 are installed on both opposite sides of the door 200, and limiting components 400 are correspondingly provided on both opposite sides of the box 100. It can be understood that the two sides of the door 200 correspond to the two sides of the box 100, and the locking components 500 and limiting components 400 located on the same side correspond to each other.

[0144] The sealing element 300 is located between the two locking elements 500. When the door 200 is closed, the locking elements 500 on both sides lock into contact with the limiting elements 400 on the sides of the housing 100. During the locking process, the door 200 applies pressure to the housing 100, and the pressure is transmitted from both sides of the door 200 to the center to the sealing element 300, where the sealing element 300 between the two locking elements 500 is fully compressed. Due to the uniform locking force applied from both sides, the sealing element 300 can deform uniformly and tightly fill the gap between the door 200 and the opening 120 of the housing 100.

[0145] This layout ensures that the door 200 receives balanced locking forces from both sides when closed, preventing uneven force from causing the door 200 to tilt or fail to seal properly. The locking elements 500 on both sides work together to enhance the stability of the connection between the door 200 and the housing 100, while the uniform locking force ensures that the sealing element 300 can fully exert its sealing effect, effectively reducing the risk of radio frequency energy leakage.

[0146] Please see Figure 11 and Figure 12 According to some embodiments of this application, the radio frequency defrosting device 10 may further include a handle 600, which is connected to a locking member 500. The handle 600 is used to operate the locking member 500 to lock or disengage from the limiting member 400.

[0147] The handle 600 can be made of a robust and durable metal material, such as stainless steel, or a high-strength engineering plastic. The handle 600 can be tightly fixed to the locking parts 500 on both sides by mechanical connection structures such as bolts and clips. This rigid connection ensures the direct transmission of force, so that when the operator pushes or pulls the handle 600, the force can be transmitted to the locking parts 500 without loss.

[0148] When the door 200 needs to be closed, the operator holds the handle 600 and pushes the door 200 towards the housing 100, continuing to apply force. The handle 600 drives the locking part 500 to move towards the limiting part 400 simultaneously until the locking part 500 and the limiting part 400 are precisely engaged, completing the locking action. When opening the door 200, the operator pulls the handle 600 in the opposite direction. The locking part 500 is disengaged from the limiting part 400 by the handle 600, achieving quick unlocking.

[0149] In some embodiments, there are two locking members 500, and a handle 600 is connected between the two locking members 500.

[0150] The handle 600 can be directly connected to the two locking parts 500 by a mechanical connection. The two ends of the handle 600 can be tightly fixed to the locking parts 500 on both sides by mechanical connection structures such as bolts and buckles.

[0151] In one example, two locking members 500 can be distributed on both sides of the width direction of the door body 200, and the handle member 600 can be located on the lower side of the door body 200. The handle member 600 is located on the lower side of the door body 200 in accordance with ergonomic principles, making it convenient for users to apply force and less likely to cause interference. Moreover, when the door body 200 is closed, the handle member 600 is retracted to the lower side of the door body 200, which is aesthetically pleasing.

[0152] According to the handle 600 provided in this application embodiment, the handle 600 drives the connection of the two locking components 500, ensuring that both sides of the door 200 maintain synchronous movement during locking and unlocking. This ensures that the force on both sides of the door 200 is even, avoiding uneven force or misalignment caused by one side locking or unlocking first, effectively protecting the structure of the door 200. Simultaneously, the even force allows the sealing component 300 to deform evenly and tightly fit the gap under the pressure of the door 200 and the housing 100, maximizing the sealing effect and reducing the risk of radio frequency energy leakage. With its simple and efficient mechanical connection, fast and stable locking and unlocking operations are achieved, simplifying the structure and improving the practicality and reliability of the device.

[0153] Please see Figure 3 and Figure 12According to some embodiments of this application, the side of the door 200 may be provided with a stop surface 213 extending laterally, the stop surface 213 being disposed facing the housing 100, and the locking member 500 being located on the side of the stop surface 213 facing the housing 100, the locking member 500 abutting against the stop surface 213 when unlocked from the limiting member 400.

[0154] The stop surface 213 on the side of the door 200 extends laterally and is disposed toward the box 100. Specifically, in the depth direction of the box 100, the end of the door 200 away from the box 100 is provided with a flange that extends laterally. The surface of the flange facing the box 100 constitutes the stop surface 213. The surface of the flange away from the box 100 is flush with the surface of the door 200 away from the box 100 to ensure the aesthetic appearance of the door 200.

[0155] When the locking member 500 and the limiting member 400 are in the unlocked state, as the door 200 opens, the locking member 500 will gradually move and abut against the stop surface 213. By setting the stop surface 213, the locking member 500 can be effectively prevented from moving excessively or even leaving the predetermined position during the opening of the door 200, thus playing a role in limiting protection.

[0156] The handle 600 is connected between two locking components 500. When opening the door 200, the operator pulls the handle 600, which first unlocks the locking components 500 and the limit component 400. After the locking components 500 abut against the stop surface 213, the operator continues to pull the handle 600. At this time, the handle 600 transmits the force through the locking components 500 to the stop surface 213, and then to the door 200, achieving a smooth opening of the door 200. In this process, the handle 600, the locking components 500, and the stop surface 213 form an efficient force transmission chain, making the operation smoother and less strenuous. At the same time, this design ensures that the locking components 500 are always under control during the opening of the door 200, which not only improves the convenience of operation but also enhances the reliability of the equipment structure, reduces the risk of failure due to loose or abnormal movement of components, and further optimizes the overall performance of the door 200 opening and closing system of the radio frequency defrosting device 10.

[0157] Please see Figure 5 According to some embodiments of this application, the handle 600 is located on one side of the door body 200, and the side of the door body 200 is provided with a stop portion corresponding to the handle 600. The stop portion is used to limit the handle 600 to the starting position.

[0158] Understandably, the stop is located on the side of the handle 600 closest to the housing 100. Specifically, the stop can extend laterally along the door and be spaced apart from the outer surface of the door 200, so that the handle 600 can be retracted to one side of the door 200. Taking the handle 600 located on the lower side of the door 200 as an example, the stop is located on the lower side of the door 200 and extends downward. When the locking member 500 is in the locked position, the handle 600 is in the initial position. At this time, the handle 600 abuts against the stop, and the stop acts as a stop and limit for the handle 600, preventing excessive movement of the handle 600 and affecting the stable cooperation between the locking member 500 and the limiting member 400.

[0159] In some examples, when the door 200 is closed and the locking member 500 and the limiting member 400 are locked together, the surface of the handle 600 is parallel to the outer surface of the door 200, ensuring the overall aesthetics of the radio frequency defrosting device 10.

[0160] Please see Figure 13 , Figure 14 and Figure 15 According to some embodiments of this application, the handle 600 includes a handle portion 610 and an extension portion 620. The extension portion 620 is connected to the side of the handle portion 610 facing the housing 100, and a handle space is formed between the extension portion 620 and the handle portion 610. The extension portion 620 is connected to the locking member 500. Under the action of external force, the handle portion 610 drives the locking member 500 to unlock from the housing 100.

[0161] The handle 600 consists of a latch 610 and an extension 620. The extension 620 is connected to the side of the latch 610 facing the housing 100, forming a latching space between them for easy finger insertion and force application. The latch 610 is ergonomically designed, using non-slip materials such as rubber, with a textured surface for comfortable grip. The extension 620 is connected to the locking element 500 by welding or bolting, ensuring accurate transmission of external force to the locking element 500 when the user operates the handle 600. When the user grips the latch 610 and applies external force, the extension 620 moves the locking element 500, causing the hook 510 to separate from the limiting structure on the housing 100, thus unlocking the door 200. The operation is simple and convenient.

[0162] In actual operation, when items need to be thawed, the user places the items into the receiving cavity 110 of the housing 100, closes the door 200, and initially seals the door 200 and the opening 120 of the housing 100 with the sealing element 300. Then, the locking element 500 locks the door 200 and the housing 100 together. At this point, a closed space is formed inside the radio frequency defrosting device 10, allowing for safe radio frequency defrosting. After defrosting, the user operates the handle 600, applying external force through the handle space. This forces the locking element 500 to unlock via the extension 620, allowing easy access to the door 200 and removal of the items. Throughout the process, the components work together to ensure both the sealing and safety of the device and improve operational convenience, effectively solving the problems existing in the background technology.

[0163] According to the radio frequency defrosting device 10 provided in the embodiments of this application, by setting the locking member 500, the sealing performance of the door 200 after closing is effectively enhanced, and the risk of radio frequency energy leakage is reduced. This not only protects the health and environmental safety of the operator, but also improves the defrosting efficiency. The handle 600 includes a hand-holding part 610 and an extension part 620, forming a hand-holding space that is easy to grip. This conforms to the principles of ergonomics, reduces the difficulty of operation, and allows the user to easily unlock the locking member 500 from the box 100 by applying a small amount of external force. This significantly improves the ease of use, and the simple structure reduces the manufacturing cost, achieving a balance between performance and cost.

[0164] Please see Figure 16 According to some embodiments of this application, the handle 600 may be provided on one side of the door body 200, the handle portion 610 may extend circumferentially along the door body 200, and the extension portion 620 may extend along the depth direction of the box body 100.

[0165] Placing the handle 600 on one side of the door 200 conforms to the user's daily operating habits, facilitating one-handed unlocking and opening of the door 200. This side is typically chosen considering ease of use, spatial layout, and the placement of the locking element 500. The locking element 500 is located on the side of the door 200, and the handle 600 can be placed on the same side of the door 200 where the locking element 500 is located, or it can be placed on the side of the door 200 adjacent to the locking element 500, facilitating connection between the handle 600 and the locking element 500.

[0166] In some examples, the handle 600 can be positioned on the upper or lower side of the door 200. This reduces the space occupied in the width direction and improves usability based on the height of the door 200. When the door 200 is positioned low, the handle 600 can be positioned on the upper side, while when the door 200 is positioned high, the handle 600 can be positioned on the lower side for user convenience. In other examples, the handle 600 can also be positioned on the right side of the door 200 to accommodate most right-handed users, or on the left side of the door 200. The specific placement depends on the actual application scenario and product design.

[0167] The handle 610 extends circumferentially along the door body 200, increasing the grip area for the user and making operation more comfortable and stable. This extension can be linear or curved to better fit the shape of the door body 200. Taking the handle 600 located on the lower side of the door body 200 as an example, the handle 610 can extend along the height of the door body 200 to facilitate operation with the user's fingers.

[0168] The extension 620 extends along the depth direction of the housing 100, effectively transmitting the external force received by the handle 610 to the locking member 500 located on the door 200. The extension 620 and the handle 610 extend in different directions to form a handle space between the extension 620 and the handle 610 for the user's fingers to insert. The length and shape of the extension 620 are reasonably designed according to the interval between the door 200 and the housing 100, or the reserved installation space on the door 200, to ensure the stability of the connection with the locking member 500 and to ensure that the space supported by the extension 620 is sufficient for the user's fingers to insert.

[0169] Please see Figure 15 and Figure 16 According to some embodiments of this application, the extension 620 may be provided at one end of the handle 610 near the door body 200.

[0170] The handle 610 extends circumferentially along the door body 200 to provide a handle area for the user. Positioning the extension 620 near the end of the door body 200 maximizes the usable width of the handle 610. This avoids the extension 620 occupying the middle of the handle 610, ensuring ample space for the user's fingers to grip, conforming to human hand size and operating habits.

[0171] For example, if the handle 610 is located on the lower side of the door body 200 and extends along the height direction of the door body 200, the width of the handle 610 in the height direction of the door body 200 is the area where the user can grip the handle. If the extension 620 is located at the end of the handle 610 near the door body 200, that is, at the top of the handle 610 in the height direction of the door body 200, the space available for the user to grip the handle is larger when the user extends the handle space upward from the bottom of the handle 610.

[0172] The extension 620 and the handle 610 can be connected by welding, bolting, or integral molding. For example, when the plastic handle 600 is manufactured using an integral molding process, the continuous structure of the extension 620 and the handle 610 can be directly formed; if a metal material is used, aluminum alloy can be extruded, which is lightweight and has high structural strength, without affecting the overall structural stability.

[0173] The extension 620 is positioned at the end of the handle 610 closest to the door body 200, effectively solving the problem of insufficient gripping space for the handle 610. Through this rational layout, the effective gripping area of ​​the handle 610 is maximized, meeting the user's finger gripping needs and improving comfort and stability during operation. Simultaneously, it ensures efficient transmission of external force from the handle 610 to the locking element 500, avoiding inconvenience and force loss due to limited gripping space, making unlocking operations easier and smoother. This further optimizes the user experience of the radio frequency defrosting device 10, enhancing the product's practicality and user-friendly design.

[0174] Please see Figures 13 to 16 According to some embodiments of this application, the surface of the handle 610 near the housing 100 may be provided with a protrusion 611, which is located at the end of the handle 610 away from the door 200.

[0175] The protrusion 611 increases the friction between the handle 610 and the user's fingers. Its material can be the same as the handle 610; if the handle 610 is made of plastic or aluminum alloy, the protrusion 611 can be a one-piece molded plastic structure or aluminum alloy; if the handle 610 is wrapped in rubber, the protrusion 611 can also be made of rubber. The protrusion 611 can have various shapes, such as round, oval, or strip-shaped, and different shapes of protrusion 611 can provide different tactile sensations.

[0176] The protrusion 611 is positioned at the end of the handle 610 furthest from the door body 200, conforming to the force distribution of the user's fingers during operation. When the user grips the handle 610, their fingers naturally apply greater force at the end furthest from the door body 200. The protrusion 611, positioned here, better increases friction. This enhances the stability of the user's grip on the handle 610 and reduces the likelihood of difficulty unlocking due to finger slippage during operation.

[0177] Please see Figure 15 According to some embodiments of this application, the surface of the protrusion 611 away from the handle portion 610 is connected to the handle portion 610 by an arc-shaped transition surface.

[0178] The curved surface can be circular or elliptical, etc., with no specific limitation. The curvature of the curved surface is determined based on a combination of ergonomics and manufacturing processes to ensure a natural and smooth transition while facilitating production. For example, a smaller curvature results in a smoother transition, while a larger curvature creates a more pronounced rounded effect. For instance, the radius of curvature can be set to 3mm-8mm, or other radii, without limitation. This design without sharp edges prevents users' fingers from being scratched during gripping, while also reducing stress concentration and enhancing the structural strength of the handle component 600.

[0179] When a user grips the handle 610 to unlock the door, their fingers come into contact with the transitional curved surface of the protrusion 611 and the handle 610. Due to the smooth transition and absence of sharp edges, the fingers are not scratched or pricked during contact, allowing for comfortable force application. Simultaneously, the curved surface reduces stress concentration caused by sharp edges, making the handle 600 less prone to damage during long-term use. This ensures the stability and reliability of the force transmitted from the handle 610 to the locking element 500, thus smoothly unlocking the door 200.

[0180] Please see Figure 12 According to some embodiments of this application, the locking member 500 can be installed on the first side 230 of the door body 200, and the handle member 600 can be provided on the second side 240 of the door body 200 adjacent to the first side 230 and extend along the length direction of the second side 240. The end of the extension 620 in the length direction of the second side 240 is connected to the locking member 500.

[0181] With the user facing the door 200 as a reference, the first side 230 can be either the left or right side of the door 200, depending on the overall layout and operating habits of the radio frequency defrosting device 10. The locking component 500 can be installed on the first side 230 of the door 200 by means of bolt fixing, pin connection, or slot snap-fit. For example, when using bolt fixing, a mounting hole is opened in the first side 230 of the door 200, and the locking component 500 is fixed to the door 200 by bolts passing through the mounting hole; when using pin connection, corresponding pin holes are provided on the door 200 and the locking component 500, and the connection is achieved by inserting the pin, so that the locking component 500 can rotate or slide relative to the door 200.

[0182] The second side 240 is adjacent to the first side 230. Taking the first side 230 as the left side of the door 200 as an example, the second side 240 can be the upper or lower side of the door 200. The handle 600's grip portion 610 extends along the length of the second side 240 to increase the area available for the user to grip, making it easier for the user to operate the handle 600 from various positions. Taking the handle 600 as the lower side of the door 200 as an example, the handle 600 can extend along the width of the door 200. That is, the length of the grip portion 610 extends along the width of the door 200, and the width of the grip portion 610 extends along the height of the door 200, greatly increasing the coverage area of ​​the grip portion 610.

[0183] There are various ways to connect the end of the extension 620 to the locking member 500, such as welding, threaded connection, snap-fit ​​connection, etc., which are not specifically limited here. By setting both the locking member 500 and the handle member 600 on the side of the door body 200, the space occupied on the front of the door body 200 is reduced, the overall space design is optimized, the integrity of the door body 200 is better, the arrangement of the sealing member 300 is convenient, and it is also convenient to install other components inside the door body 200.

[0184] Please see Figure 12 and Figure 15 In some embodiments, the locking member 500 is rotatably mounted on the first side 230 of the door body 200, and the extension 620 is arranged in an arc shape near the surface of the door body 200.

[0185] The handle 600 unlocks the door 200 by rotating the locking member 500. Since the extension 620 is located at the end of the handle 610 near the door 200, the surface of the extension 620 near the door 200 is designed to be arc-shaped to avoid the edge of the door 200 when the handle 600 moves, reducing the risk of interference. It also reduces the assembly gap between the handle 600 and the door 200, improving aesthetics.

[0186] Please see Figures 13 to 15According to some embodiments of this application, the locking member 500 may be provided with a plurality of first positioning portions 531, and the end of the extension portion 620 in the length direction of the second side portion 240 may be provided with a plurality of second positioning portions 621 corresponding to the plurality of first positioning portions 531, and the plurality of first positioning portions 531 and the plurality of second positioning portions 621 are connected accordingly.

[0187] By providing multiple first positioning portions 531 on the locking member 500 and cooperating with multiple second positioning portions 621 on the extension portion 620, a stable connection between the locking member 500 and the extension portion 620 is achieved. It is understood that the number, position, and shape of the second positioning portions 621 correspond one-to-one with the first positioning portions 531, ensuring the accuracy and stability of the connection. The stability of the connection is improved by providing multiple first positioning portions 531 and multiple second positioning portions 621.

[0188] In some examples, the first positioning part 531 can be a countersunk hole, located on the side of the locking member 500 opposite to the extension 620. The countersunk hole design allows the screw head to be recessed into it, ensuring a flat surface after connection and preventing interference or disruption caused by a protruding screw head. The second positioning part 621 can be a threaded hole, and the two are fixedly connected by screwing a screw through the countersunk hole into the threaded hole. The size of the threaded hole matches the screw to ensure a tight connection.

[0189] The number of countersunk holes can be set to two or more to meet different size and force requirements. For example, when the locking part 500 and the extension 620 are large in size and subject to greater force, more than two countersunk holes can be set to enhance the connection stability. When the size of the extension 620 is limited, two countersunk holes can be set to ensure the stability of the connection.

[0190] In other examples, the first positioning part 531 can also be a positioning boss, and the second positioning part 621 can be a groove. The boss can be inserted into the corresponding groove of the extension part 620 to play the role of positioning and initial fixation; or both the first positioning part 531 and the second positioning part 621 can be positioning pin holes. By inserting a positioning pin and cooperating with the pin hole on the extension part 620, precise positioning and connection can be achieved.

[0191] By providing multiple corresponding positioning parts in the locking member 500 and the extension 620 and connecting them to each other, the stability and reliability of the connection between the handle 600 and the locking member 500 in the radio frequency defrosting device 10 are significantly improved. The multi-point connection method can distribute the force, avoid local stress concentration, and extend the service life of the components. Furthermore, the design of the first positioning part 531 and the second positioning part 621 facilitates installation and disassembly, which is beneficial for product manufacturing and subsequent maintenance, further enhancing the overall performance and market competitiveness of the product.

[0192] Please see Figures 13 to 15According to some embodiments of this application, the handle portion 610 may be provided with a receiving groove 612 on the side facing the extension portion 620, and at least a portion of the extension portion 620 may extend into the receiving groove 612.

[0193] Given the limited space in the handle 600 design, a receiving groove 612 is provided on the side of the handle portion 610 facing the extension portion 620 to ensure connection strength and make reasonable use of space. The shape and size of the receiving groove 612 are determined according to the size and shape of the first positioning portion 531, and can be designed as a rectangular or circular groove, etc. Its depth and width must be able to accommodate at least part of the structure of the extension portion 620 and the first positioning portion 531 to meet the requirements of installing the connector.

[0194] At least a portion of the extension 620 can extend into the receiving groove 612. When the cross-sectional area of ​​the extension 620 is small, it is difficult to meet assembly requirements, meaning the first positioning part 531 cannot be fully assembled. The space of the receiving groove 612 is used to increase the cross-sectional area of ​​the extension 620 for assembly. For example, when the first positioning part 531 is a countersunk hole, a portion of the countersunk hole structure can extend into the receiving groove 612. Simultaneously, the design of the receiving groove 612 facilitates the screw's connection to the threaded hole on the extension 620 by passing through the countersunk hole and utilizing the space of the receiving groove 612. In another example, when the first positioning part 531 is a positioning boss or a positioning pin hole, the space of the receiving groove 612 can also be used for installation and connection, enhancing the stability of the connection.

[0195] According to the embodiment of this application, the receiving groove 612, on the one hand, makes full use of the space of the handle part 610 by allowing the extension part 620 and the first positioning part 531 to extend into the receiving groove 612, avoiding connection problems caused by the small cross-section of the extension part 620, enhancing the connection strength between the extension part 620 and the locking member 500, and ensuring that the connecting part 530 will not loosen or be damaged during frequent operation. On the other hand, this design avoids increasing the size of the extension part 620 or other components to meet the connection strength requirements, thereby reducing the space occupied by the entire handle part 600, making the structure of the radio frequency defrosting device 10 more compact and reasonable, and improving the overall design level and practicality of the product.

[0196] Please see Figures 13 to 15 According to some embodiments of this application, the receiving groove 612 and the handle portion 610 may be spaced apart at the ends of the second side portion 240 in the length direction.

[0197] Specifically, the length of the handle portion 610 is greater than the length of the extension portion 620, so that the end of the extension portion 620 is spaced apart from the end of the handle portion 610, and the receiving groove 612 is provided between the end of the handle portion 610 and the end of the extension portion 620.

[0198] Understandably, because the design of the receiving groove 612 reduces the thickness of the handle 610, if the receiving groove 612 extends to the end of the handle 610, the edge thickness of the handle 610 will be too thin, which may weaken the structural strength of the end of the handle 610, making the end easy to damage during use, and may also affect the feel or even cause safety hazards. The spacing between the receiving groove 612 and the end of the handle 610 can ensure that the thickness of the area accessible to the user is not too thin, thus improving the user experience.

[0199] Please see Figure 12 According to some embodiments of this application, two locking members 500 may be provided, the door body 200 has a third side 250 opposite to the first side 230, the two locking members 500 may be respectively installed on the first side 230 and the third side 250, and the extension 620 may be connected between the two locking members 500.

[0200] By setting two locking elements 500, the door 200 and the housing 100 can be locked simultaneously from opposite sides, making the locking force distribution more even. Taking the first side 230 as the left side of the door 200 as an example, the third side 250 is the right side of the door 200. The extension 620 connects between the two locking elements 500, forming a stable connection structure. This allows the force to be transmitted to both locking elements 500 simultaneously when the user operates the handle 600, thereby driving the two locking elements 500 to move synchronously, improving the convenience and efficiency of operation. This design also enhances the stability of the door 200, making it more durable during frequent opening and closing, and improving the overall performance and reliability of the product.

[0201] Please see Figure 14 and Figure 15 According to some embodiments of this application, both locking members 500 may be provided with a first anti-fooling part 532, and the positions of the first anti-fooling parts 532 on the two locking members 500 are different. The handle part 610 is provided with two second anti-fooling parts 613 corresponding to the positions of the two first anti-fooling parts 532. The first anti-fooling parts 532 and the corresponding second anti-fooling parts 613 cooperate to limit the movement.

[0202] Two locking members 500 are respectively installed on the first side 230 and the third side 250 of the door body 200. Due to the design of the connection structure between the locking member 500 and the extension 620, there are slight differences in the structure of the left and right locking members 500. Taking the first positioning part 531 as a countersunk hole as an example, the countersunk holes of the two locking members 500 are located in different directions. Therefore, to avoid installation errors, a first anti-fooling part 532 is provided on both locking members 500, and the positions of the first anti-fooling parts 532 on the two locking members 500 are different. The handle part 610 is provided with two second anti-fooling parts 613 corresponding to the positions of the two first anti-fooling parts 532. The shape and size of the second anti-fooling parts 613 are adapted to the first anti-fooling parts 532 to achieve precise matching and limiting.

[0203] The specific form of the first foolproof part 532 and the second foolproof part 613 is not limited, and they can be different forms of cooperation such as protrusions, grooves, and notches.

[0204] For example, the first anti-foolproof portion 532 of the two locking members 500 can be a protrusion, and the two second anti-foolproof portions 613 of the handle portion 610 are grooves that can accommodate the protrusion. Specifically, the protrusion can be provided at one end of the locking member 500 facing the handle portion 610, and the protrusion position on the locking member 500 located on the first side portion 230 is higher than the protrusion position on the locking member 500 on the second side portion 240. The positions of the grooves at both ends of the handle portion 610 correspond to the two protrusions.

[0205] During installation, when the worker assembles the handle 600 with the two locking parts 500, the installation can only be completed when the two first anti-misalignment parts 532 are correctly engaged with their corresponding second anti-misalignment parts 613. If the installation is incorrect, the first anti-misalignment parts 532 and the second anti-misalignment parts 613 will not be able to engage, hindering the installation process and thus preventing incorrect installation. During normal use, the engagement limit of the first anti-misalignment parts 532 and the second anti-misalignment parts 613 further ensures the relative position stability between the handle 610 and the locking parts 500, ensuring that when the user operates the handle 610, the force can be accurately transmitted to the two locking parts 500, achieving normal unlocking and locking of the door 200.

[0206] The foolproof design makes the installation process more intuitive and simpler. Workers do not need to spend a lot of time distinguishing the subtle differences between the left and right locking parts 500, reducing the probability of installation errors, thereby improving product assembly efficiency and reducing production costs. Correct installation ensures the connection stability between the handle 610 and the locking part 500, making the unlocking and locking operations of the door 200 more reliable. It reduces problems such as poor force transmission and insecure locking caused by installation errors, extends the product's service life, and improves the overall quality and reliability of the product.

[0207] Please see Figure 16 and Figure 17 According to some embodiments of this application, the door 200 or the box 100 is provided with a limiting groove 211.

[0208] 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, ensuring both strength and good shielding performance. The door 200 or housing 100 is provided with a limiting groove 211, which can be a recessed structure formed on the edge of the door 200 or housing 100, the shape and size of which are adapted to the embedded portion 320 of the seal 300. The limiting groove 211 provides positioning and fixation for the embedded portion 320 of the seal 300, ensuring the stability of the seal 300 installation.

[0209] The sealing element 300 is located on the side of the door 200 near the box 100, or on the side of the box 100 near the door 200. The sealing element 300 includes a main body 310 and an embedded part 320. The embedded part 320 is connected to the main body 310. The main body 310 is installed on the door 200 or the box 100. The embedded part 320 is embedded in the limiting groove 211.

[0210] The main body 310 of the seal 300 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 and the door 200 when the door 200 is closed. The insert 320 can be integrally molded with the main body 310, or it can be connected by bonding or other methods. The insert 320 is designed to fit precisely into the limiting groove 211; for example, it can be a raised strip or block-shaped structure.

[0211] When the door 200 is closed, the main body 310 fits tightly between the edge of the opening 120 of the housing 100 and the door 200, sealing the receiving cavity 110, improving radio frequency defrosting efficiency, and preventing radio frequency energy leakage. The embedded part 320 is embedded in the limiting groove 211, making the connection between the seal 300 and the door 200 or the housing 100 more stable, preventing easy displacement or detachment, improving the assembly stability of the seal 300, thereby enhancing the sealing performance between the housing 100 and the door 200 and reducing the probability of radiation leakage. At the same time, due to the embedded assembly, the seal 300 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.

[0212] According to the embodiment of this application, the radio frequency defrosting device 10, through the structural design of the sealing element 300, uses the main body 310 to seal the gap between the door body 200 and the opening 120 of the box body 100. By setting the embedded part 320 and the limiting groove 211 to cooperate, the assembly stability of the sealing element 300 is improved, thereby improving the sealing effect between the box body 100 and the door body 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 300, which is convenient for subsequent replacement and maintenance, improves maintenance efficiency, and reduces maintenance costs.

[0213] In some embodiments, the seal 300 may be conductive so that when the door 200 is closed, the metal part of the door 200 is connected to the housing 100 through the seal 300, thereby forming a complete shielding barrier and improving the shielding effect against radio frequency energy.

[0214] For example, the seal 300 can be made of a conductive material, such as silicone or silicone mixed with conductive particles to achieve conductivity; or, the seal 300 can be a composite form including an elastic sealing part and a conductive part, using the deformation of the elastic sealing part to achieve sealing, and using the conductive part to achieve conductivity between the box 100 and the door 200.

[0215] Please see Figure 16 and Figure 17 According to some embodiments of this application, the door 200 is provided with a limiting groove 211, and the sealing member 300 is provided on the side of the door 200 near the box 100.

[0216] By setting the seal 300 on the door 200, the edge of the opening 120 of the box 100 is relatively flat, making it less likely for items to come into contact with or interfere with the seal 300 when taking them out or putting them in, thus improving ease of use and durability of the seal 300.

[0217] Please see Figure 16 and Figure 17 According to some embodiments of this application, the width of the main body 310 may have a decreasing trend in the direction away from the door body 200.

[0218] The design of the main body 310, which decreases in width away from the door 200, allows the main body 310 to better fit 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 310 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 310 can be arc-shaped and protruding, which can also achieve the same effect of the width gradually decreasing away from the door 200.

[0219] In actual operation, the narrower portion of the main body 310 directly contacts the edge of the opening 120 of the housing 100. When the door 200 is closed, the gradually narrowing main body 310 deforms more significantly as it is compressed against the seal 300, 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 310 experiences more even stress when compressed, further enhancing the sealing effect.

[0220] According to the embodiment of this application, the main body 310 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, and seal more tightly, thereby further improving the sealing performance between the box 100 and the door 200, reducing the risk of radiation leakage, and at the same time giving full play to the sealing performance of the sealing element 300, ensuring the stable operation of the radio frequency defrosting device 10.

[0221] Please see Figure 16 and Figure 17 According to some embodiments of this application, the surface of the main body 310 on the side away from the door body 200 may include an arcuate surface.

[0222] The curved surface can prevent stress concentration when the main body 310 contacts 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.

[0223] In some examples, taking the cross-section of the main body 310 in the aforementioned embodiment as approximately trapezoidal and the bottom of the main body 310 being far from the door 200 as an example, the bottom edge of the main body 310 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 310 facing the box 100 is formed by splicing three arc surfaces; in other examples, the surface of the main body 310 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 310.

[0224] The main body 310 with its curved surface gradually flattens as the door 200 closes, compressing the seal 300 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 611 through its own deformation, achieving a tighter seal.

[0225] According to the embodiments of this application, an arc-shaped surface is provided on the main body 310, which enhances the fit between the main body 310 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.

[0226] Please see Figure 16 and Figure 17 According to some embodiments of this application, the main body 310 may be hollow.

[0227] The hollow structure of the main body 310 can take many forms. For example, the main body 310 can be a thin-walled structure with a single cavity inside, or it can have multiple hollow elongated cavities arranged side by side inside the main body 310, or it can have a honeycomb hollow structure inside the main body 310.

[0228] When the door 200 is closed, the hollow main body 310 is compressed by the edge of the opening 120 of the housing 100. Due to the hollow interior of the main body 310, 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 310 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.

[0229] According to the embodiments of this application, the main body 310 is hollow, which allows the sealing element 300 to maintain a certain strength while possessing better elasticity and deformation capacity. Compared with a solid main body 310, it can more effectively seal the gap between the door 200 and the housing 100, significantly improving the sealing performance between the housing 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 300, reduce production costs, and to a certain extent reduce the weight of the sealing element 300, facilitating subsequent installation and replacement, improving maintenance efficiency, and reducing maintenance costs.

[0230] According to some embodiments of this application, the main body 310 may be provided with a vent hole that communicates with its hollow portion.

[0231] 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.

[0232] The vent is directly connected to the hollow portion of the main body 310. During the closing process of the door 200, the seal 300 is compressed, and air in the hollow portion is discharged through the vent. This allows the main body 310 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 310 quickly return to its original shape, facilitating the next sealing operation.

[0233] According to the embodiments of this application, a vent hole communicating with the hollow part of the main body 310 is provided, which can effectively improve the air circulation of the seal 300 during the pressure and recovery process, avoid the problem of the main body 310 being obstructed or recovering slowly due to air accumulation, further improve the sealing efficiency and service life of the seal 300, 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 300 more flexible and convenient.

[0234] Please see Figure 16 and Figure 17 According to some embodiments of this application, the surface of the main body 310 near the door 200 can be flush with the surface of the embedded part 320 near the door 200.

[0235] The surface of the main body 310 near the door 200 is flush with the surface of the embedded part 320 near the door 200, making the overall appearance of the seal 300 more regular when it is installed on the door 200, and ensuring a tighter and more uniform fit between the seal 300 and the door 200.

[0236] When the seal 300 is installed onto the door 200, because the corresponding surfaces of the main body 310 and the embedded part 320 are flush, the force between the seal 300 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 300 installation. Furthermore, this flush structural design allows the main body 310 and the embedded part 320 to deform collaboratively when the seal 300 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.

[0237] In some examples, the surface of the main body 310 near the door 200 is flush with the surface of the embedded part 320 near the door 200, and the width of the main body 310 tends to decrease in the direction away from the door 200, so that the overall cross-section of the seal 300 is similar to a P-shape.

[0238] The sealing element 300 provided in the embodiments of this application ensures a tight fit between the sealing element 300 and the door body 200, and enhances the stability and reliability of the overall installation of the sealing element 300.

[0239] Please see Figure 10 and Figure 18 According to some embodiments of this application, the sealing member 300 may be arranged around the door body 200 and correspond to the periphery of the opening 120, and the embedded part 320 is provided on the side of the main body 310 facing the center of the door body 200.

[0240] The sealing element 300 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 300 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.

[0241] In some examples, the seal 300 can be a one-piece molded closed annular frame.

[0242] In other examples, the seal 300 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 300 may include four segments corresponding to the four sides of the door 200.

[0243] Due to the limited area of ​​the door 200, the embedded part 320 is located on the inside, allowing the main body 310 to occupy a larger space. The larger main body 310 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 310 can better fit the edge of the opening 120 of the enclosure 100, effectively blocking radio frequency energy while improving the sealing effect.

[0244] In some embodiments, the embedding portion 320 may also be disposed on the side of the main body portion 310 away from the center of the door body 200.

[0245] 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 320 on the side of the main body 310 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 320 of the seal 300 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 300, thereby smoothly achieving the assembly of the seal 300.

[0246] 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, setting the embedded part 320 on the side of the main body 310 away from the center of the door 200 can reserve more space inside the door 200, avoid the embedded part 320 occupying the space near the center of the door 200, and facilitate the layout and installation of internal components.

[0247] 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 310 near and away from the center of the door body 200, so that the seal 300 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 310, the installation stability of the seal 300 is further guaranteed.

[0248] 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.

[0249] 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.

[0250] Please see Figure 16 and Figure 17 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.

[0251] 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.

[0252] Please see Figures 16 to 18 According to some embodiments of this application, the door body 200 may be provided with an installation groove 212, the main body 310 may be installed in the installation groove 212, and the limiting groove 211 may communicate with the installation groove 212.

[0253] The mounting groove 212 provided on the door body 200 provides installation and positioning space for the main body 310 of the seal 300. 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 310 of the seal 300, so as to tightly wrap the main body 310. For example, the cross-section of the mounting groove 212 can be rectangular, fitting with the side of the main body 310 facing the door body 200. The main body 310 is installed in the mounting groove 212 and can be bonded with adhesive to further tighten the fit between the main body 310 and the inner wall of the mounting groove 212.

[0254] The limiting groove 211 communicates with the mounting groove 212, allowing the insert 320 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 320. When the seal 300 is installed, as the main body 310 is placed in the mounting groove 212, the insert 320 can slide into the limiting groove 211 along the communicating channel, completing the entire installation process of the seal 300. The installation is simple and highly stable.

[0255] When the door 200 is closed, the main body 310 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 310 will not shift, thus stably performing its sealing function. At the same time, the embedded part 320 is embedded in the limiting groove 211, further enhancing the assembly stability of the seal 300. The two work together to make the connection between the seal 300 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 300. When the seal 300 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.

[0256] Please see Figure 18 The door body 200 may include a main body 210 and a panel 220. The limiting groove 211 is provided on the side of the main body 210 facing the box 100. The main body 210 is made of metal and is integrally formed. The panel 220 is installed on the side of the main body 210 away from the box 100.

[0257] 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 shielding space, effectively blocking the leakage of radio frequency energy. Simultaneously, the integral molding process allows the surface of the main board 210 facing the enclosure 100 to maintain a high degree of flatness. The limiting groove 211 is located on the side of the main board 210 facing the enclosure 100. Due to the flat surface of the main board 210, the dimensional accuracy of the limiting groove 211 is easier to ensure, allowing for a more precise fit with the embedded part 320 of the sealing element 300.

[0258] 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.

[0259] In some examples, the door 200 may also include an upper decorative panel and a lower decorative panel. The upper decorative panel 130 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.

[0260] Compared to related technologies that use a plastic main body 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 a plastic main body, 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, improving production efficiency, and avoiding the problem of reduced sealing performance caused by uneven structure, further ensuring the sealing and reliability of the radio frequency defrosting device 10.

[0261] Please see Figure 19 This application embodiment also provides an electrical device 1, which includes the radio frequency defrosting device 10 described above.
