[0059] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0061] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0062] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0063] In the related art, the antenna plate is fixedly assembled on the bottom of the corresponding box by a plurality of support columns arranged at intervals. The purpose of setting a plurality of support columns is to ensure the parallelism between the antenna plate and the bottom of the corresponding box. However, since the plurality of support columns are independent of each other, when multiple batches are produced and supplied, three support columns from different batches may jointly fix and support an antenna plate. Since the sizes of the support columns may be inconsistent, the antenna plate is not parallel to the bottom of the corresponding box, which affects the thawing effect. In addition, if the plurality of support columns are directly connected together, the size error may cause the support columns to pull and tilt against each other during assembly, which not only affects the efficiency of antenna assembly, but also affects the parallelism between the antenna plate and the bottom of the corresponding box.

[0064] Based on the above technical problems, the applicant designed an antenna pole plate mounting assembly to solve the technical problems of complex assembly process and poor assembly efficiency during the installation of the antenna pole plate to a certain extent, and to ensure the parallelism of the antenna pole plate and the bottom surface of the corresponding box.

[0065] Figure 1 FIG. 1 is a schematic diagram showing the structure of the antenna plate mounting assembly in some embodiments. Figure 1 An embodiment of the present application provides an antenna pole plate mounting assembly, which includes a support column 100 and a first connecting member 200. A plurality of support columns 100 are arranged at intervals, and a support column 100 is connected to at least one adjacent support column 100 through the first connecting member 200 so that the plurality of support columns 100 form an integral structure.

[0066] Figure 2 The antenna plate is shown through Figure 1 The installation diagram of the antenna plate mounting assembly shown in FIG. Figure 3 Shows Figure 2 Explosion diagram of . Figure 2-Figure 3 Through the antenna pole plate mounting assembly provided in the embodiment of the present application, the antenna pole plate 400 can be installed on the bottom surface of the corresponding box 300 through multiple support columns 100. Since one support column 100 and at least one adjacent support column 100 are connected by a first connecting member 200, multiple support columns 100 can form an integral structure to ensure the consistency of the support columns 100, so as to avoid the phenomenon that the antenna pole plate 400 is not parallel to the bottom surface of the corresponding box 300 during installation, thereby improving the thawing effect. During assembly, multiple support columns 100 can be taken and placed as a whole to improve the convenience of installing the antenna pole plate 400 and improve assembly efficiency.

[0067] Combination Figure 1-Figure 3 In some embodiments, three support columns 100 may be provided, and the three support columns 100 may be arranged in a triangle. Two adjacent support columns 100 are connected by a first connecting member 200, that is, three first connecting members 200 are also provided. The three support columns 100 are connected into an integral structure by the three first connecting members 200. When assembling the antenna plate 400, the integral structure can be placed as a whole on the bottom surface of the box 300 to be assembled, and the integral structure can be fixed to the bottom surface of the box 300 by bolts or the like.

[0068] In some embodiments, the first connector 200 is elastic. During assembly, if there is a size error, which causes the support columns 100 to pull and tilt against each other, the elastic first connector 200 will deform accordingly to adapt to the pull and tilt between the support columns 100 caused by the size assembly error, so that the support columns 100 can be kept as vertical as possible, so as to improve the parallelism between the antenna plate 400 and the bottom surface of the corresponding box 300 and improve the thawing effect.

[0069] In some embodiments, the first connector 200 is preferably made of a non-polar plastic material to insulate the first connector 200 and avoid interference. The first connector 200 is preferably curved. When there is a dimensional error that causes the support columns 100 to pull and tilt against each other, the curved first connector 200 can have more deformation space to better adapt to the pulling and tilting of the support columns 100 caused by dimensional assembly errors, so that the support columns 100 can be kept as vertical as possible to improve the parallelism of the antenna plate 400 and the bottom surface of the corresponding box 300, thereby improving the thawing effect.

[0070] In some embodiments, the first connecting member 200 may be wavy ( Figure 1 That is, the first connecting member 200 may be in the shape of a wave, an arc or a sawtooth, or a combination of any two or three of them, which is not limited here.

[0071] It should be noted that since the turning point of the wavy or arc-shaped first connecting member 200 is through a curve transition, and the turning point of the sawtooth-shaped first connecting member 200 is through a straight line transition, during implementation, the first connecting member 200 with a curve transition is less likely to break than the first connecting member 200 with a straight line transition, which can improve the yield of product assembly and thus improve the assembly effect.

[0072] Combination Figure 2-Figure 3 In implementation, a bolt hole may be provided at the bottom end of the support column 100, and a connection hole 310 may also be provided on the bottom surface of the corresponding box 300, so that the support column 100 may be fixed to the bottom surface of the corresponding box 300 by screw connection. If the antenna plate 200 is not installed horizontally, the screws may be fine-tuned until the antenna plate 200 is horizontal.

[0073] Combination Figure 1In some embodiments, a plurality of fins 110 may be spaced apart at the end of the bottom of the support column 100 along the circumferential direction, and a positioning member 120 is connected to the outer side of each fin 110, and the bottom end of the positioning member 120 may protrude from the bottom end of the support column 100. During assembly, the positioning member 120 may be first inserted into the positioning hole on the bottom surface of the corresponding box 300 to achieve preliminary positioning of the antenna pole plate mounting assembly, and then the support column 100 may be fixed to the bottom surface of the corresponding box 300 by means of screw assembly.

[0074] Combination Figure 1-Figure 3 In some embodiments, the positioning member 120 may include a first positioning column 121 and a positioning boss 122. The first positioning column 121 is connected to the outer side of the fin 110, and the positioning boss 122 is connected to the bottom end of the first positioning column 121. The positioning boss 122 protrudes from the bottom end of the support column 100. During implementation, a positioning hole 320 is correspondingly provided on the bottom surface of the box body 300. The positioning boss 122 is inserted into the positioning hole 320 on the bottom surface of the corresponding box body 300 to achieve preliminary positioning of the antenna plate mounting assembly.

[0075] Combination Figure 1 In some embodiments, the positioning boss 122 may be in the shape of a cone, and the bottom diameter of the positioning boss 122 is smaller than the top diameter of the positioning boss 122, that is, the positioning boss 122 is in the shape of an inverted cone, so that the positioning boss 122 can be quickly inserted into the positioning hole on the bottom surface of the corresponding box 300.

[0076] In other embodiments, the positioning boss 122 may also be wedge-shaped or conical, etc., which is not limited here.

[0077] In some embodiments, the bottom end of the first positioning column 121 is preferably in the same plane as the bottom end of the supporting column 100. When the first positioning column 121 is assembled in place, it is possible to determine whether the bottom end of the first positioning column 121 and the bottom end of the supporting column 100 are in the same plane by checking whether there is a gap between the bottom end of the first positioning column 121, the bottom end of the supporting column 100 and the bottom surface of the corresponding wall, so as to maintain the verticality of the supporting column 100 and the bottom of the corresponding box 300, so as to further improve the parallelism of the antenna plate 400 and the bottom surface of the corresponding box 300.

[0078] In some embodiments, the first connector 200 and the connected support column 100 are connected via fins 110 and positioning members 120. The first connector 200, the support column 100 connected to the first connector 200, and the corresponding fins 110 and positioning members 120 are preferably integrally formed, that is, the antenna pole plate mounting assembly is preferably manufactured in one piece to ensure the integrity of the entire device.

[0079] In other embodiments, the first connecting member 200 may also be directly formed on the peripheral surface of the connected supporting column 100, which is not limited here.

[0080] Combination Figure 1 In some embodiments, a plurality of first clips 130 are provided at the top end of the support column 100 and are arranged at axial intervals around the support column 100. The outer peripheral surface of the first clip 130 is arc-shaped, and a groove is provided in the middle of the first clip 130. The grooves of the plurality of first clips 130 form a first positioning groove 132 for clamping the antenna pole plate 400, and the antenna pole plate 400 is clamped in the first positioning groove 132. In a specific implementation, a first snap-in hole 401 corresponding to the support column 100 is provided on the antenna pole plate 400. The antenna pole plate 400 is placed on the top of multiple support columns 100 so that the top of the support column 100 faces the corresponding first snap-in hole 401 on the antenna pole plate 400. The antenna pole plate 400 is pressed down, and the multiple first fasteners 130 at the top of the support column 100 shrink inward, and the antenna pole plate 400 is embedded in the groove from the top of the first fastener 130. Subsequently, the multiple fasteners 130 at the top of the support column 100 are reset to prevent the antenna pole plate 400 from falling off the fastener 130, thereby improving the stability of the antenna pole plate 400 after assembly.

[0081] Combination Figure 1 In some embodiments, four first fasteners 130 may be provided at the top of a support column 100, and the four first fasteners 130 form a circular ring, the diameter of the circular ring may be consistent with the diameter of the support column 100, and a first guide slope 131 may be provided at the top of the outer peripheral surface of the first fastener 130, and the top of the first guide slope 131 extends in the axial direction of the support column 100, thereby providing guidance for the assembly of the antenna plate 400 on the first fastener 130.

[0082] The antenna pole plate mounting assembly provided in the embodiment of the present application uses a first connecting member 200 to fix a plurality of independent support columns 100 together, which not only ensures the consistency of the support columns 100, but also avoids the problem of the support columns 100 being pulled and tilted against each other, making assembly more convenient.

[0083] In addition, the antenna pole plate and the tuning plate are two important components required for RF heating. The antenna pole plate and the tuning plate are located in two shielded cavities. A stable electrical connection is required between the antenna pole plate and the tuning inductor on the tuning plate. Due to the limitation of the energy transmission form between the two, metal connectors of a certain size are required for connection. The metal connectors cannot be too close to the box, otherwise it will cause safety hazards.

[0084] In the related art, the tuning inductor on the tuning board will deform after long-term use, which will affect the resistance of the RF heating component, so that the output energy of the RF heating component is affected, affecting the thawing efficiency.

[0085] Based on the above technical problems, an embodiment of the present application provides a connection component for connecting the antenna plate 400 and the tuning inductor, so as to avoid deformation of the tuning inductor on the tuning plate to a certain extent, so as to ensure the thawing efficiency.

[0086] An embodiment of the present application provides a connection component suitable for connecting a tuning inductor and an antenna plate. Figure 4 shows a schematic structural diagram of a radio frequency thawing device having a connection component, Figure 5 Shows Figure 4 A top view of Figure 6 Shows Figure 4 Schematic diagram of the assembly of the connected components in . Figure 4-Figure 6 The connecting component includes a second connecting member 500 and a supporting member 600. The two ends of the second connecting member 500 are respectively connected to the tuning inductor 700 and the antenna plate 400. The supporting member 600 is arranged at the bottom end of the second connecting member 500 to support the second connecting member 500 to prevent the tuning inductor 700 from being deformed due to the deformation of the second connecting member 500.

[0087] The connection component provided in the embodiment of the present application has a support member 600 provided at the bottom of the second connection member 500 for connecting the tuning inductor 700 and the antenna plate 400. The support member 600 supports the second connection member 500, which can prevent the deformation of the tuning inductor 700 caused by the deformation of the second connection member 500 to a certain extent, thereby reducing the impact on the resistance of the RF heating component, preventing the output energy of the RF heating component from being excessively affected, ensuring the thawing efficiency, and having good practicality.

[0088] Combination Figure 4-Figure 6 The second connector 500 may be a metal plate to realize electrical connection between the antenna plate 400 and the tuning inductor 700 on the tuning board. The second connector 500 may have some bends to adapt to the connection of antenna plates 400 and the tuning inductor 700 on the tuning board at different heights. The support member 600 is made of insulating material, such as plastic, to avoid interference with the radio frequency function.

[0090] Combination Figure 7-Figure 10 , the distance between the tops of the two opposite side walls of the second positioning groove 602 of the support block 601 is greater than the distance between the bottoms, that is, the second positioning groove 602 is wide at the top and narrow at the bottom, which can facilitate the assembly of the second connecting member 500 in the second positioning groove 602. In a specific implementation, the shape of the second positioning groove 602 can be an isosceles trapezoid, of course, it can also be a right-angled trapezoid, etc., which is not limited here.

The outer peripheral surface of the buckle 1102 is arc-shaped, and a groove is provided in the middle of the buckle 1102. The grooves 603 of the plurality of buckles 1102 form a third positioning groove 1103 for clamping the second connecting member 500. In the specific implementation, the second connecting member 500 is located on the top of the second buckle 1100, so that The second snap-in hole 502 on the second connecting member 500 is opposite to the top of the second fastener 1100.

[0101] Combination Fig. 9 as well as Fig.10 A reinforcing rib 1001 may be provided between the connecting block 1000 and the supporting block 601 to enhance the reliability of the connection between the connecting block 1000 and the supporting block 601.

[0104] The RF thawing device having the above-mentioned connecting component and antenna pole plate mounting component can not only avoid the phenomenon that the antenna pole plate 400 is not parallel to the bottom surface of the corresponding box 300 during installation, thereby improving the thawing effect, but also during assembly, multiple support columns 100 can be taken and placed as a whole to improve the convenience of installing the antenna pole plate 400 and improve the assembly efficiency. It can also prevent the deformation of the tuning inductor 700 caused by the deformation of the second connecting piece 500 to a certain extent, thereby reducing the impact on the resistance of the RF heating component, so that the output energy of the RF heating component is not excessively affected, thereby ensuring the thawing efficiency and having good practicality.

[0107] In addition, there is a gap around the second connecting member 500 and the through hole 340 to avoid affecting the operation of the RF generating component and avoiding potential safety hazards.

[0108] In the related art, the tuning inductor 700 and the antenna plate 400 are arranged in a box. In actual operation, the tuning inductor 700 may affect the RF energy of the antenna plate 400. In the embodiment of the present application, the tuning inductor 700 is arranged on the outside of the box 300, and the antenna plate 400 is arranged on the inside of the box 300, so that the tuning inductor 700 and the antenna plate 400 are isolated from each other, thereby avoiding the phenomenon that the tuning inductor 700 affects the RF energy of the antenna plate 400.

The antenna plate 400 is installed in the first shielding chamber 1300 through the above-mentioned antenna plate mounting assembly. After the refrigerator drawer 1500 is pulled out, due to the shielding effect of the partition 350, not only can the user be prevented from directly seeing the antenna plate 400, but also the risk of personal injury caused by the user accidentally touching the antenna plate 400 during operation can be completely avoided, so as to improve the user experience, and also avoid the phenomenon that the antenna plate 400 is easily contaminated, so as to improve the thawing effect, which has good practicality.

[0111] In other embodiments, the first shielding cavity 1400 may also be disposed on the side or upper portion of the refrigerator drawer, etc., which is not limited here.

[0112] Combination Fig.12 as well as Fig.14 A tuning box 1200 is provided at the back of the box 300. The tuning box 1200 can be integrated at the back of the box 300. The cavity in the tuning box 1200 constitutes the above-mentioned second shielding cavity 1400. The tuning inductor 700 is arranged in the tuning box 1200 to make the first shielding cavity 1300 and the second shielding cavity 1400 independent of each other, thereby avoiding the influence of the tuning inductor 700 on the RF energy of the antenna plate 400 to a certain extent.
