Description
Technical Field
[0001] This application belongs to the field of refrigerator manufacturing technology, specifically relating to a radio frequency defrosting device and a refrigerator. Background Technology
[0002] Frozen food materials can be thawed using radio frequency (RF) heating. RF heating avoids the slow heating speed caused by traditional heating methods, which heat from the outside in and are limited by the temperature of the heat source and the thermal conductivity of the food itself. It can quickly raise the temperature of the material to the required temperature, thereby significantly improving the quality of processed food.
[0003] In related technologies, the output part of radio frequency heating is the antenna plate. The antenna plate has technical problems such as complicated assembly process and poor assembly efficiency during installation. Summary of the Invention
[0004] To address the aforementioned technical problems, this application provides a radio frequency defrosting device and a refrigerator, which to some extent solve the technical problems of complex assembly procedures and poor assembly efficiency during the installation of antenna plates.
[0005] The technical solution of this application is as follows:
[0006] On one hand, this application provides a radio frequency defrosting device, which includes: a housing; an antenna electrode plate, and multiple spaced support columns disposed in the housing, the bottom of each support column being connected to the bottom of the housing, the antenna electrode plate being supported on the top of the multiple support columns, and one support column being connected to at least one adjacent support column through a first connector so that the multiple support columns form an integral structure.
[0007] The radio frequency defrosting device provided in this application can install the antenna electrode plate on the bottom surface of the corresponding housing through multiple support columns. Since one support column and at least one adjacent support column are connected by a first connector, the multiple support columns can form an integral structure to ensure the consistency of the support columns. This avoids the phenomenon that the antenna electrode plate is not parallel to the bottom surface of the corresponding housing during installation, thus improving the defrosting effect. Moreover, during assembly, the multiple support columns can be picked up and put down as a whole, thereby improving the convenience of antenna electrode plate installation and improving assembly efficiency.
[0008] In some implementations, the first connector is elastic to accommodate the pulling and tilting between the support columns caused by dimensional assembly errors, thereby further improving the parallelism between the antenna plate and the corresponding bottom surface of the housing and enhancing the defrosting effect.
[0009] In some implementations, the first connector is curved.
[0010] In some implementations, the bottom end of the support column is provided with multiple fins spaced circumferentially, and each fin is connected to a positioning member on its outer side. The bottom end of the positioning member protrudes from the bottom end of the support column and is inserted into the bottom of the housing. In this way, the antenna electrode mounting assembly can be initially positioned by inserting the positioning member into the bottom surface of the corresponding housing.
[0011] In some implementations, the first connector and the connected support column are connected via the fins and the positioning element.
[0012] In some implementations, the top of the support column is provided with a plurality of first fastening members spaced axially around the support column. The outer peripheral surface of the first fastening member is arc-shaped, and the middle part of the first fastening member is provided with a groove. The grooves of the plurality of first fastening members form a first positioning groove for locking the antenna electrode plate. The antenna electrode plate is engaged in the first positioning groove to realize the assembly of the antenna electrode plate on the support column.
[0013] In some embodiments, a first guide slope is provided at the top of the outer peripheral surface of the first buckle, and the top of the first guide slope extends in the axial direction of the support column.
[0014] In some implementations, three support columns are provided, arranged in a triangle, and adjacent support columns are connected by the first connector.
[0015] In some embodiments, the radio frequency defrosting device further includes: a tuning inductor disposed on the outside of the housing; a second connector passing through the side wall of the housing, the two ends of the second connector being connected to the tuning inductor and the antenna plate, respectively; and a support member disposed at the bottom end of the second connector to support the second connector.
[0016] Because the bottom of the second connector used to connect the tuning inductor and the antenna plate is provided with a support, which supports the connector, it can prevent the tuning inductor from deforming due to the deformation of the connector 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 affected too much, ensuring the defrosting efficiency, and has good practicality.
[0017] The support includes a support block with a second positioning groove on the top. The second connector is fitted into the second positioning groove of the support block. The second positioning groove prevents the connector from moving along its width direction, thereby avoiding deformation of the connector in its width.
[0018] In some implementations, a second positioning post is provided at the bottom of the positioning groove, and the second connector is provided with a second positioning hole that cooperates with the support post, with the second positioning post placed in the second positioning hole.
[0019] In some embodiments, the second positioning post includes: a body connected to the bottom of the second positioning groove; a plurality of ribs spaced apart on the circumferential surface of the body, the plurality of ribs being disposed in the positioning hole in cooperation, and a second guide slope being provided on the top of the outer side of the ribs, the second guide slope extending obliquely from bottom to top in the axial direction of the positioning post.
[0020] In some embodiments, the support further includes: a connecting block disposed on the side of the support block; and a second fastener disposed on the connecting block, wherein the second connecting block has a second snap-fit hole that mates with the second snap-fit hole, and the second snap-fit hole is disposed in the second snap-fit hole.
[0021] In some embodiments, the second fastening member includes: a connecting post connected to the connecting block, the top of the connecting post being provided with a plurality of fasteners spaced circumferentially around the fastening post, the outer peripheral surface of the fasteners being arc-shaped, the middle part of the fasteners being provided with a groove, the grooves of the plurality of fasteners forming a third positioning groove for locking the second connecting member, the second connecting member being engaged in the third positioning groove.
[0022] In some embodiments, a third guide ramp is provided at the top of the outer peripheral surface of the fastener, the third guide ramp extending obliquely from bottom to top in the axial direction of the connecting post.
[0023] In some embodiments, the side wall of the enclosure is provided with a through hole, the support member is disposed in the through hole, and the two ends of the second connector are respectively located on the outer and inner sides of the enclosure to be connected to the tuning inductor and the antenna plate, respectively.
[0024] In some embodiments, the second connector and the periphery of the through hole have a gap. A first shielding cavity is provided inside the housing, and the antenna electrode is disposed within the first shielding cavity; a second shielding cavity is provided outside the housing, and the tuning inductor is disposed within the second shielding cavity, the second shielding cavity being integrated into the housing.
[0025] On the other hand, this application also provides a refrigerator that includes the above-mentioned radio frequency defrosting device.
[0026] Refrigerators equipped with the aforementioned radio frequency defrosting device not only prevent the antenna plate from being misaligned with the bottom surface of the corresponding cabinet during installation, thus improving the defrosting effect, but also allow multiple support columns to be used as a whole during assembly, improving the convenience of antenna plate installation and increasing assembly efficiency. Furthermore, it can, to some extent, prevent the deformation of the tuning inductor caused by the deformation of the connectors, thereby reducing the impact on the resistance of the radio frequency heating component and ensuring that the output energy of the radio frequency heating component is not excessively affected, thus guaranteeing defrosting efficiency. It has excellent practicality. Attached Figure Description

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0060] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0061] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0062] This application is described below with reference to the accompanying drawings and specific embodiments:
[0063] In related technologies, the antenna electrode is fixedly assembled to the bottom of the corresponding housing using multiple spaced-apart support columns. The purpose of using multiple support columns is to ensure the parallelism between the antenna electrode and the bottom of the housing. However, since the multiple support columns are independent of each other, during multiple batches of production and supply, it is possible that three support columns from different batches may be used to fix and support a single antenna electrode. Because the dimensions of the support columns may be inconsistent, this can ultimately cause the antenna electrode to be non-parallel to the bottom of the housing, affecting the defrosting effect. Furthermore, if multiple support columns are directly connected together, dimensional errors during assembly may cause the support columns to pull and tilt against each other, affecting not only the efficiency of antenna assembly but also the parallelism between the antenna electrode and the bottom surface of the housing.
[0064] Based on the above-mentioned technical problems, the applicant designed an antenna pole plate mounting assembly to solve, to some extent, the technical problems of complex assembly process and poor assembly efficiency during antenna pole plate installation, and also to ensure the parallelism between the antenna pole plate and the bottom surface of the corresponding housing.
[0065] Figure 1 Schematic diagrams of antenna electrode mounting assemblies in some embodiments are shown. (Combined with...) Figure 1 This application provides an antenna pole mounting assembly, which includes a support column 100 and a first connector 200. Multiple support columns 100 are spaced apart, and a support column 100 and at least one adjacent support column 100 are connected by the first connector 200 so that the multiple support columns 100 form an integral structure.
[0066] Figure 2 It shows the antenna plates passing through Figure 1 The diagram shows the installation of the antenna electrode mounting assembly. Figure 3 It shows Figure 2 A schematic diagram of the explosion. Combined with... Figures 2-3 The antenna electrode mounting assembly provided in this application embodiment allows the antenna electrode 400 to be mounted on the bottom surface of the corresponding housing 300 via multiple support columns 100. Since a support column 100 and at least one adjacent support column 100 are connected by a first connector 200, the multiple support columns 100 can form an integral structure, ensuring the consistency of the support columns 100. This avoids the phenomenon that the antenna electrode 400 is not parallel to the bottom surface of the corresponding housing 300 during installation, improving the defrosting effect. Furthermore, during assembly, the multiple support columns 100 can be picked up and used as a whole, improving the convenience of antenna electrode 400 installation and increasing assembly efficiency.
[0067] Combination Figures 1-3 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 connector 200, that is, three first connectors 200 are also provided. The three support columns 100 are connected into an integral structure by the three first connectors 200. When assembling the antenna plate 400, the integral structure can be placed 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 other means.
[0068] In some embodiments, the first connector 200 is elastic. During assembly, if there is a dimensional error that causes the support columns 100 to pull and tilt against each other, the elastic first connector 200 will deform accordingly to accommodate the pulling and tilting of the support columns 100 caused by the dimensional assembly error, so that the support columns 100 are kept as vertical as possible, thereby improving the parallelism between the antenna plate 400 and the bottom surface of the corresponding housing 300 and improving the defrosting effect.
[0069] In some embodiments, the first connector 200 is preferably made of 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 between the support columns 100 caused by the dimensional assembly error, so that the support columns 100 are kept as vertical as possible, thereby improving the parallelism between the antenna plate 400 and the bottom surface of the corresponding housing 300 and improving the defrosting effect.
[0070] In some embodiments, the first connector 200 may be wavy ( Figure 1 (as shown), arc-shaped and / or sawtooth-shaped. That is, the first connector 200 can be only wavy, arc-shaped or sawtooth-shaped, or any combination of two or three, without limitation.
[0071] It should be noted that, since the turning point of the wavy or arc-shaped first connector 200 is transitioned by a curve, while the turning point of the sawtooth-shaped first connector 200 is transitioned by a straight line, in practice, the first connector 200 with a curve transition is less likely to break than the first connector 200 with a straight transition, which can improve the product assembly yield and thus improve the assembly effect.
[0072] Combination Figures 2-3 During implementation, bolt holes can be provided at the bottom end of the support column 100, and connection holes 310 can be provided on the bottom surface of the corresponding housing 300. In this way, the support column 100 can be fixed to the bottom surface of the corresponding housing 300 by means of screw connection. If the antenna pole plate 200 is not installed horizontally, the screws can be finely adjusted until the antenna pole plate 200 is horizontal.
[0073] Combination Figure 1In some embodiments, the bottom end of the support column 100 may be provided with a plurality of fins 110 at intervals along the circumference. Each fin 110 is connected to a positioning member 120 on its outer side. 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 inserted into the positioning hole on the bottom surface of the corresponding housing 300 to achieve the initial positioning of the antenna electrode mounting assembly. Then, the support column 100 may be fixed to the bottom surface of the corresponding housing 300 by means of screw assembly.
[0074] Combination Figures 1-3 In some embodiments, the positioning member 120 may include a first positioning post 121 and a positioning boss 122. The first positioning post 121 is connected to the outside of the fin 110, and the positioning boss 122 is connected to the bottom end of the first positioning post 121. The positioning boss 122 protrudes from the bottom end of the support post 100. In practice, the bottom surface of the housing 300 is provided with a positioning hole 320. By inserting the positioning boss 122 into the positioning hole 320 on the bottom surface of the corresponding housing 300, the initial positioning of the antenna electrode mounting assembly can be achieved.
[0075] Combination Figure 1 In some embodiments, the positioning boss 122 may be frustoconical, with the bottom diameter of the positioning boss 122 being smaller than the top diameter of the positioning boss 122, i.e., the positioning boss 122 is an inverted frustoconical shape, so that the positioning boss 122 can be quickly inserted into the positioning hole on the bottom surface of the corresponding housing 300.
[0076] In other embodiments, the positioning boss 122 may also be wedge-shaped or conical, etc., and there is no limitation here.
[0077] In some embodiments, the bottom end of the first positioning post 121 is preferably on the same plane as the bottom end of the support post 100. After the first positioning post 121 is assembled in place, the bottom end of the first positioning post 121 and the bottom end of the support post 100 can be checked to determine whether the bottom end of the first positioning post 121 and the bottom end of the support post 100 are on the same plane, thereby maintaining the perpendicularity of the support post 100 to the bottom of the corresponding housing 300 and further improving the parallelism between the antenna pole plate 400 and the bottom surface of the corresponding housing 300.
[0078] In some embodiments, the first connector 200 and the connected support column 100 are connected by 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 plate mounting assembly is preferably integrally formed to ensure the integrity of the whole device.
[0079] In other embodiments, the first connector 200 may also be directly formed on the circumferential surface of the connected support column 100, without limitation.
[0080] Combination Figure 1 In some embodiments, the top of the support column 100 is provided with a plurality of first fastening members 130 spaced apart axially around the support column 100. The outer peripheral surface of the first fastening member 130 is arc-shaped, and the middle part of the first fastening member 130 is provided with a groove. The grooves of the plurality of first fastening members 130 form a first positioning groove 132 for locking the antenna electrode plate 400, and the antenna electrode plate 400 is locked in the first positioning groove 132. In practical implementation, the antenna electrode plate 400 is provided with a first snap-fit hole 401 corresponding to the support column 100. The antenna electrode plate 400 is placed on the top of the multiple support columns 100, so that the top of the support column 100 faces the corresponding first snap-fit hole 401 on the antenna electrode plate 400. When the antenna electrode plate 400 is pressed down, the multiple first snap fasteners 130 at the top of the support column 100 retract inward, and the antenna electrode plate 400 is inserted into the groove from the top of the first snap fastener 130. Subsequently, the multiple snap fasteners 130 at the top of the support column 100 are reset, which can prevent the antenna electrode plate 400 from falling off the snap fasteners 130 and improve the stability of the antenna electrode plate 400 after assembly.
[0081] Combination Figure 1 In some embodiments, the top of a support column 100 may be provided with four first fasteners 130, which form a ring. The diameter of the ring may be the same as the diameter of the support column 100. The top of the outer peripheral surface of the first fastener 130 may be provided with a first guide slope 131, which extends in the axial direction of the support column 100. This can provide guidance for the assembly of the antenna electrode 400 on the first fastener 130.
[0082] The antenna plate mounting assembly provided in this application uses a first connector 200 to fix multiple 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 pulling and tilting to each other, making assembly more convenient.
[0083] In addition, the antenna plate and the tuning plate are two important components required for radio frequency heating. The antenna plate and the tuning plate are located in two shielded cavities. A stable electrical connection is required between the tuning inductors on the antenna plate and the tuning plate. Due to the limitation of the energy transmission form between the two, a metal connector of a certain size must be used for connection. The metal connector should not be too close to the enclosure, otherwise it will cause safety hazards.
[0084] In related technologies, the tuning inductor on the tuning board will deform after long-term use, which will affect the resistance of the radio frequency heating component, thus affecting the output energy of the radio frequency heating component and the defrosting efficiency.
[0085] Based on the above-mentioned technical problems, this 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, thereby ensuring the defrosting efficiency.
[0086] This application provides a connection component suitable for connecting a tuning inductor and an antenna plate. Figure 4 A schematic diagram of a radio frequency defrosting device with connecting components is shown. Figure 5 It shows Figure 4 A top-down view. Figure 6 It shows Figure 4 An assembly diagram of the connecting components. (Combined with...) Figures 4-6 The connection assembly includes a second connector 500 and a support 600. The two ends of the second connector 500 are connected to the tuning inductor 700 and the antenna plate 400, respectively. The support 600 is disposed at the bottom of the second connector 500 to support the second connector 500 and prevent the tuning inductor 700 from deforming due to the deformation of the second connector 500.
[0087] The connection assembly provided in this application embodiment has a support member 600 at the bottom of the second connector 500 used to connect the tuning inductor 700 and the antenna electrode 400. The support member 600 supports the second connector 500 and can prevent the tuning inductor 700 from deforming due to the deformation of the second connector 500 to a certain extent. This reduces the impact on the resistance of the radio frequency heating assembly, so that the output energy of the radio frequency heating assembly is not affected too much, ensuring the defrosting efficiency. It has good practicality.
[0088] Combination Figures 4-6 The second connector 500 can be a metal plate to achieve electrical connection between the antenna electrode 400 and the tuning inductor 700 on the tuning board. The second connector 500 may have some bends to accommodate connections between the antenna electrode 400 and the tuning inductor 700 on the tuning board at different heights. The support member 600 is made of an insulating material, such as plastic, to avoid interference with radio frequency functions.
[0089] To improve the support stability of the second connector 500 to the tuning inductor 700, the embodiments of this application further improve the above-mentioned connection components. Figure 7 A schematic diagram of the connecting component is shown. Figure 8 It shows Figure 7 A structural diagram of the connector. Figure 9 It shows Figure 8A schematic diagram of the support block in the diagram. Figure 10 It shows Figure 9 A structural diagram from another perspective. Combined with... Figures 7-10 The support member 600 may include a support block 601, the top of which is provided with a second positioning groove 602, and the second connector 500 is fitted into the second positioning groove 602 of the support block 601. The second positioning groove 602 prevents the second connector 500 from moving along its width direction, thereby avoiding deformation of the second connector 500 in its width.
[0090] Combination Figures 7-10 The distance between the tops of the two opposite sidewalls of the second positioning groove 602 of the support block 601 is greater than the distance between their bottoms, meaning the second positioning groove 602 has a shape that is wider at the top and narrower at the bottom. This facilitates the assembly of the second connector 500 within the second positioning groove 602. In specific implementations, the shape of the second positioning groove 602 can be an isosceles trapezoid, or it can be a right trapezoid, etc., without any limitation.
[0091] Combination Figures 7-10 The bottom of the second positioning groove 602 may be provided with a second positioning post 800, and the second connecting member 500 is provided with a second positioning hole 501 that cooperates with the second positioning post 800. The second positioning post 800 is placed in the second positioning hole 501 to further position the second connecting member 500 and further prevent the second connecting member 500 from deforming and moving.
[0092] Combination Figure 9 as well as Figure 10 The second positioning post 800 may include a body 801 and a plurality of ribs 802. The body 801 is connected to the bottom of the second positioning groove 602. The plurality of ribs 802 are spaced apart on the circumferential surface of the body 801. The plurality of ribs 802 are cooperated in the second positioning hole 501 to position the second connector 500.
[0093] Combination Figure 9 as well as Figure 10 Each rib 802 has a second guide slope 803 on the top of its outer side. The second guide slope 803 extends obliquely from bottom to top toward the second positioning post 800. The second guide slope 803 is provided to facilitate the assembly of the second connector 500 on the second positioning post 800.
[0094] Combination Figure 9 as well as Figure 10A clearance groove 603 may be provided on the support block 601. The clearance groove 603 extends along the setting direction of the second connector 500. A U-shaped plate 900 may be provided on the side of the support block 601 facing the antenna plate 400. The U-shaped plate 900 may be integrally formed with the support block 601. The two side plates 901 of the U-shaped plate 900 are connected to the two sides of the clearance groove 603. The bottom plate 902 of the U-shaped plate 900 is parallel to the support block 601. The bottom plate 902 of the U-shaped plate 900 and the bottom of the clearance groove 603 are connected by a transition plate. The two sides of the transition plate are also connected to the two side plates 901 of the U-shaped plate 900. The second positioning groove 602 of the support block 601 may be opened on the top of the bottom plate 902 of the U-shaped plate 900.
[0095] Combination Figure 9 as well as Figure 10 In the case of the U-shaped plate 900, four ribs 802 can be equally spaced around the circumference of the body 801. Two of the ribs 802 are shorter and the other two are longer. The bottom ends of the two shorter ribs 802 are connected to the top of the bottom plate 902 of the U-shaped plate 900, and the two longer ribs 802 can extend from the body 801 to both sides of the bottom plate 902 of the U-shaped plate 900.
[0096] In other embodiments, the second positioning groove 602 of the support block 601 can also be directly disposed on the support block 601, and there is no limitation on this.
[0097] Combination Figures 7-10 The connecting assembly may further include a connecting block 1000 and a second fastener 1100. The connecting block 1000 is disposed on the side of the support block 601, and the second fastener 1100 is disposed on the connecting block 1000. The second connecting member 500 is provided with a second snap-fit hole 502 that cooperates with the second fastener 1100. The second fastener 1100 is disposed in the second snap-fit hole 502 to further position the second connecting member 500 and further prevent the second connecting member 500 from deforming or moving.
[0098] Combination Figure 9 as well as Figure 10 When the U-shaped plate 900 is present, the connecting block 1000 can be positioned on the side of the support block 601 facing away from the U-shaped plate 900. This allows for better support of the second connecting member 500 by increasing the distance between the second latching member 1100 and the second positioning post 800 on the connecting block 1000, preventing deformation of the second connecting member 500. Furthermore, the connecting block 1000's placement on the side of the support block 601 facing the tuning inductor 700 further supports the tuning inductor 700 and prevents deformation.
[0099] Combination Figure 9 as well as Figure 10The second fastening member 1100 includes a connecting post 1101 and fasteners 1102. The connecting post 1101 is connected to the connecting block 1000. Multiple fasteners 1102 are circumferentially spaced around the top of the connecting post 1101. The outer circumferential surface of each fastener 1102 is arc-shaped, and a groove is provided in the middle of each fastener 1102. The grooves 603 of the multiple fasteners 1102 form a third positioning groove 1103 for securing the second connecting member 500. In specific implementation, the second connecting member 500 is placed on top of the second fastening member 1100, so that... The second snap-fit hole 502 on the second connector 500 is directly opposite the top of the second snap fastener 1100. When the second connector 500 is pressed down, the multiple snaps 1102 on the second snap fastener 1100 retract inward, and the second connector 500 is inserted from the top of the multiple snaps 1102 into the third positioning groove 1103. Subsequently, the multiple second snap fasteners 1100 are reset to prevent the second connector 500 from falling off the second snap fastener 1100, thereby improving the stability of the second connector 500 after assembly and limiting the movement of the second connector 500 in the height direction.
[0100] Combination Figure 9 as well as Figure 10 The second fastener 1100 may be provided with four equally spaced fasteners 1102, which form a ring. The top of the outer peripheral surface of each fastener 1102 may be provided with a third guide slope 1104. The third guide slope 1104 extends obliquely from bottom to top towards the axial direction of the connecting post 1101, so as to provide guidance for the assembly of the second connector 500 on the second fastener 1100.
[0101] Combination Figure 9 as well as Figure 10 A reinforcing rib 1001 may be provided between the connecting block 1000 and the support block 601 to enhance the reliability of the connection between the connecting block 1000 and the support block 601. Two reinforcing ribs 1001 may be provided, which may be provided on both sides of the connecting block 1000 in the width direction, and the two reinforcing ribs 1001 are respectively connected to the side of the support block 601.
[0102] It should be noted that the support block 601 and the connecting block 1000 constituting the connecting assembly are preferably integrally formed to facilitate processing and manufacturing.
[0103] On the other hand, based on the aforementioned connecting components, embodiments of this application also provide a radio frequency defrosting device. (Combined with...) Figures 4-6The radio frequency defrosting device includes a housing 300, a tuning inductor 700, an antenna electrode 400, the aforementioned connecting assembly, and the aforementioned antenna electrode mounting assembly. The tuning inductor 700 is disposed on the outer side of the housing 300, the antenna electrode 400 is disposed on the inner side of the housing 300, the side wall of the housing 300 is provided with a through hole 340, the support member 600 is disposed in the through hole 340, the two ends of the second connecting member 500 are respectively located on the outer side and the inner side of the housing 300, so as to be connected to the tuning inductor 700 and the antenna electrode 400 respectively, and the antenna electrode 400 is disposed in the housing 300 through the aforementioned antenna electrode mounting assembly.
[0104] The radio frequency defrosting device with the aforementioned connecting components and antenna electrode mounting components not only avoids the phenomenon that the antenna electrode 400 is not parallel to the bottom surface of the corresponding housing 300 during installation, thus improving the defrosting effect, but also allows multiple support columns 100 to be picked up and placed as a whole during assembly, improving the ease of installation of the antenna electrode 400 and increasing assembly efficiency. It can also, to a certain extent, prevent the deformation of the tuning inductor 700 caused by the deformation of the second connecting piece 500, thereby reducing the impact on the resistance of the radio frequency heating component, ensuring that the output energy of the radio frequency heating component is not excessively affected, and guaranteeing defrosting efficiency. It has excellent practicality.
[0105] Combination Figures 4-6 In specific implementation, the tuning inductor 700 and the antenna plate 400 can be respectively set on both sides of the back plate 330 of the housing 300, and the second connector 500 can be connected to the bottom of the tuning inductor 700. This can better support the tuning inductor 700 and more comprehensively prevent the tuning inductor 700 from deforming.
[0106] Figure 11 An assembly diagram of the connectors and tuning inductor is shown. (Combined with...) Figure 8 as well as Figure 11 The second connector 500 may have a connecting flange 503 at one end facing the tuning inductor 700, which can be connected to the tuning inductor 700 by screws. Figure 1 as well as Figure 2 The end of the second connector 500 facing the antenna plate 400 can be directly connected to the antenna plate 400 by screws. The support block 601 of the support member 600 can be assembled on the back plate 330 by bolt connection, which will not be described in detail here.
[0107] In addition, the second connector 500 and the periphery of the through hole 340 have gaps to avoid affecting the operation of the radio frequency generation component and to avoid safety hazards.
[0108] In related technologies, the tuning inductor 700 and the antenna plate 400 are housed within a single enclosure. During actual operation, the tuning inductor 700 may affect the radio frequency (RF) energy of the antenna plate 400. However, in this embodiment, the tuning inductor 700 is located on the outside of the enclosure 300, while the antenna plate 400 is located on the inside of the enclosure 300. This isolates the tuning inductor 700 from the antenna plate 400, thus preventing the tuning inductor 700 from affecting the RF energy of the antenna plate 400.
[0109] Figure 12 A schematic diagram of a radio frequency defrosting device with two shielded cavities is shown. Figure 13 It shows Figure 12 A top-down view. Figure 14 It shows Figure 13 A schematic diagram of the AA cross-section. Combined with... Figures 12-14 In actual implementation, a first shielding cavity 1300 can be provided inside the housing 300 for mounting the antenna electrode plate 400, and a second shielding cavity 1400 can be provided outside the housing 300 for mounting the tuning inductor 700. The second shielding cavity 1400 can be integrated on the outside of the housing 300 for easy installation.
[0110] Combination Figure 12 A partition 350 can be horizontally arranged inside the cabinet 300, dividing the cabinet 300 into a first chamber located above and a second chamber located below. The first chamber is used to accommodate the refrigerator drawer 1500, and the second chamber can be defined as a first shielding cavity 1300. The antenna electrode 400 is installed in the first shielding cavity 1300 via the aforementioned antenna electrode mounting assembly. After the refrigerator drawer 1500 is pulled out, the partition 350 not only prevents the user from directly seeing the antenna electrode 400, but also completely avoids the risk of personal injury caused by accidental contact with the antenna electrode 400 during operation, thus improving the user experience. It also prevents the antenna electrode 400 from being easily contaminated, thereby improving the defrosting effect, demonstrating excellent practicality.
[0111] In other embodiments, the first shielding cavity 1400 may also be located on the side or top of the refrigerator drawer, etc., without limitation.
[0112] Combination Figure 12 as well as Figure 14 A tuning enclosure 1200 is provided on the back of the enclosure 300. The tuning enclosure 1200 can be integrated into the back of the enclosure 300. The cavity inside the tuning enclosure 1200 constitutes the second shielding cavity 1400 mentioned above. The tuning inductor 700 is disposed inside the tuning enclosure 1200 so that the first shielding cavity 1300 and the second shielding cavity 1400 are independent of each other, thereby avoiding the influence of the tuning inductor 700 on the radio frequency energy of the antenna plate 400 to a certain extent.

[0114] The refrigerator equipped with the aforementioned radio frequency defrosting device not only avoids the phenomenon that the antenna plate 400 is not parallel to the bottom surface of the corresponding cabinet 300 during installation, thus improving the defrosting effect, but also allows multiple support columns 100 to be used as a whole during assembly, improving the ease of installation of the antenna plate 400 and increasing assembly efficiency. It can also, to a certain extent, prevent the deformation of the tuning inductor 700 caused by the deformation of the second connector 500, thereby reducing the impact on the resistance of the radio frequency heating component and ensuring that the output energy of the radio frequency heating component is not excessively affected, thus guaranteeing defrosting efficiency. It has excellent practicality.
