Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to a power input connector, a radio frequency defrosting device, and a refrigeration equipment. Background Technology

[0002] As user demand for refrigeration equipment such as refrigerators increases, the functionality of these devices is also constantly expanding. For example, to meet users' needs for rapid defrosting of frozen food inside the refrigeration equipment, radio frequency (RF) defrosting devices are being installed to quickly defrost frozen food in the refrigerator.

[0003] In related technologies, radio frequency defrosting devices generate radiation during operation. The enclosure of the radio frequency defrosting device is the main component for suppressing radiation leakage. The antenna plate located inside the enclosure needs to be connected to the power amplifier on the outside of the substrate via a cable, and a feed inlet needs to be opened on the enclosure. However, due to the large size of the feed inlet, radiation leakage is easily caused, affecting the integrity of signal transmission and radiation suppression performance. Summary of the Invention

[0004] This application provides a power input connector, an RF defrosting device, and a cooling device, aiming to at least partially solve the technical problem that a large feed inlet size easily causes radiation leakage, affecting the integrity of signal transmission and radiation suppression performance.

[0005] In a first aspect of this application, a power input connector is provided, which is assembled into the housing of an RF defrosting device. The housing has a feed inlet, and an antenna plate is disposed inside the housing. The power input connector includes: a feed pin that passes through the feed inlet and is connected to the antenna plate; a support base that connects to the feed pin and has a sealing protrusion; and a clamping member that is arranged opposite to the support base and is connected to the sealing protrusion. When the feed pin passes through the feed inlet, the clamping member and the support base are arranged opposite to each other on both sides of the side wall of the housing, and the sealing protrusion is adapted to pass through the feed inlet.

[0006] The power input connector provided in this application can seal the feed inlet because the size of the support base and clamping parts are larger than the feed inlet, thereby preventing radiation leakage to a certain extent and ensuring the integrity of signal transmission and radiation suppression performance.

[0007] In some embodiments, the clamping member abuts against the inner side of the side wall of the housing, and the support abuts against the outer side of the side wall of the housing.

[0008] In some implementations, the clamp is threadedly connected to the sealing protrusion.

[0009] In some embodiments, the power input connector further includes a seal disposed between the support and the clamp.

[0010] In some embodiments, the power input connector further includes a connector that connects to the feed pin; wherein, when the feed pin passes through the antenna plate, the connector abuts against the side of the antenna plate facing away from the support.

[0011] In some embodiments, the feed pin is provided with a limiting member, the clamping member is disposed between the limiting member and the support base, and the limiting member is disposed between the clamping member and the connecting member; wherein, when the feed pin passes through the antenna plate, the limiting member and the connecting member abut against both sides of the antenna plate.

[0012] In some implementations, the limiting member is integrally connected to the feed needle, the outer ring size of the limiting member is smaller than the feed inlet, and the connector is threadedly connected to the feed needle.

[0013] In a second aspect, this application also provides a radio frequency defrosting device, the radio frequency defrosting device comprising: a housing, wherein a feed inlet is provided on the side wall of the housing; the aforementioned feed input connector; wherein the feed needle passes through the feed inlet, and the clamping member and the support base abut against the two sides of the side wall of the housing.

[0014] In some embodiments, the side wall of the housing is provided with a second recess, and the bottom of the second recess has the feed inlet.

[0015] In a third aspect, this application also provides a refrigeration device, which includes the above-described radio frequency defrosting device.

[0016] The refrigeration equipment and radio frequency defrosting device provided in this application can prevent radiation leakage from the enclosure to a certain extent, and ensure the integrity of signal transmission and radiation suppression performance. Attached Figure Description

[0042] To enable those skilled in the art to more clearly understand this application, the technical solutions in 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.

[0043] As user demand for refrigeration equipment such as refrigerators increases, the functionality of these devices is also constantly expanding. For example, to meet users' needs for rapid defrosting of frozen food inside the refrigeration equipment, radio frequency (RF) defrosting devices are being installed to quickly defrost frozen food in the refrigerator.

[0044] Figure 1 A schematic diagram of the radio frequency defrosting device 1 is shown. (Combined with...) Figure 1A radio frequency (RF) defrosting device 1 is installed inside a refrigeration unit to rapidly defrost frozen food within the unit, thus meeting the multi-functional requirements of the refrigeration equipment. The RF defrosting device 1 includes a base 10, a housing 20, a drawer 30, and a power amplifier 40. The housing 20 and the power amplifier 40 are both mounted on the base 10. The front of the housing 20 is open, and the drawer 30 is slidably connected to the housing 20. The power amplifier 40 is located at the rear of the housing 20 and is connected to an antenna plate (not shown) inside the housing 20. The antenna plate radiates radio frequency energy into the housing 20 to defrost items in the drawer 30.

[0045] Radio frequency defrosting devices 1 mostly employ microwave heating technology. The most commonly used frequency for microwave heating is 2.45 GHz, which is an exempt frequency for engineering, science and medicine, and does not have requirements for EMC (electromagnetic compatibility) radiated interference. However, if other non-exempt frequency bands are used as the main power, it poses a great challenge to EMC radiation suppression.

[0046] In related technologies, in order to solve the radiation suppression of EMC, the enclosure 20 of the radio frequency defrosting device 1 is mostly a metal enclosure. However, the metal enclosure is assembled from multiple separate sheet metal parts by riveting or pressing. Although good conductivity is ensured at the connection points of the separate sheet metal parts, the discontinuous conductivity at the gaps between the separate sheet metal parts will still cause large radiation leakage.

[0047] Based on the above-mentioned technical problems, this application provides a radio frequency defrosting box 20, a radio frequency defrosting device 1, and a refrigeration device. The base of the radio frequency defrosting box 20 is made by pressing a sheet metal part, and there is only one connection part. The connection part can be formed by welding, which can ensure the continuity of conductivity at the connection point, thereby solving the risk of large radiation leakage of the box 20 to at least a certain extent.

[0048] The radio frequency defrosting chamber 20 includes a base 200, which includes a shielding plate 204. The shielding plate 204 is bent to form a through cavity 203. The shielding plate 204 is connected to two sides along the through direction of the cavity 203. A back plate 201 is connected to the base 200. The back plate 201 is used to seal one end of the cavity 203 in the through direction. The other end of the cavity 203 in the through direction forms a loading and unloading port.

[0049] Based on this design concept and in conjunction with the accompanying drawings, the specific details of the radio frequency defrosting chamber 20 are further described.

[0050] Figure 2 A schematic diagram of the structure of the radio frequency defrosting chamber 20 in one or more embodiments of this application is shown. Figure 3 It shows Figure 2A schematic diagram of the explosion. Combined with... Figure 2 as well as Figure 3 The radio frequency defrosting box 20 includes a base 200, a back plate 201, and a baffle 202. The base 200 is provided with a through-hole receiving cavity 203. The back plate 201 is connected to the back of the base 200 and seals the back of the receiving cavity 203 so that the base 200 and the back plate 201 form a storage chamber with a front opening. The baffle 202 is connected to the base 200 and is located at the outer edge of the front opening of the receiving cavity 203 to block the door 300 of the drawer 30 that is used in conjunction with the box 20.

[0051] Figure 4 It shows Figure 2 A schematic diagram of the structure of the substrate 200. (Combined with...) Figure 4 The difference between this application and related technologies is that the substrate 200 of this application includes a shielding plate 204, which is bent to form a through cavity 203. That is, the substrate 200 of this application only includes one shielding plate 204, and the shielding plate 204 has only one connecting part after bending. Compared with the assembly method of the substrate 200 in related technologies, which has four connecting parts through the assembly of multiple separate sheet metal parts, this application has only one connecting part, which reduces the risk of radiation leakage.

[0052] Furthermore, after the shielding plate 204 of this application is bent, it has two sides along the through direction of the receiving cavity 203. In one embodiment, the two sides are connected by welding, that is, the connecting part of the shielding plate 204 is formed by welding, for example by continuous laser welding, to ensure the continuity of conductivity at the connection and to reduce the risk of radiation leakage to a certain extent. In another embodiment, the two sides can also be connected by bonding and / or riveting, and this application does not limit this.

[0053] In some embodiments, the shielding plate 204 is a metal plate, such as stainless steel, which can ensure rust prevention and good conductivity without coating. In another embodiment, an anti-rust layer can be coated on the inner and outer surfaces of the shielding plate 204 to improve conductivity.

[0054] In some embodiments, the thickness of the shielding plate 204 can be greater than 0.5 mm, for example 0.7 mm or 0.9 mm, so as to have good radiation shielding capability while having sufficient strength for use.

[0055] In some embodiments, the shielding plate 204 can be formed with protruding structures 205 by processes such as stamping. For example, protruding structures 205 extending outward from the base 200 are provided on both side walls in the width direction of the base 200, with two protruding structures 205 on each side wall in the width direction of the base 200. This not only increases the strength of the base 200 itself, but also provides installation space for the slides for opening and closing the drawer 30, which has good practicality. Of course, protruding structures 205 can also be provided on the bottom of the base 200, and this application does not limit this.

[0056] Combination Figure 3 as well as Figure 4 The base 200 has a first recess 206 on its side wall for mounting the antenna electrode 50. Specifically, the first recess 206 is located on the bottom side wall of the base 200. The bottom of the base 200 is connected to a support column 207. There can be two support columns 207 arranged opposite each other. The two support columns 207 can be integrally formed with the base 200. The antenna electrode 50 is connected to the two support columns 207. The first recess 206 at the bottom of the base 200 can be covered by a cover plate on the antenna cover plate 50 to make the bottom of the base 200 form a flat surface, which is convenient for placing the drawer 30 or directly placing food to be thawed.

[0057] Figure 5 It shows Figure 2 A structural diagram from the rear view. Combined with... Figure 5 The backplate 201 and the receiving cavity 203 are connected by continuous welding. In some embodiments, the backplate 201 is also a single piece of metal plate. The backplate 201 is welded to the inside of the base 200 by a continuous welding process to seal the back of the receiving cavity 203 and reduce radiation leakage. There is a certain gap between the backplate 201 and the back of the base 200 so that the back is recessed into the back of the base 200, providing sufficient welding area between the backplate 201 and the base 200 and improving the ability to shield radiation leakage. In another embodiment, one side of the backplate 201 is integrally formed with the shielding plate 204, and the remaining side of the backplate 201 is welded to the inside of the base 200 by a welding process. This arrangement reduces the connection portion formed by the connection between the backplate 201 and the base 200, further reducing radiation leakage.

[0058] Figure 6 It shows Figure 2 A structural diagram from the front view. Combined with... Figure 6The retaining frame 202 is a one-piece molded structure, connected to the outer edge of the access opening. In some embodiments, the retaining frame 202 is also a one-piece molded structure, connected to the front side of the base 200, and connected to the outer edge of the front opening of the receiving cavity 203. When the drawer 30 is closed in the box 20, the door 300 of the drawer 30 abuts against the retaining frame 202 to prevent radiation leakage.

[0059] Combination Figure 6 The baffle 202 is a frame structure made of stamped metal sheet, which is welded to the front of the base 200 through a continuous welding process. The baffle 202 and the front of the base 200 are flush. When the drawer 30 is closed in the box 20, the door 300 of the drawer 30 can abut against the baffle 202 without gaps, reducing radiation leakage.

[0060] Figure 7 A schematic diagram of the baffle frame structure is shown. (Combined with...) Figure 7 The baffle 202 has an assembly port 2021 that mates with the pick-up / placement port. The edge of the assembly port 2021 is provided with a folded edge 2022, which is connected to the base 200. The folded edge 2022 can be continuously welded to the pick-up / placement port. The folded edge 2022 can increase the connection area between the baffle 202 and the base 200, improve the reliability of the connection, and reduce radiation leakage.

[0061] Figure 8 It shows Figure 6 Another structural diagram from a different perspective, combined with Figure 8 The base 200 has a connecting hole 208, which is used to seal the connector of the antenna electrode 50. The connector can be a connecting bolt. Specifically, the base 200 has a connecting hole 208 at its bottom, and the connecting hole 208 and... Figure 3 The support columns 207 are set one-to-one, and the connection holes 208 penetrate the bottom of the base 200 and the corresponding support column 207. The connecting bolts can pass through the connection holes 208 from the outside to the inside and be locked with the nuts on the antenna plate 50, ensuring good electrical contact and sealing the connection holes 208 to prevent radiation leakage at the connection holes 208.

[0062] The side wall of the substrate 200 is provided with a feed inlet 209, which is used for the feed input connector 60 that is electrically connected to the antenna plate 50.

[0063] In related technologies, the antenna plate 50 located inside the substrate 200 needs to be connected to the power amplifier 40 on the outside of the substrate via a cable, and a feed port needs to be opened on the substrate; however, due to the large size of the feed port, radiation leakage is likely to occur, affecting the integrity of signal transmission and radiation suppression performance.

[0064] Based on the above-mentioned technical problems, this application provides a power input connector 60 for use in a radio frequency defrosting device 1. By connecting the antenna electrode 50 inside the substrate 200 through the power input connector 60, radiation leakage can be prevented to a certain extent, ensuring the integrity of signal transmission and radiation suppression performance.

[0065] Combination Figure 8 The side wall of the housing 20 is provided with a second recess 210, and the bottom of the second recess 210 is provided with a feed inlet 209. This arrangement allows the feed inlet 209 to be recessed into the side wall of the housing 20. When the power input connector 60 is assembled to the feed inlet 209, most of the power input connector 60 can be placed in the second recess 210, thus hiding the power input connector 60, reasonably setting the installation space, and improving the reliability of the assembly of the housing 20 and the support base 602.

[0066] Figure 9 A connection diagram of the power input connector 60 is shown. (Combined with...) Figure 8 as well as Figure 9 One end of the feed input connector 60 is connected to the antenna plate 50 inside the housing 20, and the other end of the feed input connector 60 is connected to the power amplifier 40 via a cable 70. The other end of the cable 70 is a standard N-type connector 80, which can be connected to the power amplifier 40. The cable 70 is a coaxial semi-rigid cable 70 or a high-performance shielded coaxial cable. The shielding effectiveness of the cable 70 is greater than 150dB, which can ensure ultra-low radiation leakage of the signal along the path.

[0067] Figure 10 It shows Figure 8 Side view diagram, Figure 11 It shows Figure 9 A schematic diagram of the AA cross section. Figure 12 for Figure 11 Enlarged diagram of point A, Figure 13 A schematic diagram of the power input connector 60 is shown. (Combined with...) Figure 12 as well as Figure 13The side wall of the housing 20 has a feed inlet 209, which can be located at the bottom of the base 200 and between two connection holes 208. The feed input connector 60 includes a feed pin 601, a support base 602, and a clamping member 603. The feed pin 601 passes through the feed inlet 209 and is used to connect to the antenna electrode 50. The clamping member 603 and the support base 602 are arranged opposite to each other. The support base 602 is connected to the feed pin 601 and is provided with a sealing protrusion 607. 03 is connected to the sealing protrusion 607 of the support base 602. The clamping member 603 and the support base 602 are arranged opposite to each other. When the feed pin 601 passes through the feed inlet 209, the feed pin 601 connects to the antenna plate 50 to realize the signal coupling between the antenna plate 50 and the feed input connector 60. At the same time, the support base 602 and the clamping member 603 are arranged opposite to each other on the side wall of the housing 20 to fix the feed input connector 60 to the side wall of the housing 20. The sealing protrusion 607 is adapted to pass through the feed inlet 209.

[0068] Combination Figure 12 as well as Figure 13 The clamping member 603 and the support base 602 are arranged opposite each other on the side wall of the housing 20. In one embodiment, the clamping member 603 is threadedly connected to the sealing protrusion 607. By rotating the clamping member 603, the clamping member 603 is screwed onto the sealing protrusion 607 towards the support base 602 until the clamping member 603 and the support base 602 are arranged opposite each other on the side wall of the housing 20, thus fixing the feed needle 601 to the feed inlet 209 of the housing 20. In addition, since the sealing protrusion 607 is adapted to pass through the feed inlet 209, the sealing protrusion 607 and the feed inlet 209 are in clearance fit to reduce radiation leakage. At the same time, since the dimensions of the support base 602 and the clamping member 603 are both larger than the feed inlet 209, the feed inlet 209 can be sealed, thereby preventing radiation leakage to a certain extent and ensuring the integrity of signal transmission and radiation suppression performance.

[0069] Combination Figure 12 as well as Figure 13 In one embodiment, the feed pin 601 has a rod-shaped structure. When the power input connector 60 is assembled into the feed inlet 209 of the housing 20, the support base 602 is located on the outside of the housing 20, and the clamping member 603 is located on the inside of the housing 20. In another embodiment, the power input connector 60 is assembled into the feed inlet 209 of the housing 20, the support base 602 is located on the inside of the housing 20, and the clamping member 603 is located on the outside of the housing 20.

[0070] In one embodiment, the power input connector 60 further includes a seal (not shown), which is sleeved on the feed pin 601 and disposed between the support 602 and the clamping member 603. When the power input connector is assembled into the feed inlet 209 of the housing 20, the seal is disposed between the support 602 and the housing 20 to further seal the feed inlet 209 and prevent radiation leakage. Specifically, the support 602 has a sealing groove on its side facing the clamping member 603, and the seal is embedded in the sealing groove. At least a portion of the seal protrudes from the sealing groove to abut against the side wall of the housing 20, ensuring the sealing performance of the seal for the feed inlet 209. In another embodiment, when the power input connector is assembled into the feed inlet 209 of the housing 20, a seal may also be disposed between the clamping member 603 and the housing 20 to further seal the feed inlet 209 and prevent radiation leakage. The arrangement of the seal on the clamping member 603 can be referenced from the arrangement of the seal on the support 602, and will not be described in detail here.

[0071] Combination Figure 12 as well as Figure 13 The feed input connector 60 also includes a connector 604, which connects to the feed pin 601. When the feed pin 601 passes through the antenna plate 50, the connector 604 abuts against the side of the antenna plate 50 facing away from the support base 602. That is, the connector 604 is located on the top of the antenna plate 50. Rotating the connector 604 causes it to rotate towards the antenna plate 50, thus abutting against it and connecting the antenna plate 50 and the feed pin 601. Furthermore, the support of the support column 207 at the bottom of the antenna plate 50 and the constraint of the connector 604 at the top of the antenna plate 50 ensure a stable connection between the antenna plate 50 and the feed pin 601.

[0072] Combination Figure 12 as well as Figure 13 A pad 605 is provided on the side of the connector 604 facing the support 602. The pad 605 is in planar contact with the antenna electrode 50, increasing the contact area and improving the firmness of the connector 604 in assembling the antenna electrode 50.

[0073] Combination Figure 12 as well as Figure 13A limiting member 606 is provided on the feed pin 601, and a clamping member 603 is disposed between the limiting member 606 and the support base 602. The limiting member 606 is located between the clamping member 603 and the connecting member 604. That is, along the axial direction of the feed pin 601, the support base 602, the clamping member 603, the limiting member 606, and the connecting member 604 are arranged sequentially. When the feed pin 601 passes through the antenna electrode 50, the limiting member 606 and the connecting member 604 abut against the two sides of the antenna electrode 50, respectively. That is, the antenna electrode 50 abuts against the top of the limiting member 606 and is located at the bottom of the connecting member 604. By screwing the connecting member 604 inward, the antenna electrode 50 and the feed pin 601 are fixedly connected, realizing the feeding of the antenna electrode 50, that is, the coupling of the radio frequency signal with the signal of the antenna electrode 50.

[0074] Combination Figure 12 as well as Figure 13 The tail of the feed needle 601 is the same size as the feed inlet 209. The head of the feed needle 601 is smaller than the tail. The limiting member 606 can be an annular protrusion fixedly connected to the head of the feed needle 601. The clamping member 603 and the connecting member 604 are both nut structures. The inner diameter of the clamping member 603 needs to be larger than the outer diameter of the limiting member 606 so that the clamping member 603 can be assembled from the head to the tail of the feed needle 601. In addition, the outer diameter of the limiting member 606 needs to be smaller than the size of the feed inlet 209 so that the connector 60 can be inserted into the housing 20 from the outside of the feed inlet 209.

[0075] During the process of assembling the feed input connector 60 to the feed inlet 209, first insert the feed pin 601 into the feed inlet 209, with the support base 602 abutting against the outer wall of the housing 20. Rotate the clamping part 603 to fix the feed input connector 60 onto the housing 20. Then place the antenna plate 50 onto the support column 207 and the limiting part 606 inside the housing 20. Next, assemble the connector 604 onto the head of the feed pin 601 and screw the connector 604 into the antenna plate 50 to connect the feed pin 601 to the antenna plate 50. The operation is simple, convenient and quick.

[0076] It should be noted that the gap of the feed needle 601 passes through the support base 602 and the sealing protrusion 607. The support base 602 and the sealing protrusion 607 have cavities inside. An insulating layer made of polytetrafluoroethylene or ceramic material is filled between the cavity and the feed needle 601. The feed needle 601 is connected to the wire in the cable 70.

[0077] The overall performance parameters of the feed input connector 60 of this application, which connects the antenna plate 50 and the power amplifier 40, are: impedance 50Ω, VSWR < 1.2, meeting the 300MHz frequency requirement.

[0078] Based on the same design concept, this application also provides an RF defrosting device 1, which includes the aforementioned RF defrosting chamber 20.

[0079] Based on the same design concept, this application also provides a refrigeration device, which includes the aforementioned radio frequency defrosting device 1. The refrigeration device can be a refrigerator, and the specific structure of the radio frequency defrosting device 1 can be referred to the relevant description above, which will not be repeated here.

[0080] In summary, the power input connector, radio frequency defrosting chamber, radio frequency defrosting device, and refrigeration equipment provided in this application can at least partially solve the risk of significant radiation leakage from the chamber, improve the chamber's radiation suppression capability, and have good practicality.

[0081] Unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
