[0034] In related technologies, a microwave oven is a modern cooking appliance that uses microwaves to heat food. A microwave oven consists of a power supply, a magnetron, a control circuit, and a cooking cavity. The power supply provides high voltage to the magnetron, which, under the excitation of the power supply, continuously generates microwaves. The magnetron is connected to a stirring antenna via a waveguide to transmit the microwaves to the stirring antenna. The stirring antenna then emits the microwaves to various parts of the cooking cavity during its rotation, heating the food inside. However, this type of microwave oven, where microwaves are generated by a magnetron, may experience uneven heating, resulting in burnt or uncooked portions.

[0035] Radio frequency (RF) heating technology can be used to improve and solve the problem of uneven heating in microwave ovens. An RF heating system includes a DC power supply, signal board, microwave source, RF cables, and antenna. Currently, there are two main connection methods for RF heating systems. One method involves connecting the microwave transmitter to a waveguide, fixing the RF antenna to the waveguide, and then feeding the microwaves into the cooking cavity through the waveguide and RF antenna. The other method involves fixing the antenna to the cavity, directly feeding the microwaves into the cavity.

[0036] However, existing waveguide-fed antenna assemblies are relatively large, and the waveguide is usually mounted on the cavity by connecting the flange on the waveguide with screws. However, this method is very complicated and cumbersome, which is not conducive to mass production.

[0037] Meanwhile, the installation scheme of directly connecting the microwave source to the waveguide makes the assembly more complicated and imposes more structural restrictions. Both the microwave source and the waveguide occupy a lot of space, which will affect the installation of other components.

[0038] Please refer to Figures 1 and 2. An antenna bracket 10 according to an embodiment of this application is used for a microwave cooking device 100.

[0039] The antenna bracket 10 includes a base 12 and a fastener 14. The base 12 is used to mount the antenna and is fixed to the cavity 20 of the microwave cooking appliance 100 by the fastener 14.

[0040] The antenna bracket 10 and fastener 14 fix the base 12 to the cavity 20 of the microwave cooking equipment 100. The assembly process is simple, with few steps, and is easy to manufacture.

[0041] Specifically, microwave cooking equipment 100 includes, but is not limited to, microwave ovens, ovens with microwave functions, steam ovens, and integrated cooking equipment.

[0042] In other embodiments, the antenna bracket 10 provided in this application can also be used in microwave drying equipment, microwave sterilization equipment, etc.

[0043] Antenna bracket 10 is used in microwave cooking appliance 100. Microwave cooking appliance 100 has a cavity 20 for placing the object to be processed. Antenna bracket 10 is mounted on the wall of cavity 20 and is used to fix the antenna to cavity 20, while also electrically connecting the antenna to a microwave transmitting device. This allows microwaves generated by the microwave transmitting device to be fed into the cavity 20 through the antenna.

[0044] The antenna bracket 10 is fixed to the wall of the cavity 20 by fasteners 14. During installation, simply place the antenna bracket 10 in the corresponding installation position on the cavity 20 and then fix it with the fasteners 14 to complete the installation. This makes the assembly of the antenna bracket 10 on the microwave cooking equipment 100 simple and convenient, which is beneficial to production and processing.

[0045] Referring to Figure 2, in some embodiments, the base 12 includes a mounting base 16 and a connecting portion 18 connected to each other. The connecting portion 18 is configured to pass through the mounting hole 22 of the cavity 20 to extend into the cavity 20. The portion of the connecting portion 18 located inside the cavity 20 is connected to the fastener 14 to fix the antenna bracket 10. The mounting base 16 is configured to be located outside the cavity 20 and connected to the transmission cable 28 of the microwave transmitting device.

[0046] Thus, by passing through the mounting hole 22 of the cavity 20 and being fixedly connected to the fastener 14 via the connecting part 18 of the base 12, the base 12 can be firmly fixed to the cavity 20.

[0047] Specifically, the base 12 includes a mounting base 16 and a connecting part 18 connected to each other. The mounting base 16 is used to connect to the transmission cable 28 of the microwave transmitting device. The connecting part 18 passes through the mounting hole 22 of the cavity 20 and extends into the cavity 20. The fastener 14 is connected to the part of the connecting part 18 located inside the cavity 20. Thus, the mounting base 16 and the fastener 14 are located on both sides of the inner wall of the cavity 20 of the microwave cooking equipment 100. When the fastener 14 is connected to the connecting part 18, the fastener 14 and the mounting base 16 can clamp the wall of the cavity 20 to fix the base 12.

[0048] Please refer to Figure 4. In some embodiments, the base 12 further includes a mounting part 24, which is fixedly connected to the connecting part 18. The mounting part 24 is used to mount the antenna. The mounting base 16 is provided with an interface 26, and the transmission cable 28 extends into the interface 26 and is electrically connected to the mounting part 24.

[0049] In this way, the electrical connection between the antenna and the microwave transmitting device can be achieved through the antenna bracket 10.

[0050] Specifically, the base 12 includes a mounting base 16, a connecting part 18, and a mounting part 24 connected in sequence. The mounting base 16 has a stainless steel outer shell and a conductive inner core, with an air layer between the stainless steel outer shell and the conductive inner core.

[0051] The stainless steel casing has excellent corrosion resistance, resisting most chemicals and environmental factors, thus extending the service life of the antenna bracket 10. Furthermore, the stainless steel casing is highly durable and not easily damaged by environmental factors, reducing the frequency of maintenance and replacement.

[0052] An air layer, filling the antenna bracket 10, serves as one of the media for antenna radiation. The air layer helps improve the antenna's radiation characteristics and impedance matching performance. Simultaneously, the air layer significantly reduces the overall weight, facilitating the installation and transportation of the antenna bracket 10.

[0053] The conductive core is a key part of the antenna's operation, responsible for transmitting current to the antenna radiator. Good conductivity can reduce current loss during transmission and improve the antenna's radiation efficiency.

[0054] The connecting part 18 and the mounting part 24 are made of conductive material and are connected to the conductive inner core of the mounting base 16. The transmission cable 28 extends into the interface 26 and is electrically connected to the conductive inner core of the mounting base 16. The mounting part 24 is electrically connected to the antenna, thus realizing the electrical connection between the antenna and the microwave transmitting device.

[0055] Please refer to Figure 1. In some embodiments, the transmission cable 28 is fixedly connected to the interface 26.

[0056] In this way, the installation steps can be reduced when installing the antenna bracket 10, making the assembly process simpler.

[0057] Specifically, the transmission cable 28 is fixedly connected to the interface 26, so when the antenna bracket 10 is installed into the cavity 20 of the microwave cooking appliance 100, there is no need to connect the transmission cable 28 and the base 12 separately. Furthermore, since no additional connecting device is needed between the transmission cable 28 and the interface 26, the height of the base 12 can be reduced.

[0058] In one example, the transmission cable 28 is fixedly connected to the interface 26, and the height of the mounting base 16 is 10mm. In a plug-in connection where the transmission cable 28 and interface 26 are connected, the height of the mounting base 16 is 20-30mm. Thus, by fixing the transmission cable 28 to the interface 26, the size of the base 12 can be significantly reduced, saving space for the arrangement of other components in the microwave cooking appliance 100. It also facilitates the miniaturization of the microwave cooking appliance 100.

[0059] In one embodiment, the transmission cable 28 extends into the interface 26, and the transmission cable 28 and the conductive inner core of the mounting base 16 are fixed together by soldering. The soldering connection process is simple, has little impact or damage on the workpiece, and can form a stable and reliable solder joint with good strength and sealing, thereby resulting in a high connection strength and reliable connection between the transmission cable 28 and the conductive inner core.

[0060] Alternatively, the transmission cable 28 and the conductive inner core can also be connected by twisted wire connection, laser welding, conductive adhesive connection, or other methods.

[0061] In other ways, the transmission cable 28 and the conductive inner core can also be connected in a pluggable manner. For example, the transmission cable 28 and the conductive inner core can be connected by a plug. One end of the transmission cable 28 is provided with a plug, and the mounting base 16 is provided with a socket. When installing, the plug is inserted into the socket to realize the electrical connection between the transmission cable 28 and the conductive inner core.

[0062] Please refer to Figures 3 and 4. In some embodiments, the peripheral surface of the connecting part 18 is provided with external threads, the fastener 14 includes a nut, and the connecting part 18 passes through the mounting hole 22 and is fixedly connected to the nut to fix the base 12 to the cavity 20 of the microwave cooking device 100.

[0063] This makes the connection between the base 12 and the fastener 14 more convenient and reliable, and facilitates processing and assembly.

[0064] Specifically, when the base 12 is installed onto the cavity 20, the cavity 20 has a mounting hole 22. The mounting part 24 and the connecting part 18 of the base 12 are inserted into the mounting hole 22 from top to bottom. The fastener 14 is fitted onto the connecting part 18 from bottom to top and tightened, so that the wall of the cavity 20 is clamped between the fastener 14 and the mounting base 16, thereby completing the fixation of the base 12.

[0065] The threaded connection simplifies the workpiece processing, makes the connection convenient and reliable, and is conducive to mass production and improves assembly efficiency.

[0066] Please refer to Figures 1 and 2. In some embodiments, the bottom surface of the mounting base 16 is provided with a fixing part 30, which abuts against the outer wall surface of the cavity 20 when the base 12 is installed into the cavity 20.

[0067] Thus, when the base 12 is installed into the cavity 20, fixing the wall of the cavity 20 between the fixing part 30 and the fastener 14 can securely fix the antenna bracket 10 onto the cavity 20.

[0068] Specifically, the bottom surface of the mounting base 16 is provided with a fixing part 30, which abuts against the outer wall surface of the cavity 20. Thus, when the base 12 is installed into the cavity 20, the fixing part 30 and the fastener 14 clamp the wall surface of the cavity 20 between them, facilitating the stable and reliable installation of the mounting base 16. Simultaneously, the fixing part 30 limits the length of the connecting part 18 extending into the mounting hole 22. When installing the base 12, the mounting part 24 and the connecting part 18 are inserted into the mounting hole 22 sequentially from top to bottom until the fixing part 30 abuts against the outer wall surface of the cavity 20, indicating that the installation is in place. No additional positioning is required, simplifying the assembly process.

[0069] In other embodiments, the fixing part 30 is disposed above the connecting part 18. When installing the base 12, the base 12 is placed inside the cavity 20, and the mounting base 16 extends from bottom to top through the mounting hole 22 until the upper surface of the fixing part 30 abuts against the inner wall of the cavity 20. Then, the fastener 14 is used to fix it to the connecting part 18, completing the assembly of the base 12. In this way, the assembly of the base 12 can be completed inside the cavity 20, eliminating the need for installation from both the outside and inside of the cavity 20, thus simplifying the assembly process.

[0070] In one embodiment, as shown in FIG1, the fixing part 30 includes a flange. The flange is disposed on the bottom surface of the mounting base 16, which can increase the contact area between the mounting base 16 and the outer wall surface of the cavity 20 when the mounting base 16 is fixed with the fastener 14, thereby ensuring the stability of the mounting base 16.

[0071] Referring to Figure 4, in some embodiments, the antenna bracket 10 includes a sealing ring 32 disposed between the fixing part 30 and the fastener 14.

[0072] This prevents water or air leakage from cavity 20.

[0073] Specifically, the cavity 20 has mounting holes 22, allowing the base 12 to be fixed to the cavity 20 by fasteners 14. The cavity 20 of the microwave cooking device 100 can form a cooking cavity, and an antenna connected to a microwave transmitting device feeds microwaves into the cooking cavity, thereby heating the food inside the cooking cavity.

[0074] The sealing ring 32 is disposed between the fixing part 30 and the fastener 14. When the base 12 is installed in the cavity 20, the sealing ring 32 can be installed on the inner side wall of the cavity 20, or the sealing ring 32 can be installed on the outer side wall of the cavity 20. That is, the sealing ring 32 can be located between the fixing part 30 and the wall of the cavity 20, or the sealing ring 32 can be located between the wall of the cavity 20 and the fastener 14.

[0075] The sealing ring 32 used in the microwave cooking equipment 100 includes materials such as high-temperature resistant, aging-resistant, and corrosion-resistant rubber and silicone rubber. The silicone rubber sealing ring 32 has the characteristics of high temperature resistance, aging resistance, corrosion resistance, softness and pressure resistance, which can effectively prevent water or air leakage in the cavity 20 and adapt to the high-temperature environment inside the cooking cavity.

[0076] In some embodiments, the antenna support 10 includes a copper mesh disposed between the fixing part 30 and the fastener 14.

[0077] This prevents microwave leakage.

[0078] Specifically, microwaves penetrate some materials when propagating in space, but are also absorbed or reflected by others. Copper mesh, as a metal grid, has dense metal lines that can form a reflective surface for electromagnetic waves, thus blocking microwave penetration to some extent.

[0079] When installing the antenna bracket 10, mounting holes 22 need to be made in the cavity 20. To prevent microwave leakage, a copper mesh is placed between the fixing part 30 and the fastener 14. When the base 12 is installed in the cavity 20, the copper mesh can be installed on the inner wall of the cavity 20, or the copper mesh can be installed on the outer wall of the cavity 20. That is, the copper mesh can be located between the fixing part 30 and the wall of the cavity 20, or the copper mesh can be located between the wall of the cavity 20 and the fastener 14.

[0080] In summary, the antenna structure includes a base 12 and a fastener 14. A mounting hole 22 is provided in the cavity 20 of the microwave device. The connecting portion 18 of the base 12 passes through the cavity 20 and connects with the fastener 14, thus fixing the base 12. Simultaneously, a sealing ring 32 and a copper ring can be provided between the fastener 14 and the inner wall of the cavity 20, and between the fixing portion 30 of the base 12 and the outer wall of the cavity 20, to prevent water mist and gas leakage that may occur inside the cavity 20, and to prevent microwave leakage.

[0081] With the aforementioned structure and connection method of the antenna bracket 10, since the transmission cable 28 and the antenna base 12 are fixedly connected, the connectors used for electrical connection between the cable and the base 12 can be saved, thus reducing the cost of the antenna bracket 10. Furthermore, because the transmission cable 28 and the antenna base 12 are fixedly connected, the height of the portion of the base 12 outside the cavity 20 can be significantly reduced, resulting in a smaller size and making the layout of various components on the microwave cooking appliance 100 more convenient. In addition, the antenna is easy to install in the cavity 20 of the microwave cooking appliance 100, while also preventing water leakage, air leakage, and microwave leakage.

[0082] A microwave cooking device 100 according to an embodiment of this application includes a cavity 20, a microwave transmitting device, and an antenna assembly. The antenna assembly includes an antenna and an antenna bracket 10 according to any of the above embodiments. The antenna is mounted on the antenna bracket 10, and the antenna bracket 10 is mounted on the cavity 20. The antenna bracket 10 connects the transmission cable 28 of the microwave transmitting device to the antenna so that the microwave transmitting device transmits microwaves to the antenna.

[0083] The microwave cooking device 100 described above uses fasteners 14 to fix the base 12 to the cavity 20 of the microwave cooking device 100. The assembly process is simple, with few steps, and is easy to manufacture.

[0084] Specifically, the microwave cooking appliance 100 has a cooking cavity in its cavity 20. A microwave transmitting device and an antenna assembly are disposed outside the cavity 20. The microwave transmitting device is connected to the antenna assembly via a transmission cable 28. The microwave transmitting device generates microwaves and transmits them to the antenna, which feeds the microwaves into the cavity 20 to generate a uniform microwave field inside the cavity 20, thereby enabling the food inside the cavity 20 to be heated using microwaves.

[0085] In some embodiments, the cavity 20 has a mounting hole 22, and the base 12 includes a connecting part 18, which passes through the mounting hole 22 and is fixedly connected to the fastener 14 so that the base 12 is fixed on the cavity 20 of the microwave cooking device 100.

[0086] In this way, the base 12 can be fixed by clamping the wall of the cavity 20 with the fastener 14 and the mounting base 16.

[0087] Specifically, the connecting part 18 passes through the mounting hole 22 of the cavity 20 and extends into the cavity 20. The fastener 14 is connected to the part of the connecting part 18 located inside the cavity 20. The mounting base 16 and the fastener 14 are located on both sides of the inner wall of the cavity 20 of the microwave cooking equipment 100. When the fastener 14 is connected to the connecting part 18, the fastener 14 and the mounting base 16 can clamp the wall of the cavity 20 to fix the base 12.
