[0030] Please refer to Figures 1 to 5 The present invention provides a heating element 100 for use in a microwave cooking device 200. The heating element 100 includes a mounting plate 12, a choke structure 14, and a heating tube 16. The choke structure 14 and the heating tube 16 are disposed on the mounting plate 12. The choke structure 14 has a receiving space 18, and the heating tube 16 is disposed in the receiving space 18. The choke structure 14 is configured to absorb microwaves radiated toward the receiving space 18.

[0031] In the aforementioned heating component 100, the heating tube 16 is disposed in the accommodating space 18 formed by the choke structure 14. The choke structure 14 can absorb microwaves radiated toward the accommodating space 18, thereby preventing the heating tube 16 from easily sparking, breaking down, burning, melting, or other phenomena caused by microwaves.

[0032] Specifically, the microwave cooking device 200 includes, but is not limited to, a microwave oven and a microwave-steam-grill combination appliance. The microwave cooking device 200 may include a microwave source 20, which includes, but is not limited to, a magnetron and an RF module. Figures 1 to 3 The microwave source 20 includes a magnetron, and the microwave cooking device 200 includes a waveguide 22 and a cavity 24. The waveguide 22 connects the cavity 24 and the magnetron. The magnetron is located on one side of the cavity 24, and the waveguide 22 can transmit the microwaves output from the magnetron to the cavity 24. Figure 2 In this design, the waveguide 22 can feed microwaves into the cavity 24 from the bottom. Optionally, a stirring antenna is provided at the bottom of the cavity 24, located at the microwave outlet of the waveguide 22, to stir the microwaves, enabling the microwaves to be transmitted to various locations within the cavity 24 and improving the uniformity of food cooking.

[0033] Optionally, in Figures 1 to 3 In this embodiment, the heating element 100 can serve as the top plate assembly of the cavity 24, and the mounting plate 12 serves as the top plate of the cavity 24. It is understood that the side plate where the microwave feed is located and the mounting plate 12 of the heating element 100 can be the same side plate or different side plates, and the present invention does not specifically limit this.

[0034] In related technologies, traditional microwave ovens are single-function microwave ovens. With the continuous improvement of user needs, combination microwave ovens with grilling or hot air functions have become the best-selling products on the market. However, when a heating element is added to a traditional microwave oven, an opening is reserved at the top of the cavity, and the heating element terminals must pass through the opening. In order to protect the heating element from impact, a metal heating element protective bracket also needs to be installed.

[0035] Because the protective frame is formed by welding several 304 stainless steel wires in parallel, and the gap between the long holes in the middle is large, 2.45GHz microwaves in microwave mode can penetrate the protective support of the heating tube, which can cause the wires of the heating tube to easily spark, break down, burn, melt, etc.

[0036] In this embodiment of the invention, the heating element 16 is disposed in the accommodating space 18 formed by the choke structure 14. The choke structure 14 can absorb microwaves radiated into the accommodating space 18, thereby preventing the heating element 16 from easily sparking, breaking down, burning, melting, or other phenomena caused by microwaves. In addition, the choke structure 14 can protect the heating element 16 disposed in the accommodating space 18 from impact, thereby eliminating the need for a metal protective frame, reducing costs, and allowing the heating assembly 100 to be installed as a whole, which is also easy to install onto the microwave cooking equipment 200, thereby fundamentally improving the reliability and lifespan of the microwave cooking equipment 200.

[0037] When the microwave cooking appliance 200 is operating in microwave mode, the microwave source 20 feeds microwaves into the cavity 24. The microwaves are transmitted to the choke structure 14, where they are absorbed by the oscillation circuit and converted into heat energy, thereby reducing the risk of arcing in the heating element 16. The choke structure 14 can be made of metal.

[0038] Heating element 16 includes, but is not limited to, graphene heating element 16. This invention does not specifically limit the number of heating elements 16. Figures 1 to 5 In this embodiment, there are two heating elements 16 and two choke structures 14. One choke structure 14 corresponds to one heating element 16. It is understood that in other embodiments, one choke structure 14 may correspond to two or more heating elements 16.

[0039] In some implementations, please refer to Figure 5 and Figure 6 The choke structure 14 includes two rows of choke teeth 26, which are arranged in opposite directions at intervals. The heating tube 16 is located in the accommodating space 18 formed by the two rows of choke teeth 26.

[0040] This makes it easy to install the heating element 16.

[0041] Specifically, in one embodiment, the heating element 16 can be installed on the mounting plate 12 first, and then two rows of choke teeth 26 can be installed on the mounting plate 12, so that the heating element 16 is located between the two rows of choke teeth 26. In another embodiment, one row of choke teeth 26 can be installed on the mounting plate 12 first, then the heating element 16 can be installed on the mounting plate 12, and finally the other row of choke teeth 26 can be installed on the heating element 16. In summary, when installing the heating element 16, there is more operating space for the heating element 16, which facilitates the installation of the heating element 16.

[0042] The connection methods between the choke tooth 26 and the mounting plate 12 include, but are not limited to, welding, snap-fit, bolts, etc., and the present invention does not specifically limit them. The connection methods between the heating element 16 and the mounting plate 12 include, but are not limited to, snap-fit, bolts, etc., and the present invention does not specifically limit them.

[0043] In some implementations, please refer to Figure 7 The choke tooth 26 includes a connecting portion 28, a first extension portion 30, and a second extension portion 32. The connecting portion 28 is connected to the mounting plate 12. The first extension portion 30 is connected to the end of the connecting portion 28 away from the heating tube 16. The second extension portion 32 is connected to the end of the first extension portion 30 away from the connecting portion 28 and extends toward another row of choke teeth 26. The first extension portion 30 is substantially perpendicular to the connecting portion 28, and the second extension portion 32 is substantially perpendicular to the first extension portion 30.

[0044] Thus, the accommodating space 18 can be formed through the structure of the aforementioned choke tooth 26.

[0045] Specifically, the connecting portion 28 can be fitted to the mounting plate 12. The first extension 30 extends away from the connecting portion 28 in a direction approximately perpendicular to it. The second extension 32 connects to the end of the first extension 30 away from the connecting portion 28 and extends towards the other row of choke teeth 26, thereby connecting the first extension 30 and the second extension 32 to form an L-shaped structure. The short side of the L-shaped structure faces the heating tube 16, placing the heating tube 16 in the middle position between the L-shaped structure formed by the two choke teeth 26. When microwaves enter the accommodating space 18 from the channel 33 between the ends of the two second extensions 32 of the two rows of choke teeth 26, they are absorbed by the oscillation circuit of the choke teeth 26 and converted into heat.

[0046] The term "approximately perpendicular" in this invention can mean that the included angle between the two is a right angle, or that the difference between the included angle and the right angle is within the expected range.

[0047] In some implementations, please refer to Figure 7 The sum of the lengths of the connecting part 28, the first extension part 30, and the second extension part 32 is equal to one-quarter of the microwave wavelength.

[0048] This can improve the microwave absorption effect.

[0049] Specifically, the length of the connecting part 28 is a1, the length of the first extension 30 is b1, and the length of the second extension 32 is c1, where a1 + b1 + c1 = λ / 4, and λ is the microwave wavelength. In one example, the microwave operating frequency f of the microwave cooking device 200 is 2.45 GHz. According to c = λ × f, then a1 + b1 + c1 = c / f × 1 / 4 ≈ 31 mm, where c is the speed of light. The choke tooth 26, satisfying a1 + b1 + c1 = λ / 4, can improve the microwave absorption effect and play a role in microwave shielding.

[0050] In some implementations, please refer to Figure 5 and Figure 8 The choke tooth 26 includes a third extension 34, which is connected to the end of the second extension 32 away from the first extension 30 and extends toward the connecting portion 28. The third extension 34 is substantially perpendicular to the second extension 32.

[0051] Thus, the accommodating space 18 can be formed through the structure of the aforementioned choke tooth 26.

[0052] Specifically, the connecting portion 28 can be attached to the mounting plate 12. The first extension 30 extends away from the connecting portion 28 in a direction approximately perpendicular to it. The second extension 32 connects to the end of the first extension 30 away from the connecting portion 28 and extends towards the other row of choke teeth 26, thereby connecting the first extension 30 and the second extension 32 to form an L-shaped structure with the short side of the L-shaped structure facing the heating tube 16. The third extension 34 connects to the end of the second extension 32 away from the first extension 30 and extends towards the connecting portion 28, so that the heating tube 16 is located in the middle position between the L-shaped structure formed by the two choke teeth 26, and the third extension 34 is closer to the heating tube 16. When microwaves enter the accommodating space 18 from the channel between the ends of the two second extensions 32 of the two rows of choke teeth 26, they are absorbed by the oscillation circuit of the choke teeth 26 and converted into heat.

[0053] In some implementations, please refer to Figure 8 The sum of the lengths of the connecting part 28, the first extension part 30, the second extension part 32 and the third extension part 34 is equal to one-quarter of the microwave wavelength.

[0054] This can improve the microwave absorption effect.

[0055] Specifically, the length of the connecting part 28 is a2, the length of the first extension 30 is b2, the length of the second extension 32 is c2, and the length of the third extension 34 is e, where a2 + b2 + c2 + e = λ / 4, and λ is the microwave wavelength. In one example, the microwave operating frequency f of the microwave cooking device 200 is 2.45 GHz. According to c = λ × f, then a2 + b2 + c2 + e = c / f × 1 / 4 ≈ 31 mm, where c is the speed of light. The choke tooth 26, satisfying a2 + b2 + c2 + e = λ / 4, can improve the microwave absorption effect and play a role in microwave shielding.

[0056] In some implementations, please refer to Figure 4 and Figure 6 The mounting plate 12 is provided with a receiving groove 36, and the heating tube 16 includes a tube body 38. The choke structure 14 and the tube body 38 are located in the receiving groove 36.

[0057] This protects the choke structure 14 and the heating element 16 from damage due to impact.

[0058] Specifically, the tube body 38 can be the heating component of the heating element 16, and the tube body 38 may be provided with tubing. The tube body 38 and the choke structure 14 are disposed in the receiving groove 36, which can protect the tube body 38 and the choke structure 14 from damage caused by impact due to the choke structure 14 and the tube body 38 protruding from the surface of the mounting plate 12, thereby improving the service life of the choke structure 14 and the heating element 16.

[0059] Alternatively, the mounting plate 12 can be formed by pressing to create the receiving groove 36, thereby improving the manufacturing efficiency of the mounting plate 12.

[0060] In some implementations, please refer to Figure 4 and Figure 6 The heating element 16 includes a first connector 40 and a second connector 42. The first connector 40 and the second connector 42 are respectively connected to both ends of the tube body 38. The first connector 40 passes through the first side wall 44 of the receiving groove 36, and the second connector 42 passes through the second side wall 46 of the receiving groove 36 opposite to the first side wall 44.

[0061] Therefore, it is convenient to connect an external power source to the heating element 16.

[0062] Specifically, the tube body 38 is disposed in the receiving groove 36, which can protect the tube body 38. The first connector 40 passes through the first side wall 44, and the second connector 42 passes through the second side wall 46, so that an external power source can be connected to the first connector 40 and the second connector 42 extending out of the receiving groove 36 to supply power to the tube body 38, causing the tube body 38 to heat up.

[0063] In some implementations, please refer to Figure 6 The length of the choke structure 14 is not less than the length of the tube body 38.

[0064] Therefore, the tube body 38 can be located entirely within the accommodating space 18.

[0065] Specifically, the length of the choke structure 14 is L1, and the length of the tube body 38 is L2, where L1 ≥ L2. This effectively prevents microwave energy from entering the interior of the heating tube 16, thereby reducing arcing of the heating tube 16 wires and reducing microwave leakage at the terminals of the heating tube 16.

[0066] In one implementation, L1 = L2, and in another implementation, L1 > L2.

[0067] Please combine Figures 1 to 3 The microwave cooking device 200 provided in the embodiments of the present invention includes the heating element 100 of any of the above embodiments.

[0068] Specifically, the microwave cooking device 200 includes, but is not limited to, a microwave oven and a microwave-steam-grill combination appliance. The microwave cooking device 200 may include a microwave source 20, which includes, but is not limited to, a magnetron and an RF module. Figure 2 The microwave source 20 includes a magnetron, and the microwave cooking device 200 includes a waveguide 22 and a cavity 24. The waveguide 22 connects the cavity 24 and the magnetron. The magnetron is located on one side of the cavity 24, and the waveguide 22 can transmit the microwaves output from the magnetron to the cavity 24. Figure 2In this design, the waveguide 22 can feed microwaves into the cavity 24 from the bottom. Optionally, a stirring antenna is provided at the bottom of the cavity 24, located at the microwave outlet of the waveguide 22, to stir the microwaves, enabling the microwaves to be transmitted to various locations within the cavity 24 and improving the uniformity of food cooking.

[0069] In some implementations, please refer to Figures 1 to 3 The microwave cooking device 200 includes a cavity 24, and the mounting plate 12 is the top plate of the cavity 24.

[0070] Thus, the microwave cooking appliance 200 can form a top-heated cavity 24 structure.

[0071] Specifically, the heating element 100 can constitute the top plate assembly of the cavity 24. In one embodiment, the cavity 24 includes a U-shaped plate 48, a bottom plate 50, and a top plate, with the mounting plate 12 serving as the top plate of the cavity 24. The upper and lower sides of the U-shaped plate 48 are open sides, and the top plate and bottom plate 50 are respectively connected to the upper and lower sides of the U-shaped plate 48. Microwaves can be fed into the cavity 24 from the bottom plate 50, and the heating tube 16 on the top plate can generate heat, thereby forming a vertical heating field for the food and improving the uniformity of food heating.

[0072] Alternatively, the U-shaped plate 48 can be connected to the bottom plate 50 and the top plate by welding.

[0073] In summary, the heating element 16 assembly in the microwave cooking device 200 of the present invention has a simple structure and high reliability. By adding a choke structure 14 to the mounting plate 12, the heating element 16 can be effectively prevented from being broken down by arcing, and the actual test results are very good.

[0074] Specifically, since the heating element 16 is entirely placed inside the cavity 24, its metal heating wire will sense microwaves, and microwaves will leak to the outside at its terminals. In principle, the microwave cooking device 200 of the present invention shields microwaves, preventing microwave energy from entering the interior of the heating element 16, thereby reducing arcing of the heating element 16 wire and reducing microwave leakage at the terminals.

[0075] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of the invention.
