Description

Technical Field

[0001] This application relates to the field of microwave device technology, and more particularly to a cooking component and a microwave oven. Background Technology

[0002] Microwave ovens use microwaves to heat food inside. In related technologies, microwave ovens use a stirring device to change the direction of microwave emission, thereby improving the uniformity of microwave distribution within the oven. However, this type of microwave oven still has a large microwave distribution blind zone inside, resulting in poor heating uniformity. Furthermore, the stirring device has a relatively complex structure, occupies a large space in the microwave oven, and leads to a relatively low volumetric efficiency. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide a cooking component and a microwave oven that are conducive to improving the heating uniformity of the microwave oven, and at the same time, also conducive to improving the volume ratio of the microwave oven.

[0004] To solve the above problems, the technical solution of this application embodiment is implemented as follows:

[0005] This application provides a cooking component for use in a microwave oven, the cooking component comprising:

[0006] The enclosure is formed by surrounding a cavity. Multiple microwave induction areas are provided on the cavity wall. Each microwave induction area includes a microwave feed port that penetrates the cavity wall. Each microwave induction area is located on a different side of the cavity.

[0007] The number of waveguides corresponds one-to-one with the number of microwave induction areas. Each waveguide is disposed on the outside of the housing and forms a microwave channel with the outer wall of the housing. Each microwave channel is connected to one microwave induction area.

[0008] A magnetron is used to generate microwaves. The number of magnetrons corresponds one-to-one with the number of waveguides. Each magnetron is disposed on a waveguide, and the microwaves generated by each magnetron can enter the microwave channel corresponding to that magnetron.

[0009] In some embodiments, the plurality of microwave induction regions include a first microwave induction region and a second microwave induction region, wherein the perpendicular line from the side containing the first microwave induction region intersects the perpendicular line from the side containing the second microwave induction region.

[0010] In some embodiments, the housing includes a top plate and a bottom plate spaced apart along the height direction of the cooking assembly, and the plates on the other sides of the housing besides the top plate and the bottom plate are side plates;

[0011] The microwave feed port of the first microwave induction area is a first microwave feed port, which is located on the side plate. The microwave feed port of the second microwave induction area is a second microwave feed port, which is located on the top plate or the bottom plate.

[0012] In some embodiments, the number of the first microwave feed ports is not less than one; and / or, the number of the second microwave feed ports is not less than four.

[0013] In some embodiments, the magnetron corresponding to the first microwave inlet region is a first magnetron, which includes a first antenna cap. In the height direction of the cooking assembly, the distance between the center of the first antenna cap and the center of the first microwave feed port ranges from 60 mm to 80 mm.

[0014] In some embodiments, the first microwave feed port is circular in shape, and the diameter of the first microwave feed port is smaller than the width of the side plate, wherein the width of the side plate is the dimension of the side plate in the direction perpendicular to the height of the cooking assembly; and / or,

[0015] The second microwave feed port is circular in shape, and the diameter of the second microwave feed port is smaller than the width of the top plate or the bottom plate.

[0016] In some embodiments, the first microwave feed port is formed by multiple sides;

[0017] The longest side of the first microwave feed port has an extension length less than the width of the side plate and greater than or equal to 40 mm, wherein the width of the side plate is the dimension of the side plate in the direction perpendicular to the height of the cooking assembly; and / or, the shortest side of the first microwave feed port has an extension length greater than or equal to 10 mm.

[0018] In some embodiments, the second microwave feed port is formed by multiple sides;

[0019] The longest side of the second microwave feed port has an extension length less than the width of the top plate or the bottom plate, and is greater than or equal to 40 mm; and / or, the shortest side of the second microwave feed port has an extension length greater than or equal to 10 mm.

[0020] In some embodiments, there are multiple second microwave feed ports, and at least two of the second microwave feed ports have different diameters or the dimensions of their longest sides.

[0021] In some embodiments, the diameter or the length of the longest side of any two second microwave feed ports is different.

[0022] In some embodiments, the waveguide corresponding to the second microwave induction region is a second waveguide, and the magnetron corresponding to the second microwave induction region is a second magnetron. The second waveguide includes a first sub-segment and a second sub-segment arranged along the height direction of the cooking component. The first sub-segment is connected to the second microwave induction region through the second sub-segment. The second magnetron is disposed in the first sub-segment, and the diameter of the second sub-segment is larger than the diameter of the second sub-segment.

[0023] In some embodiments, the first sub-segment is located on the side of the second sub-segment opposite to the housing.

[0024] This application also provides a microwave oven, which includes the cooking components described in any of the above embodiments.

[0025] The cooking component of this application embodiment, when applied to a microwave oven, allows microwaves to be fed in from at least both sides of the cooking cavity. These microwaves work synergistically to cover at least partially the areas that the other cannot reach, thus increasing the microwave coverage area within the cooking cavity and improving heating uniformity. Simultaneously, the microwave oven can improve heating uniformity without requiring a stirring device. Therefore, without changing the overall size of the microwave oven, it is advantageous to increase the volume of the cooking cavity, i.e., to improve the microwave oven's volumetric efficiency. Furthermore, by coordinating the power and frequency of each magnetron, uniform heating of the food on different sides can be achieved, and changing the power and frequency of the first and second magnetrons is relatively simple and easy to implement.

[0042] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] This application provides a microwave oven, which includes the cooking components of any embodiment of this application.

[0044] This application does not limit the specific type of microwave oven. For example, it can be a flatbed microwave oven, a turntable microwave oven, or a built-in microwave oven, etc.

[0045] It should be noted that the microwave oven, after adopting the cooking component of any embodiment of this application, has all the advantages of the cooking component of the corresponding embodiment, and the specific advantages will be described in detail in the following embodiments.

[0046] The cooking component can be understood as the main part of a microwave oven. Specifically, the cooking component has a cooking cavity where food is heated.

[0047] Figure 1 An exploded view of a portion of the structure of a cooking component 100' in the related art is shown. Please refer to... Figure 1The cooking component 100' in the related technology includes a housing 10', a waveguide 20', a magnetron 30', and a stirring device 70'. The stirring device 70' includes a motor 73', a motor bracket 72', and a stirring antenna 71'. A microwave channel is defined between the waveguide 20' and the housing 10'. Microwaves emitted by the magnetron 30' are fed into the cooking cavity from the bottom of the housing 10' through the microwave channel. The stirring antenna 71' is provided with a microwave feed port. The motor 73' drives the stirring antenna 71' to rotate to change the position of the microwave feed port, thereby changing the direction of the microwaves fed into the cooking cavity through the microwave feed port. This allows the microwaves to reach more areas within the cooking cavity, improving the uniformity of heating within the cooking cavity. However, with this type of microwave oven, there are often blind spots in the microwave coverage at the four corners of the bottom of the oven body 10'. That is, there are still large microwave distribution blind spots in the cooking cavity, resulting in poor heating uniformity. In addition, the motor and stirring antenna need to move continuously, which requires sufficient space for movement, thus occupying a large space in the microwave oven and making the volume ratio of the microwave oven relatively low.

[0048] In view of this, please refer to Figures 2 to 8 This application provides a cooking component 100, which includes a housing 10, a waveguide 20, and a magnetron 30.

[0049] The enclosure 10 forms a cavity 10a. Multiple microwave induction zones are provided on the cavity wall of the cavity 10a, and each microwave induction zone includes a microwave feed port 10b. It can be understood that a microwave induction zone is the collection of all microwave feed ports 10b on one side of the cavity wall of the cavity 10a. That is, all microwave feed ports 10b on the same side of the cavity 10a are collectively referred to as a microwave induction zone.

[0050] Each microwave guiding region is located on a different side of the cavity 10a. For example, the cavity 10a has a cuboid structure, in which case the cavity 10a has six sides, wherein microwave guiding regions are provided on at least two sidewalls. Here, the specific location of these two sides on the cavity 10a is not limited. For example, they could be opposite sides of the cavity 10a, or adjacent sides of the cavity 10a.

[0051] The microwave feed port 10b penetrates the cavity wall of the cavity 10a. In this way, microwaves from outside the housing 10 can enter the cavity 10a through the microwave feed port 10b.

[0052] The number of waveguides 20 corresponds one-to-one with the number of microwave introduction areas. Each waveguide 20 is located on the outside of the housing 10 and forms a microwave channel with the outer wall of the housing 10. Each microwave channel connects to a microwave introduction area. Here, each microwave channel is located outside the housing 10.

[0053] For example, please refer to Figure 2 and Figure 3There are two microwave induction zones, one of which is the first microwave induction zone and the other is the second microwave induction zone. There are also two waveguides 20, one of which is the first waveguide 80 corresponding to the first microwave induction zone and the other of which is the second waveguide 60 corresponding to the second microwave induction zone. The microwave channel formed between the first waveguide 80 and the outer wall of the housing 10 is the first microwave channel, and the microwave channel formed between the second waveguide 60 and the outer wall of the housing 10 is the second microwave channel. The first microwave channel is connected to the first microwave induction zone, and the second microwave channel is connected to the second microwave induction zone.

[0054] Microwaves from the first microwave channel are fed into the cavity 10a via the first microwave induction region, and microwaves from the second microwave channel are fed into the cavity 10a via the second microwave induction region. Since the first and second microwave induction regions are located on different sides of the cavity 10a, microwaves can be introduced from both sides of the cavity 10a. The microwaves introduced from at least both sides of the cavity 10a work synergistically to cover at least a portion of the areas that the other cannot reach. This improves the microwave coverage area inside the cavity 10a, thereby enhancing the uniformity of heating.

[0055] Meanwhile, by introducing microwaves from at least both sides of the cavity 10a, the uniformity of heating in the microwave oven can be improved. Therefore, the microwave oven does not need to be equipped with a stirring device. Thus, without changing the overall size of the microwave oven, it is beneficial to increase the volume of the cooking cavity, that is, to improve the volumetric efficiency of the microwave oven. Furthermore, since motors have certain reliability issues, eliminating the motor in the microwave oven eliminates the failure rate caused by motor malfunctions, thereby improving the reliability of the microwave oven.

[0056] The magnetron 30 is used to generate microwaves. The number of magnetrons 30 corresponds one-to-one with the number of waveguides 20. Each magnetron 30 is disposed on a waveguide 20, and the microwaves generated by each magnetron 30 can enter the microwave channel corresponding to that magnetron 30.

[0057] For example, please refer to Figure 2 and Figure 3 There are also two magnetrons 30, including a first magnetron 40 and a second magnetron 50. The microwaves generated by the first magnetron 40 enter the first microwave channel, and the microwaves generated by the second magnetron 50 enter the second microwave channel.

[0058] It is understandable that the microwaves entering the cavity 10a can be considered as a whole, with the microwaves fed into the cavity 10a from the first microwave inlet area and the microwaves fed into the cavity 10a from the second microwave inlet area each accounting for a portion of this whole. By coordinating the power and frequency of the first magnetron 40 and the second magnetron 50, the proportions of the two can be changed, thereby achieving uniform heating of the food on different sides. Changing the power and frequency of the first magnetron 40 and the second magnetron 50 is relatively simple and easy to implement.

[0059] In some embodiments, the cooking assembly 100 may further include an inner partition disposed within the cavity 10a and covering each microwave inlet area. Thus, the side of the inner partition facing away from the microwave inlet area and the cavity wall of the cavity 10a define a cooking cavity. That is, a portion of the space in the cavity 10a is used to form the cooking cavity, which is separated from the microwave feed port 10b by the inner partition. Food residues and broth generated during heating within the cooking cavity are blocked by the inner partition, preventing them from entering the microwave channel through the microwave feed port 10b. It is understood that food residues and broth within the cooking cavity are easier to clean, which is beneficial to user health; furthermore, it prevents fire hazards caused by prolonged heating of uncleaned food residues. It should be noted that the specific type of the inner partition is not limited; for example, it can be a glass plate, mica sheet, etc.

[0060] The cooking component 100 of this embodiment, when applied to a microwave oven, allows microwaves to be fed in from at least both sides of the cooking cavity. These microwaves work synergistically to cover at least some areas that the other cannot reach, thus increasing the microwave coverage area within the cooking cavity and improving heating uniformity. Simultaneously, the microwave oven can improve heating uniformity without requiring a stirring device. Therefore, without changing the overall size of the microwave oven, it is advantageous to increase the volume of the cooking cavity, i.e., to improve the microwave oven's volumetric efficiency. Furthermore, by coordinating the power and frequency of each magnetron 30, uniform heating of the food on different sides can be achieved. Changing the power and frequency of the first magnetron 40 and the second magnetron 50 is relatively simple and easy to implement.

[0061] In some embodiments, please refer to Figure 2 Multiple microwave induction zones include a first microwave induction zone and a second microwave induction zone.

[0062] It should be noted that the specific positional relationship between the first microwave induction region and the second microwave induction region on the cavity 10a is not limited.

[0063] For example, the perpendicular line from the side containing the first microwave induction region intersects the perpendicular line from the side containing the second microwave induction region. That is, the side containing the first microwave induction region and the side containing the second microwave induction region are adjacent.

[0064] In this way, roughly orthogonal microwaves are formed within the cooking cavity. This has two advantages: firstly, it allows for a more complex electromagnetic field distribution within the cooking cavity, thereby improving the uniformity of the electromagnetic field distribution, reducing microwave blind spots, and enhancing the uniformity of heating; secondly, it can, to some extent, mitigate the problem of excessively strong or weak local energy caused by uneven electromagnetic fields, thus improving the utilization rate of microwave energy and reducing energy loss.

[0065] For example, the first microwave induction region and the second microwave induction region can also be located on opposite sides of the cavity 10a.

[0066] Specifically, the first microwave induction area and the second microwave induction area are located on opposite sides of the cavity 10a along the height direction of the cooking assembly 100, as an example:

[0067] Microwaves fed through the first microwave induction zone and microwaves fed through the second microwave induction zone can enter the food from the top and bottom sides respectively, thus achieving more uniform heating of the food from both the top and bottom sides.

[0068] It should be noted that the height and orientation of the cooking component 100 should be understood based on the position and orientation of the microwave oven in normal use. Specifically, as shown below... Figure 2 As shown in H.

[0069] In some embodiments, please refer to Figure 2 The housing 10 includes a top plate 11 and a bottom plate 12 spaced apart along the height direction of the cooking assembly 100. The plates on the other sides of the housing 10, excluding the top plate 11 and the bottom plate 12, are side plates 13. The microwave feed port 10b of the first microwave inlet area is the first microwave feed port 13a, which is located on the side plate 13. The microwave feed port 10b of the second microwave inlet area is the second microwave feed port 12a, which is located on the top plate 11 or the bottom plate 12.

[0070] In this way, the food can receive microwave radiation in both the top and bottom and radial directions, which helps to improve the overall heating uniformity of the food.

[0071] Here, the top and bottom direction of the food is the same as the height direction of the cooking component 100, and the radial direction of the food refers to the direction perpendicular to the top and bottom direction of the food.

[0072] Furthermore, based on the turntable microwave oven, the food is carried on the turntable, and the turntable rotates and drives the food to rotate, so that all parts of the food in the circumferential direction can be well affected by the microwaves fed in through the first microwave feed port 13a, while the food in the top and bottom direction can be well affected by the microwaves fed in through the second microwave feed port 12a. Thus, the overall heating uniformity of the food is better.

[0073] In some embodiments, please refer to Figure 2 and Figure 3 The number of first microwave feed ports 13a shall not be less than one.

[0074] It is understandable that the side containing the microwave oven door is the front side, and the side opposite it is the rear side. Facing the front of the microwave oven, the side with your left hand is the left side, and the side with your right hand is the right side. The front side panel 13 is the front side panel, the rear side panel 13 is the rear side panel, the left side panel 13 is the left side panel, and the right side panel 13 is the right side panel.

[0075] The first microwave feed port 13a is located on the side plate 13. Generally, the first microwave feed port 13a is located on the left and right side plates. It is understandable that, based on the cuboid structure of the cavity 10a, the areas of the left and right side plates are relatively small.

[0076] In this embodiment, the heating uniformity of the food in the circumferential direction can be improved by setting at least one first microwave feed port 13a. That is, the minimum number of first microwave feed ports 13a set on the side plate 13 does not need to be too large, and the minimum sum of the opening areas of all the first microwave feed ports 13a in the first microwave induction area will not be too large. In this way, even if the first microwave induction area needs to be set on the left and right side plates, it is easy to implement, thereby improving the versatility of the solution; at the same time, after the first microwave induction area is set on the left or right side plate, the proportion of the sum of the opening areas of the microwave feed ports 10b on it to the overall area of ​​the left or right side plate can also be controlled, which is beneficial to improving the structural stability and reliability of the left or right side plate.

[0077] In some embodiments, please refer to Figure 2 and Figure 3 The number of second microwave feed ports 12a shall not be less than four. For example, it can be five, six, etc.

[0078] Specifically, the example is given by having the second microwave feed port 12a located on the base plate 12.

[0079] A plane rectangular coordinate system is set up with a point on the base plate 12 as the center. The second microwave feed port 12a is distributed in each of the four quadrants of the plane rectangular coordinate system. In this way, when the food is placed on the center for heating, it can be subjected to microwave action on the same horizontal plane, which helps to improve the heating uniformity of the food on the same horizontal plane.

[0080] It should be noted that the specific location of the center of the circle is not restricted.

[0081] For example, the center of the circle can be located at the center of the bottom plate 12. During the heating process, the food is generally placed in the central area of ​​the bottom wall of the cooking cavity for heating. The center of the bottom plate 12 is close to the center of the bottom wall of the cooking cavity. This makes it easier for each second microwave feed port 12a to evenly cover the bottom surface of the food.

[0082] For example, in a turntable microwave oven, the center of the circle can also be located on the axis of the motor shaft. This also makes it easier for each of the second microwave feed ports 12a to evenly cover the bottom surface of the food.

[0083] In some embodiments, please refer to Figure 2 and Figure 8 The magnetron 30 corresponding to the first microwave induction region is a first magnetron 40. The first magnetron 40 includes a first antenna cap 41. In the height direction of the cooking assembly 100, the distance between the center of the first antenna cap 41 and the center of the first microwave feed port 13a ranges from 60mm to 80mm. For example, it can be 60mm, 62mm, 64mm, 66mm, 68mm, 70mm, 72mm, 74mm, 76mm, 78mm, 80mm, etc.

[0084] Specifically, the distance between the center of the first antenna cap 41 and the center of the first microwave feed port 13a is as follows: Figure 8 As shown in L.

[0085] This allows the area with the maximum microwave field strength at the first microwave feed port 13a to have a larger output energy, which is beneficial for improving the cooking efficiency of food and improving the uniformity of heating.

[0086] In some embodiments, the first microwave feed port 13a is circular in shape, and the diameter of the first microwave feed port 13a is smaller than the width of the side plate 13, wherein the width of the side plate 13 is the dimension of the side plate 13 in the direction perpendicular to the height of the cooking assembly 100.

[0087] Understandably, the extended surface of the side panel 13 is parallel to the height direction of the cooking component 100. The side panel 13 has a width dimension, a thickness dimension, and a height dimension, with the width dimension being greater than the thickness dimension.

[0088] In this embodiment, the diameter of the first microwave feed port 13a can be increased as much as possible, which is beneficial for microwaves with higher frequencies and longer wavelengths to pass through the first microwave feed port 13a. This helps to improve the heating efficiency of the food; and, with a wider range of adjustable frequency and wavelength of microwaves fed through the first microwave feed port 13a, the proportion of microwaves fed into the cooking cavity through the first microwave feed port 13a can also be adjusted more in coordination between the first magnetron 40 and the second magnetron 50, thereby improving the heating uniformity of the food.

[0089] In some embodiments, please refer to Figure 2 and Figure 3 The first microwave feed port 13a is formed by multiple sides.

[0090] Here, the edge can be a straight line or a curved line. The edge of the first microwave feed port 13a refers to the line between two adjacent vertices along the circumference of the first microwave feed port 13a.

[0091] For example, when the first microwave feed port 13a is fan-shaped, it has three sides, one of which is an arc and the other two are straight lines.

[0092] For example, when the first microwave feed port 13a is fan-shaped, it has four sides, two of which are arcs and the other two are straight lines.

[0093] For example, when the first microwave feed port 13a is rectangular, it has four sides, and all four sides are straight lines.

[0094] The extension length of each side of the first microwave feed port 13a refers to the length dimension after the side is stretched into a straight line. For example, when calculating the extension length based on a curved side, it is necessary to straighten the curved side and then measure it.

[0095] The longest side of the first microwave feed port 13a refers to the side with the longest extension length among all the sides of the first microwave feed port 13a. The shortest side of the first microwave feed port 13a refers to the side with the shortest extension length among all the sides of the first microwave feed port 13a.

[0096] It is understandable that, based on the rectangular shape of the first microwave feed port 13a, its longest side is the long side of the rectangle, and its shortest side is the wide side of the rectangle.

[0097] In some embodiments, the longest side of the first microwave feed port 13a extends less than the width of the side plate 13, but is greater than or equal to 40 mm, wherein the width of the side plate 13 is the dimension of the side plate 13 in the direction perpendicular to the height of the cooking assembly 100.

[0098] This facilitates the opening of the first microwave feed port 13a on the side plate 13, avoiding the problem of the first microwave feed port 13a penetrating one or both sides of the side plate 13 in the width direction, thereby helping the microwaves to be stably and reliably fed into the cooking cavity.

[0099] In some embodiments, the extension length of the shortest side of the first microwave feed port 13a is greater than or equal to 10 mm. This helps to ensure the distance between two adjacent vertices of the first microwave feed port 13a and helps to improve the arcing problem between the two vertices.

[0100] In some embodiments, the second microwave feed port 12a is circular in shape, and the diameter of the second microwave feed port 12a is smaller than the width of the top plate 11 or the bottom plate 12.

[0101] Specifically, the example is given by having the second microwave feed port 12a located on the base plate 12.

[0102] The base plate 12 is roughly rectangular in shape and has a length dimension, a width dimension, and a thickness dimension, with the length dimension > the width dimension > the thickness dimension.

[0103] In this embodiment, the diameter of the largest second microwave feed port 12a can be maximized, which allows microwaves of higher frequencies and longer wavelengths to pass through the largest second microwave feed port 12a. This improves the heating efficiency of the food. Furthermore, the adjustable range of frequency and wavelength of the microwaves fed through the second microwave feed port 12a is larger. With the coordinated control of the first magnetron 40 and the second magnetron 50, the adjustable range of the proportion of microwaves fed into the cooking cavity through the second microwave feed port 12a is also larger, thereby improving the heating uniformity of the food.

[0104] In some embodiments, please refer to Figure 2 and Figure 3 The second microwave feed port 12a is formed by multiple sides.

[0105] The definitions of the sides, the extension length of the sides, the definition of the longest side, and the definition of the shortest side of the second microwave feed port 12a are all understood with reference to the explanation in the first microwave feed port 13a, and will not be repeated here.

[0106] In some embodiments, the longest side of the second microwave feed port 12a extends less than the width of the top plate 11 or the bottom plate 12, but is greater than or equal to 40 mm. This facilitates the opening of the second microwave feed port 12a on the top plate 11 or the bottom plate 12, avoiding the problem of the second microwave feed port 12a penetrating one or both sides of the top plate 11 or the bottom plate 12 in the width direction, thereby helping the microwaves to be stably and reliably fed into the cooking cavity.

[0107] In some embodiments, the extension length of the shortest side of the second microwave feed 12a is greater than or equal to 10 mm. This helps to ensure the distance between two adjacent vertices of the second microwave feed 12a in the circumferential direction, and helps to improve the arcing problem that occurs between the two vertices.

[0108] In some embodiments, please refer to Figure 2 and Figure 3 There are multiple second microwave feed ports 12a, and at least two second microwave feed ports 12a have different diameters or the dimensions of their longest sides.

[0109] In this way, at least two second microwave feed ports 12a can pass microwaves of different frequencies, so that the microwaves generated by the second magnetron 50 can pass through at least two second microwave feed ports 12a respectively, so that the upper surface of the food can also be heated evenly, achieving the effect of uniform cooking.

[0110] In some embodiments, please refer to Figure 2 and Figure 3 The diameter or the length of the longest side of any two second microwave feed ports 12a are different.

[0111] In other words, the diameter or the length of the longest side of all the second microwave feed ports 12a is different. In this way, each second microwave feed port 12a can transmit microwaves of different frequencies, which is beneficial to further achieve a uniform heating effect within the cooking cavity.

[0112] In some embodiments, please refer to Figures 4 to 7 The waveguide 20 corresponding to the second microwave induction area is the second waveguide 60, and the magnetron 30 corresponding to the second microwave induction area is the second magnetron 50. The second waveguide 60 includes a first segment 61 and a second segment 62 arranged along the height direction of the cooking assembly 100.

[0113] The second segment 62 is disposed on the top plate 11 or the bottom plate 12. The length of the second segment 62 is less than the length of the top plate 11 or the bottom plate 12, and the width of the second segment 62 is less than the width of the top plate 11 or the bottom plate 12. This facilitates the assembly of the second segment 62 on the top plate 11 or the bottom plate 12. Specifically, the length of the second segment 62 is approximately 139.6 mm, and the width is approximately 131.2 mm.

[0114] The first sub-segment 61 connects to the second microwave induction region via the second sub-segment 62. The second magnetron 50 is disposed on the first sub-segment 61, and the aperture of the second sub-segment 62 is larger than that of the second sub-segment 62. That is, the first sub-segment 61 is disposed on the second sub-segment 62. The length of the first sub-segment 61 is smaller than the length of the second sub-segment 62, and the width of the first sub-segment 61 is smaller than the width of the second sub-segment 62. This facilitates the assembly of the first sub-segment 61 onto the second sub-segment 62. Specifically, the width of the first sub-segment 61 is approximately 80 mm.

[0115] In this embodiment, the size of the first segment 61 facilitates the stable installation of the second magnetron 50. The first segment 61 is then connected to the second microwave feed port 12a via the second segment 62. The second segment 62 has a larger diameter and covers a larger area of ​​the top plate 11 or bottom plate 12. This allows for the creation of more second microwave feed ports 12a on the top plate 11 or bottom plate 12, thereby improving heating uniformity and heating efficiency.

[0116] In some embodiments, please refer to Figures 4 to 7 The height of the second sub-segment 62 is greater than or equal to 15mm and less than or equal to 43mm. For example, it can be 15mm, 17mm, 19mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 31mm, 33mm, 35mm, 37mm, 39mm, 40mm, 42mm, 43mm, etc. A height within this range is beneficial for generating TE10 waves, with relatively low microwave loss.

[0117] In some embodiments, please refer to Figures 4 to 7 The first sub-segment 61 is located on the side of the second sub-segment 62 away from the box body 10.

[0118] This facilitates the placement of the second antenna cap 51 of the second magnetron 50. The second magnetron 50 does not need to be installed along the height direction of the cooking assembly 100, which helps reduce the size occupied by the second magnetron 50 in the height direction of the cooking assembly 100, thereby improving the volume ratio of the microwave oven.
