[0045] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. The same or similar reference numerals in the accompanying drawings represent the same or similar elements or elements with the same or similar functions.

[0046] In addition, the embodiments of the present application described below in conjunction with the drawings are exemplary and are only used to explain the embodiments of the present application and should not be construed as limiting the present application.

[0047] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0048] See also Figure 1 The waveguide component 10 of the embodiment of the present application includes a waveguide tube 12 and an adjusting element 11. The waveguide tube 12 includes an introduction channel 121 and a plurality of outlet channels 122, the plurality of outlet channels 122 are all connected to the introduction channel 121, and the plurality of outlet channels 122 are isolated. The adjusting element 11 is movably arranged on the waveguide tube 12, and the adjusting element 11 can move in the corresponding outlet channel 122 to adjust the amount of microwaves exported by at least one outlet channel 122.

[0049] The waveguide component 10 according to the embodiment of the present application may be applied to a microwave heating appliance 100 , such as a household appliance such as a microwave oven.

[0050] In the waveguide component 10 and the microwave heating appliance 100 of the embodiment of the present application, the adjusting element 11 can adjust the microwave amount of the corresponding outlet channel 122, so that the microwave amount exported by the multiple outlet channels 122 can be adjusted. According to the coordination of the microwave amounts of the multiple outlet channels 122, the food can be heated more evenly.

[0051] Specifically, the waveguide 12 is a component for transmitting microwaves. Microwaves can be transmitted to a predetermined position with minimal loss through the waveguide 12. The waveguide 12 is a hollow metal conduit or a metal-coated tube with a very smooth inner wall. In this embodiment, the waveguide 12 is a multi-branch tubular structure. The material of the waveguide 12 can be stainless steel, copper, copper alloy, aluminum, etc.

[0052] In one embodiment, a waveguide tube 12 may be formed by pressure welding or other methods using metal tubes such as copper tubes and copper alloy tubes. The waveguide tube 12 manufactured in this way includes a metal clad tube consisting of an inner copper layer and an outer copper alloy layer and a hollow area formed inside the metal clad tube, thereby being able to conduct microwaves.

[0053] The waveguide 12 is used to import and export microwaves. The microwaves enter from the import channel 121 and are exported from the export channel 122. The regulating element 11 is a device for adjusting the intensity of the microwaves in the waveguide 12. Microwaves refer to electromagnetic waves with a frequency of 300MHz-3000GHz, which can heat and sterilize objects in some devices.

[0054] It is understandable that the waveguide tube 12 of the embodiment of the present application includes but is not limited to a circular tube, a rectangular tube, a flat rectangular tube or a tube of other shapes. In this article, the waveguide tube 12 is taken as a rectangular tube as an example for description.

[0055] In addition, the number of the outlet channels 122 of the waveguide component 10 may be two or more, and the number of the inlet channels 121 may also be two or more. The waveguide component 10 may be generally T-shaped, T-shaped, Y-shaped, and the like.

[0056] In some embodiments, the number of the introduction channels 121 of the waveguide component 10 may be two, such as Figure 2 The inlet ports of the two inlet channels 121 may face the same direction or may be at a certain angle, such as 20 degrees, 30 degrees, 45 degrees, 90 degrees, 180 degrees, etc.

[0057] In one embodiment, the waveguide component 10 may be of a T-shaped configuration, such as Figure 3 The two outlet channels 122 face opposite directions and are coplanar with the inlet channel 121 .

[0058] In another embodiment, the waveguide component 10 may be a Y-shaped structure, such as Figure 4The outlets 1221 of the two outlet channels 122 are coplanar with the inlet channel 121 at a certain angle.

[0059] It should be pointed out that the ability of the adjusting element 11 to move in the outlet channel 122 means that at least a portion of the adjusting element 11 can be located in the outlet channel 122. For example, the adjusting element 11 can be completely contained in the outlet channel 122, and can move relative to the waveguide 12 to change its position. For another example, the adjusting element 11 can be partially located in the outlet channel 122, and another portion can be located outside the outlet channel 122. The portion of the adjusting element 11 located in the outlet channel 122 can move relative to the waveguide 12 to change its position, and the portion of the adjusting element 11 located outside the outlet channel 122 can be fixed relative to the waveguide 12. For another example, the waveguide 12 can be located outside the waveguide 12, and during the movement of the waveguide 12, at least a portion of the waveguide 12 extends into the outlet channel 122.

[0060] The adjusting element 11 may be formed of a metal material, and the adjusting element 11 may change the amount of microwave extraction by changing the size of the microwave coupling.

[0061] In this embodiment, the outlet channel 122 of the waveguide component 10 includes an outlet 1221, and the directions of the plurality of outlets 1221 are different. The outlet 1221 is where the microwaves are outlet. After the microwaves are outlet from the outlet 1221, the microwaves can act on the object, making the object heated more evenly.

[0062] In some embodiments, the directions of the outlets 1221 may also be the same. Figure 5 , the two outlet channels 122 face the same direction.

[0063] In this embodiment, the adjusting element 11 is movably disposed on the waveguide 12 , and the adjusting element 11 adjusts the microwave quantity of the corresponding outlet channel 122 by adjusting the length of the adjusting element 11 extending into the outlet channel 122 .

[0064] The adjusting element 11 may be in a columnar, sheet-like, ring-like shape or the like, and the adjusting element 11 may be made of metal, liquid tube or other material that can block microwave transmission.

[0065] In one embodiment, the adjusting element 11 may be a metal columnar pin structure, such as Figure 6 The metal columnar pin structure can move vertically up and down in the outlet channel 122 .

[0066] In another embodiment, the adjusting element 11 may be a metal sheet structure, such as Figure 7The metal sheet structure can move vertically up and down in the outlet channel 122, so that compared with the pin structure, the metal sheet structure has a larger blocking area for microwaves and a stronger blocking ability.

[0067] See also Figure 8 In this embodiment, the adjusting element 11 is configured to move back and forth between a first position and a second position relative to the waveguide tube 12. When the adjusting element 11 is in the first position, the length of the adjusting element 11 extending into the outlet channel 122 is a first length. When the adjusting element 11 is in the second position, the length of the adjusting element 11 extending into the outlet channel 122 is a second length. The second length is greater than the first length.

[0068] In this way, by moving the adjusting element 11 back and forth between the first position and the second position in the waveguide 12 , the coupling area between the adjusting element 11 and the microwaves can be changed, thereby changing the blocking amount of the adjusting element 11 to the microwaves.

[0069] Specifically, when the adjusting element 11 is configured to be in the first position relative to the waveguide tube 12, the length of the portion of the adjusting element 11 extending into the outlet channel 122 is the first length, and at this time, the blocking effect of the adjusting element 11 on microwaves is minimal; when the adjusting element 11 is configured to be in the second position relative to the waveguide tube 12, the length of the portion of the adjusting element 11 extending into the outlet channel 122 is the second length, and at this time, the blocking effect of the adjusting element 11 on microwaves is maximal.

[0070] It is understandable that the adjusting element 11 can move between the first position and the second position, so the length of the portion of the adjusting element 11 extending into the outlet channel 122 changes between the first length and the second length. Thus, the adjusting element 11 changes the microwave throughput and realizes the fluctuation of microwave intensity.

[0071] It should be added that, due to the effect of the electric field and the magnetic field in the outlet channel 122, the effect of the adjusting element 11 on the microwave in the outlet channel 122 can be equivalent to an electrical susceptance value. When the length of the adjusting element 11 in the outlet channel 122 is short, the above-mentioned equivalent electrical susceptance value is small, and the microwave blocking effect is small; when the length of the adjusting element 11 in the outlet channel 122 is long, the above-mentioned equivalent electrical susceptance value is large, and the microwave blocking effect is large. Therefore, the microwave amount can be adjusted by adjusting the length of the adjusting element 11 in the outlet channel 122.

[0072] Also, see Fig. 9During the movement of the regulating element 11 between the first position and the second position, the length of the portion of the regulating element 11 extending into the outlet channel 122 changes between the first length and the second length. By changing the length of the regulating element 11 in the outlet channel 122 at a uniform speed or a variable speed and controlling the outlet of the microwave amount through the outlet channel 122, it is possible to achieve proportional adjustment of the microwave output powers of the two ports in the heating cavity 21, thereby forming a similar scanning heating effect inside the heating cavity 21.

[0073] Specifically, the energy distribution on both sides of the heating chamber 21 can be adjusted by fixing the adjusting elements 11 on both sides at different lengths in the outlet channel 122. The lengths of the adjusting elements 11 on both sides can also be changed at a uniform speed, such as Fig.10 As shown, a beam scanning effect is achieved in the heating chamber 21 to achieve more uniform heating. Or the length of the adjusting elements 11 on both sides is changed at a variable speed, such as Fig.11 As shown, the time when the left regulating element 11 is in the outlet channel 122 with a shorter length is longer than the time when the right regulating element 11 is in the outlet channel 122 with a shorter length, and a similar Fig.12 On the contrary, if the time that the left regulating element 11 is in the outlet channel 122 is shorter than the time that the right regulating element 11 is in the outlet channel 122, a similar effect will be obtained. Fig.13 The heating effect.

[0074] It should be pointed out that, in the description of the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot indicate that the adjusting element 11 can only move to two positions, nor can it imply that the first position is more important than the second position, or in other words, the terms "first" and "second" cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0075] In this embodiment, each outlet channel 122 corresponds to an adjustment element 11, and the length of each adjustment element 11 in the corresponding outlet channel 122 is different. Specifically, each outlet channel 122 is equipped with an adjustment element 11, and the positions and lengths of the adjustment elements 11 in the multiple outlet channels 122 are different, resulting in different amounts of microwaves passing through different outlet channels 122. Therefore, the amount of microwaves exported from each outlet 1221 can be different, thereby achieving microwave effects on different parts of the object.

[0076] For example, when the left side of the object needs microwave heating, the microwave amount of the adjustment element 11 to the left outlet 1221 can be large, so that the left side of the object is heated with higher intensity. When all parts of the object need microwave heating, the microwave amount of the adjustment element 11 to each outlet 1221 can be the same, so that the object is completely heated.

[0077] In some embodiments, some outlet channels 122 may not be equipped with the regulating element 11, such as Figure 5 In this embodiment, the regulating element 11 is installed in only one of the two outlet channels 122 , so that the amount of microwaves exported from the outlet 1221 can also be regulated.

[0078] It should be pointed out that in the description of this application, it should be explained that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0079] In this embodiment, the adjusting element 11 may be an adjusting element 11 , and the adjusting element 11 is capable of adjusting the opening of the corresponding outlet channel 122 to adjust the amount of microwaves exported from the corresponding outlet channel 122 .

[0080] Specifically, Fig.14 , Fig.15 The adjusting element 11 is in the form of a sheet, and can change its angle within a certain range in the outlet channel 122, thereby changing the opening of the corresponding outlet channel 122 and adjusting the amount of microwaves passing through the outlet channel 122. When the opening of the outlet channel 122 corresponding to the change in angle of the adjusting element 11 is the largest, the amount of microwaves passing through the outlet channel 122 is the largest; when the opening of the outlet channel 122 corresponding to the change in angle of the adjusting element 11 is the smallest, the amount of microwaves passing through the outlet channel 122 is the smallest.

[0081] See also Fig.16 In this embodiment, each outlet channel corresponds to an adjusting element 11, and the adjusting element 11 can move in the corresponding outlet channel 122 to adjust the opening of the corresponding outlet channel 122. The adjusting element 11 is in a sheet shape and is vertically installed in the outlet channel 122.

[0082] In one embodiment, the adjusting element 11 can adjust the amount of microwaves passing through by changing its own angle in the corresponding outlet channel 122, thereby changing the opening of the outlet channel 122. Fig.17The adjusting element 11 can rotate within the range of 0 to 180 degrees. When the adjusting element 11 rotates at 0 or 180 degrees, the outlet channel 122 opens at the maximum and the amount of microwaves passing through is the maximum. When the adjusting element 11 rotates at 90 degrees, the outlet channel 122 opens at the minimum and the amount of microwaves passing through is the minimum. When the adjusting element 11 rotates between 0 and 90 degrees and between 90 and 180 degrees, the amount of microwaves passing through fluctuates between the maximum and minimum values.

[0083] In another embodiment, the adjusting element 11 can adjust the opening of the corresponding outlet channel 122 by changing the length of the adjusting element 11 extending into the outlet channel 122, thereby changing the amount of microwaves passing through. Fig.18 When the length of the regulating element 11 extending into the outlet channel 122 is the shortest, the opening of the outlet channel 122 is the largest, and the amount of microwaves passing through is the largest; when the length of the regulating element 11 extending into the outlet channel 122 is the longest, the opening of the outlet channel 122 is the smallest, and the amount of microwaves passing through is the smallest.

[0084] It should be pointed out that in the description of the present application, it should be understood that the terms "thickness", "up", "down", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0085] In this embodiment, the regulating element 11 can be movably arranged at the connection between the inlet channel 121 and the plurality of outlet channels 122. During the movement of the regulating element 11, the opening of one outlet channel 122 is reduced, and the opening of at least one other outlet channel 122 is increased. In this way, only one regulating element 11 is needed to adjust the opening of each outlet channel 122 and the amount of microwaves passing therethrough.

[0086] In one embodiment, the above functions can be realized by a ring structure, referring to Fig.19 , Fig. 20 The annular adjusting element 11 is installed at the connection between the inlet channel 121 and the plurality of outlet channels 122. By rotating the annular adjusting element 11, the opening of the outlet channels 121 can be changed.

[0087] Specifically, the annular regulating element 11 is in an irregular ring shape, with one high side and one low side, and the short side is initially close to the inlet channel 121. By rotating the annular regulating element 11, the high side will gradually block one of the outlet channels 122, and the opening will become smaller; the high side portion of the other outlet channel 122 will be reduced, and the opening will become larger. In this way, during the movement of the regulating element 11, the opening of one of the outlet channels 122 is reduced, and the opening of at least one of the other outlet channels 122 is increased.

[0088] See also Fig.21 In this embodiment, the adjusting element 11 can be in a sheet shape, and the number of the outlet channels 122 of the waveguide tube 12 is two. The adjusting element 11 can move at the connection between the two outlet channels 122 and the inlet channel 121. During the movement of the adjusting element 11, the opening of one of the outlet channels 122 decreases, and the opening of the other outlet channel 122 increases.

[0089] It can be understood that in this embodiment, the sheet-shaped regulating element 11 moves at the connection between the two outlet channels 122 and the inlet channel 121. When the regulating element 11 approaches one of the outlet channels 122, the opening of the outlet channel 122 will become smaller, and the opening of the other outlet channel 122 will become larger; conversely, when the regulating element 11 moves away from one of the outlet channels 122, the opening of the outlet channel 122 will become larger, and the opening of the other outlet channel 122 will become smaller. In this way, the microwave amounts exported by the two outlet channels 122 are different at the same time.

[0090] See also Fig. 22 The microwave heating appliance 100 of the embodiment of the present application includes a heating cavity 20 and a waveguide component 10. The heating cavity 20 includes a heating chamber 21. The waveguide component 10 is arranged inside the heating cavity 20, and the outlet channel 122 is used to feed microwaves into the heating chamber 21. In this way, the adjustment element 11 can adjust the microwave amount of the corresponding outlet channel 122, so that the microwave amount of multiple outlet channels 122 can be adjusted. According to the coordination of the microwave amounts of multiple outlet channels 122, the food can be heated more evenly in the heating cavity 20.

[0091] Next, the working principle of the microwave heating appliance 100 of this embodiment is introduced.

[0092] See also Fig.23, the microwave source generates microwaves, which enter the heating cavity 20 through the waveguide component 10 to complete heating. Specifically, in this process, the microwaves enter the heating cavity through the outlet channel 122 of the waveguide component 10, and the adjusting element 11 can adjust the amount of microwaves of the corresponding outlet channel 122, so that the amount of microwaves exported by the multiple outlet channels 122 can be adjusted, and the multiple outlet channels 122 export different amounts of microwaves to achieve a uniform heating process.
