The combined action of the first microwave source 21 and the second microwave source 31 can improve cooking efficiency, and the food is heated more evenly under the heating of the first microwave source 21 and the second microwave source 31.

[0069] In one embodiment, the first microwave transmission channel 22 is connected to the top of the cooking cavity 11, and the second microwave transmission channel 32 is connected to the bottom of the cooking cavity 11, so that the first microwave source 21 and the second microwave source 31 can heat the food from the top and bottom of the cooking cavity 11 respectively, making the food more evenly heated.

Similarly, a second microwave stirrer can cyclically block or reflect microwaves within the second microwave transmission channel 32, also altering the microwave distribution within the channel.

[0081] Furthermore, in one embodiment, the first microwave source 21 is located horizontally outside the cooking cavity 11. This reduces the space occupied by the first microwave source 21 directly above the cooking cavity 11.

[0082] Furthermore, in one embodiment, the second microwave source 31 is located horizontally outside the cooking cavity 11. This reduces the space occupied by the second microwave source 31 directly below the cooking cavity 11.

[0083] Furthermore, in one embodiment, there are multiple first microwave sources 21 and multiple first microwave transmission channels 22; the multiple first microwave sources 21 and the multiple first microwave transmission channels 22 correspond one-to-one. In this way, multiple first microwave sources 21 can improve cooking efficiency.

Thus, the frame 1 is provided with a first microwave source 21, which can emit microwaves for the user to heat food; the frame 1 is provided with a first microwave transmission channel 22, which connects the first microwave source 21 and the cooking cavity 11. The microwaves emitted by the first microwave source 21 can enter the cooking cavity 11 through the first microwave transmission channel 22, and the microwaves can cook the food in the cooking cavity 11 after entering the cooking cavity 11; the first rotating platform 41 is provided in the top inlet cavity 23, and the frame 1 is provided with a first driving mechanism 43 for driving the first rotating platform 41 to rotate. 43 can drive the first rotating platform 41 to rotate; the first rotating platform 41 has a first through hole 412 for microwaves to pass through, and the first rotating platform 41 can change the microwave distribution state in the first microwave transmission channel 22 during rotation; that is, the rotating first rotating platform 41 can change the distribution state of microwaves entering the cooking cavity 11, so that the microwave distribution state in the cooking cavity 11 can change under the influence of the first rotating platform 41, and the food in the cooking cavity 11 can be cooked by dynamic microwave state, so that the heating state of the food is more even during the cooking process, and avoids local heating of the food for a long time.

[0092] In one embodiment, a rotating stage is provided inside the first microwave transmission channel 22.

[0093] In one embodiment, the first rotating stage 41 is a single piece made of a microwave-impermeable material. In another embodiment, the first rotating stage 41 is a single piece made of a microwave-reflective material.

[0094] In one embodiment, the first predetermined axis is set vertically.

[0095] In one embodiment, at least two first microwave transmission channels 22 converge and communicate with the top of the cooking cavity 11. In this way, microwaves from the at least two first microwave transmission channels 22 can converge and enter the cooking cavity 11 from the top of the cooking cavity 11.

[0096] In one embodiment, the two first microwave transmission channels 22 converge and communicate with the top of the cooking cavity 11. In this way, microwaves from the two first microwave transmission channels 22 can converge and enter the cooking cavity 11 from the top of the cooking cavity 11.

[0097] In one embodiment, the top inlet cavity 23 is cylindrical; the direction in which each microwave transmission channel enters the top inlet cavity 23 is a first direction F1; the first direction F1 is perpendicular to the axis of the top inlet cavity 23. In this way, the space occupied by the first microwave transmission channel 22 in the axial direction of the top inlet cavity 23 is reduced.

[0098] In one embodiment, at least two second microwave transmission channels 32 converge and communicate with the bottom of the cooking cavity 11. In this way, microwaves from the at least two second microwave transmission channels 32 can converge and enter the cooking cavity 11 from the bottom of the cooking cavity 11.

[0099] In one embodiment, the four second microwave transmission channels 32 converge and communicate with the bottom of the cooking cavity 11. In this way, microwaves in the four second microwave transmission channels 32 can converge and enter the cooking cavity 11 from the bottom of the cooking cavity 11.

[0100] In one embodiment, the system further includes a bottom inlet cavity 33 communicating with the bottom of the cooking cavity 11; each of the second microwave transmission channels 32 converges in the bottom inlet cavity 33. Thus, microwaves from each of the second microwave transmission channels 32 first converge into the bottom inlet cavity 33. The bottom inlet cavity 33 is connected to the bottom of the cooking cavity 11, allowing microwaves from the bottom of the cooking cavity 11 to enter the cooking cavity 11, facilitating heating of the food inside the cooking cavity 11 from the bottom.

[0101] In one embodiment, the cooking cavity 11 is located between the top inlet cavity 23 and the bottom inlet cavity 33.

[0102] In one embodiment, two second microwave transmission channels 32 form a first group, and the other two form a second group. The two second microwave transmission channels 32 in the first group converge into the bottom inlet cavity 33 in opposite directions, and the two second microwave transmission channels 32 in the second group converge into the bottom inlet cavity 33 in opposite directions. This opposing convergence direction enhances the energy distribution of microwaves within the bottom inlet cavity 33, and the cross-path design of the microwaves helps improve the interaction between microwaves and food, increasing energy conversion efficiency. Because the second microwave transmission channels 32 in each group converge in opposite directions, microwaves meet and cross-distribute within the bottom inlet cavity 33, effectively covering a wider area and reducing any dead zones in the cooking cavity 11, thereby achieving uniform heating of the food.

[0103] In one embodiment, a baffle is provided between the bottom inlet cavity 33 and the cooking cavity 11; the baffle has multiple rectangular holes. Microwaves can then be output to the cooking cavity 11 through these rectangular holes. Thus, the distribution of microwaves output to the cooking cavity 11 can be controlled through the multiple rectangular holes.

[0104] In one embodiment, the two second microwave transmission channels 32 in the first group converge into the bottom inlet cavity 33 in a second direction F2, and the two second microwave transmission channels 32 in the second group converge into the bottom inlet cavity 33 in a third direction F3; the second direction F2 and the third direction F3 are perpendicular to each other. This allows microwaves in mutually perpendicular directions to enter the bottom inlet cavity 33 and then enter the cooking cavity 11 from different directions. Furthermore, microwaves in mutually perpendicular directions entering the bottom inlet cavity 33 are less likely to encounter dead zones.

[0105] Further, please refer to Figures 1 to 20 In one specific embodiment of the microwave oven provided by the present invention, the first rotating platform 41 includes: a plurality of blades 411; and a first through hole 412 is formed between adjacent blades 411.

[0107] In one embodiment, the blade 411 is a single piece made of a microwave-impermeable material. In another embodiment, the blade 411 is a single piece made of a microwave-reflective material.

[0108] In one embodiment, three blades 411 are arranged sequentially around the outside of a predetermined axis. Thus, when the three blades 411 rotate around the first predetermined axis, they can sequentially block microwaves.

[0109] In one embodiment, the first drive mechanism 43 includes: a columnar body 431 mounted on a frame 1, a ring gear 432 sleeved on the columnar body 431, a first motor 433 mounted on the frame 1 and having a first output shaft 4331, and an output gear 434 mounted on the first output shaft 4331 and meshing with the ring gear 432; each blade 411 is distributed and fixed on the ring gear 432.

[0124] In one embodiment, the air intake channel 52 is a space, chamber, or channel provided on the frame 1.

[0125] In one embodiment, the cooking cavity 11 is a chamber within the frame 1.

[0127] In one embodiment, the airflow after passing through the vent 553 flows from top to bottom into the cooking chamber 11. Thus, the airflow output from the vent 553 can enter the cooking chamber 11 from top to bottom.

[0128] In one embodiment, the airflow within the airflow channel 521 is directed toward the sidewall of the cooking chamber 11. Thus, the gas output from the airflow channel 521 can create a temperature difference on the sidewall of the cooking chamber 11, allowing water vapor to cool and condense on the sidewall.

[0129] In one embodiment, the guide 55 is shaped like a downward-facing trumpet.

[0130] In one embodiment, the top of the guide 55 has a protrusion 552.

[0131] In one embodiment, the surfaces of the protrusion 552 are smoothly connected. In this way, the airflow can be diverted along the surface of the protrusion 552 after encountering it.

[0132] In one embodiment, the viewing hole 551 is formed on top of the protrusion 552.

[0133] In one embodiment, ventilation holes 553 are provided on the protrusions 552 on both sides of the viewing aperture 551.

[0136] In one embodiment, the inclination of the surface of the protrusion 552 (inclination: the angle between the tangent at any point on the surface of the protrusion 552 and the horizontal plane) gradually increases from top to bottom. In this way, when the airflow flows along the surface of the protrusion 552, the airflow is more likely to gradually deviate from the surface of the protrusion 552, reducing the impact of the airflow on the surface of the protrusion 552.

[0137] In one embodiment, it further includes a connecting rib 554 disposed on the guide member 55, the guide member 55 being fixed to the frame 1 by the connecting rib 554.

This four-fold change in airflow direction can buffer the airflow and facilitates guiding the airflow at different locations along the airflow path in different directions, allowing the airflow to apply stress to the guide member 55 from different directions, reducing stress fatigue caused by long-term impact from airflow in the same direction.

[0141] In one embodiment, for any row of ventilation holes 553, the diameters of the plurality of ventilation holes 553 are successively d n =1.5+sin(n), where d n The unit is millimeters, and d n Let n be the diameter of the nth ventilation hole 553, where n is greater than or equal to n. Thus, in a row of ventilation holes 553, the diameters of adjacent ventilation holes 553 will change, making it less likely for adjacent ventilation holes 553 to resonate during exhaust.

[0142] In one embodiment, the downstream of the flow channel 555 is close to the annular folded flange 556, and the flow channel 555 and the annular folded flange 556 are spaced apart.

The air guide 55 has a viewing aperture 551 for the temperature sensor 56 to detect the temperature of the food inside the cooking cavity 11. Thus, the temperature sensor 56 can detect the temperature of the food through the viewing aperture 551.

[0149] In one embodiment, the temperature sensor 56 is an infrared sensor. In another embodiment, the temperature sensor 56 and a camera sensor are present simultaneously, or one of them.

Thus, when water vapor moves upward along the side wall of the condenser tube 54, it easily contacts and condenses against the inner wall of the condensation channel 541, and the condensed water can collect in the water collection space 542.

[0151] In one embodiment, there are multiple condenser tubes 54. Thus, water vapor can be output through multiple condenser tubes 54 respectively.
