[0039] Please refer to the attached document. Figures 1-5 This application provides an embodiment for use in a microwave oven 100, which is used to heat food.

[0040] Please refer to the attached document. Figures 1-5In the embodiments of this application, the microwave oven 100 includes a microwave oven shell 10, a microwave assembly 20, and a stirring blade 30. The microwave oven shell 10 is provided with an oven cavity 10a and a microwave channel 10b. The oven cavity 10a is used for placing food. The microwave channel 10b communicates with the oven cavity 10a. The microwave assembly 20 is installed on the microwave oven shell 10. The microwave assembly 20 is provided with a magnetron 21. The magnetron 21 is used to generate microwaves. The microwaves generated by the magnetron 21 are conducted to the microwave channel 10b and then to the oven cavity 10a to microwave heat the food. The stirring blade 30 is located near the output end of the microwave channel 10b and above the oven cavity 10a. The stirring blade 30 is rotatably connected to the microwave oven housing 10 and reflects the microwaves output from the output end of the microwave channel 10b during rotation, so that the microwaves can be more evenly distributed in the oven cavity 10a. This ensures the uniformity of the microwaves in the oven cavity 10a, helps to make the microwaves radiate more evenly to all parts of the food, further improves the heating effect, avoids the inability of microwaves to be evenly distributed in the oven cavity 10a, and improves the heating uniformity of the microwave oven 100.

[0041] Please refer to the attached document. Figures 1-2 In the embodiments of this application, the microwave oven housing 10 serves as a supporting component of the microwave oven 100, supporting the microwave assembly 20 and the stirring blade 30. The microwave oven housing 10 is provided with a cavity 10a and a microwave channel 10b. The cavity 10a serves as the internal space of the microwave oven housing 10, and is used for placing food so that the food can be contained within the microwave oven housing 10. The microwave channel 10b connects to the cavity 10a so that microwaves in the microwave channel 10b can flow to the cavity 10a.

[0042] Please refer to the attached document. Figures 1-4 In the embodiments of this application, the microwave component 20 is installed on the microwave oven housing 10. The microwave component 20 is provided with a magnetron 21, which is used to generate microwaves. The microwaves generated by the magnetron 21 are conducted to the microwave channel 10b and then to the oven cavity 10a to microwave heat the food. This allows the microwaves generated by the magnetron 21 to be transferred to the oven cavity 10a, thereby achieving microwave heating of the food in the oven cavity 10a and ensuring that the food is heated to a cooked state.

[0043] Please refer to the attached document. Figures 1-5In the embodiments of this application, the stirring blade 30 is disposed inside the microwave oven housing 10, close to the output end of the microwave channel 10b, and above the oven cavity 10a. The stirring blade 30 is rotatably connected to the microwave oven housing 10 to facilitate adjustment of the position of the stirring blade 30 relative to the microwave oven housing 10. During rotation, the stirring blade 30 reflects the microwaves output from the output end of the microwave channel 10b, so that the microwaves can be more evenly distributed in the oven cavity 10a, ensuring the uniformity of the microwaves in the oven cavity 10a. This helps to make the microwaves radiate more evenly to all parts of the food, further improving the heating effect and avoiding the inability of microwaves to be evenly distributed in the oven cavity 10a, thereby improving the heating uniformity of the microwave oven 100.

[0044] Please refer to the attached document. Figure 5 The microwave oven 100 also includes a motor 40 and a rotating shaft 50. The motor 40 is located on the outside of the microwave oven housing 10, and the rotating shaft 50 is rotatably connected to the microwave oven housing 10 to facilitate adjustment of the position of the rotating shaft 50 relative to the microwave oven housing 10. The fixed end of the motor 40 is connected to the microwave oven housing 10, and the output end of the motor 40 is connected to the rotating shaft 50. The rotating shaft 50 rotates under the drive of the motor 40, thereby realizing the automatic rotation of the rotating shaft 50 to facilitate adjustment of the position of the rotating shaft 50. The stirring blade 30 is connected to the rotating shaft 50 and rotates with the rotation of the rotating shaft 50, so that the stirring blade 30 can achieve automatic rotation through the motor 40 and the rotating shaft 50.

[0045] When the motor 40 is started, the motor 40 drives the stirring blade 30 to rotate via the rotating shaft 50. This facilitates the reflection of microwaves output from the output end of the microwave channel 10b during the rotation of the stirring blade 30, allowing the microwaves to be distributed more evenly within the oven cavity 10a. This ensures the uniformity of the microwaves within the oven cavity 10a, helps to radiate microwaves more evenly to all parts of the food, further improves the heating effect, and avoids the inability of microwaves to be evenly distributed within the oven cavity 10a, thus improving the heating uniformity of the microwave oven 100.

[0046] Please refer to the attached document. Figure 5 The stirring blade 30 is plate-shaped and arranged relative to the output end of the microwave channel 10b. This allows the stirring blade 30 to immediately and evenly distribute the microwaves output from the output end of the microwave channel 10b, ensuring the uniformity of microwaves within the oven cavity 10a. This helps to more evenly radiate microwaves to all parts of the food, further improving the heating effect and preventing microwaves from being unevenly distributed within the oven cavity 10a, thus improving the heating uniformity of the microwave oven 100.

[0047] Please refer to the attached document. Figure 5The stirring plate 30 is a metal stirring plate 30, which can reflect microwaves. The function of the stirring plate 30 is to change the propagation path of microwaves by continuously rotating, so that the microwaves can be more evenly distributed in the furnace cavity 10a, thereby improving the heating effect.

[0048] There are multiple stirring blades 30, which are evenly arranged along the axis of the rotating shaft 50. By arranging multiple stirring blades 30, the stirring efficiency of the stirring blades 30 relative to the microwave is increased, the stirring of the stirring blades 30 relative to the microwave is improved, and the uniformity of the microwave is ensured.

[0049] Please refer to the attached document. Figure 2 The microwave channel 10b is formed by a filter conduit 11, which is part of the microwave oven housing 10. The microwave transmission characteristics are adjusted by changing the cross-sectional area of ​​the waveguide, thereby affecting the standing wave ratio within the oven cavity 10a. This allows for a more uniform distribution of microwaves within the oven cavity 10a, reducing the occurrence of hot and cold spots, and thus improving heating uniformity and efficiency.

[0050] Please refer to the attached document. Figure 2 The end of the filter conduit 11 is provided with an inclined portion 111, which conducts microwaves toward the output end of the microwave channel 10b and the stirring plate 30. The inclined portion 111 accurately directs the microwaves toward the output end of the microwave channel 10b and the stirring plate 30, ensuring the accuracy of microwave output.

[0051] Please refer to the attached document. Figure 2 The inner wall of the oven cavity 10a serves as a reflective sidewall, reflecting microwaves. This allows microwaves to propagate and distribute better within the oven cavity 10a, resulting in more uniform heating of the food.

[0052] Please refer to the attached document. Figure 2 The microwave component 20 is located outside the oven cavity 10a and is connected to the oven cavity 10a through the microwave channel 10b. The microwaves generated by the microwave component 20 are conducted to the microwave channel 10b and then to the oven cavity 10a to microwave heat the food. This allows the microwaves generated by the microwave component 20 to be transferred to the oven cavity 10a, thus ensuring that the food is heated to a cooked state.

[0053] Please refer to the attached document. Figures 2-3 The microwave component 20 also includes a high voltage transformer 22 and a transformer 23. The high voltage transformer 22, the transformer 23 and the magnetron 21 are in the same space and are electrically connected to each other. The high voltage transformer 22 and the transformer 23 cut off or closed the no-load current and load current of the magnetron 21, thereby facilitating the control of the start-up and shutdown states of the magnetron 21.
