Specifically, the microwave component is arranged on the main body, the microwave component can generate and propagate microwaves, and the microwave component includes a waveguide, and the waveguide is used to propagate microwaves. It can be understood that in the prior art, the waveguide is usually arranged on the side wall of the microwave oven so that the waveguide can radiate microwaves into the cavity of the microwave oven, but this will increase the width of the microwave oven, which is not conducive to the miniaturization design of the product.

The microwave radiation device has a plurality of fins, and the fins are used to radiate microwaves. Specifically, the microwaves can be radiated toward the cooking cavity along the extension direction of the fins, and there is an angle between the axis of the fins and the axis of the waveguide. In this way, the propagation direction of the microwaves can be changed during the propagation of the microwaves through the cooperation of the waveguide and the microwave radiation device, so that the microwaves can be radiated into the cooking cavity. In this way, the propagation of microwaves can be achieved without arranging the waveguide on the side wall of the cooking cavity, so that the waveguide and the microwave radiation device can be more compactly concentrated on the main body, reducing the installation space occupied by the waveguide and the microwave radiation device, which is conducive to the miniaturized design of the cooking appliance.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0069] Refer to the following Figures 1 to 21 A cooking appliance 100 is described according to some embodiments of the present invention.
[0070] In one embodiment according to the present application, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, the present invention proposes a cooking utensil 100, comprising: a main body 110, comprising a cooking cavity 111; a microwave component 120, arranged on the main body 110, the microwave component 120 comprising a waveguide 121; a microwave radiation device 130, arranged on the main body 110, the microwave radiation device 130 having a feed port 131, the waveguide 121 transmits microwaves to the microwave radiation device 130 through the feed port 131, the microwave radiation device 130 comprises a plurality of fins 132, the fins 132 are used to radiate microwaves into the cooking cavity 111, and an angle is formed between the axis of the waveguide 121 and the axis of the fin 132.
[0071] The cooking utensil 100 proposed in the present application includes a main body 110, and the main body 110 includes a cooking cavity 111, and the cooking cavity 111 is used to accommodate food. The cooking utensil 100 can cook the food in the cooking cavity 111. The cooking utensil 100 includes a microwave component 120, and the food in the cooking cavity 111 can be heated by microwaves through the microwave component 120. Specifically, the microwave component 120 is arranged on the main body 110, and the microwave component 120 can generate and propagate microwaves. The microwave component 120 includes a waveguide 121, and the waveguide 121 is used to propagate microwaves. It is understandable that in the prior art, the waveguide 121 is usually arranged on the side wall of the microwave oven so that the waveguide 121 can radiate microwaves into the cavity of the microwave oven, but this will increase the width of the microwave oven, which is not conducive to the miniaturization design of the product. In order to avoid the above problems, the present application further provides a microwave radiation device 130 capable of changing the propagation direction of microwaves in the cooking device 100, so that the waveguide 121 does not need to be connected to the side wall of the cooking cavity 111, and microwaves can be radiated into the cooking cavity 111 through the cooperation of the waveguide 121 and the microwave radiation device 130, and the microwave assembly 120 and the microwave radiation device 130 can be more compactly arranged in the main body 110, reducing the installation space occupied by the microwave assembly 120 and the microwave radiation device 130. The microwave radiation device 130 is specifically defined below.
[0072] Furthermore, the microwave radiation device 130 has a feed port 131, and the waveguide 121 is connected to the feed port 131. The waveguide 121 can transmit microwaves to the microwave radiation device 130 through the feed port 131. The microwave radiation device 130 has a plurality of fins 132, and the fins 132 are used to radiate microwaves. Specifically, the microwaves can be radiated toward the cooking cavity 111 along the extension direction of the fins 132, and there is an angle between the axis of the fins 132 and the axis of the waveguide 121. In this way, the propagation direction of the microwaves can be changed during the propagation of the microwaves through the cooperation of the waveguide 121 and the microwave radiation device 130, so that the microwaves can be radiated into the cooking cavity 111. Figure 4 As shown in the figure, the axis of the waveguide 121 and the axis of the fin 132 have an angle E. In this way, the propagation of microwaves can be achieved without arranging the waveguide 121 on the side wall of the cooking cavity 111, so that the waveguide 121 and the microwave radiation device 130 can be more compactly concentrated on the main body 110, reducing the installation space occupied by the waveguide 121 and the microwave radiation device 130, which is conducive to the miniaturization design of the cooking device 100.
[0073] In a possible embodiment, the axis of the fin 132 is perpendicular to the bottom wall of the cooking cavity 111, the axis of the waveguide 121 tends to be parallel to the bottom wall of the cooking cavity 111, and the angle between the axis of the waveguide 121 and the axis of the fin 132 is about 90°.
[0074] In some embodiments, optionally, Figure 2 , Figure 4 , Fig. 9 , Fig.11 , Fig.13 , Fig.15 , Fig.18 , Fig.19 and Fig.21 As shown, the microwave radiation device 130 includes: a surface wave generating component 133, including a fin 132; a microwave bottom plate 137, including a mounting groove 138, the surface wave generating component 133 is located in the mounting groove 138, and the feed port 131 is arranged at the connection between the side wall of the mounting groove 138 and the bottom wall of the mounting groove 138.
[0075] In this embodiment, the structure of the microwave radiation device 130 is further defined. The microwave radiation device 130 includes a surface wave generating component 133 and a microwave bottom plate 137. The surface wave generating component 133 is used to radiate microwaves. The microwave bottom plate 137 is used to install and fix the surface wave generating component 133 and transmit the microwaves of the waveguide 121 to the surface wave generating component 133. Specifically, the microwave bottom plate 137 includes a receiving groove, and the surface wave generating component 133 includes fins 132. Specifically, the surface wave generating component 133 includes a surface wave generating plate 134, and the surface wave generating plate 134 is installed in the receiving groove, and the fins 132 are all arranged on the surface wave generating plate 134. The feed port 131 is arranged at the connection between the side wall of the installation groove 138 and the bottom wall of the installation groove 138, and at least part of the feed port 131 is arranged on the side wall of the accommodating groove. The waveguide 121 is connected to the feed port 131, and the waveguide 121 transmits microwaves to the fins 132 through the feed port 131, and the fins 132 radiate microwaves into the cooking cavity 111.
[0076] Compared with setting the feed port 131 on the bottom wall of the accommodating groove, by setting the feed port 131 at the connection between the side wall of the mounting groove 138 and the bottom wall of the mounting groove 138, and making at least part of the feed port 131 set on the side wall of the accommodating groove, the waveguide 121 and the microwave bottom plate 137 can be close to the same horizontal plane, avoiding excessive height difference between the waveguide 121 and the microwave bottom plate 137, further reducing the installation space occupied by the waveguide 121 and the microwave radiation device 130, avoiding increasing the thickness of the cooking utensil 100, and further reducing the volume of the cooking utensil 100.
[0077] In some embodiments, optionally, Fig. 9 and Fig.11 As shown, the microwave radiation device 130 also includes: a microwave shielding plate 139, which is installed on the side of the microwave bottom plate 137 facing the bottom wall of the cooking cavity 111, and the microwave shielding plate 139 is located on the peripheral side of the surface wave generating component 133. The microwave shielding plate 139 is used to prevent microwaves from propagating in a direction away from the surface wave generating component 133.
[0078] In this embodiment, the microwave radiation device 130 is further defined. The microwave radiation device 130 also includes a microwave shielding plate 139, which is used to converge microwaves on the surface wave generating element. Specifically, the microwave shielding plate 139 is a metal frame structure, and the microwave shielding plate 139 is installed on the side of the microwave bottom plate 137 facing the cooking cavity 111, and the microwave shielding plate 139 is located on the peripheral side of the surface wave generating component 133. The waveguide 121 transmits microwaves to the fins 132 on the surface wave generating component 133 through the feed port 131. If the peripheral side of the surface wave generating component 133 is not provided with a structure capable of shielding microwaves, then part of the microwaves will diverge to the peripheral side of the surface wave generating component 133, thereby reducing the efficiency of microwave heating. In order to avoid microwave divergence, the present application provides a microwave shielding plate 139 for shielding microwaves in the microwave radiation device 130. By arranging the microwave shielding plate 139 on the peripheral side of the surface wave generating component 133, the microwave shielding plate 139 can prevent the microwaves from propagating in a direction away from the surface wave generating component 133, thereby concentrating the microwaves on the surface wave generating component 133, reducing microwave divergence and improving cooking efficiency.

[0081] Specifically, all fins 132 are divided into a plurality of fin groups, and the plurality of fin groups are arranged on the surface wave generating plate 134, and any fin group of the plurality of fin groups includes a plurality of fins 132.
