[0030] Embodiment 1

[0031] As Figures 1 to 4 shown, an embodiment of the present utility model discloses a cavity assembly 1, including a cavity structure 11, a reflector 12, and a magnetron 13. The reflector 12 covers the outer wall of the cavity structure 11 to form a waveguide 14. The reflector 12 is provided with a waveguide input port 121 communicating with the waveguide 14. The magnetron 13 is connected to the reflector 12. The output end of the magnetron 13 passes through the waveguide input port 121 and extends into the waveguide 14. The cavity structure 11 is provided with a first waveguide output port 111 and a second waveguide output port 112. Both the first waveguide output port 111 and the second waveguide output port 112 communicate with the waveguide 14 and the inner cavity of the cavity structure 11.

[0032] The output end of the magnetron 13 is located in the waveguide 14. The microwave generated by the magnetron 13 is reflected in the waveguide 14. When it is reflected to the first waveguide output port 111 and the second waveguide output port 112, it then enters the inner cavity of the cavity structure 11 through the first waveguide output port 111 and the second waveguide output port 112. The inner cavity of the cavity structure 11 is used to place food ingredients, so as to cook the food ingredients in the inner cavity of the cavity structure 11 evenly.

[0033] The cavity structure 11 is provided with a first waveguide output port 111 and a second waveguide output port 112, that is, there are two microwave output ports on the cavity structure 11. When the microwave energy source emitted by the magnetron 13 enters the waveguide 14, through the dual-waveguide port structure provided on the cavity structure 11, using the phase difference of the dual microwaves, the microwave energy can be reflected and filled into the entire interior of the cavity structure 11, the heat coverage is more uniform, and the food can also be evenly heated in a short time, so as to achieve a better cooking effect, improve the user experience, and solve the problem in the prior art that there is only one waveguide port in the microwave oven, and the microwave generated by the magnetron cannot fully make the microwave energy evenly distributed, and the food cannot be evenly heated.

[0034] In this embodiment, the position of the first waveguide output port 111 is higher than the position of the second waveguide output port 112. The height positions of the first waveguide output port 111 and the second waveguide output port 112 are different, which is more conducive to evenly heating the food materials in the inner cavity of the cavity structure 11.

[0035] In this embodiment, the cavity structure 11 includes a cavity U-plate 113, a cavity back plate 114, a cavity front plate 115 and a cavity top plate 116. The cavity back plate 114 is provided at the rear end of the cavity U-plate 113, the cavity front plate 115 is provided at the front end of the cavity U-plate 113, and the cavity top plate is provided at the top end of the cavity U-plate 113. The cavity back plate 114, the cavity front plate 115 and the cavity top plate 116 are respectively enclosed with the cavity U-plate 113 to form a cavity structure 11 with an inner cavity.

[0036] In this embodiment, the reflecting cover 12 is covered on the right side wall of the cavity U-plate 113. The first waveguide output port 111 and the second waveguide output port 112 are provided on the right side wall of the cavity U-plate 113, and the first waveguide output port 111 is located directly above the second waveguide output port 112. The microwave energy through the first waveguide output port 111 is more inclined to heat the upper part of the food materials in the inner cavity of the cavity structure 11, and the microwave energy through the second waveguide output port 112 is more inclined to heat the lower part of the food materials in the inner cavity of the cavity structure 11.

[0037] As Figure 5 shown, in some embodiments, the reflecting cover 12 is covered on the right side wall and the outer bottom wall of the cavity U-plate 113. The first waveguide output port 111 is provided on the right side wall of the cavity U-plate 113, and the second waveguide output port 112 is provided on the outer bottom wall of the cavity U-plate 113. The first waveguide output port 111 and the second waveguide output port 112 are not on the same side wall. The first waveguide output port 111 is on the right side wall of the cavity U-plate 113, which is more inclined to heat the upper part of the food materials in the inner cavity of the cavity structure 11. The first waveguide output port 111 is on the outer bottom wall of the cavity U-plate 113, which is more inclined to heat the bottom part of the food materials in the inner cavity of the cavity structure 11.

[0038] In this embodiment, the cavity assembly 1 further includes a mounting bracket 15. The mounting bracket 15 is provided with an avoidance hole 151. The reflecting cover 12 has a fixed side wall. The mounting bracket 15 is arranged on the fixed side wall. The avoidance hole 151 corresponds to the waveguide input port 121. The magnetron 13 is connected to the mounting bracket 15. In order to install the magnetron 13 more stably, the mounting bracket 15 is added. First, the mounting bracket 15 is fixed on the fixed side wall of the reflecting cover 12, and then the magnetron 13 is installed on the mounting bracket 15. The output end of the magnetron 13 passes through the avoidance hole 151, the waveguide input port 121 and then extends into the waveguide 14.

[0039] In this embodiment, the cavity assembly 1 includes a turntable mechanism 16. The turntable mechanism 16 includes a rotating disk 161, a roller ring 162, a driving shaft 163 and a turntable motor 164. The roller ring 162 is arranged on the inner bottom wall of the cavity U-plate 113. The rotating disk 161 is rotatably arranged on the roller ring 162. The inner bottom wall of the cavity U-plate 113 is provided with a rotating hole. One end of the driving shaft 163 is connected to the rotating disk 161, and the other end of the driving shaft 163 is connected to the output end of the turntable motor 164. In order to make the food materials in the inner cavity of the cavity structure 11 be heated more evenly, the food materials are driven to rotate by the turntable mechanism 16, so that the food materials in the inner cavity of the cavity structure 11 are in different positions. Specifically, the turntable motor 164 drives the driving shaft 163 to rotate, and then drives the rotating disk 161 to rotate on the roller ring 162. The food materials are placed on the rotating disk 161, so the food materials rotate as the rotating disk 161 rotates.

[0040] In this embodiment, the cavity assembly 1 includes a first mica sheet 171. The first mica sheet 171 is detachably arranged at the first waveguide output port 111 to cover the first waveguide output port 111. The first mica sheet 171 is inserted into the first waveguide output port 111. The first mica sheet 171 can be penetrated by microwaves and can also prevent oil and dirt from splashing onto the magnetron 13, playing a protective role.

[0041] In this embodiment, the cavity assembly 1 includes a second mica sheet 172. The second mica sheet 172 is detachably arranged at the second waveguide output port 112 to cover the second waveguide output port 112. The second mica sheet 172 is inserted into the second waveguide output port 112. The second mica sheet 172 can be penetrated by microwaves and can also prevent oil and dirt from splashing onto the magnetron 13, playing a protective role.

[0044] Specifically, a cavity assembly 1 includes a cavity structure 11, a reflector cover 12 and a magnetron 13.

The reflector cover 12 is provided with a waveguide input port 121 communicating with the waveguide 14. The magnetron 13 is connected to the reflector cover 12. The output end of the magnetron 13 passes through the waveguide input port 121 and extends into the waveguide 14. The cavity structure 11 is provided with a first waveguide output port 111 and a second waveguide output port 112. Both the first waveguide output port 111 and the second waveguide output port 112 are communicated with the waveguide 14 and the inner cavity of the cavity structure 11.

[0046] Specifically, the microwave oven 2 further includes a bottom plate 22. The bottom plate 22 is connected to the bottom of the cavity structure 11 and encloses with the housing 21.

[0047] The output end of the magnetron 13 is located inside the waveguide 14. The microwave generated by the magnetron 13 is reflected inside the waveguide 14. When it is reflected to the first waveguide output port 111 and the second waveguide output port 112, it then enters the inner cavity of the cavity structure 11 through the first waveguide output port 111 and the second waveguide output port 112. The inner cavity of the cavity structure 11 is used to place food ingredients, so as to cook the food ingredients in the inner cavity of the cavity structure 11 evenly.

[0048] The cavity structure 11 is provided with a first waveguide output port 111 and a second waveguide output port 112, that is, there are two microwave output ports on the cavity structure 11. When the microwave energy source emitted by the magnetron 13 enters the waveguide 14, through the double waveguide port structure provided on the cavity structure 11, by using the phase difference of the double microwaves, the microwave energy can be reflected and filled into the entire cavity structure 11, the heat coverage is more uniform, and the food can be evenly heated in a short time, so as to achieve a better cooking effect, improve the user experience, and solve the problem that the existing microwave oven has only one waveguide port, and the microwave generated by the magnetron cannot fully make the microwave energy evenly distributed and the food cannot be evenly heated.
