[0032] Please refer to the following: Figures 1 to 3 The present invention provides a description of a microwave multi-feed heating device.

There are multiple microwave sources 2 and multiple microwave transmission channels 12, with each microwave source 2 and each microwave transmission channel 12 corresponding one-to-one.

[0036] In one embodiment, the microwave transmission channel 12 is any one of a space, pipe, or groove for microwave transmission.

[0037] In one embodiment, food may be placed inside the cooking cavity, or food may be removed from the cooking cavity.

[0038] Further, please refer to Figures 1 to 3 In one specific embodiment of the microwave multi-feed heating device provided by this utility model, at least two microwave transmission channels 12 converge and communicate with the top of the cooking cavity 11. In this way, microwaves in the at least two microwave transmission channels 12 can converge and enter the cooking cavity 11 from the top of the cooking cavity 11.

[0039] Further, please refer to Figures 1 to 3 In one specific embodiment of the microwave multi-feed heating device provided by this utility model, the two microwave transmission channels 12 converge and communicate with the top of the cooking cavity 11. In this way, the microwaves in the two microwave transmission channels 12 can converge and enter the cooking cavity 11 from the top of the cooking cavity 11.

[0040] Further, please refer to Figures 1 to 3 As a specific embodiment of the microwave multi-feed heating device provided by this utility model, it further includes: a top inlet cavity 13 communicating with the top of the cooking cavity 11; each microwave transmission channel 12 is respectively fed into the top inlet cavity 13. In this way, the microwaves in each microwave transmission channel 12 are first fed into the top inlet cavity 13. The top inlet cavity 13 is communicating with the top of the cooking cavity 11, and the microwaves in the top inlet cavity 13 can enter the cooking cavity 11 from the top of the cooking cavity 11, which facilitates heating the food in the cooking cavity 11 from the top.

[0041] Further, please refer to Figures 1 to 3 In one specific embodiment of the microwave multi-feed heating device provided by this utility model, the top inlet cavity 13 is cylindrical; the direction in which each microwave transmission channel 12 enters the top inlet cavity 13 is a first direction F1; the first direction F1 is perpendicular to the axis of the top inlet cavity 13. In this way, the space occupied by the microwave transmission channels 12 in the axial direction of the top inlet cavity 13 is reduced.

[0042] Further, please refer to Figures 1 to 3 In one specific embodiment of the microwave multi-feed heating device provided by this utility model, at least two microwave transmission channels 12 converge and communicate with the bottom of the cooking cavity 11. In this way, microwaves in the at least two microwave transmission channels 12 can converge and enter the cooking cavity 11 from the bottom of the cooking cavity 11.

[0043] Further, please refer to Figures 1 to 3 In one specific embodiment of the microwave multi-feed heating device provided by this utility model, the four microwave transmission channels 12 converge and connect to the bottom of the cooking cavity 11. In this way, the microwaves in the four microwave transmission channels 12 can converge and enter the cooking cavity 11 from the bottom of the cooking cavity 11.

[0044] Further, please refer to Figures 1 to 3As a specific embodiment of the microwave multi-feed heating device provided by this utility model, it further includes: a bottom inlet cavity 14 communicating with the bottom of the cooking cavity 11; each microwave transmission channel 12 is respectively fed into the bottom inlet cavity 14.

The two microwave transmission channels 12 in the first group converge into the bottom inlet cavity 14 in opposite directions, and the two microwave transmission channels 12 in the second group converge into the bottom inlet cavity 14 in opposite directions. This opposing convergence direction enhances the energy distribution of microwaves within the bottom inlet cavity 14, and the cross-path design of the microwaves helps improve the interaction between microwaves and food, increasing the energy conversion rate. Because the microwave transmission channels 12 in each group converge in opposite directions, the microwaves meet and cross-distribute within the bottom inlet cavity 14, effectively covering a wider area and reducing any dead corners in the cooking cavity 11, thereby achieving uniform heating of the food.

[0047] In one embodiment, a baffle 3 is provided between the bottom inlet cavity 14 and the cooking cavity 11; the baffle 3 has multiple rectangular holes 31. Microwaves can then be output to the cooking cavity 11 through the rectangular holes 31. Thus, the distribution of microwaves output to the cooking cavity 11 can be controlled through the multiple rectangular holes 31.

[0048] Further, please refer to Figures 1 to 3 In one specific embodiment of the microwave multi-feed heating device provided by this utility model, the two microwave transmission channels 12 in the first group converge into the bottom inlet cavity 14 in the direction of the second direction F2, and the two microwave transmission channels 12 in the second group converge into the bottom inlet cavity 14 in the direction of the third direction F3; the second direction F2 and the third direction F3 are set perpendicularly. This allows microwaves in mutually perpendicular directions to enter the bottom inlet cavity 14 and then enter the cooking cavity 11 from different directions. Furthermore, microwaves in mutually perpendicular directions entering the bottom inlet cavity 14 are less likely to encounter dead zones.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
