[0025] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making any creative work are within the scope of protection of the present application.

[0026] See also Figure 1-13 A multifunctional microwave baking tray comprises a tray body 1 and an upper cover 2. The tray body 1 is used for placing food to be baked and heated, and a pot edge 6 is extended outward from the top end of a side wall 4 of the tray body.

[0027] The outer edge of the upper cover 2 is a sheath 3 covering the upper cover 2, and the outer edge contour of the upper cover 2 is adapted to the cross-sectional contour of the inner cavity of the disk body 1; the side wall of the inner cavity of the disk body 1 is provided with a first protrusion 8, and the outer edge of the upper cover 2 is provided with a groove 9 corresponding to the first protrusion 8. The outer edge contour of the upper cover 2 is an axially symmetrical figure such as a circle, a regular polygon, etc., with at least two axes of symmetry, and the cross-sectional contour of the inner cavity of the disk body 1 and the outer edge contour of the matched upper cover 2 have the same shape.

[0028] Therefore, when the groove 9 of the upper cover 2 is aligned with the first protrusion 8, the upper cover 2 can enter the inner cavity of the dish body 1 through the first protrusion 8 and move up and down in the inner cavity of the dish body 1. When the upper cover 2 moves downward to the bottom of the inner cavity of the dish body 1, the baking space formed at this time is smaller and suitable for heating and baking food with small shapes; the upper cover 2 is rotated in the horizontal direction so that the groove 9 of the upper cover 2 is staggered with the first protrusion 8. At this time, the upper cover 2 is directly placed on the first protrusion 8 and cannot enter the inner cavity of the dish body 1. At this time, the baking space formed is larger and suitable for heating and baking food with large shapes.

[0029] A second protrusion 10 is provided at the bottom of the inner cavity of the dish body 1. When the upper cover 2 moves to the bottom of the inner cavity of the dish body 1, the upper cover 2 is placed on the second protrusion 10 to form the minimum space required for baking, thereby avoiding direct contact between the upper cover 2 and the bottom of the inner cavity of the dish body 1, and preventing high-temperature dry burning from damaging the microwave baking tray.

[0030] The outer edge contour of the upper cover 2 and the cross-sectional contour of the inner cavity of the dish body 1 are one of the axially symmetrical figures with at least two axes of symmetry, such as a circle, a regular polygon, etc. In this way, the upper cover 2 and the inner cavity of the dish body 1 have at least two phases that maintain the same matching effect: in one phase, the groove 9 is aligned with the first protrusion 8, so that the upper cover 2 enters the inner cavity of the dish body 1 and covers it; when the upper cover 2 is horizontally rotated to another phase, the groove 9 is staggered with the first protrusion 8, and the upper cover 2 is placed on the first protrusion 8. The upper cover 2 always maintains a good fit and a small gap with the inner cavity of the dish body 1, which can avoid heat loss during baking and heating.

[0031] The outer surfaces of the dish body 1 and the upper cover 2 are provided with a microwave absorbing layer 18, and the food in the inner cavity of the dish body 1 is heated from both the upper and lower directions simultaneously, which is equivalent to the effect of baking with an open flame or electric heating.

[0032] The microwave baking pan in the technical solution further comprises an outer cover 11, and a cover edge 14 is provided on the outer edge of the outer cover 11, and the cover edge 14 is in contact with the pot edge 6. The outer cover 11 is different from the upper cover 2, and does not need to be close to the baked food. When the microwave baking pan is used for steaming or heating, the outer cover 11 is mainly used for heat collection and heat preservation.

[0033] First handles 7 are provided on both sides of the tray body 1, a second handle 16 is provided on the upper surface of the upper cover 2, and a third handle 17 is provided on the upper surface of the outer cover 11 for easy holding.

[0034] In Embodiment 1, the cross-sectional profile of the inner cavity of the disk body 1 and the outer edge profile of the corresponding upper cover 2 are square.

[0035] In Example 2, the cross-sectional profile of the inner cavity of the dish body 1 and the outer edge profile of the matching upper cover 2 are circular; at this time, after entering the inner cavity of the dish body 1, the upper cover 2 can move up and down and can also rotate horizontally; on the side wall of the inner cavity of the dish body 1 between the first protrusion 8 and the second protrusion 10, a third protrusion 19 is also provided, and the third protrusion 19 is multiple and distributed from top to bottom. After moving through the first protrusion 8, the upper cover 2 can continue to move through the lower third protrusion 19 to the second protrusion 10, or the upper cover 2 can be rotated to make the groove 9 and the third protrusion 19 staggered, and the upper cover 2 is placed on the third protrusion 19. Therefore, the upper cover 2 cooperates with the first protrusion 8, the third protrusion 19 and the second protrusion 10 to form a plurality of baking spaces of different sizes, meeting the baking requirements of different foods. In addition, some foods will expand after baking, and the upper cover 2 will be lifted up from the third protrusion 19 under the action of the expanded food until it is blocked by the adjacent third protrusion 19 above or the first protrusion 8 and stops; the upper cover 2 can move appropriately between two adjacent third protrusions 19 above and below, or between the first protrusion 8 and the third protrusion 19 in response to the changes in the shape of the food during baking, thereby maintaining sufficient contact with the food during the baking process and improving the baking effect.

[0036] In addition to common regular polygons, arc regular polygons and regular star polygons can also be used.

[0037] In addition, in Embodiment 3 and Embodiment 4, the cross-sectional contour of the inner cavity of the disk body 1 and the outer edge contour of the corresponding upper cover 2 are both rectangular.

[0038] In Example 3, as shown in the attached Figure 10-11 As shown, the first protrusion 8 is symmetrically arranged on the two short sides of the inner cavity of the rectangular disk body 1 with respect to the short symmetry axis of the rectangular disk body 1, and the center position of the first protrusion 8 is offset relative to the long symmetry axis of the inner cavity of the rectangular disk body 1. In this way, after the upper cover 2 is horizontally rotated 180°, the groove 9 of the upper cover 2 is staggered with the first protrusion 8, and the upper cover 2 can be placed on the first protrusion 8.

[0039] In Example 4, as shown in the attached Figure 12-13 As shown, two first protrusions 8 are respectively provided on the short sides of the inner cavity of the rectangular disk body 1, and the four first protrusions 8 are in the same horizontal plane, but the spacing between the two first protrusions on one side is larger than that on the other side. The grooves 9 are opened corresponding to the four first protrusions 8, so that the upper cover 2 can pass over the first protrusions 8 and be placed on the lower part of the rectangular disk body 1. After the upper cover 2 is horizontally rotated 180°, the grooves 9 can still be staggered with the first protrusions 8, and the upper cover 2 can be placed on the first protrusions 8.

[0040] In Examples 1, 2, 3 and 4, the first protrusion 8 and the third protrusion 19 are bumps facing the inner cavity of the disk body 1, and the second protrusion 10 is a step facing the inner cavity of the disk body 1 and provided circumferentially at the bottom of the side wall of the disk body 1.

[0041] Since the pan body 1, the upper cover 2 and the outer cover 11 are all made of metal materials, the outer edge of the upper cover 2 is a sheath 3 covering the edge of the upper cover 2, and at least one of the pot edge 6 or the cover edge 14 is covered with an insulating protection ring 15, which can prevent the upper cover 2 and the pan body 1, the outer cover 11 and the pan body 1 from contacting and causing ignition. In Examples 1, 2, 3 and 4, the insulating protection ring 15 is covered on the pot edge 6. The above-mentioned sheath 3 and insulating protection ring 15 are both non-metallic insulating materials, preferably silicone rubber or plastic.
