It should be noted that the glass cover 21 in this example is a transparent glass made of tempered glass, and the state of food in the cooking chamber can be observed when cooking food.

It should be noted that, both end corners of the first end portion 211 are respectively formed with a transition fillet, and the radius r of the transition fillet is configured to be 15mm < r < 35mm to reduce the stress concentration generated at the end corners when the glass cover plate is thermally expanded. In this embodiment, the radius r of the transition fillet is configured to be 15mm to reduce stress concentration generated at the end corner when the glass cover plate 21 is thermally expanded. That is, the glass cover plate 21 is prevented from generating an internal force interacting with the inside thereof when it is thermally expanded, and the glass cover plate 21 is prevented from being exploded due to the internal force. In another embodiment, the transition radius on the first end 211 may also be 35 mm; in another embodiment, the transition radius on the first end 211 may also be 25 mm.

Structure of the metal base 22:

as shown in fig. 2 and 3, and 4 and 6 and 7, the bottom of the clamping groove is in a connected arrangement, and the side of the clamping groove is in a disconnected arrangement. The metal base 22 is provided with a first sheet 221 and a second sheet 222, wherein the first sheet 221 and the second sheet 222 are integrally connected at the bottom of the bottom 2A of the clamping groove, so that the bottom of the clamping groove 2A is integrally arranged, and the side edges of the first sheet 221 and the second sheet 222 are arranged in a breaking way, so that the side parts of the clamping groove 2A are arranged in a breaking way. Specifically, the four edges of the second sheet 222 located in the clamping groove are connected with the first sheet 221, and are disconnected from the first sheet 221; and the second sheet 222 is provided with a pivot seat 24 for pivotally connecting the body. The length of the first sheet 221 in a second direction perpendicular to the first direction is larger than the length of the second sheet 222 in the second direction, and an opening 2C is formed between both adjacent side edges. That is, only one edge of the second sheet 222 in the second direction is connected to the first sheet 221, and the portion of the second sheet 222 shorter than the first sheet 221 in the second direction forms the opening 2C; it should be noted that the second sheet 222 is disposed in the middle of the first sheet 221 in the second direction, and therefore, there are two openings 2C respectively located at two ends of the second sheet 222 in the second direction.

A clamping groove 2A for clamping the first end 211 of the glass cover plate 21 is formed between the first sheet 221 and the second sheet 222; the first end 211 is held in the holding groove 2A; a first gap S1 is preset between the bottom of the clamping groove 2A and the first end 211, the first gap S1 is a gap from the end of the glass cover plate 21 to the bottom of the clamping groove 2A, and the first gap S1 is used for providing a thermal expansion space for the glass cover plate 21 in the first direction, so as to prevent the glass cover plate 21 from being burst due to the metal base 22 being pressed by the glass cover plate 21 after being heated by the barbecue grill 1.

The two side edges of the first sheet 221 in the second direction are provided with bent portions 2211 extending in a direction close to the second sheet 222, the bent portions 2211 are used for forming a slot 2B for engaging the first end 211, a second gap S2 is preset between the bottom of the slot 2B and the first end 211, and the second gap S2 is used for providing a thermal expansion space for the glass cover plate 21 in the second direction, so as to prevent the glass cover plate 21 from being burst due to the fact that the glass cover plate 21 is pressed against the metal base 22 after being heated by the barbecue grill 1.

As shown in fig. 3, the first sheet 221 and the second sheet 222 are disposed apart from each other at the end corner of the metal base 22 corresponding to the transition fillet. I.e. the opening 2C is arranged at the transition round corner of the glass cover plate 21.

It should be noted that, because the length of the glass cover plate 21 in the first direction is greater than the width of the glass cover plate 21 in the second direction, that is, the expansion distance of the glass cover plate 21 in the first direction after being heated is greater than the expansion distance thereof in the second direction; the first gap S1 is filled with an adhesive for bonding the glass cover 21 and the metal base 22, so that the first gap S1 is at least twice the second gap S2, and further, the first gap S1 in this example is 1mm, and the second gap S2 is 0.5 mm. In other embodiments, the sizes of the first gap S1 and the second gap S2 may be modified as required by those skilled in the art.

Structure of pivot seat 24:

as shown in fig. 8, the pivot base 24 includes a connecting sheet 2221 and a pivot member 241, the connecting sheet 2221 is formed by punching and bending the second sheet 222, a plugging hole 2411 for the connecting sheet 2221 to be inserted into is disposed in the pivot member 241, and the connecting sheet 2221 is inserted into the plugging hole 2411 and is tightly connected to the pivot member 241, in this embodiment, the tight connection is through a screw. Moreover, the pivot base 24 further includes a pivot shaft for realizing the turning motion of the lid assembly 2 on the body, and the pivot shaft is integrally disposed on the pivot member 241 and extends toward the second direction. In this embodiment, there are two pivoting seats 24, which are respectively disposed symmetrically in the second direction of the second sheet 222.

Mounting structure of the cover assembly 2:

as shown in fig. 1 to 8, the second sheet 222 is provided with two pivoting seats 24, and when a force is applied to the pivoting seats 24, a tension force for separating the second sheet 222 from the glass cover plate 21 can be generated. Specifically, the pivot seat 24 can transmit the self-gravity of the cover assembly 2 and/or the turning force applied to the cover assembly 2 to the second sheet 222 to move the second sheet in the direction away from the glass cover 21, i.e. when the glass cover 21 is turned over or hung on the body 1, the turning force or the gravity is applied to the second sheet 222 to drive the second sheet 222 away from the glass cover 21, so as to open the clamping groove 2A. In order to prevent the clamping groove 2A from opening to separate the metal base 22 from the glass cover plate 21, the cover assembly 2 further includes at least one fastener 23, specifically two fasteners 23, passing through the first sheet 221, the glass cover plate 21, and the second sheet 222 in sequence and fastening the three, and the fasteners 23 are disposed adjacent to the pivot seat 24 to generate resistance against the tensile force. This proximity is not meant to be close or abutting, but rather means that the fastener 23 is located in the vicinity of the pivot 24, which would reduce the effectiveness of preventing the clamping groove 2A from opening if the distance between the two is too great.

As shown in fig. 6 and 7, the metal base is provided with a clamping groove 2A and a clamping groove 2B, and the first sheet 221 and the second sheet 222 are provided with through holes K2 for the fasteners 23 to pass through; the glass cover plate 21 comprises a main body part and a first end part 211 which are integrally connected, and a mounting hole K1 for a fastener 23 to pass through is arranged on the first end part 211; when mounting, the first end 211 of the glass cover plate 21 is inserted into the card slot 2B and the clamping slot 2A along the first direction, and the mounting hole K1 is coaxially arranged with the through hole K2, and then the fastener 23 is sequentially inserted through the first sheet 221, the glass cover plate 21, and the second sheet 222 to fasten the second sheet 222 so as not to open.

It should be noted that the fastening member 23 is disposed adjacent to the pivot seat 24, and further, the fastening member 23 in this embodiment is disposed in the first direction of the pivot seat 24 to further prevent the second sheet 222 from expanding.

By implementing the technical scheme, the glass cover plate can effectively prevent the glass cover plate from bursting on the premise of ensuring the connection strength of the metal base and the glass cover plate, and meanwhile, the mouth opening phenomenon is generated at the joint of the metal base and the glass cover plate.

In this embodiment, an adhesive is provided in the holding groove 2A before the insertion of the glass cover 21, but in another embodiment, the glass cover 21 and the metal base 22 may be connected only by the fastening member 23 without providing an adhesive.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
