The provision of the locking piece 23 can effectively prevent the occurrence of the gaping phenomenon between the metal base 22 and the glass cover 21.

The glass cover plate 21 has a through hole, and the locking member 23 passes through the through hole and fixedly connects the first sheet 221 and the glass cover plate 21. The metal base 22 further includes a second sheet 222, a length of the second sheet 222 in the second direction is greater than a length of the second sheet 222 in the first direction, the first direction and the second direction are two directions perpendicular to each other, and an end of the second sheet 222 in the second direction is bent to form a limiting groove for limiting a moving range of the glass cover plate 21 in the second direction, so as to mount and position the glass cover plate 21. Both ends of the first sheet 221 and the second sheet 222 in the second direction are separately disposed to leave a gap at each of the left and right ends of the first sheet 221 and the second sheet 222, so as to prevent the glass cover plate from bursting after being thermally expanded in the first direction. One end parts of the first and second bodies in the first direction are integrally connected, and the other end parts are separated from each other. The first and second directions are oriented as shown in fig. 2.

The first sheet 221 is formed in a cantilevered structure in the first direction, and the lock piece 23 is disposed at a position capable of preventing the first sheet 221 from deflecting about the second direction. The first sheet 221 and the second sheet 222 are formed with a holding groove 2A for holding the glass cover plate 21 in the first direction, and the glass cover plate 21 is positioned and mounted at a position having a gap with the bottom of the holding groove 2A, the gap being configured to accommodate expansion deformation of the glass cover plate 21 caused by heat.

as shown in fig. 3 to 5, the glass cover 21 includes a main body portion and a mounting portion 211 integrally connected to the main body portion, and the mounting portion 211 is provided with a mounting hole K1 for the locking member 23 to pass through. 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 mounting portion 211 are respectively formed with a transition fillet, and the radius r of the transition fillet is configured to be 15mm to reduce concentrated stress generated at the end corners 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 mounting portion 211 may also be 35 mm; in another embodiment, the transition radius on the mounting portion 211 may also be 25 mm.

Structure of the metal base 22:

as shown in fig. 2, 3, 4, 6 and 7, the metal base 22 has a first sheet 221 and a second sheet 222, the first sheet 221 is located below the glass cover plate, the second sheet 222 is located above the glass cover plate, and edges of the first sheet 221 and the second sheet 222 located at the bottom of the holding groove 2A are integrally connected, and side edges of the two are disconnected from each other. The first sheet 221 is provided with an adapter 24 for pivotal connection to the body. The length of the second sheet 222 in a second direction perpendicular to the first direction is larger than the length of the first sheet 221 in the second direction, and an opening 2C is formed between both adjacent side edges. That is, only the edge of the first sheet 221 in the first direction is attached to the second sheet 222, and the portion of the first sheet 221 shorter than the second sheet 222 in the second direction forms the opening 2C. It should be noted that the first sheet 221 is disposed in the middle of the second sheet 222 in the second direction, and therefore, there are two openings 2C respectively located at two ends of the first sheet 221 in the second direction. The arrangement mode can facilitate the installation of the glass cover plate and can also prevent the glass cover plate from bursting due to thermal expansion.

A clamping groove 2A for clamping the mounting part 211 of the glass cover plate 21 is formed between the first sheet 221 and the second sheet 222; the mounting portion 211 is held in the holding groove 2A; a first gap S1 is preset between the bottom of the clamping groove 2A and the mounting part 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 fact that the glass cover plate 21 extrudes the metal base 22 after being heated by the barbecue grill 1.

The second sheet 222 is provided with a bent portion 2221 extending in a direction close to the first sheet 221 at both side edges in the second direction, the bent portion 2221 is used to form a slot 2B for engaging with the mounting portion 211, a second gap S2 is preset between the bottom of the slot 2B and the mounting portion 211, and the second gap S2 is used to provide 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 metal base 22 being pressed after the glass cover plate 21 is heated by the barbecue grill.

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.

Structure of the adapter 24:

as shown in fig. 8, the adaptor 24 includes a connecting sheet 2211 and a pivot connector 241 fixedly connected to each other, the connecting sheet 2211 is formed by punching and bending the first sheet 221, a plugging hole 2411 for inserting the connecting sheet 2211 is disposed in the pivot connector 241, and the connecting sheet 2211 is inserted into the plugging hole 2411 and is tightly connected to the pivot connector 241, in this embodiment, the tight connection is through a screw. Moreover, the adaptor 24 further includes a pivot shaft for realizing the turning-open motion of the cover assembly 2 on the body 1, and the pivot shaft is integrally disposed on the pivot member 241 and extends toward the second direction. In this embodiment, there are two adapters 24, which are respectively disposed symmetrically in the second direction of the first sheet 221.

Mounting structure of the cover assembly 2:

as shown in fig. 1 to 8, the adapter 24 is disposed on the first sheet 221, and when the cover assembly 2 is turned over or the cover assembly 2 is hung on the body 1 after being turned over, the self-gravity of the cover assembly 2 and/or the turning force applied to the cover assembly 2 is transmitted to the first sheet 221 to generate a tensile force that moves the first sheet 221 in a direction of separating from the glass cover plate 21. That is, when the user turns over the cap assembly 2, the user applies a force to the adaptor 24 through a grip such as a handle, so as to generate a tension force for opening the clamping groove 2A, thereby separating the first sheet 221 from the glass cover plate 21. 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 is further provided with a locking member 23 sequentially passing through and tightly connecting the first sheet 221, the glass cover plate 21 and the second sheet 222, and the locking member 23 is disposed adjacent to the adapter 24 to resist the tensile force, so as to prevent the first sheet 221 and the glass cover plate 21 from separating and further open the clamping groove 2A. This proximity does not mean that it is close or abutting, but means that the locking member 23 is located in the vicinity of the adapter 24, which would reduce the effect of preventing the opening of the holding groove 2A if the distance therebetween is too long.

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 passage of the locking pieces 23; the glass cover plate 21 comprises a main body part and a mounting part 211 which are integrally connected, and a mounting hole K1 for the locking piece 23 to pass through is arranged on the mounting part 211; when mounting, the mounting portion 211 of the glass cover 21 is inserted into the card slot 2B and the clamping slot 2A in the first direction with the mounting hole K1 being coaxially disposed with the through hole K2, and then the locking member 23 is sequentially passed through the first sheet 221, the glass cover 21, and the second sheet 222 to fasten the first sheet 221 so as not to be opened.

It should be noted that the locking member 23 is disposed adjacent to the adapter 24, and further, the locking member 23 in this embodiment is disposed in the first direction of the adapter 24 to further prevent the first sheet 221 from opening.

The above description is only for the specific embodiments of the present invention, but the protection 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 should be covered by the protection scope of the present invention.
