The door body 2210 may be movably disposed in various manners, for example, the door body 2210 is abutted against and separated from the front plate 2140 in a rotating manner, or the door body 2210 may be designed to be in a form capable of being pushed and pulled reciprocally, the opening and closing of the opening 2102 are achieved by the push-pull door body 2210, for example, the oven 2000 includes a slide rail 2220, the door body 2210 is capable of being pushed and pulled by the slide rail 2220, a fixing portion of the slide rail 2220 is fixedly disposed, a specific position to be fixed is not limited, a movable portion of the slide rail 2220 is fixed to the door body 2210, and a movable portion of the slide rail 2220 is movably (slidably) connected with respect to the fixing portion of the slide rail 2220, so that the installation of the door body 2210 is achieved by the slide rail 2220 and the push-pull of the door body 2210 is enabled.

In order to roast food materials, an upper burner 2310 is mounted on the top plate 2120, the upper burner 2310 burns downward to roast food materials from top to bottom, and generally, lower burners 2320 are mounted on the side plates 2130 on the left and right sides, respectively, and the lower burners 2320 roast food materials from bottom to top. The upper burner 2310 and the lower burner 2320 are composed of an air inlet 2313 and a fire outlet 2314 communicated with the air inlet 2313, and the fuel gas is sprayed from the fire outlet 2314 to be ignited to form flame after being introduced into the air inlet 2313, so that the high temperature is formed to realize the baking of the food.

Taking the case where the upper burner 2310 is mounted to the top plate 2120 as an example, there is contact between the upper burner 2310 and the top plate 2120, that is, there is a difference in the rate of change of temperature between the top plate 2120 and the upper burner 2310 due to a difference in the rate of change of temperature between the temperature of the oven 2000 in the heating stage where the oven 2000 starts to operate and the cooling stage where the oven 2000 stops operating, and there is a difference in the amount of deformation due to expansion with heat and contraction with cold, the top plate 2120 collides with the upper burner 2310 to generate abnormal noise, in order to solve this problem, in the present embodiment, the problem is solved by providing the boss 2123. Specifically, the top plate 2120 has a peripheral portion 2122 connected to the upper burner 2310, and the peripheral portion 2122 surrounds the mounting hole 2121, and it is understood that the so-called peripheral portion 2122 is a portion that is close to the mounting hole 2121 and needs to be connected to the upper burner 2310. When the upper burner 2310 is mounted to the top plate 2120, the upper burner 2310 is brought into contact with the peripheral portion 2122, and then the upper burner 2310 is connected to the peripheral portion 2122, so that the upper burner 2310 is mounted to the top plate 2120, and at this time, the upper burner 2310 covers the mounting hole 2121, and a portion corresponding to the upper burner 2310 is exposed to the mounting hole 2121, so that combustion can be performed toward the accommodation chamber 2101. It will be appreciated that there are a variety of ways in which the connection between the upper burner 2310 and the peripheral portion 2122 can be accomplished so long as the upper burner 2310 and the peripheral portion 2122 are secured, such as by welding, screw connection, and the like.

The boss 2123 is provided on the peripheral portion 2122, and when the upper burner 2310 is connected to the peripheral portion 2122, the upper burner 2310 and the boss 2123 come into contact with each other to abut on the boss 2123, that is, the boss 2123 is located between the upper burner 2310 and the peripheral portion 2122. Generally, the portion of the upper burner 2310 connected to the peripheral portion 2122 is relatively flat, the peripheral portion 2122 is also relatively flat, when the protruding portion 2123 is provided, the protruding portion 2123 forms a space, the upper burner 2310 is not in complete contact with the peripheral portion 2122 and is attached together, but a gap cavity 2400 is formed between the upper burner 2310 and the peripheral portion 2122, so that no contact is formed, the contact area between the upper burner 2310 and the peripheral portion 2122 is reduced, the peripheral portion 2122 and the upper burner 2310 expand with heat and contract with cold to deform during the heating and cooling phases of the oven 2000, and the existence of the gap cavity 2400 provides a space for deformation, so that collision between the peripheral portion 2122 and the upper burner 2310 is avoided, and abnormal sound is avoided.

In some embodiments of the utility model, as shown in connection with fig. 6, the raised portion 2123 is designed to extend along the peripheral portion 2122.

Specifically, since the upper burner 2310 needs to be mounted to the top plate 2120 to cover the mounting hole 2121, the upper burner 2310 needs to be in contact with and connected to the peripheral portion 2122 along the circumferential direction of the mounting hole 2121, thereby ensuring stable connection of the upper burner 2310, and on the basis, the boss 2123 is designed to extend along the peripheral portion 2122, i.e., along the circumferential direction of the mounting hole 2121, so that the boss 2123 has a certain length along the circumferential direction of the mounting hole 2121, and thus the number of bosses 2123 can be reduced, facilitating the arrangement of the boss 2123, thereby ensuring that the contact area between the upper burner 2310 and the peripheral portion 2122 is reduced in the circumferential direction of the mounting hole 2121, and avoiding occurrence of abnormal sounds to the maximum extent.

Alternatively, in some embodiments of the present utility model, as shown in fig. 6, the protruding portion 2123 is annular along the circumferential direction of the mounting hole 2121, and it is understood that the annular shape is a hollow structure, and the middle portion is missing and the remaining peripheral portion is regarded as annular, which may be a circular ring, a square ring, or other shapes. By designing the protruding portion 2123 in a ring shape, the number of protruding portions 2123 is regarded as one, and the arrangement of the protruding portion 2123 is facilitated. Further, when the upper burner 2310 is connected to the peripheral portion 2122, the upper burner 2310 is abutted against the boss 2123 in the circumferential direction of the mounting hole 2121, and the abutment surface between the upper burner 2310 and the boss 2123 is also annular, so that the sealing performance can be improved. The upper burner 2310 and the protruding portion 2123 can be further coated with sealant, and the sealant is continuous and uninterrupted along the circumference of the mounting hole 2121, so that the sealing effect can be further improved, and smoke in the accommodating cavity 2101 is not easy to leak out.

In some embodiments of the present utility model, the protruding portion 2123 is integrally formed with the peripheral portion 2122, so that the structural strength of the peripheral portion 2122 can be improved, and generation of abnormal noise can be further suppressed.

Specifically, there are various ways in which the boss 2123 is disposed on the peripheral portion 2122, for example, the boss 2123 is welded to the peripheral portion 2122, or the boss 2123 is clamped to the peripheral portion 2122, and it will be appreciated that although the foregoing various ways can implement disposing the boss 2123 on the peripheral portion 2122, the process is complicated and the boss 2123 is at risk of loosening. In this embodiment, the protruding portion 2123 and the peripheral portion 2122 are integrally formed, that is, the protruding portion 2123 and the peripheral portion 2122 are integrally formed, and no obvious connection trace is generated between them, for example, the protruding portion 2122 and the peripheral portion 2123 have high structural strength by machining, casting, stamping, and the like, so that the peripheral portion 2122 is prevented from being greatly deformed during temperature rise and temperature drop, and abnormal noise is further suppressed. It will be appreciated that a portion of top plate 2120 is considered to be peripheral portion 2122 and that top plate 2120 may be integrally formed, such as by stamping top plate 2120 as a sheet metal part.

In addition, the top plate 2120 is disposed around the accommodating chamber 2101, and when the upper burner 2310 is mounted on the top plate 2120, the top plate 2120 supports the upper burner 2310 through the peripheral portion 2122, the weight of the upper burner 2310 is pressed on the peripheral portion 2122, and the peripheral portion 2122 and the protruding portion 2123 are integrally formed, so that deformation of the peripheral portion 2122 due to the weight of the upper burner 2310 can be prevented, and the upper burner 2310 can be mounted more stably and reliably.

Further, in some embodiments of the present utility model, as shown in fig. 7, the protruding portion 2123 is formed by bending from the peripheral portion 2122, and the peripheral portion 2122 is bent away from the mounting hole 2121, so that the manufacturing difficulty of the protruding portion 2123 is reduced.

Specifically, a plate is used to make the top plate 2120, for example, the plate is a metal plate, and has a certain ductility, the middle portion of the plate is punched with a mounting hole 2121, then a portion of the plate close to the mounting hole 2121 is bent to form a protruding portion 2123, the remaining portion of the plate is regarded as the top plate 2120, so that the top plate 2120 and the protruding portion 2123 are integrally formed, the structural strength is improved, the protruding portion 2123 is formed through a bending process, the difficulty in setting the protruding portion 2123 is reduced, and the manufacture of the whole top plate 2120 is facilitated.

In some embodiments of the present utility model, as shown in fig. 7, the width of the boss 2123 needs to have a reasonable range to ensure that the structural strength of the peripheral portion 2122 is enhanced and that a large contact area with the upper burner 2310 is avoided, so that the width of the boss 2123 is designed to be 2mm to 4mm, for example, the width of the boss 2123 is 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc., and it is understood that the width of the boss 2123 is referenced to the radial direction of the mounting hole 2121.

In some embodiments of the present utility model, as shown in connection with fig. 6 to 8, the peripheral portion 2122 and the upper burner 2310 have a first position 2124, the peripheral portion 2122 and the upper burner 2310 are connected by the first position 2124, and the first position 2124 is provided at a side of the boss 2123 facing away from the mounting hole 2121 in a radial direction of the mounting hole 2121, thus preventing an edge of the upper burner 2310 from being warped.

Specifically, a so-called first position 2124, that is, a position where the peripheral portion 2122 and the upper burner 2310 are connected, the first position 2124 is provided on a side of the boss 2123 facing away from the mounting hole 2121, that is, the first position 2124 is farther from the mounting hole 2121 than the boss 2123, the first position 2124 is closer to an edge of the upper burner 2310 than the boss 2123, and when the first position 2124 of the peripheral portion 2122 and the first position 2124 of the upper burner 2310 are connected, a constraint is formed between the peripheral portion 2122 and the upper burner 2310 at the first position 2124, whereby fixation is achieved, and since the first position 2124 is closer to the edge of the upper burner 2310 than the boss 2123, a cocking phenomenon occurring between the upper burner 2310 and the boss 2123 due to abutment can be suppressed. It will be appreciated that if the first position 2124 is disposed on the side of the boss 2123 adjacent to the mounting hole 2121, i.e., the first position 2124 is closer to the mounting hole 2121 and the boss 2123 is closer to the edge of the upper burner 2310, when the upper burner 2310 is connected to the periphery at the first position 2124, the upper burner 2310 abuts against the boss 2123, and the upper burner 2310 is tilted by the reaction force of the boss 2123, which affects the assembly.
