Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0032] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] The utility model provides a door body, which is used for being installed on a cooking device box body of a cooking device and for opening and closing an opening on the cooking device box body for taking in and putting in articles.

[0034] like Figure 1 and Figure 2 As shown, the door body includes a mounting bracket 100, a middle glass 200, an inner glass 400, an outer glass 500, and a stopper 300. The mounting bracket 100 is the mounting and supporting component of the door body. The mounting bracket 100, the inner glass 400, and the outer glass 500 form an installation space. The middle glass 200 is arranged between the inner glass 400 and the outer glass 500 and is located in the installation space. The stopper 300 is arranged in the installation space and is provided with a first stopper slot 310. The edge of the middle glass 200 is snapped into the first stopper slot 310.

[0035] The door body is provided with a three-layer glass structure of middle glass 200, inner glass 400, and outer glass 500, forming an insulating air interlayer between two adjacent glass structures. The provision of the insulating air interlayer can partially isolate the heat from being transferred from the interior of the cooking device to the outside, making it difficult for the heat in the cooking device to be transferred to the outer surface of the door body, thereby reducing the temperature on the outer surface of the door body and improving the anti-scalding performance of the door body. In addition, by providing a limit block 300 within the installation space enclosed by the mounting bracket 100, inner glass 400, and outer glass 500, and providing a first limit slot 310 on the limit block 300, the edge of the middle glass 200 can be snapped into the limit block 300. The snap connection method makes it easy to disassemble and assemble the middle glass 200, reduces the difficulty of disassembling and assembling the door body, makes the door body easy to clean, and improves the user experience.

[0036] The mounting bracket 100 may be an integrally formed frame structure, or may be a frame structure formed by splicing multiple brackets end to end, and the splicing methods include but are not limited to bonding, clamping, connecting with connectors, etc. In some embodiments, continue to refer to Figure 1 As shown, the mounting bracket 100 is a rectangular frame formed by four brackets connected end to end. The four brackets are specifically a first bracket 110, a second bracket 120, a third bracket 130, and a fourth bracket 140. The first bracket 110 and the second bracket 120 are arranged parallel to each other and spaced apart in the second direction. The third bracket 130 and the third bracket 130 are arranged parallel to each other and spaced apart in the third direction. The inner wall surfaces of the first bracket 110, the inner wall surfaces of the second bracket 120, the inner wall surfaces of the third bracket 130, and the inner wall surfaces of the fourth bracket 140, the glass surface of the inner glass 400, and the glass surface of the outer glass 500 enclose a mounting space. Optionally, adjacent brackets are detachably connected by bonding.

[0037] Of course, in other embodiments, the shape of the mounting bracket 100 can be changed as needed, and the number of brackets in the mounting bracket 100 can be increased or decreased as needed. For example, the mounting bracket 100 can be formed by splicing two L-shaped brackets. It should be noted that the brackets are mostly long strips, and the longitudinal cross-sectional shapes of different brackets can be the same or different.

[0038] The limiting block 300 is used to realize the installation and positioning of the centering glass 200. In some embodiments, such as Figure 1 and Figure 3As shown, multiple limit blocks 300 are provided, each positioned at a corner of the installation space. Each limit block 300 is provided with a first limit slot 310. Multiple portions of the edge of the center glass 200 engage with the first limit slots 310 of the multiple limit blocks 300. In some embodiments, the first limit slots 310 are right-angled slots. Alternatively, the limit block 300 may be an integrally formed limit ring with an annular first limit slot 310.

[0039] In a specific embodiment, the mounting bracket 100 is a rectangular frame having four corners. There are four stoppers 300, which are disposed in a one-to-one correspondence at the four corners of the mounting bracket 100. The middle glass 200 is a generally rectangular plate-shaped structure, and the four corners of the middle glass 200 are correspondingly engaged in the first stopper slots 310 of the four stoppers 300. It should be noted that the corners of the middle glass 200 can be right-angled corners located at the intersection of the long side and the end face, or can be corners located in the middle of the long side or short side.

[0040] In some embodiments, the limit block 300 is an elastic block made of elastic material. For example, the limit block 300 can be a silicone block. The limit block 300 has a certain elasticity, which can reduce the difficulty of snap-fitting and assembling the middle glass 200 and the limit block 300.

[0041] In some embodiments, the limiting block 300 includes a first limiting portion and a second limiting portion, a first limiting slot 310 is formed between the first limiting portion and the second limiting portion, and opposite sides of the middle glass 200 are respectively in contact with the first limiting portion and the second limiting portion.

[0042] Furthermore, an inwardly recessed portion is provided on the edge of the middle glass 200, which is inserted into the first limiting slot 310. The limiting block 300 also includes a third limiting portion, which is connected between the first limiting portion and the second limiting portion, and the third limiting portion abuts against the recessed portion.

[0043] In some embodiments, the limiting block 300 includes a first limiting surface 312 and a second limiting surface 313 connected at an angle. The first limiting surface 312 and the second limiting surface 313 respectively abut different sides of the mounting bracket 100. In a specific embodiment, the first limiting surface 312 abuts against the inner side surface of the mounting bracket 100, and the second limiting surface 313 abuts against the top surface of the mounting bracket 100. In one embodiment, the first limiting surface 312 and the second limiting surface 313 are arranged vertically, forming a right-angled groove between the first limiting surface 312 and the second limiting surface 313. A bracket of the mounting bracket 100 is snapped into the right-angled groove. This arrangement allows for quick and accurate positioning, reducing assembly difficulty.

[0044] Furthermore, the stopper 300 is disposed at the corner of two adjacent brackets of the mounting bracket 100, and the first stopper surface 312 is a right-angled surface that simultaneously abuts against the inner side surfaces of the two brackets. This arrangement further improves the assembly stability and efficiency of the stopper 300 and the mounting bracket 100.

[0045] Continue to refer to Figure 3 As shown, a raised structure 311 is provided on the inner wall of the first retaining slot 310, which contacts the glass surface of the middle glass 200. This reduces the contact area between the inner wall of the first retaining slot 310 and the middle glass 200, thereby reducing friction and making it easier to insert and remove the middle glass 200 from the first retaining slot 310. In some embodiments, multiple raised structures 311 are provided on the inner wall of each first retaining slot 310, with the multiple raised structures 311 spaced apart.

[0046] The number of middle glass 200 can be set to multiple layers according to the requirements, for example, Figure 1 and Figure 2 As shown, the door body is provided with two layers of middle glass 200, and a heat-insulating air interlayer is formed between the two adjacent layers of middle glass 200. Figure 2 and Figure 3 As shown, two first limiting slots 310 are provided on the limiting block 300 at intervals along a first direction, and the two layers of middle glass 200 are correspondingly engaged in the two first limiting slots 310. The first direction, the second direction, and the third direction are arranged perpendicularly to each other. Generally, the first direction is the thickness direction of the door body, the second direction is the width direction of the door body, and the third direction is the length direction of the door body.

[0047] Of course, in some embodiments, the number of layers of the middle glass 200 can be increased as needed, for example, three or more layers of middle glass 200 can be set, thereby increasing the number of heat-insulating air interlayers and further improving the anti-scalding performance of the door body; correspondingly, the number of first limit slots 310 on the limit block 300 can also be adaptively increased according to the number of layers of the middle glass 200.

[0048] In some embodiments, the outer glass 500 is roughly a rectangular plate structure, the size of the outer glass 500 is not less than the size of the mounting bracket 100, and the mounting bracket 100 is fixedly connected to the inner glass surface of the outer glass 500 by bonding or other means.

[0049] In some embodiments, the inner glass 400 is a generally rectangular plate-shaped structure. The dimensions of the inner glass 400 are no larger than those of the mounting bracket 100. The inner glass 400 is detachably connected to the inner end surface of the mounting bracket 100. It should be noted that the "inside and outside" mentioned above refer to the cooking device housing. For example, the surface of the mounting bracket 100 closer to the cooking device housing is the inner end surface, while the surface farther from the cooking device is the outer end surface. By detachably connecting the inner glass 400 to the inner end surface of the mounting bracket 100, the inner glass 400 can be easily removed for cleaning.

[0050] In order to achieve the detachable connection between the inner glass 400 and the mounting bracket 100, as shown in FIG. Figure 1 、 Figure 2 and Figure 4 As shown, the mounting bracket 100 is provided with a socket 151, and the inner glass 400 is provided with a plug 410, which is plugged into the socket 151. Of course, in other embodiments, the plug 410 can also be provided on the mounting bracket 100, and the socket 151 can be provided on the inner glass 400.

[0051] In some embodiments, plug 410 includes an insertion end, an intermediate section, and a connection end connected in sequence. The radial dimension of the intermediate section is smaller than that of the insertion end, and the radial dimension of the intermediate section is smaller than that of the connection end, i.e., plug 410 has the characteristic of being thick at both ends and thin in the middle. Socket 151 includes an inner hole, an intermediate hole, and an outer hole connected in sequence. The radial dimension of the intermediate hole is smaller than that of the inner hole, and the radial dimension of the intermediate hole is smaller than that of the outer hole, i.e., socket 151 also has the characteristic of being thick at both ends and thin in the middle. The insertion end can be squeezed through the intermediate hole, so that the insertion end is plugged into the inner hole, the intermediate section is plugged into the intermediate hole, and the connection end is plugged into the outer hole. This arrangement can improve the strength of the plug-in connection, making it difficult for the plug 410 and socket 151 to disengage, thereby reducing the chance of accidental detachment of the inner glass 400.

[0052] In some embodiments, the insertion end of the plug 410 is hemispherical, and correspondingly, the inner hole of the socket 151 is hemispherical.

[0053] In some embodiments, there are multiple jacks 151 and multiple plugs 410 , and the multiple jacks 151 are spaced apart in the circumferential direction of the mounting bracket 100 , and the multiple plugs 410 are spaced apart in the circumferential direction of the inner glass 400 .

[0054] In some other embodiments, the number of the socket 151 and the plug 410 can be one or more, and the socket 151 is located at the same end of the mounting bracket 100. For example, the socket 151 is located on the first bracket 110, and the plug 410 is located on the same end of the inner glass 400. A second retaining slot 121 is provided on the second bracket 120, and the corner of the other end of the inner glass 400 is retained in the second retaining slot 121. This allows one end of the inner glass 400 to engage with one end of the mounting bracket 100, and the other end of the inner glass 400 to plug into the other end of the mounting bracket 100, thereby fully positioning the inner glass 400 and facilitating assembly and disassembly of the inner glass 400. When the user needs to clean the interior of the door, they only need to gently pull the plug 410 on the inner glass 400 from the socket 151 and then remove the corner of the inner glass 400 from the second retaining slot 121. This quick and convenient disassembly process produces little noise, improving the user experience.

[0055] In a specific embodiment, the door body includes two jacks 151 spaced apart along the third direction, both jacks 151 are provided on the first bracket 110, and two plugs 410 spaced apart along the third direction are provided at the end of the inner glass 400 that is opposite to the first bracket 110, and the two plugs 410 are inserted into the two jacks 151 in a one-to-one correspondence; and two second limit slots 121 spaced apart along the third direction are provided on the second bracket 120, and the two corners of the end of the inner glass 400 that is opposite to the second bracket 120 are inserted into the two second limit slots 121 in a one-to-one correspondence.

[0056] In some embodiments, a plug block 150 is protruded from the first bracket 110. The plug block 150 is a block-shaped structure made of a material with a certain degree of elasticity, for example, a rubber block. This allows a certain amount of deformation space for the socket 151, thereby allowing the plug 410 to be squeezed through the middle hole. The number of plug blocks 150 can be set to one or more as needed, and each plug block 150 can be provided with one or more sockets 151 as needed.

[0057] In some parallel embodiments, the plug block 150 is a block structure made of a non-deformable material, so that the shape of the socket 151 remains fixed, and at least the insertion end of the plug 410 is made of an elastic material, for example, the insertion end of the plug 410 is a rubber block, or the entire plug 410 is a rubber head, so that the insertion end of the plug 410 can be squeezed and deformed to pass through the middle hole.

[0058] Continue to refer to Figure 4As shown, avoidance grooves 420 are respectively provided at both ends of the end of the inner glass 400 facing the first bracket 110, one of the avoidance grooves 420 is used to avoid the connection structure between the first bracket 110 and the third bracket 130, and the other avoidance groove 420 is used to avoid the connection structure between the first bracket 110 and the fourth bracket 140.

[0059] Compared with the existing door body, the door body provided by the utility model has the following advantages:

[0060] 1. The user can quickly disassemble and assemble the door body, making it easier to clean the inside of the door body, solving the problem that it is inconvenient for the user to disassemble and assemble the door body for cleaning.

[0061] 2. By setting up a heat-insulating air interlayer inside the door, the heat inside the cooking equipment is not easily transferred to the outer surface of the door. This not only lowers the temperature of the outer surface of the door, preventing users from accidentally touching the outer surface of the door and causing burns, but also improves the thermal insulation effect of the cooking equipment cavity.

[0062] The present invention also provides a cooking device comprising a cooking device housing (not shown) and the aforementioned door. The cooking device housing has an opening, and the door is connected to the cooking device housing and is used to open and close the opening. The cooking device utilizes the aforementioned door, making it easy and fast to remove the door, making it easy to clean the interior, and improving scalding resistance and heat preservation within the cooking device.

[0063] In some embodiments, after the door body is installed on the cooking equipment box body, the second bracket 120 is located above the first bracket 110, that is, the second bracket 120 is the upper bracket, the first bracket 110 is the lower bracket, the upper bracket is rotatably connected to the cooking equipment box body, and the upper bracket can be removed from the cooking equipment box body so that the entire door body can be disassembled and cleaned.

[0064] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
