As shown in FIGS. 1 to 7, according to the embodiment of the present disclosure, a door assembly 10 is proposed. The door assembly 10 includes a first frame 11, a second frame 12, and shielding members 13. The second frame 12 fits the first frame 11, and the second frame 12 is provided with flanges 121 along edges thereof. The flanges 121 are provided with notches 123 at corners of the first frame 11. The flanges 121 shield an outer side of edges of the first frame 11. The shielding members 13 are provided on an outer side of the flanges 121 and detachably fit the flanges 121 to close the notches 123.

In one embodiment, the second frame 12 is formed by cutting and bending a metal plate, and the notches 123 formed by cutting and bending exist at corners of the second frame 12. When the first frame 11 fits the second frame 12, the first frame 11 and the second frame 12 are spaced apart, and a width of the flange 121 is larger than or equal to a distance between the first frame 11 and the second frame 12. Moreover, the flanges 121 shield the outer side of the edges of the first frame 11. The shielding members 13 fit the flanges 121 to close the notches 123 on the flanges 121, and preventing the notches 123 from scratching the user. In addition, there is no need to perform grinding and welding operations when the shielding members 13 close the notches 123 of the flanges 121, which simplifies the manufacturing process of the door assembly 10, so that the manufacturing efficiency of the door assembly 10 is improved, and the manufacturing cost of the door assembly 10 is reduced.

It should be pointed out that the first frame 11 and the second frame 12 are both rectangular structures, and the first frame 11 and the second frame 12 are assembled with each other to form a door structure, which is pivotally connected to a cabinet 20 of a cooking device 100 through connectors. The door structure is opened or closed so that a cooking cavity of the cabinet 20 is opened or closed. In the present application, both corners at the top of the second frame 12 (i.e., a side of the second frame 12 away from a surface on which the cooking device 100 is placed) have the notch 123, and the shielding member 13 is provided at each of the positions of the two notches 123, and effectively preventing the notches 123 from scratching the user.

In addition, an overlapping structure 1212 is provided on the flanges 121 on both sides of the notches 123 respectively, and the overlapping structures 1212 on both sides are overlapped with each other, and ensuring the strength of the body of the second frame 12 at the notches 123 and avoiding deformation positions of the door assembly 10 due to heat and other factors.

It is further understood that as shown in FIGS. 3 to 7, the shielding member 13 includes a first plate-shaped portion 131 and at least one positioning portion 133. The first plate-shaped portion 131 abuts against an outer surface of the flange 121 and closes the notch 123. The positioning portion 133 is arranged on the first plate-shaped portion 131, and the positioning portion 133 fits a positioning hole 1211 on the flange 121. In one embodiment, when the shielding member 13 closes the notch 123 of the second frame 12, the positioning portion 133 of the shielding member 13 first fits the positioning hole 1211 of the flange 121, to realize the positioning of the shielding member 13, and then the first plate-shaped portion 131 abuts against the outer surface of the flange 121, and closing the notch 123. By providing the positioning portion 133, the positioning and installation of the shielding member 13 is realized, so that the first plate-shaped portion 131 can effectively close the notch 123. In addition, the fit of the positioning portion 133 and the positioning hole 1211 enables the shielding member 13 to be quickly installed, which effectively improves the assembly efficiency and and reduces the manufacturing cost of the door assembly 10.

It should be pointed out that the shape of the first plate-shaped portion 131 coincides with the shape of the notch 123. At the same time, a size of the first plate-shaped portion 131 is larger than a size of the notch 123. When the first plate-shaped portion 131 shields the notch 123, a shielding effect of the shielding member 13 on the notch 123 can be effectively ensured. When the shielding member 13 is manufactured, an edge of the first plate-shaped portion 131 is blunted (for example being rounded, etc.), to avoid scratching the user due to the sharp edge of the first plate-shaped portion 131.

In addition, the positioning portion 133 may be provided in plural, and positioning portions 133 are arranged at intervals. The flange 121 is provided with the positioning holes 1211 having the same number as the positioning portions 133. The positioning portions 133 and the positioning holes 1211 are arranged corresponding to each other. The fit of the positioning portions 133 and the positioning holes 1211 further improves the installation accuracy of the shielding member 13 and improves the quality of the door assembly 10.

In addition, in the present application, the positioning portions 133 are positioning posts, which are provided on an end face of the first plate-shaped portion 131 that faces the flange 121. The positioning posts may be integrally formed with the first plate-shaped portion 131, or may be manufactured separately from the first plate-shaped portion 131 before assembly. The positioning posts are inserted into the positioning holes 1211 to realize the positioning and installation of the shielding member 13. The fitting structure of the positioning posts and the positioning holes 1211 is simple, which facilitates assembly and further improves the efficiency of assembly, and further reduces the manufacturing cost.

In other embodiments, the positioning portion 133 is a positioning bracket, which is inserted into the positioning hole 1211, to realize the positioning and installation of the shielding member 13. The positioning bracket is lightweight, and lowering the mass of the door assembly 10, reducing the force at the connection position of the door assembly 10 and the cabinet 20 of the cooking device 100, and ensuring the stability of the connection between the door assembly 10 and the cabinet 20.

Further, as shown in FIGS. 4 to 7, the shielding member 13 further includes a first clamp-fit portion 134, the flange 121 is provided with a second clamp-fit portion 1231, and the first clamp-fit portion 134 and the second clamp-fit portion 1231 fit each other by clamping. In one embodiment, when the shielding member 13 is installed, the positioning portion 133 is inserted into the positioning hole 1211 to realize the positioning of the shielding member 13, and then the first plate-shaped portion 131 abuts against the flange 121. When the first plate-shaped portion 131 abuts against the flange 121, the first clamp-fit portion 134 and the second clamp-fit portion 1231 fit each other, to realize the fixing of the shielding member 13. The fit of the first clamp-fit structure and the second clamp-fit structure enables a rapid assembly of the shielding member 13, so that the assembly efficiency of the shielding member 13 is further improved, the assembly efficiency of the door assembly 10 is further improved, and the manufacturing cost of the door assembly 10 is further reduced.

It should be pointed out that the first clamp-fit structure is provided on the end face of the first plate-shaped portion 131 that faces the flange 121, and is spaced apart from the positioning portion 133. When the shielding member 13 is assembled, the first plate-shaped portion 131 moves in a direction approaching the flange 121, the positioning portion 133 is gradually inserted into the positioning hole 1211, and the first clamp-fit structure contacts and fits the second clamp-fit structure. When the first plate-shaped structure abuts against the flange 121, the first clamp-fit structure and the second clamp-fit structure fit in place, so that the positioning and assembling of the shielding member 13 are performed simultaneously, and the assembling efficiency of the door assembly 10 is further improved.

Further, as shown in FIGS. 4 to 7, the first clamp-fit portion 134 is an elastic clamping joint, the second clamp-fit portion 1231 is a clamping hole communicating with the notch 123, and the elastic clamping joint fits an inner wall of the clamping hole. In one embodiment, as shown in FIG. 7, the elastic clamping joint has a U-shaped structure. One side wall of an open end of the U-shaped structure is connected to the end face of the first plate-shaped portion 131 that faces the flange 121, and the other side wall of the U-shaped structure is suspended. When the shielding member 13 is installed, the first plate-shaped portion 131 moves close to the flange 121, and the positioning portion 133 is gradually inserted into the positioning hole 1211. The suspended side wall of the U-shaped structure abuts against the inner wall of the clamping hole and undergoes elastic deformation. The fit of the positioning portion 133 and the positioning hole 1211 as well as the fit of the elastic clamping joint and the clamping hole realize the positioning, installation and fixing of the shielding member 13. The overall structure is simple and easy to assemble, so that the assembly efficiency is further improved, and reducing the manufacturing cost of the door assembly 10.

In other embodiments, the first clamp-fit portion 134 is a first buckle, and the second clamp-fit portion 1231 is a second buckle. The fit of the first buckle and the second buckle realizes the installation and fixing of the shielding member 13, and the buckle structure has a high fixing strength, which effectively ensures the stability of the assembly of the shielding members 13.

Further, as shown in FIGS. 3 and 4, a side of the flanges 121 that is away from the second frame 12 is provided with folded edges 122 penetrated by the notches 123, and the folded edges 122 and the second frame 12 are both located on the same side of the flanges 121. The second frame 12, the flanges 121 and the folded edges 122 form an installation space, and the first frame 11 is arranged in the installation space. In one embodiment, the second frame 12 and the folded edges 122 are respectively arranged on both sides of the flanges 121; the folded edges 122 and the second frame 12 both extend toward the same side of the flanges 121; and the folded edges 122, the flanges 121, and the second frame 12 jointly form a box-shaped installation space, which communicates to the outside through one side of the folded edges 122. The first frame 11 is arranged in the installation space. The edges of the first frame 11 are arranged along the positions where the folded edges 122 and the flanges 121 are coupled. When the first frame 11 is installed and fixed, the first frame 11 closes an opening of the installation space on the side of the folded edges 122. The first frame 11 constitutes one side face of the door assembly 10, the second frame 12 constitutes the other side face of the door assembly 10, and the flanges 121 define the width of the door assembly 10. By arranging the first frame 11 in the installation space, a concealed installation of the edges of the first frame 11 is realized, which prevents the edges of the first frame 11 from scratching the user and improves the safety of the user during use.

Further, as shown in FIGS. 4, 5, and 7, the shielding member 13 further includes a second plate-shaped portion 132 connected to the first plate-shaped portion 131, and the second plate-shaped portion 132 abuts against the folded edge 122, so that the position where the folded edge 122 is penetrated by the notch 123 is closed. In one embodiment, on both sides of the notch 123, the flanges 121 are provided at the position where the folded edge 122 is penetrated by the notch 123, and each flange 121 is provided with the folded edge 122. When the shielding member 13 is assembled, the shielding member 13 moves close to the flange 121, the positioning portion 133 is inserted into the positioning hole 1211, the first clamp-fit structure fits the second clamp-fit structure, and when the first plate-shaped portion 131 abuts against the flange 121, the second plate-shaped portion 132 abuts against the folded edge 122 and closes the position where the folded edge 122 is penetrated by the notch 123, which further avoids a situation that the notch 123 scratches the user.

It should be noted that an included angle between the folded edge 122 and the flange 121 is a right angle, and an included angle between the second plate-shaped portion 132 and the first plate-shaped portion 131 is also a right angle. The shape of the second plate-shaped portion 132 is consistent with the shape of the notch 123, and the size of the second plate-shaped portion 132 is larger than the size of the notch 123 on the folded edge 122, so that the first plate-shaped portion 131 and the second plate-shaped portion 132 can effectively close the notch 123. In addition, when the shielding member 13 is manufactured, the edge of the second plate-shaped portion 132 is blunted (for example being rounded, etc.), to avoid scratching the user due to the sharp edge of the second plate-shaped portion 132.

Further, the door assembly 10 further includes fasteners (not shown), the folded edges 122 are provided with first holes 1221, and the second plate-shaped portion 132 is provided with second holes 1321. The second holes 1321 and the first holes 1221 are arranged corresponding to each other, and the fasteners pass through the second holes 1321 to fit the first holes 1221 so that the shielding member 13 is fixed.

By providing the fasteners, the shielding member 13 is further fixed, so that the fixing strength of the shielding member 13 is further ensured to achieve the closing effect of the notch 123.

Further, as shown in FIGS. 4 and 5, the number of the first holes 1221 is two, and the two first holes 1221 are separately arranged on both sides of the position where the folded edge 122 is penetrated by the notch 123. The number of the second holes 1321 and the number of fasteners are each consistent with the number of the first holes 1221. In one embodiment, the notch 123 is provided on the flanges 121 at the corner of the second frame 12 and penetrates the folded edges 122. The folded edges 122 are provided with the first holes 1221 on both sides of the notch 123, and the second plate-shaped portion 132 is provided with the second holes 1321 at positions corresponding to the first holes 1221. Through the arrangement of multiple fasteners, a multi-position fixing of the shielding member 13 is realized, and the fixing strength and stability of the shielding member 13 are further increased. Therefore, a situation that the shielding member 13 becomes loose or even falls off is effectively avoided.

In one embodiment, the fasteners are rivets. The rivets pass through the second holes 1321 and are riveted to the first holes 1221 to realize the fixing of the shielding member 13. The connection and fixation method by rivets has high connection strength and good stability. In addition, the assembly is simple and convenient, which can effectively improve the assembly efficiency, and reducing the manufacturing cost of the door assembly 10.
