[0055] In a normal state, the first connecting member 11 and the second connecting member 12 are fixedly arranged at intervals on both sides of the door body 13. After the second connecting member 12 is connected to the hinge 30, the first door assembly 10 is connected or fixed to the microwave oven cavity.

[0056] It should be noted that the first connecting member 11 and the second connecting member 12 are both metal plates or metal rods with high strength, and their purpose is to connect the oven door assembly 100 to the cavity of the microwave oven or to connect the first door assembly 10 to the second door assembly 20.

[0057] See also Figure 3 In some embodiments, the second door assembly 20 includes a cover plate 22 , which is fixedly connected to a side of the third connecting member 21 facing away from the first door assembly 10 .

[0058] It can be understood that the third connecting member 21 is used to connect with the second connecting member 12 or the first connecting member 11 to connect the second door assembly 20 to the first door assembly 10. The third connecting member 21 and the cover plate 22 together constitute the second door assembly 20. The cover plate 22 is arranged on the side of the third connecting member 21 away from the first door assembly 10. The cover plate 22 can be arranged on the third connecting member 21 by bonding or snapping.

[0060] See also Figure 3 In some embodiments, the third connecting member 21 includes a first part 211 and a third part 213 arranged in sequence; the first part 211 is provided with a first end 2111 and a second end 2122 along the third direction, and the third part 213 is provided with a third end 2112 and a fourth end 2123 along the third direction, the first end 2111 and the third end 2112 are connected to the first connecting member 11, and the first end 2111 and the third end 2112 limit the movement of the third connecting member 21 along the first direction and / or the second direction; the second end 2122 and the fourth end 2123 are connected to the second connecting member 12, and the second end 2122 and the fourth end 2123 limit the movement of the third connecting member 21 along the third direction.

[0061] It can be understood that in some embodiments, the size of the third connecting member 21 is similar to that of the cover plate 22. In order to reduce the weight of the second door assembly 20 and reduce the structure of the second door assembly 20, the third connecting member 21 is split into a first part 211, a second part 212 and a third part 213. The first part 211 and the third part 213 are used to connect to the first door assembly 10, and the second part 212 is used to connect to the cover plate 22.

[0062] The first portion 211, the second portion 212 and the third portion 213 are sequentially arranged along the second direction (eg Figure 3 As shown in the figure, the first part 211 is arranged in sequence from left to right. Figure 3 The upper and lower ends (along the third direction) are defined as the first end 2111 and the second end 2122, and the third portion 213 is as shown in FIG. Figure 3 The upper and lower ends shown are defined as the third end 2112 and the fourth end 2123, the first end 2111 and the third end 2112 are arranged on the same side, the first end 2111 and the third end 2112 are used to connect with the first connecting member 11, and the connection method can be a connection achieved by snap-on or threaded fixed connection, etc. When the first connecting member 11 is connected to the first end 2111 and the second end 2122, the second door assembly 20 is detachably fixed to the first door assembly 10, so that the first door assembly 10 and the second door assembly 20 are preliminarily detachably connected.

[0063] See also Figure 3 and Figure 6 The second end 2122 and the fourth end 2123 are connected to the second connecting member 12. Specifically, an ear plate perpendicular to the third connecting member 21 is provided at the second end 2122 and the fourth section. The ear plate is arranged parallel to the second connecting member 12. Threaded holes are provided on the second connecting member 12 and the ear plate. The second connecting member 12 and the ear plate are connected together by threaded fasteners to limit the freedom of the second door assembly 20 in the second direction.

[0064] See also Figure 4 and Figure 5 In some embodiments, the first connecting member 11 includes a main body portion 123 and a clamping portion 122 , and the clamping portion 122 protrudes from the surface of the main body portion 123 .

[0065] The first connecting member 11 is used to connect the first door assembly 10 and the second door assembly 20. The first connecting member 11 can be divided into a main body portion 123 and a clamping portion 122 according to the different components it connects. Specifically, the main body portion 123 is used to connect to the door body 13, and the clamping portion 122 is used to connect to the third connecting member 21 to limit the freedom of the third connecting member 21 in the third direction. The clamping portion 122 is convex in shape, and the convex surface extends toward one side of the third connecting member 21.

[0066] like Figure 2As shown, in some embodiments, the first connecting member 11 is used to connect the first door assembly 10 and the second door assembly 20. At the same time, part of the structure of the first connecting member 11 is exposed to the outside, so its external structure needs to be considered. In some test examples, the first connecting member 11 is divided into two parts, a first bracket 112 and a second bracket 113. In this way, the first bracket 112 and the second bracket 113 can be set with different decorative colors respectively, so that the decorative effect of the oven door assembly 100 is better and more.

[0067] The above-mentioned clamping portion 122 can be provided in sections or as a whole, and can be adapted according to the clamping slot 2121 that cooperates with it.

[0068] Please continue reading Figure 5 In some embodiments, a notch is provided on one side of the first portion 211 and the third portion 213 close to the first connecting member 11, and the cover plate 22 is located on one side of the notch. The notch and the cover plate 22 form a first card slot in the first portion 211 and a second card slot in the third portion 213. The clamping portion 122 is provided in the first card slot and the second card slot to limit the second door assembly 20 from moving along the first direction.

[0069] As will be understood, a first engaging groove 2121 is provided on a side of the first portion 211 proximate to the first connector 11, and a second engaging groove 2124 is provided on a side of the third portion 213 proximate to the second connector 12. The first engaging groove 2121 and the second engaging groove 2124 are configured to engage with the aforementioned engaging portion 122. When engaged with the engaging portion 122, the first engaging groove 2121 and the second engaging groove 2124 restrict movement of the second door assembly 20 in the second direction. Optionally, the first engaging groove 2121 and the second engaging groove 2124 have the same depth. Specifically, the depths can be selected or adapted based on the size of the second door assembly 20 to ensure that the engaging portion 122 effectively retains the first engaging groove 2121 and the second engaging groove 2124 when engaged. This prevents the two engaging grooves from mismatching with the engaging portion 122, which could result in the two engaging grooves 2121 and the engaging portion 122 not adequately restricting the freedom of the second door assembly 20 and causing it to fall off during use.

[0070] It should be noted that the latching slot 2121 and the latching portion 122 can also limit the degree of freedom in the third direction to a certain extent, but completely limiting the degree of freedom in the third direction requires the cooperation of the matching member 23 and the second connecting member 12 .

[0071] See also Figure 6 and Figure 7 as well as Figure 8 In some embodiments, the first portion 211 and the third portion 213 of the third connecting member 21 are both provided with a mating member 23 extending along the first direction, and the mating member 23 cooperates with the second connecting member 12 to limit the movement of the second door assembly 20 along the first direction and / or the third direction.

[0072] It can be understood that the mating part 23 is used to connect with the second connecting part 12, mainly to limit the movement of the third connecting part 21 in the third direction. The mating part 23 can be an ear plate or a connecting plate. The mating part 23 is arranged on the third connecting part 21 and extends in a direction perpendicular to the third connecting part 21. Its length can extend to the second connecting part 12.
