[0046] A quick-installation door includes an outer door glass 11, an inner cover 12, an inner door glass 13, and a central glass 14. The quick-installation door 1 in this patent is generally used in household appliances, such as microwave ovens and ovens. In this embodiment, the quick-installation door is used in a microwave oven that integrates microwave and oven functions. (See reference...) Figure 1 , 2 11. The microwave oven includes a frame 2, in which an inner liner and an outer liner are provided. One side of the inner liner is open, and the door 1 is rotatably disposed on the front side of the inner liner to close it; in some other embodiments, such as Figure 11 As shown, the door 1 can be opened or closed by pulling it out by setting a pull-out guide rail on the door body 1.

[0047] The outer door glass 11 is located on the front side of the door body 1, and is generally provided with a handle for user operation. The inner cover 12 is fixed inside the outer door glass 11. The inner cover 12 is provided with a shielding mesh portion 121 and a wave-damping portion 122 located on the outer edge of the shielding mesh portion 121. The inner door glass 13 is fixed on the shielding mesh portion 121 of the inner cover 12, and the central glass 14 is fixed in the inner cover 12.

[0048] like Figure 3 As shown, the inner cover 12 in this patent includes an outer cover frame 124, a shielding baffle 125 connected in the outer cover frame 124, and an outer cover wall 127 connected outside the outer cover frame 124 and the shielding baffle 125. The outer cover frame 124 is square with a square opening structure formed in the center. The outer edge of the outer cover wall 127 is provided with a raised and annular peripheral wall 126, which allows it to cover the rear side of the outer door glass 11. The inner edge of the outer cover frame 124 is provided with an annular wave-blocking groove 1221, which can be directly formed by stamping during the manufacturing of the outer cover frame 124. The shielding baffle 125 is square, and its size is slightly larger than the opening structure at the center of the outer frame 124 of the enclosure. The outer edge of the shielding baffle 125 is provided with a groove 1222, which is specifically a plurality of square groove structures sequentially opened on the outer edge of the shielding baffle 125. The shielding baffle 125 can be fixed to the opening structure at the center of the outer frame 124 of the enclosure by glue or welding, and the groove 1222 is located at the slot of the wave-blocking groove 1221. The shielding baffle 125 is provided with a shielding mesh 121, and the wave-blocking groove 1221 and the groove 1222 cooperate to form the wave-blocking part 122. The outer wall 127 of the enclosure also has a square opening structure at the center. The shielding baffle 125 and the outer frame 124 are connected to the outer wall 127 of the enclosure. The outer wall 127 of the enclosure is provided with a fastening assembly 18 for detachably fixing to the inner side of the outer door glass 11.

[0049] The inner door glass 13 is fixed to the shielding mesh portion 121 of the inner cover body 12. Specifically, the inner door glass 13 is glued to the groove portion 1222 of the shielding mesh portion 121, and the outer edge of the inner door glass 13 simultaneously covers the wave-damping groove 1221, so that the inner door glass 13 and the inner cover body 12 are connected to form a complete surface.

[0050] The central glass 14 is fixed in the inner cover 12. In this embodiment, a glass bracket 16 located in the inner cover 12 is fixed on the outer door glass 11. The glass bracket 16 is provided with a plurality of first glass placement grooves 161, which are used to limit the movement of the central glass 14 in its facing direction through the first glass placement grooves 161. Figure 3 , 4 As shown, in this embodiment, two glass supports 16 are provided, which are respectively fixed on the left and right sides of the outer door glass 11. The glass supports 16 are strip-shaped and can be directly fixed to the inner side of the outer door glass 11 by adhesive, and are respectively arranged on the left and right sides. The upper end of the glass support 16 is provided with an upper stop 164, and the lower end of the glass support 16 is provided with a support platform 167. The support platform 167 is provided with a plurality of baffles 163, and a first glass placement groove 161 is formed between the baffles 163. The baffles 163 include first limiting segments 163 arranged vertically. 1. Offset section 1632 and second limiting section 1633, the first limiting section 1631 is used to cooperate with the second limiting section 1633 on the adjacent baffle 163 to limit the central glass 14 located in the first glass placement groove 161. An inclined guide groove 1634 is formed between the offset sections 1632 of the adjacent baffle 163. The inclined guide groove 1634 is used to allow the central glass 14 to enter the first glass placement groove 161 at an angle along the inclined guide groove 1634, and to allow the upper end of the central glass 14 to enter the upper baffle 164 from the front side of the glass bracket 16.

[0051] Specifically, such as Figure 4 , 6As shown, in this embodiment, two central glass panes 14 are provided. The upper end of one central glass pane 14 is located below the upper baffle 164, while the upper end of the other central glass pane 14 is located in front of the upper baffle 164. Therefore, in this embodiment, two baffles 163 are provided, and a first glass placement groove 161 for installing the central glass pane 14 is formed between the two baffles 163. Specifically, the support platform 167 is formed by providing a hollowed-out portion 172 on the glass bracket 16. The support platform 167 is horizontal, and two baffles 163 are integrally formed on the support platform 167, as well as a small baffle 1635 located in front of the two baffles 163. The upper baffle 164 is also integrally formed above the glass bracket 16 and is vertically opposite to the support platform 167. Since the two guard edges 163 are opposite each other, and the guard edge 163 on the rear side is slightly higher than the guard edge 163 on the front side, a slanted guide groove 1634 can be formed on the offset portion on the two guard edges 163, and a vertical placement space is formed between the first limiting segment 1631 of the first guard edge 163 and the second limiting segment 1633 of the second guard edge 163. During installation, the central glass 14 can be tilted first, so that its lower end is inserted into the inclined guide groove 1634. Then, the central glass 14 is rotated so that it continues to enter along the baffle 163, and the upper end of the central glass 14 is flipped into the lower baffle 164 of the glass bracket 16. At the same time, the lower end of the central glass 14 is located at the bottom of the first glass placement groove 161. At this time, the first limiting segment 1631 of the first baffle 163 and the second limiting segment 1633 of the second baffle 163 are used to limit the front and rear of the central glass 14, and the upper baffle 163 is used to limit the upper limit, thus realizing the installation of the central glass 14.

[0052] The other central glass 14, with its upper end positioned in front of the upper stop 164, can be directly inserted from above into the space between the stop 163 and the small stop 1635 for positioning. The manufacturer can also increase the number of installable central glass 14s by increasing the number of stops 163. The central glass 14 is used for further thermal insulation of the door 1, and in this patent, the central glass 14 is further limited and fixed by the upper stop 164, and its rapid installation is achieved through the structure of the inclined guide groove 1634.

[0053] Furthermore, it also includes a glass fixing block 17, on which a plurality of second glass placement grooves 171 are formed; such as Figure 3 , 4As shown, the length of the glass fixing block 17 is adapted to the depth of the inner cover 12. The glass fixing block 17 is installed on the inner door glass 13 through the second glass placement groove 171 and is positioned within the inner cover 12. In this embodiment, the glass fixing block 17 is elongated. Since there are two inner door glass 13s in this embodiment, the glass fixing block 17 is integrally formed with two second glass placement grooves 171. The installation of the glass fixing block 17 is achieved by having the upper end of the inner door glass 13 inserted into the second glass placement groove 171. The length of the glass fixing block 17 is adapted to the depth of the inner cover 12. When the inner cover 12 covers the glass fixing block 17, the inner wall of the inner cover 12 abuts against the glass fixing block 17 to limit and front-back positioning of the glass fixing block 17. This achieves the positioning of the upper end of the inner door glass 13, thereby increasing the stability of the inner door glass 13 after installation.

[0054] Furthermore, the glass fixing block 17 is provided with multiple hollow portions 172. For example... Figure 4 As shown, the fixing block 17 on the glass is typically made of metal, and during its manufacturing process, these cutouts 172 are directly formed on it. These cutouts 172 can be designed to be square or round, with the aim of increasing the contact area between the fixing block 17 on the glass and the air, thereby improving its heat dissipation performance, preventing the inner cover 12 from overheating, and further enhancing the anti-scalding and heat-resistant properties of the door body 1 of this patent application.

[0055] Furthermore, the two ends of the fixing block 17 on the glass are provided with overlapping arms 173, and the upper end of the glass support 16 is provided with an overlapping groove 166 for placing the overlapping arms 173. Figure 3-6 As shown, the overlapping groove 166 is integrally formed on the top of the glass support 16. The overlapping arm 173 on the glass fixing block 17 can be directly placed in the overlapping groove 166, and the overlapping arm 173 is limited by the overlapping groove 166, thereby further limiting the glass fixing block 17. In addition, the glass fixing block 17 is provided with a snap-fit ​​spring 174 that abuts against the edge of the glass support 16, such as... Figure 7 As shown, the snap-fit ​​spring is integrally formed on the front side of the overlapping arm 173. The snap-fit ​​spring is L-shaped and abuts against the edge of the upper stop 164 of the glass bracket 16 from bottom to top, thereby limiting the upper and lower positions of the upper fixing block 17 on the glass. Thus, the upper fixing block 17 on the glass achieves its front-to-back and vertical positioning and is fixedly connected by the overlapping arm 173 and the snap-fit ​​spring 174.

[0056] Furthermore, corresponding fastening components 18 are provided on the outer side of the glass bracket 16 and the inner cover 12, allowing the inner cover 12 to be detachably fixed to the inner side of the outer door glass 11 via the fastening components 18. Figure 3-6 As shown, the fastening assembly 18 includes a fastening groove 185 formed between the glass fixing block 17 and the outer door glass 11, and a second fastening hook 186 disposed on the peripheral wall 126 of the inner cover 12. In fact, the glass fixing block 17 has a recess on the side near the outer door glass 11. After the glass fixing block 17 is fixed to the outer door glass 11 through the recess, a fastening groove is formed between the glass fixing block 17 and the outer door glass 11. The second fastening hook 186 is integrally formed on the upper peripheral wall 126 of the inner cover 12. During installation, the second fastening hook 186 can be directly fastened into the fastening groove 185.

[0057] In addition, such as Figure 7-10 As shown, the inner cover 12 has snap-fit ​​pins 181 on both sides of the peripheral wall 126, and a snap-fit ​​protrusion 182 in the middle of the snap-fit ​​pin 181. The glass bracket 16 has a snap-fit ​​slot 183 on its side wall, and a snap-fit ​​notch 184 corresponding to the snap-fit ​​protrusion 182 on the snap-fit ​​slot 183. During installation, the inner cover 12 is directly placed on the inner side of the outer door glass 11, and the glass bracket 16, the central glass 14, and the glass fixing block 17 are placed inside it. Then, the snap-fit ​​pins 181 are inserted into the snap-fit ​​slot 183, and the snap-fit ​​protrusion 182 is located in the snap-fit ​​notch 184 to achieve connection and fixation. At this time, the central glass 14 is positioned by the upper limit and the front and rear limit of the glass fixing block 17 of the inner cover 12. The fastening assembly 18 further includes a fastening block 187 disposed on the outer wall of the glass support 16 and a first fastening hook 188 disposed on the inner wall of the inner cover 12. Figure 7 , 8 As shown, the first snap hook 188 and the snap block 187 are respectively disposed on the snap protrusion 182 and the snap slot 183, which can be snapped and fixed when the inner cover 12 covers the outer door glass 11.

[0058] In this patent application, the door assembly and disassembly process is simple and quick. Only appropriate force is applied to engage the second latching hook 186 in the latching groove 185 and engage the first latching hook 188 on the latching block 187, while simultaneously positioning the latching pin 181 in the latching slot 183 to achieve connection. The aforementioned latching assembly 18 enables rapid door assembly, reducing assembly difficulty and increasing the accuracy of the assembled product.

[0059] In some embodiments, the fixing block 17 on the glass may not be provided, and the upper end of the central glass 14 can be directly limited by the inner cover 12. In contrast, providing the fixing block 17 on the glass can increase the stability of the central glass 14 after installation.
