[0002] Chinese invention patent 2014800046747 discloses a door for a microwave appliance, comprising an outer glass panel distributed over the entire outer perimeter of the door, and an inner glass panel distributed at least over the central portion of the inner perimeter of the door. The door includes a door frame covering at least the circumferential side of the oven door, and a wave-damping system. The outer glass panel, the inner glass panel, and the door frame form the shell of the door.

[0003] In this patent, the wave-damping system is actually a metal panel fixed to the outside of the inner glass panel. The door frame is made of plastic and is connected to the wave-damping system with adhesive. When the microwave oven is operating, the heat generated is transferred to the door. Because the door frame is made of plastic, it easily absorbs heat and heats up, potentially melting and affecting the overall quality. Furthermore, current microwave ovens are becoming more multifunctional, integrating oven or air-fryer functions. When the microwave oven is used in oven mode, the heat generated is even greater, further increasing the risk of the door frame overheating. Summary of the Invention

[0042] The present invention will be further described below with reference to specific embodiments:

[0043] A microwave oven door includes an outer door glass 11, an inner cover 12, an inner door glass 13, and a central glass 14. The microwave oven heat-resistant body 1 in this patent is used in a microwave oven, which can be a regular microwave oven, a microwave oven with a built-in oven and grill function, or a microwave oven with a built-in oven, steam oven, and grill function. (Reference) Figure 1 The microwave oven includes a frame 2, within which are an inner liner and an outer liner. One side of the inner liner is open. A door 1 is rotatably mounted on the front side of the inner liner to close it. Correspondingly, the door 1 is provided with a hinge structure for rotatably connecting the door 1 to the inner liner. Figure 9 As shown, some pull-out guide rails can also be provided on the door body 1 so that the door body 1 can be closed on the inner liner by pulling it out.

[0044] 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.

[0045] like Figure 3As shown, the inner cover 12 in this patent consists of two parts, including an outer frame 124 and a shielding baffle 125 connected in the outer frame 124. The outer frame 124 is square with a square opening structure in the center. The outer edge of the outer frame 124 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 frame 124 is provided with an annular wave-blocking groove 1221. The wave-blocking groove 1221 and the peripheral wall 126 can be directly formed by stamping during the manufacturing of the outer 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 cover. The outer edge of the shielding baffle 125 is provided with a groove 1222. The groove 1222 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 cover by glue or welding, and the groove 1222 is located on the slot of the wave-blocking groove 1221. The shielding mesh 121 is opened on the shielding baffle 125, and the wave-blocking groove 1221 and the groove 1222 cooperate to form the wave-blocking part 122.

[0046] 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.

[0047] 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 for placing and positioning the central glass 14. Figure 6 , 7As 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.

[0048] Specifically, such as Figure 4 , 8As 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 mounting 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.

[0049] 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.

[0050] Furthermore, the top of the glass bracket 16 is provided with a spring pin 162, and the inner cover 12 has a cover positioning hole 123 corresponding to the spring. Figure 7As shown, the glass support 16 has an internal hollowed-out design, with a cavity formed near the top of the glass support 16. The spring pin 162 is located within this cavity, extending upwards through the cavity and exposed outwards. The cover positioning hole 123 is directly formed on the peripheral wall 126 of the inner cover 12. When the inner cover 12 is placed over the outer door glass 11, its fixed installation is achieved by inserting the spring pin 162 into the cover positioning hole 123.

[0051] The inner cover 12 involved in this patent is made of metal, ensuring that it is a single, integral structure. During microwave oven operation, the metal inner cover 12 has better temperature resistance and more even heat distribution, effectively avoiding the risk of the material on the door 1 melting due to overheating. Furthermore, this patent further enhances the heat insulation effect by installing an inner door glass 13 on the inner cover 12, ensuring that the temperature of the door 1 remains within a safe range and further reducing the risk of burns.

[0052] Furthermore, this patent enables rapid installation of the inner cover 12 by introducing a spring pin 162 structure, significantly reducing installation difficulty. The spring pin 162 is simple in design, low in cost, and easy to mass-produce.

[0053] Furthermore, a cover connecting seat 111 is also fixed on the outer door glass 11. The connecting seat has a cover connecting hole 112. When the inner cover 12 is fixed to the inner side of the outer door glass 11, the cover connecting hole 112 is opposite to the peripheral wall 126 of the inner cover 12, and is used to connect the two by setting fasteners. Figure 6 As shown, the cover connecting seat 111 is specifically an "L"-shaped angle iron structure. One side is directly fixed to the outer door glass 11 with glue, and the other side faces downward, with the cover connecting hole 112 for aligning with the peripheral wall 126 of the inner cover 12. When the inner cover 12 is placed on the outer door glass 11, the connection between the two is achieved by fasteners on the peripheral wall 126 of the inner cover 12 and the cover connecting hole 112. Screws are generally used as fasteners.

[0054] Furthermore, it also includes a glass fixing block 17, on which a plurality of second glass placement grooves 171 are formed; the length of the glass fixing block 17 is adapted to the depth of the inner cover 12, and the glass fixing block 17 is installed on the inner door glass 13 through the second glass placement grooves 171 and is located within the inner cover 12 and is limited therein. Figure 3As shown, in this embodiment, several glass fixing blocks 17 are provided, which are sequentially and spaced apart on the upper end of the inner door glass 13. Since there are two inner door glass 13s in this embodiment, the glass fixing blocks 17 are integrally formed with two second glass placement grooves 171. The upper end of the inner door glass 13 is locked in the second glass placement grooves 171 to achieve the installation of the glass fixing blocks 17. The length of the glass fixing blocks 17 is adapted to the depth of the inner cover 12. When the inner cover 12 covers the glass fixing blocks 17, the inner wall of the inner cover 12 abuts against the glass fixing blocks 17 to limit and front-back positioning of the glass fixing blocks 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.

[0055] 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 silicone material, 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.

[0056] Furthermore, the outer end of the peripheral wall 126 of the inner cover 12 is provided with a sealing element 15 for abutting against the outer door glass 11. For example... Figure 3 , 5 As shown, the sealing element 15 is specifically a silicone element covering the outer end of the peripheral wall 126, which prevents external moisture or dirt from entering the door body 1.
