Description

Technical Field

[0001] This utility model relates to the field of microwave oven technology, specifically to a door assembly for a microwave oven that reduces microwave leakage. Background Technology

[0002] A microwave oven is a kitchen appliance that uses microwaves to heat food. It features rapid heating, high efficiency, and ease of operation, and is widely used in both home and commercial settings. Microwave ovens generate microwaves through a magnetron, causing water molecules in the food to vibrate and generate heat through friction, thus achieving rapid heating.

[0003] However, in the short period between when the door is opened and when the microwaves stop working, existing microwave ovens may leak microwaves due to insufficient sealing between the door and the cavity, posing a safety hazard. Furthermore, traditional door assemblies usually require adjusting the gaps between the components and installing additional parts such as springs during assembly, making the assembly process cumbersome and increasing production costs and maintenance difficulties.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1:

[0024] As per the instruction manual Figure 1-4 As shown, a door assembly for a microwave oven with reduced microwave leakage includes, from the outside to the inside, a door handle 1, an outer door panel 2, an inner door panel 3, and a leak-proof component 4.

[0025] In this utility model, the door handle 1 is fixedly connected to one edge of the outer door panel 2. Insulating pads 13 are provided at the contact points between the two ends of the door handle 1 and the outer door panel 2. The inner side of the outer door panel 2 is fixedly connected to the door handle 1 through insulating plugs 14 and fastening screws 15. The insulating plugs 14 are in contact with the inner side of the outer door panel 2. The installation of the door handle 1 is simple and convenient, replacing the previous three-section complex door handle 1 structure.

[0026] In this utility model, the inner panel 3 is fitted inside the outer panel 2, and both the outer panel 2 and the inner panel 3 are groove structures of matching size. The upper and lower edges of the outer panel 2 are fixedly connected to the inner panel 3 by connecting screws, and the outer panel 2 is provided with corresponding countersunk screw holes 16 at the connecting screws to ensure flat assembly.

[0027] In this utility model, mounting plates 6 are connected to both sides of the inner panel 3 via inner brackets 5. The inner brackets 5 have a U-shaped structure, with one side fixed to the inner panel 3 and the other side abutting against the outer panel 2. The inner brackets 5 determine the installation positions of the integrated door hinge 7, the inner panel 3, and the outer panel 2, simplifying the installation process. The middle of the inner brackets 5 is fixed to the mounting plate 6 with fixing screws 17. The integrated door hinge 7 is fixed to the inner side of the mounting plate 6. The integrated door hinge 7 can effectively improve the door opening and closing force of the equipment, making the door opening smoother and reducing the metallic collision sound when the door is closed. The integrated door hinge 7 is a direct adoption of the existing mechanism, so the integrated door hinge 7 will not be described in detail.

[0028] In this utility model, the anti-leakage component 4 is located in the middle of the inner panel 3. The anti-leakage component 4 is composed of an anti-leakage groove plate 8 and a patch plate 9 that fit together. The patch plate 9 is fitted into one side of the anti-leakage groove plate 8. The inner side of the patch plate 9 is provided with multiple positioning posts 18. The patch plate 9 is fixed by welding after being inserted and positioned with the anti-leakage groove plate 8 through the positioning posts 18. The outer edge of the anti-leakage groove plate 8 is provided with choke teeth 10.

[0029] In this utility model, the back of the patch plate 9 is fixed to the inner door panel 3 via a first high-temperature resin plate 11 and a second high-temperature resin plate 12, and the inner door panel 3 is located between the first high-temperature resin plate 11 and the second high-temperature resin plate 12. Multiple bolts 19 are embedded and fixed inside the patch plate 9, and the bolts 19 pass through the first high-temperature resin plate 11, the inner door panel 3 and the second high-temperature resin plate 12 and are fixed with nuts 20. The size of the first high-temperature resin plate 11 matches that of the patch plate 9, and the shape of the second high-temperature resin plate 12 matches that of the inner door panel 3. The area of ​​the second high-temperature resin plate 12 is larger than that of the first high-temperature resin plate 11. Through the double-layer high-temperature resin plate structure, significant deformation of the door assembly during high-temperature use can be prevented.

[0030] In specific implementation of this utility model, when the microwave oven is working, the choke teeth 10 in the anti-leakage component 4 can effectively suppress microwave leakage, and the double-layer high-temperature resin plate prevents the door component from deforming significantly during high-temperature use. When the door is closed, the outer door panel 2 fits tightly with the oven cavity, enhancing the overall sealing performance. When the door is opened, the choke teeth 10 can still maintain microwave shielding for a short time until the microwave stops completely, thereby reducing the risk of leakage.

[0031] During the assembly process, the door components are easily fitted and spliced ​​by the matching outer door panel 2 and inner door panel 3. At the same time, the inner bracket 5 determines the installation depth for easy positioning. Meanwhile, the anti-leakage component 4 is spliced ​​by the corresponding anti-leakage groove plate 8 and patch plate 9, and is positioned and inserted by the positioning column 18 for easy welding and fixing.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
