Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a microwave oven door assembly and a microwave oven. Background Art

[0002] The door's fixing method is a critical step in the microwave oven manufacturing process, affecting not only the product's appearance and quality but also its sealing performance and safety. Currently, most microwave oven doors are fixed using a combination of screws and clips. While this method can achieve a certain degree of stable installation, it presents numerous problems and shortcomings.

[0003] The existing method of fixing the door of a microwave oven requires multiple steps, including snapping the door into place, manually pressing, and screwing. These steps not only increase the production time, but also increase the difficulty of operation, which is not conducive to improving production efficiency. Figure 1 、 Figure 2 As shown, the current mainstream method of fixing the door assembly of a microwave oven is to clip the door device 2 to the clip device 4 of the door panel device 1 through a clip, and then fix it by screwing. This fixing method requires the operator to manually press the door device 2 to the buckle position of the clip device 4, and then drive multiple (usually 4) screw devices 3 to ensure the stability of the door body. However, this fixing method has many processes, complicated operations, and poor controllability. Since the door body needs to be manually pressed during operation, once the pressing position deviates, it is easy to cause the door body to deform, thereby affecting the appearance quality and performance of the product.

[0004] Traditional screw and clip installation methods require a large number of screws and clips, which not only increases production costs but also wastes resources. Furthermore, the large number of screws and clips increases the difficulty of subsequent maintenance and replacement. Furthermore, prolonged, repetitive operations can lead to worker fatigue, further increasing the risk of operational errors.

[0005] Therefore, a new, simple and reliable door fixing solution is urgently needed to solve these problems. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0040] In microwave oven manufacturing, the current mainstream door fixing method relies on a combination of screws and snap-on installation. This process is not only cumbersome and complex to operate, but also increases production hours and difficulty, reducing production efficiency. At the same time, manually tightening the door can easily lead to position deviation, which in turn causes the door to deform, affecting the product's appearance and quality.

[0041] In view of the above-mentioned existing technical status, Figures 3 to 7 As shown, the present application discloses a microwave oven door assembly, comprising:

[0042] The door panel device 1 includes a door panel body 11;

[0043] The door device 2 includes a door body 21 and a door frame 22. The door frame 22 is arranged around the outside of the door body 21.

[0044] The door panel body 11 and the door frame 22 are slidably connected via the sliding limit buckle 13 and the connecting slot 221 .

[0045] The microwave oven door assembly disclosed in the present application realizes a simple and stable installation of the door body through the ingenious design between the door panel device 1 and the door body device 2. Specifically, the door panel device 1 includes a door panel body 11, and the door body device 2 is composed of a door body 21 and a door frame 22 arranged around the outside of the door body 21. The door body 21 can be set as an integrally formed structure, or it can be connected and fixed as a whole through a detachable connection structure. The sliding connection between the door panel body 11 and the door frame 22 is achieved through the mutual cooperation of the sliding limit buckle 13 and the connecting card slot 221. During the installation process, it is only necessary to push the door body device 2 along the set sliding path to the corresponding position of the door panel device 1, and the sliding limit buckle 13 will automatically align and engage with the connecting card slot 221, thereby completing the installation and fixation of the door body assembly 100. This design greatly simplifies the installation steps, avoiding the tediousness and complexity of the traditional installation method of screwing and snapping. It not only saves the use of screws, but also reduces production hours and labor costs, thereby improving production efficiency. At the same time, the sliding snap-fit ​​design enables the door body to be automatically aligned during the installation process, avoiding position deviation and door body deformation caused by manual tightening, and ensuring the product's appearance quality and performance.

[0046] The microwave oven door assembly described in the present application has a simple structure and is easy to operate, which reduces the skill requirements for operating personnel, reduces the risk of operating errors, greatly improves production efficiency, and enhances the appearance quality and performance of the product; at the same time, since the use of screws and clips is reduced, the difficulty of subsequent maintenance and replacement is also reduced.

[0047] As a preferred embodiment of the present application, the sliding limit buckle 13 is provided on the door panel body 11, and the connecting slot 221 is located in the position where the choke slot 222 is provided on the door frame 22. This design enables the door assembly 2 to be smoothly and accurately attached to the door panel assembly 1 during installation through the cooperation between the sliding limit buckle 13 and the connecting slot 221. The provision of the choke slot 222 not only provides additional positioning and support, but also effectively prevents the door from loosening or shifting during long-term use, thereby ensuring the sealing and safe use of the microwave oven.

[0048] This design makes the disassembly and maintenance of the door assembly 100 easier, reducing maintenance costs and time.

[0049] As a preferred example of the present application, multiple sliding limit buckles 13 are provided corresponding to the connecting slots 221, and the locking directions of the multiple sliding limit buckles 13 are arranged in the same direction. During the actual installation process, the pairing of multiple buckles and slots not only ensures the smoothness of the sliding process and effectively prevents the door from shaking or shifting during use, thereby ensuring the stability and security of the connection of the microwave oven door assembly 100, but also achieves effective support and distribution of the weight of the door device 2 through multi-point fixation, extending the service life of the door assembly 100.

[0050] As a preferred example of the present application, the door panel body 11 and the door frame 22 slide and limit along the vertical direction from top to bottom, or the door panel body 11 and the door frame 22 slide and limit along the horizontal direction or along the inclined downward direction. In the example of the present application, four sliding limit buckles 13 are provided, two of which are respectively located on the left side of the door panel body 11 near the upper end and near the lower end, and the other two are respectively located on the right side of the door panel body 11 near the upper end and near the lower end. The clamping direction of the four sliding limit buckles 13 is designed to face upward. With the above design, during installation, it is only necessary to align the connecting slots 221 on the door frame 22 with the sliding limit buckles 13 on the door panel body 11, and then gently push along the set sliding direction. The four sliding limit buckles 13 will smoothly snap into the corresponding connecting slots 221 to achieve a stable limited connection. This design not only simplifies the installation process, but also ensures the stability and consistency of the door body assembly 100.

[0051] The reasonable sliding limit design and clever buckle layout bring many advantages to the installation and use of the microwave oven door assembly 100, which not only improves the stability and safety of the product, but also reduces production costs and maintenance difficulty.

[0052] As a preferred example of the present application, the slip-limiting buckle 13 includes a first recessed portion 131, a first protruding portion 133 disposed within the first recessed portion 131, a first engaging plate 132 disposed on the first protruding portion 133, and a first engaging gap 135 formed between the first engaging plate 132 and the first protruding portion 133. This configuration discloses a structure of the slip-limiting buckle 13. By cleverly disposing the first protruding portion 133 within the first recessed portion 131, this design not only enhances the buckle's structural strength but also provides a reliable foundation for achieving precise positioning. Furthermore, the first engaging plate 132 is mounted above the first protruding portion 133, cleverly leaving a first engaging gap 135 between the first engaging plate 132 and the first protruding portion 133. When the door panel body 11 and the door frame 22 are slidably engaged with each other through the sliding limit buckle 13 and the connecting slot 221, this engaging gap plays a key role in engaging and limiting. By adjusting the setting position of the first engaging plate 132 so that it fits tightly with the first engaging gap 135, the components can be effectively locked within a predetermined sliding range, which not only prevents the components from being damaged due to excessive sliding, but also ensures the stability and reliability of the assembly of the entire door body assembly 100. As a specific example of this application, the first engaging plate 132 is a engaging plate with the first protrusion 133 bent upward, and a first reinforcing groove 134 is formed on the first protrusion 133 on one side of the first engaging plate 132. This arrangement not only enhances the firmness of the engaging, but also makes the buckle structure more compact and beautiful.

[0053] As a preferred example of the present application, the connecting slot 221 includes a limiting portion 2211 and a connecting portion 2212, wherein the connecting portion 2212 is connected to the limiting portion 2211, and the width of the connecting portion 2212 is greater than the width of the limiting portion 2211. In the example of the present application, the width of the connecting portion 2212 is as follows: Figure 6 As shown in the direction perpendicular to the clamping direction of the first clamping plate 132, when the door body device 2 is installed on the door panel device 1, the first clamping plate 132 is first slid and inserted into the connecting portion 2212 of the connecting slot 221 for positioning, and the door body device 2 is further slid and installed until the first clamping plate 132 slides to the limiting portion 2211 for clamping and limiting.

[0054] As a preferred example of the present application, a support boss 12 is provided on the door panel body 11. Two support bosses 12 are provided, one located near each end of the door panel body 11 in the longitudinal direction, and the two support bosses 12 are arranged parallel to the width direction of the door panel body 11. A plurality of slide limit buckles 13 are all provided on the support bosses 12. In the example of the present application, the longitudinal direction of the door panel body 11 is the left-right direction, and the width direction of the door panel body 11 is the up-down vertical direction.

[0055] This arrangement, through the introduction of support bosses 12, provides a solid support base for the sliding limit buckle 13, enhancing the buckle's load-bearing capacity and stability. The parallel arrangement of the two support bosses 12 effectively disperses the weight of the door assembly 2, preventing deformation or damage caused by single-point stress. Furthermore, centralizing the sliding limit buckle 13 on the support bosses 12 not only simplifies the structure of the door panel body 11 but also improves installation accuracy and efficiency, facilitating disassembly and repair of the door assembly 100 and reducing subsequent maintenance costs.

[0056] As a preferred example of the present application, the support boss 12 includes a support plate 121, a reinforcement boss 122 is provided on the support plate 121, and a first limiting flange 123 and a second limiting flange 124 are provided on the left and right sides of the reinforcement boss 122, respectively. The first limiting flange 123 and the second limiting flange 124 are provided along the vertical direction. This setting is achieved by optimizing the structure of the support boss 12. The support plate 121 serves as the basic structure and provides a stable support surface. By providing the reinforcement boss 122 on the support plate 121, the structural strength and bearing capacity of the entire support boss 12 are significantly enhanced by increasing the local thickness or height. The first limiting flange 123 and the second limiting flange 124 distributed on the left and right sides of the reinforcement boss 122 not only further reinforce the support boss 12, but also limit the horizontal movement of other components cooperating therewith, thereby ensuring the stability and accuracy of the entire structure. When external forces act on the supporting boss 12 , the reinforcing boss 122 cooperates with the limiting flange to effectively resist deformation and displacement, thereby ensuring the stability of the supporting boss 12 and its connecting structure.

[0057] The microwave oven door assembly 100 of the present application also includes other existing technical structures such as a sealing ring, a handle 14, a door lock mechanism, etc., which will not be described in detail in this application.

[0058] The present application also discloses a microwave oven, including a cabinet defining a cooking cavity therein, and a door assembly 100 for opening and closing the cooking cavity provided in front of the cabinet. The door assembly 100 adopts the structure of the above-mentioned embodiment.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
