Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a microwave oven door assembly and a microwave oven. Background Technology

[0002] The door structure is one of the most important components of a microwave oven. It not only facilitates the user's loading and unloading of food but also allows them to observe the cooking process through the glass window, directly impacting the user's operating experience. The door assembly includes the door frame, which is typically made of plastic and features clips for mechanically securing the glass panel. If the clips and door frame are molded as a single piece, the lack of elastic deformation capacity can cause significant difficulties when assembling the door panel, increasing assembly complexity and cost.

[0003] To address this, Chinese patent application CN201921168676.6 discloses a microwave oven door structure, including a door frame and a front glass panel. The front surface of the door frame has a receiving groove for placing the front glass panel. One side of the receiving groove has a through hole penetrating the bottom wall of the receiving groove from front to back. The structure also includes at least one fixing member for securing the front glass panel. The fixing member passes through the through hole, with a portion abutting against the front surface and / or side wall of the front glass panel, and the other portion fixed to the rear space of the receiving groove, thus securing the front glass panel within the receiving groove. This solution, through the combination of adhesive and the fixing member, facilitates the secure placement of the front glass panel within the door frame. However, because the adhesive is prone to aging and failure after long-term use, the glass panel may become loose or even fall off, severely impacting the user experience.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that the glass plate of existing microwave ovens tends to loosen after prolonged use due to the adhesive used, which affects the user experience.

[0006] To address the aforementioned problems, this utility model provides a microwave oven door assembly, including a door frame and a glass panel. The door frame has an opening, and the glass panel is used to seal the opening. The door frame has first latches on opposite sides of the opening to limit the glass panel in a first direction. The door frame also includes an elastic element, which extends into the opening to exert a force on the assembled glass panel to limit it in a second direction.

[0007] This application utilizes the elastic deformation of the elastic element to exert force on the assembled glass plate, thereby overcoming the problem of unstable glass plate fixation caused by adhesive aging and failure in traditional adhesive fixing methods. It also enhances the fixing stability of the glass plate through physical limiting, taking into account both the convenience and tightness of assembly, and reducing safety hazards. Through the cooperation of the first buckle and the elastic element, the glass plate is stably installed, which helps to improve the market competitiveness of the product and meet consumers' demand for high-quality and easy-to-use products.

[0008] Preferably, the door frame further includes a limiting member, and the limiting member and the elastic member are located at both ends of the opening and on the same side of the opening. This arrangement involves the upper edge of the glass plate abutting against the limiting member, while the other upper side of the glass plate abuts against the elastic member. The elastic member deforms and generates a restoring force on the glass plate, preventing the glass plate from wobbling freely, thus balancing the tightness of the assembly with ease.

[0009] Preferably, the limiting member is L-shaped and integrally formed with the door frame. This design not only improves the mechanical strength of the limiting member but also increases the contact area between the limiting member and the glass plate to distribute the force, resulting in a longer service life.

[0010] Preferably, the door frame further includes a reinforcing member located on the side of the elastic member away from the glass panel, with a gap between the reinforcing member and the glass panel. This arrangement allows the elastic member to be fixed in place by one end abutting against the edge of the glass panel and its sidewall abutting against the reinforcing member under stress; at the same time, the reinforcing member will not interfere with the assembly of the glass panel.

[0011] Preferably, the elastic member includes a connecting portion and an elastic arm connected together, the elastic arm being inclined along the diagonal direction of the opening, and the reinforcing member being disposed near the free end of the elastic arm.

[0012] This design allows the elastic arm to generate a more uniform and stable reaction force when subjected to pressure during glass plate assembly, thereby more effectively limiting the glass plate in the second direction and improving the stability of the glass plate. At the same time, it makes it easier for the glass plate to slide into the opening of the door frame during assembly. The elastic arm can automatically rebound after the glass plate is inserted, providing a stable limiting effect on the glass plate, simplifying the assembly process and improving assembly efficiency.

[0013] Preferably, the reinforcing member has a chamfer on the side near the elastic member, and the elastic member and the reinforcing member are in surface contact. This arrangement can further increase the contact area between the reinforcing member and the elastic member, thereby enabling the reinforcing member to stably apply force to the elastic member and effectively preventing the elastic member from breaking due to excessive force concentration.

[0014] Preferably, the door frame further includes a second latch and a third positioning member, which are located at the left and right ends of the opening. This arrangement allows the glass panel to slide towards the second latch after being engaged with the first latch, so that one side of it is inserted into the second latch and the other side abuts against the third positioning member, thereby limiting the glass panel in the left and right directions.

[0015] Preferably, the door frame further includes a boss located on the outer periphery of the opening. This arrangement allows the boss to cooperate with the first and second latches to limit the glass panel in the front-rear direction, while also reinforcing the opening and facilitating the assembly of the glass panel.

[0016] Preferably, the microwave oven door assembly further includes a door frame, a cover, and a door sticker connected in sequence, with the glass plate located on the side of the door frame away from the cover.

[0017] This utility model also provides a microwave oven, including the microwave oven door assembly described above.

[0018] Compared with the prior art, the microwave oven door assembly and microwave oven described in this utility model embodiment have the following beneficial effects: 1) The glass plate is limited by the cooperation of the rigid first buckle and the elastic element, which can take into account both the ease of assembly and the connection strength, and effectively prevent the glass plate from loosening and falling off, which is especially suitable for household microwave ovens that need to be frequently opened and closed; 2) By setting a reinforcing member on one side of the elastic element, it will not interfere with the elastic element in the initial deformation process, and at the same time, it can limit the elastic element to apply a stable force to limit the glass plate; 3) It requires little modification to the existing structure and is easy to implement.

[0025] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Without conflict, the technical features of the embodiments of this invention can be combined with each other.

[0026] It should be noted that all directional and positional terms used in this utility model, such as "up," "down," "left," "right," "front," and "back," are only used to explain the relative positional relationships and connection situations between components in a specific state. They are merely for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0028] In the description of this specification, references to the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the present invention.

[0029] The current assembly of the front glass panel of a microwave oven door assembly has the following shortcomings: If the glass panel is installed from the back of the door frame, positioned by the limiting frame, and then reinforced on the back, this mechanical fixing method is cumbersome. If adhesive is used, the adhesive is prone to aging and failure after long-term use, leading to unstable glass panel fixation and even safety hazards. Furthermore, the door frame 1 is usually made of plastic and has a limiting structure for fixing the glass panel 2. If it is integrally molded with the door frame, the lack of elastic deformation capacity will make door panel assembly difficult. If the elastic buckle arm is located on the extension wall of the door frame 1, there is a risk of unstable fixation during long-term use. Therefore, the applicant proposes the following technical solution:

[0030] like Figure 1-4As shown, a microwave oven door assembly includes a door frame 1 and a glass panel 2. The door frame 1 has an opening 11, and the glass panel 2 is used to seal the opening 11. The door frame 1 has first latches 12 on opposite sides of the opening 11 for limiting the glass panel 2 in a first direction. The door frame 1 also includes an elastic member 13, which partially extends into the opening 11 to exert a force on the assembled glass panel 2 to limit it in a second direction.

[0031] This solution utilizes the elastic deformation of the elastic element 13 to exert force on the assembled glass plate 2, thereby overcoming the problem of unstable fixation of the glass plate 2 due to adhesive aging and failure in traditional adhesive fixing methods. It also enhances the fixing stability of the glass plate 2 through physical limiting, balancing ease of assembly and tightness, and reducing safety hazards. The cooperation between the first buckle 12 and the elastic element 13 achieves a stable installation of the glass plate 2, helping to improve the product's market competitiveness and meet consumer demand for high-quality, easy-to-use products. As an example of this utility model, the first direction is the front-to-back direction, and the second direction is the up-and-down direction.

[0032] Specifically, when the glass panel 2 is not installed, the elastic element 13 is in its natural state, at which time it partially extends into or faces the interior of the opening 11; when the glass panel 2 is installed, the elastic element 13 is in a stressed state, with one end abutting against the edge of the glass panel 2, thereby fixing it so that the glass panel 2 cannot move after being installed in the door frame 1, thus playing a stabilizing role.

[0033] As an example of this utility model, the door frame 1 further includes a limiting member 15. The limiting member 15 and the elastic member 13 are located at both ends of the opening 11 and on the same side of the opening 11. The limiting member 15 abuts against the glass plate 2. During assembly, the glass plate 2 is snapped into the first buckle 12 from the upper part of the opening 11, and then pushed into the first buckle 12 at the lower part of the opening 11. The upper edge of the glass plate 2 abuts against the limiting member 15, while the other side of the upper end of the glass plate 2 abuts against the elastic member 13. The elastic member 13 will deform and generate a restoring force on the glass plate 2, so that the glass plate 2 cannot shake freely.

[0034] Preferably, the limiting member 15 is L-shaped and integrally formed with the door frame 1. This design not only improves the mechanical strength of the limiting member 15, but also increases the contact area between the limiting member 15 and the glass plate 2 to distribute the force, resulting in a longer service life.

[0035] As an example of this utility model, the door frame 1 further includes a reinforcing member 14, which is located on the side of the elastic member 13 away from the glass plate 2, and a gap exists between the reinforcing member 14 and the glass plate 2. This arrangement allows the elastic member 13 to be fixed in place by one end abutting against the edge of the glass plate 2 and its sidewall abutting against the reinforcing member 14 at the same time, without interfering with the assembly of the glass plate 2.

[0036] Preferably, the elastic member 13 includes a connecting portion and an elastic arm connected together, the elastic arm being inclined along the diagonal direction of the opening 11, and the reinforcing member 14 being disposed near the free end of the elastic arm.

[0037] This design allows the elastic arm to generate a more uniform and stable reaction force when subjected to pressure during the assembly of the glass plate 2, thereby more effectively limiting the glass plate 2 in the second direction and improving the fixing stability of the glass plate 2. At the same time, it makes it easier for the glass plate 2 to slide into the opening 11 of the door frame 1 during assembly. The elastic arm can automatically rebound after the glass plate 2 is inserted, providing a stable limiting effect on the glass plate 2, simplifying the assembly process and improving assembly efficiency. The position of the reinforcing member 14 can prevent the elastic arm from breaking or deforming due to fatigue during long-term use, ensuring the long-term stability and reliability of the elastic member 13.

[0038] Preferably, the reinforcing member 14 has a chamfer on the side near the elastic member 13, and the elastic member 13 and the reinforcing member 14 are in surface contact. This arrangement can further increase the contact area between the reinforcing member 14 and the elastic member 13, thereby enabling the reinforcing member 14 to stably apply force to the elastic member 13 and effectively preventing the elastic member 13 from breaking due to excessive force concentration.

[0039] As an example of this utility model, the door frame 1 further includes a second buckle 16 and a third positioning member 17, which are located at the left and right ends of the opening 11, that is, at both ends in the length direction. When the glass plate 2 is engaged with the first buckle 12, it slides towards the second buckle 16, so that one side of it is inserted into the second buckle 16 and the other side abuts against the third positioning member 17, thereby limiting the glass plate 2 in the left and right direction.

[0040] Preferably, the door frame 1 further includes a boss 18, which is located on the outer periphery of the opening 11. This arrangement allows the boss 18 to cooperate with the first latch 12 and the second latch 16 to limit the glass plate 2 in the front-back direction, while also reinforcing the opening 11 and facilitating the assembly of the glass plate 2.

[0041] The microwave oven door assembly also includes a door frame 3, a cover 5, and a door sticker 6 connected in sequence, with the glass plate 2 located on the side of the door frame 3 away from the cover 5. The microwave oven door assembly also includes a door hook 4, and the specific assembly structure of the door frame 3, cover 5, and door sticker 6 is existing technology.

[0042] This utility model also provides a microwave oven, including the aforementioned microwave oven door assembly. The microwave oven has the same beneficial effects as the door assembly, and will not be described further here.

[0043] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
