Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking setting, especially relates to a microwave oven with buffer device. BACKGROUND

[0002] In the field of modern kitchen appliances, microwave ovens, as a convenient and efficient cooking tool, are widely used in households and catering places. With the improvement of consumers' requirements for use experience and quality, the design of the door assembly of microwave ovens has gradually become the focus of manufacturers' optimization, especially the pull-down door type microwave oven is favored due to its simple operation and high space utilization.

[0003] The door closing mechanism of traditional pull-down door type microwave ovens mainly relies on simple mechanical hinge structure, which is low in cost but lacks effective buffer mechanism. When the user closes the door with great force, the door will quickly hit the front plate of the microwave oven cavity, producing a loud noise. This noise not only affects the tranquility of the kitchen environment, but also may make the user feel uncomfortable, thereby reducing the overall use experience. In addition, frequent impact may cause the cavity front plate to deform, sag or coating to peel off, affecting the appearance and durability of the product. The integrity of the cavity front plate is directly related to the appearance and protection performance of the microwave oven, and the damaged front plate may make the internal electrical components and heating devices more vulnerable to external environment. The coating on the surface of the door may be worn due to impact, which may reduce its protective effect, thereby affecting the sealing performance of the microwave oven, leading to heat leakage, affecting the cooking efficiency, and even endangering food safety.

[0004] To solve the problem of impact when closing the door, there have been various attempts in the industry. Some manufacturers reduce the impact force by increasing the gap between the door and the cavity front plate, but this often sacrifices the sealing performance of the microwave oven, leading to heat leakage. Some other designs install rubber pads or elastic materials on the door to absorb impact energy, which can reduce the impact sound to some extent, but these materials are prone to aging and deformation after long-term use, losing the buffering effect and possibly affecting the performance due to dirt.

[0005] Some manufacturers try to achieve slow closing of the door through complex mechanical structures, but these solutions usually increase manufacturing costs and are difficult to maintain, which is not conducive to the popularization of products. Therefore, how to effectively solve the problem of impact when closing the door without increasing excessive cost and sacrificing other performance of the microwave oven has become a technical problem that needs to be solved in the industry.

[0006] In summary, the existing pull-down door type microwave oven has many deficiencies in the door closing mechanism, which affects the user experience, may lead to a decline in product quality, and even poses a potential threat to food safety. Therefore, in-depth research and improvement of this technical problem, optimization of the door closing mechanism, and improvement of the overall performance of the microwave oven and user satisfaction have become the common goal of the industry.

[0038] As shown in Figures 1-7 The application discloses a microwave oven with a buffering device, which comprises:

[0039] A hinge device 500 comprises a hinge connecting rod 5 hingedly connected to a door assembly 100, and a door hinge spring 7 arranged on the hinge connecting rod 5, wherein the door hinge spring 7 is in tension when the door assembly 100 is rotated to open relative to a cavity assembly 300, and the door hinge spring 7 can tightly adhere to a cavity front plate 9 of the cavity assembly 300 when the door assembly 100 loses external force.

[0040] A damping buffering device 400 comprises a damper 3, wherein a damping buffering head 303 of the damper 3 extends out of the cavity front plate 9, and the damping buffering head 303 can delay the closing speed of the door assembly 100 when the door assembly 100 is closed.

[0041] The microwave oven with a buffering device disclosed in the application mainly relies on the coordination of the hinge device 500 and the damping buffering device 400. When the user opens the oven door assembly, the hinge connecting rod 5 is hinged with the oven door assembly 100, the door hinge spring 7 bears the tension in the opening process and stores the elastic potential energy, so that the door hinge spring 7 can quickly release the stored energy when the external force of the oven door assembly 100 disappears, and the oven door assembly 100 is automatically rebounded and tightly fitted with the cavity front plate 9, ensuring the closed state of the door body; at the same time, the damper 3 in the damping buffering device 400 plays a damping buffering role, and the damping buffering head 303 first contacts the door body when the oven door assembly 100 is closed, and the damper 3 effectively slows down the closing speed of the door through the internal buffering mechanism, thereby avoiding the rapid impact of the door body on the cavity front plate 9 and ensuring the smooth and quiet closing process.

[0042] The microwave oven with a buffering device disclosed in the application is combined with the hinge device 500 and the damping buffering device 400, which not only ensures the automatic rebound and tight closing of the oven door assembly 100 when the external force is lost, but also enhances the sealing performance of the door body, effectively prevents heat leakage, and improves the cooking efficiency. The addition of the damping buffering device 400 fundamentally solves the problem of strong impact of the door body of the traditional microwave oven when closing, and the buffering effect of the damper 3 enables the oven door assembly 100 to smoothly and slowly contact the cavity front plate 9 during the closing process, avoiding the noise and wear caused by the impact, protecting the integrity of the cavity front plate and the door body surface, prolonging the service life of the microwave oven, and improving the overall quality of the product.

[0043] As a preferred example of the application, two hinge devices 500 are arranged on opposite sides of the oven cavity assembly 300, and the damping buffering device 400 is arranged near the front end of the oven cavity assembly 300. As a specific example of the application, the hinge devices 500 are arranged near the lower end of the oven cavity assembly 300, and the damping buffering device 400 is arranged at the upper end of the side of the oven cavity assembly 300 away from the panel assembly 200, thereby forming a draw-down door type microwave oven. The microwave oven of the application is provided with two hinge devices 500 and one damping buffering device 400, which realizes an efficient and stable door closing mechanism. The hinge devices 500 are arranged on both sides of the oven cavity assembly 300 near the lower end, which provides balanced support for the oven door assembly. When the user opens the oven door, the door hinge springs 7 on both hinges bear the tension at the same time, store the elastic potential energy, and enable the oven door to automatically rebound and tightly close under the action of no external force. The damping buffering device 400 is arranged at the upper end of the side of the oven cavity assembly away from the panel assembly 200, and first contacts the damping buffering head 303 when the oven door is closed. The buffering mechanism inside the damper 3 effectively slows down the closing speed of the door body, ensuring a smooth and quiet closing process.

[0044] This setting not only improves the operation convenience of the microwave oven, avoids the shaking and wear problems caused by single-point support, which makes the door body more durable in frequent use, prolongs the service life of the product, at the same time, the design of the pull-down door not only optimizes the user's use convenience, but also saves the kitchen space, makes the overall layout of the microwave oven more compact and reasonable.

[0045] As a preferred example of the present application, the damping buffer device 400 further comprises a damper lower cover 1 and a damper upper cover 2, the damper lower cover 1 is detachably connected with the damper upper cover 2 and fixes the damper 3 between them, and the damper lower cover 1 and / or the damper upper cover 2 is detachably connected with the oven cavity assembly 300. The damping buffer device 400 of the present application is designed by combining the damper lower cover 1, the damper upper cover 2 and the damper 3. In use, the damper lower cover 1 and the damper upper cover 2 fix the damper 3 through detachable connection, so that the installation and disassembly of the whole damping buffer device 400 become more convenient, and the damper 3 is detachably connected with the oven cavity assembly 300 through the damper lower cover 1 and / or the damper upper cover 2. This design not only facilitates production and assembly, but also facilitates later maintenance and replacement.

[0046] This setting optimizes the structure of the damping buffer device 400, improves the overall maintenance efficiency of the product, reduces the maintenance cost, and the user can quickly disassemble and replace the relevant parts when encountering problems, ensuring the normal operation of the microwave oven.

[0047] As a preferred example of the present application, the damper lower cover 1 comprises a first connecting plate 101 and a first containing plate 102, the damper upper cover 2 comprises a second connecting plate 201 and a second containing plate 202, the first containing plate 102 and the second containing plate 202 form a space containing the damper 3, and the first connecting plate 101 and the second connecting plate 201 are detachably connected with the side plate of the furnace cavity assembly 300 through the first connecting screw 4. As a preferred example, the first connecting plate 101 and the second connecting plate 201 are arranged in parallel and close to each other. This arrangement further optimizes the structure of the damper lower cover 1 and the damper upper cover 2. The damper lower cover 1 is composed of the first connecting plate 101 and the first containing plate 102, and the damper upper cover 2 is composed of the second connecting plate 201 and the second containing plate 202. A tight space is formed between the two, which wraps the damper 3 and provides a closed and stable working environment for the damper 3. This effectively prevents the intrusion of external impurities and dust, thereby prolonging the service life of the damper 3 and ensuring its stability and reliability during long-term use. The first connecting plate 101 and the second connecting plate 201 are arranged in parallel and close to each other, and are detachably connected with the side plate of the furnace cavity assembly 300 through the first connecting screw 4. This design makes the connection between the damper lower cover 1 and the damper upper cover 2 more secure, effectively resisting various forces and vibrations during use. At the same time, when it is necessary to install or disassemble the damping buffer device, the user only needs to simply operate the first connecting screw to complete the operation, greatly improving the convenience and efficiency of the operation, thereby realizing the quick replacement and maintenance of the damper.

[0048] As a preferred example of the present application, the first accommodating plate 102 and the second accommodating plate 202 are connected by the connection card block 203 and the connection card slot 104. In the example of the present application, the connection card slot 104 is provided on the first accommodating plate 102, and the connection card block 203 is provided on the second accommodating plate 202. When the damper 3 is placed in the packaging space surrounded by the first accommodating plate 102 and the second accommodating plate 202, the detachable assembly of the damper lower cover 1, the damper upper cover 2, and the damper 3 is achieved by the clamping connection of the connection card block 203 and the connection card slot 104. The clever design of the connection card block 203 and the connection card slot 104 of the damping and buffering device 400 of the present application achieves the stable connection of the damper lower cover 1 and the damper upper cover 2. During assembly, the user only needs to place the damper 3 in the packaging space surrounded by the first accommodating plate 102 and the second accommodating plate 202, and then align and clamp the connection card block 203 and the connection card slot 104. The connection of the damper lower cover 1, the damper upper cover 2, and the damper 3 body can be easily completed, which not only simplifies the assembly process, but also ensures the close fit between the components, making the entire device have good detachability, and the user can conveniently and quickly complete the operation when maintenance or replacement is needed, providing convenience for the use of the damping and buffering device. In addition, this design also improves the adaptability of the damping and buffering device, making it applicable to various models and specifications of microwave ovens, and widening the market application range of the product.

[0049] As a preferred example of the present application, the damper 3 includes a damping sleeve 301 and a damping slide rod 302. The damping sleeve 301 can be wrapped in the accommodating cavity surrounded by the first accommodating plate 102 and the second accommodating plate 202. The damping slide rod 302 extends outward relative to the damping sleeve 301 and protrudes out of the cavity front plate 9. The damping and buffering head 303 is provided at the front end of the damping slide rod 302. The damper 3 of the present application achieves effective buffering function through the cooperation of the damping sleeve 301 and the damping slide rod 302. Specifically, the damping sleeve 301 is cleverly wrapped in the accommodating cavity surrounded by the first accommodating plate 102 and the second accommodating plate 202, ensuring its stable installation and saving space. The damping slide rod 302 extends outward relative to the damping sleeve 301 and smoothly protrudes out of the cavity front plate 9, so that the damper 3 can contact the external structure and produce buffering. The damping and buffering head 303 is provided at the front end of the damping slide rod 302, further enhancing the buffering effect and ensuring the smooth and reliable operation of the entire damper during operation. This design not only improves the performance of the equipment, but also provides a good foundation for subsequent use.

[0050] As a preferred example of the present application, a first limiting plate 103 is arranged on the damper lower cover 1, which overlaps the upper surface of the top plate of the furnace cavity assembly 300. In the example of the present application, the damper lower cover 1 is a cover plate arranged on the damper buffer device 400 close to the furnace cavity assembly 300. As a preferred example, the first limiting plate 103 is arranged on the first connecting plate 101 below the first containing plate 102, and the first connecting plate 101 and the first limiting plate 103 are connected to the top surface and the side surface of the furnace cavity assembly 300. By arranging the first limiting plate 103 on the damper lower cover 1 of the damper buffer device 400 close to the furnace cavity assembly 300, the damper buffer device 400 is quickly positioned to the mounting position on the furnace cavity assembly 300 through the first limiting plate 103 during assembly. The first limiting plate 103 overlaps the upper surface of the top plate of the furnace cavity assembly 300, and then the damper buffer device 400 is detachably connected to the furnace cavity assembly 300 through the first connecting screw 4.

[0051] This arrangement enhances the connection stability between the damper buffer device 400 and the furnace cavity assembly 300, realizes quick positioning and detachable connection, improves the assembly efficiency, ensures the stability and reliability of the overall structure, effectively prevents displacement caused by vibration or external force, and improves the working performance and use experience of the equipment.

[0052] The hinge device 500 further comprises a roller 6 for supporting the hinge connecting rod 5 and capable of rotating when the hinge connecting rod 5 slides. In the example of the present application, a through slot 10 is arranged on the cavity front plate 9, one end of the hinge connecting rod 5 penetrates through the through slot 10 and is hingedly connected to the furnace door assembly 100, and a roller fixing seat assembly 11 is arranged on the bottom plate assembly 8 connected to the lower end of the cavity front plate 9 for supporting the hinged roller 6. When the furnace door assembly 100 is opened or closed relative to the cavity front plate 9, the hinge connecting rod 5 slides forward or backward along the through slot 10 and the roller 6. In the present application, one end of the hinge connecting rod 5 penetrates through the pre-set through slot 10 on the cavity front plate 9 and is hingedly connected to the furnace door assembly 100 through the door body pivot, and a roller fixing seat assembly 11 is arranged on the bottom plate assembly 8 at the lower end of the cavity front plate 9, which stably supports and hingedly connects the roller 6. When the furnace door assembly 100 is opened or closed relative to the cavity front plate 9, the hinge connecting rod 5 will act accordingly and smoothly slide forward or backward along the track of the through slot 10 and the support surface of the roller 6. In this process, the roller 6 not only bears the weight of the hinge connecting rod 5 and the furnace door assembly 100, but also effectively reduces the frictional resistance in the sliding process through its own rotating characteristics, making the opening and closing action of the door body more smooth and easy.

[0053] The hinge device 500 of the present application improves the flexibility and stability of the hinge connecting rod 5 in the sliding process by introducing the roller 6 design, effectively avoids the jamming or wear problem caused by excessive friction of the traditional hinge, enables the door body to maintain a more stable motion state during opening and closing, reduces the generation of noise, and improves the user experience.

[0054] As a preferred example of the present application, the hinge connecting rod 5 is designed in a whole step-shaped design, the upper connecting edge 501 of the hinge connecting rod 5 is hingedly connected with the damping device 4, the lower connecting edge 503 of the hinge connecting rod 5 is hingedly connected with the furnace door assembly 100 through the through slot 10, and the bending edge 502 provided between the upper connecting edge 501 and the lower connecting edge 503 of the hinge connecting rod 5 forms a limiting portion of the outward movement of the hinge device 500. When the furnace door assembly 100 is opened to a certain angle, the limiting portion on the hinge connecting rod 5 contacts the cavity front plate 9, thereby generating a blockage, effectively limiting the further opening of the furnace door assembly 100, avoiding the inconvenience or damage that may be caused by the excessively large opening angle of the door, and preventing the opening angle of the door from being too large.

[0055] The setting effectively prevents the door body from colliding with the surrounding objects due to excessive opening, avoids unnecessary damage, ensures the stability and reliability of the opening and closing process of the door body, guarantees the normal use of the door body, improves the overall performance and user experience of the product, and provides a safer and more convenient operation mode for the user.

[0056] As a preferred example of the present application, a second hook slot 13 is provided on the hinge connecting rod 5, a first hook slot 12 is provided on the bottom plate assembly 8, and the two ends of the door hinge spring 7 are respectively hooked in the second hook slot 13 and the first hook slot 12. This setting optimizes the assembly structure of the door hinge spring 7, the hinge connecting rod 5, and the bottom plate assembly 8. By providing the second hook slot 13 and the first hook slot 12, the assembly of the door hinge spring 7 becomes faster and more accurate, which not only greatly improves the production efficiency, but also reduces the assembly difficulty, ensures consistent quality standards during mass production, and effectively enhances the stability and reliability of the spring during long-term use, avoiding failures caused by spring loosening or falling, and further ensuring the safety of the product.

[0057] As a preferred example, the door hinge spring 7 is arranged in a backward inclined shape from top to bottom. This setting enables the door hinge spring 7 to uniformly provide assistance and buffering during the opening and closing of the door body, making the opening and closing of the door body more smooth, and enhancing the stability of the door body, thereby improving the user experience.
