Description

Technical Field

[0001] This invention relates to the field of door technology for electrical products, and particularly to a door structure and an oven. Background Technology

[0002] Microwave ovens, ovens, and other similar appliances typically have doors on either side of the opening of the cavity, which are used to open and close the cavity. However, the current door designs are flawed; the doors can only stop at their maximum opening angle, limiting their functionality and failing to meet users' needs for wider opening angles, thus hindering market competitiveness. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a door structure that allows the door to hover between the closed position and the maximum opening angle position, meeting users' needs for more opening angles and improving the user experience.

[0004] The present invention also proposes an oven having the above-described door structure.

[0005] According to a first aspect of the present invention, a door structure includes a body, two doors, two connecting rods, and a damping device. The body has a receiving cavity and an opening communicating with the receiving cavity; the two doors are rotatably disposed on opposite sides of the opening, and the two doors can cooperate to open and close the opening; the two connecting rods are hinged to the two doors; the damping device includes two damping plates and a first damping element, the two damping plates are hinged to the ends of the two connecting rods away from the doors, and the damping plates can move with the connecting rods; the first damping element is mounted on the body and located between the two damping plates, wherein a driving structure is provided between the two damping plates, or between the damping plates and the body, the driving structure enabling the two damping plates to move closer together so that the damping plates abut against the first damping element.

[0006] The door structure according to embodiments of the present invention has at least the following beneficial effects: the drive structure can bring the two damping plates closer together, thereby causing the two damping plates and the first damping member to abut against each other and generate damping. During the process of the door rotating to open or close, the door drives the connecting rod to move, and the connecting rod drives the damping plates to move. The damping generated between the two damping plates and the first damping member can form a resistance when the connecting rod moves, thereby allowing the door to hover between the closed position and the maximum open position. When the user rotates the door to the desired opening angle and stops operating the door, under the action of this damping, the door can hover at the desired opening angle position. In this way, more opening angle requirements of the user can be met, improving the user experience. In addition, during the opening and closing process, the damping generated by the two damping plates and the first damping member abutting against each other can reduce the rotation speed of the door, thereby reducing the impact force between the door and the machine body, protecting the door and the machine body, and improving the service life of the product.

[0012] According to some embodiments of the present invention, the outer periphery of the first damping member is provided with a first guide groove, the damping plate is inserted into the first guide groove, and / or the outer periphery of the third damping member is provided with a second guide groove, the second elastic strip is inserted into the second guide groove.

[0013] According to some embodiments of the present invention, two third damping elements are provided, and the two third damping elements abut against the two second elastic strips in a one-to-one correspondence. One first damping element is provided, and the two third damping elements and the first damping element are distributed in a triangular pattern.

[0014] According to some embodiments of the present invention, the damping device further includes a fixing plate, which is connected to two of the third damping elements and the first damping element.

[0015] An oven according to a second aspect embodiment of the present invention includes the door structure described above.

[0016] The oven according to the embodiments of the present invention has at least the following beneficial effects: With the above-mentioned settings, the oven door can be suspended between the closed position and the maximum opening angle position, which can meet the user's needs for more opening angles and improve the user experience; in addition, during the opening process, the door can be rotated to open part of it first, releasing some of the hot air inside the oven before fully opening the door, which can alleviate the hot air rushing out during the opening process and reduce the risk of burns.

[0033] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0034] Reference Figure 1 , Figure 2 , Figure 6 and Figure 8 According to a first aspect embodiment of the present invention, a door structure includes a body 100, two door bodies 200, two connecting rods 310, and a damping device 400. The body 100 is provided with a receiving cavity 110 and an opening 120 communicating with the receiving cavity 110, the receiving cavity 110 being used to place items or food; the two door bodies 200 are rotatably disposed on opposite sides of the opening 120, and the two door bodies 200 can cooperate to open and close the opening 120; the two connecting rods 310 are hinged to the two door bodies 200 respectively; the damping device 400 includes two damping plates 420 and a first damping element 410, the two damping plates 420 being hinged to the two connecting rods 310 respectively. The end of the 10 away from the door body 200 is hinged, and the damping plate 420 can move with the connecting rod 310. The first damping element 410 is installed on the body 100 and is located between the two damping plates 420. A driving structure 460 is provided between the two damping plates 420, or a driving structure 460 is provided between the damping plate 420 and the body 100. The driving structure 460 can bring the two damping plates 420 closer together so that the damping plate 420 abuts against the first damping element 410.

[0035] The drive structure 460 can bring the two damping plates 420 closer together, so that the two damping plates 420 and the first damping element 410 abut against each other to generate damping. During the process of the door 200 rotating to open or close, the door 200 drives the connecting rod 310 to move, and the connecting rod 310 drives the damping plates 420 to move. The damping generated between the two damping plates 420 and the first damping element 410 can form a resistance when the connecting rod 310 moves, thereby making the door 200 hover between the closed position and the maximum open position. The user can then open the door 200. When the door 200 is rotated to the desired opening angle and the operation is stopped, the door 200 can be suspended at the desired opening angle under the action of the damping. This can meet the user's needs for more opening angles and improve the user experience. In addition, during the opening and closing process, the damping generated by the two damping plates 420 and the first damping element 410 can reduce the rotation speed of the door 200, thereby reducing the impact force between the door 200 and the machine body 100, protecting the door 200 and the machine body 100, and improving the service life of the product.

[0036] In specific implementation, the drive structure 460 can adopt various implementation methods, for example: refer to Figure 1 and Figure 2 In some embodiments, the drive structure 460 may include a first elastic element, which may be disposed between two damping plates 420, and more than one first elastic element may be disposed. The tension of the first elastic element causes the two damping plates 420 to move closer together. Alternatively, the first elastic element may be disposed between the body 100 and each damping plate 420, and the tension or extension of the first elastic element causes the two damping plates 420 to move closer together relative to each other. In other embodiments, the drive structure 460 may also include a first magnet mounted on the damping plate 420 and a second magnet mounted on the body 100. The repulsive force generated by the interaction of the first magnet and the second magnet causes the two damping plates 420 to move closer together relative to each other.

[0037] In the specific implementation process, the damping magnitude between the damping plate 420 and the first damping element 410 can be adjusted by replacing or adjusting the drive structure 460, thereby achieving a good hovering effect and enabling the door 200 to hover at at least one angle position between the closed position and the maximum opening angle position.

[0038] Reference Figure 1 and Figure 2 In the specific implementation process, a portion of the first damping member 410 and the damping plate 420 is located between the connecting rod 310 and the door body 200, or a portion of the first damping member 410 and the damping plate 420 is located on the side of the connecting rod 310 away from the door body 200.

[0039] Reference Figures 2 to 4 It is conceivable that in some embodiments, the damping plate 420 has a locking position 421 on its side near the first damping member 410. The first damping member 410 can engage with the locking position 421. The locking position 421 can be a groove directly provided on the damping plate 420, or it can be defined by two arched portions provided on the damping plate 420. When the user rotates the door 200 to a position where the first damping member 410 and the locking position 421 engage, the user needs to exert more force to continue rotating the door 200 to disengage the first damping member 410 from the locking position 421, thus achieving a stopping effect. Through the setting of the locking position 421, the door 200 can be accurately stopped at a preset position during the opening process. More than one locking position 421 can be provided; the specific number and location can be determined according to design requirements.

[0040] Reference Figures 2 to 4Specifically, in some embodiments, the first damping member 410 is located between the connecting rod 310 and the door 200. In this case, the damping plate 420 is partially located on the side of the connecting rod 310 closer to the door 200. Each damping plate 420 has two locking positions 421. One locking position 421 is located in the middle or near the middle of the damping plate 420. When the door 200 rotates relative to the opening 120 to the transition opening position, this locking position 421 engages with the first damping member 410. The other locking position 421 can also be located in the middle or near the middle of the damping plate 420, i.e., the two locking positions 421 are arranged adjacently, thus forming two adjacent transition opening positions. When opening the oven door 200, the door 200 can be rotated to one of the transition opening positions first to release some of the hot air inside the oven before fully opening the door 200. This can alleviate the hot air rushing out during the opening process and reduce the risk of burns. In addition, during the closing process, when the door body 200 passes through the transition opening position, the first damping element 410 and the locking position 421 can reduce the rotation speed of the door body 200, preventing the door body 200 from closing at the doorway at a high speed, thereby reducing the impact force between the door body 200 and the machine body 100 and improving the service life of the door. Among them, the deceleration and buffering effect is better in the two adjacent transition opening positions.

[0041] It is conceivable that, in the specific implementation process, another locking position 421 can also be located at the end of the damping plate 420 away from the door body 200. When the door body 200 rotates close to the maximum opening angle position, the locking position 421 engages with the first damping member 410. Thus, when the door body 200 rotates close to the maximum opening angle position, the first damping member 410 engages with the locking position 421 away from the door body 200, forming a stop position, preventing the door body 200 from continuing to rotate and open, colliding with the machine body 100, and reducing the impact force between the door body 200 and the machine body 100.

[0042] In some embodiments, reference is made to Figure 6 and Figure 7 The transitional door opening position can be between 20 and 50 degrees, that is, when the first damping element 410 engages with the locking position 421 near the door body 200, the door body 200 rotates to open at an angle between 20 and 50 degrees; see reference. Figure 8 and Figure 9 In some embodiments, the maximum angle at which the door 200 can be rotated open can be between 100 and 120 degrees.

[0043] Reference Figure 2 and Figure 5It is conceivable that in some embodiments, the damping device 400 further includes a second damping element 430, the body 100 is provided with a slide groove 130, the second damping element 430 is slidably disposed in the slide groove 130, and the second damping element 430 abuts against the inner wall of the slide groove 130, and the connecting rod 310 is hinged to the second damping element 430. Therefore, the cooperation between the second damping element 430 and the slide groove 130 can guide the end of the connecting rod 310 away from the door body 200, ensuring that the connecting rod 310 and the two damping plates 420 move smoothly and steadily. The second damping element 430 abutting against the inner wall of the slide groove 130 can also generate damping. Thus, the damping device 400 can provide damping including the damping generated between the damping plate 420 and the first damping element 410, and the damping generated between the second damping element 430 and the inner wall of the slide groove 130. In this way, the damping device 400 has sufficient damping to ensure that the door body 200 can be suspended. At the same time, it can reduce the tension of the first elastic element, thereby avoiding excessive tension of the first elastic element from affecting the assembly of the damping plate 420, reducing the assembly difficulty, and also reducing the interaction force between the damping plate 420 and the first damping element 410, thereby reducing the damage to the damping plate 420 and the first damping element 410 during the rotation of the door body 200, and improving the service life of the damping device 400. Furthermore, through the transmission action of the connecting rod 310 and the second damping element 430, during use, only one door body 200 needs to be rotated while the other door body 200 rotates synchronously, facilitating the opening and closing of the door bodies 200. Of course, both door bodies 200 can also be rotated simultaneously during the opening or closing process.

[0044] Among them, reference Figure 2 and Figure 5 When the first damping member 410 is located between the connecting rod 310 and the door body 200, since the first damping member 410 is just located in the moving direction of the second damping member 430, the first damping member 410 can also play a limiting role, limiting the moving range of the second damping member 430, thereby limiting the maximum angle at which the door body 200 rotates and opens.

[0045] During the rotation of the door 200, the damping generated between the damping plate 420 and the first damping member 410 changes with the rotation of the door 200, while the damping generated between the second damping member 430 and the inner wall of the slide groove 130 does not change with the rotation of the door 200. In this way, it can be ensured that the door 200 is suspended between the closed position and the maximum open position.

[0046] Reference Figure 5 It is conceivable that, in some embodiments, the two opposite side walls of the second damping member 430 are provided with a plurality of elastic, smooth protrusions 431, which abut against the inner wall of the groove 130.

[0047] Refer to 2 to Figure 4As can be imagined, in some embodiments, the damping plate 420 has a first elastic strip 422 and a second elastic strip 423. The sidewall of the first elastic strip 422 abuts against the first damping member 410, and the second elastic strip 423 is located on the side of the first elastic strip 422 away from the first damping member 410. The damping device 400 also includes a third damping member 440, which is installed on the body 100. The second elastic strip 423 abuts against the sidewall of the first elastic strip 422. The drive structure 460 includes a first elastic member, and the two ends of the first elastic member are connected to the two second elastic strips 423 one by one. Thus, the two damping plates 420 are brought closer together by the tension of the first elastic member, thereby causing the two first elastic strips 422 to abut against the first damping member 410 to generate damping, and at the same time causing the two second elastic strips 423 to abut against the corresponding third damping member 440 to generate damping. With the above settings, the damping magnitude of the damping device 400 can be increased without increasing the tension of the first elastic element, thereby avoiding excessive tension of the first elastic element affecting the assembly of the damping plate 420. At the same time, the tension of the first elastic element can be distributed to the first damping element 410 and the third damping element 440. In this way, damage to the damping plate 420, the first damping element 410 and the third damping element 440 during the rotation of the door 200 can be reduced, and the service life of the damping device 400 can be improved.

[0048] Reference Figure 2 and Figure 4 As can be imagined, in some embodiments, the outer periphery of the first damping member 410 is provided with a first guide groove 411, and the damping plate 420 is inserted into the first guide groove 411. The first guide groove 411 allows the first damping member 410 to guide the damping plate 420, and the inner wall of the first guide groove 411 can restrict the up-and-down fluctuation of the damping plate 420, thus making the movement of the damping plate 420 more stable and smooth.

[0049] Reference Figure 2 and Figure 4 It is conceivable that, in some embodiments, the outer periphery of the third damping member 440 is provided with a second guide groove 441, and the second elastic strip 423 is inserted into the second guide groove 441. The second guide groove 441 allows the third damping member 440 to guide the damping plate 420, and the inner wall of the second guide groove 441 can restrict the up-and-down movement of the damping plate 420, thus making the movement of the damping plate 420 smoother and more stable. It is easy to imagine that, in specific implementations, the damping plate 420 can be provided with both the first guide groove 411 and the second guide groove 441, or only one of the first guide groove 411 and the second guide groove 441 can be provided.

[0050] Reference Figure 2 and Figure 4As can be imagined, in some embodiments, there are two third damping elements 440, which abut against two second elastic strips 423 in a one-to-one correspondence. There is one first damping element 410. The two third damping elements 440 and the first damping element 410 are arranged in a triangle to ensure that the first elastic strip 422 can abut against the first damping element 410 well and the second elastic strip 423 can abut against the corresponding third damping element 440 well. At the same time, it can also make the damping plate 420 move more smoothly and steadily, and ensure that the damping device 400 can make the door 200 hover normally.

[0051] Reference Figure 2 and Figure 4 As can be imagined, in some embodiments, the damping device 400 further includes a fixing plate 450, which is connected to two third damping elements 440 and to a first damping element 410. In this way, the fixing plate 450 can fix the two third damping elements 440 and the first damping element 410 together, which can improve the installation firmness of the three, ensure the stable operation of the three during long-term use, and improve the service life of the damping device 400.

[0052] Among them, reference Figure 2 and Figure 4 The first damping element 410 includes a first elastic pulley and a first mounting post. The first mounting post is mounted on the machine body, and the first elastic pulley is rotatably mounted on the first mounting post. The first guide groove 411 is provided on the first elastic pulley, and the first guide groove 411 is arranged in a ring along the circumference of the first elastic pulley.

[0053] Among them, reference Figure 2 and Figure 4 The third damping element 440 includes a second elastic pulley and a second mounting post. The second mounting post is mounted on the body 100, and the second elastic pulley is rotatably mounted on the second mounting post. The second guide groove 441 is provided on the second elastic pulley, and the second guide groove 441 is arranged in a ring along the circumference of the second elastic pulley.

[0054] Reference Figures 1 to 3It is conceivable that, in some embodiments, a second elastic element 320 is provided between the body 100 and the connecting rod 310. The second elastic element 320 is located on the side of the connecting rod 310 that is away from the door body 200. The second elastic element 320 is a tension spring or a pull rope. The tension of the second elastic element 320 can make the connecting rod 310 tend to return to its original position, ensuring that the door body 200 can close normally. One of the connecting rods 310 and the body 100 is connected to one end of the second elastic element 320, and the other is provided with multiple first mounting positions 311. The other end of the second elastic element 320 is installed in one of the first mounting positions 311 to adjust the tension of the second elastic element 320 so that the tension of the second elastic element 320 is appropriate, avoiding the second elastic element 320 being too strong and affecting the rotation and opening of the door body 200, or the second elastic element 320 being too weak and not playing its role. The first mounting position 311 can be configured as a mounting hole or a hook, and the end of the second elastic element 320 has a hook that can hook the mounting hole or the hook.

[0055] Reference Figure 1 , Figure 6 and Figure 8 The oven provided in the second aspect embodiment of the present invention includes the door structure described above. With the above configuration, the oven door 200 can hover between the closed position and the maximum opening angle position, satisfying users' needs for more opening angles and improving user experience. Furthermore, during the opening process, the door 200 can be partially rotated open to release some of the hot air inside the oven before fully opening the door 200. This can mitigate the outflow of hot air during the opening process and reduce the risk of burns.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above with reference to the accompanying drawings have been described in detail. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
