Description

Technical Field

[0001] This invention relates to the technical field of kitchen electrical appliances, specifically to an opening and closing mechanism, an exhaust and drainage device, and an integrated stove. Background Technology

[0002] The integration of kitchen equipment is a new direction in the development of kitchen appliances. Integrated stoves are a typical example of integrated kitchen appliances. Integrated stoves usually combine multiple functions such as range hood, gas stove, disinfection cabinet, and storage cabinet into one unit, and have the advantages of saving space, good smoke extraction effect, low energy consumption, and energy saving and environmental protection.

[0003] Integrated cooktops that combine a cooktop and a steamer or oven function generate steam during steaming or baking. This steam typically escapes through pipes and vents on the cooktop panel. As the steam escapes, it comes into contact with the vents, producing condensation. This condensation usually collects in a collection tray below the vent. After a period of use, this tray needs to be emptied; otherwise, the accumulated condensation can cause unpleasant odors and attract insects, which is quite inconvenient. Furthermore, the vents are equipped with a cover with ventilation holes to allow steam to escape. Since these holes are always open, food scraps and residue can easily fall into the collection tray, causing contamination and negatively impacting the user experience. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the liquid collection box of the integrated stove in the prior art, which requires frequent cleaning and is very troublesome. Moreover, food residue is easy to fall into the liquid collection box, causing pollution and poor user experience. Thus, an opening and closing mechanism, exhaust and liquid drainage device and integrated stove are provided that do not require frequent cleaning, save time and effort, effectively prevent food residue from falling into the liquid collection box, and provide a good user experience.

[0013] As a preferred technical solution for the opening and closing mechanism, a locking block is provided on the second surface of the panel, and the rack slides on the locking block.

[0014] As a preferred technical solution for the opening and closing mechanism, there are two locking blocks that are spaced apart.

[0015] As a preferred technical solution for the opening and closing mechanism, at least one end of the rack has a boss, which is located on the outside of the locking block and can be engaged with the locking block.

[0016] As a preferred technical solution for the opening and closing mechanism, it further includes at least one limiting member for restricting the closed position of the cover plate, which is disposed on the inner edge of the through hole, and the limiting member extends in a direction parallel to the panel.

[0017] As a preferred technical solution for the opening and closing mechanism, a mounting frame is provided on the inner edge of the through hole, and the limiting member is provided on the mounting frame.

[0018] As a preferred technical solution for the opening and closing mechanism, multiple cover plates are provided, which are arranged side by side and cover the through hole when closed. Each cover plate has the first gear on the side facing the rack.

[0019] A venting and draining device includes the aforementioned opening and closing mechanism and a bottom shell. The panel of the opening and closing mechanism covers the bottom shell, and a draining and collecting assembly is provided on the bottom shell. The draining and collecting assembly is located below the through hole of the panel.

[0020] As a preferred technical solution for the venting and draining device, the draining assembly includes a drain box, which is fixedly connected to the bottom shell. The opening of the drain box faces the through hole and its diameter matches that of the through hole. The drain box has an air inlet and a drain outlet.

[0021] As a preferred technical solution for the venting and draining device, the opening edge of the liquid container abuts against the second surface of the panel.

[0022] As a preferred technical solution for the venting and draining device, the drain hole is located at the bottom of the liquid container and is connected to the drainage pipe.

[0023] An integrated stove includes the aforementioned exhaust and drainage device.

[0024] As a preferred technical solution for integrated stoves, the opening side of the cover plate of the opening and closing mechanism in the exhaust and drainage device is positioned away from the stove hole of the integrated stove.

[0025] The technical solution of this invention has the following advantages:

[0026] (1) The opening and closing mechanism provided by the present invention includes a panel, a cover plate, and a rotating component. The cover plate can open / close the through hole on the panel under the control of the rotating component. This opening and closing mechanism can open or close the through hole on the panel according to the usage needs, which is convenient for users to operate. For example, the through hole can be opened when steam needs to be discharged, and closed when steam does not need to be discharged, so as to prevent foreign objects such as kitchen waste from falling into the through hole, thereby meeting different user needs and improving the user experience.

[0027] (2) The opening and closing mechanism provided by the present invention includes a rotating component comprising a rack and a first gear that mesh with each other. The rack is slidably connected to the second surface of the panel, and the first gear is disposed on the side of the cover plate facing the rack. The rotating component has a simple structure, is easy to implement, and can control the opening angle of the cover plate, making it highly operable.

[0028] (3) The opening and closing mechanism provided by the present invention includes a drive component in the rotating component. The drive component is preferably a motor.

[0029] (4) The opening and closing mechanism provided by the present invention has a boss at at least one end of the rack, which can engage with the snap fastener on the second surface of the panel to limit the sliding distance of the rack, prevent the rack from coming out of the snap fastener, and improve the reliability of the structure.

[0030] (5) The opening and closing mechanism provided by the present invention also includes a limiting member for limiting the closed position of the cover plate. When the cover plate is in the closed state, the cover plate falls on the limiting member to prevent the cover plate from falling further, thereby limiting the closed position of the cover plate, making the product structure more stable and reliable, and meeting the user's needs.

[0031] (6) The opening and closing mechanism provided by the present invention includes multiple cover plates arranged in parallel and covering the through hole when closed, thereby optimizing the product structure and making the product appearance more beautiful and neat.

[0032] (7) The exhaust and drainage device provided by the present invention includes the opening and closing mechanism provided by the present invention, which can open or close the panel through hole according to the use needs, making it convenient for users to operate. For example, the through hole can be opened when steam needs to be discharged, and closed when steam does not need to be discharged, so as to prevent foreign objects such as kitchen waste from falling into the through hole, thereby meeting different user needs and improving the user experience. Moreover, since the liquid box has a drain hole at the bottom, the steam condensate can be discharged in time, without having to pour out the accumulated liquid in the liquid box or frequently clean the liquid box, saving time and effort, and also reducing the generation of odors or the breeding of mosquitoes, thus improving the user experience.

[0033] (8) The integrated stove provided by the present invention includes the exhaust and liquid draining device of the present invention, which can open or close the panel through hole as needed, that is, open the through hole when steam needs to be discharged, and close the through hole when steam does not need to be discharged, so as to prevent foreign objects such as kitchen waste from falling into the through hole. It is highly flexible in use, and there is no need to clean the liquid collection box frequently, which saves time and effort, is convenient for users, and provides a good user experience.

Detailed Implementation

[0046] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 or an electrical 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 invention according to the specific circumstances.

[0049] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] like Figure 1-3The diagram shows a preferred embodiment of the opening and closing mechanism of the present invention. This opening and closing mechanism can be applied to integrated stoves, specifically to the exhaust and drainage device of the integrated stove. It can open the through hole when exhaust is needed to allow steam to escape smoothly, and close the through hole when exhaust is not needed, thereby effectively preventing food residue from falling into the liquid collection box. Moreover, the steam condensate can be automatically discharged, eliminating the need to empty the accumulated liquid or frequently clean the liquid collection box, saving time and effort, and significantly improving the user experience.

[0051] The opening and closing mechanism includes a panel 1, a cover plate 2, and a rotating assembly. The panel 1 is a flat plate, typically arranged horizontally, and has a through hole 101 formed thereon. In this embodiment, the through hole 101 is formed near the edge of the panel 1, making the through hole 101 a U-shaped hole. The panel 1 has a first surface and a second surface. In this embodiment, since the panel 1 is placed horizontally, its first surface is its upper surface, and its second surface is its lower surface.

[0052] A cover plate 2 is rotatably disposed on the first surface of the panel 1, specifically, on the upper surface of the panel 1. The cover plate 2 can open / close the through hole 101. The size of the cover plate 2 matches the size of the through hole 101. When the cover plate 2 is in the open state, it can open the through hole 101, allowing the through hole 101 to communicate with the outside. When the cover plate 2 is in the closed state, it can close the through hole 101, preventing the through hole 101 from communicating with the outside, thereby realizing the opening and closing of the through hole 101. Preferably, multiple cover plates 2 are provided, arranged side by side, and covering the through hole 101 when closed. In this embodiment, three cover plates 2 are provided, arranged side by side, and can be opened and closed simultaneously, realizing the control of opening and closing of the through hole 101.

[0053] Furthermore, the cover plate 2 has pivot holes 201 at both ends, and a mounting frame 11 is provided on the through hole 101. A pivot is provided at the corresponding position of the mounting frame 11. The pivot is inserted into the pivot hole 201 and can rotate within the pivot hole 201, thereby realizing the rotation of the cover plate 2.

[0054] The rotating assembly is connected to the panel 1 and the cover plate 2, and is used to drive the cover plate 2 to rotate. In this embodiment, as shown... Figure 4 As shown, the rotating assembly includes a rack 3 and a first gear 4 that mesh with each other. The length direction of the rack 3 is perpendicular to the axial direction of the rotation shaft of the cover plate 2. The rack 3 is slidably connected to the second surface of the panel 1. Furthermore, the lower surface of the panel 1 is detachably provided with a locking block 7, and there are two locking blocks 7, which are spaced apart. The locking block 7 has a slot, and the rack 3 is adapted to be inserted into the slot and can slide within the slot. The first gear 4 is provided on the side of the cover plate 2 facing the rack 3, that is, the first gear 4 is fixedly connected to the lower surface of the cover plate 2. In this embodiment, each cover plate 2 has a first gear 4 on the side facing the rack 3.

[0055] In this embodiment, the rotating assembly further includes a driving component that drives the rack 3 to slide along the slot. Specifically, the driving component is a motor 5, and the output shaft of the motor 5 is provided with a second gear 6, which meshes with the rack 3. The upper surface of the motor 5 is detachably connected to the lower surface of the panel 1, and the second gear 6 is coaxially fixed on the output shaft of the motor 5.

[0056] like Figure 9 As shown, the first end face of the rack 3 is formed with a first tooth profile 301, which meshes with the first gear 4. The second end face of the rack 3 is formed with a second tooth profile 302, which meshes with the second gear 6. Specifically, the upper end face of the rack 3 is formed with the first tooth profile 301, which meshes with the first gear 4, and the lower end face of the rack 3 is formed with the second tooth profile 302, which meshes with the second gear 6. To save machining steps, the length of the second tooth profile 302 is less than the length of the first tooth profile 301. In addition, at least one end of the rack 3 has a boss 303, which is located outside the locking block 7 and can engage with the locking block 7. In this embodiment, both ends of the rack 3 have protrusions 303. After the rack 3 is assembled with the snap-fit ​​block 7, the protrusions 303 are placed on the outside of the snap-fit ​​block 7. During the sliding process of the rack 3, when the protrusions 303 come into contact with the snap-fit ​​block 7, the rack 3 can no longer slide in the original direction and can only slide in the opposite direction, thereby achieving the limitation of the rack 3.

[0057] Furthermore, in this embodiment, by adjusting the tooth spacing between the first tooth profile 301 of the rack 3 and the first gear 4, the opening angle of the cover plate 2 is ≤60°.

[0058] Furthermore, the opening and closing mechanism of this embodiment also includes at least one limiting member 8 for restricting the closed position of the cover plate 2. The limiting member 8 is disposed on the inner edge of the through hole 101 and extends in a direction parallel to the panel 1. Specifically, the limiting member 8 is disposed on the mounting frame 11, and four limiting members 8 are disposed, with each pair corresponding to the opposite sides of the mounting frame 11. When the cover plate 2 is in the closed state, the lower surface of the cover plate 2 overlaps with the limiting member 8, preventing the cover plate 2 from rotating further downward, thereby limiting the closed position of the cover plate 2.

[0059] like Figure 5-8As shown, this embodiment also provides a venting and draining device, including the opening and closing mechanism of this embodiment and a bottom shell 9. A panel 1 covers the bottom shell 9, and a draining and venting assembly is provided on the bottom shell 9, positioned below the through hole 101 of the panel 1. Specifically, the draining and venting assembly includes a liquid container 10, which is fixedly connected to the bottom shell 9. Further, the bottom of the liquid container 10 is detachably and fixedly connected to the bottom shell 9. The opening of the liquid container 10 faces the through hole 101, and preferably, the opening diameter of the liquid container 10 matches the through hole 101.

[0060] The opening edge of the liquid container 10 abuts against the second surface of the panel 1 to prevent steam and liquid from overflowing. The rotating component of the opening and closing mechanism is located within the range enclosed by the opening edge of the liquid container 10 to ensure that the cover 2 can be opened and closed smoothly.

[0061] The liquid container 10 has an air inlet 1001 and a drain hole 1002. The air inlet 1001 is located on the side wall of the liquid container 10 and protrudes outward for easy connection with a steam pipe. The drain hole 1002 is located at the bottom of the liquid container 10 and is connected to a drain pipe 12. Furthermore, the drain hole 1002 is assembled with a drain pipe connector 13. One end of the drain pipe 12 is connected to the drain pipe connector 13, and the other end of the drain pipe 12 is connected to a drain pipe, thereby discharging the liquid flowing into the liquid container 10 into the drain network, preventing the liquid from accumulating in the liquid container 10, eliminating the need for frequent emptying and cleaning of the liquid container 10, and making it convenient for users.

[0062] This embodiment also provides an integrated stove, including the exhaust and drainage device of this embodiment, which can open or close the panel through hole as needed. That is, the through hole is opened when steam needs to be discharged, and closed when steam does not need to be discharged, so as to prevent foreign objects such as kitchen waste from falling into the through hole. It is highly flexible in use, and there is no need to clean the liquid collection box frequently, which saves time and effort, is convenient for users, and provides a good user experience.

[0063] Furthermore, the integrated stove panel 1 also has a stove hole 102 for setting the gas stove head. The opening side of the cover plate 2 is set away from the stove hole 102, which further ensures that no debris will enter the liquid collection box 10 from the opening side of the cover plate 2 when the cover plate 2 is opened. Moreover, when steam is discharged through the through hole 101, the steam will not spray towards the user, ensuring personal safety.

[0064] To facilitate understanding, the working process of the exhaust and drainage device of the integrated stove in this embodiment will be described below with reference to the accompanying drawings:

[0065] When the oven or steamer of the integrated stove needs to exhaust steam, the steam first enters the liquid collection box 10 through the air inlet 1001, controlling the motor 5 to rotate the second gear 6 (in... Figure 5 From this perspective, the second gear 6 rotates clockwise at this time, causing the rack 3 to slide. Figure 5 From the perspective of the viewpoint, rack 3 is sliding to the right at this time, and the first gear 4 is rotating. Figure 5 From this perspective, the first gear 4 rotates counterclockwise, causing the cover plate 2 to open upwards, thereby opening the through hole 101 and allowing steam to escape. At the same time, a small amount of steam condenses and flows downwards through the cover plate 2 back to the liquid container 10, and then is discharged from the drain hole 1002.

[0066] When the integrated cooktop's oven or steamer does not require exhaust, the control motor 5 causes the second gear 6 to rotate (in... Figure 7 From this perspective, the second gear 6 rotates counterclockwise, causing the rack 3 to slide. Figure 7 From the perspective of the viewpoint, rack 3 is sliding to the left, and the first gear 4 is rotating. Figure 7 From this perspective, the first gear 4 rotates clockwise, causing the cover plate 2 to close downwards, thereby closing the through hole 101. When the user is cooking, kitchen residue will not enter the through hole 101, preventing the liquid container 10 from being contaminated and improving the user experience.

[0067] In other embodiments, the number of cover plates 2 can be one, two, four, etc., which can also achieve the purpose of the present invention, and the present invention does not limit this.

[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
