In the common integrated stoves with range hoods, the gas stove and range hood are often separate, and the range hood is fixed above the gas stove pot ring of the integrated stove, which occupies a large area of ​​the kitchen space and affects the aesthetics.

[0003] The popular integrated stoves today solve the above-mentioned problem. A accommodating cavity is provided in the body of the range hood corresponding to the body of the range hood. The range hood is telescopically arranged in the accommodating cavity. When the range hood is used to exhaust smoke, the body of the range hood extends out of the accommodating cavity of the body. When the range hood is not in use, the body of the range hood enters the accommodating cavity of the body.

[0004] However, the existing one-piece integrated stoves do not take into account the structural optimization design of the cover of the accommodating cavity. In actual application, the cover needs to be manually flipped before the body is raised or lowered, which increases the workload and slows down the work efficiency. When the range hood is extended from the accommodating cavity, it is easy to produce a rigid collision with the cover, generating a lot of noise, and causing scratches on the surface of the range hood, seriously affecting the user experience.

[0005] Therefore, it is necessary to improve the structure of the cover plate of the accommodating cavity to meet the above-mentioned design requirements. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] like Figures 1 to 7 As shown, this embodiment provides a cover flipping mechanism, including a lifting assembly 200 and a top cover body 300; the lifting assembly 200 can reciprocate between a retracted position and an extended position; the top cover body 300 includes a top cover frame 330, an elastic member 350 and a cover 310, the cover 310 is rotatably connected to the top cover frame 330, the elastic member 350 elastically connects the top cover frame 330 and the cover 310, the elastic member 350 is used to drive the cover 310 to move to a closed position, a roller member is rotatably connected to the cover 310, when the lifting assembly 200 is between the retracted position and the extended position, the surface of the lifting assembly 200 rolls with the roller member to push the cover 310 to rotate.

[0038] The cover plate flipping mechanism, by means of the rolling cooperation between the surface of the lifting assembly 200 and the roller, can achieve the purpose of pushing the cover plate 310 to rotate under the premise of avoiding the rigid collision between the lifting assembly 200 and the cover plate 310, thereby reducing the risk of each component being subjected to impact and minimizing the generation of noise; the elastic member 350 drives the cover plate 310, ensuring the precise cooperation between the lifting assembly 200 and the cover plate 310, and enabling the cover plate 310 to be reset in time. Through the above structural optimization design, the cover plate 310 can move synchronously with the movement of the lifting assembly 200. In this way, the flexibility of the cover plate flipping mechanism is guaranteed, the work process is simplified, the workload is reduced, and the work efficiency is improved.

[0039] In this embodiment, the lifting assembly 200 moving between the retracted position and the extended position passes through the transfer position; the roller member includes a first roller 311 and a second roller 312. When the lifting assembly 200 is located between the retracted position and the transfer position, the surface of the lifting assembly 200 rolls with the first roller 311, and when the lifting assembly 200 is located between the transfer position and the extended position, the surface of the lifting assembly 200 rolls with the second roller 312.

[0040] With the help of the setting of the first roller 311 and the second roller 312, the contact position between the roller member and the lifting component 200 is divided, and the roller handover action is completed by successively utilizing the first roller 311 and the second roller 312 to contact the surface of the lifting component 200, thereby ensuring that the cover plate 310 can smoothly complete the flipping action under the push of the lifting component 200.

[0041] In this embodiment, when the lifting assembly 200 is in the retracted position, the partial cross-sectional view of the integrated stove is as follows: Figure 2 At this time, the first roller 311 is in contact with the surface of the lifting assembly 200, and the lifting assembly 200 does not apply external force to the first roller 311, so the cover plate 310 is still maintained in the closed position.

[0042] When the lifting assembly 200 is located between the retracted position and the intermediate position, the partial cross-sectional view of the integrated stove is as shown in FIG. Figure 3 When the lifting assembly 200 moves toward the transfer position, the first roller 311 contacts the surface of the lifting assembly 200 and gradually turns over the cover plate 310 under the action of the thrust.

[0043] When the lifting assembly 200 is located at the intermediate position, the partial cross-sectional view of the integrated stove is as follows: Figure 4 When the lifting assembly 200 moves toward the extended position, the first roller 311 begins to separate from the surface of the lifting assembly 200, and the second roller 312 begins to contact the surface of the lifting assembly 200. When the lifting assembly 200 moves toward the retracted position, the second roller 312 begins to separate from the surface of the lifting assembly 200, and the first roller 311 begins to contact the surface of the lifting assembly 200.

[0044] When the lifting assembly 200 is in the extended position, the partial cross-sectional view of the integrated stove is as follows: Figure 5 At this time, the second roller 312 and the rear of the lifting assembly 200 are in close contact, which provides a buffer for the reaction force of the elastic member 350.

[0045] Continue to refer Figures 1 to 7 In other implementations of this embodiment, the roller member further includes a third roller, a fourth roller, a fifth roller, etc. The number of rollers is determined according to the surface shape of the lifting assembly 200. The purpose of setting the rollers is to ensure that when the lifting assembly 200 moves between the retracted position and the extended position, the surface of the lifting assembly 200 always rolls with at least one roller, thereby enabling the lifting assembly 200 to smoothly push the cover plate 310 and avoiding rigid collision between the lifting assembly 200 and the cover plate 310, thereby ensuring that the cover plate 310 smoothly flips with the lifting assembly 200.

[0046] The surface shape of the lifting assembly 200 and the arrangement of the rollers are determined by personnel in the field according to actual engineering practices. The specific determination method is common knowledge in the field and will not be elaborated herein.

[0047] This embodiment uses the following as an example: one end of the lifting assembly 200 has a profiling surface 210, the first roller 311 can roll with the profiling surface 210, and the second roller 312 can roll with the profiling surface 210 and the side of the lifting assembly 200. The design of setting the profiling surface 210 at the end of the lifting assembly 200 helps to improve the aesthetics of the lifting assembly 200. The above structural improvement optimizes the way in which the profiling surface 210 rolls with the roller member, improves the transition when the contact position of the roller moves from the end of the lifting assembly 200 to the side of the lifting assembly 200, avoids sudden changes in the force at the cover plate 310, avoids drastic changes in the position of the cover plate 310, reduces the probability of the lifting assembly 200 and the cover plate 310 being impacted, effectively controls the generation of noise, and thus significantly improves the user experience.

[0048] Furthermore, the contoured surface 210 includes a protruding arc surface, one end of the cover plate 310 is rotatably connected to the top cover frame 330 , and the other end is provided with a second roller 312 , and the first roller 311 is provided between the two ends of the cover plate 310 .

[0049] The above structural layout is simple and reliable, and realizes the precise layout of the positions of the first roller 311 and the second roller 312, thereby realizing the alternating rolling cooperation of the first roller 311 and the second roller 312 on the contoured surface 210, ensuring the smooth pushing of the lifting component 200 on the cover plate 310, and realizing the synchronous movement of the lifting component 200 and the cover plate 310.

[0050] In other implementations of this embodiment, the contour surface 210 may be other shapes. The specific shape of the contour surface 210 depends on the surface shape of the lifting assembly 200. As long as the handover action of the rollers can be achieved, no further details will be given here.

[0051] In this embodiment, the elastic member 350 includes a torsion spring, one end of which is connected to the cover plate 310 , and the other end of which is connected to the top cover frame 330 .

[0052] The torsion spring has a simple and reliable structure and has the advantages of low production cost, small space occupation and high working stability. It can meet the setting requirements of driving the cover 310 to move to the closed position, ensuring the long-term stable operation of the cover flipping mechanism.

[0053] Furthermore, the top cover body 300 also includes a transmission shaft 340 fixedly connected to the top cover frame 330, the cover plate 310 rotates around the axis of the transmission shaft 340, a connecting bracket 360 is fixedly connected to the cover plate 310, the connecting bracket 360 rotates with the transmission shaft 340, and a torsion spring is sleeved on the transmission shaft 340. The arrangement of the transmission shaft 340 and the connecting bracket 360 ensures that the cover plate 310 can rotate around the axis of the transmission shaft 340, and ensures that the cover plate 310 can rotate smoothly relative to the top cover frame 330. The design of the torsion spring sleeved on the transmission shaft 340 reduces the space occupied, reduces the risk of the torsion spring being accidentally offset from the initial position, and helps to improve the working stability of the cover plate flipping mechanism.

[0054] In this embodiment, the roller is made of elastic material. The roller made of elastic material helps to further reduce the impact transmitted from the lifting assembly 200 to the cover plate 310, thereby ensuring that the cover plate 310 can flip more smoothly; at the same time, the selection of elastic material helps to reduce the risk of scratches on the contoured surface 210, helps to improve the aesthetics of the lifting assembly 200, and reduces the generation of noise.

[0055] The present embodiment also provides an integrated stove, including a stove body 400, a driving device 100, a range hood device and the above-mentioned cover flipping mechanism, the top cover body 300 is fixedly connected to the stove body 400, the top cover body 300 and the stove body 400 form a receiving cavity, the range hood device includes a range hood body and a lifting assembly 200, the lifting assembly 200 is movably connected to the range hood body, the range hood body is installed in the receiving cavity, the cover 310 in the closed position closes the opening of the receiving cavity, and the driving device 100 is used to drive the lifting assembly 200 to extend or retract into the receiving cavity. Specifically, the lifting assembly 200 is a range hood head.

[0056] The integrated stove uses the design of selectively opening and closing the accommodating cavity with the help of the cover plate 310, so that the range hood device can drive the cover plate 310 to open the accommodating cavity by moving the lifting component 200 to the extended position, and then smoke can be smoked; after smoking is finished, the lifting component 200 can be placed in the accommodating cavity by moving the lifting component 200 to the retracted position, and drive the cover plate 310 to close the accommodating cavity, thereby effectively reducing the accumulation of oil stains in the accommodating cavity, improving the cleanliness of the range hood device, while also reducing the space occupied, thereby improving the user experience.

[0057] Specifically, the driving device 100 is installed in the accommodating cavity.

[0058] In this embodiment, the movement of the lifting assembly 200 between the retracted position and the extended position is driven by the driving device 100, and the movement of the cover 310 toward the closed position is driven by the elastic member 350. In other implementations of this embodiment, the driving force of the lifting assembly 200 and the cover 310 may also come from a separate motor or push rod mechanism. The specific structure is determined by the staff in this field according to the actual engineering practice and will not be elaborated here.

[0059] In this embodiment, the top cover body 300 further includes a stove plate 320, which is fixed to the top cover frame 330, and the stove body 400 includes a pot ring 410, which is arranged on the upper plate surface of the stove plate 320; when the lifting assembly 200 is in the retracted position, the cover plate 310 is flush with the stove plate 320. By limiting that the cover plate 310 can be flush with the stove plate 320, the relative position relationship between the pot ring 410 and the lifting assembly 200 is determined, so that the lifting assembly 200 can absorb the oil smoke near the pot ring 410 when it is in the extended position, and the lifting assembly 200 can reduce the occupied space as much as possible when it is in the retracted position. At the same time, the limitation that the cover plate 310 is flush with the stove plate 320 can also improve the aesthetics of the integrated stove and help improve the ability to collect oil stains on the top cover body 300.

[0060] Exemplarily, the extended position is located directly above the retracted position, and the roller member is provided on the lower plate surface of the cover plate 310. The above design optimizes the structural layout of the lifting assembly 200 and the top cover body 300, and is able to control the influence of the deadweight of the cover plate 310 on the operation of the integrated stove. The design that the extended position is located directly above the retracted position helps to simplify the activity track of the lifting assembly 200 and reduce the design difficulty of the cover plate flipping mechanism. The design that the roller member is provided on the lower plate surface of the cover plate 310 not only ensures the adhesion ability of the roller member to the surface of the lifting assembly 200, but also prevents the roller member from being exposed to the outside, thereby improving the overall aesthetics of the integrated stove.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
