Description

Technical Field

[0001] This invention relates to the field of kitchen sliding door technology, specifically to a kitchen door, system, and control method based on automatic smoke concentration control. Background Technology

[0002] Kitchen doors, as an important component of home design, are typically used to separate the kitchen from other living spaces in the home. In traditional designs, kitchen doors are mostly fixed or sliding, and are often made of wood, metal, or synthetic materials to meet the needs of durability and aesthetics. These doors offer some sound insulation, effectively preventing kitchen noise and some odors from spreading to other rooms. However, conventional kitchen door designs do not consider ease of use and hygiene, especially the practical need for convenient opening and closing of the door during cooking.

[0003] During cooking, operations such as frying and boiling often produce a large amount of fumes, causing the air quality in the kitchen to deteriorate rapidly. To prevent these fumes from leaking into the living room or other adjacent rooms, cooks usually need to keep the kitchen door closed while cooking. However, this practice not only increases the cook's workload, but also makes it inconvenient and unhygienic to operate the door handle, especially when their hands are covered in food or oil. Summary of the Invention

The first connecting shaft of the sliding door slides in the linear motion groove, and the second connecting shaft slides in the linear motion groove A, until the two first connecting shafts enter the first receiving groove and the second receiving groove respectively, and the two second connecting shafts enter the first receiving groove A and the second receiving groove A respectively. At this time, the sliding door is flush with the fixed door, and the kitchen door is closed. Beneficial effects

[0016] This invention provides a kitchen door, system, and control method based on automatic smoke concentration control; This kitchen door system, based on automatic smoke concentration control, integrates a smoke sensor and controller to achieve a smoke-concentration-based door control system that automatically adjusts the opening and closing status of the sliding door. When the smoke concentration detected by the smoke sensor exceeds a threshold set by the controller, the controller instructs the drive mechanism to move the sliding door to the closed position, effectively preventing kitchen smoke from spreading into the living area. Furthermore, when the smoke concentration drops below the threshold, the controller instructs the drive mechanism to reverse, reopening the sliding door and maintaining ventilation and air circulation in the kitchen. This automated control not only improves ease of use and avoids the inconvenience and hygiene problems associated with manual door operation, but also helps maintain indoor air quality and the comfort of the living environment.

[0017] When the kitchen door is closed, the sliding door and the fixed door form a continuous, "seamless" appearance on the same plane. This design makes the overall door look neater and more harmonious, conforming to the minimalist aesthetics of modern home design, as shown in the picture. When the kitchen door is closed, the gap between the sliding door and the fixed door is minimized, which can more effectively prevent smoke, oil vapors, and noise from the kitchen from entering other living areas, maintaining a clean and quiet home environment.

[0018] This kitchen system features an automatically controlled kitchen door based on smoke concentration. This system automatically adjusts the door's opening and closing status according to the real-time smoke levels in the kitchen. This automation not only enhances the comfort of the living environment but also strengthens safety during kitchen use. By monitoring and responding to smoke concentration in the kitchen in real time, the system ensures rapid smoke isolation when needed, effectively preventing its spread to other living areas.

[0019] In addition, the kitchen door control method can effectively adjust the opening and closing status of the kitchen door automatically according to the real-time smoke situation in the kitchen, which not only ensures the comfort of the living environment, but also improves the safety of kitchen use.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0041] Please see Figures 1 to 19 The present invention provides a kitchen door based on automatic smoke concentration control, including a door frame 1 as a supporting frame of the kitchen door structure, a fixed door 2 fixedly connected to the door frame 1, and a sliding door 3 slidably connected to the door frame 1; the door frame 1 is provided with a drive mechanism 4 for driving the sliding door 3 to slide.

[0042] The drive mechanism 4 is used to drive the sliding door 3 to slide, thereby controlling the opening or closing of the kitchen door.

[0043] Furthermore, the kitchen door also includes: A smoke sensor 6 used to detect the concentration of smoke in the kitchen; A controller 5 acquires smoke concentration data detected by the smoke sensor 6. The controller 5 is connected to the drive mechanism 4 and is used to control the operation of the drive mechanism 4.

[0044] The smoke sensor 6 is connected to the door frame 1 and is located inside the kitchen. In actual use, the smoke sensor 6 detects the smoke concentration in the kitchen. When smoke reaches the kitchen door, the smoke sensor 6 transmits the smoke concentration value to the controller 5 via an electrical signal. The controller 5 stores a smoke concentration threshold. When the smoke concentration value detected by the smoke sensor 6 exceeds the stored threshold, the controller 5 controls the drive mechanism 4 to move. The drive mechanism 4 then moves the sliding door 3 until it is flush with the fixed door 2 (e.g.,...). Figure 1 As shown), the kitchen door is closed. When the smoke concentration value is lower than the smoke concentration threshold stored in the controller 5, the controller 5 controls the drive mechanism 4 to move, and the drive mechanism 4 drives the sliding door 3 to move, as shown. Figure 2 and Figure 3 As shown, until the sliding door 3 is in the open state.

[0045] By integrating a smoke sensor 6 and a controller 5, a door control system based on smoke concentration is implemented, which can automatically adjust the opening and closing state of the sliding door 3. When the smoke concentration detected by the smoke sensor 6 exceeds the threshold set by the controller 5, the controller 5 instructs the drive mechanism 4 to actuate, moving the sliding door 3 to the closed position, effectively preventing kitchen smoke from spreading to the living area. Furthermore, when the smoke concentration drops below the threshold, the controller 5 instructs the drive mechanism 4 to reverse operation, restoring the sliding door 3 to the open state, maintaining ventilation and air circulation in the kitchen. This automated control not only improves ease of use and avoids the inconvenience and hygiene problems caused by manual door operation, but also helps maintain indoor air quality and the comfort of the living environment.

[0046] As an optional implementation, the present invention provides an automated kitchen door design with manual control functionality. The fixed door 2 is constructed with double-layered laminated glass to enhance its sound insulation and heat preservation performance, reducing noise from appliances such as range hoods heard in the living room or other rooms. An aluminum alloy support column 21 is installed on the side of the fixed door 2 near the sliding door 3, and this support column 21 is equipped with a control switch 9. This control switch 9 is electrically connected to a controller 5, and the controller 5 can operate the drive mechanism 4 to realize the opening or closing action of the sliding door 3.

[0047] To ensure the door control can automatically respond to environmental changes while also meeting individual user needs, this kitchen door features two switching modes: automatic and manual. In automatic mode, when the smoke concentration detected by the smoke sensor 6 exceeds the threshold set by the controller 5, the controller 5 automatically instructs the drive mechanism 4 to close the sliding door 3; when the smoke concentration is below the threshold, the sliding door 3 automatically opens. In manual mode, users can directly control the opening and closing of the sliding door 3 via the control switch 9, regardless of the smoke concentration.

[0048] In operation, the kitchen door is normally open in a smoke-free environment to maintain good ventilation. When the user needs to manually close the kitchen door, for example, to block sound or maintain temperature, they can press control switch 9 to send a closing command to controller 5, which in turn controls drive mechanism 4 to close the sliding door 3 against the fixed door 2. Conversely, to open the door, the user can also send an opening command using the same control switch 9, causing controller 5 to instruct drive mechanism 4 to slide the sliding door 3 open.

[0049] The control switch 9 serves as the direct interface between the user and the automated door system, allowing the user to manually control the opening and closing of the sliding door 3 according to their individual needs. The control switch 9 is electrically connected to the controller 5. When the user operates the control switch 9, the corresponding command signal is transmitted to the controller 5. For example, when the user issues a command to close the door via the control switch 9, the controller 5, upon receiving this command, will disregard the smoke concentration data from the smoke sensor 6 and directly command the drive mechanism 4 to close the door. Similarly, the command to open the door is also implemented in this way.

[0050] Furthermore, control switch 9 specifically includes a toggle switch (not shown in the figure), a kitchen door opening switch (not shown in the figure), and a kitchen door closing switch (not shown in the figure). The toggle switch is used to switch between smoke-based control and control based on the opening and closing of the kitchen door. During normal use, the opening and closing of the kitchen door is controlled by controller 5 based on the smoke concentration detected by smoke sensor 6. When the user operates the toggle switch, controller 5 can no longer control the drive mechanism 4 based on the smoke concentration detected by smoke sensor 6. Instead, it sends a command to controller 5 via the kitchen door opening switch, which then controls drive mechanism 4 to open the kitchen door. Similarly, the kitchen door closing switch sends a command to controller 5, which then controls drive mechanism 4 to close the kitchen door.

[0051] As an optional implementation, in order to improve the operational stability and efficiency of the kitchen door, the automated kitchen door system of the present invention employs two drive mechanisms 4 in its design. These two drive mechanisms 4 are respectively installed in the upper and lower parts of the door frame 1, specifically in the upper mounting cavity 11 and the lower mounting cavity 12.

[0052] This design allows the sliding door 3 to open and close more smoothly and synchronously, reducing tilting or jamming that might be caused by a single drive point. The drive mechanism 4 in the upper mounting cavity 11 is mainly responsible for the upper movement of the sliding door 3, while the drive mechanism 4 in the lower mounting cavity 12 controls the lower movement. The two work together to ensure that the overall movement of the door is more uniform and smooth. This arrangement not only improves the service life of the door but also optimizes the user's operating experience.

[0053] As an optional implementation, the sliding door 3 adopts a design that combines an aluminum alloy frame 31 and glass 32 to enhance structural stability and provide visual transparency. Specifically, the aluminum alloy frame 31 is a rectangular frame composed of four specialized aluminum alloy profiles, including two horizontally arranged first aluminum alloy profiles 311 and two vertically arranged second aluminum alloy profiles 312.

[0054] This rectangular structure design not only provides sufficient structural strength to support the central glass 32, but also ensures the overall aesthetics and practicality of the sliding door 3. The use of aluminum alloy effectively resists corrosion and maintains long-term durability, while the glass 32 brings more light and a wider view into the kitchen. Furthermore, the combination of aluminum alloy profiles facilitates glass installation and replacement, improving the overall efficiency of door maintenance and repair. Through this design, the sliding door 3 is not only practical but also matches the design aesthetics of a modern kitchen, enhancing the overall decorative effect.

[0055] As an optional implementation, the upper surface of the first aluminum alloy profile 311 located on the upper side is provided with two first connecting shafts 33, and the lower surface of the first aluminum alloy profile 311 located on the lower side is provided with two second connecting shafts 34. The bottom wall of the upper mounting cavity 11 of the door frame 1 is provided with a first sliding groove 111 and a second sliding groove 112, and the top wall of the lower mounting cavity 12 of the door frame 1 is provided with a third sliding groove 121 and a fourth sliding groove 122. The two first connecting shafts 33 pass through the first sliding groove 111 and are movably connected to the first sliding groove 111, and the two second connecting shafts 34 respectively pass through the third sliding groove 121 and are movably connected to the third sliding groove 121.

[0056] The shape of the first slide groove 111 is the same as that of the third slide groove 121, and they correspond vertically; the shape of the second slide groove 112 is the same as that of the fourth slide groove 122, and they correspond vertically. Furthermore, as... Figure 19As shown, the first slide groove 111 includes a first receiving groove 1111, a guide groove 1112, a second receiving groove 1113, and a linear motion groove 1114; the first receiving groove 1111, the guide groove 1112, the second receiving groove 1113, and the linear motion groove 1114 are interconnected to form the first slide groove 111; the second slide groove 112 is L-shaped. The third slide groove 121 includes a first receiving groove A1211, a guide groove A1212, a second receiving groove A1213, and a linear motion groove A1214; the first receiving groove A1211, the guide groove A1212, the second receiving groove A1213, and the linear motion groove A1214 are interconnected to form the third slide groove 121; the fourth slide groove 122 is L-shaped.

[0057] The two drive mechanisms 4 are linear actuators. The output ends of the two drive mechanisms 4 are respectively connected to drive blocks 7. The two drive blocks 7 are provided with drive slots 71. The two drive blocks 7 are slidably installed in the upper mounting cavity 11 and the lower mounting cavity 12 respectively.

[0058] Two first aluminum alloy profiles 311 are respectively connected to drive shafts 35, which pass through the second slide groove 112 and the fourth slide groove 122 and extend into the two drive grooves 71 respectively.

[0059] like Figure 1 As shown, when the sliding door 3 is flush with the fixed door 2, the kitchen door is closed. At this time, the two first connecting shafts 33 are located in the first receiving groove 1111 and the second receiving groove 1113 respectively, and the two second connecting shafts 34 are located in the first receiving groove A1211 and the second receiving groove A1213 respectively. When the drive mechanism 4 drives the drive block 7 to move linearly, the drive block 7 uses the drive groove 71 to drive the drive shaft 35 to move. The drive shaft 35 drives the sliding door 3 to move towards the kitchen from the side closest to the fixed door 2. At the same time, the first connecting shaft 33 located in the first receiving groove 1111 moves to the linear motion groove 1114, and the second connecting shaft 34 located in the first receiving groove A1211 moves to the linear motion groove A1214. As the drive block 7 continues to move, the drive block 7 drives the drive shaft 35 to move linearly. Subsequently, the first connecting shaft 33 located in the second receiving groove 1113 moves to the guide groove 1112, and the second connecting shaft 34 located in the second receiving groove A1213 moves to the guide groove A1212. At this time, the sliding door 3 is in the... Figure 2 and Figure 3As shown in the diagram, with the continued movement of the drive block 7, the first connecting shaft 33 located in the guide groove 1112 enters the linear motion groove 1114, and the second connecting shaft 34 located in the guide groove A1212 enters the linear motion groove A1214. At this time, the sliding door 3 is parallel to the fixed door 2. Next, the drive block 7 drives the drive shaft 35 to continue moving until the sliding door 3 overlaps with the fixed door 2, at which point the kitchen door is fully open. This structure, when the kitchen door is closed, creates a continuous, "seamless" appearance between the sliding door 3 and the fixed door 2 on the same plane. This design makes the overall door look neater and more harmonious, conforming to the minimalist aesthetics of modern home design. Figure 1 As shown. When the kitchen door is closed, the gap between the sliding door 3 and the fixed door 2 is minimized, which can more effectively prevent smoke, oil vapor and noise generated in the kitchen from entering other living areas, keeping the home environment clean and quiet.

[0060] As an optional implementation, the drive mechanism 4 includes an outer tube 41, an inner tube 42, a motor 43, and a screw 44. Both the outer tube 41 and the inner tube 42 are rectangular tubes, with the inner tube 42 installed inside the outer tube 41 to achieve a sliding function. The motor 43 is mounted at one end of the outer tube 41, and its output end is connected to the screw 44. The motor 43 drives the screw 44 to rotate, and the screw 44 passes through the outer tube 41 and is threaded into the inner tube 42, enabling the extension and retraction of the inner tube 42.

[0061] The controller 5 is electrically connected to the motor 43, and the controller 5 directly controls the start, stop, forward rotation, and reverse rotation of the motor 43. The motor 43 is a currently available servo motor, and its specific working principle and control method are well known to those skilled in the art, and will not be described in detail here.

[0062] The controller 5 controls the motor 43 to rotate, the motor 43 drives the screw 44 to rotate, the screw 44 drives the inner sleeve 42 to extend and retract relative to the outer sleeve 41, the movement of the inner sleeve 42 drives the drive block 7 to move linearly, thereby realizing the drive of the drive block 7.

[0063] The controller 5 manages the rotational speed and direction of the screw 44 by controlling the start and stop of the motor 43. As the screw 44 rotates, the inner sleeve 42 performs precise telescoping movements under the guidance of the outer sleeve 41. This telescoping movement directly drives the drive block 7 connected to one end of the inner sleeve 42 to move along a straight path, thereby realizing the opening and closing operation of the sliding door 3. The rectangular cross-section design of the outer sleeve 41 and the inner sleeve 42 not only improves the stability of the structure but also ensures the smooth telescoping of the inner sleeve 42, avoiding twisting or offset during movement.

[0064] A first roller 72 and a second roller 73 are rotatably connected to the drive block 7. The first roller 72 of the drive block 7 located in the upper mounting cavity 11 contacts the side wall of the upper mounting cavity 11, and the first roller 72 of the drive block 7 located in the lower mounting cavity 12 contacts the side wall of the lower mounting cavity 12. Contact plates 13 are respectively provided inside the upper mounting cavity 11 and the lower mounting cavity 12, and the second roller 73 contacts the contact plate 13. When the drive block 7 moves, the movement of the first roller 72 and the second roller 73 makes the linear movement of the drive block 7 more stable and smooth. It should be noted that there is a gap between the lower side of the contact plate 13 located in the upper mounting cavity 11 and the upper end of the first connecting shaft 33 and the upper drive shaft 35, and there is a gap between the upper side of the contact plate 13 located in the lower mounting cavity 12 and the lower end of the second connecting shaft 34 and the lower drive shaft 35, to avoid the contact plate 13 interfering with the movement of the first connecting shaft 33, the second connecting shaft 34, and the drive shaft 35.

[0065] As an optional implementation, the upper ends of the two first connecting shafts 33 are connected to a first mounting member 331, which is circular, and the lower surface of the first mounting member 331 is provided with first balls 332 arranged in a ring at equal intervals; the lower end of the second connecting shaft 34 is provided with a second mounting member 341, the lower surface of the second mounting member 341 is provided with second balls 342 arranged in a ring at equal intervals; a third mounting member 343 is provided on the second connecting shaft 34, and the upper surface of the third mounting member 343 is provided with third balls 344 arranged in a ring at equal intervals.

[0066] Furthermore, the first ball bearing 332 contacts the bottom wall of the upper mounting cavity 11, the second ball bearing 342 contacts the bottom wall of the lower mounting cavity 12, and the third ball bearing 344 contacts the top wall of the lower mounting cavity 12. With this structural design, during the movement of the sliding door 3, the first ball bearing 332, the second ball bearing 342, and the third ball bearing 344 roll, reducing the friction during the movement of the sliding door 3. At the same time, the first ball bearing 332, the second ball bearing 342, and the third ball bearing 344 also provide support for the sliding door 3.

[0067] As an optional implementation, the two drive shafts 35 are slidably connected to the two first aluminum alloy profiles 311 respectively; the aluminum alloy frame 31 is connected to the control mechanism 8. The control mechanism 8 includes two first springs 81, four second springs 82, a housing 83, two drive gears 84, two driven gears 85, two pull ropes 86, two handles 87, four locking blocks 88, and two spools 89.

[0068] Two first springs 81 are respectively disposed within the first aluminum alloy profile 311. The two first springs 81 are respectively connected to the two drive shafts 35, and each provides the drive shafts 35 with an elastic force extending out of the first aluminum alloy profile 311. Two pull ropes 86 are respectively connected to the two drive shafts 35. The housing 83 is connected to the second aluminum alloy profile 312. Two driving gears 84 are connected to each other via a spool 89, and two driven gears 85 are connected to each other via a spool 89. The two driving gears 84 are meshed with the two driven gears 85. The two driving gears 84 and the two driven gears 85 are rotatably mounted within the housing 83. Two handles 87 are respectively connected to the two driving gears 84. The exterior of the housing 83 is provided with a groove 831 for the handles 87 to rotate, and the handles 87 are located within the groove 831. Each pair of locking blocks 88 forms a group, and each group of locking blocks 88 is installed inside a handle 87. The handle 87 has two rectangular slots 872. Each locking block 88 has a lever 881 extending from the rectangular slot 872. Each pair of second springs 82 forms a group, and each group of second springs 82 is installed inside the handle 87, providing a resilient force to the two locking blocks 88 in each group. The resilient ends of the two second springs 82 in each group are connected to the two locking blocks 88 in each group, providing elastic force while preventing the locking blocks 88 from falling out of the handle 87. Each locking block 88 has a guide slope 882, and a groove 831 has two locking slots 832 that match the locking blocks 88.

[0069] In actual use, the first spring 81 provides elastic support for the drive shaft 35, allowing the drive shaft 35 to extend into the drive groove 71 of the drive block 7. At this time, the sliding door 3 can only move under the control of the drive mechanism 4. In case of a sudden emergency or electrical malfunction, the sliding door 3 cannot be opened. Therefore, the above structure is designed. The specific implementation is as follows: Rotating the handle 87 causes the drive gear 84 to rotate, which in turn drives the driven gear 85. The rotation of the drive gear 84 and driven gear 85 causes the spool 89 to rotate. This rotation of the spool 89 pulls the drive shafts 35 located on the upper and lower sides via the pull rope 86, causing the drive shafts 35 to retract into the first aluminum alloy profile 311. At this point, the connection between the drive shaft 35 and the drive block 7 is disconnected, and the first spring 81 is also compressed. Simultaneously, the locking block 88 extends into the locking groove 832, preventing the handle 87 from rotating. The sliding door 3 can then be manually pushed and pulled, causing the first connecting shaft 33 to move within the first slide groove 111 and the second connecting shaft 34 to move within the third slide groove 121, thus opening and closing the sliding door 3.

[0070] like Figure 1 , Figure 3 and Figure 17It is known that in an emergency, there are handles 87 located both inside and outside the kitchen, meaning that users inside and outside the kitchen can open the sliding door 3.

[0071] When it is necessary to reconnect the drive shaft 35 to the drive slot 71, slide the sliding door 3 to the closed state. At this time, two people are required, one inside the kitchen and one outside. Next, the two people will pinch the lever 881 on the two sets of latches 88 to move the latches 88 out of the slots 832. Then, the handle 87 can be rotated in the opposite direction. Under the restoring force of the first spring 81, the spool 89 will also be indirectly driven to rotate, and the handle 87 will then rotate in the reverse direction. Next, the drive shaft 35 will return to the drive slot 71, and the drive mechanism 4 can continue to control the movement of the sliding door 3 to realize the opening or closing of the kitchen door.

[0072] The present invention also provides a kitchen system, including the aforementioned kitchen door and smoke release device, wherein the kitchen door is opened or closed according to the smoke concentration in the kitchen.

[0073] Furthermore, the kitchen door is designed to automatically control the opening and closing of the sliding door 3 based on smoke concentration. The kitchen door includes a sliding door 3 and a fixed door 2, with the sliding door 3 operated by a drive mechanism 4. The kitchen door also includes a smoke sensor 6 for real-time monitoring of smoke concentration in the kitchen, and a controller 5 electrically connected to it, responsible for controlling the action of the drive mechanism 4 based on the smoke concentration data, automatically adjusting the opening and closing state of the sliding door 3. Smoke release devices include, but are not limited to, rice cookers, electric ovens, and electric frying pans. Smoke release devices may also include gas stove plates and frying pans.

[0074] The present invention also provides a method for controlling a kitchen door, comprising the following steps: Step 1. Obtain the smoke concentration in a designated space within the kitchen; First, use a smoke sensor 6 installed in the designated space within the kitchen to obtain the smoke concentration in that area. The smoke sensor 6 is responsible for detecting and recording the smoke concentration level in the kitchen air in real time.

[0075] Step 2. Control the kitchen door to open or close according to the smoke concentration; when the smoke concentration is greater than a set threshold, the kitchen door closes.

[0076] Based on the smoke concentration data acquired by smoke sensor 6 in step one, controller 5 analyzes whether this concentration value exceeds a preset threshold. If the detected smoke concentration is higher than this threshold, controller 5 issues a command to automatically close the kitchen door via drive mechanism 4 to prevent smoke from spreading to other areas outside the kitchen. If the smoke concentration is within a safe range, the kitchen door can remain open to maintain good ventilation.

[0077] Furthermore, the controller 5 controls the drive mechanism 4 to drive the drive block 7 in linear motion. The drive block 7 uses the drive groove 71 to drive the drive shaft 35. The drive shaft 35 drives the sliding door 3 towards the kitchen from the side closest to the fixed door 2. At the same time, the first connecting shaft 33 located in the first receiving groove 1111 moves to the linear motion groove 1114, and the second connecting shaft 34 located in the first receiving groove A1211 moves to the linear motion groove A1214. As the drive block 7 continues to move, it drives the drive shaft 35 in linear motion. Subsequently, the first connecting shaft 33 located in the second receiving groove 1113 moves to the guide groove 1112, and the second connecting shaft 34 located in the second receiving groove A1213 moves to the guide groove A1212. At this time, the sliding door 3 is in... Figure 2 and Figure 3 As shown in the diagram, with the continued movement of the drive block 7, the first connecting shaft 33 located in the guide groove 1112 enters the linear motion groove 1114, and the second connecting shaft 34 located in the guide groove A1212 enters the linear motion groove A1214. At this time, the sliding door 3 is parallel to the fixed door 2. Next, the drive block 7 drives the drive shaft 35 to continue moving until the sliding door 3 overlaps with the fixed door 2, at which point the kitchen door is fully open. When it is necessary to close the kitchen door, the drive block 7 uses the drive groove 71 to drive the drive shaft 35 to move. The drive shaft 35 drives the sliding door 3 to move. The first connecting shaft 33 of the sliding door 3 slides in the linear motion groove 1114, and the second connecting shaft 34 slides in the linear motion groove A1214, until the two first connecting shafts 33 respectively enter the first receiving groove 1111 and the second receiving groove 1113, and the two second connecting shafts 34 respectively enter the first receiving groove A1211 and the second receiving groove A1213. At this time, the sliding door 3 is flush with the fixed door 2, and the kitchen door is closed.

[0078] This method can effectively adjust the opening and closing of the kitchen door automatically based on the real-time smoke situation in the kitchen, ensuring both the comfort of the living environment and the safety of kitchen use.
