Description

Technical Field

[0001] This invention relates to the field of drainage pull-out basket technology, specifically to an intelligent automatic drainage pull-out basket for kitchen cabinets. Background Technology

[0002] In existing technologies, pull-out baskets are commonly used to store tableware and kitchen utensils, but traditional pull-out baskets suffer from poor drainage and insufficient mold prevention. When wet tableware is placed in the basket, moisture easily accumulates at the bottom, leading to bacterial growth and mold, affecting hygiene and the lifespan of the tableware. Furthermore, existing pull-out baskets lack a stable locking mechanism when closed, making them prone to accidental ejection due to external force or vibration, causing inconvenience. Although some pull-out baskets are designed with simple drainage structures, they cannot effectively promote airflow and cannot fundamentally solve the mold problem. Therefore, there is an urgent need for a smart pull-out basket that can automatically drain water, prevent mold, and ensure stable closure. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent kitchen cabinet automatic drainage pull-out basket, which solves the problems mentioned above.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent kitchen cabinet automatic drainage pull-out basket, comprising a pull-out basket body and a side plate fixed to the side of the pull-out basket body. A lower guide plate is fixedly connected to the lower part of the pull-out basket body. An elastic airbag is fixedly connected to the left side of the lower guide plate. A one-way air inlet is provided on the surface of the elastic airbag. An air nozzle facing the drain basket of the pull-out basket body is provided on the right side of the elastic airbag. A top rod is fixedly connected to the left side of the elastic airbag via a rigid plate. A piston rod is fixedly connected to the bottom of the pull-out basket body. A snap-fit ​​groove for engaging with the moving end of the piston rod is provided on the surface of the top rod. A handle is fixedly connected to the side of the side plate. A snap plate is slidably connected to the inner cavity of the handle. One side is fixedly connected to the moving end of the piston rod via a pull rope. When the pull-out basket is closed, the side panel is pushed inward, and the top rod is pressed into the cabinet, compressing the elastic airbag. The gas in the elastic airbag is blown out from the air nozzle towards the pull-out basket, creating airflow to prevent internal mold growth. The airflow also accelerates the removal of water from the lower guide plate. After the top rod reaches its limit, the moving end of the piston rod extends and engages in the engagement groove, limiting the top rod and compressing the elastic airbag to prevent it from expanding and pushing the pull-out basket out of the cabinet. When the pull-out basket is pulled out, the buckle is pulled, which pulls the pull rope and causes the moving end of the piston rod to retract. At this point, the top rod loses its limit and the elastic airbag resets.

[0005] As a further embodiment of the present invention: a water receiving box is slidably connected to the bottom of the lower guide plate, and protruding ends are provided on both sides of the water receiving box. A sliding rod that is slidably connected to the protruding ends is fixedly connected to the side of the lower guide plate. The water flowing from the lower guide plate is stored in the water receiving box, and the water receiving box can be easily removed for processing.

[0006] As a further aspect of the present invention: the inner cavity of the lower guide plate is provided with a concave section, and a gradually decreasing slope is formed from left to right. Through the slope setting, the water drained from the basket body automatically flows into the water receiving box under the action of gravity, which can be conveniently processed.

[0007] As a further aspect of the present invention: a movable plate is rotatably connected to the bottom of the side plate, and the left side of the movable plate abuts against the left side of the water receiving box. The movable plate covers the water receiving box. When it needs to be removed, first pull out the basket body, and then rotate the movable plate to expose the water receiving box for cleaning.

[0008] As a further aspect of the present invention: both sides of the inner cavity of the water receiving box are fixedly connected to side baffles that gradually slope downward from the sides to the middle, and the inner cavity of the water receiving box is fixedly connected to a baffle plate. By setting the baffle plate and the side baffles, water can be prevented from splashing out when the water receiving box moves left and right.

[0009] Compared with the prior art, the present invention has the following advantages: Highly Effective Mold Prevention and Active Drying: Through an innovative design featuring elastic airbags and air nozzles, a forced ventilation process is simultaneously initiated when the user closes the pull-out basket. After the elastic airbags are compressed, the internal air is directed and concentrated through the air nozzles onto the pull-out basket and its draining area. This airflow quickly removes residual moisture from the tableware surface, significantly accelerating the drying process of the drain basket and its contents. This fundamentally disrupts the humid environment necessary for microbial growth, achieving a qualitative shift from passive draining to active drying, effectively ensuring the hygiene of the tableware and the health of the storage environment.

[0010] Reliable closing lock and accidental pop-out protection: This invention cleverly utilizes the interaction between the push rod and the piston rod to achieve automatic mechanical locking after the pull-out basket is closed. When the pull-out basket is closed to the end of its stroke, the moving end of the piston rod automatically pops out and engages with the locking groove on the push rod, forming a secure mechanical interlock. This structure can reliably resist the rebound force generated when the elastic airbag is deployed, as well as external forces caused by cabinet vibration or minor collisions, completely avoiding the safety hazards of the pull-out basket sliding out on its own or accidentally popping out, thus improving the product's stability and safety.

[0011] Smooth, automated drainage and centralized collection: The lower guide plate is specially designed with a concave, gradually sloping structure from left to right. This design ensures that every drop of water dripping from the pull-out basket can automatically and smoothly flow along the preset sloping path under its own gravity and collect in the water collection box. This process requires no electricity or manual intervention, achieving automated and intelligent drainage, effectively preventing water accumulation and keeping the bottom of the cabinet dry for a long time.

[0012] Convenient water tray placement and splash protection: The water tray is slidably connected to the slide bar on the side of the lower guide plate via its protruding ends on both sides, allowing users to easily pull it out or push it in along the slide rail, making cleaning and maintenance extremely convenient. Meanwhile, the side baffles and splash guards added inside the water tray form multiple splash-proof barriers. Whether during the pulling-out basket process or when moving the water tray, these baffles effectively suppress the shaking and splashing of water inside the tray, ensuring the cleanliness of the cabinet interior and surrounding area.

[0013] User-friendly operation and structural linkage: The entire mechanism's operating logic is highly ergonomic. When closing the pull-out basket, the locking action is completed automatically, imperceptibly to the user. To open it, simply pull the handle while simultaneously using your thumb or forefinger to press the inner latch plate; the piston rod can then be remotely released via the pull cord – a smooth and seamless action. Furthermore, the movable plate design ensures a clean appearance and prevents foreign objects from falling into the water collection box, while its rotatable nature provides the necessary operating space for removing and placing the water collection box, demonstrating thoughtful attention to detail.

[0014] Energy saving, environmental protection, and structural reliability: All functions of this device rely on mechanical actions during use, requiring no additional power supply, thus saving energy and protecting the environment. Furthermore, there is no risk of circuit failure or short circuits that may occur in humid environments. The entire system has a simple structure, mainly composed of mechanical components, ensuring durability, long lifespan, and low maintenance costs. Attached Figure Description

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] Please see Figure 1-4 This invention provides a technical solution: an intelligent kitchen cabinet automatic drainage pull-out basket, including a pull-out basket body 3 and a side plate 1 fixed to the side of the pull-out basket body 3. A lower guide plate 4 is fixedly connected to the lower part of the pull-out basket body 3. An elastic airbag 8 is fixedly connected to the left side of the lower guide plate 4. A one-way air inlet 10 is opened on the surface of the elastic airbag 8. An air nozzle 11 facing the drain basket of the pull-out basket body 3 is opened on the right side of the elastic airbag 8. A top rod 9 is fixedly connected to the left side of the elastic airbag 8 through a rigid plate. A piston rod 14 is fixedly connected to the bottom of the pull-out basket body 3. A snap-fit ​​groove 13 is opened on the surface of the top rod 9 to engage with the moving end of the piston rod 14. A handle 15 is fixedly connected to the side of the side plate 1. A buckle plate 17 is slidably connected to the inner cavity of the handle 15. One side of the buckle plate 17 is connected to the piston rod 14 through a pull rope 16. The moving end of 4 is fixedly connected. When the pull-out basket body 3 is closed during use, the side plate 1 is pushed inward, and then the top rod 9 is pressed into the cabinet, compressing the elastic airbag 8. The gas in the elastic airbag 8 is blown out from the air nozzle 11 towards the pull-out basket body 3 to form airflow, preventing internal mold growth. The airflow can also accelerate the removal of water on the lower guide plate 4. After the top rod 9 moves to its limit, the moving end of the piston rod 14 extends and engages in the engagement groove 13, limiting the top rod 9 and compressing the elastic airbag 8 to prevent it from expanding and pushing the pull-out basket body 3 out of the cabinet. Then, when the pull-out basket body 3 is pulled out, the buckle plate 17 is pulled, the pull rope 16 is pulled, and the moving end of the piston rod 14 is retracted. At this time, the top rod 9 loses its limit and the elastic airbag 8 returns to its original position.

[0019] A water receiving box 5 is slidably connected to the bottom of the lower guide plate 4. The water receiving box 5 has protruding ends 6 on both sides. A sliding rod 7 that is slidably connected to the protruding ends 6 is fixedly connected to the side of the lower guide plate 4. The water flowing from the lower guide plate 4 is stored in the water receiving box 5, and the water receiving box can be easily removed for processing.

[0020] The lower guide plate 4 has a concave section inside, and forms a gradually decreasing slope from left to right. Through the slope, the water drained from the basket body 3 automatically flows into the water receiving box 5 under the action of gravity, which can be easily treated.

[0021] A movable plate 2 is rotatably connected to the bottom of the side panel 1. The left side of the movable plate 2 abuts against the left side of the water receiving box 5. The movable plate 2 covers the water receiving box 5. When it needs to be removed, first pull out the basket body 3, and then rotate the movable plate 2 to expose the water receiving box 5 for cleaning.

[0022] Both sides of the inner cavity of the water receiving box 5 are fixedly connected to side baffles 18 that gradually slope downward from the sides to the middle. The inner cavity of the water receiving box 5 is also fixedly connected to a baffle plate 19. The baffle plate 19 and the side baffles 18 can prevent water from splashing out when the water receiving box 5 moves left and right.

[0023] In use, the first stage of this invention involves closing the pull-out basket and activating the function. When the user needs to close the cabinet, they push the side panel 1 fixed to the side of the pull-out basket body 3 by hand, driving the entire pull-out basket into the cabinet. During this process, the top rod 9 fixed to the left side of the lower guide plate 4 below the pull-out basket body 3 will contact the inner wall of the cabinet before the pull-out basket body. As the pushing force continues, the top rod 9 is blocked by the inner wall of the cabinet and generates relative displacement, thereby squeezing the elastic airbag 8 fixed to it. Due to the one-way air inlet 10 design of the elastic airbag 8, the internal air cannot flow back from here. Therefore, when the volume is reduced by pressure, the internal air is forced to be ejected at high speed from the only outlet - the air nozzle 11. This airflow is directed at the draining area of ​​the pull-out basket body 3, performing the initial blowing and drying task. At the same time, the airflow will also sweep across the inclined surface of the lower guide plate 4, accelerating the flow and evaporation of the small water droplets on its surface towards the water collection box 5.

[0024] Phase Two: Mechanical Locking and Position Holding When the push rod 9 is pushed to its maximum travel position, i.e., when the elastic airbag 8 is compressed to its maximum extent, the moving end of the piston rod 14 installed at the bottom of the pull-out basket body 3 automatically extends under the action of an internal spring or mechanism, precisely engaging with the pre-set locking groove 13 on the surface of the push rod 9. This "locking" action constitutes a robust mechanical lock, effectively limiting the reverse movement of the push rod 9 under the rebound force of the elastic airbag 8. Therefore, although the elastic airbag 8 always attempts to expand and return to its original position, its force is completely offset by the interlocking structure of the piston rod 14 and the locking groove 13, thereby ensuring that the entire pull-out basket can stably remain inside the cabinet in the closed state and will not automatically retract.

[0025] Phase 3: Unlocking the basket and resetting the mechanism When the user needs to remove the tableware, they first grasp the handle 15, then use their fingers to slide the latch 17 connected to the inner cavity of the handle. The latch 17, through the pull cord 16 connected to it, can pull the moving end of the piston rod 14 with a soft steel wire rope or other high-strength cable, causing it to overcome resistance and retract from the locking groove 13. Once the lock is released, the push rod 9 immediately loses its restraint. At this time, the compressed elastic airbag 8 quickly expands using the elastic restoring force of its own material, pushing the push rod 9 outward a short distance. This initial action releases the internal restraint on the pull basket, allowing the user to easily pull the pull basket body 3 completely out of the cabinet.

[0026] Auxiliary workflow for drainage and water connection: During the entire push-pull process, water droplets dripping from the tableware fall onto the lower guide plate 4. Thanks to the gradually rising slope design of the lower guide plate 4's inner cavity from right to left, the water droplets automatically flow to the lowest-positioned water collection box 5 under gravity and are stored there. When the water collection box 5 needs cleaning, the user first pulls out the basket body 3, then rotates the movable plate 2 so that it no longer obstructs the left side of the water collection box 5. Then, the user can grasp the front of the water collection box 5 and smoothly pull it out along the slide bar 7. The side baffle 18 and water baffle 19 inside the water collection box 5 effectively prevent water from spilling during movement. After cleaning, simply push the water collection box 5 back in and rotate the movable plate 2 to restore its original position.
