Description

Technical Field

[0001] This invention relates to the field of kitchen furniture technology, specifically a kitchen preparation island for multiple application scenarios. Background Technology

[0002] In patent application CN104776477A, ​​a main cabinet is included, on which a stove is mounted. The main cabinet contains a range hood with an exhaust vent connecting to the outside. The outer casing of the range hood's smoke inlet channel is located on the inner side of the stovetop, and the smoke inlet mesh of the range hood is located on the side of the smoke inlet channel casing facing the stovetop. The advantages are: placing the range hood within the main cabinet of the island countertop reduces noise during operation, and ensures that fumes are drawn into the smoke inlet channel before they rise, reducing the spread of fumes towards the cook. It also eliminates the possibility of the range hood falling onto the stovetop. Preferably, a silencer is installed outside the range hood to further reduce noise during operation.

[0003] In most existing technologies, including the aforementioned patents, the following technical problems are common: First, although the extension panels or pull-out countertops of existing islands can expand the operating area, after the extension panels are extended, their point of gravity is far from the island body, generating a large overturning moment, which reduces the overall stability of the island. Furthermore, as the extension distance increases, the moment gradually increases, requiring operators to overcome increasing resistance to fully extend the extension panels, making pushing and pulling laborious. Moreover, long-term use can easily lead to wear or deformation of the slide rails, affecting the lifespan of the island and the user experience. Second, existing islands have a relatively limited function, typically used only as a food preparation work surface, and cannot be used for multiple tasks simultaneously. While islands offer flexible functionality within their footprint, they often require additional dining tables when needed, consuming extra kitchen or dining space. When the extension panel is not in use, it has no other purpose after retraction, resulting in low space utilization and failing to meet the needs of modern families for multifunctional furniture. Furthermore, existing island extension panels typically rely on fixed counterweights or the island's own weight to balance the overturning moment, making it impossible to adjust according to the actual load on the extension panel. When many items are placed on the extension panel, the existing balancing mechanism struggles to adapt to load changes, potentially causing the island to tilt forward or tip over, posing a safety hazard. Alternatively, additional fixed counterweights may be required, making the island bulky and difficult to move.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The problem this invention aims to solve is to provide a food preparation island that is easy to push and pull, multi-functional, and has an adjustable weight, addressing the issues of existing kitchen islands being difficult to push and pull, having limited functionality, and being unable to adjust the weight according to the load.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a kitchen preparation island for multiple scenarios, including an island body, multiple drawers installed on one side of the island body, a sink on the top of the island body, a lifting socket installed on the top of the island body, the lifting socket being embedded in the countertop of the island body, a panel on the top of the island body, the bottom of the panel being slidably connected to two sliding holes on the top of the island body via two sliders, and two counterweight grooves on one side of the island body, with a balancing mechanism installed in the counterweight grooves; The balancing mechanism includes a cable assembly and a stabilizing assembly. The cable assembly includes a pull ring and a steel wire rope. The top of the pull ring is welded to the bottom of the slider. The top of the steel wire rope is movably connected to the pull ring through a ring. The bottom of the steel wire rope is fixedly connected to the counterweight assembly through a locking hook. The stabilizing component includes a cam, the upper part of which is rotatably connected to both sides of the counterweight groove via a rotating shaft. The wire rope is attached to the middle of the side of the cam. Gears are fixedly sleeved at both ends of the rotating shaft. A rack is meshed with the top of the gear. The two racks are slidably connected to the counterweight groove respectively. The bottom sides of the slider are slidably connected to the two racks respectively.

[0007] Preferably, the counterweight assembly includes a counterweight block and four threaded rods. The top ends of the threaded rods pass through holes at the four corners of the counterweight block, and the bottom ends of the threaded rods are provided with limiting plates larger than the diameter of the holes. Nuts are threadedly connected to the top ends of the threaded rods.

[0008] Preferably, a connecting hook is fixedly connected to the top of the counterweight, the locking hook and the connecting hook are detachably connected, and a groove is provided in the middle of the bottom of the counterweight.

[0009] Preferably, a groove is provided on one side of the rack, and a locking block is fixedly connected to both sides of the slider. The two locking blocks are slidably connected to the two grooves respectively. When the panel moves outward, the slider drives the locking blocks to make the rack move synchronously.

[0010] Preferably, the bottom of the panel is provided with a positioning mechanism, which includes a positioning hole on the side of the slider, a positioning pin slidably installed in the island body, and a spring sleeved on the positioning pin. The positioning pin is inserted into the positioning hole to lock the panel in the extended position or the retracted position.

[0011] Preferably, fixing bars are fixedly connected to the upper part of both sides of the counterweight groove, and the two fixing bars restrict the highest point of the counterweight block to move upward.

[0012] Preferably, the lower part of the cam is fixedly connected to two limit posts on both sides of the middle section, and the two limit posts are slidably connected to the arc-shaped grooves on both sides of the counterweight groove.

[0013] Preferably, the arc of the motion trajectory of the limiting post when it rotates around the rotating shaft is consistent with the arc of the arc groove.

[0014] Preferably, a limiting strip is fixedly connected to one side of the rack, and the limiting strip is slidably connected to a sliding groove on the corresponding side of the counterweight groove that is longer than the limiting strip.

[0015] Preferably, a door panel is installed on the front of the island platform body, and the door panel is hinged to the island platform body to enclose the counterweight slot and internal mechanism.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By setting a balancing mechanism, the present invention realizes the automatic balance of torque during the extension of the panel, so that only a small force is needed to push the panel and the force is even throughout the operation. At the same time, the counterweight is designed to be detachable, which can be flexibly increased or decreased according to the load in different scenarios, and always maintains a light operating experience. By setting a horizontally sliding panel on the top of the island, the island can realize the flexible switching of three functions of daily storage, food preparation and dining in the same area, which significantly improves the utilization rate of kitchen space. When the panel moves outward, the slider pulls the steel wire rope through the pull ring. The steel wire rope drives the counterweight to move upward to generate a balancing torque. At the same time, after the slider moves a certain distance, it drives the rack to move through the locking block. The rack drives the gear and cam to rotate. The profile curve of the cam makes the tension arm of the steel wire rope gradually increase. The balancing torque generated by the counterweight matches the overturning torque generated by the extension of the panel in real time. This effectively solves the technical problems of traditional telescopic tabletops being light in the front and heavy in the back, difficult to push and pull, and easy to damage the slide rail due to torque changes during the extension process. It significantly extends the service life of the sliding mechanism and the island, and improves the comfort of use. (2) Four threaded rods and nuts are provided in the counterweight assembly. The counterweight blocks are detachably fixed by the threaded rods and nuts. When more items are placed on the panel, the total weight increases. The operator only needs to open the door panel on the front of the island body, unscrew the nuts, increase the number of counterweight blocks or replace them with heavier counterweight blocks according to the actual situation, and then tighten the nuts to fix them. By flexibly adjusting the total weight of the counterweight assembly, the balancing mechanism can adapt to different usage scenarios and panel loads, and always maintain a light operating experience when the panel extends and retracts. At the same time, a connecting hook is provided on the top of the counterweight block. The locking hook and the connecting hook can be detachably connected, which facilitates quick replacement of the counterweight block and makes the operation simple and quick. (3) By setting a horizontally sliding and extending panel on the top of the island body, and integrating a sink, lifting socket and drawer on the island body, the panel can be used as a daily storage table when it is retracted, and can be exposed on the island tabletop for food preparation when it is partially extended. When it is fully extended, it can form a suspended platform with a large space at the bottom for use as a dining table. This allows the island to achieve flexible switching of three functions within the same floor area, avoiding the waste of space by setting up multiple independent furniture to meet different needs, significantly improving the utilization rate of kitchen space. At the same time, the bottom space after the panel is extended makes it easy to place your legs when eating, improving the comfort of use. Attached Figure Description

[0021] like Figures 1 to 13 As shown, the present invention provides a kitchen preparation island for multiple scenarios, including an island body 1. Multiple drawers 102 are installed on one side of the island body 1 for storing kitchen utensils. A sink 103 is provided on the top of the island body 1 for easy washing of food. A lift-up socket 104 is installed on the top of the island body 1, embedded in the countertop of the island body 1. It can be raised when needed and stored in the countertop when not in use, keeping the countertop tidy. A panel 2 is provided on the top of the island body 1. The bottom of the panel 2 is slidably connected to two sliding holes on the top of the island body 1 via two sliders 201. The panel 2 can slide horizontally along the top of the island body 1 to extend or retract, thereby expanding the food preparation work surface. Two counterweight grooves are provided on one side of the island body 1, and a balancing mechanism is provided in the counterweight grooves to balance the overturning torque generated when the panel 2 extends. The balancing mechanism includes a cable assembly and a stabilizing assembly. The cable assembly includes a pull ring 3 and a steel wire rope 301. The top of the pull ring 3 is welded to the bottom of the slider 201. When the panel 2 slides outward, the slider 201 drives the pull ring 3 to move synchronously. The top of the steel wire rope 301 is movably connected to the pull ring 3 through a ring. The bottom of the steel wire rope 301 is fixedly connected to the counterweight assembly through a locking hook 302. When the pull ring 3 moves outward, the steel wire rope 301 is pulled, thereby driving the counterweight assembly to move. The stabilizing component includes a cam 4. The upper part of the cam 4 is rotatably connected to both sides of the counterweight groove via a rotating shaft 402. The cam 4 can swing around the rotating shaft 402. The wire rope 301 is in contact with the middle of the side of the cam 4. When the wire rope 301 is pulled, the two sides of the cam 4 provide lateral limit to the wire rope 301. Gears 403 are fixedly sleeved at both ends of the rotating shaft 402. The gears 403 rotate synchronously with the rotating shaft 402. The top of the gears 403 is meshed with a rack 404. The two racks 404 are slidably connected to the counterweight groove respectively. The racks 404 can move horizontally along the counterweight groove. The bottom sides of the slider 201 are slidably connected to the two racks 404 respectively. When the panel 2 moves outward a certain distance, the slider 201 contacts the racks 404 and drives the racks 404 to move synchronously.

[0022] In one embodiment of the present invention, the counterweight assembly includes a counterweight block 303 and four threaded rods 305. The top ends of the threaded rods 305 pass through holes at the four corners of the counterweight block 303. The bottom end of the threaded rod 305 is provided with a limiting plate larger than the diameter of the hole to prevent the counterweight block 303 from coming off the bottom end of the threaded rod 305. The top end of the threaded rod 305 is threadedly connected to a nut 306. By tightening the nut 306, the counterweight block 303 can be fixed on the threaded rod 305. By replacing the counterweight block 303 with different weights or increasing or decreasing the number of counterweight blocks 303, the total weight of the counterweight assembly can be adjusted to accommodate panels 2 of different weights.

[0023] As one embodiment of the present invention, a connecting hook 304 is fixedly connected to the top of the counterweight 303, and the locking hook 302 is detachably connected to the connecting hook 304 to facilitate the replacement of the counterweight 303. A groove is provided in the middle of the bottom of the counterweight 303 to avoid the structure below.

[0024] In one embodiment of the present invention, a groove 4043 is provided on one side of the rack 404, and a locking block 4042 is fixedly connected to both sides of the slider 201. The two locking blocks 4042 are slidably connected to the two grooves 4043 respectively. When the panel 2 moves outward, the slider 201 moves independently for a certain distance first, and the locking block 4042 slides in the groove 4043. When the locking block 4042 slides to the end of the groove 4043, the slider 201 starts to drive the rack 404 to move outward synchronously.

[0025] In one embodiment of the present invention, a positioning mechanism is provided at the bottom of the panel 2. The positioning mechanism includes a positioning hole 202 opened on the side of the slider 201, a positioning pin 203 slidably installed in the island body 1, and a spring 204 sleeved on the positioning pin 203. The positioning pin 203 is inserted into the positioning hole 202 to lock the panel 2 in the extended position. When the panel 2 is moved into place, the positioning pin 203 is inserted into the positioning hole 202 under the elastic force of the spring 204 to achieve positioning and locking. When it is necessary to move the panel 2, the panel 2 is pushed with a little force and the positioning pin 203 retracts to release the lock.

[0026] As one embodiment of the present invention, fixing strips 5 are fixedly connected to the upper part of both sides of the counterweight groove. The two fixing strips 5 limit the highest point of the counterweight block 303 to move upward, so as to prevent the counterweight block 303 from exceeding the design range during the movement.

[0027] In one embodiment of the present invention, the lower middle part of the cam 4 is fixedly connected to two limit posts 401 on both sides. The two limit posts 401 are slidably connected to the arc grooves 6 on both sides of the counterweight groove. When the limit posts 401 rotate around the rotating shaft 402, the arc of the motion trajectory is consistent with the arc of the arc groove 6. The arc groove 6 plays a guiding and limiting role for the limit posts 401, ensuring that the cam 4 swings along the predetermined trajectory.

[0028] In one embodiment of the present invention, a limiting strip 4041 is fixedly connected to one side of the rack 404. The limiting strip 4041 is slidably connected to a sliding groove on the corresponding side of the counterweight groove that is longer than the limiting strip 4041. The limiting strip 4041 guides and limits the movement of the rack 404, ensuring that the rack 404 moves smoothly.

[0029] As one embodiment of the present invention, a door panel 101 is installed on the front of the island body 1. The door panel 101 is hinged to the island body 1 and is used to close the counterweight slot and internal mechanism, keep the island appearance clean, and facilitate the addition or removal of counterweight blocks 303 by opening the door panel 101.

[0030] Working principle and usage process of the present invention: Initial state: Panel 2 is in the retracted state, located at the top of the island body 1, slider 201 is located at the inner end of the sliding hole, at this time, counterweight 303 is located at the bottom of the counterweight groove under its own weight, wire rope 301 is in a slack state, cam 4 is in a naturally drooping position under the action of gravity, gear 403 and rack 404 are in the initial meshing state, at this time panel 2 can be used as a normal tabletop to place everyday items; When the water tank 103 and countertop inside the island platform 1 are needed for food preparation, the operator pushes the panel 2 outward. As the panel 2 moves outward, it causes the slider 201 to slide outward along the sliding hole. The slider 201 drives the pull ring 3 to move outward simultaneously. The pull ring 3 pulls the wire rope 301, and the wire rope 301 pulls the counterweight 303 upward through the locking hook 302. In the initial stage, the locking block 4042 at the bottom of the slider 201 slides in the groove 4043 of the rack 404. At this time, the slider 201 moves independently and has not yet driven the rack 404 to move. When the wire rope 301 is pulled, the wire rope 301 is in contact with the middle of the side of the cam 4. The wire rope 301 pulls the counterweight 303 upward through the locking hook 302. At this time, the extended panel 2 is not far away, and its weight is close to the weight of the counterweight 303. As panel 2 continues to move outward, the extension distance gradually increases. When the locking block 4042 at the bottom of slider 201 slides to the end of groove 4043, the locking block 4042 begins to push rack 404 to move outward synchronously. When rack 404 moves outward, it drives gear 403 meshing with it to rotate. Gear 403 drives cam 4 to rotate synchronously through shaft 402. When cam 4 rotates, the support position of its side on wire rope 301 changes, and the effective tension arm of wire rope 301 gradually increases, causing the tension of wire rope 301 on counterweight 303 to gradually increase. As the distance panel 2 moves outward increases, the rotation angle of cam 4 gradually increases, and the tension of wire rope 301 on counterweight 303 also gradually increases. Counterweight 303 continues to gradually lift upward. When counterweight 303 moves upward, the gravitational torque it generates gradually increases, balancing the overturning torque generated by the extension of panel 2. Due to the contour curvature of cam 4... The cable is specially designed so that the tension curve of the steel wire rope 301 matches the torque curve generated by the extension distance of the panel 2. Therefore, during the entire process of the panel 2 gradually moving out in the latter half, the balancing torque generated by the counterweight 303 is always basically equal to the overturning torque generated by the extension of the panel 2. The operator only needs to use a small force to push the panel 2 throughout the process, and the panel 2 is subjected to uniform force throughout the process, which will not cause impact or damage to the slider 201 and the island body 1. When the panel 2 is pushed to the final position, the positioning pin 203 is inserted into the positioning hole 202 of the slider 201 under the elastic force of the spring 204, locking the panel 2 in the extended position, forming a suspended platform with a large space at the bottom. By placing a few bar stools near the panel 2, the panel 2 can become a dining table, and the space at the bottom allows people to easily place their legs when sitting in the chair. The tabletop of the island body 1 is exposed, which can be used for food preparation. Weight adjustment of counterweight 303: When more items are placed on the island countertop, the total weight of panel 2 and the items above it will increase, and the original counterweight 303 may not be able to fully balance the overturning moment generated by the extension of panel 2. At this time, the operator can open the door panel 101 on the front of the island countertop body 1, use a tool to unscrew the nut 306, increase the number of counterweights 303 or replace them with heavier counterweights 303 as needed, and then tighten the nut 306 to fix it. By adding or removing counterweights 303, the total weight of the counterweight assembly can be flexibly adjusted to adapt to different usage scenarios and the load on panel 2; When panel 2 needs to be retracted, the operator pushes panel 2 inward with a little force. The positioning pin 203 moves inward to release the lock. Only a small amount of force is needed to move panel 2 inward. At this time, slider 201 drives pull ring 3 to move inward, the wire rope 301 loosens, and the counterweight 303 moves downward under its own weight. The wire rope 301 pulls slider 201 inward to assist panel 2 in retraction. At the same time, rack 404 moves inward, driving gear 403 to rotate in the opposite direction. Cam 4 swings in the opposite direction to reset, thus resetting panel 2.
