Description

Technical Field

[0001] This utility model relates to the technical field of drain baskets, and in particular to a telescopic drain basket for a water tank. Background Technology

[0002] In daily kitchen use, the sink is an essential facility for washing food and tableware. However, food scraps and debris generated during washing can easily clog the drain if they go directly down the drain, causing inconvenience for subsequent use and maintenance. Currently, there are some drain baskets on the market for filtering food scraps, but most have a fixed structure, limited capacity, and only filter holes at the bottom. This results in slow drainage and inconvenient storage, presenting certain limitations in use and storage.

[0003] In view of this, this utility model is developed by deeply conceiving and actively researching and improving the design of existing water tank residue drainage structures to address the many shortcomings and inconveniences caused by their imperfections. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a retractable drain basket for a sink that has a large capacity, fast drainage, and can effectively intercept garbage and is easy to store.

[0005] To achieve the above objectives, the solution of this utility model is: A retractable drain basket for a sink includes a support frame, multiple hollow filter side frames that taper from the outside in, and a filter bottom frame. The multiple filter side frames and the filter bottom frame are retractably connected together. The filter bottom frame is retractably connected to the innermost filter side frame. The outermost filter side frame is detachably mounted on the support frame and has a handle. Each filter side frame has multiple side filter holes on its peripheral wall. The bottom of the filter bottom frame has multiple bottom filter holes. The support frame is connected to a connector.

[0006] Furthermore, the two adjacent filter side frames and the innermost filter side frame and the filter bottom frame are respectively connected by limiting protrusions and limiting grooves to achieve expansion and contraction.

[0007] Furthermore, except for the outermost filter side frame, the other filter side frames and the filter bottom frame are respectively provided with the limiting protrusions around their outer perimeter. The adjacent outer filter side frames are provided with the limiting grooves corresponding to the limiting protrusions. The limiting protrusions of the filter bottom frame correspond to the limiting grooves provided on the innermost filter side frame.

[0008] Furthermore, the top of the outermost filter side frame has a retaining edge with an outer diameter larger than that of the support frame, which allows the filter side frame to be secured to the support frame.

[0009] Furthermore, each filter side frame is provided with multiple elongated filter holes around its perimeter, and the filter bottom frame is provided with multiple rows of elongated filter holes.

[0010] Furthermore, the connector can be any one of a suction cup, hook, hanging rope, or snap fastener.

[0011] Furthermore, a hanging hole is provided on each side of the support frame, and the connector is a handle. Each end of the handle is provided with a buckle that corresponds to and cooperates with the hanging hole. The support frame and the connector are detachably connected together by the cooperation of the buckle and the hanging hole.

[0012] Furthermore, a support point is provided at the bottom of the support frame.

[0013] Furthermore, the height of the filter side frame and the filter bottom frame is less than or equal to the height of the support frame.

[0014] Furthermore, the support frame, filter side frame, and filter bottom frame are all square structures, and all four corners are chamfered.

[0015] Compared to existing technologies, this utility model of a telescopic drain basket for water tanks differs from conventional drain baskets. Traditional drain baskets use a single-layer fixed structure, relying solely on bottom holes for drainage. This utility model, however, utilizes side filter holes on the side walls of multiple filter side frames to create a three-dimensional drainage channel. Existing products still require the extended state for storage; this solution, through its telescopic structure, compresses the overall volume to the size of a single filter side frame. When emptying residue, the outermost filter side frame faces downwards, and the bottom and side filter frames retract towards the outermost frame, simultaneously pushing out the residue, making residue removal very easy. Traditional products have a fixed capacity and cannot accommodate varying washing volumes; this utility model significantly increases capacity when extended, meeting the needs of cleaning large volumes of residue. With the above structure, this utility model increases the drain basket's capacity, significantly improves drainage efficiency through coordinated drainage from the side walls and bottom, and greatly reduces storage space due to the retractable structure. The detachable design of the filter structure and support frame facilitates separation and cleaning, and the tapered connection ensures smooth movement of each frame layer, preventing jamming due to dimensional deviations.

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] like Figures 1 to 5 As shown, this utility model discloses a kitchen telescopic drain basket, including a support frame 1, multiple hollow filter side frames 2 that gradually shrink from the outside to the inside, and a filter bottom frame 3. The multiple filter side frames 2 and the filter bottom frame 3 are telescopically connected together. The filter bottom frame 3 is telescopically connected to the innermost filter side frame 21. The outermost filter side frame 22 is detachably mounted on the support frame 1. The outermost filter side frame 22 is provided with a handle 23. Each filter side frame 2 has multiple side filter holes 24 on its peripheral wall. The bottom and all sides of the filter bottom frame 4 are provided with multiple bottom filter holes 31. The support frame 1 is connected to the connector 4.

[0023] The support frame 1 and connector 4 serve as a fixed base, suspended from the edge of the water tank. The multi-layered filter frames (side filter frames 2 and bottom filter frames 3) form a stepped volume space when unfolded. During cleaning, water flows through the side filter holes 24 and bottom filter holes to achieve three-dimensional drainage, while residue is intercepted by each layer of the frame. In the retracted state, all filter frames are completely nested, with the overall height comparable to a single-layer frame. The handle 23 facilitates the removal of the entire filter frame (side filter frames 2 and bottom filter frames 3) for residue cleaning. The connector 4 can be selected from suction cups or hooks depending on the type of water tank for quick installation.

[0024] Compared to existing technologies, traditional drain baskets use a single-layer fixed structure, relying solely on bottom holes for drainage. This invention, however, utilizes side filter holes 24 on the side walls of multi-layered filter side frames 2 to create a three-dimensional drainage channel. Existing products still require the product to be stored in an unfolded state; this invention, through a telescopic structure, can compress its overall volume to the size of a single filter side frame 2. Traditional products have a fixed capacity and cannot accommodate varying washing volumes; this invention, when unfolded, significantly increases its capacity, accommodating large amounts of residue.

[0025] Through the above technical solutions, this utility model increases the capacity of the drain basket, significantly improves drainage efficiency through coordinated drainage from the side walls and bottom, and greatly reduces the storage space due to the retractable structure. The detachable design of the filter structure and support frame facilitates separation and cleaning, and the tapered fitting ensures smooth movement of each frame layer, avoiding jamming caused by dimensional deviations.

[0026] In this embodiment, the two adjacent filter side frames 2 and the innermost filter side frame 2 and the filter bottom frame 3 are respectively connected by limiting protrusions 5 and limiting grooves 6 to achieve expansion and contraction.

[0027] When the drain basket needs to be unfolded, the limiting protrusion 5 slides downward along the limiting groove 6, causing each layer of filter side frame 2 to unfold sequentially, forming a multi-layered filtration space. When it needs to be folded up, the limiting protrusion 5 slides upward along the limiting groove, causing each layer of filter side frame 2 and filter bottom frame 3 to nest and shrink layer by layer. During this process, the length of the limiting groove 3 determines the maximum range of the extension and retraction stroke. This utility model achieves the extension and retraction of the multi-layered filtration structure through the mechanical cooperation between the limiting protrusion 5 and the limiting groove 6. Although there are foldable drain baskets in the prior art, their interlayer connections mostly rely on hinges or soft materials, resulting in low structural strength and easy deformation. This utility model, however, improves structural reliability while ensuring smooth extension and retraction through the rigid contact between the limiting protrusion and the limiting groove. The expansion and retraction structure increases the volume to meet the drainage needs of different ingredients or tableware; at the same time, the folded nested structure significantly reduces the space occupied, making it easy to store in the sink or cabinet.

[0028] like Figure 1 As shown, in a specific implementation of the above embodiment, except for the outermost filter side frame 22, the other filter side frames 2 and the filter bottom frame 3 are respectively provided with the limiting protrusions 5 on their outer periphery. The adjacent outer filter side frames 2 are provided with the limiting long grooves 6 corresponding to the limiting protrusions 5. The limiting protrusions 5 of the filter bottom frame 3 correspond to the limiting long grooves 6 provided on the innermost filter side frame 21.

[0029] There are various ways to connect the filter side frame 2 to the support frame 1. For ease of use, this embodiment has a retaining edge 25 at the top of the outermost filter side frame 2 with an outer diameter larger than that of the support frame 1. The retaining edge 25 secures the filter side frame 2 to the support frame 1. When cleaning or removing residue from the filter side frame 2 or the filter bottom frame 3, simply lift the outermost filter side frame 22 upwards using the handle 23 to separate it from the support frame 1. This is very convenient and allows for tool-free quick assembly and disassembly of the filter side frame 2 and the support frame 1, simplifying the operation while ensuring structural stability. The overlapping design of the retaining edge 25 effectively prevents the filter side frame 2 from falling off due to external force during use, and disassembly does not require disconnecting multiple connection points, significantly improving maintenance and cleaning efficiency.

[0030] In this embodiment, each filter side frame 2 has multiple elongated side filter holes 24 around its perimeter, and the bottom surface and perimeter of the filter bottom frame have multiple elongated bottom filter holes 25. The elongated side filter holes 24 on the perimeter of the filter side frame 2 increase the length of the holes, allowing water to drain quickly along the long axis of the holes, while reducing the probability of food residue accumulating at the edges of the holes. The multiple rows of elongated bottom filter holes 25 in the filter bottom frame 3 increase the density of the holes per unit area, forming a continuous drainage channel at the bottom, allowing water to be evenly dispersed along the long axis of the holes under gravity. The side filter holes 24 and bottom filter holes 25 of the filter side frame 2 and filter bottom frame 3 work together to accelerate lateral drainage in the vertical direction through the side filter holes 24 and form multi-path drainage in the horizontal direction through the bottom filter holes 25, thereby improving overall drainage efficiency.

[0031] There are multiple ways to connect the support frame 1 and the connector 4. The connector 4 can be any one of a suction cup, hook, hanging rope, or snap fastener. If the connector 4 is a suction cup, hook, or hanging rope, the suction cup adheres to a smooth surface after squeezing out the internal air, making the drain basket stably fixed to the inner wall of the sink. The hook is snapped onto the edge of the sink or a pre-set bracket through a bending structure, allowing the drain basket to hang above the sink. The hanging rope can be adjusted at different heights by adjusting the length of both ends and the position of the fixing point, adapting to diverse kitchen layouts. The snap fastener allows the drain basket to be disassembled from its fixed position and folded for storage through the quick separation of the male and female snap fasteners, reducing space occupation. The above connection methods can be freely switched according to the usage environment. For example, suction cup fixation can be selected in narrow spaces, and snap fastener connection can be selected when frequent movement is required.

[0032] like Figure 1 In the embodiment shown, the support frame 1 is provided with a hanging hole 11 on each side, and the connector 4 is a handle. Each end of the handle is provided with a buckle 41 that corresponds to and cooperates with the hanging hole 11. The support frame 1 and the connector 4 are detachably connected together by the cooperation of the buckle 41 and the hanging hole.

[0033] Preferably, the hanging hole 11 is provided with a shaft hole 12, the buckle 41 is provided with a rotating shaft 42 that corresponds to and cooperates with the shaft hole 12, and the bottom of the support frame 1 is also provided with a support point 13. The cooperation between the rotating shaft 42 and the shaft hole 12 allows the support frame 1 and the connector 1 to rotate at any angle, which can further reduce the storage volume when stored. The design of the support point 13 allows the support frame 1 to form a certain tilt when placed vertically, so as to prevent the filter side frame 2 and the filter bottom frame 3 from detaching from the support frame 1.

[0034] Preferably, the height of the filter side frame 2 and the filter bottom frame 4 is less than or equal to the height of the support frame 1, so that the filter side frame 2 and the filter bottom frame 4 can be retracted and stored in the support frame 1.

[0035] In this embodiment, the support frame 1, filter side frame 2, and filter bottom frame 3 are all square structures, and all four corners are chamfered to facilitate cleaning and prevent scratches.

[0036] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
