Description

Technical Field

[0001] This utility model relates to the field of household sink technology, and in particular to a cabinet sink structure with anti-overflow function. Background Technology

[0002] Household washbasins, used to hold large amounts of water for washing dishes and food, are primarily made of stainless steel. In addition, materials such as enamel iron and ceramics are also widely used in this field.

[0003] For the design of water tanks to prevent overflow, existing technologies have widely adopted related devices to prevent safety hazards and cleaning temperature problems caused by water overflow, and to prevent the water tank from falling off the support surface due to excessive liquid in the water tank.

[0004] In existing technology, to control overall costs, household sinks typically use overflow holes to prevent overflow. However, since the overflow hole remains open during daily use, wastewater generated during cleaning inevitably splashes into the cabinet, causing contamination and creating a damp environment that promotes bacterial growth.

[0005] In view of this, this study proposes a new cabinet sink structure that not only has the function of preventing overflow, but also solves the aesthetic problem of existing overflow hole design, while effectively avoiding dirt and mold caused by sewage. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model proposes a cabinet sink structure with an anti-overflow function. This structure combines aesthetics and practicality, effectively preventing sewage from splashing into the cabinet and solving the problems of traditional overflow hole designs affecting aesthetics and easily causing internal cabinet pollution and mold growth.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cabinet sink structure with anti-overflow function includes an inner liner and an outer shell. The inner liner is nested within the outer shell, and a filter hole is provided through the lower end of the inner liner. A connecting pipe is connected to the lower end of the outer shell. A compression spring is provided inside the outer shell. One axial end of the compression spring abuts against a positioning plate, and the other axial end of the compression spring abuts against a blocking plate. The positioning plate is movably connected to the outer shell. An overflow hole is provided through the inner liner for the blocking plate. The projection of the blocking plate on the vertical plane completely covers the projection of the overflow hole on the vertical plane. A sealing gasket is fixedly connected to the end of the blocking plate near the inner liner. When the compression spring is not affected by external force, the sealing gasket abuts against the outer end of the inner liner, and the sealing gasket and the inner liner are interference-fitted.

[0009] Preferably, the outer shell has a through-hole with an internal thread, and a positioning rod is screwed into the internal thread. One axial end of the positioning rod is fixedly connected to a positioning plate, and the other axial end of the positioning rod is fixedly connected to a driving block. The driving block is located on the outside of the outer shell.

[0010] Preferably, the positioning rod has a limiting hole with a polygonal vertical structure at one end near the blocking plate, and a limiting rod is inserted into the limiting hole and fixedly connected to the blocking plate.

[0011] Preferably, when the support plate abuts against the outer end of the inner liner, the height of the upper surface of the outer shell is less than the height of the upper surface of the inner liner, and the upper end of the outer shell is provided with a horizontal mounting hole with a central axis, into which a limit bolt is inserted.

[0012] Preferably, the inner side of the outer shell is provided with a plurality of support plates, which abut against the outer end of the inner liner.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention designs a structure that combines an inner liner and an outer shell. The height difference between the two allows the inner liner to function as a "medium-sized basin," ensuring both aesthetics and practicality. Furthermore, the device effectively prevents overflow of the inner liner through the coordinated use of an overflow hole, a blocking plate, and a compression spring. Compared to existing technologies, this device, under normal operating conditions, ensures predictable liquid flow, allowing wastewater to be directly discharged into the sewer through the connecting pipe, effectively avoiding pollution and mold growth caused by wastewater splashing.

Therefore, they should not be construed as limitations on this utility model.

[0024] Please see Figure 1 A cabinet sink structure with anti-overflow function is disclosed, which mainly consists of an inner liner 3 and an outer shell 1, with the inner liner 3 nested inside the outer shell 1. This structural design enhances the aesthetic value of the cabinet sink while ensuring its practicality.

[0025] It is worth noting that, such as Figure 1 As shown, the support surface is specially designed with a matching receiving groove for the inner tank 3, allowing the inner tank 3 to be perfectly embedded within it. This design makes the inner tank 3 similar to a common "recessed basin" in practical applications, ensuring both the ease of cleaning the support surface and maintaining the overall aesthetics. In addition, the embedded design of the inner tank 3 also enhances the stability and durability of the sink.

[0026] At the same time, such as Figure 1 , Figure 3 , Figure 5 As shown, a support rod is fixedly connected to the lower end of the support platform. The outer shell 1 is relatively fixed by the support rod and bolts. Inside the outer shell 1, a support plate 7 is provided for the inner liner 3. Figure 6As shown, the support plate 7 is abutted against the inner liner 3. This allows the outer shell 1 to assist in supporting the inner liner 3, thus solving the problem of fixing the "mid-mount basin" in existing devices, which poses a risk of the inner liner 3 falling off due to aging or damage to the support surface during actual use. This innovative double-support design significantly enhances the structural stability of the cabinet sink.

[0027] Specifically, in practical applications, the support platform can be made of wood, while the support rods can be made of timber. The two are firmly connected by pneumatic nails, which is not only cost-effective and easy to assemble, but also provides users with a large degree of customization. This material selection and assembly method is not only economical, but also allows users to customize according to their personal preferences.

[0028] Specifically, such as Figure 3 , Figure 5 The upper end of the outer casing 1 shown has a horizontal mounting hole 16 with a central axis, into which a limiting bolt 9 is inserted. By placing the limiting bolt 9 horizontally, the upper surface of the support platform is ensured to remain level, while preventing the limiting bolt 9 from protruding, thus maintaining the aesthetics of the support platform. This design ensures a clean appearance for the cabinet sink while guaranteeing safety during use.

[0029] Specifically, such as Figure 3 , Figure 6 As shown, the support plate 7 has an overall I-shaped structure. In practical applications, it can be fixed to the inside of the outer shell 1 by spot welding. This design utilizes the I-shaped structure of the support plate 7 to ensure that the support plate 7 has a large contact area with the outer shell 1 and the inner liner 3, thereby ensuring the stability of the inner liner 3 during use. This structural design not only improves the support effect but also enhances the overall durability.

[0030] In addition, such as Figure 2 , Figure 3 As shown, consistent with existing technology, a filter hole 5 is provided through the lower end of the inner tank 3. In practical applications, a filter element is further placed inside the filter hole 5. This design effectively filters impurities in the sink and prevents clogging. This filtration design ensures the cleanliness of the cabinet sink and enhances the user experience.

[0031] Correspondingly, a connecting pipe 6 is connected to the lower end of the outer casing 1. In practical applications, the lower end of the connecting pipe 6 can be connected to the indoor drain pipe. The connecting pipe 6 is responsible for draining the filtered water, ensuring that the sink remains clean and hygienic. This drainage design ensures the hygiene of the cabinet sink and avoids the accumulation of sewage.

[0032] In practical applications, users primarily interact with the inner tank 3 of this device, and the cleaning process is mainly completed within the inner tank 3. During cleaning, wastewater flows into the inner cavity of the outer shell 1 through the filter holes 5, and then drains into the sewer pipe through the connecting pipe 6. This cleaning process is simple and convenient, ensuring the cleanliness and hygiene of the kitchen sink.

[0033] It is important to emphasize that in practical applications, there is no rigid connection between the inner tank 3 and the outer shell 1. The outer shell 1 is secured to the support rod with bolts, allowing for easy disassembly. Therefore, after a period of use, users can disassemble the outer shell 1 themselves to clean its interior and prevent mold and odor buildup. This design makes the maintenance of the kitchen sink simple and easy.

[0034] Please see Figure 2 , Figure 3 , Figure 4 This device features an overflow hole 2 on the side of the inner tank 3. This hole ensures that the maximum water volume stored in the inner tank 3 does not exceed expectations, preventing the storage of expired liquid in the inner tank 3 due to forgetfulness or blockage of the filter hole 5, thus preventing liquid overflow and unnecessary cleaning. This overflow hole 2 design ensures the safe use of the cabinet sink and avoids potential water loss risks.

[0035] Compared with existing technologies, the overflow hole 2 of this device is not limited to the upper end of the inner tank 3, but can also be set at the side or lower end of the inner tank 3. This flexible design meets the needs of different users and provides more installation and usage options.

[0036] To ensure the normal water storage function of the inner tank 3, a compression spring 11 is installed inside the outer shell 1. One end of the compression spring 11 abuts against the positioning plate 17, and the other end is fixedly connected to the blocking plate 13. This flexible connection between the positioning plate 17 and the outer shell 1 ensures that the blocking plate 13 fully covers the overflow hole 2 in its vertical projection during sink operation, effectively preventing water flow and ensuring normal water storage in the inner tank 3. Only when the amount of water stored in the inner tank 3 exceeds the expected level, and the force exerted by the liquid on the blocking plate 13 exceeds the elastic force of the compression spring 11, will the blocking plate 13 disengage from the outer end of the inner tank 3, thus preventing overflow. This overflow-proof design ensures the safe operation of the cabinet sink and effectively avoids the risk of water damage.

[0037] It is important to note that the location of the overflow hole 2 in this device is primarily based on actual usage requirements. If the user has high requirements for the accuracy of the maximum water storage capacity, the overflow hole 2 should be located at the lower end of the inner tank 3. In this case, the weight of the liquid acts directly on the blocking plate 13, and the liquid gravity coincides with the elastic force of the compression spring 11. If the overflow hole 2 is located on the side of the inner tank 3, the weight of the liquid will not act entirely on the blocking plate 13, and the maximum water storage capacity in the inner tank 3 can be maintained within a certain range. This design considers the needs of different usage scenarios and provides a flexible water storage solution.

[0038] Furthermore, to ensure the sealing effect of the blocking plate 13, a sealing gasket 8 is fixedly connected to one end of the blocking plate 13 near the inner liner 3. When the compression spring 11 is not subjected to external force, the sealing gasket 8 is in close contact with the outer end of the inner liner 3, and the sealing gasket 8 and the inner liner 3 are in an interference fit. Thus, under normal circumstances, there is no gap between the sealing gasket 8 and the inner liner 3, effectively preventing water overflow. This sealing design ensures the leak-proof performance of the cabinet sink and improves the safety of use.

[0039] like Figure 4 , Figure 5 As shown, specifically, to precisely control the maximum water storage capacity in the inner tank 3, this device cleverly incorporates an internally threaded hole 15 on the outer shell 1, tailored to different depths and the position of the overflow hole 2, and achieves this through a screw-in positioning rod 10. One end of the positioning rod 10 is securely connected to the positioning plate 17, while the other end is connected to a drive block 4 located on the outside of the outer shell 1. Users can easily adjust the position of the positioning rod 10 by simply rotating the drive block 4, thereby changing the initial compression of the compression spring 11 and flexibly adapting to the usage needs of various sinks. This innovative adjustable design greatly enhances the water storage flexibility of the cabinet sink, enabling it to easily cope with more diverse usage scenarios.

[0040] To prevent the blocking plate 13 from failing to rotate synchronously with the positioning plate 17, which could cause the compression spring 11 to twist and malfunction, this device features a polygonal limiting hole 14 at the end of the positioning rod 10 near the blocking plate 13. A limiting rod 12 is inserted into the limiting hole 14 and fixedly connected to the blocking plate 13. This design ensures that the blocking plate 13 rotates synchronously with the positioning plate 17 during sink use. This synchronous rotation mechanism ensures stable operation of the cabinet sink and avoids malfunctions caused by component misalignment.

[0041] It must be pointed out that, such as Figure 2 , Figure 3As shown, the connecting pipe 6 of this device has a large inner diameter, significantly exceeding that of a household water faucet. Therefore, under normal operating conditions, wastewater generated by the user can flow very smoothly into the connecting pipe 6 after passing through the filter holes 5, without any contact with the inner wall of the outer casing. This ingenious design maintains the dryness of the inner cavity of the outer casing during operation, significantly reducing cleaning requirements and thus greatly alleviating the user's maintenance workload.

[0042] Furthermore, it is worth noting that the presence of the filter element plays a crucial role in the filter holes 5. Through its specific material and pore size, it effectively slows down the drainage rate, ensuring that the drainage rate does not exceed the maximum flow capacity of the connecting pipe 6 under normal operating conditions.

[0043] In the practical application of this utility model:

[0044] First, users can conveniently use household tap water for various cleaning tasks. During the cleaning process, the wastewater generated will flow directly into the connecting pipe 6 through the filter hole 5 and eventually be discharged into the sewer pipe;

[0045] Subsequently, if the user neglects to turn off the faucet during operation, and the filter hole 5 becomes clogged, the liquid cannot smoothly enter the connecting pipe 6. At this time, the liquid in the inner tank 3 will continue to accumulate, and the pressure on the sealing gasket 8 will gradually increase.

[0046] Then, as the liquid continues to accumulate inside the inner liner 3, the pressure exerted by the liquid on the sealing gasket 8 continues to increase until the pressure exceeds the elastic force exerted by the compression spring 11 on the blocking plate 13. At this point, the contact state between the sealing gasket 8 and the outer wall of the inner liner 3 is broken, and the liquid accumulated inside the inner liner 3 flows into the inner cavity of the outer shell 1 through the overflow hole 2, and then flows into the connecting pipe 6 and is discharged into the drain pipe.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
