Description

Technical Field

[0001] This utility model relates to the field of undermount sink technology, and in particular to a stainless steel undermount sink. Background Technology

[0002] Undermount sinks are commonly used drainage fixtures in kitchens and bathrooms. However, traditional stainless steel undermount sinks have several problems during use:

[0003] Firstly, the drainage system is poorly designed and does not differentiate between normal drainage and overflow. When the drainage pipes become blocked, water can easily accumulate in the basin, or even cause sewage to backflow, affecting the user experience and posing a hygiene hazard.

[0004] Secondly, the filtration structure is simple, and the normal drainage and overflow water share the same filtration path. The large amount of impurities carried by the overflow water can easily aggravate the clogging of the filtration device, thereby affecting the overall drainage efficiency.

[0005] Third, maintenance and repair are inconvenient. The internal structure mostly uses fixed connection methods. If it is necessary to check for blockages or repair parts, multiple components need to be disassembled with the help of tools, which is time-consuming and labor-intensive. Utility Model Content

[0006] The purpose of this invention is to provide a stainless steel undermount basin, which solves the above-mentioned problems by using this device.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a stainless steel undermount basin, including an undermount basin body, a drain pipe and a movable plate. The drain pipe is provided at the bottom of the undermount basin body, and a filter plate is installed at the top inside the drain pipe. The movable plate is installed inside the undermount basin body, and a support component is provided at the bottom of the movable plate. An overflow component is provided at the middle position of one end of the undermount basin body.

[0008] Preferably, the inner bottom wall of the undermount basin body is designed to be inclined, with the inner bottom wall of the undermount basin body inclined downward toward the drain pipe.

[0009] Preferably, the support assembly includes a support block disposed above the highest part of the inclined inner bottom wall of the undermount basin body. The support block is fixed to the inner side wall of the undermount basin body and located at the bottom of the movable plate. A rubber sound-absorbing base plate is fixed to the bottom wall of the movable plate. A positioning block is provided at one end of the bent part of the movable plate and is fixed to the inner bottom wall of the undermount basin body.

[0010] Preferably, the overflow component includes an overflow port opened on the side wall of the undermount basin body, the overflow port being located above the support block, a water guide pipe being provided at one end of the undermount basin body, one end of the water guide pipe being connected to the overflow port, a drain outlet being opened on the inclined end face of the inner bottom wall of the undermount basin body, and the other end of the water guide pipe being connected to the drain outlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a stainless steel undermount basin with an inclined movable plate and a filter plate with a zoned flow design, which separates normal drainage from overflow. During normal drainage, the movable plate guides the water flow through part a of the filter plate for rapid filtration before discharge; when the inside is blocked and water accumulates, the overflow component is activated, and the water is filtered through part b and discharged into the drain pipe. This dual-path system ensures smooth drainage and avoids water accumulation.

[0013] 2. The stainless steel undermount basin provided by this utility model has a movable plate supported only by positioning blocks and support blocks. During maintenance, no tools are required. The internal space of the undermount basin can be fully exposed by direct disassembly, which makes it easy for staff to quickly check blockages, clean impurities or repair parts, and greatly improves maintenance efficiency.

[0014] 3. The stainless steel undermount basin provided by this utility model has filter plates a and b that operate independently. They not only intercept debris in the normal drainage, but also perform secondary filtration on the overflow water to prevent overflow impurities from mixing into the normal drainage path and causing cross-blockage. At the same time, the overflow component can prevent water accumulation in the basin due to blockage of filter plate a, thus enhancing the safety of use.

[0015] 4. The stainless steel undermount basin provided by this utility model has a positioning block that accurately divides the filter plate area and fixes the front end of the movable plate, and a support block that distributes the load and stabilizes the rear end, ensuring that the tilt angle of the movable plate is stable, so that the water flow is guided efficiently and stably, and the service life of the equipment is extended.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1 to 4 As shown, the present invention provides a stainless steel undermount basin, including an undermount basin body 1, a drain pipe 2, and a movable plate 3. The drain pipe 2 is provided at the bottom of the undermount basin body 1, and a filter plate 21 is installed at the top inside the drain pipe 2. The movable plate 3 is installed inside the undermount basin body 1, and a support component is provided at the bottom of the movable plate 3. An overflow component is provided at the middle position of one end of the undermount basin body 1.

[0024] The inner bottom wall of the undermount basin body 1 is designed with an incline, and the inner bottom wall of the undermount basin body 1 slopes downward toward the drain pipe 2.

[0025] The support assembly includes a support block 33 located above the highest part of the inclined inner bottom wall of the undermount basin body 1. The support block 33 is fixed to the inner side wall of the undermount basin body 1 and located at the bottom of the movable plate 3. A rubber sound-absorbing base plate 31 is fixed to the bottom wall of the movable plate 3. A positioning block 32 is provided at one end of the bent part of the movable plate 3 and is fixed to the inner bottom wall of the undermount basin body 1.

[0026] The overflow assembly includes an overflow port 4 opened on the side wall of the undermount basin body 1. The overflow port 4 is located above the support block 33. A water guide pipe 41 is provided at one end of the undermount basin body 1. One end of the water guide pipe 41 is connected to the overflow port 4. A drain port 42 is opened on the inclined end face of the bottom wall of the undermount basin body 1. The other end of the water guide pipe 41 is connected to the drain port 42.

[0027] Specifically,

[0028] First, the layout of the positioning block 32 and the filter plate 21;

[0029] Positioning block 32: It is placed horizontally at the top center of the filter plate 21, dividing the filter plate 21 into two parts, a and b.

[0030] Part A: Responsible for filtering and guiding the water flow through the guide plate 3, which is the normal drainage path.

[0031] Part b: Responsible for filtering and guiding overflowing water flow, serving as an emergency drainage path.

[0032] Function of filter plate 21: to filter water from different sources in stages to prevent debris from clogging the drain pipe 2.

[0033] Secondly, the installation and support of movable plate 3;

[0034] Installation steps: Place the movable plate 3 inside the undermount basin body 1, ensuring that the front end of its bent portion is pressed against the positioning block 32. Place the rear end of the movable plate 3 on top of the support block 33, securing it by "front end pressing against + rear end support".

[0035] Functional advantages: The inclined movable plate 3 directs water flow to the drain pipe 2, using gravity to accelerate drainage. With no bolts or complex fixing structures, the movable plate 3 can be directly removed to expose the internal space during maintenance, facilitating upkeep.

[0036] Furthermore,

[0037] First, the normal drainage process:

[0038] Water flows into the undermount basin body 1 and falls onto the top of the movable plate 3. The inclined movable plate 3 directs the water flow towards the drain pipe 2. The water flows through part a of the filter plate 21, where impurities are intercepted, and the clean water flows into the drain pipe 2 and is discharged.

[0039] Secondly, the overflow drainage process is suitable for scenarios with blockages:

[0040] When the undermount basin body 1 becomes clogged, the water level rises to the overflow port 4. The overflowing water flows through the overflow port 4 into the water guide pipe 41, and then through the drain port 42 into section b of the filter plate 21. After the overflowing water is filtered through section b, the clean water flows into the drain pipe 2, preventing water accumulation inside the main body.

[0041] The movable plate 3 is supported only by the positioning block 32 and the support block 33, and can be removed directly without tools. After removing the movable plate 3, the interior of the undermount basin body 1 is unobstructed, making it easy for staff to check for blockages, clean impurities, or repair parts. Sections a and b have independent drainage channels to prevent overflow impurities from mixing into the normal drainage path and reduce the risk of cross-blockage.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] 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.
