Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory table technology, specifically to a bidirectional flow-guided anti-slip drain groove disc-shaped ceramic tabletop. Background Technology
[0002] Laboratory sinks are an indispensable piece of equipment in laboratories, used for cleaning, disinfection, and experimental operations. They are usually composed of a sink and a work surface.
[0003] Existing laboratory sinks typically only have basic cleaning functions. After washing experimental equipment, water droplets easily splash onto the surface, causing water accumulation and preventing the surface from remaining dry and clean. This can lead to moisture contamination and even damage to experimental items. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a bidirectional flow-guiding, non-slip, drip-draining ceramic tabletop that overcomes the deficiencies of existing technologies. Its reasonable design allows water to flow smoothly along the strip-shaped drip groove into the water tank mounting hole, ensuring the dryness and cleanliness of the experimental tabletop.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A bidirectional, anti-slip, dish-shaped ceramic countertop includes a ceramic body. The upper surface of the ceramic body has a grooved surface, within which are recessed mounting holes for a sink and a faucet. The upper surface of the grooved surface has multiple parallel strip-shaped drainage grooves. The ends of the strip-shaped drainage grooves are connected to the sink mounting holes. The bottom of each strip-shaped drainage groove has an inclined angle. The depth of the strip-shaped drainage groove near the sink mounting hole is greater than the depth of the strip-shaped drainage groove away from the sink mounting hole. The surface of the strip-shaped drainage grooves, the surface of the ceramic body, and the surface of the grooved surface are integrally glazed.
[0007] Preferably, there are two sink mounting holes and two faucet mounting holes. The two sink mounting holes are located on the left and right sides inside the groove surface, respectively, and the strip-shaped drain groove is located between the two sink mounting holes. The two faucet mounting holes correspond to the two sink mounting holes.
[0008] Preferably, the two ends of the strip-shaped drain groove are respectively connected to two water tank mounting holes, and the bottom of the strip-shaped drain groove gradually slopes downward from the middle to both ends.
[0009] Preferably, a partition plate is provided between the two water tank mounting holes, and both ends of the partition plate are connected to the ceramic surface; the strip-shaped drain grooves are located on both sides of the partition plate, and the upper surface of the partition plate is flush with the upper surface of the ceramic surface.
[0010] Preferably, the left and right sides of the partition plate are inclined surfaces between the two water tank mounting holes.
[0011] Preferably, the ceramic surface and the edge of the groove surface are smoothly transitioned by a bevel.
[0012] This invention provides a bidirectional, anti-slip, dish-shaped ceramic work surface with the following advantages: When water splashes onto the upper surface of the grooved surface, it first flows into the strip-shaped drain. Because the bottom of the strip-shaped drain is designed with an inclined angle, and the end closest to the water tank mounting hole is the lowest, gravity allows water to flow smoothly along the strip-shaped drain into the water tank mounting hole, effectively preventing direct overflow and ensuring the dryness and cleanliness of the work surface. It also effectively improves the overall anti-slip effect of the ceramic work surface. Furthermore, the partition ensures that the two water tank mounting holes are independent, effectively preventing lateral water flow between the two spaces and maintaining the classification and cleanliness of experimental equipment. This effectively reduces the possibility of cross-contamination, making the use of the work surface safer and more efficient. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0020] Example 1, as Figure 1As shown, a bidirectional flow-guiding anti-slip drip tray ceramic countertop includes a ceramic surface 1. A groove 2 is formed on the upper surface of the ceramic surface 1. In this embodiment, the edges of the ceramic surface 1 and the groove 2 are smoothly transitioned by a bevel, so that the edge of the groove 2 forms an integrated dish-shaped water-blocking edge. The dish-shaped water-blocking edge effectively prevents water overflow, ensuring that water droplets flow back along the bevel to the strip-shaped drip tray. A water tray mounting hole 3 and a faucet mounting hole 5 are formed inside the groove 2. Multiple interconnected... Parallel strip-shaped drain grooves 4 are connected at their ends to the water tank mounting holes 3. The bottom of the strip-shaped drain grooves 4 is inclined at an angle. The depth of the strip-shaped drain grooves 4 at the end near the water tank mounting holes 3 is greater than the depth of the end away from the water tank mounting holes 3. The surface of the strip-shaped drain grooves 4, the surface of the ceramic surface 1, and the surface of the groove surface 2 are all integrally fired with glaze, rather than being damaged later to create grooves. This ensures that the entire surface of the strip-shaped drain grooves 4, the ceramic surface 1, and the groove surface 2 is more resistant to pollution and easier to clean.
[0021] Working principle:
[0022] Firstly, a groove 2 is created on the upper surface of the ceramic surface 1, so that both the sink mounting hole 3 and the faucet mounting hole 5 are located within the groove 2, thus blocking water through the groove 2. During the cleaning of experimental equipment, when water splashes onto the upper surface of the groove 2, it first flows into the strip-shaped drain trough 4. Because the bottom of the strip-shaped drain trough 4 is designed with an inclined angle, and the end of the strip-shaped drain trough 4 is the lowest, gravity allows the water to flow smoothly along the strip-shaped drain trough 4 into the sink mounting hole 3, effectively preventing water from overflowing and ensuring the dryness and cleanliness of the experimental tabletop. In addition, by arranging multiple strip-shaped drain troughs 4 in parallel, the anti-slip effect of the entire ceramic tabletop is also effectively improved.
[0023] In Example 2, as a further preferred embodiment of Example 1, two water tank mounting holes 3 and two faucet mounting holes 5 are provided. The two water tank mounting holes 3 are located on the left and right sides inside the groove surface 2, respectively, and the strip-shaped drain groove 4 is located between the two water tank mounting holes 3; the two faucet mounting holes 5 correspond to the two water tank mounting holes 3. The two water tank mounting holes 3 form two relatively independent water tank spaces. This not only facilitates the classification and cleaning of experimental equipment but also improves water efficiency and avoids water waste.
[0024] In Example 3, as a further preferred embodiment of Example 2, the two ends of the strip-shaped drain trough 4 are connected to two water tank mounting holes 3, and the bottom of the strip-shaped drain trough 4 gradually slopes downward from the middle to both ends. Therefore, firstly, two relatively independent water tank spaces are formed through the two water tank mounting holes 3. Secondly, by setting the bottom of the strip-shaped drain trough 4 as a triangular inclined structure with a higher middle and lower ends, the water flow naturally converges to the water tank mounting holes 3 at both ends, thereby achieving a rapid drainage effect. Furthermore, the tilt angle can be adjusted to ensure that the work surface remains clean and dry under different experimental environments.
[0025] Example 4, as Figure 2 As shown, in a further preferred embodiment, a partition plate 6 is provided between the two water tank mounting holes 3, with both ends of the partition plate 6 connected to the ceramic surface 1. Strip-shaped drainage channels 4 are located on both sides of the partition plate 6, and the upper surface of the partition plate 6 is flush with the upper surface of the ceramic surface 1. The partition plate 6 ensures that the spaces of the two water tank mounting holes 3 are independent, effectively preventing water from flowing laterally between the two spaces and maintaining the classification and cleanliness of the experimental equipment. This effectively reduces the possibility of cross-contamination, making the use of the experimental platform safer and more efficient.
[0026] Example 5, such as Figure 3 As shown, in a further preferred embodiment of the second embodiment, the left and right sides of the partition plate 6 are inclined surfaces between the two water tank mounting holes 3. This makes the cross-sectional shape of the entire groove surface 2 a trapezoidal structure. This allows the water from the two independent water tanks to be independently guided into their respective water tank mounting holes 3, thus avoiding mixing and contamination between different experimental equipment.
[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
