Description

Technical Field

[0001] The present invention relates to a sink, in particular to a sink with a hidden drain. Background Art

[0002] The sink is an important hardware product for kitchen work at home. In current technology, whether it is center drainage or rear drainage, during the process of users cleaning food or kitchen utensils, the sundries generated will be isolated by the filter screen or basket of the drainer on the visible surface of the drain hole. Even small food residues or sundries are clearly visible in the kitchen, which affects the cleanliness and beauty of the kitchen. Moreover, when the drain hole is connected to a garbage disposal unit, during the operation of the garbage disposal unit, the high-speed grinding process may cause the crushed food residues to splash out, affecting the use by customers. Summary of the Invention

[0003] In view of the above defects, the present invention provides a sink with a hidden drain, which can cover the drain hole, hide the garbage on the visible surface of the drain hole, and does not affect drainage, increasing the cleanliness and beauty of the kitchen.

[0004] In order to achieve the above invention object, the present invention provides the following technical solutions:

[0005] A sink with a hidden drain includes a sink body, a step, a cover plate, and a drain hole. The sink body is provided with a step, an opening is provided on the step, the drain hole is provided on the sink body below the opening, the cover plate is installed at the opening of the step, and a gap is provided between the cover plate and the sink surface of the sink body.

[0006] Preferably, the cover plate is movably installed at the opening of the step in a rotatable manner. The cover plate includes an upper plate and a lower plate, and the upper plate and the lower plate are connected at a certain angle. The cover plate can be opened or closed to hide or expose the covered drain hole.

[0007] Preferably, the cover plate is movably installed on the step through support pins and flange nuts. Two rotation holes are provided on the cover plate, and cover plate installation holes are correspondingly provided on both sides of the sink body. The support pins pass through the rotation holes and the cover plate installation holes and are connected to the flange nuts. Such an installation method can not only ensure that the cover plate can be rotated and is not fixed, but also ensure stable installation and not easy to fall off.

[0008] Preferably, a washer is provided between the support pin and the cover plate installation hole, and a spring washer is provided between the flange nut and the cover plate installation hole. The washer can increase the contact area between the support pin and the cover plate installation hole, reduce the pressure between the support pin and the device, so as to play a protective role. The spring washer can reduce vibration and prevent the flange nut from loosening.

[0009] Preferably, a stop block is provided between the upper plate and the step. The stop block is arranged on the right side surface of the sink body. There is a stop block mounting hole on the right side surface of the sink body, and a gasket is provided on the stop block mounting hole. The stop block is fixed to the right side surface of the sink by a screw passing through the gasket and the stop block mounting hole. The stop block can limit the movement of the upper plate towards the drain hole, so as to avoid the upper plate continuing to move downward due to the action of gravity, resulting in a poor hiding effect of the cover plate or even losing the function of hiding the drain hole.

[0010] Preferably, the step and the upper plate form an integral plane, and the stop block is assembled to limit the upper plate to the same horizontal plane as the step plane, so that the upper plate and the step plane can form an integral plane for placing items.

[0011] Preferably, a counterweight is provided on the lower plate. The counterweight can increase the gravity of the lower plate, making the lower plate heavier than the upper plate. In the natural state, the lower plate will drive the upper plate to move downward. When the lower plate moves to be perpendicular to the sink plane, the counterweight reaches the lowest point and there is no gravitational potential energy to drive the lower plate to continue moving. The lower plate stays in the situation perpendicular to the sink plane, thus eliminating the need for manual restoration operation.

[0012] Preferably, a drainer is provided on the drain hole. When the drain hole is connected to the drainer, during the process of the user cleaning food and kitchen utensils, the cover plate is closed, and the garbage generated by the user flows along the water through the gap between the cover plate and the sink surface of the sink body to the drainer, and is isolated on the filter screen or basket by the drainer. The cover plate can cover the drainer, so that the isolated garbage cannot be observed by other people entering the kitchen, thereby improving the cleanliness and beauty of the kitchen.

[0013] Preferably, the cover plate is made of a translucent material, which can enable the user of the sink to directly see the situation of the garbage accumulated in the drainer to determine the cleaning time. Opening the cover plate can clean the accumulated garbage, and the drainer will not be blocked due to the garbage on the filter screen or basket not being cleaned for too long.

[0014] Preferably, a garbage processor is provided on the drain hole, and the cover plate blocks the garbage processor. Thus, when the garbage processor is working, the splashing food residues will be blocked by the cover plate, preventing them from soiling the kitchen and affecting the use by the customer.

[0015] Specifically, the present invention has the following advantages:

[0016] In the present invention, the drain hole is placed on the sink body below the opening of the step, and a cover plate is installed at the opening of the step. The cover plate is installed at the opening of the step and is located above the drain hole. There is a slight gap between the cover plate and the sink surface. The gap between the cover plate and the sink surface allows garbage to pass through. The garbage generated by the user can flow along with the water through the gap into the drain hole. Moreover, the cover plate can also cover the drain hole, so that the garbage hidden on the visible surface of the drain hole cannot be observed by people entering the kitchen, improving the cleanliness and beauty of the kitchen.

[0017] Compared with the prior art, in the prior art, generally a water-sealing cover is used to seal the drain hole to prevent the garbage at the drain hole from being observed by people entering the kitchen. However, the water-sealing cover will block the water flow. As long as the water-sealing cover is sealed at the drain hole to block the drain hole, the water flow cannot pass through, and the garbage generated by the user cannot flow into the drain hole along with the water flow. Instead, the user has to manually open the water-sealing cover to drain the water, which greatly affects the user experience.

[0018] Therefore, the present invention provides a sink with a hidden drain, which can cover the drain hole, hide the garbage on the visible surface of the drain hole, and does not affect drainage, increasing the cleanliness and beauty of the kitchen. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please refer to Figures 1 - 5 , Figure 1 which is a schematic side view structure diagram of the cover plate being opened in the present invention; Figure 2 which is a schematic side view structure diagram of the cover plate being closed in the present invention; Figure 3 which is a schematic top view structure diagram of the water outlet hole without a water outlet device installed in the present invention; Figure 4 which is a schematic top view structure diagram of the water outlet hole with a water outlet device installed in the present invention; Figure 5 which is a schematic overall structure diagram of the cover plate in the present invention.

[0030] The present invention provides a water outlet hidden sink. The component names corresponding to the reference numerals in the figure are as follows: sink body 1, step 2, cover plate 3, water outlet hole 4, water outlet device 5, gap 6, upper plate 7, lower plate 8, support nail 9, flange nut 10, rotation hole 11, washer 12, spring washer 13, stop block 14, sealing gasket 15, screw 16, counterweight 17.

[0031] An under - water hidden sink, comprising a sink body 1, a step 2, a cover plate 3, and a drain hole 4. The sink body 1 is provided with a step 2, and an opening is provided on the step 2. The drain hole 4 is provided on the sink body 1 below the opening. The cover plate 3 is installed at the opening of the step 2, and a gap 6 is provided between the cover plate 3 and the sink surface of the sink body 1.

[0032] The cover plate 3 is movably installed at the opening of the step 2 in a rotatable manner. The cover plate 3 includes an upper plate 7 and a lower plate 8, which are connected at a certain angle. The cover plate 3 can be opened or closed to hide or expose the covered drain hole 4.

[0033] The cover plate 3 is movably installed on the step 2 through a support nail 9 and a flange nut 10. Two rotation holes 11 are provided on the cover plate 3, and corresponding cover - plate installation holes are provided on both sides of the sink body 1. The support nail 9 passes through the rotation hole 11 and the cover - plate installation hole and is connected to the flange nut 10. Such an installation method can not only ensure that the cover plate 3 can be rotated and is not fixed, but also ensure stable installation and is not easy to fall off.

[0034] A washer 12 is provided between the support nail 9 and the cover - plate installation hole, and a spring washer 13 is provided between the flange nut 10 and the cover - plate installation hole. The washer 12 can increase the contact area between the support nail 9 and the cover - plate installation hole, reduce the pressure between the support nail and the device, so as to play a protective role. The spring washer 13 can reduce vibration and prevent the flange nut 10 from loosening.

[0035] A stop block 14 is provided between the upper plate 7 and the step 2. The stop block 14 is provided on the right side surface of the sink body 1. A stop - block installation hole is provided on the right side surface of the sink body 1, and a gasket 15 is provided on the stop - block installation hole. The stop block 14 is fixed to the right side of the sink through a screw 16 passing through the gasket 15 and the stop - block installation hole. The stop block 14 can limit the movement of the upper plate 7 in the direction of the drain hole 4, so as to avoid the upper plate 7 continuing to move downward due to the action of gravity, resulting in a poor hiding effect of the cover plate 3 or even losing the function of hiding the drain hole 4.

[0036] Of course, the above - mentioned embodiment of realizing the limit through the baffle is only the preferred installation method in the limit device. Other limit devices that can limit the movement of the upper plate 7 in the direction of the drain hole 4 and have a principle similar to the above - mentioned embodiment are within the protection scope of the present invention.

[0037] The step 2 and the upper plate 7 form an integral plane. The stop block 14 can be assembled to limit the upper plate 7 to be in the same horizontal plane as the step 2 plane, so that the upper plate 7 can form an integral plane with the step 2 plane for placing items.

[0038] A counterweight 17 is provided on the lower plate 8. The counterweight 17 can increase the gravity of the lower plate 8, making the lower plate 8 heavier than the upper plate 7. In the natural state, the lower plate 8 will drive the upper plate 7 to move downward. When the lower plate 8 moves to be perpendicular to the plane of the water tank, the counterweight 17 reaches the lowest point, and there is no gravitational potential energy to drive the lower plate 8 to continue moving. The lower plate 8 stays in the situation perpendicular to the plane of the water tank, thus eliminating the operation of manually restoring it.

[0039] A drainer 5 is provided on the drain hole 4. When the drain hole 4 is connected to the drainer 5, during the process of the user cleaning food and kitchen utensils, the cover plate 3 is closed. The garbage generated by the user flows along the water through the gap 6 between the cover plate 3 and the water tank surface of the water tank main body 1 to the drainer 5, and is isolated on the filter screen or basket by the drainer 5. The cover plate 3 can cover the drainer 5, so that the isolated garbage cannot be observed by other people entering the kitchen, thereby improving the cleanliness and beauty of the kitchen.

[0040] The cover plate 3 is made of a translucent material, which can enable the user of the water tank to directly see the situation of the drainer 5 accumulating garbage, so as to determine the cleaning time. Opening the cover plate 3 can clean the accumulated garbage, and the drainer 5 will not be blocked due to the garbage on the filter screen or basket not being cleaned for too long.

[0041] Secondly, as another embodiment of the present invention, a garbage processor can also be provided on the drain hole 4, and the cover plate 3 shields the garbage processor. Thus, when the garbage processor is working, the splashing food residues will be blocked by the cover plate 3, and will not dirty the kitchen and affect the use by the customer.

[0042] The working and using method of the present invention is as follows:

[0043] When the drain hole 4 is connected to the drainer 5, during the daily use of the user, the cover plate 3 is closed. The cover plate 3 is limited by the limiting device, and the limiting device restricts the upper plate 7 to a position flush with the plane of the step 2, forming an integral plane, which can be used as a water filtering platform. During the process of the user cleaning food and kitchen utensils, the garbage generated by the user flows along the water to the drainer 5, and is isolated on the filter screen or basket by the drainer 5, and the cover plate 3 can cover the drainer 5; when the user of the water tank needs to clean the drainer 5, only need to rotate the upper plate 7 of the cover plate 3 counterclockwise by 180 degrees, so that the opening of the step 2 is completely exposed, and then the garbage in the drainer 5 can be directly cleaned. After cleaning, rotate the cover plate 3 clockwise by 180 degrees until the upper plate 7 is restricted by the limiting device and cannot continue to rotate in the direction of the drain hole 4.

[0044] When the drain hole 4 is connected to the garbage processor, close the cover plate 3, turn on the faucet to make the water flow into the garbage processor, then sweep the garbage into the garbage processor through the lower plate 8, and turn on the garbage processor. The garbage processor grinds the garbage into fine particles, and the water or food residues splashed during the grinding process are blocked by the cover plate 3.

[0045] Specifically, the present invention has the following advantages:

[0046] In the present invention, the drain hole 4 is placed on the sink body 1 below the opening of the step 2. A cover plate 3 is installed at the opening of the step 2. The cover plate 3 is installed at the opening of the step 2 and is located above the drain hole 4. A slight gap 6 is provided between the cover plate 3 and the sink surface. The gap 6 between the cover plate 3 and the sink surface allows garbage to pass through. The garbage generated by the user can flow along the water through the gap 6 into the drain hole 4. Moreover, the cover plate 3 can also cover the drain hole 4, so that the garbage hidden on the visible surface of the drain hole 4 cannot be observed by people entering the kitchen, improving the cleanliness and beauty of the kitchen.

[0047] Compared with the prior art, in the prior art, a water-sealing lid is generally used to seal the drain hole 4 to prevent the garbage at the drain hole 4 from being observed by people entering the kitchen. However, the water-sealing lid will block the water flow. As long as the water-sealing lid is sealed at the drain hole 4 to block the drain hole 4, the water flow cannot pass through, and the garbage generated by the user cannot flow into the drain hole 4 along with the water flow. Instead, the user has to manually open the water-sealing lid to drain the water, which greatly affects the user experience.

[0048] Compared with the prior art, the present invention provides a sink with a hidden drain, which can cover the drain hole, hide the garbage on the visible surface of the drain hole, and does not affect drainage, increasing the cleanliness and beauty of the kitchen.

[0049] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art in this technical field, without departing from the spirit and scope of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
