Description

[Technical Field]

[0001] The present invention relates to a drain cover that improves design by covering the drain outlet of a tank body. [Background technology]

[0002] A widely known structure treats wastewater generated inside a tank body, such as a bathtub or washbasin, by providing a drain outlet on the bottom or side of the tank body and discharging the wastewater downstream through piping. However, the inside of the piping is prone to accumulate dirt such as scale and dust, which can be visible to users and detract from the design aesthetic. While a drain outlet may be formed in the tank body by watertightly attaching a component such as a drain outlet fitting to an opening in the tank body, the adhesion of such dirt and dust to the joint between the tank body and the component forming the drain outlet also detracts from the design aesthetic. For this reason, a method is known in which the drain outlet is covered with a cover to prevent the design aesthetic from being compromised.

[0003] The drain outlet cover member described in Patent Document 1 comprises a disk-shaped cover portion, a shaft portion extending below the cover portion, and a dirt collection portion formed on the shaft portion, with the diameter of the cover portion being larger than the circle formed by the seam between the member forming the drain outlet and the tank body. The dirt collection portion is attached to the shaft portion by a screw thread. When the cover member is placed on the drain outlet, the cover portion conceals the drain outlet of the tank body and its surroundings, thereby concealing the inside of the drain outlet of the tank body and the seam between the member forming the tank body and the drain outlet, preventing users from seeing scale, dust, and other debris adhering to the drain outlet and the seam, thereby improving the design. Furthermore, when the cover member is inserted into the drain outlet provided on the bottom surface of the tank body, the lower end of the dirt collection unit formed on the back surface of the cover member abuts on a step formed inside the drain outlet, thereby being installed in the drain outlet, and the cover member, which is formed by connecting the dirt collection unit with a shaft, further forms a gap between the tank body, the drain outlet, and the cover member. When wastewater is generated inside the tank body, it flows from the gap into the drain outlet and is discharged downstream through the piping member. In this way, the cover member described in Patent Document 1 improves design by covering the drain outlet, while forming a gap that allows wastewater to be discharged from the drain outlet.

[0004] Furthermore, the drain outlet lid member described in Patent Document 2 comprises a lid portion that covers the drain outlet, a dirt collection portion placed on top of the drain outlet, and a support portion configured below the lid portion that allows the lid portion and the dirt collection portion to be attached, and the lid portion is detachably attached to the dirt collection portion. Also, by placing the dirt collection portion on the upper edge of the drain outlet, the lid member is placed above the drain outlet, and when the lid portion is placed on the drain outlet, the lid portion conceals the inside of the drain outlet of the tank body (the dirt collected in the dirt collection portion and the inside of the drain outlet that is contaminated by wastewater), preventing the user from seeing the scale and dust adhering to the dirt collection portion and inside the drain outlet, thereby improving design.

[0005] [Patent Document 1] Jitsuto No. 3104134 [Patent Document 2] Patent Publication No. 2019-19509 Summary of the Invention [Problem to be solved by the invention]

[0006] In the drain cover described in Patent Document 1, if dirt was trapped in the dirt collection section or if slime or other contaminants adhered to the dirt collection section itself, the user had to clean the dirt collection section, but the dirt collection section was small and required time and effort to clean with a brush or the like, and if dirt, slime, or black spots accumulated in the mesh of the dirt collection section during drainage, cleaning with a brush sometimes was not enough to remove the dirt.Even if dirt that could not be removed by washing had accumulated and accumulated, and the user wanted to replace only the dirt collection section, they had to replace the entire drain cover. Furthermore, even if a user wanted to replace only the lid to match the tank body or the interior decor of the room, the user had to replace the entire drain cover. Furthermore, because the dust collection unit is attached to the inside of the drain outlet, it is designed to match the shape of the drain outlet of the tank body. However, the inner shape of the drain outlet varies depending on the specifications and shapes of the drain outlet and tank body manufacturers, making replacing the dust collection unit itself difficult. In contrast, the diameter of the drain outlet of the lid is determined by a standard, so the diameter rarely varies between drain outlet and tank body manufacturers. For this reason, when replacing the entire drain outlet lid, if the shape of the dust collection unit does not match the drain outlet, the drain outlet lid cannot be installed on the drain outlet. Furthermore, in the technology of Patent Document 1, the lid and the dust collection unit are connected by a threaded engagement. Therefore, even if the shape of the dust collection unit does not match the drain outlet, even if an attempt was made to separate the lid and the dust collection unit and attach only the lid to the drain outlet, it was impossible to attach only the lid to the drain outlet because the lid is attached and fixed to the dust collection unit by a shaft.

[0007] Furthermore, in the drain cover described in Patent Document 2, the dirt collection unit is placed on top of the drain and attached to the drain, so it can be attached to the drain even if the shape of the dirt collection unit does not match the inner circumferential shape of the drain, and is therefore not affected by the shapes of the drain or the tank. However, because the lid is attached to the dirt collection unit, the lid cannot be installed on the drain without installing the dirt collection unit. Therefore, if there is no need to install a dirt collection unit on the drain, such as when the drain already has a dirt collection unit attached, even if you try to separate the dirt collection unit from the lid and attach only the lid to the drain, the lid is attached to the dirt collection unit, so it is impossible to attach the lid to a drain that does not support the dirt collection unit.

[0008] The present invention was invented in consideration of the above-mentioned problems, and provides a drain cover that allows the user to replace only the lid or only the dirt collection part, depending on the user's choice, and that makes it possible to use only the lid by utilizing the existing dirt collection part regardless of the shape of the drain.

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following description is intended to facilitate understanding of the embodiments, and is not intended to limit or limit the scope of the present invention. As shown in Figure 1, the tank body 1 is a concave washbasin with an open top, and has a drain outlet 2 formed in the bottom surface 11 and an overflow drain outlet 22 formed in the side surface 12. The tank body 1 is placed on a cabinet C, and piping components such as a drain trap are installed inside the cabinet C.

[0016] The drain fitting 3 is hollow and cylindrical, forming a drainage flow path inside, and has a cylindrical tube portion 31 and a brim-like flange portion 32, and is attached to an opening drilled in the bottom surface 11 of the tank body 1 to form the drain outlet 2 for draining hot and cold water from the tank body 1. In this embodiment, the corner formed by the inner surface of the tube portion 31 of the drain outlet 2 and the upper surface of the flange portion 32 is the edge portion 21 of the opening of the drain outlet 2. The tubular portion 31 is cylindrical with a male thread formed on its outer surface, and is screwed onto a nut 4 on the back surface of the tank body 1. In addition, an opening is formed on the side surface of the tubular portion 31 so that the drainage water from the overflow drain outlet 22 can join. The flange portion 32 is brim-shaped and extends outward from the upper end of the tubular portion 31, and when the drain outlet fitting 3 is attached to the tank body 1, it abuts against the periphery of the opening drilled in the bottom surface 11 via a gasket. A piping member such as a drain trap is connected to the drain fitting 3 on the downstream side, and drainage water flowing in from the drain outlet 2 and the overflow drain outlet 22 is discharged downstream. As shown in Figures 2 to 6, the drain cover 9 consists of a cover portion 5, an attachment portion 52 provided below the cover portion 5, a garbage collection portion 6, and a covering member 8, and is a member that is placed on the drain 2 to cover and conceal the inside of the drain 2 and the drain fittings 3 so that they cannot be seen. The cover 5 is a circular plate-like member having the same or larger diameter as the flange 32 of the drain fitting 3. On the drain 2 side, i.e., the lower side in Figure 4, it comprises a shaft 51 as the connection part 7, a first connection part 71, an attachment part 52, and a female thread part 54 that screws into the connection part 7. In this embodiment, the shaft 51 is detachably attached to the cover 5. A covering member 8 made of a metal material is attached to the top surface of the cover 5. Note that in Figure 1, parts of the shaft 51 and covering member 8 that are not visible due to the attachment part 52 are shown with dashed lines. The female thread part 54 screws into a male thread part 73 formed at the upper end of the connection part 7. The shaft 51 serving as the connecting part 7 is a cylindrical member extending from the center of the lid 5 toward the drain outlet 2, and in this embodiment is configured as a separate member from the lid 5. As shown in Figure 4, the upper end of the connecting part 7 (shaft 51) is provided with a male thread 73 that screws into the female thread of the lid, allowing the connecting part 7 to be attached to the lid in a detachable manner. A first connecting part 71 is formed at the lower end of the connecting part 7. The first connecting portion 71 is a groove recessed around the entire circumference of the shaft portion 51 near the lower end of the shaft portion 51, and when the drain outlet cover 9 is assembled, it engages freely with the second connecting portion 72 of the garbage collection portion 6. As shown in Fig. 3, when viewed from the bottom, the mounting portion 52 is a rib formed radially at four locations, spaced 90 degrees apart from the center of the lid portion 5, and when the drain outlet lid 9 is placed on the drain outlet 2, as shown in Fig. 3, it engages with the edge 21 of the opening of the drain outlet 2, thereby forming a gap space S between the lid portion 5 and the drain outlet 2 through which wastewater passes. In addition, the mounting portion 52 has an inclined surface 53 that slopes toward the center of the lid portion 5 as it moves toward the end. The inclined surface 53 has a bent portion 53a in the middle, and the portion closer to the lid 5 than the bent portion 53a is generally arc-shaped, but a straight portion 53b is formed below the bent portion 53a. When the drain outlet cover 9 is placed on the drain outlet 2, the straight portion 53b contacts the inner surface of the drain outlet 2 below the edge portion 21, thereby positioning the drain outlet cover 9. As shown in Figure 3, the outer surface of the inclined surface 53 located radially outward of the lid 5 has a flat portion 53c that contacts the edge portion 21 of the opening of the drain outlet 2 in a cross-sectional view. The dirt collection part 6 is a member that is disposed inside the drain outlet 2 and captures hair, dust, and the like while draining, and is selectively detachably attached to the lid part 5. The dirt collection part 6 also includes a bearing part 61, a second connecting part 72, an annular part 62, and a collection part 63. The bearing portion 61 is a cylindrical hollow body formed in the center of the dirt collection portion 6, and a second connection portion 72 is formed on the inner surface. The second connecting portion 72 is a protrusion formed inward from the inner surface of the bearing portion 61 and engages with the first connecting portion 71 of the cover portion 5 . The annular portion 62 is annular in shape and has an outer diameter that is approximately the same as the inner surface of the drain outlet fitting 3 . The collecting portion 63 is a mesh that collects hair, dust, and the like in the drainage water, and is formed so as to connect the outer surface of the bearing portion 61 and the inner surface of the annular portion 62 . In this embodiment, after removing the connecting part 7, the screw hole (actual hole) of the female thread part 54 formed on the back surface of the lid part 5 is exposed, and to close this hole, a cap K is inserted into the screw hole to seal it. This prevents wastewater from flowing into the screw hole during use, which can cause dirt and scale to accumulate.

[0017] When the drain outlet cover 9 of the present invention is placed on the drain outlet 2, the cover portion 5 covers and conceals the joint between the drain outlet 2 and the flange portion 32 and the tank body 1, thereby improving the design of the washbasin. In addition, the attachment portion 52 of the drain outlet cover 9 is engaged with the edge portion 21 of the opening of the drain outlet 2, thereby forming a gap space S between the drain outlet 2 and the cover portion 5, and wastewater can pass through the gap space S and be discharged from the drain outlet 2. Furthermore, the drain outlet cover 9 is configured so that the attachment part 52 engages with the edge part 21 of the opening of the drain outlet 2, rather than with the bottom surface 11 of the tank body 1 or the upper surface of the flange part 32. This makes it possible to reduce the contact area with the tank body 1, so that when the drain outlet cover 9 is subjected to an impact, the inner surface of the tank body 1 or the drain outlet fitting 3 is less likely to be seriously damaged. Furthermore, since the straight portion 53b abuts against the inner surface of the drain outlet 2 and the flat portion 53c of the mounting portion 52 abuts against the edge portion 21 of the opening of the drain outlet 2, the drain outlet cover 9 can be positioned stably without tilting relative to the drain outlet 2.

[0018] Furthermore, in the drain cover 9 of the present invention, the mounting portion 52 has an inclined surface 53 that slopes toward the center of the cover 5 the further away from the cover 5, and is configured so that the mounting portion 52 engages with the edge 21 when the inclined surface 53 abuts against the edge 21. This makes it possible to place the drain cover 9 even if the diameter of the drain 2 is different, as described below. When the drain cover 9 is placed on a drain 2 of a different diameter, a dirt collection portion 6 that fits the inner diameter of the drain 2 is appropriately attached to the cover 5.

[0019] The drain outlet cover configured in this manner is attached as follows by a builder at the construction site of the tank body 1 or by a user at the time of actual use. The dirt collection unit 6 is placed inside the drain 2 to be installed, and it is confirmed that the dirt collection unit 6 can be placed so that it fits the internal shape of the drain fitting 3. If the dirt collection unit 6 fits the internal shape of the drain fitting 3, the drain lid is simply attached to the drain 2 as shown in FIG. 2, and installation is complete. If the dirt collection unit 6 becomes very dirty after long-term use, the dirt collection unit 6 can be removed by pulling the dirt collection unit 6 downward from the lid 5, which will release the connection between the first connecting portion 71 and the second connecting portion 72. The shaft 51 of the lid 5 is then pulled out from the bearing 61 of the dirt collection unit 6, and the dirt collection unit 6 can be removed from the lid 5 and the dirt collection unit 6. Then, the bearing 61 of a new dirt collection unit 6 is inserted into the shaft 51 of the lid 5, and the first connecting portion 71 and the second connecting portion 72 are engaged and connected, allowing the dirt collection unit 6 to be attached to the lid 5. Furthermore, if the user wishes to change the surface color or surface finish of the lid portion 5 to match the interior design or the design of the tank body 1, multiple color and surface finish patterns for the lid portion 5 can be prepared, allowing the user to change only the lid portion 5 as needed to match the interior design or the design of the tank body 1. Furthermore, if the dust collection unit 6 does not fit the internal shape of the drain fitting 3 during the aforementioned confirmation process and the lid 5 cannot be placed on the drain 2, the existing dust collection unit 6' already installed on the drain 2 can be used as is, as shown in FIG. 6 , and the dust collection unit 6 can be removed from the lid 5 of the drain lid 9 and only the lid 5 can be placed on the drain 2. When the user rotates the shaft 51 serving as the connection unit 7 on the back of the lid 5, the male thread 73 of the connection unit 7 and the female thread 54 of the lid 5 are disengaged as shown in FIG. 4 , and the connection unit 7 is removed from the lid. Then, the threaded hole of the female thread 54 of the lid 5 is sealed with a cap K to prevent wastewater from flowing into the threaded hole. Since the lid 5 includes the attachment unit 52, the lid 5 can be attached to the drain 2 regardless of whether the dust collection unit 6 is installed or not, and regardless of the internal shape of the drain 2. For these reasons, whether or not to employ the dust collection unit 6 can be selected appropriately by the user or installer.

[0020] Although the embodiments of the present invention have been described above, the present invention is not limited to the shapes of the respective embodiments, and appropriate modifications may be made within the scope of the gist of the invention. For example, although the tank body 1 in the above-described embodiments is a washbasin, it may be a bathtub, sink, or other tank body. In the above embodiment, the drain outlet cover 9 is disposed at the drain outlet 2 formed on the bottom surface 11 of the tank body 1, but it may be disposed at the overflow drain outlet 22 formed on the side surface 12 of the tank body 1. Also, the valve body of the tank body 1 may be used as a pop-up valve that moves the valve body up and down by a remotely configured operating unit.

[0021] In the above-described embodiment, the connection portion 7 is configured as a separate unit from the lid portion 5 or the dust collection portion 6 and is separably attached to either the lid portion 5 or the dust collection portion 6. However, as shown in FIG. 7 , the connection portion 7 may be configured as an integral part of either the lid portion 5 or the dust collection portion 6, and a kerf 74 for separation or cutting may be provided to separate the connection portion 7 from the lid portion 5 or the dust collection portion 6. By providing the kerf 74 to enable cutting, the user can easily separate the connection portion on-site, improving workability. The kerf 74 can also be used as a guide when cutting with a saw, scissors, cutter, or the like. In addition to the kerf, a marker for separation or cutting to separate the connection portion 7 from the lid portion 5 or the dust collection portion 6 may be provided. The marker may be provided by printing or a sticker, or may be a convex rib or a concave groove. In addition, in the above embodiment, the shaft portion 51 serving as the connecting portion 7 is configured in the lid portion 5, and the bearing portion 61 is configured in the dust collection portion 6, but as shown in Figure 8 or Figure 9, the shaft portion 64 serving as the connecting portion 7 may be configured in the dust collection portion 6, and the bearing portion 55 may be configured in the lid portion 5. Furthermore, in the above embodiment, the mounting portion 52 is configured to have a cross shape when viewed from the bottom, but although not shown, it may also have a cylindrical guide shape that matches the inner peripheral shape of the drain outlet 2.
