Description

  The present invention relates to a drain outlet cover for a sink that suppresses clogging of a dust removal net attached to a net basket and generation of bad odor.

  As a conventional drain outlet cover of a sink, there is a split-shaped one in which a disk-shaped rubber plate is cut out radially from the center hole toward the periphery to form a plurality of elastic tongue pieces. This is because the elastic tongues are always elastically held approximately horizontally, and the elastic tongues are bent downward by the flowing water pressure flowing from the drain port, so that the washed leftovers and vegetable waste fall smoothly into the net basket. It has become.

  Various lids for drain outlets made of synthetic resin have been proposed, but the flow of drainage is smooth, the remaining rice and vegetable scraps are washed away smoothly, and the inside of the strainer is concealed so that it can not be seen. Japanese Patent Application Laid-Open No. 2001-20341 discloses an appearance that effectively prevents small items such as those from falling into the strainer. This structure is a synthetic resin drainage lid that is detachably attached to the drainage opening formed on the bottom surface of the sink sink through a strainer, and is provided with a step formed in the inner periphery of the strainer. An outer edge portion that fits into the surface portion, a top plate portion that is continuous with the outer edge portion in at least two places so as to straddle the outer edge portion, and a groove is recessed in the circumferential direction at each of the continuous portions; A plurality of downward curved water guide portions projecting inward from the outer edge portion where the plate portion is not continuous, and an opening communicating with the inside of the strainer between the inner ends of the water guide portions, The end of the groove formed below the top plate and provided on the top plate was opened above the water guide.

  However, the rubber-made disc-shaped drainage lid of the sink is restored in a state where the elastic tongue piece gradually weakens its elastic restoring force with use and the tip of the elastic tongue piece hangs downward. There was a fear of not going. In this case, the net basket in which trash was put was exposed from the outside, and the appearance became worse and an unhygienic impression was given. Further, since the elastic tongue is easily bent downward by running water or the like, small items such as a spoon easily fall into the net basket when washing. Furthermore, when exposed to hot water, detergent, etc., the rubber deteriorates relatively early, resulting in inferior durability.

  On the other hand, Japanese Patent Laid-Open No. 2001-20341 discloses that water flows into the center side from two places (both sides), and the trash is shifted to one side of the net cage, which was a defect of the conventional synthetic resin drainage lid. Although the obstruction is solved to some extent, fine garbage is attached around the net cage, and the bacteria are prone to filth and adhesion due to breeding of various fungi, so it is necessary to clean the net cage regularly. I had to. This dirty net basket looked bad and was slimy and very filthy, so it was hated to clean the net basket.

For this reason, there are many cases in which a dust removal net is attached to the inner side of a net basket in a rubber or synthetic resin drain cover. In this case, since fine dust adheres to the dust removal net, the dust in the net basket is reduced by frequently exchanging the dust removal net, and the interval for cleaning the net basket is very long. However, if you install a garbage collection net inside the mesh basket and wash the bran pickles, or if you wash off dirt such as a muddy soup mixed with small particles, the eyes of the garbage collection net will immediately clog and water will enter the net. Since the overflow and the sink overflow, the current situation is that even when there is not much garbage in the garbage collection net, it is replaced. In particular, when Japanese Patent Application Laid-Open No. 2001-20341 is used, when the amount of drainage increases, the same amount of water flows down from both sides into the mesh basket, so that convection of dust is likely to occur in the mesh basket, and the dust rises and dust is removed. Garbage adheres to the side of the net and causes clogging. In addition, if the falling water flow from both sides balances and air escape cannot be ensured, bubbles will come out intermittently, creating turbulent flow in the mesh basket each time, and garbage in the mesh basket will be agitated. There were problems such as the possibility of reverse flow to the sink side. If the dust removal net is clogged, it may be possible to remove the clogging of the dust removal net with a brush or the like. Since the net is clogged and the unit price of the trash removal net is low, the trash removal net is replaced without removing the clogging with a brush or the like.
JP 2001-20341 A

  The present invention provides a sink drain cover that can prevent clogging of a dust removal net attached to a net basket and can store a large amount of garbage, reduce the amount of use of the dust removal net, and suppress the generation of bad odors. The purpose is to provide.

  The present invention has been made to solve the above problems, that is, an annular outer frame fitted to the inner periphery of the drain opening opened at the bottom of the sink, and provided at the center of the outer frame. It comprises at least a flat cylindrical body that opens downward, and a plurality of guide vanes that are disposed between the outer frame and the cylindrical body and guide the drainage in a spiral shape. Further, the guide vanes may be attached by inclining downward along the inner circumference of the outer frame and inclining outward. A cleaning agent storage portion is formed in the center of the cylindrical body, and the cleaning agent storage portion has a solid cleaning. It is good to store the agent.

In particular, the clogging that occurred when the garbage collection net was attached to the inside of the mesh basket was drastically reduced, and it could be used effectively until the garbage collection net was filled with garbage, and the exchange of the garbage collection net was reduced. Become. In addition, even when washing bran pickles or muddy soup, which was previously in trouble, it is possible to eliminate clogging of the dust removal net, eliminating overflow and reducing the number of times the dust removal net is replaced. You can concentrate on preparing meals and cleaning up, and you can do it smoothly. Further, even when the amount of drainage increases, each guide vane (3) causes the drainage to flow in a spiral shape, so that smooth drainage is possible and there is no fear of backflow of garbage. Moreover, the garbage in the mesh basket attached to the drainage port is hidden, making it difficult for spoons and chopsticks to fall into the garbage collection net from the opening.

  By attaching the guide vane (3) as inclining downward along the inner periphery of the outer frame (1) and inclining outward as in claim 2, the drainage can be reliably performed along the inner periphery of the mesh basket. Since it falls while rotating, it does not cause small particles of dust to adhere to the eyes of the dust removal net attached to the inside of the net basket, and is carried along with the drainage, making it difficult to clog the net.

  By storing the cleaning agent (5) in the cleaning agent storage portion (4) in the center of the cylinder (2) as shown in claim 3, malodor inside the net basket is reduced.

  As shown in claim 4, as the cleaning agent storage section (4), the cleaning agent (5) can be stored, and the storage main body (41) that opens upward, and can be attached to the upper portion of the storage main body (41).

A curved surface is formed (see FIG. 3). In addition, the said cleaning agent storage part (4) does not necessarily need to be formed. Further, the size of the cleaning agent storage portion (4) is set to an intermediate size between the cylinder (2) and the cleaning agent storage portion (4) in the figure, and the guide blade (3) is connected to the outer frame ( It is good also as what is arrange | positioned between 1) and a washing | cleaning agent accommodating part (4). When the hole (41b) is drilled in the bottom surface of the storage body (41), the bottom of the cylindrical body (2) is inclined downward so that the waste water flowing out of the hole (41b) It is preferable to reach the circumference. (5) is a solid, water-soluble cleaning agent stored in the cleaning agent storage unit (4). As the cleaning agent (5), it is preferable to use a mixture of a deodorant and a fragrance. .

  Next, how to use the present invention will be described. First of all, when installing the device of the present invention, a dust removal net is previously attached to the inside of the net basket. First, grasp the outer periphery of the cylindrical body (2) with a finger on the opening side of the guide vane (3). Then, by fitting the outer frame (1) to the inner periphery of the drain port, the attachment of the inventive product is completed. Next, when the inside of the garbage collection net is filled with raw garbage, grasp the outer periphery of the cylinder (2) with your fingers as described above, remove the device from the drainage port, and place it on the bottom of the sink. In addition, remove the garbage collection net from the basket and dispose of it. After disposal, a new dust removal net may be attached to the inside of the net basket and the inventive device may be attached to the drain outlet as described above.

  In addition, when using a device of the present invention in which the cleaning agent (5) is stored in the center of the cylindrical body (2), a dust removal net is previously attached to the inside of the net basket. Moreover, the lid | cover (42) of a cleaning agent storage part (4) is removed, a solid cleaning agent (5) is stored in a storage main body (41), and the lid | cover (42) is made to adhere to the upper part. Then, the inventive device may be set and used as described above. Thereafter, when the inside of the garbage collection net is filled with raw garbage, the outer periphery of the cylindrical body (2) is grasped with a finger as described above, removed from the drainage port, and placed on the bottom surface of the sink. In addition, remove the garbage collection net from the basket and dispose of it. After disposal, install a new garbage collection net inside the mesh basket. At this time, if the cleaning agent (5) is small, a new solid cleaning agent (5) is prepared, and after the lid (42) is removed, a new cleaning agent ( 5) is housed, and a lid (42) is attached to the upper portion thereof, and the device of the present invention may be attached to the drain outlet as described above.

  The operation of the present invention will be described. Attach this product to the drain in advance. At this time, as shown in FIG. 2 and FIG. 3, a solid cleaning agent (5) is stored in the cleaning agent storage part (4), and a deodorant and a fragrance are mixed in the cleaning agent (5). Use things. First, when dishes and vegetables are washed, the garbage is guided to the guide vane (3) together with the drainage and falls while rotating clockwise. At this time, when garbage and wastewater enter the inner side from the outer frame (1), they fall and flow while tilting outward to reach the opening. At the same time, in addition to the guide vanes (3), one drainage enters the inside from the intake (42b) provided on the outer periphery of the lid (42) of the cleaning agent storage (4). When this drainage enters from the intake (42b) as shown by the arrow in FIG. 3, it passes through the side surface from the upper surface of the cleaning agent (5). After that, the dissolved cleaning agent (5) and waste water flow out from the hole (41b) provided on the outer periphery of the bottom surface of the storage body (41), and further through the bottom of the cylindrical body (2), the upper part of the mesh basket. The cleaning agent (5) dissolved in the inner periphery and the wastewater reach.

  From the opening, the garbage, the drainage, and the dissolved cleaning agent (5) fall along the inner circumference of the dust removal net and while rotating to the right. The fallen garbage is sequentially deposited from the bottom of the garbage collection net, and the waste water and the dissolved cleaning agent (5) fall through the mesh basket and fall into the drain pipe. When the garbage falls along the inner circumference of the garbage collection net, it falls together with vigorous drainage, so the fine particles of garbage fall before the eyes of the garbage collection net are clogged. The conventional clogging of the dust removal net is almost eliminated. Accordingly, even when the bran pickles are washed away, or when the soup that is mixed with small particles is washed away, it can be performed without worrying about clogging. In addition, if there is dust adhering to the inner periphery of the dust removal net, the dust is washed away by the momentum of the drainage. Furthermore, since the solid cleaning agent (5) is stored inside the cleaning agent storage part (4), even if garbage such as dishes and vegetables are collected inside the garbage collection net, their smell is Since it is eliminated by the deodorant component or the fragrance component, or the odor is drastically reduced, the sink can be kept clean.
