Description

  The present invention relates to a drain outlet lid having a slime removing function that is mounted on a drain outlet such as a sink.

  Conventionally, as a drain outlet cover for a sink, a disc-shaped rubber plate having an edge portion is provided with a plurality of elastic tongue pieces that are radially cut from the center portion (chrysanthemum shape). The drain port lid closes the drain port by fitting it to a drain port (actually a strainer provided in the drain port) opened on the bottom surface of the sink and mounting an edge. In this drain cover, the elastic tongue pieces are normally held in an almost horizontal position so that the garbage basket stored in the drain port is closed from the outside and cannot be seen from the outside. When using the sink, the elastic tongues bend downward due to the water pressure flowing into the drain port, and waste such as waste or vegetable waste washed away by the water smoothly falls into the strainer's mesh basket. It is like that.

  By the way, it is known that when a sink is used, slime and off-flavor are generated in the drainage opening, particularly in the strainer net. It is known that this slime and off-flavor is caused by substances secreted from bacteria that adhere to garbage collected in a net cage and use it as a nutrient source. For this reason, it has been proposed that the slime removing agent is accommodated in a plastic net or a basket-like container, and this is suspended in a net cage by a string or the like to suppress slime (for example, see Patent Document 1). ). In other words, hanging the slime remover on the handle of the mesh basket via a string or the like can suppress the slime of the mesh basket. However, when removing and discarding the garbage in the mesh basket, put the slime remover There was a problem that it was difficult to take out the trash from the net basket.

In addition, as a drain outlet lid of a sink, a container in which a slime removing agent is accommodated in the vicinity of the peripheral edge of a disc-shaped lid body that is mounted so as to close the drain outlet has been proposed (for example, Patent Document 2, 3). This drain outlet lid is provided with an accommodating portion for accommodating the slime removing agent on the back surface in the vicinity of the peripheral edge portion of the lid main body. A water inflow hole is provided on the surface in the vicinity of the peripheral edge portion of the lid main body, and water flows into the accommodating portion from the water inflow hole. A discharge hole is provided in the lower part of the storage unit, and water in which the slime-removing agent is dissolved in the storage unit is discharged from the discharge hole into the drain. As described above, since the slime remover is accommodated in the drain outlet lid, the slime remover does not interfere with throwing away the dust in the drain outlet, for example, the dust in the net basket.

After the suspension, as shown in FIG. 1, the drain cover 1 is fitted to the fitting step 13 of the drain 12 so that the lid main body 2 contacts the flange 15 a of the mesh cage 15. Accordingly, the drain port lid 1 is attached to the drain port 12 so that the surface of the lid body 2 is positioned substantially on the same plane as the bottom surface of the sink 11 or slightly below the bottom surface.

When water flows through the sink 11, the water flows from the sink 11 onto the lid body 2. This water flows from the top of the lid body 2 to the drainage section 4, and this flow is guided toward the slime removing container 3 on the back surface of the lid body 2 through the drainage guide section 8 and the drainage guide hole 8a. . That is, water flows toward the slime removing container 3 and enters the slime removing container 3 through the numerous water inlet / outlet holes 33, and the slime removing chemical 9 accommodated in the slime removing container 3 is dissolved in the water. Is done. This water is discharged from the water inlet / outlet 33 of the slime removing container 3. In this way, the water in which the slime-removing agent 9 is dissolved flows into the mesh basket 15 and the drain port 12, so that the mesh basket 15 and the drain port 12 can be particularly suppressed. At this time, since the drain port 12 is usually provided at the lowest position of the sink 11, the water tends to flow on the lid body 2 inward in the radial direction. Therefore, it is possible to reliably suppress the slime.

Even if the flow of water flowing from the sink 11 onto the drain outlet lid 1 is uneven, the water flows through the drainage part 4 and the drainage guide part 8 and the drainage guide hole 8a regardless of this deviation. Since it is always guided to the take-up container 3, the slime-removing drug 9 dissolves in water without any deviation. As a result, the water in which the slime-removing agent 9 is well dissolved can be allowed to flow out to the mesh basket 15 and the drain port 12 without frequently refilling the slime-removing agent 9.

Further, when the slime-removing agent 9 is lost or decreased, the drain port lid 1 is taken out from the fitting step portion 13 of the drain port 12. The slime removing container 3 of the drain outlet lid 1 is pushed from the back surface of the lid body 2 toward the front surface. Thereby, the flange 32 of the slime removing container 3 is detached from the fitting portion 22 of the lid main body 2, and the accommodating portion 31 is extracted from the mounting hole 21, whereby the slime removing container 3 can be easily taken out from the lid main body 2. The first container 3 a and the second container 3 b of the slime removing container 3 are opened, and the slime removing drug 9 is accommodated in the accommodating portion 31. The slime-removing container 3 is mounted on the lid body 2, and the drainage port lid 1 is fitted into the fitting step portion 13 of the drainage port 12, thereby completing the refilling of the slime-removing drug 9. Therefore, the first drainage lid 1 according to the present invention can easily refill the slime-removing drug 9.

The

When water flows through the sink 11, the water flows from the sink 11 onto the edge member 105 and the cover body 106. This water flows from the edge member 105 and the cover body 106 to the drainage portion 104, and this flow is radially inward of the cover body 106 (center portion of the cover body 106) by the drainage guide portion 108 and the drainage guide hole 108a . You will be guided towards. That is, water flows toward the slime removing container 103, water flows in the slime removing container 103, and the slime removing chemical 109 contained in the slime removing container 103 is dissolved in the water. This water is discharged from the drain 12 through the net cage 15. In this way, the water in which the slime-removing agent 109 is dissolved flows into the mesh basket 15 and the drain port 12, so that the mesh basket 15 and the drain port 12 can be suppressed in particular. At this time, since the drain port 12 is usually provided at the lowest position of the sink 11, the water easily flows on the lid main body 102 in the radial inward direction. Therefore, it is possible to reliably suppress the slime.

Further, the water flowing from the sink 11 onto the drain cover 101 does not flow evenly into the four drainage portions, although depending on the amount of water, and there are places where the water can easily flow and difficult to flow. The water flowing on the lid 101 can be biased. Thus, even if there is a bias in the flow of water, the water is always guided to one slime removing container 103 through the drainage part 104 and the drainage guide part 108 regardless of this bias. Dissolves in water without bias. As a result, the water in which the slime-removing agent 9 is well dissolved can be allowed to flow out to the mesh basket 15 and the drain port 12 without frequently refilling the slime-removing agent 109.

Further, when the slime-removing agent 109 is lost or decreased, the drain port lid 101 is taken out from the fitting step portion 13 of the drain port 12. The slime removing container 103 of the drain cover 101 is pushed from the back surface of the cover body 106 toward the front surface.
