Description

The present invention relates to a drainage port lid for covering a drainage port provided in a bathroom, a kitchen sink, or the like.

As a specific example of the drainage palate, there is one described in Patent Document 1.
The drainage port lid described in the same document is provided in a series with a lid main body portion in which a plurality of slits for water flow are provided in the central portion and are arranged so as to cover the drainage port, and a lower portion of the outer peripheral edge of the lid main body portion. It is provided with a flange-shaped locking portion on which a solid drug containing a microorganism growth inhibitor can be placed.
According to such a configuration, when the drainage that has passed through the plurality of slits comes into contact with the chemical, the chemical is dissolved and the dissolved liquid flows to the drain port. This makes it possible to remove slime from the drainage port.

However, in the above-mentioned prior art, there is still room for improvement as described below.

First, since the drug is arranged below the outer peripheral edge of the lid body, the solution of the drug does not reach the lid body above the drug in the drainage palate. Therefore, slime is generated in a wide range of the lid main body portion, and this portion becomes unsanitary.
Secondly, since the solid chemicals are arranged in a scattered manner along the circumference of the drainage port, it is difficult for the chemicals to be splashed with water, and it is difficult to efficiently generate a solution of the chemicals. Even if a relatively large amount of water is splashed on the drug, the solution of the drug often flows downward in a streak pattern toward the bottom of the solid drug, and it is difficult for the drug to spread over a wide area in the drain. For this reason, it is difficult to efficiently remove slime in a wide area in the drainage port.
Thirdly, as a means for holding the drug in the drainage palate, a means for continuously providing a collar-shaped locking portion on the lower surface side of the lid main body portion is adopted, so that the structure of this portion becomes complicated. The more complicated the structure of the drainage palate, the easier it is for dirt to adhere to it, and the more difficult it is to remove dirt when washing the drainage palate. Dirt often contains fine solids, fibers, and the like, but it is difficult to remove such dirt by the action of a chemical agent. Therefore, the lid main body is liable to become dirty and becomes more unsanitary.

Japanese Patent No. 4612297

The present invention has been conceived under the above-mentioned circumstances, and a drainage palate capable of allowing a predetermined drug to act rationally and effectively to be more hygienic than before. The challenge is to provide.

In order to solve the above problems, the following technical measures are taken in the present invention.

The drainage port lid provided by the present invention has a plate-shaped portion provided with a plurality of through holes for water passage penetrating in the vertical thickness direction, and has a lid main body portion arranged so as to cover the drainage port. A drug-containing member that is porous and has water permeability, and contains or can contain a drug for disinfecting, cleaning, antifungal, and deodorizing the drainage port. And, the drug-containing member has a main body portion arranged to be laminated on the lower surface side of the plate-shaped portion, and projects upward from the upper surface portion of the main body portion to fit into the plurality of through holes. It is characterized by having a plurality of fitting convex portions.

According to such a configuration, when the drainage flows over the plurality of through holes of the lid main body portion, the drainage is discharged from the upper surface of the fitting convex portion of the drug-containing member fitted in the plurality of through holes. It penetrates into the drug-containing member and causes the drug contained in the drug-containing member to flow out (including elution) from the main body of the drug-containing member below the main body. This spilled chemical exerts a sterilizing, cleaning, antifungal, or deodorizing effect on the drain. In addition to these, according to the present invention, the following effects can be further obtained.
First, of the lid main body, the lower surface of the plate-shaped portion and the inner surfaces of the plurality of through holes have a structure covered with or close to the drug-containing member. The drug contained in the drug-containing member can act directly. Therefore, unlike the conventional technique, the effect of sanitizing the lid main body can be obtained.
Secondly, the main body of the drug-containing member can be provided in a size having a large bottom area equivalent to that of the plate-shaped portion of the lid main body, while the drug can be provided from various places on the lower surface of the drug-containing member. It can be drained below it. Therefore, unlike the above-mentioned prior art, it is possible to prevent the solution from flowing from the solid drug in a streak pattern and to make the drug effectively act on a wide range in the drain port.
Thirdly, the drug is contained in the drug-containing member, and unlike the prior art, it is not necessary to provide a collar-shaped locking portion for placing and holding the solid drug. Further, as a means for attaching the drug-containing member to the lid main body portion, it is not necessary to additionally provide a complicated structural portion to the lid main body portion, and the attachment structure can be simplified. Therefore, it is possible to appropriately avoid that the structure of the drainage palate is complicated and the stain is likely to occur. In addition, the simplification of the structure makes it possible to reduce the manufacturing cost.
Fourth, since the drug-containing member also has an inset convex portion in addition to the main body portion, the thickness of the entire drug-containing member is thicker than, for example, when the drug-containing member is composed of only the main body portion. It is possible to take a large size and volume. Therefore, the amount of the drug that can be contained in the drug-containing member can be increased. This is preferable for enhancing the effect of the drug or eliminating the consumption of the entire amount of the drug contained in the drug-containing member in a short period of time.

In the present invention, preferably, the upper ends of the plurality of fitting convex portions are substantially flush with the upper surface of the plate-shaped portions.

According to such a configuration, it is possible to prevent a large uneven portion or a stepped portion from being generated on the upper surface of the plate-shaped portion and to make it difficult for dust or the like to be caught on the upper surface of the plate-shaped portion. Therefore, the lid main body can be made more hygienic.

In the present invention, preferably, the drug-containing member can be removed from the lid body.

With such a configuration, it is possible to replace the drug-containing member, which is convenient.

In the present invention, preferably, the plurality of through holes and the plurality of fitting convex portions are both upwardly widened.

According to such a configuration, when a downward force acts on the drug-containing member, each fitting convex portion does not easily come out from the through hole, and a coming-out prevention effect can be obtained. Therefore, it is possible to prevent the drug-containing member from being inadvertently detached from the lid main body and falling during the handling of the drainage port lid.
Further, by utilizing the retaining effect, it is possible to appropriately hold the entire drug-containing member in the lid main body portion, and it is also possible to eliminate the need to hold the drug-containing member in the plate-shaped portion by using another member. .. Further, since the area of the upper end surface of each fitting convex portion can be increased, it is possible to allow a large amount of drainage to enter the drug-containing member from the upper end surface of each fitting convex portion.

In the present invention, preferably, the drug-containing member is made of foamed resin, and the plurality of fitting convex portions are made of a material having a higher foaming ratio than the main body portion.

According to such a configuration, in the case of assembling the drainage palate, when a plurality of fitting convex portions are fitted into a plurality of through holes, the plurality of fitting convex portions are compressed and deformed into a plurality of through holes. It becomes possible to fit it, and the work becomes easy. On the other hand, the main body of the drug-containing member can have appropriate hardness and strength.

In the present invention, the drug-containing member is preferably white or white, and is colored by using a drug having a color other than white or white as the drug, corresponding to the content of the drug. It is configured so that the color changes.

According to such a configuration, the user can easily and accurately detect the remaining amount of the drug contained in the drug-containing member based on the color change described above, which is convenient.

In the present invention, preferably, a plate-shaped or sheet-shaped auxiliary member which is laminated on the lower surface side of the drug-containing member and has a plurality of water passage holes for allowing water flowing out from the drug-containing member to pass downward is further provided. I have.

According to such a configuration, it is possible to control how water flows downward from the auxiliary member by the number of water passage holes of the auxiliary member, the opening area, the arrangement, and the like. Unlike the above configuration, if the water containing the drug is simply flowed down from the lower surface of the drug-containing member without providing the auxiliary member, for example, the flow rate becomes excessive and the entire amount of the drug is consumed in a short period of time. May cause problems such as. On the other hand, according to the above configuration, it is possible to appropriately solve such a problem.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

(A) is a perspective view showing an example of a drainage palate according to the present invention, and (b) is a cross-sectional view showing an example of a usage state of the drainage palate shown in (a), and a cross-sectional portion of the drainage palate. Is Ib-Ib of (a). (A) is an exploded cross-sectional view of the drainage palate shown in FIG. 1, and (b) is a cross-sectional view showing another example of a drug-containing member used in the drainage palate. It is sectional drawing which shows the other example of this invention. It is sectional drawing which shows the other example of this invention.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The drainage palate A shown in FIG. 1 is a bathroom drainage palate for closing the upper opening of the drainage port 9 of the bathroom (including the shower room), and is a relatively hard resin lid main body 1, polyurethane foam, or the like. The chemical-containing member 2 made of foamed resin is provided.

The lid main body 1 is a plate-shaped portion 10 having a substantially rectangular shape in a plan view, and a plurality of elongated rectangular (or slit-shaped) through holes 11 penetrating the plate-shaped portion 10 in the vertical thickness direction (also in FIG. 2A). (See), a plurality of leg portions 13 projecting downward from the lower surface portions of the four corners of the plate-shaped portion 10, and a pair of protruding portions 12 projecting from the front surface portion of the plate-shaped portion 10. As shown in FIG. 1 (b), the lid main body 1 is fitted and arranged in the upper surface opening-shaped recess 80 formed above the drain port 9 in the bathroom floor 8. The pair of protrusions 12 are for entering the lateral recess 81 formed on the side wall of the recess 80, and are useful for preventing the drainage palate A from being installed in the wrong direction.

In the state where the drainage port lid A is arranged in the recess 80 as described above, a gap C is formed around the lid main body 1, and a large amount of water flows into the drainage port 9 from this gap C. There is. Water that has crossed the gap C, shower water from above the drainage port lid A, or the like reaches the position of the through hole 11 on the upper surface of the lid main body 1. A filter 7 having a mesh structure for collecting dust is provided above the upper end opening of the drain port 9.

As described above, the drug-containing member 2 is made of foamed resin, is porous with water permeability, and is elastically deformable. The drug-containing member 2 contains, for example, a liquid drug (including impregnation). As the chemical, for example, an existing disinfectant / cleaning solution used for cleaning the kitchen can be used, and specific components thereof and the like are omitted. Since the drug-containing member 2 is porous and has water absorption, the drug can be easily contained in the drug-containing member 2 by the user adding the drug.

Preferably, the drug-containing member 2 is white or white, and as the drug, one having a color other than white or white is used. According to such a configuration, the drug-containing member 2 is colored in the color of the drug in the state of containing the drug, and the color intensity (saturation) corresponds to the content of the drug. It will change. Therefore, based on this color depth, the user can easily detect the remaining amount of the drug in the drug-containing member 2.

The drug-containing member 2 includes a substantially flat body portion 20 and a plurality of fitting convex portions 21 projecting upward from the upper surface portion of the main body portion 20. The main body portion 20 is arranged so as to be laminated on the lower surface side of the plate-shaped portion 10 of the lid main body portion 1. The plurality of fitting convex portions 21 are fitted into the plurality of through holes 11 of the lid main body portion 1. The upper end of each fitting convex portion 21 is substantially flush with the upper surface of the plate-shaped portion 10. According to such a configuration, the upper surface of the drainage port lid A has no or few unevenness or steps, so that it is possible to prevent dust from being caught in this area. However, the present invention is not limited to this. The upper end of the fitting convex portion 21 may be made higher or lower than the upper surface of the plate-shaped portion 10.

Both the through hole 11 and the fitting convex portion 21 have an upwardly expanding shape, and in this state, they are tightly fitted to each other. According to such a fitting state, the fitting convex portion 21 is restricted from being displaced downward with respect to the through hole 11. In the present embodiment, the drug-containing member 2 is held by the lid main body 1 by utilizing such an action. However, since the fitting convex portion 21 is elastically deformable, the fitting convex portion 21 is pulled out from the through hole 11 by strongly pulling the main body portion 20 downward, and the drug-containing member 2 is separated from the lid main body portion 1. It is possible to make it.

When assembling the drainage palate A, the fitting convex portion 21 is made to enter the through hole 11 in the state shown in FIG. 2A, but the maximum width W1 of the fitting convex portion 21 is the minimum width W2 of the through hole 11. Greater than. Therefore, the approaching work is performed while compressing and deforming the fitting convex portion 21 so as to have a width smaller than the minimum width W2.

Preferably, the foaming ratio of each part of the drug-containing member 2 is non-uniform, and the foaming ratio Ra of the resin constituting the plurality of fitting convex portions 21 is higher than the foaming ratio Rb of the resin constituting the main body portion 20. It has been raised. This makes it possible to facilitate the fitting work into the through hole 11 by making the fitting convex portion 21 a portion that is easily elastically deformed while setting the main body portion 20 to an appropriate hardness and strength. Further, if the expansion ratio Ra of the fitting convex portion 21 is increased, the degree of the void portion in the porous structure is increased, so that it is possible to promote the permeation of water into the fitting convex portion 21.

In the natural state where the fitting convex portion 21 is not fitted into the through hole 11, the fitting convex portion 21 can be formed to have a rectangular cross section, for example, as shown in FIG. 2 (b). Even with such a shape, when the fitting convex portion 21 is fitted into the through hole 11, it becomes an upward spread shape that matches the through hole 11 due to elastic deformation.

Next, the operation of the drainage palate A described above will be described.

First, the drainage palate A is used in the manner shown in FIG. 1 (b). When water flows over the upper surface of the drainage palate A, a part of the water permeates into the drug-containing member 2 from the upper surface of the fitting convex portion 21 of the drug-containing member 2 and enters the inside of the drug-containing member 2. Going down. Eventually, the water flows downward from the lower surface of the drug-containing member 2, but at that time, the drug also flows out. As a result, the filter 7 and the inner peripheral wall of the drain port 9 are sterilized and cleaned.

Here, the drug can flow downward from various places on the lower surface of the drug-containing member 2. Here, the filter 7 is one of the parts where slime and the like are most likely to occur, but in the structure of FIG. 1B, the drug may flow down from the drug-containing member 2 to the entire upper surface of the filter 7. It is possible. Therefore, the sterilization / cleaning of the filter 7 is performed more efficiently and appropriately than in the case where the chemical is only allowed to flow around the edge of the filter 7.

On the other hand, the drug-containing member 2 covers the lower surface of the plate-shaped portion 10 of the lid main body 1 and the inner surfaces of the plurality of through holes 11, and the drug contained in the drug-containing member 2 acts directly on those portions. To do. Therefore, it is possible to prevent slime and the like from being generated on the lower surface of the plate-shaped portion 10 and the inside of each through hole 11, and to make the lid main body portion 1 itself hygienic.

Since the main body 20 of the drug-containing member 2 can be formed into a relatively large size having an area equivalent to that of the lower surface of the plate-shaped portion 10 of the lid main body 1, it is included in the drug-containing member 2. The amount of drug obtained can be increased. Further, since the drug can be contained in the plurality of fitting convex portions 21, the amount of the drug that can be contained in the entire drug-containing member 2 can be further increased. Therefore, it is possible to appropriately avoid that the entire amount of the drug contained in the drug-containing member 2 is consumed in a short period of time. In particular, in the present embodiment, as described above, most of the water flowing on the bathroom floor 8 flows into the gap C around the drainage palate A, flows onto the upper surface of the drainage palate A, and then the drug-containing member. Since the amount of water that permeates into 2 can be made appropriate, excessive outflow of the drug from the drug-containing member 2 is more thoroughly prevented. It is also possible to avoid a shortage of drug outflow.

When the drug content of the drug-containing member 2 decreases, the drug may be added to and replenished with the drug-containing member 2 while the drug-containing member 2 is held by the lid main body 1. Therefore, the work is easy. If the drug-containing member 2 is damaged for some reason, it is necessary to replace it. However, to remove the drug-containing member 2, the drug-containing member 2 is pulled below the lid main body 1. It can be done by itself and is easy. Further, when mounting the drug-containing member 2, it is necessary to fit each fitting convex portion 21 into each through hole 11, but such fitting work is also compared by compressing and deforming each fitting convex portion 21. It can be done easily.

3 and 4 show other embodiments of the present invention. In these figures, elements that are the same as or similar to those of the embodiment are designated by the same reference numerals as those of the embodiment, and duplicate description thereof will be omitted.

In the drainage palate Aa shown in FIG. 3, the auxiliary member 4 is laminated and joined to the lower surface portion of the drug-containing member 2. The auxiliary member 4 is in the shape of a plate or a sheet having a plurality of water passage holes 40 for allowing water flowing out from the drug-containing member 2 to pass downward. The auxiliary member 4 is joined to the drug-containing member 2 by using, for example, an adhesive. However, if the adhesive is applied over a large area, the water permeability of the drug-containing member 2 is impaired, so that the area where the adhesive is applied is narrow.

According to the present embodiment, the water (including the drug) that has passed through the drug-containing member 2 further passes through the water passage holes 40 of the auxiliary member 4 and flows down below them. Therefore, the above-mentioned way of flowing down the water can be controlled to a desired state by the number, opening area, arrangement, etc. of the water passage holes 40 of the auxiliary member 4.

In the drainage palate Ab shown in FIG. 4, the through hole 11 of the lid main body 1 and the fitting convex portion 21 of the drug-containing member 2 are not formed in an upward spreading shape, and the inner wall surface and the side surface thereof are not formed. , Non-tilted. On the other hand, the auxiliary member 4 having a plurality of water passage holes 40 is attached to the lid main body 1 by, for example, being locked to the locking convex 18 of the lid main body 1.

In the present embodiment, since the through hole 11 and the fitting convex portion 21 are not fitted in a state where they can be prevented from coming off downward, unlike the previous embodiment, the drug-containing member 2 is used alone. Although it cannot be held by the lid main body 1 with the above, the drug-containing member 2 can be appropriately supported by the auxiliary member 4.
As understood from the present embodiment, the through hole 11 and the fitting convex portion 21 can have a shape other than the upward spread. It is also possible to put the drug-containing member 2 in a state of being assembled to the lid main body 1 by using an appropriate member.

The present invention is not limited to the contents of the above-described embodiments. The specific configuration of each part of the drainage palate according to the present invention can be variously redesigned within the scope intended by the present invention.

The plurality of through holes for water flow provided in the lid body are not limited to an elongated rectangular shape or a slit shape, but can be made into other shapes, and have a specific size, number, arrangement, etc. Is not limited. The fitting convex portion of the drug-containing member corresponds to the configuration of such a through hole.

The drug-containing member may be porous at least having water permeability and may have a structure capable of containing the intended drug, and its specific shape, size, and material are not limited. Further, the drug-containing member does not have to contain the drug from the beginning (at the stage of being sold to the user), and even if the specification is such that the drug is separately prepared when the user starts using the drug. Good.

As the chemical, it is sufficient that at least one of the disinfectant, cleaning, antifungal, and deodorant of the drain outlet is used, and the specific component thereof is not limited. In addition to the liquid, the drug may be in the form of powder, for example, and may be kneaded into the drug-containing member. The drug-containing member may be of a type in which the drug-containing member is replaced with a new drug-containing member when the entire amount of the contained drug is consumed.

The drainage palate according to the present invention can be configured as, for example, a drainage palate for a kitchen sink, instead of being configured as a drainage palate for a bathroom. The location and type of drainage port does not matter.
