Description

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

There exists a thing of patent document 1 as a specific example of a drainage lid.
The drain outlet lid described in the same document is provided with a plurality of slits for water passage provided in the center portion, and a lid main body portion arranged so as to cover the drain outlet and a lower portion of the outer peripheral edge of the lid main body portion. And a hook-shaped locking portion on which a solid drug containing a microbial growth inhibitory substance can be placed.
According to such a configuration, when the wastewater that has passed through the plurality of slits touches the drug, the drug is dissolved, and this dissolved solution flows to the drain port. This makes it possible to remove the drainage outlet.

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

1stly, since a chemical | medical agent is a structure arrange | positioned under the outer periphery of a lid | cover main-body part, the solution solution of a chemical | medical agent does not reach the lid | cover main-body part which exists above a chemical | medical agent among drain outlet caps. Therefore, sliminess is generated in a wide range of the lid main body portion, and this portion becomes unsanitary.
Second, since the solid medicines are arranged in a scattered arrangement along the periphery of the drain outlet, it is difficult for the medicines to be splashed with water, and it is difficult to efficiently produce a medicine solution. Even if a relatively large amount of water is applied to the drug, the drug solution often flows in a streak pattern below the solid drug and is difficult to spread over a wide area in the drainage port. For this reason, it is difficult to efficiently remove a large area in the drain outlet.
Thirdly, as a means for holding the medicine in the drain outlet lid, a means for connecting a hook-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 drainage lid is, the more easily dirt is deposited, and it is difficult to remove the dirt when washing the drainage lid. In many cases, dirt contains fine solids, fibers, and the like, but it is difficult to remove such dirt by the action of a drug. Therefore, the lid main body part is easily contaminated and is further unsanitary.

Japanese Patent No. 4612297

  The present invention has been conceived under the circumstances as described above, and allows a predetermined medicine to act rationally and effectively, and is a drainage palate that can be made more hygienic than before. The challenge is to provide

  In order to solve the above problems, the present invention takes the following technical means.

The drain port lid provided by the present invention has a plate-like portion provided with a plurality of through holes for water passage penetrating in the vertical thickness direction, and a lid main body portion arranged so as to cover the drain port; A porous material having water permeability and containing or capable of containing a drug for at least one of sterilization, washing, mold prevention and deodorization of the drain outlet And the drug-containing member is placed on the lower surface side of the plate-like portion and is disposed so as to protrude upward from the upper surface portion of the main body portion and fit into the plurality of through holes. And a plurality of insertion convex portions.

According to such a configuration, when drainage flows onto the plurality of through holes of the lid main body portion, the drainage flows from the upper surface of the insertion convex portion of the drug-containing member inserted into the plurality of through holes. It penetrates into the drug-containing member, and the drug contained in the drug-containing member flows out (including elution) downward from the main body of the drug-containing member. This spilled drug exhibits sterilization, cleaning, antifungal, or deodorizing effects at the drain outlet. In addition to the above, according to the present invention, the following effects can be further obtained.
1stly, since the lower surface of a plate-shaped part and the inner surface of a some through-hole become a structure covered with the chemical | medical agent containing member or a structure close | similar to this among cover main body parts, with respect to those parts. The medicine contained in the medicine-containing member can be made to act directly. Therefore, unlike the prior art, an effect of sanitizing the lid main body can be obtained.
Secondly, the main body part of the drug-containing member can be provided with a size having a large bottom area comparable to the plate-like part of the lid main body part, while the drug is supplied from various places on the lower surface part of the drug-containing member. It can flow out downward. Therefore, unlike the prior art, it is possible to prevent the solution from flowing in a streak form from a solid drug, and to make the drug act effectively over a wide range in the drain.
Thirdly, the drug is contained in the drug-containing member, and unlike the prior art, it is not necessary to provide a hook-shaped locking portion for placing and holding the solid drug. In addition, as a means for attaching the drug-containing member to the lid main body portion, it is not necessary to separately add a complicated structure portion to the lid main body portion, and the attachment structure can be simplified. Therefore, it is possible to appropriately avoid the occurrence of contamination due to the complicated structure of the drainage lid. Further, the manufacturing cost can be reduced by simplifying the structure.
4thly, since the chemical | medical agent containing member also has a fitting convex-shaped part in addition to a main-body part, compared with the case where a chemical | medical agent-containing member is comprised only from a main-body part, for example, the thickness of the whole chemical | medical agent-containing member It is possible to increase the 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 fact that the entire amount of the drug contained in the drug-containing member is consumed 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-like portion.

  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-like portion, and to make it difficult for dust or the like to be caught on the upper surface of the plate-like portion. Therefore, it is possible to make the lid body portion more hygienic.

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

  According to such a configuration, it is possible to exchange the medicine-containing member, which is convenient.

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

According to such a structure, when downward force acts on a chemical | medical agent containing member, each insertion convex-shaped part does not come off easily from a through-hole, and the removal prevention effect is acquired. Therefore, it is possible to avoid that the medicine-containing member is carelessly detached from the lid main body portion and falls during handling of the drain port lid.
In addition, it is possible to appropriately hold the entire drug-containing member on the lid main body part by utilizing the retaining effect, and it is possible to eliminate the need to hold the drug-containing member on the plate-like part using another member. . Furthermore, since the area of the upper end surface of each insertion convex-shaped part can be taken large, it also becomes possible to let many waste_water | drains enter into a chemical | medical agent containing member from the upper end surface of each insertion convex-shaped part.

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

  According to such a configuration, when assembling the drain port lid, when inserting the plurality of insertion convex portions into the plurality of through holes, the plurality of insertion convex portions are compressed and deformed into the plurality of through holes. It becomes possible to insert, and the operation | work becomes easy. On the other hand, the body portion of the drug-containing member can have appropriate hardness and strength.

  In the present invention, preferably, the drug-containing member is white or white, and is colored when the drug has a color other than white or white, and corresponds to the content of the drug. The color is changed.

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

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

  According to such a configuration, it is possible to control the way the water flows down to the lower side of the auxiliary member by the number, the opening area, the arrangement, and the like of the auxiliary member. Unlike the above configuration, if the water containing the medicine is simply flowed down from the lower surface portion of the medicine-containing member without providing the auxiliary member, for example, the flow rate becomes excessive, and the whole amount of the medicine is consumed in a short period of time. Such a problem may occur. On the other hand, according to the said structure, it is possible to eliminate such a malfunction appropriately.

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

(A) is a perspective view which shows an example of the drainage lid which concerns on this invention, (b) is sectional drawing which shows an example of the use condition of the drainage lid shown to (a), Comprising: The cross-sectional location of a drainage lid Is Ib-Ib of (a). (A) is a disassembled sectional view of the drainage lid shown in FIG. 1, and (b) is a sectional view showing another example of the drug-containing member used in the drainage lid. 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.

  A drain outlet lid A shown in FIG. 1 is a drain outlet lid for a bathroom for closing an upper opening of a drain outlet 9 in a bathroom (including a shower room). The lid body 1 is made of a relatively hard resin, polyurethane foam, and the like. And a drug-containing member 2 made of foamed resin.

  The lid body 1 includes a plate-like portion 10 having a substantially rectangular shape in plan view, and a plurality of elongated rectangular (or slit-like) through holes 11 (FIG. 2A) penetrating in the vertical thickness direction of the plate-like portion 10. Reference), a plurality of leg portions 13 projecting downward from the lower surface portion of the four corners of the plate-like portion 10, and a pair of projection portions 12 protruding from the front surface portion of the plate-like portion 10. As shown in FIG. 1B, the lid main body 1 is fitted and disposed in a recess 80 having an upper surface opening shape formed in the bathroom floor 8 above the drain outlet 9. The pair of projecting portions 12 are for entering a laterally recessed portion 81 formed on the side wall of the recessed portion 80, and are useful for preventing the drain port lid A from being installed incorrectly.

  In the state where the drain outlet lid A is disposed in the recess 80 as described above, a gap C is generated around the lid main body 1, and a large amount of water flows into the drain outlet 9 from the gap C. Yes. Water that has passed through the gap C or shower water from above the drain outlet lid A 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 a foamed resin and is elastically deformable in addition to being porous with water permeability. The drug-containing member 2 contains, for example, a liquid drug (including impregnation). As the medicine, for example, an existing disinfecting / cleaning liquid used for kitchen cleaning or the like can be used, and specific components thereof are omitted. Since the medicine-containing member 2 is porous and has water absorption, the medicine can be easily contained in the medicine-containing member 2 when the user adds the medicine.

  Preferably, the drug-containing member 2 is white or white, and a drug 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 a state where the drug is contained, and the color density (saturation) corresponds to the content of the drug. Will change. Therefore, the user can easily perceive the remaining amount of the medicine in the medicine-containing member 2 based on the darkness of the color.

  The drug-containing member 2 includes a substantially flat main body portion 20 and a plurality of insertion convex portions 21 that protrude upward from the upper surface portion of the main body portion 20. The main body portion 20 is disposed on the lower surface side of the plate-like 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-like portion 10. According to such a configuration, since the upper surface of the drainage lid A has no or less unevenness or a step, it is possible to prevent dust from being caught in this region. However, the present invention is not limited to this. The upper end of the insertion convex portion 21 may be made higher or lower than the upper surface of the plate-like portion 10.

  Both the through-hole 11 and the fitting convex portion 21 have an upwardly expanding shape, and in this state, both are closely fitted. According to such a fitting state, the fitting convex portion 21 is restricted from being displaced downward relative to the through hole 11. In the present embodiment, the drug-containing member 2 is held by the lid main body 1 using such an action. However, since the insertion convex portion 21 can be elastically deformed, the insertion convex portion 21 is removed 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 lid A, in the state shown in FIG. 2A, the insertion convex portion 21 is made to enter the through hole 11, and the maximum width W1 of the insertion convex portion 21 is the minimum width W2 of the through hole 11. Bigger than. For this reason, the said approach operation | work will be performed, compressing and deforming so that the insertion convex-shaped part 21 may be made into the width | variety 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 insertion convex parts 21 is higher than the foaming ratio Rb of the resin constituting the main body part 20. It is high. As a result, it is possible to facilitate the fitting operation into the through-hole 11 by setting the fitting convex portion 21 to be easily elastically deformed while setting the main body portion 20 to appropriate hardness and strength. Further, if the expansion ratio Ra of the insertion 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 penetration of water into the insertion convex portion 21.

  The insertion convex portion 21 can be formed in a rectangular cross section as shown in FIG. 2B, for example, in a natural state where the insertion convex portion 21 is not inserted into the through hole 11. Even if it is such a shape, when the insertion convex-shaped part 21 is inserted in the through-hole 11, it will become an upward spreading shape corresponding to the through-hole 11 by elastic deformation.

  Next, the operation of the drainage lid A will be described.

  First, the drainage lid A is used in a mode as shown in FIG. When water flows on the upper surface of the drainage lid A, a part of the water penetrates into the drug-containing member 2 from the upper surface of the fitting convex portion 21 of the drug-containing member 2, and the inside of the drug-containing member 2. To descend. Eventually, the water flows downward from the lower surface portion of the drug-containing member 2, but also causes the drug to flow 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 out from various places on the lower surface of the drug-containing member 2 downward. Here, the filter 7 is one of the parts where the slime is most likely to occur. However, 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. Is possible. Therefore, the sterilization and washing of the filter 7 are performed more efficiently and appropriately than in the case where the medicine just flows around the edge of the filter 7.

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

  Since the main body portion 20 of the drug-containing member 2 can be formed in a relatively large size having the same area as the lower surface portion of the plate-like portion 10 of the lid main body portion 1, it is included in the drug-containing member 2. The amount of drug obtained can be increased. Moreover, since the chemical | medical agent can also be contained in the some insertion convex-shaped part 21, it is possible to increase the quantity of the chemical | medical agent which can be contained in the whole chemical | medical agent containing member 2 further. Therefore, it is possible to appropriately avoid that the entire amount of the medicine contained in the medicine-containing member 2 is consumed in a short period of time. In particular, in this embodiment, as described above, most of the water flowing on the bathroom floor 8 flows into the gap C around the drainage lid A and flows onto the upper surface of the drainage lid A before the medicine-containing member. Since the amount of water that permeates 2 can be made moderate, it is more thoroughly prevented that the medicine from the medicine-containing member 2 flows out excessively. It is also possible to avoid a shortage of drug outflow.

  When the drug content of the drug-containing member 2 is reduced, the drug-containing member 2 may be added and replenished while the drug-containing member 2 is held on the lid body 1. Therefore, the work is easy. When the drug-containing member 2 is damaged due to some reason, it is necessary to replace it. However, the drug-containing member 2 is removed by pulling the drug-containing member 2 below the lid main body 1. It can be done simply and easily. Further, when the drug-containing member 2 is attached, it is necessary to insert each insertion convex portion 21 into each through-hole 11, but such insertion work is also compared by compressing and deforming each insertion convex portion 21. This can be done easily.

  3 and 4 show another embodiment of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and redundant description thereof is omitted.

  In the drain cap Aa shown in FIG. 3, the auxiliary member 4 is laminated and bonded to the lower surface portion of the drug-containing member 2. The auxiliary member 4 has a plate shape or a sheet shape having a plurality of water passage holes 40 through which water flowing out from the drug-containing member 2 passes downward. The auxiliary member 4 is joined to the drug-containing member 2 by using, for example, an adhesive. However, since the water permeability of the medicine-containing member 2 is impaired when the adhesive is applied in a wide area, the adhesive application area is set to a narrow area.

  According to the present embodiment, the water (including the medicine) that has passed through the medicine-containing member 2 further flows through the water passage hole 40 of the auxiliary member 4, and flows down below these. Therefore, the way the water flows down can be controlled to a desired state by the number, the opening area, the arrangement, and the like of the water passage holes 40 of the auxiliary member 4.

  In the drain outlet lid 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 so as to expand upward. , 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 being locked to the locking convex portion 18 of the lid main body 1, for example.

In the present embodiment, the through-hole 11 and the fitting convex portion 21 are not fitted in a state in which the through-hole 11 and the fitting convex portion 21 are prevented from coming out downward. However, the medicine-containing member 2 can be appropriately supported by the auxiliary member 4 although it cannot be held by the lid body 1.
As can be understood from the present embodiment, the through-hole 11 and the fitting convex portion 21 can have a shape other than the upward spread. Moreover, it is also possible to make the chemical | medical agent containing member 2 into the state assembled | attached to the lid body part 1 using the appropriate member.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the drain outlet lid according to the present invention can be variously modified within the range intended by the present invention.

  The plurality of through holes for water passage provided in the lid main body are not limited to an elongated rectangular shape or a slit shape, and can be formed in other shapes, and a specific size, number, arrangement, etc. Is not limited. The insertion convex portion of the medicine-containing member corresponds to the configuration of such a through hole.

  The drug-containing member is at least porous so long as it has water permeability, and may have any configuration that can contain the intended drug, and its specific shape, size, and material are not limited. In addition, the medicine-containing member may not contain any medicine from the beginning (the stage where it is sold to the user), and may be configured to contain a separately prepared medicine when the user starts use. Good.

  As a chemical | medical agent, the thing for aiming at at least 1 among the sterilization of a drain outlet, washing | cleaning, mold prevention, and deodorization should just be used, The specific component etc. are not limited. In addition to liquid, the drug may be in the form of powder, for example, and kneaded into the drug-containing member. The medicine-containing member may be of a type that replaces the medicine-containing member with a new medicine-containing member when the entire amount of the contained medicine is consumed.

The drainage lid according to the present invention can be configured as a drainage lid for a kitchen sink, for example, instead of being configured as a bathroom drainage lid. The location and type of the drain outlet are not limited.
