Description

  The present invention relates to a drainage cover for covering a drainage port of a washing place.

  Some unit baths have a drain outlet formed at the bottom of a concave drain receiving portion provided on the floor of the washing place, and the drain outlet is covered with a lid fitted in the drain receiving portion (for example, Patent Documents 1 and 2).

  Patent Document 1 discloses a drainage pan made of synthetic resin that is fitted into a drainage receiving portion on the floor surface of a washing place and covers a drainage port. This drain pan is formed with a plurality of drain holes that penetrate from the front surface (surface on the washing ground side) to the back surface (surface on the drain port side), and drains from the gap between the side wall of the drain receptacle and the drain pan. In addition to flowing to the drain, drainage flows to the drain through a small drain hole. In this way, when a plurality of small drain holes are formed, the strength of the drain pan is reduced. Therefore, a plate-shaped reinforcing rib is provided on the back surface of the drain pan so that the small drain holes can be divided into plural pieces. There are several standing.

  On the other hand, Patent Literature 2 discloses an upper lid that is fitted into a drainage receiving portion on a floor surface of a washing place and covers a drainage port. In the upper lid, no drainage hole is formed on the surface (washing surface side), and the drainage flows from the gap between the sidewall of the drainage receiving portion and the upper lid to the drainage port.

  By the way, when a plurality of reinforcing ribs are provided on the back surface as in the drainage pan of Patent Document 1, these reinforcing ribs hinder the cleaning of the back surface, and the cleaning work becomes difficult (cleanability is reduced).

  On the other hand, when the drainage hole is not formed as in the upper cover of Patent Document 2, it is not necessary to reinforce with a reinforcing rib or the like, so that the back surface cleaning becomes easy. However, if a large amount of drainage flows suddenly to the drain outlet side, the drainage from the gap between the side wall of the drainage receiving part and the top lid will not be sufficient, and the drainage will overflow on the floor of the washing area and remain on the backside of the top lid. Due to the air, the upper lid is easily lifted from the depression.

  This invention makes it a subject to suppress the floating at the time of drainage, ensuring the drainage flow rate, and improving cleaning property.

The drain cover for the drain according to claim 1 is accommodated in a concave drain receptacle formed in a washing place, and the resin decorative plate portion covering the drain vent formed at the bottom of the drain receptacle, A through-hole formed in the decorative plate portion and penetrating from the washing area side to the drain port side, and formed around the through-hole on the drain port side of the decorative plate portion, along the thickness direction of the decorative plate portion A side wall surface that is inclined with respect to the plate thickness direction in the cross section, and a recess that is formed by the side wall surface and that the plate thickness of the decorative plate portion becomes thinner toward the through hole.

  In the decorative cover for a drain outlet according to claim 1, a through-hole penetrating from the washing place side to the drain opening side, that is, a through-hole communicating the washing place side and the drain opening side is formed in the decorative plate portion. Since the drainage of the washing place flows to the drainage opening through the gap between the drainage receiving part and the decorative board part and the through hole, for example, compared with the case where the through hole as described above is not formed in the decorative board part, The drainage flow rate to the drainage port can be secured.

  On the other hand, when a large amount of wastewater suddenly flows into the drainage receiving part and overflows from the drainage receiving part, the air on the drainage outlet side passes through the through hole of the decorative plate part and flows out to the washing place side. Compared to the case where the through hole is not formed in the plate part, the amount of air remaining on the drainage side of the decorative board part can be reduced, and the decorative board part from the drainage receiving part (that is, makeup for the drainage port) The lift of the lid) can be suppressed.

In particular, in the drain cover, the cross section along the plate thickness direction of the decorative plate portion (that is, the decorative plate portion is cut along the plate thickness direction of the decorative plate portion on the drain port side of the inclined plate portion). In the case of a large amount of drainage flowing into the drainage receiving portion as described above, the drainage port is formed as the thickness of the decorative plate portion on the side wall surface becomes thinner toward the through hole in the cross section). The air on the side is guided by the side wall surface of the depression and is sent to the bottom side of the depression, and escapes to the washing place side through a through hole opened at the bottom of the depression. That is, the above-described depression makes it difficult for air to remain on the side of the decorative board portion drainage port.
Therefore, it is possible to further reduce the amount of air remaining on the drain outlet side of the decorative plate portion during drainage, and to effectively suppress the floating from the drain receiving portion.

  Further, in the drain cover decorative cover, the thickness of the decorative plate portion on the side wall surface becomes thinner toward the through hole. For example, the thickness of the decorative plate portion on the side wall surface becomes the through hole. Compared to those that do not become thinner (for example, those whose side wall surfaces extend along the thickness direction of the decorative plate part), it is easier to put a cleaning tool or the like into the recess and facilitate cleaning (cleanability) Improved).

  In the above-described decorative cover for the drain port, since the depression is formed on the drain port side of the decorative plate portion, the decorative plate portion by reducing the resin material without impairing the beauty of the surface of the decorative plate portion on the washing place side. The weight can be reduced and the cost can be reduced.

  As described above, according to the decorative cover for a drain outlet, it is possible to suppress the lifting during drainage while ensuring the drainage flow rate, and to improve the cleaning performance.

  The drain opening decorative cover according to claim 2 is the drain opening decorative lid according to claim 1, wherein the drain opening side end of the peripheral wall surface forming the through hole of the decorative plate portion and the depression are provided. The end of the side wall surface on the washing area side is connected.

In the drain cover according to claim 2, the end on the drain side of the peripheral wall surface constituting the through hole of the decorative plate portion and the end on the washing place side of the side wall surface of the recess are connected. When a large amount of waste water suddenly flows into the drain receiving part, the air on the drain outlet side is guided to the through hole by the side wall surface of the depression and escapes to the washing place side. For this reason, it becomes more difficult for air to remain between the drain outlet side of the recess and the washing area side of the through hole.
Accordingly, it is possible to further reduce the amount of air remaining on the side of the decorative plate portion at the time of drainage.

  According to a third aspect of the present invention, there is provided the decorative cover for a drain outlet according to the first aspect or the second aspect, wherein a plurality of the depressions are formed in the decorative plate portion together with the through-holes, and are adjacent to each other. The end portions on the side of the drainage side of the side walls of the recesses that fit are connected to each other.

  In the decorative cover for the drain port according to claim 3, since the end portions on the drain port side of the side wall surfaces of the recesses adjacent to each other are connected to each other, most of the decorative plate portion on the drain port side becomes a recess, For example, compared with the case where the end portions on the drainage side of the side wall surfaces of the recesses adjacent to each other are not connected to each other (for example, the end portions are connected to each other via a horizontal plane), Is less likely to remain.

  The decorative cover for a drain according to claim 4 is the decorative cover for a drain according to claim 1 or 2, wherein the through hole is a long hole, and the decorative plate portion has the long hole. A plurality of the recesses are formed at least along the width direction of the long hole, and the recesses are convex toward the drainage port from the bottom of the recess between the recesses adjacent to each other in the width direction, and in the longitudinal direction of the long hole. Extending ridges are formed.

  In the decorative cover for a drain outlet according to claim 4, a plurality of depressions are formed in the decorative plate portion along with the long holes along at least the width direction of the long holes, and the depressions are formed between the depressions adjacent to each other in the width direction. A protrusion that protrudes toward the drainage port from the bottom of the tube and extends in the longitudinal direction of the long hole is formed. By this protrusion, the decorative board portion can secure the bending rigidity in the longitudinal direction while reducing the resin material by forming the recess.

  The drain opening decorative cover according to claim 5 is the drain covering decorative cover according to claim 4, wherein the drain opening side ends of the side wall surfaces of the recesses adjacent to each other in the width direction are connected to each other. ing.

  In the drain cover according to claim 5, since the end portions on the drain port side of the side walls of the recesses adjacent to each other in the width direction of the long hole are connected to each other, The veneer is mostly a depression, for example, a decorative board part as compared to one in which the end parts on the side of the side wall of the depressions adjacent to each other are not connected to each other (for example, the ends are connected to each other via a horizontal plane) Air is less likely to remain on the drain outlet side.

  Further, the protrusions formed between the recesses adjacent to each other in the width direction of the long hole are convex toward the drain port side, and both wall surfaces in the width direction of the long holes are side walls of the recesses adjacent to each other in the width direction. Therefore, the wastewater adhering to both wall surfaces easily flows down to the drainage port side along the wall surfaces. For this reason, the draining property of the decorative cover for the drain outlet is improved.

  The drain cover for the drain port according to claim 6 is the decorative cover for the drain port according to claim 4 or 5, wherein the drain plate side of the decorative plate portion is along the width direction of the long hole. Only one rib extending in a straight line and projecting toward the drain port is formed.

  In the decorative cover for a drain outlet according to claim 6, the rib is formed on the decorative plate portion and has a rib that extends linearly along the width direction of the long hole and protrudes toward the drain port. Only books are formed. In the decorative plate portion, the bending rigidity in the longitudinal direction of the long hole is secured by the protrusion, and the bending rigidity in the width direction is secured by the rib. Thereby, it is suppressed that the decorative cover for drain outlets is plastically deformed by the external force from the washroom side, for example.

  In addition, when two or more ribs are formed on the decorative plate portion, there is a possibility that air may easily remain between the ribs. However, by using only one rib on the decorative plate portion, as described above, It is possible to suppress plastic deformation of the decorative cover for the drain outlet while preventing residual air.

  As described above, according to the decorative cover for a drain outlet of the present invention, it is possible to suppress the lifting during drainage while ensuring the drainage flow rate and to improve the cleanability.

As shown in FIG. 5, the end portion 12 </ b> C on the drainage port 98 side of the peripheral wall surface forming the through hole 16 of the decorative plate portion 12 is the end of the side wall surface 20 forming the recess 18 of the decorative plate portion 12 on the washing place 92 side. It is connected to the part 20A. That is, the peripheral wall surface constituting the through hole 16 and the side wall surface 20 constituting the recess 18 intersect at the position of the end portion 12C (or the end portion 20A), and the peripheral wall surface of the through hole 16 and the side wall surface 20 are. It is continuous.
Further, the end portion 12C is connected to the end portion 22A on the side of the washing place 92 of the side wall surface 22 constituting the recess 18. That is, the peripheral wall surface constituting the through hole 16 and the side wall surface 22 constituting the recess 18 intersect at the position of the end portion 12C (or the end portion 22A), and the peripheral wall surface of the through hole 16 and the side wall surface 22 are formed. It is continuous.

On the other hand, the decorative plate portion 12 is formed with a protrusion 26 that protrudes toward the drainage port 98 from the bottom of the recess 18 and extends in the longitudinal direction X between the recesses 18 adjacent to each other in the width direction Y. ing. The protrusion 26 has a substantially triangular cross-sectional shape, and both side wall surfaces are constituted by the side wall surfaces 22 of the recesses 18 adjacent to each other in the width direction Y.
Moreover, the edge part by the side of the drain port 98 of the side wall surface 22 of the hollow 18 mutually adjacent in the said width direction Y is connected.

Here, as shown in FIG. 3 and FIG. 4, a plurality of the protrusions 28 are formed along the width direction Y to constitute one continuous protrusion 29.

  Further, the decorative lid 10 of the present embodiment is an integrally molded product of resin. That is, the decorative board part 12 and the leg part 14 are integrally formed. In addition, as a resin material which forms the decorative cover 10, you may use what mixed the glass fiber in the polypropylene etc., for example.

Next, the effect of the decorative cover 10 of 1st Embodiment is demonstrated.
As shown in FIG. 3, in the decorative lid 10, the decorative plate portion 12 is formed with a through hole 16 that communicates the drain port 98 side and the washing place 92 side. For this reason, the drainage of the washing place 92 flows to the drainage port 98 through the clearance between the drainage receiving portion 96 and the decorative plate portion 12 and the through hole 16. For example, the through hole 16 of the present embodiment is formed in the decorative plate portion 12. Compared to those that are not performed, it is possible to secure a drainage flow rate from the washing place 92 to the drainage port 98.

  In the case of the decorative lid 10, when a large amount of waste water suddenly flows into the drain receiving portion 96 and overflows from the drain receiving portion 96, the air on the drain outlet 98 side passes through the through holes 16 of the decorative plate portion 12. For example, the amount of air remaining on the drainage port 98 side of the decorative plate portion 12 can be reduced as compared with the case where the through hole 16 is not formed in the decorative plate portion 12. It is possible to suppress the lifting from.

In particular, in the decorative lid 10, since the side wall surfaces 20 and 22 of the recess 18 are inclined toward the through hole 16 so as to reduce the plate thickness of the decorative plate portion 12, a large amount of drainage is suddenly generated as described above. Flows into the drainage receiving portion 96, the air on the drainage port 98 side is guided by the side wall surfaces 20 and 22 of the recess 18 and sent to the bottom side of the recess 18, and the through-hole 16 that opens to the bottom of the recess 18 is provided. Pass through to the washing station 92 side. That is, the depression 18 makes it difficult for air to remain on the drain outlet side of the decorative plate portion 12.
Accordingly, the amount of air remaining on the side of the drainage port 98 of the decorative plate portion 12 during drainage can be further reduced, and lifting from the drainage receiving portion 96 can be effectively suppressed.

  Further, in the decorative lid 10, the side wall surfaces 20 and 22 of the recess 18 are inclined toward the through hole 16 so as to reduce the plate thickness of the decorative plate portion 12. Compared with what 22 extends along the thickness direction T of the decorative board part 12, it becomes easy to put a cleaning tool etc. in a hollow, and cleaning work becomes easy (cleanability improves).

  Therefore, according to the decorative lid 10, it is possible to suppress the lifting during drainage while ensuring the drainage flow rate, and to improve the cleaning performance.

In the decorative lid 10, the end portion 12 </ b> C of the peripheral wall surface that forms the through hole 16 of the decorative plate portion 12, the end portion 20 </ b> A of the side wall surface 20 that forms the recess 18 of the decorative plate portion 12, and the end portion 12 </ b> C and the decorative plate portion. Since the end portion 22A of the side wall 22 constituting the twelve depressions 18 is connected, when a large amount of waste water suddenly flows into the drain receiving portion 96, the air on the drain outlet 98 side is on the side of the depression 18 The walls 20 and 22 are directly guided to the through hole 16 and exit to the washing place 92 side. That is, a portion where air can remain is not formed between the drain port 98 side of the recess 18 and the washing place 92 side of the through-hole 16, so that it is difficult for air to remain on the drain port 98 side of the decorative plate portion 12.
Accordingly, it is possible to further reduce the amount of air remaining on the drainage port 98 side of the decorative plate portion 12 during drainage.

  Further, in the decorative lid 10, the end portions of the side wall surfaces 22 of the recesses 18 adjacent to each other in the width direction Y are connected to each other, and the drain ports of the side wall surfaces 20 of the recesses 18 adjacent to each other in the longitudinal direction X are connected. Since the end portions on the 98 side are connected to each other, most of the back surface 12B side (the drain port 98 side) of the decorative plate portion 12 becomes the recess 18, for example, the drain port side of the side wall surface of the recess 18 adjacent to each other. Compared with the case where the end portions of the decorative plate portion 12 are not connected to each other, air hardly remains on the drainage port 98 side of the decorative plate portion 12.

  Since the recess 18 is formed in the decorative cover 10 on the drainage port 98 side of the decorative cover part 12, the resin material is reduced without reducing the beauty of the washing area 92 of the decorative cover part 12, thereby reducing the weight and cost. Can be achieved. And, since the plurality of ridges 26 and one ridge 29 are formed on the decorative plate portion 12 by the depressions 18, the bending rigidity in the longitudinal direction X is secured by the plurality of ridges 26, and The bending stiffness in the width direction Y is ensured by the protrusions 29. Thus, by ensuring the rigidity of the decorative board part 12, even if an external force acts on the decorative board part 12 from the washing place 92 side, plastic deformation of the decorative board part 12 and the like are suppressed. Therefore, the durability of the decorative lid 10 is improved.

Further, the protrusion 26 is convex downward, and both side wall surfaces in the width direction Y are constituted by the side wall surfaces 22 of the recesses 18 adjacent to each other, so that the waste water adhering to both side wall surfaces travels along the side wall surfaces. It tends to flow down to the drain port 98 side (downward).
Similarly, the protrusion 28 protrudes downward, and both side wall surfaces in the longitudinal direction X are constituted by the side wall surfaces 20 of the recesses 18 adjacent to each other, so that wastewater adhering to both side wall surfaces travels along the side wall surfaces. It tends to flow down to the drain port 98 side (downward).
Thereby, the draining property of the decorative lid 10 is improved.

Further, a protrusion 44 is formed which protrudes from the bottom of the recess 18 toward the drainage port 98 (in the protruding direction of the leg portion 14) and extends in the width direction Y with respect to the longitudinal direction X. The protrusion 44 has a substantially trapezoidal cross-sectional shape, and the inclined wall surfaces on both sides are constituted by the side wall surfaces 20 of the recesses 18 adjacent to each other in the longitudinal direction X. Here, as shown in FIG. 6, a plurality of the protrusions 44 are formed along the width direction Y to form a single continuous protrusion 45.

On the back surface 12B side (drainage port 98 side) of the decorative plate portion 12, only one rib 46 that extends linearly along the width direction Y and protrudes in the protruding direction of the leg portion 14 is formed. Specifically, as shown in FIG. 6, the rib 46 extends along the lower surface (top surface) of the single protrusion 45, and both leg portions are located on the center line L <b> 1 of the decorative plate portion 12. 14 respectively.
In addition, the rib 46 of this embodiment is also integrally formed with the decorative board part 12 and the leg part 14. FIG.
