Description

The present invention relates to a bath lid.

In the bathroom, if you take a shower with the bathtub lid on, it is inevitable that the washing water splashed by your body will scatter toward the bathtub and collect on the upper surface of the bathtub lid. When the bath lid is lifted to flush the accumulated wash water to the washing place, if the bath lid tilts to the back or side even a little, the wash water will flow into the bathtub. As a countermeasure, in Patent Document 1, the wall portion on the inner side of the peripheral wall portion constituting the bathtub is made higher than the wall portion on the front side (washing area side), and when the bath lid is placed on the bathtub, the bath lid is placed. However, there is disclosed a technique for making the posture lower from the back side toward the washing place side.

Japanese Unexamined Patent Publication No. 2002-272629

If the height difference between the wall on the back side of the bathtub and the wall on the washing area side is increased, the inclination angle of the bath lid becomes large, so a high drainage effect can be expected. However, on the other hand, there is a concern that the bath lid may slip off the bathtub, so in practice, increasing the height difference between the wall on the back side and the wall on the washing area side (that is, the tilt angle of the bath lid) is not possible. difficult. If the tilt angle of the bath lid is small, a part of the washing water will remain stagnant on the upper surface of the bath lid, so it is necessary to lift the bath lid and drain the washing water to the washing place side. However, when lifting the bath lid, it is difficult to tilt the bath lid so that the washing area side is low without causing a height difference between the left and right sides because the left and right edges of the bath lid are grasped with both hands extended. Since the upper surface of the bath lid is flat, if the bath lid is tilted even slightly to the left or right, the washing water on the upper surface of the bath lid will flow into the bathtub.

The present invention has been made in view of the above-mentioned conventional circumstances, and is a problem to be solved to ensure that the water stagnant on the upper surface of the bath lid placed on the bathtub can be surely washed off to the washing place. It is supposed to be.

The first invention is
The plate-shaped lid body and the edge molding attached to the outer peripheral edge of the lid body over the entire circumference are integrated and configured, and the upper surface of the lid body functions as a water reservoir having a pair of water collecting slopes. However, it is a bath lid that can be placed in the bathtub with the water reservoir facing up.
In the state of being placed on the bathtub, in the vertical cross section in which the water reservoir is cut substantially parallel to the front wall of the bathtub facing the washing place, the pair of water collecting slopes are formed from both ends in the width direction of the front wall. It is characterized by being inclined so as to be lowered toward the center side.
The second invention is
A bath lid that has a water reservoir with a pair of water collecting slopes and can be placed on a bathtub with the water reservoir facing up.
In the state of being placed on the bathtub, in the vertical cross section in which the water reservoir is cut substantially parallel to the front wall of the bathtub facing the washing place, the pair of water collecting slopes are formed from both ends in the width direction of the front wall. It is inclined so that it becomes lower toward the center,
An edge molding is provided on the side edge of the outer peripheral edge of the water reservoir extending in the direction intersecting the front wall.
It is characterized in that the water collecting slope is formed so as to be in contact with the edge molding or close to the edge molding.

According to the first invention and the second invention, the wash water scattered on the water reservoir portion of the bath lid collects in the widthwise central portion of the water collection portion due to the gradient of the water collection slope. When flushing the washing water collected in the water reservoir to the washing place, the bath lid may be lifted and tilted so that the washing place side is lowered. Even if the bathtub tilts to the left or right when the bathtub lid is lifted, the wash water collected in the center of the width direction of the reservoir flows up the water collecting slope and flows into the bathtub from the side edge of the bathtub lid. There is no fear. According to the second invention, when the catchment slope is formed so as to be in contact with the edge molding, there is no possibility that the wash water remains in the region along the side edge of the reservoir portion. Further, when the catchment slope is formed so as to be close to the edge molding, even if there is a slight horizontal plane in the area between the catchment slope and the edge molding, the water remaining on the horizontal plane is on the catchment slope. There is no risk of water remaining in the horizontal region along the edge molding as it is drawn into the water slope by the surface tension of the water present in. Therefore, when the bath lid is lifted in an inclined posture to the left or right, it is possible to reliably prevent the washing water that has stagnated at the side edge of the water reservoir from flowing into the bathtub. In addition, even if the water remaining on a slight horizontal plane between the catching slope and the edge molding is not drawn into the catching slope by the surface tension of the water on the catching slope, the amount of water remaining on the horizontal plane is It is very small, and it is not enough to get over the edge molding when the bath lid is lifted in a tilted position to the left and right.

In the present invention, in the innermost region of the peripheral edge of the water reservoir along the innermost edge far from the washing place, the inner side inclined surface inclined so as to be lower from the innermost edge side toward the washing place side. May be formed. According to this configuration, the wash water scattered in the inner region of the water reservoir is collected in the central portion of the water reservoir due to the gradient of the inner inclined surface. Even if the bathtub is tilted so that the back side is lowered when the bath lid is lifted, the washing water collected in the center of the water reservoir goes up the back slope surface and enters the bathtub from the back edge of the bathtub. There is no risk of flowing into.

In the present invention, in the peripheral portion of the peripheral portion of the water reservoir, the washing place side region along the front edge near the washing place may be formed with a washing place side inclined surface inclined so as to become lower as the distance from the washing place increases. .. According to this configuration, the wash water scattered in the washing area on the washing place side of the water collecting part collects in the central part of the water collecting part due to the gradient of the inclined surface on the washing place side. Even if the bathtub is tilted so that the washing area side is lowered when the bath lid is lifted, the washing water collected in the center of the water reservoir goes up the inclined surface on the washing area side and enters the bathtub from the front edge of the bathtub. There is no risk of flowing in.

<Example 1>
Hereinafter, Example 1 embodying the present invention will be described with reference to FIGS. 1 to 3. In the following description, the front-back direction is defined as the lower side in FIG. 1 and the right side in FIG. 3 as the front side. Regarding the vertical direction, the directions appearing in FIGS. 2 and 3 are defined as upward and downward as they are. Regarding the left and right directions, the directions appearing in FIGS. 1 and 2 are defined as left and right as they are.

As shown in FIGS. 1 and 3, the bathroom 10 has a bathtub 11 arranged in the posterior region of the bathroom 10 and a washing area 12 arranged in the front region of the bathroom 10. A pair of symmetrical bath lids 14 are placed on the bathtub 11. By placing the pair of bath lids 14 on the bathtub 11, the upper surface opening 13 of the bathtub 11 is closed. Since the bath lid 14 has a symmetrical shape, the one placed on the left side region of the bathtub 11 will be described, and the detailed description of the bath lid 14 placed on the right side will be omitted.

The plan view shape of the bath lid 14 is a pentagon in which one of the four rectangular corners (front left) is diagonally chamfered. The bath lid 14 is a combination of a plate-shaped lid main body 15 and an edge molding 16 attached to the outer peripheral edge of the lid main body 15 over the entire circumference. The upper surface of the lid main body 15 in a state where the bath lid 14 is placed on the bathtub 11 functions as a water reservoir 17 for receiving the washing water (not shown) scattered from the washing place 12 side. The water reservoir 17 is composed of one water collecting surface 18, a pair of left and right water collecting slopes 19L and 19R, one washing place side inclined surface 20, and one back side inclined surface 21.

The water collecting surface 18 is a flat surface in which the bath lid 14 is placed on the bathtub 11 and is horizontal. The plan view shape of the water collecting surface 18 is a substantially rectangular shape with four sides oriented in the front-rear direction or the left-right direction. The water collecting surface 18 is arranged in the substantially central portion of the bath lid 14 (lid body 15) in the front-rear direction. Specifically, the center of the water collecting surface 18 in the front-rear direction is located slightly behind the center of the bath lid 14 in the front-rear direction (direction away from the washing place 12). The water collecting surface 18 is arranged at the center of the bath lid 14 in the left-right direction. Specifically, the center of the water collecting surface 18 in the left-right direction is located at the center of the bath lid 14 in the left-right direction.

FIG. 2 is a vertical cross-sectional view (normal cross-sectional view) of the bathtub 11 in which the bath lid 14 (reservoir portion 17) is cut substantially parallel to the front wall 11F facing the washing place 12. As shown in FIG. 2, the water collecting slope 19L on the left side gradually becomes lower from the left edge of the outer peripheral edge of the lid body 15 toward the right side (water collecting surface 18 located at the center of the bath lid 14). It consists of an inclined plane. As shown in FIG. 1, the plan view shape of the water collecting slope 19L on the left side is approximately a trapezoid with the two opposite sides (upper base and lower base) facing in the front-rear direction, and in detail, one of the front ends of the trapezoid. The shape is such that the part is cut out diagonally. The left end edge portion (upper end edge portion) of the water collecting slope 19L on the left side is in contact with the edge molding 16 over the entire area thereof. Therefore, there is no horizontal flat area where wash water collects between the edge molding 16 and the left edge of the water collecting slope 19L on the left side.

As shown in FIG. 2, the water collecting slope 19R on the right side gradually becomes lower from the right edge of the outer peripheral edge of the lid body 15 toward the left (water collecting surface 18), contrary to the water collecting slope 19L on the left side. It consists of a plane inclined like this. The inclination angle of the water collecting slope 19R on the right side with respect to the water collecting surface 18 is the same as the inclination angle of the water collecting slope 19L on the left side. As shown in FIG. 1, the plan view shape of the water collecting slope 19R on the right side is a trapezoid with two opposite sides (upper bottom and lower bottom) facing in the front-rear direction. The right end edge portion (upper end edge portion) of the water collecting slope 19R on the right side is in contact with the edge molding 16 over the entire area thereof. Therefore, there is no horizontal flat area where wash water collects between the edge molding 16 and the right end edge of the water collecting slope 19R on the right side.

FIG. 3 is a vertical cross-sectional view (normal cross-sectional view) in which the bath lid 14 (reservoir portion 17) is cut at a substantially right angle to the front wall 11F of the bathtub 11. As shown in FIG. 3, the washing place side inclined surface 20 is formed in the washing place side region along the front end edge close to the washing place 12 in the peripheral portion of the water reservoir portion 17. The washing place side inclined surface 20 is formed of a plane inclined so as to gradually decrease from the front edge to the rear (water collecting surface 18) of the outer peripheral edge of the lid main body 15. As shown in FIG. 1, the plan view shape of the inclined surface 20 on the washing place side is substantially a trapezoid with the two opposite sides (upper base and lower bottom) oriented in the left-right direction, and in detail, a part of the left end portion of the trapezoid. It is a shape that is cut out diagonally. The leading edge portion (upper end edge portion) of the washing place side inclined surface 20 is in contact with the edge molding 16 over the entire area thereof. Therefore, there is no horizontal flat area where washing water collects between the edge molding 16 and the front edge of the washing place side inclined surface 20.

As shown in FIG. 3, an inner inclined surface 21 is formed in the inner region of the peripheral edge of the water reservoir 17 along the rear end edge far from the washing place 12. Contrary to the washing place side inclined surface 20, the back side inclined surface 21 is formed of a plane inclined so as to be gradually lowered from the trailing edge toward the front (water collecting surface 18) of the outer peripheral edge of the lid main body 15. The inclination angle of the back inclined surface 21 with respect to the water collecting surface 18 is an angle larger than the inclination angle of the washing place side inclined surface 20. Further, the front-rear dimension of the back-side inclined surface 21 is smaller than the front-rear dimension of the washing place-side inclined surface 20. As shown in FIG. 1, the plan view shape of the back inclined surface 21 is a trapezoid with two opposite sides (upper base and lower bottom) oriented in the left-right direction. The trailing edge portion (upper end edge portion) of the back inclined surface 21 is in contact with the edge molding 16 over the entire area thereof. Therefore, there is no horizontal flat area where wash water collects between the edge molding 16 and the trailing edge of the back inclined surface 21.

When the bathtub 14 is placed on the bathtub 11 and the shower is taken in a standing position at the washing place 12, the washing water splashed by the body is scattered toward the bathtub 11 and is placed on the upper surface (reservoir portion 17) of the bathtub 14. Accumulate. The wash water scattered on the water collecting slopes 19L and 19R of the water collecting portion 17 flows down to the center side in the left-right direction of the bath lid 14 due to the gradient of the water collecting slopes 19L and 19R and reaches the water collecting surface 18. The washing water scattered on the washing place side inclined surface 20 flows onto the water collecting surface 18 due to the slope of the washing place side inclined surface 20. The wash water scattered on the back inclined surface 21 flows onto the water collecting surface 18 due to the inclination of the back inclined surface 21. As a result, the wash water scattered on the water reservoir 17 stays on the water collecting surface 18. When the amount of the washing water scattered is large, the washing water also collects at the lower ends of the water collecting slopes 19L and 19R, the washing place side inclined surface 20 and the back side inclined surface 21.

When the washing water collects on the upper surface (reservoir portion 17) of the bath lid 14 as described above, grasp the left and right edges of the bath lid 14 with both hands and lift the bath lid 14 from the bathtub 11, and the washing place 12 side becomes lower. By tilting the bath lid 14 in this way, the washing water is drained to the washing place 12 side. At this time, since both hands holding the bath lid 14 are in an extended state, it is difficult to control the posture of the bath lid 14, and the bath lid 14 may be tilted to the left or right.

In consideration of this point, a pair of left and right water collecting slopes 19L and 19R were formed on the upper surface of the bath lid 14 of this embodiment. The water collecting slopes 19L and 19R are inclined so as to be lower from the left and right side edges of the bath lid 14 (lid body 15) toward the central portion in the left-right direction. Therefore, even if the bath lid 14 is slightly tilted to the left or right, the slopes of the water collecting slopes 19L and 19R on the lowered side are kept in a direction to be lowered toward the center side (water collecting surface 18) of the bath lid 14. Dripping. Therefore, there is no possibility that the washing water stagnant on the water collecting surface 18 will reach the side edge portion of the bath lid 14 against the gradients of the water collecting slopes 19L and 19R. As a result, the washing water is prevented from flowing into the bathtub 11 from the side edge portion of the bath lid 14.

Further, the upper surface (water collecting portion 17) of the bath lid 14 is inclined so as to be lowered from the back side of the bath lid 14 (the side opposite to the washing place 12) toward the central portion (water collecting surface 18) of the bath lid 14. The back inclined surface 21 is formed. Therefore, even if the bath lid 14 is tilted in a direction in which the back side is lowered, the slope of the back side inclined surface 21 is maintained in a direction in which the bath lid 14 is tilted toward the center side (water collecting surface 18). Therefore, there is no possibility that the washing water stagnant on the water collecting surface 18 reaches the trailing edge portion (back end portion) of the bath lid 14 against the gradient of the back inclined surface 21. This prevents the washing water from flowing into the bathtub 11 from the inner end of the bath lid 14.

The bath lid 14 of this embodiment has a water reservoir 17 in which a pair of left and right water collecting slopes 19L and 19R are formed, and can be placed on the bathtub 11 with the water collecting portion 17 facing upward. be. In the state where the bath lid 14 is placed on the bathtub 11, a pair of left and right water collecting slopes 19L and 19R are formed in a vertical cross section in which the water reservoir 17 is cut substantially parallel to the front wall 11F facing the washing place 12 in the bathtub 11. , The front wall 11F is inclined so as to be lower from both end sides in the width direction (left-right direction) toward the center side.

The wash water scattered on the water collecting part 17 of the bath lid 14 collects in the central part in the width direction (water collecting surface 18) of the water collecting part 17 due to the gradients of the water collecting slopes 19L and 19R. When the washing water collected in the water reservoir 17 is flushed down to the washing place 12, the bath lid 14 may be lifted and tilted so that the washing place 12 side is lowered. Even if the bath lid 14 is tilted to the left or right when the bath lid 14 is lifted, the washing water collected in the widthwise central portion (water collecting surface 18) of the water collecting portion 17 goes back to the water collecting slopes 19L and 19R. There is no possibility that the water will flow into the bathtub 11 from the side edge of the bath lid 14.

Edge moldings 16 are provided on both left and right edges of the outer peripheral edge of the water reservoir 17 extending in a direction intersecting the front wall 11F, and the upper end edges of the catchment slopes 19L and 19R are edge moldings 16. It is formed so as to be in contact with. According to this configuration, since there is no horizontal region in which the washing water remains in the region along the left and right side edges of the water reservoir 17, when the bath lid 14 is lifted in an inclined posture to the left and right. It is possible to reliably prevent the washing water that has stagnated on the side edge of the water reservoir 17 from flowing into the bathtub 11.

Further, in the inner region of the peripheral edge of the water reservoir 17 along the inner edge (rear end edge) far from the washing place 12, the inner side inclined so as to be lower from the inner end edge side toward the washing place 12 side. The inclined surface 21 is formed. According to this configuration, the wash water scattered in the inner region of the water reservoir 17 collects in the central portion of the water reservoir 17 due to the gradient of the inner inclined surface 21. Even if the bath lid 14 is tilted so that the back side is lowered when the bath lid 14 is lifted, the washing water collected in the central part of the water reservoir 17 traces back to the back slope surface 21 to the back of the bath lid 14. There is no risk of flowing into the bathtub 11 from the edge.

Further, in the washing place side region along the front end edge close to the washing place 12 in the peripheral portion of the water reservoir portion 17, the washing place side inclined surface 20 inclined so as to become lower as the distance from the washing place 12 to the rear is formed is formed. According to this configuration, the washing water scattered in the washing area on the washing place side of the water collecting part 17 collects in the central part of the water collecting part 17 due to the gradient of the inclined surface 20 on the washing place side. Even if the bath lid 14 is tilted so that the washing area 12 side is lowered when the bath lid 14 is lifted, the washing water collected in the central portion of the water reservoir 17 traces back to the washing area side inclined surface 20 of the bath lid 14. There is no risk of flowing into the bathtub 11 from the front edge.
