Description

  The present invention relates to a bathtub provided with a bath lid.

It has been conventionally known that a user can relax by taking a bathing posture in which the rim of the bathtub is used as a pillow while being used in the bathtub. However, the height of the bathtub is relatively low so that it is easy to straddle when taking a bath from the washroom, so it is difficult to put the head on the rim of the bathtub unless the waist is thrown forward.
Therefore, it is possible to consider a bathtub where the rim of the bathtub rim is not changed in height, and the rim is raised one step only at the position where the head comes, but this creates a step on the bathtub rim, so it looks good There was no problem.
On the other hand, as shown in patent document 1, the bathtub which formed the concave curved surface in the longitudinal direction at the rim of the bathtub is proposed. In this example, the rim at the position where the head hits can be raised with the straddle height secured, and the rim has no stepped part and the upper surface is drawn with a curved surface, so it looks beautiful. felt.

Japanese Patent Laid-Open No. 10-323295

However, in order to seal the upper surface of the bathtub having a curved upper surface as described above, a large gap is formed in the conventional flat-shaped bath lid, and therefore, as shown in FIGS. I had to use an expression bath lid. However, the roll-up bath lid cannot store the wound bath lid, and is often placed on the rim of the bathtub, so it is easy to get dirty, but on the other hand, it winds up on the surface of the roll-up bath lid. Therefore, it was difficult to remove dirt and the cleaning property was extremely poor.
Then, an object of this invention is to provide the bathtub provided with the bath lid which can seal the bathtub which has a concave curved surface on the upper surface using the plate-shaped bath lid excellent in cleaning property.

In order to achieve the above-described object, the invention according to claim 1 of the present invention includes a bathtub main body having a rectangular shape in plan view, which is installed adjacent to a bathroom washroom and has a rim formed around the upper part thereof, and the bathtub In the bathtub provided with a bath lid that seals the upper surface of the main body, the bathtub main body is the same as the washing-room-side rim closest to the washing place so that the upper surface of the washing-room-side rim is concave with respect to the longitudinal direction. of it by bending with a curvature, and the farthest back wall side Trim from the washing space, it upper surface of said back wall side rim be curved in the same curvature so as to be concave with respect to the longitudinal direction, The bath lid has a plate shape capable of covering the upper surface of the bathtub with a plurality of the bath lids, and the entire bath lid is curved with the same curvature as the concave curved surface of the bathtub.

According to this, since the rim of the bathtub body has a curved surface with the same curvature from end to end, the quadrangle is the basic bathroom, and the bathtub body has a rounded appearance. Can give a feeling.
Moreover, since the bath lid is provided with a curved surface that coincides with the rim of the bathtub body, the bath top can be sealed with the bath lid, and heat insulation efficiency similar to that of a general bathtub body can be maintained.
Furthermore, the bathtub-side surface of the bath lid is a curved surface having the same curvature as the curved surface of the rim of the bathtub body. Therefore, even if the position of the bath lid is displaced, there is no gap between the bath body. Therefore, extremely high heat insulation efficiency can be obtained.

  In the invention according to claim 2, the short side rim of the bathtub main body connecting the wash rim and the back wall rim is the same in the same direction as the wash rim and the back wall rim. Curved with curvature.

  According to this, since the short side rim of the bathtub body is a curved surface formed so as to be inclined to the inside of the bathtub body at a position higher than the position of the rim of the conventional bathtub body, the conventional bathtub is provided. Compared to the main body, it is possible to support the head of a person in a bathing posture with a comfortable posture, and it becomes possible to relax more when taking a bath.

  ADVANTAGE OF THE INVENTION According to this invention, the bathtub provided with the bath lid which can seal the bathtub which has a concave curved surface on the upper surface using the plate-shaped bath lid excellent in cleaning property is provided.

The perspective view of the bathroom which comprised the bathtub of this invention Perspective view of the bathtub body It is a figure showing a bath lid, (a) is a plan view, (b) is a sectional view A perspective view of the bathtub body with a bath lid

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a bathroom provided with the bathtub of the present invention, and FIG. 2 is a perspective view of the bathtub body.
As shown in FIG. 1, the bathtub body 2 is installed inside the bathroom 1 so as to be adjacent to the washing place 11, and a bath apron 28 is installed at the boundary with the washing place 11.

  The bathtub body 2 has a rectangular shape in plan view, and includes a bottom surface 21, an inner side surface 22 that is closest to the washing area, an inner side surface 23 that is farthest from the washing area 11 and faces the inner side surface 22, and a backrest. A left inner side surface 24 for back and a right inner side surface 25 for backrest are provided, and the upper surface is an opening 26. Further, rims formed so as to protrude outward are provided at the upper ends of the wash-place-side inner surface 22, the back wall-side inner surface 23, the backrest left-side inner surface 24, and the backrest right-side inner surface 25. This rim is formed continuously around the four circumferences of the bathtub body 2.

  Moreover, the bathtub main body 2 is provided with a drain plug (not shown) having a drain outlet 211 formed on the bottom surface thereof and capable of closing the drain outlet 211 so that hot water can be stored in the bathtub main body 2.

  The bathtub body 2 is preferably surrounded by a heat insulating material (not shown) in order to make it difficult for the stored hot water to escape.

  Moreover, this bathtub main body 2 is making the washing-room side inner surface 22 incline rather than the back wall side inner surface 23. FIG. Thereby, the inner surface corner portion 26 on the side close to the washing place 11 of the bathtub body 2 has a larger curvature R than the inner surface corner portion 27 on the back wall side away from the washing place 11. Therefore, the inner surface corner portion 26 on the side close to the washing place 11 can be used as a backrest. By using the inner corner portion 26 as a backrest, a space for extending a leg in a bathing posture can be secured, so even a person with a long leg can relax more.

Next, the shape of the rim of the bathtub body will be described.
The washing place side rim 22a formed outside the washing place side inner side surface 22 of the bathtub body 2 and the back wall side rim 23a formed outside the back wall side inner side face 23 have an upper surface formed of the rim 22a, The curved surface is recessed downward along the longitudinal direction of 23a. The curvature is the same from end to end, and in this embodiment, the curvature is R4000 to R5000. The left rim 24a formed outside the left inner side surface 24 for the backrest and the right rim 25a formed outside the right inner surface 25 for the backrest have upper surfaces that are short of the rims 24a and 25a. A concave curved surface is formed along the direction and with the same curvature as the curved surfaces in the longitudinal direction of the wash rim 22a and the back wall rim 23a. Therefore, the upper surfaces of the rims 22a to 25a of the bathtub body 2 are curved surfaces having the same curvature from end to end in the longitudinal direction of the rectangle.

  As described above, the rims 22a to 25a of the bathtub body 2 are curved surfaces having the same curvature from end to end, so that the bathtub body 2 has a rounded appearance in the basic bathroom 1 having a quadrangular shape. Therefore, it becomes a novel form that can give a soft feeling in the bathroom 1.

  Further, the left rim 24a and the right rim 25a are higher than the position of the conventional rim and are curved surfaces formed so as to be inclined inward of the bathtub body 2. Therefore, the person's head in the bathing posture can be supported in a more comfortable posture than the conventional bathtub body. Therefore, it becomes possible to relax at the time of bathing than before.

  Moreover, while the left rim 24a and the right rim 25a are at a higher position than before, the heights of the central portions in the longitudinal direction of the washing rim 22a and the back wall rim 23a should be kept at the same height as before. Therefore, the straddle height of the bathtub body 2 can be made as usual.

Next, a bath lid that covers the bathtub body will be described.
FIG. 3 is a plan view and a cross-sectional view of the bath lid, and FIG. 4 is a perspective view of a state where the bath lid is placed on the bathtub body.

  The bath lid 3 is divided into a left lid 31 provided on the left side when viewed from the washing place 11 and a right lid 32 provided on the right side. Since the left lid 31 and the right lid 32 are symmetrical, the left lid 31 will be described below.

  The left lid 31 is a resin molded product in which a heat insulating material such as urethane foam is built in and the surface is molded with a resin such as ABS. A handle 311 for carrying the left side lid 31 is provided at a substantially central portion of the left side lid 31. The left lid 31 has a curved shape that is recessed so that the upper surface is recessed downward. Moreover, the bathtub-side surface 31a of the left lid 31 is a curved surface having a convex bottom surface. And the curvature of the curved surface 31a of the bathtub side is the same curvature as the curved surface in the longitudinal direction of the washing field side rim 22a and the back wall side rim 23a of the bathtub main body 2 described above, and in this embodiment, the curvature of R4000 to R5000. It is.

  If the bath lid 3 does not coincide with the curved surfaces of the rims 22a and 23a of the bathtub body 2, the opening 26 of the bathtub body 2 cannot be sealed with the bath lid 3, and the heat of the stored hot water is generated in the bathroom. Because it escapes to the inside, the hot water that has been collected will drop quickly.

  However, since the bath lid 3 of the present embodiment has a curved surface that coincides with the rims 22a to 25a of the bathtub main body 2, the top of the bathtub can be sealed with the bath lid 3, and is similar to a general bathtub main body. The heat insulation efficiency can be maintained.

  Furthermore, the bathtub-side surface 31 a of the bath lid 3 of the present embodiment is a curved surface having the same curvature as the curved surfaces of the rims 22 a and 23 a of the bathtub body 2. Therefore, even if the position of the bath lid 3 is shifted, no gap is generated between the bath body 2 and the bath lid 3. Therefore, extremely high heat insulation efficiency can be obtained.

The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions.
For example, in the embodiment, the curvatures of the upper surface of the bathtub body 2 and the lower surface of the bath lid 3 are both R4000 to R5000, but the present invention is not limited to this.
Further, the shorter rim (left rim 24, right rim 25) of the bathtub body 2 may be curved in the longitudinal direction of the rim with the same curvature as that of the washing rim and the rear wall rim.
