The bowl portion 10 is integrally formed by continuously surrounding the bottom pot surface portion 14 with the front pot surface portion 11, the left and right pot surface portions 12, and the rear pot surface portions 13. In the bowl portion 10, a drain port 15 is formed at a position near the rear portion of the central portion in the left-right direction of the bottom pot surface portion 14. The drain port 15 is formed so as to penetrate the bottom pot surface portion 14 in the vertical direction. The drain port 15 is formed at the lowest position of the bottom pot surface portion 14. An overflow flow path 42 communicating with an overflow hole 41 described later in the overflow portion 40 communicates with the drain port 15. The bowl portion 10 has a bowl shape that decreases from the pot surface portions 11, 12, and 13 toward the drain port 15 of the bottom pot surface portion 14.

As shown in FIG. 2, the front pot surface portion 11 is formed so that the upper end thereof extends substantially horizontally in the left-right direction. As shown in FIGS. 3 and 6, the position of the upper end of the front pot surface portion 11 is the lowest as compared with the other pot surface portions 12 and 13. As shown in FIG. 4, the front pot surface portion 11 is provided at a position farthest from the position of the drain port 15 in a plan view as compared with the other pot surface portions 12 and 13. The inner surface 10A of the bowl portion 10 has the gentlest inclination as a whole from the drain port 15 of the bottom pot surface portion 14 toward the front pot surface portion 11. As shown in FIG. 6, the inner surface 10A of the bowl portion 10 in the front pot surface portion 11 is formed by a gently curved surface that is convex upward. The edge 11A of the front pot surface portion 11 is formed by a curved surface protruding forward. In other words, the edge 11A has an R shape protruding forward. The edge 11A of the front pot surface portion 11 is also the front end of the basin 1. The height from the upper surface M of the counter 101A to the edge 11A is about 35 mm.

The left and right pot surface portions 12 have a substantially symmetrical shape. As shown in FIGS. 3 and 6, each pot surface portion 12 is formed so that the position of the upper end thereof is lowered while being gently curved from the rear end to the front end. The inner surface 10A of the bowl portion 10 of the pot surface portion 12 is formed by a gently curved surface that becomes concave diagonally downward. The edge 12A of the pot surface portion 12 is formed by a curved surface protruding upward.

As shown in FIG. 2, the rear pot surface portion 13 is formed at a position higher than the upper ends of the front pot surface portion 11 and the pot surface portion 12 and has an upper end extending substantially horizontally in the left-right direction. As shown in FIG. 4, the rear pot surface portion 13 is provided at a position closest to the position of the drain port 15 in a plan view as compared with the other pot surface portions 11 and 12. Therefore, the inner surface 10A of the bowl portion 10 has the steepest slope as a whole from the drain port 15 of the bottom pot surface portion 14 toward the rear pot surface portion 13. Specifically, as shown in FIG. 6, the inner surface 10A of the bowl portion 10 in the rear pot surface portion 13 has a flat shape that rises diagonally upward at an inclination close to vertical in most of the lower end side, and has a substantially cross section at the upper end portion. It has a convex curved surface in the shape of a quarter arc. The edge 13A of the rear pot surface portion 13 has a flat surface shape extending in the vertical direction. Below the edge 13A, a rear wall portion 13B forming a hollow portion 16 described later extends continuously. The rear wall portion 13B is connected to the outer surface 10B of the bowl portion 10 on the rear pot surface portion 13 to form the hollow portion 16.

As shown in FIGS. 6 and 7, the front supported portion 20 is provided in a row below the front pot surface portion 11 of the bowl portion 10, and constitutes the peripheral edge portion of the washbasin 1. Specifically, the front supported portion 20 is a portion below the long broken line in FIG. 7. In FIG. 7, the long broken line represents a virtual curved surface in which the outer surface 10B of the bowl portion 10 is extended forward of the bowl portion 10 so as to follow the curved surface formed by the inner surface 10A of the bowl portion 10. The front end of this virtual curved surface coincides with the lower end of the R-shaped surface formed by the edge 11A. In other embodiments, the virtual curve may be above or below the bottom edge of the R-shaped surface. The front supported portion 20 is integrally provided on the front pot surface portion 11 so as to be connected below the front pot surface portion 11 which is a portion above the long broken line in FIG. 7. The front supported portion 20 has an outer wall portion 21, a bottom wall portion 22, and an inner wall portion 23. The front supported portion 20 is formed so that the outer wall portion 21 and the inner wall portion 23 rise from both front and rear ends of the bottom wall portion 22 at the lower end portion.

As shown in FIG. 7, the outer wall portion 21 is formed in a curved shape having a cross-sectional shape that is convex diagonally backward and upward. It can be said that the outer wall portion 21 has a curved shape that tilts forward from the lower end portion to the upper end portion. The upper end of the outer wall portion 21 is connected to the edge 11A of the front pot surface portion 11. The lower end of the outer wall 21 is connected to the front end of the bottom wall 22. The wall surface 21A facing the front of the outer wall portion 21 is formed continuously from the lower end of the R shape formed by the edge 11A. The wall surface 21A is not only the outer surface of the front supported portion 20 but also the outer surface of the washbasin 1.

When the washbasin 1 is placed on the upper surface M of the counter 101A, the wall surface 21A has an inclination angle with respect to the upper surface M from the connection portion (upper end portion) with the edge 11A to the connection portion (lower end portion) with the bottom wall portion 22. ), It has a concave curved surface that gradually increases gradually. In other words, as shown in FIG. 7, the wall surface 21A is connected to the edge 11A when the tangent line of the curve indicating the wall surface 21A in the side cross section is T and the inclination angle of the tangent line T with respect to the upper surface M is θ. towards the inclination angle theta _U in the tangential T _U of (upper end portion) side is formed in a smaller becomes the form than the inclination angle theta _L in the tangential T _L of the connecting portion of the bottom wall portion 22 (lower end) side. The wall surface 21A is formed so that the inclination angle θ is 0 ° or more (including 0 °) and 90 ° or less (including 90 °) at any position. That is, the wall surface 21A is formed so that the inclination angle θ _{satisfies 0 ° ≤ θ U} <θ _L ≤ 90 °. The curvature of the wall surface 21A is substantially constant.

The wall surface 21A is a curved surface that inclines downward from the front end toward the rear. Specifically, as shown in FIG. 7, the wall surface 21A is formed by a curved surface continuous with the curved surface formed by the edge 11A. The wall surface 21A has a concave curved surface while the edge 11A has a convex curved surface. That is, the wall surface 21A is curved from a convex surface formed by the end edge 11A to a concave surface and is continuous with the end edge 11A. The wall surface 21A extends diagonally backward and downward from the edge 11A.

The inclination angle of the wall surface 21A of the outer wall portion 21, which is the outer surface of the front supported portion 20, is formed different from the inclination angle of the surface of the front pot surface portion 11 at the position corresponding to the front supported portion 20. That is, the inclination angle of the wall surface 21A of the outer wall portion 21 which is the outer surface of the front supported portion 20 is different from the inclination angle of the inner surface 10A of the bowl portion 10 at the position corresponding to the front pot surface portion 11. As described above, the washbasin 1 is made of earthenware formed by casting. In general casting molding, mud is injected into a mold and allowed to elapse for a predetermined time to attach the mud component contained in the mud to the surface of the mold to form a wall having a desired wall thickness. At this time, the mud remains uncured away from the mold surface. By discharging the uncured mud in this portion, a hollow portion can be formed, and a wall having a predetermined thickness can be formed around the portion to be the hollow portion in a desired shape. Since the wash basin 1 is made of earthenware by casting, the shape of the front pot surface portion 11 and the shape of the outer wall portion 21 do not depend on each other, and each of them is formed in a desired shape.

As shown in FIG. 7, the bottom wall portion 22 is formed so as to extend rearward continuously to the lower end portion of the outer wall portion 21. The front supported portion 20 is placed on the upper surface M of the counter 101A, which is a supporting surface, on the bottom wall portion 22. The bottom wall portion 22 has an outer contact surface 22A, an inner contact surface 22B, and a groove-shaped portion 22C. The outer contact surface 22A and the inner contact surface 22B are surfaces that come into contact with the support surface when the basin 1 is placed on the pedestal. The outer contact surface 22A is formed so as to extend rearward continuously to the lower end of the wall surface 21A. The inner contact surface 22B is formed at a position separated rearward (inward direction) from the outer contact surface 22A. The inner contact surface 22B is formed on the same virtual plane as the outer contact surface 22A. The groove-shaped portion 22C is formed in a groove shape in which the surface between the outer contact surface 22A and the inner contact surface 22B is depressed upward.

The inner wall portion 23 is continuously formed at the rear end portion of the bottom wall portion 22. The inner wall portion 23 is formed so as to extend obliquely rearward and upward from the rear end portion of the bottom wall portion 22. The upper end portion of the inner wall portion 23 is connected to the outer surface 10B of the bowl portion 10 in the front pot surface portion 11. A hollow portion 16 is formed between the front supported portion 20 and the front pot surface portion 11. The hollow portion 16 is a space formed by discharging uncured mud when the ceramic washbasin 1 is cast and molded. The hollow portion 16 is continuous between the pot surface portion 12 and the left and right supported portions 30, and below the rear pot surface portion 13 (see FIG. 6). That is, the hollow portion 16 is formed over the entire peripheral edge of the washbasin 1.

As shown in FIGS. 2 and 5, the left and right supported portions 30 are provided in a row below the left and right pot surface portions 12 of the bowl portion 10. The left and right supported portions 30 are connected to the left and right ends of the front supported portion 20 at the front end portion, and together with the front supported portion 20, form a peripheral edge portion of the washbasin 1. The rear end of each supported portion 30 extends to the rear pot surface portion 13 of the bowl portion 10. Like the front supported portion 20, each supported portion 30 includes an outer wall portion 31, a bottom wall portion 32, and an inner wall portion 33, respectively. As shown in FIG. 5, the outer wall portion 31, the bottom wall portion 32, and the inner wall portion 33 are continuous from the left and right ends of the outer wall portion 21, the bottom wall portion 22, and the inner wall portion 23 of the front supported portion 20. It is formed by extending backward.

The outer wall portion 31 is formed in a flat plate shape unlike the outer wall portion 21 of the front supported portion 20. Specifically, the outer wall portion 31 is formed so that the upper end thereof is connected to the upper end of the pot surface portion 12 and extends diagonally downward inward in a straight cross section. The left and right outer wall surfaces 31A of the outer wall portion 31 extend in a substantially planar shape continuous from the edge 12A of the pot surface portion 12. The lower end of the outer wall 31 is connected to the outer end of the bottom wall 32.

As shown in FIG. 5, the bottom wall portion 32 is formed so as to be continuous with the lower end portion of the outer wall portion 31 and extend laterally to the left and right. The supported portion 30 is placed on the upper surface M of the counter 101A, which is a supporting surface, on the bottom wall portion 32. The bottom wall portion 32 has an outer contact surface 22A, an inner contact surface 22B, and an outer contact surface 32A, an inner contact surface 32B, and a groove shape formed similarly to the grooved portion 22C of the front supported portion 20. It has a part 32C. The outer contact surface 32A, the inner contact surface 32B, and the groove-shaped portion 32C are continuous with the outer contact surface 22A, the inner contact surface 22B, and the left and right ends of the groove-shaped portion 22C of the front supported portion 20. It is formed so as to extend rearward. The outer contact surface 32A and the inner contact surface 32B are formed on the same virtual plane as the outer contact surface 22A and the inner contact surface 22B of the front supported portion 20. The outer contact surface 32A and the inner contact surface 32B, together with the outer contact surface 22A and the inner contact surface 22B, come into contact with the support surface when the basin 1 is placed on the pedestal.
The groove-shaped portion 32C is formed in a groove shape in which the surface between the outer contact surface 32A and the inner contact surface 32B is depressed upward. The groove-shaped portion 32C is formed so that the front end portion continuously extends rearward from the groove-shaped portion 22C of the front supported portion 20.

The overflow portion 40 is formed in a tubular shape extending in a substantially L-shape in a side view toward the rear of the rear pot surface portion 13 and below the bottom pot surface portion 14. The overflow portion 40 is formed with an overflow hole 41 that opens into the bowl portion 10 at the upper portion. In the overflow portion 40, the overflow flow path 42 extending from the overflow hole 41 extends to the drain port 15.

As shown in FIG. 5, the washbasin 1 has a pair of fixing portions 50. Each fixing portion 50 is provided on the left and right sides of the drain port 15 in the bottom view, and is provided at each of the positions of the left and right supported portions 30. Each fixing portion 50 has a bottom wall 51 that is recessed further upward than the height of the lower surface of the groove-shaped portion 32C of the supported portion 30. A long hole 51A long in the front-rear direction is formed in each bottom wall 51. In the wash basin 1, a fixing member for fixing the counter 101A to the elongated holes 51A is inserted from below and fixed.

The construction method of the washbasin 1 having the above configuration will be described. In the construction method of the wash basin 1, the wash basin 1 is fixed to the counter 101A as a pedestal to form the sealing processing section S.

First, the supported portions 20 and 30 of the washbasin 1 are placed on the counter 101A. Then, the washbasin 1 is fixed to the counter 101A using a fixing member (not shown). At this time, the front-rear position of the washbasin 1 is adjusted. Specifically, the position of the basin 1 is adjusted so that the rear surface of the basin 1 abuts on the front surface of the back panel 102.

Next, the sealing processing unit S is formed between the washbasin 1 and the counter 101A. The sealing processing unit S is formed for the purpose of stopping water between the washbasin 1 and the counter 101A. In forming the sealing processing portion S, a sealing material is applied between the lower portion of the wall surface 21A of the outer wall portion 21 of the front supported portion 20 on the washbasin 1 side and the upper surface M of the counter 101A. It is applied to the boundary portion between the front supported portion 20 and the counter 101A. Then, as shown in FIG. 8, a finger is inserted from the front into the space between the outer wall portion 21 and the counter 101A, and the applied sealing material is leveled to finish the surface. After that, the sealing material is cured to form the sealing processing portion S.

The sealing processing unit S is located between the lower end of the pot surface 12 and the counter 101A, between the rear end of the pot surface 12 and the front surface of the back panel 102, and between the upper end of the rear pot surface 13 and the back panel 102. It may be formed together with at least one of the front surfaces.

The operation and effect of the wash basin 1 having the above configuration and the construction method of the wash basin 1 will be described.

The wash basin 1 includes a bowl portion 10 and a front supported portion 20 as a supported portion. The bowl portion 10 has a front pot surface portion 11 formed by a curved surface whose edge 11A projects outward. The front supported portion 20 is provided so as to be connected below the front pot surface portion 11. The front supported portion 20 is placed on the upper surface M of the counter 101A as a supporting surface at the lower end portion. The wall surface 21A of the outer wall portion 21 of the front supported portion 20, which is the outer surface of the supported portion, is a concave curved surface whose inclination angle with respect to the upper surface M of the counter 101A gradually increases from the upper end portion to the lower end portion. Is formed of. With such a configuration, in the washbasin 1, the boundary portion between the wall surface 21A and the upper surface M of the counter 101A is located in front of the vanity 100, and it is difficult for the user who uses the washbasin 1 to see it. Therefore, by forming the sealing processing unit S between the wall surface 21A and the upper surface M of the counter 101A, it becomes difficult for the user of the washbasin 1 to visually recognize the sealing processing unit S. As a result, the design can be improved.

The wall surface 21A of the front supported portion 20 is formed of a concave curved surface whose inclination angle with respect to the upper surface M of the counter 101A continuously and gradually increases from the upper end portion to the lower end portion. With such a configuration, the wash basin 1 has a sufficient size such that a finger or the like is inserted between the wall surface 21A and the upper surface M of the counter 101A when forming the sealing processing portion S or during cleaning work. Space can be formed. As a result, the washbasin 1 can improve not only the design but also the workability.

The inclination angle θ with respect to the upper surface M of the counter 101A, which is the support surface on the inner surface 10A of the bowl portion 10 corresponding to the front bowl surface portion 11, is different from the inclination angle θ of the wall surface 21A, which is the outer surface of the front supported portion 20. As described above, the washbasin 1 is formed so that the inner surface 10A of the bowl portion 10 on the front pot surface portion 11 and the wall surface 21A on the front supported portion 20 have different inclination angles with respect to the respective support surfaces. The supported portion and the pot surface portion can be formed with a desired design without affecting each other's design. For example, even when a flat horizontal surface that can be used as a storage is formed on the pot surface portion, it can be realized by changing the shape of the hollow portion 16 while keeping the design of the front supported portion 20 as it is.

In the construction method of the washbasin 1, the supported portion 20 of the washbasin 1 is placed on the upper surface M of the counter 101A which is a pedestal, the lower end of the wall surface 21A of the outer wall portion 21 of the supported portion 20, and the upper surface of the counter 101A. A sealing material is applied between the M and the sealing material S to form the sealing processing portion S. As described above, in the construction method of the washbasin 1, the lower end portion of the wall surface 21A formed by the concave curved surface whose inclination angle with respect to the upper surface M of the counter 101A gradually increases from the upper end portion to the lower end portion. Since the sealing processing portion S is formed on the surface, the work of applying the sealing material can be easily performed using a finger or the like.

The bottom wall portions 22 and 32 of the supported portions 20 and 30 are outer contact surfaces 22A and 32A and inner contact surfaces 22B and 32B that abut on the upper surface M of the counter 101A, and groove-shaped portions provided between them. It has 22C and 32C. In this way, by forming the groove-shaped portions 22C and 32C between the outer contact surfaces 22A and 32A and the inner contact surfaces 22B and 32B, the stability when mounted on the support surface is improved. ..

The wash basin 1 sets the opening height between the wall surface 21A of the outer wall portion 21, which is the outer surface of the front supported portion 20, and the upper surface M of the counter 101A as a pedestal, with respect to the edge 11A of the front pot surface portion 11. It can be formed at a desired height within the range of height. Therefore, it is possible to secure a sufficient opening height for inserting a finger or the like when forming the sealing processing portion S. As a result, the sealing work can be easily performed.

In the wash basin 1, the hollow portion 16 is formed by the front pot surface portion 11 and the front supported portion 20. In the washbasin 1, in the front pot surface portion 11 and the front supported portion 20 forming the hollow portion 16, the edge 11A of the front pot surface portion 11 is formed by a curved surface protruding outward, and the outer surface of the front supported portion 20 is formed. Is formed by a concave curved surface. As described above, the surface shape of the front pot surface portion 11 and the outer surface shape of the front supported portion 20 can be desired designs that do not depend on each other. As a result, the washbasin 1 can be further improved in design.

The wall surface 21A of the front supported portion 20 is formed of a concave curved surface whose inclination angle with respect to the upper surface M of the counter 101A continuously and gradually increases from the upper end portion to the lower end portion. Therefore, when the sealing processing portion S is formed between the lower end portion of the wall surface 21A and the upper surface M of the counter 101A, the contact area between the sealing processing portion S and the wall surface 21A can be increased. That is, since the outer wall portion 21 is provided so as to tilt forward, the wall surface 21A is formed so as to be close to the upper surface M of the counter 101A. In this case, a large contact area with the sealing material is secured when the same amount of sealing material is applied, as compared with the case where the angle between the outer surface and the supporting surface is relatively large, such as when standing up in the vertical direction. can do.

The present disclosure is not limited to the disclosure of the first embodiment described by the above description and the drawings, and includes, for example, the following embodiments.
