Abstract
Description
- This application claims the priority of Japanese Application No. 2019-086040 filed Apr. 26, 2019, the entire contents of which are incorporated herein by reference.
- The present disclosure relates to a toilet bowl.
- Conventionally, a toilet bowl formed by joining an upper forming body and a lower forming body is known. For example, an upper forming body of a toilet bowl described in JP 2010-174450 A has an upper surface part forming an upper surface, and an inner wall part provided on a lower surface of the upper surface part. A lower end part of the inner wall part of the upper forming body and an outer edge part of the upper surface part thereof are joined to the lower forming body.
- However, in the above-described configuration, a joint surface with the lower forming body needs to be formed on the lower surface of the upper forming body so as to protrude greatly. For this reason, it is not easy to manufacture the upper forming body.
- The present disclosure has been completed based on the above circumstances, and an object of the present disclosure is to provide a toilet bowl whose upper forming body can be manufactured easily.
- The toilet bowl of the present disclosure includes: an upper forming body having an upper surface part that forms an upper surface of the toilet bowl in an installed state; and a lower forming body having an inner wall part and an outer wall part, the inner wall part being configured to be joined to an inner edge part of the upper surface part, the outer wall part being configured to be joined to an outer edge part of the upper surface part. In the toilet bowl, a space part is formed between the inner wall part and the outer wall part, and a dimension in an up-down direction from a lower end of the space part to an upper surface of the inner wall part is larger than a dimension in the up-down direction from an upper end of the space part to the upper surface of the inner wall part. Here, the inner edge part of the upper surface part is a portion of the upper surface part from a joint surface with the inner wall part to an inner end of the upper surface part.
- The toilet bowl of the present disclosure includes: an upper forming body having an upper surface part that forms an upper surface of the toilet bowl in an installed state; and a lower forming body having an inner wall part and an outer wall part, the inner wall part being configured to be joined to an inner edge part of the upper surface part, the outer wall part being configured to be joined to an outer edge part of the upper surface part. In the toilet bowl, in a portion above a water discharge port in a bowl part hanging down from the inner edge part of the upper surface part, a dimension of the lower forming body in an up-down direction is larger than a dimension of the upper forming body in the up-down direction.
- According to this disclosure, since a joint surface with the lower forming body does not need to be formed on the lower surface of the upper forming body so as to protrude greatly, the upper forming body can be manufactured easily.

FIG. 13 is a plan view showing a toilet bowl in a state in which an upper forming body and a lower forming body are joined, according to some embodiments. - Embodiments of the present disclosure will be described below. In the toilet bowl of the present disclosure, an inner edge part of the upper surface may be an inner edge curved surface bulging upward continuously from an inner end edge of an inner edge joint surface where a lower surface of the inner edge part of the upper surface part and the upper surface of the inner wall part are joined. According to such a configuration, the inner end edge of the inner edge joint surface is less noticeable, so that the appearance can be improved.
- In the toilet bowl of the present disclosure, an inner surface of an upper end part of the inner wall part may have an angle close to vertical. Here, a toilet bowl in which the inner surface of the upper end part of the inner wall part forms an angle close to vertical is called a so-called rimless toilet bowl, and in such a rimless toilet bowl, the inner end edge of the inner edge joint surface, when located on the substantially vertical inner surface, is conspicuous. However, according to the present disclosure, the inner end edge of the inner edge joint surface is located within the inner edge curved surface, and thus is less noticeable. Therefore, the appearance can be improved even when the toilet bowl has a rimless shape.
- In the toilet bowl of the present disclosure, an outer edge part of the upper surface may be an outer edge curved surface bulging upward continuously from an outer end edge of an outer edge joint surface where a lower surface of the outer edge part of the upper surface part and an upper surface of the outer wall part are joined. According to such a configuration, the outer end edge of the outer edge joint surface is less noticeable, so that the appearance can be improved.
- In the toilet bowl of the present disclosure, the outer edge joint surface may have an inclined part inclined obliquely downward from the outer end edge toward an inside. According to such a configuration, even if the outer edge curved surface has a small radius, a thickness dimension of the upper forming body can be ensured, so that the upper forming body can be manufactured easily.
- In the toilet bowl of the present disclosure, the inner edge joint surface may have an inclined part inclined obliquely downward from the inner end edge toward an outside. According to such a configuration, even if the inner edge curved surface has a small radius, the thickness dimension of the upper forming body can be ensured, so that the upper forming body can be manufactured easily.
- In the toilet bowl of the present disclosure, the lower surface of the inner edge part of the upper surface part may be larger in dimension in an inner-outer direction than the upper surface of the inner wall part, and the lower surface of the outer edge part of the upper surface part may be larger in dimension in the inner-outer direction than the upper surface of the outer wall part.

A depth dimension (dimension in the up-down direction) of thegroove part 44, that is, a height dimension (dimension in the up-down direction) of theinner wall part 41 and theouter wall part 42, respectively, is larger than a protrusion dimension of therib 33. A width dimension (dimension in the inner-outer direction) of thegroove part 44 is larger than a width dimension of therib 33. - In a state in which the upper forming
body 30 and the lower formingbody 40 are joined, a space part A is formed by being surrounded by theupper surface part 11, theinner wall part 41, theouter wall part 42, and the lower forming bodyupper surface part 43. Theinner wall part 41 and theouter wall part 42 are portions above a lower end of the space part A. As shown inFIG. 8 , an upper surface of the space part A is formed by the upper formingbody 30. Side surfaces of the space part A (left and right side surfaces inFIG. 8 ) are formed only by the lower formingbody 40. That is, inFIG. 8 , a dimension in the up-down direction from an upper end of the space part A to an inner edge lowerjoint surface 47U and a dimension in the up-down direction from the upper end of the space part A to an outer edge lowerjoint surface 47S are both zero. InFIG. 8 , the left side surface and right side surface of the space part A are a surface that stands from the lower end of the space part A to the upper left side and a surface that stands from the lower end of the space part A to the upper right side, respectively. - The
inner wall part 41 is provided along the upper end of thebowl part 12, as shown inFIG. 8 . Theinner wall part 41 constitutes theupright surface part 18. As shown inFIG. 7 , the shape of theinner wall part 41 is annular in plan view. The planar shape of theinner wall part 41 matches the planar shape of the inner edge upperjoint surface 39U of the upper formingbody 30. Theinner wall part 41 is substantially continuous over the entire periphery except for a part where thewater discharge port 24 is formed. As shown inFIGS. 3 and 5 , theinner wall part 41 has an inclinedinner wall part 41K whose upper surface is inclined along the inclination of the lower surface of the water passageupper part 31. - As shown in
FIG. 7 , theouter wall part 42 has a firstouter wall part 45 provided continuously from the front side of the lower formingbody 40 to both left and right sides thereof, and a secondouter wall part 46 provided so as to connect back ends of the firstouter wall part 45 right and left. The firstouter wall part 45 constitutes theperipheral wall part 13. An upper surface of the firstouter wall part 45 is a substantially horizontal surface as shown inFIG. 8 . The upper surface of the firstouter wall part 45 is located at substantially the same height as an upper surface of theinner wall part 41. An upper surface of the secondouter wall part 46 is located below the upper surface of the firstouter wall part 45, as shown inFIG. 5 . As shown inFIG. 7 , the secondouter wall part 46 has a firstlateral part 46F, a secondlateral part 46S, and a pair oflongitudinal parts 46T, as in theprojection part 37 of the upper formingbody 30. - The upper surface of the lower forming
body 40 is provided with a joint surface with the upper forming body 30 (referred to as lower joint surface 47). As shown inFIG. 7 , the lowerjoint surface 47 has the inner edge lowerjoint surface 47U constituted of the upper surface of the inner wall part 41 (including the inclinedinner wall part 41K), and the outer edge lowerjoint surface 47S constituted of the upper surface of theouter wall part 42. As shown inFIG. 4 , a width dimension (dimension in the inner-outer direction) of the inner edge lowerjoint surface 47U is smaller than a width dimension of the inner edge upperjoint surface 39U. A width dimension of the outer edge lowerjoint surface 47S is smaller than a width dimension of the outer edge upperjoint surface 39S. - The upper forming
body 30 and lower formingbody 40 thus formed are joined. Intermediate molded products having the shape of the upper formingbody 30 and the lower formingbody 40 are manufactured by use of a mold (not shown), and a joining slurry is applied to the upperjoint surface 39 and the lowerjoint surface 47 of the intermediate molded product for joining. At this time, as shown inFIG. 8 , an inner end edge of the inner edge upperjoint surface 39U and an inner end edge of the inner edge lowerjoint surface 47U are aligned so as not to be deviated in a plane direction. An outer end edge of the outer edge upperjoint surface 39S and the outer end edge of the outer edge lowerjoint surface 47S are also aligned so as not to be deviated in a plane direction. As shown inFIG. 4 , since the width dimension of the inner edge upperjoint surface 39U is larger than the width dimension of the inner edge lowerjoint surface 47U, an inner portion of the inner edge upperjoint surface 39U is exposed. Since the width dimension of the outer edge upperjoint surface 39S is larger than the width dimension of the outer edge lowerjoint surface 47S, an inner portion of the outer edge upperjoint surface 39S is exposed. The upper formingbody 30 and the lower formingbody 40 are thus joined, dried and fired to complete thetoilet bowl 10. - In the
toilet bowl 10 in a completed state, thejoint surface 27 between the lower formingbody 40 and the upper formingbody 30 is located at the lower ends R1 of the inner edge curvedsurface 26U and the outer edge curvedsurface 26S, as shown inFIG. 8 . Thejoint surface 27 has an inner edgejoint surface 27U formed by joining the inner edge upperjoint surface 39U and the inner edge lowerjoint surface 47U, and an outer edgejoint surface 27S formed by joining the outer edge upperjoint surface 39S and the outer edge lowerjoint surface 47S. Aninner end edge 28 of thejoint surface 27 is an inner end edge of the inner edge upperjoint surface 39U and the inner edge lowerjoint surface 47U. Theinner end edge 28 of thejoint surface 27 is formed along a lower end of the inner edge curvedsurface 26U over the entire periphery except for a portion corresponding to the water passageupper part 31. Anouter end edge 29 of thejoint surface 27 is an outer end edge of the outer edge upperjoint surface 39S and the outer edge lowerjoint surface 47S. Theouter end edge 29 of thejoint surface 27 is formed along the lower end R1 of the outer edge curvedsurface 26S over the entire periphery except for the back end part of therim part 14 and the connectingpart 15. The back end part of therim part 14 and theouter end edge 29 of thejoint surface 27 of the connectingpart 15 are covered and hidden with a cover member (not shown). - Next, the actions and effects of the embodiments configured as described above will be described.
- The
toilet bowl 10 of some embodiments includes the upper formingbody 30 having theupper surface part 11 that forms the upper surface; and the lower formingbody 40 having theinner wall part 41 which is joined to the inner edge part of theupper surface part 11, and theouter wall part 42 which is joined to the outer edge part of theupper surface part 11. According to this configuration, since the upperjoint surface 39, which is the joint surface with the lower formingbody 40, does not need to be formed on thelower surface 30U of the upper formingbody 30 so as to protrude, the upper formingbody 30 can be manufactured easily. - The inner edge part of the upper surface is the inner edge curved
surface 26U bulging upward continuously from theinner end edge 28 of the inner edgejoint surface 27U where the lower surface of the inner edge part of theupper surface part 11 and the upper surface of theinner wall part 41 are joined. According to this configuration, theinner end edge 28 of the inner edgejoint surface 27U is less noticeable, so that the appearance can be improved. - In an installed state, the inner surface of the upper end part of the
inner wall part 41 has an angle close to vertical. In the so-calledrimless toilet bowl 10, theinner end edge 28 of the inner edgejoint surface 27U, when located on the substantially vertical wall surface, is conspicuous. However, according to thetoilet bowl 10 of some embodiments, theinner end edge 28 of the inner edgejoint surface 27U is located within the range of the inner edge curvedsurface 26U, and thus is less noticeable. Therefore, the appearance can be improved even when thetoilet bowl 10 has a rimless shape. - The outer edge part of the upper surface is the outer edge curved
surface 26S bulging upward continuously from theouter end edge 29 of the outer edgejoint surface 27S where the lower surface of the outer edge part of theupper surface part 11 and the upper surface of theouter wall part 42 are joined. According to this configuration, theouter end edge 29 of the outer edgejoint surface 27S is less noticeable, so that the appearance can be improved. - Next, a
toilet bowl 50 according to some embodiments will be described with reference toFIGS. 9 and 10 . - The
toilet bowl 50 of some embodiments comprises outer edgejoint surface 27S having aninclined part 52 inclined obliquely downward from theouter end edge 29 toward an inside. - The
toilet bowl 50 according to some embodiments is formed by joining the upper formingbody 30 and the lower formingbody 40. The upper formingbody 30 has theupper surface part 11, and the upperjoint surface 39 is provided on the lower surface of the upper formingbody 30. The upper formingbody 30 has a flat plate shape. That is, a height dimension of a step D formed on the lower surface of the upper formingbody 30 is not more than the average height of the upper formingbody 30, and is not more than half of the average height thereof. - The upper
joint surface 39 has the inner edge upperjoint surface 39U provided on the inner peripheral side of the upper formingbody 30, and the outer edge upperjoint surface 39S provided on the outer peripheral side of the upper formingbody 30. The inner edge part of theupper surface part 11 of the upper formingbody 30 has anoverhang part 55 protruding inward relative to theinner wall part 41 of the lower formingbody 40. That is, the inner edge part of theupper surface part 11 includes a portion from the joint surface with the inner wall part 41 (inner edge upperjoint surface 39U) to a tip end of theoverhang part 55. In some embodiments, the inner edge curvedsurface 26U and the outer edge curvedsurface 26S are formed on the inner edge part and the outer edge part, respectively, of the upper surface of the upper formingbody 30. - In some embodiments, the lower forming
body 40 has theinner wall part 41 joined to the inner edge part of theupper surface part 11 and theouter wall part 42 joined to the outer edge part of theupper surface part 11, and the lowerjoint surface 47 is provided on the upper surface of the lower formingbody 40. In some embodiments, the lowerjoint surface 47 has the inner edge lowerjoint surface 47U constituted of the upper surface of theinner wall part 41, and the outer edge lowerjoint surface 47S constituted of the upper surface of theouter wall part 42. - The outer edge
joint surface 27S (the outer edge upperjoint surface 39S and the outer edge lowerjoint surface 47S) has aninclined part 52 inclined obliquely upward from thelower surface 30U of the upper formingbody 30 toward the outer edge curvedsurface 26S. The outer end edge of the inclined part 52 (theouter end edge 29 of the outer edgejoint surface 27S) shown inFIG. 9 is located at the lower end R1 of the outer edge curvedsurface 26S. The outer end edge of the inclined part 52 (theouter end edge 29 of the outer edgejoint surface 27S) shown inFIG. 10 is located in the middle of the outer edge curvedsurface 26S. Thelower surface 30U of the upper formingbody 30 is located below the lower end R1 of the outer edge curvedsurface 26S in each of the toilet bowls 50 shown inFIGS. 9 and 10 . The thickness dimension (dimension in the up-down direction) H1 of therim part 14 of the upper formingbody 30 is larger than the radius of the outer edge curvedsurface 26S. In the upper formingbody 30, a portion that is above theinclined part 52 has a greater thickness dimension in thetoilet bowl 50 shown inFIG. 9 than in thetoilet bowl 50 shown inFIG. 10 . Thus, by changing the inclination angle of theinclined part 52, the thickness dimension of the upper formingbody 30 can be changed. - As described above, since the outer edge
joint surface 27S has theinclined part 52 inclined obliquely downward from theouter end edge 29 toward the inside, the thickness dimension of the upper formingbody 30 can be ensured even if the outer edge curvedsurface 26S has a small radius. - Next, a
toilet bowl 60 which embodies the present disclosure will be described with reference toFIG. 11 . - The
toilet bowl 60 of some embodiments comprises anoverhang part 61 in which the inner edge part of theupper surface part 11 protrudes inward relative to theinner wall part 41 of the lower formingbody 40, and that aleg part 62 is provided on thelower surface 30U of the upper formingbody 30. - In the
toilet bowl 60 according to some embodiments, the outer edgejoint surface 27S has theinclined part 52 inclined obliquely downward from theouter end edge 29 toward the inside. The upper formingbody 30 has theleg part 62 hanging down from theupper surface part 11 at the position corresponding to theinner wall part 41. A lower surface of theleg part 62 constitutes the inner edge upperjoint surface 39U which is joined to the upper surface of the inner wall part 41 (inner edge lowerjoint surface 47U). Since the upper formingbody 30 has theleg part 62, the strength of the upper formingbody 30 can be increased. Since theoverhang part 61 overhangs above theinner end edge 28 of thejoint surface 27, theinner end edge 28 of thejoint surface 27 is difficult to see, so that the deterioration in appearance can be prevented. - In the
toilet bowl 60 according to some embodiments, the space part A is formed between theinner wall part 41 and theouter wall part 42. Thus, in a state in which the upper formingbody 30 and the lower formingbody 40 are joined, a space part A is formed by being surrounded by theupper surface part 11, theinner wall part 41, theouter wall part 42, and the lower forming bodyupper surface part 43. In some embodiments, the upper surface of the space part A is formed by the upper formingbody 30, as shown inFIG. 11 . Side surfaces of the space part A (left and right side surfaces inFIG. 11 ) are formed by the upper formingbody 30 and the lower formingbody 40. Specifically, one side surface (side surface on the side of the outer wall part 42) of the space part A is formed only by the lower formingbody 40. The other side surface (side surface on the side of the inner wall part 41) of the space part A is formed by the upper formingbody 30 and the lower formingbody 40. In the other side surface of the space part A, a height dimension H5 of the lower forming body 40 (dimension in the up-down direction from the lower end of the space part A to the inner edge lowerjoint surface 47U) is larger than a height dimension H6 of the upper forming body (dimension in the up-down direction from the upper end of the space part A to the inner edge lowerjoint surface 47U). The height dimension H5 of the lower formingbody 40 is a dimension in the up-down direction of theinner wall part 41. In the side surfaces of the space part A, it is desirable that the height dimension H6 of the upper formingbody 30 be not more than half of the height dimension H5 of the lower formingbody 40. - Next, a
toilet bowl 70 which embodies the present disclosure will be described with reference toFIG. 12 . - The
toilet bowl 70 of some embodiments is different from that of the first embodiment in that no space part is formed between theinner wall part 41 and theouter wall part 42, that is, a space between theinner wall part 41 and theouter wall part 42 is filled. - The
toilet bowl 70 according to some embodiments is formed by joining the upper formingbody 30 and the lower formingbody 40. The upper formingbody 30 has theupper surface part 11, and the upperjoint surface 39 is provided on the lower surface of the upper formingbody 30, as in the first embodiment. The upperjoint surface 39 has the inner edge upperjoint surface 39U provided on the inner peripheral side of the upper formingbody 30, and the outer edge upperjoint surface 39S provided on the outer peripheral side of the upper formingbody 30. As in the first embodiment, the inner edge curvedsurface 26U and the outer edge curvedsurface 26S are formed on the inner edge part and the outer edge part, respectively, of the upper surface of the upper formingbody 30. - In some embodiments, the lower forming
body 40 has theinner wall part 41 joined to the inner edge part of theupper surface part 11, and theouter wall part 42 joined to the outer edge part of theupper surface part 11. Theinner wall part 41 is the inner portion of the upper end part of the lower formingbody 40, and theouter wall part 42 is the outer portion of the upper end part of the lower formingbody 40. - The lower
joint surface 47 is provided on the upper surface of the lower formingbody 40. In some embodiments, the lowerjoint surface 47 has the inner edge lowerjoint surface 47U constituted of the upper surface of theinner wall part 41, and the outer edge lowerjoint surface 47S constituted of the upper surface of theouter wall part 42. The upper surface of the lower formingbody 40 is a plane, and the inner edge lowerjoint surface 47U and the outer edge lowerjoint surface 47S are each a part of the same plane. - In a portion above the water discharge port 24 (referred to as rim inner wall surface R) in the
bowl part 12 hanging down from the inner edge part of the upper surface part, a height dimension (dimension in the up-down direction) H7 of the lower formingbody 40 is larger than a height dimension (dimension in the up-down direction) H8 of the upper formingbody 30. The rim inner wall surface R refers to a portion from an upper end position of the shelf part 19 (height position of the water discharge port 24) to the upper surface of theupper surface part 11 as shown inFIG. 4 . - The present disclosure is not limited to the embodiments described by the above description and drawings, and the following embodiments are also included in the technical scope of the present disclosure.
- In some embodiments, the upper forming
body 30 has a whole of the entireupper surface part 11 of the toilet bowls 10, 50, 60 and 70, but the present disclosure is not limited thereto. The upper formingbody 30 may have only a part of theupper surface part 11 of the toilet bowl. For example, as shown inFIG. 13 , only a portion, including the connectingpart 15 and the water passageupper part 31, of theupper surface part 11 of atoilet bowl 80 may be formed as an upper formingbody 81, and the other portion may be integrally formed with a lower formingbody 82. - In some embodiments, the inner edge curved
surface 26U is equal, in radius, to the outer edge curvedsurface 26S. However, the present disclosure is not limited to this. The inner edge curved surface and the outer edge curved surface may have different radii. - In some embodiments, the
inner end edge 28 of thejoint surface 27 between the lower formingbody 40 and the upper formingbody 30 is located within the inner edge curvedsurface 26U, and theouter end edge 29 of thejoint surface 27 is located within the range of the outer edge curvedsurface 26S. However, the present disclosure is not limited to this, and the inner end edge and outer end edge of the joint surface may not necessarily be located within the curved surfaces, or only one of them may be located within the curved surface. - The above embodiments have exemplified the cases where the present disclosure is applied to the so-called rimless toilet bowls 10, 50, 60, 70 and 80. However, the present disclosure is not limited to this, and can also be applied to a rimmed toilet bowl.
- In some embodiments, the outer edge
joint surface 27S has theinclined part 52 inclined obliquely downward from theouter end edge 29 toward the inside, but the present disclosure is not limited thereto. The inner edge joint surface may have an inclined part inclined obliquely downward from the inner end edge toward the outside.
