Description

本発明は、胴部と、胴部の上面に接合されるリム部と、を備える便器に関する。 The present invention relates to a toilet comprising a trunk and a rim joined to the upper surface of the trunk.

従来、胴部と、胴部の上面に接合されるリム部と、を備える便器が知られている（例えば、特許文献１参照）。特許文献１に記載の便器においては、胴部とリム部との接合部は、接着部材である泥しょうを胴部に載せやすいように、ほぼ水平なライン状に形成されている。胴部とリム部とは、接着部材である泥しょうにより接合されて、その後、焼成される。 Conventionally, a toilet having a trunk and a rim joined to the upper surface of the trunk is known (for example, see Patent Document 1). In the toilet bowl described in Patent Document 1, the joint portion between the trunk portion and the rim portion is formed in a substantially horizontal line shape so that mud as an adhesive member can be easily placed on the trunk portion. The body portion and the rim portion are joined together by mud, which is an adhesive member, and then fired.

ところで、一般的に、便器装置においては、便器の後部の上部には、機能部が配置される。便器装置の後方側に機能部を配置する場合に、便器装置全体の高さを小さくするために、機能部を収容する収容部を、便器の上面を窪ませて形成し、窪ませた収容部に機能部を収容して、機能部を低い位置に配置することがある。 By the way, generally, in a toilet device, a functional unit is arranged at the upper part of the rear part of the toilet. In order to reduce the height of the entire toilet device when the functional unit is arranged on the rear side of the toilet device, a storage unit for storing the functional unit is formed by recessing the upper surface of the toilet, and the concave storage unit In some cases, the functional unit is accommodated and the functional unit is disposed at a low position.

特開２０１４−０３４８６８号公報JP 2014-034868 A

機能部を配置する収容部を便器の上面を窪ませて形成する場合には、リム部の位置を下方に下げて収容部の空間を確保することが考えられる。しかし、リム部の位置を下方に下げる場合には、胴部とリム部との接合部の位置も下方に下げる必要性が生じる。胴部とリム部との接合部の位置を下げると、胴部とリム部との接合部が、便器の側面の上下方向の途中に位置するため、胴部とリム部との接合部における外部に露出する接合ラインが、便器の側面における上端部に近い側に位置するよりも、目立ちやすくなる。これにより、便器の外観の品位が低下する虞がある。
そのため、胴部とリム部との接合部について、外観の品位を向上できる便器が望まれる。 In the case where the accommodation portion in which the functional portion is disposed is formed by recessing the upper surface of the toilet bowl, it is conceivable that the position of the rim portion is lowered to secure the space of the accommodation portion. However, when the position of the rim portion is lowered, it is necessary to lower the position of the joint portion between the body portion and the rim portion. If the position of the joint part between the trunk part and the rim part is lowered, the joint part between the trunk part and the rim part is located in the vertical direction of the side surface of the toilet. The joint line exposed to the surface of the toilet is more conspicuous than being located on the side close to the upper end of the side surface of the toilet. Thereby, there exists a possibility that the quality of the appearance of a toilet bowl may fall.
Therefore, a toilet that can improve the appearance quality of the joint between the trunk and the rim is desired.

このような製造工程を経て、図２及び図３に示すように、胴部２１及びリム部２２が接合さることで、便器２が製造される。 The manufacturing process of the toilet 2 will be specifically described. The toilet bowl 2 is made of earthenware, and is manufactured through a molding process, a joining process, a drying process, a glazing process, and a firing process. In the molding step, the body portion 21 constituting the lower portion of the toilet bowl 2 and the rim portion 22 constituting the upper portion of the toilet bowl 2 are separately cast and molded. In the joining step, mud as an adhesive member is disposed between the trunk portion 21 and the rim portion 22, the rim portion 22 is overlaid on the trunk portion 21, and the trunk portion 21 and the rim portion 22 are joined. In the drying step, the joined portion of the body portion 21 and the rim portion 22 joined in the joining step is dried. In the glazing process, glaze is applied to the surface of the toilet 2 in order to decorate the body part 21 and the rim part 22 dried in the drying process and prevent moisture absorption. In the baking process, the toilet bowl 2 glazed in the glazing process is baked.
As shown in FIGS. 2 and 3, the toilet bowl 2 is manufactured by joining the trunk portion 21 and the rim portion 22 through such a manufacturing process.

接合工程において接合される胴部２１及びリム部２２の詳細について説明する。
胴部２１は、図２及び図４に示すように、便器２の下方に配置され、図４に示すように、周壁２１１や、洗浄水の流路を構成する流路構成部２１２や、汚物受け面２１３などを有し、便器装置１の台座部分を構成する。 The detail of the trunk | drum 21 and the rim | limb part 22 joined in a joining process is demonstrated.
As shown in FIGS. 2 and 4, the trunk portion 21 is disposed below the toilet bowl 2, and as shown in FIG. 4, the peripheral wall 211, the flow path component 212 that forms the flow path of the washing water, and the filth It has the receiving surface 213 etc. and comprises the base part of the toilet device 1. FIG.

リム部２２は、胴部２１の上面に接合される。リム部２２は、平面視で中央に開口部２２１を有した環状に形成される。リム部２２は、胴部２１の上端部の周縁に沿うように配置され、胴部２１の上端部の外周縁から便器２の内側に張り出すように突出して形成される。 The rim portion 22 is joined to the upper surface of the trunk portion 21. The rim portion 22 is formed in an annular shape having an opening 221 in the center in plan view. The rim portion 22 is disposed along the peripheral edge of the upper end portion of the trunk portion 21, and is formed so as to protrude from the outer peripheral edge of the upper end portion of the trunk portion 21 to the inside of the toilet 2.

リム部２２は、図２に示すように、機能部４を収容する収容部として機能部収容部５を有する。機能部収容部５は、便器２の後方側において、リム部２２の上面に形成される。機能部収容部５は、機能部４（図１参照）を配置するために、便器２の上面から下方に窪むように形成される。機能部収容部５を便器２の上面から下方に窪むように形成することで、機能部４を低い位置に配置して、便器装置１の全体の高さを小さくできる。なお、本実施形態において、機能部収容部５は、便器２の左右に対称の形状である。そのため、本実施形態においては、機能部収容部５の左右方向の形状について、左右方向の一方側についてのみ説明する場合がある。 As shown in FIG. 2, the rim part 22 has a functional part accommodating part 5 as an accommodating part for accommodating the functional part 4. The functional part accommodating part 5 is formed on the upper surface of the rim part 22 on the rear side of the toilet bowl 2. The functional part accommodating part 5 is formed so as to be recessed downward from the upper surface of the toilet bowl 2 in order to arrange the functional part 4 (see FIG. 1). By forming the functional part accommodating part 5 so as to be recessed downward from the upper surface of the toilet bowl 2, the functional part 4 can be arranged at a low position and the overall height of the toilet device 1 can be reduced. In addition, in this embodiment, the function part accommodating part 5 is a symmetrical shape on the left and right of the toilet bowl 2. Therefore, in this embodiment, only the one side of the left-right direction may be demonstrated about the shape of the functional part accommodating part 5 in the left-right direction.

機能部収容部５は、図２及び図５に示すように、収容部側接合部１３から、便器２の左右方向の内側に延びて形成され、下り傾斜部５３を経て、窪んで形成される。機能部収容部５は、図２及び図５に示すように、一対の外壁部５１と、一対の中段部５２と、一対の下り傾斜部５３と、底面部５４と、を有する。一対の外壁部５１と、一対の中段部５２と、一対の下り傾斜部５３は、便器２の左右方向に離間して配置される。 As shown in FIGS. 2 and 5, the functional part accommodating part 5 is formed to extend from the accommodating part side joining part 13 to the inner side in the left-right direction of the toilet bowl 2, and is formed to be depressed through the downward inclined part 53. . As shown in FIG. 2 and FIG. 5, the functional part accommodating part 5 includes a pair of outer wall parts 51, a pair of middle step parts 52, a pair of descending inclined parts 53, and a bottom part 54. The pair of outer wall portions 51, the pair of middle step portions 52, and the pair of descending inclined portions 53 are arranged apart from each other in the left-right direction of the toilet 2.

図５に示すように、外壁部５１は、便器２の左右方向の外縁において、収容部側接合部１３から上方に立ち上がる（突出する）ように形成される。
中段部５２は、外壁部５１の下端から便器２の左右方向の内側に水平方向に延びる。 As shown in FIG. 5, the outer wall portion 51 is formed so as to rise (project) upward from the accommodating portion side joint portion 13 at the outer edge in the left-right direction of the toilet bowl 2.
The middle step portion 52 extends in the horizontal direction from the lower end of the outer wall portion 51 to the inner side in the left-right direction of the toilet bowl 2.

下り傾斜部５３は、中段部５２における便器２の左右方向の内側の端部から便器２の内側に向かうに従って下るように傾斜して延びる。下り傾斜部５３の傾斜角度αは、リム部２２における機能部収容部５の下部において、胴部２１とリム部２２とが接合されることを考慮して、胴部２１の上面に、接着部材としての泥しょうを載せやすい傾斜角度で形成される。例えば、下り傾斜部５３の傾斜角度αは、胴部２１の上面に接着部材としての泥しょうを載せやすいように、水平方向に対して、４５°以下であることが好ましい。例えば、本実施形態においては、下り傾斜部５３の傾斜角度αは、水平方向に対して、４５°である。 The descending inclined portion 53 extends so as to descend from the inner end portion in the left-right direction of the toilet bowl 2 toward the inner side of the toilet bowl 2 in the middle stage portion 52. The inclination angle α of the descending inclined portion 53 is set on the upper surface of the body portion 21 in consideration of the fact that the body portion 21 and the rim portion 22 are joined to each other at the lower portion of the functional portion accommodating portion 5 in the rim portion 22. It is formed at an inclination angle that makes it easy to put mud. For example, the inclination angle α of the downward inclined portion 53 is preferably 45 ° or less with respect to the horizontal direction so that mud as an adhesive member can be easily placed on the upper surface of the trunk portion 21. For example, in the present embodiment, the inclination angle α of the downward inclination portion 53 is 45 ° with respect to the horizontal direction.

底面部５４は、下り傾斜部５３における便器２の左右方向の内側の端部から水平方向に延びる。底面部５４は、機能部収容部５における便器２の左右方向の中央に位置し、機能部収容部５における最も低い位置に形成される。底面部５４の上面には、機能部４が配置される。 The bottom surface portion 54 extends in the horizontal direction from an inner end portion of the downward inclined portion 53 in the left-right direction of the toilet bowl 2. The bottom surface portion 54 is located at the center in the left-right direction of the toilet bowl 2 in the functional portion accommodating portion 5 and is formed at the lowest position in the functional portion accommodating portion 5. The functional unit 4 is disposed on the upper surface of the bottom surface part 54.

便器２は、図２に示すように、胴部２１及びリム部２２の接合部として、外部側接合ライン１１と、第１内部側接合ライン１６と、第２内部側接合ライン１７と、収容部支持接合ライン１８と、を備える。胴部２１及びリム部２２の接合部の接合面は、外部側接合ライン１１、第１内部側接合ライン１６、第２内部側接合ライン１７及び収容部支持接合ライン１８の各ラインが延びる方向に直交する断面において、図５及び図６に示す外部側接合ライン１１のように、水平方向に幅を有した水平面となっている。 As shown in FIG. 2, the toilet bowl 2 includes an outer side joining line 11, a first inner side joining line 16, a second inner side joining line 17, and a storage portion as a joining portion of the trunk portion 21 and the rim portion 22. And a support joining line 18. The joint surface of the joint part of the trunk | drum 21 and the rim | limb part 22 is in the direction where each line of the outer side joining line 11, the 1st inside side joining line 16, the 2nd inside side joining line 17, and the accommodating part support joining line 18 extends. In an orthogonal cross section, a horizontal plane having a width in the horizontal direction is formed as in the outer side joining line 11 shown in FIGS. 5 and 6.

外部側接合ライン１１は、図２及び図３に示すように、便器２の外側の側面に沿って形成されている。外部側接合ライン１１は、便器２の上端部よりも下方の位置における便器２の上端部寄りにおいて、便器２の後部を除いた便器２の前方側に形成される。外部側接合ライン１１は、平面視で略Ｕ字形状に延びて形成されている。外部側接合ライン１１は、便器２の側面において外部に露出しており、便器２の外部から視認できる。なお、本実施形態において、外部側接合ライン１１は、便器２の左右に対称の形状である。そのため、本実施形態においては、外部側接合ライン１１における左右に対称の部分については、外部側接合ライン１１における左右の一方側についてのみ説明する。 The outer side joining line 11 is formed along the outer side surface of the toilet bowl 2 as shown in FIG.2 and FIG.3. The outer joint line 11 is formed on the front side of the toilet 2 except for the rear portion of the toilet 2 near the upper end of the toilet 2 at a position below the upper end of the toilet 2. The outer side joining line 11 is formed extending in a substantially U shape in plan view. The external side joining line 11 is exposed to the outside on the side surface of the toilet 2 and can be visually recognized from the outside of the toilet 2. In the present embodiment, the outer side joining line 11 has a symmetrical shape on the left and right of the toilet bowl 2. Therefore, in the present embodiment, only the left and right sides of the outer joint line 11 will be described with respect to the left and right symmetrical parts of the outer joint line 11.

外部側接合ライン１１（胴部２１とリム部２２の外周部の接合部）は、図２及び図３に示すように、前方側接合部１２と、収容部側接合部１３と、を有する。 The outer side joining line 11 (joint part of the outer peripheral part of the trunk | drum 21 and the rim | limb part 22) has the front side junction part 12 and the accommodating part side junction part 13, as shown in FIG.2 and FIG.3.

前方側接合部１２は、図２及び図３に示すように、機能部収容部５よりも便器２の前方側における胴部２１とリム部２２との接合部である。前方側接合部１２は、収容部側接合部１３よりも前方側において、便器２の前方側に形成される略Ｕ字形状の部分に沿って形成される接合部である。 As shown in FIGS. 2 and 3, the front side joint portion 12 is a joint portion between the trunk portion 21 and the rim portion 22 on the front side of the toilet 2 relative to the functional portion housing portion 5. The front side joint portion 12 is a joint portion formed along a substantially U-shaped portion formed on the front side of the toilet bowl 2 in front of the accommodating portion side joint portion 13.

前方側接合部１２において、図６に示すように、胴部２１の側面に連続するリム部２２の端部２２ａの外面は、便器２の外方に凸となるＲ形状（以下、「Ｒ端形状」ともいう。）に形成される。リム部２２の端部２２ａの外面がＲ端形状を有することで、前方側接合部１２がＲ形状の端部の直ぐ下方に位置するため、胴部２１とリム部２２との接合部が目立ち難くなる。 As shown in FIG. 6, the outer surface of the end portion 22 a of the rim portion 22 that is continuous with the side surface of the trunk portion 21 in the front joint portion 12 has an R shape (hereinafter referred to as “R end”) that protrudes outward from the toilet 2. It is also called “shape”.) Since the outer surface of the end portion 22a of the rim portion 22 has the R-end shape, the front-side joint portion 12 is positioned immediately below the R-shape end portion, and thus the joint portion between the body portion 21 and the rim portion 22 is conspicuous. It becomes difficult.

収容部側接合部１３は、機能部収容部５における胴部２１とリム部２２との接合部である。収容部側接合部１３は、機能部収容部５における便器２の左右方向の両端部に形成される接合部である。 The accommodating portion side joining portion 13 is a joining portion between the body portion 21 and the rim portion 22 in the functional portion accommodating portion 5. The accommodating part side joining part 13 is a joining part formed in the both ends of the left-right direction of the toilet bowl 2 in the functional part accommodating part 5.

収容部側接合部１３の接合位置は、図３に示すように、上下方向において、前方側接合部１２の接合位置よりも下方に位置する。
