Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a toilet, a mold for the same, and a method for manufacturing the toilet.
[0002]
[Prior art]
Generally, a toilet includes a toilet body having a ball portion, and the ball portion is surrounded by a rim at the upper edge thereof. In the production of such a toilet, the bases of the rim and the toilet body are separately molded, and the bases are joined and fired.
[0003]
[Problems to be solved by the invention]
By the way, the shape of the toilet bowl and its appearance design are various. Therefore, the toilet body that forms this peripheral appearance also has various appearances, for example, the appearance and shape of the spread, and it has been necessary to mold such a toilet body individually.
[0004]
However, no special consideration has been given to the connection between the toilet body and the ball portion of the toilet body. In other words, the ball portion is surrounded by the toilet body, and the ball portion is merely continuously connected to the inner wall of the toilet body at its upper end to form both. For this reason, even in the ball part, along with the change of the toilet body, for example, the ball part itself is designed in accordance with the widening or shape change of the toilet body, and the ball part is molded integrally with the toilet body. It was the current state of molding.
[0005]
For this reason, in the toilet bowl with different appearance designs, the shape of the inner wall surface of the ball portion is also different. Therefore, the cleaning function such as the state of accumulated water in the ball part, the mechanism for supplying cleaning water to the ball part, and the behavior of the cleaning water in the ball part during water supply is different for each toilet. Since these washing functions affect the toilet performance, it is necessary to carry out the water supply design to the ball portion and the examination of the washing water behavior for each toilet in parallel with the appearance design of the toilet. In addition, since the toilet bowl needs to be designed and the mold is designed and manufactured, it takes a long time to manufacture the toilet bowl.
[0006]
The same applies to the rim, and the rim was simply placed and connected to the toilet body. For this reason, even in the rim, along with the change in the toilet body, for example, the shape of the rim itself is designed in accordance with the widening of the toilet body, and the rim corresponding to the toilet body is molded. Was the current situation.
[0007]
The present invention has been made to solve the above-described problems, and provides a new method for manufacturing a toilet having a ball portion surrounded by a rim at its upper edge, and also aims to simplify the manufacture of the toilet. And
[0008]
[Means for solving the problems and their functions and effects]
  In order to solve at least a part of this problem, the toilet of the present invention surrounds a toilet inner surface wall that forms a ball portion with an outer appearance wall that forms the peripheral appearance of the toilet, and this outer appearance wall and the inner surface of the toilet bowl are connected to the inner / outer wall connecting portion. Connect through. And the exterior appearance of the toilet bowl, the exterior wall and this exteriorExtend from the top of the wall and remove the rim on the side of the exterior wallForm with surrounding rim enclosure wallTo do. As for the rim, this is a rim having a hollow portion formed below the seating portion that becomes the seating surface of the toilet seat, and a rim connecting portion that extends the seating portion to the toilet peripheral side.The top of the inner wall of the toilet bowlBy connecting the lower end of the hollow part to the inner wall of the toiletThe outer wall is surrounded by a rim.By connecting the rim connection part to the wall,ViewSupport on the wallGet. Then, the rim wall on the exterior wall side forming the hollow portion of the rim, the rim connecting portion, the rim surrounding wall, and the inner and outer wall connecting portions form a hollow region surrounding the hollow portion of the rim below the rim connecting portion. ThisThus, even if the peripheral appearance of the toilet bowl changes, this change in appearance can be dealt with only by changing the shape of the external wall and the rim enclosure wall. What is necessary is just to change the condition (for example, a shape, a magnitude | size, etc.) of a connection part. Therefore, since the shape change is not required for the toilet inner wall when changing the peripheral appearance of the toilet bowl, the toilet inner wall forming the ball portion can be made common regardless of the peripheral appearance of the toilet bowl.
[0009]
In addition, the rim has an opening for defecation (rim opening) facing the ball portion because it is around the upper edge of the ball portion. The rim opening can be standardized regardless of the peripheral appearance of the toilet bowl. By the way, as described above, the rim is supported by the upper end of the toilet inner wall on the ball portion side, and the toilet inner wall is made common regardless of the peripheral appearance of the toilet. Therefore, the connection location between the rim on the ball portion side and the upper end of the toilet inner wall can be shared regardless of the peripheral appearance of the toilet. Further, if the peripheral appearance of the toilet bowl changes, it is sufficient to change the shape, size, etc. of the rim in accordance with the change of the peripheral appearance of the toilet bowl with respect to the connection state with the external wall via the rim surrounding wall.
[0012]
The toilet of the present invention having the above-described configuration can also take the following aspects. That is, the exterior wall and the toilet inner wall are connected to the inner / outer wall connecting portion at the upper end side connecting portion near the upper end of the toilet inner wall and the inner / outer wall connecting portion at the lower end side connecting portion on the lower end side of the toilet inner wall. It can be connected with parts.
[0013]
This is preferable because the inner wall of the toilet bowl can be firmly fixed to the exterior wall at the two inner and outer wall connecting portions, and the stability of holding the inner wall of the toilet bowl is increased.
[0014]
  Further, the rim is connected to the upper end of the rim surrounding wall by extending a seating portion serving as a seating surface of the toilet seat to the toilet periphery side.Therefore, no step is left on the seating surface of the toilet seat, so that the appearance can be improved. In particular, if the connecting portion between the rim and the upper end of the rim surrounding wall is a corner on the outer periphery of the rim, the appearance is further improved.
[0016]
Furthermore, the rim and the rim surrounding wall can be easily connected by extending the seating portion of the toilet seat in accordance with the shape of the rim surrounding wall of the appearance wall in accordance with the peripheral appearance change of the toilet bowl.
[0017]
Such an extension of the seating area around the toilet can be extended slightly inclined downward from the seating area, in addition to the horizontal extension from the seating area.
[0018]
In addition, the rim has a hollow portion below the portion that becomes the seating surface of the toilet seat, and is connected to the upper end of the inner wall of the toilet bowl at the lower end portion of the hollow portion, and this hollow portion is connected to the ball portion. It can also be used as a conduit for supplying cleaning water.
[0019]
In this way, the hollow portion itself can be made common regardless of the peripheral appearance of the toilet bowl. Therefore, there are the following advantages.
The hollow portion of the rim (rim hollow portion) can be used as a water conduit (so-called rim conduit) for supplying cleaning water to the ball portion from its upper edge. Therefore, even if it is in the water supply function which this rim waterway shows, it can be standardized in the toilet bowl of various external appearance designs. As a result, simplification of toilet bowl design and shortening of the design period can be promoted in combination with standardization of the cleaning function exhibited by the ball portion.
[0036]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described based on examples. First, the toilet bowl of an Example is demonstrated, and a manufacturing procedure is demonstrated after that. FIG. 1 is an explanatory view showing a toilet 10 manufactured in the present embodiment in a cross-sectional view at a substantially center thereof, and FIG. 2 is an explanatory view showing a toilet 100 having a peripheral appearance shape different from that of the toilet 10 in a cross-sectional view at a substantially center thereof. FIG.
[0037]
As illustrated, the toilet 10 surrounds a toilet inner surface wall 30 that forms a ball portion TB with an outer wall 20 that forms the peripheral appearance of the toilet, and the first inner / outer wall connecting portion 40 connects the outer wall 20 and the toilet inner wall 30. Connect through. The toilet inner wall 30 is also connected to the outer wall 20 by a second inner / outer wall connecting portion 48 extending from the bottom surface side of the outer wall 20.
[0038]
The toilet bowl 10 surrounds the upper edge of the ball portion TB with the rim 50, and the defecation opening 58 of the rim 50 faces the ball portion TB. The rim 50 is connected to the upper end of the toilet inner wall 30 on the ball portion side via a first rim connecting portion 51, and on the outer wall 20 side, the rim surrounding wall at the upper end portion of the outer wall 20 surrounding the rim 50. The external wall 20 is connected to and supported by the wall 22. In this case, the rim surrounding wall 22 is joined and connected to the lower surface of the end of the second rim connecting portion 52 extending from the rim 50.
[0039]
Even in the toilet 100, as in the case of the toilet 10, the outer wall 130 is surrounded by the outer wall 120 that forms the outer appearance of the toilet, and the outer wall 120 and the inner wall 130 are connected to the first inner / outer wall connecting portion. 140 and the second inner / outer wall connecting portion 148. Further, the toilet 100 connects the rim 150 surrounding the upper edge of the ball portion TB to the upper end of the toilet inner wall 130 via the first rim connecting portion 151 on the ball portion side, and surrounds the rim on the outer wall 120 side. The wall 122 and the second rim connecting portion 152 are connected to the exterior wall 120.
[0040]
Although both toilets are different in the toilet peripheral appearance exhibited by the exterior wall 20 and the toilet peripheral exterior exhibited by the exterior wall 120, the rim and the toilet inner wall are common as described in detail below.
[0041]
The opening for defecation facing the ball portion TB is standardized from the use of defecation regardless of the peripheral appearance of the toilet. Therefore, in this embodiment, the defecation opening 58 of the rim 50 and the defecation opening 158 of the rim 150 have substantially the same shape. The term “substantially” as used herein means that the shape is exactly the same and that the shape should be approximated for use as a defecation. Therefore, since the defecation opening is generally circular or oval, the defecation opening 58 and the defecation opening 158 may be used if there is no difference in the function of defecation even if there is a difference in the circular shape or oval shape. Can be said to be substantially the same.
[0042]
In addition, the rim 50 includes a hollow portion 54 below a seating portion 53 that serves as a seating surface of the toilet seat, and includes a hollow portion 154 even in the rim 150. Both the hollow portions have the same shape. In this case, the same hollow part shape includes differences that occur due to shrinkage in manufacturing such as mold forming and subsequent firing, and is substantially the same in the mold shape of the mold used for rim molding. Means.
[0043]
As illustrated, in the toilet 10, the first inner / outer wall connecting portion 40 is short, and in the toilet 100, the first inner / outer wall connecting portion 140 is long. That is, in the toilet bowl 100, since the exterior wall 120 is widened in accordance with the peripheral appearance of the toilet bowl, the toilet inner wall 130 is connected by the long first inner / outer wall connecting portion 140. However, in the toilet 10, since the external wall 20 and the toilet inner wall 30 are located relatively close to each other, the first inner and outer wall connecting portions 40 are connected to each other. In this way, in the toilet bowl 10 and the toilet bowl 100, the toilet inner wall 30 and the toilet inner wall 130 are made common so that the ball portion TB formed by them has a common ball shape. The meaning of the common use of the ball portion TB and the toilet inner wall in this case means that the shape of the mold used for manufacturing these is substantially the same as in the case of the rim.
[0044]
Since the toilet inner walls 30, 130 are thus shared, the first rim connecting portions 51, 151 that connect the rims 50, 150 to the toilet inner walls 30, 130 are the same in the toilet 10 and the toilet 100. The shape is the same. In this case, even if the first rim connecting portion has the same shape, as described above, it means that the shape of the molding die used for manufacturing these is substantially the same, and the inside of the toilet in each toilet The first rim connecting portion may be joined to the upper end of the surface wall.
[0045]
In the toilet 10, the second rim connecting portion 52 is shortened, and in the toilet 100, the second rim connecting portion 152 is lengthened, and the outer wall and the rim are connected to each toilet.
[0046]
In the toilet 10 and the toilet 100 configured as described above, even if the peripheral appearances of the toilets are different as shown in the drawing, the appearance change can be performed only by changing the shapes of the appearance walls 20 and 120 and the rim surrounding walls 22 and 122. I can deal with it. In addition, with the change in the appearance wall, in the toilet 10 and the toilet 100, the first inner / outer wall connecting portion 40 and the first inner / outer wall connecting portion 140, the second rim connecting portion 52 and the second rim connecting portion 152 are described above. What is necessary is just to change the length and shape. Therefore, in both toilet bowls of the present embodiment, when changing the peripheral appearance of the toilet bowl, the toilet inner wall is made common as described above, and the shape of the ball portion formed can be made common.
[0047]
In addition, for each rim 50, 150, in combination with the fact that the toilet inner wall 30, 130 is shared regardless of the peripheral appearance of the toilet bowl, the second rim connecting portion is adapted to the change of the peripheral appearance of the toilet bowl. It is sufficient to change 52 and 152. In the rims 50 and 150, the hollow portions 54 and 154 below the seating region 53 have the same shape.
[0048]
As described above, according to the present embodiment, since the toilet inner wall 30, 130 is pulled and the shape of the ball portion to be formed is made common, even if the toilet bowl has a wide variety of appearance designs, It is possible to standardize the cleaning function such as the state of accumulated water in the ball portion TB and the behavior of the cleaning water in the ball portion TB when the cleaning water is supplied to the ball portion TB. For this reason, in the production of a new toilet, such a cleaning function design is not required. Therefore, it is preferable to design an external design, a water supply design to the ball portion, and the like, which is simple. In addition, the toilet design period and manufacturing period can be shortened.
[0049]
Further, in making a toilet bowl having a wide variety of peripheral appearances, the shape change of the external walls 20, 120, the shape change of the rim surrounding walls 22, 122, the length change of the inner and outer wall connecting portions 40, 140, the second rim connecting portion It is only necessary to change the lengths of 52 and 152. Therefore, the freedom degree of the toilet bowl design including the surrounding external appearance of a toilet bowl can be raised.
[0050]
Furthermore, in this embodiment, the toilet inner wall 30, 130 is connected to the external wall 20, 120 at two locations, the first inner / outer wall connecting portion 40, 140 and the second inner / outer wall connecting portion 48, 148. Therefore, the toilet inner wall 30, 130 can be firmly fixed, and the stability is excellent. In this case, the second inner and outer wall connecting portions 48 and 148 may be omitted, and the toilet inner wall 30 and 130 may be connected to the appearance walls 20 and 120 by the first inner and outer wall connecting portions 40 and 140. . In this way, both the outer wall and the toilet inner wall can be molded by the so-called single molding method that requires only the mud deposition on the mold surface of the ball middle mold and the left and right molds, so that the bottom mold is unnecessary. Cost reduction can be achieved through simplification of the manufacturing process and simplification of the manufacturing process.
[0051]
In addition, the rims 50 and 150 are connected to the upper ends of the rim surrounding walls 22 and 122 by second rim connecting portions 52 and 152 extending from the respective seating portions 53 and 153 to the toilet periphery side. For this reason, since a level | step difference is not left on a toilet seat seating surface, the improvement of appearance can be aimed at. In particular, in this embodiment, since the connection between the rims 50 and 150 and the upper end of the rim surrounding wall is a corner on the outer periphery of the rim, the appearance is further improved.
[0052]
Further, in this embodiment, the hollow portions 54 and 154 included in the rims 50 and 150 are made common while the peripheral appearance of the toilet bowl is different. Therefore, when the hollow portions 54 and 154 are used as the rim conduit for supplying cleaning water from the upper edge to the ball portion TB, the water supply function exhibited by the rim conduit (for example, the flow of cleaning water in the rim conduit) ) Can also be standardized in toilet bowls with a wide variety of exterior designs. As a result, in combination with the standardization of the cleaning function exhibited by the ball part TB, simplification of toilet design and shortening of the design period can be further promoted.
[0053]
Next, the manufacturing procedure of the toilet bowls 10 and 100 of the above-described embodiment will be described. 3 is an explanatory view showing a state in which the respective molds used for manufacturing the toilet 10 are combined, FIG. 4 is an explanatory view showing a state in which the respective molds used for manufacturing the rim 50 are combined, and FIG. FIG. 6 is an explanatory view showing a state in which the respective molds used for manufacturing are mold-matched. FIG.
[0054]
As shown in these drawings, in order to manufacture the toilet 10, first, the ball middle mold 60, the side molds 62 and 63 located on the left and right of the mold, the bottom mold 64, the rim upper mold 65, and the rim lower mold 66 are used. Prepare. Each of these molds is a porous mold, and slurry is efficiently deposited on the mold surface by suction from the mold side.
[0055]
The ball middle mold 60 is provided with a convex part 60a having a convex mold surface adapted to the inner wall shape of the toilet inner wall 30 forming the ball part TB, and has a mold end part 60c around the convex base part. The convex portion 60a has a standardized convex shape regardless of the mold surface shape of the side molds 62 and 63, and the convex portion 160a of the ball middle mold 160 used for manufacturing the toilet 100 and its mold surface shape are described above. Are identical.
[0056]
The left and right side molds 62 and 63 include mold surfaces 62a and 63a adapted to the outer wall shape of the rim surrounding wall 22 and the exterior wall 20 following the rim surrounding wall 22, and surround the ball middle mold 60 from the left and right. The bottom mold 64 includes a concave mold surface concave portion 64a that matches the convex portion 60a of the ball middle mold 60, and has a mold end portion 64b around the concave portion.
[0057]
The ball middle mold 60 has a mold end 60 c as an upper positioning part in the drawing of the left and right side molds 62 and 63, and the bottom mold 64 has a lower positioning part in the left and right side molds 62 and 63. Therefore, when these molds are combined, the left and right side molds 62 and 63 are vertically positioned so that each mold forms a stable cavity every time the toilet bowl is manufactured (toilet bowl side body formation) as follows.
[0058]
The ball middle mold 60 and the side molds 62 and 63 form a cavity for forming the rim surrounding wall substrate 22k with the mold surface of the side mold facing the convex base 60b. The side molds 62 and 63 form cavities for forming the exterior wall substrate 20k on the remaining mold surfaces through mud deposition. The ball middle mold 60 forms a cavity for forming the first inner / outer wall connecting portion base 40k on the shoulder mold surface 60d of the convex base 60b through mud deposition, and the convex 60a in the concave 64a of the bottom mold 64. A cavity for forming the bottom region of the toilet inner wall base 30k is formed with the front end facing each other. Further, the ball middle mold 60 forms a cavity for forming the remaining toilet inner wall 30k through the slurry deposition on the mold surface of the projection 60a up to the projection base 60b. In addition to the cavity for forming the bottom region of the toilet inner surface wall substrate 30k described above, the bottom mold 64 forms the second inner / outer wall connecting portion substrate 48k on the mold surface from the top to the side wall of the recess 64a through mud deposition. Forming a cavity.
[0059]
Among these cavities, in this embodiment, the cavities facing the mold surfaces to form the bottom regions of the rim surrounding wall substrate 22k and the toilet inner wall substrate 30k cause mud accumulation from the respective mold surfaces. The double molding to be formed is used, and the other cavities are single-molded to form a substrate through mud deposition on one mold surface. In addition, about the bottom mold | type 64, since the base material to form is the 2nd inner-outer-wall connection part base material 48k, and it cannot see from the exterior, the base material of shapes other than illustration can also be formed. Further, as described above, when the second inner / outer wall connecting portion 48 is omitted, there is no need to use the bottom mold 64, so that the mold structure / manufacturing process is simplified by the amount that the mold is not required. This can contribute to cost reduction.
[0060]
When the above-described cavities are formed by matching the ball middle mold 60, the side molds 62 and 63, and the bottom mold 64, slurry is poured into the cavities, air is sucked from the mold surface, and left for a predetermined time. This causes mud accumulation on the mold surface. After that, the mud drainage from the cavity and the sedimented mud are ground and the mold is removed. In this way, the toilet wall body 20k surrounds the toilet inner wall wall base 30k, and the toilet wall base 20k is connected to the toilet inner wall wall base 30k via the first inner / outer wall connecting portion base 40k. In this toilet body, the toilet inner wall base 30k is already connected to the exterior wall base 20k via the second inner / outer wall connecting portion base 48k.
[0061]
As shown in FIG. 4, the rim upper mold 65 includes a convex part 65 a having a convex mold surface adapted to the shape of the inner wall of the defecation opening 58, and has a recess 65 b around the convex base. The shape of the recess 65b is adapted to the shape of the seating portion base 53k of the rim base 50k and the second rim connecting part base 52k. The lower rim mold 66 has a mold surface adapted to the shape of the lower end side of the defecation opening 58 and the rim substrate 50k. When the upper and lower rim molds are aligned as shown in FIG. 4, they are positioned by pins or the like (not shown), and each mold is connected to the rim base 50k and the base every time the toilet is manufactured (rim base formation). The cavity for forming the second rim connecting portion base 52k and the first rim connecting portion base 51k is stably formed.
[0062]
After the formation of such cavities, mud is poured into each cavity, the mud-containing water is sucked from the mold surface, and left for a predetermined time, and mud deposits are caused on the mold surface of each mold. After that, the mud drainage from the cavity and the sedimented mud are ground and the mold is removed. By doing so, the rim base 50k is obtained in which the second rim connecting portion base 52k is continuous with the seating portion base 53k in the toilet peripheral direction and the first rim connecting portion base 51k is connected to the lower end side.
[0063]
When the rim base 50k and the toilet body base are thus obtained, the second rim connecting portion base 52k and the rim surrounding wall base 22k upper end, and the first rim connecting portion base 51k lower end and the toilet inner wall base 30k upper end are connected to the base. Each of these sludges is interposed by application or the like. In this state, the second rim connecting portion base 52k of the rim base 50k is joined to the upper end of the rim surrounding wall base 22k, and the first rim connecting portion base 51k of the rim base 50k is joined to the upper end of the toilet inner wall base 30k. . Thereafter, the bonded rim substrate 50k and the toilet body substrate are dried, and the substrate is fired. Thereby, the toilet bowl 10 shown in FIG. 1 is completed.
[0064]
The production of the toilet 100 is the same as that of the toilet 10, and porous types such as a ball middle mold 160, side molds 162 and 163, a bottom mold 164, a rim upper mold 165, and a lower rim mold 166 are prepared.
[0065]
Similar to the ball middle mold 60, the ball middle mold 160 includes standardized convex portions 160 a, and the periphery of the convex base is defined as a mold end portion 160 c for positioning the left and right side molds 162 and 163. The left and right side molds 162 and 163 are mold surfaces 162a and 163a in which the outer wall 120 is wider than the outer wall 20 of the toilet 10, as compared with the side molds 62 and 63. Similar to the bottom mold 64, the bottom mold 164 includes a concave mold surface 164a that matches the convex section 160a, and the periphery of the concave section serves as a mold end section 164b for positioning the left and right side molds 162 and 163. Even in each of these molds, a stable cavity is formed in the same manner as in the case of the toilet 10, every time the toilet is manufactured (toilet side base is formed).
[0066]
Even in the toilet bowl 100, as in the case of the toilet bowl 10, the ball middle mold 160 and the side molds 162 and 163 have a convex portion 160a, a convex base portion 160b, a shoulder mold surface 160d, and mold surfaces 162a and 163b. A cavity for forming the surrounding wall substrate 122k, a cavity for forming the exterior wall substrate 120k, and a cavity for forming the first inner / outer wall connecting portion substrate 140k are formed. In addition, a cavity for the toilet inner surface wall substrate 30k and a cavity for the second inner / outer wall connecting portion substrate 148k are formed through the bottom mold 164. Among these cavities, the mold surface shape of the mold to be used differs between the cavity for forming the rim surrounding wall substrate 122k, the cavity for forming the exterior wall substrate 120k, and the cavity for forming the first inner / outer wall connecting portion substrate 140k. Therefore, unlike the toilet bowl 10, the cavity for the toilet inner wall base 30k is the same as the toilet bowl 10.
[0067]
When the respective cavities described above are formed by matching the molds of the respective molds, the slurry is poured into the cavities, air is sucked into the cavities, and left for a predetermined time, as in the case of the toilet 10, and the mud is applied to the mold surfaces of the respective molds. Causes deposition. After that, the mud drainage from the cavity and the sedimented mud are ground and the mold is removed. By doing so, the exterior wall substrate 120k surrounds the toilet inner wall substrate 130k, and the exterior wall substrate 120k is inside the toilet through the first inner / outer wall connection portion substrate 140k longer than the first inner / outer wall connection portion substrate 40k of the toilet 10. A toilet bowl connected to the face wall base 130k is obtained.
[0068]
As shown in FIG. 6, the rim upper mold 165 includes a convex portion 165 a that is the same as the convex portion 65 a in the case of the toilet bowl 10, and the periphery of the convex portion base is formed with a seating portion base 153 k of the rim base 150 k and the first part 153 k. The recess 165b is adapted to the shape of the 2-rim connecting portion base 152k. The lower rim mold 166 has a mold surface adapted to the shape of the lower end side of the defecation opening 158 and the rim substrate 150k. When the upper and lower rim molds are aligned as shown in FIG. 6, they are positioned by pins or the like (not shown), and each mold is placed on the rim base 150k and the base every time a toilet is manufactured (rim base formation). Cavities for forming the connected second rim connecting portion base 152k and first rim connecting portion base 151k are stably formed. In this case, in the cavity for forming the first rim connecting portion base 151k, the shape and position thereof are the same as in the case of the toilet 10.
[0069]
After the formation of such cavities, as in the case of the toilet 10, mud flow into the cavities, suction of mud-containing water from the mold surface, and standing for a predetermined period of time cause mud deposition on the mold surfaces of each mold. After that, the mud drainage from the cavity and the sedimented mud are ground and the mold is removed. By doing so, the rim base 150k is obtained in which the second rim connecting portion base 152k is continuous with the seating portion base 153k in the toilet peripheral direction and the first rim connecting portion base 151k is connected to the lower end side. In the rim substrate 150k, the upper and lower mold surfaces are the same as in the case of the toilet 10, so that the hollow portion 154 is the same as the hollow portion 54 of the toilet 10.
[0070]
When the rim base 150k and the toilet body base are thus obtained, as in the case of the toilet 10, the lower surface of the second rim connecting portion base 152k, the upper end of the rim surrounding wall base 122k, the lower end of the first rim connecting portion base 151k, and the toilet inner wall surface base. The substrates are joined to each other through a slurry for connecting the substrates to the upper end of 130k. Thereafter, the bonded rim substrate 150k and the toilet body substrate are dried, and the substrate is fired. Thereby, the toilet 100 shown in FIG. 2 is completed.
[0071]
As described above, according to the manufacturing method of the present embodiment using the respective molds shown in FIGS. 3 to 6, the peripheral appearance of the toilet bowl is formed by the exterior walls 20 and 120 and the rim surrounding walls 22 and 122.

When the rim 50 is connected to the exterior wall 20 of the toilet bowl 10 and the toilet inner wall 30 via the first rim connecting portion 51 and the second rim connecting portion 52, the rim base is defined as a rim base 150k of the rim 150.
[0101]
In this rim substrate 150k, the second rim connecting portion substrate 152k exceeds the rim surrounding wall 22 of the exterior wall 20, so that the excess substrate is removed and used as the rim 50. In this way, when the rim 50 and the upper end of the rim surrounding wall 22 are connected to each other at the corner of the outer periphery of the rim, the corner shape can be easily molded while removing the second second rim connecting portion base 152k. For this reason, a toilet with improved appearance can be easily manufactured. Further, there is an advantage that the rim shape can be unified including the rim connecting portion.
[0102]
In addition, as in the case of the ball middle mold 60 and the ball middle mold 160, the following can be used to make the mold surface shape common. The toilet 10 in FIG. 1 described above is a rim water supply-type toilet that uses the hollow portion 54 of the rim 50 as a rim conduit to supply cleaning water to the ball portion TB, and the toilet 10F in FIG. It is a rim shot type toilet that ejects washing water from a washing water outlet 70. As described above, since various types of water supply can be employed in the toilet bowl, the rim water supply type toilet bowl has the same shape of the ball portion TB regardless of its appearance design, and the rim shot type toilet bowl also has an exterior design in such a toilet bowl. Regardless of this, the shape of the ball portion TB is made common. That is, the bowl part TB may be made common between toilets of the same water supply type, and the bowl part TB may have a different shape between toilets with different water supply types.
