Abstract
Description
[Technical Field]
[0001] The disclosed embodiments relate to sanitary ware. [Background technology]
[0002] One example of sanitary ware is a flush toilet that has a bowl surface that receives waste and a rim that is connected to the upper edge of the bowl surface and forms a rim conduit that swirls flush water supplied to the bowl surface. In some cases, such flush toilets have the upper edge of the bowl surface and the rim bonded together (rim-to-body bonding) during manufacturing (see, for example, Patent Document 1). In this case, a space is formed that is surrounded by inner and outer walls along the peripheral shape of the rim, including the front side (see, for example, Patent Documents 2 and 3).
[0003] Conventionally, in sanitary ware such as flush toilets that have a space surrounded by inner and outer walls, when the ware is removed from the mold during production, water that remains inside the space, for example, that has seeped out of the slip during molding or that has seeped out of the plaster or resin mold, is drained out of the space by tilting the ware that has been removed from the mold, in other words, a draining process is performed to remove the water from the space.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-113519 [Patent Document 2] Japanese Patent Application Publication No. 2023-136453 [Patent Document 3] Japanese Patent Publication No. 2022-064619 Summary of the Invention [Problem to be solved by the invention]
[0005] However, with conventional sanitary ware, it can be difficult to tilt the ware during drainage work to stabilize the flow of water so that it drains from the cavity in the appropriate direction. In such cases, water from the cavity flows onto a molding surface, such as the bowl of a flush toilet, leaving traces of water on the molding surface, reducing productivity.
[0006] An object of one aspect of the embodiment is to provide sanitary ware that can improve productivity. [Means for solving the problem]
[0007] A sanitary ware according to one aspect of the embodiment is a sanitary ware having a space surrounded by an inner wall and an outer wall, and the space has a guide portion that guides water present inside the space to the outside of the space.
[0008] According to this configuration, when water present in the space needs to be drained out of the space during demolding of the sanitary ware during production, tilting the ware guides the water from the space out of the space via the guide section. This allows the draining process to be performed simply by tilting the ware. Furthermore, by guiding the water from the space through the guide section, it is possible to prevent the water from flowing onto a molding surface, such as a bowl, and leaving traces on the molding surface. This configuration thus facilitates the draining process and, by guiding the water from the space in a specific direction, prevents the water from affecting other parts of the ware. This improves productivity.
[0009] In the above-described sanitary ware, the guide portion has an inclined surface that is inclined toward a predetermined discharge direction of water present in the space portion.
[0010] With this configuration, when the pottery is tilted, the water in the cavity is guided along the inclined surface, making it less likely to flow to other parts of the pottery, thereby preventing the water from affecting other parts of the pottery.
[0011] In the above-described sanitary ware, the space has an expanded portion that expands in the width direction of the space on the downstream side in the discharge direction, and the guide portion is disposed in the expanded portion.
[0012] With this configuration, water in the space is discharged from the widened portion (expanded portion) in the width direction of the space, so that when the pottery is tilted, the water is prevented from concentrating in the guide portion, and for example, the water is prevented from overflowing from the space and flowing to other parts, thereby preventing the water from affecting other parts of the pottery.
[0013] In the above-described sanitary ware, the space has a water reservoir portion that is recessed from the surrounding area.
[0014] With this configuration, water is stored in the water reservoir, so when the pot is tilted, the water in the cavity tends to collect in the guide section. This keeps the flow of water constant when the pot is tilted, preventing it from flowing to other parts of the pot. This prevents the water from affecting other parts of the pot.
[0015] In the above sanitary ware, the water reservoir is disposed near the guide portion.
[0016] With this configuration, because water is stored in the water reservoir, when the pot is tilted, the water in the space tends to collect in the guide section near the water reservoir. This keeps the flow of water constant when the pot is tilted, preventing it from flowing to other parts of the pot. This prevents the water from affecting other parts of the pot.
[0017] Furthermore, in the above-mentioned sanitary ware, the sanitary ware is a flush toilet having a bowl surface that receives waste, and a rim portion that is connected to the upper edge of the bowl surface and forms a rim waterway that swirls the flush water supplied to the bowl surface, and the space portion extends from either the left or right side of the flush toilet across the front end of the rim portion to the other of the left or right sides, and is located on the other of the left or right sides.
[0018] With this configuration, the space extends from either the left or right side of the flush toilet across the front end of the rim to either the left or right side, and is located on either the left or right side, so that when the toilet is tilted, water in the space tends to collect in the guide section. This keeps the flow of water constant when the toilet is tilted, preventing it from flowing to other parts of the toilet. This prevents the water from affecting other parts of the toilet.
[0019] In addition, in the above-mentioned sanitary ware, the rim portion has a water outlet that discharges cleaning water supplied to the bowl surface, and the water outlet has a first water outlet located on either the left or right side of the rim portion, and a second water outlet located on the other either the left or right side of the rim portion and located rearward of the first water outlet.
[0020] With this configuration, when the flush toilet has a first water outlet located on either the left or right side of the rim, and a second water outlet located on the other of the left or right sides of the rim, the second water outlet is located behind the first water outlet, so it is possible to ensure space for forming a space in front of the second water outlet. And by ensuring space for the space, it is possible to easily provide a guide section to be placed inside this space.
[0021] In the above-described sanitary ware, of the two ends of the space in the predetermined discharge direction of water present in the space, the end on the second water outlet side is wider in the width direction of the space than the end on the first water outlet side.
[0022] With this configuration, the end of the space on the second spout side is wider in the width direction than the end on the first spout side, so when the pottery is tilted, water in the space tends to collect in the guide section. This makes the flow of water when the pottery is tilted almost constant, preventing it from flowing to other parts of the pottery. This prevents the water from affecting other parts of the pottery.

[0025] Hereinafter, embodiments of the sanitary ware disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described below.
[0026] <Overview of Sanitary Ceramic (Flush Toilet)> First, an overview of the sanitary ware 1 according to the embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic perspective view showing an example of the sanitary ware 1 according to the embodiment. In this embodiment, a ceramic flush toilet will be described as an example of the sanitary ware 1.
[0027] Each figure may also show a three-dimensional Cartesian coordinate system including a Z-axis, with the positive direction being the vertically upward (upward). In the following, for convenience of explanation, the positive direction of the X-axis is defined as the left, the negative direction of the X-axis as the right, the positive direction of the Y-axis as the forward direction, and the negative direction of the Y-axis as the backward direction, and the X-axis direction may also be referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction.
[0028] As shown in Figure 1, the sanitary ware flush toilet 1 is a so-called floor-standing flush toilet that is installed on the floor of a toilet room. However, the flush toilet 1 may also be a so-called wall-hung flush toilet that is installed on the wall of a toilet room.
[0029] Flush toilet 1 comprises a body portion 2, which forms the toilet body, and a rim portion 3. Body portion 2 comprises a bowl portion 21, a drain trap pipe line 22 (see Figure 2), and a skirt portion 23. Bowl portion 21 comprises a bowl surface 211. Bowl surface 211 is the portion of bowl portion 21 that receives waste. Bowl surface 211 is formed in a concave shape in bowl portion 21.
[0030] Drain trap pipe 22 is connected to bottom 211a (see FIG. 2) of bowl surface 211 on the upstream side in the flow direction of flush water supplied to bowl surface 211 of bowl portion 21. Drain trap pipe 22 extends downward and rearward from bottom 211a of bowl surface 211.
[0031] Furthermore, the downstream side of drain trap pipe 22 in the direction in which flush water flows is connected to external piping (not shown) via a drain socket (not shown). Drain trap pipe 22 discharges waste matter received on bowl surface 211 to the external piping by flush water discharged from water outlet 32 (see FIG. 2), which will be described later.
[0032] Skirt portion 23 is provided on the outside of bowl portion 21, for example, so as to surround the bowl portion 21 from either the left or right side, through the front, to the other left or right side. Such skirt portion 23 forms the front half of the outer surface of body portion 2. Note that the rear half of body portion 2 may be provided with, for example, a resin panel member that is detachable from body portion 2.
[0033] The rim section 3 is connected to the upper edge 211b (see Figure 2) of the bowl surface 211 of the bowl section 21. The rim section 3 has a portion formed in an annular shape along the upper edge 211b of the bowl surface 211. The rim section 3 comprises a portion (part of the rim water conduit 31) that forms the upper part of the rim water conduit 31 (see Figure 2), and a portion (part of the water conduit 31) that forms the upper part of the spout 32. The rim water conduit 31 is formed by bonding the body section 2 and the rim section 3 together.
[0034] Rim water conduit 31 supplies flush water supplied from a flush water tank or the like to outlet 32, which will be described later, which is the outlet for this flush water from rim water conduit 31. The flush water discharged from outlet 32 becomes a swirling flow that flows while swirling on the surface of bowl surface 211, cleaning the part of bowl section 21 to be washed, including bowl surface 211.
[0035] The water outlet 32 is formed by bonding the body portion 2 and the rim portion 3 together. The water outlet 32 discharges flush water to be supplied to the bowl surface 211. The water outlet 32 discharges flush water towards the bowl surface 211. The water outlet 32 comprises a first water outlet 321 (see Figures 3 and 4) and a second water outlet 322 (see Figures 3 and 4). The first water outlet 321 and the second water outlet 322 each discharge flush water onto the bowl surface 211 from different positions. The respective positions of the first water outlet 321 and the second water outlet 322 will be described later using Figure 4.
[0036] Sanitary ware is manufactured by preparing a slurry containing the raw materials for the ceramic base, forming a molded body using the slurry through casting, drying the molded body, applying a glaze to the dried molded body, and firing the glazed molded body.
[0037] For example, in the manufacturing process of sanitary ware, first, in a slip preparation step, a slip containing raw materials for the ceramic body is prepared. In this case, the slip contains a large amount of water and has low viscosity. Next, in a pouring step, the slip is poured into a mold. In such a case, a resin mold is used as the mold. Alternatively, a plaster mold or the like may be used as the mold.
[0038] Next, in the casting process, the water content of the slip is removed and the slip is cast onto the molding surface of the mold. Next, in the draining process, the uncast liquid slip is discharged. Next, in the demolding process, the molded body is removed from the mold. Next, in the joining process, the molded bodies of each portion (part) are bonded together to form the desired shape.
[0039] Next, in the drying step, the molded body is dried. Next, in the glazing step, a glaze is applied to the dried molded body. Then, in the firing step, the glazed molded body is fired at a temperature of 1000 to 1300°C.
[0040] When the ceramic ware is removed from the mold during production, any water remaining inside space 40 (described below), such as water that seeps out of the slip during molding or from a plaster or resin mold, is drained to the outside of space 40 by tilting the ware after it has been removed from the mold. In other words, when the sanitary ware is demolded, a draining process is carried out to drain the water from space 40. If the sanitary ware is a flush toilet 1, the angle at which the ware is tilted during the draining process is, for example, around 10 degrees, with horizontal being 0 degrees. Also, if the sanitary ware is a flush toilet 1, for example, the front of the ware is lifted and the water is drained toward the rear of the ware.
[0041] Figure 2 is an explanatory diagram of part of the manufacturing process for sanitary ware (flush toilet) 1 according to an embodiment. Figure 2 shows a schematic cross-sectional side view of a flush toilet 1, which is sanitary ware, and illustrates the process of joining the body 2 and rim 3 of the flush toilet 1.
[0042] As shown in Figure 2, when the sanitary ware is a flush toilet 1, the toilet body is formed by bonding a rim 3 from above to a body 2. The flush toilet 1 has a space 40 where the body 2 is bonded to the rim 3. The space 40 is a space formed by being surrounded by a bottom surface 46 (see Figure 3), which will be described later, of the space 40, and an inner wall 41 and an outer wall 42, which will be described later.
[0043] With a flush toilet 1, it can be difficult to tilt the toilet body (ceramic) during the draining process and stabilize the flow of water so that it is discharged from the space 40 in the appropriate direction. If the flow of water from the space 40 is not stable, the water may flow onto molding surfaces such as the bowl surface 211, leaving traces of the water on the molding surfaces, reducing productivity. In this embodiment, the space 40 is equipped with a guide section 43 that can keep the flow of water approximately constant when the toilet body is tilted.
[0044] <Space section> Next, the space 40 will be described with reference to Figures 3 to 9. Figure 3 is a schematic perspective view showing the body 2 of the sanitary ware (flush toilet) 1 according to the embodiment. Note that Figure 3 also shows an enlarged view of part A shown in the figure at the top of the figure. Figure 4 is a schematic plan view showing the body 2 of the sanitary ware (flush toilet) 1 according to the embodiment. Figure 5 is a cross-sectional view taken along line VV in Figure 4. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 4. Figure 7 is a cross-sectional view taken along line VII-VII in Figure 4. Figure 8 is a cross-sectional view taken along line VIII-VIII in Figure 4. Figure 9 is a cross-sectional view taken along line IX-IX in Figure 4.
[0045] As shown in Figures 3 and 4, space 40 is formed below rim portion 3 (see Figure 2). Space 40 is a space surrounded by inner wall 41 and outer wall 42, which support the bottom of rim portion 3 from below when rim portion 3 is adhered to body portion 2 of flush toilet 1.
[0046] Inner wall 41 is disposed on the inside, facing the center of bowl surface 211, when viewed from above and below. Outer wall 42 is disposed on the outside, facing away from the center than inner wall 41, when viewed from above and below.
[0047] As shown in Figures 3 to 9, the space 40 extends from either the left or right side of the flush toilet 1 (rim portion 3) to the other side, straddling the front end 33. In the example shown, the space 40 extends from the right side of the front end 33 of the flush toilet 1 (rim portion 3) to the left side, straddling the front end 33. The space 40 is also located on the other side of the flush toilet 1, either the left or right side. In the example shown, the space 40 is located on the right side of the flush toilet 1.
[0048] Here, as shown in Figures 3 and 4, the first water outlet 321 is positioned forward of the second water outlet 322 which is positioned at the rear of the rim section 3. As shown in Figure 3, the first water outlet 321 discharges flush water W from the rim water conduit 31 onto the bowl surface 211 at the rear of the rim section 3. The second water outlet 322 is positioned forward of the first water outlet 321 and discharges flush water W from the rim water conduit 31 onto the bowl surface 211. As shown in Figures 3 and 4, the space 40 is configured such that the water present in the space 40 flows in a predetermined discharge direction D W Of the two ends of the space 40, the end on the second water outlet 322 side is formed to be wider in the width direction of the space 40 than the end on the first water outlet 321 side. Note that the width direction of the space 40 is the direction D of water discharge in the space 40. W The portion of the space 40 that widens in the width direction becomes an expanded portion 44, which will be described later.
[0049] The space 40 includes a guide portion 43, an enlarged portion 44, and a water reservoir portion 45. The guide portion 43 guides water inside the space 40 to the outside of the space 40. As shown in FIGS. 3 to 5, the guide portion 43 has an inclined surface 431. The inclined surface 431 is inclined in the discharge direction D of the water inside the space 40. W That is, the water inside the space 40 is discharged in the direction D W is the direction toward the guiding section 43.
[0050] The guide portion 43 is arranged in the direction D of the water discharge in the space portion 40. W The downstream end of the two ends is disposed.
[0051] As shown in FIG. 5, the guide portion 43 is configured to guide the water in the space portion 40 in the direction D W The downstream end of the water discharge direction D W By providing the upright wall 432 at the downstream end, it is possible to ensure the rigidity of the connection between the inclined surface 431 and the upper surface of the body 2 (see FIG. 2) compared to a shape in which the inclined surface 431 continues up to the upper surface of the body 2. This makes it possible to stabilize the connection between the body 2 and the rim portion 3 (see FIG. 2).
[0052] As shown in FIGS. 3, 4, 7, and 8, the expansion portion 44 is formed in the space 40 in the direction D W The expanded portion 44 is formed downstream of the space 40. The expanded portion 44 is a portion that is wider in the width direction than other portions of the space 40. The width direction of the space 40 is the direction perpendicular to the water discharge direction D1 of the space 40. A guide portion 43 is arranged in the expanded portion 44.
[0053] The water pool 45 is a portion inside the space 40 where water tends to collect. In the water pool 45, the bottom surface 46 of the space 40 is recessed from the surrounding area so that the water in the space 40 can be concentrated. As shown in FIGS. 3 and 4, the water pool 45 is disposed near the guide portion 43. The water pool 45 is located in the water discharge direction D from the guide portion 43. W It is located upstream of the
[0054] As described above, according to the sanitary ware 1 of the embodiment, when removing the sanitary ware from the mold during production, if water present in the space 40 needs to be drained out of the space 40, tilting the sanitary ware guides the water from the space 40 out of the space 40 via the guide portion 43. Therefore, the draining process for draining water from the space 40 can be performed simply by tilting the sanitary ware. Furthermore, since the water in the space 40 is guided by the guide portion 43, it is possible to prevent the water from flowing onto a molding surface, such as the bowl surface 211, and leaving traces of the water on the molding surface. Thus, the sanitary ware 1 of the embodiment facilitates the draining process, and since the water in the space 40 can be guided in a specific direction, it is possible to prevent the water from affecting other parts of the sanitary ware. This improves productivity.
[0055] Furthermore, when the pottery is tilted, the water in the space 40 is guided along the inclined surface 431, and is therefore less likely to flow to other parts of the pottery. This makes it possible to prevent the water from affecting other parts of the pottery.
[0056] Furthermore, because the water in space 40 is discharged from the portion (expanded portion 44) that widens in the width direction of space 40, it is possible to prevent water from concentrating in guide portion 43 when the pottery is tilted, and it is possible to prevent water from overflowing from space 40 and flowing to other portions, for example. This makes it possible to prevent water from affecting other portions of the pottery.
[0057] Furthermore, because water is collected in the water collecting portion 45, the water in the space 40 tends to collect in the guide portion 43 when the pottery is tilted. This keeps the flow of water constant when the pottery is tilted, preventing it from flowing to other parts of the pottery. This prevents the water from affecting other parts of the pottery.
[0058] Furthermore, because water is collected in the water reservoir 45, when the pottery is tilted, the water in the space 40 tends to collect in the guide portion 43 near the water reservoir 45. Therefore, when the pottery is tilted, the flow of water remains approximately constant, preventing it from flowing to other parts of the pottery. This prevents the water from affecting other parts of the pottery.
[0059] Furthermore, because the space 40 extends from either the left or right side of the flush toilet 1 (rim 3) across the front end 33 to either the left or right side, and is located on either the left or right side, water in the space 40 tends to collect in the guide part 43 when the ceramic bowl is tilted. This keeps the flow of water approximately constant when the ceramic bowl is tilted, preventing it from flowing to other parts of the ceramic bowl. This prevents the water from affecting other parts of the ceramic bowl.
[0060] Furthermore, if the flush toilet 1 has a first water outlet 321 located on either the left or right side of the rim portion 3, and a second water outlet 322 located on the other of the left or right sides of the rim portion 3, the second water outlet 322 being located behind the first water outlet 321 makes it possible to ensure space for forming a space 40 in front of the second water outlet 322. And by ensuring space for the space 40, it is possible to easily provide a guide portion 43 to be placed inside this space 40.
[0061] Furthermore, because the end of space 40 on the second water outlet 322 side is wider in the width direction of space 40 than the end on the first water outlet 321 side, water in space 40 tends to collect in guide section 43 when the pottery is tilted. This keeps the flow of water constant when the pottery is tilted, preventing it from flowing to other parts of the pottery. This prevents the water from affecting other parts of the pottery.
[0062] In the above embodiment, the sanitary ware 1 is described as a flush toilet, but it is not limited to flush toilets and may be a ceramic urinal or washbasin, for example. Even when the sanitary ware 1 is a ceramic urinal or washbasin, the bonding area of the parts must have a space surrounded by inner and outer walls, just like the flush toilet described above.
[0063] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
