Description

[0001] The present invention relates to a manufacturing process for a toilet ceramic and to a toilet ceramic produced by the process.

[0002] Toilet bowls for toilets or shower toilets are often manufactured using ceramic casting processes. More complex geometries of toilet bowls are often only achievable with comparatively high costs, especially for toilet bowls with optimized water flow.

[0003] The present invention is therefore based on the objective of providing an improved method for the production of toilet ceramics.

[0004] According to the invention, this problem is solved by a manufacturing process for a toilet ceramic with an inlet channel for flushing water adjacent to an outer wall surface of the toilet ceramic, wherein the manufacturing process comprises the following sequence: d) Filling a casting chamber formed by a multi-part mold with a filling slurry; f) Opening a first side wall mold part of the multi-part mold after a shard formation time has elapsed; g) Removing a molded body from the inlet channel, which is at least partially undercut with respect to a main demolding direction of the first side wall mold part; h) Inserting a lid-like garnish piece into an outer wall opening of the toilet ceramic remaining after removal of the molded body from the inlet channel; and i) Bonding the lid-like garnish piece to an outer wall surface of the toilet ceramic by means of a garnish slurry.

[0005] In simplified terms, an outer wall opening required for the production of the undercut inlet channel is closed with the lid-like trim piece, and the lid-like trim piece is then bonded to the outer wall surface. This makes it possible to easily form the inlet channel, at least partially undercut, with the side wall molding, for example without additional (filling) slides, which can be advantageous in terms of tooling costs and mold maintenance.

[0006] In summary, a relatively simple mold can be used to produce the sectioned, undercut inlet channel, without the need for additional slides. Furthermore, by attaching the lid-like trim piece to the outer wall, any existing transition between the trim piece and the outer surface of the toilet bowl (e.g., a visually and / or tactilely noticeable line in the transition area) can be positioned in a secondary viewing area or in an area not visible to the user during normal use. This can, for example, improve the overall visual appearance of the toilet bowl for the user and reduce the manufacturing effort required to create the transition between the trim piece and the outer surface.

[0007] Preferably, the garnishing slip differs from the filling slip. For example, the garnishing slip contains additional additives compared to the filling slip, which increases its initial adhesive strength and thus allows the lid-like garnishing piece to be held to the outer surface of the toilet bowl. The filling slip is, for example, a ceramic suspension that is poured into plaster molds to produce the toilet bowl. The slip can contain, for example, kaolin, quartz, feldspar, and / or a suspension thereof, and common garnishing or filling slips for the production of toilet bowls are known to those skilled in the art.

[0008] According to a preferred embodiment, the manufacturing process prior to step d) further comprises the following steps (in the following order): a) Providing a multi-part mold, the mold comprising at least one back wall mold part, two side wall mold parts and one bowl mold part; b) Inserting the mold body into the first of the two side wall mold parts such that an inlet channel for rinsing water formed by the mold body is at least partially undercut with respect to a principal demolding direction of the first side wall mold part; and c) Closing the mold.

[0009] The multi-part mold comprises at least the back wall mold, the two side wall molds, and the bowl mold; preferably, the multi-part mold consists only of these. The two side wall molds and the back wall mold are provided in such a way that they form the outer wall, including the rear mounting surface of the toilet bowl. The bowl mold, on the other hand, is designed to form an inner wall surface of the toilet bowl, extending from the upper edge of the toilet bowl to the wastewater outlet channel, which typically emerges at the lowest point of the inner wall surface. The two side wall molds and the back wall mold are, for example, provided on the same plane, and the bowl mold is placed onto the provided side wall molds and the back wall mold from above.A cavity is formed between the individual mold parts of the multi-part casting mold, namely the casting space to be filled with the filling slurry.

[0010] The main demolding direction of each part of the multi-part mold refers to the direction of movement of that part during the demolding process. In other words, the main demolding direction is the direction in which each part of the multi-part mold can be moved away from the workpiece (i.e., the toilet ceramic) without being held back by an undercut.

[0011] Preferably, before closing the mold, at least one mold part is inserted into the first of the two side wall mold sections such that the inlet channel formed by the mold part (after the shard formation time has elapsed) is undercut with respect to the main demolding direction of the first side wall mold section. After inserting the mold part, the mold is closed and then (as explained above) the casting chamber is filled with the filling slurry.

[0012] According to a preferred embodiment, the manufacturing process also includes the following step: e) Holding the filling slurry in the closed mold until a resulting shard reaches an average wall thickness of at least 8 mm, preferably at least 10 mm, 12 mm or 14 mm (with possible upper limits, irrespective of this, of at most 20 mm, 18 mm or 16 mm).

[0013] The term "average wall thickness" here refers to the mean value of the material thickness of the respective wall surface measured over a certain outer or inner wall surface, i.e., its average thickness over this surface.

[0014] Preferably, after the shard formation time has elapsed, the filler slurry not required for shard formation is drained off. The shard formation time can depend, for example, on the material compositions used, the ambient temperatures, or the manufacturing process employed. In the context of this invention, the shard formation time refers to the period necessary to achieve a minimum average wall thickness of 8 mm (see above).

[0015] According to a preferred embodiment, after step e) and before step f), the bowl-shaped component on which the inner wall surface of the toilet bowl ceramic is formed is first removed. Thus, the bowl-shaped component is removed first, which can be advantageous, for example, with regard to accessibility to the first side wall component.

[0016] According to a preferred embodiment, an outer wall of the inlet channel is formed at least section by the lid-like garnish piece, which is bonded to the outer wall of the toilet ceramic in step i).

[0017] Put simply, the lid-like trim piece, which is bonded to the outer wall, forms part of the outer wall of the inlet channel. On the one hand, this allows for the creation of an inlet channel that is at least partially undercut, as already explained; on the other hand, it can also be advantageous with regard to optimizing the water flow dynamics within the inlet channel.

[0018] According to a preferred embodiment, the lid-like trim piece is convexly curved and is arranged in step h) on a convexly curved outer surface of the toilet bowl. The convexly curved, lid-like trim piece thus adjoins and extends the convex outer surface of the toilet bowl. This allows for a visually appealing overall appearance, and the convex shape can also be advantageous with regard to water flow in the channel (namely, along an inner surface of the lid-like trim piece).

[0019] According to a preferred embodiment, the lid-like garnish is arranged in step h) on a side of the toilet bowl facing a rear wall. The "side facing the rear wall" of the toilet bowl is understood to be that part of the outer wall surface which faces a rear wall (in the mounted state of the toilet bowl on a wall) with at least one component of a surface normal, usually the rear half of the bowl that is closer to the wall.

[0020] The placement of the lid-like trim piece in the area of ​​the rear half of the outer wall surface, i.e. in the area facing the back wall, can be advantageous for the visual appearance of the toilet ceramic, especially in the case of visible transitions between the lid-like trim piece and the outer wall surface of the toilet ceramic.

[0021] According to a preferred embodiment, the back wall molding, the two side wall moldings, and the bowl molding are made of gypsum. Due to its porosity, gypsum draws water from the filling slurry, thereby enabling the formation of the body at the interfaces of the mold and thus achieving a minimum strength of the toilet ceramic for the subsequent processing steps.

[0022] Alternatively, the back wall mold part, the two side wall mold parts, and the bowl mold part—i.e., the components of the preferably four-part mold—are made of a porous plastic material. The porous plastic material is designed to allow water contained in the slurry to escape from the casting chamber while retaining the non-aqueous components of the slurry. Preferably, after the shard formation time has elapsed and the (residual) fill slurry not required for shard formation has been drained, the casting chamber is pressurized with compressed air in such a way that the water-based components of the slurry escape through the porous layer structure of the mold parts, and the formed shard further solidifies.

[0023] The invention further relates to a toilet ceramic obtained by a manufacturing process according to one of the above aspects, wherein the toilet ceramic comprises: an outer wall, an inner wall and at least one edge area connecting the outer wall to the inner wall at the top; an inlet channel for flushing water that is at least partially undercut, with an inlet connection and an outlet, wherein the inlet connection is formed in a rear-wall mounting area of ​​the toilet ceramic on its outer wall and the outlet is formed in the inner wall of the toilet ceramic; and an outlet channel for wastewater, wherein an outer wall of the inlet channel is formed at least partially by a lid-like garnish piece which is bonded to the outer wall of the toilet ceramic.

[0024] The bonded connection between the lid-like trim piece and the outer surface of the toilet bowl can, for example, create a visually homogeneous overall appearance. Furthermore, the bonded connection between the trim piece and the toilet bowl body can also exhibit improved aerodynamic properties, for example at the transition between the trim piece and any internal surfaces of the inlet channel.

[0025] In a preferred embodiment, the lid-like trim piece is seamlessly integrated into the outer wall of the toilet bowl. The term "seamless" here refers to a transition between the outer surface of the toilet bowl and the lid-like trim piece that is indistinguishable to the human eye from a certain distance (e.g., 1 m) when viewed from the outside. Preferably, the transition between the outer surface of the toilet bowl and the lid-like trim piece is flush with the surface, meaning there is no offset in the width direction of the toilet bowl. Alternatively, although this is not preferred, the lid-like trim piece can also be mounted on the outer surface.

[0026] According to a preferred embodiment, the lid-like trim piece is set back laterally from an outer circumferential line of the toilet bowl when viewed from above. In other words, when looking down at the toilet bowl, the lid-like trim piece is concealed by the edge area, i.e., it is recessed behind it in the width direction.

[0027] In a preferred embodiment, the lid-like trim piece is convexly curved; preferably, the outer surface of the toilet bowl is also convexly curved in the area of ​​the lid-like trim piece. Preferably, the lid-like trim piece is arranged on a side of the toilet bowl facing the rear wall. In simplified terms, the lid-like trim piece is located in a rear area of ​​the toilet bowl, which is barely visible, or preferably not visible at all, from the front (when the toilet bowl is mounted on the wall). This makes it possible, particularly in the case of a convexly curved outer surface, to position any transitions between the lid-like trim piece and the outer surface of the toilet bowl outside the user's field of vision.

[0028] According to a preferred embodiment, the lid-like trim piece is made of a ceramic material used in toilet bowls. Using the same material for both the toilet bowl and the lid-like trim piece avoids uneven shrinkage in downstream processes and ensures a homogeneous overall visual appearance. Furthermore, the use of the ceramic material can also be advantageous with regard to acoustic properties, as, for example, a ceramic trim piece offers better damping properties for any flow noise compared to a plastic one.

[0029] According to a preferred embodiment, the outlet of the inlet channel opens into a cavity formed by the inner wall of the toilet bowl in such a way that flushing water entering the interior through the outlet is guided tangentially along the inner wall to the outlet channel. This tangential introduction of the flushing water contributes, for example, to an overall improved flushing effect, as the water flows in a spiral pattern along the inner surface of the toilet bowl, thereby ensuring even cleaning of the inner surface. Furthermore, any debris is reliably captured by this water flow and conveyed to the outlet channel.

[0030] Generally, within the context of this disclosure, terms such as "above," "side," etc. (as well as corresponding directional indications) are to be understood as referring to the toilet bowl's position when mounted on a wall. In this context, "front" means the end of the toilet bowl opposite the wall, and "back" means the area of ​​the toilet bowl closest to the wall. Terms such as "left" and "right" refer to a top view of the toilet bowl from the front, i.e., looking towards the back wall.

[0031] Specifications such as side wall surface area, rim area, or inner wall surface area are to be understood as referring to the installed state of the toilet bowl. For example, the upper rim area of ​​the toilet bowl forms the support surface for a toilet seat and lid, the outer surfaces are the side surfaces visible from the outside even when the lid is closed, and the inner surfaces are a receptacle for toilet waste, which is usually closed by the lid when not in use.

[0032] The invention will be explained in more detail below using exemplary embodiments, whereby the individual features within the scope of the dependent claims may also be essential to the invention in other combinations, and no distinction will be made in detail between the different claim categories.

[0033] In detail, it shows / show Figure 1 shows a section through a mold 6 after a shard formation time, Figure 2 shows a side view of the mold 6 (from the right), Figure 3 shows a section view through the mold 6 and a toilet ceramic 1, Figures 4a-4c show a top view of the toilet ceramic 1, Figures 5a-5c show a side view from a rear oblique angle of the toilet ceramic 1, and Figure 6 shows an exemplary sequence of the process for manufacturing the toilet ceramic 1.

[0034] Figure 1Figure 1 shows a cross-sectional view through a mold 6 (looking down at a toilet bowl 6). In the example shown, the mold 6 is divided into four parts: a back wall mold part 6.3, two side wall mold parts 6.1 and 6.2, and a bowl mold part 6.4. The mold 6 is made of clay in this example.

[0035] The mold 6 forms a casting chamber which is filled with a slip. At the contact surfaces between the clay of the mold 6 and the slip, a process called "sharding" occurs, i.e., the hardening of the slip. After the hardening time has elapsed, the mold 6 is opened and the at least partially solid toilet ceramic 1 is removed (see below for details).

[0036] To simplify the presentation, in Figure 1The toilet ceramic 1 is shown as a solid body (see hatched area between an outer wall surface 2 and an inner wall surface 3 of the toilet ceramic 1). However, preferably the remaining filling slurry is drained off after the shard formation time has elapsed, creating a cavity between the outer wall surface 2 and the inner wall surface 3. The toilet ceramic 1 is preferably hollow inside, which, however, is omitted for the sake of simplicity in the sectional view. Figure 1 not shown.

[0037] In the Figure 1In the depicted state, the sharding time has already elapsed, meaning that the toilet ceramic 1 is at least solid to the touch in the example shown. For better visibility, the upper mold part 6.4, on which an inner wall surface 3 of the toilet ceramic 1 is formed, is not shown. However, the other parts of the mold 6, namely the two side wall mold parts 6.1, 6.2 and the rear wall mold part 6.3, are visible in the sectional view shown (a top view of the toilet ceramic 1 from above).

[0038] The rear wall molding 6.3 is designed to form a rear wall connection surface for the toilet bowl 1, for example, to create an inlet connection 4.1 of an inlet channel 4 and an outlet connection (not shown) of an outlet channel 5. The side wall moldings 6.1 and 6.2 are designed to form a right (first side wall molding 6.1) and a left (second side wall molding 6.2) outer wall surface 2 of the toilet bowl 1, respectively.

[0039] In Figure 1 The main demolding directions of the side wall mold parts 6.1, 6.2 and the rear wall mold part 6.3 are shown by arrows as an example. In the example shown, these lie in one plane; for example, mold parts 6.1, 6.2, 6.3 are placed on a common base and are moved away from each other on this base when the mold 6 is opened.

[0040] As in Figure 1 As can be seen, the inlet channel 4 of the toilet ceramic is at least partially undercut, specifically in relation to the main demolding direction of the first side wall mold part 6.1 of the mold 6. To produce this undercut section of the inlet channel 4, a mold body 7 (see Figure 4a) before closing the mold 6, the part is inserted into the first side wall mold section 6.1 in such a way that, after filling the casting chamber with the filling slurry (see step d) in the following description of the process) and the shard formation time has elapsed (see step f)), the inlet channel 4, which is at least partially undercut, is formed. After removal of the mold body 7 (step g)), an outer wall opening remains in the outer wall surface 2, which is covered with a lid-like garnish piece 4.2 (see Figure 2 ) is closed.

[0041] Figure 2 Figure 1 shows a side view of mold 6 (from the right), whereby the first side wall mold part 6.1 is not shown in the side view for clarity. The side view shows the toilet ceramic 1, in which the outer wall opening created by the mold body 7 is closed with the lid-like trim piece 6.2.

[0042] Specifically, the lid-like garnish piece 6.2 was inserted into the outer wall opening (step h)) and bonded to the outer wall surface 2 using a garnish slip (step i)).

[0043] Figure 3 This shows an exemplary cross-section through the toilet bowl 1 parallel to its underlying wall mounting surface. Examples are shown in Figure 3 The main demolding directions of the two side wall mold parts 6.1, 6.2 and the boiler mold part 6.4 can again be seen.

[0044] Figures 4a-4c show again a top view of WC ceramic 1 (similar to Figure 1 Several molded parts inserted into the mold are shown here as examples (7.1-7.4).

[0045] Figure 4a Figure 6 shows the state of the mold 6 during step d) (see also step P6) in the following embodiment of the method). The two side wall mold parts 6.1, 6.2 and the rear wall mold part 6.3 are again visible. Furthermore, in Figure 4aSeveral molded parts 7.1-7.4 are shown (often also referred to as a "wedge"), by means of which the inlet channel 4 of the toilet ceramic 1 and a portion of the inner wall surface 3 of the toilet ceramic 1 are formed. In the example shown, the first molded part 7.1 is inserted into the first side wall molded part 6.1 of the mold in such a way that, after filling the casting chamber with the filling slurry (see step d or P4 in the following description of the process) and the completion of the shard formation time (see step f or P6), the inlet channel 4, which is at least partially undercut, is formed. A second molded part 7.2 and a third molded part 7.3 adjoin the first molded part 6.1 and are provided to form a tangential transition between the outlet 4.3 of the inlet channel 4 and the inner wall surface 3 of the toilet ceramic 1. A fourth molded body 7.4 is provided in the rear wall molded part 6.3 of the casting mold 6 to provide an inlet connection 4.1 to form in the inlet channel 4 for rinsing water.

[0046] Figure 4b shows an exploded view of mold 6 (again in a top-down section). In Figure 4b The side wall components 6.1, 6.2 and the rear wall component 6.3 are shown again. The molded parts 7.1-7.4 are also visible again.

[0047] Figure 4c Figure 1 shows an exemplary section through the toilet ceramic 1 (again in a sectional view from above) after inserting the lid-like garnish 4.2 into the outer wall opening of the toilet ceramic 1 (step h) or P10)) and opening the casting mold 6 (step P12)). Here, the fully formed inlet channel 4 can be seen again.

[0048] Figures 5a-5c The figures show, as an example, a side view of the toilet ceramic 1 (seen from a slanted rear view, each without mold 6) before the insertion of the lid-like garnish piece 4.2 (see Figure 5a ), after inserting the lid-like garnish piece 4.2 (see Figure 5b ) and after the material-bonded connection of the lid-like garnish piece 4.2 with the outer wall surface 2 of the WC ceramic 1 (see Figure 5c ). As in Figure 5c As can be seen, the lid-like garnish 4.2 is no longer visually distinguishable from the outer wall surface 2 of the WC ceramic 1 after the material-bonded connection with the outer wall surface 2.

[0049] Figure 6 This shows, by way of example, the process steps of the manufacturing process for toilet ceramic 1, namely in the following order: P1) a multi-part mold 6 is provided, wherein the mold 6 comprises at least one back wall mold part 6.3, two side wall mold parts 6.1, 6.2 and one bowl mold part 6.4, P2) a molded body 7 is inserted into the first of the two side wall molded parts 6.1 in such a way that an inlet channel 4 formed by the molded body 7 for rinsing water is at least partially undercut with respect to a main demolding direction of the first side wall molded part 6.1, P3) the mold 6 closed, P4) a casting chamber formed by a multi-part casting mold 6 is filled with a filling slurry, P5) The filling slurry in the closed casting mold 6 was held for a shard formation time, P6) A still liquid filling slurry was drained after the shard formation time had elapsed. P7) After a period of shard formation, the first side wall mold part 6.1 of the casting mold 6 is opened, P8) the boiler mold part 6.4 of the casting mold 6 removed, P9) the molded body 7 is removed from the inlet channel 4, which is at least partially undercut with respect to a main demolding direction of the first side wall molded part 6.1, P10) a lid-like garnish piece 4.2 is inserted into an outer wall opening of the WC ceramic 1 remaining after removal of the molded body 7 from the inlet channel 4, P11) the lid-like piece of yarn is bonded to an outer wall surface 2 of the toilet ceramic 1 by means of a garnishing slip, P12) the mold 6 opened, and P13) The toilet ceramic 1 was removed.
