Description

The invention relates to a toilet bowl made, in particular, of ceramic material containing a bowl rim and having a distribution hood open to the bottom, which is located in front of the inlet and which forms a deflecting wall. The rim of the bowl has a circumferential protruding part, which forms a peakless guide for water. The water guide is hydraulically connected to the distribution hood.

Such a toilet bowl is known, for example, from a published application for the grant of a British patent GB 2431937.

The invention also relates to a toilet having such a toilet bowl.

In the case of toilet bowls, the flushing operation has two functions. Firstly, flushing water flushes the fecal matter from the wall of the toilet bowl. Secondly, the water present in the toilet receptacle enters the sewer. To completely clean the inside of the toilet bowl, flushing water is distributed around the circumference of the toilet bowl, starting from the inlet, so that flushing water can drain down the inside wall of the toilet bowl into the receiver. For this purpose, the known toilet bowl, first mentioned, has a distribution hood which is located in front of the inlet on the rim of the bowl. The distribution hood forms a deflecting wall, which ensures the distribution of flushing water coming from the inlet in both directions around the circumference of the toilet bowl. The invention consists in preventing the occurrence of water splashes due to the presence of a protruding part that extends along the rim of the bowl and forms a peakless guide for water. In the case of a known toilet bowl, this cannot be reliably provided, and therefore, occasionally there are undesirable cases of splashes of flushing water.

The basis of the invention is the task of improving the design of the known toilet bowl in such a way as to improve protection against splashing out of the flushing water while maintaining the availability of the water guide sufficient to clean the bowl. The basis of the invention is also the task of creating a toilet containing such a toilet bowl.

In accordance with the invention, the aforementioned problem is solved by using a toilet bowl, including the features set forth in paragraph 1 of the claims, and, as for the toilet, using the object of paragraph 10 of the claims.

The invention is based on the idea of creating a toilet bowl made, in particular, of a ceramic material containing a bowl rim and containing a distribution hood open to the bottom. The distribution hood is located in front of the inlet of the bowl rim and forms a deflecting baffle. The rim of the bowl has a circumferential, in particular protruding portion extending around the entire circumference, which forms a peakless water guide. The water guide is hydraulically connected to the distribution hood. The toilet bowl according to the invention is characterized in that the protruding part has a horizontal first wall, which passes into the deflecting wall of the distribution peak. The rim of the bowl has a second wall that protrudes downward. The first and second walls define the boundaries of the hollow channel of the water guide, which is open to the side and to the bottom.

The invention has several advantages.

The invention provides improved protection against splashing out of the wash water due to the fact that the horizontal first wall of the protruding part passes into the deflecting partition of the distribution peak. As a result of this, a closed hydraulic connection is formed between the peakless water guide and the distribution hood so that the flushing water in the transition area between the water guide and the distribution peak cannot splash out of the toilet bowl. In addition, the flushing water in the region of the water guide, that is, after the distribution peak in the direction of flow, is firmly held in the toilet bowl because the first and second walls define the boundaries of the hollow channel, which, in particular due to the presence of the first horizontal wall, makes it possible to obtain an improved water guide, under which rinsing water directed along the rim of the bowl is held securely in the bowl. The hollow channel of the water guide formed between the first and second walls is open to the side and the bottom, which allows a simple way to clean the water guide. As a result of this, the advantages of a peakless water guide are retained and at the same time, protection against splashing out of rinsing water is improved.

It has been unexpectedly found that the design of the rim of the bowl according to the invention, which is open inward, is strong enough to absorb the forces created by the rim of the bowl during use of the toilet bowl. This is also possible when the rim of the bowl has a protruding portion extending around the entire circumference, formed by a horizontal first wall, which passes into the deflecting partition of the distribution peak.

To this it should be added that the design of the toilet bowl according to the invention brings a significant aesthetic effect. Compared to the known toilet bowl mentioned at the beginning, the toilet bowl according to the invention generally gives the impression of a light and streamlined shape, because the known massive protruding part is replaced by the first and second walls. In addition, the transition of the horizontal first wall to the deflecting partition of the distribution peak gives an unusual design to the toilet bowl, which attracts the eye of the person who is looking at it.

In another preferred embodiment, the wall extending downward is inclined inward. Due to this, on the one hand, an elegant shape of the toilet bowl is achieved, since the second wall limits the outer circumference of the bowl rim, and the location of the second wall with an inclined inward angle defines the boundary of the external contour of the toilet bowl. On the other hand, the inclined arrangement leads to a good transfer of forces from the rim of the bowl to the underlying area of the toilet bowl.

The water guide can be improved, for example, by means of a rim of a bowl having a circumferential ledge that delimits the hollow channel in a downward direction. The circumferential ledge also has an aesthetic effect because the rim of the bowl is offset from the lower region of the toilet bowl. In this case, the horizontal first wall protrudes further inward than the circumferential ledge, so that the channel is open to the bottom, and it becomes possible, on the one hand, to prevent the splash in the upward direction and, on the other hand, to ensure good drainage of water in the downward direction.

The first and second walls may have the same wall thickness. This facilitates the manufacture of a toilet bowl. And here, an aesthetic effect is additionally manifested, since the limited wall thickness of the two walls enhances the overall impression of a streamlined shape and lightness produced by the toilet bowl.

In the most preferred embodiment of the invention, the horizontal first wall smoothly passes into the distribution peak. This gives the technical advantage that the water is more efficiently directed inward, namely along the circumference of the bowl in the plane of the wall of the reflector, so that protection against splashing out of the wash water is improved. In addition, an aesthetic effect is achieved, with a smooth transition from the first wall to the distribution peak, giving the overall impression of harmony of the toilet bowl.

There is freedom of choice of design solutions for the transition between the first wall and the distribution peak. For example, a transition edge can be formed between the horizontal first wall and the distribution hood, so that in general the toilet bowl creates the effect of a more angular design.

Preferably, the distribution peak extends along a portion of the circumference of the rim of the bowl, which is 25% to 35% of the entire circumference. This provides a fairly reliable protection against splashing out of the wash water.

In the most preferred embodiment of the invention, the lower edge of the distribution peak is located at the same height as the inner edge of the toilet bowl in the area of the inlet, or above. Thanks to this arrangement of the lower edge, the efficiency of flushing the toilet bowl increases. The greatest effect is the location of the lower edge of the distribution peak above the inner edge of the toilet bowl in the area of the inlet. An increase in flushing efficiency is manifested in the fact that a larger part of the flow exiting through the inlet enters directly into the toilet bowl. As a result of this, the area of the toilet bowl that is located directly below the distribution peak is especially well cleaned. The wording “in the area of the inlet” means that the distribution hood covers the inlet at least partially, in particular completely. As for the geometry of the toilet bowl, the lower edge of the distribution peak in the region of the central longitudinal axis of the toilet bowl is located at the same height as the inner edge of the toilet bowl, or higher. The central longitudinal axis of the toilet bowl is the axis that passes through the middle of the toilet bowl in the longitudinal direction. The lower edge of the distribution peak is located symmetrically with respect to the central longitudinal axis.

In other words, the lowest point of the lower edge of the distribution canopy is located at the same height as the inner edge of the toilet bowl, or higher.

The aforementioned height position of the lower edge is disclosed and claimed in relation to the horizontal first wall, which smoothly passes into the distribution peak, and also in relation to the transition edge between the horizontal first wall and the distribution peak, and, moreover, regardless of the aforementioned transition.

in FIG. 9: shows a longitudinal section through a variant of the toilet bowl of FIG. one.

The toilet bowl of FIG. 1 is a floor-mounted toilet containing a base mounted on the floor. The invention may also relate to other types of toilets, for example to a hanging toilet, which has no base, but which is mounted in a known manner to the wall. The same applies to all embodiments of the invention described in this patent application. The invention relates, in general, to so-called flush toilets, in which the toilet receptacle is connected to an air trap to prevent the emission of foul odors (FIG. 4).

The detailed features described below are implemented in both examples of the embodiments of FIG. 1-4 and FIG. 5-8 and are described and disclosed with reference to both examples of embodiments. The differences between the examples of embodiments are in the transition from the horizontal wall 14 to the distribution hood 11, which will be explained separately.

As shown in all the figures, the toilet bowl has a rim 10 of the bowl, which limits the upper opening of the bowl. The rim 10 of the bowl goes into the surface 18 of the mount, which serves to secure the seat and lid of the toilet. For this purpose, appropriate mounting holes are provided. Optionally, a mounting area 19 is adjacent to the attachment surface 18, onto which a flush cistern can be mounted. The mounting area 19 is hydraulically connected to a flushing water source. Wall hung toilets are suitably modified.

As can be seen from FIG. 4 and 8, the toilet bowl has a central inlet 12, which is centrally located in the region of the rim 10 of the bowl. The outlet 20 is made in a well-known manner in the toilet receiver and contains an air lock. The bowl flush area 21 extends between the outlet 20 and the inlet 12. The image of the flush area 21 shown in FIG. 1-8 should be understood as given as an example. There is the possibility of another constructive implementation of this area, in particular in aesthetic aspects.

As clearly seen from FIG. 4 and 8, the rim 10 of the bowl has a distribution visor 11 open to the bottom. Originating from the upper edge of the rim 10 of the bowl, the distribution visor 11 protrudes inward into the bowl of the toilet bowl. The distribution hood 11 is located in front of the central inlet 12 and forms a deflecting baffle. Its purpose is to cause the washing water flowing out of the inlet 12 to deviate to either side in the circumferential direction of the bowl so as to rinse, as far as possible, the entire flush area 21 along the rim 10 of the bowl. The distribution hood 11 is open to the bottom so that a gap 22 is formed between the deflecting wall and the inner edge 23 of the bowl. During washing, a portion of the flushing water passes through the gap 22 and the toilet bowl enters, so that body excretions below the distribution peak 11 are washed off.

The inner edge 23 in the region of the distribution peak forms the extreme end of the flow space 24a, which forms part of the inlet 12. As can be seen from FIG. 4 and 8, the lower edge 25 of the distribution hood 11 is configured to be lower than the inner edge 23, so that the distribution hood 11 completely covers the inlet 12. This means that the flushing water coming from the inlet 12 is reliably directed down in the field of a distribution peak 11.

Surprisingly, it has been found that an alternative arrangement of the lower edge of the distribution visor improves the flushing efficiency. In the embodiment, as shown in the example embodiment of FIG. 9, the lower edge 25 of the distribution peak is located higher than the inner edge 23. As a result, the gap between the distribution peak 11 and the inner edge 23 is slightly larger, so that a larger volume of flushing water flows directly into the bowl below the distribution peak 11. If the lower edge 25 is located at the same height as the inner edge 23, or not more than 2 cm higher than the inner edge, in particular not more than 1 cm, in particular not more than 0.5 cm higher than the inner edge 23, manage to avoid you splashing of rinsing water, and at the same time rinsing efficiency increases. The position of the inner edge 23 and the lowest point of the lower edge 25 is measured from the same reference point, for example, from the floor level. In other words, the inner edge 23, for example, at the point where it intersects the central longitudinal axis, is located at a first distance from the floor level. The lower edge 25, where it likewise crosses the central longitudinal axis, is located at a second distance from the floor. The gap separating the lower edge 25 and the inner edge 23 from each other corresponds to the difference of the first and second distances.

The angle of inclination of the distribution peak 11 approximately corresponds to the angle of inclination of the toilet bowl below the distribution peak 11. In other words, the distribution peak and the wall of the toilet bowl below the distribution peak 11 extend substantially parallel to at least the upper region near the inner edge 23.

The position of the lower edge is shown in FIG. 9 in relation to a smoothly extending distributor visor 11. The position of the lower edge discussed above is also considered with reference to the examples of embodiments of FIG. 5-8.

Wash water, deflected in a circumferential direction in the area of the distribution peak 11, during flushing passes along the rim 10 of the bowl, and part of the wash water enters the bowl and rinses the flushing area 21. For this purpose, the rim 10 of the bowl has a circumferential, and in the case of examples of embodiments of FIG. 4 and 5, a completely circumferential protruding portion 13, which forms a peakless water guide. The water guide is peakless because there are no downward-facing structural elements in this area.

As shown in FIG. 4 and 8, the protruding portion 13 extends around the entire circumference. This means that the protruding part 13, and therefore also the water guide, extends along the entire circumference of the rim 10 of the bowl. The water guide has a hydraulic connection with the distribution peak 11. This means that the flushing water deflected by the distribution peak 11 passes into the water guide when flushing and from there it is distributed around the circumference of the bowl and enters the bowl.

It is now obvious that the protruding part 13, on the one hand, forms a peakless water guide outside the region of the distribution peak 11. On the other hand, the protruding part 13 forms the upper boundary of the toilet bowl in the region of the distribution peak. Therefore, the water guide and, therefore, the protruding part 13 are peakless in the regions, in particular in the region outside the distribution peak 11, as can be seen in all the figures. The peakless region of the toilet bowl is from 65% to 75% of the entire circumference.

As can be seen from the figures, the protruding portion 13 has a horizontal first wall 14. The horizontal first wall 14 extends radially inward and limits the rim 10 of the bowl in the upward direction. This is clearly seen from figures 4 and 8. The rim 10 of the bowl has another, second wall 15, which extends in a downward direction. The downward direction refers to the location occupied by the toilet during operation. The first and second walls 14, 15 are connected to each other at an angle and limit the hollow channel of the water guide, which is open to the side and to the bottom. In other words, two walls 14, 15 form an L-shaped angular profile part extending in the circumferential direction of the rim 10 of the bowl, with one shoulder of the angular profile part being horizontal (horizontal first wall 14). The angular profile part bends around the circumferential direction of the bowl.

The horizontal first wall 14 ends flush with the upper edge of the rim 10 of the bowl, as can be seen, in particular, in FIG. 4 and 8. The horizontal first wall, respectively, forms the upper surface of the toilet bowl. A rounding may be provided in the region of the inner edge of the first wall 14, which gives the rim of the bowl a pleasant appearance. The first wall 14 extends radially inward so that reliable protection against splashing out of the wash water is provided. For this purpose, it is sufficient that the wall width is from 2 cm to 6 cm. The second wall 15, which extends downward, has a slight inclination inward. Other orientations of the second wall are possible and their choice can be made essentially without restrictions by the designer. The rim 10 of the bowl has a circumferential ledge 16, which limits the hollow channel 24 in the downward direction. The ledge 16 runs parallel to the first wall 14 and causes the outward protrusion of the rim 10 of the bowl in the region of the water guide. On the one hand, as a result of this, good water direction is achieved. On the other hand, the protrusion of the rim 10 of the bowl affects the aesthetic impression, which generally produces the toilet bowl. And in this case, different layout options are also possible, depending on aesthetic or technical considerations.

In the case of the presented examples of embodiments, the first and second walls 14, 15 have the same wall thickness. In general, the wall thickness of the two walls 14, 15 corresponds to the wall thickness of the bowl in the washout region 21.

In contrast to the example embodiments of FIG. 5-8, the example embodiments of FIG. 1-4 has a smooth transition from the horizontal first wall 14 to the distribution peak 11. This is clearly seen in FIG. 1-4. For a smooth transition, the first wall 14 becomes wider, and the expanded part of the wall deviates from the horizontal plane and bends. In this case, the first wall smoothly passes into the deflecting partition wall of the distribution peak 11. This also applies to the inner edge of the second wall 15, which smoothly passes in the downward direction and passes into the distribution peak 11. As a result, on the one hand, the extension of the distribution peak 11 is achieved. in the circumferential direction so that the guiding effect is improved and, as a result of this, a more reliable protection against splashing out of the wash water is achieved. On the other hand, the shape of a gentle curve results in a particularly aesthetic shape.

As shown in FIG. 3, the distribution hood 11 and the smooth transition are symmetrical, so that the mentioned improvement is used in both circumferential directions. The angle of inclination smoothly passing in the downward direction of the inner edge of the first wall can be changed.

In the case of the example embodiments of FIG. 5-8, instead of a smooth transition, a transition edge 17 is provided, which is formed between the horizontal first wall 14 and the distribution peak 11. Because of this, there is a sharp transition from the distribution peak 11 to the first wall 14, due to which the overall impression of viewing the toilet is not such as in the case of the example embodiment of FIG. 1-4. From a technical point of view, the angular transition gives the advantage that it is possible to overlap the inner edge 23 with a distribution peak 11 along a longer subregion of the circle than in the case of the embodiment of FIG. 1-4.

In the case of both examples of embodiments, the distribution peak is positioned along a portion of the circumference of the rim 10 of the bowl, which ranges from 25% to 35% of the entire circumference.
