Description

Toilet
The invention relates to a toilet comprising a bowl the bottom portion of which comprises a drain, whereby a water channel which is open towards the bottom of the bowl is provided along the upper edge of the bowl, the water channel being adapted to distribute flushing water along the upper edge of the bowl to allow substantially the entire inner surface of the bowl to be flushed by the flushing water when the water flows downwards from the water channel, and means for supply¬ ing flushing water to the water channel, whereby the wall of the bowl forms the outer wall of the water channel, and a top separate from the bowl forms the top portion of the water channel and the inner wall of the water channel, said inner wall running substantially parallel with said outer wall spaced apart on the inside thereof, whereby at least the bowl is of a metal plate.
The invention concerns primarily a vandalism- proof toilet for use in public places, i.e. in places where a toilet can be subjected to vandalism. A conven¬ tional toilet made of porcelain is not suitable for such places, because it is much too easily damaged and broken. It is previously known to use toilets made of stainless steel or cast iron in public conveniences that can be vandalized. These toilets are either cast in one piece or alternatively manufactured of several separate plates of steel, for example, which are welded together. The most difficult problems with toilets made of cast iron are their weight and the high manufacturing costs. On account of the high manufacturing costs and the heavy weight, these toilets cannot be used, for example, in ships, where the weight is a significant factor and the number of toilets is large. The most serious problems with toilets made of stainless steel plates by welding are their appearance and the high manufacturing costs. In order to be as aesthetic as the corresponding toilets made of porcelain, the toilets of stainless steel must be surface-treated preferably by enamelling. Enamelling is, moreover, advisable for reasons of hygiene, since there is far more bacterial growth in a toilet made of steel plates than in a toilet made of porcelain or enamel. The main reason for this is that steel has a rougher surface. To facilitate the process of enamelling a toilet, one must perform the enamelling before the different parts of the toilet are connected to each other, otherwise it is impossible to surface-treat e.g. the water channel at the upper edge of the bowl in a sufficiently reliable manner. Enamelling of welded joints always involves the risk of porosity at the welded joints, which causes flaking. In addition, the welded joints must be smoothed down and surface-treated, otherwise the appearance of the toilet will suffer. This is laborious and increases the manufacturing costs of the toilet.
The object of the present invention is to solve the problem described above and to provide a durable and light toilet which is clearly more aesthetic than the known vandalism-proof toilets. This is achieved with a toilet according to the invention, which is character¬ ized in that the top is secured to the bowl with interlocking fixing means. The invention is based on the idea that when a toilet is made of two separate parts connected by screws, rivets or similar interlocking fixing means, the parts can be surface-treated separately, whereafter the surface-treated parts can be connected to each other. The invention thus provides a toilet which is clearly more aesthetic, cheaper to manufacture and lighter in weight than the known vandalism-proof toilets. If the top or the bowl of the toilet is nevertheless damaged, for instance by blows dealt from above, it is possible to replace only the damaged part rapidly and simply in si tu . If the toilet were assembled by e.g. welding, as the existing vandalism-proof toilets, such damages would make it necessary to replace the entire toilet.
When the top is secured to the toilet by screws, the flushing characteristics of the toilet can be adjusted in a very simple manner: the screw holes, for example, can be made slightly larger than necessary in view of the diameter of the fixing screws. The top can then be displaced with respect to the bowl when it is mounted on the bowl before tightening the screws. Since the top forms part of the flushing channel, the position of the top with respect to the bowl has a direct effect on the distribution of the water flow in the water channel, i.e. on the flushing characteristics. In the known toilets where the top is se ured to the bowl by welding, soldering or gluing, such an adjustment is, of course, not possible. If such manufacturing methods are used, the top must naturally be correctly positioned at one go, which makes the manufacture slower, as greater accuracy is required.
An advantage achieved with the toilet of the present invention is that the bowl and top of the toilet can be made of different materials. It is, for instance, possible to make the bowl of enamelled steel plates, whereas the top, with which the user of the toilet can in certain cases be in contact (if, for example, the seat is an integral part of the top) , can be made of e.g. ABS plastic. In this case, no separate seat portion is required, but the seat may be integrated with the top. Another advantage achieved with the toilet of the present invention is that since the top is a separate portion, it can be detached, whereby the upper edge of the bowl and the water channel located there can be thoroughly cleaned. Thereafter the top can be mounted again in its place or, if necessary, replaced with a corresponding new top.
The preferred embodiments of the toilet of the present invention are disclosed in the accompanying dependent claims 2 to 6. In the following, the invention will be described by means of a preferred embodiment and with reference to the accompanying drawings, in which
Figure 1 shows a preferred embodiment of a toilet according to the present invention, Figure 2 shows a cross-section of the toilet of Figure 1,
Figure 3 shows a cross-section of the water channel in the toilet, and
Figure 4 shows a cross-section of the water channel in the toilet according to another embodiment.
Figure 1 illustrates a preferred embodiment of the toilet of the present invention. The toilet shown in Figure 1 comprises a bowl 7, a top 3 mounted on the bowl, and a seat 2. The seat shown in Figure 1 comprises two separate portions 2 attached to the top 3. Alternatively, the seat and the top can made in one piece.
The toilet 1 of Figure 1 is intended to be mounted on a wall, i.e. the back plate 6 of the toilet is secured to a wall, whereby the toilet is suspended from the wall without touching the floor. The drain 4 of the toilet is in this case connected to a waste-pipe located in the wall, and the inlet opening in the toilet for flushing water is connected to a separate flush tank and the water pipes connected to it. It should be noted that the toilet of the present invention is not limited to the preferred embodiment shown in Figure 1, but the toilet can also be of a model standing on the floor and comprising a conventional cistern mounted on the toilet. Figure 2 is a cross-section of the toilet of
Figure 1. The bowl 7 is preferably made of enamelled or painted steel or, alternatively, of e.g. stainless steel; in this case, the toilet is provided with fasteners 9 for the side plates and back plate 6 of the toilet.
The top 3 is separate from the bowl 7, mounted on the bowl and secured to it by screws, rivets or the like. The rivets or screws can be covered by the seat 2 mounted on the top 3 (cf. Figure 1) . The top 3 can be made of a painted or enamelled steel plate or, alternatively, of a material which is different from that of the bowl, e.g. ABS plastic. Such a combination allows, among other things, the weight of the toilet to be minimized, which makes the toilet particularly suitable for use in ships, where the weight is of great significance. In addition, the use of different materials increases the number of possible colour combinations for the bowl and the top.
The water channel 14 at the upper edge of the bowl is shaped as an upside-down U and defined by the bowl 7 and the top 3. The outer wall 12 of the water channel is formed by the inner wall of the bowl, whereas the inner wall 11 and top portion 13 of the water channel are formed by the top 3. The inlet 5 for the flushing water leads to the water channel 14, whereby the supplied flushing water is distributed in a conven¬ tional manner by the water channel 14 along the entire upper edge of the bowl 7 to allow the entire inner surface of the bowl 7 to be flushed when the flushing water flows down from the water channel towards the drain.
Figure 3 is a cross-section of the water channel 14 in the toilet. It appears from Figure 3 that the top 3 is mounted on the bowl 7. A gasket 15 of rubber, plastic or similar material is provided between the top 3 and the bowl 7 along the entire contact area between them. The upper edge of the bowl is curved, whereby the top 3 is attached to the edge of the bowl by fixing screws 16. The water channel 14 is thus defined by both the bowl 7 and the top 3, whereby the inner walls of the bowl 7 form the outer wall 12 of the channel 14. The inner wall 11 and top portion 13 of the channel are formed by the top 3, which partly extends into the bowl 7.
The walls of the water channel 14 are preferably enamelled or coated with teflon, for example. This results, for instance, in smaller variations in the flushing characteristics of toilets manufactured in different ways, since the smoothness of the water channels thus varies less among the different toilets.
In Figure 3, a heating coil 17 is mounted round the entire periphery of the bowl, close to the upper edge of the bowl 7. The heating coil is preferably a thermal resistor which constantly heats the top 3 and the seat 2 of the toilet to a temperature of about 30° to 35°C. The heating coil thus heats the top and the seat to a pleasant temperature at the same time that it renders automatic cleaning of the toilet possible. The automatic cleaning can be arranged, for example, by providing the ceiling or back wall of the toilet room with nozzles which sprinkle a cleaning agent on the top 3 and seat 2 of the toilet, when necessary, e.g. after each time the toilet has been used. On account of the heating coil 17, the cleaning agent evaporates quickly from the top 3 and the seat 2, and after a very short drying period, the toilet is clean and ready for use.
Figure 4 is a cross-section of the water channel in a toilet according to another embodiment. The embodiment shown in Figure 4 is identical with the one shown in Figure 3 except that in this embodiment the top is secured to the bowl by screws 16 that do not penetrate the top. Instead, the screw 16 shown in Figure 4 is fastened to the top 3 by spot welding 18. This allows the seat of the toilet to be more freely designed, since in this embodiment the seat does not have to cover the screw heads as in the embodiment of Figure 3.
It should be noted that the above description and the figures are intended merely to illustrate a preferred embodiment of the invention. The embodiments of the present invention are thus limited only by the appended claims.
