Abstract

In the method according to the invention, an indicator element (33) is arranged above the outlet opening, i.e. above the valve (9) of a urinal, said indicator element degrading somewhat through each use and changing its colour after a prescribed number of uses. The colour change is an indicator which alerts the maintenance personnel that it is time to replace the valve (17). At the same time, it is also possible for cleaning and biodegradable substances to be added to the indicator element (33).

Description

METHOD AND VORRRICHTUNG FOR DETERMINING MAINTENANCE INTERVALS

The invention provides a method for determining the time for the replacement of worn and / or sealing liquid and / or fragrance and cleaning substances in dependence of the use eirves sanitary fixture according to claim 1. The invention is further an apparatus for performing the method according to the preamble of patent claim. 4

In sanitary appliances, such as waterless urinals, it is necessary to replace the appropriate time, the barrier fluid and / or wear in Syphonbereich to avoid bad smells. This is done today either at will or as a result of an unpleasant smell, or in a fixed cycle. However, all criteria are useful neither reliable nor as a variety of urinals are arranged next to each other, particularly in the larger size toilets and experience has shown that not all are equally frequently used. Therefore, it is not possible to know with regard to odors which or which is already giving the urinals bad odors. On the other hand, it makes no sense to replace the early essentially intact valve and Syphonteile at little-used Unnalen.

An object of the present invention is to provide a method for determining the time for the replacement of worn and / or sealing liquid and / or fragrance and cleaning substances in dependence of the use of a sanitary fixture as well as the provision of an apparatus for performing the method.

These objects are achieved by a method according to the features of claim 1 and a device according to the features of claim 4. Advantageous embodiments of the invention are circumscribed m the dependent claims.

By physically and / or chemically became visible change of a used sanitary apparatus and during the use by splashes of liquid (urine) wettable indicator member can m Allemstellung existing and each individual can be monitored individually for a plurality of adjacent sanitary apparatus, and there may be the necessary actions there be made where necessary. This means on the one hand with regard to the odor emission detected early, ie before the first signs are smelled, and, secondly, with little time and money only there a replacement be used where it is really necessary. By a suitable chemical and / or physical composition of the indicator member this can also odorous substances are additionally added to replace those which are usually arranged on the walls of sanitary spaces or output by opening a door. In another dry cleaning materials such as bacteria, enzymes, surfactants, etc. can be added to the indicator element, which hold chemical and / or biological means the sanitary apparatus in and tasteless and also allow maintenance and cleaning of the functional elements in the valve and Syphonbereich and the following drain pipes ,

Reference to an embodiment of a urinal, the invention is explained in detail. The sole figure is an axial section through the device. Show it

1 shows a Vertikalschnittt waterless by a

Urinal, Figure 2 shows a longitudinal section through the elements of the

Valve of the waterless urinal, Figure 3 is a perspective longitudinal sectional view of the partially assembled valve, Figure 4 is a vertical perspective longitudinal section through the assembled valve and Figure 5 is a vertical section through the mushroom-like cap over the valve with a centralized or decentralized opening.

The m Unnal Figure 1 shown schematically 1 comprises a basin 3 with a base 22 which is attached directly or indirectly to a wall. 5 At the bottom 22 of the basin 3 in a recess 7, a valve 9 is inserted. adjoins the tubular recess 7 below in the wall 5 on which the urinal 1 is mounted, leading drain pipe 11 (Figure 1).

2 shows the individual parts of a possible embodiment of a valve 9 are shown. With reference numeral 13 denotes an adapter which can be inserted into the recess 7 of any urinal. 1 By suitable unspecified sealant of the adapter 13 inserted tightly in the drain pipe 11. Also, it sealingly abuts against the recess 7, so that no urine laterally of the inlet funnel 15 can move downward. In the tubular interior of the adapter 13, a valve 17 is held screwed or plugged by a bayonet-type closure. In the valve 17 is an odor barrier 19 is used, as is described for example in WO 2004/059198. Of course, can also be a differently shaped odor trap, for example, such as described in WO 1999/57382 used. Alternatively, the odor trap can also be effected by a barrier liquid such as in the method described in CH 690 917 execution.

Above the valve 17 a cap 21 is arranged, which comprises for example a mushroom-like cover 23, are integrally formed on the feet 25 with which the cap 21 can be fastened spaced above the valve 17th Since all the parts are made of plastic, the connection between the cap 21 and valve 17 by an unspecified snap mechanism can take place. Over the cap 21, a key 27 is shown, which can be with the valve 17 in the adapter 13 and for exchanging secured removed (Figures 2 and 3). The key 27 is not part of the device.

In the sectional illustration according to FIG 4, all elements are shown assembled and connected with the key 27 to each other on the adapter. 13 In this figure, the half-space under the hood 23 is shown empty of clarity. The hood 23 and the cap 21 protects the lead-in area 29 of the valve 17 from clogging by, for example, cigarette butts, scraps of paper etc. in the enlarged schematic view of the cap 21 in Figure 5 it is evident that according to the invention the space enclosed by the hood 23 space 31 with a is indicator element 33 filled completely or partially."The indicator element 33, which has been introduced in a pasty, liquid or other form in the cap 21, includes in addition to a shaping matrix enzymes and / or surfactants and / or bacteria and / or cleaning agents and / or dyes, etc. These substances are in each use of the urinal 1 of reasonably splashing urine droplets 37 wetted. the wetting takes place on the one hand from below by urine droplets 37, resulting from the Unrinstrahl incident from outside of the cap 21 on the bottom 22 of the urinal 1 and the other by urine which by one in the cap 21 formed central aperture 35, if one is present, is incident on the floor 22 and is partially reflected. the indicator element 33 is / chemically adjusted physically in such a way that, after a predeterminable number of uses of the urinal, either fully decomposed by dropwise wettings and / or that its color at least in the contact area with the hood 23, welc he has been made of a transparent material changes. This color change, either through reduction and elimination of indicator or color change is visible from the outside without further aids. A maintenance team, which seeks for cleaning and maintenance of the urinal 1, these periodically may also consist of a larger number of juxtaposed urinals 1, as they are, for example, set up on stations in restaurants, airports, etc., readily recognize which of the valves 17 and exchanged / or indicator elements 33 or where barrier fluid must be added. The life span of the indicator element 33 is tuned to a safe service life of the valve 17 or the sealing liquid and ensures that the latter is not defective during this period and thus can occur odors in the sanitary room. Depending on the chemical composition of the indicator member 33 this may, together with the cleaning substances which purely keep the valve 17 from clogging, also contain enzymes and bacteria which enable biodegradation of urine mud in the conduits and prevent the build up of urine stone, both in the valve 17 and in the subsequent sewers 11. Of course, a fragrance may be added to the indicator element 33rd This is then given user-dependent. but a major proportion is in any case a substance that, the duration of which is predetermined in the course of use, color changes.

Alternatively, the indicator member 33 may also consist of a introduced in the sky of the hood boundary layer 32 of an indicator and an underlying ground, which is degradable. The turning color layer 32 is so only in contact with the urine splashes or droplets when the underlying abbaυbare indicator element 33 is actually mined. The indicator element 33 has to go through this no color change.
