Definitions

• the invention relates to a toilet water box machine with a side opening having a container for receiving a solid but soluble in water with the formation of an active ingredient concentrate, the toilet cleaner substance, the container accommodating the toilet cleaner substance in a closed lower part, and wherein the side opening of the container is above the maximum area filled by the toilet cleaner substance and is designed both as the outlet of the active substance concentrate when the water tank is drained and as the inlet of the pure water which rises again when the water tank is filled up.
• DE-OS 28 30 955 describes a plastic container to be used in a toilet water tank for a disinfectant and / or cleaning agent.
• This well-known toilet water machine is made of a plastic with a specific weight of more than one and is intended to Ver need its contents on the bottom of the filled water box.
• the plastic container of this water box machine consists of a lower part which holds the water-soluble cleaning substance as well as an adjoining upper part which is open at the upper end.
• the known container has a lateral bore immediately above the maximum fill level of the detergent substance.
• the well-known water tank machine When used, the well-known water tank machine can be thrown into the cistern of a toilet. Due to the low center of gravity, the machine orientates itself with the opening upwards during immersion and slowly runs full of water through the side hole. It sinks to the bottom of the water tank. The water inside the container dissolves the detergent substance so that an active ingredient concentrate forms in the container. This should be dosed into the rest of the water flowing to the toilet when the water drains after the water level in the water tank has dropped to a level below the tank height.
• a circulation through the upper opening and the lateral opening of the container can also form in the idle state, that is to say when the water box is not in use, so that the water in the water box is already there is increasingly enriched with active ingredient before rinsing.
• the consumption of detergent is corresponding considerable even when the water tank is not in use.
• the invention has for its object to provide a water box machine from which the active ingredient concentrate is only released when the water in the water box has essentially already run out.
• the solution according to the invention for the above-mentioned water box machine with a container in its lower part holding the toilet cleaner substance with a lateral outlet opening for the active ingredient concentrate is that the upper part of the container opposite the lower part receiving the toilet cleaner substance is always for free swimming of the entire device has below the water surface of the filled water tank held output of the side opening designed float and that the side opening is secured with a filled water box against leakage of the active ingredient concentrate.
• the automatic water tank always floats when the water tank is full, but the only lateral opening of the container which is provided as an outlet for the active substance concentrate is below the water surface.
• a second container opening required for filling or emptying the container interior, at least for the purpose of venting or venting, is always located above the water surface, so that the water in the water tank cannot circulate through the container.
• At least one buoyancy body for floating with an approximately vertical container is provided on a freely floating water tank automat of the present type as a float.
• an air chamber can also be provided as a float within the container for floating with the container approximately vertical;
• the container should have a vent pipe which dips from the top downward but ends above the level of the lateral opening and should also be closed when in use - apart from the vent and the lateral opening.
• Such a container filled with toilet cleaner substance according to the first or second alternative can be placed in the toilet water tank without connection or suspension.
• the float depth in the first alternative is determined by the selection of the buoyancy body and in the second alternative by the length of the vent pipe protruding into the interior of the container and the resulting size of the air chamber that forms. Because of this depth, the water is filled via the water itself side container opening intended for the active ingredient release.
• Such a water box automat of the first or second alternative thus has two openings, namely the side opening and the upper (venting) opening, but the latter can never be immersed in water, so that water penetrates the container through the side opening but because of the lack of possibility a circulation cannot flow out:
• a further improvement of the design of the first or second alternative is achieved if the lateral opening is introduced into a shoulder provided transversely to the vertical longitudinal axis of the container, so that the normal of the lateral opening runs approximately parallel to the longitudinal axis.
• the surprising effect is achieved that the dissolved in the container Wi rkstoffzentrate in the floating state of the machine is held inside the container or even pressed into it. Because of the specific, relatively heavy active ingredient concentrate, this cannot flow out of the opening which is directed upward according to the further embodiment of the invention.
• an essentially cylindrical shape can be provided for the container of the aforementioned water tank machine. According to another invention, however, an increased stability against the flow of the flowing water and a better Wi rkstoffum Introduce ung achieved when the container has a substantially conical wall with increasing diameter from top to bottom.
• the container is to be closed at its lower end with a cover having a conical wall or frame with a diameter that decreases from top to bottom. The conical downward tapering cover frame reduces the risk of the water box automatism getting caught in the water box linkage.
• a third alternative of the water box machine according to the invention is that as a float at least one buoyancy container tipping when floating in the direction of the lateral opening is provided, that on the outside of the lateral opening a siphon with upward knee or apex and downward outlet or inlet is formed and that the siphon has an air chamber on the side of the apex with an air bubble closing the apex when the container floats and tilts.
• a container filled with toilet cleaner substance is also placed in the toilet water tank without connection or suspension.
• a depth is given by the float.
• the water is filled at the specified depth Inside the container via the siphon outlet. Only this water reservoir in the container in turn dissolves the active ingredient in solid form. Since the siphon is closed according to the invention when the machine floats by tilting the container with the aid of an air bubble, a connection between the interior of the container enriched with active substance and the pure water remaining outside is excluded.
• the container regardless of the degree of filling with residual detergent substance, always sinks so deeply into the water of the water box that the siphon is always completely below the water level.
• the buoyancy body and its dimensions are therefore chosen so that the container takes an inclined position when floating.
• the buoyancy body or bodies are laid out with a view to tilting the container while floating by about 45 °. arranged. In such an inclined position, immersion of the outlet of the siphon and remaining of an opening on the top of the container above the water level can be guaranteed at the same time.
• an air bubble located in an air chamber adjacent to the siphon migrates into the apex of the siphon. In this embodiment it is therefore a siphon with a closure by an air bubble and is not a conventional siphon with a liquid closure.
• the desired oblique position of the shrinking according to the invention can be achieved by one or more buoyancy bodies on or within the container.
• the buoyancy bodies can consist, for example, of cork, styrofoam or the like.
• a defined inclined position is achieved in a simple manner if a relatively small buoyancy body is provided on the container side above the siphon and a relatively large buoyancy body on the opposite container side.
• the geometry and weight distribution should be selected so that the automatic water tank machine rises.
• the air bubble is then pushed out of the siphon knee into an air chamber provided to the side of it and the Wi rkstoff concentrate in the container can flow into the remaining water after the water level has dropped further.
• Raising the container when it is placed on the water tank floor is facilitated and, like an undesired tilting of the floating container in the case of essentially used, relatively heavy Wi rkstoffsubstanz prevented, if the container in its lower part, in particular in the tightly closing lid provided there, a specific Has a weight of more than one.
• this object is also achieved if the height of the container and the distance of the lateral opening from the container bottom are selected so that the active substance concentrate only runs into the last two to three liters of the draining water content.
• the side opening for an active ingredient outflow is evidently closed as long as the water level around the container has not fallen below a certain level.
• the various dimensions of the water box automat according to the invention possibly also the position of the ventilation pipe, can therefore be easily selected so that the active substance concentrate is only introduced in the last two to three liters of the water box content.
• a further embodiment of the invention consists in designing the side opening of the container in terms of its size and / or arrangement for controlled fragrance dispensing. This solution comes into question above all for the alternatives of the water box automat according to the invention, in which no siphon is attached to this opening. If the normal of the side opening then in certain Is designed in an angular range of 0 to 90 ° with respect to the longitudinal axis of the container, a fragrance release between strong and extremely weak dosage can be predetermined.

• the upper container part is closed except for a feedthrough 16 with a ventilation pipe 10.
• a cover 17 is therefore expediently provided at the lower end of the lower part 3.
