EP2226437B1 - Method and cistern for supplying an additive in such a cistern - Google Patents

Description

The invention relates to a cistern according to the preamble of claim 1.

Cisterns of the type mentioned have long been known. They allow a rinsing release on the actuator plate, for example by pressing or pivoting a button. In the prior art cisterns have become known, which allow means for filling an additive in the container of the cistern. This additive is solid or liquid and designed as a disinfectant and / or fragrance. The additive is added to the cistern and thus to the rinse water. It can be designed as a solid substance, for example as a cube, which gradually dissolves in the rinse water. If it is completely dissolved, it must be replaced. For this purpose, there are already numerous proposals in the prior art.

In the DE 20014 275 U discloses a flushing container for wall mounting, which has an opening in a front panel for the insertion of disinfectants in the washing compartment. This should allow easy and rapid insertion of the disinfectant. On the front panel a removable operating mechanism is attached. In order for the opening to insert the disinfectant is accessible, the actuating mechanism must be removed from the front panel in advance. Removing and re-installing such an actuator is not possible for the common user without detailed instruction.

The DE 10246866 A discloses a cistern which has a filler opening in the lid for filling an additive. A flap is used to open and Close the filling opening. In a concealed cistern, such a filling opening is hardly possible.

The DE 200301329 U discloses a flushing cistern having in a pusher means a filling opening, which can be covered by a flap or a slide. How this could be done is not disclosed. Such a filling opening is unfavorable for aesthetic reasons.

The EP-A-0 779 397 discloses a cover assembly having a mounting frame to which an actuator plate is attached. With a special tool, the actuator plate can be removed from the mounting frame. For filling an additive, this cover assembly is not suitable.

The invention has for its object to provide an alternative cistern, which also allows the insertion of an additive.

The object is achieved in a generic cistern by the features of claim 1. In the cistern according to the invention an opening is formed by moving the actuating plate into the filling position, through which the additive can be inserted into the cistern. The actuator plate is firmly connected to the cistern in the filling position. Since the filling opening is created by a movement of the actuating plate, an additional separate filling opening is not required. In the operating state, the filling opening is thus not recognizable.

The filling of a solid additive is particularly simple and safe, if according to the invention in the access opening a chute is arranged, on which the additive can slip into the cistern.

According to the invention it is provided that on the inside of the actuator plate, a throw-in cup for the additive is arranged, in which the additive is laid and with which the additive is transferred to the chute when the actuator plate is moved from the filling position to the operating position. The user therefore only has to place the admixture in the throw-in cup, which is easy and safe to accomplish. When closing the actuator plate, the additive is automatically thrown onto the slide and finally into the cistern.

According to a development of the invention it is provided that the bearing device comprises a pivot bearing, so that the actuating plate is pivotally away from the inspection opening in the filling position. The actuating plate is pivoted here, for example and preferably around a lower edge. The upper edge of the actuator plate is thus moved away from the mounting frame or the inspection opening. It is thus formed at the top behind the actuator plate an opening through which The additive can be easily and safely inserted into the cistern.

According to a development of the invention it is provided that the mounting frame and the holding frame form a replaceable unit. This is preferably designed so that they are compatible with already known conventional actuation plates. The named unit is thus particularly suitable for retrofitting already installed cisterns. In this case, only the already mounted mounting frame must be replaced by said unit.

According to a development of the invention it is provided that the holding frame is pivotally connected to a pivot bearing with the mounting frame. The pivoting movement is preferably limited, so that the actuating plate, for example, by less than 45 ° is pivotable. The pivot bearing is in this case preferably arranged at the lower edge of the mounting plate or the actuating plate. For pivoting, in this case, the actuating plate can be grasped at an upper edge and moved away from the fastening frame. After filling then the actuator plate can be pivoted in turn at the top in the operating position.

According to a development of the invention it is provided that is arranged behind the inspection opening of the collecting container for the additive. This collection container is located If the cistern is full at least partially in the rinse water, so that it gradually dissolves in the rinse water.

According to a development of the invention it is provided that the mounting frame and the bearing device for the actuator plate form a kit for retrofitting an already mounted cistern. The storage device is formed here in particular by the said holding frame. However, this is not mandatory for the invention. Instead of the holding frame could otherwise be provided a part which is fixed to the mounting frame and which allows a movement, for example a pivoting movement of the actuator plate. The kit also preferably includes the said chute and / or the collection container. This collecting container is stored for example and in particular on a known bearing block, which is located behind the inspection opening.

In the method according to the invention, it is provided that the actuating plate is moved from the operating position into the filling position, that the additive is inserted behind the actuating plate and the actuating plate is moved to the operating position. The said movement is in particular a pivotal movement about a lower edge of the actuating plate or the mounting frame. The additive is in particular a solid substance, for example a cube. In principle, however, a liquid additive is also conceivable.

Further advantageous features emerge from the dependent claims, the following description and the drawings.

Fig. 4

a section through a portion of the inventive cistern with removed actuator plate.

The cistern 1 has a container 2, for example made of plastic, which has an interior 4, in which a not shown here outlet valve is arranged. In the interior 4 there is also an inlet valve with which rinsing water can be introduced after flushing. The cistern is in particular a concealed cistern and has an inspection opening to which a Bauschutzrahmen 7 is fixed, which engages in an opening 9 of a wall 8. This Bauschutzrahmen 7 is deep according to the thickness of the wall. The Bauschutzrahmen 7 is not mandatory for the invention. On the Bauschutzrahmen 7 or optionally directly on the container 2, a mounting frame 10 is fixed, which with a support frame 12 according to FIG. 3 a storage device 11 forms. The mounting frame 10 serves to receive actuating means, not shown here, which are connected to the outlet valve and which make it possible to open this actuator when actuated.

The holding frame 12 serves to mount an actuating plate 30, which has at least one button 31 for flushing release, which is pivotable on a front side 38 against a spring element 34. Instead of a key 31 but here also other release means, such as a pusher or the like are conceivable. In principle, a non-contact rinsing release is also conceivable. For a revision, the actuator plate 30 can be completely removed. For releasable attachment of the actuator plate 30 to the bearing device 11, the actuator plate 30 has a lower edge 32 which is suspended in a known manner to a spring element 14. Further, the actuator plate 30 has an upper edge 33 which engages in the mounted position in a groove 35 of the holding frame 12. This groove 35 is located immediately in front of a front side 36 of the wall 8 '. To mount the actuator plate 30 is suspended at the lower edge 32 on the spring element 14 and then moved against the retroactive force of the spring upwards, so that the upper edge 33 can engage in the groove 35. By the power of Spring element 14, the upper edge 33 is held in the groove 35. To release the actuator plate 30, this is pushed against the force of the spring 14 upwards, so that the upper edge 33 is lifted out of the groove 35.

The holding frame 12 is pivotally connected to the mounting frame 10 at a hinge 13. The holding frame 12 has an operating position, which in FIG. 4 is shown. In this operating position, the actuator plate 30 is according to FIG. 1 created on the front side 36. The other position is a filling position, which in FIG. 2 is shown. In this, the holding frame 12 is according FIG. 3 pivoted. The actuator plate 30 is further fixedly connected to the mounting frame 10, the upper edge 33 is here, however, at a distance from the mounting frame 10 and zur Frontseite 36 angeordnet. Arranged. Between the upper edge 33 and the front side 36 thus an opening 42 is formed here. The pivot angle of the holding frame 12 is limited by two webs 44, which in the filling position according to FIG. 3 each abut a cam 45 of the mounting frame 10. To form the opening 42, the actuating plate could in principle also be pivoted about another edge, for example on one side edge or, in principle, the actuating plate 30 could also be mounted so that it is displaceable to release an opening.

In the operating position of the holding frame 12 is latched to at least one locking means 20, for example a detent spring. This locking connection can be solved by the actuator plate 30 is taken at the upper edge 33 and pulled away from the front side 36. If the actuating plate 30 is pivoted from the filling position into the operating position according to arrow 40, then the spring 20 automatically engages on the holding frame 12. Instead of a latching connection is also another releasable connection, such as a magnetic connection or the like conceivable.

On the holding frame 12, a feed cup 17 is attached to the back, which in the filling position according to FIG. 3 protrudes into an opening 41 of the mounting frame 10. If the holding frame 12 from the in FIG. 3 shown filling position moves into the operating position, the throw-in cup 17 is further moved through the opening 41 against the container 2. As a result, an inserted into the insertion cup 17 additive 43 is moved through the opening 41 and pushed onto a chute 16 become. In the mentioned movement of the holding frame 12 of the Einwurtbecher 17 is moved downward, so that said additive 43, which is for example designed as a cube, falls on the chute 16 and on this further down finally enters the interior 4. The chute 16 is pivotally mounted on a hinge 18 on the mounting frame 10. This allows adaptation to different depth Bauschutzrahmen 7. In addition, the chute 16 can be cut to length, if necessary.

In the container 2, a collecting container 15 is arranged on a holder 46. The holder 46 is attached to a bearing block 5 at an upper end. The collecting container 15 is arranged so that an additive 43 sliding downwards on the chute 16 drops into it. The collecting container 15 is open on the underside and is at a height in which it is usually located in the rinse water. From the additive 43, the intended substance is then released. The substance is for example a disinfectant and / or fragrance. Such additives or cubes are commercially available.

The actuator plate 30 may be formed as already known. The actuator plate 30 may be, for example, a known plate of the applicant. The bearing device 11 is designed so that it can be mounted instead of a known mounting frame or an already mounted mounting frame can be replaced by the bearing device 11. This thus allows easy retrofitting known mounted cisterns. The kit, which allows retrofitting, thus comprises at least the bearing device 11. In addition, this kit also includes the throw-in cup 17, the chute 16, the holder 46 and the collecting cup 15. The holder 46 is formed so that it on a known bearing block. 5 can be hung.

For retrofitting, the mounted mounting frame is removed. Subsequently, the holder 46 is inserted with the collecting container 15 in the container 2. Subsequently, the storage device 11 is attached to the Bauschutzrahmen 7. The chute 16 can be preassembled in this case. This also applies to the throw-in cup 17. Now, the actuator plate 30 according to FIG. 4 placed in the direction of arrow 39 on the bearing device 11. The back 37 of the actuator plate 30 is now on the support frame 12. As already explained above, the upper edge 33 engages in the groove 35, wherein the spring element 14 is tensioned. The cistern 1 is now ready again and allows that filling with an admixture 43. The rinsing release takes place as before the retrofitting.
