Description

Discharge structure of a cistern.

The invention relates to a structure of discharge of a cistern according to the characteristics indicated in the preamble of claim 1.

From FR 2 678 300 A it is known such a discharge structure with a discharge tube that it can be raised in the vertical direction, at whose lower end a sealing element of a valve of download. The discharge structure contains a housing of the structure and a float vessel with a float, as well as at least one drag rod to release, at choice, a larger water discharge or lower water discharge amount by lifting the discharge tube. The float bowl It contains a first opening through which water can flow into the release a water discharge and, in addition, a second opening that it can be closed by means of a closing element, although it is open by releasing the lower water discharge.

In addition, from EP 723 050 A, know a download structure that is designed for a larger water discharge and lower water discharge quantity and contains a discharge valve and a bottom valve with a valve tube or discharge tube. In two containers of  float arranged separately one above the other is arranged in Each case a float. By releasing the lower water discharge quantity, the bottom float remains locked by means of a pin and discharge tube is only held by the float superior, which floats in the water contained in the cistern. For release the water discharge of greater quantity is also released the lower float, such that the discharge tube, in whose lower end the valve or its gasket is arranged discharge tightness, is supported by the two floats.

Starting from this, the invention is based on the task of perfecting the download structure of the mentioned type tending to reduce construction spending and, despite this can be done by discharging water of greater quantity or a Less water discharge with safe operation. The manufacturing cost and the number of components must be reduced. The assembly of the discharge structure in a cistern and, in case necessary, the necessary cleaning or service work must be able to perform in a simple way.

The solution of this task takes place according to the characteristics of claim 1.

The discharge structure according to the invention is characterized by a simple structure with few components. Alone a single float vessel with a float is provided in the upper area of the tank or the structure housing. By releasing the discharge of more water, the tube discharge is sustained by means of the single float and, specifically, until the water has come out of a first opening that does not it can be closed from the float container arranged above. The drag rod to release the major water discharge quantity is coupled with the discharge tube and also contains, conveniently, a separation support by means of which the discharge tube is held in the sole float. The size of the first opening controls the amount of water discharge outlet of greater quantity, taking into account the separation from the bottom of the tank. The float housing contains a second opening that is closed during the discharge of more water and opens to release the lower amount of water discharge. Therefore, during the discharge of less water the water flows more fast of the float vessel, such that the float descends faster and, as a consequence, the bottom valve the cistern closes before in the case of water discharge from greater amount, so that it finally unloads less Water. The mentioned openings are configured so suitable as independent openings, although within the scope of the invention the two openings can also be combined to give place to a single common opening with two partial zones. The first partial zone corresponds to the first opening commented for the water discharge of greater quantity, while the second zone partial of the second opening serves to discharge water from smaller amount together with the associated closing element. Preferably, the output cross section of the first opening or the first partial zone is smaller than the section transverse exit of the second opening or the second zone partial. Especially, the cross section of the second exit opening or the second partial zone - opening is larger than the output cross section of the first opening or the first partial zone - opening a predetermined amount, especially an amount greater than 2 times, preferably more than 4 times. Since only one float and one container are provided float, the expense of manufacturing compared to the structures above known of two quantities of discharge.

In the dependent claims and in the following description are indicated improvements and special configurations of the invention.

The following explains in detail the invention based on the embodiments shown in the He drew. They show:

Figure 1, a longitudinal section of the discharge structure in the resting position,

Figure 2, the discharge structure after release the largest amount of water discharge,

Figure 3, the discharge structure after release the lower amount of water discharge,

Figure 4, another embodiment.

Figure 1 shows the discharge structure in the resting position in which a sealing element 2 is placed above the valve seat of a valve bottom discharge or valve, not shown here in detail, of a cistern. The sealing element 2 is arranged, of known way, at the lower end of a discharge tube 4 that it adopts its lowest position in the rest position. Tube 4 of discharge can move vertically inside a housing 6 of the structure, in the vertical direction or in the direction of the axis 8 longitudinal. The housing 6 of the structure is fixed so defined in the cistern and, specifically, preferably fixedly connected to the aforementioned discharge valve and thereby It presents an alignment that does not vary in relation to the cistern. The discharge tube 4 rises in the vertical direction when activated a downloading process and separates upward from the bottom 10 of the cistern, indicated here schematically, and descends again down to the resting position shown after finishing the download process. The housing 6 of the structure has a predetermined and invariable separation from the bottom 10, while the discharge tube 4 rises upward with the sealing element 2 when releasing a water discharge and, when Finish the download process, again adopt the position of lower rest shown.

The housing 6 of the structure contains a stop tab 12 at the bottom end that is set especially in a domed way and within which you can move the shutter element 2 when releasing a discharge of Water. The housing 6 of the structure includes a lower part 14 and an upper part 16 that is attached thereto, which it is fundamentally configured in a tubular way and in which the discharge tube 4 is driven and / or arranged mobile in the direction of the longitudinal axis 8. Conveniently, between the discharge tube 4 and the inner surface of the housing 6 tubular of the structure or its lower part 14 and its part 16 upper is an annular interstitium. It is essential that in the area of the lower part 14 is not arranged any container of the float or any float, but only one only vessel 18 of the float in the upper area of the housing 6 of the structure or that is associated in the upper part 16. From conveniently, the vessel 18 of the float is formed in the upper part 16 and / or forms a piece with the upper part and / or is configured in conjunction with the housing 6 of the structure.

In the vessel 18 of the float is provided a float 20 which, when activating a discharge process, floats so known up in the water of the cistern. The housing of float, and also the float 20 arranged there in a mobile way, They are arranged at the top of the tank or in the area upper discharge tube 4. Through a support 22 of separation that is placed on the upper edge of the float 20 This is held down in the rest position. Support 22 Separation is coupled with discharge tube 4.

Figure 2 shows the discharge structure of two quantities according to the invention after releasing a water discharge of greater quantity. To do this, by pressing a release button not shown here in detail, dragged up a first drag rod 24. The first drag rod 24 for the discharge of more water is coupled with the tube  4 discharge, which rises with it also to the position shown, such that the sealing element 2 opens the bottom valve and discharge water can effluent. With the first drag rod 24 is further attached the support 22 of separation and, conveniently, is forming a piece, the lower end of which is placed on the surface of the single float 20. Conveniently, the container 18 of the float contains an opening 28 at its bottom 26, through the which can effluent the water that is in the container 18 of the float, while at the same time the discharge water flows to through the discharge valve. The amount of download can controlled by means of aperture 28 sized corresponding, such that the idle running of the housing of the float lasts more than the discharge of discharge water to through the discharge valve. As for container 18 of the float is almost empty, the sealing element 2 reaches the valve seat and the bottom valve is closed again or The download structure.

Figure 3 shows the download structure after releasing a smaller amount of water discharge, so which crawls up to the position shown the second drag rod 30, for example, by pressing a push button release. The second drag rod 30 has a mechanism 32 of drag for a projection 34 of the first rod 24 of drag When lifting the second rod 30, drag the projection 34 is placed above the dragging mechanism 32 and, a as a consequence, the support 22 of the separation and discharge tube 4. The area above the ledge 34 is free or there the drag rod 30 contains a groove 36 for the discharge of lesser water, in which you can move the projection 34 upwards freely when lifting the first drag rod 24 for the largest water discharge amount, without raising the second rod 30 of drag

With the second drag rod 30 it is coupled, according to the invention, a closure element 38 of a second opening 40 of the float vessel 18. Element 38 closing is conveniently configured as a gate slide that also rises when lifting the second rod of drag and release the second opening 40. Conveniently, the second drag rod 30, the drag mechanism 32 and the closure element 38 are configured as one piece component. To get the fastest water out possible for the discharge of water of smaller quantity, the section transverse outlet of the second opening 40 is greater than the output cross section of the first opening 28 an amount  default An amount greater than 2 times, preferably more than 4 times.

The closing element or the sliding gate 38 are preferably arranged in a chamber 42 that is separated of the inner space of the vessel 18 of the float, on its face internal, by an internal wall 44 of the chamber. This wall 44 of the chamber contains at its lower end the second opening 40. In this special configuration, the camera 42 contains in the background another opening through which, while the second is released opening 40, water can effluent out of the container 18 of the float. This additional opening 41 is always completely open

In addition, a strip is provided in chamber 42 46 guide for the drag rod or gate 38 slide. The guide strip 46 and also the wall 44 of the chamber are arranged essentially parallel to the axis longitudinal, which ensures good driving vertical. The wall 44 of the chamber and the guide strip 46 also they are configured in one piece, just like the container 18 of the float, and integrated with the housing 6 of the structure. The camera 42 that is arranged radially inside is set open below, such that in case the second opening 40 be open, water can effluently flow down, out  of the float vessel 18. It can be seen that in the case of a smaller water discharge water flows faster out of the vessel 18 of the float which in the case of a discharge of water of greater quantity, since the water can effluent not only through opening 28, but also through the second opening 40. Accordingly, float 20 descends faster down, with the consequence that the sealing element 2 it relies before on the discharge valve and the process of download ends in advance and there is a remaining amount Default in the tank.

Figure 4 shows, similar to the figure 3, another configuration according to which the float vessel 18 at the bottom it has an opening 48 that is divided into two zones 50, 51 partial. The right partial zone 50 according to the drawing is permanently open, while partial zone 51 left as the drawing closes or opens as needed by means of the closure element 38, as indicated by the dashed line 52. The second drag rod 30 is shown in the position after releasing the lower amount of water discharge, in the raised up position, in which the Second partial zone 51 of the common opening. For downloading more water, which is released by raising the first rod 24 drag, water flows exclusively through zone 50 partial always open. Here, the second zone is kept closed 51 partial by means of the angled part 54 of the closure element 38. After lifting the second drag rod 30, it is also released the second partial zone 51, such that water flows considerably faster outside the float vessel 18 that in the case of the discharge of water of greater quantity and, by Therefore, the download process ends in advance. The wall of the chamber contains a recess 56 through which it is formed a union always open with the remaining area inside the float housing 18.
