Description

The invention relates to a drain for a drain tank in accordance with the general definition of the claims according to paragraph 1.

The standard toilet has a profiled U-shaped flushing ring open at the bottom, which bends around it, and in which lime scale may form. Toilet bowls without upper U-shaped flushing rings are also known. However, during flushing in a toilet bowl without a ring, water sprays can spill over the edge of the toilet bowl. Such splashes of water can be prevented by reducing the flow rate of water to flush the toilet.

From DE 3008524 C2 it is known that there is a standard drain for a drain tank, with which you can control the volumetric flow of water for flushing, that is, the volume of water flowing from the flush tank per unit time. There is a housing in the drainage system, in which an adjustable pipe is located in the axial plane. The pipe is vertical to the toilet and has a disc valve, which is part of the drain valve. By lifting the pipe, the drain valve opens. Thus, the water in the flush tank flows out of it through the drain channel through at least one drainage window created in the drainage system, as well as through the open neck of the valve.

In the above DE 3008524 C2, for adjusting the amount of water for flushing, a container with a float, which is part of the drainage system, continues in the lower part with an annular partition located at the inner wall of the casing with windows for draining the water. The annular partition has four holes for the passage of water located at the respective drain windows. By turning the container with the float, it is possible to set its annular partition, i.e. openings for passing water to different positions relative to the windows for draining the water, in order to adjust the desired volumetric flow of water for flushing. The tuning mechanism, known from DE 3008524 C2, has a complex structure and can only be realized by fitting a tank with a float installed in the body of the drain device.

The objective of the invention is to create a drain for the drain tank, in which setting the amount of water for flushing will be technically simpler.

This problem is solved by the elements of the claims according to paragraph 1. Preferred advanced training of the invention are described in additional claims.

The invention is based on the fact that in the construction described above, it is possible to vary the diameter of the water passage openings that are in the housing by complexly turning the annular wall to adjust the speed of the flushing water flowing out of the drain tank. If this restriction is waived, the drainage system is equipped with rotary elements in accordance with the characterizing part of the claims according to paragraph 1. Through the movement of the rotary element, the path of water leakage through the holes for water passage that are in the housing can be adjusted, that is, shorten or lengthen it to increase or reduce leak rate. For this, the rotary element is located separately from the window for draining the water, forming an annular gap at a radial distance.

In the technical implementation, the rotary element is preferably located radially outside the housing. In this case, the rotary element is placed in the direction of the wash water flow, above the window for draining water in the housing. Unlike the design described above, the swivel element can be installed as an additional component without changing the internal structure of the drain (in DE 3008524 C2, above, this is called a tank with a float). Thus, by means of the invention, it is possible to carry out a simple manual adjustment from above, rather than dismantling the drainage system.

To ensure perfect regulation, it is recommended that the rotary element be located in the radial direction with respect to the window for draining water in the housing. It is desirable that the rotary element is no longer involved through rotation, but through linear movement, which is easier to implement.

To do this, it is desirable to mount the rotary element on the drainage housing through the unit for adjusting the stroke length and manually adjust it using the assembly for adjusting the stroke length. The stroke length adjusting unit can, for example, be positioned so that it is easy to control predetermined stroke positions — for example, the lower, middle and upper stroke position; or carry out smooth regulation using a lead screw, setting a different length of water leakage for flushing.

In contrast to the structure mentioned above, the pivoting element can be moved outside the structure with a water drain window located in the housing, i.e. at a radial distance from the water drain window located in the housing, and preferably with the formation of an annular gap, as described above located in the direction of the outflow of water from the window. In addition, a turbulent flow can be additionally created in the annular gap, which will increase the leakage path of the washing water.

In the simplest embodiment, the pivoting element can form a pivoting wall that partially or completely closes the enclosure around it. The pivoting wall may have a pivoting edge from the bottom (when viewed in the vertical direction) to direct the outflow of water from the window to drain the water. Alternatively or additionally, the pivoting wall may have at least one passage opening, the outlet valve of which directs the flow of water downward at a certain angle. The outlet valve closes the bypass hole at a predetermined distance, forming a passageway.

Thus, with the drain drain valve open, the water stream can be divided, namely, into the first stream flowing from the passage hole in the annular wall and into the second stream flowing along the edge of the rotary wall. It is desirable that both parts of the flow are again connected in the annular gap between the rotary element and the window for draining the water located in the housing. After that, flushing water flows from the window to drain the water in the housing in the direction of the toilet.

In the embodiment described above, the partition may have passage openings through which flushing water flows in the direction of the drain windows located in the housing. As an alternative, in another design, you can make a partition that is able to close completely, that is, completely close the body with at least one window to drain the water.

For example, a hollow cylindrical casing of a drainage system can, at the bottom, at an annular protrusion (or supporting flange), pass into a lower fitting with a smaller diameter, the flow from which follows to the toilet. It is better that the support flange (i.e., an annular protrusion) is located above the pivot wall in the radial direction and at the radial distance. In this case, the support flange of the housing can simultaneously function as a lower axial stop on the side of the housing. The pivoting partition in its lower position may be limited by its lower edge and the support flange from the side of the housing. The stroke length of the rotary partition in this case is limited by the axial stop on the side of the housing and the upper axial stop, which defines the upper open position of the partition. In the closed position, the pivoting wall can completely close at least one window for draining water in the housing, but at the same time be at a small distance from the inner radial side of the housing, which is determined by the annular gap between them.

As mentioned above, the rotary element can be manually adjusted using the stroke length adjustment unit. In a specific embodiment, the unit for adjusting the stroke length may have a drive spindle, which is driven by the user and connected to a rotary element, including a threaded insert. The drive connection is designed so that the rotation of the drive spindle initiates a change in the stroke length of the rotary element. In a preferred embodiment, the drainage housing has a bracket in which the drive spindle is mounted so that it can rotate but is locked in the axial direction. In addition, the drive spindle may also have an external threaded gear, is located in the threaded insert together with the internal thread, which is equipped with a rotary element with an adjustable stroke length.

The best options for the development or improvement of the invention described above and / or in additional paragraphs, can be used separately or in any combination with each other, for example, in the case of clear dependencies or incompatible alternatives.

The invention and preferred options for its development or improvement will be explained in more detail using the drawings.

FIG. 8 and 9 are a standard view showing the pivoting element in various travel positions.

In FIG. 1, a drainage system with a hollow cylindrical body 1 is shown separately, which at the bottom, at the annular protrusion 2, passes into a lower fitting with a smaller diameter, from which water flows to the toilet through a path not shown in this drawing. Case 1 in FIG. 2 is supported by its annular protrusion 2 with an intermediate connection with the seal 5 on the edge of the outlet 7 (Fig. 2) on the bottom 9 of the flushing tank 11. In the vertical direction of the equipment z, upstream openings 13 are connected to the annular protrusion 2 from the housing side 13, which are circumferentially separated from each other by uniformly distributed partitions 15 (Fig. 1). Radially inside and coaxial to the axis of the housing is a valve disc 19, which is located at the lower end of the pipe 17 shown in Fig. 1 and 2, and together with the pipe 17 is adjusted in the axial direction. The pipe 17 is part of the upper node of the drain valve 18 (Fig. 6, 8 and 9). According to FIG. 1, the valve disk 19 together with the valve seat 21, which is located on the annular protrusion 2, is part of the drain valve 23. The valve disk 19 is connected by a path not shown in more detail in this figure, for example, with a control handle that is manually operated, and with which you can pull the valve disc 19 down to open the drain valve 23.

Radially outside the housing 1 is a hollow cylindrical rotary element 33, made in a separate socket. By means of the rotary element 33 with the drain valve 23 open, the path of the water flow to the drain window 13 is established, that is, it increases or decreases, which will be described later.

The hollow cylindrical pivot member 33 in FIG. 1 has a lower annular wall 35, as well as an upper annular wall 37 at an axial distance. These walls are interconnected by an axial wall 39. The lower annular wall 35, when the drain valve 23 is open, acts as a pivot wall with which it is possible to extend / shorten the flow path of the water for flushing. For this, the pivot wall 35 is equipped with passage openings 41 (FIGS. 2-5), at the upper edges of which the baffles for flow 43 extend outward at an angle and close the passage openings 41, thereby forming a passage gap at a distance. In addition, when the drain valve 23 is open, the lower edge of the pivot wall 35 acts as a pivot edging 45 around which water flows in the direction of the drain window 13.

As can be seen further from FIG. 3 or 4, the pivoting wall 35 of the pivoting member 33 does not have a drive connection with the outer peripheral wall of the housing 1, but is located much further than its window for draining 13 radially outward, forming an annular gap 47 between the draining window 13 in the housing and the pivoting wall 35 .

In the drawings, the pivoting member 33, which is located separately, can be axially adjusted through a stroke length adjusting unit 49, which is indicated in FIG. 1 only approximately. An assembly for adjusting the stroke length 49 is shown in FIG. 1, by way of example, between the upper annular wall 37 of the pivoting member 33 and the housing 1, and is positioned so that the pivoting member 33 can be installed in predetermined positions to discharge h ₁ , h ₂ and h ₃ . In FIG. 2 and 3, a pivoting member 33 is shown in the middle position of the stroke h ₂ , which sets the average length of the direction of water leakage for flushing II to the drain window 13 located in the housing. In FIG. 5, the rotary element 33 is shown in the upper position of the stroke h ₃ , where a short path of water leakage direction for flushing III is selected to the water drain window 13 located in the housing. In the upper position of the stroke h ₃ (Fig. 5), the lower pivot wall 35 and the drain window 13 currently used are located on the axis so as not to overlap each other, and so that the pivot element 33 in its stroke position h ₃ does not performed no functions. In the lower position of the stroke (Fig. 4) of the rotary element 33, the maximum length of the direction of water leakage for flushing I to the drain window 13 located in the housing, which will be described below, is set.

In FIG. 1 or 2, the drainage system is shown in the position that it occupies when the flush tank 11 is empty. When flush water enters the flush tank 11, it also fills the housing 1. If you lift the valve disc 19 using the control handle, the flush water will flow through the window for a drain 13 located in the housing to the bleed fitting 3.

In the middle position of the stroke h ₂ (Fig. 3), the pivoting wall 35 partially overlaps the drain window 13 in the axial direction z. When the drain valve 23 is opened, water leakage directions for flushing II are created, divided at the level of the rotary wall 35, namely, the first part of the stream II _a flowing through the through holes 41, and the second part of the flow II _b flowing around the rotary edging 45. Both shares the flows are reconnected in the annular gap 47, which is below. An additional turbulent flow arises in the annular gap 47, due to which the direction of water leakage for flush II continues to rise to the drain windows 13 located in the housing.

In the lower position of the stroke h ₁ (Fig. 4), the pivoting wall 35 completely overlaps the drain window 13 in the axial direction z. This leads to the fact that the intensity of the direction of water leakage for flushing I becomes greater compared to FIG. 3. This stream is also divided at the level of the pivot wall 35 into a stream share I _a and a stream share I _b .

In contrast, in the stroke position h ₃ (Fig. 5), the pivoting wall 35 and the drain window 13 located in the housing in the radial direction are adjacent and there are no partitions between them. Thus, the rotary element 33 does not perform any functions and does not affect the flow path III, which is directed to the drain window 13 located in the housing.

In FIG. 6 shows a drainage system according to a second construction example, which generally has the same functions as the construction example shown in figures 1-5. Therefore, elements with a similar design or function are indicated by the same numbers.

So, the housing 1 is located on the radial plane from the outside of the hollow cylindrical rotary element 33. The rotary element 33 in figure 6 is not located along the axial axis (in contrast to Figs. 1 and 2). In addition, the pivoting member 33 has an installation-friendly design, flat in the axial direction, with the pivoting wall 35 and the threaded sleeve 63, which is located on the side of the pivoting wall and whose function will be explained later, are completely closed — in contrast to the previous embodiment.

On the bottom side, the housing 1 is equipped with an annular protrusion / supporting flange 2, which provides installation support in a manner not shown in the figures, with the seal placed on the bottom 9 of the flushing tank 11 (cf. FIG. 2). In contrast to the first embodiment, the supporting flange 2 projects beyond the pivoting wall 35 in the radial direction on the radial protrusion Δy (Fig. 9). Thus, the supporting flange 2 forms a lower axial protrusion from the housing side, defines the closed position h _{zu of the} pivoting wall 35. At the same time, an upper axial stop 53 (figures 8 and 9) is formed on the lower side of the drain valve assembly 18, which defines the upper open position h _auf , shown in FIG. 8. In the upper open position h _auf, drain windows 13 are located in the housing, almost completely open. In contrast, drain windows 13 are located in the housing, in the lower closed position h _zu (not shown) are completely overlapped by the pivoting wall 35. In FIG. 9, the pivoting wall 35 is shown approaching its lower closed position h _zu , but still at a small axial distance a from the supporting flange 2.

Thus, according to figures 6-9, the rotary element 33 is located between the supporting flange 2 in the housing and the lower side of the drain valve assembly 18 and has the ability to control the stroke. The drain valve assembly 18 in figures 6, 8 and 9 is supported by the upper part of the hollow cylindrical body 1 and is connected to the body 1 via a locking connection not shown in the figure, which can be disconnected without a tool. For easy mounting / dismounting of the drain valve assembly 18, it is especially important that the rotary element 33 is located under the safety valve assembly 18 and that the rotary element is designed as a separate part not aligned with the safety valve assembly 18. When dismounting, only raise the drain valve assembly 18 - by disconnecting the locking connection not shown, with the possibility of separation, in the vertical direction of the drainage system z up, and the rotary element 33 located at the bottom should not create obstacles.

As follows from figures 6-9, the node for adjusting the stroke length 49 is implemented with a drive spindle 55, which is started by the user and has predominantly parallel axes with a descent fitting 3, as well as a pipe 17 of the drain valve 23. The drive spindle 55 has a threaded engagement with a rotary element 33, namely, in such a way that when the drive spindle 55 is rotated, the stroke of the rotary element 33 in the axial direction can be adjusted. In addition, the housing 1 has a bracket holder 57 that protrudes laterally outward in the radial direction and has a through hole through which the lower end element 59 of the drive spindle 55 passes. On the lower end element 59 of the drive spindle 55 there is an annular groove, which is not shown in more detail. It includes the outer edge of the through hole of the bracket holder 57 with a small cycle of movement. Thus, the drive spindle 55 can rotate in one direction, but be fixedly fixed on the other side. In addition, an external thread 61 is located on the end member of the drive spindle 59, which has a threaded engagement with the internal thread of the threaded sleeve 63, which has already been mentioned above and together with the pivoting wall 35 is an integral part of the pivoting member 33.

As follows from figures 6-9, the threaded sleeve 63 of the rotary element 33 in the axial direction is located directly under the bracket holder 57 in the housing. In this case, the threaded sleeve 63, when viewed in the radial direction, is positioned on the same horizontal surface as the pivoting wall 35, that is, it is on the same axis as the pivoting wall 35 in the radial direction. Due to this, the already indicated flat design of the rotary element 33, which is favorable for the installation space, is formed.

Figure 9 shows the pivoting wall 35 in proximity to its closed position h _zu . In the closed position h _zu , the indicated direction of water leakage for flushing IV is formed, when flushing water flows from above the annular gap 47 between the inner radial plane of the casing 1 and the outer radial pivoting wall 35, and then continues to flow through the drain window 13 in the casing to the drain fitting 3.
