Device for metered addition of detergent flowing through a water pipe water

The invention relates to a device for metered addition of a flowable substance into a line for a liquid medium under overpressure, especially for adding detergent to a water pipe flowing water.

For example, when cleaning vehicles, especially motor vehicles, also so-called Car wash brushes are used, which are provided with a connection for the supply of tap water. In the Cleaning with the help of such washing brushes has hitherto been the problem, evenly during the washing process and add dosed detergent to the washing water.

The present invention is therefore based on the object, the possibility of a uniform and automatic Supply of detergent for the washing process

used to create tap water. This object is achieved according to the invention with that in the characterizing part of the claim 1 specified invention solved.

Before the start of a washing process, the container of the device according to the invention is filled with a certain amount Detergent, expediently in liquid form, filled with the metering valve closed. After closing of the container, the interior of the container is under a certain pressure, the pressure used for washing Water at least set excessive pressure during the water withdrawal. To create this heightened Pressure in the interior of the container, there are various options, which will be discussed below will.

By opening the dosing valve located at the outlet of the container, the washing water can be added in the desired dosage Detergent can be added. The size of the container or that which remains as a compression space Space of the 3ehälters is expediently the demands on the duration of a washing process or on the amount adapted to the water used in a washing process *

A preferred embodiment of the invention is characterized according to claim 2, characterized in that the container consists essentially of a lower and an upper container part, which container parts are airtight are connectable to each other and of which the lower container part is used to receive the detergent, while the upper part of the container is used to create a cavity of a predetermined minimum size in the container. This embodiment is easy to manufacture and ensures that only a certain amount of detergent in the container,

namely in the lower container part, and that there always remains a cavity, essentially formed by the upper container part, of a predetermined minimum size I , which acts as the compression space of the one in the container

I used closed air. The enclosed in the container,

"Compressed air exerts the necessary pressure on the im

i the detergent in the container so that the detergent is dispensed according to the setting of the dispensing valve can get into the pressurized tap water or wash water.

In the preferred embodiment of the erfindungsge i MAESSEN t means according to claim 2 can for generating the

To control the pressure prevailing in the container, the container can furthermore be provided with a display instrument for the level of pressure in the container.

Finally, according to the proposal according to claim 6, it is also expedient that in the outlet of the container subsequent line piece between the connection for the inflow of the medium and the confluence the outlet of the container is provided with a valve to prevent the inflow of detergent into the Inflow pipe of water;

A particularly advantageous embodiment of the invention is according to claim 7 is that the container with a washing brush or the like. Connected to form a unit. In this context it is also expedient according to claim 8, that the washing brush is provided with a valve that can be operated manually if necessary.

With reference to FIGS. 1 and 2 of the drawing, the invention is explained in more detail below using an exemplary embodiment.

The drawing shows a container 1, which consists essentially of an upper container part 2 and a lower Container part 3 consists. The container parts are via the thread 4 of the container part and the thread 5 of the container part 3 and 3 firmly and airtightly connected to one another by screws. On the side facing away from the thread 5, the runs Container part 3 into an outlet 6 from. In the area of the outlet 6 there is a metering valve 7 with a handle 8.

On the side of the container 1 facing away from the outlet 6, there is a valve in the wall of the container part 2 9 for the supply of compressed air, e.g. B. with the aid of an air pump and a pressure display instrument 10.

On the side of the container part 3 facing away from the thread 5, the outlet 6 ends in an opening 14 to which a line piece 11 connects on both sides. The line piece 11 is connections 12 and 13 for the connection one z. D. flexible water pipe or the like. Furthermore, between the mouth 14 and the connection 12 in the line piece 11 a check valve 15 is provided.

With the help of the connections 12 and 13, the container 1 with the relevant end of a, for example, flexible Line 16 or 17 are connected (see Fig. 2). The line I ^ on the other hand leads to a tap 18, while the line 17 leads to a washing brush 19 with a manually operated valve 20.

The operation of the device shown in FIGS. 1 and 2 is as follows:

The container 1 is used for the purpose of filling washing

medium screwed into the container, after which with the metering valve 7 closed, a certain amount of detergent is placed in the container part 3. Subsequently, the container part 2 is screwed back onto the container part 3, so that the container 1 is hermetically sealed.

Following the filling of the container 1 with detergent and hermetically sealing the container with the metering valve 7 closed at the same time Valve 20 on the washing brush 19 is closed. A valve labeled 21 is then connected to the tapping point IS opened so that pressurized tap water in the lines 16 and 17 and in the line section 11 can reach the container 1.

While the valve 20 on the washing brush 19 is closed, the metering valve 7 is opened. Consequently as much tap water will get into container 1 while compressing the air in container 1, until there is a pressure equalization between the (static) pressure prevailing in the line section 11 and the pressure in the container 1 sets. The metering valve 7 can then be closed again.

As soon as the valve 20 of the washing brush 19 is opened, the pressure prevailing in the line section 11 is exerted known reasons significantly reduce, so that between the pressure in the container 1 and the pressure in the line piece there is a certain pressure difference. By opening the Dosing valve 7 can now with the help of the excess pressure existing in the container 1 compared to the pressure in the Leituncsstück 11 the tap water flowing through the Leituncisstückk 11 the detergent in the container 1

metered and automatically fed until there is again a pressure equalization between container 1 and line piece 11 has set.

The container 1 with various connections and instruments can - connected to the lines 16 and 17 in be set up close to the work area »However, a solution in which this Container with a VJasch brush or the like is already constructive is connected to one unit.
