Cleaning agents such as washing agents use up cleaning agents Usually in large, cylindrical transport containers bought, dio in general a content before. own about 110 l. The cleaning agent is used especially in the United States of! Jordanians! κα in general in such transport containers.

In a company like EeDtaurrmt, the cleaning agent is used Used in automatic dishwasher. Jp & e GeBChirrspuliaaachine has a detergent tank that has a Remove a large amount of detergent solution. The Gesohirrspüi machine uses this ash medium oil during a

There are lists of periods of time, for example a sago, and again, until the used solution is replaced by a fresh solution. At nornaler. Use rirö, however, a tsil der ^ ü.F.chv? A-hlelVJ '.. v-> r nit Lecenamittelrcaten and iett removed from the GoGchlrrspül ^ cchino, un to keep the rest of the detergent lucu: .. £ εο saucer as much as possible. In order to make up for these losses, v7as3er is added to the Y / aachraitteltank so that the filling menu always remains the same. This of course reduces the concentration of the concentrate in the medium tank.

To keep the concentration of detergent in the average tank always at the desired level, detergent has to be refilled from time to time. To simply increase the concentration of the switchgear solution, simply fill the detergent tank of the washing machine with powdered detergent from time to time. However, the process is unsatisfactory. On the one hand it requires a tichr or less constant attention of an operator.

Medium concentrate in the ash medium tank with this procedure during a certain period of time over a wide Area,

Attempts have been made to overcome this Hachtell by maxi provided a device which automatically concentrated Detergent solution refills the detergent tank when the concentration of the detergent below a certain Value drops. To achieve this, one has .electrodes in the Arranged detergent tank, which can measure the electrical conductivity of the detergent solution. Besides, one has a storage container for concentrated detergent solutions

In the case of a. Construction uses an open storage container. On this stock L-Ic holder can be placed on one side of an open 110 l- ^ rtinöportbuitierfer-irt, i'.ass the openings of both Leh. ^: filters on top of each other. Between the storage container and the ironaport container, a flat sieve is arranged, the "rcrru". ^ Nd is fine, in order to prevent a practically unhindered passage through the i-as sieve. In the storage tank there are a number of upwardly directed V / aBSer ^ iritsdüser. so arranged at a distance from each other that3

made of thick DUoan ia gusty forces

Water the entire underside of the flat sieve arranged over the nozzle a wet night. This gives a saturated detergent solution which fills or drips through the sieve into the storage container. This concentrated detergent solution can be pumped into the detergent tank when the concentration of the detergent solution in the detergent tank; drops below a predetermined V, 'ert. If. concentrated detergent solution is pumped from the storage tank into the Yfaschraitteltaiik, the level of the detergent solution in the storage tank sinks below the probe, whereby the water supply to the Siritz nozzle is switched on again, so that new concentrated detergent solution reaches the storage tank in the described way »

This device "used" by the Anraelderin has a distributor head with twelve spray nozzles, which eats in connection with the flat sieve. This combination, however, has proven to be economically unsatisfactory because it leads to the formation of channels within the detergent in the transport container, which in turn leads to excessively high levels of moistening and thus excessively strong caking or sticking of the dry wa.'johinitteli .. The expression "Kanalbildtmg" rr-cll say that the saw-rich approximately vertically running cannula or cavities form powder-free detergent above the sieve.

A satisfactorily working device would not cause any depression in the dry detergent and would only moisten the detergent to a thickness of about 1.5 cm above the sieve. If duct formation does not occur, a large surface becomes powdery {That washing area is exposed to the water jets and therefore also In times when the washing machine is not used, the moistened V'rtschmittol and V; a> m bake out. The caked or sticky detergent is not easy, however If dry, in the '.transport container located detergent channels' form and the detergent is stuck to the intestine zvr ^ ar ^ .oneebacken or susaramange, it is difficult to remove enough detergent from the transport container to the necessary concentration of those in the storage container In addition, too much powdered raw material remains in the transport container and is lost which is practically emptied, thrown away, ie is lost for consumption.

The channel formation in dry detergents is got a multi-nozzle divider and a flat sieve having device presumably caused by this.

According to the presented embodiment of the invention, this sieve is conical formed and opposite the interior of the transport container convex, d. h, öiesea üie'b protrudes into the interior Transport container into it. The conical cover covers that entire open endo of the transport container and "has a The size of the march is sufficient to allow the powder powder to trickle through dry detergent *.? su prevent.

... It didn't fica. that the erfindun ^ sgeiaiuie device "■ -S substantially bessnr and economic ala all known devices operates. Dia single spray nozzle provides a water jet of sufficient size to meet the entire underside dfβ sieve. Since the filter in the large and kenisch S is ganssn formed * If every drop of water hits the waaeersxraJileo practically vertically on the sieve, the result is a more uniform distribution of the water jet than in the known device with high-flow nozzles and a flat sieve, whereby the water pressure in the device according to the invention can be adjusted in this way , i.e. every rope of the water jet hitting the sieve see also.

the desired force * occurs. Because of this uniform Distribution of the detergent needed to dissolve it on the sieve When the water hits it, there is no channel formation in the dry Detergent on.

Surprisingly, in the device according to the invention with the conical sieve and the single nozzle assigned to it, the dry detergent lying on the sieve is only moistened by the incident water jet to a thickness of about 13 μm. In the known Voi'- Cy direction discussed above with a twelve DUeer. Having a distributor head, however, the dry ash medium in the transport container is moistened to a thickness of 10 to 13 cm. When the dry detergent was so strongly moistened, the solidification of the detergent often occurred, which was so great that the impression arose as to whether the transport container containing the dry detergent was empty, although this was actually not the case. The impression that the transport container is empty was created because the water sprayed up could not dissolve enough detergent within the time available for this purpose by the device.

In the present device, in the case of the dry detergent or other cleaning agents in the transport container only moistened by the water jet to a thickness of about 13 mm there is no channel formation at all and thus kelae Solidification or no sticking of the detergent in the transport container on. Even if the transport container is already partially emptied, for example over a weekend is not used and the detergent in the iha can settle, the near the sieve dries Lying detergent is sufficient to ensure normal operation of the device when the same τ / ieder in Is put into operation, d.

No sticking or other solidification of the transport container located Y / ash means instead. Hence can practically daa goeamte '· aschmlttel in the transport container from the water jet into an aqueous solution? convicted been. In practical operation of the device according to the invention It turned out that Gai3 daa in the transport container was subtle Detergent practically completely except for a small amount of heat is automatically removed from the storage container.

Another reason for a DAT K & nalMldung and an Ver sticking does not occur or sonatiges solidifying the Wanchraittels located in the transport container, the £ is emäß the invention v-3rv.-er.de te rvorin.je water pressure. Originally it was assumed that the dissolution of the powder in the transport container is ao worse, the higher the water pressure is chosen. It was invented, however, that $ _a ß hears »? / Acoer print only the channel picture; cause, at the same time increase the dissolution of the powder in the V / & 306r au.

Further features of the invention are also useful for improvement the effectiveness of the device. For example a float should be provided, the amount of eggs concentrated fiber solution in the storage container is at a certain level.

Also, through the present invention, a. Another disadvantage of known devices such as dispensing detergent solutions or the like has been overcome. In these known devices, the detergent often falls out of solution and tends to clog the storage container, which is designed, for example, as a sump-shaped or funnel-shaped container. In accordance with the present invention, two features are proposed to overcome this problem. First, a second nozzle is provided, which practically puts a jet of water under the float while the first is in operation

WasoerdUse conducts to prevent any detergent that may have been filled up from seizing the float. In addition, the second "water jet" serves to dilute the locution, which reduces the risk of detergent or other substances falling out. The second part of the invention is latent in the fact that a continuously working pump is used / ended, the uninterrupted removal of the solution from the storage container and called back into the storage container via a suitable EeipaS line, whereby a constant flow of the solution is generated through the storage container * This critical StroE through the storage container also contributes to the fact that the tightness of the detergent or the like that precipitates out of the solution can be kept as small as it is sufficient.

Leg in S ¹ Ig. 1 to 3 illustrated example of the embodiment of the invention, the sieve 14 is essentially kenisch or conical, the outer edge of the Siabec being welded into the retaining ring 12. On the concave IrLucnseite of the sieve 14 Bind Eöbrere aue ötdhl br standing support rods 15 are attached, which ensure that the sieve 14 brought the desired conical permeability even under load. Since the sieve 14 is essentially conical or conical in shape, the support rods 15 are arranged somewhat like the surface lines or side lines of a cone, their inner ends being welded together at the apex of the cone and their outer ends being welded to the inner edge of the fialteringee 12.

a reservoir for concentrated detergent solution. It has a horizontally outward one. Fleece 10a, which rests on a horizontal part of the frame 17 and thus holds the Sanmel container 18 on the frame 17. The outer edge of the flange 10a is bent up and thus forms a circumferential upright hand 18b. This edge 18b is intended to prevent excess wax from escaping from the Saiamel container 18 and dripping down.

As shown in FIG. 2, the flange 18a is largely designed in the form of a circular ring, but has an extension at one point. The start of this expansion is described below.

Circulation of the concentrated detergent solution prevents » that Bich deposited detergent in the collecting container 18 can. Since the distributor pipe 18 is bent and the openings 49 are located on the outwardly bent side of the distributor pipe a 48 are located, the liquid emerging from these openings 49 sweeps over practically the entire area Bottom of the Can ^ elbehMltera 18.

Said the continuously working pump is a centrifugal pump, the closing of the solenoid valve does not damage the dioirape. When the solenoid valve 45 is open and Wasohaittellc - us is pumped into the tank 4 4, the liquid level in the collecting container 18 drops -Bchalter has been closed, daa Ii agnet valve 34 is opened, βο that pressurized water to the spray nozzles 32 and 42 can flow. As stated above, the water exiting through the spray nozzle 42 is intended to keep the area around the ball 38 clean and also to dilute the solution located in the collecting container 18. The oil emerging from the spray nozzle 32 is sprayed in the direction of the concave underside of the screen 14, Fie schematically in Pig. 3 indicated iet. This water sprayed against the underside of the sieve 14 passes through the sieve and Oefeuohtet read powdered detergents lying on the sieve. The Yfesserdruck is set so that only a small amount of detergent is moistened or made wet above the sieve 14. This moistened or wet detergent goes into a solution with the water and taps down through the sieve 14, where it collects in the collecting container 18. When the ball 38 has again reached the predetermined height, the mercury switch 41 is opened and the solenoid valve 34 closed again, whereby the further supply of water to the spray nozzles 32 and 42 is interrupted.
