DE3021999A1 - DEVICE FOR IMPLEMENTING DETERGENTS INTO THE WASH CONTAINER - Google Patents

Abstract

The device has a central cylindrical container (1), into which two inflow connections (2, 3) open in the radial direction. Arranged diametrically relative to these inflow connections are two first outflow orifices (4, 5), and between these is located a third outflow orifice (7). A water jet from one inflow connection (2, 3) or the other passes by way of the free zone within the central container (1) to the opposite outlet orifice (4, 5). If water flows simultaneously through the two inflow connections, most of the jet passes into the third outlet orifice (7). When washing agent is being introduced into an automatic washing machine, this device makes it possible, with only two water valves and without any other movable parts, to introduce the washing agent, the main washing agent and finally a finisher. The free path in the container (1) prevents a return flow. <IMAGE>

DESCRIPTION

Device for introducing detergents into the washing container

The present invention relates to a device for introducing detergents into the washing container according to the generic term of the independent claim.

According to CH-PS 502.248, an arrangement has become known, in which, for example, there are three vessels each for holding a detergent. Above these vessels there are controlled valves with an outlet nozzle for introducing water into the vessels. So can

a pre-wash, main wash and rinse aid selectively fed into the wash tub of a washing machine will. The distance between the nozzle openings and the vessels prevents backflow, so that no detergent can get into the fresh water supply, as is the case with many waterworks for automatic washing devices was prescribed.

The disadvantage of such an arrangement is the reversal of the water inflow with the three valves.

The object of the invention is therefore to reduce this effort and still have three separate detergent containers rinse individually and comply with backflow prevention regulations.

According to the invention, this is according to the features in the characterizing Part of the independent claim solved.

An embodiment of the invention is described below with reference to the drawings.

Show it:

Pig. 1 shows a floor plan of the device according to the invention, partly cut along the section line I - I in Fig. 2,

Fig. 2 is an elevation of the device, in which the inner walls are indicated by dashed lines, and

FIG. 3 shows a sectional view along the section line III - III in FIG. 2.

The device for introducing detergents into the washing container an automatic washing machine consists of a central part with a cylinder wall 1. The bottom surface 8 is conical and has an opening 9 at the cone tip. Two inlet nozzles 2, 3 opening radially into the central part are on first outlet openings arranged diametrically to these 4, 5 aligned. A funnel is provided with a bottom wall 11 and two side walls 12, 13 that are perpendicular to it which leads to a second outlet opening 7. This second outlet opening is provided with a duct 14 7 is connected to a remote dispensing opening 6.

130012/0606

The middle part with the cylinder wall 1 and the line channel 14 are closed at the top with a cover wall 10.

Flows in this device as shown in FIG. B. water through the inlet nozzle 2 in the direction of the filled arrow, so this water leaves the middle part after overcoming the free distance in the middle part through the outlet opening 4, according to the one drawn there, likewise filled Arrow. If, on the other hand, the water flows through the inlet connection 3, according to the white arrow, it leaves the Middle part through the outlet opening 5, according to the white arrow drawn there.

As can now easily be seen, the greater part of the inlet pipe 2 and 3 introduced at the same time leaves Water flows through the cylinder housing 1 through the funnel 11, 12, 13 and flows through the conduit 14 through the Opening 6 from, as shown in the drawing by a half black, half white arrow.

Because the angle ρ, which limits the arc where the side walls 12, 13 of the funnel penetrate the cylinder wall, is greater than the angle cL between the axes of the inlet nozzles 2, 3, it is achieved that the more diffuse common jet from the two inlet nozzles mostly

130012/0606

can flow through the channel 14. For example, the angle oC = 48 ° and the angle / 3 = 60 °.

The bottom wall 11 of the funnel is inclined at an angle 45 with respect to the top wall 10. The nozzle openings the inlet port 2, 3 are, for example, each 5 mm and the Outlet openings 4, 5 are designed to have a diameter of 6 mm.

With this device there are only two controlled inlets needed to switch the water in three different directions. If with simultaneous introduction of water If water still flows through the two inlet ports 2, 3 through the two outlet openings 4, 5, this can only be advantageous be. By having three containers arranged next to one another first, for example via the inlet connection 2, water to the Container with the pre-wash agent (not shown) through the outlet opening 4, then water via the inlet connection 3 to the container with the main detergent (not shown) through the outlet opening 5 and finally via both inlet ports 2, 3 flows to the middle container for the fabric finisher (not shown) are in this last phase all three containers rinsed out.

The free path in the middle part creates a backflow preventer formed by possible backflowing washing

medium through the outlet openings 4, 5 to the bottom S and through the opening 9 drains and can under no circumstances get into the inlet connection.
