A second inflow path (E2) is designed such that a section thereof runs opposite to a section of the first inflow path (E1), impinging on the latter or intersecting the section of the first inflow path (E1).

Description

Description

Detergent dispenser drawer

The invention relates to a detergent dispenser and in particular to a

Detergent dispenser for a water-using household appliance.

A common detergent dispenser is essentially a container closed on three sides. The bottom slopes towards the fourth open side.

Water is supplied from above the floor via one or more nozzles.

Usually, the nozzles are adjusted so that all surfaces of the

The water then flows through the

The slope of the floor supports the open side.

To fill the detergent dispenser, the

Detergent dispenser drawer is pulled out of the appliance like a drawer and after

Push it back in to fill.

At low water pressures or flow rates, as well as when the detergent is clumped or caked on, residues of the detergent may remain in the dispenser drawer. This particularly applies to powdered detergents.

Therefore, there is a need to create a detergent dispenser that

Detergent residues in the dispenser drawer are reliably removed.

According to the invention, this problem is solved by a detergent dispenser with the

Features of patent claim 1. Advantageous embodiments and further developments of the invention are the subject of the dependent claims.

A detergent dispenser drawer according to the invention of a water-conducting household appliance has a detergent compartment with a base and a first inflow path, which leads from a water distribution device arranged vertically above the base into the

detergent compartment and further along the floor into an inlet.

The water distribution device is configured to allow water to flow into the detergent compartment. A second inflow path is designed such that a portion thereof is opposite to a portion of the first inflow path, impinging on the latter or the

Section of the first inflow path runs intersecting.

Due to the second inflow path, a section of which is directed onto a section of the first

inflow path or intersects the section of the first inflow path, the water flow is swirled, which can reliably remove detergent residues.

The floor can advantageously be designed as a sloping floor.

Due to the inclination of the ground, a point of impact or intersection of the two

Inflow paths can be influenced in such a way that the cleaning effect is improved.

Advantageously, the detergent compartment can be designed in the manner of a drawer and can be inserted into the detergent dispenser drawer.

According to this design, the detergent compartment is simply filled with a powdered

detergent, while other components such as the

Water distribution system does not interfere with the filling of the detergent.

Advantageously, the second inflow path can be defined by a secondary inflow space which is separated from the detergent compartment by a partition wall spaced from the floor.

According to this design, in the area between the partition wall and the floor of the

detergent compartment to a collision of the two inflow paths, whereby the

Turbulence of the incoming water occurs at the edge of the floor where most detergent usually accumulates.

Advantageously, at a bottom of the inlet in the area between the bottom and

A deflection must be provided in the partition wall to direct the second inflow path towards the

detergent compartment.

With such a deflection, for example in the form of a threshold or a

The triangular cross-section at the bottom of the inlet allows the water flow of the second inflow path to be directed directly to the edge of the bottom, ensuring an effective meeting of the two water flows.

Advantageously, a control means can be provided which is used to set a

Flow velocity and/or flow quantity and/or supply time of water flowing into the first flow path or second flow path.

With such a control device, the water supply in both flow paths can be controlled precisely. This makes it possible to only open the second flow path towards the end of the

This allows for targeted water supply during the inflow process, only then to remove detergent residues. Furthermore, unnecessary water consumption is avoided. The water distribution device can advantageously be located on the detergent dispenser drawer.

In this case, the water distribution device is configured to be connected to a water supply of the water-using household appliance. This is especially the case

Case when the detergent compartment is fully pushed in after filling with washing powder. In addition, a water supply means may be provided which is configured to allow water to flow into a secondary inflow space which defines the second

inflow path is formed.

With such a detergent dispenser, existing water-bearing

Household appliances can be retrofitted so that even older machines can be reliably cleaned of adhering washing powder residues.

Advantageously, the water supply means is also configured to be connected to the water distribution device or the water supply of the water-conducting household appliance.

Depending on the design, it may be advantageous to have a water supply system that supplies the second

The inlet pipe is connected to the water distribution system of the detergent dispenser drawer. Alternatively, a separate connection can be made directly to the water supply of the water-using household appliance.

As a water-conducting household appliance according to the invention, in particular

Washing machines, washer-dryers or dishwashers.

An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. In the drawings:

Fig. 1 is a sectional view of a detergent dispenser according to the invention;

Fig. 2 is a sectional view according to Fig. 1 showing

Flow conditions in the detergent compartment and an inlet;

Fig. 3 is a view similar to Fig. 2 illustrating the operation of the invention;

Fig. 4 is a representation according to Fig. 3 with a modification.

Fig. 1 shows a schematic structure of a detergent dispenser according to the embodiment. The detergent dispenser has a detergent compartment 1 with a

Bottom 13, which is designed to slope in an insertion direction of the detergent compartment 1.

A powdered washing powder 12 can be stored in the detergent compartment 1.

A water distribution device 15 is provided above the floor 13. Below the floor there is an inlet 19 to the interior of the water-bearing

household appliance, e.g. a washing machine, a washer-dryer or a

Dishwasher, through which the detergent rinsed from the detergent drawer is then fed together with water as lye into the interior of the water-bearing household appliance. 5

The detergent compartment is limited by a partition 18 which is located between the

Detergent compartment 1 and a second inflow chamber 17 defined by the partition wall. Between an edge of the sloping floor 13 and the partition wall 18 there is an opening through which the rinsed-out detergent is conveyed into the inlet 19.

From Fig. 2 the flow conditions with activated water supply in the

Detergent compartment 1. The small arrows indicate water flowing from the

Water distribution device 15 to the floor 13 and the side walls of the ı5 detergent compartment 1. This essentially creates a water flow E1, which in the

Fig. 2 is shown by a dashed arrow.

In order to reliably rinse out detergent residues 12a remaining on the floor, according to the embodiment, a second water flow E2 can be passed through the second

Inflow chamber 17. This second water flow is indicated in Fig. 3 by a dashed arrow E2.

The two water flows E1 and E2 meet in the space between the partition wall 18 and the edge of the bottom 13, causing a turbulence of the

These turbulences reliably eliminate the

Detergent residues 12a located on the edge of the base 13.

For improved guidance of the second flow E2, according to a modification of the

A threshold 21 is provided at the bottom of the inlet 19, through which the water flow E2 is directed upwards toward the edge of the bottom 13. This can be seen in Fig. 4.

This results in a reliable cleaning of detergent residues in the

Detergent compartment 1.

According to a preferred modification, a control device is provided by which at least the second flow can be switched on and off in a targeted manner.

Cleaning effect as well as the drainage of the lye can be improved.

According to a further modification, one or more sensors are provided which

Detect accumulation of detergent residues 12a and trigger a

Activate cleaning process.
