Abstract

A dispenser system is provided, comprising a dispenser head (3), a feeding jet for water (7) at the dispenser head, and a reservoir immediately above the dispenser head for material to be dispensed, wherein an external supply of water is fed to a tank (4) arranged at a predetermined head above the dispenser head (3), wherein a feeding line (9) connects the tank (4) to the feeding jet (7), and wherein variations of flow to the tank (4) are accommodated by means of an overflow line (10) from the tank to a flushing jet (10) at the dispenser head, such that the water at the feeding jet (7) is always at a known pressure. This dispenser system was found to be a flexible arrangement in which low water pressures and/or varying water pressures can be adequately accomodated.

Claims

1. A dispenser system, comprising a dispenser head (3), a feeding jet for water (7) at the dispenser head, and a reservoir immediately above the dispenser head for material to be dispensed, wherein an external supply of water is fed to a tank (4) arranged at a predetermined head above the dispenser head (3), wherein a feeding line (9) connects the tank (4) to the feeding jet (7), and wherein variations of flow to the tank (4) are accommodated by means of an overflow line (10) from the tank to a flushing jet (10) at the dispenser head, such that the water at the feeding jet (7) is always at a known pressure.

2. A dispenser system according to claim 1, wherein a container (2) of solid detergent material having a dispensing cap (6) is placed in an inverted manner in the reservoir.

3. A dispenser system according to claim 1, wherein the feeding jet (7) has a substantially horizontal direction.

4. A dispensing system according to claim 2, wherein the feeding jet feeds water into the dispensing cap (6) through an aperture (8), when in operation.

5. A dispensing system according to claim 1, wherein the external supply of water fed to tank (4) is controlled by solenoid (12).

6. A dispenser system according to claims 1, wherein the end of the overflow line (10) in tank (4) is arranged at a higher position than the end of the feeding line (9).

7. A dispenser system according to claim 1, wherein an aperture (17) is provided at the bottom of the overflow line (10), inside tank (4).

8. A dispenser system according to claim 1, wherein tank (4) is equipped with a mesh or foam pad (15) to avoid excess splashing.
