Abstract

A system including an enclosure of a washing machine, a drum within the enclosure, a mixing unit, within the enclosure but separate from the drum and in fluid communication with the drum, a water supply unit coupled to the mixing unit, a reservoir having a conduit fluidly coupled to the mixing unit, and a container connecting assembly configured to fix a spout of a container to the reservoir. An apparatus including a reservoir, external to a washing machine, to receive a liquid wash aid, a container connecting assembly coupled to the reservoir and configured to fix a spout of a container containing liquid wash aid to the reservoir, a flexible conduit to pass liquid wash aid from the reservoir to the washing machine, and a wash aid control unit connected to the flexible conduit and adapted to meter a flow of liquid wash aid from the reservoir to the washing machine.

Claims

1. A system, comprising:

an enclosure;

a drum housed within the enclosure;

a mixing unit, housed within the enclosure, separate from the drum, and in fluid communication with the drum;

a water supply unit coupled to the mixing unit;

a reservoir having a conduit configured to fluidly couple the reservoir to the mixing unit;

a supply module provided on a top surface of the enclosure, receiving a container on a top surface thereof, and having a spout inlet to receive a spout of the container;

a hinge assembly configured to couple the supply module to the enclosure so that the supply module can be tilted with respect to the top surface of the enclosure;

a support unit rotatably coupled to an underside of the supply module and configured to support the supply module in the tilted state;

a container connecting assembly provided on the top surface of the supply module near the spout inlet and configured to fix the spout of a container to the spout inlet; and

a reservoir receiving portion, connected to the underside of the supply module corresponding to the spout inlet, having a threaded exterior portion,

wherein the reservoir has a threaded interior portion which mates with the threaded exterior portion of the reservoir receiving portion so that the reservoir is removably connected to the reservoir receiving portion.

2. The system of claim 1, wherein the mixing unit is a removable or a non-removable wash aid box.

3. The system of claim 1, wherein the reservoir is external to the enclosure.

4. The system of claim 1, wherein the container connecting assembly is further configured to maintain a valve of the container in an open position, to permit an unimpeded flow of the container'"'"'s contents into the reservoir, when the spout of the container is fixed to the reservoir.

5. The system of claim 1, further comprising a pump configured to transfer a metered volume of liquid from the reservoir to the mixing unit.

6. The system of claim 1, wherein a top surface of the supply module is configured to:

receive the container in an integrally formed recess, and

maintain the container at an altitude such that gravity will cause the container'"'"'s liquid contents to flow out of the container'"'"'s spout, to make the container empty of or near empty of its liquid contents.

7. The system of claim 1, further comprising:

a water supply valve through which wash water may be introduced from an external water source connecting to the mixing unit; and

a wash aid box slidingly engaged within the enclosure connected to the mixing unit by a first water supply passage.

8. The system of claim 1, wherein the reservoir is partially or entirely transparent, to permit observation of a level of the reservoir'"'"'s contents.

9. The system of claim 1, further comprising a concentration selection unit provided to select the concentration of a liquid contained in the container.
