Abstract

An embodiment of the present invention is directed to an automated laundry system. The system includes a number of perforated clothes drums, each of which holds a single load of laundry, and a washer/dryer unit. The washer/dryer unit includes a loading rack for queuing the drums for subsequent washing, a clothes washing component adapted to sequentially receive the drums from the loading rack and wash the respective loads of laundry therein, a clothes drying component adapted to sequentially receive the drums from the clothes washing component and dry the loads of laundry therein, and a holding rack for sequentially receiving the drums from the clothes drying component and holding the drums for a period of time.

Claims

1. An automated laundry system comprising:

a plurality of perforated clothes drums, each of the drums for holding a single load of laundry; and

a washer/dryer unit comprising;

a loading rack for queuing the drums for subsequent washing;

a clothes washing component adapted to sequentially receive the drums from the loading rack and wash the respective loads of laundry therein;

a clothes drying component adapted to sequentially receive the drums from the clothes washing component and dry the loads of laundry therein; and

a holding rack for sequentially receiving the drums from the clothes drying component and holding the drums for a period of time,

wherein the clothes washing component comprises a first set of transfer rails orientable between a first orientation for receiving the drums from the loading rack and a second orientation for transmitting the drums to the clothes drying component, and

wherein the clothes drying component comprises a second set of transfer rails orientable between a first orientation for receiving the drums from the clothes washing component and a second orientation for transmitting the drums to the holding rack.

2. The automated laundry system as recited in claim 1 wherein the perforated clothes drums comprise wire-mesh cylinders.

3. The automated laundry system as recited in claim 1 wherein the perforated clothes drums include removable lids.

4. The automated laundry system as recited in claim 1 wherein the washer/dryer unit further comprises a trap-door disposed between the loading rack and the clothes washing component.

5. The automated laundry system as recited in claim 1 wherein the washer/dryer unit further comprises a trap-door disposed between the clothes washing component and the clothes drying component.

6. The automated laundry system as recited in claim 1 wherein the washer/dryer unit further comprises a trap-door disposed between the clothes drying component and the holding rack.

7. The automated laundry system as recited in claim 1 wherein the washer/dryer unit further comprises a reservoir for storing a laundry fluid.

8. The automated laundry system as recited in claim 7 wherein the laundry fluid is selected from the group consisting of laundry detergent, fabric softener and bleach.

9. The automated laundry system as recited in claim 7 wherein the clothes washing component is operable to dispense an appropriate amount of the laundry fluid during a wash cycle, based at least in part on a user-adjustable washing parameter.

10. The automated laundry system as recited in claim 1 wherein the loading rack is at least partially inclined so as to urge the drums towards the clothes washing component.

11. The automated laundry system as recited in claim 1 wherein the holding rack is at least partially inclined so as to urge the drums away from the clothes drying component.

12. The automated laundry system as recited in claim 1 further comprising:

a memory for storing a laundry program for each of the drums; and

a controller coupled to the clothes washing and clothes drying components, the controller adapted to cause the clothes washing and clothes drying components to, respectively, wash and dry each of the loads of laundry in the drums according to a respective one of the laundry programs.

13. The automated laundry system as recited in claim 12, comprising a user interface configured to receive input defining a laundry program for each of the drums.

14. In the automated laundry system of claim 1, a method for washing multiple loads of laundry, comprising:

providing a memory for storing washing and drying settings corresponding to each of the loads held in the plurality of perforated clothes drums;

providing a user interface having a display;

receiving first washing and drying settings corresponding to a first load of laundry via the user interface;

storing the first washing and drying settings in the memory;

receiving second washing and drying settings corresponding to a second load of laundry via the user interface;

storing the second washing and drying settings in the memory;

washing the first load of laundry according to the first washing and drying settings;

drying the first load of laundry according to the first washing and drying settings;

washing the second load of laundry according to the second washing and drying settings; and

drying the second load of laundry according to the second washing and drying settings.

15. The method as recited in claim 14 wherein the second washing and drying settings at least partially differ from the first washing and drying settings.

16. The method as recited in claim 14 further comprising:

receiving, via the user interface, an indication of a number of loads of laundry to be washed.

17. The method as recited in claim 14 further comprising:

successively soliciting, via the user interface, washing and drying settings for each of the number of loads of laundry to be washed.

18. The method as recited in claim 14 wherein washing the first load of laundry according to the first washing and drying settings comprises:

dispensing an appropriate amount of detergent into the washer based on the first washing and drying settings.

19. The method as recited in claim 14 wherein washing the second load of laundry according to the second washing and drying settings comprises:

washing the second load of laundry for a period of time while the first load of laundry is simultaneously being dried.

20. An automated laundry system comprising:

a loading component operable to queue at least two drums of individual, separated loads of laundry;

a washing component operable to receive from the loading component, and wash, in succession, each of the at least two loads, wherein the drums are received at the washing component from the loading component in a direction perpendicular to a rotational axis of the drums;

a drying component operable to receive from the washing component, dry, and eject from the drying component, in succession, each of the at least two loads;

a memory configured to store at least two laundry programs, each of the at least two laundry programs associated with a respective one of the queued at least two individual, separated loads of laundry; and

a controller coupled to the washing and drying components, the controller configured to cause the washing and drying components to, respectively, wash and dry each of the at least two loads according to a respective one of the at least two laundry programs.

21. The automated laundry system as recited in claim 20:

wherein the washing component comprises a first set of transfer rails orientable between a first orientation for receiving the drums from the loading component and a second orientation for transmitting the drums to the drying component, and

wherein the drying component comprises a second set of transfer rails orientable between a first orientation for receiving the drums from the clothes washing component and a second orientation for ejecting the drums from the drying component.

22. The automated laundry system as recited in claim 20, comprising a user interface configured to receive input defining each of the at least two laundry programs associated with the respective one of the queued at least two drums of individual, separated loads of laundry.
