Abstract

A kitchen ensemble includes one or more appliances and one or/more cabinets. Some or all of the appliances and cabinets have windows made of a material having a controllable opacity. The windows are opaque in the normal state, but can be made transparent by operation of a suitable control. Therefore, one can view the contents of the cabinets and/or appliances without opening any doors. The invention therefore enhances the convenience of using the kitchen, and saves energy by minimizing the number of times a refrigerator or range door is opened. It also enhances the aesthetic qualities of the kitchen.

Claims

1. A kitchen ensemble having at least one appliance and at least one cabinet, said at least one appliance having a window and said at least one cabinet having a window, the appliance and cabinet defining interior regions and a common exterior region, the windows being permanently exposed to said common exterior region, said windows being made of a material of controllable opacity, wherein said windows are substantially clear in a first state and substantially opaque in a second state, and means for changing the states of said windows.

2. The ensemble of claim 1, wherein the changing means affects all of the windows in the kitchen.

3. The ensemble of claim 1, wherein the changing means affects fewer than all of the windows in the kitchen.

4. The ensemble of claim 1, wherein there are at least two distinct changing means for two windows, wherein one window can change state without affecting another window.

5. The ensemble of claim 1, wherein the controllable opacity material comprises a polymer-dispersed liquid crystal.

6. The ensemble of claim 5, wherein the polymer-dispersed liquid crystal is controlled by control means selected from the group consisting of electrical control means, ultrasonic control means, infrared control means, photoelectric control means, remote control means, auditory control means, and motion sensing control means.

7. The ensemble of claim 1, wherein the changing means includes a controller mounted to at least one of said appliance and said cabinet.

8. The ensemble of claim 1, wherein at least one of the windows has a frame, and wherein the changing means is mounted in said frame.

9. The ensemble of claim 1, wherein at least one appliance has a door, and wherein the changing means comprises a handle for said door.

10. A kitchen ensemble having a set of appliances and a set of cabinets, the appliances including at least a range and a refrigerator, wherein the refrigerator has a door with a window disposed in said door, wherein a plurality of the cabinets have windows disposed therein, the appliances and cabinets defining interior regions and a common exterior region, the windows being permanently exposed to said common exterior region wherein all of said windows are made of a material having a controllable opacity, and means for controlling the opacity of each of the windows, wherein contents of the refrigerator and of the cabinets can be viewed without opening any of the doors.

11. The ensemble of claim 10, wherein the controlling means affects all of the windows in the ensemble.

12. The ensemble of claim 10, wherein there are at least two distinct controlling means for two windows, wherein one window can change state without affecting another window.

13. The ensemble of claim 10, wherein the controllable opacity material comprises a polymer-dispersed liquid crystal.

14. The ensemble of claim 10, wherein the controlling means includes a controller mounted to at least one of said appliances and said cabinets.

15. A method of using a kitchen, the method comprising the steps of:

a) providing a plurality of kitchen components, the kitchen components being selected from the group consisting of appliances and cabinets, wherein at least some of said components have windows, the appliances and cabinets defining interior regions and a common exterior region, the windows being permanently exposed to said common exterior region, wherein at least some of the windows are made of a material having a controllable opacity, wherein said material is normally substantially opaque, and

b) periodically activating a controller to change the opacity of said material, thereby making at least some of the windows transparent while the controller is activated.

16. The method of claim 15, wherein the controller affects all of the windows in the kitchen.

17. The method of claim 15, wherein there are at least two distinct controllers for two windows, wherein one window can change state without affecting another window.

18. The method of claim 15, wherein the controllable opacity material comprises a polymer-dispersed liquid crystal.

19. A display apparatus comprising a plurality of windows, each window being made of a material having a controllable opacity, and a computer, the computer being connected to control simultaneously the opacity of all of said windows according to a predetermined program, wherein the computer comprises means for storing a pattern, and for reproducing said pattern by simultaneous control of opacities of selected windows.

20. The apparatus of claim 19, wherein the controllable opacity material comprises a polymer-dispersed liquid crystal.

21. The apparatus of claim 19, wherein the windows are disposed on a billboard.

22. The apparatus of claim 19, wherein the windows are disposed on a building.

23. A method of creating a display, the method comprising the steps of:

a) providing a structure having a plurality of windows, each window being made of a material having an individually controllable opacity,

b) simultaneously controlling opacities of selected ones of said windows, so as to reproduce a stored pattern.

24. The method of claim 23, wherein the structure comprises a billboard.

25. The method of claim 23, wherein the structure comprises a building.

26. A kitchen ensemble having at least one appliance and at least one cabinet, said at least one appliance having a window and said at least one cabinet having a window, said windows being made of a material of controllable opacity, wherein said windows are substantially clear in a first state and substantially opaque in a second state, and means for changing the states of said windows, wherein the changing means includes a controller mounted to at least one of said appliance and said cabinet.

27. A kitchen ensemble having at least one appliance and at least one cabinet, said at least one appliance having a window and said at least one cabinet having a window, said windows being made of a material of controllable opacity, wherein said windows are substantially clear in a first state and substantially opaque in a second state, and means for changing the states of said windows, wherein at least one of the windows has a frame, and wherein the changing means is mounted in said frame.

28. A kitchen ensemble having at least one appliance and at least one cabinet, said at least one appliance having a window and said at least one cabinet having a window, said windows being made of a material of controllable opacity, wherein said windows are substantially clear in a first state and substantially opaque in a second state, and means for changing the states of said windows, wherein at least one appliance has a door, and wherein the changing means comprises a handle for said door.

29. A kitchen ensemble having a set of appliances and a set of cabinets, the appliances including at least a range and a refrigerator, wherein the refrigerator has a door with a window disposed in said door, wherein a plurality of the cabinets have windows disposed therein, wherein all of said windows are made of a material having a controllable opacity, and means for controlling the opacity of each of the windows, wherein contents of the refrigerator and of the cabinets can be viewed without opening any of the doors, wherein the controlling means includes a controller mounted to at least one of said appliances and said cabinets.

30. A kitchen appliance having a window, the appliance defining an interior region and an exterior region, the window being permanently exposed to the exterior region, the window being made of a material of controllable opacity, wherein the window is substantially clear in a first state and substantially opaque in a second state, and means for manually changing the state of the window.
