Abstract

A function indicator system for displaying the control settings related to functions and features of an electric fireplace. The function indicator system can feature a function indicator module, a controller communicatively connected to the function indicator module, and a power source electrically connected to the function indicator module. The function indicator module can contain a plurality of light sources that emit paths of light, which can pass through control status indicia to create a visual display on an exterior surface of a projection screen of the electric fireplace. The visual display is visible to a viewer so as to alert the viewer as to the particular status of a control setting of the electric fireplace such as, for example, the temperature of heat produced, the brightness of simulated flames, or the length of time that the user desires for the electric fireplace to operate prior to automatic shutdown.

Claims

1. A system for displaying the control settings for an electric fireplace, the system comprising:

an electric fireplace comprising a non-electric projection screen;

a function indicator module with at least one function indicator light installed approximately adjacent to an interior surface of the non-electric projection screen for creating a non-video visual status display of the electric fireplace'"'"'s control settings that is projected onto the non-electric projection screen such that the non-video visual status display and function indicator module are substantially hidden from view when the at least one function indicator light is not illuminated;

a controller communicatively connected to the function indicator module to control a dimmable brightness of light emitted by the at least one function indicator light; and

a power source;

wherein at least part of the visual status display is viewable from an exterior surface of the non-electric projection screen when the at least one function indicator light is illuminated;

wherein the non-video visual status display comprises patterns or shapes comprised of light that passes through or around a visual display apparatus and is projected onto the non-electric projection screen.

2. The system of claim 1, wherein the at least one function indicator light emits a path of light.

3. The system of claim 2, wherein the at least one function indicator light comprises a light-emitting diode.

4. The system of claim 2, wherein the non-video visual status display of the at least one function indicator light comprises patterns or shapes corresponding to at least one of the following settings:

power, temperature, light brightness, blower or fan speed, timer, flame control, and speaker volume.

5. The system of claim 1, wherein the function indicator module varies the non-video visual status display displayed on the non-electric projection screen based upon a user'"'"'s selection of control settings levels.

6. The system of claim 1, wherein the function indicator module comprises:

a housing comprising an open end and a closed end;

at least one function indicator light installed on an interior surface of the closed end of the housing; and

the visual display apparatus installed over the open end of the housing.

7. The system of claim 6, wherein the visual display apparatus comprises a translucent film comprising printed control status indicia.

8. The system of claim 6, wherein the visual display apparatus comprises an opaque plate comprising at least one translucent section in alignment with a path of light emitted by the at least one function indicator light.

9. The system of claim 8, wherein the at least one translucent section comprises printed control status indicia.

10. The system of claim 6, wherein the visual display apparatus comprises an opaque plate comprising at least one aperture aligned with a path of light emitted by the at least one function indicator light.

11. The system of claim 10, wherein the opaque plate comprises control status indicia positioned within the path of light passing through the at least one aperture.

12. The system of claim 1, wherein the function indicator module is installed behind an interior surface of the non-electric projection screen to project the non-video visual status display onto the interior surface of the non-electric projection screen.

13. The system of claim 1, wherein the function indicator module is installed on an interior surface of the non-electric projection screen.

14. The system of claim 1, wherein the function indicator module is connected to a timer-controlled dimmer to control the dimmable brightness of the light.

15. The system of claim 1, wherein the controller comprises a user control interface comprising at least one set of control features selected from the group consisting of:

control buttons, a touchscreen comprising electronically displayed control keys, and a remote control.

16. The system of claim 1, wherein the controller is a computer comprising a user control interface with control features.

17. The system of claim 1, wherein the controller is a circuit board comprising input and output ports to which the function indicator module is electrically and communicatively connectable.

18. A method for visually displaying the control settings of an electric fireplace, the method comprising the steps of:

(a) projecting light emitted by a light source through a function indicator module comprising control status indicia;

(b) projecting light passing through the control function indicator module onto a non-electric projection screen of an electric fireplace to create a non-video visual display of the electric fireplace'"'"'s control settings on an exterior surface the non-electric projection screen;

(c) varying the characteristics of the non-video visual display depending upon input from a user controlling the electric fireplace'"'"'s control settings;

(d) projecting the visual display onto an interior surface of the non-electric projection screen for a predetermined period of time determinable by programming of a timer-controlled dimmer; and

(e) dimming the light source creating the visual display after a predetermined period of time until the light source is turned off and the non-video visual display disappears from the exterior surface of the non-electric projection screen;

wherein the at least part of the non-video visual status display is viewable from an exterior surface of the non-electric projection screen when at least part of the function indicator module is illuminated;

wherein the non-video visual status display comprises patterns or shapes comprised of light that passes through or around a visual display apparatus and is projected onto the interior surface of the non-electric projection screen so as to be visible on the exterior surface of the non-electric projection screen.
