[Hardware structure of gas stove fire power luminous indicator device]

Please refer to Figure 1, which is a block diagram of a gas stove fire power luminous indicator device according to an embodiment of the present invention. The gas stove fire power luminous indicator device 1 described herein is, for example, for use in a gas stove and can be used in conjunction with a fire power control member of the gas stove to display corresponding light signals representing different fire powers.

In one embodiment, the gas stove fire power luminous indicator device 1 includes, for example, but is not limited to, a control circuit 10, a detection circuit 12, and a light module 14. The control circuit 10 is electrically connected to the detection circuit 12 and the light module 14, respectively, wherein the detection circuit 12 detects the size of the fire state and outputs a fire power indication signal. The control circuit 10 controls the light module 14 to display a fire power light signal related to the fire state according to the fire power indication signal provided by the detection circuit 12. And the fire power light signal presents different lights according to the different fire power sizes of the fire.

For example, when the firepower indication signal represents a first firepower, the control circuit 10 controls the light module 14 to emit a first firepower light signal. When the firepower indication signal represents a second firepower, the control circuit 10 controls the light module 14 to emit a second firepower light signal. When the firepower indication signal represents a third firepower, the control circuit 10 controls the light module 14 to emit a third firepower light signal. The first firepower is greater than the second firepower, and the second firepower is greater than the third firepower. The first firepower light signal, the second firepower light signal, and the third firepower light signal can display different light signals of different colors or different light signals of light-emitting elements at different positions. The number of light signals of the first firepower light signal, the second firepower light signal, and the third firepower light signal are only given as examples and are not intended to limit the present invention. When the present invention is actually implemented, the number of display lights and different presentation methods can be set correspondingly according to the different fire sizes of the gas stove.

In one embodiment, the control circuit 10 is electrically connected to a fire control member 16, an ignition circuit 17, a flame detection circuit 18, and a temperature detection circuit 19. The control circuit 10 can perform ignition-related operations relative to the ignition circuit 17 according to the operation of the fire control member 16. The fire control member mentioned here is, for example, a fire knob of a gas stove, that is, a person can perform the ignition operation of the gas stove by operating the fire knob. The ignition circuit 17 mentioned here is controlled by the control circuit 10 and can be used to provide an ignition signal of the gas stove to ignite or turn off the fire of the gas stove.

For example, when the control circuit 10 obtains an ignition operation through the power knob and determines that the ignition operation is to turn on the fire, the control circuit 10 controls the ignition circuit 17 to turn on the ignition signal to ignite the fire of the gas stove. Then, the control circuit 10 can obtain the fire status of the gas stove (such as whether the fire is ignited and the size of the fire, etc.) through the flame detection circuit 18. The flame detection circuit described here is, for example, a thermocouple, which can detect the fire status through the thermocouple and output a flame signal accordingly. At this time, the control circuit 10 can control the light module 14 to output a corresponding fire power light signal according to the current fire status.

On the other hand, when the control circuit 10 obtains an ignition operation through the fire knob and determines that the ignition operation is to turn off the fire, the control circuit 10 controls the ignition circuit 17 to turn off the fire of the gas stove. Then, the control circuit 10 can know the fire status of the gas stove (such as whether the fire is extinguished) through the flame detection circuit 18. At this time, the control circuit 10 controls the light module 14 to output the corresponding fire light signal according to the current fire extinguishing status. For example, when the fire is extinguished, the light module 14 stops displaying the fire light signal.

In one embodiment, the control circuit 10 can obtain the temperature of the pot on the stove through the temperature detection circuit 19, and can control the fire power of the stove according to the pot temperature, but the present invention is not limited to this.

It is worth noting that the detection technology used by the detection circuit 12 can be, for example, external detection or internal detection. The external detection mentioned here refers to the detection of the fire adjustment behavior of the gas furnace by the detection personnel, and the internal detection refers to the detection of the fire of the gas furnace. In other words, the detection circuit 12 can obtain the fire status of the gas furnace through these two different detection methods. The possible implementation methods of the detection circuit 12 will be described in detail later.

In one embodiment, the control circuit 10 can also control the light module 14 to stop displaying the power light according to an abnormal signal, and control the light module 14 to display an abnormal light, such as a flashing light or no display (i.e., the light module 14 does not display). How the control circuit 10 obtains the abnormal signal is known to those skilled in the art, so it will not be described in detail here.

Please refer to Figures 2 and 3. Figure 2 is another block diagram of a gas stove fire power luminous indicator device according to an embodiment of the present invention, and Figure 3 is a schematic diagram of a light module having multiple light emitting elements according to an embodiment of the present invention. The gas stove fire power luminous indicator device 1A described in Figure 2 is another embodiment of the detection circuit 12 and the light module 14 in Figure 1, and only the differences are described here.

In one embodiment, the detection circuit 12A shown in FIG2 may be a positioning detector 121. The positioning detector 121 described herein detects different firepower operation positions of a firepower control member (firepower knob), and may output a corresponding firepower indication signal according to the detection result.

For example, when the fire knob is rotated to the first fire position by the personnel, the fire indication signal output by the positioning detector 121 at this time belongs to the first fire indication signal. When the fire knob is rotated to the second fire position by the personnel, the fire indication signal output by the positioning detector 121 at this time belongs to the second fire indication signal. When the fire knob is rotated to the third fire position by the personnel, the fire indication signal output by the positioning detector 121 at this time belongs to the third fire indication signal. When the positioning detector 121 detects that the fire knob is at other different fire positions, the same method can be used.

In one embodiment, the light module 14A can be as shown in FIG. 3 , and the light module 14A includes, for example, a light plate 141, and a plurality of light elements 142 are arranged on the light plate 141. The light plate 141 is formed with a mounting hole 1411 for the fire knob 161, and the light elements 142 are arranged around one side of the mounting hole. Therefore, the control circuit 10 can control the light elements 142 to display different fire light signals according to the detection result of the position detector 121.

For example, when the positioning detector 121 outputs a first fire power indication signal, the control circuit 10 controls the first light emitting element in the light emitting element 142 to display a first fire power light signal. When the positioning detector 121 outputs a second fire power indication signal, the control circuit 10 controls the second light emitting element in the light emitting element 142 to display a second fire power light signal. When the positioning detector 121 outputs a third fire power indication signal, the control circuit 10 controls the third light emitting element in the light emitting element 142 to display a third fire power light signal. The light module 14A can display other different fire power light signals in this manner, but the present invention is not limited thereto.

In one embodiment, the light module 14A displays different fire power light signals. In addition to the display by the light elements 142 at different locations, the light colors displayed by each light element 142 can be the same or different. The light element 142 described here is, for example, an LED light element.

In one embodiment, when the control circuit 10 controls the light module 14A to display an abnormal light signal, different abnormal light signals may be displayed according to different abnormal types. For example, when the abnormal light signal received by the control circuit 10 belongs to the first abnormal condition of the gas stove, the control circuit 10 controls the first light element in the light element 142 to display the first abnormal light signal. When the abnormal light signal received by the control circuit 10 belongs to the second abnormal condition of the gas stove, the control circuit 10 controls the second light element in the light element 142 to display the second abnormal light signal. When the abnormal light signal received by the control circuit 10 belongs to the third abnormal condition of the gas stove, the control circuit 10 controls the third light emitting element in the light emitting element 142 to display the third abnormal light signal. The light emitting module 14A can display other different abnormal light signals in the same manner.

In addition, it should be noted that the fire power light signal displayed in this light module 14A is displayed in a constant light mode, and the abnormal light signal is displayed in a flashing mode, that is, the display modes of the fire power light signal and the abnormal light signal are different from each other, so that personnel can more easily identify them without confusion.

Please refer to Figures 4 and 5. Figure 4 is another block diagram of a gas stove fire power luminous indicator device according to an embodiment of the present invention, and Figure 5 is a schematic diagram of a light-emitting module that emits light through a light guide according to an embodiment of the present invention. The gas stove fire power luminous indicator device 1B described in Figure 4 is another embodiment of the detection circuit 12 and the light-emitting module 14 in Figure 1, and only the differences are described here.

In one embodiment, the detection circuit 12B shown in FIG4 may be a voltage detector 123. The voltage detector 123 described herein detects the flame signal output by the flame detection circuit 18, and may output a corresponding fire power indication signal according to the detection result.

For example, the fire power indication signal can be regarded as a fire power voltage value, and the fire power voltage value varies with different flame sizes. Therefore, when the fire power knob is rotated to the first fire power position by the staff, the fire power voltage value obtained by the control circuit 10 through the voltage detector 123 belongs to the first fire power voltage value. When the fire power knob is rotated to the second fire power position by the staff, the fire power voltage value obtained by the control circuit 10 through the voltage detector 123 belongs to the second fire power voltage value. When the fire power knob is rotated to the third fire power position by the staff, the fire power voltage value obtained by the control circuit 10 through the voltage detector 123 belongs to the third fire power voltage value. The voltage detector 123 can be used in the same manner to detect other flame sizes.

In one embodiment, the light module 14B may be as shown in FIG. 5 , the light module 14B may include, for example, a light guide plate 145 and a side light module 146, the side light module 146 is disposed adjacent to one side of the light guide plate, and the side light module 146 has at least one light emitting element, and the light guide plate 145 is formed with a mounting hole 1451 for the power knob 161 to be disposed. Here, the light emitting element may be, for example, a three primary color (RGB) light emitting element or a two-color light emitting element. Therefore, when the light emitting element of the side light module 146 is illuminated, the light guiding effect of the light guide plate 145 may be passed through, and a uniform surface light source may be displayed by the light emitting surface of the light guide plate 145.

Specifically, when the voltage detector 123 outputs a first fire voltage value, the control circuit 10 controls the light module 14B to display a first fire light signal. When the voltage detector 123 outputs a second fire voltage value, the control circuit 10 controls the light module 14B to display a second fire light signal. When the voltage detector 123 outputs a third fire voltage value, the control circuit 10 controls the light module 14B to display a third fire light signal. The light module 14B can display other different fire light signals in the same manner.

In one embodiment, when the sidelight module 146 is a three-primary color (RGB) light-emitting element, different colors of light can be mixed through light mixing technology. Therefore, the different fire power light signals displayed by the aforementioned light module 14B can be distinguished by displaying different colors of light. For example, when the fire is high, the light module 14B can display a red light signal; when the fire is medium, the light module 14B can display an orange light signal; when the fire is low, the light module 14B can display a yellow light signal. This is just an example and is not intended to limit the present invention.

In one embodiment, when the sidelight module 146 is a dual-color light-emitting element, for example, when the fire is successfully ignited, the light-emitting module 14B may display a blue light signal, and when the fire fails to ignite or is extinguished, the light-emitting module 14B may not display any light signal. This is only an example and is not intended to limit the present invention.

In one embodiment, when the control circuit 10 controls the light module 14B to display an abnormal light signal, different abnormal light signals may be displayed according to different abnormal types. For example, when the abnormal light signal received by the control circuit 10 belongs to the first abnormal condition of the gas stove, the control circuit 10 controls the light element in the side light module 146 to display the first abnormal light signal. When the abnormal light signal received by the control circuit 10 belongs to the second abnormal condition of the gas stove, the control circuit 10 controls the light element in the side light module 146 to display the second abnormal light signal. When the abnormal light signal received by the control circuit 10 belongs to the third abnormal condition of the gas stove, the control circuit 10 controls the light-emitting element in the side light module 146 to display the third abnormal light signal. The light module 14B can display other different abnormal light signals in the same manner.

In addition, it should be noted that the fire power light signal described herein, for example, is displayed by the light module 14B in a constant-brightness uniform surface light source manner, and the abnormal light signal herein, for example, is displayed by the uniform surface light source of the light module 14B in a flashing manner, and different types of abnormalities can be represented by light signals with different flashing frequencies or different flashing colors, that is, the display methods of the fire power light signal and the abnormal light signal are different from each other, so that personnel can more easily identify them without confusion.

Please refer to Fig. 6, which is a gas stove fire power luminous indicating device with self-detection according to an embodiment of the present invention. The gas stove fire power luminous indicating device 1C described in Fig. 6 is another embodiment of the detection circuit 12 in Fig. 1, and only the differences are described here.

In one embodiment, the detection circuit 12C described in FIG. 6 includes the position detector 121 in FIG. 2 and the voltage detector 123 in FIG. 5 . The individual functional operations of the position detector 121 and the voltage detector 123 have been described above and will not be described in detail here. The purpose of setting two detectors in the detection circuit 12C is to confirm whether the detection results are consistent with each other. If the two detection results are consistent, it means that the two detectors are currently normal. If the two detection results are inconsistent, it may mean that one of the two detectors is abnormal.

For example, when the positioning detector 121 detects that the fire knob is rotated to the first fire position (such as the high fire position), and the fire voltage value detected by the voltage detector 123 is determined to be a high fire, the control circuit 10 determines that the detection results of the two detectors are consistent. At this time, the control circuit 10 can control the light module 14 to display the first fire light signal. Alternatively, when the positioning detector 121 detects that the fire knob is rotated to the second power position (such as the medium fire position), and the fire voltage value detected by the voltage detector 123 is determined to be the medium fire, the control circuit 10 determines that the detection results of the two detectors are consistent. At this time, the control circuit 10 can control the light module 14 to display the second fire light signal.

However, when the positioning detector 121 detects that the fire knob is rotated to the third fire position (such as the low fire position), and the fire voltage value detected by the voltage detector 123 is determined to be a medium fire, the control circuit 10 determines that the detection results of the two detectors are inconsistent, and determines that one of the two detectors may be abnormal. At this time, the control circuit 10 can control the light module 14 to display an abnormal light signal indicating that the detection circuit is abnormal, such as displaying or flashing a specific color light signal through one of the light emitting elements 142 of the light module 14 or the side light module 146.

In one embodiment, the light emitting module 14A in FIG. 2 may also be replaced by the light emitting module 14B in FIG. 4 ; and the light emitting module 14B in FIG. 4 may also be replaced by the light emitting module 14A in FIG. 2 .

[Gas stove fire power glow indication method]

Please refer to FIG7. FIG7 is a flow chart of the gas stove fire power luminous indication method provided by the embodiment of the present invention. The flow chart shown in FIG7 is used to illustrate the aforementioned structure, but is not limited thereto. The flow chart shown in FIG7 includes the following steps, for example.

In step S701, ignition is performed. When the operator starts the ignition of the gas stove by operating the fire knob, the control circuit 10 can control the ignition circuit 17 to provide an ignition signal to ignite the fire of the gas stove according to the control position of the fire knob.

In step S703, the ignition state is detected. When the fire is ignited, the control circuit 10 detects the fire state of the gas furnace through the detection circuit 12. For example, the position detector 121 can detect the fire operation position of the fire knob or the voltage detector 123 can detect the flame signal. The control circuit 10 can obtain the fire indication signal according to the detection result of the detection circuit 12.

In step S705, different fire power lights are displayed according to different fire power levels. When the control circuit 10 obtains the fire power indication signal, the control circuit 10 can know the current fire power level of the gas stove through the fire power indication signal, and control the light module 14 to display the corresponding fire power light. For example, when the fire power indication signal indicates that the fire is a high fire, the control circuit 10 controls the light module 14 to display the first fire power light; when the fire power indication signal indicates that the fire is a medium fire, the control circuit 10 controls the light module 14 to display the second fire power light; when the fire power indication signal indicates that the fire is a low fire, the control circuit 10 controls the light module 14 to display the third fire power light. The first fire power light number, the second fire power light number and the third fire power light number described herein are displayed by presenting light numbers of different colors or by light-emitting elements 142 at different positions.

In step S707, it is determined whether it is abnormal. The control circuit 10 determines whether an abnormal signal is received, where the abnormal signal is, for example, that the gas safety device suction valve is completed and it is determined that there is no furnace flame, the gas safety device suction valve is abnormal and it is determined that there is no furnace flame, or other related ignition abnormalities.

In step S709, an abnormal light signal is displayed. When step S707 is determined to be yes, the control circuit 10 can control the light module 14 to stop displaying the power light signal and control the light module 14 to display the abnormal light signal.

In one embodiment, the control circuit 10 controls the light module 14 to display different abnormal light signals according to the abnormal signals received for different abnormal conditions. The different abnormal light signal display methods include, for example, flashing different light elements 142 in the light module 14A, or flashing different color light signals in the light module 14B.

Next, an example is given to illustrate the use of the gas stove fire power luminous indicator device in the gas stove. Please refer to FIG8A for a schematic diagram of a light module with multiple light-emitting elements displaying a low fire and FIG8B for a schematic diagram of a light module with multiple light-emitting elements displaying a medium fire. As shown in FIG8A, when the gas stove fire power luminous indicator device 1 knows that the fire power of the gas stove is a low fire through the aforementioned detection mechanism, the light-emitting element 142 in the light module 14A displays a light signal that is relatively representative of a low fire. As shown in FIG8B, when the gas stove fire power luminous indicator device 1 knows that the fire power of the gas stove is a medium fire through the aforementioned detection mechanism, the light-emitting element 142 in the light module 14A displays a light signal that is relatively representative of a medium fire. It can be seen from this that the gas stove fire power luminous indicating device 1 can distinguish the fire power of different stoves through the display of different luminous elements 142 .

Please refer to FIG9A for a schematic diagram of a light module that emits light through a light guide to display a medium fire and FIG9B for a schematic diagram of a light module that emits light through a light guide to display a low fire. As shown in FIG9A , when the gas stove power luminous indicator device 1 knows that the fire power of the gas stove is a low fire through the aforementioned detection mechanism, the side light module 146 in the light module 14B displays a light signal that relatively represents a low fire, and presents a color light signal through the uniform light transmission of the light guide plate 145. As shown in FIG9B , when the gas stove power luminous indicator device 1 knows that the power of the gas stove is medium through the aforementioned detection mechanism, the side light module 146 in the light module 14B displays a light signal representing medium, and presents another color light signal through the uniform light transmission of the light guide plate 145. It can be seen that the gas stove power luminous indicator device 1 can distinguish the power of different stoves through different luminous colors.

In one embodiment, the control circuit 10 may be, for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a system on a chip (SOC), or any combination thereof, and may cooperate with other related circuit elements and firmware to implement the above functional flow.
