[0022] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0024] like Figure 1-5As shown, a coaxial timed illuminated knob system for a gas stove includes a panel 1 with at least one panel opening 11. A knob assembly 2 is mounted on the panel opening 11. The knob assembly 2 includes a gas control valve 21, an illuminated panel 22, an encoder 23, a light-transmitting timer knob 24, and a gas stove knob 25. The gas control valve 21 includes a gas control valve fixing part 211 located on the lower side of the panel 1 and a valve stem 212 rotatable relative to the gas control valve 21. The illuminated panel 22 is mounted on the gas control valve fixing part 211, and the upper end of the valve stem 212 passes through the illuminated panel 22 and the panel opening 11 to contact the gas stove. The gas stove knob 25 is connected to the encoder 23, which includes an encoder fixing part 231 and an encoder rotating part 232. The encoder fixing part 231 is mounted on the light-emitting plate 22, and the encoder fixing part 231 and the encoder rotating part 232 are sleeved on the outside of the valve stem 212. The timing knob 24 is connected to the encoder rotating part 232, and the gas stove knob 25 is mounted on the timing knob 24. The panel 1 is equipped with a built-in control module that is connected to the encoder 23 and the light-emitting plate 22 respectively to detect the encoding signal of the encoder 23 and display the corresponding timing time and control the operation of the light-emitting plate 22 according to the encoding signal. During ignition, rotating the gas stove knob 25 of the knob assembly 2 drives the valve stem 212 to rotate, opening the gas control valve 21 and igniting the gas. When setting the timer, rotate the timer knob 24 of the knob assembly 2 to drive the encoder rotating part 232 of the encoder 23 to rotate and send a timer encoding signal to the built-in control module of the display assembly 3 to set the timer. At this time, the control module controls the light-emitting plate 22 in the knob assembly 2 to emit light and controls the display assembly 3 to display the corresponding set timer. After setting the timer, the countdown begins.

[0025] like Figure 2 As shown, a water-blocking ring 4 is provided between the panel 1 and the timer knob 24, which is fitted onto the panel opening 11 to seal the panel opening 11 and prevent liquid from entering through the panel 1 and damaging the knob assembly 2.

[0026] like Figure 3-4 As shown, the timer knob 24 includes a timer knob rotating part 241 that is connected to the encoder rotating part 232 and is light-transmitting, and a timer knob rotating sleeve 242 that is sleeved on the outside of the timer knob rotating part 241, rotates with the timer knob rotating part 241, and cooperates with the water baffle ring 4. The gas stove knob 25 is mounted on the timer knob rotating sleeve 242. When the timer knob 24 is rotated to set the time, the knob rotating sleeve 242 drives the timer knob rotating part 241 to rotate, and the timer knob rotating part 241 drives the encoder rotating part 232 to rotate synchronously, sending a timer encoding signal to the built-in control module.

[0027] like Figure 4As shown, the inner side of the upper opening of the timer knob rotating sleeve 242 is provided with an inwardly extending and surrounding knob rotating sleeve limiting protrusion 2421. The lower end of the inner side of the timer knob rotating sleeve 242 is provided with a knob rotating sleeve groove 2422. The upper end of the outer side of the timer knob rotating part 241 is provided with a knob rotating part limiting groove 2411 that cooperates with the knob rotating sleeve limiting protrusion 2421. The knob rotating sleeve groove 2422 is provided with a limiting clamp 243 that presses against the bottom surface of the timer knob rotating part 241 and locks the timer knob rotating part 241. The limiting clamp 243 locks the light-transmitting timer knob rotating part 241 into the timer rotating sleeve 242 to form an integral unit, which facilitates the assembly of the timer knob 24.

[0028] like Figure 2-4 As shown, the timer knob rotating part 241 is provided with a timer knob groove 2412, and the gas stove knob 25 is set in the timer knob groove 2412, so that the gas stove knob 25 and the timer knob 24 are tightly connected, improving the overall aesthetics.

[0029] like Figure 1-4 As shown, in this case, the panel 1 is equipped with multiple knob assemblies 2. An LED 221 is positioned on the light-emitting plate 22 near the encoder 23 of each knob assembly 2. After detecting the encoded signal, the display component 3 displays the timing time of the corresponding knob assembly 2 and controls the LED 221 positioned near the corresponding knob assembly 2 to operate. When the time is set, the control module controls the LED 221 positioned near the corresponding knob assembly 2 to illuminate as a prompt, thus associating the displayed timing time with the corresponding working burner and avoiding the problem of inconsistent timing displays for different burners.

[0030] like Figure 3-4 As shown, the knob assembly 2 also includes a light-emitting plate mounting base 4, which is disposed on the gas control valve fixing part 211, and the light-emitting plate 22 is disposed on the light-emitting plate mounting base 4. The gas control valve fixing part 211 is provided with a gas control valve connecting post 213, and the light-emitting plate mounting base 4 is fixed on the gas control valve connecting post 213. The light-emitting plate mounting base 4 is fixed on the gas control valve fixing part 211, and the light-emitting plate mounting base 4 can also be used to securely install the light-emitting plate 22 on the lower side of the knob assembly 2.

[0031] like Figure 1 As shown, in this case, panel 1 is equipped with a burner head 5. Inside the burner head 5 is a gas solenoid valve that is connected to the gas control valve 21 and the display component 3, and is used to shut off the gas under the control of the display component 3 after the timer expires. After the control module calculates the timer, it controls the gas solenoid valve of the corresponding burner head to shut off, so that the furnace body stops burning. The burner head 5 is equipped with an ignition needle 6 for ignition and a thermocouple 7 for detecting whether ignition has occurred, which are respectively connected to the display component 3.

[0032] like Figure 5As shown, from left to right on the top side are the built-in control module circuit, the light-emitting board light-emitting lamp driving circuit, and the encoder detection circuit, while the bottom side is the power connection circuit.

[0033] In practical application, the display settings for the corresponding LED on the knob assembly are as follows: when the thermocouple detects a flame, the LED on the corresponding knob assembly lights up, generally set to illuminate within 5 seconds, but the specific setting can be adjusted according to the actual sampling conditions; when the thermocouple detects that the flame has extinguished, the LED on the corresponding knob assembly turns off.

[0034] Regarding the timer setting, after entering normal combustion mode, rotating one of the encoders will cause the corresponding indicator light to flash. The display component will show "00" minutes by default and also begin flashing. During the flashing of the display component, the user can set the timer duration as needed by rotating the encoder to increase or decrease the time. Slow rotation increases or decreases in 1-minute increments, while fast rotation increases or decreases in 10-minute increments. The timer duration is adjustable in a 199-minute cycle, and the minutes are displayed using a 188-digit digital tube. After setting the time, if the encoder is not rotated within 5 seconds, the display component will stop flashing, and the timer function will be activated. Once activated, the time display will show the time in minutes, and the last 60 seconds will be fully lit, simultaneously displaying a countdown.

[0035] Regarding the timer display, it indicates that multiple burners will be timed simultaneously, and the corresponding indicator lights will flash. The display component will show the shortest timer by default. If you need to check the remaining time of the current burner's timer, you must turn the timer knob once to trigger and view the timer of that burner. At this time, the original time setting will not be changed.

[0036] Regarding the timing change, if you need to readjust the timing during the timing process, rotate the encoder. At this time, the corresponding burner timing displayed on the display component will start flashing. Rotate the encoder as described above to adjust.

[0037] Regarding the cancellation of the timer, specifically, if you need to cancel the timer during the timer setting and start-up process, you need to set the timer duration to "0". After 5 seconds, the display component will turn off and exit the timer state, or you can turn off the stove and the timer will automatically turn off after the flame disappears.

[0038] Specifically, when the timer ends, the display switches to a 60-second countdown display when 60 seconds remain. In the last 10 seconds, a 1Hz buzzer on the display indicates the 10-second timer has ended, and the flame automatically extinguishes. The principle is that the control module provides negative feedback current to the thermocouple, reducing its electromotive force and thus closing the solenoid valve connected to the valve body, achieving gas shut-off and flame termination.

[0039] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
