Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and in particular to a gas stove with a flame level indicator. Background Technology

[0002] The most common type of gas stove on the market is the purely mechanical type. Its flame control relies entirely on the physical linkage between the mechanical valve and the knob. A significant drawback of this type of gas stove is that users cannot accurately determine the current flame level. The markings on the knob are usually just illustrative icons, and users can only roughly judge by bending over and looking at the size of the flame under the pot, which becomes especially difficult when large pots are placed on it. Secondly, at the moment of ignition, users also need to look down to confirm successful ignition. This "blind operation" mode not only reduces the precision and convenience of cooking but also leads to a poor user experience.

[0003] Of course, many gas stoves nowadays are equipped with flame failure devices. These devices shut off the gas valve in the event of an accidental flameout (such as being blown out by wind or spilled soup). However, these safety devices typically operate silently, without providing any audible or visual alerts after the gas is cut off. Users often only realize the flame is out after a period of time when the food hasn't been heated. This not only interrupts the cooking process but also leaves the user unable to monitor the stove's real-time operating status (whether it has ignited successfully or is burning).

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a gas stove that can visualize the firepower and working status.

[0008] The stove body includes a control panel;

[0009] A gas supply system is installed in the stove body and includes a burner head, at least one gas pipeline connected to the burner head, and a valve body installed on the gas pipeline for controlling its on / off state.

[0010] The user control assembly includes a knob disposed on the panel and kinetically connected to the valve body;

[0020] In order to further solve the technical problems to be solved by this utility model, the flame sensing needle in the gas stove with flame indication provided by this utility model is a thermocouple type or an ion sensing type sensor.

[0021] To further address the technical problem to be solved by this utility model, the main controller of the gas stove with flame indication provided by this utility model is further configured to determine an accidental flameout state when the received rotation status signal indicates that the valve body should be in the conducting state, and the received flame status signal indicates that there is no flame; in response to the determination of an accidental flameout state, the main controller drives the flame indication unit to provide a warning in a preset warning mode.

[0022] To further address the technical problems addressed by this utility model, this utility model provides a gas stove with a flame indicator, wherein the valve body and the main controller are electrically connected.

The combined result is then fed back in real-time and visually through a multi-mode firepower indicator unit. This design offers three significant advantages: 1) Intuitive and convenient: Users can accurately understand the current firepower level simply by observing the color or brightness of the light at the knob, eliminating the need to bend down to check the flame, greatly improving cooking control precision and ease of operation. 2) Intelligent safety: It can intelligently distinguish between "actively turning off the flame" and "accidentally extinguishing the flame," providing timely audible and visual warnings or even automatically cutting off the gas supply in the latter case. Compared to traditional silent flameout protection, this represents a qualitative leap in safety. 3) Excellent human-computer interaction: Combining passive mechanical operation with active electronic feedback makes the gas stove's operating status transparent and knowable, significantly improving the user experience.

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:

[0030] Figure 1 This is a three-dimensional structural schematic diagram of the present invention;

[0031] Figure 2 This is an exploded view of the present invention;

[0032] Figure 3 This is a structural block diagram of the present invention. Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please see Figures 1 to 3 This embodiment provides a gas stove with a firepower indicator, which aims to solve the problem in the prior art that users cannot intuitively understand the firepower and working status.

[0035] like Figure 1 and Figure 2 As shown, the gas stove includes a stove body with a panel 1 on top. A burner 2 is mounted on the panel 1 and is used to generate a flame. Inside the stove body, a gas supply system is provided, which includes a gas pipeline connected to the burner 2 and a valve body 21 installed on the pipeline. The valve body 21 is used to control the gas flow rate to the burner 2.

[0036] A knob 3 is provided on the panel 1. The knob 3 is mechanically connected to the valve body 21 through the valve stem. By rotating the knob 3, the user can directly change the opening of the valve body 21, thereby achieving preliminary mechanical adjustment of the flame size.

[0037] To achieve the core function of this utility model, the gas stove also includes a flame sensing and indication system. Please refer to... Figure 3 The system includes:

[0038] A main controller 7, in this embodiment, is preferably a printed circuit board (PCB) integrating a microprocessor (MCU) or a single-chip microcomputer, which has a preset control program built in.

[0039] A rotation detection unit 4 is linked to the knob 3. In a preferred embodiment, the rotation detection unit 4 is a rotary encoder, which is coaxially arranged with the rotating shaft of the knob 3. When the user rotates the knob 3, the rotary encoder will detect its rotation angle or gear in real time and generate a corresponding electrical signal (i.e., a rotation status signal) and send it to the main controller 7.

[0040] A flame detection unit 5 is disposed beside the burner head 2, and its sensing end is designed to effectively contact or approach the flame. In this embodiment, the flame detection unit 5 is a flame sensing needle, such as a thermocouple sensor utilizing the thermoelectric effect, or an ion sensing sensor utilizing the flame ionization characteristics. It can detect in real time whether a flame exists on the burner head 2 and the intensity of the flame (manifested as temperature or ion current magnitude), and convert the detection result into an electrical signal (i.e., a flame status signal) and send it to the main controller 7.

[0041] A fire indicator unit 6 is positioned in a location easily observed by the user. Preferably, the fire indicator unit 6 is integrated inside the knob 3, or is a ring-shaped light strip surrounding the knob 3. In this embodiment, the fire indicator unit 6 is one or a group of multi-color LEDs. It receives drive signals from the main controller 7 and provides information to the user by changing its color, brightness, or flashing pattern. Of course, the fire indicator unit 6 can also be an audible and visual alarm.

[0042] In addition, to achieve automatic ignition, the gas stove also includes an ignition controller 8 linked to the knob 3 and an ignition needle 9 located next to the burner head 2.

[0043] The working process and principle of this utility model are described in detail below:

[0044] 1) Ignition and normal firepower adjustment process

[0045] The user presses knob 3 from the off position and rotates it to the ignition position. This action, on the one hand, mechanically opens valve body 21 to release gas, and on the other hand, triggers ignition controller 8 to drive ignition needle 9 to generate an electric spark, igniting the gas. After the flame is ignited, flame detection unit 5 (e.g., thermocouple) is heated, quickly generating a "flame normal" signal and sending it to main controller 7. Main controller 7 confirms successful ignition. The user continues to rotate knob 3 to adjust the flame intensity. Rotation detection unit 4 (rotary encoder) sends the real-time rotation angle information of knob 3 to main controller 7. Main controller 7 has a preset correspondence between angle and flame intensity level (e.g., 15°-40° for low flame, 41°-70° for medium flame, 71°-90° for high flame). Based on the received angle information, main controller 7 determines the flame intensity level set by the user and drives flame indicator unit 6 (multi-color LED light) to display the corresponding color. For example, at low flame, the light ring around knob 3 displays blue; at medium flame, it displays yellow; and at high flame, it displays red. Therefore, users do not need to bend over to observe the flame; they can clearly know the current heat level simply by looking at the color of the light at knob 3, thus achieving precise control of the cooking process.

[0046] 2) Safety monitoring and warning process for accidental engine shutdown

[0047] Suppose that the gas stove is burning normally (e.g., medium flame, yellow indicator light) when the flame is accidentally extinguished due to wind or spilled soup. At this time, the knob 3 remains in the same position, and the rotation detection unit 4 continues to send a "medium flame" signal to the main controller 7. Simultaneously, the flame detection unit 5 cools rapidly due to the flame disappearing, and its signal to the main controller 7 changes to "no flame." The main controller 7 receives these two contradictory signals at the same time and immediately determines that an "accidental flameout" has occurred. To ensure safety, the main controller 7 immediately executes a preset alarm procedure: First, it drives the flame indicator unit 6 to provide a warning in a preset mode, such as flashing a red light at a high frequency on the indicator light, and optionally triggers a buzzer to emit a "beep" alarm sound, alerting the user in the most conspicuous way. Simultaneously with or after a slight delay (e.g., 1-3 seconds to prevent misjudgment), the main controller 7 can further send a command via electrical connection to an electrically controlled valve body 21 or an additional solenoid valve, forcing it to close, thereby completely cutting off the gas supply and preventing gas leakage.

[0048] 3) Normal procedure for automatic shutdown

[0049] When the user finishes cooking, they manually rotate knob 3 to the off position. The rotation detection unit 4 sends a "off" signal to the main controller 7. Simultaneously, valve body 21 is mechanically closed, the flame is extinguished, and flame detection unit 5 also sends a "no flame" signal to the main controller 7. The main controller 7 receives both the "knob off" and "no flame" signals and determines that it is a normal automatic shut-off. At this time, the main controller 7 will extinguish the flame indicator unit 6, and the stove will enter standby mode without generating any warnings.

[0050] In summary, this invention, by adding a main controller, a rotation detection unit, a flame detection unit, and a flame indicator unit, and organically combining them, not only achieves intuitive and visual prompts of flame intensity, but more importantly, it can intelligently distinguish between the user's operational intention (active flameout) and dangerous accidental states (accidental flameout), and provide distinctly different responses. This greatly improves the convenience, accuracy, and safety of using the gas stove, bringing users a superior user experience.

[0051] Those skilled in the art should understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
