Description

Technical Field

[0001] This utility model relates to the technical field of intelligent gas furnace equipment, specifically to a multi-functional gas furnace knob control system. Background Technology

[0002] In the current field of gas stove control, especially for outdoor cooking equipment, existing technologies and products have revealed a series of significant drawbacks. For example, traditional outdoor gas stoves (such as barbecue grills) have structural design deficiencies, resulting in a simple control panel layout with poor expandability. They often only have a single knob and require too many physical control positions to achieve basic functions. Furthermore, in terms of core function implementation, the existing gas stove's flame adjustment mechanisms generally lack precision. Flame control is typically based on flame size or knob rotation angle, failing to meet users' growing demand for precise temperature control. Particularly noteworthy is the integrated design of existing stoves, which makes subsequent modifications and upgrades extremely inconvenient and costly. Taking common barbecue grill controllers as an example, their operating logic is complex, lacking an intuitive and convenient human-computer interaction method, making it difficult for users to accurately control key cooking parameters (such as temperature and time). These design flaws and high modification costs, especially the technical difficulties and additional expenses involved in upgrading or modifying existing equipment, severely restrict the performance improvement and market penetration of products in this field. There is an urgent need to develop a structurally innovative, easily implemented, and cost-effective technical solution to break through the current situation. Utility Model Content

[0021] Example 1

[0022] A multi-functional gas stove knob control system, basically as follows: Figure 1 , Figure 2 As shown, it includes:

[0023] The main circuit control board 8 integrates a microprocessor and multiple drive circuit interfaces; in this embodiment, a conventional microcontroller controller is used, such as the STEM32 series, 51 series, or ESP32 series. The main circuit control board also includes a first communication module, which includes a WiFi module and / or a Bluetooth module.

[0024] The knob controller 6, in this embodiment, is connected to the drive circuit interface via a main wiring harness and is detachably electrically connected to the main circuit control board 8. The knob controller 6 includes an internal circuit control module, a rotation sensor, a push switch, a damping device, a display screen, and an illuminated base ring. The rotation sensor (encoder) and push switch are used to capture the rotation angle and confirm the operation command, respectively. The damping device provides rotational resistance feedback. The damping device uses conventional damping materials and structures, such as a combination of a silicone damping ring and a spring, to provide moderate resistance while ensuring smooth rotation, giving the user a clear operating feel. The display screen and illuminated base ring are used to display parameters and fire status, respectively. The display screen uses a high-definition LCD screen, and the screen display mode is set to yellow text on a black background or black text on a white background to improve display clarity and readability, making it convenient for users to clearly read information in different environments. The internal circuit control module integrates a microprocessor, a display screen drive circuit, and a knob sensor (encoder) drive circuit. When the main circuit control board 8 and the knob controller 6 are connected by a wire, their positions relative to the gas furnace device are fixed. In other embodiments, the internal circuit control module is equipped with a battery and communicates with the first communication module of the main circuit control board 8 via a second communication module. It controls the display screen content and the device's preset program operations according to a pre-programmed sequence, thereby controlling the entire gas furnace device. The gas furnace device's position is not fixed; it can be moved within the communication range of the first and second communication modules or placed in a fixed position, making it more convenient for users. The second communication module includes a WiFi module and / or a Bluetooth module. The main circuit control board 8 and the knob controller 6 can be connected via wired or wireless connections, or both.

[0025] The knob controller 6 has one output port (integrated socket), the number of pins of which is determined according to the overall functional requirements, for connecting the main wiring harness; it also has one power input port, which can be designed to be integrated with the output port, with the power input terminal branched off from the main wiring harness, and its input voltage is generally set to 12V. The base is designed with three food probe 7 interfaces, allowing users to connect food probes 7 to obtain information such as the internal temperature of food.

[0026] The functional module group, including igniter 10, gas control valve 9, furnace temperature probe 1, ionization probe 3, gas cylinder weighing gauge 5, external lighting strip, ambient light, and illumination light 2, is directly connected to the drive circuit interface of the main circuit control board 8 via standardized connectors. The main circuit control board 8 integrates a microprocessor, temperature sensor interface, and drive circuits for the gas control valve 9, igniter 10, ionization probe 3, and gas cylinder weighing gauge 5.

[0027] Igniter 10: Controls the ignition of the burner head. The current power supply voltage is 1.5 volts, and the output is greater than 20 kV. It is directly connected to the main circuit control board 8 through the wiring harness connector. Igniter 10 is connected to the ignition needle 4 to achieve automatic ignition.

[0028] Gas control valve 9: Divided into solenoid valve and proportional valve, used to control the gas flame intensity and its on / off state. It is directly connected to the main circuit board via a wiring harness connector, and the flame adjustment command is sent by the knob controller 6.

[0029] Furnace temperature probe 1: It adopts a two-pin interface and is electrically connected to the main circuit control board 8. The model is PT1000B, 0℃=1000K+1%. Its main function is to sense the furnace front temperature and provide signal basis for the control system to make decisions and give instructions. It transmits signals through a two-wire interface.

[0030] Ion probe 3: It is electrically connected to the main circuit board and is used to sense whether the flame is extinguished or burning. It transmits signals through a 2-wire interface.

[0031] Gas cylinder weighing scale 5: It is directly connected to the main circuit control board 8 via a signal line and is used to weigh gas cylinders. It adopts a three-pin connector and the transmission mode is serial port transmission (IIC). The progress bar can be displayed independently on the display screen of the knob controller 6.

[0032] The external light strip is synchronized with the color of the luminous base ring of the knob controller 6. The external light strip, ambient light, and lighting lamp 2 are electrically connected to the drive circuit interface of the main circuit control board 8 through the main wiring harness.

[0033] The functional module group also includes multiple food probes 7. The base of the knob controller 6 is equipped with a food probe 7 interface, and the food probes 7 are electrically connected to this interface. The food probe 7 interface of the knob controller 6 is a 3.5mm audio jack. The food probes 7 are used to detect food temperature and are of model NTC (R25℃=100K±1% B25 / 50=3950K±1%). In this embodiment, the base of the knob controller 6 is designed with three food probe 7 interfaces, facilitating user connection of the food probes 7 to obtain information such as the internal temperature of the food.

[0034] Working Principle: Upon power-on, the display screen illuminates, and the controller base light and ambient light or light strip simultaneously illuminate. If not operated, the display screen turns off after one minute, and the knob controls the illuminated base ring and ambient light to enter a breathing light sleep mode. After setting relevant function parameters (selecting firepower, time, etc.) via the knob controller 6, the firepower can be adjusted at any time during operation, specifically controlled by the solenoid valve's airflow. If the flame goes out during operation (detected by the ion probe 3, which sends a signal to the controller), it will automatically reignite (lasting 10 seconds, 3 times). If ignition fails, a fault will be displayed on the screen. When the gas cylinder weighing gauge 5 is empty, the entire display flashes red and an alarm sounds. The color of the illuminated base ring and ambient light changes according to the temperature sensed by the furnace temperature probe 1; different colors indicate the flame's high, low, or medium fire status after ignition. The flame is blue when not ignited, turns orange when ignited, orange when ignited, and red when ignited. The color changes gradually from orange to red.

[0035] Compared to existing technologies, the key advantages of this solution are:

[0036] Performance Enhancement: Significantly improves ease of operation and control precision. Users can quickly and accurately select cooking modes and parameters, enhancing the reliability and stability of the equipment in practical applications. For example, precise temperature control ensures consistent cooking results and reduces the probability of food cooking failure.

[0037] Cost optimization: By adopting a modular, pluggable, standardized interface design and a highly integrated knob controller structure, raw material costs are reduced. At the same time, the simple structural design and standardized circuit modules simplify the manufacturing process and effectively save production costs.

[0038] Functional Expansion: The unique luminous base ring and light strip design, along with rich menu modes, meet the diverse needs of users in different cooking scenarios. The new intelligent control function brings users a better and more convenient user experience, significantly expanding the product's application areas, such as home kitchens and small catering establishments.
