Description

Technical Field

[0001] This utility model relates to the field of oven technology, and more specifically, to an oven structure. Background Technology

[0002] Currently, outdoor grills typically employ a suspended design to meet the design requirements for flame observation, supporting the grill pan on the grill so that users can directly see whether the flame is present during use. However, in related technologies, grills with a suspended design are prone to heat loss in outdoor scenarios. In windy conditions, some heat is blown away by the wind, and even in windless conditions, heat will flow outward through the suspended part, resulting in low thermal efficiency. Utility Model Content

[0003] This invention aims to at least solve the technical problem of low thermal efficiency of existing outdoor ovens in the prior art or related technologies.

[0004] In view of this, an embodiment of the present invention provides an oven structure.

[0005] To achieve the above objectives, embodiments of this utility model provide an oven structure, comprising: an oven shell with a cooking opening inside; a combustion chamber disposed within the oven shell, containing a burner; a cooking tray movably connected to the oven shell, wherein, when the cooking tray is assembled to the oven shell, at least a portion of the cooking tray is recessed below the plane of the cooking opening, and the projection of the cooking tray onto the plane of the cooking opening is within the cooking opening; a flame detection element, at least a portion of which is disposed within the combustion chamber, with the flame detection element positioned opposite to the burner; and an indicator electrically connected to the flame detection element, disposed outside the oven shell.

[0006] The oven structure proposed in this utility model includes an oven shell, a combustion chamber, a cooking tray, and flame detection and indicator components. Under the combined action of the flame detection and indicator components, the combustion status can be monitored in real time, preventing gas leakage caused by flame extinguishing. Specifically, the oven shell serves as the external frame of the entire structure, providing support and protection. The oven shell contains a cooking opening and a combustion chamber, providing the necessary space for combustion and cooking. The cooking opening is used to place food and is the opening between the oven and the outside environment. The position of this opening needs to be precisely designed to ensure even heating of the food.

[0007] The combustion chamber is where the gas is burned, and it contains a burner. The design of the combustion chamber must ensure thorough mixing of the gas and air to achieve optimal combustion. The burner is responsible for igniting and burning the gas, converting chemical energy into heat energy. Located within the combustion chamber, the burner's proper arrangement ensures even heat distribution and improves thermal efficiency.

[0008] It is important to emphasize that the cooking plate in this solution is an embedded assembly, which can effectively improve thermal efficiency compared to traditional suspended baking pans. The cooking plate is used to place food and is directly heated. At least part of the cooking plate is sunken into the plane where the cooking opening is located, that is, part of the structure in the cooking plate is sunken, which reduces the leakage of heat from the flame and ensures that it maintains good contact with the heat generated by combustion during use, thereby improving thermal efficiency.

[0009] Flame detectors are used to monitor whether the burner flame is functioning properly, primarily through thermocouples or similar sensors. Located within the combustion chamber, opposite the burner, the flame detector is designed to monitor the flame status in real time, preventing leaks caused by continued gas supply after the flame has extinguished. The placement of the flame detector ensures it can accurately sense the presence or extinguishment of the flame and provide timely feedback.

[0010] In some technical solutions, optionally, a support plate is also included, located on the side of the combustion chamber facing the cooking opening, and the cooking plate is placed on the support plate; wherein the support plate is a hollow structure.

[0011] In this technical solution, a support plate is provided and designed as a hollow structure. The support plate is located on the side of the combustion chamber facing the cooking opening, and its main function is to support the cooking plate, allowing it to be stably placed at an appropriate height and position. It can be understood that the support plate provides a sturdy and stable platform, enabling the cooking plate to be suspended or placed smoothly within the combustion chamber, ensuring even heat distribution and preventing the cooking plate from tilting or moving, thereby maintaining thermal efficiency.

[0012] Because the support plate is a hollow structure, the heat generated by the burner can be directly applied to the cooking plate through the hollow structure, improving thermal efficiency. At the same time, the hollow design helps the heat circulate near the support plate, potentially improving the thermal efficiency of the cooking area.

[0013] In some technical solutions, the flame detection element may optionally include: a detection terminal located in the combustion chamber and positioned opposite to the burner; and a detection cable, one end of which is connected to the detection terminal and the other end of which is electrically connected to an indicator.

[0014] In this technical solution, the flame detection device includes a terminal structure and a cable, namely, a connected detection terminal and a detection cable. The detection terminal is located in the combustion chamber and is positioned opposite to the burner. Its main function is to monitor the flame status at the burner in real time. It typically detects the presence of a flame by sensing the thermoelectric potential generated by the flame through principles such as thermocouples.

[0015] The detection cable connects the detection terminal and the indicator. One end is connected to the detection terminal, and the other end is electrically connected to the indicator. The signal from the detection terminal is transmitted to the indicator, usually through changes in current or thermoelectric potential.

[0016] The indicator receives flame status signals via a detection cable and informs the user whether the flame is functioning properly through visual feedback (such as LED indicator lights). The indicator is typically located on the exterior of the oven for easy viewing. The feedback from the indicator allows the user to visually observe the flame's working status. For example, the indicator light illuminates when the flame is normal and turns off when the flame is extinguished, thus reminding the user to check the flame and gas supply to prevent gas leaks.

[0017] In some technical solutions, optionally, a control box is also included, which is located on one side of the oven shell. The control box contains a circuit board, the other end of the detection cable is electrically connected to the circuit board, and the indicator is electrically connected to the circuit board.

[0018] In this technical solution, the control box is the core control unit of the entire flame detection and feedback system. Located on one side of the oven shell, the control box contains a circuit board responsible for managing signal transmission, processing, and feedback. The control box receives flame signals from the detection cable via the circuit board and transmits the signals to the indicator, thereby achieving monitoring and feedback of the flame status.

[0019] In some technical solutions, the oven shell may optionally include a movably connected oven body and a cover, with a cooking opening on one side of the oven body; wherein, a control panel is provided on the front side of the oven body, and indicators are located within the control panel.

[0020] In this technical solution, the oven shell mainly consists of a movable oven body and a lid, which together form a complete oven outer shell. Hinges or other movable connection methods are typically used to allow the lid to be easily opened and closed, facilitating not only operation but also cleaning and maintenance.

[0021] The flexible lid design allows users to easily open it to place or turn food during use, and also enables quick cleaning of the interior after use. The lid's airtight seal ensures heat retention and a stable internal oven temperature.

[0022] The cooking opening of the oven is located on one side of the oven body, serving as a passage for putting in and taking out food, which facilitates user operation, especially under high-temperature conditions. The location of the cooking opening allows users to safely and conveniently put in and take out food, while ensuring maximum thermal efficiency. Other functional parts of the oven (such as the burner and flame detection device) are all concentrated near the cooking opening, ensuring that heat is applied directly to the food.

[0023] The control panel is positioned at the front of the oven, allowing users to easily see and operate all its functions. The control panel typically includes controls for temperature adjustment, time setting, and flame monitoring. This placement makes all control buttons easily accessible and the operation more intuitive. Through the control panel, users can adjust oven operating parameters (such as temperature and time) in real time, enhancing ease of use and flexibility.

[0024] In some technical solutions, optionally, the control panel is provided with at least one mounting hole, and the indicator specifically includes: a lampshade structure, which is detachably connected to the control panel, and the projection of the lampshade structure on the control panel covers the mounting hole; and a light-emitting element, which is detachably connected to the lampshade structure and is electrically connected to the circuit board.

[0025] In this technical solution, mounting holes are provided on the control panel to facilitate the installation of the indicator. Specifically, the indicator includes a detachably connected lampshade structure and a light-emitting element. The lampshade structure protects the light-emitting element and is detachably connected to the control panel, allowing users to easily replace or maintain the light-emitting element. The design of the lampshade structure ensures the safety of the light-emitting element, while its detachability increases the ease of oven maintenance. The shape and material design of the lampshade also help diffuse the light, making the indicator light softer and more uniform, avoiding direct glare that could irritate the user's eyesight.

[0026] The control panel has at least one mounting hole, and the lampshade structure is detachably connected to these holes, ensuring the lampshade is securely fixed to the control panel. The projection of the lampshade structure covers the mounting hole, ensuring precise installation and a tight fit with the control panel design. This design not only guarantees the lampshade's stability but also optimizes the control panel's appearance, giving the oven a more modern look. The light-emitting element is installed inside the lampshade structure and connected to the circuit board via electrical connections. The lampshade structure effectively protects the light-emitting element and ensures that the light is evenly distributed. The light-emitting element is located within the lampshade structure, and the shape and size of the lampshade ensure that the element is clearly visible from the outside, and that light propagation is not obstructed or distorted by the lampshade.

[0027] The lampshade structure is detachably connected to the control panel, and its projection on the control panel covers the mounting holes, ensuring a stable installation and compact structure. The well-designed mounting holes allow for accurate alignment and secure fixation of the lampshade to the control panel. This detachable connection simplifies assembly, disassembly, and maintenance. The mounting holes on the control panel guarantee precise lampshade placement, preventing loosening or misalignment between the lampshade and the control panel, ensuring good visual appeal and structural stability.

[0028] In some technical solutions, optionally, a seal is also included, disposed between the lampshade structure and the control panel, the shape of which is adapted to the shape of the mounting hole.

[0029] In this technical solution, a seal is placed between the lampshade structure and the control panel to ensure a tight seal between the two. The shape of the seal is adapted to the mounting holes on the control panel, enabling it to effectively prevent air, moisture, or dust from entering the oven, while also preventing the leakage of fumes or heat.

[0030] This sealing design helps maintain a more stable environment inside the oven, reduces the entry of external contaminants into the control panel area, and prevents excessive temperature or moisture from entering the circuit board, thereby improving the oven's safety and durability.

[0031] In some technical solutions, optionally, a floor support is also included, located on the side of the oven body away from the cover; wherein the control box is located on the side of the floor support facing the oven shell.

[0032] In this technical solution, by setting up a floor support and placing it on the side of the oven body away from the cover, the oven can be supported and a stable foundation can be provided. By installing the floor support on one side of the oven body, the weight of the entire oven is effectively distributed, thereby enhancing the stability and safety of the equipment. In particular, the support can provide additional support when moving or adjusting the position of the oven.

[0033] In some technical solutions, optionally, a control knob is also included, located on the control panel, the control knob being used to control at least one burner; wherein an indicator is correspondingly located on the control panel to the control knob.

[0034] In this technical solution, the combination of control knobs and indicators increases user convenience and further enhances the oven's safety and functionality. The control knobs are located on the control panel, allowing users to adjust the operating status of at least one burner (such as ignition, adjusting heat intensity, or turning off the burner) by rotating them. The knob design enables users to operate the oven intuitively and easily.

[0035] By using the control knob, users can quickly adjust the burner's heat output, achieving precise temperature control and ensuring the oven can effectively adapt to different cooking needs. Furthermore, the control knob not only controls the burner's operation but also indirectly links to the flame detector. When the control knob adjusts the heat or shuts off the burner, the flame detector immediately reports whether the flame has extinguished, preventing potential hazards caused by continued gas flow after the flame is extinguished. This interconnected design ensures that no gas leaks or other safety hazards occur after the burner is shut off, increasing the oven's safety.

[0036] The indicator and control knob are located on the control panel to display the flame's operating status. Changes in the indicator visually indicate whether the burner is functioning correctly. The indicator provides immediate feedback: a lit indicator means the flame is working properly, and an unlit indicator means the flame is extinguished. This feedback mechanism effectively prevents gas leaks and helps users promptly identify and resolve problems.

[0037] When the control knob adjusts the burner's heat or turns it off, the indicator shows the flame status, alerting the user whether the flame has gone out. This function significantly improves the oven's safety. Users can promptly detect whether the oven is operating normally; if the indicator light goes out, users can take immediate action to prevent gas leaks caused by a extinguished flame.

[0038] In some technical solutions, optionally, a heat insulation element is also included, disposed within the combustion chamber, and the heat insulation element is disposed around the burner and flame detection element which are disposed opposite to each other.

[0039] In this technical solution, by installing a heat insulation component inside the combustion chamber, specifically surrounding the burner and flame detection component that are positioned opposite each other, the burner and flame detection component can be isolated. This avoids the high temperature directly affecting the flame detection component, thus preventing it from affecting its detection accuracy and stability. On the other hand, it ensures that the flame detection component can accurately detect whether there is a flame in the burner.

[0053] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 9 Some embodiments according to the present invention are described.

[0056] like Figure 1 and Figure 2As shown, this embodiment provides an oven structure 100, including an oven shell 102, a combustion chamber 104, a cooking tray 106, and a flame detector and indicator 110. With the combined action of the flame detector 108 and indicator 110, the combustion status can be monitored in real time, preventing gas leakage caused by flame extinguishing. Specifically, the oven shell 102 is the outer frame of the entire structure, providing support and protection. The oven shell 102 contains a cooking opening 1022 and a combustion chamber 104, providing the necessary space for combustion and cooking. The cooking opening 1022 is for placing food and is the opening between the oven and the outside environment. The position of this opening needs to be precisely designed to ensure even heating of the food.

[0057] The combustion chamber 104 is where the gas is burned, and it contains a burner 1042. The design of the combustion chamber 104 must ensure that the gas and air are fully mixed to achieve optimal combustion. The burner 1042 is responsible for igniting and burning the gas, converting chemical energy into heat energy. The burner 1042 is located inside the combustion chamber 104, and its proper arrangement ensures uniform heat distribution and improves thermal efficiency.

[0058] It should be emphasized that the cooking plate 106 in this solution is an embedded assembly, which can effectively improve thermal efficiency compared to the traditional suspended baking pan. The cooking plate 106 is used to place food and be directly heated. At least part of the cooking plate 106 is sunken in the plane where the cooking opening 1022 is located, that is, part of the structure in the cooking plate 106 is sunken, which reduces the leakage of heat from the flame and ensures that it maintains good contact with the heat generated by combustion during use, thereby improving thermal efficiency.

[0059] The flame detector 108 is used to monitor whether the flame of the burner 1042 is operating normally, mainly through a thermocouple or similar sensor. The flame detector 108 is located inside the combustion chamber 104, opposite to the burner 1042. The design of the flame detector 108 enables real-time monitoring of the flame status, preventing leaks caused by continued gas supply after the flame has extinguished. The placement of the flame detector 108 ensures that it can accurately sense the presence or extinguishment of the flame and provide timely feedback.

[0060] The indicator 110 is electrically connected to the flame detector 108 and is used to provide feedback to the user on whether the flame is functioning normally. The indicator 110 is typically an LED indicator or display, located on the exterior of the oven housing 102 for easy observation by the user. The design of the indicator 110 allows the user to visually see whether the flame is normal, enhancing the user's safety awareness and user experience. The indicator light illuminates when the flame is normal and turns off when the flame is extinguished, ensuring that the user can take timely action.

[0061] The cooking tray 106 is connected to the oven shell 102 via a movable structure, and its position can be adjusted as needed, especially when it is lowered into the plane of the cooking opening 1022 during assembly. Lowering the cooking tray 106 into the plane of the cooking opening 1022 ensures good contact between it and the heat generated by the burner 1042, improving thermal efficiency.

[0062] It should be added that the flame detection element 108 needs to be set opposite to the burner 1042 to ensure that it can sense the flame status at the burner 1042. The flame detection element 108 should be located in the combustion chamber 104, close to the burner 1042, so as to accurately detect whether the flame is working properly.

[0063] The flame detector 108 is connected to the indicator 110 via a circuit, transmitting flame status information to the indicator 110. The indicator 110 alerts the user via feedback light or display. The indicator 110 is located outside the oven housing 102 for easy observation by the user. The circuitry and wiring harness must ensure stable and accurate signal transmission between the flame detector 108 and the indicator 110.

[0064] The overall structural design takes into account thermal efficiency, safety, and user experience, ensuring that the gas oven burns efficiently while avoiding safety hazards caused by flameout. The movable design of the cooking plate 106 improves heat utilization, while the flame detection and indicator 110 enhances safety and ease of operation.

[0065] Furthermore, the flame detection component 108 includes: a thermocouple sensor, a resistance temperature detector (RTD) sensor, and a thermistor sensor.

[0066] In some embodiments, a support plate 112 is optionally provided and configured as a hollow structure. The support plate 112 is located on the side of the combustion chamber 104 facing the cooking opening 1022, and its main function is to support the cooking plate 106, allowing it to be stably placed at an appropriate height and position. It is understood that the support plate 112 provides a robust and stable platform, enabling the cooking plate 106 to be smoothly suspended or placed within the combustion chamber 104, ensuring uniform heat distribution and preventing the cooking plate 106 from tilting or moving, thereby maintaining thermal efficiency.

[0067] Because the support plate 112 is a hollow structure, the heat generated by the burner 1042 can be directly applied to the cooking plate 106 through the hollow structure, thereby improving thermal efficiency. At the same time, the hollow design helps the heat to circulate near the support plate 112, which may improve the thermal efficiency of the cooking area.

[0068] It should be added that the support plate 112 is located on the side of the combustion chamber 104 facing the cooking opening 1022 and is fixedly connected to the side wall of the combustion chamber 104. The design of the support plate 112 needs to ensure that it can firmly support the cooking plate 106 without affecting the heat flow or heat distribution of the combustion chamber 104. The cooking plate 106 is placed on the support plate 112, typically using a groove, snap-fit, or nesting design to ensure that the cooking plate 106 can be stably fixed on the support plate 112 without sliding or tilting.

[0069] The lowering of the support plate 112 allows the cooking plate 106 to be located inside the cooking opening 1022 and aligned with the plane of the cooking opening 1022. This ensures that the cooking plate 106 can make full use of the heat generated by the burner 1042 when the oven is in use, thus achieving efficient cooking.

[0070] The hollow design of the support plate 112 allows for the flow of hot air, which can be enhanced through optimized vent or channel design. The hollow structure helps to evenly transfer heat within the combustion chamber 104 to every corner of the cooking plate 106.

[0071] Furthermore, the hollow portion of the support plate 112 can be connected to the airflow channel of the combustion chamber 104, allowing hot air to circulate in the cavity of the support plate 112, thereby further improving thermal efficiency.

[0072] In some embodiments, the flame detection element 108 may optionally include a terminal structure and a cable, namely a connected detection terminal 1082 and a detection cable 1084. The detection terminal 1082 is located in the combustion chamber 104 and is arranged opposite to the burner 1042. Its main function is to monitor the flame state at the burner 1042 in real time. It usually detects the presence of a flame by sensing the thermoelectric potential generated by the flame through the principle of thermocouples, etc.

[0073] The detection cable 1084 connects the detection terminal 1082 and the indicator 110. One end is connected to the detection terminal 1082 and the other end is electrically connected to the indicator 110. The signal from the detection terminal 1082 is transmitted to the indicator 110, usually through a change in current or a change in thermoelectric potential.

[0074] Indicator 110 receives flame status signals via detection cable 1084 and informs the user whether the flame is normal through visual feedback (such as an LED indicator). Indicator 110 is typically located on the exterior of the oven for easy viewing by the user. The feedback from indicator 110 allows the user to visually observe the flame's operating status. For example, the indicator light illuminates when the flame is normal and turns off when the flame is extinguished, thus reminding the user to check the flame and gas supply to prevent gas leaks.

[0075] Furthermore, the relative arrangement between the detection terminal 1082 and the burner 1042 needs to ensure that it can accurately sense the flame state near the burner 1042. The detection terminal 1082 needs to maintain an appropriate distance from the burner 1042 to ensure that it can sense the thermal effect of the flame, but is not affected by the external environment of the burner 1042. A reasonable relative arrangement ensures that the flame can be detected quickly when it is extinguished, triggering an alarm.

[0076] The output signal from the detection terminal 1082 is transmitted to the indicator 110 via the detection cable 1084. One end of the detection cable 1084 is electrically connected to the detection terminal 1082, and the other end is electrically connected to the indicator 110, forming a signal transmission circuit. The other end of the detection cable 1084 is connected to the indicator 110, transmitting the flame status signal to the indicator 110. Upon receiving the signal, the indicator 110 provides visual feedback (such as an LED light) to indicate the flame status to the user.

[0077] The indicator 110 is usually located outside the oven for easy viewing by the user. Its connection with the detection cable 1084 should be reliable and stable to ensure that the signal transmission is not interfered with and that the feedback information is timely and accurate.

[0078] In some embodiments, optionally, the control box 114 is the core control unit of the entire flame detection and feedback system, located on one side of the oven housing 102, such as... Figure 1 and Figure 5 As shown, the control box 114 contains a circuit board 1142, which is responsible for managing the transmission, processing, and feedback of signals. The control box 114 receives the flame signal from the detection cable 1084 through the circuit board 1142 and transmits the signal to the indicator 110, thereby realizing the monitoring and feedback of the flame status.

[0079] The control box 114 integrates multiple components (such as detection cable 1084 and indicator 110) into one unit. Through centralized management and control, it reduces system complexity and redundant connections, thereby improving system reliability and stability. The circuit board 1142 inside the control box 114 is responsible for signal processing and logic control, ensuring timely and accurate signal transmission.

[0080] Circuit board 1142 is the core component within control box 114, responsible for processing the flame status signal received from detection cable 1084. After processing the signal, it drives indicator 110 (such as LED indicator) to provide corresponding feedback. Circuit board 1142 may also include protection circuitry, signal amplification, and regulation functions to ensure the flame monitoring system operates normally under various conditions.

[0081] The function of circuit board 1142 is to convert the flame detection signal into visual feedback that is easy for users to understand (such as the on / off state of an indicator light). This feedback can promptly and intuitively inform the user of the flame status, preventing gas leaks and safety issues caused by flame extinguishing. The efficient processing capability and stability of circuit board 1142 are crucial to the reliability of the system.

[0082] One end of the detection cable 1084 is connected to the flame detection terminal 1082, and the other end is electrically connected to the circuit board 1142 to ensure the transmission of the flame detection signal. The circuit board 1142 processes the received signal and feeds it back to the user via the indicator 110, ensuring that the flame status signal is accurately and promptly transmitted to the circuit board 1142 in the control box 114 for processing. If the flame is extinguished, the signal received by the circuit board 1142 will instruct the indicator 110 to issue a warning, reminding the user to take timely action.

[0083] Indicator 110 is electrically connected to circuit board 1142. Indicator 110 receives control signals from circuit board 1142 and then provides the user with indications of the flame status through visual feedback (such as LED indicator lights). Through its electrical connection to circuit board 1142, indicator 110 accurately reflects the signals processed by circuit board 1142. For example, the indicator light illuminates when the flame is normal and turns off when the flame is extinguished. This visual feedback allows the user to clearly understand the oven's operating status.

[0084] The control box 114 is located on one side of the oven housing 102 and is typically connected to the oven housing 102 by a fixing device (such as screws or clips). The fixed position of the control box 114 needs to ensure that its internal circuit board 1142 can effectively connect the detection cable 1084 and the indicator 110, while avoiding interference from high temperature or other adverse environmental factors. The control box 114 is usually located on the side, top, or bottom of the oven, which facilitates maintenance and operation, while ensuring the safe and effective operation of the circuit board 1142.

[0085] In some embodiments, the oven shell 102 may optionally include a movably connected oven body 1024 and a cover 1026, which together form a complete oven shell. Hinges or other movable connection methods are typically used to allow the cover 1026 to be easily opened and closed, facilitating not only operation but also cleaning and maintenance.

[0086] The movable connection design allows users to easily open the lid 1026 to place or turn food during use, and also enables quick cleaning of the interior after use. The airtight seal of the lid 1026 ensures heat retention and stable internal oven temperature.

[0087] The cooking opening 1022 of the oven is located on one side of the oven body 1024, serving as a passage for food to be placed in and removed, facilitating user operation, especially under high-temperature operating conditions. The position of the cooking opening 1022 allows users to safely and conveniently place and remove food, while ensuring maximum thermal efficiency. Other functional components of the oven (such as the burner 1042, flame detection device, etc.) are all concentrated near the cooking opening 1022, ensuring that heat is applied directly to the food.

[0088] The control panel 116 is positioned on the front of the oven body 1024, allowing users to easily see and operate all the oven's functions. The control panel 116 typically includes controls for temperature adjustment, time setting, and flame monitoring. This placement makes the oven's control buttons easily accessible and the operation more intuitive. Through the control panel 116, users can adjust the oven's operating parameters (such as temperature and time) in real time, enhancing ease of use and flexibility.

[0089] Indicator 110, such as an LED light or digital display, is located within the control panel 116 and is primarily used to display oven status information (such as whether the flame is normal, whether the temperature has reached the preset value, etc.). Indicator 110 can provide feedback on the flame status based on changes in the flame detection signal. The placement of indicator 110 allows users to easily observe the flame status through the control panel 116. When the flame is normal, indicator 110 illuminates; when the flame is extinguished, indicator 110 goes out, alerting the user to check and relight the flame. This provides users with real-time, intuitive feedback, helping to ensure the safe operation of the oven.

[0090] The oven body 1024 and the lid 1026 are connected by a movable connection structure (such as a hinge). The lid 1026 can be opened or closed as needed, facilitating the use and cleaning of the oven. The lid 1026 is located above the oven body 1024, opposite the oven's cooking opening 1022. The opening and closing of the lid 1026 does not affect the oven's heat circulation and combustion process, while providing good sealing.

[0091] The control panel 116 is mounted on the front side of the furnace body 1024 and is typically secured by screws or clips. The various buttons and indicators 110 on the control panel 116 are designed for easy user operation. The position of the control panel 116 is ergonomically designed, typically located in the central front area of ​​the furnace body 1024, ensuring that the user can easily access and view the information on the panel during operation.

[0092] Indicator 110 (such as an LED light or display screen) is electrically connected to control panel 116 and interacts with circuit board 1142. Indicator 110 displays information such as flame status and temperature. Indicator 110 is mounted on control panel 116, typically positioned at the top or center for easy viewing by the user. The indicator 110 within control panel 116 clearly displays the oven's operating status, allowing the user to understand whether the flame is functioning correctly.

[0093] In some embodiments, optionally, mounting holes 1162 are provided on the control panel 116 to facilitate the installation of the indicator 110. Specifically, the indicator 110 includes a lampshade structure 1102 and a light-emitting element 1104. The lampshade structure 1102 protects the light-emitting element 1104 and is detachably connected to the control panel 116, allowing the user to easily replace or maintain the light-emitting element 1104. The design of the lampshade structure 1102 ensures the safety of the light-emitting element 1104, while its detachability increases the ease of oven maintenance. The shape and material design of the lampshade also help diffuse the light, making the indicator light softer and more uniform, avoiding the stimulation of the user's eyesight by direct glare.

[0094] The control panel 116 has at least one mounting hole 1162. The lampshade structure 1102 is connected to these mounting holes 1162 via a detachable connection, ensuring that the lampshade is securely fixed to the control panel 116. The projection of the lampshade structure 1102 covers the mounting holes 1162, ensuring that the lampshade is installed accurately and fits tightly to the design of the control panel 116. This design not only ensures the stability of the lampshade but also optimizes the appearance of the control panel 116, making the oven more modern. The light-emitting element 1104 is installed inside the lampshade structure 1102 and is connected to the circuit board 1142 via an electrical connection. The lampshade structure 1102 effectively protects the light-emitting element 1104 and ensures that the light from the light-emitting element 1104 is evenly distributed. The light-emitting element 1104 is located inside the lampshade structure 1102, and the shape and size design of the lampshade ensures that the light-emitting element 1104 is clearly visible from the outside, and that the light propagation is not blocked or distorted by the lampshade.

[0095] The lampshade structure 1102 is detachably connected to the control panel 116, and the projection of the lampshade onto the control panel 116 covers the mounting holes 1162, ensuring a stable installation and compact structure. The mounting holes 1162 are well-designed, allowing the lampshade to be accurately aligned and securely fixed to the control panel 116. This detachable connection method simplifies assembly, disassembly, and maintenance. The mounting holes 1162 on the control panel 116 ensure the precise installation position of the lampshade, preventing loosening or misalignment between the lampshade and the control panel 116, and ensuring good visual effect and structural stability.

[0096] The light-emitting element 1104 is located within the lampshade structure 1102 and indicates the oven's operating status by emitting light. It is electrically connected to the circuit board 1142 and receives control signals from it to indicate whether the flame is functioning correctly. The light-emitting element 1104 is typically an LED light, characterized by long lifespan, low energy consumption, and good visual effects. The use of the light-emitting element 1104 not only provides clear feedback on the flame status (such as indicating whether the flame is functioning correctly by its on / off state) but also offers a good user experience. The brightness and color design of the LED light make it clearly visible under different lighting conditions. Through the light indicators on the control panel 116, the user can understand the oven's status immediately and make timely adjustments.

[0097] The light-emitting element 1104 is electrically connected to the circuit board 1142, which controls its on / off state. The circuit board 1142 controls the illumination of the light-emitting element 1104 based on signals from the flame detection system, providing feedback on whether the flame is functioning correctly. Through the control of the light-emitting element 1104 by the circuit board 1142, the system can automatically adjust the indicator light's brightness according to the flame's operating status. This connection makes the feedback on the flame status more real-time and accurate. Users can immediately determine whether the flame is functioning correctly by observing the status of the light-emitting element 1104, thus avoiding safety hazards caused by flame extinguishing.

[0098] In some embodiments, optionally, such as Figure 3 and Figure 4 As shown, a seal 118 is disposed between the lampshade structure 1102 and the control panel 116 to ensure a tight seal between the two. The shape of the seal 118 is adapted to the mounting hole 1162 on the control panel 116, so that it can effectively prevent air, moisture or dust from entering the oven, while preventing oil fumes or heat from escaping.

[0099] With this sealing design, the seal 118 can maintain a more stable environment inside the oven, reduce the entry of external contaminants into the control panel 116 area, and prevent excessive temperature or moisture from entering the circuit board 1142, thereby improving the safety and durability of the oven.

[0100] The primary purpose of the seal 118 is to prevent water, grease, or dust from seeping into the control panel 116. This is crucial for the long-term use of the oven, especially in high-temperature, high-humidity, or grease-filled environments. The seal 118 effectively prevents these external factors from affecting the circuit board 1142 and other sensitive components, extending the lifespan of the equipment. It also enhances the oven's protective performance, preventing electrical malfunctions caused by moisture or grease entering the internal circuitry.

[0101] The seal 118 is located between the lampshade structure 1102 and the control panel 116, and its shape perfectly matches the shape of the mounting hole 1162, ensuring that the seal 118 can be securely fixed between the two. This design ensures a tight connection between the two, preventing the ingress of air, moisture or dust.

[0102] The seal 118 is located around the mounting hole 1162 of the control panel 116, tightly wrapping around the connection between the lampshade structure 1102 and the control panel 116. This positioning effectively prevents external substances from entering, while not interfering with the installation and removal of the lampshade structure 1102.

[0103] In some embodiments, optionally, a floor support 120 is provided and positioned on the side of the oven body 1024 away from the cover 1026 to support the entire oven and provide a stable foundation. By installing the floor support 120 on one side of the oven body 1024, the weight of the entire oven is effectively distributed, thereby enhancing the stability and safety of the equipment. In particular, the support can provide additional support when moving or adjusting the position of the oven.

[0104] The 120-inch floor stand also reduces the direct contact between the bottom of the oven and the ground, thereby reducing wear and aging and extending the oven's lifespan.

[0105] The control box 114 is located on the side of the floor bracket 120 facing the oven housing 102. It is responsible for controlling the oven's electrical system, including temperature control, flame detection, and fan control. Its installation position is far from the cooking section of the oven to facilitate wiring and heat dissipation. The placement of the control box 114 ensures the safety and ease of maintenance of its internal circuit board 1142 and other electronic components. The control box 114, mounted on the floor bracket 120, avoids operation in high-temperature environments and facilitates user operation and adjustments.

[0106] The control box 114 is connected to various components of the oven (such as the flame detector 108, circuit board 1142, fan, etc.) via cables and control lines. With this setup, the control box 114 can receive information from various sensors in real time and adjust the oven's operating status accordingly.

[0107] In some embodiments, optionally, such as Figure 2 As shown, a control knob 122 is provided, and its combination with the indicator 110 increases the user's ease of operation and further enhances the safety and functionality of the oven. The control knob 122 is located on the control panel 116, and the user can adjust the operating status of at least one burner 1042 (such as ignition, adjusting the heat level, turning off burner 1042, etc.) by rotating the control knob 122. The knob design allows the user to operate the oven intuitively and easily.

[0108] By controlling knob 122, users can quickly adjust the heat output of burner 1042 to achieve precise temperature control, ensuring the oven can be effectively adjusted according to different cooking needs. Furthermore, control knob 122 not only controls the operation of burner 1042 but can also be indirectly linked to flame detector 108. When control knob 122 adjusts the heat or turns off burner 1042, flame detector 108 can immediately provide feedback on whether the flame has been extinguished, preventing danger caused by continued gas flow after the flame is extinguished. This linkage design ensures that no safety hazards such as gas leakage will occur after burner 1042 is turned off, increasing the oven's safety.

[0109] Indicator 110 is correspondingly located on control panel 116 and is used to display the flame's operating status. Changes in indicator 110 allow the user to intuitively determine whether burner 1042 is operating normally. The indicator 110 provides immediate feedback; a lit indicator means the flame is normal, and an unlit indicator means the flame is extinguished. This feedback mechanism effectively prevents gas leaks and helps users promptly identify and resolve problems.

[0110] When the control knob 122 adjusts the heat of the burner 1042 or turns off the burner 1042, the indicator 110 displays the flame status, indicating to the user whether the flame has gone out. This function significantly improves the safety of the oven. Users can promptly detect whether the oven is in normal working order; if the indicator light goes out, the user can immediately take measures to prevent gas leaks caused by flame extinguishing.

[0111] The control knob 122 is located on the control panel 116, opposite to the indicator 110. The control knob 122 adjusts the operating status of the burner 1042, while the indicator 110 provides real-time feedback on the flame status. Their close arrangement allows the user to clearly see the feedback information during operation. By placing the control knob 122 and indicator 110 on the control panel 116, the user can easily see the current flame status, and can directly control the operation of the burner 1042 by rotating the control knob 122, enhancing the oven's ease of use and intuitiveness.

[0112] The control knob 122 is mechanically or electrically connected to the burner 1042. When the user adjusts the knob, the burner 1042 adjusts accordingly. The indicator 110 is electrically connected to the flame detector 108. The flame detector 108 sends a signal to the indicator 110 based on the flame status, and the indicator 110 displays the corresponding flame status. The control knob 122 adjusts the fire output of the burner 1042, and the indicator 110 provides feedback on the flame status. These two mechanisms work in coordination to ensure that the user has a clear understanding of the oven's status and can react promptly.

[0113] Based on any of the above embodiments, optionally, such as Figure 9 As shown, a heat insulation element 124 is provided in the combustion chamber 104, specifically surrounding the burner 1042 and the flame detection element 108 which are arranged opposite to each other. This can isolate the burner 1042 and the flame detection element 108, so that on the one hand, the high temperature is prevented from directly acting on the flame detection element 108, which would affect its detection accuracy and stability, and on the other hand, the flame detection element 108 can accurately detect whether there is a flame in the burner 1042.

[0114] The flame detector 108 is typically composed of a thermocouple or other temperature sensing element, which is sensitive to temperature changes. High-temperature environments may cause the flame detector 108 to malfunction or produce errors. The heat insulation component 124 protects the flame detector 108 from high-temperature environments, thereby ensuring that the flame detection system accurately reflects the state of the flame.

[0115] The heat insulation component 124 effectively reduces the interference of heat generated by the burner 1042 on the flame detection component 108. Thus, the flame detection component 108 is only affected by the flame itself, and not by changes in the surrounding ambient temperature, improving the operational stability of the flame detection component 108 and enabling it to more accurately detect whether the flame has extinguished or is maintaining normal combustion. Stable detection results help prevent safety hazards caused by misjudgments, such as gas leaks.

[0116] By effectively isolating high temperatures, the heat insulation component 124 also reduces heat conduction outwards, thereby preventing external components from being affected by high temperatures. It also reduces damage or malfunction of other system components caused by excessive temperature. The oven maintains a high temperature during operation, and the function of the heat insulation component 124 is to ensure that the flame detection system and other related components operate within a safe temperature range, effectively reducing malfunctions or safety risks caused by overheating.

[0117] The design of the heat insulation component 124 effectively isolates the high temperature generated by the burner 1042 from the flame detection component 108, thereby improving the stability and accuracy of the flame detection system. It protects the flame detection component 108 from overheating, ensuring accurate detection of the flame state, thus avoiding safety issues such as gas leaks and enhancing the safety and operational stability of the oven.

[0118] In one specific embodiment, a structural design capable of detecting flames is provided. According to existing outdoor gas appliance standards, gas grills must be designed with a structure that allows observation / detection of flames. This is primarily because even when the flame extinguishes during combustion, the valve continues to operate, potentially leading to gas leakage and safety hazards. Most existing grill pans, in their design, often... Figure 8As shown, the frying pan 106' is suspended on the frame; although this structure is relatively simple, the suspended structure is prone to heat loss, the gas is not fully utilized, and the thermal efficiency is relatively low; or some use valve bodies with flameout protection, but the price is relatively expensive, the flameout protection valve body costs twice as much as the ordinary valve body.

[0119] This specific embodiment provides a new flame detection structure for detecting whether a flame has been extinguished, meeting outdoor gas appliance standards while embedding the frying pan inside the vehicle frame, such as... Figure 7 As shown, this improves gas usage efficiency and is reasonably priced; integrating electronic control components into the gas oven is more in line with the requirements of the smart era.

[0120] Specifically, this new flame detection structure is used to detect whether a flame has been extinguished, and includes a control panel, a sealing ring (i.e., a seal), self-tapping screws, a lampshade (i.e., a lampshade structure), an LED light (i.e., a light-emitting element), a circuit board, an indicator light harness, a thermocouple (i.e., a detection terminal), and a thermocouple harness (detection cable); such as Figure 2 As shown, the control panel is the main display area, and the flame detection light can remind the user whether the flame is working properly; for example... Figure 3 and Figure 4 As shown, install the LED light inside the lampshade (the lampshade has a snap-on structure; simply push the LED light in). Place the sealing ring on the lampshade, and then use self-tapping screws to secure the lampshade to the control panel. The overall structure has a waterproof design. Figure 1 , Figure 5 and Figure 6 As shown, connect the LED light to the indicator light harness, and connect the end of the indicator light harness to the circuit board. Then connect the thermocouple to the thermocouple harness, and connect the end of the harness to the circuit board. The circuit board is then... Figure 6 The microcontroller in the system is powered by a power supply connected to it. Data is collected via thermocouples, and the corresponding combustion status is displayed on an LCD. The thermocouples generate thermoelectric potential by sensing the flame, and then transmit the signal to the indicator light. The indicator light feeds the information back to the user. When the indicator light is on, it means that the flame is working normally, and when the indicator light is off, it means that the flame is extinguished.
