Description

Technical Field

[0001] This utility model relates to the technical field of stove-related equipment, and in particular to a stove with an accidental flameout protection device. Background Technology

[0002] With the increasing popularity of household gas stoves, the safety of their use is receiving more and more attention. When the operator is not present and the flame is extinguished due to unexpected situations such as wind or boiling water overflowing, measures must be taken to prevent the leakage of flammable gases such as coal gas or natural gas. Among these measures, a flameout protection device is required.

[0003] Currently, most existing stoves with accidental flameout protection devices achieve their effect using the following technologies;

[0004] Sensing technologies include thermocouple sensing technology, ion sensing technology, and photoelectric sensing technology;

[0005] Switching technology, including solenoid valve switching and power switch control;

[0006] Control technologies, including PLC control technology, are used to control the electrical equipment in stoves.

[0007] Currently, existing stoves equipped with accidental flameout protection devices have been found to have at least the following technical problems during actual use;

[0008] Currently, most existing stoves with accidental flameout protection devices use sensors in conjunction with valves to cut off gas supply when the stove goes out. However, most of these devices lack an alarm mechanism, only cutting off the gas supply without alerting the user. If the valve is damaged and cannot close automatically, the protection device will not function, and gas will still be released from the stove. Without user intervention, this poses a significant danger. Therefore, existing devices still pose a certain degree of danger in actual use. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a stove with an accidental flameout protection device, solving the problem that existing devices pose a danger in actual use.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A stove with an accidental flameout protection device includes a stovetop and a gas pipeline. The top surface of the stovetop has two burners, and the bottom surface of the stovetop has a circuit controller. The circuit controller includes a control chip, an electronic control unit, and a communication unit. The top surface of the stovetop also has two control switches. The stovetop is characterized by having a gas delivery mechanism at the bottom and an alarm mechanism at the top. The gas delivery mechanism includes a Y-shaped diverter pipe, a main solenoid valve, two auxiliary solenoid valves, and two guide pipes. The alarm mechanism includes a mounting bracket, a speaker, and a flashing alarm light.

[0012] Preferred configuration: The mounting bracket is fixedly installed on the top surface of the stove, and a conduit is fixedly connected to the bottom of the mounting bracket. The end of the conduit away from the mounting bracket is fixedly connected to the circuit controller.

[0013] Preferably, both the speaker and the flashing alarm light are fixedly connected to the side of the mounting bracket facing the stove, and both the speaker and the flashing alarm light are electrically connected to the circuit controller through flexible wires passing through the mounting bracket and conduit.

[0014] Preferably, the top surface of the mounting bracket is fixedly connected to two damping shafts. The ends of the two damping shafts away from the mounting bracket are fixedly connected to photoelectric sensors. The two photoelectric sensors face the two burners respectively. Both photoelectric sensors are electrically connected to the circuit controller through flexible lines passing through the mounting bracket and conduit.

[0015] Preferably, a combustible gas sensor is fixedly connected to the side of the mounting bracket away from the speaker, and a communication antenna is also fixedly connected to the side of the mounting bracket away from the speaker. Both the communication antenna and the combustible gas sensor are electrically connected to the circuit controller through flexible wires passing through the mounting bracket and conduit. The combustible gas sensor is used to detect combustible gas in the environment when the photoelectric sensor fails, which increases safety. The communication antenna, together with the communication module in the circuit controller, sends a gas leak signal to the user's mobile phone.

[0016] Preferably, a reset button is fixedly installed on the side wall of the mounting bracket. The reset button is electrically connected to the circuit controller through a flexible wire passing through the mounting bracket and the conduit. It is used to reset the speaker and the flashing alarm light, so that the speaker and the flashing alarm light stop alarming.

[0017] Preferably, the Y-shaped diverter is fixedly connected to the gas pipeline, and the middle section of the Y-shaped diverter is fixedly connected to the main solenoid valve.

[0018] Preferably, the two ends of the Y-shaped diverter pipe away from the gas pipeline are fixedly connected to the gas inlets of the two auxiliary solenoid valves, the gas outlets of the two auxiliary solenoid valves are fixedly connected to the two guide pipes, the ends of the two guide pipes away from the auxiliary solenoid valves are connected to the two burners, the main solenoid valve and the two auxiliary solenoid valves are electrically connected to the circuit controller, and the two control switches are electrically connected to the circuit controller.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] I. In this application, when the burner is accidentally extinguished, the corresponding photoelectric sensor will detect that the burner is in an extinguished state and send an electrical signal to the circuit controller. After receiving the signal, the circuit controller will determine whether the gas is being discharged based on the on / off state of the auxiliary solenoid valve. If the auxiliary solenoid valve is in the gas-venting state, it will close the auxiliary solenoid valve, activate the speaker to emit an alarm sound, and activate the flashing red and blue light to remind the user to check the stove. This solves the problem that existing devices are dangerous in actual use.

[0021] Second, in this application, if the circuit controller has already controlled the auxiliary solenoid valve to the gas cut-off state, but the auxiliary solenoid valve is accidentally damaged and cannot be closed, the gas will continue to leak. The photoelectric sensor can only detect the flame but cannot detect the gas leak. At this time, the combustible gas sensor can play the role of detecting the gas. If the combustible gas sensor detects that the gas concentration in the environment exceeds the preset value, the circuit controller will automatically control the main solenoid valve to the closed state. The possibility of the main solenoid valve and the auxiliary solenoid valve being damaged at the same time is low. Therefore, this application has a backup protection measure, which makes this application highly safe. Attached Figure Description

[0042] Circuit controller 102: includes a control chip, an electronic control unit and a communication unit. It is the control core of the stove. It receives signals from the photoelectric sensor 303 and the combustible gas sensor 305, and controls the opening and closing of the main solenoid valve 202 and the auxiliary solenoid valve 203, as well as the working status of the alarm mechanism 3 according to the signals.

[0050] Photoelectric sensor 303: mounted on mounting bracket 301 via damping shaft 302, facing the burner 101, used to detect the flame status of burner 101, and send an electrical signal to circuit controller 102 when burner 101 is accidentally extinguished.

It is used to protect and guide the flexible circuit connecting the various components to the circuit controller 102, so that the circuit is neat and safe.

[0057] Working principle:

[0058] The first step involves controlling the opening and closing of two auxiliary solenoid valves 203 via two control switches 103. The main solenoid valve 202 is normally open. Turning one of the control switches 103 can control the corresponding burner 101 to start ignition. When the burner 101 is accidentally extinguished, the corresponding photoelectric sensor 303 will detect that the burner 101 is in an extinguished state and will send an electrical signal to the circuit controller 102. After receiving the signal, the circuit controller 102 will determine whether the gas is being discharged based on the opening and closing status of the auxiliary solenoid valves 203. If the auxiliary solenoid valves 203 are in a gas-flowing state, the auxiliary solenoid valves 203 will be closed, and the speaker 306 will be activated to sound an alarm. The flashing alarm light 307 will be activated to flash red and blue lights, and a notification will be sent to the user's mobile phone via the communication unit (the specific program can be customized by the manufacturer). The user can control the main solenoid valve 202 to close via the mobile phone, further preventing gas flow and preventing the auxiliary solenoid valves 203 from malfunctioning.

[0059] Secondly, in this application, if the circuit controller 102 has already controlled the auxiliary solenoid valve 203 to the gas cut-off state, but the auxiliary solenoid valve 203 is accidentally damaged and cannot be closed, the gas will continue to leak. The photoelectric sensor 303 can only detect the flame but cannot detect the gas leak. At this time, the combustible gas sensor 305 can detect the gas. If the combustible gas sensor 305 detects that the gas concentration in the environment exceeds the preset value, the circuit controller 102 will automatically control the main solenoid valve 202 to the closed state. The possibility of the main solenoid valve 202 and the auxiliary solenoid valve 203 being damaged at the same time is low. Therefore, this application has a backup protection measure, which makes this application highly safe.

[0060] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
