[0001] This application belongs to the field of gas device control technology, and in particular relates to a control method, device, equipment and medium for a gas device. Background Technology

[0002] With the continuous advancement of technology, heating methods are becoming increasingly diversified. Currently, the most popular heating methods on the market include heat pump heating, electric heating, and gas combustion heating, among which gas combustion heating still occupies a significant share of the heating market. However, in related technical fields, the control of gas combustion systems generally relies on complex mathematical models. These models aim to achieve material balance between gas and air, as well as proportional control of combustion balance. This method suffers from the problem of incomplete combustion.

[0003] Specifically, due to differences in control concepts and methods, the control methods for gas appliances in related technologies suffer from problems such as inaccurate control of the outlet air temperature parameter during gas combustion heating, potential ignition deflagration, and incomplete combustion of gas during multi-stage combustion. These problems not only threaten user safety but also increase the emission of harmful substances, pollute the environment, and waste valuable natural resources. Summary of the Invention

[0004] This application provides an implementation scheme that differs from related technologies, in order to solve the technical problems of potential ignition deflagration and incomplete combustion of gas in the gas device control methods of related technologies.

[0005] In a first aspect, this application provides a method for controlling a gas device, comprising:

[0006] In response to a heating signal, the exhaust fan is controlled to operate at a high speed for a first preset time. The exhaust fan has two speeds: low and high. The heating signal has two types: low heating signal and high heating signal.

[0007] After the first preset time is reached, the exhaust fan is controlled to run at a low speed, and the ignition needle is controlled to start preheating.

[0008] After the ignition needle reaches the preset temperature, the gas valve is controlled to operate at a low speed.

[0009] If successful ignition is detected, the gas valve and the exhaust fan are switched according to the type of the heating signal.

[0010] Secondly, this application provides a control device for a gas appliance, comprising:

[0011] The first control unit is used to control the exhaust fan to operate at a high speed for a first preset time in response to a heating signal, wherein the exhaust fan has a speed range including low speed and high speed, and the heating signal has a type including low speed heating signal and high speed heating signal.

[0012] The second control unit is used to control the exhaust fan to run at a low speed after the first preset time is reached, and at the same time control the ignition needle to start preheating.

[0013] The third control unit is used to control the gas valve to operate at a low speed after the ignition needle reaches the preset temperature.

[0014] The fourth control unit is used to control the gear switching of the gas valve and the exhaust fan based on the type of the heating signal if successful ignition is detected.

[0015] Thirdly, this application provides an electronic device, comprising:

[0016] Processor; and

[0017] Memory for storing the executable instructions of the processor;

[0018] The processor is configured to execute the first aspect, or any method in any possible implementation of the first aspect, by executing the executable instructions.

[0019] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the first aspect, or any method in any possible implementation of the first aspect.

[0020] This application provides a scheme that responds to a heating signal and controls an exhaust fan to operate at a high speed for a first preset time. The exhaust fan's speed settings include low and high, and the heating signal types include low and high heating signals. After the first preset time is reached, the exhaust fan is controlled to operate at low speed, and simultaneously, the ignition needle is controlled to begin preheating. After the ignition needle reaches a preset temperature, the gas valve is controlled to operate at low speed. If successful ignition is detected, the scheme controls the switching of the gas valve and exhaust fan speeds based on the type of heating signal. Before ignition, the exhaust fan is controlled... The machine operates at a high speed to purge any residual gas, including any leaked gas, from the gas passage cavity, preventing deflagration during subsequent ignition. After purging the residual gas, the gas valve is controlled to operate at a low speed to complete ignition, further preventing deflagration. After successful ignition, the gas valve and exhaust fan are switched according to the type of heating signal to ensure complete combustion of the gas, improve energy efficiency, and optimize the operating status of the gas device, thereby achieving the technical effects of preventing ignition deflagration and ensuring complete combustion of the gas.

[0030] Embodiments of this application are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting it.

[0031] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the solution can be implemented in a different order than that illustrated or described in this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] While heating methods have diversified with technological advancements, gas combustion heating still holds a significant market share. However, the control of gas combustion systems often relies on complex mathematical models, leading to problems such as incomplete combustion, inaccurate air outlet temperature control, ignition deflagration, and poor efficiency during multi-stage combustion. These issues threaten safety, increase pollution, and waste resources.

[0033] To address this technical problem, this application provides a control method, apparatus, equipment, and medium for a gas device, which solves the technical problems of potential ignition deflagration and incomplete combustion of gas in related gas device control methods.

[0034] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0035] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a control system for a gas appliance provided in an embodiment of this application. The system can implement a control method for the gas appliance. The control system may include a terminal 10 and a gas appliance 20. The terminal 10 and the gas appliance 20 can interact with each other via a network 30, which may be a wide area network (WAN), a local area network (LAN), or a combination of both.

[0036] In some embodiments, terminal 10 is used to generate a heating signal. Terminal 10 can be a smartphone or a control panel corresponding to a gas appliance. For example, a user sends a heating signal via a smart home app on a smartphone or a control panel on the wall. This heating signal can be a low-level heating signal or a high-level heating signal. Terminal 10 sends the heating signal to gas appliance 20 via network 30. In response to the received heating signal, gas appliance 20 controls the exhaust fan to operate at high speed for a first preset time. The exhaust fan's speed settings include low and high. Upon arrival, the gas device 20 controls the exhaust fan to operate at a low speed and simultaneously controls the ignition needle to begin preheating. After the ignition needle reaches the preset temperature, the gas device 20 controls the gas valve to operate at a low speed. If successful ignition is detected, the gas device 20 further controls the switching of the gas valve and exhaust fan speeds based on the type of heating signal. After the gas is ignited, high-temperature combustion gas is generated. The high-temperature combustion gas transfers heat to the air through the heat exchanger, thereby raising the indoor air temperature. The gas device 20 also controls the exhaust fan to continue operating, discharging the exhaust gas generated by combustion to the outside or the flue.

[0037] Please see Figure 2 , Figure 2 A schematic diagram of the structure of a gas device 10 provided for an exemplary embodiment of this application is shown. The structure includes a controller 100, a smoke exhaust fan 200, an igniter 300, a gas valve 400, etc. The control method of the gas device provided in this embodiment can be specifically executed by the controller 100 in the gas device 10, wherein:

[0038] The controller 100 is used to respond to a heating signal and control the exhaust fan 200 to operate at a high speed for a first preset time. The exhaust fan has two speed settings: low and high. The heating signal has two types: low-speed heating signal and high-speed heating signal. After the first preset time is reached, the controller controls the exhaust fan 200 to operate at a low speed and simultaneously controls the ignition needle 300 to start preheating. After the ignition needle 300 reaches a preset temperature, the controller controls the gas valve 400 to operate at a low speed. If successful ignition is detected, the controller controls the switching of the gas valve 400 and the exhaust fan 200 based on the type of heating signal.

[0039] The exhaust fan 200 is used to discharge the waste flue gas generated during the heating of the gas device to the outside or flue through multiple speed settings under the control of the controller 100.

[0040] Igniter 300 is used to generate high temperature under the control of controller 100 to ignite gas;

[0041] The gas valve 400 is used to supply gas through multiple gears under the control of the controller 100.

[0042] The execution principles and interaction processes of each component unit in this system embodiment, such as controller 100, exhaust fan 200, igniter 300, and gas valve 400, can be found in the descriptions of the following method embodiments.

[0043] Figure 3 The following is a flowchart illustrating a control method for a gas device provided as an exemplary embodiment of this application. This method can be applied to a controller 100 and includes at least the following steps S31-S34:

[0044] S31. In response to the heating signal, control the exhaust fan to run at high speed for a first preset time, wherein the exhaust fan speed includes low speed and high speed, and the heating signal type includes low speed heating signal and high speed heating signal.

[0045] Since there may be leaked gas in the gas passage cavity, the controller in the gas device responds to the heating signal and controls the exhaust fan to run at high speed for a first preset time. This allows the residual gas in the gas passage cavity to be emptied in a relatively short time, preventing ignition and deflagration.

[0046] Among them, the exhaust fan has a faster air speed when running at high speed and a slower air speed when running at low speed; the gas valve has a larger flow rate and pressure when running at high speed and a smaller flow rate and pressure when running at low speed.

[0047] In some embodiments, the first preset time is not less than a preset multiple of the residual gas venting time of the gas passage cavity of the gas device, and the calculation steps for the residual gas venting time include:

[0048] The exhaust rate is obtained by multiplying the exhaust port area by the exhaust fan speed when running at high speed.

[0049] Divide the volume of the gas passage cavity by the exhaust rate to obtain the residual gas venting time.

[0050] Specifically, the volume of the gas passage cavity inside the gas device is V, the area of ​​the exhaust port is S, and the wind speed of the exhaust fan when running at high speed is v1. Then, the exhaust rate of the exhaust fan when running at high speed is Q = S * v1, and the residual gas venting time of the gas passage cavity is Tb = V / Q.

[0051] In some embodiments, the preset multiple is greater than or equal to 2. Preferably, the preset multiple can be 4.

[0052] S32. After the first preset time is reached, control the exhaust fan to run at a low speed, and at the same time control the ignition needle to start preheating.

[0053] After the first preset time is reached, the residual gas in the gas passage cavity has been exhausted. Then the controller controls the exhaust fan to run at a low speed, and at the same time the controller controls the ignition needle to start preheating.

[0054] In some embodiments, the ignition needle is a surface-heating ignition needle.

[0055] S33. After the ignition needle reaches the preset temperature, control the gas valve to operate at a low speed.

[0056] After the ignition needle reaches the preset temperature, the controller controls the gas valve to operate at a low speed.

[0057] During ignition, controlling the gas valve to operate at a low setting can further prevent deflagration.

[0058] S34. If ignition is detected as successful, control the switching of the gas valve and exhaust fan based on the type of heating signal.

[0059] After the controller detects successful ignition, it will control the switching of the gas valve and exhaust fan based on the type of heating signal, which can make the gas combustion more complete and optimize the operation of the gas device.

[0060] In some embodiments, in S34, controlling the gas valve's gear switching based on the type of heating signal includes:

[0061] If the heating signal type is high-end heating signal, control the exhaust fan and gas valve to operate at high-end.

[0062] If the heating signal is a high-end heating signal, the controller will switch the operating level of the exhaust fan and gas valve from low to high, controlling the exhaust fan and gas valve to operate at high level to ensure sufficient gas supply and complete combustion of gas, reduce nitrogen oxide and carbon emissions, reduce environmental impact, and achieve clean combustion.

[0063] In other embodiments, in S34, controlling the gas valve's position switching based on the type of heating signal further includes:

[0064] If the heating signal type is low-level heating signal, maintain the exhaust fan and gas valve in low-level operation.

[0065] If the heating signal is a low-level heating signal, the gas valve can operate at a low level to ensure the gas supply. The controller does not switch the operating levels of the exhaust fan and the gas valve, thus improving energy efficiency.

[0066] In some embodiments, the method further includes the following S35-S36:

[0067] S35. Continuously monitor the speed of the smoke exhaust fan or the air pressure in the smoke exhaust duct;

[0068] During the operation of the smoke exhaust fan, the controller will continuously monitor the fan speed or the air pressure in the smoke exhaust duct to ensure the normal operation of the smoke exhaust fan.

[0069] Specifically, a wind pressure switch or wind pressure sensor can be used for detection.

[0070] S36. Report the operating status of the smoke exhaust fan based on the test results.

[0071] Specifically, if the test results indicate that the exhaust fan speed is abnormal or the exhaust duct pressure is abnormal, an alarm message indicating that the exhaust fan is blocked or the wind speed is abnormal will be reported.

[0072] In some embodiments, the method further includes the following S37:

[0073] S37. If the heating signal is a high-end heating signal, the blower is controlled to run at high-end after the second preset time from the successful ignition. If the heating signal is a low-end heating signal, the blower is controlled to run at low-end after the third preset time from the successful ignition.

[0074] Specifically, if the heating signal is a high-end heating signal, the controller will control the blower to run at high speed after a second preset time from the moment of successful ignition; if the heating signal is a low-end heating signal, the controller will control the blower to run at low speed after a third preset time from the moment of successful ignition.

[0075] The second and third preset times can be set reasonably according to the actual scenario, and this application does not impose any restrictions on them.

[0076] See also Figure 2 The blower 500 is connected to the controller 100 and is used to deliver indoor recirculated air and / or outdoor fresh air to the heat exchanger 600.

[0077] In some embodiments, in response to a heating signal, before controlling the operation of the exhaust fan, the method further includes the following steps S38-S39:

[0078] S38. Check whether the status of each component in the gas device is normal;

[0079] S39. If the test results indicate that all components are in normal condition, control the exhaust fan to run at high speed. If the test results indicate that there is a faulty component, report the faulty component.

[0080] Specifically, in response to the heating signal, the controller first checks each component in the gas device to complete the self-check of the gas device and ensure its normal operation. If the test results indicate that all components are in normal condition, the controller controls the exhaust fan to run at high speed. If the test results indicate that there is a faulty component, the controller will report the faulty component and will not control the exhaust fan and gas valve to start.

[0081] In some embodiments, the method further includes: controlling the speed switching of the gas valve and the exhaust fan according to the indoor temperature.

[0082] In some embodiments, the method further includes: if flame extinguishing is detected, controlling the various components included in the gas device to stop operating.

[0083] If the flame is detected to be extinguished, the control system stops all components in the gas appliance, automatically shutting down the furnace to ensure user safety.

[0084] Please see Figure 4 and Figure 5 , Figure 4 A timing diagram of a control method for a gas device when the heating signal is a low-level heating signal, as provided in an embodiment of this application. Figure 5 This is a timing diagram illustrating the control method of a gas device when the heating signal is a high-end heating signal, as provided in the embodiments of this application. In this diagram, signal W1 is a low-end heating signal, W2 is a high-end heating signal, HI indicates that the component is operating at a high-end setting, and LO indicates that the component is operating at a low-end setting.

[0085] According to the timing diagram provided in this application, after the heating signal disappears, the exhaust fan will continue to run for a period of time to perform the post-sweeping process, which is used to exhaust the remaining waste gas in the gas device; after the heating signal disappears, the blower and the air pressure switch will also run for a period of time.

[0086] In response to the heating cancellation signal, the exhaust fan, supply fan, and air pressure switch will each stop operating after a certain delay.

[0096] S69. Control the ignition needle to start preheating;

[0100] S613. After a period of time from the moment of successful ignition, control the blower to run at high speed;

[0101] S614. Keep the exhaust fan and gas valve running at low speed;

[0102] S615. After a period of time from the moment of successful ignition, control the blower to run at a low speed.

[0103] This application provides a scheme that responds to a heating signal and controls an exhaust fan to operate at a high speed for a first preset time. The exhaust fan's speed settings include low and high, and the heating signal types include low and high heating signals. After the first preset time is reached, the exhaust fan is controlled to operate at low speed, and simultaneously, the ignition needle is controlled to begin preheating. After the ignition needle reaches a preset temperature, the gas valve is controlled to operate at low speed. If successful ignition is detected, the scheme controls the switching of the gas valve and exhaust fan speeds based on the type of heating signal. Before ignition, the exhaust fan is controlled... The machine operates at a high speed to purge any residual gas, including any leaked gas, from the gas passage cavity, preventing deflagration during subsequent ignition. After purging the residual gas, the gas valve is controlled to operate at a low speed to complete ignition, further preventing deflagration. After successful ignition, the gas valve and exhaust fan are switched according to the type of heating signal to ensure complete combustion of the gas, improve energy efficiency, and optimize the operating status of the gas device, thereby achieving the technical effects of preventing ignition deflagration and ensuring complete combustion of the gas.
