Description

Technical Field

[0001] This invention relates to the field of fully premixed combustion technology, and in particular to an ignition control method for a blower-type fully premixed gas stove. Background Technology

[0002] Fully premixed combustion is a novel combustion method. Compared to traditional atmospheric combustion, it offers advantages such as more complete combustion, higher combustion temperature, higher thermal efficiency, and lower harmful emissions. Currently, gas stoves using the blower-type fully premixed combustion system are primarily used in commercial applications. Household blower-type systems have not seen widespread adoption due to limitations imposed by the operating environment, structure, and energy efficiency standards. Unlike atmospheric combustion stoves, which adaptively inject primary air for mixing based on power output and then supplement with secondary air, blower-type fully premixed household gas stoves use a blower to provide all the necessary air (oxygen) for combustion. Therefore, at the same power output, the gas-air mixture in a fully premixed burner flows very rapidly at the burner outlet, frequently resulting in flameout when cold and making ignition extremely difficult. Summary of the Invention

[0003] This invention provides a blower-type fully premixed gas stove and its ignition control method, the main purpose of which is to solve the problem of difficult ignition of blower-type fully premixed household gas stove in cold state.

[0004] To achieve the above objectives, the present invention provides a forced-draft fully premixed gas stove, comprising:

[0005] The controller is connected to the pressure vessel detection device pin and the blower via wires;

[0006] The burner detection device pin is detachably mounted on the burner;

[0007] The blower is connected to the burner through an air supply inlet to provide sufficient air to the burner.

[0008] As a further improvement of the present invention, the blower is provided with an air inlet pipe, and a pressure regulating valve is installed on the air inlet pipe.

[0009] As a further improvement of the present invention, the bottom of the burner is connected to the controller via a line, and the presence of a pot on the gas stove is determined by the connection status of the line.

[0010] As a further improvement of the present invention, the specific steps for determining whether there is a pot on the gas stove by the connection status of the circuit include:

[0011] When the pot-sitting detection device pin is pressed down, the wire line between the pot-sitting detection device pin and the controller is connected, confirming that there is a pot sitting on the gas stove.

[0012] When the pot-sitting detection device pin is not pressed down, the wire connection between the pot-sitting detection device pin and the controller is disconnected, indicating that there is no pot sitting on the gas stove.

[0013] This invention also proposes an ignition control method for a forced-draft fully premixed gas stove, the method comprising:

[0014] The controller sends the user's ignition information to the pin of the pot detection device;

[0015] The real-time status of the pin of the pot-sitting detection device determines whether there is a pot sitting on the gas stove.

[0016] When a pot is placed on the gas stove, the controller controls the blower to run at a first speed.

[0017] When there is no pot on the gas stove, the controller controls the blower to run at a second speed for a preset duration;

[0018] After the blower has been running at the second speed for the preset duration, the blower then runs at the first speed.

[0019] As a further improvement of the present invention, the real-time status determination of the burner pin of the pot-sitting detection device for whether a pot is sitting on the gas stove includes:

[0020] If the pin of the pot-sitting detection device is in a depressed state, it is determined that there is a pot sitting on the gas stove.

[0021] If the pin of the pot-sitting detection device is not in the pressed-down state, it is determined that there is no pot sitting on the gas stove.

[0022] As a further improvement of the present invention, the controller controls the blower to operate at a first speed, including:

[0023] Real-time acquisition of the gas flow rate of the burner;

[0024] The amount of air that matches the gas flow rate is calculated based on a preset mixing ratio;

[0025] The target speed of the blower is calculated based on the air volume, and the target speed is determined to be the first speed.

[0026] As a further improvement of the present invention, the step of calculating the air volume matching the gas flow rate according to a preset mixing ratio includes:

[0027] The air volume matching the gas flow rate is calculated using the following proportional formula:

[0028] x=y*n

[0029] Where x is the amount of fuel gas, y is the amount of air, and n is a constant.

[0030] As a further improvement of the present invention, within a preset time period during which the controller controls the blower to operate at a second speed, the method further includes:

[0031] The pressure plate detection device continuously detects whether the pressure plate is being pressed down.

[0032] When the pressure of the bottom pin of the pot detection device is detected, the controller controls the blower to change from the second speed to the first speed.

[0033] The technical problem solved by this invention is:

[0034] Solve the problem of cold-state ignition difficulty in blower-type fully premixed household gas stoves.

[0035] The beneficial effects of this invention are as follows:

[0036] When igniting in a cold, potless state, reduce the fan speed to provide slightly less air than required for fully premixed combustion, thereby reducing the flameout limit and increasing the success rate. When the pot is present, it can operate at the speed required for fully premixed combustion, avoiding incomplete combustion caused by the pot being in a pot-supported state, which would produce excessive amounts of harmful gases such as carbon monoxide.

[0059] This application provides a blower-type fully premixed gas stove. The blower-type fully premixed gas stove...

[0060] It can solve the problems of easy flameout and difficulty in ignition in cold state of blower-type fully premixed household gas stoves, and ensure that the ignition success rate and toxic combustion products meet the requirements when there is a pot on the stove or no pot.

[0061] Example 1:

[0062] Reference Figure 1 The diagram shown is a structural schematic of a forced-draft fully premixed gas stove according to an embodiment of the present invention. In this embodiment, the forced-draft fully premixed gas stove includes:

[0063] Gas valve 70 and controller 10;

[0064] The controller 10 is connected to the boiler detection device pin 20 and the blower 30 via wires;

[0065] The burner 60 is detachably mounted on the burner 60 by the burner pin 20 of the boiler detection device.

[0066] The blower 30 is connected to the burner 60 through an air supply inlet to provide sufficient air to the burner 60.

[0067] In detail, the controller 10 is connected to the boiler detection device pin 20 and the blower 30 via wires. The controller 10 can be used to receive and process data, and then issue control commands to other components based on the results of receiving and processing the data.

[0068] Specifically, the controller 10 contains circuit board components capable of transmitting electrical signals and a computer program capable of receiving and processing data. When external data is received, the controller processes the data and issues control commands to other components (such as the burner 60 or the blower 30) based on the processing results.

[0069] Furthermore, the burner 60 is detachably mounted on the boiler detection device pin 20 by means of snap-fit, ring-fit, or engagement, so as to facilitate separate disassembly and replacement of the burner 60 or the boiler detection device pin 20 when damaged.

[0070] Specifically, when the pot-sitting detection device pin 20 is pressed down, the wires between the pot-sitting detection device pin 20 and the controller 10 are connected, confirming that there is a pot sitting on the gas stove.

[0071] Alternatively, if the pot-sitting detection device pin 20 is not pressed down, the wire connection between the pot-sitting detection device pin 20 and the controller 10 is disconnected, thus determining that there is no pot sitting on the gas stove.

[0072] Furthermore, the bottom of the burner 60 is connected to the controller 10 via a circuit. The controller 10 determines whether a pot is on the gas stove by detecting the continuity of the circuit between itself and the pot-sitting detection device pin 20, and issues a corresponding command to the burner 60 to perform an ignition operation based on the detection result. Specifically, the gas valve 70 is used to control the gas flow on and off.

[0073] Reference Figure 3 The diagram shown illustrates the structure of a forced-draft fully premixed gas stove with an outer casing, as provided in an embodiment of the present invention. In this embodiment, the structure of the forced-draft fully premixed gas stove with an outer casing includes: a pot-sitting detection device pin 20 and a pot-sitting detection device pin 21.

[0074] Reference Figure 5 The image shown is a top view of a blower-type fully premixed gas stove with its outer casing, as provided in an embodiment of the present invention.

[0075] Working principle:

[0076] In this embodiment of the invention, when the user opens the gas valve 70, whether the circuit between the controller 10 and the pot-sitting detection device pin 20 is connected depends on whether the pot-sitting detection device pin 20 is pressed down.

[0077] If the pressure pin 20 of the pot-sitting detection device is pressed down, it is confirmed that a pot is sitting, and the circuit between the controller 10 and the pressure pin 20 of the pot-sitting detection device is connected.

[0078] If the pressure pin 20 of the pot-sitting detection device is not pressed down, it is confirmed that there is no pot sitting, and the line between the controller 10 and the pressure pin 20 of the pot-sitting detection device is disconnected.

[0079] Furthermore, the controller 10 determines whether the circuit between itself and the boiler detection device pin 20 is connected, and controls the burner 60 to ignite. Further, the air supply inlet is connected to the blower 30, the burner 60, and the gas valve 70 via a pipe. The gas and the air required for combustion are mixed at the air supply inlet, preparing the burner 60 for fully premixed combustion.

[0080] Example 2:

[0081] Because of changes in the external airflow during gas combustion, the air-gas mixture ratio fluctuates, leading to incomplete combustion, the production of toxic and harmful substances, and gas waste.

[0082] Reference Figure 2 As shown, in the second embodiment of the present invention, a blower-type fully premixed gas stove with a pressure regulating valve 40 is provided, the specific structure of which includes:

[0083] Gas valve 70 and controller 10;

[0084] The controller 10 is connected to the boiler detection device pin 20 and the blower 30 via wires;

[0085] The burner 60 is detachably mounted on the burner 60 by the burner pin 20 of the boiler detection device.

[0086] The blower 30 is connected to the burner 60 through an air supply inlet, and is used to provide sufficient air to the burner 60.

[0087] The blower 30 is provided with an air inlet pipe 50, and a pressure regulating valve 40 is installed on the air inlet pipe 50.

[0088] In detail, the controller 10 is connected to the boiler detection device pin 20 and the blower 30 via wires. The controller 10 can be used to receive and process data, and then issue control commands to other components based on the results of receiving and processing the data.

[0089] Specifically, the controller 10 contains circuit board components capable of transmitting electrical signals and a computer program capable of receiving and processing data. When external data is received, the controller processes the data and issues control commands to other components (such as the burner 60 or the blower 30) based on the processing results.

[0090] Furthermore, the burner 60 is detachably mounted on the boiler detection device pin 20 by means of snap-fit, ring-fit, or engagement, so as to facilitate separate disassembly and replacement of the burner 60 or the boiler detection device pin 20 when damaged.

[0091] Specifically, when the pot-sitting detection device pin 20 is pressed down, the wires between the pot-sitting detection device pin 20 and the controller 10 are connected, confirming that there is a pot sitting on the gas stove.

[0092] Alternatively, if the pot-sitting detection device pin 20 is not pressed down, the wire connection between the pot-sitting detection device pin 20 and the controller 10 is disconnected, thus determining that there is no pot sitting on the gas stove.

[0093] Furthermore, the bottom of the burner 60 is connected to the controller 10 via a circuit. The controller 10 then determines whether a pot is sitting on the gas stove by detecting whether the circuit between the burner 60 and the pot-sitting detection device pin 20 is connected, and issues a corresponding command to the burner 60 to perform an ignition operation based on the detection result.

[0094] Specifically, the gas valve 70 is used to control the opening and closing of the gas supply.

[0095] It should be noted that the blower 30 is connected to the burner 60 through an air supply inlet to provide the burner 60 with the air required for fully premixed combustion, so as to ensure that there is sufficient oxygen during combustion and improve the safety of combustion. The speed of the blower 30 is controlled by the controller 10.

[0096] Reference Figure 4 As shown, in the second embodiment of the present invention, a blower-type fully premixed gas stove with a pressure regulating valve 40 is provided. Figure 4 This is a top view of the gas stove, and its specific structure includes:

[0097] Gas valve 70 and controller 10;

[0098] The controller 10 is connected to the bottom plate detection device pin 20, the bottom plate detection device pin 21, the blower 30, and the blower 31 via wires.

[0099] The burner 60 is detachably mounted on the burner 60 by the burner pin 20 of the boiler detection device.

[0100] The blower 30 is connected to the burner 60 through an air supply inlet, and is used to provide sufficient air to the burner 60.

[0101] The blower 30 is provided with an air inlet pipe 50, and a pressure regulating valve 40 is installed on the air inlet pipe 50.

[0102] Working principle:

[0103] In this embodiment of the invention, when the user opens the gas valve 70, whether the circuit between the controller 10 and the pot-sitting detection device pin 20 is connected depends on whether the pot-sitting detection device pin 20 is pressed down.

[0104] If the pressure pin 20 of the pot-sitting detection device is pressed down, it is confirmed that a pot is sitting, and the circuit between the controller 10 and the pressure pin 20 of the pot-sitting detection device is connected.

[0105] If the pressure pin 20 of the pot-sitting detection device is not pressed down, it is confirmed that there is no pot sitting, and the line between the controller 10 and the pressure pin 20 of the pot-sitting detection device is disconnected.

[0106] Then, the controller 10 determines whether the circuit between itself and the burner pin 20 of the pot detection device is connected, and controls the burner 60 to ignite.

[0107] Furthermore, the air supply inlet is connected to the blower 30, the burner 60, and the gas valve 70 via a pipe. The gas and the air required for combustion are mixed at the air supply inlet. The blower 30 is equipped with an air inlet pipe 50, and a pressure regulating valve 40 is installed on the air inlet pipe 50. The pressure regulating valve provides a stable pressure (i.e., gas flow rate) for the burner 60 to perform fully premixed combustion during combustion.

[0108] Reference Figure 6 As shown in the figure, an ignition control method for a blower-type fully premixed gas stove is provided according to an embodiment of the present invention. In this embodiment, the device includes:

[0109] Gas valve 70 and controller 10;

[0110] The controller 10 is connected to the boiler detection device pin 20 and the blower 30 via wires;

[0111] The burner 60 is detachably mounted on the burner 60 by the burner pin 20 of the boiler detection device.

[0112] The blower 30 is connected to the burner 60 through an air supply inlet to provide sufficient air to the burner 60.

[0113] In detail, the controller 10 is connected to the boiler detection device pin 20 and the blower 30 via wires. The controller 10 can be used to receive and process data, and then issue control commands to other components based on the results of receiving and processing the data.

[0114] Specifically, the controller 10 contains circuit board components capable of transmitting electrical signals and a computer program capable of receiving and processing data. When external data is received, the controller processes the data and issues control commands to other components (such as the burner 60 or the blower 30) based on the processing results.

[0115] Furthermore, the burner 60 is detachably mounted on the boiler detection device pin 20 by means of snap-fit, ring-fit, or engagement, so as to facilitate separate disassembly and replacement of the burner 60 or the boiler detection device pin 20 when damaged.

[0116] The method includes:

[0117] S1. The controller 10 sends the user's ignition information to the pot detection device pin 20.

[0118] In this embodiment of the invention, the ignition information may be a current signal.

[0119] The user can send the ignition information to the pot detection device pin 20 by opening the gas valve 70 using the controller 10. The pot detection device pin 20 receives the ignition information through the wire connected to the controller 10.

[0120] S2. The real-time status of the pot-sitting detection device pin 20 determines whether there is a pot sitting on the gas stove.

[0121] In this embodiment of the invention, the pin 20 of the pot-sitting detection device can determine whether there is a pot sitting on the corresponding position of the gas stove based on its own downward pressure state.

[0122] In this embodiment of the invention, the real-time status determination of the burner pin 20 of the pot-sitting detection device for whether a pot is sitting on the gas stove includes:

[0123] If the pin 20 of the pot-sitting detection device is in a depressed state, it is determined that there is a pot sitting on the gas stove.

[0124] If the pin 20 of the pot-sitting detection device is not in a depressed state, it is determined that there is no pot sitting on the gas stove.

[0125] In detail, if there is a pot sitting on the gas stove, the pot sitting detection device pin 20 will be in a depressed state, thereby connecting the wires between the pot sitting detection device pin 20 and the controller 10.

[0126] However, if there is no pot on the gas stove, the pot detection device pin 20 will not be in a depressed state, thus disconnecting the wiring between the pot detection device pin 20 and the controller 10.

[0127] Therefore, in this embodiment of the invention, the pin 20 of the pot-sitting detection device can determine whether there is a pot sitting on the gas stove based on whether it is in a downward pressing state.

[0128] In this embodiment of the invention, the pressure state of the pin 20 of the pot detection device is used to quickly determine whether there is a pot at the corresponding position of the gas stove. Then, different control schemes are implemented for the pot-containing state and the pot-free state to reduce the probability of subsequent ignition failure.

[0129] When a pot is placed on the gas stove, S3 is executed, and the controller 10 controls the blower 30 to run at a first speed.

[0130] In this embodiment of the invention, when the pressure pin 20 of the pot-sitting detection device is in the downward state, the pressure pin 20 of the pot-sitting detection device will send a current signal to the controller 10. After receiving the current signal, the controller 10 controls the blower 30 to run at a preset first speed to achieve air supply to the burner 60, so that the burner 60 can perform fully premixed combustion.

[0131] In this embodiment of the invention, the first rotational speed is a preset rotational speed, and the blower 30 can provide an air volume that matches the gas flow rate at the first rotational speed, thus satisfying the conditions for fully premixed combustion.

[0132] Specifically, the controller 10 controls the blower 30 to operate at a first speed, including:

[0133] Real-time acquisition of the gas flow rate of the burner 60;

[0134] The amount of air that matches the gas flow rate is calculated based on a preset mixing ratio;

[0135] The target rotational speed of the blower 30 is calculated based on the air volume, and the target rotational speed is determined to be the first rotational speed.

[0136] Specifically, the step of calculating the air volume matching the gas flow rate based on a preset mixing ratio includes:

[0137] The air volume matching the gas flow rate is calculated using the following proportional formula:

[0138] x=y*n

[0139] Where x is the amount of fuel gas, y is the amount of air, and n is a constant.

[0140] In detail, the first rotational speed can also be calculated and determined based on the actual power of the product in actual use. The rotational speed is related to the current, which can be provided by the controller 10.

[0141] Specifically, when a pot is placed on the gas stove, a combustion chamber is formed between the pot and the burner 60, which causes the gas mixture ejected from the burner 60's flame holes to be resisted, resulting in a reduced flow rate and making it difficult to escape, thus increasing the flameout limit.

[0142] Therefore, the blower 30 operates at the first speed at this time, providing the burner 60 with an air volume that matches the gas flow rate, thereby reducing the probability of flameout.

[0143] In this embodiment of the invention, the fully premixed combustion refers to the process of fully mixing the fuel gas and air before they enter the burner to form a uniform mixed gas. This combustion method can greatly improve combustion efficiency and reduce the generation of harmful substances.

[0144] In this embodiment of the invention, when a pot is detected at the corresponding position of the gas stove, the blower 30 operates at the first speed, directly providing the burner 60 with an air volume matching the gas flow rate, thereby ensuring the success rate of ignition, reducing the generation of harmful substances, and improving combustion efficiency.

[0145] When there is no pot on the gas stove, S4 is executed, and the controller 10 controls the blower 30 to run at the second speed for a preset time.

[0146] In this embodiment of the invention, the second rotational speed is a preset rotational speed. The blower 30 provides an air volume slightly lower than the gas flow rate required for fully premixed combustion at the second rotational speed, which does not meet the conditions for fully premixed combustion.

[0147] In detail, the second speed is related to the first speed, but the second speed is lower than the first speed. The specific speed needs to be determined based on actual testing.

[0148] Specifically, in the boiler-free state, the blower 30 supplies the burner 60 with an air volume slightly lower than the gas flow rate required for fully premixed combustion at the second rotational speed. At this time, the gas-air mixture ejected from the burner 60 has a low gas concentration and low velocity, reducing the flameout limit. Because it is a boiler-free state, it is an open combustion system; the air required for the complete combustion of the remaining gas mixture is supplemented by secondary air, preventing the generation of excessive harmful combustion products.

[0149] In this embodiment of the invention, the preset duration is a pre-set time.

[0150] Specifically, within a preset time period during which the controller 10 controls the blower 30 to operate at a second speed, the method further includes:

[0151] The pressure pin 20 of the pot-sitting detection device continuously detects whether it is being pressed down;

[0152] When the pressure of the pressure plate detection device pin 20 is detected, the controller 10 controls the blower 30 to change from the second speed to the first speed.

[0153] If the gas stove remains without a pot within the preset time period, the blower 30 will run at the second speed, and at this time the pot detection device pin 20 will continuously detect whether there is a pot on the gas stove.

[0154] If the user places the pot on the gas stove within the preset time period, and the pot detection device pin 20 is pressed down, the controller will immediately control the blower 30 to run at the first speed.

[0155] In this embodiment of the invention, when it is determined that there is no pot at the corresponding position of the gas stove, the blower 30 runs at the second speed for the preset duration, thereby improving the success rate of ignition.

[0156] When the blower 30 runs at the second speed, execute S5 to determine whether the blower 30 has run at the second speed for the preset duration.

[0157] In this embodiment of the invention, the controller 10 determines whether the blower 30 has operated at the second speed for the preset duration. The controller 10 compares the duration of operation at the second speed with the preset duration. If the duration of operation at the second speed is less than the preset duration, it is determined that the blower 30 has not operated at the second speed for the preset duration. If the duration of operation at the second speed is greater than or equal to the preset duration, it is determined that the blower 30 has operated at the second speed for the preset duration.

[0158] If the blower 30 has not run at the second speed for the preset duration, the controller 10 continues to perform the judgment.

[0159] When the blower 30 runs at the second speed for the preset duration, S6 is executed, and the blower 30 runs at the first speed.

[0160] When the blower 30 runs at the second speed for the preset time, the temperature of the burner 60 is high, the gas mixture of gas and air is fully preheated, and the combustion speed is increased. Therefore, at this time, the blower 30 is controlled to run at the first speed to provide the burner 60 with an air volume that matches the gas flow rate. The probability of flameout is low, and the burner 60 performs fully premixed combustion.

[0161] In this embodiment of the invention, the blower 30 operates at the second speed for the preset time and then switches to the first speed, thereby improving the ignition success rate, reducing the generation of harmful substances, and improving combustion efficiency.
