Technical Field

[0001] The present invention relates to the technical field of stoves, and in particular to a control method of a stove. Background Art

[0002] With the development of technology, the existing range hood and stove can be linked through a wireless module. When the stove is turned on, the wireless module of the stove sends the stove's turning on information to the wireless module of the range hood. The range hood is turned on and draws out oil smoke, which can save the user from turning on the range hood. Usually, the wireless module of the stove is controlled by the main control chip of the stove and sends information. In the existing stove, when the ignition switch knob performs the turning on operation, the main control chip is connected to the power supply circuit of the battery, and the stove's turning on information can be sent to the wireless module of the range hood through the stove's wireless module in a timed manner, and the range hood can respond to the stove in a timed manner. However, when the ignition switch knob performs the turning off operation, the main control chip is disconnected from the battery's power supply circuit, and the main control chip cannot transmit the stove's information to the wireless module of the range hood through the stove's wireless module in time. The range hood will lose contact with the stove signal, and the range hood cannot respond to the stove's turning off information in time. Summary of the invention

[0004] A control method for a stove, the stove comprises a battery, an ignition switch knob, an ignition pulse module, a main control chip, a power supply control module, a wireless module and a valve control module. A user performs an ignition operation or an ignition operation through the ignition switch knob so that the battery supplies power to or cuts off the power to the main control chip. The control method for the stove comprises: after the user performs the ignition operation through the ignition switch knob, the battery, the power supply control module and the main control chip circuit are connected, the power supply control module stores a part of the electric energy while boosting the voltage output by the battery and transmitting it to the main control chip, the main control chip turns on the power supply of the ignition pulse module and sends an ignition instruction at the same time, so that the valve control module controls the gas valve to be opened, At the same time, the ignition pulse module is started, and the stove begins to ignite. After the stove finishes igniting, the main control chip turns off the power supply of the ignition pulse module, the ignition pulse module is turned off, the stove ignites normally, and the main control chip sends the stove status information to other devices through the wireless module; after the user performs the fire-off operation through the ignition switch knob, the connection circuit between the battery and the power supply control module is disconnected, and the power supply control module supplies power to the main control chip through the stored electric energy, so that the main control chip delays power off. During the time of delayed power off of the main control chip, the main control chip controls the closing of the gas valve through the valve control module, the stove is turned off, and the main control chip sends the stove status information to other devices through the wireless module.

[0005] According to one embodiment of the present invention, the discharge time of the electric energy stored in the power supply control module is t1, the delay time of the power-off of the main control chip is t2, t1≥t2, and after the main control chip sends the stove status information to other devices through the wireless module, the power supply control module cuts off the power of the main control chip.

[0006] According to one embodiment of the present invention, the stove is further provided with a battery power detection module. After the user performs the ignition operation by turning the ignition switch knob, the battery, the power supply control module and the main control chip circuit are connected. The power detection module detects the battery power and sends the detection result to the main control chip. When the power detection module detects that the battery power V>V1, the main control chip turns on the power supply of the ignition pulse module and sends an ignition instruction at the same time, so that the valve control module controls the gas valve to open, and at the same time, the ignition pulse module of the stove is started, and the stove starts to ignite. After the stove completes the ignition, the main control chip turns off the power supply of the ignition pulse module, the ignition pulse module is turned off, and the stove ignites normally; when the power detection module detects that the battery power V≤V1, the main control chip does not turn on the power supply of the ignition pulse module, does not send the ignition instruction, the stove fails to ignite, the connection circuit between the battery and the power supply control module is disconnected, the power supply control module supplies power to the main control chip, so that the main control chip delays power off, and the main control chip sends information such as the stove status and battery power to other devices through the wireless module, wherein V1 is the minimum power at which the stove can ignite normally.

[0007] According to one embodiment of the present invention, the main control chip is provided with a timing module and a voltage detection module, the valve control module includes a solenoid valve and a thermocouple, when the battery powers the main control chip, the solenoid valve is connected to the circuit and accepts the instruction of the main control chip to open or close the gas valve, the voltage detection module is used to detect the voltage across the thermocouple, after the stove is normally ignited, the main control chip enters a dormant state, the battery power detection module, the wireless module and the voltage detection module are dormant, the circuit connecting the solenoid valve and the battery is disconnected, the thermocouple is heated to generate electrical energy to power the solenoid valve, the timing module starts timing, and the main control chip is awakened at every interval T, and the voltage detection module and the battery power detection module are used to detect whether the ignition state of the stove and the battery power state have changed. If there is no change, the main control chip enters a dormant state again, the battery power detection module, the wireless module and the voltage detection module are dormant, and the timing module restarts timing.

[0008] According to one embodiment of the present invention, if the timing module counts T, the main control chip is awakened, and if the battery power detection module detects that the battery power V≤V1, the wireless module is awakened, the main control chip sends a fire-off command, the valve control module controls the gas valve to close, and the main control chip sends the battery power status information to other devices through the wireless module, and continuously reminds the user that the battery is low.

[0009] According to one embodiment of the present invention, the stove is also provided with an ignition switch knob detection module. If the timing module times T, the main control chip is awakened. If the voltage value detected by the voltage detection module at both ends of the thermocouple is 0, and the ignition switch knob detection module detects that the ignition switch knob is in the ignition state, the main control chip determines that the valve control module has closed the gas valve and the stove is turned off. The main control chip wakes up the wireless module and sends data on the ignition state of the stove to other devices through the wireless module and reminds the user to reset the switch knob.

[0010] According to one embodiment of the present invention, the stove also includes a gear detection module. When the stove is normally ignited, if the user adjusts the fire power gear of the stove through the ignition switch knob, the gear detection module detects the fire power gear of the stove in real time and sends the detection result to the main control chip. The main control chip sends the fire power gear information of the stove to other devices through the wireless module.

[0011] According to one embodiment of the present invention, after the stove is normally started, the main control chip enters a sleep state, the wireless module goes into sleep mode, and the gear detection module detects the fire power gear of the stove in real time. When the gear detection module detects that the fire power gear of the stove has changed, the main control chip is awakened, and the gear detection module sends the detection result to the main control chip. The main control chip sends the fire power gear information of the stove to other devices through the wireless module. After the fire power gear information is sent, the main control chip and the wireless module go into sleep mode again.

[0012] According to one embodiment of the present invention, the main control chip is also provided with a timing module. After the stove is normally ignited, the main control chip enters a sleep state, the battery power detection module and the wireless module are in sleep state, and the gear detection module and the timing module are running. The battery power detection module detects whether the battery power status satisfies V>V1 every time T. If so, the battery power detection module continues to sleep. If not, the wireless module and the main control chip are awakened, the main control chip sends a fire-off instruction, the valve control module controls the gas valve to close, and the connection circuit between the battery and the power supply control module is disconnected. The power supply control module supplies power to the main control chip through the stored electric energy. During the time when the main control chip is delayed to be powered off, the main control chip sends the stove status information to other devices through the wireless module; during the timing of the timing module, the gear detection module detects the stove firepower gear in real time.

[0013] According to one embodiment of the present invention, when the number of burners of the stove is greater than one, each burner has a corresponding ignition switch knob, a valve control module and an ignition pulse module. When any ignition switch knob performs an ignition operation, the battery, the power supply control module and the main control chip circuit are connected, the main control chip turns on the power supply of the ignition pulse module and sends an ignition instruction at the same time, so that the valve control module controls the corresponding gas valve to open, and at the same time starts the corresponding ignition pulse module to complete the ignition of the stove; when any ignition switch knob performs an off-fire operation, the main control chip will cause the corresponding valve control module to control the corresponding gas valve to close; when all ignition switch knobs perform an off-fire operation, the battery cuts off power to the main control chip, the power supply control module supplies power to the main control chip, delays power off of the main control chip, and the main control chip controls the closing of the gas valve through the valve control module, the stove is turned off, and the main control chip sends the stove status information to other devices through the wireless module.

[0014] Compared with the prior art, the control method of the stove of the present invention has the following advantages:

[0015] The control method of the stove of the present invention is that after the user performs the fire-off operation through the ignition switch knob, when the battery is disconnected from the main control chip circuit, the main control chip is powered by the power supply control module, so that the main control chip has time to send the status information of the stove to other devices through the wireless module, thereby avoiding the signal loss between other devices and the stove.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0022] See also Figure 1The present invention discloses a control method for a stove. The stove includes a battery, an ignition switch knob, an ignition pulse module, a main control chip, a power supply control module, a wireless module and a valve control module. A user performs an ignition operation or an ignition operation through the ignition switch knob so that the battery supplies power to or cuts off the power of the main control chip. The control method for the stove is as follows: after the user performs an ignition operation through the ignition switch knob, the battery, the power supply control module and the main control chip circuit are connected. The power supply control module stores a part of the electric energy while boosting the voltage output by the battery and transmitting it to the main control chip. The main control chip sends an ignition instruction while turning on the power supply of the ignition pulse module, so that the valve control module controls the gas valve The main control chip is turned on, and the ignition pulse module is started at the same time, and the stove starts to ignite. After the stove finishes ignition, the main control chip turns off the power supply of the ignition pulse module, the ignition pulse module is turned off, the stove ignites normally, and the main control chip sends the stove status information to other devices through the wireless module; after the user performs the fire-off operation through the ignition switch knob, the connection circuit between the battery and the power supply control module is disconnected, and the power supply control module supplies power to the main control chip through the stored electric energy, so that the main control chip delays power off. During the time of the main control chip delaying power off, the main control chip controls the closing of the gas valve through the valve control module, and the stove turns off, and the main control chip sends the stove status information to other devices through the wireless module. In the control method of the stove of the present invention, the power supply control module is connected between the battery of the stove and the main control chip, and the power supply control module can not only increase the low voltage output by the battery to a voltage suitable for the main control chip, but also store a part of the electric energy when the battery and the main control chip circuit are connected. After the user performs the ignition operation by turning the ignition switch knob, the battery, power supply control module and main control chip circuits are connected, the power supply outputs a voltage of 0.3V-6V, the power supply control module converts the voltage output by the battery into a voltage of 3.3V and distributes it to the main control chip, so that the main control chip is powered on. At the same time, the power supply control module starts to charge and store part of the electrical energy.After the main control chip is powered on, the main control chip turns on the power supply of the ignition pulse module and sends an ignition command at the same time. Under the control of the ignition command, the valve control module controls the gas valve to open and the ignition pulse module to start. After the stove is ignited, the main control chip turns off the power supply of the ignition pulse module, the ignition pulse module is turned off, and the stove is ignited normally. After the user performs the fire-off operation through the ignition switch knob, the battery is disconnected from the circuit of the main control chip, and the power supply module uses its stored electric energy to power the main control chip, so that the main control chip delays power off. During the time when the main control chip delays power off, the main control chip controls the closing of the gas valve through the valve control module to turn off the stove, and then sends the stove status information to other devices through the wireless module. The other devices here can be an APP installed on the user's mobile phone, or a wireless module of a range hood linked to the stove. After the wireless module of the range hood receives the status information of the stove sent by the wireless module of the stove, the range hood can adjust its own status according to the status information of the stove, such as shutting down in time or delaying shutdown.

[0023] The control method of the stove of the present invention is that after the user performs the fire-off operation through the ignition switch knob, when the battery is disconnected from the main control chip circuit, the main control chip is powered by the power supply control module, so that the main control chip has time to send the status information of the stove to other devices through the wireless module, thereby avoiding the signal loss between other devices and the stove.

[0024] In the control method of the stove of the present invention, the discharge time of the electric energy stored in the power supply control module is t1, the delay time of the power off of the main control chip is t2, t1≥t2, and after the main control chip sends the stove status information to other devices through the wireless module, the power supply control module cuts off the power of the main control chip. The method to avoid the loss of signal connection between the stove and other devices is to make the main control chip of the stove send the status information of the stove through the wireless module before cutting off the power. The delay power off time t2 of the main control chip is the shortest time required for the main control chip to send the status information of the stove through the wireless module, and the discharge time of the electric energy stored in the power supply control module is t1, which is the time that the power supply control module can maintain the main control chip without powering off. Only when t1≥t2, the main control chip has enough time to send the status information of the stove through the wireless module. In the case of t1>t2, the main control chip has sent the status information of the stove through the wireless module and the electric energy stored in the power supply control module has not been released. At this time, the power supply control module can actively cut off the power of the main control chip. The signal that the power supply control module actively cuts off the power to the main control chip may come from a return signal from other devices. For example, after the range hood receives the signal sent by the wireless module of the stove, the signal is returned through the wireless module of the range hood and the wireless module of the stove receives it, and then the power supply control module cuts off the power to the main control chip.

[0025] The control method of the stove of the present invention is that the stove is also provided with a battery power detection module. After the user performs the ignition operation by turning the ignition switch knob, the battery, the power supply control module and the main control chip circuit are connected. The power detection module detects the battery power and sends the detection result to the main control chip. When the power detection module detects that the battery power V>V1, the main control chip turns on the power supply of the ignition pulse module and sends an ignition instruction at the same time, so that the valve control module controls the gas valve to open, and the ignition pulse module of the stove is started at the same time, and the stove starts to ignite. After the stove completes the ignition, the main control chip turns off the power supply of the ignition pulse module, the ignition pulse module is turned off, and the stove is normally ignited; when the power detection module detects that the battery power V≤V1, the main control chip does not turn on the power supply of the ignition pulse module, does not send the ignition instruction, the stove fails to ignite, the connection circuit between the battery and the power supply control module is disconnected, the power supply control module supplies power to the main control chip, so that the main control chip delays power off, and the main control chip sends information such as the stove state and the battery power to other devices through the wireless module, wherein V1 is the minimum power that the stove can normally ignite. The control method of the stove of the present invention is that after the user performs the ignition operation through the ignition switch knob, the main control chip is connected to the circuit, and the battery power detection module first detects the battery power V. Only when the battery power is greater than the minimum power that the stove can normally ignite, the main control chip will turn on the power supply of the ignition pulse module, and then send an ignition signal to make the valve control module control the gas valve to open, so that the ignition pulse module starts to ignite. After the ignition is completed, the ignition pulse module is turned off. After the user performs the ignition operation through the ignition switch knob, the main control chip is connected to the circuit, and the battery power detection module detects that the battery power V≤V1, which means that the battery power is not higher than the minimum power that the stove can normally ignite. If the stove is turned on at this time, the battery power will be fully released during the normal operation of the stove. When the battery power is fully released, the circuit connection between the battery and the main control chip is disconnected, and the ignition switch knob does not perform the ignition off operation. The main control chip will exhaust the power stored in the power supply control module and then cut off the power, and the main control chip will not have time to turn off the valve control module. Closing the gas valve will make it impossible to turn off the stove. Therefore, when the main control chip is connected to the circuit and the battery power detection module detects that the battery power V≤V1, the main control chip does not turn on the power supply of the ignition pulse module and does not send an ignition command. The stove fails to start, and the connection circuit between the battery and the power supply control module is disconnected. The power supply control module supplies power to the main control chip, delaying the power off of the main control chip. The main control chip sends information such as the stove status and battery power to other devices through the wireless module. When the other device is a range hood, the range hood will not start after receiving the signal.

[0026] See also Figure 1In the control method of the stove of the present invention, the main control chip is provided with a timing module and a voltage detection module, the valve control module includes a solenoid valve and a thermocouple, when the battery supplies power to the main control chip, the solenoid valve is connected to the circuit and receives the instruction of the main control chip to open or close the gas valve, the voltage detection module is used to detect the voltage at both ends of the thermocouple, after the stove is normally fired, the main control chip enters a dormant state, the battery power detection module, the wireless module and the voltage detection module are dormant, the circuit connecting the solenoid valve and the battery is disconnected, the thermocouple is heated to generate electricity to power the solenoid valve, the timing module starts timing, every interval time T, the main control chip is awakened, and the voltage detection module and the battery power detection module are used to detect whether the firing state of the stove and the battery power state have changed, if there is no change, the main control chip enters a dormant state again, the battery power detection module, the wireless module and the voltage detection module are dormant, and the timing module restarts timing. It is easy to know that after the stove is normally started, there is a temperature gradient at both ends of the thermocouple, and there is a thermoelectric potential between the two ends of the thermocouple. Current will flow through the loop formed by the thermocouple and the electromagnetic valve, and the thermocouple can convert thermal energy into electrical energy to keep the electromagnetic valve in the state of opening the gas valve. In order to save battery power, reduce battery power consumption, and extend battery life, the control method of the stove of the present invention is that after the stove is normally started, the circuit connecting the electromagnetic valve and the battery is disconnected, and the thermocouple is heated to generate electrical energy to power the electromagnetic valve. If the stove is accidentally extinguished in the middle of burning, the temperature gradient at both ends of the thermocouple gradually disappears, and after the voltage generated by the thermocouple disappears or is insufficient to keep the electromagnetic valve in the state of opening the gas valve, the electromagnetic valve will close the gas valve to avoid danger caused by gas leakage. In order to further reduce the power consumption of the battery, after the stove is normally ignited, the main control chip enters a dormant state, the battery power detection module, the wireless module and the voltage detection module are dormant, the circuit connecting the solenoid valve and the battery is disconnected, the thermocouple is heated to generate electricity to power the solenoid valve, and the timing module starts timing. At each interval T, the main control chip is awakened, and the voltage detection module and the battery power detection module are used to detect whether the stove's ignition status and the battery's power status have changed. If the stove is accidentally extinguished during the dormant time T of the main control chip, the voltage across the thermocouple will decrease or become 0. When the main control chip is awakened, the voltage detection module can determine whether the circuit composed of the thermocouple and the solenoid valve is disconnected by detecting the voltage across the thermocouple. If it is disconnected, it indicates that the stove is extinguished and the stove's ignition status has changed. The wireless module will be awakened, and the main control chip will send the data of the stove's ignition status to other devices through the wireless module. When the other device is a range hood, after the wireless module of the range hood receives the stove's ignition status information, the range hood will be shut down or shut down after a set delay.Or / and if the battery power drops to V≤V1 during the sleep time T of the main control chip, when the main control chip is awakened, the battery power detection module detects that the battery power drops to V≤V1, the wireless module will be awakened, and the main control chip will send the battery power status data to other devices through the wireless module. If the battery power always satisfies V>V1 during the sleep time T of the main control chip, and the stove is not accidentally turned off, when the main control chip is awakened, the voltage detection module detects that the voltage across the thermocouple is normal, and the battery power detection module detects that the battery power is positive, the main control chip enters the sleep state again, the battery power detection module, the wireless module and the voltage detection module sleep, and the timing module restarts timing.

[0027] The control method of the stove of the present invention is as follows: if the wireless module is awakened after the timing module counts T, and if the battery power detection module detects that the battery power V≤V1, the wireless module is awakened, the main control chip sends a fire-off instruction, the valve control module controls the gas valve to close, and the main control chip sends the battery power status information to other devices through the wireless module, and continuously reminds the user that the battery power is low. If the battery power drops to V≤V1 within the time T when the main control chip is dormant, and after the main control chip is awakened, the battery power status is detected by the battery power detection module, and then the wireless module is awakened, the main control chip sends a fire-off instruction, the valve control module controls the gas valve to close, and the main control chip sends the battery power status information to other devices through the wireless module, so that other devices adjust their own states according to the fire-off state of the stove, and at the same time, the main control chip continuously reminds the user that the battery power is low, so that the user resets the ignition switch knob.

[0028] The control method of the stove of the present invention is that the stove is also provided with an ignition switch knob detection module. If the timing module counts T, the main control chip is awakened. If the voltage value detected by the voltage detection module at both ends of the thermocouple is 0, and the ignition switch knob detection module detects that the ignition switch knob is in the firing state, the main control chip determines that the valve control module has closed the gas valve, and the stove is turned off. The main control chip wakes up the wireless module and sends the firing state of the stove to other devices through the wireless module and reminds the user to reset the switch knob. The situation that the stove is accidentally turned off and the user sends the fire to turn off can be judged by the ignition switch knob detection module. When the stove is accidentally turned off, the valve control module closes the gas valve, but the position of the ignition switch knob is still in the firing state. However, if the user turns off the fire through the ignition switch knob, the position of the ignition switch knob is in the off state. When the main control chip is dormant, if the user actively turns off the fire, the battery is disconnected from the circuit of the main control chip, and the power supply control module supplies power to the main control chip. At the end of a timing cycle, if the ignition switch knob detection module detects that the ignition switch knob is in the off state, the main control chip sends the status information of the stove through the wireless module, and the power supply control module cuts off the power of the main control chip, and the stove enters a completely power-off state; however, if the stove accidentally goes out within a timing cycle, at the end of a timing cycle, the voltage detection module detects that the voltage value at both ends of the thermocouple is 0, and the ignition switch knob detection module detects that the ignition switch knob is in the on state, then the main control chip determines that the valve control module has closed the gas valve, and the stove goes out, the main control chip wakes up the wireless module and sends the data of the stove's on state to other devices through the wireless module and reminds the user to reset the switch knob.

[0029] In other embodiments, the stove further includes a gear detection module. When the stove is normally ignited, if the user adjusts the stove power gear through the ignition switch knob, the gear detection module detects the stove power gear in real time and sends the detection result to the main control chip, and the main control chip sends the stove power gear information to other devices through the wireless module. In the stove control method of the present invention, the stove can be linked with other devices, for example, the stove can be linked with the range hood in real time. When the stove power gear changes, the gear detection module can detect the change of the firepower and send the detected firepower change to the main control chip, the main control chip sends the stove power change to the range hood through the wireless module, and the range hood can adjust the air volume gear according to the stove power gear.

[0030] In an embodiment of a control method for a stove with a gear detection module, after the stove is normally fired, the main control chip enters a dormant state, the wireless module is dormant, and the gear detection module detects the stove's firepower gear in real time. When the gear detection module detects that the stove's firepower gear has changed, the main control chip is awakened, and the gear detection module sends the detection result to the main control chip. The main control chip sends the stove's firepower gear information to other devices through the wireless module. After the firepower gear information is sent, the main control chip and the wireless module go into sleep again. When the main control chip is dormant, the gear detection module detects the stove's firepower gear in real time. As long as the gear detection module detects that the stove's firepower gear has changed, the main control chip will be awakened and the firepower gear change information will be sent to the range hood through the wireless module, so that the range hood can adjust the air volume gear at any time according to the firepower change. The gear detection module is set, and when the stove is normally fired, the main control chip can go into sleep mode to avoid wasting battery power consumption. At the same time, the gear detection module monitors the firepower in real time to prevent the main control chip from missing changes in the range hood status information.

[0031] In an embodiment of a control method for a stove with a gear detection module, a main control chip is provided with a timing module. After the stove is normally ignited, the main control chip enters a sleep state, the battery power detection module and the wireless module are in sleep state, and the gear detection module and the timing module are running. The battery power detection module detects whether the battery power state satisfies V>V1 every time T. If so, the battery power detection module continues to sleep. If not, the wireless module and the main control chip are awakened, the main control chip sends a fire-off instruction, the valve control module controls the gas valve to close, the connection circuit between the battery and the power supply control module is disconnected, and the power supply control module supplies power to the main control chip through the stored electric energy. During the time when the main control chip is delayed to be powered off, the main control chip sends the stove status information to other devices through the wireless module; during the timing of the timing module, the gear detection module detects the stove firepower gear in real time. The control method of the main control chip according to the battery power status is the same as that in the above embodiment and will not be repeated here. The difference is that in this embodiment, due to the existence of the gear detection module, during the timing of the timing module, the gear detection module detects the fire power gear of the stove in real time, which can avoid missing the change of the range hood status information when the main control chip is in sleep mode.
