[0042] In order to make the purpose, technical solution and advantages of the present application more clear and understandable, the technical solutions in the embodiments of the present application will be further described in detail through the following embodiments in combination with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the drawings.

[0043] Generally, a gas stove realizes the firepower adjustment between the inner ring and the outer ring through the flame conduction of the fire transfer seam. However, limited by factors such as insufficient external pressure and cookware, when the firepower of the gas stove is transferred from the inner ring to the outer ring, technical problems such as poor fire transfer often occur, such as unsuccessful fire transfer or slow fire transfer speed. For example, for a gas stove with three-ring fire or five-ring fire, after the inner ring is successfully ignited, when the firepower is increased, problems such as slow fire transfer speed or unsuccessful fire transfer from the inner ring to the middle ring often occur, affecting the user experience.

[0044] Therefore, the technical solution provided by the embodiments of the present application, when detecting that the firepower of the gas stove changes from the inner ring to the outer ring, controls the middle ring ignition device to ignite again. Through the key ignition method, the transfer of the inner ring fire to the outer ring fire can be quickly realized, effectively avoiding the situation of unsuccessful fire transfer or slow fire transfer speed, and meeting the cooking needs of users.

[0045] Figure 1 It is a schematic flowchart of a control method for a gas stove provided by an embodiment of the present application. As Figure 1 shown, the method may include:

[0046] S101. When the gas stove is in the firing state, detect the current firepower change trend of the gas stove.

[0047] S102. When the firepower change trend is from the inner ring to the outer ring, ignite the middle ring ignition device of the gas stove.

[0048] Specifically, in one implementation, when the user uses the gas stove, the user turns on the firepower adjustment knob. The gas stove triggers the corresponding ignition device to generate continuous instantaneous electric sparks according to the user's ignition instruction, and controls the gas path to open to realize the ignition of the gas stove. After the ignition is successful, the gas stove is in the firing state.

[0049] In an optional implementation, the ignition device used when the gas stove is turned on can be the middle ring ignition device, that is, the gas stove can only include the middle ring ignition device, and the middle ring ignition device is used to simultaneously realize the ignition of the gas stove when it is turned on and the quick fire transfer when the inner ring fire is transferred to the outer ring fire.

[0050] As another alternative implementation, the gas stove may further include an inner-ring ignition device. The gas stove is ignited through the inner-ring ignition device, and the rapid fire transfer from the inner-ring flame to the outer-ring flame is achieved through the middle-ring ignition device. The embodiments of the present application do not limit the ignition device for igniting the gas stove at the start.

[0051] As an alternative implementation, the gas stove may further include a potentiometer and a firepower adjustment knob, and the potentiometer is connected to the firepower adjustment knob. Optionally, the ignition process of the above gas stove may include: when it is detected through the potentiometer that the firepower adjustment knob starts to rotate away from the initial position, the inner-ring ignition device / middle-ring ignition device of the gas stove is ignited.

[0052] Among them, since the potentiometer is connected to the firepower adjustment knob, when the firepower adjustment knob is in the initial position, the gas stove is in the off-fire state. At this time, the potentiometer outputs a first voltage signal. When the firepower adjustment knob rotates away from the initial position, the potentiometer outputs a second voltage signal. In this way, when the first voltage signal and the second voltage signal output by the potentiometer are received, it can be detected that the firepower adjustment knob starts from the initial position and rotates away from the initial position, and then the inner-ring ignition device / middle-ring ignition device of the gas stove can be ignited.

[0053] Optionally, in order to improve the ignition success rate, an inner-ring ignition device, such as an inner-ring ignition needle, may be provided at the fire hole position of the inner-ring burner cap of the gas stove. When it is detected through the potentiometer that the firepower adjustment knob starts to rotate away from the initial position, the inner-ring ignition device of the gas stove is ignited.

[0054] In this way, only by rotating the firepower adjustment knob can the ignition of the gas stove be achieved. The operation is simple, and at the same time, the ignition of the inner-ring ignition device can further improve the ignition success rate of the gas stove.

[0055] Optionally, the above middle-ring ignition device may include a middle-ring ignition needle, and the middle-ring ignition needle may be arranged at the inner fire hole position or the outer fire hole position of the middle-ring burner cap to facilitate the rapid ignition of the middle-ring fire holes.

[0056] In an alternative implementation, the above gas stove may include a thermocouple. One end (cold end) of the thermocouple is connected to the controller (or processor) of the gas stove, and the other end (working end) of the thermocouple is arranged beside the fire hole of the inner-ring burner cap to sense the flame temperature.

[0057] Optionally, the process of determining that the gas stove is in the on-fire state may include: obtaining the thermoelectromotive force of the thermocouple, and determining that the gas stove is in the on-fire state when the thermoelectromotive force is greater than a first preset threshold.

[0058] Specifically, a thermocouple can be used to convert the temperature signal of a flame into a thermoelectromotive force signal. The controller of the gas stove can be used to detect the thermoelectromotive force signal and obtain the thermoelectromotive force of the thermocouple. When it is determined that the thermoelectromotive force is greater than the first preset threshold, it is determined that the gas stove is in the firing state. Optionally, the first preset threshold can be 0 or other values, not limited to 0. For example, the first preset threshold is within a small range greater than 0.

[0059] Optionally, the above gas stove may further include a multi-ring burner (such as a burner providing two-ring fire, three-ring fire or five-ring fire). Taking the burner providing five-ring fire as an example, through the multi-ring burner, various flame forms can be provided, such as Figure 2 As shown, for example, the flame forms may include the maximum fire of the five-ring fire, the medium fire of the five-ring fire, the medium-small fire of the five-ring fire, the minimum fire of the five-ring fire, the minimum fire of the multi-ring fire (i.e., the three-ring fire), and the inner-ring fire. The inner-ring fire can also be divided into two gears, the minimum fire of the inner-ring fire and the maximum fire of the inner-ring fire. The firepower change trend can be the transition between any two of the above flame forms.

[0060] Therefore, when the gas stove is in the firing state, the current firepower change trend of the gas stove is detected in real time. In an optional implementation manner, the above gas stove may include an image acquisition device, which can collect the images generated during the process of the user adjusting the firepower in real time through the image acquisition device, perform image processing on the images, extract the feature data in the images through a pre-trained network, and determine the current firepower change trend of the gas stove based on the feature data.

[0061] When it is detected that the current firepower change trend of the gas stove is from the inner ring to the outer ring (for example, when changing from Figure 2 the maximum fire of the middle inner-ring fire to the minimum fire of the multi-ring fire. Here, the minimum fire of the multi-ring fire can be the minimum fire of the three-ring fire or the minimum fire of the five-ring fire, or even the minimum fire of more rings), the gas stove is controlled to supply power to the middle-ring ignition device. The middle-ring ignition device discharges to ignite the gas ejected from the middle-ring burner cap, and ignite the middle-ring fire holes, so as to realize the rapid transition from the inner-ring fire to the outer-ring fire, accelerate the conduction of the flame, and avoid the problem of poor fire transfer, ensuring the success of fire transfer.

[0062] In this embodiment, when the gas stove is in the firing state, the current firepower change trend of the gas stove is detected. When it is determined that the current firepower change trend of the gas stove is from the inner ring to the outer ring, the middle-ring ignition device of the gas stove is ignited. By focusing on igniting the middle-ring ignition device of the gas stove, the middle-ring fire holes can be quickly ignited. Compared with the method of simply igniting the middle-ring fire holes through the fire transfer seam, the fire transfer speed and the fire transfer success rate are greatly improved, thus solving the technical problem of poor fire transfer when the firepower of the gas stove is transferred from the inner ring to the outer ring.

[0063] In an alternative implementation, detecting the current firepower change trend of the gas stove may include:

[0064] Detecting the angular change of the firepower adjustment knob rotation through a potentiometer; determining the current firepower change trend of the gas stove based on the angular change of the firepower adjustment knob rotation.

[0065] Specifically, since the potentiometer is connected to the firepower adjustment knob, when the firepower adjustment knob is rotated under an external force, the firepower adjustment knob can drive the potentiometer to rotate, thereby changing the resistance value of the potentiometer. Furthermore, the angular change of the firepower adjustment knob deviating from the initial position is detected through the change of the internal resistance value of the potentiometer, and then the current firepower change trend of the gas stove is determined based on the angular change of the firepower adjustment knob rotation. Optionally, the current firepower change trend of the gas stove can be determined based on the angular change of the firepower adjustment knob rotation and a preset firepower change mapping relationship. Among them, the above-mentioned firepower change mapping relationship may include the corresponding relationship between different angular changes and firepower change trends.

[0066] Continuing with Figure 2 the firepower change mapping relationship shown as an example, assuming that the initial position of the firepower adjustment knob (i.e., the off state of the gas stove) is 0 degrees, when the firepower adjustment knob deviates from the initial position and rotates to 210°, the corresponding flame form of the gas stove is the smallest fire of the multi-ring fire. When the firepower adjustment knob deviates from the initial position and rotates to 240°, the corresponding flame form of the gas stove is the largest fire of the inner ring fire. If it is detected by the potentiometer that the firepower adjustment knob rotates from 240° to 210°, it can be determined that the firepower of the gas stove changes from the inner ring fire to the outer ring fire (such as changing to the smallest fire of the multi-ring fire). At this time, the middle ring ignition device can be directly ignited, so as to quickly ignite the middle ring fire holes and realize the transfer of the flame.

[0067] In this embodiment, the angular change of the firepower adjustment knob rotation is detected through a potentiometer, and the current firepower change trend of the gas stove is determined based on the angular change of the firepower adjustment knob rotation. When the firepower adjustment knob is rotated, the internal mechanical structure of the potentiometer rotates accordingly, thereby realizing the accurate detection of the firepower change trend through the signal of the potentiometer, and further improving the fire transfer speed and the fire transfer success rate.

[0068] In some embodiments, the gas stove may further include a gas valve, and when the gas stove is in the firing state, the gas valve is in the ventilation state. Refer to Figure 3 and the method further includes:

[0069] S103. When the thermoelectric potential of the thermocouple drops to a first preset threshold, control the gas valve to switch from the ventilation state to the gas cut-off state.

[0070] Specifically, when the gas valve is in the gas-on state, the gas path of the gas stove is opened. When the gas stove is in the gas-off state, the gas path of the gas stove is disconnected. When the gas valve is in the gas-on state, the opening degree of the gas valve can be further adjusted to control the firepower of the burner.

[0071] On the one hand, the user opens the firepower adjustment knob to make the gas valve in the gas-on state to open the gas path, thereby providing the firing condition of the gas stove. On the other hand, when the gas stove is in the firing state, the thermoelectric potential of the thermocouple is detected in real time. If the thermoelectric potential of the thermocouple drops to the first preset threshold, the controller can control the gas valve to switch from the gas-on state to the gas-off state, disconnect the gas path, and make the gas stove switch from the firing state to the extinguished state, avoiding gas output after the flameout.

[0072] In this way, gas leakage can be avoided and the safe use of the gas stove can be protected.

[0073] In some embodiments, optionally, refer to Figure 4 and the method further includes:

[0074] S104. When the thermoelectric potential of the thermocouple rises to the second preset threshold, timing is performed.

[0075] S105. When the timing duration reaches the preset duration, control the gas valve to switch from the gas-on state to the gas-off state, and send a wind volume adjustment message to the range hood; wherein, the wind volume adjustment message is used to control the range hood to increase the wind volume.

[0076] On the one hand, the user opens the firepower adjustment knob to make the gas valve in the gas-on state to open the gas path, thereby providing the firing condition of the gas stove. On the other hand, when the gas stove is in the firing state, the thermoelectric potential of the thermocouple is detected in real time. If the thermoelectric potential of the thermocouple rises to the second preset threshold, timing is performed. When the timing duration reaches the preset duration, control the gas valve to switch from the gas-on state to the gas-off state, disconnect the gas path, and make the gas stove switch from the firing state to the extinguished state. Therefore, the automatic extinguishing protection of the gas stove can be realized in a low-cost way without adding hardware such as anti-dry burning.

[0077] Furthermore, the gas stove can also be interconnected with the range hood. While controlling the gas stove to turn off automatically at a fixed time, a wind volume adjustment message for increasing the wind volume can also be sent to the range hood, so that the range hood increases the working wind volume, and excessive oil fumes caused by too long food cooking time can be discharged in time.

[0078] The above-mentioned second preset threshold is greater than the first preset threshold, and the above-mentioned second preset threshold can be calibrated and stored in advance. The above-mentioned preset duration can also be set according to actual needs. For example, the preset duration can be 2 hours, and this embodiment does not limit this.

[0079] In this way, it is possible to avoid the situation where the user forgets to turn off the fire after cooking the food for too long, and protect the safe use of the gas stove.
