Example 1, see Figure 1 , Figure 1 Schematic diagram of a gas stove according to an embodiment of the present invention. Figure 1 As shown, the gas stove includes a manual-automatic valve 1 and a main controller 2.

[0027] The manual-automatic valve 1 includes a multifunctional plug 10, a micro switch 11 and a connecting rod mechanism 12, wherein the multifunctional plug 10 includes an intelligent control knob 100, a rotary encoder 101 installed inside the intelligent control knob 100, and a manual knob 102 installed below the intelligent control knob 100, and the micro switch 11 and the connecting rod mechanism 12 are installed below the manual knob 102.

[0028] like Figure 2 As shown, Figure 2 It is a structural schematic diagram of another embodiment of a gas stove provided in the present application.

[0029] In one embodiment, the gas stove provided in the present application further includes: a manual stopcock valve 3.

[0030] Specifically, the manual stopcock valve 3 is used to manually rotate to select a firepower gear and control the firepower size based on the firepower gear.

[0031] Specifically, the manual stopcock valve 3 retains all the functions of the manual stopcock gas stove. When the power is low and the intelligent function is limited, the user can use the manual function normally, giving the user sufficient time to replace the battery, avoiding the phenomenon that the gas stove cannot be used due to low battery power, thereby improving the user experience.

[0032] In one embodiment, the gas stove provided in the present application further includes: an air intake distribution pipe component 4.

[0033] Specifically, the air intake air distribution pipe component 4 is connected to the manual-automatic integrated valve 1 , the manual stopcock valve 3 and the main controller 2 respectively.

[0034] Specifically, the air intake pipe component 4 is responsible for transporting gas from the gas source to different components of the gas stove, ensuring that the gas can smoothly reach the burner of the gas stove; and through the air intake pipe component 4 connected to the main controller 2, the main controller 2 can control the flow of gas through the motor valve 15, and then control the firepower of the gas stove.

[0035] In one embodiment, the multifunctional cock 10 further includes a fixing plate 103 and a screw 104; Figure 3 As shown, Figure 3 It is a structural schematic diagram of an embodiment of the multifunctional tap provided in the present application.

[0036] Specifically, the fixing plate 103 is placed between the smart control knob 100 and the rotary encoder 101 , and the screws 104 are used to fix the fixing plate 103 on the rotary encoder 101 .

[0037] In one embodiment, the manual-automatic valve 1 further includes: a pulse igniter 13, a flameout solenoid valve 14 and a motor valve 15. Figure 4a As shown, Figure 4a is a schematic diagram of the structure of an embodiment of the manual-automatic integrated valve provided by the present application, such as Figure 4b As shown, Figure 4b It is a structural schematic diagram of another embodiment of the manual-automatic integrated valve provided in the present application.

[0038] Specifically, the micro switch 11 includes a first micro switch 110 and a second micro switch 111 , and the connecting rod mechanism 12 includes a first connecting rod mechanism 120 , a second connecting rod mechanism 121 and a valve core 122 .

[0039] Specifically, the first connecting rod mechanism 120 is connected to the second connecting rod mechanism 121, the second connecting rod mechanism 121 is connected to the valve core 122, the valve core 122 is connected to the motor valve 15, and the motor valve 15 is connected to the main controller 2; the first micro switch 110 is connected to the pulse igniter 13, and the second micro switch 111 is connected to the manual stopcock 3.

[0040] Specifically, the first connecting rod mechanism 120 is located above the second connecting rod mechanism 121 , the valve core 122 is located on the side of the second connecting rod mechanism 121 , and the valve core 122 rotates with the rotation of the second connecting rod 121 .

[0041] Specifically, the first micro switch 110 and the second micro switch 111 are respectively located on both sides of the first connecting rod mechanism 120, and when the first micro switch 110 and the second micro switch 111 are on both sides of the first connecting rod mechanism 120, their positions and heights are not corresponding.

[0042] Specifically, the first micro switch 110 and the second micro switch 111 are rotationally connected to the first connecting rod mechanism 120 respectively.

[0043] Specifically, when the manual stopcock is pressed down and rotated, the first connecting rod mechanism 120 is driven to rotate. During the rotation of the first connecting rod mechanism 120, the outer circumferential surface of the first connecting rod mechanism 120 is in contact and connected with the first micro switch 110, and triggers the first micro switch 110 to be in a closed state.

[0044] Specifically, when the manual stopcock is pressed down and rotated, the first connecting rod mechanism 120 is driven to rotate. When the manual stopcock 3 is manually rotated to the maximum fire state, the first connecting rod mechanism 120 is in contact with and connected to the second micro switch 111, and triggers the second micro switch 111 to be in a closed state.

[0045] In one embodiment, the rotary encoder 101 is connected to the main controller 2, and the main controller 2 is used to identify the pulse signal generated by the rotary encoder 101 due to the rotation of the intelligent control knob, and execute the firepower control corresponding to the target intelligent menu.

[0046] Specifically, a series of functions such as opening, selecting and setting the intelligent menu are controlled by rotating the intelligent control knob 100.

[0047] Specifically, since the rotary encoder 101 is installed on the smart control knob 100 to detect the rotational movement and position of the smart control knob 100, when the user rotates the smart control knob 100, the rotary encoder 101 can convert this mechanical rotation into an electrical signal, namely a pulse signal.

[0048] Specifically, when the smart control knob 100 is rotated, the rotary encoder 101 generates pulse signals, which are transmitted to the main controller 2 through the connecting line; the main controller 2 identifies these pulse signals to determine the rotation intention of the smart control knob 100, such as which smart menu is selected.

[0049] Specifically, once the main controller 2 recognizes the pulse signal transmitted by the rotary encoder 101, it will execute the corresponding target smart menu according to the content of the pulse signal; for example, if the user selects the "soup making" mode by rotating the smart control knob, the main controller 2 will start the preset "soup making" program.

[0050] Specifically, when the target smart menu is executed, the main controller 2 will adjust the gas flow rate by controlling the valve opening of the motor valve 15 according to the firepower requirements of the target smart menu, thereby achieving precise firepower control; this firepower control includes but is not limited to timed fire shutdown, constant temperature cooking or other preset cooking parameters.

[0051] Specifically, the smart menu includes but is not limited to fixed temperature, frying, pan-frying, noodle cooking, steaming, boiling, soup making and timing, etc. Figure 5 As shown, Figure 5 This is a schematic diagram of the interface of an intelligent menu in a gas stove provided in the present application. The intelligent menu is arranged on the outer circumference of a manual-automatic integrated valve 1. The intelligent menu adopts a knob-type intelligent menu automatic selection mode, which can realize timing setting and fixed temperature setting, greatly shortening the user's operation time.

[0052] In one embodiment, when the manual knob 102 is pressed and rotated, the manual ignition or manual ignition stop is controlled through the connecting rod mechanism 12 and the micro switch 11 .

[0053] Specifically, the user directly controls the gas supply and ignition of the gas stove by pressing down and rotating the manual knob 102 .

[0054] Specifically, when the manual knob 102 is pressed down, it transmits the downward pressing and rotating force through the first connecting rod mechanism 120 and the second connecting rod mechanism 121, thereby driving the valve core 122 to rotate, thereby realizing manual adjustment of the valve opening of the motor valve 15, that is, opening or closing the gas supply; and the flameout solenoid valve 14 is manually opened by being pressed by the first connecting rod mechanism 120.

[0055] Specifically, the micro switch 11 is closed when the manual knob 102 is pressed down, and at the same time as the first micro switch 110 is closed, the main controller 2 simultaneously energizes the flameout solenoid valve 14 to keep the flameout solenoid valve 14 in an open valve state, and this action will also trigger the pulse igniter 13 to start ignition; the closure of the first micro switch 110 connects the circuit of the pulse igniter 13, so that the pulse igniter 13 can generate sparks and ignite the gas.

[0056] Specifically, when the manual knob 102 is pressed down, it first acts on the first micro switch 110, causing the first micro switch 110 to close, and starting the pulse igniter to perform the ignition operation; at the same time, the first connecting rod mechanism 120 and the second connecting rod mechanism 121 rotate due to the downward and rotating action of the manual knob 102, and then open the flameout solenoid valve 14, keep it in the energized state, and ensure the stability of the gas flow; at this time, the gas is ignited to ensure the normal operation of the stove.

[0057] Specifically, when the user releases the manual knob 102, that is, the manual knob 102 is not pressed down and rotated, the connecting rod mechanism 12 will reset, thereby causing the flameout solenoid valve to close, and the valve of the motor valve 15 to be closed. At the same time, the first microswitch 110 is opened, disconnecting the circuit of the pulse igniter 13, stopping the generation of sparks, and realizing manual flameout.

[0058] In one embodiment, the gas stove described in the present application can be a plug-in gas stove or an integrated stove; and the manual-automatic valve can be used for the integrated control of multiple burners, wherein the multiple burners include but are not limited to single burner, double burner and triple burner, etc.

[0059] In one embodiment, by setting the manual-automatic integrated valve as a double-layer design, the upper layer is the intelligent control knob, and the lower layer is the manual knob, it can realize the combination of manual firepower adjustment and automatic firepower adjustment, realize manual-automatic integrated control, and take into account the intelligent needs and traditional operation user habits, which greatly reduces the use threshold of smart stoves.

[0060] Example 2, see Figure 6 , Figure 6 : is a flow chart of an embodiment of a manual-automatic control method for a gas stove provided by the present application. Figure 6 As shown, the manual-automatic control method is applied to the gas stove described in the above embodiment, and the manual-automatic control method includes steps 201 to 202, which are specifically as follows: Step 201: Detect the rotation amplitude of the intelligent control knob through the rotary encoder, and generate a pulse signal corresponding to the rotation amplitude based on the rotation amplitude.

[0061] Specifically, in a gas stove, the smart control knob is connected to a rotary encoder, which is a sensor that can detect and measure the rotational position of the smart control knob.

[0062] Specifically, when the user rotates the smart control knob, the rotary encoder can detect the rotation amplitude of the smart control knob, that is, the rotation angle of the smart control knob.

[0063] Specifically, after the rotary encoder detects the rotation amplitude, it will generate corresponding pulse signals. These pulse signals contain the rotation position information of the intelligent control knob, such as the rotation direction and rotation amount.

[0064] Step 202: Send the pulse signal to the main controller, so that after receiving the pulse signal, the main controller determines the target intelligent menu corresponding to the pulse signal, and adjusts the valve opening of the motor valve based on the target firepower value corresponding to the target intelligent menu to perform automatic firepower control.

[0065] Specifically, each smart menu corresponds to a specific rotation position of the smart control knob and a specific set of firepower values.

[0066] Specifically, after the main controller receives the pulse signal sent by the rotary encoder, it will analyze and process the pulse signal to confirm the target rotation position of the intelligent control knob corresponding to the pulse signal, and determine the corresponding target intelligent menu based on the target rotation position.

[0067] Specifically, after the main controller determines the target intelligent menu, it will adjust the valve opening of the motor valve according to the target firepower value corresponding to the target intelligent menu, wherein the motor valve is responsible for controlling the flow of gas, thereby controlling the size of the firepower.

[0068] Specifically, by adjusting the opening of the motor valve through the main controller, the main controller can realize automatic control of the firepower, so that the gas stove can automatically adjust the firepower according to the requirements of the smart menu without the need for manual adjustment by the user; in this way, the user only needs to select the corresponding smart menu, and the gas stove can automatically complete the cooking task, making the operation of the gas stove easier and more intelligent.

[0069] In one embodiment, when it is detected that the flameout solenoid valve is in an open state and the first microswitch is in a closed state, the flameout solenoid valve is energized, and the pulse igniter is controlled to perform an ignition operation until the ignition operation is completed, and the flameout solenoid valve is de-energized; wherein, the open state of the flameout solenoid valve is the state of the flameout solenoid valve when the first connecting rod mechanism and the second connecting rod mechanism are in a downward rotating state due to the downward pressing and rotating force applied by the manual knob; the closed state of the first microswitch is the state when the manual knob is in a downward rotating state due to the downward pressing and rotating force applied by the intelligent control knob, driving the connecting rod mechanism to rotate so that the connecting rod mechanism closes the first microswitch.

[0070] Specifically, the flameout solenoid valve is an important component in a gas stove, which is used to control the supply of gas; when the flameout solenoid valve is opened, the gas can flow to the burner.

[0071] Specifically, the opening state of the flameout solenoid valve is controlled by the first connecting rod mechanism and the second connecting rod mechanism. The two connecting rod mechanisms are subjected to the downward rotation force applied by the manual knob, so that the flameout solenoid valve is in a downward rotation state, thereby opening.

[0072] Specifically, a micro switch is a small switch used to detect mechanical position or movement. In a gas stove, the first micro switch is used to detect the position of the manual knob; when the manual knob is subjected to the downward rotation force applied by the intelligent control knob, the connecting rod mechanism rotates and closes the first micro switch, which indicates that the user has rotated the manual knob to the ignition position.

[0073] Specifically, when the flameout solenoid valve is in an open state and the first micro switch is closed, the main controller detects these two conditions and then energizes the flameout solenoid valve. This energization action is to keep the flameout solenoid valve in an open state, and at the same time, the pulse igniter starts to perform the ignition operation; the pulse igniter is a device that can generate electric sparks to ignite gas.

[0074] Specifically, the ignition operation will continue until the gas is successfully ignited. Whether the gas is ignited is usually determined by detecting the presence of flame through a thermocouple. Once the flame is detected, indicating that the ignition operation is completed, the system will cut off the power to the flameout solenoid valve. After power failure, the flameout solenoid valve will remain in the open valve state, but no external power supply is required to maintain it.

[0075] Specifically, after ignition, the flameout solenoid valve is maintained no longer by an external power source, but by electricity generated by a thermocouple; a thermocouple is a sensor that generates an electric potential difference in a flame, and the electricity it generates is sufficient to maintain the flameout solenoid valve in an open state.

[0076] In one embodiment, the user can manually ignite in zero second by pressing down and rotating the manual rotary valve; the manual zero-second ignition process is illustrated as follows: after the manual cock is pressed down and rotated, the flameout solenoid valve is pressed by the connecting rod mechanism to manually open the valve, and at the same time, based on the rotation of the connecting rod mechanism, the first micro switch is supported to close and connect, and the pulse igniter starts to energize for 3-5 seconds. When the pulse igniter is energized, the flameout solenoid valve is also energized to maintain the open valve state. After the pulse igniter works, the gas is ignited in the burner, the pulse igniter is powered off, and the thermocouple generates an electric potential difference after the flame burns, which increases the maintaining current of the flameout solenoid valve to keep the flameout solenoid valve in the open valve state during the combustion process.

[0077] Because the smart gas stoves on the market require users to rotate the manual valve to the maximum fire and then turn on the smart function, however, the smart function can still be turned on when the user is not in the maximum fire state, which will cause the cooking temperature to fail to reach the preset temperature, increase the cooking time, and even cause the food to be uncooked, which greatly affects the cooking effect. The smart function may become a useless function in the eyes of users.

[0078] In one embodiment, when it is detected that the gas stove completes the ignition operation and the manual cock valve is manually rotated to the maximum fire state, the second micro switch is controlled to close, and the main controller is controlled to be in a standby state.

[0079] Specifically, when the gas stove completes the ignition operation, it means that the gas has been ignited and a stable flame has been formed; at the same time, the user rotates the manual plug valve to the maximum fire state, which is usually to ensure that the gas stove can provide maximum firepower.

[0080] Specifically, the closed state of the second micro switch indicates that the manual plug valve has been rotated to the maximum fire state; wherein the closed state of the second micro switch is used to notify the main controller that the gas stove is ready for intelligent control.

[0081] Specifically, in standby mode, the main controller consumes less power and waits for further operation instructions from the user; this state also means that the intelligent control function has not yet been activated.

[0082] In one embodiment, when the main controller receives the pulse signal sent by the rotary encoder, it controls the main controller to perform normal working state, and determines the target firepower value based on the target intelligent menu corresponding to the pulse signal; obtains the current gas stove temperature based on the temperature sensor, calculates the temperature difference between the target temperature corresponding to the target firepower value and the current gas stove temperature, and automatically adjusts the valve opening of the motor valve based on the temperature difference by the main controller to perform automatic firepower control.

[0083] Specifically, once the main controller receives the pulse signal from the rotary encoder, the main controller will change from the standby state to the normal working state, ready to execute the intelligent control task.

[0084] Specifically, the main controller parses the pulse signal, determines the target smart menu selected by the user, and determines the corresponding target firepower values ​​according to the target smart menu. These target firepower values ​​are preset in the smart menu to ensure firepower control during the cooking process.

[0085] Specifically, the temperature sensor monitors the gas stove in real time and the main controller calculates the difference between the target temperature corresponding to the target firepower value and the current gas stove temperature. The main controller calculates the difference between the target temperature corresponding to the target firepower value and the current gas stove temperature. According to the calculated temperature difference, the main controller automatically adjusts the valve opening of the motor valve to adjust the gas flow rate, thereby changing the firepower and making the temperature of the gas stove close to the target temperature, so as to realize automatic control of the firepower and ensure that the gas stove can automatically adjust the firepower according to the requirements of the smart menu without manual intervention by the user.

[0086] Specifically, Figure 7 As shown, Figure 7 It is a gas circuit schematic diagram of a gas stove of an embodiment provided in the present application; the motor valve is located at the total gas circuit position of the left gas circuit of the gas stove, and its main function is to control the gas flow rate of the entire gas circuit; the motor valve can adjust the opening by electric means, thereby accurately controlling the gas supply. Specifically, in the manual adjustment mode, the motor valve is set to the maximum valve opening state, which means that it allows the maximum gas flow to pass through; in this mode, the size of the firepower depends entirely on the valve size of the manual plug valve; the user adjusts the firepower by rotating the manual plug valve to control the size of the outer ring fire and the inner ring fire; only when the manual plug valve is rotated to the position of the maximum valve opening, the corresponding micro switch will be closed, and the intelligent mode can be activated at this time; this design ensures that the intelligent mode will not be mistakenly started in the non-maximum firepower state.

[0087] Specifically, in the intelligent mode, the adjustment of firepower is no longer manually controlled by the user, but by the motor valve; the valve opening of the motor valve is determined by the target smart recipe program on the main controller; this means that the gas stove can automatically adjust the firepower according to the preset target smart recipe, and the user does not need to make any manual adjustments; and because in the intelligent mode, the manual stopcock is already in the maximum opening state, the firepower adjustment is no longer affected by the manual stopcock, which can ensure the accuracy of the firepower adjustment of the target smart recipe and avoid poor cooking results due to inaccurate manual adjustment.

[0088] An example is given for the automatic firepower adjustment process in this embodiment: after the gas stove completes the ignition operation, the manual plug is adjusted to the maximum fire state, and the connecting rod mechanism triggers the second microswitch to close. After the main controller obtains the maximum fire state and the second microswitch closed state, the controller responsible for the intelligent part enters a low-power standby state, waiting for the user's next operation. If the user uses the smart control knob to operate, the main controller will obtain the pulse signal sent by the rotary encoder and enter a normal working state. The user rotates the smart control knob. At this time, the display smart menus set on the outer circumference of the smart control knob will light up in turn. The user presses the smart control knob to select the corresponding target smart menu and execute the target smart menu program, such as making soup, timing, etc. At this time, the gas stove does not require the user to manually adjust the firepower. The main controller compares the target firepower value set on the target smart menu program and the current gas stove temperature detected by the temperature sensor, and intelligently rotates the valve opening of the motor valve to adjust the firepower to achieve automatic trusteeship of the firepower.

[0089] Specifically, through real-time monitoring and adjustment, the gas stove can automatically control the firepower according to the preset intelligent menu to achieve precise cooking control; this automated firepower control improves cooking efficiency and quality while reducing user manual operations.
